What are gas lifts for beds and their differences?

The gas lift on the bed does not compress: reasons

The main difficulty that users have to face is that the gas lift does not compress. Reasons for this problem include:

1. Insufficient weight of the structure.
2. Poor quality assembly and installation.
3. Lack of parts.
4. Poor quality of spare parts.
5. Incorrectly adjusted gas pressure.

It should be noted that ignoring any deviation in the operation of the mechanism can lead to its complete failure, therefore, at the first sign of a breakdown, it is necessary to inspect and repair the structure. You can deal with defects yourself, taking into account all the nuances.

Attention! When folding the bed, do not allow the elements to “jerk”; this will cause the elements to suffer.

Replacement of gas elevator

If the gas cartridge does not compress, and the device is required when using a chair, that is, fixing the device in one position is unacceptable, then a complete replacement of the mechanism is required.

To replace you need:

• prepare a certain set of tools and additional materials;
• familiarize yourself with the work flow chart.

Preparing to replace the gas lift

To replace the gas lift swing mechanism, you will need to prepare:

• new chair lift. You can purchase accessories in a specialized store. When choosing a gas elevator, you should take into account the dimensions of the equipment and the maximum load. If you can’t determine the parameters yourself, you can use the help of sales consultants;
• Phillips screwdriver for assembling and disassembling furniture;
• hammer. To ensure safety, it is better to use a hammer made of rubber. Such a tool will not damage the equipment during operation;
• ring punch;

Punch – a tool for pulling out (so-called “knocking out”) parts from holes

• vice. You can replace the gas lift without a vice, but using a bench tool will simplify the work;
• WD-40 liquid.

Sequence of replacement work

How to remove the old gas lift from the chair and install a new lift? The work is performed in the following sequence:

1. treating all joints of stool elements with WD-40 liquid. This will make the disassembly process easier;

Lubricating units to facilitate disassembly

1. seat detachment.

How to disassemble the chair? Using a Phillips screwdriver of the appropriate size, loosen the bolts securing the seat to the piastre.

Next, the chair is turned over and the seat and decorative casing are removed from the lift using rolling movements. The work can also be done by resting your feet on the crosspiece and using rolling movements to remove the chair;

Detaching the seat from the cross and gas lift

1. disconnecting the lift from the piaster and crosspiece.

The work is done by knocking out the gas lift with a hammer with a rubber tip. To facilitate the process of disassembling the cross and the lift, you can also use a metal drift.

Before knocking out, remove the retaining ring - the pin located on the back side of the cross at the point where the gas cartridge is connected;

Removing the gas cartridge from the piastrum

1. installation of a new gas cartridge. To do this, at the first stage it is necessary to insert the device into the crosspiece (until there is a click indicating the fixation of the element), applying some force, put on the protective and decorative casing and connect the half-assembled structure with the piaster;
2. Assembling the computer chair in reverse order.

You can learn more about the independent process of replacing a gas elevator on a computer chair by watching the video.

Replacing a gas chair lift is not a complicated process, so even a novice craftsman can do the job on his own. If you have all the tools, a new lift and pre-processing, the work is completed within 15 - 20 minutes.

How to check the work?

After installing the gas elevator, the surface of the bed is raised and lowered several times to check the operation of the device. When the mechanism is installed correctly, lifting and lowering occurs easily, smoothly, silently, without jamming.

If difficulties arise with operation, the cause should be sought in faulty fittings or installation errors.

The gas shock absorber is simple in appearance, but requires careful attention to installation and operation. It should be installed extremely carefully and competently. Correct installation of the mechanism will allow you to use the furniture for a long time without worrying about safety and reliability.

Application

Initially, gas lift became an extremely useful solution in the automotive industry. Its installation was carried out on trunks and hoods. The driver himself does not hold the structure, since the elevator performs this function instead. The lifts lifted and held a certain weight, preventing sudden falls, damage, etc.

But today these elements have gone much further. The main areas of application include:

• furniture industry;
• construction;
• production of doors, frames and showcases;
• medical industry;
• production of office equipment;
• weapon;
• aerospace structures;
• robotics;
• household appliances and more.

Elevators can have different sizes, they differ in their design and structure, which allows you to find the optimal mechanism for each specific case.

But we are interested in gas lift as furniture fittings. If you look around furniture stores in St. Petersburg or Moscow, or look through the pages of catalogs in Hafele Shop Ru, you will find a huge number of variations and manufacturers of gas elevators.

What is it and its purpose

A gas lift is a special mechanism designed to lift surfaces connected to it. In terms of its operating principle, this mechanism is similar to automobile shock absorbers.

The gas bed lift consists of the following parts:

• a cylinder whose interior is filled with gas, most often nitrogen. It is important to note that the gaseous composition of the cylinder is under very high pressure, so self-disassembly of this element is not recommended;
• a piston with a rod that serves to transmit the applied force to the external environment;
• oil damper ensuring smooth running due to the shock-absorbing effect.

Lifting mechanisms used to open doors

A kitchen gas lift is a lifting structure related to brackets. It is used in cabinets whose doors open upward. This is not the only way to open facades, but most manufacturers prefer it.

A bracket used to raise or lower a drawer door and fix it in this position is called a gas lift

Lifting mechanisms are one of the most popular types of furniture fittings.

The main advantage of such fittings is its reliability, durability and aesthetics.

They come in different types, different in application:

folding lifting mechanisms - for multi-level facades;

Folding lift mechanism for upper tier with large fronts

Folding lift for tall upper cabinets with two-piece fronts

Parallel lift mechanism

The small swing lift has a small installation size and is suitable for small enclosures, such as above a refrigerator or above a storage cabinet

A mechanical lift is an accessible mechanism for opening furniture fronts up/down

The main purpose of gas elevators is the correct, free, silent and easy opening of the top drawers headset upwards

How to repair it yourself

If the gas lift has stopped working and the mechanism needs to be repaired, to do this it is necessary to establish the true cause of the breakdown.

1. First of all, you need to pay attention to the weight of the structure, since with a small load the mechanism will not work. The spring is compressed in the structure only under full load conditions.
2. Elimination of errors made during the assembly process is carried out by dismantling the entire structure. Re-installation is carried out taking into account the correct selection (adjustment) of parts to each other.
3. The quality of the fittings influences the good functionality of the bed. Therefore, for gas lift installation, it is better to purchase spare parts from trusted manufacturers.

Important! When installing and repairing, you should use the manufacturer's instructions.

In order to make repairs yourself, certain skills and knowledge are required, the absence of which can lead to poor quality work. To ensure that basic repairs do not spontaneously become major repairs, you need to contact experienced craftsmen to do the repairs.

Classification

Selection rules and fittings options for sliding wardrobes: purpose, characteristics

When planning repairs and purchasing new furniture, we recommend that you pay attention to structures that use gas lifts. They increase the level of ergonomics, comfort and operational safety of any furniture several times.

At the same time, there are different areas of application for furniture gas elevators, which is why a certain classification is used

Taking into account the direction of their action, there are 2 types of shock absorbers:

• Direct action. Direct action designs are distinguished by the fact that they compress the operating rod. That is, in the basic assembly state, the rod is in the fully extended position. In the furniture manufacturing industry, these devices are the most common;
• Reverse action. From the name it is not difficult to guess how they differ from direct action elements. How do you think? Absolutely right. Here the gas lift extends into a recessed rod.

There is a classification based on the internal pressure inside the working cylinders. Designs are divided into 2 categories.

• High pressure. They consist of a rod and a cylinder. Inside the latter, as already noted, there is an inert gas. Such an element cannot be disassembled. The work is based on the fact that gas begins to displace the rod from the cylinder. By plunging the rod inside the cylinder, the volume of gas storage used is reduced and the pressure in the spring increases;
• Low pressure. These lifts are made from a pair of hollow cylinders filled with compressed gas. When compressed, the gas increases volume and thereby increases the internal pressure in the spring. Their resource is almost unlimited. Plus, such structures can be adjusted, disassembled and maintained.

Therefore, we recommend that you first ask which GLs are used in the furniture you purchase. If you made the furniture yourself, then all you have to do is buy a suitable shock absorber. Markings are applied and installation is carried out. Buying gas lifts today is not a problem at all. The price for accessories is reasonable, and there is a large selection.

Advantages and disadvantages

Advantages of a gas elevator:

• ease of operation;
• silent raising and lowering of the surface;
• when using liquid nitrogen in the shock absorber, the metal parts of the bed do not rust and the rubber gaskets do not deteriorate;
• convenience and ease of use (no effort required, as is the case with spring furniture);
• reliability (rare breakdowns of gas lifts);
• minimal risk of injury - moving parts are hidden under the casing;
• a wide range of.

The gas lift mechanism allows you to fold and unfold the bed about 20 thousand times, which is an approximate service life of several decades.

Flaws:

• unaesthetic appearance of the bed - gas lifts are partially visible;
• It is impossible to immediately determine the quality of the parts.

The conditional disadvantage of gas lift is the high price . However, it is compensated by a longer service life provided that it is installed correctly.

Varieties

Each manufacturer complements its products with different types of lifting mechanisms, which differ in design, cost and operating period. Also, each device differs in power. Taking into account how a gas elevator works, elevators are divided into the following groups:

1. Manual mechanism. This type of gas lift is the simplest and most affordable. Despite the fact that a device of this type will function for a long time and properly, today they are rarely used to equip beds. This is due to the fact that great physical effort is required to lift the upper element. In addition, such products can cause damage to the bed frame.
2. Spring type lift. A simple system that is very easy to use. It doesn't take much force to lift the bed frame. The disadvantage of this design is that its service life does not exceed 5 years, since after this time the springs stretch, causing the device to stop functioning.
3. A mechanism based on a gas shock absorber. The design operates smoothly, does not emit extraneous noise, and is reliable. If you correctly calculate the load and use the device carefully, it will last more than ten years.

Of all types of devices, the most durable is considered to be a product that contains gas shock absorbers. Compared to other types, such a lift is more expensive. But the high cost is justified by comfort and safety.

Gas elevators themselves are automatic - their operation does not require physical effort or human attention. Or friction - the pressure in such cylinders is much less, which allows you to stop the structure in any position

Do-it-yourself gas bed lift repair

Modern double beds are most often equipped with a lifting mechanism.

This system is called a gas lift; it ensures a smooth lifting of the bed along with the mattress into a vertical position. This feature of the beds makes it possible to remove them if necessary, which significantly saves space during the day. If the bed is in the bedroom, then with the help of such a mechanism access to the linen drawer is provided.

Gas lift

Gas lift belongs to the group of furniture lifting mechanisms that are designed to open cabinet facades down and up without effort - smoothly and beautifully. Also, a gas lift for furniture makes it easy to fix the kitchen facade in a certain position and close it smoothly and silently.

The gas lift design for kitchen cabinets consists of a piston and a gas cartridge. Such fittings are compact, so they do not take up much useful space after assembly.

Depending on the model, all facade elevators are divided into:

The automatic lift mechanism for the kitchen is especially convenient for facades without handles. However, unlike a friction gas furniture elevator, it is not able to lock the furniture door in a certain position when lifting and tilting.

A friction gas elevator costs almost the same as its analogue, and its versatility and ease of use fully justify the investment. In addition, most models of gas lifts for furniture come with closers, which makes them even more functional. Furniture gas lift is one of the most modern oil or pneumatic mechanisms, which has a high level of comfort, reliability and durability.

You can buy high-quality gas lift in Moscow on the MDM website - we offer a wide range of mechanical products and fittings from well-known manufacturers at an attractive price. Please note: the model must be selected individually for each type of furniture. This takes into account not only the size of the facade, but also the material used for its manufacture.

Principle of operation

Gas lifts come in several types, but often those used in beds allow the structure to be opened upward.

There are only 2 main types:

1. Automatic. When the bed is raised, the gas expands, which puts pressure on the piston. The last element, in turn, pushes the bed up, minimizing human effort. For braking, a kind of oil gasket is used inside. This allows you to make the move at the very end of the trajectory much smoother.
2. Frictional. This design differs from the previous model in the absence of a damper. The gas pressure here is also slightly lower. This allows you to stop the structure in any convenient position. Beds are rarely equipped with such elements, since there is practically no need for this.

Operating principle of gas lift

The classic gas spring has a smooth operating stroke.

When the door front opens at least 10 degrees, the gas spring, without your help, will further open the door to the full open position of 90 degrees.

The entire door opening process is controlled by a special hydraulic shock absorber to minimize noise and vibration of dishes in the cabinet.

The gas lift mechanism has so many advantages. What is the reason for this? The secret lies in the design of the device and the principle of its operation.

Let's consider the composition of the gas lift structure

:

• body, cylindrical;
• sleeve;
• piston;
• valve;
• rod, move freely around the body;
• valve to maintain medium pressure in the system;
• sliding bearings;
• stuffing box;
• to create a tightness - stuffing box,
• anther;
• piston seal.

The housing cavity is filled with nitrogen, which is the working medium

It is impossible to open the gas lift with your own hands, but attempts can lead to undesirable consequences. Which can simply lead to damage to the device.

Criteria for choosing a gas lift

:

1. The main characteristic of a gas lift is the compression force, so before purchasing you must know exactly the weight of the door for which the gas lift will be intended. The greater the weight of the door, the greater the compression force of the mechanism.
2. The second selection criterion is the length of the mechanism, which depends on the immediate size of the door that it will need to hold.

One of the significant advantages and at the same time a selection criterion are two types of door opening: automatic and step-by-step.

The step-by-step design is the design we are familiar with, with a handle on the door.

The automatic design is slightly different. With this mechanism, the door opens with one press, and after a while it automatically closes.

This advantage is very convenient and effective, because we are always in a hurry to get somewhere and often forget to close the cabinet doors. This mechanism is also convenient for those who, due to their height, simply cannot reach the door of a wall cabinet.

Modern technologies have made it possible to release completely new models with a more complex and high-tech lift. Kitchen furniture facades are equipped with an electric drive, which allows operation without human effort.

When buying a gas lift, it is not at all difficult to pay attention to these two small criteria, but very important. There will be no problems with the size of the cabinet and the length of the gas lift, but the compression force must be determined in advance.

Calculation of the required gas lift compression force

A load of one kilogram requires a force of 10 Newton. Knowing the weight of your kitchen door, you can easily calculate the amount of force required.

Modern manufacturers sell fixed-load mechanisms to the furniture market: 60, 80, 100, 120 and 140 Newton.

How to replace a lift

First of all, you need to choose a high-quality gas lift for the bed. Once it is selected, you can begin installing it:

• It is necessary to dismantle the old equipment. To do this, you need to unscrew all the nuts and install new gas shock absorbers in the vacant space. The position should be cylinder up.
• Installation must be done with the frame in the open position. First, attach the part that is to be installed on the bed frame, and then attach the mechanism to the frame.
• It is necessary to ensure that all parts are securely screwed to the body.
• After installing the mechanism, you need to check the smoothness of its operation.

To avoid problems with such a mechanism in the future, it is necessary to take into account its characteristics and the quality of the fittings. Then it will last a long time and will not cause any trouble.

Procedure

Precise adherence to the procedure is the basis for proper installation. By following these steps step by step, you will be able to avoid common mistakes that can lead to damage to the product and shorten its service life.

Preparation and assembly of MDF parts

A large number of bed parts are made of MDF. When starting installation, all elements are freed from the packaging film and inspected for damage. If at least one element has defects, replacement is required. A damaged bed frame will not be secure. The parts are laid out at the installation site so that the side with holes for fasteners is on top.

Installation of box and base

The main parts of the bed are the box and the base. First, the perimeter of the structure is assembled, which consists of three walls and a head back. To do this you need:

• connect the walls and the head back to each other using fixing elements;
• a base is placed on the constructed frame, which is usually made using wood and a metal frame;
• To securely fix all components, tighten the screws with a screwdriver.

In some types of beds, longitudinal strength elements may be provided. In particular, solid longitudinal ties, brackets and corners, fixed to the structure with screws, are common

Installing Corner Ties

The purpose of corner ties is to impart reliability to the assembled structure. The screed consists of several elements:

• a corner in the form of a metal plate bent in the central part at a right angle;
• bolts for fixing the plate to the frame;
• threaded bushings.

To connect the two walls of the bed with a corner tie, the plate is placed on the inside at their junction. Then the bushings are inserted and the bolts are tightened first on one wall, and then the connections are aligned and the fasteners are fixed on the adjacent wall. If desired, it is possible to replace the standard model of corner tie with a modern version, for example, confirmat or minifix, which are distinguished by more compact dimensions.

How to install the lifting mechanism

1. Secure the furniture frame to the lifting mechanism. It is recommended to use screws for this. Before final fixation of the fasteners, it is necessary to level the gaps between the base and the frame.
2. Determine the appropriate level of force to operate the mechanism. As a rule, this information is indicated in the attached documentation.
3. Install the structure into the lifting mechanism with the cylinder facing up, using nuts with a locking ring and fluoroplastic washers.
4. Tighten the fixing nuts to the limit, then loosen the fastening slightly, leaving minimal play. After this, you should check the functioning of the lifting mechanism by lowering and raising the structure several times.

Installation of the traverse

The traverse is a special element that performs the function of a screed. Using a traverse, the lower part of the bed frame is fixed. The element is placed along the structure parallel to the longitudinal tension parts. The use of a traverse helps strengthen the structure, ensures stability and durability, and also makes it possible to securely fasten small side elements that most often fail.

Specifications

Gas lifts are unique mechanisms that are used in various fields. Almost all types of systems work on the same principle.

Several technical parameters of these systems should be highlighted:

• The gas lift can be compressed by physical force.
• The systems can operate at temperatures from -30 to +80 degrees. But this characteristic affects the power of the device. A change in temperature of 10 degrees will result in a decrease in this indicator by 3%.
• The operation of the gas lift should not include its movement to top dead center. This can quickly damage the system. Therefore, it is very important to install this structure correctly.
• The rod can move at a maximum speed of up to 300 mm/s. In this case, the pressure inside the cylinder does not exceed 160 bar.

Main selection criteria

To choose the right gas elevator, you will need to determine:

• type of system;
• technical specifications;
• manufacturer.

Types of gas lifts. Their advantages and disadvantages

To assemble furniture we use:

• direct action lift;
• reverse action lift.

A direct-acting gas elevator operates on compression. This is the most popular version of the lifting system, as it is simple to manufacture, lower cost and easy to install.

Direct acting gas lifts

Reverse-action furniture lifts, on the contrary, work to extend the rod. Fittings are more complex to manufacture, as high precision is required during production, which primarily affects the cost of the equipment.

Reverse action furniture lifts

Gas elevators can also vary in how they open. There are models:

• with a step-by-step design, that is, manual opening. The cabinet door or other folding element in this situation is equipped with a handle that facilitates the process of controlling the lifting mechanism;
• with automatic design. In this case, the lift is equipped with an electric drive that drives the lifting mechanism.

Electric furniture lift

Automatic fittings are installed on cabinets located in a place inaccessible to standard opening (for example, high) or where manual control is difficult (for example, due to the heavy weight of the bed). It should be noted that the cost of such accessories is significantly higher.

Determination of technical parameters

In order for a pneumatic gas elevator to serve for a long time, you will need to determine:

• compression force;
• equipment dimensions.

When calculating independently, the compression force of the spring is determined taking into account:

• weight of the folding structure (facade, bed, rising part of the chair, etc.);
• the distance determined from the center of the axis of operation of the equipment to the middle of the lever (center of gravity);
• height between the center of the system axis and the equipment mounting location;
• number of installed lifting mechanisms.

Data and calculation method for gas lift for furniture

In order not to make complex calculations, you can use the recommendations of experts:

• It has been proven that when choosing cabinet lifts, a 1 kg load will require a lifting force of 10 Newtons. Manufacturers produce lifts of different strengths. The most popular devices for kitchen cabinets are 60 N - 140 N, and for sofas, beds, chairs - 1000 N;
• When choosing lifts for other pieces of furniture, the device classes are taken into account.

If the lift class is selected incorrectly, this does not mean that the mechanism will not work. However, the service life of furniture fittings will be significantly reduced.

The next step is to determine the dimensions of the furniture lift. The length of the gas lift depends on the size of the cabinet door or other lifting device.

Popular manufacturers

When choosing furniture fittings, you also need to pay attention to the manufacturer, since the reliability and service life of the equipment depends on the manufacturing company. Currently, products manufactured by the following companies are popular:

Advantages of lift-up beds

Gas lifts are installed in various types of beds. Some models are complex transformable systems. In others, the piston is used only to lift the frame on which the mattress rests.

Several advantages of such products should be highlighted:

Practicality. The space under the bed is perfect for storing things, bed linen, and blankets.

Durability . Gas lifts not only reduce the load on a person, but also protect the bed frame from rapid destruction.

Simplicity. To activate the mechanism, significant effort and special skills are not required. Even a child can do this.

Variety of designs. This type of furniture is very common on the market, which allows you to select products to suit every taste and color. You can find both rectangular-shaped beds and options with a round bed.

Economical. This is achieved due to the fact that the space under the bed can be used as a locker.

How to install

The gas lift is usually installed on the bed during furniture production, but you can also do it yourself. For the work you will need a hammer, a saw, an electric drill with various attachments, metal corners, self-tapping screws and a properly selected gas lift.

How to install the mechanism on the bed:

• First of all, you need to assemble the bed frame. For this, metal corners are used to strengthen the structure;
• Now you can start attaching the lifting mechanism. For this, special screws are used;
• assembly of the folding frame;
• attaching the gas elevator to the folding frame, which must be in the open position;
• checking the functionality of the mechanism. To do this, the gas lift is alternately compressed and decompressed. If there are any inaccuracies in the operation, you must start the installation again, taking into account all the recommendations.

In order to install a gas lift yourself, you will need to take into account many nuances. If you are unsure of your actions, you should contact specialists who will perform all the work efficiently in accordance with the instructions. In order to avoid installation difficulties, you can order a bed with a lifting mechanism. This will allow you to choose the right furniture style, its dimensions, as well as a lifting mechanism with the appropriate technical characteristics.

Adjustment

After the installation of the gas lift is completed, it is time to adjust the structure so that the doors function correctly. It is very important to prevent the doors from touching the ceiling and to make them silent and slow to open and close. To do this, you need to scroll the main fasteners.

In order for the adjustment to be accurate and correct, you need to gradually turn the thread of each gas lift until the doors take the same position.

Due to the use of the described shock-absorbing mechanisms, the service life of kitchen furniture is significantly increased.

Gas lift

Gas lift can rightfully be designated as a bestseller among the mechanisms in this category. It is so popular that it is already a classic, and is perhaps most often used to raise kitchen fronts.

The desired mechanism has many advantages, for which it is given “people’s love.” Here they are:

• obvious ease of installation to facades;
• very affordable cost;
• comfortable operation throughout the entire service life of the device.

Gas lift is one of the most convenient lifting mechanisms for equipping kitchen facades

How to install a gas lift: instructions

Gas lift fasteners are made directly to the following parts of the kitchen cabinet:

• to the side;
• to the facade.

You can easily handle the installation of a gas lift yourself, but if you are not confident in your abilities, trust the professionals.
More precisely, the round part of the part with the bushing goes exactly to the side of the cabinet, and the oblong fastener goes to the facade. A nitrogen cylinder is already snapped onto them, which, by the way, professional furniture makers recommend mounting directly in the upper part.

So, let's start looking at the steps.

Step 1. So, take the front of your cabinet and lay it with the inside facing up, that is, facing you. Now you need to start making markings.

Marking drawing for gas lift installation

To do this, on the side where the loops are located, you need to mark 9 centimeters, and at the same time step back 2.2 centimeters from the edge of the furniture segment. Place a dot at this point. It will later become the center of fastening of the hook-type part. During installation, you need to turn this part directly with a hook into the inside of the facade. It is important to take the size of the parts for the side of the cabinet at least 2.2 centimeters, the thickness will be about 1.6 centimeters, to which the gap is also added.

Markings on the facade

Step 2. Screw the fastener to the facade.

Fastening the fasteners

Step 3. Now it's time to mark the side of our kitchen cabinet. It also needs to be laid on some surface, turned so that its front part is facing up, that is, towards you.

Markings on the side wall

Take a ruler or construction tape and measure from the end at the top downwards about 27 centimeters. From the end located in the front part, measure 1 centimeter into the cabinet.

Step 4. This area is the central part of the fastening; we attach the round gas lift fastener there with self-tapping screws.

Installing the fastener

Step 5. Next, secure the gas lift. At the end of the work, do not forget to install a damper, overhead or mortise type, as desired. Its main task will be to soften the landing of the facade when it has to hit the end of the cabinet during closing. If you don't install it, you will not only be forced to constantly listen to popping noises, but also your furniture will quickly become unusable.

How to adjust gas lift

A façade equipped with a gas lift can have three positions:

• 90°;
• 70°;
• 110°.

If you are short, it can be quite difficult to reach the necessary kitchen cabinet, namely its door, in order to close it from the top position.

To correct this situation, it is necessary to change the arrangement of existing fastening systems on the cabinet door.

Gas lift device

Table 1. How to adjust the façade markings for installing a gas lift

Make the necessary markings and change the position of the fittings. At the same time, do not forget that an error of approximately 5-10 degrees is permissible, and this must also be taken into account. If you still want to perfect the opening width you need, try adjusting the position of the part by eye.

However, you can adjust the angle of the door in the open position much more accurately if you tighten the gas lift cylinder directly. The fact is that inside this part there is a kind of thread. If, for example, you have facades with installed cylinders in a row, sometimes it is very important to adjust them as uniformly as possible. This is where carving comes into play. We rotate the cylinder along it, and at the same time the facade itself either lowers or rises, which is very convenient. This way you can achieve maximum accuracy.

How to correctly select the gas lift load

The lifting force in the case of this part varies within the following parameters: from 50-60N to 180-220N. Provided that it is correctly selected, and the part is also subsequently equipped with various closers or dampers, then using a gas lift, you can achieve smooth movement of the facade when opening and silent closing, in which there will not be even a hint of the annoying knock of the door.

The standard height of traditional kitchen cabinets is 72 centimeters. If you divide this value into two halves, you get 36 centimeters. This is exactly the standard height of the facade, which does not open to the side, but tilts upward.

Next, in the table in the photo, we will consider what gas lift load is typical for facades with a specific standard width. This parameter changes the weight of the door, and, as a result, you need to select a completely different type of gas lift for it.

Gas lift selection diagram

For those facades that are large and heavy, it would be better to install the parts symmetrically on both sides to avoid gradual warping of the door, which would otherwise inevitably occur.

Wide facades must be equipped with two gas lifts, located symmetrically, otherwise the door will gradually warp

Please note: if you are forced to use a strong gas lift, that is, a part whose power will be approximately 80 units, you need to strengthen the upper horizon (the part to which furniture hinges are attached) with something, since when the cabinet is closed, the part will receive too intense load.

What is a gas lift, and why do we need it?

This is a special mechanism used to lift and transform furniture elements connected to it. In its principle, this device is similar to a car shock absorber.

The design features of the gas lift lie in its configuration. It consists of:

• a cylinder filled with gas, often nitrogen; It is important to note that the gaseous composition is present inside the cylinder under high pressure, therefore it is not recommended to disassemble such a device with your own hands;
• a piston with a drain, which serves to transmit the applied force to the external environment;
• oil damper, ensuring smooth running due to the shock-absorbing effect.

The purpose of a gas lift for a bed is not limited to just the ability to store things under the bed. Structures equipped with this kind of mechanisms are able to properly support the spine during rest, eliminating joints and uneven surfaces that negatively affect the musculoskeletal system.

Choosing a gas lift for kitchen cabinets

Gas lifts for furniture are selected according to three parameters.

• Compression force. First, you should determine the weight of the facade - the larger it is, the “stronger” the gas lift should be. Models from manufacturers have a rating of 60-140 Newton. To accurately determine the required compression force, you need to multiply the weight of the door with fittings by ten. This can be done using special gas lift load calculators from the Internet. To lift one kg of façade you need 10 Newtons.
• Dimensions. The length of the lifting structure directly depends on the size of the door being opened.
• Structure. It can be step-by-step or automatic. Step-by-step is a door with a handle. The automatic one opens with minimal hand pressure, and then closes itself after some time; it does not need a handle.

A gas lift is a bracket that raises and lowers the door of a wall cabinet and locks it in the open position. This kitchen mechanism consists of the following elements:

• housing, with nitrogen;
• a rod moving along the body;
• bearings that ensure uniform movement of the rod;
• parts that maintain tightness: bushing, oil seal, boot, sealing element;
• fastening parts.

The rod is attached to the door using all the auxiliary elements. There are different versions. If installed incorrectly, distortions may occur. In this case, not only aesthetics are lost, but also the functional mechanism will not provide its purpose. Before installation, you need to mark the fasteners. The mechanism must match the design of the cabinet. So, if its internal space has a height of 365 mm, then the gas lift should have a length of 355 mm.

When installing a gas lift, the base of the device is fixed in the side of the cabinet in a pre-installed

the intended place. The bracket is screwed into the marked location and the elevator head is snapped into the bracket.

In some designs, the base is a plate with a hole, installed on screws in the side so that the center of the hole coincides with the applied mark. Next, the hinge head is inserted into this hole and secured. The plate must not be deformed to avoid malfunction.

Installation on the inner surface of doors is carried out in the same way. The angle of inclination of the hinge should be approximately 8 degrees. The correct direction is checked with the rod extended to its maximum.

How to install a gas lift system on a cabinet? Before installation you must:

• determine the method of fastening the fittings;
• prepare tools to do the job;
• familiarize yourself with the diagram for attaching the lift to the cabinet door.

Mounting methods

The gas lift can be installed on a furniture cabinet:

1. using fixing pads secured with self-tapping screws. This option is easy to install, but can only be used for products made of wood, chipboard, MDF and analogues;
2. using screws with a locking function. The primary area of ​​use is metal and plastic surfaces.

Types of fasteners

As a rule, self-installation of a furniture lift is carried out on plates, since the installation of screws must be carried out at the furniture manufacturing stage.

Tools and materials

To perform installation work you will need to prepare the following kit:

• tape measure, square, marker (pencil) for applying preliminary markings;
• drill for preparing holes for fastenings;
• screwdriver and screwdriver for fixing the lift.

A gas lift is exclusively an additional device that facilitates the process of using a cabinet or other piece of furniture. The main fittings of a cabinet door are furniture hinges.

Even after installing the gas lift, the main load is taken by the hinges

Gas lift installation

Direct installation is carried out after installing all the cabinet door fittings according to the following scheme:

1. determination of mounting locations for furniture lifts. The location of fasteners is determined in accordance with the planned opening angle of the cabinet door. As a rule, installation dimensions for all situations are indicated in the attached instructions;

Determining lift mounting locations

1. in the marked places holes are drilled, the diameter matching the size of the fastening bolts;
2. fasteners are fixed;
3. The gas lift is fixed on the fasteners. Fixation is considered complete only after a click. In some situations, fixation requires some effort.

Gas lift mounting

You can watch the video for more information about the process of installing the lift yourself.

It is recommended to carry out work on installing a gas elevator before the final installation (hanging) of the cabinet. This will allow you to apply markings more accurately and avoid distortions. It should be remembered that in order to ensure the correct operation of the fittings, it is recommended to install two lifts on cabinets, beds and sofas.

Is it possible to fix a gas lift with your own hands?

Repairing such a part of the structure of any chair is not justified due to the high cost of repair labor - it is easier to replace it with a new one than to repair the old one. But, if you don’t want to waste time on a new mechanism, you can try to fix the problem yourself. This does not require special skills or knowledge - just follow the instructions.

The Ukrainian manufacturer Barski provides all its customers with a 5-year warranty on mechanisms and 2 years on upholstery materials. There are no similar offers on the market. In addition, the main misconception of the consumer is that the warranty cannot be “knocked out”; this judgment does not apply to the manufacturer Barski - all breakdowns due to the manufacturer’s fault are eliminated after the consumer’s request.

When to contact specialists

You need to contact professionals in two cases:

• If there is no desire or time to identify the malfunction using your own resources and resources.
• If you were unable to identify the defect yourself.

With the first option everything is clear. As for the second, we are most likely talking about incorrect distribution of gas in the piston. Its excess or deficiency often leads to problems in work. There are two possibilities here: the base of the bed either lowers too slowly, it has to be pushed down, or it “shoots out,” which can also lead to rapid wear of the part.

It is unlikely that an unprepared person will be able to cope with this problem on his own. To do this, you will need to replace the gas cartridge in the furniture unit using special tools that are available only to repair team workers.

Installation Tips

In most cases, the installation of a gas lift on a bed is carried out at the production stage, at the enterprise itself. But if you wish, you can do the installation yourself. To carry out the work you will need a basic set of tools: a hammer, a saw, a drill with different drills, metal corners, several self-tapping screws. And, of course, you need to purchase a suitable gas lift in advance. For everything to work properly, it is recommended to install the product according to the following algorithm:

1. The first step is to assemble the bed frame. In this case, metal corners are used, which will securely fix all the elements and make the structure strong.
2. Next, you need to install the gas lift using special screws and bolts.
3. Afterwards, the folding frame is assembled and the gas lift is fixed to it. The product must be previously installed in the open position.
4. Finally, it remains to check how well the installed lifting mechanism works. To do this, you need to squeeze and unclench it several times. The design should operate smoothly and silently.

Types of bed bases - characteristics, pros and cons

Self-installation of a gas lift will not cause difficulties and will not take much time. However, if there is uncertainty that everything will be done correctly, it is better not to take risks and seek help from a professional who will do the work. As an alternative, you can immediately choose a bed that already has a powerful gas lift installed. In this case, preference should be given to well-known and trusted companies.
