It is impossible to do business when sitting in a chair is uncomfortable.

This is why it is important to keep the chair in order.

Before starting work, you must wear safety glasses; particles of the cylinder or lubricant may get into your eyes. If you are replacing a gas lift in the cold season, do not use it right away. It is better to leave it to warm up at room temperature for a day. You need to put something on the floor, for example, a newspaper, so as not to get it dirty.

First, using a shaped screwdriver, unscrew the seat from the swing mechanism. After you have turned the chair over, you need to mark the front side of the mechanism, then unscrew the four bolts and separate the frame from the seat.
Now you need to disassemble the gas lift. We take a hammer and lightly begin to hit the swing mechanism at the base of the gas lift from the side of the cross. It is important not to bend the mechanism. If it was not possible to knock it down, you need to squeeze the base of the gas lift with a vice and turn the swing mechanism.
Now you need to separate the gas cartridge from the cross. To do this you will need a metal drift. Using it, you will avoid unnecessary breakdowns. To make the work easier, spray the bottom and top sides of the cross with WD40 lubricant. You need to turn the crosspiece with the rollers upward and, with careful movements, knock the gas cartridge out of the cone base. It is better to carry out this work with an assistant; it is difficult for one person to do this.
We replace the gas cartridge that has become unusable with a new one. We insert it, applying force, into the hole of the cross. Make sure that the gas cartridge matches the diameter of the crosspiece. The casing is put on the gas lift before you connect it to the seat.
We attach the swing mechanism to the seat with four bolts. It is important to ensure that the front sides of the mechanism and the seat match. We turn the chair over and put the gas lift on the swing mechanism. Now we insert the gas lift into the mechanism and press firmly. Let's check if everything was done correctly. We sit on a chair and watch how the gas lift works.

Everything you need for repairs can be purchased at a retail outlet that sells such chairs.

VIDEO: Is your office chair broken? Cheap repairs

Unlike all cabinet furniture, a computer chair is subject to extremely increased wear and tear, because, in addition to daily use, it contains mechanical and, most importantly, hydraulic elements. For example, it is possible to repair the gas lift of an office chair with your own hands, but first you need to understand the reasons for the breakdown. So for what reason did one user's chair break down after a few months, while for another it lasted for years without the slightest breakdown? How to remove, disassemble and repair a gas lift device? How to remove a gas lift from a bar chair? Adjustment of a lift, gas elevator and its design. We will deal with this in this article.

Causes

Much to your surprise, this circumstance does not always depend on reliability specific model. First of all, it is necessary to pay attention to the weight of the owner, as well as care during operation.

Important! Modern armchairs, as a rule, are designed for a weight of no more than 120 kilograms, and the manufacturers themselves, in turn, provide a guarantee for any malfunction from 12 to 18 months.

From this we can conclude that the causes of failure may be:

careless handling;
failure to comply with weight restrictions;
The warranty period has expired.

But if your chair is broken and the warranty period has already expired, then, with sufficient knowledge and skill, you can easily repair a computer chair at home.

Important! Since you have taken on the task of repairing a chair, it makes sense to clean up the entire workplace. And since computer desk This is usually a bunch of paperwork and little order, then let's start with the main thing - . Next stage- table top:

Self-repair - how possible is it?

If your computer chair lowers itself when you sit down and rises when you rise from it, while the period of raising or lowering can vary from a couple of seconds to a day, this is a sign that gas has escaped from the gas cartridge.

Important! Gas lifts are not subject to any repairs, because their disassembly is quite dangerous for human life.

In this situation, you can fix the chair using improvised means in the required position or change the gas cartridge for a new one.

Important! The price of a gas cartridge is not that high, and it can be purchased at absolutely any specialized store.

So, you have decided to replace the gas cartridge yourself. For this case you will need:

Armchair;
Curly screwdriver;
Rubber hammer;
Metal drift;
A new gas cartridge that will match the length and diameter;
Vise for greater comfort.

Disassembly process to replace the gas lift

If you carry out repairs in the cool part of the day, the liquid in the gas lift may well freeze - using it is strictly prohibited. Wait until the new gas cartridge becomes room temperature. To achieve this you will need to leave it for approximately 24 hours.

First of all, use a curly screwdriver to unscrew the seat directly from the piastres or rocking mechanism.
Turn the chair over and mark the front side of your rocker unit.
Remove the 4 screws that secure the chair seat directly to the rocker mechanism, and then set the chair body aside.
Remove the protective casing, take your gas cartridge into comfortable hand downward swing block.
Using medium-force blows, tap the swing mechanism at the very base of the gas cartridge.

Important! Carefully monitor the degree of bending of the swing mechanism, do not allow it to bend. If you are unable to knock down the block, try securing the base of the gas cartridge in the clamp and turning it.

After removing the swing mechanism, knock the gas cartridge out of the crosspiece.
Turn the crosspiece over with the rollers up and, using a metal drift, knock out the gas cartridge from the cone base of the crosspiece with precise and careful blows.

Important! Be sure to watch for damage to the front side of the chrome crosspiece, as well as the stiffening ribs of the plastic crosspiece.

Reverse process

This way you have disconnected the crosspiece. It means that difficult task behind, now assemble the chair:

Screw the swing mechanism to the backrest seat itself and pay attention to the correspondence of the front sides of the seat and this block.
Next, place the crosspiece on the floor with its wheels, remove the transport cap from the new gas cartridge.

Important! You should see the button, but under no circumstances press the gas cartridge button in your hands, because it is dangerous.

Install a new gas cartridge and be sure to make sure that the diameter of the gas cartridge fully matches the crosspiece.
Place the protective cover and then the chair body directly onto the rocking mechanism.
If everything is in order, press the body of the chair with your hands and recheck all the elements.

Now you can sit on the chair, thereby checking the functionality of the new gas lift.

If you have problems with the gas cartridge immediately after assembling the new chair, it is likely that you received a defective gas cartridge. But before you go and complain to the sales organization and demand that the element be replaced, check whether the gas lift button is locked with a lever from the swing mechanism.
When the gas lift does not respond when the lever is pressed, check whether you have correctly secured the piastres or the swing system, and whether the lever for pressing the gas lift button is damaged.

In all other cases, it will be necessary to replace the gas cartridge.

Important! If, after reading everything about repairs, you have come to the conclusion that, for you personally, it is easier and cheaper to buy a new chair, then do not forget to read the article about

Typically, the question is how to parse office chair occurs in situations of transporting furniture or when repairs are necessary. How to do this easily and quickly? Here are recommendations that will help you cope with this difficult task yourself.

Let's start the disassembly process

Before you begin disassembling the chair, follow these steps:

position the chair so that its back rests against the wall;
stand facing the chair;
rest your feet on the base;
take the armrests in your hands.

Start rocking the chair left and right and at the same time pull up on the armrests. Do not forget about safety nets - if you move suddenly while separating the elements of the chair’s structure, you may fall. If you do everything correctly, such results are possible.

1. The seat of the chair was completely disconnected from the gas elevator.

2. The gas lift (also called an air chuck) has separated from the cross, but is still in the swing mechanism.

In the first case, you should turn the cross so that the gas elevator hits downward. Keep the chair itself suspended, approximately 20-30 cm from the floor. Take a hammer and tap it on the edge of the gas elevator. If you are unable to reach the edge, use a metal tube or chisel. Try not to overdo it with the applied efforts, because inside the elevator, in its very center, there is a fastening bracket. It is very sensitive to shock, so it can be accidentally damaged.

What to do if the air chuck is stuck

But how to disassemble an office chair if it was not possible to remove the gas elevator from the swing mechanism? Position the chair with the lift facing down. Use a rubber mallet to hit the top part sticking out of the mechanism with medium force. It is not recommended to use a regular hammer - there is a risk of breaking the plastic and damaging the gas elevator. When impacting, direct the forces downwards, so you will gradually loosen the gas lift - and it will begin to come out of the swinging mechanism.

You can use another method. Place the office chair with the air chuck pointing upward. Hit the place where it enters the seat part (it is usually made of metal). All subsequent blows should be applied to a new place, otherwise there is a risk of jamming the mechanism. Do not forget that the entire procedure is carried out under a canopy, and the chair should be held by the thin part of the gas elevator. Do not hold on to the thick part - you may accidentally destroy the air chuck, as a result of which you will not be able to pull all its steps out of the seat.

If the gas lift was separated from the chair, you have done most work. Now remove the wheels from the cross. If the metal pin gets stuck in the crosspiece (and this is possible when removing the wheels), remove it using pliers and then reinsert it into the wheel. If it is necessary to replace the swing mechanism, unscrew the four screws holding it in place.

Before starting repairs, familiarize yourself with the mechanism and follow the recommendations. Then you will not have any problems with how to assemble or disassemble an office chair.

Some situations force you to sort it out office furniture and then the question arises: how to disassemble an office chair? All manufacturers include instructions for assembly in the box, but without sufficient experience, disassembly can cause some discomfort.

Now there are enough videos and photos on the Internet about how to properly disassemble an office chair with your own hands. This procedure helps get rid of unnecessary waste money for a new chair, when repairing one of the parts, and will also save space when moving. Also, the need for disassembly arises during repairs, when extra furniture It not only gets very dirty, but also takes up a lot of free space.

If the computer chair did not disassemble long time, then the parts can be tightly connected to each other. To do this, you can lubricate them a little with oil or use electronic devices for unwinding.

Disassembling office furniture alone is not very convenient, and therefore requires the help of an insurer. Small office chair parts can get stuck and may require additional tools to remove them. When using these tools, you must follow safety precautions; carelessness can lead to injury.

Work order

First, prepare everything necessary tools, such as a rubberized hammer, chisel, screwdriver and pliers. Disassembling an office chair will not take you more than fifteen minutes if you strictly follow the instructions. Office furniture, especially chairs, take up a lot of space, which is why it is easier to disassemble them than to pack them assembled. Moreover, transportation solid furniture may damage its original appearance.

After the disassembly process has already been completed, it is imperative to assemble all the parts, because even if one bolt is lost, the product will not last long after assembly.

If you don’t need an office chair, experts advise collecting it and packing it. This way, if necessary, it will look much better and last longer.

A modern office chair is a functional and comfortable piece of furniture, equipped with a rather complex mechanism that sooner or later fails. In such a situation, there are three options for the development of events: purchase a new one, take it to a specialized workshop, or repair the office chair yourself.

As practice has shown, it is quite possible to carry out such work on your own. The only thing that is required from the master is strict adherence to the sequence of actions and implementation of the instructions that will be given in this publication.

Today, there are three types of chairs on the office furniture market:

For the manager
Such a piece of furniture usually has maximum capabilities: a five-beam steel cross; synchronization mechanism (a device that forces the seat and backrest to repeat the movements of the owner); mechanisms for adjusting backrest resistance, seat depth, negative tilt, etc.
For staff
Furniture of this type has more modest characteristics and functionality. Most varieties are lightweight (ensuring high mobility) and are equipped with mechanisms for adjusting seat height, armrests, and back angle.
For visitors
Office chairs of this modification are simply beautiful, stable and comfortable furniture devoid of all functionality. Often they do not even have a rotation mechanism and are produced on four legs, instead of one supporting leg with a cross on wheels.

Design features

Despite the variability of designs and functional content, almost all chairs consist of one set of elements:

Five-pointed cross(base). This part is made of metal or plastic. The first option is better quality and more expensive
Rollers. Just like the crosspiece, the wheels can be made of metal or plastic. However, the mount and internal hinge of any roller are metal
Pneumatic cartridge(gas elevator). The part serves as the leg of the chair and is responsible for its “elasticity”
Rocking mechanism contributes to the axial deviation of the chair and its fixation in one position. On expensive models, a mechanism with an offset axis is installed, ensuring the smoothest swing possible.
Piastra. This element is a metal platform with a lever. Serves to change the height of the seat relative to the cross
Permanent contact– an element that connects the backrest to the seat and is responsible for changes in its position

Most office chair models have armrests. In cheap models, these elements are made of plastic; in more expensive ones - made of anodized or stainless steel.

Common breakdowns

As noted above, an office chair is a rather complex device and any of its structural elements may fail.

Damage to the cross

The problem with this element may be destruction at the junction of the beams. The material from which the cross is made is important here.

As a rule, the base is a hollow structure into which you can insert a suitable size and cross-section polypropylene pipe. It, in turn, must be rigidly fixed to the base and the damaged beam.

Plastic parts cannot be spliced using glue or a soldering iron. due to heavy loads on the paws. There is no point in restoring the integrity of this element. The best option will complete replacement damaged structure onto a glass-filled polyamide base.

In order to dismantle the crosspiece of an office chair, you need:

Remove rollers. As a rule, they do not have a rigid fixation and are quite simply removed from the mounting sockets. To illustrate the process, it is recommended to watch the video:
Dismantle the piastra. Fastening to the seat is done “on a cone”. Disconnection from the gas elevator is carried out by tapping on the attachment point. The right process disassembly of an office chair is shown in the video:
Remove the retaining clip located in the recess of the upper part of the hydraulic elevator.
Knock out the gas lift for repair or replacement of the five-beam.
Note! In case of critical damage or destruction, it is impossible to knock the gas elevator out of the base. In this case, you should remove the working cylinder with the seal and bearing from the “glass”.

The process technology and dismantling device are shown in the video:

Destruction of the swing mechanism

If the chair does not hold the “horizon”, then the problem is most likely in the destruction of the swing mechanism.

Fastening to the seat is done with four screws using a shaped screwdriver. The element is dismantled as follows:

The bolts that secure the rocking mechanism from the seat are unscrewed
The gas lift is knocked out of the device mount.

This element is made of metal.

You can independently solve the problem of a collapsed device by completely replacing it (recommended) or using a welding machine.

It should be noted that most chairs originating from the Middle Kingdom are not suitable for domestic spare parts. This concerns, first of all, the swing mechanisms (size discrepancy).

Chinese mechanisms: 200 x 200 mm.
Domestic: 200 x 150 mm.

In order not to re-drill holes when replacing an element, we suggest using adapter plates. How it looks assembled can be seen in the figure below.

Air chuck failure

The pneumatic cartridge of the chair is a two-chamber structure filled with air. When you press the adjustment lever, the valve stops the flow of air between the chambers.

If, when pressing on the valve, the gas lift rod does not extend, it means that the integrity of the piston, seal, etc. is compromised.

It is important to know! Gas lift cannot be disassembled. If damaged, a complete replacement of the element is required

The dismantling process is described above. To clarify the process, watch the video about replacing the gas cartridge on office chairs:

Enough common cause Gas lift failure is a bend in the adjustment lever, which does not allow pressing on the cartridge valve. In this case, the repair can be easily carried out independently: you need to bend the lever to its original state.

Video: Repairing the permanent contact of the chair

If the contact is loose and the back does not “hold”, you will need to seal the connection. How to do this, watch the video:

As a conclusion

As can be seen from the above, almost all work to restore the functionality of an office chair consists of replacing failed elements. In most cases, any “armed” man can perform such work. Finding the parts needed for replacement is quite simple: all components can be purchased in specialized stores or from companies that sell office furniture. To complete the picture, we recommend watching a video about repairing office chairs with your own hands:
