How_to_disassemble_bar_stool_with_gas-lift_video

Computer chairs have long outgrown their status as exclusively office furniture. Today they are increasingly being purchased for apartments and houses, which is explained by the versatility, ergonomics and durability of the design. But even such reliable products can experience breakdowns, the most common of which are malfunctions in the gas spring. To find out the degree of wear of this part, you will have to figure out how to remove the gas lift from an office chair to repair it or completely replace it. You can cope with the task without professional help, the main thing is to know the features, the operating principle of this mechanism and strictly follow the instructions presented in the article .

Causes of office chair breakdowns

Before you begin making repairs yourself, you must:

• understand the design of a piece of furniture;
• find out which element is faulty.

Computer chair design

The main components of an office chair are:

• seat and back;
• permanent - a contact connecting the backrest to the seat and allowing you to adjust the angle of inclination;
• armrests;
• piastra - the mechanism by which the chair is controlled;
• gas lift providing seat height adjustment;
• cross with rollers, acting as support and moving mechanisms, respectively.

Main components of an office chair

To connect all parts, fastening screws with sufficient strength are used.

Definition and causes of malfunctions

The presence of malfunctions in the operation of a gas elevator (lift, gas cartridge) is indicated by the following aspects:

1. the gas lift does not hold the seat in the specified position;
2. the seat does not lower or rise when operating the control lever;
3. the seat goes down under the own weight of the sitting person;
4. the chair is tilted from its axis to one side;
5. the chair “swings” in different directions.

Signs of a malfunction

The main reasons for the formation of these malfunctions are:

• lack of lubrication in the mechanism. During the entire period of use, the gas lift requires periodic maintenance, which consists of applying lubricants;

For lubrication, you can use any ready-made compounds and/or oils.

Special composition for gas lift lubrication

• natural wear and tear. Manufacturers guarantee the operation of the mechanism for 18 – 24 months. After the specified period, it is necessary to carry out repair work or replace the main furniture units;
• improper operation: exceeding the permissible load level, jumping on the seat, and so on.

How to assemble a computer chair? Video instruction

If you don’t want to read for a long time, we offer you an excellent video “How to assemble an office chair with your own hands”:

And if, on the contrary, you prefer text, you will find detailed instructions with photographs below.

Opening the box

So, you have a large box of components. The specific set of parts depends on the model of the office chair, but there will definitely be:

• Back;
• Seat;
• A mechanism that connects the backrest and seat to each other;
• Lifting mechanism (“leg”) and decorative casing for it;
• Fasteners - and a special key for it (usually a hexagon);
• Support cross;
• Wheels;

In addition, the set may include armrests, additional pillows, etc.

IMPORTANT : All parts are listed in detail in the instruction diagram, which is also located in the box. Before assembling your office chair, be sure to check that everything is in place - if something is missing, immediately take the purchase back to the store. At the same stage, make sure that all components are in order: no scratches, no abrasions, no other problems.

Assembling a computer chair yourself: step-by-step instructions

So, the delivery kit for the chair is in front of you, everything is in order with it, it’s time to start assembling. To properly assemble an office chair, keep three simple tips in mind:

• Try to follow the manufacturer's instructions. With any popular chair Bureaucrat , Chairman , etc. there is always a detailed diagram indicating the optimal assembly order;

• Before assembling, read the instructions for the chair and this article to the end to get a general understanding of the process;

• If at any stage there are problems (for example, the support mechanism does not fit into the crosspiece), stop and look at the diagram again. If you just start pushing, there is a chance of breaking something, so before using force, make sure that it is really necessary.

Assembling the cross

As a rule, assembling an office chair starts from the bottom. The first step is to install the rollers into the cross:

Turn the cross over and place it on a flat surface (the floor is best, but a table is fine). Take the roller (wheel), insert its rod into one of the holes in the crosspiece and press until it clicks. Repeat these steps for each video.

Now turn the cross over, place it on the wheels and press down on the entire structure from above - this way you will make sure that the wheels are tight. Roll the assembled base on the floor, making sure that all the wheels rotate.

Seat

The next step in assembling a computer chair is installing the adjustment mechanism on the seat.

Turn the seat over and place the mechanism on it. Make sure the holes in the parts line up. Take suitable fasteners (it is shown in the diagram for assembling an office chair). Please note: as a rule, there are special washers for each bolt - they must be used, or the fastening will weaken over time.

Screw the mechanism to the seat. Make sure all the bolts are tight, but don't overdo it or you'll strip the threads.

Now we move on to attaching the mechanism that holds the backrest. It will be most convenient to place the seat on the edge of the table - so that the back part protrudes slightly beyond it - then you will not have to hold the part suspended. Screw the backrest - make sure the large adjusting screw is tightened according to the instructions.

And finally, we install armrests (if your chair model has them). The principle is the same: secure them tightly with the mounting screws.

Gas lift installation

In fact, “assembling a computer chair with your own hands” is not a completely correct phrase: the most complex parts have already been assembled. Including gas lift: a lifting mechanism that bears the main load. All you have to do is put it in the special holes on the crosspiece and the seat mechanism.

Remove the protective caps. Many people do not notice them, so after assembling the chair the shock absorber does not work - this is a mistake. Insert the bottom of the lift mechanism firmly into the hole located in the center of the cross.

Place the protective plastic casing on the gas lift. There is no need to attach it; after the office chair is completely assembled, this cover will not go anywhere.

Finishing the assembly

You have one last step left: connecting the support part to the seat.

Carefully and carefully place the adjusting mechanism (it is screwed to the bottom of the seat) onto the gas lift rod. At this step, try not to apply any force at all, the main thing is precision.

Make sure the chair is stable enough and apply gentle pressure on the seat. Then carefully sit on it.

At this point, the actual assembly of the computer chair is completed, but there is one more important step left.

Checking if everything is done correctly

Follow the simple checklist “How to check an office chair”:

1. Is the lifting mechanism working ? Sitting in a chair, press the lever - if the seat goes down, everything is in order. Now get up from the chair and press the lever again, the seat should rise;
2. Is there any extra noise ? Creaks, clicks when the gas lift operates, crackling - after you sit in the chair for a minute or two, nothing like this should happen. If you hear extraneous sounds, then either the fasteners are poorly secured somewhere, or there is a problem with the mechanisms;
3. Are the back and seat level ? There should be no distortions;
4. Does the chair move easily ? All wheels should rotate easily in the grooves of the cross;
5. Is the chair stable ? If you feel that the seat is swaying under you, check the installation of the gas lift - perhaps the rod is not fully seated in the groove.

If everything is in order, congratulations: you have assembled a computer chair with your own hands! Do you agree that this is not difficult? Now it’s time to consolidate your knowledge in practice: choose a suitable computer chair in our store , and forward to comfort!

Gas elevator repair

A gas lift for an office chair consists of the following elements:

• outer casing made of high-strength metal;
• a cylinder consisting of two reservoirs and equipped with a bypass valve;
• a piston with a rod located inside the cylinder and intended for lowering/raising the chair;
• button that is operated by the control lever.

Internal structure of an office chair lift

The gas elevator is a completely sealed equipment and even if a breakdown occurs, the gas cannot enter the surrounding air.

To achieve the specified level of safety in using the mechanism, gas is pumped into the cylinder exclusively under factory conditions. Therefore, you can only do partial repairs of the office gas lift yourself, which boils down to “jamming” of the mechanism in a certain position.

How to repair a gas cartridge by fixing it? To repair a lift and fix the lift at a certain level, you must:

1. gain access to the mechanism. To do this, remove the decorative plug (if any) and the pin - lock - from the lower part of the cross at the place where the lift is attached;

Disassembly to gain access to gas lift

1. the crosspiece with the decorative casing is removed, thereby opening access to the lift;
2. A piece of pipe suitable in length is put on the piston. It is this element that fixes the gas lift in one position. Therefore, it is important to determine in advance the optimal seat height and the required pipe length;

Fixing a gas lift with a pipe cut

For fixation, you can use pipes made of any materials: metal, propylene, polypropylene, metal-plastic, and so on. When choosing a pipe, it is also necessary to take into account the diameter in order to “hide” the mechanism in a decorative casing.

1. The chair is being assembled.

Components of bar stools with gas lift

The standard package of a metal chair includes the following parts:

1. Base. Serves as a support for the entire structure. Monolithic.
2. Direct gas lift.
3. Footrest. In some models it comes as a separate component. In others it is a continuation of sitting.
4. Seat. Made from plastic, natural and artificial leather.

How to replace a broken mechanism? Necessary tools: screwdriver of suitable size and shape, wrench, rubber mallet, backing to protect the base.

Chairs made of metal

Stages of gas lift replacement:

1. Remove the seat using a wrench and suitable screwdrivers.
2. We fix the remaining structure with our feet, pressing it firmly to the floor. Using a mallet, remove the footrest. We direct the blows from bottom to top. Don't hit too hard. A few accurate hits will be enough.
3. Disconnect the base and the gas cartridge using a mallet. Protect the surface with a thick cloth or rubber shield. This will keep it from scratches and dents. Lift the chair into the air while holding it by the gas valve. Apply gentle blows around the entire circumference. It may take several circles, but with this approach it will be removed gradually, without deformation or damage.

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.

Drawing up a drawing

You cannot create products blindly. A drawing with precisely indicated dimensions is required. The standard sizes of bar stools are as follows:

• height to seat – up to 85 cm;
• seat width – from 30 cm;
• The minimum distance between the legs is 40–45 cm.

Types of chairs for schoolchildren, the best brands, selection criteria
Some models require a backrest. Its height should not exceed 25 cm. All measurements are included in the drawing. Dimensions cannot be changed during the assembly and preparation of parts.

The height can also be adjusted based on the height of the stand itself. The distance from the floor to the seat is equal to the height from the floor to the table top minus 30 cm.

Working drawings record the main dimensions and components. If you plan to make a sliding product, all parameters are indicated already in extended form. The diagram itself can be obtained in several ways:

1. Download from the Internet. No one guarantees the correctness of such calculations. There is a risk of wasting materials and getting low-quality results.
2. Create in a computer program. The software allows you to create an accurate drawing of the product. Skills in working with such software are required.
3. Draw it yourself. The easiest way. You will need a sheet of paper and a pencil. But it is advisable to check all calculations several times.

A correct drawing is a guarantee of a good result. Therefore, you should not take the first one that catches your eye. If the choice fell on an option posted on the Internet, it is useful to familiarize yourself with the results of those who have already used this option in their work.

How to repair a broken leg

Repairing broken legs is a common furniture problem. If the element breaks exactly according to the texture, and when combined, all the parts fit perfectly, then it is necessary to apply wood glue to the ends and compress it well using clamps.

How to fix the leg of a wooden chair if it was originally attached with glue, but is now loose? To do this you need:

• remove the leg from the hole;
• remove remnants of old glue;
• apply a new layer of glue to the base of the leg;
• install the part into the hole;
• secure with a weight, placing it on the seat. Excess glue is removed.

It is recommended to use PVA-based glue for repairing the legs of wooden chairs. It must be water- and light-resistant, and also have high adhesive strength.

The office chair lowers itself when you sit down: repairing the structure on your own

Sometimes, while using the chair, a problem arises - the seat lowers all the way when a person sits on it, and does not respond to the lever of the lifting mechanism. In this article I will tell you how to solve this problem on your own. You will learn about the causes of the malfunction and learn how to fix the breakdown yourself.

A special element called a gas lift is responsible for raising and lowering the chair and is installed at the base of the structure.
