Small repair of the computer chair. elimination of squeak

Why does a wooden floor start to squeak?

Understanding the cause of the squeak will help determine how to fix the problem

That is why it is so important to identify it at the stage of examining the parquet with listening to the squeak. So why does parquet or parquet board creak? Typically, squeaking is caused by the following reasons:

• the tree dries up, decreases in size;
• the floor receives the maximum load, which leads to the weakening of the fasteners;
• during the installation of the floor, the conditions for the gap between the walls and the boards were not met;
• a big step between lags;
• thin wooden boards;
• air vibrations;
• violation of the rules of operation.

In all cases that are not related to a violation of the lag functionality, you can try to use one of the following methods to eliminate the squeak.

Parquet can squeak both in a certain place, as well as over the entire coverage area

How to iterate over the floor

If it is not possible to eliminate the squeak by simple methods, it becomes necessary to dismantle the coating.

Dismantling

First you need to remove the skirting boards. When re-use is required, they are removed very carefully.

To locate the nails, the plinth is carefully pry off with a pry bar. Then with its help it is recommended to remove the boards

When you remove the bars, they should be numbered immediately. This will help you lay the boards in the correct order. Cracked and rotten boards are numbered and set aside.

Cleaning the base

After removing the boards, it is recommended to carefully remove the base. Otherwise, it will not be possible to establish the reasons for the squeak. If there are cracks in the concrete base, they need to be expanded, cleaned and primed. The damage can be repaired with cement mortar. It is also permissible to use a special putty.

Setting lags by level

It is recommended to set the lags by level. They must be in the same plane. For leveling, a long level of 1.5-2 meters is required. If it is necessary to raise the joists, it is permissible to use gaskets or special anchors. After setting the lags in one plane, they are firmly attached to the base.

Warming and soundproofing

For this, the floor is covered with a waterproofing material. Insulation is placed on top. Its role is played by polystyrene or expanded clay. It is also permissible to use mineral wool.

The insulating layer is covered with a membrane that helps to remove moisture and prevents dust or mineral wool from entering the house. All coatings are attached to the logs with a stapler and staples.

Installing a new coating

Finally, the old boards are put back in place. If necessary, some of them are replaced with new ones. The boards are fastened so as to leave some distance between them. The gap should be 8-10 millimeters. It will help maintain the integrity of the coating as the material expands.

Gas lift replacement

If the gas lift in the chair is still broken, it cannot be repaired. Only replacement will save. If the gas lift has failed and practically touches the floor, then there is no choice: you will have to disassemble the chair and install a new mechanism. But after these not very complicated manipulations, the chair will last longer, and it will cost clearly less than purchasing a new one. Be sure to make sure before buying that the new part will fit the chair model.

Replacement procedure:

1. First unscrew the seat screws and remove it from the mount.
2. Use an annular drift to remove the gas lift. It will be easier if you support the cross on the table, for example.
3. A hammer can be used, but be careful not to damage the chair.
4. Fasten the cross securely and install a new gas lift.

A few more tips for use and care:

1. If the chair is secured by the rocking mechanism, do not swing in it under any circumstances. Thus, you can quickly lose the gas lift or even the entire chair: the mechanism is severely damaged and stops functioning as it should.
2. If you still have a valid warranty, you better use it, do not try to repair the chair yourself (lubrication does not apply to repairs).
3. Before lubricating the gas lift, make sure it is in good working order, otherwise it may jump up sharply and injure you.
4. If the material itself creaks, alas, only the purchase of a new chair will save. However, it is naive to believe that a chair made of cheap plastic will last a long time without squeaks.
5. For long sedentary work, it is better to choose a chair of German or Italian production, as well as Polish and Russian. Asian models are still lame in terms of quality, and are more likely to be wasted money.

Operating instructions

In order to fix a defect that has appeared in the refrigerator, you must perform a number of actions:

1. Identify the squeaking hinges on the door.
2. Lubricate them with a special agent prepared for this purpose.
3. Check the door for squeaks by opening and closing it.

Preparation

For work, you need to prepare tools and materials:

• screwdriver;
• petroleum jelly, mineral oil or paraffin;
• a brush, dropper, syringe, or cotton swab;
• rubber gloves.

Buy the lubricant in a convenient bottle with a long, narrow nose. If it is not there, prepare an oiler, syringe or pipette, with which it will be easy to deliver the lubricant to the destination.

Remove all food and items stored in the refrigerator door. It is opened and hinged up to the stop. For convenience, the work is best done together. If necessary, the door can be completely removed from its hinges. They are cleaned of dust, dirt, old grease with a brush, cloth.

How to apply

A small amount of petroleum jelly is applied to the hinge and evenly distributed over the entire surface. To do this, use a small flat head screwdriver.

To apply paraffin, it is heated and the problem areas are lubricated with a brush or cotton swab.

Particular attention should be paid to areas that are heavily worn or start to corrode.

After lubrication

After the grease has been applied, remove the excess with a cloth capable of absorbing it. The door is lowered into place or hung if removed from the hinges.

Examination

To check, you need to open and close the refrigerator door several times to make sure there is no squeak. If the procedure does not help, and the door still creaks, you should remove it from the hinges and more thoroughly lubricate the hinges so that the grease penetrates to the rubbing parts and its amount is sufficient. After that, the door is hung again and tried to open and close. The absence of a squeak indicates that the lubricant has reached problem areas.

Adhesive surface treatment - what is the right way?

We are talking about filling with a special glue to get rid of the squeak of the parquet. To achieve a positive result, you need to prepare a set of tools for work in advance:

• electric drill (drill 2 mm);
• masking tape;
• syringe;
• polyurethane glue;
• rags;
• wax crayons;
• dowels.

The repair begins with the markup. To do this, at a distance of 15 cm from each other, points are outlined and masking tape is applied to them. Holes are prepared in the marked areas using an electric drill. Glue is poured into them with a syringe, filling the voids between the base and the parquet surface.

A regular syringe is suitable for pouring glue.

It will take several hours for the glue to dry. After that, you can remove the tape and glue traces with a solvent.

To enhance the effect, the parquet is pressed to the base with a load and for some time does not come into contact with the repaired area. A day after filling the holes with glue, proceed to the final stage of repair - using wax crayons

It is important that they are as similar to parquet in color as possible. They fill the holes and polish the finished floor with a rag.

Necessary repair tools

To repair a computer chair and eliminate unwanted sounds, you will need the following tools:

• screwdrivers - Phillips and straight;
• hexagon;
• pliers;
• hammer;
• special furniture grease;
• spare fittings.

Most often, you will not need to change any parts of the chair, they rarely break. All repairs will consist of lubricating the mechanism or tightening the bolts. The best lubricant is WD-40 spray. If it was not at hand, or the remedy does not help, you can use any oil lubricant or even ordinary petroleum jelly.

Keep out of direct sunlight

Exposure to direct sunlight will dry out and discolor your reed furniture over time - and drying out is what will lead to tears and breakage in the structure. Instead, you want to keep it hydrated.

One way is to keep your figures in a room where you have a humidifier, or, if you live in a humid climate, on a covered porch. Katherine equated ideal conditions with a cigar humidor.

It is better to bend the latches from the side of the entrance of the guides, but you do not need to bend them too much, since they are soft and reluctantly get up to their original position.

Now we disassemble the mechanism and pay attention to the serviceability of its elements. In my case, the spring was broken, which is responsible for the smoothness of the backrest tilt, and everything else was intact

It is difficult to find such a serviceable spring, so we do without it, but we also don’t throw out the broken one, since it is needed for the mechanism to work.

How to remove and replace with your own hands

It is quite difficult to replace the gas lift on your own. At the same time, you should not immediately start repairing this part if you have problems with the office chair. The failure of the chair position adjustment mechanism is indicated by the following phenomena:

• the seat does not hold in a given position;
• after pressing the lever, the chair does not rise or fall;
• the chair is lowered immediately after the person sits down;
• the vertical is broken (the seat deviated to one side);
• the seat dangles from side to side.

The procedure for repairing and replacing the gas lift depends on the type of office chair. In this case, regardless of design features, the procedure can be carried out using a Phillips screwdriver and a rubberized hammer. It is highly not recommended to repair the gas lift yourself. This mechanism contains a gas hazardous to health. And, in case of damage to the structure, the latter, once it enters the human body, will cause acute poisoning. Therefore, in the event of a breakdown, this part is replaced with a new one.

When buying a gas cartridge, you need to be guided by the dimensions of what is installed in the office chair. Some parts of this type are available with a high taper.

Plastic Models

To fix office furniture, you need to disassemble the seat. But before starting work, it is recommended to process the WD-40 bolts. Lubrication will make the fasteners easier to unscrew. The disassembly process is as follows:

The seat is unscrewed from the base (piastres, rocking mechanism, and so on).
The plastic casing that covers the piastre is removed.
4 bolts are unscrewed, and the seat is removed.
With blows of a hammer in the place of attachment of the piastra, they are disconnected from the seat
At this point, it is important to ensure that the rocking mechanism does not bend.

The last stage of work must be carried out with utmost care, trying not to damage the details of the office furniture.
It is recommended to tap with a hammer from different sides. A metal drift can facilitate this process, by means of which the crosspiece and the lift are disconnected.

The last stage of work must be carried out with utmost care, trying not to damage the details of the office furniture. It is recommended to tap with a hammer from different sides.

A metal drift can facilitate this process, by means of which the crosspiece and the lift are disconnected.

At the end of the described process, you need to knock out the gas cartridge. To do this, the cross should be fixed on a flat surface or use the help of another person. The gas lift is knocked out by point strikes on a metal drift installed in the center of this part

At this stage, you will also need to be careful, as the hammer can break the plastic parts of office furniture.

Metal base

To repair office furniture with a metal base, you need to follow the above algorithm. But in this case, it must be borne in mind that a number of manufacturers use fragile material in the manufacture of the chair. Therefore, hammer blows should be weak. Otherwise, in addition to the gas cartridge, you will have to change the crosspiece.

If the hammer blows did not lead to the desired result, the base of the part must be clamped and turned several times to the sides, swinging the mechanism.

Design features

Before assembling an office chair, you need to familiarize yourself with its main features.

The main feature of such furniture is the mechanisms installed in it. They are used to manually adjust the tilt angle. backs and seats... Some types of chairs have a special swing system that allows you to set any position of the product. With its help, it is possible to adjust not only the angle of inclination, but also the rigidity of the swing of the rear backrest. There is also a gas lift in the office chairs, which is responsible for adjusting the height.

How to do it yourself

To adjust the parameters of the chair, you should carefully study its structure. Some models do not provide for one or another regulatory mechanism. And without them, it is simply impossible to set a certain slope for the backrest, the height for the seat, and both for the armrests.

The delivery package of the furniture product should include instructions that will help you adjust it for yourself. However, you can use general recommendations. First you need to decide on the height of the workplace and the depth of the chair. After that, you can start adjusting the back. When everything is ready, all that remains is to adjust the tilt angle and the level of the armrests.

Height change

To change the height of the workplace, you need to use the lever, which is usually located under the seat on the left side. Sit in an office chair and pull the handle up. In this way, the furniture is lowered to the required level. Next, you need to put your palms on the tabletop, and if it suddenly turns out that they are above the elbows, then the position of the chair needs to be corrected again. To do this, stand up a little and pull the handle again: without weight load, the seat immediately rises.

If the user cannot figure out how to lower or raise his computer chair or office chair, and he cannot perform the necessary actions, the problem may be as follows:

1. This is not a conventional, but a pneumonic model. To raise the chair, or vice versa, to lower it, the lever must be shaken (pressed several times).
2. The design has two adjusters, not one. Each is responsible for a specific mechanism (raising or lowering).In this case, it is recommended to carefully study the instructions before adjusting.
3. The rotating arm only rotates in one direction. If the chair only rises when adjusting the seat height, you must continue to rotate the handle. After a few turns, it will begin to go down.

In some cases, the problem may be structural breakdown. For example, if the height of the chair changes only under the weight of a person (it lowers when he sits down and rises when he gets up), the cause of this phenomenon is the cartridge gas malfunction. It will need to be replaced. If the lever of the new computer chair is not working properly (when pressed down), it may have been damaged in transit. It needs to be examined and corrected with pliers.

Backrest tilt

If there is a screw on the back of the chair, it will allow you to tilt the backrest. The adjuster should be loosened by turning slightly counterclockwise, and then sitting down and leaning back and forth until the most suitable position is found. After that, the angle of inclination should be fixed by twisting in the opposite direction.

Armrest tilt

The armrest adjustment mechanism is usually located on the left side. To adjust the height, you need to hold down the button, then raise the armrests to the desired level, and then release the held key.

Another question is how to adjust the slope. This is done with a special screw. When scrolling it, the angle of the armrests will change. If such an adjustment mechanism is not provided for by the design, the actions can be performed using a conventional screwdriver. You need to act according to the instructions so as not to break fragile parts.

To work at a computer or any other activity in which a person's hands are constantly on the table, you need to adjust the height and tilt of the armrests

It is important that the worker's elbows are at a 90 degree angle. If support is not needed, then it is better to remove or expose these structural parts so that they do not interfere (lower or tilt as much as possible at an angle of 45 degrees)

Some office chair models also offer different adjustment options. For example, the armrests can be moved apart and moved in relation to each other. In addition, the user can be given the opportunity to select specific modes, the number of which ranges from 3 to 10.

Where does the creak come from

The design of a computer chair is a rather complex mechanism, so a squeak can occur for various reasons and at any stage of operation. There is no need to rush to return the purchase back to the store, it is worth finding out the reasons and, if possible, eliminating them.

Among the main factors for the appearance of a squeak are often called:

• weak bolt tightening even at the assembly stage;
• abrasion or drying out of the lubricant of the joints and bearings during operation;
• the parts of the chair were of poor quality, broken or damaged as a result of use;
• obstruction of dust and dirt to the operation of mechanisms in normal mode.

A squeak may appear at different times:

• when a person sits on a computer chair;
• in the event of a chair turning or rocking.

Most often, sounds come from under the seat. Finding out the place of the squeak and the reason, it will not be so difficult to fix the problem.

Frame

The creak can emit the frame of the computer chair. The instructions for use recommend periodically tightening the bolts and checking the integrity of the mechanisms. This procedure should be carried out at least once every six months. In addition, it should be taken into account that the fasteners are only put in place after the chair has been used under full load.For this reason, after purchasing and using it for a couple of weeks, it is worth picking up a screwdriver or hex wrench and tightening the bolts. The main thing is not to overdo it, twisting it all the way and no more. With constant loosening of the bolts, experts advise using a thread sealant.

Swing mechanism

In addition to the frame, the rocking mechanism may squeak in the computer chair. Loose bolts or fragile grease, which often dries up when computer chairs are in stock, are also the cause.

The entire swing mechanism consists of several parts:

• multiblock - almost never squeaks, designed to fix the rigidity and tilt of the back;
• knee mechanism - needed for swinging, requires lubrication;
• top-gun - rocking chair, has a screw for adjustment;
• permanent contact - adjusts the angle of inclination of the back of the computer chair and its pressing against the back of the seated person, has a spring included;
• slider - thanks to it, they regulate the planting depth.

All elements of the swing mechanism require periodic lubrication.

Back

Most often, the back of a computer chair creaks. To remedy the situation, it is worth unscrewing the figured screw from the permanent contact and the screws that attach the plastic cover. The latter is carefully lifted up. After the release of the fasteners, remove the lining. The metal insert must be secured with 4 screws. Most likely, they are not twisted tightly or some of them are lost. By replacing and tightening the bolts, the squeak situation can be corrected.

Gaslift

One of the most common causes of the unpleasant squeak of a computer chair is a gas lift problem. He is responsible for adjusting the seat height. If, after sitting on an office chair, an unpleasant creak is heard from below, it is worth lubricating the gas lift.

Another test for gas lift problems is to detect squeaks when the seat pivots and rotates under load. The gas lift should be inspected and lubricated if necessary. If the problem persists, it should be replaced.

Wheels

The office chair has castors. But they rarely become the cause of the squeak. More often they stop rotating as they become clogged with dust or dirt. The wheels are accessible for inspection, so it is worth cleaning them periodically.

Design features

Before proceeding with the repair of a computer chair, experts recommend that you carefully study the types and design features of such products. In specialized stores, you can see the following models of computer chairs, which have individual design features:

• for the head - a five-beam hollow cylindrical base, a multiblock for adjusting the back resistance, seat depth and roll level;
• for employees - light weight, multi-block for adjusting the height of the seat, armrests and backrest angle;
• for guests - four legs, a comfortable seat and back.

Despite the variety of models, all computer chairs have a similar design, which consists of a number of components.

A five-beam cross is a plastic or metal part that supports the entire structure.

Rollers are iron or polymer parts that are installed along the edges of the base. The maximum number of rollers is 5. A distinctive feature is the presence of metal fasteners and a hinge.

The process of dismantling a part depending on the type of base

If the structure has ceased to rise and be fixed in the desired position, it means that the gas lift on the office chair needs to be repaired. You can do it yourself. The algorithm of actions will be almost identical for both plastic and metal bases.

Plastic

The dismantling of the structure, the base of which is plastic, occurs in a certain sequence. If a person changes the gas cartridge for the first time and does not know how to remove the gas lift from office chairs, he will need an assistant.Instructions:

1. Remove the bolts under the seat. Carefully remove it from the mountings.
2. Stand on the crosspiece, gradually, with swinging movements, pull the chair up by the armrests. Put it aside.
3. Use a rubber hammer to apply a few light, precise blows to the structure body from the side of the cross - the gas lift should come out of the base gradually.

After that, you need to replace the part and perform the same actions in reverse order.

Metallic

The principle of dismantling the gas spring from the metal base is similar to the previous one. The only difference is that some manufacturers use a fragile material in the manufacture of the structure. Therefore, it is recommended to be careful when knocking out the gas lift. The blows should be light so that the cross does not crack.

In fact, do-it-yourself gas lift repair for an office chair is a simple process. If you approach the solution of the problem responsibly and study all the nuances, you can repair the furniture yourself and very quickly, and not spend money on a new product.

Ready

How to fix the problem

To repair a computer chair, you will need tools:

• a set of screwdrivers (straight and Phillips);
• hex key;
• hammer;
• furniture grease;
• pliers;
• spare bolts and nuts.

Due to the squeak, it is rarely necessary to replace parts. More often, to fix the problem, it is enough to tighten the bolts harder and lubricate the mechanism. To do this, you can use both specialized tools and improvised ones - mineral oil or petroleum jelly.

Lubricating Office Chair Parts

To lubricate the parts of a computer chair, you must:

1. Prepare petroleum jelly, solid oil or WD-40 preparation, which contains mineral oil and a solvent to enhance sliding.
2. Turn the chair over.
3. Find the retainer in the center of the cross.
4. Remove the washer.
5. Take out the gas lift.
6. Lubricate washer, bearings, gaskets.
7. Reassemble in reverse order.
8. Turn the chair over.

Replacing fasteners

Prolonged use of the office chair can cause the fasteners to loosen and make a squeak. To eliminate the problem that has appeared, turn the computer chair over and tighten the bolts until they stop using a screwdriver or hexagon. Most often 2-3 bolts are located on the armrests, 4 - on the swing mechanism, the same amount on the seat. There may be more or less of them. It all depends on the type and design of the office chair.

If, when tightening the fasteners, it turns out that some bolts are scrolling, they are removed, a special sealant is poured into the hole and quickly screwed back. Instead of a sealant, PVA can be used. In this case, the waiting time should be increased until the glue is completely dry.

Gas lift replacement

If the gas lift breaks down, lubricating it will not improve performance. If it not only makes a creak, but also fails, replace it. After such manipulations, the office chair will last a long time and the cost of repairs will be more profitable than buying a new one.

Before you buy a new gas lift, you need to make sure that it fits your computer chair model. When replacing it, a number of actions are performed sequentially:

1. Unscrew the screws from the seat.
2. They press the crosspiece with their feet, and the seat is taken by the armrests and, swinging, is pulled up.
3. To remove the gas lift, use a rubber hammer and ring punch.
4. A new gas lift is being installed.

It should be remembered that blows with a hammer when removing the gas lift should not be strong, so as not to damage the cross.

Wheels

To repair wheels you need tools:

• screwdriver - for removing screws;
• lubricant - for processing rollers;
• hammer - for removing parts from fasteners.

If dirt accumulated there is the cause of the squeak of the computer chair in the wheels, you should disassemble them, clean them, lubricate and reassemble them. For this you need:

1. Turn the chair over and try to clean the wheels with a screwdriver, scissors, or other available tools.
2. If it was not possible to remove the dirt, the wheels are removed from the crosspiece by unscrewing the bolts.
3. Wheels are rinsed with water, cleaned, and inspected for damage and wear.
4. If further use is impossible (damage, cracks), there is nothing left to do but replace the parts.

When replacing wheels, experts advise buying a complete set and replacing all 4 so that the wear is uniform with further use.

Scheme of work

In the unloaded state, the central cylinder of the gas lift is located in the upper part of the structure. If a person sits on a chair and presses the lever (button), the mechanism begins to lower, pulling the seat down. After that, the cylinder returns to its original position. When you press the button without loading the seat, the air inside the gas lift pushes the rod up. At the same time, the seat begins to rise.

Understanding the mechanism's operation scheme allows you to immediately exclude other breakdowns of the office chair. In case of failure of the gas lift after pressing the lever (button), the seat does not move.

Description and purpose

A gas lift (gas spring) is a part of an office chair that pushes out a metal cylinder under the pressure of compressed air. The latter adjusts the position of the seat (that is, it allows you to raise and lower the seat). Sometimes a gas lift is compared to a shock absorber. But these details have nothing in common. Shock absorbers dampen vibrations, while gas lift performs other functions.

Structurally, this mechanism consists of the following components:

• metal case;
• a cylinder consisting of two gas tanks and complemented by a bypass valve;
• piston and rod, located inside the central cylinder and allowing the chair to move up and down;
• buttons by means of which the position is adjusted.

Gaslift performs several useful functions:

1. Helps to choose the appropriate height of the office chair in accordance with the person's height.
2. Provides chair rotation around the axis.
3. Partially extinguishes the load that the human spine is experiencing.

The gas lift is a completely sealed cylinder. The gas contained inside is pumped in during the production process. For the manufacture of this mechanism, high-strength steel is used, capable of withstanding various types of external influences, including strong impacts. In this case, the gas does not come out.
