The chair has pretty complex mechanismwhich is subjected to considerable loads and often fails, it often requires setting or fixing. This article will consider ways to repair an office chair with their own hands, without addressing the workshop.

The cup of all breaks: rollers, crossbars and gas lift. In the case of rollers big problems not. The easiest way out is to replace the broken roller on a new one or if it is possible to smoke it superclaim. Often the cause of the malfunction is the garbage: threads, hair, etc. Then it is enough to remove the rollers and clear the places of their fastening from clogging. If a broken jack of fastening axis of the wheel is broken - it is possible to replace the cross.

Highlighting cross-shirts

Repair of the office chairs crosses with their own hands is quite possible in some skills in the mechanics. To do this, you need simple tools and attentiveness.

The material of the crosses is important - if it is made of plastic, it is better to put a new one. Plastic after repair serves even worse than the new and restoration of such a fragile detail has little meaning. Pay attention to the type of plastic, change the polyethylene crossbar is better on the glass filled polyamide. To. This material is stronger and serves longer than ordinary plastics.

Disconnect the cross from the chair

To fix the crossbar it needs to be removed and this process is not as simple as it seems. Often the part itself and the gas elevator are damaged, especially if you act with a hammer or sledgehammer. Be sure to take the rollers because they are often damaged during disassembly and repair. The tool will be required:

• A hammer
• Kiyanka
• Screwdriver

The floor is better to be clogged with rags or newspapers to protect it from lubrication. To disassemble the tight compounds, especially gas cartridge with a cross, it is convenient to use WD-40 liquid, gasoline or simply soapy water. Attention! It is possible to shoot down a cross with a hammer, only if it is metallic, it is necessary to use a Cyanka for plastic. We recommend watching a video repair of an office chair.

Procedure

• We remove the wheels. Usually they do not have rigid fixation and are easily removed from the attachments.
• I turn over the chair, it is necessary to put it on the stool for stability so that the back is resting in the floor.
• You need to disconnect the swing and adjustment mechanism - to pianast. We unscrew the 4 screws fastening it to the seat. Then you need a light tapping to knock it down from the Gazlift, since it is usually a compound without thread, conical. It is advisable to act with a wooden or rubber image and do not beat on the edges of the details, they are easily deformed. If the connection is "Cracked", you can use a special fluid or carefully catching up with a hammer.
• Remove the locks of the cartridge gas. The locking clip is located in the center of the deepening for the cartridge, it needs to be carefully pushed and remove it. Then you need to remove the puck and postpone along with the clip. Now disconnect the gas elevator rod. Careful! Inside the glass can stick to the lubricant of the gas lift: 2 washers and a bearing gland. Postpone them aside and do not confuse with the pile of a stopper when assembling.
• Know the cross. Especially carefully you need to be with plastic. Beat better than a miley or ordinary hammer through a tree, easy blows from all sides.

This work should be made extremely neatly and carefully, with the negligent work of the neurofesional, the piastr and gas is often broken.

For assembly, you need to do everything in the reverse order.

• Repair of the sovereign of the office chair does not always make sense if it is plastic. Glue and soldering with a special soldering iron for plastic strength do not provide, they can be used except for sealing small cracks.
• It is possible to attach a broken leg of the cross with a metal or plastic overlay. Sometimes it uses a plastic tube of suitable diameter and fix it with glue or screws.
• For broken or cracked metal crosses the best way - Welding.

Hying of a gas elevator in an office chair

Repair of the Office Chair Gaslift will help save a considerable amount on the service of the wizard or buying a new thing. At the same time, it is necessary to clearly determine the cause and seriousness of a malfunction, in many cases the easiest way to replace the entire cartridge. Detail is not cheap, but new furniture Many more expensive.

When the chair begins to raise arbitrarily and the lifting lever does not work - these are obvious signs of damage to the cartridge gas. We check it like this:

• You need to unscrew the seat and see whether the lever is pressed on the gas cartridge valve. In a serviceable mechanism at pressures, the valve goes down, the gas cartridge is extended.
• The problem sometimes lies in the lifting lever. Then you can neatly straighten it to the initial state.

For repair or replacement of the gas elevator, the chair is fully disassembled. The process is described in the first part of the article (repair of the office chair crossmen). Set new detail It's much easier than to extract broken, most importantly, without having to beat the hammer.

METHOD OF REPAIR OF GAZLIFTA

• It is necessary to determine the height of the armcha optimal for you. Measure and record the result.
• You need to remove the crossbar and disconnect the cartridge from the pianst, before reloading the seat.
• Then the glass is removed and the details are removed consistently: the washers, bearings, etc. They are important not to confuse and remember the installation order.
• Then you need to choose a tube or hard hose from plastic suitable to the axis of the inner diameter elevator. The tube will have to cut off the height of the chair convenient for you (this is done in the first step). For this purpose, you can use a plumbing tube made of metallized plastics.
• The resulting part is put on the rod and all the parts of the cartridge are installed in the reverse order.

After assembly, the chair should behave normally. This method will help to restore the minimum performance of the chair and prevent "failures", but the gas lift will not work as new. In general, its full replacement is the best option, for cheap and medium-sized chairs, the cost of this spare part will not be high.

Very comfortable for computer table On a comfortable office chair. This piece of furniture is very popular among office workers And just comfort lovers. But some consumers after some time lapse are puzzled by the imperfection of the selected item. For example, most often the office chair goes down - how to fix it we will tell in this article. Tell how to repair and adjust the gas lift, how to raise the height and make it not spinning. Why does the chair keep height spontaneously when you sit down?

We are engaged in the repair of the chair on the wheels

This type of furniture is most susceptible to quick wear than the same Soviet wooden chairs. Daily exploitation quickly crosses the mechanisms and hydraulic parts, of which the design consists.

But then another occurs interest Ask: Why is some chairs break in two months, and another is not the first year? Often this circumstance is due only to the quality of the materials of a particular model. First, of course, you need to pay attention to the fact that modern models Cauls can withstand only up to 130 kilograms, and the manufacturer provides a warranty somewhere for 12-18 months.

But if it happened so that the chair is broken, and the warranty card has not been acting a long time, then with a small snarling you can do recovery work and independently.

Important! If you are not sure about your abilities, then better contact special service centers.

Problem and its decision

If it happens that the seat itself falls when you are trying to pressent more comfortably, and rises synchronously with you, and this period of lifting or descent varies from one second to twenty-four hours, the problem clearly lies in Gazpartron's released gas.

Important! The gas belts themselves are not refundable, since the disassembly of such a component may be attendant.

In this case, you will have to take the injured furniture, fix it in the most convenient position and begin to replace the old gas cartridge on the new one.

Important! The cost of such a detail is small, which significantly reduces the costs of all work.

If you are still wondering how to fix the office chair, you will have to prepare a little.

What will come in handy?

In order to fix the office chair, if it goes down, you need to get the following tools:

• Furniture chair.
• Set of different screwdrivers.
• Kiyanka.
• Fucking metal material.
• A new gas cartridge that is suitable in size to your furniture.
• Things that will make a little easy process of work.

Important! If for some reason the repair occurs in the cold, that is, the probability that the liquid in the gas elevator has frozen, and in this state it is impossible to use this part. Wait full heating to room temperature (it may take about a day).

We replace the broken component

Well, for a successful result it is worth following such advice:

• We take into the hands of a curly screwdriver and proceed for disassembling the seats from a special mechanism "Rashchka", or piastra. Just turn the office chair, mark the side of the swing mechanism on the front part and unscrew the four screws that fix the seat of the chair to this mechanism. Case can be removed to the side.
• Remove the protective casing and take the gas cartridge in your left So that the mechanism looked down. Apply a blow middle powerhaving tapping the base of the gas elevator. Make sure that the mechanism itself is not deformed.

Important! If dismantled the design did not work, then use the vice and check the installation.

• If the design has been deleted, you can safely knock out a broken component from its crosspin: just turn the parts with the rollers up and the metal will neatly run away the part from the cone.

Important! Carefully monitor not to apply mechanical damage to the front of the crossbar and ribs of stiffness.

• If the component has been dismantled, then further work will go like oil. Collect the chair, screwing the mechanism of swinging to the seat seat, make sure that everything matches its position.
• Now simply omit the cross on the wheels and remove the shipping cap from the gas cartridge. Insert the new component into the design, for the forgetting about the compliance of the details diameters.
• We wear a protective casing and the case into place. If all actions have been performed without errors, you can press the body to the surface of the housing and check the performance of all items.

Important! If any problems arose with a new element, that is, the likelihood of what you encountered a factory marriage. Before contacting the manufacturer, check the button fixation by the element with the lever. It is also not recommended to press the button if the component is in your hands.

Stock foot

Repair of chair on wheels - it is pretty simple procedure For those who have ever been dealing with similar designs. If you are a newcomer in this matter, we hope that this instruction helped you.

Independent and completely free repair of a computer chair, which consists in replacing the plastic sleeve holding a gaslift cylinder, on a wooden sleeve made with their own hands.

The other day I broke a homemade computer chair.

Although the chair is already becoming old (he is already about six years old), nevertheless, to this time, it served me and member of my family, quite properly. Especially since about once every six months, I carried out the prevention consisting in pulling up all the threaded elements, as well as the lubrication of the rubbing parts (first of all - the bearing at the end of the gas lift).

However, some time ago, I felt that the chair began to hang out and sway from side to side, and the further, the stronger.

After breaking it, I saw that the plastic sleeve, which stands at the top of the outer tube of the gaslift and serves to center and fix the cylinder of the Gazlift, severely crackled, and several pieces even fell off.

When I began to pull it out, some of the sleeve, which was directly inserted into outdoor pipe Gazlift, generally collapsed into pieces, so only the rim remained as a whole, that is, the uppermost part of this sleeve.

Naturally, I immediately began to look at the Internet, whether such bushings are sold among the spare parts for computer chairs. However, it turned out that such small parts Like sleeves, separately are not sold (at least, I have not found such anywhere).

Nevertheless, buying the Gazlift of the whole, I did not want, because, on my armchair, the gas lift is still quite good and without any complaints.

Therefore, I decided to make such a sleeve on my own.

To begin with, of course, I wanted to find some kind of similar plastic sleeve, but not finding such, I decided to make a bushing of wood. It is best for this. suitable wood Birch, it is strong enough and processed well.

However, the problem was that such a sleeve is a pronounced body rotation, so it is best to produce on a lathe.

I have turning machine No, but to use for this drill, it would also be problematic because the part is quite complex - it is necessary to process not only the outer surface of the workpiece, but also the inner (hollow of the sleeve).

As a result, I decided to go to another way and make almost the entire sleeve with a ring saw (or crowns) on a tree.

And here I must say that I was very lucky because measuring, inner diameter The tubes in which the sleeve is inserted (it is 48 mm.), as well as the outer diameter of the gaslift cylinder, which will be inserted into this sleeve (it is 28 mm.), I was able to pick up the ring saws, almost perfectly suitable for drank the specified diameters!

So, in order to make the mentioned sleeve, I needed the following accessories:

Materials and fasteners:

The segment of a thick, well-dried bitch from birch, with a diameter of 6-7 cm, and about 50 cm long.
- Four small screws 3.5x10 mm.

Basic tools:

Drawing and measurement tool (pencil, kitchen and caliper).
- Shilo.
- Manual wood saw.
- Electro-screw-screwdriver (better two electric drills).
- metal drill with a diameter of 4 mm.
- Ring saw on a wood diameter of 29 mm.
- Ring saw on a tree with a diameter of 51 mm.
- Pennic drill on a tree with a diameter of 25 mm.
- clamp.
- Sandpaper.

I must say that above I mentioned only the most basic tools, but in the process of work, it periodically had to use many other tools (for example, the chisels, a knife, a file, etc.), but I did not mention them, otherwise it turns out a huge List of tools.

Manufacturing process

So, at first, if necessary - we update the end of the birch billet, sculpting it with a small part of the saw. By the way, it can be done with an electroll bitch, but I specifically took a hand saw to once again Will get sophisticated because Frost on the street! : E113:

Then we postpone from the end of the workpiece, about 35 mm, (this is just the depth of the ring saw and the length of the lower part of our future sleeve) and we do in this place in the circumference, a depth of about 5-6 mm, a hand saw with a fine tooth.

After that, we place the center of the workpiece at the end, clamp its clamp and make it along the longitudinal axis of the workpiece, it was cut until it stops, with a ring saw with a diameter of 51 mm installed in a drill.

Now we also do it up to the stop, but already an annular saw with a diameter of 29 mm.

After that, insert the pericke flux to the drill with a diameter of 25 mm, and drill it excess wood from the internal propyl.

When wood is selected to a depth of two or three centimeters, you can again do cut the ring saw until it stops to deepen the inner hole.

Then we remove excess wood with perovy drill. And so do several times alternately until we have depth inner hole It will not reach 4.5-5 cm. By the way, it is better to use two drills for these operations (if possible) to rearrange the drills every time.

After the sleeve is formed by us, you can remove the clamp and make a finite refinement of the surface of the sleeve first with a knife and then sandpaper.

Now you can sprill the blank of the sleeve.

To give her a more accurate look, you can chop out excess wood from the top ledder of the bridge of the chisel.

Then we carry out the final finishing refinement with knife and emery paper.

And here our sleeve is ready finally!

Now it is necessary to make a small refinement of the tube of the computer chair, in which our sleeve will be inserted, namely, drill holes in it under the screws.

Therefore, the drill with a diameter of 4 mm, the four holes under the screws are drilled in the tube.

Then remove the chamfer, and at the same time the burrs from these holes with a drill of a larger diameter (8-9 mm).

Inside the tube, burcks remove with a round metal with a shallow notch.

Now you need to thoroughly clean the tube from the shallow metal chips and you can install our sleeve in it.

The sleeve gently clog the hammer with random blows.

And then wrap the screws into the prepared holes, for additional fastening of the sleeve.

Now you can collect a computer chair.

But before, it is necessary to smear well with a plastic lubricant, the thrust bearing.

And, of course, the inner surface of our sleeve.

Now, now, we finally collect the chair, that is, we dress the bearing on the gazlift, then we wear a pipe with a tube and a sleeve on a gaslift cylinder, install an outer washer and a fixing wash-latch.

And so it looks like our chair with a new wooden sleeve.

After testing the chair, it turned out that everything is functioning normally, the chair turns, the height of the lift of the chair, is regulated without problems, there are no special hoptes.

Although it must be said that theoretically, the wooden sleeve for strength does not particularly give the plastic. Therefore, I hope that it will work long enough.

The only thing in my opinion is that with this sleeve can happen - she can crack. But I think that in this case it will not lose its performance, and for its strengthening it will be possible to make it top Clamp or even just stronger wrap the tape.

Well, I'm all!
So far so far and reliable and durable homemade!

Most Russians B. home interior Often use an office chair or computer chair. Convenience this subject Provides the complexity of its device. If some mechanism fails, our compatriots will need to repair an office chair with their own hands, the video instruction of which can be found on the Internet.

It should be understood that cheap to buy office furniture In Moscow, you can in many stores. However, if for the company such costs are quickly paid off, and it is ready to change the broken chair for your employee, then for the usual population, such costs are inexperienced. For this reason, the Russians prefer to repair an office chair.

Complexity repair work Depends on breakage or damage. Leather chair during damage to the coating will require a blunt. Some cases may require even welding elements of this subject. Sometimes the owner will have to acquire a new spare part to the chair. In any embodiment, the price of a question on the independent restoration of the broken product is much less than the departure of the master to the house or buying a new chair.

Before starting repair work, experts recommend to explore the design of the office chair. You can do this on the Rio-Furniture website or other specialized resources. The main thing in this process is to follow the sequence of actions and accuracy when performing various operations. Having studied a schematic device of any chair, our compatriots will understand the principle of its assembly and will be able to repair almost any product.

The main components in office chairs are:

• cross;
• metal platform with height control lever;
• pneumopatron;
• armrests;
• adjustment adjustment of the backrest;
• rollers (wheels);
• back.

All items are mounted with screws with screws, therefore, it will take ordinary and cross-screwdriver to perform repair work.

The most often breaking the pneumopatron, so it is important to explore how to repair the gas lift of the office chair with your own hands. Structurally, this element is a two-flame system with air inside. If the office chair does not change its height, the pneumopatron should be replaced.

Also often requires replacing rollers. However, experts recommend changing all the wheels at once in order not to disrupt the horizontal level. If you need to change the cross, the owner of the chair may even think about the modernization of the existing product, turning it into a more comfortable piece of furniture.

Whatever the office chair has failed to replace the element is easy to find in stores that implement office furniture. Repair work do not take away a lot of time, but the restored stool will last for a long time. It is important only to choose the right parts for the model of the chair so that the additional openings should not be drilled.

IN modern office A variety of furniture is used, but in the first roles, of course, there are special chairs that provide maximum comfort when working on a computer. The office of the office chair involves the presence of the following main possibilities:

• Adjusting the height of the chair, which allows you to use this furniture to people of the most different growth.
• Adjustment of the head of the backrest of the chair - with any occupied posture, you can ensure availability reliable support For back.
• Free rotation of the chair around the vertical axis. This feature is useful for any form of office work.

Unfortunately, such chairs sometimes break down, due to some extent the complexity of the internal device. You can, of course, call into the office of the furniture repair masters, but in some cases it is quite realistic to carry out this repair yourself.

Main nodes and office chairs details

In order to better imagine a computer chair device, you can look at this scheme:

The appointment of such parts such as the base, rollers, seat, armrests and the back is quite obvious. The handle D is designed to change the tilt of the chair. Screw figured A allows you to adjust the height of the back and fix it.

Gas lift is the greatest interest. It is this detail in combination with a fixing screw figure in the opportunity to arbitrarily change the overall height of the chair. The name "Gazlift" gives a certain idea of \u200b\u200bthe principle of operation of this node. Internal organization Gazlifta can be seen in the following illustration:

The gas pressure in the cylinder is selected so that an empty chair with a rejected curly screw in will be pushed up, but if a person will sit in the chair of medium-sized body and weight, the seat will fall down. This makes it easy to adjust the landing height.

The main causes of breakdowns

Office chair can fail, or lose part of its functionality different reasons. Some of them, most common, can be listed in a small list:

• Systematic excess permissible load on the design of the chair.
• Sharp, "catastrophic" and significant largest exceeding the permissible load.
• Careliness made by assembling armchairs.
• External influence.

Most often, the chair comes into a faulty state on the first cause. This is partly due to the fact that the design office chairs Never differed considerable strength and rigidity. Such a harness and led to frequent breakdowns.

About what should not be done

Despite the abundance of parts, the device of the office chair can not be called some incomprehensible. But, despite this principled simplicity, some repair operations are better not even start.

For example, in the event that the Gazlift could not stand the gravity of the dying and "released gas", then repair it, or rather, no longer succeed. Such a chair is better to immediately attribute service center - They know exactly there how to fix the computer chair. In addition, there are also special equipment for repair work with a gas lift.

Do not advise any repair of the base, armrests, rollers and other small parts of the chair - they should not be repaired, but immediately change. The disturbed integrity of the design of each of these parts to restore would not work anyway. Actually, the repair of the chair and comes down in general, to replace the nodes failed. I must say, Gazlift - to such an extent "complex" item, which and change it as simple as armrests, will not work. Operation on the dismantling of the gas lift and the disconnection of its so-called piastra (the element of the seat with the seat) will require a lot of patience and accuracy in actions. By the way, often because of excess weight, it is most often broken by a pianzer, not a gas lift.

Instruments

Given the peculiarities of repairing an office chair, we can say that the only tool for repair work will most likely, a regular screwdriver. However, if it still wants to separate the Gazlift from Piastra and replace it, you will have to get a special hammer with a rubber "shock part"
