The sons' folding sofas began to unfold poorly, the mechanism is jamming. How can we repair our folding sofas ourselves?
Of course, you can fix the sofa yourself, but you will need simple tools that are usually present in every home. First, you will need to remove the sofa transformation mechanism so that it is convenient to work with it. From the description of the breakdown, I conclude that, most likely, due to old age, the movable retainer was deformed - this is the most unreliable part in this mechanism.
It is important to consider what we will repair, the mechanism itself, or, for example, change the springs of the sofa, or change the upholstery, and so on.
As you can see, the frame of the mechanism is assembled on rivets, and if the problem is here, then the mechanism simply changes to a new one (similar, they are on sale).
In principle, it is possible to replace the rivets, you can even replace the rivets with a flat head bolt, but look at the place.
If we change the rivets, they are pre-drilled, in order to install new ones, you need a tool, for example, a rivet gun (it's easier to change bolts)
If the fastenings of the mechanism to the sofa are loose, then you can either tighten or remove the mechanism and “cure” the loose area.
For example, the hole has become larger in diameter from the desired one.
Drive a dowel into it and then install the mechanism in the reverse order.
To get to the mechanism, you need to remove the two sidewalls of the sofa (armrests), they are attached in different ways, but as a rule, the fastening is bolted.
If we mean repairs to replace the upholstery of the sofa, the sofa is completely disassembled and the sides and back wall.
Almost every home has upholstered furniture such as a sofa. Many are accustomed to using it as a sleeping place and very often lay it out and assemble it. What to do if the mechanism of the sofa is damaged and it ceases to perform the functions you are used to? Do not despair, repairing the Eurobook sofa is possible even at home. The main thing is to stock up on the necessary tools, as well as patience.
Repair of the sofa mechanism most often becomes necessary when the latch fails. This happens because of old age, frequent and heavy workloads, as well as manufacturing defects. You can find the last reason almost immediately, because a faulty mechanism will be difficult to decompose. In this situation, you can ask the store to replace the model or the mechanism itself. Nobody will restore the rest of the breakdowns and you will have to cope with the problem yourself.
If you do not know how to repair a sofa with a similar problem, then you can see photo and video information on the Internet. They should unfold easily, and if problems arise, they need to be eliminated immediately, otherwise then he may completely jam. To begin with, the sofa book needs to be disassembled in order to reach the mechanism itself.
Usually it is located on the side, so there should be no problems, basically removing the armrests is enough.
Then the scale of the problem should be assessed. The mechanisms that can break themselves are very simple, and if a problem arises, it immediately becomes visible even to an inexperienced person.
The moving parts must be tightly connected to each other. If one of them dangles, then this is no longer correct and perhaps it is because of her that the sofa does not unfold well.
It is also imperative to check the springs.Over time, they weaken and sometimes do not hold the back so confidently. And of course, from use they can simply loosen, a foreign object and so on can get into them. If the problem is just this, then you don't need to disassemble anything, eliminate the trouble and use your favorite sofa again.
All that needs to be replaced, you can easily find in any hardware store. If you decide to carry out the procedure yourself, then experts advise you to immediately completely change the mechanism, and not its individual parts. This will avoid further breakdowns and increase the service life of upholstered furniture for a fairly long period. In general, a complete replacement will take place much faster than a partial one.

If your sofa does not fold out, and you don’t know what to do, then it’s better to seek help from specialists. This is especially true for girls who may find it difficult to disassemble the sofa. To carry out the work, a man's hand is required, and sometimes the help of a friend. The sofas themselves are very massive and it is not always convenient to dismantle them alone. But, it is worth noting that the renovated sofa will serve you for many years to come. And on all this you will spend rather small amounts of money in comparison with if you buy a new model.
DIY upholstered furniture repair with before and after photos
In the conditions of using movable transformation mechanisms in sofas, their malfunctions occur most often. But this is not the only possible problem: the upholstery can be damaged by pets, the sofa sags over time, loose fasteners cause play in individual parts, and so on.
The main components of the sofa
And in order to understand how to repair a sofa, you need to understand its main units.
Sofa frame - main supporting structure
Sofa armrests with opening top
Variety of sofa filler options
Spring block for sofa
Upholstery fabric for sofa upholstery
This is how the transformation mechanism of the sofa looks like.
Wooden sofa frame
If there are problems with the body or armrests, the sofa needs to be repaired urgently to avoid further operational problems. When fixing broken wooden parts, we need the following materials and tools.
Joiner's furniture glue.
If necessary, paint and varnish.
Screed or profile.
Self-tapping screws and screwdriver.
A set of hexagons and furniture screws for them.
Emery cloth.
Clamps.
Drill and drill set.
An approximate set of tools for repairing and restoring a sofa
In the case of a chipped part of the armrest, it is worth collecting the fragments. Do not clean the chip under any circumstances!
Apply a layer of wood glue.
Attach the shard to the main part and secure with clamps through the bars.
Let the glue dry. On average 1 day.
Secure with a tie and self-tapping screws (not from the front part).
Sand the glued area with emery and sandpaper.
Apply paint and varnish.
In the repair of the main frame, it is better to replace the load-bearing boards with new ones, but you can also put support in non-critical cases. For this you need:
disassemble the sofa to access faults;
align the faulty plate and glue it with glue;
install bars (ties) on the back side for additional structural rigidity;
assemble the sofa.

Mix glue with sawdust for better adhesion and quick drying.
This mixture can also be used to fill holes for screws and bolts.
Pet owners know firsthand about coating problems. Also, replacement is carried out after severe contamination and obsolescence of the skin. Only the complexity of the conduct depends on the material, and not the process itself. But nevertheless, it is better to entrust the replacement of leather and leatherette to professionals.
Disassembled sofa for renovation work
Required tools and materials:
Construction stapler and staples.
Sewing kit.
Screwdriver and screwdriver.
Textile. Flock, velor, jacquard, chenille or tapestry are commonly used.
Flock is a soft, durable, durable material that is pleasant to the touch
Beautiful and expensive fabric for constriction - tapestry
Carefully disassemble the sofa into its component parts.
Remove the trim without damaging the fabric. It will serve as a template.
Cut out a new canvas, taking into account the peculiarities of the relief.
Stretch starting from the front, fixing with staples.
Repeat the procedure for all trimmed elements.

The loss of elasticity and resilience is associated either with the spring block or with the filler. Also, the replacement of the filler must be carried out in connection with the appearance of unpleasant odors and the breakthrough of the upholstery from the inside.
Construction stapler and staples.
Screwdriver and screwdriver.
Filler.
Carefully disassemble the sofa into its component parts.
Remove the trim carefully.
Take out the old foam.
Install a new one with a total thickness of 35-40 mm.
Secure the filler with glue or staples.
Change the filler along with the upholstery. The total expenses for independent work will not exceed 3000 rubles.

Restoration of the spring block
A serviceable spring block determines the absence of subsidence of the sofa and its convenience. It consists of zigzag springs and is fastened to the body in the form of arc-shaped brackets.
Materials and tools for repair.
Screwdriver and screwdriver.
Construction stapler and staples.
Disassemble the sofa into elements.
Detach the upholstery carefully.
Remove filler and backing.
Loosen the tension on the defective spring and replace it.
Reassemble in reverse order.
If many springs are malfunctioning, it is better to replace it with a whole block.
Replacing the elastic bands in the back is similar.
Furniture manufacturers are increasingly moving away from springs in favor of lamellas. The change process is the same.
Possible options for transforming sofas
A high-quality mechanism most often determines the cost of a sofa, since moving parts break faster. There are several types associated with the principle of operation. Each of them requires its own maintenance and problem fixing.
Set of wrenches.
Screwdriver and screwdrivers.
Machine oil or other lubricant.
Stapler and staples.
Drill and drill set.
Diagram of the transformation mechanism of the "Roll-out" sofa
The most common mechanism. The popularity is associated with the simplicity and low cost of execution. It was named so because of the principle of rolling out the section for the "bed" position. It also consists of rollers on an additional section, a slide with a fixing bracket on the body. There is also a lifting mechanism or an additional leg. Common problems are braking and squeaking when rolling out. It is solved by replacing the rollers and sleds. There is also a lack of complete fixation in the "bed" position. In this case, repair of the retaining bracket is required.
Diagram of the transformation mechanism of the "Book" sofa
It has been known since Soviet times and is already morally obsolete. In this regard, it is difficult to find accessories for the device. The sofa uses the front of the backrest as an additional section. The transformation takes place by folding the back and sitting together, removing the roller from the end position, rolling the roller and decomposing the sections. The most common problem is the inability to unfold or fold the sofa. In this case, do not use force. It is “treated” by disassembling the sofa, cleaning the guides, removing the tension from the fixing spring, lubricating the axle and fixing the jam or replacing the roller. In case of multiple problems with the mechanism, a complete replacement of the block is preferable.
The new variations use a rocker piece with springs. It is more reliable. But in the event of a malfunction, a complete change is required.
The scheme of the transformation mechanism of the sofa "Click-Klyak"
The most modern type for serial models of upholstered furniture.Has three positions. "Click Klyak" allows, in addition to the seat, to use the backrest and armrests as a sleeping surface. An interesting name is associated with the sound of transformation. Outwardly it looks like a book mechanism. However, it uses a special folding mechanism without rollers. Since the perfect fit of all moving parts of the device cannot be done at home, it is better to change the entire unit. To do this, it is necessary to disassemble the casing and filling and fix the breakage.
Diagram of the transformation mechanism of the sofa "Accordion"
Has three positions. Unfolding and fixing occurs due to movable axles and locks. For disassembly you only need a 10 spanner. The locks themselves look like a clamp without a tightening bolt. Frequent problems are similar to those of a sofa-book. All elements must be lubricated periodically.
DIY sofa repair process
Do not try to replace one mechanism with a completely different one. The use of different principles of work determines not only the difference in components, but also in the purpose of the elements.
Chipboard is more difficult to restore than wood.
If the support metal is bent, replace it immediately and do not try to straighten it. The structure of the metal will not withstand long loads and will deform again.
Frame play leads to breakage not only of the wooden parts, but also of the guide rollers. The friction generated also harms the upholstery.
Apply grease only to cleaned surfaces.
Do not overtighten the fasteners.
Hex keys must be of good quality. "Licked" edges will stop work for a long time.
WD-40 can be used to remove rust from moving parts.
Do not neglect installing washers on bolts and axles.
It is not necessary to make wood slabs or cladding yourself. It can be ordered in a furniture showroom.
The "licked" heads of the fasteners should not be rocked or tried to pull out the bolt. It is better to cut it off with a sheet of metal.
Monitor the condition of the pallet. This part of the frame is load-bearing and undergoes high loads.
Call a partner for all repairs. This will make your work easier and safer.

A sudden breakdown of the sofa transformation mechanisms can cause a lot of trouble for the owner. Squeaks, distortions, the inability to unfold and fold the sofa, sleep disturbances constantly remind us of the urgency of urgent repairs. You can, of course, contact the master and call a professional to fix everything, but often these breakdowns of the transformation of sofas can be corrected with your own hands. We will consider the main types of breakdowns and options for their solution in this article.
Today, furniture production has a large number of types and types of mechanisms. The photo below shows only some of them (the most common):
The click-gag mechanism has three positions, one reclining and two for sitting. It is usually installed on modern lamella-type models.
Meralax is one of the reliable French clamshell layout mechanisms. Has an orthopedic effect in two versions - lamellar and metal weaving.
The dolphin mechanism is exactly the option that combines compactness and convenience. A seat is attached to the side parts of the frame, pulling the mechanism out of the niche "towards itself" to the upper horizontal position for the transverse bar and we get a full-fledged berth.
This is the simplest of all existing mechanisms. In high-quality performance, it is stable and durable, but, as a rule, the metal from which it is made leaves much to be desired.
Mechanism "accordion" - one of the most popular mechanisms for transforming sofas, has three positions of the layout.
One part is motionless, the other two have movable parts fixed with locks.
Now it is installed mainly on modern models of upholstered furniture.
The most common mechanism is installed on a sofa bed. It is quite simple to lay out and has a number of advantages over other models. The whole structure is made of thick metal and quality rivets.
You can also familiarize yourself with other types of sofa transformation mechanisms in the article Overview of sofa transformation mechanisms.
The models shown in the photo have their own individual characteristics. Here, not only the angle of inclination plays a role, affecting the lowering and lifting of the weight, but also the material from which they are made.
Many manufacturers use thin-walled metal and very low quality rivets for these mechanisms, because of this, furniture becomes unusable in a very short time.
If it is not possible to replace the broken mechanisms with new ones, you can make repairs at home. Of course, it is not always possible to do everything as it should, but it is quite possible to extend and give a "second" life to furniture.
So, what in these mechanisms can be repaired at home:
Replace battens, nets and lamellas.
Replace springs, rivets.
Strengthen the frame by welding.
Replace rollers.
Before proceeding with the repair, you need to determine the extent and cause of the breakdown. As a rule, it is mainly the rivets of the guide bar that are bolted to the frame of the sofa that break here. They fly out completely or a depletion appears, leading to an increase in the gaps.
For work we need tools:
Drill or screwdriver
Rivets
Hammer
Anvil or any other massive stand
It is necessary to rigidly fix the mechanism on the surface of the table, for example, with the help of clamps. We drill a broken rivet with a drill, starting with a small drill and gradually moving to the desired size.
To select the required drill diameter, measure the riveting size and thickness with a vernier caliper. We insert into the hole, with the hat down, and the part that will be riveted should look up.
If it is not possible to repair the mechanism with rivets, the bar can be fixed with a bolt and nut.
Here it is very important to choose the right length so that the bolt does not rest on the frame from the inside, because it will not be very convenient to cut it after installation!
This design has a number of small details that affect the correct layout of the sofa. Naturally, the repair will have its own difficulties, but with the right approach, this issue can also be resolved.
The figure shows the main elements of the "accordion" (its most vulnerable parts), since they are the ones that carry the main load.
After the expiration of the operating time, some of them require, at best, repair, and at worst - replacement.
The rollers must be replaced ... At home, you can change the polyurethane base of the wheel by choosing the desired size (height). Having drilled out the mounting axle, it can be replaced with a regular bolt with two nuts for better wheel fixation.
Due to their rigidity and strength, beech lamellas are almost impossible to break, although there are exceptions to the rule. Basically, the fasteners that "hold" the lamella break.
The photo shows that the lamella insert is attached to the metal frame with rivets.
In specialized stores, almost all furniture fittings are sold, including the "pockets" we need.
To replace them, we need a drill, with which we need to drill out the rivets. We check their width and thickness so that there are no unnecessary gaps.
Riveting can be done with smaller and larger hammers or with a riveting tool.
But the best option for installing the lamella holder is a regular bolt and nut.
Today the mechanisms "Click Klyak" in terms of the quality of operation leave much to be desired.Manufacturers do not pay much attention to strength, relying on a large area of the frame (the larger the area, the more stable the product).
The body bends in places of localization of weight, since it is made of sheet iron, from this the transformation lock itself breaks.
Making repairs at home can be very problematic; only a complete replacement is possible.
In order for the mechanism to serve for a long time, it is necessary to lubricate the rubbing joints in time.
They are shown with arrows in the figure below.
A common cause of breakdown and rapid failure of the mechanism is the fastening bolts tightened at the wrong time between the wooden frame and the mechanism.
During operation, large gaps appear, which lead to distortions and depletion.
The pull-out mechanism of the sofa is one of the most durable and reliable structures, but, as it turned out, it can become unusable in a very short time.
The reason for this fragility is in poor-quality layout elements, in particular, in the rollers. For reliable disassembly and assembly of the mechanism, the rollers must rotate easily and slide freely over the surface.

In this article, only the main reasons and options for breakdowns of the transformation mechanisms of sofas were described, which, without special preparation, can be performed by almost any owner.
You should always remember what to produce overhaul only a trained specialist with the necessary set of tools will be able to lay out the sofa. He will always be able to accurately determine and eliminate the cause of the breakdown at a quality level.
Without proper experience, such a repair can lead to even greater malfunctions, therefore, if a problem is found, carefully study the cause of the breakdown of your favorite sofa, evaluate the complexity of the structure and your strength, as well as if you still decide to repair the mechanisms of the sofa with your own hands , be very responsible about the process itself.
A sofa has become a completely ordinary element of the room, and this is quite natural, because you can sit on it, sleep, spend evenings with friends and so on. But what if you broke down? What to do if you need to repair the mechanism of the "book" sofa with your own hands? Do not worry, there is a solution, since the repair is quite simple.
Before proceeding with the repair, let's look at the details of the sofa, as well as their purpose. The sofa consists of the following elements:
The armrest can be made of wood, MDF, chipboard, metal, it can be soft.
Upholstery leather or fabric - there is a wide variety of upholstery materials, both natural and synthetic.
A layer of batting or padding polyester.
Foam rubber in sufficiently high-quality sofas is used for furniture, with a density of at least 35 mm.
Polyurethane foam pads are not used in all models. It serves for additional cushioning, as well as distribution of weight, thanks to such inserts, the surface of the sofa shows orthopedic properties.
Spring block, which is the main shock-absorbing element of the structure.
Felt or burlap prevents unpleasant sounds from rubbing plywood against metal.
Fiberboard serves as the basis for the sofa mattress.
The frame of the sofa may well be made of wood, chipboard or metal.
The roller rail can be located on the bottom of the bed box and be either metal or wood.
Niche or box for bedding.
Important! Features and designs may vary slightly, but these elements will be in place. Therefore, when you take apart your sofa, you will know the purpose of one or another of its parts.
If the transformation mechanism is defective and needs to be replaced, get the type that you originally had.Other types of mechanisms are not interchangeable because they simply will not work.
To repair the mechanism of the "book" sofa with your own hands, you need to disassemble the furniture:
Dismantling the sofa begins directly with the armrests. In certain models, they are combined with the legs, while in others, they are separate from the legs. In the first case, place a wooden bar under the base of the sofa so that it hangs from one end. This way you do not have to tighten the bolts of the other side elements. The sides are attached with two bolts. To get to them, you need to raise the sofa seat or pull out the retractable part - it depends on the design of the sofa.
As soon as you dealt with the armrests, remove the transformation mechanism. To do this, use a screwdriver or screwdriver, drill. It is attached with one part to the frame itself, and the other directly to the seat and back. In an ordinary sofa-book it will not be difficult - you just need to turn the seat, as well as the backrest with the soft part directly to the floor. The access to the mechanism is completely freed.
Important! In the course of work, we take pictures or write down which mechanism, in which place it was.
To repair the transformation mechanism, you will need:
Flat and Phillips screwdrivers;
Pliers;
Set of open-end wrenches, sizes 8/10 and 12/14;
Set of staples and stapler 10 and 16 mm;
PVA or carpentry glue;
Scissors;
Hammer, electrician's knife;
Self-tapping screws 35 - 45 mm;
If you have a drill or screwdriver, put it in sight.
In order to repair the mechanism of the sofa, remove it and determine further the level of damage:
If the fittings are intact, it is likely that it will be enough to lubricate the units with machine oil and develop them.
You can replace the spring if it is damaged. If it is overstretched, try shortening it a little.
The transformation mechanism is deformed or burst directly - get an identical one and install it.

With the repair of the frame, everything will be much more complicated, but everyone can do it. If there are broken or cracked frame elements, they must be replaced:
To do this, measure their exact parameters, sketch their appearance and, taking the money, go to the nearest construction hypermarket or carpentry shop. There is a department that will cut the frame element you need. Replace element, screw and glue other attachment points. When doing this, pay special attention to the plywood that is under the spring block.
If any part of the frame “walks”, fix it with self-tapping screws instead of nails and glue it with PVA glue.
If there is an unpleasant creak when you sit on the sofa disappears, collect and use for your own pleasure.

We hope that with the help of our advice, do-it-yourself repair of the "book" sofa mechanism will be feasible for you, and your furniture will serve for a long time.
Almost every person in his life is faced with such a problem as a broken sofa that does not fold out. There are different options for breakdowns, then a description of breakdowns and ways to eliminate them will go.
The sofa seat collapsed.
If the seat of the sofa has a sagging appearance and has lost its original shape, then this indicates that the inner filler has become unusable. What kind of inner filler can be in the sofa - it can be foam rubber (as the most common), a spring block, and a broken sofa frame can also serve as the reason for the failure (this is what the foam rubber or spring block is attached to)
To find out the specific cause of the breakdown, it is necessary to detach the sofa trim from the frame and look inside. And what do we see there? You need to carefully analyze what caused the failure of your sofa.If this is squeezed foam rubber, then everything is simple here, measure the dimensions, thickness, length, width, and at any construction market or in a hardware store, buy the foam rubber you need and replace it.
If the owner of the sofa is overweight, then the reason for the depression of the sofa can be the spring block, which is deformed and the springs broke from the weight of its owner. To eliminate such a breakdown, you need to purchase a new spring block and fix it in the attachment points.
A broken frame is also a common breakdown of a sofa failure. It can be a broken beam, hardboard or plywood, which, due to weight or due to time, broke and fell through. How to fix such breakdowns is not as difficult as you might think. To do this, again, disassemble the sofa by separating the fabric from the frame, then remove the spring block, foam rubber and get to the frame. If the hardboard or plywood flooring is broken, then measure the width and length, purchase the required material in the construction market and fix a new piece of plywood with screws and glue. The simplest rule in furniture repair is that you don't have to invent anything, just change old parts for new ones.
If the transformation mechanism does not work, you can simply lubricate it with lubricating oil, then fold and unfold the sofa several times.
If your sofa won't fold out or fold.
The most common cause of such a breakdown may be broken transformation mechanisms. What to do if a similar problem occurs. The simplest thing that can happen is the working out of the metal of the mechanism; household lubricating oil or machine oil will help to eliminate such a breakdown. Just generously lubricate the friction points of the mechanisms and everything should fold and unfold. If it did not work out, then the second method is to replace the mechanisms with new ones, for this it is necessary to purchase similar transformation mechanisms and replace them. There is also such a breakdown when a break occurs at the points of attachment of the mechanism to the frame, that is, the attachment points (timber) breaks from the constant pushing of the sofa. the sofa is ready for use. The most important thing in sofa repair is to replace broken parts with new ones and that's it. There is nothing supernatural and complicated in any sofa, every person who has hands and mind in harmony can easily repair any furniture.
If the sofa battens are broken, you can simply swap them or glue them with PVA glue, holding them with clamps.
with movable armrests
with movable armrests
The sofa book "Click-Klyak", also known as "Click-Klak", consists of two identical sectional halves, a mattress, a cover, a folding mechanism and a linen compartment. There may be options with or without armrests. And also with side movable sections in the form of armrests that can be raised and lowered. Has three positions: "lying", "relax" and "sitting". The mattress in the Klik-Klyak sofa is often completed with a dependent spring block + foam rubber (PPU). Less often, only foam rubber - at the request of the buyer.
The cover is made of various materials of different categories with a synthetic winterizer backing. Like the mattress, the cover is attached to the frame with Velcro. It can be removed and washed. Unfortunately, a 5kg washing machine does not fit. The metal frame (section) consists of a shaped tube 20 * 30 or 30 * 30 mm with attached wooden battens (lamellas) using plastic latoderazers.
The sofa Klik-Klyak book is easy to use, but requires careful handling when folding and unfolding. To prepare it for the night - it is enough to raise the seat up to the characteristic clicks, then, holding the seat with your hands, lower it - and the sofa is unfolded. It is convenient when the room has an elongated shape. It must be remembered: do not allow "point" loads on the seats of the sofa. Otherwise, lamellae, lath holders may break.
With the daily use of the sofa, after about 5-7 years, the folding mechanism comes out: the teeth are erased, the riveted joints are loosened. Sometimes the rods bend in the mechanism. Unfortunately, when selling a sofa, sellers do not notify you where and how to lubricate the mechanism, how to avoid applying excessive force on the sofa when folding.
The master arrives in a two hour time frame. The repair of the sofa book itself at your home will take no more than 1 hour. All types of locks, rollers and other consumables are always available. At the end of the work, he writes out a receipt, which indicates a guarantee of 3 months.

Enjoying the comfort and convenience of the purchased clamshell, thoughts of breakage are far away. But, unfortunately, sometimes you have to get into trouble from real chagrin due to a broken clamshell.
Of course, depending on the nature of the breakdown, you can not resort to the help of specialists and try to fix the malfunction yourself. If, for example, we are talking about replacing armor and plastic plate holders. If the breakdown is more serious - a break in the awning, deflection of the frame folding units, etc., then in this case the entire structure must be replaced.
It is almost always easier to replace the entire clamshell!
We recommend using the services of our specialists. The master can be called at home by phone or through the feedback form. He will come quickly and help with the repairs. Our specialists travel to Moscow and the Moscow region.
A sofa is surely present in every home. Or almost everyone. And it happens that he suddenly starts to be capricious. It does not fold out, then it does not fold. We are talking about a good old couch-type couch.
Transformation mechanism. The most common cause of this harmful behavior is a malfunctioning transformation mechanism. This uncomplicated device has only one unreliable part: a movable retainer. It is he who allows the sofa to turn into a bed and back, and it is this retainer that wears out quickly.
Removing the spring. With a little skill in plumbing and a few simple tools, you can replace this retainer and restore the sofa to normal operation. First, remove the spring with pliers. At the same time, it is important not to release it, otherwise it will fly away in an unknown direction. If you are not sure, it is better to tie it first with a strong thread.
Removing the spring driver. The leash, to which the spring was attached, is rigidly fixed to the retainer pin with a rivet. We act uncomplicatedly, in the forehead: we just cut off the riveted part with a hacksaw for metal and ...
Disassembled retainer.… With the help of a chisel we release the leash. The tip of the self-tapping screw points to the worn surface of the pin, which is why the sofa stopped working normally.
Pick up the bolt. How can I replace this pin now? In my junk in the coveted corner, I found an old rusty bolt of 8, 15 millimeters at the head of which the threads remained undercut. Just what you need. I cut off the threaded part and get an almost finished pin.
Clamp the bolt in a vise.
Almost, because you still need to cut out the seat for the leash with a file. To do this, I clamp the head of the bolt in a vice so that it can be done more accurately with a file. Distance - 10 mm from the head.
The file is in business. File queue.
Finished pin.
Less than ten minutes from the start, the pin is ready to re-attach to the leash.
Assembling the retainer.
If so, a few light, accurate hammer blows, and you're done. It remains to put the spring in place ...
The mechanism is ready for operation. ... and be convinced of the flawless operation of the refurbished sofa transformation mechanism. Will last at least the same amount.
