Sofa mechanism accordion DIY repair

Today we are going to repair the folding / unfolding mechanism of the sofa. This breakdown occurred because the movable joints of this mechanism were out of order. This connection is a bushing with an ordinary washer, here it is riveted, tensioned by a spring.

In the second part, as you can see, he is no longer there.

That is why the sofa has stopped folding / unfolding with us. Well, this is all we are going to change now. To begin with, we will analyze this as you can see. It is quite easy to understand, because it is worn out.

Remove the tensioned spring and move on to a new set.

So, here we have an old set: bushing, spring, washer. As you can see, the washer is already worn out. The second washer was lost, when the mechanism flew out, it was lost.

And we will use these springs in a new set.

Now let's get down to assembly. So, we put this tensioner in the form of a spring and a washer on the bolt. And we put it all into the mechanism. Where it was originally.

Insert, don't forget about the washer. Tighten slightly with a nut. And we will definitely use a locknut. So that in the process of using it all this again does not start to fall apart.

It is advisable to tighten all this up. So that the locknut plays its role with us.

It drags on rather quickly.

On the right side, I installed everything a long time ago. You see, the spring is pulling and pulling this moving part.

And let's test it now. This is how the sofa folds up. And let's decompose it again. And our sofa can be easily expanded. So, we have repaired the mechanism. Everything works for us.

The accordion sofa is the most common type of upholstered furniture. Consists of three sections. Has only two positions: "lying" and "sitting". The inner filling consists of a spring block attached to a wooden frame + polyurethane foam (foam rubber). It also occurs - only foam rubber + plywood frame. The cover is attached to a wooden frame with metal staples and cannot be removed simply by hand.

It is easy to use and does not require constant maintenance. To prepare it for an overnight stay - just pull the "foot" seat towards you and hold the sections with your hands, then you need to "bend" the leg section to a characteristic click and lower it - the sofa is unfolded. To fold the sofa - it is necessary to lift the “leg” section up until a characteristic click, holding the seat with your hands, with forward movements downward, lower the section - and the sofa is assembled. It is convenient when the room is square.

Most often, folding mechanisms break down in accordion sofas. Unfortunately, when selling a sofa, the sellers do not notify you that it is necessary to lubricate the folding mechanism, and after 5-7 years of daily use, there are seizures in the friction points of the mating parts, jamming of the locking pin in the mechanism. If, after lubricating the rubbing surfaces in the folding mechanism, the locking pin does not start to jump, you will need to replace both sofa mechanisms with new ones. If you make too much effort in an attempt to fold an accordion sofa with a jammed mechanism, it can lead either to deformation of the mechanism itself, or to breakage of the wooden frame of the sofa.

Rollers break a little less often. This part suffers from excessive loads: during movement it encounters obstacles: the edge of the carpet, debris, overloading with heavy objects in the laundry compartment drawer. A broken roller can ruin the flooring and complicate the folding and unfolding of the accordion sofa.This breakage will also lead to deformation of the folding mechanism during assembly. There is also a high probability of breakage of the wooden frame elements.

We remind you: in order to preserve the working capacity of the folding mechanism for a long time, it is necessary to lubricate with aerosol grease in the area of ​​the retaining pin and the spring twice a year (in spring and autumn).

An attempt to make a do-it-yourself sofa repair can not always be crowned with success.

When choosing upholstered furniture, we are guided by different principles. Someone needs a large sofa complex for the living room, someone is looking for a convenient option for a small apartment. Modern models of folding furniture are quite diverse. But, the classic sofa system with accordion mechanism remains relevant and one of the most demanded on the market.

A fold-out sofa is quite a practical thing. When assembled, it takes up a minimum of space in the interior, and when unfolded it has all the advantages of a full-fledged berth. The accordion model is extremely easy to use. The three-stage layout is so elementary that it is even accessible to children. The swivel mechanism of the accordion sofa unfolds by simply lifting and pulling the canvas forward.

The design has three parts. These are blocks connected in series. The first two make up a sleeping place, which, when folded down, turns into a sofa back. The third part, when folded, is a seat, and when unfolded, it complements the length of the bed. The total length can be about 2 meters, which allows people with tall stature to fit comfortably on such a sofa bed. Reviews about the accordion mechanism for the sofa are different, and they depend on the preferences of the buyers.
