Mechanisms of transformation

The mechanism allows a foldout couch and write and, basically, that his schema defines the structure and design of furniture. There are many different mechanisms of transformation of furniture (over 15), but commonly used are: “French” camp, “book” or “click-klyak”, “accordion”, “roll” and “Dolphin”.

“French” camp.

The mechanism is most common (especially in foreign models of furniture). Allows you to use any, fantastic design, as in the classics and in modern. But does not provide a niche for laundry. It has four classes of performance: economic, napivortopedychnyy, orthopedic and “daily sleep.

Keeper class. As a “sleeper” is used polypropylene covering (similar to the Soviet clamshell with higher quality fabric material and springs that are not popping up and stretching) or metal mesh (similar to the Soviet iron beds with a metal grid, only the highest quality) plus a thin foam mattress. Have a good sleep on the couch so hard, but possible.

Napivortopedychnyy class – under the cloth puts a few extra slats. Lamella made of laminated veneer, which is attached by pressing curved. Because of its shape and material (for the slats plywood used birch or beech) lamel “works” as a flat spring. This, in principle, and orthopedic effect is achieved. The best (but expensive) are considered beech slats.

Orthopedic grade. The mechanism has 12-14 transverse slats. It is set just foam mattress (9 cm). Typically, for a standard mattress (and cheapest) brand foam (ST-2534). If you talk about what should be (theoretically) your mattress – it should be of high density foam, and stiffness. Ask the manufacturer (salon that sells ready made, do not be able) to replace the standard mattress vysokoschilnyy and hard. And suddenly he agree?

Movements of sleep daily “appeared recently, and despite the high price is a strong demand worldwide. Its main difference from the above-listed mechanisms – the presence of spring mattresses, 12-14 cm thick This mechanism can actually sleep and not only the guests … However, despite the presence of spring mattress, this mechanism (and all following) behind the normal bed.

“French” camp involves the use of the mechanism as a guest option. This furniture, which occasionally have guests sleep. It is not designed for daily use. If you plan to use for daily sleep sofa, note the class mechanism and the mattress should be (ideally) with vysokoelastychnoho foam, latex or spring unit.

“Book” or “click-klyak.

One of the easiest and reliable mechanisms. Allows you to place the bridge under the seat niche for laundry. The mechanism has no moving or those rotating parts, namely, they fail in the first place. Remember the old “good” Soviet sofas in which the mechanism of transformation was practically the only one? “Click-klyak, and a sofa into a bed. Very often, unfortunately, these sofas are pronounced only “click”, and “klyak” came from the second or third time. Despite the simplicity, quality mechanisms leave much to be desired. We have presented a reliable and market mechanisms for quality sofas type “book”, not only domestic but also overseas. However, domestic producers are practically not used the mechanism of transformation. Maybe because the mass production of low-quality upholstered furniture in the “good old days” forever repelled the buyer wishes to purchase “books”.

“Roll”.

One of the most common and reliable mechanisms. Sleeper “vykochuyetsya” from under the couch. This mechanism is important that the portion of the frame, which rides on top spot, was made of solid wood (pine in the squeeze roller groove). Better yet, if applied fully metal frame. Note the material from which produced commercials and on their diameter (larger – the better). Faulty or improperly installed can jam the mechanism. Note the smoothness of operation.

“Dolphin”.

This mechanism is used mainly for furniture corner models. Front put forward by “getting in the loop”, and draws on a booster seat, which is part of the berth. Case One of the most common and reliable mechanisms. Sleeper “vykochuyetsya” from under the couch.

“Dolphin”.

This mechanism is used mainly for furniture corner models. Front put forward by “getting in the loop”, and draws on a booster seat, which is part of the berth. Case linen hidden, usually not in the “Dolphin”, and the angular unit. Notice how easily you were able to uncover a sofa. A good mechanism allows it to do easily (or almost no effort).

“Accordion”.

Accordion he called in Europe. We have it – harmonica. In this design sofa forward the principle of “bunching”.
