Repair of the vykatny mechanism of a sofa

Scheme of the transformation mechanism of the sofa “Vykatnaya”

The most common mechanism. Popularity is associated with simplicity and cheap execution. It is named so because of the principle of rolling out the section for the “bed” position. It consists of rollers on an additional section, a sled with a fixing bracket on the body. There is also a lifting mechanism or an additional leg. Frequent problems - braking and creaking when rolling out. It is solved by replacing the rollers and skids. Lack of full fixation in the “bed” position also happens. In this case repair of the fixing bracket is required.

Repair mechanism "sofa-books"

Scheme of the transformation mechanism of the sofa “Book”

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 side of the backrest as an extra section. Transformation occurs by folding the back and seat together, removing the roller from the extreme position, rolling the roller and decomposing the sections. The most frequent problems - the inability to expand or fold the sofa. In this case, do not use force. It is “treated” by disassembling the sofa, cleaning the guides, removing the tension of the fixing spring, lubricating the axle and correcting the jamming or replacing the roller. In case of several problems with the mechanism, full replacement of the block is preferable.

The new variations use a rocking part with springs. It is more reliable. But in the event of a malfunction, a complete change is required.

The most modern type for serial models of upholstered furniture. It has three positions. "Click Klyak" allows in addition to the seat to use as a sleeping surface backrest and armrests. An interesting name is associated with the sound of transformation. Externally similar to the mechanism of the book. However, it uses a special folding mechanism without rollers. Since the ideal fit of all moving parts of the device cannot be done at home, it is better to change the unit as a whole. To do this, it is necessary to disassemble the casing and filling and fix the damage.

It has three positions. Unfolding and fixing occurs due to movable axes and locks. For disassembly, you will only need a wrench for 10. The locks themselves resemble clamps without a bolt. Frequent problems are similar to sofa book problems. It is necessary to lubricate all elements periodically.

How to repair a sofa? Some tips

The process of repairing the sofa do it yourself

• 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 appointment of elements.
• Chipboard is more difficult to restore in comparison with wood.
• If the supporting metal element is bent, immediately change it and do not try to straighten it. The metal structure will not withstand long loads and is again deformed.
• Backlash of the frame leads to breakage not only of the wooden parts, but also of the rollers, the guides. Also created friction harms upholstery.
• Lubricant applied only to cleaned surfaces.
• Do not overtighten fasteners.
• Hex keys must be of high quality. The “licked” edges will stop work for a long time.
• You can use WD-40 to remove rust from moving parts.
• Do not neglect the installation of washers on the bolts and axles.
• It is not necessary to make wood slabs or lining yourself. It can be ordered in the furniture salon.
• "Licked" fastener caps should not be swinging and trying to pull the bolt. It is better to cut it off on metal.
• Monitor the condition of the pallet. This part of the frame is load-bearing and under heavy loads.
• For all types of repair call partner. This will simplify and secure the work.
