WELL, JUST VERY FLAT

Indeed, the proposed chair for the hallway is not just folding, but almost entirely flat, as folded, becomes almost equal to the thickness of the four panels, from which his legs (or rather — bearing panels). This is achieved in that all the components of the chair are interconnected is not a traditional fasteners. a hinge node-based piano loops.

 

The structure itself is extremely simple and available to play any home master. Moreover, no special tool, PI scarce materials do not need to have a handsaw, screwdriver, drill and trimming of thick plywood or chipboard.

 

The device and principle of folding

 

Outwardly is the most common small chair, sitting on which is very convenient to change the shoes, tying your shoes or clean shoes. And the fact that he is able to emerge, at first vzgyad not very noticeable. Moreover, under the seat visible not traditional legs, but how would a solid backrest.

 

Just looking closer, you notice that its flat seat and the sidewall beneath it consist of two halves. It turns out to be. the secret of folding: pulling the seat up and at the same time pushing the sides inward will be able to easily turn the chair in a flat pack.

Found that the two halves of the seat are connected together using piano hinges Are the same hinges fasten them with the front and rear panels Tselikov, acting as legs. The supporting function is performed by and connected with the latter (also with piano hinges) halves of the side panels having at the junction between them again at the piano loop.

 

Fabrication and finishing

 

All the main parts — the seat cover. sidewalls, the front and rear support panel are cut, as already mentioned, from plywood to a thickness of 7 — 12 mm or chipboard. All edges are carefully processed with sandpaper, first large, then smaller abrasive grain.

 

To all parts of the chair have been decomposed properly, it is very important to appropriately arrange the connecting loops (see Fig.). They are fastened by small screws, which should neverlet bore holes are smaller than theirs, diameter, and the screws during Assembly to lubricate the glue (carpenter’s, PVA).

 

 

 

On the panels of the seat are the vents and cut notched slits for fingers. For formation of cracks at their proposed contour tight drilled a series of holes, thin walls between which then cracked with a chisel or screwdriver, and the resulting shaped hole by gently handled bastard file and coarse sandpaper.

 

Arcuate cuts on the supporting panels of any shape and for simplicity they can be rectangular.

All blanks are stripped off and polished with sandpaper. Then covered with a stain to accentuate the texture and grain {if a piece of plywood) and again carefully polished. Now is applied in several layers of a furniture varnish with intermediate drying and sanding with fine sandpaper, the Final operation is polishing.

 

If the workpiece were obtained from DSP. they are better painted with any enamel or nitropaints, also in two or three layers. After finishing, you can begin to assemble the high chair.

 

Assembly

 

Equally important is the sequence of Assembly of prepared parts. First, are connected with hinges halves of both side walls of One of the raised sidewalls of the stacked loop down on a flat surface, it is both sides of the dock front and the rear. and the joints overlap and are attached with piano hinges. The same loops are attached at the edges of these panels for future connection to another sidewall, and the upper ends of the — loops, designed for one-half of the seat. It is now possible from one end of this “calculations” to attach the second side panel and fold panel. to be able to attach the other edge of the second sidewall.

 

It remains to attach the seat and laid on it gathered the support portion of the chair, to complete the Assembly.
