Utility Model Implementation

A utility model relates to a piece of furniture assembled from a single piece of sheet material cut along a special contour and having pre-drawn fold lines along which the material can be bent, forming a piece of furniture ready for use - a chair, and at the same time it can be laid out in source flat sheet.

The figure 1 presents a General view of a collapsible chair (1) in the unfolded state in the form of a flat sheet with its corresponding parts and areas. Regions (6) and (7) are located on opposite sides of the first region (4), which form the lower sides of the ready-to-use chair, which are attached by hook to the lower rear parts (8, 9), which are inserted one into the other after how areas (4, 5, 6, 7, 10) will be folded to form a ready-to-use chair.

A flat piece of a single material also has pre-applied lines of the first and second fold. The lines of the first fold consist of four curved lines (2), the ends of which converge in pairs with each other, forming in the space between these four lines the first region (4), while each of these previously drawn lines of the first fold (2) borders and separates from the first area (4) one of several additional areas (5, 6, 7, 10).

The lines of the second fold (3) are straight and when folded along which the material is folded, turning into an envelope convenient for carrying.

Parts of the additional area (10) that adjoin each other in a state when the areas are folded into the finished chair are equipped with connecting devices (11, 12), which can include, among other things, Velcro Velcro, bolt and nut, lock -latch.

In addition, on a number of parts of the collapsible chair, parts of the fixing element are provided (see, Fig. 3, item 13), which, if the chair is put into an inoperative state, can be interconnected so as to ensure mutual tight fixation and pressing all parts of the chair relative to each other. This fixing element, formed by parts (13), is a Velcro Velcro, a bolt and nut, a snap-lock or button and its mating part. The main important point is the possibility of tightly pressing all parts of the chair to each other to eliminate the occurrence of tensile forces during transportation of the chair inoperative.

As a result of the test tests, it was recorded that with the introduction of a fixing unit that provides tight fixation of its parts when folded, the service life of the bend points and, accordingly, the chair as a whole is extended.
