Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foldable structure that transforms into a rigid structure when unfolded.

Rigid structures are needed for many purposes, such as tables, beds, beams, posts, ladders, profiles, wire, stretchers, scaffolding, stages, piers, ramps, etc. These rigid structures are manufactured in factories and transported to locations where they are used. Alternatively, they are assembled at such locations from various pre-assembled parts. Both methods are undesirable and somewhat complicated. They require large storage spaces, many means of transportation and/or large amounts of manpower.

Therefore, it can be opened easily and quickly,
It is desirable to construct rigid structures such as any of the above, as well as bendable structures that can be transformed into any other suitable structure, such structures being easily manufactured. It should not be very expensive, require relatively little storage and transportation space and means, and should not be very expensive.

The invention therefore provides a foldable structure consisting of at least one row of plates and a row of side flaps on at least one side of the row of plates; ) where there is only one row of plates and one row of flaps, the various plates, the various flaps, and the plates and corresponding flaps between them are respectively hinged to each other; and .

(b) where there is more than one row of plates and/or flaps and at least two sets of hinges, in both the plate row and/or flap row;
arranged in such a way that alternating plates and/or flaps may be missing, provided that both adjacent plates and/or flaps are not missing; said flaps are folded in the direction of said plates; possible; the plate and the folded flap are pivotable about an axis; and the fastening and fixing means ensure the rigidity and/or position of the final structure.

The plates and/or flaps may have any suitable geometric shape (e.g. square, rectangular, trapezoidal, etc.); several consecutive plates may be made of cloth,
It may be constructed of a strong and flexible material, such as a suitable plastic material, such as canvas, waterproof canvas, etc., such material being bendable and extending at right angles to the direction of rotation. It can be rotated freely around a virtual axis. The plate and/or flap may be a finished product or, as the case may be, one or two
It may also be designed as a structural element that opens on two sides.

The dimensions and thickness of the plates and/or flaps are not critical features of the construction according to the invention; they are selected depending on the requirements and dimensions in the final construction. The successive plates and/or flaps may not be of comparable size and/or geometry.

The structure according to the invention generally consists of more than one row of plates and/or flaps. The number of said plates and/or flaps extending parallel to each other and adjacent to each other is also selected according to the requirements of the final structure. A row of flaps may be present on one or more sides of the row of plates.

The fixing means may be any suitable hinges, rods, pins, etc. suitably arranged. They may also be constituted by teeth and corresponding recesses in the adjacent plates and/or flaps.

The fastening means may in some cases be similar to the fixing means, however they are usually locks, cables, lobes, cords, springs, etc. Said additional means may also be present in addition to other fastening means.

The axes may be structural, for example part of the fixing and/or connecting means, about which the plates and/or flaps can rotate; however, they may be virtual axes indicating the axis of rotation. You can.

The structure according to the invention must be opened entirely in the same direction and must not be fastened. Thus, for example, one row of flaps can be folded in one direction and a second in the opposite direction. In some cases,
It is advantageous to assemble the structure in a flat state, ie without folding the flaps inwardly or outwardly.

All structures can be folded in any desired manner.

The structure according to the invention can be made of any suitable material, such as steel, aluminum, etc., provided that the structure made of that material is bendable and the structure in the final open state is rigid. It can also be manufactured from metals such as, some plastic materials, etc.

It is easy to see that the structure according to the invention substantially overcomes the aforementioned drawbacks. In the folded state, it requires relatively little storage and/or transportation means; it can be easily assembled, ie opened and changed into a rigid state, whenever necessary.

It is also readily understood that the scope of application of the structure of the present invention is very large. The possible variations depend on many factors, such as the number of plate and/or flap rows present, their shape and dimensions, their different arrangement, the type of fixing and/or fastening means, etc.

The invention will now be described with reference to the accompanying drawings. Similar parts are designated by the same reference numerals. When there are many similar parts in the same drawing, only one part is numbered.

It is folded outward as shown in Figure 2b. Some of the plates 10 are missing, forming doors or windows.

The staircase shown in FIGS. 3a and 3b consists of a plate 15 and a flap 16. The plate 15 and the flap 16 are
They are hinged to each other at position 17. The plates 15 are connected by a cord 19 and a pin 20 passing through a hole 21 with various steps connected to each other by another hinge L8, which also constitutes an axis of rotation.

The wire shown in FIGS. 4a and 4b consists of a plate 25 and a flap 26. The plate 25 and flap 26 are
The plate 25 and the flap 26 each have two
0 connected by hinges in position 7
As is clear from Figure 4b, some of the flaps 26 are connected by cables 28 between them, although the hinge is not necessary in all positions.

The shelf shown in FIGS. 5a and 5b consists of a plate 30 and a flap 31. The plates 30 are hinged therebetween by a hinge 32 which also constitutes an axis of rotation. The flap 31 is hinged to the adjacent plate 30 by a hinge 33 and connected therebetween by a cable 34.

The table shown in FIG. 6 includes a plate 35 and a flap 36.
Consisting of The outer flap 36 extends as a leg 36'. The plate 35 and the flap 36 are hinged to each other in a manner similar to that shown in FIGS. 1a and 1b as well as between the flaps 36. The table is bonding material 3
7 and a spring 38.

The table shown in FIG. 7 is designed similarly to that shown in FIG. However, many of the flaps 36 include legs 36'. Some of the legs 36' are connected by cords 39 passing through holes 39'.

The ladder shown in FIG.
1a and 1b, as well as between the flaps 42.
are hinged to each other in a manner similar to that shown. The fastening means are similar to those shown in FIGS. 6 and 7.

The stretcher shown in FIGS. 9a-9d consists of flaps 50 hinged together by hinges 51. The stretcher shown in FIGS. Some of the pairs of opposing flaps have bonding material 52 (
The bonding material 52 and the plate 56 are connected to each other by means of fastening means (also configured with fastening means). The flap 50 at the end is provided with a handle 55 to allow the stretcher to be carried. The plate is constituted by a canvas 53 provided outside a hole 54 through which the flap 50 passes. The axis of rotation when folding the flap 50 inward is the connection point of the canvas 53 to the flap 50. The second axis of rotation is the line along which the hinges 51 connect to each other.
