The invention relates to a container according to the generic term of the main claim&igr; in particular a collapsible container*

Until now*, demountable suitcases or briefcases consisted of so many individual parts that their production could not be cheap. Apart from the high production costs, assembling the many parts was difficult and time-consuming.

The invention is therefore based on the object of developing a collapsible container while avoiding the disadvantages described above.

This object is achieved in a generic container according to the preamble of the main claim by its characterizing features. The invention also has the advantage that the collapsible container consists of relatively few parts and is easy to assemble and disassemble.

Details and advantages emerge from the following description of the invention, which is explained in more detail with reference to the accompanying drawings. In this drawing:

Figure 3 shows an opened, all-purpose container according to the invention in perspective view*

From Figure 1 it can be seen that the present structure has 3 side pieces 1, corner pieces 2 and end pieces 4. Although only one of the mentioned parts is shown in Figure 1, it is self-evident that due to the symmetry, more than one part of each section exists.

The main parts are flat and rectangular in plan view and are provided with a projection 31 on each of their four edges for engagement with an end or side piece, as will be explained in more detail later.

Figure 2 shows that the upper and lower side pieces 11 and 12 and the lower end pieces 42 are essentially the same. Even though the upper end pieces 41 are not shown in Figure 2, they are essentially the same as the upper side piece 11, but they are shorter. The cross sections through the upper end piece 41 and the upper side piece 11 are identical.

The basic structure of the upper side pieces 11 and the upper end pieces 41 (see Figure 3) is described below. The upper pieces 11 and 41 have very thin walls which partially enclose a cavity 17, with a groove 16A and a projection 111 which also enclose the cavity 17. The two walls are curved so that the two ends of the walls are substantially at right angles to each other.

* An upper partition wall 15A forms two walls and at the same time forms the inner surface 16 in the area of the upper end of two walls. In addition, the upper partition wall 15A gives the upper soap bar II a high degree of shape and structural stability without being at the expense of the weight of the upper side piece 11.
The lower end of the upper side piece 11 is provided with a projection 111 of the ZV?61 turn

It should be noted that the lateral ends of all side and end pieces are open so that they can accommodate the ' ' projections 28 of the corner pieces 22.

The lower side pieces 12 are essentially mirror images of the upper side pieces 11, but the lower side pieces 12 are provided with a groove 18 on the upper end into which the projection 111 of the upper side piece 11 engages. Like the upper side pieces 11, the lower side pieces 12 also have a partition 15C which forms a groove 16B, but the partition 15C and the groove 16B are arranged at the lower end of the lower side pieces instead of at the upper end. Hinges 4 are required between one of the lower /- \ side pieces 12 and one of the upper side pieces 11.

The lower corner pieces 22 are explained in more detail below (Figure 2). The lower corner pieces 22 basically serve as connecting pieces to hold the lower corner pieces 42 and the lower side pieces 12 together. Like the lower side pieces 12, the lower corner pieces 22 each have a groove 221 to accommodate the projection 211 (with the same cross-sectional area as the projection 111 on the upper

Side piece ll) of the corresponding corner piece 2l on* The lower corner pieces 22 also have a projection 28 at the respective lateral end, which is firmly fitted into the hollows 17 of the lower string or end pieces 12 { and 42 and so the lower half of the

The screw holes 14 of the end and side pieces correspond to the screw holes 281 in the projections so that all the parts can be secured to one another with screws after assembly (not shown).

As Figure 3 shows, the upper corner pieces 21

\ provided with projections that fit into the cavities 17

the upper side and end pieces 11 and 41 are fitted* The main difference between the upper part of the inventive container and the lower part lies in the projections (111, 411 and 211 respectively) which all upper pieces 11 and 41 and all upper corner pieces 21 have at their lower ends, which fit into the corresponding grooves 18, 421 and 221 respectively. The groove 18 is formed by a further partition wall 15B, so that the lower pieces each have two partition walls 15C and 15B.

Claims (1)

Claim for protection marked by two main parts (3) which are flat and rectangular in plan view and each of which is provided with a first projection (31) on all four edges; by four upper pieces which have two upper side pieces (11) and two upper end pieces (41), the upper pieces (11 and 41) being made of two thin walls with an intermediate wall (15A) at the upper end and with a groove (16A) which is formed at the upper end of each upper part (11 and 14) for receiving a projection (31) of the main parts (2) and with a second projection (111) r · ■ ■■■ ■ · · · r« at a lower end of the upper parts (11 and 41); by four lower pieces having two lower side pieces (12) and two lower end pieces (42), the lower pieces (12 and 42) having two thin walls with a central intermediate wall (15B) at the upper
ends and a lower intermediate wall (15C) at the lower ends and provided with a groove (16B) for receiving the projection (31) of the main parts (3) at the lower end, each of the lower pieces (12 and 42) also having a groove (18 or 42.i) for receiving a projection (111 or 411); and W by eight corner pieces comprising four upper corner pieces (21) and four lower corner pieces (22) forming substantially a right angle between their ends and with two projections (28), one at each end of the corner pieces (22) for respectively engaging the cavities (17) on one of the side or end pieces.
