Plug-in part

The innovation concerns a corner part for a connecting device for a detachable connection between two walls of a collapsible container, of which at least a first is provided on its outside with plug-in sockets and the second, adjacent one on its outside with plug-in parts for insertion into the plug-in sockets and for bending a protruding section thereof over the upper edge of the plug-in sockets away from the first wall for firmly connecting the walls.

The definition of "walls" also includes the lid and the bottom of a container.

Such plug-in parts are already known, for example from DE-PS 21 02 003, but these cannot be brought into their connection state as reliably as would be desirable using simple means. When bending the tongue-like plug-in part section to create the connection, a lack of precision or haste can easily lead to a bending line that runs diagonally with respect to the upper edge of the plug-in socket. It is easy to see that the respective walls of the container thus formed are not connected to one another completely rigidly, which means that the container loses stability.

*: The innovation is based on the task of creating a plug-in part for

e to create a connecting device of the above-mentioned type,

\ which can be achieved with very little effort and very simple means and no

■' special accuracy the hands of a container to a precisely

■k defined way and allows the combined

f\ Container a grosca stability through rigid

jji binding of its walls.

This task is solved by the features contained in the characterizing part of claim ■ 1.

Thanks to the innovative solution, the individual plug-in part

in a precisely defined manner in a bending area over the upper edge of the respective socket, and

.: this even if the plug-in sections are % forces do not act in the desired bending area. The % stiffness range thus enables with very little effort the The respective plug-in part must always be bent so that a rigid

t connection of the two container walls.

; In a preferred embodiment, the plug-in part according to the innovation has a hole in the section to be bent designed to receive a tool part, whereby a screwdriver or a similar simple tool can be used for correct

: Bending the plug-in section can be used. This eliminates the need to lug hammers and similar tools around.

An innovative plug-in part 1 made of metal has fastening means 2 in the form of sharp, bendable tips 3 which can be driven into a container wall. The plug-in part 1 consists of a single piece of metal and the fastening means 2 are obtained by punching. Fig. 3 shows how the corner part is fastened to the edge of a container wall. The plug-in part 1 has a tongue-like section 4 which projects above the container edge. This section has two impressions 5 which run essentially parallel to one another. These impressions form grooves 6 on the side shown in Fig. 1 and ridges 7 on the side shown in Fig . 2 on the protruding plug-in section 4. The impressions 5 represent stiffeners so that it is very difficult to bend the cut in this area of the plug-in section 4. The connecting line of the end points 8 of these impressions 5 remote from the front edge of the section to be bent defines a bending line of the plug-in part. When the plug-in part 1 is fully inserted into a plug-in socket 9 (Fig. 4), this bending line runs close to the upper edge 10 of the plug-in socket, so that the bending always takes place directly on the edge.

The section 4 of the plug-in part to be bent has a hole 11 designed to receive a tool part. The hole 11 is located on a center line of the section to be bent, which runs essentially perpendicular to the bending line, in the

· I

Area between the elongated stiffening impressions 5. The container 12 is preferably provided with a tool 13 for insertion into the hole 11.

The connection of two walls is realized as follows: the one wall 15, which has sockets 9, is placed on the other wall 14 in such a way that the sections 4 of the plug-in parts 1 are pushed through the sockets 9. Then one end of the tool 13 is pushed through the hole 11 from the comb side and then it is swung in the direction away from the first wall 15 (clockwise in Fig. 4). Thanks to the indentations 5, the section 4 will be folded along the bending line defined by its end points 8 and the upper edge 10 of the plug-in part 9 - even if the forces applied by the tool 13 were to run obliquely to this line. The stiffening indentations prevent the plug-in part from bending in their area. This means that a very precisely defined bending line is achieved, even if the forces applied to section 4 are not in the most favorable way. The rigid connection shown in Fig. 5 is therefore always achieved.

It would be possible to replace the indentations 5 with other types of stiffeners. The number of stiffeners could be any, for example 1 or 3, whereby in the case of a single stiffener it might be useful if it had a large cross-section to prevent undesirable bending lines.

Of course, the connection could also be made by bending section 4 in the opposite direction (anticlockwise in Fig. 4).
