Description

Decomposable square container

Field of technology

The technical solution relates to a decomposable square container with a bottom, a lid and four side walls, which are mutually supported by each other by means of inwardly preventing stops, arranged in the corner area, and surrounded by bottom and lid projecting frames projecting against the side walls.

Prior art

In order to be able to pack the transported goods, for example machines or machine parts, preferably, expandable, square containers are used, which can be assembled without tools if possible. For this purpose, it is known (EP 1 818 269 A2, DE 7428549 U) to form the bottom of a container from a bottom plate with a circumferential, upwardly extended edge in the form of a frame which surrounds the side walls. Since the side walls in the corner areas are either cut to a miter or form a butt joint, the front surface of the next side wall extending beyond the side wall having a stop for the protruding side wall, the side walls in the corner area always abut each other, so that they cannot be of this mutual support are moved against the inside of the container. Due to the external encirclement of the side walls by the container bottom frame, the side walls are thus firmly held in position relative to each other, not only in the bottom area but also by a mirror-formed lid which surrounds the side walls on the outside by a corresponding frame projecting against the side walls. It is therefore only necessary to ensure that the bottom and the lid are not released from the side walls, which can be ensured in a simple manner, for example by means of clamping straps which surround the container.

In addition, the bottom and the lid can, on the basis of their mutually projecting frames, form a space-saving transport container for the side walls, which are arranged parallel to the bottom, respectively. between the bottom and the bottom-facing lid inside their frames. The disadvantage, however, is that additional means are needed to prevent the bottom and lid from moving relative to each other.

In order to be able to adapt the transport system to the various dimensions of the goods to be transported, in particular spare parts for motor vehicles, it is particularly known (DE 10 2007 032 336 A1) to provide a base pedestal with a bottom frame and plugs inserted in the corners of the bottom frame. of the modular system can be detachably connected to the side panels via corner connectors, so that various load carriers can be inserted into the established, square base base. The stackability of such base pedestals is achieved by means of upwardly projecting stop extensions arranged on the corner couplings, which engage in corresponding stop recesses on the underside in the corner region of the bottom frame of the base feet. However, transport systems of this type do not form a closed transport container, but have a frame-like base base, which is missing in the case of transport containers of the type mentioned at the outset.

The essence of the technical solution

The basis of the technical solution is therefore the task of creating a decomposable square container so that the decomposed container forms a sufficiently stable handling unit for transport, without compromising simple handling without tools during assembly or disassembly of the container.

Based on a decomposable, square container of the type mentioned in the introduction, the technical solution solves the stated task by connecting the arms of the bottom and lid frames to each other by means of drawer bearings for the ends of the arms forming the corner connectors and having the corner connectors on the facing sides of both frames in of the connected ends of the arms, on the one hand, a projecting stop and, on the other hand, a stop recess, the stop recesses of the corner connectors of one frame always lying against the stops of the corner connectors of the opposite frame.

The corner connectors between the arms of the bottom and lid frames first ensure a simple construction of the frame, because thanks to the given drawer bearings for the ends of the arms, the arms of the frame form a right angle with each other even without precise machining. In addition, the corner couplings offer an easy way to secure the bottom against the lid when these parts of the container are placed on top of each other in order to obtain a sufficiently stable handling.

- 1 CZ 30126 UI fastening unit for unfolded container. For this purpose, the corner couplings only have to have a protruding stop on one side in the region of the two interconnected arm ends on the opposite sides of the two frames and a stop recess on the other side, the stop recesses of the corner connectors of one frame lying against the corner connector stops by fitting the lid to the bottom, the protruding stops of the corner connectors of the lid frame engage in the stop recesses of the corner connectors of the bottom frame, and the stop recesses of the corner connectors of the lid frame receive the protruding stops of the bottom frame. The side walls inserted between the bottom and the lid are thus firmly held in a handling unit formed by means of a lid immediately mounted on the bottom.

If the corner connectors of both frames form on the side facing the bottom, resp. of the lid over the height of the frame, a projecting angle projecting for the bottom plate or the lid, so that the construction of the bottom or the lid can be the lid is further simplified because the position of the bottom plate or the lid against the frame is firmly anchored by means of the projecting contact angle. The drawer seats of the corner angles determine, on the basis of their wall thickness, that the bottom plate or the lids do not rest on the arms of the frame when the ends of the arms do not recede by the wall thickness of the drawer receptacles. This generally doesn't matter. However, in order to better fit the bottom plate and the lid on the corner connectors, it is recommended to provide the corner connectors between the arms of the contact angles with a bearing surface for the bottom plate or the lid. This abutment surface extending over the area of the inner corner provides, in particular, additional reinforcement of the corner connectors and thus of the frame.

Explanation of drawings

The drawing shows, by way of example, the subject of the technical solution. They show:

Fig. 1 a square container according to the technical solution with an open lid in a schematic drawing, Fig. 2 this container with a closed lid, Fig. 3 a corner connector for the arms of the bottom frame, resp. of the lid in the drawing and on a larger scale, and FIG. 4 is a section through an exploded container with a bottom-mounted lid in the area of the corner connector on a larger scale.

Examples of technical solution

The square container shown consists of a bottom 1, a lid 2 and mutually opposite side walls 3, 4. The bottom 1 and the lid 2 each have a frame 5, 6 projecting from the edge of the upwardly extending arms 7, 8 in a mirror-like arrangement against the side walls 3, 4. which are connected to each other by means of corner connectors 9. As can be seen in particular from FIG. 3, the corner connectors 9 in each case form two socket outlets 10 perpendicular to each other for the ends of the arms 7, 8 of frames 1 and 2. The arms 7 and 8 are glued together or firmly held by means of screwing by means of a first first angle by means of the corner connectors 9.

From the bottom, resp. lids, the walls forming the outer corner of the corner connectors 9 are extended over the height of the frame into the abutment angle 11 for the bottom plate 12, 13, respectively. of the lid, which is thus held positioned precisely inside the abutment angle 11 and must therefore be connected in a corresponding manner only to the corner connectors 9. The corner angles 9 form a bearing surface 14 for the bottom plate and the lid, which extends over the inner corner of the corner connectors. 9 and ensures good support of the bottom plate 12, 13 and the lid on the corner connectors 9.

On the side opposite the bottom plate 12, 13 and the lid, respectively, the corner connectors 9 have a stop 15 projecting on one side and a stop recess 16 on the other hand in the region of the drawer seats 10 for the ends of the arms 7, 8. The arrangement is arranged such that stop recesses 16 of the corner connectors 9 of one frame 5, resp. 6 lies against the projecting stops 15 of the corner connectors 9, always of the opposite frame 6, resp. 5. Thus, if the lid 2 is fitted directly to the bottom 1, as can be seen from FIG. 4, mutual interlocking between the corner connectors 9 of the two frames 5, 6 is provided by form-fitting means by means of interlocking stops 15 lying one on top of the other. corner connectors 9, thus preventing displacement between the bottom 1 and the lid 2.

To assemble the container, the side walls 3, 4 are fitted into the frame 5 of the bottom 1. The side walls 3 overlap from the side walls 4 from the front side, as can be seen from FIG. 1. The side walls 4 always form a stop 17. on which the adjoining side wall 3 rests, so that, on the basis of this mutual support, the side walls 3, 4 cannot be moved against the inside of the container. After fitting the lid 2, the assembly of the container is completed. To secure the lid 2, the container is surrounded by clamping straps 18, as indicated in Fig. 2. These clamping straps 18 can be guided through the through-slots 19 in the bottom plate 12, 13 and the lid to secure them in position.

The container is unfolded in the reverse order by first removing the lid 2 before the side walls 3, 4 are released from the frame 5 of the bottom 1 and placed on the bottom 1 inside its frame 5. Then the lid 2 can be fitted on the bottom 1 according to FIG. 4 in order to obtain a stable handling unit for the unfolded container.

Industrial applicability

The container according to the technical solution can be used for the transport of goods, for example machines or machine parts.
