Description

The invention relates to a container,

Container

crate and the like comprising a bottom panel and a plurality of side panels which can be engaged and engaged with the bottom panel, a connecting fitting between the side panels and the side panels and the bottom panel, the connecting fittings comprising at least partially profile elements in U-shaped with which the coupling elements provided with a free locking arm can be engaged.

BACKGROUND OF THE INVENTION

For many purposes of packaging, in particular for the distribution of machine parts and apparatus, container formwork, i.e. containers consisting of interconnected packing elements, or containers such as boxes with side walls, possibly reinforced with internal struts, usually of wood, are usual, the assembly of such containers is accomplished by means of nails or screws, and removal of the packaged goods at the point of delivery is often associated with the destruction of the container. In a conventional crate for the packing of reinforced multi-layer wood or wood waste panels, the individual crate panels are connected to each other by metal clamps, while there is still the risk of losing metal clamps during transport or after dismantling, and relatively complicated, not very safe assembly.

Prior containers, which are considered within the scope of this application both container formwork consisting of individual interconnected elements and closed containers, such as boxes with closed side walls, for example for dispatching machines or machine parts, are therefore at the point of dispatch, and at the point of opening at the point of reception, to the extent that it is inconvenient to assemble and disassemble them, considerable effort is required to deploy the corresponding tools. During assembly, there is also the problem that, often after complete assembly of the box body, sufficient inherent stability is achieved, whereas during the assembly itself, manual fixation of the individual parts is necessary before they are fixed together, possibly with the participation of several persons. In addition, in the case of crates, the packaged articles can often be inserted into the containers only from the top, since there is no lateral access to the interior of the container or the box.

The removal of the fasteners when opening the container or the container or the container form often results in irreparable damage as a result of the use of the tools, so that it is often not intended to reuse the container or it does not make sense to return the container to its starting point.

DE-C-353 914 discloses a collapsible container of the above type with interlocking fittings. However, many different types of fittings are used here. In addition, the assembly and disassembly of the container is not simple enough.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve a container of the above type so that, even when the container is highly stable, even in a partially assembled or disassembled state, a quick and simple, cost-effective assembly or disassembly is possible.

SUMMARY OF THE INVENTION

According to the invention, this object is achieved by a container of the type mentioned above, which is characterized in that the U-shaped profile elements are provided at least partially with a profile body along the inner side surfaces to form an angular shaped interior space.

According to the solution according to the invention, the respective engagement elements can be brought into the ridge engagement, for example engagement angles and U-shaped profile elements of adjacent right-angled side walls or U-shaped profile elements of opposite side parts cooperating with the engagement angles of the bottom part. After assembly, the element forms, with the preceding element, a separate, positionally stable unit and allows for a very simple assembly of the packaging body, which is also highly stable.

In this connection, the connecting elements can be formed by fittings, the engagement angles, in particular the metal angles, are provided with free locking arms, the engagement angles extending into the U-shaped profile elements having a counter-shape to the engagement angle, such fittings allowing rotational engagement of the engagement angle. but also a ridge lock by a linear relative movement.

Thus, the connecting fittings may on the one hand be formed by the same engagement angles, for example sheet metal angles, and on the other hand may be formed by profile rails or U-shaped parts which are provided along at least partially a profile body along the inner side surfaces of the profile. a negative shape to the angle in the profile bar or U-shaped section, so that, as profile bars or U-shaped sections embedded in the bottom plate, they form a counterpart along the two opposite edges of the bottom plate for the free locking arms of the respective angles or sheet metal angles into which they are established by transverse or rotary movement, so that it is not absolutely necessary for the locking engagement to take place a relative transverse movement between, for example, the side panels and the bottom panel, and for example the side panel may be It is moved from a horizontal position to a vertical position by a rotary movement and then, when the free locking arm engages in a U-profile with a profiled angle, it is self-bonded to the bottom plate.

In order to form an anti-engagement angle by means of such a profile bar or a U-shaped section, the profile bodies embedded in the U-shaped elements are preferably formed by profile bars, especially triangular, rectangular or semicircular cross sections or half polygonal cross sections that are welded. with U-shaped side wall.

Optionally, a U-profile can also be used, one profile arm of which is designed to protrude inwardly, wherein the shaped counterpart or its interior space is formed integrally by extrusion.

Advantageously, the U-shaped profile element is provided on one profile arm with a system of spaced apart inwards U-shaped projections, which form an internal space partially in the form of an angle for engaging the free locking angle of the engagement angle.

The assembly of the individual components, i.e. of the individual shuttering elements and of the closed plates, provided with reinforcing rungs, for example, on their inner side, means that the free locking arms of the engagement angles for the ridge engagement are engaged and locked either relative relative to each other the internal space of the U-shaped profile element formed into a negative mold by a rotation of 90 ° and / or a linear relative movement.

Preferably, the U-shaped profile rails or parts which are ready for engagement of the free locking arms of the engagement angles are simultaneously made so that engagement with the lateral displacement of the free locking arm is also possible so that the U-shaped profile rails or parts are from one inner side wall tapered, they can be used both as part of the swivel fitting and as a sliding fitting, with a free blocking arm of the engagement angle engaging in a blocking manner from the front.

In many cases, especially in the case of a container-like construction, it is desirable to close the container with a lid part.

By means of the connecting fittings according to the invention, in addition to the connection by turning the locking arm into the angular interior of the U-shaped profile element, it is also possible to engage transversely between the free locking arm and the inner profile of this unilaterally tapered U-shaped profile element. The sliding engagement from the front side into the angular interior of the U-shaped profile element, at the same time forming a ridge engagement.

Further advantageous embodiments of the invention are set forth in the remaining dependent claims.

Exemplary embodiments of the invention

In the following exemplary embodiments, the container is illustrated as a cuboid container 100 that can be assembled and disassembled virtually without the use of assembly tools, yet can be stably and safely transported without additional fasteners, and can be unfolded without damage while returning of the individual elements of the container 100 after they have been disassembled at the packaging site.

The invention will now be described by way of example with reference to FIGS. 1 to 17.

The base member of the container 100 is a bottom member 102 that determines the base mass of the container 100 and, in the present exemplary embodiments, has a rectangular shape with side and front sides.

In the present exemplary embodiment of Figures 1 and 2, the bottom panel 102 is rigidly connected to the pallet 103, but this is not absolutely necessary. However, this provides a very stable transport unit for transportation by a forklift, and increases the overall stability of the assembled container 100. The pallet 103 may be a Europallet or may be replaced, for example, by skis that are integrally formed with the bottom 102. trouble-free transport using a forklift. In this exemplary embodiment, the bottom panel 102 consists of a plurality of bonding board layers of glued plywood layers of about 20 mm thickness.

For clarity, reference will be made to Figs. 3 to 15, while an illustration of this exemplary embodiment is shown in Fig. 1, with an elevation of the bottom panel of this exemplary embodiment in Fig. 2.

In this case, to form the swivel / slide fitting, on the one hand, the sheet metal angles like the engagement angles 104 are connected (screwed) directly to the side panels 105 (wall plate 106) along their lower side and along the vertical sides so that there is a relatively short, free locking arm 104b is spaced from the underside of the wall plate 106, this spacing being given by the profile width of the U-shaped profile rail or profile member 120 that forms an anti-engagement angle. The profile rail or U-shaped section 120 forms an anti-engagement angle with its angular profile interior 104 which is negative to the locking ridge engagement with the free locking arm 104b of the sheet metal angle 104 so that along one inner surface of the profile rail or profile-shaped section The profile bar 121 is fixed at least partially, in particular it is welded to the profile bar arm 120, the profile bar 121 having a shape that allows the bent region of the sheet metal bracket 104 to latch with the free locking arm 104b when straightened from the horizontal position shown. 3 to the vertical locking position shown in FIG. 4. In FIGS. 3 and 4, the profile bar 121 has a triangular cross-section. This allows the angle bracket 104 with the anti-engagement bracket formed by the profile bar or the profile member 120 of the angular-shaped interior 104 not only to be locked, but not only by the swinging movement shown, but the free locking arm 104b of the sheet metal bracket 104 The feed fitting, which can also be used as a swivel fitting, is retained in the longitudinal direction in the profile bar or the U-shaped section 120 so that the sliding engagement between the free locking arm 104b of the engagement angle 104 and the engagement angle formed a specially profiled angle bar or a specially internally shaped U-shaped profile section 120 (as a sliding fitting).

FIG. 3 is a partial cross-sectional view of a structure in which a plurality of U-shaped profile members 120 are attached to the bottom panel 102 in longitudinal direction along the side of the bottom panel 102, which are connected to a pallet 103. a support along the inside of the U-shaped section 120 but is not absolutely necessary.

Although not shown here, in such a case, the distances between adjacent U-shaped profile members 120 along the side of the bottom member 102 are filled with profile bars of corresponding height, otherwise the flat support of the wall plate 106 arranged in the mounting position vertically would not be given (see FIG. 4). Fig. 4 shows an alternative embodiment which removes this condition by having the U-shaped sectional part, as also shown in Figs. 1 and 2, each embedded in the bottom section 102 with its edges and being embedded in its bottom surface. 4, the wall plate 106 is supported on the upper side of the bottom panel 102. In FIG. 4, the pallet is indicated by 103.

Alternatively, with respect to the assembly of FIG. 3, a continuous U-shaped profile rail 120 could of course also be selected.

Referring now to Figures 5 to 9, various embodiments of U-shaped profile rails 120 with angular shaped internal space are shown, wherein the welded profile bars 121 in these figures have a different shape, with a triangular, semicircular or rectangular cross-section. Alternatively, it is of course also possible to produce the profile bar or the U-shaped section 120 by extrusion itself with the corresponding one-sided profiled arm as an integral profile which allows not only a sliding engagement of the free locking arm 104b in the longitudinal direction but also a rotating engagement of such locking arm 104b. without having to use separate profiled bars 121 (see FIG. 8).

Instead of the overall profiling of the unilaterally profiled arm of the U-shaped profile rail 120, it is of course also possible to provide the U-shaped profile rail 120 on one side with a system of spaced apart inwardly extending notches 12a to create an angular interior space with which the free locking arm 104b of the respective engagement bracket 104 (see FIG. 14) may be both slidable and rotatable. Giant. 13 shows a cross-section of an area of such an angular 121a inner space 104 in the U-shaped profile rail 120.

In Figures 10 to 13, the cross-sectional shapes of the profile rails and / or the U-shaped sections 120 are provided with profile bars 121 to form an angular profile of the interior space, the angular profile of the interior spaces being designated 104, respectively, the angles 104 with their free locking arms 104b each time a ridge engagement is made between the two angles 104.

In FIG. 14, the metal bracket 104 is shown as an engagement bracket, as always mounted without additional reinforcing elements or rungs on the side panels 105, as shown in the exemplary embodiment of FIG. 1, which shows a container without a lid.

Due to the usability of the U-shaped engagement arms 120 as both swivel and sliding fittings, such U-shaped rails or panels 120 can also be used in the wall plates 106 so that, as shown in FIG. 15 by means of a cut-out, for example the side wall 106 can be rotatably engaged with the engagement angle 104 about a vertical perpendicular axis (when the end wall 113 is already available) or, after corresponding mounting of the wall plate 106, the end wall 113 can be slid from above (see FIG. 15, the front wall with the U-shaped profile strips 120 vertically along the side edges with the profiled bars 121), in which case the specially internally profiled engagement angle formed by the U-shaped profile rail 120 engages the free engagement angle locking arm 104b. 104 side walls 106.

In addition, in Fig. 15, a different shape of the profiled bar (rectangular shape) is indicated by broken lines, while generally a triangular profile represented by solid lines is preferred.

By means of the above-mentioned embodiment, it is also possible to fold or tilt the side walls on the box and rotate them without the need for a linear relative movement of the interlocked parts, in particular the side walls 106 and the bottom part 102.

FIG. 2 is a front elevational view of a bottom panel 102 with rotatable fitting in the form of internally profiled profile members 120, which is embedded therein, in which case the side walls 108 are pivoted from horizontal to vertical as shown in FIG. 3 and 4. When installing the U-shaped profile rails 120, which would also allow lateral sliding of the free locking arms 104b of the respective engagement angles 104, stops may be provided in the U-shaped profile rails 120 which may also prevent relative relative movement the locking arm 104b and the U-shaped profile member 120 in the direction of its longitudinal axis.

It is also pointed out that, without being shown separately here, an additional interlocking device (pendulum plate) which engages within the assembled container can be rotatably movable either on the side wall 106 or on the end wall 113 near the corners. into the groove of the cooperating fitting parts (engagement angle 104, profile rails 120), so that after the end walls 113 have been assembled and the locking plate has been rotated, the end walls 113 can no longer be pulled out, but the front walls 113 can only be removed. The container 100 in the embodiments described above is referred to as the mc box.

As mentioned above, lid closing 114 is preferred in many containers. To lock the position of lid 114 when container 100 is closed, a locking device 30 is provided on the lid 114 without loss, shown schematically in Figure 16 in side view. 17 is a cross-sectional side elevational view of FIG. Thus, a hollow profile member 31 having a protruding inner stop 32 at its inner end is screwed to the end plate 15 at the end ends. Otherwise, in this exemplary embodiment, the hollow profile member 31 is rotatably supported by a pin 33 at the end end of the hollow profile member 31. a clip 34, which, after the lid 114 has been inserted into its final closing position of the container 100, can be transferred from the pre-position shown in FIG. 17 to the final, lowered full line position with the closing clip 34 abutting the outside This is to ensure that the lid 114 can be locked without loss and can also be easily opened by tilting the locking clip 35. The end wall 113 is in the region of the hollow profile section. 31 fitted with recess, as it stmp See Figure 17.

The container according to the invention is not limited to the exemplary embodiments mentioned, for example it is also possible to provide a formwork in this way, wherein the engagement angle 104 and the U-shaped profile elements 120 are each arranged at the ends of the plug elements which are in ridge engagement with each other and through reinforcing transverse and longitudinal cross members.

An exemplary embodiment has been described on a container 100 which consists essentially of wooden parts with metal engagement angles for locking.

Alternatively, it is of course also possible to use completely different materials for the container, for example metal, especially aluminum, or a combination of wooden parts provided with metal fittings. It is also possible to produce engagement angles in one piece with the outer plate parts. The free locking angles 104b of the engagement angles can also be made as integral protrusions of metal profiles, or, for example, in a plastic design as an integral profile formed by extrusion. The ridge-shaped engagement of the free locking arms with U-shaped profile elements is essential, resulting in a completely stable shape of the packaging body.
