Description

The present invention relates to a carrier for storing and transporting empty or loaded containers, especially in automatic warehouses, with a bottom forming a rectangular top surface and a floor revolving around the bottom, the support surface upstanding edge, wherein at the bottom of a securing device is arranged with at least one resilient stop member having an upper element part which projects in an unloaded state on the support surface and secures container on the support against lateral slippage and in a loaded by an attached container state in a flush with the support position is depressible.

The stop elements make it possible for such carriers to be used for receiving both individual and multiple containers of different sized base area, wherein the / the container is prevented by the stop elements on an undesirable, easily leading to damage slipping / are.

A carrier of the type mentioned is out DE 298 14 925 U1 known. In this carrier, at least one resiliently mounted, passing through the ground and provided with a over the support projecting head provided stop element. For resilient mounting of the stop element, a leaf spring element is disclosed in this document, is attached to the approximately in the longitudinal center of the head of the stop element. The two ends of the leaf spring element are each fixed in a rib of the rib-reinforced bottom.

A disadvantage is considered in this known prior art that the production of the stop element is relatively expensive, because it has a leaf spring element and an attached thereto or molded head.

For the present invention, therefore, the task is to provide a support of the type mentioned, which can be made easier without affecting its function.

The object can be achieved according to the invention with a carrier of the type mentioned, which is characterized in that the / each stop element is formed in the form of a leaf spring forming the upper element part.

With the invention is advantageously achieved that the / each stop member no longer has a special head, but only consists of the leaf spring itself, since the leaf spring also forms the upper element part of the stop element. The leaf spring can be easily formed with respect to the required shape and applied by her spring force. As a result, the stop element is structurally simple, which enables production with reduced effort and at a lower cost.

Furthermore, it is advantageously provided that the / each leaf spring has an arcuate course, wherein a bow apex region forms the upper element part of the stop element, which projects in the unloaded state on the support surface upwards. In this way, a good and protected leadership of the leaf spring in the soil is achieved because the / each leaf spring is in two spaced, lying on either side of the arc apex areas always within the soil. Only the arc peak area of the leaf spring protrudes in the unloaded state on the wing. In the loaded condition, the bow vertex area is also in the ground.

In a preferred embodiment of the carrier according to the invention it is provided that the / each leaf spring is designed as a clamped at its one end and at its other end free tongue leaf spring. As a result, only a single attachment point between the / each stop element and the bottom of the carrier is required, which leads to a further simplification of the production of the carrier.

The connection of the / each stop element with the rest of the carrier can be done in different ways. Preferably, the / each leaf spring is latched or clamped or welded or glued at an area remote from its free end with the ground.

An alternative embodiment of the carrier suggests that the / each leaf spring is clamped and / or supported at its two ends. The bending loads of the leaf spring are distributed here on two different areas of the leaf spring, which can be particularly favorable for mechanically highly loaded leaf springs and / or with which greater spring forces of the leaf spring can be easily realized.

It is expedient the / each leaf spring latched at its two ends to the ground or jammed or welded or glued. In a latching a leaf spring end or both leaf spring ends may be connected in its longitudinal direction relative to the ground limited movable with the latter.

For the purpose of space-saving accommodation and to protect against damage caused by external forces, it is proposed that the / each leaf spring is arranged in a recess of the floor and that the / each leaf spring is guided and supported at its lateral edges by the recess laterally bounding surface areas of the soil , In particular, the leaf springs are so effectively secured against twisting or bending, so that they safely retain their desired function, even if relatively heavy containers are loaded onto the carrier.

In order to provide the wearer with the lowest possible dead weight, a high load capacity, it is further provided that the bottom is carried out on the upper side or underside or top and bottom ribbed.

For cost-effective mass production of the carrier, the invention proposes that the carrier per se, i. without stop elements, an injection molded part made of plastic and that the / each stop element is also an injection molded part made of plastic or a metal part or a plastic-metal composite part. It is essential that the stop element has resilient properties. In this case, the stop element when executed as a composite part, e.g. be a plastic-coated metal spring. The metal is suitably spring steel or spring bronze.

The carrier can be used anywhere where containers with or without Gutstücke or unpackaged Gutstücke, which does not always fill the carrier's surface completely, must be transported and stored, in which case, in particular, to automatic goods or parts storage is to be considered. According to the invention, it is preferably provided for this that the carrier is a tray or tray or tray or a small pallet or even a container.

Followings embodiments of the invention will be explained with reference to a drawing. The figures of the drawing show:

1 a carrier in a first embodiment, in a partial view obliquely from above,

In the following description of the figures, the same parts in the various drawing figures are always provided with the same reference numerals, so that not all drawings have to be explained again.

1 shows a carrier 1 in a first embodiment, in a partial view obliquely from above. The carrier 1 has a rectangular outline and consists of a floor 2 as well as a surrounding, raised edge 3 , The top of the floor 2 forms a wing 20 to which one or more containers, alternatively also unpackaged goods, can be placed, for example for the purpose of transport and storage in an automatic warehouse or in-house logistics. The floor 2 is here on its upwardly facing side with longitudinal and transverse upper ribs 21 educated. About the wing 20 of the soil 2 distributed are several recesses 24 provided, in each of which a resilient stop element 4 is arranged.

The stop elements 4 serve on the carrier 1 attached containers or cargo pieces from slipping on the wing 20 to prevent, even if the wing 20 not completely filled out. The stop elements 4 are resiliently formed for this purpose, wherein they are in an unloaded state, as in 1 represented over the plane of the wing 20 projecting upwards. In this position form the stop elements 4 for between the stop elements 4 standing containers or cargo pieces stops against slipping sideways. For larger on the wing 20 attached containers or cargo pieces are all or part of the stop elements 4 pressed down against their spring force, so that they are flush with the wing 20 are.

2 shows the wearer 1 out 1 in an enlarged, partially vertical sectional view, wherein the sectional plane through one of the stop elements 4 runs. In the foreground the 2 is on the left part of the floor 2 with the through the wing 20 formed top and the top ribs 21 visible, noticeable. In the background is a part of the floor 2 surrounding edge 3 of the carrier 1 visible, noticeable.

At the edge facing the viewer is one of the in a corresponding recess 24 in the ground 2 arranged stop elements 4 visible on average. The stop element 4 is as a leaf spring 40 , here specifically as tongue leaf spring, with a first, clamped end 41 and a second, free end 42 executed. This describes the leaf spring 40 an arcuate course, wherein a vertex portion of the arc an upper element part 43 forms, which cooperating with one or more, not shown attached containers, as anti-slip for this serving part of the stop element 4 forms.

At its first, clamped end 41 owns the leaf spring 40 in the illustrated embodiment, two transverse locking pins 46 of which in 2 only the back is visible. By means of the locking pins 46 is the leaf spring 40 in snap shots 26 in the ground 2 of the carrier 1 are molded, engaged. From the field of locking pins 46 and the rest of the leaf spring 40 away extends a support arm 44 , with his free end at the bottom 2 is supported. The leaf spring 40 can also be different with the ground 2 be connected, for example by welding or gluing, and alternatively also at its two ends to the ground 2 get connected.

The leaf spring 40 consists of a resilient material, preferably plastic, and thus has a self-restoring force to produce the desired spring force. In 2 is the leaf spring 40 shown in an unloaded state, in which the upper element part 43 over the wing 20 of the soil 2 projects upwards. The two ends 41 . 42 the leaf spring 40 but are within the recess 24 in the ground 2 and become in it at their lateral edges 45 through the recess 24 laterally delimiting surface areas 25 of the soil 2 guided and supported. In this position, the leaf spring 40 as a stop element 4 an adjacent container or piece of cargo on slippage on the support surface 20 of the soil 2 prevent.

When loaded from above by an attached, larger-area container or an attached large-scale charge piece is the upper element part 43 under elastic deformation of the leaf spring 40 pressed down until it is flush with the wing 20 lies. In this position, the stop element 4 no stop function, but does not interfere with the placement of containers or cargo pieces on the wing 20 ,

3 shows the wearer 1 out 1 in a partial view obliquely from above together with a single container arranged thereon 5 whose base area is only a fraction of the area of the ground 2 of the carrier 1 occupies. The container 5 is here at one of the corners of the vehicle 1 arranged so that the container 5 on two sides by the edge 3 of the carrier 1 secured in his position. At his other two, from the edge 3 distant sides is the container 5 at the level of its soil by means of one stop element each 4 secured against slipping, like the 3 shows.

The arrangement, distribution and alignment of the stop elements 4 on the ground 2 of the carrier 1 is appropriate depending on the sizes of the base areas of the carrier 1 to be transported container or cargo pieces. As for the arrangement of a stop element 4 in the ground only the matching recess 24 and the means for fixing the stop element 4 , such as the Rastaufnahmen 26 , must be provided, in the manufacture of the carrier 1 its bottom 2 changed with relatively little effort and are manufactured specifically for different applications and purposes.

4 shows the wearer 1 out 1 together with two containers arranged thereon 5 different sized base area, partly in a partial view obliquely from above and partly in a vertical section. Down in 4 is the carrier 1 with his bottom 2 and its outer peripheral edge 3 , The floor 2 is here again with top, longitudinal and transverse ribs 21 educated. In the in 4 right back corner of the carrier 1 is a small container 5 arranged, the container 5 out 3 equivalent. In the in 4 left rear corner of the carrier 1 is a second container 5 arranged, in comparison to the right-hand arranged first container 5 has a larger, for example, twice as large, base area. The two containers 5 are supported in the transverse direction of the 4 seen each other as well as left and right and rear on the circumferential edge 3 of the carrier 1 from.

The right container 5 is also at its front side facing the viewer by the in 4 right in front of the right container 5 arranged stop element 4 secured against slipping in one direction to the front. In this case, the upper element part protrudes 43 this stop element 4 upwards over the wing 20 in front.

This in 4 left-visible stop element 4 is not needed here for a slip protection and is against its spring force by the arranged there larger left container 5 in one with the wing 20 flush position pressed down. When the stopper element 4 forming leaf spring is formed with a correspondingly low spring force, already enough, as in 4 shown, an empty container 5 for a depression of the stop element 4 out.

5 shows the wearer 1 in a second embodiment, in a partial view obliquely from above. For the second embodiment of the carrier 1 is characteristic that here is the soil 2 with a largely continuous, smooth wing 20 is formed and with underside, in 5 invisible ribs is reinforced. All around is also a raised edge 3 intended.

At appropriate positions are in the ground 2 and in its wing 20 recesses 24 attached, in each of which a stop element 4 is arranged in the form of a leaf spring.

In the unloaded state of the stop element 4 its upper element part protrudes 43 over the wing 20 upwards in front. At its lateral edges 45 becomes the stopper element 4 in the recess 24 guided and so protected against twisting or bending when exposed to external forces.

6 shows the wearer 1 out 5 in an enlarged, partially vertical sectional view, wherein the sectional plane through one of the stop elements 4 runs. In the foreground the 6 is the ground 2 with its upper-side wing 20 and with its lower ribs 22 , In the background is a section of the floor 2 bordering peripheral edge 3 visible, noticeable.

The stop element 4 is also inside the soil here 2 in the recess in it 24 arranged and again as an upwardly curved, arcuate tongue leaf spring 40 executed.

At her first, in 6 left end 41 is the leaf spring 40 again by means of here largely hidden locking pins 46 with the ground 2 connected, locked here, and thus mechanically clamped. By means of a here also to the leaf spring 40 molded support arm 44 is the leaf spring 40 on one of the lower, longitudinal and transverse, the floor 2 stiffening ribs 22 supported.

The second, free end 42 the leaf spring 40 has an end bend, with which the leaf spring 40 in their unloaded condition according to 6 at the bottom of the wing 20 of the soil 2 is applied. In this position, the stop element 4 forming leaf spring 40 an attached container or an attached piece of cargo against slipping in the plane of the wing 20 prevent.

If a container or a cargo piece has such a large base area, that this over one or more stop elements 4 extends, the leaf spring 40 in itself against its own restoring force elastically bent down so far that the upper element part 43 then flush with the surface of the wing 20 lies. When the load is removed, the leaf spring 40 back to their unloaded, higher position.

At the side edges 45 also here is the leaf spring 40 to the recess 24 limiting surface areas 25 of the soil 2 laterally guided and supported.

7 finally shows the carrier 1 out 5 in a partial view on its underside. Here are in particular the longitudinal and transverse underside ribs 22 visible to the wing 20 of the soil 2 support. Top right in 7 is a section of the peripheral edge 3 visible from below.

In the ground 2 Here is one of the recesses 24 visible, in the one of the stop elements 4 is arranged. The stop element 4 is, as previously explained, as an arcuate upward curved tongue leaf spring 40 formed and has a first, clamped end 41 and a second, free end 42 , Between the ends 41 . 42 lies the upper element part 43 in the unloaded state through the recess 24 over the top of the wing facing away from the viewer here 20 of the soil 2 projects.

At the first, clamped end 41 the leaf spring 40 are to these two sideways protruding locking pins 46 Molded in the locking seats 26 , which here in one piece to the ground 2 are molded, are engaged. From the tense end 41 the leaf spring 40 extends the support arm 44 down, that is in 7 towards the viewer, and rests on the rib adjacent to it 22 from.

As the 7 illustrated, is sufficient in the production of the carrier 1 a very simple, easily automatable engagement of the leaf springs 40 to form the stop elements 4 , In addition, the leaf spring 40 can be easily manufactured as a one-piece injection-molded part, as shown in the drawing, or alternatively as a one-piece metal part or as a plastic-metal composite part, which allows cost-effective mass production in each embodiment.
