Description

The invention relates to a load carrier for receiving cargo, comprising a base frame with a number of support and / or corner elements and a plate member which is connected to the base frame connected to this or connected.

Charge carriers for receiving cargo are known in the art. These each comprise a base frame made of metal, which has an outer frame, a number of cross braces within this and in its corners corner elements which are post-shaped. The base frame is designed for moving in particular by a forklift and accordingly constructed similar to a pallet with respect to its frame part. The base frame is provided with a steel plate for covering the cross braces within the frame part. The steel plate is provided with a number of openings, can be introduced into the receiving devices for receiving cargo or applied to the steel plate. Due to the use of a metal base frame with a steel plate applied thereon, a weight of the entire prior art load carrier of, in particular, about 111 kg results, with the base alone alone weighing in particular about 82 kg.

The high weight of such carriers of the prior art proves to be disadvantageous in the transport of the load carriers in trucks, as a result of weight and due to the maximum payload of such a truck maximum 78 Load carriers can be transported. In particular, when the respective cargo to be transported on the load carriers has larger dimensions than heretofore, for example instead of 3 Cargo goods only 2 Cargo goods are transported per load carrier. Thus, the number of maximum transportable cargo per truck to 1 / 3 reduced. Conversely, this means that more trucks must be moved to transport the same amount of cargo on the road, which on the one hand leads to increased transport costs, on the other hand, to a greater environmental impact and possibly a larger congestion problem on motorways and federal highways and highways. It would therefore be desirable to develop a charge carrier for receiving cargo in such a way that a weight saving and / or the entrainment of a larger number of cargo on a truck is possible.

The present invention is therefore the object of a charge carrier according to the preamble of claim 1 to the effect that this has a lower weight compared to the prior art in order to transport a larger number of carriers on a truck can.

The object is achieved for a charge carrier according to the preamble of claim 1, characterized in that at least one plate element and at least one base frame are provided, wherein the at least one plate element consists of at least one plastic material and the at least one base frame of at least one metal and / or a metal alloy , Further developments of the invention are defined in the dependent claims.

As a result, a charge carrier is provided for receiving cargo, which comprises at least one base frame of at least one metal and / or metal alloy and at least one plate element of at least one plastic material. The base frame of metal and / or a metal alloy has a number of support and / or corner elements, which protrude from the plane of the base frame or the plane in which the base frame is provided with the plate member. The support and / or corner elements serve to create a distance between stacked charge carriers in order to be able to safely transport the cargo to be picked up on the load carriers. Several charge carriers can be stacked corresponding to each other, wherein each of the charge carriers in the region of their support and / or corner elements stand on each other. By using the at least one plate element of at least one plastic material, a significant weight reduction can be achieved compared to the solutions of the prior art, in which a steel plate is used. This makes it possible to transport a larger number of charge carriers and accordingly on these superimposed cargo in a truck, compared to the possible number of charge carriers with charge material of the prior art accommodated thereon. On the one hand, this leads to a better utilization of the cargo space of a truck by using the charge carriers according to the invention, since this without having exceeded the maximum payload due to the lower compared to the charge carriers of the prior art weight of the present charge carriers a higher number of charge carriers can absorb it recorded cargo. Accordingly, a smaller number of trucks can transport an equal number of charge carriers with charge material received thereon, each in comparison with the prior art charge carriers made entirely of metal. On the one hand, this leads to lower transport costs and, on the other hand a more environmentally friendly transport of goods by road.

The at least one plate element may be formed in one piece. Accordingly, in particular in the region between four support and / or corner elements of the base frame, such a one-piece plate element can be arranged. It is also possible to form the at least one plate element in several parts, in particular in two parts. The production of such a plate element from at least one plastic material can be facilitated thereby, since the respective plate elements have smaller dimensions than in the one-piece formation. In particular, it is possible to manufacture identical parts during the two-part or multi-part forming of the at least one plate element and to place them mutually joined by 180 °. In this case, it proves to be particularly advantageous to form the individual plate element parts on at least one outer edge in a tooth-like manner in front and back to interengage the adjacent plate element parts. The plate element parts thus interlock in the region of their toothing, so that an unintentional displacement of the plate element parts relative to one another can thereby be prevented. Although it is basically not necessary that the base frame has cross braces. Rather, it is basically sufficient to provide a peripheral frame element, on which the at least one plate element is attached to the edge. When providing a plurality of parts of the at least one plate element, however, it is possible to provide a cross-bracing within the frame element of the base frame in the region of the edge-side meshing of the individual plate element parts. On this cross brace, the plate member parts can rest and be attached to this, to allow a particularly secure hold of at least one plate member or its plate member parts on the base frame and a particularly stable configuration of the transition from a plate member part to the adjacent plate member part.

In particular, it proves to be advantageous to releasably secure the plate member on the base frame, on the one hand to allow replacement of the plate member, for example, with wear, on the other hand to allow the plate elements on the one hand and the base frames on the other hand zuzuliefern a final assembly station and only there the final assembly of To provide charge carriers by attaching the plate elements on the base frames. This makes it possible to transport a large number of plate elements separately from the base frames to the final assembly station, which also increases the efficiency and at the same time can reduce the transport costs.

It proves to be further advantageous if the plate element is provided over its areal extent with a number of openings transversely thereto for fastening at least one receiving device thereon for receiving the at least one cargo. The openings in the single-part or multi-part plate element can be distributed substantially uniformly over the planar extension of the plate element, in particular in the manner of a hole pattern. Accordingly, the at least one plate element can in principle be formed as a perforated plate or as a perforated plate member, advantageously no or only a few openings or holes are provided in the outer edge region to a stable resting on the frame member of the base frame and a secure Attach the at least one plate member to allow this. When a multi-part plate element is provided, openings can also be provided throughout in the region in which the individual plate element parts intermesh and also in this edge region of the plate element parts, so that the hole pattern is uniformly provided over the entire plate element and only the regions of the plate element parts , Which rest on the frame member of the base frame, that are arranged between the arranged in the corners of the base support and / or corner elements are formed without the hole pattern. There are advantageously provided only openings for securing the plate member parts on the frame member of the base frame.

The at least one single- or multi-part plate element can furthermore be provided with at least one depression and / or recess and / or recess for arranging at least one receiving device for cargo in a position recessed with respect to the plane of the surrounding surface of the at least one plate element. The cargo can be shaped unevenly, as is the case, for example, with converter bells of transmissions or transmissions. It may prove useful to provide such recesses or recesses or recesses in the at least one single or multi-part plate member to compensate for a difference in height. Especially in the region of such a depression or recess, at least one receiving device for receiving the at least one load or a portion thereof can be arranged on the plate element and fastened there. A fastening of the receiving means on the at least one single or multi-part plate member is further advantageously carried by releasable fastening means, such as screws. For individually cutting a thread in the corresponding openings provided over the flat extension of the plate member are provided away, for example, self-tapping screws can be used. Accordingly, it proves to be advantageous to provide or use at least one self-tapping screw as fastening means for fastening the plate element to the base frame and / or the at least one receiving device on the plate element.

By providing releasable fastening means, it is possible at any time to solve this and to position the receiving devices in other positioning and / or other receiving devices on the respective plate member or the plate member parts and there also releasably secure in the new positioning. Thus, a problem-free adaptation of the charge carrier to different cargo is quickly and easily possible at any time.

For automated handling of the charge carrier, at least one positioning device can be provided. This can be formed in particular in the form of at least one positioning opening in the plate element. When providing, for example, a two-part plate element, two such positioning openings can be provided at the correspondingly desired positions for the automated handling of the charge carrier, for example by robots.

Further advantageously, the plate element may be provided in the region of the at least one corner element of the base frame with at least one notch and / or recess for engagement with the at least one corner element. The provision of such a notch and / or recess proves to be advantageous over the provision of an opening through which the corner element is inserted or the plate element is plugged onto the corner elements, as a tolerance compensation of manufacturing tolerances on the part of the plate member and also on the part of the base frame easily possible. Also, changes in the dimensions of both the plate member and the base frame at extremely high and extremely low ambient temperatures are easily compensated for by providing such notches or recesses in the edge region of the respective plate member. A tension-free grip of the at least one plate element to the at least one base frame of the load carrier is thus possible at any time.

For example, a charge carrier may have four support and / or corner elements that may be pillar-shaped and, for example, one or more plate element parts that form the plate element disposed between these four support and / or corner elements. It is also possible to arrange a plurality of single or multi-part plate elements in one or more base frame (s), wherein the base frame not only has four outside, arranged in the four corners of the base corner elements, but more support elements, between the outside corner elements are arranged. The latter can also be provided in the area of several mutually joined plate elements or several plate element parts. On such larger-sized charge carriers, for example, more cargo or containers can be arranged with several cargo received therein than with smaller sized carriers with only a single or multi-piece plate member and four support and / or corner elements, which are each arranged in the corners of the base frame , is possible.

For further explanation of the invention embodiments of this will be described in more detail below with reference to the drawings. These show in:

• 1 a perspective view of a first embodiment of a charge carrier according to the invention with a base frame according to the invention and a two-part plate element according to the invention,
• 2 a perspective bottom view of the charge carrier according to the invention 1 , and
• 3 a perspective view of a charge carrier according to the invention with thereon exemplified aufgebeten receiving devices for receiving cargo.

1 shows a perspective top view and 2 a perspective bottom view of a carrier 1 for receiving cargo. The charge carrier 1 includes a base frame for this purpose 2 that with a two-piece plate element 3 is provided. The base frame 2 has a circumferential frame element 20 on. This is in the corner areas 21 . 22 . 23 . 24 each with a post-shaped corner element 25 Mistake. The post-shaped corner elements 25 at the same time serve as support elements to one on the base frame 2 supported additional base frame to support, so to be able to stack charge carriers on top of each other. These are each in the area of the post-shaped corner elements 25 the base frames placed on each other. Accordingly, the post-shaped corner elements 25 in each case a projecting end base section 26 on, like 1 and 2 can be removed. With these projecting end-side foot sections 26 When stacking the bases on top of each other, the next stacked base frame 2 on the Post-shaped corner elements 25 of the illustrated base frame 2 established. A slipping of the stacked bases against each other can by the cantilever base sections 26 of the corner elements 25 be prevented accordingly. In particular, the projecting pedestal sections 26 be formed on its underside so that they all sides have a circumferential edge 126 have (see 2 ), the lateral displacement of therein received ends of the corner elements 25 prevented.

Furthermore, the base frame 2 in the in 1 and 2 shown embodiment on two opposite sides of a reinforcement by providing a parallel to the arranged there circulating frame member 20 extending side strut 27 , over two each in the area of the post-shaped corner elements 25 arranged spacer supports 28 and another spacer support disposed therebetween 29 with the surrounding frame element 20 are connected. This embodiment of the two opposite sides of the base frame 2 serves to better engage the forks of a forklift truck for transporting the load carrier 1 For example, in a truck and out of this to a point of use of the cargo in, for example, a production hall or for example a warehouse.

The base frame 2 consists of a metal and / or a metal alloy, for example steel. The plate element or the plate element 30 . 31 consists / consist of at least one plastic material. Possibly. For example, areas to be reinforced may be made of a more stable plastic material than the remaining areas of the panel member 3 consist.

On the surrounding frame element 20 of the base frame 2 is the two-piece plate element 3 detachable. An attachment via releasable fastening means, such as screws 4 , which can be designed in particular as self-tapping screws. The two-piece plate element 3 consists of two identically designed plate element parts 30 . 31 , which are joined together by 180 ° offset. The plate element parts 30 . 31 each have a large number of evenly distributed arranged or largely uniformly distributed openings arranged 32 on, approximately perpendicular to the planar extension of the plate element parts 30 . 31 are formed. These openings 32 serve to fasten receptacles 5 for picking up cargo. Examples of such recording devices 5 are in 3 indicated. Such receiving devices can be designed, for example, in the form of cushions and / or stop elements and / or dividing elements. On these recording devices 5 is subsequently the respective cargo, such as converter bells, gear etc. aufgefügt and transported on it. To the greatest possible variability of the arrangement of the respective recording devices 5 on the plate element 3 to have are the number of substantially regularly arranged openings 32 in this or here two plate element parts 30 . 31 intended. Accordingly, not only the recording devices 5 be formed arbitrarily, but also on the plate element parts 30 . 31 of the plate element 3 Arranged at any position, there at any time be resolved again and placed elsewhere or exchanged for others.

In particular 1 can be further removed, have the two plate element parts 30 . 31 along a border area 33 respectively. 34 tooth-shaped projections 35 . 37 and returns 36 . 38 on. The projections and recesses of the two plate element parts 30 . 31 each interlock, so that the respective projection 35 of the border area 33 of the plate element part 30 in the return 38 of the border area 34 of the plate element part 31 engages and the respective lead 37 at the edge 34 of the plate element part 31 in the respective return 36 of the border area 33 of the plate element part 30 intervenes. The two plate element parts 30 . 31 are thus along their edge areas 33 . 34 interlocked so that they hold together against slipping together and thus a stable unit of the two-piece plate element 3 can also be created there. At the in 1 embodiment shown are along the edge regions 33 . 34 the two plate element parts 30 . 31 also connections with a cross strut 120 of the base frame 2 provided, the transverse strut 120 in the bottom view of the load carrier 1 in 2 you can see. screw 39 are in 1 as releasable fastening means along the two edge regions 33 . 34 the two plate element parts 30 . 31 for attaching these to the cross brace 120 shown. Such a crossbar 120 extending across the surrounding frame element 20 of the base frame 2 extends approximately parallel to two side struts 121 . 122 of the circumferential frame element 20 and approximately perpendicular to the other two side struts 123 . 124 from this, can also be omitted depending on the design of the base frame.

The two plate element parts 30 . 31 are also with two recessed sections 130 . 131 Mistake. These are in the in 1 embodiment shown approximately rectangular and serve to accommodate areas of the cargo to be transported on the carrier 1, which optionally have a greater height extent than the height extension of the post-shaped corner elements 25 correspond. Without the provision of such recess portions 130 . 131 in the two plate element parts 30 . 31 would possibly be a stacking of several bases 2 or charge carrier 1 on top of each other not or only badly possible. For cargo that does not require such recessed portions in the surface of the plate member 3 provide, the recessed sections 130 . 131 be covered by appropriately trained cover plates, if this proves to be useful. On the recessed sections 130 . 131 otherwise any recording devices 5 be attached or arranged. Also the depression sections 130 . 131 are accordingly each provided with a number of openings, which are used to attach the receiving devices 5 by fasteners, such as screws 4 , can be used.

The two plate element parts 30 . 31 also have two positioning holes 132 . 133 on. The positioning openings are used for automated handling of the load carrier 1, for example by robots, in order to hold these defined receiving points or defined receiving openings or positioning openings. Accordingly, the positioning holes 132 . 133 in the two plate element parts 30 . 31 be positioned at predetermined locations.

The two plate element parts 30 . 31 also have in the area of the post-shaped corner elements 25 one recess each 134 . 135 . 136 . 137 on. These recesses 134 to 137 embrace the post-shaped corner elements 25 , This makes it possible to manufacture tolerances on the part of the plate element parts 30 . 31 However, also on the part of the base frame can easily compensate. Even with temperature fluctuations of the ambient temperature is thus always a safe and verklemmungsfreier hold the plate member parts 30 . 31 on the base frame 2 possible.

As 1 can also be removed, are circumferentially about the two-piece plate element 3 no openings 32 provided, but only a few mounting holes 138 for securing the plate member parts 30 . 31 on the circumferential frame element 20 of the base frame 2 ,

Both the openings 32 as well as the mounting holes 138 can be inserted without any thread in the manufacture of the plate element parts in this. A thread cut is then made in each case by using in particular self-tapping screws as fastening means for fastening the plate element parts 30 . 31 on the circulating frame element 20 of the base frame 2 or the recording devices 5 on the plate element parts 30 . 31 of the plate element 3 , This makes it possible, the plate element parts 30 . 31 to produce as cheaply as possible. Furthermore, any change is in particular the arrangement of the receiving device 5 on the plate element parts 30 . 31 at any time by loosening the screws 4 and repositioning the receiving devices 5 on the plate element parts 30 . 31 possible.

By using the plate element parts 30 . 31 made of plastic material in combination with the base frame made of metal, such as steel, a significant weight saving is possible compared to the use of steel plates in a steel base frame, which can be in particular 30 kg per carrier 1.

In addition to those in the 1 and 2 shown embodiments of the charge carriers 1 In addition to those in the four corners of the base frame 2 arranged corner elements 25 between these and also in the surface of the plate element parts 30 . 31 or several plate elements 3 further post-shaped support elements are arranged to increase the extension of the charge carrier. As a result, larger or more cargo can be added to this. For example, it is also possible to use a plurality of charge carriers, such as those in 1 and 2 3 and 3 are joined together to form a larger sized carrier. Here, a wide variety of connecting means for connecting the charge carriers in the region of the base frames and / or the plate elements 3 or plate element parts are selected. Furthermore, not only the cargo itself, but also containers with it can be applied or placed on the plate elements.

In addition to the above-described and in the embodiments mentioned charge carriers for receiving cargo, comprising a base frame with a number of support and / or corner elements and a plate member which is connected to the base frame with these connected or connected, numerous other can be formed in which in each case at least one plate element is provided from at least one plastic material and the base frame consists of at least one metal and / or at least one metal alloy.
