Abstract
Description
Technical Field
[0001] The invention relates to a frame for a pallet, the frame can be placed on the pallet and goods can be placed in the frame for transportation. The invention particularly relates to a support element on a corner of the frame, particularly a support element with adjustable height. Background Art
[0002] The frame for a pallet usually consists of four corner supports arranged in the corners of the pallet and struts connecting the upper ends of the supports. The struts can be arranged in a rectangular shape or cross-shaped by connecting the upper ends of the supports diagonally. Such a frame makes it possible to place goods on the pallet and such a frame can be stacked. In this case, the supports can have a fixed height or can also be height-adjustable.
[0003] A pallet frame is known, for example, from WO 2020 / 061626. Such a pallet frame has four support elements mounted on the pallet, the upper ends of which are connected to diagonally arranged struts. The struts can be telescopically extended by having an inner support element surrounded by an outer support element and being movable in and out of the outer support element. Both support elements have a plurality of holes distributed over their length, into which pins are inserted to fix the length achieved by the support elements.
[0004] JP2001-18648 discloses another frame for a pallet, which also has a length-adjustable support element with a telescopic design and a fixing pin. The upper end of the support element is connected to a rectangularly arranged cross brace. Horizontal reinforcement struts also connect the support element at a partial height. Summary of the invention
[0005] The object of the present invention is to provide a frame for a pallet and for holding inserts for goods, the height of which frame can be adjusted in a simple manner.
[0006] The frame for the pallet and for accommodating the insert for the goods has four supports, each of which comprises a foot at its lower end and a head at its upper end, wherein the heads of the supports are respectively fixed to the frame. The four supports are divided into at least two parts and each comprises an upper element and a lower element, which are connected to each other in a pivoting manner by means of a hinge. The upper element comprises the head of the support and extends downwardly from the head to the lower end of the upper element, wherein the head is fixed to the frame. The lower element comprises the foot of the support and extends upwardly from the foot on the one hand to the lower end of the upper element and on the other hand to the hinge.
[0007] The frame comprises four horizontally extending sides which form a rectangular perimeter, wherein the support is fixed to the corners of the rectangle. The lower element and the upper element can be pivotally moved towards and away from each other by means of hinges. In a first position, the upper element and the lower element of the support are moved towards each other by means of the hinges, so that the mutually facing faces of the upper element and the lower element are in contact with each other and the support has a maximum height. In a second position, the lower element is pivoted away from the upper element in the horizontal direction and moves towards the frame, i.e. towards the horizontally extending and perimeter-forming sides of the frame, whereby the support has a smaller height in this second position and thus forms a partial height.
[0008] The four supports can be adjusted to two different heights by means of two hinged elements. In a first position (hereinafter referred to as the closed position), the lower element is moved towards the upper element so that the mutually facing surfaces of the two elements are in contact with each other. In this position, the two elements form a support with full height. In a second position (hereinafter referred to as the open or unfolded position), the lower element is moved away from the upper element at 90° or nearly 90° and pivoted towards the frame similar to a flap, so that the partial height of the support is equal to the height of the upper element.
[0009] The height adjustment of the supports makes it possible to transport goods of different sizes by means of inserts which can be detachably fixed in the frame in various ways, so that, depending on the size of the goods, inserts of different depths and inserts with different division schemes can be fixed.
[0010] The frame can be equipped with an insert made of fabric, synthetic material or other material (eg cardboard or metal), which has, for example, a plurality of partitioning options.
[0011] In one embodiment of the frame according to the invention, the insert for receiving goods can be detachably fastened to the frame.
[0012] In one embodiment, the insert is made of synthetic material, wherein the inner side of the frame has a protrusion, on which the insert is fixed in the frame. Such an insert can be removed from the frame again or replaced by another insert, for example with a different depth.
[0013] In certain embodiments, the insert comprises a thermoformed component.
[0014] In another embodiment, the frame has elements on which the plug-in can be fixed or hung. For example, these elements can be hooks, connecting plates or buttons.
[0015] In another embodiment, the frame has an insert made of a fabric material and is adhesively fixed to the frame or welded to the frame. The fabric insert has flexibility and can be used for full-height and partial-height supports.
[0016] Goods can be transported in the compartments of inserts of appropriate size and depth. If the goods are larger or more numerous, the frame can be used with supports of full height and inserts of great depth can be fixed in them. If the goods are smaller or fewer in number, the height of the supports can be lowered and inserts of less depth can be fixed on the frame.
[0017] The particular advantage of the present invention is that partial heights of the support can be realized simply, easily and quickly. For adjusting the height, no auxiliary mechanisms, tools or other loose elements are required to fix the selected support height.
[0018] The frame according to the present invention with height-adjustable supports can either be directly stacked one on top of the other, or be placed on any pallet by forming a placement portion along the periphery of the pallet. Here, required support height can be set in the stack according to application.
[0019] For example, when a partial height is provided, a plurality of frames of this type can be stacked and transported, wherein the total volume of the stack, for example for empty transport, is significantly smaller than a stack of frames of full height with supports.
[0020] In one embodiment of the invention, the axis of the hinge extends parallel to one side of the frame, i.e. parallel to the short side or the long side of the rectangular frame. This allows the lower element of the support to move under the frame parallel to the frame, thereby remaining within the perimeter of the rectangular frame and not outside or inside the frame.
[0021] In one embodiment of the invention, the hinge is arranged in the upper region of the upper element of the support. In this arrangement, the hinge is close to the frame. Thus, when the lower element leaves the upper element and pivots upwards, the lower element is in a horizontal position close to the frame and can be fixed there by suitable means.
[0022] In a modification of the present invention, the hinge is arranged at any position on the upper element of the support. Here, the lower element is pivoted upwards towards the direction of the frame by 90 ° or more.
[0023] In one embodiment of the invention, the mutually facing faces of the lower and upper elements extend at an angle to the vertical. Thus, the above-mentioned faces of the upper and lower elements, which touch each other at the full height of the support, extend obliquely with respect to the vertical. The inclined faces provide an optimal stability for both the upper and lower elements, since this makes the upper element as wide as possible in its upper region and the lower element in its lower region. The weight of the pallet is optimally distributed through the force transmission of the two elements of the support, so that the two elements of the support carry the load in an optimal manner and remain stable for a longer time. In addition, this design also relieves the hinges.
[0024] In a variant, the mutually facing surfaces of the lower element and the upper element are horizontal or vertical. This variant is not as stable as the above embodiment, but it is also a feasible option.
[0025] In one embodiment of the invention, the upper and lower elements of each support can be connected to one another in the closed position by means of a detachable snap connection. The snap connection enables the lower element to be fixed to the upper element when the lower and upper elements are joined together by pivoting and the support has its full height. The detachable snap connection enables the lower element to be easily detached again and pivoted outwards again to reach a partial height of the support.
[0026] In one embodiment of the present invention, the frame has a notch in each corner on its upper side. These notches are used to fix the position of another frame stacked thereon.
[0027] In another embodiment of the invention, the foot of each support, i.e. the lower end of the lower element, has a downwardly directed protrusion. The protrusion is used to be fixed to the support plate or another frame arranged below. The shape of the protrusion can be inserted into a corresponding recess in the support plate or another frame below, so that the frame with four support elements can be stopped on the support plate or another frame below.
[0028] In another embodiment of the invention, the lower end of the upper element also has a downward protrusion. Similar to the protrusion on the lower element mentioned above, the shape of the protrusion can be inserted into a corresponding recess in the support plate or another frame below. This makes it possible to stop the frame with four supports at a partial height on the support plate or another frame.
[0029] In a particular embodiment of the invention, the projection on the lower end of the lower element, i.e. the foot of the support, has a right-angled cross section. Such a projection can be inserted into a correspondingly shaped recess of a right angle at the corner of the frame or the pallet and stop there.
[0030] In one embodiment of the invention, the projection on the lower end of the upper element has an edge. The edge can be used for a detachable snap connection between the upper element and the lower element in the closed position, for example by locking the barb on the lower end of the upper element on the edge.
[0031] In one embodiment of the invention, the lower element comprises not only one part, but two parts, which are each pivotally connected to the upper element by means of a hinge. Two hinges are placed on both sides of the upper element, i.e. one hinge on one side of the upper element and the other hinge on the opposite side of the upper element. This enables the two parts of the lower element to be pivoted upwards towards the frame, respectively, on one side of the upper element. In order to adjust the height of the support to the partial height, the two parts of the lower element are each pivoted at their hinges away from the upper element and parallel to the frame and brought into a position parallel to the frame.
[0032] In a first variant of this embodiment, the two parts of the lower element are here realized with the same length.
[0033] In a second variation of this embodiment, the first and second parts of the lower element are implemented to have unequal lengths. This variation implements another height adjustment scheme for the support, so that the support can be adjusted to a total of three different heights. In the first adjustment scheme, the support occupies its full height, wherein the lower element is vertically erected and the two parts of the lower element are not pivoted out, that is, in a closed position and vertically erected. In the second adjustment scheme, the support has a first part height, wherein the first part of the two parts of the lower element is pivoted out, that is, in an unfolded position. Here, the second part of the lower element is still in a closed position and is vertically erected. The height of the support is determined in this first part height by the second part of the upper element and the lower element. In the third height adjustment scheme, the first and second parts of the lower element are both pivoted away from the upper element, whereby the support occupies the second part height. In this adjustment scheme, the second part height of the support reaches a height equal to the height of the upper element.
[0034] In another embodiment, one or both parts of the lower element can be fixed to the underside of the frame in its pivoted position, with the hinge open. For example, the parts of the lower element can be fixed by means of a detachable snap connection. Any other fixing solutions are conceivable.
[0035] One or more stacks of a plurality of frames according to the invention can be easily placed in a foldable pallet container or on a pallet with surrounding side walls made of hollow sheet metal placed on the pallet. In this case, the support elements of the frame are present at full height or folded at partial height. The placement of the stack of frames in the mentioned containers or side walls enables efficient and protected transport of goods. The pallet container and the side walls made of hollow sheet metal can be covered in a closed manner with a cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 A frame 1 according to the invention is shown, which has four supports 2 which can be placed on a pallet P and in which inserts 3 for goods are arranged. The supports 2 extend from a foot 4 to a head 5 which is fixed to the frame 1. Figure 2a to Figure 2c As shown, the support 2 has an upper element 6 and a lower element 7 which are pivotably connected to one another and serve for height adjustment of the support 2 .
[0053] Figure 2aTwo supports 2 of a frame 1 are shown, which are shown in different positions. In one of the supports (shown on the left), an upper element 6 and a lower element 7 are joined together in such a way that the faces 6a and 7a facing each other are in contact with each other. The faces form a closed position in which the two elements stand vertically. In the other support (shown on the right), the lower element 7 is pivoted from the upper element 6, parallel to the frame 1 and towards the frame by a hinge 8. The faces 6a and 7a of the upper element 6 and the lower element 7 are respectively shaped complementarily so that when the hinge 8 is closed and the lower element 7 is in the vertical position, the faces are in contact with each other.
[0054] Figure 2b and Figure 2c Shown in detail Figure 2a The support member, wherein Figure 2b represents the support shown on the right, Figure 2c The figure shows the hinge 8 and the two elements 6 and 7, respectively, in Figure 2c In the example, elements 6 and 7 are combined and Figure 2b The lower element 7 is moved away from the upper element 6 and is in a pivoted out position. The lower element 7 can be pivoted away from the upper element at the hinge 8 in the direction of the arrow and into a horizontal position in which it extends parallel to the frame 1, as shown in FIG. Figure 3 To this end, the axis 8 ′ of the hinge 8 extends parallel to one side of the frame 1 , in this example, parallel to the long side 1 ′ of the frame.
[0055] The mutually facing faces 6a, 7a of the upper element 6 and the lower element 7, i.e. the face 6a of the upper element 6 and the face 7a of the lower element 7, extend at an angle to the vertical in the example shown. The lower element 7 on the one hand extends upwards from the foot 4 of the support at part of the height to the lower end of the upper element 6. The face 7a of the lower element 7 extends further from there to the hinge 8. The face 6a of the upper element also extends obliquely downwards from the hinge 8 to the lower end of the upper element 6, which, as mentioned above, optimizes the force transmission and relieves the load on the hinge.
[0056] Figure 2b and Figure 2c Also shown is the design of the lower ends of the two elements 6 and 7. Figure 2c and Figure 2b As shown, the foot 4 of the support element 2 has a projection 9 which can be placed in a depression in the pallet or in the upper side of a corner of the frame 1. A corresponding depression 10 is shown in the frame 1 in all the figures. Figure 7Also shown is a pallet P in which corresponding recesses 11 are arranged in the corners of the pallet P and on which the supports of the frames can rest. The protrusions 9 on the supports and the recesses 10 and 11 in the frames or pallet serve to stop the frames when a plurality of frames are stacked or placed on the pallet.
[0057] The lower end of the upper element 6 also has a protrusion 12, such as Figure 2a , Figure 2b and Figure 2c The projection 12 also serves to place the support element 2 at a reduced height, i.e. at a partial height, on a frame or a pallet by placing the projection 12 in a corresponding recess. In addition, the projection 12 serves to detachably fasten the lower element 7 to the upper element 6 in the closed position by means of a snap connection 13. For this purpose, the lower element 7 has a barb 14 which can snap onto an edge 15 on the projection 12.
[0058] If the height of all four supports 2 is adjusted in such a way that in each support 2 the lower element 7 is pivoted away from the upper element 6 and into a horizontal position, the frame 1 acquires a partial height of the height of the upper element 6 and can be used in this shortened form, for example, to be placed on a pallet. This shortened form of the frame 1 is Figure 3 , Figure 4a and Figure 4b . The upper element 6 stands with its lower end on the pallet P, while the lower element 7 is pivoted out and extends parallel to the frame. In this example, the lower element 7 is pivoted in each case within a short side 1″ of the frame 1. In the unfolded position, the insert 3 with a smaller depth can be used to transport goods of corresponding size. In this position, empty transport of the frame with a smaller overall volume is also possible.
[0059] Figure 4a and Figure 4b In another section, the frame 1 according to the invention is shown, in particular the fastening of the shortened support 2 and the insert 3 to the frame 1. The upper element 6 of the support is fastened to the head 5 of the support 2 on the underside of the frame 1 by means of a snap connection 16. The insert 3, which is made of fabric, for example, is fastened to the frame 1 by welding.
[0060] Figure 4a and Figure 4b Also shown is the solution of placing the shortened support 2 in the pallet by inserting the protrusion 12 into the recess 11 at the lower end of the upper element 6 .
[0061] Figure 5 and Figure 6A variant of the frame 1 according to the invention is shown in which the lower element 7 of the support 2 is respectively composed of two parts 20, 21. Both parts 20 and 21 are pivotally connected to the upper element 6 by hinges and can be moved away from the upper element 6 and into a horizontal position, and again into a vertical position and joined to the upper element.
[0062] Figure 5 A variant is shown in which the parts 20 and 21 are in a closed position in which they are joined together with the upper element 6. The support 2 has here its complete full height. Figure 6 A variant with a shortened support element is shown, in which the parts 20 and 21 are each pivoted laterally, in each case in opposite directions, away from the upper element 6. The first part 20 of the lower element 7 is moved toward the long side 1' of the frame 1, while the second part 21 of the lower element 7 is moved toward the short side 1" of the frame 1, so that both parts extend parallel to the frame 1. The upper element 6 is placed in the recess of the pallet P by means of a projection on its lower end.
[0063] exist Figure 5 and Figure 6 In the embodiment of the present invention, the parts 20 and 21 of the lower element 7 are respectively designed to have the same height.
[0064] In all variants, the pivoted lower element 7 can be fixed in its horizontal position on the underside of the frame 1. This facilitates handling of the frame when the height of the support 2 is changed. For example, detachable snap connections and connections by means of connecting plates or other fixing mechanisms are suitable for fixing. This applies to both one-piece and two-piece lower elements.
[0065] exist Figure 5 and Figure 6 In another variant of the example, the parts 20 and 21 of the lower element can also have different heights. In order to adjust the height of the support from the full maximum height to the shortened first height, the first part of the lower element is pivoted out, while the second part of the lower element remains vertical. The support then stands on the lower end of the second part of the lower element.
[0066] For further adjustment of the height of the support from such a partial height to a smaller height, the second part of the lower element will also be pivoted out so that only the upper element stands vertically and the support stands on the lower end of the upper element, such as Figure 6 and Figure 3 shown.
[0067] exist Figure 8 and Fig. 9, two stacks 30, 31 of frames 1 according to the invention are shown standing side by side, each having a three-part support, wherein in the stack 30 on the left, the frame 1 is arranged to a partial height of the support, which is the same as the height of the upper element 6, and in the stack 31 on the right, the support of the frame 1 occupies its full maximum height, which is equal to the height of the upper element 6 together with the two parts of the lower element 7.
[0068] In the stack on the left, six frames with short inserts are shown, while in the stack on the right, three frames with long inserts are stacked. It is also shown how a stack with supports set at a partial height enables empty transport of such reduced-volume frames.
[0069] Fig.10a Show according to Figure 8 and Fig. 9 30 and 31 of frames 1 according to the invention, in which the stacks 30, 31 stand on a pallet P and are surrounded by vertically standing side walls made of cavity plates 40. This packaging system is also known in specialist shops under the term "sleeve packing". The cavity plates 40 are covered by a cover plate 41, which rests on the upper edge of the cavity plates 40 and on the uppermost frame 1 of the stack 31. In the stack 30 of frames 1, the frames are each at a reduced height, wherein the support parts 20 and 21 of the lower element 7 are folded up. In the stack 31 on the right, the support parts are at full height.
[0070] Fig.10b Shown with Figure 8 and Fig. 9 1 , which is a side view of two stacks 30 and 31 of the same frame 1 according to the invention, wherein the stacks are arranged in this application in a pallet container 50. The pallet container 50 is covered by a cover 51. The pallet container has, for example, deployable side walls 52, which stand on a base of a pallet 53.
