The present invention concerns a pallet station (1). The pallet station (1) comprises a storage surface in the form of a shelf (5). The shelf (5) is received on support beams (4) arranged between transversal beams (3). Support rails (6) are attached to the shelf (5) by means of hook elements (14, 16). The hook elements (14, 16) used for attaching the support rails (6) are beam hooks (14) and/or net hooks (16).
This application is a National Stage Application of PCT/EP2014/053276, filed 20 Feb. 2014, which application is incorporated herein by reference. To the extent appropriate, a claim of priority is made to the above disclosed application.
The present invention concerns a pallet station normally forming a part of a storage rack. It is mainly directed to releasable fastening of support rails on a shelf of the pallet station.
In many stores there are storage racks for self-picking, i.e. the customers are to pick-up goods to be bought directly from the storage rack. Often the customers may only pick-up goods from lower levels, while the storage rack as such may have several higher levels. In some instances the goods to be placed in the storage rack is placed on some kind of load carrier, such as loading ledges or different kinds of pallets. The load carriers are normally received on some kind of support rails on the shelves. In other instances the goods is placed directly on the shelf, without any load carrier. For goods not placed on load carriers the support rails are normally to be removed, as they may damage the goods in that they protrude above the shelf as such.
For safety reasons the shelves of a storage rack are often made in the form of nets. By using nets the shelves will not unnecessarily hinder for instance water from sprinklers. Thus, using nets is positive in view of fire-safety. The nets will also hinder parts from dropping through. Furthermore, there should be means to hinder that the storage rack falls down when people are placing or picking gods onto or from the rack.
The invention is directed to a pallet station having a shelf, on which shelf support rails are to be attached. The pallet station is often one of several similar stations forming a storage rack.
Even though the present invention has been developed for use in storage racks, a person skilled in the art realises that it can be used also for other purposes. One example is a display surface in a store.
The support rails are to receive loading ledges, pallets etc. Furthermore, the support rails are to be attached to the shelf of the pallet station in such a way that they are released, if exposed to extensive forces.
Depending on the goods to be received on the pallet station the support rails may or may not be needed. Thus, it is beneficial if the support rails can be mounted and dismounted in a relatively easy and quick way. Thereby, the pallet station can be adapted to the actual need at any given time. The support rails may be mounted releasable on only lower levels of a support rack formed of several pallet stations. In some instances the support rails at higher levels are also mounted in a releasable way. In this context lower level is under about 1.80 m.
In the description below the shelves are shown as having the form of nets, but a person skilled in the art realizes that the shelves can have any form as long as they have openings for receiving the hook elements used for attaching support rails. For ease of description the shelves are shown as nets here. Nets are normally the preferred form of the shelves.
Further objects and advantages of the present invention will be obvious to a person skilled in the art reading the detailed description below.

As used in this description the expressions “horizontal”, “vertical” and similar expressions are in view of the normal use of the parts described, and as normally shown in the enclosed drawings.
In FIG. 1 a pallet station 1 is shown. The pallet station 1 is a part of a storage rack. It comprises vertical struts 2, transversal beams 3, support beams 4 and shelves 5. The vertical struts 2 are connected to each other by means of the transversal beams 3, which transversal beams 3 are placed in parallel with each other. The support beams 4 are placed in parallel with each other between the transversal beams 3. The shelves 5 have the form of one or more nets, which nets are placed on the support beams 4. A storage rack has normally a number of pallet stations 1 placed side by side and placed above one and another, in which case the vertical struts 2 and transversal beams 3 each extend along a number of pallet stations 1.
On top of the shelves 5 support rails 6 are placed. In FIG. 1 one support rail 6 is shown upside down and one support rail 6 is shown mounted, for illustrative purpose. The support rails 6 are to receive feet of pallets, loading ledges or the like. The support rails 6 are placed at a distance from each other corresponding with the distance between the feet of pallets, loading ledges or the like. Each support rail 6 has a straight elongated main part 7. Two side parts 8 are placed at opposite sides of the main part 7, whereby each side part 8 is perpendicular to the main part 7 of the support rail 6. A horizontal flange 9 is placed perpendicular to each side part 8 at the side of the side part 8 distant from the main part 7. Thus, the horizontal flanges 9 are parallel with the main part 7. The horizontal flanges 9 are directed toward each other with an open space between them. There are rows of through openings 10 on each horizontal flange 9. In the shown embodiment one row of openings 10 is placed a short distance from one end of each horizontal flange 9 and one row of openings 10 is placed at a longer distance from the other end of said horizontal flange 13. In other embodiments there are openings 10 along the total length of each support rail 6. When mounted the support rails 6 are to be placed on top of the net forming the shelf 5, with the horizontal flanges 9 facing the shelf 5.
On the side of the main part 7 of the support rail 6 to be facing away from the shelf 5, there are one or more friction areas 11. In the embodiment of FIG. 2 there are three friction areas 11, formed of a number of through openings 12. The through openings 12 are punched or bored from below to give a raised surface around respective opening 12 on the upper side of the main part 7. A person skilled in the art realises that the friction areas 11 may be formed in different ways. Other examples include forming each friction area as an embossing in roll forming of the support rail 6 or adhering friction material 13 to the support rail by means of a suitable adhesive. The purpose of the friction areas 11 is to reduce the risk that goods placed on the support rails 6 will glide.
In the embodiment of FIG. 5 the through openings 12 are placed along the total length of the support rail 6 and not just in three areas. The support rail 6 of FIG. 6 has three areas of friction material 13 attached to the support rail 6. In FIG. 7 one area of friction material 13 is shown.
The support rails 6 are mounted to respective shelf by means of beam hooks 14 and/or net hooks 16. The beam hooks 14 are to be placed gripping around a transversal beam 3 and is therefore normally to be placed at the ends of the support rail 6 to be mounted. The net hooks 16 may be placed anywhere along the support rail 6 were there are openings 10 in the horizontal flanges 9 of the support rail 6. It is possible to use only beam hooks 14, only net hooks 16 or a combination of beam hooks 14 and net hooks 16 for the mounting of the support rails 6. The nets forming the shelf 5 may be mounted by means of special net fasteners 15 and/or by means of the beam hooks 14 used for mounting of the support rails 6.
Each beam hook 14 has two leg parts 17 and each leg part has a bent end 18 at the free end. The leg parts 17 are given a wave form, to have a kind of spring function. The angles and size of said wave form will influence the load that can be taken up by the beam hook 14. In FIG. 9 the beam hook 14 is shown not connected to a support rail 6 for illustrative purpose. The bent end 18 of each leg part 17 is to be placed in one opening 10 of the horizontal flange 9 of the support rail 6. The two leg parts 17 of the beam hook 14 are placed in corresponding openings 10 in the horizontal flanges 9 of a support rail 6 placed opposite each other. The beam hook 14 has further a hook part 19 at an end opposite the ends of the leg parts 17 to be received in the openings 10 of the horizontal flanges 9. The hook part 19 of respective beam hook 14 is to be placed around one of the transversal beams 3 and has a dimension adapted to the thickness of the transversal beam 3. The leg part 17 of the beam hook 14 is to be placed on the inside of the transversal beam 3, i.e. the same side as the net forming the shelf 5. In mounting of a support rail 6 by means of beam hooks 14, the bent ends 18 of the leg parts 17 of the beam hook 14 is first placed in openings 10 of the horizontal flange 9 of the support rail 6. The leg parts 17 are inserted from below, first through the net and then the bent ends 18 are inserted from below into the openings 10 of the horizontal flanges 9. The beam hook 14 is then turned to be placed around an adjacent transversal beam 3, whereby the bent ends 18 of the leg parts 17 will be placed abutting the horizontal flanges 9 of the support rail 6. The leg parts 17 of the beam hook 14 are bent in such a way that they will follow the profile of the transversal beam 3. The support rail 6 will be held in place by means of the bent ends 18 of the leg parts 17 abutting the horizontal flanges 9 and the hook part 19 received around the transversal beam 3. The beam hooks 14 will also hold the shelf 5 in place. To facilitate loosening of a beam hook 14, the hook part 19 may have a raised portion (not shown) for receiving a tool, by which tool the hook part 19 is bent away from the transversal beam 3.
Each net fastener 15 has a central part 20 and two legs 21 at opposite ends of the central part 20. Between the central part 20 and respective leg 21, a hook part 22 is formed, which hook part 22 is to be received at the bottom of one of the transversal beams 3. At the free ends of respective leg 21 a hook 23 is formed, which hook 23 is to grip the net. The legs 21 are to be placed on the inside of the transversal beam 3, i.e. the same side as the net. In use the legs 21 of the net fastener 15 is inserted from below through openings in the net, in such a way that the hooks 23 of the legs 21 will grip the net. Thereafter the hook part 22 is placed around the transversal beam 3.
The net hooks 16 are used for mounting of the support rail 6 to the nets forming the shelf 5. Each net hook 16 has a central part 24, which central part 24 goes over into a vertical part 26 at each end of the central part 24. The vertical parts 26 are perpendicular to the central part 24, and are parallel extending in the same direction. Each vertical part 26 goes over into a horizontal part 27, which horizontal parts 27 normally are in parallel with the central part 24. After each horizontal part 27 a leg part 25 is formed. Each leg part is bent to form an apex 28, which apex 28 is to be inserted through an opening in the net forming the shelf 5. The parts forming the apex 28 diverge from each other to a maximal distance, which maximal distance exceeds the dimension of an opening in the net. In use free ends of the leg parts 25 are received in one opening 10 of one respective horizontal flange 9 of the support rail 6. When attaching a net hook 16 to a support rail 6, the support rail 6 is first turned with the side to be facing the shelf 5 facing upwards. The leg parts 25 of the net hook 16 are then inserted in one opening 10 of a horizontal flange 9 each. The central part 24 is received under respective horizontal flange 9, spanning the distance between the horizontal flanges 9. The parts forming the apex 28 of each net hook 16 are flexible enough to be pressed through the openings of the net. In mounting of the support rail 6 by means of the net hooks 16, the net hooks 16 are first mounted to the support rail 6. Then the support rail 6 is placed on top of the shelf 5, whereby the leg parts 25 of the net hooks 16 are pressed down through openings of the net forming the shelf 5. The leg parts 25 will expand again after passing of the net, whereby the support rail 6 is held at the net. By amending the angles by which the leg parts of the net hook 16 are bent, the force that can be taken up by said net hook 16 will vary.
The beam hooks 14, the net fasteners 15 and the net hooks 16 are normally made of one single metal thread each. The dimensions of the beam hooks 14, net fasteners 15 and net hooks 16 are adapted to the dimensions of the parts they are to be attached to. The actual sizes of beams and nets often vary between different storage racks. The dimension of the beams may vary both in height and in depth.
A special tool (not shown) may be used when mounting the net hook 16 in the openings 10 of the support rail 6. The special tool has one part with a longitudinal slit to grip one of the leg parts 25 of the net hook 16. A handle is attached to the gripping part of the tool. In use a first end of the net hook 16 is first placed in an opening 10 of one flange 9 of the support rail 6. The gripping part of the tool is then placed on the leg part 25 of the net hook 16 relatively close to a second end of the net hook 16. There after the net hook 16 is swung under the opposite flange 9 by means of the tool. Finally the second end of the net hook 16 is placed in an opening 10 of said opposite flange 9.
Due to the relatively large distance it may be difficult to press down the net hook 16 only by manual force. A tool 29, shown in FIG. 13, may be used in mounting of the support rail 6 by means of a net hook 16 to the net. The tool 29 may be made by one thread. The tool has a handle 30 at one end, which handle 30 is transformed into two legs 31 at an opposite end. At the free end of each leg 31 a hook 32 is formed, which hook 32 is perpendicular to the leg 31. The hooks 32 at the free ends of the legs 31 are to grip around threads of the net. In use the support rail 6 is placed on the net with at least one net hook 16 attached to the support rail 6. The apexes 28 of the at least one net hook 16 is placed in openings of the net, with the parts forming each apex 28 resting on the net. The tool 29 is placed above the support rail 6, close to the position of the at least one net hook 16, with the hooks 32 of the legs 31 gripping the net. Then the net hooks 16 are pressed down into the net, by turning the tool 29 around the hooks 32 gripping the net, whereby the tool 29 will press on the upper side of the support rail 6. Often there is only access to the storage rack 1 from one side, in which case there may be a relatively large distance from the side of a shelf 5 to a net hook 16 to be pressed down into the net. The tool 26 for mounting the support rails 6 by means of the net hooks 16 may be combined with the special tool described above, for mounting the net hooks 16 in the openings 10 of the support rail 6.
As indicated above a support rail 6 may be mounted by means of only beam hooks 14, only net hooks 16 or a combination of beam hooks 14 and net hooks 16. The beam hooks 14 can take up larger forces than the net hooks 16. Therefore, the choice of which types of hooks to use can depend on the forces that may be charged onto the support rail 6.
For safety reasons the beam hooks 14 and/or net hooks 16 holding the support rails 6 should come loose if the support rail 6 is exposed to a certain minimal force. For the beam hooks 14, one way of guaranteeing the safety demands is to dent the thread of the leg parts 17 adjacent to the hook part 19 to be placed around a transversal beam 3. If the support rails 6 are exposed to excessive forces, the beam hooks 14 will break at the dents. For the net hooks 16, one way of guaranteeing the safety demands is to adapt the size and bending of the leg parts 25 to the sizes of the openings of the net, receiving the net hooks 16.
