Description

l5 20 25 30 35 8205090-7 2 loaded pallet. In particular, the invention aims to provide a fastening mechanism for releasably attaching a pallet frame to a conventional pallet, comprising the pallet's laterally limiting deck edge boards and the pallet's legs forming edge footboards placed vertically at a distance from each other. The invention further has for its object to provide a fastening mechanism which meets the above requirements and is suitable for releasably connecting a pallet frame to a pallet, allowing the pallets to be stacked on top of each other.

The characteristic features of the invention appear from the following claims.

The invention is based on a special, hook-like hook element belonging to the frame element of the pallet frame and on a locking plate arranged at a height at a distance from it, which hook element tends to slide from the side behind a support element belonging to the pallet, e.g. a footboard, with the frame element fitting degree inclined outwards, after which the frame element can be swung up in a vertical position, whereby the locking plate locks the element in height against a support shoulder, eg the edge board of the tire. The frame elements can then be joined at the elements' frame constructions, for example posts, above the pallet either laterally around the pallet or suitably across the pallet, for example in a manner known from previous pallet frames. The fastening mechanism according to the invention for a pallet frame enables the pallet frame to be fastened around a pallet loaded with goods without the need to remove goods from the pallet, as well as disassembly of the pallet frame from such a loaded pallet. The mechanism is extremely simple in its construction and thus more advantageous than before in terms of manufacturing costs.

The fastening mechanism enables easy and fast detachable fastening of the pallet frames of pallets so that stacking on each other is allowed and a stable construction of pallets is obtained.

The invention is described in detail in the following with the aid of exemplary embodiments with reference to the accompanying drawing, in which Fig. 1 shows, seen from one end of the pallet, a pallet frame equipped with a fastening mechanism according to the invention, connected to a pallet, Fig. 2 shows in perspective view the parts connecting to the fastening mechanism for pallet frame according to Fig. 1, Fig. 3 shows, seen from the side, the frame fastening mechanism according to another embodiment of the invention, and Fig. 4 shows in side view the fastening mechanism according to a third embodiment of the invention.

Fig. 1 shows the pallet frame 1 releasably attached to the pallet 2, the frame consisting of two frame elements 3 connected on the opposite sides of the pallet and releasably connected to each other by bolt joints 18.

According to the invention, both frame elements 3 have laterally projecting, hook-like hook element 4 and the ledge-like locking plate 5, vertically at a distance from each other.

Furthermore, the pallet 2 has similar shoulder-like support element 6 cooperating with hook elements and the support shoulder 7 cooperating with the locking plate. The mentioned parts have been arranged so that the frame element 3 can be phased to the pallet by sliding bent down the hook element 4 over the support element 6, i.e. the edge board 12 of the pallet, in behind it for locking and that it is pushed at said vertical post at a distance from the hook element above this fastened and also the side projecting lock plate 5 under the support shoulder 7, i.e. the edge board 9 of the pallet tires. The said locking is advantageously performed with the frame element 3, i.e. the vertical post 13 inclined outwards, by first locking the hook element 4 behind the support element 6 and then raising the frame element, the locking plate being locked under the support shoulder 7. Next, the two sides of the pallet 2 are connected. according to the above description, the frame elements 3 are detachably connected to each other on the upper side of the pallet, for example the vertical posts 13 of the frame elements are fastened to each other by connecting the horizontal supports fixedly attached to the top ends of the posts with each other, for example in a previously known manner by means of bolt, sprint or similar Fastening 18.

Fig. 2 shows the fastening elements for the lower end of the vertical support 13 of the frame element 3 according to Fig. 1, i.e. the hook element 4 and the locking plate 5. The hook element 4 consists of a plate in cross section, welded vertically to the frame element 3, which has a flange-like shape of an upside-down U-profile to its cross-section. The hook element 4 is attached to the vertical post 13 with one side leg of the U-profile, while the middle part 15 of the profile together with the other legs 16 of the profile forms a downwardly facing hook element 4 projecting from the post. The locking plate 5 consists of a flat flange element which has been welded at the post 13 above the hook element 4 at a distance therefrom. The hook element 4 and the locking plate 5 are both placed in line in the vertical direction, at a certain distance from one edge of the vertical post 13 to enable the post to be locked in line with the foot of the pallet, with the hook element and the locking plate next to the foot.

In the embodiment according to Figs. 1-2, the frame element 3, i.e. the vertical post 13, is fixed to the pallet in such a way that the hook element 4 hooks into the lower end of the post over the edge footboard 12 of the pallet 2 and behind it, thereby preventing displacement of the post downwards and towards side, out from the podium. Furthermore, the reading claw 5 goes under the edge board 9 of the deck 8, thereby preventing upward movement of the post 13. The post 13 supports against the outer edges of said edge footboard 12 and of the edge board 9 of the deck 8 and prevents the post from sliding in the direction of the pallet 2.

In the embodiments shown in Figs. 1-3, the hook element 4 has been placed above the support element 2, while the locking plate 10 is placed on the opposite side of the support shoulder 7 to provide complete vertical support to the frame element. Furthermore, in order to improve the height support, Fig. 3, the locking plate 5 has been connected to the hook element 4 with an intermediate strip for their support against each other. The extent of the reading plate 5 perpendicular to the frame element 3 is smaller than the corresponding dimension of the hook element 4, which enables the hook element to be locked first behind the support element 6 with inclined post 13 and then erection of the post with the locking plate against the shoulder 7. The hook element has been placed at the bottom and the locking plate 5 above the hook element.

In the embodiment shown in Fig. 4, the edge constructions of the pallet consist of two parallel, superimposed pipes, of which the upper constitutes the support element and the lower support shoulder. The hook element 4 has been placed above the reading plate 5. The frame element is fixed in this case by tilting the vertical post 13 over the pallet (indicated by dashed lines 14) and sliding the hook element 4 under the support element 6. Then the post 13 is raised, whereby the loading plate 5 penetrates in over the support shoulder 7 while supporting the same, while the post is pressed against the support elements and the support shoulder constituting the frame tubes, ie against the elements corresponding to the edge board of the tire and the edge footboard.

The invention is not limited to the embodiments set forth above and its applications may vary within the scope of the appended claims. It is then conceivable for such an application of the invention that the hook element 4 and the locking plate 5 are not placed as Figs. 1-4 show between the support element 6 and the support shoulder 7, but for example so that the hook element 4 is placed below the support element 6 and locking claw 5 is located at the top above the support shoulder 7; alternatively, the hook element can abut against the support element 6 located below it on its upper side and the locking plate 5 located below the hook element can support against the support shoulder on its underside.
