Description

The invention relates to an adjustment gate arrangement for corner supports made up of four angular profiles, a head and a door bend, At the lower end of the ifick supports a pallet of the specified size as a pallet-up holding the btapel-bottom setting frames.

Composable pallet collars are used, for example, in the deep-freeze industry as a stacking aid for storing frozen food on pallets in cold stores, in order to be able to stack four to five such pallets on top of one another and thus use the barely available height in the cold stores. Compared to the use permanently mounted stacking shelves these assembled from four corner posts, a top and • INEM foot frame pallet collars significant advantages are so far as the pallets part is using the collars in cold stores, depending on the camp perimeter constructed stacking racks and on Storage goods stored on the pallets can remain on the pallet when they are removed from the assembly of the stacking frame for transport to a customer. The corner supports, head and floor frames can - as long as they are not used in the stacking frame - be stored in a space-saving manner. Unlike fixed shelves, these pallet collars do not have any diagonal struts which they reinforce against lateral, ie horizontal forces. Rather, the rigidity in this direction is determined solely by the stored goods stacked on the pallets

Due to the stiffener used On the one hand, it is therefore the stability the collars increased against horizontal forces and on the other hand, a lateral closure is created to prevent stored goods from falling, for example

A further increase in stability can thereby be achieved that the front side stiffening grille and / or the transverse side stiffening grille by about placed diagonally on the grid and on at least one Part of your crossing points welded to the horizontal and vertical round steel or wire sections Diagonal bars or wires are stiffened against deformation in the lattice plane.

On the inside of the profile legs of the corner supports adjacent front side reinforcement grids are attached to the associated profile legs of the corner supports held pressed, while the transverse side reinforcement grid are secured against tipping inwards by the stored goods stacked on the pallets. In case that the cross-side reinforcement grille also then against a such tilting should be secured if the pallet is not loaded in individual cases is recommended it is, at the opposite end regions of the upper horizontal termination of the transverse side reinforcement grid forming flat profiles each have a locking device for the form-fitting connection of the cross-side stiffening grid to be provided with the assigned corner supports.

In. a preferred development of the invention these locking devices each have a swivel bolt articulated in the end regions of the flat profiles on, between a parallel to the flat profile and the associated back support on the Outside overlapping locking position and a pivoted up release position pivotable is.

In order to protect the reinforcement grids against corrosion, it is best to include them including where appropriate to galvanize provided swivel bolts.

In Fig. 1 is a frame arrangement with two flat pallets 10 shown, in which the pallets are arranged in a vertical distance one above the other in alignment Form storage floors to accommodate the goods to be stored. You pallets IQ are used with so-called collars 12 supported, whereby by placing additional pallets by means of appropriate collars on the in the Drawing above the collars an increase in the frame and thus an increase in the storage capacity is possible with the same footprint. In practice - depending on the amount of available standing storage room - up to five pallets 10 with collars 12 can be stacked on top of each other.

The Aufsetzrahmen 12 are not a rigid structural component, but are made of four at the corners of a pallet depositable, made of angular profiles , a foot frame 16 made of flat iron and also made of flat iron that surrounds the corner supports in the lower area of the pallet produced and assembled in the corners by square corner plates 18 connected head frame 20 easy and quick to assemble and dismantle. In the case shown, the collars 12, which are known per se, are designed in accordance with the technical delivery conditions for flat pallets and pallet accessories of the Deutsche Tief-Kühlinstituts eV and therefore do not need to be described in more detail.

If the pallets 10 are loaded by tightly packed storage goods, the collars are also multiple stacking sufficiently stable to also

In this form illustrated in FIG. 1 on the lower collet frame 12 and in FIGS. 5 and 6, the transverse side reinforcement grids 24 are already fully functional. The insertion of the transverse side reinforcement grids is carried out in the manner indicated in Figure 1 with respect to the front reinforcement grid 24 of the lower mounting frame 12 so that the one - right in the drawing - vertical edge of the reinforcement grid is inserted into the KckstUtze l4 that there Recess 42 in the flat iron 36 engages around the associated horizontal Hundstahlabschnitt of the adjacent Stirnsei th stiffening grid 22. Then the other - in the drawing, the left vertical edge of the stiffening grid 24 is pivoted in the direction of the arrow a to the second corner support, and then finally the recess 42 located at this end of the flat iron 36, the corresponding round steel section 26 of the second front side reinforcing grid 22 encompasses. After the space of the pallet enclosed by the stiffening grids 22, 24 has been filled with stored goods, the transverse side stiffening grids 24 can no longer be pivoted back, that is, the mutually supporting stiffening grids in the attachment frame 12 are fixed and effect the desired transverse stiffening without having to do this with the attachment frame would have to be screwed or otherwise laboriously connected.
