SUPPORT FRAME FOR RACKS
A support frame to be laid on a pair of cross-members of a shelf having at least two U-profile bars and C-profile bars extending transverse thereto and having flanges connected to the center webs of the U-profile bars. The space between the U-profile bars of the support frame is so dimensioned that the U-profile bars of the support frame just fit between the two cross-members of the storage shelf. The center webs of the C-profile bars are perforated, wherein at least some of the holes have rims protruding from the surface of the C-profile bars facing away from the U-profile bars.

PRIORITY CLAIM
This patent application is a U.S. National Phase of International Patent Application No. PCT/EP2011/001742, filed 7 Apr. 2011, which claims priority to German Patent Application No. 20 2010 004 600.9, filed 7 Apr. 2010, the disclosures of which are incorporated herein by reference in their entirety.
FIELDFor supporting pallets in storage shelves, it is common to use bars extending in the depth direction of the shelf, which bars are individually placed on pairs of cross-members of the shelf. If the pallets are not lowered onto the bars not vertically and with sufficient accuracy there is a danger for the bars to slip and fail to support the pallets properly.
BACKGROUNDDE 43 01 475 A1 discloses a support structure for a storage shelf in which a specifically constructed profile beam is fixedly connected to the shelf cross-members to support pallets.
WO 2009/114256 A1 discloses a pallet constructed of metal profile members.
SUMMARYThe above problem is met by the support frame disclosed herein. The fixed connection of C-profile bars, which serve to support goods to be stored, to U-profile bars extending perpendicularly thereto creates a unit which can be simply laid on the shelf cross-members and, if the spacing between the U-profile bars is properly selected, results in an arrangement of the C-profile bars which practically cannot move in the depth direction of the shelf.
In at least one disclosed embodiment, the support frame may be assembled at the site, thereby reducing transportation expenditure. As an additional feature, the frame may be prevented from being distorted in a parallelogram manner by using flanges of the C-profile bars that are screwed to the center webs of the U-profile bars.
Perforation of the C-profile bars not only results in a saving of material and weight but also forms a safety measure. In the disclosed embodiment wherein at least some of the holes have rims protruding from the surface of the C-profile bars facing away from the U-profile bars, slippage of the stored goods is counteracted.
The feature wherein the length of the C-profile bars is greater than the space between the U-profile bars achieves a spatial fixation of the support frame, wherein the C-profile bars supporting the stored goods do not extend beyond the given depth of the shelf.
The feature of wherein the space between two C-profile bars is smaller near either end of the U-profile bars than in the central area of the support frame is of advantage with respect to the stability of the support frame in case a pallet is lowered in a tilted manner.
The combination with a shelf ensures a stable positioning of the support frame which does not slip in the depth direction of the shelf.
At least one disclosed embodiment will be explained in detail below with reference to the drawings in which:
The support frame shown in the drawings consists of a plurality, five in the example shown, of C-profile bars 11 extending parallel to one another, and two U-profile bars 12 extending perpendicularly thereto. At the locations designated by 13, the mutually facing flanges 14 (

In the disclosed embodiment shown in
The centre webs of the C-profile bars 11 are provided with a plurality of holes 17. The holes 17 not only reduce the material usage and weight of the support frame but also provide fire a protection by passing sprinkler water.
