SG184135A1 - Support frame for racks - Google Patents

Abstract

A support frame to be laid on a pair of cross-members (16) of a rack has at least two U-section rails (12) and a plurality of C-section rails (11) running transversely thereto, of which the flanges (14) are joined to the central webs of the U-section rails (12). The distance between the U-section rails (12) of the support frame is dimensioned such that said rails fit exactly between the two cross-members (16) of the storage rack. The central webs of the C-section rails (11) are perforated, wherein at least some of the holes (17) have rims (18) projecting from the surface of the C-section rails (11), which faces away from the U-section rails (12).

SUPPORT FRAME FOR RACKS

Description

Prior art

For supporting pallets in storage shelves, it is common to use bars extend- ing 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 verti- cally and with sufficient accuracy there is a danger for the bars to slip and fail to support the pallets properly.

DE 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 mem- bers.

Summary of the invention

The above problem is met by the support frame defined in claim 1. 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 the embodiment of claim 2, the support frame may be assembled at the site, thereby reducing transportation expenditure. The feature of claim 3 prevents the frame from being distorted in a parallelogram manner.

The feature of claim 4 not only results in a saving of material and weight but also forms a safety measure. In the embodiment of claim 5, slippage of the stored goods is counteracted.

The feature of claim 6 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 claim 7 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 as defined in claim 8, ensures a stable posi- tioning of the support frame which does not slip in the depth direction of the shelf.

Brief description of the drawings

An embodiment of the invention will be explained in detail below with refer- ence to the drawings in which:

Fig. 2 a side view of the support frame taken from below in Fig. 1;

Fig. 3 a side view taken from the left in Fig. 1;

Detailed description of an embodiment

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 (Fig. 4) of the C-profile bars 11 are connected by means of screw bolts and nuts to the centre webs 15 of the U-profile bars 12 which face upward in Fig. 2.

In the side view of Fig. 3, two cross-members 16 of a storage shelf are shown in cross-section. The mutual spacing of the U-profile bars 12 of the support frame is so dimensioned that they come to lie inside the shelf cross-members 16 so closely that they substantially prevent the support frame from moving in the depth direction of the shelf. At the same time, they ensure that the support frame can be placed onto cross-members 16 only in such a manner that the C-profile bars 11, which serve to receive goods to be stored, specifically pallets, extend in the depth direction of the shelf and the overall frame is held in its plane with the proper angular orientation. In addition, the U-profile bars 12 determine the amount by which the C-profile bars 11 extend beyond the cross-members 16 in the depth direction of the shelf, thereby ensuring that the C-profile bars 11 lie within the space available for the overall shelf.

In the embodiment shown in Figs. 1 and 2, two C-profile bars 11 are dis- posed closely together near either end of the U-profile bars 12 whereas there is a greater spacing between the C-profile bars 11 in the central area of the support frame. Both lateral portions of the support frame are thereby given high stability so that, in case a pallet is lowered in a tilted manner, sufficient load-bearing capacity is available on the respective side of the support frame.

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 sup- port frame but also provide fire a protection by passing sprinkler water.

As shown in Figs. 4 and 5, a part of the holes 17 are embossed upward to form rims 18 protruding form the surface of the C-profile bars 11 facing away from the U-profile bars 12, which rims prevent or at least impede slippage of the goods stored on the support frame.
