La distance entre les rails en U (12) du cadre d'appui est calculée de manière à ce qu'ils passent juste entre les deux traverses (16) de l'étagère. Les barres centrales des rails en C (11) sont perforées, au moins certains des orifices (17) comprenant des bords d'orifice (18) saillants sur la surface des rails en C (11) opposée aux rails en U (12).

Abrégé anglais

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).

C-profile bars is smaller near either end of the U-profile bars than in the
central area
of the support frame.

SHELF SUPPORT FRAME
Field and Background
For 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.
DE 43 01 475 Al 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 Al discloses a pallet constructed of metal profile members.
Summary
Certain exemplary embodiments can provide a combination of a storage
shelf having vertical columns and cross-members connecting them, and a support
frame comprising at least two U-profile bars and a plurality of C-profile bars
extending transversely thereto and having flanges connected to the centre webs
of
the U-profile bars, wherein the space between the U-profile bars of the
support
frame is so dimensioned that they just fit between both cross-members of the
storage shelf.
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 another embodiment, the support frame may be assembled at the site,
thereby reducing transportation expenditure. Another feature prevents the
frame
from being distorted in a parallelogram manner.

Another feature not only results in a saving of material and weight but also
forms a safety measure. In another embodiment, slippage of the stored goods is
counteracted.
Another feature 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.
Another feature has an 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 according to another feature ensures a stable
positioning 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
reference to the drawings in which:
Fig. 1 a plan view of a support frame;
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;
Fig. 4 an enlarged end view of a C-profile bar; and
Fig. 5 an enlarged cross-section of a part of the perforated C-profile bar.
Detailed description
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
disposed 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 support
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.
