[0001] The invention relates to a shell bracket comprising two mutually square legs provided
with openings for applying mounting screws therethrough, said shell bracket being
formed of a strip of sheet metal, shaped in such a way that the legs merge into each
other with a curved part.
[0002] Such shelf brackets are used at a large scale but have the disadvantage that the
appearance thereof does not meet high demands. In the first place the legs and in
particular the joining corner will have to be stiffened, unless the sheet strip is
made of a thick material. This is not possible, however, for economic reasons. On
the other hand the heads of the mounting screws always remain in sight.
[0003] In connection therewith such shelf brackets will not be applied at those locations
where specific esthetic demands will have to be met.
[0004] The invention has as an object to remove this disadvantage in a simple and economic
manner and provides to that end that an L-shaped protecting cover is positioned over
the legs, said cover in particular being made of plastic and being substantially U-shaped
in cross-section, the mutually opposing inner sides of said cover being provided with
projections there where these inner sides are present at the corner outside the curved
part of the sheet strip when the cover is mounted on the shelf bracket, said projections
snapping over the curved part of the sheet strip while the legs of the cover are resiliently
deflecting when mounting the cover, to keep the cover in its place afterwards.
[0005] Accordingly mounting of such a cover does not require special tools and may take
place in a particularly short time without any technical understanding being required.
[0006] Preferably the sides of the projections facing the shelf bracket after said cover
is mounted on the shelf bracket, will be substantially in line with each other. This
means that they keep the cover firmly in its place on the shelf bracket. Nonetheless
removal of the cover is possible in a fairly simple manner by pulling away the end
of one of the legs of the cover from the shelf bracket. A deformation of the cover
will then take place and especially of that part where the legs of the cover join
each other, in such a way that the projections positioned at the inner sides of the
cover will move away from each other. In that way the cover is released from the shelf
bracket.
[0007] According to a further elaboration of the invention it is provided, that in the interior
of the cover supports are provided, which cooperate with parts of the shelf bracket
to keep the cover in its proper position with respect to the shelf bracket.
[0008] In that way it is not only achieved that the cover is clamped onto the shelf bracket
in the proper position after mounting of the shelf bracket, but the cover may also
be mounted in the proper position on the bracket prior to mounting the shelf bracket
so that the assembly may be shipped as a unit and be marketed as such.
[0009] In that case the supports in particular will be formed by two spaced apart strips,
standing at right angles to the support plane of the cover and cooperating with a
projecting part of the sheet strip, of which the shelf bracket is made.
[0010] The invention will now be further elucidated with reference to an embodiment, shown
in the drawings, in which:
Fig. 1 shows a cross-section of an assembly of a shelf bracket and a cover according
to the invention over the central longitudinal plane of the legs to wit along the
line I-I of Fig. 2;
Fig. 2 shows a rear view of the assembly of Fig. 1;
Fig. 3, 4 and 5t show cross-sections along the lines III-III, IV-IV and V-V respectively
of Fig. 1; and
Fig. 6 shows a cross-section along the lines VI-VI in Fig. 1 and Fig. 4.
[0011] The assembly shown in the drawing consists of the shelf bracket 1 and the cover 2.
The shelf bracket 1 comprises the legs 3 and 4 which are obtained by bending a strip
of sheet metal 5, provided with the projecting part 6 to provide the legs 3 and 4
with adequate stiffness. The strip of sheet metal 5 comprises the curved part 7 forming
the transition between the legs 3 and 4.
[0012] In the legs 3 and 4 the openings 8 are present for passing screws - not shown - therethrough
with which the shelf bracket is mounted.
[0013] After mounting the L-shaped cover 2 is positioned onto the shelf bracket the legs
9 and 10 of it being slightly longer than the legs 3 and 4 respectively of the shelf
bracket 1.
[0014] As especially appears from Figs. 1 and 5, the cover 2 is semi-circular in cross-section
and the ends of the legs 11 are present in the support plane 12. As especially appears
from Fig. 1 the support plane 12 will come to rest against the surfaces against which
the shelf bracket 1 is resting as well. At the location where the legs 9 and 10 are
joining each other they thus have a corner part 13, located outside the curved part
7 of the sheet strip 5.
[0015] As particularly appears from Fig. 3 projections 15 are provided on the inner sides
14 of the legs 11, which will snap over the curved part 7 when mounting the cover
2 onto the shelf bracket 1 and will be held on the shelf bracket by means of the sides
16.
[0016] When, however, the cover 2 has to be removed from the shelf bracket 1 either the
end of one of the legs 9 or 10 or the ends of both legs can be grasped and be pulled
in the direction of the other leg. By this a deformation of the cover will occur to
such an extent, that the legs 11 will be moved apart in the direction of the arrows
P in Fig. 3. The cover 2 may then be removed easily from the shelf bracket 1.
[0017] The supports 17 are taking care for a proper centering of the cover 2 onto the shelf
bracket 1, said supports in particular being shown in Figs. 4 and 6. The supports
17 comprise in particular two spaced apart strips 18 which, with a view to their strength,
may be interconnected over a specific part of their length, as this in particular
appears from Fig. 4. The strips 18 are joining the projecting part 6 of the sheet
strip 5, so that in the mounted condition of the cover 2 the latter will always occupy
the proper position with respect to the shelf bracket 1.
[0018] For further centering and stiffening of the cover 2 supports 19 may still be provided,
as this appears especially from Figs. 5 and 6. The strips 19 may extend to the wall
20, which closes the end of the leg 9 or 10 outwardly.
[0019] It will be obvious that the cross-section of the cover 2 may have another shape as
well, such as for example a more rectangular, elliptical shape or the like. Many other
modifications can be made as well without departing from the inventive concept.
