[0001] The invention relates to an element for stacking frames formed by profiles mainly
shaped in the form of an L.
[0002] The invention has for its object to provide a cheap element that can be arranged
in the corners of the frames so that the frames can be easily stacked without the
risk of shifting or damage. The frames may be or not be provided with a panel clamped
therein.
[0003] The element according to the invention is distinguished by a plate-shaped web provided
with two flanges normal thereto and lying one on each side of said web, the flanges
being at an angle to one another corresponding with the angle of the frame and provided
with at least one rib parallel to and at a distance from a flange, said distance corresponding
to the thickness of-a limb of the L-shaped profile.
[0004] Such an element is comparatively small and can be readily slipped onto one limb of
the L-shaped profile near the corner of the frame. On both sides of the corner the
outer rim of the frame is protected by the flanges, whilst the stacked frames do not
touch one another owing to the plate-shaped web arranged between them. In this manner
the frames are protected to the optimum with the aid of only one element arranged
on one corner of a frame.
[0005] In order to permit of stacking frames of different sizes it is preferred to dispose
the standing rim of a flange at that distance from the prolongation of the other flange
which corresponds to at least the width of the other limb of the L-shaped profile.
It is thus ensured that the web is in direct contact with a continuous frame rim of
the neighbouring frame.
[0006] In order to establish a sufficient firm connection it is preferred to provide a second
rib similar to the first rib opposite the other flange.
[0007] In order to establish a clamping connection between the element and the frame in
accordance with the invention the free rim of each rib extending parallel to the web
is inclined towards the flange.
[0008] The invention will be described more fully with reference to an embodiment.
[0009] The drawings shows in:
Fig. 1 a perspective view of an element embodying the invention,
Fig. 2 a perspective view of the inner corner of stacked frames,
Fig. 3 a complete stack of frames provided with stacking elements,
Fig. 4 a stack formed by frames of unequal sizes.
[0010] Reference numeral 1 designates the plate-shaped web of the stacking element provided
with two flanges 2 and 3. The flanges are normal to the web plate 1 and .are at an
angle α by their prolongations. This angle α corresponds with the angle of the frames,
usually an angle of 90°. The flanges extend one on each side of the plate-shaped web
1, whilst the upper part of fig. 1 is larger than the lower part of the flanges.
[0011] At an distance a from each flange 2, 3 is provided a rib 4, 5. These ribs extend
parallel to the associated flange. The free rim 6 extending parallel to the web 1
is slightly inclined towards the associated flange so that a smaller distance b from
the flange is obtained.
[0012] The frames to be stacked are each mainly formed by L-shaped frame profiles 7, one
limb 7' forming the outer rim of the frame and the other limb 7" forming the front
face of the frame. The thickness of the limb 7' is designated by c, it being noted
for completeness' sake that the limb 7' has two open channels 8 and 9 for fastening
the profiles to one another to fasten panels P in the frame by means of fastening
means not lying within the scope of this invention. The panels P may be formed in
order of succession by a glass plate, a picture and a back plate.
[0013] The width of the limb 7' is designated by d.
[0014] Each stacking element can be simply arranged in place by pressing the plate-shaped
web 1 against the underside of the frame, the ribs 4, 5 getting on the inner side
of the corner of the frame and the flanges 2, 3 on the outer side thereof. The distance
a corresponds to the thickness c of the limb 7'. Since the distance b is smaller than
a, the element will automatically clamp tight in the corner.
[0015] The frames can be stacked as shown in figs. 2 and 3, in which case the outer flanges
2, 3 grip around the outer side of each frame by the downwardly extending part. In
this way a shift of frames of the same size is prevented in all directions. The frames
may be bound together, for example, by means of stretching strips 10.
[0016] From fig. 3 it.is apparent that the frames are lying at a distance from one another,
said distance being equal to the thickness of the plate-shaped web 1. The outer side
of the stack of frames is protected near the corners by the superjacent flanges 2,
3.
[0017] Fig. 4 illustrates a possibility of stacking frames of unequal sizes. For this purpose
it is necessary for the standing rims of ons flange 11 to be at a distance e from
the prolongation of the other flange. This disiance e corresponds to the width d of
the limb 7' of each frame profile. Thanks to this precaution the stacked frame profiles
are prevented from relatively shifting in place even if the frame does not have the
same dimensions.
[0018] The invention is not limited to the embodiment described above; is is noted , for
example, that one rib 4 or one rib 5 may be sufficient. The centering effect is maintained
by the flanges 2 and 3, whilst one rib is sufficient to hold to elements in the corners.
