Description
BACKGROUND OF THE INVENTION
This invention relates to a suspension device which may be used by
arranging pictures, such as reproductions or posters on a wall.
For arrangement of reproductions, posters, or the like printings on
a wall it is known to place a single clamp rod at the top and at
the bottom of the poster so that the poster looks more attractive.
A string is fixed in the upper rod so that the poster may be fixed
to a nail in a wall. The clamp rods may only be used for posters or
reproductions having a certain width; therefore their application
possibilities are limited.
The object of the present invention is to provide a suspension
device of the above mentioned kind, and which may be used for
posters, reproductions, or the like printings of different
widths.
SUMMARY OF INVENTION
The suspension device according to the invention is characterized
in that it comprises at least one pair of parallel frame portions,
each portion consisting of two clamp rods which are arranged in a
covering rod so that they may be displaced as a telescope in the
longitudinal direction of the covering rod. Hereby is obtained that
the clamp rods may be drawn from each other or moved towards each
other depending on the width of the poster or reproduction to be
suspended. The suspension device looks as it is specially
manufactured for the present poster or reproduction.
According to the invention the upper side of the clamp rods may be
provided with at least one longitudinal groove, wherein at least
two suspension portions having holes may be displaced. Hereby it is
possible to move the suspension portions into such positions which
correspond with such nails which have previously been driven into
the wall.
Further according to the invention the clamp rods may have a
profile which is substantially H-shaped, the lower ends of the side
webs of said H being provided with inwardly and upwardly extending
protrusions, while the upper end of the side webs of said H has an
inwardly extending protrusion defining part of said groove. Hereby
is obtained that a poster or reproduction may easily be clamped
between the side webs, as it is pressed between the lower end webs.
Further is obtained that the groove will show a certain
undercutting.
According to the invention the horizontal transverse web of the
H-profile may be formed as two relatively thin webs which are
arranged in parallel and spaced. Hereby the rigidity of the clamp
rod is improved.
Further according to the invention it is possible that the
H-profile has a relatively great horizontal thickness, and that the
uppermost web of the relatively thin horizontal webs in the middle
of said H is provided with a bulging part for forming two grooves
at the upper end of said H. Hereby is obtained that the suspension
device is particularly suitable for very heavy reproductions, and
such reproductions which are covered by a clear sheet. Independent
of which side of the clamp rod is facing the wall, there will
always be one groove which is close to the wall. Hereby the
arrangement of the suspension portions is made very easy.
According to the invention it is also possible that the cover rod
may have a profile which circumscribes the profile of the clamp
rods, the webs of the cover rod profile being relatively thin
compared with the thickness of the side webs of said clamp rods.
Hereby is obtained that the clamp rods are guided very safely
within the cover rod.
According to the invention each suspension portion may have such
thickness that the rear side thereof extends behind the edge of
said clamp rod or registers with said edge. Hereby is obtained that
the suspension portion may be arranged very close to the wall at
the place where the suspension device should be arranged. This
ensures safe fixing of the suspension device.
According to the invention the side webs of said H may be
relatively thick, whilst the transverse web or webs in the middle
of said H are relatively thin. Hereby is obtained that the end webs
extending from the side webs may keep a poster or reproduction with
a certain elasticity.
Finally according to the invention two frame portions may be
connected with two clamp rods, the length of which is constant.
Hereby is obtained that the poster or reproduction to be suspended
may be provided with a frame all the way round along its edges.

DETAILED DESCRIPTION
The suspension device as shown in FIG. 1 consists of two frame
portions 1 and 2, substantially corresponding with each other in
construction. The frame portion 1 consists of two elongated members
or clamp rods 3 and 4 which - in telescopic manner - may be moved
within a sleeve member or cover rod 5. From FIG. 2 it appears how
the profile of the cover rod nearly surrounds the profile of a
clmap rod completely.
On the upper side of the clamp rods a longitudinal groove 6 is
provided. In this groove suspension portions 7 are arranged. These
portions may be moved so as to register with two nails which have
previously been driven into the wall on which the suspension device
is to be arranged.
As appears from FIG. 1 the clamp rods 3 and 4 have a substantially
H-shaped profile, the lower ends of the side webs of said H being
provided with inwardly and upwardly extending end webs 9. The upper
end of the side webs are provided with protrusions 12 extending
towards each other. The end webs 9 just touch each other so that a
certain clamp effect is provided between them when a reproduction
or a poster is moved into the space between them. Between the
protrusions 12 there is a suitable distance so that the suspension
portions 7 will not wedge in the groove 6. The H-profile may have a
thick horizontal transverse web or two relatively thin webs 13a and
13b which are arranged spaced and in parallel. The cover rod 5
contacts the external side of the clamp rod in tight manner. At the
bottom of the cover rod there is provided a longitudinal slot 14 so
that the reproduction or poster may be moved through the rod 5. The
suspension portions which may be moved to and fro in the groove 6 -
confer FIG. 1 - may be shaped as shown in FIG. 4. Each suspension
portion 7 is provided with a shoe which may slide in the groove 6.
This shoe is by means of a connection portion 15 connected with a
suspension plate 16 having a hole 17. When the suspension device is
to be arranged on a nail in a wall, both suspension portions are
moved onto the nail. The suspension portion 7 normally has such
thickness that its rear surface 18 will extend behind one edge of
the clamp rod or register with this edge. This is clearly seen when
the suspension portion of FIG. 4 is used in connection with the
suspension rod of FIG. 3 - confer below.
In FIG. 3 is shown a second embodiment of the profile of the clamp
rods. The shown profile is rather thick for which reason there is
sufficient space for two grooves 6a and 6b. Hereby it is always
possible to arrange a suspension portion quite close to such edge
of the profile which is adjacent to the wall. The upper transverse
web in the middle of the H is provided with a bulging part 20. This
bulging part cooperates with the protrusions 12 so as to define the
grooves 6a and 6b. The profile of FIG. 3 is particularly applicable
for heavy reproductions, e.g. such reproductions which are provided
with a protecting clear sheet or foil.
As far as side webs and end webs are concerned the profile of FIG.
3 is constructed in nearly the same manner as the profile of FIG.
2. To ensure clarity of FIG. 3 no cover rod is arranged on the
profile. The cover rod which is arranged in connection with the
profile of FIG. 3 is similar to the cover rod used in FIG. 2, but
is only somewhat thicker. The cover rod is in tight contact with
the shown profile.
Possibly clamp rods 21 and 22 may be arranged between the frame
portions 1 and 2, said clamp rods having constant lengths. An
example hereof appears from FIG. 5. The frame as shown has a
constant height, but the width may be changed.
When the suspension device only comprises an upper and a lower
frame portion - as shown in FIG. 1 - these portions will be
arranged symmetrically, the concavity of the cover rod of the upper
frame portion facing downwards, while said concavity of the lower
frame portion facing upwards.
The clamp rods and cover rods shown in the figures may be made of
different materials, preferably of plastics material.
When the suspension device of FIG. 1 is to be used, the width of
the reproduction or poster 10 is first measured. Then the clamp
rods 3 and 4 are drawn out of the cover rod 5 to such extent that
the distance from the left end of the clamp rod 3 to the right end
of the clamp rod 4 corresponds with the width of the reproduction
or poster. Then the frame portion 2 is adjusted correspondingly.
The reproduction or poster is then moved through the slot 14 and
into the space between the end webs 9 (FIG. 2). Then the distance
between the suspension portions 7 is adjusted so that it
corresponds with the distance between the two nails which have
previously been driven into the wall. Thereafter the reproduction
or poster is suspended on the nail.
The above described embodiments of the suspension device only
illustrate the invention. They do not limit the scope of
invention.
