Abrégé anglais

A poster mounting apparatus includes an elongate mounting member (2) in the
form of a hinge with a longitudinal hinge axis, having a movable leaf (9) and
a fixed leaf (11) which is securable to a support. The movable leaf (9) has a
longitudinal groove (23) for receiving a bar-like portion (28) provided on an
edge of a poster (24) and is pivotable about the hinge axis between an open
position, in which the bar-like portion can be inserted into and removed from
the groove (23), and a closed position, in which the groove (23) opens in a
direction away from the main part of the poster (24) so that the bar-like
portion is retained in the groove. The movable leaf (9) is releasably
connectable to the fixed leaf (11) to maintain the movable leaf in the closed
position. An elongate edging element (26) for the poster comprises an
extrusion having a strip- like portion (27) for connection to an edge portion
of the poster and a bar-like portion (28) for connection to the poster
mounting apparatus. The strip-like portion (27) comprises a first plastics
material, e.g. polyurethane, and is relatively flexible and the bar-like
portion (28) comprises a second plastics material, e.g. PVC, and is relatively
stiff.

Poster Mountin~
This invention relates to the mounting of posters. In this specification the
word "poster"
is used as a general term and includes any form of sheet material bearing an
image,
artwork, or lettering, e.g. an advertising banner.
It is known to mount a poster on a mounting apparatus fixed to a support such
as a wall,
a light box, or the side of a vehicle. W003/049069 discloses such an
apparatus. With
that apparatus, the edges of the poster have to be provided with beads by
wrapping an
edge portion of the poster around a bar.
The invention provides a poster mounting apparatus including an elongate
mounting
member in the form of a hinge with a longitudinal hinge axis, the hinge having
a
movable leaf and a fixed leaf which is securable to a support, the movable
leaf having a
longitudinal groove for receiving a bar-like portion provided on an edge of a
poster, the
movable leaf being pivotable about the hinge axis between an open position, in
which
the bar-like portion can be inserted into and removed from the said groove,
and a closed
position, in which the groove opens in a direction away from the main part of
the poster
so that the bar-li.ke portion is retained in the groove, the movable leaf
being releasably
connectable to the fixed leaf to maintain the movable leaf in the closed
position.
The present invention also provides an elongate edging element for a poster,
comprising
an extrusion having a strip-like portion for connection to an edge portion of
the poster
and a bar-like portion for connection to a poster mounting apparatus.
The invention will be described fiuther, by way of example only, with
reference to the
accompanying drawings, in which:
Figure 1 is a schematic front view of a poster mounting apparatus;

Figure 2 is a section on line II-II in Figure 1;
Figure 3 is an enlargement of detail III in Figure 2;
Figure 4 is a section on line IV-IV in Figure 1;
Figure 5 is an enlargement of detail V in Figure 4;
Figure 6 shows the fixed leaf of the hinge illustrated in Figure 4;
Figure 7 shows the movable leaf of the hinge;
Figure 8 is a perspective view of a spring clip;
Figure 9 is a section through an elongate edging element for a poster; and
Figure 10 is a section through another elongate edging element, for the top
edge of the
poster.
The poster mounting apparatus shown in Figure 1 is in the form of a frame
attached to
one or more vertical supports (not shown). The frame is made up of four
elongate
mounting members 1 to 4: a top member 1, a bottom member 2, a left-hand member
3,
and a right-hand member 4. The apparatus is intended for use with posters
several
metres long (e.g. 6 to 14 m) and several metres high. The mounting members 1
to 4
have substantially the same width and depth (thickness) and are connected
together at
mitred edges 5, which contributes to the stability of the apparatus.
The top mounting member 1 (Figures 2 and 3) consists of a single metallic
extrusion (in
particular made of aluminium) having a web 6 for attachment to a support and
an upper
body 7 with an undercut groove 8 which is open downwardly to receive an edging
element provided on the poster as described below.

The bottom mounting member 2 is in the form of a hinge with a longitudinal
hinge axis.
The hinge has a movable leaf 9 and a fixed leaf 11, which is fixed to a
support. Both
leaves 9, 11 are metallic extrusions (in particular made of aluminium) and
they are
permanently connected together so that there is no risk of the movable leaf 9
being
removed and damaged or lost in normal use. The fixed leaf 11 has an upper body
12
with a cylindrical bore 13 which retains a cylindrical hinge pin 14 integral
with the
movable leaf 9. The upper body 13 of the fixed hinge 11 is connected by a web
16 to a
lower body 17 having a longitudinal recess 18 for receiving a longitudinal
projection 19
formed on a lower body 21 of the movable leaf 9. The recess 18 has trapped
within it a
number of spring clips 22 for releasably retaining the projection 19 in the
recess 18.
The leaf 9 is movable from the closed position shown in Figure 4 to an open
position in
which it extends roughly at right angles to the web 16 of the fixed leaf 11
and in which
a bead provided on the edge of a poster can be easily inserted into or removed
from a
groove 23 (as described below). In the closed position of the movable leaf 9
the groove
23 opens in a direction away from the main part of the poster.
The side of mounting members 3, 4 are similar to the bottom mounting member 2,
are
parallel to each other, and are arranged mirror - symmetrically.
A poster 24 is indicated in chain dotted line in Figures 2 and 4. Each of the
bottom,
left-hand, and right-hand edges of the poster is provided with an elongate
edging
element 26 along almost the whole of its length. The edging element is
constituted by
an extrusion having a strip-like portion 27 for connection to an edge portion
of the
poster 24 and an oblong bar-like portion 28 serving as a bead for insertion
into the
groove 23 in the movable hinge leaf 9. The edging element 26 is made of two
different
plastics materials, which are extruded together. The strip-like portion 27 is
resiliently
flexible and tear-resistant and is made of an elastomeric material, in
particular
polyurethane. The bar-like portion 28 is relatively stiff and is made of a
rigid or semi-
rigid plastics material (in particular PVC). On one side of the strip like
portion 27 is
provided with a thin adhesive layer 29 extending from the free edge of the
portion 27 up
to a longitudinal rib 31 against which the edge of the poster can abut.

In the present embodiment the layer 29 is made of PVC and is intended to be
connected
to the poster by high-frequency welding. However, it could be made of any
convenient
adhesive material, such as a melt adhesive or a contact adhesive, optionally
protected by
a temporary covering foil.
The top edge of the poster is provided with an edging element 32 which is
similar to the
element 26, except that it has a bar-like portion which is of round cross-
section.
To mount the poster 24, the edging elements 26 and 32 are fixed to the rear
surface of
the edge portions of the poster. The round bar-like portion 33 along the other
edge of
the poster is then slid along the groove 8 in the top mounting member 1,
starting at one
end. The left-hand and right-hand mounting members 3 and 4 are opened and the
respective strip-like portions 27 at the left and right-hand edges of the
poster are
inserted into the respective grooves 23, and the bottom mounting member is
also
opened and the corresponding bar-like portion 28 is inserted into its groove
23. The
movable leaves 9 of the left-hand, right-hand, and bottom mounting members 2
to 4 are
moved to the closed position in any convenient order, thereby applying tension
to the
poster 24 and causing the bar-like portions 28 to be retained in the
respective grooves
23.
