Advertising device
RUDOLF JBSOKA
G/ 40429
s nven on re a es o an a ver s ng
device adapted to be internally illuminated and particularly to such a device comprising a support structure and a cover of a light transmitting material.
In the past illuminated advertising devices of this type have been usually produced by shaping or welding a support of galvanized sheet metal and attaching
the cover thereto by any of a number of methods. Illuminated advertising devices of this kind suffer from the drawback that the cover cannot be mounted on the support structure from the front, which makes it difficult or impossible
to mount a number of such devices side by side to form
large-area illuminated advertising installations, in
addition to which maintenance operations (cleaning and
repairs) are difficult to perform, although the cleaning is the very task which, in the case of these known devices, has to be carried out with particular frequency and
thoroughness.
The purpose of the invention is therefore to adopt, with an advertising device of the type described, measures by which the erection and assembly will be facilitated, both in the first instance and in the case of subsequent maintenance operations, and also to render the device
far less sensitive, from the outset, to weather influences, such as humidity anddirt.
According to the invention, an advertising
device, which is adapted to be internally illuminated,
comprises a tray-like support structure; an inwardly
directed bead which is carried by, and extends right round, the edges of the support structure and which at each of
at least two corners of the structure has a smaller depth than elsewhere; and a light transmitting cover having on its side walls an outwardly opening groove adapted to receive the bead in order to hold the cover in position; the reduction in depth of the bead at the said corners facilitating entry of the cover walls within the bead until the bead is received in the
groove.
It is desirable that the bead on the support structure should also take the form of an outwardly opening U-groove engaging the U-groove- of the cover, and that its depth should constantly decrease as it approaches each corner, starting at distances from
the corners. In addition, the edges of the
support structure are preferably bowed inwards, thus being elastically prestressed inwardly when installed in the straight position.
In order to ensure that any liquid which has entered the gaps between the U-groove of the cover and the bead on the support structure will not find its way into the interior of the advertising device, thus carrying particles of dirt into the latter and causing contamination which is visible from the outside, the groove of the cover is preferably formed with a beading integrally extending from the base of that groove. In particular, the beading may be so formed that a narrow slit connects the interior of the beading with the groove of the cover. The beading is thus circular or tear-shaped, for instance, in cross section.
The trapping of liquid may be aided by a notch
cover and in the vicinity of the front panel and
parallel to this latter. That notch prevents any
rainwater running down the front panel from causing
any uncontrolled deposits of dirt on the lower wall of the cover (and of the support structure) by carrying
dust and particles of dirt with it. · Water of this
kind is kept away, together with any extraneous matter carried with it, by the notch, in which the dirt is deposited the resulting dark streak parallel to the front disc does not detract from the appearance of the installation.
In a further development of the invention,
projections and/or cavities may be formed on the side walls of the support structure and can be interconnected with similar elements on an adjacent device or devices, in order to form larger installations. This enables large-area advertising installations to be formed by placing a number of individual devices side by side. As a rule, one of two abuttin side walls of the support structure is provided with grooves and the other with tongues, this applying particularly to rectangular devices of which the upper and left-hand walls may be provided with grooves and the right-hand and lower side walls with tongues. Particularly with devices which are triangular in plan or which are circular or part circular in plan, however, grooves may be provided on all side walls, shaped connecting
bars serving to interconnect adjacent grooves of devices next to each other.
In particular, the system can be so arranged that the projections or cavities are situated at a fixed
universal combination of advertising devices to be obtained, even if they differ in their individual shapes.
The invention will be more readily understood by way of example from the following description of an illuminated advertising device in accordance therewith, reference being made to the accompanying drawings, in which
Figure 1 is a cross sectional view of the
advertising device;
Figure 2 is an exploded view, in perspective, of the left-hand upper corner of the advertising device*,
Figure 3 is a reduced perspective view of the advertising device showing the operation of mounting the cover on the support structure;
Figure is a perspective view of the right-hand lower corner of the support structure;

Figure 8 is an installation made up of a number of basic elements and taking the form of an oval in
plan view;
Figure 9 shows another advertising installation made up of different basic devices, also in plan view;
Figure 10 shows the construction of the plugs and sockets for fluorescent tubes;
Figure 11 shows in section the addition of a sealing foil to the cover;
Figure 12 is a section on the line XII-XII of Figure 11, and ,
Figures 13 and 1 show in section and in plan a further form of sealing foil.
The advertising device shown in the drawings consists essentially of a tray-like support structure 1, deep drawn from a sheet or plate of resiliently deformable plastic, and a transparent or translucent cover 6 which carries the advertising matter. A bead in the form of a U-shaped groove 2 is provided around the entire edge of Ithe structure 1. As may be seen from the upper part of Figure 2, the U-groove 2 is drawn in at all four corners of the installation support 1, so that starting at a distance from each corner the groove constantly decreases in
depth as it approaches that corner. Furthermore, the U-groove 2 of the support structure 1 and, to a certain ' extent, the side walls are drawn inwards, i.e. they are bowed inwardly, their shape being that shown by broken lines in Figure when they are in the position of rest.
The cover 6 is formed with an outwardly opening U-shaped groove 5 at the free ends of the side walls; when the cover 6 is mounted on the structure 1 with bead 2 in the groove 5> the edges of the supporting structure are forced into the operational straight position, the
resilience of the structure causing the edges to be
prestressed inwardly against the cover and the bead 2
to be pressed elastically into the U-groove 5·
When the cover 6 is mounted on the support
structure 1, the free limb of the U-groove 5 is first of all (as shown in Figure 3) moved into position behind the corresponding U-groove 2 of the support structure 1 at one end, after which the cover 6 is closed, in the
direction shown by the arrow in Figure 3. In this
process the inwardly biased edges of the structure 1
can be opened out elastically and the edges of the
cover 6 can be correspondingly pressed elastically
inwards to the extent required to ensure that the free limb 4 of the U-groove 5 engages the rear of the U-groove 2 on the structure 1, along the remaining side walls. In the zone of the corners 3» which cannot of course
be stretched outwardly, the reduction of the depth of the U-groove 2, in conjunction with the reducing o the corners 7 of the limbs 4, as shown at the bottom of Figure 2,
ensures that the corners of the cover 6 can move into
position behind the U-groove 2 and engage the support
structure 1.
The U-shaped groove 5 of the cover 6 is formed with an integral beading 9 which extends from the base 8 of the groove over the entire length of that groove. The
cross section of the beading 9 is approximately
tear-shaped, with its interior 10, which serves for the removal of any water which has entered, connected by a narrow slit 11 with the U-shaped groove 5· By capilliary action, the limited width of the slit 11 assists in drawing water into the interior 10 if any has found its way in between the grooves 2 and 5· That water runs in the beading 9
jto the deepest point, where drain holes may be provided, 1
A notch 1 is formed in the side wall 15 of the cover 6 and extends right round the cover parallel to
the front panel 12 of the cover to intercept any
dirty water that may be received by the cover and to
deposit the particles of dirt as described above.
The back of the support structure 1 carries two sets of elongate hooks 15, 16 (Figures 1 and 7), the hooks of the two sets being mutually at right angles, so that the advertising device can be mounted optionally on
either vertical or horizontal bars 17, as shown in
broken line in Figure 7- Because of the disposition
of the hooks 15, 16 as shown in Figure 7, the hooks
of one set do not obstruct the raounting of the other set on the bars 17» Figure 1 shows how Z- or S- shaped metal reinforcements 18 are inserted into the hooks 15, 16.
The edge of the free limb ,of the U-shaped
groove 5 on the cover 6 is provided with a lip 19
(Figure 6), which is made of elastically resilient
material and which forms a prolongation of the limb 4·.
The lip 19 may if necessary be formed at the same time
as the limb , which is made of a harder material.
The upper and left-hand side walls of the supporting structure 1 are formed with dovetailed grooves 20 which
are
are shown at the top of Figure 2 and/complementary to
correspondingly dovetail-shaped tongues 21 on the lower and right-hand side walls (Figure 4). These grooves and tongues enable adjacent advertising devices to be
connected together. As the distance between each corner and the centre of the first groove 20 or first tongue 21
each two successive tongues 21 is invariably 12.5cm, two of the advertising devices can be interconnected in an aligned disposition or offset relative to one another by multiples of 12.5cm.
Figures A-D show different versions of this method of connecting together the devices. While
Figure again shows the dovetail-shaped connections of Figures 2 and 4-, the profile of the tongue in Figure 5B is substantially circular and, if the material is
suitably chosen, can be caused to snap into position instead of being merel inserted. As distinct from the examples illustrated in Figures 5A, B and D, the method of connection shown in Figure 5C cannot be subjected to tractive stress; this, however, is frequently unnecessary, because it is only necessary to transmit vertical aligning and supporting forces between the individual advertising devices of an installation. Figure 5^ shows the
combination of two advertising devices when two grooves 20 are situated opposite each other. In this case, the connection is effected by a double dovetail bar connector 22.
Figure 8 shows the basic shapes for making up illuminated advertising installations from individual devices on the module principle. The basic shapes are squares and rectangles, together with the necessary triangles, as well as parts of circles and parts of
rings. If the shortest side occurring has a length of _a, then the smallest rectangular element is a square of which the other side has a length of ^. In the next greater module, the length of the side, 2> is twice as grea as the basic length a; generally the length b
there is a triangular element, as shown for the case a - b£» on the right-hand side in Figure 8, by
chain line 23.
The elements in Figure 8 which have the
shape of a quarter of a circular ring have an external radius R twice as great as the internal radius _r,
which in its turn is equal to the length a of a side.
Generally the radii of a part-annulus are given by
R = r+na
For a part-circular device, the radius r is given by
r = na
The installation shown in Figure 9 consists of three devices of two basic shapes, i.e. two
quarter-circle elements and one rectangular element of which the longer side b£ is equal to twice the basic length ja of a side. In the same manner, other installations can be made up of triangular and part-ring devices.
Needless to say, the dimension &_ may be smaller than shown in- Figures 8 and 9> so that the square element a - b^ in Figure 8 may consist of four square devices a/2 - b1/2 or of two rectangular devices a/2-b^.
Contained within, and carried by, the support structure 1 are fluorescent tubes, shown diagramatically in Figure 1, for the illumination of the advertisements on the cover 1. The mounting of the tubes is shown in detail in Figure 10 where one of the tubes is represented at 2 and where a socket for that tube is indicated at 23. The end of the tube 24 has pins 25 with thickened heads 26,
which move into position behind resilient inserts 2? in the socket 23 end which cannot come out of the socket 23 unless subjected to exceesive traction. A protective cap
28 made of rubber or similar material surrounds the
socket 23 and rests tightly against the glass body of the fluorescent tube by a beading 29. T e protective cap 28 can, if necessary, be perforated to give passage to a cable 30.
Figures 11 to 14 show the construction and arrangement of a foil 31 of transparent material which is secured to the limb of the U-shaped groove 5 of the cover 6 and which provides a dust-proof and water tight seal separating the cover 6 from the support structure 1. Both the version shown in Figures 11 and 12 and that shown in Figures 13 and 14 are provided with preformed
protrusions. In Figures 11 and 12 these consist
of a multiplicity of stabilizing corrugations 32 of which the depth is not as great as that of the bent edge 33 affixed to the limb 4 of the U-groove 5·
In Figures 13 and 14 the protrusions have a pyramidal profile 34, which offers the advantage of
ensuring an even distribution of the light emanating » from the fluorescent tubes.
