[0001] The present invention relates to a display device and relates particularly, but not
exclusively, to an advertising device for attachment to a post or pole.
[0002] It is commonplace to attach display devices or signs to posts or poles. For example,
small road signs and road sign like advertising signs are regularly attached to lampposts.
An example of such a display device and attachment means therefor is shown in Figures
1 and 2. A sign 1 is attached to a post or pole 2 by attaching means 3 which are held
in engagement on the post 2 by tightening means 4.
[0003] The size of the sign 1 is an important factor in trying to draw attention to the
sign. It is generally the case that the larger the sign the greater the attention
drawn to it. However, a larger sign 1 will exert greater forces on post 2 and attaching
means 3 when, for example, wind blowing from directions A or B act upon it. Such forces
may exert a turning force on sign 1, which in turn acts on post 2 through attaching
means 3. If attaching means 3 are not attached sufficiently tightly sign 1 will rotate.
If a force of sufficient magnitude is applied to attaching bands 3 this force may
cause damage to post 2, for example to the surface coating on post 2, or under a more
extreme force the structure of post 2 itself may be weakened. The application of such
forces may also apply a bending force to post 2. This may either weaken the connection
between the post and the ground, for example by enlarging the hole in which the post
sits, or may cause a structural fatigue within the post, in particular around the
junction between the post and the ground.
[0004] The sign shown in Figures 1 and 2 is also only capable of displaying information
in a single direction, when it may be necessary or at least advantageous to display
information to persons in all directions from the post.
[0005] Preferred embodiments of the present invention seek to overcome the above described
disadvantages of the prior art.
[0006] According to the present invention there is provided a display device for attachment
to an elongate support, the device comprising:-
at least one display means adapted to encircle said elongate support;
a plurality of support members adapted to form the or each display means into a respective
hollow structure;
a plurality of engaging members adapted to engage said support; and
connecting means for connecting said display means and/or at least one said support
member to at least one said engaging member.
[0007] By providing a display device having a display means supported around an elongate
support by support members and connected to said elongate support by engaging members
and connecting means, the advantage is provided that a single display device which
is viewable from all directions can be provided. Such a display device also has the
advantage that a wind blowing against the device has a straightforward aerodynamic
route enabling the wind to move around the device and exerting forces significantly
lower than the forces exerted by a similarly sized sign of the prior art. As a result,
the damage caused to a post or pole carrying such a display device is significantly
less than would be expected if an equivalent sign of the prior art would be used.
Furthermore, this force is generally identical from all directions for a given wind
speed.
[0008] The elongate support may be a flagpole or lamppost.
[0009] In a preferred embodiment said display means is formed from a sheet of flexible material.
[0010] By providing the display means in the form of a sheet the advantage is provided that
a small weight and volume of material can be used to produce a large display device.
Thus the display device is very lightweight further reducing the forces (in this case
the force of gravity) that are applied to the post and therefore further increasing
the size of display that can be created. Furthermore, when not in use the device can
be folded into a compact form thereby taking up a minimal amount of space during storage
or transportation.
[0011] In a preferred embodiment the sheet has a first edge, and a second edge adapted to
engage said first edge thereby forming said hollow structure.
[0012] Having first and second edges which are able to engage each other provides the advantage
that if, for instance, a cylindrical tubular display is to be formed, during the process
of erecting the device, the cylinder may be formed around the elongate support rather
than inserted over one end. Therefore for very long elongate supports or such supports
having large obstructing means located above the position at which the display device
is required, the process of erecting the display device is made significantly easier.
[0013] The first and second edges may engage each other by means of at least one hook and
eye fastener and/or at least one button and/or at least one zip fastener.
[0014] In a preferred embodiment the flexible material is formed from durable woven or knitted
plastic material.
[0015] In a preferred embodiment the or each said support member is substantially circular
in use.
[0016] Providing circular support members in turn provides a display device having circular
cross-section. Such a cross-section provides the most aerodynamically efficient shape
from all directions.
[0017] In a preferred embodiment at least one said support means is a flexible, elongate,
tubular member.
[0018] By using flexible elongate tubular members for the support means of the display device
the advantages provided that lightweight support members which form naturally into
circular members.
[0019] In another preferred embodiment the dimensions of each support member in use are
substantially the same.
[0020] This provides a tubular display device of uniform cross-section.
[0021] In a preferred embodiment at least one said engaging member is adapted to engage
said elongate support by means of friction.
[0022] By engaging the elongate support by means of friction it is not necessary to make
any permanent alteration to the elongate support. Furthermore because of the reduced
forces applied to the device, which in turn apply these forces to the elongate support
at its surface, the frictional force required to maintain the device at a predetermined
position is significantly less than those of the prior art, and therefore the damage
to the elongate support will be reduced.
[0023] In a preferred embodiment said connecting means comprises at least one elasticated
cord.
[0024] By providing elasticated connecting means the advantage is provided that at least
some of the force which may be applied to the device by the wind is absorbed by the
resilient means thereby further reducing the force applied to the engaging members.
Furthermore, where the wind is able to cause the device to vibrate, due to a harmonic
vibration being created by the wind speed, the majority of this vibration will be
absorbed by the connecting means and the elongate support will remain unaffected.
[0025] In another preferred embodiment the connecting means further comprise clamping means
for attaching the connecting means to at least one said engaging member.
[0026] Preferred embodiments of the invention will now be described by way of example only,
and not in any limitative sense, with reference to the accompanying drawings in which:-
Figure 1 shows a front elevation view of a sign of the prior art;
Figure 2 shows a side view of the sign of Figure 1;
Figure 3 is a perspective view of a display device of a first embodiment of the present
invention;
Figure 4 is a perspective view of a display device of a second embodiment of the present
invention;
Figure 5 is an exploded view of the display device of Figure 3;
Figure 6 is a perspective view of a display device of a third embodiment of the present
invention; and
Figure 7 is a perspective view of a display device of a fourth embodiment of the present
invention.
[0027] Referring to Figures 3 and 5 a display device 10 for attachment to an elongate support
or post 12 has a display means 14 adapted to encircle the post 12 and a plurality
of support members 16 adapted to hold the display means 14 in a tubular arrangement.
The display device 10 also has a pair of engaging members or clamps 18 which engage
the post 12 by means of frictional force. Connecting display means 14 to the clamps
18 are connecting means 20 which are themselves formed from elasticated cord 22 and
clips 24.
[0028] Display means 14 has sleeves 26 into which support members 16 are inserted. Display
means 14 is in the form of a sheet having opposing first and second edges 28 and 30
adjacent which hook and eye type fasteners (known as velcro) 32 are attached allowing
the engagement of the first and second edges 28 and 30. Support members 16 are formed
from flexible tubular material and have bungs 34 in opposing ends thereof allowing
the opposing ends to be joined together. Display means 14 has holes 36 located therein.
[0029] In order to erect display device 10, clamps 18 are attached at a suitable distance
apart on post 12. Display means 14, in the form of a flat sheet, has support members
16 inserted through sleeves 26. Display means 14 and support members 16 are then bent
such that first and second edges 28 and 30 of display means 14 can be engaged such
that velcro 32 can form an attachment between these edges. Bungs 34 allow opposing
ends of support members 16 to remain engaged and provide structural support for display
device 10. For ease of construction the above engagements are performed around post
12 such that the display means 14 encircles the post 12.
[0030] The display means 14 and support members 16 are connected to clamps 18 by connecting
means 20. Elasticated cords 22 are tied through holes 36 and clips 24 attach the cords
22 to clamps 18. If the cords 22 are not sufficiently tight to maintain the display
device 10 in a suitable location or under sufficient tension to for instance prevent
the device 10 banging against post 12, clamps 18 can be loosened and repositioned
such that the tension is correct.
[0031] Figure 4 shows an alternative embodiment of the invention in which support members
16 of differing lengths are used, along with a suitably cut display means 14 such
that a truncated conical display device 10 is formed.
[0032] In Figure 6 additional connecting means 20 are used so as to provide additional tension
within the device 10. This arrangement would typically be used in areas regularly
experiencing strong wind where an additional force is required to prevent the device
10 from contacting post 12. Such an arrangement might also be used where the display
device is intended for long term display, the additional connecting means reducing
the tension within any one connecting means and thereby increasing the life expectancy
of the elasticated material in the cords 22.
[0033] Figure 7 shows an example of a longer device 10.
[0034] The above described display devices might typically be used for advertising. For
example, a cylindrical device 10 could be decorated such that it represents the get-up
of a cylindrical product or product sold in cylindrical packaging. The device 10 may
also be used to display information through 360 degrees of viewpoints.
[0035] It will be appreciated by persons skilled in the art that the above embodiment was
described by way of example only, and not in any limitative sense, and that various
alterations and modifications are possible without departure from the scope of the
invention as defined by the appended claims. For example, the support means need not
necessarily be formed in use into an annular form, and a rectangular formation, for
example, would provide many of the advantages over the prior art.
