Description

Display Device Field of Invention

This invention relates to a display device particularly for use on vehicles Background to the invention Several types of display device for use on vehicles are known and some of these act in a way similar to a wind sock If it is desired to provide a surface for the display of information on the side of a wind sock several problems are encountered

For example, wind socks typically used on air fields for indicating wind direction consist of a fabric bag, with the shape of a cone The fabric bag is open at both ends and is erected on a tall pole with the wider end of the cone nearest the pole The wider mouth of the cone is provided with a support so that this mouth always remains open and does not close up as the fabric sides of the cone fall together This support may be provided by a rigid structure placed around the wider mouth of the cone This support also forms the mounting point by which the windsock is attached to a pole

In this way air is always free to flow through the cone so that the pressure from the wind distends the fabric sides of the cone The cone is free to rotate about the pole so that the wind direction is indicated by the position of the cone about the pole One problem with these kinds of wind sock is that when the sock is deflated the fabric tends to hang down creating a crease near the support The fabric is put under greater strain at this point and tends to rip or tear

A further problem is that if no support is provided around the mouth of the cone the sides of the cone fall together This means that air currents can simply make the fabric twist and turn about rather than entering the cone and distending the fabric sides to give the cone an inflated structure In this way any information that is displayed on the side of the wind sock is not always visible or presented on a clear and even surface

Known wind socks are also problematic in that they must be constructed from hard wearing anti-rip fabric This is necessary to prevent the wind sock from breaking up under the forces of the wind The wind sock must also be weather proof and able to withstand the elements These types of wind sock are therefore expensive to manufacture and costly to replace if it is desired to use them to display advertising material and the like, which is often changed Another problem with known wind socks is that instability is often produced with turbulent air currents That is, the wind sock tends to twist and turn about and be pulled in different directions This increases the risk of the fabric tearing and becoming worn Also the wind sock is prevented from forming into its cone structure and may become tangled up in itself This may mean that it is necessary to untwist the cone and remount the whole wind sock This is not only time consuming but means that the wind sock is out of action for some periods

Wind socks, similar to those used on airfields, are also known for use on yachts and other moving vehicles both to indicate wind direction and to provide decoration For example, wind socks made from coloured fabric are known which have strips of fabric at the end of the cone to act as streamers This type of wind sock has similar disadvantages as those used on air-fields For example they must be made from expensive anti-rip fabrics and they become unstable during turbulent air flows However, these problems are particularly accentuated when it is desired to use the wind sock on a moving vehicle This type of wind sock must be able to withstand very high wind speeds together with turbulent air flows created by the motion of the vehicle The support structure around the mouth of the cone is relatively heavy and has its own inherent drag This presents problems when it comes to mounting it on a vehicle Known wind socks have used expensive anti-πp fabrics in order to cope with these conditions The problems of instability are also increased because of the frequent turbulent air flows Another problem involves the means by which the wind sock is attached to the vehicle and how the mouth of the cone can be held open If the mouth of the cone is held open by using a rigid support this is likely to break under the forces of the wind One further problem with the known wind socks is that they have typically been attached to the vehicle using means which is not adequate to both prevent the wind sock from coming off and to prevent the wind sock from becoming unstable and twisting and turning about

Another problem with the use of windsocks on vehicles is that it may be desired to position the windsock on a retractable pole, aerial or similar structure However, known windsocks are not suitable for use on retractable poles, aerials or the like

One disadvantage with known windsocks is that it is difficult to display a message or coloured image as a form of communication on the windsock Known windsocks do not have a flight pattern that is sufficiently stable or have an ability to inflate sufficiently readily to allow such messages to be read Known windsocks are designed to be inflated by the wind and so to depict the wind condition They require the natural element of the wind to be present for inflation Known windsocks are problematic in that they are unable to inflate when no wind is present and are not designed to inflate using air currents created by the motion of a vehicle It is accordingly an object of the present invention to provide a display device particularly suitable for use on moving vehicles which overcomes or at least mitigates one or more of the problems noted above Summary of the invention According to the first aspect of the present invention there is provided a display device for use on a moving vehicle, said display device comprising -

(i) a flexible, inflatable tube with a mouth and a tail end, said tube being adapted such that air currents can flow through the tube and in doing so cause the tube to inflate, (n) a reinforced collar region around the mouth of the tube,

(in) a first attachment means being an integral part of or adapted to attach to a vehicle, (iv) a second attachment means adapted to attach the collar region of tube to the first attachment means on the motor vehicle, and wherein the sides of the tube are adapted to display advertising or other display material This provides a simple, inexpensive device for the display of advertising material in an eye-catching manner

Preferably, the first attachment means comprises a vehicle aerial Most cars have radio aerials and they are a convenient fixing point

In an alternative embodiment the first attachment means comprises a mounting element adapted to be secured to a vehicle, said mounting element being further adapted to incorporate a mounting post This feature enables the device to be attached to vehicles without aerials Preferably, the second attachment means comprises one or more holes in the collar region of the tube

In an alternative embodiment the second attachment means comprises a fixing means adapted to connect the first attachment means to the reinforced collar region of tube

Preferably the fixing means comprises an elastic strap

In a particularly preferred embodiment the fixing means comprises a three- pronged connector, the end of each prong being adapted to engage in a hole in the reinforced collar and the region of the collar furthest from the end of each prong being adapted to attach to the first attachment means

Preferably the reinforced collar region is formed from a strip of plastics material fixed around the mouth of the tube, such that in use when the vehicle is stationary the tube is substantially collapsed and when the vehicle is in motion the mouth of the tube is held substantially open and the display device is deployed to provide a surface for display of advertising material and the like When the vehicle starts to move the mouth of the tube is held open and air currents enter the tube and inflate the tube Problems of instability are reduced, that is the tube is deployed in a stable position and does not tend to twist and turn about despite the presence of turbulent air currents that may be created by the motion of the vehicle Preferably the reinforced collar region comprises a tubular channel extending substantially around the circumference of the mouth of the tube, said channel incorporating a reinforcing strip

Alternatively the reinforced collar region comprises a region of increased material thickness compared to the main body of the tube Description of the drawings

Embodiments of the present invention are described below by way of example only These examples represent the best ways of putting the invention into practice that are currently known to the Applicant although they are not the only ways in which this could be achieved

The display device is adapted for use on a vehicle where the term vehicle has a broad meaning any type of vehicle capable of movement including, for example, cars, boats, ships, bicycles, commercial vehicles and motor cycles and the like.

As shown in Figure 1 , an embodiment of the display device includes a tube

1 which is formed into a conical shape although many other shapes could be used, for example, a tube with parallel sides or a bottle shaped form (see below). The tube 1 is manufactured from a flexible, light weight material such as fabric, plastics material or in a preferred embodiment polythene. The material may also be of a varying gauge. As shown in figure 1 the tube has a mouth end 2 and a tail end 6.

Advertising material, patterns, text and the like can be printed onto the side of the tube 1. Preferably the material of the tube and the print are such as to be able to withstand outside elements for a life-span of at least 5 to 6 weeks or longer as required.

The tube is attached to a fixing location or attachment means on the vehicle. For example, the fixing location may be an aerial, boat stay or similar structure. Also, by using several different types of fixing a wide variety of locations are possible. For example, windows, bicycle handlebars, frames, stays, wing mirror fittings, car roofs, bonnets and decking.

A second fixing or attachment means is required to fix the tube onto the vehicle yja the first attachment means. As will be appreciated from the following description, both these fixings can take a wide variety of forms. For example, the second fixing may consist of holes or slots, 3 and 4 (figure 3) positioned in the tube near the mouth 2. The display device can then be attached to an aerial, boat stay or other similar structure by threading the aerial through both holes 3 and 4 or alternatively through only one of these holes as shown in figure 6. In the case where only one of the holes is used it is possible to only make one hole in the tube. In this example, the second attachment means comprises a resilient retaining strip adapted to connect the tube to the fixing location. In a preferred embodiment, the resilient retaining strip has at least two holes one at each end of the stπp which are adapted to stretch over and locate with an aerial or similar structure Figures 9 and 10 show examples of retaining strips. The retaining strip is placed onto the aerial or similar structure as shown in figure 11 and acts to hold the tube securely in place The term resilient retaining strip also encompasses a plastic strap such as that shown in Figure 28. Figure 10A also shows another alternative retaining strip. This is in the form of a washer made from a resilient material such as highly elastic rubber that is adapted to stretch over and locate with an aerial or similar structure. It is possible to use either a single such washer type retaining strip or two or more of these pieces.

Considerable force is generated around the mouth of the tube when the vehicle moves at speed A reinforced collar may also be provided substantially around the mouth of the tube. This may take the form of increased gauge material around the mouth of the tube as shown in figure 3. Alternatively, as shown in figure 4 a collar 7 can be placed around the mouth of the tube 1 as shown to provide extra strength and support in this region. This collar 7 may be placed either around the inside or the outside of the mouth Holes or slots 8 and 9 are also provided in the collar 7 so that they may be superimposed on the holes or slots 3 and 4 on the tube 1.

Alternative collars are shown in figures 23, 24, 25, 36 and 37.

A collar may also be provided by a strap such as those shown in figures 7 and 8. These straps can be placed around the mouth of the tube and held in place using a channel such as that shown in figure 1. In the cases where straps such as those shown in figures 7 and 8 are used the tube is attached to the aerial or other similar structure using holes in the strap As shown in figures 7 and 8 three holes are positioned in the strap, one hole in the centre of the strap and one more at each end The strap is of a length at least as long as the circumference of the mouth of the wind sock tube and is placed around the mouth as shown in figures 11 , 12 and 13

As shown in figure 11 the aeπal is threaded through the central hole in the strap and also through the holes at each end of the strap which superimpose. Alternatively, as shown in Figure 12, the aerial is only threaded through the holes at each end of the strap In this case it is possible to use a strap which has no central hole and, if the strap is held onto the tube using a channel as shown in figure 11 then the channel only needs one cut out region 3 (see figure 1)

In a preferred embodiment the channel is formed by folding back the material at the mouth of the tube 2 to provide a channel 5 The material can be attached to the rest of the tube by any conventional means, for example by stitching, heat sealing or gluing

At least one and preferably two holes or slots 3 and 4 are provided in the channel in order that the strap can be inserted into the channel and that the holes in the strap are exposed The holes or slots 3 and 4 are diametrically opposed about the mouth of the tube as shown in figures 1 and 2 The holes or slots 3 and 4 may be rectangular or square cut outs as shown in figure 1 or alternatively may simply be an angled or curved edge Figure 29 shows an alternative type of hole 3, 4 which enable a continuous rim at the mouth of the display device tube to be retained In a particularly preferred embodiment the reinforcement takes the form of an adhesive stπp 32 formed from any suitable plastics material Such a strip is shown in Figures 36 and 37, Figure 37 showing typical dimensions The strips incorporate strategically placed holes 30 which allow for either aerial/pole mounting or for a 3 point mounting using the tπ-mounting struts illustrated tn Figures 38, 39 or

40 (see below)

The holes 30 may incorporate radial slits 31 to facilitate insertion of an aerial tip which is otherwise broader in diameter than the hole itself The strip 32 may contain adhesive on one side suitable for adhesion onto the tube material Any suitable adhesive may be used as suggested by the materials specialist

It is also possible to provide any of these different kinds of collar at the tail end of the tube to increase the flying characteristics of the display device

In alternative embodiments straps such as those shown in figures 20, 21 , 22 can be used As already mentioned by, using several different types of fixing a wide variety of fixing locations are possible For example, windows and bicycle handlebars Several of these different types of fixing are illustrated in figures 14 to 18 and Figures 30 to 32

Figure 26 shows an alternative attachment means which includes a stud for use together with a retaining strip A pair of studs and retaining strips can be used as shown in figure 26 or alternatively, only one stud and stπp This alternative attachment means can be used with any type of collar

Figure 19 shows another embodiment of the retaining strip As shown this is a small rubber band fitted with a sliding toggle It can be used as a retaining strip as follows • Slide the toggle to the centre to allow a loop either side of the toggle

• Put one loop over the end of the aerial

• Use the toggle to slide towards the aerial and tighten the loop against it

• Then the top aperture in the display device tube or in the retaining strap is placed over the top of the aerial and on top of the first loop

• The second loop of the elastic band is taken and fastened over the top of the display device tube or retaining strap and also over the display device collar if necessary onto the top of the aerial Twists can be made in the band in order to reduce any slack if necessary Figure 28 shows use of a swivel with the display device Two alternative types swivel are shown in this figure In order to fix the swivel to an aerial the following steps are followed

• Pass one end of the plastic strap through the hole in one end of the swivel

• Offer the plastic strap to the aerial, encircle the aerial, passing the tapered end of the plastic strap through its plastic fastener and drawing tight, thus affixing the swivel to the aerial with the plastic strap

• The other end of the swivel is then attached to the tie strings of the windsock

The shape of the tube is important for proper and efficient operation As well as the conical shape described above and novelty shapes described below other shapes are possible In order that the tube can remain inflated at relatively low speeds the diameter at the mouth region should be greater than the diameter at the tail region

The word "diameter" would tend to suggest a substantially circular cross- section However, this is not necessarily the case and square, rectangular and elliptical cross-sections are all acceptable What is preferred, however, is that there should be a restriction in air flow along the tube between the mouth and the tail end and preferably near the tail end In principle, any form of restriction will suffice from a taper to the overall shape to an internal restnction of some sort

A preferred profile for a tapered shape is shown in Figures 33, 34 and 35 These illustrate flattened profiles of various tubes, some with typical dimensions given Referring to Figure 33, this illustrates a tube 40 with a mouth 41 , a tail end 42 and upper and lower edges 43 and 44 respectively The plane of the mouth region 41 is angled at approximately 10° with respect to the perpendicular 45 struck from the upper edge 43 This arrangement encourages the display device to extend out substantially horizontally from the first fixing point even when the vehicle is moving at speed More specifically, it allows for any rearwards flexing that might take place in the pole, post, aerial or other fixing that the display device may be fixed to

The display device can also be made from material which has a finish such as a fluorescent or luminous finish Reflective materials or reflective coatings and

Display device adaptations include - An illuminated version of the display device is possible This can be achieved for example by placing a light bulb inside the display device and providing power for this bulb from a small battery source or from the car/vehicle cigarette socket or other power source

An auditory version of the display device This can be achieved by inclusion of a whistle or howler or other such noise-making device into the display device For example, the noise making device can be driven by air-currents and can be added to the tail end of the display device tube Figures 30 to 32 show alternative posts or pseudo aerials for used with window/clamp bracket fittings and rubber suction fittings Figure 30 shows an alternative method of fixing the display device which is to thread the collar of the display device tube around the spiral end of a pseudo aerial that is formed with a spiral end as shown This holds the mouth of the display device tube open and no strap is needed

The stop 21 on the mounting shaft 20 in Figure 32 is important because it provides a barrier to the bottom of the tube mouth rising too far up the post when the vehicle travels at speed The three pronged connectors 50, 60, 70 shown in Figures 38, 39 and 40 act as fastening means to fasten a tube to an aerial top or its equivalent Referring to Figure 38, spaced holes are provided in the reinforced collar of the tube and the individual ends 51 , 52, 53 are threaded through separate holes The end regions catch and secure in much the same way that a modern price tag is secured to a garment with a plastic strip The aerial point or equivalent is then inserted through hole 54 to install the display device in place

Connectors working on a similar principle are shown in Figures 39 and 40 In certain circumstances, it is preferred to mount the display device on a windscreen or other window of a vehicle Mounting units suitable for this purpose are illustrated in Figures 41 , 42 and 43 Figure 41 illustrates a semi-circular block

80 with a self-adhesive base 81 and various mounting holes 82 - 85 set at different angles Adhesive which will stick firmly to glass is well-known Once mounted, a short post is fitted into one of the holes as a first attachment means and a display tube attached to it by any of the means described above Figures 42 and 43 show a hinged version of a smaller but similar device Further examples of display devices according to the invention are described below where the trade mark ADSOCK is used to refer to the display device.

1. INTRODUCTION

The Adsock has been developed for use with the motor vehicle aerial and pseudo aerials affixed to bicycles, motorcycles and vehicle handlebars, wing mirror stays and fixings, boat pushpits/puipits/stays and vehicle windows The Adsock, as the name suggests, will carry a promotional message, company logo and/or signifying colours of a product or service The main purpose is to attract the attention of passers by and form a novel way of communicating any message be it branding/supporting or informative

2. IDENTIFYING CHARACTERISTICS The identifying characteristics of the Adsock are -

2 1 The flight wind-catching ability (due to the unique fixing and of being located on any vehicle) giving it an instant recognition by being inflated using the vehicle's motion, rather than the natural element of the wind as a windsock The essential requirement is that the mouth and tail of the Adsock is held open with commencement of vehicular motion This is achieved with the addition of a collar at the mouth and/or the tail to increase the circular appearance of the mouth/tail aperture This can also be achieved by increasing the gauge of material used at either or both these points 2 2 The design and material of construction being polythene and/or polythene derivatives necessitates particular flanges, holes and dimensions (see

Figures 1 to 4)

2 3 The colour and individual message carrying facility - i e allowing printing and being highly visible (see Figures 5 and 6 - showing colour/message carrying ability) 2 4 The Adsock requires motion to inflate it, this necessitates a requirement for a versatile and unique fixing method to attach it to suitable positions/locations on vehicles/boats, to include -

2 4 1 Aeπal/pseudo aerial (vertical/angled, static and retractable) 2 4 2 Window (top of window fixing to facilitate horizontal or vertical flight)

2 4 3 Standard size tubular fixing - e g handlebar

2 4 4 Variable diameter tubular fixing - e g frames, stays and wing mirror fittings

2 4 5 Flat surface fixing - e g roof, decking, etc
