Definitions
- This invention relates to light boxes, and in particular to light boxes for advertisements to be displayed in public places, such as at bus shelters.
- Street advertisements on bill boards or the like are well known and attract significant revenue for the owner of the bill board.
- Other ways of providing advertising space have been sought and, as a result, free standing advertising displays are becoming more common.
- shelters, such as bus shelters often now incorporate advertising space.
- Advertising display devices have progressed significantly over the last few years and now often include a light source within the device for illuminating the advertisement from within.
- Such light boxes comprise a frame, at least one door for accessing an advertisement mounted within the light box and a light source within the light box for illuminating the advertisement or advertisements for viewing from the outside of the light box.
- Such prior art light boxes have, in general, been relatively simple in their design.
- the present invention aims to reduce the loss caused by vandalism by providing a light box which can be readily restored to its former glory without significant expense.
- the present invention provides a light box for a bus shelter or the like, the light box comprising a support frame, a display surface for an advertisement supported by the frame and a light source within the frame for illuminating the display surface, wherein cladding is applied to the support frame to define an exterior surface of the light box, the cladding being releasable from within the light box to enable the cladding to be replaced.
- the cladding By making the cladding removable, damage to the exterior of the light box can be quickly repaired. Further, by designing the cladding to be released from the light box from within the light box, the cladding is unlikely to be removed by vandalism of the exterior of the light box.
- the display surface is formed on a diffuser behind a door of the light box.
- the door includes a clear plastics panel, made of polycarbonate or any other appropriate material, through which the advertisement positioned behind the door within the light box can be viewed.
- the door is preferably hinged to the support frame to facilitate access into the light box.
- a locking mechanism is preferably provided for retaining the door in a closed position. As a result, vandals cannot obtain access to the interior of the light box.
- the diffuser preferably carries clips for receiving an advertisement to be held adjacent the display surface. More preferably, the clips are ball clips mounted on the support frame at the top of the light box, in use, such that the advertisement hangs from the clips, in use.
- a diffuser is preferably positioned between the light source and the display surface, the diffuser being suspended from the support frame.
- the diffuser is manufactured from fibreglass.
- the light source may be one or more fluorescent tube suspended from the support frame.
- Two display surfaces may be provided, illuminated by a single light source.
- one display surface faces in one direction and the other display surface faces in the opposite direction.
- the cladding is preferably made of metal, although any other suitably strong material could alternatively be used.
- the cladding is, however, most preferably made of aluminium or steel.
- the cladding preferably clips onto the support frame with a snap fit.
- removal of the cladding from the exterior of the light box is extremely difficult.
- a sharp tap against the cladding may be sufficient to dislodge the cladding prior to the remainder of the cladding being peeled off the support frame.
- the support frame includes at least one aperture through which a rod can be poked to release the cladding from the support frame.
- a weather seal is preferably provided around the or each door to prevent the ingress of rain water or other weather.
- a base unit for carrying the light box.
- the base unit preferably includes some form of reinforcement, such as steel rods, which engage the support frame of the light box.
- a shelter incorporating at least one light box as herein defined.
- a display device comprises a light box 1 according to the present invention supported by a base 3 for anchoring the display unit to the ground.
- the light box 1 comprises a generally rectangular support frame 5 formed from lengths of a profiled extrusion. The shape of the extrusion profile can be seen in Figures 3, 4 and 6.
- the support frame 5 carries a pair of doors 7 hingedly connected to the support frame 5 as shown in Figure 3. In this regard, the doors 7 are hinged at their tops to the support frame 5 to enable access to be obtained to the interior of the light box 1 for mounting of an advertisement or the like in the light box 1.
- Each door 7 comprises a metal frame 9 defining an opening filled by a window 11 made of plastics material, such as polycarbonate.
- a locking mechanism 12 is provided to lock securely the door to the support frame 5 to prevent unwanted access to the interior of the light box 1.
- Ball type clips 13 are mounted towards the top of the light box 1 to receive posters or other advertisements to be displayed by the light box 1. By positioning the clips 13 towards the top of the light box 1, it is a simple matter for a door 7 to be opened and for a poster or other advertisement to be received by the clips 13 such that the poster hangs neatly behind the window 11 of the door 7 when the door has once again been closed and locked. The advertisement can then be viewed through the window 11 by persons passing the display unit.
- a light source (not shown), such as one or more fluorescent tubes, is positioned within the light box 1 between the two doors 7.
- the extrusion used for the support frame 5 includes two C-shaped sections 17 for receiving correspondingly shaped portions of two diffusers 15 as shown in Figure 3. Positioning of each diffuser 15 can, therefore, be achieved simply by sliding the diffuser 15 along the C-shaped section 17.
- a neoprene seal 19 is positioned between the support frame 5 and each door 7 to ensure that the inside of the light box 1 remains watertight against rain or other weather conditions.
- this comprises a reinforced frame 21 extending from feet 23 upwards into the support frame 5 of the light box 1.
- the light box 1 is provided with significant rigidity and is held firmly in position wherever the feet 23 of the base 3 are entered into the ground.
- the base 3 includes front and rear walls 25 which bow outwardly to produce an attractive appearance.
- cladding 27 is provided which defines an essentially smooth curved exterior surface.
- the cladding 27, which is formed by extrusion, has a section which mates with the profile of the support frame 5 by means of a snap fit. More particularly, the cladding 27 includes two legs 29 extending inwardly towards the support frame 5.
- Each leg 29 includes a stop 31 and a barb 33 for engaging an upstand 35 incorporating a small step 37 formed as part of the profile of the support frame 5.
- the legs 29 are slightly resilient, due to the nature of the aluminium from which the cladding 27 is manufactured, to enable the mounting of the cladding 27 with a snap fit.
- edges 38 of the cladding 27 are shaped with three fingers for abutment against flange 39 of the support frame 5. As a result, a good seal is formed at the juncture between the edges 38 and the support frame 5, thereby preventing a vandal from prizing the cladding 27 from the support frame 5.
- the sides of the light box 1 themselves also incorporate the same cladding 27 attached to the support frame 5 in like manner.
- a substantially flat piece of cladding 41 is used to seal the top of the support frame 5, as shown in Figure 3.
- the flat cladding 41 carries threaded studs 43 which pass through holes in a sheet 45 attached to the support frame 5.
- Nuts 47 are applied to the threaded studs 43 to retain the flat cladding 41 in position.
- Grommets 49 fill holes in the flat cladding 41 through which access can be obtained to the hinges of the doors 7, in the event that the doors 7 need to be removed.
- a light box according to the present invention is vandalised with a heavy object or spray paint, for example, it is a relatively simple matter to remove the cladding 27,41 from the light box 1.
- New cladding can then be applied to the display unit to improve the appearance of the display unit without incurring the significant cost of completely replacing the display unit or the component parts thereof.
- the cladding 27 is to be removed, it is simply necessary to give the cladding 27 a sharp tap from within the light box 1 to separate the legs 29 of the cladding 27 from the upstands 35 of the support frame 5. This can be achieved by passing a rod through an aperture in the support frame 5. Once the cladding 27 has been forced away from the support frame 5 in at least one position, the remainder of the cladding 27 can be "peeled" off the support frame 5.
- the display unit is designed to stand below a bus shelter, a part 55 of which is shown in Figure 7. More particularly, the bus shelter 55 includes a support pole 57, a glass or plastics panel 59 and a light box 1 according to the present invention.
- One end of the light box 1 incorporates a first style of cladding 51 which is designed to provide an appearance similar to that of the hexagonal exterior of the support pole 57.
- the cladding 51 is held on the support frame 5 by means of legs 29 incorporating a stop 31 and a barb 33.
- two separate pieces of cladding 53 are attached to the support frame 5 by means of screws 61 passing through the support frame 5 and engaging recesses in the cladding 53.
- the exterior of the cladding 53 is shaped to match the support pole 57 used in the bus shelter 55. However, this time an opening 63 is provided for receiving the support pole 57.
- any other suitable style if cladding could, of course, be used with the light box without departing from the scope of the present invention.
- the style of the cladding will simply depend upon the application in which it is to be used.
