TECHNICAL FIELD
This invention relates to illuminated display devices which include one or more housings, interior lights, and translucent panels for presentation of a backlit advertisement or promotional item, particularly for outdoor environments.
BACKGROUND ART
Illuminated outdoor signs and display devices are commonly in use for many purposes today, particularly for presenting advertising and promotional materials relative to various businesses. Fast-food restaurants in particular use illuminated signs on their premises adjacent pathways leading to the restaurant or along their vehicle drive-through service lanes. The devices are used to display various menu items and/or to provide information and prices for consumers. In addition, the marketing of “specials” are often promoted by these devices.
Restaurants and other businesses utilize a number of various types of signs, both lighted and unlighted, and both indoors and outdoors, for promotion of their goods and services. These signs are often lighted for nighttime viewing, either in the front by flood lights or overhead lighting, or from the back through transparent panels. These types of signs have various concerns and problems relative to providing devices which are economical, aesthetic and durable. When used outdoors, the displays must also be able to withstand environmental conditions, such as wind, rain, snow, sun, freezing temperatures and elevated temperatures, and still maintain their integrity and usefulness for their intended purposes.
Outdoor sign devices which have enclosed housings with transparent members covering and protecting the promotional materials, often have condensation and moisture problems. Moisture which enters the device or is created by condensation is often difficult to remove and frequently adversely affects the aesthetics and visibility of the displays. Lighted signs, particularly those that are internally backlit, often have an increased problem from moisture and condensation due to the heat generated by the lights. The lights also can accentuate any distortions or warping of the advertising materials, creating additional concerns.
It is also important with outdoor signs chat security procedures of some type be taken so that the messages and pricing materials on the signs cannot be tampered with or vandalized. At the same time, it is also necessary to allow frequent and easy access to the displays by authorized personnel in order to change the promotional items or add additional current items.
Further, it is of interest to businesses to include additional advertising and promotional posters and items on the device housings to advertise and promote “specials” or other current matters.
It is an object of the present invention to provide improved outdoor illuminated sign devices, particularly for holding and displaying advertising and promotional materials. It is another object of the present invention to provide illuminated sign devices which create airflows inside the structure to minimize or prevent moisture and condensation problems, and to minimize heat build-up.
It is an additional object of the present invention to provide illuminated devices which have transparent doors on the front for protecting advertising and promotional materials from environmental elements and for preventing unauthorized or inadvertent access to the materials. At the same time, it is an object of the present invention to provide illuminated devices which are readily accessible by authorized personnel to change, remove or add to the displayed materials.
It is a still further object of the invention to provide illuminated devices which have one or more areas or portions for presentation of price and menu items behind a transparent door, and other areas or portions for direct display of posters and other displays.
Other objects of the present invention include providing a more stable illuminated sign system, providing a modular sign system which allows flexibility in the size and display of the advertising portions, and providing unique backlit display modules for displaying prices and menu items inside illuminated sign devices.
These and other objects, features, benefits and advantages of the present invention will become apparent when the following description of the invention is viewed in accordance with the attached drawings and appended claims.
SUMMARY OF THE INVENTION
The present invention provides illuminated display devices which are improvements over known illuminated display devices. An enclosed housing containing a plurality of lights, particularly fluorescent lights, has a first area or portion with a transparent cover for placement of the pricing, advertising and promotional materials, and a second display area or portion for additional posters and displays. The first area is typically divided into a number of sections, each section displaying a separate advertising or promotional material or a menu board with prices thereon. The pricing members preferably have the ability to be changed quickly and easily. The materials in the second area are held in place by clamping members positioned around one or more edges of the display materials and by extrusions with display channels.
A transparent door is provided on the front of the device to protect the advertising and promotional materials in the first area from the elements and also from vandalism. A frame is provided around the perimeter of the door made from extrusion members. The door is hinged to the housing along its upper edge. A latching mechanism is utilized to secure the door to the housing when it is closed. A latching/unlatching mechanism, preferably hidden from view of customers, allows the door to be opened for change of the messages on the surface of the menu and display board. A pair of gas-assisted springs positioned between the door and the housing permit the door to be opened and closed in an efficient manner.
A space or gap can be provided around the perimeter of the door of the display device to allow air to flow between the door and the menu and display materials. Alternatively, the door can be sealed against the display device and one or more vents provided in the back of the device in order to allow circulation of air and venting of any hot air build up inside the device. The menu and display portion of the housing allows quick and easy change of the advertising and menu sections. A plurality of lights, such as vertical or horizontal fluorescent lights positioned in the housing provide light through the advertising and menu displays in order to make them visible to the public. In this regard, the advertising and promotional materials, as well as the members forming the price and menu signage, are at least partially transparent or translucent in order to allow the light from the fluorescent lamps to pass through them.
The two outer sides of the housing can be provided with rounded extrusions. These extrusions are adapted to blend with the door member when the door member is closed in order to provide a smooth appearance without any sharp angles or corners.
Alternatively, the sign device can have a plurality of modular members which are adapted to be secured to the sides or top of the display device to increase the advertising and promotional size and value of the device.

BEST MODE(S) FOR CARRYING OUT THE INVENTION
One preferred embodiment of the present invention is depicted and illustrated in FIGS. 1-18 of the drawings. The illuminated lightbox or display device is referred generally by the reference numeral 20.
FIGS. 1-3 depict the size, shape and configuration of the illuminated display device 20. The present invention preferably has use as an outdoor illuminated sign box device at drive-through lanes at fast-food restaurants. It is understood, however, that the illuminated device in accordance with the present invention can be used for other purposes and in other environments, such as indoors.
As illustrated, the device 20 includes a housing 22 which has a front surface 24, a rear surface 26, an upper surface 28, a lower surface 30 and two side surfaces 32 and 34. The housing is attached to a base 40.
The base 40 is comprised of a series of aluminum panel members formed in the configuration shown and which surround a pair of steel pedestals 42 and 44. The pedestals 42,44 are attached to base plates 43 and 45 which are secured in any conventional manner, such as by bolts or other fasteners, to a concrete base footing or the like (not shown). The pedestals 42,44 also have plates 46,47 at their upper ends which are attached to a torsional tubular member 48 in the lower portion of the housing 22. The tubular member 48 is attached to the lower surface or panel member 30 of the housing and in turn connected to the plates 46,47 by bolts or other conventional fastening means.
The two side surfaces or members 32,34 of the housing 22 also have a shape and configuration which matches that of the base cabinet 40. In this regard, the side members 32,34 are made from aluminum extrusions formed in a rounded or bullnosed shape. Not only does the rounded shape of the sides provide a pleasing and aesthetic configuration for the device 20, but it also provides for a smooth transition from the side surfaces to the front and rear members 24, 26 without sharp angles or corners.
The rear surface or member 26 of the housing is a panel of aluminum sheet material. It is connected to the extruded side members 32, 34 by rivets or other conventional fasteners 27 (see FIG. 5).
Inside the housing and adjacent the rear panel are positioned a plurality of horizontally disposed fluorescent lamps 50. In the embodiment illustrated in the drawings, six lamps 50 are provided, although it is understood that any number can be utilized depending on the size and configuration of the housing and the desired illumination. The fluorescent lamps can be of any conventional type and preferably are six feet long. A six lamp ballast member 52, which can be of any conventional type but preferably made by Magnetec, is provided to operate the lamps 50. The lamps are positioned in conventional fixture members 54 positioned in interior side members 56 as shown in FIG. 18. The fixtures are-connected to the ballast member by appropriate wiring (not shown) and the ballast in turn is connected by appropriate wiring to a power source (again not shown), both as conventionally known in the art.
The front surface 24 of the housing 22 is open in order to allow illumination from the lamps 50 to project outwardly for viewing by the passing public. A plurality of menu and graphic modules, or advertising and promotional modules are positioned covering the front surface. The modules and display are illuminated from the rear so that the graphic materials, displays and prices on the modules will be visible to the viewing public.
The front surface 24 can be utilized to provide one large graphic message to the passing public, or can be divided into a number of sections or areas. The latter is preferable and six sections are shown in the FIGS. 1-2 of the drawings. As shown, the areas 54,55,56,57,58 and 59 comprise pictures or photographs of various food items, various menu items, various pricing numbers relative to the menu items, and other conventional advertising and promotional items. Preferably, the sections or areas 54-59 of the present invention are covered by frames or modules which can be prepared off site and then installed or assembled in place in the housing for display. This also allows the modular units to be moved around and positioned at any location on the front surface as desired by the business establishment.
One of the embodiments of menu/graphic frame modules 70 for use with the present invention are shown in FIGS. 12-15; The manner in which the modules 70 are positioned in the display 20 is shown in FIGS. 16-18. A horizontal aluminum extrusion member 80 divides the front surface into two equal areas. Divider member 80 has a pair of flanges 82 and 84 which hold the outer edges of the menu/graphic frame modules 70 in place.
Vertical divider member 90 is used to divide the front area into a series of separate sections, preferably four vertical divider members 90 are utilized, each being an aluminum extrusion in the configuration shown in FIG. 16. Channels 92 and 94 on the vertical divider member hold the edges of the menu/graphic frame modules 70 in position. Also, as shown in FIG. 18, vertical extrusion members 98 are provided along the two outer vertical edges of the front surface area 24. These are adapted to hold the edges of the menu/graphic frame modules 70 in place.
The menu/graphic frame modules 70 shown in FIGS. 12-15 have an outer frame 210 comprised of four frame sections 211-214. The frame sections are mitered at 45° at each end and held together by corner key members 216 to form the frame 210. The frame sections preferably are made from aluminum extruded in the cross-sectional shape shown in the drawings, and the corner key can be made of metal with locking tangs 218 used to hold the key in place in channels 220 in the frame sections. It is understood that the frame sections and key members could also be made of other configurations and from other materials, such as suitable plastic materials, although it is believed that metal members work better in accordance with the present invention. The corner key members could also be attached to the frame sections by screws or other fasteners.
The modules 70 have a plurality of divider members 224 positioned horizontally at predetermined positions on the frame 210. The divider members 224 are elongated aluminum extrusions having a cross-sectional shape shown in FIGS. 13A and 14. The divider members have a U-shaped opening 226 formed by two leg members 228 and 230. The free ends of the leg members 228,230 have locking ridges 232 and 234, respectively. A pair of channels 236 and 238 are present in the other end 240 of the divider members. Although the divider members preferably are made of an extruded aluminum material, other materials of suitable durability could also be utilized.
A plurality of retainer members 250 are secured on the inner edge or surface of two opposed frame sections 211 and 213. The retainer members are preferably made from a plastic material, such as acetal, but any other material could be utilized which can perform the same function and purpose. The retainer members 250 have an angled or sloped end 252 and a pair of grooves 254,256 at the other end. The grooves are adapted to mate with the locking ridges 232,234 of the divider members when the divider members are installed on the module.
The retainer members also have nubs or projections 260 which are adapted to mate with recessor or holes 262 in the frame sections 211, 213. Fasteners 262, such a pop rivets, positioned in openings 264 in the retainer members, secure each of the retainer members to the frame sections. The retainer members also have slits or channels 266 which fit over flanges 268 on the frame sections.
The divider members 224 are used to divide the open face of the module into a plurality of horizontal areas 270 for placement of various menu strips 275 and price modules 280. The menu strips 275 are elongated thin strips of plastic or metal and fit within channels 236,238 between adjacent divider members. The strips 275 can be one space 270 in width, or can span several spaces and divider members. Of course, if the strip 275 is positioned to span several areas, it may not be necessary to provide divider strips beneath the strips, unless they are needed for support. In this regard, strip 275 in FIG. 13A is positioned between adjacent divider members, while strip 275A is positioned spanning over one divider member which has been removed.
The frame sections 212 and 214 are provided with channels 219 and 221 in order to hold an edge of a strip positioned between a divider member and a frame section. In this regard, it is also possible to position a single graphic or display panel covering the entire open front surface of the module 70, the panel being positioned in channel 219 in frame section 212 and in the corresponding channel 221 in frame section 214 (see FIG. 13A). Frame sections 211 and 213 also have strip channels in them in order to hold the ends of the strips.
It is also possible to position one or more price modules 280 in between adjacent divider members 224. One embodiment of price modules which can be used is shown in FIG. 15 and is available from Wolfe Merchandising, Toronto, Ontario, Canada. The price modules 280 comprise plastic housings 282 with a series of adjustable number strips 284 so that the price shown to the public can be changed as desired by the business. Of course, other conventional pricing strips or devices for displaying prices of the menu items to the public could be utilized. Spring locking tabs 286 on the sides of the price modules 280 hold the modules in place between adjacent divider members.
Another pricing strip which can be used with the present invention is shown in FIG. 30. This module 300, which is made of plastic or equivalent materials, has a flat body member 302 with a plurality of windows or openings 304 (four being shown for illustration purposes). Overlapping light blocking flange members 303 and 305 are provided on the two opposite ends of the body member 302. Small individual number (or blank) members 306 are adapted to be positioned in front of each of the windows 304 and can be easily removed for replacement. Rail members 308 are positioned on the sides of each of the windows and used to hold the number members 306 in place. The actual number, letter or other graphic symbol 307 on the members 306 are made from a clear or translucent material so that they will be visible when the modules 300 are backlit. One or more price modules 300 can be positioned in each of the spaces 270 between adjacent divider members. The body member 302 is sufficiently thin in order to fit in channels 236 and 238 in the divider members.
The modules 70 could be positioned in all or any number of the areas 54-59 of the device 20. Typically, a restaurant will have a few modules which display menu items, with assorted prices, while other modules will have graphic displays of some of the food items themselves. Also, as indicated, the present invention can be used either indoors or outdoors and thus the modules 70 have application in both environments.
Another preferred embodiment of a menu/graphic module is shown in FIGS. 26-29 and indicated generally by reference numeral 320. A planar elevational view of the module 320 would be the same as that illustrated by module 70 in FIG. 12. FIGS. 26 and 27 are cross-sectional views of module 320 taken along the same lines and in the same manner as FIGS. 13A and 13B with respect to FIG. 12. FIG. 28 depicts a preferred retainer member utilized with module 320 and is positioned in a similar manner and has the same function as retainer members 250 with respect to module 70. FIG. 29 is a perspective view depicting the insertion channels 358 for menu strips between adjacent divider members and highlights the angled surface 364 (ramp member) used to aid in the insertion and placement of such menu strips.
Module 320 has four frame members forming an integral rectangular modular frame 322. Three of the frame members 324, 326 and 328 are shown in FIG. 26. The fourth frame member 330 is shown in FIG. 27. Frame members 324, 326, 328 and 330 correspond to frame members 211-214 in FIG. 12 and are held together in the same manner.
Side frame members 326 and 330 have a plurality of retainer members 332 which are spaced uniformly along the inside edges thereof. The members 332 are preferably made of DELRIN®, acetal, or a similar engineering grade plastic material. The retainer members have a sloped end 334 and a pair of grooves 336 and 337. A protruding locking member 338 having a pair of locking tangs 339 and 340 allows the retainer members 332 to be securely attached to the frame members. Slot 342 positioned between the locking tangs allows the tangs to be squeezed together sufficiently to allow the protruding member 338 to be inserted through openings 344 in the frame members. End surface 346 abuts the frame member and holds the retainer members firmly in position. Channel 348 is adapted to mate with flange 350 on the frame members and assist in holding retainer members in fixed position and orientation.
A plurality of elongated divider members 352 are positioned horizontally in the module 320 and secured to pairs of retainer members 332. Locking ridges 353 and 354 on leg members 355 and 356, respectively, are adapted to mate with grooves 336 and 337 on the retainer members 332 and thereby releasably retain the divider members in place. A pair of channels 357 and 358 are provided in each of the divider members and used to hold and display menu strips 360 or other display materials 362, as shown in FIG. 26. In contrast with channels 236,238 in the divider member 224 discussed above with reference to FIGS. 12-15, the channels 357 and 358 are overlapped and staggered in the vertical direction on each of the divider members 352. In this manner, a larger number of menu strips or a greater area of display materials can be positioned in each of the modules 320.
Slots or channels 219′ and 221′ are provided in the two horizontally disposed frame members 328 and 324, respectively, and are utilized to retain edges of menu strips or display materials in the same manner as channels 219 and 221 discussed above with reference to FIG. 13A. Channel or slot 363 is provided along frame member 326 for essentially the same purpose, namely to hold and retain the ends of menu strips and display materials positioned in the module 320 between adjacent divider members. Angled surface or ramp member 364 is provided in frame member 330 in order to assist in introducing a menu strip or display member between pairs of adjacent channels 357 and 358 (see FIGS. 27 and 29). In addition, angled surface or ramp member 366 is provided in frame member 326 adjacent channel 363 in order to assist in positioning the ends of the menu strips and display members in the channel 363 (see FIG. 27).
Although the invention has been described with reference to use of a plurality of individual retainer members (members 332 in FIG. 26 and members 250 in FIG. 13A), it is also possible in accordance with the present invention to utilize other mechanisms for releasably retaining the elongated divider members in the modular frame device. For example, as shown in FIG. 29A, an elongated formed (cast, molded, extruded, cut) strip member 380 could be provided with a plurality of retainer projections 382 thereon, and the formed strip member could be secured to the two inside vertical sides of the modular frame device. Grooves 336′ and 337′ would act to hold the horizontal divider members 352 in place. As another alternative, a plurality of retainer projections or members could be formed integrally as part of one or both of the vertical side frame members. Combinations of these various alternatives could also be utilized (e.g. with individual retainer members on one frame member and formed retainer projections on the opposed frame member).
A door member 100 is attached to the front of the housing 22 (see FIGS. 1-4 and 18). The door member 100 is pivoted about hinge mechanism 102 and also attached to the housing by a pair of gas-assisted spring members 104. The spring members 104 allow the door member 100 to rise slowly once it is unlatched. The spring members 104 also hold the door member in place when it is open and prevent it from being raised too high. Spring members could also be provided which simply pop the door open slightly (a few inches) and then assist persons manually opening the door to its maximum extent. With these spring members, opening of the door to its full extent is not automatic.
A frame 106 consisting of a plurality of frame extrusion members 108 is provided around the edges of the door member 100. A piece of tempered glass 110 held in the frame members with vinyl glazing 112 is positioned inside the frame 106 to form the door member 100. The upper edge of the door member 100 that forms part of the hinge mechanism 102 has a separate extrusion 112, as shown in FIGS. 7-9. The hinge member 112 has a rounded pintle portion 114 which mates with a circular socket 116 on mating hinge extrusion member 118 which is connected to the upper panel member 120. In order to prevent the door from being improperly removed, hinge members 112 and 118 are formed in the configuration shown so that they can only be assembled and disassembled in the manner shown in FIG. 7. The installed hinge mechanism 102 is shown in FIGS. 8 and 9 with the door being in an open position in FIG. 8 and in a closed position in FIG. 9. Once the door 100 is assembled on the housing as shown in FIG. 7, and the spring members 104 are connected to the door and secured to the housing, the door member 100 cannot be disassembled from the housing.
In this regard, the curved portion of the pintle member 114 is dimensioned such that it will fit within the socket 116 in the direction shown by the arrow 122 in FIG. 7, but cannot be disassembled when the door member 100 is in either of the positions shown in FIG. 8 or 9 or anywhere between those two positions. The socket 116 is curved more than 180° in order to retain the pintle member 114 in it. The pintle member 114 also has a curved member of more than 180°, but also has an open portion 115 which allows assembly with the socket member as shown in FIG. 7.
Several hinge members 112 on the order of 6-8 inches in width are provided along the top edge of the door 100. Preferably about 2-4 hinge members 112 are needed for the display device. As indicated, the door extrusion members 108 are positioned along the four exterior front edges of the glass 110 forming the frame 106. The plurality of hinge extrusion members 112 are positioned along the upper edge of the door member. The hinge extrusion members are formed from an extruded aluminum material and are provided in the size and shape shown in the drawings, particularly FIGS. 7-9. The hinge extrusion members are secured to the door member along the upper edge in any conventional manner, such as welding, rivets, or other fasteners.
When the hinge extrusion members are secured to the door extrusion member along the upper edge of the door member, the door assembly can be rotated to its open and closed in order to provide access to the advertising and promotional materials and to prevent their exposure to environmental elements and vandalism.
FIGS. 22-24 illustrate the assembly and the open and closed positions of door member 400 in a perspective manner. Once the pintle member 414 on hinge member 412 is assembled together with socket member 416 on hinge member 418, as shown in FIG. 22, and the spring members are attached to the housing and door member, then the door member 400 cannot be removed or disassembled in any unauthorized manner. This prevents unauthorized entry into the housing and also provides a display device having a more aesthetic, smooth exterior surface without any visible or protruding hinges.
Also, in accordance with a preferred embodiment of the invention which is shown and disclosed with reference to FIGS. 19-21, the hinge member 412 extends across the entire width of the housing. A sealing member 420 can be used to seal the top outer visual edge of the door member 400 with hinge member 418, but is not preferred. The sealing member 420 can be of any conventional type and can be made of any conventional sealing material, such as rubber or another elastomer.
With the present invention, the door member can be more easily removed for service or change without having to unscrew or disconnect a hinge mechanism, as with conventional doors on conventional box-like products.
A latching mechanism 130 (as shown in FIGS. 3A, 10 and 11) is used to secure the door member 100 to the housing 22 when the door member is in its closed position. The latching mechanism includes a pair of C-shaped latch members 132 attached to the lower corners of the door 100. The members 132 have U-shaped openings 133 in them and a spring activated finger member 134 which only can be moved in one direction. The latch members 132 are secured to the opposite lower corners of the frame 106 on the door member 100.
The latch mechanism 130 also includes a pair of pin members 136 on the housing 22. The pin members 136 are positioned on the opposite inside corners of the housing and are positioned to mate with the U-shaped openings 133 in the latch members 132 when the door member 100 is in its closed position. The pin members 136 are positioned in a U-shaped brackets 138 and are spring biased by coil springs 140. The pin members 136 slide or move in the direction of the arrow 142 (FIG. 11).
The pin members 136 are attached to elongated rod members 144 and 146 which are activated by turn lock mechanism 148. The turn lock mechanism 148 has a socket 150 for an alien wrench or key 152. When the key 152 is inserted in the socket 150 and turned or rotated, this in turn rotates the turn lock mechanism 148 in the direction of the arrow 154 shown in FIG. 11. This in turn operates to move the rods 144,146 which in turn move the pin members 136 out of engagement with the latch member 132 on the door member 100 thereby allowing the door to open.
When the door is in a closed position, the glass member 110 and frame 106 are positioned flush with the front surface of the housing 22. In this position, the latch members 132 are held in place by the pin members 134 which are positioned in the U-shaped openings 133 of the latch members 132. When it is desired to release the latching mechanism and allow the door 100 to be opened, turn lock mechanism 148 is activated by key member 152 and the pin members 136 are released from engagement with the latch members 132. The assistance provided by the spring members 104 moves the door member 100 a short distance away from the front surface of the housing in order to allow the door to be manually opened to its full open position (as shown in FIG. 3).
In one preferred embodiment of the invention, an air space 140 is provided around at least the two side and bottom edges of the door frame 106 when the door is in the closed position. This is shown in FIG. 18. A similar air gap 142 can be provided along the upper edge of the door member 100, as shown in FIG. 9. Since hinge members 112 are on the order of 6 to 8 inches in width and only 2-4 of them are provided across the several foot width of the housing 22, the air gap 142 allows sufficient quantities of air to pass through it along the top edge of the door 100.
The air gaps 140,142 allow air to circulate behind the glass door member 100 and in front of the menu/graphic frame modules 70. This allows any buildup of heat to escape from the area 150 between the door member and the displays and also prevents a buildup of water vapor and condensation which may adversely affect the graphic materials. Any buildup of condensation or water vapor on the inside of the glass 110 could also blur or distort a clear view of the menu and graphic materials displayed in the illuminated lightbox device.
Another preferred lightbox device in accordance with the present invention is shown in FIGS. 19, 19A, 20 and 21, and indicated by the reference numeral 500.

The door member 400 is attached to the front member 505. The door is sealed by sealing members 510 to the front member along the two sides and lower edge of the door. The door is hinged to the top member 503 by the hinge mechanism shown in FIGS. 22-24.
In contrast to the fluorescent lamps positioned horizontally in the embodiment shown in FIGS. 1-4, the fluorescent lamps 512 positioned in housing 502 are positioned vertically. This is shown in FIGS. 19-21. In addition, the supporting framework 501 for the device 500 includes a pair of vertically upright steel support members 514 and 516, and a plurality of horizontal steel support members 518-523 welded to the vertical members. This is shown in FIGS. 19 and 19A. Steel plate members 524 are welded to the outer ends of the horizontal members to add stability and fastening surfaces for the outer surface members of the housing. The steel supporting framework, as shown in FIGS. 19-21, may provide a more stable display device 500 than the supporting framework for the display device 20 as described above.
The lower ends 514a and 516a of the framework 501 are attached or secured in any conventional manner to an appropriate concrete base or other equivalent member 530.
An alternate embodiment of the invention is shown in FIG. 19B. In this embodiment 570, a plurality of point light sources 572, such as halogen lamps, are provided in the housing 574 in order to backlight the menu modules and other display materials. Diffuser members 576 are positioned in between the point light sources and the backlit displays in order to spread out the illumination evenly on the display. The diffuser members preferably have a plurality of patterned openings or spaces, the openings being spaced to even out the light distribution. Illumination systems and light diffusers of this type are shown, for example, in co-owned U.S. Pat. No. 5,381,324, the disclosure of which is hereby incorporated by reference herein.
In accordance with the embodiment shown in FIGS. 19-21, the sides of the housing can have square edges, or can be provided with bullnose cover members 532, as shown in FIGS. 19 and 20. Also, the portions of support members 514 and 516 which extend below the bottom member 504 can be covered with a housing with square or rounded edges.
Fresh cooling air is circulated through the housing 502 through openings in the back member 506. One or more air vents 540 are provided in the back member adjacent the lower or bottom member 504 in order to allow fresh air to enter the housing. The air vents 540 are covered with cap members 542. Filter members 544 are positioned in the cap member to prevent dust and other impurities from entering the inside of the housing. One or more exit openings 546 are provided in the back member 506 in order to allow hot air to escape from the housing. The openings 546 are covered by cap members 548. Cap members 542 and 548 prevent unauthorized entry into the housing and also keep rain, snow, debris and other environmental elements from entering the housing.
Louvers could also be provided on the housing for air circulation in place of the cap members and openings. The rear panel of the housing could be provided with a plurality of slits and openings, and louvers could be formed around them. Conventional filter materials, such as foam members, could be secured inside the housing covering the openings.
A second area or portion 160 is provided on the housing 22 for display of additional advertising and promotional materials. The advertising and promotional materials are designated generally by the numbers 162 and 164 in FIG. 1. The materials are also shown in FIG. 5. Spring-type clamping members 166 are provided along the lower edges and two side edges of the area 160. The clamping members 166 are preferably of the type described and shown in U.S. Pat. No. 4,145,828 which is assigned to the same assignee as the present invention. The clamping members 166 comprise an external cover member 168 which has an elongated circular hinge formation 170 at one end and mates with a pintle formation 172 on the base member 174. Cover member 168 is adapted to rotate between an open position in which the advertising and promotional materials 162,164 can be inserted or changed in space 160, and a closed position in which the cover member 168 rests on the materials 162,164 and holds them in place along two of their edges. A plurality of leaf spring members 176 are used to bias the clamping cover members 168 in an over-center manner and allow the covers 168 to be snapped and held in their open and closed positions. This is shown in U.S. Pat. Nos. 4,145,828 and/or 3,310,901, the disclosures of which are incorporated by reference.
An extruded T-shaped divider member 190 is positioned on the panel member 180 and secured thereto by any conventional fastening means. The divider member 190 has a pair of channel members 192,194 which allow placement of the materials 162,164 and holds them in place.
The divider member 190 can be positioned at any convenient position along the panel member 180. As shown in FIGS. 1 and 2, the divider member is preferably positioned such that one large display member 162 can be utilized, together with one smaller display member 164.
To assure that the advertising and promotional materials 162,164 remain in place in the section 160 of the housing 22, a plurality of spring clips 200 are provided along the upper surface 28 of the housing. The spring clips are provided at certain locations along the upper surface 28 and are adapted to be positioned through openings 202 provided in the display materials 162,164. The spring clips are secured to the upper surface in any conventional manner, such as by rivets 204. The spring clips have a downwardly extending flange member 206 on the outer end which hooks over the promotional materials 162,164 to help hold them in place.
With use of the spring clips and the clamping members 166, the poster display materials 162,164 are placed on the housing 22 in the following manner. First, the cover members 168 of the clamping members 166 are all rotated to their open positions. The display materials 162,164 are then positioned in place against the panel members 180. In this regard, the edges of the materials 162,164 are positioned in the channels 192,194 of the divider member 190 and the spring clips 200 are inserted through the openings 202. Thereafter, the cover members 168 are snapped to their closed positions, as shown in FIG. 5, securely holding the display materials 162,164 in place.
Another mechanism for holding the display materials 162,164 in place on the housing is shown in FIG. 25. The mechanism 550 is a turn-lock device with a stationary base member 552 which protrudes slightly through opening 202 in the display materials and a rotating locking member 554 which can be rotated 90° relative to the base member. The locking member 554 is rotated to a first position in alignment with the base member 552 in order to remove and replace display materials on the housing. Once the display materials are situated in their desired positions, the locking member 554 is rotated 90° relative to the base member, thereby securely holding the display materials in position.
In another preferred form of the present invention, both portions of the lightbox are illustrated. In contrast to the embodiment shown above which has a non-illuminated second area or portion 160, the device 500 can have a second illuminated lightbox member 560′ positioned on the top member 503. The member 560′ can have one or more fluorescent lamps 562 positioned in it and provide illumination to backlight the display materials 162 and 164. The lightbox member 560′ can be a separate modular member which is fastened to the housing 502 by any appropriate or conventional means. Also, if a second illuminated lightbox member is provided, then the front of the lightbox comprises a transparent panel. Rotating locking members, such as 554, are not utilized. Instead, the display piece is preferably attached around all four sides or edges with biasing clamping frame members.
With the present invention, it is possible to provide an illuminated lightbox device which is versatile and adaptable to numerous forms and configurations. The device has a central or main illuminated lightbox which can have modular members attached to it to increase its size and advertising capacity.
