Abstract

Abstract An illuminated display consists in a number of light box modules (11) each having a casing (12,13,14,15,16) and a light source within the casing for illuminating a transparency (23). Each module (11) is adapted for mounting to a skeletal support frame (7) in contiguous relationship with another. Preferably the module casing has sidewalls which on at least 3 sides include an inward step (14) adapted to engage members (7) of the frame.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 312 words
An illuminated display comprising a skeletal support frame an a plurality of light box modules, the skeletal support frame forming a plurality of contiguous, rectangular openings, each opening being of a predetermined size to receive one light box module, the front of the support frame defining an outside vertical surface, each module including a casing, a light source within the casing and means for mounting a transparency in front of the light source, each casing have a first rectangular portion of a larger size than the rectangular opening in the skeletal frame which receives the casing, and a second rectangular portion of smaller size than the opening, the first and second rectangular portions of the casing being contiguous and having a vertical step between them, each casing being removably inserted in an opening in the frame with the step abutting the outside vertical surface of the frame, the first rectangular portion projecting outwardly beyond the vertical surface of the frame and the second portion of the casing fitting within the rectangular opening, releasable means for retaining the module within the frame, the means for mounting the transparency in the module being a keeper flange supported by the projecting first rectangular portion of the casing, the top portion of the keeper flange being open to receive the transparency, the top of the said first rectangular portion of the casing extending outwardly from the step a greater distance that the bottom portion thereby to form an angle between the keeper flange and the step, whereby the top opening of the keeper flange of a first lower module is forward of the bottom edge of the keeper flange of a second upper module which is located contiguous with the top edge of the first module so that a transparency may be inserted and removed from the first module without removing either module from the frame.
Claim 2
Dependent Claim 312 words
An illuminated display comprising a skeletal support frame an a plurality of light box modules, the skeletal support frame forming a plurality of contiguous, rectangular openings, each opening being of a predetermined size to receive one light box module, the front of the support frame defining an outside vertical surface, each module including a casing, a light source within the casing and means for mounting a transparency in front of the light source, each casing have a first rectangular portion of a larger size than the rectangular opening in the skeletal frame which receives the casing, and a second rectangular portion of smaller size than the opening, the first and second rectangular portions of the casing being contiguous and having a vertical step between them, each casing being removably inserted in an opening in the frame with the step abutting the outside vertical surface of the frame, the first rectangular portion projecting outwardly beyond the vertical surface of the frame and the second portion of the casing fitting within the rectangular opening, releasable means for retaining the module within the frame, the means for mounting the transparency in the module being a keeper flange supported by the projecting first rectangular portion of the casing, the top portion of the keeper flange being open to receive the transparency, the top of the said first rectangular portion of the casing extending outwardly from the step a greater distance that the bottom portion thereby to form an angle between the keeper flange and the step, whereby the top opening of the keeper flange of a first lower module is forward of the bottom edge of the keeper flange of a second upper module which is located contiguous with the top edge of the first module so that a transparency may be inserted and removed from the first module without removing either module from the frame.
Claim 3
Dependent Claim 37 words
An illuminated display according to claim 1 wherein the casing of each module is positioned in the frame such that a transparency displayed by one module is substantially contiguous with a transparency displayed by an adjacent module.
Claim 4
Dependent Claim 56 words
An illuminated display according to claim 1 wherein one module is mounted in the frame member in contiguous relationship with a first edge of another like module and a third like module is mounted in contiguous relationship with a second edge of the said other module, which second edge is perpendicular to the said first edge.
Claim 5
Dependent Claim 30 words
An illuminated display according to claim 1 wherein two modules are mounted in the frame member adjacent each other and wherein the transparencies lie in planes normal to each other.
Claim 6
Dependent Claim 25 words
An illuminated display according to claim 1 wherein the transparency mounting means is of a size sufficient to receive a transparency of 30 cm×30 cm.
Claim 7
Dependent Claim 40 words
An illuminated display according to claim 1 wherein a plurality of modules are electrically connected with a master module, the master module including electronic control means for switching the light of each module on in a predetermined sequence of combinations.
Claim 8
Dependent Claim 27 words
An illuminated display according to claim 1 wherein said light box modules are molded from a plastic material and have inwardly tapering sidewalls located within the frame.
Claim 9
Dependent Claim 31 words
An illuminated display according to claim 1 wherein the releasable means is at least one spring clip engagable between the casing and the portion of the frame forming the rectangular opening.
