Abstract
Abstract A sign comprises a frame having a rectangular front wall and side walls peripherally joined to the front wall. The side walls extend rearwardly from the front wall to define a rearwardly opening cavity. An aperture is defined in the front wall and includes an interior peripheral edge. Ledge means are joined to the front wall around the interior peripheral edge, extending rearwardly and inwardly therefrom. Display panel means, having a shape congruent with the aperture and sized for reception within the aperture, are supported by the ledge means. The frame comprises a pair of side members, each including an elongated central section and a first end section and second end section extending perpendicularly from the central section. Means are provided for linearly attaching each first end section to the second end section of the other side member.

A sign comprising (a) a frame having a rectangular front wall and side walls peripherally joined to the front wall, the side walls extending rearwardly from the front wall to define a rearwardly opening cavity, (b) means defining an aperture in said front wall including an interior peripheral edge, (c) ledge means joined to said front wall around said interior peripheral edge and extending rearwardly and inwardly from said interior peripheral edge, and (d) display panel means having a shape congruent with said aperture defined in said front wall and sized for reception within said aperture and for support by said ledge means, (e) said frame comprising a pair of side members, each of said side members including an elongated central section, a first end section extending perpendicularly from one end of said central section and a second end section extending perpendicularly from the other end of said central section, said first and second end sections of each said side member being parallel to one another, and means for linearly attaching each first end section of each of said pair of side members to the second end section of the other said pair of side members comprising tab means extending longitudinally from at least one of said end sections of one of said pair of side members for frictional engagement with an end section of the other of said side members.
Claim 3
Dependent Claim
42 words
A sign as defined in claim 1 and including a first elongated partition member extending between said pair of side members to divide said aperture into a plurality of subapertures and including means for attaching said first partition member to said frame.
Claim 4
Dependent Claim
63 words
A sign as defined in claim 1 wherein said linear attaching means comprise a pair of elongated connector members and said connector members include longitudinally extending tab means, each of said connector members being colinearly aligned with said first end section of one of said pair of side members and said second end section of the other of said pair of side members.
Claim 5
Dependent Claim
