Abstract

Abstract The frame comprises separate frame members joined together to form a rectangular structure for receiving a display device such as a placard. A bracket having a pair of legs forming a right angle is provided at each corner of the frame to secure the frame members together. Each frame member has a pair of oppositely disposed, longitudinally extending grooves on the rear side which receive the legs of the brackets. A screw is provided on each leg of the brackets. Each screw has an enlarged head which clamps against a lip portion on the frame members to fasten the brackets to the frame. The upper frame member is utilized to mount the adjustable hanging clip. The adjustable hanging clip has upwardly and downwardly extending projections. The downwardly extending projection is received in the lower groove. The upwardly extending projection is depressible downwardly for insertion into the upper groove. A hanger structure is provided on the clip and is spaced rearwardly from the projections so that it will not have to extend above the frame. The positionment of the hanger member results in a lever action from the point of securement of the hanger structure to the frame resulting in the frame tending to rotate towards the support structure on which the hanger is secured. This prevents stress being applied to the depressible upwardly extending projection. The clip is slidable along the frame member to permit centering.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 149 words
A clip for hanging a frame comprising a base structure having a forward and rearward portion, downwardly projecting structure on the forward portion of the base structure for reception in a first groove of a frame member, first upwardly projecting structure on the base spaced rearwardly of the downwardly projecting structure, a flexible arm extending laterally from the fIrst upwardly projecting structure and terminating in a free end, second upwardly projecting structure on the arm spaced forwardly of the first upwardly projecting structure for reception in a second groove in a frame oppositely disposed from said first groove, whereby the clip may be mounted on a frame by inserting the downwardly projecting structure into the first groove and then depressing the arm and inserting the second upwardly projecting structure into the second groove, and an upwardly projecting hanger structure on the base rearwardly of the first upwardly projecting structure.
Claim 2
Dependent Claim 149 words
A clip for hanging a frame comprising a base structure having a forward and rearward portion, downwardly projecting structure on the forward portion of the base structure for reception in a first groove of a frame member, first upwardly projecting structure on the base spaced rearwardly of the downwardly projecting structure, a flexible arm extending laterally from the fIrst upwardly projecting structure and terminating in a free end, second upwardly projecting structure on the arm spaced forwardly of the first upwardly projecting structure for reception in a second groove in a frame oppositely disposed from said first groove, whereby the clip may be mounted on a frame by inserting the downwardly projecting structure into the first groove and then depressing the arm and inserting the second upwardly projecting structure into the second groove, and an upwardly projecting hanger structure on the base rearwardly of the first upwardly projecting structure.
Claim 3
Dependent Claim 72 words
The clip of claim 1 and further characterized in that the first upwardly projecting structure comprises a lower portion and an upper portion, the upper portion being of reduced thickness with respect to the lower portion and being spaced rearwardly of the second upwardly projecting structure to define therewith a channel for reception of an edge portion of a frame wall which defines a portion of the second groove in the frame.
Claim 4
Dependent Claim 47 words
A clip as defined in claim 2 and further characterized in the provision of upwardly projecting structure on the free end of the flexible arm spaced rearwardly of the second upwardly projecting structure to define therewith a channel for reception of said edge portion of a frame.
Claim 5
Dependent Claim 48 words
A clip as defined in claim 1 and further characterized in that said second upwardly projecting structure has a downwardly inclined forward surface for camming engagement with said edge portion of a frame for depressing said arm to insert the second upwardly projecting portion into said second groove.
Claim 6
Dependent Claim 40 words
A clip as defined in claim 1 and further characterized in that said base structure comprises a pair of spaced-apart horizontally extending members joined together by the hanger structure and by a reinforcing bar extending therebetween intermediate the ends thereof.
Claim 7
Dependent Claim 52 words
A clip as defined in claim 5 and further characterized in that said downwardly projecting structure comprises a member projecting downwardly from each forward end of the base members and said first upwardly projecting structure comprises a member extending upwardly from each base member and spaced rearwardly of the downwardly projecting members.
