Poster display device with longitudinal retention of frame sections
First Claim
1. In a display holder having a plurality of elongated frame sections forming a frame structure for receiving and holding a display piece, each of said sections having a pair of elongated front and back members adapted to be assembled in an interconnected arrangement with one another, said front and back members being provided with coacting hinge formations integral therewith and in mating pivotal engagement with one another, the improvement wherein in said coacting hinge formations one of said elongated front and back members has a laterally recessed portion formed at a predetermined longitudinal position therein, the other of said elongated front and back members having a laterally-protruding discontinuity formed at a longitudinal position thereon corresponding to said predetermined longitudinal position of said laterally recessed portion when said front and back members are in said interconnected arrangement, said laterally-protruding discontinuity being longitudinally interlockingly received within said laterally recessed portion in order to provide a longitudinally interlocking interference and to substantially prevent longitudinal movement of said front and back members relative to one another when in said interconnected arrangement.

Abstract
An improved poster frame and display holder for replaceable posters and similar advertising material is disclosed. The sides of the frame include sets of pivotably engaged extruded metal, molded plastic, or other front and back frame members. Improved leaf-type springs bias together the front and back members of each side of the frame for releasably holding a poster or similar display. Interlocking portions of the front and back members substantially prevent relative longitudinal movement therebetween.

- 1. In a display holder having a plurality of elongated frame sections forming a frame structure for receiving and holding a display piece, each of said sections having a pair of elongated front and back members adapted to be assembled in an interconnected arrangement with one another, said front and back members being provided with coacting hinge formations integral therewith and in mating pivotal engagement with one another, the improvement wherein in said coacting hinge formations one of said elongated front and back members has a laterally recessed portion formed at a predetermined longitudinal position therein, the other of said elongated front and back members having a laterally-protruding discontinuity formed at a longitudinal position thereon corresponding to said predetermined longitudinal position of said laterally recessed portion when said front and back members are in said interconnected arrangement, said laterally-protruding discontinuity being longitudinally interlockingly received within said laterally recessed portion in order to provide a longitudinally interlocking interference and to substantially prevent longitudinal movement of said front and back members relative to one another when in said interconnected arrangement.
- 15. A display holder having a plurality of frame sections forming a frame structure for receiving and holding a display piece, each of said sections having an elongated front member and an elongated back member adapted to be assembled in a pivotal relationship with one another, said front member and said back member being provided with coacting hinge formations integral therewith and in mating pivotal engagement with one another, the improvement comprising in combination first channel means formed in said back member, second channel means formed in said front members, and a spring means positioned in and extending between said first and second channel means, said spring means comprising a generally planar piece of material without any bends or folds therein, and said first channel means substantially enclosing one end of said spring means and having an arcuate-shaped center portion flanked on both sides by substantially flat wall portions, one of said front and back members having a laterally recessed portion formed at a predetermined longitudinal position therein, the other of said front and back members having a laterally-protruding discontinuity formed at a longitudinal position thereon corresponding to said predetermined longitudinal position of said laterally recessed portion when said front and back members are assembled, said laterally-protruding discontinuity being longitudinally interlockingly received within said laterally recessed portion in order to provide a longitudinally interlocking interference and to substantially prevent longitudinal movement of said front and back members relative to one another when assembled.
- 22. A poster display frame having a plurality of frame sections for receiving, holding and displaying a display indicia, each of said frame sections comprising a front member and back member hinged together in a pivotal relationship to one another and a spring for biasing the front and back members together and holding them in closed and open positions for respectively clamping in place and removing said display indicia, said front member and said back member having coacting hinge formatins integral therewith and in mating pivotal engagement with one another, said spring extending between said front and back members and positioned in channels in each of said front and back members, the improvement wherein said channel in said back member has an arcuate-shaped center portion and two substantially flat side wall portions substantially enclosing one end of said spring in order to allow said one end of said spring to move in said channel in said back member but not be dislodged therefrom during pivotal operation of said front and back members, one of said front and back members having a laterally recessed portion formed at a predetermined longitudinal position therein, the other of said front and back members having a laterally-protruding discontinuity formed at a longitudinal position thereon corresponding to said predetermined longitudinal position of said laterally recessed portion when said front and back members are assembled, said laterally-protruding discontinuity being longitudinally interlockingly received within said laterally recessed portion in order to provide a longitudinally interlocking interference and to substantially prevent longitudinal movement of said front and back members relative to one another when assembled.
- 29. A display holder having a plurality of frame sections forming a frame structure for receiving and holding a display piece, each of said frame sections having a pair of front and back members adapted to be assembled in a pivoted relationship with one another, said front and back members being provided with coacting hinge formations integral therewith and in mating pivotal engagement with one another, the improvement comprising in combination first channel means formed in said back member, second channel means formed in said front member, and a spring means positioned in and extending between said first and second channel means, said spring means comprising a generally planar piece of material without any bends or folds therein and having a length greater than the distance between said first and second channel means so that said spring means is bowed when positioned therebetween, and said first channel means substantially enclosing one end of said spring means, one of said front and back members having a laterally recessed portion formed at a predetermined longitudinal position therein, the other of said front and back members having a laterally-protruding discontinuity formed at a longitudinal position thereon corresponding to said predetermined longitudinal position of said laterally recessed portion when said front and back members are assembled, said laterally-protruding discontinuity being longitudinally interlockingly received within said laterally recessed portion in order to provide a longitudinally interlocking interference and to substantially prevent longitudinal movement of said front and back members relative to one another when assembled.
