ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to extruded elongated grip members for gripping and displaying sheet material such as posters or the like, which posters or the like are readily changeable as desired.
2. Prior Art
Poster gripping assemblies have been known in the field, for a number of years. One such instance is shown in U.S. Pat. No. 4,519,152 to Seely et. al. which shows a tamper proof poster display arrangement. This display arrangement has an outer cover portion with certain defined angles which make it difficult to open the cover from its base. An “opener tool” is required for that. The cover and the base portions are independently extruded and have a hinge relationship which requires a difficult “slide together” assembly. U.S. Pat. No. 4,937,959 to Palmer et. al. discloses a gripper extrusion arrangement wherein a front cover portion and a rear panel portion are separately extruded and mated together in another complicated hinge assembly. Inadvertent sliding between the front cover portion and the rear panel portion is prevented by a rather complicated discontinuity formed in the front panel which mates with a slot or the like in the rear panel. This requires further operations and unnecessary manufacturing costs. U.S. Pat. No. 5,307,575 to Ivansson et. al. shows a frame corner assembly wherein adjacent sides of a frame are held together with a rather complicated bracket arrangement. The cover portions and rear panel portions are individually extruded and are snapped together. Alignment of the ends of these multiple component arrangements lead to inaccurate end mis-aligned corner sections. U.S. Pat. No. 5,732,496 to Tanaka shows a sign frame with corner arrangements for attaching sides of that frame together. Mitered alignment of the corners is avoided by a corner insert which is somewhat more expensive to manufacture and adds a further step in that procedure.
It is an object of the present invention, to provide a poster gripping assembly which overcomes the disadvantages of the prior art.
It is a further object of the present invention to provide a poster gripping assembly which may be utilized in a poster-holding configuration by itself or in a frame construction of rectilinear configuration.
It is a further object of the present invention to provide a poster gripping assembly which simplifies the manufacturing operation over the prior art.
It is another object of the present invention to provide a poster gripping apparatus with a biasing spring arrangement which may be readily adjusted and re-conformed to permit adjustment of its bias.
It is yet still a further object of the present invention to provide a poster gripping assembly which may be assembled into a rectilinear frame construction with accuracy and simplicity while minimizing the likelihood of defects as may be associated with the prior art.
BRIEF SUMMARY OF THE INVENTION
The present invention comprises an elongated multiple component extrusion for the ready insertion and removal of a display poster therefrom. The elongated extrusion comprises an elongated back panel unitarily co-extruded with a front cover panel articulably connected thereto by a living hinge arranged connectively therebetween. The back panel has a forwardly directed face, a rearwardly directed or back face and a lowermost end. A rearwardly directed lower flange extends off of the lowermost edge of the rearward face of the elongated back panel. A middle flange, of “L”-shape in cross section, extends off of a midpoint of the back face of the elongated back panel.
An upper flange extends off of the back face of the upper end of the elongated back panel, having a lip thereof directed in opposition to the lip of the middle flange. The upper flange and the middle flange thereby defining a pair of opposed channels for sliding receipt of a securement means or a corner bracket therebetween.
A panel leg connects one edge of the living hinge to the proximal portion of the front cover panel. The panel leg and the front cover panel meet at an angle of about 90 degrees at a corner juncture therebetween. An elongated proximal lip is arranged at the juncture of the living hinge and the panel leg and is disposed at an angle of about 90 degrees with respect to the proximal end of that panel leg.
A frontwardly directed front web or bridge extends from the upper edge of the forwardly directed face of the elongated back panel in coextensive alignment with the leg of the upper flange thereof. An elongated, rearwardly directed “L”-shaped support flange is arranged at the distal end of the front web or bridge to define a channel which receives the proximal lip extending from the lower end of the panel leg. The front end or bridge also has a channel flange extending downwardly therefrom, parallel to the forward face of the elongated back panel.
A generally forwardly directed “C”-shaped receiving channel is co-extruded on the distal edge of that channel flange. The “C”-shaped receiving channel is defined by an arcuate segment of about 90 degrees, having a pair of linear first and second lips arranged perpendicularly with respect to one another. The first and second lips are spaced-apart at their distalmost edges to define a linear opening therebetween.
The front cover panel has a distalmost edge with a rearwardly directed flange extending therefrom. The rearwardly directed flange and the distalmost edge portion of the front cover panel define a “V”-shaped channel therebetween in cross-section. The rearwardly directed flange has an elongated distal foot co-extruded therewith. The distal foot is a linear extension, disposed generally perpendicularly to the plane defined by the front cover panel at its distalmost edge portion.
One or more shapable, elongated, generally sinusoidally-shaped wire-like springs are disposed between the elongated back panel and the elongated front cover panel. The elongated springs each have end portions which are generally parallel with one another. A first end portion of the elongated spring may be inserted within the generally “C”-shaped receiving channel facing forwardly from the elongated back panel. The elongated spring has a second end which may mate within the “V”-shaped channel formed at the rearward side of the distal end of the front cover panel.
In the fabrication of a frame assembly from the extruded back panel and front cover panel, each end thereof would be mitered into a 45 degree cut. Each mitered end would be then mated with a correspondingly mitered end of a further elongated back panel and elongated co-extruded front cover panel with an “L”-shaped bracket disposed at the juncture thereof lodged between the upwardly directed middle flange and the downwardly directed lip of the upper flange.
A backer board may be inserted within the receiving channel adjacent the uppermost edge of the forward face of each elongated back panel. A flexible poster may be disposed atop the backer board and the front cover panel pivoted downwardly about the support flange so that the spring biases the front cover panel and its distalmost foot therefrom, against the front surface of the poster on that backer board.
Thus has been shown a unique co-extruded poster gripping arrangement which may be assembled into a frame or utilized singularly to display a poster in an efficient and cost effective manner.
The invention thus comprises a multiple component gripper extrusion for the gripping support of a poster display arrangement, comprising: an elongated extruded back panel having a front face, a back face, a lower edge and an upper edge; an elongated extruded front panel with a panel leg at a proximal portion thereof and a channel at a distal edge thereof. The back panel and the front panel are integrally connected by a living hinge co-extruded simultaneously therewith. An elongated spring is adjustably disposed between the back panel and the distal edge of the front panel to permit controllable biasing of a poster supported on the back panel by the front panel. An upper flange and a middle flange are ar
