ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to gripping devices for securing one or more posters or signs and for holding together multiple sheets of papers or the like.
2. Prior Art
Posters and signs are required advertising in the commercial establishments such as stores and shops. These signs are of necessity supported in the most visible and presentable method possible. It is also most highly desired, to be able to adapt these signs or change them as the need arises. This is often fairly frequently in modem commercial establishments. To this end, they have been proposed a number of sign gripping components for such purposes.
U.S. Pat. No. 4,512,094 to Seely teaches a biasing means be integrally attached to both a cover and backing members for a frame support. The biasing means required of this patent are made of an extruded plastic material formed at the time of extrusion of the cover and backing members.
U.S. Pat. No. 4,512,095 to Seely shows a frame support with a biasing means which is integrally attached to a base member and a cover member, and the biasing means is co-extruded from a plastic at the same time as the base member and the cover member.
U.S. Pat. No. 4,519,152 to Seely et al. is directed to a tamper proof poster display with three frame surfaces of this complicated display having included angles of greater than 90 degrees therebetween.
U.S. Pat. No. 4,523,400 to Seely covers a plastic biased poster frame assembly. A biasing means is integrally attached to both a base member and a cover member, and the biasing means is formed by extrusion together with the base and cover members simultaneously.
U.S. Pat. No. 4,580,361 to Hillstrom et al. covers a display tensioning frame arrangement. A slide means in a base member, a tensioning means to tension the sign panel automatically when the sign is in position, or a clamp and spring arrangement for tensioning the sign or poster within the frame assembly is shown which complicates this device.
U.S. Pat. No. 4,937,959 to Palmer et al. covers a poster display device with a complicated longitudinal retention arrangement therewith. It teaches the use of a laterally protruding discontinuity and a laterally recessed portion formed in a front or back member to provide an interlocking interference.
U.S. Pat. No. 5,307,575 to Ivansson et al. relates to a framed corner assembly for posters. It teaches the use of an insert member or corner member with a rail hinge means, a gap means with an interference fit, and means to prevent sliding longitudinal movement of cover members.
U.S. Pat. No. 5,732,496 to Tanaka covers a sign frame arrangement with improved corner devices. It teaches using complicated corner members having a generally quadrant-shape and frame sections amongst other limitations, with the side surfaces and raised ridge members.
It is an object of the present invention to produce a sign gripping arrangement which includes the prior art.
It is a further object of the present invention, to provide a sign gripping arrangement which is literally changeable by a commercial store clerk with minimum training.
It is a further object of the present invention to provide a gripping apparatus which permits sign insertion and rigidity with minimal complexity.
BRIEF SUMMARY OF THE INVENTION
The present invention comprises an internal elongated extruded clip formed of a plastic material which is adapted and supported within an externally disposed elongated shell of extruded aluminum or the like. The elongated extruded clip comprises a generally linear, elongated backing base having a first or distalmost edge and a second or proximal edge defining a back plane. An elongated planar front member is disposed in a spaced apart parallel relationship to the planar backing base and is attached thereto by a bridge portion co-extruded therewith so as to hold the planar back base portion and the planar front member in a parallel and spaced apart manner.
An elongated support portion of T-shape in cross section has a leg which is unitary with the bridging portion of the extruded clip. The planar front member has an elongated distalmost edge which connects a pivotable first leg and second leg via a living hinge attached therebetween. The first leg and the second leg attached to the distalmost edge of the planar front member, are disposed at an angle of about 90 degrees to one another. The second leg has a distalmost portion which is unitarily attached to an elongated curvilinear foot which extends distally of the first or distalmost edge of the planar backing base. The first and second legs and the extended foot are arranged so as to be arcuately pivotable about the distalmost edge of the planar first member at the living hinge disposed therebetween.
The elongated shell or external portion of the present invention is preferably extruded from aluminum, and has an elongated generally C-shaped first opposed wall and an elongated generally C-shaped second opposed wall. Each first and second opposed walls have an uppermost edge and a lowermost edge which are spaced apart from one another. The first and second opposed walls are held in that spaced apart orientation by a bridging portion unitarily spaced therebetween adjacent the first end of each opposed wall. A U-shaped channel is disposed on an inwardly directed side of the bridging portion of the elongated shell, the U-shaped channel being defined by two L-shaped members, each having a distalmost edge directed towards and spaced apart from one another.
An L-shaped guide flange is arranged on the internal side of the first opposed wall and on the internal side of the second opposed wall adjacent their respective second ends. Each L-shaped guide flange has a side portion which is parallel to and spaced apart from its corresponding guide flange on its opposite wall.
In the assembly of the present invention, the internal portion, that is the elongated extruded clip, is slidably inserted within the central portion of the elongated shell between the first opposed wall and the second opposed wall. The T-shaped support on the second end of the elongated extruded clip is arranged to be slidably received within the distalmost opposed edges of the U-shaped channel extending downwardly from the bridging portion which supportably separates the first opposed wall from the second opposed wall of the elongated shell. The first or distalmost edge and the first and second legs and extended foot of the elongated extruded clip are arranged to be disposed and supported between the lowermost opposed edges of the first opposed wall and the second opposed wall to permit the extruded extended foot on the distal edge of the second leg, to be pivoted around the living hinge so as to permit insertion of a poster or the like between the planar backing base and the planar front member of the elongated extruded clip supported within the elongated shell.
The invention thus comprises an elongated shell and internal gripper assembly for gripping and supporting sheet-like posters or pictures for display purposes in a readily exchangeable manner. The assembly comprises an elongated, extruded gripper clip having a planar backing base pivotable distal-most poster receiving edge; an elongated, extruded receiving shell having a gripper clip receiving channel centrally arranged therein and also having an edge slot, wherein the gripper clip is slidably received within the receiving channel. The gripper clip has a distalmost receiving edge extending distally beyond said edge slot of the shell to permit display and exchange of a poster or picture therefrom. The distalmost receiving edge extends beyond a distalmost edge of the planar-backing base. The extruded shell comprises a pair of opposed C-shaped shell portions held in a spaced-apart manner by a unitary bridging member. The bridging member is arranged adjacent a first end of the spaced-apart shell portions. A U-shaped channel is arranged in an internal side of the bridging member to function as the receiving channel for the elongated gripping clip.
