A hingeable plate assembly includes first and second substantially flat glass plates and first and second displaceable hinges for hingeably connecting the plates so that the second plate is outwardly displaceable with respect to the first plate in substantially parallel aligned relation thereto. The hinges each include first and second hinge pieces which are attached to the first and second plates, respectively, and pivot elements which are captured between the respective first and second hinge pieces thereof. The pivot elements are preferably formed as spherical balls which are received in elongated slots in the respective first hinge pieces thereof and sockets in the respective second hinge pieces thereof. The ball elements can rotate in the respective slots and/or sockets thereof to enable the second plate to be hinged relative to the first plate, and they can travel in the respective slots thereof to enable the second plate to be displaced outwardly from the first plate.
A displaceable hinge assembly comprising a first hinge piece securable to a first member, a second hinge piece securable to a second member, said first hinge piece having an elongated slot therein which faces said second hinge piece, said second hinge piece having a socket therein which faces said first hinge piece, a ball element received in said slot and said socket so that it is captured between said first and second hinge pieces, said ball element being longitudinally repositionable in said slot to enable said second hinge piece to be displaced outwardly relative to said first hinge piece in a direction substantially parallel to said slot and being rotatable relative to at least one of said first and second hinge pieces to enable said second hinge piece to be pivoted relative to said first hinge piece, and means maintaining said first and second hinge pieces in closely adjacent relation to thereby maintain said ball in said slot and said socket.
A hingeable plate assembly comprising first and second plates and first and second displaceable hinge assemblies hingeably connecting said first and second plates, each of said hinge assemblies comprising a first hinge piece attached to said first plate, a second hinge piece attached to said second plate, each of said first hinge pieces having an elongated slot therein which faces the respective second hinge piece thereof, the slots in the first hinge pieces of said first and second hinge assemblies being substantially parallel and facing in substantially opposite directions, each of said second hinge pieces having a socket therein which faces the respective first hinge piece thereof, a ball element received in the slot and the socket of each of said hinge assemblies so that it is captured between the respective first and second hinge pieces thereof, each of said ball elements being longitudinally repositionable in the respective slot thereof to enable the first plate to be displaced relative to the second plate and being rotatable relative to at least one of the respective first and second hinge pieces thereof to enable the first plate to be pivoted relative to the second plate, said first and second plates maintaining the respective first and second hinge pieces of said first and second hinge assemblies in closely adjacent relation to thereby maintain the respective ball elements thereof in the respective slots and sockets thereof.
A displacement hinge assembly comprising a first hinge piece securable to a first member and a second hinge piece securable to a second member, said first hinge piece having an elongated slot therein which faces said second hinge piece, a pivot element secured in a predetermined fixed location on said second hinge piece and received in said slot, said pivot element being longitudinally repositionable in said slot, and being rotatable relative to at least one of said first and second hinge pieces and means maintaining said first and second hinge pieces in closely adjacent relation to thereby maintain said pivot element in said slot.
A hingeable plate assembly comprising first and second plates and first and second displaceable hinge assemblies hingeably connecting said first and second plates, each of said hinge assemblies comprising a first hinge piece attached to said first plate and a second hinge piece atached to said second plate, each of said first hinge pieces having an elongated slot therein which faces the respective second hinge piece thereof, the slots in the first hinge pieces of said first and second hinge assemblies being substantially parallel and facing in substantially opposite directions, each of said hinge assemblies further comprising a pivot element received in the slot of the respective first hinge piece thereof, each of said pivot elements being longitudinally repositionable in the slot of the respective first hinge piece thereof and being rotatable relative to at least one of the respective first and second hinge pieces thereof, said first and second plates maintaining the respective first and second hinge pieces of said first and second hinge assemblies in closely adjacent relation to thereby maintain said pivot elements in the respective slots thereof.
