Abstract

Abstract A joint assembly for the fabrication of building units, furniture, display cases and the like, including basically at least two main joint bodies having a plurality of panel receiving grooves, each formed in a different direction, and a plurality of coupling grooves for combining the two main joint bodies. The coupling grooves are provided on the bottom of the joint main bodies and coupling pins are used to couple at least two such bodies with each other. The panel receiving grooves are each provided with two opposite side walls formed to have at least the forward and upper sides opened. The inner side faces of the respective side walls are inclined and provided with a plurality of dovetail grooves. A pair of wedges are associated with each panel receiving groove. Each wedge has two sides faces, one of which acts to fit on a panel end portion, and the other of which is provided with dovetail protrusions. The use of these wedges allows panels of uniform or different thicknesses to be combined. By this construction, the present joint assembly offers easy connection of panels without the need of any other supporting elements.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 154 words
A joint assembly for connecting a plurality of panels of appropriate thickness, each in a different direction, comprising a main joint body having a base and at least two panel receiving grooves, each directed in a different direction and mounted on said base, said panel receiving grooves each comprising an end wall, a bottom wall, and two opposite side walls, the remaining uppermost and outermost ends of said grooves being open, the inner side faces of said two side walls diverging away from each other toward the open forward side and being provided with a plurality of dovetail grooves; and a pair of wedges engagable with each of said panel receiving grooves, one side face of each of said wedges being provided with dovetail protrusions corresponding to the dovetail grooves of said panel receiving grooves and the inner side faces of said wedges being suited to fit on the side faces of the panels.
Claim 2
Dependent Claim 154 words
A joint assembly for connecting a plurality of panels of appropriate thickness, each in a different direction, comprising a main joint body having a base and at least two panel receiving grooves, each directed in a different direction and mounted on said base, said panel receiving grooves each comprising an end wall, a bottom wall, and two opposite side walls, the remaining uppermost and outermost ends of said grooves being open, the inner side faces of said two side walls diverging away from each other toward the open forward side and being provided with a plurality of dovetail grooves; and a pair of wedges engagable with each of said panel receiving grooves, one side face of each of said wedges being provided with dovetail protrusions corresponding to the dovetail grooves of said panel receiving grooves and the inner side faces of said wedges being suited to fit on the side faces of the panels.
Claim 3
Dependent Claim 154 words
A joint assembly for connecting a plurality of panels of appropriate thickness, each in a different direction, comprising a main joint body having a base and at least two panel receiving grooves, each directed in a different direction and mounted on said base, said panel receiving grooves each comprising an end wall, a bottom wall, and two opposite side walls, the remaining uppermost and outermost ends of said grooves being open, the inner side faces of said two side walls diverging away from each other toward the open forward side and being provided with a plurality of dovetail grooves; and a pair of wedges engagable with each of said panel receiving grooves, one side face of each of said wedges being provided with dovetail protrusions corresponding to the dovetail grooves of said panel receiving grooves and the inner side faces of said wedges being suited to fit on the side faces of the panels.
Claim 4
Dependent Claim 154 words
A joint assembly for connecting a plurality of panels of appropriate thickness, each in a different direction, comprising a main joint body having a base and at least two panel receiving grooves, each directed in a different direction and mounted on said base, said panel receiving grooves each comprising an end wall, a bottom wall, and two opposite side walls, the remaining uppermost and outermost ends of said grooves being open, the inner side faces of said two side walls diverging away from each other toward the open forward side and being provided with a plurality of dovetail grooves; and a pair of wedges engagable with each of said panel receiving grooves, one side face of each of said wedges being provided with dovetail protrusions corresponding to the dovetail grooves of said panel receiving grooves and the inner side faces of said wedges being suited to fit on the side faces of the panels.
Claim 5
Dependent Claim 165 words
A joint assembly for connecting a plurality of panels, each in a different direction as defined in claim 1, wherein at least two of said main joint bodies are coupled with each other at the bottom faces of their bases, each body being provided with an elongated cavity located in the base beneath the bottom wall of said panel receiving grooves, each cavity being open at the bottom face of the base; pin holes on the forward side of said bases communicating with the interior of said cavities, elongated coupling means having substantially the same shape as said cavities, but having twice the height thereof and being insertable into said cavities, said coupling means having two threaded bores which register with said pin holes when inserted into said cavities; and two pins for fixedly mounting said main joint bodies on said coupling means, said pins having a male threaded portion on one end and passing through said pin holes then screwed into said threaded bores.
Claim 6
Dependent Claim 103 words
A joint assembly for connecting a plurality of panels, each in a different direction as defined in claim 1, wherein at least two of said main joint bodies are coupled with each other at the bottom faces of their bases; the bottom faces being provided with dovetail shaped groOves running parallel to the bottom walls of said panel receiving grooves; and a pin in the form of two such dovetail grooves as said dovetail-shaped grooves are arranged symmetrically to each other and being insertable into the dovetail grooves when the bottoms of the two main joint bodies are in registration with each other.
Claim 7
Dependent Claim 55 words
A joint assembly for connecting a plurality of panels, each in a different direction as defined in claim 2, wherein said main joint bodies are each further provided with half of a panel receiving groove in the base thereof which forms a full panel receiving groove when the two main joint bodies are coupled together.
