Abstract
Abstract Dismountable furniture comprising two or more vertical members, and a plurality of horizontal members, a plurality of upwardly directed V-shaped recesses formed in inwardly facing surfaces of said vertical members, a vertical end wall fastened to each end of each said horizontal member, a downwardly facing V-shaped recess formed in the outwardly facing surface of each said vertical end wall, and, at least two joining members, each said joining member having two generally V-shaped locking portions, having inner and outer sides, and being integrally joined between their inner sides, thereby locating said V-shaped locking members in spaced apart parallel planes, with their apices overlapping, and extending in opposite directions, with one of said V-shaped locking members being dimensioned to be received in one of said V-shaped recesses in said vertical members, and the other of said V-shaped locking members being dimensioned to be received in said V-shaped recess of said vertical end walls. Also disclosed is dismountable furniture having two or more vertical members lying in a common plane, as in a wall or panel, and having a plurality of such upwardly directed V-shaped recesses formed in surfaces thereof, and at least one horizontal member having a vertical back wall, and there being at least two downwardly facing V-shaped recesses formed in the rear surface of said back wall, said upwardly and downwardly V-shaped recesses receiving two or more such joining members.

Independent Claim
176 words
Dismountable furniture comprising; at least two vertical members; a plurality of horizontal members; a vertical end wall attached to each end of each said horizontal member; a plurality of upwardly directed V-shaped recesses formed in inwardly facing surfaces of said vertical members; a downwardly facing V-shaped recess formed in the outwardly facing surface of each said vertical end wall of each said horizontal member, and, at least two joining members, each said joining member having two generally V-shaped locking portions, having inner and outer sides, and being integrally joined between their inner sides thereby locating said V-shaped locking members in spaced apart parallel planes, with their apices overlapping and extending in opposite directions, with one of said V-shaped locking members being dimensioned to be received in one of said V-shaped recesses in said vertical members, and the other of said V-shaped locking members being dimensioned to be received in said V-shaped recess of said vertical end walls, whereby said horizontal members may be supported between said vertical members, by interlocking engagement of said V-shaped locking members.
Claim 2
Dependent Claim
176 words
Dismountable furniture comprising; at least two vertical members; a plurality of horizontal members; a vertical end wall attached to each end of each said horizontal member; a plurality of upwardly directed V-shaped recesses formed in inwardly facing surfaces of said vertical members; a downwardly facing V-shaped recess formed in the outwardly facing surface of each said vertical end wall of each said horizontal member, and, at least two joining members, each said joining member having two generally V-shaped locking portions, having inner and outer sides, and being integrally joined between their inner sides thereby locating said V-shaped locking members in spaced apart parallel planes, with their apices overlapping and extending in opposite directions, with one of said V-shaped locking members being dimensioned to be received in one of said V-shaped recesses in said vertical members, and the other of said V-shaped locking members being dimensioned to be received in said V-shaped recess of said vertical end walls, whereby said horizontal members may be supported between said vertical members, by interlocking engagement of said V-shaped locking members.
Claim 3
Dependent Claim
55 words
Dismountable furniture as claimed in claim 1 wherein said V-shaped recesses are formed with inwardly undercut faces, and the V-shaped locking members are formed with corresponding angled mating faces, such that when a said V-shaped locking member is placed in its corresponding V-shaped recess and moved axially therein a two dimensional wedging effect is acheived.
Claim 4
Dependent Claim
57 words
Dismountable furniture as claimed in claim 1 wherein said vertical members are provided with a plurality of such V-shaped recesses aligned along a central axis of such vertical member, and including joining recess means, joining said V-shaped recesses whereby to provide a continuous elongated irregular recess along the length of a major portion of such vertical member.
Claim 5
Dependent Claim
13 words
Dismountable furniture as claimed in claim 1, wherein said horizontal members comprise shelves.
Claim 6
Dependent Claim
29 words
Dismountable furniture as claimed in claim 3, wherein at least some of said horizontal members comprise one or more storage units such as a drawer unit or the like.
Claim 7
Dependent Claim
83 words
Dismountable furniture as claimed in claim 5, including elongated V-shaped recesses formed in vertical end walls of said storage unit, generally V-shaped insert portions, dimensioned to be received within said V-shaped recesses, and being removeably insertable therein, at least two vertically spaced V-shaped recesses formed in each said insert portion, each of said V-shaped recesses being dimensioned and adapted to receive a said V-shaped locking member therein, with said spaced apart V-shaped recesses registering with respective spaced apart recesses in said vertical members.
Claim 8
Dependent Claim
169 words
Dismountable furniture comprising; at least two vertical members; at least one horizontal member adapted to extend between said vertical members; vertical mounting wall means attached to said horizontal member; a plurality of upwardly directed V-shaped recesses formed in surfaces of said vertical members; at least two downwardly facing V-shaped recesses formed in said vertical mounting wall means, and, at least two joining members, each said joining member having two generally V-shaped locking portions, having inner and outer sides, and being integrally joined between their inner sides, thereby locating said V-shaped locking members in spaced apart parallel planes, with their apices overlapping and extending in opposite directions, with one of said V-shaped locking member being dimensioned to be received in one of the V-shaped recesses in said vertical members, and the other of said V-shaped locking members being dimensioned to be received in said V-shaped recess of said vertical wall means, whereby said horizontal member may be supported between said vertical members, by interlocking engagement of said V-shaped locking members.
