Abstract
Abstract A cabinet and kit for making the cabinet are disclosed in which the walls are structurally interlocked so that the cabinet can be assembled easily and quickly without tools. One of the interlocks comprise a pair of orthogonal channels and mortices which mate with orthogonal tenons. Another interlock comprises a mortice and tenon wherein a strap spans part of the mortice and locks with a bracket mounted in a recess in the tenon.

Claim 1
Independent Claim
372 words
A cabinet kit, cabinet or the like comprising a set of interlockable parts including a. a first end wall b. a second end wall c. a first side wall d. a second side wall e. at least one L-shaped member projecting from the interior surface of one of said first end wall and said first side wall, the L-shaped member and said interior surface forming a first channel, f. a first tenon projecting from the interior surface of said other of said first end wall and first side wall and being adapted to be slideably received within said first channel, g. a mortice orthogonal to said channel formed in one of said first end wall and first side wall, h. a second tenon orthogonal to said first tenon projecting from the other of said first end wall and first side wall and being adapted to be slideably received by said mortice, i. said second side wall having the same construction as the first side wall, j. a groove formed in the interior surface of one of said second end wall and first side wall and at least two spaced apart straps fixedly mounted on said interior surface across said groove, k. a tongue extending from the other of said second end wall and first side wall adapted to be slideably received within said groove, a pair of recesses formed in said tongue each recess being aligned with one of said straps and having a first and second portion, the first portion being deeper than the second portion, a bracket mounted in said second portion and having an outwardly sloped section, the end of said section being spaced longitudinally and transversely from the remote end of the first portion such that upon insertion of the tongue in the groove, the strap is received within the first portion and the bracket is received in the groove between the strap and the wall in which the groove is formed, when the second end wall and first side wall are slid relative to each other the sloped section of the bracket draws the second end wall and first side wall tightly together, 1. said second side wall having the same construction as said first side wall.
Claim 2
Dependent Claim

A cabinet kit, cabinet or the like comprising a set of interlockable parts including a. a first end wall b. a second end wall c. a first side wall d. a second side wall e. at least one L-shaped member projecting from the interior surface of one of said first end wall and said first side wall, the L-shaped member and said interior surface forming a first channel, f. a first tenon projecting from the interior surface of said other of said first end wall and first side wall and being adapted to be slideably received within said first channel, g. a mortice orthogonal to said channel formed in one of said first end wall and first side wall, h. a second tenon orthogonal to said first tenon projecting from the other of said first end wall and first side wall and being adapted to be slideably received by said mortice, i. said second side wall having the same construction as the first side wall, j. a groove formed in the interior surface of one of said second end wall and first side wall and at least two spaced apart straps fixedly mounted on said interior surface across said groove, k. a tongue extending from the other of said second end wall and first side wall adapted to be slideably received within said groove, a pair of recesses formed in said tongue each recess being aligned with one of said straps and having a first and second portion, the first portion being deeper than the second portion, a bracket mounted in said second portion and having an outwardly sloped section, the end of said section being spaced longitudinally and transversely from the remote end of the first portion such that upon insertion of the tongue in the groove, the strap is received within the first portion and the bracket is received in the groove between the strap and the wall in which the groove is formed, when the second end wall and first side wall are slid relative to each other the sloped section of the bracket draws the second end wall and first side wall tightly together, 1. said second side wall having the same construction as said first side wall.
Claim 3
Dependent Claim
30 words
A cabinet kit, cabinet or the like as defined in claim 1 wherein said L-shaped member and first tenon are formed from a plastic having a low coefficient of friction.
Claim 4
Dependent Claim
100 words
A cabinet kit, cabinet or the like as defined in claim 1 including a second mortice adjacent to a second edge in said first side wall and a third mortice adjacent to a second edge in said second side wall, said second and third mortices being orthogonal to said first end wall and a third end wall having a tongue on opposite sides thereof adapted to be slideably received within said second and third mortices third end wall and to abut an edge of said first end wall preventing sliding motion thereof relative to said first and second side walls.
