Abstract

Abstract A knock-down furniture system is formed around a basic unit of at least one set of two side panels and top and bottom panels which can be assembled in edge-to-edge relationship to form a basic unit of four walls formed by the panels. Each two of these panels has edge sections which when the unit is assembled, are mutually adjacent, and these sections are formed to provide a dovetail joint therebetweeen with a male joint portion on one of these sections and a female joint portion in the other of the sections. These joints are formed with relatively large fitting tolerances so that the panels may be produced and assembled by unskilled labor. Those of the panels having female joint portions are formed with holes extending entirely through their edge portions and opening into the female joint portions or cuts, and the panels having the male joint portions have holes entering the male portions and which register with the first-named holes when the joint portions are interfitted. The joints are held together by pins proportioned for sliding insertion through the holes in the sections having the female portions and projecting into the holes in the male portions; these pins being insertable via the side ends of the assembled unit. Other components permit this basic unit to be provided with hinged doors, drawers, etc., all components of the system being essentially flat panels, easily manufactured and shipped and easily transported to the location requiring furnishing.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 168 words
A knock-down furniture system comprising at least one set of two side panels and top and bottom panels which can be assembled in edge-to-edge relationship to form a basic unit having four walls formed by said panels, each two of said panels having edge sections which when said unit is assembled, are mutually adjacent and formed to provide a dovetail joint therebetween with a male joint portion in one of said sections and a female joint portion in the other of these sections, said panels having said female joint portions being formed with holes extending entirely through their said edge sections and open into said female joint portions, and said panels having said male joint portions having holes entering into their said male joint portion and which register with the first-named holes when said joint portions are interfitted, and pins proportioned for insertion through said holes in said sections having said female portions and projection into said holes in said male portions, for releasably interfastening said dovetail joints.
Claim 2
Dependent Claim 168 words
A knock-down furniture system comprising at least one set of two side panels and top and bottom panels which can be assembled in edge-to-edge relationship to form a basic unit having four walls formed by said panels, each two of said panels having edge sections which when said unit is assembled, are mutually adjacent and formed to provide a dovetail joint therebetween with a male joint portion in one of said sections and a female joint portion in the other of these sections, said panels having said female joint portions being formed with holes extending entirely through their said edge sections and open into said female joint portions, and said panels having said male joint portions having holes entering into their said male joint portion and which register with the first-named holes when said joint portions are interfitted, and pins proportioned for insertion through said holes in said sections having said female portions and projection into said holes in said male portions, for releasably interfastening said dovetail joints.
Claim 3
Dependent Claim 19 words
The system of claim 1 in which said dovetail joint members interfit loosely, avoiding precision manufacture of said set.
Claim 4
Dependent Claim 48 words
The system of claim 1 having two of said sets for the assembly of two of said basic units for stacking one on top of the other, and links having holes through which said pins of the stacked units can be passed for linking the two units together.
Claim 5
Dependent Claim 111 words
The system of claim 1 in which said top and bottom panels have blind holes formed in their insides adjacent at least one open end formed by said basic unit when assembled, and the system includes at least one support member proportioned to fit inside of at least one of said side panels adjacent to said open end and having ends extending to said insides and having end holes which can be registered with said blind holes, and pins insertable in said blind and end holes during assembly of said unit, to fasten said support member to said insides and against the inside of said one of the said side panels.
Claim 6
Dependent Claim 33 words
The system of claim 4 in which said support member has hinges and a door for said open end of said basic unit and which is connected to said member by said hinges.
Claim 7
Dependent Claim 19 words
The system of claim 4 in which said holes have metal bushings, said panels being made of non-metallic material.
Claim 8
Dependent Claim 43 words
The system of claim 4 having two of said support members, one for the inside of each of said side panels, said support members being dimensioned to extend for substantially the depth of said side panels and having drawer slides on their insides.
Claim 9
Dependent Claim 36 words
The system of claim 7 including a drawer dimensioned for sliding in said drawer slides, said drawer being formed by four sides interhinged to fold flat and to be unfolded for insertion in said drawer slides.
Claim 10
Dependent Claim 53 words
The system of claim 8 having a third one of said members and having hinges and a door for said open end of said basic unit and which is connected to said third member by said hinges, said third member and said two of said members being interchangeably applicable to said basic unit.
Claim 11
Dependent Claim 44 words
The system of claim 9 in which said third member and its hinges and door fold into a flat assembly so that said basic unit, drawer and door, and said support members may, when unassembled, be handled and transported as stacks of flat parts.
Claim 12
Dependent Claim 21 words
The system of claim 2 in which said panels have adjacent edges which are transversely rounded to render said looseness unconspicuous.
