Abstract

Abstract A module capable of being grouped into multiples to define various articles of furniture, such as bookcases and file cabinets. The module is constituted by top, bottom and side panels whose edges have longitudinal bores therein and are cut to form complementary tongues and grooves creating corner joints, whereby the panels may be compactly packaged and shipped in the flat state and thereafter assembled on a site to create a box-like module having rectangular front and rear openings. The joints are held together and the structure stabilized by a removable strut connector constituted by a pair of intersecting arms each acting as a bridge between a set of diagonally-opposed corners at the rear opening to form a truss, the arms being pivotally interconnected and being provided at their ends with laterally-extending pins that are insertable into the corner bores so that one may collapse the module simply by removing the strut connector.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 140 words
A knock-down module for creating articles of furniture, the module comprising: A. four panels which define the upper, lower and side walls of the module, the edges at opposite ends of each panel having longitudinal bores therein, the edges of the top and bottom panels being cut to define intermediate tongues and the edges of the side panels being cut to define complementary grooves, whereby the panels may be assembled in edge-to-edge relation to create an open box-like structure having rectangular front and rear openings; and B. a strut connector which combines with the panels to create a trussed structure, said connector being formed of a pair of intersecting arms, each arm bridging a set of diagonal corners in the rear opening and having pins extending laterally therefrom which are insertable in said bores to hold the jointed corners together.
Claim 2
Dependent Claim 140 words
A knock-down module for creating articles of furniture, the module comprising: A. four panels which define the upper, lower and side walls of the module, the edges at opposite ends of each panel having longitudinal bores therein, the edges of the top and bottom panels being cut to define intermediate tongues and the edges of the side panels being cut to define complementary grooves, whereby the panels may be assembled in edge-to-edge relation to create an open box-like structure having rectangular front and rear openings; and B. a strut connector which combines with the panels to create a trussed structure, said connector being formed of a pair of intersecting arms, each arm bridging a set of diagonal corners in the rear opening and having pins extending laterally therefrom which are insertable in said bores to hold the jointed corners together.
Claim 3
Dependent Claim 23 words
A module as set forth in claim 1 wherein said arms are interpivoted by a rivet going through the intersection of the arms.
Claim 4
Dependent Claim 16 words
A module as set forth in claim 1, wherein said pins are integral with said arms.
Claim 5
Dependent Claim 24 words
A module as set forth in claim 3, wherein said arms are formed by metal rods having right angle ends to form said pins.
Claim 6
Dependent Claim 20 words
A module as set forth in claim 1, wherein said panels are formed of wood and said connector of metal.
Claim 7
Dependent Claim 25 words
A module as set forth in claim 1, wherein said connector arms are formed by slats having end holes through which headed pins are inserted.
Claim 8
Dependent Claim 18 words
A module as set forth in claim 1, further including a hinged door to close the front opening.
Claim 9
Dependent Claim 19 words
A module as set forth in claim 1, further including drawers sliding into said module through said front opening.
