A ready-to-assemble (RTA) furniture system includes a collection of identically configured side panels, with sets of the side panels having different aesthetic and/or functional features, a collection of base panels and back panels spanning between pairs of side panels, the collection of base and back panels being provided in different sets of lengths and configurations to permit construction of different types of furniture. The panels are interconnected through a series of slots and notches. A ...

An automatically retracting chalk line assembly having both locking and braking means to lock the extended line in place and to slow the speed of retraction of the line during automatic rewind. The spool containing the line has an extended side in a hub cap shape which protrudes through a circular aperture in the housing. A slide member is moved out of a channel in this hub cap to form a friction lock with the housing. Braking is accomplished by slowing the spin of the hub cap by hand pressure.

A locking hinge assembly for mounting a visor on a helmet includes a cylindrical body which is fixed in an opening in the helmet and is loosely received through an aligned opening in the visor. The body has an annular detent flange with detent recesses therein in which are received detent studs carried by the visor for accommodating movement of the visor among a plurality of discrete detent positions. The locking assembly includes a shaft extending through an axial bore in the body and having an...

A tent includes a canvas and a frame. The canvas includes a rectangular floor piece and two pairs of opposite triangular side pieces thereby forming a substantially pyramid-like structure, the rectangular floor piece having a loop at each of four corners thereof. The frame includes two flexible triangular members respectively mounted to three sides of each of one pair of opposite triangular side pieces with top vertices of the triangular members meeting at an apex of the canvas. Each flexible tr...

In an assemble processing system, when a syntactical analysis procedure syntactically analyzes a source program, a macro definition procedure stores a macro definition program body of the source program in a macro definition area, and a macro reference procedure stores a macro formal parameter and a macro local symbol of the source program in a symbol table. After the operation of the syntactical analysis means is completed, the macro reference procedure deletes the stored macro formal parameter...

A ready to assemble construction system for erecting small structures such as houses, sheds, garages, etcetera. Comprising specially designed connecting plates which both secure laminate sections of lumber to each other to form constructive elements and also act as a rigid connecting means between the elements to enable the structure to be easily, quickly, and inexpensively built and later disassembled if necessary.

A combination table and bench includes a pair of substantially identical end supports made of bent round tubing. The end supports provide a series of horizontal planar slots. An elongate central slot receives a plurality of planks providing a table surface. A pair of lower slots receive planks to provide bench seating. The planks are sized to pass easily into the slots when the end supports are vertical. The end supports are inclined to bind the planks in position and thereby rigidify the combin...

A scroll compressor assembly includes a first linear drive for driving a first scroll along a first linear axis and a second linear drive for driving the first or second scroll along a second linear axis which is non-parallel to the first linear axis. Relative orbital movement between the first and second scrolls is obtained by controlling the frequency of oscillations of the first linear motor along a first linear axis and the second linear motor along the second linear axis. Further, capacity ...

To lock tubular frame members togethers, such as chair legs, shelf units and the like, a structural element has projecting ends which are profiled to fit within the tubular frame member. The ends are drilled transversely and tapped, and a counter sink is formed at one end of the tapped bore, into which a screw is inserted having a head which preferably has approximately the same diameter as the internal size of the tubular frame member. The drilled end, with the screw completely tightened into t...

A building side panel assembly, roof panel assembly, and roof beam are provided for modular construction wherein the panel assemblies may be inter-connected by an interlocking means which are located on each of the edges of the panel assemblies. The side panel assemblies are assembled in an edgewise relationship to form a structural barrier such as a wall. The panel assemblies are formed with a hemmed and a non-hemmed leg, wherein the non-hemmed leg of one panel assembly is configured to interlo...
