Abstract: A trolley rail system (10) for supporting and guiding a sliding cooler door (14) of a walk-in type cooler. The system has a guide rail (27) having two linear segments (29,30) and two deviation ramp portions (33,34), and an auxiliary rail (38). The system also has a leading trolley (41) and a trailing trolley (42). The leading trolley has a wheel (51) supported upon the guide rail. The trailing trolley has a primary wheel (52) supportable upon the guide rail and an auxiliary wheel (53) supportable upon the auxiliary rail.

Abstract: An insulated panel 10 has embedded hook fasteners 13 and hook fastener 14 mounted on opposite sides of the panel which are coupled tautly together by embedded, flexible straps 22, which are releasably coupled with the fasteners. This coupling is done by interlocking T-shaped ends 36 of the straps in T-shaped slots 33 formed in wing anchors portions 32 of the fasteners.

Abstract: The present invention teaches a modular fixture (also sometimes in the trade referred to as fixture-ware) system, the features of which include and are characterized by the user's ability to set the system up and "knock it" down without the need of tools. This attractive and unique fixture system includes one or more lockable bracket assemblies which may be lockably positioned at any one or more of several locking positions, while at the same time facilitating locking at any of a substantially infinite number of positions. At least one vertical support member is formed with what may to some look like an I-type beam configuration. The differences between this configuration and an actual conventionally used I-beam, however, are apparent. The bracket assemblies include non-vertical portions adapted to support hanging articles, such as by way of example only, clothing, which may be on hangers.

Abstract: A butt mounted riser hinge has a plastic cam assembly mounted in two metallic cylinders so that their camming surfaces do not rub against the metallic cylinders and become readily worn. The cam assembly includes a male member with bevelled end that is rotatably received in a cup-shaped female member. The hinge further includes a spring and shell assembly in sliding arrangement with one of the metallic cylinders.

Abstract: A socket for use in mounting a cylindrical leg to a table is comprised of a tube that has a generally cylindrical wall one end of which is inwardly flared to form a circular lip of a selected inside diameter substantially equal to the outside diameter of the leg. The generally cylindrical wall is formed with at least three inwardly projecting ribs that the located tangentially about a geometric cylindrical boundary of the same diameter as the selected inside diameter of the wall end lip.

Abstract: The present invention provides an improved panel fastener system for insulated slab panels of the type having one housing holding a hook assembly having a hook member and opposed hubs extending from a cam connected to the hook member; and a second housing having a pin adapted to receive the hook of the hook member. The invention provides an assembly method for mounting the hook member into the first housing including opposed resilient walls perpendicular to the front wall of the first housing forming a vertical slot adapted to receive the hook member. A pair of inclined planes lead from the rear portion of the housing to a pair of hub housing receptacles formed in the walls. The extended hubs are inserted into the slot from the rear of the housing along the inclined planes. The resilient walls are pressed back until the hubs reach the receptacles, at which time the biased walls snap back into their original configuration, capturing the hubs and the hook member in the first housing.

Abstract: A lock assembly features a removable cylinder plug. The cylinder plug is rotatably disposed in an outer body portion of the lock assembly that is itself movably positionable in a lock housing. The removable plug is only removable when the outer body portion of the assembly is disengaged from the housing. The body portion is disengageable when the inner plug member is rotated within the body portion after insertion of a key.
