Abstract: A metal shelf lock, formed of metal for extra strength, and of improved construction is disclosed for securing shelves both vertically and horizontally in cabinets and the like. The shelf lock includes a unitary body formed of stainless steel, tempered steel, heat treated steel, spring steel, aluminum, brass or the like into essentially an L-shaped frame. The frame features an upright section and a horizontal section, with a flexible portion depending at an angle from the upright section and terminating in a tab. A hollow peg is formed in the upright section at about midway thereof and in operative association with the tab. The peg extends from the upright section in a direction opposed yet parallel to the horizontal section and at a distance less than the horizontal section. The hollow peg frictionally retains the metal shelf in a wall socket and is designed to receive the tab when the flexible portion is flexed by a shelf toward the upright section.
Abstract: A low profile shelf lock of improved construction is disclosed for securing shelves in cabinets and the like. The shelf lock includes a body portion formed of a bottom half and a top half resiliently joined thereto at an angle and defining a rectangular window. A resilient crescent-shaped protrusion is formed in the top half of the body portion and defines a shelf-engaging semicircular edge that extends substantially along the upper length of the window. A shelf support extends from the bottom half of the body portion in a direction normal thereto and flush with the bottom of the window. One or more reinforcing webs support the bottom of the shelf support to the bottom half of the body portion. A post extends from the bottom half of the body portion in a direction normal thereto but opposite to that of the shelf support and for a distance about one half of the shelf support. Preferably the post is fluted. Preferably, the angle between the top half and the bottom half of the body portion is about nine degrees.
Abstract: A universal single roller bracket is disclosed for use with sliding drawers in cabinets, bureaus, chests and the like. The universal single roller bracket is self-positioning and has no right or left-handed characteristics. It includes a unitary bracket, formed either of a high impact strength plastic material or of metal. A pair of flat mounting flanges, formed integral with the bracket, extend at an angle in respective divergent planes from an apex and define an axis adjacent the apex. A pair of parallel spaced roller supports, also formed integral with the bracket, extend from the apex in planes normal to the axis and connecting with the mounting flanges. A roller, formed of a high impact strength plastic material, is supported within the roller supports for rotation about the axis. The roller can be provided with a flanged shoulder to serve as a side guide for the drawers. In the alternative, one of the pair of roller supports can be formed with shoulders for serving as the side guide.
Abstract: A handle is provided for use with an Allen wrench by means of which leverage and grip on the wrench is improved and protection is provided in the event that the wrench should break during use. The handle is comprised of an elongated shank portion having an axial passage therein to receive the long end of the wrench. A head is provided at the end of the shank portion and formed with a recess perpendicular to and open to the shank passage to receive the short end of the wrench. Releasable retaining means are provided to hold the end of the wrench within the handle during operation thereof.
Abstract: A resilient roller guide assembly is provided for use with sliding drawers in cabinets, bureaus, chests and the like. The assembly includes an angle bracket having a pair of mutually perpendicular legs on each of which is mounted a roller rotatable about an axis parallel to the leg length and extending from one face of the leg. From the opposite face of the leg, at the inner edge thereof, is a lip adapted to seat against the edge of the opening in the cabinet through which the drawer moves. The rollers are of a diameter sufficient to engage and support the drawer at its bottom and along both sides when a unit is mounted at each lower corner of the drawer opening.
Abstract: A clip is provided for mounting panels such as false drawer fronts to cabinets. The clip is a one-piece device formed with a flat flange base attached to the rear face of the panel and includes a plurality of resilient prongs of different lengths extending perpendicularly from the base. Each prong includes a shoulder adapted to hook over the cabinet stile, and the shoulders, being at different distances from the base, permit one clip to be used for stile stock of various thicknesses and yet maintain tight locking engagement of the panel. The end of each clip is formed with an inclined cam leading edge by which the prong may be deflected while the panel is being installed.
Abstract: A drawer of the sort used in cabinets, desks, files and the like is supported for sliding movement by a single self-aligning center rail. The rail is mounted to the cabinet frame preferably above the drawer, extending from front to back. It is supported at its forward end by a bracket in fixed position and at the rear end by a cup-shaped receptacle allowing limited lateral movement of the rail end. A bifurcated drawer guide is attached at its lower end to the back wall of the drawer and at its upper end slidably engages the rail. The rail is tubular for the major portion thereof while the forward end is flattened to provide a partial stop action for the drawer and also provide means for the drawer to be fully removed. Low friction guide plates are mounted about the drawer opening for quiet, easy movement thereof.
