Abstract: A safety lock device including a clover mechanism mounted on a rotating shaft to be used with an unbalanced free-fall dog that precludes rotation of the rotating shaft upon rapid acceleration or excessive speed of the rotation of the shaft. The free-fall dog is pivotally mounted on a fulcrum upon which the free-fall dog may teeter in an unbalanced seesaw motion. At opposite ends of the fulcrum are a locking finger and an arm. The free-fall dog is unbalanced such that the arm contacts the clover mechanism as it rotates while the locking finger does not contact the clover mechanism at slow rotating speed. At a slow rotative speed, the arm is only slightly deflected. With great acceleration, the arm is deflected farther from the clover mechanism thereby causing the locking finger on the opposite side of the fulcrum to be pivoted into the clover mechanism.

Abstract: A shelving system employing an array of vertical standards defining vertically arranged pockets on the inwardly facing surface of each and a shelf. The shelf is rectangular and is formed from a single sheet of metal to which shoulder rivets are secured. The rivet heads extend outwardly of the side edges of the shelf and are arrayed to cooperate with a set of pockets to support and retain a shelf in association with the array of vertical standards.

Abstract: A pharmacy shelving array is described which has a plurality of side-by-side, open-faced fixed shelving columns and a plurality of side-by-side, track mounted, roller supported movable shelving units parallel to and closely adjacent to the fixed columns. Tracks lying parallel to the front faces of the open-faced fixed shelving columns and having end stops adjacent their ends are provided. Each movable shelving unit has a back, an open front, sides, a top and a bottom, and a plurality of shelves extending between the sides. A guide adjacent the top and parallel to the track is provided for stabilizing the movable shelving units against tipping. A self-priming deceleration system is provided adjacent the side of each movable shelving unit for engaging a next adjacent shelving unit or end stop for slowing movement of the movable shelving unit as it moves in the direction thereof along the track.

Abstract: A battery operated, rotatable platform display device for use in retail establishments. The display device employs a friction clutch provided between the base of the rotatable platform and an underlying drive plate upon which the rotatable platform is supported via a rotatable drive shaft.

Abstract: An archive, storage-rack assembly which is relatively easy to assemble, which provides considerable space-savings, which is relatively less costly to make, and which is relatively more stable. The archive storage-rack assembly of the invention is provided with four, specially-designed, corner-column supports. Operatively, and removably, associated therewith are shelf-clip units for supporting shelves. Each shelf-clip unit is one integral unit having two, end clip-sections for placement into respective openings of two, corner-column supports and for supporting a shelf-corner, an elongated, reinforcing angle-bracket section integral with, and interconnecting, the two, end-clip sections, and an elongated, box-guide section integral with, and projecting upwardly from, the elongated, reinforcing angle-bracket section. Each clip-assembly has a length extending in the direction of the depth of the rack-assembly, with a lateral pair of end-column supports supporting it via the two, integral, end-clip sections.

Abstract: A modular fitting room for retail store use. The fitting room provides side and front panels to define an interior space. A door panel is provided with laterally extending formations which cooperates with studs to prevent viewing of the interior space from outside of that space. Studs for mounting the door panel and for facilitating the assembly of the fitting room are also described.

Abstract: A pallet rack lock for use in a pallet rack system releasably locking one end of a shelf beam to an upright column is the subject matter of this invention. The column has a plurality of vertically spaced locking apertures. The rack lock includes a rock lock plate fixed to the shelf beam and positioned substantially parallel to the upright column. A load bearing stud is fixed to the lock plate. The stud is positioned in a lower portion of a locking aperture. A resilient carrier has one end fixed to the locking plate and the opposed end being free. A lock stud is mounted on the resilient carrier for movement therewith. The lock stud is positioned in an upper portion of a locking aperture to prevent upward movement of the load bearing stud. A dog limits the movement of the resilient carrier away from the lock plate. The lock stud may be selectively moved out of its locking aperture by bending a portion of the resilient carrier.
