Abstract: A trampoline convertible for use as a swimming pool includes a substantially rigid frame having a top member, a bottom member and a plurality of posts fixed between the top member and the bottom member to secure the members in spaced relationship to each other. A mat having a perimeter is planarly suspended relative to the top member. Also included is a shell having an outer perimeter and being insertable within a space defined by the frame. A plurality of shell attaching devices secures the shell to the frame. Overlapping the shell, a liner is included which is also positionable within the space defined by the frame. A plurality of liner attaching devices secures the liner to the frame. The trampoline is converted to a swimming pool by inverting the trampoline, securing the shell and the liner to the frame, and introducing water into the space defined by the frame and within the liner.

Abstract: A bracket for a wire shelf having at least one of an inner rod, an outer rod and a middle rod, the bracket extending generally normally to the rods upon installation and including an elongate body having an inner end for mounting to a substrate bracket, an outer end opposite the inner end, and an upper edge. The upper edge is provided with at least one groove for accommodating a corresponding one of the inner, outer and middle rods, each groove having an inner curved wall closer to the inner end, an outer curved wall closer to the outer end, and a floor connecting the inner and outer curved walls, the outer curved wall being vertically displaced from the inner curved wall so that the floor is inclined from the inner curved wall to the outer curved wall.

Abstract: A selective vertical locking mechanism is provided for use with a pair of telescoping tubes. A locking mechanism releasably locks the inner tube relative to the outer tube for adjustment of table height. The locking mechanism includes a housing disposed at the lower end of the inner tube. A locking element with the housing is biased against an inclined ramp fixed within the housing and, though an opening in the housing, against the inner wall of the outer tube, thereby preventing the inner tube from moving downwardly within the outer tube. A push rod and arm, actuated by a handle near the platform, pushes the locking element away from the inner wall or the ramp which allows the inner tube to move downwardly.

Abstract: A variable force clutch for use with a linear actuator power screw assembly including a threaded drive screw with a stop member secured at each end, the screw assembly used in an application apparatus having at least one cable provided with a barreled end for engaging the assembly. The clutch includes a nut configured for engagement in the bore and having a threaded interior surface for engaging the threads of the drive screw, a grooved exterior surface, upper and lower ends each having a stop lug, the nut being vertically movable resulting from axial rotation of the screw. At least one variable force clutch dog has a grooved formation for slidingly engaging the grooves on the nut, and a cable end retainer configured for securely retaining a barreled cable end.
