Abstract: A knee pad assembly is disclosed to protect the knee of a workman who kneels down while working on a work surface. The knee pad assembly includes a flexible upper knee cushion at which to receive and cover the workman's knee and a rigid lower base that lies on the work surface below the upper knee cushion. The lower base has a continuously curved bottom to rock back and forth on the work surface when the workman shifts his weight while kneeling. The upper knee cushion and the lower base are held one above the other against the knee of the workman by a knee pad strap that is wrapped around the workman's leg. A pair of springs (e.g., flexible carbon fiber sheets having a spring memory) extend across the lower base below the upper knee cushion so as to suspend the workman's knee above the work surface and flex in response to the workman's knee pushing down on the knee cushion.

Abstract: An adjustable leg support for providing support to and stabilizing a leg of a table, chair or similar article that is shorter than the other legs to prevent the article from wobbling. The adjustable leg support includes a screw-threaded rotatable base that is detachably coupled in surrounding engagement to a correspondingly threaded platform. The platform has a flat shelf that is laid upon the floor below the short leg to be supported. A rotational force is applied to the rotatable base which causes an axial displacement of the platform upwardly through the base towards the short leg. Rotation of the base continues until the flat shelf of the platform is raised and the short leg is seated on the shelf by which to eliminate the gap between the short leg and the floor. The rotatable base and the platform are mated to one another along opposing sets of screw threads that lie outside and surround the short leg to be stabilized.

Abstract: An improved rotatable wedge spacer to be removably positioned in a gap between opposing upper and lower surfaces (e.g., tiles) that are being bonded (e.g., by means of mortar) one above or adjacent the other to a flat surface (e.g., a wall or a floor). The spacer includes a curved (e.g., circular) body having a thin tip at one end and a thick tail at the opposite end. The height of the circular body between an upward sloping top surface thereof and a flat bottom surface increases from the thin tip to the thick tail. A series of flat load-supporting plateaus having predetermined increasing heights are regularly spaced from one another along the top surface so as to lie parallel with the flat bottom surface. With the flat bottom surface of the wedge spacer seated upon the lower tile, the curved body is rotated within the gap until one of the flat load-supporting plateaus along the top surface engages the upper tile.

Abstract: A rotatable wedge tile spacer to be removably positioned in a gap between adjacent upper and lower tiles that are being bonded one above the other to a vertical surface (i.e., a wall). The tile spacer includes a curved (i.e., circular) body having a thin tip at one end and a thick tail at the opposite end. The height of the circular body increases along a tile-supporting top surface thereof that runs from the thin tip to the thick tail. With the tile spacer seated upon the lower tile, the circular body is rotated continuously around its longitudinal axis until the tile-supporting top surface engages the upper tile. Accordingly, the circular body of the rotatable wedge tile spacer will fill the gap and thereby prevent the upper tile from moving through the gap towards the lower tile during the bonding process.

Abstract: A flexible knee pad of the kind to be worn over the knee of a workman who must kneel down for long periods of time while working on a work surface. According to a preferred embodiment, the flexible knee pad includes an upper knee support cushion against which the workman's knee is laid, a lower pivot support base to rest upon the work surface, and an intermediate pivoting reinforcement plate having a flat bed upon which the knee support cushion is seated. The intermediate pivoting reinforcement plate includes a pair of pivots that are coupled to respective pivot slots formed in the lower pivot support base. Accordingly, the pivoting reinforcement plate, the knee support cushion seated thereon, and the workman's knee are all suspended by and rotatable relative to the pivot support base above the work surface so as to advantageously reduce pressure applied to the workman's knee cap by the work surface should he rock his body and shift his weight back and forth over the work surface.
