Abstract: A wheel chock has an elongated body with a triangularly shaped cross section defined by the widths of a flat bottom surface and a pair of flat side members. A first end of the body has integral handle means extending away from the bottom surface and having grip means positioned a preselected distance from the bottom surface. The other end of the body is flat and transverse to the longitudinal axis of the body to facilitate the optional standing the body “on end”.

Abstract: A hand-held guidance wand for use by a grounded human to guide a moveable dirigible craft. The wand comprises a straight, longitudinally elongated, polygonal-cross-sectioned member. The wand is preferably hollow and has either a triangular or a square cross-section.

Abstract: A dynamic, wind powered decoy having a body member (with a longitudinal axis), rod means connected to the body member and extending longitudinally away from the body member, and a wing assembly rotatably mounted on the rod means. The decoy has pivot means in the body member defining a pivot axis at a selected angle from the longitudinal axis. When the decoy is pivotally supported, the wing assembly rotates about the longitudinal axis and the decoy rotates about the pivot axis to a heading whereat the body member is headed into the wind.

Abstract: An off-road in-line skate which includes a plurality of wheels mounted to a frame of a skate where the wheels each have a diameter in the range of 40 to 60% of the length of a boot of the skate to provide a maximum wheel diameter to clear obstructions while presenting an overall wheel base length less than a maximum wheel base length which would otherwise cause tripping during cross-over skating.

Abstract: An in-line skate has a fastening system which includes a strap having a first end and a second end each secured to a same side of the skate. A buckle is provided for releasably securing one of the first and second ends to the side. A first fastening member is secured to the strap at a point between the first and second ends. A second fastening member is secured to the boot on a side opposite the side on which the strap ends are fastened. The first and second fastening members may be releasably joined and tensioned.

Abstract: A transanal inserter is disclosed which facilitates the atraumatic insertion of intra-anal surgical devices through the anus. The inserter has a tubular portion, a prolate distal end and a proximal end having a flange associated therewith. The prolate end is formed from a plurality of petal-shaped segments which deflect outward as an intra-anal surgical device is urged therethrough, into the colon or intestine. The flange formed at the proximal end of the inserter retains the inserter in place and prevents over insertion of the inserter beyond the anus. The inserter can be fabricated in varying lengths to accommodate surgical requirements. The inserter is fabricated from a plastic material with sufficient pliability to provide for deflection of the segments, while maintaining sufficient rigidity to prevent collapse of the inserter during insertion and use.
