Abstract: A radio controlled toy vehicle that has the ability to transform from a compact (narrow wheel track) configuration to an expanded (wide wheel track) configuration. The toy vehicle includes at least one driving wheel. Left and right main transformation arms are attached to left and right chassis bodies. A transformation drive is adapted to cause the main transformation arms to move towards or away from each other when the transformation drive is actuated, thereby causing the left and right chassis bodies to move towards or away from each other.

Abstract: A padded face rest having a single cam lock, double pivoting adjustment mechanism. The adjustment mechanism includes a pair of cantilever members, each cantilever member being comprised of a pair of spaced apart, substantially parallel cantilever plates having locking members at each end. One of the locking members is adapted to lockingly engage a locking member attached to the padded face rest, and the other locking member is adapted to lockingly engage a locking member attached to the face rest attachment frame. A locking rod extends through the mid-portion of all of the cantilever plates. A cam clamp is attached to an end of the locking rod and, upon rotation, causes the plates of each cantilever member to be pulled towards each other to thereby lockingly engage adjacent locking members.

Abstract: Jigsaw puzzles for use by young children to practice elementary arithmetic. Each puzzle is circular and includes a center piece, four middle ring question pieces, and twelve outer ring answer pieces. One side of each puzzle contains the arithmetic question and answer pieces and the other side forms a picture when the question and answer pieces are put together correctly. A transparent tray is used for assembling the pieces of the puzzle. A transparent cover is adapted to be snapped into place over the tray and allow the container to be turned over to view the picture side to determine if the picture is either (1) correct, which means that all of the arithmetic questions have been answered correctly or (2) incorrect, which means that some or all of the arithmetic questions have not been answered correctly.

Abstract: A carrying case, such as a purse or fanny pack, having a skeleton formed of a bendable, rigid material. The skeleton has front and rear opposing sidewalls, each having an arcuate shape. The sidewalls are joined along the bottom longitudinal edges thereof and are normally spaced apart along their upper longitudinal edges to form a clamshell shaped configuration. The front sidewall has an inwardly and downwardly extending latching lip formed in its upper longitudinal edge. The upper longitudinal edges of the sidewalls can be closed and latched by squeezing the front and rear sidewalls toward each other and snapping the upper longitudinal edge of the rear sidewall into the lip formed in the upper longitudinal edge of the front sidewall. A fabric cover is pulled over and around the sidewalls of the skeleton. The endwalls of the fabric cover forms the endwalls of the carrying case.

Abstract: A precision guidance system for positioning motor vehicles on a motor vehicle support surface, such as a carrier for transportation. The guidance system includes primary guide members extending from the support surface, preferably located to engage the inner surfaces of the motor vehicle tires. The guidance system allows precisely positioning the motor vehicle on the support surface for purposes of engaging mating devices extending from the motor vehicle and the motor vehicle support surface, such mating devices including vehicle restraint means, electrical connections, and pneumatic or hydraulic connections.

Abstract: A modular shopping cart cushion comprised of a plurality of generally rectangular pads, including end pads and interior pads. Each pad is releasably attachable to each adjacent pad by flexible hinge members. The hinge members have a width adapted to allow the pads to be folded up accordion-style with adjacent planar surfaces being in abutment to form a compact package for transport and storage. The modular cushion has a width and length adapted to fit into the primary cargo area of a shopping cart.

Abstract: A body pouch band for carrying personal effects on the limb of a user. The body pouch band includes a pouch having front and rear walls and side, top and bottom edges. The side and bottom edges can be gusseted. The top of the pouch can be fastened shut by use of an interlocking groove type sealing mechanism. The pouch is attached to a limb band which can be fastened to the wrist, upper arm, or ankle of a user. The limb band is made of stretchable material, and can be a cuff or a sleeve. The cuff embodiments have stretchable straps or bands that are either releasably fastened together at their outer ends, such as by use of hook and loop fastener material, or permanently fastened at their outer ends, such as by sewing. The sleeve embodiments are made of stretchable material, and are adapted to be slid into position over the selected limb portion of the user. In the sleeve embodiment for use over the upper arm, opposing holes pass through the wall of the sleeve to provide improved flexibility.

Abstract: An impact tool for use in removing a non-threaded fastener from a first substrate anchored to a second substrate by the fastener. The tool includes a shank having a longitudinal axis, first and second ends, and an exterior surface. A driving head is located on one end of the shank and a fastener exposure/dimpling head located on the other end. The fastener exposure/dimpling head includes a fastener receiving cavity, a cutting lip extending outwardly from the fastener receiving cavity, and a dimpling section located between the cutting lip and the outer surface of the shank. The cutting lip is placed around the nailhead and the driving head tapped to expose the nailhead. The dimpling section creates a cavity in the surface of the first substrate which can subsequently be filled.

Abstract: A radio controlled toy vehicle having a single driving wheel. First and second chassis bodies are located on opposite sides of the driving wheel, and the driving wheel and chassis bodies rotatably attached to a primary axle. Support wheels are rotatably attached to the chassis bodies at a location distal to the point of attachment of the chassis bodies to the primary axle. First and second reversible electric motors are drivingly connected to the driving wheel by drive train means. A radio control receiver is attached to one of the chassis bodies, and is adapted to independently actuate the electric motors in a forward or reverse direction in response to control signals sent by a radio control transmitter. When both of the electric motors are operating in the forward or reverse direction, the driving wheel propels the vehicle in that direction.
