Abstract: A specially formed cylindrical disc, set in a fixed position, to be utilized on the PIC® inline skate to allow for jumps and spins in the sport of inline figure skating. The performance pick disc is made of molded rubber or synthetic material. The purpose of the performance pick is to provide enhanced spins, jumps, and footwork common in the sport of inline figure skating. The continuous curved shape of the performance pick discs outer edges provides a toe-in angle of between 0 and 22 degrees, the optimal angle being between 5 and 12 degrees for jumps and 0 to 5 degrees for spins. In a variation, the outer edges are slanted at an angle between 20 and 45 degrees on both sides continuously around the cylindrically formed disc to provide an optimal surface for push offs common in inline figure skating maneuvers.

Abstract: The present invention relates to a roller skate frame. The roller skate frame includes a plate being pressing molded into a main frame of the roller skate comprising two wheel-mounting plates corresponding to each other, and a front bottom connecting face and a shoe-mounting plate connecting thereto. The front bottom connecting face and the shoe-mounting plate are spaced apart with a suitable distance. Further, the front bottom connecting plate is formed by an upper and a lower bridging plate corresponding to each other, and both of which are positioned with a fastener hole respectively.

Abstract: An inline skate wheel assembly includes a loop that has a centrally disposed opening extending therethrough. The loop has an inner perimeter surface having a ring integrally attached thereto. A hub assembly includes a cylinder that has a first end and a second end. The first and second ends are open. A first perimeter flange is attached to an outer surface of the cylinder and abuts the first end. A second perimeter flange is attached to the outer surface of the cylinder and abuts the second end. The cylinder has a break therein so that a first portion and a second portion of the cylinder are defined. An axle may be extended through the cylinder when the first and second portions are extended into the loop and abutted against the ring so that the cylinder is rotatably mounted on the axle. The axle is secured to an inline skate track.

Abstract: The present invention relates to individual transport ways of conveyance, and includes changes in the design of the bottom part of the boot with a thickening sole, which consists the hidden installation into its the additional metal insole, fastened with the main shoe's insole, and the slit of a rectangular longitudinal aperture in the sole for the hidden installation in its the portable mechanical device with a stationary attachment to the boot without changing the appearance and form of the sole and the shoes.

Abstract: A skateboard for use on a hard surface, configured to simulate the response of a snowboard, has a support platform to which sets of wheels are mounted. The wheels have successively decreasing diameters mounted on a common axle. The wheels of successively decreasing diameter may additionally or alternately be formed of materials of successively greater frictional and compressibility characteristics.

Abstract: An all-terrain riding assembly comprised of a body member, including a supporting surface for feet of the user disposed between a front housing member having a rotatably mounted roller member and a rear housing member having a rotatably mounted, cylindrically-shaped roller member articulatedly mounted to the body member and including an assembly for controlling the rotational velocity of the rear roller member and thus linear velocity of the riding assembly.

Abstract: A skate including a boot having a toe portion and a heel portion and wherein a first skate frame is attached to the heel portion and a second skate frame is attached to the toe portion wherein the frames move independently of each other from flexural movement of the boot.

Abstract: These and other objects of the present invention are achieved by an all-terrain riding assembly comprised of a body member, including a supporting surface for feet of the user disposed between a front housing member having a rotatably mounted roller member and a rear housing member having a rotatably mounted, cylindrically-shaped roller member. A plane defining the supporting surface is below a plane defined by the top portions of the front and rear roller members. In a particular preferred embodiment the rear housing member is articularly mounted to the main body member.

Abstract: A sled which will allow the user to experience the joy of sledding when there is no snow on the ground. The sled has wheel racks which are attached to the bottom of the base of the sled, and a plurality of oval wheels are attached to the wheel rack, and the wheels extend from adjacent the front of the sled to adjacent the rear of the sled. The foremost wheels on the wheel rack are smaller that the remaining wheels to allow the sled to be used on grassy surfaces which do not have snow thereon. The smaller wheels will make it easier for the sled to roll on non-linear hills.
