A kit for forming such risers is also disclosed.

Abstract: A support (12, 28) is provided for a person to sit on the rocking device (10) to achieve a stable, but pleasing, motion. Front (18) and rear (20) leg pairs are provided for elevating the support (12, 28). Corresponding front (30) and rear (32) arcuate rocker members are provided for rotating on a surface. The rotating motion is converted to a rocking motion by eccentrically and rotatably mounting the legs (18, 20) outboard of the center of rotation of the rocker members (30, 32). Further rocking action is obtained by rotatably mounting the front (18) or rear (20) leg pairs to the support (12, 28). Rotation of the rocker members (30, 32) is synchronized by rotating tie rods (40) mounted along radials from the rotation centers for said rocker members (30, 32).

Abstract: A holder for breakable karate boards includes upper and lower spaced apart horizontal frame members secured to a vertical support for mounting the same on a wall. The free forward end of each frame member carries a track which faces the track of the other frame member for holding a karate board therebetween and in a vertical position. The width of the tracks are adjustable so that a plurality of boards can be held and each track is movable forwardly and rearwardly relative to the other so that the board or boards can be tilted either upwardly or downwardly. A bracket is provided for mounting the holder on a wall in any desired vertical position. The holder can also be removed from the bracket and mounted on various other pieces of equipment.

Abstract: A skipping rope handle is formed in two connected parts which are biased apart by a spring. The end of the skipping rope is attached to a button which is rotatable within an end of the handle parts. The handle parts can be held in closed condition by moving a ring axially over the rebated end of the handle part, when the handle has a generally conventional form and use. When released by the ring, the handle can be used for exercising the gripping muscles of the hand by forcing the parts towards one another against the bias provided by the spring.

Abstract: A device which effects the illusion of the levitation and animation of a source of light, supported by a non-reflective, resilient wire which under darkened conditions becomes imperceptible, carrying current to the light source from an attached circuit board/power supply which is in turn supported with the thumb by an attached flesh colored receptacle which when positioned properly, conceals the circuit board with the thumb.

Abstract: This swing, through a backward and forward motion by the user, serves to provide amusement and excellent exercise for children and adults. Primarily, it consists of a vertical frame, including a handle bar and a foot rest bar for its operation.

A vertically spaced apart upper and lower cross member extends outwardly equally from each side of the vertical member to receive the first pair of ropes which are secured to the lower cross member.

Abstract: A toy comprising a motor assembly mounted on an elevated support from which a toy aircraft is suspended by a flexible cable. The cable has a coiled wire sheath having one end connected to the support and the other to the aircraft. The cable hangs freely through a vertical passage in a bearing cup. A flexible shaft extends through the sheath from a driven connection from the motor to a driving connection with the propeller drive shaft. The drive shaft can be made up of a coiled spring encasing elastomeric cord serving to give it body and modify its resilience. The motor assembly may include an electric motor driven from a source of power through a speed control device and the speed of the assembly stepped up by a transmission of drive pulleys or gears. The aircraft is balanced by the way the flexible cable is connected to it and by downwardly and rearwardly angled tail wings to provide lift. When the propeller is actuated the aircraft describes orbits controlled by the cable operating in the bearing cup.
