Abstract: A flexible skateboard may include a pair of direction casters mounted for steering rotation on a twistable one piece skateboard with a multi-arm spring return assembly using pivoting stops associated with the wheel fork and non-pivoting stops mounted to the skateboard. Centering spring arrangements including range or rotation limitations such as hard stops are included. One or two dual wheel assemblies may be exchanged for the single wheel assemblies for ease or riding or learning how to ride. One piece skateboard bodies are formed by rigidly connecting together multiple pieces of the same or similar plastic molded parts to form a bridge like connecting member having increased structural strength for its weight.

Abstract: A scooter having a marking device that is movable from a first position, in which the marking device does not contact the surface on which the scooter is being operated, and a second position, in which the marking device contacts the surface on which the scooter is being operated. The scooter includes a scooter body which rotatably supports the marking assembly. The marking assembly includes a marking portion which creates markings on a riding surface when in frictional contact with the riding surface. The marking assembly also includes a foot actuation portion which is accessible to the user and allows the user to activate the marking assembly while riding. In one arrangement, the marking portion includes a removable cartridge with marking elements that create markings on the riding surface when in frictional contact with the riding surface.

Abstract: A marking device that is supported by a personal mobility vehicle, such as a scooter, is movable from a first position, in which the marking device does not contact the riding surface, and a second position, in which the marking device contacts the riding surface. The marking device includes an attachment portion and a marking portion that creates markings on the riding surface as a result of frictional contact with the riding surface. The marking device can also include an actuation portion which is accessible to the user and allows the user to move the marking device to the second position. In one arrangement, the marking device includes an elastic marking member which is configured to bend in order to maintain contact with the riding surface.

Abstract: A soft impact projectile launcher including a launching mechanism that creates a burst of air or air pressure in order to launch a projectile. The launching mechanism includes an outer cylinder and a spring-loaded piston configured to generate the burst of air. The projectile launcher may also include a projectile reservoir and a loading member that positions projectiles for launching. The projectile launcher can launch projectiles that are made from a superabsorbent polymer and consist of mostly water.

Abstract: This invention promotes quicker swing speed and or balance, by using aero dynamic, properties as you would use a dragsters, parachute to slow down, a moving car, without brakes, when you swing this training device it builds up your muscles, and helps your balance, without using weighted clubs, this mimics the golf swing, more natural, because it does not add weight to a club, head, therefore it is a better swing trainer, and just uses wind resistance, at the clubhead, to slow down your normal swing, therefore, increases, and builds the right muscles needed for better swing speed, as I said before, I can send pictures of my proto-type, if needed.

Abstract: A powered cycle vehicle having an adjustable mounting system for a power unit is described. A power unit is attached to a wheel mounting bracket which is affixed to the vehicle frame and carries the cycle wheel. The wheel mounting bracket may be a unitary structure that defines a wheel mount location and a power unit mount location. Adjustment of the power unit can be made independently of adjustment of the cycle wheel.

Abstract: A skateboard may include a pair of foot support boards connected by a torsion bar connecting element, a torsion bar cover tube mounted to the foot support boards and surrounding at least a portion of the torsion bar connecting element and an outer tube mounted for rotation around the torsion bar cover tube in response to contact with an obstacle. One or more bushings supporting the outer tube on the torsion bar cover for rotation. The skate board may include a tube mounted for rotation on a connecting element between the foot support areas. A method of skateboarding may include providing a skateboard having a longitudinal axis running between a pair of foot support areas and providing a tube mounted for rotation about the longitudinal axis between the foot support areas in response to contact with an obstacle.

Abstract: A flexible skateboard may include a pair of direction casters mounted for steering rotation on a twistable one piece skateboard. A center section may be made sufficiently narrower than outboard foot support areas so that the board may be twisted by a rider to add energy for rolling motion to wheels in the casters. The center section may also be made sufficiently resistant to bowing and twist so that the skateboard may be ridden as a conventional, non-flexible skateboard. Wells may be provided to resist twisting and provide gripping surfaces on the board for the rider's feet.
