  • Patent number: 5975551
    Abstract: A foldable bicycle designed so when the bicycle is folded, the front and rear frames bypass each other (non-overlapping) to permit a complete folding position and using a fold on or near the seat tube, and to maintain a rigid open riding position with simple standard fold restraining devices.
    Type: Grant

  • Patent number: 5868404
    Abstract: The braking system for one or both of the skates such as in-line skates. The braking system uses a hand held RF transmitter activated by a switch to initiate braking action by a receiver located on the skate. The brake, once actuated, can work directly off the ground and be a friction pad type device on the skate and when activated it drags on the ground or a two-fold friction device composed of a extra back wheel that can be restrained by a pad braking device before it is then lowered to having a restricted roll friction on the ground. The braking device can work directly onto the rolling wheels with a friction pad or again it can be a twofold friction device composed of a small convex braking wheel above the rolling wheels that is slowed by a friction pad device before it is used then to restrict the rolling wheels. The remote radio signal device generates the radio signal which is tied to the braking function of the skate to provide either continuous force or a variable braking force.
