Abstract:
The present invention provides a propulsion assembly for a bicycle. The propulsion assembly includes a support member that at least extends from the bicycle frame to a distal end spaced-apart from the rear wheel. The assembly includes a first drive mechanism rotatably mounted on the frame and axially connected to the rear wheel for transmitting motion thereto. A second drive mechanism is rotatably mounted at the distal end of the support member and coupled with the first drive mechanism. Ratchet mechanisms axially extend from the second drive mechanism and connect to a pair of elongate members having pedals. The pedals are movable from an upper position to a lower position for transmitting one-way rotational power to the second drive mechanism. There is a means for selectively returning the pair of elongate members from the lower position to the upper position.
Abstract:
A drive apparatus for converting a substantially linear driving force to a rotary propulsive force, the apparatus including a power assembly for accepting a substantially linear drive force and converting said substantially linear drive force to a rotary propulsive force.
Abstract:
A skateboard deck is formed of several layers pressed and bonded together. Apertures are formed through the bottom-most layers, and impact support members are arranged within the apertures. The impact support members are more rigid than the other portions of the skateboard deck, and provide localized impact support while allowing the remaining layers of the deck to retain their performance characteristics and feel while strengthening the most vulnerable areas of the deck.
Abstract:
The present invention solves many of the problems for the wheelchair bound individual who wants an ergonomically sensible, convenient, yet powerful and stable wheelchair. The Trike's unique power source is provided by a rowing-type motion of the user rather than the less efficient "hand rim" grip or wrist propulsion. The rowing motion significantly reduces the chances for repetitive stress injuries, like carpal tunnel. Furthermore, the rowing motion and movements, are designed to facilitate efficient propulsion and steering in combination, to be effected simultaneously. The rowing motion allows the user's full arm strength and full range of motion to assist in the powering of the vehicle. The wheelchair also has a retractable fifth or propulsion wheel that allows the chair to be used in a confined space without sacrificing performance.
Abstract:
This invention relates to a kneel ing walker comprising a frame; a steering assembly coupled to a frame of the kneeling walker and having a steer ing stem and a control assembly; and a handle assembly coupled to the steering stem.
Abstract:
A cambering vehicle (10) including a forward column (14), a pair of trailing arms (16, 18) and a cambering joint (206) connecting the forward column (14) and the trailing arms (16, 18). The cambering vehicle (10) includes handlebars (64) configured to flex during use. Additionally, the cambering joint (206) includes a cover (290). Footboards (80, 82) supported by the trailing arms (16, 18) are angled to provide for comfort. Optionally, footboard assemblies (80, 82) supported by the trailing arms (16, 18) can include raised rear portions.
Abstract:
An occupant propelled device having at least one hydraulic cylinder, a platform and a housing. The at least one hydraulic cylinder has at least two chambers in fluid communication. The platform is attachable to the at least one hydraulic cylinder, such that upon movement of the platform a hydraulic fluid is displaced from one chamber to the other chamber. The housing is attachable to the platform at a pivot point and has at least one axle adapted to receive at least one wheel.
Abstract:
A skateboards (Figure 1A) that incorporate a curved board with removable wheel trucks and a cross member (52) that may be positioned in either a curved upward (Figure 2) or curved downward (Figure 1A) orientation. The removable trucks may be replaced with alternative trucks such as roller blade trucks (Figure 3B) or ice blade trucks (Figure 3C). Also disclosed is safety clothing (Figure 10) suitable for use when skateboarding.
Abstract:
A riding device includes a deck (12) upon which a rider can be supported. Front and rear (40) road wheels provide independent steering upon tilting or banking of the deck (12) in use. A steering column (18) is connected to the front wheels to provide additional steering control. The steering column (18) tilts in unison with the deck (12) and provides no steering effect upon deck (12) pivoting alone.
