Abstract:
A wheelchair having a pair of drivable wheels one of which is disposed on each side of a chair portion, a carriage slidably mounted to rotate about the rim of each wheel or another annular member coaxial therewith, a handle on each carriage grippable by a person using the wheelchair and manually actuable means on each carriage adapted to releasably engage the carriage with the annular member. The handles and the means adapted to releasably engage the annular members allow a user's propulsive force to be transmitted more easily and comfortably to the wheels and also allows for more certain braking of the wheelchair.
Abstract:
The present invention relates to a chair on wheels. Pushchairs for carrying infants and other chairs on wheels generally comprise four independent wheels supporting a carriage and/or frame. There exists a problem with pushchairs of this type, as they are not easily transportable across any terrain not presenting a flat and solid surface, such as a flight of stairs, or soft terrain such as mud or sand. The invention overcomes the problems by providing an improved wheeled vehicle, wherein the wheels are within an endless track which passes around them and engages with them so as to move along its length with their rotation. Braking mechanisms may be provided to assist a user pushing the chair down a flight of stairs.

Abstract:
A moveable load carrying assembly (10) including a chassis (12) having a first end (20) and a second end (40), there being provided one or more wheels (18) at or adjacent to the first end (20) of the chassis (12) and one or more wheels (16) at or adjacent to the second end (40) of the chassis (12). Each wheel (16, 18) is swivelable relative to the chassis (12) and braking means (35) are provided to act on at least one of the front wheel or wheels (18) in order to brake the front wheel or wheels (18). The braking means (35) is arranged to enable the front wheel or wheels (35) to be braked in any swivelled position relative to the chassis (12).A moveable load carrying assembly (10) including a chassis (12) having a first end (20) and a second end (40), there being provided one wheel (18) at or adjacent to the first end (20) of the chassis (12) and one or more wheels (16) at or adjacent to the second end (40) of the chassis (12). Each wheel (16, 18) is swivelable relative to the chassis (12) and means (50, 54) are provided to switch the front wheel (18) between a first steering mode in which the front wheel (18) is swivelable relative to the chassis (12), and a second steering mode in which the front wheel (18) is fixed in a straight-ahead direction relative to the chassis (12). The switch between steering modes occurs independently of the rear wheel or wheels (16).
Abstract:
A human-powered vehicle (100, 560) includes a structural frame (105) supported on multiple road wheels including driven wheels (110) each rotatable about an axle for propulsion, a seat (115) secured to the frame (105, 554) for supporting an operator, a hand crank (250) disposed above the driven wheel (110) and rotatable by hand by an operator seated in the seat (115), and a steerable rear wheel (120) operably linked to the seat (115) such that pivoting of the seat (115) about a seat pivot axis causes pivoting of the rear wheel (120) to steer the vehicle (100, 560).
Abstract:
An anti-theft vehicle system for a vehicle wheel having a rotational axis includes a linear actuator disposed within the vehicle wheel for operatively engaging and disengaging an interior surface of the vehicle wheel to resist and allow rotational movement of the vehicle wheel about the rotational axis. The anti-theft vehicle system further includes a receiver mounted within the vehicle wheel to receive a signal to activate the linear actuator.

Abstract:
An anti-theft vehicle system (10) for a vehicle wheel (12) having a rotational axis includes at least one inhibitor (24) disposed within the vehicle wheel to selectively engage and disengage the vehicle wheel to resist and allow rotational movement of the vehicle wheel about its rotational axis. The anti-theft vehicle system (10) also includes rotatable structure disposed within the vehicle wheel and cooperating with the at least one inhibitor for moving the at least one inhibitor between an engaged position and a disengaged position with respect to the vehicle wheel. The anti-theft vehicle system further includes a receiver (69) operatively associated with the vehicle wheel to receive a predetermined signal to activate the rotatable structure to move the at least one inhibitor between the engaged position and disengaged position.
Abstract:
Rollator-trolley assembly comprising a preferably continuously arranged bracket shaped handle at a rear upper side of the assembly, wherein the bracket shaped handle is pivotally adjustable between a rollator position, in which the bracket shaped handle is substantially directed to a front side, and a trolley position, in which the bracket shaped handle is substantially directed towards a rear side; wherein free walking space is provided between the wheels of the rollator-trolley assembly in the rollator position.
