Abstract: A system having a motor operatively connected to a steering system for reducing the steering effect is provided with a steering torque sensor for detecting steering torque in the steering system during a steering operation, an alternator output level sensor for detecting the output level of an engine driven alternator, and an ignition key switch sensor. In response to the output signal of the steering torque sensor, an assist signal is provided. In response to the output level of the alternator output level sensor and the position of the ignition key switch, an engine stall condition is detected. When engine stall occurs, the output torque of the motor is controlled in response to the assist signal for a predetermined period.

Abstract: An auxiliary seat for bicycles of elongated, generally cylindrical shape and having a slot running lengthwise of the seat body. The slot opens at its lower end through the material of the body and has a closed upper end, within the interior of the seat body. The auxiliary seat is mounted on the horizontal bar of a bicycle by simply slipping the slot over the bar until the closed upper end of the slot is brought into firm, embracing engagement with the bicycle bar. No special tools, brackets, or hardware are required for installation or removal of the auxiliary seat. The seat is mounted on the horizontal bar of a bicycle, forwardly of the main seat for secure and safe support of a passenger, such as a child.

Abstract: A seating device which is shown embodied in a hobby horse is easily changeable between a normal rocker configuration and a normal vehicular configuration. The device has a seat, a base with runners, a lock pedestal and a swivel pedestal connecting the seat to the base, and a lock mechanism to lock the seat to the pedestals in either of the configurations. The runners have wheels on one side and rocker surfaces on a second side. A method of changing the configuration is also provided.

Abstract: An air intake structure for a motorcycle includes a pair of hollow laterally spaced frames extending from a headpipe to a rear portion of the motorcycle, a hollow cross member connecting the frames together at an intermediate portion thereof, wherein the hollow interior of the cross member communicates with the hollow interiors of the frames. Intake openings are provided at a front portion of the frames for feeding air into the frames, while an exhaust opening is formed on the bottom of the cross member for exhausting air downward to the engine air intakes. A fuel tank cover is provided to cover a flexible fuel tank disposed between the laterally spaced hollow frames. The fuel tank cover includes a hollow fairing stay formed integrally therewith for supporting a motorcycle fairing, wherein the hollow fairing stay forms an air duct for directing air from an air inlet in the fairing to the intake openings of the frame.

Abstract: A cycle frame having a generally hollow unitary component of composite material connecting at least two support members. The frame component includes at least one pressure molded juncture comprising overlapping layers of resin impregnated fibrous material provided by overlapped parts of at least two adjacent wall sections.

Abstract: A trigger activated device for adjusting the inclination of a back frame of a wheelchair including a pair of adjusting assemblies provided on each of two sides of the back frame. Each adjusting assembly includes a horizontally disposed support which is fixed to a rear portion of a seat frame of the wheelchair. A back member is pivotally attached to the support. A threaded bar is pivotally attached to the back frame. A handgrip is attached to an upper portion of the back member. A trigger device disposed under the handgrip. A T-shaped hollow tube having a lug formed at one end thereof includes a first section and a second section protruding from a middle portion of the first section. The T-shaped hollow tube is pivotally mounted on a free end of the support via the lug. The threaded bar passes through the first section of the T-shaped hollow tube. An end cap is provided at a free end of the second section of the T-shaped hollow tube.

Abstract: Apparatus for use on standard or customized wheelchairs for providing means by which the wheelchair and occupant may be moved up or down a stairway or curb with a minimum of inconvenience to the occupant of the chair and to the handler of the chair. The apparatus having a pair of mounting brackets attached to the side frame of the chair with a tread assembly adjustably positioned thereon at a select angle to the mounting brackets. The tread assembly having a series of rollers over which a tread is placed so that the tread will interact with the stairsteps or curb to allow the wheelchair to glide up or down the stairsteps or curb without experiencing the bumps commonly associated with rolling a wheelchair up or down a set of stairs or curb. The apparatus has a brake assembly and extension handlebars allowing the operator of the chair to control the chair and the speed upon which the chair ascends or descends the stairs. The apparatus is removable from the chair when not in use.

Abstract: Steering mechanism for trailer wheels is provided with a slide having a tongue selectively engaged with and retracted from the fifth wheel of a tractor. When the tongue is engaged with the fifth wheel, any pivoting of the fifth wheel about the kingpin connection between the tractor and trailer, as when the tractor is steered from a straight ahead position relative to the trailer, causes the tongue to swing a link pivoted on the slide mechanism under the trailer. This swinging of the link drives a flexible cable to control a valve of a power steering system for the trailer rear wheels. The components are mounted under the floor of the trailer and a cable driven winch with a crank or power drive at the side of the trailer advances and retracts the slide to move the tongue into and out of engagement with the tractor fifth wheel. Magnets are mounted in the tongue and a torsion spring is provided in the winch mechanism to maintain tight contact between the tongue and fifth wheel.
