Abstract: The device for crossing obstacles for a motorized vehicle includes a chassis connected to n (n?3) wheels on each side, and a driver suitable for rotating the wheels. Each side of the chassis includes a mechanism comprising n?1 arms hingedly connected two-by-two about a shared pivoting axis on which the n wheels are distributed, respectively a front wheel, n?2 intermediate wheels, and a rear wheel. The mechanism allows each wheel to pivot relative to the axis of each adjacent wheel.

Abstract: A bicycle wheel hub assembly having a number of light emitting diodes (LED's) that are powered by rotation of the wheel during use of the bicycle. The hub assembly includes a magnet and a coil that are both internal to the hub. The light emitting diodes are powered by current induced in the coil and controlled so as to preferably prevent illumination of discrete LED's when the respective LED's are directed toward a user during rotation of the hub. The LED's are supported by the hub and rotate with the hub during rotation of the wheel. In some embodiments, the LED's are attached to the hub at locations that are both laterally inboard and laterally outboard relative to a spoke flange of the hub assembly.

Abstract: A wheelchair gym having a support bar releasably connected to the frame of the wheelchair. A vertical post is attached to the support bar and hand grips are slidably mounted on the vertical post. The hand grips are resiliently biased and may be moved conjointly or opposite to one another to provide arm exercise for a patient in the wheelchair. The gym also has leg supports on which resiliently biased foot rests may be moved conjointly or opposite to one another. The leg supports may be moved up and down or may be splayed laterally.

Abstract: A riding toy, free from maintenance work like battery replacement and able to urge a rider to take exercise while preventing the rider from getting tired thereof, has one front wheel and two rear wheels that are provided rotatably on a body, a generating motor linked with the rear wheels via a power transmission mechanism, a rectifier bridge circuit rectifying an output current from the generating motor, a storage unit storing a direct current from the rectifier bridge circuit, button switches of a button group on the body or a handlebar, an output unit on the handlebar including a sound emitting device or a light emitting device and a control unit causing the light emitting device or the sound emitting device of the output unit to perform a predetermined operation in response to operation of the button switches based on a current supplied from the storage unit.

Abstract: A sound generating apparatus includes a substantially U-shaped member having first and second panels, inner surface and outer surfaces. An arcuate section can be positioned on the inner surface of the U-shaped member for receiving and frictionally engaging a part of a bicycle fork. Two hollow ear sections can be positioned on the outer surface of the U-shaped member, each of the ear sections having an outer side and an inner side whereby exerting pressure on the outer sides of the ear sections widens an opening defined by the arcuate section to receive the bicycle fork part, and releasing the pressure on the ear sections allows the arcuate section to tighten around the bicycle fork part and frictionally engage the bicycle fork part. The arcuate section can define an arc of about 220 degrees.

Abstract: The vehicle, for example a stand-up wheelchair, comprises a frame (11) and, arranged on the latter, a seat device (19). On each side of the frame (11), the central wheel (13), which can be driven by a motor (27), and the front wheel (15) are operatively connected to each other by an endless chain (45). The frame (11) has a front part (21) and a rear part (23), which are connected to each other in an articulated manner by way of a joint (25). In the sitting position, the front wheels (15) are not in contact with the ground, which means that they do not obstruct the manoeuvring of the vehicle in a confined space. In the standing position, the front wheels (15) are in contact with the ground, but the central wheels (13) are not. The user, in the standing position, is thus able to turn about the axis of the vehicle, without the central wheels (13) having a blocking action.

Abstract: A foldable wheeled vehicle for individuals includes a main body, front and rear wheels joined on the body, and an anti-tip wheel joined on a rear end of the main vehicle body; the rear wheels will be in an immobilized state when the vehicle isn't in-use; the anti-tilting wheel will move to be below the rear wheels automatically when the vehicle is folded; thus, the vehicle in the folded position can be dragged with the front wheels and the anti-tip wheel contacting the ground; secondly, the anti-tip wheel will be in a higher position than the rear wheels when the vehicle is in an expanded in-use position; thus, when the vehicle is moving along a slope and tilting rearwards, the anti-tip wheel will contact the ground to prevent the vehicle from tilting rearwards excessively to overturn.

Abstract: The present invention provides a modular lateral transfer assembly (MLTA) adaptable to a wheelchair for easily transferring a wheelchair bound person, and a modular wheel assembly (MWA) adaptable to a wheelchair for easily transferring a wheelchair bound person laterally. The present invention also provides a wheelchair integrating the MLTA and MWA either individually or in combination.

Abstract: A manually-powered wheelchair that includes one or more features that enhance the overall maneuverability and stability of the wheelchair, such as centrally mounted drive-wheels and an anti-tip system. Other embodiments may include at least one of an adjustable anti-tip system that may be selectively located to several locations on the frame; a positive stop device attached to either the mounting bracket, frame, or the anti-tip system for limiting movement of the anti-tip system and the frame relative to each other; a resistance device attached to the frame and the anti-tip system for increasing resistance between the frame and the anti-tip system when the user leans backwards in the wheelchair; a wheel lock system engaging at least one of the drive wheels below the wheel's axis of rotation; and a tilt prevention device for selectively preventing any rotation of the wheelchair frame and anti-tip system relative to each other.
