Abstract: A sensing-enabled automatically foldable scooter frame includes a support frame, a seat, an electric pushrod, a sensor, a controller, and an operating member. The electric pushrod is provided at the support frame to drive folding and unfolding of the support frame. The sensor is provided at a surface of the seat. The controller receives a signal from the sensor to control extension or retraction of the electric pushrod. The operating member is electrically connected to the controller. The operating member is disabled when the sensor detects existence of pressure, and the controller controls the electric pushrod in a retracted state, thereby ensuring the support frame in an unfolded state. The operating member is enabled when no pressure is detected, and the controller drives folding or unfolding of the support frame. The present invention can prevent a scooter frame from being folded accidentally, thereby protecting a user from being hurt.

Abstract: An apparatus facilitating the lifting and movement of objects. The present invention, in one embodiment, features a curved rim extending around a mounting plate to which an object or an object carrier can be attached. The object is mounted off-center relative to the central axis of the curved rim. According to the invention, a counter-balancing weight offsets the moment associated with the object to allow the moving device to roll along a surface, and thereby move the object, with application of a small amount of force. According to embodiments of the present invention, the curved rims include at least one section having an increased radius of curvature relative to other sections of the curved rim to promote rotation of the moving device.

Abstract: A vehicle has two suppoting wheels, each mounted on an axle. A carriage that can hold a human rider is positioned in between the supporting wheels, suspended from the axle. No portion of the carriage extends from the axles a distance greater than the radius of the supporting wheels. A driveable wheel, such as a sprocket gear, between the supporting wheels is mounted on an axle and moves with a supporting wheel. Turning the driveable wheel from the carriage causes the supporting wheel to turn. The supporting wheels can be connected at their peripheries so as to enclose the carriage. Alternatively, the supporting wheels can be unconnected and fixed to the axles so that they can rotate independently. The vehicle can be unpowered, powered by the rider, or powered by an engine. It can be adapted to ride on land, water, or snow and ice.

Abstract: An attachment for affixing hand operated side wheels to a scooter board is described. The attachment has a frame, preferably made from a metal strap with up-turned ends. The ends are sufficiently spaced to accommodate a scooter board placed between them. Each end has a short axle on which a wheel is mounted. The wheels have an outwardly oriented offset handle acting as a crank to propel the attachment when combined with a scooter board. A washer and bolt passing through the center hole of the scooter board is sufficient to mount the attachment. Slotted indexing blocks attached to the frame engage reinforcing ribs on the underside of the scooter board to prevent rotation of the attachment.

Abstract: A land transportation device for compact, sandy and open land, with or without a slope, based on the intersection of two reinforced and identical truncated rings in orthogonal planes with respect to each other. The geometric centers shifted of the rings are shifted over the line of intersection of these planes. The weight of the device is reduced since it is made up of two light truncated rings, while at the same time, the cabin space is increased. The rings present a soft friction surface which gives the device better adherence to the ground, reducing the vibrations and facilitating the movement of the device. The device also possesses a hinge system which makes it possible to fold the ring on two axes, parallel to each other, thereby reducing its size. The disassembled device can be placed in a rectangular box for transportation and storage.

Abstract: A parallel vehicle includes three main control systems. The first controls the position and angle of the two parallel wheels relative to a fixed chassis, enabling the wheels to be moved outwardly and inwardly and the camber varied for greater stability, aerodynamic effect, or turning. This first system may be mechanically or hydraulically actuated, but preferably is controlled by a pair of control members whose position relative to the chassis corresponds to the desired position of the wheels relative to the chassis in order to provide an intuitive control mechanism. The second system is the propulsion system which may, for example, take the form of a derailleur drive of the type used in bicycles, but with power from the propulsion system being transmitted to the wheels via a rotating cable and individual gearboxes for each wheel which permit the direction of the wheels to be reversed.

Abstract: A vehicle, especially an amusement vehicle, in which a frame having a seat adapted for seating two occupants is located within the radial confines of a pair of relatively large coaxial spaced wheels. The frame includes rollers mounted thereon and distributed circumferentially about the inwardly facing annular surfaces of the larger wheels and engaging the same so as to rotatably support the frame within the wheels. A pair of relatively large chains are mounted circumferentially on the respective wheels within the radial confines thereof concentrically with the common axis of the wheels and are driven by crank driven sprockets carried by the frame to thereby propel the vehicle. The center of gravity of the frame, including any occupant therein, is below the common axis of the wheels so that when the sprockets are driven, the frame will first move within the wheels to create an unbalanced condition in the vehicle and the wheels will then commence rotation thereby causing the vehicle to move.

Abstract: A vehicle, especially an amusement vehicle, in which a frame having seating means for receiving at least one occupant is located within the radial confines of a pair of relatively large coaxial spaced wheels. The frame includes rollers mounted thereon, distributed circumferentially about the insides of the larger wheels, and rollingly engaging the wheels. At least one of the rollers for each wheel is driven in rotation by a mechanism under the control of the vehicle occupant for propelling the vehicle. The center of gravity of the frame, including any occupant therein, is below the common axis of the wheels so that actuation of the drive rollers in rotation will cause the frame first to move within the wheels to create an unbalanced condition in the vehicle. The wheels will then commence rotation and the vehicle will move. The wheels can be driven at respective speeds for steering purposes.
