A parallel mechanism for manipulating an object in space is provided. The parallel mechanism includes an end platform for supporting an object to be manipulated and an intermediate platform arranged in spaced relation from the end platform and connected to the end platform by a connecting element. A plurality of first links are connected to the end platform and a plurality of second links are connected to the intermediate platform. A linear motor is associated with each first link and each second link for translating the ends of the first and second links to move the end and intermediate platforms.

A retrofit for a thumb-lever throttle vehicle includes a rotatable handgrip which can be sleeved over a handlebar of a vehicle and a lever shoe which engages a thumb-lever throttle. Also included is an elongated coupler which couples between said handgrip and said lever shoe, such that said handgrip manipulates the thumb-lever throttle to control a fuel supply to an engine of the vehicle.

The nullHandi-Drivernull provides at least three functions at the steering column, this allows a disabled person, to operate and drive an automobile with an automatic transmission, by using one hand controll. An automobile with a standard transmission can be operated and driven, by using two hand controlls. A business such as a restaurant that offers food to patrons, parking, access, restrooms and ramps are nessasary for handicapped patrons to participate. A business that offers other activites for patrons, such as a Family Fun Center with concession go-karting, does not have go-karts availible for handicapped patrons, by modifing a concession go-kart with thenullHandi-Drivernull, a disabled person can operate and drive a go-kart by hand.

A bicycle control device is disclosed having a control lever that is operable in a first direction to operate the brake control mechanism, a second direction to operate the shift control mechanism in the winding direction and a third direction to operate the shift control mechanism in the release direction. In a preferred embodiment of the invention, when viewed from the perspective of a rider on the bicycle, the first direction is the direction of movement of the lever toward the handlebar. The second direction is the direction of movement of the control lever downward and the third direction is the direction of movement of the control lever upward. In a more preferred embodiment, the second and third directions are perpendicular to the first direction.

Combined gear change and brake control unit for a bicycle comprising, a support body (12) which can be fastened to the handlebar of the bicycle, a brake control lever (14) pivotally mounted on the support body (12) around a first axis (16), a gear change control unit (18) carried by the support body (12), comprising a shaft (20) turning around a second axis (22), either orthogonal or substantially orthogonal to said first axis (16), in which the shaft (20) carries a pulley (24) on which an end portion of a control cable of a derailleur is destined to be wound, and in which said shaft (20) is subject to a return torque tending to turn the shaft towards a direction (28) in which the cable is released, a gear change lever (30) arranged behind the brake control lever (14) for controlling the rotation of said shaft (20) in a direction of most winding of the cable (26) and a button lever (32) arranged on a side of said support body (12) for controlling the rotation of said shaft (20) in the release direction of the cable (28). The gear change control unit comprises a ratchet mechanism (36, 42) controlled by said button lever (32) and subject to assuming a home position and an active position. The ratchet mechanism (36, 42) is arranged so to leave the shaft (20) free to turn by a predetermined amplitude in the release direction of the cable (28), under the action of said return torque following each variation of position of the ratchet mechanism (36, 42) between the home position and the active position, and vice versa.

An alignment apparatus moves an X-Y slider together with X and Y beams. Electromagnetic guides (electromagnetic mechanisms) are interposed between the X-Y slider, the X beam, and the Y beam. The electromagnetic guides include alignment and acceleration electromagnets attached to the X-Y slider, and targets attached to the X and Y beams. The alignment electromagnet is feedback-controlled, whereas the acceleration electromagnet is feedforward-controlled.

The present invention relates to a driving school vehicle, a double pedal device with hydraulic coupling, a pedal box, actuators, and an instructor's post for use in the driving school vehicle. In particular, the hydraulic double pedal device for a driving school vehicle has at least one pedal on the driver's side, at least one pedal on the (99, 98, 97) on the passenger's side, and a hydraulic unit which couples the driver's side pedal with the passenger's side pedal in such a way that on operating the passenger's side pedal the driver's side pedal is also operated whereby the hydraulic device comprises at least one driver's side master cylinder arrangement, coupled to the driver's side pedal and at least one passenger's side master cylinder arrangement coupled to the passenger's side pedal and it is arranged symmetrically about an axis of symmetry (F), further comprising at least one pressure line (92) hydraulically connecting the driver's side master cylinder arrangement with the passenger's side mater cylinder arrangement, whereby a slider (63) mechanically coupled to the passenger's side pedal (99) and the passenger's side master cylinder arrangement (69, 70) to transfer force between the passenger's side pedal (99) and the passenger's side mater cylinder arrangement (69, 70), and a guide (65, 66) for it are provided.

A device for locking a brake pedal of a motor vehicle includes a cylinder and a piston mounted for reciprocating movement relative to each other. A spring is positioned within the cylinder so as to urge the piston away from a retracted position and towards an extended position. The external end of the piston is adapted to engage an exposed surface of a motor vehicle's brake pedal, containing an antifriction member such as a toothed tip integrally formed therewith or a separate rubber cap attached thereto. The cylinder further includes a hook member or some other mechanism adapted to engage a front surface of a motor vehicle's driver seat. The position of the hook member on the cylinder is adjustable so as to accommodate varying distances between the brake pedal and the driver seat.

The invention relates to a lift/swivel drive comprising a working element (2) which can traverse rotationally and linearly in relation to a housing element (1). In order to displace the working element in a controllable linear and rotative manner in relation to the housing element (1), at least one linear motor (5) and at least one rotative motor (7) are assigned to the working element (2) and/or the housing element (1).
摘要:
A throttle adapted for use on recreational vehicles, especially personal watercraft such as jet skies. The throttle is mounted on a handlebar of a jet ski preferably adjacent the engine on/off switch. The throttle is provided with a quick-release mechanism. Actuation of the mechanism permits the throttle to be moved from a thumb-activated position to a fingers-operated position. Deactivation of the mechanism will lock the throttle to the handlebar in either of the aforementioned positions.
