Abstract:
A bicycle transmission shifting device that includes a cable having a portion of the cable attached to a derailleur and also having another portion of the cable attached to a cable drum. Rotation of the cable drum in one direction pulls the cable to move the derailleur to move a bike chain in a first direction to change gears. Rotation of the cable drum in a second direction pulls or releases tension in the cable to move the derailleur to move the bike chain in a second direction to change gears.
Abstract:
The present invention provides an apparatus and methods directed to a selectively engageable shaft locking device. In one embodiment, a shaft lock device is presented which enables the testing of the shaft and shaft drive device without engaging the drive mechanism into a fully operational state. Another embodiment provides the ability to return the shaft lock device to a storage state after full engagement. The present invention also provides for methods of testing a selective shaft lock device according to the disclosures contained herein.

Abstract:
An adjustment device with a dual-guiding structure has two worm wheels respectively meshed with two coaxial worm rods (the worm wheel and worm shaft structure is an application of gear and threaded rod). Two worm rods are pivotally and longitudinally fixed by a driving shaft in line. An adjacent end of each worm rod has a locking recess to receive a locking head mounted on the driving shaft. Thereby, the locking head is selectively engaged with one corresponding locking recess to drive the corresponding worm rod when the locking head on the driving shaft moves in reciprocation. Then, one worm wheel engaged with the corresponding worm rod is rotated to make the wires on the work wheel to rewind or release.

Abstract:
The present invention relates to a haptic joystick system that is used with a computer system. The system according to the present invention includes the mechanism comprising the first link work and the second link work that respectively conduct 3 degree-of-freedom independently and are serially connected to each other. Therefore the said mechanism conducts 6 degree-of-freedom. The said mechanism is provided at its base plane with sensors and actuators, whereby not being affected by the inertia of the sensors and the actuators. Also, in the system according to the present invention, the first link work conducts 3 degree-of-freedom among the overall 6 degree-of-freedom that are frequently used in its application, and the second link work conducts another 3 degree-of-freedom. Thereby, the system according to the present invention can achieve the enhanced performance related to the energy effectiveness and the controllability.
Abstract:
A remote-controlled device for rotating tools, preferably medical tools, comprising a hollow body (1) which is embodied in the form of pivotally connected proximal and distal parts (2, 6) provided with a pair of adjacent end surfaces (5, 5′) which are angularly disposed with respect to the longitudinal axis of the body (1), and an axis (7) which is perpendicularly oriented with respect to the end surfaces (5, 5′) and provided with a central channel and a remote control mechanism. A shaft (10) arranged in the central channel of the device comprises driven, driving and transmitting sections (11, 12, 13) respectively, and operates as a link for transferring working rotational motion at a variable angle. The tilt angle between the distal part (6) and the longitudinal axis of the proximal part (2) can be equal to 180°.
Abstract:
The invention relates to an actuating device (1) for displacing a control device (3), which is subjected to the action of force counter to the direction of displacement (2). Said actuating device comprises an actuating element, which, inside a device housing (4), can be axially displaced in a direction of displacement by a turning spindle (5) of an advancing device (6). The turning spindle is connected in a rotationally fixed manner to a turning sleeve (8), which is rotatably mounted in the device housing (4) and which surrounds the turning spindle. Said turning sleeve is fixed, in relation to an annular flange (9) that is connected to the device housing in a rotationally fixed manner, counter to an advance turning direction (11) of the turning spindle by means of a spiral spring (10). An emergency disengagement device for resetting the actuating element counter to the direction of displacement is assigned to the spiral spring. The aim of the invention is to improve the actuating device by providing it with a compact and simple design and, at the same time, by enabling the winding of the spiral spring to be easily and precisely adjusted with regard to the torsional strength of the connection of the turning sleeve and the annular flange. To this end, the emergency disengagement device comprises a tension sleeve (13) for the spiral spring that is detachably held in a tensioning position. Said tension sleeve can be torsioned between a tensioning position and a final tensioning position and is subjected to the action of force toward its final tensioning position.
Abstract:
A forklift, in which, if a synchronous mode change-over switch is depressed, a forward/backward moving lever is switched over to the backward moving side, and a throttle pedal is stepped down, then a pusher is moved forward by a pusher cylinder in synchronization with the backward movement of the vehicle body of the forklift to thereby push out baggage carried on a fork therefrom. An oil pressure circuit connects together a pusher cylinder and an oil pressure pump. A hand-operated switch valve 21 is disposed in the oil pressure circuit. A valve full-open switch 22 opposes a projection portion 25 provided on and projected from a pusher lever 12 which is used to switch the state of the hand-operated switch valve 21. When the pusher lever 12 fully opens the hand-operated switch valve 21, the projection portion 25 contacts with the valve full-open switch 22 to thereby allow the valve full-open switch 22 to issue a detect signal to a control part of the forklift. Upon receiving the detect signal sent form the valve full-open switch 22, the control part operates a synchronous mode.
Abstract:
An operating device for inputting the coordinate positions of a controlled object that moves across a screen. The present invention is directed to obviating the problems of the prior art involving the bad operability of a knob which requires rotation through a large angle to move the controlled object across the screen, and the short life-span of the knob due to frequent use. In order to overcome these problems, the rotational number of a main shaft is increased by a rotational number increasing mechanism and the rotational number of the output shaft of the rotational number increasing mechanism is optically or magnetically detected. The present invention is therefore suitable for use as an operating device for a TV game machine.
