The present invention has an object of providing a toothed cable 1 not to cause an unnecessary load on a motor or the like, not to cause tear in the cover layer and to have excellent durability. The present invention provides a toothed cable 1 comprising a core cable 2, and a tooth line 3 helically wound on the outer periphery of the core cable 2. The toothed cable 1 further comprises a cover layer 4 covering the outer surface of the core cable 2 and the tooth line 3 with a resin continuously. This toothed cable 1 has helical convex portions 41 formed by covering the tooth line 3 with the resin and helical concave portions 42 formed by covering intervals in the tooth line with the resin, and the covered layer 4 is in contact with the core cable 2 and the tooth line 3.

A hydraulic apparatus for the operation of an elevator comprises a linearly extending hydraulic cylinder and a piston slidable therein. The piston has on its downstream side a plurality of pivotally interconnected thrust members the last one of which has a slide member which is provided with a support arm with which the slide member passes through a longitudinal slot in the jacket of a linear cylinder extending in a direction parallel to the path of motion of a load receiving device and to which the load receiving device is attached. The linearly extending hydraulic cylinder and the linear cylinder are open at the lower ends and the thrust members depend downwardly at the two cylinders. The thrust members have a continuous toothing and a gear supported rotatably between the two cylinders passes through longitudinal slots in the jackets of the two cylinders and engages with the toothing.

A drive device includes a drum housing rotatably supports a drum, allows an outer tube end to be inserted into an outer tube connecting portion and allows a wire to pass through a wire passage portion, and a drive member rotates the drum. An anti-deflection portion limits deflection of the wire and is formed on the drum housing/drive member. The anti-deflection portion includes a range surrounded by a line connecting one end of the formation range of the spiral groove and one end of the formation range of the insertion hole at the outer tube end connected to the outer tube connecting portion and a line connecting the other end of the spiral groove formation range and the other end of the insertion hole formation range at the end of the outer tube connected to the outer tube connecting portion, in the rotational axis direction of the drum.

A force transfer assembly that can transfer force at various angles and through relatively small bend radii includes a roller chain constrained in a raceway channel. The configuration provides multi-dimensional support so that a roller chain assembly, typically constrained to tensile loading, may also be used for compressive loading. A method for transmitting force along a non-linear path includes configuring a raceway channel having an upper raceway surface and a lower raceway surface, securing a chain assembly into the raceway channel between the upper raceway surface and the lower raceway surface with at least one lateral securing mechanism, and applying a tensile or compressive force to one end of the chain assembly in order to have the chain assembly transfer the tensile or compressive force to the other end of the chain assembly.

A drive apparatus includes a commutator motor having a hollow rotation shaft with an internally threaded section provided therein and a flexible power transmission cable inserted through the hollow rotation shaft such that a spiral thread-like rib of the cable engages with the internally threaded section of the hollow rotation shaft, whereby a propulsive force is transmitted to the cable to allow a window glass to be moved in a reciprocating motion. A guide roller with an intermediate section of the cable wrapped therearound is rotatably supported on a guide base to allow the passage of the cable. A curved guide section is provided relative to the guide roller to define a curved cable passage channel in a manner to cover a wrapped cable portion. The guide roller is rotated by the commutator motor through the cable, while the intermediate portion of the cable is pressed onto the guide roller.

The device has a drum constituted by a disc in one of the sides of which is formed a generally spiral-shaped groove. A cable retaining cap in the form of a fixed plate is placed against this side of the disc. When winding or unwinding the cable, the latter bears essentially against the lateral walls of the groove and substantially avoids rubbing against the cap. This results in high efficiency of the device and enables the device to be employed in automobile window-raisers.
