A snake feeding device comprises a base having opposite ends, an actuator pivotally mounted on the base, and first and second sets of drive rolls spaced apart in the direction between ends of the base. Each set includes a roll on the base and two rolls on the actuator for engaging a snake therebetween and displacing the snake relative to the base in the direction between the ends thereof in response to rotation of the snake. The actuator selectively displaces the rolls of each set relative to one another.

A rear view mirror assembly for a motor vehicle, includes a mirror holder (1) for supporting a mirror body, an operating threaded shaft (4) provided to be capable of moving backward and forward along an approximately axis thereof in a mirror case, and a nut member (7) connected with a driving device in the case. The holder (1) is supported to be capable of inclining around a lateral and/or a vertical incline center axes with respect to the case. The head (4b) of the shaft (4) is fitted in the fitting portion (1a) of the holder (1) to be capable of inclining to the fitting portion (1a). The screwed portion of the shaft (4) is screwed in the member (7). The member (7) has an annular projecting portion (7e) for sliding on a circumferential surface of the shaft (4). The specified portion of the shaft (4), which is positioned at the opposite side to the holder (1) and away from the screwed portion, is penetrated through a through hole (7f) formed by the projecting portion (7e) to be capable of moving backward and forward along the approximately axis of the shaft (4) and inclining therearound. By driving of the device, the member (7) is rotated so as to backward and forward move the shaft (4) along the approximately axis thereof to the case and then to incline the holder (1) to the case.

A system for reversibly rotating a shaft for operation of the control system in a covering for an architectural opening includes two relatively linearly moveable members at least one of which has a low friction component engaging a helical path on the other so that linear movement of the members causes relative rotation to drive the rotatable shaft of the control system.
摘要:
The invention is an exercise device which creates a controlled and infinitely variable resistance profile using a pair of rods that are wrapped about a common axis with a varying pitch. A slide unit is attached to the rods with rollers. When the slide unit is moved in a linear motion, the movement of the rollers on the rods causes the rod, and a shaft on which they are mounted to rotate. In one embodiment, the rotation of the shaft is used to move one or more units of a set of stacked weights. In a second embodiment, a rotation motion of the shaft on which the rods are mounted, causes a linear motion to the slide unit which is attached to a set of stacked weighs.

A displacement adjustment device (100) for at least partly converting a rotation into a translation, comprising: a rotation input member (114) which is bearing-mounted so as to be rotatable but axially secured relative to a frame said rotation input member (114) being provided with a hollow (116) extending axially therethrough; a bar (11) positioned in the hollow (116) and having its outside surface provided with a screw thread (17), means (12) being prvided for preventing rotation of said bar (11) relative to a frame; and a coupling gear wheel (120) arranged for rotation in the rotation input member (114), wherein the axis of rotation of the coupling gear wheel (120) is substantially perpendicular to the axis of rotation input member (114), wherein the coupling gear wheel (120) has teeth (121) engaging with the screw thread (17) of the bar (11) and, wherein the rotation bearing of the coupling gear wheel (120) comprises a slip coupling (130) relative to the rotation input member (114). An example of an application of such a device is in a mirror adjusting instrument of a vehicle.
