HAND OPERATED LEVER

摘要

The hand-operated lever (1) is intended in particular for actuating a valve or the like in pipelines. The hand-operated lever can be locked in predetermined positions by means of a catch device which can be engaged and disengaged by an actuating device (4). According to the invention, the hand-operated lever has an outer movable lever part (2) which is conveniently made of plastic and is designed like a housing and in whose free end the actuating device is arranged. An inner lever part (7), which is preferably made of metal, is arranged in a smooth-running manner in the interior of the outer lever part (2). In the area of the head part of the lever, the inner lever part (7) is firmly connected to a device, such as an actuating shaft (14), actuating the valve or the like. The outer lever part (2) carries a catch element (5) which is movable with the outer lever part (2) and is formed by projections or teeth which interact with a corresponding fixed tooth part (16) while forming a catch device (6). An actuating detent (8) is mounted in a pivotable manner on the inner lever part, which actuating detent (8) is exposed on the underside of the outer lever part (2) and is pressed in the direction of the inner lever part (7) upon actuation (4), for which a nose (10) on the other end of the actuating detent (8) here carries the outer lever part (2) with it in order to disengage the catch elements (5) on the outer lever part (2) and release the catch device (6). After the actuating shaft (14) is adjusted, the actuating detent (8) is released and the outer lever part (2) returns automatically into its locking position in the catch device (6) so that the hand-operated lever (1) is fixed in this locking position. ……
