Abstract
A manually controlled operating lever for a vehicle operator's platform has an electrical actuation transducer for transmitting control signals to a working function as a function of the pivoting of the lever and/or as a function of the actuation of at least one actuation element arranged on the lever. In order to avoid an undesired release of working functions, a manually operated activating element is mounted near a hand grip of the lever, and is coupled to a switching element which operates to activate the actuation transducer for the transmission of control signals as a function of actuation of the activating element.
Claims15
A manually controlled operating lever for a vehicle, the lever having a transducer for generating control signals for a working function in response to pivoting of the lever, and having an operating member arranged on the lever, characterized by:
- the lever having a hand grip;
- a manually operated activating element pivotally mounted near the hand grip;
- and
- a switching element operatively coupled to the activating element, the switching element generating control signals in response to actuation of the activating element, the activating element having a generally L-shaped cross section, and comprising a first leg coupled to the lever and a second leg extending from the first leg to a free end, said free end being near the hand grip when the activating element is not actuated, the second lea being forced away from the hand grip when an operator's hand is inserted between the hand grip and the activating element.
A manually controlled operating lever for a vehicle, the lever having a transducer for generating control signals for a working function in response to pivoting of the lever, and having an operating member arranged on the lever, characterized by:
- the lever having a hand grip;
- a manually operated activating element pivotally mounted near the hand grip;
- and
- a switching element operatively coupled to the activating element, the switching element generating control signals in response to actuation of the activating element;
- and
- an electrical control unit which receives and evaluates signals from the transducer and the switching element, and which responds to the pivoting of the lever, the control unit activating the transducer only if the lever is in a neutral position and the activating element is actuated.
