Abstract
The movable actuating lever is connected to a transmission lever, at one hand, and is guided by means of a pin within a guideway in the housing of the apparatus, on the other hand. The transmission lever serves at the same time for transmitting the actuating motion via further levers to the apparatus part to be actuated. Due to the position and the shape of the guiding groove and the lever, the course of motion of the actuating lever with respect to the fixed handle portion may be optimally adapted to technical and ergonomic requirements in order to achieve an effective force transmission having minimal frictional losses. Furthermore, no levers are in the way, and injuries are avoided.
Claims10
An actuating device on an apparatus for manually operating at least one movable part of said apparatus comprising:
- an actuating lever with four gripping points corresponding to four fingers of a hand that actuates the device;
- a lever system connecting said actuating lever and said movable part;
- and
- a guideway for guiding a motion path of said actuating lever;
- wherein said lever system comprises a transmission lever pivotally connected to said actuating lever at a swiveling axis;
- and
- wherein said movable part is a thrust member for the delivery of a flowable medium.
An actuating device on an apparatus for manually operating at least one movable part of said apparatus comprising:
- an actuating lever with four gripping points corresponding to four fingers of a hand that actuates the device;
- a lever system connected to said actuating lever comprising two swivelling levers which hinge and guide said actuating lever;
- wherein one of said two swivelling levers is a transmission lever for connecting said actuating lever to said movable part;
- wherein a second swivelling lever is a guiding lever connected between the actuating lever and a housing of said apparatus;
- wherein at least one of said transmission lever and guiding lever is connected to the actuation lever at a position located within an upper half of said actuation lever facing said apparatus;
- and
- wherein said movable part is a thrust member for the delivery of a flowable medium.
