Device for connecting either one of two alternative operating members with an operated member

Claim 1

A device for connecting either one of two alternative operating means, each of which comprises an elongated operating member having axial operating movement, to a means intended for operation which also has an elongated, axially movable operated member, the operating members of the two operating means being each connected to an individual first and second swing arm, said swing arms being rotatable about a common axis line extending in a transverse direction to the direction of movement of the operating members; the operated member being connected to a third swing arm which is rotatable about said axis line and situated between the first and second swing arms; each of the first and second swing arms having coupling means arranged to connect the first and second swing arms to cooperating coupling means of the third swing arm in a non-rotatable manner during coupling move-ment parallel with said axis line; the first and second swing arms being immovable in the direction of the axis line while the third swing arm is movable back and forth in the direction of the axis line by means of manually operable moving means so as to be coupled to either one of the first and second swing arms in a predetermined relative rotation position between the third and the first or second swing arm, respectively, said third swing arm also being rotatable with the aid of said moving means, the first and second swing arms being rotatably and axially movably journalled on a shaft; the shaft being, in turn, rotatably and axially movably journalled in a frame; the third swing arm being rigidily connected to the shaft; the frame having guides which prevent movement of the first and second swing arms in the direction of the shaft; and the moving means being connected to the shaft for axial movement and rotation of the same.

Claim 2

A device for connecting either one of two alternative operating means, each of which comprises an elongated operating member having axial operating movement, to a means intended for operation which also has an elongated, axially movable operated member, the operating members of the two operating means being each connected to an individual first and second swing arm, said swing arms being rotatable about a common axis line extending in a transverse direction to the direction of movement of the operating members; the operated member being connected to a third swing arm which is rotatable about said axis line and situated between the first and second swing arms; each of the first and second swing arms having coupling means arranged to connect the first and second swing arms to cooperating coupling means of the third swing arm in a non-rotatable manner during coupling move-ment parallel with said axis line; the first and second swing arms being immovable in the direction of the axis line while the third swing arm is movable back and forth in the direction of the axis line by means of manually operable moving means so as to be coupled to either one of the first and second swing arms in a predetermined relative rotation position between the third and the first or second swing arm, respectively, said third swing arm also being rotatable with the aid of said moving means, the first and second swing arms being rotatably and axially movably journalled on a shaft; the shaft being, in turn, rotatably and axially movably journalled in a frame; the third swing arm being rigidily connected to the shaft; the frame having guides which prevent movement of the first and second swing arms in the direction of the shaft; and the moving means being connected to the shaft for axial movement and rotation of the same.
