Abstract
A cable operating mechanism is basically provided with a fixed member, a wire takeup member, a wire pulling member and a movement transmission member. The wire takeup member is movably mounted with respect to the fixed member about a first pivot axis to move between a plurality of predetermined wire positions. The wire takeup member includes a wire attachment part. The wire pulling member is movably mounted with respect to the fixed member. The movement transmission member is pivotally mounted with respect to the fixed member about a second pivot axis that is offset from the first pivot axis. The movement transmission member is operatively coupled to the wire pulling member and the wire takeup member such that a movement of the wire pulling member is transmitted to the wire takeup member via the movement transmission member.
Claims10
A cable operating mechanism comprising:
- a fixed member;
- a wire takeup member movably mounted with respect to the fixed member about a first pivot axis to move between a plurality of predetermined wire positions, the wire takeup member including a wire attachment part;
- a wire pulling member movably mounted with respect to the fixed member;
- and
- a movement transmission member movably mounted with respect to the fixed member about a second pivot axis that is offset from the first pivot axis, the movement transmission member being operatively coupled to the wire pulling member and the wire takeup member such that a movement of the wire pulling member is transmitted to the wire takeup member via the movement transmission member,
- the movement transmission member having a camming portion with first and second lateral sides, with only the first lateral side of the camming portion contacting the wire takeup member between each of the predetermined wire positions such that a triangle that is formed by the first pivot axis, the second pivot axis, and a point of contact between the wire takeup member and the movement transmission member, the triangle having an internal angle at the second pivot axis that is always obtuse throughout the predetermined wire positions.
