Abstract
A cable operating mechanism basically comprises a fixed member, a wire takeup member, a single position maintaining abutment and a positioning member. The wire takeup member is movably mounted with respect to the fixed member. The single position maintaining abutment movably mounted with the wire takeup member. The positioning member is pivotally mounted with respect to the fixed member. The positioning member has a plurality of positioning abutments configured to engage the single position maintaining abutment such that the wire takeup member is positioned in one of a plurality of predetermined wire positions.
Claims30
A cable operating mechanism comprising:
- a fixed member;
- a wire takeup member movably mounted relative to the fixed member,
- a single position maintaining abutment non-movably mounted directly on and directly fixed to the wire takeup member with no relative movement therebetween, the single position maintaining abutment and the wire takeup member moving together as a unit relative to the fixed member during a wire releasing operation;
- and
- a positioning member pivotally mounted relative to the fixed member, the positioning member having a plurality of positioning abutments that selectively engage the single position maintaining abutment to position the wire takeup member in one of a plurality of predetermined wire positions corresponding to rest positions of the wire takeup member.

A cable operating mechanism comprising:
- a fixed member;
- a wire takeup member pivotally mounted relative to the fixed member about a first pivot axis;
- a positioning member pivotally mounted relative to the fixed member about a second pivot axis that is offset from the first pivot axis, the positioning member including a plurality of positioning abutments that selectively engage the wire takeup member and selectively maintain the wire takeup member in one of a plurality of predetermined wire positions corresponding to the rest postions of the wire taken member;
- and
- a wire releasing member including a plurality of release abutments that selectively engage the positioning member and move the positioning member during a wire releasing operation of the wire releasing member, the wire releasing member engaging a same one of the positioning abutments in at least two of the predetermined wire positions of the wire takeup member.

A cable operating mechanism comprising:
- a fixed member;
- a wire takeup member pivotally mounted relative to the fixed member;
- a driven abutment fixed to the wire takeup member with no relative movement therebetween, the driven abutment and the wire takeup member moving together as a unit relative to the fixed member as the wire takeup member pivots relative to the fixed member;
- and
- a wire pulling member movably mounted relative to the fixed member and the wire takeup member, the wire pulling member including a plurality of drive abutments selectively engaging the driven abutment to drive the driven abutment, the wire pulling member moving the wire takeup member as the wire pulling member moves during the wire pulling operation of the wire pulling member.

A cable operating mechanism comprising:
- a fixed member;
- a wire takeup member pivotally mounted relative to the fixed member about a first pivot axis;
- a positioning member pivotally mounted relative to the fixed member about a second pivot axis that is offset from the first pivot axis, the positioning member including a plurality of positioning abutments that selectively engage the wire takeup member to selectively maintain the wire takeup member in one of a plurality of predetermined wire positions corresponding to rest positions of the wire takeup member;
- and
- a wire releasing member including a plurality of release abutments that selectively engage the positioning member to move the positioning member during a wire releasing operation of the wire releasing member, the wire releasing member engaging a same one of the positioning abutments in at least two of the predetermined wire positions of the wire takeup member,
- the positioning abutments of the positioning member being arranged along an arc in a stair configuration relative to the second pivot axis, each of the positioning abutments having a respective radial distance measured from the second pivot axis to a radially outermost point on each of the positioning abutments, to the second pivot axis, the respective radial distances of the positioning abutments all being different from each other.
