Abstract
An actuation device for use with a linearly actuated control element. The actuation device comprises a take-up body, a housing enclosing the take-up body, a shaft extending outwardly of the housing for rotating the take-up body, a flexible tension and compression element secured at one end thereof to the take-up body and a tube member extending outwardly of the housing and enclosing at least a part of the tension and compression element. The tension and compression element comprises a flexible guide strand and a plurality of elongated, rounded compression bodies wherein each compression body is threaded onto the flexible guide strand and positioned closely adjacent one another to form a tight packing.
Claims7
An actuation device for use with a linearly actuated control element, for example, a switching, regulating or steering element comprising:
- (a) a take-up body;
- (b) a housing enclosing said take-up body;
- (c) a shaft connected for rotating said take-up body, said shaft extending outwardly of said housing;
- (d) a flexible tension and compression element secured at one end thereof to said take-up body whereby said tension and compression element may be wound onto said take-up body or wound off of said take-up body, said tension and compression element comprising:
- (i) a flexible guide strand, and
- (ii) a plurality of elongated rounded pressure bodies, each pressure body having a longitudinal bore therethrough, each said longitudinal bore having a diameter which constantly increases smoothly from its longitudinal center to the ends of the bore for presenting a smoothly curved contact surface to said strand such that said strand contacts said bore along the entire length thereof when said tension and compression element is wound onto said take-up body, said pressure bodies being threaded onto said flexible guide strand and positioned closely adjacent one another to form a tight packing, and
- (e) a tube member, extending outwardly of said housing, said tube member enclosing at least a part of said tension and compression element during operation of said device, the other end of said tension and compression element adopted for operation of said linearly actuated control element in response to rotation of said shaft.
