Abstract
An electrical control popout actuator mechanism preferably integrated with a trimmer potentiometer is vertically mounted directly to a printed circuit board. The electrical control popout actuator mechanism has a cam cylinder member, a spring biasing member, a shaft member, and a follower member which allow it to extend during use and retract when not in use. Flanges on said follower member follow cooperating cam paths to allow activation of the mechanism.
Claims18
An electrical control popout actuator mechanism for integration with a printed circuit board, comprising:
- a cam cylinder member, having a tubular body defining interior and exterior wall surfaces, one end of said cam cylinder member having a spring member seat and being perpendicularly mounted to said PCB, the other end of said cam cylinder member having at least one shaft member flange slot parallel to the axis of said tubular body, said interior wall surface having outer cam path slants and slots defining an outer cam path parallel with the axis of said tubular body;
- a shaft member having a cylindrical body having an exterior wall surface, and at least one shaft member flange, said shaft member positioned in said cam cylinder member and said shaft member flanges positioned in said corresponding shaft member flange slots, said shaft member flange extending away from said cylindrical body and through said tubular body of said cam cylinder member thereby integrating said cam cylinder member and said shaft member, said exterior wall surface of said shaft member forming an inner cam path with inner cam path slants at one end of said shaft member, said outer cam path and said inner cam path having a cam profile in the same direction parallel to the axis of said cam cylinder member;
- a follower member having a tubular body including at least one follower member flange, said follower member rotatably coupled to said shaft member and positioned in said cam cylinder member such that said follower member flange engages said outer cam path and said inner cam path;
- and
- a spring member mounted within said cam cylinder member and positioned between said spring member seat and said at least one shaft member flange for biasing said follower member flanges against said inner and outer cam paths.
A control system within a vehicle, said control system having a user adjustable function, said function controlled by an electrical control popout actuator mechanism integrated with a trimmer potentiometer, comprising:
- an electronic device located in said vehicle for providing a function;
- an electrical control popout actuator mechanism integrated with a PCB in said electronic device for adjusting said function, comprising:
- a cam cylinder member, having a tubular body defining interior and exterior wall surfaces, one end of said cam cylinder member having a spring member seat and being perpendicularly mounted to said PCB, the other end of said cam cylinder member having at least one shaft member flange slot parallel to the axis of said tubular body, said interior wall surface having outer cam path slants and slots thereby defining an outer cam path parallel to said cam cylinder member;
- a shaft member having a cylindrical body having an exterior wall surface and at least one shaft member flange, said shaft member positioned in said cam cylinder member and said shaft member flanges positioned in said corresponding shaft member flange slot, said shaft member flange extending away from said cylindrical body and through said tubular body of said cam cylinder member thereby integrating said cam cylinder member and said shaft member, said exterior wall surface of said shaft member forming an inner cam path with inner cam path slants at one end of said shaft member, said outer cam path and said inner cam path having a cam profile in the same direction parallel to the axis of said tubular body;
- a follower member having a tubular body including at least one follower member flange, said follower member rotatably coupled to said shaft member and positioned in said cam cylinder member such that said follower member flange engages said outer cam path and said inner cam path;
- and
- a coil spring member within said cam cylinder member and positioned between said spring member seat and said shaft member flange for biasing said follower member flanges against said inner and outer cam paths.
