Claims
- 1. A resettable breakaway device, comprising:
- an inner member having a first end and a second end;
- an outer member having a proximal end and a distal end;
- said proximal end is pivotally attached to said second end of said inner member;
- a releasable engaging means attached to said inner member and in releasable engagement to said outer member for retaining said outer member substantially parallel to said inner member in a locked position; and
- wherein said releasable engaging means comprises:
- a lip portion having a first end and a second end, wherein said first end of said lip portion is attached to a side of said outer member adjacent said proximal end;
- a leverage means attached to said inner member; and
- an engaging member attached to said leverage means, wherein said leverage means applies a force upon said engaging member for retaining said engaging member in contact with said lip portion thereby retaining said outer member in said locked position.
- 2. The resettable breakaway device of claim 1, wherein said lip portion includes a substantially swaged face which is in engagement with said engaging member when in said locked position.
- 3. The resettable breakaway device of claim 2, wherein said engaging member is comprised of a roller rotatably attached to said leverage means.
- 4. The resettable breakaway device of claim 3, wherein said second end of said lip portion is below a center point of said roller.
- 5. The resettable breakaway device of claim 4, wherein said lip portion includes an arcuate shaped side opposite of said swaged face for allowing a user to easily reposition said outer member into said locked position.
- 6. The resettable breakaway device of claim 4, wherein said lip portion includes a ramped face opposite of said swaged face for allowing a user to easily reposition said outer member into said locked position.
- 7. The resettable breakaway device of claim 6, wherein said leverage means comprises:
- an arm pivotally attached to said inner member at one end and rotatably securing said roller at an opposite end thereof; and
- a spring means attached between said inner member and said arm, wherein said spring means applies said force to said arm toward said lip portion.
- 8. The resettable breakaway device of claim 7, wherein said spring means comprises:
- a shaft engaged at one end to said arm and slidably projecting through said inner member; and
- a compression spring attached to an end of said shaft opposite of said arm and in engagement with said inner member for applying said force upon said arm towards said inner member.
- 9. The resettable breakaway device of claim 8, wherein said force from said compression spring is adjustable by adjusting a position of a nut threadably fastened to said shaft.
- 10. The resettable breakaway device of claim 9, including a support member attached to said inner member and extending away therefrom for supporting said outer member when in said locked position.
