Abstract
A quick install positive lock pin for locking a plurality of objects together includes a handle portion which is in communication with a handle housing. The handle housing has an interior cavity within which a shaft member is disposed. The pin also includes a pair of retention mechanisms located in the handle portion that are moveable between a locked position where the mechanism extends outwardly of a slot formed in the handle housing and an unlocked position where the mechanisms extend no further than the outer edge of the opening. The retention mechanisms include a pair of plates that rotate upon reciprocal movement of the shaft member to move the retention mechanisms between the locked position and the unlocked position.
Claims20
A positive lock pin for locking a plurality of objects together, comprising:
- a handle portion;
- a handle housing in communication with said handle portion;
- a shaft member located within said handle housing and reciprocally moveable therewithin;
- and
- pair of retention mechanisms disposed within said handle housing and rotatably attached to said shaft member, to move said pair of retention mechanisms between a locked position where an outermost point of each of said pair of retention mechanism extends outwardly from a slot and an unlocked position wherein said outermost point of each of said retention mechanism does not extend outwardly from said slot.
A quick install positive lock pin for locking a plurality of object together, comprising:
- a handle portion in communication with a generally downwardly extending handle housing;
- a shaft member disposed within a cavity formed in said handle housing;
- and
- a pair of retention mechanisms disposed within said handle housing, each of said retention mechanisms in communication with a respective slot formed in said handle housing to move between a locked position and an unlocked position by linear movement of said shaft member, each of said retention mechanism being at least partially disposed within a pocket formed in a lower end of said shaft member and rotatably secured to said lower end.
A method of moving a quick install positive lock pin between a locked position and an unlocked position, comprising:
- providing a handle portion with a handle housing extending generally perpendicular therefrom;
- locating a shaft member within at least said handle housing;
- placing a pair of retention mechanisms in said handle housing and in rotatable communication with said shaft member;
- and
- moving said shaft member linearly to depress a spring, which allows said pair of retention mechanisms to rotate into and out of engagement with an associated slot formed in the handle housing, which thereby moves the pin between the locked position and the unlocked position.
