Abstract
A stabilizer arm lock including a frame member, a stabilizer arm having a first end pivotally attached to the frame, a locking pin operable to slidably move within the stabilizer arm, a cam surface on the frame member, and a biasing member operable to bias the locking pin into engagement with the cam surface.
Claims20
A stabilizer arm lock, comprising:
- a frame;
- a stabilizer arm having a first end pivotally attached to the frame;
- a locking pin operable to slidably move within the stabilizer arm;
- a cam surface on the frame;
- and
- a biasing member operable to bias the locking pin into engagement with the cam surface.
A method of operating a stabilizer arm having a stabilizer arm lock, the stabilizer arm lock comprising a frame, the stabilizer arm, which includes a first end pivotally attached to the frame, a locking pin operable to slidably move within the stabilizer arm, a cam surface on the frame, and a biasing member operable to bias the locking pin into engagement with the cam surface, the method comprising:
- moving the stabilizer arm from a usage position to a storage position, wherein the locking pin moves within the stabilizer arm in direction against the biasing force of the spring to move from contact with a usage range of the cam surface, over a protruding point on the cam surface, and into contact with a lock position of the cam surface,
- wherein a biasing force of the biasing member pressing the locking pin into contact with the lock position is greater than a rotational gravitational force acting on the stabilizer arm so as to lock the stabilizer arm in the storage position and prevent the stabilizer arm from inadvertently moving out of the storage position.
