Abstract
A locking mechanism comprises a base comprising a pair of arms projecting therefrom and defining an open mouthed recess for receiving a member to be selectively retained in the recess. The mechanism further comprises a pair of locking elements mounted between said pair of arms for rotational movement between a retracted position in which they permit access to the recess and an extended position in which they extend at least partially across the mouth of the recess. The arms comprise respective guides to guide the movement of said locking elements between said retracted and extended positions. The mechanism further comprises a drive for simultaneously moving the locking elements in opposite rotational directions. The drive may comprise a drive shaft having left handed and right handed threaded portions.
Claims19
A locking mechanism comprising:
- a base defining an open mouthed recess for receiving a member to be selectively retained in the recess;
- a pair of locking elements mounted for rotational movement between a retracted position in which they permit access to the recess and an extended position in which they extend at least partially across the mouth of the recess;
- and
- a drive for simultaneously moving the locking elements in opposite rotational directions;
- wherein said base comprises at least one arm, said at least one arm comprising respective guides to guide the movement of said locking elements between said retracted and extended positions;
- wherein said locking elements comprise guide elements for engagement with said guides and said guides comprise arcuate channels formed in said at least one arm;
- and
- wherein said locking elements comprise guide pins for engagement with said channels.
