Abstract
A main body provided with a pocket for accommodating a first chain link of another chain, and a lock lever which is capable of switching between a locked state and an unlocked state by pivoting, and which restricts disengagement of the first chain link from the pocket in the locked state, and allows the first chain link to disengage from the pocket in the unlocked state, which is resisted by an urging force of an urging member, wherein the lock lever is provided with a locking piece which projects from a pivot point toward the pocket side, and the locking piece projects toward a position in which movement of a second chain link in an escaping direction is restricted, a first operating piece extending to the side of the pivot point on which one chain is coupled, and a second operating piece extending to the opposite side.
Claims8
A shortening clutch for connecting one chain and another chain, the shortening clutch comprising:
- a main body coupled to the one chain and including a pocket for accommodating a first chain link of the another chain;
- and
- a lock lever which is pivotably attached to the main body through a pivot point having an urging member, is capable of switching between a locked state and an unlocked state by pivoting, and in the locked state, restricts disengagement of the first chain link accommodated in the pocket, from the pocket, while in the unlocked state in which the lock lever resists an urging force of the urging member, allowing the first chain link to disengage from the pocket,
- wherein the lock lever includes:
- a locking piece which, in the locked state, projects from the pivot point to the pocket side, in which the locking piece projects toward a position where the locking piece restricts movement of a second chain link of the another chain in an escaping direction, and the second chain link is adjacently coupled, on a side opposite to the escaping direction of the first chain link, to the first chain link accommodated in the pocket;
- a first operating piece extending from the pivot point toward a side where the one chain is coupled;
- and
- a second operating piece extending from the pivot point toward a side opposite to the side where the one chain is coupled.
A shortening clutch for connecting one chain and another chain, the shortening clutch comprising:
- a main body coupled to the one chain and including a pocket for accommodating a first chain link of the another chain;
- a lock lever which is pivotably attached to the main body through a pivot point, is capable of switching between a locked state and an unlocked state by pivoting, and in the locked state, restricts disengagement of the first chain link accommodated in the pocket, from the pocket, while in the unlocked state, allowing the first chain link to disengage from the pocket;
- and
- a posture maintaining means which is attached to the main body and maintains a posture that the lock lever has in one of the locked state or the unlocked state,
- wherein the lock lever includes:
- a locking piece which, in the locked state, projects from the pivot point to the pocket side, in which the locking piece projects toward a position where the locking piece restricts movement of a second chain link of the another chain in an escaping direction, and the second chain link is adjacently coupled, on a side opposite to the escaping direction of the first chain link, to the first chain link accommodated in the pocket;
- a first position which is provided in the lock lever and maintains the locked state of the lock lever by being given a force from the posture maintaining means;
- and
- a second position which is provided in the lock lever, maintains the unlocked state of the lock lever by being given the force from the posture maintaining means, and is present at a position different from the first position.
