Abstract
A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.
Claims18
A lock, having a common fastening member disposed at an identity opening at a junction of a body and a door capable of being opened and shut freely, wherein the lock is mounted on a plurality of lock mounting portions of a lock clutching member disposed at the body, the door or both to receive a latch and a false lock, using a space created to remove the lock clutching member and thereby mount the lock on or dismount the lock from the lock mounting portion in a locked state, wherein the latch protrudes or the false lock is in an upright state, characterized in that:
- the lock has a means of opening and shutting the identity opening by two means, wherein one of the two means is, when any one of the locks is in a locked state and cannot be unlocked, adapted to controllably keep the fastening member in an unlocked state or a locked state with the latch moving in response to operation of a locking/unlocking-oriented operating portion of any other said lock, wherein another means is, when any one of the locks is in an unlocked state and cannot be locked, adapted to controllably keep the fastening member in a locked state or an unlocked state with the latch attributed to any other said lock and stop the fastening member upright forcibly with the false lock of the locks.
An identity opening, disposed at a point at which a body and a door capable of being opened and shut freely abut against each other, having locking/unlocking operating members, a common fastening member and a stopping member, and capable of stopping the common fastening member forcibly, characterized in that the body and the door are opened and shut with means comprising:
- an operating means of using, when any one of the locking/unlocking operating members cannot perform an unlocking operation, any other said locking/unlocking operating member to perform a locking/unlocking operation;
- a forcibly stopping means of replacing, when any one of the locking/unlocking operating members cannot perform a locking operation, the locking/unlocking operating member incapable of performing a locking operation to perform a locking/unlocking operation by the operating means and using the stopping member of the identity opening to perform a locking operation;
- and another operating means of using any other said locking/unlocking operating member to perform a locking/unlocking operation.
A lock clutching member, whereby a lock is mounted on and dismounted from a lock mounting portion, characterized by a means of removing the lock clutching member of the lock mounting portion to thereby create a space and using the space thus created such that the lock can be mounted on and dismounted from the lock mounting portion even if a false lock and a latch of the lock are in one of a protruding state and a receiving state.
A lock mechanism, having an inclined plane capable of wedging apart a protective member or the protective member and a latch-like member, characterized by a corresponding movement means of being proportional to a pressing force of the latch-like member being abutted against to thereby produce a wedging effect from the inclined plane and push the protective member inward in a locking direction, thereby augmenting/reducing a stopping force.
A horizontal stabilizing member, disposed at a local point of an inclined plane of a latch-like member and adapted to keep the inclined plane horizontal, characterized by a means of pressing against, under a specific pressing force, the horizontal stabilizing member being abutted against to form an angle of the inclined plane and produce a wedging effect with the angle of the inclined plane of the latch-like member, thereby enhancing/reducing the locking resulting from the press exerted in a stopping direction while being proportional to the pressing force.
