囲第(4)項記載の扉錠。[Scope of Claim for Utility Model Registration] (1) Two or more latch bolts that are permanently protruded in a temporarily locked state by a protruding holding member are provided at appropriate locations on a closing body such as a door, and the protruding holding members of these latch bolts are connected to an interlocking mechanism. A door lock characterized in that it is configured such that all the latch bolts can be unlocked simultaneously via the interlocking mechanism by operating the operating member of the first latch bolt. (2) The protruding holding member of the first latch bolt consists of a latch spring that always biases the latch bolt in the projecting direction, and a latch hub that has an engaging portion that engages with the latch bolt, and the rear part of the latch hub is connected to the interlocking mechanism and the shaft. 2. The door lock according to claim (1), which is a registered utility model, and further includes an operating shaft of an operating member such as a lever handle inserted into the hub hole. (3) The other latch bolt than the first one is provided with a locking piece that detachably engages with the engaging portion of the latch bolt to prevent the latch bolt from reversing. Door locks listed in ). (4) The interlocking mechanism includes a slider in which the latch hub of the first latch bolt is pivotally supported by a pin, and the slider is connected to both upper and lower ends of the slider via joints, and other latch bolts other than the first latch bolt can be moved in and out. A door lock according to claim (2) or (3) of the utility model registration claim, which comprises a connecting rod. (5) A recess is formed in a part of the connecting rod, and the rear end of the locking piece is brought into contact with the recess, and the front part of the locking piece is contracted inward by the elastic force of the spring. While detachably engaging with the engaging portion of the locking bolt, by moving the connecting rod up and down, the large diameter portion of the connecting rod can be used to push the front portion of the locking case outward against the elastic force of the spring. A door lock according to claim (4) of the utility model registration, which is configured to be expanded and released from engagement with a latch bolt. (6) A cam is pivotally attached to the tip side of the connecting rod via a backing plate, and the locking piece is detachably engaged with the engaging portion of the latch bolt by rotation of the outer peripheral edge of the cam. The door lock according to claim (4) of the utility model registration, which is configured to prevent the latch bolt from being reversed.
