Description

  The present invention provides a new drop-off mechanism that allows certain doors to be locked with reliable operation and prevents the rod from being lifted and lifted illegally by a hand or a tool from the gap between the floor and the lower arm of the door. It provides a lock.

In order to fix the door on one side of the double door and the child door of the parent / child door so that they do not normally open, attach a rod so that it digs into the summoning part below the heel of the door, and raise and lower the rod to raise the floor. There is a lock lock as a fitting to lock the door.

  In many cases, the lock lock is a rod (also called a bolt) embedded in the summoning part of the top and bottom of the door, which is lifted and lowered by a lever that operates by the action of the lever, and the door is locked by the lifting and lowering rod. Depending on the type and shape of the door used and the finish or shape of the floor surface, the rod can be inserted into the floor surface and not locked due to the short stroke (stroke) of the rod. The rod was lifted illegally by lifting the rod with a hand or a tool from the gap between the door and the lower arm of the door.

  Thus, the invention of Japanese Patent Application Laid-Open No. 9-158580 (hereinafter referred to as Patent Document 1) relates to an up-and-down lock that locks a door used as a gate of a garage or the like with a lock rod that moves up and down. Specifically, a lock-up lock that prevents the unlocking by lifting the lock rod from the outside is disclosed.

  The invention disclosed in Patent Document 1 is a lifting lock provided on a lock body attached to a door with a lock rod that moves up and down and engages with a receiving member at a lowered position, and a lock rod that is fixed to the door. The lock body is provided with a lock mechanism for forming a saw-toothed occlusal portion on both joint surfaces with a block that slides relative to the substrate and temporarily fixes the block to the substrate.

  In the invention of Patent Document 1, the substrate has a through groove, the lock mechanism includes a swingable lever, the block is arranged on one surface of the through groove of the substrate, and the other surface has The lever is arranged, the block and the lever are connected, and the block is pressed against the substrate by swinging the lever, and the occlusal portion is fitted, and the lock is a lifting lock.

  With the above-described configuration, the lock-up lock according to the invention of Patent Document 1 is raised when the lock is locked because the block holding the lock rod and the substrate to which the block is joined are engaged by the occlusal portion. You can prevent it from happening.

  Therefore, even if a space is provided on the lower surface of the doors, such as in a garage, the lock rod cannot be grasped and raised from the space by a hand or a tool. That is, since the locked state can be secured, security can be improved, and the lock bar can be arbitrarily set in accordance with the depth of the receiving hole and the lock bar can be fixed at an arbitrary position.

  Further, according to the lifting lock of Patent Document 1, since the occlusal portion has a sawtooth shape, the lock rod can be temporarily fixed at an arbitrary position, so that the mounting position of the lock body, the depth of the receiving member, etc. It is said that the above effects can be exhibited without being restricted.

  However, in the invention of Patent Document 1, the occlusal portion of the block that holds the lock rod and slides on the substrate and the occlusal portion that is engraved in the substrate fixed to the doors are directly moved by turning the lever. When it is engaged and fixed, and when the occlusal part consisting of serrated irregularities is engaged, if the positional relationship between the block and the substrate is bad, not only the temporary fixing operation can not be performed reliably, There is a drawback that the occlusal portion between the block and the substrate is worn or damaged early.

  Further, the operation of directly fitting and temporarily fixing the occlusal portion of the block and the occlusal portion engraved on the substrate by rotating the lever is performed even if the positional relationship between the block and the substrate is poor. Since there is no click feeling that can check the degree of engagement when the lever swings, it is easy to forcefully rotate the lever and always include the cause of damage to the occlusal part between the block and the board. This is the configuration.

Further, in the invention of Patent Document 1, when the receiving member (receiving hole) of the lock rod is on the floor or the ground, the receiving hole of the receiving member is blocked by an obstacle such as stone or earth, and the block and the substrate The occlusal portion between the two blocks is displaced, and it is not possible to confirm whether the occlusal portion between the block and the board is securely engaged by the click feeling when the lever is swung. Even in the case of an up-and-down lock having a mechanism in which the lock rod is not lifted illegally by a hand or a tool from the gap between the ribs, there remains a problem in terms of security.
