Description

  The present invention relates to a seat for a sickle lock that is embedded in a pillar or a vertical frame of a sliding door and engages with a hook of the sickle lock when the sliding door is closed.

  Conventionally, sickle locks have been widely used as simple locking means for connecting sliding door end surfaces and columns or vertical frames in contact with each other. As shown in FIG. 5 (A), this sickle lock is engraved in a sickle lock body 1 embedded in a carved groove carved in an end face of a sliding door 4 or the like, and a frame body 5 such as a pillar or a vertical frame. The entirety embedded in the insertion groove 51 is made up of a bowl-shaped seat 2, and the hook 11 of the sickle lock body 1 is rotated to rotate the hook 22 of the sickle tablet body 1 from the opening 22 provided on the front plate 21. It is locked by inserting the hook 11 while turning it and hooking it on a receiving portion 23 formed at the end of the opening 22 of the front plate 21.

  By the way, such a sickle lock employs a trigger 12 that causes the sickle lock body 1 to abut against the front plate 21 of the seat 2 to rotate the hook 11 when the hook 11 is rotated during locking. (See, for example, Japanese Patent Publication No. 56-33553, Japanese Utility Model Publication No. 3-24778, Japanese Patent Laid-Open No. 8-86132, etc.).

  For these sickle locks, after closing the sliding door, the sickle member is manually protruded and hooked to the latching part of the door frame body, and also when opening the sliding door, the sickle member is manually detached from the latching part and into the lock case. Since the hook 11 is automatically locked and unlocked when the sliding door 4 is opened and closed as compared with the case in which the sliding door is opened after being stored (see, for example, Japanese Utility Model Publication No. 5-47263). In addition, it is very convenient because the unlocking operation can be performed only by opening and closing the sliding door 4 without requiring the unlocking operation.

  And the said conventional sickle lock is shown in FIG. 5 (A), and the sliding door 4 is pressed by pressing the trigger 12 arrange | positioned in the sickle lock main body 1 so that it can protrude and retract in the vicinity of the opening part 22 in the front board 21 of the seat 2. The operation of the hook 11 is cooperated with the opening / closing operation.

  For this reason, conventional sickle locks are sold as a set of a pair of seats 2 designed along the structure of the sickle lock body 1 and the trigger 12 of the sickle lock body 1. It is necessary to form the engraved groove for embedding each seat according to the set seat. Therefore, the shape of the seat and the engraved groove that fits each type of sickle lock body must be changed each time. It was very inconvenient.

  Therefore, it is conceivable to reduce the product price by providing a seat that can match a plurality of sickle lock bodies depending on the size of the hooks and the payout, and to make it possible to replace only the sickle lock body after installation.

  The common receiving seat 2 for corresponding to many sickle lock bodies 1 can be formed by forming the opening 22 formed in the front plate 21 vertically and adjusting the position of the receiving portion 23 of the opening 22. Is done.

  However, the hook 11 can be adjusted by an adjusting mechanism (not shown) of the receiving portion 23. However, when the position of the trigger 12 is close to the hook 11, as shown in FIG. The current situation is that the sickle lock body 1 and the seat 2 are sold as a set, and it is necessary to always manufacture and sell the seat according to the sickle lock body. There is a problem.
