Description

  The present invention relates to a mounting structure for inner and outer support seats attached to a wall surface of a door and a latch lock provided with the support seat mounting structure.

  Patent Document 1 states that “inner and outer support seats (mounting seat plates) connected to the inner and outer walls of a door through a plurality of fixing members in an opposing state, and vertical support shafts (vertical shafts) to these support seats. The mounting structure of the inner and outer support seats, each of which is pivotally supported via a shaft and is composed of inner and outer operation members that rotate in the horizontal direction by a required amount, is described.

  Further, Patent Documents 2 and 3 specifically describe that when an internal / external operation member is operated, an operation member in the lock box is actuated to rotate a latch locking piece for locking the latch in a direction to release the latch. The configuration is described.

  The structure for attaching the inner and outer support seats is applied to a lock (latch lock) called “push-pull lock” or “handle lock” by those skilled in the art.

  Therefore, regardless of the name, when one of the internal and external operation members is pushed (pushed) or pulled (pulled forward) in the horizontal direction, the operation of the latch lock in the lock box is performed based on the operation force of the operation member. A member (for example, a sliding member) moves or rotates in the horizontal direction, and a latch locking piece that locks the latch directly or via an interlocking piece that interlocks with the operating member rotates in the direction of releasing the lock.

  In other words, the inner and outer mounting seats of Patent Document 1 have the same configuration both inside and outside, and the inner and outer operating members are respectively operated in the horizontal direction via the vertical support shaft (vertical axis). It was a configuration.

  By the way, in the latch lock to which the push-pull type operation member is applied, there is a demand for a mounting structure for the inner and outer support seats that can operate the operation member not in the horizontal direction (left-right direction) but in the vertical direction (up-down direction). Has been.

  Of course, there is no problem with pushing or pulling the operating member in the horizontal direction to open the door. However, for example, when operating the operation member with the shopping bag suspended from the wrist, it is a more natural operation if the user pulls the upper end of the outer operation member and can perform the “pull operation” in the downward direction. Is easy.

Therefore, there is a demand for a mounting structure for the inner and outer support seats that can support the inner and outer operation members with a horizontal support shaft (horizontal axis) and a latch lock provided with the support seat mounting structure.
