Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lock device that maintains a sealed state in a sealing device that seals the gap between the top and bottom of a closed door.

[Conventional technology and its problems]

Conventionally, a sealing device for sealing the gap between the top and bottom of a closed door in a sliding door such as a partition door or a pivoting door is equipped with a sealing base that can be moved up and down relative to the door. is configured to move up and down in conjunction with the forward and backward movement of an operating rod extending along the frontage direction of the door, and as the door closes, the operating rod moves against the frontage side of the room or the end surface of other partition doors, etc. It touches the opposing member and moves backward,
The sealed base body is designed to protrude toward the floor or ceiling.

In this case, the prior art Japanese Patent Application Laid-Open No. 49-19644 discloses a method in which a lever, whose middle portion is fitted onto an operating rod, is pivotally mounted inside the door so as to be rotatable along the axial direction of the operating rod. By engaging the lever with the operating rod, the operating rod is held in the retracted position, and by pressing the lever protruding from the side end surface of the door, the lever is rotated in the disengagement direction. It is proposed that the actuating rod be moved forward.

This configuration has the advantage that the operating rod cannot be moved forward as the door closes, but in order to move the operating rod forward, the rod must be pressed each time. I had a problem that took a lot of time to fix.

In order to solve this problem, the present applicant proposed in the earlier application, Utility Model Application No. 56-14180 (Utility Model Application No. 57-127789), that the operating rod can be locked in the retracted state when the door is closed, and proposed a structure in which the locking state of the operating lever is automatically released when the door is opened. The present application is a further development of this.

[Means for solving problems]

Therefore, in the present invention, a sealing base extending along the frontage direction of the door is attached to either the upper end or the lower end or both of the sliding door so as to be movable up and down with respect to the door, and the sealing base and the door are connected to each other. An operating rod extending in the direction of the door frontage is disposed in a portion between the two so as to be movable in the direction of the frontage of the door, and the operating rod is configured to move forward toward the side end surface of the door in the frontage direction. A spring is provided which biases the operating rod in the same manner, and when the door is closed, the operating rod moves backward when it comes into contact with a member such as a kicker facing the end surface in the frontage direction of the door. The sealing base moves in a direction away from the door depending on the situation, while an operating rod is disposed at a side position of a locking rod which is pivotally supported in the middle part of the door so as to be movable up and down. The front part of the locking rod is provided with an inclined engagement part that engages with the opposing member in the retracted position when the operating rod moves backward; A locking portion that locks the operating rod so that it cannot move forward is provided, and the locking rod is vertically moved through an appropriate angle by sandwiching the operating rod vertically between the inclined engaging portion and the locking portion. The locking lever is disposed at a lateral position of the operating lever, and the inclined engagement portion of the front part of the locking lever is connected to a member facing the side end surface in the frontage direction of the door, so that when the door is opened, the locking lever engages the locking lever. This is related to the release of the operating rod.

[Functions and effects of the idea]

With this configuration, as the door is closed, the tip of the operating rod comes into contact with a member such as a kicker that faces the end surface in the frontage direction of the door, and the operating rod moves backward to move the sealing base from the door to the floor. The door protrudes toward the ceiling and closes the gap between the door and the floor or ceiling.
It is held in its retracted position so that it cannot move forward.
That is, the operating rod is locked in the retracted position.

When the closed door is moved in the direction of opening, the tip of the locking rod moves in the direction of releasing the locking between the locking rod and the operating rod due to the relationship with the opposing member such as the locker. The released actuating rod is moved forward by the biasing spring force, and the sealing base is also moved back toward the door. That is, when the door is opened very slightly, the locking lever and the operating lever automatically disengage, and the operating lever moves forward, causing the sealing base to move back relative to the door.

As described above, in the present invention, since the operating lever of the sealing device is unlocked as the door moves to open, it is possible to reliably maintain the seal at the upper and/or lower end of the door in the closed state.
This has the effect of making it extremely easy to open and move the door.

Moreover, the locking lever is provided with an inclined engagement portion at the front thereof that engages the opposing member at the retreated position when the operating lever moves backward, and the operating lever is provided at the rear of the locking lever. A locking portion is provided that locks the operating rod in the retracted position so that it cannot move forward. Therefore, the locking rod must move up and down in response to the engagement and release of the operating rod, but in the present invention, the operating rod can be moved up and down by the inclined engagement portion and the locking portion of the locking rod. Since the locking rod is placed on the side of the operating rod so that the locking rod can be moved up and down at an appropriate angle, the locking rod can be placed above or below the operating rod, and the locking rod can move up and down at an appropriate angle. Compared to a configuration in which the locking lever moves up and down, the present invention does not require a large vertical space for the up and down movement of the locking rod, and has the effect of making the entire device more compact.
