Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door in a building, and more particularly to a sliding door which automatically closes when opened. The “sliding door” in the present specification including the claims also includes a hanging door. The “sliding door” is not limited to a single sliding door, a sliding door, a sliding door and the like.

2. Description of the Related Art Japanese Patent Laid-Open No. 10-11514 discloses a sliding door in a building which automatically closes when opened.
No. 6 (hereinafter referred to as "conventional sliding door") is known. In this conventional sliding door, the sill of the sliding door is inclined downward in the closing direction of the sliding door, and the lower edge of the sliding door is inclined downward in the closing direction of the sliding door. When the hand is released, the sliding door automatically moves in the closing direction along the threshold by its own weight.

[0003]

However, the conventional sliding door has the following problems.

(A) Since the sliding door sill is inclined at the same angle over the entire length of the sill, when the open sliding door is automatically closed, the sliding door is gradually accelerated on the inclined sill. That is, when the sliding door is closed, it collides with the vertical frame of the opening without being decelerated. Therefore, not only an unpleasant collision sound is generated when the sliding door is closed, but also an elderly person, a child, etc., may inadvertently injure the hand or finger between the sliding door and the vertical frame of the opening. The sliding door may be damaged. In order to prevent this, in the above-mentioned conventional sliding door, an impact buffer is attached to the vertical frame of the opening, but even when such an impact buffer is attached, the sliding door is attached to the vertical frame of the opening. Colliding at high speeds is unpleasant and undesirable.

(B) Since the sill of the sliding door is inclined at the same angle over the entire length of the sill, if the sliding door is opened and then the hand is released, the sliding door immediately starts moving in the closing direction without stopping. . That is, the sliding door cannot be kept open. Therefore, in the above-mentioned conventional sliding door, a locking mechanism for the sliding door is attached to the vertical frame of the opening in order to stop the sliding door in an open state. However, when such a locking mechanism is provided, it is troublesome to operate the locking mechanism when stopping the sliding door in an open state and closing the opened sliding door.

(C) Since the sliding door sill is inclined at the same angle over the entire length of the sliding door, if the sliding door is opened and then the hand is released, the sliding door immediately starts to move in the closing direction. As a result, the person who opened the sliding door may close the sliding door before passing through the opening, and may collide with the person.

The present invention has been made to solve the above-mentioned problems in the conventional sliding door.

[Effect of the invention] [Sliding door of claim 1] The sliding door of claim 1 exhibits the following excellent effects.

When the sliding door in the closed position is moved in the opening direction by hand, and the sliding door on the opening side of the sliding door is released on the inclined portion of the threshold, the sliding door automatically moves in the closing direction. At first, the speed is reduced at the second substantially horizontal portion of the sill, and it stops by lightly touching the vertical frame of the opening. That is, when the sliding door is automatically closed, the sliding door decelerates at the second substantially horizontal portion of the threshold, so that the sliding door does not strongly collide with the vertical frame of the opening. In other words, the sliding door does not make a collision noise with the vertical frame. In addition, there is no possibility of injuring the hand or finger between the sliding door and the vertical frame.

When the sliding door in the closed position is moved in the opening direction by hand, and the sliding door on the opening direction side of the sliding door is put on the first substantially horizontal portion of the threshold, the sliding door is automatically moved to the position. Stop. That is, the sliding door can be kept open without operating the locking mechanism or the like. In this state, if the sliding door is lightly pulled by hand in the closing direction, the sliding door is automatically closed. That is, there is no need to operate the locking mechanism or the like even when closing the sliding door.

If the sliding door in the closed position is moved in the opening direction by hand, and the sliding door on the opening side of the sliding door is on a gentle slope of the threshold, the sliding door is released.
Since the sliding door automatically starts moving slowly in the closing direction, there is an appropriate time between opening the sliding door and automatically closing the sliding door. Thus, a person who has opened the sliding door can slowly pass through the opening before the sliding door closes.

[Claim 3] The sliding door in the closed position is moved in the opening direction by hand, and the sliding door on the opening direction side of the sliding door is dropped into the first recess formed in the first substantially horizontal portion of the threshold. Thereby, the sliding door can be more reliably stopped at the position and locked at the position. In this state, if the sliding door is lightly pulled by hand in the closing direction, the sliding door automatically moves, and stops at the closed position.

When the sliding door is closed, the sliding door in the closing direction of the sliding door is dropped into a second concave portion formed in a second substantially horizontal portion of the sill, so that the sliding door is vertically positioned at the opening. It can be locked in contact with the frame. In this state, the sliding door is opened by lightly pulling the sliding door in the opening direction.

[Sliding door of claim 5] The sliding door of claim 5 exhibits the same effect as the sliding door of claim 1.

[Sliding door of claim 6] The sliding door of claim 6 exhibits the same effect as the sliding door of claim 2.
