Abstract

PURPOSE: To pull small doors for the superposition thereof, and freely open and close the doors to the full extent of frontage under the application of simple constitution by causing a boss on the reverse side of a front door frame to slide in a groove formed on the front side of a rear door. CONSTITUTION: When a front door A is pulled in a right direction, with two front and rear sliding doors A and B closed, a boss 1 formed on the reverse side of the frame of the front door A slides in a groove 2 horizontally formed on the front side of the rear door B, thereby keeping frontage half opera. Also, when the door A is further pulled in a right direction and the boss 1 reaches the right end of the groove 2, the door A drags the door B, and both move into a storage space 5 together, thereby keeping the frontage wide open. Also, when the door A is pulled in a left direction from a totally close state, the boss 1 slides in the groove 2. Then, when the boss 1 reaches the left end of the groove 2, the frontage becomes half close. When the door A is further pulled in a left direction, the door A drags the door B via the boss 1, and both travels in a left direction. Then, the door B stops at a door stopper 6 on a head jam, upon contact therewith, and the door A moves to a totally close position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door capable of opening a maximum frontage in a minimum space, and more particularly to a sliding door which can be escaped in an emergency by providing a passing door.

[0002]

2. Description of the Related Art Conventionally, in order to open and close a door with a wide frontage, a door commensurate with the frontage is required, and the door becomes large and heavy and costly. Although it is found in elevators that doors are made smaller and can be stacked, they are not simple mechanisms and cannot be applied to ordinary doors.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sliding door in which small doors are stacked with a simple mechanism to obtain a wide open frontage. Furthermore, if a sliding door is attached to the sliding door, it is possible to escape without opening the sliding door in an emergency.

DISCLOSURE OF THE INVENTION The present invention relates to two doors that open and close between a groove of an upper kamoi and a rail of a lower sill, each of which is provided separately in the middle of the front side of a rear door, and the groove. And a boss provided at the same height as the groove on the back side of the frame of the front door that overlaps the rear door that slides, and a door contact is provided in the middle of the rear door groove of the upper kamoi. It is a sliding door.

The present invention will be described with reference to FIGS. 1 and 2.
Open the front door A from the left to the right in the figure with a puller. A boss 1 is provided on the back side of the front door of a frame in which the front door A and the rear door B overlap when closed, and this is fitted in a groove 2 horizontally provided at the same height as the boss in the middle of the rear door B. Mari, front door A
As the boss is opened, the boss slides in the groove, and the boss reaches the end point of the groove 2 of the rear door B. At this stage, the front door A and the rear door B are almost overlapped with each other, and the frontage is half open (state of FIG. 2B).

When the front door A is further pulled to the right, the rear door B is also dragged by the action of the boss of the front door and moves to the right, and finally the rear door B and the front door A move to the end of the door storage space 5. Stop. As a result, the frontage is fully opened.

On the contrary, when closing the door from the fully opened state, pulling the puller of the front door A to the left moves the front door A to the left, and the boss 1 of the front door A slides in the groove of the rear door B. When reaching the left end of the groove (the frontage is in a semi-closed state here), the rear door B is dragged and moved to the left. When the rear door B reaches the door contact 6 in the middle of the groove for the rear door B of the upper Kamoi, it stops here and does not move any further, but only the front door moves until it is fully closed.

Further, by providing a passing door 3 in the lower half of the front door A and providing a lock 4 which can be easily removed, when the door is not opened due to an earthquake or the like, the passing door can be opened by unlocking it. You can and can escape from there. The passing door 3 may be of a type that pulls it toward you, and the lock 4 and its mounting position may be normal.

Both the front door A and the rear door B are glass doors with crosspieces in the figure and the lower half is a plate, but any material may be used as long as it has the mechanism of the present invention.
Aluminum or iron doors or decorative boards can be used.

[0010]

According to the present invention, by combining two narrow doors, it is possible to freely open and close from a narrow opening to a wide opening without using a large and heavy door.

Further, the attached door is convenient for escape in an emergency.
