Abstract

PROBLEM TO BE SOLVED: To maintain the function of a door by providing a pair of stopper means on an inner frame and an outer frame and by regulating a stop position by the stopper means at the time when the inner frame moves in the wall thickness direction due to deformation of the outer frame. SOLUTION: An outer frame 2 an inside of each side of which is inclined in the thickness direction of a wall 1 and having a projected part 5A of a stopper means is installed on an opening part of the wall 1. Thereafter, an inner frame 3 an outside of each side against each of the sides of the outer frame 2 of which is inclined in the thickness direction of the wall 1 and having a projected part 5B of the stopper means is installed on the inside of the outer frame 2. Consequently, when the outer frame 2 is deformed due to an earthquake, etc., and an interval between its left and right sides becomes narrow, the inner frame 3 is moved in the thickness direction of the wall 1 due to an inclined surface of each of the sides, deformation of the inner frame 3 is prevented, and jumping out of the outer frame 2 is prevented by the projected parts 5A, 5B of the stopper means 5. Accordingly, a state of the inner frame 3 and a door 4 supported by the outer frame 2 is maintained, it is possible to open and close the door 4 without trouble.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device installed at a doorway to a building or a room.

[0002]

2. Description of the Related Art Conventionally, a device of this type is,
-36870, 56-29189, 56-
As described in Japanese Patent No. 20868, there is proposed a door frame and an end surface of the door which are inclined in the thickness direction of the wall so that the door is moved outside the door frame when the door frame is deformed. .

[0003]

When the door frame is deformed due to an earthquake or the like, the door pops out of the door frame, an opening is formed, and it is possible to freely enter and exit, which is convenient for evacuation. However, since the function as a door device is lost, anyone can freely go in and out, which is not preferable for crime prevention.

An object of the present invention is to provide a door device that can maintain the function as a door device even when the outer frame is deformed and the inner frame and the door move in the thickness direction of the wall.

[0005]

[Means for Solving the Problems] The above object is to provide a door device installed at a doorway to a building or room,
An outer frame fixed to a wall of a building or a partition wall, an inner frame housed in the outer frame, an openable / closable door attached to the inner frame, and a stopper means, and at least the outer frame. The left and right sides and the sides of the inner frame facing them are inclined in the thickness direction of the wall, and the stopper means stops when the inner frame moves in the direction orthogonal to the wall due to the deformation of the outer frame. Achieved by configuring the position.

With the above construction, when the outer frame is deformed due to an earthquake or the like, the inclined surface receives the force of moving the inner frame in the thickness direction of the wall and then moves, but the stopper means prevents the inner frame from moving. Since the inner frame does not pop out from the outer frame, it stops in the state of being locked to the outer frame, no opening is formed, and the inner frame is hardly deformed, which hinders the opening and closing of the door. Can be done without.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is applied to a door device for a doorway of a building will be described below with reference to FIGS.

FIGS. 1 and 2 are horizontal cross sections of one embodiment, FIG. 1 showing a normal state, and FIG. 2 showing a state when the outer frame is deformed. FIG. 3 is a front view of one embodiment.

In the figure, 1 is a wall of a building, 2 is an outer frame attached to the opening of the wall 1, 3 is a quadrilateral inner frame housed inside the outer frame 2, and 4 is an inner frame 3. The door 5, which is attached so as to be openable and closable, shows a stopper means composed of a protrusion 5A formed on the outer frame 2 and a protrusion 5B formed on the inner frame 3. Inner side of each side of the outer frame 2 and the inner frame 3 facing the inside
2 is inclined in the thickness direction of the wall 1, and as shown in FIG. 2, when the outer frame 2 is deformed due to an earthquake or the like and the left and right spaces are narrowed, the inclined surface 2A, It is configured to prevent the deformation of the outer frame 2 from reaching the inner frame 3 by moving the inner frame 3 in the thickness direction of the wall 1 by 3A. The stopper means 5 is for preventing the inner frame 3 from jumping out from the outer frame 2 when the inner frame 3 moves in the thickness direction of the wall 1. As a result, even if the outer frame 2 is deformed (displaced) as shown in FIG. 2, the inner frame 3 and the door 4 remain supported by the outer frame 2 even if they move in the thickness direction of the wall 1. , It prevents the door from coming off and forming an opening. Therefore, opening and closing can be performed without trouble, evacuation in an emergency is possible, intrusion of a suspicious person can be prevented, and the function of the door device can be maintained.

In the above-described embodiment, the inclined surface is the outer frame 2.
Although it is formed on four sides of the inner frame 3, it may be formed on only two opposite sides (left and right or top and bottom). Further, although the stopper means 5 is formed integrally with the outer frame 2 and the inner frame 3, the outer frame 2 and the inner frame 3 have only inclined surfaces, and a separate stopper means is interposed between them. Also, the same effect can be expected.

[0011]

As described above, according to the present invention, there is provided a door device which can maintain the function as a door device even if the inner frame moves in the thickness direction of the wall due to the deformation of the outer frame of the door. Can be provided.
