Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a doorway for a building, which is installed at a doorway of a building to facilitate access.

[0002]

[Prior art]

 With the development of science, building technology has advanced, building materials have been developed, and new ones have been sold. Under such circumstances, there are sliding doors, single-opening doors, double-opening doors, etc. even for entrance doors, and there is not much change in the basic structure, but it is lighter and more durable and easy to use luxuriously to fit the whole building or room. Has been coming.

[0003]

[Problems to be solved by the device]

 However, even with doors that have been made in this way, if the building tilts and the outer frame deforms due to an earthquake or the like, the doors may not be opened or closed and it may not be possible to escape to the outside. It was difficult to escape from the doorway made of steel, which was very inconvenient for earthquake countermeasures.

[0004]

[Means for Solving the Problems]

 The present invention eliminates such an inconvenience, and even if the outer frame or the like is deformed and the entrance door cannot be opened or closed, it is possible to escape to the outdoors. Japanese Patent Application No. 7-5422 (Registration No. 3017417) No.) is further improved to provide a doorway for buildings. In other words, the outer side of the inner frame is tilted so that the front plate side of the child door body, which is a rectangular frame-shaped inner frame with the front plate and the back plate, is wider than the back plate side. A vertical frame and a horizontal frame, each of which is a slanted surface, is provided with two outer frames and two inner frames on a frame-like frame body. It can be opened and closed by cutting out along the inside of the vertical frame and the horizontal frame on the inner plate and making mounting holes, and inserting the main body of the child door into the mounting hole so that the inclined surface of the vertical frame and horizontal frame matches the sub-door main body. In the doorway that is to be installed at the door, a step surface is provided in the middle of the inclined surface of the vertical frame, horizontal frame, and inner frame so as to be parallel to the outer plate or front plate, and the vertical frame with the packing sandwiched.・ The contact surface of the horizontal frame and the contact surface of the inner frame are in contact with each other.

[0005]

[Action]

 In this way, by installing the main body of the main door that has the inclined surface with the contact surface on the outer periphery, the main body of the main door can be opened from the vertical and horizontal frames even if the main door is deformed by an earthquake. Since it is easy to detach from the door, you can easily open it by holding the handle and applying force, and you can escape by opening the child door body from the room without opening the parent door body. In the closed state without using the child door, the child door was installed to sandwich the packing and hit the contact surface to maintain airtightness, so there is no air circulation and it is used only by the parent door. There is.

[0006]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 shows the entire main door, and 2 is a main door body composed of a frame body 3 forming a rectangular frame shape, and an outer plate 4 and an inner plate 5 provided so as to cover both sides. The vertical frame 6 and the horizontal frame 7 provided with inclined surfaces 6a, 7a other than a right angle in the cross section so that the contact surfaces 6b, 7b are parallel to the outer plate 4 or the inner plate 5 at different stages in the middle of the frame body 3 Two vertical frames are vertically arranged inside, and two horizontal frames are horizontally arranged at appropriate intervals so that the inclined surfaces 6a, 7a face each other to form a trapezoid, and the vertical frames are formed on the outer plate 4 and the inner plate 5. Notch mounting holes 4a and 5a are formed along the inner side of the frame 6 and the inside of the lateral frame 7. Reference numeral 8 denotes a handle made of a cylinder lock, which is provided near the center of the inside of the vertical frame of the frame body 3. A hinge 9 is provided outside the frame 3 of the main door body 2 on the side opposite to the handle 8 and is openably and closably provided on the outer frame 10. Reference numeral 11 denotes the entire child door, 12 is a rectangular frame-like shape, and an outer peripheral surface is provided with an inclined surface 13a which inclines in the same direction as the inclined surfaces 6a, 7a, and a contact surface 13b corresponding to the intermediate contact surfaces 6b, 7b. It is a child door main body in which a front plate 14 and a back plate 15 are provided so as to cover both surfaces of an inner frame 13 provided in different steps, and a slanted surface 13a is formed in the vertical frame 6 and the horizontal frame 7 and a slanted surface 6a, 7a and insert the contact surfaces 6b and 7b so that the contact surface 13b abuts the packing 16 through the packing 16, and the hinge 17 is provided on the same side as the hinge 9 so that the child door body 12 can be opened and closed. There is. Reference numeral 18 denotes a handle made of a cylinder lock or the like, which is provided on the side opposite to the hinge 17.

In use, it is attached and used in the same manner as a conventional door. Even if the main door 1 is deformed and cannot be opened / closed due to an earthquake or the like, the outer periphery of the child door main body 12 has a trapezoidal shape, so that the vertical frame 6 and the horizontal frame 7 can be pushed by pushing in the opening direction. You can push it open without being restrained by. Further, during use, the main door body 2 can be used as one piece even if the contact surfaces 6b, 7b, 13b and the packing 16 keep airtightness and a child door is provided.

[0008]

[Effect of device]

 As described above, according to the present invention, since the outer periphery of the sub-door main body is provided with the inclined surface and the contact surface is provided inside the main door body so as to keep airtightness with the packing, the sub-door main body is separated from the vertical frame and the horizontal frame. Even if the outer frame or frame is deformed due to an earthquake or the like, you can easily open the child door body and escape from the room if you apply force with the handle even if the outer frame or frame is deformed, saving human life and saving damage. It is extremely excellent in practical use because it can be reduced in number and the air-tightness can be maintained by the contact surface and packing during use so that it is integrated with the parent door except when the child door is opened and closed. It was an invention.
