Abstract

(57) [Abstract] [Purpose] To solve the inconvenience when the door is housed in the door frame by making the inner surface of the door abut against the opening door frame. [Structure] An area of a door 5 of an opening / closing opening 1 provided in a wall portion 3 of a building is formed larger than an area inside a frame of the opening 1. The inner surface of the door 5 is brought into contact with the edge of the door frame 4 protruding from the wall surface, and is attached to the door frame 4 so as to be openable and closable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door having an opening / closing opening provided on a wall surface of a building.

[0002]

[Prior art]

 The door of a normal building has almost the same size as the inside area of the opening in the wall, and the entire door is placed in the opening with the door frame on the inner edges of the three sides except the lower side. It is installed there.

[0003]

[Problems to be solved by the device]

 In such a structure, dimensional accuracy of the door with respect to the opening is required, and it is also necessary to adjust the interval required for opening and closing the door depending on the position of the shaft that is the center of rotation of the hinge used for mounting. Furthermore, in wooden buildings, etc., distortion often occurs over time, which makes it difficult for the side edges of the door to come into contact with the door frame to open and close, which causes the inconvenience of adjusting the door gap each time. Out. There is a problem in that it is difficult to freely design the contour shape of the door because it is restricted in terms of design because the entire door fits in the opening.

The present invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to make the door installation easy by changing the means for attaching the door to the opening from the conventional one. The object of the present invention is to provide a new door in which the inconvenience of opening and closing the door due to aging does not easily occur, and the contour shape of the door is not limited to the shape of the opening and can be freely performed.

[0005]

[Means for Solving the Problems]

 A feature of the present invention for the above-mentioned purpose is a door having an opening / closing opening provided in a wall portion of a building, the door area being formed larger than the frame inner area of the opening, and the inner surface of the door protruding from the wall surface. The door frame is attached to the door frame so as to be openable and closable.

[0006]

[Work]

 In the above configuration, the opening is closed by the contact between the inner surface of the door and the door frame, and the door side end of the hinge mounting part is in contact with the wall surface due to the rotation space formed by the edge of the door frame protruding from the wall surface. Open without rotating.

[0007]

【Example】

 In the figure, 1 is a required opening that serves as an entrance / exit of a building, and the lower edge is in contact with the floor 2 and is installed on the wall 3. The door frame 4 has inner and outer edges 4a on the inner edges on three sides except the lower side. 4b is provided so as to project from the wall surface.

Reference numeral 5 denotes a door, which is formed so that the door area is larger than the inner product of the opening 1 to some extent, and three sides of the inner surface of the door are in contact with the outer edge 4 a of the door frame 4, A hinge 6 is attached to a vertical frame on one side of the door frame 4 so as to be openable and closable.

The hinge 6 may be a commonly used hinge such as a pivot hinge or a take-out hinge, and is provided with screws on the outer end surface of the edge 4a and the inner surface of the side edge of the door 5 with the shaft portion outside. The door 5 is opened and closed with the shaft portion as the center of rotation.

In this door 5, the opening 1 can be closed by the contact between the inner surface of the door and the door frame 4, and the edge 4 a protruding from the wall surface allows the hinge mounting portion to be attached by the preformed rotary space 7. The door end 5a rotates and opens without contacting the wall surface.

Reference numeral 8 is a door closer having a conventional structure having a handle 9 inside and outside. The door closer 8 is penetrated through a front end portion of the door 5, and an engaging hole 11 is provided inside a vertical frame facing an engaging rod 10 of the door closer 8. There is a mark. Although not shown in the figure, a locking device is provided at the mounting portion of the door closer 8.

As described above, in the door 5 in which the door area is formed larger than the inner area of the frame of the opening 1 and the inner surface is in contact with the door frame 4 on three sides, the side edges other than the mounting side have the door frame 5 4A and 4B, the side edge shape can be formed by a curved line.

[0013]

[Effect of device]

 In this invention, as described above, the area of the door 5 of the opening / closing opening 1 is formed larger than the area inside the frame of the opening 1, and the inner surface of the door 5 is the edge of the door frame 4 protruding from the wall surface. Since it is attached to the door frame 4 so as to be openable and closable, the following effects are achieved.

Since the door is located outside the door frame, the dimensional accuracy is not required as much as when the door is housed in the door frame, and it is not necessary to adjust the gap with respect to the door frame. , The construction becomes easy.

Since the inner surface of the door is in contact with the door frame to close the opening, there is no need to form a step for receiving the door also as a blindfold inside the door frame, and the entire opening is hidden. The effect on crime prevention is also great.

Even if the opening is distorted due to the passage of time, the door located outside the door frame does not come into contact with the inner surface of the door frame due to the distortion, so there is no inconvenience of opening and closing the door due to the distortion. Even when used for a long period of time, opening and closing are as smooth as when building.

Since at least the mounting side is not restricted by the door frame, it is possible to freely design a uniform door contour shape, and it is possible to manufacture an unprecedented door.
