Description

[Detailed explanation of the idea] Industrial applications This invention relates to doors such as entrance doors.

BACKGROUND TECHNOLOGY In general, modern buildings such as residences often have a variety of external appearances in order to change their design, and along with this, doors such as entrance doors are also designed with various shapes. It is used.

Problems that the invention aims to solve However, most of the left and right vertical frames of conventional doors are formed with a rectangular cross section, and in this respect it is less innovative. In addition, most conventional doors are simply attached to the vertical frame of the entrance using hinges or pivot hinges (shaft hanging brackets), so when the door is opened or closed, it is structurally connected to the vertical frame on the fixed side of the door. There was a gap between the vertical frames, and there was a risk that the interior of the room could be completely seen through this area, or that a child could get their hands caught in the gap and cause an unexpected accident. There was also a risk of an accident occurring between the door tip and the vertical frame.

This invention was proposed in order to solve the above-mentioned conventional problems, and aims to provide a door that is highly novel and safe.

Means for Solving the Problem This invention forms a vertical stile on the rotating shaft side of a door attached to the doorway so that it can be rotated and opened and closed, and a vertical frame on the door end side of the doorway into a cylindrical shape, A reinforcing plate is attached to the vertical stile, the rotation axis of the vertical stile is located outside the wall surface around the doorway and the outer surface of the door, and an airtight member is attached to the side of the vertical stile, and the door is The above object is achieved by attaching it so that it can come into close contact with the vertical stile when closed.

Embodiment Hereinafter, this invention will be explained with reference to an embodiment illustrating the invention. The vertical stile 2 on the fixed side of the door 1 is formed in a cylindrical shape, bulges toward the outdoor side of the door 1, and extends in the vertical direction of the door 1. It is continuous.

Further, the vertical stile 2 is formed by bending a metal plate, and on the indoor side thereof, a recess 4 for fitting an airtight member 3, which will be described later, is formed continuously in the vertical direction of the vertical stile 2, and further, In the vertical stile 2, reinforcing plates 5 for preventing deformation are installed continuously in the vertical direction of the vertical stile 2 or at regular intervals in the vertical direction of the vertical stile 2.

Then, the door 1 is built inside the entrance 6, and the vertical stile 2
The fixed bearing 7 is attached to the upper and lower frames 9, 9a of the entrance/exit 6 by the fixed bearing 7 attached on the shaft of the material.
It is said that it is possible to open and close the door freely by using it as a rotating shaft.

Further, the door 1 is attached such that the rotation axis of the vertical stile 2 on the rotation axis side is located outside the wall surface around the doorway 6 and the outer surface of the door 1.

Therefore, the door 1 can be fully opened approximately 180 degrees until it touches the wall around the entrance 6. In addition, an airtight member 3 is fitted continuously in the vertical direction of the vertical stile 2 in the recess 4, and the airtight member 3 allows the space between the vertical stile 2 and the vertical frame 8 to be completely closed when the door 1 is closed. It is said that it is possible to perform a seal.

In this case, since the airtight member 3 is attached to the door side, the airtight member can be easily replaced by fully opening the door, even with the door attached.

In addition, since the gap between the vertical stile 2 of the door 3 and the vertical stile 8 of the entrance/exit 6 is always constant, the airtight member 2 is attached to the vertical frame 8.
When the airtight member 3 is attached to the door, the airtight member 3 is always in contact with the vertical frame 8 and is subject to significant wear, but by attaching it to the door, the airtight member 3 is much less likely to wear out.

In such a configuration, when opening and closing the door 1,
Since the vertical stile 2 rotates around the fixed bearing 7, it is not displaced at all. Therefore, the gap between the vertical stile 2 and the vertical frame 8 when the door 1 is opened and closed is always constant.

Furthermore, by forming the vertical frame 8a of the doorway 6 in a semicircular shape bulging toward the outdoor side, the left and right sides of the door 1 are balanced in terms of design.

Effects of the invention This invention has the following effects because it consists of the above structure.

Of the left and right vertical frames of the door, the vertical frame on the opening/closing axis side is formed in a cylindrical shape, and the vertical frame on the door end side is formed in a cylindrical shape, so it is highly innovative and allows for a variety of exterior designs. It can be greatly utilized in recent housing construction.

Since the door is installed so that it can be opened and closed by rotating around the axis of the fixed side stile, the gap between the fixed side stile of the door and the vertical frame of the entrance and exit is always constant when the door is opened and closed. . Therefore, there is no fear that the interior of the room will be completely visible from this part, or that a child will get their hand caught in this part and cause an unexpected accident, making it extremely safe.

By forming the vertical frame of the door and the vertical frame of the entrance/exit into a cylindrical shape, dangers caused by curved surfaces are prevented and safety is significantly improved.

In addition, a reinforcing plate is attached to the cylindrical stile on the rotating shaft side, so the stile on the rotating shaft side does not easily deform and can withstand repeated opening and closing. It has strong strength.

In addition, the door is installed so that the axis of the vertical stile on the side of the rotation axis of the door is located outside of the wall around the entrance and the outside of the door, so the door can be opened fully 180 degrees until it lines up with the wall around the entrance. can be done. Therefore, if you open the door fully 180 degrees, the door will not get in the way.

Furthermore, since the airtight member is attached to the side of the vertical stile so that the door can come into close contact with the vertical stile when the door is closed, the airtightness is also extremely high.
