Eliminate any gaps that appear and create a beautiful appearance. [Constitution] In a door 1 in which a gravity hinge 6 is installed on one side so that it can be swung up and rotated to automatically close from an open state by the load of the door itself, a door upper surface portion 8 is formed horizontally, and a door upper surface is formed. While the distance L between the part 8 and the upper frame 2 is set to be equal to or larger than the maximum width of moving the door 5 in the vertical direction, the space (distance R) between the upper end 9a of the side plate 9 and the lower surface 2a of the upper frame 2 is excessive. So that there is no gap. In addition, the notch 11 is formed at the upper end one side corner of the side plate member 9 so that the upper frame 2 is not contacted even when the door 5 is completely opened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door having a door supported so as to automatically close from an open state.

[0002]

2. Description of the Related Art Conventionally, various means have been used as means for supporting a door so as to be automatically closed from an open state. Among them, a means for attaching the so-called door closer 50 to the upper frame 52 and the upper frame 53 above the door 51 as shown in FIG. 10 and a structure similar to the door closer as shown in FIG. Floor hinge 6 stored in body 60
The means for suspending the shaft at 1 was common.

[0003]

However, both of the means for mounting the door closer and the means for suspending the floor hinge by the floor hinge, these switches will largely protrude to the inside or outside. However, it not only spoils the aesthetic appearance, but also may be dangerous depending on the height of the switch. In addition, when opening the door, a large force that exceeds the resistance of the switches to close them is required, which is difficult.

On the other hand, it was possible to store and install these switches inside the door, but the complicated structure of the door not only makes it difficult to process, but also requires an excellent professional craftsman. However, there were problems in terms of technology, personnel, and cost.

Therefore, in view of the above problems, the present invention automatically closes the door from the open state, yet the structure is simple and easy to manufacture, and the manufacturing cost can be kept low. The aim is to provide a door that is aesthetically pleasing.

[0006]

In order to solve the above problems, in the present invention, first, in order to simplify the door structure, an upper support member is provided as a means for supporting the door so as to be automatically closed from an open state. And a lower bearing member, the contact surfaces of both of which are formed in an inclined shape, and the upper support member slides on the inclined contact surface as the door opens, so that the door swings and rotates to rotate and rotate the door. When pivotally supporting a hanging metal fitting such as a hinge, we decided to adopt a means such as a means to incline the axis of the upper and lower hanging metal fittings so that the door can be rotated, opened and closed, and automatically closed by its own weight. Next, in the present invention, in order to adjust the aesthetic appearance, the gap between the door and the upper frame is configured to be eliminated in appearance, while preventing the door from contacting the upper frame when opening and closing the door. I configured it.

That is, the door of the present invention is provided with a door frame having an upper frame and a switch on one side, and is rotated around the one side to move upward and open, and the door is automatically opened by its own weight. A door that is supported so as to close in a closed manner, and at least the maximum vertical movement width of the door is at least between the upper end closing side end of the door and the upper frame, while the upper end opening side of the door and the upper frame are It has a configuration in which the two are close to each other. Further, a cutout may be formed in the vicinity of the shaft support portion of the door upper end open side end or the upper frame open side end in the above door structure.

[0008]

According to the door of the present invention, as the door is opened by hand, the door turns and rotates, and vertically moves. Therefore, when the hand is released in the open state, the door is automatically closed by its own weight. On the other hand, since at least the upper end closing side end of the door and the upper frame are formed to have a maximum vertical movement width of the door or more, it is possible to open and close the upper end of the door without contacting the upper frame. Further, when the door is closed, the door is closed without leaving an extra gap between the upper end of the door and the upper frame, so that the appearance is not spoiled.

Further, if a notch is formed at the upper end of the door or at one side of the upper frame, the upper frame also comes into contact with the vicinity of the pivotal support at the upper end of the door that remains under the upper frame to the end when the door is rotated and rotated. It can be easily opened and closed to prevent it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the door 1 of the present invention includes a door frame 4 composed of an upper frame 2 and a vertical frame 3, a gravity hinge 6 installed near the lower end of one side of the door and an upper end near the one side of the door. The door 5 is hung from the center or taken out by an upper hinge 7 installed vertically above the gravity hinge 6. The door 5 is, as shown in FIG.
Is completely stored in the upper frame 2 in a closed state, while rotating and rising about the axis between the gravity hinge 6 and the upper hinge 7,
From the open state, the door automatically closes due to its own load.

Here, the gravity hinge 6 is shown in FIG.
As shown in, the upper support member 6a and the lower bearing member 6b
And a contact surface 6c formed in a slanted shape. The upper support member 6a is embedded and fixed in the door 5, and the lower bearing member 6b is also embedded and fixed in the floor surface A. As the door 5 is opened, the upper support member 6a slides on the inclined contact surface 6c. However, the door 5 is adapted to rotate spirally. On the other hand, as shown in FIG. 3, the upper hinge 7 is a hinge including an upper bearing member 7b having a cylindrical portion 7a and a lower support member 7d having a cylindrical shaft 7c corresponding to the cylindrical portion 7a. The upper bearing member 7b is embedded and fixed in the upper frame 2, and the lower support member 7d is embedded and fixed in the door 5. In response to the movement of the door 5 in the vertical direction by the gravity hinge 6, , The cylindrical shaft 7 inside the cylindrical portion 7a
c can move up and down.

As shown in FIG. 4, the door 1 has a door upper surface 8 formed horizontally, and the distance L between the door upper surface 8 and the lower surface 2a of the upper frame 2 is the maximum vertical movement width of the door 5. While the door 5 is mounted so that the height is H or more, the door main body 10 is formed so that the door-opening side surface plate member 9 projects upward from the door upper surface portion 8 by an appropriate width.
Mounted on the door, or the surface plate of the door body 10 is formed upright,
The upper end 9a of the side surface plate member 9 and the lower surface 2a of the upper frame 2 are prevented from forming an extra gap. Here, the distance between the upper end 9a and the lower surface 2a is referred to as a distance R.

The maximum vertical movement width H is a width in which the door 5 moves in the vertical direction from the closed state to the maximum open state. This maximum vertical movement width H is mainly due to the gravity hinge 6
Determined by the structure of. Door upper surface portion 8 and upper frame 2 lower surface 2
The distance L from a is preferably formed to be about 10 to 20 mm. On the other hand, it is preferable that the distance R between the upper end 9a of the side plate member 9 and the lower surface 2a of the upper frame 2 is set to about 5 to 7 mm.

As shown in FIG. 1, a notch 11 is formed at one corner of the door opening side plate member 9.

Since the upper end 9a of the notch 11, which is in the middle of opening the door 5 and in the open state, that is, the upper end 9a near the pivotal support of the side plate 9, gradually rises and contacts the upper frame 2, The contactable portion is formed as a notch. That is, the size of the notch 11 is determined by the structure of the gravity hinge 6, the distance R, and the thickness of the side surface plate member 9. The notch 11 may be formed in a rectangular shape when viewed from the front as shown in FIG. 1A, or as shown in FIG. It may be formed in a slanting triangular shape, or, although not shown, the slanted oblique side shaft support may be formed horizontally or may be formed in a fan shape.

By forming the door 1 in this way,
When the door 5 is closed, the door 5 does not come out from the upper frame 2 to the open side, and an extra gap is not created between the door 5 and the upper frame 2 so that the appearance is beautiful. There is no loss. On the other hand, by setting the distance L between the door upper surface portion 8 and the upper frame 2 to be the maximum vertical movement width H or more, the door upper surface portion 8 does not contact the upper frame 2 on the other side portion of the door, as shown in FIG. The door 5 can be opened and closed as described above. Further, by forming the notch 11 at the upper end corner on one side of the door opening side face plate member 9, even when the door 5 is opened, even if it is on the one side of the door upper end located below the upper frame 2. The door 5 can be opened and closed so as not to contact the upper frame 2.

The upper frame 2 in the structure of the door 1 is shown in FIG.
As shown in FIG. 7, the door stop 13 may be formed to have a length longer than that of a general upper frame, and the protruding portions 14 and 15 protruding on both sides of the door stop 13 may be formed at the same height. However, as shown in FIG. 6, the overhanging portion 14 of the doorstop 13 is formed at a position higher than the overhanging portion 15 on the opposite side, so that the length of the doorstop 13 on the doorstop side is increased. You may make it apparently long.

As shown in FIG. 7, the notch 11 is formed in the lower corner near one side end of the upper frame 2 instead of being formed in the upper end corner at one side of the door open side plate member 9. Cutout 12
May be formed. By forming the cutout portion 12 in this manner, the same effect as when the cutout portion 11 is formed can be obtained. Further, as shown in FIG. 8, when the door 5 is housed so that the door opening side face plate member 9 goes out from the upper frame 2 to the opening side in the state where the door 5 is closed, the cutouts 11 to 12 are provided. It need not be formed.

Although not shown, instead of suspending the shaft by the gravity hinge 6 and the upper hinge 7, a hanging metal fitting such as a hinge is attached and pivotally supported so that the shaft center is inclined vertically on one side of the door. May be.

9 (A) and 9 (B) show an upper sectional structure of the door 20 and the door 30 as an embodiment of a structure different from that of the door 1.

In the door 20 shown in FIG. 9A, a horizontal plane 23 is formed from the door upper end closed side end 21 to the door upper end open side end 22 as a horizontal plane 23, and the horizontal plane 23 and the upper frame. The distance from the lower surface 24a of 24 is the maximum vertical movement width H
On the other hand, the opening side is the upper end of the door and the end 22 on the opening side.
It is formed as an ascending slope 25 toward the front end of the door and the lower end 24a of the upper frame 24 is formed to have a slight distance. Further, the door 30 shown in FIG. 9B has a door upper end closing side end 31 and a lower surface 32 of the upper frame 32.
The distance from a is equal to or larger than the maximum vertical movement width H, while the door upper end closed side end 31 to the door upper end open side end 33 is an upward slope 34 directed toward the door upper end open side end 33. Form the door upper end open side end 33, the lower surface 3 of the upper frame 32
The distance between 2a is formed slightly.

That is, in addition to the structure of the door 1 described above, at least the space between the upper end closed side end of the door and the upper frame is formed to be larger than the maximum vertical movement width of the door, while the upper end open side end of the door and the upper frame are formed. Even with a slight distance from the frame, the same effect as the door 1 can be obtained.
