An arm 5' is installed between the end of the support member 4' and the lower part of the door body 3, and the end of the support member 4' is rotatably attached to the upper end of the column 2. A support means 6 was provided between the support 2 and the column 2. here 7
is a fence, 8 is a house, and 9 is a car. This garage door is closed by rotating the door body 3 so as to face vertically, and by rotating the door body 3 horizontally, as shown in FIGS. 1, 2, and 3. Although it is opened as shown in the imaginary line, when the door body 3 is opened, the lower end of the door body 3 protrudes toward the road side by a dimension a as shown in FIG. 3 compared to when the door body 3 is closed. In other words, when the door body 3 is closed, the door body 3
If a large gap S is created between the lower end of the GL and the ground (GL), there is a risk that dogs etc. may enter the GL, so a height above a certain level is required. Therefore, when the door body 3 is opened, the door body 3 protrudes by the dimension a, which obstructs the passage of automobiles and the like traveling on the road.

(Object of the Invention) The present invention has been made in view of the points described above, and the object of the present invention is to keep the lower end of the door body closer to the road than the position of the door when it is closed even when the door body is opened. To provide a garage door that does not protrude or obstruct road traffic.

(Disclosure of the Invention) The garage door of the present invention has one end of a support member 4 connected to both sides of the upper part of the door body 3, and one end of an arm 5 connected to both sides of the lower part of the door body 3, and the other end of the support member 4 and the arm 5. Rotatably attach the other end to the top of the support column 2,
In a garage door that is closed when the door body 3 is rotated to face the vertical direction and opened when the door body 3 is rotated to face the horizontal direction, one end of the support member 4 is attached to the door body 3. A slide plate 21 provided on both sides of the lower part of the door body 3 is provided with a vertically long slide groove 23, and one end of the arm 5 is connected to the slide groove 23 so as to be slidable up and down. A stopper 17 for closing, which the arm 5 hits when the body 3 is closed so as to face vertically, is provided on the upper part of the column 2, and when the door body 3 is opened so as to face horizontally, the support member 4 is moved from the vertical position. An opening stopper 18 is provided on the upper part of the door body 3, and the support member 4 hits when the lower end of the door body 3 is located on the vertical line where the door body 3 is located when closed while being rotated by a predetermined angle in the opening direction. Gas spring 1 inside 2
2 inside the gas spring 12 and one end of the gas spring 12 is attached to the support 2.
The gas spring 12 is rotatably attached to the fixing metal fitting 13 inside, and the shaft 10 fixed to the other end of the support member 4 is rotatably attached to the upper part of the support column 2. The other end is rotatably connected, and the drawbacks of the conventional example are solved by configuring it as described above.

The present invention will be explained in detail below with reference to Examples. Reference numeral 2 is a support with a hollow interior, and is erected so as to face each other. 3 is a door body formed in a grid shape. Reference numeral 4 denotes a support member, one end of which is rotatably connected to mounting brackets 19 on both sides of the upper end of the door body 3 via a shaft 20. Slide plates 21 are attached to both sides of the lower part of the door body 3, and a shaft 22 is attached to a vertically long slide groove 23 provided in the slide plate 21 so as to be slidable up and down. It is connected to a shaft 22. Bearing 1 is installed at the top of column 2.
4, the shaft 10 is rotatably mounted, and the shaft 1
The other end of the support member 4 is fixed to the support part 11 that protrudes from the support part 11, and the other end of the arm 5 is rotatably attached to the support part 11. A gas spring 12 is installed inside the column 2, and one end of the gas spring 12 is rotatably attached to a fixture 13. axis 1
0, one end of a cam plate 15 is fixed, and the other end of the gas spring 12 is rotatably connected to the other end of the cam plate 15. A stopper 17 for closing and a stopper 18 for opening are provided at the upper part of the column 2.

Next, the operation of the garage door configured as described above will be explained. The state in which the door body 3 faces vertically as shown in FIGS. 7 and 9a is the closed state, and the arm 5
The shaft 22 contacts the closing stopper 17 to prevent further downward rotation, and the shaft 22 is located at the upper end of the slide groove 23. At this time, a force is acting on the gas spring 12 in the direction opposite to the ground GL, but when the door is closed, the door body 3
The closed state is maintained because the rotational moment exerted on the rotating part due to the weight of the valve is large. When you hold the door body 3 and push it up, the force pushing up the door body 3 and the gas spring 12 are generated as shown in FIG. 9b.
The support member 4 swings upward together with the door body 3 due to the force. At this time, the door body 3 rotates under its own weight and moves upward while hanging vertically until the support member 4 comes to the position of the set angle α. Meanwhile, the shaft 2 at the tip of arm 5
2 moves along the slide groove 23 to a stopping position at the lower end of the slide groove 23, as shown in FIG. 9c. Thereafter, the door body 3, the support member 4, and the arm 5 continue to swing as shown in FIG.
As shown in Fig. 9e, stopper 1 for opening is shown.
The support member 4 hits the 8 and stops. At this time, the force of the gas spring 12 acts in the opposite direction to the ground GL to push up the cam plate 15, and the door body 3 will not descend unless a downward force is applied. Further, in this open state, the lower end of the door body 3 is located on the vertical line l when the door body 3 is in the closed state. In other words, the support material 4
The lower end of the door body 3 is positioned on the vertical line l by rotating the door body 3 by α more than 90 degrees and sliding the door body 3 toward the support column 2 by the slide groove 23.
When closing the door body 3, hold the door body 3 and pull it up, and the stopper 1 for closing will move in the order of Fig. 9 e, Fig. 9 d, Fig. 9 c, Fig. 9 b, and Fig. 9 a.
The arm 5 hits 7 and stops at that position.

(Effects of the Invention) As described above, the present invention rotatably connects one end of the support member to both sides of the upper part of the door body, opens the door body so as to face in the horizontal direction, and moves the support member from a vertical state to a predetermined opening direction. There is a stopper on the top of the door that rotates the angle and hits the support when the lower end of the door is positioned on the vertical line where the door is when closed, so the door can be turned laterally. When opened, the supporting member rotates by a predetermined angle in the opening direction from the vertical position and is stopped by a stopper for opening,
The lower end of the door body does not protrude toward the road when opened and does not obstruct road traffic, and the position of the lower end when the door body is closed is the same as the position of the lower end when the door body is open. During construction, it is easy to position with respect to the road, and construction is easy.
In addition, long vertical slide grooves are provided on the slide plates provided on both sides of the lower part of the door body, and one end of the arm is connected to the slide groove so that it can slide up and down, so that when the door body is opened, the support material can be moved from a vertical position. Even if the door rotates at a predetermined angle in the opening direction, one end of the arm slides against the slide groove, making the door approximately horizontal, eliminating the problem of the door being too high when opened. (If one end of the arm is simply connected to the door body, the bottom end of the door body will be higher than the top end of the door body when it is opened). One end of the gas spring is rotatably attached to a fixing metal fitting inside the support, the shaft fixed to the other end of the supporting member is rotatably attached to the top of the support, and the other end of the gas spring is attached to a cam plate fixed to the shaft. Since they are rotatably connected, the gas spring acts both when opening and closing the door body, which has the advantage of allowing the door body to be opened lightly and loosely closed when closing the door body. .
