Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a garage door provided at the entrance/exit of a garage.

[Background technology]

For conventional garage doors, see Figures 1 and 2.
As shown in Figures 1, 3, and 4, pillars 2 are erected inside the gatepost 1, and support members 4 are placed from both sides of the upper end of the lattice-shaped door body 3 so as to be perpendicular to the door body 3. 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 support post 2. A support means 6 was provided between the two. 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. As shown in the imaginary line, it is opened, but the vertical width when the door body 3 faces vertically and is in the closed state is the vertical width from the end of the support member 4 on the door body 3 side to the part attached to the support post 2. Since it is longer than the length, 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, if a large gap S is created between the lower end of the door body 3 and the ground GL, there is a risk that dogs or the like may enter the door body 3, so the height must be above a certain level. 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. Moreover, if an attempt is made to prevent this, there is a drawback that the installation must be recessed into the site by the dimension a, which requires an extra site area.

[Purpose of invention]

The present invention was developed in view of the above points, and the purpose of the present invention is to maintain the door body in an inclined state when opened, so that the amount of protrusion toward the road side is reduced compared to the conventional method. To provide a garage door whose door body does not obstruct road traffic and does not require extra site area for opening and closing.

[Disclosure of invention]

In the garage door of the present invention, support members 4 are provided protruding from both sides of the upper end of the door body 3 so as to be perpendicular to the door body 3, and both ends of the support members 4 are attached to the upper ends of the pillars 2 that are erected to face each other. In a garage door that is rotatably mounted and is closed when the door body 3 is rotated so as to face in the vertical direction, and opened when the door body 3 is rotated so that the door body 3 is faced in the horizontal direction, the door body 3 Support material 4
The length is longer than the length from the end of the door body 3 side to the part attached to the support post 2, and the door body 3 is inclined so that the lower end of the door body 3 is located above the upper end of the door body 3 when the door body 3 is open. The device is designed to be held in the same state, 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 integrally fixed to both sides of the upper end of the door body 3, and the support member 4 is attached perpendicularly to the door body 3. Reference numeral 5 denotes an arm, one end of which is fixed to the lower part of the door body 3. Pillar 2
A shaft 10 is rotatably mounted on the upper part of the arm by a bearing 14, and the other end of the support member 4 is integrally fixed to a support portion 11 protruding from the shaft 10, and the other end of the arm 5 is rotated by the support portion 11. It can be worn freely. A gas spring 12 is installed inside the pillar 2.
One end of the gas spring 12 is rotatably attached to a fixture 13. One end of a cam plate 15 is fixed to the shaft 10, and the other end of the gas spring 12 is rotatably connected to the other end of the cam plate 15.
A stopper 18 for closing and a stopper 17 for opening are provided on the upper part of the column 2.

Next, the operation of the garage door constructed as described above will be explained. The closed state is when the door body 3 faces vertically as shown in FIG. 7, and the arm 5 hits the closing stopper 18 to prevent further rotation. At this time, a force is acting on the gas spring 12 in the direction opposite to the ground GL, but
When closed, the closed state is maintained because the rotational moment exerted on the rotating parts due to the weight of the door body 3, support member 4, etc. is large. When one of the door bodies 3 is held and pushed upward, the door body 3 swings upward due to the pushing force and the force of the gas spring 12, and at the set stop position (90°+α), the opening stopper 17 is moved.
The support member 4 hits 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. In this open state, the door body 3 rotates at an angle of 90° + α and tilts so that the lower end of the door body 3 is above the upper end, and the lower end of the door body 3 is moved from the closed position of the door body 3 to the support. Located on the 2nd side,
Do not protrude to the road side. Further, when closing the door body 3, the door body 3 is held and pulled down, and the arm 5 hits the closing stopper 18 and stops at that position. In the above embodiment, the swing range of the door body 3 is restricted by a stopper 18 for closing the support member 4 or the arm 5.
Although this was done by hitting the opening stopper 17, the cam plate 15 may also be used to restrict the opening.

[Effect of idea]

As described above, in the present invention, when the door body is opened, it is held in an inclined state so that the bottom end of the door body is located above the top end of the door body, so when the door body is opened, it is held in an inclined state with respect to the horizontal plane. The projecting length toward the road side is reduced by tilting, the door body does not protrude into the road and obstruct road traffic, and the amount of protrusion of the door body can be reduced even if the support is not installed inside the site. It is possible to reduce the amount of noise and does not require extra land for opening and closing the door body.
