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 3 and 4, pillars 2' are erected inside the gate post 1, and support members are placed from both sides of the upper end of the lattice-shaped door body 3 at right angles to the door body 3. 4
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 connected to the support post 2'.
It is rotatably attached to the upper end of the arm 5 and the support column 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 that it faces vertically, and by rotating the door body 3 so that it faces horizontally above the support column 2', as shown in FIGS. It is designed to open as shown in the imaginary lines in Figures 2 and 3, but when it is closed, the support member 4 becomes cantilevered in the horizontal direction, and the support member 4 is weak against loads from above, and the door is closed. The body 3 and support material 4 are easily deformed. In other words, when the door body 3 is opened, the door body 3 must be raised to a height that allows cars and people to pass through, and the support material 4 requires an appropriate length, and the longer the support material 4 is, the weaker the strength becomes. Become.

[Purpose of the invention]

The present invention has been made in view of the above points, and an object of the present invention is that when the door body is closed, the supporting member can be supported by the horizontal piece of the column, and the supporting member and the door body are deformed. Our aim is to provide garage doors that are free from damage.

[Disclosure of the 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 2 are attached to the upper part of the pillars 2 that are erected to face each other. In a garage door that is rotatably mounted and closed when the door body 3 is rotated to face in the vertical direction, and opened when the door body is rotated to face the horizontal direction on the support 2, The support 2 is formed into an inverted L shape, and the end of the support member 4 is rotatably attached to the free end of the horizontal piece 2a of the support 2, and the horizontal piece 2a of the support 2 is attached when the door 3 is closed. This is a supporting part of the supporting member 4, 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 denotes a substantially inverted L-shaped support consisting of a horizontal piece 2a and a vertical piece 2b, which are 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. The horizontal piece 2a of the column 2 and the support member 4 have approximately the same length, and a shaft 10 is attached to the free end of the horizontal piece 2a.
The end portion of the support member 4 is rotatably mounted. A stopper 11 is provided vertically at the free end of the horizontal piece 2a. A spring storage section 12 is provided on the horizontal piece 2a.
is recessed in the longitudinal direction, and the gas spring 13
One end is rotatably attached to the vertical piece 2b side of the horizontal piece 2a, and the other end of the gas spring 13 is attached to the support member 4.
It is rotatably connected to the mounting plate 14 of.

Next, the operation of the garage door constructed as described above will be explained. As shown in Fig. 6, the closed state is when the door body 3 faces vertically, and the support member 4 rests on the horizontal piece 2a of the support column 2, preventing it from rotating downward any further. At the same time, the support member 4 is held so as not to receive a load. At this time, gas spring 1
3 acts in the direction of closing the door body 3 and maintains the closed state. If you hold any part of the door body 3 and push it upward, the door body 3 will swing upward due to the pushing force and the force of the gas spring 13, and will swing about 90 degrees until the support member 4 hits the stopper 11. The door body 3 faces laterally above the support column 2. In this case, the action of the gas spring 13 makes its rocking smooth and reduces the operating force. Further, when the door body 3 is open, the support member 4 is pressed against the stopper 11 by the gas spring 13, so the door body 3 will not fall unless force is applied in the direction of closing the door body 3. Further, when the door body 3 is opened, the lower end of the door body 3 is located on the vertical line when the door body 3 is closed, and the lower end of the door body 3 protrudes toward the road side and does not obstruct road traffic. Further, when closing the door body 3, the door body 3 is held and pulled up, and the support member 4 rests on the horizontal piece 2a of the support column 2 and stops. At this time, the gas spring 13 is stored in the spring storage portion 12.

〔Effect of the invention〕

In the present invention, as described above, the support is formed into a substantially L-shape,
The end of the support member is rotatably attached to the free end of the horizontal piece of the support, and the horizontal piece of the support serves as a support for the support when the door body is in the closed state, so the door body can be oriented vertically. When the gate is closed, the supporting member rests on the horizontal piece of the support column, and there is no risk that the supporting member or the door body will be deformed by strong loads from above.
