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] Flip-up garage doors have been around since 1977.
It is known from Publication No. 53507. This special public service 1977
In the conventional example shown in Publication No. 53507, a post is erected on the ground of the garage, the base of the arm is rotatably attached to the post, a door body is attached to the other end of the arm, and the arm is attached to the post. By rotating, the door body can be closed in a vertical position, or opened in a horizontal position. However, in the conventional example described above, there was a problem in that the pillars protruding from the ground were unsightly. For this reason, it is conceivable to drive an anchor bolt into a concrete wall such as a block wall or concrete wall, and use this anchor bolt to attach the base of the arm in a rotatable manner. Simply driving anchor bolts into the wall of the system was not able to reliably support the arm connected to the heavy door body. In particular, concrete walls such as block walls and concrete walls into which anchor bolts are driven are used as fences, so the structural strength of the wall surface is not very strong, and if the wall surface strength is weak, there is a problem that it will collapse. (For example, Japanese Patent Application Publication No. 1983-
(See Publication No. 91282). Therefore, as another conventional example,
For example, Japanese Utility Model Application Publication No. 54-66636 discloses a structure in which a support is embedded in the wall and the base of the arm is rotatably supported by the support, but in this case, the installation height of the door body is fixed. The drawback was that the height could not be adjusted to suit the site. Furthermore, as another conventional example, Japanese Patent Application Laid-Open No. 164566/1983 discloses a system in which the base of the arm is attached to any position above or below a mesh plate attached to the side of a column, but this conventional example Even if the installation height of the grid panel could be adjusted, the entire mesh board was exposed to the outside of the column, resulting in a disadvantage in that the appearance would be impaired.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to prevent the pillar from being exposed, and to support the arm reliably.
Furthermore, we provide a garage door that can also strengthen concrete walls.

[Disclosure of the Invention] The garage door of the present invention is a garage door that is closed with the door body 1 facing vertically and opened with the door body 1 facing upward in the horizontal direction.
A support column 3 for supporting the garage door is embedded in a concrete wall 2, one side of the column 3 embedded in the wall 2 is exposed to the outside, and a plurality of attachment parts 6 are provided in the vertical direction on this exposed part, and a plurality of attachment parts 6 are provided in the vertical direction. The base of the arm 4 is rotatably attached to the attachment part 6 of the arm 4, the tip of the arm 4 is connected to the door body 1, and the exposed parts other than the attachment part 6 to which the arm 4 is attached are covered with a cover plate 10. By adopting such a configuration, the above-mentioned object of the present invention is achieved. In other words, in the present invention, by embedding the support 3 in the concrete wall 2, the support 3 is not exposed in a protruding state,
In addition, by supporting the arm 4 on the pillar 3 embedded in the wall 2, the arm 4 can be supported reliably, and the wall 2 can also be reinforced by the pillar 3. Furthermore, by covering the exposed parts other than the mounting part 6 to which the arm 4 is attached with the cover plate 10, the structure allows the installation of the door body 1 to be adjusted up and down in height, and yet can be constructed with a good appearance. be.

The present invention will be explained in detail below with reference to Examples. A pillar 3 for supporting the garage door is embedded in a concrete wall 2 made of block or concrete, which constitutes the side part of the garage. In the embodiment shown in the drawings, this column 3 is a U-shaped steel with a lip, and the lip portion 5 of the column 3 is substantially flush with the wall 2, and the lip portion 5 faces the outside. A plurality of mounting screw holes 6 are bored in the lip portion 5 at the top and bottom. A plurality of mounting screw holes 6 provided above and below serve as a plurality of mounting portions in the vertical direction for mounting the arm 4. The lower part of the pillar 3 is further buried in the ground. A cover 7 is provided at the upper end of the column 3 as shown in FIG. 4 to prevent concrete from flowing into the column 3 when the column 3 is buried in the concrete wall 2. Lip part 5 of pillar 3
A mounting plate 8 is mounted with screws 9 using mounting screw holes 6 of arbitrary height provided in the mounting plate. The base of the arm 4 is rotatably attached to the mounting plate 8. A door body 1 is attached to the tip of the arm 4. Here, the height of the mounting plate 8 is arbitrarily selected according to the mounting height of the arm 4, and the cover plate 10 is attached with screws 9 to the parts other than the part where the mounting plate 8 is attached. The gap between the lip portions 5 is hidden. The arm 4 is attached to the attachment plate 8 as shown in FIGS. 5, 6, and 7, for example. In this embodiment, an annular protrusion 11 is provided on the mounting plate 8,
A locking protrusion 12 is provided on the outer periphery of the annular protrusion 11, and a shaft portion 13 is protruded from the center of the portion of the mounting plate 8 surrounded by the annular protrusion 11. The shaft portion 13 is provided with a notch portion 19 . A horizontal cylinder part 15 is fixed to the base of the arm 4, and one side of the horizontal cylinder part 15 is open and the other side is closed. Horizontal cylinder part 15
A mainspring spring mounting part 16 is provided on the inner peripheral surface of the mainspring spring mounting part 16, and the outer end part of a mainspring spring 17 housed inside the horizontal cylinder part 15 is mounted to the mainspring spring mounting part 16. A locked portion 18 is provided at the inner edge of the side opening of the horizontal cylinder portion 15 . However, the inner end of the mainspring spring 17 is inserted into the notch 1 of the shaft portion 13.
9 and the locked part 1 of the horizontal cylinder part 15.
8 is locked to the locking protrusion 12 of the annular protrusion 11, and the horizontal cylinder part 15 is rotatably attached to the annular protrusion 11. Therefore, the mainspring spring 17 housed inside the horizontal cylinder part 15 is attached to the door body 1 in the horizontal cylinder part 15.
A spring force is applied to rotate the door in the opening direction.

The garage door configured as described above is closed with the door body 1 facing vertically and opened with the door body 1 facing upward in the horizontal direction. However, there is a stopper for closing to prevent the door body 1 from rotating further in the closing direction when it is oriented vertically, and a stopper for preventing it from rotating further in the opening direction when the door body 1 is oriented horizontally. A stopper for opening is provided to prevent rotation.

Next, the operation of the garage door constructed as described above will be explained. The closed state is when the door body 1 faces vertically as shown by the solid line in FIG. 1b, and the arm 4 hits the closing stopper and is prevented from rotating any further. At this time, a force is acting on the mainspring spring 17 in the direction opposite to the ground, but the rotational moment applied to the rotating parts due to the weight of the door body 1, arm 4, etc. causes the mainspring spring 17 to rotate the door body 1 in the closing direction. Since the torque is greater than the rotational moment, the closed state is maintained by the closing stopper. When you hold the door body 1 in your hand and push it upward, the door body 1 swings upward due to the pushing force and the spring force of the main spring 17, and stops at the set stop position when it hits the opening stopper. I'm starting to do that. At this time, since the rotational moment by the door body 1 etc. that tries to rotate the door body 1 in the closing direction is reduced, the spring force of the mainspring spring 17 is exceeded, and the mainspring spring 1
The door body 1 does not rotate in the closing direction unless a rotational force is applied in the closing direction against the force 7. When closing the door body 1, the door body 1 is held in the hand and rotated in the closing direction against the spring force of the mainspring spring 4, so that it closes and stops against the closing stopper.

In the above embodiment, an example of a U-shaped steel with a lip is shown as the support 3, but a steel pipe with a hollow interior may be used as the support 3.

By the way, in the above embodiment, the mainspring spring 17
Although an embodiment using spring means has been shown, other spring means may be used. In this case, for example, FIG.
As shown in FIG.
A fixed shaft 21 is provided at the base of the arm 4, the fixed shaft 21 is pivotally supported by a bearing part 20, an arm 22 is protruded from a portion of the fixed shaft 21 located inside the pillar 3, and a fixed shaft 21 is provided at the base of the arm 4. One end of the spring 24 may be attached to the lower part of the support column 3, and the other end of the spring 24 may be attached to the lower part of the support column 3. Here, instead of the spring 24, a gas spring may be used.

Alternatively, an electric drive device may be disposed within the support column 3, and the arm may be rotated by the electric drive device.

When a U-shaped steel member with a lip is used as the support 3, a spring or an electric drive device can be placed inside the support 3, and during maintenance and inspection, the cover plate 1
It is a good idea to remove the 0 and open the inside for maintenance and inspection. This cover plate 10 covers the exposed parts other than the attachment part 6 to which the arm 4 is attached, and has a structure that allows the installation of the door body 1 to be adjusted up and down in height, while also being able to be constructed with a good appearance. It is something. When a steel pipe is used as the support 3, an opening to the outside is provided in a part of the steel pipe,
It is recommended to detachably attach a lid to this opening and remove the lid to perform internal maintenance and inspection.

[Effects of the invention] As described above, in the present invention, a column for supporting a garage door is embedded in a concrete wall, and a support column for supporting a garage door embedded in the wall is attached to the exposed part of one side in the vertical direction. The base of the arm is rotatably attached to any vertical attachment point, and the exposed parts other than the attachment point to which the arm is attached are covered with a cover plate, so that the support does not rest on the ground. It has a good appearance without being exposed protruding from the concrete wall, and by supporting the arm with a pillar buried in the concrete wall, the arm can be supported reliably and the wall can be reinforced with the pillar. In addition, one side of the pillar buried in the wall is exposed to the outside, a plurality of attachment parts are provided in the vertical direction on this exposed part, and the base of the arm is rotatably attached to any attachment part in the vertical direction. Since the tip of the arm is connected to the door body, the base of the arm can be rotatably attached to the attachment point at any position in the vertical direction depending on the site conditions, allowing the installation height of the door body to be adjusted to suit the site. It can be adjusted accordingly.
