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
-The conventional example shown in Publication No. 53507 is
As shown in the figure, since the spring 4' is attached to the arm 2 whose one end is fixed to the door body 3, the spring 4' is located on the rotation locus of the arm 2 fixed to the door body 3, and the spring 4' Arm 2 is fixed to door body 3
At the same time, the spring 4' is exposed to the outside, and there is a problem in that it is impossible to create a structure that prevents the spring 4' from being exposed.
Furthermore, in the case of a vertically long spring 4' as shown in Fig. 4, a large space is required for arranging the spring 4'.
There was a problem that the spring 4' portion could not be made compact. In addition, as another conventional example, for example, Japanese Patent Application Laid-Open No. 164591/1987 discloses a case in which a casing cylinder integral with an arm is integrally attached to a support of a garage door. It rotated together with the arm, and the casing cylinder could not be removed from the support.

[Object of the Invention] The present invention was invented in view of the above points, and its purpose is to attach the case that pivotally supports the base of the arm of the garage door to supports or walls depending on the situation at the site. By using a mainspring spring, the spring does not need to be located on the arm's rotation trajectory, and can be covered with a case so that it is not exposed to the outside. To provide a garage door that can be configured compactly.

[Disclosure of the Invention] In the garage door of the present invention, the base of the arm 2 is attached to the rotating shaft 1, the tip of the arm 2 is connected to the door body 3, and the garage door is closed with the door body 3 facing vertically. In addition, in a garage door that is opened with the door body 3 facing upward and horizontally, the rotary shaft 1 is rotatably supported in a case 5 for mounting on a support 16 or a mounting base such as a wall. A mainspring spring 4 is installed inside, and the mainspring spring 4 applies a spring force to the rotating shaft 1 to rotate the door body 3 in the opening direction, and has such a configuration. Thus, the above-mentioned object of the present invention has been achieved. That is, in the present invention,
By attaching the mainspring spring 4 to the rotating shaft 1,
The rotating shaft 1 can be directly rotated by the mainspring spring 4, and the spring is not located on the rotational trajectory of the arm 2, unlike conventional systems in which the arm 2 is rotated by a spring. The spring 4 can now be covered with a case or the like. In addition, by using the mainspring spring 4 to directly rotate the rotating shaft 1, the device can be made more compact, and the case 5 can of course be attached to the support 16 of the garage door. , walls and fences of buildings other than pillars 16,
Alternatively, it can be directly attached to other structures, and the mounting position of the case 5 can be selected depending on the situation at the site.

The present invention will be explained in detail below with reference to Examples. Case 5
A rotating shaft 1 is rotatably attached to the housing, and in the embodiment shown in the drawings, a case 5 is constructed by fitting a front case body 6 and a back case body 7 together. Case 5
There is a mainspring spring 4 inside. A rising piece 8 is provided at the outer peripheral end of the mainspring spring 4, a screw hole 9 is provided in this rising piece 8, and a long hole 10 is provided at a position shifted inward from the rising piece 8. A hole 11 is drilled in the side wall of the case 5, and a fixing screw 12 is inserted through the hole 11, and the fixing screw 12 is inserted into the elongated hole 10 of the mainspring spring 4.
The outer circumferential end of the mainspring spring 4 is fixed to the case 5 by inserting the main spring 4 through the nut 13 and screwing it into the nut 13. An insertion hole 14 is bored in the side wall of the case 5 facing the rising piece 8, and an adjusting screw 15 is inserted through the insertion hole 14 and screwed into the screw hole 9 of the rising piece 8. With the fixing screw 12 loosened, the adjustment screw 15 is rotated to adjust the spring strength of the mainspring spring 4, and when the adjustment is completed, the fixing screw 12 is tightened and fixed. The inner end of the mainspring spring 4 is attached to the rotating shaft 1. The base of an arm 2 is attached to the rotating shaft 1, and a door body 3 is attached to the tip of the arm 2. The mainspring spring 4 applies a spring force to the rotating shaft 1 to rotate the door body 3 in the opening direction.
The garage door configured as described above is closed with the door body 3 facing vertically, and opened with the door body 3 facing upwards and horizontally. However, there is a stopper for closing to prevent the door body 3 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 3 is oriented horizontally. A stopper for opening is provided to prevent rotation. In the embodiment shown in FIGS. 1 and 3, columns 16 are erected on both sides of the site where the garage will be used, and the case 5 is attached to the top of the column 16, so that the case 5 is a part of the column 16. Although a conventional embodiment is shown, the case 5 may be attached to a wall, fence, or other structure of a building without using the support 16. In other words, the rotating shaft 1 is mounted on the case 5 for mounting on a support 16 or a mounting base such as a wall.
Since the case 5 is rotatably supported and a mainspring spring 4 is installed inside the case 5, the case 5 can be attached not only to the support 16 of the garage door, but also to walls and fences of buildings other than the support 16. Alternatively, it can be directly attached to other structures; in either case, simply attaching the base of the arm 2 of the garage door to the rotating shaft 1 of the case 5 ensures rotational support of the arm 2 by the rotating shaft 1. The mounting position of the case 5 can be selected depending on the situation at the site.

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 by the solid line in FIG. 1, and the arm 2 hits the closing stopper and does not rotate any further. At this time, a force is acting on the mainspring spring 4 in the direction opposite to the ground, but the door body 3
Since the rotational moment applied to the rotating part due to the weight of the arm 2 and the like is greater than the rotational moment caused by the mainspring spring 4 that attempts to rotate the door body 3 in the closing direction, the closing state is maintained by hitting the closing stopper. It is something that exists. When you hold the door body 3 in your hand and push it upward, the door body 3 swings upward due to the pushing force and the spring force of the main spring 4.
It comes to a stop when it hits the stopper for opening at the set stop position. At this time, door body 3
Since the rotational moment that tries to rotate the door body 3 in the closing direction due to The door body 3 is designed not to rotate in the closing direction. Further, when closing the door body 3, the door body 3 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.

[Effects of the Invention] In the present invention, as described above, the base of the arm is attached to the rotating shaft, the tip of the arm is connected to the door body, and the door body is closed with the door body oriented vertically. For garage doors that are opened with the door facing upwards and horizontally, a mainspring spring is attached to the rotating shaft to rotate the door in the opening direction, so the rotating shaft can be directly rotated by the mainspring spring. As a result, unlike conventional models in which the arm is rotated by a spring, the spring is not positioned on the arm's rotation locus, and the mainspring can be used in cases such as cases without being hindered by the rotation of the arm. It is now possible to cover it with
Furthermore, in the present invention, since the rotating shaft is directly rotated using a mainspring spring, the spring portion can be arranged compactly near the rotating shaft. The rotating shaft is rotatably supported in a case for mounting on a mounting base such as a wall, and a mainspring spring is installed inside the case, so the course that supports the rotating shaft and has a mainspring inside can be used as a support. Depending on the situation at the site, you can choose how to attach it, such as by attaching it or directly attaching it to the wall or fence of a building.
