Description

[Detailed description of the invention] [Technique? FIELD OF THE INVENTION The present invention relates to a garage installed at the entrance/exit of a lane.

[Back i technology] Traditionally, the flip-up type brake 7 was developed in 1986-535.
It is known from the f publication in 2007. This special public service in 1977-
The conventional example shown in Japanese Patent No. 53507 has a spring 4 attached to an arm 2 whose one end is fixed to the door body 3, as shown in FIG.
Since the spring 4' is attached 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' is exposed to the outside together with the arm 2 fixed to the door body 3. There was a problem that it was not possible to create a structure that would not expose ′. Furthermore, as shown in Fig. 4, there are springs 4' arranged vertically.
In this case, a large space is required to place the spring 4',
There was a problem that the spring 4' portion could not be made compact.

[Objective of the Invention 1 The present invention was invented in view of the above points, and its purpose is to use a mainspring spring to
To provide a garage door which does not require a spring to be located on the rotation locus of an arm, can be covered with a case or the like so as not to be exposed to the outside, and 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, and the tip of the arm 2 is connected to the door body 3.
A play in which the door is closed with the door facing vertically and opened with the door body 3 facing upward and horizontally: / At the door, turn the door body 3 in the opening direction in times @ Tsumugi 1! It is constructed by attaching a mainspring spring 4 that is intended to be FJJ, and by having such a configuration, the above-mentioned object of the present invention is achieved. That is, in the present invention, by attaching the spring 4 to the rotation shaft 1, the rotation shaft 1 can be directly rotated by the spring 4, and unlike the conventional method, the arm 2 can be rotated directly by the spring 4. The spring is not located on the rotation locus of the arm 2 like in a rotating device, and the mainspring spring 4 can be covered with a case or the like without being disturbed by the rotation of the arm 2.

By using the mainspring h = t to directly rotate the Kaiden Tsumugi 1, it has become possible to make it more compact.

[Below] ζ The present invention will be explained in detail with reference to Examples. A rotating shaft 1 is rotatably attached to a case 5, and in the embodiment shown in the drawings, the case 5 is constructed by fitting a front case body 6 and a back case body 7 together. Inside the case 5 (this is where the mainspring spring 4 is installed internally. A rising piece 8 is provided at the outer peripheral end of the mainspring spring 4, and a screw hole 9 is provided in this rising piece 8. , a stool 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 the fixing screw 1; 12 is inserted through this hole 11, and the fixing screw 12 is inserted through the support 10 of the mainspring spring 4, and then screwed into the nut 13 to tighten the mainspring. The outer peripheral end of the spring 4 is fixed to the case 5. An insertion hole 14 is bored in the side wall of the case 5 facing the upright piece 8, and an adjustment screw 15 is inserted through the insertion hole 14 and screwed into the screw hole 9 of the upright 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 TI4 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 arm 2 is attached to rotating shaft 1, and arm 2
A door body 3 is attached to the tip. 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 screen having the structure as shown in 42 is closed with the door body 3 facing vertically, and opened with the door body 3 facing upward and horizontally, as shown in Figure 42. Although not shown, there is a stopper for closing the book to prevent further rotation in the closing direction when the door body 3 is oriented vertically, and a stopper for preventing further rotation in the closing direction when the door body 3 is oriented horizontally. A stopper for opening is provided to prevent rotation in the opening direction. In the embodiment shown in FIGS. 1 and 3, columns 16 are erected on both sides of the premises that will be used as a storage area, and the case 5 is attached to the top of this column 16.
Although an embodiment is shown in which the case 5 is a part of the support 16, the case 5 may be attached to a building wall, fence, or other borrowed property without using the support 16.

The operation of the garage door constructed as described above for dogs will now be described.

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 is prevented from rotating any further. At this time, a force acts on the mainspring spring 4 in the opposite direction to the ground, ν
・However, the rotational moment applied to the rotating part 9 due to the weight of the door body 3, arm 2, etc. exceeds the rotational moment caused by the mainspring spring 4 that tries to rotate the door body 3 in the closing direction, so it hits the closing stopper and is closed. The state is maintained. 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, and stops at the set stop position when it hits the opening stopper. There is. At this time, the door body is 3'$.

Since the rotational moment that tries to rotate the door body 3 in the closing direction due to The body 3 is prevented from rotating in the closing direction. In addition, 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 main spring 4. When the door body 3 is closed, it hits the closing stopper and stops.

[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 located on the rotational trajectory of the arm, and the mainspring can be moved around the case etc. without being hindered by the rotation of the arm. It is now possible to cover it with

Further, 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.
