Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a ground leg to the ground of a garage door provided at the entrance of a garage.

[Background Art] In the case of a conventional garage door, a ground leg 12 is attached as shown in FIGS. 6 and 7. A back plate 16' is installed inside the groove 7 provided in the vertical frame 5 of the door body 1, and the locking pieces 8 on both sides of the opening of the groove 7 and the legs arranged on the outer surface side of the groove 7 of the vertical frame 5. The upper part of the grounding leg 12 is sandwiched between the clamping bracket 17' and the leg clamping bracket 17'.
A male threaded tool 14 inserted through the hole was screwed onto the back plate 16'. However, in such a conventional example, when the male screw 14 is loosened, the back plate 16' and the leg clamping fittings 17' fall down, so when performing vertical adjustment or installation, the back plate 16', the leg clamping fittings 17' and the grounding This had the disadvantage that it had to be done while supporting the legs 12, making it difficult to adjust and attach it up and down.

[Purpose of the invention] The present invention has been made in view of the above points, and the purpose of the present invention is to prevent the leg mounting seat and the leg clamp from falling even when the male screw is loosened, so that it is easy to ground. To provide a grounding leg mounting structure for a garage door that allows easy vertical adjustment and installation of the legs.

[Disclosure of the invention] The ground leg mounting structure of the garage door of the present invention connects one end of each arm 2 to both sides of the door body 1, and connects the other end of each arm 2 to a support 3 in a rotatable manner.
In a garage door that is closed when the door body 1 is rotated to face vertically and opened when the door body 1 is rotated upward to face horizontally, the hollow vertical A leg attachment seat 16 is installed in a groove 7 formed on the outer surface of the frame 5, and a male screw 14 is inserted from the through hole 16a of the leg attachment seat 16 into the through hole 18 at the bottom of the groove 7, and the vertical frame 5 is inserted. Screw the tip of the male screw 14 into the leg clamping fitting 17 placed inside, insert the upper part of the grounding leg 12 whose lower end is in contact with the ground G into the vertical frame 5, and insert the upper part of the grounding leg 12 into the groove 7. It is held between the bottom part and the leg holding fitting 17 and the male threaded fitting 14 is tightened, and the drawbacks of the conventional example are solved by constructing it as described above. That is, as described above, the male threaded tool 14 is inserted into the through hole 18 at the bottom of the groove 7, and together with the male threaded tool 14, the leg mounting seat 16 and the leg clamping metal fitting 17 are inserted.
The upper part of the grounding leg 12 is clamped between the bottom of the groove 7 and the leg clamping fitting 17 while the grounding leg 12 is temporarily fixed to prevent it from falling down. It can be adjusted up and down and installed easily.

The present invention will be explained in detail below with reference to examples.

As shown in FIG. 1a, the door body 1 is formed into a lattice-like structure by attaching a large number of vertical lattices 6 to a frame body consisting of upper and lower horizontal frames 4 and left and right vertical frames 5. A groove 7 is formed in the vertical direction on the side of the vertical frame 5 of the door body 1 on which the arm 2 is attached, and on both sides of the opening of the groove 7 there are locking pieces 8 that protrude toward the inner package. are formed in the vertical direction. This vertical frame 5 is hollow inside. As shown in FIG. 2, an upper mounting plate 9 and a lower mounting plate 10 are installed inside the groove 7 so as to be movable up and down. This prevents it from coming off to the opening side. The upper mounting plate 9 and the lower mounting plate 10 are provided with male screw holes. An upper fitting 11 is disposed on the upper part of the vertical frame 5, and the upper fitting 11 is attached to the upper mounting plate 9 with bolts 13, and an insertion portion 11a is made to protrude from the upper fitting 11. In this embodiment, the groove 7
A recess 7a is further provided at the bottom of the recess 7a, into which the tip of the bolt 13 is accommodated. Arm 2
is composed of a square pipe-shaped upper arm 2a and a square pipe-shaped lower arm 2b. Upper arm 2a
One end is the upper mounting bracket 1 on both sides of the door body 1
1 and fasten bolts to connect the upper arm 2a and the door body 1 so that they are perpendicular to each other, and one end of the lower arm 2b attaches one end of the lower arm 2 to the mounting plate 10. are connected to the central portions of both sides of the door body 1. The other end of the upper arm 2a and the other end of the lower arm 2b are connected by a connector, and the other end of the upper arm 2a and the other end of the lower arm 2b are rotatably connected to the upper part of the column 3 by a rotation shaft. ing. As shown in FIG. 3, the grounding leg 12 includes a U-shaped rod 12a and a wheel portion 12 rotatably attached to the lower part of the U-shaped rod 12a.
b. At the bottom of the groove 7, a through hole 18 is bored in the recess 7a at the bottom of the groove 7, as shown in FIG. Ingredients 14
is inserted into the through hole 18. At this time, a washer 19 is interposed between the leg attachment seat 16 and the head of the male screw 14. Figures 3 and 4 are inside the vertical frame 5.
As shown in the figure, a leg clamp 17 is arranged, and the tip of the male threaded fixture 14 is screwed into a screw hole of the leg clamp 17. Curved portions 17a are provided on both sides of this leg clamping fitting 17. U-shaped rod 12a of ground leg 12
The upper part is inserted into the vertical frame 5 and between the bottom of the groove 7 and the leg clamping fitting 17, and is fixed by tightening the male screw fitting 14. U of ground leg 12
When inserting the upper part of the mold bar 12a, the recess 7a serves as a guide and the upper part of the mold bar 12a can be inserted smoothly into the vertical frame 5. After installing the grounding leg 12. Male thread tool 14
The height of the grounding leg 12 can be freely adjusted by loosening and moving the grounding leg 12 up and down.

The garage door configured as described above operates as follows. The closed state is when the door body 1 faces vertically as shown by the solid line in FIG. 1b, and the arm 2 hits a lower limit stopper (not shown) to prevent further rotation. At this time, the grounding leg 12
The lower end wheel portion 12b is grounded on the ground G and is supported so that no force is applied to the arm 2 or the rotation support portion. When one of the door bodies 1 is held and pushed upward, the door body 1 swings upward, and the arm 2 stops when it hits the upper limit stopper (not shown), as shown by the imaginary line in Fig. 1b. The door body 1 is in an open state with the door body 1 facing upward and laterally. Further, when the door body 1 is pushed down, the door body 1 rotates downward, and the door body 1 is closed vertically as shown by the solid line in FIG.
The wheel portion 12b is grounded on the ground G.

[Effect of the invention] As described above, the present invention incorporates a leg mounting seat in a groove recessed on the outer surface of a vertical frame with a hollow interior of the door body. Insert the male screw into the rotating frame, screw the tip of the male screw into the leg clamping fitting placed inside the vertical frame, insert the upper part of the grounding leg whose lower end is in contact with the ground into the vertical frame, and insert the upper part of the grounding leg into the vertical frame. is sandwiched between the bottom of the concave groove and the leg clamping bracket, and the male screw is tightened, so even if the male screw is loosened, the leg mounting seat and the leg clamping bracket are temporarily secured to prevent them from falling downward. When installing the grounding leg and adjusting the vertical position of the grounding leg, it is only necessary to support the grounding leg, making it easy to attach and adjust the grounding leg up and down.
