Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a stopper device for stopping an automatic door at a predetermined position.

Prior Art As shown in Japanese Utility Model Application Publication No. 59-96268, a pair of upward protrusions is provided on a U-shaped solid rail portion, and a stopper is clamped between the pair of upward protrusions. A stopper device is known in which a door roller attached to a door is brought into contact with a stopper to stop the door at a predetermined position.

Problems that the invention aims to solve: Since the stopper is clamped between a pair of upward protrusions, the bolt for that purpose must be screwed laterally from the direction of the open opening, and the bolt must be tightened,
The cover that covers the open opening gets in the way when loosening the door, so when changing the position of the stopper to adjust the door stop position, the cover must be removed and reattached. Work becomes troublesome.

Means and Effect for Solving Problems A rail portion having a guide rail 5 is provided at the bottom of the U-shaped horizontal frame, a stopper body 12 is placed on the upper surface of this rail portion, and a mounting body 13 is placed on the lower surface of the rail portion. At the same time, the portion of the stopper body 12 that protrudes from the rail portion and the portion of the mounting body 13 that protrudes from the rail portion are vertically butted against each other, and the stopper body 12 and the mounting body 13 are connected by vertical screws 19. , and screw 19 can be tightened and loosened from below.

Embodiment FIG. 3 is a cross-sectional view of the upper part of an automatic door, in which a U-shaped engine case 2 is installed inside the U-shaped opening 1, and a substantially V-shaped lower side wall 3 of the engine case 2 is provided. A guide rail 5 is formed with a concave groove 4 and a generally upward U-shaped concave groove, and a door roller 8 attached to a door 6 via a hanging fitting 7 can run freely on the guide rail 5. The lower horizontal wall 3 serves as a rail section.

Reference numeral 9 denotes a cover body, which is attached to the open end of the upper horizontal wall 10 of the cover 1 and covers the opening of the cover 1 and the engine case 2.

FIG. 4 is a schematic front view with the cover removed, and the engine case 2 includes a drive pulley 3.
0 and a driven pulley 31 are disposed, and a belt 32 is wound between both pulleys.
2 is connected to the hanging fitting 7, and the door 6 is opened and closed by a belt 32 by driving a drive pulley 30 with a motor 33.

A stopper device 11 is attached to the lower horizontal wall 3 so as to cross the guide rail 5.

The stopper device 11, as shown in FIG.
A stopper body 12 and a mounting body 13 are provided, and the stopper body 12 has a downward U-shape with a horizontal piece 14 and vertical pieces 15 and 16 on both sides. Receiving piece 18 made of elastic material
is attached, the horizontal piece 14 is placed on the protrusions 3a, 3a on both sides of the guide rail 5 of the lower horizontal wall 3, that is, on the upper surface, the vertical piece 15 on one side is in contact with the groove 4, and the vertical piece 15 on the other side is in contact with the groove 4. The stopper body 12 crosses the guide rail 5 so that the vertical piece 16 projects toward the cover body 9 side.

The mounting body 13 has a thin plate shape, contacts the lower end surface 16a of the other side vertical piece 16 and the lower surface 3b of the lower horizontal wall 3, and is tightened to the horizontal piece 14 with screws 19, so that the horizontal piece 1
4 against the protrusions 3a, 3a, and press the stopper body 1.
2 is fixed to the lower horizontal wall 3.

As shown in FIG. 5, the mounting body 13 has a hook shape with one side piece 13a and the other side piece 13b, and the one side piece 13a is in contact with the lower surface 3b of the lower horizontal wall 3.
The end surface of the other side piece 13b may be brought into contact with the horizontal piece 14 and tightened with the screw 19.

Because of this, the screw 19 can be screwed in vertically from below, and the screw 19 can be tightened or loosened without removing the cover body 9, so the position of the stopper body 12 can be adjusted. Easy to adjust.

In the above embodiment, the engine case 2 is provided in the blind 1, but a guide rail may be formed in the blind 1 and the engine case may be omitted.

That is, a rail portion having a guide rail may be provided at the lower part of the U-shaped horizontal frame, and the door roller may be provided on the guide rail so as to be freely movable, and the opening of the horizontal frame may be covered with a cover body.

Effect of the invention Since the screw 19 can be tightened and loosened from below, the stopper body 12 can be tightened and loosened without removing the cover body 9.
The stopping position of the door 6 can be adjusted by easily changing the position of the door.
