JPH06543Y2 - Door stop device for automatic doors - Google Patents

Description

TECHNICAL FIELD The present invention relates to a door stop device for stopping a door of an automatic door at a predetermined position.

2. Description of the Related Art As shown in Japanese Utility Model Laid-Open No. 59-96268, a stopper is fixed to a guide rail of a door roller attached to the upper edge of the door with a screw or the like, and the door roller is brought into contact with the stopper to bring the door to a predetermined position. The door stop position to stop is known.

Problems to be Solved by the Invention In such a door stopping device, since the door roller contacts the stopper, the door roller moves over the stopper and the stop positioning accuracy deteriorates.

On the other hand, a detector that detects that the door stops at a predetermined position is attached to the door frame seamlessly, but the stopper is positioned and attached at a position corresponding to the opening width and door width of the door,
Since the detector is mounted according to the mounting position of the stopper, the work is troublesome, and if an error occurs in the mounting position of the detector, it cannot be accurately detected that the door has stopped at a predetermined position.

Means and Actions for Solving the Problems A stopper is attached to the guide rail, a receiver facing the stopper is provided on the hanger equipped with a door roller, and a door detector is attached to the stopper to attach the receiver and the stopper. The door can be stopped accurately at a predetermined position by abutting,
The positional relationship between the stopper and the detector can always be kept constant.

Example A hanger 2 fixed to the upper edge of the door 1 is provided with a horizontal plate 3 and a vertical plate 4, and the horizontal plate 3 is fixed to the upper edge of the door 1 with bolts 5 and a door roller 6 is attached to the vertical plate 4. Is supported by this door car 6
Is mounted on the guide rail 8 of the blind 7, and the stopper 9 is attached to the guide rail 8.

The stopper 9 includes a downward U-shaped stopper piece 10 and a lateral U-shaped mounting piece 11, and a lower horizontal plate 11a of the mounting piece 11 is provided.
Is fixed to the lower surface 8a of the guide rail 8 with a bolt 12, and the vertical plate 1 of the stopper piece 10 is fixed with a bolt 13 screwed to the upper horizontal plate 11b.
0a is pressed against the arc-shaped upper surface 8b of the guide rail 8, and the bracket 14 is fixed to the vertical plate 11c of the mounting piece 11 with bolts 15. The detector 16 is mounted on the bracket 14. Vertical plate 4 of the hanger 2
A stopper 17 made of a cushioning material is provided at one end of the stopper piece 1.
It is attached facing the vertical plate 10a of No. 0.

The L-shaped bracket 1 is attached to the other end of the vertical plate 4 of the previous hanger 2.
8 is fixed with a bolt 19, and a belt 20 is attached to the lateral piece 18a.
Is fastened by a presser 21, the belt 20 is wound around a drive pulley 22, and a mounting plate 23 is secured to the vertical piece 18b of the L-shaped bracket 18, and the mounting plate 23 has the above-mentioned seamless 7 A magnet 25 is attached to face the magnet switch 24 attached to.

The magnet switch 24 is mounted on a mounting piece 29 which is fixed to the recessed groove 26 of the blind 7 with a back plate 27 and bolts 28.

Then, when the drive pulley 22 is driven to rotate the belt 20, the door 1 opens and closes along the guide rail 8 via the door roller 6, and when the predetermined position is reached, the receiving body 17 vertically moves the stopper piece 10 of the stopper 9. The detector 16 detects the door 1 and senses that the door 1 has stopped at a predetermined position while coming into contact with the plate 10a and stopping.

At this time, since the receiving body 17 is made of a cushioning material, the door 1 stops without shock.

Further, when the position of the stopper 9 is adjusted, the detector 16 also moves together with it, which simplifies the operation and prevents the stopper 9 and the detector 16 from always having the same positional relationship and performing a detection operation by mistake. .

Advantageous effect of the invention The stopper 17 is brought into contact with the receiving body 17 made of a buffer body so that the door 1
Since the door is stopped, the door 1 can be stopped accurately at a predetermined position without shock.

Since the detector 16 is provided on the stopper 9, only the stopper 9 needs to be mounted at a position corresponding to the opening width and the door width of the door, which simplifies the work and the stopper 9
The positional relationship between the detector 16 and the detector 16 is always constant, and the fact that the door 1 has stopped at a predetermined position can be accurately detected without error.
