Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a door stopper device.

[Prior art and its problems]

Doors such as automatic doors are hung from a hanger rail provided inside the door so that they can be opened and closed via a hanger with a door roller, and a door is placed at the end of the hanger rail in the opening direction to stop the movement of the door. Requires a stopper.

As a conventional stopper, Utility Model 61-137767
As in the publication, the mounting bracket is inserted into the groove having the protruding part of the hanger rail, and the stopper bracket with the rubber pad is attached to the mounting bracket with a screw.
A common structure is that the protrusion is sandwiched between two metal fittings.

However, in the case of such a stopper,
The number of parts is large, and it is necessary to temporarily fasten the mounting bracket and attach the stopper bracket to the mounting bracket, making the installation troublesome. Furthermore, the structure makes position adjustment difficult.

This invention was proposed to solve the above-mentioned problems, and its purpose is to provide a door stopper device that is easy to install and adjust its position, and can be firmly fixed.

[Means for solving problems]

The door stopper device according to this invention includes a stopper body 6, a stopper board 6A inserted into the lip groove 7 of the hanger rail 5, and a stopper board 6A that is integrally connected to the stopper board 6A and extends outside the lip groove 7. It is composed of a stopper board 6A and a stopper outer plate 6B that can be positioned parallel to the stopper board 6A, and the stopper outer board 6B is provided with a protruding part 6b that projects in the widthwise direction, and the stopper board 6A is fixed to the stopper board 6A by a retaining screw 8. 6A against the lip 11 of the lip groove 7, and press the stopper outer plate 6B.
The deformation of the stopper outer plate 6B toward the lip groove 7 side is prevented by the rebound set screw 10 attached to the stopper outer plate 6B.

[Effect]

Installation of the stopper body 6 is completed by simply inserting the stopper board 6A into the lip groove 7 and tightening the retaining screw 8. Spring set screw 10
This prevents the stopper outer plate 6B from deforming toward the lip groove 7 side when the hanger is stopped.

〔Example〕

This invention will be explained below based on an illustrated embodiment.

At the top of the door 1, there is a hanger 3 having a door wheel 2.
A stopper device is attached to the opening direction end of the hanger rail 5 attached to the lower part of the blind 4 so as to prevent the hanger 3 from moving.

This stopper device includes a stopper board 6A that inserts a stopper body 6 into a lip groove 7 of a hanger rail 5, and a stopper board 6A that is integrally formed with the stopper board 6A via a connecting portion 6c.
It consists of a stopper outer plate 6B that can be positioned outside, two retainer screws 8 are attached to the stopper base plate 6A, and a stopper rubber 9 and a rebound set screw 10 are attached to the stopper outer plate 6B.

On the surface of the stopper board 6A on the lip 11 side,
Knurls 12 are provided to increase contact resistance.

The stopper outer plate 6B is connected parallel to the stopper board 6A, and has an L-shaped protrusion 6b that protrudes in the widthwise direction at the tip, so that the hanger 3 is in contact with the protrusion 6b. is being used.

The stopper rubber 9 is a rubber tube that is covered with the protrusion 6b, and is made of, for example, a rubber hose cut into rings.

When the hanger 3 hits the protruding portion 6b, the stopper outer plate 6B may curl on the lip groove 7 side. To prevent this, a spring stopper screw 10 is provided, and the tip of the stopper outer plate 6B is attached to the lip groove 7. Press it lightly onto the bottom of the 7. Two screw holes 13 are provided for the spring stopper screw 10, and by selectively using the screw holes 13, interference with the mounting screw 14 of the rail is avoided.

In the above configuration, the stopper board 6
Installation of the stopper body 6 is completed by simply inserting the stopper A into the lip groove 7 and tightening the retaining screw 8. The stopper board 6A is pressed against the lip 11 by the reaction force of tightening and is fixed. Here, the tip of the retaining screw 8 is inserted into the lip groove 7, and the knurled eye 12 is inserted into the lip, so that a firm fixation is achieved and the stopper device is prevented from slipping.

Further, by loosening the screws 8 and 10, the stopper board 6A becomes loosely fitted, and can be easily moved within the lip groove 7, allowing for easy position adjustment.

Although the above description has been given of an example in which the hanger rail is attached separately to the blind, it goes without saying that the present invention can also be applied to a hanger rail that is integrated with the blind.

[Effect of idea]

As mentioned above, according to this invention, the stopper main body is connected to a stopper board inserted into a groove with a lip, and a stopper outside which is integrally connected to the stopper board and can be positioned outside the groove with a lip in parallel with the stopper board. The stopper board is pressed against the lip of the lip groove by a retaining screw attached to the stopper board, and the stopper outer plate, which has a protrusion for the stopper rubber, is prevented from deforming toward the lip groove side by a set screw. The stopper body can be installed by simply inserting the stopper board into the groove with the lip and tightening the retaining screw, making it easy to install and adjust the position. Deformation of the outer plate is prevented, and together with the pressing of the stopper board by the retaining screw, a strong fixation is achieved and a strong stopping force is obtained.
