Description

[Detailed Description of the Invention] The present invention relates to a rail mechanism for supporting and guiding an automatic door such as a 5-pull, 9-pull, curved door.

Conventionally, in automatic doors, a door roller attached directly to a layer has been suspended from a rail, as shown in Japanese Utility Model Publication No. 54-39324.

That is, as shown in FIG. 1, a rail 1 integrally formed with the main body is placed above the entrance, a door banger 3 is fixed to the upper part of the door 2, and a door wheel 4 is rotatably attached to the door hanger 3. Install.

The door 2 is suspended directly on the rail 1 via the door roller 4, and the door 2 is opened and closed while the door roller 4 is supported and guided on the rail 1 by a drive source (not shown). .

However, this conventional device has the disadvantage that when the door roller runs on the rail when opening and closing the door, the running sound and vibrations are transmitted through the rail, causing the main body to vibrate and resonate within the drive device case, producing noise. there were.

Therefore, this invention was made in view of the above-mentioned drawbacks, and aims to reduce the noise of automatic doors by preventing the running noise and vibrations caused by the door roller running on the rails, thereby preventing the generation of noise. The purpose and gist of the material is to insert and attach one recess of the cushioning material, which has an approximately H-shaped cross section with recesses on the top and bottom, into the rail base, and attach the rail traveling body to the other four parts. Above is an automatic door rail mechanism configured to suspend a door roller installed on the door.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

2 and 3, the rail base 13 is attached to the main body 11 attached to the building or the sash body above the door 10, along the door opening/closing direction, that is, along the entrance/exit.
2, and a cushioning material 14 is placed on this rail base 13.
Install.

As shown in FIG. 3, this cushioning material 14 has a substantially H-shaped cross section and is made of an elastic material such as rubber or resin.

The cushioning material 14 has recesses 15 and 16 on the upper and lower sides, and the cross-sectional shape of the upper recess 15 is formed into a shape that matches the shape of the rail traveling body 17, that is, a substantially semicircular shape, and the rail traveling body 17 is bonded. It is fixed in the recess 15 with a compound or the like.

On the other hand, the width of the bottom part 16a of the lower recessed part 16 is the same as the width of the rail base 13, and the entrance part 16
The width of b is formed to be smaller than the width of the bottom portion 16a to form a trapezoidal shape.

Then, the rail base 13 is inserted into the lower recess 16 of the buffer material 14 to which the rail traveling body 17 is attached.

Then, since the entrance part 16b of the fourth part 16 is smaller than the width of the rail base 13, the rail base 13 is inserted while expanding in the left and right directions in the figure, and the cushioning material 14 expands downward in the figure as shown in FIG. state, and is clamped by the entrance portion 16b of this recess 16.

At this time, the cushioning material 14 is attached to the rail base 13 with the door 1
Since the cushioning material 14 is held along the opening/closing direction of the rail base 13, there is little chance of it falling off.
recess 16 and rail base 1 to ensure firm installation.
3 may be attached using adhesive or the like.

On the other hand, a door hanger 18 is attached to the top of the door 10,
A door wheel 19 is rotatably provided on this door hanger 18.

Then, the door 10 is suspended on the rail traveling body 17 via a door hanger 18 and a door roller 19.

Reference numeral 25 denotes an anti-slip roller that prevents the door 10 from swinging during opening/closing operations.
It is installed on 8.

In the device of the present invention having such a configuration, the door 10 is driven by a drive source (not shown) and is supported and guided by the rail running body 17 provided along the doorway with the door roller 19 to open and close the doorway. do.

During this opening/closing operation, when the door roller 19 runs on the rail running body 17, the running noise and vibrations are absorbed by the cushioning material 14 provided between the rail running body 17 and the rail base 13, thereby preventing the generation of noise and vibration. It is possible to reduce the noise of automatic doors.

In the embodiments shown in FIGS. 2 and 3, a rail running body 17 having a circular cross section is used, but a rail running body 20 having a square cross section as shown in FIG.
In this case, the recess 22 above the cushioning material 21 may be used.
It is also formed into a rectangular shape to match the rail traveling body 20.

Furthermore, in the above-mentioned embodiment, when attaching the cushioning material 14 to the rail base 13, the shape of the recess 16 at the bottom of the cushioning material 14 was made into a trapezoidal shape, but as shown in FIG. 4a, the shape of the rail base 13 is The cushioning material 21 and the rail base 13 are attached with adhesive.

Furthermore, in the above embodiment, the rail running body 17 was attached to the recess 15 of the buffer material 14 with adhesive, but as shown in FIG. The rail traveling body 17 can be inserted into the recess 24 up to a position a small distance α from the center of the recess 24, which is slightly deep.

Then, since the width m of the entrance portion 24a of the recess 24 is smaller than the diameter n of the rail traveling body 17, when the rail traveling body 17 is inserted into the recess 24, the rail traveling body 17 is inserted into the artificial part 24a of the recess. to hold.

Therefore, the rail traveling body 17 and the cushioning material 23 can be attached without using an adhesive, and can be attached even more firmly using an adhesive.

Furthermore, the methods for attaching the rail traveling body, cushioning material, and rail base shown in FIGS. 3 and 4 a and 1) may be freely combined, and the method is not limited to these methods.

As is clear from the above, according to the present invention, a shock absorbing material such as rubber having four upper and lower parts and approximately H-shaped in cross section is attached to the rail running body in the upper recess, and the lower recess is attached to the main body. Since it is inserted on the rail base, the shock absorbing material absorbs the running noise and vibration between the door roller and the rail running body that occur when opening and closing the door suspended on the rail running body via the door roller. This has the effect of preventing the generation of these running noises and vibrations, thereby making the automatic door less noisy.
