Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which is intended to explain in detail enough to be able to easily carry out the invention by those skilled in the art to which the present invention belongs, It does not mean that the technical spirit and scope of the present invention is limited.

As shown in Figure 2 to 6, the present invention is a door frame mounted in the automatic door installation section of the building, and a guide formed in the door frame and the guide protrusion for slidingly supporting the roller of the automatic door door in the automatic door opening and closing direction It is applied to the automatic door guide rail fixing device having the rail.

The automatic door guide rail fixing device according to the present invention is mounted between the bottom surface of the guide rail 10 and the inner bottom surface of the door frame 11 and the guide rail 10 with respect to the bottom surface and one side of the door frame 11. A lower movable piece (12) spaced apart from the body (12) formed on the upper surface and movable in the horizontal direction on the body (12) and having one end supported by the lower locking step (13) of the door frame (11); 14) and when the fastening member 15 coupled to the lower movable piece 14 is in close contact with the other end of the lower movable piece 14, the upper end of the locking jaw (16a) and the locking jaw (12a) of the body 12 It is provided with a lower holder (A) made of a fixing piece 16 for holding and supporting the lower end of the guide rail (10) seated therebetween.

At this time, the first stopper 25 for limiting the movement of the lower moving piece 14 is formed on one side of the inner surface of the body 12 of the lower holder (A), the fixing piece (the other side of the inner surface of the body 12) The second stopper 26 which limits the movement of the 16 is formed to face.

Automatic door guide rail fixing device according to the present invention, the inner and outer fixing members (18, 19) sliding and fixed to the inner and outer rail grooves 17 formed on the upper guide rail 10, and the long hole formed in the vertical direction ( A connecting member 21 fixed to the outer fixing member 19 by the fastening member 27 so as to be movable up and down by the outer fixing member 19 and the connecting member 21 to be movable in a direction perpendicular to the guide rail 10. The upper end of the upper movable piece 22 is fixed to the upper end 22, the upper end of the upper movable piece 22 in accordance with the fastening of the upper movable piece 22 on the connecting member 21 to the upper locking jaw 23 of the door frame 11 It is provided with the upper holder B which consists of a fastening member 24 for close contact.

In the drawings, reference numeral 28 denotes a guide protrusion in which a roller R mounted above the automatic door door D is seated so as to slide.

Hereinafter, the operation of the automatic door guide rail fixing device according to the present invention will be described in detail with reference to the accompanying drawings.

First, the process of fixing the lower part of the guide rail to the door frame using the lower holder will be described.

As shown in Fig. 4, 5 and 6, by mounting the lower holder (A) on the inner bottom surface of the door frame 11 to be installed in the automatic door installation section of the building, the guide rail 10 to the bottom of the door frame 11 Spaced from the side and one side. That is, the lower end of the guide rail 10 is seated between the locking jaw 12a of the body 12 and the locking jaw 16a of the fixing piece 16, and then the fastening member 15 coupled to the lower moving piece 14. When one side of the lower moving piece 14 is tightened, as shown by an imaginary line in FIG. 5, the lower moving piece 14 moves in the left direction to closely contact the lower locking jaw 13 of the door frame 11.

Accordingly, the lower portion of the guide rail 11 seated between the locking jaw 12a of the body 12 and the locking jaw 16a of the fixing piece 16 may be fixedly supported, and the locking jaw 12a of the body 12 may be fixed. By separating the guide rail 10 from the door frame 11 by) it can reduce the generation of noise due to their frictional contact when opening and closing the automatic door.

On the other hand, after fixing the inner and outer fixing members (18, 19) slidingly coupled to the rail groove (17) formed on the upper guide rail 10 by using the fastening member, the outer fixing member (19) by the fastening member (27) By controlling the fixing position of the connecting member 21 in the vertical direction by the long hole 20 formed in the connecting member 21 is fastened to the () to adjust the gap between the top of the door frame 11 and the guide rail (10).

Next, the process of fixing the upper end of the guide rail to the door frame using the upper holder will be described.

As shown in FIGS. 3 and 5, as the fastening member 24 coupled to the top of the connecting member 21 is fastened, the end of the upper movable piece 22 is shown as an imaginary line in FIG. 5. Moving in the upper left direction is in close contact with the upper locking jaw 23 of the door frame (11).

Therefore, the end of the upper movable piece 22 is in close contact with the upper locking jaw 23 of the door frame 11 can support the upper portion of the guide rail 10, the upper end of the guide rail 10 is the door frame 11 By spaced apart from the inner surface of the automatic door opening and closing can reduce the noise caused by their frictional contact.

As described above, the automatic door guide rail fixing device of the present invention has the following advantages.

When the automatic door is opened and closed, the guide rail for slidingly supporting the roller of the automatic door door can be installed in the door frame, thereby improving workability, thereby greatly reducing the installation and operation cost of the automatic door.

In addition, by reducing the mutual contact area of the guide rail for the door frame can minimize the noise generated when opening and closing the automatic door can improve the reliability.
