BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing main components of an automatic door. Guides 2 for preventing lateral shake are fitted to both ends of the upper surface of the door 1, and a joint 3 is attached to a substantially central portion thereof. The linear motor 4 has a lower portion of the mover 5 protruding from the lower surface, and this portion is fitted into the joint 3. Both ends in the longitudinal direction of the linear motor 4 are attached by a support bracket 11 and a fastening bracket 21 which are mounted between the grooves 7 of the kamoi 6.

As shown in FIGS. 2 to 4, the support bracket 11 is provided with a support surface 12 for mounting and supporting one end portion 4a of the linear motor 4 in the longitudinal direction. A facing wall 13 is formed so as to stand and face each other. The linear motor 4 is protruded inward from the facing wall 13.
A sandwiching piece 14 is formed so as to elastically contact the side surface of the. Also,
At the upper end of the facing wall 13, a restriction piece 15 protruding between the facing surfaces is provided.
And a linear motor 4 supported on the support surface 12
It is designed to regulate the upward movement of the. And
The position of the front edge 12a of the support surface 12 is set to the rear edge 1 of the regulating piece 15.
It is retracted from the position of 5a.

The outer width dimension of the facing wall 13 is formed to substantially match the groove width of the duck 6, and positioning pieces 16 and 17 in the width direction are formed at four positions on the left, right, front and rear of the lower end. The rear positioning piece 17 is the vertical frame 8 of the kamoi 6.
It is also the positioning in the longitudinal direction in which it is brought into contact with a for positioning. The support bracket 11 positioned by the positioning pieces 16 and 17 is attached to the upper surface of the duck 6 by driving the nail 19 into the nail hole of the attachment piece 18 formed on the outer side of the facing wall 13.

The fastening bracket 21 is shown in FIGS. 2, 5 and 6.
As shown in FIG. 7, the nut member 23 is attached to the end of the duck 6 so as to face the support bracket 11, and is fitted to the bolt insertion hole provided in the center in the width direction on the upper surface 22.
Is fixed. The support piece 24 is bent and horizontally protrudes between the grooves 7 of the kamoi 6 at a position lower than the upper surface 22. A retaining hole 25 is formed in the support piece 24. At the rear end portion of the fastening bracket 21, a pair of positioning pieces 26 whose outer width dimension substantially matches the width of the groove 7 of the duck 6 are formed by bending. The vertical bending portion 26a of the positioning piece 26 is positioned in the width direction, and the vertical bending portion 2a
The horizontal bent portion 26b bent from 6a has a rear end 6
The positioning is performed in the longitudinal direction so as to abut the vertical frame 8b. The fastening bracket 21 positioned by the positioning piece 26 is mounted on the upper surface of the duck 6 by driving the nails 19 into the nail holes of the mounting portions 27 formed at both ends.

A fastening piece 31 is fixed to the other end 4b of the linear motor 4. The fastening piece 31 includes a fixed plate 32 and a fastening plate 33 bent at a right angle to the fixed plate 32. The fixed plate 32 is brought into contact with one side surface of the linear motor 4 and fixed by a bolt 34. There is. A bolt insertion hole 35 is formed in the protruding end of the fastening plate 33 that goes around the lower surface of the linear motor 4. Further, the fastening plate 33 is formed with a hook claw 36 that is bent downward. Fastening plate 33
The horizontal distance between the bolt insertion hole 35 and the hook claw 36 is substantially equal to the horizontal distance between the nut member 23 of the fastening bracket 21 and the hook hole 25.

In order to mount the linear motor 4, as shown in FIG.
a is inserted between the opposing walls 13 of the support bracket 11. In this case, the front edge 12a of the support surface 12 of the support bracket 11
Is retracted from the position of the trailing edge 15a of the restriction piece 15, so that the one end portion 4a of the linear motor 4 can be inserted between the opposing walls 13 in a tilted posture, and is formed to project between the opposing walls 13. The sandwiching pieces 14 elastically contact each other to sandwich both side surfaces of the inserted one end portion 4a of the linear motor 4.

Then, the other end portion 4b of the linear motor 4 in the inclined posture is lifted to support the support surface 12 of the support bracket 11.
Fastening piece 3 placed on top and fixed to the other end 4b
The retaining claw 36 formed on the first fastening plate 33 is retained in the retaining hole 25 of the support piece 24 of the fastening bracket 21. As a result, the linear motor 4 can be temporarily placed in a substantially horizontal posture as shown in FIG. In this state, the bolt insertion hole 35 of the fastening plate 33
Since the position of the nut member 23 of the fastening bracket 21 matches, the fastening bolt 37 inserted into the bolt insertion hole 35 is screwed into the nut member 23 and fastened. An operator does not need to hold the linear motor 4 by hand when tightening the bolts.

In addition, instead of the engaging hole 25 of the support piece 24 of the fastening bracket 21, an upward engaging claw is formed,
Instead of the hook 36 of the fastening piece 31, a hook hole may be formed. Further, when the bolt tightening work is performed while holding the linear motor 4 by hand, it is not necessary to form the hook hole and hook.

In the structure for mounting the linear motor for the automatic door according to the present invention, the linear motor 4 is mounted from between the grooves 7 of the duck 6 and it is not necessary to remove the rail cover unlike the prior art. In addition, the linear motor 4 is attached to the support bracket 11.
One end 4a of the linear motor 4 is inserted in an inclined posture, the other end 4b of the linear motor 4 is lifted to a horizontal posture, and the fastening piece 31 fixed to the other end 4b is bolted to the fastening bracket 21. The installation work is easy. Further, by providing the hooking hole 25 and the hooking pawl 36 in the fastening bracket 21 and the fastening piece 31, the linear motor 4 can be temporarily placed in a substantially horizontal posture when tightening the bolts, and the worker Since it is not necessary to hold by hand, the safety of work can be secured.

The opposing wall 13 of the support bracket 11
Since the sandwiching piece 14 projects between and elastically contacts both sides of the inserted linear motor 4 to sandwich it, one end 4a of the linear motor 4 is positioned in the width direction. Further, the restricting piece 15 can restrict the upward movement of the linear motor 4 that is merely placed on the support surface 12. Further, since the support bracket 11 and the fastening bracket 21 are formed with the positioning pieces 16, 17 and 26a in the width direction and the positioning pieces 17 and 26b in the longitudinal direction, respectively, they are mounted between the grooves 7 of the kamoi 6. Thus, the work of fixing the linear motor 4 at a predetermined position can be performed quickly, and the accuracy of mounting the linear motor 4 can be improved.

As described above, the door 1 is fitted into the duck 6 to which the linear motor 4 is attached, and the linear motor 4 pulls the door 1 to automatically open and close it. As shown in FIG. 1, FIG. 4 and FIG. 7, the joint 3 attached to the substantially central portion of the upper surface of the door 1 has a linear motor 4 between the pulling arms 3a whose both ends are bent at right angles and face each other. The lower part of the mover 5 protruding from the lower surface is fitted. A rubber cushion 41 is attached to the facing surface of each towing arm 3a.

As described above, the door 1 and the linear motor 4 can be connected to each other by pulling only the lower part of the movable element 5 between the pulling arms 3a of the joint 3, so that the door 1 and the linear motor 4 can be connected to the duck 6 by a conventional method. Similar to the sliding door, the door 1 can be fitted and removed without removing the rail cover. Further, vibrations when the door 1 is opened and closed are absorbed by the rubber cushions 41 attached to the facing surfaces of the respective towing arms 3a and are not directly transmitted to the mover 5 of the linear motor 4, so that the linear motor 4 operates smoothly. .
