Abstract

PROBLEM TO BE SOLVED: To provide a door mounting structure for an automatic door which allows easy mounting operations. SOLUTION: A door 1 can be installed and removed without removing a transom cover in the same manner as with a conventional sliding door fitted into a groove 8 in a lintel 7, since the door 1 can be tractably connected to a linear motor 6 by simply fitting the lower part 11a of a movable element 11 between the upright parts 3a of a joint 3. Since the lower part 11a of the movable element 11 is fitted between the upright parts 3a to bind the entire movable element 11, vibration is unlikely to occur during opening and closing movements and the door 1 can be opened and closed silently and smoothly. Since vibrations generated during opening and closing of the door 1 are taken up by cushion rubber 12 attached to each upright part 3a and are thus not directly transmitted to the linear motor 6, the linear motor 6 operates smoothly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mounting structure for an automatic door.

[0002]

2. Description of the Related Art A conventional door mounting structure for automatic doors is
As shown in FIG. 5, the linear motor a and the guide rail b are horizontally fixed to the frame member c, and at least 2 are mounted on the upper surface of the door d.
A cushion in which one hanger e is fixed, the roller f attached to the hanger e is placed on the guide rail b, and one hanger e and the mover g of the linear motor a are attached to the lower part of the mover g. It was connected by the joint h via the material i.

[0003]

However, the door d
In order to mount, the working space for mounting the roller f on the guide rail b must be secured in the front-back direction orthogonal to the opening / closing direction. Further, since the one hanger e and the mover g are connected by the joint h, the mover g is partially constrained and is likely to vibrate when the door d is opened and closed. Further, it is necessary to cover the secured working space in the front-rear direction and to mount a column cover j for hiding the linear motor a, the guide rail b, etc., and also to remove the column cover j each time the door d is attached and detached. Workability is not good. The present invention has been made to solve the above problems, and an object of the present invention is to provide a door mounting structure for an automatic door that is easy to mount.

[0004]

In order to achieve the above-mentioned object, a door mounting structure for an automatic door according to a first aspect of the present invention is an automatic door which is opened and closed by a linear motor arranged in a groove of a duck. A structure for mounting a door for use, in which a joint is fixed to the upper end of the door at a distance such that both ends substantially match the length of the mover of the linear motor, and the mover is fitted between both rising parts of the joint. It is characterized in that the upper end of the door is fitted into the groove portion of the kamoi so as to be retracted, and the lower end of the door is movably fitted to a guide rail arranged parallel to the kamoi.

According to a second aspect of the present invention, in the attachment structure for an automatic door according to the first aspect of the present invention, in the structure according to the first aspect, a cushion rubber is fitted to the rising portion of the joint to raise the joint. It is characterized in that the portion and the mover of the linear motor are engaged with each other via the cushion rubber.

[0006]

According to the door mounting structure for an automatic door of the present invention as set forth in claim 1, the upper end of the door is fitted into the groove portion of the kamoi, and the groove portion of the kamoi is provided between the both rising portions of the joint. The mover of the arranged linear motor is fitted and the lower end of the door is movably fitted to the guide rail to be attached. Just by fitting the mover between both upright parts of the joint and fitting the lower end to the guide rail, the door can be connected to the linear motor so that it can be towed. The door can be installed and removed without removing the cover. In addition, the mover fits between both upright parts of the joint,
Vibration is less likely to occur because the entire mover is constrained. Therefore,
You can open and close the door lightly.

According to the automatic door door mounting structure of the present invention as defined in claim 2, vibrations at the time of opening and closing the door are directly absorbed by the cushion rubber fitted to both upright portions of the joint. The linear motor operates smoothly because it is not transmitted to the mover of the motor.

[0008]

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 end of the door 1, and a joint 3 is attached to a substantially central portion in the longitudinal direction. In addition, a pair of door rollers 5 that fit into the guide rails 4 and travel are disposed at the lower end of the door 1. Both ends in the longitudinal direction of the linear motor 6 are attached by a door-end side bracket 9 and a door-end side bracket 10 which are laid across the groove portion 8 of the kamoi 7, and a lower portion 11a of the mover 11 projecting from the lower surface of the outer rail of the linear motor 6 is attached.
Are arranged in the groove 8 of the kamoi 7.

A joint 3 attached to a substantially central portion of the upper end of the door 1 has an upright portion 3 in which both ends are bent at right angles to stand up.
a is formed. The distance between the facing surfaces of the upright portions 3a substantially matches the dimension of the lower portion 11a of the mover 11 in the longitudinal direction. The cushion rubber 12 is fitted to the facing surface of each standing portion 3a.

In order to mount the door 1 in the automatic door having the above construction, the upper end of the door 1 is fitted into the groove 8 of the kamoi 7 from an obliquely lower position, and the mover 11 of the linear motor 6 arranged in the groove 8 of the kamoi 7 is mounted. The lower part 11a of the joint 3 is fitted between the upright portions 3a of the joint 3 attached to the upper end of the door 1. Then, the door roller 5 arranged at the lower end of the door 1 is movably fitted to the guide rail 4.

As described above, the door 1 can be connected so that it can be pulled only by fitting the lower portion 11a of the mover 11 between the upright portions 3a of the joint 3, so that the door 1 can be fitted in the groove portion 8 of the kamoi 7 like the conventional sliding door. Without removing the rail cover
The door 1 can be attached and detached. Further, since the lower portion 11a of the mover 11 is fitted between the upright portions 3a and the whole mover 11 is restrained, vibration is unlikely to occur during the opening and closing operation, and the door 1 can be opened and closed lightly. Further, vibrations when the door 1 is opened and closed are absorbed by the cushion rubbers 12 fitted to the upright portions 3a and are not directly transmitted to the mover 11 of the linear motor 6, so that the linear motor 6 operates smoothly.
