There is a direct attachment type that is attached directly to the lintel 3.

However, conventionally, in the built-in type shown in Fig. 6, the two
The channel material 1 is fixed to the inner support plate 4, and a suspension wheel 9 fixed to an L-shaped hanging frame 8 is mounted on the upper surface of the rail 5 that is integrated with the channel material 1. The opening/closing door 6 is suspended by extending the horizontal portion 8a to the side opposite to the hanging wheel 9 and fixing the upper stile 7 of the opening/closing door 6 to this horizontal portion 8a with bolts 29, and is also provided on the hanging frame 8. A stopper roller 10 is attached to the lower surface of the rail 5, and a stopper door 11 is fixed to the lower surface of the blind 2.

In the direct mounting type shown in FIG. 7, the channel material 1 is attached directly to the side of the lintel 3, and a suspension wheel 9 fixed to an L-shaped suspension frame 8 is mounted on the upper surface of the rail 5 that is integrated with the channel material 1. , the horizontal portion 8a of this hanging frame 8
extends in the same direction as the hanging wheel 9, and this horizontal portion 8a
The opening/closing door 6 is suspended by fixing the upper stile 7 of the opening/closing door 6 with bolts 29, and the stopper roller 10 is attached in contact with the lower surface of the rail 5 as described above. A fitting door 11 was attached to the bottom surface.

``Problems that the invention attempts to solve'' As shown in Figure 6, in the built-in type, the fitted door 1
1 is attached to the lower surface of the blind 2, and the hanging frame 8
The opening/closing door 6 is attached facing toward the side opposite to the horizontal portion 8a. In such a built-in type, when installing the liner 13 for adjusting the height and inclination of the opening/closing door 6, there is a large space above the bolt 29, so the length of the vertical portion 8b of the hanging frame 8 may be short. However, in the direct mounting type shown in Figure 7,
When installing the liner 13, a space 14 of at least the same length as the bolt 29 must be formed below the bottom plate portion 12 of the channel material 1 above the bolt 29. Therefore, channel material 1
It is also effective to reduce the distance d between the bottom plate portion 12 and the rail 5, but this alone is not sufficient, and it is necessary to make the length of the vertical portion 8b of the hanging frame 8 longer than that of the built-in type. Therefore, this hanging frame 8 requires separate parts with different dimensions for the built-in type and the direct-mounted type, which not only causes trouble during installation work, but also requires many types of parts in stock. Ta.

``Means for solving problems'' This invention is based on a rail formed from channel material.
In an automatic door that slides to open and close the door while moving with a hanging wheel installed on a hanging frame at the upper end of the door, a stopper rail is installed on the channel material above the rail and at a position shifted from the rail. The suspension frame is made up of a door support plate attached to the upper end of the door, and a suspension wheel support plate to which the suspension wheel is attached, and the suspension wheel support plate is composed of a vertical plate, and the rear surface part thereof has an axis on the vertical center line.

"Effects of the Invention" Since the present invention is configured as described above, it has the following effects.

(1) Can be used not only as a built-in type but also as a direct-mounted type. In particular, when used as a direct-mount type, there is no need to provide extra space between the bolt for connecting the door support plate and the upper stile and the bottom plate of the channel material.

(2) Since it can be used in both the built-in type and the direct-mounted type, there is no installation error, and the type and quantity of inventory items can be reduced.

(3) Since the locking roller is removably attached to the suspension wheel support plate, even if the fitting gap for the locking roller is small, the locking roller can be attached to the hanging wheel support plate after the opening/closing door is placed on the rail.

(4) The contact position of the hanging wheel with the rail and the contact position of the stopper roller with the stopper rail are staggered, so the load of the opening/closing door is transferred between the hanging wheel and the stopper roller, which are constantly in contact with each other without any gaps. This allows you to reliably eliminate the need to stop the doors from opening and closing.

(5) Installation adjustments can be made without removing the door from the rail. That is, by slightly loosening the fixing bolt and turning the adjusting bolt in the tightening or loosening direction while checking the gap, the inclination of the door can be adjusted. After adjustment, all you have to do is tighten the fixing bolts, making it extremely easy to operate.

(6) When adjusting the height and inclination of the opening/closing door 6, there is no need to bring many types of liners to the site or keep them in stock, as was the case in the past.

(7) Even if the building becomes deformed after a long period of time, it can be adjusted without any parts.

(8) Since the adjustment bolt is located on the vertical center line of the suspension wheel support plate and the door support plate, each part, especially the suspension wheel support plate, can be kept in a horizontal state without twisting or tilting during adjustment. The height is adjusted while it is held at the same position.

(9) The adjustment bolt is used in such a way that it is subjected to a tensile load that exhibits great strength, so there is less chance of the adjustment bolt breaking.

(10) The lower surface of the head of the adjustment bolt is in surface contact with the protruding part of the suspension wheel support plate, so the contact area is relatively wide, the load applied per unit area is distributed, and the hole is Since it goes through, it is stable when turning the adjustment bolt.

(11) Since the adjustment bolt is located on the front side of the hanging frame, it is easy to turn and adjustment work can be done smoothly and accurately.
