BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting an upper rail provided inside a channel material which is mounted on a blind or a door as an automatic door mounting frame.

[0002]

2. Description of the Related Art As shown in FIG. 4, there are two types of automatic doors: a built-in type in which a channel material 1 is built in a blind 2; . Inside the channel material 1, a mounting portion 12 for mounting a controller, a drive motor, a pulley, and the like, a lead wire storage groove 13 for storing a lead wire 14, and a hanging wheel 9 of the door 6 roll. The upper rail 5 and the like are made by extruding aluminum.

In the case of the built-in type shown in FIG. 4, the upper rail 5 has a distance d1 from the back of the channel material 1.
In the case of the direct mounting type shown in FIG. 5, the distance d2 from the back of the channel material 1 is short. Therefore, two types of the channel material 1 for the built-in type and the channel material 1 for the direct mounting type are required.

[0004]

However, the upper rail 5 has to be replaced when it is worn out for a long period of time. However, the channel material 1 is for the built-in type and for the direct mounting type. Therefore, there is a problem that two kinds of channel materials 1 must always be prepared for replacement.

In the present invention, the upper rail 5 is worn out.
In such a case, it is an object of the present invention to provide a channel member 1 that can be easily replaced between a built-in type and a direct-attached type and that can be securely attached.

[0006]

According to the present invention, a channel 9 serving as an automatic door mounting frame is provided with a hanging wheel 9 for the opening and closing door 6.
The channel material 1 and the upper rail 5 are formed separately from each other, and the upper rail 5 has a horizontal portion having a different length between a built-in type and a direct mounting type. 30 and a vertical portion 31 having the same length between the built-in type and the direct mounting type, and the inside of the channel material 1 is provided with an engaging portion 20 at the upper end of the vertical portion 31 and the horizontal portion 3.
The engaging member 23 for engaging the upper rail 5 is provided at predetermined intervals at upper and lower sides to engage the upper rail 5, and is located between the engaging part 20 and the engaging part 23 inside the channel material 1. A nut fitting groove 24 is formed, and the nut fitting groove 24 is formed with an intermediate gap between an inverted L-shaped bent from above and an L-shaped bent from below. A plurality of rectangular nuts 25 are slidably fitted in the fitting grooves 24, and a nut supporting screw hole 26 and a rail holding screw hole 27 are fitted to the nut 25 so as to face the gap. Provided, said
A position corresponding to the nut supporting screw hole 26 of the vertical portion 31.
At the same time, a nut fixing screw 34 is screwed into the nut supporting screw hole 26 from the vertical portion 31 side to form a fool hole 33 for fixing the nut 25 in the nut fitting groove 24.
The vertical portion 31 corresponds to the rail holding screw hole 27.
At the position, insert the rail fixing screw 35 from the vertical part 31 side.
A fool hole for fixing the upper rail 5 to the channel material 1 by screwing and screwing into the screw hole 27 for holding the rail.
33 is a mounting device for an upper rail, which is formed by drilling 33 .

[0007]

[Action] by fitting a nut 25 at predetermined intervals in the nut fitting groove 24, screwed lightly nut fixing screw 34, the nut 2
5 can slide in the nut fitting groove 24.
When mounting or replacing the upper rail 5, the vertical portion 31 of the upper rail 5 is inserted from below into the engaging portion 20, and the locking step 32 of the upper rail 5 is locked to the locking portion 23. And <br/> Te, nuts rail fixing screw 35 through clearance hole 33 2
5 is screwed into the rail holding screw hole 27 of the upper rail 5.
Is fixed to the channel material 1. Further, the nut fixing screw 34 is screwed into the nut supporting screw hole 26 from the fool hole 33 side , and the nut 25 is fixed to the nut fitting groove 24. The mounting method is the same whether the upper rail 5 is the built-in upper rail 5a or the direct mounting upper rail 5b.
