Reference numerals 62a and 63a are screw holes formed in the abutting pieces 62 and 63, and the screw holes 62a and 63a are used to maintain the abutting state by using screws (not shown).

The base of the bearing fitting 6 is pivotally attached to the vertical frames 4, 4 so that the bearing fitting 6 can be rotated in the front-rear direction of the sash frame 1.

In the embodiment, the bearing fitting 6 is mounted on the vertical frame 4 via the mounting plate 7, and is further configured to control the rotation in the front-rear direction.

Specifically, screw holes 71 for fastening to the vertical frame 4 are formed in the upper part and the lower part of the mounting plate 7, and the base part of the above-mentioned bearing fitting 6 is pivotally attached to the upper part of the mounting plate 7. A base portion of a stopper rod 8 having a stopper piece 81 at its tip is pivotally attached to the lower portion of the mounting plate 7, and a base portion of a connecting rod 9 is pivotally attached to the tip end of the stopper rod 8. The tip portion of 9 is pivotally attached to the tip portion of the bearing fitting 6.

Therefore, the tip of the bearing fitting 6 is connected to the lower portion of the mounting plate 7 via the connecting rod 9 and the stopper rod 8 that form a so-called link. Reference numeral 10 denotes a spring arranged at a pivotally connecting portion between the stopper rod 8 and the connecting rod 9, and the spring 10 plays a role of urging the bearing fitting 6 in a direction to be superimposed on the mounting plate 7 side. The stopper piece 81 plays a role of maintaining a constant opening between the bearing fitting 6 and the mounting plate 7.
Reference numeral 72 is a stopper projection piece that receives the back surface of the stopper rod 8.

In the above-mentioned bearing fitting, the stopper rod 8 is rotated counterclockwise with respect to the mounting plate 7 at the time of carrying a shutter which will be described later, and accordingly, the connecting rod 9 is rotated clockwise with respect to the stopper rod 8. 6 is rotated clockwise with respect to the mounting plate 7, and as a result, the metal fitting 6 is housed in the mounting plate 7 as shown in FIG.

Of course, the sash frame 1 of the present invention may be attached with other components usually provided. For example, as shown in FIG. 3, the drainage component 11 may be attached to the lower surface of the upper frame 2.

The shutter chamber 12 for accommodating the shutter 20 is formed by attaching the shutter covers 13 and 14 shown in FIGS. 4B and 4C to the upper front part of the sash frame 1. The shutter cover 13 is for receiving eaves, and the shutter cover 14 is for receiving with a wall. The lower portions of these shutter covers 13 and 14 are plate members bent in an L shape as shown in FIG.
5 "), and a skirting board 1 arranged in front of the eyeless 5
Mounted on 6. 15a is a hole formed for attaching the metal fitting 15 to the baseboard 16, 15b is a hole formed for attaching the shutter cover 13 or 14, and 15c is a hole formed for attaching a stopper 19 described later. On the other hand, in the case of the shutter cover 13, a hook 13a is formed on the upper portion thereof, and the hook 13a is configured to be hooked on the hooking protrusion 2a formed on the upper frame 2. Further, in the case of the shutter cover 14, an elastically deformable elastic ring 14a is formed on the upper part thereof, and the elastic ring 14a is attached to the wall 17
It is provided in such a configuration that it is press-fitted into and locked by an insertion hole formed in the upper frame 2 fitted just above.

In the shutter chamber 12 thus formed, the bearing fitting
When the shutters 6 and 6 and the shutter 19 described later and the shutter 20 are electric, the electric motor 18 directly attached to the vertical frame 4 is housed. Reference numeral 19 is a stopper fixed to the rear surface of the skirting board 16, and the stopper 19 plays a role of limiting the winding amount of the shutter 20 so as not to be excessive.

Next, the shutter housed in the shutter chamber 12 described above.
20 will be described. Reference numeral 20a indicates a shutter winding shaft.

At both edges of the shutter winding shaft 20a, a corner forming metal fitting 21 for non-rotatably gripping the bearing fitting 6 and a reverse rotation preventing fitting 22 described later is bolted. As shown in FIG. 6 (b), the corner portion forming metal fitting 21 is formed by bending a plate-like material into a U-shape in a side view, and has bolt through holes 21a, 21a formed on the upper and lower surfaces thereof. There is.

Further, a sprocket 20b is mounted on the shutter winding shaft 20a, and a chain 23 is hung between the sprocket 20b and the rotation transmission shaft 18a of the motor 18. Further, the reverse rotation preventing metal fitting 22 is a long plate-like member in which a rising portion 22b is formed at the upper end of the central inclined portion 22a and a hanging portion 22c is formed at the lower end, and a reinforcing rib 22d is provided at the center. , And the rising part 2
2b includes a claw 22e that engages with the back wall of the corner forming bracket 21.
In addition, the hanging portion 22c has a claw 2 that engages with the fitting 15.

That is, at the time of factory assembly, the stopper 19 is not yet attached to the skirting board 16, and the shutter 20 is held not by the bearing fitting 6 but by the reverse rotation preventing fitting 22. Therefore, at the time of transportation after assembling, the shutter 20 is supported by the holding portion 6a of the bearing fitting 6, the stopper 19 is attached to the fitting 15, and then the reverse rotation preventing fitting 22 is removed. Then, the shutter 20 is expanded to reduce the winding amount (reducing the diameter), and the bearing metal fitting 6 is pushed toward the mounting plate 7 side (see FIG. 2B), and the sash frame 1 is made as flat as possible. Take the form and use it for transportation. Of course, in the field assembly, the reverse operation to the transportation is performed.

(Effects of the Invention) Since the present invention is configured as described above, the bearing fitting can be rotated in the front-back direction of the sash frame, and the rotation amount is limited by the stopper rod having the link function. Therefore, the bearing fitting can be projected to the front surface of the sash frame so that the shutter is not in use, and conversely, the bearing fitting can be rotated to a position near the rear portion of the sash frame to be in a storage state suitable for transportation. Easy on-site assembly.
