Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a main part of the embodiment. FIG. 1 shows an example in which the present invention is applied to an internal sash or a semi-internal sash. Hereinafter, this will be described. The same reference numerals are used for members that are the same as or correspond to those of the prior art shown in FIG.

The window frame WF has an upper frame 1 similar to a conventional window frame.
, The lower frame 2 and the left and right vertical frames 3 are assembled in a rectangular shape. The shutter mounting frame SF is formed as a single frame by connecting the upper frame 4a, the lower frame 4b, and the left and right side plates 4c in a rectangular shape. Upper frame 4 of shutter mounting frame SF
The upper end of the cover body 5 is fitted to the outdoor end of the upper frame 4a at the outdoor end of the upper frame 4a, and is screwed at a required position, and the cover body 5 is attached so as to be openable and closable. A storage space 6 is formed. The structure for attaching the cover body 5 to the upper frame so as to be openable and closable is not limited to that shown in the figure. For example, the upper end of the cover body 5 may be rotatably connected by a hinge or the like, and the cover body 5 may be rotatably connected to the hinge so that the cover body 5 can be opened and closed.

The shutter 5 is provided in the shutter storage space 6.
The winding drum 55 on which the roll 6 is wound is supported by the side plate 4c via the reinforcing attachment member 4d and the bracket 59, and the winding drum 55 is rotated forward or backward through a motor (not shown). I have.

A pair of inner and outer protruding edges 31, 32 are provided on opposing surfaces of the window frame WF at the outdoor side ends of the two vertical frames 3, between which the two vertical frames are open in directions facing each other, and A slat guide rail 30 (hereinafter simply referred to as a guide rail) having a groove 33 continuous in the longitudinal direction of the vertical frame is provided.

In the sash with shutter according to the present invention, before the window frame WF is mounted on the building, the shutter mounting frame SF is integrally connected to the window frame WF. That is, the shutter mounting frame SF is formed in a rectangular shape by the upper frame 4a, the lower frame 4b, and the both side plates 4c, and is connected to the bottom of the lower frame 4b and the upper portion of the upper frame 1 of the window frame WF. For example, the fitting groove of the locking groove 101 and the locking piece 102 and the screw receiving groove 1
For example, the screw 104 is screwed into the window frame WF so as to be integrally connected to the window frame WF before being attached to the building. Thereafter, the winding drum 55 around which the shutter 56 has been wound is rotatably mounted on the support shaft 58 in the shutter storage space 6, and the cover body 5 is mounted.

Between the lower end 5a of the closed cover body 5 and the outdoor end of the upper frame 1 of the window frame, a width substantially equal to the distance between the protruding edges 31, 32 forming the guide rail 30 is provided. In addition, a continuous gap 7 is formed between the two vertical frames. And
The upper end of the guide rail 30 faces the shutter housing space 6 from between the longitudinal end of the lower end 5a of the cover body 5 and the outdoor end of the longitudinal end of the upper frame 1.

The distance between the bottoms of the grooves 33 of the guide rail 30 which are open to face each other is set to be slightly larger than the width of the slat 56a wound around the winding drum 55, and the motor for opening and closing the shutter is rotated forward. In this case, both ends of the slats 56a unwound from the winding drum 55 are guided by the guide rails 30, descend the outdoor surface of the window formed by the window frame WF, shield the window, and reverse the motor. In this case, the slats 56a covering the window are wound on the winding drum and guided by the guide rails 30 to rise and open the window as in the conventional case.

Since the upper end of the guide rail 30 is cut off above the upper frame 1 and the lower frame 4b, the slats 56a can be wound around the winding drum 55 and unwound. Further, an upper end portion 3 of a protruding edge forming the guide rail.
Since 1a and 32a are spread upward in a trumpet shape, the slats 56a can smoothly enter the guide rails 30. Each of the protruding edges 31 and 32 has a groove (not shown) which is open at a front end thereof, facing each other, and a gap closing member (not shown) such as mohair is mounted in the groove.

Since the support shaft 58 of the winding drum 55 is provided on the indoor side of the guide rail 30, that is, within the width of the vertical frame, from the outer wall W to the outdoor end (projecting edge) of the vertical frame 3. Has the advantage that the amount of protrusion of the shutter mounting frame SF from the outer wall W (the distance from the outer wall to the outdoor side surface of the cover) can be minimized.

In this embodiment, the cover body 5 is attached to the outdoor side of the winding drum 55 so as to be freely opened and closed,
5, a lid plate 8 is detachably mounted between the indoor end of the upper frame 4a or the side plate 4c and the indoor end of the lower frame 4b. The cover plate 8 is formed of a known material having heat insulation performance and soundproof performance, and has locking grooves 81 formed at a plurality of upper and lower locations on the outdoor surface. Further, a spring-like locking piece 83 is attached to a supporting member 82 connected to the side plate 4c, and the lid plate 8 approaches the shutter mounting frame at a position where the upper end thereof contacts the upper end of the window opening O. By moving the cover plate 8 downward in a state where the stopper 83 is fitted to the lower end of the groove 81, the stopper 83
Is locked to the upper end of the groove 81 and fixed.

Airtight members 9 protruding in the indoor direction are fitted to the indoor end of the upper frame 4a, the indoor end of the lower frame 4b, and the indoor end of the side plates 4c, respectively. When the locking piece 8 is fixed to the locking piece 83, the locking piece is urged in the outdoor direction by the spring restoring force of the locking piece, so that the outdoor side surface of the lid plate 8 abuts on the airtight member, and the shutter mounting frame SF and A soundproofing effect and a heat insulating effect are secured between the room and the room.

Further, since the cover plate 8 can be easily removed by moving in the opposite direction to the mounting,
When a minor repair (repair that can be performed without removing the shutter component 56a from the shutter device) is required for the shutter component 56a or the motor, the cover plate 8 is easily removed from the indoor side to quickly and easily perform the repair. It can be carried out. Remove the cover body 5 from the outdoor side or open it,
When performing maintenance such as repair and maintenance, when the window is on the upper floor, there is a danger such as a fall accident. However, in the sash according to the present embodiment, maintenance cannot be performed unless the cover body 5 is opened. The cover body 5 may be opened or removed only in such a limited case, so that the danger such as a fall accident is prevented or reduced.

Since the support shaft 58 of the winding drum 55 is installed on the indoor side of the guide rail 30, that is, within the width of the vertical frame 3, the winding drum 55 can be stored above the upper frame 1. In addition, since the distance from the indoor side end of the window frame WF to the guide rail 30 can be made as small as possible, the amount of protrusion of the shutter mounting frame SF from the outer wall W is small, and the appearance of the sash with shutter is improved. improves.

In FIG. 1, the support shaft 5 of the winding drum 55 is shown.
8 is fixed to the vertical frame 3, but when the side plate 4c has a sufficient strength, the side plate 4c may directly support the spindle 58 of the winding drum. In that case, the locking piece 83 can also be fixed to the indoor side end of the side plate 4c.

The cover plate 8 connects the shutter mounting frame SF to the window frame W.
F, or after attaching the window frame WF integrally joined with the shutter mounting frame SF to the opening O of the building,
It is detachably attached to the shutter attachment frame SF.

In the above embodiment, the shutter mounting frame can be mounted at the time of assembling the sash window frame. If the sash window frame is mounted on the building in the same manner as before, the shutter mounting frame can be mounted at the same time. In addition, the required time is significantly reduced, and the construction cost is reduced.

This embodiment, particularly when applied to a semi-external sash or an internal sash, makes it possible to easily perform maintenance such as repair and maintenance of shutter components from either the inside or the outside as necessary. Has advantages.

[0026]

As described above, according to the present invention, the shutter mounting frame is integrally connected to the window frame before the window frame is mounted on the building. The mounting frame is also mounted at the same time. Therefore, the man-hours and time required for installation to the building are significantly reduced. Also, since the shutter mounting frame is assembled independently of the window frame, if the diameter of the winding drum differs according to the height of the window, that is, the length of the shutter, select a shutter mounting frame of appropriate dimensions. By simply connecting to the same window frame, various shutters can be easily handled. Since the shutter mounting frame is assembled independently of the window frame, the window frame can be mounted on a building like a normal window frame without connecting the shutter mounting frame thereto. In the shutter storage space, the cover body is attached to be openable and closable on the outdoor side, so that maintenance work of the shutter can be easily performed from the outdoor side as needed. Since the rotation axis of the winding drum is provided on the indoor side of the slat guide rails, that is, within the width of the vertical frame, the amount of protrusion of the shutter mounting frame on the outdoor side can be reduced, and the appearance of the sash with shutter is further improved. improves.

When the lid plate is detachably mounted on the indoor side of the shutter mounting frame, when minor maintenance of the shutter is required, the lid plate is removed from the indoor side to perform the maintenance work safely and easily. be able to.
