A part of the rotating string 40 is stretched along the side edge and is fixed to a rotating string attachment protrusion 24 that protrudes on the side opposite to one of the fitting protrusions 21 of one of the string guides 20. .

As shown in FIGS. 7 to 10, the rotating tool 50 includes a groove wheel 56 around which the rotating string 40 is wound, and an operating lever as a rotating member that is pivotally supported to rotate the groove wheel 56. 58, and a one-way spring clutch which connects the groove wheel 56 and the operating lever 58 so that the groove wheel 56 can be rotated only when the operating lever 58 is turned.

That is, the rotating tool 50 has a shaft portion 52 protruding from the bracket plate 51, a coil spring 53 having engaging folded pieces 53A at both ends is externally fitted onto the shaft portion 52, and is attached to the bracket plate 51 concentrically with the coil spring 53. ,
The holding frame 54 pivotally supports the engagement tube 55 and the groove wheel 56, and when the groove wheel 56 rotates, it comes into contact with each engagement folded piece 53A of the coil spring 53, and the coil spring 53 is attached to the shaft portion 52. An engaging portion 56A is formed to be tightened and fixed, and a square hole 55B is formed in the holding frame exposed surface of the engaging tube 55.
When the coil spring 53 rotates, the engaging folded piece 53 of the coil spring 53
The coil spring 53 is brought into contact with each of the shaft portions 52
An engaging portion 55A is formed in which the groove wheel 56 is rotated via the engaging folded piece 53A of the coil spring 53 and the engaging portion 56A of the groove wheel 56, respectively. Rotating member mounting shaft 57 with square pin 57A protruding from square hole 55B of engagement tube 55
is rotatably arranged, and a crank-shaped operation lever 58 is connected to this square pin 57A.

Furthermore, the rotating member of the rotating tool 50 may be provided with an operating pulley 60 instead of the operating lever 58, as shown in FIG. An annular operating string 61 is wound around the operating pulley 60 in this case. In addition to the operation string 61 that is arranged by a pulley 62 or the like inside the double-glazed window F so as to be parallel to the rotation string 40 as shown in FIG. In some cases, an operating pulley (not shown) is provided in place of the operating lever 58 of the tool 50, and the device is suspended by being wrapped around the operating pulley.

By the rotation of the rotation string 40, the edge fixture 10 moves downward and the screen S is unwound. The elastic force of the torsion coil spring of the roll screen body 1, the weight of the screen S, etc. act on the edge fixing device 10 fixed to the leading edge portion of the unrolled screen S, and the edge fixing device Try to move 10 downward. In other words, although an attempt is made to rotate the groove wheel 56, since the coil spring 53 is tightly wound and fixed to the shaft portion 52, the groove wheel 56 cannot be rotated and remains in a stopped state. Therefore, the edge fixture 10 can be stopped at the unwound position.

In addition, 54A in the figure is a rotation guide protrusion for rotating the groove wheel 56 within the holding frame 54, and this rotation guide protrusion 54A is inserted into a concentric circumferential groove 56B formed on both sides of the groove wheel 56. The groove wheel 56 is made rotatable.

Protrusions are provided alternately at equal intervals along the length direction of the groove 56C, and both wall surfaces having the protrusions grip the rotating string 40 disposed in the groove 56C from both sides to prevent slipping. It is set as 56D. Furthermore, 59 in the figure is
This is a pivot ring arranged to facilitate rotation of the engagement cylinder 55. The engaging portion 55A of the engaging tube 55 and the engaging portion 56A of the groove wheel 56 are formed by protruding from the groove wheel 56, as shown in FIGS. Although provided by forming the engaging portions 55A and 56A, the shape and number of the engaging portions 55A and 56A are not particularly limited.

Furthermore, in the illustrated example, the engaging portion 55A of the engaging cylinder 55 is disposed within the inner circumferential surface of the groove wheel 56;
If it engages with the engagement folded piece 53A of the coil spring 53 externally fitted on the shaft portion 52, the engagement tube 55
An engaging portion (not shown) may be formed protruding from the inner circumferential surface, and an engaging portion (not shown) of the groove wheel 56 may be disposed within the engaging tube 55. Of course. In short, the engaging portion 56A of the groove wheel 56 is
It is sufficient that the coil spring 53 is tightened and fixed to the shaft portion 52 when engaging with the engagement folded piece 53A of the coil spring 53, and the engagement portion 55A of the engagement tube 55 is When engaging the folding piece 53A, the coil spring 53 is inserted into the shaft portion 52.
Any device that can be rewound and released from the beginning is fine.

Although one roll screen device R and one moving means D are disposed in the double-glazed window F, the roll screen device R and the moving means D are not limited to a single unit, and a plurality of roll screen devices R and moving means D may be disposed. For example, a roll screen main body 1 having a screen S that completely blocks the amount of light
and a roll screen main body 1 having a screen S (so-called Venetian blind type) with a rough weave to adjust the amount of incident light and soften the incident light rays, and select one of the screens S. It may also be something that can be stretched.

(Effects of the Invention) Therefore, the present invention uses a roll screen main body 1 equipped with a winding tube T that can be rolled up and unwound by the elastic force of a built-in torsion coil spring to be used as a window of a double glass window F. It is installed inside the frame F2 via a bracket B, and a cylindrical edge fixture 10 parallel to the cylindrical center of the winding tube T is fixed to the tip edge of the screen S of the roll screen body 1. , near both ends of the winding tube T, the base end portions of two guide strings 30 are respectively fixed, and these guide strings 30
are arranged parallel to each other along the side edges of the screen S up to the edge fixtures 10, and the edge fixtures 1
Each of the guide strings 30 is inserted into the edge fixture 10 from both open ends of the edge fixture 10, crossed within the edge fixture 10, and led out to the opposite side, and these led out guide strings 30 are unwound. Window frame F2 so that it becomes parallel again along the extension direction of the side edge of the screen S
The guide strings 30 are provided up to a pulley 31 which is pivotally supported by the pulley 31, and the tips of the guide strings 30 are connected and stretched to a tensioning means 32 via the pulley 31. String guide device 2 equipped with a pulley 23 that movably guides a book guide string 30
0 respectively, and by moving the edge fixture 10 away from and approaching the winding tube T, the screen S can be rolled up.
A roll screen device R that can be freely unrolled is formed, and a loop-shaped rotating string 40 stretched in parallel along the side edge of the screen S is fixed to one of the string guides 20. A moving means D is formed by attaching a rotating tool 50 equipped with a one-way clutch to a moving string 40, and the roll screen device R and moving means D are arranged in double layers on a frame F2 with glass F1. Conventionally, the rotating member for operating the rotating tool 50 of the moving means D is arranged outside the double-glazed window F. Therefore, the roll screen device R, whose mounting position was limited, can be mounted freely in the tensioning direction with a simple configuration. In other words, it is possible to extend a screen S disposed in a vertical plane upwardly or laterally, or to extend a screen S disposed in a horizontal plane horizontally. Moreover, although the configuration is simple, consisting of the pair of guide strings 30 and the string guide 20, the edge fixing device 10 can always be moved parallel to the cylinder center of the winding tube T of the roll screen main body 1. . Therefore, there is no risk of deflection winding when winding the screen S into the winding tube T, and there is no occurrence of winding misalignment such as rubbing the side edge of the screen S against the bracket B. In addition, since the roll screen main body 1 has a built-in torsion coil spring, the unrolled screen S is always stretched by the elastic force of the torsion coil spring and does not bend, so that it can be placed inside the double-glazed window F. It is also possible to do so.

Further, each guide string 30 has its proximal end portion fixed near both ends of the winding tube T, and its distal end portion connected to the tensioning means 32, so that the guide string 30 can be kept stretched at an appropriate tension state at all times. This improves the accuracy of translation of the edge fixture 10. And string guide 2
Since the pulley 23 is provided at 0, the edge fixture 10 can be moved in parallel even more smoothly and reliably.

Further, a loop-shaped rotating string 40 stretched in parallel along the side edge of the screen S is fixed to one string guide 20 of the edge fixture 10, and this rotating string 4
Since the moving means D is formed by attaching a rotating tool 50 equipped with a one-way clutch to the rotating tool 50, the loop-shaped rotating string 40 can be rotated by the rotating tool 50.
Ensure that the edge fixture 10 is moved and the screen S
You will be able to unwind and rewind. Moreover,
Since the rotating tool 50 is equipped with a one-way clutch,
The screen S can be stopped at the unwound position without moving or being caught by the weight of the unwound screen S or the elastic force of the built-in torsion coil spring. Furthermore, unlike other locking means such as a ratchet wheel, it can be stopped at any position, rather than at intermittent stopping positions. In addition, unlike locking means such as a ratchet wheel, there is no risk of generating abnormal noise when locking or releasing the lock.

In particular, the loop-shaped rotating string 40 is
Since it is stretched in parallel along the side edge of the cord and is fixed to one of the string guides 20 of the edge fixture 10, when the screen S is rolled up, that is, when the screen S is not stretched, There is no risk that the rotating string 40 will be exposed on the surface on which the screen S is stretched, and the appearance will be good.

Since the roll screen device R and the moving means D are arranged inside a double glass window F which is made by doubling the glass F1 on the frame F2, it can be used as a double window body with a built-in roll screen device R. It is possible to bring completeness to the product. That is, troublesome work such as on-site installation adjustments can be eliminated, and there is no difference in installation from conventional window bodies, etc., and work efficiency is improved. Furthermore, since the screen S is not stretched over the surface of the window body as in the past, there is no risk of the screen S being contaminated by indoor air, and the appearance is also very good. becomes. In addition, since it is a double-walled glass window, it is naturally possible to improve heat retention and soundproofing, and it becomes possible to easily provide a double-walled glass window that also has a light-shielding function.

Furthermore, since the rotating member that operates the rotating tool 50 of the moving means D is disposed outside the double-glazed window F, the unwinding and winding operations of the screen S can be performed very easily and reliably. . In addition, the rotating members of the rotating tool 50 include an operating lever 58, an operating knob 63 connected to the operating pulley 60, and an operating string (not shown) that is wrapped around the operating pulley and suspended outside the window frame F2. By selecting the above, it becomes possible to diversify the operation, and it is convenient because the rotating member can be arbitrarily selected depending on the installation location, etc.

As explained above, according to the present invention, it is possible to provide a double-glazed window body with a built-in roll screen device that can be freely attached to any wall surface, roof, etc., and can also freely set the direction in which the screen is stretched. Moreover, the structure is simple, and various excellent effects can be expected, such as not only the screen will not be contaminated by indoor air, but also a good appearance.
