DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic perspective view of a double-glazed glass according to the present invention. In the double-glazed glass 1, a metal or resin including a moisture absorbent (not shown) is appropriately included in the entire inner periphery of the glass plates 3, 3. The inner space 4 is formed by interposing a spacer 2 made of the same. A blind box 5 made of metal, resin, or the like is disposed in the upper portion of the double-glazed glass, and a driven shaft, a driven rotating plate, a rotating shaft for blind operation, and the like, which will be described later, are accommodated in the blind box.

At the upper end of the double-glazed glass 1, a cylindrical sheath 9 made of resin, non-magnetic metal (for example, aluminum) or the like is fixed to the glass plate 3 and fixed and supported by the sheath. A vertically protruding operation shaft 10 is arranged, and a rotary operation panel 11 made of resin, non-magnetic metal (for example, aluminum) or the like is rotatably supported on the operation shaft 10. The operation string body 11a is wound around the rotary operation panel 11, and the rotation operation panel 11 is also rotated by moving the string body up and down.

A plurality of blind slats 8 are laid on ladder-shaped cords (hereinafter referred to as ladder-shaped cords) 6 and 6 for adjusting the slat angle in the inner space 4 of the double-glazed glass. Reference numeral 8 denotes a slat lifting / lowering cord (hereinafter, referred to as a lifting / lowering cord) 7 which is inserted into the slat lifting / lowering cord 7 so that the slat can be raised / lowered.

FIG. 2 is a partial schematic plan sectional view showing a worm gear mechanism as a preferred example of an interlocking rotation mechanism and a rotation transmission mechanism, which traverses a portion where the operation shaft of the double-glazing is located. 3 is a partial schematic perspective view showing the relationship between the interlocking rotation mechanism and the worm gear mechanism (the cylindrical sheath and the rotary operation panel are shown separately. Peripheral members are not shown).

The blind box 5 made of resin, metal or the like in the multi-layer glass 1 has a front wall 5a, a rear wall 5b,
It consists of a bottom wall 5c and a ceiling wall 5d (see FIG. 6). In addition, the ceiling wall 5d is provided with a function as a spacer (interior / outside space blocking wall) in place of the upper side spacer 2a (see FIG. 1) in the multilayer glass 1, and the upper side spacer can be omitted. The other walls 5a, 5b, 5c do not necessarily need to adopt a wall structure, and fix various bearings and shafts described later,
What is necessary is just to have a frame structure which can be supported.

The portion of the blind box front wall 5a facing the rotary operation panel 11 is cut off. On the outside of the glass plate 3, a rotary operation panel 11 passing through an operation shaft 10 is arranged,
On the side facing the glass plate 3, a plurality of magnets 11b are arranged around the axis like N pole, S pole, N pole --- so that the operation cord body 11a can be wound around the outer periphery of the rotary operation panel. Then, the rotary operation panel itself is used as a pulley.

The operating shaft 10 is attached to a cylindrical sheath 9 disposed so as to cover the outer periphery of the rotary operation panel 11. Radial pieces 9a extending from the central portion are arranged, and are formed so as to project vertically outward from the glass plate surface from the central portion. The cylindrical sheath 9 has a string insertion hole 9 through which the operation string 11a is inserted.
Distribute b.

The cylindrical sheath is not limited to the above, but also covers, for example, the outer surface (non-magnet exposed surface) of the rotary operation panel, and the operating shaft projects vertically from the center of the coated surface toward the glass plate surface. Alternatively, a rotary operation panel may be mounted on the operation shaft through the shaft.

On the rear wall 5b of the blind box in the double glazing, a driven shaft 14 is provided to project perpendicularly to the wall surface (glass plate surface). The driven shaft 14 is coaxial with (extends from) the operating shaft 10, and a driven rotating disk 12 made of resin, non-magnetic metal (for example, aluminum) or the like is rotatably mounted on the driven shaft. The driven rotary disk 12 has magnets 12a arranged around its axis on the side facing the glass plate 3 as S, N, and S poles, and its outer periphery forms a tooth shape 12b. Do it with the worm itself.

The blind box 5 has a rotating shaft 13 for blind operation parallel to and horizontal to the surface of the glass plate.
Is horizontally suspended between a plurality of bearings 16a (only one is shown in the figure) provided on the bottom wall 5c, for example, and is rotatably supported. The blind operating rotary shaft 13 is provided with a worm wheel tooth profile 13a and meshes with the worm tooth profile 12b of the driven rotary disk 12, thereby forming a worm gear mechanism.

That is, by raising and lowering the operation cord 11a, the rotary operation panel 11 is rotated, and with the rotation, the driven rotary disk 12 is rotated by a magnetic attraction action.
The rotation of the rotating shaft 13 for blind operation is converted by the worm gear mechanism.

FIGS. 4 and 5 are views showing a form in which a bottomed cylindrical sheath made of resin, a non-magnetic metal (for example, aluminum) or the like is provided instead of the cylindrical sheath in FIGS. 2 and 3. FIG.
Is a plan sectional view corresponding to FIG. 2, and FIG. 5 is a perspective view corresponding to FIG.

The glass plate 3 is previously hollowed out, and the bottom portion 9'a of the bottomed cylindrical sheath 9 'penetrates the glass plate hollow portion and is disposed on the inner side of the glass plate. The bottom flange 9'b (hatched portion in FIG. 5) is tightly adhered to the perforated peripheral portion of the glass plate, and the perforated portion is sealed with a sealing agent or the like, thereby impairing the sealing of the internal space. Not to be. While the thickness of the glass plate 3 is, for example, 3 mm or 5 mm, the thickness of the bottom 9 ′ a can be reduced to, for example, 0.2 to 0.3 mm to 1 mm or less. As a result, the magnets of the driven rotary disk 12 come close to each other, and the mutual magnetic attraction action also increases. Alternatively, a cheaper magnet having a weak magnetic attraction can be employed.

From the center of the bottom of the bottomed cylindrical sheath 9 ',
An operation shaft 10 is protruded, and the operation shaft 10 is inserted through a rotary operation panel 11 '. The magnet arrangement of the rotary operation panel 11 'is the same as that of the rotary operation panel 11. In the figure, a form is shown in which a pulley portion 11'a is attached and fixed outside the rotary operation panel 11 '(on the front side in the figure) and the operation cord body 11a is wound.
As in the case of the rotary operation panel 11, it is needless to say that the rotary operation panel 11 'itself may be used as a pulley, and the operation cord 11a may be wound around the outer periphery of the pulley. The configurations of the driven rotary disk, the worm carrier structure, and the rotating shaft for blind operation on the closed space side are the same as those in the previous example.

FIG. 6 shows a rotary shaft for blind operation.
It is the partial schematic perspective view which showed the raising / lowering of a blind slat, and the angle adjustment mechanism. In the figure, an auxiliary winding shaft 15 is fixedly provided by a plurality of bearings 16b (only one is shown in the figure) projecting below a ceiling wall 5d of a blind box 5 (shown by a broken line). Further, a pulley 15a is rotatably provided around the auxiliary winding shaft 15. The lifting / lowering cord 7 is previously wound around the blind operating rotary shaft 13 and the pulley 15a, so that the blind operating rotary shaft 13 and the pulley 15a Wrap around.
For example, when the elevating cord 7 is wound only on the rotating shaft 13 for blind operation, the cord wound body becomes thick, and when the gap between the glass plates (closed space layer) is narrow, there is a fear that the cord cannot be wound. Such a design can eliminate such fears.

A torsion spring 13b is separately wound around the blind operating rotary shaft 13 and tightened.
At 13c, a pair of cords of the ladder-shaped cord 6 are respectively suspended. As one of the arms of the torsion spring is raised and the other is lowered with the rotation of the blind operating rotary shaft 13, the opening / closing angle of the slat 8 spanning the ladder-shaped cord 6 changes. By contacting the arm support 13c with a stopper (not shown), the tightening of the spring is released, and excessive opening and closing is suppressed.

FIG. 7 is a partial schematic perspective view showing another lifting / lowering mechanism of a blind slat using a rotating shaft for blind operation instead of the embodiment shown in FIG.

A worm wheel tooth profile 13c is provided around the blind operating rotary shaft 13, and a worm 17 having an axis perpendicular to the surface of the glass plate is separately provided to mesh with the worm wheel tooth profile 13c. Cord winding shaft perpendicular to the glass plate surface with twin gears (both wheels) meshing with worm 17
By arranging 18, the lifting cord 7 is wound around the cord winding shaft 18 by the rotation of the blind operating rotation shaft 13,
Try to rewind. The elevating cord 7 is wound around a cord winding shaft 18 via a pair of nipping rollers 19, a drum-shaped roller 20 for converting the suspended elevating cord 7 in a horizontal direction, and a pair of nipping rollers 21. In changing the direction, the direction changing means is not specified, such as using a sandwiching roller instead of the hourglass roller 20. Although not shown, the worm 17, the cord winding shaft 18, the holding rollers 19 and 21, the hourglass roller 20 and the like are rotatably mounted on the front wall, the rear wall, or the bottom wall of the blind box, respectively. It is supported.

The blind slats 8 are made of not only light-shielding (light-absorbing and reflecting) materials made of opaque resin, ceramics, metal, etc., but also light made of transparent resin, glass (including those obtained by applying paper, cloth, etc. to them). Permeation suppression materials, heat insulation materials,
Either a sound insulating / sound absorbing material or a composite material thereof can be employed. For example, a translucent material, a heat ray absorbing material, a heat ray reflecting material, a low heat radiating material, a heat insulating material having fine pores, a sound absorbing material, etc. are applied. be able to.

For example, the application of a film made of a translucent material, a heat ray absorbing material, a heat ray reflecting material, or a low heat radiation material to a blind slat made of transparent clear or colored resin or glass is also within the scope of the present invention.

The blind slat 8 can have various shapes such as a triangular cross section, a quadrilateral shape, a circular shape, an elliptical shape, a semicircular shape, and furthermore, a surface having irregularities. Designs such as devising reflection and refraction directions are also possible.

Further, without using blind slats,
A roll-type curtain blind or a foldable curtain blind is adopted as a rotating shaft for blind operation via a hanging cord, and the blind is raised and lowered by winding and unwinding the hanging string, which is also within the scope of the present invention.

According to the present invention, for example, a 14-18 mm thin double-layered glass in which a pair of 2-3 mm-thick glass is provided with an internal space layer having a thickness of 10-12 mm can be inserted into a standard sash. It has the feature that it can be made compact and has excellent appearance.
