DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-glazed glass blind device.

[0002]

2. Description of the Related Art As a conventional blind device incorporating a double-glazing unit, there is the following one. For example,
No. 5996 discloses an upper hanger member and a lower hanger member which are respectively supported by bearings above and below the inside of a double glazing constituted by a pair of glass plates provided on a rectangular frame. It is rotatably supported. The upper hanger member and the lower hanger member respectively support band cables that support a plurality of small plates (slats). The band cable is connected to the operating member by two linear members. The operating member is vertically movable on the inner surface of the glass plate and is magnetically connected to a starting member that moves linearly in a slide fixed to the outer surface of the glass. The upper hanger and the lower hanger are rotatable by moving the activation member up and down. Japanese Unexamined Utility Model Publication No. Sho 62-91895 discloses a rotary glass having a pair of glass plates provided on a frame of a square frame-shaped spacer and having a horizontal rotation at an upper portion inside a double glazing. The shaft is attached, and both ends of the horizontal rotating body are attached to the lower spacer. A plurality of ladder cords supporting a large number of slats are stretched between the horizontal rotation axis and the horizontal rotation body so as not to slide relative to the horizontal rotation axis. The horizontal rotating shaft is rotatable by raising and lowering a driving force transmitting member led out from near the center thereof. The driving force transmitting member is moved up and down by vertically moving a driving permanent magnet that is integrally and movably attracted to a driven permanent magnet provided on the driving force transmitting member from an outer surface of the glass plate.

[0003]

However, the above-mentioned conventional blind device with a built-in double-layer glass has the following problems. That is, both the upper hanger (horizontal rotating body in Japanese Utility Model Laid-Open No. 62-91895) and the lower hanger (Japanese Utility Model Application Publication No. 62-9189
In Japanese Patent Application Publication No. 5 (1993), since the dimension between the belt cable and the horizontal cable is fixed, the band cable (Japanese Utility Model Application Laid-Open No. 62-91895) is stretched by its own weight.
The ladder code described in Japanese Patent No. 91895 is slack between them. For this reason, when the small plate (slat) is rotated, the upper hanger (horizontal rotating body) and the lower hanger (horizontal rotating body) can be moved even if the starting member (driving permanent magnet in Japanese Utility Model Laid-Open No. 62-91895) is moved. The shaft) cannot obtain a rotation amount corresponding to the movement amount of the starting member (drive permanent magnet) due to the slack of the cable (ladder cord).
For this reason, there is a problem that the small plate (slat) does not enter the fully-closed state or the fully-opened state even when the actuating member (driving permanent magnet) is moved to the end. The present invention is to solve such a problem.

[0004]

The object of the present invention is to provide a rotary drum connected to a ladder cord via a rotary shaft with a spring for urging the rotary drum to always rotate in the operation cord winding direction. Solve. That is,
The blind device with a built-in double-glazed glass of the present invention is provided inside a double-glazed glass configured by a pair of glasses being provided in parallel with each other with a frame having a rectangular cross section sandwiched from both sides. A head box attached to the inside of the frame, a number of slats supported in alignment by a ladder cord, and a bottom rail arranged at one end of the slat row, one side of the slats The ladder cord has a magnetic body attached to it, and a magnet that can operate it is attached to the magnetic body with glass in between, and the ladder cord is connected in the head box so that it can be wound and unwound A supporting member, a rotating shaft connected to the supporting member so as to be integrally rotatable, and a supporting member driving device that can rotationally drive the rotating shaft are arranged, The holding member driving device includes a rotating drum rotatable integrally with the rotating shaft, a drum receiver rotatably supporting the rotating drum, and a fixed drum non-rotatably mounted on the drum receiver so as to be in series with the rotating drum. And a spring provided on the outer periphery of the rotating drum and the fixed drum, and for always urging the rotating drum in the ladder cord winding direction on the side having the magnetic material.

[0005]

When the magnet is moved downward, the magnetic material also moves downward integrally therewith, so that the ladder cord on the magnetic material mounting side also descends, and the support member rotates accordingly. As a result, the support member takes up one ladder cord and unwinds the other ladder cord, so that the slats are inclined. At this time, the rotation of the support member is transmitted to the rotating drum via the rotating shaft. Next, when the magnet is moved upward, the magnetic body also moves upward together with the magnet, so that the ladder cord between the support member and the magnetic body is loosened. The rotary drum is constantly applied with a force for rotating the support member in the ladder cord winding direction by a spring, and thus rotates in the direction opposite to the direction when the magnetic body is lowered by the slack of the ladder cord.
Thereby, the support member rotates integrally with the rotating drum via the rotating shaft. As the support member rotates, the other ladder code is wound and one ladder code is unwound. Thereby, the slats are inclined in the direction opposite to the direction when the magnetic body is lowered. Therefore, when the magnetic material is raised, the support member is reliably rotated by the amount of the magnetic material raised by the rotating drum, so that the rotation of the slat is improved.

Is moved up and down, so that the magnet 42 and the magnetic body 38 adsorbed by the magnet 42 move up and down, so that the magnet 42 is wound and unwound on the support member 28. Further, as will be described later, the indoor ladder cord 24 is always pulled by the spring 36 of the rotating drum 32 in a direction in which it is wound on the support member 28, and therefore moves without loosening. The outdoor ladder cord 25 is unwound and wound around the support member 28 in reverse to the indoor ladder cord 24.
Note that the attraction between the magnet 42 and the magnetic body 38 is set to be larger than the rotational torque stored in the spring 36.

FIG. 3 is a diagram (plan view) showing the support member driving device 31 in detail, and FIG. 4 is a diagram (front view) of the support member driving device 31 of FIG. 3 viewed from the same direction as FIG. Show. The drum receiver 34 has a substantially U-shaped cross section, and rotatably supports the rotating shaft 30 penetrating the opposing walls 44 and 46. The rotating drum 32 is arranged inside the drum receiver 34 adjacent to the wall portion 44.
The rotary drum 32 is integrally rotatably supported by a rotary shaft 30 which penetrates the inside of the rotary drum coaxially. Wall 46
A fixed drum 48 is non-rotatably mounted on the side facing the wall 44. The rotating shaft 30 is rotatably penetrated through the inside of the fixed drum 48. A spring 36 is provided between the rotating drum 32 and the fixed drum 48. Both ends 36a and 36b of the spring 36 are bent at right angles, respectively,
It is hooked on grooves 52 and 54 respectively formed on the four-side end and the end of the fixed drum 48 on the wall 46 side. Groove 5 of rotating drum 32 and fixed drum 48
The protrusions 56a are spaced 180 degrees apart from each other on the inner peripheral
And 56b, and 58a and 58b, respectively. One end of the spring 36 has the protrusion 56a and the protrusion 5
6b, the other end between the projections 58a and 58b,
Each of them is provided so as to be sandwiched therebetween, whereby the axial movement of the spring 36 is restricted.

Next, the operation of this embodiment will be described.
When the operation knob 44 is moved downward, the magnetic body 38 attracted to the magnet 42 also moves downward. Therefore, the indoor ladder cord 24 is unwound from the support member 28, and the outdoor ladder cord 25 is wound around the support member 28. Thereby, the slat 20 rotates counterclockwise in FIG. 2 and inclines so that its indoor end is located downward and its outdoor end is located upward. At this time, since the support member 28 rotates counterclockwise in FIG. 2, the rotary drum 32 also rotates integrally with the support member 28 via the rotary shaft 30. Next, when the operation knob 44 is moved upward from the above state, the magnetic body 38 attracted to the magnet 42 also moves upward. At this time, since the indoor ladder cord 24 tends to be loosened, there is no longer any force pulling the rotary drum 32 counterclockwise in FIG. 2, and the rotary drum 32 rotates clockwise in FIG. Thereby, the support member 28 rotates integrally with the rotary drum 32 in the clockwise direction in FIG. Thus, the outdoor ladder cord 25 is unwound from the support member 28, and the indoor ladder cord 24 is unwound from the support member 28.
It is wound up. For this reason, the slat 20 rotates clockwise in FIG. 2 and inclines so that its outdoor end is located downward and its indoor end is located upward. In the above-described embodiment, the lower end of the ladder cord is connected to the bottom rail. The present invention is also applicable to a case where the ladder codes are slidably connected.

[0010]

According to the present invention, since the rotating drum is constantly biased by the spring in the ladder cord winding direction on the side having the magnetic material, the supporting member is supported by the rotating drum when the operating device is raised. The rotation can be ensured by the amount of the rise of the cord. Thereby, the rotation of the slat is improved, and the shielding property when the slat is fully closed is excellent.
