[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light-shielding mechanism with a built-in double-layer glass window provided with a light-shielding plate (blind) that can be opened and closed in a double-layered glass.
[0002]
[Prior art]
So-called double glazing, in which the window glass is double-layered inside and outside, has been conventionally proposed for the purpose of insulating external light in summer or insulating noise from the outdoors. In recent years, by incorporating a blind mechanism that can be opened and closed in the space of double glazing, both heat insulation and heat shielding effects can be achieved in the summer, and the angle of the blades (slats) in the winter can be adjusted by adjusting the angle of the blades. There has been proposed a light-shielding mechanism with a built-in double-layer glass window, which can adopt a light-shielding mechanism.
[0003]
[Problems to be solved by the invention]
By the way, since the above-mentioned light shielding mechanism with a built-in double-layer glass window has a structure in which the slat is opened and closed by manually operating a string, the operation for adjusting the slat to a predetermined angle is troublesome. In addition, since the slat is positioned by its own weight, there is a limit to the mounting angle of the window frame, and the slat itself needs to be bent. Further, there is a problem that the slats are arranged only in the horizontal direction and cannot be arranged vertically or curvedly.
[0004]
The present invention has been made in order to solve the above-described problems.The slats can be opened and closed by electric power, and the opening and closing angle of the slats can be easily adjusted. It is an object of the present invention to obtain a light shielding mechanism with a built-in double-layer glass window that can be arranged vertically.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the double-glazed window built-in light-shielding mechanism according to the present invention has a double-layer glass arranged to be spaced apart from a panel frame, and a large number of the glass are arranged in parallel in the double-layer glass. A light-shielding plate, supporting both ends of each light-shielding plate so that tension is applied to each light-shielding plate, and meshes with a rotating member having a driven gear at each outer end so as to interlock with a driven gear of the rotating member one side at a time. A pair of rotation transmitting members, a driving motor having a driving gear meshing with one end of one of the rotation transmitting members, and an interlocking shaft that allows both other ends of the rotation transmitting members to interlock with each other; The light shielding plate can be opened and closed in an electric manner by forward and reverse rotation operations.
[0006]
According to the above-described light shielding mechanism with a built-in multilayer glass window, when the drive motor is driven, one of the rotation transmitting members meshing with the drive gear slides. This rotation transmission member can simultaneously slide the other rotation transmission member via the interlocking shaft, thereby rotating the rotation member via the driven gear meshing with both rotation transmission members, and opening and closing the light shielding plate. Can work. The angle adjustment and the closing operation of the light shielding plate can be performed by the on / off operation of the drive motor together with the forward / reverse rotation operation of the drive motor.
[0007]

[0009]
In FIG. 1, it is a panel frame of a light shielding mechanism that surrounds four circumferences by an upper panel frame 1a, a right panel frame 1b, a lower panel frame 1c, and a left panel frame 1d. As shown in FIG. 2, a glass window 2a, 2b is attached and fixed to the front and back surfaces of the panel frame 1 by bonding or the like to form a multi-layer glass window. Reference numeral 3 denotes a window opening of the multi-layer glass window. Department. Incidentally, the internal width space of both glass windows 2a, 2b is, for example, 15 mm.
[0010]
A large number of slats 4 are horizontally arranged in the window opening 3 in the space between the glass windows 2a and 2b. The slat 4 is formed of a belt-like stainless steel plate having a thickness of, for example, about 20 μm. FIG. 4 shows a detailed enlarged view of the support structure at one end side (the right end side in FIG. 1) of the slat 4. Reference numeral 5 denotes a rotary shaft that supports one end of the slat 4. The rotary shaft 5 has a flange 6 at an end thereof, and is attached to holding pieces 5 a and 5 b provided at an outer end of the flange 6. The ends of the slats 4 are clamped and fixed by caulking pins 5c.
[0011]
The above-described rotary shaft 5 is rotatably supported by a bearing tube 8 fixed to a support plate 7 of the right panel frame 1b. A pinion gear 10 is inserted into the rotating shaft 5 protruding from the bearing cylinder 8 via a coil spring 9 inserted into contact with the bearing cylinder 8, and the pinion gear 10 is a distal end of the rotating shaft 5. A stopper ring 12 made of rubber or the like which is non-rotatably inserted into a tip shaft 11 having a split groove formed in the above-mentioned manner prevents slipping out. A rotation restricting piece 13 is provided on the back surface side of the flange 6 of the rotary shaft body 5. The rotation is restricted by abutting the shaft.
[0012]
On the other hand, the support structure on the other end side (the left end side in FIG. 1) of the slat 4 is different from the support structure on the one end side of the slat 4 in that a coil spring 9 is used and a spacer is provided between the bearing cylinder 8 and the pinion gear 10. 15 has the same structure except that it is interposed.
[0013]
The slat 4 attached by the support structure as described above has the coil spring 9 compressed. That is, tension is applied to the slat 4 by the spring force of the coil spring 9, and a slip torque is generated between the pinion gear 10 and the stop ring 12, so that the slat 4 has a clutch function.
[0014]
In FIG. 1, a drive motor 16 composed of a DC motor and capable of rotating forward and backward is mounted in a corner formed by the upper panel 1a and the right panel 1b. The drive motor 16 includes an output gear 17. The output gear 17 meshes with a first rack gear 18, and the first rack gear 18 meshes with each pinion gear 10 on one side of each slat 4.
[0015]
A driven gear 19 is disposed at a corner formed by the upper panel 1a and the left panel 1d. The driven gear 19 is meshed with the second rack gear 20, and the second rack gear 20 is connected to the other side of each slat 4 respectively. Of the pinion gear 10.
The first rack gear 18 and the second rack gear 20 are interlockable with each other by interlocking interlocking gears 21a and 21b provided at both ends of the interlocking shaft 21 at lower ends thereof. Here, the first rack gear 18 meshes with the output gear 17, the pinion gear 10 and the interlocking gear 21 a from one surface side (the front side in FIG. 1), and the second rack gear 20 cooperates with the driven gear 19, the pinion gear 10 and the interlocking gear. The first rack gear 18 and the second rack gear 20 mesh with each other from the other surface side (the rear surface side in FIG. 1) of the first rack gear 21b.
[0016]
A first limit switch 22 for driving the drive motor 16 in the forward direction when in the ON state is disposed on an upper end side of the first rack gear 18, and an ON state is provided on an upper end side of the second rack gear 20. A second limit switch 23 for driving the drive motor 16 in the reverse direction is provided.
[0017]
Reference numeral 24 denotes a battery in which two 1.5 V dry batteries serving as a power source of the drive motor 16 are connected in parallel, and reference numeral 25 denotes a control switch for switching the drive motor 16 between forward rotation, reverse rotation, and an off position. FIG. 5 shows a connection diagram of the drive motor 16, the first limit switch 22, the second limit switch 23, the control switch 25, and the battery 24.
[0018]
In FIG. 2, the double-glazed window 26 configured as described above is built in a window frame 27. Assembled. Incidentally, the indoor side is 28 and the outdoor side is 29.
[0019]
Next, the operation of the light-shielding mechanism with a built-in multilayer glass window according to the present invention configured as described above will be described.
[0020]
As shown in FIGS. 1 and 3, the drive motor 16 is driven in the forward direction (clockwise) as shown in FIG. 3 by operating the control switch 25 from the state in which the slats 4 are oriented horizontally and the blinds are opened. Then, the first rack gear 10 moves upward in the direction of arrow a via the output gear 17. On the other hand, the second rack gear 20 moves downward in the direction of arrow b when the interlocking gear 21a, the interlocking shaft 21 and the interlocking gear 21b are rotationally driven from the first rack gear 18.
[0021]
As a result, the pinion gears 10, 10 meshing with the first rack gear 18 and the second rack gear 20, respectively, are rotated clockwise by the upward movement of the first rack gear 18 and the downward movement of the second rack gear 20. Then, the slat 4 rotates clockwise. Here, the manner in which the rotation is transmitted to the slats 4 will be described with reference to FIG. 4 on the first rack gear 18 side. The rotation of the pinion gear 10 is controlled by slip torque generated by the action of the spring pressure of the coil spring 9. 12 is rotated. Then, the rotating shaft 5 is rotated by the retaining ring 12, and the slat 4 rotates clockwise, and as shown in FIG. 6, the slat 4 rises in a substantially vertical direction to be in a fully closed state. In the fully closed state of the slat 4, as shown in FIG. 4, the rotation restricting piece 13 of the rotary shaft 5 contacts the stopper 14 a of the bearing cylinder 8 to restrict the slat 4 from rotating further.
[0022]
At this time, the leading end of the first rack gear 18 that moves upward contacts the first limit switch 22 to turn off the first limit switch 22, whereas the second rack gear 20 moves downward. By doing so, the second limit switch 23 is separated from the second limit switch 23, the second limit switch 23 is turned on, and the drive motor 16 can be driven in the reverse direction (counterclockwise).
[0023]
That is, as shown in FIG. 6, when the slat 4 is operated from the fully closed state and the control switch 25 is operated to drive the drive motor 16 in the reverse direction, the first rack gear 18 moves down and the second rack gear 20 moves up. The slat 4 rotates counterclockwise and opens again, and then the slat 4 is rotated by approximately 180 ° from the fully closed state in FIG. 6 to a fully closed state in which it rises in a substantially vertical direction as shown in FIG. . In the fully closed state of the slat 4, as shown in FIG. 4, the rotation restricting piece 13 of the rotary shaft 5 contacts the stopper 14 b of the bearing cylinder 8 to restrict the slat 4 from rotating further.
[0024]
At this time, the tip of the second rack gear 20 that moves upward contacts the second limit switch 23 to turn off the second limit switch 23, whereas the first rack gear 18 moves downward. As a result, the first limit switch 22 is separated from the first limit switch 22, the first limit switch 22 is turned on, and the drive motor 16 can be driven in the normal rotation direction (clockwise) again.
[0025]
In addition, since each slat 4 is engaged with the first rack gear 18 and the second rack gear 20 in which the pinion gears 10 and 10 at both ends are arranged on the left and right, the slats 4 are aligned in the same phase and are in the fully closed position. However, for example, even if there is a slat that rotates with a delay in phase, a slip torque is generated by the clutch function of the pinion gear 10 by the coil spring 9, and the slat can be aligned to the fully closed position.
[0026]
In the above description, the operation in which the slat 4 is inverted by 180 ° from the fully closed state and becomes the fully closed state again has been described. However, by turning the control switch 25 to the neutral position during the rotation of the slat 4, the drive motor 16 It can be stopped, and the outdoor light can be freely dimmed by stopping the slats 4 at a predetermined angular position.
[0027]
Further, since the slats 4 can be changed from the fully closed state of the normal rotation to the fully closed state of 180 ° inversion, the atmosphere of the blind window can be changed by changing the color of the front and back surfaces of the slats 4.
[0028]
The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.
[0029]
Since the slat 4 is configured to be tensioned by a coil spring, the slat 4 does not necessarily have to be horizontally oriented as in this example, and the slat 4 may be oriented vertically or obliquely such as a skylight. It can be set freely without being restricted by the mounting position of the double-glazed window.
[0030]
In this embodiment, the case where the slats are opened and closed by the control switch 25 provided on the frame of the multilayer glass window has been described. However, the light receiving element is provided on the multilayer glass window, and the drive motor 16 is driven by remote control operation. You may make it control.
[0031]
In addition, as an application example of the light shielding mechanism with a built-in double glass window, it can be widely applied to a sliding window, a casement window, a FIX window, a service door, a skylight, and the like.
[0032]
Further, the light-shielding mechanism with a built-in double-glazed window according to the present invention can be directly built without modifying a commercially available sash window frame.
[0033]
【The invention's effect】
As described above, the light-shielding mechanism with a built-in multilayer glass window according to the present invention includes a plurality of light-shielding plates arranged in parallel in a double-layered glass arranged at intervals on a panel frame, and each light-shielding plate. A rotating member provided with a driven gear at each outer end, and a pair of rotation transmitting members that mesh with each other so as to interlock with the driven gear of the rotating member one side at a time. It is composed of a drive motor having a drive gear that meshes with one end of one of the rotation transmission members, and an interlocking shaft that enables the other end of the rotation transmission member to be interlocked. The plate can be opened and closed freely, and thus, there is an effect that outdoor light can be freely and electrically controlled.
[0034]
Also, since the light-shielding plate is configured to be tensioned, the posture of the light-shielding plate can be not only horizontal but also vertically or obliquely such as a skylight. It can be set freely without being restricted by the posture.
