Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-glazing glass with a built-in blind, and more particularly to a slat rotating mechanism provided for adjusting a light blocking state by a slat built in the double-glazing.

[0002]

2. Description of the Related Art A double glazing with a built-in blind is a double glazing consisting of two substantially same-shaped indoor side glass plates and outdoor side glazings, and these double glazings are designed so as to close the gap between the double glazings from the outside air. It has a frame structure composed of a frame body (generally, the upper and lower frames constituting the frame body are called "spacers") assembled on the four outer peripheral sides of the laminated glass, and a vertical flat gap space formed by these. In the (internal space), a blind as an assembly in which a large number of slats are supported by ladder-shaped ladder cords at predetermined vertical intervals is housed, and these slats are rotated and tilted for adjusting the light shielding state. It is known as a structure in which a ladder cord rotating mechanism is provided so that it can be operated from outside the double glazing.

The ladder code rotating mechanism incorporated in the above-mentioned double-glazing with built-in blind is generally equipped with a rotary shaft for suspending the ladder code and rotatable about its axis above the inner space inside the double-glazing. However, an operating mechanism for artificially rotating the rotating shaft from the outside is provided. For example, the operating mechanism is attached to the outer surface of the glass at the same height as the rotating shaft. 2-4616
No. 0), a dial type rotary operation shaft that penetrates the wall surface of the vertical spacer on one side inward and outward is provided, and the shaft part in the vertical spacer of the dial type rotary operation shaft and the rotary shaft for the ladder cord are in a twisted relationship with each other. A type in which the rotation transmission string is hung between the shafts and the rotation when the dial type rotary operation shaft is operated from the outside is transmitted to the rotation shaft for the ladder cord via the transmission string (No. 2-13677, No. 5-677
No. 94), a magnet for driving is attached to the vertical cord of the ladder cord that constitutes the blind housed in the inner space between the double glazings so that it can be moved vertically by contacting the inner surface of the glass. Of a type in which an operating magnet for moving the operating magnet in the vertical direction is slidably attached to the outer surface of the glass (Jun. 1-35996, Jun. 62-91).
No. 895) and the like are already known.

[0004]

However, in the ladder cord rotating mechanism proposed in, for example, Japanese Patent Laid-Open No. 2-46160, the operating portion is arranged at the same height as the rotating shaft from the outside of the rotating operating mechanism. However, in the case of a tall product, the operating position is too high and it is difficult to reach, which causes operational defects.
Therefore, there is a problem in that the size (height) of the blind-containing double-glazing to which the mechanism can be applied is restricted.

Further, in the mechanism proposed in Japanese Utility Model Publication No. 2-13677, since the dial type rotary operation shaft penetrates the wall surface of the vertical spacer in and out, the internal space for housing the blind is sealed from the outside air. However, there is a problem that it is not easy to maintain the sealed state for a long period of time without adjustment and without replacement of parts, because the structure is such that the rotary contact portion seals. It is required to seal the above internal space from the outside air because dust cannot be easily cleaned because the structure cannot be cleaned easily.
This is because it is desirable that no dust be intruded, and that it is desirable to enclose and maintain dry air in order to avoid condensation inside due to the temperature difference between the inside and outside of the building.

Furthermore, the magnets are attached to the vertical cords of the ladder cords, as described above in Japanese Utility Model Publication No. 1-35996 and Japanese Utility Model Publication No. 62-918.
In the mechanism proposed by No. 95, the pair of front and rear vertical cords of the rudder cord originally have the movement to widen or narrow the gap according to the tilted state of the slats. As a result, the movement of the vertical string is restricted, and as a result, there is a problem that the posture of the slat at the time of rotation and tilting, particularly the posture at the time of maximum tilting becomes insufficient, and the light blocking state becomes inappropriate. This is the gap between the glass is 10
A blind built into a multi-layer glass of about mm has a fatal drawback because there is little overlap between the upper and lower slats.

The present invention has been made in order to provide a novel ladder cord rotating mechanism which solves the drawbacks of the conventional type ladder cord rotating mechanism incorporated in the above-mentioned blind-embedded double glazing. One of its purposes is that it can be easily operated from the outer surface of the glass, which makes it possible to reduce the size of the frame (spacer) without the need for accommodating a rotating mechanism or an operating mechanism in the frame at the periphery of the glass, and thus the opening. It is an object of the present invention to provide a double-glazing unit with a built-in blind that can increase the rate (rate occupied by the glass surface).

Another object of the present invention is a structure capable of reliably transmitting the movement of a rotary operation mechanism that is artificially operated from the outside to the rotary shaft and completely sealing the internal space from the outside air. We are providing a double-glazing with built-in blinds.

Still another object of the present invention is to simplify the rotary operation mechanism from the outside as much as possible, and to install it in a position easily reachable by the operator, so that the operation is easy and the design is simple. Is also in the position of providing excellent double glazing with built-in blinds.

Still another object of the present invention is to provide a double-glazing unit with a built-in blind, which is easy to assemble in a factory or the like and easy to work in an installation site.

Another object of the present invention is to easily adjust a cord for transmitting a rotational force used in a rotary operation mechanism from the outside when the cord is stretched and slackened due to aging. It is to provide a double-paned glass with a built-in blind that can be tensioned again during work.

[0012]

The characteristics of the double-glazing glass with a built-in blind according to the present invention for achieving the above-mentioned object are the features described in each of the claims.

The feature of the invention described in claim 1 of the present invention resides in that a frame is assembled to the peripheral edges of two sheets of glass facing each other with a gap provided therebetween, and the gap space is hermetically sealed from the outside air, and this sealing is performed. In the blind space double glazing containing the blind that hangs the slats rotatably through the ladder cord by the rotating shaft in the stopped clearance space, the blind glass has a magnet and is artificially touching the outer surface of the glass. A dial that is rotated and a driven pulley that has a magnet and that rotates coaxially while being in contact with the inner surface of the glass by following the rotation of the magnet by the interaction of these magnets are provided from the upper horizontal spacer of the frame body. Assembling one piece of the glass at a lower position positioned downwardly so as to hold it, and to accommodate the rotary shaft of the blind in the upper horizontal spacer, Certain serial driven pulley where forming a structure that was ligated code for rotation transmission.

The double-glazing glass with a built-in blind of the present invention is a glass window structure in which a glass window structure formed by using a quadrilateral frame as a skeleton is incorporated into a window opening of a building to form a glass window. The glass has a substantially fixed structure that is not removable. The "frame body" is formed by connecting upper and lower, left and right spacers, which are usually made of aluminum, with corner blocks at four corners. These spacers are U-shaped, inverted U-shaped with an opening in the internal space if necessary.
For example, the upper horizontal spacer (hereinafter, simply referred to as “upper spacer”) is provided in the shape of a letter U and has an inverted U shape that is opened downward so as to accommodate the rotary shaft for suspending the ladder cord therein.
It is provided in a letter shape. Although transparent glass is used, glass having a structure in which the built-in blind is effective in adjusting the light-shielding state, such as frosted glass, is not excluded.

The "airtightly sealing from the outside air" in the gap space (internal space) prevents contamination due to the circulation of the inside and outside air, and can enclose and retain dry air so that dew condensation does not occur inside. Although it is sufficient, a means for absorbing the volume change of the enclosed air due to the temperature change, for example, a diaphragm type volume change absorbing mechanism may be provided in the spacer, if necessary.

The above-mentioned "dial" may have any structure as long as it has a magnet and has a structure suitable for being artificially rotated while being in contact with the outer surface of the glass. A flat circular plate is suitable. Specifically, a member fixed to a glass at a predetermined position with an adhesive or the like, for example, a perforated dial having a circular inner peripheral edge for engaging the outer circumference of the dial and rotatably holding the dial. A circular dial or the like configured in combination with a holder (fixing member) can be exemplified. By using such a perforated dial holder,
Positioning and assembly work of the dial is greatly facilitated,
Moreover, the position of the dial after installation is constant, and the certainty of operation can be secured. It is preferable that the dial and the driven pulley are provided with a magnetic body (for example, an iron plate) for forming a magnetic circuit together with the magnet, and the structure excluding these magnet and magnetic body is usually formed of plastic. Further, the surfaces of these dials and driven pulleys that come into contact with the glass may be coated with a suitable plastic film or plastic sheet by a bonding means such as welding in order to prevent rust of the magnetic material and reduce sliding resistance. preferable.

With respect to the dial assembling structure, it is possible to provide an assembling position relocating means for changing and adjusting the dial assembling position in the vertical direction. That is, it is usually difficult to prevent the connecting cord that transmits the rotation of the driven pulley described above from rotating to the rotating shaft of the blind due to deterioration over time.Therefore, if such elongation occurs, the rotation of the dial assembly will not be hindered. It is possible to provide repositioning means for moving the attachment position to adjust the tensioned state. Specific examples of such means include a configuration in which a dial is vertically adjustable in position with respect to a dial holder fixed to a glass plate with an adhesive. Also, in the case of a configuration in which a short one is used as part of the slats in order to avoid overlapping with the rotary operation mechanism, the area where the slats are not extended is covered with the opaque dial holder to protect the light. It is preferable to give.

In the present invention, the dial preferably has a plurality of magnets arranged in the circumferential direction so that the N poles and the S poles alternately face the glass surface. Corresponding to this, the driven pulley is the N of the dial.
It is preferable to have the same number so that the magnets of the opposite poles are opposed to the poles and the S poles, in order to exert the action of the magnets that exert a magnetic force in a non-contact manner via the glass as effectively as possible. A magnet having a strong magnetic action, for example, a rare earth element magnet such as a samarium-cobalt magnet or a neodymium magnet is preferably used.

[0019]

According to the present invention, the operating dial can be arranged within the reach of the operator without being affected by the size of the double-glazing with built-in blind, and the tilting posture of the slat can be rotated by rotating the dial. Can be adjusted. Further, stains and dew condensation on the blind can be prevented by reliably sealing the internal space from the outside air.

In these figures, reference numeral 1 is a rectangular interior side glass, 2 is an exterior glass of the same shape, and a rectangular frame-shaped frame body 3 is assembled between these four side edge parts to the inside. It forms an internal space 9. The frame 3 is composed of an upper spacer 301, a lower spacer 302, vertical spacers 303 and 304 formed of an aluminum member, and corner blocks 305 to 308 connecting these at the corners of the frame.

The upper spacer 301 has an inverted U-shape with a downward opening, in which the rotary shaft 5 is extended along its longitudinal direction, and a ladder cord is provided at a pair of left and right positions in the middle thereof. The hanging drums 5 and 5 are axially mounted so as to rotate integrally with the rotary shaft 4. A rotary operation mechanism 1 to be described later is attached to one end (left side in FIG. 1) of the rotary shaft 4.
A rotation transmission drum 6 for transmitting the rotation from 0 is similarly mounted on the shaft.

The ladder cords 7, 7 whose upper ends are connected to the above-mentioned ladder cord suspension drums 5, 5 are suspended below the inner space so that a large number of slats 8, 8 ... It is supported at intervals. In this example, each of these slats is provided with a through-hole at its end (the right end in FIG. 1) so that a fall-prevention wire 9 laid vertically can be inserted. The wire 9 serves to prevent the slats from falling and to position the slats in the longitudinal direction, and both ends thereof are fixed to the upper spacer 301 and the lower spacer 302.

Further, a part of the slats of this embodiment (designated by reference numeral 801 in FIG. 1) is provided in a short length so as not to overlap the structure with a rotary operation mechanism 10 which will be described later, as shown in FIG. There is.

Next, the rotation operation mechanism 10 and the rotation transmission mechanism 11 for rotating the rotary shaft 4 will be described.

The rotary operation mechanism 10 of this example will be clearly described with reference to FIG. 2 showing a state when the slats are opened and FIG. 3 showing a longitudinal section thereof. That is, the rotary operation mechanism 10 adheres and fixes a plate-shaped dial holder 101 having a circular opening to the glass 1 with an adhesive, and rotatably supports a stepped holding portion 102 provided on the inner edge of the opening of the dial holder 101. A circular dial 103 is assembled to form a rotating part that can be manually operated, and a driven rotating part is arranged to face the inner space 9 while sandwiching the glass 1.

In the present example, the circular dial 103 is a plastic plate magnet holder 103.
1 has six magnets 104 and 105 along its circumferential direction (the magnet whose N pole faces the glass surface is shown by 104, and the magnet whose S pole faces the glass surface is shown by 105). A circular iron plate 10 for forming a magnetic circuit on the surfaces of the magnets 104 and 105 on the side opposite to the glass surface.
6 is provided in the structure. On the surface of the dial 103 of this example that comes into contact with the glass, a gas impermeable film or plate (not shown) having a low coefficient of friction is welded to prevent corrosion of the built-in iron plate and reduce sliding resistance. It is covered by a coupling means such as. Also this dial 10
It goes without saying that the outer surface of 3 is provided, for example, in a ribbed shape or the like suitable for the rotation operation of the operator.

The driven pulley 108, which constitutes the driven rotating portion disposed in the internal space, is composed of the magnet 104 of the dial 103,
105 has six magnets installed so that the poles opposite to 105 face each other, and also has a plastic plate-shaped magnet holder 1032 and an iron plate 107 having the same configuration, and the rear side opposite to the glass 1 in the axial direction. It has a structure in which a pulley shaft portion 109 is provided at the end portion.

Since the artificial operation rotating part and the driven rotating part have magnets which exert an attractive force on each other, the driven pulley 108 is driven to rotate by rotating the dial 103. .

This rotation is caused by the driven pulley 108,
Rotation transmission cord 11 installed along the outdoor glass 2
It is transmitted to the rotation transmitting drum 6 rotatably attached to the rotating shaft 4 via the rotation transmitting mechanism 11 composed of 0 and 0. The rotation transmission cord 110 in this example has two cord ends provided for clockwise rotation and counterclockwise rotation, respectively.
Although the rotation transmission drum 6 and the fastener clips 601, 601, 1081, 1081 of the driven pulley 108 are connected to each other, a loop-shaped cord may be wound around these two shafts.

The movement of each part associated with the operation of the double-glazing with a built-in blind having the above construction will be described with reference to the drawings. In the state where the slats shown in FIGS. 1 and 2 are opened, the slats 8, 8, ... ... has a horizontal posture,
Each part is in the state shown in FIGS. 3 is a vertical sectional view of FIG. 2, FIG. 4 is a vertical sectional view taken along the line AA of FIG. 3, and FIG.
Shows a vertical sectional view taken along the line BB of FIG.

Next, when the dial 10 is rotated clockwise in FIG. 1, the rotation transmission cord 110 causes the rotation transmission drum 6 and the rotation shaft 4 pivotally attached to the rotation transmission cord 110 to rotate through the rotation of the driven pulley 108. 3 is rotated counterclockwise and the slats 8, 8 ... Are tilted to the slats closed state shown in FIGS. 6 to 9 to secure a predetermined light shielding state. Further, in this example, the range where the short slats shown by reference numeral 1 are not extended is covered by the opaque dial holder 101, so that the light shielding state is not hindered.

FIG. 6 is shown in FIG. 2, FIG. 7 is shown in FIG. 3, and FIG.
4 and 9 show the slat closed state at a position corresponding to FIG. 4 and FIG. 5, respectively.

As described above, according to this embodiment, the blind slat can be opened and closed easily and reliably by manually rotating the dial 103 held by the dial holder 101. Since the mechanism for transmitting the rotation from the outside is the driven pulley 108 and the rotation transmitting cord 110 housed in the internal space, there is no through-hole for circulating air inside and outside, so that the internal space is sealed from the outside air. The stop can be reliably secured and maintained over a long period of time. Further, because of the above-mentioned configuration, since only the rotary operation mechanism such as the dial and the rotation transmission cord are visible from the indoor side, it is possible to make the double-glazing with a built-in blind excellent in design.

Embodiment 2 In this embodiment shown in FIGS. 10 and 11, after the blind built-in double glazing is assembled to a predetermined window, the rotation transmission cord 110 is stretched due to aging or the like. , An example in which re-localization means for changing the installation position of the dial 103 is provided, and other configurations are the same as those in the first embodiment, and therefore, illustration and description of the same configuration will be omitted.

The feature of this embodiment is that, instead of the dial holder 101 of the first embodiment, it has a rectangular four-sided frame shape and has outward vertical grooves 22, 22 on the left and right frame sides 21, 21, respectively. Holder support 2 formed to have ratchet teeth 24, 24 on the surfaces of the upper and lower frame sides 23, 23
0 is fixed to a predetermined position of the indoor glass 1 with an adhesive, and a dial holder 3 having a circular opening 31 having a stepped holding portion 32 for holding the dial 103 at its inner edge is formed.
0 is supported by the holder support 20.

That is, the dial holder 30 is formed with a four-sided frame-shaped recess so as to cover the holder support 20, and the left and right vertical recesses 33, 33 are formed with outward vertical grooves on the left and right frame sides of the holder support. Flanges 34 and 34 that are fitted slidably in the up and down direction with 22, 22 and upper and lower recesses 35 that fit with the upper and lower frame sides 23 and 23 of the holder support,
35 is a ratchet tooth 24, 24 of the holder support.
Ratchet teeth 36, 36 that mesh with the upper and lower recesses 35, 35 of the dial holder 30 and the upper and lower frame sides 23, 23 of the holder support 20 are allowed to move relative to each other in the vertical direction as shown in FIG. There is a play gap that is offset upward.

By doing so, the dial holder 30 is surely movable in the vertical direction by fitting the flanges of the left and right vertical recesses 33, 33 into the vertical grooves 22, 22 of the holder support 20. Further, the upper and lower frame sides 23, 23 of the holder support and the upper and lower recesses 35, 35 of the dial holder 30 are fitted with a clearance in the up and down direction, and the ratchet teeth 24, 36 are meshed with each other to keep the assembly position normally However, if necessary, the dial holder 30 can be strongly pushed downward to shift the meshing engagement of the ratchet teeth 24 and 36 and reposition the position downward.

Therefore, when the rotation transmission cord 110 is elongated due to aging, the dial holder 3 is
The tension of the chord can be restored by performing a reorientation of 0 downward.
