Description

[Detailed description of the invention] [Industrial field of application] The present invention includes a blind and an operating body for the blind interposed between a pair of glass plates facing each other at a predetermined interval, and the operating body By providing operating tools facing each other with one glass plate in between, and attaching magnets to the operating body and the operating tool, respectively, which interlock the two by magnetic force, it is possible to eliminate the need to drill holes in the glass plate or the sash frame. This invention relates to double-glazed glass fittings with blinds that can seal between a pair of glass plates and prevent condensation and staining on the inner surface of the glass plates.

[Conventional technology]

As this type of double-glazed glass fittings with blinds,
Conventionally, a slat angle changing operating member, which is an example of an operating body, and a handle, which is an operating tool, are configured to be rotatable around an axis along a direction perpendicular to a pair of gas plates, and a magnet on the operating body side, The operating tool side magnets are configured such that their N poles and S poles are alternately located along the direction of rotation, so that when the operating tool side magnets are rotated by operating the handle, the operating tool side magnets can be operated. A device in which the angle of the slat can be changed by rotating the body side magnet has been considered.

[Problem that the invention attempts to solve]

However, in the conventional configuration described above, the slats of the blind generally rotate around an axis parallel to the glass plate to change its angle; A mechanism for converting the direction of rotation to a substantially right angle is required between the angle changing operating member and the slat, and the interlocking structure between the operating body and the blind tends to become complicated.

In view of the above-mentioned circumstances, an object of the present invention is to enable an operating body and a blind to be linked with each other with a simple configuration.

[Means for solving problems]

The characteristic configuration of the double-glazed window fittings with blinds according to the present invention is that the operating body and the operating tool are parallel to a pair of glass plates facing each other with a predetermined interval apart, and
The slats of the blind interposed between the pair of glass plates are configured to be rotatable around an axis along the longitudinal direction, and the operating body-side magnet and the operating tool-side magnet are configured such that their N and S poles, respectively, are rotatable. The reason is that they are installed so that they are positioned alternately along the rotation direction.

[Effect]

That is, for example, if a prismatic magnet that is divided into N and S poles in cross-sectional view is used as the operating body side magnet and the operating tool side magnet, as shown in FIG. In conjunction with the rotation of the operating tool side magnet 5A shown on the right side of the figure as the tool rotates, the operating tool side magnet 4A provided across the glass plate 2A rotates in the opposite direction.

That is, a rotational force is generated against the operating body side magnet 4A by the resultant force of the attracting force between the magnetic poles of the operating tool side magnet 5A and the operating body side magnet 4A and the repulsive force between the magnetic poles of the same magnetic property, and this rotational force causes The operation body side magnet 4A is rotated in the opposite direction in conjunction with the rotation of the operation tool side magnet 5A, and accordingly, the operation body is rotated in the same direction.

Since the operating body rotates around an axis parallel to the glass plate in conjunction with the rotation of the operating tool, for example, the slat of a blind inserted between a pair of glass plates can be When changing the angle by rotating the glass plate around an axis parallel to the glass plate, the direction of rotation of the operating body and the direction of rotation of the slat are the same, so the distance between the operating body and the blind is The interlocking mechanism can omit a mechanism that converts the direction of rotation to a substantially right angle, which is conventionally required.

[Effects of the invention] As a result, as the interlocking mechanism is simplified, the number of parts that make up the interlocking mechanism can be reduced, the operating body and the blind can be smoothly interlocked, and troubles in this interlocking mechanism can be avoided. It is now possible to reduce the amount of glass generated and provide highly reliable double-glazed glass fittings with blinds at an advantageous cost.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 2, a pair of glass plates 2 are placed at a predetermined interval on a sash frame 1 assembled into a rectangular shape.
Insert A and 2B into the pair of glass plates 2
A double-glazed glass fitting with a blind is constructed between A and 2B with a blind 3 interposed therebetween.

This blind 3 consists of a pair of glass plates 2A, 2
A bottom rail 3A substantially parallel to B, and a plurality of slats 3B substantially parallel to this bottom rail 3A.
It is composed of etc. The bottom rail 3A and the slat 3B are both rotatably attached to the glass plates 2A, 2B about axes parallel to each other.

And those bottom rail 3A and slat 3
A slat angle changing operation device SA for rotating the slat angle B and changing the angle thereof (hereinafter collectively referred to as slat angle changing) is provided on the upper part of the glass fitting.

As shown in FIGS. 1 and 2, this slat angle changing operation device SA includes an operating body 4 interposed between a pair of glass plates 2A and 2B together with a blind 3, and one side of the operating body 4. It is composed of an operating tool 5 disposed opposite to each other with a glass plate 2A in between.

The operating body 4 and the operating tool 5 are rotatable about respective axes X ₁ and X ₂ parallel to the pair of glass plates 2A and 2B and along the longitudinal direction of the slats 3B of the blind 3, respectively. attached.

The operating body 4 is provided at one end of the glass fitting. A pair of pulleys 7 provided at two locations in the width direction of the glass fittings are linked to this operating body 4 via a linking rod 6. A ladder cord 8 is wound around the pair of pulleys 7.
Both ends thereof are fixed to both side edges of each slat 3B and bottom rail 3A, respectively.

On the other hand, a winding drum 9 is connected to the operating tool 5, and an operating cord 10 is wound around the winding drum 9. The operating tool 5, winding drum 9, etc. are housed in a case 11, and both ends of the operating cord 10 are suspended downward from the case 11.

The operating body 4 and the operating tool 5 are each equipped with a prismatic operating body-side magnet 4A and an operating tool-side magnet 5A for interlocking the two using magnets.
As shown in FIGS. 3A to 3G, both of the magnets 4A and 5A are magnetized so as to be divided into two parts, an N pole and an S pole, in a cross-sectional view.

When the operating tool 5 is rotated by pulling down either end of the operating cord 10, the operating tool side magnet 5A
In conjunction with the rotation, the operating body side magnet 4A rotates,
The structure is such that the angle of the slat 3B can be changed.

To explain this interlocking state further, from the state shown in FIG. 3A, the operating tool side magnet 5A is
When forcibly rotated counterclockwise around the second axis _X2 parallel to A and 2B, the repulsive force between the S pole of the operating tool side magnet 5A and the S pole of the operating tool side magnet 4A causes the As shown in Figure 3B, the operating body side magnet 4A
is the first axis X ₁ parallel to the glass plates 2A and 2B
Start rotating clockwise around the

On the other hand, since the S pole of the operating tool side magnet 5A and the N pole of the operating tool side magnet 4A attract each other, the operating tool side magnet 4A
continues to rotate in a direction that brings these two poles closer together, that is, in a clockwise direction, as shown in FIG. 3C.

Furthermore, as shown in FIG. 3D, even after the S pole of the operating tool side magnet 5A and the N pole of the operating tool side magnet 4A are opposed and stabilized, if the operating tool side magnet 5A is rotated counterclockwise. , as shown in FIG.
rotates clockwise.

Then, the N pole of the operating tool side magnet 5A is connected to the glass plate 2.
When it is rotated to face A and 2B, as shown in FIG. Due to the force of attraction between the N pole of the magnet 5A and the S pole of the operation body side magnet 4A, the operation body side magnet 4A further rotates clockwise, and becomes the state shown in FIG.

Thereafter, by rotating the operating tool side magnet 5A counterclockwise, the operating tool side magnet 4A continues to rotate clockwise in the same manner as described above.

That is, as described above, the rotational force on the operating body side magnet 4A is generated by the resultant force of the attraction between the magnetic poles of the operating tool side magnet 5A and the operating body side magnet 4A and the repulsive force between the magnetic poles of the same magnetic property. Due to this rotational force, the operation body side magnet 4A is rotated in the opposite direction in conjunction with the rotation of the operation tool side magnet 5A.

As a result, the interlocking mechanism between the operating body 4 and the slats 3B of the blind 3 is simple because their rotation directions are the same, reducing the number of parts, smoothing the interlocking, and reducing the occurrence of trouble. can be measured.

[Another example]

In the embodiment, the configuration for changing the angle of the slats 3B of the blind 3 has been described, but the interlocking configuration using magnetic force between the operating body 4 and the operating tool 5 according to the present invention allows the blind 3 to be moved to the slats 3B.
It may also be applied to a configuration for expanding and contracting in the direction in which these are arranged side by side.

In this case, the operating body for extending and retracting the blind is replaced with the operating body 4 for changing the slat angle described in the previous embodiment.
It may be used for both purposes, or it may be provided separately.

In addition, the operating body side magnet 4A and the operating tool side magnet 5A
may be a permanent magnet or an electromagnet,
The type does not matter. In addition, the configuration of any magnet can be changed as appropriate as long as the magnetic poles are arranged so that north poles and south poles are alternately located along the direction of rotation. Next, several examples will be explained with reference to the drawings.

The one shown in Fig. 4A has a hexagonal cross-sectional shape, and the portions corresponding to each side of this hexagon are
It is magnetized alternately to N and S poles. Also, the fourth
The one shown in FIG. 7 has a hexagonal star shape in cross-sectional view, and portions corresponding to the vertices of this star shape are alternately magnetized to N and S poles. Furthermore, the fourth
The one shown in Figure C has a circular cross-sectional shape, and this circle is divided into four parts in the circumferential direction.
The pole and S pole are magnetized. In addition, although not shown, the interlocking can be smoothed by increasing the number of divided magnetizations.

In addition, although the configuration in which the operating body side magnet 4A and the operating tool side magnet 5A are divided into the same number of magnetized states in the previous embodiment has been described, they do not necessarily have to be the same.

The blind 3 used in the double-glazed window fittings with blinds of the present invention may be of a horizontal type or a vertical type. Further, the material of the slat may be metal or plastic. Furthermore, the glass fittings may be windows or doors.
