Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a double-glazed window fitting in which a blind is provided between glass plates mounted on a sash frame in a facing manner with an appropriate interval between them.

[Conventional technology]

In this type of conventional double-glazed window fittings with blinds, the blind operating device includes an operating member for expanding and contracting the blind and an operating member for changing the angle of the slats of the blind between the glass plates. A blind extension/contraction operating tool and a slat angle changing operating tool are provided on the outside of the glass plate; and were constructed by interlocking and connecting them through glass plates by magnetic force (for example, Utility Model Application No. 59-33161).

However, when using the conventional means, since the operating tool and the operating member are interlocked and connected by magnetic force, there is no need to make holes in the glass plate or the sash frame, and the gap between the glass plates is sealed, preventing dew condensation on the inner surface of the glass plate. Although there is no contamination due to dust adhering to the inner surface, there are two operating tools, one for extending and retracting the blind and the other for changing the slat angle, so it is necessary to change the operating tool when operating the blind. However, it lacked operability, and the installation space for the operating tools was large, making it unsightly.

[Problems to be Solved by the Invention] The present invention has been developed in view of these conventional drawbacks, and its purpose is to improve the operability of the blind and improve its appearance.

[Means for solving problems]

The characteristic configuration of the double-glazed window fittings with blinds according to the present invention, which was taken to achieve the above object, is that the operating device for the blind includes a sliding member that is movable along the surface of the glass plate, and the glass plate. An operating body consisting of a rotary member rotatable around an axis perpendicular to the plane is disposed between the glass plates, and the slat angle of the blind is changed by sliding movement along the plane of the glass plate. The sliding member is linked to the blind, and the rotating member is linked to the blind so that the blind expands and contracts based on the rotation about the axis, and the rotation member is perpendicular to the glass plate. Rotatable around the axis, and
An operating tool that can be slid freely along the surface of the glass plate is provided, and the operating tool and the operating body are interlocked across the glass plate by magnetic force,
Its action and effect are as follows.

[Effect]

In other words, since the operating tool and the operating body are linked through the glass plate by magnetic force, if the operating tool is slid along the surface of the glass plate, it will be placed between the opposing glass plates as it moves. The slide member that has been moved slides along the surface of the glass plate in the same manner as the operating tool. Further, if the operating tool is rotated around an axis perpendicular to the surface of the glass plate, the rotating member rotates around the axis for the same reason.

the sliding member is linked to the blind so as to change the slat angle of the blind by sliding movement along the surface of the glass plate;
Since the rotating member is linked to the blind so as to expand and contract the blind based on the rotation around the axis, the slat angle of the blind can be changed by the sliding movement of the operating tool. , the blind can be expanded and contracted by rotation around the axis.

In this way, since one operating tool is used both as an operating tool for extending and retracting the blind and for changing the slat angle, only one operating tool is required.

[Effects of the invention] As a result, the blind expansion and contraction adjustment and the angle adjustment of the slats can be performed in succession without changing the operating tool, and the installation space for the operating tool is reduced and the appearance is improved. We are now able to offer layered glass fittings.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 3 and 4, two glass plates 2, 2' are fitted and fixed in a sash frame 1 facing each other with an appropriate distance between the inner and outer glass plates 2, 2'. A double-glazed window with a blind is constructed by equipping the window with a blind 3 that expands and contracts vertically.

The blind 3 contracts by pulling up the bottom rail 3A, and slides 3C by swinging the balance 3B provided at the upper part between the glass plates 2 and 2'.
The angle of the slat 3C is changed by moving the ladder cord 3D fixed to the slat 3D up and down.

The operating device for the blind 3 is shown in FIGS. 1 and 2.
As shown in the figure, the inner frame 4, which is attached to the sash frame 1 while being located between the inner and outer glass plates 2 and 2', is rotated around an axis a perpendicular to the inner glass plate 2. An operating body 5 is installed that expands and contracts the blind 3 and changes the angle of the slats 3C of the blind 3 by moving up and down along the surface of the inner glass plate 2, and is located on the outer surface side of the inner glass plate 2. An operating tool 7 is interlocked and connected to the operating body 5 through the inner glass plate 2 via magnetic force to the outer frame 6 attached to the sash frame 1 in the state of
is installed and configured.

The operating body 5 includes a slide member 5A for changing the slat angle, which is attached to the inner frame 4 via a roller 5a so as to be slidable up and down, and this slide member 5.
It is composed of a pulley-shaped rotary member 5B for extending and retracting the blind, which is rotatably connected to A through a bearing 5b. The means for interlocking the slide member 5 with the balance 3B such that the balance 3B swings by the vertical sliding movement of the slide member 5A, that is, the angle of the slat 3C changes, is a means for interlocking the slide member 5 with the balance 3B by a pulley 8 interlockingly connected to the balance 3B. One end of the operating cord 9 for rotating the pulley 8 forward and backward is fixed to the slide member 5A in a downward position, while
The other end of the operating cord 9 is changed to an upward position by a grooved roller 10 attached to the inner frame 4 and fixed to the slide member 5A.
By sliding the slide member 5A downward, one end of the operating cord 9 is pulled downward to rotate the pulley 8 in the forward direction, and by sliding the slide member 5A upward, the other end of the operating cord 9 is pulled upward and the pulley 8 is pulled downward. It is a means to reverse rotation. The means for interlocking the rotary member 5B with the blind 3 so that the blind 3 is raised and lowered by the forward and reverse rotation of the rotary member 5B is a raised and lowered means that is movably guided by a pulley 11 provided at the upper part between the glass plates 2 and 2'. One end of the cord 12 is fixed to the bottom rail 3A, the other end of the lifting cord 12 is fixed to the rotating member 5B, and then the lifting cord 12 is wound up by the forward rotation of the rotating member 5B and the bottom rail 3A is fixed. This is a means for rewinding the lifting cord 12 by pulling it up and reversing the rotation of the rotating member 5B, and lowering the bottom rail 3A by its weight.

The operating tool 7 includes a slide member 7A attached to the outer frame 6 so as to be slidable up and down, and a slide member 7A rotatably supported on the slide member 7A around an axis a' perpendicular to the inner glass plate 2. Operation handle 7
It is composed of a rotating member 7B with a.

The means for interlocking and connecting the operating tool 7 to the operating body 5 includes magnets 13 and 13' that attract each other to both rotating members 7B and 5B so that they are positioned concentrically.
, and both magnets 13 and 13' are
A state where gaps 14 and 14' are formed between the glass plate 2 and the glass plate 2 within the range of the magnetic force in order to eliminate frictional resistance to the glass plate 2 and allow the operating body 5 and the operating tool 7 to operate smoothly. It is installed in

Note that the blind 3 can be fixed at any telescopic position by the frictional force between the rotating member 7B and the sliding member 7A of the operating tool 7, and the slat 3C can be fixed at any arbitrary angle by the operating tool 7. This is done by the frictional force between the slide member 7A and the outer frame 6 at .

According to the above configuration, the expansion and contraction of the blind 3 and the slats 3C
The angle of the operating body 5 is fixed, and the rotation and sliding movement of the operating body 5 is performed with less resistance by providing a bearing 5b and a roller 5a. The blind 3 can be expanded and contracted and the angle of the slat 3C can be changed reliably and accurately by accurately following the operation.

Note that the present invention can be applied not only to windows but also to doors.
