Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a power supply structure for an electric blind attached to a sash rotatably supported on a window frame.

(Prior art) Conventionally, in a rotary sash in which a glass sash can be rotated horizontally or vertically about a rotation axis, for example, the sash has a double glass structure and a blind is hung between the double glasses. Some blinds are supported underneath and can be raised and lowered and adjusted in angle using a motor built into the upper stile of the rotating sash.

(Problem to be solved by the invention) In the case of blinds built into a rotating sash as described above, when commercial power is used as the power source for the motor, the power cord led from the sash is connected to a power source installed on a wall, etc. It is configured to be connected to an outlet. Therefore, the power cord is not aesthetically pleasing, and when the sash is rotated, it is necessary to disconnect the power cord from the outlet, which is troublesome. Furthermore, if a DC power source is housed within the upper stile or vertical stile of the double glass shoji screen, and the DC power source is used to drive a DC motor, there is a problem in that the maintenance and management of the DC power source is troublesome.

Structure of the invention (means for solving the problem) In order to solve the above problem, this invention suspends and supports a blind from a frame of a sash that is rotatably supported on a window frame, and the blind is suspended from a sash frame. In a double glass sash in which a blind is suspended and supported from a stile and the blind is driven by a motor installed inside the stile, the stile sides of the sashes 2 and 23 and the side surfaces of the window frames 1 and 22 corresponding to the stile sides. A connector 1 for supplying power to the motor 7 between the
0 and 11 are provided.

(Function) With the above means, when the sashes 2 and 23 are rotated and closed, the connectors 10 and 11 are connected and the motor 7
It becomes possible to supply power to.

(Example) Hereinafter, a first example embodying this invention will be explained according to Figs. 1 and 2. The shaft rotating sash 2 disposed between the window frames 1 has a double glass structure. The vertical center portion of the vertical stile is supported by a pivot shaft 3 protruding from the window frame 1 so as to be rotatable in the vertical direction. In addition, the shaft-rotating sash 2 has a blind 4 suspended between the double glass windows, and the blind 4 is suspended from a drive shaft (not shown) rotatably supported within the upper stile 5 of the shaft-rotating sash 2. The slat 6 is supported below, and by rotationally driving its drive shaft, the slat 6 can be raised and lowered and the angle can be adjusted.

A motor 7 for rotationally driving the drive shaft is disposed inside the upper stile 5 of the shaft rotating sash 2. When the motor 7 rotates in the forward direction, the slat 6 is rotated and pulled up, and when the motor 7 rotates in the reverse direction, the slat 6 is lifted up. It is designed to be rotated in the opposite direction and then lowered.

As shown in FIG. 1, the upper frame 8 constituting the window frame 1
The outdoor side of the sash 2 projects slightly downward to form an engaging portion 9, and the upper stile 5 of the shaft rotating sash 2 comes into contact with the engaging portion 9, so the shaft rotating sash 2 only moves in the direction shown by the arrow in the figure. It is rotatable. The engaging part 9
A female connector 10 is attached to the engaging portion 9 on each opposing surface of the upper stile 5, and when the shaft rotating sash 2 is rotated in the vertical direction as shown in FIG. 11 are coupled together, and if the shaft rotating sash 2 is rotated in the direction of the arrow in the figure, the coupling between both the connectors 10 and 11 can be released.

The male connector 11 is connected to the motor 7 in the upper frame 5, and the female connector 10 is connected to a control box 12 provided on a wall or the like as shown in FIG. The control box 12 is supplied with 100V commercial power, and the control box 1
2 steps down the commercial power supply to an AC or DC power supply voltage that matches the rating of the motor 7, and operates the up switch 13 and down switch 14 provided on the front of the commercial power supply to generate a current or current that rotates the motor 7 in the normal direction. A current for reversing the rotation is supplied to the motor 7. In addition, up switch 1
3 and the lowering switch 14 may be provided on a vertical stile of the shaft rotating sash 2 or the like.

Now, the shaft rotating sash 2 configured as above
can be opened and closed by rotating around the pivot shaft 3, and as shown in FIG. 1, when the connectors 10 and 11 are rotated in the vertical direction, both connectors 10 and 11 are connected to each other. Then, in this state, turn up switch 1
3 and the lowering switch 14, the motor 7 is rotated forward or reverse, and the angle of the slat 6 is adjusted and raised or lowered.

As described above, this shaft rotating sash 2 is connected to the motor 7.
Connect male connector 1 to upper stile 5 to supply power to
1 is provided, and a female connector 10 is provided on the engaging portion 9 of the window frame 1, so that when the connectors 10 and 11 are rotated in the vertical direction, both connectors 10 and 11 are automatically connected, and the slat 6 is raised and lowered. and the angle can be adjusted, and in this state both connectors 10 and 11
is hidden behind the upper stile 5 and is not exposed in front of the shaft rotating sash 2.

Therefore, by using the motor 7 as a drive source for driving the blind 4, this shaft-rotating sash 2 can raise and lower the slat 6 and adjust the angle very easily. Since there is no need to house a power source, assembly is easy. Also, when the shaft rotation sash 2 is closed, both connectors 10 and 11 are automatically connected, and when the sash 2 is rotated and opened, both connectors 10 and 11 are automatically separated, so that power is supplied to the motor 7. The device does not interfere with the opening and closing operations of the sash. Furthermore, commercial power can be used as a power source for the motor 7, making maintenance and management of the power source unnecessary.
Exposure of 0 and 11 can be prevented.

Next, a second embodiment embodying this invention will be explained with reference to FIGS. 3 and 4. In the double glass sash of this embodiment, the outer sash 21 is connected to the window frame 22.
The inner sash 23 is rotatably supported on the window frame 22 by a hinge 24 on one side. A blind 4 is suspended and supported on the inner sash 23, and a female connector 10 and a male connector 11 similar to those in the embodiment described above are provided on the facing surfaces of the vertical stile 25 and the window frame 22 on the opposite side of the hinge 24. ing. The male connector 11 is connected to the motor 7 that drives the blind 4 by an extensible cord 26, and is connected to the vertical stile 2 as shown in FIG.
5, the female connector 10 is configured to be detachable from the connector 10.
is connected to a control box similar to the previous embodiment.

In such a double glass sash, the inner sash 2
By opening and closing the connectors 3, both the connectors 10 and 11 are connected or separated, so the same effect as in the previous embodiment can be obtained, and the inner sash 2
3 to separate the connectors 10 and 11, if the male connector 11 is removed from the vertical frame 25 and fitted to the female connector 10, power can be supplied to the motor 7 by operating the switch. blinds can be opened and closed.

Effects of the invention As detailed above, this invention
Power can be supplied to the blind drive motor 7 housed in the sashes 2, 23 which are rotatably supported by the sashes 2, 23 without interfering with the rotational operation of the sashes 2, 23. It is possible to automatically connect and separate the connectors 10 and 11 based on the rotation operation, and also prevent the exposure of the connectors 10 and 11 for supplying the connectors 2 and 23.
It exhibits excellent effects that can improve the aesthetic appearance of the skin.
