Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a double-opening curtain opening / closing device capable of electrically opening / closing a double-opening curtain of a window of a car or a window of a house.

[Conventional technology]

A conventional device of this type is, for example, Japanese Patent Laid-Open No. 57-1257.
There is one disclosed in Japanese Patent Publication No. 14.

In this device, the curtain is openably and closably connected via a hook to a suspender that is movable along a rail fixed to the upper edge of the window of the vehicle body, and a loop-shaped belt is formed inside the rail. It is installed so that the direction is horizontal.

The belt has holes at equal intervals, in which holes drive gears driven by a motor mesh, and are hung between the drive gear and a driven gear pivotally attached to the other end of the rail. , It is designed to move in the rail.

When opening and closing the curtain, the belt is moved through the drive gear by the operation of the motor, which allows the gear to open and close the curtain.

[Problems to be solved by the device]

However, in the conventional device as described above, it is convenient to open and close a single-sided curtain.
It is not suitable for double-opening curtains that open and close the curtains in opposite directions.

That is, in order to use the double-opening curtain type, a motor, a belt, etc. are separately required, which complicates the configuration and increases the rail cross-sectional shape.

b), rotating the drive pulley (17) clockwise through the gear (17a) to move the belt (23) in the B direction,
By moving the drive member (24) and the second drive member (28) in a closing direction toward each other, the curtain (K1)
(K2) can move in the closing direction at the same time.

[Effect of device]

As described above, the present invention has the following effects.

(A) The width direction of the belt is oriented in the vertical direction, and the coupling structure of the belt and the first and second driving members is the above-described structure, so that the belt is provided with the first and second driving members on both sides of the opening. It is possible to reduce the thickness of the rail that has the first and second storage portions and tends to have a large left and right width.

(B) Further, it is only necessary to secure a space corresponding to the sum of the width of the belt and the thickness of the portion of the first and second drive members straddling the supporting portion of the rail, inside the rail. Therefore, the vertical dimension of the rail can be significantly reduced.

(C) Due to the effects of (a) and (b) above, the vertical and lateral dimensions of the rail can be reduced to reduce the size of the entire rail, and the rail can be mounted in a narrow window frame or the like with good appearance. .

(D) With the structure as described in claim 2, it is not necessary to separately provide a coupling means for coupling the belt in an endless manner, and when the belt is permanently stretched or the like,
The effective length of the belt can be adjusted in this part.
