Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotatable curtain opening / closing device used when suspending a curtain such as a screen or a curtain on a window such as a long window having a vertically long shape or a bay window having a triangle or a trapezoid. .

[0002]

[Prior art]

 Conventionally, in the case of hanging a curtain openably and closably on a long window as in the above example, for example, after the curtain rail is installed along the upper window frame that constitutes the long window, it is inserted into the curtain rail as appropriate. There is a way to hang the upper edge of the curtain on each number of hanging runners.

[0003]

[Problems to be solved by the device]

 However, when opening and closing the hanging curtain as described above, the curtain is focused on one of the curtain rails to open the entire long window, but the width of the left and right window frames forming the long window becomes narrower. The projection area of the curtain becomes large, and the window surface of the long window is partially covered by the curtain that is focused on one side, and the sunlight that enters from the long window is blocked by the curtain. There is.

Further, when the curtain is focused on the outside of the window frame of the long window at the time of opening, the above problem can be solved, but the space for focusing the curtain on the side portion of the window frame. Therefore, it is difficult to hang the curtain openably and closably on the long window when the wall or pillar is close to the side of the window frame. ing.

In view of the above problems, the present invention horizontally rotates a support member around a connection bracket fixed to a mounting portion as a fulcrum, and rotates and opens / closes the entire curtain suspended at the support member at an arbitrary angle. Provide a rotary curtain opening / closing device that allows the curtain to be hung openably and closably on a window having a unique shape, and the sunlight entering from the window can be variably adjusted to an arbitrary amount of light. To aim.

The one end of the supporting member is fixed to the turning side end of the rotating side arm, and a large number of each of the arms is connected to the connecting side end surface of the one arm. The locking recesses are formed at predetermined equal intervals, and the locking projections that engage with the locking recesses are formed on the connecting side end surface of the other arm, and are formed on the one arm side. It is characterized in that it is a rotary type curtain opening / closing device in which a large number of the respective locking concave portions and the locking convex portions formed on the other arm side are engaged with and connected to each other.

[0007]

[Action]

 According to this invention, a supporting member fixed to the turning side end of the turning side arm is horizontally turned in an arbitrary direction around a connecting portion of a fixed side arm and a turning side arm which constitute a connecting bracket. . In other words, with the connecting part of each arm as the center, the engagement of the many locking recesses formed at the connecting side end of one arm with the locking protruding part formed at the connecting side end of the other arm. By sequentially displacing the position, the support member can be horizontally rotated in an arbitrary direction. Moreover, when the support member is stopped to rotate to an arbitrary position, a large number of respective locking concave portions and locking convex portions formed at the connection side end portion of each arm are engaged and fixed to each other and hung on the supporting member.
