Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an external blind installed outside a window.

[Conventional technology]

As shown in Japanese Utility Model Publication No. 53-31054, a sheet wound around a drum is connected to a rod horizontally suspended at the end of an arm, and by rotating this arm up and down, the sheet is wound up and unrolled to open the window. The outside is covered with a sheet or left open.

As shown in Japanese Utility Model Application Publication No. 59-12337, two movable supports are movably attached to a cane supported at the bottom of the window so as to be movable up and down, and are arranged at the top of the window so that they can be rolled up and rolled out. The sheet is connected to the second movable support via the first movable support, and the sheet is turned outward by rotating the arm and moving the first and second movable supports. It is bent into a shape to cover a window.

As described above, various types of external blinds are known in which the outside of the window is covered with a sheet or left open.

[Problem that the invention attempts to solve]

With the former type of external blind, when you want to cover or release the outside of the window with a sheet, you have to rotate the arm, so you cannot roll up only the sheet and extend it to cover or release the outside of the window. This makes the operation cumbersome.

With the latter type of external blinds, the sheet is bent into a dogleg shape and protrudes outward, creating a space between the outside surface of the window and the sheet, increasing the living space. Since the cane is rotatably connected to the lower part of the window, the upper part of the cane is far away from the window and protrudes from the seat, resulting in an unsightly appearance.

Therefore, an object of the present invention is to provide a practical external blind that can solve the various problems mentioned above.

[Means and actions for solving problems]

A support frame is connected to the leading edge of the sheet being wound up and fed out by a winding device, and this support frame is supported so as to be able to move up and down along the guide grooves of a pair of left and right guide rails, and an arm is attached to each guide rail. The projecting position and the storage position are connected so that they can move up and down, and the horizontal rod is horizontally connected between the tips of the left and right arms, and the support frame is removably engaged with the lower end of the guide groove. By forming a groove and moving the support frame up and down along the guide groove, the sheet can be fed out and rolled up, and by engaging the support frame with the locking groove and rotating the arm to the protruding position, the sheet can be rolled out horizontally. The sheet can be bent outward into a dogleg shape by pushing the sheet with a rod.

When inserting the arm 21 between the locking protrusions 80 and 80, the arm 21 is slightly elastically deformed.
A lever 83 is supported in a lever bracket 82 attached to the building frame A so as to be movable up and down, and a notch 84 formed at the tip of the lever 83 is attached to the arm 21.
The arm 21 may be engaged with a locking pin 85 to prevent the arm 21 from rotating upward at the protruding position.

In addition, as shown in FIG. 12, the second guide rail 11 may be integrally elongated, and its upper part may be connected so as to be movable up and down. In this way, the guide rail 11 can be rotated upward. An opening can be formed at the bottom to improve ventilation.

[Effect of idea]

By rotating the arm 21 to the storage position and moving the support frame 7 up and down along the guide grooves of the left and right guide rails 11, only the sheet 4 is wound up.
The sheet 4 can be rolled out to cover the entire outside of the window C with the sheet 4, and the sheet 4 can be released, making the operation easy.

Also, from the state where the support frame 7 is engaged with the locking groove 15a and the outside of the window C is covered with the sheet 4, the arm 2
By rotating the sheet 1 to the protruding position, the sheet 4 is pushed by the horizontal rod 23 and bent outward in a substantially doglegged shape, creating a space between the sheet 4 and the outer surface of the window C, thereby creating a living space. It can be made wider, and since the sheet 4 is pushed by the horizontal rod 23, there is no member protruding outward from the sheet 4, resulting in a good appearance.
