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, so a space can be created between the outside surface of the window and the sheet, increasing the living space. The lower part can be left open and the upper part can be covered with a sheet, which improves ventilation, but on the other hand, since the cane is rotatably connected to the bottom of the window, the upper part of the cane is far away from the window. Since it protrudes from the seat, it looks bad.

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]

As shown in FIG. 11, a lock hole 58 is formed in the second guide rail 13, and a plurality of pin holes 59 are formed in the bracket 16 on a circular arc trajectory centered on the pin 17. Hole 5
9 may be fitted into the lock hole 58 to restrict the rotation of the second guide rail 13, and in this way the second guide rail 13 can be fixed at different angles.

[Effect of idea]

Since the first guide rail 12 is fixed and the second guide rail 13 rotates up and down, rattling and wobbling movements are reduced compared to when the entire guide rail 11 is rotated. The front frame 1 extends between the tips of the second guide rails 13.
8 are horizontally connected, the pair of left and right second guide rails 13 are firmly connected, so that when the second guide rails 13 are rotated upward, the wind pressure acting on the seat 4 can prevent the seat 4 from rattling. In addition, the guide rail 11, especially the second guide rail 13, is not twisted, and the left and right second guide rails 13 can be rotated vertically in synchronization.

In addition, the second guide rail 13 is rotated downward to be aligned with the first guide rail 12 so that the guide rail 11 is in a straight line, and in this state, the support frame 7 is moved along the guide groove of the guide rail 11. If the sheet 4 is engaged with the locking groove 15a of the second guide groove 15, the entire outer surface of the window C can be covered with the sheet 4, and the locking groove 1
Once removed from 5a, the sheet 4 can be wound up by the winding device 5 and the entire outside of the window C can be opened.

Therefore, by moving the support frame 7 up and down along the guide rail 11, the entire outer surface of the window C can be covered or uncovered with the sheet 4, making the operation simple.

Further, by rotating the second guide rail 13 upward to make the guide rail 11 into a dogleg shape, the lower part of the window C can be opened to improve ventilation, and the lighting can also be improved. By engaging with the locking groove 15a of the second guide groove 15, the seat 4 is made oblique to form a space between the outer surface of the window C and the seat 4, thereby increasing the living space. There are no protruding members, and the seat 4 and front frame 18 are only visible from the outside, resulting in a good-looking exterior.
