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 Publication No. 59-12337, two movable supports are movably attached to a cane that is supported at the bottom of the window so that it can move up and down, and it is also arranged at the top of the window so that it can be rolled up and rolled out. The sheet is connected to the second movable support via the first movable support, and by rotating the rod and moving the first and second movable supports, the sheet is turned outward into a dogleg shape. It is bent 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]

A pair of left and right guide rails that guide a support frame connected to the leading edge of a sheet that is wound up and fed out by a winding device, and a second guide rail is connected to the lower part of the fixed first guide rail so as to be vertically movable. The front frame is horizontally connected between the tip ends of the second guide rail, and a locking groove is formed at the lower end of the second guide groove of the second guide rail to allow the support frame to be freely engaged and detached. A locking device is provided on the front frame and the lower part of the window to lock the second guide rail at a position in line with the first guide rail, and by moving the second guide rail up and down, the lower part of the window is opened. The upper part of the window can be covered with a sheet, and the entire outside of the window can be covered with the sheet so as to be close to and approximately parallel to the outside surface of the window. It is designed so that it can be locked in the correct position.

[Effect of idea]

Rotate the second guide rail 13 downward to align the guide rail 11 with the first guide rail 12.
In this state, if the support frame 7 is moved along the guide groove of the guide rail 11 and engaged with the locking groove 15a of the second guide groove 15, the sheet 4 covers the entire outside of the window C. When the sheet 4 is released from the locking groove 15a, the sheet 4 can be wound up by the winding device 5 and the entire outside of the window C can be released.

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.

Further, the first guide rail 12 is fixed, and the second guide rail 12 is fixed.
Since the guide rail 13 rotates up and down, rattling and wobbling movements are reduced compared to when the entire guide rail 11 rotates, and moreover, the distance between the tips of the pair of left and right second guide rails 13 is reduced. Since the front frame 18 is horizontally connected, the pair of left and right second guide rails 13 are firmly connected, and together they act on the seat 4 when the second guide rail 13 is rotated upward. There is no rattling due to wind pressure, there is no twisting of the guide rail 11, especially the second guide rail 13, and the left and right second guide rails 13 can be rotated up and down synchronously.

Also, a locking member 24 constituting the locking device 26
By engaging the locking member 25 with the locking member 25, the second guide rail 13 is locked in a position where it is in a straight line with the first guide rail 12, and the first guide rail 12 and the second guide rail 13 are aligned in a straight line. It can hold the support frame 7 between the first guide rail 12 and the second guide rail 1.
Since the second guide rail 13 can move smoothly without rattling when moving over the length 3, the operation of winding up and feeding out the sheet 4 with the guide rail 11 in a straight line can be performed smoothly.
