Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for opening and closing the sheet of an external blind that covers and opens the outside of a window with a sheet.

[Conventional technology]

As shown in Japanese Utility Model Publication No. 53-31054 and Japanese Utility Model Publication No. 59-12337, a wheel attached to the top of the window winds up a sheet and allows it to be freely rolled out. External blinds whose outsides are covered with a sheet or left open are known.

[Problem that the invention attempts to solve]

With the former type of external blind, the sheet can be opened and closed by winding it up and letting it out by operating the string, but this requires a complicated link mechanism, which makes the overall structure complicated. Since one end of a wide sheet in the width direction is operated by a string, it is difficult to move the sheet uniformly across the width even if both ends in the width direction are linked using links. Put it away.

In the case of the latter type of external blind, the sheet is wound up and unrolled by moving the first and second movable supports along the left and right poles, which makes the operation very troublesome. Since the window has inner and outer shoji built in, it is not possible to move the first and second movable supports simultaneously along the left and right handrails, but they must be moved from one side. , the other side of the first and second movable supports will be strained against the crutch, making it impossible to move smoothly.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sheet opening/closing device for an external blind that allows the sheet to be moved smoothly from the indoor side of the window and has a simple structure.

[Means and actions for solving problems]

A support frame is connected to the sheet being wound up and fed out by a winding device, and this support frame is made vertically movable along guide grooves of left and right guide rails,
A handle is provided in the longitudinal center of the support frame facing toward the window, and this handle is made longer than the width of the mating stile of the inner and outer shoji of the window, so that even if either the inner or outer shoji is opened, the window will not close. The support frame can be moved up and down smoothly by holding the handle from the inside of the room.

〔Example〕

As shown in Figures 2, 3, and 4, a window frame 1 is attached to the opening B of the building frame A, and inside and outside shoji 2 and 3 are constructed in sliding fashion within this window frame 1. A screen-shaped blind D is attached to the outside of the window C.

The screen-type blind D has a sheet 4,
It is equipped with a winding device 5 that feeds out and winds up the sheet 4, a pair of left and right guide members 6, and a support frame 7 that moves up and down along the pair of left and right guide members 6. connected.

The winding device 5 includes a winding wheel 9 in a case 8.
The winding wheel 9 is rotatable and rotatably biased in the direction of winding up the sheet 4, and the base edge of the sheet 4 is wound around the winding wheel 9.
A case 8 is attached to the outer surface of the building frame A above the upper frame 1a of the window frame 1.

The guide member 6 consists of a mounting frame 10 and a guide rail 11, and the mounting frame 10 is attached to the vertical frame 1b of the window frame 1.
The guide rail 11 is attached to the outer surface of the building frame A on the side, and consists of a first guide rail 12 and a second guide rail 13. The groove 14 and the second guide groove 15 are formed continuously in the vertical direction, and the support frame 7 is vertically movable across the first guide groove 14 and the second guide groove 15. 12 is fixed to the upper part of the mounting frame 10, and a bracket 16 is attached to the lower end thereof.The upper end of the second guide rail 13 is connected to this bracket 16 with a pin 17 so as to be movable up and down, and a pair of left and right The second guide rail 13,1 of
A front frame 18 is horizontally connected between the lower ends of the three.

An arm bracket 20 is attached to the upper and lower middle of the pair of left and right mounting frames 10, 10, respectively,
A pair of left and right arms 2 on each arm bracket 20
1 is supported by pivot pins 22 so as to be movable up and down, and a horizontal rod 23 is horizontally supported between the tips of the pair of left and right arms 21, and this horizontal rod 23 has a circular cross section. The pair of left and right arms 21 are pipe-shaped and are rotatable between a substantially horizontal protruding position in which they protrude outward and a retracted position in which they are substantially parallel to the guide member 10.

A locking member 2 is provided at the longitudinal center of the front frame 18.
A lock receiving member 25 is attached to the outer surface of the building frame A below the lower frame 1c of the window frame 1 to connect the second guide rail 13 to the first guide rail 12.
This constitutes a locking device 26 that locks and fixes in the linear position.

A hook 27 is attached to the upper part of the longitudinal center of the front frame 18, and an arm member 28 is swingably supported on the outer surface of the building frame A below the lower frame 1c of the window frame 1. By engaging the tip 28a of the member 28 with the hook 27, the second guide rail 13 can be held in the upwardly rotated position.

First and second guide grooves 1 are provided at both ends of the support frame 7.
4 and 15 are respectively attached, and locking grooves 14a and 15a are formed in the first guide groove 14 and the second guide groove 15, respectively. When the sliders 29 are fitted to the sliders 14a and 15a, the support frame 7 can be locked to prevent it from moving upward.

Further, a handle 30 is attached to the support frame 7 so as to face the window C, and as shown in _FIG . It is attached to the longitudinal center of the support frame 7, and left and right hand grips 31 are formed at both ends of the support frame 7 in the longitudinal direction. , 3 are positioned to the left and right of the matching frames 2a, 3a when closed.

Because of this, by holding the handle 30 and moving it up and down, the support frame 7 can be moved up and down in parallel without diagonally left and right, and the support frame 7 can be moved diagonally with respect to the guide groove of the guide rail 11. The support frame 7 can be smoothly moved up and down to wind up and unwind the sheet 4 without becoming twisted or twisted.
Even if either the inner or outer shoji 2, 3 is opened, the seat 4 can be opened and closed from the indoor side because it can be moved up and down by holding the handle 30.

Note that the handle 30 may be integrated with the support frame 7.

In the above external blind, the second guide rail 13 is rotated linearly with the first guide rail 12 to make the guide rail 11 straight, as shown in FIG. 5a, and the support frame 7 slider 2

If the position is changed, the seat 4 can be pushed outward by the horizontal rod 23 to form a substantially doglegged shape, creating a large space a between it and the window C, increasing the living space. 11 is made straight and the slider 29 is engaged with the locking groove 14a of the first guide groove 14, the outer upper surface of the window C can be covered and the lower part can be opened. In this state, as shown in FIG. By rotating the arm 21 to the protruding position, the seat 4 can be pushed into a substantially dogleg shape to form a space b between the outer surface of the window C and the seat 4, and the second guide rail 13 can be moved as shown in FIG. 5e. The slider 29 is projected outward and rotated to make the guide rail 11 into a dogleg shape, and the slider 29 is inserted into the locking groove 15a of the second guide rail 15.
When engaged, a space c can be formed between the seat 4 and the outer surface of the window C, and can be opened downward.In this state, if the arm 21 is rotated to the protruding position as shown in FIG. A large space d can be formed between the outer surface of the window C and the sheet 4 by pushing the sheet 4.

In this way, the outer surface of the window C can be covered with the sheet 4 in various shapes and can be used depending on the purpose.

[Effect of idea]

By holding the handle 30 and moving it up and down, the support frame 7
The left and right guide rails 11 are not diagonal to the left or right.
The sheet 4 can be moved up and down in parallel along the guide groove of the window C, and the sheet 4 can be easily rolled up from the indoor side of the window C, and the sheet 4 can be opened and closed by being unrolled.

Furthermore, since the handle 30 is longer than the width of the mating frames 2a, 3a of the inner and outer shoji 2, 3, by opening either the inner or outer shoji 2, 3, the handle 30 can be opened from the indoor side. This makes it easier to open and close the seat 4. In other words, inner and outer shoji 2,
Since there is no need to consider which one of the seats 3 to open, opening and closing the seat 4 becomes easy.

Further, since it is sufficient to simply provide the left and right guide rails 11, 11 and the support frame 7, the structure for opening and closing the seat 4 becomes simple.
