Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention supports both ends of a slat rotatably relative to a frame, and adjusts the angle of the slat using an angle adjustment device provided on the frame. The present invention relates to a horizontal blind.

(Prior art) In order to adjust the angle of the slats without using a ladder cord, a horizontal blind has both ends of the slats rotatably supported on a frame body, and a slat angle adjustment device is provided on the frame body. In order to prevent the weight of the central portion from sagging, both ends of the slat are biased toward the frame body using biasing means such as coil springs to maintain tension.

(Problem to be solved by the invention) In the slat support structure as described above, the biasing force of the coil spring for tensioning the slat acts as a reaction against the frame, so the frame bends inward. This phenomenon occurs.

Structure of the invention (means for solving the problem) In order to solve the above-mentioned problems, this invention has a point-symmetrical reinforcing part 10 between the slats on the oblique side 1.
A reinforcing frame 9 having a substantially S-shaped cross section connected by a reinforcing frame 9 is arranged, and both vertical frames 5 are connected by the reinforcing frame 9.

(Function) By the above means, the deflection of both vertical frames 5 is prevented by the reinforcing frame 9, and the reinforcing frame 9 is disposed between the slats 6 and 7 without becoming an obstacle to the rotation of the slats 6 and 7.

(Example) An example embodying this invention will be described below with reference to the drawings.The frame of the blind 1 shown in Fig. 2 is designed to avoid structures such as building beams at the upper center part. In order to secure the space, the middle part of the upper frame 3 is omitted, and the middle frames 4 are respectively suspended from the ends of the upper frame 3. The middle frame 4 is formed to have a length of about 1/3 of the vertical frames 5 on both sides, and a number of short slats 6 are arranged between the vertical frames 5.
Below the middle frame 4, a large number of long slats 7 are arranged between both vertical frames 5.

Both ends of each slat 6, 7 are rotatably supported by the vertical frame 5 and the middle frame 4 via a support shaft 8, as partially shown in FIG. Each support shaft 8 is supported movably in the axial direction relative to the vertical frame 5 or the middle frame 4, and the slats 6 and 7 are tensioned by coil springs (not shown) within both the vertical frames 5 and the middle frame 4. is biased in the direction of Therefore, since the coil spring uses the vertical frame 5 or the middle frame 4 as a fulcrum and tensions the slats 6 and 7 via the support shaft 8, the reaction force acts on both frames 4 and 5 in the direction of the arrow in FIG. are doing.

A link mechanism (not shown) for rotationally driving each support shaft 8 is installed inside both vertical frames 5, and the link mechanism is moved up and down in conjunction with an operating means (also not shown). There is. Therefore, the angles of each of the slats 6, 7 are adjusted in the same phase by operating the operating stage thereof.

A reinforcing frame 9 for connecting both vertical frames 5 is provided between the slats 6 and 7 at the edge of the middle frame 4. As shown in FIG.
The character-shaped reinforcing parts 10 are connected at the oblique sides 11 to form a substantially horizontal S-shape (including Z-shape), and are fixed to the vertical frame 5 by connecting fittings 12 at both ends, and are fixed to the middle frame by similar fixing fittings. It is also fixed to the lower edge of 4.

Now, in the blind 1 as described above, the vertical frame 5 and the middle frame are connected by the reinforcing frame 9, so that the vertical frame 5 and the middle frame 4 are Deflection in the direction of the arrow in FIG. 2 can be reliably prevented by the reinforcing frame 9. Furthermore, as shown by the two-dot chain lines in FIG. 1, when the slats 6 and 7 are rotated to face in the vertical direction, the upper and lower slats 6 and 7 of the reinforcing frame 9 are connected to the reinforcing portion 10 of the reinforcing frame 9, respectively. and enters into the recess formed by the oblique side 11.

Therefore, as shown in the figure, it is possible to adjust the angle of the slats 6, 7 without any trouble while keeping the interval between the upper and lower slats 6, 7 of the reinforcing frame 9 the same as the interval between the other slats 6, 7. .

Moreover, this invention has a frame body 2 or a fourth frame body 4 in which the middle frame 4 is longer than that of the previous embodiment, as shown in FIG.
It is also possible to apply the present invention to a frame 2 in which the upper frame 3 is obliquely shaped as shown in the figure.

Effects As detailed above, this invention
A reinforcing frame 9 having a substantially S-shaped cross section, in which point-symmetrical reinforcing parts 10 are connected at oblique sides 11, is arranged between the two vertical frames 5, and the reinforcing frame 9 connects both vertical frames 5. The angle of the slats 6, 7 can be adjusted without any trouble by keeping the spacing between the upper and lower slats 6, 7 the same as the spacing between the other slats 6, 7.
The excellent effect of reliably preventing deflection of the vertical frame 5 on both sides of the frame 7 is exhibited.
