A vane plate 1a provided with a pillar body having an arbitrary shape at the center, fixed gear wheels 1b at the upper end or the lower end, and provided with extension plates by arranging the plate thickness from the left and right sides by the thickness of the plate, the belt It is configured to be rotated by a chain, a worm gear, or the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 It can be used as a fence on a veranda, a fence by arranging multiple fences, or even a shutter.

[0002]

[Prior art]

 Most of the conventional fences and belantas are fence-shaped or plate-fixed, or wall-shaped, so the inside of the fence-shaped object can be seen, and the plate-fixed ones are also visible. The wall-shaped one had the drawback of poor ventilation. Furthermore, since it is a mounting type or sliding door type shutter, the turning fulcrum is at the corner of the plate, so you can see the inside from the front even if you open it a little. It was easy, and since each plate did not rotate 180 degrees, the opaque material could not let in the sunlight.

[0003]

[Problems to be solved by the device]

 In order to eliminate the above-mentioned conventional drawbacks, in the fence and veranda, it is possible to adjust the ventilation safely without seeing the inside, and in the shutter, it is possible to adjust the ventilation while using the shutter, and even with an opaque material. The challenge is to be able to let in sunlight.

[0004]

[Means for Solving the Problems]

 The blade is a pillar with an arbitrary shape in the center or a pillar shape of a hollow body, and a plate extending from the left and right side surfaces to the left side and a plate extending to the right side are provided in front and rear by the thickness of the plate. Gears are arranged at the upper end or lower end of the plate, and the blade plates that are adjacent to each other are connected so that they partially overlap each other, and each blade plate is rotated by a chain, belt, worm gear, etc. It is intended to solve by providing such.

[0005]

[Action]

 Since the left and right blades are provided in front of and behind the center by the thickness of the blades, the blades are in a straight line with no gap in the closed state, and the blades are rotated so that they partially overlap each other. Depending on the angle, it is possible to adjust the ventilation without seeing the inside, and when it is laid on its side and used for a shutter, it can rotate 180 degrees to let in the sunlight.

[0006]

【Example】

 1 and 2 will be described with reference to the drawings. FIG. 1 is an embodiment of the present invention used for a veranda, in which each blade is rotated by turning a handle 3a. Yes, and by rotating as shown in the figure, the inside can be seen from the left side when facing the front, and the ventilation can be improved, and FIG. 2 is a closed state.

FIGS. 3 and 4 will be described. FIG. 3 is an embodiment diagram used for a shutter that also serves as a lattice. In FIG. 4, a large number of consecutive shutters can be used for a fence. FIG. 3 is a view in which the upper frame is omitted.

Referring to FIGS. 5 and 6, in FIG. 5, the center is a hollow body 1d, and the upper end is a blade plate to which a gear 1b having a hole for passing a post is fixedly attached, as shown in FIG. , The hollow portion 1d of the vane plate is fixedly connected at its upper end and lower end through the columns 2b, and the chain 3b is wound around the gear 1b fixed to each vane plate 1a, and the handle 3a is turned. As a result, each blade is rotated.

Referring to FIGS. 7 and 8, FIG. 7 shows the blade plate to which the elastic material 5a is adhered, and the blade plate is not scratched when consecutively closed as shown in FIG. It is a thing.

In FIG. 9, the handle 3a is stopped, and a fastener 3c is provided to prevent the handle 3a from rotating due to wind when the blade plate is rotated. is there.

Referring to FIG. 10, a bevel gear is fixed to the upper end of the blade plate, and a bevel gear is also arranged on the rotating shaft 3d so as to fit the bevel gear. Each blade is rotated by turning it.

As shown in FIG. 11, the plates extending to the left and right have different lengths, and are used when it is desired to reduce the rotation range of one plate.

[0013]

[Effect of device]

 In the vane plate of the present invention, the vane plates are provided to the left and right of the center, and only the thickness of the plate is moved forward and backward. Therefore, when they are rotated in series, the range where the inside cannot be seen becomes large depending on the angle. Ventilation can be adjusted, and when it is laid on its side and used for a shutter, it can rotate 180 degrees, allowing sunlight to enter. Therefore, as described above, in the fence, veranda, and shutter of the present invention, there is an effect that the ventilation can be adjusted without violating the privacy, and an effect that is useful for crime prevention is also obtained.
