Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blind sheet slip-type blinds apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind seat slip tilting type blind apparatus, and more particularly, to a blind apparatus for blind seat slip tilting type blind apparatus, It is.

Discloses a blind sheet in which opaque blind sheets are generally spaced apart from each other in a transverse direction at regular intervals between transparent front and back sheets.

When the blind sheet is overlapped with the front and rear sheets, the light is blocked. When the blind sheet is positioned horizontally, the light passes through the blind sheet as much as possible. When the blind sheet is overlapped with the front and rear sheets, And the degree to which the outside can be seen is adjusted.

The applicant of the present application has found that a blind sheet 400 composed of transparent front and back sheets 412 and 411 as disclosed in Japanese Patent No. 1139294 is applied to a sheet winding pipe 310 And the blind sheet 400 having the weight bar 420 at the lower end thereof is loosened or rewound according to the loading operation of the operating line 210, A tilting pipe 320 installed parallel to one side of the sheet take-up pipe 400 and guiding the blind sheet 400 in an idle state, The tilting pipe 320 operated by the operation line 210 is operated to brak the tilting pipe 320 to frictionally stop the conveyance of the front sheet 412 of the blind sheet 400 and to slide the back sheet against the front sheet 412 And a tilting braking means for controlling the degree of overlapping of the front and rear sheets of the blind sheet 400 so as to shield and transmit the blind sheet 400.

The tilting braking means includes a braking lever 330 for braking the operation line 210 so as to control the rotation of the tilting braking gear 321 coupled to the tilting pipe 320, And when the return rotary plate 230 is electromagnetically coupled to the operation output body 220 by the return clutch 240 after the operation of the braking lever 230 is completed, And a returning protrusion 231 for pushing the return cam 333 of the return spring 330 to rotate the brake.

In the conventional blind apparatus configured as described above, when the blind sheet 400 is to be wound or tucked by the operation string 210, when the shading and the shade are to be adjusted, the operation lever 210 is used to adjust the braking lever 330 so that the tilting braking gear 321 is engaged by the braking protrusion 331 of the braking lever 330 to restrict the rotation of the tilting braking gear 321.

When the operation line 210 is operated in the above state, the rear sheet 412 flows along the front sheet 411, which is frictionally restrained to the tilting pipe 320, so that the shade or the shade can be controlled.

When the operation rod 210 is operated to continuously rotate the entire operation string 220, the return projection 231 of the return rotary plate 230 pushes the return cam 333 of the braking lever 330, The protrusion 331 is disengaged from the tilting brake gear 321 and the tilting pipe 320 is freely rotated.

However, in the conventional blind device as described above, the outer diameter of the tilting pipe 320 is small compared to the sheet winding pipe 310 and the winding length of the rear sheet wound on the tilting pipe 320 is short, The frictional force is not sufficient and the tilting operation is not smoothly performed.

Accordingly, the present invention solves the problem that the backing sheet wound on the tilting pipe in the conventional blind apparatus is not sufficiently shortened to cause a sufficient tilting force, as described above.

That is, the present invention provides a blind apparatus comprising a winding length increasing means for a tilting pipe.

Therefore, according to the present invention, since the tilting pipe winding length of the rear sheet is increased by providing the tilting pipe winding length increasing means, the frictional force between the tilting pipe and the back sheet is increased, and the tilting operation is clearly performed.

FIG. 7 is a side view showing still another embodiment according to the present invention. FIG.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention maximizes the winding length of the tilting pipe in the back sheet during the tilting operation of the blind so that the tilting operation can be clearly performed.

That is, according to the present invention, a blind sheet 400 composed of transparent front and rear sheets 412 and 411 is wound on a sheet winding pipe 310 which is rotated forward and backward by an operating line 210, The blind seat 400 having the weight bar 420 at the lower end thereof is loosened or rewound by the loading operation; A tilting pipe 320 installed parallel to one side of the sheet take-up pipe 400 and guiding the blind sheet 400 in an idle state, The tilting pipe 320 operated by the operation line 210 is operated to brak the tilting pipe 320 to frictionally stop the conveyance of the front sheet 412 of the blind sheet 400 and to slide the back sheet against the front sheet 412 And a tilting braking means for causing the blind seat (400) to be shielded from light and to transmit light according to the degree of overlapping of the front and rear sheets of the blind seat (400) or the overlap amount of the awning sheet (413); And means for increasing the winding length of the tilting pipe.

The tilting pipe 320 may be formed by forming the tilting pipe 320 with a diameter of 1/2 to 2/3 or more of the diameter of the sheet winding pipe 310.

Another embodiment of the wrapping length expanding means of the tilting pipe 320 is a wrapping length expanding pipe (not shown) which presses and presses the upper surface of the back sheet 412 between the tilting pipe 320 and the sheet winding pipe 310 1).

The center of the tilting pipe 320 and the center of the sheet winding pipe 310 are preferably located at the center of the center of the tilting pipe 320.

Another embodiment of the wrapping length expanding means of the tilting pipe 320 is that the blind sheet 400 is taken out from the lower portion of the sheet winding pipe 310 and wound on the upper portion of the tilting pipe 320 You can.

Hereinafter, the operation of the present invention will be described.

In the blind apparatus as described above, The tilting pipe 320 is provided with a tilting pipe 320 having a diameter of 1/2 to 2/3 or more of the diameter of the sheet winding pipe 310 The winding length of the blind sheet 400 wound in the sheet winding pipe 310 is increased due to the enlargement of the diameter of the tilting pipe 320 so that the frictional force between the front sheet 411 and the tilting pipe 320 is maximized The braking of the front seat 411 by the tilting pipe 320 is clearly performed.

Further, in another embodiment of the present invention, in a blind apparatus, The tilting pipe 320 is provided with a winding length increasing means for rolling the length of the tilting pipe 320 between the tilting pipe 320 and the sheet winding pipe 310 in a rolling contact with the upper surface of the rear sheet 412 The length of the winding wound around the tilting pipe 320 of the blind sheet 400 pressed by the winding length expanding pipe 1 becomes longer and the front sheet 411 and the tilting The frictional force of the pipe 320 is maximized and the braking of the front seat 411 by the tilting pipe 320 is clearly performed.

Further, in a blind apparatus according to another embodiment of the present invention, If the blind sheet 400 is taken out from the lower portion of the sheet winding pipe 310 and wound around the upper portion of the tilting pipe 320, The blind sheet 400 wound or unwound from the lower side of the winding pipe 310 is taken up from the lower portion of the tilting pipe 320 and wound up to a longer length so that the frictional force between the front sheet 411 and the tilting pipe 320 So that the braking of the front seat 411 by the tilting pipe 320 is clearly made.
