Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roll blind with a wide range of uses.

[Prior Art] Conventional roll blinds have only a single purpose, for example, a general blackout curtain is used only as a blackout screen, and a projection blind is used only as a projection screen. Therefore, there was the inconvenience that the roll blind had to be replaced depending on the purpose. Also, in the case of a window that bends in the middle, such as a skylight or slanted window connected to a normal vertical window, it is impossible to cover both windows with one roll blind, and roll blinds must be installed separately. It was impossible.

[Purpose of the invention] The present invention provides a double roll blind that can be used for both blackout curtains and projection purposes, and can also be refracted to cover continuous skylights and vertical windows. This is an attempt to eliminate inconvenience.

[Structure of the invention] In order to achieve the above object, the feature of the roll blind of the present invention is that the roll pipe of the second roll blind is bearing-supported at the bottom of the first roll blind. A locking chamber for the tip of the screen and a storage chamber for bearing and accommodating the roll pipe are formed in the bottom. The tip of the first roll blind screen is pulled into the locking chamber and latched, the second roll blind roll pipe is rotatably supported in the storage chamber, and the screen wound around the roll pipe is pulled out from the slit in the storage chamber. . As explained in the following embodiment, the roll blind of the present invention configured in this way can be used for both a blackout curtain and a projection screen, and can also be used for a window that is refracted in the middle.

[Example] As shown in FIG. 1, the double roll blind of the present invention includes a first roll blind 10, a second roll blind 10,
The left and right brackets 11 and 12 of the first roll blind 10 are fixed to the ceiling or wall surface. A first roll blind roll pipe 13 is rotatably supported by the left and right brackets 11, 12. The screen 14 of the first roll blind is wound around the roll pipe. The lower end of the screen 14 is locked to a bottom 15, from which a second roller blind 20 hangs. A weight bar 25 is attached to the lower end of the screen 24 of the second roller blind 20.

As shown in FIGS. 2 and 3, the lower end of the screen 14 of the first roller blind 10 is shaped like a bag, into which the locking piece 16 is inserted. Locking piece 1
The lower end of the screen 14 marked with 6 is the bottom 15

is pulled out from the slit 18 on the upper surface of the locking chamber 17. The roll pipe 23 of the second roll blind 20 is inserted into the bearing chamber 19 below the bottom 15. The screen 24 of the second roll blind wound around the roll pipe 23 is pulled out from the slit 28 on the lower surface of the bearing chamber 19. bottom 15
A cap 31 is removably fixed to the side of the
One cap 31 is provided with a round hole 36 for bearing the rotating shaft 35 of the roll pipe 23, and the other cap is provided with a square shaft that engages with a square hole in the roll pipe, although not shown.

Next, the mode of use according to the purpose of the present invention will be explained.

As shown in FIGS. 4 and 5, a blackout screen 14 is wrapped around the first roller blind 10, and a projection screen 24 is wrapped around the first roller blind 20, respectively. When using it as a blackout curtain,
As shown in FIG. 4, the first roll blind 10
Only the screen 14 of the second roller blind 20 is pulled out, and the screen of the second roller blind 20 remains rolled up inside the bottom 15. Also, when using it for projection, the fifth

pull out from

As shown in FIG. 6, the double roller blind of the present invention can also be used where an inclined window is connected to a vertical window. A first roller blind 10 covers an inclined window, and a second roller blind 20 covers a vertical window. The bottom 15 is formed so as to be able to slide along guides 40 provided on the sides of the inclined window. When opening the window surface, first roll up the second roll blind 20 into the bottom 15, then slide the bottom 15 along the guide 40 and roll up the first roll blind 10. The opposite is true when blocking the window surface. The guide may be a wire that passes through the bottom.

[Effects of the invention] As mentioned above, the double roller blind of the invention can be used both as a blackout curtain and a projection screen, and can also cover refracted window surfaces that extend from skylights or slanted windows to vertical windows. It has excellent effects not found in conventional roller blinds.
