And driving means 120 mounted to the frame 81 to drive the third, fourth, fifth and sixth rollers 92, 93, 102 and 103, and driving means to drive the rollers. Control means for controlling the transport distance of the film to control the 140.

Technical configurations of the first and second film members 91 and 101 are the same as those of the above-described embodiment. The frame 81 is the third and fourth rollers 92 and 93, which are spaced apart from each other by a predetermined distance, and the fifth and sixth rollers, which are adjacent to the third and fourth rollers 92 and 93, respectively and spaced apart from each other. It is possible as long as the structure capable of rotatably supporting the 102 and 103. The frame 81 may be formed in a divided structure to rotatably support the third and fifth rollers 92 and 102, and to rotatably support the fourth and sixth rollers 93 and 103, respectively. have. In addition, the frame may be integrally formed to simultaneously support two adjacent rollers 92, 102, 93, 103 as shown in FIG. 8B.

In the blocking device 80, the guide member 110 is formed with a guide groove for supporting the upper and lower edges of the first film member or the second film member is supported at both ends in the frame as in the embodiment. The guide member 110 may be formed by forming two guide grooves in a single body (see FIG. 8B).

As shown in FIG. 9, the driving means 120 drives each of the rollers, that is, the third, fourth, fifth, and sixth rollers 92, 93, 102, 103. The driven pulley 123 is installed on the drive shaft, and the drive pulley 122 is installed on the rotating shaft of the motor 121 installed on the frame 81 and has a structure in which these are connected by a belt 124 or as shown in FIG. 10. Motors 125 and 126 may be installed on the respective rollers. And another embodiment of the drive means 120 is a drive shaft and the main body of the roller on one side of the adjacent third, fifth rollers 92, 102 or 5, 6 rollers 93, 103 as shown in FIG. Two rollers may be driven by one motor by connecting one rotary shaft 127a of the motor 127 extending from both sides to the other, and connecting the rotary shaft 127b of the other side and the rotary shaft of an adjacent roller through a power transmission means. . The power transmission means may be made of conventional gears (129, 130), pulleys and belts, sprockets and chains.

12A and 12B show another embodiment of the driving means. Referring to the drawings, the first and second gears 131 and 132 and the first and second rollers 92 and 102 and the 5 and 6 rollers 93 and 103 are spaced apart from each other by predetermined intervals, respectively. An idle gear 133 supported by a link 134 rotatably installed between the first and second gears 131 and 132 and selectively engaged with the first and second gears 131 and 132, and the link. 134 or a motor 139 installed on the side adjacent thereto to drive the idle gear 133. The connection between the motor 139 and the idle gear 133 is driven pulley 135 installed on the rotary shaft of the idle gear 133 and the drive pulley 136 installed on the rotary shaft of the motor 138 and the belt 137 connecting them. It can be made by).

The control means 140 has the same structure as the above-described embodiment and may be installed on the guide member corresponding to the edge of the first and second film members.

Meanwhile, as shown in FIG. 13, the roller may be made of a flexible material and bent at a predetermined curvature. In this case, the driving means and the guide member have the same structure as in the above-described embodiment. The main body and the guide member may further include light emitting means for irradiating light to the film member.

Referring to the operation of the blocking device according to the present invention configured as described above are as follows.

In order to use the light blocking device and the partition of the window by using the blocking device configured as described above, the frame of the blocking device is installed on the props of the portions to use the window frames or partitions on opposite sides.

In this state, by driving the motor 61 installed in the first roller 31 or the second roller 32 on one side, the film member 40 is wound around the first roller 31 or the second roller 32. The light is blocked or transmitted through the window by the light blocking area or the light transmitting area of the film member 40. The boundary between the light blocking area and the light transmitting area is present in the opening area of the window so that the light flowing into the window can be partially blocked or transmitted.

At this time, the sensor 71 of the control means 70 limits the transfer position of the film member 40 by detecting a through hole or a pattern formed at the edge of the film member 40 and the microcomputer 72 detects this information. By this, the driving time or the rotation speed of the motor 41 is controlled. On the other hand, when the film member 40 wound around the roller of one side is released, the motor installed in the other roller is operated to move the film member in the reverse direction as described above. At this time, since the edges of the film member 40 are supported by the guide members 51 and 52 and supported by the wire 46 or the band 47, the film member 40 can be prevented from sagging. . By such an operation, the light blocking area and the light blocking area or the mesh layer formed on the film member 40 may be appropriately adjusted to control light blocking and light emission. In addition, since the motor 61 is installed inside the first and second rollers 31 and 32, the blocking device can reduce noise and can be made compact.

On the other hand, as shown in Figure 8 when the film member 91, 101 is formed in a double can be used to adjust the blocking and transmission of light in various ways using the overlapped corrugated member, it can double the blocking effect when used as a partition have. The driving means for driving the third to sixth rollers 93, 93, 102, 103 for supporting the first and second corrugating members 91, 101 are provided with respective motors or as shown in Figs. 11 and 12A. Since two adjacent rollers can be rotated by one, the structure can be simplified. In particular, as illustrated in FIGS. 12A and 12B, first and second gears 131 and 132 are respectively installed on the rotating shafts of adjacent rollers, and are rotated by a link 134 therebetween to the motor 138. When the idle gear 133 is driven by the idle gear 133 is rotated to be selectively engaged with the first and second gear 131, 132 it is possible to selectively drive two adjacent rollers.

As described above, the blocking device may be used in various ways, such as a blinder, a curtain, a mesh window, and a partition, depending on the installation area thereof, and at least double the film members so that the film members may be mutually transportable to adjust the blocking and transmission of various lights.

As described above, the blocking device is simple in structure and can reduce the space occupied in the frame since the motor for driving the rollers can be installed inside the roller or drive the adjacent rollers with one motor. Can be formed thin. In addition, various patterns, such as a light transmission area, a light blocking area, a mesh window, and a picture, may be realized in the longitudinal direction of the film member, thereby realizing various visible patterns.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
