Roll screen for controlling the intensity of radiation

The present invention relates to a roll screen for adjusting the amount of light, and more particularly, a winding roll may be transferred using a cam to adjust overlapping portions of two polarizing screens to transmit, partially shield, and completely shield light, and to prevent damage to the screen. It is possible, and relates to a light screen for adjusting the light amount roll screen can be easily controlled.

In general, a roll screen is a light shielding means for opening and closing a window by a screen wound on a rotating roll by rotating the rotating roll while the one end of the screen is fixed to the rotatable rotating roll.

In addition, the roll screen is configured to be used as a substitute for woven curtains by being attached to the top of a window frame frame such as a window or a ceiling near the top of the window frame, and wound or recommended by a user's operation on a screen made of fabric or synthetic resin. It was used to block dimming through the lamp.

These roll screens are mainly used as curtains of railroad cars, and recently, they are used as a substitute for horizontal or vertical blinds in the interior spaces of homes and offices.

However, since the roll screen is shielded while transferring the screen from the top to the bottom, it is difficult to partially block the top or the bottom, and the light quantity is not easy to control.

1 is a roll screen for adjusting the conventional light quantity designed to solve the above problem, as shown in Figure 1, the winding roll is coupled to the upper support bar 11, the winding roll in the horizontal direction (15-1) ) And one end of the screen 15, on which the opaque surface 15-2 is repeatedly formed, are engaged and wound, and the other end of the screen 15 is fixed to the upper support bar 11.

That is, in the roll screen, the screen 15 is overlapped and formed downward, and the supporting rod 31 is inserted into the lower end of the overlapping portion, and the weight bar 38 is parallel to the supporting rod 31 on the lower outer side. Installed to keep the screen 15 in tension at all times.

When the winding roll is rotated forward and reverse, the light emission surface 15-1 and the light transmission surface 15-2 of the screen 15 overlap each other, and thus the light amount can be adjusted.

However, since the opaque surface 15-2 is repeatedly formed on the screen 15 of the conventional light quantity adjusting roll screen, the area of about half or more of the screen 15 is always shielded, and there is a problem inconvenient in use, and the amount of light is controlled. There was a problem that the effect is also limited.

In addition, the support rod 31 and the weight bar 38 are installed at the lower end of the overlapping portion of the screen 15, so that the screen 15 is damaged by the frictional force generated by the shanghai transport during winding and recommending the screen 15. There was a problem.

As shown in Figures 2 and 3, the light amount control roll screen of the present embodiment is the first winding roll 110, the second winding roll 120, the chain 112, the first polarizing screen 140, the second polarizing screen 150 is a light quantity control roll screen for winding the screen by operating the chain 112 provided in the take-up roll, including a conveying portion.

The first winding roll 110 and the second winding roll 120 are respectively installed on the first rotary shaft 114 and the second rotary shaft 124 fitted to the brackets formed on both ends of the upper support 100, At each one end, a first gear 111 and a second gear 121 are rotated coaxially and are engaged with each other.

Since the roll screen of the present embodiment adjusts the amount of light by transferring the hoisting roll in the axial direction, for example, the width of the first gear portion 111 is larger than the width of the second gear portion 121, so that the transfer of the take-up roll is performed. In addition, it is preferable to keep the gear portion engaged.

Therefore, since the first winding roll 110 and the second winding roll 120 can be interlocked by the engagement of the gear part, the chain and the chain wheel for conveying the screen up and down by rotating the grip roll are the first winding rolls. It is preferable that only one side of the 110 and the second winding roll 120 is formed.

In this embodiment, the chain wheel 113 is fixed to one end of the first rotating shaft 114, the first winding roll 110 is installed, the chain 112 is engaged with the chain wheel 113 is engaged with the first The winding roll 110 is rotated.

As for the 2nd winding roll 120, the 2nd rotating shaft 124 is inserted in the hollow part of the 2nd winding roll 120 so that the slidable to the axial direction on the 2nd rotating shaft 124 may be carried out. When the operator operates the chain 112, the first winding roll 110 is rotated via the chain wheel 113 and the first rotational shaft 114, so that the second winding roll 120 engaged with the chain 112 also rotates in conjunction with each other. do.

One end of the first polarizing screen 140 is wound around the first winding roll 110, and the vertical polarization part and the horizontal polarization part are alternately formed in the horizontal direction. One end of the second polarizing screen 150 is wound around the second winding roll 120, and the vertical polarization part and the horizontal polarization part are repeatedly formed in an alternating horizontal direction.

In addition, the first polarizing screen 140 and the second polarizing screen 150 are wound on the first winding roll 110 and the second winding roll 120, respectively, and are installed so as not to contact each other during winding.

That is, as shown in FIGS. 6A to 6C, in the first polarizing screen 140 and the second polarizing screen 150, the vertical polarization part and the horizontal polarization part are repeatedly formed in the horizontal direction in a vertical band shape. Since the horizontal position of the second polarization screen 150 is changed by the transfer of the second winding roll 120, the overlapping portion of the first polarization screen 140 and the second polarization screen 150 is changed.

As such, when the overlapping part is changed, the overlapping part of the vertical polarizing part and the horizontal polarizing part is shielded by the inherent characteristics of the polarizing plate which blocks light when the vertical polarizing plate and the horizontal polarizing plate overlap, and the part not overlapping is transmitted. FIG. 6A shows a light transmitting state, FIG. 6B shows a partial light blocking state, and FIG. 6C shows a full light blocking state.

In addition, the polarizing sheet 170 is formed on the inner surface of any one of the first polarizing screen 140 and the second polarizing screen 150, a polarization portion such as various patterns and pictures having an angle between the vertical polarization portion and the horizontal polarization portion It is preferable to further provide by attaching.

That is, as shown in FIG. 7, when the vertical polarizing plate and the horizontal polarizing plate overlap, the light is blocked, but when the inclined polarizing plate formed at an angle between them is not vertical or horizontal, the light is transmitted to the inherent characteristics of the polarizing plate. The polarizing sheet 170 is formed between the vertical polarizing portion and the horizontal polarizing portion by overlapping polarization parts having various angles between the vertical polarizing portion and the horizontal polarizing portion. It is possible to form a light transmitting portion such as.

The conveying part serves to press the other end with the cam and convey it in the axial direction in a state where the one end of the second winding roll 120 is held by the spring 123. When the second winding roll 120 is pressed by the transfer unit and guided and transferred on the second rotation shaft 124, the spring 123 formed on the opposite side is pressed. After that, when the pressing force of the conveying part is removed, the second winding roll 120 is conveyed in the opposite direction by the holding force of the spring 123 to return to the original position. Therefore, the second winding roll 120 is transferred to the left and right along the second rotation shaft 124 according to the pressing force of the conveying unit.

For example, as shown in FIGS. 4A and 4B, the transfer part is rotatably supported about the cam shaft 134 via a bracket 131 installed at one inner surface of the upper support 100 and rotated on a vertical plane. It is preferable to change the horizontal position of the second polarizing screen 150 by the vertical cam 130.

The vertical cam 130 is rotated in contact with the second winding roll 120 because the clamping force of the spring 123 is always applied to the second winding roll 120. Since the shape of the vertical cam 130 is elliptical, the second winding roll 120 in contact with the elliptical surface of the vertical cam 130 is transferred to the left and right on the second rotation shaft 124.

The chain wheel 133 is fixed to one end of the cam shaft 134, and the chain 132 is provided with the chain wheel 132. When the operator operates the chain 132, the cam shaft 134 is rotated, and when the cam shaft 134 is rotated, the vertical cam 130 on the cam shaft 134 is also rotated, so that the second polarization screen 150 is rotated on the second rotating shaft ( 124) to the left and right.

For another example, as shown in FIGS. 5A and 5B, the transfer part is rotatably supported about the cam shaft 160 via a cam shaft 160 vertically installed on one side top of the upper support 100 and is horizontally disposed. It is preferable to change the horizontal position of the second polarizing screen 150 by the horizontal cam 161 rotated to the image.

The horizontal cam 161 is always rotated in contact with the second winding roll 120 because the holding force of the spring 123 is always applied to the second winding roll 120. Since the shape of the horizontal cam 161 is elliptical, the second winding roll 120 in contact with the elliptical surface of the horizontal cam 161 is transferred to the left and right on the second rotation shaft 124.

When the operator operates the handle by forming a handle on the lower end of the cam shaft 160, the cam shaft 160 is rotated, and when the cam shaft 160 is rotated, the horizontal cam 161 on the cam shaft 160 is also rotated, the second polarization screen 150 ) Is moved left and right on the second rotation shaft (124).

The present invention described above can be implemented in various other forms without departing from the technical spirit or main features. Therefore, the above embodiments are merely examples in all respects and should not be interpreted limitedly.

The present invention as described above, by using a cam transporting the roll to adjust the overlap of the two polarizing screen can be transmitted, partially shielded, completely shielded, to prevent damage to the screen, easy to adjust the amount of light Provides an effect that can be

In addition, the polarizing sheet is inserted between the two polarizing screens to provide an effect of forming a pattern or a picture of various forms as a background.
