KR200419344Y1 - A counter weight bar for roll screen - Google Patents

Abstract

The present invention relates to a counter weight bar for a roll screen, in which two fixed and transparent screens in the vertical direction and a fixed screen and a movable screen are alternately arranged so that they can be applied to a roll screen to be wound or unwound together with a winding rod. Two spaces 14 and 16, which are connected to the slits 10 and 12, respectively, are formed in the upper half, are separated from the spaces 14 and 16, and a heavy object can be added. Roll screen counter weight is characterized in that the space portion 18 is formed in the lower half.

The present invention has the advantage of being able to smoothly move the movable screen in the lateral direction as well as tension both the fixed screen and the movable screen unfolded in the roll screen.

Description

A counter weight bar for roll screen}

1 is an exploded perspective view of a counter weight bar and a roll screen according to the present invention;

Figure 2 is a front view illustrating a state of use of the counter weight bar according to the present invention.

3 is an enlarged cross-sectional view of a portion of line I-I of FIG. 2;

The present invention relates to a counter weight bar for a roll screen that tensions a screen released from a winding rod, and more specifically, to a roll screen filed by the inventor of the present application as Utility Model Registration No. 20-2006-0007791. A counter weight bar for a suitable roll screen is provided.

The roll screen includes a fixed screen in which the transverse portion in the vertical direction and the opaque portion are alternately in the width direction, and a movable screen in which the transmissive portion in the vertical direction and the opaque portion corresponding to the fixed screen are alternately in the width direction together with the winding rod. It is wound or unrolled, and the movable screen is supported on the take-up rod so as to move in the lateral direction, and the movable screen is moved laterally so that the light projecting portion of the fixed screen overlaps with the light transmitting portion of the movable screen. Since the lower part of the fixed screen should be fixed to the counter weight bar because it is adjusted like a blind, the lower part of the movable screen is fixed to the counter weight bar and can also be horizontally adjusted so that the degree of shading can be smoothly adjusted.

Therefore, the conventional counterweight bar, which is simply fixed at the lower end of the screen to tension the screen released from the winding rod, is not suitable for a roll screen consisting of a fixed screen and a movable screen.

It is an object of the present invention to provide a counterweight bar for a roll screen suitable for a roll screen in which the fixed screen and the movable screen, which are alternately formed in the transverse direction and the transmissive part in the vertical direction, are wound or unwound together with the take-up rod.

The present invention will be described in more detail by way of example.

1 to 3, two separate spaces 14 and 16 connected to two parallel slits 10 and 12, respectively, are formed in the upper half, as illustrated in FIGS. The space portion 18, which is separated from the space portions 14 and 16, to which a heavy object can be added, is formed in the lower half.

In the present invention, the two slits 10, 12, two spaces 14, 16, and the other space 18 have an inner horizontal wall portion 20 and the horizontal wall portion 20. It is formed by the vertical wall portion 22 extending from the center to the top.

In the present invention, the screen fixing rod 24 at the lower end of the fixing screen A, in which the transmissive part a and the opaque part b in the vertical direction are alternately formed in the width direction, can be fixed to one space 14. The other space portion 16 has a fixed screen A and a corresponding light emitting portion a 'and an opaque portion b' at the lower end of the movable screen B formed alternately in the width direction. The screen fixing rod 26 is loosely fitted so as to be movable in the transverse direction.

In the present invention, the inner wall vertical wall portion 22 providing the two slits 10, 12 moves the movable screen B in the horizontal direction to the left and the right as illustrated in FIG. It prevents the movable screen (B) and the fixed screen (A) from contacting each other when tightening, thereby tensioning both the unfolded fixed screen (A) and the movable screen (B), while moving the movable screen (B) in the horizontal direction of the left and right sides. It helps to move smoothly.

In the drawings, reference numeral 28 is a winding rod, 30 is a bracket assembly rotatably supporting the winding rod, and 32 is a rotation mechanism of the winding rod 28.

The present invention applies both the fixed screen and the movable screen which are unfolded when the fixed screen and the movable screen, which are alternately formed in the transverse direction in the vertical direction, to the roll screen which is wound or unrolled together on the winding rod. In addition to tension, there is an advantage that can move the movable screen in the lateral direction smoothly.

Claims (1)
