Description

Double Roll Shade Blinds {DOUBLE ROLL SHADE BLIND}

The present invention relates to a double roll shade blind, and more particularly, a double roll shade blind that can selectively change light and shade by opening and closing the light blocking paper in conjunction with the roll in a state in which the blind is unrolled from a roll, that is, in a light blocking state. is about

In general, blinds are mainly installed on windows of buildings to block (block) or inflow (light) sunlight, and are divided into various types according to their purpose or place of use.

Such blinds have a simpler appearance than curtains, so the demand for them is gradually increasing.

In particular, the double roll shade blind is a blind that can be switched between the light-lighting state and the light-shielding state by manipulating the roll in the state in which the blind is lowered, that is, in the state of blocking light.

The conventional double roll shade blind arranges a number of lateral shading sheets up and down on the front surface of the base mesh through integral weaving, and the upper connection part of each shading paper is connected and fixed to the base mesh paper, and the lower side of the shading paper is the mesh paper In the lower connection part of the shade paper, the opening and closing chambers spaced apart from side to side constitute a three-dimensional curtain paper that is connected and fixed in an integral weave. The lower through-hole is formed, and the opening/closing room, which is connected and fixed to the lower connection of the shade paper, has a thickness of 200 to 3000 denier, is connected to the lower connection of the shade paper, is fixed, is exposed to the front of the shade, and the lower through hole is freely opened. It passes through and enters the back of the awning, climbs on the back of the awning, passes freely through the upper through-hole, is exposed to the front, and then forms a three-dimensional curtain paper formed by repeating the configuration of being connected and fixed to the lower connection of the awning on the upper side. , The three-dimensional curtain paper is coupled and fixed in one transverse slit coupling groove of the roll shaft rod that can pivot between the brackets on both sides of the frame, but the base mesh of the three-dimensional curtain paper is the rear side of the roll shaft rod, and the three-dimensional curtain paper is fitted and fixed in the horizontal slit coupling groove, and the three-dimensional curtain paper and the shading paper The opening/closing vertical chamber is made to be fixed to the front side of the roll shaft rod and fitted into the horizontal slit coupling groove.

The double roll shade blind described above is disclosed in Korean Patent Publication No. 10-0988589.

However, in the double roll shade blind as above, since the shading paper (shading paper) is made of one layer of fabric, the shading paper is adjacent to the mesh and forms a flat surface in the shading state. For this reason, there is a problem in that external noise is hardly filtered and transmitted to the inside of the window.

And since the shading paper is made of a single layer of fabric, and heat transfer is relatively good compared to air, there is a problem in that the heat inside or outside is easily transferred to the outside or the inside through the blind in the shading state.

The present invention has been devised to solve the above problems, and an object to be solved in the present invention is to provide a double roll shade blind capable of improving sound insulation and heat insulation effects in a light-shielding state.

A double roll shade blind according to the present invention for solving the above problems, a roll having a cylindrical structure provided with a groove; a mesh having an upper end fixed to the groove; a light-shielding paper comprising a first edge fixed to the mesh, a second edge provided parallel to the first edge, and a sound insulation and insulating member formed between the first edge and the second edge; Its technical feature is that the upper end is connected to the roll, and the lower end consists of a light-shielding paper folding line fixed to the second edge.

The double roll shade blind according to the present invention is provided with a sound insulation insulation member between the first edge and the second edge of the light blocking paper, so that the sound insulation insulation member suppresses the transmission of sound and at the same time suppresses heat transfer in the light blocking state. By doing so, there is an advantage in that the sound insulation and heat insulation effect can be increased, and thus the usability and functionality of the blind can be increased.

The roll 20 having a cylindrical structure is rotatably installed inside the rail bar 10 , and the roll 20 is provided with a groove 21 . The upper end of the mesh paper 30 is fixed to the groove 21 , and the upper end of the light-shielding paper folding line 50 is directly fixed or indirectly fixed through the first auxiliary light-shielding paper 40 ′. The mesh paper 30, the light blocking paper 40 fixed to the mesh paper 30 (hereinafter, in the present invention, the 'mesh and light blocking paper combination' is referred to as 'blind paper') and the light blocking paper folding line 50 are shown in Fig. It is wound on the roll 20 as shown in 4, or is unrolled from the roll 20 as shown in FIG. 2 and hung on the window. The roll 20 is rotated by the roll operation line 22 shown in FIG. 1 .

The mesh 30 is made of a light-transmitting material, and the upper end is fixed to the groove 21 of the roll 20, and in the light-shielding state as shown in FIG. 5 (a), the roll 20 is wound in a counterclockwise direction. is located In addition, the mesh 30 may be laminated and wound on the roll 20 as shown in FIG. 4 because it is flexible.

The light blocking paper 40 includes a first edge 41 fixed to the mesh paper 30 , a second edge 42 provided parallel to the first edge 41 , a first edge 41 and a second edge ( 42) is composed of a sound insulation and insulating member 43 formed between. The light blocking paper 40 is made of a flexible material. The first edge 41 has a certain length, and is fixed to the mesh 30 by weaving or by using an adhesive. The second edge 42 has a predetermined length, and is provided in parallel to the first edge 41 at a distance along the longitudinal direction. In addition, the light-shielding paper folding line 50 is fixed to the second edge 42 .

In the state diagram of the light-shielding state of the light-shielding paper 40 in FIG. By moving toward (41), it is switched to a lighted state. In addition, the second edge 42 moves in a direction away from the first edge 41 in the light-blocking state, thereby switching to the light-shielding state.

The sound insulation and heat insulating member 43 increases the sound insulation and heat insulation effect by having a function of suppressing sound transmission and heat transfer in a light blocking state, that is, in a state in which the light blocking paper 40 covers the mesh paper 30 .

That is, the sound insulation and heat insulating member 43 includes a first member 43a connected between the first edge 41 and the second edge 42 , and a first edge 41 and a first edge 41 to face the first member 43a and It consists of a second member 43b connected between the second edge 42 and an air layer 43c formed between the first member 43a and the second member 43b, and the air layer 43c in a light-shielding state. It has the function of suppressing the transmission of sound and the transmission of heat.

In addition, as shown in FIG. 3 , the air layer 43c is preferably formed in plurality in the longitudinal direction of the light blocking paper 40 , and the light blocking paper folding line 50 passes through the central portion of the air layer 43c . are doing A plurality of air layers 43c are formed by fixing the first member 43a and the second member 43b to a predetermined width in the longitudinal direction with weaving or an adhesive along the width direction of the light-shielding paper. In this case, the light-shielding paper folding line 50 may pass through the fixing portions of the first member 43a and the second member 43b, and the portion through which the light-shielding paper folding line 50 passes is the first member 43a. ) and the second member 43b may not be fixed.

In the present invention having the above air layer 43c, the air layer 43c has a function of suppressing sound transmission and heat transfer in the light-shielding state, and the effect of increasing the light-lighting range can be expected in the light-shielding state.

The increase in the mining range is as follows. In the state diagram of FIG. 5 (b) of the lighting state, the light-shielding paper fold line 50 passes through the central portion of each air layer 43c, and each air layer 43c is connected to each other by the light-shielding paper fold line 50. It is folded while closely adhering, and since the closely adhered air layer 43c maintains an almost perpendicular state with respect to the longitudinal direction of the light-shielding paper, the amount of drooping down of the light-shielding paper made of a flexible material is reduced, thereby increasing the light coverage. That is, the present invention maintains a state in which the fixing parts of the first member 43a and the second member 43b of each air layer 43c folded in close contact with each other in the lighted state are in contact with each other, and the air layer 43c located on the upper part ) of the folded portion is subjected to a force acting upward by the folded portion of the air layer 43c located below. Accordingly, each of the folded air layers 43c is maintained at a substantially right angle with respect to the longitudinal direction, so that sagging hardly occurs.

On the other hand, in the inside of the air layer (43c), if necessary, it is possible to additionally form a soft auxiliary sound insulation insulating material (not shown) that can be linked to the shape change of the air layer (43c). The auxiliary soundproofing and insulating material has the effect of increasing the soundproofing and insulating function of the air layer 43c in the light-shielding state.

In addition, as shown in FIG. 3 , the friction reducing member 44 may be additionally connected between the first edge 41 and the air layer 43c. The friction reducing member 44 has a function of minimizing noise due to friction generated between the light blocking paper 40 and the mesh paper 30 in the process of switching from the light blocking state to the lighting state or vice versa. That is, in the light blocking state, the light blocking paper fold line 50 is in contact with the friction reducing member 44 and the first edge 41 . The process of switching from the light-shielding state to the light-lighting state is as shown in Fig. 5, but in Fig. 5 (a), according to the counterclockwise rotation of the roll 20, the light-shielding paper folding line 50 ( a) is an embodiment in which the folding line of the light-shielding paper is fixed to the first auxiliary light-shielding paper) also moves upward according to the rotation of the roll 20, and this moves the second edge 42 of the light-shielding paper 40 to the roll ( 20), each air layer 43c is folded at a right angle with respect to the longitudinal direction, and the connection portion of the friction reducing member 44 connected to the air layer 43c is the first edge 41. It is rotated toward the roll 20 around the end of the. Accordingly, the light-shielding paper 40 is spaced apart from the mesh paper 30 by a certain distance during the transition from the light-shielding state to the light-lighting state, thereby reducing the generation of noise due to contact with the mesh paper 30 and changing the shape of the air layer. to keep

On the other hand, when the height of the friction reducing member 44 is approximately 1/2 of the height of the air layer 43c, the separation distance between the light-shielding paper folding line 50 and the mesh paper 30 in the lighted state is the air layer 43c. It can be kept constant at the folded height (approximately 1/2 the height of the air layer).

A plurality of light-shielding paper 40 may be continuously formed along the longitudinal direction of the mesh paper 30 . In this case, the light-shielding paper folding line 50 is the first edge 41 and the friction reducing member 44 of the light-shielding paper 40 located below from the second edge 42 of the light-shielding paper 40 located above. It is formed to pass through the air layer 43c. By forming a plurality of light-shielding papers 40 , the blind papers can be matched according to the window height without changing the length of the unit light-shielding papers 40 .

The light-shielding paper folding line 50 has an upper end connected to the roll 20 , and a lower end fixed to the second edge 42 . The light-shielding paper folding line 50 is the second of the light-shielding paper 40 fixed to the light-shielding paper folding line 50 in conjunction with the counterclockwise rotation of the roll 20 in the light-shielding state of FIG. When the edge 42 moves in the direction of the first edge 41, it enters the light state, and when the roll 20 is rotated clockwise in FIG. 5(b), the second edge ( As the 42 moves in the direction away from the first edge 42 , the light-shielding state is obtained.

The upper end of the light-shielding paper folding line 50 is connected to the roll 20, and this connection includes a direct connection and an indirect connection. That is, in the direct connection, the upper end of the light-shielding paper folding line 50 is directly fixed to the groove 21 of the roll 20, and in the indirect connection, the upper end of the first auxiliary light-shielding paper 40 ′ is fixed as shown in FIG. 2 . It is fixed to the groove 21 of the roll 20 and the upper end of the light-shielding paper folding line 50 is fixed to the lower end of the first auxiliary light-shielding paper 40'.
