Description

DOUBLE ROMAN SHADE BLIND}

The present invention relates to a double Roman shade blind, and more specifically, to a double Roman shade blind that can selectively change lighting and shading by opening and closing the light shield in the blind lowered state, that is, in the light blocking state.

In general, blinds are mainly installed on windows of buildings to block (shade) or bring in (light) sunlight, and are classified into various types depending on the purpose of use or location of use.

These blinds have a simpler appearance than curtains, so their demand is gradually increasing.

In particular, the double Roman shade blind is a blind that can be switched from the light-blocking state to the light-blocking state by manipulating the control string in the blind lowered state, that is, the light-blocking state or the light-blocking state.

A conventional double Roman shade blind is a blind that includes an auxiliary curtain, a rail bar; It includes a main lifting device and an auxiliary lifting device installed on the rail bar and capable of being artificially operated; The main lifting device includes some main cords and is installed at the lower part of the rail bar to control the lifting and lowering of the main cords; The auxiliary lifting device includes some sub-cords and is installed at the lower part of the rail bar to control the lifting and lowering of the sub-cords; It includes one badge, where the upper end of the badge is connected to the rail bar and the lower end of the main cord is connected to the lower end of the badge to control the altitude of the badge when the main elevating device operates; comprising at least one piece of decorative fabric, wherein the decorative fabric is installed on the drapery, the upper end is connected to the drapery, and the lower end is freely movable; The sub-cord is connected to the bottom of the insignia and can control opening and closing of the bottom of the decorative cloth in the vertical direction when controlling the auxiliary lifting device.

The double Roman shade blind described above is disclosed in Republic of China Patent Publication No. 445827.

However, since the double Roman shade blind like the one above is made up of a single layer of decorative fabric (shading paper), the decorative fabric forms a plane adjacent to the drapery (mesh paper) in the light-shading state. Because of this, there is a problem that external noise is transmitted to the inside of the window without being filtered out.

Additionally, decorative cloth is made up of a single layer of fabric, and because it conducts heat relatively well compared to air, there is a problem in that heat from the inside or outside is easily transferred to the outside or inside through the blind in a shaded state.

The present invention was created to solve the above problems, and the problem to be solved by the present invention is to provide a double Roman shade blind that can improve soundproofing and thermal insulation effects in a light blocking state.

The double Roman shade blind according to the present invention to solve the above problems includes a rail bar; A plurality of first winders installed on the rail bar, a second winder installed to be relatively movable with respect to the first winder, a connecting rod, and a winder that operates the plurality of first winders and the second winder through the connecting rod. An elevator section consisting of a odor control line; A mesh whose upper end is fixed to one side of the rail bar; a plurality of light-shielding sheets composed of a first edge fixed to the mesh, a second edge provided parallel to the first edge, and a soundproofing and insulating member formed between the first edge and the second edge; a light-shielding paper folding line whose upper end is fixed to the first winder and whose lower end is fixed to the second edge; A weight bar fixed to the bottom of the mesh; Its technical feature is that the upper end is fixed to the second winder, and the lower end is made of a lifting rope fixed to the weight bar.

The double Roman shade blind according to the present invention is provided with a soundproofing insulating member between the first edge and the second edge of the light blocking paper, and in the light blocking state, the soundproofing and insulating member functions to suppress the transmission of sound and at the same time suppress heat transfer. By doing so, there is an advantage of increasing the soundproofing and thermal insulation effects, and thus the usability and functionality of the blind can be improved.

Below, the double Roman shade blind according to the present invention will be described in detail through the attached drawings.

As shown in Figures 1 to 5, the double Roman shade blind according to the present invention includes a rail bar (10); A plurality of first winders 21 installed on the rail bar 10, a second winder 22 installed to be relatively movable with respect to the first winder 21, a connecting rod 23, and a connecting rod 23 ) an elevating unit (20) consisting of a winder operating line (24) that operates a plurality of first winders (21) and second winders (22) through ; A mesh (30) whose upper end is fixed to one side of the rail bar (10); A first edge 41 fixed to the mesh 30, a second edge 42 provided parallel to the first edge, and a soundproofing and insulating member formed between the first edge 41 and the second edge 42 ( A plurality of shading sheets (40) consisting of 43); A light-shielding paper folding line (50) whose upper end is fixed to the first winder (21) and whose lower end is fixed to the second edge (42); A weight bar (60) fixed to the bottom of the mesh; The upper end is fixed to the second winder (22), and the lower end includes a lifting rope (70) fixed to the weight bar (60).

The rail bar 10 and the lifting unit 20 are known configurations. As shown in FIG. 4, a plurality of first winders 21 and second winders 22 are installed inside the rail bar 10, and these plurality of first winders 21 and second winders (22) is connected by a connecting rod (23), and the second winder (22) is installed to be relatively movable with respect to the first winder (21). The connecting rod 23 is operated by the winder operating line 24.

However, the winder indicated by code 132 in Figure 15 of Republic of China Patent Publication No. 445827, which is a prior art, corresponds to the first winder 21 of the present invention, and the winder indicated by code 126 corresponds to the second winder 22 of the present invention. Correspondingly, these winders are each operated by different lifting units (symbols 125 and 130). Meanwhile, in Figure 8 of Registered Patent No. 10-1527414, which is another prior art, the angle adjustment member indicated by symbol 29 corresponds to the first winder 21 of the present invention, and the drum indicated by symbol 30 corresponds to the second winder of the present invention ( Corresponding to 22), the drum is installed to be relatively movable with respect to the angle adjustment member, so it can be seen that it has the same configuration as the present invention. Therefore, it can be seen that no matter which of the above prior technologies is adopted, it has substantially the same function as the present invention.

The mesh 30 is made of a light-transmitting material, and its upper end is fixed to one side of the rail bar 10. In addition, the mesh 30 is flexible and can be stacked as shown in (a) of FIG. 5.

The light-shielding 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) It consists of a soundproofing and insulating member 43 formed between the two, and is formed in plural numbers in the longitudinal direction of the mesh paper 30 (hereinafter, in the present invention, the 'combination of mesh paper and light-shielding paper' is referred to as 'blind paper'). . 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 paper 30 by weaving or using adhesive. The second edge 42 has a certain length and is provided parallel to the first edge 41 at a distance along the longitudinal direction. Additionally, a light-shielding paper folding line 50 is fixed to the second edge 42.

The light-shielding paper 40 moves in conjunction with the rotation of the first winder 21 in the light-shielding state so that the second edge 42 fixed to the light-shielding paper folding line 50 moves toward the first edge 41. converted to mining mode. Additionally, the light-blocking state is switched from the light-emitting state to the light-blocking state as the second edge 42 moves in a direction away from the first edge 41.

The soundproofing and insulating member 43 has a function of suppressing sound and heat transfer in a light-shielding state, that is, in a state in which the light-shielding paper 40 covers the mesh paper 30, thereby increasing the soundproofing and thermal insulation effects.

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

In addition, as shown in FIG. 3, the air layer 43c is preferably formed in plural pieces in the longitudinal direction of the light-shielding paper 40, and the light-shielding paper fold line 50 penetrates the central portion of the air layer 43c. I'm doing it. The formation of a plurality of air layers 43c is performed by fixing the first member 43a and the second member 43b to a certain width in the longitudinal direction with weaving or adhesive along the width direction of the light-shielding paper. In this case, the light-shielding paper folding line 50 can pass through the fixing parts of the first member 43a and the second member 43b, and the area 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 provided with the air layer 43c as described above, the air layer 43c has the function of suppressing sound and heat transfer in a light-shielding state, and can be expected to have the effect of increasing the lighting range in a daylighting state.

The increase in mining area is based on the following. In the lighting condition of Figure 5 (b), the light-shielding paper folding line 50 passes through the central portion of each air layer 43c, and each air layer 43c is in close contact with each other by the light-shielding paper folding line 50. As it folds, the air layer 43c in close contact maintains an almost right angle to the longitudinal direction of the light-shielding paper, so the amount of downward sagging of the light-shielding paper made of flexible material is reduced, thereby increasing the lighting range. That is, in the present invention, the fixing portions of the first member 43a and the second member 43b of each air layer 43c that are folded in close contact with each other in a daylighting state are maintained in contact with each other, and the air layer 43c located at the upper portion is maintained in contact with each other. ) The folded portion receives an upward force from the folded portion of the air layer 43c located at the bottom. Accordingly, each folded air layer 43c maintains an almost right angle to the longitudinal direction, so sagging hardly occurs.

Meanwhile, a soft auxiliary soundproofing insulator (not shown) that can be adjusted to change the shape of the air layer 43c may be additionally formed inside the air layer 43c, if necessary. The auxiliary soundproofing insulating material has the effect of increasing the soundproofing and thermal insulation functions of the air layer 43c in a light-shielding state.

Additionally, as shown in FIG. 3, the friction reduction member 44 may be additionally connected between the first edge 41 and the air layer 43c. The friction reduction member 44 minimizes friction and noise by creating a gap between the shading paper 40 and the shading paper folding line 50 and the mesh paper 30 during the process of switching from the shading state to the shading state or vice versa. and has the function of causing the air layer 43c to be folded at a right angle to the longitudinal direction. That is, in the light blocking state, the light blocking paper folding line 50 is in contact with the friction reduction member 44 and the first edge 41. The process of switching from the light-shielding state to the mining state is as shown in Figure 5. In Figure 5(c), as the first winder 21 rotates, the light-shielding paper folding line 50 is moved to the first winder ( 21), it moves upward, and this acts as a force to pull the second edge 42 of the light-shielding paper 40 upward, and each air layer 43c is folded at a right angle to the longitudinal direction. , the connection portion of the friction reduction member 44 connected to the air layer 43c rotates toward the first winder 21 with the end of the first edge 41 as the center. Accordingly, the shading paper 40 is spaced a certain distance away from the mesh paper 30 during the transition from the shading state to the daylighting state, thereby reducing the generation of noise due to contact with the mesh paper 30 and the air layer 43c. ) to maintain its shape.

On the other hand, when the height of the friction reducing member 44 is set to 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 daylight condition is the air layer 43c. It is possible to maintain a constant folded height (approximately 1/2 of the height of the air layer).

A plurality of light-shielding sheets 40 are formed continuously along the longitudinal direction of the mesh sheet 30. In this case, the light-shielding paper folding line 50 is formed from the second edge 42 of the light-shielding paper 40 located above, the first edge 41 of the light-shielding paper 40 located below, and the friction reduction member 44. It is formed to pass through the air layer 43c.

The upper end of the light-shielding paper folding line 50 is fixed to the first winder 21, and the lower end is fixed to the second edge 42. The light-shielding paper folding line 50 is linked to the rotation of the first winder 21 in a light-shielding state, so that the second edge 42 of the light-shielding paper 40 fixed to the light-shielding paper folding line 50 is the first edge. By moving in the direction of (41), the mining state is entered, and in the mining state, the second edge 42 of the light-shielding paper 40 is aligned with the first edge 42 in conjunction with the opposite rotation of the first winder 21. By moving in a direction away from , the light is blocked.

In the embodiment of the present invention shown in Figure 1, four light-shielding paper folding lines 50 are installed. If a plurality of light-shielding paper folding lines 50 are installed at equal intervals, the light-shielding paper 40 can be smoothly moved across the width direction of the blind paper.

The weight bar 60 is fixed to the bottom of the mesh paper 30. Additionally, the weight bar 60 may be fixed to the second edge 42 of the light blocking portion located at the lowest part of the light blocking paper 40. The weight bar 60 has a certain weight and stably supports the blind including the mesh 30 in a light-shielding state, and is formed in a structure that can stably support the stacked blind when stacking the blind. desirable. Since the weight bar 60 adopts known technology, its detailed description is omitted.

The upper end of the lifting rope 70 is fixed to the second winder 22, and the lower end is fixed to the weight bar 60. Specifically, the lifting line 70 passes between the mesh paper 30 and the light blocking paper 40, and the first edge 41 of the light blocking paper 40 fixed to the mesh paper 30 is It passes over the edge 41 and penetrates the light-shielding paper 40.

Figure 5(a) shows a state in which blind sheets are stacked. In this state, the lifting rope 70 is wound around the second winder 22, and the weight bar 60 is located close to the rail bar 10.

In a state where the blind sheets are stacked, when the winder operating rope 24 is operated in the direction in which the lifting rope 70 wound around the second winder 22 is released, the lifting rope 70 is released and the weight bar 60 is lifted. Move in a direction away from the rail bar (10). In this state, the first winder 21 rotates in the same direction as the second winder 22, and if the light-shielding paper folding line 50 fixed to the first winder 21 is set to be released, While the weight bar 60 moves away from the rail bar 10, the blind paper that is not laminated switches from the lighting state to the light blocking state.

Figure 5(d) shows the lighting condition in a state where part of the blind paper is laminated. A part of the mesh paper 30 is laminated by the weight bar 60, and a part of the light-shielding paper 40 is also laminated by the weight bar 60 in the opposite direction to the mesh paper 30. On the other hand, since the light-shielding paper 40 that is not laminated is in a state where it can be manipulated, when the winder operation line 24 is operated, the light-shielding state is switched from the light-shielding state, or the light-shielding state is converted into the light-shielding state. That is, according to the present invention, it is possible to switch from a light-blocking state to a light-blocking state or from a light-blocking state to a light-blocking state even when a portion of the blind paper is laminated.

In the embodiment of the present invention shown in Figure 1, four lifting ropes 70 are installed. When a plurality of lifting ropes 70 are installed, the weight bar 60 can be moved up and down smoothly.

The usage status of the double Roman shade blind described above can be briefly explained as follows.

First, (a) in Figure 5 shows a state in which blind paper is stacked on the weight bar 60, and the blind paper is located directly below the rail bar 10. In this state, when the user operates the winder operation line 24, the weight bar 60 moves downward, while the unlaminated light-shielding paper 40 is converted to a light-shielding state, and the lifting line 70 is maximised. In the unlocked state, that is, when the weight bar 60 is located at the lowest position, it enters the light blocking state shown in (c) of FIG. 5.

When the winder operation line 24 is operated in the light-shielding state, the second edge 42 of the light-shielding paper 40 moves in the direction of the first edge 41 of the light-shielding paper, resulting in the light-shielding state of Figure 5 (b). .

When the winder operating line 24 is operated in a light blocking state, the weight bar 60 moves in the direction of the rail bar 10, and the blind paper is in a partially laminated state as shown in (d) of FIG. 5. On the other hand, if the winder operating line 24 is operated in a different direction during the partial lamination state, the portion of the blind paper that is not in the lamination state is in a light blocking state.

In this way, in the present invention, when the winder operating line 24 is operated in the opposite direction while the weight bar 60 is moving downward in the blind paper laminated state, the weight bar 60 stops moving downward and moves upward at the same time. By doing this, the blind paper part that is not in the laminated state can be converted from a light-blocking state to a light-emitting state. In addition, when the weight bar 60 moves to the maximum distance from the rail bar 10, all of the light-shielding paper 40 is in a light-shielding state, and in this light-shielding state, the winder operation line 24 is operated in the opposite direction. If you do this, you can switch to the mining state, and if you continue to operate the winder operation line (24), you can switch to the blind paper stacking state. In addition, if the winder operating line 24 is operated in the opposite direction during lamination of blind paper, lamination is temporarily stopped and the portion of blind paper that is not laminated is converted to a light blocking state.
