TECHNICAL FIELD The present invention relates to a Roman shade.

[0002]

2. Description of the Related Art As a conventional Roman shade, a cloth having upper ends connected to head rails and weights attached to lower ends at predetermined intervals in the width direction is lifted by a lifting cord to form large folds at regular intervals. A type that can be tucked up while forming, or a type that attaches a weight bar over the entire length in the width direction instead of weights at the lower end of the cloth so that it can be tucked up while forming pleats at regular intervals There are things like. These Roman shades allow you to change the shape and size of the folds by changing the type of cloth and the connecting position of the lifting cord to the cloth, and use a translucent cloth for the view function. They have it, or use an opaque object to give it a shielding function.

[0003]

However, in the conventional Roman shade as described above, since there is only one shape when the cloth is tucked up, one Roman shade can produce various kinds of shapes. There is a problem that you can not. In order to have both the view function and the shielding function, the Roman shade made of a semi-transparent cloth and the Roman shade made of an opaque cloth are used.
There is a problem that it must be heavily used. Furthermore, in the conventional Roman shade, there is a problem that the light intensity can only be adjusted by tucking up the cloth, which makes it impossible to perform delicate light control.

As described above, Japanese Patent Application Laid-Open No. 7-39449 filed previously by the applicant of the present invention has a view function and a shielding function, which are combined without using two Roman shades together.
There is one shown in Japanese Patent Publication No. This shows:
One piece is semi-transparent, but becomes opaque when more than one piece is overlapped. The upper end of the cross is connected to the head rail, and a slack is formed at predetermined intervals in the vertical direction. The moving cord is connected to the upper end of the rear side of each slack, and the moving cord is moved up and down relatively to the support cord to raise and lower the connecting portion of the cloth moving cord. The slack is overlapped to shield it, and the view is obtained without overlapping it.

However, in the one disclosed in Japanese Patent Laid-Open No. 7-39449, it is possible to use a cloth having a pattern or color according to the taste so that one cloth has a view function and a shielding function. It is also impossible to change the appearance of the cloth even if the overlapping state of the cloth is changed. The present invention is to solve such a problem.

[0006]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is such that the upper end is connected to the head rail (10) and the lower end is the weight bar (14). A cord ring (16) is connected to a rear surface (12a) of a rear cross (12) connected to the vertical bar at a predetermined interval in the vertical direction.
4) is connected to one end of the lifting cord (18), and the other end of the lifting cord (18) is inserted into the head rail (10) through the cord ring (16) so that the lifting cord (18) can be lifted. On the front surface (12b) of the rear cloth (12), a plurality of front cloths (20, 40, 40) arranged over substantially the entire width direction of the rear cloth (12).
50, 60, 74, 80, 90, 94, 100) are respectively connected at predetermined intervals in the vertical direction of the rear cross (12), and each of the front cross (20, 40,
50, 60, 74, 80, 90, 94, 100) except for the portion connected to the rear cross (12),
One end side (22a) of the opening / closing cord (22) hanging from the head rail (10) is connected, and the other end (22b) of the opening / closing cord (22) can be moved up and down into the head rail (10). It is characterized by being introduced in.

Thus, in addition to the function of the conventional Roman shade, by operating the other end of the opening / closing cord to raise one end, the front cloth connected to the opening / closing cord is partially raised. Since the rear cross on the rear side can be exposed, the shape of the Roman shade can be changed.

Further, by using a translucent rear cloth, the view function can be obtained when the rear cloth is exposed. Further, the amount of light from the rear cross can be finely adjusted by the degree of rise of the front cross.

Further, since the front cloth and the rear cloth can be made of different cloths, it is possible to enjoy two kinds of patterns, colors and cloths according to tastes.

The invention according to claim 2 of the present invention is the invention according to claim 1, wherein the opening / closing cord (22) is used.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a Roman shade.

[0002]

2. Description of the Related Art As a conventional Roman shade, a cloth having upper ends connected to head rails and weights attached to lower ends at predetermined intervals in the width direction is lifted by a lifting cord to form large folds at regular intervals. A type that can be tucked up while forming, or a type that attaches a weight bar over the entire length in the width direction instead of weights at the lower end of the cloth so that it can be tucked up while forming pleats at regular intervals There are things like. These Roman shades allow you to change the shape and size of the folds by changing the type of cloth and the connecting position of the lifting cord to the cloth, and use a translucent cloth for the view function. They have it, or use an opaque object to give it a shielding function.

[0003]

However, in the conventional Roman shade as described above, since there is only one shape when the cloth is tucked up, one Roman shade can produce various kinds of shapes. There is a problem that you can not. In order to have both the view function and the shielding function, the Roman shade made of a semi-transparent cloth and the Roman shade made of an opaque cloth are used.
There is a problem that it must be heavily used. Furthermore, in the conventional Roman shade, there is a problem that the light intensity can only be adjusted by tucking up the cloth, which makes it impossible to perform delicate light control.

As described above, Japanese Patent Application Laid-Open No. 7-39449 filed previously by the applicant of the present invention is intended to have both a view function and a shielding function without using two Roman shades together.
There is one shown in Japanese Patent Publication No. This shows:
One piece is semi-transparent, but becomes opaque when more than one piece is overlapped. The upper end of the cross is connected to the head rail, and a slack is formed at predetermined intervals in the vertical direction. The moving cord is connected to the upper end of the rear side of each slack, and the moving cord is moved up and down relatively to the support cord to raise and lower the connecting portion of the cloth moving cord. The slack is overlapped to shield it, and the view is obtained without overlapping it.

However, in the one disclosed in Japanese Patent Laid-Open No. 7-39449, it is possible to use a cloth having a pattern or color according to the taste so that one cloth has a view function and a shielding function. It is also impossible to change the appearance of the cloth even if the overlapping state of the cloth is changed. The present invention is to solve such a problem.

[0006]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a rear side in which an upper end is connected to a head rail and a lower end is connected to a weight bar. A cord ring is connected to the rear surface of the cross at a predetermined interval in the vertical direction, one end of the lifting cord is connected to the weight bar, and the other end of the lifting cord is inserted through the cord ring to Introduced into the head rail, a plurality of front crosses are connected to the front surface of the rear cross at predetermined intervals in the vertical direction of the rear cross, and the front cross of each of the front crosses is connected to the front cross. One end side of an opening / closing cord that hangs up and down from the head rail is sequentially connected to appropriate positions other than the portion connected to the side cross.

Thus, in addition to the function of the conventional Roman shade, by operating the other end of the opening / closing cord to raise one end, the front cloth connected to the opening / closing cord is partially raised. Since the rear cross on the rear side can be exposed, the shape of the Roman shade can be changed.

Further, by using a translucent rear cloth, the view function can be obtained when the rear cloth is exposed. Further, the amount of light from the rear cross can be finely adjusted by the degree of rise of the front cross.

Further, since the front cloth and the rear cloth can be made of different cloths, it is possible to enjoy two kinds of patterns, colors and cloths according to tastes.

According to a second aspect of the present invention, in the first aspect of the invention, one or both of the other end of the lifting cord and the other end of the opening / closing cord are provided in the head rail. It is characterized in that it is led out of the head rail through a stopper capable of restraining movement of both or one of the lifting cord and the opening / closing cord.

Thus, by further pulling out the other end of the opening / closing cord to the outside of the head rail, one end side of the opening / closing cord is raised and each front cross is partially raised, and the rear cross on the rear side is pulled up. Can be exposed.

Further, by further pulling the other end of the elevating cord out of the head rail, one end of the elevating cord rises and the rear cross and the front cross rise.

According to a third aspect of the present invention, in the invention according to the first aspect, one or both of the other end of the lifting cord and the other end of the opening / closing cord are provided in the head rail. It is characterized in that it is wound and unwound around a drum that is rotationally driven by an external operation.

Thus, by winding the other end of the opening / closing cord around the drum, one end side of the opening / closing cord is raised and each front cross is partially raised, and the rear cross on the rear side is exposed. You can

By winding the other end of the elevating cord around the drum, one end of the elevating cord ascends and the rear cross and the front cross ascend.

According to a fourth aspect of the present invention, in the invention according to the first, second or third aspect, one end side of the opening / closing cord has a connecting portion between each of the front cross and the rear cross or It is characterized in that it is inserted into the connecting portion or the front cross in the vicinity thereof and is connected to the lower end of each front cross.

As a result, by raising one end of the opening / closing cord, the lower ends of the front crosses are raised, and the rear cross on the rear side can be exposed.

In the invention according to claim 5 of the present invention, in the invention according to claim 1, 2 or 3, the opening / closing cords are arranged apart from each other in front of the rear cross. The front cross is inserted at an intermediate position in the vertical direction of the front cross, and the inserted portions are connected to the front cross, respectively.

As a result, when one end of the opening / closing cord is raised, the midway position in the vertical direction of each front cross is raised, and the lower end of the front cross is raised accordingly. Can be exposed. Further, even when the front cross is closed, the lower end of the upper front cross vertically adjacent to each other and the upper end of the lower front cross are separated from each other in the front-rear direction, so a translucent rear cross is used. In this case, it is possible to indirectly enter light into the room from the separated portion.

In the invention according to claim 6 of the present invention, in the invention according to claim 1, 2, 3, 4 or 5, the lower end portion of each of the front crosses is provided with a total length in the width direction of the front cross. It is characterized in that a horizontal bar is attached across or partially.

When the horizontal bar is attached over the entire length of the lower end of the front cross in the width direction, when one end of the opening / closing cord is raised, the entire length of the lower end of the front cross is raised linearly. Can form regular folds on the cross,
In addition, when a horizontal bar is partially attached to the lower end of the front cross, the part where the horizontal bar is installed is raised linearly and the part where the horizontal bar is not installed is wavy. It is possible to form various shapes.

According to a seventh aspect of the present invention, in the first, second, third, fourth or fifth aspect of the invention, the front cross is provided at a lower end portion of each of the front cross and an intermediate position in the vertical direction. The horizontal bar is attached over the entire length in the width direction of the.

As a result, when one end side of the opening / closing cord is lifted and the front cross connected to the opening / closing cord is lifted, the horizontal bar attached in the vertical middle position of the front cross serves as a weight. Since it is folded so that it is located at the lower end, a sharp impression can be given.

In the invention according to claim 8 of the present invention, in the invention according to claim 1, 2, 3, 4, 5 or 6, each of the front side cloths is made of a material having elasticity, and the front side cloths are It is characterized in that an easily bendable portion that can be bent over the entire length in the width direction is formed at one or more positions in the vertical direction.

As a result, when one end side of the opening / closing cord is lifted and the front cross connected to the opening / closing cord is lifted, the front cross does not hang down due to the elastic material, so that it can be easily bent. Since it is bent, the aperture ratio between the vertically adjacent front crosses is increased and the degree of exposure of the rear crosses can be increased, as compared with the case where a flexible material is not used.

Further, the greater the number of easily bent portions formed on the front cross, the greater the number of bendable steps.
The exposure degree of the rear cross can be further increased.

According to a ninth aspect of the present invention, in the first, second, third, fourth, sixth, seventh or eighth aspect of the invention, a spacer is provided in front of each of the front crosses from the head rail. Characterized in that it is suspended, and the spacers are respectively connected to the horizontal bar portions attached to the middle positions in the vertical direction of the respective front crosses at positions spaced by a predetermined distance in the vertical direction. Is.

As a result, when one end side of the opening / closing cord is lifted and the front cross connected to the opening / closing cord is lifted, the horizontal bar portion attached to the middle position in the vertical direction of the front cross serves as the spacer. Since they are connected, the horizontal bar portion does not hang down, and only the lower end portion rises with the horizontal bar portion as a fulcrum. Therefore, when the horizontal bar portion is attached to the front side cross at a substantially vertical center position or more, the aperture ratio is increased as compared with the case where it is not connected to the spacer,
The degree of exposure of the rear cross can be increased.

Further, since the spacer is arranged apart from the rear cross, the front cross in the vertical direction projects forward and the front cross is formed in a triangular shape, so that the front cross has a three-dimensional shape. Can be changed.

The invention according to claim 10 of the present invention is
The invention according to claim 1, 2, 3, 4, 5, 6, 7, 8 or 9, wherein a balance is provided on a front surface side of each front cross from an upper end portion of the front cross to an intermediate position in the vertical direction. It is characterized by that.

In the invention according to claim 4 of the present invention, the lower ends of the front crosses are respectively raised by raising one end of the opening / closing cord, and the rear cross on the rear side is exposed. be able to.

Further, in the invention according to claim 5 of the present invention, by raising one end side of the opening / closing cord, the middle positions in the vertical direction of the front crosses are raised respectively, and the lower end of the front cross is accordingly raised. Therefore, the rear cross on the rear side can be exposed.

Even when the front cross is closed, the lower end of the upper front cross and the upper end of the lower front cross, which are vertically adjacent to each other, are separated from each other in the front-rear direction, and thus are translucent to the rear cross. When the above-mentioned one is used, light can be indirectly introduced into the room from the separated portion.

Further, in the invention according to claim 6 of the present invention, when a horizontal bar is attached over the entire length in the width direction of the lower end portion of the front cross, when one end side of the opening / closing cord is raised,
The entire length of the lower end portion of the front cloth can be linearly raised to form regular pleats on the front cloth. Also, when a horizontal bar is partially attached to the lower end of the front cross, various parts such as raising the part where the horizontal bar is provided linearly and wavy the part where the horizontal bar is not provided can be used. The shape can be configured.

Further, in the invention according to claim 7 of the present invention, when one end side of the opening / closing cord is lifted and the front cross connected to the opening / closing cord is lifted, an intermediate position in the vertical direction of the front cross is obtained. Since the horizontal bar attached to is used as a weight and is folded so that this part is located at the lower end, a sharp impression can be given.

Further, in the invention according to claim 8 of the present invention, when one end side of the opening / closing cord is lifted and the front cross connected to the opening / closing cord is lifted, the front cross is elastic. Because it can be bent at the easy-folding part without hanging down, the opening ratio between the front crosses that are vertically adjacent to each other is increased and the exposure degree of the rear cross is increased compared to the case where no elastic material is used. You can

Further, the greater the number of easily bent portions formed on the front cross, the greater the number of bendable steps.
It is possible to further increase the aperture ratio and further increase the exposure degree of the rear cross.

According to a ninth aspect of the present invention, when one end of the opening / closing cord is raised and the front cross connected to the opening / closing cord is raised, the front cross is positioned at an intermediate position in the vertical direction. Since the horizontal rod portion attached to the is connected to the spacer, the horizontal rod portion does not hang down, and only the lower end portion rises with the horizontal rod portion as a fulcrum. Therefore, when the horizontal bar portion is attached to the front cross at substantially the central position in the vertical direction or more, the aperture ratio is increased and the exposure degree of the rear cross can be increased as compared with the case where it is not connected to the spacer.

Further, since the spacers are arranged apart from the rear cross, the middle position in the vertical direction of the front cross projects forward and the front cross is formed in a triangular shape, so that the front cross has a three-dimensional shape. Can be changed.

According to a tenth aspect of the present invention, when one end side of the opening / closing cord is raised and the front cross connected to the opening / closing cord is raised to form a fold on the front cross. The front cross can be covered by balance.

In the invention according to claim 11 of the present invention, when one end side of the opening / closing cord is raised and the front cross connected to the opening / closing cord is raised, between the vertically adjacent insertion rings. Since the front cross crosses upward from the lowermost insertion ring to the upper insertion ring while forming a fold on the front cross, the front cross is compressed vertically without forming a large fold. Therefore, the aperture ratio between the front crosses that are vertically adjacent to each other increases, and the exposure degree of the rear cross can be increased.
