AI Technical Summary
In rooms with limited budget, such as rental properties, hanging two curtain rails for different light-blocking and translucent curtains is impractical, necessitating the use of only one curtain rail, which limits the ability to adjust light levels effectively.
A curtain design with alternating high and low translucency regions, allowing a single curtain rail to support two curtains, where one curtain is shorter by one stripe at one end, enabling easy switching between translucent and non-translucent states by alternating their positions on the rail.
This design allows for seamless adjustment of light transmission by alternating the curtains on a single rail, providing flexibility in light control without the need for multiple rails, ensuring easy transitions between transparent and opaque states.

Abstract
Description
[Technical field]
[0001] The present invention relates to a curtain, and more particularly to a curtain set that can be used as both a light-transmitting curtain and a light-blocking curtain. [Background technology]
[0002] There are various functions that are required of curtains, but one of the most important is the ability to adjust the amount of light that is blocked. For this reason, blackout curtains that maximize this function and highly translucent curtains that only partially fulfill this function are used.
[0003] The optimal way to let in light for a room or space, in other words the degree of light blocking, changes depending on the time, the room's usage, and the season. For this reason, it has been common to hang two curtains, one with high light blocking properties and one with low light blocking properties, on a window in order to provide curtains with multiple light blocking properties. Summary of the Invention [Problem to be solved by the invention]
[0004] A curtain rail is needed to hang curtains. If you want to hang two curtains, you will inevitably need two curtain rails, but in rooms where costs are a strict constraint, such as rental properties, there may only be one curtain rail, and in that case you could only use either drape curtains or lace curtains. [Means for solving the problem]
[0005] Therefore, in the present invention, A curtain in which a first region having high light transmittance and a second region having low light transmittance are arranged to form vertical stripes, A first curtain having a left end and a right end that are the second region and a hole for inserting a curtain hook formed on the back surface thereof; The curtain set is composed of a second curtain, the left end of which is a first region and the right end of which is a second region, or the right end of which is the first region and the left end of which is a second region, the back of which is formed with a hole for inserting a curtain hook, and the second curtain is shorter in the horizontal direction by one stripe than the first curtain. Effect of the Invention
[0006] The curtain hook inserted into the hole at the left end of the first curtain is fixed to the runner at the left end of the curtain rail, then the curtain hook inserted into the hole at the left end of the second curtain is fixed to the second runner from the left end of the curtain rail, and subsequently the first and second curtains are alternately fixed to the runners.This results in high light transmittance in a first state where the first areas of the first curtain and the second curtain overlap, and low light transmittance in a second state where the second area of the first curtain and the first area of the second curtain overlap.
[0007] Furthermore, the runner prevents the first and second curtains from shifting too far to the left or right, making it easy to transition from the first state to the second state, and conversely, from the second state to the first state. [Brief description of the drawings]
[0008] [Figure 1] FIG. 1 is a diagram showing a curtain set according to the present invention in a first state; [Diagram 2] FIG. 2 is a view showing the curtain set of the present invention in a second state; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] FIG. 1 shows a curtain set of the present invention, which is composed of a first curtain 1 and a second curtain 2. As shown in FIG.
[0010] The first curtain 1 is composed of a first region 3 and a second region 4, and as shown in Figure 1, the first region 3 and the second region 4 alternate in a roughly whale-like pattern, forming an overall vertical striped pattern. The width of one first region 3 and the width of one second region 4 are the same. However, both the left and right ends of the first curtain are in the second region 4. The first region 3 has high light transmittance, while the second region 4 has low light transmittance.
[0011] The rest of the first curtain 1 is similar to commonly available curtains. The upper part of the curtain is made of interlining, and holes are formed on the back side. The curtain is fixed to the window by inserting a curtain hook into the hole and hanging the hook from a curtain runner on a curtain rail.
[0012] As a specific method for changing the level of light transmittance, all of the many methods that have been developed in the curtain industry so far can be adopted. For example, lace fabric may be used in the first area 3, and drapery fabric may be used in the second area 4. The same thread may be used in the first area 3 and the second area 4, but the density may be changed by devising a sewing technique to create a difference in light transmittance. The latter is more suitable from the viewpoint of a unified look for the entire curtain.
[0013] There are two types of second curtains 2: a second curtain 2A for hanging on the left side of the window, and a second curtain 2B for hanging on the right side of the window.
[0014] The second curtain 2A, like the first curtain 1, is composed of a first region 3 and a second region 4, and as shown in FIG. 1, the first region 3 and the second region 4 alternate in a roughly whale-like shape, forming an overall vertical striped pattern. The width of one first region 3 and the width of one second region 4 are the same. Like the first curtain, the left end is the second region 4, followed by the first region 3, and then the second region 4, forming a vertical striped pattern like the first region, but the right end is the first region 3. Compared to the first curtain 1, there is one second region 4 less at the right end, making it shorter in the width direction by that amount.
[0015] The second curtain 2B, like the first curtain 1, is composed of a first region 3 and a second region 4, and the first region 3 and the second region 4 alternate in a roughly whale-like pattern, forming an overall vertical striped pattern. The width of one first region 3 and the width of one second region 4 are the same. Like the first curtain, the right end is the second region 4, followed by the first region 3, and then the second region 4, but the left end is the first region 3. Compared to the first curtain 1, there is one less second region 4 at the left end, making it shorter in the width direction by that amount.
[0016] The method of using the curtain set of the present invention consisting of the first curtain 1 and the second curtain 2 is as follows: first, insert the curtain hook into the hole at the left end of the first curtain and secure it to the curtain runner at the left end of the curtain rail, or to a fixture at the left end of the curtain rail.
[0017] Next, the curtain hook inserted into the hole at the left end of the second curtain 2A is fixed to the curtain runner next to the left end of the curtain rail. This curtain runner is connected to the same curtain rail as the curtain liner that hung the first curtain.
[0018] Next, the curtain hook inserted into the second hole from the left of the first curtain is fixed to the curtain liner next to the curtain liner from which the second curtain 2A is hung. This process is then repeated to fix the first curtain 1 and the second curtain 2A to the curtain liner.
[0019] As shown in Figure 1, when the first area 3 of the first curtain 1 overlaps with the first area 3 of the second curtain 2A, and the second area 4 of the first curtain 1 overlaps with the second area 4 of the second curtain 2A, light is guided into the room from the first area 3.
[0020] From this state, only the second curtain 2A is moved to the right, so that the first area 3 of the first curtain 1 overlaps the second area 4 of the second curtain 2A, and the second area 4 of the first curtain 1 overlaps the first area 3 of the second curtain 2A, as shown in Figure 2.
[0021] Then, the light guided from the first region 3 of the first curtain 1 is blocked by the second region 4 of the second curtain 2A. The part of the first region 3 of the second curtain 2 is also blocked by the second region 4 of the first curtain 1 because it overlaps with the first region 3. As a result, the first curtain 1 and the second curtain 2 create a state in which the light transmittance is reduced over the entire surface.
[0022] The first curtain 1 and the second curtain 2 are alternately fixed to the curtain liner by curtain hooks. Therefore, even if the second curtain is moved left and right while the first curtain is fixed, the curtain hooks that fix the curtain are fixed to the curtain liner, so the second curtain does not move left and right beyond the curtain liner. In other words, the second curtain 2 does not move more than the width of one of the first area 3 or the second area 4. Therefore, the translucent state and the non-translucent state can be easily switched by roughly pulling the second curtain.
[0023] When using a large window or when curtains are hung from both sides of the window for design reasons, the first curtain 1 and the second curtain 2A can be used on the left side of the window, and the first curtain 1 and the second curtain 2B can be used on the right side of the window.
[0024] The method of using the second curtain 2B is to first fix a curtain hook inserted into a hole at the right end of the first curtain to a curtain runner at the right end of the curtain rail or to a fixture at the right end of the curtain rail.
[0025] Next, the curtain hook inserted into the hole at the right end of the second curtain 2B is fixed to the curtain runner one space away from the right end of the curtain rail.
[0026] Next, the curtain hook inserted into the second hole from the right of the first curtain 1 is fixed to the curtain liner next to the curtain liner from which the second curtain 2B is hung. This process is then repeated to fix the first curtain 1 and the second curtain 2B to the curtain liner.
[0027] The method of separating the first curtain 1 and the second curtain 2B into a light-transmitting state and a light-non-transmitting state is similar to that of the first curtain 1 and the second curtain 2A.
