DETAILED DESCRIPTION OF THE INVENTION

[0009] The following describes embodiments of the present invention. The various features shown in the following embodiments can be combined with each other. Furthermore, each feature can be an invention independently.

[0010] 1. Overall configuration of the shading device 100 As shown in Figures 1A to 2, a shading device 100 according to one embodiment of the present invention comprises a hanger rail 1, a tilt axis 2, a tilt operation rod 3, an operation cord 4, a runner 5, and a shading material 6 consisting of a plurality of shading material units 6U.

[0011] As shown in Fig. 1A, the clothes hanger rail 1 is configured in a case shape and is installed, for example, on the wall, ceiling, or window frame of a building. A tilt shaft 2 and multiple runners 5 are housed inside the clothes hanger rail 1. Multiple runners 5 are attached to the tilt shaft 2. When the tilt shaft 2 rotates, each runner 5 rotates.

[0012] As shown in Fig. 1A, a tilt operation rod 3 and an operation cord 4 are arranged on the left side, which is one end in the width direction of the hanger rail 1. The tilt operation rod 3 is configured to rotate the tilt shaft 2, and by operating the tilt operation rod 3 to rotate the tilt shaft 2, the shaft portion 5c of each runner 5 shown in Fig. 3 rotates.

[0013] The operating cord 4 is configured in a ring shape. As shown in FIGS. 1A and 1B, the operating cord 4 hangs down from the left side of the hanger rail 1 and can be grasped by a user. The operating cord 4 is connected to a leading runner 5A (see FIG. 1A), and each runner 5 is connected via a thin, elongated spacer 5s (see FIGS. 2 and 3). For example, when a user operates the operating cord 4 to pull out the shielding material 6, the leading runner 5A is pulled out by the operating cord 4 and moves to the right side, which is the other end side in FIG. 1A. Thereafter, the following runners 5 move sequentially to the right at equal intervals via the spacers 5s. Conversely, when a user operates the operating cord 4 to fold the shielding material 6, the leading runner 5A is pulled back by the operating cord 4 and moves to the left side in FIG. 1A, and the following runners 5 also move to the left side. In this way, the runners 5 are provided on the hanger rail 1 so as to be freely movable in the left-right direction.

[0014] As shown in Fig. 1A, the runner 5 is attached to the tilt shaft 2 and has the function of transmitting the rotation of the tilt shaft 2 to each shielding material unit 6U via a screen hanger 10 (described later). As shown in Fig. 3, the runner 5 has a case portion 5a, a gear mechanism portion 5b, a shaft portion 5c, and a hanging portion 5d.

[0015] The case 5a is provided with a gear mechanism 5b and a shaft 5c. The gear mechanism 5b has a gear into which the tilt shaft 2 is inserted and a gear that transmits the rotation of this gear to the shaft 5c, and when the tilt shaft 2 rotates, the various gears of the gear mechanism 5b rotate, causing the shaft 5c to rotate. The rotation of the shaft 5c then causes the shielding material unit 6U to rotate. The shaft 5c is provided to protrude from the case 5a, and a hanging portion 5d is formed at the lower end of the shaft 5c.

[0016] 2. Structure of the shielding material 6 In the present embodiment, as shown in Figures 1A and 2, the shielding material 6 is configured by connecting a plurality of shielding material units 6U to one another. As shown in Figures 4A and 4B, the shielding material unit 6U includes a shielding member 60, a first hanger member 61, and a second hanger member 62. The first hanger member 61 is attached to an upper portion of the shielding member 60 at one end side in the width direction. The second hanger member 62 is attached to an upper portion of the shielding member 60 at the other end side in the width direction. As shown in Figure 2, the first hanger member 61 of one of the shielding material units 6U and the second hanger member 62 of the other of the adjacent shielding material units 6U are fixed together, thereby connecting the respective shielding material units 6U to one another.

[0017] 4A and 4B, seams 7 are provided along side edges 6Ua, 6Ub on one end and the other end of the shielding material unit 6U in the width direction. Therefore, seams 7 are provided along side edges 6a, 6b (shown in FIG. 2) on one end and the other end of the shielding material 6 in the width direction. The side edge 6a is the side edge 6Ua of the shielding material unit 6U provided at the end on one end side, and the side edge 6b is the side edge 6Ub of the shielding material unit 6U provided at the end on the other end side. In the shielding device 100, when the shielding material 6 is in the shielding state as shown in FIG. 7B, the side edges 6a, 6b may bend, which may result in poor shielding performance in the shielding state shown in FIG. 7B or poor design in the open state shown in FIG. 7A. However, by providing seams 7 along the side edges 6a, 6b, the curvature of the side edges 6a, 6b is suppressed, thereby improving shielding performance and design. In this embodiment, seams 7 are provided along the side edges 6Ua, 6Ub of all of the shielding material units 6U, which suppresses curvature of the side edges 6Ua, 6Ub and thereby particularly improves design. On the other hand, from the perspective of improving shielding properties, seams 7 may be provided only along the side edges 6a, 6b.

[0018] The seams 7 are preferably formed with a sewing machine. The seams 7 can be formed by alternately piercing the front and back of the fabric with a threaded needle. In this embodiment, the seams 7 are formed on a single piece of fabric, but they may also be formed by overlapping and sewing together multiple pieces of fabric. The seams 7 are preferably linear. The seams 7 are preferably arranged parallel to the side edges 6Ua, 6Ub, 6a, and 6b. The distance between the seams 7 and the side edges 6Ua, 6Ub, 6a, and 6b is, for example, 1 to 20 mm, and preferably 2 to 10 mm. Specific examples of this distance include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 mm, and may be within a range between any two of the values ​​exemplified here.

[0019] If the total length of the side edges 6a, 6b of the shielding material 6 or the side edges 6Ua, 6Ub of the shielding material unit 6U is L (shown in FIG. 1), and the length of the portion where the seam 7 is provided along the side edges 6a, 6b or along the side edges 6Ua, 6Ub is L1, then L1 / L is preferably 0.8 or greater. By providing the seam 7 over such a wide range, the curvature of the side edges 6Ua, 6Ub, 6a, 6b is further suppressed. Specific examples of L1 / L are 0.80, 0.85, 0.90, 0.95, and 1.00, and may be within a range between any two of the values ​​exemplified here.

[0020] Each component included in the shielding unit 6U will be described in more detail below.

[0021] <Shielding member 60> 1B, 4A, and 4B, the shielding member 60 includes a lace portion 60a and a pair of drape portions 60b, with the lace portion 60a being provided between the pair of drape portions 60b. The shielding member 60 is made of cloth, and the lace portion 60a and the pair of drape portions 60b are integrally formed by sewing. Side edges 6Ua, 6Ub are provided on the drape portions 60b, and the seams 7 are formed on the drape portions 60b.

[0022] 4B, a folded portion 60c that protrudes above the lace portion 60a is formed at the top of each drape portion 60b during the manufacturing process. The shielding member 60 is then folded back at the folded portion 60c to the rear side, and the first hanger member 61 and the second hanger member 62 are disposed between the drape portion 60b and the folded portion 60c, and are then attached with double-sided tape or adhesive, thereby fixing the first hanger member 61 and the second hanger member 62. Here, the shielding member 60 of this embodiment is configured so that the first hanger member 61 is fixed to the upper left side when viewed from the front, and the second hanger member 62 is fixed to the upper right side of the first hanger member 61, but these may be fixed in reverse.

[0023] Additionally, holes 60d are formed in the drape portion 60b and the folded portion 60c to expose to the outside a first fixing member 61b of the first hanger member 61 and a second fixing member 62b of the second hanger member 62, which will be described later. Also, long holes 60e are formed in the drape portion 60b and the folded portion 60c, continuing beyond the folded portion, to accommodate the suspended portion 61c of the first hanger member 61.

[0024] It should be noted that the first hanger member 61 and the second hanger member 62 can also be fixed to the shielding member 60 by bag stitching, rather than by adhering to the drape portion 60b and the folded portion 60c. However, bag stitching can cause the fabric to swell, increasing the gap between the pieces of fabric, which can impair the design, so it is preferable to use double-sided tape or the like to attach them.

[0025] <First hanger member 61> As shown in FIGS. 5 and 6A, the first hanger member 61 includes a first base member 61a and a pair of first fixing members 61b that are separate from the first base member 61a and are attached to the first base member 61a. The first base member 61a is thin and molded from, for example, resin. The first base member 61a is formed with a suspended portion 61c for hanging from the hanging portion 5d of the runner 5 and a pair of through-holes 61d (see FIG. 6A) for fixing the pair of first fixing members 61b, at approximately the same height. As a result, the suspended portion 61c and the pair of first fixing members 61b are located at approximately the same height. The first base member 61a is also hollowed out to the extent that it does not impair its strength as a hanger.

[0026] 6A, the first fixing member 61b is composed of a clamp 61b1 having a protruding portion of a so-called American hook (also called a ring snap) and a claw 61b2. The first fixing member 61b is attached to the through-hole 61d of the first base member 61a by sandwiching the first base member 61a between the clamp 61b1 and the claw 61b2.

[0027] <Second hanger member 62> On the other hand, as shown in FIGS. 5 and 6B, the second hanger member 62 includes a second base member 62a and a pair of second fixing members 62b that are separate from the second base member 62a and are attached to the second base member 62a. The second base member 62a is thin and molded, for example, from resin. A pair of through-holes 62d (see FIG. 6B) for fixing the pair of second fixing members 62b are formed in the second base member 62a at approximately the same height. The second base member 62a is also hollowed out to the extent that it does not impair its strength as a hanger. The second base member 62a does not have a suspended portion for hanging from the suspending portion 5d of the runner 5. Instead, a notch 62c is formed at a position corresponding to the suspended portion 61c of the first base member 61a to prevent interference with the suspending portion 5d. In this embodiment, the first base member 61a and the second base member 62a differ only in whether or not they have a suspended portion, and the other configurations are the same.

[0028] 6B, the second fixing member 62b is composed of a spring 62b1 having a recessed portion of an American hook and a claw 62b2 (the same as the claw 61b2 of the first fixing member 61b). The second fixing member 62b is attached to the position of the through-hole 62d of the second base member 62a so that the second base member 62a is sandwiched between the spring 62b1 and the claw 62b2.

[0029] The first fixing member 61b and the second fixing member 62b that constitute the American hook may be made of metal or resin.

[0030] <Function as Screen Hanger 10> 3 and 5, the first hanger member 61 and the second hanger member 62 configured as described above are respectively fixed to a pair of first fixing members 61b and a pair of second fixing members 62b that form American hooks, thereby forming a screen hanger 10 that is hung from the hanging portion 5d of the runner 5 and supports the shielding member 60. More specifically, the screen hanger 10 of this embodiment is made up of a second hanger member 62 provided on the right side of the left shielding material unit 6U of adjacent shielding material units 6U, and a first hanger member 61 provided on the left side of the right shielding material unit 6U.

[0031] When the shaft 5c of each runner 5 is rotated by operating the tilt operation rod 3 described above, the screen hanger 10 rotates, causing the shielding material 6 (each shielding material unit 6U) to transition (rotate) between the open state and the closed state (see FIGS. 7A and 7B). Also, when the runner 5 moves to the right or left, the screen hanger 10 moves to the right or left, and the shielding material 6 is pulled out or folded in.

[0032] 3. Other configurations of the shielding material 6 The shielding material 6 of this embodiment is constructed by connecting a plurality of shielding material units 6U having the above-described configuration to the runners 5 of the hanger rail 1 in a suspended manner.

[0033] Specifically, the suspended portion 61c of the first hanger member 61 of each shielding material unit 6U is hooked onto the hanging portion 5d of the runner 5, and the first fixing member 61b of the first hanger member 61 and the second fixing member 62b of the second hanger member 62 of the left-side shielding material unit 6U are fixed. By performing this work in sequence, the shielding material 6 is constructed.

[0034] In this embodiment, as shown in Figures 2 and 8A, the shielding material unit 6U arranged on the far left (hereinafter referred to as the left-end shielding material unit 6UL) has a first hanger member 61 (hereinafter referred to as the left-end first hanger member 61L) on the left side that does not have a first fixing member 61b and is made up of only a first base member 61a. Also, as shown in Figures 2 and 8B, the shielding material unit 6U arranged on the far right (hereinafter referred to as the right-end shielding material unit 6UR) has a first hanger member 61 (hereinafter referred to as the right-end first hanger member 61R) on the right side that has a suspended portion 61c instead of the second hanger member 62. However, the right-end first hanger member 61R also does not have a first fixing member 61b and is made up of only a first base member 61a. The side edge 6Ua at one end of the first hanger member 61L for the left end becomes the side edge 6a at one end of the shielding material 6, and the side edge 6Ub at the other end of the first hanger member 61R for the right end becomes the side edge 6b at the other end of the shielding material 6.

[0035] On the other hand, when removing the shielding material 6 of this embodiment from the runner 5, the opposite procedure is followed: the first fixing member 61b and the second fixing member 62b of the adjacent shielding material unit 6U are released from their respective fixing members, and the hanging portion 61c of the first hanger member 61 of each shielding material unit 6U is removed from the hanging portion 5d of the runner 5.

[0036] 4. Effects (1) In the shielding material 6 according to this embodiment, the first base member 61a and the first fixing member 61b of the first hanger member 61 are configured as separate members, and the left-end first hanger member 61L and the right-end first hanger member 61R are configured without the first fixing member 61b. This prevents the first fixing member 61b from protruding to the left of the left-end shielding unit 6UL or to the right of the right-end shielding unit 6UR, improving the design of the shielding material 6. Furthermore, the first hanger members 61 of the intermediate shielding material unit 6U, the left-end shielding material unit 6UL, and the right-end shielding material unit 6UR can be configured using a common first base member 61a, making it possible to reduce the number of parts.

[0037] (2) In each shielding material unit 6U of this embodiment, the suspended portion 61c of the first hanger member 61 and the pair of first fixing members 61b are provided at approximately the same height. This means that each shielding material unit 6U is connected at the upper end position, and compared to when the first fixing members 61b are located below the suspended portion 61c, it is possible to suppress the spread of the upper end portion of the shielding member 60 and improve the design.

[0038] (3) In the shielding material 6 of this embodiment, the seams 7 are provided along the side edges 6a, 6b, which prevents the side edges 6a, 6b from curving, improving shielding properties and design.

[0039] 5. Variations The present invention can also be implemented in the following aspects.

[0040] In the above embodiment, the first fixing member 61b and the second fixing member 62b are configured by American hooks. However, the configuration of the first fixing member 61b and the second fixing member 62b for fixing the first hanger member 61 and the second hanger member 62 is not limited to this. For example, the first fixing member 61b and the second fixing member 62b can also be configured by zippers, hook-and-loop fasteners, or other engaging means.

[0041] In the above embodiment, the first hanger member 61 is made up of the first base member 61a and the first fixing member 61b, which is a separate member, and the second hanger member 62 is made up of the second base member 62a and the second fixing member 62b, which is a separate member. However, since the second hanger member 62 does not have a hanging portion and is not used at the end, the second base member 62a and the second fixing member 62b may be molded integrally.

[0042] In the above embodiment, the first hanger member 61 and the second hanger member 62 are each made up of multiple members, but one or both of the first hanger member 61 and the second hanger member 62 may be made up of a single member, which makes it possible to reduce the number of parts.

[0043] 6. Working Example 9A shows an example implementation of a shielding device 100 according to one embodiment of the present invention. This shielding device 100 includes two shielding materials 6A and 6B, which are in a shielding state. The shielding materials 6A and 6B have seams 7 along a side edge 6a at one end and a side edge 6b at the other end. In FIG. 9A, the side edge 6b of the shielding material 6A and the side edge 6a of the shielding material 6B are close to each other, and neither of the side edges 6a and 6b is curved. This leaves almost no gap between the side edges 6a and 6b, achieving excellent shielding properties.

[0044] 9B shows a comparative example of a shading device 100X, which has the same configuration as that of FIG. 9A except that it does not have seams 7. In the shading device 100X, the side edge 6b of the shielding material 6A and the side edge 6a of the shielding material 6B are each curved, and therefore a gap is formed between the side edges 6a and 6b near the lower ends of the shielding materials 6A and 6B, resulting in poor shielding properties.

[0045] It has been found that by providing the seams 7 along the side edges 6a and 6b in this way, the curvature of the side edges 6a and 6b is suppressed, improving the shielding properties. [Explanation of symbols]
