DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present invention will be described. Various features shown in the following embodiments can be combined with each other. Also, 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 hanger rail 1 is configured in a case shape and is attached, for example, to the wall surface, ceiling, or window frame of a building. A tilt shaft 2 and multiple runners 5 are housed inside the 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 side 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 hanger rail 1 on the left side of the hanger rail 1 and can be held by the user. The operating cord 4 is connected to the leading runner 5A (see Fig. 1A), and each runner 5 is connected via a long, thin 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 as the other end side in Fig. 1A, and then the following runners 5 move to the right side at equal intervals via the spacer 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 axis 2 and has a function of transmitting the rotation of the tilt axis 2 to each shielding material unit 6U via a screen hanger 10 described later. As shown in FIG. 3, the runner 5 includes a case portion 5a, a gear mechanism portion 5b, a shaft portion 5c, and a suspension portion 5d.

[0015] The gear mechanism portion 5b and the shaft portion 5c are provided in the case portion 5a. The gear mechanism portion 5b includes a gear into which the tilt axis 2 is inserted and gears that transmit the rotation of this gear to the shaft portion 5c. When the tilt axis 2 rotates, the various gears of the gear mechanism portion 5b rotate, and the shaft portion 5c rotates. Then, when the shaft portion 5c rotates, the shielding material unit 6U rotates. The shaft portion 5c is provided so as to protrude from the case portion 5a, and a suspension portion 5d is formed at the lower end portion of the shaft portion 5c.

[0016] 2. Configuration of the shielding material 6 In the present embodiment, as shown in FIGS. 1A and 2, the shielding material 6 is configured by connecting a plurality of shielding material units 6U to each other. As shown in FIGS. 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 one end side in the width direction at the upper part of the shielding member 60. The second hanger member 62 is attached to the other end side in the width direction at the upper part of the shielding member 60. As shown in FIG. 2, by fixing one first hanger member 61 and the other second hanger member 62 of adjacent shielding material units 6U, the respective shielding material units 6U are connected to each other.

[0017] As shown in FIGS. 4A and 4B, seams 7 are provided along the respective side edges 6Ua, 6Ub on one end side and the other end side in the width direction of the shielding material unit 6U. For this reason, seams 7 are provided along the respective side edges 6a, 6b (shown in FIG. 2) on one end side and the other end side in the width direction of the shielding material 6. 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. When the shielding material 6 is in the shielding state as shown in FIG. 7B in the shielding device 100, the side edges 6a, 6b may be curved and the shielding property in the shielding state shown in FIG. 7B may deteriorate, or the design property in the open state shown in FIG. 7A may deteriorate. By providing the seams 7 along the side edges 6a, 6b, the bending of the side edges 6a, 6b is suppressed, and the shielding property and the design property are improved. In the present embodiment, seams 7 are provided along the side edges 6Ua, 6Ub of all the shielding material units 6U, whereby the bending of each side edge 6Ua, 6Ub is suppressed, and the design property is particularly improved. On the other hand, from the viewpoint of improving the shielding property, only the seams 7 along the side edges 6a, 6b may be provided.

[0018] The seam 7 is preferably formed by a sewing machine. The seam 7 can be formed by alternately piercing a needle passed through a thread into the front and back of the fabric and advancing it. In the present embodiment, the seam 7 is formed on a single piece of fabric, but it may also be formed by sewing a plurality of pieces of fabric together. The seam 7 is preferably linear. The seam 7 is preferably provided parallel to the side edges 6Ua, 6Ub, 6a, 6b. The distance between the seam 7 and the side edges 6Ua, 6Ub, 6a, 6b is, for example, 1 to 20 mm, and preferably 2 to 10 mm. Specifically, this distance is, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 mm, and may be in the range between any two of the numerical values exemplified here.

[0019] Let the total length of the side edges 6a and 6b of the shielding material 6 or the side edges 6Ua and 6Ub of the shielding material unit 6U be L (shown in FIG. 1), and when the length of the portion where the seam 7 is provided along the side edges 6a and 6b or along the side edges 6Ua and 6Ub is L1, it is preferable that L1 / L is 0.8 or more. By providing the seam 7 over such a wide range, the bending of the side edges 6Ua, 6Ub, 6a, and 6b is further suppressed. Specifically, L1 / L is, for example, 0.80, 0.85, 0.90, 0.95, 1.00, and it may also be in the range between any two of the numerical values exemplified here.

[0020] Hereinafter, each component included in the shielding material unit 6U will be described in more detail.

[0021] <Shielding member 60> As shown in FIGS. 1B, 4A, and 4B, the shielding member 60 includes a race portion 60a and a pair of drape portions 60b, and the race portion 60a is provided between the pair of drape portions 60b. The shielding member 60 is made of a cloth fabric, and the race portion 60a and the pair of drape portions 60b are integrally formed by sewing. The side edges 6Ua and 6Ub are provided on the drape portion 60b, and the seam 7 is formed on the drape portion 60b.

[0022] As shown in FIG. 4B, at the upper part of each drape portion 60b, a folded-back portion 60c that protrudes above the race portion 60a in the manufacturing process is formed. Then, the shielding member 60 folds back the folded-back portion 60c to the back side, arranges the first hanger member 61 and the second hanger member 62 between the drape portion 60b and the folded-back portion 60c, and adheres them with double-sided tape or an adhesive to fix the first hanger member 61 and the second hanger member 62. Here, the shielding member 60 of the present embodiment is configured to fix the first hanger member 61 on the upper part and on the left side in the front view, and fix the second hanger member 62 on the upper part and on the right side, but these may be fixed by swapping them.

[0023] In addition, holes 60d are formed in the drape portion 60b and the folded-back portion 60c to expose the first fixing member 61b of the first hanger member 61 and the second fixing member 62b of the second hanger member 62, which will be described later, to the outside. Further, long holes 60e that are continuous beyond the folded-back portion are formed in the drape portion 60b and the folded-back portion 60c to dispose the suspended portion 61c of the first hanger member 61.

[0024] Note that the first hanger member 61 and the second hanger member 62 can be fixed to the shielding member 60 by bag sewing instead of adhering to the drape portion 60b and the folded-back portion 60c. However, in the case of bag sewing, the fabric bulges and the gap between the fabrics becomes large, which may impair the design quality. Therefore, it is preferable to adhere with double-sided tape or the like.

[0025] <The 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 members from the first base member 61a and are attached thereto. The first base member 61a is in a thin plate shape and is formed of, for example, resin. A suspended portion 61c for suspending from the suspension 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 are formed at substantially the same height on the first base member 61a. Thereby, the suspended portion 61c and the pair of first fixing members 61b are provided at substantially the same height. Further, the first base member 61a is cut out to such an extent that the strength as a hanger is not impaired.

[0026] As shown in FIG. 6A, the first fixing member 61b is composed of a hook 61b1 having a convex 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 position of the through hole 61d of the first base member 61a so as to sandwich the first base member 61a with the hook 61b1 and the claw 61b2.

[0027] <The second hanger member 62> On the other hand, as shown in FIG. 5 and FIG. 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 thereto. The second base member 62a is thin plate-shaped and is 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 an extent that does not impair the strength of the hanger. The second base member 62a does not have a hanging portion for hanging from the hanging portion 5d of the runner 5. Instead, a notch 62c is formed at a position corresponding to the hanging portion 61c of the first base member 61a to prevent interference with the hanging portion 5d. In this embodiment, the only difference between first base member 61a and second base member 62a is 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 recess of an American hook and a claw 62b2 (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 as to sandwich the second base member 62a 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 fixed to a pair of first fixing members 61b and a pair of second fixing members 62b constituting American hooks, thereby constituting the screen hanger 10 that is suspended from the suspension portion 5d of the runner 5 and supports the shielding member 60. More specifically, the screen hanger 10 of this embodiment is composed of the second hanger member 62 provided on the right side of the left shielding material unit 6U in adjacent shielding material units 6U, and the first hanger member 61 provided on the left side of the right shielding material unit 6U.

[0031] When the shaft portion 5c of each runner 5 rotates by operating the tilt operation rod 3 described above, the screen hanger 10 rotates, and this causes 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 up.

[0032] 3. Other configurations of the shielding material 6 The shielding material 6 of the present 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 shielding material unit 6U are fixed. By performing this procedure in sequence, the shielding material 6 is constructed.

[0034] In this embodiment, the shielding material unit 6U arranged on the left side (hereinafter referred to as the left end shielding material unit 6UL) does not have a first fixing member 61b in the first hanger member 61 (hereinafter referred to as the left end first hanger member 61L) arranged on the left side, and is composed of only the first base member 61a, as shown in Fig. 2 and Fig. 8A. Also, the shielding material unit 6U arranged on the right side (hereinafter referred to as the right end shielding material unit 6UR) is provided with a first hanger member 61 (hereinafter referred to as the right end first hanger member 61R) having a suspended part 61c instead of the second hanger member 62 on its right side, as shown in Fig. 2 and Fig. 8B. However, the right end first hanger member 61R does not have a first fixing member 61b either, and is composed of only the first base member 61a. The side edge 6Ua at one end of the first left end hanger member 61L 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 right end hanger member 61R 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 process is performed by releasing the fixation of the first fixing member 61b and the second fixing member 62b of the adjacent shielding material unit 6U, and removing the suspended portion 61c of the first hanger member 61 of each shielding material unit 6U 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 makes it possible to improve the design of the shielding material 6, since the first fixing member 61b does not protrude to the left side of the left-end shielding material unit 6UL or to the right side of the right-end shielding material unit 6UR. In addition, 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 allows each shielding material unit 6U to be connected at the upper end position, and compared to a case in which the first fixing members 61b are located lower than the suspended portions 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 the present 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 be configured by a fastener, a hook-and-loop fastener, or other engaging means.

[0041] In the above embodiment, the first hanger member 61 is composed of the first base member 61a and the first fixing member 61b which is a separate member, and the second hanger member 62 is composed 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 integrally formed.

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

[0043] 6. Working Example 9A shows an example of mounting the shielding device 100 according to an embodiment of the present invention. In this shielding device 100, two shielding materials 6A and 6B are provided, and the shielding materials 6A and 6B are in a shielding state. The shielding materials 6A and 6B are provided with seams 7 along the side edge 6a on one end side and the side edge 6b on the other end side. 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 are curved, so there is almost no gap between the side edges 6a and 6b, and good shielding properties are achieved.

[0044] Fig. 9B shows a comparative shading device 100X, which has the same configuration as Fig. 9A except that it does not have a seam 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, so that a gap is formed between the side edges 6a, 6b near the bottom ends of the shielding materials 6A, 6B, resulting in poor shielding properties.

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