DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the present embodiment will be described with reference to the drawings. Figures 1 to 8 are diagrams showing a curtain hanging device according to the present embodiment and a curtain unit equipped with such a curtain hanging device.

[0012] First, the overall configuration of the curtain unit will be described with reference to Fig. 6 etc. As shown in Fig. 6, the curtain unit includes a linearly extending curtain rail 90, a pair of a first curtain 60 and a second curtain 70 on the left and right, a first curtain hanger 10 that is movable along the curtain rail 90 and for hanging the first curtain 60, and a second curtain hanger 20 that is movable along the curtain rail 90 and for hanging the second curtain 70.

[0013] The first curtain hanger 10 is capable of mounting a first hanger 62 for hanging a first curtain 60. The first curtain hanger 10 is also detachable from the second curtain hanger 20.

[0014] More specifically, as shown in Figs. 1 to 3, the first curtain hanger 10 has a main body 12, a pair of rollers 14 provided on the upper part of the main body 12, a through hole 16 to which the first hanging tool 62 is hooked, and a magnet 18. Each roller 14 runs on a curtain rail 90. As each roller 14 runs on the curtain rail 90, the first curtain hanger 10 slides in the left-right direction in Fig. 6 and the like along the curtain rail 90. Also, as shown in Fig. 6 and the like, two first hanging tools 62 for hanging the first curtain 60 are hooked on the through holes 16, respectively. The first hanging tools 62 hooked on such through holes 16 are capable of supporting the upper part of the first curtain 60 near the side edge 60a.

[0015] The second curtain hanger 20 has a main body portion 22 to which a second hanging device 72 for hanging the second curtain 70 can be attached, an attachment portion 50 that is provided separately from the main body portion 22 and to which a third hanging device 74 for hanging the second curtain 70 can be attached, and a connection portion 36 that connects the main body portion 22 and the attachment portion 50.

[0016] The second curtain hanger 20 further includes a pair of rollers 24 provided on the upper part of the main body 22, a through hole 26 to which the second hanging tool 72 is hooked, a winding mechanism 30 for winding the connection part 36, and a plate-shaped metal member 46. Each roller 24 runs on a curtain rail 90. As each roller 24 runs on the curtain rail 90, the second curtain hanger 20 slides in the left-right direction along the curtain rail 90 in FIG. 6 and other figures. As shown in FIG. 6 and other figures, a second hanging tool 72 for hanging the second curtain 70 is hooked on the through hole 26. The second hanging tool 72 hooked on the through hole 26 can support the upper part of the second curtain 70 at a position slightly away from the side edge 70a.

[0017] The mounting part 50 is connected to the main body part 22 by a connecting part 36. More specifically, the connecting part 36 is, for example, a string-like member 36a. As shown in Figures 6 to 8, the mounting part 50 is provided with a gripping member 52 that detachably grips a third hanging tool 74 for suspending the second curtain 70. The third hanging tool 74 gripped by this gripping member 52 is capable of supporting an upper part of the second curtain 70 near the side edge 70a.

[0018] The mounting portion 50 includes a metal member 50a. As shown in Figs. 6 and 7, the first curtain 60 is provided with a mounting receiving portion 64 to which the mounting portion 50 is detachably attached. Specifically, the mounting receiving portion 64 is provided at a location slightly away from the side edge 60a of the first curtain 60 on the side closer to the second curtain 70. The mounting receiving portion 64 includes a magnet, and the magnet is attached to the metal member 50a by magnetic force, thereby allowing the mounting portion 50 to be detachably attached to the mounting receiving portion 64. In this embodiment, the distance between the side edge 60a of the first curtain 60 on the side closer to the second curtain 70 and the mounting receiving portion 64 is shorter than the length of the connection portion 36 (specifically, the string-like member 36a).

[0019] The winding mechanism 30 is configured to wind the connection portion 36 (specifically, the string-like member 36a) inside the main body portion 22. The configuration of the winding mechanism 30 will be described in detail with reference to Figs. 4 and 5.

[0020] As shown in FIG. 4 and other figures, the winding mechanism 30 includes a substantially disk-shaped rotating body 32 that can rotate around an axis 31, a biasing member 34 that applies a force to the rotating body 32 to rotate the connecting portion 36 in the winding direction (counterclockwise direction in FIG. 4 and other figures), and a disk-shaped gear member 35 that can rotate integrally with the rotating body 32 around the axis 31. In such a winding mechanism 30, the connecting portion 36 (specifically, the string-shaped member 36a) is wound around the outer circumferential surface of the rotating body 32 by rotating the rotating body 32 in the counterclockwise direction in FIG. 4 and other figures. The force that rotates the rotating body 32 in the counterclockwise direction in FIG. 4 and other figures is applied by the biasing member 34. The biasing member 34 includes, for example, a leaf spring. With such a biasing member 34, it becomes possible to constantly apply a force that rotates the rotating body 32 in the counterclockwise direction in FIG. 4 and other figures to the rotating body 32 even if no power is applied from the outside.

[0021] When no force is applied to the second curtain hanger 20, the winding mechanism 30 winds the connection part 36 inside the main body part 22, so that the mounting part 50 is maintained in a position near the main body part 22 as shown in Figure 1. On the other hand, even if an operator moves the mounting part 50 away from the main body part 22 by pulling on it, when the operator releases the mounting part 50, the winding mechanism 30 winds the connection part 36 inside the main body part 22, so that the mounting part 50 is returned to a position near the main body part 22.

[0022] The second curtain hanger 20 also has a restricting means 37 that restricts the winding mechanism 30 from winding up the connection portion 36, and a detection unit 40 that detects that the first curtain hanger 10 is attached to the second curtain hanger 20. The restricting means 37 restricts the winding mechanism 30 from winding up the connection portion 36 when the detection unit 40 detects that the first curtain hanger 10 is attached to the second curtain hanger 20.

[0023] The restraining means 37 has a stopper member 38 that rotates around a shaft 38a. A protruding portion 38b is provided near the end of the stopper member 38, and this protruding portion 38b is adapted to mesh between the teeth of the gear member 35. More specifically, as shown in Figs. 4 and 5, the outer circumferential surface of the gear member 35 includes a plurality of protruding portions 35a, a recessed portion 35b between each of the protruding portions 35a, and a transition portion 35c that is curved to bulge outward and is between the protruding portions 35a and the recessed portions 35b. Then, as shown in Fig. 5, when the stopper member 38 rotates in a clockwise direction around the shaft 38a and the protruding portion 38b approaches the gear member 35 and enters the recessed portion 35b of the gear member 35, the protruding portion 38b gets caught by the protruding portion 35a, so that the gear member 35 cannot rotate in a counterclockwise direction in Fig. 5. This prevents the winding up of the connection portion 36 by the winding mechanism 30. On the other hand, even if the protruding portion 38b enters the recessed portion 35b of the gear member 35, when the gear member 35 rotates in the clockwise direction in Fig. 5, the protruding portion 38b moves relatively from the recessed portion 35b of the gear member 35 through the transition portion 35c to the convex portion 35a while in contact with the transition portion 35c, and thus overcomes the convex portion 35a, and the protruding portion 38b does not get caught on the convex portion 35a. Therefore, the gear member 35 can continue to rotate in the clockwise direction in Fig. 4 etc.

[0024] The detector 40 includes an elongated pin member, a portion of which protrudes outward from the main body 22 toward the first curtain hanger 10. When the first curtain hanger 10 is attached to the second curtain hanger 20, the detector 40 is pushed into the main body 22 as shown in Figs. 3 and 5. In this manner, the detector 40 is able to detect that the first curtain hanger 10 has been attached to the second curtain hanger 20. One end of a first spring 42 is attached to the detector 40, and the other end of the first spring 42 is attached to a location on the back side of the protruding portion 38b of the stopper member 38. One end of a second spring 44 is attached to the metal member 46, and the other end of the second spring 44 is attached to a location on the stopper member 38 below the shaft 38a. Here, the location of the stopper member 38 where the first spring 42 is attached and the location of the second spring 44 are attached are on opposite sides of the shaft 38a.

[0025] When the first curtain hanger 10 is attached to the second curtain hanger 20 and the detector 40 is pushed into the main body 22 as shown in Figures 3 and 5, the first spring 42 attached to the detector 40 is compressed, and the first spring 42 pushes the stopper member 38 toward the gear member 35. This causes the stopper member 38 to rotate about the shaft 38a, and the protruding portion 38b enters the recessed portion 35b of the gear member 35, preventing the winding mechanism 30 from winding up the connection portion 36. In addition, the second spring 44 is pressed by the stopper member 38 and is compressed. On the other hand, when the first curtain hanger 10 moves away from the second curtain hanger 20, the force of the second spring 44 trying to return from the compressed state causes the stopper member 38 to rotate counterclockwise about the shaft 38a. As a result, the first spring 42 is pushed to the left in FIGS. 4 and 5, and the detection unit 40 is also pushed by the first spring 42, returning to a state in which it protrudes outward from the main body unit 22 as shown in FIG.

[0026] 7 and 8, a plurality of first slide members 80 are provided on the curtain rail 90 to the left of the first curtain hanger 10, and each first slide member 80 is movable along the curtain rail 90. A fourth hanger 63 for hanging the first curtain 60 can be attached to each first slide member 80. In this way, a portion near the upper end of the first curtain 60 is hung by the pair of first hangers 62 attached to the first curtain hanger 10 and the plurality of fourth hangers 63 attached to each first slide member 80.

[0027] 7 and 8, a plurality of second slide members 82 are provided on the curtain rail 90 to the right of the second curtain hanger 20, and each second slide member 82 is movable along the curtain rail 90. A fifth hanger 76 for hanging the second curtain 70 can be attached to each second slide member 82. In this manner, a portion near the upper end of the second curtain 70 is hung by the second hanger 72 attached to the main body 22 of the second curtain hanger 20, the third hanger 74 attached to the mounting portion 50 of the second curtain hanger 20, and the plurality of fifth hangers 76 attached to each second slide member 82.

[0028] Next, the operation of such a curtain hanging device will be described with reference to FIGS.

[0029] 6 is a diagram showing a curtain unit in which the first curtain 60 and the second curtain 70 are positioned on both sides of a window and the window is not covered by the first curtain 60 and the second curtain 70. When an operator pulls the first curtain 60 and the second curtain 70 together toward the center of the window from this state to cover the window with the first curtain 60 and the second curtain 70, the operator first pulls the first curtain 60 to move the first curtain hanger 10 and each of the first slide members 80 to the right along the curtain rail 90, and pulls the second curtain 70 to move the second curtain hanger 20 and each of the second slide members 82 to the left along the curtain rail 90. As a result, the side edge 60a of the first curtain 60 and the side edge 70a of the second curtain 70 are close to each other as shown in FIG. Additionally, the magnet 18 of the first curtain hanger 10 attaches to the metal member 46 of the second curtain hanger 20, thereby attaching the first curtain hanger 10 to the second curtain hanger 20.

[0030] After that, the worker pulls the side edge 70a of the second curtain 70 further to the left, moving it further left than the side edge 60a of the first curtain 60 as shown in FIG. 8. At this time, since the portion of the second curtain 70 near the side edge 70a is suspended by the third suspension tool 74, the mounting part 50 provided with the gripping member 52 for gripping the third suspension tool 74 moves away from the main body part 22 of the second curtain suspension tool 20. That is, the connection part 36 (specifically, the string-like member 36a) is unwound from the winding mechanism 30. As described above, even if the first curtain suspension tool 10 is attached to the second curtain suspension tool 20 and the protruding part 38b of the stopper member 38 enters the recessed part 35b of the gear member 35, the gear member 35 and the rotating body 32 can be rotated clockwise around the shaft 31, so that the connection part 36 can be unwound from the winding mechanism 30. On the other hand, when the first curtain hanger 10 is attached to the second curtain hanger 20, the winding of the connection part 36 by the winding mechanism 30 is prevented by the prevention means 37. Then, the worker attaches the attachment part 50 to the attachment receiving part 64 of the first curtain 60. Specifically, the metal member 50a of the attachment part 50 is attached to the magnet of the attachment receiving part 64. By attaching the attachment part 50 to the attachment receiving part 64 in this manner, the first curtain 60 and the second curtain 70 are maintained in an overlapped state as shown in FIG. 8. As a result, the area between the side edge 70a of the second curtain 70 and the side edge 60a of the first curtain 60 (the area indicated by reference symbol A in FIG. 8) is in an overlapped state, so that it is possible to prevent a gap from occurring between the first curtain 60 and the second curtain 70 that are pulled together toward the center.

[0031] When opening the first curtain 60 and the second curtain 70 from the state shown in FIG. 8, the worker pulls the second curtain 70 to the right. Then, when the worker pulls the second curtain 70 to the right and the second curtain hanger 20 separates from the first curtain hanger 10, the detection unit 40 is no longer pushed into the inside of the main body 22 by the first curtain hanger 10, and the stopper member 38 rotates counterclockwise around the shaft 38a due to the force of the second spring 44 trying to return from the compressed state. As a result, the first spring 42 is pushed to the left in FIGS. 4 and 5, and the detection unit 40 is also pushed by the first spring 42 and returns to a state protruding outward from the main body 22 as shown in FIG. 4. In this case, the connection unit 36 ​​is wound by the winding mechanism 30, so that the attachment unit 50 is automatically returned to a position near the main body 22 as shown in FIG. 1. In this way, the first curtain 60 and the second curtain 70 can be opened to the left and right from the window.

[0032] According to the curtain hanging device and curtain unit of the present embodiment configured as described above, the second curtain hanger 20 is provided separately from the main body 22 and has the mounting part 50 to which the third hanger 74 for hanging the second curtain 70 can be attached, so that when the pair of the left and right first curtain 60 and second curtain 70 are pulled together toward the center of the window, no gap is generated in the central pulled-together part. Furthermore, such a curtain hanging device and curtain unit can be applied to an existing curtain rail 90 that extends in a straight line.

[0033] Furthermore, in this embodiment, the first curtain 60 is provided with a mounting portion 64 to which the mounting part 50 is detachably attached, and the distance between the side edge 60a of the first curtain 60 closer to the second curtain 70 and the mounting portion 64 is shorter than the length of the connection part 36. In this case, the mounting part 50, which is connected to the main body 22 of the second curtain hanger 20 by the connection part 36, can be securely attached to the mounting portion 64.

[0034] Furthermore, in this embodiment, the connection part 36 is a string-like member 36a, and the main body part 22 of the second curtain hanger 20 is provided with a winding mechanism 30 for winding the connection part 36 inside the main body part 22. In this case, by winding the connection part 36 inside the main body part 22 by the winding mechanism 30, the attachment part 50 can be automatically returned to a position near the main body part 22 when the first curtain 60 and the second curtain 70 are opened.

[0035] The second curtain hanger 20 also has a restricting means 37 for restricting the winding mechanism 30 from winding up the connection portion 36, and a detection unit 40 for detecting that the first curtain hanger 10 is attached to the second curtain hanger 20, and the restricting means 37 restricts the winding mechanism 30 from winding up the connection portion 36 when the detection unit 40 detects that the first curtain hanger 10 is attached to the second curtain hanger 20. In this case, when the first curtain 60 and the second curtain 70 are pulled together toward the center of the window, the winding mechanism 30 will no longer wind up the connection portion 36, so that the first curtain 60 and the second curtain 70 can maintain their overlapping state.

[0036] The winding mechanism 30 has a rotor 32 that is rotatable about an axis 31, and the rotation of the rotor 32 causes the connection part 36 to be wound around the outer circumferential surface of the rotor 32, and the winding mechanism 30 has a biasing member 34 that applies a force to the rotor 32 to rotate in the winding direction of the connection part 36. In this case, the biasing member 34 can always apply a force to the rotor 32 to rotate in the winding direction of the connection part 36 without applying a force from the outside to the winding mechanism 30. The biasing member 34 may also include a leaf spring.

[0037] In this embodiment, the first curtain hanger 10 can be attached and detached to the second curtain hanger 20 by magnetic force. This allows an operator to easily attach and detach the first curtain hanger 10 to and from the second curtain hanger 20. At least one of the first curtain hanger 10 and the second curtain hanger 20 is provided with a magnet 18. In the above description, an example is shown in which the magnet 18 is provided on the first curtain hanger 10, but the magnet may be provided on the second curtain hanger 20 instead of the first curtain hanger 10, or magnets of opposite polarities may be provided on both the first curtain hanger 10 and the second curtain hanger 20.

[0038] Furthermore, in this embodiment, the mounting part 50 can be attached and detached to the mounted part 64 by magnetic force. This allows the worker to easily attach and detach the mounting part 50 to the mounted part 64. Furthermore, a magnet is provided on at least one of the mounting part 50 and the mounted part 64. In the above explanation, an example has been shown in which a magnet is provided on the mounted part 64, but a magnet may be provided on the mounting part 50 instead of the mounted part 64, or magnets of opposite polarities may be provided on both the mounting part 50 and the mounted part 64.

[0039] The curtain unit and curtain hanging device according to the present embodiment are not limited to the above-described embodiment, and various modifications can be made.

[0040] For example, the second curtain hanger 20 is not limited to having a winding mechanism 30. Even if a second curtain hanger 20 that does not have a winding mechanism 30 is used, it is possible to prevent a gap from occurring in the center of the pulled-together portion when the pair of left and right first and second curtains 60, 70 are pulled together toward the center of the window.

[0041] Furthermore, the connecting portion 36 that connects the main body 22 and the mounting portion 50 of the second curtain hanger 20 is not limited to the string-like member 36a. Anything other than the string-like member 36a may be used as the connecting portion 36 as long as it can connect the main body 22 and the mounting portion 50.

[0042] Furthermore, the first curtain hanger 10 does not have to be detachable from the second curtain hanger 20. Specifically, the first curtain hanger 10 and the second curtain hanger 20 do not have to be provided with magnets or the like. Even in this case, it is possible to prevent a gap from occurring in the center of the pulled-together portion when the pair of left and right first curtain 60 and second curtain 70 are pulled together toward the center of the window.

[0043] Furthermore, in this embodiment, the mounting part 50 is not limited to being detachably attached to the mounting receiving part 64 by magnetic force. For example, a snap button may be provided on one of the mounting part 50 and the mounting receiving part 64, and a receiver for the snap button may be provided on the other, thereby allowing the mounting part 50 to be detachably attached to the mounting receiving part 64.

[0044] In this embodiment, the first curtain hanger 10 as shown in Figs. 1 to 3 may be omitted. That is, even if the first curtain hanger 10 is not installed and only the second curtain hanger 20 is used, when the first curtain 60 is provided with the mounting portion 64, it is possible to prevent a gap from being generated in the central pulled-together portion when the pair of the left and right first and second curtains 60 and 70 are pulled together toward the center of the window. When the first curtain hanger 10 as shown in Figs. 1 to 3 is omitted, the first sliding member 80 functions as "a first curtain hanger that is movable along the curtain rail and to which a first hanging tool for hanging the first curtain can be attached."

[0045] Also, the curtain unit shown in Fig. 9 to Fig. 14 may be used. The curtain unit shown in Fig. 9 etc. includes a curtain rail 90 extending linearly, a first curtain hanger 110 movable along the curtain rail 90 for hanging a first curtain (not shown), and a second curtain hanger 120 movable along the curtain rail 90 for hanging a second curtain (not shown). In such a curtain unit, the first curtain hanger 110 is detachable from the second curtain hanger 120. Details of the curtain unit shown in Fig. 9 to Fig. 14 will be described below.

[0046] As shown in FIG. 9 and other figures, the first curtain hanger 110 has a main body 112, a pair of sliders 114 provided on the upper part of the main body 112, a hook 116 for hooking a first hanger (not shown) for hanging the first curtain, and a magnet 118. Each slider 114 is slidable along the curtain rail 90. Here, the first hanger attached to the upper edge of the first curtain near the side edge closest to the second curtain is hooked onto the hook 116. In addition, as each slider 114 slides along the curtain rail 90, the first curtain hanger 110 slides left and right along the curtain rail 90 in FIG. 10 and other figures.

[0047] The second curtain hanger 120 has a main body 122, a pair of sliders 124 provided on the upper portion of the main body 122, and a hook 126 on which a second hanger (not shown) for hanging the second curtain can be hooked. The second curtain hanger 120 also has an attachment 150 having a through hole 152 formed therein on which a third hanger (not shown) for hanging the second curtain can be hooked, and a connection 136 provided on the main body 122 for connecting the main body 122 and the attachment 150. Here, the third hanger attached to the upper edge of the second curtain near the side edge closest to the first curtain is hooked to the through hole 152 in the attachment 150, and the second hanger second closest to this side edge is hooked to the hook 126. Connection portion 136 provided on main body 122 can be advanced and retreated from the state shown in Fig. 10 toward first curtain hanger 110 (i.e., to the left in Fig. 10) (see Fig. 12). In addition, a metal member 146 to which magnet 118 is detachably attached is provided on the surface of second curtain hanger 120 facing first curtain hanger 110.

[0048] Also, the main body 122 is provided with a detector (not shown) that detects that the first curtain hanger 110 has been attached to the second curtain hanger 120. Specifically, the detector includes a long and thin pin member that partially protrudes outward from the main body 122 toward the first curtain hanger 110, and when the first curtain hanger 110 is attached to the second curtain hanger 120 and the pin member is pushed into the main body 122, the detector detects that the first curtain hanger 110 has been attached to the second curtain hanger 120. Also, the connection portion 136 is normally housed inside the main body 122 as shown in Figures 9 and 10, but when the detector detects that the first curtain hanger 110 has been attached to the second curtain hanger 120, it extends toward the first curtain hanger 110 as shown in Figure 12. In addition, the length by which the connection portion 136 extends from the main body portion 122 is greater than the length of the first curtain hanger 110 in the longitudinal direction of the curtain rail 90. As a result, when the connection portion 136 extends toward the first curtain hanger 110 with the first curtain hanger 110 attached to the second curtain hanger 120, the attachment portion 150 is located farther from the second curtain hanger 120 than the first curtain hanger 110. In addition, when the connection portion 136 extends toward the first curtain hanger 110 and the detector no longer detects that the first curtain hanger 110 is attached to the second curtain hanger 120, the connection portion 136 moves toward the main body portion 122 as shown by the arrow in FIG. 14 and becomes housed inside the main body portion 122.

[0049] Next, the operation of such a curtain hanging device will be described with reference to FIGS.

[0050] FIG. 10 is a diagram showing a curtain unit when the first and second curtains are located on both sides of a window and the window is not covered by the first and second curtains. When an operator pulls the first and second curtains together toward the center of the window from this state to cover the window with the first and second curtains, the operator first pulls the first curtain to move the first curtain hanger 110 to the right along the curtain rail 90, and pulls the second curtain to move the second curtain hanger 120 to the left along the curtain rail 90. This brings the side edges of the first curtain and the second curtain close to each other. Also, as shown in FIG. 11, the magnet 118 of the first curtain hanger 110 sticks to the metal member 146 of the second curtain hanger 120, so that the first curtain hanger 110 is attached to the second curtain hanger 120.

[0051] When the detector detects that the first curtain hanger 110 has been attached to the second curtain hanger 120, the connection portion 136 extends toward the first curtain hanger 110 as shown in FIG. 12. This causes the through hole 152 of the attachment portion 150 to be located to the left of the hook portion 116 provided on the main body portion 112 of the first curtain hanger 110 in FIG. 12. Therefore, the third hanger that hangs a portion near the edge of the second curtain is located to the left of the first hanger that hangs a portion near the edge of the first curtain in FIG. 12. This causes the area between the side edge of the first curtain and the side edge of the second curtain to overlap, preventing a gap from occurring between the first and second curtains that are pulled together toward the center.

[0052] When opening the first and second curtains from the state shown in Fig. 12, the worker pulls the first curtain to the left and the second curtain to the right. Then, as shown by the arrows in Fig. 13, when the worker pulls the first curtain to the left and the second curtain to the right, the second curtain hanger 120 moves away from the first curtain hanger 110, and the detection unit no longer detects that the first curtain hanger 110 has been attached to the second curtain hanger 120, and the connection unit 136 moves toward the main body unit 122 and is housed inside the main body unit 122, as shown in Fig. 14. In this way, the first and second curtains can be opened to the left and right from the window.

[0053] According to the curtain hanging device and curtain unit shown in Figures 9 to 14, the second curtain hanger 120 is provided separately from the main body 122 and has an attachment part 150 to which a third hanging tool for hanging the second curtain can be attached, and a connection part 136 that connects the main body 122 and the attachment part 150 can be advanced and retreated from the main body 122. This makes it possible to prevent a gap from occurring in the central pulled-together part when the pair of left and right first and second curtains are pulled together toward the center of the window. Moreover, such a curtain hanging device and curtain unit can be applied to an existing curtain rail 90 that extends in a straight line.

[0054] Furthermore, with such a curtain hanging device and curtain unit, when the detector detects that the first curtain hanger 110 has been attached to the second curtain hanger 120, the connection part 136 automatically extends toward the first curtain hanger 110. Therefore, even if the worker does not perform the action of overlapping the first and second curtains, the attachment part 150 is automatically positioned farther from the second curtain hanger 120 than the first curtain hanger 110, so that the first and second curtains can be automatically overlapped, thereby reducing the labor of the worker.
