[0030] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0031] like Figure 1 As shown, the ring slider 1 of this embodiment is used to hang a window curtain 8 and can move along the axial direction of a curtain rail 9 and is configured to be detachable relative to the curtain rail 9.

[0032] In addition, the specific structure of the curtain 8 and the curtain rail 9 using the ring slider 1 is not particularly limited. The curtain 8 illustrated in the present embodiment includes a curtain 81 and a plurality of washers 82 provided at the upper end of the curtain 81. The curtain 8 is suspended and supported on the curtain rail 9 by the ring slider 1 passing through each washer 82. The curtain rail 9 illustrated in the present embodiment is a rod body with both ends fixed to the wall surface, such as a shower curtain rail.

[0033] [Structure of the Ring Slider 1]

[0034] Main reference Figure 2 Next, the structure of the ring slider 1 will be described.

[0035] The ring slider 1 is formed as an integral body by elastic materials such as synthetic resin, and comprises: a ring portion 2 having an opening 21 that can be opened and closed; a curtain holding portion 3 provided on the ring portion 2; a first leg portion 41 and a second leg portion 42 that open and close the opening 21 of the ring portion 2; and a handle portion 5 provided on the ring portion 2.

[0036] The ring portion 2 is extended in a ring shape so as to form a through hole 20 through which the curtain rail 9 passes. The ring portion 2 has an opening 21 formed by cutting out a part of the ring shape of the ring portion 2. In other words, the ring portion 2 has a pair of opening ends 22 and 23, and the pair of opening ends 22 and 23 form the opening 21 connected to the through hole 20. In addition, the ring portion 2 can be elastically deformed so that the pair of opening ends 22 and 23 are close to each other, so that the opening 21 is closed (see Figure 3 ).

[0037] As a specific structure, the ring part 2 has the following parts: a ring main body part 24, which is arranged along a circle or an ellipse centered on the central axis C; and a curved part 25, which is curved outward from the ring main body part 24. The ring main body part 24 is formed with an inner peripheral surface 241 that can abut against the curtain rail 9. The range of the ring main body part 24 in the ring part 2 is divided by the curved part 25.

[0038] Hereinafter, the direction along the central axis C of the ring portion 2 is referred to as the axial direction, and the direction orthogonal to the central axis C is referred to as the radial direction. In addition, the central axis C of the ring portion 2 in the present embodiment can be determined as the center of the inner peripheral surface 241 of the ring body portion 24. In addition, the ring portion 2 in the present embodiment extends along a circle, and therefore, the extending direction of the ring portion 2 is sometimes referred to as the circumferential direction.

[0039] The cross-sectional shape orthogonal to the circumferential direction of the ring portion 2 is not particularly limited, and may be either circular or rectangular. In addition, the radial and axial dimensions of the ring portion 2 are not particularly limited. In the present embodiment, the radial and axial dimensions of the ring portion 2 are set so that the ring portion 2 can pass through the gasket 82 of the curtain 8.

[0040] The curtain holding portion 3 is constituted by the bent portion 25 of the ring portion 2. That is, the curtain holding portion 3 is constituted as a part of the ring portion 2 in the circumferential direction, and a recessed portion 251 is formed that is recessed relative to the inner circumferential surface 241 of the ring body portion 24. The curtain holding portion 3 can maintain the arrangement of the gasket 82 in the ring portion 2 while the gasket 82 of the curtain 8 is penetrated.

[0041] The curtain holding portion 3 is provided at a position of the ring portion 2 that is separated from the opening end portions 22 and 23 of the ring portion 2 in the circumferential direction and is excluding a portion facing the opening portion 21 .

[0042] In addition, if Figure 3 As shown in FIG. 1 , the first direction R1, which is the direction from the central axis C of the ring portion 2 toward the opening portion 21 in the closed state, and the second direction R2, which is the direction from the central axis C of the ring portion 2 toward the curtain holding portion 3, intersect each other. For example, the first direction R1 and the second direction R2 preferably intersect at an angle of 60 to 120 degrees, and more preferably at an angle of 90 degrees. In other words, it is preferred that the opening portion 21 of the ring portion 2 be arranged on one side in the horizontal direction relative to the central axis C when the curtain holding portion 3 is arranged at the lower side in the vertical direction relative to the central axis C.

[0043] In addition, the above-mentioned first direction R1 can be defined as a direction passing through the central axis C and the intersection of the pair of open end portions 22 and 23 of the ring portion 2 when the ring portion 2 is observed from the axial direction. In addition, the above-mentioned second direction R2 can be defined as a direction passing through the central axis C and the holding position of the curtain 8 in the curtain holding portion 3 (in the present embodiment, the central portion in the circumferential direction of the curtain holding portion 3) when the ring portion 2 is observed from the axial direction.

[0044] The first leg portion 41 protrudes radially outward from the open end portion 22 of the ring portion 2, and the second leg portion 42 protrudes radially outward from the open end portion 23 of the ring portion 2. The first leg portion 41 and the second leg portion 42 are bent so as to be farther away from each other as they go radially outward, and when the ring portion 2 is elastically deformed, the first leg portion 41 and the second leg portion 42 can be twisted together in a "twisted configuration".

[0045] In this embodiment, when the first leg 41 and the second leg 42 are twisted, Figure 3 As shown, the base end portion 412 of the first leg portion 41 abuts against one side (the back side of the paper) in the axial direction relative to the opening end portion 23 of the ring portion 2. In addition, the first leg portion 41 and the second leg portion 42 cross in an alternating manner in the axial direction, and the top end portion 411 of the first leg portion 41 abuts against the other side (the front side of the paper) in the axial direction relative to the top end portion 421 of the second leg portion 42.

[0046] The ring slider 1 of this embodiment has a groove structure suitable for the above-mentioned twisted arrangement composed of the first leg portion 41 and the second leg portion 42. Figure 4 and Figure 5 In addition, Figure 4 and Figure 5 , for illustration, a center line M of the ring slider 1 in the axial direction is shown.

[0047] like Figure 4 As shown, the first leg portion 41 includes: a top groove portion 6A, which is arranged to the top end portion 411; a base end groove portion 7A, which is arranged to the base end portion 412; and an intermediate portion 413, which is arranged between the top groove portion 6A and the base end groove portion 7A in the extending direction of the first leg portion 41. The top groove portion 6A and the base end groove portion 7A open to the opposite sides of the axial direction.

[0048] The top groove portion 6A has a groove depth D1 corresponding to half the thickness of the first leg portion 41 in the axial direction, and penetrates the first leg portion 41 along the width direction of the first leg portion 41 which is orthogonal to the extension direction and the axial direction of the first leg portion 41. Similarly, the base end groove portion 7A has a groove depth D2 corresponding to half the thickness of the first leg portion 41 in the axial direction, and penetrates the first leg portion 41 along the width direction of the first leg portion 41. The wall portion of the top groove portion 6A located on the top side of the first leg portion 41 may be absent. The groove width of the base end groove portion 7A is greater than the width of the ring portion 2 in the directions orthogonal to the extension direction and the axial direction of the ring portion 2.

[0049] like Figure 5 As shown, the second leg portion 42 has a top groove portion 6B arranged at the top end portion 421, and the opening end portion 23 of the ring portion 2 has a base end groove portion 7B. In addition, the second leg portion 42 has an intermediate portion 423 arranged between the top groove portion 6B and the base end groove portion 7B in the extending direction of the second leg portion 42. The top groove portion 6B and the base end groove portion 7B open to the opposite sides of each other in the axial direction.

[0050] The top groove portion 6B has a groove depth D3 corresponding to half the thickness of the second leg portion 42 in the axial direction, and penetrates the second leg portion 42 along the width direction of the second leg portion 42 which is orthogonal to the extension direction and the axial direction of the second leg portion 42. Similarly, the base end groove portion 7B has a groove depth D4 corresponding to half the thickness of the ring portion 2 in the axial direction, and penetrates the ring portion 2 along the width direction of the ring portion 2. The wall portion of the top groove portion 6B located on the top side of the second leg portion 42 may be absent. The groove width of the base end groove portion 7B is greater than the width of the first leg portion 41.

[0051] In addition, the top groove 6A of the first leg 41 and the top groove 6B of the second leg 42 are open to the opposite sides of the axial direction, and the base end groove 7A of the first leg 41 and the base end groove 7B of the ring 2 are open to the opposite directions in the axial direction.

[0052] When the first leg 41 and the second leg 42 are twisted, Figure 3 As shown, the base end groove 7A of the first leg portion 41 and the base end groove 7B of the ring portion 2 are axially fitted to each other, and the distal end groove 6A of the first leg portion 41 and the distal end groove 6B of the ring portion 2 are axially fitted to each other.

[0053] At this time, the wall surface of the base end groove portion 7A of the first leg portion 41 is engaged with the opening end portion 23 of the ring portion 2 in the radial direction, the top end portion 411 of the first leg portion 41 is engaged with the top end portion 421 of the second leg portion 42 in the axial direction, and the middle portion 413 of the first leg portion 41 is engaged with the middle portion 423 of the second leg portion 42 in the width direction of the opening portion 21. That is, the first leg portion 41 and the second leg portion 42 can achieve engagement in three directions of the radial direction, the axial direction, and the width direction of the opening portion 21 of the ring portion 2, and lock the closed state of the opening portion 21 of the ring portion 2.

[0054] like Figure 2 As shown, the handle portion 5 is formed integrally with the ring portion 2, and protrudes radially outward from a portion of the ring portion 2 that is opposite to the opening portion 21. Specifically, the handle portion 5 includes: a pair of side portions 511, 512 that are connected to the outer peripheral surface 242 of the ring body portion 24 and extend in the axial direction; an R-shaped corner portion 52 that is formed between the pair of side portions 511, 512, and a pair of plane portions 531, 532 that are orthogonal to the axial direction. When viewed along the axial direction, the pair of side portions 511, 512 are arranged on different lines T1 and T2 that are connected to the outer peripheral surface 242 of the ring body portion 24. The corner portion 52 preferably has an angle of, for example, 90 degrees or more as the angle formed by the lines T1 and T2.

[0055] [How to install the ring slider]

[0056] An example of a method of mounting the ring slider 1 according to the present embodiment will be described.

[0057] First, the operator installs the curtain 8 on Figure 2 The curtain holding part 3 of the ring slider 1 shown (curtain mounting process). At this time, the operator inserts the first leg 41 into the washer 82 of the curtain 8 and moves the washer 82 along the extending direction of the ring part 2 to arrange the curtain 8 on the curtain holding part 3.

[0058] Next, after the operator holds the handle 5 with one hand, Figure 6As shown by the arrow A1, the opening 21 of the ring 2 is pushed upward in the vertical direction relative to the curtain rail 9 (pushing process). At this time, the first leg 41 and the second leg 42 guide the curtain rail 9 toward the opening 21 of the ring 2. In addition, the ring 2 is pushed by the curtain rail 9 via the first leg 41 and the second leg 42, and elastically deforms in a manner that the opening 21 widens. As a result, the curtain rail 9 passes through the opening 21 and is inserted into the ring 2. In addition, during the pushing process, the curtain 8 held by the curtain holding part 3 is arranged at a position separated from the opening 21 so as not to cover the opening 21 of the ring 2.

[0059] Next, if Figure 7 As shown by the arrow A2, the ring slider 1 is rotated (rotation process). However, the operator's force is not required for the rotation of the ring slider 1. That is, if the operator takes his hand off the handle 5, a rotation torque centered on the curtain rail 9 is applied to the ring slider 1 due to the load of the curtain 8 held by the curtain holding part 3. As a result, the ring slider 1 rotates centered on the curtain rail 9. At this time, the curtain rail 9 slides relative to the inner circumferential surface 241 of the ring part 2.

[0060] If the rotation of the ring slider 1 is completed, Figure 8 As shown, the curtain holding portion 3 is arranged on the lower side in the vertical direction with respect to the curtain rail 9 , and the opening 21 of the ring portion 2 is arranged on one side in the horizontal direction with respect to the curtain rail 9 .

[0061] Afterwards, if Figure 8 As shown by arrow A3, the operator twists the first leg 41 and the second leg 42. Thus, the first leg 41 and the second leg 42 are maintained in the twisted configuration described above, and the closed state of the opening 21 of the ring 2 is locked.

[0062] Through the above steps, the installation of the ring slider 1 relative to the curtain rail 9 is completed.

[0063] In addition, when replacing the curtain 8, etc., when removing the ring slider 1 from the curtain rail 9, the above-mentioned ring slider 1 installation method can be reversed. For example, after the opening 21 of the ring part 2 is opened by operating the first leg part 41 and the second leg part 42, the handle part 5 is pulled downward in the vertical direction. In this way, the curtain rail 9 can pass through the opening 21 of the ring part 2, and the ring slider 1 can be removed from the curtain rail 9.

[0064] [Effects of this embodiment]

[0065] As described above, the ring slider 1 of the present embodiment includes: a ring portion 2 extending in a ring shape so as to form a through hole 20 for the curtain rail 9 to pass through; and a curtain holding portion 3 provided on the ring portion 2, the ring portion 2 having a pair of opening end portions 22, 23, the pair of opening end portions 22, 23 forming an opening portion 21 communicating with the through hole 20, the opening portion 21 of the ring portion 2 being opened and closed by elastic deformation of the ring portion 2, and a first direction R1 being a direction from the central axis C of the ring portion 2 toward the opening portion 21 in a closed state and a second direction R2 being a direction from the central axis C of the ring portion 2 toward the curtain holding portion 3 intersect with each other.

[0066] In the above structure, the curtain rail 9 can be inserted into or removed from the ring part 2 through the opening 21 of the ring part 2, so that the ring slider 1 can be attached to or detached from the curtain rail 9. In addition, when the ring slider 1 is attached or detached, the curtain 8 attached to the curtain holding part 3 is unlikely to interfere with the opening 21 of the ring part 2, so the detachment operation of the ring slider 1 to the curtain rail 9 becomes easy. In addition, after the ring slider 1 is attached to the curtain rail 9, in a state where the weight of the curtain 8 is applied to the curtain holding part 3, it is possible to avoid that the opening 21 of the ring part 2 is arranged on the upper side in the vertical direction relative to the curtain rail 9. Therefore, it is possible to suppress the ring slider 1 from falling off from the curtain rail 9 without a structure for firmly closing the opening 21 of the ring part 2. Therefore, the ease of detachment operation of the ring slider 1 is not impaired.

[0067] Therefore, according to the ring slider 1 of the present embodiment, even when the curtain 8 is attached, the attachment and detachment work with respect to the curtain rail 9 can be easily performed.

[0068] In the present embodiment, the curtain holding portion 3 is provided at a portion of the ring portion 2 other than the portion facing the opening portion 21 , spaced apart from the pair of opening end portions 22 , 23 in the extending direction of the ring portion 2 .

[0069] According to the above structure, even if the opening 21 of the ring part 2 is in an open state, the ring slider 1 can be prevented from falling off from the curtain rail 9. For example, the ring slider 1 can be prevented from accidentally falling off during the installation and removal operation of the ring slider 1 relative to the curtain rail 9, so the operator can temporarily remove the ring slider 1. Therefore, the installation operation of the ring slider 1 relative to the curtain rail 9 becomes easier.

[0070] In the present embodiment, the curtain holding portion 3 is configured as the bent portion 25 which is a part of the ring portion 2 , and a recessed portion 251 is formed which is recessed relative to the inner peripheral surface 241 of the ring portion 2 except for the bent portion 25 .

[0071] In the above structure, the curtain holding part 3 can hold the curtain 8 by the gasket 82 which penetrates the curtain 8. That is, the ring slider 1 can directly hold the curtain 8 without using other hooks etc. Thus, the structure of the curtain holding part 3 can be simplified.

[0072] The ring slider 1 of the present embodiment further includes a handle portion 5 provided on the ring portion 2 , and the handle portion 5 protrudes toward the outside of the ring portion 2 from a portion of the ring portion 2 facing the opening portion 21 .

[0073] In the above-mentioned structure, when attaching and detaching the ring slider 1 to the curtain rail 9, the operator can appropriately apply force to the ring portion 2. Therefore, the attachment work of the ring slider 1 to the curtain rail 9 becomes easier.

[0074] In this embodiment, the handle portion 5 has: a pair of side portions 511 and 512 arranged on different lines T1 and T2 connected to the outer peripheral surface 242 of the ring portion 2; and a corner portion 52 formed between the pair of side portions 511 and 512.

[0075] According to the above configuration, the handle portion 5 can strengthen the elastic force when the opening portion 21 of the ring portion 2 is opened and closed.

[0076] In the present embodiment, when the curtain holding portion 3 is arranged vertically downward with respect to the central axis C, the opening 21 of the ring portion 2 is arranged on one side in the horizontal direction with respect to the central axis C.

[0077] According to the above configuration, it is possible to appropriately achieve both suppression of interference of the curtain 8 with the attachment and detachment work of the ring slider 1 and suppression of the ring slider 1 from falling off.

[0078] In the present embodiment, the inner peripheral surface 241 of the ring portion 2 is continuously curved at least from the opening 21 to a portion facing the curtain holding portion 3 .

[0079] According to the above-mentioned structure, when the ring slider 1 is attached or detached, the rotation of the ring part 2 relative to the curtain rail 9 is not hindered. Therefore, the attachment or detachment of the ring slider 1 can be easily performed.

[0080] The ring slider 1 of this embodiment further includes a first leg portion 41 and a second leg portion 42 extending from the pair of opening ends 22 and 23 of the ring portion 2 to the side opposite to the through hole 20 , and the first leg portion 41 and the second leg portion 42 are twisted relative to each other by elastic deformation of the ring portion 2 .

[0081] In the above structure, the opening 21 of the ring 2 can be opened and closed by operating the first leg 41 and the second leg 42. In addition, the operator can operate the first leg 41 and the second leg 42 with one hand.

[0082] In the prior art such as the above-mentioned Patent Document 1, the pair of opening ends of the ring portion is configured to have both the closing function of closing the opening of the ring portion and the curtain holding function, so the structure is complicated. On the other hand, in the present embodiment, the first leg portion 41 and the second leg portion 42 that close the opening 21 of the ring portion 2 and the curtain holding portion 3 are respectively configured, so the structures of the two can be simplified and the strength can be improved.

[0083] In the present embodiment, the base end portion 412 of the first leg portion 41 and the open end portion 23 of the ring portion 2 connected to the second leg portion 42 have a base end groove portion 7A and a base end groove portion 7B that are open in an axial direction opposite to each other. When the first leg portion 41 and the second leg portion 42 are twistedly arranged, the base end groove portion 7A of the first leg portion 41 and the base end groove portion 7B of the open end portion 23 are axially engaged with each other.

[0084] In such a structure, when the first leg portion 41 and the second leg portion 42 are twistedly arranged, it is possible to appropriately maintain the closed state of the opening portion 21 while suppressing an increase in the axial thickness of the ring slider 1 .

[0085] In the present embodiment, the top end portions 411 and 421 of the first leg portion 41 and the second leg portion 42 respectively have top end groove portions 6A and 6B opening in opposite directions in the axial direction of the ring portion 2. When the first leg portion 41 and the second leg portion 42 are twistedly arranged, the top end groove portion 6A of the first leg portion 41 and the top end groove portion 6B of the second leg portion 42 are axially interlocked with each other.

[0086] In the above structure, when the first leg portion 41 and the second leg portion 42 are twisted, the thickness increase in the axial direction of the ring slider 1 can be suppressed, and the state in which the opening portion 21 is closed can be appropriately maintained.

[0087] [Modifications]

[0088] In the above embodiment, the ring slider 1 is attached to the curtain 8 by passing through the gasket 82, but the present invention is not limited thereto. For example, the ring slider 1 may be attached to any type of curtain by means of other members such as a hook.
