Description

[Technical Field]

[0001] The present invention relates to a tassel fastener, a curtain tassel, and a curtain set. [Background technology]

[0002] When not in use, curtains installed indoors are tied up by wrapping band-shaped members called curtain tassels around them. Curtain tassels generally have ring-shaped members on both ends, and the curtain tassels are wrapped around the curtains and secured by hooking the ring-shaped members on both ends of the curtain tassels onto curtain hooks fixed to the edge of the window frame. Connectors for such curtain tassels that can be attached to both ends of curtain tassels are disclosed, for example, in Patent Documents 1 and 2.

[0003] Meanwhile, in facilities such as hospitals, curtains are installed to partition indoor spaces, enclosing personal spaces including beds or separating personal spaces. Such partition curtains are often hung from curtain rails fixed or supported on the ceiling surface of the room, and are often pulled to one side when not in use. However, since fringe hooks or the like are often not installed on the walls of facilities corresponding to the installation locations of the curtains, partition curtains are bundled in the following manners, for example, as shown in (1) and (2). (1) Curtain tassels with hook-and-loop fasteners are pre-sewn onto the partition curtains, and the hook-and-loop fasteners are used to form the curtain tassels into a loop to hold the curtains together. (2) Tie the curtains together using a separate fastener (such as an elastic band with clip-like components on both ends). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-6281 [Patent Document 2] Japanese Patent Application Publication No. 2018-164747 Summary of the Invention [Problem to be solved by the invention]

[0005] However, as mentioned in (1) above, sewing curtain tassels to curtains and sewing hook-and-loop fasteners to curtain tassels is extremely time-consuming. Also, many room divider curtains do not originally have curtain tassels, and preparing a separate fastener like the one mentioned in (2) above is troublesome and costly, makes bundling the curtains difficult, and is unsightly.

[0006] Furthermore, the conventional curtain tassel connectors proposed in Patent Documents 1 and 2 are designed to be hooked onto a tassel holder, making them difficult to apply when a hooking device such as a tassel holder is not installed in the required location in the room.

[0007] In view of the above circumstances, the present invention aims to provide a curtain tassel equipped with a fastening device that allows curtains to be easily bound together without a tassel hook, a tassel fastening device for realizing this, and a curtain set. [Means for solving the problem]

[0008] The present invention First The tassel fastening device constitutes at least one end of a curtain tassel whose both ends are connectable, and is capable of fastening a fastened member provided at the other end of the curtain tassel, and comprises an attachment part that can be attached to the end of a band-shaped body that constitutes the main body of the curtain tassel, and a hook part that extends from the attachment part and has a hook-shaped part that can fasten the fastened member; a detachment prevention portion protruding from the attachment portion toward the hook-shaped portion; Equipped with The hook portion and the release prevention portion define a holding space capable of holding the member to be locked. It is characterized by: The second tassel fastening device of the present invention is a tassel fastening device that forms at least one end of a curtain tassel whose both ends are connectable and that can fasten a fastening member provided at the other end of the curtain tassel, and is characterized in that it comprises an attachment portion that can be attached to the end of a band-shaped body that forms the main body of the curtain tassel, and a hook portion that extends from the attachment portion and has a hook-shaped portion that can fasten the fastening member, and the hook portion has an axis portion that protrudes linearly from the attachment portion, and the two hook-shaped portions extend in opposite directions from the tip of the axis portion. The third tassel fastening device of the present invention is a tassel fastening device that is a resin molded product that forms at least one end of a curtain tassel whose both ends are connectable and can fasten a fastening member provided at the other end of the curtain tassel, and is characterized in that it comprises an attachment portion that can be attached to the end of a band-shaped body that forms the main body of the curtain tassel, and a hook portion that extends from the attachment portion and has a hook-shaped portion that can fasten the fastening member, and the attachment portion has a plate-shaped portion that is thinner than the hook portion, and the plate-shaped portion and the band-shaped body can be sewn together.

[0009] Common to the first to third tassel fastenersAccording to this configuration, the curtain tassel includes an attachment portion that can be attached to the end of the belt-shaped body that constitutes the main body of the curtain tassel, and a hook portion that extends from the attachment portion and has a hook-shaped portion that can engage the interlocking member, so that the interlocking member provided at the other end of the curtain tassel can be engaged as at least one end member that constitutes the curtain tassel.As a result, both ends of the curtain tassel can be connected, and curtains can be easily bundled without a tassel hook. According to the configuration of the first tassel fastening device, in addition to the effects of the common configuration described above, the anti-detachment portion that protrudes from the attachment portion toward the hook-shaped portion defines a holding space capable of holding the fastened member together with the hook portion, so that the held fastened member is less likely to come off easily. According to the configuration of the second tassel fastening device, in addition to the effects of the above common configuration, it is provided with two hook-shaped portions on both the left and right sides of the shaft portion, and holding spaces are located on both the left and right sides of the shaft portion, so either of the left or right hook-shaped portions can be fastened to the fastened member, making it easy to fasten the fastened member. The third tassel fastener configuration, in addition to the effects of the common configuration described above, makes it easy to attach the attachment portion to the band-shaped member that constitutes the main body of the curtain tassel easily and securely. It also facilitates a configuration in which the hook-shaped portion of the hook portion deforms outward and opens when a tensile load of a predetermined value or greater is applied to the hook-shaped portion, making it easy to achieve both the strength required for a fastener and a safety function in which the fastened member is released from the holding space when a tensile load of a predetermined value or greater is applied.

[0010] The curtain tassel according to the present invention is characterized in that the above-mentioned tassel fasteners are attached to both ends of a band-shaped body.

[0011] With this configuration, the tassel fasteners are attached to both ends of the belt, so the ends of the curtain tassels can be fastened together and can be easily connected from either side. This makes it even easier to bundle curtains in places where there are no tassel hooks.

[0012] Furthermore, the curtain set of the present invention is a curtain set comprising the above-mentioned curtain tassel and a curtain, characterized in that the curtain, when installed, has another engaging member of the curtain tassel at at least one of both widthwise ends and at a predetermined height position where the curtain tassel is attached.

[0013] With this configuration, even when the curtain is in use, one end of the curtain tassel can be fastened to at least one end of the curtain in the width direction, making it easy to quickly and easily bundle the curtain even in places where there are no tassels. Also, since another fastening member is provided at a predetermined height position on the curtain, it is possible to prevent the curtain tassel from shifting up and down when the curtain is bundled, making it easy to position the curtain tassel at the predetermined height.

[0014] Preferred embodiments of the present invention will be described below, but the scope of the present invention is not limited to the preferred embodiments described below.

[0019] In the tassel fastening device according to the present invention, it is preferable that the fastening surface of the hook-shaped portion of the fastening member includes at least a partially curved surface.

[0020] With this configuration, the locked member can move easily within the holding space of the tassel locking device, making it easy to guide the locked member to the locking position of the tassel locking device, and also to guide the locked member to a position where it can be easily removed from the tassel locking device.

[0021] The present invention First and second The tassel fastener is preferably a resin molded product.

[0022] This configuration makes it easy to configure the hook-shaped portion of the hook part to deform outward and open when a tensile load of a predetermined value or greater is applied to the hook-shaped portion of the hook part, making it easy to achieve both the strength required for a fastener and a safety function in which the fastened member is released from the holding space when a tensile load of a predetermined value or greater is applied.Furthermore, the fastener for a tassel is easy to manufacture.

[0025] In the tassel fastener according to the present invention, the resin molded product preferably contains high-density polyethylene as a main component.

[0026] This configuration makes it easier to achieve both the strength required for the locking tool and the safety function of releasing the locked member from the retaining space when a tensile load equal to or greater than a predetermined value is applied.

[0027] Further features and advantages of the present invention will become more apparent from the following description of exemplary and non-limiting embodiments, which is given with reference to the drawings. [Brief explanation of the drawings]

[0028] [Figure 1] FIG. 1 shows a curtain tassel according to an embodiment. [Figure 2]1 is a plan view of a tassel fastener according to an embodiment; [Figure 3] FIG. 1 is a right side view of a tassel fastener according to an embodiment; [Figure 4] 1 is a diagram illustrating a method of using a curtain tassel according to an embodiment; [Figure 5] 1 is a diagram illustrating a method of using a curtain tassel according to an embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0029] Embodiments of a curtain tassel and a tassel fastener according to the present invention will be described with reference to Figures 1 to 5. In the following, an example will be described in which the curtain tassel according to the present invention is applied to a curtain tassel 10 that fastens a partition curtain 50 in a facility or the like.

[0030] As shown in FIG. 1 , the curtain tassel 10 is composed of a strip-shaped curtain tassel body 10A (an example of a strip-shaped body) that forms the main body of the curtain tassel 10, and two tassel fasteners 1 that form both ends of the curtain tassel 10. In this embodiment, the same tassel fasteners 1 are attached to both ends of the curtain tassel body 10A, with the tassel fastener 1 at one end of the curtain tassel 10 functioning as a fastening member and the tassel fastener 1 at the other end functioning as a fastened member. The curtain tassel 10 according to this embodiment can be connected at both ends by fastening the fastened member at the other end of the curtain tassel 10 with the fastening member at one end of the curtain tassel 10. In this way, the curtain tassel 10 forms a ring-shaped structure as shown in FIG. 5 and can be used to tie up a curtain 50 hanging in a room when not in use.

[0031] [Tassel fastener] A plan view of the tassel fastener 1 is shown in Fig. 2, and a right side view of Fig. 2 is shown in Fig. 3. As shown in Figs. 2 and 3, the tassel fastener 1 comprises an attachment portion 2 that can be attached to the curtain tassel body 10A, and a hook portion 3 that extends from the attachment portion 2 and has a hook-shaped portion 31 that can fasten a fastening member (in this embodiment, the tassel fastener 1 at the other end of the curtain tassel 10). The bottom view of the tassel fastener 1 is the same as the plan view, and the left side view is the same as the right side view. In the following description, the surface direction of the tassel fastener 1 is the direction of the plane formed by the X-axis and Y-axis shown in Fig. 2, and the Z-axis direction shown in Fig. 3 is the thickness direction of the tassel fastener 1.

[0032] The tassel fastener 1 according to this embodiment further includes a release prevention portion 5 that protrudes from the attachment portion 2 toward the hook-shaped portion 31. The hook portion 3 and the release prevention portion 5 define a holding space 4 capable of holding a fastened member. The release prevention portion 5 prevents the fastened member held in the holding space 4 from easily coming off. The tassel fastener 1 according to this embodiment is composed of a single resin molded product.

[0033] The mounting portion 2 of the tassel fastener 1 according to this embodiment is planar and has a thin plate-like portion 21 and a base end portion 22 that is connected to the plate-like portion 21 and is thicker than the plate-like portion 21. The base end portion 22 is configured to have a length in the Y-axis direction that is shorter than the plate-like portion 21. The plate-like portion 21 of the mounting portion 2 according to this embodiment is thinner than the hook portion 3 and is configured so that it can be sewn to the curtain tassel body 10A. The base end portion 22 of the mounting portion 2 according to this embodiment is located at the boundary between the plate-like portion 21 and the hook portion 3 and the detachment prevention portion 5. The base end portion 22 is the portion against which the end of the curtain tassel body 10A is abutted when the mounting portion 2 of the tassel fastener 1 is attached to the curtain tassel body 10A.

[0034] The hook portion 3 has a hook-shaped portion 31 that can lock a member to be locked. The member to be locked of the tassel fastener 1 according to this embodiment may be the tassel fastener 1 provided at the other end of the curtain tassel 10 as described above, or may be another member to be locked, such as a looped string 51 provided on a curtain 50, which will be described later.

[0035] The hook portion 3 according to this embodiment has an axial portion 32 that protrudes linearly from the mounting portion 2, and two hook-shaped portions 31 that extend from the tip of the axial portion 32 to opposite sides in the X-axis direction. The hook portion 3 also has an arc-shaped recessed portion 33 on the tip side of the axial portion 32. The hook portion 3, together with the release prevention portion 5, defines a holding space 4 that can hold a member to be locked.

[0036] The slippage prevention portion 5 according to this embodiment protrudes from the base end portion 22 of the attachment portion 2 toward the hook-shaped portion 31, generally perpendicular to the Y-axis direction, and defines the retaining space 4 together with the hook portion 3. Specifically, in the tassel fastener 1 according to this embodiment, the tip 31A of the hook-shaped portion 31 of the hook portion 3 is located farther from the shaft portion 32 than the tip 5A of the slippage prevention portion 5. This makes it easier for the hook-shaped portion 31 to fasten the member to be fastened. Particularly when the member to be fastened is another tassel fastener 1, it is easy to guide the hook-shaped portion 31 to the fastening position. Furthermore, the tip 31A of the hook-shaped portion 31 of the hook portion 3 and the tip 5A of the slippage prevention portion 5 do not abut, forming a gap. In other words, the retaining space 4 has an opening 41. In other words, hook-shaped portion 31 of hook part 3 extends from the tip of shaft portion 32, and tip 31A extends to a position beyond tip 5A of removal prevention part 5. When viewing tassel fastener 1 of this embodiment from the side, as shown in Fig. 3, tip 31A of hook-shaped portion 31 of hook part 3 and tip 5A of removal prevention part 5 are positioned on approximately the same straight line. However, the configuration of the side is not limited to Fig. 3, and tip 31A of hook-shaped portion 31 may be positioned below tip 5A of removal prevention part 5, or tip 31A of hook-shaped portion 31 may be positioned above tip 5A of removal prevention part 5 in Fig. 3.

[0037] In this embodiment, the locking surface of the hook-shaped portion 31 of the hook section 3 for the locked member includes at least a partially curved surface. In this embodiment, the inwardly curved thickness surface of the hook-shaped portion 31 of the hook section 3 and the thickness surface of the shaft portion 32 are connected to form an arc-like shape. As a result, the locked member held in the retaining space 4 is less likely to get caught within the retaining space 4 and is more likely to move within the retaining space 4. This makes it easier to guide the locked member to the hook-shaped portion 31, which is the locking position of the tassel fastener 1, and also to a position where the locked member can be easily released from the tassel fastener 1. Note that in this embodiment, the thickness surfaces of the boundary between the release prevention portion 5 and the base end portion 22 and the boundary between the base end portion 22 and the shaft portion 32 are also arc-shaped, making it even more difficult for the locked member to get caught within the retaining space 4. Furthermore, in this embodiment, the tip 31A of the hook-shaped portion 31 of the hook portion 3 and the tip 5A of the release prevention portion 5 are also formed in an arc shape (e.g., approximately semicircular), making it easy to smoothly lock and release the locked member.

[0038] In this embodiment, as shown in the right side view of FIG. 3 , the hook portion 3 (hook-shaped portion 31, shaft portion 32), the slippage prevention portion 5, and the base end portion 22 of the attachment portion 2 have substantially the same thickness. The thickness of these portions is presumably related to the balance with the hardness of the resin forming the tassel fastener 1, and is not particularly limited, but may be 2 to 5 mm (e.g., 3 mm ± 0.5 mm). This thickness facilitates obtaining sufficient strength as a fastener. Meanwhile, the thickness of the plate-like portion 21 of the attachment portion 2 is preferably 0.5 to 0.9 mm, although this depends on the balance with the hardness of the resin forming the plate-like portion 21. Setting the thickness of the plate-like portion 21 to 0.5 to 0.9 mm facilitates the passage of a sewing needle when sewing the plate-like portion 21 to the curtain tassel body 10A. Furthermore, the plate-like portion 21 is less likely to tear or break after sewing. When the plate-like portion 21 is made of a resin containing a polyethylene-based resin as a main component, the thickness is more preferably 0.6 to 0.8 mm, and particularly preferably 0.65 to 0.75 mm.

[0039] In this embodiment, the width of the plate-shaped portion 21 and base end portion 22 of the attachment portion 2 along the X-axis direction and the outermost width of the two hook-shaped portions 31 of the hook portion 3 along the X-axis direction are approximately the same. The width of the plate-shaped portion 21 and base end portion 22 of the attachment portion 2 along the X-axis direction is presumably related to the balance with the hardness of the resin forming the tassel fastener 1, and is not limited thereto, but is preferably, for example, 25 to 35 mm. If the width of the plate-shaped portion 21 and base end portion 22 of the attachment portion 2 along the X-axis direction is 25 to 35 mm, it will easily fit within the width dimension of a typical curtain tassel body 10A, making it easy to sew the attachment portion 2 to the end of the curtain tassel body 10A. It is more preferable that the width of the plate-shaped portion 21 and base end portion 22 of the attachment portion 2 along the X-axis direction be 28 to 33 mm. Furthermore, the length of the plate-like portion 21 of the attachment portion 2 along the Y-axis direction is presumably related to the balance with the hardness of the resin forming the tassel fastener 1, and is not limited thereto, but a length of 10 to 20 mm is preferable for ease of sewing to the end of the curtain tassel body 10A. A length of the plate-like portion 21 of the attachment portion 2 along the Y-axis direction of 12 to 14 mm is even more preferable.

[0040] 2, the minimum width W1 of the hook-shaped portion 31 at a portion of the hook portion 3 that does not have the recessed portion 33 is smaller than the minimum width W2 of the shaft portion 32. Furthermore, the minimum width W3 of the hook-shaped portion 31 at a portion of the hook portion 3 that has the recessed portion 33 is smaller than the minimum width W1. This configuration facilitates a structure in which the hook-shaped portion 31 easily opens when a tensile load equal to or greater than a predetermined value is applied in the opening direction of the hook-shaped portion 31 (Y-axis direction).

[0041] Furthermore, in this embodiment, as shown in the plan view of FIG. 2 , the width W4 of the slippage prevention portion 5 is smaller than the minimum widths W1 to W3 of each portion of the hook portion 3. This configuration facilitates making the slippage prevention portion 5 more flexible than the hook portion 3. In the tassel fastener 1 according to this embodiment, the slippage prevention portion 5 is positioned so as to close the space defined by the hook portion 3 (hook-shaped portion 31, shaft portion 32) and the attachment portion 2 (base end portion 22) from the inside, like a valve. Therefore, when a member to be locked is pushed into the holding space 4, a force is naturally applied to the slippage prevention portion 5 so that it tilts inward into the holding space 4, facilitating the insertion of the member to be locked into the holding space 4 through the opening 41. On the other hand, when the member to be locked attempts to be removed from the holding space 4, the member to be locked is caught near the tip 31A of the hook-shaped portion 31, and the slippage prevention portion 5 is not easily subjected to a force that tilts it outward from the holding space 4, making it difficult for the member to be locked to be removed. In this way, the tassel fastener 1 according to this embodiment makes it easy to push a fastened member into the holding space 4, but makes it difficult for the held fastened member to come out of the holding space 4. Also, in this embodiment, the opening width of the opening 41 of the holding space 4 in the plan view of Fig. 2 (i.e., the shortest distance between the hook-shaped portion 31 and the slippage prevention portion 5) is smaller than the width (minimum widths W1 and W3) of the hook-shaped portion 31 of the hook portion 3. With this configuration, when another tassel fastener 1 is used as the fastened member, the hook-shaped portion 31 of the fastened member does not easily come out of the opening 41.

[0042] As described above, the tassel fastener 1 according to this embodiment is a resin molded product. The tassel fastener 1 according to this embodiment is preferably formed from a resin material containing, as a main component, polyethylene resins such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE), polypropylene resin, nylon resin, polycarbonate resin, thermoplastic polyurethane elastomer (TPU), polyvinyl chloride resin (PVC), elastomer resin, ethylene-vinyl acetate copolymer resin (EVA), polyacetal resin, and fluororesin. Forming the tassel fastener 1 from such a resin material facilitates the flexible configuration of the slippage prevention portion 5 of the tassel fastener 1, and facilitates the configuration of the hook-shaped portion 31 of the hook portion 3 to deform (preferably plastically deform) when a tensile load equal to or greater than a predetermined value is applied. Furthermore, the plate-shaped portion 21 of the attachment portion 2 can be easily sewn. In particular, high-density polyethylene (HDPE) has a good balance of flexibility, hardness, and tensile strength, so if the tassel fastener 1 is made into a resin molded product from a resin material containing high-density polyethylene (HDPE) as its main component, it is easy to obtain a tassel fastener 1 having the above-mentioned properties. In this specification, the term "main component" refers to a component that accounts for 50% or more by mass of the resin material.

[0043] The tassel fastener 1 may be colorless or may be colored with a coloring agent to match the color and pattern of the curtain tassel body 10A, for example. In addition, the tassel fastener 1 may contain additives that are commonly added to resin molded products, such as antioxidants, light stabilizers, flame retardants, heat stabilizers, and antistatic agents.

[0044] The manufacturing method of the tassel fastener 1 is not particularly limited, and it can be manufactured by, for example, resin molding, machining, etc. Examples of resin molding methods include press molding, injection molding, compression molding, and transfer molding. When manufacturing by machining, it is possible to use a method such as cutting and polishing a resin block or resin plate. In addition, it can also be manufactured using a three-dimensional modeling machine (3D printer).

[0045] According to the configuration of the tassel fastener 1 of this embodiment, it can be attached to the end of the curtain tassel body 10A and used as an end member of the curtain tassel 10, and can fasten a fastened member provided at the other end of the curtain tassel. Therefore, both ends of the curtain tassel can be connected, and curtains can be easily bundled without a tassel hook. Furthermore, the fastened member can be held in the holding space 4 defined by the hook portion 3 and the release prevention portion 5, so the held fastened member is unlikely to come off easily.

[0046] [Curtain tassels] As shown in FIG. 1 , the curtain tassel 10 has the above-described tassel fasteners 1 attached to both ends of a strip-shaped curtain tassel body 10A. The curtain tassel body 10A may be made of the same material and fabric with the same pattern as the curtain 50, or it may be made of a fabric made of a different material than the curtain 50. The tassel fastener 1 is attached by sewing the plate-like portion 21 of the attachment portion 2 to the end of the curtain tassel body 10A with a sewing machine or the like. In this embodiment, the curtain tassel body 10A is formed from fabric sewn into an elongated bag shape, and the plate-like portion 21 of the tassel fastener 1 is sewn inside the bag. In other words, the plate-like portion 21 of the tassel fastener 1 is located inside the curtain tassel body 10A and is configured so as not to be visible from the outside.

[0047] The curtain tassels 10 according to this embodiment allow the ends of the curtain tassels 10 to be fastened together from either side, making it easy to bundle the curtain 50. Furthermore, the tassel fastener 1 according to this embodiment has two hook-shaped portions 31 and two slippage prevention portions 5, thereby providing two retention spaces 4 per tassel fastener 1. Therefore, the hook-shaped portion 31 of one tassel fastener 1 of the curtain tassel 10 can be fastened to either of the two retention spaces 4 of the other tassel fastener 1 in a combination that facilitates hooking and fastening. Furthermore, the plate-shaped portions 21 of the mounting portion 2 of the tassel fastener 1 described above are attached to both ends of the curtain tassel body 10A by sewing, making the attachment process easy and providing excellent strength for the attachment portion.

[0048] [How to use curtain tassels] Next, the method of using the curtain tassel 10 equipped with the tassel fastener 1 according to this embodiment will be described separately for normal use and emergency use in which the safety function is activated.

[0049] (Normal use) When the tassel fastener 1 according to this embodiment is used to bundle curtains 50, it forms a ring-shaped structure as shown in FIG. 5 . At this time, the hook-shaped portions 31 of the tassel fastener 1 on both ends of the curtain tassel 10 are hooked together. In this way, when the curtains 50 are bundled, the strong hook-shaped portions 31 are hooked together, so the ring-shaped structure formed by the curtain tassels 10 does not easily come undone. On the other hand, when it is desired to release the ring-shaped structure formed by the curtain tassels 10, the two tassel fasteners 1 can be easily attached and detached from each other by positioning the two tassel fasteners 1 so that the openings 41 of the holding spaces 4 overlap each other at an angle of approximately 90 degrees or less, or so that the openings 41 of the holding spaces 4 and the release prevention portion 5 overlap. In this way, in the tassel fastener 1 according to this embodiment, by changing the relative positions of the two, the slip-off prevention portion 5 can be more easily removed from the opening 41 of the holding space 4, making it easier to open the ring-shaped structure.

[0050] (Emergency use) When an object or the like gets caught on the loop-shaped curtain tassel 10 as shown in FIG. 5 and an overload is applied, the hook-shaped portions 31 of the tassel fasteners 1 at both ends of the curtain tassel 10 are engaged, and the curtain tassel 10 is pulled strongly in its longitudinal direction. At this time, a tensile load of a predetermined value or more acts on the hook-shaped portions 31 of the hook portions 3, causing the hook-shaped portions 31 of the hook portions 3 to deform and open outward. The hook-shaped portions 31 where the recessed portions 33 of the hook portions 3 are located are particularly susceptible to deformation due to their small width. Deformation of this portion easily disengages the hook-shaped portion 31 of the other tassel fastener 1 from the retaining space 4. Because the tassel fastener 1 according to this embodiment is a resin molded product, the hook-shaped portions 31 deform and open, releasing the engagement, providing a safety function. For example, if the hook-shaped portion 31 of the hook section 3 is designed to deform when a tensile load of 5 kgf or more is applied in the opening direction (upward in the Y-axis direction in Figures 2 and 3), it will be easy to achieve both a normal prevention function and disengagement in the event of an overload. Note that, although the example described here is one in which the hook-shaped portions 31 of the tassel fastener 1 at both ends of the curtain tassel 10 are engaged with each other and the curtain tassel 10 is pulled strongly in its longitudinal direction, the same effect will be achieved even if the hook-shaped portion 31 of the tassel fastener 1 at one end of the curtain tassel 10 is caught on another fastened member, as the hook-shaped portion 31 will deform and open.

[0051] [Curtain set] The curtain set 100 according to this embodiment includes the above-described curtain tassel 10 and a curtain 50. The curtain 50 is installed by being hung from a curtain rail fixed to the ceiling surface of a room or a curtain rail supported on the ceiling surface of a room (the ceiling surface and curtain rail are not shown). In this installed state, the curtain 50 includes a looped string 51 (an example of a fastening member) at one end in the width direction, at a predetermined height position where the curtain tassel 10 is attached. More specifically, the looped string 51 is provided by sewing the end into at least one side hem 50A when side hems 50A are formed at both end portions of the curtain 50.

[0052] According to this configuration, when the curtain 50 is in use, as shown in Fig. 4, the looped string 51 provided on the curtain 50 can be held in the holding space 4 at one end of the curtain tassel 10. Therefore, the curtain tassel 10 can be held on the curtain 50 even if a tassel holder is not installed in the room, and the curtain tassel 10 can be put in a standby state, making it easy to quickly bundle the curtain 50 when needed. To bundle the curtain 50, for example, as shown in Fig. 5, with the curtain looped string 51 held in one of the two holding spaces 4 of the tassel fastener 1 on one end of the curtain tassel 10, the other end of the curtain tassel 10 may be wrapped around the curtain 50, and the hooked portion 31 of the tassel fastener 1 on the other end may be held in the other of the two holding spaces 4 of the tassel fastener 1 on the one end. This configuration prevents the curtain tassels 10 from shifting position when the curtains 50 are bundled, making it easy to position the curtain tassels 10 at a predetermined height on the curtains 50. In this way, the curtain set 100 according to this embodiment makes it easy to bundle the curtains 50 even in places where there is no fastening device (such as a tassel hook) for the curtain tassels 10 on a wall or the like. Note that while FIG. 5 illustrates an example in which the tassel fastening device 1 on one end of the curtain tassel 10 is hooked onto the tassel fastening device 1 on the other end of the curtain tassel 10, the hook-shaped portion 31 of the tassel fastening device 1 on the other end may also hook onto and hold the loop-shaped string 51 of the curtain 50. This configuration also makes it easy to form a ring-shaped structure for the curtain tassels 10.

[0053] [Other embodiments] Other embodiments of the tassel fastener, curtain tassel, and curtain set according to the present invention will be described below. Note that the configurations disclosed in the following embodiments can be applied in combination with the configurations disclosed in other embodiments, as long as no contradiction occurs.

[0054] In the above embodiment, an example has been described in which the tassel fastener 1 further includes a slip-off prevention portion 5 that projects from the attachment portion 2 toward the hook-shaped portion 31, and the hook portion 3 and the slip-off prevention portion 5 define the holding space 4 capable of holding the fastened member. However, the tassel fastener of the present invention is not limited to a configuration that includes the slip-off prevention portion 5, and does not necessarily need to include the slip-off prevention portion 5. For example, the tip 31A of the hook-shaped portion 31 of the hook portion 3 may be extended so as to be close to the attachment portion 2, and the holding space 4 may be defined by the hook portion 3 alone.

[0055] In the above embodiment, the configuration in which the attachment portion 2, hook portion 3, and detachment prevention portion 5 are all planar has been described as an example. However, the tassel fastener of the present invention is not limited to a configuration in which the attachment portion 2, hook portion 3, and detachment prevention portion 5 are all planar. For example, at least one of the attachment portion 2, hook portion 3, and detachment prevention portion 5 may be planar, or none of them may be planar.

[0056] In the above embodiment, the tassel fastener 1 has been described as having a configuration in which the hook portion 3 has an axial portion 32 that projects linearly from the attachment portion 2, and two hook-shaped portions 31 extend in opposite directions from the tip of the axial portion 32. However, in the present invention, the configuration of the hook portion 3 is not limited to a configuration having an axial portion 32 and two hook-shaped portions 31. For example, the axial portion 32 may not be provided, and the number of hook-shaped portions 31 may be one or three or more.

[0057] In the above embodiment, an example has been described in which the engaging surface of the hook-shaped portion 31 of the hook 3 for engaging the member to be engaged includes at least a partially curved surface. However, the present invention is not limited to a configuration in which the engaging surface of the hook-shaped portion 31 for engaging the member to be engaged includes a curved surface, and the engaging surface of the member to be engaged may be entirely flat. In other words, the portion of the hook 3 that defines the holding space 4 may include corners. Furthermore, the portion of the hook 3 that defines the holding space 4 may be flat or curved, with recesses, protrusions, etc.

[0058] In the above embodiment, the tassel fastener 1 having the shape shown in Figures 2 and 3 has been described as an example. However, in the present invention, the overall shape of the tassel fastener and the shapes of each part are not limited to those in the embodiment. For example, the hook portion 3 may be shaped to extend in the extension direction of the curtain tassel 10, and the attachment portion 2 may also be long so as to extend in the extension direction of the curtain tassel 10. Furthermore, the dimensions of each part are not limited to those described above, and may be changed as appropriate depending on the set tensile load, the material used, etc.

[0059] In the above embodiment, the tassel fastener 1 is described as an example of a structure in which the tassel fastener is a one-piece resin molded product. However, the tassel fastener of the present invention is not limited to a structure in which the tassel fastener is a one-piece resin molded product. For example, the tassel fastener may be formed by joining multiple resin parts, may be formed of metal, or may be a composite of resin and metal.

[0060] In the above embodiment, the mounting portion 2 has a plate-like portion 21 that is thinner than the hook portion 3, and the plate-like portion 21 can be sewn to the curtain tassel body 10A. However, the configuration of the mounting portion of the present invention and the method of attaching the mounting portion to the curtain tassel body 10A are not particularly limited, as long as they can be attached to the end of the curtain tassel body 10A. For example, the mounting portion may be attached to the end of the curtain tassel body 10A by applying an adhesive to the mounting portion and then heat-pressing the mounting portion. Alternatively, a button may be sewn to the mounting portion in advance and then attached to a buttonhole or the like provided at the end of the curtain tassel body 10A. Furthermore, the end of the curtain tassel body 10A may have a string-like member, and the mounting portion 2 may be a ring or the like to which the string can be attached.

[0061] The curtain tassel 10 according to the above embodiment has been described as having the tassel fasteners 1 attached to both ends of the curtain tassel body 10A. However, in the present invention, the tassel fastener 1 may be attached to only one end of the curtain tassel body 10A. In this case, the other end of the curtain tassel may be provided with a member to be fastened by the tassel fastener 1 attached to that end (for example, a string, a loop-shaped member such as a metal, a fastening hole, etc.).

[0062] In the above embodiment, an example was described in which the curtain 50 has a looped string 51 at one end in the width direction when installed, at a predetermined height where the curtain tassel 10 is attached. However, in the present invention, the curtain 50 to which the curtain tassel 10 and tassel fastening device 1 are applied does not necessarily have to have a fastening member such as the looped string 51. Furthermore, if the curtain 50 has a fastening member, the fastening member is not limited to the looped string 51 and may be various other fastening members. For example, it may be a metal ring or the like. Furthermore, in the above embodiment, an example was described in which the fastening member is provided at one end in the width direction of the curtain 50 when installed, but the fastening member may also be provided at both left and right ends in the width direction of the curtain.

[0063] In the above embodiment, the curtain set 100 installed in a facility such as a hospital has been described as an example. However, the curtain tassel fastener, curtain tassel, and curtain set of the present invention are not limited to being used in facilities, but may also be used in ordinary homes, etc. For example, the curtain tassel fastener, curtain tassel, and curtain set of the present invention are also useful when installing a partition curtain in a location such as a rental property where it is difficult to install a new tassel holder on the wall.

[0064] Regarding other configurations, it should be understood that the embodiments disclosed in this specification are illustrative in all respects and that the scope of the present invention is not limited thereby. Those skilled in the art will easily understand that appropriate modifications are possible without departing from the spirit of the present invention. Therefore, other embodiments modified without departing from the spirit of the present invention are naturally included in the scope of the present invention. [Industrial Applicability]
