[0027] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the rope fastener 1 of the first embodiment is installed at both ends of the rope 2, namely rope end 2A and rope end 2B, and includes: a cylindrical outer shell component 3; and a suspension component 4, which is inserted into the outer shell component 3 and suspends the rope end 2A and rope end 2B. Furthermore, the rope fastener 1 of the first embodiment and the rope 2 on which the rope fastener 1 is installed constitute a pendant 10. The way this pendant 10 is used is not particularly limited; for example, by installing the rope fastener 1 on a strap component and installing the rope 2 on any item, an item and a strap component can be connected.

[0029] The construction and materials of rope 2 are not particularly limited. For example, such as Figure 2 As illustrated in the example, the rope 2 of this embodiment includes a core 21 and a plurality of covering layers 22 stacked around and covering the core 21. It should be noted that the covering layer 22 surrounding the core 21 is not limited to multiple layers and can be a single layer.

[0030] (Structure of rope fasteners)

[0031] Reference Figures 3-9 The structure of the rope fastener 1 in this embodiment will be described. It should be noted that... Figure 4 , Figure 5 as well as Figure 9 In the diagram, rope ends 2A and 2B are indicated by dashed lines. Furthermore, Figure 6 The state of the suspension component 4 is shown when the housing component 3 is inserted. Figure 7 The state of the suspension component 4 before the housing component 3 is inserted is shown.

[0032] In the following description, the axial direction of the outer casing 3 is defined as the Z direction, the insertion direction of the suspension component 4 relative to the outer casing 3 is defined as the +Z direction, and its opposite direction is defined as the -Z direction. Furthermore, the radial direction orthogonal to the axial direction of the outer casing 3 is defined as the X direction, and the rope ends 2A and 2B are arranged in the X direction. Additionally, the direction orthogonal to both the axial direction of the outer casing 3 and the aforementioned radial direction is defined as the Y direction. It should be noted that the Y direction is the first radial direction, and the X direction is the second radial direction.

[0033] The outer casing component 3 is, for example, a resin molded product. Figures 3-5 As shown, the outer casing component 3 includes: a side wall portion 31 extending in the Z direction; an opening portion 32 opening toward the -Z side of the side wall portion 31; a bottom portion 33 disposed at the +Z side end of the side wall portion 31; and a rope extension hole 34 penetrating the bottom portion 33 in the Z direction.

[0034] The sidewall portion 31 extends to surround the space within the outer casing member 3 and has a generally cylindrical shape. The inner surface 311 of the sidewall portion 31 is configured to be generally parallel to the Z direction. The outer surface 312 of the sidewall portion 31 has: an inclined surface 313, which is slightly inclined relative to the Z direction such that the outer diameter of the cylindrical shape of the sidewall portion 31 decreases towards the Z-side end of the sidewall portion 31; and a protrusion 314, which protrudes radially outward from the inclined surface 313 near the Z-side end of the sidewall portion 31. It should be noted that a pair of recesses 315 are formed at the edge of the sidewall portion 31 surrounding the opening 32, which are configured to clamp the suspension member 4.

[0035] The bottom 33 forms a bottom surface 331 facing the Z direction relative to the internal space of the outer shell component 3. This bottom surface 331 is a flat surface that is approximately parallel to a surface orthogonal to the Z direction.

[0036] The shape and number of rope extension holes 34 are not particularly limited as long as they allow rope ends 2A and 2B to pass through. For example, Figure 8As shown, the rope extension hole 34 in this embodiment is a hole through which both rope ends 2A and 2B are inserted. The cross-sectional shape of the rope extension hole 34, which is orthogonal to the Z direction, has a shape in which the central portion in the X direction narrows in the Y direction. In other words, the cross-sectional shape of the rope extension hole 34 has a shape in which two circular portions arranged in the X direction overlap. It should be noted that the rope extension hole 34 can be two holes arranged in the X direction, so that rope ends 2A and 2B can be inserted respectively.

[0037] The suspension component 4 is, for example, a resin molded part. Figure 6 as well as Figure 7 As shown, the suspension component 4 deforms before and after being inserted into the housing component 3. Hereinafter, the suspension component 4 in the state of being inserted into the housing component 3 will be described in detail.

[0038] like Figure 6 As shown, the suspension component 4 includes: a head 41; a torso 42 extending from the head 41 in the +Z direction; and a rope insertion hole 43 penetrating the torso 42 in the Y direction.

[0039] The head 41 is disposed at one end of the housing component 3, namely the opening 32. The head 41 has a flat cylindrical shape that is integrally fitted into the opening 32 (see reference). Figure 3 and Figure 4 ).

[0040] The torso 42 is housed within the outer shell component 3 (see reference). Figure 4 and Figure 5 The torso 42 has a plate shape with an overall thickness in the Y direction. Specifically, the torso 42 includes: a torso body portion 421; and a pair of connecting portions 422 and 423, which hold a rope insertion hole 43 in the X direction and connect the head 41 to the torso body portion 421.

[0041] like Figure 5 and Figure 6 As shown, the torso body 421 includes a first rope support portion 47 and a second rope support portion 48 facing opposite sides in the Y direction. Both the first rope support portion 47 and the second rope support portion 48 are arranged such that they clamp the rope insertion hole 43 between themselves and the head 41 in the Z direction. Furthermore, the first rope support portion 47 and the second rope support portion 48 respectively form rope spaces S1 and S2 for arranging rope ends 2A and 2B between themselves and the inner surface 311 of the side wall portion 31.

[0042] The first rope support portion 47 has: a support surface 471 that widens toward the +Z side of the rope insertion hole 43 and faces the -Y direction; and a plurality of protrusions 472 that protrude from the support surface 471 toward the -Y direction. The plurality of protrusions 472 are arranged in the Z direction, and each protrusion 472 has a shape that extends along the X direction.

[0043] Similarly, the second rope support 48 has: a support surface 481 that widens toward the +Z side of the rope insertion hole 43 and faces the +Y direction; and a plurality of protrusions 482 that protrude from the support surface 481 toward the +Y direction. The plurality of protrusions 482 are arranged in the Z direction, and each protrusion 482 has a shape that extends along the X direction.

[0044] It should be noted that the dimension H1 of the first rope support part 47 and the second rope support part 48 in the Z direction is preferably more than half of the dimension H2 of the torso 42 in the Z direction (refer to...). Figure 6 ).

[0045] In the torso 42 adjacent to the head 41, a rope insertion hole 43 penetrates the torso 42 in the Y direction. The cross-sectional shape of the rope insertion hole 43 only needs to be such that the rope ends 2A and 2B arranged in the X direction can be inserted through it, for example, a rectangle (see reference). Figure 4 ).

[0046] In addition, such as Figure 6 As shown, the suspension member 4 of this embodiment includes: a pair of segmented pieces 401 and 402, which together constitute the head 41 and the torso 42 described above, and a slit 44 is formed between them; a base 45, which connects the pair of segmented pieces 401 and 402; and a through hole 46, which penetrates the torso 42 at a position adjacent to the base 45.

[0047] The slit 44 extends along the Z direction from the central portion of the suspension member 4 in the X direction and penetrates the suspension member 4 in the Y direction. The slit 44 includes a slit portion 441 passing through the head 41 and a slit portion 442 passing through the torso 42. The head 41 is divided into a pair of head blocks 41A and head blocks 41B by the slit portion 441, and the torso 42 is divided into a pair of torso blocks 42A and torso blocks 42B by the slit portion 442.

[0048] In other words, segment 401 includes the head 41 on the -X side, i.e., head block 41A, and the torso 42 on the -X side, i.e., torso block 42A, and segment 402 includes the head 41 on the +X side, i.e., head block 41B, and the torso 42 on the +X side, i.e., torso block 42B. It should be noted that the first rope support portion 47 and the second rope support portion 48 are respectively located in torso block 42A and torso block 42B.

[0049] Head block 41A and head block 41B have a dividing surface 411 that contacts each other in the X direction. Body block 42A and body block 42B have: a hole edge 431 that is provided opposite to each other in the X direction through a rope insertion hole 43; and a hole edge 432 that faces the -Z direction relative to the rope insertion hole 43.

[0050] It should be noted that the width of the slit 44 in the X direction varies depending on its position in the Z direction. Specifically, slit portion 441 does not form a gap between head block portion 41A and head block portion 41B (i.e., a pair of dividing surfaces 411 and 412 are in contact with each other), while slit portion 442 forms a gap between torso block portion 42A and torso block portion 42B. Here, the size of the gap between torso block portion 42A and torso block portion 42B in the X direction is closer to the +Z side than the central portion of the torso 42 in the Z direction, and it becomes larger towards the +Z direction.

[0051] The base 45 is connected to the +Z side end of the torso 42 (i.e., the +Z side end of torso block 42A and torso block 42B), and connects a pair of segmented pieces 401 and 402. Furthermore, as... Figure 5 As shown, the base 45 has a plate shape that is wider than the torso 42 in the Y direction. That is, similar to the protrusions 472 and 482, the base 45 protrudes further towards the +Y side and further towards the -Y side than the torso 42, respectively. Furthermore, the base 45 has a facing surface 451 around the rope extension hole 34, opposite to the bottom surface 331. This facing surface 451 is not particularly limited, but it is preferably flat.

[0052] like Figure 6 As shown, the through hole 46 penetrates the body section 42 at a position adjacent to the base 45. Therefore, a portion of the body section 42 located on both sides of the through hole 46 in the X direction functions as hinge portion 424 and hinge portion 425. Figure 6 and Figure 7 As shown, the hinge portion 424 and hinge portion 425 are capable of elastic deformation in the X direction.

[0053] It should be noted that hinge portion 424 and hinge portion 425 undergo elastic deformation, thereby allowing the suspension component 4 of this embodiment to... Figure 7 The state shown is transformed into Figure 6 The state shown. When suspension component 4 is Figure 7 In the state shown, a gap is formed between the dividing piece 401 and the dividing piece 402 to the extent that the rope end 2A and the rope end 2B can be inserted.

[0054] (Installation method for rope fasteners)

[0055] The following describes the installation method of installing the rope fastener 1 of this embodiment onto the rope 2.

[0056] First, pass the rope 2 through the outer casing component 3. Specifically, the loop portion of the folded rope 2 can be passed through the rope extension hole 34 from the opening 32 of the outer casing component 3, or the rope ends 2A and 2B can be passed through the opening 32 from the rope extension hole 34 of the outer casing component 3.

[0057] Next, prepare Figure 7 The suspension component 4 is shown. Then, by passing rope ends 2A and 2B through the gap between the dividing plates 401 and 402, rope ends 2A and 2B are suspended from the edges 432 of the holes in the dividing plates 401 and 402. At this time, rope ends 2A and 2B are arranged in the X direction. Furthermore, rope ends 2A and 2B are suspended from the entire torso 42 in a manner that clamps the torso 42 in the Y direction.

[0058] Finally, the suspension member 4, together with the rope ends 2A and 2B, is inserted into the outer casing member 3 through the opening 32, and the head 41 is fitted into the opening 32. At this time, the base 45 of the suspension member 4 is guided by a pair of recesses 315 of the outer casing member 3. Furthermore, as the suspension member 4 is inserted into the outer casing member 3, the dividing plates 401 and 402 are pushed against each other and approach each other in the X direction due to the sidewall portions 31, thereby causing the hinge portions 424 and 425 to undergo elastic deformation. As a result, the respective dividing surfaces 411 and 412 of the dividing plates 401 and 402 come into contact with each other, and the edge portions 431 of the holes of the dividing plates 401 and 402 clamp the rope ends 2A and 2B in the rope insertion hole 43 in the X direction (see reference). Figure 4 ).

[0059] Furthermore, if the suspension member 4 is inserted into the outer casing member 3, a rope space S1 is formed between the first rope support portion 47 and the inner surface 311 of the side wall portion 31, and a rope space S2 is formed between the second rope support portion 48 and the inner surface 311 of the side wall portion 31. These rope spaces S1 and S2 are respectively provided with rope ends 2A and 2B (see reference). Figure 5 and Figure 9 Specifically, rope end 2A contacts the first rope support portion 47 and the second rope support portion 48 in the torso block portion 42A, and is held by the first rope support portion 47 and the side wall portion 31, and is also held by the second rope support portion 48 and the side wall portion 31. Similarly, rope end 2B contacts the first rope support portion 47 and the second rope support portion 48 in the torso block portion 42B, and is held by the first rope support portion 47 and the side wall portion 31, and is also held by the second rope support portion 48 and the side wall portion 31.

[0060] As described above, the rope fastener 1 is installed at both ends of the rope 2A and 2B. Thus, a pendant 10 having the rope 2 and the rope fastener 1 can be manufactured.

[0061] (Effects of this implementation method)

[0062] (1) As described above, the rope fastener 1 of this embodiment includes: a housing member 3 having a side wall portion 31 extending in the axial direction (Z direction) and an opening portion 32 opening in the -Z direction; and a suspension member 4 for suspending rope ends 2A and 2B and for inserting into the housing member 3 from the opening portion 32. The suspension member 4 includes: a head 41 that protrudes out of the housing member 3 from the opening portion 32; a torso 42 that extends axially from the head 41 within the housing member 3; and a rope insertion hole 43 that penetrates the torso 42 in a first radial direction (Y direction) orthogonal to the axial direction. The torso 42 is disposed on the opposite side of the head 41 relative to the rope insertion hole 43. Furthermore, it includes a first rope support portion 47 and a second rope support portion 48 facing opposite sides in the first radial direction. The first rope support portion 47 and the second rope support portion 48 form rope spaces S1 and S2 respectively between themselves and the side wall portion 31 for suspending rope ends 2A and 2B.

[0063] According to this structure, the rope ends 2A and 2B, pulled into the outer casing 3, are suspended from the entire body 42 of the suspension component 4 through the rope insertion hole 43. Thus, the rope ends 2A and 2B are both disposed in the rope space S1 between the first rope support portion 47 and the side wall portion 31, and in the rope space S2 between the second rope support portion 48 and the side wall portion 31. That is, the rope ends 2A and 2B are clamped by the rope fastener 1 in each of the two rope spaces S1 and S2 within the rope fastener 1, causing friction between them. Therefore, the rope fastener 1 of this embodiment can be reliably installed on the rope ends 2A and 2B, ensuring the fixing strength of the rope fastener 1 relative to the rope ends 2A and 2B even when using a stiffer rope 2.

[0064] (2) In this embodiment, the outer shell component 3 further includes: a bottom 33, which is disposed opposite to the opening 32; and a rope extension hole 34, which extends through the bottom 33 in the axial direction, and the suspension component 4 has a facing surface 451 disposed around the rope extension hole 34 opposite to the bottom surface 331.

[0065] With this structure, when the rope 2 extending from the rope extension hole 34 to the outside of the outer casing 3 is stretched, a force in the stretching direction is applied to the suspension member 4, thereby pushing the opposing surface 451 to the bottom 33. At this time, since the opposing surface 451 of the suspension member 4 is in large-area contact with the bottom 33 around the rope extension hole 34, the stress concentration applied to the suspension member 4 can be suppressed. Thus, damage to the suspension member 4 can be prevented.

[0066] Furthermore, by clamping the rope end 2A and rope end 2B between the opposite surface 451 of the suspension member 4 and the bottom 33, the fixing strength of the rope fastener 1 relative to the rope 2 can also be improved.

[0067] (3) In this embodiment, the cross-sectional shape of the rope protrusion hole 34 orthogonal to the Z direction has a shape in which the central part in the X direction narrows in the Y direction.

[0068] With this structure, as a method of inserting the two rope ends 2A and 2B through the rope extension hole 34, the loop portion of the folded rope 2 can pass through the rope extension hole 34 from the opening 32 of the outer casing 3. Furthermore, the arrangement of the two rope ends 2A and 2B within the rope extension hole 34 can be stabilized.

[0069] (4) In this embodiment, the first rope support portion 47 and the second rope support portion 48 respectively have a support surface 471 and a support surface 481 provided opposite to the side wall portion 31, and a plurality of protrusions 472 and protrusions 482 protruding from the support surface 471 and the support surface 481.

[0070] With this structure, the friction between the protrusions 472 and 482 and the rope 2 can be increased, thereby improving the fixing strength of the rope fastener 1 relative to the rope 2.

[0071] It should be noted that, in this embodiment, since the base 45 has the same protruding shape as the protrusions 472 and 482, the fixing strength of the rope fastener 1 relative to the rope 2 can be further improved.

[0072] (5) In this embodiment, the suspension component 4 further includes: a pair of dividing pieces 401 and 402, which together constitute the head 41 and the torso 42, and a slit 44 is formed between them; and a base 45, which connects the pair of dividing pieces 401 and 402, the slit 44 dividing the head 41 and the torso 42, and communicating with the rope insertion hole 43.

[0073] With this structure, before the suspension member 4 is inserted into the housing member 3, the pair of split pieces 401 and 402 can move closer or further apart with the base 45 as a fulcrum. When the pair of split pieces 401 and 402 are far apart, it is easy to arrange the rope ends 2A and 2B in the rope insertion hole 43. As a result, the installation of the rope fastener 1 relative to the rope 2 can be easily performed.

[0074] (6) In this embodiment, the suspension component 4 also has a through hole 46, which passes through the body 42 in the first radial direction (Y direction) at a position adjacent to the base 45 and communicates with the slit 44 in the axial direction.

[0075] With this structure, the portion of the body 42 near the through hole 46 is easily elastically deformed, thus functioning as hinge parts 424 and 425 when the pair of segmented pieces 401 and 402 approach or move away from each other. This allows for easy installation of the rope fastener 1 relative to the rope 2.

[0076] (7) In this embodiment, a pair of dividing pieces 401 and 402 have a pair of dividing surfaces 411 and 412, wherein when the suspension member 4 is inserted into the housing member 3, the pair of dividing surfaces 411 and 412 are in contact with each other at the head 41.

[0077] With this structure, the loosening of the dividing pieces 401 and 402 within the housing component 3 can be suppressed, thereby improving the fixing strength of the rope fastener 1 relative to the rope 2.

[0078] It should be noted that, in this embodiment, when the suspension member 4 is inserted into the outer casing member 3, the slit 44 does not form a gap between the head block portion 41A and the head block portion 41B, but a gap is formed between the torso block portion 42A and the torso block portion 42B. Based on the shape of this slit 44, when the dividing pieces 401 and 402 approach each other, interference between the rope 2 or the torso block portion 42A and the torso block portion 42B can be suppressed, ensuring that the pair of dividing surfaces 411 and 412 are in solid contact.

[0079] (8) In this embodiment, a pair of dividing pieces 401 and 402 have a pair of hole edges 431 that are provided opposite to each other in a second radial direction (X direction) that is orthogonal to the axial direction and the first radial direction, respectively.

[0080] With this structure, a pair of hole edges 431 can clamp the rope ends 2A and 2B inside the rope insertion hole 43 in the X direction. As a result, the fixing strength of the rope fastener 1 relative to the rope 2 can be improved.

[0081] (9) In this embodiment, the first rope support portion 47 and the second rope support portion 48 each have an axial (Z direction) dimension H1 that is more than half of the axial dimension H2 of the torso 42.

[0082] With this structure, the area of ​​friction between the rope fastener 1 and the rope 2 can be ensured, thus improving the fixing strength of the rope fastener 1 relative to the rope 2.

[0083] (10) The pendant 10 of this embodiment includes the rope fastener 1 described above and a rope 2 for mounting the rope fastener 1. Here, the rope 2 includes: a core 21; and one or more covering layers 22 surrounding and covering the core 21. With this structure, the tensile strength of the pendant 10 is improved because the fixing strength of the rope fastener 1 relative to the rope 2 is increased. That is, the pendant 10 of this embodiment can securely mount the rope fastener 1 to the rope 2, and at the same time improve the hanging strength of the item.

[0084] (11) Furthermore, in this embodiment, the first rope support portion 47 and the second rope support portion 48 are respectively disposed along the inner surface 311 of the sidewall portion 31. Therefore, it is possible to ensure a certain range of frictional force between the rope fastener 1 and the rope 2 over a wider range. In addition, in this embodiment, the outer surface 312 of the sidewall portion 31 has a shape that is easy for the operator to grip with their fingers.

[0085] (Modified Example)

[0086] In the above embodiments, the specific shapes of the outer casing component 3 and the suspension component 4 can be arbitrarily changed. Hereinafter, in the description of variations, the same reference numerals will be used for structures corresponding to the above embodiments.

[0087] (First variation)

[0088] like Figure 10 As shown, in the suspension component 4A of the modified example, the first rope support portion 47 can be configured to have a protrusion 472. Furthermore, although not shown in the figure, the second rope support portion 48, like the first rope support portion 47, can also be configured to have a protrusion 482. Even in this modified example, the rope fastener 1 can be installed on the rope end 2A and the rope end 2B in the same manner as in the above embodiment. It should be noted that the protrusions 472 and 482 are preferably formed adjacent to the rope insertion hole 43.

[0089] (Second variation)

[0090] like Figure 11As shown, in the suspension member 4B of the modified example, the base 45 may include: a plate portion 455 that connects a pair of segmented pieces 401 and 402; and a plurality of protrusions 456 that protrude from the segmented pieces 401 and 402 in the +Z direction. Similar to the base 45 of the above embodiment, the plate portion 455 protrudes from the torso 42 in the +Y direction and from the torso 42 in the -Y direction, respectively. The plurality of protrusions 456 protrude towards the bottom 33 and are arranged centered on the rope extension hole 34.

[0091] In this modified example, unlike the embodiment described above, a gap in the Z direction is ensured between the rope extension hole 34 and the plate portion 455 of the base 45 for the rope ends 2A and 2B to pass through, and multiple protrusions 456 contact the bottom 33. Since these multiple protrusions 456 are arranged centered on the rope extension hole 34, the stress applied to the suspension member 4B when the rope 2 is stretched is evenly distributed to the multiple protrusions 456, thereby preventing concentration in one place.

[0092] (Third variation)

[0093] like Figure 12 As shown, the suspension member 4C in the modified example may not have the slit 44 of the above embodiment. That is, the head 41 and body 42 of the suspension member 4C may not have the segmented shape shown in the above embodiment. In this modified example, when the rope fastener 1 is installed on the rope 2, it is only necessary to perform the operation of inserting the rope end 2A and the rope end 2B through the rope insertion hole 43 in the Y direction.

[0094] In addition, such as Figure 12 As shown, in the suspension component 4C involved in the modified example, the base 45 may have a plurality of protrusions 456 arranged in the same manner as in the second modified example described above.

[0095] (Other variations)

[0096] The method of suspending rope ends 2A and 2B relative to suspension member 4 is not limited to the method described in the above embodiments. For example, rope ends 2A and 2B can be suspended more than once around the entire torso 42 by passing rope ends 2A and 2B through the +Z side of base 45, or rope ends 2A and 2B can be crossed over each other within the outer casing member 3.

[0097] In the above embodiments, the case where the rope fastener 1 is installed at both ends of the rope 2, namely rope end 2A and rope end 2B, has been described; however, the present invention is not limited thereto. For example, the rope fastener 1 may be installed at one end of the rope 2.

[0098] In the above embodiment, the outer casing component 3 has a cylindrical shape, but it may also have other cylindrical shapes such as polygonal prisms. Furthermore, the shape of the suspension component 4 can be deformed to match the shape of the outer casing component 3.

[0099] In the above embodiment, the arrangement of the rope insertion hole 43 in the suspension component 4 is not limited to the position adjacent to the head 41, but can also be any position in the torso 42.

[0100] In the above embodiment, the first rope support portion 47 and the second rope support portion 48 may not have protrusions 472 and 482 respectively. With such a structure, the rope end 2A and the rope end 2B can be clamped between the support surfaces 471 and 481 of the first rope support portion 47 and the second rope support portion 48 and the side wall portion 31.

[0101] In the above embodiment, the plate-shaped base 45 forms a planar opposing surface 451, but the present invention is not limited to this. For example, the base 45 may not be plate-shaped, but may have other shapes (e.g., a stepped shape). In addition, the base 45 may have opposing surfaces 451 with concave and convex features.

[0102] In the second and third modifications described above, two protrusions 456 in the suspension member 4 are illustrated; however, the number and shape of the plurality of protrusions 456 in the suspension member 4 are not limited in each modification. That is, the suspension member 4 may be provided with three or more protrusions 456 arranged centered on the rope extension hole 34. Furthermore, each protrusion 456 may have a face that contacts the bottom 33.
