Description

[Technical Field]

[0001] The present invention relates to a fastener for a clothing accessory used to open and close both ends of a string-like body of a string-like clothing accessory, and to a clothing accessory equipped with the fastener. [Background technology]

[0002] There are many known fasteners for accessories that open and close (attach and detach) both ends of a string-like body (such as a strap, chain, or metal wire) of a string-like accessory such as a neck strap, necklace, bracelet, etc. Most of these fasteners have a male or female member at the end of the string-like body, and the two members are detachably engaged with each other (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3094783 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the fastener for jewelry described in Patent Document 1, the protrusion on the male component is pressed into the engagement retaining portion of the female component, which is made of an elastic material, to engage it, so there is a concern that the engagement retaining portion of the female component may deteriorate due to repeated attachment and detachment of the male component and female component.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a fastener for jewelry that can suppress deterioration of the male and female components while ensuring ease of connection between the male and female components, and an ornament equipped with the same. [Means for solving the problem]

[0006] The present invention provides a means for solving the above-mentioned problems as follows: That is, the fastener for jewelry of the present invention comprises a male member and a female member and is used to open and close both ends of a string-like body, wherein the male member is configured by integrally joining a body portion having a through hole extending along the longitudinal direction and a protrusion having an engagement portion, the female member comprises a second body portion having a second through hole extending along the longitudinal direction, the engagement portion comprises a ball, a recess for accommodating the ball, and a spring for urging the ball outward from the recess, the protrusion of the male member is inserted into the second through hole of the female member to connect the male and female members, and in this connected state, the ball engages with the inner wall surface of a groove formed in the inner wall surface of the second through hole of the female member due to the urging force of the spring.

[0007] The above configuration ensures ease of connection between the male and female components and prevents deterioration of the male and female components. Specifically, when connecting the male and female components, the protrusion of the male component is pushed into the second through-hole of the female component, causing the ball of the engagement portion on the protrusion to engage with the groove of the second through-hole of the female component. When the fastener is in a connected state, the ball, biased by the spring of the engagement portion, engages with the inner wall surface of the groove of the through-hole of the female component, preventing the male and female components from being easily released from connection. This allows the male and female components to be easily connected and the connected state of the male and female components to be easily maintained.

[0008] On the other hand, when disconnecting the male and female components, the protrusion of the male component is pulled out of the second through-hole of the female component. At this time, the ball of the engagement portion comes into contact with the periphery of the inner wall surface of the groove, exerting a force on the ball toward the interior of the recess. This causes the ball to retreat toward the interior of the recess against the biasing force of the spring, disengaging the ball from the inner wall surface of the groove of the through-hole of the female component, and separating the male and female components. Repeated attachment and detachment of the male and female components may gradually wear away the periphery of the inner wall surface of the groove of the through-hole of the female component. However, because the ball is spherical, it hardly wears at all. Therefore, even if the periphery of the inner wall surface of the groove of the second through-hole of the female component wears slightly, the ball can reliably engage with the inner wall surface of the groove, and deterioration of the male and female components can be suppressed compared to when an elastic material such as rubber is used.

[0009] In the above configuration, it is preferable that the through hole of the male component is provided with a step portion so that one end of the string-like body inserted into the through hole can be caught on the step portion, and the second through hole of the female component is provided with a second step portion so that the other end of the string-like body inserted into the second through hole can be caught on the second step portion. This prevents the end of the string-like body from being detached from the male component and the female component by catching on the step portion. This makes it easy to attach the male component and the female component to the string-like body.

[0010] In the above configuration, it is preferable that the body portion of the male component and the second body portion of the female component have the same shape, which allows the body portion of the male component and the second body portion of the female component to be made from the same part, reducing the number of manufacturing steps for the fastener for ornaments and improving productivity of the fastener for ornaments.

[0011] Furthermore, the ornament of the present invention is characterized by including the fastener for an ornament having the above-described configuration, and has the same effects as those of the fastener for an ornament having the above-described configuration. [Effects of the Invention]

[0012] According to the present invention, it is possible to ensure ease of connection between the male member and the female member, and to suppress deterioration of the male member and the female member. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] The fastener for accessories (also simply referred to as "fastener") 10 shown in Figs. 1 to 6 is used for string-like accessories such as neck straps, and is used to open and close (attach and detach) both ends of a string-like body 11 such as a strap. Figs. 1 and 2 are front views of fastener 10, and Figs. 3 and 4 are cross-sectional views showing the internal structure of fastener 10. Figs. 1 and 3 show fastener 10 in a connected state, and Figs. 2 and 4 show fastener 10 in a separated state. Fig. 5 is a cross-sectional view showing the body 21 and protrusion 22 of male member 20 of fastener 10 in an exploded state, and Fig. 6 is a cross-sectional view showing engagement portion 40 provided on male member 20 of fastener 10.

[0016] As shown in Figures 1 to 6, fastener 10 is composed of a male member 20 and a female member 30, both of which can be opened and closed (detached). One end of string-like body 11 is connected to male member 20, and the other end of string-like body 11 is connected to female member 30. In the separated state of fastener 10 shown in Figures 2 and 4, male member 20 and female member 30 are separated, so that both ends of string-like body 11 are open. In the connected state of fastener 10 shown in Figures 1 and 3, male member 20 and female member 30 are joined, so that both ends of string-like body 11 are closed, and string-like body 11 is formed into a ring shape. For example, a metal wire coated with a synthetic resin film is used as string-like body 11.

[0017] The male member 20 has a substantially cylindrical body 21 and a substantially columnar protrusion 22, and the body 21 and the protrusion 22 are integrally joined together. The body 21 and the protrusion 22 are made of metal, for example, stainless steel.

[0018] The diameter of the body 21 is larger at the tip 21a (left end in the figure) side in the longitudinal direction than at the end 21b (right end in the figure) side, and the outer shape of the body 21 is formed in a truncated cone shape. A through-hole 21c is formed in the body 21, penetrating from the tip 21a to the end 21b. The through-hole 21c extends along the longitudinal direction. The body 21 has a shape that is rotationally symmetrical with respect to a central axis that is along the longitudinal direction.

[0019] As shown in FIG. 5, the portion on the tip 21a side of the through-hole 21c is a large-diameter portion 21d, and the portion on the end 21b side of the through-hole 21c is a small-diameter portion 21f. The portion between the large-diameter portion 21d and the small-diameter portion 21f of the through-hole 21c is a middle-diameter portion 21e. The inner diameter D11 of the large-diameter portion 21d is larger than the inner diameter D12 of the middle-diameter portion 21e, and the inner diameter D12 of the middle-diameter portion 21e is larger than the inner diameter D13 of the small-diameter portion 21f (D13 < D12 < D11). An inclined portion (step portion) 21g is provided between the large-diameter portion 21d and the middle-diameter portion 21e. An inclined portion (step portion) 21h is provided between the middle-diameter portion 21e and the small-diameter portion 21f. In the inclined portions 21g and 21h, the inner diameter gradually decreases from the tip 21a side toward the end 21b side. Further, an annular groove portion 21i that is recessed toward the outer diameter side is formed on the inner wall surface of the intermediate portion in the longitudinal direction of the large-diameter portion 21d. The body portion 21 having the through-hole 21c as described above can be formed, for example, by cutting.

[0020] As shown in FIG. 5, the protrusion 22 is formed to have substantially the same diameter from the tip 22a (left end in the figure) side to the end 22b (right end in the figure) side in the longitudinal direction, and the outer diameter D21 of the portion on the tip 22a side and the outer diameter D22 of the portion on the end 22b side are substantially the same. On the other hand, the outer diameter D23 of the large-diameter portion 22c on the tip 22a side of the protrusion 22 is slightly larger than the outer diameter D21 of the portion on the tip 22a side and the outer diameter D22 of the portion on the end 22b side (D21 ≒ D22 < D23). The protrusion 22 having the large-diameter portion 22c as described above can be formed, for example, by cutting.

[0021] The outer diameter D22 of the portion on the end 22b side of the protrusion 22 is substantially the same as the inner diameter D11 of the large-diameter portion 21d of the through-hole 21c of the body portion 21 (D11≈D22). By inserting the portion on the end 22b side of the protrusion 22 into the inside of the large-diameter portion 21d on the tip 21a side of the through-hole 21c of the body portion 21, the body portion 21 and the protrusion 22 are integrally joined. Here, in the disassembled state of the body portion 21 and the protrusion 22, since the outer diameter D23 of the large-diameter portion 22c of the protrusion 22 is slightly larger than the inner diameter D11 of the large-diameter portion 21d of the through-hole 21c of the body portion 21 (D11<D23), for example, by inserting the protrusion 22 to a predetermined position of the large-diameter portion 21d of the through-hole 21c by press-fitting, the body portion 21 and the protrusion 22 can be firmly joined.

[0022] As shown in FIG. 4, in the state where the body portion 21 and the protrusion 22 are joined, the tip portion 22d on the tip 22a side of the protrusion 22 protrudes from the tip 21a side of the through-hole 21c of the body portion 21. In this case, approximately half of the portion on the end 22b side of the protrusion 22 is inserted into the inside of the through-hole 21c of the body portion 21, and approximately half of the portion on the tip 22a side of the protrusion 22 protrudes from the through-hole 21c of the body portion 21. An engaging portion 40 for engaging with the female member 30 is provided on the tip portion 22d of the protrusion 22.

[0023] As shown in FIGS. 5 and 6, the engaging portion 40 includes, for example, a stainless steel ball (locking member) 41, a recess 42 for accommodating the ball 41, a spring 43 for biasing the ball 41 toward the outer side in the radial direction (outside of the recess 42), and a stopper 44 for preventing the ball 41 from falling off. Specifically, a substantially cylindrical recess 42 is formed in the tip portion 22 of the protrusion 22. The recess 42 can be formed, for example, by cutting. The ball 41 is accommodated inside the recess 42, and a spring 43 is disposed in a compressed state between the ball 41 and the bottom 42a of the recess 42. By the spring 43, the ball 41 is biased toward the outer side in the radial direction, and the upper end portion of the ball 41 protrudes from the outer peripheral surface of the tip portion 22d of the protrusion 22. In this case, as shown in FIG. 6, a portion about 1 / 3 to 1 / 4 of the diameter of the ball 41 protrudes from the outer peripheral surface of the tip portion 22d of the protrusion 22.

[0024] A stopper 44 is formed on the upper edge of the recess 42. The stopper 44 is, for example, a protrusion that protrudes toward the inner diameter of the recess 42. In this case, multiple stoppers 44 may be provided at predetermined intervals, or a continuous annular stopper 44 may be provided. When the ball 41 abuts against the stopper 44, the ball 41 is restricted from moving radially outward, preventing it from falling out of the recess 42. Furthermore, by pressing the ball 41 from the outside, the ball 41 can be retracted to the position indicated by the two-dot chain line inside the recess 42 against the biasing force of the spring 43. An opening 42b with a diameter smaller than the inner diameter of the recess 42 is formed in the bottom 42a of the recess 42. The stopper 44 is formed by, for example, pressing the upper edge of the recess 42 after the spring 43 and ball 41 are sequentially placed in the recess 42.

[0025] The female member 30 has a substantially cylindrical body portion 31. The body portion 31 is made of a metal such as stainless steel. In this embodiment, the body portion 31 of the female member 30 has the same shape as the body portion 21 of the male member 20. The tip end 21a side of the body portion 21 of the male member 20 and the tip end 31a side of the body portion 31 of the female member 30 are arranged to face each other, and the body portion 21 of the male member 20 and the body portion 31 of the female member 30 are arranged symmetrically. For this reason, as shown in FIG. 1 , when the fastener 10 is in a connected state, the fastener 10 has a symmetrical shape.

[0026] 4, the diameter of the body 31 is larger at the tip 31a (right end in the figure) in the longitudinal direction than at the end 31b (left end in the figure), and the outer shape of the body 31 is formed in a truncated cone shape. The body 31 is formed with a through-hole 31c that penetrates from the tip 31a to the end 31b. The through-hole 31c extends along the longitudinal direction. The body 31 has a shape that is rotationally symmetrical with respect to a central axis that is along the longitudinal direction.

[0027] As shown in FIG. 4, a portion of the tip 31a side of the through-hole 31c is a large-diameter portion 31d, and a portion of the opposite 31b of the through-hole 31c is a small-diameter portion 31f. The portion between the large-diameter portion 31d and the small-diameter portion 31f of the through-hole 31c is a middle-diameter portion 31e. The inner diameter D31 of the large-diameter portion 31d is larger than the inner diameter D32 of the middle-diameter portion 31e, and the inner diameter D32 of the middle-diameter portion 31e is larger than the inner diameter D33 of the small-diameter portion 31f (D33 < D32 < D31). An inclined portion (step portion) 31g is provided between the large-diameter portion 31d and the middle-diameter portion 31e. An inclined portion (step portion) 31h is provided between the middle-diameter portion 31e and the small-diameter portion 31f. In the inclined portions 31g and 31h, the inner diameter gradually decreases from the tip 31a side toward the opposite 31b side. Further, an annular groove portion 31i recessed toward the outer diameter side is formed on the inner wall surface of the intermediate portion in the longitudinal direction of the large-diameter portion 31d. The radius of curvature of the groove portion 31i is substantially the same as the radius of the ball 41 of the engaging portion 40 provided on the protrusion 22. The body portion 31 having the through-hole 31c as described above can be formed by, for example, cutting.

[0028] Then, from the separated state of the fastener 10 shown in FIGS. 2 and 4, the male member 20 and the female member 30 are connected by inserting a portion of the tip 22a side of the protrusion 22 of the male member 20 into the inside of the tip 31a side of the through-hole 31c of the female member 30. At this time, by pushing in the protrusion 22 of the male member 20, the ball 41 of the engaging portion 40 provided on the protrusion 22 engages with the groove portion 31i of the through-hole 31c of the female member 30, and the fastener 10 is in the connected state shown in FIGS. 1 and 3. As a result, both ends of the string-like body 11 are closed, and the string-like body 11 becomes annular. At this time, as shown in FIGS. FIG. 1 and FIG. 3, the tip 21a of the body portion 21 of the male member 20 and the tip 31a of the body portion 31 of the female member 30 are in contact with each other, and the protrusion 22 is not visible from the outside.

[0029] 1 and 3, the male member 20 and the female member 30 are separated by removing the tip 22a side of the protrusion 22 of the male member 20 from the inside of the tip 31a side of the through-hole 31c of the female member 30. At this time, by pulling out the male member 20, the ball 41 of the engaging portion 40 retreats to the inside of the recess 42 against the biasing force of the spring 43, and the engagement between the ball 41 and the inner wall surface of the groove portion 31i of the through-hole 31c of the female member 30 is released, resulting in the separated state of the fastener 10 shown in FIGS. 2 and 4. As a result, both ends of the string-like body 11 open, and the string-like body 11 becomes linear.

[0030] A metal tube 12 is attached to the end of the string-like body 11. The tube 12 is fitted onto the end of the string-like body 11, and the tube 12 is compressed from above and below to deform its cross-sectional shape into an ellipse, thereby fixing the tube 12 to the end of the string-like body 11. The width of the string-like body 11 is smaller than the inner diameter D13 of the small diameter portion 21f of the through hole 21c of the male member 20 and the inner diameter D33 of the small diameter portion 31f of the through hole 31c of the female member 30. Therefore, the string-like body 11 can pass through the inside of the through hole 21c of the male member 20 and the inside of the through hole 31c of the female member 30.

[0031] On the other hand, the width of the tube 12 attached to the end of the string-like body 11 is larger than the inner diameter D13 of the small diameter portion 21f of the through hole 21c of the male member 20 and the inner diameter D33 of the small diameter portion 31f of the through hole 31c of the female member 30. Also, the width of the tube 12 at the end of the string-like body 11 is smaller than the inner diameter D12 of the medium diameter portion 21e of the through hole 21c of the male member 20 and the inner diameter D32 of the medium diameter portion 31e of the through hole 31c of the female member 30. Therefore, the tube 12 at the end of the string-like body 11 cannot pass through the inside of the through hole 21c of the male member 20, and the tube 12 gets caught on the inclined portion 21h between the medium diameter portion 21e and the small diameter portion 21f (see FIGS. 3 and 4). The tube 12 getting caught on the inclined portion 21h of the through hole 21c of the male member 20 prevents one end of the string-like body 11 from slipping off the male member 20. Furthermore, the tube 12 at the end of the string-like body 11 cannot pass through the inside of the through-hole 31c of the female member 30, and the tube 12 is caught on the inclined portion 31h between the medium diameter portion 31e and the small diameter portion 31f (see FIGS. 3 and 4). The tube 12 is caught on the inclined portion 31h of the through-hole 31c of the female member 30, which prevents the other end of the string-like body 11 from slipping off the female member 20.

[0032] In this way, by providing the inclined portions 21h, 31h in the through holes 21c, 31c of the trunk portions 21, 31, the fastener 10 can be easily attached to the string-like body 11. In detail, when attaching the fastener 10 to the string-like body 11, one end of the string-like body 11 is inserted into the through hole 21c of the trunk portion 21 of the male member 20 from the small diameter portion 21b side of the end 21b, and the tube 12 is attached to one end of the string-like body 11, and the other end of the string-like body 11 is inserted into the through hole 31c of the trunk portion 31 of the female member 30 from the small diameter portion 31b side of the end 31b, and the tube 12 is attached to the other end of the string-like body 11. Thereafter, by connecting the protrusion 22 to the trunk portion 21 of the male member 20, the fastener 10 can be easily attached to the string-like body 11.

[0033] In this embodiment, as described above, in the fastener 10 which comprises the male member 20 and the female member 30 and is used to open and close both ends of the string-like body 11, the male member 20 is configured such that the body 21 having the through hole 21c extending along the longitudinal direction and the protrusion 22 having the engagement portion 40 are integrally joined together, and the female member 30 comprises the body (second body) 31 having the through hole (second through hole) 31c extending along the longitudinal direction, and the engagement portion 40 comprises a ball 41, a recess 42 which accommodates the ball 41, and a spring 43 which biases the ball 41 outward from the recess 42, and when the protrusion 22 of the male member 20 is inserted into the through hole 31c of the female member 30, the male member 20 and the female member 30 are connected to each other, and in this connected state, the ball 41 is engaged with the inner wall surface of the groove portion 31i formed on the inner wall surface of the through hole 31c of the female member 30 by the biasing force of the spring 43.

[0034] According to this embodiment, the male member 20 and the female member 30 can be easily connected and deterioration of the male member 20 and the female member 30 can be suppressed. Specifically, when connecting the male member 20 and the female member 30, the protrusion 22 of the male member 20 is pushed into the through-hole 31c of the female member 30, causing the ball 41 of the engagement portion 40 provided on the protrusion 22 to engage with the groove 31i of the through-hole 31c of the female member 30. When the fastener 10 is in a connected state, the ball 41, biased by the spring 43 of the engagement portion 40, is engaged with the inner wall surface of the groove 31i of the through-hole 31c of the female member 30, so that the connection between the male member 20 and the female member 30 is not easily released. This makes it possible to easily connect the male member 20 and the female member 30 and to easily maintain the connected state of the male member 20 and the female member 30.

[0035] On the other hand, when disconnecting the male member 20 and the female member 30, the protrusion 22 of the male member 20 is pulled out of the through-hole 31c of the female member 30. At this time, the ball 41 of the engagement portion 40 comes into contact with the periphery of the inner wall surface of the groove portion 31i, and a force acts on the ball 41 in a radially inward direction (toward the interior of the recess 42). As a result, the ball 41 retracts toward the interior of the recess 42 against the biasing force of the spring 43, and the engagement between the ball 41 and the inner wall surface of the groove portion 31i of the through-hole 31c of the female member 30 is released, and the male member 20 and the female member 30 are separated. When the male member 20 and the female member 30 are repeatedly attached and detached, the periphery of the inner wall surface of the groove portion 31i of the through-hole 31c of the female member 30 may gradually wear away. However, because the ball 41 is a stainless steel sphere, it hardly wears away. Therefore, even if the peripheral portion of the inner wall surface of the groove portion 31i of the through hole 31c of the female member 30 is slightly worn, the ball 41 can be reliably engaged with the inner wall surface of the groove portion 31i, and deterioration of the male member 20 and the female member 30 can be suppressed compared to when an elastic material such as rubber is used.

[0036] Furthermore, in this embodiment, the body portion 21 of the male member 20 and the body portion (second body portion) 31 of the female member 30 have the same shape, so the body portion 21 of the male member 20 and the body portion 31 of the female member 30 can be made into the same part. This reduces the number of manufacturing steps for the fastener 10, improving the productivity of the fastener 10. Furthermore, because the protrusion 22 having the engaging portion 40 is a separate part from the body portion 21, it becomes possible to manufacture and manage inventory of the protrusion 22 and the body portion 21 separately.

[0037] A neck strap (see FIGS. 1 to 4) equipped with the above-described fastener 10 also provides the same effects as those of the above-described fastener 10. That is, the ease of connecting the male member 20 and the female member 30 can be ensured, and deterioration of the male member 20 and the female member 30 can be suppressed.

[0038] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention should not be interpreted solely by the above-described embodiments, but should be defined by the claims. Furthermore, all modifications within the scope and meaning equivalent to the claims are included.

[0039] The shapes of the body portion 21 and protrusion 22 of the male member 20 and the body portion 31 of the female member 30 described above are merely examples and can be modified in various ways. For example, the through hole 21c of the body portion 21 of the male member 20 and the through hole 31c of the body portion 31 of the female member 30 may be shaped so as not to have medium diameter portions 21e, 31e. The inclined portions 21g, 21h of the through hole 21c of the body portion 21 of the male member 20 and the inclined portions 31g, 31h of the through hole 31c of the body portion 31 of the female member 30 may be omitted, and the through hole 21c of the body portion 21 of the male member 20 and the through hole 31c of the body portion 31 of the female member 30 may be shaped so as to have a vertically stepped surface.
