Description

Male member for buckle, buckle, and method for attaching and detaching female member

[0001] The present invention relates to a male member for a buckle that enables a female member to reciprocate and be detachable. The present invention also relates to a buckle including the male member and the female member. The present invention further relates to a method for attaching and detaching the female member.

[0002] An example of a buckle includes a male member and a female member (Patent Document 1). The male member is in a band shape and has an engaged portion at one end in the width direction of the band. The engaged portion extends along the longitudinal direction of the band. The female member has an engaging portion. The engaging portion is a pair of clamping pieces. When the pair of clamping pieces clamp the engaged portion, the engaging portion and the engaged portion are connected. In this connected state, the female member can reciprocate with respect to the male member. The direction in which the female member reciprocates with respect to the male member is the direction in which the engaged portion extends. On the other hand, when the female member is moved in the width direction of the band of the male member in this connected state, the pair of clamping pieces elastically deform, and the engaging portion and the engaged portion are separated. That is, the direction in which the female member is attached to and detached from the male member is different from the direction in which the engaged portion extends.

[0003] Japanese Patent No. 6125395

[0004] The present invention has a configuration different from the above-described configuration, and aims to enable a female member to reciprocate and be detachable with respect to a male member.

[0005] The male member for a buckle according to the present invention enables a female member including a female portion to reciprocate and be detachable. The male member includes a male portion that guides the female portion and a fin portion that projects from the male portion. The male portion includes a first male portion that extends in a first direction and guides the female portion to reciprocate, and a second male portion that extends from the first male portion. The second male portion includes a male leading portion that extends from the tip of the second male portion toward the first male portion. Assuming that the direction in which the male portion guides the female portion to reciprocate is defined as the first direction, and when it is assumed that the first male portion extends along the first direction from the end toward the second male portion, a direction different from the extending direction is defined as the second direction. The male leading portion extends in a second direction different from the first direction and guides the female portion to be insertable and removable in the second direction.

[0006] The shape of the second male part is irrelevant. To make the reciprocating and attachment / detachment operations of the female member easier to understand, it is desirable to do the following: When viewed from the thickness direction of the fin, the second male part should have a different shape from the first male part.

[0007] The specific shape of the fin portion is preferably as follows: The fin portion comprises a band portion adjacent to the male portion and serving as a passage area for the female portion, and a projection portion extending from the band portion on the opposite side from the male portion. The band portion extends in a first direction along the first male portion and in a second direction along the male tip portion.

[0008] When viewed from the thickness direction, the relative positions of inside and outside refer to the position of the fin portion being inside and the position of the male portion being outside in the case of the male portion and the fin portion. The line extending from the inner edge of the first male portion toward the second male portion is defined as the extended inner line. It does not matter whether the male tip portion is located inside or outside the extended inner line. To facilitate the attachment and detachment of the female member, it is desirable to do the following: The male tip portion should be located away from the extended inner line.

[0009] When viewed from the thickness direction, it is not important whether the boundary between the outer edge of the second male part and the outer edge of the first male part is clear or unclear. When viewed from the thickness direction, it is desirable to make it easier to grasp the position where the reciprocating operation and attachment / detachment operation of the female member are switched, as follows: When viewed from the thickness direction, the outer edge of the second male part is positioned inward in a stepped manner relative to the outer edge of the first male part at the boundary with the first male part.

[0010] The line extending from the outer edge of the first male part toward the second male part is defined as the extended outer line. When the outer edge of the second male part is stepped as described above, it is not necessary whether the outer edge of the second male part is parallel to the inside of the extended outer line. To facilitate the guidance of the female part in the second direction by the second male part, it is desirable to do the following: The outer edge of the second male part should approach the extended outer line as it approaches the tip of the second male part.

[0011] The second male part may or may not consist solely of a male tip. To facilitate the change of orientation of the female member between the first and second directions, it is desirable to do the following: The second male part includes a male tip and a connecting section that connects the male tip and the first male part. The inner edge of the connecting section should coincide with the extended inner line.

[0012] The buckle of the present invention comprises a male member and a female member. The female member includes a female portion that is guided along the male part.

[0013] Whether or not the reciprocating range of the female member is defined is irrelevant. To define the reciprocating range, it is desirable to provide a stopper. The stopper may be provided on the object to which the male member is attached, or on the male member. To make it easier to change the reciprocating operation and attachment / detachment operation of the female member, it is desirable to do the following: The male member is provided with a first stopper that rises from the fin portion at a distance from the male tip portion and into which the female member can collide. The passage area of ​​the female member comprises a reciprocating area along the first male portion and an attachment / detachment area along the male tip portion. One end of the reciprocating area is formed by the first stopper. The attachment / detachment area is formed between the male tip portion and the first stopper.

[0014] When changing the position of the female member from one aligned with a first direction to one aligned with a second direction, it is desirable to stabilize it in the position aligned with the first direction before the change. When the female part is guided by the first male part and viewed from the first direction, the female part has a mouth that clamps the fin part from the thickness direction. The male member has a posture-holding part that protrudes from the fin part on the inside of the reciprocating region and is capable of holding the female member in at least one position. When the female member is in the position aligned with the first direction, the posture-holding part is located inside the mouth and restricts the mouth from moving inward. When the female member changes from the position aligned with the first direction to the position aligned with the second direction, the mouth can widen its opening width and at least ride up over the posture-holding part.

[0015] When the female member changes from an orientation along the first direction to an orientation along the second direction, the mouth portion may be in a state where it is resting on the orientation-holding portion. In order for the orientation-holding portion to stably hold the female member in both the orientation along the first direction and the orientation along the second direction, it is desirable that the mouth portion be able to move over the orientation-holding portion in both inward and outward directions. The orientation-holding portion is capable of holding the female member in both orientations. When the female member is in an orientation along the second direction, the orientation-holding portion is located inside the female member but outside the mouth portion, restricting the mouth portion from moving outward.

[0016] The positional relationship between the first stopper and the posture-holding part is preferably as follows in order to facilitate changing the position of the female member from a position along the first direction to a position along the second direction: When the female member collides with the first stopper, the posture-holding part is positioned inward relative to the opening, thereby restricting the opening from moving inward.

[0017] The reciprocating region does not need to be planar or not. To position the female member in the reciprocating region, it is desirable to do the following: The male member has multiple protrusions that rise from the fin portion at intervals in a first direction and divide the reciprocating region into sections shorter than the reciprocating region. The mouth portion is restricted from moving in the first direction by the protrusions and is able to overcome the protrusions. Adjacent protrusions should be able to be adjacent to both ends of the mouth portion in the first direction.

[0018] The present invention relates to a method for attaching and detaching a female member, and is based on a product comprising a male member, a female member that can reciprocate relative to the male member, an object to which the male member is attached, and a first stopper and a second stopper that define the reciprocating range of the female member. The male member comprises a male part and a fin part extending from the male part. The fin part comprises a band portion adjacent to the male part and thinner than the male part, and a protruding part extending from the band portion on the opposite side from the male part. The male part comprises a first male part that guides the female part to reciprocate, and a second male part extending from the first male part. The second male part comprises a male tip portion extending from the tip of the second male part toward the first male part, and a relay portion that connects the male tip portion and the first male part. The direction in which the male part guides the female part so that it can reciprocate is defined as the first direction, and assuming that the first male part extends from the end toward the second male part along the first direction, the direction different from the direction of said extension is defined as the second direction. The second male tip extends in the second direction. The female member comprises a female part guided along the male part and an operating part protruding from the female part. Inside the female part, a passage for the male part and a fin groove for the fin part are formed. The band portion becomes the passage region of the female part, and the passage region comprises a reciprocating region along the first male part and an attachment / detachment region along the male tip. The attachment / detachment method of the present invention is based on the above product and involves inserting and removing the female member from the male tip in the second direction.

[0019] The method for attaching and detaching the female member of the present invention preferably further comprises the following configuration to the above-described product. When the female part is guided by the first male part and viewed from the first direction, the female part has a mouth that clamps the band. The male part has a posture-holding part that protrudes from the protruding part on the inside of the reciprocating region and is capable of holding the female member in two positions. When the female member is in a position along the first direction, the posture-holding part is located inside the mouth and restricts the mouth from moving inward. When the female member is in a position along the second direction, the posture-holding part is located inside the female part and outside the mouth and restricts the mouth from moving outward. Based on the above product, the method for attaching and detaching the female member of the present invention, when the female member changes from one position along the first direction or the second direction to the other, causes the mouth to move over the posture-holding part by elastic deformation of at least one of the mouth and the posture-holding part. Elastic deformation of the mouth means that the mouth widens its opening width. Elastic deformation of the posture-holding part means that the amount of protrusion relative to the protruding part decreases as the posture-holding part collapses.

[0020] The method for attaching and detaching the female member of the present invention preferably includes the following additional configuration to the above-described product. The outer edge of the second male part is positioned inward in a stepped manner relative to the outer edge of the first male part at the boundary with the first male part. The boundary between the first male part and the second male part is a stepped portion. The inner edge of the intermediate portion coincides with the extended inner line. The attachment / detachment area is formed between the male tip and the first stopper. The method for attaching and detaching the female member of the present invention preferably assumes the above-described product. When attaching the female member, the female member is moved in the second direction to pass the female part through the male tip, and then the female member is pulled outward so that the opening passes over the posture-holding portion and the female member is in a posture aligned with the first direction. To remove the female member from the position where it is located on the first male part, the female member is moved along the first direction toward the second male part, and then pushed inward so that the opening overcomes the posture-holding part and the female member is in a position aligned with the second direction. Then, the female member is moved in the second direction away from the first male part, thereby being pulled out from the male tip.

[0021] According to the present invention, the direction in which the female member reciprocates coincides with the direction in which the first male part extends, i.e., the first direction, and the direction in which the female member can be inserted and removed coincides with the direction in which the male tip extends, i.e., the second direction. As a result, the female member can reciprocate and be attached and detached only in the direction in which the male part extends.

[0022] This is a perspective view showing the buckle of the first embodiment. Figures (A) to (C) are a plan view, front view, and rear view showing the male member. Figures (D) and (E) are a right side view and left side view showing the male member in a more enlarged view than in Figure 2. Figures (F) to (I) are cross-sectional views taken along lines F-F, G-G, H-H, and I-I in Figure 2. Figures (A) to (C) are a plan view, right side view, and cross-sectional view taken along line C-C in Figure 5(A) showing the first stage of the female member attachment procedure. Figures (A) to (C) are a plan view, right side view, and cross-sectional view taken along line C-C in Figure 6(A) showing the second stage of the female member attachment procedure. Figures (A) to (C) are a plan view, right side view, and cross-sectional view taken along line C-C in Figure 7(A) showing the third stage of the female member attachment procedure. This is a plan view showing the stage after the female member has been attached and moved in the first direction. This is a plan view showing the first stage of the female member removal procedure.

[0023] The buckle of the first embodiment comprises a male member 1 and a female member 9, as shown in Figures 1, 5 to 9. The female member 9 comprises a female portion 91 and an operating portion 93 protruding from the female portion 91. The male member 1 comprises a male portion 2 and a fin portion 3 protruding from the male portion 2. The male portion 2 and the female portion 91 are a sliding pair. The buckle is attached to an object. The object is, for example, a shoulder strap of a backpack or a part of a bag. Backpacks and bags are the products referred to in this invention.

[0024] The female portion 91 is slidably guided by the male portion 2. Inside the female portion 91, a passage 91a for the male portion 2 and a fin groove 91b for the fin portion 3 are formed. The passage 91a extends in a straight line and penetrates the female portion 91. The fin groove 91b connects the external space of the female portion 91 with the passage 91a and is formed along the passage 91a. When viewed from the direction in which the passage 91a penetrates, the female portion 91 is C-shaped. When viewed from the direction in which the passage 91a penetrates, the female portion 91 comprises an opening 91c that forms the fin groove 91b and a female body portion 91d that forms the passage 91a. The opening 91c has a surface that is aligned with the depth direction of the fin groove 91b. When viewed from the direction of passage 91a, the opening width (minimum value) of the mouth portion 91c (fin groove 91b) is shorter than the width (maximum value) of the female body portion 91d (passage 91a). The mouth portion 91c sandwiches the fin portion 3 from the thickness direction.

[0025] The operating section 93 extends from the outer surface of the female section 91. The operating section 93 extends along the direction of passage 91a. The operating section 93 is located on the outer surface of the female section 91 on the side opposite to the fin groove 91b. The operating section 93 is plate-shaped. When viewed from the direction of passage 91a, the thickness direction of the operating section 93 coincides with the width direction of the opening 91c. The operating section 93 has a through hole 93a that penetrates in the thickness direction. For example, a tape is passed through the through hole 93a.

[0026] As shown in Figures 1 to 3, the male part 2 comprises a first male part 21 that guides the female part 91 so that it can reciprocate, and a second male part 22 that extends from the first male part 21 and guides the female part 91 so that it can be inserted into and removed. With respect to the direction in which the male part 2 extends, the second male part 22 forms one side of the male part 2, and the first male part 21 forms the other side of the male part 2. In other words, with respect to the direction in which the male part 2 extends, the first male part 21 and the second male part 22 are located on opposite sides of each other.

[0027] The second male part 22 includes a male tip 23 located at one end of the male part 2, and a relay part 24 that connects the male tip 23 and the first male part 21.

[0028] The fin portion 3 is plate-shaped. The fin portion 3 comprises a band portion 31 which is the passage area for the female portion 91 (mouth portion 91c), and a protruding portion 32 which extends from the band portion 31 to the opposite side from the male portion 2. The band portion 31 is adjacent to the male portion 2. The band portion 31 has a length direction, a width direction, and a thickness direction. The length direction is the direction in which the male portion 2 extends. The width direction is the direction in which it protrudes from the male portion 2. The thickness direction is perpendicular to the width direction and the length direction. The passage area comprises a reciprocating area 31a and an attachment / detachment area 31b. The reciprocating area 31a is along the first male portion 21 and the intermediate portion 24. The attachment / detachment area 31b is along the male tip portion 23. The protruding portion 32 can be attached to an object. The protruding portion 32 can be attached to an object, for example, by sewing.

[0029] Figure 2(A) shows the male member 1 placed on a flat surface. Based on Figure 2(A), the directions are defined as follows: The direction in which the first male part 21 extends is the first direction d1. The direction in which the intermediate part 24 extends at the boundary with the fin part 3 is the first direction. The first direction d1 is the direction in which the female member 9 reciprocates. In other words, the first direction d1 is the direction in which the male part 2 guides the female part 91 so that it can reciprocate. In this embodiment, the first direction d1 is arc-shaped. The first male part 21 is arc-shaped. The arc of the first male part 21 extends to the left and right and bulges upward. That is, the center of the arc of the first male part 21 is located below the first male part 21. The direction in which the male tip part 23 extends is the second direction d2, which is different from the first direction d1. The second direction d2 is substantially inclined with respect to the first direction d1. In this embodiment, since the first direction d1 is an arc, it is inclined with respect to the tangential direction to the endpoint of the arc. The second direction d2 is the direction in which the female member 9 is inserted and removed. In other words, the second direction d2 is a different direction from the direction in which the first male part 21 extends from the end of the second male part 22 along the first direction d1. In this embodiment, the second direction d2 is linear. The second direction d2 is inclined with respect to the left-right direction in Figure 2(A). The second direction d2 is upward as it moves to the right.

[0030] The inward / outward direction d3 indicates the relative positional relationship. The inward direction, for the first male part 21 and fin part 3, substantially coincides with the downward direction in Figure 2(A). The outward direction, for the first male part 21 and fin part 3, substantially coincides with the upward direction in Figure 2(A). The inward / outward direction d3 coincides with the width direction of the band part 31. In the case of the male part 2 and fin part 3, the inward direction is the position of the fin part 3, and the outward direction is the position of the male part 2.

[0031] The thickness direction d4 is the direction perpendicular to the plane of the paper in Figure 2(A). The thickness direction d4 is also called the front-to-back direction. The front direction is the direction facing the viewer, perpendicular to the plane of the paper in Figure 2(A). The back direction is the direction facing the back, perpendicular to the plane of the paper in Figure 2(A). When viewed from the thickness direction d4, the male part 2 has an inner edge and an outer edge. The inner edge is the boundary between the male part 2 and the fin part 3. The outer edge is the edge opposite to the inner edge. The line extending the inner edge 21L1 of the first male part 21 toward the second male part 22 is defined as the extended inner line L1. The line extending the outer edge 21L2 of the first male part 21 toward the second male part 22 is defined as the extended outer line L2.

[0032] Both the first male part 21 and the second male part 22 are raised in the front-back direction relative to the fin part 3. The outer surface of the first male part 21 is a cylindrical surface curved in an arc shape. When the first male part 21 is cut in the thickness direction d4, the cross-sectional shape of the first male part 21 is circular. The outer surface of the first male part 21 faces the inner surface of the female part 91. When the female part 91 is moved back and forth in the first direction d1, the inner surface of the first male part 21 rubs against the inner surface of the female part 91.

[0033] When viewed from the thickness direction d4, the second male part 22 has a different shape from the first male part 21. The outer edge 22L2 of the second male part 22 is located inward in a stepped manner relative to the outer edge 21L2 of the first male part 21 at the boundary with the first male part 21. The boundary between the first male part 21 and the second male part 22 is a stepped portion 25. The width of the second male part 22 is shorter than the width of the first male part 21. The outer edge 22L2 of the second male part 22 is located inward from the extension line L2. The outer edge 22L2 of the second male part 22 approaches the extension line L2 as it moves away from the first male part 21. Specifically, the outer edge 24L2 of the relay portion 24 approaches the extension line L2 as it moves away from the first male part 21. The outer edge 23L2 of the male tip portion 23 approaches the extension line L2 as it moves away from the first male portion 21, and then moves away from it. The outer edge 23L2 of the male tip portion 23 has a curved shape. The male tip portion 23 is located outward from the extension line L1. The inner edge 23L1 of the male tip portion 23 moves outward from the extension line L1 as it moves away from the first male portion 21. The inner edge 24L1 of the relay portion 24 coincides with the extension line L1.

[0034] In addition to the male part 2 and the fin part 3, the male member 1 includes a first stopper 4 and a second stopper 5 that define both ends of the reciprocating region 31a, a plurality of protrusions 6 that divide the reciprocating region 31a into sections shorter than the reciprocating region 31a, and a posture holding part 7 that can hold the female member 9 in two positions. The male member 1 is symmetrical on both sides.

[0035] The first stopper 4 defines one end of the reciprocating region 31a. The first stopper 4 protrudes from the fin portion 3 on one end in the direction in which the male portion 2 extends. More specifically, the first stopper 4 protrudes from the protruding portion 32 in both the front and back directions. The first stopper 4 is positioned with a gap inward relative to the male tip portion 23. A detachable region 31b is formed between the first stopper 4 and the male tip portion 23, through which the mouth portion 91c passes. When the mouth portion 91c passes through the detachable region 31b, the first stopper 4 is positioned inward relative to the mouth portion 91c. Inward relative to the mouth portion 91c refers to the passage 91a of the male portion 2. When the mouth portion 91c moves through the reciprocating region 31a and collides with the first stopper 4, the female member 9 is positioned at one end of the reciprocating region 31a.

[0036] The second stopper 5 defines the other end of the reciprocating region 31a. The second stopper 5 protrudes from the outer surface of the male part 2 at the other end in the direction in which the male part 2 extends (the left end in Figure 2(A)). The second stopper 5 is formed at the other end of the first male part 21, on the opposite side from the second male part 22.

[0037] The protrusions 6 rise from the reciprocating region 31a of the band portion 31 in the front and back directions. The spacing between adjacent protrusions 6 substantially coincides with the dimensions of the opening portion 91c (the dimensions in the through-direction of the passage 91a).

[0038] The posture-holding portion 7 protrudes inward from the fin portion 3 in the portion of the reciprocating region 31a that is along the intermediate portion 24. More specifically, the posture-holding portion 7 protrudes in the front and back directions from the protruding portion 32. When the mouth portion 91c collides with the first stopper 4, the female member 9 is in a position along the first direction d1. In this case, the posture-holding portion 7 is located inward from the mouth portion 91c and restricts the inward movement of the mouth portion 91c.

[0039] As shown in Figures 2 and 4, the thickness of the male member 1 includes the thickness t1 of the first male part 21, the thickness t2 of the intermediate part 24, the thickness t3 of the male tip part 23, the thickness t4 of the posture holding part 7, the thickness t5 of the first stopper 4, the thickness t6 of the second stopper 5, the thickness t7 of the convex part 6, the thickness t8 of the band part 31, and the thickness t9 of the protruding part 32.

[0040] The thickness of the male part 2 (t1, t2, t3), the thickness of the posture holding part 7 (t4), the thickness of the first stopper 4 (t5), the thickness of the second stopper 5 (t6), and the thickness of the protrusion 6 (t7) are all greater than the thickness of the band part 31 (t8). t1 to t7 > t8. The thickness of the male part 2 (t1, t2, t3), the thickness of the first stopper 4 (t5), and the thickness of the second stopper 5 (t6) are all greater than the thickness of the posture holding part 7 (t4) and the thickness of the protrusion 6 (t7). t1 to t3, t5, t6 > t4, t7. The thickness of the band part 31 (t8) is greater than the thickness of the protruding part 32 (t9). t8 > t9. The thickness of the first male part 21 (t1) and the thickness of the male tip part 23 (t3) are greater than the thickness of the intermediate part 24 (t1, t3 > t2). The thickness t2 of the intermediate section 24 increases from the first male part 21 toward the male tip part 23. The thickness t1 of the first male part 21 is the same as the thickness t3 of the male tip part 23. t1 = t3.

[0041] The male member 1 and the female member 9 are made of, for example, synthetic resin. The female part 91 is elastically deformable, and the opening width of the mouth 91c expands due to the elastic deformation of the mouth 91c and returns to its original size upon restoration. The opening width of the mouth 91c expands to the same dimension as the thickness t7 of the protrusion 6 and the thickness t4 of the posture-holding part 7 due to the elastic deformation, and returns to less than the thickness t7 of the protrusion 6 and the thickness t4 of the posture-holding part 7. If the mouth 91c does not elastically deform, the mouth 91c collides with the protrusion 6 or the posture-holding part 7 and its movement is restricted, making it impossible to pass through the protrusion 6 or the posture-holding part 7. If the mouth 91c elastically deforms, the mouth 91c can pass over the protrusion 6 or the posture-holding part 7. When the mouth 91c passes over the posture-holding part 7 or the protrusion 6, a force is applied to the male member 1 from the mouth 91c, but the male member 1 has sufficient rigidity to withstand that force. On the other hand, even if the opening 91c undergoes elastic deformation, the opening 91c cannot pass through the male part 2 in the inward / outward direction d3, and the opening 91c cannot pass through the first stopper 4 and the second stopper 5 in the first direction d1.

[0042] The method for attaching and detaching the female member 9 is to insert and remove the female member 9 from the male tip portion 23 in the second direction d2. In detail, the procedure for attaching the female member 9 is as follows: 1) As shown in Figure 5, the female member 9 is moved from right to left along the second direction d2, and the female portion 91 is passed through the male tip portion 23 from one side in the direction of passage 91a. When this is done, the male tip portion 23 is housed inside the female body portion 91d, and the first stopper 4 is positioned inward relative to the opening portion 91c. The female member 9 is also in a position along the second direction d2. 2) As shown in Figure 6, when the female member 9 is moved further to the left along the second direction d2, the opening portion 91c is guided in the second direction d2 by the male tip portion 23 and the first stopper 4, the female portion 91 collides with the stepped portion 25, and the female member 9 stops. When stopped, the posture-holding part 7 is located inside the female part 91 and outside the mouth part 91c, restricting the mouth part 91c from moving outward. Also, when stopped, the relay part 24 and the posture-holding part 7 are housed inside the female body part 91d near the stepped part 25, preventing the female part 91 from moving inward. As a result, the female member 9 is held in a posture along the second direction d2. 3) As shown in Figure 7, when the female member 9 is pulled outward near the stepped part 25, the mouth part 91c returns to its original position by elastic deformation, overcoming the posture-holding part 7. As a result, the female member 9 takes a posture along the first direction d1. The posture-holding part 7 is located inside the mouth part 91c, restricting the mouth part 91c from moving inward. In this case, the mouth part 91c can move to the left. However, the rightmost convex part 6 is located to the left of the mouth part 91c and restricts the mouth part 91c from moving to the left. 4) When the female member 9 is moved further to the left along the first direction d1, the mouth portion 91c returns to its original position by elastic deformation, overcoming the rightmost protrusion 6, and colliding with another protrusion 6 as shown in Figure 8. As a result, the female member 9 stops in a position on the first male portion 21, with protrusions 6 adjacent to both the left and right ends of the mouth portion 91c (both ends in the first direction d1). In other words, the female member 9 is positioned in the first direction d1.

[0043] The procedure for removing the female member 9 is as follows in 5) to 7) below. 5) When the female member 9 is moved to the right (towards the second male part 22) along the first direction d1 from the state where it is located at the first male part 21 as shown in FIG. 8, the mouth part 91c elastically deforms to overcome the rightmost convex part 6 and then restores, and collides with the first stopper 4 as shown in FIG. 9. In this case, the posture holding part 7 is located inside with respect to the mouth part 91c and restricts the inward movement of the mouth part 91c. 6) When the female member 9 is pushed inward, the mouth part 91c elastically deforms to overcome the posture holding part 7 and then restores. In this case, as shown in FIG. 6, the female member 9 takes a posture along the second direction d2. Note that the posture holding part 7 is inside the female part 91 and is located outside with respect to the mouth part 91c, and restricts the outward movement of the mouth part 91c. 7) When the female member 9 is further moved to the right (away from the first male part 21) along the second direction d2, the female part 91 is pulled out from the male tip part 23, and the female member 9 is removed from the male member 1.

[0044] According to the present embodiment, the direction in which the female member 9 reciprocates coincides with the direction in which the first male part 21 extends, that is, the first direction d1, and the direction in which the female member 9 can be inserted and removed coincides with the direction in which the male tip part 23 extends, that is, the second direction d2. As a result, only in the direction in which the male part 2 extends, the female member 9 can reciprocate and can be inserted and removed. And since the tip of the male tip part 23 is exposed to the space, it can be understood that the female part 91 can be inserted and removed from the male tip part 23.

[0045] When viewed from the thickness direction d4, since the second male part 22 has a different shape from the first male part 21, it is easy to understand that the female member 9 can move in a different direction from the first male part 21 at the second male part 22. As a result, it is easy to understand the reciprocating operation and the attaching / detaching operation of the female member 9.

[0046] Since the fin part 3 includes the belt part 31 and the belt part 31 extends along the male tip part 23 in the second direction d2, it is easy to understand that if the female member 9 is moved in the second direction d2, it can be inserted and removed from the male member 1. As a result, it is easy to operate the female member 9.

[0047] Since the male leading part 23 is located outside and away from the extension inner wire L1, it is easy to understand that when removing the female member 9 from the state where the female member 9 is reciprocally guided by the male part 2, the female member 9 may be moved outside with respect to the extension inner wire L1. As a result, the female member 9 is easy to operate.

[0048] Since the outer edge 22L2 of the second male part 22 is located inside in a step shape with respect to the outer edge 21L2 of the first male part 21 at the boundary with the first male part 21, it is easy to grasp the position for switching between the reciprocating operation and the attaching / detaching operation of the female member 9. As a result, the female member 9 is easy to operate.

[0049] Since the outer edge 22L2 of the second male part 22 approaches the extension outer wire L2 as it goes toward the tip of the second male part 22, for example, compared with the case where the outer edge 22L2 of the second male part 22 is parallel inside with respect to the extension outer wire L2, the width can be increased as the male leading part 23 goes forward, and it is easy to guide the female part 91 with the male leading part 23 in a posture along the second direction d2. Further, since the male leading part 23 is located between the extension inner wire L1 and the extension outer wire L2, the dimension of the male member 1 in the inner-outer direction d3 becomes short. [[ID=�]]

[0050] Since the inner edge 24L1 of the relay part 24 coincides with the extension inner wire L, the female member 9 can reciprocate within the range of the first male part 21 and the relay part 24. Further, the female member 9 can be inserted and removed within the range of the relay part 24 and the male leading part 23. The female member 9 can be easily changed between the posture along the first direction d1 and the posture along the second direction d2 by the relay part 24.

[0051] Since the male member 1 includes the first stopper 4, when the female member 9 is moved in the first direction d1 by a reciprocating operation and collided with the first stopper 4, it cannot move further in the same direction. As a result, it is easy to understand that the female member 9 may be moved in the second direction d2 and removed, and it is easy to change from the reciprocating operation to the removing operation.

[0052] Since the female member 9 includes the posture holding part 7 and the posture holding part 7 holds the female member 9 in the posture along the first direction d1 and the posture along the second direction d2, the posture of the female member 9 is stabilized depending on whether the mouth part 91c is located inside or outside with respect to the posture holding part 7. As a result, the female member 9 is easy to guide in the first direction d1 and the second direction d2.

[0053] When the female member 9 collides with the first stopper 4 in the reciprocating region 31a, the posture holding portion 7 is positioned inward relative to the mouth portion 91c, and the posture holding portion 7 restricts the inward movement of the mouth portion 91c. As a result, the female member 9 stabilizes in a posture along the first direction d1.

[0054] Since the male member 1 has a protrusion 6, the female member 9 is restricted from moving in the first direction d1 by the protrusion 6. Moreover, when the mouth portion 91c is located between adjacent protrusions 6, the protrusions 6 are adjacent to both ends of the mouth portion 91c in the first direction d1, thus positioning the female member 9.

[0055] The present invention is not limited to the embodiments described above. For example, in the above embodiments, the first direction d1 was a direction of curvature in an arc, but the present invention is not limited to this and may be a linear direction.

[0056] In the above embodiment, the male member 1 was symmetrical on both sides, but the present invention is not limited to this and may be asymmetrical on both sides. Specifically, in the above embodiment, the convex portion 6, the first stopper 4, and the posture holding portion 7 were raised in the front and back directions of the fin portion 3, but the present invention is not limited to this and may be raised only in the front or back direction of the fin portion 3.

[0057] In the above embodiment, the fin portion 3 was a plate without holes, but in the present invention, it is not limited to this, and may be a plate with through holes formed therein. Also, in the above embodiment, the inner edge of the fin portion 3 was arc-shaped, but in the present invention, it is not limited to this, and may be a corrugated or uneven shape, or other shapes.

[0058] In the above embodiment, the male part 2 comprised only the first male part 21 and the second male part 22. However, the present invention is not limited to this, and may also comprise one or more third male parts having substantially the same configuration as the second male part 22, or a fourth male part having substantially the same configuration as the first male part 21, etc.

[0059] More specifically, in the above embodiment, the male part 2 comprises only a first male part 21 and a second male part 22. Therefore, there is only one attachment / detachment region in the male part 2, and it is formed only in the portion of the second male part 22 that is along the male tip 23.

[0060] For example, if the male part 2 has a first male part 21 and a second male part 22, and also a third male part, the first example is one in which the third male part 3 protrudes from the fin part 3 at a distance in the reciprocating direction on the opposite side of the second male part 22 from the first male part 21. The second example is one in which the third male part 3 protrudes from the fin part 3 at a distance in the reciprocating direction on the opposite side of the first male part 21 from the second male part 22. In this case, there are two attachment / detachment regions, formed in the part along the male tip 23 of the second male part 22 and in the part along the male tip of the third male part.

[0061] Furthermore, if the male part 2 has multiple third male parts in addition to the first male part 21 and the second male part 22, the first example is that the first third male part protrudes from the fin part 3 at a distance in the reciprocating direction on the opposite side of the second male part 22 from the first male part 21, and the second and subsequent third male parts protrude from the fin part 3 at a distance in the reciprocating direction on the opposite side of the first third male part from the second male part 22. Other examples are omitted. In this case, there are multiple attachment / detachment regions, formed in the portion along the male tip portion 23 of the second male part 22 and in the portion along the male tip portion of each third male part.

[0062] Furthermore, if the male part 2 includes a fourth male part in addition to the first male part 21 and the second male part 22, the fourth male part protrudes from the fin part 3 at a distance in the reciprocating direction, on the opposite side of the second male part 22 from the first male part 21.

[0063] In the above embodiment, the first stopper 4 and the second stopper 5 were formed on the male part 2 of the male member 1, but the present invention is not limited to this, and they may also be formed on the fin part 3 of the male member or on the object.
