Description

Technical Field

[0001] This invention relates to a male component for a buckle that enables the female component to reciprocate and can be attached and detached. Additionally, this invention relates to a buckle comprising a male component and a female component. Background Technology

[0002] One example of a buckle includes a male component and a female component (Patent Document 1). The male component is strip-shaped, with a locking portion at one end in the width direction of the strip. The locking portion extends along the length direction of the strip. The female component has a locking portion. The locking portion consists of a pair of clamping tabs. The locking portion is connected by clamping the locking portion with the pair of clamping tabs. In this connected state, the female component can reciprocate relative to the male component. The direction in which the female component reciprocates relative to the male component is the direction in which the locking portion extends. On the other hand, if the female component is moved in the width direction of the male component's strip in this connected state, the pair of clamping tabs elastically deform, and the locking portion and the locking portion separate. That is, the direction in which the female component is attached to or detached from the male component is a different direction from the direction in which the locking portion extends.

[0006] Problems to be solved by utility models

[0007] The purpose of this invention is to enable the female component to reciprocate relative to the male component and to be detached, using a structure different from the one described above.

[0008] Solution for solving the problem

[0009] The male member of this invention enables the female member, which includes the female part, to reciprocate and to be attached and detached. The male member includes a male portion that guides the female part and a finned portion extending from the male portion. The male portion includes a first male portion extending in a first direction and guiding the female part in a reciprocating manner, and a second male portion extending from the first male portion. The second male portion includes a male front end portion extending from the front end of the second male portion toward the side of the first male portion. The direction in which the male portion guides the female part in a reciprocating manner is defined as the first direction. Assuming that the first male portion extends along the first direction from the end portion on the side of the second male portion, a direction different from this extension direction is defined as the second direction. The male front end portion extends in the second direction, different from the first direction, and guides the female part in a manner that allows it to be inserted and removed in the second direction.

[0010] The second male part is not limited to any particular shape. However, to facilitate the reciprocating operation and loading / unloading of the female component, it is preferable to design it as follows: When viewed from the thickness direction of the fin portion, the second male part is designed to have a different shape than the first male part.

[0011] The fin portion is preferably shaped as follows: The fin portion has a band that is adjacent to the male portion and forms the passage area of ​​the female portion, and an extension portion that extends from the band portion to the side opposite to the male portion. The band portion extends along the first male portion in a first direction and along the male front end in a second direction.

[0012] When viewed from the thickness direction, regarding the relative positional relationship between inner and outer, in the case of the male portion and the fin portion, the fin portion is positioned inner and the male portion is positioned outer. Furthermore, the line obtained by extending the inner edge of the first male portion towards the side of the second male portion is defined as the extended inner line.

[0013] The male front end can be located either inside or outside the extended inner line. However, for easy loading and unloading of the female component, it is preferable to design it as follows.

[0014] The male anterior end is located outward relative to the extended inner line.

[0015] When viewed from the thickness direction, the boundary between the outer edge of the second male part and the outer edge of the first male part may be clear or unclear. However, in order to easily grasp the position of the reciprocating operation and loading / unloading operation of the female component when viewed from the thickness direction, it is preferable to set it as follows.

[0016] When viewed from the thickness direction, the outer edge of the second male part is located on the inner side in a stepped manner relative to the outer edge of the first male part at the junction with the first male part.

[0017] The line obtained by extending the outer edge of the first male part towards the second male part is defined as the extended outer line. When the outer edge of the second male part is the aforementioned stepped shape, the outer edge of the second male part may or may not be parallel to the extended outer line on the inner side. However, to facilitate guiding the female part in a posture along the second direction using the second male part, it is preferable that the outer edge of the second male part approaches the extended outer line towards the front end of the second male part.

[0018] It is acceptable whether the second male part is composed solely of the male anterior end. However, to facilitate changes in the female member's posture along the first direction and along the second direction, it is preferable to configure it as follows.

[0019] In addition to the male anterior end, the second male also has a relay section that relays the male anterior end and the first male. The inner edge of the relay section coincides with the extended inner line.

[0020] The buckle of this invention has a male component and a female component. The female component has a female part that is guided along the male component.

[0021] Whether or not the reciprocating range of the female component is specified is not mandatory. However, if the reciprocating range is specified, it is preferable to have a stop. The stop can be provided on the object on which the male component is mounted, or it can be provided on the male component itself. To facilitate changes to the reciprocating operation and loading / unloading operation of the female component, it is preferable to configure it as follows.

[0022] The male member has a first stop that protrudes from the fin portion at a distance from the male's front end and allows the female member to collide with it. The passage area of ​​the female member has a reciprocating area along the first male member and a loading / unloading area along the male's front end. One end of the reciprocating area is formed by the first stop. The loading / unloading area is formed between the male's front end and the first stop.

[0023] When changing the female component from an orientation along the first direction to an orientation along the second direction, it is preferable to stabilize it in the orientation along the first direction before the change, as follows.

[0024] When viewed from the first direction as the female member is guided by the first male member, the female member has a mouth that clamps the fin portion in the thickness direction. The male member has a posture-holding portion that protrudes from the fin portion inside the reciprocating area and is capable of holding the female member in at least one posture. When the female member is in a posture along the first direction, the posture-holding portion is located inside the mouth and restricts the mouth from moving inward. When the female member changes from a posture along the first direction to a posture along the second direction, the mouth can widen its opening width and at least jump onto the posture-holding portion.

[0025] When the female component changes from a posture along the first direction to a posture along the second direction, the mouth can also be in a state of jumping onto the posture holding part. In order for the posture holding part to stably hold the female component in both the posture along the first direction and the posture along the second direction, it is preferable to set it as follows.

[0026] The mouth can pass over the posture-holding part in both inward and outward directions. The posture-holding part can hold the female component in two postures. When the female component is in the posture along the second direction, the posture-holding part is located inside the female component and outside the mouth, restricting the mouth from moving outward.

[0027] In order to easily change the female component from the posture along the first direction to the posture along the second direction, the positional relationship between the first stop and the posture holding part is preferably set as follows.

[0028] When the female component collides with the first stop, the posture holding part is located inside the mouth, restricting the mouth from moving inward.

[0029] It doesn't matter whether the reciprocating area is planar or not. However, to position the female component within the reciprocating area, it is preferable to set it as follows.

[0030] The male member has multiple protrusions that rise from the fin portion at intervals in the first direction and divide the reciprocating region into intervals shorter than the reciprocating region. The opening is restricted from moving in the first direction by the protrusions and can pass over the protrusions. Adjacent protrusions can abut against both ends of the opening in the first direction.

[0031] The method for loading and unloading the female component of this utility model is based on a product comprising a male component, a female component capable of reciprocating relative to the male component, an object on which the male component is mounted, and a first stop and a second stop defining the reciprocating range of the female component. The male component comprises a male portion and a fin portion extending from the male portion. The fin portion comprises a strip portion adjacent to the male portion and thinner than the male portion, and an extension portion extending from the strip portion to the side opposite to the male portion. The male portion comprises a first male portion that guides the female component in a reciprocating manner, and a second male portion extending from the first male portion. The second male portion comprises a male front end portion extending from the front end of the second male portion towards the side of the first male portion, and a relay portion relaying the male front end portion and the first male portion. The direction in which the male portion guides the female component in a reciprocating manner is defined as a first direction. Assuming that the first male portion extends from the end portion on the side of the second male portion along the first direction, a direction different from this extension direction is defined as a second direction. The male front end portion extends in the second direction. The female component includes a female portion guided along the male portion and an operating portion extending from the female portion. Inside the female portion are formed a passageway for the male portion to pass through and a fin groove for the fin portion to pass through. The strip portion serves as the passage area for the female portion, and the passage area includes a reciprocating area along the first male portion and an loading / unloading area along the male front end. The loading / unloading method of this invention, based on the above product, involves inserting and removing the female component relative to the male front end in a second direction.

[0032] The method for loading and unloading the female component of this invention preferably includes the following structure in addition to the aforementioned product. When viewed from a first direction as the female component is guided by a first male component, the female component has a mouth with a clamping strap. The male component has a posture holding portion that protrudes from the protrusion relative to the reciprocating area and is capable of holding the female component in two positions. When the female component is in a position along the first direction, the posture holding portion is located inside the mouth and restricts inward movement of the mouth. When the female component is in a position along the second direction, the posture holding portion is located inside the female component and outside the mouth, restricting outward movement of the mouth. Based on the above product, in the method for loading and unloading the female component of this invention, when the female component changes from one position along the first direction to the other, at least one of the mouth and the posture holding portion elastically deforms, thereby allowing the mouth to pass over the posture holding portion. Elastic deformation of the mouth refers to the mouth widening its opening. Elastic deformation of the posture-holding part refers to the flattening of the posture-holding part, resulting in a smaller bulge relative to the protruding part.

[0033] The method for loading and unloading the female component of this invention preferably includes the following structure in the product described above. The outer edge of the second male component is located on the inner side in a stepped manner relative to the outer edge of the first male component at the junction with the first male component. The junction between the first and second male components is a stepped portion. The inner edge of the relay portion coincides with the extended inner line. The loading and unloading area is formed between the male front end and the first stop member. The method for loading and unloading the female component of this invention is preferably based on the product described above. Furthermore, when the female component is installed, it is moved in the second direction, thereby allowing the male front end to penetrate the female component. Then, the female component is pulled outward, thereby causing the opening to pass over the posture holding portion, and the female component is positioned along the first direction. When the female component is removed from the state where the female component is located in the first male part, the female component is moved along the first direction toward the side of the second male part. Then, the female component is pressed inward, so that the mouth passes over the posture holding part and the female component is in the posture along the second direction. Then, the female component is moved away from the first male part in the second direction, so that the female part is pulled out from the male front end.

[0034] Effects of the utility model

[0035] According to this invention, the direction of the reciprocating motion of the female component is consistent with the direction of extension of the first male part, i.e., the first direction, and the direction in which the female component can be inserted and removed is consistent with the direction of extension of the male front end, i.e., the second direction. As a result, the female component can reciprocate and be installed and removed only in the direction of extension of the male part. Attached Figure Description

Detailed Implementation

[0047] like Figure 1 , 5 As shown in Figures 9-9, the buckle of the first embodiment includes a male member 1 and a female member 9. The female member 9 includes a female portion 91 and an operating portion 93 extending from the female portion 91. The male member 1 includes a male portion 2 and a fin portion 3 extending 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 part of a handbag. Backpacks and handbags are products described in this utility model.

[0048] The female part 91 is guided by the male part 2 in a sliding manner. Inside the female part 91, a passage 91a for the male part 2 to pass through and a fin groove 91b for the fin part 3 to pass through are formed. The passage 91a extends in a straight line, penetrating the female part 91. The fin groove 91b connects the external space of the female part 91 to the passage 91a and is formed along the passage 91a. When viewed from the penetrating direction of the passage 91a, the female part 91 is C-shaped. When viewed from the penetrating direction of the passage 91a, the female part 91 has an opening 91c forming the fin groove 91b and a female body part 91d forming the passage 91a. The opening 91c has a surface along the depth direction of the fin groove 91b. When viewed from the penetrating direction of the passage 91a, the opening width (minimum value) of the opening 91c (fin groove 91b) is shorter than the width (maximum value) of the female body part 91d (passage 91a). The mouth 91c clamps the fin portion 3 from the thickness direction.

[0049] An operating section 93 extends from the outer surface of the female portion 91. The operating section 93 extends along the through direction of the passage 91a. The operating section 93 is located on the side of the outer surface of the female portion 91 opposite to the fin groove 91b. The operating section 93 is plate-shaped. When viewed from the through direction of the passage 91a, the thickness direction of the operating section 93 is aligned with the width direction of the opening 91c. The operating section 93 has a through hole 93a extending through the thickness direction. For example, a strip can be passed through the through hole 93a.

[0050] like Figures 1-3 As shown, the male part 2 includes a first male part 21 that guides the female part 91 in a reciprocating motion and a second male part 22 that extends from the first male part 21 and guides the female part 91 in an insertable / removable manner. In 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. That is, in 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.

[0051] The second male part 22 has a male front end 23 located at one end of the male part 2 and a relay part 24 that relays the male front end 23 and the first male part 21.

[0052] The fin portion 3 is plate-shaped. The fin portion 3 includes a band portion 31 that forms the passage area of ​​the female portion 91 (mouth portion 91c) and a protrusion portion 32 extending from the band portion 31 to the side opposite to 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 extends from the male portion 2. The thickness direction is a direction orthogonal to the width direction and the length direction. The passage area includes a reciprocating area 31a and a loading / unloading area 31b. The reciprocating area 31a runs along the first male portion 21 and the relay portion 24. The loading / unloading area 31b runs along the male front end portion 23. The protrusion portion 32 can be installed on an object. The protrusion portion 32 is installed on the object, for example, by sewing.

[0053] Figure 2 (A) indicates the state in which male component 1 is placed on the plane. Figure 2 Based on (A), the direction is specified as follows.

[0054] The direction in which the first male part 21 extends is the first direction d1. The direction in which the relay part 24 extends at the junction with the fin part 3 is the first direction. The first direction d1 is the direction in which the female member 91 reciprocates. In other words, the first direction d1 is the direction in which the male part 2 guides the female part 91 in a reciprocating manner. 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 is a shape that extends horizontally and bulges upward. That is, the center of the arc of the first male part 21 is located downward relative to the first male part 21.

[0055] The direction in which the male front end 23 extends is a second direction d2, which is different from the first direction d1. The second direction d2 is substantially inclined relative to the first direction d1. In this embodiment, since the first direction d1 is an arc, the second direction d2 is inclined relative to the tangential direction with respect to the endpoint of the arc. The second direction d2 is the direction in which the female member 9 is inserted or removed. In other words, the second direction d2 is a direction different from the direction of extension assuming that the first male part 21 extends along the first direction d1 from the end on the side of the second male part 22. In this embodiment, the second direction d2 is a straight line. The second direction d2 is inclined relative to... Figure 2 The left and right directions in (A) are tilted. The second direction d2 is upward as it moves to the right.

[0056] The inward / outward direction d3 indicates the relative positional relationship. Regarding the first male part 21 and the fin part 3, the inward direction is... Figure 2 The downward direction in (A) is substantially consistent. Regarding the first male part 21 and the fin part 3, the outward direction is consistent with... Figure 2The upward direction in (A) is substantially consistent. The inner and outer directions d3 are consistent with the width direction of the strip 31. In the case of male part 2 and fin part 3, "inner" refers to the position of fin part 3, and "outer" refers to the position of male part 2.

[0057] The thickness direction d4 is relative to Figure 2 The direction orthogonal to the paper surface of (A). The thickness direction d4 is also called the face-back direction. The face direction refers to the direction relative to the paper surface. Figure 2 The direction orthogonal to the paper plane of (A) is the direction facing forward. The back direction refers to the direction relative to the front. Figure 2 The direction of (A) orthogonal to the paper is the direction towards the inside.

[0058] Viewed from the thickness direction d4, the male portion 2 has an inner edge and an outer edge. The inner edge is the boundary between the male portion 2 and the fin portion 3. The outer edge is the edge on the opposite side of the inner edge. The line obtained by extending the inner edge 21L1 of the first male portion 21 towards the side of the second male portion 22 is defined as the extended inner line L1. The line obtained by extending the outer edge 21L2 of the first male portion 21 towards the side of the second male portion 22 is defined as the extended outer line L2.

[0059] Both the first male part 21 and the second male part 22 are raised in the dorsal direction relative to the fin part 3.

[0060] The outer surface of the first male part 21 is a cylindrical surface curved into an arc. When the first male part 21 is cut along 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 is opposite to the inner surface of the female part 91. When the female part 91 reciprocates in the first direction d1, the outer surface of the first male part 21 and the inner surface of the female part 91 rub against each other.

[0061] Viewed from the thickness direction d4, the second male portion 22 has a different shape from the first male portion 21. The outer edge 22L2 of the second male portion 22 is located on the inner side in a stepped manner relative to the outer edge 21L2 of the first male portion 21 at the junction with the first male portion 21. The junction between the first male portion 21 and the second male portion 22 is a stepped portion 25.

[0062] The width of the second male portion 22 is shorter than the width of the first male portion 21. The outer edge 22L2 of the second male portion 22 is located inside the extended outer line L2. The outer edge 22L2 of the second male portion 22 approaches the extended outer line L2 as it moves away from the first male portion 21. Specifically, the outer edge 24L2 of the relay portion 24 approaches the extended outer line L2 as it moves away from the first male portion 21. The outer edge 23L2 of the male anterior portion 23 first approaches the extended outer line L2 and then moves away from the extended outer line L2 as it moves away from the first male portion 21. The outer edge 23L2 of the male anterior portion 23 has a bent shape.

[0063] The male anterior end portion 23 is located outward relative to the extended inner line L1. The inner edge 23L1 of the male anterior end portion 23 moves outward from the extended inner line L1 as it moves away from the first male portion 21. The inner edge 24L1 of the relay portion 24 is aligned with the extended inner line L1.

[0064] In addition to the male part 2 and the fin part 3, the male component 1 also has a first stop 4 and a second stop 5 defining both ends of the reciprocating region 31a, a plurality of protrusions 6 dividing the reciprocating region 31a into intervals shorter than the reciprocating region 31a, and a posture holding part 7 capable of holding the female component 9 in two postures. The male component 1 is symmetrical on both sides.

[0065] The first stop 4 defines one end of the reciprocating region 31a. The first stop 4 protrudes from the fin portion 3 at one end in the direction of extension of the male portion 2. Specifically, the first stop 4 protrudes from the protrusion 32 in the front and back directions. The first stop 4 is arranged at a distance from the male front end portion 23 on the inner side. A loading and unloading region 31b is formed between the first stop 4 and the male front end portion 23 for the mouth portion 91c to pass through. When the mouth portion 91c passes through the loading and unloading region 31b, the first stop 4 is located on the inner side relative to the mouth portion 91c. The inner side relative to the mouth portion 91c refers to the passage 91a of the female portion 91. When the mouth portion 91c moves in the reciprocating region 31a and collides with the first stop 4, the female member 9 is located at one end of the reciprocating region 31a.

[0066] The second stop 5 defines the other end of the reciprocating area 31a. The second stop 5 extends in the direction of the male portion 2 at the other end ( Figure 2 The left end of (A) protrudes from the outer surface of the male part 2. The second stop 5 is formed at the other end of the first male part 21 and is on the opposite side to the second male part 22.

[0067] The protrusion 6 rises from the reciprocating region 31a of the belt portion 31 in the front and back directions. The spacing between adjacent protrusions 6 is substantially the same as the size of the opening 91c (the size in the through direction of the passage 91a).

[0068] The posture-holding portion 7 protrudes inward from the fin portion 3 relative to the portion along the relay portion 24 in the reciprocating region 31a. Specifically, the posture-holding portion 7 protrudes from the protrusion 32 in both the front and back directions. When the opening 91c collides with the first stop 4, the female member 9 is in a posture along the first direction d1. In this case, the posture-holding portion 7 is located inward relative to the opening 91c and restricts the inward movement of the opening 91c.

[0069] like Figure 2 , 4As shown, the thickness of the male component 1 includes the thickness t1 of the first male part 21, the thickness t2 of the relay part 24, the thickness t3 of the male front end part 23, the thickness t4 of the posture holding part 7, the thickness t5 of the first stop 4, the thickness t6 of the second stop 5, the thickness t7 of the protrusion 6, the thickness t8 of the belt part 31, and the thickness t9 of the protrusion part 32.

[0070] The thicknesses of the male part 2 (t1, t2, t3), the posture holding part 7 (t4), the first stop 4 (t5), the second stop 5 (t6), and the protrusion 6 (t7) are all greater than the thickness of the belt part 31 (t8). t1 to t7 > t8. The thicknesses of the male part 2 (t1, t2, t3), the first stop 4 (t5), and the second stop 5 (t6) are all greater than the thickness of the posture holding part 7 (t4) and the protrusion 6 (t7). t1 to t3, t5, t6 > t4, t7. The thickness of the belt part 31 (t8) is greater than the thickness of the protruding part 32 (t9). t8 > t9. The thicknesses of the first male part 21 (t1) and the male front end part 23 (t3) are greater than the thickness of the relay part 24 (t2). t1 and t3 > t2. The thickness t2 of the relay section 24 increases from the side of the first male section 21 toward the male anterior end section 23. The thickness t1 of the first male section 21 is the same as the thickness t3 of the male anterior end section 23. t1 = t3.

[0071] The male component 1 and the female component 9 are, for example, made of synthetic resin. The female part 91 is elastically deformable, and the opening width of the mouth 91c is widened by the elastic deformation of the mouth 91c, and returns to its original shape by restoring it. The opening width of the mouth 91c is widened by elastic deformation to the same size as the thickness t7 at the protrusion 6 and the thickness t4 at the posture holding part 7, and returns to a size smaller than the thickness t7 at the protrusion 6 and the thickness t4 at the posture holding part 7. When the mouth 91c is not elastically deformable, the mouth 91c collides with the protrusion 6 or the posture holding part 7 and is restricted from movement, and cannot pass through the protrusion 6 or the posture holding part 7. When the mouth 91c is elastically deformed, 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 and the protrusion 6, a force is applied to the male component 1 from the mouth 91c, but the male component 1 has a stiffness sufficient to withstand the force.

[0072] 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 and outward directions d3, and the opening 91c cannot pass through the first stop 4 and the second stop 5 in the first direction d1.

[0073] The method for installing and removing the female component 9 is to insert and remove the female component 9 relative to the male front end 23 in the second direction d2. In detail, the procedure for installing the female component 9 is as follows (1) to (3).

[0074] (1) As Figure 5 As shown, the female member 9 is moved from right to left along the second direction d2, and the male front end 23 is inserted into the female part 91 from one side of the passage 91a's through direction. In this way, the male front end 23 is housed inside the female main body 91d, and the first stop 4 is positioned inside the opening 91c. Furthermore, the female member 9 is in a position along the second direction d2.

[0075] (2) Figure 6 As shown, if the female component 9 is moved further to the left along the second direction d2, the mouth 91c is guided by the male front end 23 and the first stop 4 in the second direction d2, and the female component 91 collides with the stepped portion 25, stopping the female component 9. When stopped, the posture holding portion 7 is located inside the female component 91 and outside the mouth 91c, restricting the mouth 91c from moving outward. Furthermore, when stopped, the relay portion 24 and the posture holding portion 7 are housed inside the female main body portion 91d near the stepped portion 25, preventing the female component 91 from moving inward. As a result, the female component 9 is maintained in a posture along the second direction d2.

[0076] (3) Figure 7 As shown, if the female member 9 is pulled outward near the step portion 25, the opening 91c elastically deforms, passing over the posture holding portion 7 and returning to its original position. As a result, the female member 9 assumes a posture along the first direction d1. It should be noted that the posture holding portion 7 is located inside the opening 91c, restricting the opening 91c from moving inward. In this case, the opening 91c can move to the left. However, the rightmost protrusion 6 is located to the left of the opening 91c, restricting the opening 91c from moving to the left.

[0077] (4) If the female component 9 is moved further to the left along the first direction d1, the opening 91c will pass over the rightmost protrusion 6 and return to its original position through elastic deformation, as shown in the figure. Figure 8 As shown, it collides with another protrusion 6. As a result, the female member 9 stops in the state of being located at the first male part 21, and the protrusion 6 is adjacent to the left and right ends of the opening 91c (the two ends of the first direction d1). That is to say, the female member 9 is positioned in the first direction d1.

[0078] The steps for disassembling the female component 9 are as follows (5) to (7).

[0079] (5) If the female component 9 is made to move from such a position... Figure 8 As shown, if the first male part 21 moves to the right (towards the second male part 22) along the first direction d1, then the mouth 91c will elastically deform, passing over the rightmost protrusion 6 and returning to its original position. Figure 9As shown, it collides with the first stop 4. In this case, the posture holding part 7 is located inside the opening 91c, restricting the inward movement of the opening 91c.

[0080] (6) If the female member 9 is pressed inward, the opening 91c will pass over the posture holding part 7 and return to its original position through elastic deformation. In this case, if Figure 6 As shown, the female component 9 is positioned along the second direction d2. It should be noted that the posture holding part 7 is located inside the female component 91 and outside the mouth 91c, restricting the mouth 91c from moving outward.

[0081] (7) If the female component 9 is moved further to the right along the second direction d2 (in a way away from the first male part 21), the female part 91 is pulled out from the male front end 23 and the female component 9 is disassembled from the male component 1.

[0082] According to this embodiment, the reciprocating direction of the female member 9 is consistent with the direction in which the first male part 21 extends, i.e., the first direction d1, and the direction in which the female member 9 can be inserted and removed is consistent with the direction in which the male front end 23 extends, i.e., the second direction d2. As a result, the female member 9 can reciprocate and be inserted and removed only in the direction in which the male part 2 extends. Furthermore, since the front end of the male front end 23 is exposed in space, it is possible to determine the situation in which the female part 91 can be inserted and removed from the male front end 23.

[0083] When viewed from the thickness direction d4, the second male part 22 has a different shape than the first male part 21. Therefore, it is easy to understand that the female component 9 can move in the second male part 22 in a direction different from that of the first male part 21. As a result, it is easy to understand the reciprocating operation and loading / unloading operation of the female component 9.

[0084] Since the fin portion 3 has a band portion 31 that extends along the male front end portion 23 in the second direction d2, it is easy to manipulate: the female component 9 can be inserted and removed relative to the male component 1 simply by moving it in the second direction d2. As a result, the female component 9 is easy to operate.

[0085] Since the male front end 23 is located outward relative to the extended inner line L1, it is easy to control: when the female component 9 is pulled out from the state guided by the male part 2 in a reciprocating motion, the female component 9 can be moved outward relative to the extended inner line L1. As a result, the female component 9 is easy to operate.

[0086] Because the outer edge 22L2 of the second male part 22 is located on the inner side in a stepped manner relative to the outer edge 21L2 of the first male part 21 at the junction with the first male part 21, it is easy to grasp the position of the reciprocating operation and loading / unloading operation of the female component 9. As a result, the female component 9 is easy to operate.

[0087] Since the outer edge 22L2 of the second male part 22 approaches the extended outer line L2 as it moves toward the front end of the second male part 22, the male front end 23 can increase in width as it moves toward the front end, compared to the case where, for example, the outer edge 22L2 of the second male part 22 is parallel to the extended outer line L2 on the inner side. This makes it easier to guide the female part 91 in a posture along the second direction d2 using the male front end 23. In addition, since the male front end 23 is located between the extended inner line L1 and the extended outer line L2, the dimension d3 in the inner and outer directions of the male member 1 is shortened.

[0088] Since the inner edge 24L1 of the relay section 24 coincides with the extended inner line L1, the female member 9 can reciprocate within the range of the first male section 21 and the relay section 24. Furthermore, the female member 9 can be inserted and removed within the range of the relay section 24 and the male front end 23. The female member 9 can easily change its posture along the first direction d1 and along the second direction d2 using the relay section 24.

[0089] Since the male component 1 has the first stop 4, if the female component 9 is moved in the first direction d1 and collides with the first stop 4 through reciprocating operation, it cannot move further in the same direction. As a result, it is easy to grasp that the female component 9 can be moved in the second direction d2 to disassemble it, and the reciprocating operation can be easily changed to a disassembly operation.

[0090] Since the female component 9 has a posture-holding part 7, and the posture-holding part 7 holds the female component 9 in a posture along the first direction d1 and a posture along the second direction d2, the posture of the female component 9 is stable depending on whether the mouth 91c is located inside or outside the posture-holding part 7. As a result, the female component 9 can be easily guided in the first direction d1 and the second direction d2.

[0091] If the female member 9 collides with the first stop 4 in the reciprocating region 31a, the posture holding part 7 is located inside the opening 91c, thus restricting the inward movement of the opening 91c. As a result, the female member 9 is stabilized in a posture along the first direction d1.

[0092] 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 opening 91c is located between adjacent protrusions 6, the protrusion 6 is adjacent to both ends of the opening 91c in the first direction d1, so the female member 9 is positioned.

[0093] This invention is not limited to the above-described embodiments. For example, the first direction d1 in the above embodiments is a direction that is curved into an arc, but this invention is not limited to this and can also be a straight direction.

[0094] In the above embodiment, the male component 1 is symmetrical on both the surface and back, but this invention is not limited to this and may also be asymmetrical on both the surface and back. Specifically, the protrusion 6, the first stop 4, and the posture holding part 7 protrude in both the surface and back directions of the fin part 3 in the above embodiment, but this invention is not limited to this and may also protrude only in either the surface or back direction of the fin part 3.

[0095] In the above embodiment, the fin portion 3 is a plate without holes, but this is not the only limitation in the present invention. It can also be a structure in which through holes are formed in the plate. In addition, the inner edge of the fin portion 3 is arc-shaped in the above embodiment, but this is not the only limitation in the present invention. It can also be a convex and concave shape, such as a wave shape, or other shapes.

[0096] In the above embodiment, the male part 2 only has a first male part 21 and a second male part 22, but it is not limited to this in this utility model. In addition to the first male part 21 and the second male part 22, it may also have one or more third male parts with a structure substantially the same as the second male part 22, or a fourth male part with a structure substantially the same as the first male part 21, etc.

[0097] In detail, in the above embodiment, since the male part 2 only has a first male part 21 and a second male part 22, the loading and unloading area in the male part 2 is one, and it is only formed in the portion along the male front end 23 of the second male part 22.

[0098] For example, in the case where the male portion 2 has a third male portion in addition to the first male portion 21 and the second male portion 22, the first example is as follows: the third male portion protrudes from the fin portion 3 at intervals in the reciprocating direction relative to the second male portion 22 on the side opposite to the first male portion 21. The second example is as follows: the third male portion protrudes from the fin portion 3 at intervals in the reciprocating direction relative to the first male portion 21 on the side opposite to the second male portion 22. In this case, there are two loading / unloading areas, formed along the male front end portion 23 of the second male portion 22 and along the male front end portion of the third male portion.

[0099] Furthermore, in the case where the male portion 2 has multiple third male portions in addition to the first male portion 21 and the second male portion 22, the first example is as follows: the first third male portion protrudes from the fin portion 3 at intervals on the side opposite to the first male portion 21 in the reciprocating direction of extension, relative to the second male portion 22; the second and subsequent third male portions protrude from the fin portion 3 at intervals on the side opposite to the first third male portion 22 in the reciprocating direction of extension. Other examples are omitted. In this case, there are multiple loading and unloading areas, formed along the male front end portion 23 of the second male portion 22 and along the male front end portion of each third male portion.

[0100] In addition, if the male part 2 has 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 intervals on the side opposite to the first male part 21 in the extension direction of the reciprocating direction.

[0101] The first stop 4 and the second stop 5 are formed on the male part 2 of the male member 1 in the above embodiment, but this invention is not limited to this. They can also be formed on the fin part 3 of the male member or on the object.
