Description of the Invention: [Technical Field of the Invention] The present invention relates to, for example, a buckle in which the ends 1 of belts such as animal collars or purses are detachably coupled to each other. [Prior Art] As a structure in which the ends of the belts of the animal collar or the belt of the leather bag are connected to each other, as disclosed in the following patent documents. It is composed of an insert body attached to one end of the belt, and a joint body attached to the other end of the belt and inserted into the plug-in body to be engaged with each other. On both sides of the insertion body, the one body is formed into a hook-shaped protrusion to buckle the claw. On the other hand, the "linking member system" is supported by a plate having a receiving portion inside and below, and is supported by a pair of engaging portions in the receiving portion with the support shaft as a center, and a fastening claw of the pair of engaging portions. The spring member is biased in a direction close to each other, and the engaging claw of the insertion body is engaged with the buckle claw of the coupling body. 0 Each member constituting the plug-in body and the link body is formed of metal in order to satisfy the necessary strength. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-102516. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] However, the metal buckle of the above-described prior art has sufficient strength, but has a large number of members and a complicated structure. And the overall metal is also making it a considerable weight. Thus, for example, the use of such a buckle for an animal's collar is an excessive burden for the animal to be placed on 140341.doc 201018418. In addition, the shape of the crotch for the bag or other body can be obtained as necessary, but it is not suitable in terms of weight. If there are a large number of components, the cost of purchasing and managing the components is high, and the assembly time is also high, which is inevitably reflected in the high price of the commodity. Accordingly, the present invention has been made in order to solve the problem of the prior art metal buckle. The purpose of the present invention is to provide a buckle having a sufficiently necessary strength, a small number of components, and being inexpensive and lightweight. [Technical means for solving the problem] In order to solve the problem, the buckle of the present invention has the following configuration. A buckle that is inserted into an insertion opening of a male member and inserted into an insertion opening of the female member, and is coupled to the belt body, and the insertion piece of the male member is provided with a pair of buckles. In other words, the parent member is formed of one of the elastic metal wires, and has one pair of arm portions bent and protruded from both ends of the base portion, and the pair of arm portions are integrally formed by bending processing. In the engaging portion, the pair of engaging portions can be loosened by the elastic deformation of the arm portions, and can be disengaged from the engaged portion of the insertion piece. As described above, since the female member of the buckle of the present invention includes the fastening portion and only the elastic metal wire is bent, the constituent members are less expensive and lighter than the former, and the material cost and the production cost are also very high. In the fifth place, the parent member is formed of a metal wire, so that sufficient strength can be exerted. Further, in the above configuration, one of the pair of female members may be intersected with each other at an intermediate portion of the engaging portion. Thereby, the operation of pressing the pair of arms from the outside can be converted into an effect of widening the interval between the buckles 140341.doc 201018418. Further, if the insertion piece of the male member is held from the thick blood donor member u to the cross in the range in which the arm portions intersect each other, the engagement state of the male member is less swayed and stabilized. In the above configuration, the pair of engaging portions of the female member may be opposed to each other by the inner edges of the f-curved portions. The wide space constitutes the insertion opening of the aforementioned parent member. y. The fastening portion can double as the insertion opening' and the engaging member of the male member can be held by the insertion opening of the engaging portion and the member: stable. The female member is housed in a cover body, and the cover body has an insertion opening that can be inserted into the insertion piece of the front and the second insertion piece, and a storage portion that communicates with the insertion opening to house the parent member, and '• The outer side of the hood is released from the operating portion where the buckled portion is engaged with the engaging portion. The gold female member is free from external impacts and the like, and is more preferable in design than the female member only composed of a metal wire. • The (4) mounting portion for connecting to the belt body is provided on the material body, and the base portion of the female member is fitted to the '^ women's part. Moreover, due to the mother structure and the mother, the cover body and the female member are fixed to each other, and the base portion of the easy-to-use member can also constitute a part of the body mounting portion of the cover body, and can be mounted with sufficient strength with respect to the belt body. .

The mounting portion u has a substantially rectangular shape and forms two slits 1Γ, 1Γ for the through belt 2. The slits u are inserted into the end portions of the belts & the first member, as shown by 1, the male member 1G is attached to the belt as a belt, using a belt loop 4 or the like. On the other hand, the insertion piece 12 protrudes from one side of the long side of the substantially rectangular center of the mounting portion u in a direction orthogonal to the long side, and has a hook-shaped engaged portion that protrudes in a right symmetrical shape, m, and the front end shoulder 140341.doc • 6 · 201018418 Arc-shaped, the overall shape of the arrow with a slight arc. Further, in the male member 10 of the present embodiment, as shown in Fig. 2(d), the insertion piece 12 is bent in the thickness direction with respect to the attachment portion. In the case where the buckle 1 is placed on a curved surface such as a collar of the present embodiment, the buckle 1 is easily attached to the curved surface of the head of the animal to be contacted. However, when the buckle 1 is applied to a belt or the like of a leather bag, since the portion to which the buckle is contacted is generally flat, it is not necessary to cause the insertion piece 12 to be warped with respect to the mounting portion. Next, a description will be given of a female member 2 that can be detached from the male member 10. The galvanic member 20 is formed by forming a circular metal rod having a circular cross section and having elasticity, and forming the metal wire f into the shape shown in Fig. 2 (b) and Fig. 3 . The metal wire which is elastic is preferably made of stainless steel. The female member 20 is provided with one pair of arm portions 22a and 22b which are bent and protruded from both ends of the base portion 21. The arm portions 22a projecting in parallel in the same direction are bent in a direction in which they approach each other to form a substantially rectangular annular portion 23 having a long side of the base portion 21, and a belt 2 as a belt body can be inserted therein. Further, the arm portions 22a and 22b have the curved portion 25 which is curved in a gentle curve in a direction away from each other in the middle portion of the engaging portions 24a and 24b which will be described later. And the oblique line portions π which are inclined in the direction in which the curved bends 26 of the shape are inclined again in the direction in which they are spaced apart from each other, and the oblique line portions 27 intersect each other with a three-dimensional gap h therebetween. Further, the three-dimensional gap h is substantially the same as the thickness of the insertion piece 12 of the male member 10, but may be slightly larger. I4034l.doc 201018418 Further, the arms 22a and 22b are elasticated by the metal wires in the curved portions 25, the curved portions 26, the oblique portions 27, and the like as shown by solid lines and broken lines in Fig. 3(a). The mutual spacing can be expanded by elastic deformation. Further, at the front end of the arm portions 22a and 22b, the engaging portions 24a and 2 which are engaged with the engaged portions 12a and 12b of the male member ίο are provided. The engaging portions 24a and 24b are formed by bending the front end portions of the arm portions 22a and 22b (hatched portions 27 and 27) into a square shape and forming them integrally. In addition, the "character" in this case is not only a character like a character, but also a shape having a slightly arc shape such as a U shape or a J shape. More specifically, 'when the direction in which the arms 22a and 22b are spaced apart from each other is the left-right direction, the front end portion of the engaging portion 24a is formed in the shape of the arm portion 22a from the bottom to the upper side. In the opposite direction, the opposite end portion (10) is folded back along the arm portion in the shape of the arm portion from the top to the bottom. Further, the front end surface 22a of the arm portion 223 is opposite to the direction of the oblique portion 27 of the other arm portion, and the front end portion of the arm portion 2 is opposite to the front end portion of the arm portion 2, and the oblique portion 17 of the arm portion 22a of the other side is substantially The direction of direct communication. [The gap h between the engaging portions 24a and 24b, and the oblique line portion y are substantially the same as the three-dimensional gap y. Here, when the direction in which the arms 22a and 22b are spaced apart from each other is defined as the left and right lateral direction, When viewed in the up-and-down direction, the engaging portion "a, ·" has a shape. Therefore, the inner edge of the curved portion corresponding to the engaging portions 24a and 24b is not the right one, but is substantially opposite to each other. The insertion opening 28 into which the male member-like insertion piece 12 is inserted is formed in a space surrounded by the engagement portions 24a and 24b. 140341.doc 201018418 Further, the insertion opening 28 sees the base portion 23 from the insertion port 28 side. In the case of the direction, it is rectangular, and the expansion and contraction caused by the elastic deformation of the arm portions 22a and 22b can be expanded to a normal state (normal) in which the interval is reduced as shown in Fig. 3(c). And the state expanded as shown in Fig. 3 (d). • In addition, as shown in Fig. 3 (b), from the annular portion 23 of the arm portions 22a, 22b to the middle of the engaging portions 24a, 24b, based on And the reason why the insertion piece 12 is bent in the thickness direction with respect to the mounting portion 11 thereof, and the male member is The cover 30 is bent. The cover 30 that houses the female member 20 will be described below.

The strip mounting portion 32 can be inserted into the belt 2 as a belt body. As shown in FIG. 4(b), the belt attachment portion 32 is bent with respect to the cover main body 31 for the same reason as the bending of the male member 10 and the female member 20. The cover main body 3 1 is provided with the belt attachment portion 32. On the opposite side, the rectangular insertion opening 33 is inserted into the insertion piece 12 of the male φ member 10, and the accommodating portion 34 in which the female member 20 can be housed is formed in the internal space communicating with the insertion opening 33. Also in the accommodating portion 34 a portion opening 35 that is opened after being connected to the side of the belt attachment portion 32. - The other side of the cover body 31 is formed with a side opening 36 that is open to the receiving portion 34 and opens. The cantilever-shaped operation portion 38 is swingably provided by a hinge portion 37 that connects the opening edge of the side vent 36 Each of the hinge portions 37 has a recess 37a on the side of the accommodating portion 34 which is an inner space of the cover main body 31, and each of the operation portions 38 has a projection 39 on the side of the accommodating portion 34 which is an inner space of the cover main body 31. Each of the projections 39 can be inserted into the accommodating portion 34 from the side opening 36. Further, an uneven sliding portion 40 is provided on the outer surface of each of the operating portions. Further, in the belt mounting portion 32, along the frame shape The recessed portion 41 is formed in a shape in which the annular portion 23 including the base portion 2 of the female member 20 is fitted. Next, a method of hiding the parent member 20 in the cover 30 will be described. As shown in Fig. 5(a), the female member 20 is housed in the cover 30, and the arm portions 22a and 22b of the female structural member 20 are inserted into the accommodating portion 34 from the rear opening 35 of the cover main body 31. The shape 23 is fitted to the groove portion 41 of the belt attachment portion 32 and completed. The arm portion 22a, 22b is formed by fitting the annular portion 23 including the base portion 21 to the groove portion 41' of the tape mounting portion 32 so that the insertion opening 28 of the female member 20 is positioned corresponding to the insertion opening 33 of the cover 30. Each of the curved portions 26 abuts against the projections 39' of the respective operation portions 38, and the annular portion 23 serves as a core material of the belt attachment portion 32. The other end side of the belt 2 is inserted into the belt mounting portion 32 as shown in the figure! As shown, the female member 20 housed in the cover 30 is attached to the belt 2 as a belt by sewing or the like. Next, a method of connecting and releasing the buckle 1 will be described with reference to Fig. 5 . First, the buckle 1 is to be coupled, and as shown in Fig. 5 (b), the insertion piece 12 of the male member 1 is inserted into the insertion opening 28 of the female member through the insertion opening 33 of the cover 30. When the insertion piece 12 is inserted into the insertion opening 28, since the engaging portions 24a, 24b constituting the insertion opening 28 are formed of a round bar-shaped metal wire having a circular cross section, and inserting 140341.doc -10- 201018418 into the front end of the piece 12 Since the 12c is also formed in an arc shape, the interval (insertion port 28) of the engaging portions 24a and 24b is smoothly expanded and contracted in accordance with the elastic force generated by the elastic force of the arms 22a and 22b. When the insertion piece 12 is further inserted into the insertion opening 28, the engaging portions 24a, 24b will pass over the two ends of the insertion piece 12 which are arc-shaped, and the engaging portions 24a, 24b are spaced apart (the insertion opening 28) due to the arm portion. The elastic force generated by the elasticity of 22a, 22b is reduced. As shown in Fig. 5(c), the engaged portions i2a, 12b of the insertion piece 12 are engaged with each other in the engaged state, and the insertion piece 12 of the male member 10 is inserted. The father of the arm portions 24a to 24b of the female member 20 is in a cross shape from the thickness direction (in the table in FIG. 5(c)), and is in a state in which the mother member 2 is less swayed and stabilized. To release the connection of the buckle 1, as shown in FIG. 5(d), the operation portion 38 of the cover 30 is pressed from the outside, and the interval between the engagement portions 24a and 24b (insertion port 28) is expanded to extract the male member 1 Insert the piece 12. In other words, when the operation portions 38 and 38 of the cover 30 are pressed from the outside, the operation portions 038 are respectively swung by the hinge portion 37, and the projections 39 are intruded into the accommodating portion 34, and the arm portions 22a and 22b are pressed. Each of the curved portions 26. When the bending portions 26 are pressed, since the arm portions 22a and 22b intersect at the intermediate portion, the interval between the engaging portions 24a and 24b (the insertion opening 28) is expanded by the elastic deformation of the arm portions 22a and 22b. When the engagement between the engaged portions 12a and 12b of the insertion piece 12 is released, the insertion piece 12 of the male member 1 is pulled out, and the connection of the buckle 1 is released. The above description is directed to the buckle 1 of the present embodiment. In the present embodiment, the male member 10 formed of one piece of stainless steel sheet and the female member 20 formed by bending a piece of stainless steel 140341.doc •11·201018418 are formed. 'Achieves the effect of maintaining strength comparable to previous metal buckles, and being lightweight and inexpensive to manufacture. Further, the present embodiment describes a buckle applied to an animal collar, but it can be applied to a buckle of a leather bag or a backpack, etc. within the scope of the technical idea of the present invention. Further, in the present embodiment, the female member 20 is housed in the cover member 3, but the effect of the buckle can be sufficiently exhibited even if the cover 30 is omitted. Further, even in the case where the cover 30 is used, the operation portion 38 of the cover 3 of the present embodiment can be omitted, and the arm portions 22 & 2 and 2 can be directly removed from the side opening 38 of the cover 30 In the state of the buckle, the cover may not be in the form of a built-in female member, but instead use a plate or a sheet as a simple partition, so that the female member 20 and the animal's head or purse are not directly contact. Further, the male member 10 of the continuous application type has a hook shape in the buckled portion 12a and 12b of the insertion piece 12, but it is not necessarily a hook as long as it can be engaged with the fastening portion of the female member. shape.
