More specifically, it relates to a buckle for connecting and separating one end of one band-shaped member or the two band-shaped members for use. [Prior Art] A buckle used as a means for connecting and separating both ends of one strip-shaped member or two strip-shaped members. The previous buckle has a latch and a socket into which the latch is locked. The latch includes a latch body and a pair of insertion pieces formed on both sides of the latch body in parallel with each other. An insertion guide surface is formed at the front end portion of each insertion piece, and an operation portion and a locked surface are respectively formed on the base end side of the insertion piece by the insertion guide surface. The socket includes a socket body and an insertion opening formed in the socket body to insert a pin. The insertion hole abuts the insertion guide surface of the insertion piece at the entrance side so that the insertion piece elastically deforms toward the insertion direction at a slightly right angle (inside each other) to form the contact portion, and the contact portion is at the rear side of the insertion direction by the contact portion The locking surfaces to be locked form the locking surfaces and the openings that expose the operating portions of the insertion pieces, respectively. In such a configuration, the latch is locked to the socket, and the insertion piece of the latch is inserted into the insertion hole of the socket. Then, in order to make the insertion guide formed at the front end of each insertion piece abut against the abutting part of the socket, each insertion piece is inserted while being elastically deformed toward the inside of each other. That is, when the locked surface of each insert piece crosses the locking surface formed in the socket, each insert piece in the shape of (2) (2) 200405796 is elastically reset toward the outside, so the insert piece is jammed. The stop surface is locked on a stop surface formed on the socket. In this state, the operating portion of the latch is exposed to the outer surface through the opening of the socket. To remove the pin from the socket, push the pin operating portions exposed on the outer surface toward each other from the opening of the socket to elastically deform the insert piece toward the inside. Then, since the locked surface of each insertion piece is detached from the locking surface formed on the socket, in this state, when the plug is pulled out from the socket, the plug is removed from the socket. However, in the previous buckle, the socket opening of the plug operating portion is exposed in the surrounding wall of the socket, and the opening from the side wall to the inside and outside of the front and back walls is particularly large. In particular, the side opening is larger than the inside, and the front and back walls are inclined. Therefore, 'when the plug is removed from the socket, the plug operation part is exposed from the opening of the socket; when pushing toward the inside, the pushing finger must enter the opening above the necessary, and as a result, the insert of the plug is enlarged It is necessary to deform the elasticity more than necessary. As a result, there is a problem that the insertion piece of the pin is damaged (broken) or there is a problem in durability. SUMMARY OF THE INVENTION The main object of the present invention is to provide a buckle that can solve the problems of damage and durability of an insert. The towel buckle of the present invention, a real male component, and a female component inserted into the male component, and a male component, having a male component body, (3) (3) 200405796 pieces of elastically deformable insert pieces, The female member includes a female member body, and an insertion piece formed on the female member body and inserted into the male member. A hole, an insertion hole formed with the locking surface of the insertion piece, and the male member is locked on the locking surface of the female member, and when the locking surface is locked on the locking surface of the insertion piece, The operation portion of the male member is exposed in a buckle of an opening portion on the outer surface, wherein the opening portion is formed in a peripheral wall of the female member main body including the insertion hole, and is cut from the side wall toward the inside of the front and back walls. α, and a protruding portion protruding from a peripheral edge of the opening portion in the opening portion. In such a configuration, the male member is locked to the female member, and the insertion piece of the male member is inserted into the insertion hole of the female member. Then, the locking surface of the insertion piece is locked on the locking surface of the female member, and the male member is inserted and locked on the female member. In this state, that is, the state in which the male member is inserted and locked on the female member, 'to remove the male member from the female member, the operation member of the exposed male member is pushed from the opening of the female member to release the male member and The locked state of the female member. At this time, when the operating portion of the male member is pushed, a protrusion is formed at the opening portion of the female member, which can solve the problems of damage and durability of the insert. That is, "the insertion piece of the male member does not need to be deformed more than necessary", so that the damage of the insertion piece can be reduced, and the durability can be improved. In the present invention, the protruding portion is an opening edge provided on the opposite side of the peripheral edge of the opening portion and (4) (4) 200405796 and the inlet side of the insertion hole, and the protruding portion faces the inlet side of the insertion hole. Outstanding is better. According to such a configuration, the protruding portion and the entrance side of the insertion hole protrude from the opening edge on the opposite side toward the entrance side. In the buckle of the present invention, there are many cases in which the locking surface is provided near the opening edge of the entrance. In this manner, the locking surface arranged on the entrance side of the opening portion is formed in the form of a protruding portion. With this, when the operation part of the male member is pushed by the finger to release the locking state of the male member and the female member, the position of the fingertip is restricted from approaching the locking surface at the protruding part, because the operation part is pressed near the card with the finger belly. The area of the stop surface, so even if the amount of finger pressing is small, the locked state of the male member and the female member can be released. The buckle of the present invention is characterized in that the protruding portion continuously protrudes from the most separated part from the entrance side of the insertion hole in the notch edge of the front and back walls, and the width dimension of the protruding portion is as The formation of the entrance side of the insertion hole becomes smaller. Here, the width direction of the protruding portion means a direction in which the protruding direction of the protruding portion (the insertion direction of the buckle) intersects with each other. The finger protrusion includes a tapered shape or a sharpened shape as it reaches the entrance side. According to such a structure, 'the protruding portion' is formed in a continuous shape from the notch edge of the front and back walls to the side wall ', so that even if a finger abuts on the protruding portion, the finger will not be compressed in one place. In addition, "the shape is continuously thinned so that it can be reinforced", and damage to the protruding portion can be prevented. (5) (5) 200405796 In the present invention, it is preferable that the protruding portion is formed continuously from the notch edge of the front and back walls to form a curved shape connected to the side wall. According to this structure, since the protruding portion has a continuous curved shape from the notch edge of the front and back walls to the side wall, even if the finger abuts on the protruding portion, the finger will not be compressed and concentrated in one place. Furthermore, due to the curved shape, damage to the protruding portion can be prevented. In the present invention, 'the aforementioned male member is locked on the female member and is sad and depressed' ί / ϋ The opening of the aforementioned female member pushes the exposed male member's operating portion to release the locked state between the male member and the female member, and the protrusion The protruding front end of the part may be configured to be more in the insertion hole than the front end of the insertion piece to be locked on the entrance side of the insertion hole. In the present invention, the male member includes a pair of insertion pieces protruding parallel to each other on both sides of the male member body, and the locked surface and the operation portion are respectively provided on the outer sides of the insertion pieces, and the female member, The two side walls of the male component body are provided with the locking surfaces and the openings. According to such a configuration, the male member is provided with a pair of insertion pieces having a locked surface and an operating portion on the outside, and therefore, when the female member is inserted into the female member, the locked surfaces are formed at the front ends of the pair of insertion pieces. The male member can be locked to the female member in a stable state because it is locked on the female member. In addition, when the male member is detached from the female member, the operation members formed on the outside of the pair of insertion pieces may be pushed inward toward each other, so the male member is easily removed from the female member. In the present invention, it is preferable that the aforementioned male member and female member are formed integrally with a synthetic resin, respectively.

The height of the protrusion 28 (L1 in FIG. 3), that is, the distance L 1 from the deepest position of the notch edge 25C of the front and back walls 21B and 21C to the front end of the protrusion 28 in the insertion direction of the male member 10 is set. The finger that pushes the operation portion 17 cannot enter the gap between the insertion guide surface 16 of the insertion piece 15 and the operation portion 17.
此外，雄構件1 〇插入卡止於雌構件20的狀態下， 操作部1 7之最外側面，是連結雌構件本體2 1的側壁2 1 A 由輪廓線定位於內側。 -11 - (9) (9)200405796 這樣的構成中，將雄構件1 0卡止於雌構件20，是將 雄構件1 0之插入片1 5插入到雌構件2 0之插入孔2 3。於 是，因爲形成於插入片1 5前端的插入導面1 6抵接於雌 構件2 0之抵接部2 4，所以插入片1 5對於插入方向一邊 朝略呈垂直方向（內側）彈性變形一邊插進去。亦即， 插入片15的被卡止面18越過雌構件20之卡止面27，則 因爲彈性變形之插入片1 5彈性復位到原來狀態，所以插 入片15的被卡止面18卡止於雌構件20之卡止面27。藉 此，可將雄構件1 〇卡止於雌構件20。 要將雄構件1 0從雌構件2 0卸下，是從雌構件2 0之 開口部2 5將突出的插入片1 5之前端操作部1 7朝內側推 壓。於是，由於雄構件1 〇之插入片1 5在內側彈性變 形，SP，由於被卡止面1 8從卡止面2 7脫落，這種狀態 下，將雄構件1 0從雌構件2 0拔出，則可將雄構件1 〇從 雌構件2 0卸下。 此時，當雄構件1 〇之操作部17朝內側推壓時，如 第4圖所示，推壓的手指碰到突起部2 8，不會侵入開口 部2 5之深處。因此’由於雄構件1 〇之插入片1 5不會必 要以上地彈性變形，所以插入片1 5的損傷或破損很少， 且，亦可提高耐久性。 推壓的手指碰到突起部2 8，不會侵入開口部2 5之深 處在雄構件1 0之操作部1 7及雌構件2 0的開口部2 5之 間無夾住手指之虞。譬如，當雄構件1 0從雌構件2 0卸 下操作時，將推壓插入片1 5的操作部1 7之手指力量瞬In addition, in a state where the male member 10 is inserted into and locked on the female member 20, the outermost side surface of the operation portion 17 is a side wall 2 1 A connecting the female member body 21 to the inside by a contour line. -11-(9) (9) 200405796 In such a configuration, the male member 10 is locked to the female member 20, and the insertion piece 15 of the male member 10 is inserted into the insertion hole 23 of the female member 20. Therefore, since the insertion guide surface 16 formed at the front end of the insertion piece 15 abuts against the abutment portion 24 of the female member 20, the insertion piece 15 is elastically deformed in a direction slightly perpendicular (inside) to the insertion direction. Plug in. That is, when the locked surface 18 of the insertion piece 15 passes the locking surface 27 of the female member 20, the elastically deformed insertion piece 15 is elastically returned to the original state, so the locked surface 18 of the insertion piece 15 is locked at Locking surface 27 of the female member 20. As a result, the male member 10 can be locked to the female member 20. To remove the male member 10 from the female member 20, the front end operation portion 17 of the protruding insertion piece 15 is pushed inward from the opening portion 25 of the female member 20. As a result, the insertion piece 15 of the male member 10 is elastically deformed on the inside, and since the locked surface 18 is detached from the locking surface 27, in this state, the male member 10 is pulled out from the female member 20. Out, the male member 10 can be removed from the female member 20. At this time, when the operating portion 17 of the male member 10 is pushed inward, as shown in Fig. 4, the pushing finger touches the protruding portion 28 and does not penetrate into the depth of the opening portion 25. Therefore, since the insertion piece 15 of the male member 10 does not need to be elastically deformed as described above, the insertion piece 15 has few damages or breakages, and the durability can be improved. The pushed finger touches the protruding portion 28, and does not penetrate into the depth of the opening portion 25. The finger is not caught between the operating portion 17 of the male member 10 and the opening portion 25 of the female member 20. For example, when the male member 10 is detached from the female member 20, the finger force of the operating part 17 pushing the insertion piece 15 is instantaneous.

At this time, even if the insertion piece 15 is elastically reset toward the outside, the pushing finger will not penetrate into the depth of the opening portion 25 by the protruding portion 28, so the operating portion 17 of the male member 10 and the female member 20 There is no risk of pinching fingers between the openings 25. According to this embodiment, the following effects can be expected. (1) The opening 25 formed in the female member 20 is formed in the surrounding wall of the female member body 21 forming the insertion hole 23 from the side wall 21A to the inner and outer walls 2 1 B and 2 1 C. The opening edge 25B is provided with a protruding portion 28 that protrudes from the side wall-side opening. Therefore, when the male member 10 is removed from the female member 20, the operating portion 17 of the male member 10 is pushed, and the pushing finger touches the protrusion. The portion 28 does not penetrate into the depth of the opening portion 25, that is, since the insertion piece 15 of the male member 10 does not need more elastic deformation, the damage of the insertion piece 15 is small and the durability is also improved. improve. (2) Since the protruding part 28 prevents the pushing finger from penetrating into the depth of the opening 25, it is between the operating part 17 of the male member 10 and the opening 25 of the female member 20 No need to pinch your fingers. That is, when the male member i 〇 is detached from the female member 20, the finger force of the operating part 17 pushing the insertion sheet 5 is momentarily pulled out, or when it is lightened, the insertion sheet 15 is intended to be outward. Elastic reset, even if the insertion piece 15 is elastically reset toward the outside, the pushing finger will not penetrate into the depth of the opening 25 through the protruding portion 28, so the operating portion 17 of the male member 10 and the female member 2 There is no risk of pinching fingers between the openings 2 5 of 0. (3) The protruding portion 28 is continuous from the notch edge 2 5 of the front and back walls 21B, -13 of the female member body 21 (11) (11) 200 405 796 2 1 C, and is formed in a curved shape continuous to the side wall 2 1 A Therefore, even if the finger abuts on the protruding portion 28, the finger will not be compressed and concentrated in one place. Furthermore, due to the curved shape, damage to the protruding portions 28 can be prevented. (4) Of the side wall-side opening edges 25 A and 25B constituting the opening portion 25, a locking surface 27 is provided at the side wall-side opening edge 25A near the entrance of the insertion hole 23. The side wall-side opening edge 25B is provided with a protruding portion 28, so the operating portion 17 of the male member 10 is pushed with a finger. When the locked state of the male member 10 and the female member 20 is released, the finger is used to press the approaching operating portion. Since the position of the locking surface of 17 is 27, even if the amount of pushing by the finger is small, the locking state of the male member 10 and the female member 20 can be released. (5) The male member 10 is provided with a pair of insertion pieces 15 having one of the locked surface 18 and the operation portion 17 on the outer side, and therefore is formed on the pair of insertion pieces 1 in the state of being inserted into the female member 20. The locked surfaces 1 of 5 are locked at the locked surfaces 27 of the female member 20 respectively. Therefore, the male member 10 can be locked to the female member 20 in a stable state. In addition, when the male member 10 is removed from the female member 20, the operation members 17 formed on the outside of the pair of insert pieces 15 can be pressed toward each other inward, so that the male member 10 can be easily removed from the female member. 2 0 Remove. (6) The male component 10 and the female component 20 are formed integrally with synthetic resin, respectively, so they can be mass-produced at low cost. (7) The male member 10 and the female member 20 are respectively provided with mounting holes 1 and 22 through which the locking band members are inserted. Therefore, these mounting holes are provided. 14- HO i (12) (12) 200405796 1 and 22 only insert and lock the band-shaped member, and the male member 10 and the female member 20 can simply connect and fix the band-shaped member. Therefore, it can be advantageously used arbitrarily. (8) In a state where the male member 10 is inserted and locked on the female member 20, the outermost side surface of the operation portion 17 is positioned on the inside by a contour line connecting the side walls 2 1 A of the female member body 21, that is, Since the operation portion 17 of the male member 10 does not protrude from the outer surface of the female member body 21, it is possible to prevent a belt or a belt from being hooked. In addition, the present invention is not limited to the buckle having the structure described in the above embodiment, and includes the following modifications. The above-mentioned embodiment is formed in the opening portion 25 of the female member 20, and is formed into a concave curved surface from the side opening edge 2 5 A toward the front and back walls 2 1 B, 2 1 C, but the shape of the opening portion 25 does not It is limited to this, and other shapes are also possible. For example, as shown in FIG. 5, the opening edges 2 5 A, 2 5 B from the side wall toward the front and back walls 2 1 B, 2 1 C are gradually lowered downward (the side with the mounting hole 2 2 of the female member 20) parallel to each other. It can be inclined in a straight line or a rhombus shape. In this case, only the rhombus-shaped opening portion 2 5 is formed, and the side wall side opening edge 2 5 B can form the protruding portion 28. Regarding the locality L 1 of the projection 邰 28, if a finger pressing the operation portion 17 does not enter the height of the gap between the insertion guide surface 16 of the projection portion 28 and the insertion piece 15 and the operation portion 17, but As shown in FIG. 5, it is preferable to appropriately determine the size L2 between the side wall opening edges 25 A and 25B of the opening portion 25. That is, the dimension L2 between the opening edges 2 5 A and 2 5 B on the side wall is the size corresponding to the size of the pushed finger, that is, the finger touches -15- (13) (13) 200405796 (over) the side wall opening. The dimensions of the edges 2 5 A and 2 5 B determine the height of the protrusions 28. In the aforementioned embodiment, the insertion guide surface 16 'is formed at the front end of the insertion sheet 15, but the insertion guide surface 16 may not be at the front end of the insertion sheet 15, and may be at an intermediate position. In the above embodiment, the locking surface 2 7 is formed on the side wall-side opening edge 2 5 A of the opening 25, but the position of the locking surface 27 is not limited to this, and may be provided differently from the opening 25. The location. In the above-mentioned embodiment, the number of insertion pieces 15 is two, but it may be one piece or three or more pieces. For example, FIG. 6 is a buckle which shows the example where the insertion piece 15 is one piece. In the case of this example, the opening 25 formed in the female member 20 is also formed on only one side. Such a structure can also expect the effects of the above-mentioned embodiments (1) (2) (3) (4) (6) (7) (8). The buckle of the above embodiment is a bag or the like, and can also be used for any purpose. In particular, it is suitable for a use that does not fall off even if it has a certain tensile force or more. In the above-mentioned embodiment, the male member 10 and the female member 20 are formed of synthetic resin (injection molding or injection compression molding), but the invention is not limited to this and may be formed of metal or the like.
