[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a buckle which is a hooking tool used for belts, pants hangings, bag bands and the like.

[0002]

[Prior art]

 Conventionally, a buckle provided at both ends of a belt has a male member and a female member as disclosed in Japanese Utility Model Laid-Open No. 2-19304, and a pair of engaging pieces is provided on the male member. A direction in which the female member is provided with a pair of operating members having engaged parts, and the pair of operating members of the female member are linearly slidable in the direction of approaching each other, and the pair of operating members are separated from each other by a coil spring. The buckle that is urged to is known. The sliding direction of the operation member is regulated by the guide portion on the inner surface provided on the female member, and one end of the operation member elastically abuts the stopper portion in the protruding direction at a predetermined position. In this buckle, when the male member is inserted into the female member, the engaging piece and the engaged portion are engaged with each other, and the operating member is biased by the coil spring in the direction of separating from each other. At times, the engagement piece and the engaged portion are surely engaged with each other. Further, when releasing this engagement, the operating member is pressed from both sides in the direction of approaching each other against the biasing force of the coil spring, so that the engaged portion and the engaging piece are disengaged from each other. The male member can be pulled out and the male member is pulled out from the female member to completely separate the male member and the female member of the buckle.

Further, as disclosed in Japanese Utility Model Laid-Open No. 2-33641, an engaged portion is formed on a swing-type operation member, and an engaging piece of a male member engages with the engaged portion. In some cases, the operation member is pressed to release the engagement. This operating member is also urged by the elastic member in the engaging direction of the engaged portion, and the stopper portion is a female member so that the operating member stops at a predetermined position in the urging direction. Has been formed.

[0004]

[Problems to be solved by the device]

 In the former case of the above-mentioned conventional technique, the biasing force of the coil spring acts in a direction parallel to the moving direction of the operating member, whereas the stopper portion acts in the biasing direction only at one end of the operating member. As a result, momentum due to the urging force of the elastic member acts on the operating member, increasing the friction of the sliding contact part between the operating member and the guide part, and reducing the unevenness of the sliding contact surface and painting. There was a problem that baldness etc. occurred. In addition, when the operating member is pushed, there is a problem that frictional resistance is large, the operation becomes awkward, and smooth operability cannot be obtained. Further, when the buckle is assembled, the operation member and the elastic member are attached in an unstable state, and the position of the operation member is easily displaced or tilted.

In the latter case of the above-mentioned conventional technique, the operating member that swings is supported only by one end of the operating member in the swinging direction, and there is no guide during the swinging operation. Is unstable. Furthermore, during assembly of the buckle, the operating member and elastic member are unstable until after the elastic member has been attached to the operating member and the cover member has been attached, it is easy to slip during the assembly process. There was a problem.

The present invention has been made in view of the above conventional technique, and a buckle in which the operation member moves smoothly and the operation member and the elastic member can be easily and reliably assembled. The purpose is to provide.

The buckle of this embodiment has a male member 10 made of resin or metal that is attached to one end of a belt (not shown) and a male member 10 that is attached to the other end of the belt or an attachment piece of a bag (not shown). The male member 10 has a female member 12 made of resin or metal to be mated with each other, and a pair of engaging pieces 14 is formed on the male member 10. The female member 12 is composed of a main body portion 12a and a lid portion 12b. Inside the female member 12, a pair of operating members 16 slidably mounted in a direction orthogonal to the inserting direction of the male member 10 are provided. Has been. In each operating member 16, a pair of engaged portions 18 with which the engaging pieces 14 of the male member 10 engage are formed so as to project in a direction opposite to the inserting direction of the male member 10 in the mounted state. .

An elongated hole 22 is formed in the central portion of each operation member 16 as a guide surface that extends in a direction orthogonal to the protruding direction of the engaged portion 18 and restricts the moving direction and moving range of the operating member. Has been done. A projecting portion 24 that projects from the main body portion 12a of the female member 12 and determines the sliding direction and sliding range of the operating member 16 is inserted into the elongated hole 22. Thereby, the operation member 16 is provided so that the side surface of the convex portion 24 is in contact with the inner surface in the longitudinal direction of the elongated hole 22 and is movable only in the longitudinal direction of the elongated hole 22. The pair of operation members 16 are provided slidably in the directions opposite to each other between the positions where both ends of the elongated hole 22 and both ends of the convex portion 24 contact each other.

In the female member 12, an Ω-shaped elastic member 26 is sandwiched between the pair of operating members 16 and elastically abuts on the inner surface of the operating member 16 at the central portion of the elongated hole 22 substantially extending. Has been installed. The elastic member 26 is made of resin or metal, and the central portion 28 is inserted into the mounting portion 30 projecting from the main body portion 12a of the female member 12, and the concave portion 32 of the central portion 28 and the convex portion 34 of the mounting portion 30 are formed. Are fitted and fixed. Both end portions 26a of the elastic member 26 are in contact with both slopes 38 of the triangular biasing direction changing portion 36 projecting in the protruding direction of the engaging piece 14 of the male member 10. The elastic member 26 is mounted by being elastically deformed by being pressed from both sides by the operating member 16 in the mounted state of FIG. 1, and the both end surfaces 26a are spread by the both slopes 38 of the biasing direction changing portion 36. It is elastically deformed to apply a biasing force to the male member 10 in the protruding direction.

The male member 10 and the female member 12 are integrally formed with attachment portions 40 and 42, respectively, into which end portions of the belt and attachment pieces of the bag are inserted and fixed. Further, the body portion 12a of the female member 12 is integrally formed with two pairs of side wall portions 44 and 46 for forming a space portion having a width and a height into which the engaging piece 14 of the male member 10 can be inserted. There is. Each operation member 16 is slidably provided by being sandwiched between the side wall end portions 44a of the pair of side wall portions 44 formed on the main body portion 12a and the guide wall 46a on the inner surface of the side wall portion 46. . Therefore, the operating member 16 is supported at three points of the convex portion 24, the side wall end portion 44a, and the guide wall 46a, and biased biasing force is applied or unnecessary moment is generated in a state where the elastic member 26 is attached. It is assembled so that it will not happen. The portion sandwiched by the pair of side wall portions 44 is an opening portion 50 into which the male member 10 is inserted.

Next, a method of using the buckle of this embodiment will be described below. First, to mount the male member 10 on the female member 12, as shown in FIGS. 1 and 2, the male member 10 is inserted into the opening 50 of the female member 12, and the engaging piece 14 is engaged. Abut on 18 and push in further. As a result, as the male member 10 is pushed in, the engaging piece 14 moves the engaged portion 18 inward, the elastic member 26 elastically deforms, and the operating portions 16 move toward each other. When the male member 10 is pushed to a position where the engaging piece 14 and the engaged portion 18 can engage with each other, the elastic member 26 moves the operating member 16 to the outside to bring the state of FIG. Engagement is made.

Next, when the buckle is disengaged, each operating member 16 is pressed from both sides toward the center of the female member 12, and the operating member 16 is attached to the elastic member 26. It moves against the force, and the engaged portion 18 of the operating member 16 moves away from the engaging piece 14. At this time, the operating member 16 is guided at three places, the convex portion 24, the side wall end portion 44a, and the guide wall 46a, and further, the elastic member 26 is pressed by the side surface of the substantially central portion thereof, so that the operation member 16 is stably operated. It slides smoothly without any load on the contact part. Then, the elastic member 26 is elastically deformed by the pressing operation of the operating member 16, and the tip portions 26a thereof slightly press the both slopes 38 of the biasing direction changing portion 36 while slightly pushing the biasing direction changing portion 36. Move to the base end side. As a result, the amount of deformation of the biasing member 26 increases, and the tip portion 26a of the biasing member 26 exerts a stronger biasing force on the slope 38. Then, when the engagement piece 14 and the engaged portion 18 are disengaged from each other, the tip end portion 26a of the elastic member 26 exerts a maximum force on both slopes 38 of the biasing direction changing portion 36, and this slope 38 The force acting on the male member 10 is converted into the force for projecting the male member 10 by the inclination of the inclined surface 38, and the male member 10 is projected from the female member 12 when the engagement is released. This protrusion amount is up to a position where both tip portions 26a of the elastic member 26 do not come into pressure contact with both slopes 38.

According to the buckle of this embodiment, the operating member 16 is supported at three points of the convex portion 24, the side wall end portion 44a, and the guide wall 46a, and the side surface of the central portion thereof abuts the elastic member 26. Since they are in contact with each other, they can slide stably during pressing operation, and unnecessary load is not applied to a part of the contact part by generating unnecessary moments on the operating members. Part of the paint on the contact surface does not peel off or become uneven. Further, when the operation operation member 16 and the elastic member 26 are assembled, the attachment state is stable, and the assembly can be efficiently and reliably assembled without being detached or tilted during the assembly.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the same members as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. In the buckle of this embodiment, an operating member 56 is mounted on a rotary shaft 54 projecting from the main body portion 12a, is swingably provided around the rotary shaft 54, and is connected to the engaging piece 14 of the male member 10. The engaged piece 18 to be engaged is formed on the operating member 56. Inside the female member 12, an elastic member 60 including a pair of protruding pieces 58 is provided. The protruding piece 58 of the elastic member 60 also functions as a member that changes the biasing direction of the elastic member 60, and the tips thereof are curved in a direction in which they approach each other. 5 6a is in elastic contact. Further, a mounting portion 66 is integrally formed at the central portion of the elastic member 60, the mounting portion 66 projecting in the projecting direction of the projecting piece 58 and having the elongated hole 64 formed at the center. The protrusions 68 and 69 protruding from the main body portion 12a of the female member 12 are inserted into the elongated holes 64 of the mounting portion 66 to control the moving range of the elastic member 60 in the protruding direction of the male member 10. . The tip end surface 70 of the elastic member 60 in the protruding direction is in contact with the contact portion 72 formed between the protruding pieces 14 of the male member 10. Further, a cutout portion 74 is formed in a part of each operation member 56, and a bottom portion 76 of the cutout portion 74 is formed in an arc shape around the rotation shaft 54 and guides each bottom portion 76. A pair of convex portions 78, which are in sliding contact with each other and contact the both side surface portions 74a and 74b of the cutout portion 74 to regulate the rotation range, are in contact with the main body portion 12a of the female member 12.

Next, a method of using the buckle of this embodiment will be described below. First, in order to mount the male member 10 on the female member 12, as shown in FIG. 4, the male member 10 is inserted into the female member 12 and the engaging piece 14 is engaged with the engaged portion, as in the first embodiment. Abut 18 and push in further. As a result, as the male member 10 is pushed in, the engaging piece 14 rotates the engaged portion 18 outward, and the protruding piece 58 of the elastic member 60 is moved through the abutting portion 56a of the operating member 56. They are urged toward each other and elastically deformed. When the male member 10 is pushed to a position where the engaging piece 14 and the engaged portion 18 can engage with each other, the elastic member 60 causes the engaged portion 18 of the operating member 16 to rotate in the opposite direction. Then, the state shown in FIG. 4 is obtained, and the engagement is surely made. Next, when the buckle is disengaged, each operating member 56 is pressed from both sides toward the center of the female member 12, so that the operating member 16 resists the urging force of the elastic member 60. Then, the engaged portion 18 of the operation member 56 is separated from the engaging piece 14. At this time, the projecting pieces 58 of the elastic member 60 are elastically deformed by the contact portions 56a of the operating member 56 in the direction of approaching each other, and the slopes 62 of the projecting pieces 58 are in pressure contact with the contact portions 56a. Then, when the engagement piece 14 and the engaged portion 18 are disengaged from each other, the force applied to both slopes 62 of the protruding piece 58, which is the urging direction changing portion, becomes maximum, and acts on this slope 62. The force exerted on the male member 10 is converted into a force that causes the male member 10 to project, and the male member 10 is caused to project from the female member 12 as the engagement is released. The amount of protrusion of the male member 10 is determined by the length of the elongated hole 64 of the elastic member 60 and the positions of the protrusions 68 and 69, and the amount by which the engagement piece 14 and the engaged portion 18 are reliably released from engagement. If it is good.

According to the buckle of this embodiment, the operation portion 56 provided so as to be swingable is stable with the bottom portion 76 and the convex portion 78 of the cutout portion 74 centering on the rotation shaft 54. While swinging, the swinging range is regulated by the side surface portions 74a and 74b of the cutout portion 74, so that an unreasonable force is not applied to the elastic member 60. Further, when the rotating operation member 56 and the elastic member 60 are assembled, the positioning of the operation member is ensured by the convex portion 78, and even if the elastic member 60 is attached, the operation is not unstable, and the assembling work can be performed quickly. It can be done reliably.

The buckle of the present invention is not limited to the above-described embodiment, but the shapes of the operating member and the elastic member, and the shapes of the engaged portion and the engaging piece can be appropriately set. The male member and elastic member of the first embodiment and the operating member of the second embodiment may be combined, and the operating member of the first embodiment may be applied to the second embodiment. Further, the shapes of the convex portion and the guide surface can be appropriately set, and the side wall portion or the side surface of the member may be used.
