[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. 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 to separate from each other. At this time, the engaging piece and the engaged portion are securely engaged with each other. When releasing this engagement, the operating member is pressed from both sides in the direction of approaching each other against the urging force of the coil spring, so that the engaged portion and the engaging piece are disengaged, and the male member is disengaged. Since the member can be pulled out, the male member and the female member of the buckle are completely separated by pulling out the male member from the female member.

Further, as disclosed in Japanese Utility Model Laid-Open No. 61-202212, a leg portion, which is an engaging piece integrally provided on a male member, is elastically deformable and is provided on a female member. Further, the above-mentioned leg portion is provided so as to be engageable with the fixed locking portion, and when the engagement is released, the tip of the leg portion is pressed by the pressing portion to release the engagement with the locking portion and There is one that separates from the female member.

[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 only on the operating member in the direction parallel to the moving direction, and the biasing force does not act in the direction orthogonal thereto. Therefore, there is a problem that rattling occurs between the male member and the female member after engagement due to dimensional play between the engaging piece and the engaged portion. Further, it is impossible to eliminate the above-mentioned play which is the cause of this rattling, and this play is indispensable also for facilitating and ensuring the connecting operation between the male member and the female member. Further, when the male member is released from the female member, the male member has to be pulled out from the female member while pressing the operating member, which causes a problem that both hands are required for the operation.

Further, in the latter case of the above-mentioned conventional technique, the leg portion integrally provided with the male member functions as an elastic member, and the leg portion becomes large in order to obtain a certain amount of elastic force. As a result, the male member becomes large, and further, the length of the buckle in the longitudinal direction becomes long, and the size of the buckle itself becomes large. Furthermore, the leg portion is not elastically engaged with the locking portion, and rattling after the male member and the female member are engaged is inevitable. Further, when releasing the engagement, if the pressing portion is pressed from both sides, a force in the protruding direction due to the elastic force acts on the tip end portion of the leg portion, but the tip end portion of the leg portion does not move in the direction in which the elastic force acts. Since it slides while pressing against the locking part provided at a right angle, in order to completely remove the male member from the female member, it is necessary to use both hands to push the pressing member while pulling out the male member. It was

The present invention has been made in view of the above conventional technique, and there is no rattling between the male member and the female member after mounting, and the engagement between the male member and the female member can be released with one hand. The purpose is to provide an easily feasible bag.

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 attached state.

Each operation member 16 is formed with a long hole 22 extending in a direction orthogonal to the projecting direction of the engaged portion 18, and the long hole 22 projects from the main body portion 12 a of the female member 12 and slides. A guide projection 24, which serves as a guide in the moving direction and serves as a stopper for restricting the sliding range, is inserted. Each operating member 16 is provided so as to be slidable in opposite directions between the both ends of the elongated hole 22 and the positions where the both ends of the guide protrusion 24 abut.

Inside the female member 12, an Ω-shaped elastic member 26 is attached while being sandwiched between the operating members 16. 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 ends 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 pressed by the operating member 16 from both sides and elastically deformed in the attached state of FIG. 1, and the both end surfaces 26a of the elastic member 26 are expanded by the inclined surfaces 38 of the biasing direction changing portion 36. It is elastically deformed in the direction, thereby exerting an urging force on 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.

At this time, the elastic member 26 is elastically deformed, and the tip portion 26a thereof slightly moves to the base end side of the biasing direction changing portion 36 while pressing the both slopes 38 of the biasing direction changing portion 36 against each other. 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 force exerted by the tip end portion 26a of the elastic member 26 on both the inclined surfaces 38 of the urging direction changing portion 36 becomes the maximum. The force acting on the inclined surface 38 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 as the engagement is released. When the male member 10 is projected, the elastic force of the biasing member 26 acts on the male member 10 via the both inclined surfaces 38 until the both end portions 26a of the elastic member 26 do not come into pressure contact with the both inclined surfaces 38.

According to the buckle of this embodiment, when the male member 10 is mounted on the female member 12, the male member 10 is always maintained in a state of being biased in the protruding direction. As a result, the urging force is constantly applied to the engaging portion between the engaging piece 14 and the engaged portion 18, and rattling occurs between the male member 10 and the female member 12 due to external vibration or the like. There is no. Further, when the male member 10 is disengaged, the male member 10 projects from the female member 12 only by pressing the operating member 16, and the engagement piece 14 and the engaged portion 18 are reliably engaged. The male member 10 can be easily and surely removed.

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 swingably provided around a rotary shaft 54, and an engaged piece 18 that engages with the engaging piece 14 of the male member 10 is formed on the operating member 56. ing.
