本発明の目的は、このような課題を解決し、部品点数の削減、および、組立工数の低減が可能なバックルを提供することにある。   An object of the present invention is to provide a buckle capable of solving such a problem and reducing the number of parts and the number of assembly steps.

本発明のバックルは、筒状の雌部材と、この雌部材に差込係合する雄部材とを備え、前記雄部材は、本体部と、係合部材と、弾性部材とを有し、前記本体部は、金属または金属粉を混入させた樹脂材で形成され、かつ、ベルト取付部およびこのベルト取付部から突出された基部を有し、前記基部は、前記係合部材の一部を収容する収容部と、この収容部から前記係合部材を露出させる開口とを有し、前記係合部材は、金属または金属粉を混入させた樹脂材で形成され、かつ、前記基部の前記収容部の内外方向へ移動可能に収容されるとともに、前記雌部材に係合可能な係合部を有し、前記弾性部材は、前記係合部材を前記収容部の外側へ向かって付勢するとともに、前記係合部材の内側への移動を許容するバックルにおいて、前記弾性部材は、前記収容部２５内に収容され、かつ、前記基部の一部に係止する抜止部を有することを特徴とする。   The buckle of the present invention includes a cylindrical female member and a male member that is inserted into and engaged with the female member, and the male member includes a main body portion, an engaging member, and an elastic member, The main body portion is formed of a resin material mixed with metal or metal powder, and has a belt attachment portion and a base portion protruding from the belt attachment portion, and the base portion accommodates a part of the engagement member. And an opening that exposes the engaging member from the receiving portion, and the engaging member is formed of a resin material mixed with metal or metal powder, and the receiving portion of the base portion And has an engaging portion that can be engaged with the female member, and the elastic member urges the engaging member toward the outside of the containing portion. In the buckle that allows the inward movement of the engagement member, the elastic member is The receiving portion is housed in 25, and characterized by having a retaining portion for engaging a portion of the base.

この構成によれば、弾性部材は、基部の一部に係止する抜止部を備えているから、弾性部材を収容部内に収容すると、弾性部材の抜止部が基部の一部に係止される。すると、弾性部材は、係合部材を収容部の外側へ向かって付勢するとともに、係合部材の内側への移動を許容するから、係合部材の内外への移動によって、雄部材を雌部材に対して係合、解除できる。
本発明のバックルによれば、弾性部材を収容部内に収容すれば、弾性部材の抜止部が抜け止めとなって組み込まれるから、従来のバックルに比べ、部品点数を削減でき、従って、組立工数も低減できる。 According to this configuration, since the elastic member includes the retaining portion that is locked to a part of the base portion, when the elastic member is accommodated in the housing portion, the retaining portion of the elastic member is locked to a part of the base portion. . Then, the elastic member urges the engaging member toward the outside of the housing portion and allows the engaging member to move inward, so that the male member is moved into the female member by moving the engaging member in and out. Can be engaged and released.
According to the buckle of the present invention, if the elastic member is housed in the housing portion, the retaining portion of the elastic member is incorporated as a retaining member, so that the number of parts can be reduced compared to the conventional buckle, and therefore the assembly man-hour is also increased. Can be reduced.

本発明のバックルにおいて、前記弾性部材は、前記係合部材が前記収容部の内外方向へ移動するとき、前記係合部材の移動に連動して移動可能に前記係合部材に保持されていることが好ましい。
この構成によれば、弾性部材が係合部材の移動に連動可能に係合部材に保持されているので、係合部材の内方への移動および外方への移動が的確に行える。 In the buckle of the present invention, the elastic member is held by the engagement member so as to be movable in conjunction with the movement of the engagement member when the engagement member moves inward and outward of the housing portion. Is preferred.
According to this configuration, since the elastic member is held by the engagement member so as to be interlocked with the movement of the engagement member, the engagement member can be accurately moved inward and outward.

本発明のバックルにおいて、前記係合部材は、前記弾性部材を保持する保持部を有し、前記弾性部材は、前記係合部材の前記保持部に保持される被保持部と、この被保持部の前記雄部材差込方向端および反差込方向端に設けられた一対の抜止部とを有し、これら一対の抜止部が前記基部の前記収容部内に形成された係止部に係止される、ことが好ましい。
この構成によれば、係合部材には、弾性部材を保持する保持部が設けられ、弾性部材には、係合部材の保持部に保持される被保持部が設けられているから、保持部に被保持部を保持させることによって、弾性部材を係合部材に簡単に保持させることができる。
また、弾性部材の被保持部の両端、つまり、雄部材差込方向端および反差込方向端に抜止部がそれぞれ設けられているから、弾性部材を保持した係合部材を、基部の収容部内に収容すると、弾性部材の一対の抜止部が基部の収容部内に形成された係止部に係止される。つまり、係合部材は、弾性部材を保持した保持部を挟んで、差込方向端および反差込方向端の両端の抜止部により、基部の係止部に係止されるから、係合部材を基部に安定した姿勢で係止させることができるとともに、係合部材が基部から簡単に外れにくい構造にできる。 In the buckle of the present invention, the engagement member includes a holding portion that holds the elastic member, and the elastic member includes a held portion that is held by the holding portion of the engaging member, and the held portion. And a pair of retaining portions provided at the end of the male member insertion direction and the end of the opposite insertion direction, and the pair of retaining portions are locked to a locking portion formed in the housing portion of the base portion. Is preferable.
According to this configuration, since the engaging member is provided with the holding portion that holds the elastic member, and the elastic member is provided with the held portion that is held by the holding portion of the engaging member. By holding the held portion on the elastic member, the elastic member can be easily held by the engaging member.
In addition, since the retaining portions are provided at both ends of the held portion of the elastic member, that is, the male member insertion direction end and the counter insertion direction end, respectively, the engaging member holding the elastic member is placed in the base accommodating portion. When housed, the pair of retaining portions of the elastic member are latched by latching portions formed in the housing portion of the base. That is, the engaging member is locked to the locking portion of the base by the retaining portions at both ends of the insertion direction end and the anti-insertion direction end across the holding portion holding the elastic member. The base can be locked in a stable posture, and the engaging member can be easily detached from the base.

本発明のバックルにおいて、前記一対の抜止部は、前記被保持部から前記係合部材の反収容方向へ向かうに従って互いに離間する方向へ傾斜する傾斜片によって形成されている、ことが好ましい。
この構成によれば、弾性部材を保持した係合部材を、基部の開口から収容部内に収納すると、基部の開口によって、一対の抜止部を形成する傾斜片が互いに接近する方向へ弾性変形されながら収納されていく。やがて、傾斜片が開口を通過すると、傾斜片は弾性復帰し、基部の開口縁に係止され、これにより、係合部材は基部から抜け止めされる。従って、弾性部材を保持した係合部材を、基部の開口から収容部内に収納するだけで、係合部材を基部に組み込むことができるから、組立作業も極めて簡単に行うことができる。 In the buckle according to the aspect of the invention, it is preferable that the pair of retaining portions are formed by inclined pieces that are inclined in directions away from the held portion toward the counter-accommodating direction of the engaging member.
According to this configuration, when the engaging member holding the elastic member is housed in the housing portion from the opening of the base portion, the inclined pieces forming the pair of retaining portions are elastically deformed in a direction approaching each other by the opening of the base portion. It will be stored. Eventually, when the inclined piece passes through the opening, the inclined piece is elastically restored and is locked to the opening edge of the base, whereby the engaging member is prevented from coming off from the base. Therefore, the engaging member can be incorporated into the base simply by housing the engaging member holding the elastic member in the housing from the opening of the base, and therefore the assembling operation can be performed very easily.

本発明のバックルにおいて、前記弾性部材は、前記一対の抜止部の間に弾性変形部を有し、前記基部は、内部に前記収容部を有する上板および下板を有し、これら上板および下板が壁部で連結され、この壁部に前記弾性部材の弾性変形部が当接可能されている、ことが好ましい。
この構成によれば、基部は、上板および下板を有し、これら上板および下板が壁部で連結され、この壁部に弾性部材の弾性変形部が当接されることで、弾性力が付与され、また、この弾性変形部が抜止部の間にあることで、係合部材を内側に移動するときに、係合部材を安定した姿勢で内側へ移動させることができ、さらに、係合部材に作用していた内側への力がなくなると、弾性部材の弾性復帰力によって、係合部材は安定した姿勢で元の位置に復帰される。 In the buckle of the present invention, the elastic member has an elastic deformation portion between the pair of retaining portions, and the base portion has an upper plate and a lower plate having the accommodating portion therein, and the upper plate and It is preferable that the lower plate is connected by a wall portion, and the elastic deformation portion of the elastic member can be brought into contact with the wall portion.
According to this configuration, the base portion has the upper plate and the lower plate, the upper plate and the lower plate are connected by the wall portion, and the elastic deformation portion of the elastic member is brought into contact with the wall portion, thereby elastically Since the force is applied and the elastically deforming portion is between the retaining portions, when the engaging member is moved inward, the engaging member can be moved inward in a stable posture. When the inward force acting on the engagement member disappears, the engagement member is returned to the original position in a stable posture by the elastic return force of the elastic member.

本発明のバックルにおいて、前記弾性部材は、前記弾性変形部が前記壁部に接触しているときに、前記抜止部が前記基部の前記開口の周縁に接触されている、ことが好ましい。
この構成によれば、弾性変形部が壁部に接触しているときに、抜止部が基部の開口の周縁に接触されているから、つまり、係合部材は外側へ付勢された状態で基部の所定位置に位置決めされているから、安定した係合状態を維持することができる。 In the buckle according to the aspect of the invention, it is preferable that the elastic member has the retaining portion in contact with a peripheral edge of the opening of the base portion when the elastic deformation portion is in contact with the wall portion.
According to this configuration, when the elastic deformation portion is in contact with the wall portion, the retaining portion is in contact with the peripheral edge of the opening of the base portion, that is, the base portion is urged outward. Therefore, a stable engagement state can be maintained.

係合部材３０は、基部２１の収容部２５Ａ，２５Ｂの内外方向へ移動可能に収納されるもので、内方へ移動すると、係合部材３０は収容部２５内に入り込み、その状態から外方へ移動すると、開口２７から露出する係合部材３０の割合が多くなる。係合部材３０は、係合部材本体３１と、この係合部材本体３１の内面側に一体にかつ板状に延設された支持片３４と、この支持片３４に一体成形され弾性部材５０を保持する保持部３５とを有する。
係合部材本体３１は、外側面が差込方向へ向かうに従って内側に弧状に湾曲した操作面３２として形成されているとともに、反差込方向端に雌部材Ｂの被係合部７２に係合可能な係合部３３が形成されている。
支持片３４は、係合部材本体３１の内面差込方向端および反差込方向端に係合部材３０の一側面で、収容部２５内へ収容する際の収容方向（開口２７に対面する内面側）に向かって係合部材本体３１の厚みよりも薄い矩形板状に突出形成されている。これは、支持片３４に連続するようにしてもよい。
保持部３５は、各支持片３４に設けられ、差込方向および収容方向に対して直交する方向へ突出する２つの保持軸３６によって形成されている。保持軸３６は、収容部２５Ａ，２５Ｂ内に収容された状態で、基部２１の上板２２または下板２３に向かって延びており、保持軸３６と係合部材本体３１の内面と間隔をあけて形成され、その間隔に後述する弾性部材５０の一部が入り込んで係止される。 (Engagement member 30)
The engaging member 30 is accommodated so as to be movable inward and outward of the accommodating portions 25A and 25B of the base portion 21. When the engaging member 30 moves inward, the engaging member 30 enters the accommodating portion 25, and from that state outward If it moves to, the ratio of the engaging member 30 exposed from the opening 27 will increase. The engagement member 30 includes an engagement member main body 31, a support piece 34 that is integrally formed on the inner surface side of the engagement member main body 31 and extending in a plate shape, and an elastic member 50 that is integrally formed with the support piece 34. And holding part 35 to hold.
The engagement member main body 31 is formed as an operation surface 32 that is curved inwardly in an arc shape as the outer surface thereof goes in the insertion direction, and can be engaged with the engaged portion 72 of the female member B at the end in the opposite insertion direction. An engaging portion 33 is formed.
The support piece 34 is one side surface of the engagement member 30 at the inner surface insertion direction end and the counter-insertion direction end of the engagement member main body 31, and is accommodated in the accommodation direction (the inner surface side facing the opening 27). ) Projecting into a rectangular plate shape thinner than the thickness of the engaging member main body 31. This may be continuous with the support piece 34.
The holding portion 35 is provided on each support piece 34 and is formed by two holding shafts 36 that protrude in a direction orthogonal to the insertion direction and the accommodation direction. The holding shaft 36 extends toward the upper plate 22 or the lower plate 23 of the base portion 21 while being accommodated in the accommodating portions 25A and 25B, and is spaced from the holding shaft 36 and the inner surface of the engaging member main body 31. A part of the elastic member 50 described later enters and is locked in the interval.

（弾性部材５０）
弾性部材５０は、係合部材３０を収容部２５Ａ，２５Ｂの外側へ向かって付勢するとともに、係合部材３０の内側への移動を許容するもので、係合部材３０に保持されるとともに、係合部材３０が基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収容されたとき、基部２１の一部に係止する抜止部５２を有する。
具体的には、係合部材３０の保持部３５に保持される被保持部５１と、この被保持部５１の差込方向端および反差込方向端に設けられた一対の抜止部５２と、一対の抜止部５２の略中間位置において被保持部５１に設けられた弾性変形部５３とを有する。 (Elastic member 50)
The elastic member 50 urges the engaging member 30 toward the outside of the housing portions 25A and 25B and allows the engaging member 30 to move inward. The elastic member 50 is held by the engaging member 30, When the engaging member 30 is accommodated in the accommodating portions 25 </ b> A and 25 </ b> B from the opening 27 of the base portion 21, the retaining member 52 has a retaining portion 52 that is locked to a part of the base portion 21.
Specifically, a held portion 51 held by the holding portion 35 of the engaging member 30, a pair of retaining portions 52 provided at the insertion direction end and the anti-insertion direction end of the held portion 51, and a pair And an elastically deformable portion 53 provided in the held portion 51 at a substantially intermediate position of the retaining portion 52.

被保持部５１は、係合部材本体３１の内面と保持部３５との間に保持される第１被保持片５１Ａと、この第１被保持片５１Ａの両端から内側（係合部材本体３１と反対側）へ向かって湾曲して延長された第２被保持片５１Ｂとを備える。
被保持部５１が保持部３５に保持された状態で、保持軸３６の先端と上板２２または下板２３との間隔は、弾性部材５０の高さよりも狭く、このため、収容部２５内に収容された状態では、弾性部材５０が保持軸３６から外れることはない。 The held portion 51 includes a first held piece 51A that is held between the inner surface of the engaging member main body 31 and the holding portion 35, and inner sides (from the engaging member main body 31 and the first held piece 51A). 2nd to-be-held piece 51B curved and extended toward the other side.
In a state where the held portion 51 is held by the holding portion 35, the distance between the tip of the holding shaft 36 and the upper plate 22 or the lower plate 23 is narrower than the height of the elastic member 50. In the accommodated state, the elastic member 50 does not come off the holding shaft 36.

一対の抜止部５２は、被保持部５１の第２被保持片５１Ｂの先端から係合部材３０側に向けて屈曲して延長され係合部材３０の反収容方向へ向かうに従って互いに離間する方向へ傾斜する傾斜片５２Ａによって構成されている。これらの傾斜片５２Ａは、係合部材３０が基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収容される際、互いに接近する方向へ弾性変形されながら収納部２５Ａ，２５Ｂ内に収納されたのち、弾性復帰してその先端が基部２１の開口２７の周縁に係止される。このため弾性部材５０の差込方向長さは、開口２７のそれよりも長い。傾斜片５２Ａが弾性変形する際は、変形の度合いによっては、第２被保持部５１Ｂも変形する。   The pair of retaining portions 52 are bent and extended from the tip of the second held piece 51B of the held portion 51 toward the engaging member 30 and are separated from each other as the engaging member 30 moves away from the receiving direction. The inclined piece 52A is inclined. The inclined pieces 52A are accommodated in the accommodating portions 25A and 25B while being elastically deformed in a direction approaching each other when the engaging member 30 is accommodated in the accommodating portions 25A and 25B from the opening 27 of the base portion 21. Then, the tip is elastically restored and the tip thereof is locked to the periphery of the opening 27 of the base 21. For this reason, the length of the elastic member 50 in the insertion direction is longer than that of the opening 27. When the inclined piece 52A is elastically deformed, the second held portion 51B is also deformed depending on the degree of deformation.

弾性変形部５３は、被保持部５１の第１被保持片５１Ａの中間位置で２つの保持軸３６の間から内側へ向かうに従って次第に離れる方向へ傾斜した一対の弾性挟持片５３Ａによって構成されている。この一対の弾性挟持片５３Ａの先端は、略球形状に成形されるとともに、基部２１の壁部２６の山形傾斜面にそれぞれ当接されている。
傾斜片５２Ａの先端の位置は、開口２７の係止部２７Ａに係止した状態で、保持軸３６の内側端よりも係合部材本体３１側まで延びており、保持軸３６と弾性部材５０の第１被保持片５１Ａとが、収容部２５内に位置している。ここで、係合部材３０と弾性部材５０との係合を維持するために、弾性部材５０の第１被保持片５１Ａと保持部３５とが係合している面が、開口２７の端縁よりも内側、つまり、収容部２５内に位置することが好ましい。 The elastic deformation portion 53 is constituted by a pair of elastic clamping pieces 53A that are inclined in a direction of gradually separating from the two holding shafts 36 toward the inside at an intermediate position of the first held piece 51A of the held portion 51. . The ends of the pair of elastic clamping pieces 53A are formed in a substantially spherical shape and are in contact with the angled inclined surfaces of the wall portion 26 of the base portion 21, respectively.
The position of the tip of the inclined piece 52 </ b> A extends to the engagement member main body 31 side from the inner end of the holding shaft 36 in a state of being locked to the locking portion 27 </ b> A of the opening 27, and the holding shaft 36 and the elastic member 50. 51 A of 1st to-be-held pieces are located in the accommodating part 25. FIG. Here, in order to maintain the engagement between the engagement member 30 and the elastic member 50, the surface of the elastic member 50 where the first held piece 51 </ b> A and the holding portion 35 are engaged is the edge of the opening 27. It is preferable to be located on the inner side, that is, in the accommodating portion 25.

（雌部材Ｂ）
雌部材Ｂは、金属のダイキャスト成形によって形成され、表壁６１、裏壁６２、両側に表壁６１および裏壁６２を連結する側壁６３を持った扁平四角筒状の筒体６４を有する。なお、ここで用いる金属は、雄部材Ａの本体部１０や係合部材３０を形成した金属と同じであるが、同じ材料でなくてもよい。
筒体６４には、一端に雄部材Ａの係合部材３０が差し込まれる差込口６５が形成され、他端にベルト取付部６６が形成され、内部に差込口６５から他端に向かって雄部材Ａを収納する収納空間６７が形成されている。ベルト取付部６６は、ベルト２の端部２Ｂを挿通させるベルト挿通孔によって形成されている。 (Female member B)
The female member B is formed by metal die-casting, and has a front wall 61, a back wall 62, and a flat rectangular tubular body 64 having side walls 63 connecting the front wall 61 and the back wall 62 on both sides. In addition, although the metal used here is the same as the metal which formed the main-body part 10 and the engagement member 30 of the male member A, it does not need to be the same material.
The cylindrical body 64 is formed with an insertion port 65 into which the engagement member 30 of the male member A is inserted at one end, a belt attachment portion 66 is formed at the other end, and the inside from the insertion port 65 toward the other end. A storage space 67 for storing the male member A is formed. The belt attachment portion 66 is formed by a belt insertion hole through which the end 2B of the belt 2 is inserted.

側壁６３には、雄部材Ａの操作面３２を雌部材Ｂの外部へ露出させる開口部７１が、表壁６１および裏壁６２の内部に向かって矩形に切り欠き形成されている。開口部７１の反差込方向端には、雄部材Ａの係合部３３が係合される被係合部７２が形成されている。   An opening 71 that exposes the operation surface 32 of the male member A to the outside of the female member B is formed in the side wall 63 in a rectangular cut shape toward the inside of the front wall 61 and the back wall 62. An engaged portion 72 with which the engaging portion 33 of the male member A is engaged is formed at the end of the opening portion 71 in the opposite insertion direction.

＜本実施形態の作用・効果＞
雄部材Ａを組み立てるには、まず、図４に示すように、係合部材３０に弾性部材５０を保持させる。これには、係合部材３０の係合部材本体３１と保持部３５との間に弾性部材５０の第１被保持片５１Ａを嵌め込む。すると、弾性部材５０は、係合部材３０の収容方向への移動は係合部材本体３１と保持部３５とによって規制され、また、差込方向の移動は第２被保持片５１Ｂが保持部３５に当接することによって規制される。これにより、弾性部材５０は、係合部材３０に対して移動を規制された状態で保持される。 <Operation and effect of this embodiment>
To assemble the male member A, first, as shown in FIG. 4, the elastic member 50 is held by the engaging member 30. For this, the first held piece 51 </ b> A of the elastic member 50 is fitted between the engaging member main body 31 of the engaging member 30 and the holding portion 35. Then, in the elastic member 50, the movement of the engagement member 30 in the accommodation direction is restricted by the engagement member main body 31 and the holding portion 35, and the movement in the insertion direction is performed by the second held piece 51B. It is regulated by abutting on. Thereby, the elastic member 50 is held in a state in which the movement is restricted with respect to the engagement member 30.

従って、係合部材３０には、弾性部材５０を保持する保持部３５が設けられ、弾性部材５０には、係合部材３０の保持部３５に保持される被保持部５１が設けられているから、保持部３５に被保持部５１を保持させることによって、弾性部材５０を係合部材３０に簡単に保持させることができる。
ここで、弾性部材５０に対して、係合部材３０の支持片３４が下側になるもの（図４の右側）と、上側になるもの（図４の左側）とを用意しておく。このようにすることで、左右で勝手違いの部材を準備する必要がなく、組立の間違いも発生しにくい。 Therefore, the engaging member 30 is provided with a holding portion 35 that holds the elastic member 50, and the elastic member 50 is provided with a held portion 51 that is held by the holding portion 35 of the engaging member 30. By holding the held portion 51 by the holding portion 35, the elastic member 50 can be easily held by the engaging member 30.
Here, the elastic member 50 is prepared such that the support piece 34 of the engaging member 30 is on the lower side (right side in FIG. 4) and the upper side (left side in FIG. 4). By doing so, it is not necessary to prepare right and left members that are not right and left, and it is difficult for assembly errors to occur.

このようにして弾性部材５０を保持した係合部材３０を、図５に示すように、基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収容する。
係合部材３０が基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収容されていくと、基部２１の開口２７によって、弾性部材５０の一対の抜止部５２を形成する傾斜片５２Ａが互いに接近する方向へ弾性変形されながら収容されていく。やがて、傾斜片５２Ａが開口２７を通過すると、図６に示すように、傾斜片５２Ａは弾性復帰し、基部２１の開口２７の周縁に設けられた係止部２７Ａに係止される。開口２７の周縁において、係止部２７Ａは、開口２７における差込方向の長さより、長い空間をもっており、そこに弾性部材５０の傾斜片５２Ａの先端が当接して係合する。 Thus, the engaging member 30 holding the elastic member 50 is accommodated in the accommodating portions 25A and 25B from the opening 27 of the base portion 21, as shown in FIG.
When the engaging member 30 is accommodated in the accommodating portions 25A and 25B from the opening 27 of the base portion 21, the inclined pieces 52A forming the pair of retaining portions 52 of the elastic member 50 approach each other by the opening 27 of the base portion 21. It is housed while being elastically deformed in the direction. Eventually, when the inclined piece 52A passes through the opening 27, the inclined piece 52A is elastically restored and is engaged with an engaging portion 27A provided on the periphery of the opening 27 of the base portion 21, as shown in FIG. At the periphery of the opening 27, the locking portion 27A has a space longer than the length of the opening 27 in the insertion direction, and the tip of the inclined piece 52A of the elastic member 50 contacts and engages there.

このとき、弾性部材５０の弾性変形部５３である一対の弾性挟持片５３Ａが既に基部２１の壁部２６の山形斜面を挟んだ状態で当接されているから、この一対の弾性挟持片５３Ａによって弾性部材５０には外側への弾性力が付与されることが好ましい。従って、この弾性力により、傾斜片５２Ａが基部２１の開口２７の周縁に密着した状態で係止されるから、係合部材３０は基部２１から抜け止めされる。
この状態では、係合部材３０に弾性部材５０が保持され、弾性部材５０の抜止部５２が開口２７の周縁の係止部２７Ａに密着した状態で係止されているから、弾性部材５０の抜止部５２が抜け止めとなって、係合部材３０が基部２１から外れにくい。 At this time, since the pair of elastic clamping pieces 53A, which are the elastic deformation portions 53 of the elastic member 50, are already in contact with the mountain-shaped slope of the wall portion 26 of the base portion 21, the pair of elastic clamping pieces 53A. It is preferable that an elastic force to the outside is applied to the elastic member 50. Accordingly, since the inclined piece 52 </ b> A is locked in close contact with the peripheral edge of the opening 27 of the base portion 21 by this elastic force, the engagement member 30 is prevented from coming off from the base portion 21.
In this state, the elastic member 50 is held by the engaging member 30, and the retaining member 52 of the elastic member 50 is locked in close contact with the locking member 27 </ b> A at the periphery of the opening 27. The portion 52 is prevented from coming off, and the engaging member 30 is unlikely to come off the base portion 21.

しかも、弾性部材５０の被保持部５１の両端、つまり、雄部材Ａの差込方向端および反差込方向端に抜止部５２がそれぞれ設けられているから、弾性部材５０の一対の抜止部５２が基部２１の開口２７縁に係止される。つまり、係合部材３０は、弾性部材５０を保持した保持部３５を挟んで、差込方向端および反差込方向端の両端の抜止部５２により、基部２１の開口２７の周縁に係止されるから、係合部材３０を基部２１に安定した姿勢で係止させることができるとともに、係合部材３０が基部２１から簡単に外れにくい構造にできる。   Moreover, since the retaining portions 52 are provided at both ends of the held portion 51 of the elastic member 50, that is, at the insertion direction end and the opposite insertion direction end of the male member A, the pair of retaining portions 52 of the elastic member 50 are provided. Locked to the edge of the opening 27 of the base 21. That is, the engaging member 30 is locked to the periphery of the opening 27 of the base portion 21 by the retaining portions 52 at both ends of the insertion direction end and the anti-insertion direction end with the holding portion 35 holding the elastic member 50 interposed therebetween. Thus, the engaging member 30 can be locked to the base portion 21 in a stable posture, and the engaging member 30 can be easily detached from the base portion 21.

このため、雄部材Ａの組立にあたっては、弾性部材５０を保持した係合部材３０を、基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収納するだけで、係合部材３０を基部２１に組み込むことができるから、組立作業も極めて簡単に行うことができる。 For this reason, when assembling the male member A, the engaging member 30 holding the elastic member 50 is simply housed in the housing portions 25A and 25B from the opening 27 of the base portion 21, and the engaging member 30 is incorporated into the base portion 21. Therefore, the assembling work can be performed very easily.

なお、図７に示すように、係合部材３０を内側へ移動すると、弾性部材５０の一対の弾性挟持片５３Ａが壁部２６の対称の山形傾斜面に沿って拡張された状態で係合部材３０が移動されるので、係合部材３０が平行に移動し、係合部材３０を安定した姿勢で内側へ移動させることができ、また、係合部材３０に作用していた内側への力がなくなると、弾性部材５０の一対の弾性挟持片５３Ａの弾性復帰力によって、弾性挟持片５３Ａが元の形状に戻ろうとし、山形傾斜面と摺接しながら、係合部材３０が元の位置へ移動されるため、係合部材３０は安定した姿勢で基の位置に復帰される。従って、係合部材３０の移動を安定した姿勢で確実に行うことができる。
係合部材３０が移動する際には、上板２２または下板２３に形成したガイド突条が一対の弾性挟持片５３Ａの間に摺接してガイドされる。 As shown in FIG. 7, when the engagement member 30 is moved inward, the pair of elastic clamping pieces 53 </ b> A of the elastic member 50 is expanded along the symmetrical angled inclined surface of the wall portion 26. Since the engagement member 30 is moved in parallel, the engagement member 30 can be moved inward in a stable posture, and the inward force acting on the engagement member 30 is also increased. When it disappears, due to the elastic return force of the pair of elastic clamping pieces 53A of the elastic member 50, the elastic clamping pieces 53A try to return to the original shape, and the engaging member 30 moves to the original position while slidingly contacting the angled inclined surface. Therefore, the engaging member 30 is returned to the original position in a stable posture. Therefore, the engagement member 30 can be reliably moved in a stable posture.
When the engagement member 30 moves, the guide protrusion formed on the upper plate 22 or the lower plate 23 is guided by sliding between the pair of elastic clamping pieces 53A.

このようにして組み立てられた雄部材Ａを雌部材Ｂに係合させるには、雄部材Ａの基部２１および係合部材３０を雌部材Ｂの差込口６５から収納空間６７に差し込む。すると、係合部材３０が収納空間６７内に差し込まれていくと、係合部材３０は雌部材Ｂの側壁６３によって内側へ弾性変形されながら差し込まれる。やがて、係合部材３０の係合部３３が雌部材Ｂの側壁６３を越えた位置まで差し込まれると、係合部材３０は外側へ弾性復帰する。すると、係合部材３０の係合部３３が雌部材Ｂの被係合部７２に係合される。つまり、雄部材Ａが雌部材Ｂに係合される。図５において、係合した状態の雌部材Ｂを仮想線で示す。   In order to engage the male member A thus assembled with the female member B, the base 21 and the engaging member 30 of the male member A are inserted into the storage space 67 from the insertion port 65 of the female member B. Then, as the engaging member 30 is inserted into the storage space 67, the engaging member 30 is inserted while being elastically deformed inward by the side wall 63 of the female member B. Eventually, when the engaging portion 33 of the engaging member 30 is inserted to a position beyond the side wall 63 of the female member B, the engaging member 30 elastically returns to the outside. Then, the engaging portion 33 of the engaging member 30 is engaged with the engaged portion 72 of the female member B. That is, the male member A is engaged with the female member B. In FIG. 5, the female member B in an engaged state is indicated by a virtual line.

なお、雄部材Ａと雌部材Ｂとの係合を解除するには、雌部材Ｂの開口部７１から露出されている雄部材Ａの操作面３２を内側へ押圧する。すると、係合部材３０の係合部３３が雌部材Ｂの被係合部７２から外れるので、この状態で雄部材Ａを雌部材Ｂから引き抜くと、両者の係合を解除することができる。 In addition, in order to cancel | release engagement with the male member A and the female member B, the operation surface 32 of the male member A exposed from the opening part 71 of the female member B is pressed inside. Then, since the engaging portion 33 of the engaging member 30 is disengaged from the engaged portion 72 of the female member B, when the male member A is pulled out from the female member B in this state, the engagement between both can be released.

このような構造のバックルでは、雄部材Ａが、本体部１０と、一対の係合部材３０と、一対の弾性部材５０とから構成されているから、従来のバックルに比べ、部品点数を低減できる。つまり、従来のバックルに比べても、蓋部材や止めねじなどが不要であるから、部品点数を削減できる。そのため、弾性部材５０を保持した係合部材３０を、基部２１の開口２７から収容部２５Ａ，２５Ｂ内に収納するだけで、雄部材Ａを組み立てることができるから、組立工数の低減も図れる。
もとより、雌部材Ｂと、雄部材Ａのうち本体部１０および一対の係合部材３０は、金属で形成されているから、金属製のバックルとして形成できる。従って、重量感のある印象を与えることができるバックルを提供できる。 In the buckle having such a structure, since the male member A is composed of the main body portion 10, the pair of engaging members 30, and the pair of elastic members 50, the number of parts can be reduced as compared with the conventional buckle. . In other words, the number of parts can be reduced because a lid member, a set screw, and the like are unnecessary compared to the conventional buckle. Therefore, since the male member A can be assembled only by housing the engaging member 30 holding the elastic member 50 in the housing portions 25A and 25B from the opening 27 of the base portion 21, the number of assembling steps can be reduced.
Of course, since the main body 10 and the pair of engaging members 30 of the female member B and the male member A are formed of metal, they can be formed as a metal buckle. Therefore, the buckle which can give the impression with a heavy feeling can be provided.

＜変形例＞
なお、本発明は、上記実施形態で説明した構造のバックルに限定されるものでなく、次のような変形例も含む。
例えば、図８、図９および図１０に示す構造のバックルであってもよい。これらの図に示すバックルは、上記実施形態に対して、弾性部材５０、係合部材３０、基部２１および雌部材Ｂがそれぞれ異なる。なお、前記実施形態と同様な構成要素については、同一符号を付し、その説明を省略する。
弾性部材５０については、被保持部５１および抜止部５２は前記実施形態と同じであるが、弾性変形部５３の形状が異なる。この弾性変形部５３は、被保持部５１の一端（差込方向端）から反差込方向へ向かって第１被保持部５１Ａと略平行に延長され、第１被保持部５１Ａの略中間点位置から反差込方向へ向かうに従って内側へ湾曲された湾曲片５３Ｂと、この湾曲片５３Ｂの先端から差込方向へ向かって第１被保持片５１Ａと略平行に延長された台座片５３Ｃとを有する形状に形成されている。台座片５３Ｃは、第１被保持片５１Ａの中間位置を跨ぐ長さを有し、その両端が円弧面に形成されている。 <Modification>
In addition, this invention is not limited to the buckle of the structure demonstrated by the said embodiment, The following modifications are also included.
For example, the buckle having the structure shown in FIGS. 8, 9 and 10 may be used. The buckle shown in these drawings differs from the above embodiment in the elastic member 50, the engaging member 30, the base 21 and the female member B. In addition, about the component similar to the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
Regarding the elastic member 50, the held portion 51 and the retaining portion 52 are the same as in the above embodiment, but the shape of the elastic deformation portion 53 is different. The elastically deformable portion 53 extends from one end (end in the insertion direction) of the held portion 51 in the counter-insertion direction so as to be substantially parallel to the first held portion 51A, and is substantially at the midpoint position of the first held portion 51A. A shape having a curved piece 53B that is curved inwardly toward the opposite insertion direction and a pedestal piece 53C that extends substantially in parallel with the first held piece 51A from the distal end of the curved piece 53B toward the insertion direction. Is formed. The pedestal piece 53C has a length straddling the intermediate position of the first held piece 51A, and both ends thereof are formed on arcuate surfaces.

基部２１は、２本の壁部２６の間にスリット２９を有する形状に形成されている。つまり、上板２２、下板２３および端面板２４が幅方向略中間で分割されている。また、壁部２６は、連結杆１４から端面板２４に向かう直線状に形成され、これに弾性変形部５３の台座片５３Ｃの両端が当接されている。
雌部材Ｂには、収納空間６７内に仕切壁６８が差込口６５からベルト取付部６６の近傍にかけて一体成形されている。仕切壁６８は、雌部材Ｂの表壁６１および裏壁６２を連結している構造であるため、これらを補強できるとともに、雄部材Ａのガイドとしての機能も併せ持つ。つまり、雄部材Ａが雌部材Ｂに差し込まれると、雄部材Ａのスリット２９が仕切壁６８をガイドとして差し込まれるため、雄部材Ａが傾いた姿勢で差し込まれるのを防ぐことができる。
また、係合部材３０の支持片３４は、差込方向端および反差込方向端に形成され、その間の溝部が、基部２１に設けられたガイド突条２８と摺接可能で、これにガイドされる。 The base 21 is formed in a shape having a slit 29 between the two wall portions 26.
