Description

開閉体の開閉装置Switchgear for switchgear
 本発明は、例えば、自動車の開口部に開閉可能に取付けられるリッド等の開閉体の開閉装置に関する。 The present invention relates to, for example, an opening and closing device for an opening and closing member such as a lid attached to an opening of an automobile so as to be openable and closable.
 例えば、自動車の燃料給油口は、正面側が開口したボックス状の固定部材に囲まれた状態で配置されており、この固定部材の開口部には、リッドが開閉可能に取付けられている。また、リッドの裏側には、リッドの押し込み動作によって伸縮すると共に回転して、リッドに係脱し、リッドを閉じた状態に保持したり、開口部からリッドを少し持ち上げて開いた状態としたりする、プッシュロッドが配置されていることがある。 For example, a fuel filler of a car is disposed in a state of being surrounded by a box-like fixing member whose front side is open, and a lid is attached to the opening of the fixing member so as to be able to open and close. In addition, the back side of the lid is expanded and contracted by the pushing operation of the lid and rotates to be engaged with the lid to hold the lid closed or lift the lid a little from the opening to make it open. A push rod may be arranged.
 下記特許文献1には、リッド裏側に配置される共に、外周に凹溝及び傾斜溝を有するプッシュロッドと、該プッシュロッドを支持するケースと、ケースに固定され、前記傾斜溝内で摺動する固定ピンと、ケースに収容され、その出力軸に固着される回転ギヤを有するモータと、一端側に、前記出力軸と並列してケースに回転支持される回転軸部を有し、他端側外周に、モータの回転ギヤに歯合する噛合い部を設け、ロッドの軸方向に交差する方向に回転する、略扇形をなした係止部材と、同係止部材を、プッシュロッドの凹溝に係止する方向に付勢するトーションばねとを備えた、リッド開閉装置が記載されている。 In Patent Document 1 below, a push rod disposed on the back side of the lid and having a recessed groove and an inclined groove on the outer periphery, a case supporting the push rod, and a case fixed to the case slide in the inclined groove A motor having a fixed pin and a rotary gear housed in the case and fixed to the output shaft thereof, and at one end side, a rotary shaft portion rotatably supported by the case in parallel with the output shaft, the other end outer periphery The fan-shaped locking member, which rotates in the direction intersecting with the axial direction of the rod, is provided with a meshing portion that meshes with the rotating gear of the motor, and the locking member is inserted into the recessed groove of the push rod. A lid opening and closing device is described which comprises a torsion spring which biases in a locking direction.
 上記リッド開閉装置においては、固定ピンが傾斜溝の基端側に位置する状態では、プッシュロッドがケースの円筒部開口から大きく突出し、また、トーションバばねに付勢された係止部材の摺動面が、ロッド外周面に接触する。この状態でプッシュロッドが押されると、固定ピンが傾斜溝内を移動し先端側に移動すると共に、係止部材がトーションばねの付勢力によって、回転軸部を介して回転しプッシュロッドの凹溝に係止するので、プッシュロッドがケース内に引き込まれた状態でロックされる。この状態において、モータの回転ギヤが回転して、係止部材がトーションバネの付勢力に抗してロッド外周から離れる方向に回転することで、凹溝から係止部材が離れて、ロッドのロック状態が解除される。 In the lid opening / closing device, in the state where the fixing pin is positioned on the base end side of the inclined groove, the push rod protrudes largely from the opening of the cylindrical portion of the case, and the sliding of the locking member biased by the torsion bar spring The surface contacts the rod outer peripheral surface. In this state, when the push rod is pushed, the fixing pin moves in the inclined groove and moves to the tip side, and the locking member is rotated through the rotation shaft by the biasing force of the torsion spring and the concave groove of the push rod The push rod is locked in a state of being pulled into the case. In this state, the rotation gear of the motor rotates, and the locking member rotates in the direction away from the outer periphery of the rod against the biasing force of the torsion spring, whereby the locking member separates from the recessed groove and locks the rod. The state is released.

 上記の特許文献1のリッド開閉装置においては、モータの出力軸と、略扇形の係止部材の回転軸部とが、その軸方向が平行となるように並列して配置されているので、装置全体が大型化する傾向にあった。そのため、ボックス状の固定部材に、開閉装置の設置スペースを大きく確保しなければならないという不都合が生じる。 In the lid opening / closing device of Patent Document 1 described above, the output shaft of the motor and the rotation shaft portion of the substantially fan-shaped locking member are arranged in parallel so that the axial direction is parallel. The whole has tended to grow in size. Therefore, the box-shaped fixing member has a disadvantage that the installation space for the opening and closing device must be large.
 したがって、本発明の目的は、装置全体の小型化を図ることができる、開閉体の開閉装置を提供することにある。 Therefore, an object of the present invention is to provide an opening and closing device for an opening and closing body which can achieve downsizing of the entire device.
 上記目的を達成するため、本発明は、開口部に開閉可能に取付けられる開閉体の開閉装置であって、ロック溝を有すると共に、前記開閉体に押されて伸縮して、同開閉体に係脱するプッシュロッドと、前記ロック溝に係脱して、前記プッシュロッドの軸方向移動を規制するロック部材と、回転動作する駆動軸を有し、前記ロック部材を回転駆動させる駆動部材と、前記プッシュロッドを軸方向に移動可能で且つ回転可能に保持すると共に、前記ロック部材を保持し、更に、前記駆動軸が前記プッシュロッドの軸方向と並列に配置されるように前記駆動部材を保持する、本体部材とを有し、前記ロック部材は、回動部と、この回動部から延出するロックアーム部とを有し、前記回動部の内側に前記駆動軸が配置されており、同駆動軸の回転駆動に連動して前記回動部が回動することで、前記ロックアーム部が前記ロック溝に係脱するように構成されていることを特徴とする。 In order to achieve the above object, the present invention is an opening and closing device of an opening and closing member attached to the opening so as to open and close, having a lock groove and being pushed and expanded by the opening and closing member. A drive member having a push rod for disengaging, a lock member engaged with the lock groove for restricting axial movement of the push rod, and a drive shaft for rotating operation, the push member for rotationally driving the lock member, and the push Axially movably and rotatably holding a rod and holding the lock member, and further holding the drive member such that the drive shaft is disposed parallel to the axial direction of the push rod; The lock member includes a rotation member and a lock arm extending from the rotation member, and the drive shaft is disposed inside the rotation member. Drive shaft rotation The rotating unit and interlocked by rotating, and said locking arm is adapted to disengage the lock groove to.
 本発明によれば、駆動軸が、プッシュロッドの軸方向と並列に配置されるように、駆動部材が本体部材に保持されているので、駆動軸がプッシュロッドの軸方向に交差して配置された場合と比べて、本体部材の、プッシュロッドの軸方向に交差する方向の長さを短くすることができると共に、ロック部材の回動部の内側に、駆動部材の駆動軸が配置されているので、回動部の外側に駆動軸が配置された場合に比べて、省スペース化することができる。その結果、開閉装置全体として小型化を図ることができ、開閉装置の設置スペースを低減することができる。 According to the present invention, since the drive member is held by the main body member such that the drive shaft is disposed in parallel with the axial direction of the push rod, the drive shaft is disposed so as to cross the axial direction of the push rod. The length of the main body member in the direction intersecting with the axial direction of the push rod can be shortened as compared with the case where the drive member is disposed, and the drive shaft of the drive member is disposed inside the pivot portion of the lock member. Therefore, space can be saved as compared with the case where the drive shaft is disposed outside the pivoting portion. As a result, the overall size of the switchgear can be reduced, and the installation space of the switchgear can be reduced.

 また、図2、図3、及び図9に示すように、第2本体部30は、第1本体部20と同様に一方向に長く延びる略長箱状をなし、その長手方向一端側であって、第1本体部20のロッド保持部21に整合する位置に、本体部材15の分割面Fに対して直交する筒状のロッド保持部31が設けられている。また、ロッド保持部31の内側には、図2や図4、図9に示すカム溝形成突部32が形成されている。更に図9に示すように、カム溝形成突部32における、第2本体部30の長手方向他端部の周面には、ロック部材60のロックアーム部63が出没するロックアーム出没溝34が形成されている。一方、第2本体部30の長手方向他端側であって、第1本体部20の駆動部材保持部23に整合する位置に、前記分割面F側が開口した凹状の駆動部材保持部33が形成されている。 Further, as shown in FIGS. 2, 3 and 9, the second main body portion 30 has a substantially elongated box shape extending in one direction like the first main body portion 20, and is one end side in the longitudinal direction thereof. A cylindrical rod holding portion 31 orthogonal to the divided surface F of the main body member 15 is provided at a position aligned with the rod holding portion 21 of the first main body portion 20. Further, inside the rod holding portion 31, a cam groove forming projection 32 shown in FIG. 2, FIG. 4 and FIG. 9 is formed. Further, as shown in FIG. 9, on the peripheral surface of the other end in the longitudinal direction of the second main body portion 30 in the cam groove forming projection 32, there is a lock arm projection groove 34 in which the lock arm portion 63 of the lock member 60 protrudes and retracts. It is formed. On the other hand, at the other end side in the longitudinal direction of the second main body portion 30, the concave drive member holding portion 33 opened at the divided surface F side is formed at a position aligned with the drive member holding portion 23 of the first main body portion 20. It is done.
 また、図3に示すように、第2本体部30の、駆動部材保持部33を画成する外壁部33a(前記分割面Fとは反対側に位置する壁部)の所定箇所には、ロック部材60の回動部61の回動軸部67(図5(a)参照)を回動支持するための、円形のアーム支持孔35が形成されている。更に図2や図9に示すように、第2本体部30の、駆動部材保持部33を画成する下壁部33bには、ロック部材60の係止解除アーム部65を、駆動部材保持部33から挿出させると共に、スライド可能に保持するための、解除アームスライド溝36が形成されている。 Further, as shown in FIG. 3, the second main body portion 30 is locked at a predetermined position on the outer wall portion 33a (the wall portion located on the opposite side to the dividing surface F) which defines the drive member holding portion 33. A circular arm support hole 35 is formed to rotatably support the rotation shaft portion 67 (see FIG. 5A) of the rotation portion 61 of the member 60. Further, as shown in FIGS. 2 and 9, the lower wall portion 33b of the second main body portion 30 defining the drive member holding portion 33, the locking release arm portion 65 of the lock member 60, and the drive member holding portion A release arm slide groove 36 is formed to slide out from 33 and to be slidably held.
 また、ロッド保持部31の底面中央からは、円柱状をなしたバネ支持柱37が突設されている(図9参照)。このバネ支持柱37に外装されたバネ部材57が、ロッド40の内部空間に挿入配置されることで、ロッド40が開閉体5に近接する方向、すなわち、本体部材15の筒状部17の先端開口(ロッド保持部21側の先端開口を意味する。以下の説明においても同様)からのロッド突出量が大きくなるように、ロッド40が付勢されるようになっている。 Further, from the center of the bottom surface of the rod holding portion 31, a cylindrical spring support pillar 37 is provided so as to protrude (see FIG. 9). The spring member 57 externally mounted on the spring support column 37 is inserted into the internal space of the rod 40 so that the rod 40 approaches the opening / closing body 5, that is, the tip of the cylindrical portion 17 of the main body member 15. The rod 40 is biased to increase the rod projecting amount from the opening (meaning the tip opening on the side of the rod holding portion 21; the same applies to the following description).
 そして、前記第1本体部20及び第2本体部30の開口側端部どうしを互いに突き合わせて、図示しないボルトやナット等を介して互いに固着することで、両本体部20,30が一体化されて本体部材15が組み付けられるようになっている。 Then, the open side end portions of the first main body portion 20 and the second main body portion 30 are butted against each other and fixed to each other via a bolt, a nut, etc. (not shown) so that both main body portions 20 and 30 are integrated. The main body member 15 is assembled.
 この際、第1本体部20のロッド保持部21及び第2本体部30のロッド保持部31によって、本体部材15の分割面Fに直交する方向に伸びる筒状部17が形成され(図3及び図9参照)、該筒状部17によりロッド40が軸方向に移動可能で且つ回転可能に保持される。また、第1本体部20の駆動部材保持部23及び第2本体部30の駆動部材保持部33によって、本体部材15内に保持空間が画成されることになり、図6や図9に示すように、この保持空間に、駆動軸51が、ロッド40の軸方向と並列に配置されるように、駆動部材50が保持されるようになっている。なお、図6に示すように、ロッド40の軸方向から見たときに、ロッド40の軸心C1と、駆動軸51の軸心C2とは、本体部材15の長手方向Aに直交する幅方向Bに対して、位置ずれして配置されている。また、この実施形態においては、固定部材3の開口部3aが、車体1に対して斜め上方を向くように固定されている関係上、ロッド40は、その先端側が斜め上向きに配置され、先端と反対側の基端側は、斜め下向きに配置されるようになっている。 At this time, the cylindrical portion 17 extending in the direction orthogonal to the divided surface F of the main body member 15 is formed by the rod holding portion 21 of the first main body portion 20 and the rod holding portion 31 of the second main body portion 30 (FIG. 3 and FIG. The cylindrical portion 17 allows the rod 40 to be axially movable and rotatably held (see FIG. 9). Further, a holding space is defined in the main body member 15 by the driving member holding portion 23 of the first main body portion 20 and the driving member holding portion 33 of the second main body portion 30, as shown in FIG. 6 and FIG. Thus, the drive member 50 is held in the holding space such that the drive shaft 51 is disposed in parallel with the axial direction of the rod 40. As shown in FIG. 6, when viewed from the axial direction of the rod 40, the axial center C1 of the rod 40 and the axial center C2 of the drive shaft 51 are in the width direction orthogonal to the longitudinal direction A of the main body member 15. It is disposed out of position with respect to B. Further, in this embodiment, in view of the fact that the opening 3a of the fixing member 3 is fixed so as to face obliquely upward with respect to the vehicle body 1, the rod 40 is disposed with its tip side obliquely upward, The opposite proximal side is arranged obliquely downward.
 更に、第1本体部20のカム溝形成突部22及び第2本体部30のカム溝形成突部32の間に、ロッド40外周に設けたカム突部49が摺動可能に嵌入する、カム溝55が形成される(図4参照)。このカム溝55は、いわゆるハートカムと同じ原理のカム溝を筒状部17の内周に沿って一周するように形成したものからなっている。すなわち、図4に示すように、このカム溝55は、ロッド40の先端寄りの所定箇所に形成され、カム突部49が嵌合してロッド40を筒状部17の先端開口から突出した状態に保持する第1嵌合溝55aと、該第1嵌合溝55aよりもロッド基端寄りで、かつ、第1嵌合溝55aに対して周方向に位置ずれした位置に形成され、カム突部49が嵌合してロッド40を筒状部17内に引き込んだ状態に保持する第2嵌合溝55bと、両嵌合溝55a,55bどうしを連結するようにロッド40の軸方向に対して傾斜して形成され、カム突部49を一方の嵌合溝から他方の嵌合溝へとガイドする、ガイド溝55cとから構成されている。なお、図4においては、構造を分かりやすく説明するため、第1本体部20について、ロッド保持部21を省略してカム溝形成突部22を実線で記載している。 Furthermore, a cam protrusion 49 provided on the outer periphery of the rod 40 is slidably fitted between the cam groove forming protrusion 22 of the first main body portion 20 and the cam groove forming protrusion 32 of the second main body portion 30. The grooves 55 are formed (see FIG. 4). The cam groove 55 is formed of a cam groove on the same principle as a so-called heart cam so as to make a round along the inner periphery of the cylindrical portion 17. That is, as shown in FIG. 4, the cam groove 55 is formed at a predetermined position near the tip of the rod 40, and the cam projection 49 is fitted to project the rod 40 from the tip opening of the cylindrical portion 17. The first fitting groove 55a is formed at a position closer to the rod proximal end than the first fitting groove 55a, and at a position displaced in the circumferential direction with respect to the first fitting groove 55a. With respect to the axial direction of the rod 40 so as to connect the second fitting groove 55b for holding the rod 40 in a state of being fitted into the cylindrical portion 17 and the fitting groove 55a, 55b. The guide groove 55c is formed to be inclined and guides the cam projection 49 from one fitting groove to the other fitting groove. In FIG. 4, in order to explain the structure in an easy-to-understand manner, the rod holding portion 21 is omitted and the cam groove forming projection 22 is indicated by a solid line in the first main body portion 20.
 上記ロッド40の伸縮及び回転動作について、図4を参照して説明する。なお、図4(a),(d)は、見る方向を90°変えて記載したもので同じ状態を示しており、図4(b),(c)も、見る方向を90°変えて記載したもので同じ状態を示している。 The expansion and contraction and rotation of the rod 40 will be described with reference to FIG. 4 (a) and 4 (d) show the same state in which the viewing direction is changed by 90 °, and the same state is shown in FIGS. 4 (b) and 4 (c). Show the same condition.
 図4(a),(d)に示すように、カム突部49がカム溝55の第1嵌合溝55aに嵌合した状態では、筒状部17の先端開口からロッド40が突出されている。この状態からロッド40がバネ部材57の付勢力に抗して押圧されると、カム突部49が第1嵌合溝55aから外れ、ガイド溝55cによりガイドされて、ロッド40が回転しながら筒状部17内に引き込まれていき、カム突部49が第2嵌合溝55bに嵌合すると、ロッド40が筒状部17の先端開口から引き込まれた状態に保持される(図4(b),(c)参照)。この状態で再びロッド40がバネ部材57の付勢力に抗して押圧されると、カム突部49が第2嵌合溝55bから外れてガイド溝55cにガイドされ、ロッド40が回転しながら筒状部17の先端開口から突出していき、同カム突部49が第1嵌合溝55aに嵌合することで、ロッド40が筒状部17の先端開口から突出した状態に保持される(図4(a),(d)参照)。このように、ロッド40を押すことによって、カム突部49が、カム溝55の、第1嵌合溝55a、ガイド溝55c、第2嵌合溝55b、ガイド溝55c、第1嵌合溝55a、の順番で繰り返すように移動して、ロッド40を筒状部17から突出した状態又は引き込んだ状態に交互に保持される。 As shown in FIGS. 4 (a) and 4 (d), in a state where the cam projection 49 is fitted in the first fitting groove 55a of the cam groove 55, the rod 40 is projected from the tip end opening of the cylindrical portion 17. There is. In this state, when the rod 40 is pressed against the biasing force of the spring member 57, the cam protrusion 49 is disengaged from the first fitting groove 55a, and is guided by the guide groove 55c. When the cam projection 49 is fitted into the second fitting groove 55b, the rod 40 is held in a state of being drawn in from the distal end opening of the cylindrical portion 17 (FIG. 4 (b ) And (c)). In this state, when the rod 40 is pressed again against the biasing force of the spring member 57, the cam projection 49 is separated from the second fitting groove 55b and guided by the guide groove 55c, and the rod 40 is rotated while rotating. The rod 40 is held in a state where it protrudes from the tip end opening of the cylindrical portion 17 by projecting from the tip end opening of the rod-like portion 17 and fitting the cam projection 49 into the first fitting groove 55a (see FIG. 4 (a) and (d)). Thus, by pushing the rod 40, the cam projection 49 is the first fitting groove 55a, the guide groove 55c, the second fitting groove 55b, the guide groove 55c, and the first fitting groove 55a of the cam groove 55. The rod 40 is alternately held so as to protrude from the cylindrical portion 17 or to be drawn in by repeating movement in the order of.
 また、ロッド40は、開閉体5に設けた係合溝8に対して、次のように係脱する。すなわち、図4(a),(d)に示すように、カム突部49がカム溝55の第1嵌合溝55aに嵌合して、ロッド40が筒状部17の先端開口から突出した状態の回転位置のときに、図8(b)に示すように、ロッド40の係合片43の長手方向が、係合溝8の一対の内側壁と平行になって、開口部8aを通過して係合溝8に対して挿脱可能となる。一方、図4(b),(c)に示すように、カム突部49が第2嵌合溝55bに嵌合して、ロッド40が筒状部17の先端開口から引き込まれた状態の回転位置のときに、図8(a)に示すように、ロッド40の係合片43の長手方向が、係合溝8の一対の内側壁と直角になって、溝の奥方8bに入り込み、幅狭の開口部8aに係合して抜けなくなる。すなわち、カム突部49が第1嵌合溝55aに嵌合した状態で、ロッド40の係合片43と開閉体5の係合溝8との係合が解除され、カム突部49が第2嵌合溝55bに嵌合した状態で、ロッド40の係合片43と開閉体5の係合溝8に係合するように構成されている。 Further, the rod 40 engages and disengages with the engagement groove 8 provided in the opening and closing body 5 as follows. That is, as shown in FIGS. 4A and 4D, the cam projection 49 is fitted in the first fitting groove 55a of the cam groove 55, and the rod 40 protrudes from the tip end opening of the cylindrical portion 17. At the rotational position of the state, as shown in FIG. 8B, the longitudinal direction of the engagement piece 43 of the rod 40 is parallel to the pair of inner side walls of the engagement groove 8 and passes through the opening 8a. Thus, the engagement groove 8 can be inserted and removed. On the other hand, as shown in FIGS. 4 (b) and 4 (c), the cam projection 49 is fitted in the second fitting groove 55b, and the rotation of the rod 40 is drawn from the tip opening of the cylindrical portion 17. When in position, as shown in FIG. 8 (a), the longitudinal direction of the engaging piece 43 of the rod 40 is perpendicular to the pair of inner side walls of the engaging groove 8 and enters the groove 8b, It does not come off by engaging with the narrow opening 8a. That is, the engagement between the engagement piece 43 of the rod 40 and the engagement groove 8 of the open / close member 5 is released in a state where the cam projection 49 is fitted in the first fitting groove 55a, and the cam projection 49 It is configured to engage with the engagement piece 43 of the rod 40 and the engagement groove 8 of the opening / closing body 5 in a state of being fitted in the two fitting grooves 55b.
 次に、ロッド40のロック溝45に係脱して、同ロッド40の軸方向移動を規制する、ロック部材60について、図5~9を参照して具体的に説明する。 Next, the lock member 60 which engages with the lock groove 45 of the rod 40 to restrict the axial movement of the rod 40 will be specifically described with reference to FIGS.
 図5(a),(b)に示すように、このロック部材60は、駆動部材50の駆動軸51に保持され(図9参照)、かつ、駆動軸51の回転駆動に連動して回動する回動部61と、この回動部61から延出して、ロッド40のロック溝45に係脱するロックアーム部63と、回動部61から延出して、ロック溝45とロックアーム部63との係止状態を解除可能な係止解除アーム部65(以下、単に「解除アーム部65」ともいう)とを有している。 As shown in FIGS. 5 (a) and 5 (b), the lock member 60 is held by the drive shaft 51 of the drive member 50 (see FIG. 9) and rotates in conjunction with the rotational drive of the drive shaft 51. Rotation portion 61, a lock arm portion 63 extending from the rotation portion 61 and engaged with the lock groove 45 of the rod 40, and a lock groove 45 and a lock arm portion 63 extending from the rotation portion 61. And an unlocking arm portion 65 (hereinafter, also simply referred to as a "releasing arm portion 65") capable of releasing the locked state of the arm.
 この実施形態における回動部61は、その厚さ方向一端面から突設した、円柱状をなした回動軸部67を有している(図5(a)参照)。図3に示すように、この回動軸部67が、本体部材15を構成する第2本体部30のアーム支持孔35に挿入されることで、駆動部材50の駆動軸51による保持と合わせて、ロック部材60が本体部材15に回動可能に支持されるようになっている(図9参照)。 The pivoting portion 61 in this embodiment has a columnar pivot shaft portion 67 protruding from one end surface in the thickness direction (see FIG. 5A). As shown in FIG. 3, the pivot shaft portion 67 is inserted into the arm support hole 35 of the second main body portion 30 constituting the main body member 15 to match the holding of the drive member 50 by the drive shaft 51. The lock member 60 is rotatably supported by the main body member 15 (see FIG. 9).
 また、回動部61の厚さ方向他端面であって、前記回動軸部67に対して同軸となる位置に、駆動部材50の駆動軸51の外周形状に適合する、軸挿入孔69が形成されている(図5(b)参照)。図6を併せて参照して説明すると、この軸挿入孔69は、その内径が駆動軸51の外径に適合すると共に、その内面の一部が平坦面状にカットされて、駆動軸51の平坦面51aに適合する形状をなした、平坦面69aが形成された形状となっている。 Further, at the other end surface in the thickness direction of the pivoting portion 61, a shaft insertion hole 69 conforming to the outer peripheral shape of the drive shaft 51 of the drive member 50 is provided coaxially with the pivot shaft portion 67. It is formed (refer FIG.5 (b)). 6, the inner diameter of the shaft insertion hole 69 conforms to the outer diameter of the drive shaft 51, and a part of the inner surface is cut into a flat surface. The flat surface 69a is formed in a shape adapted to the flat surface 51a.
 そして、軸挿入孔69の平坦面69aと駆動軸51の平坦面51aとを整合した状態で、軸挿入孔69内に駆動軸51を挿入して、軸挿入孔69の内周と駆動軸51の外周とを接着剤等で固定したり、或いは、軸挿入孔69を駆動軸51が圧入される寸法で形成して、軸挿入孔69に駆動軸51が圧入したりすることで、駆動軸51に対してロック部材60の回動部61が固着される(図6参照)。このように、回動部61の軸挿入孔69内に、駆動部材50の駆動軸51が挿入されることで、図6に示すように、回動部61の内側に駆動軸51が配置される。また、駆動軸51の平坦面51aと、軸挿入孔69の平坦面69aとが互いに当接した状態で、軸挿入孔69内に駆動軸51が挿入されることで、軸挿入孔69内で駆動軸51の回転規制された状態で、駆動軸51と回動部61とが一体化されるため、駆動軸51の回転に連動して回動部61も回動するようになっている。なお、回動部の内側に駆動軸が配置される構造については、上記構造に限定するものではない(他の実施形態については後述の実施形態で説明する)。 Then, with the flat surface 69 a of the shaft insertion hole 69 and the flat surface 51 a of the drive shaft 51 aligned, the drive shaft 51 is inserted into the shaft insertion hole 69, and the inner periphery of the shaft insertion hole 69 and the drive shaft 51. The drive shaft 51 is fixed with an adhesive or the like, or the shaft insertion hole 69 is formed to have a dimension to which the drive shaft 51 is press-fitted, and the drive shaft 51 is press-fitted into the shaft insertion hole 69. The rotation portion 61 of the lock member 60 is fixed to the portion 51 (see FIG. 6). In this manner, the drive shaft 51 of the drive member 50 is inserted into the shaft insertion hole 69 of the pivot portion 61, whereby the drive shaft 51 is disposed inside the pivot portion 61 as shown in FIG. Ru. In addition, the drive shaft 51 is inserted into the shaft insertion hole 69 in a state where the flat surface 51 a of the drive shaft 51 and the flat surface 69 a of the shaft insertion hole 69 abut each other. In a state in which the rotation of the drive shaft 51 is restricted, since the drive shaft 51 and the rotation portion 61 are integrated, the rotation portion 61 also rotates in conjunction with the rotation of the drive shaft 51. The structure in which the drive shaft is disposed inside the pivoting part is not limited to the above structure (other embodiments will be described in the embodiments to be described later).
 また、前記解除アーム部65は、回動部61の外周の所定箇所から、所定長さで真直ぐに(直線状に)延出した角柱状をなしている。この係止解除アーム部65は、ロック部材60が本体部材15に保持された状態で、解除アームスライド溝36(図9参照)から挿出されて、ロック溝45とロックアーム部63との係止状態を、解除操作可能となっている。なお、係止解除アーム部としては、使用者が把持できて解除操作が可能であれば、どのような形状でもよい。 Further, the release arm portion 65 has a prismatic shape extending straight (in a straight line) at a predetermined length from a predetermined position on the outer periphery of the rotating portion 61. The lock release arm 65 is inserted from the release arm slide groove 36 (see FIG. 9) in a state where the lock member 60 is held by the main body member 15, and the engagement between the lock groove 45 and the lock arm 63 is made. The stop state can be released. In addition, as a lock release arm part, as long as a user can hold | grip and release operation is possible, what kind of shape may be sufficient.
 また、ロックアーム部63は、駆動部材50の駆動軸51が回転駆動して、その回転駆動に連動して回動部61が回動することで、所定方向に回動してロッド40のロック溝45に係脱するように構成されている。 Further, the lock arm portion 63 rotates in a predetermined direction by the rotation of the rotation portion 61 in conjunction with the rotational drive of the drive shaft 51 of the drive member 50, thereby locking the rod 40. The groove 45 is configured to be disengaged.
 この実施形態における前記ロックアーム部63は、図5~7に示すように、回動部61の外周から、前記解除アーム部65の軸方向に対して、所定角度で斜めに延出した傾斜部71を有している。この傾斜部71の延出方向の先端部71aは、解除アーム部65の軸方向に沿って延びており、この先端部71aから、前記解除アーム部65に対して離れるように、回動部61の軸方向に沿って軸方向延出部73が延出している。更に、この軸方向延出部73の延出方向の先端部73aから、係止部75が延出している。この係止部75は、図6や図7に示すように、ロックアーム部63を軸方向から見たときに、前記傾斜部71に対して「くの字」状をなすように所定角度で屈曲した形状をなしている。この係止部75が、ロッド40のロック溝45に対して係脱して、同ロッド40の軸方向移動を規制する部分となっている。また、ロックアーム部63の、ロッド40のロック溝45に係脱する部分である係止部75は、前記傾斜部71及び解除アーム部65に対して軸方向に位置ずれした位置、具体的には、ロッド40の先端側に位置ずれして配置されている。 The lock arm portion 63 in this embodiment is, as shown in FIGS. 5 to 7, an inclined portion obliquely extending at a predetermined angle with respect to the axial direction of the release arm portion 65 from the outer periphery of the rotating portion 61. It has 71. The distal end portion 71 a in the extension direction of the inclined portion 71 extends along the axial direction of the release arm portion 65, and the pivoting portion 61 is separated from the distal end portion 71 a with respect to the release arm portion 65. An axially extending portion 73 extends along the axial direction of the shaft. Further, the locking portion 75 extends from the distal end portion 73 a in the extension direction of the axially extending portion 73. As shown in FIG. 6 and FIG. 7, when the lock arm 63 is viewed in the axial direction, the locking portion 75 forms a "で" shape with respect to the inclined portion 71 at a predetermined angle. It has a bent shape. The locking portion 75 is engaged with and disengaged from the lock groove 45 of the rod 40 to restrict axial movement of the rod 40. In addition, a locking portion 75 which is a portion of the locking arm portion 63 engaged with or disengaged from the locking groove 45 of the rod 40 is a position axially offset from the inclined portion 71 and the release arm portion 65, specifically Are disposed on the tip end side of the rod 40 in a displaced manner.
 そして、この実施形態におけるロックアーム部63は、上記のような形状を採用することによって、図6や図7に示すように、回動部61の軸方向から見たときに(すなわち、回動軸部67の軸方向から見たときに)、前記傾斜部71と、前記係止部75とによって、「くの字」状をなすように屈曲した屈曲部77を有することとなる。また、図6や図7に示すように、この屈曲部77の頂部77a(屈曲部77を構成する部材が交差して、外方に出っ張る部分を意味する。この実施形態では、回動部61を軸方向から見たときの、傾斜部71と係止部75との交差部分における、外方に出っ張った部分)は、ロックアーム部63の係止部75が、ロッド40のロック溝45に係止する方向に、駆動部材50の駆動軸51によって回動部61が回動する際に、同回動部61の回動方向(図6の矢印M方向)に向くように配置されている。なお、ロックアーム部の屈曲部において、「くの字」状に屈曲したとは、回動部を軸方向から見たときに、所定の部材と、これに対して屈曲する他の部材とのなす角度(ここでは傾斜部71と係止部75とのなす角度)が、180度未満となる形状であることを意味する。 And, as shown in FIG. 6 and FIG. 7, the lock arm portion 63 in this embodiment has a shape as described above, when viewed from the axial direction of the rotation portion 61 (ie, rotation) When viewed from the axial direction of the shaft portion 67), the inclined portion 71 and the locking portion 75 have a bent portion 77 which is bent to form a "く" shape. Further, as shown in Fig. 6 and Fig. 7, the top 77a of this bent portion 77 (means a portion where the members constituting the bent portion 77 intersect and project outward. In this embodiment, the turning portion 61). Of the locking arm 63 in the locking groove 45 of the rod 40 at the intersection of the inclined portion 71 and the locking portion 75 when viewed from the axial direction. When the rotation portion 61 is rotated by the drive shaft 51 of the drive member 50 in the locking direction, the rotation portion 61 is arranged to face in the rotation direction (the arrow M direction in FIG. 6). . In the bent portion of the lock arm portion, being bent in the shape of "く" means that a predetermined member and another member bent with respect to the predetermined member when the turning portion is viewed from the axial direction. This means that the angle formed (here, the angle between the inclined portion 71 and the locking portion 75) is a shape that is less than 180 degrees.
 また、この実施形態においては、回動部61から傾斜部71が延出され、更にこの傾斜部71から、軸方向延出部73や係止部75が延出した構造とされ、回動部61よりも上方部分の重さが重くなっており、かつ、図6に示すように、ロックアーム部63の係止部75が、ロッド40のロック溝45に係止した状態において、ロックアーム部63の係止部75が、ロッド40のロック溝45に近接する方向となるように、屈曲部77の頂部77aが配置されている。その結果、図6に示すように、ロックアーム部63の重心Gが、回動軸部67の軸心C2よりも屈曲部77側に偏心した位置に配置されて、ロックアーム部63に矢印M方向の回動モーメントが作用するため、ロック部材60に外力が作用してない状態においても、係止部75が、ロック溝45から離れずに係止する方向となるように、ロックアーム部63が回動するようになっている。すなわち、この実施形態におけるロック部材60は、図6に示すように、ロックアーム部63の係止部75が、ロッド40のロック溝45に係止した状態において、ロック部材60の自重によって作用する回動方向(矢印M方向)が、同ロックアーム部63の係止部75が前記ロック溝45に係止する方向になるように、駆動部材50の駆動軸51に保持されている。 Further, in this embodiment, the inclined portion 71 is extended from the rotating portion 61, and the axially extending portion 73 and the locking portion 75 are further extended from the inclined portion 71. In the state where the weight of the upper portion is heavier than 61 and the locking portion 75 of the locking arm portion 63 is locked to the locking groove 45 of the rod 40 as shown in FIG. The top 77 a of the bent portion 77 is disposed such that the locking portions 75 of the 63 are in the direction approaching the lock groove 45 of the rod 40. As a result, as shown in FIG. 6, the center of gravity G of the lock arm portion 63 is arranged at a position eccentric to the bent portion 77 side with respect to the axial center C2 of the pivot shaft portion 67. Lock arm 63 so that the locking portion 75 locks without leaving the lock groove 45 even in a state where no external force is applied to the lock member 60, since the rotational moment in the direction acts. Is supposed to rotate. That is, as shown in FIG. 6, the locking member 60 in this embodiment acts by the weight of the locking member 60 in a state where the locking portion 75 of the lock arm portion 63 is locked to the locking groove 45 of the rod 40. It is held by the drive shaft 51 of the drive member 50 so that the rotation direction (arrow M direction) is the direction in which the locking portion 75 of the lock arm portion 63 locks in the lock groove 45.
 なお、ロック部材の形状は、上記形状に限定されるものではない(代表的な他の実施形態については、後述の実施形態で説明する)。また、この実施形態のロック部材60は、ロックアーム部63を構成する、傾斜部71と係止部75とを、軸方向延出部73を介して軸方向に位置ずれした構成となっているが、例えば、軸方向延出部73を介さずに、傾斜部71と係止部75とを同一軸線上に一体形成して、「くの字」状をなす構造としてもよい。更に、ロックアーム部を「くの字」状に屈曲した形状としなくとも、例えば、直線状に形成したり、コ字状や、U字状、L字状等に形成したりしてもよく、少なくとも、回動部と、ロッドのロック溝に係止するロックアーム部とを有する構造であればよい。 In addition, the shape of a locking member is not limited to the said shape (A typical other embodiment is demonstrated by the below-mentioned embodiment). Further, the lock member 60 of this embodiment has a configuration in which the inclined portion 71 and the locking portion 75, which constitute the lock arm portion 63, are displaced in the axial direction via the axially extending portion 73. However, for example, the inclined portion 71 and the locking portion 75 may be integrally formed on the same axis without the axial extension portion 73, and may have a "leg-shaped" structure. Furthermore, the lock arm portion may be formed in a straight line, a U-shape, a U-shape, an L-shape or the like, for example, instead of being bent in a "く" shape. It is sufficient if it has a structure having at least a pivoting portion and a lock arm portion which is locked to the lock groove of the rod.
 次に、上記構造からなる開閉装置10の使用方法及び作用効果について説明する。 Next, a method of use and effects of the opening and closing device 10 having the above structure will be described.
 すなわち、図1に示すように、例えば給油時などにおいて、固定部材3の開口部から開閉体5が開いた状態では、カム突部49がカム溝55の第1嵌合溝55aに嵌合して(図4(a),(d)参照)、筒状部17の先端開口から、ロッド40が突出した状態に保持されている。また、駆動部材50の駆動軸51は、図7(b)や図8(b)に示すように、ロックアーム部63の係止部75が、ロッド40のロック溝45に係止しないように、回動させた位置にある。 That is, as shown in FIG. 1, the cam projection 49 is fitted in the first fitting groove 55 a of the cam groove 55 in a state where the opening / closing body 5 is opened from the opening of the fixing member 3 at the time of refueling, for example. The rod 40 is held in a state where the rod 40 protrudes from the tip end opening of the cylindrical portion 17 (see FIGS. 4A and 4D). Further, as shown in FIGS. 7B and 8B, the drive shaft 51 of the drive member 50 prevents the locking portion 75 of the lock arm portion 63 from locking in the locking groove 45 of the rod 40. , In the pivoted position.
 そして、例えば給油が終了して、上記の状態から開閉体5を閉じていくと、開閉体5の係合部7の係合溝8内に、ロッド40の係合片43が入り込んで(図8(b)参照)、同開閉体5によって、ロッド40がバネ部材57の付勢力に抗して押圧されていく。すると、カム突部49が、カム溝55の第1嵌合溝55aから外れてガイド溝55cにガイドされ、ロッド40が回転しながら筒状部17内に引き込まれていき、図4(b),(c)に示すように、同カム突部49が第2嵌合溝55bに嵌合すると、ロッド40が筒状部17の先端開口から引き込まれた状態に保持される(8(a)参照)。このとき、ロッド40の係合片43が回転して、その長手方向が開閉体5の係合溝8の長手方向と直交する方向となり、係合片43が係合溝8内に係合して、開閉体5が閉じた状態に維持される。 Then, for example, when the opening and closing body 5 is closed from the above state after the fueling is completed, the engaging piece 43 of the rod 40 enters the engaging groove 8 of the engaging portion 7 of the opening and closing body 5 (see FIG. 8 (b)), the rod 40 is pressed against the biasing force of the spring member 57 by the opening / closing body 5. Then, the cam projection 49 is separated from the first fitting groove 55a of the cam groove 55 and guided by the guide groove 55c, and the rod 40 is drawn into the cylindrical portion 17 while being rotated, as shown in FIG. As shown in (c) and (c), when the cam projection 49 is fitted in the second fitting groove 55b, the rod 40 is held in a state of being drawn in from the distal end opening of the cylindrical portion 17 (8 (a) reference). At this time, the engagement piece 43 of the rod 40 is rotated, and the longitudinal direction thereof is perpendicular to the longitudinal direction of the engagement groove 8 of the opening / closing member 5, and the engagement piece 43 is engaged in the engagement groove 8. Thus, the opening / closing body 5 is maintained in the closed state.
 そして、例えば自動車のドライバーが開閉体5のロック操作をすると、それに連動して、駆動部材50が作動し、駆動軸51が所定方向に回転して、ロック部材60の回動部61が矢印M方向(図6参照)に回動し、同回動部61を介してロックアーム部63が、ロッド40のロック溝45に近接する方向に回動し、その係止部75が、第2本体部30のロックアーム出没溝34を通過して、ロック溝45に対して斜め方向から入り込んで同ロック溝45に係止する。その結果、ロッド40の更なる押し込みが規制されるので、固定部材3の開口部に対して開閉体5を閉じた状態にロックすることができる。 Then, for example, when the driver of the automobile locks the opening / closing body 5, the driving member 50 operates in conjunction with it, the driving shaft 51 rotates in a predetermined direction, and the turning portion 61 of the locking member 60 is an arrow M In the direction (see FIG. 6), the lock arm 63 pivots in the direction approaching the lock groove 45 of the rod 40 via the pivot 61, and the locking portion 75 of the second main body After passing through the lock arm recess groove 34 of the portion 30, the lock groove 45 is inserted into the lock groove 45 from an oblique direction and locked in the lock groove 45. As a result, since the further pushing of the rod 40 is restricted, the opening / closing body 5 can be locked in a closed state with respect to the opening of the fixing member 3.
 一方、例えば自動車のドライバーが開閉体5のロック解除操作をすると、再び駆動部材50が作動し、駆動軸51が上記とは逆方向に回転し、それに連動して回動部61が矢印M方向とは反対方向に回動し、ロックアーム部63の係止部75が、ロッド40のロック溝45から抜け出るので、ロッド40の押し込み不能状態が解除される。この状態で再びロッド40がバネ部材57の付勢力に抗して押圧されると、カム突部49が第2嵌合溝55bから外れてガイド溝55cにガイドされ、ロッド40が回転しながら筒状部17の先端開口から突出し、カム突部49が第1嵌合溝55aに嵌合することで、ロッド40が筒状部17の先端開口から突出した状態に保持されると共に(図4(a),(d))、係合片43が回転して、その長手方向が開閉体5の係合溝8の溝方向に整合することで(図8(b)参照)、開閉体5の閉じ状態のロックが解除される。また、ロッド40によって開閉体5が押されて、固定部材3の開口部3aから開閉体5を所定高さ持ち上げるので(リフター動作)、開閉体5を手動で開くことができる。なお、ロックアーム部63の係止部75が、ロッド40のロック溝45から外れた状態では、ロック部材60の重心Gの位置が、係止部75がロック溝45に係止した状態でのロック部材60の重心Gの位置よりも、回動部61の回動方向とは反対側に移動すると共に(図7(a),(b)参照)、駆動部材50の駆動軸51の回転抵抗や、回動部61の回動軸部67と本体部材15のアーム支持孔35との摺動抵抗等によって、係止部75がロック溝45から離れた状態に保持される。 On the other hand, for example, when the driver of the automobile unlocks the opening / closing body 5, the drive member 50 operates again, the drive shaft 51 rotates in the opposite direction to the above, and the pivoting portion 61 interlocks with it. The locking portion 75 of the lock arm portion 63 is disengaged from the locking groove 45 of the rod 40, so that the non-pushable state of the rod 40 is released. In this state, when the rod 40 is pressed again against the biasing force of the spring member 57, the cam projection 49 is separated from the second fitting groove 55b and guided by the guide groove 55c, and the rod 40 is rotated while rotating. The rod 40 is held in a state where it protrudes from the tip end opening of the cylindrical portion 17 by projecting from the tip end opening of the rod shaped portion 17 and fitting the cam projection 49 into the first fitting groove 55a (FIG. a), (d), the engagement piece 43 is rotated, and its longitudinal direction is aligned with the groove direction of the engagement groove 8 of the opening / closing body 5 (see FIG. 8B); The closed lock is released. Further, since the opening and closing body 5 is pushed by the rod 40 and the opening and closing body 5 is lifted from the opening 3a of the fixed member 3 by a predetermined height (lifter operation), the opening and closing body 5 can be manually opened. When the locking portion 75 of the lock arm portion 63 is out of the locking groove 45 of the rod 40, the position of the center of gravity G of the locking member 60 is in a state where the locking portion 75 is locked to the locking groove 45. The rotational resistance of the drive shaft 51 of the drive member 50 while moving to the opposite side of the rotational direction of the rotational portion 61 from the position of the center of gravity G of the lock member 60 (see FIGS. 7A and 7B). The locking portion 75 is held apart from the lock groove 45 by the sliding resistance between the pivot shaft portion 67 of the pivoting portion 61 and the arm support hole 35 of the main body member 15 or the like.
 ところで、図9の仮想線で示すように、ロッド40が筒状部17の先端開口から突出して、開閉体5が固定部材3の開口部3aから持ち上げられた状態で、誤って駆動部材50が操作されて、駆動軸51及び回動部61を介して、ロック部材60のロックアーム部63が回動して、係止部75がロッド40の基端よりも外側に配置されると、開閉体5を押しても、ロッド40を押し込むことができない状態となる。この状態で、駆動部材50の駆動軸51が回転駆動不能となると、ロック部材60が回動不能となるため、ロッド40を押し込むことができなくなり、その結果、開閉体5を閉じた状態にロックできなくなる。これに対して、この実施形態においては、図9に示すように、ロッド40の基端部外周には、基端に向かって次第に高さが低くなるテーパ面46が形成されているので、上記のような状態となっても、ロッド40を押し込むことで、テーパ面46を介して係止部75が押圧されるため、ロック部材60を回動させることができる。そのため、ロッド40を再度押し込むことができ、ロック溝45にロックアーム部63の係止部75を係止させて、開閉体5をロック状態にすることができる。 By the way, as shown by an imaginary line in FIG. 9, the rod 40 protrudes from the tip opening of the cylindrical portion 17 and the drive member 50 is erroneously lifted in a state where the open / close member 5 is lifted from the opening 3a of the fixing member 3. When the lock arm portion 63 of the lock member 60 is rotated via the drive shaft 51 and the rotation portion 61 and the locking portion 75 is disposed outside the base end of the rod 40, the open / close operation is performed. Even if the body 5 is pushed, the rod 40 can not be pushed in. In this state, when the drive shaft 51 of the drive member 50 can not be driven to rotate, the lock member 60 can not be rotated, so that the rod 40 can not be pushed in. As a result, the open / close member 5 is locked in the closed state become unable. On the other hand, in this embodiment, as shown in FIG. 9, a tapered surface 46 whose height gradually decreases toward the proximal end is formed on the outer periphery of the proximal end of the rod 40. Even in such a state, the locking portion 60 can be rotated because the locking portion 75 is pressed via the tapered surface 46 by pushing the rod 40. Therefore, the rod 40 can be pushed in again, and the locking portion 75 of the lock arm portion 63 can be locked in the lock groove 45 to bring the open / close member 5 into the locked state.
 そして、この開閉装置10においては、図6や図7に示すように、駆動部材50駆動軸51が、ロッド40の軸方向(ロッド40の軸心C1に沿った方向)と並列に配置されるように、駆動部材50が本体部材15に保持されている。そのため、駆動軸51がロッド40の軸方向に交差して配置された場合と比べて、ロッド40の軸方向から見たときに、本体部材15の、ロッド40の軸方向に直交する方向の長さ(本体部材15の長手方向Aに沿った長さ)を短くすることができると共に、ロック部材60の回動部61の内側に、駆動部材50の駆動軸51が配置されているので、回動部61の外側に駆動軸51が配置された場合に比べて、省スペース化することができる。その結果、開閉装置全体として小型化を図ることができ、開閉装置10の設置スペースを低減することができる。 And in this opening-closing device 10, as shown in FIG.6 and FIG.7, the drive member 50 drive shaft 51 is arrange | positioned in parallel with the axial direction (direction along the axial center C1 of the rod 40) of the rod 40. Thus, the drive member 50 is held by the main body member 15. Therefore, the length of the main body member 15 in the direction orthogonal to the axial direction of the rod 40 when viewed from the axial direction of the rod 40 as compared with the case where the drive shaft 51 is disposed to intersect the axial direction of the rod 40 (The length along the longitudinal direction A of the main body member 15) can be shortened, and the drive shaft 51 of the drive member 50 is disposed inside the pivoting portion 61 of the lock member 60, Compared with the case where the drive shaft 51 is disposed outside the moving part 61, space saving can be realized. As a result, the overall size of the switchgear can be reduced, and the installation space of the switchgear 10 can be reduced.
 また、この実施形態においては、図9に示すように、駆動部材50の駆動軸51は、駆動部材50の一端側から、ロッド40の先端とは反対側に向けて延出し、かつ、ロッド40の先端とは反対側に配置されており、また、ロック溝45は、ロッド40の先端とは反対側に形成されている。 Further, in this embodiment, as shown in FIG. 9, the drive shaft 51 of the drive member 50 extends from the one end side of the drive member 50 to the side opposite to the tip of the rod 40 and the rod 40 The lock groove 45 is formed on the side opposite to the tip of the rod 40.
 ここで、仮に、ロッド40の軸方向途中にロック溝45が形成されている場合には、ロッド40の押し込みストロークを長く確保しなければ、ロック部材60にロックさせることができないため、本体部材15の奥行方向(ロッド40の軸方向に沿った方向)の大型化を招く。また、ロッド40の先端とは反対側に、ロック溝45を形成したとしても、駆動部材50の駆動軸51が、ロッド40の先端側に向けて突出している場合には、駆動部材50を、ロッド基端側から後退した位置に配置する必要があり、駆動部材50の分だけ、本体部材15の奥行方向が大きくなる。更に、ロック溝45がロッド40の軸方向の先端側に形成されは、ロッド40が筒状部17の先端開口から突出したときに、ロック溝45が露出する場合には、ロック溝45から、水等が本体部材15内に侵入する可能性があるため、本体部材15の筒状部17を長く形成する必要がある。いずれの場合も、本体部材15の奥行方向を大きくする必要性があった。 Here, if the lock groove 45 is formed in the middle of the rod 40 in the axial direction, the lock member 60 can not be locked unless a long pressing stroke of the rod 40 is ensured. This increases the size in the depth direction (direction along the axial direction of the rod 40). Further, even if the lock groove 45 is formed on the side opposite to the tip of the rod 40, when the drive shaft 51 of the drive member 50 protrudes toward the tip side of the rod 40, the drive member 50 is It is necessary to arrange at a position retracted from the rod proximal end side, and the depth direction of the main body member 15 becomes larger by the amount of the drive member 50. Furthermore, when the lock groove 45 is formed on the tip end side in the axial direction of the rod 40 and the lock groove 45 is exposed when the rod 40 protrudes from the tip end opening of the cylindrical portion 17, from the lock groove 45, Since water or the like may intrude into the main body member 15, it is necessary to form the cylindrical portion 17 of the main body member 15 long. In any case, there is a need to increase the depth direction of the main body member 15.
 これに対して、この実施形態においては、上述したように、駆動部材50の駆動軸51は、駆動部材50の一端側から、ロッド40の先端とは反対側に向けて延出し、かつ、ロッド40の先端とは反対側に配置され、ロック溝45は、ロッド40の先端とは反対側に形成されているので、ロック溝45を原因とする本体部材15内への水等の侵入を阻止しつつ、ロッド40の軸方向長さを短くすることができ、かつ、そのロック溝45に、ロック部材60のロックアーム部53に確実に係止させることができ、本体部材15の奥行方向の長さを短くして、開閉装置10の更なる小型化を図ることができる。また、この実施形態のように、ロッド40の先端が斜め上向きで、先端と反対側の基端側は斜め下向きに配置された状態で、ロック部材60の回動部61と、駆動軸51との間にグリスが塗布される場合には、グリスを駆動部材50内に入り込みにくくすることができる(仮に、駆動部材50の駆動軸51の延出方向が、ロッド40の基端側から先端側に向かう場合には、グリスがたれてきて駆動部材50内に入り込みやすい)。 On the other hand, in this embodiment, as described above, the drive shaft 51 of the drive member 50 extends from the one end side of the drive member 50 to the side opposite to the tip of the rod 40, and The lock groove 45 is disposed on the side opposite to the tip of the rod 40, and the lock groove 45 is formed on the side opposite to the tip of the rod 40. Therefore, intrusion of water etc. into the body member 15 due to the lock groove 45 is prevented. Therefore, the axial length of the rod 40 can be shortened, and the lock arm 53 of the lock member 60 can be reliably engaged with the lock groove 45, and the depth direction of the main body member 15 can be reduced. By shortening the length, the switch 10 can be further miniaturized. Further, as in this embodiment, the rotating portion 61 of the lock member 60 and the drive shaft 51 are disposed with the tip of the rod 40 obliquely upward and the base end opposite to the tip obliquely downward. When grease is applied between the two, it is difficult to get the grease into the drive member 50 (provisionally, the extension direction of the drive shaft 51 of the drive member 50 is from the proximal end side of the rod 40 to the distal end side). In the case of going to (G), grease tends to fall on and easily enter the driving member 50).
 更に、この実施形態においては、図6や図7に示すように、ロック部材60のロックアーム部63は、くの字状に屈曲した屈曲部77を有しており、ロックアーム部63がロッド40のロック溝45に係止する方向に、駆動部材50の駆動軸51によって、ロック部材60の回動部61が回動する際に、前記屈曲部77の頂部77aが、回動部61の回動方向(矢印M方向)に向くように配置されている。そのため、ロッド40の軸心C1と、駆動部材50の駆動軸51の軸心C2(回動軸部67の軸心C2)とを、本体部材15の幅方向B(本体部材15の長手方向Aに直交する方向)に近づけて配置することができ、開閉装置10の小型化をより効果的に図ることができる。また、ロッド40のロック溝45に対する、ロックアーム部63の係止状態をしっかりと維持することができる。 Furthermore, in this embodiment, as shown in FIG. 6 and FIG. 7, the lock arm portion 63 of the lock member 60 has a bent portion 77 bent in a V shape, and the lock arm portion 63 is a rod When the pivoting portion 61 of the lock member 60 is pivoted by the drive shaft 51 of the drive member 50 in the direction of locking in the lock groove 45 of the fork 40, the top 77a of the bent portion 77 It is arrange | positioned so that it may turn to the rotation direction (arrow M direction). Therefore, the axial center C1 of the rod 40 and the axial center C2 of the drive shaft 51 of the drive member 50 (the axial center C2 of the rotation shaft 67) are shown in the width direction B of the main body member 15 (the longitudinal direction A of the main body member 15). Can be disposed close to the direction perpendicular to the direction of .beta. Further, the locked state of the lock arm portion 63 with respect to the lock groove 45 of the rod 40 can be firmly maintained.
 また、この実施形態においては、図6に示すように、ロック部材60は、ロックアーム部63の係止部75が、ロッド40のロック溝45に係止した状態において、ロック部材60の自重によって作用する回動方向(矢印M方向)が、同ロックアーム部63の係止部75が前記ロック溝45に係止する方向になるように、駆動軸51に保持されているので、ロックアーム部63をロッド40のロック溝45に係止した状態に、よりしっかりと維持することができる。 Moreover, in this embodiment, as shown in FIG. 6, the locking member 60 is locked by the weight of the locking member 60 in a state where the locking portion 75 of the lock arm portion 63 is locked to the locking groove 45 of the rod 40. The lock arm portion is held by the drive shaft 51 such that the acting rotational direction (arrow M direction) is the direction in which the locking portion 75 of the lock arm portion 63 is locked to the lock groove 45. 63 can be more securely maintained in the locked state in the lock groove 45 of the rod 40.
 更に、この実施形態においては、ロック部材60は、回動部61から延出し、ロッド40のロック溝45とロックアーム部63との係止状態を解除可能な、解除アーム部65を有している。そのため、ロック溝45にロックアーム部63の係止部75が係止した状態で、駆動部材50の駆動軸51が回転しない非常時(バッテリー切れ等の場合)において、解除アーム部65を操作することで、ロック溝45とロックアーム部63の係止部75との係止状態を解除することができ、開閉体5を開くことができる。また、ロックアーム部63は、解除アーム部65に対して、ロッド40の先端側に位置ずれして配置されているので、ロッド40の全長を短くすることができ、開閉装置10の小型化を図ることができる(解除アーム部65とロックアーム部63とが同じ軸方向位置に設けられている場合には、ロッド40をロックアーム部63の位置まで伸ばさなければならないので、ロッド40を長くする必要がある)。 Furthermore, in this embodiment, the lock member 60 includes a release arm portion 65 which extends from the rotation portion 61 and can release the locked state of the lock groove 45 of the rod 40 and the lock arm portion 63. There is. Therefore, in a state in which the drive shaft 51 of the drive member 50 does not rotate (in the case of a battery exhaustion or the like) in a state where the locking portion 75 of the lock arm portion 63 is locked in the lock groove 45, the release arm portion 65 is operated. Thus, the locked state between the lock groove 45 and the locking portion 75 of the lock arm portion 63 can be released, and the opening / closing body 5 can be opened. In addition, since the lock arm portion 63 is disposed on the tip end side of the rod 40 with respect to the release arm portion 65, the entire length of the rod 40 can be shortened, and thus the opening / closing device 10 can be miniaturized. (If the release arm 65 and the lock arm 63 are provided at the same axial position, the rod 40 must be extended to the position of the lock arm 63, so the rod 40 should be elongated There is a need).
 図10及び図11には、本発明に係る開閉体の開閉装置の、他の実施形態が示されている。なお、前記実施形態と実質的に同一部分には同符号を付してその説明を省略する。 10 and 11 show another embodiment of the switchgear of the switchgear according to the present invention. It is to be noted that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
 この実施形態における開閉体の開閉装置10A(以下、単に「開閉装置10A」という)は、駆動部材及びロック部材の構造が前記実施形態と異なっている。 The opening / closing device 10A (hereinafter simply referred to as "opening / closing device 10A") in this embodiment is different from the above embodiment in the structure of the drive member and the lock member.
 図10及び図11に示すように、この実施形態では、駆動部材50Aの駆動軸51Aのの外周に、外歯ギヤ53が固着されている。また、図11に示すように、外歯ギヤ53の中央には、平坦面54aを有する軸圧入孔54が形成されており、駆動軸51の平坦面51aを整合させて、同駆動軸51が軸圧入孔54に圧入されることで、軸圧入孔54内で駆動軸51Aが回転規制された状態で、駆動軸51Aの外周に外歯ギヤ53が固着される。一方、ロック部材60Aの回動部61Aは、円環状のリング形状をなしており、その内周に前記外歯ギヤ53に歯合する内歯ギヤ62が形成されている。すなわち、回動部61Aの内側に、外周に外歯ギヤ53を有する駆動軸51Aが配置されており、ロック部材60Aが駆動部材50の駆動軸51に保持されている。 As shown in FIGS. 10 and 11, in this embodiment, the external gear 53 is fixed to the outer periphery of the drive shaft 51A of the drive member 50A. Further, as shown in FIG. 11, a shaft press-in hole 54 having a flat surface 54a is formed at the center of the external gear 53, and the flat surface 51a of the drive shaft 51 is aligned. By being press-fitted into the shaft press-in hole 54, the external gear 53 is fixed to the outer periphery of the drive shaft 51A in a state where the rotation of the drive shaft 51A is restricted in the shaft press-in hole 54. On the other hand, the rotating portion 61A of the lock member 60A has an annular ring shape, and an internal gear 62 meshing with the external gear 53 is formed on the inner periphery thereof. That is, the drive shaft 51A having the external gear 53 on the outer periphery is disposed inside the pivoting portion 61A, and the lock member 60A is held by the drive shaft 51 of the drive member 50.
 そして、駆動軸51Aが回転駆動して、外歯ギヤ53が回転すると、外歯ギヤ53に歯合する内歯ギヤ62を介して、回動部61Aが連動して回動するので、ロック部材60Aのロックアーム部63が、ロッド40のロック溝45に係脱する。なお、外歯ギヤ53と内歯ギヤ62との間には、潤滑用のグリスが塗布されている。また、前記実施形態と同様に、ロッド40の軸方向から見たときに、ロッド40の軸心C1と、駆動軸51Aの軸心C2とは、本体部材15の長手方向Aに直交する幅方向Bに対して、位置ずれして配置されている(図11参照)。 Then, when the drive shaft 51A is rotationally driven and the external gear 53 is rotated, the rotating portion 61A is interlocked and rotated via the internal gear 62 meshing with the external gear 53, so the lock member The lock arm portion 63 of 60 A engages with the lock groove 45 of the rod 40. Note that lubricating grease is applied between the external gear 53 and the internal gear 62. Further, as viewed from the axial direction of the rod 40, the axial center C1 of the rod 40 and the axial center C2 of the drive shaft 51A are in the width direction orthogonal to the longitudinal direction A of the main body member 15 as in the embodiment. It is disposed out of position with respect to B (see FIG. 11).
 そして、この実施形態においては、駆動軸51Aは、その外周に外歯ギヤ53を有しており、回動部61Aは環状をなし、その内周に前記外歯ギヤ53に歯合する内歯ギヤ62を有しているので、例えば、回動部の外周に外歯ギヤがあり、これに駆動軸の外周に設けた外歯ギヤが歯合する場合と比べて、回動部61A及び駆動軸51Aを小型化することができる。また、駆動軸51Aと回動部61Aとのギヤ比を上げて、ロッド40のロック溝45に対するロックアーム部63の係止力を向上させることができる。更に、回動部61Aの内周の内歯ギヤ62と、駆動軸51Aの外周の外歯ギヤ53との間に塗布されるグリスが、環状をなした回動部61の内周に保持されるため、グリスが回動部61Aの外側に出にくくなり、駆動部材50内に、より入り込みにくくすることができる。 Further, in this embodiment, the drive shaft 51A has an external gear 53 on the outer periphery thereof, the rotating portion 61A has an annular shape, and an internal tooth that meshes with the external gear 53 on its inner periphery. Since the gear 62 is provided, for example, there is an external gear on the outer periphery of the rotating portion, and the rotating portion 61A and the drive are compared with the case where the external gear provided on the outer periphery of the drive shaft meshes with this. The shaft 51A can be miniaturized. Further, the gear ratio between the drive shaft 51A and the pivoting portion 61A can be increased to improve the locking force of the lock arm portion 63 with respect to the lock groove 45 of the rod 40. Furthermore, grease applied between the internal gear 62 on the inner periphery of the pivoting portion 61A and the external gear 53 on the outer periphery of the drive shaft 51A is held on the inner periphery of the annular pivoting portion 61. Therefore, the grease is less likely to come out of the rotating portion 61A, and can be made more difficult to enter into the driving member 50.
 なお、本発明は、上述した実施形態に限定されるものではなく、本発明の要旨の範囲内で、各種の変形実施形態が可能であり、そのような実施形態も本発明の範囲に含まれる。 The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the present invention, and such embodiments are also included in the scope of the present invention. .
