At the center of the locked body 33, a center hole that fits into the restriction shaft 35 and a key groove that is formed continuously from the center hole are formed. The reference numerals of the central hole and the keyway are omitted.

被係止体33が一般的な平歯車と異なる構成は、図5に示すように、被係止突起40の形状であり、各被係止溝41の形状である。被係止突起40の形状と被係止溝41の形状は対応するため、便宜上、被係止溝41の形状を主に説明する。一つの被係止溝41は、径方向内方側面41a,41aと、径方向途中側面41b,41bと、径方向外方側面41c,41cにより形成されている。径方向内方側面41a,41a、径方向途中側面41b,41b、および径方向外方側面41c,41cは、何れも規制軸35に沿う平面である。 The configuration in which the locked body 33 differs from a general spur gear is the shape of the locked projection 40 and the shape of each locked groove 41, as shown in FIG. Since the shape of the locked projection 40 and the shape of the locked groove 41 correspond to each other, the shape of the locked groove 41 will be mainly described for convenience. One locked groove 41 is formed by radially inner side surfaces 41a, 41a, radially intermediate side surfaces 41b, 41b, and radially outer side surfaces 41c, 41c. The radial inner side surfaces 41a, 41a, the radial intermediate side surfaces 41b, 41b, and the radial outer side surfaces 41c, 41c are all flat surfaces along the restriction shaft 35.

径方向内方側面41a,41aでは、径方向中心側が鈍角状に尖るよう傾斜して形成されている。径方向途中側面41b,41bでは、径方向途中部分までが径方向外方ほどわずかに互いに近付くよう形成されている。径方向外方側面41c,41cでは、径方向外方ほど互いに離間するよう傾斜されている。被係止突起40で対応させると、各被係止突起40は、径方向内方部40aを裾広がりに形成され、径方向途中部40bを括れ形状に形成され、径方向外方部40cを尖端状に形成されている。 The radially inner side surfaces 41a, 41a are formed so that the center side in the radial direction is inclined so as to have an obtuse angle. The radial intermediate side surfaces 41b, 41b are formed so that the radial intermediate portions thereof are slightly closer to each other outward in the radial direction. The radially outer side surfaces 41c, 41c are inclined so as to be spaced apart from each other toward the radially outer side. Corresponding to the locked protrusions 40, the locked protrusions 40 are formed such that the radially inner portion 40a is formed to have a widened skirt, the radial middle portion 40b is constricted, and the radial outer portion 40c is formed.

このキャリーケース1では、キャリーケース本体2の上部且つ後方部である隅部に、回動中心機構6が備えた回動中心軸7が、厚み方向Tに挿通支持されている。すなわちキャリーケース本体2は、厚み方向Tに直交する方向である前方に押して運搬することができる。キャリーケース本体2は厚みtよりも前後方向の長さの方が長いから、ユーザ55はキャリーケース本体2を安定させた姿勢で押して運搬することができる。 In the carry case 1, a rotation center shaft 7 included in the rotation center mechanism 6 is inserted and supported in the thickness direction T at a corner portion which is an upper portion and a rear portion of the carry case body 2. That is, the carry case body 2 can be pushed and transported in the front direction, which is the direction orthogonal to the thickness direction T. Since the length of the carrying case body 2 in the front-rear direction is longer than the thickness t, the user 55 can push and carry the carrying case body 2 in a stable posture.

本実施形態の操作ハンドル装置3は、操作部材17の操作により、アーム4の伸縮のロックおよびロック解除、ハンドル本体10(アーム4)の回動のロックおよびロック解除ができるよう構成されている。ユーザ55がキャリーケース本体2を運搬する際、ユーザ55の体型や運搬のし易さによって、ユーザ55は、アーム4の長さを変更したり、キャリーケース本体2に対するハンドル本体10の傾斜角度を変更したりすることができる。ユーザ55の体型等に応じてアーム4の長さを変更したり、ハンドル本体10の傾斜角度を変更したりすることで、運搬がし易くなる。 The operation handle device 3 of the present embodiment is configured such that the operation member 17 can be operated to lock and unlock the extension and contraction of the arm 4, and lock and unlock the rotation of the handle body 10 (arm 4). When the user 55 carries the carry case body 2, the user 55 can change the length of the arm 4 or change the inclination angle of the handle body 10 with respect to the carry case body 2 depending on the body shape of the user 55 and the ease of carrying. It can be changed. By changing the length of the arm 4 or changing the inclination angle of the handle body 10 according to the body shape of the user 55, it becomes easy to carry.

図3に示すように、アーム4が最短縮姿勢であり、操作部材17が基準位置にある場合、一端側内ストッパ部22Aの一端側当接面22aは、一端側ストッパ20の一端受面20aに当接している。連結部5Aの一端面5cは、他端側ストッパ21の他端面21bに当接している。ここで、操作部材17の基準位置とは、操作部材17が長手方向の何れにも移動していない位置であり、操作部材17の一方面が把持ハンドル5の一方面に面一であり、操作部材17の他方面が、把持ハンドル5の他方面に面一の位置である。 As shown in FIG. 3, when the arm 4 is in the shortest position and the operation member 17 is at the reference position, the one end side contact surface 22a of the one end side inner stopper portion 22A is the one end side receiving surface 20a of the one end side stopper 20. Is in contact with. One end surface 5c of the connecting portion 5A is in contact with the other end surface 21b of the other end side stopper 21. Here, the reference position of the operating member 17 is a position where the operating member 17 does not move in any of the longitudinal directions, one surface of the operating member 17 is flush with one surface of the grip handle 5, The other surface of the member 17 is flush with the other surface of the grip handle 5.

アーム4が最短縮姿勢で、操作部材17が基準位置にあるとき、保持部材12は係止孔18aに係合した突出位置にあり、係脱部材14はその先端を被係止体33の被係止溝41に係止させた接触位置にある。このため、アーム4は伸長も回動も不可能である。 When the arm 4 is in the shortest position and the operation member 17 is at the reference position, the holding member 12 is at the protruding position engaged with the locking hole 18a, and the engagement/disengagement member 14 has its tip covered by the locked body 33. It is in the contact position where it is locked in the locking groove 41. Therefore, the arm 4 cannot be extended or rotated.

ユーザ55が、アーム4を最短縮姿勢から最伸長姿勢とする場合の、操作ハンドル装置3の操作を説明する。アーム4において、外側アーム部材18に対して内側アーム部材19を長手方向に操作できない状態は、保持部材12が保持用ばね体13の弾性により付勢されて、係止孔18aに係止した突出位置にある場合である(例えば、図3参照)。したがって、アーム4を最短縮姿勢から最伸長姿勢とするには、保持部材12を係止孔18aからアーム4の内方へ後退させる必要がある。保持部材12を係止孔18Aからアーム4の内方へ後退させるには、ユーザ55が保持解除操作部17Bを、ユーザ55が保持解除操作部17Bを、長手方向一方側へ押圧する。 The operation of the operation handle device 3 when the user 55 changes the arm 4 from the shortest posture to the most extended posture will be described. In the state in which the inner arm member 19 cannot be operated in the longitudinal direction with respect to the outer arm member 18 in the arm 4, the holding member 12 is urged by the elasticity of the holding spring body 13 and is locked in the locking hole 18a. This is the case (see FIG. 3, for example). Therefore, in order to change the arm 4 from the shortest position to the most extended position, the holding member 12 needs to be retracted inward of the arm 4 from the locking hole 18a. In order to retract the holding member 12 inward of the arm 4 from the locking hole 18A, the user 55 pushes the holding release operating portion 17B and the user 55 pushes the holding release operating portion 17B to one side in the longitudinal direction.

保持解除操作部17Bが長手方向一方側へ押圧されると、保持解除操作部17Bの移動に伴って差渡部材45が長手方向一方側へ移動し、差渡部材45の移動とともに被操作杆11が長手方向一方側へ移動する。被操作杆11の先端部(一端側)には押圧部11Aがあって、被操作杆11が長手方向一方側へ移動すると、押圧部11Aの傾斜面が、保持部材12の内方に設けられた被押圧部(符合省略)を、アーム4の内方に向けて押圧する。そうすると、被押圧部とともに保持部材12が係止孔18aに対しアーム4の内方に後退し、保持部材12がアーム4の内方に没した後退位置となる。 When the holding release operating portion 17B is pressed to one side in the longitudinal direction, the transfer member 45 moves to one side in the longitudinal direction as the holding release operating portion 17B moves, and the operated rod 11 moves with the movement of the transferring member 45. Moves to one side in the longitudinal direction. There is a pressing portion 11A at the tip (one end side) of the operated rod 11, and when the operated rod 11 moves to one side in the longitudinal direction, the inclined surface of the pressing portion 11A is provided inside the holding member 12. The pressed portion (reference numeral omitted) is pressed toward the inside of the arm 4. Then, together with the pressed portion, the holding member 12 retracts inward of the arm 4 with respect to the locking hole 18a, and the holding member 12 comes to a retracted position in which the holding member 12 is retracted inward of the arm 4.

保持部材12が後退位置となると、保持部材12は内側アーム部材19を保持しなくなる。このため、内側アーム部材19は、外側アーム部材18に対して長手方向(長手方向他方側)へ移動でき、ユーザ55は把持ハンドル5を把持してアーム4を伸長させることができる。 When the holding member 12 is in the retracted position, the holding member 12 does not hold the inner arm member 19. Therefore, the inner arm member 19 can move in the longitudinal direction (on the other side in the longitudinal direction) with respect to the outer arm member 18, and the user 55 can grip the grip handle 5 and extend the arm 4.

ユーザ55がアーム4を伸長させている途中においても、保持部材12は保持用ばね体13によってアーム4の外方へ向けて付勢されている。このため、保持部材12は、外側アーム部材18の内面に当接して摺動する。図6に示すように、一端側内ストッパ部22Aの他端側当接面22bが他端側ストッパ21の他端受面21aに当接した時点で、保持部材12が、長手方向他方側端の係止孔18aに対応する位置に到達してその係止孔18aから突出し、外側アーム部材18に係止する。保持部材12は、係止孔18aに係止した突出位置にあることで、内側アーム部材19は長手方向に移動不可となる。 Even while the user 55 is extending the arm 4, the holding member 12 is biased toward the outside of the arm 4 by the holding spring body 13. Therefore, the holding member 12 abuts on the inner surface of the outer arm member 18 and slides. As shown in FIG. 6, when the other end side contact surface 22b of the one end side inner stopper portion 22A comes into contact with the other end receiving surface 21a of the other end side stopper 21, the holding member 12 moves to the other end in the longitudinal direction. It reaches a position corresponding to the locking hole 18a, projects from the locking hole 18a, and locks to the outer arm member 18. Since the holding member 12 is in the projecting position locked in the locking hole 18a, the inner arm member 19 cannot move in the longitudinal direction.

内側アーム部材19を長手方向他方側へ向けて移動させる際(長手方向一方側へ向けて移動させる際も同様)には、図8に示すように、操作部材17は、長手方向一方側へ向けて移動した保持解除位置とされる。しかしながら、保持部材12が係止孔18aに係止すること、すなわち、被押圧部が保持用ばね体13の弾性によりアーム4の外方へ向けて移動することにより、被操作杆11が長手方向他方側へ向けて押される。そうなると、差渡部材45が長手方向他方側へ向けて移動し、差渡部材45とともに操作部材17が長手方向他方側から長手方向一方側へ向けて移動し、図13に示すように、操作部材17が基準位置に復帰する。すなわち、操作部材17の保持解除位置は、保持部材12の後退位置に対応した位置である。 When moving the inner arm member 19 toward the other side in the longitudinal direction (the same applies when moving toward the one side in the longitudinal direction), as shown in FIG. 8, the operating member 17 is directed toward the one side in the longitudinal direction. Moved to the holding release position. However, since the holding member 12 is locked in the locking hole 18a, that is, the pressed portion moves toward the outside of the arm 4 due to the elasticity of the holding spring body 13, the operated rod 11 moves in the longitudinal direction. It is pushed toward the other side. Then, the transfer member 45 moves toward the other side in the longitudinal direction, the operating member 17 moves together with the transfer member 45 from the other side in the longitudinal direction toward one side in the longitudinal direction, and as shown in FIG. 17 returns to the reference position. That is, the holding release position of the operating member 17 is a position corresponding to the retracted position of the holding member 12.

ユーザ55が、アーム4を最伸長姿勢から最短縮姿勢にしようとする場合では、再び保持解除操作部17Bを長手方向一方側へ向けて押す。そうすることで、保持部材12が突出位置から後退位置へ移動する。このため、アーム4を、外側アーム部材18に対して内側アーム部材19が最大限に収容された最短縮姿勢とすることができる。 When the user 55 wants to move the arm 4 from the most extended posture to the most shortened posture, the holding release operation portion 17B is pushed again toward the one side in the longitudinal direction. By doing so, the holding member 12 moves from the protruding position to the retracted position. Therefore, the arm 4 can be in the shortest posture in which the inner arm member 19 is maximally accommodated with respect to the outer arm member 18.

アーム4の最伸長姿勢において、ユーザ55がハンドル本体10(アーム4)を、キャリーケース本体2に対して所望の角度に傾斜させる場合の、操作ハンドル装置3の操作を説明する。例えば、図3および図4を参照して、係脱部材14は係止用ばね体15の弾性により長手方向一方側へ付勢されており、操作部材17が基準位置にあるときには、係脱部材14は、その先端部14aを被係止体33の何れかひとつの被係止溝41(被係止突起40)に係止させた接触位置にある。このように、操作部材17の基準位置は、保持部材12の突出位置に対応した位置でもある。 The operation of the operation handle device 3 when the user 55 tilts the handle body 10 (arm 4) at a desired angle with respect to the carry case body 2 in the most extended posture of the arm 4 will be described. For example, referring to FIGS. 3 and 4, the engagement/disengagement member 14 is biased toward one side in the longitudinal direction by the elasticity of the locking spring body 15, and when the operation member 17 is at the reference position, the engagement/disengagement member 14 is released. 14 is at a contact position where the tip portion 14a is locked in any one of the locked grooves 41 (locked projection 40) of the locked body 33. As described above, the reference position of the operation member 17 is also a position corresponding to the protruding position of the holding member 12.

係脱部材14の先端部14aが被係止体33の被係止溝41に係止していると、被係止体33は、規制軸35回りに回転不可能な状態にある。被係止体33の回転が阻止されていると、被係止体33と同軸にある規制平歯車34が回転不可能であり、規制平歯車34に噛合している中径平歯車26が回転不可能であり、中径平歯車26と同軸の小径平歯車27が回転不可能であり、小径平歯車27に噛合している大径平歯車25が回転不可能である。 When the tip end portion 14 a of the engagement/disengagement member 14 is locked in the locked groove 41 of the locked body 33, the locked body 33 is in a state in which it cannot rotate around the regulation shaft 35. When the locked body 33 is prevented from rotating, the regulation spur gear 34 coaxial with the locked body 33 cannot rotate, and the medium diameter spur gear 26 meshing with the regulation spur gear 34 rotates. It is impossible, the small diameter spur gear 27 coaxial with the medium diameter spur gear 26 cannot rotate, and the large diameter spur gear 25 meshing with the small diameter spur gear 27 cannot rotate.

大径平歯車25が回転不可能であると、キャリーケース本体2に取付けられている回動中心軸7が回転不可能であるから、ハンドル本体10がキャリーケース本体2に対して回転不可能である。すなわち、係脱部材14の先端部14aが被係止体33の被係止溝41に係止していると、ハンドル本体10がキャリーケース本体2に対して回転不可能である。 If the large diameter spur gear 25 cannot rotate, the rotation center shaft 7 attached to the carry case body 2 cannot rotate, so that the handle body 10 cannot rotate with respect to the carry case body 2. is there. That is, when the tip end portion 14 a of the engaging/disengaging member 14 is locked in the locked groove 41 of the locked body 33, the handle body 10 cannot rotate with respect to the carry case body 2.

したがって、ハンドル本体10をキャリーケース本体2に対して回転可能とするためには、被係止体33を回転可能とする必要があり、被係止体33を回転可能とするためには、係脱部材14が接触位置から離脱位置となるよう、係脱部材14を操作する。このために、ユーザ55は、図14に示すように、操作部材17の連繋手段操作部17Aを、長手方向一方側から長手方向他方側へ向けて移動させて、操作部材17を係止解除位置とする。そうすると、操作部材17に連結された差渡部材45が長手方向他方側へ移動し、差渡部材45に連結されている被操作杆11が長手方向他方側へ移動する。 Therefore, in order to make the handle body 10 rotatable with respect to the carry case body 2, it is necessary to make the locked body 33 rotatable. The engagement/disengagement member 14 is operated so that the removal member 14 moves from the contact position to the removal position. For this reason, the user 55 moves the connecting means operating portion 17A of the operating member 17 from one side in the longitudinal direction to the other side in the longitudinal direction as shown in FIG. And Then, the delivery member 45 connected to the operation member 17 moves to the other side in the longitudinal direction, and the operated rod 11 connected to the delivery member 45 moves to the other side in the longitudinal direction.

ところで、係脱部材14が接触位置にある場合、連繋手段16は次に説明する状態にある。すなわち、被操作杆11には、連繋手段16の連結部材51の一端がピン53を介して連結されており、連結部材51の他端は、ピン53を介して規制体50に連結され、規制体50は、接近用ばね52によって、被係止歯50aを係止歯14bに係止する方向に付勢されている。いっぽうで、図9、図11に示すように、規制体50の一端面は、一端側内ストッパ部22Aの底壁220の上面に当接していて、規制体50はそれ以上係脱部材14に接近するのを制限されている。このため、規制体50の被係止歯50aは、係止歯14bに係止していない。 By the way, when the engaging/disengaging member 14 is in the contact position, the connecting means 16 is in the state described below. That is, one end of the connecting member 51 of the connecting means 16 is connected to the operated rod 11 via the pin 53, and the other end of the connecting member 51 is connected to the regulating body 50 via the pin 53. The body 50 is biased by the approaching spring 52 in a direction in which the locked tooth 50a is locked to the locking tooth 14b. On the other hand, as shown in FIGS. 9 and 11, one end surface of the restricting body 50 is in contact with the upper surface of the bottom wall 220 of the inner stopper portion 22A on one end side, and the restricting body 50 is further attached to the engaging/disengaging member 14. You are restricted from approaching. Therefore, the locked tooth 50a of the regulation body 50 is not locked to the locking tooth 14b.

このような連繋手段16の状態において、ユーザ55が、連繋手段操作部17Aを長手方向一方側から長手方向他方側へ向けて移動させ、操作部材17を係止解除位置とする。そうすると、被操作杆11が長手方向他方側へ移動する。被操作杆11が長手方向他方側へ移動すると、連繋手段16の連結部材51が、ピン53を中心として回動し、接近用ばね52の弾性に付勢されつつ長手方向他方側へ移動する。規制体50は、接近用ばね52の弾性により付勢されていることで、拡幅部110側のピン53回りに回動して係脱部材14にその側方から接近し、被係止歯50aが係止歯14bに係合する。 In such a state of the connecting means 16, the user 55 moves the connecting means operating portion 17A from one side in the longitudinal direction to the other side in the longitudinal direction to bring the operating member 17 to the unlocking position. Then, the operated rod 11 moves to the other side in the longitudinal direction. When the operated rod 11 moves to the other side in the longitudinal direction, the connecting member 51 of the connecting means 16 rotates about the pin 53 and moves to the other side in the longitudinal direction while being biased by the elasticity of the approaching spring 52. Since the restricting body 50 is biased by the elasticity of the approaching spring 52, the restricting body 50 rotates around the pin 53 on the widening portion 110 side to approach the engaging/disengaging member 14 from the side thereof, and the locked tooth 50a. Engage the locking teeth 14b.

被係止歯50aが係止歯14bに係合すると、その係合力により、被操作杆11の移動に伴って、係脱部材14を長手方向他方側へ向けて移動させられる。ゆえに、係脱部材14の先端部14aが被係止体33の被係止溝41に対し、長手方向他方側へ外れ、係脱部材14が離脱位置に移動する。係脱部材14の先端部14aが被係止体33の被係止溝41から外れると、被係止体33は規制軸35回りに回転可能になる。 When the locked tooth 50a engages with the locking tooth 14b, the engagement force moves the engagement/disengagement member 14 toward the other side in the longitudinal direction as the operated rod 11 moves. Therefore, the tip end portion 14a of the engagement/disengagement member 14 disengages from the engaged groove 41 of the engaged body 33 to the other side in the longitudinal direction, and the engagement/disengagement member 14 moves to the disengagement position. When the tip end portion 14 a of the engagement/disengagement member 14 is disengaged from the locked groove 41 of the locked body 33, the locked body 33 becomes rotatable around the regulation shaft 35.

したがって、回動中心軸7がその軸心回り回転可能となり、ハンドル本体10がキャリーケース本体2に対して回転可能となる。このためユーザ55は、キャリーケース本体2の運搬に際して、ハンドル本体10をキャリーケース本体2に対し、ユーザ55にとって好みの角度に調節可能となる。 Therefore, the rotation center shaft 7 can rotate around its axis, and the handle body 10 can rotate with respect to the carry case body 2. Therefore, the user 55 can adjust the handle body 10 with respect to the carry case body 2 at an angle desired by the user 55 when carrying the carry case body 2.

しかしながら、係脱部材14の先端部14aが被係止体33の被係止溝41に対して外れたままであると、ハンドル本体10をキャリーケース本体2に対し、ユーザ55にとって都合よい角度に調節しても、その角度が保持されない。そこでユーザ55は、操作部材17の保持解除操作部17Bを長手方向一方側に押し、操作部材17を基準位置に復帰させる。 However, if the tip end portion 14a of the engagement/disengagement member 14 remains disengaged from the locked groove 41 of the locked body 33, the handle body 10 is adjusted to an angle convenient for the user 55 with respect to the carry case body 2. However, the angle is not maintained. Therefore, the user 55 pushes the holding release operation portion 17B of the operation member 17 to one side in the longitudinal direction to return the operation member 17 to the reference position.

操作部材17を、接近用ばね52の弾性に抗して基準位置まで移動させることで、その分だけ被操作杆11が長手方向一方側へ移動する。これに伴い、被操作杆11に連繋手段16を介して一体的に連繋されている係脱部材14は、長手方向一方側へ移動する。そうすると、規制体50が底壁220に当接し、規制体50が底壁220に沿ってアーム4の外方に向けて移動する。これにより、被係止歯50aが係止歯14bから離脱する。そうなると、係脱部材14は被操作杆11に対して長手方向に移動可能となり、長手方向一方側へ向けて移動して、先端部14aが、被係止体33の何れかの被係止溝41に係止する。先端部14aが被係止体33の被係止溝41に係止することで、被係止体33は回転不可能になり、キャリーケース本体2に対するハンドル本体10の傾斜角度が、ユーザ55の好みの角度に固定される。 By moving the operating member 17 to the reference position against the elasticity of the approaching spring 52, the operated rod 11 is moved by that amount to one side in the longitudinal direction. Along with this, the engagement/disengagement member 14 that is integrally connected to the operated rod 11 via the connecting means 16 moves to one side in the longitudinal direction. Then, the regulation body 50 contacts the bottom wall 220, and the regulation body 50 moves toward the outside of the arm 4 along the bottom wall 220. As a result, the locked tooth 50a is disengaged from the locking tooth 14b. Then, the engagement/disengagement member 14 becomes movable in the longitudinal direction with respect to the operated rod 11, moves toward one side in the longitudinal direction, and the tip end portion 14 a moves into any of the engaged grooves of the engaged body 33. Lock at 41. Since the tip end portion 14a is locked in the locked groove 41 of the locked body 33, the locked body 33 becomes unrotatable, and the inclination angle of the handle body 10 with respect to the carry case body 2 is set by the user 55. The angle is fixed to your liking.

なお、操作部材17を係止解除位置から基準位置まで移動させても、保持用ばね体13の弾性に抗して被押圧部を移動させない。このため、保持部材12は突出位置にあって、内側アーム部材19は長手方向に移動できない。すなわちアーム4では、最伸長姿勢が保持される。 Even if the operating member 17 is moved from the unlocked position to the reference position, the pressed portion is not moved against the elasticity of the holding spring body 13. Therefore, the holding member 12 is in the protruding position, and the inner arm member 19 cannot move in the longitudinal direction. That is, the arm 4 holds the most extended posture.

被係止体33の外周部には、複数の被係止溝41が形成されている。このため、ユーザ55にとって都合のよいハンドル本体10の傾斜角度に対応するように、何れかの被係止溝41に係脱部材14の先端部14aが係止して、ハンドル本体10を固定することができる。 A plurality of locked grooves 41 are formed on the outer peripheral portion of the locked body 33. Therefore, the tip portion 14a of the engagement/disengagement member 14 is locked in any of the locked grooves 41 so as to correspond to the inclination angle of the handle body 10 that is convenient for the user 55, and the handle body 10 is fixed. be able to.

上記の説明では、ハンドル本体10をキャリーケース本体2に対して傾斜させる場合を説明している。しかしながら、ユーザ55は、ハンドル本体10を、キャリーケース本体2に対して必ずしも傾斜させる必要はない。具体的には、ユーザ55はハンドル本体10を、キャリーケース本体2の上下方向に沿わせて用いることもできる。 In the above description, the case where the handle body 10 is tilted with respect to the carry case body 2 has been described. However, the user 55 does not necessarily have to tilt the handle body 10 with respect to the carry case body 2. Specifically, the user 55 can also use the handle body 10 along the vertical direction of the carry case body 2.

本実施形態のキャリーケース1では、ハンドル本体10を伸縮させることができるとともに、キャリーケース本体2に対する角度調整ができる。このため、図15に示すように、平坦な面を運搬するのみならず、ユーザ55が階段56においてキャリーケース1を運搬する場合には、キャスタを用いず、キャリーケース本体2を階段56に接触させるようにして運搬することができる。昇り階段、下り階段でハンドル本体10の傾斜角度を変更して用いることもできる。この際には、ユーザ55は、連繋手段操作部17Aを押す操作をすることで、ハンドル本体10の傾斜角度を容易に変更させられ、保持解除操作部17Bを押すことで容易にハンドル本体10の長さを変更させられる。 In the carry case 1 of this embodiment, the handle body 10 can be expanded and contracted, and the angle with respect to the carry case body 2 can be adjusted. Therefore, as shown in FIG. 15, when the user 55 not only carries a flat surface but also carries the carry case 1 on the stairs 56, the carry case main body 2 is brought into contact with the stairs 56 without using casters. It can be carried in such a way. It is also possible to change the inclination angle of the handle body 10 for use in the ascending stairs and the descending stairs. At this time, the user 55 can easily change the inclination angle of the handle main body 10 by pressing the connecting means operating unit 17A, and easily press the holding release operation unit 17B. You can change the length.

なお、キャリーケース本体2を階段56に接触させるようにして運搬する場合を想定すれば、キャリーケース本体2の外面(例えば角部)に、合成樹脂製の滑材を取付けておく構成を採用できる。該滑材を階段56に接触させるようにすれば、ユーザ55はキャリーケース1の運搬を楽に行える。 Assuming a case in which the carry case body 2 is brought into contact with the stairs 56 for transportation, a construction in which a synthetic resin lubricant is attached to the outer surface (for example, a corner portion) of the carry case body 2 can be adopted. .. By bringing the sliding material into contact with the stairs 56, the user 55 can easily carry the carrying case 1.

本実施形態の操作ハンドル装置3では、保持部材12がアーム4の内方に後退した後退位置にある場合、係脱部材14は接触位置にあって、回動中心軸7は回転不可能である。換言すれば、保持部材12の後退位置は、連繋手段16の規制体50が係脱部材14から離脱しており、係止歯14bと被係止歯50aとは噛合していない状態である。 In the operation handle device 3 of the present embodiment, when the holding member 12 is in the retracted position retracted inward of the arm 4, the engagement/disengagement member 14 is in the contact position and the rotation center shaft 7 cannot rotate. .. In other words, the retracted position of the holding member 12 is a state in which the restricting body 50 of the connecting means 16 is disengaged from the engagement/disengagement member 14, and the locking teeth 14b and the locked teeth 50a are not meshed.

すなわち、係脱部材14は係止用ばね体15の弾性により接触位置にあるから、回動中心軸7は回転不可能である。保持部材12がアーム4の内方に後退した後退位置にある場合として、ユーザ55が保持解除操作部17Bを長手方向一方側へ移動させた場合、ユーザ55が保持解除操作部17Bを長手方向一方側へ移動させて内側アーム部材19を外側アーム部材18に対して移動させている途中(保持部材12が外側アーム部材18の内面に当接している)の場合がある。 That is, since the engagement/disengagement member 14 is in the contact position due to the elasticity of the locking spring body 15, the rotation center shaft 7 cannot rotate. When the holding member 12 is in the retracted position retracted inward of the arm 4, when the user 55 moves the holding release operating portion 17B to one side in the longitudinal direction, the user 55 moves the holding releasing operation portion 17B in one longitudinal direction. There is a case where the inner arm member 19 is being moved to the side and is being moved with respect to the outer arm member 18 (the holding member 12 is in contact with the inner surface of the outer arm member 18).

要するに、本実施形態に係る操作ハンドル装置3は、アーム4と、被操作杆11と、保持部材12と、保持用ばね体13と、係脱部材14と、係止用ばね体15と、連繋手段16と、操作部材17とを備えている。アーム4は、外側アーム部材18と外側アーム部材18の長手方向に移動可能な内側アーム部材19とを有する。アーム4は、その長手方向一端側がキャリーケース本体2に回動中心機構6を介して回動可能に取付けられている。被操作杆11は、アーム4の長手方向に沿って設けられ内側アーム部材19とともにアーム4の長手方向に沿って移動可能に構成されている。 In short, the operation handle device 3 according to the present embodiment connects the arm 4, the operated rod 11, the holding member 12, the holding spring body 13, the engagement/disengagement member 14, and the locking spring body 15 to each other. It comprises a means 16 and an operating member 17. The arm 4 has an outer arm member 18 and an inner arm member 19 movable in the longitudinal direction of the outer arm member 18. One end of the arm 4 in the longitudinal direction is rotatably attached to the carry case body 2 via a rotation center mechanism 6. The operated rod 11 is provided along the longitudinal direction of the arm 4 and is configured to be movable along with the inner arm member 19 along the longitudinal direction of the arm 4.

保持部材12は、アーム4の最伸長姿勢、および最短縮姿勢の少なくとも二つの姿勢の何れかを保持する部材である。この場合、最伸長姿勢は、アーム4の内側から外側へ突出することで外側アーム部材18に係合して、外側アーム部材18に対して内側アーム部材19が長手方向に最大限に突出した状態である。最短縮姿勢は、外側アーム部材18に対して内側アーム部材19が長手方向に最大限に収容された状態である。 The holding member 12 is a member that holds either one of the most extended posture and the most shortened posture of the arm 4. In this case, in the most extended posture, the arm 4 is engaged with the outer arm member 18 by protruding from the inner side to the outer side, and the inner arm member 19 is maximally protruded in the longitudinal direction with respect to the outer arm member 18. Is. The most shortened posture is a state in which the inner arm member 19 is maximally accommodated in the longitudinal direction with respect to the outer arm member 18.

保持用ばね体13は、保持部材12が外側アーム部材18側に突出して外側アーム部材18に係止した突出位置に向けて保持部材12を付勢している。係脱部材14は、回動中心機構6に係脱自在である。係止用ばね体15は、係脱部材14が回動中心機構6に接触してこれを非回転に保持する接触位置となる方向に係脱部材14を付勢している。 The holding spring body 13 biases the holding member 12 toward a protruding position where the holding member 12 projects toward the outer arm member 18 and is locked by the outer arm member 18. The engagement/disengagement member 14 is detachable from the rotation center mechanism 6. The locking spring body 15 biases the engagement/disengagement member 14 in a direction in which the engagement/disengagement member 14 comes into contact with the rotation center mechanism 6 to hold it in a non-rotational position.

操作部材17は、アーム4の長手方向に沿って一方向に移動した保持解除位置と、アーム4の長手方向に沿って他方向に移動した係止解除位置と、保持解除位置および係止解除位置の間の基準位置とに切替え可能に構成されている。すなわち操作部材17は、保持部材12がアームの内側に没するよう後退した後退位置と突出位置との間の距離に対応した距離だけ、被操作杆11をアーム4の長手方向に沿って一方向および他方向に移動操作可能に構成されている。また、操作部材17は、係脱部材14の接触位置と係脱部材14が回動中心機構6から離脱した離脱位置との間の距離に対応した所定距離だけ、被操作杆11をアーム4の長手方向に沿って一方向および他方向に移動操作可能に構成されている。この操作部材17は、被操作杆11に連結されている。 The operation member 17 has a holding release position that moves in one direction along the longitudinal direction of the arm 4, a locking release position that moves in the other direction along the longitudinal direction of the arm 4, a holding release position and a locking release position. It is configured to be switchable to a reference position between. That is, the operating member 17 moves the operated rod 11 in one direction along the longitudinal direction of the arm 4 by a distance corresponding to the distance between the retracted position where the holding member 12 is retracted inside the arm and the protruding position. And is configured to be movable in the other direction. Further, the operating member 17 moves the operated rod 11 of the arm 4 by a predetermined distance corresponding to the distance between the contact position of the engagement/disengagement member 14 and the disengagement position where the engagement/disengagement member 14 is disengaged from the rotation center mechanism 6. It is configured to be movable in one direction and the other direction along the longitudinal direction. The operating member 17 is connected to the operated rod 11.

連繋手段16は、操作部材17を他方向へ所定距離だけ移動させる移動操作により、被操作杆11および係脱部材14を連繋させるよう構成されている。連繋手段16は、被操作杆11および係脱部材14を連繋させることで、被操作杆11および係脱部材14をともに他方向へ移動させて、接触位置にある係脱部材14を離脱位置とする機能を有する。 The connecting means 16 is configured to connect the operated rod 11 and the engagement/disengagement member 14 by a moving operation of moving the operation member 17 in the other direction by a predetermined distance. The connecting means 16 connects the operated rod 11 and the engagement/disengagement member 14 to each other to move the operated rod 11 and the engagement/disengagement member 14 in the other direction, so that the engagement/disengagement member 14 at the contact position is moved to the detachment position. Have the function to

操作部材17の保持解除位置は、保持部材12の後退位置に対応し、操作部材17の係止解除位置は、係脱部材14の離脱位置に対応している。操作部材17の基準位置は、保持部材12の突出位置に対応し、且つ係脱部材14の接触位置に対応している。 The holding release position of the operation member 17 corresponds to the retracted position of the holding member 12, and the locking release position of the operation member 17 corresponds to the detached position of the engagement/disengagement member 14. The reference position of the operating member 17 corresponds to the protruding position of the holding member 12 and the contact position of the engaging/disengaging member 14.

上記構成において、係止用ばね体15の弾性により、係脱部材14が回動中心機構6を非回転に保持した接触位置にある状態で、操作部材17を所定距離だけ他方向へ移動させると、操作部材17の移動に伴い被操作杆11がアーム4の長手方向に沿って他方向へ移動する。操作部材17を所定距離だけ他方向へ移動させると、連繋手段16によって被操作杆11に係脱部材14が連繋して係脱部材14も他方向へ移動し、接触位置にある係脱部材14が離脱位置となる。係脱部材14が離脱位置となると、アーム4がその長手方向一端側を基準に、回動中心機構6を介して被取付体に回動可能となる。 In the above configuration, when the engaging member 14 is in the contact position where the engaging/disengaging member 14 holds the rotation center mechanism 6 in a non-rotating state due to the elasticity of the locking spring body 15, when the operating member 17 is moved in the other direction by a predetermined distance. With the movement of the operating member 17, the operated rod 11 moves in the other direction along the longitudinal direction of the arm 4. When the operating member 17 is moved in the other direction by a predetermined distance, the engaging/disengaging member 14 is connected to the operated rod 11 by the connecting means 16 and the engaging/disengaging member 14 is also moved in the other direction, so that the engaging/disengaging member 14 at the contact position. Is the departure position. When the engagement/disengagement member 14 is at the disengaged position, the arm 4 becomes rotatable with respect to one end side in the longitudinal direction of the arm 4 via the rotation center mechanism 6 to the attached body.

上記構成において、操作部材17が保持解除位置にあるとき、保持部材12は後退位置にあってアーム4の伸縮を規制しない。操作部材17が係止解除位置にあるとき、係脱部材14は離脱位置にあって回動中心機構6の動きを規制しない。操作部材17が基準位置にあるとき、保持部材12は突出位置にあって外側アーム部材18側に突出して外側アーム部材18に係止することでアーム4の伸縮を規制する。操作部材17が基準位置にあるとき、係脱部材14は接触位置にあって回動中心機構6を非回転に保持する。 In the above configuration, when the operation member 17 is in the holding release position, the holding member 12 is in the retracted position and does not regulate the expansion and contraction of the arm 4. When the operation member 17 is in the unlocked position, the engagement/disengagement member 14 is in the disengaged position and does not regulate the movement of the rotation center mechanism 6. When the operation member 17 is at the reference position, the holding member 12 is at the protruding position, protrudes toward the outer arm member 18 side, and is locked to the outer arm member 18, thereby restricting the expansion and contraction of the arm 4. When the operation member 17 is at the reference position, the engagement/disengagement member 14 is at the contact position and holds the rotation center mechanism 6 in a non-rotating state.

本発明に係る操作ハンドル装置は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。例えば、上記実施形態では、操作ハンドル装置をキャリーケースに用いた場合を説明した。しかしながら、本発明の操作ハンドル装置は、運搬台車、歩行補助車等の運搬具の操作ハンドル装置としてこれらに取付けることができる。また、自転車に敷設させて長さ変更および角度変更可能な操作ハンドル装置として用いることが考えられる。 The operation handle device according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the case where the operation handle device is used for the carry case has been described. However, the operation handle device of the present invention can be attached to these as an operation handle device of a carrier such as a carrier truck and a walking assistance vehicle. Further, it can be considered to be laid on a bicycle and used as an operation handle device whose length and angle can be changed.

キャリーケースやその他の運搬具に用いる場合、アームは一対で設けることに限定されず、一本であってもよい。上記連繋手段は歯どうしの係止により被操作杆と係脱部材とを連繋させる構成としたが、圧接により被操作杆と係脱部材とを連繋させる構成を採用することができる。 When used in a carry case or other carrier, the arms are not limited to being provided in a pair and may be one arm. The above-mentioned connecting means is configured to connect the operated rod and the engagement/disengagement member by locking the teeth, but it is also possible to employ a configuration in which the operated rod and the engagement/disengagement member are connected by pressure contact.

操作部材は、連繋手段操作部および保持解除操作部を一体的に設けてなる構成を説明した。しかしながら、差渡部材を操作するためには、別体であってもよい。さらに、連繋手段操作部および保持解除操作部は一個に限定されず、特に連繋手段操作部は、ユーザが握るという操作に着目して、把持ハンドルの長手方向に離間して配置する構成を採用できる。 The operating member has been described as having a structure in which the connecting means operating portion and the holding release operating portion are integrally provided. However, it may be a separate body for operating the delivery member. Furthermore, the connecting means operating part and the holding release operating part are not limited to one, and in particular, the connecting means operating part can be arranged so as to be separated from each other in the longitudinal direction of the grip handle, focusing on the operation of being gripped by the user. ..

上記実施形態では、係脱部材14の係止部として、鋸歯状に連続した多数の係止歯14bが形成されてなる場合を例示した。しかしながら、図16および図17に示すように、係止部は、係脱部材14の長手方向に離間し、その長手方向途中部分の二箇所に形成された係止歯60,61とすることもできる。係脱部材14の長手方向において、係止歯60,61どうしの離間距離は、アーム4の最短縮姿勢と最伸長姿勢の間の、内側アーム部材19の移動距離に対応する距離に設定されている。 In the above-described embodiment, the case where the engagement portion of the engagement/disengagement member 14 is formed of a large number of engagement teeth 14b that are continuous in a sawtooth shape is illustrated. However, as shown in FIGS. 16 and 17, the locking portions may be locking teeth 60 and 61 formed at two positions in the middle of the engaging/disengaging member 14 in the longitudinal direction. it can. In the longitudinal direction of the engagement/disengagement member 14, the distance between the locking teeth 60 and 61 is set to a distance corresponding to the movement distance of the inner arm member 19 between the shortest position and the most extended position of the arm 4. There is.

各係止歯60,61は、三角形の凹部として形成されている。すなわち各係止歯60,61は、係脱部材14の外面に形成された傾斜面60a,61aと、傾斜面60a,61aの端から立上がる係止面60b,61bとを備えている。係止歯60,61どうしの離間距離Lは、係止面60b,61bの間の距離として特定される。なお、係止歯60,61の間は平坦面14cとされている。 Each locking tooth 60, 61 is formed as a triangular recess. That is, each locking tooth 60, 61 has an inclined surface 60a, 61a formed on the outer surface of the engagement/disengagement member 14 and an engaging surface 60b, 61b rising from the end of the inclined surface 60a, 61a. The separation distance L between the locking teeth 60 and 61 is specified as the distance between the locking surfaces 60b and 61b. A flat surface 14c is formed between the locking teeth 60 and 61.

図18ないし図20に示すように、規制体62は、内ストッパ22に内装され、係脱部材14の側方に配置されており、直方体の板状に形成されている。規制体62において、係止歯60,61に対向する面に、規制体62の位置に応じて何れかの係止歯60,61に係脱自在な被係止歯63が形成されている。被係止歯63は、それぞれの係止歯60,61に対応するよう、三角形に形成されている。規制体62には、係脱部材14に対向する面に、このような被係止歯63が一つ形成されている。 As shown in FIGS. 18 to 20, the restricting body 62 is provided inside the inner stopper 22, is disposed laterally of the engaging/disengaging member 14, and is formed in a rectangular parallelepiped plate shape. On the surface of the restriction body 62 facing the locking teeth 60, 61, a locked tooth 63 that can be engaged with and disengaged from any of the locking teeth 60, 61 is formed according to the position of the restriction body 62. The locked teeth 63 are formed in a triangular shape so as to correspond to the locking teeth 60 and 61, respectively. One such locked tooth 63 is formed on the surface of the restriction body 62 facing the engagement/disengagement member 14.

本実施形態では、係止孔18aは、アーム4の最短縮姿勢および最伸長姿勢に対応する位置にのみ形成されていればよい。したがって、本実施形態では、係止孔18aは、外側アーム部材18の二箇所に形成されている。他の部分の構成については、図1ないし図15に基づいて説明した前記実施形態と同様であるから、同一の符合を付してその説明を繰返さない。 In the present embodiment, the locking holes 18a may be formed only at the positions corresponding to the most shortened posture and the most extended posture of the arm 4. Therefore, in this embodiment, the locking holes 18 a are formed at two positions on the outer arm member 18. The configuration of the other parts is the same as that of the embodiment described with reference to FIGS. 1 to 15, and therefore, the same reference numerals are given and the description thereof will not be repeated.

上記構成の係脱部材14および規制体62が組込まれた操作ハンドル装置によれば、アーム4の最短縮姿勢において、規制体62の被係止歯63は、長手方向一方側(ばね座環14A側)の係止歯60に係止する。アーム4の最伸長姿勢において、規制体62の被係止歯63は、長手方向他方側の係止歯61に係止する。具体的には、被係止歯63は、係止歯60,61の係止面60b,61bの何れかに係止することで、内側アーム部材19の移動が規制される。 According to the operation handle device in which the engaging/disengaging member 14 and the restricting body 62 having the above-described configurations are incorporated, the locked tooth 63 of the restricting body 62 is located on one side in the longitudinal direction (the spring seat ring 14A) in the most shortened posture of the arm 4. Side) locking teeth 60. In the most extended posture of the arm 4, the locked tooth 63 of the regulation body 62 locks with the locking tooth 61 on the other side in the longitudinal direction. Specifically, the locked tooth 63 is locked to any one of the locking surfaces 60b and 61b of the locking teeth 60 and 61 to restrict the movement of the inner arm member 19.

例えば、アーム4を最短縮姿勢から最伸長姿勢とするために、ユーザ55が外側アーム部材18に対して内側アーム部材19を移動させる際に、規制体62の被係止歯63は、係止歯60,61の間の平坦面14cに摺動しつつ移動する。被係止歯63が係止歯60,61の間の面を摺動しても、係止歯60,61の間は平坦面14cであるから、規制体62の移動中に、規制体62の挙動が抑えられる。また、係止歯60,61の間を平坦面14cとしていることで、被係止歯63が係止歯60,61の間を移動する際の摺動音を、確実に抑制することができる。 For example, when the user 55 moves the inner arm member 19 with respect to the outer arm member 18 to move the arm 4 from the shortest position to the most extended position, the locked teeth 63 of the restricting body 62 are locked. It moves while sliding on the flat surface 14c between the teeth 60 and 61. Even if the locked tooth 63 slides on the surface between the locking teeth 60 and 61, the flat surface 14c is formed between the locking teeth 60 and 61. Behavior is suppressed. In addition, since the flat surface 14c is formed between the locking teeth 60 and 61, it is possible to reliably suppress the sliding sound when the locked tooth 63 moves between the locking teeth 60 and 61. ..

図16ないし図20に表した実施形態では、係止歯60,61は、アーム4の最短縮姿勢と最伸長姿勢に対応する位置である、二つの位置に配置した。しかしながら、例えば係止歯60,61の間の中間位置に、同じ構成(形状)の係止歯を、さらに一つ形成することもできる。この場合では、係止孔18aを、アーム4の最短縮姿勢、最伸長姿勢、およびその中間に対応する位置に形成しておくことで、アーム4を、最短縮姿勢、最伸長姿勢、およびその中間位置にある姿勢として用いることができる。他の作用効果は、上記各実施形態と同様であるので、その説明を繰返さない。 In the embodiment shown in FIGS. 16 to 20, the locking teeth 60 and 61 are arranged at two positions, which are positions corresponding to the most shortened posture and the most extended posture of the arm 4. However, it is also possible to further form one locking tooth having the same configuration (shape) at an intermediate position between the locking teeth 60 and 61, for example. In this case, the locking hole 18a is formed at a position corresponding to the most shortened posture, the most stretched posture, and the intermediate position of the arm 4, so that the arm 4 has the most shortened posture, the most stretched posture, and its position. It can be used as a posture in an intermediate position. Other operational effects are the same as those in the above-described embodiments, and therefore description thereof will not be repeated.

本発明の操作ハンドル装置は、外側アーム部材と該外側アーム部材の長手方向に移動可能な内側アーム部材とを有して長手方向一端側が被取付体に回動中心機構を介して回動可能に取付けられるアームと、該アームの長手方向に沿って設けられ前記内側アーム部材とともにアームの長手方向に沿って移動可能な被操作杆と、前記アームの内側から外側へ突出することで前記外側アーム部材に係合して、前記外側アーム部材に対して前記内側アーム部材が長手方向に最大限に突出した前記アームの最伸長姿勢、および前記外側アーム部材に対して前記内側アーム部材が長手方向に最大限に収容された前記アームの最短縮姿勢の少なくとも二つの姿勢の何れかを保持する保持部材と、該保持部材が前記外側アーム部材側に突出して該外側アーム部材に係止した突出位置に、該保持部材を付勢する保持用ばね体と、前記回動中心機構に係脱自在な係脱部材と、該係脱部材が前記回動中心機構に接触してこれを非回転に保持する接触位置となる方向に、該係脱部材を付勢する係止用ばね体と、前記保持部材が前記アームの内側に没するよう後退した後退位置と前記突出位置との間の距離に対応した距離、且つ前記係脱部材の接触位置と前記係脱部材が前記回動中心機構から離脱した離脱位置との間の距離に対応した距離だけ、前記被操作杆を前記アームの長手方向に沿って一方向および他方向に移動操作可能であって、前記被操作杆に連結された操作部材と、該操作部材を他方向へ所定距離だけ移動させる移動操作により前記被操作杆および前記係脱部材を連繋させることで、前記被操作杆および前記係脱部材をともに他方向へ移動させて、前記接触位置にある前記係脱部材を前記離脱位置とする連繋手段とを備えたことを特徴とする。 The operation handle device of the present invention has an outer arm member and an inner arm member that is movable in the longitudinal direction of the outer arm member, and one end side in the longitudinal direction is rotatable with respect to the mounted body via a rotation center mechanism. An arm to be attached, an operated rod provided along the longitudinal direction of the arm and movable along with the inner arm member along the longitudinal direction of the arm, and the outer arm member by protruding from the inner side to the outer side of the arm And the inner arm member is maximally extended in the longitudinal direction with respect to the outer arm member, and the inner arm member is maximal in the longitudinal direction with respect to the outer arm member. A holding member that holds any one of at least two postures of the most shortened posture of the arm housed in a limit, and a projecting position in which the holding member projects toward the outer arm member side and is locked to the outer arm member, A holding spring body that urges the holding member, an engagement/disengagement member that can be engaged/disengaged with the rotation center mechanism, and a contact with which the engagement/disengagement member contacts the rotation center mechanism and holds it in a non-rotating manner. In the direction of the position, a distance corresponding to the distance between the locking spring body for urging the engaging/disengaging member and the retracted position in which the holding member retracts so as to be recessed inside the arm and the protruding position. In addition, the operated rod is moved along the longitudinal direction of the arm by a distance corresponding to the distance between the contact position of the engagement/disengagement member and the disengagement position where the engagement/disengagement member is disengaged from the rotation center mechanism. Direction and another direction, the operating member connected to the operated rod and the operated rod and the engagement member are connected by a moving operation for moving the operating member in the other direction by a predetermined distance. By doing so, the operated rod and the engagement/disengagement member are both moved in the other direction, and there is provided a connecting means for bringing the engagement/disengagement member at the contact position to the separation position.

上記構成において、保持用ばね体の弾性により、保持部材がアームの内側から外側へ突出することで外側アーム部材に係合した突出位置にあると、内側アーム部材が外側アーム部材に対して伸縮不可能な状態に保持される。保持用ばね体の弾性に抗して操作部材を所定距離だけ一方向へ移動させると、操作部材の移動に伴い被操作杆がアームの長手方向に沿って一方向へ移動し、突出位置にある保持部材が後退位置となって、アームは最伸長姿勢と最短縮姿勢との間で、外側アーム部材に対して内側アーム部材が伸縮可能となる。 In the above structure, the elasticity of the holding spring body causes the holding member to project from the inside of the arm to the outside so that the holding member is at the protruding position where it is engaged with the outside arm member. It is kept in a possible state. When the operating member is moved by a predetermined distance in one direction against the elasticity of the holding spring body, the operated rod moves in one direction along the longitudinal direction of the arm along with the movement of the operating member and is in the projecting position. When the holding member is in the retracted position, the inner arm member can extend and contract with respect to the outer arm member between the most extended posture and the most shortened posture.

係止用ばね体の弾性により、係脱部材が回動中心機構を非回転に保持した接触位置にある状態で、操作部材を所定距離だけ他方向へ移動させると、操作部材の移動に伴い被操作杆がアームの長手方向に沿って他方向へ移動するとともに、連繋手段によって被操作杆に係脱部材が連繋して係脱部材も他方向へ移動し、接触位置にある係脱部材が離脱位置となって、アームがその長手方向一端側を基準に、回動中心機構を介して被取付体に回動可能となる。 Due to the elasticity of the locking spring body, when the operating member is moved in the other direction by a predetermined distance while the engagement/disengagement member is in the contact position where the rotation center mechanism is held in the non-rotational state, the operation member is moved along with the movement. The operating rod moves in the other direction along the longitudinal direction of the arm, and the engaging/disengaging member is connected to the operated rod by the connecting means to move the engaging/disengaging member in the other direction, and the engaging/disengaging member at the contact position is released. When the arm is in the position, the arm can be rotated with respect to the attached body through the rotation center mechanism with reference to the one end side in the longitudinal direction.
