Description

ベビーカーstroller
　本発明は、折り畳み可能なベビーカーに係り、とりわけ、意図せず折り畳み動作が開始してしまうことを効果的に防止することができるベビーカーに関する。 The present invention relates to a foldable baby stroller, and more particularly to a baby stroller that can effectively prevent unintentional folding operation from starting.
　例えばＪＰ２００９－３５０６６Ａに開示されているように、折り畳み可能な折り畳み式のベビーカーが広く利用されている。折り畳み可能なベビーカーには、ベビーカーを展開状態にするためのロック手段が設けられており、このロック手段を操作することにより、ベビーカーの折り畳み操作が可能となる。また、意図せずベビーカーの折り畳み動作が開始してしまうことを防止するため、ロック手段の操作を規制する操作規制手段が、多くのベビーカーに設けられている。 For example, as disclosed in JP2009-35066A, foldable baby strollers are widely used. The foldable baby stroller is provided with a lock means for bringing the baby stroller into an unfolded state. By operating the lock means, the baby stroller can be folded. Further, in order to prevent the stroller folding operation from starting unintentionally, many baby strollers are provided with operation restriction means for restricting the operation of the lock means.
　ところで、折り畳み可能なベビーカーにおいては、乳幼児から目を離すことなく折り畳み操作を行うことができるよう、ロック手段および操作規制手段の操作を含めたベビーカーを折り畳むための全操作が、容易に実行され得ることが要望されている。典型的には、保護者が乳幼児を一方の手で抱き上げた状態において、他方の手のみによって、ベビーカーを折り畳むための全操作が行われることが好ましい。ただしその一方で、操作規制手段が容易に操作可能であるとすると、誤操作等によって、意図せずに折り畳み動作が開始されてしまう可能性が増してしまう。 By the way, in the foldable baby stroller, all operations for folding the baby stroller including operations of the lock means and the operation restricting means can be easily performed so that the folding operation can be performed without taking the eyes off the infant. It is requested. Typically, in a state where the guardian holds the infant with one hand, it is preferable that the entire operation for folding the stroller is performed only by the other hand.

Each third link member 34 is pivotally connected to a middle portion of the rear leg 24 at a part thereof, and is pivotally connected to a lower portion of the first link member 26 at the other portion. Yes.
　このような構成からなるフレーム部２０に対し、ハンドル３６が揺動可能に連結されている。ハンドル３６は、フレーム部２０から延び出す一対の主部３７と、一対の主部３７の間を幅方向延びて一対の主部３７を連結する中間部３８と、を有しており、全体としてＵ字状に形成されている。ハンドル３６は、Ｕ字の両端部、すなわち主部３７の中間部３８とは反対側の端部を、対応する側の第３リンク材３４に回動可能（揺動可能）に連結されている。なお、図４に示すように、ハンドル３６の第３リンク材３４に対する回動軸線（揺動中心）は、第３リンク材３４と第１リンク材２６との回動軸線、および、第１リンク材２６と第２リンク材３２との回動軸線と一致している。 The handle 36 is swingably connected to the frame portion 20 having such a configuration. The handle 36 has a pair of main portions 37 extending from the frame portion 20 and an intermediate portion 38 extending in the width direction between the pair of main portions 37 and connecting the pair of main portions 37 as a whole. It is formed in a U shape. The handle 36 is pivotally connected to the corresponding third link member 34 at both ends of the U-shape, that is, the end opposite to the intermediate portion 38 of the main portion 37. . As shown in FIG. 4, the rotation axis (swing center) of the handle 36 with respect to the third link member 34 is the rotation axis of the third link member 34 and the first link member 26, and the first link. It coincides with the rotation axis of the material 26 and the second link material 32.
　また、背面押し位置にあるハンドル３６は、図４に示すように、ハンドル３６に摺動可能に設けられた摺動保持部材３９と、アームレスト２８または第１リンク材２６に設けられた第１ハンドル保持部材２７ａと、の係合によって、第１リンク材２６と略平行に延びるように保持される。一方、対面押し位置にあるハンドル３６は、ハンドル３６に摺動可能に設けられた摺動保持部材３９と、アームレスト２８に設けられた第２ハンドル保持部材２７ｂと、の係合によって、前方上方に延びるように保持される（図１の二点鎖線を参照）。 Further, as shown in FIG. 4, the handle 36 in the back pushing position includes a sliding holding member 39 slidably provided on the handle 36 and a first handle provided on the armrest 28 or the first link member 26. By being engaged with the holding member 27a, the holding member 27a is held so as to extend substantially in parallel with the first link member 26. On the other hand, the handle 36 in the face-to-face push position moves forward and upward by engagement of a slide holding member 39 slidably provided on the handle 36 and a second handle holding member 27b provided on the armrest 28. It is held so as to extend (see the two-dot chain line in FIG. 1).
　なお、図１に示すように、ハンドル３６の右側主部３７の上方部分には、ブレーキ操作手段１３が設けられている。ブレーキ操作手段１３を操作することにより、操作伝達手段１４を介して、図示しない後輪１８の制動機構を操作することができる。 As shown in FIG. 1, the brake operation means 13 is provided in the upper part of the right main portion 37 of the handle 36. By operating the brake operating means 13, a braking mechanism for the rear wheel 18 (not shown) can be operated via the operation transmitting means 14.
　また、ベビーカー１０の横方向（幅方向）に延びる部材として、一対の前脚２２の間を連結するフットレスト１７と、一対の後脚２４の間を連結する後方連結材１９と、が設けられている。 In addition, as a member extending in the lateral direction (width direction) of the stroller 10, a footrest 17 that connects the pair of front legs 22 and a rear connection member 19 that connects the pair of rear legs 24 are provided. .
　以上のような全体構成を有したベビーカー１０は、各構成部材を互いに回動させることにより、折り畳むことができる。具体的には、背面押し位置に配置されたハンドル３６をいったん後上方に引き上げ、その後、下方に押し下げることによって、第３リンク材３４を後脚２４に対し図２において時計回り方向に回動させる。この操作にともなって、アームレスト２８および第２リンク材３２は第１リンク材２６に対し図２において時計回り方向に回動する。図３に示すように、この操作により、側面視においてハンドル３６と前脚２２とが接近して略平行に配置されるとともに、ハンドル３６の配置位置が下げられるようになる。以上のようにして、ベビーカー１０（ベビーカー本体１１）を折り畳むことができ、ベビーカー１０の前後方向および上下方向に沿った寸法を小型化することができる。一方、ベビーカー１０（ベビーカー本体１１）を折り畳み状態から展開するには、上述した折り畳み操作と逆の手順を踏めばよい。 The stroller 10 having the overall configuration as described above can be folded by rotating the constituent members with respect to each other. Specifically, the third link member 34 is rotated in the clockwise direction in FIG. 2 with respect to the rear leg 24 by once pulling up the handle 36 disposed at the rear pushing position and then lowering the handle 36 downward. . With this operation, the armrest 28 and the second link member 32 are rotated in the clockwise direction in FIG. 2 with respect to the first link member 26. As shown in FIG. 3, by this operation, the handle 36 and the front leg 22 approach each other in a side view and are arranged substantially in parallel, and the arrangement position of the handle 36 is lowered. As described above, the stroller 10 (stroller body 11) can be folded, and the size of the stroller 10 along the front-rear direction and the up-down direction can be reduced. On the other hand, in order to unfold the stroller 10 (stroller body 11) from the folded state, a procedure reverse to the above-described folding operation may be performed.
　ところで、図４に示すように、第１リンク材２６にはロック部材３０が設けられている。ロック部材３０は、第１リンク材２６の長手方向に沿って第１リンク材２６に対して摺動可能となっている。ロック部材３０は、図示しない付勢手段、例えばバネによって、第１リンク材２６の下方部分に設けられた第３リンク材３４に向けて付勢されている。そして、図４に示すように、ロック部材３０は、第３リンク材３４に嵌り込むようになっている。第１リンク材２６に設けられたロック部材３０が第３リンク材３４と係合することにより、第３リンク材３４の第１リンク材２６に対する回動が規制され、ベビーカー本体１１の折り畳み動作が規制され、ベビーカー本体１１が展開状態に保持されるようになる。 Incidentally, as shown in FIG. 4, the first link member 26 is provided with a lock member 30. The lock member 30 is slidable with respect to the first link member 26 along the longitudinal direction of the first link member 26. The lock member 30 is urged toward a third link member 34 provided in a lower portion of the first link member 26 by an urging means (not shown), for example, a spring. Then, as shown in FIG. 4, the lock member 30 is fitted into the third link member 34. When the lock member 30 provided on the first link member 26 engages with the third link member 34, the rotation of the third link member 34 relative to the first link member 26 is restricted, and the stroller body 11 is folded. The stroller main body 11 is held in the unfolded state.
　一方、ベビーカー１０には、このロック部材３０を操作する折り畳み操作機構４０が設けられている。図４に示すように、ロック部材３０は、幅方向外方に向けて延び出た受け片３１を有している。一方、折り畳み操作機構４０は、受け片３１に下方から当接する解除部材４１を有している。そして、折り畳み操作機構４０を操作すると、解除部材４１が受け片３１を介してロック部材３０を第１リンク材２６の長手方向に沿って持ち上げ、ロック部材３０と第３リンク材３４との係合を解除する。すなわち、折り畳み操作機構４０によって解除部材４１を操作することにより、ベビーカー本体１１（ベビーカー１０）を折り畳み可能にすることができる。折り畳み操作機構４０についは、折り畳み操作機構４０の操作を規制する第１操作規制機構５５および第２操作規制機構とともに、後述する。 On the other hand, the stroller 10 is provided with a folding operation mechanism 40 for operating the lock member 30. As shown in FIG. 4, the lock member 30 includes a receiving piece 31 that extends outward in the width direction. On the other hand, the folding operation mechanism 40 includes a release member 41 that comes into contact with the receiving piece 31 from below. When the folding operation mechanism 40 is operated, the release member 41 lifts the lock member 30 along the longitudinal direction of the first link member 26 via the receiving piece 31, and the engagement between the lock member 30 and the third link member 34 is performed. Is released. That is, by operating the release member 41 with the folding operation mechanism 40, the stroller body 11 (stroller 10) can be folded. The folding operation mechanism 40 will be described later together with a first operation restriction mechanism 55 and a second operation restriction mechanism that restrict the operation of the folding operation mechanism 40.
　なお、本明細書中において、ベビーカーに対する「前」、「後」、「上」および「下」の用語は、特に指示がない場合、展開状態にあるベビーカー１０に乗車する乳幼児を基準とした「前」、「後」、「上」および「下」を意味する。したがって、ベビーカー１０の「前後方向」とは、図１における紙面の左下と右上とを結ぶ方向に相当する。そして、特に指示がない限り、「前」とは、乗車した乳幼児が向く側であり、図１における紙面の右上側がベビーカー１０の前側となる。一方、ベビーカー１０の「上下方向」とは前後方向に直交するとともにベビーカー１０の接地面に直交する方向である。したがって、ベビーカー１０の接地面が水平面である場合、「上下方向」とは垂直方向をさす。また、「横方向」および「幅方向」とは、「前後方向」および「上下方向」のいずれにも直交する方向である。さらに、「右」および「左」についても、それぞれ、ベビーカー１０に乗車する乳幼児を基準とした横方向または幅方向における「右」および「左」のことを意味する。したがって、例えば右側の前脚２２および後脚２４とは、図１の手前側に示された前脚２２および後脚２４のことであり、左側の前脚２２および後脚２４とは、図１の奥側に示された前脚２２および後脚２４のことを指す。 In the present specification, the terms “front”, “rear”, “upper” and “lower” with respect to the baby stroller are based on “infant riding in the baby stroller 10 in the unfolded state” unless otherwise specified. It means “front”, “rear”, “upper” and “lower”. Therefore, the “front-rear direction” of the stroller 10 corresponds to a direction connecting the lower left and upper right of the paper surface in FIG. Unless otherwise specified, “front” refers to the side on which the infant who rides faces, and the upper right side of the page in FIG. 1 is the front side of the stroller 10. On the other hand, the “vertical direction” of the stroller 10 is a direction orthogonal to the front-rear direction and orthogonal to the contact surface of the stroller 10. Therefore, when the grounding surface of the stroller 10 is a horizontal plane, the “up and down direction” indicates a vertical direction. The “lateral direction” and the “width direction” are directions orthogonal to both the “front-rear direction” and the “up-down direction”. Furthermore, “right” and “left” also mean “right” and “left” in the lateral direction or width direction with respect to the infant riding in the stroller 10, respectively. Accordingly, for example, the right front leg 22 and the rear leg 24 are the front leg 22 and the rear leg 24 shown on the front side in FIG. 1, and the left front leg 22 and the rear leg 24 are the rear side in FIG. The front leg 22 and the rear leg 24 shown in FIG.
　次に、主に図５～図１１を参照しながら、折り畳み操作機構４０、第１操作規制機構５５および第２操作規制機構６０について詳述する。図５～図１１に示すように、折り畳み操作機構４０は、ベビーカー本体１１の折り畳み動作が規制されるようになる規制位置と、ベビーカー本体１１の折り畳み動作を可能にする解除位置と、の間を移動可能な解除部材４１と、解除部材４１に接続され、操作されることによって解除部材４１を規制位置から解除位置へ移動させる主操作部材５０と、を有している。第１操作規制機構５５および第２操作規制機構６０は、それぞれ、主操作部材５０を用いた解除部材４１の操作が規制されるロック位置と、主操作部材５０を用いた解除部材４１の操作が可能となる非ロック位置と、の間を移動可能な規制解除操作部材５６、６１を、有している。 Next, the folding operation mechanism 40, the first operation restriction mechanism 55, and the second operation restriction mechanism 60 will be described in detail with reference mainly to FIGS. As shown in FIGS. 5 to 11, the folding operation mechanism 40 is between a restriction position where the folding operation of the stroller body 11 is restricted and a release position that enables the folding operation of the stroller body 11. A movable release member 41 and a main operation member 50 that is connected to and operated by the release member 41 to move the release member 41 from the restriction position to the release position. The first operation restricting mechanism 55 and the second operation restricting mechanism 60 each have a lock position where the operation of the release member 41 using the main operation member 50 is restricted, and the operation of the release member 41 using the main operation member 50. It has the regulation release operation members 56 and 61 which can move between the non-locking positions where it becomes possible.
　まず、折り畳み操作機構４０について説明する。折り畳み操作機構４０は、規制位置（図７に示された状態）と解除位置（図８に示された状態）との間を移動可能な解除部材４１と、解除部材４１に接続された主操作部材５０と、を有するとともに、さらに、主操作部材５０の動作を解除部材４１に伝達する伝達手段４３を有している。 First, the folding operation mechanism 40 will be described. The folding operation mechanism 40 includes a release member 41 that can move between a restriction position (the state shown in FIG. 7) and a release position (the state shown in FIG. 8), and a main operation connected to the release member 41. And a transmission means 43 for transmitting the operation of the main operation member 50 to the release member 41.
　図５～図１０に示すように、折り畳み操作機構４０は、ハンドル３６に設けられている。図１～図３、図５、図６に示すように、ハンドル３６の中間部３８の中央には、ケーシング９５が設けられている。このケーシング９５と一対の筒状部材、例えば一対の金属製パイプとによって、主として、ハンドル３６が構成されている。図５および図６に示すように、ケーシング９５内に設けられた支持軸部材９６を介して、折り畳み操作機構４０の主操作部材５０が、ケーシング９５に対して回動自在に取り付けられている。主操作部材５０は、支持軸部材９６に挿通され、支持軸部材９６を中心としてケーシング９５に対して回動可能に連結された回動部５０ｂと、主操作部材５０ｂから延び出たレバー部５０ａと、を有している。レバー部５０ａは、ケーシング９５の第１開口９５ａを介してケーシング９５から延び出ており、ケーシング９５の外部から主操作部材５０を操作し得るようになっている。 As shown in FIGS. 5 to 10, the folding operation mechanism 40 is provided on the handle 36. As shown in FIGS. 1 to 3, 5, and 6, a casing 95 is provided at the center of the intermediate portion 38 of the handle 36. A handle 36 is mainly constituted by the casing 95 and a pair of cylindrical members, for example, a pair of metal pipes. As shown in FIGS. 5 and 6, the main operation member 50 of the folding operation mechanism 40 is rotatably attached to the casing 95 via a support shaft member 96 provided in the casing 95. The main operation member 50 is inserted into the support shaft member 96, and is connected to the casing 95 so as to be rotatable about the support shaft member 96. The lever portion 50a extends from the main operation member 50b. And have. The lever portion 50 a extends from the casing 95 via the first opening 95 a of the casing 95 so that the main operation member 50 can be operated from the outside of the casing 95.
　一方、図７および図８に示すように、ハンドル３６の主部３７の下方部分に、言い換えると、背面押し位置にあるハンドル３６のうちのロック部材３０と幅方向に対面する部分に、支持部材９１が設けられている。支持部材９１は、ハンドル３６の主部３７の内部に固定されている。支持部材９１には、主部３７の長手方向に延びる支持長穴９１ａが設けられている。図７および図８に示すように、解除部材４１は、この支持長穴９１ａ内に配置され、支持長穴９１ａ内を移動可能となっている。すなわち、解除部材４１は、支持長穴９１ａに誘導されて、ハンドル３６の主部３７の長手方向に沿って、主部３７および支持部材９１に対して摺動可能となっている。 On the other hand, as shown in FIGS. 7 and 8, a support member is provided at a lower portion of the main portion 37 of the handle 36, in other words, at a portion facing the lock member 30 in the width direction of the handle 36 in the back pushing position. 91 is provided. The support member 91 is fixed inside the main portion 37 of the handle 36. The support member 91 is provided with a support long hole 91 a extending in the longitudinal direction of the main portion 37. As shown in FIGS. 7 and 8, the release member 41 is disposed in the support slot 91a and is movable in the support slot 91a. That is, the release member 41 is guided by the support long hole 91 a and is slidable with respect to the main portion 37 and the support member 91 along the longitudinal direction of the main portion 37 of the handle 36.
　図４、図７および図８に示すように、解除部材４１は、ハンドル３６の主部３７内において、支持部材９１の支持長穴９１ａに配置された本体部（解除部材本体部）４１ａと、ベビーカー１０の幅方向に本体部４１ａから突出した突出部（解除部材突出部、突出ピン）４１ｂと、を有している。図７および図８に示すように、支持部材９１と本体部４１ａとの間には、例えば圧縮バネ等からなる主付勢部材４９が設けられている。この主付勢部材４９によって、解除部材４１は、ハンドル３６の主部３７に沿って下方に、すなわち、主操作部材５０から離間する向きに付勢されている。 As shown in FIGS. 4, 7, and 8, the release member 41 includes a main body portion (release member main body portion) 41 a disposed in the support long hole 91 a of the support member 91 within the main portion 37 of the handle 36. The baby stroller 10 has a protruding portion (release member protruding portion, protruding pin) 41 b protruding from the main body portion 41 a in the width direction of the stroller 10. As shown in FIGS. 7 and 8, a main urging member 49 made of, for example, a compression spring is provided between the support member 91 and the main body 41a. The main biasing member 49 biases the release member 41 downward along the main portion 37 of the handle 36, that is, in a direction away from the main operation member 50.
　突出部４１ｂは、主部３７に形成された第１長穴３７ａを貫通し、ハンドル３６の外に延び出ている。第１長穴３７ａは、突出部４１ｂの移動方向に沿って、すなわち、主部３７の長手方向に沿って延びている。図４に示すように、突出部４１ｂは、ベビーカー本体１１の第１リンク材２６上に設けられたロック部材３０の受け片３１に下方から当接することができる。そして、折り畳み操作機構４０が操作されて、解除部材４１が主部３７に沿って上方に摺動すると、突出部４１ｂが受け片３１に下方から当接して、ロック部材３０が第１リンク材２６に沿って上方に摺動するようになる。ロック部材３０が上方に移動すると、ロック部材３０と第３リンク材３４との係合が解除され、ベビーカー本体１１の折り畳み動作が可能となる。すなわち、ここで説明した例において、主付勢部材４９によって付勢されるべき位置が、ベビーカー本体１１の折り畳み動作が規制されるようになる解除部材４１の規制位置である。一方、主付勢部材４９の付勢力に抗して主部３７に沿って上方に移動した位置が、ベビーカー本体１１の折り畳み動作を可能にする解除部材４１の解除位置となる。 The protruding portion 41 b passes through the first long hole 37 a formed in the main portion 37 and extends outside the handle 36. The first elongated hole 37 a extends along the moving direction of the protruding portion 41 b, that is, along the longitudinal direction of the main portion 37. As shown in FIG. 4, the protruding portion 41 b can come into contact with the receiving piece 31 of the lock member 30 provided on the first link member 26 of the stroller body 11 from below. When the folding operation mechanism 40 is operated and the release member 41 slides upward along the main portion 37, the protruding portion 41 b comes into contact with the receiving piece 31 from below, and the lock member 30 is moved to the first link member 26. And slide upward. When the lock member 30 moves upward, the engagement between the lock member 30 and the third link member 34 is released, and the stroller body 11 can be folded. That is, in the example described here, the position to be urged by the main urging member 49 is the restriction position of the release member 41 where the folding operation of the stroller body 11 is restricted. On the other hand, the position moved upward along the main portion 37 against the urging force of the main urging member 49 becomes the release position of the release member 41 that enables the stroller body 11 to be folded.
　次に、折り畳み操作機構４０の伝達手段４３について説明する。図示する例では、ロック部材３０が、左右の第１リンク材２６にそれぞれ設けられ、解除部材４１も、一対のロック部材３０に対応して、ハンドル３６の左右の主部３７にそれぞれ設けられている。このため、伝達手段４３も、一対のロック部材３０に対応して、一対設けられている。そして、各伝達手段４３は、ケーシング９５に設けられた主操作部材５０と、主部３７に設けられた解除部材４１と、の間を延びている。すなわち、各伝達手段４３は、ケーシング９５にそれぞれ接続され且つケーシング９５とともにハンドル３６を構成する筒状部材内を、延びている。 Next, the transmission means 43 of the folding operation mechanism 40 will be described. In the illustrated example, the lock members 30 are provided on the left and right first link members 26, respectively, and the release members 41 are also provided on the left and right main portions 37 of the handle 36 corresponding to the pair of lock members 30.

In the illustrated example, the connection member 47 has a linear member 47a made of a flexible wire or the like connected at both ends to the rotating portion 50b and the release member 41, and a cylindrical shape through which the linear member 47a is slidably inserted. Member 47b. Both ends of the cylindrical member 47b are fixed to the handle 36 at positions near the rotating portion 50b and the release member 41.
　図５および図６に示すように、線状部材４５ａ，４７ａの一端が固定された主操作部材５０の回動部５０ｂは、円板状の外輪郭を有している。円板状からなる回動部５０ｂの外周面には、線状部材４５ａ，４７ａを巻き取り可能な誘導溝５２が形成されている。そして、図５に示された主操作部材５０の位置から、図６に示された主操作部材５０の位置まで、レバー部５０ａを操作して回動部５０ｂを回動させると、線状部材４５ａ，４７ａが、筒状部材４５ｂ，４７ｂからケーシング９５内に引き出され、回動部５０ｂの誘導溝５２に巻き取られるようになる。 As shown in FIGS. 5 and 6, the rotating portion 50b of the main operation member 50 to which one end of the linear members 45a and 47a is fixed has a disk-like outer contour. A guide groove 52 capable of winding the linear members 45a and 47a is formed on the outer peripheral surface of the rotating portion 50b having a disk shape. When the lever portion 50a is operated to rotate the rotating portion 50b from the position of the main operating member 50 shown in FIG. 5 to the position of the main operating member 50 shown in FIG. 45a and 47a are pulled out from the cylindrical members 45b and 47b into the casing 95 and wound around the guide groove 52 of the rotating portion 50b.
　このとき、右側の伝達手段４３（図５および図６における図面の左側の伝達手段）においては、線状部材４７ａの筒状部材４７ｂに対する相対移動により、解除部材４１が、主付勢部材４９に抗して規制位置から解除位置まで移動する。左側の伝達手段４３（図５および図６における図面の右側の伝達手段）においては、第１線状部材４５ａの第１筒状部材４５ｂに対する相対移動により、保持解除部材４４を介して、第２線状部材４６ａが第２筒状部材４６ｂから第１接続部材４５の側に引き出される。結果として、第２線状部材４６ａの第２筒状部材４６ｂに対する相対移動により、解除部材４１が、主付勢部材４９に抗して規制位置（図７の位置）から解除位置（図８の位置）まで移動する。 At this time, in the right transmission means 43 (left transmission means in FIGS. 5 and 6), the release member 41 is moved to the main biasing member 49 by the relative movement of the linear member 47a with respect to the cylindrical member 47b. Move from the restriction position to the release position. In the transmission means 43 on the left side (transmission means on the right side of the drawings in FIGS. 5 and 6), the second linear member 45a is moved relative to the first tubular member 45b by the second release via the holding release member 44. The linear member 46a is pulled out from the second tubular member 46b to the first connecting member 45 side. As a result, due to the relative movement of the second linear member 46a with respect to the second tubular member 46b, the release member 41 resists the main biasing member 49 from the restriction position (position in FIG. 7) to the release position (in FIG. 8). To position).
　すなわち、折り畳み操作機構４０によれば、主操作部材５０を操作することにより、一対の解除部材４１をそれぞれ規制位置から解除位置へ移動させることができる。したがって、主操作部材５０を操作することにより、一対のロック部材３０を移動させて、各ロック部材３０と対応する側の第３リンク材３４との係合を解除し、ベビーカー本体１１を折り畳み可能な状態とすることができる。一方、主操作部材５０に外力が加えられていない状態においては、主付勢部材４９からの付勢力によって、解除部材４１が解除位置から規制位置まで移動する。これにともなって、各ロック部材３０が対応する側の第３リンク材３４と係合し、ベビーカー本体１１の折り畳み動作が規制される。なお、保持解除部材４４については、第２操作規制機構６０とともに後に詳述する。 That is, according to the folding operation mechanism 40, by operating the main operation member 50, the pair of release members 41 can be moved from the restriction position to the release position, respectively. Therefore, by operating the main operation member 50, the pair of lock members 30 can be moved to disengage the lock members 30 from the corresponding third link members 34, and the stroller body 11 can be folded. It can be in a state. On the other hand, in a state where no external force is applied to the main operation member 50, the release member 41 is moved from the release position to the restriction position by the biasing force from the main biasing member 49. Accordingly, each lock member 30 is engaged with the corresponding third link member 34, and the folding operation of the stroller body 11 is restricted. The holding release member 44 will be described in detail later together with the second operation restriction mechanism 60.
　次に、第１操作規制機構５５について説明する。上述したように、第１操作規制機構５５は、操作されることによって、主操作部材５０を用いた解除部材４１の操作を規制する第１ロック位置（図５の位置）から、主操作部材５０を用いた解除部材４１の操作を可能にする第１非ロック位置（図６の位置）まで移動可能な第１規制解除操作部材５６を有している。 Next, the first operation restriction mechanism 55 will be described. As described above, the first operation restriction mechanism 55 is operated to move the main operation member 50 from the first lock position (position in FIG. 5) that restricts the operation of the release member 41 using the main operation member 50. It has the 1st regulation cancellation | release operation member 56 which can move to the 1st non-locking position (position of FIG. 6) which enables operation of the cancellation | release member 41 using.
　図５および図６に示すように、第１規制解除操作部材５６は、折り畳み操作機構４０の主操作部材５０の近傍に配置されている。このため、第１規制解除操作部材５６は、第１ロック位置において、主操作部材５０と直接接触し、第１規制解除操作部材５６の動作を規制するようになっている。すなわち、第１操作規制機構５５は、折り畳み操作機構４０の主操作部材５０と係合して主操作部材５０の動作を規制し、主操作部材５０を用いた解除部材４１の操作を規制することができる。 As shown in FIGS. 5 and 6, the first restriction release operation member 56 is disposed in the vicinity of the main operation member 50 of the folding operation mechanism 40. Therefore, the first restriction release operation member 56 is in direct contact with the main operation member 50 at the first lock position, and restricts the operation of the first restriction release operation member 56. That is, the first operation restriction mechanism 55 is engaged with the main operation member 50 of the folding operation mechanism 40 to restrict the operation of the main operation member 50 and restrict the operation of the release member 41 using the main operation member 50. Can do.
　図５および図６に示すように、第１規制解除操作部材５６は、主操作部材５０と同様にケーシング９５内に配置されている。図５および図６に示すように、ケーシング９５内には、第１規制解除操作部材５６と係合する誘導溝９７が形成されている。第１規制解除操作部材５６は、誘導溝９７に誘導されて、ケーシング９５に対して一定の方向のみに摺動可能に支持されている。第１規制解除操作部材５６は、ケーシング９５の第２開口９５ｂ内に延び入った操作凸部５６ａを有している。この操作凸部５６ａを介して、ケーシング９５の外部から第１規制解除操作部材５６を操作し得るようになっている。 As shown in FIGS. 5 and 6, the first restriction release operation member 56 is disposed in the casing 95 in the same manner as the main operation member 50. As shown in FIGS. 5 and 6, a guide groove 97 that engages with the first restriction release operation member 56 is formed in the casing 95. The first deregulation operation member 56 is guided by the guide groove 97 and supported so as to be slidable only in a certain direction with respect to the casing 95. The first restriction release operation member 56 has an operation convex portion 56 a extending into the second opening 95 b of the casing 95. The first restriction release operation member 56 can be operated from the outside of the casing 95 via the operation convex portion 56a.
　図５および図６に示すように、第１規制解除操作部材５６は、板状の部材として形成されている。第１規制解除操作部材５６には、板状の本体部からケーシング９５の内方に向けて延び出した操作規制係合部（係合突出部）５７が設けられている。この操作規制係合部５７は、主操作部材５０の回動部５０ｂに形成された切欠部（操作規制溝）５１と係合し得るようになっている。 As shown in FIGS. 5 and 6, the first restriction release operation member 56 is formed as a plate-like member. The first restriction release operation member 56 is provided with an operation restriction engagement part (engagement protrusion part) 57 extending from the plate-like main body part toward the inside of the casing 95. The operation restriction engaging portion 57 can be engaged with a notch (operation restriction groove) 51 formed in the rotating portion 50 b of the main operation member 50.
　図５および図６に示すように、ケーシング９５と、第１規制解除操作部材５６との間には、例えば引っ張りバネからなる第１規制付勢部材５９が設けられている。この第１規制付勢部材５９は、操作規制係合部５７が主操作部材５０から離間する第１非ロック位置（図６の位置）から、操作規制係合部５７が主操作部材５０の切欠部５１と係合して主操作部材５０の動作を規制する第１ロック位置（図５の位置）に向けて、第１規制解除操作部材５６を付勢している。すなわち、第１規制解除操作部材５６および主操作部材５０に操作力が加えられていない場合、第１規制解除操作部材５６は、第１規制付勢部材５９によって、第１非ロック位置から付勢されて第１ロック位置へ戻される。 As shown in FIGS. 5 and 6, a first restriction urging member 59 made of, for example, a tension spring is provided between the casing 95 and the first restriction release operation member 56. The first restriction urging member 59 is configured such that the operation restriction engagement portion 57 is notched to the main operation member 50 from the first unlocked position (the position in FIG. 6) where the operation restriction engagement portion 57 is separated from the main operation member 50. The first restriction release operation member 56 is biased toward a first lock position (position in FIG. 5) that engages with the portion 51 and restricts the operation of the main operation member 50. That is, when no operating force is applied to the first restriction release operation member 56 and the main operation member 50, the first restriction release operation member 56 is urged from the first unlock position by the first restriction urging member 59. And returned to the first lock position.
　このような構成によれば、第１規制解除操作部材５６が第１非ロック位置に配置されて主操作部材５０の動作が開始されると、第１規制解除操作部材５６から手を離したとしても、第１規制解除操作部材５６は動作中の主操作部材５０の回動部５０ｂの外周面に当接するようになり、第１ロック位置への復帰が阻まれる。その一方で、主操作部材５０の操作が終了して、主付勢部材４９からの付勢力によって解除部材４１が規制位置に戻ると、第１規制付勢部材５９からの付勢力によって、第１規制解除操作部材５６は自動的に第１ロック位置に復帰するようになる。すなわち、ベビーカー１０を折り畳もうとする保護者は、操作部材５０の操作が開始されるまでの間だけ、第１規制付勢部材５９に抗して第１規制解除操作部材５６を第１非ロック位置へ移動させておけばよい。そして、ベビーカー１０の展開状態においては、第１規制解除操作部材５６が自動的に第１ロック位置に復帰し、意図しないベビーカー１０（ベビーカー本体１１）の折り畳み操作を効果的に防止することができる。 According to such a configuration, when the first restriction release operation member 56 is disposed at the first unlocked position and the operation of the main operation member 50 is started, the hand is released from the first restriction release operation member 56. In addition, the first restriction release operation member 56 comes into contact with the outer peripheral surface of the rotating portion 50b of the main operation member 50 in operation, and the return to the first lock position is prevented. On the other hand, when the operation of the main operation member 50 is finished and the release member 41 returns to the restriction position by the urging force from the main urging member 49, the first urging force from the first restriction urging member 59 causes the first The restriction release operation member 56 automatically returns to the first lock position. That is, the guardian who wants to fold the stroller 10 moves the first restriction releasing operation member 56 against the first restriction biasing member 59 until the operation of the operation member 50 is started. Move it to the locked position. In the unfolded state of the stroller 10, the first restriction release operating member 56 automatically returns to the first lock position, and an unintended folding operation of the stroller 10 (stroller body 11) can be effectively prevented. .
　なお、図５に示すように、第１非ロック位置において、切欠部５１に当接して主操作部材５０の動作を規制するようになる操作規制係合部５７の当接面５７ａは、第１規制解除操作部材５６のケーシング９５に対する摺動方向と平行になっている。したがって、第１規制解除操作部材５６が第１ロック位置に位置する際に、主操作部材５０を操作しようとする力が加えられたとしても、当接面５７ａを介して第１規制解除操作部材５６に伝達される力は、第１規制解除操作部材５６を摺動させる方向には作用しない、或いは、少なくとも第１規制解除操作部材５６を摺動させる大きな力とはなり得ない。したがって、誤操作等によって意図せずベビーカー本体１１の折り畳み動作が始まってしまうことをより効果的に防止することができる。 As shown in FIG. 5, in the first unlocked position, the contact surface 57a of the operation restriction engagement portion 57 that comes into contact with the notch 51 and restricts the operation of the main operation member 50 is the first contact position 57a. The restriction release operation member 56 is parallel to the sliding direction with respect to the casing 95. Therefore, even when a force for operating the main operation member 50 is applied when the first restriction release operation member 56 is located at the first lock position, the first restriction release operation member via the contact surface 57a. The force transmitted to 56 does not act in the direction in which the first restriction release operation member 56 is slid, or at least cannot be a large force to slide the first restriction release operation member 56. Therefore, it can prevent more effectively that the folding operation | movement of the stroller main body 11 starts unintentionally by mistaken operation etc.
　次に、第２操作規制機構６０について説明する。上述したように、第２操作規制機構６０は、操作されることによって、主操作部材５０を用いた解除部材４１の操作を規制する第２ロック位置（図７の位置）から、主操作部材５０を用いた解除部材４１の操作を可能にする第２非ロック位置（図８～図１０の位置）まで移動可能な第２規制解除操作部材６１を有している。また、この第２規制解除操作部材６１は、操作されて第２ロック位置から第２非ロック位置まで移動すると第２非ロック位置に保持されるようになっている。第２規制解除操作部材６１の第２非ロック位置への保持は、当該第２規制解除操作部材６１が第２非ロック位置に位置するとともに第１規制解除操作部材５６が第１非ロック位置に位置した状態で主操作部材５０が操作されることによって、解除されるようになっている。 Next, the second operation restriction mechanism 60 will be described. As described above, the second operation restricting mechanism 60 is operated to move the main operation member 50 from the second lock position (the position in FIG. 7) that restricts the operation of the release member 41 using the main operation member 50. The second restriction release operating member 61 is movable to a second unlocked position (position shown in FIGS. 8 to 10) that enables the release member 41 to be operated. Further, when the second restriction release operation member 61 is operated and moved from the second lock position to the second unlock position, the second restriction release operation member 61 is held at the second unlock position. The second restriction release operation member 61 is held at the second unlock position when the second restriction release operation member 61 is located at the second unlock position and the first restriction release operation member 56 is placed at the first unlock position. When the main operation member 50 is operated in the positioned state, it is released.
　図７および図８に示すように、第２操作規制機構６０は、第２規制解除操作部材６１に接続された操作規制部材７０を有している。図７に示すように、第２規制解除操作部材６１が第２ロック位置に位置する際に、解除部材４１の規制位置から解除位置までの移動経路内に、操作規制部材７０の少なくとも一部分が入り込むようになっている。すなわち、第２規制解除操作部材６１が第２ロック位置に位置すると、解除部材４１が、規制位置から解除位置まで移動することが不可能となり、ベビーカー１０（ベビーカー本体１１）の折り畳み動作を実施することができない。すなわち、第２操作規制機構第６０の他方は、解除部材４１と係合して解除部材４１の動作を規制し、主操作部材５０を用いた解除部材４１の操作を規制することができる。 7 and 8, the second operation restriction mechanism 60 has an operation restriction member 70 connected to the second restriction release operation member 61. As shown in FIG. 7, when the second restriction release operation member 61 is positioned at the second lock position, at least a part of the operation restriction member 70 enters the movement path from the restriction position of the release member 41 to the release position. It is like that. That is, when the second restriction release operation member 61 is located at the second lock position, the release member 41 cannot move from the restriction position to the release position, and the stroller 10 (stroller body 11) is folded. I can't. That is, the other of the second operation restriction mechanisms 60 can engage with the release member 41 to restrict the operation of the release member 41 and restrict the operation of the release member 41 using the main operation member 50.
　図示された例において、操作規制部材７０は、揺動軸部材７１を介して支持部材９１に揺動可能に連結されている。操作規制部材７０は、第２規制解除操作部材６１が第２ロック位置に位置する際に配置される係合位置（図７の位置）と、第２規制解除操作部材６１が第２非ロック位置に位置する際に配置される非係合位置（図８の位置）と、の間を揺動することによって移動可能となっている。 In the illustrated example, the operation restricting member 70 is swingably connected to the support member 91 via the swing shaft member 71. The operation restriction member 70 includes an engagement position (a position in FIG. 7) that is disposed when the second restriction release operation member 61 is located at the second lock position, and the second restriction release operation member 61 is in the second unlock position. It is possible to move by swinging between a non-engagement position (position in FIG. 8) that is disposed when it is positioned in the position.
　操作規制部材７０は、係合位置に位置する際に解除部材４１と接触するようになる接触部７０ａを有している。図示された例では、操作規制部材７０の揺動軸線７１ａと平行な方向から観察した場合、つまり、図７および図８において、操作規制部材７０の接触部７０ａと操作規制部材７０の揺動軸線７１ａとを結ぶ方向ｄａが、図７に示された操作規制部材７０が係合位置に配置されている場合において、解除部材４１の規制位置から解除位置に向けた移動方向（つまり、主部３７の長手方向）と平行になっている、或いは、解除部材４１の規制位置から解除位置に向けた移動方向に対して操作規制部材７０が非係合位置に配置されている場合（図８の場合）とは逆側に傾斜している。このような構成によれば、操作規制部材７０が係合位置に配置されている際に、主操作部材５０を操作しようとする力が加えられたとしても、解除部材４１から接触部７０ａを介して操作規制部材７０に伝達される力は、操作規制部材７０を揺動させる方向には作用しない、或いは、少なくとも操作規制部材７０を揺動させる大きな力となり得ない。このため、誤操作等によって意図せずベビーカー本体１１の折り畳み動作が始まってしまうことをより効果的に防止することができる。 The operation restricting member 70 has a contact portion 70a that comes into contact with the release member 41 when positioned at the engagement position. In the illustrated example, when observed from a direction parallel to the swing axis 71a of the operation restricting member 70, that is, in FIGS. 7 and 8, the contact portion 70a of the operation restricting member 70 and the swing axis of the operation restricting member 70. The direction da connecting to 71a is the moving direction from the restricting position of the releasing member 41 to the releasing position (that is, the main portion 37) when the operation restricting member 70 shown in FIG. Or the operation restricting member 70 is disposed at the non-engagement position with respect to the moving direction from the restricting position of the releasing member 41 toward the releasing position (in the case of FIG. 8). ) To the opposite side. According to such a configuration, even when a force for operating the main operation member 50 is applied when the operation restricting member 70 is disposed at the engagement position, the release member 41 can be connected via the contact portion 70a. Therefore, the force transmitted to the operation restricting member 70 does not act in the direction in which the operation restricting member 70 is swung, or at least cannot be a large force that causes the operation restricting member 70 to swing. For this reason, it can prevent more effectively that the folding operation | movement of the baby stroller main body 11 starts unintentionally by misoperation etc.
　図７および図８に示すように、第２規制解除操作部材６１は、ハンドル３６の主部３７に沿って当該ハンドル３６の長手方向に摺動可能に設けられている。第２規制解除操作部材６１は、一例として筒状に形成されており、主部３７が第２規制解除操作部材６１内を通過している。図７および図８に示すように、第２規制解除操作部材６１は、ハンドル３６の主部３７に形成された第１長穴３７ａを貫通する保持ピン６２を有している。第２長穴３７ｂは主部３７の長手方向に延びており、この第２長穴３７ｂと保持ピン６２とが係合することにより、ハンドル３６上における第２規制解除操作部材６１の摺動可能範囲が画定されている。 7 and 8, the second restriction release operation member 61 is provided to be slidable in the longitudinal direction of the handle 36 along the main portion 37 of the handle 36. The second restriction release operation member 61 is formed in a cylindrical shape as an example, and the main portion 37 passes through the second restriction release operation member 61. As shown in FIGS. 7 and 8, the second restriction release operation member 61 has a holding pin 62 that passes through the first long hole 37 a formed in the main portion 37 of the handle 36. The second elongate hole 37b extends in the longitudinal direction of the main portion 37, and the second elongate hole 37b and the holding pin 62 engage with each other so that the second restriction release operation member 61 can slide on the handle 36. A range is defined.
　第２規制解除操作部材６１は、主操作部材５０を用いた解除部材４１の操作が可能となる第２非ロック位置において、第２規制解除操作部材６１の摺動可能範囲のうちの上方に位置する。一方、第２規制解除操作部材６１は、主操作部材５０を用いた解除部材４１の操作が規制される第２ロック位置において、第２非ロック位置よりも下方に位置する。すなわち、第２規制解除操作部材６１は、重力により、第２非ロック位置から第２ロック位置に配置されやすくなる。したがって、第２操作規制機構６０がより有効に機能し、意図せずベビーカー本体１１の折り畳み動作が始まってしまうことをより効果的に防止することができる。 The second restriction release operation member 61 is positioned above the slidable range of the second restriction release operation member 61 in the second unlocked position where the release member 41 can be operated using the main operation member 50. To do. On the other hand, the second restriction release operation member 61 is positioned below the second unlock position at the second lock position where the operation of the release member 41 using the main operation member 50 is restricted. That is, the second restriction release operation member 61 is easily arranged from the second unlocked position to the second locked position due to gravity. Therefore, it can prevent more effectively that the 2nd operation control mechanism 60 functions more effectively, and the folding operation | movement of the stroller main body 11 starts unintentionally.
　第２規制解除操作部材６１の内面には、筒状からなる第２規制解除操作部材６１が外方に膨出することによって、長溝６１ｃが形成されている。長溝６１ｃは、第２ロック位置と第２非ロック位置とを結ぶ方向、すなわち、ハンドル３６の主部３７の長手方向に延びている。一方、ハンドル３６の主部３７からは、付勢受け突出片８６が外方に突出している。付勢受け突出片（突出片）８６は、長溝６１ｃ内に収容されている。なお、上述した保持ピン６２と第２長穴３７ｂとの係合に加え、付勢受け突出片８６と長溝６１ｃとの係合によって、第２規制解除操作部材６１のハンドル３６に対する摺動が案内され、これにより、第２規制解除操作部材６１の摺動を円滑にすることができる。 A long groove 61c is formed on the inner surface of the second restriction release operation member 61 by the tubular second restriction release operation member 61 bulging outward. The long groove 61c extends in the direction connecting the second lock position and the second non-lock position, that is, in the longitudinal direction of the main portion 37 of the handle 36. On the other hand, from the main part 37 of the handle 36, an urging receiving protruding piece 86 protrudes outward. The bias receiving protrusions (protrusion pieces) 86 are accommodated in the long grooves 61c. In addition to the engagement between the holding pin 62 and the second elongated hole 37b described above, the engagement of the bias receiving protrusion 86 and the elongated groove 61c guides the sliding of the second restriction release operating member 61 relative to the handle 36. Thus, the second restriction release operation member 61 can be smoothly slid.
　長溝６１ｃと突出片８６との間には、例えば圧縮バネからなる第２規制付勢部材８９が設けられている。この第２規制付勢部材８９は、図８に示された第２非ロック位置から図７に示された第２ロック位置に向けて第２規制解除操作部材６１を付勢している。すなわち、第２規制解除操作部材６１は、第２規制付勢部材８９からの付勢力によって、後述するようにして第２非ロック位置に保持されていない状態において、第２非ロック位置から付勢されて第１ロック位置へ戻される。このような構成では、第２規制解除操作部材６１を付勢するための機構が、ハンドル３６の外部に設けられているので、ハンドル３６の内部スペースを有効に利用することができる。例えば、ハンドル３６を必要以上に大きく又は太くすることなく、第２規制解除操作部材６１の第２非ロック位置への保持を解除する後述の機構をハンドル３６の内部に配置することができる。 Between the long groove 61c and the protruding piece 86, a second restriction urging member 89 made of, for example, a compression spring is provided. The second restriction urging member 89 urges the second restriction release operation member 61 from the second unlock position shown in FIG. 8 toward the second lock position shown in FIG. That is, the second restriction release operation member 61 is biased from the second unlocked position by a biasing force from the second restriction biasing member 89 in a state where it is not held at the second unlocked position as will be described later. And returned to the first lock position. In such a configuration, since the mechanism for biasing the second restriction release operation member 61 is provided outside the handle 36, the internal space of the handle 36 can be used effectively. For example, a mechanism to be described later for releasing the second restriction release operation member 61 from being held in the second unlocked position can be arranged inside the handle 36 without making the handle 36 larger or thicker than necessary.
　なお、図９および図１０に示すように、付勢受け突出片８６は、ハンドル３６の主部３７に形成された挿通孔（第２挿通孔３７ｄ）を介して、後述する主部３７の内部に固定されたケーシング８０に嵌め込まれて保持されている。 As shown in FIGS. 9 and 10, the urging receiving protrusion 86 is disposed inside the main portion 37 to be described later via an insertion hole (second insertion hole 37 d) formed in the main portion 37 of the handle 36. It is fitted and held in the casing 80 fixed to.
　図７および図８に示すように、ハンドル３６の主部３７からは、ハンドル３６内に没入可能に外方へ向けて突出した保持部材８５が設けられている。保持部材８５は、ハンドル３６の内部の設けられた保持付勢部材８８によって、外方に向けて付勢されている。一方、筒状に形成された第２規制解除操作部材６１には、保持部材８５を受ける凹部６１ａが形成されている。この凹部６１ａに、保持部材８５の先端が係合することによって、第２規制解除操作部材６１が第２ロック位置に保持される。図示された例において、凹部６１ａは、第２規制解除操作部材６１を貫通する貫通穴として形成されている。ただし、凹部６１ａは、底を有する有底の穴として形成されていてもよい。 As shown in FIGS. 7 and 8, a holding member 85 that protrudes outward from the main portion 37 of the handle 36 so as to be immersed in the handle 36 is provided. The holding member 85 is urged outward by a holding urging member 88 provided inside the handle 36. On the other hand, a concave portion 61a that receives the holding member 85 is formed in the second restriction release operation member 61 formed in a cylindrical shape. When the tip of the holding member 85 is engaged with the recess 61a, the second restriction release operation member 61 is held at the second lock position. In the illustrated example, the recess 61 a is formed as a through hole that penetrates the second restriction release operation member 61. However, the recess 61a may be formed as a bottomed hole having a bottom.
　また、図７および図８に示すように、第２規制解除操作部材６１は、凹部６１ａに隣接した位置に誘導部６１ｂを有している。誘導部６１ｂは、保持部材８５の先端に係合して、保持部材８５を凹部６１ａへ誘導する斜面を含んでいる。誘導部６１ｂは、第２規制解除操作部材６１が第２ロック位置から第２非ロック位置へ摺動する際に凹部６１ａの前方となる位置において、第２規制解除操作部材６１に設けられている。誘導部６１ｂは、凹部６１ａの上方において、外方に壁面が広がっていく拡径部として構成されている。このような誘導部６１ｂによれば、ハンドル３６の長手方向に直交する方向へ向けてハンドル３６から突出する保持部材８５を滑らか且つ安定して凹部６１ａへ誘導して、第２規制解除操作部材６１を第２非ロック位置に保持することができる。これにより、ベビーカーの折り畳み操作を容易且つ安定して実施することが可能となる。 Further, as shown in FIGS. 7 and 8, the second deregulation operation member 61 has a guiding portion 61b at a position adjacent to the recess 61a. The guide portion 61b includes a slope that engages with the tip of the holding member 85 and guides the holding member 85 to the recess 61a. The guide portion 61b is provided in the second restriction release operation member 61 at a position that is in front of the recess 61a when the second restriction release operation member 61 slides from the second lock position to the second unlock position. . The guiding portion 61b is configured as a diameter-expanding portion whose wall surface spreads outward above the concave portion 61a. According to such a guide portion 61b, the holding member 85 protruding from the handle 36 toward the direction orthogonal to the longitudinal direction of the handle 36 is smoothly and stably guided to the recess 61a, and the second restriction release operation member 61 is thus guided. Can be held in the second unlocked position. Thereby, the folding operation of the stroller can be performed easily and stably.
　以上のように、第２操作規制機構６０の第２規制解除操作部材６１と操作規制部材７０とは、離間して設けられている。このため第２操作規制機構６０は、第２規制解除操作部材６１の動作を操作規制部材７０に伝達する伝達手段として、接続部材６８を有している。接続部材６８は、第２規制解除操作部材１８と操作規制部材７０との間に設けられ、第２規制解除操作部材１８と操作規制部材７０とを連結している。接続部材６８は、金属線（針金）等の公知の手段によって構成され、一例として上述した伝達手段４３をなす柔軟なワイヤ等からなる線状部材と当該線状部材が摺動可能に挿通する筒状部材との組み合わせから構成され得る。 As described above, the second restriction release operation member 61 and the operation restriction member 70 of the second operation restriction mechanism 60 are provided apart from each other. For this reason, the second operation restriction mechanism 60 has a connection member 68 as a transmission means for transmitting the operation of the second restriction release operation member 61 to the operation restriction member 70. The connection member 68 is provided between the second restriction release operation member 18 and the operation restriction member 70, and connects the second restriction release operation member 18 and the operation restriction member 70. The connecting member 68 is constituted by a known means such as a metal wire (wire), and as an example, a linear member made of a flexible wire or the like forming the transmission means 43 described above and a cylinder through which the linear member is slidably inserted. It can be composed of a combination with a member.
　図示された例において、接続部材６８は、自立可能な棒状の部材、例えば自立可能な金属棒から構成されている。接続部材６８の一端は、輪状に曲げられ、当該輪状部を上述した保持ピン６２が挿通することにより、保持ピン６２を介して第２規制解除操作部材６１に支持されている。接続部材６８の他端は、折り曲げられて、操作規制部材７０の揺動軸線７１ａと平行な方向に延びて操作規制部材７０を貫通している。操作規制部材７０は、接続部材６８の他端を中心として、接続部材６８に対して回動可能となっている。このような接続部材６８によれば、極めて安価で単純な構成により、第２規制解除操作部材６１の動作を操作規制部材７０に伝達することができる。 In the illustrated example, the connecting member 68 is composed of a self-supporting rod-shaped member, for example, a self-supporting metal rod. One end of the connection member 68 is bent into a ring shape, and is supported by the second restriction release operation member 61 via the holding pin 62 when the holding pin 62 described above is inserted through the ring-shaped portion. The other end of the connection member 68 is bent, extends in a direction parallel to the swing axis 71 a of the operation restriction member 70, and penetrates the operation restriction member 70. The operation restricting member 70 is rotatable with respect to the connecting member 68 around the other end of the connecting member 68. According to such a connection member 68, the operation of the second restriction release operation member 61 can be transmitted to the operation restriction member 70 with a very inexpensive and simple configuration.
　ところで、図７および図８に示すように、ハンドル３６の主部３７内には、ケーシング８０が固定されている。ケーシング８０は、互いに嵌め合わされた第１部材８１および第２部材８２によって形成されている。図９および図１０に示すように、ケーシング８０の内部には、上述した保持解除部材４４が配置される収容スペース８３が形成されている。保持解除部材４４は、収容スペース８３内にて、ハンドル３６の主部３７の長手方向に沿って移動可能（摺動可能）となっている。上述したように、保持解除部材４４には、第１接続部材４５の第１線状部材４５ａの一端および第２接続部材４６の第２線状部材４６ａの一端が接続されている。このため、ケーシング８０には、第１線状部材４５ａが通過するための第１通過穴８３ａと、第２線状部材４５ｂが通過するための第２通過穴８３ｂと、が設けられている。 Incidentally, as shown in FIGS. 7 and 8, a casing 80 is fixed in the main portion 37 of the handle 36. The casing 80 is formed by a first member 81 and a second member 82 that are fitted together. As shown in FIGS. 9 and 10, a housing space 83 in which the above-described holding release member 44 is disposed is formed inside the casing 80. The holding release member 44 is movable (slidable) along the longitudinal direction of the main portion 37 of the handle 36 in the accommodation space 83. As described above, one end of the first linear member 45 a of the first connection member 45 and one end of the second linear member 46 a of the second connection member 46 are connected to the holding release member 44. For this reason, the casing 80 is provided with a first passage hole 83a through which the first linear member 45a passes and a second passage hole 83b through which the second linear member 45b passes.
　第２規制解除操作部材６１と係合して第２規制解除操作部材６１を第２非ロック位置に係止する保持部材８５は、ケーシング８０内に保持されている。そして、ケーシング８０内に配置された保持解除部材４４は、主操作部材５０が操作されて解除部材４１が規制位置から解除位置へ引き上げられる際に、保持部材８５と係合して保持部材８５をケーシング８０内に引き込むように動作する。このような構成によれば、極めて簡易な構成により、第２規制解除操作部材６１の第２非ロック位置への保持を、主操作部材５０の操作に連動して、自動的に解除することが可能となる。 The holding member 85 that engages with the second restriction release operation member 61 and locks the second restriction release operation member 61 in the second unlock position is held in the casing 80. The holding release member 44 disposed in the casing 80 engages with the holding member 85 and moves the holding member 85 when the main operation member 50 is operated and the release member 41 is pulled up from the restriction position to the release position. It operates so as to be drawn into the casing 80. According to such a configuration, the second restriction release operation member 61 can be automatically released from being held in the second unlocked position in conjunction with the operation of the main operation member 50 with a very simple configuration. It becomes possible.
　図９および図１０に示すように、保持部材８５は、拡径されたつば部８５ｂと、つば部８５ｂの両側に位置する突入部８５ａおよび支持部８５ｃと、を有している。突入部８５ａは、第１部材８１に設けられた挿通孔８１ａと、ハンドル３６の主部３７に設けられた挿通孔（第１挿通孔）３７ｃと、を摺動可能に挿通している。突入部８５ａは、挿通孔８１ａおよび挿通孔３７ｃに案内されながらケーシング８０に対して摺動することにより、ハンドル３６から外方に突出して第２規制解除操作部材６１の凹部６１ａに係合し得る。一方、第１部材８１の挿通孔８１ａと対面する位置において、第２部材８２に支持凹部８２ａが形成されている。支持凹部８２ａには、例えば圧縮バネからなる保持付勢部材８８が支持されている。保持付勢部材８８は、保持部材８５の突入部８５ａがハンドル３６から外方に突出するよう、保持部材８５を付勢している。その一方で、保持付勢部材８８の付勢力に抗して、保持部材８５をケーシング８０内に引き込むことにより、保持部材８５と第２規制解除操作部材６１の凹部６１ａとの係合を解除することができる。 As shown in FIGS. 9 and 10, the holding member 85 has a flange portion 85b having an enlarged diameter, and a protrusion 85a and a support portion 85c located on both sides of the flange portion 85b. The protrusion 85a is slidably inserted through an insertion hole 81a provided in the first member 81 and an insertion hole (first insertion hole) 37c provided in the main portion 37 of the handle 36. The protrusion 85a can slide outwardly from the handle 36 and engage with the recess 61a of the second restriction release operation member 61 by sliding with respect to the casing 80 while being guided by the insertion hole 81a and the insertion hole 37c. . On the other hand, a support recess 82 a is formed in the second member 82 at a position facing the insertion hole 81 a of the first member 81. A holding biasing member 88 made of, for example, a compression spring is supported on the support recess 82a. The holding biasing member 88 biases the holding member 85 so that the protrusion 85 a of the holding member 85 protrudes outward from the handle 36. On the other hand, by pulling the holding member 85 into the casing 80 against the urging force of the holding urging member 88, the engagement between the holding member 85 and the recess 61a of the second restriction release operation member 61 is released. be able to.
　図示された例において、保持部材８５の支持部８５ｃは、圧縮コイルバネからなる保持付勢部材８８内に挿入されて、保持付勢部材８８を支持している。また、保持付勢部材８８の端部は、保持部材８５のつば部８５ｂに当接している。このような態様によれば、保持部材８５の突入部８５ａが挿通孔８１ａおよび挿通孔３７ｃに案内されることとの組み合わせによって、保持部材８５のハンドル３６に対する動作を安定して円滑に行うことができる。 In the illustrated example, the support portion 85c of the holding member 85 is inserted into a holding biasing member 88 made of a compression coil spring to support the holding biasing member 88. Further, the end portion of the holding biasing member 88 is in contact with the flange portion 85 b of the holding member 85. According to such an aspect, the operation of the holding member 85 with respect to the handle 36 can be stably and smoothly performed by the combination of the protrusion 85a of the holding member 85 being guided by the insertion hole 81a and the insertion hole 37c. it can.
　図９および図１０に示すように、保持解除部材４４は、保持部材８５のつば部８５ｂと、第１部材８１の収容スペース８３を形成する底面と、の間に配置されている。保持解除部材４４の厚さは一定ではない。保持解除部材４４の厚みは、解除部材４１を規制位置から解除位置へ移動させる際の保持解除部材４４の移動において前方となる側において薄く、当該保持解除部材４４の移動において後方となる側において厚くなっている。これにより、ハンドル３６の主部３７の長手方向に移動する保持解除部材４４が保持部材８５と係合することによって、主部３７の長手方向と交差する方向、典型的には、主部３７の長手方向と直交する方向へ保持部材８５を移動させることが可能となる。 As shown in FIGS. 9 and 10, the holding release member 44 is disposed between the collar portion 85 b of the holding member 85 and the bottom surface forming the accommodation space 83 of the first member 81. The thickness of the holding release member 44 is not constant. The thickness of the holding release member 44 is thin on the front side in the movement of the holding release member 44 when the release member 41 is moved from the restriction position to the release position, and thick on the side on the rear side in the movement of the holding release member 44. It has become. As a result, the holding release member 44 that moves in the longitudinal direction of the main portion 37 of the handle 36 is engaged with the holding member 85, thereby crossing the longitudinal direction of the main portion 37, typically the main portion 37. The holding member 85 can be moved in a direction orthogonal to the longitudinal direction.
　より具体的には、図９および図１０に示すように、保持解除部材４４は、保持解除部材４４の移動方向および保持部材８５の移動方向の両方に対して傾斜した傾斜部４４ａを有している。主操作部材５０を操作することによって移動する保持解除部材４４の傾斜部４４ａは、保持部材８５のつば部８５ｂに当接する。傾斜部４４ａがつば部８５ｂに当接することによって、保持部材８５を第１部材８１の側から第２部材の側へ移動させ、当該保持部材８５をケーシング８０内に引き込むことが可能となる。これにより、保持部材８５と第２規制解除操作部材６１の凹部６１ａとの係合を解除することができる。 More specifically, as shown in FIGS. 9 and 10, the holding release member 44 has an inclined portion 44 a that is inclined with respect to both the moving direction of the holding releasing member 44 and the moving direction of the holding member 85. Yes. The inclined portion 44 a of the holding release member 44 that moves by operating the main operating member 50 contacts the collar portion 85 b of the holding member 85. When the inclined portion 44 a contacts the collar portion 85 b, the holding member 85 can be moved from the first member 81 side to the second member side, and the holding member 85 can be drawn into the casing 80. Thereby, engagement with the recessed part 61a of the holding member 85 and the 2nd regulation cancellation | release operation member 61 can be cancelled | released.
　なお、凹部６１ａとの係合を解除された第２規制解除操作部材６１は、第２規制付勢部材８９からの付勢力によって、第２非ロック位置から第２ロック位置へ向けて移動を開始する。すなわち、保持解除部材４４に設けられた傾斜部４４ａによれば、保持解除部材４４の動作を、方向を変換して、保持部材８５に安定して伝達することが可能となる。これにより、簡易な構成を用いながら、主操作部材５０の操作にともなって、第２規制解除操作部材６１の第２非ロック位置への保持を、より安定して且つより確実に自動的に解除することができる。 The second restriction release operation member 61 released from the engagement with the recess 61a starts to move from the second non-lock position to the second lock position by the urging force from the second restriction urging member 89. To do. That is, according to the inclined portion 44 a provided in the holding release member 44, the operation of the holding release member 44 can be stably transmitted to the holding member 85 by changing the direction. As a result, the holding of the second restriction release operation member 61 in the second non-locking position can be automatically released more stably and reliably with the operation of the main operation member 50 while using a simple configuration. can do.
　なお、図示された例では、保持解除部材４４の移動方向および保持部材８５の移動方向の両方に対して傾斜した傾斜部４４ａが、保持解除部材４４に設けられている。しかしながら、保持解除部材４４の移動方向および保持部材８５の移動方向の両方に対して傾斜した傾斜部が、保持解除部材４４および保持部材８５の両方、或いは、保持部材８５のみに設けられていても同様の作用効果を得ることができる。一例として、つば部８５ｂの保持解除部材４４に対面する面が傾斜部として形成されていてもよい。 In the illustrated example, the holding release member 44 is provided with an inclined portion 44 a that is inclined with respect to both the moving direction of the holding release member 44 and the moving direction of the holding member 85. However, even if both the holding release member 44 and the holding member 85 or the holding member 85 is provided with an inclined portion that is inclined with respect to both the moving direction of the holding release member 44 and the moving direction of the holding member 85. Similar effects can be obtained. As an example, the surface of the collar portion 85b facing the holding release member 44 may be formed as an inclined portion.
　また、図９および図１０に示すように、保持部材８５は、収容スペース８３を延びており、収容スペース８３内に配置された保持解除部材４４と係合するようになっている。図９～図１１に示すように、保持解除部材４４は、その厚み方向に延びる貫通孔４４ｂを形成されている。そして、保持部材８５の突入部８５ａは、保持解除部材４４の貫通孔４４ｂを貫通して延びている。このような構成によれば、異なる方向、とりわけ直交する方向に移動可能な保持解除部材４４および保持部材８５が互いの動作を案内し合うことになる。これにより、保持解除部材４４および保持部材８５が予定された方向に滑らかに動作することが可能となる。また、異なる方向に移動する保持解除部材４４および保持部材８５をケーシング８０内の狭い収容スペース８３内に配置することも可能となる。 Further, as shown in FIGS. 9 and 10, the holding member 85 extends through the storage space 83 and engages with the holding release member 44 disposed in the storage space 83. As shown in FIGS. 9 to 11, the holding release member 44 is formed with a through hole 44b extending in the thickness direction. The intrusion portion 85 a of the holding member 85 extends through the through hole 44 b of the holding release member 44. According to such a configuration, the holding release member 44 and the holding member 85 that are movable in different directions, in particular orthogonal directions, guide each other's operations. As a result, the holding release member 44 and the holding member 85 can operate smoothly in the planned direction. In addition, the holding release member 44 and the holding member 85 that move in different directions can be arranged in the narrow housing space 83 in the casing 80.
　とりわけ、図示された例では、図１１に示すように、貫通孔４４ｂの両側に傾斜部４４ａが形成されており、図１１に点線で外輪郭を示した保持部材８５のつば部８５ｂは、二箇所において、傾斜部４４ａと係合することができる。これにより、折り畳み操作機構４０の伝達手段４３の一部分をなす保持解除部材４４を用いることによって、より安定して、保持部材８５をハンドル３６内に引き込むことができる。 In particular, in the illustrated example, as shown in FIG. 11, inclined portions 44a are formed on both sides of the through hole 44b, and the collar portion 85b of the holding member 85 whose outer contour is indicated by a dotted line in FIG. It can engage with the inclined portion 44a at the location. Thereby, the holding member 85 can be pulled into the handle 36 more stably by using the holding release member 44 that forms a part of the transmission means 43 of the folding operation mechanism 40.
　なお、図示された例においては、保持解除部材４４に貫通孔４４ｂが形成され、当該貫通孔４４ｂを保持部材８５が挿通するようになっているが、これに限られず、保持部材８５に形成された貫通孔を保持解除部材４４が挿通するようにしてもよい。 In the illustrated example, a through hole 44b is formed in the holding release member 44, and the holding member 85 is inserted through the through hole 44b. However, the present invention is not limited to this, and the holding member 85 is formed in the holding member 85. The holding release member 44 may be inserted through the through hole.
　以上のような構成からなるベビーカー１０を折り畳む際の手順をまとめて説明すると次のようになる。 The procedure for folding the stroller 10 having the above-described configuration is described as follows.
　まず、第２操作規制機構６０の第２規制解除操作部材６１を、ハンドル３６の主部３７に沿って、第２ロック位置から第２非ロック位置まで摺動させる。この操作により、第２規制解除操作部材６１の凹部６１ａにハンドル３６から外方に突出する保持部材８５が嵌り込み、第２規制解除操作部材６１が第２非ロック位置に保持されるようになる。第２規制解除操作部材６１の第２ロック位置から第２非ロック位置への移動は、接続部材６８を介して、操作規制部材７０に伝達される。操作規制部材７０は、折り畳み操作機構４０の解除部材４１の規制位置から解除位置へ向けて移動を阻害する係合位置から、規制位置と解除位置との間の解除部材４１の移動経路外に配置される係合位置へ移動する。すなわち、第２規制解除操作部材６１の操作によって、第２操作規制機構６０による解除部材４１の移動の規制が解除される。 First, the second restriction release operation member 61 of the second operation restriction mechanism 60 is slid along the main portion 37 of the handle 36 from the second lock position to the second unlock position. By this operation, the holding member 85 protruding outward from the handle 36 is fitted into the recess 61a of the second restriction release operation member 61, and the second restriction release operation member 61 is held in the second unlocked position. . The movement of the second restriction release operation member 61 from the second lock position to the second unlock position is transmitted to the operation restriction member 70 through the connection member 68. The operation restriction member 70 is disposed outside the movement path of the release member 41 between the restriction position and the release position from the engagement position that inhibits the movement of the release member 41 of the folding operation mechanism 40 from the restriction position toward the release position. Move to the engaged position. That is, the movement of the release member 41 by the second operation restriction mechanism 60 is released by the operation of the second restriction release operation member 61.
　なお、第２規制解除操作部材６１の摺動方向は、ハンドル３６の長手方向に沿っている。一方、保持部材８５がハンドル３６の外方に向けて付勢される方向は、ハンドル３６の長手方向と交差する方向、典型的には、ハンドル３６の長手方向と直交する方向である。したがって、第２規制解除操作部材６１と保持部材８５との係合が意図せず解除されてしまうことを効果的に防止することができる。また、第２規制解除操作部材６１の第２非ロック位置へ向けた移動における凹部６１ａの前方となる位置には、保持部材８５の先端に係合して、これにより、保持部材８５をハンドル３６の内部に押し込み、当該保持部材８５の先端を凹部６１ａまで誘導する誘導部６１ｂが配置されている。このため、第２規制解除操作部材６１と保持部材８５との係合を安定して円滑に実現することもできる。 The sliding direction of the second restriction release operation member 61 is along the longitudinal direction of the handle 36. On the other hand, the direction in which the holding member 85 is urged toward the outside of the handle 36 is a direction that intersects the longitudinal direction of the handle 36, typically a direction that is orthogonal to the longitudinal direction of the handle 36. Therefore, it is possible to effectively prevent the engagement between the second restriction release operation member 61 and the holding member 85 from being unintentionally released. In addition, the front end of the recess 61a in the movement of the second restriction release operation member 61 toward the second unlocked position is engaged with the tip of the holding member 85, whereby the holding member 85 is engaged with the handle 36. A guiding portion 61b is disposed that guides the tip of the holding member 85 to the recess 61a. For this reason, engagement with the 2nd regulation cancellation | release operation member 61 and the holding member 85 can also be implement | achieved stably and smoothly.
　第２操作規制機構６０を操作した後に、次に、第１操作規制機構５５の第１規制解除操作部材５６を第１ロック位置から第１非ロック位置まで移動させる。第１操作規制機構５５の操作は、第１規制解除操作部材５６を単に摺動させるだけであり、且つ、第１規制解除操作部材５６は操作しやすいハンドル３６の中間部３８に設けられている。さらに、第２操作規制機構６０の第２規制解除操作部材６１は、保持部材８５によって第２非ロック位置に保持されているので、第２規制解除操作部材６１に手を掛けておく必要もない。したがって、第１操作規制機構５５の第１規制解除操作部材５６の操作を極めて容易に行って、第１規制解除操作部材５６の操作規制係合部５７と折り畳み操作機構４０の主操作部材５０との係合を解除することができる。これにより、第１操作規制機構５５による主操作部材５０の移動の規制が解除される。 After operating the second operation restriction mechanism 60, next, the first restriction release operation member 56 of the first operation restriction mechanism 55 is moved from the first lock position to the first unlock position. The operation of the first operation restriction mechanism 55 is merely to slide the first restriction release operation member 56, and the first restriction release operation member 56 is provided in the intermediate portion 38 of the handle 36 that is easy to operate. . Further, since the second restriction release operation member 61 of the second operation restriction mechanism 60 is held at the second unlocked position by the holding member 85, it is not necessary to put a hand on the second restriction release operation member 61. . Therefore, the first restriction release operation member 56 of the first operation restriction mechanism 55 is operated very easily, and the operation restriction engagement portion 57 of the first restriction release operation member 56 and the main operation member 50 of the folding operation mechanism 40 Can be released. Thereby, the restriction | limiting of the movement of the main operation member 50 by the 1st operation control mechanism 55 is cancelled | released.
　次に、第１規制解除操作部材５６を第１非ロック位置に維持した状態で、折り畳み操作機構４０の主操作部材５０を操作する。これにより、折り畳み操作機構４０の解除部材４１を規制位置から解除位置まで移動させることできる。この際、解除部材４１の動作に伴って、ベビーカー本体１１のロック部材３０が第３リンク材３４から引き離される。すなわち、ロック部材３０と第３リンク材３４との係合が解除され、ベビーカー本体１１を上述した手順で折り畳むことが可能となる。 Next, the main operation member 50 of the folding operation mechanism 40 is operated in a state where the first restriction release operation member 56 is maintained in the first unlocked position. Thereby, the release member 41 of the folding operation mechanism 40 can be moved from the restriction position to the release position. At this time, the lock member 30 of the stroller body 11 is pulled away from the third link member 34 with the operation of the release member 41. That is, the engagement between the lock member 30 and the third link member 34 is released, and the stroller body 11 can be folded according to the procedure described above.
　折り畳み操作機構４０の主操作部材５０は、第１規制解除操作部材５６と同様に、操作しやすいハンドル３６の中間部３８に設けられている。しかも、第１規制解除操作部材５６は、主操作部材５０に直接係合することができる程、主操作部材５０の近傍に配置されている。したがって、第１規制解除操作部材５６を第１非ロック位置に維持しながらも、容易に主操作部材５０を操作することもできる。典型的には、第１規制解除操作部材５６と主操作部材５０とを同じ手で操作することも可能である。すなわち、一方の手で乳幼児を抱きながら、他方の手を用いて、ベビーカー１０の折り畳みを行うことも可能となる。 The main operation member 50 of the folding operation mechanism 40 is provided at an intermediate portion 38 of the handle 36 that is easy to operate, like the first restriction release operation member 56. In addition, the first restriction release operation member 56 is disposed in the vicinity of the main operation member 50 such that it can be directly engaged with the main operation member 50. Therefore, it is possible to easily operate the main operation member 50 while maintaining the first restriction release operation member 56 in the first unlocked position. Typically, the first restriction release operating member 56 and the main operating member 50 can be operated with the same hand. That is, the baby stroller 10 can be folded using the other hand while holding the infant with one hand.
　また、主操作部材５０を操作して解除部材４１を移動させると、主操作部材５０の動作を解除部材４１に伝達する伝達手段４３が、第２規制解除操作部材６１と係合している保持部材８５をハンドル３６の内部に引き込む。これにより、第２規制解除操作部材６１は、第２規制付勢部材８９からの付勢力によって、第２非ロック位置から第２ロック位置へ向けた移動を開始する。すなわち、第２規制解除操作部材６１が第２非ロック位置に位置するとともに第１規制解除操作部材５６が第１非ロック位置に位置する状態で主操作部材５０が操作されると、第２規制解除操作部材６１は、第２非ロック位置への保持を自動的に解除される。したがって、ベビーカー１０の展開状態においては、第２規制解除操作部材６１が自動的に第２ロック位置に復帰し、意図しないベビーカー１０（ベビーカー本体１１）の折り畳み動作を効果的に防止することができる。 Further, when the release member 41 is moved by operating the main operation member 50, the transmission unit 43 that transmits the operation of the main operation member 50 to the release member 41 is engaged with the second restriction release operation member 61. The member 85 is pulled into the handle 36. As a result, the second restriction release operation member 61 starts moving from the second unlocked position to the second locked position by the biasing force from the second restriction biasing member 89. That is, when the main operation member 50 is operated in a state where the second restriction release operation member 61 is located at the second unlock position and the first restriction release operation member 56 is located at the first unlock position, the second restriction release member 61 is operated. The release operation member 61 is automatically released from being held in the second unlocked position. Therefore, in the unfolded state of the stroller 10, the second restriction release operation member 61 automatically returns to the second lock position, and an unintended folding operation of the stroller 10 (stroller body 11) can be effectively prevented. .
　以上のように本実施の形態によれば、ベビーカー１０は、折り畳み可能なベビーカー本体１１と、ベビーカー本体１１を展開状態に保持するロック部材３０を遠隔操作する折り畳み操作機構４０と、折り畳み操作機構４０の操作を規制する第１操作規制機構５５および第２操作規制機構６０と、を有している。すなわち、第１操作規制機構５５および第２操作規制機構６０の両方を解除しなければ、折り畳み操作機構４０を開始することができない。したがって、意図せずにベビーカー本体１１の折り畳み動作が始まってしまうことを効果的に防止することができる。 As described above, according to the present embodiment, the stroller 10 includes the foldable stroller body 11, the folding operation mechanism 40 that remotely operates the lock member 30 that holds the stroller body 11 in the unfolded state, and the folding operation mechanism 40. A first operation restricting mechanism 55 and a second operation restricting mechanism 60 for restricting the operation. That is, the folding operation mechanism 40 cannot be started unless both the first operation restriction mechanism 55 and the second operation restriction mechanism 60 are released. Therefore, it is possible to effectively prevent the folding operation of the stroller body 11 from starting unintentionally.
　そして、本実施の形態によれば、第２規制解除操作部材６１は、操作されて第２ロック位置から第２非ロック位置まで移動すると第２非ロック位置に保持され、且つ、当該第２規制解除操作部材６１が第２非ロック位置に位置するとともに第１規制解除操作部材５６が第１非ロック位置に位置する状態で主操作部材５０が操作されると、第２非ロック位置への保持を自動的に解除される。このようなベビーカー１０によれば、第２操作規制機構６０の第２規制解除操作部材６１を一度操作しさえすれば、第２規制解除操作部材６１が第２非ロック位置に保持される。したがって、第２規制解除操作部材６１から手を離して、次に、第１規制解除操作部材５６および主操作部５０材を操作し、ベビーカー本体１１を折り畳むことができる。すなわち、主操作部材５０、第１規制解除操作部材５６および第２規制解除操作部材６１の三つを同時に操作する必要がないので、ベビーカー本体１１の折り畳み操作を容易に実行することが可能となる。また、第１規制解除操作部材５６および第２規制解除操作部材６１がそれぞれ非ロック位置に位置した状態で主操作部材５０が操作されると、第２規制解除操作部材６１の第２非ロック位置への保持が自動的に解除される。このため、その後においては、例えばいったん折り畳まれたべビーカー本体１１が再度展開された際には、第２操作規制解除機構６０が有効に機能して、誤操作等によって意図せずベビーカー本体１１の折り畳み動作が始まってしまうことを効果的に防止することができる。すなわち、本実施の形態のベビーカー１０によれば、ベビーカー１０の折り畳み動作が意図せず開始されることを効果的に抑制することができ、その一方で、意図して折り畳もうとした際にベビーカーを容易な操作によって折り畳むことができる。 According to the present embodiment, when the second restriction release operation member 61 is operated and moved from the second lock position to the second unlock position, the second restriction release operation member 61 is held at the second unlock position and the second restriction release member 61 is operated. When the main operation member 50 is operated in a state where the release operation member 61 is located at the second unlock position and the first restriction release operation member 56 is located at the first unlock position, the release operation member 61 is held at the second unlock position. Is automatically canceled. According to such a stroller 10, once the second restriction release operation member 61 of the second operation restriction mechanism 60 is operated once, the second restriction release operation member 61 is held in the second unlocked position. Therefore, the stroller body 11 can be folded by releasing the second restriction release operation member 61 and then operating the first restriction release operation member 56 and the main operation portion 50 material. That is, since it is not necessary to operate the main operation member 50, the first restriction release operation member 56, and the second restriction release operation member 61 at the same time, the stroller body 11 can be easily folded. . In addition, when the main operation member 50 is operated in a state where the first restriction release operation member 56 and the second restriction release operation member 61 are respectively positioned at the unlocked position, the second unlocking position of the second restriction release operation member 61. Is automatically released. Therefore, after that, for example, when the beaker body 11 once folded is re-deployed, the second operation restriction release mechanism 60 functions effectively, and the stroller body 11 is unintentionally folded due to an erroneous operation or the like. Can be effectively prevented from starting. That is, according to the stroller 10 of the present embodiment, the folding operation of the stroller 10 can be effectively prevented from being started unintentionally, and on the other hand, when it is intended to be folded. The stroller can be folded by an easy operation.
　また、本実施の形態によれば、第１操作規制機構５５および第２操作規制機構６０の一方が、主操作部材５０と係合して主操作部材５０の動作を規制し、主操作部材８０を用いた解除部材４１の操作が規制され、第１操作規制機構５５および第２操作規制機構６０の他方が、解除部材４１と係合して解除部材４１の動作を規制し、主操作部材５０を用いた解除部材４１の操作が規制される。このようなベビーカー１０によれば、第１操作規制機構５５および第２操作規制機構６０によって、解除部材４１の動作と主操作部材５０の動作が、それぞれ別個に規制されることになる。したがって、主操作部材５０を用いた解除部材４１の操作をより確実に規制することができる。これにより、誤操作等によって意図せずベビーカー本体１１の折り畳み動作が始まってしまうことをより効果的に防止することができる。 Further, according to the present embodiment, one of the first operation restriction mechanism 55 and the second operation restriction mechanism 60 is engaged with the main operation member 50 to restrict the operation of the main operation member 50, and the main operation member 80. The operation of the release member 41 is restricted, and the other of the first operation restriction mechanism 55 and the second operation restriction mechanism 60 engages with the release member 41 to restrict the operation of the release member 41, and the main operation member 50 The operation of the release member 41 using is regulated. According to such a stroller 10, the operation of the release member 41 and the operation of the main operation member 50 are separately regulated by the first operation restriction mechanism 55 and the second operation restriction mechanism 60. Therefore, the operation of the release member 41 using the main operation member 50 can be more reliably regulated. Thereby, it can prevent more effectively that folding operation | movement of the baby stroller main body 11 starts unintentionally by misoperation etc.
　さらに、折り畳み操作機構４０、第１操作規制機構５５および第２操作規制機構６０のすべてがハンドル３６に設けられており、操作性に優れる。 Furthermore, all of the folding operation mechanism 40, the first operation restriction mechanism 55, and the second operation restriction mechanism 60 are provided on the handle 36, and the operability is excellent.
　なお、上述した実施の形態に対して様々な変更を加えることが可能である。以下、変形の一例について説明する。 Note that various modifications can be made to the above-described embodiment. Hereinafter, an example of modification will be described.
　例えば、上述した実施の形態において、第２操作規制機構６０が設けられている側の伝達手段４３、すなわち、左側の伝達手段４３（図５および図６における図面の右側の伝達手段）が、主操作部材５０に接続された第１接続部材４５と、解除部材４１に接続された第２接続部材４６と、第１接続部材４５および第２接続部材４６を連結する保持解除部材４４と、を有している例を示した。しかしながら、これに限られず、伝達手段４３が、単一の接続部材と、この接続部材上に保持された保持解除部材４４と、を有するようにしてもよい。より具体的には、伝達手段４３を、主操作部材５０と解除部材４１とに両端を接続された線状部材と、この線状部材上に取り付けられた保持解除部材４４と、から構成されるようにしてもよい。あるいは、このような接続部材が、さらに、線状部材が挿通する一以上の筒状部材を有するようにしてもよい。筒状部材は、保持解除部材４４と主操作部材５０との間並びに保持解除部材４４と解除部材４１との間のうちの一方または両方に配置され得る。 For example, in the above-described embodiment, the transmission means 43 on the side where the second operation restriction mechanism 60 is provided, that is, the transmission means 43 on the left side (the transmission means on the right side of the drawings in FIGS. 5 and 6) is the main. A first connection member 45 connected to the operation member 50; a second connection member 46 connected to the release member 41; and a holding release member 44 that connects the first connection member 45 and the second connection member 46. An example is shown. However, the present invention is not limited to this, and the transmission means 43 may include a single connecting member and a holding release member 44 held on the connecting member. More specifically, the transmission means 43 is composed of a linear member having both ends connected to the main operation member 50 and the release member 41, and a holding release member 44 attached on the linear member. You may do it. Alternatively, such a connecting member may further include one or more cylindrical members through which the linear members are inserted. The tubular member may be disposed between one or both of the holding release member 44 and the main operation member 50 and between the holding release member 44 and the release member 41.
　さらに、上述した実施の形態において説明したベビーカー１０のベビーカー本体１１の構成は、単なる例に過ぎない。例えば、特開２０１１－１４８４５４に開示されたベビーカーのように、前後方向に小型化するように折り畳んだ後にさらに折り畳んで幅方向にも小型化させ得るよう、ベビーカー１０のベビーカー本体１１が構成されていてもよい。具体的には、ベビーカー本体１１の幅方向に延びる部材、すなわち、ハンドル３６の中間部３８、フットレスト１７および後方連結材１９がヒンジ（屈曲点）を有し、これらの部材が、上述したように前後方向に小型化するように折り畳まれた後に、さらに、ヒンジを中心として屈曲し得るようにしてもよい。 Furthermore, the configuration of the stroller body 11 of the stroller 10 described in the above embodiment is merely an example. For example, the stroller body 11 of the stroller 10 is configured so that it can be further folded in the width direction after being folded so as to be reduced in size in the front-rear direction, as in the stroller disclosed in JP2011-148454A. May be. Specifically, members extending in the width direction of the stroller body 11, that is, the intermediate portion 38 of the handle 36, the footrest 17 and the rear connecting member 19 have hinges (bending points), and these members are as described above. After being folded so as to be reduced in size in the front-rear direction, it may be further bent around the hinge.
　さらに、上述した実施の形態において説明したベビーカー１０のベビーカー本体１１において、ハンドル１３が背面押し位置（後方位置）と対面押し位置（前方位置）との間を揺動可能に構成されている例を示した。すなわち、上述した実施の形態では、ハンドル３６が第１リンク材２６とは別途に設けられ、ハンドル３６がベビーカー本体１１のフレーム部２０に対して揺動可能に構成されている例を示した。しかしながら、例えば図１２に示すように、ハンドル３６が後方位置に固定され、背面押し位置から揺動不可能にベビーカー本体１１が構成されていてもよい。図１２に示す例においては、ハンドル３６の主部３７の下端部に相当する部分によって、一対の第１リンク材２６が構成されている。言い換えると、第１リンク材２６が、アームレスト２８との連結箇所を越えてさらに延び、ハンドル３６の一部分を構成するようになっている。このようなベビーカー本体１１においては、ハンドル３６の主部３７の下方部分に設けられた解除部材４１が、上述した実施の形態におけるロック部材３０としても機能し、第３リンク材３４と係合してベビーカー本体１１を展開した状態に維持するように構成され得る。このようなベビーカー１０においても、上述した実施の形態と同様の作用効果を得ることができる。 Further, in the stroller body 11 of the stroller 10 described in the above-described embodiment, an example in which the handle 13 is configured to be swingable between a back pushing position (rear position) and a facing pushing position (front position). Indicated. That is, in the above-described embodiment, an example in which the handle 36 is provided separately from the first link member 26 and the handle 36 is configured to be swingable with respect to the frame portion 20 of the stroller body 11 is shown. However, for example, as shown in FIG. 12, the stroller body 11 may be configured such that the handle 36 is fixed at the rear position and cannot be swung from the back pushing position. In the example shown in FIG. 12, a pair of first link members 26 is configured by a portion corresponding to the lower end portion of the main portion 37 of the handle 36. In other words, the first link member 26 further extends beyond the connecting portion with the armrest 28 and constitutes a part of the handle 36. In such a stroller body 11, the release member 41 provided in the lower portion of the main portion 37 of the handle 36 also functions as the lock member 30 in the above-described embodiment and engages with the third link member 34. The stroller body 11 can be configured to be maintained in an unfolded state. Even in such a stroller 10, it is possible to obtain the same operational effects as those of the above-described embodiment.
　なお、以上において上述した実施の形態に対するいくつかの変形例を説明してきたが、当然に、複数の変形例を適宜組み合わせて適用することも可能である。 In addition, although the some modification with respect to embodiment mentioned above was demonstrated above, naturally, it is also possible to apply combining several modifications suitably.
