Description

本発明は、折り畳み式のベビーカーに適用されるベビーカー用スタンド装置に関する。 The present invention relates to a stroller stand device applied to a folding stroller.

車体を使用状態と折り畳み状態との間で変形可能なベビーカーは周知である。このようなベビーカーを立ち姿勢に保持するために、車輪が取り付けられた脚部に対して回転可能に設けられたパイプ状の支持脚を所定位置でロックするスタンド装置が知られている（特許文献１）。 A baby stroller that can deform a vehicle body between a use state and a folded state is well known. In order to hold such a stroller in a standing position, there is known a stand device that locks a pipe-like support leg provided in a predetermined position so as to be rotatable with respect to a leg portion to which a wheel is attached (Patent Document). 1).

特開２００２−３３７６９５号公報JP 2002-337695 A

特許文献１のスタンド装置は、ベビーカーを立ち姿勢に保持する際には脚部に固定された断面Ｃ字状の樹脂製ホルダによって支持脚を両側から挟み込むことにより支持脚を斜め下向きにロックする。このロックの解放は樹脂製ホルダが弾性変形してその開口幅が支持脚よりも広がることによって達成される。このスタンド装置によってベビーカーが立ち姿勢に保持されている場合は支持脚が斜め下向きに繰り出されているため支持脚を上向きに回転させるモーメントが働く。 In the stand device of Patent Document 1, when the stroller is held in a standing position, the support leg is locked diagonally downward by sandwiching the support leg from both sides by a resin holder having a C-shaped cross section fixed to the leg portion. The release of the lock is achieved by the resin holder being elastically deformed and the opening width being wider than the support leg. When the stroller is held in a standing posture by the stand device, the supporting leg is extended obliquely downward, and therefore a moment for rotating the supporting leg upward works.

立ち姿勢の保持を安定させるには、樹脂製ホルダを変形し難くくして支持脚のロックを強くすることが望ましい。しかし、樹脂製ホルダが変形し難くなると樹脂製ホルダから支持脚が容易に外れ難くなるため、ロックの解放が困難になりスタンド装置の操作性が悪化する。従って、ロックを解放することを考慮した場合には支持脚のロックをあまり強くできないため、ベビーカーの立ち姿勢の保持性能を妥協せざるを得ない。なお、このスタンド装置は支持脚のロック及び解放のそれぞれで樹脂製ホルダの弾性変形が伴うとともに支持脚と樹脂製ホルダとが強く摩擦するため耐久性に不安がある。また、一般に弾性係数は温度依存性があるので、冬場の操作性が夏場に比べて悪化する等の季節によって操作性が変化する問題もある。 In order to stabilize the standing posture, it is desirable that the resin holder is not easily deformed and the support legs are strongly locked. However, if the resin holder is difficult to deform, the support legs are not easily detached from the resin holder, so that it is difficult to release the lock and the operability of the stand device is deteriorated. Therefore, in consideration of releasing the lock, the support leg cannot be locked so strongly, so that the holding performance of the stroller must be compromised. In addition, this stand device is uneasy about durability because the resin holder is elastically deformed in each of the locking and releasing of the support leg and the support leg and the resin holder are rubbed strongly. In addition, since the elastic modulus is generally temperature-dependent, there is a problem that the operability changes depending on the season, such as the operability in winter is worse than that in summer.

そこで、本発明は、操作性を損なうことなくベビーカーの立ち姿勢の保持性能を向上できるベビーカー用スタンド装置を提供することを目的とする。 Then, an object of this invention is to provide the stand apparatus for strollers which can improve the holding | maintenance performance of the standing posture of a stroller, without impairing operativity.

以下、本発明のベビーカー用スタンド装置について説明する。なお、本発明の理解を容易にするために添付図面の参照符号を括弧書きにて付記するが、それにより本発明が図示の形態に限定されるものではない。 Hereinafter, the stroller stand device of the present invention will be described. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

本発明の第１のベビーカー用スタンド装置は、車輪（９）が取り付けられた脚部（４）を含む車体（２）を使用状態と折り畳み状態との間で変形可能なベビーカー（１）に適用され、前記折り畳み状態の前記車体を前記車輪が接地した状態で前記脚部が上向きの立ち姿勢に保持できるベビーカー用スタンド装置（２０）において、前記車輪の近くに配置されて前記脚部に固定されたベース部（２１）と、前記車体の左右方向に延びる軸線（Ａｘ）の回りに回転可能な状態で前記ベース部に取り付けられ、前記ベース部に対する取り付け位置から一方向に延びる支持脚（２２）と、前記支持脚に設けられて前記車体が前記立ち姿勢に保持される際に接地する足部（２３）と、前記ベース部と前記支持脚との間に介在し、前記車体が前記立ち姿勢の場合に前記支持脚が斜め下向きとなる支持位置で前記支持脚の回転を阻止できるロック機構（２４）と、を備え、前記ロック機構は、前記支持脚の回転方向に関して前記支持脚に対する相対移動が阻止されかつ前記回転方向と異なる所定方向に関して前記支持脚に対する相対移動が許容された状態で前記支持脚に設けられることにより、前記所定方向に関して前記ベース部に対する相対移動が可能な状態とされるロック部材（３０）と、前記ベース部に設けられるとともに、前記車体が前記立ち姿勢の場合に前記支持脚が前記支持位置から上向きに回転することが阻止されるように前記支持位置で前記ロック部材と突き当たり、かつ前記ベース部に対して前記ロック部材が前記所定方向に相対移動した際に前記支持脚の回転が許容されるように前記ロック部材と離間するロック壁（３５）と、前記ロック部材と前記ロック壁とが突き当たった状態で前記支持脚に対して前記ロック部材が前記所定方向に相対移動することが制限されるように前記ロック部材を付勢する付勢手段（４６）と、前記ベース部及び前記支持脚のそれぞれに対して相対移動可能な解放操作部材と、前記解放操作部材に設けられ、前記ベース部及び前記支持脚のそれぞれに対して相対移動するように前記解放操作部材を操作した場合に前記付勢手段の付勢力に抗して前記ロック部材が前記所定方向に前記支持脚に対して相対移動するように前記ロック部材を案内する案内手段としての長孔（５６）と、を有し、前記支持脚と前記解放操作部材とが前記軸線の方向に延びる共通の支持軸を介して回転可能な状態で前記ベース部に取り付けられ、前記長孔が前記所定方向に対して傾くようにして前記解放操作部材に形成されているものである。
The first stroller stand device of the present invention is applied to a stroller (1) in which a vehicle body (2) including a leg (4) to which wheels (9) are attached can be deformed between a use state and a folded state. In the stroller stand device (20) in which the leg portion can be held in an upward standing posture with the wheel in contact with the vehicle body in the folded state, the stroller stand device (20) is disposed near the wheel and fixed to the leg portion. And a support leg (22) which is attached to the base portion in a state of being rotatable around an axis (Ax) extending in the left-right direction of the vehicle body and extends in one direction from an attachment position with respect to the base portion. And a foot (23) that is provided on the support leg and contacts the ground when the vehicle body is held in the standing posture, and is interposed between the base portion and the supporting leg, and the vehicle body is in the standing posture. The locking mechanism support leg can prevent rotation of the support legs in the supporting position that diagonally downward and (2 4) in the case, wherein the locking mechanism is moved relative to said supporting leg with respect to the rotational direction of the supporting leg wherein the Rukoto provided in the supporting leg in a state in which the relative movement is allowed with respect to the support legs, is relative movement between ready for said predetermined direction with respect to said base portion but respect the blocked and a different predetermined direction wherein the direction of rotation The locking member (3 0 ) and the base portion, and the support leg at the support position is prevented from rotating upward from the support position when the vehicle body is in the standing posture. The support leg is allowed to rotate when it comes into contact with the lock member and the lock member moves relative to the base portion in the predetermined direction. A locking wall (35) spaced apart and sea urchin said locking member is restricted from the locking member relative to the support leg in a state in which said locking member and the locking wall abuts are relatively moved in the predetermined direction A biasing means (46) for biasing the lock member, a release operation member movable relative to each of the base portion and the support leg, and the release operation member. When the release operation member is operated so as to move relative to each of the support legs, the lock member moves relative to the support legs in the predetermined direction against the urging force of the urging means. wherein a long hole (56) as guide means for guiding the locking member, have a so, the support legs and the release operation member and is Jo rotatable via a common support shaft extending in a direction of said axis The release operation member is attached to the base portion in such a manner that the elongated hole is inclined with respect to the predetermined direction .

このベビーカー用スタンド装置は、ロック機構が支持脚を支持位置でロックする際に支持脚に設けられたロック部材とベース部に設けられたロック壁とが突き当たるので斜め下向きの支持脚が上向きに回転することが阻止される。つまり、ロック部材がロック壁に突き当たることにより支持脚が機械的にロックされる。そして、ロック部材が所定方向に移動することによりロック部材がロック壁から離間するため支持脚のロックが解放される。従って、支持脚のロックの強さを十分に確保でき、しかも支持脚のロックの強さとロックを解放する操作性とが直接的に関連しない。そのため、操作性を損なうことなくベビーカーの立ち姿勢の保持性能を向上できる。また、支持脚のロックが簡単に解放されることがないので、支持位置における支持脚の地面に対する傾き角を自由に設定できる。これにより、支持脚を必要以上に長くしなくても地面に対する傾き角を小さくできるので車体を立ち姿勢に保持する際に車輪の接地位置から足部の接地位置までの距離を十分に確保できる。従って、支持脚を必要以上に長くすることなく車体を立ち姿勢に安定的に保持できる。更に、ロック機構が付勢手段を有しているのでロックを解放する際の操作力を付勢手段の設定を変えることにより調整可能である。また、解放操作部材の操作によりロック部材を移動させてロックの解放を容易に行うことができるため操作性が向上する。解放操作部材を回転可能に支持する支持軸が支持脚の支持軸と共通であるので部品点数を削減できるとともに、ロック機構の小型化に貢献できる。
In this stroller stand device, when the lock mechanism locks the support leg at the support position, the lock member provided on the support leg and the lock wall provided on the base portion abut against each other, so that the support leg inclined downward rotates upward. To be prevented. That is, the support leg is mechanically locked when the lock member hits the lock wall. When the lock member moves in a predetermined direction, the lock member is separated from the lock wall, so that the support leg is unlocked. Therefore, the locking strength of the support leg can be sufficiently secured, and the locking strength of the support leg and the operability for releasing the lock are not directly related. Therefore, it is possible to improve the performance of maintaining the stroller's standing posture without impairing operability. Further, since the lock of the support leg is not easily released, the inclination angle of the support leg with respect to the ground at the support position can be freely set. This makes it possible to reduce the angle of inclination with respect to the ground without making the support legs longer than necessary, so that a sufficient distance from the wheel contact position to the foot contact position can be secured when the vehicle body is held in a standing position. Therefore, the vehicle body can be stably held in a standing posture without making the support legs longer than necessary. Further, since the lock mechanism has the urging means, the operation force when releasing the lock can be adjusted by changing the setting of the urging means. Further, the operability is improved because the lock member can be easily released by moving the lock member by operating the release operation member. Since the support shaft that rotatably supports the release operation member is common to the support shaft of the support leg, the number of parts can be reduced and the locking mechanism can be reduced in size.

本発明の第２のベビーカー用スタンド装置は、車輪（９）が取り付けられた脚部（４）を含む車体（２）を使用状態と折り畳み状態との間で変形可能なベビーカー（１）に適用され、前記折り畳み状態の前記車体を前記車輪が接地した状態で前記脚部が上向きの立ち姿勢に保持できるベビーカー用スタンド装置（２０）において、前記車輪の近くに配置されて前記脚部に固定されたベース部（２１）と、前記車体の左右方向に延びる軸線（Ａｘ）の回りに回転可能な状態で前記ベース部に取り付けられ、前記ベース部に対する取り付け位置から一方向に延びる支持脚（２２）と、前記支持脚に設けられて前記車体が前記立ち姿勢に保持される際に接地する足部（２３）と、前記ベース部と前記支持脚との間に介在し、前記車体が前記立ち姿勢の場合に前記支持脚が斜め下向きとなる支持位置で前記支持脚の回転を阻止できるロック機構（２４）と、を備え、前記ロック機構は、前記支持脚の回転方向に関して前記支持脚に対する相対移動が阻止されかつ前記回転方向と異なる所定方向に関して前記支持脚に対する相対移動が許容された状態で前記支持脚に設けられることにより、前記所定方向に関して前記ベース部に対する相対移動が可能な状態とされるロック部材（３０）と、前記ベース部に設けられるとともに、前記車体が前記立ち姿勢の場合に前記支持脚が前記支持位置から上向きに回転することが阻止されるように前記支持位置で前記ロック部材と突き当たり、かつ前記ベース部に対して前記ロック部材が前記所定方向に相対移動した際に前記支持脚の回転が許容されるように前記ロック部材と離間するロック壁（３５）と、前記ロック部材と前記ロック壁とが突き当たった状態で前記支持脚に対して前記ロック部材が前記所定方向に相対移動することが制限されるように前記ロック部材を付勢する付勢手段（４６）と、を有し、前記ベース部は、前記脚部から離れる方向に互いに平行に延びていて、前記支持脚の端部を挟み込むようにして前記軸線の回りを回転可能に支持する一対の支持部材（２５）と、前記一対の支持部材の各基端間に位置し、前記支持脚の前記端部と対向する壁部（２７）と、を有し、前記支持脚の前記端部、前記一対の支持部材及び前記壁部にて規定される空間（Ｓ１）を埋めるスペーサ（２８）が前記支持脚に設けられているものである。The second stroller stand device of the present invention is applied to a stroller (1) that can deform a vehicle body (2) including a leg (4) to which a wheel (9) is attached between a use state and a folded state. In the stroller stand device (20) in which the leg portion can be held in an upward standing posture with the wheel in contact with the vehicle body in the folded state, the stroller stand device (20) is disposed near the wheel and fixed to the leg portion. And a support leg (22) which is attached to the base portion in a state of being rotatable around an axis (Ax) extending in the left-right direction of the vehicle body and extends in one direction from an attachment position with respect to the base portion. And a foot (23) that is provided on the support leg and contacts the ground when the vehicle body is held in the standing posture, and is interposed between the base portion and the supporting leg, and the vehicle body is in the standing posture. A lock mechanism (24) capable of preventing rotation of the support leg at a support position where the support leg is obliquely downward, and the lock mechanism is capable of relative movement with respect to the support leg with respect to the rotation direction of the support leg. A lock that is provided in the support leg in a state in which relative movement with respect to the support leg is allowed with respect to a predetermined direction that is blocked and different from the rotation direction, so that relative movement with respect to the base portion is possible with respect to the predetermined direction. A member (30) and the lock member at the support position so as to prevent the support leg from rotating upward from the support position when the vehicle body is in the standing posture. The support leg is allowed to rotate when it hits and the lock member moves relative to the base portion in the predetermined direction. The lock member (35) spaced apart from the lock member and the lock member and the lock wall are in contact with each other, and the lock member is restricted from moving relative to the support leg in the predetermined direction. Biasing means (46) for biasing the lock member, and the base portions extend in parallel to each other in a direction away from the leg portion, and sandwich the end portion of the support leg. A pair of support members (25) that rotatably support the periphery of the axis, and a wall portion (27) that is positioned between the base ends of the pair of support members and faces the end portions of the support legs; The support leg is provided with a spacer (28) that fills the space (S1) defined by the end of the support leg, the pair of support members, and the wall part.

このベビーカー用スタンド装置は、ロック機構が支持脚を支持位置でロックする際に支持脚に設けられたロック部材とベース部に設けられたロック壁とが突き当たるので斜め下向きの支持脚が上向きに回転することが阻止される。つまり、ロック部材がロック壁に突き当たることにより支持脚が機械的にロックされる。そして、ロック部材が所定方向に移動することによりロック部材がロック壁から離間するため支持脚のロックが解放される。従って、支持脚のロックの強さを十分に確保でき、しかも支持脚のロックの強さとロックを解放する操作性とが直接的に関連しない。そのため、操作性を損なうことなくベビーカーの立ち姿勢の保持性能を向上できる。また、支持脚のロックが簡単に解放されることがないので、支持位置における支持脚の地面に対する傾き角を自由に設定できる。これにより、支持脚を必要以上に長くしなくても地面に対する傾き角を小さくできるので車体を立ち姿勢に保持する際に車輪の接地位置から足部の接地位置までの距離を十分に確保できる。従って、支持脚を必要以上に長くすることなく車体を立ち姿勢に安定的に保持できる。更に、ロック機構が付勢手段を有しているのでロックを解放する際の操作力を付勢手段の設定を変えることにより調整可能である。また、スペーサによって支持脚の端部、一対の支持部材及び壁部にて規定される空間を埋めることができるので、その空間が外部に露出することを回避できる。これにより支持脚の回転時における安全性が向上する。In this stroller stand device, when the lock mechanism locks the support leg at the support position, the lock member provided on the support leg and the lock wall provided on the base portion abut against each other, so that the support leg inclined downward rotates upward. To be prevented. That is, the support leg is mechanically locked when the lock member hits the lock wall. When the lock member moves in a predetermined direction, the lock member is separated from the lock wall, so that the support leg is unlocked. Therefore, the locking strength of the support leg can be sufficiently secured, and the locking strength of the support leg and the operability for releasing the lock are not directly related. Therefore, it is possible to improve the performance of maintaining the stroller's standing posture without impairing operability. Further, since the lock of the support leg is not easily released, the inclination angle of the support leg with respect to the ground at the support position can be freely set. This makes it possible to reduce the angle of inclination with respect to the ground without making the support legs longer than necessary, so that a sufficient distance from the wheel contact position to the foot contact position can be secured when the vehicle body is held in a standing position. Therefore, the vehicle body can be stably held in a standing posture without making the support legs longer than necessary. Further, since the lock mechanism has the urging means, the operation force when releasing the lock can be adjusted by changing the setting of the urging means. Further, since the space defined by the end portion of the support leg, the pair of support members, and the wall portion can be filled with the spacer, it is possible to avoid exposing the space to the outside. Thereby, the safety | security at the time of rotation of a support leg improves.

本発明の第１又は第２のベビーカー用スタンド装置の一態様において、前記支持脚は内部空間（Ｓ２）を有した中空状に構成されており、前記ロック機構は、前記ロック部材を前記所定方向に移動可能な状態に支持し、かつ前記ロック部材を付勢できる状態で前記付勢手段が取り付けられた支持手段（３２）を更に有し、前記支持手段は、前記付勢手段とともに前記支持脚の前記内部空間に収められてもよい。この場合には、支持脚の内部空間に支持手段と付勢手段とが収められることにより支持手段及び付勢手段のそれぞれが外部に露出することを防止できる。これにより、操作を行う使用者が支持手段及び付勢手段に触れることを避けることができるので安全性が高まるとともに見栄えも向上する。
In one aspect of the first or second stroller stand device of the present invention, the support leg is formed in a hollow shape having an internal space (S2), and the lock mechanism moves the lock member in the predetermined direction. And further supporting means (32) to which the urging means is attached in a state in which the lock member can be urged, and the support means together with the urging means and the support leg. In the internal space. In this case, the support means and the urging means are accommodated in the internal space of the support leg, thereby preventing the support means and the urging means from being exposed to the outside. Thereby, since it can avoid that the user who performs operation touches a support means and a biasing means, safety | security increases and appearance also improves.

本発明の第１又は第２のベビーカー用スタンド装置の一態様において、前記ロック部材は、前記軸線の方向に前記支持脚から突出した状態で、かつ前記所定方向としての前記支持脚の長手方向に関して前記支持脚に対する相対移動が許容された状態で前記支持脚に設けられてもよい。この場合には、支持脚の幅方向にロック部材の可動スペースを確保する必要がないのでロック機構の小型化に貢献できる。
In one aspect of the first or second stroller stand device of the present invention, the lock member protrudes from the support leg in the direction of the axis and relates to the longitudinal direction of the support leg as the predetermined direction. The support leg may be provided in a state in which relative movement with respect to the support leg is allowed. In this case, it is not necessary to secure a movable space for the lock member in the width direction of the support leg, which can contribute to downsizing of the lock mechanism.

本発明の第１又は第２のベビーカー用スタンド装置の一態様において、前記ロック機構は、前記使用状態で前記足部が接地しない姿勢に前記支持脚が保持されるように前記ロック部材に噛み合う第１保持部（３６）と、前記折り畳み状態で前記足部が前記脚部に接近する姿勢に前記支持脚が保持されるように前記ロック部材に噛み合う第２保持部（３７）と、を更に有してもよい。この態様によれば、車体が使用状態の際に支持脚が第１保持部にて保持されることにより足部が接地することを回避できるので、ベビーカーの使用時に支持脚が邪魔になることがない。また、第２保持部にて支持脚が保持されることにより折り畳み状態で支持脚が脚部に接近するため、折り畳まれたベビーカーを寝かせた姿勢にしたときに支持脚が邪魔になり難い。従って、自動車のトランク等の収納スペースへのベビーカーの収納が容易になる。
In one aspect of the first or second stroller stand device of the present invention, the lock mechanism is configured to engage with the lock member so that the support leg is held in a posture in which the foot portion does not come in contact with the use state. 1 holding part (36), and a second holding part (37) meshing with the lock member so that the support leg is held in a posture in which the foot part approaches the leg part in the folded state. May be. According to this aspect, when the vehicle body is in use, the support legs can be prevented from being grounded by being held by the first holding part, so that the support legs can become an obstacle when the stroller is used. Absent. In addition, since the support legs are held by the second holding section and the support legs approach the leg sections in the folded state, the support legs are unlikely to get in the way when the folded stroller is placed in a lying position. Accordingly, the stroller can be easily stored in a storage space such as the trunk of the automobile.

この態様においては、前記ベース部は前記軸線を中心とした円弧部（３１）を有し、前記円弧部の外周には、前記ロック壁、前記第１保持部及び前記第２保持部がそれぞれ設けられてもよい。この場合は、ロック壁、第１保持部及び第２保持部が円弧部に集約されているためロック機構の小型化に貢献できる。 In this aspect, the base portion has an arc portion (31) centered on the axis, and the lock wall, the first holding portion, and the second holding portion are provided on the outer periphery of the arc portion, respectively. May be. In this case, since the lock wall, the first holding portion, and the second holding portion are concentrated in the arc portion, it is possible to contribute to downsizing of the lock mechanism.

本発明の第１又は第２のベビーカー用スタンド装置の一態様において、前記足部は、前記軸線の方向と同方向に延びていて前記支持脚の長さよりも長くてもよい。この態様によれば、支持脚の長さよりも長い足部が軸線の方向と同方向に延びているので、立ち姿勢に保持された車体の左右方向の安定性が向上する。この態様においては、前記支持脚と前記足部とは、一本の棒状部材がＬ字型に曲げられることにより構成されていてもよい。この場合は一本の棒状部材で支持脚及び足部が構成されるので、これらを別部品で構成する場合に比べて部品点数を削減できる。 In one aspect of the first or second stroller stand device of the present invention, the foot portion may extend in the same direction as the axis and be longer than the length of the support leg. According to this aspect, since the foot portion longer than the length of the support leg extends in the same direction as the axial direction, the stability in the left-right direction of the vehicle body held in the standing posture is improved. In this aspect, the support leg and the foot may be configured by bending a single bar-shaped member into an L shape. In this case, since the support leg and the foot are configured by a single bar-shaped member, the number of components can be reduced as compared with the case where these are configured by separate components.

以上説明したように、本発明のベビーカー用スタンド装置によれば、ロック部材がロック壁に突き当たることにより支持脚が機械的にロックされ、ロック部材が所定方向に移動することによりロック部材がロック壁から離間するため支持脚のロックが解放されるので、操作性を損なうことなくベビーカーの立ち姿勢の保持性能を向上できる。また、支持脚を必要以上に長くしなくても地面に対する傾き角を小さくできるので立ち姿勢に保持する際に車輪の接地位置から足部の接地位置までの距離を十分に確保できる。このため、立ち姿勢に保持する際の安定性を高めることができる。 As described above, according to the stroller stand device of the present invention, the support leg is mechanically locked when the lock member hits the lock wall, and the lock member moves in a predetermined direction so that the lock member is locked. Since the support legs are unlocked because they are separated from each other, it is possible to improve the holding performance of the baby stroller without impairing operability. In addition, since the inclination angle with respect to the ground can be reduced without making the support legs longer than necessary, a sufficient distance from the wheel contact position to the foot contact position can be ensured when maintaining the standing posture. For this reason, the stability at the time of hold | maintaining to a standing posture can be improved.

Is possible. The left and right front legs 3 are connected by a connecting member 7. The left and right rear legs 4 are also connected by a connecting member (not shown). A front wheel 8 is attached to the lower end of the front leg 3, and a rear wheel 9 is attached to the lower end of the rear leg 4.

前脚部３はその上端において手押しフレーム６と支持ピン１０を介して回転可能に連結されている。後脚部４も同様にその上端において手押しフレーム６と支持ピン１１を介して回転可能に連結されている。クロスフレーム５は中央部で互いに交差するように回転可能に連結された一対の連結部材１２を有している。一対の連結部材１２のそれぞれの両端部は、対角線上に位置する前脚部３及び後脚部４に回転可能に連結されている。手押しフレーム６は、車体２の左右に配置される一対のバックフレーム１３と、各バックフレーム１３の上端部にはハンドル部１４が取り付けられている。ベビーカー１のシート部１５はバックフレーム１３等に支持されている。また、ベビーカー１にはシート部１５の上方を覆うことができる折り畳み自在のサンシェード１６が設けられている。各前輪８は共通の軸線の回りに回転可能な一対のタイヤ１８を含んでいる。各後輪９も同様に共通の軸線の回りに回転可能なタイヤ１９を含んでいる。 The front leg 3 is rotatably connected to the upper end of the front leg 3 via a hand push frame 6 and a support pin 10. Similarly, the rear leg portion 4 is rotatably connected to the upper end of the rear leg portion 4 via a hand push frame 6 and a support pin 11. The cross frame 5 has a pair of connecting members 12 that are rotatably connected so as to cross each other at the center. Both end portions of the pair of connecting members 12 are rotatably connected to the front leg portion 3 and the rear leg portion 4 that are positioned on a diagonal line. The hand push frame 6 has a pair of back frames 13 disposed on the left and right sides of the vehicle body 2, and a handle portion 14 is attached to the upper end of each back frame 13. The seat portion 15 of the stroller 1 is supported by the back frame 13 or the like. Further, the stroller 1 is provided with a foldable sunshade 16 that can cover the upper portion of the seat portion 15. Each front wheel 8 includes a pair of tires 18 that can rotate about a common axis. Each rear wheel 9 also includes a tire 19 that can rotate about a common axis.

ベビーカー１には、折り畳み状態の車体２を後輪９が接地した状態で後脚部４が上向きの立ち姿勢に保持するためのスタンド装置２０が設けられている。図２は折り畳み状態の車体２がスタンド装置２０にて立ち姿勢に保持された状態を示した斜視図である。図３は折り畳み状態の車体２が寝かされた姿勢で置かれた状態を示した斜視図である。図４は図２の部分拡大図であり、図５は図４の矢印Vの方向から見た状態を示した図である。 The stroller 1 is provided with a stand device 20 for holding the rear leg portion 4 in an upward standing posture with the rear wheel 9 in contact with the folded vehicle body 2. FIG. 2 is a perspective view showing a state in which the folded vehicle body 2 is held in a standing posture by the stand device 20. FIG. 3 is a perspective view showing a state in which the vehicle body 2 in a folded state is placed in a lying position. 4 is a partially enlarged view of FIG. 2, and FIG. 5 is a view showing a state viewed from the direction of arrow V in FIG.

スタンド装置２０は、後輪９の近くに配置されて後脚部４に固定されたベース部２１と、車体２の左右方向に延びる軸線Ａｘの回りに回転可能な状態でベース部２１に取り付けられた支持脚２２と、支持脚２２の先端部に設けられた足部２３と、ベース部２１と支持脚２２との間に介在するロック機構２４とを備えている。ベース部２１はねじ止めされて後脚部４に固定されている。支持脚２２はベース部２１に対する取り付け位置から一方向に延びている。足部２３は軸線Ａｘの方向と同方向に延びていて支持脚２２よりも長い。これにより、スタンド装置２０が車体２を立ち姿勢に保持した際に車体２の左右方向の安定性が向上する。支持脚２２及び足部２３は中空の棒状部材である一本のパイプ材がＬ字型に曲げられることにより構成されている。そのため、支持脚２２及び足部２３を別部品で構成する場合に比べて部品点数を削減できる。 The stand device 20 is attached to the base portion 21 so as to be rotatable about an axis Ax extending in the left-right direction of the vehicle body 2 and a base portion 21 disposed near the rear wheel 9 and fixed to the rear leg portion 4. A support leg 22, a foot 23 provided at the tip of the support leg 22, and a lock mechanism 24 interposed between the base 21 and the support leg 22. The base portion 21 is fixed to the rear leg portion 4 with screws. The support leg 22 extends in one direction from the attachment position with respect to the base portion 21. The foot 23 extends in the same direction as the direction of the axis Ax and is longer than the support leg 22. Thereby, when the stand device 20 holds the vehicle body 2 in the standing posture, the stability of the vehicle body 2 in the left-right direction is improved. The support leg 22 and the foot portion 23 are configured by bending a single pipe member, which is a hollow rod-shaped member, into an L shape. Therefore, the number of parts can be reduced as compared with the case where the support leg 22 and the foot part 23 are constituted by different parts.

ベース部２１は後脚部４から離れる方向に互いに平行に延び、かつ支持脚２２の端部２２ａを挟み込む一対の支持部材２５を備えている。一対の支持部材２５と支持脚２２の端部２２ａとは軸線Ａｘの方向に延びる支持軸２６にて貫かれた状態で互いに連結されている。これにより、支持脚２２は一対の支持部材２５によって軸線Ａｘの回りを回転可能な状態で支持される。ベース部２１には一対の支持部材２５の各基端間に位置して支持脚２２の端部２２ａと対向する壁部２７が設けられている。支持脚２２には、端部２２ａ、一対の支持部材２５及び壁部２７にて規定される空間Ｓ１を埋めるスペーサ２８が設けられている。このスペーサ２８により空間Ｓ１が埋められることで、空間Ｓ１が外部に露出することを回避できるので、支持脚２２の回転時における安全性が向上する。 The base portion 21 includes a pair of support members 25 that extend in parallel to each other in a direction away from the rear leg portion 4 and sandwich an end portion 22 a of the support leg 22. The pair of support members 25 and the end portions 22a of the support legs 22 are connected to each other while being penetrated by a support shaft 26 extending in the direction of the axis Ax. Thereby, the support leg 22 is supported by the pair of support members 25 in a state of being rotatable around the axis Ax. The base portion 21 is provided with a wall portion 27 that is located between the base ends of the pair of support members 25 and faces the end portions 22 a of the support legs 22. The support leg 22 is provided with a spacer 28 that fills the space S <b> 1 defined by the end 22 a, the pair of support members 25, and the wall 27. Since the space S1 is filled with the spacer 28, the space S1 can be prevented from being exposed to the outside, and thus the safety during the rotation of the support leg 22 is improved.

ロック機構２４は、支持脚２２を図２及び図４に示したように車体２が立ち姿勢の場合に斜め下向きとなる支持位置でロックできるとともに、車体２の状態に合わせて支持位置とは異なる複数の位置に支持脚２２を保持することができる。即ち、ロック機構２４は、支持位置に加えて、車体２が使用状態の場合に適した第１保持位置（図１参照）及び車体２が折り畳み状態で自動車のトランク等の収納スペースに収納される場合に適した第２保持位置（図３参照）に支持脚２２を保持できる。図１から明らかなように、車体が使用状態の際に支持脚２２が第１保持位置に保持されて足部２３が接地することが回避できるので、ベビーカー１の使用時に支持脚２２が邪魔になることがない。また、図３から明らかなように、第２保持位置に保持されることにより折り畳み状態で支持脚２２が後脚部４に接近するので、折り畳まれた車体２を寝かせた姿勢にしたときに支持脚２２が邪魔になり難い。従って自動車のトランク等の収納スペースへのベビーカー１の収納が容易になる。 The lock mechanism 24 can lock the support leg 22 at a support position that is obliquely downward when the vehicle body 2 is in a standing posture as shown in FIGS. 2 and 4, and is different from the support position according to the state of the vehicle body 2. The support legs 22 can be held at a plurality of positions. That is, in addition to the support position, the lock mechanism 24 is housed in a first holding position (see FIG. 1) that is suitable when the vehicle body 2 is in use and in a storage space such as a trunk of an automobile when the vehicle body 2 is folded. The support leg 22 can be held at the second holding position (see FIG. 3) suitable for the case. As can be seen from FIG. 1, it is possible to avoid the foot 23 from being grounded while the support leg 22 is held at the first holding position when the vehicle body is in use, so that the support leg 22 is obstructive when the stroller 1 is used. Never become. Further, as is apparent from FIG. 3, the support leg 22 approaches the rear leg portion 4 in the folded state by being held at the second holding position, so that it is supported when the folded vehicle body 2 is placed in a lying position. Leg 22 is unlikely to get in the way. Therefore, it becomes easy to store the stroller 1 in a storage space such as a trunk of an automobile.

図６はロック機構２４の構造を説明する説明図である。図４〜図６に示すように、ロック機構２４は、ロック部材としてのロックピン３０と、ロックピン３０を上述した支持位置、第１保持位置及び第２保持位置のそれぞれの位置で拘束するための円弧部３１とを備えている。ロックピン３０は支持脚２２を貫くように延びている。ロックピン３０は支持脚２２の回転方向に関する相対移動が阻止されかつその回転方向とは異なる支持脚２２の長手方向に相対移動が許容された状態で支持脚２２に設けられている。ロックピン３０は円弧部３１に近づく方向に付勢された状態で支持されており、その支持は支持脚２２の内部空間に収められた支持手段としての支持ユニット３２にて行われる。支持ユニット３２の詳細は後述する。 FIG. 6 is an explanatory view for explaining the structure of the lock mechanism 24. As shown in FIGS. 4 to 6, the lock mechanism 24 restrains the lock pin 30 as a lock member and the lock pin 30 at each of the support position, the first holding position, and the second holding position described above. The arc part 31 is provided. The lock pin 30 extends through the support leg 22. The lock pin 30 is provided on the support leg 22 in a state in which relative movement in the rotation direction of the support leg 22 is prevented and relative movement is allowed in the longitudinal direction of the support leg 22 different from the rotation direction. The lock pin 30 is supported in a state of being urged in a direction approaching the arc portion 31, and the support is performed by a support unit 32 as a support means housed in the internal space of the support leg 22. Details of the support unit 32 will be described later.

円弧部３１は一対の支持部材２５の各先端部に設けられており、その外周が軸線Ａｘを中心とした円弧状に形成されている。円弧部３１の外周には、支持位置に対応するように形成されたロック壁３５と、第１保持位置に対応するように形成された第１保持部としての第１保持溝３６と、第２保持位置に対応するように形成された第２保持部としての第２保持溝３７とがそれぞれ設けられている。そのため、ロック壁３５、第１保持溝３６及び第２保持溝３７が円弧部３１に集約されるのでロック機構２４の小型化に貢献できる。 The arc portion 31 is provided at each tip portion of the pair of support members 25, and the outer periphery thereof is formed in an arc shape centering on the axis Ax. On the outer periphery of the arc portion 31, a lock wall 35 formed so as to correspond to the support position, a first holding groove 36 serving as a first holding portion formed so as to correspond to the first holding position, and a second A second holding groove 37 as a second holding portion formed so as to correspond to the holding position is provided. Therefore, the lock wall 35, the first holding groove 36, and the second holding groove 37 are concentrated in the arc portion 31, which can contribute to the downsizing of the lock mechanism 24.

図５に示したように、ロック壁３５は円弧部３１の半径方向に延びている。このため、支持位置においてロック壁３５がロックピン３０と突き当たることにより、支持脚２２は支持位置から上向きに（図５の上向き）に回転することが阻止される。ロックピン３０がロック壁３５に突き当たっている限り支持脚２２にモーメントを与えてもロックピン３０がロック壁３５から外れない。つまりロック機構２４はセルフロック状態に維持される。ロックピン３１が図５の位置から支持脚２２の長手方向に沿って円弧部３１から離れる向きに移動してロック壁３５から離間すると、支持脚２２のロックが解放されて支持脚２２の回転が許容される。 As shown in FIG. 5, the lock wall 35 extends in the radial direction of the arc portion 31. Therefore, when the lock wall 35 abuts against the lock pin 30 at the support position, the support leg 22 is prevented from rotating upward (upward in FIG. 5) from the support position. As long as the lock pin 30 abuts against the lock wall 35, the lock pin 30 does not come off the lock wall 35 even if a moment is applied to the support leg 22. That is, the lock mechanism 24 is maintained in a self-locking state. When the lock pin 31 moves away from the arc portion 31 along the longitudinal direction of the support leg 22 from the position of FIG. 5 and moves away from the lock wall 35, the lock of the support leg 22 is released and the support leg 22 rotates. Permissible.

各保持溝３６、３７は円弧部３１の中心側に後退した形状に形成されている。そのため、支持脚２２が第１保持位置に移動した場合にはロックピン３０が第１保持溝３６に嵌り込むため支持脚２２が第１保持位置に保持される。また、支持脚２２が第２保持位置に移動した場合にはロックピン３０が第２保持溝３７に嵌り込むため支持脚２２が第２保持位置に保持される。各保持溝３６、３７の両壁面はセルフロック状態とならない程度に傾斜している。そのため、各保持溝３６、３７にロックピン３０が嵌り込んだ状態からある程度の力で支持脚２２を回転させることにより各保持溝３６、３７からロックピン３０を外してロックを解放することが可能である。 Each holding groove 36, 37 is formed in a shape retreated to the center side of the arc portion 31. Therefore, when the support leg 22 is moved to the first holding position, the lock pin 30 is fitted into the first holding groove 36, so that the support leg 22 is held at the first holding position. When the support leg 22 is moved to the second holding position, the lock pin 30 is fitted into the second holding groove 37, so that the support leg 22 is held at the second holding position. Both wall surfaces of the holding grooves 36 and 37 are inclined so as not to be in a self-locking state. Therefore, it is possible to release the lock by releasing the lock pin 30 from each holding groove 36, 37 by rotating the support leg 22 with a certain force from the state in which the lock pin 30 is fitted in each holding groove 36, 37. It is.

図７はロックピン３０の支持等を行う支持ユニット３２の構造を示している。支持ユニット３２は図７の矢印で示すように支持脚２２の内部空間Ｓ２に挿入される。支持脚２２に挿入された支持ユニット３２は後端部に形成された取り付け孔４０と支持脚２２の側面に形成された取り付け孔４１とが一致した状態でこれらの取り付け孔４０、４１に不図示のリベットが挿入されることによって支持脚２２に固定される。 FIG. 7 shows the structure of a support unit 32 that supports the lock pin 30 and the like. The support unit 32 is inserted into the internal space S2 of the support leg 22 as shown by the arrow in FIG. The support unit 32 inserted into the support leg 22 is not shown in the attachment holes 40, 41 in a state where the attachment holes 40 formed in the rear end portion and the attachment holes 41 formed in the side surfaces of the support legs 22 coincide. This is fixed to the support leg 22 by inserting the rivet.

支持ユニット３２は、支持脚２２の内径に適合する形状を持つ本体部４３と、ロックピン３０を保持しつつ本体部４３に形成されたガイド４４に沿ってスライド可能なスライダ４５とを備えている。本体部４３とスライダ４５との間にはスライダ４５を付勢する付勢手段としてのコイルスプリング４６が圧縮状態で装着されている。 The support unit 32 includes a main body 43 having a shape that matches the inner diameter of the support leg 22, and a slider 45 that is slidable along a guide 44 formed on the main body 43 while holding the lock pin 30. . A coil spring 46 as a biasing means for biasing the slider 45 is mounted between the main body 43 and the slider 45 in a compressed state.

本体部４３の先端には上述したスペーサ２８が一体に形成されている。本体部４３には、支持ユニット３２が支持脚２２に挿入された場合に支持脚２２の端面が突き当たることにより支持ユニット３２を所定位置に位置決めする位置決め部４７が設けられている。支持脚２２の端面が位置決め部４７に突き当たった際には本体部４３に形成された軸支持孔４９と支持脚２２に形成された軸支持孔５０とが一致するように位置決め部４７が形成されている。支持脚２２がベース部２１に取り付けられる際には各軸支持孔４９、５０に支持軸２６が挿入される。 The spacer 28 described above is integrally formed at the tip of the main body 43. The main body 43 is provided with a positioning portion 47 for positioning the support unit 32 at a predetermined position when the end surface of the support leg 22 abuts when the support unit 32 is inserted into the support leg 22. When the end surface of the support leg 22 abuts against the positioning portion 47, the positioning portion 47 is formed so that the shaft support hole 49 formed in the main body portion 43 and the shaft support hole 50 formed in the support leg 22 coincide. ing. When the support leg 22 is attached to the base portion 21, the support shaft 26 is inserted into the shaft support holes 49 and 50.

スライダ４５は実線の位置から想像線の位置までの範囲内でスライド可能であり、その中央部にはロックピン３０が挿入されるロックピン保持孔５１が形成されている。ロックピン保持孔５１は支持脚２２に形成された長孔５２と重なるようになっている。ロックピン保持孔５１に挿入されたロックピン３０は、支持ユニット３２が支持脚２２に装着された際に長孔５２からその一部が軸線Ａｘの方向に突出した状態となる（図６参照）。長孔５２は支持脚２２の長手方向に延びていてロックピン３０の外径と略同一の幅を持っている。従って、スライダ４５に保持されたロックピン３０は支持脚２２の長手方向に関して支持脚２２に対する相対移動が許容されるとともに、支持脚２２の回転方向（幅方向）に関して支持脚２２に対する相対移動が阻止される。 The slider 45 is slidable within a range from the position of the solid line to the position of the imaginary line, and a lock pin holding hole 51 into which the lock pin 30 is inserted is formed at the center. The lock pin holding hole 51 overlaps with a long hole 52 formed in the support leg 22. The lock pin 30 inserted into the lock pin holding hole 51 is in a state where a part of the lock pin 30 protrudes in the direction of the axis Ax when the support unit 32 is attached to the support leg 22 (see FIG. 6). . The long hole 52 extends in the longitudinal direction of the support leg 22 and has substantially the same width as the outer diameter of the lock pin 30. Accordingly, the lock pin 30 held by the slider 45 is allowed to move relative to the support leg 22 with respect to the longitudinal direction of the support leg 22 and prevents relative movement with respect to the support leg 22 with respect to the rotation direction (width direction) of the support leg 22. Is done.

このように、ロックピン３０を支持する支持ユニット３２はコイルスプリング４６とともに支持脚２２の内部空間Ｓ２に収められているため、これらが外部に露出することを防止できる。これにより、使用者が支持ユニット３２やコイルスプリング４６に触れることを避けることができるので安全性が高まるとともに見栄えも向上する。また、ロックピン３０は軸線Ａｘの方向に支持脚２２から突出した状態でかつ支持脚２２の長手方向に関して支持脚２２に対する相対移動が許容された状態で支持脚２２に設けられている。このため、支持脚２２の幅方向にロックピン３０の可動スペースを確保する必要がないのでロック機構２４の小型化に貢献できる。 Thus, since the support unit 32 that supports the lock pin 30 is housed in the internal space S2 of the support leg 22 together with the coil spring 46, it can be prevented that they are exposed to the outside. Thereby, since it can avoid that a user touches the support unit 32 and the coil spring 46, safety | security increases and appearance also improves. The lock pin 30 is provided on the support leg 22 in a state of protruding from the support leg 22 in the direction of the axis Ax and in a state in which relative movement with respect to the support leg 22 is allowed in the longitudinal direction of the support leg 22. For this reason, since it is not necessary to ensure the movable space of the lock pin 30 in the width direction of the support leg 22, it is possible to contribute to the downsizing of the lock mechanism 24.

図４〜図６に示すように、ロック機構２４には支持位置における支持脚２２のロックを解放する操作を行うための解放操作部材５５が設けられている。解放操作部材５５は支持軸２６を介して回転可能な状態で円弧部３１を覆うようにしてベース部２１に取り付けられている。従って、支持軸２６が支持脚２２及び解放操作部材５５にて共用されるため、部品点数を削減できるとともにロック機構２４の小型化に貢献できる。 As shown in FIGS. 4 to 6, the lock mechanism 24 is provided with a release operation member 55 for performing an operation of releasing the lock of the support leg 22 at the support position. The release operation member 55 is attached to the base portion 21 so as to cover the arc portion 31 while being rotatable via the support shaft 26. Therefore, since the support shaft 26 is shared by the support leg 22 and the release operation member 55, the number of parts can be reduced and the locking mechanism 24 can be reduced in size.

解放操作部材５５にはロックピン３０を案内する案内手段としての長孔５６が形成されている。この長孔５６は図６に示すように支持脚２２に形成された長孔５２に対して斜め下向きに傾いている。従って、解放操作部材５５を図６の矢印で示した上向きに回転させると、ロックピン３０は長孔５６に沿って案内されながらコイルスプリング４６の弾性力に抗してベース部２１から離れる方向に移動する。これにより、ロックピン３０がロック壁３５から離間してロックが解放される。 The release operation member 55 is formed with a long hole 56 as a guide means for guiding the lock pin 30. As shown in FIG. 6, the long hole 56 is inclined obliquely downward with respect to the long hole 52 formed in the support leg 22. Accordingly, when the release operation member 55 is rotated upward as indicated by the arrow in FIG. 6, the lock pin 30 is guided along the elongated hole 56 in a direction away from the base portion 21 against the elastic force of the coil spring 46. Moving. Thereby, the lock pin 30 is separated from the lock wall 35 and the lock is released.

図５に示すように、解放操作部材５５には軸線Ａｘからオフセットされた位置に操作部５８が設けられている。操作部５８は車体２が折り畳み状態から使用状態へ変化する際にクロスフレーム５の端部が突き当たった状態で解放操作部材５５が上向きに回転するようにクロスフレーム５の端部に隣接している（図１も参照）。従って、折り畳み状態の車体２がスタンド装置２０にて立ち姿勢に保持されている状態から車体２を使用状態へ変化させると、クロスフレーム５の動きに連動して解放操作部材５５が上向きに回転してロックが解放される。図示を省略したが、解放操作部材５５にはロックが解放されるまで回転した場合に支持脚２２の側部に突き当たる当接部が設けられている。解放操作部材５５はロックが解放されてから更に上向きに回転するとその当接部によって支持脚２２を上向きに回転させることができる。そのため、ロック機構２４は、車体２が折り畳み状態から使用状態へ変化する過程で、ロックが解放した後に支持脚２２が更に回転して第１保持溝３６にロックピン３０を嵌り込ませて支持脚２２を第１保持位置に保持させることができる。これにより、車体２を折り畳み状態から使用状態へ変化させる際に、解放操作部材５５を手動で操作することなく自動的に支持脚２２を支持位置から第１保持位置へ変更することが可能である。 As shown in FIG. 5, the release operation member 55 is provided with an operation portion 58 at a position offset from the axis Ax. The operation portion 58 is adjacent to the end portion of the cross frame 5 so that the release operation member 55 rotates upward with the end portion of the cross frame 5 abutting when the vehicle body 2 changes from the folded state to the use state. (See also FIG. 1). Therefore, when the vehicle body 2 in the folded state is changed from the state in which the vehicle body 2 is held in the standing position to the use state, the release operation member 55 rotates upward in conjunction with the movement of the cross frame 5. The lock is released. Although not shown, the release operation member 55 is provided with an abutting portion that abuts against the side portion of the support leg 22 when rotated until the lock is released. When the release operation member 55 is further rotated upward after the lock is released, the support leg 22 can be rotated upward by the contact portion. Therefore, the lock mechanism 24 is a process in which the support leg 22 further rotates after the lock is released and the lock pin 30 is fitted into the first holding groove 36 in the process in which the vehicle body 2 changes from the folded state to the use state. 22 can be held at the first holding position. Accordingly, when the vehicle body 2 is changed from the folded state to the used state, the support leg 22 can be automatically changed from the support position to the first holding position without manually operating the release operation member 55. .

以上説明したように、スタンド装置２０によれば、ロック機構２４のロックピン３０がロック壁３５に突き当たることにより支持脚２２が機械的にロックされる。そして、ロックピン３０がコイルスプリング４６に逆らって支持脚２２の長手方向に移動することによりロックピン３０がロック壁３５から離間するため支持脚２２のロックが解放される。従って、支持脚２２のロックの強さを十分に確保でき、しかも支持脚２２のロックの強さとロックを解放する操作性とが直接的に関連しないため、操作性を損なうことなくベビーカー１の立ち姿勢の保持性能を向上できる。 As described above, according to the stand device 20, the support leg 22 is mechanically locked when the lock pin 30 of the lock mechanism 24 abuts against the lock wall 35. When the lock pin 30 moves in the longitudinal direction of the support leg 22 against the coil spring 46, the lock pin 30 is separated from the lock wall 35, so that the support leg 22 is unlocked. Accordingly, the locking strength of the support leg 22 can be sufficiently secured, and the locking strength of the support leg 22 and the operability for releasing the lock are not directly related to each other, so that the stroller 1 can stand up without impairing the operability. The posture holding performance can be improved.

また、スタンド装置２０は支持脚２２のロックが簡単に解放されることがないので、図８に示すように、支持位置における支持脚２２の地面Ｇに対する傾き角αを自由に設定できる。これにより、支持脚２２を必要以上に長くしなくても地面Ｇに対する傾き角αを小さくできるので車体２を立ち姿勢に保持する際に後輪９の接地位置Ｘａから足部２３の接地位置Ｘｂまでの距離Ｄを十分に確保できる。従って、支持脚２２を必要以上に長くすることなく車体２を立ち姿勢に安定的に保持できる。 Further, since the stand device 20 is not easily released from the lock of the support leg 22, as shown in FIG. 8, the inclination angle α of the support leg 22 with respect to the ground G at the support position can be freely set. As a result, the inclination angle α with respect to the ground G can be reduced without making the support legs 22 longer than necessary, so that when the vehicle body 2 is held in a standing position, the grounding position Xb of the foot 23 is changed from the grounding position Xa of the rear wheel 9. A sufficient distance D can be secured. Therefore, the vehicle body 2 can be stably held in a standing posture without making the support legs 22 longer than necessary.

以上の形態においては、後輪９が本発明に係る車輪に、後脚部４が本発明に係る脚部にそれぞれ相当する。但し、本発明は以上の形態に限定されず種々の形態にて実施できる。本発明に係るスタンド装置を適用できるベビーカーは、折り畳み状態の車体を立ち姿勢にした場合に前輪又は後輪のいずれか一方が接地するものであればよく、必ずしも後輪が接地するものでなくてもよい。 In the above embodiment, the rear wheel 9 corresponds to the wheel according to the present invention, and the rear leg portion 4 corresponds to the leg portion according to the present invention. However, the present invention is not limited to the above form and can be implemented in various forms. The stroller to which the stand device according to the present invention can be applied may be any one in which either the front wheel or the rear wheel is grounded when the folded body is in a standing posture, and the rear wheel is not necessarily grounded.

ロック機構は上記形態のものに限定されない。ロック機構に設けられた解放操作部材としては、例えば図９又は図１０に示した形態で実施することもできる。図９は解放操作部材の他の形態を示した斜視図である。図９の形態は支持脚２２に設けられたロックピン３０の両端部に解放操作部材６０が取り付けられたものである。解放操作部材６０はロックピン３０と一体であるため、解放操作部材６０を図９の矢印で示した支持脚２２の長手方向に操作することによってロックピン３０が長手方向に移動するためロックを解除することができる。図９の解放操作部材６０はロックピン３０と一体に形成することも可能であり、ロック機構の小型化に貢献できる。 The lock mechanism is not limited to the one described above. The release operation member provided in the lock mechanism can be implemented, for example, in the form shown in FIG. 9 or FIG. FIG. 9 is a perspective view showing another form of the release operation member. In the embodiment of FIG. 9, release operation members 60 are attached to both ends of the lock pin 30 provided on the support leg 22. Since the release operation member 60 is integrated with the lock pin 30, the lock pin 30 moves in the longitudinal direction by operating the release operation member 60 in the longitudinal direction of the support leg 22 indicated by the arrow in FIG. can do. The release operation member 60 of FIG. 9 can be formed integrally with the lock pin 30 and can contribute to the downsizing of the lock mechanism.

図１０は図９の形態とは異なる解放操作部材の他の形態を示した斜視図である。図１０の形態は、支持脚２２の中心線ＣＬの回りを回転可能な状態で支持脚２２の外周に装着されたパイプ状の解放操作部材６１を有している。解放操作部６１には、これを図１０の矢印方向に回転させた場合にロックピン３０を支持脚２２の長手方向下向きに移動させることができるように螺旋状に延びる案内手段としての螺旋孔６２が設けられている。なお、螺旋孔６２は、実際にはロックピン３０の両端部に一つずつ設けられているが、図示の都合上、手前側の一つのみが示されている。解放操作部材６１にはその長手方向に延びる複数の突出部６３が周方向に略等間隔で並べられて滑り止めとして設けられている。図１０の形態によれば、パイプ状の解放操作部材６１を支持脚の中心線ＣＬの回りに回転させることによりロックの解放が可能となるので他の形態と比較してスペース効率に優れている。 FIG. 10 is a perspective view showing another form of the release operation member different from the form of FIG. The embodiment shown in FIG. 10 has a pipe-like release operation member 61 mounted on the outer periphery of the support leg 22 so as to be rotatable around the center line CL of the support leg 22. The release operation portion 61 includes a spiral hole 62 as a guide means that extends spirally so that the lock pin 30 can be moved downward in the longitudinal direction of the support leg 22 when the release operation portion 61 is rotated in the direction of the arrow in FIG. Is provided. Note that one spiral hole 62 is actually provided at each end of the lock pin 30, but only one on the front side is shown for convenience of illustration. The release operation member 61 is provided with a plurality of protrusions 63 extending in the longitudinal direction thereof arranged in the circumferential direction at substantially equal intervals as a slip stopper. According to the form of FIG. 10, since the lock can be released by rotating the pipe-like release operation member 61 around the center line CL of the support leg, it is superior in space efficiency as compared with other forms. .

なお、本発明を実施する際には解放操作部材は必ずしも必要でない。従って、上記各形態に係る解放操作部材を省いた形態で本発明を実施することも可能である。また、ロック部材としては軸状のロックピンであることは必須ではなくロック部材の形状は任意である。ロック部材の移動方向が支持脚の長手方向に設定されていることは一例に過ぎない。例えば、図１１に示したように、支持脚２２の回転中心である軸線Ａｘの方向に関して支持脚２２に対する相対移動が許容されたロック部材６５と、ロック部材６５を付勢する付勢手段としてのコイルスプリング６６とを有するロック機構６４を備えた形態としてスタンド装置を実施することもできる。なお、図１１の形態の場合には、ロック部材６５の移動経路内の所定の位置に、例えばベース部２１の所定位置にロック壁６７が設けられていればよい。 In carrying out the present invention, the release operation member is not always necessary. Therefore, the present invention can be implemented in a form in which the release operation member according to each of the above forms is omitted. Further, the lock member is not necessarily a shaft-like lock pin, and the shape of the lock member is arbitrary. It is only an example that the movement direction of the lock member is set in the longitudinal direction of the support leg. For example, as shown in FIG. 11, the lock member 65 that is allowed to move relative to the support leg 22 in the direction of the axis Ax that is the center of rotation of the support leg 22, and the biasing means that biases the lock member 65. The stand device can also be implemented as a form provided with a lock mechanism 64 having a coil spring 66. In the case of the form of FIG. 11, the lock wall 67 may be provided at a predetermined position in the movement path of the lock member 65, for example, at a predetermined position of the base portion 21.

ロック部材が支持脚に対して相対移動可能な状態で設けられることは一例にすぎない。例えば、ロック部材が支持脚に対して相対移動不能に固定される形態として本発明を実施することもできる。図１２は図１１の形態とは異なるロック機構の他の形態を説明する説明図である。図１２のロック機構８０は、ロック部材としてのロックピン８１が支持脚２２に対して相対移動不能に固定されるとともに、支持脚２２が軸線Ａｘの回りに回転可能かつその長手方向に移動可能な状態でベース部２１に取り付けられている。支持脚２２には、支持軸２６が挿入可能な幅を持ちかつ長手方向に延びる長孔８２が形成されている。その長孔８２に支持軸２６が挿入されてその支持軸２６がベース部２１に固定されることにより、支持脚２２が軸線Ａｘの回りに回転可能かつ長手方向に移動可能な状態でベース部２１に取り付けられる。これにより、ロックピン８１が所定方向である長手方向に関してベース部２１に対する相対移動が可能な状態とされる。従って、支持脚２２を図１２の矢印で示した長手方向に直接動かすことにより、ロック機構８０のロックを解除することができる。ロック機構８０には、車体を立ち姿勢に保持している限り、図示の支持位置でロックピン８１とロック壁３５とが突き当たった状態に保持させる力が地面からの反力として加えられる。そのため、ロック機構８０に対して上述した付勢手段を敢えて設けなくてもロック機構としての機能は達成できる。従って、ロック機構８０は、構造の複雑化を回避できるとともに部品点数の削減に貢献できる。 It is merely an example that the lock member is provided in a state in which it can move relative to the support leg. For example, the present invention can be implemented as a configuration in which the lock member is fixed so as not to move relative to the support leg. FIG. 12 is an explanatory view for explaining another form of the locking mechanism different from the form of FIG. 12, the lock pin 81 as a lock member is fixed so as not to move relative to the support leg 22, and the support leg 22 can rotate around the axis Ax and move in the longitudinal direction thereof. It is attached to the base part 21 in a state. The support leg 22 is formed with a long hole 82 having a width into which the support shaft 26 can be inserted and extending in the longitudinal direction. The support shaft 26 is inserted into the long hole 82 and the support shaft 26 is fixed to the base portion 21, so that the support leg 22 can rotate around the axis Ax and move in the longitudinal direction. Attached to. As a result, the lock pin 81 can be moved relative to the base portion 21 in the longitudinal direction, which is a predetermined direction. Therefore, the lock of the lock mechanism 80 can be released by directly moving the support leg 22 in the longitudinal direction indicated by the arrow in FIG. As long as the vehicle body is held in a standing position, a force that keeps the lock pin 81 and the lock wall 35 in contact with each other at the illustrated support position is applied to the lock mechanism 80 as a reaction force from the ground. Therefore, the function as the lock mechanism can be achieved without intentionally providing the aforementioned urging means for the lock mechanism 80. Therefore, the lock mechanism 80 can avoid the complexity of the structure and contribute to the reduction of the number of parts.
