Description

折り畳み式ベビーカーの自立構造Folding stroller self-supporting structure
　この発明は、折り畳み式ベビーカーを自立させるための折り畳み式ベビーカーの自立構造に関し、より詳しくは、自立させたときの安定性が極めてよく、製造コストも抑えることができるような折り畳み式ベビーカーの自立構造に関する。 The present invention relates to a self-supporting structure of a foldable baby stroller for self-supporting a foldable baby stroller. About.
　折り畳み式ベビーカーの自立構造として、下記特許文献１に記載のものが提案されている。 As a self-supporting structure of a folding baby stroller, the one described in Patent Document 1 below has been proposed.
　これは、前輪を備えた左右の前脚部と、後輪を備えた左右の後脚部を有し、前脚部を上方に引き上げると左右幅方向に縮まって折り畳まれるベビーカーにおいて、折り畳む動作によってスタンドが自動的に出てきて自立するというものである。 This is a stroller that has left and right front legs with front wheels and left and right rear legs with rear wheels, and is folded in a lateral direction when the front legs are pulled upward. It comes out automatically and becomes independent.
　そのスタンドは、前記左右の後脚部に枢着されており、棒状をなして上端が後脚部に枢着される左右の腕部と、これら左右の腕部の下端を連結する支持部とを有する構造である。左右の腕部は、ベビーカーの使用時には左右方向に直線状にのびているが、ベビーカーを折り畳むとＶ字状に曲がって前記支持部が降下して１点で接地する。 The stand is pivotally attached to the left and right rear legs, and a left and right arm part having a rod shape and an upper end pivotally attached to the rear leg part, and a support part connecting the lower ends of the left and right arm parts, It is the structure which has. The left and right arms extend linearly in the left-right direction when the stroller is used, but when the stroller is folded, it bends in a V shape and the support part descends and contacts the ground at one point.
　左右の腕部の上端部は、左右の後脚部が相対的に近接する方向に折り畳まれる移動平面に沿って回動可能に軸支されている。 The upper ends of the left and right arms are pivotally supported along a moving plane that is folded in a direction in which the left and right rear legs are relatively close to each other.
　このような自立構造では、１個の後輪を１点と考えれば、２個の後輪と前記１個の支持部との合計３点で接地することになる。 In such a self-supporting structure, if one rear wheel is considered as one point, the grounding is made at a total of three points including the two rear wheels and the one support portion.
特許第４１４４７８６号公報Japanese Patent No. 4144786
　しかし、前記のように左右の腕部の上端部は、左右の後脚部が相対的に近接する方向に折り畳まれる移動平面に沿って回動可能に軸支されているので、前記支持部の位置は後輪に近い位置にある。 However, as described above, the upper end portions of the left and right arm portions are pivotally supported along a moving plane that is folded in a direction in which the left and right rear leg portions are relatively close to each other. The position is close to the rear wheel.
　そのうえ左右の腕部はそれぞれ後脚部に枢着され、これらの下端はさらに前記支持部に枢着されているので、２本の腕部も支持部も比較的自由に動く構造である。つまり支持部は、回転可能な腕部にぶら下がった状態であり、ガタガタして位置が定まらない。しかも、折り畳み時に上方へ引き上げた左右２個の前輪は後輪と同じ間隔で上方に存在するのにもかかわらず、前記のように３点で支持される。 Furthermore, since the left and right arm portions are pivotally attached to the rear leg portions, and the lower ends thereof are further pivotally attached to the support portion, the two arm portions and the support portion move relatively freely. That is, the support portion is in a state of being hung from the rotatable arm portion, and the position thereof is not determined by rattling. In addition, the two left and right front wheels lifted upward during folding are supported at three points as described above, although they exist upward at the same interval as the rear wheels.
　このため、自立状態は安定しにくく、些細な振動や軽い接触によって倒れてしまうことがある。 For this reason, the self-supporting state is difficult to stabilize and may fall down due to slight vibration or light contact.
　また、前記支持部が必要なぶん、部品点数が多くなって、製造コストがかさむ。 Also, the support part is necessary, and the number of parts is increased, which increases the manufacturing cost.
　そこで、この発明は、自立させたときの安定性を高め、製造コストも抑えることができるようにすることを主な課題とする。 Therefore, the main object of the present invention is to increase the stability when it is self-supporting and to suppress the manufacturing cost.
　そのための手段は、下端に後輪を備えた左右２本の後脚部を有し、これら後脚部をベビーカーの左右方向で互いに接近させると折り畳まれ、左右の後脚部に備えた支持脚部が接地して折り畳み状態のベビーカーを自立させる、折り畳み式ベビーカーの自立構造であって、前記支持脚部が、長手方向の中間部において互いに交差して該交差部において回転可能に連結された２本の支持脚担体で構成され、これら支持脚担体の上端部が、前記後脚部に対して、前後方向に傾いた状態で、左右の後脚部同士の接近と離反に伴って回転可能に枢着され、前記２本の支持脚担体における前記交差部よりも下の下端部が、ベビーカーを折り畳んで立てたときに前記後輪よりも前後方向に離れた位置でそれぞれ接地する接地部に設定された折り畳み式ベビーカーの自立構造である。 The means for this purpose has two left and right rear leg portions with rear wheels at the lower end, and is folded when the rear leg portions approach each other in the left and right direction of the stroller, and the support legs provided on the left and right rear leg portions 2 is a self-supporting structure of a foldable baby stroller in which a part is grounded and self-supports a folded baby stroller, wherein the support leg portions intersect each other at a middle portion in the longitudinal direction and are rotatably connected at the intersecting portion. The support leg carrier is composed of a book, and the upper end portions of the support leg carriers are tilted in the front-rear direction with respect to the rear leg portion, and can be rotated as the left and right rear leg portions approach and separate from each other. The lower end of the two support leg carriers below the intersection is set as a grounding portion that is grounded at a position farther in the front-rear direction than the rear wheel when the stroller is folded and stood. Foldable baby It is a self-supporting structure of the car.
　この構成によれば、折り畳み前は角度が大きく開いていた支持脚部が、ベビーカーを折り畳む動作を行うと左右の後脚部同士の接近に伴って開き角度を小さくする方向に回転する。この回転は長手方向の中間部の交差部において行われ、上端部が後脚部に枢着された支持脚部は、交差部よりも下端側の接地部を下方に突き出すように伸びて、折り畳まれたベビーカーを自立させる姿勢で接地部が接地して、後輪を含めて少なくとも４点で支える。しかも、支持脚部の接地部は、前記後輪よりも前後方向に離れた位置において間隔を隔てた少なくとも２点で接地する。 According to this configuration, the support leg that has been opened at a large angle before folding is rotated in a direction to reduce the opening angle with the approach of the left and right rear legs when the stroller is folded. This rotation is performed at the intersection of the middle part in the longitudinal direction, and the support leg whose upper end is pivotally attached to the rear leg extends and folds so that the grounding part on the lower end side protrudes downward from the intersection. The grounding unit touches the stroller so that it can stand on its own, and supports it with at least four points including the rear wheel. In addition, the grounding portions of the support legs are grounded at at least two points spaced from each other at positions farther in the front-rear direction than the rear wheels.
　この発明によれば、後輪のほかに左右方向に離れた少なくとも２個の接地部が後輪から前後方向に離れた位置で接地するので、自立させたときの安定性を高めることができる。また、部品点数を抑えることができるので、製造コストの低減も可能である。 According to the present invention, since at least two grounding portions separated in the left-right direction in addition to the rear wheels are grounded at positions separated from the rear wheels in the front-rear direction, it is possible to improve the stability when being independent. Further, since the number of parts can be suppressed, the manufacturing cost can be reduced.

FIG. 1 is a perspective view of a state in which a foldable stroller 11 (hereinafter referred to as “heavy car”; only the frame is shown for convenience) is folded and self-supported, and FIG. 2 is a perspective view of the stroller 11 before folding. FIG.
　これらの図に示すようにベビーカー１１は、下端に後輪１２を備えた左右２本の後脚部１３と、下端に前輪１４を備えた左右２本の前脚部１５を有し、前脚部１５を上方に引き起こすと前脚部１５と後脚部１３がそれぞれ左右方向で互いに接近し、縦に細長いステッキ状に折り畳まれる構造である。そして、この形態で自立可能にするために後脚部１３には支持脚部２１が回転可能に枢着されている。 As shown in these drawings, the stroller 11 has two left and right rear leg portions 13 having a rear wheel 12 at the lower end and two left and right front leg portions 15 having a front wheel 14 at the lower end. When the heel is raised upward, the front leg portion 15 and the rear leg portion 13 approach each other in the left-right direction, and are folded into a vertically long stick shape. And in order to be able to stand by this form, the support leg part 21 is pivotally attached to the rear leg part 13 so that rotation is possible.
　支持脚部２１は折り畳み動作に伴って自動的に下方に突き出す構造であり、ベビーカー１１を立てた姿勢で前記後輪１２ととともに接地して、細長いベビーカー１１を支える。 The support leg portion 21 has a structure that automatically protrudes downward in accordance with the folding operation, and supports the elongated baby stroller 11 by being grounded with the rear wheel 12 in a posture in which the baby stroller 11 is stood.
　すなわち、前記支持脚部２１は、適宜長さの棒状をなす２本の支持脚担体２２で構成されている。これら支持脚担体２２は長手方向の中間部において互いに交差し、この交差部２３が回転可能に連結されて一体となっている。 That is, the support leg portion 21 is composed of two support leg carriers 22 each having a rod shape with an appropriate length. These support leg carriers 22 intersect with each other at an intermediate portion in the longitudinal direction, and the intersecting portion 23 is rotatably connected and integrated.
　具体的には、支持脚担体２２は直線状に延びる丸パイプで構成され、前記交差部２３における相対向面には平坦面２３ａが形成されている。そして、この交差部２３がリベット等の枢着軸２４によって回転可能に連結される。このため支持脚部２１は、全体としてＸ字形をなし、枢着軸２４を中心に相対回転する構造である。 Specifically, the support leg carrier 22 is formed of a round pipe extending linearly, and a flat surface 23 a is formed on the opposing surface of the intersecting portion 23. The intersecting portion 23 is rotatably connected by a pivot shaft 24 such as a rivet. For this reason, the support leg 21 has an X-shape as a whole, and has a structure that rotates relative to the pivot shaft 24.
　前記後脚部１３に対しては支持脚担体２２の上端部２２ａが枢着される。枢着は後脚部１３に直接行ってもよいが、図３、図４に示したような取り付け部材２５を介して行うのがよい。各支持脚担体２２の下端部は、前記後輪１２よりも前後方向に離れた位置でそれぞれ接地する接地部２２ｂである。具体的には例えば、上方に跳ね上げられた前輪１４と同程度に離れた位置に接地するように設定するとよい。この接地部２２ｂは丸パイプを長手方向と直交する方向に単に切断した形状に形成されている。 The upper end portion 22a of the support leg carrier 22 is pivotally attached to the rear leg portion 13. The pivoting may be performed directly on the rear leg 13 but may be performed via the attachment member 25 as shown in FIGS. The lower end portion of each support leg carrier 22 is a grounding portion 22b for grounding at a position farther in the front-rear direction than the rear wheel 12. Specifically, for example, it may be set so as to be grounded at a position as far away from the front wheel 14 that is flipped upward. The grounding portion 22b is formed in a shape obtained by simply cutting a round pipe in a direction perpendicular to the longitudinal direction.
　前記取り付け部材２５は、支持脚部２１を後脚部１３に対して前後方向に傾けて取付けるためのもので、後脚部１３に固定される固定部２６と、支持脚担体２２の上端部２２ａを枢着保持する保持部２７を有する。前記固定部２６は、後脚部１３の断面形状に合わせて後脚部１３を掴むような形状に形成される。 The attachment member 25 is for attaching the support leg 21 to the rear leg 13 by tilting in the front-rear direction. The fixing member 26 is fixed to the rear leg 13 and the upper end 22 a of the support leg carrier 22. Has a holding portion 27 for pivotally holding. The fixing portion 26 is formed in a shape that grips the rear leg portion 13 according to the cross-sectional shape of the rear leg portion 13.
　図３、図４の例では、後脚部１３が前後方向に長い断面略小判形状であるため、固定部２６は断面略Ｃ字形に形成される。すなわち固定部２６は、後脚部１３の前後両端面に当接する前面部２６ａと後面部２６ｂと、後脚部１３の内側面に当接する内側面部２６ｃを有する。後脚部１３に対しては、前面部２６ａと後面部２６ｂを貫通するリベット等の固定具２８によって一体化される。 3 and 4, since the rear leg portion 13 has a substantially oval cross section that is long in the front-rear direction, the fixing portion 26 is formed in a substantially C-shaped cross section. That is, the fixed portion 26 includes a front surface portion 26 a and a rear surface portion 26 b that contact the front and rear end surfaces of the rear leg portion 13, and an inner side surface portion 26 c that contacts the inner surface of the rear leg portion 13. The rear leg portion 13 is integrated by a fixture 28 such as a rivet that penetrates the front surface portion 26a and the rear surface portion 26b.
　後脚部１３が丸パイプからなる場合には、前記固定部２６は、図５に示したように例えば断面円形であるとよく、前記と同様にリベット等の固定部２８で回転不可に一体化するとよい。 In the case where the rear leg portion 13 is formed of a round pipe, the fixing portion 26 may be, for example, circular in cross section as shown in FIG. 5 and integrated with the fixing portion 28 such as a rivet so that it cannot rotate. Good.
　前記保持部２７は、固定部２６の内側面部２６ｃから内側に向けて突設される２枚の保持片２９からなる。これらは支持脚担体２２を挟む間隔を隔てて設けられており、各保持片２９の面方向が、後脚部１３の長手方向から前方斜め下に向くように設けられる。これは、前脚部１５を跳ね上げた姿勢に折り畳む上に、後輪１２が後脚部１３の後側に偏って設けられているからである。保持片２９の角度は、前記固定部２６の固定位置や接地部２２ｂの所望する接地位置などに応じて適宜に定められるが、例えば３０度前後であるとよい。 The holding portion 27 includes two holding pieces 29 that protrude inward from the inner side surface portion 26c of the fixing portion 26. These are provided at an interval between which the support leg carrier 22 is sandwiched, and are provided so that the surface direction of each holding piece 29 is directed obliquely forward and downward from the longitudinal direction of the rear leg portion 13. This is because the front wheel 15 is folded up in a posture in which the front leg 15 is flipped up, and the rear wheel 12 is provided biased to the rear side of the rear leg 13. The angle of the holding piece 29 is appropriately determined according to the fixing position of the fixing portion 26, the desired grounding position of the grounding portion 22b, and the like, for example, is preferably about 30 degrees.
　このような保持部２７に対して支持脚担体２２の上端部２２ａがリベット等の枢着軸３０で回転可能に一体化される。前記保持部２７に保持された支持脚担体２２はそれぞれ前方内側斜め下に向けて延びて、中間部で交差してＸ字形を形成する。 The upper end portion 22a of the support leg carrier 22 is integrated with the holding portion 27 so as to be rotatable by a pivot shaft 30 such as a rivet. The supporting leg carriers 22 held by the holding portion 27 extend obliquely downward toward the front inner side, and intersect each other at an intermediate portion to form an X shape.
　前記のような取り付け部材２５を用いるので、後脚部１３自体に特別な加工を施さなくても支持脚部２１を後脚部１３に対して所望の向きに枢着することが容易に行える。 Since the mounting member 25 as described above is used, the support leg 21 can be easily pivotally attached to the rear leg 13 in a desired direction without special processing on the rear leg 13 itself.
　このように構成されたベビーカー１１では、折り畳み前の支持脚部２１は、図６に仮想線で示したように、左右方向に広がっている左右の後脚部１３に引っ張られて左右方向に長い形態になっている。支持脚部２１が後脚部１３に対して前方斜め下に向けられていることと相俟って、支持脚部２１は後輪１２に接触せず、走行など使用に際して一切の支障がない状態である。 In the stroller 11 configured as described above, the support leg 21 before being folded is pulled by the left and right rear leg parts 13 extending in the left-right direction as shown in phantom lines in FIG. It is in form. In combination with the support leg 21 being directed obliquely downward and forward with respect to the rear leg part 13, the support leg part 21 does not contact the rear wheel 12, and there is no trouble in use such as running. It is.
　前記ベビーカー１１を折り畳むべく前脚部１５を上方へ引き起こすと左右の前脚部１５と後脚部１３がそれぞれ左右方向で互いに接近して、ベビーカー１１は折り畳まれる。この折り畳み動作に伴って支持脚部２１は、支持脚担体２２の上端部２２ａと交差部２３において回転する。この回転により、支持脚部２１は縦方向に長い形態に変形し、交差部２３とともに下端の接地部２２ｂが下方に向かって突き出て、図６に実線で示したように、間隔が狭まった後輪１２とともに接地部２２ｂが接地して、細長いステッキ状の形態に折り畳まれたヘビーカー１１を立てた状態に支える。 When the front leg portion 15 is raised upward to fold the stroller 11, the left and right front leg portions 15 and the rear leg portion 13 approach each other in the left-right direction, and the stroller 11 is folded. With this folding operation, the support leg 21 rotates at the upper end 22 a and the intersection 23 of the support leg carrier 22. By this rotation, the support leg portion 21 is deformed into a shape that is long in the vertical direction, and the ground contact portion 22b at the lower end protrudes downward together with the intersecting portion 23, and as shown by the solid line in FIG. The grounding portion 22b is grounded together with the wheel 12, and supports the heavy car 11 folded into an elongated stick shape.
　このとき、接地部２２ｂは後輪１２よりも前方向に離れた位置で接地するうえに、支持脚部２１の２個の接地部２２ｂは左右方向に間隔を隔てて２点で接地する。 At this time, the grounding portion 22b is grounded at a position farther forward than the rear wheel 12, and the two grounding portions 22b of the support leg portion 21 are grounded at two points with an interval in the left-right direction.
　前記のように支持脚部２１は後脚部１３に対して斜めに取り付けられているので、接地部２２ｂが接地する位置は、各部の寸法にもよるが、後輪１２から前方に比較的はなれた位置となる。 As described above, since the support leg portion 21 is attached obliquely to the rear leg portion 13, the position where the grounding portion 22b contacts the ground is relatively far from the rear wheel 12 depending on the size of each portion. It becomes the position.
　このため、支持脚部２１による支持状態は安定している。この結果、折り畳んだベビーカー１１を例えば電車等に載せた場合でも自立状態を保つことができ、予期しない接触によって簡単に倒れてしまうような事態も回避できるようになる。 For this reason, the support state by the support leg 21 is stable. As a result, even when the folded stroller 11 is placed on a train or the like, for example, it is possible to maintain a self-supporting state, and it is possible to avoid a situation in which the baby stroller 11 falls easily due to an unexpected contact.
　また、支持脚部２１を構成する支持脚担体２２は丸パイプで構成されているので、接地部２２ｂは線材を用いて構成した場合に比して強度が高く、特別の加工をせずとも安定した接地状態が得られるものとなる。 Further, since the support leg carrier 22 constituting the support leg portion 21 is constituted by a round pipe, the grounding portion 22b has a higher strength than that constituted by using a wire rod, and is stable without special processing. A grounded state can be obtained.
　さらに、前記支持脚担体２２は後脚部１３に対して枢着されているものの、各支持脚担体２２が互いに枢着されているので、３点で支えられ、どのような開き角度のときでも安定した形態になる。このように、従来の自立構造とは異なってガタガタする要素はない。この結果、走行中や折り畳み動作中に雑音が生じる不都合を回避できる。そのうえ、部品点数を少なくできるので、製造コストの低減も可能である。 Further, although the support leg carrier 22 is pivotally attached to the rear leg portion 13, each support leg carrier 22 is pivotally attached to each other, so that it is supported at three points and can be opened at any opening angle. It becomes a stable form. Thus, unlike the conventional self-supporting structure, there is no rattling element. As a result, it is possible to avoid the inconvenience that noise occurs during traveling and folding operations. In addition, since the number of parts can be reduced, the manufacturing cost can be reduced.
　図７は前記支持脚担体２２の接地部２２ｂの他の例を示す側面図である。図７（ａ）に示すようにゴム等からなるすべり止め部材３１を取付けてもよい。また図７（ｂ）に示したように、接地部２２ｂがより広い面で接地するように、接地部２２ｂの下端面を傾斜面で形成してもよい。図７（ｃ）は下端部を下に向けて折曲した接地部２２ｂの例を示し、接地時に接地部２２ｂの下端部が垂直に立つようにする。図７（ｄ）は接地部２２ｂを前後に枝分かれさせてそれぞれの支持脚担体２２において２点で接地するようにした例である。このような接地部２２ｂを設けることで、１個の後輪を１点と考えたときに、合計６点で接地するようになる。 FIG. 7 is a side view showing another example of the ground contact portion 22b of the support leg carrier 22. As shown in FIG. As shown in FIG. 7A, a non-slip member 31 made of rubber or the like may be attached. Further, as shown in FIG. 7B, the lower end surface of the ground portion 22b may be formed as an inclined surface so that the ground portion 22b is grounded on a wider surface. FIG. 7C shows an example of the grounding portion 22b bent with the lower end portion facing downward, and the lower end portion of the grounding portion 22b stands vertically during grounding. FIG. 7D shows an example in which the grounding portion 22b is branched forward and backward so that the respective support leg carriers 22 are grounded at two points. By providing such a grounding portion 22b, when one rear wheel is considered as one point, the grounding is made at a total of six points.
　図８は支持脚部２１の他の例を示す分解状態の正面図であり、この支持脚部２１は、前記取り付け部材２５を有する一対の上部材２１ａと、前記枢着軸２４を有する下部材２１ｂとの２種類の部材で構成されている。 FIG. 8 is an exploded front view showing another example of the support leg 21, and the support leg 21 includes a pair of upper members 21 a having the attachment members 25 and a lower member having the pivot shaft 24. It is comprised by two types of members with 21b.
　すなわち、上部材２１ａは、支持脚担体上部２２ｃと、これを枢着する前記取り付け部材２５で構成され、これは後脚部１３に対して一体に固定されている。下部材２１ｂは、２本の支持脚担体下部２２ｄで構成され、これらの交差部２３は枢着軸２４で枢着されてＸ字状に構成されている。一方の支持脚担体下部２２ｄの上端には、厚み方向に貫通する貫通穴２２ｅが形成され、一方の上部材２１ａの支持脚担体上部２２ｃの下端には、外周方向に付勢された状態で固定された突起２２ｆが設けられ、下部材２１ｂを上部材２１ａに嵌め込むと抜け止めがなされる構造である。 That is, the upper member 21a is composed of a support leg carrier upper part 22c and the mounting member 25 pivotally attached thereto, which is integrally fixed to the rear leg part 13. The lower member 21b is composed of two support leg carrier lower portions 22d, and these intersecting portions 23 are pivotally mounted on a pivot shaft 24 and configured in an X shape. A through hole 22e penetrating in the thickness direction is formed at the upper end of one support leg carrier lower portion 22d, and fixed to the lower end of the support leg carrier upper portion 22c of one upper member 21a while being biased in the outer peripheral direction. The protrusion 22f is provided, and the lower member 21b is prevented from coming off when the lower member 21b is fitted into the upper member 21a.
　このように構成された支持脚部２１を備えたベビーカー１１では、梱包時には下部材２１ｂを上部材２１ａから分離しておくと、下部材２１ｂの突出がなくなって、コンパクトに箱詰めできる。このため、輸送コストや管理コストが嵩むことを防止できる。支持脚部２１が輸送中に不測に損傷してしまうようなことも回避できる。また下部材２１ｂは上部材２１ａに差し込むだけで結合一体化できるので、作業は容易である。 In the stroller 11 having the support leg 21 configured as described above, if the lower member 21b is separated from the upper member 21a at the time of packing, the lower member 21b does not protrude and can be packed compactly. For this reason, it can prevent that transportation cost and management cost increase. It can also be avoided that the support leg 21 is unexpectedly damaged during transportation. Further, since the lower member 21b can be combined and integrated simply by being inserted into the upper member 21a, the operation is easy.
　図９、図１０は支持脚部２１の他の例を示している。先の例では、支持脚担体２２の上端部２２ａを枢着する保持部２７が固定部２６の内側（内側面部２６ｃ）、つまり後脚部１３の内側に形成されていた。これに対して、図９、図１０の例では、後脚部１３よりも前後方向に迫り出した状態で形成されている。 9 and 10 show other examples of the support leg 21. FIG. In the previous example, the holding portion 27 for pivotally attaching the upper end portion 22 a of the support leg carrier 22 is formed inside the fixing portion 26 (inner side surface portion 26 c), that is, inside the rear leg portion 13. On the other hand, in the example of FIG. 9, FIG. 10, it forms in the state which protruded from the back leg part 13 in the front-back direction.
　具体的には支持脚部２１が傾く方向と同じ前方に向けて、保持部２７が突設されている。保持片２９等は前記と同様である。但し、図１０に示したように、保持部２７が固定部２６よりも前に迫り出しているので、支持脚担体の２２の上端部２２ａは、保持部２７を後脚部１３の内側に位置させたときよりも前方に位置することになる。このため、保持片２９の角度を先の例の場合よりも小さく設定している。 Specifically, a holding portion 27 is provided so as to project forward in the same direction as the direction in which the support leg portion 21 is inclined. The holding piece 29 and the like are the same as described above. However, as shown in FIG. 10, since the holding portion 27 protrudes ahead of the fixing portion 26, the upper end portion 22 a of the support leg carrier 22 positions the holding portion 27 inside the rear leg portion 13. It will be located in front of when you let it. For this reason, the angle of the holding piece 29 is set smaller than in the case of the previous example.
　このようにしても支持脚部２１が後輪１２に接することはなく、荷重を支持するに適した角度を重視して設計ができる。また、支持脚部２１の長さを短くすることもできる。 Even in this case, the support leg 21 does not contact the rear wheel 12, and the design can be made with an emphasis on an angle suitable for supporting the load. Further, the length of the support leg 21 can be shortened.
　この発明の構成と、前記一形態の構成との対応において、　
この発明の支持脚担体は、前記支持脚担体２２、支持脚担体上部２１ｃと支持脚担体下部２１ｄに対応するも、

The present invention is not limited to the above-described configuration, and other configurations can be adopted.
　例えば、支持脚担体は全体的に直線状に形成せずに、湾曲部分を適宜有する形状であってもよい。 For example, the support leg carrier may not have a linear shape as a whole but may have a curved portion as appropriate.
　また、支持脚担体の突出方向は、ベビーカーの形態によっては、前記のように前方ではなく後方であってもよい。 Further, the protruding direction of the support leg carrier may be not the front but the rear as described above depending on the form of the stroller.
　さらに、この発明の自立構造は前脚部を上方へ引き起こさずに折り畳むベビーカーに採用することもできる。 Furthermore, the self-supporting structure of the present invention can also be used in a stroller that folds without causing the front legs to rise upward.
