また、座席本体２０には、子供用ベルト３０が設けられている。図３に示す例では、子供用ベルト３０は、股ベルト、腰ベルトおよび肩ベルトを有する五点式ベルトとして形成されているが、これに限られない。例えば、子供用ベルト３０は、股ベルトおよび肩ベルトを有する三点式ベルトとして形成されてもよい。 Also, the seat body 20 is provided with a child belt 30 . In the example shown in FIG. 3, the child belt 30 is formed as a five-point belt having a crotch belt, a waist belt and a shoulder belt, but is not limited to this. For example, child belt 30 may be formed as a three-point belt having a crotch belt and a shoulder belt.
図３および図６によく示されているように、子供用ベルト３０は、第１ベルト部材３１と、第２ベルト部材３２と、を有している。第１ベルト部材３１は、股ベルトとして機能する。第２ベルト部材３２は、肩ベルト３２ａ及び腰ベルト３２ｂとして機能する。第１ベルト部材３１は、座面部２１の略中央に一端を固定されている。第１ベルト部材３１の他端には、バックル３３が取り付けられている。また、第１ベルト部材３１には、ベルトカバー３４が設けられている。一方、第２ベルト部材３２は、幅方向Ｄ１に離間して一対設けられている。各第２ベルト部材３２はタング３５を通過して延びており、タング３５で折り返されることによって、肩ベルト３２ａ及び腰ベルト３２ｂが画成される。第２ベルト部材３２の腰ベルト３２ｂ側の端部は、座面部２１に固定されている。一対の第２ベルト部材３２は、座面部２１内を通過して、座席本体２０のうちの座面部２１と後壁部２２との接続位置を含む腰区域２４内の幅方向両端部に位置する一対の端領域２４ａから、それぞれ延び出ている。第２ベルト部材３２の肩ベルト３２ａ側の端部は、後壁部２２に設けられた子供用ベルト穴を通過して、後壁部２２内に配置されている。そして、後壁部２２内で、ベルト長調節部材３６の一端に接続されている。ベルト長調節部材３６は、座面部２１に設けられた子供用ベルト穴を通過して、その他端がベルトカバー３４に接続されている。 As best shown in FIGS. 3 and 6, child belt 30 has first belt member 31 and second belt member 32 . The first belt member 31 functions as a crotch belt. The second belt member 32 functions as a shoulder belt 32a and a waist belt 32b. One end of the first belt member 31 is fixed to substantially the center of the seat surface portion 21 . A buckle 33 is attached to the other end of the first belt member 31 . A belt cover 34 is provided on the first belt member 31 . On the other hand, a pair of second belt members 32 are provided spaced apart in the width direction D1. Each second belt member 32 extends past a tongue 35 where it is folded back to define a shoulder belt 32a and a waist belt 32b. The end portion of the second belt member 32 on the waist belt 32b side is fixed to the seat surface portion 21 . The pair of second belt members 32 pass through the seat surface portion 21 and extend from a pair of end regions 24a located at both ends in the width direction in the waist region 24 including the connection position between the seat surface portion 21 and the rear wall portion 22 of the seat body 20. The end portion of the second belt member 32 on the side of the shoulder belt 32 a passes through a child belt hole provided in the rear wall portion 22 and is arranged inside the rear wall portion 22 . Then, it is connected to one end of the belt length adjusting member 36 within the rear wall portion 22 . The belt length adjusting member 36 passes through a child belt hole provided in the seat portion 21 and is connected to the belt cover 34 at the other end.
このような子供用ベルト３０を用いる場合、まず、幼児座席１０に子供を着座させ、タング３５をバックル３３で係止する。次に、ベルト長調節部材３６を引っ張って、腰ベルト３２ｂ及び肩ベルト３２ａの長さを調節する。このようにして、子供用ベルト３０によって、幼児座席１０に着座した子供を幼児座席１０に固定することができる。なお、ベルト長調節部材３６は、座面部２１内で、図示しない固定装置によって固定されている。この固定装置によって、意図せずベルト長調節部材３６が座面部２１および後壁部２２内に引き込まれて腰ベルト３２ｂ及び肩ベルト３２ａが緩むことが防止されている。 When using such a child belt 30 , first, a child is seated on the infant seat 10 and the tongue 35 is locked with the buckle 33 . Next, the belt length adjusting member 36 is pulled to adjust the length of the waist belt 32b and the shoulder belt 32a. In this manner, a child seated on the infant seat 10 can be secured to the infant seat 10 by the child belt 30 . The belt length adjusting member 36 is fixed inside the seat surface portion 21 by a fixing device (not shown). This fixing device prevents the belt length adjusting member 36 from being unintentionally drawn into the seat surface portion 21 and the rear wall portion 22, thereby loosening the waist belt 32b and the shoulder belt 32a.
次に、握り部材５０について説明する。握り部材５０は、握り部材５０の一側端部をなす一側接続部５１と、他側端部をなす他側接続部５２と、一側接続部５１および他側接続部５２を接続する中間部５３と、を有する。中間部５３は湾曲しており、握り部材５０は、全体としてＵ字状をなす。したがって、握り部材５０の軸線５０ｘは、Ｕ字状に延びている。握り部材５０の一側接続部５１および他側接続部５２は、握り部材５０のＵ字の両端に相当する部分である。一側接続部５１は、一側側壁部２５に設けられた一側端部支持部材４１に接続する。また、他側接続部５２は、他側側壁部２６に設けられた他側端部支持部材４２に接続する。図３に示すように、一側側壁部２５が一側端部支持部材４１に接続した状態において、中間部５３は、座面部２１の上方を幼児座席１０の幅方向に沿って延びている。 Next, the grip member 50 will be described. The grip member 50 has a one-side connection portion 51 forming one side end portion of the grip member 50, the other-side connection portion 52 forming the other-side end portion, and an intermediate portion 53 connecting the one-side connection portion 51 and the other-side connection portion 52. The intermediate portion 53 is curved, and the grip member 50 has a U shape as a whole. Therefore, the axis 50x of the grip member 50 extends in a U shape. The one-side connection portion 51 and the other-side connection portion 52 of the grip member 50 are portions corresponding to both ends of the U-shape of the grip member 50 . The one-side connection portion 51 connects to the one-side end support member 41 provided on the one-side side wall portion 25 . Further, the other-side connecting portion 52 is connected to the other-side end support member 42 provided on the other-side side wall portion 26 . As shown in FIG. 3 , the intermediate portion 53 extends along the width direction of the infant seat 10 above the seat surface portion 21 when the one side wall portion 25 is connected to the one side end support member 41 .
図４によく示されているように、一側接続部５１は、一側端部支持部材４１に接続した状態において、一側側壁部２５から上方に延び出している。また、図５によく示されているように、他側接続部５２は、他側端部支持部材４２に接続した状態において、他側側壁部２６から上方に延び出している。これにより、握り部材５０の中間部５３と座席本体２０の座面部２１との間に、広い空間が確保される。図示された例では、一側接続部５１および他側接続部５２は、側面視において、対応する側の側壁部２５，２６の上縁２５ａ，２６ａに垂直な方向（より具体的には、側面視における、側壁部２５，２６の上縁２５ａ，２６ａのうち端部支持部材４１，４２が接続された部分の接線Ｌに垂直な方向）に対してなす角度が１０°以下となる方向Ｄ１に延び出している。 As best shown in FIG. 4 , the one-side connection portion 51 extends upward from the one-side side wall portion 25 when connected to the one-side end support member 41 . 5, the other side connecting portion 52 extends upward from the other side wall portion 26 when connected to the other side end support member 42. As shown in FIG. Thereby, a wide space is secured between the intermediate portion 53 of the grip member 50 and the seat surface portion 21 of the seat body 20 . In the illustrated example, the one-side connection portion 51 and the other-side connection portion 52 extend in a direction D1 forming an angle of 10° or less with respect to a direction perpendicular to the upper edges 25a and 26a of the side wall portions 25 and 26 on the corresponding side (more specifically, a direction perpendicular to the tangential line L of the portion of the upper edges 25a and 26a of the side wall portions 25 and 26 to which the end support members 41 and 42 are connected, as seen from the side).
なお、本実施の形態の握り部材５０は、幼児を幼児座席１０に乗せ降ろしし易いよう、必要に応じて座面部２１の上方から移動させることができるようになっている。さらに、握り部材５０を移動させる際、座席本体２０から取り外された握り部材５０の端部が幼児座席１０に着座する幼児に接触する虞が低減されるよう、握り部材５０の上記端部が座面部２１の上方を通過することがないようになっている。 In addition, the grip member 50 of the present embodiment can be moved from above the seat surface portion 21 as needed so that the infant can be easily put on and off the infant seat 10 . Further, when moving the grip member 50, the end of the grip member 50 is prevented from passing above the seat surface part 21 so that the end of the grip member 50 detached from the seat body 20 is less likely to come into contact with the infant seated on the infant seat 10.例文帳に追加
具体的には、図３および図６から理解されるように、握り部材５０の一側接続部５１は、一側端部支持部材４１に着脱可能に接続している。また、握り部材５０の他側接続部５２は、他側端部支持部材４２に対して回転可能に接続している。したがって、握り部材５０の一側接続部５１を一側端部支持部材４１から取り外し、他側接続部５２を他側端部支持部材４２に対して回転させることにより、握り部材５０を、座面部２１の上方から座面部２１の側方へ移動させることができる。握り部材５０は、他側接続部５２が他側側壁部２６から延び出す方向Ｄ１に沿った回転軸線（したがって、他側接続部５２における握り部材５０の軸線５０ｘに沿った回転軸線）を中心として回転する。したがって、一側端部支持部材４１から取り外された一側接続部５１は、座面部２１の上方を通過することなく、座面部２１の周囲を通過する。また、握り部材５０が座席本体２０の周壁部２８の上縁２８ａによって画成される面に沿って移動するので、握り部材５０が幼児座席１０の周囲に位置するものと干渉する虞が低減される。 Specifically, as understood from FIGS. 3 and 6, the one-side connection portion 51 of the grip member 50 is detachably connected to the one-side end support member 41 . The other side connection portion 52 of the grip member 50 is rotatably connected to the other side end support member 42 . Therefore, by removing the one-side connection portion 51 of the grip member 50 from the one-side end support member 41 and rotating the other-side connection portion 52 with respect to the other-side end support member 42, the grip member 50 can be moved from above the seat surface portion 21 to the side of the seat surface portion 21. The grip member 50 rotates about the rotation axis along the direction D1 in which the other connection portion 52 extends from the other side wall portion 26 (therefore, the rotation axis along the axis 50x of the grip member 50 at the other connection portion 52). Therefore, the one-side connecting portion 51 removed from the one-side end support member 41 passes around the seat surface portion 21 without passing over the seat surface portion 21 . In addition, since the grip member 50 moves along the plane defined by the upper edge 28a of the peripheral wall portion 28 of the seat body 20, the possibility of the grip member 50 interfering with the surroundings of the infant seat 10 is reduced.
図３～図８を参照して、握り部材５０と一対の端部支持部材４１，４２について、さらに詳細に説明する。図７は、一側端部支持部材４１の斜視図であり、図８は、一側接続部５１の斜視図である。 3-8, the grip member 50 and the pair of end support members 41, 42 will be described in greater detail. 7 is a perspective view of the one-side end support member 41, and FIG. 8 is a perspective view of the one-side connection portion 51. FIG.
まず、図５を参照して、他側接続部５２および他側端部支持部材４２について説明する。 First, the other-side connecting portion 52 and the other-side end support member 42 will be described with reference to FIG.
他側端部支持部材４２は、他側側壁部２６に固定される基部４２ａと、基部４２ａから上方に突出した円柱状の軸凸部４２ｂとを有する。図示された例では、軸凸部４２ｂは、側面視において、上述した他側接続部５２が延び出す方向Ｄ１（側面視において、他側側壁部２６の上縁２６ａに垂直な方向に対してなす角度が１０°以下となる方向Ｄ１）に延び出している。 The other-side end support member 42 has a base portion 42a fixed to the other-side side wall portion 26, and a columnar shaft projection portion 42b projecting upward from the base portion 42a. In the illustrated example, the shaft convex portion 42b extends in a direction D1 in which the other-side connecting portion 52 extends in a side view (a direction D1 in which the angle formed with the direction perpendicular to the upper edge 26a of the other-side side wall portion 26 is 10° or less in a side view).
握り部材５０の他側接続部５２には、軸凸部４２ｂを収容する軸受凹部５２ａが設けられている。そして、他側接続部５０は、軸凸部４２ｂの周りを回転することができる。軸受凹部５２ａは、他側端部５２の延びる方向Ｄ１に沿って延びている。これにより、握り部材５０は、他側端部５２における握り部材５０の軸線５０ｘに沿った回転軸線を中心として回転することができる。なお、図示された例では、他側接続部５２と他側端部支持部材４２とは、着脱不能に接続されている。 The other side connection portion 52 of the grip member 50 is provided with a bearing concave portion 52a that accommodates the shaft convex portion 42b. Then, the other-side connecting portion 50 can rotate around the shaft convex portion 42b. The bearing recessed portion 52a extends along the direction D1 in which the other side end portion 52 extends. Thereby, the grip member 50 can be rotated around the rotation axis along the axis 50 x of the grip member 50 at the other end 52 . In addition, in the illustrated example, the other-side connecting portion 52 and the other-side end support member 42 are non-detachably connected.
次に、中間部５３について説明する。中間部５３は、弾性変形可能に形成されている。中間部５３を弾性変形させることにより、他側接続部５２を他側端部支持部材４２に接続したまま、一側接続部５１を、一側端部支持部材４１に上方から接近するように、あるいは一側端部支持部材４１から上方に離間するように移動させることができる。中間部５３は、例えば、エチレン酢酸ビニルコポリマー等の樹脂で形成されている。 Next, the intermediate portion 53 will be described. The intermediate portion 53 is formed to be elastically deformable. By elastically deforming the intermediate portion 53, the one-side connection portion 51 can be moved to approach the one-side end support member 41 from above or away from the one-side end support member 41 while the other-side connection portion 52 remains connected to the other-side end support member 42. The intermediate portion 53 is made of resin such as ethylene-vinyl acetate copolymer, for example.
次に、図４および図７～図８を参照して、一側接続部５１および一側端部支持部材４１について説明する。 Next, the one-side connection portion 51 and the one-side end support member 41 will be described with reference to FIGS. 4 and 7 to 8. FIG.
図４および図７に示すように、一側端部支持部材４１は、一側側壁部２５に固定される基部４１ａと、基部４１ａから上方に突出した保持凸部４１ｂとを有する。図示された例では、保持凸部４１ｂは、円柱状に形成されている。図４に示すように、保持凸部４１ｂは、上述した一側接続部５１が延び出す方向Ｄ１（側面視において、一側側壁部２５の上縁２５ａに垂直な方向に対してなす角度が１０°以下となる方向Ｄ１）に突出している。 As shown in FIGS. 4 and 7, the one-side end support member 41 has a base portion 41a fixed to the one-side side wall portion 25 and a holding convex portion 41b projecting upward from the base portion 41a. In the illustrated example, the holding protrusion 41b is formed in a cylindrical shape. As shown in FIG. 4, the holding convex portion 41b protrudes in the direction D1 in which the one-side connection portion 51 extends (in a side view, the angle formed with the direction perpendicular to the upper edge 25a of the one-side side wall portion 25 is 10° or less).
図４および図８に示すように、握り部材５０の一側接続部５１には、保持凸部４１ｂを収容可能な保持凹部５１ａが設けられている。具体的には、保持凹部５１ａは、上記一側接続部５１の延びる方向Ｄ１に沿って延びている。握り部材５０と一側端部支持部材４１とは、保持凸部４１ｂを保持凹部５１ａに収容することにより接続される。したがって、一側接続部５１を保持凸部４１ｂの突出方向Ｄ１に沿って移動させることにより、握り部材５０と一側端部支持部材４１とを着脱させることができる。保持凸部４１ｂの突出方向Ｄ１と上記一側接続部５１の延びる方向Ｄ１とは同じなので、一側接続部５１を、上記一側接続部５１の延びる方向Ｄ１に沿って移動させることにより（言い換えると、一側接続部５１における握り部材５０の軸線５０ｘに沿って移動させることにより）、握り部材５０と一側端部支持部材４１とを着脱することができる。握り部材５０の着脱方向が上記一側接続部５１の延びる方向Ｄ１に沿っていることにより、幼児座席１０の使用者（幼児座席１０に着座する幼児の保護者、自転車２の運転者）は、握り部材５０の着脱方法を、視覚的に把握することができる。 As shown in FIGS. 4 and 8, the one-side connection portion 51 of the grip member 50 is provided with a holding concave portion 51a capable of accommodating the holding convex portion 41b. Specifically, the holding recessed portion 51a extends along the direction D1 in which the one-side connecting portion 51 extends. The grip member 50 and the one-side end support member 41 are connected by accommodating the holding projection 41b in the holding recess 51a. Therefore, the grip member 50 and the one-side end support member 41 can be attached and detached by moving the one-side connection portion 51 along the projecting direction D1 of the holding protrusion 41b. Since the projecting direction D1 of the holding convex portion 41b is the same as the extending direction D1 of the one-side connecting portion 51, the grip member 50 and the one-side end support member 41 can be attached and detached by moving the one-side connecting portion 51 along the extending direction D1 of the one-side connecting portion 51 (in other words, by moving the one-side connecting portion 51 along the axis 50x of the grip member 50). Since the attachment/detachment direction of the grip member 50 is along the direction D1 in which the one-side connection portion 51 extends, the user of the infant seat 10 (the guardian of the infant seated on the infant seat 10, the rider of the bicycle 2) can visually grasp the attachment/detachment method of the grip member 50.
上述した握り部材５０は、中間部５３を弾性変形させることで、一側接続部５１を一側端部支持部材４１に対して相対移動させることができる。したがって、中間部５３を弾性変形させて、一側接続部５１を保持凸部４１ｂの突出方向Ｄ１に沿って移動させることにより、保持凸部４１ｂは、保持凹部５１ａから抜け出すことができる。なお、図示された例では、中間部５３が弾性変形していない状態で、すなわち握り部材５０に外力が加えられていない状態で、保持凸部４１ｂは保持凹部５１ａ内に位置する。これにより、一側接続部５１と一側端部支持部材４１との着脱を、容易に行うことができる。 The grip member 50 described above can move the one-side connection portion 51 relative to the one-side end support member 41 by elastically deforming the intermediate portion 53 . Therefore, by elastically deforming the intermediate portion 53 and moving the one-side connection portion 51 along the projecting direction D1 of the holding projection 41b, the holding projection 41b can be pulled out of the holding recess 51a. In the illustrated example, the holding projection 41b is positioned within the holding recess 51a when the intermediate portion 53 is not elastically deformed, that is, when the grip member 50 is not subjected to external force. This makes it possible to easily attach and detach the one-side connection portion 51 and the one-side end support member 41 .
図示された例では、一側端部支持部材４１および一側接続部５１は、一側接続部５１を一側端部支持部材４１に接続した状態に維持する維持機構６０を有している。維持機構６０は、保持凸部４１ｂが保持凹部５１ａに収容された状態に維持する。維持機構６０は、保持凸部４１ｂに設けられた突起６１と、一側接続部５１に形成された突起受け６２と、を含む。突起受け６２は、一側接続部５１の内面（保持凹部５１ａを画成する面）に開口する穴である。さらに、一側接続部５１には、維持機構６０による一側接続部５１と一側端部支持部材４１との接続維持状態を解除するための、解除操作部６３が設けられている。 In the illustrated example, the one-side end support member 41 and the one-side connection portion 51 have a maintenance mechanism 60 that maintains the one-side connection portion 51 connected to the one-side end support member 41 . The maintenance mechanism 60 maintains the state in which the holding protrusions 41b are accommodated in the holding recesses 51a. The maintenance mechanism 60 includes a projection 61 provided on the holding convex portion 41 b and a projection receiver 62 formed on the one-side connection portion 51 . The projection receiver 62 is a hole that opens to the inner surface of the one-side connection portion 51 (the surface defining the holding recess 51a). Further, the one-side connection portion 51 is provided with a release operation portion 63 for releasing the connection maintenance state between the one-side connection portion 51 and the one-side end support member 41 by the maintenance mechanism 60 .
図７から理解されるように、突起６１は、保持凸部４１ｂの突出方向Ｄ１と交差する方向Ｄ２に突出している。突起６１は、保持凸部４１ｂ内を上記方向Ｄ２に沿って移動可能であり、上記方向Ｄ２に沿って保持凸部４１ｂの外側に向けて付勢されている。突起６１に保持凸部４１ｂの内側へ向かう力が加わると、突起６１は、保持凸部４１ｂ内に埋没する。図示された例では、突起６１は、保持凸部４１ｂの一側と他側に、それぞれ設けられている。 As understood from FIG. 7, the protrusion 61 protrudes in a direction D2 that intersects with the protrusion direction D1 of the holding protrusion 41b. The projection 61 is movable along the direction D2 within the holding projection 41b, and is biased toward the outside of the holding projection 41b along the direction D2. When a force directed toward the inside of the holding projection 41b is applied to the projection 61, the projection 61 is buried in the holding projection 41b. In the illustrated example, the protrusions 61 are provided on one side and the other side of the holding protrusion 41b.
上述したように、また図８に示すように、突起受け６２は、一側接続部５１の内面に開口している。より詳細には、突起受け６２は、保持凸部４１ｂが保持凹部５１ａに収容された状態で突起６１と対面する位置に、開口している。したがって、保持凸部４１ｂが保持凹部５１ａに収容されると、突起６１は、突起受け６２に嵌まり込む。図示された例では、突起受け６２は、各突起６１に対応して２つ設けられている。また、各突起受け６２は、保持凸部４１ｂが保持凹部５１ａに収容された状態で、突起６１の突出方向Ｄ２と一致する方向に延びている。 As described above and as shown in FIG. 8 , the projection receiver 62 opens on the inner surface of the one-side connection portion 51 . More specifically, the protrusion receiver 62 is open at a position facing the protrusion 61 when the holding protrusion 41b is accommodated in the holding recess 51a. Therefore, when the holding projection 41b is accommodated in the holding recess 51a, the projection 61 is fitted into the projection receiver 62. As shown in FIG. In the illustrated example, two projection receivers 62 are provided corresponding to each projection 61 . Further, each projection receiver 62 extends in a direction coinciding with the projecting direction D2 of the projections 61 in a state in which the holding projections 41b are accommodated in the holding recesses 51a.
突起６１は、保持凸部４１ｂが保持凹部５１ａに収容される際、一側接続部５１の内面によって保持凸部４１ｂの内側へ向けて押されて、保持凸部４１ｂ内に自動的に埋没する。そして、突起６１は、突起受け６２に対面する位置に到達した際、突起６１に加わる付勢力によって、突起受け６２内に自動的に嵌まり込む。すなわち、保持凸部４１ｂを保持凹部５１ａに挿入するだけで、一側接続部５１は、一側端部支持部材４１に対して自動的に固定されるようになる。言い換えると、一側接続部５１と一側端部支持部材４１とは、維持機構６０によって、自動的に接続維持状態とされる。 When the holding convex portion 41b is accommodated in the holding concave portion 51a, the projection 61 is pushed toward the inside of the holding convex portion 41b by the inner surface of the one-side connecting portion 51, and is automatically buried in the holding convex portion 41b. When the protrusion 61 reaches the position facing the protrusion receiver 62 , the protrusion 61 automatically fits into the protrusion receiver 62 due to the biasing force applied to the protrusion 61 . That is, the one-side connecting portion 51 is automatically fixed to the one-side end support member 41 simply by inserting the holding projection 41b into the holding recess 51a. In other words, the one-side connection portion 51 and the one-side end support member 41 are automatically brought into the connection maintenance state by the maintenance mechanism 60 .
次に、解除操作部６３について説明する。解除操作部６３は、突起受け６２内に嵌まり込んだ突起６１を保持凸部４１ｂ内に押し込んで、維持機構６０による接続維持状態を解除するために用いられる。図示された例では、まず、上述した突起受け６２は、一側接続部５１を上記方向Ｄ２に沿って貫通する貫通孔である。そして、解除操作部６３の少なくとも一部は、一側接続部５１の外側から、突起受け６２内に収容されている。解除操作部６３を一側接続部５１の外側から内側へ向けて押し込むことにより、突起６１を保持凸部４１ｂ内に押し込んで、維持機構６０による接続維持状態を解除することができる。図示された例では、解除操作部６３は、２つの突起受け６２の各々に設けられている。 Next, the release operation portion 63 will be described. The release operation part 63 is used to push the projection 61 fitted in the projection receiver 62 into the holding convex part 41 b to release the connection maintained state by the maintenance mechanism 60 . In the illustrated example, first, the projection receiver 62 described above is a through hole penetrating through the one-side connection portion 51 along the direction D2. At least part of the release operation portion 63 is accommodated in the projection receiver 62 from the outside of the one-side connection portion 51 . By pushing the release operation portion 63 inward from the outside of the one-side connection portion 51, the projection 61 can be pushed into the holding convex portion 41b, and the connection maintained state by the maintenance mechanism 60 can be released. In the illustrated example, the release operation portion 63 is provided on each of the two projection receivers 62 .
なお、図示された例では、一側端部支持部材４１は、一側端部支持部材４１を支持する一側側壁部２５よりも幅方向外側で（一側側壁部２５の一側で）、握り部材５０の一側接続部５１と接続している。具体的には、保持凸部４１ｂは、一側側壁部２５よりも幅方向外側に位置している。また、他側端部支持部材４２は、他側端部支持部材４２を支持する他側側壁部２６よりも幅方向外側で（他側側壁部２６の他側で）、握り部材５０の他側端部５２と接続している。具体的には、軸凸部４２ｂは、他側側壁部２６よりも幅方向外側に位置している。これにより、幼児座席１０の居住空間を広く確保することができる。 In the illustrated example, the one-side end support member 41 is connected to the one-side connection portion 51 of the grip member 50 outside the one-side sidewall portion 25 that supports the one-side end support member 41 (on one side of the one-side sidewall portion 25) in the width direction. Specifically, the holding convex portion 41b is positioned outside the one side wall portion 25 in the width direction. In addition, the other side end support member 42 is connected to the other side end 52 of the grip member 50 outside the other side wall portion 26 that supports the other side end support member 42 in the width direction (on the other side of the other side wall portion 26). Specifically, the shaft convex portion 42b is located outside the other side wall portion 26 in the width direction. As a result, a large living space for the infant seat 10 can be ensured.
また、図示された例では、一側端部支持部材４１は、一側端部支持部材４１を支持する一側側壁部２５の上縁２５ａよりも上方で（より詳細には、上記上縁２５ａのうち一側端部支持部材４１が接続する部分よりも上方で）、握り部材５０の一側接続部５１と接続している。具体的には、保持凸部４１ｂは、一側側壁部２５の上縁２５ａよりも上方に位置している。また、他側端部支持部材４２は、他側端部支持部材４２を支持する他側側壁部２６の上縁２６ａよりも上方で（より詳細には、上記上縁２６ａのうち他側端部支持部材４２が接続する部分よりも上方で）、握り部材５０の他側端部５２と接続している。具体的には、軸凸部４２ｂは、他側側壁部２６の上縁２６ａよりも上方に位置している。このことによっても、幼児座席１０の居住空間を広く確保することができる。 In the illustrated example, the one-side end support member 41 is connected to the one-side connection portion 51 of the grip member 50 above the upper edge 25a of the one-side sidewall portion 25 that supports the one-side end support member 41 (more specifically, above the portion of the upper edge 25a where the one-side end support member 41 is connected). Specifically, the holding convex portion 41b is positioned above the upper edge 25a of the side wall portion 25 on one side. The other end support member 42 is connected to the other end 52 of the grip member 50 above the upper edge 26a of the other side wall portion 26 that supports the other end support member 42 (more specifically, above the portion of the upper edge 26a to which the other end support member 42 is connected). Specifically, the shaft protrusion 42 b is located above the upper edge 26 a of the other side wall portion 26 . Due to this also, a large living space for the infant seat 10 can be ensured.
ここで、本実施の形態の幼児座席１０による、握り部材５０の操作方法について説明する。 Here, a method of operating the grip member 50 using the infant seat 10 of this embodiment will be described.
まず、握り部材５０を、図３に示す位置から図６に示す位置に移動させる際の操作方法について説明する。握り部材５０が図３に示す状態にある場合、握り部材５０の一側接続部５１は、一側端部支持部材４１に接続されている。より具体的には、一側端部支持部材４１の保持凸部４１ｂが、一側端部５１の保持凹部５１ａに収容されている。また、保持凸部４１ｂの突起６１が、一側端部５１の突起受け６２に嵌まり込んでいる。握り部材５０を図３に示す位置から図６に示す位置に移動させる場合、まず、解除操作部６３を一側端部５１の内側に押し込んで、突起６１を保持凸部４１ｂ内に埋没させる。この状態を維持したまま、一側端部５１を一側端部５１の延びる方向Ｄ１に沿って持ち上げる。このとき、握り部材５０の中間部５３を弾性変形させながら一側端部５１を持ち上げる。一側端部５１が十分に持ち上がって一側端部支持部材４１の保持凸部４１ｂが一側端部５１の保持凹部５１ａから抜け出したら、握り部材５０を、他側端部支持部材４２の軸凸部４２ｂの周りで（したがって、他側接続部５２の延びる方向Ｄ１に沿った回転軸線を中心として）回転させて、図６に示す位置まで移動させる。 First, an operation method for moving the grip member 50 from the position shown in FIG. 3 to the position shown in FIG. 6 will be described. When the grip member 50 is in the state shown in FIG. 3, the one side connection portion 51 of the grip member 50 is connected to the one side end support member 41 . More specifically, the holding projection 41 b of the one-side end support member 41 is accommodated in the holding recess 51 a of the one-side end 51 . Also, the projection 61 of the holding projection 41 b is fitted into the projection receiver 62 of the one side end 51 . When moving the grip member 50 from the position shown in FIG. 3 to the position shown in FIG. 6, first, the release operation portion 63 is pushed inside the one side end portion 51 so that the projection 61 is buried in the holding projection portion 41b. While maintaining this state, the one-side end 51 is lifted along the direction D1 in which the one-side end 51 extends. At this time, the one side end portion 51 is lifted while elastically deforming the intermediate portion 53 of the grip member 50 . When the one-side end 51 is sufficiently raised and the holding projection 41b of the one-side end support member 41 is pulled out of the holding recess 51a of the one-side end 51, the grip member 50 is rotated around the shaft projection 42b of the other-side end support member 42 (thus, about the rotation axis along the direction D1 in which the other-side connection portion 52 extends) to the position shown in FIG.
次に、握り部材５０を、図６に示す位置から図３に示す位置に移動させる際の操作方法について説明する。まず、握り部材５０を、他側端部支持部材４２の軸凸部４２ｂの周りで（したがって、他側接続部５２の延びる方向Ｄ１に沿った回転軸線を中心として）回転させる。握り部材５０の一側接続部５１が一側端部支持部材４１の近傍に到達したら、中間部５３を弾性変形させて、一側接続部５１を、側壁部２６の上縁２６ａよりも上方に持ち上げる。握り部材５０を軸凸部４２ｂの周りでさらに回転させ、一側接続部５１の保持凹部５１ａと一側端部支持部材４１の保持凸部４１ｂとが対面したら、中間部５３の弾性変形を低減させながら、一側接続部５１を保持凸部４１ｂの突出方向Ｄ１に沿って移動させる。そして、保持凸部４１ｂを保持凹部５１ａに収容する。このとき、保持凸部４１ｂの突起６１は、上述したように、保持凸部４１ｂ内に自動的に埋没し、その後、保持凹部５１ａの突起受け６２に嵌まり込む。これにより、一側接続部５１と一側端部支持部材４１との接続が維持される。 Next, an operation method for moving the grip member 50 from the position shown in FIG. 6 to the position shown in FIG. 3 will be described. First, the grip member 50 is rotated around the shaft protrusion 42b of the other-side end support member 42 (thus, about the rotation axis along the direction D1 in which the other-side connection portion 52 extends). When the one-side connection portion 51 of the grip member 50 reaches the vicinity of the one-side end support member 41 , the intermediate portion 53 is elastically deformed to lift the one-side connection portion 51 above the upper edge 26 a of the side wall portion 26 . The grip member 50 is further rotated around the shaft projection 42b, and when the holding recess 51a of the one-side connection portion 51 and the holding projection 41b of the one-side end support member 41 face each other, the one-side connection portion 51 is moved along the projecting direction D1 of the holding projection 41b while reducing the elastic deformation of the intermediate portion 53. Then, the holding convex portion 41b is accommodated in the holding concave portion 51a. At this time, as described above, the projection 61 of the holding projection 41b is automatically buried in the holding projection 41b and then fitted into the projection receiver 62 of the holding recess 51a. Thereby, the connection between the one-side connecting portion 51 and the one-side end support member 41 is maintained.
次に、図９～図１１を参照して座席本体２０に装着されるフットカバー７０について説明する。図９には、フットカバー７０が装着された幼児座席１０が示されており、図１０には、フットカバー７０全体構成が示されている。また、図１１には、フットカバー７０を座席本体２０から取り外す方法が示されている。 Next, the foot cover 70 attached to the seat body 20 will be described with reference to FIGS. 9 to 11. FIG. 9 shows the infant seat 10 to which the foot cover 70 is attached, and FIG. 10 shows the overall construction of the foot cover 70. As shown in FIG. 11 shows a method of removing the foot cover 70 from the seat body 20. As shown in FIG.
図９に示すように、フットカバー７０は、幼児座席１０の座面部２１と周壁部２８の前側半部とを覆って、フット幼児座席１０に着座した幼児に風よけの空間を提供する。 As shown in FIG. 9, the foot cover 70 covers the seat surface portion 21 of the infant seat 10 and the front half portion of the peripheral wall portion 28 to provide the infant seated on the foot infant seat 10 with a windbreak space.
図９および図１０に示すように、フットカバー７０は、座席本体２０に装着された状態で、座面部２１を上方から覆う前面部７１と、周壁部２８の前側半部を外側から覆う周面部７２と、接続部２７および座面部２１の一部を下方から覆う下面部７３と、を有する。前面部７１と下面部７３とは、対向して配置され、周面部７２によって接続されている。これにより、前面部７１と周面部７２と下面部７３とは、袋状をなしている。さらに、フットカバー７０は、握り部材５０に巻き付けられる巻き付け部７４を有する。巻き付け部７４は、前面部７１の上端縁に接続している。巻き付け部７４および前面部７１には、留め具７５が設けられており、巻き付け部７４と前面部７１とを対面した状態に維持することができるようになっている。留め具７５としては、面ファスナーやスナップボタン等、種々の留め具を用いることができる。図９に示すように、巻き付け部７４を握り部材５０の中間部５３に巻き付けて、巻き付け部７４と前面部７１とを留め具７５で留めることにより、フットカバー７０を握り部材５０に取り付けることができる。このようにして握り部材５０に取り付けられ、座席本体２０に装着されたフットカバー７０は、図１１に示すように、握り部材５０の一側接続部５１を一側端部支持部材４１から外して、握り部材５０を他側端部支持部材４２の軸凸部４２ｂの周りで回転させるだけで、座席本体２０から取り外すことができる。すなわち、幼児を幼児座席１０から下ろすために握り部材５０を移動させると同時に、フットカバー７０を座席本体２０から取り外すことができる。 9 and 10, the foot cover 70 has a front surface portion 71 that covers the seat surface portion 21 from above, a peripheral surface portion 72 that covers the front half of the peripheral wall portion 28 from the outside, and a lower surface portion 73 that covers the connection portion 27 and a part of the seat surface portion 21 from below. The front surface portion 71 and the lower surface portion 73 are arranged to face each other and are connected by a peripheral surface portion 72 . Thus, the front surface portion 71, the peripheral surface portion 72, and the lower surface portion 73 form a bag shape. Furthermore, the foot cover 70 has a winding portion 74 that is wound around the grip member 50 . The winding portion 74 is connected to the upper edge of the front portion 71 . A fastener 75 is provided on the winding portion 74 and the front surface portion 71 so that the winding portion 74 and the front surface portion 71 can be maintained facing each other. Various fasteners such as hook-and-loop fasteners and snap buttons can be used as the fasteners 75 . As shown in FIG. 9, the foot cover 70 can be attached to the grip member 50 by winding the winding portion 74 around the intermediate portion 53 of the grip member 50 and fastening the winding portion 74 and the front portion 71 with fasteners 75. As shown in FIG. 11, the foot cover 70 attached to the grip member 50 and attached to the seat body 20 can be removed from the seat body 20 simply by removing the one-side connecting portion 51 of the grip member 50 from the one-side end support member 41 and rotating the grip member 50 around the shaft protrusion 42b of the other-side end support member 42. That is, the foot cover 70 can be removed from the seat body 20 at the same time that the grip member 50 is moved to get the infant out of the infant seat 10 .
図１０に示す例では、フットカバー７０は、さらに、フットカバー７０をハンドル６に取り付けるための取り付け部材７６を有している。図示された例では、取り付け部材７６は、一端が下面部７３の縁部に固定された紐状の部材である。取り付け部材７６の両端部には、当該両端部を接続する留め具７７が設けられている。留め具７７としては、面ファスナーやスナップボタン等、種々の留め具を用いることができる。取り付け部材７６をハンドル６に巻き付けて両端部を留め具７７で接続することにより、フットカバー７０の下面部７３を、取り付け部材７６を介してハンドル６に接続することができる。これにより、意図せずフットカバー７０が座席本体２０から外れてしまう虞が、低減される。 In the example shown in FIG. 10, the foot cover 70 further has an attachment member 76 for attaching the foot cover 70 to the handle 6. As shown in FIG. In the illustrated example, the attachment member 76 is a string-like member having one end fixed to the edge of the lower surface portion 73 . Both ends of the mounting member 76 are provided with fasteners 77 that connect the two ends. Various fasteners such as hook-and-loop fasteners and snap buttons can be used as the fasteners 77 . By winding the mounting member 76 around the handle 6 and connecting both ends with fasteners 77 , the lower surface portion 73 of the foot cover 70 can be connected to the handle 6 via the mounting member 76 . This reduces the risk that the foot cover 70 will unintentionally come off the seat body 20 .
なお、上述した自転車２、幼児座席１０およびフットカバー７０は、一例に過ぎず、種々の変更が可能である。 The bicycle 2, infant seat 10, and foot cover 70 described above are merely examples, and various modifications are possible.
例えば、上述した実施例では、一側端部支持部材４１に保持凸部４１ｂが設けられ、握り部材５０の一側接続部５１に保持凹部５１ａが設けられる例について説明してきた。しかしながら、一側接続部５１に保持凸部が設けられ、一側端部支持部材４１に保持凹部が設けられてもよい。この場合も、保持凸部は、一側接続部５１と一側端部支持部材４１とを着脱する際の一側接続部５１および一側端部支持部材４１の相対移動方向Ｄ１に突出し、保持凹部５１ａは、当該相対移動方向Ｄ１に延びていればよい。 For example, in the above-described embodiments, the one-side end support member 41 is provided with the holding projection 41b, and the one-side connection portion 51 of the grip member 50 is provided with the holding recess 51a. However, the one-side connecting portion 51 may be provided with a holding projection and the one-side end support member 41 may be provided with a holding recess. In this case as well, the holding projection projects in the relative movement direction D1 of the one-side connection portion 51 and the one-side end support member 41 when the one-side connection portion 51 and the one-side end support member 41 are attached and detached, and the holding recess 51a only needs to extend in the relative movement direction D1.
また、この場合、一側端部支持部材４１に設けられた保持凹部を、一側端部支持部材４１を支持する一側側壁部２５よりも幅方向外側に配置することにより、幼児座席１０の居住空間を広く確保することができる。また、一側端部支持部材４１に設けられた保持凹部を、一側端部支持部材４１を支持する一側側壁部２５の上縁２５ａよりも上方に配置することにより、居住空間を広く確保することができる。 Further, in this case, by arranging the holding recess provided in the one-side end support member 41 outside the one-side side wall portion 25 that supports the one-side end support member 41 in the width direction, it is possible to secure a wide living space for the infant seat 10. Further, by arranging the holding recess provided in the one-side end support member 41 above the upper edge 25a of the one-side side wall portion 25 that supports the one-side end support member 41, a wide living space can be secured.
また、上述した実施例では、一側接続部５１を一側端部支持部材４１に対して保持凸部４１ｂの突出方向Ｄ１に移動させて、一側接続部５１および一側端部支持部材４１の着脱を行う例について説明してきた。しかしながら、一側接続部５１および一側端部支持部材４１の着脱を行う際の一側接続部５１および一側端部支持部材４１の相対移動方向は、保持凸部４１ｂの突出方向Ｄ１に沿っていなくてもよい。例えば、図１２に示すように、上記相対移動方向は、握り部材５０を軸凸部４２ｂの周りで回転させる際の一側接続部５１の移動方向Ｄ３に沿った方向であってもよい。この場合、保持凹部５１ａは、図１２および図１３に示すように、上記移動方向Ｄ３に沿って一側接続部５１の外周面から内部へ延びていればよい。また、この場合、握り部材５０は、弾性変形可能でなくてもよい。 In the above-described embodiment, the one-side connecting portion 51 and the one-side end supporting member 41 are attached and detached by moving the one-side connecting portion 51 with respect to the one-side end supporting member 41 in the projecting direction D1 of the holding convex portion 41b. However, the relative movement direction of the one-side connection portion 51 and the one-side end support member 41 when attaching and detaching the one-side connection portion 51 and the one-side end support member 41 does not have to be along the projecting direction D1 of the holding convex portion 41b. For example, as shown in FIG. 12, the direction of relative movement may be a direction along the movement direction D3 of the one-side connection portion 51 when the grip member 50 is rotated around the shaft projection 42b. In this case, as shown in FIGS. 12 and 13, the holding recess 51a may extend inward from the outer peripheral surface of the one-side connecting portion 51 along the moving direction D3. Also, in this case, the grip member 50 may not be elastically deformable.
さらに、上述した実施例では、幼児座席１０がハンドル６に固定される例について説明してきたが、これに限られない。例えば、座席本体２０は自転車２の荷台８に取り付け可能な形状を有し、幼児座席１０は荷台８に取り付けられてもよい。 Furthermore, in the above-described embodiment, an example in which the infant seat 10 is fixed to the handle 6 has been described, but the present invention is not limited to this. For example, the seat body 20 may have a shape that can be attached to the carrier 8 of the bicycle 2 and the infant seat 10 may be attached to the carrier 8 .
以上のように、本実施の形態によれば、自転車用幼児座席１０は、自転車２に取り付けられる幼児用の座席である。幼児座席１０は、座面部２１と座面部２１の両側方から接続した一対の側壁部２５，２６とを有する座席本体２０と、座席本体２０の一対の側壁部２５，２６にそれぞれ設けられた端部支持部材４１，４２に、両端部５１，５２において接続した握り部材５０と、を備えている。握り部材５０は、その一側端部５１において、一側端部支持部材４１に着脱可能となっている。また、握り部材５０は、その他側端部５２において、握り部材５０の軸線５０ｘに沿った回転軸線を中心として回転可能に他側端部支持部材４２に接続している。 As described above, according to this embodiment, the bicycle infant seat 10 is a seat for an infant attached to the bicycle 2 . The infant seat 10 includes a seat body 20 having a seat surface part 21 and a pair of side wall parts 25, 26 connected from both sides of the seat surface part 21, and a grip member 50 connected at both ends 51, 52 to end support members 41, 42 respectively provided on the pair of side wall parts 25, 26 of the seat body 20. The grip member 50 can be attached to and detached from the one-side end support member 41 at its one-side end portion 51 . Further, the grip member 50 is connected at the other side end 52 to the other side end support member 42 so as to be rotatable about a rotation axis along the axis 50x of the grip member 50 .
このような幼児座席１０によれば、幼児を幼児座席１０に乗せ降ろしし易いよう、握り部材５０を座面部２１の上方から移動させることができる。具体的には、握り部材５０の一側端部５１を一側端部支持部材４１から取り外し、他側端部５２を他側端部支持部材４２に対して回転させることにより、握り部材５０を、座面部２１の上方から座面部２１の側方へ移動させることができる。また、握り部材５０を移動させる際、握り部材５０がその軸線５０ｘに沿った回転軸線を中心として回転するので、握り部材５０の端部支持部材４１から取り外された一側端部５１は、座面部２１の周囲を通過する。握り部材５０の端部５１が座面部２１の上方を通過しないので、当該端部５１が幼児座席１０に着座する幼児に接触して幼児がけがをする虞が低減される。さらに、握り部材５０を座席本体２０の縁２８ａに沿って移動させることができるので、握り部材５０が幼児座席１０の周囲に位置するものと干渉する虞も低減される。 According to the infant seat 10 as described above, the grip member 50 can be moved from above the seat surface portion 21 so that the infant can be easily put on and off the infant seat 10 . Specifically, by removing one side end 51 of the grip member 50 from the one side end support member 41 and rotating the other side end 52 with respect to the other side end support member 42, the grip member 50 can be moved from above the seat surface portion 21 to the side of the seat surface portion 21. Further, when the grip member 50 is moved, the grip member 50 rotates around the rotation axis along the axis 50x, so that the one side end 51 of the grip member 50 removed from the end support member 41 passes around the seat surface 21. Since the end portion 51 of the grip member 50 does not pass above the seat surface portion 21, the risk of the end portion 51 contacting the child seated on the child seat 10 and injuring the child is reduced. Furthermore, since the grip member 50 can be moved along the edge 28a of the seat body 20, the possibility of the grip member 50 interfering with the surroundings of the infant seat 10 is also reduced.
また、本実施の形態において、一側端部５１における握り部材５０の軸線５０ｘに沿った方向に、一側端部５１を一側端部支持部材４１に対して相対移動させることで、握り部材５０は一側端部支持部材４１に着脱可能となっている。このような幼児座席１０によれば、一側端部５１の延びる方向に沿って一側端部５１を移動させることで、握り部材５０を一側端部支持部材４１に着脱させることができるので、握り部材５０の操作方法を視覚的に把握することができる。したがって、使用者は、幼児座席１０を容易に取り扱うことができる。 In the present embodiment, the grip member 50 can be attached to and detached from the one-side end support member 41 by moving the one-side end portion 51 relative to the one-side end support member 41 in the direction along the axis 50x of the grip member 50 at the one-side end portion 51. According to the infant seat 10, the grip member 50 can be attached to and detached from the one-side end support member 41 by moving the one-side end portion 51 along the direction in which the one-side end portion 51 extends. Therefore, a user can easily handle the infant seat 10 .
また、本実施の形態において、一側端部５１および一側端部支持部材４１の一方が、相対移動方向Ｄ１に突出した保持凸部４１ｂを有し、一側端部５１および一側端部支持部材４１の他方が、保持凸部４１ｂを収容可能な保持凹部５１ａを有している。このような一側端部５１と一側端部支持部材４１とは、着脱が容易である。 Further, in the present embodiment, one of the one-side end portion 51 and the one-side end support member 41 has a holding protrusion 41b projecting in the relative movement direction D1, and the other of the one-side end portion 51 and the one-side end support member 41 has a holding recess 51a capable of accommodating the holding protrusion 41b. Such one-side end portion 51 and one-side end support member 41 can be easily attached and detached.
また、本実施の形態において、握り部材５０は、少なくとも一部分において弾性変形可能であり、握り部材５０が弾性変形することで保持凸部４１ｂが保持凹部５１ａから抜け出し可能となっている。このような握り部材５０によれば、複雑な機構を伴うことなく、一側端部５１と一側端部支持部材４１とを着脱させることができる。 In the present embodiment, at least a portion of the grip member 50 is elastically deformable, and the elastic deformation of the grip member 50 allows the holding convex portion 41b to slip out of the holding concave portion 51a. According to such a grip member 50, the one-side end portion 51 and the one-side end support member 41 can be attached and detached without a complicated mechanism.
また、本実施の形態において、握り部材５０は、少なくとも一部分において弾性変形可能であり、外力が加えられていない状態で、保持凸部４１ｂが保持凹部５１ａ内に位置する。これにより、保持凸部４１ｂと保持凹部５１ａとを、容易に接続することができる。 Moreover, in the present embodiment, the grip member 50 is elastically deformable in at least a portion thereof, and the holding projection 41b is positioned within the holding recess 51a in a state in which no external force is applied. Thereby, the holding convex portion 41b and the holding concave portion 51a can be easily connected.
また、本実施の形態において、一側端部支持部材４１に設けられた保持凸部４１ｂ又は保持凹部５１ａは、一側端部支持部材４１を支持する一側側壁部２５よりも幅方向外側に位置している。これにより、幼児座席１０の居住空間を広く確保することができる。 Further, in the present embodiment, the holding convex portion 41b or the holding concave portion 51a provided in the one-side end support member 41 is positioned outside the one-side sidewall portion 25 that supports the one-side end support member 41 in the width direction. As a result, a large living space for the infant seat 10 can be ensured.
また、本実施の形態において、一側端部支持部材４１に設けられた保持凸部４１ｂ又は保持凹部５１ａは、一側端部支持部材４１を支持する一側側壁部２５の上縁２５ａよりも上方に位置している。これにより、幼児座席１０の居住空間を広く確保することができる。 Further, in the present embodiment, the holding projection 41b or the holding recess 51a provided on the one-side end support member 41 is positioned above the upper edge 25a of the one-side sidewall 25 that supports the one-side end support member 41. As a result, a large living space for the infant seat 10 can be ensured.
また、本実施の形態において、一側端部支持部材４１は、一側端部支持部材４１を支持する一側側壁部２５よりも幅方向外側において握り部材５０の一側端部５１と接続し、他側端部支持部材４２は、他側端部支持部材４２を支持する他側側壁部２６よりも幅方向外側において握り部材５０の他側端部５２と接続している。これにより、幼児座席１０の居住空間を広く確保することができる。 In the present embodiment, the one-side end support member 41 is connected to the one-side end 51 of the grip member 50 outside the one-side sidewall 25 that supports the one-side end support member 41 in the width direction, and the other-side end support member 42 is connected to the other-side end 52 of the grip member 50 outside the other-side sidewall 26 that supports the other-side end support member 42 in the width direction. As a result, a large living space for the infant seat 10 can be ensured.
また、本実施の形態において、一側端部支持部材４１は、一側端部支持部材４１を支持する一側側壁部２５の上縁２５ａよりも上方において握り部材５０の一側端部５１と接続し、他側端部支持部材４２は、他側端部支持部材４２を支持する他側側壁部２６の上縁２６ａよりも上方において握り部材５０の他側端部５２と接続している。これにより、幼児座席１０の居住空間を広く確保することができる。 In the present embodiment, the one-side end support member 41 is connected to the one-side end 51 of the grip member 50 above the upper edge 25a of the one-side sidewall 25 that supports the one-side end support member 41, and the other-side end support member 42 is connected to the other-side end 52 of the grip member 50 above the upper edge 26a of the other-side sidewall 26 that supports the other-side end support member 42. As a result, a large living space for the infant seat 10 can be ensured.
また、本実施の形態において、側面視において、側壁部２５，２６の縁２５，２６に垂直な方向に対してなす角度が１０°以下となる方向に、握り部材５０の両端部５１，５２は端部支持部材４１，４２から延び出している。これにより、握り部材５０の回転軸線が延びる方向が、側壁部２５，２６の縁２５，２６に垂直な方向に対してなす角度が１０°以下となる方向となる。このような回転軸線を中心として握り部材５０が回転することにより、握り部材５０を移動させる際に握り部材５０の一側端部５１が座面部２１の上方を通過することを、より効果的に防止することができる。また、握り部材５０が、より座席本体２０の縁２８ａに沿って移動するようになる。これにより、握り部材５０が幼児座席１０の周囲に位置するものと干渉する虞を、効果的に低減させることができる。 In the present embodiment, both ends 51 and 52 of the grip member 50 extend from the end support members 41 and 42 in a direction that forms an angle of 10° or less with respect to the direction perpendicular to the edges 25 and 26 of the side walls 25 and 26 when viewed from the side. As a result, the direction in which the rotation axis of the grip member 50 extends forms an angle of 10° or less with respect to the direction perpendicular to the edges 25 and 26 of the side wall portions 25 and 26 . By rotating the grip member 50 around such a rotation axis, it is possible to more effectively prevent the one side end portion 51 of the grip member 50 from passing over the seat surface portion 21 when the grip member 50 is moved. Also, the grip member 50 moves more along the edge 28 a of the seat body 20 . As a result, the possibility that the grip member 50 interferes with objects positioned around the infant seat 10 can be effectively reduced.
また、本実施の形態において、幼児座席１０は、座席本体２０に着脱可能なフットカバー７０を更に備え、フットカバー７０は、握り部材５０に取り付け可能となっている。これにより、握り部材５０の回転にともなってフットカバー７０を座席本体２０から外すことができる。すなわち、幼児を幼児座席１０から下ろすために握り部材５０を移動させると同時に、フットカバー７０を座席本体２０から取り外すことができる。 In this embodiment, the infant seat 10 further includes a foot cover 70 that can be attached to and detached from the seat body 20 , and the foot cover 70 can be attached to the grip member 50 . As a result, the foot cover 70 can be removed from the seat body 20 as the grip member 50 rotates. That is, the foot cover 70 can be removed from the seat body 20 at the same time that the grip member 50 is moved to get the infant out of the infant seat 10 .
また、本実施の形態による幼児座席付き自転車１は、上述した幼児座席１０と、幼児座席１０を取り付けられた自転車２と、を備える。このような幼児座席付き自転車１によれば、幼児を幼児座席１０に乗せ降ろしし易いよう、握り部材５０を座面部２１の上方から移動させることができる。具体的には、握り部材５０の一側端部５１を一側端部支持部材４１から取り外し、他側端部５２を他側端部支持部材４２に対して回転させることにより、握り部材５０を座面部２１の上方から座面部２１の側方へ移動させることができる。また、握り部材５０を移動させる際、握り部材５０がその軸線５０ｘに沿った回転軸線を中心として回転するので、握り部材５０の端部支持部材４１から取り外された一側端部５１は、座面部２１の周囲を通過する。握り部材５０の端部５１が座面部２１の上方を通過しないので、当該端部５１が幼児座席１０に着座する幼児に接触して幼児がけがをする虞が低減される。さらに、握り部材５０を座席本体２０の縁２８ａに沿って移動させることができるので、握り部材５０が幼児座席１０の周囲に位置するものと干渉する虞も低減される。 Further, the bicycle 1 with an infant seat according to this embodiment includes the infant seat 10 described above and the bicycle 2 to which the infant seat 10 is attached. According to such a bicycle 1 with an infant seat, the grip member 50 can be moved from above the seat surface portion 21 so that the infant can be easily put on and off the infant seat 10 . Specifically, by removing one side end 51 of the grip member 50 from the one side end support member 41 and rotating the other side end 52 with respect to the other side end support member 42, the grip member 50 can be moved from above the seat surface portion 21 to the side of the seat surface portion 21. Further, when the grip member 50 is moved, the grip member 50 rotates around the rotation axis along the axis 50x, so that the one side end 51 of the grip member 50 removed from the end support member 41 passes around the seat surface 21. Since the end portion 51 of the grip member 50 does not pass above the seat surface portion 21, the risk of the end portion 51 contacting the child seated on the child seat 10 and injuring the child is reduced. Furthermore, since the grip member 50 can be moved along the edge 28a of the seat body 20, the possibility of the grip member 50 interfering with the surroundings of the infant seat 10 is also reduced.
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。 Although several modifications of the above-described embodiment have been described above, it is of course possible to apply a plurality of modifications in appropriate combination.
