  • the above-mentioned seat has a pair of side wall portions arranged on the left and right sides of the seat surface portion. Further, each side wall portion is urged by an elastic member so as to be bent inward in the left-right direction. This prevents the side walls from being folded so as to expand outward in the left and right direction as the stroller is folded (and thus from being stored with the side walls of the seat sandwiched between the stroller body (frame)). The effect of being carried out is demonstrated.
  • the above effect may be weakened (or no longer obtained) as the elastic member deteriorates over time. Furthermore, even when the stroller is in its unfolded state (that is, when an infant can ride in the stroller), the force exerted by the elastic member acts on the side wall, causing the side wall to bend slightly inward in the left-right direction. The width of the infant riding space in the left-right direction may be compressed by the above-mentioned bend. In addition, the space between the outside of the side wall in the left-right direction and the main body (frame) of the baby carriage becomes larger due to the above bending, which causes the problem that parts of the infant's body or toys are likely to get caught in the space. obtain.

Description

乳母車用シート及び乳母車Baby carriage seats and baby carriages
　本開示の一側面は、乳母車用シート及び乳母車に関する。 One aspect of the present disclosure relates to a baby carriage seat and a baby carriage.
　従来、乳母車本体と、乳母車本体に支持されるシートと、を有する乳母車が知られている（例えば、特許文献１）。特許文献１に記載されている乳母車用のシートは、シートの座面部と背当部とが接近するように折り畳むことが可能に構成されている。上記シートは、座面部の左右に配置された一対の側壁部を有している。また、各側壁部は、弾性部材によって左右方向における内側に折れ曲がるように付勢されている。これにより、乳母車の折り畳み動作に伴って側壁部が左右方向の外側に拡がるように折り畳まれること（ひいては、シートの側壁部が乳母車本体（フレーム）に挟まれた状態で保管されること）が防止されるという効果が発揮される。 Conventionally, a baby carriage is known that includes a baby carriage body and a seat supported by the baby carriage body (for example, Patent Document 1). The baby carriage seat described in Patent Document 1 is configured to be foldable so that the seat portion and backrest portion of the seat are close to each other. The above-mentioned seat has a pair of side wall portions arranged on the left and right sides of the seat surface portion. Further, each side wall portion is urged by an elastic member so as to be bent inward in the left-right direction. This prevents the side walls from being folded so as to expand outward in the left and right direction as the stroller is folded (and thus from being stored with the side walls of the seat sandwiched between the stroller body (frame)). The effect of being carried out is demonstrated.
特開２０１６－１９３６５３号公報Japanese Patent Application Publication No. 2016-193653
　上記特許文献１に記載された構成では、経時的な弾性部材の劣化に伴って上記効果が弱まる（或いは得られなくなる）おそれがある。また、乳母車の展開状態（すなわち、乳母車に乳幼児が乗車可能な状態）においても、側壁部に対して、弾性部材によって付勢される力が働くため、側壁部が左右方向の内側に若干折れ曲がり、上記折れ曲がりの分だけ乳幼児の乗車スペースの左右方向の幅が圧迫されるおそれがある。また、上記折れ曲がりの分だけ側壁部の左右方向の外側と乳母車本体（フレーム）との間のスペースが大きくなり、当該スペースに乳幼児の身体の一部や玩具等が挟まれ易くなるという問題も生じ得る。 In the configuration described in Patent Document 1, the above effect may be weakened (or no longer obtained) as the elastic member deteriorates over time. Furthermore, even when the stroller is in its unfolded state (that is, when an infant can ride in the stroller), the force exerted by the elastic member acts on the side wall, causing the side wall to bend slightly inward in the left-right direction. The width of the infant riding space in the left-right direction may be compressed by the above-mentioned bend. In addition, the space between the outside of the side wall in the left-right direction and the main body (frame) of the baby carriage becomes larger due to the above bending, which causes the problem that parts of the infant's body or toys are likely to get caught in the space. obtain.
　本開示の一側面は、乳母車の展開状態における乳幼児の乗車スペースが圧迫されることを防止しつつ、乳母車の折り畳み動作時に側壁部が左右方向の外側に拡がるように折り畳まれることを防止することができる乳母車用シート、及び上記乳母車用シートを備えた乳母車を提供することを目的とする。 One aspect of the present disclosure is to prevent the seating space for an infant from being compressed when the stroller is in the unfolded state, and to prevent the side walls from being folded so as to expand outward in the left-right direction during the folding operation of the stroller. An object of the present invention is to provide a baby carriage seat that can be used as a baby carriage, and a baby carriage equipped with the baby carriage seat.
　本開示の一側面に係る乳母車用シートは、展開状態から折り畳み状態へと折り畳み可能な乳母車に装着される乳母車用シートであって、座面部と、座面部に接続された背当部と、展開状態における左右方向の座面部の両側に配置された一対の側壁部と、を備える。側壁部は、第１補強板と、第１補強板に対して座面部が位置する側とは反対側に配置される第２補強板と、第１補強板と第２補強板とを接続する接続部材と、を有する。第１補強板は、左右方向において座面部が位置する側を向く第１内面と、第１内面とは反対側の第１外面と、第１内面と第１外面とを接続し、展開状態において第２補強板と接触する第１端面と、を有する。第２補強板は、左右方向において座面部が位置する側を向く第２内面と、第２内面とは反対側の第２外面と、第２内面と第２外面とを接続し、展開状態において第１端面と接触する第２端面と、を有する。接続部材は、少なくとも第１補強板と第２補強板との境界に沿って折り曲げ可能とされている。接続部材は、第１外面と第２外面とがなす角度が減少する方向に第１補強板が第２補強板に対して折れ曲がるように第１補強板及び第２補強板を付勢しない態様で、第１外面と第２外面とに固定されている。 A baby carriage seat according to one aspect of the present disclosure is a baby carriage seat attached to a baby carriage that can be folded from an unfolded state to a folded state, and includes a seat part, a backrest part connected to the seat part, and an unfolded seat part. A pair of side wall parts arranged on both sides of the seat part in the left-right direction in the state. The side wall portion connects the first reinforcing plate, the second reinforcing plate located on the opposite side of the first reinforcing plate from the side where the seat portion is located, and the first reinforcing plate and the second reinforcing plate. A connecting member. The first reinforcing plate connects the first inner surface facing the side where the seat portion is located in the left-right direction, the first outer surface opposite to the first inner surface, the first inner surface and the first outer surface, and in the deployed state. It has a first end surface that contacts the second reinforcing plate. The second reinforcing plate connects a second inner surface facing the side where the seat portion is located in the left-right direction, a second outer surface opposite to the second inner surface, and the second inner surface and the second outer surface, and in the unfolded state. It has a second end surface that contacts the first end surface. The connecting member is bendable at least along the boundary between the first reinforcing plate and the second reinforcing plate. The connecting member is configured such that the first reinforcing plate and the second reinforcing plate are not biased so that the first reinforcing plate is bent relative to the second reinforcing plate in a direction in which the angle formed by the first outer surface and the second outer surface decreases. , fixed to the first outer surface and the second outer surface.
　上記乳母車用シートでは、各側壁部は、接続部材を介して互いに接続された第１補強板及び第２補強板を有する。接続部材は、少なくとも第１補強板及び第２補強板の境界に沿って折り曲げ可能とされている。これにより、第１外面と第２外面とが互いに近づく方向に、第１補強板を第２補強板に対して折り曲げること（すなわち、側壁部を左右方向の内側に突出するように折り曲げること）ができる。一方、接続部材が各補強板の外面（すなわち、第１外面及び第２外面）に固定されているため、第１補強板の第１端面のうち第１外面に接続される縁部と第２補強板の第２端面のうち第２外面に接続される縁部とが接触（或いは近接）した状態が維持される。すなわち、第１内面と第２内面とが互いに近づく方向に第１補強板が第２補強板に対して折れ曲がること（すなわち、側壁部が左右方向の外側に突出するように折れ曲がること）が防止される。従って、乳母車の折り畳み動作時において、側壁部が左右方向の外側に拡がるように折り畳まれることが防止される。さらに、接続部材は、第１外面と第２外面とがなす角度が減少する方向に第１補強板が第２補強板に対して折れ曲がるように第１補強板及び第２補強板を付勢しない態様で、第１補強板と第２補強板とを接続している。すなわち、展開状態において、接続部材は、側壁部が左右方向の内側に突出するように折れ曲がることを助長しないように構成されている。これにより、展開状態において、第１補強板と第２補強板とが平行な状態（すなわち、第１端面と第２端面とが接触し、第１外面及び第２外面が面一な状態）が適切に維持され、乳幼児の乗車スペースが側壁部によって圧迫されることが防止される。 In the above baby carriage seat, each side wall portion has a first reinforcing plate and a second reinforcing plate that are connected to each other via a connecting member. The connecting member is bendable at least along the boundary between the first reinforcing plate and the second reinforcing plate. This makes it possible to bend the first reinforcing plate relative to the second reinforcing plate in a direction in which the first outer surface and the second outer surface approach each other (that is, bending the side wall portion so as to protrude inward in the left-right direction). can. On the other hand, since the connecting member is fixed to the outer surface (i.e., the first outer surface and the second outer surface) of each reinforcing plate, the edge connected to the first outer surface of the first end surface of the first reinforcing plate and the second A state in which the edge portion of the second end surface of the reinforcing plate connected to the second outer surface is in contact with (or in close proximity to) is maintained. That is, the first reinforcing plate is prevented from bending relative to the second reinforcing plate in the direction in which the first inner surface and the second inner surface approach each other (that is, the side wall portion is prevented from being bent so as to protrude outward in the left-right direction). Ru. Therefore, during the folding operation of the baby carriage, the side wall portions are prevented from being folded so as to expand outward in the left-right direction. Furthermore, the connecting member does not bias the first reinforcing plate and the second reinforcing plate so that the first reinforcing plate is bent relative to the second reinforcing plate in a direction that reduces the angle formed by the first outer surface and the second outer surface. The first reinforcing plate and the second reinforcing plate are connected in this manner. That is, in the unfolded state, the connecting member is configured not to encourage the side wall portion to bend so as to protrude inward in the left-right direction. As a result, in the unfolded state, the first reinforcing plate and the second reinforcing plate are in a parallel state (that is, the first end surface and the second end surface are in contact, and the first outer surface and the second outer surface are flush with each other). It is properly maintained to prevent the infant riding space from being compressed by the side walls.
　接続部材は、第１外面と第２外面とに跨がるように配置され、第１外面及び第２外面に貼付されたテープ部材を有してもよい。上記構成によれば、テープ部材によって第１補強板及び第２補強板を接続することにより、展開状態において、第１外面と第２外面とが面一となる状態をより確実に維持することができる。これにより、展開状態において第１端面に対して第２端面がずれてしまい、第１補強板と第２補強板とが互いに重なってしまうこと（その結果、折り畳み動作時に第１補強板が第２補強板に対して折れ曲がることが阻害されること）を防止することができる。 The connection member may be disposed so as to straddle the first outer surface and the second outer surface, and may include a tape member affixed to the first outer surface and the second outer surface. According to the above configuration, by connecting the first reinforcing plate and the second reinforcing plate with the tape member, it is possible to more reliably maintain the state in which the first outer surface and the second outer surface are flush with each other in the unfolded state. can. This causes the second end surface to shift relative to the first end surface in the unfolded state, causing the first reinforcing plate and the second reinforcing plate to overlap each other (as a result, during the folding operation, the first reinforcing plate This can prevent the reinforcing plate from being obstructed from bending.
　接続部材は、第１外面と第２外面とに跨がるように配置され、第１補強板及び第２補強板の各々に縫合された布部材を有してもよい。例えば、接続部材としてテープ部材を用いた場合には、経時的なテープ部材の粘着力の低下に起因して、テープ部材が第１外面又は第２外面から剥がれてしまうおそれがある。一方、接続部材として布部材を用いる上記構成によれば、各補強板の外面（第１外面及び第２外面）にあてがった布部材を各補強板に縫合することにより、第１補強板及び第２補強板から接続部材が外れてしまうことを防止し、第１補強板と第２補強板とをより安定的に接続することができる。 The connecting member may include a cloth member that is arranged to straddle the first outer surface and the second outer surface and is sewn to each of the first reinforcing plate and the second reinforcing plate. For example, when a tape member is used as the connecting member, there is a risk that the tape member may peel off from the first outer surface or the second outer surface due to a decrease in adhesive strength of the tape member over time. On the other hand, according to the above configuration in which a cloth member is used as a connecting member, by sewing the cloth member applied to the outer surface (the first outer surface and the second outer surface) of each reinforcing plate to each reinforcing plate, the first reinforcing plate and the second reinforcing plate It is possible to prevent the connecting member from coming off from the second reinforcing plate, and to connect the first reinforcing plate and the second reinforcing plate more stably.
　接続部材は、第１外面と第２外面とに跨がるように配置され、第１外面及び第２外面に貼付されたテープ部材と、第１外面と第２外面とに跨がるように配置され、第１補強板及び第２補強板の各々に縫合された布部材と、を有してもよい。上記構成によれば、上述したテープ部材及び布部材の両方の効果を得ることができる。すなわち、布部材を用いることによって、第１補強板と第２補強板とをより安定的に接続することができると共に、テープ部材を用いることによって、第１端面に対して第２端面がずれてしまうことを防止することができる。 The connecting member is arranged so as to straddle the first outer surface and the second outer surface, and the connecting member is arranged so as to straddle the tape member attached to the first outer surface and the second outer surface, and the first outer surface and the second outer surface. A cloth member may be arranged and sewn to each of the first reinforcing plate and the second reinforcing plate. According to the above configuration, the effects of both the tape member and the cloth member described above can be obtained. That is, by using the cloth member, the first reinforcing plate and the second reinforcing plate can be connected more stably, and by using the tape member, the second end surface can be prevented from shifting with respect to the first end surface. It is possible to prevent it from being put away.
　テープ部材と布部材とは、互いに重なる部分を有してもよく、上記部分において、テープ部材は、布部材と第１補強板及び第２補強板との間に配置されてもよい。上記構成によれば、テープ部材と布部材とが互いに重なる部分において、テープ部材を布部材で適切に保護することができる。すなわち、上記部分において、テープ部材の表面が外部に露出することが防止される。その結果、乳母車の使用時等に発生する外部からの衝撃等に起因するテープ部材の損傷を抑制し、第１外面又は第２外面からテープ部材が剥がれてしまうことを抑制することができる。 The tape member and the cloth member may have a portion that overlaps with each other, and in the portion, the tape member may be arranged between the cloth member and the first reinforcing plate and the second reinforcing plate. According to the above configuration, the tape member can be appropriately protected by the cloth member in the portion where the tape member and the cloth member overlap each other. That is, in the above portion, the surface of the tape member is prevented from being exposed to the outside. As a result, it is possible to suppress damage to the tape member due to external shocks generated during use of the baby carriage, and to suppress peeling of the tape member from the first outer surface or the second outer surface.
　テープ部材は、上記部分において、布部材と共に第１補強板及び第２補強板の各々に縫合されていてもよい。上記構成によれば、テープ部材が布部材と共に第１補強板及び第２補強板に対して強固に固定（縫合）されるため、第１外面又は第２外面からテープ部材が剥がれてしまうことをより効果的に抑制することができる。 The tape member may be sewn together with the cloth member to each of the first reinforcing plate and the second reinforcing plate in the above portion. According to the above configuration, since the tape member is firmly fixed (sewn) to the first reinforcing plate and the second reinforcing plate together with the cloth member, peeling of the tape member from the first outer surface or the second outer surface is prevented. It can be suppressed more effectively.
　第１補強板と第２補強板との境界に沿った布部材の長さは、境界に沿ったテープ部材の長さよりも長くてもよい。粘着材料を有するテープ部材を布部材及び各補強板と共に縫合する場合、縫合する際に用いられるミシン針等にテープ部材を構成する粘着材料が付着し、ミシンの動作異常等を引き起こすおそれがある。上記のように、布部材をテープ部材よりも長くすることにより、布部材が各補強板に縫合される全体領域に対して、テープ部材が布部材と共に縫合される領域の割合を小さくすることができる。その結果、上述したようなテープ部材の粘着材料に起因するトラブルの発生を抑制できる。 The length of the cloth member along the boundary between the first reinforcing plate and the second reinforcing plate may be longer than the length of the tape member along the boundary. When sewing a tape member containing an adhesive material together with a cloth member and each reinforcing plate, there is a risk that the adhesive material constituting the tape member may adhere to a sewing machine needle or the like used for sewing, causing abnormal operation of the sewing machine. As mentioned above, by making the cloth member longer than the tape member, it is possible to reduce the ratio of the area where the tape member is sewn together with the cloth member to the total area where the cloth member is sewn to each reinforcing plate. can. As a result, the occurrence of troubles caused by the adhesive material of the tape member as described above can be suppressed.
　側壁部は、内側生地と、内側生地よりも外側に配置された外側生地と、内側生地よりも外側且つ外側生地よりも内側に配置された内側補強生地と、外側生地よりも内側且つ内側補強生地よりも外側に配置された外側補強生地と、を有してもよく、第１補強板、第２補強板、及び接続部材は、内側補強生地と外側補強生地との間に収容されていてもよく、第１補強板及び第２補強板は、内側補強生地及び外側補強生地の少なくとも一方に固定されていてもよい。上記構成では、各補強板が内側補強生地と外側補強生地とで挟み込まれた状態で、さらにその外側が内側生地と外側生地とで覆われる。このように各補強板を二重の生地で保護することにより、側壁部に対して外部からの衝撃が加わった際に、側壁部のうち外部に露出した生地（内側生地及び外側生地）に破れ等が生じた場合でも、補強用生地（内側補強生地及び外側補強生地）によって各補強板が外部に露出することが防止される。その結果、補強板が外部に露出することによる見栄えの悪化、外部に露出した補強板と乳母車本体との接触等による補強板の破損等を防止することができる。 The side wall portion includes an inner fabric, an outer fabric placed outside the inner fabric, an inner reinforcing fabric placed outside the inner fabric and inside the outer fabric, and an inner reinforcing fabric placed inside the outer fabric and inside the outer fabric. The first reinforcing plate, the second reinforcing plate, and the connecting member may be housed between the inner reinforcing fabric and the outer reinforcing fabric. Often, the first reinforcing plate and the second reinforcing plate may be fixed to at least one of the inner reinforcing fabric and the outer reinforcing fabric. In the above configuration, each reinforcing plate is sandwiched between the inner reinforcing fabric and the outer reinforcing fabric, and the outside thereof is further covered with the inner fabric and the outer fabric. By protecting each reinforcing plate with double fabric in this way, when an external impact is applied to the side wall, the fabric exposed to the outside (inner fabric and outer fabric) of the side wall will be torn. Even if this occurs, each reinforcing plate is prevented from being exposed to the outside by the reinforcing fabrics (inner reinforcing fabric and outer reinforcing fabric). As a result, it is possible to prevent deterioration in appearance due to the reinforcing plate being exposed to the outside, and damage to the reinforcing plate due to contact between the reinforcing plate exposed to the outside and the main body of the baby carriage.

In the following description, the same or equivalent elements will be denoted by the same reference numerals, and overlapping description will be omitted.
　図１～図４を用いて、本実施形態に係る乳母車１について説明する。乳母車１は、折り畳み可能に構成されている。すなわち、乳母車１は、図１～図３に示される展開状態と図４に示される折り畳み状態とを切替可能に構成されている。展開状態とは、乳母車１に乳幼児を乗車させることができるように乳母車本体２が広げられた（展開された）状態である。折り畳み状態とは、乳母車１をコンパクトに収納するために乳母車本体２が折り畳まれた状態である。 A baby carriage 1 according to the present embodiment will be explained using FIGS. 1 to 4. The baby carriage 1 is configured to be foldable. That is, the baby carriage 1 is configured to be switchable between the unfolded state shown in FIGS. 1 to 3 and the folded state shown in FIG. 4. The unfolded state is a state in which the stroller body 2 is spread out (expanded) so that an infant can ride in the stroller 1. The folded state is a state in which the baby carriage body 2 is folded in order to store the baby carriage 1 compactly.
　本明細書中において、乳母車１に対する「前」、「後」、「左」、「右」、「上」、「下」、「前後方向」、「左右方向」、及び「上下方向」の用語は、特に説明がない場合、展開状態の乳母車１に乗車する乳幼児を基準とした「前」、「後」、「左」、「右」、「上」、「下」、「前後方向」、「左右方向」、及び「上下方向」を意味する。乳母車１の接地面が水平面である場合には、「前後方向」は、接地面に平行な乳母車１の進退方向である。また、「上下方向」は、前後方向に直交すると共に接地面に直交する方向である。また、「左右方向」は、前後方向及び上下方向の両方に直交する方向である。 In this specification, the terms "front", "rear", "left", "right", "top", "bottom", "front-back direction", "left-right direction", and "up-down direction" with respect to the baby carriage 1 are used. Unless otherwise specified, "front", "rear", "left", "right", "top", "bottom", "back and forth direction", based on the infant riding in the stroller 1 in the unfolded state, Means "left-right direction" and "up-down direction". When the ground plane of the baby carriage 1 is a horizontal plane, the "back and forth direction" is a direction in which the baby carriage 1 moves forward and backward parallel to the ground plane. Moreover, the "vertical direction" is a direction that is perpendicular to the front-rear direction and perpendicular to the ground plane. Moreover, the "left-right direction" is a direction perpendicular to both the front-back direction and the up-down direction.
　図１～図４において、「前後方向」をＸ軸方向と表し、「左右方向」をＹ軸方向と表し、「上下方向」をＺ軸方向と表す。Ｘ軸方向の負方向側が「前」に相当し、Ｘ軸方向の正方向側が「後」に相当する。また、Ｙ軸方向の正方向が「右」に相当し、Ｙ軸方向の負方向側が「左」に相当する。また、Ｚ軸方向の正方向が「上」に相当し、Ｚ軸方向の負方向が「下」に相当する。なお、「左右方向」において、乳母車１に乗車する乳幼児（乳母車１の左右方向の中心）に接近する側を内側といい、乳幼児から離間する側を外側という。 In FIGS. 1 to 4, the "front-back direction" is expressed as the X-axis direction, the "left-right direction" is expressed as the Y-axis direction, and the "up-down direction" is expressed as the Z-axis direction. The negative side in the X-axis direction corresponds to the "front", and the positive side in the X-axis direction corresponds to the "rear". Further, the positive direction in the Y-axis direction corresponds to "right", and the negative direction in the Y-axis direction corresponds to "left". Further, the positive direction in the Z-axis direction corresponds to "up", and the negative direction in the Z-axis direction corresponds to "down". In addition, in the "left-right direction", the side that approaches the infant riding in the baby carriage 1 (the center of the baby carriage 1 in the left-right direction) is referred to as the inside, and the side that is separated from the infant is referred to as the outside.
　図１及び図２に示されるように、乳母車１は、乳母車本体２と、乳母車本体２に装着されるシート３（乳母車用シート）と、を備える。乳母車本体２は、本体フレーム１０と、本体フレーム１０に接続されたハンドル２０及びシート支持部３０と、を有している。図１及び図２は、いずれも展開状態の乳母車１を示す斜視図である。図１は、シート３が乳母車本体２に装着された状態を示す図であり、図２は、シート３が乳母車本体２から取り外された状態を示す図である。 As shown in FIGS. 1 and 2, the baby carriage 1 includes a baby carriage body 2 and a seat 3 (baby carriage seat) attached to the baby carriage body 2. The baby carriage body 2 includes a body frame 10, a handle 20 and a seat support portion 30 connected to the body frame 10. 1 and 2 are perspective views showing the baby carriage 1 in the unfolded state. FIG. 1 is a diagram showing a state in which the seat 3 is attached to the baby carriage main body 2, and FIG. 2 is a diagram showing a state in which the seat 3 is removed from the baby carriage main body 2.
　本体フレーム１０は、それぞれ左右両側に設けられた、一対の前脚１１と、一対の後脚１２と、一対のアームレスト１３と、を有している。各前脚１１の上端部は、各前脚１１に対応する側（左側又は右側）に配置されたアームレスト１３の前端部に回動可能に接続されている。同様に、各後脚１２の上端部は、各後脚１２に対応する側（左側又は右側）に配置されたアームレスト１３の前端部に回動可能に接続されている。各アームレスト１３の後端部は、リンク部材１４及び回動ブラケット１５を介して、各アームレスト１３に対応する側（左側又は右側）に配置された後脚１２の中間部分に接続されている。リンク部材１４の上端部には、後述する側壁部８０に設けられた連結部材１０１を連結するための突起部１４ａが設けられている。突起部１４ａは、リンク部材１４と平行に上方に延びるピン状に形成されている。 The main body frame 10 has a pair of front legs 11, a pair of rear legs 12, and a pair of armrests 13, which are provided on both left and right sides, respectively. The upper end of each front leg 11 is rotatably connected to the front end of an armrest 13 disposed on the side corresponding to each front leg 11 (left side or right side). Similarly, the upper end of each rear leg 12 is rotatably connected to the front end of an armrest 13 disposed on the side corresponding to each rear leg 12 (left side or right side). The rear end portion of each armrest 13 is connected via a link member 14 and a rotation bracket 15 to an intermediate portion of a rear leg 12 disposed on the side corresponding to each armrest 13 (left side or right side). A projection 14a is provided at the upper end of the link member 14 for connecting a connecting member 101 provided on a side wall 80, which will be described later. The protrusion 14a is formed into a pin shape that extends upward in parallel with the link member 14.
　ハンドル２０は、上記のように構成された本体フレーム１０に対して、揺動可能に接続されている。図１及び図２に示されるように、ハンドル２０は、Ｕ字状に形成されている。図１～図３に示される背面押し状態（すなわち、操作者（保護者）が乳母車１に乗車する乳幼児の背面側からハンドル２０を把持して乳母車１を操縦する状態）において、ハンドル２０の両端の各部分は、各部分に対応する側（左側又は右側）のリンク部材１４に対して、リンク部材１４と平行な状態が維持されるように連結されている。なお、ハンドル２０は、ハンドル２０の持ち手の部分が乳母車１に乗車する乳幼児の前方に移動するように、本体フレーム１０に対して図３における反時計回りに揺動可能に構成されてもよい。この場合、操作者は、乳幼児に対面する前脚１１側の位置からハンドル２０を把持して乳母車を操縦することが可能となる。すなわち、乳母車１の後脚１２側が進行方向の前方となるようにして乳母車１を走行させることが可能となる。このような対面押し状態においては、ハンドル２０はリンク部材１４とは非平行になる。ハンドル２０の中央部には、展開状態と折り畳み状態とを切り替える操作を行うための操作部２０ａが設けられている。操作部２０ａの操作により、展開状態又は折り畳み状態を維持するためのロック状態と、展開状態と折り畳み状態とを切り替え可能なアンロック状態と、を切り替えることができる。 The handle 20 is swingably connected to the main body frame 10 configured as described above. As shown in FIGS. 1 and 2, the handle 20 is formed in a U-shape. In the rear pushing state shown in FIGS. 1 to 3 (i.e., the state in which the operator (guardian) grips the handle 20 from the back side of the infant riding in the stroller 1 and operates the stroller 1), both ends of the handle 20 Each part is connected to the link member 14 on the side corresponding to each part (left side or right side) so that the state parallel to the link member 14 is maintained. Note that the handle 20 may be configured to be able to swing counterclockwise in FIG. 3 with respect to the main body frame 10 so that the handle portion of the handle 20 moves in front of the infant riding in the baby carriage 1. . In this case, the operator can operate the baby carriage by grasping the handle 20 from a position on the side of the front legs 11 facing the infant. That is, it is possible to run the baby carriage 1 with the rear leg 12 side of the baby carriage 1 facing forward in the traveling direction. In such a facing state, the handle 20 becomes non-parallel to the link member 14. An operating section 20a is provided at the center of the handle 20 for performing an operation for switching between the unfolded state and the folded state. By operating the operating unit 20a, it is possible to switch between a locked state in which the unfolded state or the folded state is maintained, and an unlocked state in which the unfolded state and the folded state can be switched.
　乳母車１は、以下のようにして、各構成部材を互いに回動させることにより、展開状態（図１～図３参照）から折り畳み状態（図４参照）へと折り畳むことができる。 The baby carriage 1 can be folded from the unfolded state (see FIGS. 1 to 3) to the folded state (see FIG. 4) by rotating each component relative to each other as follows.
　本実施形態では一例として、図１～図３に示される展開状態の乳母車１を折り畳む際には、操作部２０ａを操作してアンロック状態にしつつ、ハンドル２０を一旦上方に引き上げ、その後、下方に押し下げる操作が実行される。上記の折り畳み操作に伴い、リンク部材１４及び回動ブラケット１５が後脚１２から離間し、回動ブラケット１５が後脚１２に対して、図３及び図４における時計回り方向に回動する。また、この動作に伴って、アームレスト１３及び座面支持フレーム３１が、リンク部材１４に対して、図３及び図４における時計回り方向に回動する。なお、リンク部材１４は、ハンドル２０と平行に配置されるため、図３及び図４においてハンドル２０の奥側に隠れている。 In this embodiment, as an example, when folding the baby stroller 1 in the unfolded state shown in FIGS. 1 to 3, the handle 20 is first pulled upward while operating the operating part 20a to be in the unlocked state, and then the handle 20 is pulled downward. The operation of pressing down is executed. With the above folding operation, the link member 14 and the rotating bracket 15 are separated from the rear leg 12, and the rotating bracket 15 rotates in the clockwise direction in FIGS. 3 and 4 with respect to the rear leg 12. Further, along with this movement, the armrest 13 and the seat support frame 31 rotate clockwise in FIGS. 3 and 4 with respect to the link member 14. In addition, since the link member 14 is arranged parallel to the handle 20, it is hidden behind the handle 20 in FIGS. 3 and 4.
　図４に示されるように、上記の折り畳み操作により、乳母車１を折り畳むことができる。図４に示されるように、乳母車１を折り畳み状態にすることにより、乳母車１の前後方向（Ｘ軸方向）の寸法を、展開状態における乳母車１の前後方向（Ｘ軸方向）の寸法よりも小型化することができる。なお、乳母車１を折り畳み状態から展開するには、上記の折り畳み操作とは逆の操作を実行すればよい。 As shown in FIG. 4, the baby carriage 1 can be folded by the above folding operation. As shown in FIG. 4, by putting the baby carriage 1 in the folded state, the size of the baby carriage 1 in the front-rear direction (X-axis direction) is smaller than the size of the baby carriage 1 in the front-rear direction (X-axis direction) in the unfolded state. can be converted into In addition, in order to unfold the baby carriage 1 from the folded state, it is sufficient to perform an operation opposite to the above-mentioned folding operation.
　図２に示されるように、シート支持部３０は、リクライニング可能にシート３を支持する。シート支持部３０は、座面支持フレーム３１と、背当支持フレーム３２と、ベースシート３３と、上方フレーム３４と、連結フレーム３５と、を有している。 As shown in FIG. 2, the seat support section 30 supports the seat 3 in a reclining manner. The seat support section 30 includes a seat support frame 31 , a back support frame 32 , a base seat 33 , an upper frame 34 , and a connection frame 35 .
　座面支持フレーム３１は、乳母車１に乗車した乳幼児の臀部の下方に位置するフレーム部材である。背当支持フレーム３２は、座面支持フレーム３１に揺動可能に接続され、乳母車１に乗車した乳幼児の背中の背後に位置する部分である。例えば、座面支持フレーム３１及び背当支持フレーム３２の各々は、全体としてＵ字状の形状を有する金属製のパイプによって構成され得る。 The seat support frame 31 is a frame member located below the buttocks of an infant riding in the baby carriage 1. The back support frame 32 is a part that is swingably connected to the seat support frame 31 and is located behind the back of the infant riding in the baby carriage 1. For example, each of the seat support frame 31 and the back support frame 32 may be formed of a metal pipe having an overall U-shape.
　ベースシート３３は、座面支持フレーム３１及び背当支持フレーム３２に張設された布部材である。ベースシート３３は、後述するシート３の座面部４０を支持する座面支持部３３１と、後述するシート３の背当部５０を支持する背当支持部３３２と、を有している。 The base sheet 33 is a cloth member stretched between the seat support frame 31 and the back support frame 32. The base seat 33 has a seat support part 331 that supports a seat part 40 of the seat 3, which will be described later, and a back support part 332, which supports a back part 50 of the seat 3, which will be described later.
　上方フレーム３４は、背当支持フレーム３２よりも上方位置において、背当支持フレーム３２と略平行に配置されるＵ字状のフレーム部材である。連結フレーム３５は、背当支持フレーム３２と上方フレーム３４とを連結するフレーム部材である。 The upper frame 34 is a U-shaped frame member arranged substantially parallel to the back support frame 32 at a position above the back support frame 32. The connection frame 35 is a frame member that connects the back support frame 32 and the upper frame 34.
　図５及び図６を用いて、シート支持部３０に装着されるシート３について説明する。図５は、座面部４０と背当部５０とが平行になるように伸ばされた状態のシート３を表面４ａ側（乳幼児が乗車する側）から見た平面図であり、図６は、図５と同様の状態のシート３を裏面４ｂ側から見た平面図である。 The seat 3 attached to the seat support section 30 will be explained using FIGS. 5 and 6. FIG. 5 is a plan view of the seat 3 in a state where it is stretched so that the seat surface part 40 and the backrest part 50 are parallel to each other, viewed from the surface 4a side (the side on which an infant rides), and FIG. FIG. 5 is a plan view of the sheet 3 in the same state as No. 5 as viewed from the back surface 4b side.
　シート３は、例えば、クッション性を有する素材によって構成され、シート３の表面４ａ側に着座する乳幼児に快適な乗り心地を提供する。シート３は、座面部４０と、背当部５０と、包囲部６０と、フード部７０と、一対の側壁部８０と、を有している。 The seat 3 is made of, for example, a material with cushioning properties, and provides a comfortable ride for infants seated on the surface 4a side of the seat 3. The seat 3 includes a seat portion 40, a backrest portion 50, a surrounding portion 60, a hood portion 70, and a pair of side wall portions 80.
　座面部４０は、座面支持フレーム３１に保持されたベースシート３３の座面支持部３３１によって支持され、乳母車１に乗車する乳幼児の臀部を主に支持する。 The seat portion 40 is supported by the seat support portion 331 of the base seat 33 held by the seat support frame 31, and mainly supports the buttocks of the infant riding in the baby carriage 1.
　背当部５０は、座面部４０に接続され、座面部４０の後方に位置している。背当部５０は、背当支持フレーム３２に保持されたベースシート３３の背当支持部３３２によって支持され、乳母車１に乗車する乳幼児の背中に対面する位置に配置される。 The backrest part 50 is connected to the seat part 40 and is located at the rear of the seat part 40. The back support part 50 is supported by the back support part 332 of the base sheet 33 held by the back support frame 32, and is arranged at a position facing the back of the infant riding in the baby carriage 1.
　座面部４０と背当部５０とは、例えば、互いに縫い付けられることによって接続されている。この場合、座面部４０と背当部５０との間には、縫い目からなる接続ラインＬ１が形成される。乳母車１のリクライニング動作又は折り畳み動作に伴って、座面部４０及び背当部５０は、互いに接近する。この際、座面部４０及び背当部５０は、上記接続ラインＬ１を揺動軸線として、相対的に揺動する。 The seat portion 40 and the backrest portion 50 are connected, for example, by being sewn together. In this case, a connection line L1 consisting of a seam is formed between the seat portion 40 and the backrest portion 50. As the baby carriage 1 reclines or folds, the seat portion 40 and the backrest portion 50 approach each other. At this time, the seat portion 40 and the backrest portion 50 swing relative to each other about the connection line L1 as a swing axis.
　包囲部６０は、背当部５０の座面部４０に接続される縁部（接続ラインＬ１）以外の縁部に接続されている。包囲部６０は、乳母車１に乗車する乳幼児の上半身の上方及び側方を覆って保護する部分である。すなわち、包囲部６０は、乳幼児の頭部を保護するヘッドレストとして機能する部分を含む。包囲部６０は、例えば、背当部５０に縫い付けられており、背当部５０と包囲部６０との接続箇所は、略Ｕ字状の縫製ラインによって画成される。 The surrounding part 60 is connected to an edge of the backrest part 50 other than the edge connected to the seat surface part 40 (connection line L1). The enclosing part 60 is a part that covers and protects the upper and lateral sides of the upper body of an infant riding in the baby carriage 1. That is, the enclosing portion 60 includes a portion that functions as a headrest that protects the infant's head. For example, the surrounding part 60 is sewn to the back rest part 50, and the connection point between the back part 50 and the surrounding part 60 is defined by a substantially U-shaped sewing line.
　フード部７０は、包囲部６０の背当部５０に接続される側とは反対側の縁部に接続され、包囲部６０の裏面側を覆うフード状に設けられた部材である。図１に示されるように、シート３がシート支持部３０に装着される際には、包囲部６０とフード部７０との接続箇所が上方フレーム３４（図２参照）に沿うように配置されて、フード部７０が、上方フレーム３４及び連結フレーム３５を覆うように被せられる。これにより、包囲部６０が安定的に固定される。 The hood part 70 is a hood-shaped member that is connected to the edge of the enveloping part 60 on the side opposite to the side connected to the back support part 50 and covers the back side of the enveloping part 60. As shown in FIG. 1, when the seat 3 is attached to the seat support section 30, the connection point between the surrounding section 60 and the hood section 70 is arranged along the upper frame 34 (see FIG. 2). , a hood portion 70 is placed over the upper frame 34 and the connecting frame 35. Thereby, the surrounding portion 60 is stably fixed.
　一対の側壁部８０は、展開状態における左右方向（Ｙ軸方向）の座面部４０の両側に配置されている。側壁部８０は、座面部４０と背当部５０とに架け渡されており、乳母車１に乗車した乳幼児を側方から保護する役割を果たす。側壁部８０は、展開状態（図１参照）において、シート支持部３０に直接支持されることなく、座面部４０に対して略垂直に起立した状態を維持するように構成されている。 The pair of side wall portions 80 are arranged on both sides of the seat surface portion 40 in the left-right direction (Y-axis direction) in the unfolded state. The side wall portion 80 spans the seat portion 40 and the backrest portion 50, and serves to protect the infant riding in the baby carriage 1 from the side. The side wall portion 80 is configured to maintain an upright state substantially perpendicular to the seat surface portion 40 without being directly supported by the seat support portion 30 in the unfolded state (see FIG. 1).
　各側壁部８０の座面部４０及び背当部５０から離間する側の端部には、展開状態においてリンク部材１４の突起部１４ａに向かって延びる突出部８５が設けられている。突出部８５の裏面４ｂには、突起部１４ａに連結される連結部材１０１が設けられている。一例として、連結部材１０１は、突出部８５に対して固定されたベルト部１０１ａと、ベルト部１０１ａの両端に設けられた一対のホック１０１ｂ（互いに嵌合するように構成されたホック対）と、を有するホックベルトである。ベルト部１０１ａを突起部１４ａの側面に巻き付け、一対のホック１０１ｂ同士（すなわち、凹部と凸部同士）を互いに留めることにより、図１に示されるように、連結部材１０１が突起部１４ａに対して固定される。これにより、展開状態における側壁部８０の起立姿勢が安定化する。 A protrusion 85 that extends toward the protrusion 14a of the link member 14 in the unfolded state is provided at the end of each side wall 80 on the side away from the seat surface 40 and the backrest 50. A connecting member 101 connected to the protrusion 14a is provided on the back surface 4b of the protrusion 85. As an example, the connecting member 101 includes a belt portion 101a fixed to the protrusion 85, a pair of hooks 101b (a pair of hooks configured to fit into each other) provided at both ends of the belt portion 101a, It is a hook belt with By wrapping the belt portion 101a around the side surface of the protrusion 14a and fastening the pair of hooks 101b (that is, the concave portion and the convex portion) to each other, the connecting member 101 is attached to the protrusion 14a as shown in FIG. Fixed. This stabilizes the standing posture of the side wall portion 80 in the unfolded state.
　シート３は、座面部４０と背当部５０とが接続される境界部（接続ラインＬ１）の近傍（本実施形態では、接続ラインＬ１の左右方向（Ｙ軸方向）の両端部の近傍）に設けられた連結部材１０２（図６参照）を有している。連結部材１０２は、連結部材１０１と同様の構成を有している。連結部材１０２は、シート３の裏面４ｂに対して固定されたベルト部１０２ａと、ベルト部１０２ａの両端に設けられた一対のホック１０２ｂと、を有するホックベルトである。ベルト部１０２ａをリンク部材１４の側面に巻き付け、一対のホック１０２ｂ同士（すなわち、凹部と凸部同士）を互いに留めることにより、図１に示されるように、連結部材１０２がリンク部材１４に対して固定される。これにより、連結部材１０２によってシート３をシート支持部３０に固定しつつ、シート３の座面部４０と背当部５０との間の境界部（接続ラインＬ１）を適正な位置に合わせることができる。 The seat 3 is located near the boundary (connection line L1) where the seat portion 40 and the backrest 50 are connected (in the present embodiment, near both ends of the connection line L1 in the left-right direction (Y-axis direction)). It has a connecting member 102 (see FIG. 6) provided therein. The connecting member 102 has the same configuration as the connecting member 101. The connecting member 102 is a hook belt having a belt portion 102a fixed to the back surface 4b of the sheet 3, and a pair of hooks 102b provided at both ends of the belt portion 102a. By wrapping the belt portion 102a around the side surface of the link member 14 and fastening the pair of hooks 102b (that is, the concave portion and the convex portion) to each other, the connecting member 102 is attached to the link member 14 as shown in FIG. Fixed. Thereby, while fixing the seat 3 to the seat support part 30 by the connecting member 102, the boundary part (connection line L1) between the seat surface part 40 and the backrest part 50 of the seat 3 can be adjusted to an appropriate position. .
　なお、シート３は、連結部材１０１，１０２以外の図示しない固定具によってシート支持部３０（例えばベースシート３３）に対して更に固定されてもよい。 Note that the seat 3 may be further fixed to the seat support portion 30 (for example, the base sheet 33) by a fixing member (not shown) other than the connecting members 101 and 102.
　乳母車１に乗車する乳幼児に直接接触し得る座面部４０、背当部５０、及び包囲部６０は、例えば、クッション性を有する布材を用いて構成され得る。このような布材の具体例としては、スポンジ等の材料を２つの布地で挟んでなる布材、クッション性を有する布地そのものからなる布材等が挙げられる。また、側壁部８０のうち少なくとも左右方向の内側に配置される部分（後述する内側生地８０１）も、乳幼児に直接接触し得るため、クッション性を有する布材によって構成され得る。 The seat portion 40, the backrest portion 50, and the surrounding portion 60, which can come into direct contact with the infant riding in the baby carriage 1, may be constructed using, for example, a cloth material having cushioning properties. Specific examples of such cloth materials include cloth materials made by sandwiching a material such as sponge between two cloth materials, and cloth materials made of cloth itself having cushioning properties. Furthermore, at least a portion of the side wall portion 80 disposed on the inside in the left-right direction (inner fabric 801 to be described later) can also be made of a cloth material having cushioning properties, since it can come into direct contact with an infant.
　次に、シート３が備える一対の側壁部８０の構成について詳細に説明する。各側壁部８０の構成は互いに同一であるため、以降の説明では、左側に配置される側壁部８０に着目して説明する。図５及び図６に示されるように、側壁部８０は、縁部８０ａ，８０ｂ，８０ｃによって画定される略扇形状を有している。縁部８０ａは、側壁部８０と座面部４０及び背当部５０との境界に沿った縁部である。縁部８０ｂは、縁部８０ａの後端部８０ａ１（背当部５０に接続される端部）から背当部５０の縁部５１に対して略垂直な方向に延びる縁部である。上述した突出部８５は、縁部８０ｂの外側に設けられている。縁部８０ｃは、縁部８０ａの前端部８０ａ２から縁部８０ｂの外側端部まで弧状に延びる縁部である。 Next, the configuration of the pair of side wall portions 80 included in the seat 3 will be described in detail. Since the configuration of each side wall portion 80 is the same, the following description will focus on the side wall portion 80 disposed on the left side. As shown in FIGS. 5 and 6, the side wall portion 80 has a substantially fan shape defined by edges 80a, 80b, and 80c. The edge 80a is an edge along the boundary between the side wall 80, the seat surface 40, and the backrest 50. The edge 80b is an edge extending from the rear end 80a1 (the end connected to the back rest 50) of the edge 80a in a direction substantially perpendicular to the edge 51 of the back rest 50. The above-mentioned protrusion 85 is provided on the outside of the edge 80b. The edge 80c is an edge extending in an arc from the front end 80a2 of the edge 80a to the outer end of the edge 80b.
　図７～図９に示されるように、側壁部８０は、補強板８１（第１補強板）と、補強板８２（第２補強板）と、接続部材８３と、を有する。図７は、展開状態において補強板８１、補強板８２、及び接続部材８３を左右方向（Ｙ軸方向）の外側から見た平面図である。図８は、図７のＶＩＩＩ－ＶＩＩＩ線に沿った断面図である。図９は、展開状態から折り畳み状態に移行する際の補強板８１，８２及び接続部材８３を模式的に示す図である。 As shown in FIGS. 7 to 9, the side wall portion 80 includes a reinforcing plate 81 (first reinforcing plate), a reinforcing plate 82 (second reinforcing plate), and a connecting member 83. FIG. 7 is a plan view of the reinforcing plate 81, the reinforcing plate 82, and the connecting member 83 viewed from the outside in the left-right direction (Y-axis direction) in the unfolded state. FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 7. FIG. 9 is a diagram schematically showing the reinforcing plates 81, 82 and the connecting member 83 when transitioning from the unfolded state to the folded state.
　図５に示されるように、補強板８１は、縁部８０ａに沿った領域に配置されている。補強板８１は、側壁部８０の他の箇所（側壁部８０を構成する後述する各生地）よりも変形しにくい（剛性の高い）部材である。補強板８１は、例えばポリプロピレン等の樹脂によって形成された板状の部材である。補強板８２は、補強板８１に対して座面部４０が位置する側とは反対側に配置されている。補強板８２は、例えば、補強板８１と同様の材料によって形成された板状の部材である。 As shown in FIG. 5, the reinforcing plate 81 is arranged in a region along the edge 80a. The reinforcing plate 81 is a member that is less likely to deform (has higher rigidity) than other parts of the side wall portion 80 (each of the later-described fabrics forming the side wall portion 80). The reinforcing plate 81 is a plate-shaped member made of resin such as polypropylene. The reinforcing plate 82 is arranged on the opposite side of the reinforcing plate 81 from the side where the seat portion 40 is located. The reinforcing plate 82 is, for example, a plate-shaped member made of the same material as the reinforcing plate 81.
　補強板８１と補強板８２とは、互いに接触しており、展開状態において互いに平行となるように配置されている。補強板８１と補強板８２との境目によって、接続ラインＬ１と縁部８０ａとが交わる端部（すなわち、座面部４０、背当部５０、及び側壁部８０の境界部）から縁部８０ｃの略中央部まで直線状に延びる折り目ラインＬ２が形成されている。補強板８１は、縁部８０ａと折り目ラインＬ２との間の領域に配置されている。補強板８２は、折り目ラインＬ２と縁部８０ｂとの間の領域に配置されている。図１０に示されるように、折り畳み状態において、側壁部８０は、左右方向（Ｙ軸方向）の内側に突出するように、折り目ラインＬ２に沿って二つ折りにされる。図１０は、折り畳み状態の乳母車１の平面図である。 The reinforcing plate 81 and the reinforcing plate 82 are in contact with each other and are arranged parallel to each other in the unfolded state. By the boundary between the reinforcing plate 81 and the reinforcing plate 82, from the end where the connection line L1 and the edge 80a intersect (i.e., the boundary between the seat surface part 40, the backrest part 50, and the side wall part 80) to the approximate edge 80c. A fold line L2 is formed that extends linearly to the center. The reinforcing plate 81 is arranged in a region between the edge 80a and the fold line L2. The reinforcing plate 82 is arranged in the area between the fold line L2 and the edge 80b. As shown in FIG. 10, in the folded state, the side wall portion 80 is folded in half along the crease line L2 so as to protrude inward in the left-right direction (Y-axis direction). FIG. 10 is a plan view of the baby carriage 1 in a folded state.
　補強板８１は、内面８１ａ（第１内面）と、外面８１ｂ（第１外面）と、端面８１ｃ（第１端面）と、を有している。内面８１ａは、展開状態において、左右方向（Ｙ軸方向）において座面部４０が位置する側を向く面である。外面８１ｂは、内面８１ａとは反対側の面である。端面８１ｃは、内面８１ａと外面８１ｂとを接続する面である。端面８１ｃは、内面８１ａ及び外面８１ｂに対して垂直に延びる面である。端面８１ｃは、展開状態（すなわち、補強板８１と補強板８２とが平行に配置された状態）において、補強板８２の端面８２ｃと対向及び接触する。内面８１ａ、外面８１ｂ、及び端面８１ｃは、いずれも平坦面である。 The reinforcing plate 81 has an inner surface 81a (first inner surface), an outer surface 81b (first outer surface), and an end surface 81c (first end surface). The inner surface 81a is a surface facing toward the side where the seat portion 40 is located in the left-right direction (Y-axis direction) in the unfolded state. The outer surface 81b is a surface opposite to the inner surface 81a. The end surface 81c is a surface connecting the inner surface 81a and the outer surface 81b. The end surface 81c is a surface extending perpendicularly to the inner surface 81a and the outer surface 81b. The end surface 81c faces and contacts the end surface 82c of the reinforcing plate 82 in the unfolded state (that is, the state in which the reinforcing plate 81 and the reinforcing plate 82 are arranged in parallel). The inner surface 81a, the outer surface 81b, and the end surface 81c are all flat surfaces.
　補強板８２は、内面８２ａ（第２内面）と、外面８２ｂ（第２外面）と、端面８２ｃ（第２端面）と、を有している。内面８２ａは、展開状態において、左右方向（Ｙ軸方向）において座面部４０が位置する側を向く面である。内面８２ａは、展開状態において、補強板８１の内面８１ａと面一に連続する面である。外面８２ｂは、内面８２ａとは反対側の面である。外面８２ｂは、展開状態において、補強板８１の外面８１ｂと面一に連続する面である。端面８２ｃは、内面８２ａと外面８２ｂとを接続する面である。端面８２ｃは、内面８２ａ及び外面８２ｂに対して垂直に延びる面である。端面８２ｃは、展開状態において、補強板８１の端面８１ｃと対向及び接触する。内面８２ａ、外面８２ｂ、及び端面８２ｃは、いずれも平坦面である。 The reinforcing plate 82 has an inner surface 82a (second inner surface), an outer surface 82b (second outer surface), and an end surface 82c (second end surface). The inner surface 82a is a surface facing toward the side where the seat portion 40 is located in the left-right direction (Y-axis direction) in the unfolded state. The inner surface 82a is a surface that is flush with and continuous with the inner surface 81a of the reinforcing plate 81 in the unfolded state. The outer surface 82b is a surface opposite to the inner surface 82a. The outer surface 82b is a surface that continues flush with the outer surface 81b of the reinforcing plate 81 in the unfolded state. The end surface 82c is a surface connecting the inner surface 82a and the outer surface 82b. The end surface 82c is a surface extending perpendicularly to the inner surface 82a and the outer surface 82b. The end surface 82c faces and contacts the end surface 81c of the reinforcing plate 81 in the unfolded state. The inner surface 82a, the outer surface 82b, and the end surface 82c are all flat surfaces.
　接続部材８３は、補強板８１と補強板８２とを接続する部材である。接続部材８３は、補強板８１と補強板８２とに跨がるように、補強板８１の外面８１ｂと補強板８２の外面８２ｂとに固定されている。接続部材８３は、少なくとも補強板８１と補強板８２との境界である折り目ラインＬ２に沿って折り曲げ可能に構成されている。本実施形態では、接続部材８３は、全体として柔軟な素材によって形成されることによって、折り目ラインＬ２に沿って折り曲げ可能とされている。 The connecting member 83 is a member that connects the reinforcing plate 81 and the reinforcing plate 82. The connecting member 83 is fixed to the outer surface 81b of the reinforcing plate 81 and the outer surface 82b of the reinforcing plate 82 so as to span the reinforcing plate 81 and the reinforcing plate 82. The connecting member 83 is configured to be bendable at least along a crease line L2 that is a boundary between the reinforcing plate 81 and the reinforcing plate 82. In this embodiment, the connecting member 83 is made of a flexible material as a whole, so that it can be bent along the fold line L2.
　接続部材８３は、外面８１ｂと外面８２ｂとがなす角度が減少する方向（すなわち、外面８１ｂと外面８２ｂとが互いに接近する方向）に補強板８１が補強板８２に対して折れ曲がるように補強板８１及び補強板８２を付勢しない態様で、外面８１ｂ及び外面８２ｂに固定されている。例えば、接続部材８３を外面８１ｂ及び外面８２ｂの面内方向に沿って収縮するゴム等の弾性部材によって構成した場合、接続部材８３の収縮力によって、外面８１ｂと外面８２ｂとが互いに接近する方向に折れ曲がるように、補強板８１及び補強板８２が付勢されてしまう。その結果、展開状態において、外面８１ｂ及び外面８２ｂがなす角度が１８０度よりも小さくなるように、補強板８１が補強板８２に対して傾斜するおそれがある。すなわち、展開状態において、側壁部８０が左右方向（Ｙ軸方向）の内側へと若干突出するおそれがある。これに対して、本実施形態の接続部材８３は、上記のように外面８１ｂと外面８２ｂとが互いに接近する方向に補強板８１が補強板８２に対して折れ曲がることを助長しないように構成されている。すなわち、接続部材８３は、外面８１ｂ及び外面８２ｂの面内方向に沿って収縮しない部材によって構成されている。本実施形態では、接続部材８３は、テープ部材８３１と、布部材８３２と、によって構成されている。 The connecting member 83 is configured such that the reinforcing plate 81 is bent with respect to the reinforcing plate 82 in a direction in which the angle formed by the outer surface 81b and the outer surface 82b decreases (that is, in a direction in which the outer surface 81b and the outer surface 82b approach each other). and is fixed to the outer surface 81b and the outer surface 82b in a manner that does not bias the reinforcing plate 82. For example, if the connecting member 83 is made of an elastic member such as rubber that contracts along the in-plane direction of the outer surfaces 81b and 82b, the contractile force of the connecting member 83 causes the outer surfaces 81b and 82b to approach each other. The reinforcing plates 81 and 82 are biased so as to bend. As a result, in the unfolded state, the reinforcing plate 81 may be inclined with respect to the reinforcing plate 82 so that the angle formed by the outer surface 81b and the outer surface 82b becomes smaller than 180 degrees. That is, in the unfolded state, the side wall portion 80 may protrude slightly inward in the left-right direction (Y-axis direction). In contrast, the connecting member 83 of the present embodiment is configured so as not to encourage the reinforcing plate 81 to bend relative to the reinforcing plate 82 in the direction in which the outer surface 81b and the outer surface 82b approach each other as described above. There is. That is, the connecting member 83 is made of a member that does not contract along the in-plane direction of the outer surface 81b and the outer surface 82b. In this embodiment, the connection member 83 includes a tape member 831 and a cloth member 832.
　テープ部材８３１は、外面８１ｂと外面８２ｂとに跨がるように配置され、外面８１ｂ及び外面８２ｂに貼付されている。テープ部材８３１は、例えば、繊維補強されたテープ（例えば、フィラメントテープ等）によって構成され得る。図７に示されるように、テープ部材８３１は、矩形状に形成されている。テープ部材８３１は、テープ部材８３１の幅方向Ｄ２（端面８１ｃと端面８２ｃとが対向する方向）の中心が折り目ラインＬ２と略一致するように、折り目ラインＬ２に沿って延びている。テープ部材８３１の折り目ラインＬ２に沿った方向Ｄ１の長さは、テープ部材８３１の幅方向Ｄ２の長さよりも長い。本実施形態では、テープ部材８３１は、方向Ｄ１における補強板８１，８２の端部から離間している。 The tape member 831 is arranged so as to straddle the outer surface 81b and the outer surface 82b, and is attached to the outer surface 81b and the outer surface 82b. The tape member 831 may be configured by, for example, a fiber-reinforced tape (eg, filament tape, etc.). As shown in FIG. 7, the tape member 831 is formed in a rectangular shape. The tape member 831 extends along the crease line L2 such that the center of the tape member 831 in the width direction D2 (the direction in which the end surfaces 81c and 82c face each other) substantially coincides with the crease line L2. The length of the tape member 831 in the direction D1 along the fold line L2 is longer than the length of the tape member 831 in the width direction D2. In this embodiment, the tape member 831 is spaced apart from the ends of the reinforcing plates 81 and 82 in the direction D1.
　上記のようにテープ部材８３１が設けられることにより、補強板８１の外面８１ｂ及び端面８１ｃの間の縁部８１ｄ（図９参照）と、補強板８２の外面８２ｂ及び端面８２ｃの間の縁部８２ｄ（図９参照）とが接触するように、補強板８１及び補強板８２を互いに固定することができる。すなわち、テープ部材８３１によって、上記縁部８１ｄ，８２ｄ同士の位置合わせを容易且つ精度良く行うことができる。 By providing the tape member 831 as described above, the edge 81d between the outer surface 81b and the end surface 81c of the reinforcing plate 81 (see FIG. 9) and the edge 82d between the outer surface 82b and the end surface 82c of the reinforcing plate 82 (See FIG. 9) The reinforcing plate 81 and the reinforcing plate 82 can be fixed to each other so that they are in contact with each other. That is, the tape member 831 allows the edges 81d and 82d to be aligned easily and accurately.
　布部材８３２は、補強板８１と補強板８２とに跨がるように配置され、補強板８１及び補強板８２の各々に縫合されている。布部材は、例えば、ナイロンベルト、ポリエステルベルト等によって構成され得る。図７に示されるように、布部材８３２は、矩形状に形成されている。布部材８３２は、布部材８３２の幅方向Ｄ２の中心が折り目ラインＬ２と略一致するように、折り目ラインＬ２に沿って延びている。布部材８３２の方向Ｄ１の長さは、テープ部材８３１の方向Ｄ１の長さよりも長い。すなわち、方向Ｄ１において、布部材８３２は、テープ部材８３１よりも外側まで延びている。布部材８３２は、方向Ｄ１における補強板８１，８２の端部付近まで延びている。一方、布部材８３２の幅方向Ｄ２の長さは、テープ部材８３１の幅方向Ｄ２の長さよりも短い。すなわち、幅方向Ｄ２において、テープ部材８３１は、布部材８３２よりも外側まで延びている。 The cloth member 832 is arranged so as to straddle the reinforcing plate 81 and the reinforcing plate 82, and is sewn to each of the reinforcing plate 81 and the reinforcing plate 82. The cloth member may be composed of, for example, a nylon belt, a polyester belt, or the like. As shown in FIG. 7, the cloth member 832 is formed in a rectangular shape. The cloth member 832 extends along the fold line L2 such that the center of the cloth member 832 in the width direction D2 substantially coincides with the fold line L2. The length of the cloth member 832 in the direction D1 is longer than the length of the tape member 831 in the direction D1. That is, in the direction D1, the cloth member 832 extends further outward than the tape member 831. The cloth member 832 extends to near the ends of the reinforcing plates 81 and 82 in the direction D1. On the other hand, the length of the cloth member 832 in the width direction D2 is shorter than the length of the tape member 831 in the width direction D2. That is, in the width direction D2, the tape member 831 extends to the outside of the cloth member 832.
　本実施形態では、上記のようにテープ部材８３１及び布部材８３２が配置されているため、テープ部材８３１と布部材８３２とは、互いに重なる部分を有している。また、上記部分において、テープ部材８３１は、布部材８３２と補強板８１，８２との間に配置されている。すなわち、布部材８３２は、テープ部材８３１を覆うように配置されている。 In this embodiment, since the tape member 831 and the cloth member 832 are arranged as described above, the tape member 831 and the cloth member 832 have portions that overlap with each other. Further, in the above portion, the tape member 831 is arranged between the cloth member 832 and the reinforcing plates 81 and 82. That is, the cloth member 832 is arranged to cover the tape member 831.
　図７及び図８に示されるように、布部材８３２は、折り目ラインＬ２に平行な２本の縫合ラインＳＬ１，ＳＬ２に沿って、補強板８１及びテープ部材８３１に縫合されている。縫合ラインＳＬ１は、幅方向Ｄ２において補強板８２から遠い方の布部材８３２の端部に沿っている。縫合ラインＳＬ２は、折り目ラインＬ２よりも若干補強板８１側にずれた位置において、折り目ラインＬ２に沿っている。 As shown in FIGS. 7 and 8, the cloth member 832 is sewn to the reinforcing plate 81 and the tape member 831 along two stitching lines SL1 and SL2 parallel to the fold line L2. The suture line SL1 is along the end of the cloth member 832 that is farther from the reinforcing plate 82 in the width direction D2. The suture line SL2 is along the fold line L2 at a position slightly shifted toward the reinforcing plate 81 side from the fold line L2.
　同様に、布部材８３２は、折り目ラインＬ２に平行な２本の縫合ラインＳＬ３，ＳＬ４に沿って、補強板８２及びテープ部材８３１に縫合されている。縫合ラインＳＬ３は、幅方向Ｄ２において補強板８１から遠い方の布部材８３２の端部に沿っている。縫合ラインＳＬ４は、折り目ラインＬ２よりも若干補強板８２側にずれた位置において、折り目ラインＬ２に沿っている。 Similarly, the cloth member 832 is sewn to the reinforcing plate 82 and the tape member 831 along two stitching lines SL3 and SL4 parallel to the fold line L2. The suture line SL3 is along the end of the cloth member 832 that is farther from the reinforcing plate 81 in the width direction D2. The stitching line SL4 is along the fold line L2 at a position slightly shifted toward the reinforcing plate 82 side from the fold line L2.
　上述した補強板８１，８２及び接続部材８３では、図９に示されるように、接続部材８３を構成するテープ部材８３１及び布部材８３２の両方が折り目ラインＬ２（図７参照）に沿って折れ曲がることが可能とされている。これにより、補強板８１が、外面８１ｂと外面８２ｂとが互いに接近する方向に、補強板８２に対して折れ曲がることが可能に構成されている。上記構成は、接続部材８３が補強板８１，８２の外面８１ｂ，８２ｂ側に設けられていることによって実現されている。すなわち、内面８１ａと端面８１ｃとの間の縁部８１ｅが、内面８２ａと端面８２ｃとの間の縁部８２ｅから離間可能に構成されているため、上記のように補強板８１が補強板８２に対して折れ曲がることができる。一方、接続部材８３（特にテープ部材８３１）によって、外面８１ｂと端面８１ｃとの間の縁部８１ｄが、外面８２ｂと端面８２ｃとの間の縁部８２ｄから離間しないように、縁部８２ｄに対して固定されている。これにより、縁部８１ｄと縁部８２ｄとが離間する方向（すなわち、内面８１ａと内面８２ａとが互いに接近する方向）に補強板８１が補強板８２に対して折れ曲がることが防止される。 In the reinforcing plates 81, 82 and the connecting member 83 described above, as shown in FIG. 9, both the tape member 831 and the cloth member 832 that constitute the connecting member 83 are bent along the fold line L2 (see FIG. 7). is considered possible. Thereby, the reinforcing plate 81 is configured to be able to bend relative to the reinforcing plate 82 in a direction in which the outer surface 81b and the outer surface 82b approach each other. The above configuration is realized by providing the connecting member 83 on the outer surfaces 81b and 82b of the reinforcing plates 81 and 82. That is, since the edge 81e between the inner surface 81a and the end surface 81c is configured to be able to be separated from the edge 82e between the inner surface 82a and the end surface 82c, the reinforcing plate 81 is attached to the reinforcing plate 82 as described above. It can be bent against. On the other hand, the connecting member 83 (particularly the tape member 831) prevents the edge 81d between the outer surface 81b and the end surface 81c from separating from the edge 82d between the outer surface 82b and the end surface 82c. Fixed. This prevents the reinforcing plate 81 from bending relative to the reinforcing plate 82 in the direction in which the edge 81d and the edge 82d move away from each other (that is, in the direction in which the inner surface 81a and the inner surface 82a approach each other).
　図１１に示されるように、側壁部８０は、内側生地８０１と、外側生地８０２と、内側補強生地８０３と、外側補強生地８０４と、を有している。図１１は、側壁部８０の生地構成を模式的に示す図である。内側生地８０１は、側壁部８０の最も内側に配置され、乳母車１に乗車する乳幼児に対面する表面４ａを含む生地である。外側生地８０２は、内側生地８０１よりも外側（側壁部８０の最も外側）に配置され、展開状態において左右方向（Ｙ軸方向）の外側に露出する裏面４ｂを含む生地である。内側補強生地８０３は、内側生地８０１よりも外側且つ外側生地８０２よりも内側に配置された生地である。外側補強生地８０４は、外側生地８０２よりも内側且つ内側補強生地８０３よりも外側に配置された生地である。内側生地８０１は、乳幼児の肌に触れる部分であるため、例えば、ポリエステルニット生地等の比較的柔らかい生地によって構成され得る。外側生地８０２、内側補強生地８０３、及び外側補強生地８０４は、例えば、ポリエステル織生地等によって構成され得る。 As shown in FIG. 11, the side wall portion 80 includes an inner fabric 801, an outer fabric 802, an inner reinforcing fabric 803, and an outer reinforcing fabric 804. FIG. 11 is a diagram schematically showing the fabric structure of the side wall portion 80. The inner fabric 801 is a fabric that is disposed at the innermost side of the side wall portion 80 and includes a surface 4a that faces an infant riding in the baby carriage 1. The outer fabric 802 is a fabric that is disposed outside the inner fabric 801 (the outermost side of the side wall portion 80) and includes a back surface 4b that is exposed to the outside in the left-right direction (Y-axis direction) in the unfolded state. The inner reinforcing fabric 803 is a fabric disposed outside the inner fabric 801 and inside the outer fabric 802. The outer reinforcing fabric 804 is a fabric disposed inside the outer fabric 802 and outside the inner reinforcing fabric 803. The inner fabric 801 is a part that comes into contact with the baby's skin, so it may be made of relatively soft fabric such as polyester knit fabric, for example. The outer fabric 802, the inner reinforcing fabric 803, and the outer reinforcing fabric 804 may be made of, for example, polyester woven fabric.
　補強板８１，８２及び接続部材８３は、内側補強生地８０３と外側補強生地８０４との間に収容されている。また、補強板８１，８２は、内側補強生地８０３及び外側補強生地８０４の少なくとも一方に固定されている。本実施形態では、図１１に示されるように、補強板８１，８２は、上述した縫合ラインＳＬ１～ＳＬ４に沿って、接続部材８３と共に外側補強生地８０４に縫合されている。また、補強板８１，８２の外縁部は、当該外縁部に沿った縫合ラインＳＬ５に沿って、外側補強生地８０４に縫合されている。また、内側生地８０１、外側生地８０２、内側補強生地８０３、及び外側補強生地８０４は、それぞれの縁部に沿った縫合ラインＳＬ６に沿って、互いに縫合されている。 The reinforcing plates 81 and 82 and the connecting member 83 are housed between the inner reinforcing fabric 803 and the outer reinforcing fabric 804. Furthermore, the reinforcing plates 81 and 82 are fixed to at least one of the inner reinforcing fabric 803 and the outer reinforcing fabric 804. In this embodiment, as shown in FIG. 11, the reinforcing plates 81 and 82 are sewn together with the connecting member 83 to the outer reinforcing fabric 804 along the above-mentioned stitching lines SL1 to SL4. Further, the outer edges of the reinforcing plates 81 and 82 are sewn to the outer reinforcing fabric 804 along a stitching line SL5 along the outer edges. Moreover, the inner fabric 801, the outer fabric 802, the inner reinforced fabric 803, and the outer reinforced fabric 804 are sewn together along the stitching line SL6 along the respective edges.
　以上説明したシート３では、各側壁部８０は、接続部材８３を介して互いに接続された補強板８１，８２を有する。接続部材８３は、少なくとも補強板８１，８２の境界に沿って折り曲げ可能とされている。これにより、図９に示したように、外面８１ｂと外面８２ｂとが互いに近づく方向に、補強板８１を補強板８２に対して折り曲げること（すなわち、側壁部８０を左右方向（Ｙ軸方向）の内側に突出するように折り曲げること）ができる。一方、接続部材８３が外面８１ｂ，８２ｂに固定されているため、端面８１ｃのうち外面８１ｂに接続される縁部８１ｄ（図９参照）と端面８２ｃのうち外面８２ｂに接続される縁部８２ｄ（図９参照）とが接触（或いは近接）した状態が維持される。すなわち、内面８１ａと内面８２ａとが互いに近づく方向に補強板８１が補強板８２に対して折れ曲がること（すなわち、側壁部８０が左右方向（Ｙ軸方向）の外側に突出するように折れ曲がること）が防止される。従って、乳母車１の折り畳み動作時において、側壁部８０が左右方向（Ｙ軸方向）の外側に拡がるように折り畳まれることが防止される。さらに、接続部材８３は、外面８１ｂと外面８２ｂとがなす角度が減少する方向に補強板８１が補強板８２に対して折れ曲がるように補強板８１及び補強板８２を付勢しない態様で、補強板８１と補強板８２とを接続している。すなわち、展開状態において、接続部材８３は、側壁部８０が左右方向（Ｙ軸方向）の内側に突出するように折れ曲がることを助長しないように構成されている。これにより、展開状態において、補強板８１と補強板８２とが平行な状態（すなわち、端面８１ｃと端面８２ｃとが接触し、外面８１ｂ及び外面８２ｂが面一な状態）が適切に維持され、乳幼児の乗車スペースが側壁部８０によって圧迫されることが防止される。加えて、側壁部８０の左右方向（Ｙ軸方向）の外側と乳母車本体２との間のスペースが大きくなり、当該スペースに乳幼児の身体の一部や玩具等が挟まれ易くなるといった問題の発生を回避することもできる。 In the seat 3 described above, each side wall portion 80 has reinforcing plates 81 and 82 that are connected to each other via a connecting member 83. The connecting member 83 is bendable at least along the boundary between the reinforcing plates 81 and 82. As a result, as shown in FIG. 9, the reinforcing plate 81 is bent relative to the reinforcing plate 82 in the direction in which the outer surface 81b and the outer surface 82b approach each other (that is, the side wall portion 80 is bent in the left-right direction (Y-axis direction)). (can be bent so that it protrudes inward). On the other hand, since the connecting member 83 is fixed to the outer surfaces 81b and 82b, an edge 81d (see FIG. 9) of the end surface 81c that is connected to the outer surface 81b and an edge 82d (see FIG. 9) of the end surface 82c that is connected to the outer surface 82b (see FIG. 9) are maintained in contact with (or in close proximity to). That is, the reinforcing plate 81 is not bent relative to the reinforcing plate 82 in the direction in which the inner surface 81a and the inner surface 82a approach each other (that is, the side wall portion 80 is not bent so as to protrude outward in the left-right direction (Y-axis direction)). Prevented. Therefore, during the folding operation of the baby carriage 1, the side wall portion 80 is prevented from being folded so as to expand outward in the left-right direction (Y-axis direction). Further, the connecting member 83 is configured such that the reinforcing plate 81 and the reinforcing plate 82 are not biased so that the reinforcing plate 81 is bent relative to the reinforcing plate 82 in a direction in which the angle formed between the outer surface 81b and the outer surface 82b decreases. 81 and a reinforcing plate 82 are connected. That is, in the unfolded state, the connecting member 83 is configured not to encourage the side wall portion 80 to bend so as to protrude inward in the left-right direction (Y-axis direction). As a result, in the unfolded state, the reinforcing plate 81 and the reinforcing plate 82 are properly maintained in a parallel state (that is, the end surface 81c and the end surface 82c are in contact and the outer surface 81b and the outer surface 82b are flush with each other), and the infant This prevents the passenger space from being compressed by the side wall portion 80. In addition, the space between the outer side of the side wall portion 80 in the left-right direction (Y-axis direction) and the baby carriage main body 2 becomes larger, causing problems such as parts of the baby's body, toys, etc., becoming more likely to get caught in the space. can also be avoided.
　接続部材８３は、外面８１ｂと外面８２ｂとに跨がるように配置され、外面８１ｂ，８２ｂに貼付されたテープ部材８３１を有している。上記構成によれば、テープ部材８３１によって補強板８１及び補強板８２を接続することにより、展開状態において、外面８１ｂ，８２ｂが面一となる状態をより確実に維持することができる。これにより、展開状態において端面８１ｃに対して端面８２ｃがずれてしまい、補強板８１と補強板８２とが互いに重なってしまうこと（その結果、折り畳み動作時において補強板８１が補強板８２に対して適切に折れ曲がることが阻害されること）を防止することができる。 The connecting member 83 is arranged so as to straddle the outer surface 81b and the outer surface 82b, and has a tape member 831 affixed to the outer surfaces 81b and 82b. According to the above configuration, by connecting the reinforcing plate 81 and the reinforcing plate 82 with the tape member 831, it is possible to more reliably maintain a state in which the outer surfaces 81b and 82b are flush with each other in the unfolded state. As a result, the end face 82c is displaced from the end face 81c in the unfolded state, and the reinforcing plate 81 and the reinforcing plate 82 overlap each other (as a result, the reinforcing plate 81 is displaced from the reinforcing plate 82 during the folding operation). This can prevent the material from being properly bent.
　接続部材８３は、外面８１ｂと外面８２ｂとに跨がるように配置され、補強板８１及び補強板８２の各々に縫合された布部材８３２を有している。例えば、接続部材８３としてテープ部材８３１を用いた場合には、経時的なテープ部材８３１の粘着力の低下に起因して、テープ部材８３１が外面８１ｂ又は外面８２ｂから剥がれてしまうおそれがある。一方、接続部材８３として布部材８３２を用いる上記構成によれば、外面８１ｂ，８２ｂにあてがった布部材８３２を補強板８１，８２に縫合することにより、補強板８１，８２から接続部材８３が外れてしまうことを防止し、補強板８１と補強板８２とをより安定的に接続することができる。 The connecting member 83 is arranged so as to straddle the outer surface 81b and the outer surface 82b, and has a cloth member 832 sewn to each of the reinforcing plates 81 and 82. For example, when the tape member 831 is used as the connecting member 83, there is a risk that the tape member 831 may peel off from the outer surface 81b or the outer surface 82b due to a decrease in the adhesive force of the tape member 831 over time. On the other hand, according to the above configuration in which the cloth member 832 is used as the connecting member 83, the connecting member 83 is detached from the reinforcing plates 81, 82 by sewing the cloth member 832 applied to the outer surfaces 81b, 82b to the reinforcing plates 81, 82. It is possible to prevent the reinforcing plate 81 and the reinforcing plate 82 from being damaged, and to connect the reinforcing plate 81 and the reinforcing plate 82 more stably.
　接続部材８３は、上述したテープ部材８３１及び布部材８３２の両方を有している。上記構成によれば、上述したテープ部材８３１及び布部材８３２の両方の効果を得ることができる。すなわち、布部材８３２を用いることによって、補強板８１と補強板８２とをより安定的に接続することができると共に、テープ部材８３１を用いることによって、端面８１ｃに対して端面８２ｃがずれてしまうことを防止することができる。 The connecting member 83 includes both the tape member 831 and cloth member 832 described above. According to the above configuration, the effects of both the tape member 831 and cloth member 832 described above can be obtained. That is, by using the cloth member 832, the reinforcing plate 81 and the reinforcing plate 82 can be connected more stably, and by using the tape member 831, the end face 82c can be prevented from shifting from the end face 81c. can be prevented.
　テープ部材８３１と布部材８３２とは、互いに重なる部分を有し、上記部分において、テープ部材８３１は、布部材８３２と補強板８１，８２との間に配置されている。上記構成によれば、テープ部材８３１と布部材８３２とが互いに重なる部分において、布部材８３２によってテープ部材８３１を適切に保護することができる。すなわち、上記部分において、テープ部材８３１の表面が外部に露出することが防止される。その結果、乳母車１の使用時等に発生する外部からの衝撃等に起因するテープ部材８３１の損傷を抑制し、外面８１ｂ又は外面８２ｂからテープ部材８３１が剥がれてしまうことを抑制することができる。 The tape member 831 and the cloth member 832 have a mutually overlapping part, and in the said part, the tape member 831 is arranged between the cloth member 832 and the reinforcing plates 81 and 82. According to the above configuration, the tape member 831 can be appropriately protected by the cloth member 832 in the portion where the tape member 831 and the cloth member 832 overlap with each other. That is, in the above portion, the surface of the tape member 831 is prevented from being exposed to the outside. As a result, it is possible to suppress damage to the tape member 831 caused by external shocks generated when the baby carriage 1 is used, and to prevent the tape member 831 from peeling off from the outer surface 81b or the outer surface 82b.
　テープ部材８３１は、上記部分において、布部材８３２と共に補強板８１及び補強板８２の各々に縫合されている。上記構成によれば、テープ部材８３１が布部材８３２と共に補強板８１，８２に対して強固に固定（縫合）されるため、外面８１ｂ又は外面８２ｂからテープ部材８３１が剥がれてしまうことをより効果的に抑制することができる。 The tape member 831 is sewn to each of the reinforcing plates 81 and 82 together with the cloth member 832 in the above portion. According to the above configuration, since the tape member 831 is firmly fixed (stitched) to the reinforcing plates 81 and 82 together with the cloth member 832, peeling of the tape member 831 from the outer surface 81b or the outer surface 82b can be more effectively prevented. can be suppressed to
　補強板８１と補強板８２との境界（折り目ラインＬ２）に沿った布部材８３２の長さ（すなわち、方向Ｄ１における長さ）は、方向Ｄ１に沿ったテープ部材８３１の長さよりも長い。粘着材料を有するテープ部材８３１を布部材８３２及び補強板８１，８２と共に縫合する場合、縫合する際に用いられるミシン針等に粘着材料が付着し、ミシンの動作異常等を引き起こすおそれがある。上記のように、布部材８３２をテープ部材８３１よりも長くすることにより、布部材８３２が補強板８１，８２に縫合される全体領域に対して、テープ部材８３１が布部材８３２と共に縫合される領域の割合を小さくすることができる。その結果、上述したようなテープ部材８３１の粘着材料に起因するトラブルの発生を抑制できる。 The length of the cloth member 832 along the boundary (fold line L2) between the reinforcing plates 81 and 82 (that is, the length in the direction D1) is longer than the length of the tape member 831 along the direction D1. When sewing the tape member 831 containing an adhesive material together with the cloth member 832 and the reinforcing plates 81 and 82, there is a risk that the adhesive material may adhere to a sewing machine needle or the like used for sewing, causing abnormal operation of the sewing machine. As described above, by making the cloth member 832 longer than the tape member 831, the area where the tape member 831 is sewn together with the cloth member 832 is larger than the entire area where the cloth member 832 is sewn to the reinforcing plates 81 and 82. It is possible to reduce the proportion of As a result, the occurrence of troubles caused by the adhesive material of the tape member 831 as described above can be suppressed.
　側壁部８０は、内側生地８０１と、外側生地８０２と、内側補強生地８０３と、外側補強生地８０４と、を有し、補強板８１，８２及び接続部材８３は、内側補強生地８０３と外側補強生地８０４との間に収容されており、補強板８１，８２は、内側補強生地８０３及び外側補強生地８０４の少なくとも一方（本実施形態では、外側補強生地８０４）に固定されている。上記構成では、補強板８１，８２が内側補強生地８０３と外側補強生地８０４とで挟み込まれた状態で、さらにその外側が内側生地８０１と外側生地８０２とで覆われる。このように補強板８１，８２を二重の生地で保護することにより、側壁部８０に対して外部からの衝撃が加わった際に、側壁部８０のうち外部に露出した生地（内側生地８０１及び外側生地８０２）に破れ等が生じた場合でも、補強用生地（内側補強生地８０３及び外側補強生地８０４）によって補強板８１，８２が外部に露出することが防止される。その結果、補強板８１，８２が外部に露出することによる見栄えの悪化、外部に露出した補強板８１，８２と乳母車本体２との接触等による補強板８１，８２の破損等を防止することができる。 The side wall portion 80 has an inner fabric 801, an outer fabric 802, an inner reinforcing fabric 803, and an outer reinforcing fabric 804, and the reinforcing plates 81, 82 and the connecting member 83 have an inner reinforcing fabric 803 and an outer reinforcing fabric 804, and the reinforcing plates 81, 82 are fixed to at least one of the inner reinforcing fabric 803 and the outer reinforcing fabric 804 (in this embodiment, the outer reinforcing fabric 804). In the above configuration, the reinforcing plates 81 and 82 are sandwiched between the inner reinforcing fabric 803 and the outer reinforcing fabric 804, and the outer sides thereof are further covered with the inner fabric 801 and the outer fabric 802. By protecting the reinforcing plates 81 and 82 with double fabric in this way, when an external impact is applied to the side wall 80, the fabric exposed to the outside of the side wall 80 (inner fabric 801 and Even if a tear or the like occurs in the outer fabric 802), the reinforcing plates 81 and 82 are prevented from being exposed to the outside by the reinforcing fabrics (inner reinforcing fabric 803 and outer reinforcing fabric 804). As a result, it is possible to prevent deterioration in appearance due to the reinforcing plates 81, 82 being exposed to the outside, and damage to the reinforcing plates 81, 82 due to contact between the reinforcing plates 81, 82 exposed to the outside and the baby carriage main body 2, etc. can.
　以上説明した乳母車１は、上述したシート３と、シート３を支持し、展開状態から折り畳み状態へと変形可能な乳母車本体２と、を備える。乳母車１によれば、上述したシート３を備えることにより、乳母車１の展開状態における乳幼児の乗車スペースが圧迫されることを防止しつつ、乳母車１の折り畳み動作時において側壁部８０が左右方向（Ｙ軸方向）の外側に拡がるように折り畳まれることを防止することができる。 The baby carriage 1 described above includes the seat 3 described above, and the baby carriage main body 2 that supports the seat 3 and is deformable from an unfolded state to a folded state. According to the baby carriage 1, by including the seat 3 described above, the riding space for the infant is prevented from being compressed when the baby carriage 1 is in the unfolded state, and the side wall portion 80 is moved in the left-right direction (Y) when the baby carriage 1 is folded. This can prevent it from being folded so as to expand outward in the axial direction.
