Description

本発明は、幼児搬送装置、特に、複数の使用形態を有する幼児搬送装置に関する。
《関連する出願への相互参照》
本出願は、２０１０年４月１日付で出願した中国特許出願第２０１０１０１３８７５１．１号に基づく優先権を主張するものである。 The present invention relates to an infant carrier, and more particularly to an infant carrier having a plurality of usage forms.
《Cross-reference to related applications》
This application claims priority based on Chinese Patent Application No. 201010138751.1 filed on April 1, 2010.

ベビーカーは、一般に車輪を備えた支持フレームと、座席組立体と、ハンドルとからなる。子供を座席に座らせた後、親は該ハンドルを使用してベビーカーを押して移動させることが出来る。従来のベビーカーでは、通常、該座席組立体がベビーカーの移動方向に対して前方を向いている。ベビーカーに座っている子供は親と対面していないので、子供と親との対話ができない。   A stroller generally includes a support frame having wheels, a seat assembly, and a handle. After the child is seated, the parent can use the handle to push and move the stroller. In a conventional stroller, the seat assembly usually faces forward with respect to the moving direction of the stroller. Since the child sitting in the stroller is not facing the parent, the child cannot interact with the parent.

上記欠点を解消すため、前後に調整可能な背もたれを備えたベビーカーが現在提案している。これにより、子供を前向きに着座させたり、或いは親と対面する後向きに着座させることが出来る。このような従来のベビーカーは複数の着座形態が可能であるが、これらのベビーカーの背もたれ調整機構は構造及び操作が複雑で製造コストを増加させている。   In order to eliminate the above drawbacks, a baby stroller with a backrest that can be adjusted back and forth is currently proposed. Accordingly, the child can be seated forward or seated backward facing the parent. Although such a conventional baby stroller can have a plurality of seating configurations, the backrest adjustment mechanism of these baby strollers is complicated in structure and operation and increases the manufacturing cost.

従って、現在、複数の使用形態が可能であって、少なくとも上記の問題に対処することが出来る幼児搬送装置が必要とされている。   Therefore, there is currently a need for an infant carrier that can be used in multiple ways and that can address at least the above problems.

本発明は複数の使用形態を有し、背もたれの向きを変えるよう容易に且つ便利に操作できる幼児搬送装置を開示する。   The present invention discloses an infant carrying apparatus that has a plurality of usage forms and can be easily and conveniently operated to change the direction of the backrest.

１つの実施形態では、本幼児搬送装置は支持フレームと、着座部材を有する座席組立体と、ラッチ部を有する管部を備え、該座席組立体に対して回転するよう操作可能な背もたれ組立体と、該ラッチ部と係合し該背もたれ組立体を所望の姿勢に保持するよう適合した背もたれ保持基部とを備え、該背もたれ組立体は、水平な折畳み使用形態となるよう該着座部材にほぼ平行に横たわる姿勢に調整可能である。   In one embodiment, the infant carrier apparatus includes a support frame, a seat assembly having a seating member, and a backrest assembly operable to rotate relative to the seat assembly, including a tube portion having a latch portion. A backrest holding base adapted to engage the latch portion and hold the backrest assembly in a desired position, the backrest assembly being substantially parallel to the seating member for horizontal folding use. Adjustable to lying posture.

本発明は複数の使用形態を有し、背もたれの向きを変えるよう容易に且つ便利に操作できる幼児搬送装置１００を開示する。
図１に示すように、幼児搬送装置１００は典型的には、支持フレーム２と、背もたれ組立体４と、座席組立体６と、一対の背もたれ保持基部８とを備えていて、本例では幼児搬送装置１００がベビーカー装置である場合について説明する。
支持フレーム２は前脚２２Ａと、後脚２２Ｂと、側肘かけ２４と、複数の車輪２６とを備えている。前脚２２Ａと後脚２２Ｂは側肘かけ２４に回動可能に結合された上端と、車輪２６に装着された下端とを有している。 The present invention discloses an infant carrier apparatus 100 that has a plurality of usage forms and can be easily and conveniently operated to change the direction of the backrest.
As shown in FIG. 1, the infant carrier 100 typically includes a support frame 2, a backrest assembly 4, a seat assembly 6, and a pair of backrest holding bases 8. A case where the transport device 100 is a stroller device will be described.
The support frame 2 includes a front leg 22A, a rear leg 22B, a side armrest 24, and a plurality of wheels 26. The front leg 22 </ b> A and the rear leg 22 </ b> B have an upper end rotatably coupled to the side armrest 24 and a lower end attached to the wheel 26.

背もたれ組立体４は左側と右側の管部４２と、左右の側レール４４と、左右の管部４２及び側レール４４を接続する横結合リンク４６とを備える。左右の管部４２と側レール４４は座席組立体６の左右の縁に近接して配置される。各管部４２と、同じ側の関連する側レール４４は互いに離間され、背もたれ組立体４の長さ方向軸に沿ってほぼ平行に延在している。後述するように、管部４２及び側レール４４は、結合リンク４６と背もたれ組立体４の調整を可能にする座席組立体６に近接した回動シャフトとにそれぞれ接続された第１端部と反対側の第２端部とを有している。   The backrest assembly 4 includes left and right tube portions 42, left and right side rails 44, and lateral coupling links 46 that connect the left and right tube portions 42 and the side rails 44. The left and right pipe portions 42 and the side rails 44 are disposed in proximity to the left and right edges of the seat assembly 6. Each tube 42 and the associated side rail 44 on the same side are spaced apart from each other and extend substantially parallel along the longitudinal axis of the backrest assembly 4. As will be described below, the tube portion 42 and the side rail 44 are opposite to the first end respectively connected to the coupling link 46 and the pivot shaft proximate to the seat assembly 6 that allows adjustment of the backrest assembly 4. And a second end portion on the side.

結合リンク４６は、座席組立体６の幅方向（即ち、左側から右側へ）に沿って横切って延在する中央部又は横断部４６Ａと、中央部４６Ａの左端と右端にそれぞれ接合する曲折した側部４６Ｂとを備える概ねＵ字形を有している。横断部４６Ａと側部４６Ｂとを備える結合リンク４６は一体に形成されている。   The coupling link 46 includes a central portion or a transverse portion 46A extending across the width direction of the seat assembly 6 (that is, from the left side to the right side), and a bent side joined to the left end and the right end of the central portion 46A, respectively. It has a generally U shape with a portion 46B. The coupling link 46 including the crossing part 46A and the side part 46B is integrally formed.

座席組立体６の同じ側（即ち、左側と右側）の管部４２と側レール４４はそれぞれ、結合リンク４６の対応する側部４６Ｂに回動点ＡとＢにおいて接続された第１端部４２１と４４２（即ち、座席組立体６から離れた端部）を有する。回動点Ａは側部４６Ｂの末端に回動点Ｂより近い。この接続により、背もたれ組立体４の傾斜を調整する時、管部４２と側レール４４は同期して動くことが出来る。２つの管部４２と、２つの側レール４４と、結合リンク４６とは、幼児搬送装置１００に着座した子供を支える背もたれ枠を形成する。側レール４４は子供に側もたれ支持を提供できる。   The tube portion 42 and the side rail 44 on the same side (ie, the left side and the right side) of the seat assembly 6 are respectively connected to the corresponding side portion 46B of the coupling link 46 at the first ends 421 at the pivot points A and B. And 442 (ie, the end away from the seat assembly 6). The pivot point A is closer to the end of the side portion 46B than the pivot point B. By this connection, when adjusting the inclination of the backrest assembly 4, the pipe part 42 and the side rail 44 can move synchronously. The two pipe portions 42, the two side rails 44, and the coupling link 46 form a backrest frame that supports a child seated on the infant transport apparatus 100. The side rails 44 can provide side support for the child.

図１を再び参照すると、座席組立体６は着座部材である座板６２を備えている。座板６２は、前部及び後部着座面６Ａ、６Ｂをそれぞれ形成する前部と後部を有している。座板６２の前部は、前脚２２Ａに固定接続され横方向に突出したスタッド６２２を備えた左側縁と右側縁を有している。また、凸部６４が座板６２の上面上、左右両側に形成されている。各側レール４４は関連する凸部６４に回動シャフト６４２（例えば、ピン又はリベット）を介して回動可能に接続された下又は第２端部４４４を有する。   Referring back to FIG. 1, the seat assembly 6 includes a seat plate 62 that is a seating member. The seat plate 62 has a front portion and a rear portion that form front and rear seating surfaces 6A and 6B, respectively. The front portion of the seat plate 62 has a left side edge and a right side edge provided with studs 622 that are fixedly connected to the front legs 22A and project laterally. In addition, convex portions 64 are formed on the upper surface of the seat plate 62 on both the left and right sides. Each side rail 44 has a lower or second end 444 that is pivotally connected to an associated projection 64 via a pivot shaft 642 (eg, a pin or rivet).

また、Ｕ字形のハンドル要素２８が座板６２の上方、跨った姿勢で装着されている。特に、ハンドル要素２８は後脚２２Ｂに接続要素２８２を介してそれぞれ結合された２つの側部を有している。これによりユーザは幼児搬送装置１００をハンドル要素２８により操作できる。   In addition, a U-shaped handle element 28 is mounted in a posture straddling the seat plate 62. In particular, the handle element 28 has two sides each coupled to the rear leg 22B via a connecting element 282. As a result, the user can operate the infant conveying apparatus 100 with the handle element 28.

図１に示すように、２つの細長い開口６６が座板６２の左側と右側に凸部６４の内側に近接して形成されている。背もたれ保持基部８は開口６６を貫通し、座板６２の内側壁に横方向両側において固定されている。管部４２は背もたれ保持基部８に可動に接続された第２端部を有し、ラッチ部４２２を備える。各ラッチ部４２２は関連する背もたれ保持基部８と解放可能に係合し、背もたれ組立体４（管部４２と側レール４４を含む）を、所望の姿勢に調整した後、適切な位置にロックするよう操作可能である。   As shown in FIG. 1, two elongated openings 66 are formed on the left side and the right side of the seat plate 62 adjacent to the inside of the convex portion 64. The backrest holding base 8 passes through the opening 66 and is fixed to the inner wall of the seat plate 62 on both sides in the lateral direction. The tube portion 42 has a second end portion movably connected to the backrest holding base portion 8 and includes a latch portion 422. Each latch portion 422 releasably engages with the associated backrest holding base 8 and locks the backrest assembly 4 (including the tube portion 42 and the side rail 44) in place after being adjusted to the desired position. It is possible to operate.

図２と図３は背もたれ保持基部８と管部４２との組立体を例示する斜視図と部分断面図である。背もたれ保持基部８は概ね半円形のハウジング８２等の単一体内に形成された中空要素を備えている。ハウジング８２は上側が開放され複数のロック溝８２２が設けられた内部底面を有する内部空洞８４を備えている。管部４２の第２端部（即ち、第１端部４２１と反対側）はハウジング８２の上部開口を通って内部空洞８４内に入り、ハウジング８２と管部４２の回転軸を規定する回動シャフト８２４（例えば、ピン又はリベット）を介して接続される。複数のロック溝８２２は回動シャフト８２４に関して異なる半径方向に配置されている。１つの実施形態では、図３に示すように、管部４２と側レール４４との回転運動が可能なように回動シャフト８２４は回動シャフト６４２の真下で平行に配置されている。また、回動シャフト８２４は座板６２の同じ側に位置するハンドル要素２８の近接側部と回動可能接続するよう延在している（図１に示す）。従って、管部４２とハンドル要素２８は同じ回動軸の周りを回転可能となる。   2 and 3 are a perspective view and a partial cross-sectional view illustrating an assembly of the backrest holding base portion 8 and the tube portion 42, respectively. The backrest holding base 8 comprises a hollow element formed within a single body, such as a generally semicircular housing 82. The housing 82 includes an internal cavity 84 having an internal bottom surface that is open on the upper side and provided with a plurality of lock grooves 822. A second end of the tube portion 42 (ie, opposite to the first end portion 421) enters the internal cavity 84 through the upper opening of the housing 82, and rotates to define the rotation axis of the housing 82 and the tube portion 42. Connected via a shaft 824 (eg, pin or rivet). The plurality of lock grooves 822 are arranged in different radial directions with respect to the rotation shaft 824. In one embodiment, as shown in FIG. 3, the rotation shaft 824 is arranged in parallel under the rotation shaft 642 so that the tube portion 42 and the side rail 44 can rotate. Further, the rotation shaft 824 extends so as to be able to rotate and connect to the adjacent side portion of the handle element 28 located on the same side of the seat plate 62 (shown in FIG. 1). Accordingly, the tube portion 42 and the handle element 28 can rotate around the same rotation axis.

図３に示すように、管部４２は、管部４２の回転軸を規定する回動シャフト８２４が貫通する細長いスロット４２４を備えている。管部４２の内側にバネ４２６が装着され、バネ４２６は回動シャフト８２４に固定された第１端と管部４２内に形成された突起に固定された第２端を有する。バネ４２６は管部４２をロック溝８２２の１つとロック係合する位置へ付勢するよう動作可能である。回動シャフト８２４の細長いスロット４２４を貫通するスライド接続によって、管部４２は回動シャフト８２４の周りの回転に加えて、回動シャフト８２４と背もたれ保持基部８とに対して長さ方向軸Ｘに沿って移動可能である。   As shown in FIG. 3, the tube portion 42 includes an elongated slot 424 through which a rotation shaft 824 that defines the rotation axis of the tube portion 42 passes. A spring 426 is attached to the inside of the tube portion 42, and the spring 426 has a first end fixed to the rotating shaft 824 and a second end fixed to a protrusion formed in the tube portion 42. The spring 426 is operable to bias the tube portion 42 into a position for locking engagement with one of the locking grooves 822. By sliding connection through the elongated slot 424 of the pivot shaft 824, the tube portion 42 is rotated about the longitudinal axis X relative to the pivot shaft 824 and the backrest holding base 8 in addition to rotation around the pivot shaft 824. It can move along.

図３において、管部４２は背もたれ保持基部８とロック係合した状態で示されている。より具体的には、ラッチ部４２２はロック溝８２２の１つと係合し、管部４２と側レール４４の回転を阻止するので、背もたれ組立体４は所望の傾斜角で適切な位置にロックされる。   In FIG. 3, the tube part 42 is shown in a locked engagement with the backrest holding base 8. More specifically, the latch portion 422 engages with one of the locking grooves 822 and prevents the tube portion 42 and the side rail 44 from rotating, so that the backrest assembly 4 is locked in place at the desired tilt angle. The

図４を参照すると、ユーザが背もたれ組立体４を調整する時、管部４２をＦ方向に引っ張りラッチ部４２２をロック溝８２２から解放する。その結果、バネ４２６は圧縮される。この操作は側レール４４と結合リンク４６とに対する管部４２の移動に加えて、結合リンク４６の僅かな変位を引き起こす。ラッチ部４２２の解放後、背もたれ組立体４をその姿勢を調整するために回転させることが出来る。結合リンク４６を介する相互接続によって、管部４２と側レール４４は、背もたれ組立体４を調整する時、同期して動く。即ち、側レール４４が回動シャフト６４２の周りを回転する時、同期して管部４２は回動シャフト８２４の周りを回転する。背もたれ組立体４を所望の姿勢に調整した後、バネ４２６により加えられたバネ力は、管部４２のラッチ部４２２を対応するロック溝８２２と係合するよう付勢するので、背もたれ組立体４は新しい傾斜角に確実に保持される。   Referring to FIG. 4, when the user adjusts the backrest assembly 4, the tube portion 42 is pulled in the F direction to release the latch portion 422 from the lock groove 822. As a result, the spring 426 is compressed. This operation causes a slight displacement of the coupling link 46 in addition to the movement of the tube portion 42 relative to the side rail 44 and the coupling link 46. After the release of the latch 422, the backrest assembly 4 can be rotated to adjust its posture. Due to the interconnection through the coupling link 46, the tube part 42 and the side rail 44 move synchronously when adjusting the backrest assembly 4. That is, when the side rail 44 rotates around the rotation shaft 642, the tube portion 42 rotates around the rotation shaft 824 in synchronization. After adjusting the backrest assembly 4 to a desired posture, the spring force applied by the spring 426 urges the latch portion 422 of the tube portion 42 to engage with the corresponding lock groove 822, and thus the backrest assembly 4. Is securely held at the new tilt angle.

図４に破線で示すように、管部４２と側レール４４とを備える背もたれ組立体４を座席組立体に近接し概ね水平な姿勢に畳むことも出来る。この姿勢では、ラッチ部４２２は完全に内部空洞８４の外に横たわる。また、バネ４２６により加えられたバネ力は、ラッチ部４２２をロック溝８２２から離れた異なる別のロック位置（水平な矢印で示す）に係合するよう付勢する。１つの実施形態では、バネ４２６により加えられたバネ力は、背もたれ組立体４のＤ１方向の回転を阻止する当接面８２８に接触し係合するようラッチ部４２２を付勢することが出来る。また、管部４２のラッチ部４２２から隔たった部分は、背もたれ組立体４のＤ１方向と反対のＤ２方向の回転を阻止する別の当接面８２９に接触している。このようにして、背もたれ組立体４は座板６２にほぼ平行な水平な折畳み姿勢に確実に保持される。   As shown by a broken line in FIG. 4, the backrest assembly 4 including the pipe portion 42 and the side rail 44 can be folded close to the seat assembly in a substantially horizontal posture. In this position, the latch portion 422 lies completely outside the internal cavity 84. Further, the spring force applied by the spring 426 urges the latch portion 422 to engage with another different lock position (indicated by a horizontal arrow) away from the lock groove 822. In one embodiment, the spring force applied by the spring 426 can bias the latch portion 422 to contact and engage the abutment surface 828 that prevents rotation of the backrest assembly 4 in the D1 direction. Further, the portion of the pipe portion 42 that is separated from the latch portion 422 is in contact with another contact surface 829 that prevents the backrest assembly 4 from rotating in the direction D2 opposite to the direction D1. In this way, the backrest assembly 4 is securely held in a horizontal folded posture substantially parallel to the seat plate 62.

１つの実施形態では、当接面８２８はハウジング８２又は座板６２の上面により形成され、反対側の当接面８２９はハウジング８２又は座板６２の後端面により形成されている。当接面８２８、８２９を形成する多数の異なるやり方が可能であることは理解されるであろう。例えば、これらの当接面を形成するよう別の板要素をハウジング８２、座板６２、又は支持フレーム２の他の領域のいずれかに取り付けてもよい。   In one embodiment, the contact surface 828 is formed by the upper surface of the housing 82 or the seat plate 62, and the opposite contact surface 829 is formed by the rear end surface of the housing 82 or the seat plate 62. It will be appreciated that many different ways of forming the abutment surfaces 828, 829 are possible. For example, another plate element may be attached to either the housing 82, the seat plate 62, or any other region of the support frame 2 to form these abutment surfaces.

背もたれ組立体４を概ね水平な姿勢から傾斜姿勢へ調整する時、管部４２を引っ張りラッチ部４２２を当接面８２８から解放する。次に、背もたれ組立体４を所望の傾斜角へ回転させると、ラッチ部４２２はハウジング８２の内部空洞８４内を移動する。   When the backrest assembly 4 is adjusted from the substantially horizontal posture to the inclined posture, the tube portion 42 is pulled to release the latch portion 422 from the contact surface 828. Next, when the backrest assembly 4 is rotated to a desired tilt angle, the latch portion 422 moves within the internal cavity 84 of the housing 82.

図５〜図８は幼児搬送装置１００の様々な使用形態を例示した概略図である。図５には、前向き着座形態にある幼児搬送装置１００が示されている。背もたれ組立体４は後方へ傾斜し、子供を座席組立体６上に前向きに着座させることが出来る。   5 to 8 are schematic views illustrating various usage forms of the infant carrier apparatus 100. FIG. 5 shows the infant carrier 100 in a forward-facing seating configuration. The backrest assembly 4 can be tilted rearward to seat the child forward on the seat assembly 6.

図６は、背もたれ組立体４が後方への水平な折畳み使用形態にある幼児搬送装置１００を例示する概略図である。背もたれ組立体４は後方へほぼ水平な姿勢に折り畳まれ、座席組立体６の後部着座面６Ｂに近接している。ラッチ部４２２はハウジング８２の内部空洞８４の外に位置し、当接面８２８に接触し係合して（図４に示すように）背もたれ組立体４の前方回転を防ぐ。一方、管部４２に当接する当接面８２９は背もたれ組立体４の後方回転を阻止する。この使用形態では、子供は前部着座面６Ａと背もたれ組立体４との上にほぼ水平な眠る姿勢に横たわることが出来、足は前方に位置し、頭は後方に位置する。   FIG. 6 is a schematic view illustrating the infant carrier apparatus 100 in which the backrest assembly 4 is in a horizontal folding use configuration in the rearward direction. The back assembly 4 is folded rearward in a substantially horizontal posture and is close to the rear seating surface 6B of the seat assembly 6. The latch portion 422 is located outside the internal cavity 84 of the housing 82 and contacts and engages the abutment surface 828 (as shown in FIG. 4) to prevent forward rotation of the backrest assembly 4. On the other hand, the abutment surface 829 that abuts the tube portion 42 prevents the backrest assembly 4 from rotating backward. In this mode of use, the child can lie on a substantially horizontal sleeping posture on the front seating surface 6A and the backrest assembly 4, with the foot positioned forward and the head positioned backward.

図７は、後向き着座形態にある幼児搬送装置１００を例示する概略図である。背もたれ組立体４は前方へ傾斜し、子供を後向きに着座させることが出来る。   FIG. 7 is a schematic view illustrating the infant carrier apparatus 100 in a rearward seating configuration. The backrest assembly 4 can be tilted forward to seat the child backwards.

図８は、背もたれ組立体４が前方への水平な折畳み使用形態にある幼児搬送装置１００を例示する概略図である。背もたれ組立体４は前方へほぼ水平な姿勢に折り畳まれ、座席組立体６の前部着座面６Ａに近接している。ラッチ部４２２はハウジング８２の内部空洞８４の外に位置し、当接面８２９に接触し係合して（図４に示す）背もたれ組立体４がＤ２方向に回転するのを防ぐ。一方、管部４２に当接する当接面８２８は背もたれ組立体４がＤ１方向に回転するのを阻止する。この使用形態では、子供は後部着座面６Ｂと背もたれ組立体４との上にほぼ水平な眠る姿勢に横たわることが出来、足は後方に位置し、頭は前方に位置する。   FIG. 8 is a schematic view illustrating the infant carrier apparatus 100 in which the backrest assembly 4 is in a forward horizontal folding usage configuration. The backrest assembly 4 is folded forward in a substantially horizontal posture and is close to the front seating surface 6A of the seat assembly 6. The latch portion 422 is located outside the internal cavity 84 of the housing 82 and contacts and engages the abutment surface 829 to prevent the backrest assembly 4 from rotating in the D2 direction (shown in FIG. 4). On the other hand, the abutment surface 828 that abuts the tube portion 42 prevents the backrest assembly 4 from rotating in the direction D1. In this mode of use, the child can lie in a substantially horizontal sleeping position on the rear seating surface 6B and the backrest assembly 4, with the foot positioned backward and the head positioned forward.

背もたれ組立体４と背もたれ保持基部８は構造及び操作が簡単であり、経済的な製造コストで実現できる。また、背もたれ組立体４は、これを引っ張り所望の姿勢へ回転させることで容易に調整できる。
以上はベビーカー装置の実施形態を説明したが、本明細書に記載した機構及び特徴は、他の幼児搬送装置、例えば子供椅子、揺動装置などにも適用できる可能性がある。 The backrest assembly 4 and the backrest holding base 8 are simple in structure and operation and can be realized at an economical manufacturing cost. Further, the backrest assembly 4 can be easily adjusted by pulling it and rotating it to a desired posture.
Although the embodiment of the stroller device has been described above, the mechanisms and features described in the present specification may be applicable to other infant conveyance devices such as a child chair and a swing device.
