　検知手段８０となるベース板８２上に乳幼児が乗車するとベース板８２と座部５６（４４）の間の隙間がなくなり、ベース板８２に接続した索条体９４が弾性体９８の付勢方向と反対方向に引っ張られる。索条体９４に接続したリンク部材９６が下方へ移動して、テーパ部９６１の縮径から拡径にスライダ９２３が移動してロック解除防止部材９２がロック孔９１に向けて前進して係合片９２２が嵌め合わさる。これにより、支持部材５４の挿入穴５４１からロッド２６１を引き抜くことができず、解除部７０によるシートの取り外し動作を防止できる。
　なお本発明のベビーカーは、ベビーカー本体に着脱可能なシートとして乳児ベッドの代わりにペット用ベッドを適用すればペットカートとして使用できる。ペット用ベッドは乳児ベッドと同様な着脱構造であり、乳児ベッドと同一の支持部材及び検知手段を用いることにより、シートにペットを乗せたままシートをベビーカー本体から取り外すことを防止できる。従ってペット用ベビーカー又はペットカートの使用時の安全性を高めることができる。 [Effect]
The operation of the stroller of the present invention according to the above configuration will be described below.
(When the baby is not on the seat)
Since the base plate 82 is urged in the direction of separating from the seat portion 56 (44) by the elastic body 98 of the release preventing portion 90, between the base plate 82 serving as the detection means 80 and the seat portion 56 (44) A gap is formed. When the infant is not on the seat (absent), this gap is maintained. The engagement piece 922 of the release prevention portion 90 is not fitted in the lock hole 91. Therefore, the release operation of the sheet by the release unit 70 can be performed.
(When the baby is on the seat)
When the baby gets on the base plate 82 serving as the detection means 80, the gap between the base plate 82 and the seat portion 56 (44) disappears, and the cord 94 connected to the base plate 82 It is pulled in the opposite direction. The link member 96 connected to the cord body 94 moves downward, and the slider 923 moves from the diameter reduction of the taper portion 961 to the diameter increase, and the lock release preventing member 92 advances toward the lock hole 91 and engages. The pieces 922 fit together. As a result, the rod 261 can not be pulled out from the insertion hole 541 of the support member 54, and the removal operation of the sheet by the release unit 70 can be prevented.
The stroller according to the present invention can be used as a pet cart if a pet bed is applied as a removable seat to the stroller main body instead of the baby bed. The pet bed has a detachable structure similar to the baby bed, and by using the same support member and detection means as the baby bed, it is possible to prevent the seat from being removed from the stroller main body while the pet is placed on the seat. Therefore, the safety when using the pet stroller or pet cart can be enhanced.
［変形例１］電気式検知手段
　図９はベビーカーの変形例１の説明図であり、（１）は検知手段の説明図、（２）は解
除防止部の説明図である。変形例１の検知手段８０Ａは、シート上の乳幼児を検出可能なセンサーを採用している。
　具体的な検出手段８０Ａは、乳幼児の体重を検出可能な圧力センサー、乳幼児を検知可能な赤外線センサー、乳幼児の体温を検出可能な温度センサーのいずれか１つ、又は２つ以上を組み合わせた構成である。センサーはシート内に取り付けて、乳幼児の存否（乗車又は乗車していない）を確認できるように構成している。
　また解除防止部９０Ａはロック解除防止部材９２Ａと駆動部９９を備えている。ロック解除防止部材９２Ａは、主面を水平に配置してロッド２６１のロック孔９１に向けて進退移動して、先端が孔に嵌る部材である。
　駆動部９９は検出手段８０Ａとなるセンサーと無線又は有線を介して電気的に接続している。駆動部９９は検出手段８０Ａの測定値に基づいて、ロック解除防止部材９２Ａの進退移動を制御している。具体的な駆動部９９の制御は、検出手段８０Ａによる乳幼児存在の検知信号を受信した場合、ロック解除防止部材９２Ａをロック孔９１に向けて伸長して嵌合する。これにより挿入穴５４１からロッド２６１の引き抜きが阻止される。
　一方、検出手段８０Ａによる乳幼児不在の検知信号を受信した場合、ロック解除防止部材９２Ａをロック孔９１から後退させて嵌合を解除する。これにより、挿入穴５４１からロッド２６１を解除部７０により引き抜くことができる。 [Modification 1] Electric detection means FIG. 9 is an explanatory view of a first modification of the stroller, (1) is an explanatory view of the detection means, and (2) is an explanatory view of the release preventing portion. The detection means 80A of the first modification employs a sensor capable of detecting an infant on a seat.
The specific detection means 80A is configured by combining one or more of a pressure sensor capable of detecting the weight of an infant, an infrared sensor capable of detecting an infant, and a temperature sensor capable of detecting the temperature of the infant. is there. The sensor is mounted in the seat so that the presence or absence of a baby (not boarding or boarding) can be confirmed.
In addition, the release preventing unit 90A includes a lock release preventing member 92A and a drive unit 99. The lock release preventing member 92A is a member in which the main surface is arranged horizontally and moved forward and backward toward the lock hole 91 of the rod 261 so that the tip thereof is fitted in the hole.
The drive unit 99 is electrically connected to the sensor serving as the detection unit 80A via wireless or wire. The drive unit 99 controls the forward / backward movement of the lock release preventing member 92A based on the measurement value of the detection means 80A. Specifically, in the control of the drive unit 99, when the detection signal of the presence of the baby by the detection means 80A is received, the lock release preventing member 92A is extended and fitted to the lock hole 91. This prevents the rod 261 from being pulled out of the insertion hole 541.
On the other hand, when the detection signal of the absence of the baby by the detection means 80A is received, the lock release preventing member 92A is retracted from the lock hole 91 to release the fitting. Thus, the rod 261 can be pulled out of the insertion hole 541 by the release portion 70.
　このような変形例１のベビーカーによれば、シート内に取り付ける検知手段を小型化して大きな収容スペースを確保できるとともに、乳幼児に接触して不快感を与えるおそれがない。
　またシート上の乳幼児を検知して、ベビーカー本体から乳幼児を乗せた状態でシートを取り外すことを防止することができる。 According to the stroller of the first modification, the detection means mounted in the seat can be downsized to secure a large storage space, and there is no possibility that the baby may come in contact with discomfort.
In addition, it is possible to detect the infant on the seat and to prevent the seat from being removed in the state where the infant is placed from the stroller main body.
［変形例２］装着部と解除部の間の解除防止部
　図１０はベビーカーの変形例２の説明図であり、（１）はロック解除防止部材の斜視図、（２）は解除防止操作の説明図である。変形例２の解除防止部９０Ｂは、解除部によるシートの取り外しを阻止する構成を採用している。
　具体的な解除防止部９０Ｂの構成は、ロッド２６１が貫通する長孔９２４と、解除ボタン７６とロッド２６１の間に配置して解除部７０の解除動作を阻止する突起部９２５を備えてロッド２６１に向けて進退移動可能なロック解除防止部材９２Ｂと、ベース板８２の両側面に一端を接続した索条体９４（以下、図１の構成と同じ）と、索条体９４の他端と接続しロック解除防止部材９２Ｂと接触してロッド２６１に向けてロック解除防止部材９２Ｂを進退移動させるリンク部材９６と、一端を支持部材５４に固定し、他端をリンク部材９６に固定して索条体９４を引き上げる方向に付勢してベース板８２とシートの底面の間に隙間を形成する弾性体９８からなる。 [Modification 2] Release prevention portion between the mounting portion and the release portion FIG. 10 is an explanatory view of a second modification of the stroller, (1) is a perspective view of the lock release prevention member, and (2) is a release prevention operation FIG. The release prevention unit 90B of the second modification employs a configuration that prevents the release of the sheet by the release unit.
Specifically, the configuration of the release prevention portion 90B includes a long hole 924 through which the rod 261 passes, and a projection 925 disposed between the release button 76 and the rod 261 to block the release operation of the release portion 70. The lock release preventing member 92B movable forward and backward, the cord 94 having one end connected to both sides of the base plate 82 (hereinafter the same as the configuration of FIG. 1), and the other end of the cord 94 Link member 96 for moving the lock release preventing member 92B forward and backward toward the rod 261 in contact with the lock release preventing member 92B, and fixing one end to the support member 54 and fixing the other end to the link member 96 It comprises an elastic body 98 which urges the body 94 in a pulling direction to form a gap between the base plate 82 and the bottom of the sheet.
　このような構成の解除防止部９０Ｂは、乳児が乗車していない（不在）ときロッド２６１と解除ボタン７６の間に突起部９２５が配置されていないため、解除部７０によるシートをベビーカー本体２０から取り外す操作が可能となる。
　一方、乳児が乗車している（存在）とき、ロック解除防止部材９２Ｂの進出動作によりロッド２６１と解除ボタン７６の間に突起部９２５が配置される。このため、解除部７０によるシートをベビーカー本体２０から取り外す操作が阻止される。
　このような変形例２のベビーカーによれば、電源を用いずに半永久的にシート上の乳幼児を検知して、ベビーカー本体から乳幼児を乗せた状態でシートを取り外すことを防止することができる。 Since the protrusion 925 is not disposed between the rod 261 and the release button 76 when the baby is not in the vehicle (absent), the release prevention unit 90B having such a configuration does not have the seat by the release unit 70 from the stroller main body 20 It becomes possible to remove it.
On the other hand, when the baby is in the vehicle (present), the protrusion 925 is disposed between the rod 261 and the release button 76 by the advancing operation of the lock release preventing member 92B. Therefore, the operation of removing the seat from the stroller main body 20 by the release unit 70 is blocked.
According to the stroller of the second modification, the infant on the seat can be detected semipermanently without using the power supply, and the seat can be prevented from being removed while the infant is placed on the stroller main body.
