A baby carriage includes a body and a seat hammock. The body has wheels, and the seat hammock includes a seat surface portion and a backrest surface portion and is detachably mounted on the body to form a seat. In a baby carriage body 10 shown in
The baby carriage 10 includes, as a basic structure, a pair of front legs 12, a pair of rear legs 14, a pair of seat surface support bars 15, a pair of backrest surface support bars 16, a pair of push bars 17, width-direction connecting means 18, 19, and opened/closed state lock means 20. The front legs 12 extend in an up-down direction and have the front wheels 11 at their respective lower parts. The rear legs 54 extend in the up-down direction and have the rear wheels 13 at their respective lower parts. The rear legs 14 are provided so as to cross the front legs 12, and are pivotally connected to the front legs 12 at their crossing portions through pins, respectively. The seat surface support bars 15 extend in a front-back direction, and front parts of the seat surface support bars 15 are pivotally connected to upper parts of the rear legs 14, respectively. The backrest surface support bars 16 extend in the up-down direction, and lower parts of the backrest surface support bars 16 are pivotally connected to rear parts of the seat surface support bars 15, respectively. The push bars 17 extend in the up-down direction and respectively cross the backrest surface support bars 16. Lower ends of the push bars 17 are pivotally connected to upper ends of the front legs 12 through pivot shafts, respectively. The push bars 17 are pivotally connected to the backrest surface support bars 16 at their crossing portions, respectively. The width-direction connecting means 18, 19 connects the left and right sides of the baby carriage, each of the left and right sides being formed by the front leg 12, the rear leg 14, the seat surface support bar 15, the backrest surface support bar 16, and the push bar 17. The opened/closed state lock means 20 locks an opened state and closed state (folded state) of the baby carriage body 10 by inhibiting pivoting of the push bars 17 with respect to the front legs 12.
The width-direction connecting means 18, 19 are structured so as to reduce the gap between the right and left sides of the baby carriage body in the folded state of the baby carriage.
The seat hammock that forms a seat is not shown in
As shown in
As can be seen from
The front receiving portion 35 and the rear receiving portion 36 may be in any form as long as they can disengageably receive the front ends of the seat surface support bars 15 and the upper ends of the backrest surface support bars 16, respectively. In the illustrated embodiment, the front receiving portion 35 and the rear receiving portion 36 have, as a simpler structure, a bag shape having their respective ends (front end or upper end) closed. In this case, the seat hammock 30 can be attached to the baby carriage body 10 by simply fitting the bag-like front receiving portion 35 and rear receiving portion 36 onto the ends of the seat surface support bars 15 and backrest surface support bars 16, respectively. Moreover, the seat hammock 30 can be easily detached from the baby carriage body 10 by removing the front receiving portion 35 and the rear receiving portion 36 from the ends of the seat surface support bars 15 and the backrest surface support bars 16, respectively.
By using the bag-like front receiving portion 35 and rear receiving portion 36, an engaged state of the front receiving portion 35 and the seat surface support bars 15 and an engaged state of the rear receiving portion 36 and the backrest support bars 16 can be reliably maintained by the weight of an infant or small child when the infant or small child sits on the seat hammock 30.
In order to prevent the boundary portion between the seat surface portion 31 and the backrest surface portion 32 of the seat hammock 10 from getting away from the baby carriage body 10, the seat hammock 30 of the illustrated embodiment includes connecting means 37 for detachably connecting the boundary portion to the baby carriage body 10. For example, a string, a hook and loop fastener, or the like can be used as the connecting means 37.
The hanging cloth 34 has a function to make the space under the seat invisible from the front, and a function to prevent the legs of an infant or small child from contacting the body components located in the space under the seat. The former function is effective, for example, when a baggage basket is mounted under the seat, and the latter function works more efficiently in the case where the hanging cloth 34 is connected to the body 10 by any connecting means.
In a preferred embodiment, the seat surface portion 31 of the seat hammock 30 has a pair of front receiving portions 35 located apart from each other on the left and right sides. When the pair of front receiving portions 35 individually receive the pair of seat surface support bars 15, respectively, the width-direction dimension of the seat surface portion 31 is fixed, whereby the shape can be stably maintained. Similarly, the backrest surface portion 32 of the seat hammock 30 preferably has a pair of rear receiving portions 36 located apart from each other on the left and right sides. When the pair of rear receiving portions 36 individually receive the pair of backrest surface support bars 16, respectively, the width-direction dimension of the backrest surface portion 32 is fixed, whereby the shape can be stably maintained.
Although an embodiment of the present invention has been described above with reference to the figures, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the above described and illustrated embodiment within the same scope or an equivalent scope as in the present invention.
The present invention can thus be advantageously used in a baby carriage having a baby carriage body and a seat hammock.
