Abstract: A baby carriage includes: a pair of front legs extending in an up-down direction and having front wheels in their respective lower parts; a pair of push bars having their respective lower ends pivotally connected to upper ends of the front legs through pivot shafts, respectively; opened state lock means for locking an opened state of the baby carriage with the push bars aligned approximately linearly with respect to the front legs, respectively; closed state lock means for locking a folded state of the baby carriage with the push bars pivoted forward to a position where upper ends of the push bars get close to the front legs, respectively; and a dome-shaped canopy having its both ends in a width direction supported by the pair of push bars, respectively.

Abstract: A baby carriage includes a body and a seat hammock. The body includes a pair of seat surface support bars extending in a front-rear direction for supporting a seat surface portion of the seat hammock, and a pair of backrest surface support bars extending in an up-down direction for supporting a backrest surface portion of the seat hammock. The seat hammock has a front receiving portion at a front end of the seat surface portion for disengageably receiving respective front ends of the pair of seat surface support bars, and has a rear receiving portion at an upper end of the backrest surface portion for disengageably receiving respective upper ends of the pair of backrest surface support bars. In this baby carriage, the seat hammock that forms a seat can be easily attached to and detached from the body.

Abstract: Each element of opened/closed state lock means is arranged around each of pivot shafts that respectively pivotally connect front legs and push bars. In a folded state of a baby carriage, lower ends of the push bars do not protrude above upper ends of the front legs. The lower ends of the push bars and the upper ends of the front legs are in contact with each other and are not separated from each other both in an opened state and folded state of the baby carriage. The baby carriage can implement reduction in weight with a simple structure and reduction in height of the baby carriage in the folded state, and also can prevent problems such as pinched fingers.

Abstract: A folding baby carriage comprises a body so constituted that a seat and a backrest part approach each other in a folding operation, and a luggage basket positioned under the seat. The luggage basket comprises a front frame extending backward and forward under the seat, a rear frame turnably connected to a rear end of the front frame and extending backward and forward, and a lock mechanism preventing the rear frame being turned around the front frame. The rear frame is turned so as to take a lower position in which a rear part of the luggage basket is opened, a horizontal position in which it extends almost horizontally, and an upper position in which its rear end approximates the backrest part. The lock mechanism comprises horizontal position fixing means for fixing the rear frame in the horizontal position.

Abstract: A seat carriage body comprises a front leg, a rear leg, a push rod, and position fixing means. An upper end of the front leg is turnably connected to an upper end of the rear leg through a first shaft. A front end member of the push rod is connected to the front leg such that it can be displaced along the front leg at the time of a folding operation. A middle part of the push rod is turnably connected to the rear leg through a second shaft. The position fixing means fixes a positional relation among the front leg, the rear leg and the push rod in both open and folded states.

Abstract: A wheel simultaneous brake mechanism for simultaneously braking two wheels includes two respective engaging members that are selectively movable between an engaged position and a disengaged position for selectively braking or releasing the two wheels. Each engaging member is biased by a spring toward its respective engaged position. The two engaging members are connected to one another in a manner transmitting a tensile force therebetween by a wire, so that the engagement or release of both engaging members can be actuated together in unison.

Abstract: A folding baby carriage comprises a pair of seating surface supporting side bars extending back and forth along both sides of a seating surface in order to support the seating surface from beneath. Each seating surface supporting side bar has a rigid inward extending portion extending toward the inside so as to support the seating surface from beneath, at a rear portion thereof. The inward extending portion is formed by bending a rear end portion of the seating surface supporting side bar toward the inside.

Abstract: A baby-care implement comprises a hood which covers a top of a seat thereof. The hood comprises a mounting base fixed to a body of the baby-care implement, a first hood bone whose lower end is turnably connected to the mounting base, a second hood bone positioned on the inner side of the first hood bone, whose lower end is turnably connected to the mounting base, a third hood bone positioned on the inner side of the second hood bone, a first hood sheet mounted on the first hood bone and extending backward and forward, and a second hood sheet mounted on the second hood bone, overlapping the inner side of the first hood sheet and extending backward and forward. The second hood sheet comprises one end in the back-and-forth direction which is separated from the first hood sheet and the other end which is connected to the first hood sheet.

Abstract: The folding baby carriage is foldable so that four wheels approach each other back and forth and from side to side. The baby carriage includes a lower frame structure that is positioned above the four wheels to form a seating surface portion of a seat and that is foldable so as to approach back and forth and from side to side with the four wheels, and an inverted U-shaped member extending to rise upward from both sides of the seating surface portion. The inverted U-shaped member remains on a single plane in both the folded state and the opened state without bending out of this plane, but lower ends of the inverted U-shaped member come closer together in the folded state.
