Abstract
A flat seat plate providing an upper surface which is in contact with a principal region of the lower surface of a seat portion for supporting the seat portion from below is integrated into a part of the body of a baby carriage. The seat plate is divided into three plate-type members, and adjacent ones of the plate-type members are hinged with each other on the respective lower surface sides thereof by flexible sheets. End surfaces of the plate-type members are butted against each other when the seat plate defines a uniform plane.
Claims16
A baby carriage that is collapsible in a direction of its width by a widthwise collapsing operation, comprising:
- a seat including a seat portion and a backrest portion that is deformable so as to allow said widthwise collapsing operation;
- a pair of side bars arranged on a lower surface of said seat portion along respective side thereof, wherein a spacing distance between said side bars is changeable in accordance with said widthwise collapsing operation;
- and
- a flat seat extending across said pair of side bars and providing an upper surface that is in supporting contact with a principal region of said lower surface of said seat portion,
- wherein said seat plate comprises a plurality of plate-type members of a relatively rigid material divided from one another by at least one dividing line extending along a front-to-back direction of said seat plate, and a hinge portion hinging adjacent one of said plurality of plate-type members with each other on respective lower surface thereof,
- wherein said plurality of plate-type members have respective edge surfaces that are butted against each other between said adjacent plate-type members when said upper surface of said seat plate defined a uniform plane,
- wherein at least one of said plate-type members comprises a major plate body and a substantially rigid spacer member independent of said major plate body and mounted on an edge therof to form a respective one of said edge surfaces, and
- wherein said major plate body has edge flange defining said edge surface thereof and extending along said front-to-back direction of said seat plate, said spacer member has a U-shaped cross-section with a channel formerd formed between two shanks thereof, and said spacer member is mounted on said edge flange with said edge flange received in said channel.

A baby carriage that can be collapsed widthwise, comprising:
- a carriage frame;
- two side bars connected to said frame and extending spaced apart and parallel to each other generally in a front-to-back longitudinal direction of said baby carriage;
- and
- a seat plate that is mounted on and extends between said two side bars;
- wherein said seat plate comprises:
- a plurality of substantially rigid plate members that extend in said longitudinal direction, are arranged adjacent one another respectively along at least one dividing line extending in said longitudinal direction, and have respective paired adjacent side edge surfaces spaced apart from each other with a gap therebetween and extending along said at least one dividing line,
- a hinge element arranged on respective bottom surfaces of said adjacently arranged plate members along said dividing line so as to bendably interconnect said adjacently arranged plate members, and
- a spacer member interposed between said adjacent side edge surfaces so as to span said gap and form a force-transmitting abutment of said adjacent side edge surfaces through said spacer member in cooperation with said hinge element when said plate members are aligned with each other in a substantially horizontal plane,
- wherein at least a first one of said plate members includes a side edge flange extending along said dividing line on a plane substantially perpendicular to a major plane of said first plate member and forming said first side edge surface, and wherein said spacer member has therein a groove extending therealong and is mounted with said edge flange received in said groove.

A baby carriage that can be collapsed widthwise, comprising:
- a carriage frame;
- two side bars connected to said frame and extending spaced apart and parallel to each other generally in a front-to-back longitudinal direction of said baby carriage;
- and
- a seat plate that is mounted on and extends between said two side bars;
- wherein said seat plate comprises:
- a plurality of substantially rigid plate members that extend in said longitudinal direction, are arranged adjacent one another respectively along at least one dividing line extending in said longitudinal direction, and have respective paired adjacent side edge surfaces spaced apart from each other with a gap therebetween and extending along said at least one dividing line,
- a hinge element arranged on respective bottom surfaces of said adjacently arranged plate members along said dividing line so as to bendably interconnect said adjacently arranged plate members, and
- a spacer member interposed between said adjacent side edge surfaces so as to span said gap and form a force-transmitting abutment of said adjacent side edge surfaces through said spacer member in cooperation with said hinge element when said plate members are aligned with each other in a substantially horizontal plane, and
- further comprising two support brackets respectively arranged to provide said connecting of said side bars to said carriage frame, wherein said seat plate is mounted on said side bars with respective widthwise outer ones of said plate members respectively rotatably receiving said side bars such that said outer plate members are freely rotatable about axes of said side bars, said support brackets have rearward ends connected to said side bars at respective center portions thereof along said longitudinal direction, said carriage frame comprises front legs and rear legs, and said support brackets have forward ends rotatably connected to said front legs.
