Child support apparatus

摘要

An apparatus for seating a child comprising a seat and a foldable frame for supporting the seat. The frame comprises on left and rights sides: a first and a second frame member connected by a hinge assembly and relatively pivotal through substantially 180 degrees between an unfolded condition and a folded condition, and a third frame member connected to the hinge assembly and pivotal relative to the first and second frame members by less than 180 degrees between an unfolded condition and a folded condition. The first and second frame members are aligned and on opposite sides of the hinge assembly when unfolded and parallel and on the same side of the hinge assembly when folded. The third frame member is parallel with the first and second frame members when folded to provide a compact folded apparatus.

1. An apparatus for seating a child comprising a seat and a foldable frame for supporting the seat, the frame comprising:
a first and a second frame member connected by a hinge assembly and relatively pivotal through substantially 180 degrees between an unfolded condition and a folded condition by pivotal movement of the first frame member over the hinge assembly; and a third frame member connected to the hinge assembly and pivotal relative to the first and second frame members by less than 180 degrees between an unfolded condition and a folded condition; wherein the hinge assembly comprises:
a first hinge part fixed to the first frame member and a second hinge part fixed to the second frame member, the first and second hinge parts being arranged to pivot about a first eccentrically mounted pivot pin which is sufficiently off-set above an axis of the first and second frame members to allow the first and second frame members to pivot between an unfolded condition in which the first and second frame members are generally aligned and located on opposite sides of the hinge assembly and a folded condition in which the first and second members are generally parallel and located on the same side of the hinge assembly; anda third hinge part fixed to the third frame member and arranged to pivot about a second pivot pin which is sufficiently off-set from the first pivot pin to allow pivotal movement of the third frame member relative to the first and second frame members between an unfolded condition in which the third frame member is angled relative to the first and second frame members and a folded condition in which the third frame member is generally parallel with the first and second frame members and located on the same side of the hinge assembly as the first and second frame members;wherein the first hinge part has an asymmetric profile relative to the first pivot pin and pivotal movement of the first and second hinge parts between the unfolded and the folded conditions varies the spacing between the asymmetric profile and the second pivot pin.
