Abstract
Abstract A folding baby carriage composed of an articulated tubular metal framework comprises a pair of folding sides (10) which are interconnected by means of a folding base frame (12) and by means of a steering handle (13) which is slideable with respect to the sides (10), and a seat (14) cum-backrest (15) structure fixed to a pair of frames (16, 17) articulated one to the other at an intermediate point (18) of the frame (16) which in its forward part is pivoted at (29) to the steering handle (13) and in its rear part at (25) to the sides (10) and to the base frame (12). The frame (17) is connected to the sides (10) by linkwork (30) so that the backrest (15) can be moved between an upright position and a reclined position, provision also being made between the sides (10) and the steering handle (13) for disengageable reciprocal engagement means adapted to determine in a stable manner the erected and folded positions of the baby carriage.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
356 words
A foldable baby carriage formed of an articulated tubular metal framework and being adjustable into a stable operative position and a stable folded position, comprising: first and second connection members; right and left side frame members each side frame member having first and second rods, each first rod and each second rod connected at an upper end to a pivot associated with one of said first and second connection members; a U-shaped base frame positioned between and connecting with each of said first rods, said U-shaped base frame having a first foldable leg member having a central articulated joint and second foldable leg member having a central articulated joint, each of said first and second foldable leg members being pivotally connected to one of said second rods; a U-shaped steering handle member having a first steering handle leg member and a second steering handle leg member, each handle leg member being slidably connected to an upper portion of said side frame members through a slide opening in respective first and second connection members; a seat and backrest assembly including a backrest structure fixed to first and second seat frame members and fixed to a backrest frame, said backrest frame being articulated to an intermediate point in each of said first and second seat frame members, each of said first and second seat frame members being pivotally connected at a forward part to a lower portion of respective first and second steering handle leg members and each of said first and second seat frame members being pivotally connected at a rear part to respective said first rods of said side frame members, and backrest frame being connected to respective said side frame members by link work assemblies so that the backrest may be moved between an upright and a reclined position; and, engagable reciprocal engagement means for fixing the position of the slidable U-shaped steering handle member relative to the side frame members for maintaining the carriage in a stable operative position and for releasing the U-shaped steering handle member relative to the side frame members for adjustment of the carriage into a fixed stable folded position.
Claim 2
Dependent Claim
356 words
A foldable baby carriage formed of an articulated tubular metal framework and being adjustable into a stable operative position and a stable folded position, comprising: first and second connection members; right and left side frame members each side frame member having first and second rods, each first rod and each second rod connected at an upper end to a pivot associated with one of said first and second connection members; a U-shaped base frame positioned between and connecting with each of said first rods, said U-shaped base frame having a first foldable leg member having a central articulated joint and second foldable leg member having a central articulated joint, each of said first and second foldable leg members being pivotally connected to one of said second rods; a U-shaped steering handle member having a first steering handle leg member and a second steering handle leg member, each handle leg member being slidably connected to an upper portion of said side frame members through a slide opening in respective first and second connection members; a seat and backrest assembly including a backrest structure fixed to first and second seat frame members and fixed to a backrest frame, said backrest frame being articulated to an intermediate point in each of said first and second seat frame members, each of said first and second seat frame members being pivotally connected at a forward part to a lower portion of respective first and second steering handle leg members and each of said first and second seat frame members being pivotally connected at a rear part to respective said first rods of said side frame members, and backrest frame being connected to respective said side frame members by link work assemblies so that the backrest may be moved between an upright and a reclined position; and, engagable reciprocal engagement means for fixing the position of the slidable U-shaped steering handle member relative to the side frame members for maintaining the carriage in a stable operative position and for releasing the U-shaped steering handle member relative to the side frame members for adjustment of the carriage into a fixed stable folded position.
Claim 3
Dependent Claim
130 words
A folding baby carriage according to claim 1, wherein: the engagement means includes hooks associated with the upper end of said side frame members; first and second pins associated with an upper portion of respective first and second steering handle leg members; a lower pin associated with a lower end of one of said first and second steering handle leg members; and, lower slidable hook means connected to a lower portion of one of said right and left side frame members for sliding, against the action of a spring, with respect to one of said side frame members for engagement with said lower pin when the carriage is in an operative position and for engaging one of said first and second pins when the carriage is in a folded position.
Claim 4
Dependent Claim
77 words
A foldable baby carriage according to claim 1, further comprising: a rigid foot rest fixed to a footrest U-shaped member, the foot rest U-shaped member having first and second foot rest U-shaped member legs, each foot rest U-shaped member leg being pivoted, at foot rest U-shaped leg ends, proximal to the forward part of the seat frame and adjacent respective said first and second seat frame members, to respective said second rods of said side frame members.
Claim 5
Dependent Claim
