Abstract: Comprises a frame (1) with the legs (7) of the handlebar slideable on the front feet (6) and from which legs (7) is actuated the device for locking and unlocking the folding, the lower ends of the legs (7) of the handlebar being connected to the rear feet (10) by means of two hingedly (15) crossed arms (13 and 14). The upper ends of the front feet (6) each include a guiding strap (12) to which are hingedly connected respective vertical arms (11) which connect said feet (6) to the rear feet (10). The frame (1) bears a seat (2), a back (3) hingedly (4) connected to same, an armrest (19), and a front handrail (40). The pushchair is characterized in that the seat (2) is hingedly (18) connected at the rear, by its sides (5), to the vertical arms (11), at a middle portion, to each of the armrests (19), by means of a tie rod (20), and, at its front end, through further respective tie rods (21), to the front end (16) of the legs (7) of the handlebar.

Abstract: A collapsible baby carriage includes a foldable frame including a cradle seat defined by a pair of seat support arms each having one end pivotally connected to a lower end of a guide bracket with a guide bracket having an upper end connected to a pivot member allowing the front legs of the carriage to be folded intermediate their ends a pair of vertical arms are provided each having one end connected to a respective leg of a second pair of legs and an opposite end connected to a leg of the first pair between said pivot member and a second end of a leg of the first pair; the frame includes a pair of rods each having one end rotatably connected to one of the vertical arms intermediate the ends thereof on one side of the frame and a second end pivotally connected to a respective one of the seat support arms intermediate the ends thereof.

Abstract: A locking and unlocking device is provided for the U-shaped handle bar of a baby carriage which slides between folded and unfolded positions on front legs of the carriage. The handlebar has spring hooks which engage pins in the respective legs in the unfolded position and the device includes a manually rotatable disc in the central section of the handlebar connected to the hooks by cables for releasing the hooks from the pins. A manually releasable dog is provided for locking the disc against rotation.

Abstract: The invention refers to some improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar. With these improvements, a very complete, light children's pushchair with a simple structure and very compact folding up is obtained. These advantages are achieved by structuring the frame on the basis of a linked triangulation formed on each side by the rear (3) and front (1) legs, and by a base frame (5), the rear leg (3) being linked by its upper end (9) on a solidly jointed flange (7) of the lower end of the brace members of the handlebar (6) and along which it slides guided by the front leg (1), the front (1) and rear (3) legs being related to each other by the base frame (5) and the front legs (1) being finished off at the top with a guiding flange (8) along which the corresponding brace member of the handlebar (6) slides.

Abstract: A foldable baby stroller chassis includes a pair of front legs with a plate pivotally connected to the upper end of the legs and a pair of back legs having upper ends pivotally connected to the plate. A member is provided having a lower end with a clamp connection to the lower ends of the front legs and an upper bent arm portion with an intermediate pivotal connection to the back leg. A rear seat portion having an intermediate portion pivotally connected to the upper end of the bent arm portion and a plate, which is preferably triangular in shape, is connected to the rear seat portion adjacent its lower end and has an apex projecting forwardly in which a handle is connected pivotally. A joining plate is provided on each side of the upper end of the back legs and pivotally connected to the upper end of the front legs and the upper ends of the back legs. A bushing is carried on each side of a handle and extends and is movable relative to the handle.

Abstract: A foldable stroller for children is disclosed having a back formed by several longitudinal rigid and padded portions which are articulated together by means of folds. Two supporting divider portions which articulatedly connect the back supports with the frame, permit two degrees of inclination for the back. The stroller is strengthened by the employment of front and rear, articulated crossed rods. The folding control of the stroller is effected by a pair of cross pieces split into two articulated sections and a common control bar. The cross pieces are placed between the side supports of the back. When unfolded, the cross pieces support the back. The control bar, when raised, operates to fold the stroller.
