Reversible foldable push-chair for children

Claim 2

A reversible foldable push-chair of the slidable umbrella type adapted for folding; or when unfolded displaying either a facing rearward, "facing mother" position, or a facing forward, "look ahead" position, supporting a hammock and comprising on each side of the hammock, a tipping core, two wheel carrier branches hingedly mounted to said tipping core and having a wheel at one end of each of said branches, a pushing arm slidably mounted and traversing said tipping core so that said pushing arm can slidably move through said tipping core and in a tipping motion in relation to the push-chair thereby rotating the position of said tipping core, and link means connecting said pushing arm to said two wheel carrier branches whereby dependent upon the direction of the tipping motion of the handle and of rotation of the position of said tipping core, the push-chair is spread out for displaying and locked in either a "facing mother" position or in a "look ahead" position.

Claim 3

The push-chair of claim 1 further characterized by said tipping core having a groove near the hinged connection of each of said branches with said core, for receiving and locking in each of said branches, each of said branches being of an arcuate shape to present a portion receivable in one of said grooves and another portion carrying said wheel positioned nearer to the centerline of the push-chair when the push-chair is in the folded position.

Claim 4

The push-chair of claim 1 further characterized by said link means including forks articulated to said branches and to one another in the form of a pair of compasses and lying in alignment with each other when the push-chair is in either the "facing mother" position or the "look ahead" position, a link connecting said forks to said pushing arm, and a locking means to enable said forks to be held in alignment with each other in the unfolded displaying position of the push-chair.

Claim 5

The push-chair of claim 1 further characterized by a longitudinal rod carried by said core on each side of the push-chair in a pivotable manner, said longitudinal rod receiving the hammock thereon, and adjusting means to adjust the position of said longitudinal rod with respect to said core.

Claim 6

The push-chair of claim 1 further characterized by said branches being telescopically extendable at the ends at which said wheels are mounted.

Claim 7

A reversible foldable push-chair of the slidable umbrella type adaptable for folding or for unfolding and spreading out in a facing rearward, "facing mother" position or a facing forward, "look ahead" position, supporting a hammock and comprising on each side of the hammock a tipping core, two wheel carrier branches articulated to said core, a pushing arm slidably mounted and traversing said tipping core so that said pushing arm can slidably move through said tipping core and in a tipping motion in relation to the push-chair thereby rotating the position of said tipping core, link means connecting said pushing arm to said two branches, said tipping core having a groove near the articulation connection of each of said branches with said core for receiving and locking each of said branches in its respective one of said grooves, said link means including forks articulated to said branches and to one another in the form of a pair of compasses and lying in alignment with each other when the push-chair is in either the "facing mother" position or the "look ahead" position, a link connecting said forks to said pushing arm, said link having a slide groove formed to articulate said link with said pushing arm so that when the push-chair is unfolded and spread out the stroke of said link is tranformed to a combined simultaneous lifting and inclination movement, such inclination being effected as desired either in a "facing mother" direction or in a "look ahead" direction.

Claim 8

A reversible foldable push-chair of the slidable umbrella type adaptable for folding or for unfolding and spreading out in a facing rearward, "facing mother" position or a facing forward, "look ahead" position, supporting a hammock and comprising on each side of the hammock a tipping core, two wheel carrier branches articulated to said core, a pushing arm slidably mounted and traversing said tipping core so that said pushing arm can slidably move through said tipping core and in a tipping motion in relation to the push-chair thereby rotating the position of said tipping core, link means connecting said pushing arm to said two branches, said tipping core having a groove near the articulation connection of each of said branches with said core for receiving and locking each of said branches in its respective one of said grooves, said link means including forks articulated to said branches and to one another in the form of a pair of compasses and lying in alignment with each other when the push-chair is in either the "facing mother" position or the "look ahead" position, a link connecting said forks to said pushing arm, said link having a slide groove formed to articulate said link with said pushing arm so that when the push-chair is unfolded and spread out the stroke of said link is tranformed to a combined simultaneous lifting and inclination movement, such inclination being effected as desired either in a "facing mother" direction or in a "look ahead" direction.

Claim 9

The push-chair of claim 6 further characterized by pivot points at which said forks are articulated to said branches, and means to lower said points to allow use of at least one of said forks as a footboard.
