Abstract

A portable stroller that includes a collapsible frame that has two Y-shaped support units and a plurality of links which collapsibly mount a seat section thereon.

Claims

1. A stroller for carrying a child comprising:

A) a seat section on which a child rests when in use, the seat section including a first end which is a forward end when the seat section is in use, a second end which is a rear end when the seat section is in use, a first side which extends between the first end of the seat section and the second end of the seat section, a second side which extends between the first end of the seat section and the second end of the seat section, and a longitudinal axis which extends between the first end of the seat section and the second end of the seat section;

B) a frame section to which the seat section is attached, the frame section including

(1) a handle unit which is located adjacent to the second end of the seat section and which includes

(a) a first cross bar attached to the second end of the seat section and which extends between the first side of the seat section and the second side of the seat section,

(b) a second cross bar that is spaced apart from the first cross bar and which extends between the first side of the seat section and the second side of the seat section,

(c) a first support arm which is located adjacent to the first side of the seat section and which connects one end of the first cross bar to one end of the second cross bar, the first support arm including a first end which is connected to the one end of the second cross bar and a second end which is spaced apart from the one end of the first cross bar, and

(d) a second support arm which is located adjacent to the second side of the seat section and which connects a second end of the second cross bar to a second end of the first cross bar, the second support arm including a first end which is connected to the second end of the second cross bar and a second end which is spaced apart from the second end of the first cross bar,

(2) a first support element having a first end pivotably connected to the first support arm adjacent to the one end of the first cross bar of the handle unit and a second end,

(3) a second support element having a first end pivotably connected to the second support arm adjacent to the second end of the first cross bar of the handle unit and a second end,

(4) a first connecting link located adjacent to the first side of the seat section and including

(a) a first end pivotably connected to the second end of the first support element, and

(b) a second end located adjacent to the first side of the seat section,

(5) the second end of the first support arm being pivotably connected to the first connecting link adjacent to the first side of the seat section,

(6) a second connecting link located adjacent to the second side of the seat section and including

(a) a first end pivotably connected to the second end of the second support element, and

(b) a second end located adjacent to the second side of the seat section,

(7) the second end of the second support arm being pivotably connected to the second connecting link adjacent to the second side of the seat section,

(8) a Y-shaped support unit which includes

(a) a first leg having a first end pivotably connected to the second ends of the first support element and the first connecting link, and a second end,

(b) a second leg having a first end pivotably connected to the second ends of the second support element and the second connecting link, and a second end,

(c) a first transverse leg having one end connected to the second end of the first leg of the Y-shaped support unit and a second end,

(d) a second transverse leg having one end connected to the second end of the second leg of the Y-shaped support unit and a second end, the second end of the first transverse leg being located closely adjacent to the second end of the second transverse leg and being located adjacent to the longitudinal axis of the seat section, and

(e) a longitudinal leg which extends in the direction of the longitudinal axis of the seat section and which has a first end pivotably connected to the second ends of the first and second transverse legs of the Y-shaped support unit, and a second end, the longitudinal leg of the Y-shaped support unit extending beyond the first end of the seat section in a set up configuration, and

(9) a block Y-shaped support unit which includes

(a) a first leg having a first end pivotably connected to the second end of the first connecting link and a second end,

(b) a second leg having a first end pivotably connected to the second end of the second connecting link and a second end,

(c) a first transverse leg having a first end connected to the second end of the first leg of the block Y-shaped support unit and a second end,

(d) a second transverse leg having a first end connected to the second end of the second leg of the block Y-shaped support unit and a second end,

(e) the second ends of the first and second legs of the block Y-shaped support unit being spaced apart from the first end of the seat section,

(f) a first longitudinal arm having a first end connected to the second end of the first transverse leg of the block Y-shaped support unit and a second end, and

(g) a second longitudinal arm having a first end connected to the second end of the second transverse leg of the block Y-shaped support unit and a second end;

C) a first wheel unit rotatably connected to the second ends of the first support arm, the first connecting link and the first leg of the Y-shaped support unit;

D) a second wheel unit rotatably connected to the second ends of the second support arm, the second connecting link and the second leg of the Y-shaped support unit;

E) a third wheel unit rotatably connected to the second ends of the longitudinal leg of the Y-shaped support unit, the first longitudinal arm of the block Y-shaped support unit and the second longitudinal arm of the block Y-shaped support unit;

F) the seat section and the frame section being collapsible to move between a deployed orientation with the wheel units being located spaced apart from the seat section and a folded orientation with the wheel units located closely adjacent to the seat section with the third wheel unit located between the first and second wheel units.

2. The stroller defined in claim 1 wherein the seat section is formed of flexible material.

3. The stroller defined in claim 2 in which the first end of the seat section is attached to the first and second legs of the block Y-shaped support unit.

5. The stroller defined in claim 1 wherein the wheel units are pivotable between a deployed condition in which the wheel units are oriented to roll over a supporting surface and a stored condition in which the wheel units are oriented at an angle with respect to the deployed condition.

6. The stroller defined in claim 5 wherein the wheel units are pivotable between a deployed condition in which the wheel units are oriented to roll over a supporting surface and a stored condition in which the wheel units are oriented at an angle with respect to the deployed condition.

4. A stroller comprising:

A) a seat unit;

B) a frame unit for supporting the seat unit, the frame unit including two Y-shaped supporting units and links connecting the frame units together in a manner which allows the two frame units to collapse on each other and lie adjacent to the seat unit in a collapsed configuration and to extend into a seat unit supporting orientation in a deployed orientation; and

C) a plurality of wheel units connected to the frame units.
