Stroller with retaining mechanism

1. A transportation system comprising:

a stroller including:

a frame;

a set of wheels coupled to said frame;

a handlebar shaped and located to be gripped by an operator such that said operator can roll said stroller in the desired direction; and

a retaining mechanism; and

an infant carrier shaped to receive an infant therein, said infant carrier being shaped to be selectively mounted to said frame, said retaining mechanism being repositionable responsive to movement of said infant carrier between a retaining position and a loading position such that upward movement of said infant carrier is operative to engage said retaining mechanism and mount said infant carrier to said frame;

wherein said retaining mechanism is biased into said retaining position;

wherein said retaining mechanism is configured such that locating said infant carrier on said frame causes said retaining mechanism to move from said retaining position to said loading position as said infant carrier is located on said frame;

wherein said retaining mechanism returns to said retaining position after said infant carrier is located on said frame; and

wherein said infant carrier can be lifted off of said frame while said retaining mechanism is located in said retaining position without moving said retaining mechanism from said retaining position to said loading position.

2. The system of claim 1 wherein said retaining mechanism is configured such that locating said infant carrier on said frame causes said infant carrier to contact said retaining mechanism to cause said retaining mechanism to move to said retaining position.

3. The system of claim 1 further including a connecting structure extending between said handlebar and said frame, and wherein said retaining structure is located on or adjacent to said connecting structure.

4. The system of claim 3 wherein said connecting structure includes a pair of generally parallel members extending generally upwardly from said frame.

5. The system of claim 1 wherein said infant carrier includes a rear portion that is located adjacent to said retaining mechanism when said infant carrier is located on said frame, and wherein said retaining mechanism is shaped and located to block significant vertical movement of said rear portion of said infant carrier when said infant carrier is located on said frame and said retaining mechanism is in said retaining position.

6. The system of claim 5 wherein said retaining mechanism includes at least two pivotable clips, each clip being pivotable between a retaining position and a loading position and arranged such that the horizontal distance between each clip is greater when said clips are located in their loading positions than when said clips are located in their retaining positions.

7. The system of claim 6 wherein each clip can pivot from said retaining position to said loading position when said infant carrier is lowered onto said frame, and wherein each clip is generally blocked from pivoting from said retaining position to said loading position when said infant carrier is located on said frame.

8. The system of claim 7 wherein each clip is independently pivotable and is biased into the retaining position.

9. The system of claim 5 wherein said retaining mechanism includes at least one pivotable clip.

10. The system of claim 1 wherein when said retaining mechanism is in said loading position said infant carrier can be lowered onto said frame, and wherein when said retaining mechanism is in said retaining position and said infant carrier is located on said frame said retaining mechanism blocks significant vertical movement of at least a portion of said infant carrier.

11. The system of claim 1 further including a locking mechanism located at least partially on at least one of said stroller or said infant carrier for securing said infant carrier and said stroller together, said locking mechanism being spaced apart from said retaining mechanism.

12. The system of claim 1 wherein said retaining mechanism is configured such that locating said infant carrier on said frame causes said retaining mechanism to move to said retaining position.

13. The system of claim 1 wherein said frame includes a retaining bar located generally in front of a seating area of said stroller, and wherein said retaining mechanism is located generally rearwardly of said retaining bar.

14. The system of claim 1 wherein said retaining mechanism is located generally between a rear edge of said frame and said handlebar.
