Carseat and stroller with folding linkage system
First Claim
1. An apparatus convertible between an infant carseat and stroller, comprising:
- a seat shell configured to hold an infant;
a coupling knee rotatingly coupled to said seat shell;
at least one front wheel pivotally coupled to said knee so that said front wheel pivots relative to said seat shell when said knee rotates;
at least one rear wheel pivotally coupled to said knee so that said rear wheel pivots relative to said seat shell when said knee rotates;
a stroller handle coupled to said knee, said stroller handle moveable between a first position wherein said stroller handle is extended outwardly from said seat shell and a second position wherein said stroller handle is retracted within said seat shell; and
a releasable locking mechanism operably coupled to said stroller handle and said knee, said locking mechanism operable to selectively prevent rotation of said knee; and
a drive link having a first end pivotally coupled to said knee and a second end pivotally coupled to said stroller handle, said drive link coupling said stroller handle to said knee to move said stroller handle between said first and second positions as said knee rotates, wherein as said knee rotates, said stroller handle moves between said first and second positions and said front and said rear wheels pivot relative to said seat shell to allow said front and rear wheels to move between a retracted position usable as a carseat and an extended position usable as a stroller.

Abstract
A combination stroller and carseat is provided that allows the stroller to be conveniently converted into a carseat and infant carrier device. The device has a seat shell configured to hold an infant and a coupling knee rotatingly coupled to the seat shell. At least one front wheel is pivotally coupled to the knee so that the front wheel pivots relative to the seat when the knee rotates. Further, at least one rear wheel is pivotally coupled to the knee so that the rear wheel pivots relative to the seat when the knee rotates. A handle is coupled to the knee that is moveable between a first position wherein the handle is extended outwardly from the seat and a second position wherein the handle is retracted within the seat. A releasable locking mechanism is operably coupled to the handle and the knee that is operable to allow movement of the knee. As the knee rotates, the handle moves between the first and second positions and the front and rear wheels pivot relative to the seat to allow the front and rear wheels to move between a retracted position and an extended position.

at least one handle guide rigidly secured to said seat shell, said handle guide having a hole therethrough that slidingly accommodates said stroller handle, said handle guide further having an elongated locking ramp cavity and a locking pin cavity;
a locking ramp disposed within said ramp cavity, said ramp being shorter than said ramp cavity to allow said ramp to travel within said ramp cavity, said ramp having an angled slot therein; and
a locking pin disposed within said angled slot, wherein said stroller handle has a pair of lock holes therein, said locking pin selectively disposed in one of said lock holes, wherein said actuator button is coupled to said locking ramp so that depressing said actuator button operates to move said locking ramp within said ramp cavity, and wherein as said locking ramp moves, said locking pin is moved upwardly by said angled slot, removing said locking pin from said lock hole, allowing said stroller handle to move within said guide.
