Abstract
Abstract A stroller carseat apparatus is set forth wherein a carseat includes a scissor-like underlying framework including a pivotally mounted wheel proximate each corner of the framework securable in a first locked upper position to a second lowered extended position. An electrical circuit is included within the framework wherein an illumination source proximate the uppermost portion of the seat is illuminated upon completion of a circuit effected by the locking of the wheels in the second lowered position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
An infant seat stroller apparatus comprising, an infant seat fixedly secured to a first bottom framework, a second bottom framework reciprocatably mounted relative to said first bottom framework and underlying said first bottom framework with a scissor frame mounted within said first and second bottom framework to effect positioning of said second bottom framework relative to said first bottom framework, a rear framework including a handle mounted rearwardly of said infant seat, a plurality of spaced wheel units rotatably mounted to said second bottom framework and rotatable from a retracted first position to a lowered ground engaging second position relative to said second bottom framework, each wheel unit including a rotatable member selectively securable in said first or second positions with a plurality of apertures engageable with a wheel latch button mounted within said second bottom framework and a switch adapted to be in a closed position when the wheel unit is rotated to the lowered second position, and, visual indicator means mounted in said handle operatively associated with the switch of each wheel unit for providing a visual indication only when all of said wheel units are positioned in said lowered second position.
Claim 2
Dependent Claim
194 words
An infant seat stroller apparatus comprising, an infant seat fixedly secured to a first bottom framework, a second bottom framework reciprocatably mounted relative to said first bottom framework and underlying said first bottom framework with a scissor frame mounted within said first and second bottom framework to effect positioning of said second bottom framework relative to said first bottom framework, a rear framework including a handle mounted rearwardly of said infant seat, a plurality of spaced wheel units rotatably mounted to said second bottom framework and rotatable from a retracted first position to a lowered ground engaging second position relative to said second bottom framework, each wheel unit including a rotatable member selectively securable in said first or second positions with a plurality of apertures engageable with a wheel latch button mounted within said second bottom framework and a switch adapted to be in a closed position when the wheel unit is rotated to the lowered second position, and, visual indicator means mounted in said handle operatively associated with the switch of each wheel unit for providing a visual indication only when all of said wheel units are positioned in said lowered second position.
Claim 3
Dependent Claim
73 words
An infant seat stroller apparatus as set forth in claim 1 wherein said plurality of apertures comprise a first aperture operatively associated with said latch button to position said wheel unit in said first position and a second aperture offset relative to said first aperture and operably associated with said latch button to position said wheel unit in said second lowered position, said second aperture having a diameter greater than said first aperture.
Claim 4
Dependent Claim
86 words
An infant seat stroller apparatus as set forth in claim 2 wherein said latch button comprises a latch button resiliently mounted within said second bottom framework and formed with a latch plate mounted within said second bottom framework and including an orthogonally extending button wherein said button comprises a stepped profile with an outwardly positioned first diameter substantially equal to the diameter of said first aperture and a second diameter adjacent said latch plate of a diameter substantially equal to the diameter of said second aperture.
Claim 5
Dependent Claim
47 words
An infant seat stroller apparatus as set forth in claim 3 wherein said switch of each wheel unit includes a plurality of electrical contacts positioned within said second bottom framework and mounted for engagement with said latch plate when said second aperture is aligned with said button.
Claim 6
Dependent Claim
56 words
An infant seat stroller apparatus as set forth in claim 4 wherein said indicator means mounted within said handle comprises an illumination means electrically associated with the switch of each wheel unit whereupon when all of said wheel units are positioned in said second position, an electrical circuit is completed for illumination of said illumination means.
Claim 7
Dependent Claim
32 words
An infant seat stroller apparatus as set forth in claim 5 wherein said handle further includes a battery compartment including at least one battery for supplying electrical energy to said illumination means.
Claim 8
Dependent Claim
19 words
An infant seat stroller apparatus as set forth in claim 6 wherein said handle telescopingly receives said rear framework.
Claim 9
Dependent Claim
51 words
An infant seat stroller apparatus as set forth in claim 7 wherein the handle includes a handle aperture aligned with a frame aperture, and a further latch button and latch plate mounted within said rear framework whereupon depressing of said latch button enables said handle to telescopingly receive said rear framework.
