Abstract
Abstract A carrier apparatus for transporting infants in a seated position is comprised of a framework equipped with four wheels, and a seat embraced by the framework. The wheels are adapted to be deployed for rolling support of the apparatus whereby the apparatus functions as a stroller. The wheels can also be moved to raised positions beneath the seat, whereby the apparatus functions as a automobile safety restraint seat. In the restraint seat mode of function, the apparatus is held to the automobile seat by a telescopically descendable pushing handle, and an opposed anchoring bar disposed at the bottom rear of the framework.

Claim 1
Independent Claim
343 words
Apparatus for transporting infants in a seated position comprising: (a) a rigid lightweight framework having spaced apart side portions, a back portion, a front portion, and a bottom portion, said portions defining an interior seating region, (b) a pushing handle of generally U-shaped configuration having opposed elongated side members which telescopically engage the side portions of the framework to permit elevational adjustment of said handle, hook-like portions disposed at the upper extremities of the side members and having downwardly directed extremities, and a horizontally oriented gripping bas extending between said extremities of said hook-like portions, (c) a seat supported by said framework within said seating region and comprised of a substantially horizontally disposed lower portion and an upright backrest portion disposed at the rear of said lower portion, (d) a horizontally oriented anchoring bar associated with the bottom and back portions of said framework, (e) a pair of forward wheels mounted upon first bracket means pivotably attached to said framework for rotation about a transverse axis to permit said forward wheels to be swung rearwardly from a forward operational position to a stored position beneath said seat, (f) first clip means for releasably retaining said forward wheels, with the rotational axis of the wheels extending parallel to the longitudinal axis of the framework, when said first bracket means with said forward wheels are secured in their stored position, (g) a pair of rear wheels mounted upon an axle secured to second bracket means pivotably attached to said framework for rotation about a transverse axis manner to permit said rear wheels to be swung forwardly from a rearward operational position to a stored position beneath said seat, and (h) second clip means for releasably retaining said axle when said second bracket means with said rear wheels are secured in their stored position, (i) whereby, when both pairs of wheels are in their operational positions, the apparatus functions as a stroller, and when said wheels are in their stored positions, the apparatus is adapted to function as a restraint seat for use in an automobile.

Apparatus for transporting infants in a seated position comprising: (a) a rigid lightweight framework having spaced apart side portions, a back portion, a front portion, and a bottom portion, said portions defining an interior seating region, (b) a pushing handle of generally U-shaped configuration having opposed elongated side members which telescopically engage the side portions of the framework to permit elevational adjustment of said handle, hook-like portions disposed at the upper extremities of the side members and having downwardly directed extremities, and a horizontally oriented gripping bas extending between said extremities of said hook-like portions, (c) a seat supported by said framework within said seating region and comprised of a substantially horizontally disposed lower portion and an upright backrest portion disposed at the rear of said lower portion, (d) a horizontally oriented anchoring bar associated with the bottom and back portions of said framework, (e) a pair of forward wheels mounted upon first bracket means pivotably attached to said framework for rotation about a transverse axis to permit said forward wheels to be swung rearwardly from a forward operational position to a stored position beneath said seat, (f) first clip means for releasably retaining said forward wheels, with the rotational axis of the wheels extending parallel to the longitudinal axis of the framework, when said first bracket means with said forward wheels are secured in their stored position, (g) a pair of rear wheels mounted upon an axle secured to second bracket means pivotably attached to said framework for rotation about a transverse axis manner to permit said rear wheels to be swung forwardly from a rearward operational position to a stored position beneath said seat, and (h) second clip means for releasably retaining said axle when said second bracket means with said rear wheels are secured in their stored position, (i) whereby, when both pairs of wheels are in their operational positions, the apparatus functions as a stroller, and when said wheels are in their stored positions, the apparatus is adapted to function as a restraint seat for use in an automobile.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1 wherein said framework is fabricated of tubular metal.
Claim 4
Dependent Claim
26 words
The apparatus of claim 2 wherein said pushing handle is an integral piece of tubular metal suitably bent to form said hook-like portions and gripping bar.
Claim 5
Dependent Claim
17 words
The apparatus of claim 1 wherein said forward wheels are of caster-type capable of omnidirectional rolling movement.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1 wherein said rear wheels are constrained to rolling movement in fixed parallel vertical planes outwardly spaced from the side portions of the frame.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1 wherein said forward wheels are spaced closer together than said rear wheels.
Claim 8
Dependent Claim
36 words
The apparatus of claim 1 wherein when said forward and rear wheels are in said operational position, further upward pivotal movement is prevented by abutment of said first bracket means and said axle with said framework.
Claim 9
Dependent Claim
30 words
The apparatus of claim 1 wherein said forward and rear wheels are at a higher elevation with respect to the framework in their stored positions than in their operational positions.
