Car seat stroller system and method

A device for securing and transporting a child, the device comprising:

• a child safety seat including a support frame and an internal harness, the child safety seat further including a padded seat affixed to said support frame, said child safety seat configured to hold and secure a child to said child safety seat;
• a retractable handle fixed to said support frame and configured to transfer loads between said retractable handle and said child safety seat, said retractable handle having a deployed-handle state and a stowed-handle state;
• a plurality of wheels fixed to said child safety seat configured to rollingly translate said child safety seat when towed or pushed via said retractable handle, and at least two of the plurality of wheels further configured to retract relative to said child safety seat, said at least two of the plurality of wheels having a deployed-wheel state and a stowed-wheel state;
• wherein said padded seat includes a seat-bottom and a seat-back;
• wherein said support frame includes a base-member configured to support said seat-bottom, and a back-member configured to support said seat-back, said support frame further configured to retain said seat-bottom and said seat-back at an angle between 85 degrees and 120 degrees relative to each other;
• wherein said base-member has an upper surface and a lower surface, said upper surface configured to receive and support said seat-bottom, said lower surface configured to receive and support said the plurality of wheels;
• wherein said base-member includes at least one cavity configured to house said at least two of the plurality of wheels having said deployed-wheel state and said stowed-wheel state;
• wherein said at least two of the plurality of wheels having said deployed-wheel state and said stowed-wheel state are further configured to lock out, such that said at least two of the plurality of wheels are able to be rolled on a ground surface when in said deployed-wheel state, and to at least partially retract into said at least one cavity when in said stowed-wheel state;
• wherein said each of the at least two of the plurality of wheels having said deployed-wheel state and said stowed-wheel state have a rotational axis of deployment, and each rotational axis of deployment rotates at least 85 degrees between said deployed-wheel state and said stowed-wheel state;
• wherein said at least two of the plurality of wheels having said rotational axis of deployment between said deployed-wheel state and said stowed-wheel state are coupled to a rotator-link such that said at least two of the plurality of wheels are able to rotate in parallel motion with each other when in motion between said deployed-wheel state and said stowed-wheel state;
• wherein each said rotator-link of each said at least two of the plurality of wheels is fixedly-joined with a master-link such that movement of each said rotator-link is simultaneously initiated by activation of said master-link;
• wherein loads transferred between said retractable handle and said child safety seat are transferred via said back-member;
• wherein said back-member is configured to stow at least portions of said retractable handle when said retractable handle is in said stowed-handle state;
• wherein said back-member includes a handle receiver configured to slidably-retain said retractable handle;
• wherein said retractable handle includes a hand grip, a first-extension-arm, and a second-extension-arm, said hand grip having a first-grip-end and a second-grip-end laterally opposite said first-grip-end, said first-extension-arm coupled to said first-grip-end and said second-extension-arm coupled to said second-grip-end together in a U-shape with said first-extension-arm, and said second-extension-arm substantially parallel with each other;
• wherein said hand grip is configured for a user to hold to push, pull, tilt, and maneuver said child safety seat;
• wherein said retractable handle further includes a quick release proximate to the first grip end, the quick release configured to deploy the at least two of the plurality of wheels towards the deployed-wheel state and completing a deployment at the lock out stop upon a first activation of said quick release, the quick release further configured to release said lock out stop and to stow the at least two of the plurality of wheels towards the stowed-wheel state upon a second activation of said quick release;
• wherein said hand grip is at least partially made from non-slip elastomeric materials and is configured to retain gripping properties when exposed to wet, and alternatively humid, environments;
• wherein said first-extension-arm and said second-extension-arm are configured to extend from and retract through a guide proximate to said back-member, the guide including a first-extension-arm bushing and a second-extension-arm bushing;
• wherein said first-extension-arm is coupled with said first-extension-arm-receiver and said second-extension-arm is coupled with said second-extension-arm-receiver such that said retractable handle is able to be raised from said deployed-handle state and alternatively lowered to said stowed-handle state;
• wherein said support frame is at least partially made of durable plastic materials that are able to resist damage when said child safety seat is traversed over rough, and alternatively wet, surfaces;
• wherein said child safety seat is able to be removably-integrated with a standard safety restraint system for a vehicle;
• wherein said seat-bottom and said seat-back are at least partially made of body-supporting materials including padding configured to cushion said child from the support frame, said padding further configured to approximate a body position of said child when restrained in said child safety seat, and a durable cover cloth having UV-resistant properties, said durable cover cloth able to be repeatedly cleaned;
• and
• wherein said internal harness includes a plurality of shoulder straps, a crotch strap, and a safety-buckle, the internal harness configured to couple with the seat-bottom and seat-back.

A method of using the device for securing and transporting a child, the method comprising the steps of:

• installing a device for securing and transporting a child in a vehicle;
• positioning the child in a child safety seat;
• restraining the child in the child safety seat with an internal harness;
• removing the device for securing and transporting a child in a vehicle from the vehicle and placing on the ground;
• pressing a pushbutton configured to deploy at least two of a plurality of wheels to a deployed-wheel state;
• deploying a retractable handle from a stowed-handle state;
• and
• rollingly-translating the child safety seat.
