Abstract

A system to transport infant children usable as an integrated unit or with a universal tower attachment system is provided that includes a base configured to be secured to a portion of an automobile; a chassis releasably coupled to the base; and a shell. The shell includes a frame configured to support an infant; a carrying handle movably coupled to the frame at a hub; a first latch operable to selectively, releasably couple the shell to the chassis; and a second latch adjacent the hub to selectively, releasably couple the shell to the tower attachment system. The shell may be selectively coupled to the chassis or to the tower attachment system.

Claims (27)

1 . A system to transport infant children, comprising:

a base;

a chassis releasably coupled to the base; and

a shell configured to support an infant, comprising:

a carrying handle movably coupled to the shell at a hub;

a first latch operable to selectively, releasably couple the shell to the chassis; and

a second latch adjacent the hub that is selectively releasable;

a release handle, and a cable coupled between the release handle, the first latch and the second latch, wherein the release handle releases both the first latch and the second latch;

wherein the shell may be selectively coupled to the chassis via the first latch, and wherein the second latch is selectively releasable;

wherein the first latch comprises a slider bar having at least one hook extending away from the slider bar, the slider bar being selectively coupled to the cable, and wherein the chassis further comprises at least one fixed catch, and wherein the at least one hook engages the at least one fixed catch to couple the shell to the chassis and wherein the at least one hook is releasable from the at least one catch upon operation of the release handle when the slider bar is coupled to the cable.

2 . The system of claim 1 , wherein the slider bar has a plurality of hooks extending away from the slider bar, and wherein the chassis further comprises a corresponding plurality of catches, and wherein each hook from the plurality of hooks engages a corresponding catch from the plurality of catches to couple the shell to the chassis and wherein the plurality of hooks are releasable from the plurality of catches upon operation of the release handle when the slider bar is coupled to the cable.

3 . The system of claim 2 , wherein the chassis further comprises a pair of front legs, a pair of rear legs, and a bar extending at least partially between the rear legs, and wherein the first latch further comprises a front hook at a distal end of the cable, the front hook being pivotally coupled to the frame of the shell and movable from a closed position where the front hook engages the bar and an open position where the hook is pivoted away from the bar, the front hook being moveable from the closed position to the open position upon operation of the release handle.

4 . The system of claim 3 , further comprising a pin movable within the frame of the shell, the pin moveable from a first position, where the pin engages the cable and the slider bar such that the slider bar moves with the cable, to a second position where the pin is recessed from the cable and the slider bar, such that the slider bar does not move as the cable moves.

5 . The system of claim 4 , wherein the pin engages the bar when the shell and chassis are installed in the base and the pin is moved by the base into the first position, and wherein the pin moves to the second position when the chassis and shell are removed from the base.

6 . An infant child transport assembly, comprising:

a base;

a chassis releasably coupled to the base; and

a shell comprising:

a first latch operable to selectively, releasably couple the shell to the combined unit of the chassis and the base; and

a second latch selectively releasable when the shell is decoupled from the chassis;

a release handle, and a cable coupled between the release handle, the first latch and the second latch, wherein operation of the release handle simultaneously releases both the first latch and the second latch;

wherein the first latch comprises a slider bar having at least one hook extending away from the slider bar, the slider bar being selectively coupled to the cable, and wherein the chassis further comprises at least one fixed catch, and wherein the at least one hook engages the at least one fixed catch to couple the shell to the chassis and wherein the at least one hook is releasable from the at least one catch upon operation of the release handle when the slider bar is coupled to the cable

wherein the shell may be selectively coupled to the chassis.

7 . The assembly of claim 6 , further comprising a carrying handle movably coupled to the shell, wherein the second latch is located at the coupling of the carrying handle and the frame.

8 . The assembly of claim 7 , wherein the second latch comprises a hook rotatably coupled to the frame of the shell adjacent the coupling of the carrying handle and the frame.

9 . The assembly of claim 8 , wherein the hook is spring-biased to a closed position.

10 . The assembly of claim 9 , wherein the first latch is operable only when the shell and chassis are coupled to the base.
