Brake mechanism for an infant stroller apparatus

摘要

A brake mechanism suitable for use with an infant stroller apparatus includes two wheel supports adapted to affix with two transversally spaced-apart legs of the infant stroller apparatus, two wheels respectively assembled with the two wheel supports about a rotation axis, wherein each of the two wheels includes a hub portion, two latches respectively assembled with the two wheel supports and operable to rotationally lock the two wheels, and a brake actuating assembly including two cam surfaces in sliding contact with the two latches, wherein the two cam surfaces are operable to rotate about the rotation axis to cause displacements of the two latches parallel to the rotation axis to respectively engage and disengage the hub portions of the two wheels.

1. A brake mechanism for use in an infant stroller apparatus, comprising:
two wheel supports adapted to affix with two transversally spaced-apart legs of the infant stroller apparatus; two wheels respectively assembled with the two wheel supports about a rotation axis, wherein each of the two wheels includes a hub portion; two latches respectively assembled with the two wheel supports and operable to rotationally lock the two wheels; and two brake actuators respectively disposed adjacent to the two wheel supports, and a cable having two opposite ends respectively anchored with the two brake actuators, each of the two brake actuators respectively having a cam surface, at least one of the two brake actuators having a ridge that projects along the rotation axis and defines the cam surface associated therewith, the two cam surfaces of the two brake actuators being respectively in sliding contact with the two latches, wherein the two brake actuators are rotatable about the rotation axis to cause displacements of the two latches parallel to the rotation axis to respectively engage and disengage the hub portions of the two wheels, the cable coupling each other the two brake actuators.
