Brake mechanism for an infant stroller apparatus

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
• a brake actuating assembly including two cam surfaces in sliding contact with the two latches, wherein the brake actuating assembly includes:
• two brake actuators respectively disposed adjacent to the two wheel supports, each of the two brake actuators having a cam surface, the two cam surfaces of the two brake actuators being 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;
• a linkage extending transversally and connected with the two brake actuators, the linkage including a cable having two opposite ends respectively anchored with the two brake actuators, the connection of the linkage enabling the two brake actuators to rotate in unison;
• and
• a spring assembled around a portion of the cable adjacent to one of the two ends of the cable, the spring being respectively connected with the brake actuator and the wheel support associated therewith.

• two brake actuators respectively disposed adjacent to the two wheel supports and respectively affixed with two opposite ends of a transversal linkage, each of the two brake actuators including an actuating element formed with an annular ring, the annular ring having a contact surface that faces one hub portion and is disposed around the rotation axis, and a recess formed in the contact surface, the annular rings of the two brake actuators being respectively in sliding contact with the two latches;
• wherein the two brake actuators are rotatable in unison 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 two latches when positioned in the recesses of the two brake actuators being disengaged from the hub portions, and the two latches when contacting with the contact surfaces of the two brake actuators being engaged with the hub portions.
