Abstract:
A stroller assembly comprising:a) a stroller frame; b) an axle coupled to the stroller frame; c) a stroller wheel rotatable about the axle, wherein the wheel has a hub portion, and wherein the hub portion includes a radially-aligned hub slot; and d) a brake assembly including: (1) a cam which is non-rotatably attached to the axle and which has a protrusion; and (2) a radially-movable pin which has a longitudinal axis aligned substantially parallel to the axle, which is disposed to follow the cam, and which has a first end which is disposed to radially move into and out from the hub slot, wherein rotation of the cam causes the pin to outwardly follow the protrusion and move radially outward to a first position, wherein counter-rotation of the cam causes the pin to inwardly follow the protrusion and move radially inward to a second position, wherein the first position is one of an engagement position and a disengagement position, wherein the second position is the other of the engagement position and the disengagement position, wherein the engagement position is a position in which the pin is radially engaged in the hub slot to lock the wheel against rotation about the axle, and wherein the disengagement position is a position in which the pin is radially disengaged from the hub slot to allow the wheel to rotate about the axle and wherein the pin is biased towards the cam.
