Abstract:
An infant seat comprising:a) a shell including a first side with a first side hub having a first hub axis; b) a handle including a first arm with a first arm hub which is substantially coaxially aligned with, and rotatably attached to, the first side hub, wherein one of the first side and arm hubs has first, second, third, and fourth notches, wherein the first and second notches each have an opening facing substantially radially inward toward the first hub axis, wherein the third and fourth notches each have an opening facing substantially radially outward away from the first hub axis, wherein the other of the shell and the handle has a first projection and a second projection, wherein the second projection is rotationally aligned with the third notch when the first projection is rotationally aligned with the first notch, and wherein the second projection is rotationally aligned with the fourth notch when the first projection is rotationally aligned with the second notch; and c) a first spring having a longitudinal axis which is aligned substantially parallel to the first hub axis, wherein the first spring is disposed to simultaneously radially-outwardly bias into engagement the first projection and a rotationally-aligned first notch and radially-inwardly bias into engagement the second projection and a rotationally-aligned third notch, wherein the handle is movable with respect to the shell in a direction substantially perpendicular to the first hub axis to simultaneously radially-inwardly move out of engagement the first projection and the rotationally-aligned first notch and radially-outwardly move out of engagement the second projection and the rotationally-aligned third notch and thereafter the handle is rotatable with respect to the shell about the first hub axis to simultaneously rotationally move the first projection into rotational alignment with the second notch and the second projection into rotational alignment with the fourth notch whereafter the first spring simultaneously radially-outwardly biases into engagement the first projection and the second notch and radially-inwardly biases into engagement the second projection and the fourth notch.
