ABSTRACT:
In a wheel and brake assembly for a wheeled cart, such as a shopping cart or a luggage cart, a horn is mountable to the cart so as to extend downwardly from the cart. A wheel defining a wheel axis and including a hub is journalled to the horn at the hub. A pin projects from the hub but clears the horn when the wheel is rotated. A bracket is mounted pivotably to the horn so as to be pivotable over a limited range, between an inoperative position and an operative position, with a tang projecting axially from the bracket. The tang is arranged to engage the pin so as to brake the wheel against further rotation in one rotational sense, once the bracket has been pivoted to the operative position, if the wheel is rotated by less than one full revolution in the same rotational sense. The pin is arranged to engage the tang so as to pivot the bracket from the operative position, and so as to release the wheel, if the wheel is rotated by less than one full revolution in the opposite rotational sense.
