ABSTRACT:
A caster wherein the inverted U-shaped frame carries a wheel and is turnable relative to a support about a substantially vertical axis when the wheel rests on a horizontal supporting surface. The web of the frame overlies a braking pedal which can be pivoted to and from an operative position in which it blocks rotation of the wheel relative to the frame and/or blocks angular movements of the frame relative to the support. A leaf spring of the braking lever biases the latter to its inoperative position, and a pedal which is pivotably mounted in the frame can be depressed to pivot the lever to and to releasably hold the lever in the operative position. The pedal can be pivoted in a direction to permit the leaf spring to return the lever to inoperative position in response to depression of a substantially vertically reciprocable pusher which is mounted in the web of the frame.
