ABSTRACT:
A braked twin-wheel caster assembly consists of five components--a body, two indentical wheels, a metal wheel spindle and a locking lever. A molded brake lever, rockable between a wheel-locking position and an unlocking position in which the wheels are free to turn, has an intermediate mounting portion which pivots in a bearing recess in the moulded body. The bearing recess is disposed towards the trailing end of the body, and it is open at an outer aperture and also at an inner aperture. An outer end portion of the locking lever projects through the outer aperture to provide an operating member for external operation. An inner end portion of the locking lever projects from said inner aperture to provide a locking member for engagement with the caster wheels. The intermediate portion of the locking lever is molded so that it can be resiliently compressed sufficiently for it to be inserted into the bearing recess through the outer aperture.
