The wheel lock assembly includes a housing that is either integrally formed on a frame, or provided as a separate component for adjustable mounting on the frame. The housing includes a circular opening that receives a disk that rotates relative to the housing. A handle is either integrally formed with the disk or, alternately, secured to the disk as a separate component, to selectively rotate the disk relative to the housing. An actuating shoe is pivotally mounted to the housing and includes a cam opening that cooperates with a pin secured to the disk at a position spaced from the central axis of rotation of the disk to convert the rotational movement of the handle and disk into translational movement of the shoe. This allows the shoe to be moved between locked and unlocked positions relative to the wheel of a wheeled apparatus such as a wheelchair, patient transport, stroller, or the like. The cam opening may also adopt alternative configurations to vary the travel of the shoe as desired.
