Abstract
A locking assembly for a wheeled transportation cart, comprising an adjustment member in rotatable engagement with the frame of the wheeled cart. The adjustment member is selectively adjustable between a locked position thereby preventing rolling movement of the wheeled cart, and an unlocked position thereby allowing rolling movement of the wheeled cart. The adjustment member contains a first knee formed by a first bent section in the adjustment member which is engaged between a first locking element and a first locking channel, and a second knee formed by a second bent section in the adjustment member which is engaged between a second locking element and a second locking channel. As the adjustment member rotates between the locked and the unlocked positions, the adjustment member forces the first and second locking elements downward toward a support surface and engages a first and second locking assembly spring means to urge the first and second locking elements into contact with the support surface.
