Abstract
An ambulance stretcher having a wheeled base (11) supported by foldable leg assemblies (16, 17). Castors (313, 393) are provided on the leg assemblies for providing improved mobility of the stretcher. The front castors (313) are selectively locked by a locking mechanism (30) to either allow the castors to swivel or roll in a single direction. The locking mechanism is accessible on both sides of the stretcher. Activation of the locking mechanism on either side of the frame selectively locks or unlocks both front castors.
