A patient support is configured to support a person in at least a horizontal position. A propulsion device may be coupled to the patient support to facilitate movement of the patient support from one location to another. The propulsion device includes at least one wheel. A deployment mechanism moves the wheel between a storage position and a use position relative to the patient support. The deployment mechanism is motorized. The deployment mechanism uses a toggle force to initiate movement of the wheel from the storage position to the use position.
