ABSTRACT:
An emergency cot for transporting patients and the like includes a basic patient supporting frame structure of conventional type having supporting wheel structure mounted on a wheel carriage which is connected to the frame support of the cot by suitably collapsing linkage to permit the wheels to be collapsed against the cot with an overall height of approximately one foot, or dropped away from the cot so as to support same at approximately waist level of the attendants using same to transport the patient. An important feature of this device is in spring biased mechanism which may be suitably energized by an attendant operating a pull cable either side of the cot structure to compress dual springs and latch same in compressed position. Then upon release of a wheel carriage latch mechanism, the compressed springs will automatically raise the wheels to the collapsed position. Thus, the attendants transporting a patient need not lower the cot to collapse the wheels, but they merely release the latch mechanism and the wheels will automatically be collapsed due to the biasing of the compressed springs of this mechanism. A further actuation mechanism de-latches the compression spring mechanism upon termination of the collapse cycle so that the carriage may again be operated for free fall of same when the latch mechanism is again released. Dampening structure of both hydraulic and pneumatic type also is provided to slow the rate of carriage collapse.
