ABSTRACT:
Presently described are several alternate embodiments for shield devices to enclose and thereby prevent entrapment of objects in the interior space formed by elements of an adjustable bed in the raised position. Such shield devices may include physical barriers. In other embodiments, the shield may include optical sensors that provide rapid detection of intruding objects, thereby activating controls that preclude the further movement of the adjustable bed mechanism. In a further embodiment, an operative shield may be provided by means of a specially adapted controller configured such that only an authorized user can cause the adjustable bed to operate, thereby preventing the possibility that the bed could be operated while any object has intruded into the interior space.
