Abstract:
1. A patient lift support frame assembly, comprising: a patient-lift-carrying member, and first and second support members for carrying said patient-lift-carrying member, the support members being configured to bear on a floor and support the patient-lift-carrying member above the floor; the first support member comprising a first support element and a second support element slidably engaged with one another such that the length of the first support member is adjusted as the first and second support elements slide relative to each other, one of the first and second support elements being positioned as an upper element of the first support member when the patient lift support frame is assembled, and the other of the first and second support elements being positioned as a lower element when the patient lift support frame is assembled; a driven gear associated with the first support element; a drive gear actuator movably coupled to the second support element and positioned in meshing engagement with the driven gear such that when the actuator is moved, the first and second support elements are urged to slide relative to one another; a lock, movably coupled to the second support element, and engaged with the driven gear, the lock being biased so as to lock against the driven gear to prevent the first and second support elements from sliding so as to shorten the first support member, but configured to permit the first and second support elements to slide so as lengthen the first support member, the lock including an actuator configured to permit the selective unlocking of the lock; a ceiling bearing element, and a spring member, the spring member being fixed to the upper element, the ceiling bearing element being movably mounted to the spring element such that when the ceiling bearing element is pushed against the ceiling, the first support member can move relative to the ceiling bearing element with the ceiling bearing element continuing to bear on the ceiling.
