<p>An infant care apparatus that has a canopy (12) that can be moved vertically with respect to an infant pedestal (14) on which the infant is positioned. In the preferred embodiment, the canopy contains a radiant heater (38) that can be moved from a lower position enclosing the infant in an infant compartment to an upper position where the infant compartment is open. The canopy (12) is affixed to a movable frame member (34) that is, in turn, movably mounted on a stationary frame member (32). A constant force spring or springs (42) are used to interconnect between the stationary frame member (32) and the movable frame member (34) and the springs are designed to achieve a counterbalancing of the canopy (12) and associated components such that the weight of such canopy and components is neutralized. Thus, a standard, inexpensive motor (54) can be used to raise and lower the canopy (12) without complex synchronization between two motors and yet the unit moves smoothly and without misalignment. In addition, two sets of stationary (32) and movable (34) frame members can be used and the motor (54) and its lifting mechanism may be located in only one of the sets of frame members (32, 34) without creating a misalignment of the frame members as the canopy (12) is raised and lowered. <IMAGE></p> |
