Abstract
Abstract A heater traverse mechanism used with an infant care center is disclosed. The traverse mechanism allows the heater that is focused on or about the infant positioned on the infant care center to be moved aside for better access to the infant, yet, as the heater is moved, the traverse mechanism automatically adjusts the heater such that its focus remains on the infant so that even at various points along a locus, the footprint of heat on or about the infant remains relatively constant.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
An infant care unit comprising: a standing frame member; a generally planar infant bed affixed to said standing frame member and adapted to underlie an infant; a heater mounted to said standing frame member above said infant bed and focused to direct heat on or about an infant positioned on said infant bed; mounting means for mounting said heater to said frame member to constrain said heater to be manually moved along a locus while maintaining the focus of said heater on the same location on said infant bed.
Claim 2
Dependent Claim
89 words
An infant care unit comprising: a standing frame member; a generally planar infant bed affixed to said standing frame member and adapted to underlie an infant; a heater mounted to said standing frame member above said infant bed and focused to direct heat on or about an infant positioned on said infant bed; mounting means for mounting said heater to said frame member to constrain said heater to be manually moved along a locus while maintaining the focus of said heater on the same location on said infant bed.
Claim 3
Dependent Claim
31 words
An infant care unit as defined in claim 1 wherein said locus along which said heater is moveable is a radial arc having, as the centerpoint, the position of the infant.
Claim 4
Dependent Claim
44 words
An infant care unit as defined in claim 1 wherein said locus along which said heater is moveable is in a plane generally parallel to the plane of said infant bed and said heater rotates to maintain the focus on or about the infant.
Claim 5
Dependent Claim
24 words
An infant care unit as defined in claim 3 wherein said heater is a linear radiant heater providing a rectangular footprint on the infant.
Claim 6
Dependent Claim
119 words
An infant care unit comprising: a standing frame member; a generally planar infant bed suspended from said frame member and adapted to underlie an infant; a heater mounted to said frame member above said infant bed and adapted to be focused to direct heat on or about an infant positioned on said infant bed; mounting means for said heater to allow said heater to be moved laterally across said infant bed in a plane generally parallel with the plane of said planar infant bed; and said mounting means further adapted to rotate said heater as said heater moves laterally across said infant bed to retain the focus of said heater on the same general location on said infant bed.
Claim 7
Dependent Claim
119 words
An infant care unit comprising: a standing frame member; a generally planar infant bed suspended from said frame member and adapted to underlie an infant; a heater mounted to said frame member above said infant bed and adapted to be focused to direct heat on or about an infant positioned on said infant bed; mounting means for said heater to allow said heater to be moved laterally across said infant bed in a plane generally parallel with the plane of said planar infant bed; and said mounting means further adapted to rotate said heater as said heater moves laterally across said infant bed to retain the focus of said heater on the same general location on said infant bed.
Claim 8
Dependent Claim
43 words
An infant care unit as defined in claim 5 wherein said mounting means comprises a bearing means supported by said frame member on which said heater is mounted, and said mounting means causes said heater to rotate as said heater is moved thereacross.
Claim 9
Dependent Claim
63 words
An infant care unit as defined in claim 6 wherein said mounting means further comprises an inclined track mounted to said frame, and said heater includes an elongated arm depending outwardly therefrom and having a cam at the outward end thereof, said cam being adapted to fit within said inclined track to rotate said heater as said heater moves along said bearing means.
Claim 10
Dependent Claim
24 words
An infant care unit as defined in claim 7 wherein said heater comprises a linear radiant heater providing a rectangular footprint on said infant.
Claim 11
Dependent Claim
17 words
An infant care unit as defined in claim 7 wherein said bearing means comprises a linear bearing.
