Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
A unitized mounting device securing electrical components of a luminaire such as a ballast, a starter and a capacitor in desired positions in a luminaire housing comprising a central plate adapted to be mounted to the luminaire housing means connected to said central plate securing a capacitor in place and into contact with an inner wall of said housing, means connected to said central plate suspending a starter in place in mid air and means connected to said central plate securing a ballast in place and into contact with said inner wall of said housing.
Claim 2
Dependent Claim
95 words
A unitized mounting device securing electrical components of a luminaire such as a ballast, a starter and a capacitor in desired positions in a luminaire housing comprising a central plate adapted to be mounted to the luminaire housing means connected to said central plate securing a capacitor in place and into contact with an inner wall of said housing, means connected to said central plate suspending a starter in place in mid air and means connected to said central plate securing a ballast in place and into contact with said inner wall of said housing.
Claim 3
Dependent Claim
26 words
A unitized mounting device as defined in claim 1 wherein no more than three fasteners are used to mount the unitized mounting device to said housing.
Claim 4
Dependent Claim
33 words
A unitized mounting device as defined in claim 1 wherein said means securing a capacitor in place and into contact with an inner wall of said housing is welded to said central plate.
Claim 5
Dependent Claim
30 words
A unitized mounting device as defined in claim 3 wherein said means suspending a starter in place in mid air includes spring-like means holding said starter in a desired position.
Claim 6
Dependent Claim
59 words
A unitized mounting device as defined in claim 3 wherein said means securing said ballast in place and into contact with said inner wall is detachable from said central plate in order that when different sized ballasts are used different means securing the ballast in place and into contact with said inner wall of said housing may be used.
Claim 7
Dependent Claim
39 words
A unitized mounting device as defined in claim 5 wherein said means securing said ballast in place and into contact with said inner wall has a slot formed therein for receiving a fastener to connect it to said housing.
Claim 8
Dependent Claim
39 words
A unitized mounting device as defined in claim 6 wherein said means securing a capacitor in place and into contact with said inner wall of said housing includes a spring-like member which biases the capacitor toward said inner wall.
Claim 9
Dependent Claim
42 words
A unitized mounting device as defined in claim 7 wherein said unitized mounting device is adapted to be mounted on said housing in such a manner as to have said housing serve as a heat sink for said capacitor and said ballast.
