Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A retainer for fastening a cross-over pipe to an air conditioner condenser assembly having parallel, spaced apart, laterally extending refrigerant tubes in heat exchange relationship to longitudinally spaced apart cooling fins, said retainer comprising a first longitudinally extending body portion providing two spaced apart, internally directed, opposed C-clamp portions adapted to engage a pair of refrigerant tubes therebetween, a second longitudinally extending body portion forming a pair of opposed concave pipe jaws adapted to engage and retain therebetween the cross-over pipe, and a laterally extending flange formed integral with said first body portion and said second body portion and intermediate therebetween and wherein said first body portion has a relief slot extending to said laterally extending flange between said opposed C-clamp portions and wherein said second body portion has a relief slot extending to said laterally extending flange between said opposed concave pipe jaws.
Claim 2
Dependent Claim
144 words
A retainer for fastening a cross-over pipe to an air conditioner condenser assembly having parallel, spaced apart, laterally extending refrigerant tubes in heat exchange relationship to longitudinally spaced apart cooling fins, said retainer comprising a first longitudinally extending body portion providing two spaced apart, internally directed, opposed C-clamp portions adapted to engage a pair of refrigerant tubes therebetween, a second longitudinally extending body portion forming a pair of opposed concave pipe jaws adapted to engage and retain therebetween the cross-over pipe, and a laterally extending flange formed integral with said first body portion and said second body portion and intermediate therebetween and wherein said first body portion has a relief slot extending to said laterally extending flange between said opposed C-clamp portions and wherein said second body portion has a relief slot extending to said laterally extending flange between said opposed concave pipe jaws.
Claim 3
Dependent Claim
114 words
A unitary molded plastic pipe retainer adapted to engage a pair of laterally extending spaced apart refrigerant tubes of an air conditioner condenser assembly between longitudinally extending spaced apart cooling fins connected in heat exchange relation to said refrigerant tubes and to support a cross-over tube, comprising a laterally extending spacer flange, two spaced apart and opposed C-clamp portions integral with said flange and extending longitudinally from one side thereof for engagement with a pair of the refrigerant tubes and a pair of opposed concave pipe jaws adapted to engage and retain therebetween the cross-over tube, said concave pipe jaws extending longitudinally from the opposite side of said flange from said opposed C-clamp portions.
Claim 4
Dependent Claim
114 words
A unitary molded plastic pipe retainer adapted to engage a pair of laterally extending spaced apart refrigerant tubes of an air conditioner condenser assembly between longitudinally extending spaced apart cooling fins connected in heat exchange relation to said refrigerant tubes and to support a cross-over tube, comprising a laterally extending spacer flange, two spaced apart and opposed C-clamp portions integral with said flange and extending longitudinally from one side thereof for engagement with a pair of the refrigerant tubes and a pair of opposed concave pipe jaws adapted to engage and retain therebetween the cross-over tube, said concave pipe jaws extending longitudinally from the opposite side of said flange from said opposed C-clamp portions.
