Abstract
Abstract A drain cover having separable mounting means which is adjustable for operational installation in drain pipes of varying standard sizes. The mounting means comprise resilient fingers having short feet which are releasably engageable in radially spaced stirrups die punched from the drain cover disc. In another preferred embodiment, the drainage openings comprise elongated slots having roll formed tubular sockets depending therefrom and the resilient fingers have pairs of wire feet which are frictionally engageable in said sockets.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
73 words
A drain cover comprising: a disc having drainage openings formed therein; a plurality of separable mounting means associated with the disc for operationally mounting the drain cover on a drain pipe; and connector means on said disc for releasably connecting said mounting means to said disc, said connector means being arranged to provide adjustable selective positioning of said mounting means whereby said drain cover is operationally installable on drain pipes of varying diameters.
Claim 2
Dependent Claim
73 words
A drain cover comprising: a disc having drainage openings formed therein; a plurality of separable mounting means associated with the disc for operationally mounting the drain cover on a drain pipe; and connector means on said disc for releasably connecting said mounting means to said disc, said connector means being arranged to provide adjustable selective positioning of said mounting means whereby said drain cover is operationally installable on drain pipes of varying diameters.
Claim 3
Dependent Claim
24 words
A drain cover according to claim 1 wherein said disc is circular in configuration and said connecter means lie on radii of said disc.
Claim 4
Dependent Claim
24 words
A drain cover according to claim 2 wherein said connector means are integrally formed with said disc and depend from the bottom surface thereof.
Claim 5
Dependent Claim
30 words
A drain cover according to claim 3 wherein said mounting means comprises a plurality of resilient fingers, each of said fingers being releasably engageable with any of said connector means.
Claim 6
Dependent Claim
38 words
A drain cover according to claim 4 wherein said connector means are arranged in regularly spaced relationship along said radii whereby said fingers are selectively engageable in said connector means to define circles of a plurality of diameters.
Claim 7
Dependent Claim
24 words
A drain cover according to claim 5 wherein said connector means comprises a plurality of stirrups die punched from said disc and integral therewith.
Claim 8
Dependent Claim
33 words
A drain cover according to claim 6 wherein each of said fingers comprises an elongated leg and an integral foot substantially perpendicular thereto, said foot being frictionally engageable in any of said stirrups.
Claim 9
Dependent Claim
40 words
A drain cover according to claim 7 wherein said foot comprises an integral protuberance adjacent the free end thereof, said protuberance being releasably snap-fittable into said stirrup and cooperating with the stirrup to prevent inadvertent removal of said leg therefrom.
Claim 10
Dependent Claim
44 words
A drain cover according to claim 5 wherein said drainage openings comprise a plurality of slots lying on radii of said disc and said connector means comprises a plurality of opposed pairs of tubular sockets integrally depending from the marginal edges of said slots.
Claim 11
Dependent Claim
43 words
A drain cover according to claim 9 wherein each of said fingers comprises a bent wire member having an elongated leg and a pair of feet substantially perpendicular to said leg, said feet being frictionally engageable in any of said pairs of sockets.
Claim 12
Dependent Claim
90 words
A drain cover comprising: a circular disc having a plurality of drainage openings formed therein; a plurality of separable resilient mounting fingers associated with said disc for operationally mounting the drain cover on a drain pipe; and a plurality of spaced connector means integrally depending from said disc, said connector means being arranged on opposed radii of said circular disc whereby said fingers are selectively engageable with said connector means to define circles of varying diameters whereby said drain cover is operationally installable on drain pipes of varying inner diameters.
Claim 13
Dependent Claim
90 words
A drain cover comprising: a circular disc having a plurality of drainage openings formed therein; a plurality of separable resilient mounting fingers associated with said disc for operationally mounting the drain cover on a drain pipe; and a plurality of spaced connector means integrally depending from said disc, said connector means being arranged on opposed radii of said circular disc whereby said fingers are selectively engageable with said connector means to define circles of varying diameters whereby said drain cover is operationally installable on drain pipes of varying inner diameters.
Claim 14
Dependent Claim
27 words
A drain cover according to claim 11 wherein said connector means are arranged in regularly spaced relationship on at least four of said radii of said disc.
Claim 15
Dependent Claim
31 words
A drain cover according to claim 12 wherein said connector means comprises a plurality of stirrups punched from said disc and said fingers comprise short feet frictionally engageable in said stirrups.
Claim 16
Dependent Claim
39 words
A drain cover according to claim 12 wherein said drainage openings comprise four elongated slots lying on radii of said disc and said connector means comprises opposed pairs of tubular sockets depending from the marginal edges of said slots.
Claim 17
Dependent Claim
41 words
A drain cover according to claim 14 wherein said drainage openings comprise further four shorter slots lying on other radii of said disc and said connector means comprises pairs of tubular sockets depending from the marginal edges of said shorter slots.
Claim 18
Dependent Claim
38 words
A drain cover according to claim 15 wherein each of said fingers comprises an integral return-bent member having an elongated leg and a pair of short feet substantially perpendicular thereto, said feet being frictionally engageable in said sockets.
