Abstract
Abstract A pair of spring loaded cylinders each supporting an upwardly projecting post mounted in a drain. A strainer is attached to the drain with the posts porjecting upwards through holes in the strainer. A disposable insert, having a hooked material such as VELCRO sheet on its lower surface, is mounted on a distal end of the posts. Foot pressure on a cover plate mounted on a top surface of the insert forces the VELCRO to contact the strainer and remove all impinged hair and debris.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
143 words
A tub drain device comprising: at least one spring loaded cylinder for mounting in a drain, a hollow cylindrical post projecting upwardly from an associated cylinder when not under stress, a strainer fixedly mounted over the drain, the post projecting upwardly through an associated hole in the strainer, a disposable insert having a top and bottom surface mounted on a portion of the post distal from the cylinder and spaced apart from the strainer by the post projecting from the spring loaded cylinder in a resting mode, the insert engaging a top surface of the strainer in an actuated mode when the post is depressed against the spring loaded cylinder, said disposable insert including a water impermeable hair and dirt pick up element attached to the bottom surface thereof, and a cover plate removably attached to the top surface of the disposable insert.
Claim 2
Dependent Claim
143 words
A tub drain device comprising: at least one spring loaded cylinder for mounting in a drain, a hollow cylindrical post projecting upwardly from an associated cylinder when not under stress, a strainer fixedly mounted over the drain, the post projecting upwardly through an associated hole in the strainer, a disposable insert having a top and bottom surface mounted on a portion of the post distal from the cylinder and spaced apart from the strainer by the post projecting from the spring loaded cylinder in a resting mode, the insert engaging a top surface of the strainer in an actuated mode when the post is depressed against the spring loaded cylinder, said disposable insert including a water impermeable hair and dirt pick up element attached to the bottom surface thereof, and a cover plate removably attached to the top surface of the disposable insert.
Claim 3
Dependent Claim
25 words
A tub drain device according to claim 1 wherein at least one rivet is mounted on the cover plate, and passes through the disposable insert.
Claim 4
Dependent Claim
23 words
A tub drain device according to claim 2 wherein two rivets are mounted on the cover plate and each fits within associated post.
Claim 5
Dependent Claim
21 words
A tub drain device according to claim 1 wherein a ring is mounted on a top surface of the cover plate.
Claim 6
Dependent Claim
22 words
A tub drain device according to claim 1 wherein a hooked material is attached to the top surface of the disposable insert.
Claim 7
Dependent Claim
26 words
A tub drain device according to claim 1 wherein the pickup element is a sheet of hooked material conforming to the shape of the bottom surface.
Claim 8
Independent Claim
107 words
A device that retrieves hiar accumulated atop a strainer for a drain, comprising: a disposable insert member having a top surface and a bottom surface; a hair and dirt pick up means secured to said bottom surface; said insert member having a first position in vertically spaced relation to said strainer and a second position where the hair and dirt pick up means is in contacting relation to said strainer and hence in pick up engagement relation to hair and dirt atop said strainer; and biasing means maintaining said insert member in said first position until driven into said second position by an externally imparted downward force.
Claim 9
Independent Claim
107 words
A device that retrieves hiar accumulated atop a strainer for a drain, comprising: a disposable insert member having a top surface and a bottom surface; a hair and dirt pick up means secured to said bottom surface; said insert member having a first position in vertically spaced relation to said strainer and a second position where the hair and dirt pick up means is in contacting relation to said strainer and hence in pick up engagement relation to hair and dirt atop said strainer; and biasing means maintaining said insert member in said first position until driven into said second position by an externally imparted downward force.
Claim 10
Dependent Claim
57 words
The device of claim 7, wherein said biasing means includes a cylinder member, and wherein a bias element is disposed within said cylinder member, and wherein said biasing means further includes a hollow post member that surmounts said bias element and which is slidably received into said cylinder member when displaced downwardly by an externally imparted force.
Claim 11
Dependent Claim
21 words
The device of claim 8, further comprising a cover plate member secured in overlying relation to said insert member top surface.
Claim 12
Dependent Claim
146 words
The device of claim 9, further comprising a rivet member having a top end secured to said cover plate member and a bottom portion slidably received within said hollow post member whereby said rivet member abuttingly engages a bottom wall of said hollow post member and displaces said bottom wall and hence said hollow post member downwardly when said cover plate member is driven downwardly by said externally imparted force, said cylinder member having a height sufficient to receive a substantial extent of said hollow post member so that said hair and dirt pick up means on the bottom surface of said insert member operatively engages hair and dirt atop said strainer when said rivet member abuts said hollow post member bottom wall and drives said post member into said cylinder member responsive to application of said externally imparted downward force upon said cover plate member.
