Abstract
Abstract The invention concerns, for combination with a corner defined by an upright wall, and a generally horizontal surface as defined by a bath tub or the like, and cured mastic applied to said corner, the following: (a) a longitudinally elongated, plastic strip, which is generally crescent shaped in cross section, the strip having terminal edges defined by laterally spaced lips adapted to be supported adjacent the wall and the surface so that the strip confines the mastic in the corner in strip installed position, (b) the mastic in cured state being incompletely rigid, (c) and barb structure integral with the strip and projecting therefrom into the mastic, which in cured state anchors the barb means to retain the strip in said installed position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
177 words
The combination with a corner defined by an upright wall, and a generally horizontal surface as defined by a bath tub or the like, and cured mastic applied to said corner, (a) a longitudinally elongated, plastic strip, which is generally crescent shaped in cross section, the strip having terminal edges defined by laterally spaced lips supported adjacent said wall and said surface so that the strip confines the mastic in said corner in strip installed position, (b) the mastic in cured state being incompletely rigid, (c) and barb means integral with the strip and projecting therefrom into the mastic, which in said cured state anchors the barb means to retain the strip in said installed position, (d) said strip having geater thickness medially between said lips than at said lips, whereby the lips support said strip for flexing toward the corner, said mastic being resilient in cured state, and tensioning said barb means to urge the strip toward said corner, with said lips resiliently engaging said wall and surface, the mastic engaging the strip proximate both lips.
Claim 2
Dependent Claim
177 words
The combination with a corner defined by an upright wall, and a generally horizontal surface as defined by a bath tub or the like, and cured mastic applied to said corner, (a) a longitudinally elongated, plastic strip, which is generally crescent shaped in cross section, the strip having terminal edges defined by laterally spaced lips supported adjacent said wall and said surface so that the strip confines the mastic in said corner in strip installed position, (b) the mastic in cured state being incompletely rigid, (c) and barb means integral with the strip and projecting therefrom into the mastic, which in said cured state anchors the barb means to retain the strip in said installed position, (d) said strip having geater thickness medially between said lips than at said lips, whereby the lips support said strip for flexing toward the corner, said mastic being resilient in cured state, and tensioning said barb means to urge the strip toward said corner, with said lips resiliently engaging said wall and surface, the mastic engaging the strip proximate both lips.
Claim 3
Dependent Claim
30 words
The combination of claim 1 wherein said strip includes at least one integral, longitudinally extending projection on which said barb means is formed, the projection everywhere spaced from said lips.
Claim 4
Dependent Claim
22 words
The combination of claim 1 wherein said barb means defines a barbed tip spaced from the strip, the tip being longitudinally elongated.
Claim 5
Dependent Claim
16 words
The combination of claim 2 wherein said projection and barb means extend generally toward said corner.
Claim 6
Dependent Claim
34 words
The combination of claim 1 wherein said strip includes at least two integral, longitudinally extending, spaced apart projections on each of which said barb means is formed, the projections everywhere spaced from said lips.
Claim 7
Dependent Claim
12 words
the combination of claim 1 wherein said mastic consists of silicone putty.
Claim 8
Dependent Claim
24 words
The combination of one of claims 2 and 5 wherein said mastic consists of resilient, silicone putty, into which said barb means fully penetrates.
Claim 9

18 words
The combination of claim 1 said strip lips have substantially flat surfaces presented toward said wall and surface.
Claim 10
Dependent Claim
32 words
The combination of claim 1 wherein the strip consists of PVC and is twistable and warpable, and flexed toward the mastic after relative and slight shrinkage of the latter toward the corner.
Claim 11
Dependent Claim
22 words
The combination of claim 2 wherein there are three of said projections, which are integral with a thickness portion of the strip.
Claim 12
Dependent Claim
33 words
The combination of claim 1 including pressure senstive tape between one lip and said wall, and between the other lip and said surface, and via which the lips are attached to said wall.
Claim 13
Dependent Claim
15 words
The combination of claim 2 wherein said projection extends beneath said wall, at said corner.
Claim 14
Dependent Claim
