Abstract

A floor drain having a drainage gutter and a detachable cover that is firmly attached to the floor drain and configured to hold a tile that complements or accents the tile in the shower, the surrounding floor, or the floor plane.

Claims

1. A floor drain with a detachable cover comprising:

a. a generally rectangular base having a downwardly sloping bottom and four sides extending vertically upward from said bottom'"'"'s outer edges, said bottom having;

(1) a drainage hole positioned in its center with a cylindrical side extending vertically downward from said hole'"'"'s edges,

(2) four truncated cylindrical support post footings positioned near each of said bottom'"'"'s outer corners and having threaded holes centered and countersunk therein,

(3) four cylindrical support posts equal in diameter to said support post footings, said support posts having threaded holes equal in diameter to that of said holes in said footings, centered and countersunk therein, with said support post firmly attached to said support post footing by a screw; and

b. a generally rectangular detachable insert with smaller linear dimensions than those of said base and having a horizontal bottom that rests upon said support posts so as to create a horizontal channel between said bottom of said base and said bottom of said detachable insert, said bottom of said detachable insert having four sides extending vertically upward from said bottom'"'"'s outer edges so as to be equal in height to said sides of said base and creating a vertical channel between said sides of said base and said sides of said detachable insert, said bottom having;

(1) one or more drain holes positioned at or near the center of said bottom,

(2) four cylindrically-segmented securing wedges extending vertically downward from said bottom'"'"'s underside, each of said securing wedges having a concave inner surface facing said bottom'"'"'s outer corners, a diameter equal to that of said support posts, and positioned on said underside so that said inner surface of each securing wedge is directly over said side of a corresponding support post thereby creating surface-to-surface contact between said four inner surfaces and said four sides of said support posts when said detachable insert is inserted into said base.

2. The floor drain according to claim 1 wherein said support post footing and said base bottom are uniformly cast.

3. The floor drain according to claim 1 wherein said support post footing and said base bottom are cast separately whereby said support post footing has an angled bottom surface with a slope equal to that of said base bottom thereby ensuring that said support post'"'"'s top surface is horizontal.

4. The floor drain according to claim 1 further comprising two solid truncated pyramidal metal tabs extending perpendicularly from said cylindrical side, said tabs capable of receiving set screws to attach said drain to a waste water pipe thereby permitting removal of said base from said waste water pipe in the event of damage to said base.

5. The floor drain according to claim 1 further comprising one or more horizontal grooves each separately cast or gouged into and centered on one or more inner surfaces of one or more of said detachable insert'"'"'s sides.

6. The floor drain according to claim 4 wherein said support post footing and said base bottom are uniformly cast.

7. The floor drain according to claim 4 wherein said support post footing and said base bottom are cast separately whereby said support post footing has an angled bottom surface with a slope equal to that of said base bottom thereby ensuring that said support post'"'"'s top surface is horizontal.

8. The floor drain according to claim 5 wherein said support post footing and said base bottom are uniformly cast.

9. The floor drain according to claim 5 wherein said support post footing and said base bottom are cast separately whereby said support post footing has an angled bottom surface with a slope equal to that of said base bottom thereby ensuring that said support post'"'"'s top surface is horizontal.

10. A floor drain with a detachable cover comprising:

a. a base having a downwardly sloping bottom and sides extending vertically upward from said bottom'"'"'s outer edges, said bottom having;

(1) a drainage hole positioned in its center with a cylindrical side extending vertically downward from said hole'"'"'s edges,

(2) at least two truncated cylindrical support post footings positioned near each of said bottom'"'"'s outer edges and having threaded holes centered and countersunk therein,

(3) an equal number of support posts equal in diameter to said support post footings, said support posts having threaded holes equal in diameter to that of said holes in said footings, centered and countersunk therein, with said support post firmly attached to said support post footing by a screw; and

b. a generally detachable insert similar in shape to said base but with smaller linear dimensions than those of said base and having a horizontal bottom that rests upon said support posts so as to create a horizontal channel between said bottom of said base and said bottom of said detachable insert, said bottom of said detachable insert having sides extending vertically upward from said bottom'"'"'s outer edges so as to be equal in height to said sides of said base and creating a vertical channel between said sides of said base and said sides of said detachable insert, said bottom having;

(1) one or more drain holes positioned at or near the center of said bottom,

(2) a number of cylindrically-segmented equal to that of said support posts and said support post footings, said securing wedges extending vertically downward from said bottom'"'"'s underside, each of said securing wedges having a concave inner surface facing said bottom'"'"'s outer corners, a diameter equal to that of said support posts, and positioned on said underside so that said inner surface of each securing wedge is directly over said side of a corresponding support post thereby creating surface-to-surface contact between said four inner surfaces and said four sides of said support posts when said detachable insert is inserted into said base.

11. The floor drain according to claim 10 wherein said support post footing and said base bottom are uniformly cast.

12. The floor drain according to claim 10 wherein said support post footing and said base bottom are cast separately whereby said support post footing has an angled bottom surface with a slope equal to that of said base bottom thereby ensuring that said support post'"'"'s top surface is horizontal.

13. The floor drain according to claim 10 further comprising two solid truncated pyramidal metal tabs extending perpendicularly from said cylindrical side, said tabs capable of receiving set screws to attach said drain to a waste water pipe thereby permitting removal of said base from said waste water pipe in the event of damage to said base.

14. The floor drain according to claim 10 further comprising one or more horizontal grooves each separately cast or gouged into and centered on one or more inner surfaces of one or more of said detachable insert'"'"'s sides.

15. The floor drain according to claim 13 wherein said support post footing and said base bottom are uniformly cast.

16. The floor drain according to claim 13 wherein said support post footing and said base bottom are cast separately whereby said support post footing has an angled bottom surface with a slope equal to that of said base bottom thereby ensuring that said support post'"'"'s top surface is horizontal.
