Primary ExaminerLaverne D. Geiger Assistant Examiner-Donald B. Massenberg Attorney-Rummler & Snow ABSTRACT: A plastic cap, the interior of which is hollow and provided with an internally threaded axial hub extending from the top to the bottom of the interior of the cap, and spaced webs supporting the boss axially. The cap is dome shaped at its upper end and contains an integrally formed hexagonalshaped lower skirt portion which is larger than the largest cross-sectional portion of the hood and an outwardly extending flange integrally formed on the lower perimeter of thc hexagonal-shaped shirt.

UNITARY PLASTIC CAP, NUT AND WASHER COMBINATION BACKGROUND OF THE INVENTION I-Ieretofore, when anchoring toilet bowls to the floor of a bathroom and/or toilet, it was customary to anchor the head of an elongated brass bolt in position in the floor so that the axis of the bolt shank would be aligned with the apertures in the lower flange of the toilet bowl. Normally a metal washer is placed over the stern of the bolt after the toilet flange is set in place and a metal screw placed thereon and turned to secure the toilet bowl solidly to the floor. There are a minimum of four such bolts used per toilet bowl. Then a ceramic domeshaped cap member is cemented over the remaining shank, the washer and the nut so as to dress up the lower portion of the toilet bowl and hide the bolt, washer and nut. However, plumbers are constantly losing the washers and nuts and time is wasted hunting up new ones. It was to overcome this problem that the present invention was conceived, as well as to decrease costs.

SUMMARY OF THE INVENTION The main objects of this invention are to provide a device of the class described, molded from plastic in one piece and having a dome-shaped head or cap with an integrally formed enlarged 'skirt depending therefrom in the form of a hexagon, and with a flange extending outwardly from the perimeter of the skirt; to provide in the foregoing device a cap andskirt which is hollow, containing an internally threaded bore extending the length of the interior of the cap and skirt with a series of webs extending between the bore and the inner surface of the device to position the bore axially and prevent movement thereof out of its axial plane; and to provide a device of the foregoing character which is simple in construction, inexpensive to manufacture and a substitute for the normal nut and washer for anchoring the bottom flange of a toilet bowl in position on a floor.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevational view of a toilet bowl with parts broken away;

FIG. 2 is a side elevational view of the cap of this invention shown on the flange of a toilet bowl;

FIG. 3 is a side elevational view of the cap of FIG. 2 secured to the anchor bolt;

FIG. 4 is a top plan view of the cap of this invention;

FIG. 5 is a bottom plan view of the cap taken generally on the lines 55 of FIG. 3;

FIG. 6 is a cross-sectional view taken on the lines 66 of FIG. 2 but showing the bolt embedded and/or anchored below the floor; and

FIG. 7 is a cross-sectional view taken on the lines 7-7 of FIG. 2.

The device of the present invention is molded in one piece, using a nonresilient plastic.

The dome-shaped cap member 10 is semicircularly shaped and has a depending tapered wall 12. The enlarged skirt 14 is integrally formed and extends downwardly from the lower perimeter of the wall 12 and is hexagonally shaped. The lower perimeter of the skirt 14 is provided with an integrally formed circular flange 16, which is larger than the cross-sectional areas of the skirt.

A cylindrical hub 18 extends axially from the inner upper surface of the cap 10, the upper end of which is integrally formed thereof, to the lower perimeter of the skirt 14. The hub 18 is held in axial alignment by the spaced webs 20 extending between the inner surfaces of the cap 10 and skirt 14 to the outer surfaces of the hub 18, as clearly shown in the drawing.

The ub 18 is threaded mteriorally as at 19 to weave the threaded shank 22 of the bolt 24. The bolt 24 is provided with an ovallike shaped head for anchoring in the area below the flooring 26 in the usual and customary manner. The shank of the bolt extends vertically and through the apertures 28 in the flange 30 of the toilet bowl 32.

It is to be understood that the device of the present invention is molded using plastics, and pigments may be added to the plastics to produce the unit in multiple colors to correspond with the ceramic toilet bowl.

Although but one specific embodiment of this invention is herein shown and described, it is to be understood that numerous details may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A toilet bowl having a peripheral flange about the lower portion thereof containing spaced apertures therein to receive the threaded shank of a holddown bolt, in combination with an all plastic device for securement to said threaded shank comprising a dome-shaped cap, an integrally formed hexagonally shaped skirt depending from said cap, an integrally formed circular flange extending outwardly from the lower perimeter of said skirt, the interior of said cap and skirt being threaded axially, and a cylindrical hub held in axial alignment by a series of integrally formed and vertically extending, radially spaced webs secured to and extending between the inner wall of the device and the outer wall of the hub.

2. The device according to claim 1 wherein the interior of the device is hollow and provided with an interiorly threaded hub extending axially therein.

3. The device according to claim 2 wherein an integrally formed circular flange extends outwardly from the lower periphery of said skirt.

4. The device according to claim 3 wherein an outwardly tapered wall is integral with and positioned between the cap and skirt.
