BACKGROUND OF THE INVENTION
A. Field of the Invention
The present invention relates to the field of toilets and their respective closet flanges, more specifically, a uniquely designed and operable closet flange for use with a respective toilet.
Toilets are typically secured to the floor via a closet flange. Usually, a wax ring is inserted between the bottom of the toilet and the closet flange in order to form a watertight seal there between. Closet flanges usually include a couple of bolts that are directed upwardly and align with holes on the base of the toilet in order to bolt and secure said toilet thereon. However, traditional closet flanges only offer a limited amount of stability to the toilet. Depending upon the size of the end user, the toilet can tilt to either aide during repeated uses, and become unsealed with the closet flange, which is less than desirable.
A need exist for an auxiliary closet flange that secures the base of the toilet from around the rear of the base, and which includes means to secure said auxiliary closet flange to the adjacent floor. The device of the present application seeks to address this need by providing a U-shaped closet flange that attaches to and encircles a rear portion of the base of the toilet from above the floor surface, and which provides greater stability to the toilet when in use.
B. Discussion of the Prior Art
As a preliminary note, it should be stated that there is an ample amount of prior art that deals with closet flanges, generally speaking. As will be discussed below, no piece of prior art discloses a U-shaped closet flange that fits around the rear base as well as across tops of opposing side lips of said base of said toilet from above the floor surface, and which operates with a toilet that is seated onto an existing closet flange in order to further support said toilet in place; wherein the U-shaped closet flange is constructed of two parallel members that include grooves to accommodate varying locales of bolts and bolt holes that extend up through the base of the toilet; wherein the parallel members each include parallel base members that engage the floor surface, and interconnect with a cross member; wherein the parallel base members and the parallel members work to extend over top of the opposing side lips of the base of the toilet; wherein the parallel members include a plurality of holes to enable screws to secure both the U-shaped closet flange and toilet in place to the surrounding floor.
The Laher Patent Application Publication (U.S. Pub. No. 2008/0000018) discloses a bracket assembly for fixing a sink, a commode, a bidet, or a urinal bowl to the floor surface of a bathroom. However, the bracket assembly does not work with an existing toilet seated atop of an existing closet flange in order to provide increased stability from above the floor surface.

DETAILED DESCRIPTION OF THE EMBODIMENT
Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in FIGS. 1-8. A U-shaped closet flange 100 (hereinafter invention) includes two generally parallel members 101 that are separated from one another by a distance 102. The parallel members 101 each include a base parallel member 103 that are separated by a base distance 104. The base parallel members 103 are also parallel with one another, and align with an outer surface 105 of the parallel members 101.
A cross member 106 connects to the base parallel members 103, and collectively form a U-shape (see FIG. 3). The base parallel members 103 and the cross member 106 include a plurality of holes 107 that are strategically placed in order to provide means of securing the invention 100 to a surrounding floor surface 140. The cross member 106, the base parallel members 103, and the parallel members 101 may be collectively made of the same material. However, the cross member 106 and the base parallel members 103 are made of the same material in that the components form a single object, which is secured to the parallel members 101. The invention 100 may be made of a material comprising a plastic, a wood, a metal, a carbon fiber composite, or a ceramic.
The parallel members 101 each include grooves 108 integrated into their design. The grooves 108 enable the invention 100 to secure itself to a base 130 of a toilet. Moreover, the grooves 108 enable different toilet shapes and sizes to work in connection with the invention 100. Also, the grooves 108 form a shoulder 109 atop of the holes 107 to enable a floor fastener 160 to secure the invention 100 to the floor surface 140. It shall be noted that the term floor fastener 160 is being loosely used to define a wood screw that has a fastener head 161 that rests against the shoulder 109 thereby securing the invention 100 to the floor surface.
Referring to FIGS. 4-6, the base 130 is seated to a closet flange 131 located on the floor surface 140. Moreover, a wax ring 132 is sandwiched between the base 130 and the closet flange 131 in order to form a watertight seal there between. The invention 100 is installed once the base 130 is seated to the closet flange 131 with the wax ring 132 sandwiched there between.
The base 130 of the toilet typically includes bolt holes 133 that are located on opposing side lips 134. The closet flange 131 usually includes two bolts 136 that are directed upwardly and extend through the bolt holes 133 in order to secure the base 130 of the toilet to the closet flange 131 via nuts 137. The invention 100 is designed to wrap around a rear portion of the base 130 of the toilet as well as to cover a top surface 135 of the opposing side lips 134. Once the invention 100 is correctly placed around the base 130, and over the opposing side lips 134 and ground surface 140, the fastening means 160 are used to secure the invention 100 to the ground surface 140. In referring to FIG. 8, it shall be noted that an inner surface 110 of the base parallel members 103 shall engage against sides of the opposing side lips 134 of the base 130 of the toilet 130.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention 100, to include variations in size, materials, shape, form, function, and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention 100.
It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
