Stainless steel mop sink assembly

Abstract

A mop sink assembly having a mop sink with a back wall, a left side wall, a right side wall, a front wall; and a bottom with a drain opening. The mop sink is comprised of a heavy gauge stainless steel; preferably 12 gauge 304 stainless steel. The mop sink assembly may further include a backsplash and a seamless joint seal. In practice the backsplash and the seamless joint seal are beneficially made of a fiberglass reinforced plastic.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The advantages and features of the present invention will become better understood with reference to the following detailed description and claims when taken in conjunction with the accompanying drawings, in which like elements are identified with like symbols, and in which:

(2) FIG. 1 illustrates a mop sink 10 that is in accord with the principles of the present invention;

(3) FIG. 2 illustrates the mop sink 10 of FIG. 1 installed with a FRP backsplash 20;

(4) FIG. 3 illustrates the FRP backsplash 20; and

(5) FIG. 4 illustrates a cross-sectional view of a seamless joint.

DETAILED DESCRIPTION OF THE INVENTION

(6) The preferred embodiment of the present invention is depicted in FIGS. 1 through 4. However, the invention is not limited to the specifically described embodiment. A person skilled in the art will appreciate that other embodiments of the invention are possible without deviating from the basic concept of the invention. Any such work around also falls within the scope of this invention.

(7) The terms a and an as used herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. In addition, unless otherwise denoted all directional signals such as in, out, up, down, left, and right are taken with reference to FIG. 1.

(8) Referring now to FIG. 1, the present invention describes a stainless steel mop sink 10. The mop sink 10 includes a back wall 11, a left side wall 12, a right side wall 13, a front wall 14, and a bottom 15 having a drain opening 16. The back wall 11, left side wall 12, right side wall 13, and front wall 14 define a top perimeter. As the mop sink 10 is to be installed as a built in mop sink in a commercial facility both ruggedness and some flexibility to aid ease of installation are paramount. To that end the mop sink 10 is comprised of a heavy gauge stainless steel, preferably 12 gauge (0.095 inch thick). Furthermore, since the mop sink 10 will be subjected to harsh chemicals in an aqueous environment, since both mold and bacterial growth should be suppressed, and since formability is important the mop sink 10 is preferably comprised of 304 stainless steel. In fact, 12 gauge 304 stainless steel provides a highly beneficial and possibly the optimum combination of strength and flexibility for the given application.

(9) A typical mop sink 10 would have a square top-down profile of about 36 inches on a side and have walls (back wall 11, left side wall 12, right side wall 13, and front wall 14) about 12 inches high. Those dimensions combined with the 12 gauge 304 stainless steel construction provides a very rugged, relatively lightweight structure but one that has a small but vital flexibility to assist installation. The mop sink 10 usually can be fit into a predetermined position with relative ease.

(10) Turning now to FIG. 2, the mop sink 10 is beneficially used with FRP backsplashes 20. While only two FRP backsplashes 20 are shown, that is only for purposes of illustration. A third FRP backsplash 20 might extend upwards from the right side wall 13.

(11) An important feature of the combination of the mop sink 10 and the FRP backsplashes 20 is that those components can be joined with seamless joints 22. Seamless joints 22 are not readily possible with cement mop sinks. Cement mop sinks are heavy, have wide top perimeter ledges, and have no flex workability. The inventive improvement means that the mop sink 10 will not corrode, water cannot get behind the mop sink 10, thus reducing mold and bacterial growth, and cleaning of the mop sink 10 can readily be accomplished.

(12) Referring now to FIG. 3, each FRP backsplash 20 includes a front surface 30 that rests just above a wall of the mop sink 10. Between the bottom of the FRP backsplash 20 and the top of the mop sink 10 is a gap or groove 32. Disposed within that groove 32 is a FRP joint 34.

(13) Turn now to FIG. 4 for a cross-sectional view of the FRP joint 34. The FRP joint 34 is a mushroom-shaped seal having a base 38 with a rectangular cross-section and a convex front cap 36. As the cross-section of the front cap 36 is wider than the base 38 the joint 34 includes vertical sides 43 that extend between the front cap 36 and the base 38.

(14) In use, the bottom of the base 38 sits on part of the top perimeter of the mop sink 10 while the FRP backsplash 20 sits on top of the base 38. The front cap 36 extends over adjacent portions of the FRP backsplash 20 and the part of the top perimeter of the mop sink in contact with the base 38. The sides 43 and the base 38 form a waterproof seamless joint 22 (see FIG. 2) between the portion of the top perimeter of the mop sink 10 and the FRP backsplash 20. The sides 43 and the base 38 may be coated with a silicon sealant if need or if desired.

(15) The foregoing description of a specific embodiment of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously many modifications and variations are possible in light of the above teaching. The embodiment was chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
