This invention relates generally to bathtubs, and more particularly to a combination bathtub and surround that include an interlocking tab and flange system for interlocking the bathtub and surround in a manner that facilitates installation and prevents leaks.
The prior art teaches a variety of bathtubs and surrounds which interlock in various manners:
Dabrowski, U.S. Pat. No. 8,082,608, teaches a bathing area that includes a bathtub and surround wall. The bathtub has a tub side that extends upwardly to a ledge extending transverse to the tub side. The surround wall includes a tongue (42) that fits within groove (46) in the tub ledge (30), but the groove is positioned inside of a tub flange (50), rather than behind the flange (as is the case in the present invention. The configuration of the groove being positioned behind the flange, in the present invention, prevents leaks.
Ruggles, U.S. Pat. No. 3,605,352, teaches a bathtub and surround with a similar construction.
Bullis, U.S. Pat. No. 8,332,972, teaches a bath tub surround enclosure which includes enclosure walls. The tub/receptor has an upper rim on which rests a rear wall. A side wall is pivotably connected at its upper rear to an upper front side of the rear wall and then pivots downwardly to create a horizontal watertight seal between the side and rear walls. Simultaneously, a lower retaining finger at the front bottom of the side wall catches between an insert on the upper rim and the upper rim.
Dabrowski, U.S. Pat. No. 9,027,176, teaches a bath tub surround that includes a rear and side panels having a slot flange and a hook flange. A hook-like projection on the hook flange of a first panel is extendable into a slot on the slot flange of a second panel. Another example bathing area surround includes the slot flange on a first bathing panel and the hook flange on a second bathing panel, and a seal located on at least one of the slot flange or the hook flange.
The prior art does not teach a surround wherein the tongue is positioned into a receiver that is positioned behind the flange, and does not extend downwardly into the tub ledge. The present invention fulfills these needs and provides further advantages as described in the following summary.
The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
The present invention provides a bathing area surround comprising a bathtub and a tub surround, the tub surround comprising a back panel, and two side panels, each of the back panel and the two side panels having a bottom edge and two side edges. The bathtub has a bathing basin formed by a bottom surface surrounded by an upwardly extending sidewall which extends upwardly to a rim, the bathtub further comprising a tub ledge extending outwardly from the rim, traverse to the sidewall, to an edge. The tub ledge is formed by a front portion and a rear portion connected by side portions, and a tub flange which extends upwardly from the rear portion and the side portions of the tub ledge adjacent the edge. The tub flange is shaped to form at least one inwardly extending pocket in the rear portion, and each of the side portions, which forms a tab receiving recess. The back panel and the two side panels each have downwardly extending locking tabs formed in their bottom edges, shaped to be inserted into the corresponding tab receiving recess, behind the tub flange. The back panel is then fastened to each of the two side panels via fasteners.
A primary objective of the present invention is to provide a bathing area surround having advantages not taught by the prior art.
Another objective is to provide a bathing area surround having a downwardly extending locking tab positioned behind a flange, without extending downwardly into the tub ledge.
A further objective is to provide a bathing area surround having a water-tight seam secured by fasteners.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
The accompanying drawings illustrate the present invention. In such drawings:
The above-described drawing figures illustrate the invention, a bathing area surround that is fast and easy to install, and which does not leak.
A tub flange 38 extends upwardly from or adjacent the edge 32, to help prevent leakage. In this embodiment, the tub flange 38 extends upwardly from the rear portion 34b and the side portions 36 of the tub ledge 30 adjacent the edge 32. The tub flange 38 is shaped to form at least one inwardly extending pocket 50 in the rear portion 34b, and each of the side portions 36, which forms a tab receiving recess 52. In this embodiment, the rear portion 34b includes two tab receiving recesses 52, but in other embodiments, there may be a different number of recesses 52, as deemed suitable by the manufacturer.
As shown in
In this embodiment, the locking tabs 54 are constructed of polymer plastic and are integral with the rest of the tub surround 40, but in other embodiments, the locking tabs 54 may be any material which is rigid and resilient for secure insertion into the tab receiving recesses 52 (e.g., glass fiber, metal, etc.). In this embodiment, the locking tabs 54 are tapered to facilitate installation, but in other embodiments the locking tabs 54 may be any shape that may fit in the recesses 52, e.g., round, rectangular, triangular, etc. In the present invention, the locking tabs 54 are positioned behind the tub flange 38, and do not extend downwardly into the tub ledge 30.
As used in this application, the words “a,” “an,” and “one” are defined to include one or more of the referenced item unless specifically stated otherwise. The terms “approximately” and “about” are defined to mean+/−10%, unless otherwise stated. Also, the terms “have,” “include,” “contain,” and similar terms are defined to mean “comprising” unless specifically stated otherwise. Furthermore, the terminology used in the specification provided above is hereby defined to include similar and/or equivalent terms, and/or alternative embodiments that would be considered obvious to one skilled in the art given the teachings of the present patent application. While the invention has been described with reference to at least one particular embodiment, it is to be clearly understood that the invention is not limited to these embodiments, but rather the scope of the invention is defined by claims made to the invention.
