1. Field of the Invention
The present invention relates to universal bath tub overflow assemblies, which historically have been made in one size. Building codes require a tub overflow assembly to be incorporated in bath tubs and nearly all of these assemblies incorporate an outer exposed cover plate located on the front side of the bath tub above the drain. This exposed plate is the subject of this application. The overflow cover plate assembly nearly always is attached to the waste assembly using one or two screws, which historically are exposed and are necessarily plated to match the finish of the cover plate.
2. Prior Art
In the United States and most other countries, all bath tubs are required by code to incorporate a waste and overflow system into the drain assembly. Usually these systems incorporate a vent or port located above the drain which usually is covered by a round or rectangle plate, which necessarily plated to match the trim of tub (chrome, nickel, brass, etc.) which is affixed with one or two matching exposed screws. Some models incorporate a flip lever which controls the tub drain, but most do not.
The universal overflow cover assembly of the present invention serves as a replacement for these round or rectangular plates, with or without a flip lever.
Over time, such plates routinely discolor or the tub discolors around the 00 of the plate. When this happens they are changed, either in the same plated finish or, in a new plated finish in situations where the bathroom, during remodeling, is having the bathtub faucet finish changed, such as, from chrome finish to gold, brushed nickel or oil rubbed bronze finish.
Heretofore the cover plates have always been made the same size (00). Also, some manufactures use one screw and others use two screws to attach them over the overflow system port. And finally, not all screw lengths and thread sizes are/were the same.
Because of this, the market has faced the following problems while replacing these cover plates:
Accordingly, there is a need for a solution to these problems, which the universal overflow cover assembly and kit of the present invention solves.
According to the invention there is provided a universal tub overflow cover assembly and kit comprising a hanger, two set screws, and a two piece snap together cover plate, the assembly providing the following benefits:
Referring now to the drawings in greater detail, there is illustrated in the Figures the universal overflow cover assembly 10 made in accordance with the teachings of the present invention.
As shown, the assembly 10 is preferably provided as or in a kit 11 and comprises a cover piece 12 to which a snap on section 14 engages and a hanger 15 which is used to engage the cover piece 12 and attachable snap on section 14 over a port 16 of an overflow system 17 (
Also provided are at least two connectors 18, such as screws 18 which are used to engage the cover piece 12 to the hanger 15, which screws 18 will not be visible once the snap on section 14 is engaged to the cover piece 12.
The overflow system port 16 includes a cross bracket 20 which crosses a diameter of the port 16 and accommodates engagement thereof to either a one screw or two screw embodiment of a present day overflow cover. To this cross bracket 20 is usually engaged a hanger from an old cover which is removed by disengaging the screws 19 holding it in place. These screws 19 are reused in attachment of the hanger 15 via slots 13 therein, provided in the assembly 10 and kit 11. It will be understood that the slots 13 are positioned to accommodate either a one screw or two screw embodiment of the cross bracket 20. Once the hanger 15 is engaged to the cross bracket 20 of the port 16, securely, in a manner pulling the port 16 of outlet pipe 24 of the overflow system 17 securely against the hanger 15 and ensuring that a seal or sealing ring (not shown) of the overflow system 17 is tightly held against the hanger 15, the cover piece 12 is next engaged to the hanger 15.
It will be understood that a tub overflow cover is typically round, however this should not be construed as limiting inasmuch as the cover assembly may be provided in any useable shape. The illustrated cover piece 12 defines a major portion of a circular periphery of the round cover assembly 10 with a pie shaped cut out 25 therein. The cover piece 12 also incorporates a cover bracket 26 on an underside 33 thereof having slots 28 extending therethrough which align with openings 29 provided in the hanger 15. Once the hanger is secured to the cross bracket 20 and the cover piece 12 is suitably engaged thereover, the screws or connectors 18 provided in the kit 11 are passed through the slots 28 in the cover bracket 26, through the aligned openings 29 in the hanger 15 and then engaged to the screw slots 31 in the cross bracket 20, holding the cover piece 12 over the port 16, as best shown in
The cover assembly 10, when completed, provides a circular cover assembly 10 which has no screws or connectors showing and which can be made in the typical present day diameter or can be made of an increased diameter to cover any discolorations in the tub area surrounding the overflow port 16.
It will be understood that there may be an occasion upon which the cover assembly 10 must be removed from its engagement. For this purpose, a hole 40 is provided in the cover piece 12 which is aligned over the tongue 30 such that insertion of the top of a small tool or other object into the hole will produce a disengagement between engagement member 31 of the tongue 30 and the engagement tab 32, providing access to the screws 18.
As described above, the overflow cover assembly 10 and kit 11 of the present invention provides advantages over the prior art and advantages inherent in its design. Also, modifications may be proposed to the assembly without departing from the teachings herein. Accordingly the scope of the invention is only to be limited as necessitated by the accompanying claims.
