The present invention relates to the field of plumbing. Specifically, the present invention is of an improved shower trim kit that is not only easy to install but also allows for greater freedom in providing a shower with a desired appearance than heretofore known. The present invention is also of a method for installing a shower trim kit and methods for making the shower trim kit.
In the art it is known to install the lion's share of the components of a shower fixture within a wall 10 in proximity of a shower head 12,
Many different types of shower fixtures exist having different types and numbers of control handles.
For example, different shower fixtures have a different number (e.g., 1, 2, 3 or more) and arrangement of outlet ports. Diversion of water to one or more of the outlet ports is performed using a diverter knob. In
For example, different fixtures have a different number (e.g., 1, 2, 3 or more) and arrangement of valve handles. Many shower fixtures include two stem valves, a first stem valve for regulating hot water flow and a second stem valve for regulating cold water flow to a mixer. Rotation of one or the other valve handle protruding from the wall and functionally associated with a respective stem valve stem allows selection of a desired water temperature and water flow rate. Many such showers fixtures include a third stem valve located at the output port of the mixer. Rotation of the valve handle protruding from the wall and functionally associated with the third stem valve allows selection of the water flow rate. Valve handles that are fit over a stem of a stem valve are known to be made of many different types of material including glass, ceramic, metals, plastics or combinations thereof. As a stem valve is made of a plumbing-compatible metal such as brass, a valve handle is generally provided with a brass adapter to engage features on the stem (e.g., serrations, flat sides, discontinuities) to allow effective rotation of the stem. As the only motion required from such a valve handle is rotation, attachment of a brass adapter to a valve handle of a given material is not technically challenging. An additional advantage of such a construction is that valve handles of various styles, shapes, materials and forms can be fitted onto standard stems and changed when desired. This allows an interior designer, esthetic freedom when designing a shower. Further, replacement of an undesired valve handle is simple and cheap to perform even by an unskilled person.
A preferred shower fixture, such as depicted in
As a shower walls such as 10 are generally covered with water-resistant tiles, the locations from whence the exterior parts of a shower fixture protrude include gaps formed by breaking or cutting the tiles. Not only are the edges of the gaps unesthetic, but the view through the gaps to the inside of wall 10 gives the whole an unhygienic, unfinished and unsophisticated “construction site” look. If the gap is not sealed, water condensing on the tiles flows down and through the gap into the interior of wall 10, defeating the purpose of the tiling and generating conditions conducive for the formation of mold and mildew in wall 10.
To overcome the problems caused by the presence of gaps in a shower wall 10, shower trim kits are used. Shower trim kits generally include a number of different components such as flanges (e.g. 26 and 28), valve trim (e.g., 30) and escutcheons (e.g., 32).
As is known to one skilled in the art, shower trim kits are not only decorative features but are functional, providing protection for the inner part of a wall and the shower fixture itself. Further, factors such as the aesthetic appearance and ease of installation of a given shower trim kit are determinants of the value of the shower trim kit.
Although effective in preventing water from passing into a wall 10 and effective in concealing gaps so that a shower is given an aesthetic finished look, prior art shower trim kits fail in a number of aspects as the various components are made of stamped metals made of or treated so as to look like chrome, brass, nickel, copper or stainless steel. Although generally attractive, cheap and simple to manufacture, stamped metal has only limited aesthetic and design possibilities. Thus a manufacturer of shower trim kits is able to offer only a limited selection of flanges and escutcheons to an interior designer from which to choose. Thus, even though valve handles for stem valves are available in many different esthetic forms and made of many different materials, an interior designer is limited to stamped metal flanges and escutcheons.
It would be advantageous to have a shower trim kit devoid of at least some of the disadvantages of the prior art. It would be most advantageous that a shower trim kit be available in many materials and shapes.

The present invention allows heretofore unknown esthetic possibilities.
Using known shower trim kits, an interior designer is limited to using stamped metal escutcheons having colors used in the field of metal coating. In contrast, by employing the teachings of the present invention, a designer is not limited in the choice of colors. In some embodiments, an outer valve handle of the present invention is installed in a shower. In some embodiments, a escutcheon of the present invention is installed in a shower. In a preferred embodiment, an escutcheon of the present invention and outer valve handle(s) are installed in a shower, especially when the valve handle(s) and the escutcheon match (for example, by color, material, pattern or theme). For example, in a shower tiled with ceramic tiles having a brown marble appearance installation of a cream colored escutcheon together with brown marble appearance outer valve handle(s) both made of an acrylic polymer giving an exceptionally attractive appearance. If a designer is no longer satisfied with the appearance of either or both the escutcheon and the outer valve handles(s), either or both are replaced without the assistance of a skilled plumber. Further, custom outer valve handles may be easily produced and installed.
Using known shower trim kits, an interior designer is limited to using substantially two-dimensional metal escutcheons of regular shape. In contrast, by employing the teachings of the present invention, a designer is not limited in the choice of shapes. For example, a designer may choose to use an animal-shaped escutcheon where the corresponding valve handle(s) (especially outer valve handle(s) of the present invention) are located at the “eye” or “limb” of the animal shape. The shape can be implemented in an irregular outline (such as an outline of an animal) as well as in a varying thickness of the escutcheon giving the escutcheon a three-dimensional form. Further, it is a relatively simple matter to differentially color an escutcheon of the present invention, especially when painted or made of a clay-like material.
An escutcheon of the present invention is generally of any desired outline and is provided with at least one hole configured to allow a component or components of the shower fixture to protrude. In embodiments of an escutcheon of the present invention configured for use with a shower fixture provided with a pressure balancing valve, the escutcheon is provided with a hole allowing attachment of a valve handle to the valve therethrough. In embodiments of an escutcheon of the present invention configured for use with a shower fixture provided with two or more stem valves, the escutcheon is provided with sufficient holes allowing the stems of the stem valves to protrude therethrough and thus allowing attachment of the shower valve handles. In some embodiments, an escutcheon of the present invention is provided with a hole configured to allow the hose of a hand-shower to protrude therethrough. In some embodiments, an escutcheon of the present invention is provided with a hole configured to allow a diverter knob to protrude therethrough.

In a preferred embodiment, an escutcheon of the present invention is made of two or more layers allowing different material properties to be combined. It is important to note that an escutcheon of the present invention is not necessarily devoid of any metal parts. Rather, the structural components of an escutcheon of the present invention are made of a non-metal material. In embodiments of the escutcheons of the present invention, some or all decorative elements of an escutcheon of the present invention include metal. In a preferred embodiment, an outer of two or more layers is transparent. Such a two-layer construction does not only provide exceptional design freedom, but also allows the use of materials heretofore unknown for fashioning escutcheons. For example, in

Preferably, coatings with which an escutcheon of the present invention is coated are water-resistant coatings.
In embodiments of the present invention, an escutcheon comprises a material that is fluorescent, phosphorescent or reflective. The material may be either or both the material from which the escutcheon is made or a coating on the material. Such embodiments are an exceptionally useful safety feature, especially in the event of a power outage or for persons desiring to make use of an unlit or otherwise dark shower cabin. In the case of a fluorescent material, it is preferred that the shower cabin in which the escutcheon is installed also include a source of ultraviolet light.
In embodiments of the present invention, at least part of an escutcheon is transparent. In a preferred embodiment, an escutcheon comprises at least two layers, where the uppermost of the layers is transparent.

Suitable solid objects include but are not limited to animal products (e.g., coral, feathers, insects, leather, shells, skeletons, spines, teeth), plant products. (e.g., bark, fruit, leaves, pits, roots, twigs, sawdust, seeds), cloth, fabric, flakes, grains, gravel, metal, paper, particles, pebbles, sand, stones, strips and wires. In
In a preferred embodiment of the present invention, the shower trim kit further comprises a switch embedded within the escutcheon, the switch preferably functionally associated with a component that is useful or entertaining. Suitable components include light-emitting components (lamps, light-emitting diodes), motion-producing components (electrical motors) and sound-producing components (music synthesizers, music players). Such embodiments provide an exceptionally useful safety feature, especially in the event of a power outage or for persons desiring to make use of an unlit or otherwise dark shower cabin.
In a preferred embodiment, the switch is functionally associated with a temperature sensor so that the switch toggles between an activated and deactivated state dependent on output from the temperature sensor, e.g., when the temperature in the shower cabin is above a certain predetermined level.
In a preferred embodiment, the solid object inside the escutcheon is light-emitting (e.g., light-emitting diode, lamp). Preferably such a light-emitting object is functionally associated with a switch configured to activate and deactivate the light emission of the solid object. In a preferred embodiment the switch is functionally associated with a temperature sensor such as a thermocouple and the switch is configured to activate the light-emitting object when the temperature sensor senses a given range of temperatures.

Just as an escutcheon of the present invention, embodiments of an outer valve handle of the present invention are made of substantially of one layer of a material or of two or more layers allowing different material properties to be combined. In a preferred embodiment, an outer of two or more layers is transparent. For example, in
Just as an escutcheon of the present, invention; embodiments of an outer valve handle of the present invention are coated with a coating. A specific coating is chosen to suit the material from which the outer valve handle is made and to provide the outer valve handle with desired properties or a desired appearance. Suitable coatings include, but are not limited to, enamels, epoxies, glasses, lacquers, paints, physical vapor deposits, plastics, polymers, powder coatings, shellacs, stains and water-resistant coatings. Preferably coatings with which an outer valve handle of the present invention is coated are water-resistant coatings.

In embodiments of the present invention, at least part of an outer valve handle is transparent. In a preferred embodiment, an outer valve handle comprises at least two layers, where the uppermost of the layers is transparent. As with an escutcheon of the present invention, in a preferred embodiment there is a solid object or many solid objects suspended or held inside the transparent part of the outer valve handle.

As noted hereinabove, prior art valve handles of pressure balancing valves are of substantially unitary construction. Replacement or installation of such a valve handle includes replacing or installing the whole handle, including the part that actually interfaces with a respective pressure balancing valve, requiring intervention of a skilled plumber. Unlike prior art valve handles, an outer valve handle of the present invention is part of a shower trim kit and is designed to fit over a valve handle of a pressure balancing valve. Therefore, embodiments of an outer valve handle of the present invention includes a hollowed-out interior volume configured to receive a valve handle of a pressure balancing valve. It is important to note that when implementing the teachings of the present invention, a pressure balancing valve is preferably provided together with a simple and unfinished valve handle specially configured to fit within a hollowed out interior volume of a outer valve handle of a shower trim kit of the present invention. In
It is generally preferred to provide an outer valve handle of the present invention with a structural feature or to provide an additional component to the shower trim kit to fix the outer valve handle in place over the valve handle. In an embodiment, a shower trim kit of the present invention includes a compressible fixing component configured to apply a force on the valve handle and on the surface of the hollowed-out interior volume of the outer valve handle thus fixing the outer valve handle in place. In
The present invention provides a method of installing components of a shower trim kit, specifically escutcheons and valve handles for pressure-balancing valves.
According to the methods known in the art, stamped metal escutcheons are held in place using screws, bolts or the like, requiring the use of a peripheral seal. Due to the length and lack of rigidity of such a seal, the seal is difficult to put precisely in place, often giving the shower cabin an unprofessional look and providing insufficient sealing that leads to leakage of water into the wall. Further the use of screws to hold a stamped metal plate escutcheon in place may lead to bending or warping of the escutcheon when excessively tightened.
In a first aspect, the method of the present invention is a method of installing an escutcheon over a shower fixture located inside a wall, by providing a non-metal escutcheon having at least one hole therethrough and affixing the escutcheon in place so that a component of the shower fixture (such as a valve handle) is accessible through the at least one hole. Unlike prior art methods, the method of the present invention of installing escutcheon cannot bend or warp the escutcheon.
In an embodiment of the present invention, the escutcheon-is affixed to a wall by sticking the escutcheon to the wall using, for example, an adhesive, adhesive tape, caulk, polymerizable materials, sealant-or silicon rubber. In
In an embodiment of the present invention, the escutcheon is affixed in place by friction. The escutcheon is placed so that a part of the shower fixture protrudes through a hole in the escutcheon and an elastic holding member (e.g. a ring-shaped member such as a rubber O-ring) is snugly placed about the protruding part of the shower fixture so as to press the escutcheon in place against the wall. In
In a second aspect, the method of the present invention is a method of installing an outer valve handle over a valve handle of a pressure balancing valve located inside a wall, by providing an outer valve handle configured to fit over the valve handle (such as an outer valve handle of the present invention) and placing the outer, valve handle over the valve handle, for example by pushing the outer valve handle over the valve handle.
Details of installation of an outer valve handle according to the present invention are clear to one of average skill in the art upon perusal of the description and figures, especially
The method of the present invention is exceptionally useful in the field of plumbing and construction. For example, in a large apartment block or a hotel under construction, shower fixtures with associated valve handles (such as valve handles 36 in
An escutcheon of the is produced using any suitable method known in the art. Suitable methods include methods that employ one or more techniques including, but not limited to, carving, casting, injection-molding, and molding and are generally determined by the type of the material from which an escutcheon is made.
The preferred methods of producing an escutcheon of the present invention include molding techniques and carving, techniques. Molding allows many different and desirable surface features, shapes and textures to be designed and applied to a escutcheon of the present invention and also allows an escutcheon having three-dimensional features to be fashioned.
Generally, an escutcheon of the present invention having a hole therethrough is made by providing a moldable precursor material and placing the moldable precursor material in an escutcheon-shaped mold. The shape and any features in the mold are fixed in the moldable precursor material so as to fashion an incipient escutcheon. After any further required processing of the incipient escutcheon (which may be limited to simply separating the template from the escutcheon), the escutcheon of the present invention is complete.
In embodiments of the present invention, the escutcheon-shaped mold includes a part that corresponds to the hole of the escutcheon. In embodiments of the present invention, subsequent to the fixing of the moldable precursor material, a hole is made in the incipient escutcheon, for example by boring, drilling or trephining.
Moldable precursor materials are generally precursors of materials listed above as being suitable for fashioning a escutcheon of the present invention by molding. Generally, a moldable precursor material is a reversibly deformable before setting, that is a material that is capable of recovering shape after deformation and includes but is not limited to fluids, liquids, powders, foams, polymerizable materials and thermoplastic materials.
Generally, once the moldable precursor material fills the escutcheon-shaped mold, the precursor material must be fixed so as to become solid. Depending on the identity of the moldable precursor material, fixing includes, but is not limited to, methods such as heating the precursor material, cooling the precursor material, curing the precursor material, polymerizing the precursor material, cooling the precursor material, irradiating the precursor material, illuminating the precursor material, exposing the precursor material to a fixative and waiting a period of time. By fixative is meant an agent that causes the precursor material to change to the fixed state and is used herein as a general term for such materials as fixatives, hardeners, polymerization/crosslinking/curing initiators, catalysts and agents. It is important to note that in some cases a precursor material is produced by mixing two or more components which thereafter change to a fixed state, for example, by simply waiting a period of time.
In a preferred embodiment, the moldable precursor material includes a thermoplastic material at plastic temperature and the fixing comprises cooling the thermoplastic material, for example as part of a thermoforming process.
In another preferred embodiment, the moldable precursor material is a polymerizable material (e.g., a monomer solution, a crosslinkable polymer, a vulcanizable polymers, a polymerizable fluids or a thermosetting resin). The polymerizable material is polymerized, fixing the precursor material and thus making the incipient escutcheon.
Processing an incipient escutcheon generally includes giving the incipient escutcheon a final shape. Such processing includes adding a hole in the incipient escutcheon, as discussed above. Such processing also optionally includes treating the surface to modify or change the texture of the escutcheon surface, for example by abrading, brushing, polishing, sand blasting or sanding the surface. Such processing also optionally includes coating the outer surfaces of the incipient escutcheon by methods including but not limited to coloring, lacquering, painting, shellacing spraying, staining and varnishing.
In a preferred embodiment, an additional, preferably decorative, material is added the the moldable precursor material prior to fixing. Examples of suitable additional materials include animal products (e.g., coral, feathers, insects, leather, shells, skeletons, spines and teeth), plant products (e.g., bark, fruit, leaves, needles, pits, roots, twigs, sawdust and seeds), as well as cloth, fabric, flakes, grains, gravel, metal, paper, particles, pebbles, sand, stones, strips and wires. Such adding is most advantageously performed when the escutcheon is transparent subsequent to fixing allowing the added material to be seen.
As the technical details of the techniques recited above are well known, one skilled in the art is able to implement the teachings of the present invention subsequent to perusal of the specification. That said, in a specific example, a model of the escutcheon is made, for example, in wood or plastic by carving or using computer-aided design methods. The model is then transferred to a vacuum forming device to produce a mold of the escutcheon. When the vacuum-formed mold is complete, the moldable precursor material is poured into the mold to produce an escutcheon of the present invention.
An escutcheon 32 of
An additional preferred method of the present invention is useful in making a escutcheon of the present invention from relatively soft workable materials such as paper, recycled paper, paper mache, wood, and wood products such as plywood. The material is first made into the desired shape, for example by carving or lathing. If desired, surface features, textures and patterns are applied. The incipient escutcheon thus made is then optionally processed further, for example, by sanding, staining, coating or painting. The incipient escutcheon is then impregnated or coated with epoxy, polyester or other water resistant or water repellent material.
