1. Technical Field
The present invention generally is in the field of devices for generating waterfalls, and more particularly is in the field of devices for generating aesthetically pleasing waterfalls in spas, swimming pools, tubs and the like. The present invention further relates to a more cost efficient design and installation system for waterfall apparatus in spas, swimming pools, tubs, and the like, that includes a removable baffle structure so that debris, sediment and deposits trapped inside or on the interior surface of the waterfall apparatus may be removed from the waterfall apparatus.
2. Prior Art
Few applications derive more benefit from the addition of waterfalls or fountains than artificial bodies of water such as spas, swimming pools, and tubs. The popularity of waterfalls and fountains in such structures is probably associated with the numerous aesthetic and practical applications that make waterfalls desirable. More specifically, the addition of a waterfall or fountain to an artificial body of water can provide a substantial decorative effect or can provide a relaxing background sound, generated from the water flow. As such, users and owners of artificial bodies of water often desire the addition of waterfalls or fountains.
Many existing waterfall apparatuses are generally custom-made for each particular artificial body of water. That is, such waterfall apparatuses must be sized and configured to fit a specific water structure. Often, the waterfall apparatus must be integrated into the circulation and filtration system with additional materials, and they involve an array of plumbing and molding techniques. In some cases, such a waterfall apparatus must have an independent filtering system and cleaning system so that the waterfall apparatus does not become plugged with debris. As such, prior art waterfall apparatuses tend to be relatively costly, difficult to install, and/or impossible to maintain.
A typical problem experienced by the conventional waterfall apparatus is that debris and sediment become trapped. Such entrapment typically occurs in one of two fashions: (1) debris including small particles of wood, plastic, metal and other particles, often from the original installation or from the water source, become trapped behind the screens, baffles or other waterfall parts; or (2) when the water flow encounters obstructions in the flow, sediment falls out of the waterflow onto the bottom of the interior of the waterfall apparatus. This debris can build up inside the waterfall apparatus and on the baffles and affect the operation of the waterfall apparatus. Further, minerals and other component of less than pure water can deposit and build up on the interior surfaces of the waterfall apparatus, including on the baffles, thus affecting the water flow through the waterfall apparatus, and ultimately the resulting waterfall shape or effect.
Accordingly, there is a need for a waterfall apparatus that allows for the addition of a waterfall to an artificial body of water, such as a spa, swimming pool, tub or the like with a minimum of manufacturing and installation costs. There is also a need for such a waterfall apparatus to be able to be integrated into a spa, swimming pool, tub or the like without excessively disrupting or interfering with the existing filtering system. There is a further need for a waterfall apparatus that has a means for removing debris, sediment and deposits that may become trapped in or accumulate on the interior surfaces of the waterfall apparatus. It is to these needs and others that the present invention is directed.
BRIEF SUMMARY OF THE INVENTIONBriefly described, the present invention is a waterfall apparatus that produces a waterfall into a spa, swimming pool, tub, reservoir, or the like, and that incorporates a removable baffle so that debris trapped inside the waterfall apparatus can be flushed out. More specifically described, the present invention provides a structure and means for maintaining the interior baffles of a waterfall apparatus by allowing the easy and quick removal of the baffle from the waterfall apparatus without removing the waterfall apparatus from the spa wall or having to access behind the spa wall. For simplicity, spas, swimming pools, tubs or the like, and all such reservoirs, and artificial bodies of water, together or separately will be referred to as spas or a spa.
A representative waterfall apparatus that can comprise the invention generally is a waterfall apparatus that can be installed on or proximal to the edge or a spa to provide for the addition of an aesthetically pleasing and decorative waterfall that flows into a spa. In the waterfall apparatus, water from a water source flows into the interior hollow or manifold of the waterfall apparatus and is discharged through a waterfall slot/primary outlet into the spa. Because the waterfall apparatus can be placed above the surface of the water in the spa on the upper edge of the spa wall, the waterfall can be a smooth flow of falling water extending from the waterfall apparatus to the surface of the water in the spa.
The representative waterfall apparatus of the present invention generally comprises an inlet, a flow/outlet selector, baffles to remove turbulence and debris from the water, and a primary outlet for creating the waterfall. When the waterfall apparatus is in the assembled condition, that is when the various components are installed in the spa, the representative waterfall apparatus can appear as a generally continuous shaped structure with the waterfall slot/primary outlet in the center of the waterfall waterjet.
In one embodiment, the representative waterfall apparatus comprises a first chamber and a second chamber, separated by the baffles (alternatively called dividers) through which water flows. The baffles primarily remove turbulence from the water and secondarily can function as a screen to prevent debris from becoming lodged in other parts of the waterfall apparatus or being ejected into the spa. The configuration of the baffles is variable, and they can have one or more distribution slots for allowing the passage of water between the first (inlet) chamber and the second (outlet) chamber of the waterfall apparatus. The first chamber preferably is a manifold structure intended for evenly distributing the water entering the waterfall apparatus within the first chamber and the second chamber preferably is structured for channeling the water through the primary outlet. Preferably, the baffles divide the interior of the waterfall apparatus such that only the second chamber has direct access to the primary outlet that creates the waterfall into the spa. The baffles can be a single slot or a series of smaller slots or holes running approximately the length of the waterfall apparatus. Further, the waterfall apparatus will function even if there are no baffles, though it is likely that the waterfall will exhibit more turbulence.
In the present invention, the baffle section of the waterfall apparatus can be removed from the overall housing of the waterfall apparatus for cleaning and removal of trapped debris, sediment and deposits. In a first embodiment, the baffles, specifically a baffle plate, can be slid into and out of the housing along a track. In a second embodiment, the baffle plate also can be slid along a track; however the track has stops preventing the baffle plate from being completely removed from the housing, such that the baffle plate hangs from the bottom (or the selected position depending on the construction of the housing) or the housing. In a third embodiment, the baffle plate also can be slid along a track and the track also has stops preventing the baffle plate from being completely removed from the housing; however, the track and stops are structured such that the baffle plate can pivot or swing from the bottom (or the selected position depending on the construction of the housing) of the housing.
In the representative waterfall apparatus, the baffle plate is a generally rectangular vertically oriented plate having slots, holes or other pass-throughs therethrough such that the water can flow in a generally horizontal flow from the first chamber to the second chamber through the baffles. The waterfall apparatus housing is constructed to support the baffle plate in such an orientation, and in common waterfall apparatuses, the baffles or the baffle plate is a part of at least secured to the interior of the housing and cannot be moved or removed. In the present invention, the interior of the housing has vertical slots or tracks into which the movable baffle plate fits, such that the baffle plate can be slid down and out of the housing in the cleaning position and up and into the housing in the working position.
The flow of water through the waterfall apparatus occurs through regular fluid dynamics. The water may be recirculated as in most spa settings or the water may be provided from a separate water source such as a municipal water supply. Irrespective of the water source, the water flows through an inlet channel into the first chamber (typically elongated), past the baffles (if present), and into the second chamber, where the water passes out through the primary outlet into the spa.
The waterfall waterjet can be anchored to the wall or edge of a spa using any appropriate means as long as water is fed into, and water can flow out of, the waterfall apparatus. More particularly, the waterfall apparatus may be structured to have securing ends for securing the waterfall apparatus to the spa wall. In this preferred embodiment, the waterfall apparatus can be installed with a minimum of disturbance to the surrounding spa. It is further advantageous that the inlet and the attachment means are round so that a standard drill can be used to fix the waterfall apparatus to the spa sidewall. Due of the preferred configuration of the waterfall apparatus with only the inlet ad fastening means located on the dry side of the spa sidewall, potentially only a round inlet and preferably round fasteners require cuts to be made in the spa sidewall as opposed to typical waterfall apparatuses which require complex cuts and accompanying high costs of installation.
The waterfall apparatus can be used on almost any artificial water body. While the waterfall apparatus is described in connection with a spa, it is understood that the waterfall apparatus can be used on spas, swimming pools, tubs, and the like. For example, the waterfall apparatus can be placed on the edge of a swimming pool so to provide a waterfall. One of ordinary skill in the art can modify the waterfall apparatus without undue experimentation so that it can be placed on almost any artificial water body.
These features, and other features and advantages of the present invention will become more apparent to those of ordinary skill in the relevant art when the following detailed description of the preferred embodiments is read in conjunction with the appended drawings in which like reference numerals represent the components throughout the several views.

In operation and use, waterfall apparatus 16 provides an aesthetically pleasant waterfall 20 into a spa 10. As waterfall apparatus 16 preferably is located above the water surface of spa 10 on, for example, sidewall 12 of spa 10, waterfall 20 can provide a smooth flow of falling water extending from waterfall apparatus 16 to the water surface of spa 10. For aesthetic reasons waterfall 20 can be substantially smooth over its width and over its length as it flows into the water of spa 10. More particularly, waterfall 20 from waterfall apparatus 16 preferably is free of bubbles and ripples and flows as a generally continuous sheet of water. The preferred dual chambered structure of the waterfall apparatus 16 helps accomplish this.
Waterfall apparatus 16 is attached to spa sidewall 12 via inlets 36 having threaded portion 50, which fit through cooperating and similarly sized holes in spa sidewall 12 and have respective nuts/fasteners 52 that screw onto threaded portions 50 so as to hold waterfall apparatus 16 securely and tightly onto spa sidewall 12. A hose or other water supply means (not shown) also can be attached to inlet 36 for providing water to waterfall apparatus 16. Inlets 36 can be any size or shape and are shown as a larger diameter tube in the FIGS. Alternative attachment means can be a simple bolt or rod or a type of clip, depending on the type of installation or the desire of the installer.
Preferably, connections between the various components of waterfall apparatus are as watertight as possible. If the connections between the various components of waterfall apparatus 16 are not watertight, water may escape though the connections. In some cases, it may be optimal to use filters, sealants, o-rings or the equivalent to help ensure watertight connection between the parts of waterfall apparatus 16. Methods for ensuring a watertight connection between parts or plumbing parts are known by one or ordinary skill in the art. Further, the various components of waterfall apparatus 16 may be attached by any appropriate means, including gluing and sonic welding.
Water 36 first flows into inlet 36 and then into first chamber 30. The water then flows through baffles 102 in baffle plate 100. Baffle plate 100 may be configured with any number of baffle 102 holes and/or slots to allow for a more smooth and even distribution of water within waterfall apparatus 16 in general and into second chamber 32 more specifically, and to reduce turbulence, and thus to waterfall slot/primary outlet 18. Because of the nature of water flow, second chamber 32 will readily fill with water. To help evenly distribute water within second chamber 32, a series of baffles 102 can be used on baffle plate 100 rather than a single distribution slot so as to interrupt the flow of water from first chamber 30 to second chamber 32, thus causing water to fill first chamber 30 relatively evenly, with the water then being forced through baffles 102 into second chamber 32. By allowing for the more even distribution of water from first chamber 30 to second chamber 32, waterfall apparatus 16 can distribute water through waterfall slot/primary outlet 18 more effectively. As such, it is possible to generate a more even flow to second chamber 32 and thus a more even waterfall 20 from waterfall apparatus 16.
If debris becomes trapped behind (upstream of in first chamber 30) baffle plate 100 on back surface 40, baffle plate 100 can be slid down and out of housing 22 for cleaning or replacement. In addition, it is common for deposits or minerals in the water to deposit or build up on baffle plate 100. So, similarly, if deposits deposit or build up on baffle plate 100, baffle plate can be slid down and out of housing for cleaning or replacement.
As prior art waterfall apparatuses typically are unitary devices with the individual parts having been glued, welded or otherwise adhered together, access to the interior or such prior art waterfall apparatuses often is impossible or at least very difficult. Therefore, the removable baffle plate 100 of the present invention allows for the cleaning of the waterfall apparatus 16 of the present invention that otherwise may not have been able to be cleaned. Prior art waterfall apparatuses can become clogged with debris and/or sediment and, if a unitary waterfall apparatus without such a removable baffle plate 100 becomes clogged with debris and/or sediment, such a waterfall apparatus likely would have to be removed from the spa, discarded and replaced with another waterfall apparatus. This is avoided by the present invention.
It is understood that shape of waterfall 20 can be modified by the configuration of waterfall slot/primary outlet 18. For example, if waterfall slot/primary outlet 18 is a regular uninterrupted slit, a relatively smooth waterfall 20 over its length and width can be generated. Alternatively, if divisions or interruptions are introduced into the waterfall slot/primary outlet 18, or waterfall slot/primary outlet 18 has a non-linear shape, waterfall 20 can have a sprinkler type shape or a scalloped shape, which is not a smooth shaped waterfall. One of ordinary skill in the art can modify waterfall slot/primary outlet 18 so that waterfall apparatus 16 will produce a waterfall 20 of a desired shape. Cap/cover 24 generally is provided to shape the waterfall 20 into any of a variety of shapes, such as for example a single sheet-like waterfall, a split waterfall, or a multi-stream waterfall. Cap/cover 24 generally is glued, welded, or otherwise adhered to body cover 22 to avoid inadvertent removal, such as by falling off or by being ejected by water pressure, and inadvertent noise, such as by rattling caused by water pressure. Alternatively, cap/cover 24 can be removable so as to provide a waterfall apparatus 16 with interchangeable waterfalls 20.
As aesthetic alternatives, one or more illumination devices may be inserted into waterfall apparatus to generate an illuminated waterfall 20. In addition, one or more waterfall apparatus 16 components, such as lower end 24 and/or housing 24, can be constructed of a transparent material so that light emitted from illumination devices may be more effectively transmitted to waterfall 20. The internal surfaces of waterfall apparatus 16 can be coated with a reflective material to increase the amount of light directed to waterfall 20. Further, waterproof light sources, such as, for example, sealed diodes, can be incorporated into waterfall apparatus 16 structure or extend into the interior of waterfall apparatus 16.
Waterfall apparatus 16 can be manufactured from relatively inexpensive materials. For example, waterfall apparatus 16 can be formed of plastics, metal, or other materials. Preferably, waterfall apparatus 16 can be molded or forged from a plastic material as such material will not rust from the exposure to water, particularly chlorinated water. Such plastics, metals, and other materials are known in the art. Alternatively, for more elegant or expensive installations, waterfall waterjet can be made of more elegant or expensive materials, such as gold, silver, pewter, crystal, and the like.
The foregoing detailed description of the preferred embodiments and the appended figures have been presented only for illustrative and descriptive purposes and are not intended to be exhaustive or to limit the scope and spirit of the invention. The embodiments were selected and described to best explain the principles of the invention and its practical applications. One or ordinary skill in the art will recognize that many variations can be made to the invention disclosed in this specification without departing from the scope and spirit of the invention.
