BACKGROUND OF THE INVENTION1. 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 devices in spas, swimming pools, tubs, and the like, that include an alternate flowpath for the water through the device, or an alternate outlet for water from the device, so that debris and sediment trapped inside the device may be removed from the device.
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 devices are generally custom-made for each particular artificial body of water. That is, such devices must be sized and configured to fit a specific water structure. Often, these waterfall devices 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 waterfall devices must have an independent filtering system and cleaning system so that the waterfall device does not become plugged with debris. As such, prior art waterfall devices tend to be relatively costly, difficult to install, and/or impossible to maintain.
A typical problem experienced by conventional waterfall devices 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 waterfall waterjet. This debris can build up inside and affect the operation of the waterfall device.
Accordingly, there is a need for a device 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 device 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 device that has a means for removing debris that may become trapped in 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 waterjet that produces a waterfall into a spa, swimming pool, tub, reservoir, or the like, and that incorporates an alternate flowpath for the water through the device, or an alternate outlet, so that debris trapped inside the device can be flushed out. The device also provides a means for filling such a reservoir with water. 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. The invention generally is a device that can be installed on the edge of a spa to provide for the addition of an aesthetically pleasing and decorative waterfall that flows into a spa. In the invention, water from a water source flows into the device and is discharged through a waterfall slot/primary outlet into the spa. Because the device 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 device to the surface of the water in the spa.
The waterfall waterjet of the present invention generally comprises an round inlet, a flow/outlet selector, baffles to remove turbulence and debris from the water, a primary outlet, and a debris-removing outlet. In its simplest form, the device may comprise a waterfall waterjet (including the inlet, outlet, and optional baffles/dividers) and a flow/outlet selector to choose between two or more flow paths/outlets. When the device is in the assembled condition, that is when the various components are installed in the spa, the device appears as a generally continuous shaped structure with the waterfall slot/primary outlet in the center of the waterfall waterjet.
In one embodiment, the device comprises a first chamber and a second chamber, separated by the baffles/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 device 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 chamber and the second chamber. The first chamber preferably is a manifold structure intended for evenly distributing the water entering the device 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 device such that only the second chamber has direct access to the primary outlet. The baffles can be a single slot or a series of smaller slots or holes running approximately the length of the device. Further, the device will function even if there are no baffles, though it is likely that the waterfall will exhibit more turbulence.
The flow of water through the device 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 device. More particularly, the device may be structured to have securing ends for securing the device to the spa wall. In this preferred embodiment, the device 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 device to the spa sidewall. Due to the configuration of the device with only the inlet and 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 devices which require complex cuts and accompanying high costs of installation. The present invention is therefore also much less costly to install than other waterfall devices.
In accordance with the present invention, the device can have at least two flowpaths/outlets, one of which may be dedicated to removing debris from the waterfall waterjet. In “normal” operation, the device produces an aesthetically pleasing waterfall. In contrast, when the device is in the “debris removing” operation, either the water's flow path through the device is changed such that debris can be carried out of the device, or an alternate outlet is opened that allows water to carry the debris and sediment out of the device.
The present invention includes one or more outlets whose purpose is to allow internally trapped debris to be removed without disassembling the device. Such outlets preferably are located proximal to the lateral ends of the first chamber. Debris frequently collects at these locations because of the tendency for low flow conditions. A preferred mechanism of opening such outlets includes a bar that can slide to open and close the debris outlets and a control lever that can move the bar. When the control lever is in a first position, the debris outlets are covered and there is no flow through them. When the control lever is in a second position, the debris outlets are opened, which permits flow therethrough. In operation and use, the present invention provides an aesthetically pleasant waterfall into a spa, a means for filling the spa with water, and the ability to remove trapped debris from the device.
The device is also capable of producing an illuminated waterfall when the device includes an optional light source. The light source can be either independent from or constructed integrally with the device in order to transmit as much light as possible to the waterfall. For example, the light source can be located on the means for attaching the device to the spa wall or within the device. Further, it is preferred that that at least a portion of the device is made of a transparent material.
The device can be used on almost any artificial water body. While the device is described in connection with a spa, it is understood that the device can be used on spas, swimming pools, tubs, and the like. For example, the device 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 device 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 like components throughout the several views.

Other mechanisms can be used to open and close debris outlet 44. For example, variable apertures, rotating dials, pivoting bars or levers, and the like all can be configured proximal to debris outlets 44. Each of these alternative means, as well as others, are known in the art, and it is contemplated that each of these alternative means, as well as others, can be used as the means for opening and closing debris outlet.
In operation and use, waterfall waterjet 16 provides an aesthetically pleasant waterfall 20 into a spa 10. As waterfall waterjet 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 waterjet 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 waterjet 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 waterjet 16 helps accomplish this.
Waterfall waterjet 16 is attached to spa sidewall 12 via inlet 38 and one or more attachment means, such as threaded connecting posts 50, which fit through cooperating and similarly sized holes in spa sidewall 12 and have respective nuts/fasteners 52 that screw onto posts 50 so as to hold waterfall waterjet 16 securely and tightly onto spa sidewall 12. A hose or other water supply means (not shown) also can be attached to inlet 38 for providing water to waterfall waterjet 16. Posts 50 can be any size or shape and are shown alternatively as a small diameter tube in
Preferably, connections between base 54, bar 46, body cover 22, and cap/cover 24 are as watertight as possible. If the connections between the various components of waterfall waterjet 16 are not watertight, water may escape though the connections. In some cases, it may be optimal to use fillers, sealants, o-rings or the equivalent to help ensure watertight connection between the parts of waterfall waterjet 16, particularly between bar first surface 58 and cradle interior bottom surface 84. Methods for ensuring a watertight connection between parts or plumbing parts are known by one of ordinary skill in the art. Further, the various components of waterfall waterjet 16 may be attached by any appropriate means, including gluing and sonic welding.
As waterfall waterjets typically are unitary devices with the individual parts having been glued, welded or otherwise adhered together, access to the interior of the waterfall waterjet often is impossible. Therefore, the debris outlets 44 of the present invention allow for the cleaning of waterfall waterjets that otherwise may not have been able to be cleaned. Prior art waterfall waterjets can become clogged with debris 100 and/or sediment 102 and, if a unitary device without debris outlets 44 or a non-unitary device (that is, a device with component parts that can be separated form each other) with inadequate access to the interior of the device becomes clogged with debris 100 and/or sediment 102, such a device likely would have to be removed from the spa, discarded and replaced with another device. 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 waterjet 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 waterjet 16 with interchangeable waterfalls 20.
In a further preferred embodiment, baffles/divider 34 may include, or be comprised of, a light emitting device to more effectively transmit light to the water stream at a point close to waterfall slot/primary outlet 18 in order to provide increased transmission of light to the waterfall 20. It is also acceptable if receiving water 36 is situated at a proximal end of waterfall waterjet 16, such as through posts 50, and an illumination device 104 is positioned more centrally, such as at inlet 38. For example, one or more of posts 50 could serve as the water inlet while inlet 38 could serve as an attachment post.
Waterfall waterjet 16 can be manufactured from relatively inexpensive materials. For example, waterfall waterjet 16 can be formed of plastics, metal, or other materials. Preferably, waterfall waterjet 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 of 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.
