Abstract
A dual articulated faucet for minimizing or eliminating water outsplash from lavatory bowls. The faucet includes a tubular body, a pivotable spout arm, and a swivel spout. The pivotable spout arm is adapted to rotate around a first articulated point in a first plane that is parallel to the axis of the tubular body. The swivel spout is positioned at the end of the pivotable spout arm, and is in turn pivotable at a second articulated point in a second plane that is parallel to or overlapping with the first plane. By adjusting the angular position of the pivotable spout arm, and the angular position of the swivel spout, the water throw into the lavatory bowl can be adjusted to minimize or eliminate outsplash.
Description
- This application claims the benefit, pursuant to 35 U.S.C. §119(e), of U.S. provisional patent application No. 60/746,091 filed May 1, 2006, entitled “DUAL ARTICULATED FAUCET FOR LAVATORY BOWLS,” which is incorporated herein by reference in its entirety.
- The present invention generally relates to lavatory faucets, and in particular relates to a dual articulated faucet designed for use with multiple types, styles, and sizes of lavatory bowls, that is adjustable in three dimensions to prevent outsplash.
- There are three main types of lavatory bowls: drop-in (with a rim), under counter (mounts under the countertop) and vessel style (above the counter). There are likewise various arrangements of water faucets for providing water into the bowl for washing and related uses. Lavatory bowls and faucets can be combined to provide a wide variety of configurations and arrangements.
- Some arrangements of faucets and bowls result in a tendency for a lavatory user and the counter surrounding the bowl to get unexpectedly wet. This is usually due to the form of the lavatory bowl combined with the water stream from the faucet into the bowl. Such an arrangement is shown in
FIG. 1 , which illustrates a conventional (prior art)faucet 10 in combination with alavatory bowl 12, wherewater 15 from the lavatory and faucet is not confined to within the bowl. When the user turns on the faucet, the velocity of the water stream emanating from thefaucet 10, the angle of the faucet spout, the shape and size of thebowl 12, and other factors can contribute to allow water to rise out of the bowl above the rim and onto the surroundings. This undesirable spreading or spraying ofwater 15 from the lavatory bowl is sometimes called “outsplash.” - Factors that cause water outsplash include the velocity of the water stream, the shape of bowl interior, the “throw” of the water stream (i.e., where it lands in the bowl), the “throw” landing on the pop up dome or stopper, and the combination of the “throw” together with the velocity and the interior shape of the bowl.
- One way to control outsplash is to provide a user-adjustable faucet. However, many applications for faucets do not lend themselves to providing user-adjustability, e.g. public facilities. Furthermore, some adjustable faucets are simply aesthetically unattractive.
- Some faucets are specifically adjustable for a purpose, for example to allow a nozzle or spray head to be moved for dish washing or similar cleaning. Some faucets have spout ends that swivel, but these spouts are mainly for sink cleaning or for use as a drinking fountain. Other faucets may have pull-out sprays on flexible hoses, but these pull-out sprays are used mostly as kitchen faucets for cleaning pots, pans, and the sink. These faucets do not address the problem of water outsplash for a variety of lavatory bowl configurations.
- U.S. Pat. No. 6,425,149 to Wang describes a connection device for connecting an extension tube to a faucet. This device shows a plurality of extension tubes that adjoin to provide an extension tube. Although this device allows an extension, it is an extension device and does not provide an attractive and suitable device for minimizing outsplash in a lavatory bowl.
- U.S. Pat. No. 5,647,393 to Egli describes a single-point armature for a single lever faucet, and provides for a point of rotation of the faucet, but does not provide a comprehensive and attractive solution for minimizing outsplash.
- U.S. Pat. No. 6,058,973 to MacAusland et al. describes an improved valve mechanism for a faucet, and illustrates some degree of adjustability of water flow, but does not allow control of the water throw into the basin, as the spout is integrated with the valve mechanism.
- The foregoing approaches and devices each have certain shortcomings as regards providing for adjusting of the throw of water so as to minimize outsplash in a lavatory basin. Therefore, there is a need for an improved faucet arrangement that allows adjustment to prevent water outsplash for various different lavatory bowls and arrangements.
- The present invention seeks to solve the problem of water outsplash from a lavatory bowl, which frequently occurs in conventional faucets, by providing a faucet that allows an user to easily and flexibly adjust a water throw direction in three dimensions and thereby curbs the problem of water outsplash from the lavatory bowl.
- Briefly described, and according to one aspect, the present invention is a dual articulated faucet for lavatory bowls for controlling water emitted into the bowl to minimize outsplash from the bowl. The faucet comprises an elongate tubular body mountable in proximity to a lavatory bowl, the body receiving a supply of water, the body including a water port along the surface thereof. The faucet further includes a water controlling handle affixed to the body for controlling the flow of water from the water port. The faucet further comprises a pivotable spout arm affixed at a first end to the body along the length thereof, rotatable in a plane parallel to the axis of the body and in fluid communication with the water port. The faucet further comprises a swivel spout affixed to a second end of the pivotable spout arm, rotatable in a plane parallel with the rotatable axis of the spout arm, the spout including a water outlet for emitting water. By adjusting the position of the pivotable spout arm and the swivel spout may be adjusted to as to minimize the outsplash of water from a lavatory bowl.
