The present invention relates to faucets having pullout sprayheads and, more particularly, to improvements in the manner by which the sprayhead is coupled and/or uncoupled from the faucet body.
Faucets having sprayheads that pull out from the faucet body enable users to manipulate the sprayhead independent of the faucet body and to aim the water spray directly at a target, instead of requiring the user to place the target under the sprayhead. Such prior art faucets typically utilize locking bayonet connectors, or connectors comprising collars and snap fingers to produce a retaining force to couple the sprayhead to the faucet body. Unfortunately, some of these prior art connectors may degrade with use. Particularly in the case of connectors formed of collars and resilient snap fingers, the retaining force often decreases with continual use. Further, the retaining force of such prior art connectors may be too great for some users to overcome, in which case the user would find it difficult to uncouple the sprayhead from the holder.
Accordingly, there is a need for a faucet having a sprayhead with a durable coupling that enables users to easily couple and uncouple the sprayhead from its holder.
The present invention generally provides a faucet having an improved coupling for use in coupling and uncoupling a pullout sprayhead from the body of the faucet. In one illustrative embodiment, the faucet includes a faucet head, a faucet body and a magnetic coupling releasably coupling the faucet head to the faucet body. In one aspect of this embodiment, the magnetic coupling may include a magnet disposed on either one of the faucet head and the faucet body, and a magnetically attractive material disposed on the other of the faucet head and the faucet body. The magnetically attractive material may include iron, steel or mixture thereof. In addition, the magnet may have a magnetic field and the other of the faucet head and the faucet body may include an electromagnet. The electromagnet is switchable between an energized state and a de-energized state, wherein in the energized state the electromagnet exhibits an electromagnetic field oriented in a direction opposite the magnetic field of the magnet and thereby repels the faucet body from the faucet head.
In an alternative aspect of this embodiment, the magnetic coupling includes a head connector disposed on the faucet head and a body connector disposed on the faucet body. Each of the head connector and body connector includes a magnet. The magnet of each of the head connector and the body connector may include a single magnetic field oriented in the same direction such that the magnetic coupling exhibits a single mode attracting the head connector to the body connector. Alternatively, the magnet of each of the head connector and the body connector may include multiple magnetic fields. In this case, a number of the multiple magnetic fields are oriented in a first direction and the remaining of the multiple magnetic fields are arranged in a second direction. The second direction is substantially opposite the first direction such that, when the multiple magnetic fields of the head connector magnet are oriented in the same direction as the multiple magnetic fields of the body connector magnet, the magnetic coupling exhibits a first attracting mode and, when the multiple magnetic fields of the head connector magnet are oriented in a direction opposite the multiple magnetic fields of the body connector magnet, the magnetic coupling exhibits a second repelling mode.
In another illustrative embodiment, the faucet includes a faucet head, a faucet body and a magnetic coupling releasably coupling the faucet head to the faucet body. The magnetic coupling includes a head connector disposed on the faucet head and a body connector disposed on the faucet body. At least one of the head connector and the body connector has a first magnet and the other of the head connector and the body connector has a magnetically attractive member. The magnetically attractive member may be formed of steel, iron or a mixture thereof. The magnetically attractive member may include a second magnet having a second magnetic field oriented in the same direction as the magnetic field of the first magnet.
According to a further illustrative embodiment, a method of coupling and uncoupling a faucet head from a faucet body is provided. The method includes the steps of providing a head connector on the faucet head, providing a body connector on the faucet body, and generating a magnetic field attracting the head connector and the body connector, thereby coupling the faucet head to the faucet body.
Additional features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrative embodiment exemplifying the best mode of carrying out the invention as presently perceived.

Base 36a includes resilient clip or snap finger 43 extending upwardly and outwardly therefrom. Slot 45 extends through neck 32 of faucet body 14 and is configured to receive clip 43. Clip 43 is snap-received within slot 45 to secure body connector member 36 in neck 32 of faucet body 14. Recess 39 extends into and about a portion of the inner periphery of base 36a. Lip 41 extends from and about a portion of the outer periphery of connecting portion 36b. Lip 41 is configured to engage with recess 39 to thereby couple connecting portion 36b to base 36a. Base 36a may be formed of any suitable material. In one embodiment, base 36a is formed of plastic and is overmolded to connecting portion 36b. It should be understood that body connector member 36 need not include two separate components. Rather base 36a and connecting portion 36b may be integrally formed as a single unit, such that body connector member 36 is one piece.

As known in the art, magnets have magnetic fields characterized by their strength and orientation. Magnetic poles are limited regions in the magnet at which the field of the magnet is most intense, each of which is designated by the approximate geographic direction to which it is attracted, north (N) or south (S). The direction of the magnetic field is the direction of a line that passes through the north and south poles of the magnet. Generally, the direction is perpendicular to the magnetic surface of the magnet. The orientation of the field may be characterized as the direction pointed to by the north pole of the magnet.
Magnets may be characterized in several different ways. For instance, the magnet type may be a permanent magnet or an electromagnet. A permanent magnet exhibits a permanent (i.e. constant) magnetic field. An electromagnet generates a magnetic field only when a flow of electric current is passed through it. The magnetic field generated by the electromagnet disappears when the current ceases.
Magnets with a single magnetic field are considered dipolar because they have two poles, a north and a south pole. The magnetic field of a dipolar magnet may interact with the magnetic field of other magnets to produce a repelling or an attracting force. The magnetic field may also interact with certain attractable materials, such as iron or steel, that are naturally attracted to magnets.
The strength of the attracting or repelling magnetic force is determined by the strength of the magnetic field of the magnet and by the degree of interaction between the magnetic field and a component that enters the field. The strength of a magnetic field is determined by the construction of the magnet. The strength of an electromagnetic field can be changed by changing the current that flows through the electromagnet. The degree of interaction is determined by the size of the magnetic surface that interacts with the component entering the field and by the distance between the magnet and the component entering the field. The magnetic force of a magnet, therefore, may be changed by changing the position of the magnet relative to another magnet or to the attractable material.
As is also well-known in the art of magnets, unlike-poles attract and like-poles repel. Accordingly, when two dipolar magnets come into close proximity and their magnetic fields are oriented in the same direction, they attract one another. The north pole on the proximal surface of one magnet attracts the south pole on the proximal surface of the other magnet. On the other hand, when two dipolar magnets come into close proximity and their magnetic fields are oriented in opposite directions, they repel one another. For example, the north pole on the proximal surface of one magnet repels the north pole on the proximal surface of the other magnet.
Magnets may also include multiple magnetic fields oriented in opposite directions. In this case, when two multi-field magnets come in close proximity to one another, they will repel one another if the multiple fields are not oriented in the same direction, and will attract one another if oriented in the same direction. As such, these multi-fold magnets provide two modes: an attracting mode and a repelling mode. Such magnets may be referred to as bi-modal.
As shown in

It should be understood that the magnetic coupling of sprayhead 10 to body 14 may be achieved without the use of multi-field magnets. Alternatively, faucet 1 may be equipped with uni-modal magnetic coupling 115 through the use of dipolar magnets, as schematically illustrated in
It should be noted that the magnetic coupling need not employ two magnets. For instance, as schematically illustrated in

Male and female members 350 and 352 may have any shape such as rectangular or triangular. However, in this particular embodiment, the curved, sloping shape of female and male members 352 and 350 may also facilitate the user's rotation of head connector member 324 relative to body connector member 336 in the case where magnetic coupling 315 is a bimodal coupling, such as that in
It should be noted that any of the above-described embodiments may also include an electromagnet. For instance, either the head connector member or the body connector member may include an electromagnet switchable between an energized state and a de-energized state. As illustrated in
