Definitions
- the present invention relates to spray heads, and particularly to spray heads coupled to faucets. More particularly, the invention relates to spray heads that extend from the end of the faucet and generally continue with the same diameter as the faucet, eliminating the need for an enlarged outlet end.
- Spray heads have been known in the art for years and include two types.
- the first type of spray head is mounted to a sink deck at a distance from a faucet.
- these spray heads were coupled to the faucet by a hose and allowed a user to direct a spray of water to various parts of the sink that could not be reached by the faucet.
- a typical installation is illustrated in U.S. Design Pat. No. 390,915 to Futo et al.
- the second type of spray head is mounted to the distal end of the faucet.
- This type of spray head is usually threaded into the distal end of the faucet and includes a member that moves axially between a first position that provides an aerated stream of water, and a second position that provides a spray of water.
- This type of installation is disclosed in U.S. Pat. No. 4,221,337 to Shames et al.
- the advantage of this type of spray head is that it eliminates the need for an extra hole in the sink deck or frees an existing hole for another use, such as a soap dispenser or air gap.
- One disadvantage of this type of spray head is that it is unable to direct a spray to many parts of the sink. Another disadvantage is that once the spray mode is selected, the user must manually reselect the aerated stream mode.
- spray heads have been integrated with the faucet to combine the advantages of both. These integrated spray heads pull out of the faucet and allow a user to direct a spray at any part of the sink while freeing a hole for other uses.
- these integrated spray heads are generally larger than the spout of the faucet due to the mechanism required to change between the aerated stream and the spray.
- These enlarged spray heads have proven disadvantageous when trying to design attractive faucets.
- Another disadvantage with conventional integrated spray heads is that once the spray function is selected, the user must continue to hold the actuator in position to retain the function. If the user releases the actuator, the spray head reverts to the aerated stream, which can be inconvenient.
- the present invention overcomes the above-cited disadvantages and others by providing a compact pull-out spray head that can fit within the diameter of the spout and automatically retains the spray head in the spray mode without requiring the user to continually hold the actuator.
- a spray head comprises a flexible conduit for coupling the spray head to a faucet, a shell coupled to the conduit, and an aerator coupled to the shell for providing an aerator mode of operation.
- a spray ring is disposed between the aerator and the shell for providing a spray mode of operation, wherein the spray ring cooperates with the shell to provide a plurality of fluid channels.
- the spray head further includes a diverter that has a piston and actuator. The actuator moves the piston between a first position, wherein the spray head operates in the aerator mode of operation, and a second position, wherein the spray head operates in the sprayer mode of operation.
- the spray ring includes a plurality of grooves that cooperate with the shell to define the plurality of fluid channels.
- the spray ring is coupled to the aerator to form a unit, such that the spray ring and aerator are removable from the shell as a unit to facilitate cleaning of the spray ring and the aerator.
- the body includes two fluid supply passages in fluid communication with the conduit and disposed in spaced-apart relation forming an opening therebetween.
- the diverter is disposed between the passages and the aerator and sprayer. In the first position, the diverter diverts a stream of fluid from the passages to the aerator, and in the second position, the diverter diverts a stream of fluid from the passages to the sprayer.
- the spray head includes a shell having a cutout and a resilient cover disposed in the cutout.
- the cover is generally flush with the shell to form a tubular shape defining an interior volume.
- the body and diverter are disposed in the shell, and the aerator/sprayer assembly has an outlet for a flow of fluid, with the outlet directing the flow of fluid along the longitudinal axis of the body.

Abstract
Description
- The present invention relates to spray heads, and particularly to spray heads coupled to faucets. More particularly, the invention relates to spray heads that extend from the end of the faucet and generally continue with the same diameter as the faucet, eliminating the need for an enlarged outlet end.
- Spray heads have been known in the art for years and include two types. The first type of spray head is mounted to a sink deck at a distance from a faucet. Known as sidesprays, these spray heads were coupled to the faucet by a hose and allowed a user to direct a spray of water to various parts of the sink that could not be reached by the faucet. A typical installation is illustrated in U.S. Design Pat. No. 390,915 to Futo et al.
- The second type of spray head is mounted to the distal end of the faucet. This type of spray head is usually threaded into the distal end of the faucet and includes a member that moves axially between a first position that provides an aerated stream of water, and a second position that provides a spray of water. This type of installation is disclosed in U.S. Pat. No. 4,221,337 to Shames et al. The advantage of this type of spray head is that it eliminates the need for an extra hole in the sink deck or frees an existing hole for another use, such as a soap dispenser or air gap. One disadvantage of this type of spray head is that it is unable to direct a spray to many parts of the sink. Another disadvantage is that once the spray mode is selected, the user must manually reselect the aerated stream mode.
- In more recent times, spray heads have been integrated with the faucet to combine the advantages of both. These integrated spray heads pull out of the faucet and allow a user to direct a spray at any part of the sink while freeing a hole for other uses. Unfortunately, these integrated spray heads are generally larger than the spout of the faucet due to the mechanism required to change between the aerated stream and the spray. These enlarged spray heads have proven disadvantageous when trying to design attractive faucets. Another disadvantage with conventional integrated spray heads is that once the spray function is selected, the user must continue to hold the actuator in position to retain the function. If the user releases the actuator, the spray head reverts to the aerated stream, which can be inconvenient.
- The present invention overcomes the above-cited disadvantages and others by providing a compact pull-out spray head that can fit within the diameter of the spout and automatically retains the spray head in the spray mode without requiring the user to continually hold the actuator.
- A spray head according to the present invention comprises a flexible conduit for coupling the spray head to a faucet, a shell coupled to the conduit, and an aerator coupled to the shell for providing an aerator mode of operation. A spray ring is disposed between the aerator and the shell for providing a spray mode of operation, wherein the spray ring cooperates with the shell to provide a plurality of fluid channels. The spray head further includes a diverter that has a piston and actuator. The actuator moves the piston between a first position, wherein the spray head operates in the aerator mode of operation, and a second position, wherein the spray head operates in the sprayer mode of operation.
- According to one aspect of the invention, the spray ring includes a plurality of grooves that cooperate with the shell to define the plurality of fluid channels. The spray ring is coupled to the aerator to form a unit, such that the spray ring and aerator are removable from the shell as a unit to facilitate cleaning of the spray ring and the aerator.
- The body includes two fluid supply passages in fluid communication with the conduit and disposed in spaced-apart relation forming an opening therebetween. The diverter is disposed between the passages and the aerator and sprayer. In the first position, the diverter diverts a stream of fluid from the passages to the aerator, and in the second position, the diverter diverts a stream of fluid from the passages to the sprayer.
- According to another aspect of the invention, the spray head includes a shell having a cutout and a resilient cover disposed in the cutout. The cover is generally flush with the shell to form a tubular shape defining an interior volume. The body and diverter are disposed in the shell, and the aerator/sprayer assembly has an outlet for a flow of fluid, with the outlet directing the flow of fluid along the longitudinal axis of the body.

spray head 10 is illustrated in FIGS. 1 and 2 in situ with afaucet assembly 12. Thespray head 10, which is coupled to a control valve 14 by means of aflexible hose 13, preferably pulls out of the faucet spout 16 to allow a user to direct a spray of water to any area of a sink. - The
spray head 10, as illustrated in FIG. 3, includes anouter shell 18, abody 20, adiverter assembly 22 coupled to thebody 20, and an aerator/sprayer assembly 24 coupled to thediverter assembly 22. - The
outer shell 18 is a curved tubular member with acutout 30 to provide user access to an actuator for thediverter assembly 22. Thecutout 30 receives aflexible cover 32 that attaches to theshell 18 so as to continue the general tubular shape of theshell 18, thereby providing a more aesthetically pleasing appearance. Theouter shell 18 includes a clip 16 configured to engage and retain thebody 20. - The
body 20 is illustrated in FIGS. 5-8. Thebody 20 includes aninlet 36 and adiverter support 38, with a pair ofparallel water passages 40 extending therebetween. Thediverter support 38 includes a pair of parallel alignment ridges 46, anannular disc 58, acentral bushing 60 for receiving a diverter piston 62 (FIG. 4), and anannular flange 64. Theparallel water passages 40 include inlet openings 42 (only one shown in FIG. 8) in theinlet 36 andoutlet openings 44 in the diverter support 38 (FIG. 7). Eachpassage 40 carries aflange 48 that includes a pin-receivingbore 50. - The
body 20 further includes anopening 52, best seen in FIG. 6, defined by thediverter support 38, theparallel water passages 40 and theinlet 36. As illustrated in FIG. 3, thediverter actuator 54 is disposed in theopening 52 and retained by apivot pin 53 extending between the pin-receivingbores 50 formed in theflanges 48. Thediverter actuator 54 engages thediverter piston 62 in theopening 52. The fact that the actuator/piston engagement occurs in theopening 52 allows theactuator 54 to remain within theshell 18, with theflexible cover 32 providing a slim design that has heretofore been unavailable. - The
diverter assembly 22 includes thediverter support 38, a diverter housing 66 coupled to thediverter support 38, thediverter piston 62, and adiverter seat 68. The diverter housing 66, illustrated in FIGS. 9-11, includes anaxis 69, abase 70, and an externally threadedcylindrical sidewall 72 extending from thebase 70. Thebase 70 includes a pair of parallel alignment grooves 74 configured to engage the alignment ridges 46, acentral opening 76 disposed between the grooves 74 and aligned with theaxis 69, and a pair ofopenings 78 offset from theaxis 69 and parallel thereto. Theopenings 78 align with the waterpassage outlet openings 44 in thediverter support 38. The base 70 further includes an annular groove 82 configured to engage theannular flange 64 on thediverter support 38, a transverse throughbore 84, and upper and lower outwardly extendingflanges lower flanges bore 84 extends between theopenings 78 and, as illustrated in FIG. 10, theopenings 78 extend beyond the axial location of the throughbore 84. Thus, water entering the housing 66 through theopenings 78 must flow in the “upstream” direction through thecentral opening 76 to get to the throughbore 84. - The
diverter piston 62 includes ashaft seal 96, typically an o-ring, and adiverter piston 98. Thediverter piston 98 is disposed between theopening 76 and thediverter seat 68 and is spring-biased against thecentral opening 76 as illustrated in FIG. 3. In this position, the water flows into thediverter assembly 22 through theopenings 78 and out through theaerator 102 as indicated by thearrows 99. In FIG. 4, thediverter piston 98 is disposed against thediverter seat 68, thereby blocking the flow of water to theaerator 102. Instead, the water flows into thecentral opening 76 to the throughbore 84 and radially outwardly to a flow channel between theouter shell 18 and the aerator/sprayer assembly 24 as indicated byarrows 101 providing a spray. In the spray position, water pressure retains thediverter piston 98 in position against thediverter seat 68, enabling the user to release pressure on theactuator 54. When the user turns off the water, the spring biasing automatically returns thediverter piston 98 to close thecentral opening 76 to reestablish an aerated stream of water. - Preferably, the
diverter support 38 is molded integrally with theinlet 36 andpassages 40 of thebody 20. Thediverter housing 68 is preferably attached to thediverter support 38 by ultrasonic welding. However, thehousing 68 can be attached to thesupport 38 by gluing, bonding, or the use of adhesives or the like. - The aerator/sprayer assembly24 includes an
aerator housing 100, an aerator insert 102 (FIGS. 15-17), aspray ring 104 and an aerator seal 106 (FIG. 3). Thehousing 100, illustrated in FIGS. 12 and 14, includes a longitudinally extendingcentral aperture 108, having aninlet 110 and anoutlet 112, and an external annular groove 114. Thecentral aperture 108 includes an internally threadedsection 116 and ashoulder 118. The threadedsection 116 is configured to engage the external threads of the diverter housing 66, while theshoulder 118 is sized to receive theaerator insert 102. Thespray ring 104, illustrated in FIGS. 13-14, is a truncated cone with acentral aperture 120 and a plurality of axially extendinggrooves 122 evenly disposed around the circumference of thering 104. Thering 104 is designed to engage theshell 18, with thegrooves 122 and shell cooperating to provide water channels for the spray function of thespray head 10.

Advantageously, theaerator removal tool 150 removes both the aerator and sprayer at the same time for cleaning. Heretofore, a user had to remove the aerator and sprayer separately which can be inconvenient. - The present invention has been described with respect to a preferred embodiment. However, it will be obvious to one of ordinary skill in the art that modifications can be made to the described embodiment without departing from the scope of the invention. For example, while the shell/cover combination has been described as tubular and is illustrated as a curvilinear cylinder, the tubular shape could have an eliptical, oval, or polygonal cross section, or combinations thereof, without departing from the scope of the claims. One feature of the invention is that the cover is flush with, and continues the shape of, the shell without adding bulges or protuberances, making the spray head a smooth extension of the spout. Of course, the spray head could also be used as a sidespray.
