DETAILED DESCRIPTION OF THE INVENTION

[0032] While the present invention is susceptible of embodiment in various forms, as shown in the drawings, hereinafter will be described the presently preferred embodiments of the invention with the understanding that the present disclosure is to be considered an exemplification of the invention, and the present disclosure is not intended to limit the invention to specific embodiments illustrated.

[0033] With reference to FIGS. 1-12, the showerhead assembly 1 includes both a primary showerhead 15 and one or more ancillary showerheads 35. For purposes herein, the showerhead assembly 1 will be described as including two ancillary showerheads 35. However, the showerhead assembly may include any number of ancillary showerheads and a showerhead assembly including two ancillary showerheads is presented as simply a preferred embodiment.

[0034] The primary showerhead 15 may incorporate various constructions known to those skilled in the art. For example, as illustrated in the figures, the primary showerhead includes nozzles 23 which may have a relatively simple and traditional circular orientation for providing a simple spray pattern. However, the primary showerhead may incorporate more complex constructions for providing selectable and controllable spray patterns. Accordingly, as but an example illustrated in the figures, the showerhead assembly 1 may include a controller 93 for selectively controlling the flow of water through various conduits, such as the central conduit 19.

[0035] As best illustrated in FIGS. 4-7, the primary showerhead 15 includes a showerhead body 17 having a central conduit 19 for transporting water from a water supply to nozzles 23 which extend from a faceplate 25. In addition, the showerhead assembly 1 includes a neck portion 5 for connecting the showerhead assembly to a water source such as a male threaded pipe 99 (illustrated in FIGS. 11 and 12). To connect the showerhead assembly 1 to a male threaded pipe 99, the neck portion 15 includes a female threaded inlet 7. Furthermore, the neck portion 15 is hollow so as to include a conduit for allowing water to pass from the male threaded pipe 99 to the primary showerhead's body 17. The primary showerhead 15 may be connected to the neck portion 5 by various constructions known to those skilled in the art. However, in a preferred embodiment, the neck portion 5 and primary showerhead 15 are connected by a ball joint wherein the neck portion 5 includes a ball received within a spherical cavity found in the primary showerhead's proximal end which allows the primary showerhead 16 to swivel relative to the neck portion 5.

[0036] In a preferred embodiment illustrated in FIG. 4, the primary showerhead 15 includes a housing 29 having a cavity 31 for encapsulating the primary showerhead's body. With reference to FIGS. 1-12, the showerhead assembly's ancillary showerheads 35 include a housing 43 having one or more spray nozzles 45. Each ancillary showerhead 35 and its nozzles 45 are connected to the primary showerhead's body 17 by a flexible hose 37. To this end, as best illustrated in FIG. 7, the showerhead body includes two ancillary conduits 27 which are connected to the showerhead body's central conduit 19. Each of the flexible hoses' proximal ends 39 is connected to the ancillary conduit 27, and each of the flexible hoses' distal ends 41 is connected to an ancillary showerhead 35. The flexible hoses 37 travel through openings 33 formed in the housing 29. The housing's openings 33 are sufficiently large so as to allow the flexible hoses 37 to freely retract into the housing's cavity 31, or to slidably extend through the housing's openings 33 to exterior of the primary showerhead 15. Preferably, each of the ancillary showerheads' housing's back surfaces is substantially planar and includes a magnet 49 for affixing to metal surfaces.

[0037] A preferred showerhead assembly 1 includes a spool 55 which is rotatably mounted to the showerhead body 17. The showerhead assembly may include only one spool for winding and retracting multiple flexible hoses so that as one flexible hose is either retracted or extended, the remaining flexible hoses are extended or retracted as well. However, in the preferred embodiment illustrated in the figures, the showerhead assembly 1 includes a spool for each ancillary showerhead and flexible hose. Each spool 55 includes a circumferential surface 59 around which a flexible hose 37 can be wrapped. Preferably, the circumferential surface 59 resides within an annular recess 57 which forms a channel for accepting a flexible hose as it is wound around the spool's circumferential surface 59. Each spool 55 may be rotatably affixed to the showerhead body by any number of constructions as can be determined by those skilled in the art so as to allow one body to rotate relative to another. As illustrated in FIGS. 5-7, in a preferred embodiment, the showerhead body includes two spindles 71 which are received within holes 61 formed in each of the two spools 55. Preferably, each spool 55 is prevented from disengaging from the spindle 71 by a cover plate 87 which is affixed to the distal end of each spindle 71.

[0038] The ancillary showerhead's flexible hoses 37 are wrapped around their respective spools 55 with the rotation of the spool causing each flexible hose 37 to be retracted or extended relative to the showerhead's body 17. More specifically, as each spool 55 is rotated in a first direction so as to wind the spool, the flexible hose 37 becomes wrapped around the spool until the flexible hose is fully retracted and the ancillary showerhead housing 43 engages the primary showerhead housing 29. Preferably, the housing includes a concave recess to receive the ancillary showerhead's housing 43. Conversely, each flexible hose 37 and ancillary showerhead 35 can be extended away from the primary showerhead 15. When the ancillary showerhead 35 is pulled away from the primary showerhead 15, a flexible hose is pulled through the housing's opening 33 and the corresponding spool 55 is rotated in a second unwound direction until the flexible hose is in a fully extended unwound condition. Preferably, the showerhead assembly 1 includes a spring 83 for biasing the spool into the wound condition. The spring may be of any construction as can be determined by those skilled in the art so as to bias a rotating body. However, as illustrated in FIGS. 5 and 6, a preferred spring 83 is a flat torsional spring wherein the torsional spring's interior end is affixed to a spindle 71 and the torsional spring's exterior end is affixed to the spool 55.

[0039] As illustrated in FIGS. 4-10, the preferred showerhead assembly 1 includes a ratchet assembly which selectively inhibits the rotation of the spool 55 from rotating into the wound direction. As illustrated in the figures, the preferred ratchet assembly includes a plurality of teeth 63 which extend axially from a spool's sidewall. The teeth 63 are arranged in an annular configuration about the spool's axis of rotation. Furthermore, each tooth 63 includes an engagement edge 65 having a steep slope and a sliding edge 67 which may or may not have a steep slope. In addition, the ratchet assembly includes a movable pawl 77 which is positioned to catch against the teeth's engagement edges 65 when the spool is rotated in the wound direction so as to prevent the spool from rotating further in the wound direction. The pawl 77 is biased against the spool teeth 63 by an additional spring 84. A preferred spring 84 is a traditional coil spring.

[0040] Moreover, the ratchet assembly includes a button 85 for biasing the pawl 77 away from the spool teeth 63. The button may form part of the pawl. However, as illustrated in FIGS. 8-10, a preferred button 85 extends from the showerhead's baseplate 25 and includes a sloped rear edge 86 which engages a hook extending from the pawl 77. As illustrated in FIG. 10, depression of the button 85 causes the button's sloped edge 86 to engage the pawl's hook to retract the pawl 77 away from the spool's teeth 63. Once retracted, the flat torsional spiral spring 83 causes the spool 55 to rotate into the wound direction so as to wind the flexible hose 37 around the spool's circumferential surface 59.

[0041] As illustrated in all the figures, and particularly FIGS. 11 and 12, the showerhead assembly 1 is intended for use within a typical bathroom stall having a planar wall 97. The showerhead assembly's neck portion 5 is threadably attached to the male threads of a pipe 99. The primary showerhead 15 is positioned in the manner of a traditional showerhead. However, the ancillary showerheads 35 can be positioned anywhere against the shower stall wall 97 with such location limited only by the lengths of the flexible hoses 37. In use, a shower user positions and affixes metal wall plates 89 at desired locations upon the shower stall wall 97. As illustrated in FIGS. 4 and 12, an ancillary showerhead 35 is pulled away from the primary showerhead 15 so as to unwind a flexible hose 37 from a spool 55. The ancillary showerhead 35 is then affixed to a metal plate 89 by an ancillary showerhead's magnet 49.

[0042] In an embodiment not illustrated in the figures, the ancillary showerhead nozzles 45 are capable of tilting or pivoting relative to the shower stall wall 97. This can be accomplished utilizing hinges or pivot mounts such as a ball joint for connecting the nozzles 45 to the nozzle housing 43, or for affixing the ancillary showerhead's housing 43 against the shower stall wall 97. To return the ancillary showerhead to engagement with the primary showerhead, the aformentioned steps are reversed with the ancillary showerhead 35 being pulled away from a metal plate 89. A person then depresses the corresponding button 85 which causes a pawl 77 to disengage from spool teeth 63 to, in turn, wind the flexible hose 37 around the spool 55.

[0043] While a preferred showerhead assembly has been illustrated and described, it will be apparent that various modifications of the showerhead assembly can be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited except by the following claims. Having described my invention in such terms so as to enable a person skilled in the art to understand the invention, recreate the invention, and practice it, and having identified the presently preferred embodiments thereof, I claim:
