DETAILED DESCRIPTION OF THE INVENTION

(10) 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 as an exemplification of the invention, and it is not intended to limit the invention to the specific embodiments illustrated.

(11) With reference to all FIGS. 1-9, the showerhead assembly 1 includes a mounting structure 11 for supporting a handheld showerhead 47. The handheld showerhead portion of the showerhead assembly 1 has unique features but like traditional constructions includes a hollow handle 49 having a proximal end 51 which affixes to a flexible hose 41 having a first end 25 and a second end 27, and a distal end which includes a showerhead 53. The handle 49 includes a longitudinal axis, and preferably the showerhead 53 affixes to the distal end of the handle 49 at an angle, such as 45° to 90°, relative to the handle's 49 longitudinal axis. The showerhead assembly's primary showerhead 53 has a front face 55 through which a plurality of nozzles 57 project. As understood by those skilled in the art, water is capable of flowing through a central channel (not shown) within the center of the handle 49 which connects to the showerhead's nozzles 57 which are constructed to spray water. Additionally, and as illustrated in the Figures, the primary showerhead 53 comprises a rear side 99 which defines a substantially spherical cavity 15. A substantially spherical cavity is defined as having a substantial portion of its surface as having a spherical or curved shape, but wherein a portion of the surface may be planar such as to form a frusto-spherical shape. In a preferred embodiment, the cavity 15 is composed of rubber or plastic material. As illustrated in FIGS. 1-7, preferably the handheld showerhead's hollow handle 49 has a proximal end 51 which has male threads so as to couple to the female threads found on the first end 25 of a traditional flexible hose.

(12) The showerhead assembly 1 has a unique hollow mounting structure 11 for releasably holding the showerhead assembly's hollow handle 49. As illustrated in each of the Figures, the mount 11 includes an inlet 13 which connects to a water supply. Preferably, the inlet 13 includes female threads for connecting to the male threads found at the end of a traditional shower stall pipe. Preferably, the mount's hollow housing 19 is connected to the mount's inlet 13 by a ball and socket attachment. As illustrated in the FIGS. 4-7, the ball and socket allow the mount 11 to rotate and swivel in any direction about the ball's center.

(13) As illustrated in FIGS. 1-9, like traditional handheld showerhead mounting structures, the preferred mount 11 includes a housing 19 which has a central conduit and hose conduit which connects the inlet 13 to a primary hose outlet. Preferably, the mount's primary outlet includes male threads for connecting to the female threaded second end 27 of the flexible hose 41. Additionally, as illustrated in FIG. 1-9, the mount housing's front end defines a curved area by which a ball 33 extends therefrom. The ball 33 is sized and configured to releasably engage with the showerhead's cavity 15 and the ball's convex curved area allows the engaged showerhead cavity 15 to rotate or swivel about a central axis. The showerhead's cavity 15 defines a space correspondingly configured for receipt of the ball 33. Upon engagement of the showerhead cavity 15 with the ball 33, the handheld showerhead 47 is thereby removably and rotatably docked onto the mount 11. In a preferred embodiment, the ball 33 is composed of rubber material. In an even more preferred embodiment, the ball 33 is composed rubber and the cavity 15 is composed of rubber so as to create frictional tension therebetween and further stabilize positioning.

(14) Preferably, and as illustrated in FIGS. 3-9, the showerhead cavity 15 includes a tension pin 61 which extends axially from the cavity's planar surface 97. Even more preferably, the tension pin 61 is composed of plastic material. Additionally, the tension pin 61 is sized and configured to engage with corresponding structures that reside on the ball 33 wherein it provides tension therebetween to help maintain the showerhead handle 49 in a desired position. Specifically, the ball 33 has a distal end 77 being planar and comprising a preliminary alignment chamber 63 and a second axially aligned smaller locking chamber 65. Preferably, the preliminary alignment chamber 63 and locking chamber 65 are both spherical in shape. The locking chamber 65 is sized and positioned to engage with the tension pin 61, wherein the engagement of the tension pin 61 with the locking chamber 65 prevents over-rotation of the ball 33 or inadvertent release of the showerhead handle 49. Moreover, the preliminary alignment chamber 63 is sized and positioned for receipt of the tension pin 61. The engagement of the tension pin 61 with the preliminary alignment chamber 63 further stabilizes the connection realized between the showerhead handle 49 and the mounting structure 11 and secures the ball 33 in place so as to prevent it from popping out of the cavity 15.

(15) In another preferred embodiment, the showerhead handle 49 further comprises a spring-loaded button 88 and tab 87 mechanism. Preferably, and as best illustrated in FIGS. 4-7, the button 88 extends from the handle 49. Specifically, the button 88 is coupled with and fits on the tab 87 which is connected to the handle's rear side 99. Even more specifically, the tab 87 pivotally moves in an upward and downward trajectory and situated directly adjacent to and underneath the cavity 15. Additionally, the spring 89 is disposed within an opening 111 in the handle 49 and is arranged so as to reside between the button 88/tab 87 and the handle 49. Furthermore, the spring 89 is configured so as to compress and decompress as a function of the button 88 and tab 87 mechanism. Moreover, the tab's 87 pivotal movement is dependent on and controlled by the button 88 and thereby, the state of compression of the spring 89.

(16) Specifically, when the button 88 is not pressed, the spring 89 remains in a decompressed state and the tab 87 extends upwards so as to encapsulate the ball 33 received in the cavity 15 and thereby provide integral support for the connection experienced therebetween. Conversely, upon depression of the button 88, the spring 89 compresses and the tab 87 pivots downwardly. In this state, the tab 87 is no longer protruding upwards so as to encapsulate and provide support for the ball 33 received in the cavity 15. Various spring-loaded button and tab constructions for providing these capabilities can be selected by those skilled in the art

(17) Accordingly, as best illustrated in FIGS. 4-6, once the handheld showerhead 47 is properly engaged with the ball 33, the handheld showerhead 47 is capable of pivoting both upwardly and downwardly, as well as left and right, so as to be able to spray water throughout a shower stall, as desired by the bather.

(18) The present shower assembly provides an improved mounting structure for holding a handheld shower assembly. Advantageously, the mount 11 provides an easy connect docket for the handheld showerhead 47 in which the handheld showerhead 47 is securely positioned. Also advantageously, the ball joint connection allows the bather to orient the handheld showerhead 47 as desired so as to divert the stream of water to different locations within the shower enclosure.

(19) While preferred showerhead assemblies have been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. Alternative embodiments may be envisioned by those skilled in the art after consideration of the present disclosure. Accordingly, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention.
