Valve assembly

Abstract

A valve assembly for controlling flow of water to a shower head includes a tube, which is insertable between and attachable to an inlet pipe for a shower enclosure and a shower head. A valve positioned in the tube regulates a flow of water through the tube. A shaft is attached the valve and extends through a sidewall of the tube and a housing. A biaser positioned in the housing is operationally engaged to the shaft and biases the valve to an open configuration. A lever arm is attached to and extends from the shaft. A handle is attached to the lever arm distal from the shaft. The handle can be moved by a user from a first position to a second position, thus actuating the biaser to rotate the valve from a closed configuration to the open configuration so that water flows through the tube to the shower head.

DETAILED DESCRIPTION OF THE INVENTION

(14) With reference now to the drawings, and in particular to FIGS. 1 through 12 thereof, a new valve assembly embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

(15) As best illustrated in FIGS. 1 through 12, the valve assembly 10 generally comprises a tube 12, which configured to be inserted between and attached to an inlet pipe 14 for a shower enclosure 16 and a shower head 18. The shower head 18 is in fluidic communication with the inlet pipe 14. The tube 12 has a first end 20, which is internally threaded, and a second end 22, which is externally threaded. The first end 20 and the second end 22 are complementary to external threads on the inlet pipe 14 and internal threads of the shower head 18, respectively. The tube 12 thus can be threadedly attached to both the inlet pipe 14 and the shower head 18.

(16) A valve 24 is positioned in and is rotationally attached to the tube 12 and is configured to regulate a flow of water through the tube 12. The valve 24 may comprise a ball valve 26, as shown in FIGS. 3 and 4, a butterfly valve, or the like.

(17) A housing 28 is attached to the tube 12. A shaft 30 is attached by a first terminus 32 to the valve 24 and extends through a sidewall 34 of the tube 12 and the housing 28 so that a second terminus 36 of the shaft 30 is external to the housing 28. A rod 38 is attached to and extends from the valve 24 into a recess 40, which extends into an inner surface 42 of the tube 12. The rod 38 is opposingly positioned on the valve 24 relative to the shaft 30 and is rotatable within the recess 40. The rod 38 thus is positioned to stabilize the valve 24 within the tube 12.

(18) A biaser 44 is positioned in and is attached to the housing 28. The biaser 44 is operationally engaged to the shaft 30 so that the biaser 44 biases the valve 24 to an open configuration. As shown in FIG. 2, the biaser 44 comprises a torsion spring 46. A lever arm 48 is attached to and extends from the second terminus 36 of the shaft 30. A handle 50 is attached to the lever arm 48 distal from the shaft 30. The handle 50 is configured to be grasped in a hand of a user, positioning the user to move the handle 50 from a first position to a second position, thus actuating the biaser 44 to rotate the valve 24 from a closed configuration to the open configuration so that water flows through the tube 12 to the shower head 18.

(19) The handle 50 may comprise a chain 52, as shown in FIG. 6, a bar 54, as shown in FIG. 9, or the like. The bar 54 comprises an upper segment 56, which is rotationally engaged to the lever arm 48, and a lower segment 58, which is selectively extensible from the upper segment 56. A plurality of holes 60 is positioned in the upper segment 56. A pin 62, which is spring loaded, is engaged to the lower segment 58 and is depressible to allow extension and retraction the lower segment 58. The pin 62 is positioned to extend into a respective hole 60 to fixedly position the lower segment 58 relative to the upper segment 56.

(20) In one configuration, as shown in FIG. 6, the valve assembly 10 comprises a hook 64, which is configured to be mountable to a wall 66 of the shower enclosure 16 below the inlet pipe 14. The hook 64 is positioned to selectively hook the chain 52 to fixedly position the handle 50 in the first position with the valve 24 in the closed configuration, as shown in FIG. 7.

(21) In another configuration, as shown in FIGS. 10 and 11, a cogwheel 68 is positioned in the housing 28 and is attached to the shaft 30. The cogwheel 68 comprises four cogs 70, which are evenly spaced around a circumference 76 of the cogwheel 68, as shown in FIG. 12. A pawl 72 is engaged to an inner facet 74 of the housing 28 and is positioned to selectively engage a respective cog 70 as the cogwheel 68 is rotated upon the user pulling the handle 50. Each movement of the handle 50 rotates the cogwheel 68 by 90°, with the valve 24 being alternately positioned in the open configuration and the closed configuration. While not shown in the Figures, the present invention anticipates the pawl 72 being rotationally engaged to the housing 28 and the valve assembly 10 comprising a release trigger. The release trigger would be engaged to the housing 28 and operationally engaged to the pawl 72 so that triggering of the release trigger would allow counter rotation of the cogwheel 68 concurrent with rebounding of the torsion spring 46.

(22) In use, the tube 12 is inserted between and attached to the inlet pipe 14 and the shower head 18. The hook 64 is mounted to the wall 66 of the shower enclosure 16 below the inlet pipe 14 so that the chain 52 can be hooked to it to fix the valve 24 in the closed configuration. To start a flow of water to the shower head 18, the chain 52 is simply disengaged from the hook 64, thereby allowing the biaser 44 to bias the valve 24 to the open configuration so that water flows through the tube 12 to the shower head 18.

(23) With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

(24) Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
