Hidden pivot attachment for showers and method of making same
A water supply attachment is a spherically-shaped pivot attachment having a hollow passage extending between its opposing ends that includes a threaded portion for coupling to water supplies. The water supply attachment can be a hidden pivot attachment usable in various shower assemblies. The hidden pivot attachment may be used in combination with a seal cup and an attachment nut, such that the hidden pivot attachment closely fits within the void spaces of the seal cup and attachment nut, enabling the hidden pivot attachment to form a seal with the seal cup.
1. A water supply attachment comprising:
a generally spherically shaped pivot attachment having a main body defining a hollow passageway therethrough and defining opposing ends with a longitudinal axis extending between the opposing ends;
a plurality of adjacent ribs extending radially outwardly from the main body on opposite sides of the main body, substantially longitudinally along a length of the main body and extending substantially between one of the opposing ends to the other of the opposing ends, each of the plurality of adjacent ribs defining an outer edge;
an internal threaded portion extending along a portion of the hollow passageway from one end of the opposing ends;
an inner rib positioned between at least two adjacent ribs of the plurality of adjacent ribs, the inner rib extending from one end of the at least two adjacent ribs along a portion of a length of each of the at least two adjacent ribs and spaced radially inward from the outer edge of the at least two adjacent ribs, the inner rib terminating at a shoulder substantially perpendicular to the longitudinal axis;
wherein the shoulder is located at a position along the length of the main body corresponding to a terminal end of the internal threaded portion.
2. The water supply of claim 1 , wherein the outer edges of each of the plurality of ribs define the spherical shape of the pivot attachment.
3. The water supply attachment of claim 1 , wherein the main body of the pivot attachment further includes an annular ring defined therein, wherein the annular ring is adjacent to one end of the opposing ends and is concentric with the one end of the opposing ends.
4. The water supply attachment of claim 3 , wherein the pivot attachment further includes an annular circumferential protrusion extending from the main body concentrically with the annular ring, wherein the annular circumferential protrusion is configured to receive a O-ring.
5. The water supply attachment of claim 1 , wherein the main body of the pivot attachment further includes at least one planar surface.
6. The water supply attachment of claim 5 , wherein the at least one planar surface further includes a first planar surface positioned on a first side of the pivot attachment and a second planar surface positioned on a second side of the pivot attachment, wherein the passageway is positioned between the first planar surface and the second planar surface.
7. The water supply attachment of claim 6 , wherein the pivot attachment further includes
a first surface rib extending longitudinally along a portion of the length of the main body, and the first surface rib substantially bisects the first planar surface; and
a second surface rib extending longitudinally along a portion of the length of the main body, and the second surface rib substantially bisects the second planar surface.
