Top-mount twist-on faucet
View Patent ↗A top-mount faucet assembly includes a coupling mounted on a counter that selectively couples a faucet thereto. The counter coupling has a disc-shaped collar with two keepers and a land for selectively locking the faucet. The land has a v-shaped part and a n-shaped part. The faucet has a main valve body with a locking assembly. To couple the faucet to the counter coupling, the main valve body is placed over the coupling and turned clockwise so that slots align with the keepers to fix the faucet axially to the coupling. As the faucet rotates clockwise, the locking assembly rides along the v-shaped part until captured by the n-shaped part to lock the faucet in place rotationally. To uncouple the faucet from the coupling, a button is pushed so that the locking assembly moves radially inward out from the n-shaped part, then the faucet is turned counter-clockwise.
1. A top-mount twist-on faucet assembly comprising:
a counter coupling having: a collar for mounting to a counter; a lower portion depending from the collar for coupling to a water source; an upper portion extending from the collar for coupling to a faucet; and at least one land having a v-shaped first part and a second n-shaped part; and
the faucet having: a main body defining an axial bore for engaging the counter coupling and a release assembly passageway transverse to the bore; a dispensing tube extending from the main body; and a locking assembly for coupling to the at least one land to selectively couple the faucet to the counter coupling, wherein the locking assembly includes a release button extending radially outward and a pin depending from the passageway of the main body and coupled to the release button such that upon depression of the release button, the depending pin moves radially inward,
wherein
to couple the faucet to the counter coupling, the main body is placed over the upper portion and turned clockwise so that the pin rides along an outside of the first v-shaped part until the depending pin is captured by nesting in the second n-shaped part, and
to uncouple the faucet from the counter coupling, the release button is pushed so that the depending pin moves out from nesting in the second n-shaped part, then the main body is turned counter-clockwise so that the pin rides again along the outside of the first v-shaped part and the faucet is freed from the upper portion.
2. A top-mount twist-on faucet assembly as recited in claim 1 , wherein the collar is disc-shaped.
