ABSTRACT:
Articulating faucets have segments connected by a plurality of movable joints. Each joint includes a pair of ceramic mating disks arranged in face to face contact, but able to rotate relative to each other when sufficient force is applied. A wave spring helps keep the disks in constant contact, and rubber spheres press against opposing surfaces of the ceramic disks to produce shear forces to keep the joint stable. In the faucet water passes through the joint by means of a tube or a hollow banjo bolt sealed from the joint. The faucet can therefore direct water to a wide variety of positions, without the need for a side spray, and while reducing the risk of joint leakage.
