<p>PCT No. PCT/US88/02198 Sec. 371 Date Feb. 28, 1989 Sec. 102(e) Date Feb. 28, 1989 PCT Filed Jun. 30, 1988 PCT Pub. No. WO89/00275 PCT Pub. Date Jan. 12, 1989.A mechanism for covering and protecting operating parts of a mixing faucet that has a bidirectional control lever 10 which extends through an opening in its cover 11 and moves about a single center. A semi-spherical surface 11a of the cover abuts a thin semi-spherical cap 15 having an exterior and interior surface 15a and 15b having the same center of rotation as the lever. The cover is semi-spherical surface substantially corresponds to the semi-spherical cap's interior surface. The semi-spherical cap 15 covers the opening 10 and is able to slide over the semi-spherical surface of the cover due to its identical spherical curvature. Structurally the cap is separate from the control lever and is transverse to it. The cap 15 makes contact with a rim of the window 17 of an outer hood 16. The hood 16 is mounted about the cover 11 and able to slide thereagainst and into the space underneath the hood. Cap 15 and the hood 16 can be economically produced and mounted onto the valve. The cap and hood can be made from plastic materials or molded metallic laminates.</p> |
