Abstract
A computer terminal keyboard is sealed by a molded elastomeric top cover, shaped to conform to the housing and keys of the keyboard, and a bottom cover shaped to enclose the base of and secure the top cover around its periphery to the keyboard housing. The top cover is shaped to provide a substantially planar surface on the top plate with elevated individual key covers integrally formed in the top cover. Portitons of the top cover extending over the top face and sides of the keyboard housing are formed in a first thickness sufficient to provide a durable covering. Portions of the top cover immediately adjacent and between the individual key covers, and the sides of the key covers, are formed in a reduced, second thickness to allow for flexure as the keys are depressed. The top surface of the top cover is planar so that spilled liquid and debris are easily wiped or brushed away from around and between the key covers. The bottom cover is formed of a rigid material and has edges shaped to mate snugly against wraparound flanges on the periphery of the top cover. The bottom cover secured by screws in existing screw holes in the underside of the keyboard housing.
