Sealed computer terminal keyboard.

摘要

A computer terminal keyboard (11) is sealed by a molded elastomeric top cover (14), shaped to conform to the housing and keys (34) of the keyboard, and a bottom cover (16) shaped to enclose the base of and secure the top cover around its periphery to the keyboard housing. The top cover (14) is shaped to provide a substantially planar surface on the top plate with elevated individual key covers (74) integrally formed in the top cover. Portions 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 (14) immediately adjacent and between the individual key covers (74) 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 (14) is planar so that spilled liquid and debris are easily wiped or brushed away from around and between the key covers. The bottom cover (16) is formed of a rigid material and has edges shaped to mate snugly against wraparound flanges (56) on the periphery of the top cover. The bottom cover (16) is securd by screws (60) in existing screw holes (62) in the underside of the keyboard housing.
