Water-proof keyboard
First Claim
1. A liquid damage resistant keyboard assembly comprising:
- (a) a seat having formed therein a plurality of through holes, said seat including at least one hollow sleeve portion protruding therefrom disposed about at least one of said through holes;
(b) a circuit unit coupled to said seat;
(c) an elastic body having a plurality of resiliently deflectable controlling hat formations substantially overlaying said circuit unit;
(d) an upper cover substantially enveloping an upper portion of said elastic body for catching and guiding liquid received thereby to drain through at said least one of said through holes of said seat, said upper cover having formed therein at least one recessed groove portion, said at least one recessed groove portion defining a sidewall section for retaining the liquid, said sidewall section having formed therein a laterally recessed hollow drain tube region defining a downwardly extending drain hole in open communication with said at least one of said through holes of said seat, said hollow drain tube region engaging said at least one hollow sleeve of said seat.

Abstract
A water-proof keyboard, wherein proper grooves are installed on the upper cover of the keyboard, and a plurality of drain holes are installed on the front edge of each groove. The drain holes are penetrated to the bottom of the upper cover and drain tubes are connected therebelow. A plurality of sleeves with respect to the drain tubes are installed on the seat of the keyboard. Within each sleeve is formed with a respective through hole each drain tube inserts into the respective through hole within the sleeve. In the water-proof keyboard of the present invention, the liquid flowing into the keyboard may drain out rapidly so that the liquid flowing into the circuit unit can be prevented effectively. Therefore, the circuit will not short or destroyed.
