Abstract:
A key structure of a computer keyboard, comprising:(a) a cap member having a top surface and side walls extending from said top surface of said cap member;(b) a post member extending axially from said top surface of said cap member within a periphery of said side walls, said post member being formed of a pair of opposing first side walls and of a pair of opposing second side walls,a pair of first resilient members, each formed on a respective one of said pair of first side walls of said post member and extending outwardly from an outer surface thereof,a pair of second resilient members, each formed on a respective one of said pair of second side walls of said post member, each said second resilient member defining an elongated slot extending along said respective second side wall of said post member and further having a protrusion member formed at a lower end of said elongated slot and extending outwardly therefrom; and(c) a guide channel formed in the keyboard,said guide channel having a pair of opposing third side walls and a pair of opposing fourth side walls arranged to form an internal path of said guide channel, anda pair of stop blocks, each stop block being respectively formed on an inside surface of said fourth side walls of said guide channel;said post member being slidably received within said internal path of said guide channel, said first resilient members resiliently engaging with an inner surface of said third side walls, and said protrusion member of said second resilient members resiliently contacting a respective one of said stop blocks on said fourth side walls, thereby stabilizing the motion of said post member within said guide channel, and thereby reducing unwanted excessive interaction between said key structure and the keyboard.
