US 6,672,796 B2 · Fastening mechanism for detachable keyboard modules

Abstract

A fastening mechanism for detachable keyboard modules with the keyboard module consists of at least one fastening seat. The fastening seat engages with a fastening means. The keyboard module is fastened to a computer casing through the fastening means. The fastening means includes a body, two slide channels and an elastic element. The body has a second fastener located at a front end and a housing chamber located at a rear end. The two slide-channels are located at two sides of the body to form a slidable coupling with two slides which located at two sides of the fastening seat. The elastic element is restricted between the housing chamber and a stopping flange which located at a rear end of the fastening seat. The elastic force of the elastic element may push the fastening means forwards to enable a second fastener located at the front end of the body to engage with a first fastener located at the computer casing thereby to enable the keyboard module fastening to the computer casing. When the fastening means is moved rearwards, the second fastener is separated from the first fastener thereby enabling the keyboard module detached from the computer casing.

A fastening mechanism for detachable keyboard modules for fastening a keyboard module which has a base board to a first fastener located on a computer casing, the fastening mechanism comprising:

at least one fastening seat located at an edge of the base board, and having a closed end, the fastening seat further having:
slides disposed on two sides of the fastening seat each having a ramp section tilted downwardly at a rear end thereof;
a stopping flange located at the closed end;
and
at least one fastening means slidably engaged with the fastening seat, having:
a body having a second fastener located at a front end thereof and a housing chamber located at a rear end thereof;
slide-channels located at two sides of the body slidably engaged with the slides and having a rear retainer located at a rear end thereof, such that, when the fastening means engages the fastening seat, the rear retainer is blocked by the ramp section preventing the fastening means from sliding out of the fastening seat;
and
an elastic element being restricted between the housing chamber and the stopping flange, and having elastic force to move the fastening means forwards to enable the second fastener engaging with the first fastener thereby fastening the keyboard module to the computer casing, when the fastening means receiving force and moved rearwards, the second fastener being separated from the first fastener and making the keyboard module separated from the computer casing.
