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.

2. The fastening mechanism of claim 1, wherein the slide has an upper surface and a lower surface, the slide channel having a downward channel surface and an upward channel surface, when the fastening means engaged with the fastening seat, the upper surface contact the downward channel surface and the lower surface contact the upward channel surface.

3. The fastening mechanism of claim 1, wherein the housing chamber further has a front retainer, when the fastening means engaged with the fastening seat, the elastic element pressing the front retainer with one end and pressing the stopping flange with another end.

4. The fastening mechanism of claim 1, wherein the second fastener is a fastening trough and the first fastener is a protrusive key mating against and engageable with the fastening trough to enable the keyboard module fastening to the computer casing.

5. The fastening mechanism of claim 1, wherein the second fastener is a protrusive key and the first fastener is a fastening trough mating against and engageable with the protrusive key to enable the keyboard module fastening to the computer casing.

6. The fastening mechanism of claim 1, wherein the slides and stopping flange are made of same material as the base board, and are formed by punching process.

7. The fastening mechanism of claim 1, wherein the fastening means is made of plastic material and is formed by injection forming process.

8. The fastening mechanism of claim 1, wherein the keyboard module has pseudo keys or insert slots located at the edges where the fastening means are absent for engaging with the computer casing.

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

10. The fastening mechanism of claim 9, each of the slides having an upper surface and a lower surface respectively, each of the slide channels having a downward channel surface and an upward channel surface, when the fastening means engaged with the fastening seat, the upper surface contact the downward channel surface and the lower surface contact the upward channel surface.

11. The fastening mechanism of claim 10, wherein the slide has a third fastener and the slide channel has a fourth fastener and a fifth fastener, when the fastening means is moved to the first position, the third fastener engaged with the fourth fastener; when the fastening means is moved to the second position, the third fastener engaged with the fifth fastener.

12. The fastening mechanism of claim 11, wherein the third fastener is a bulged/dented spot located at the upper surface of the slide, and the fourth and fifth fastener are dented/bulged spots located at the downward channel surface of the slide channel mating against the bulged/dented spot of the third fastener.

13. The fastening mechanism of claim 11, wherein the third fastener is a bulged/dented spot located at the lower surface of the slide, and the fourth and fifth fastener are dented/bulged spots located at the upward channel surface of the slide channel mating against the bulged/dented spot of the third fastener.

14. The fastening mechanism of claim 10, wherein the slide channel has a third fastener and the slide has a fourth fastener and a fifth fastener, when the fastening means is moved to the first position, the third fastener engaged with the fourth fastener; when the fastening means is moved to the second position, the third fastener engaged with the fifth fastener.

15. The fastening mechanism of claim 14, wherein the third fastener is a bulged/dented spot located at the upward channel surface of the slide channel, and the fourth and fifth fastener are dented/bulged spots located at the lower surface of the slide mating against the bulged/dented spot of the third fastener.

16. The fastening mechanism of claim 14, wherein the third fastener is a bulged/dented spot located at the downward channel surface of the slide channel, and the fourth and fifth fastener are dented/bulged spots located at the upper surface of the slide mating against the bulged/dented spot of the third fastener.

17. The fastening mechanism of claim 9, wherein the body has a horizontal bulged ridge located at the top surface thereof for moving the fastening means forwards or rearwards.

18. The fastening mechanism of claim 9, wherein the body has a second fastener located at a front end thereof in a form of a fastening trough which has a bulged spot located therein, the first fastener of the computer casing corresponding to the fastening tough having a protrusive key which has a dented spot mating and engaged with the bulged spot when the fastening trough engaged with the protrusive key to enable the keyboard module fastening to the computer casing securely.
