Pin lock

A fastening mechanism, comprising:

• a pin having a head;
• a shank coupled to said head at a first end of said shank;
• a metallic pin-lock having a base portion coupled to a resilient pin-engaging portion;
• said shank having a circumferentially-formed notch at a second end, said notch being adapted to receive said resilient pin-engaging portion;
• a spring coupled to said base portion of said metallic pin-lock and to a mobile phone housing;
• a retainer housing said fastening mechanism;
• wherein, upon insertion of said pin into said pin-lock, said pin is adapted to move said resilient pin-engaging portion a predetermined distance until said resilient pin-engaging portion engages said circumferentially-formed notch;
• and
• wherein said pin-lock is adapted to be removed from said pin via a magnet attracting at least a portion of said pin-lock away from said pin.

A fastening mechanism, comprising:

• a pin having a head;
• a shank coupled to said head at a first end of said shank;
• a non-metallic pin-lock having a base portion coupled to a resilient pin-engaging portion;
• said shank having a circumferentially-formed notch at a second end, said notch being adapted to receive said resilient pin-engaging portion;
• a coupling member coupled to said base portion of said non-metallic pin-lock and to a mobile phone housing;
• a retainer housing said fastening mechanism;
• wherein, upon insertion of said pin into said pin-lock, said pin is adapted to move said resilient pin-engaging portion a predetermined distance until said resilient pin-engaging portion engages said circumferentially-formed notch;
• and
• wherein said pin-lock is adapted to be removed from said pin via interaction between a first pre-determined force between said pin and said pin lock, a second predetermined force between said pin lock and said retainer, said retainer being adapted to resist said first predetermined force, a third predetermined force between said retainer and said pin lock, and a fourth predetermined force between said coupling member and said retainer.
