Mechanism for securing an add-in module in a computer device

An add-in module for a computer device, the add-in module comprising:

• a housing having an outer shell defining at least two open opposing sides, the housing holding a plurality of peripheral components;
• and
• two input/output brackets each disposed over one of the opposing open sides, at least one of the two input/output brackets connected to a lever and slider mechanism, wherein the lever and slider mechanism includes:
• a base connected to the at least one of the two input/output brackets,
• a wedge slider connected to the at least one of the two input/output brackets and disposed immediately below the base, the wedge slider having a wedged end protrusion,
• a lever connected to the base and coupled to a gear, the lever rotatable from a first position to a second position and from the second position to the first position,
• a geared bar connected to the base and operably coupled to the gear, the geared bar having an angled end abutting and in substantial contact with the wedged end protrusion, and
• a spring disposed between the wedge slider and an outer surface of the input/output bracket, the spring biasing the wedge slider away from the outer surface of the input/output bracket,
• wherein rotating the lever from the first position to the second position causes the gear to engage the geared bar causing the geared bar to move vertically in a first direction, thereby allowing movement along the contact between the angled end of the geared bar and the wedged end protrusion of the wedge slider such that the spring expands biasing the wedge slider away from the bracket and allowing the wedge slider to engage an opening in a mounting panel.
