Keyboard assembly

Coupling apparatus comprising

• first and second plate-like members to be coupled together,
• said first member having a top surface for supporting a keyboard and a bottom surface,
• said second member having a top surface for supporting a key pad and a bottom surface,
• the bottom surface of said first member carrying two spaced-apart coupling plates which are parallel to each other and are spaced above the bottom surface of said first member to provide a space between said coupling plates and said bottom surface,
• the body of said first member between said coupling plates including a flexible plate having a raised locking tab which extends above the bottom surface of said first member,
• the bottom surface of said second member carrying two spaced-apart coupling plates which are parallel to each other and are spaced above the bottom surface of said second member to provide a space between said coupling plates and said bottom surface,
• the body of said second member between said coupling plates including a flexible plate having a raised locking tab which extends above the bottom surface of said second member, and
• a rigid plate-like coupling member having first and second ends and a first slot at said first end and a second slot at said second end,
• said slots having substantially the same shape and area as said raised locking tabs,
• said rigid plate-like coupling member being adapted to have said first end inserted under the coupling plates of said first member with the locking tab thereof seated in said first slot to lock the coupling member in place,
• said rigid plate-like coupling member being adapted to have said second end inserted under the coupling plates of said second member with the locking tab thereof seated in said second slot to lock the coupling member in place and thereby to secure said coupling member to said first and second members.
