1. An integrated latch apparatus for securing and releasing computer equipment from a chassis, the apparatus comprising:
a support bracket including a first lateral structure;
a mounting bracket secured to the support bracket;
a rotating shaft secured to the support bracket;
a sliding plate including a latching extension, the sliding plate being disposed between the support bracket and the mounting bracket;
a handle including a second lateral structure at a rotating end of the handle, the handle secured at the rotating end to the support bracket about the rotating shaft, the rotating end of the handle including one or more nudging extensions;
a torsion spring disposed on the rotating shaft such that the torsion spring biases the first lateral structure of the support bracket against the second lateral structure of the handle such that the handle is in an open position when the torsion spring is extended toward an equilibrium state and in a closed position when the torsion spring is biased toward a fully compressed state; and
a pair of compression springs positioned between the sliding plate and the support bracket such that the compression springs bias the latching extension of the sliding plate away from the support bracket such that the handle is in a closed position when the compression springs are extended toward an equilibrium state and in an open position when the compression springs are biased toward a fully compressed state,
wherein the one or more nudging extensions of the handle directly engage the sliding plate through one or more corresponding slots in the sliding plate to laterally move the sliding plate when the handle is rotated from the open position to the closed position, thereby moving the latching extension away from the support bracket to engage the chassis as the handle is rotated to the closed position, the one or more corresponding slots being through-holes,
wherein rotating the handle from the open position to the closed position causes the one or more nudging extensions to extend past the sliding plate, wherein the one or more nudging extensions do not extend past the sliding plate while the handle is in the open position.
