  • Patent number: 7443667
    Abstract: A mounting apparatus for holding a storage device with a plurality of mounting holes thereof. The mounting apparatus includes a bracket for accommodating the storage device therein and a fastener. The bracket includes a first sidewall. The first sidewall has a pair of installing plates and a securing portion opposite to the pair of installing plates. A plurality of through holes is defined between the pair of installing plates and the securing portion, corresponding to the mounting holes. The fastener has a pivot end pivotally attached to the pair of installing plates and a free end forming a locking portion engagable with the securing portion. A plurality of locking pegs projects from the fastener. When the locking pegs are passed through the through holes and inserted into the mounting holes of the storage device, the storage device is secured in the bracket.
