Abstract

Described below is a methodology to provide a vibration free hard drive mount in a confined computer chassis such as a thin client or network computer. Use is made of a unique comformable interference fit to provide a cost efficient and easy to assemble means of mounting the hard drive in a rigid, solid manner. The method disclosed minimizes the space used to provide the required support while also minimizing the number of mechanical fasteners required. As shown in Fig. 1, the technique described is comprised of only two functional parts: the system chassis (10) and the hard drive bracket (20). Initially the hard drive (30) is attached to the drive bracket typically with screws at the traditional locations. The two tabs (21) designed into the hard drive bracket engage the two respective lanced openings 11), shown in detail in Fig. 2, on the rear wall of the system chassis (10). For ease of assembly, a slight angle of typically 20 degrees provides clearance between the lanced chassis openings (11) and the tabs (21) on the hard drive bracket (20). As the drive bracket (20) is rotated into its final location (depicted by arrows in Fig. 1), the orthogonal clearance between the chassis flap (12) and the drive bracket tabs (21) is reduced, and once in place, becomes a slight interference fit. Once the tabs (21) are "leveraged" against the lanced chassis flaps (12), the two drive bracket mounting screws (not shown) are assembled. The interference fit, together with the two drive bracket mounting screws, fixes the hard drive bracket at the four corners horizontally, vertically, and rotationally, using only the two drive bracket mounting screws. The solution disclosed here and depicted in the figures provides an easy to assembly condition initially due to the larger gap clearances, yet holds the hard drive securely after assembly, with no mechanical deadband or system vibrational resonance. This technique can be adapted to any system hardware chassis that includes a similar chassis frame and hard drive mounting bracket.

Method for Mounting A Hard Drive In A Thin Client Computer

Described below is a methodology to provide a vibration free hard drive mount
in a confined computer chassis such as a thin client or network computer. Use
is made of a unique comformable interference fit to provide a cost efficient
and easy to assemble means of mounting the hard drive in a rigid, solid
manner. The method disclosed minimizes the space used to provide the required
support while also minimizing the number of mechanical
fasteners required.

      As shown in Fig. 1, the technique described is comprised of only two
functional parts: the system chassis (10) and the hard drive bracket (20).
Initially the hard drive (30) is attached to the drive bracket typically with
screws at the traditional locations. The two tabs (21) designed into the hard
drive bracket engage the two respective lanced openings 11), shown in detail
in Fig. 2, on the rear wall of the system chassis (10). For ease of assembly,
a slight angle of typically 20 degrees provides clearance between the lanced
chassis openings (11) and the tabs (21) on the hard drive bracket (20).

      As the drive bracket (20) is rotated into its final location (depicted
by arrows in Fig. 1), the orthogonal clearance between the chassis flap (12)
and the drive bracket tabs (21) is reduced, and once in place, becomes a
slight interference fit. Once the tabs (21) are "leveraged" against the
lanced chassis flaps (12), the two drive bracket mounting screws (not shown)
are assembled....
