The outer positioning members, the frame, the brackets, the inner positioning members, and the hard disk are threadedly secured together.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to shockproof hard disks and more particularly to the hard disk of an industrial computer having an improved shock absorbing mechanism.
2. Description of Related Art
It is known that an industrial computer is operated in a strong shock environment. Hence, a useful time of the hard disk of the industrial computer will be shortened significantly if its shock absorbing capability is insufficient. A hard disk of the industrial computer having a well known shock absorbing mechanism is shown in FIG. 1. The shock absorbing mechanism is a suspension type. The shockproof hard disk assembly comprises an inner frame A for receiving a hard disk 1, an outer frame B coupled to the computer case, and a pad 3 filled out between the frames A and B. By configuring as above, strength of shock, jarring or the like generated by a running industrial computer and transmitted to the hard disk 1 will be greatly reduced. However, the prior art suffered from a disadvantage. For example, the provision of the inner and outer frames A and B will greatly reduce available interior space of the computer. Thus, the need for improvement still exists.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a compact shock absorbing mechanism for a hard disk of a computer, comprising a parallelepiped frame having a forward opening for permitting the hard disk to insert into, the frame including, at either side, two first holes, two second holes between the first holes, and two first apertures between the second holes; two side brackets of a section of substantially n, each bracket being threadedly secured to the hard disk and including, at an outer side, two spaced indentations aligned with the first holes, two vertical, elongate slots between the indentations, and two second apertures between the slots; two pairs of barbell shaped pads, each of the pads including two enlargements at ends and an intermediate neck disposed in the slot; two elongate, inner positioning members each including two end stop members each for fastening the inner enlargement of the pad, and two third apertures between the stop members; two elongate, outer positioning member each including two end positioning members each for fastening the outer enlargement of the pad disposed in the second hole, and two fourth apertures between the positioning members; and a plurality of fasteners driven through the fourth, the first, and the second apertures into the third apertures for fastening the outer positioning members, the frame, the brackets, and the inner positioning members together.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a hard disk having a conventional shock absorbing mechanism;
FIG. 2 is an exploded view of a hard disk incorporating a compact shock absorbing mechanism according to the invention;
FIG. 3 is an assembled view of the hard disk assembly with the frame removed; and
FIG. 4 is a cross-sectional view taken along line a—a of FIG. 3.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 2, 3, and 4, there is shown a compact shockproof hard disk assembly constructed in accordance with the invention. The shockproof hard disk assembly comprises a 3.5′′ hard disk 1 having two apertures 11 at either side, and a parallelepiped frame 6 having a forward opening for permitting the hard disk 1 to insert into, the frame 6 including, at either side, two spaced, circular holes 62, two inverted teardrop shaped holes 63 between the holes 62, and two apertures 61 between the holes 63. The shockproof hard disk assembly further comprises, at its either side, a metal bracket 2 having a section of substantially n, the bracket 2 including two spaced apertures 21 at an inner side, two spaced indentations 22 at an outer bottom edge, the indentations 22 being aligned with the holes 62 so as to facilitate the bracket 2 to secure to the hard disk 1, two vertical, elongate slots 23 between the indentations 22, and two apertures 24 between the slots 23; two barbell shaped pads 3 each having two enlargements at ends and an intermediate neck disposed in the slot 23; an elongate, inner positioning member 4 including two end stop members 42 each for fastening the inner enlargement of the pad 3, and two apertures 41 between the stop members 42; an elongate, outer positioning member 5 including two end positioning members 52 each for fastening the outer enlargement of the pad 3 disposed in the hole 63, and two apertures 51 between the positioning members 52; and two sets of a plurality of fasteners (e.g., screws) 7 in which one inner set of the fasteners 7 are driven through the apertures 21 into the apertures 11 for fastening the bracket 2 and the hard disk 1 together, and the other outer set of the fasteners 7 are driven through the apertures 51, 61, and 24 into the apertures 41 for fastening the outer positioning member 5, the frame 6, the bracket 2, and the inner positioning member 4 together.
Note that the assembly of the invention can be done by either of two procedures as below. The first procedure comprises assembling the brackets 2, the pads 3, the inner positioning members 4, the outer positioning members 5, and the frame 6 together, and fastening the hard disk 1 and the brackets together by means of the fasteners 7 in response to aligning the holes 62 with the indentations 22. The second procedure comprises assembling the hard disk 1, the brackets 2, the inner positioning members 4, the pads 3, and the frame 6 together, and assembling the outer positioning members 5 and the pads 3 at the holes 63 of the frame 6.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
