Abstract
Abstract The purpose of the present invention is to provide a cover for a hard disk drive which can prevent the outflow of a damping resin material and the loosening of a screw fixing the cover to a storage-enclosing case. To attain this purpose, the cover of the present invention is fabricated of a laminated plate with a damping resin member closely inserted between an inner plate and an outer plate of metal, to cover a storage device case by fastening with screws at tapped holes equipped on the laminated plate, wherein a sealing member is installed on the inner plate for sealing between the laminated plate and the case; the marginal portion of the laminated plate and the inner wall of the tapped hole are formed to have a closed structure by bending the inner plate and/or the outer plate to attain a direct contact with each other, so as to prevent the damping resin material from flowing out; and the inner wall of the tapped hole of the closed structure works as a stopper for hooking the head of the screw inserted through the tapped hole.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
A cover for a hard disk drive fabricated of a laminated plate with a damping resin material closely inserted between an inner plate and an outer plate of metal, to cover a case enclosing a storage device by fastening with screws inserted through tapped holes equipped on the laminated plate, wherein: a sealing member is installed on the inner plate for sealing between the laminated plate and the case; the marginal portion of said laminated plate and the inner wall of the tapped hole are formed to have closed structures respectively by bending the inner plate and/or the outer plate to attain a direct contact with each other, so as to prevent the damping resin material from flowing out; and the inner wall of the tapped hole of the closed structure works as a stopper for hooking the head of the screw inserted through the tapped hole.
Claim 2
Dependent Claim
147 words
A cover for a hard disk drive fabricated of a laminated plate with a damping resin material closely inserted between an inner plate and an outer plate of metal, to cover a case enclosing a storage device by fastening with screws inserted through tapped holes equipped on the laminated plate, wherein: a sealing member is installed on the inner plate for sealing between the laminated plate and the case; the marginal portion of said laminated plate and the inner wall of the tapped hole are formed to have closed structures respectively by bending the inner plate and/or the outer plate to attain a direct contact with each other, so as to prevent the damping resin material from flowing out; and the inner wall of the tapped hole of the closed structure works as a stopper for hooking the head of the screw inserted through the tapped hole.
Claim 3
Dependent Claim
61 words
A cover for a hard disk drive fabricated of a laminated plate with a marginal portion according to claim 1 , wherein the marginal portion of an outer plate, formed by one inward bending and one outward bending at approximately right angles respectively, is overlapped with the marginal portion of an inner plate to attain a directly contact with each other.
Claim 4
Dependent Claim
92 words
A cover for a hard disk drive fabricated of a laminated plate with a marginal portion according to claim 1 , wherein the marginal portion of an outer plate, formed by one inward bending and one outward bending at approximately right angles respectively, overlaps with the marginal portion of an inner plate, and then by one outward bending of the marginal portion of the inner plate, the inner peripheral surface of the bent marginal portion of the inner plate meets the outer peripheral cross section of the end of the outer plate.
Claim 5
Dependent Claim
90 words
A cover for a hard disk drive fabricated of a laminated plate with a peripheral margin according to claim 1 , wherein the marginal portion of an outer plate, formed by one inward bending, one outward bending and another inward bending at approximately right angles respectively, overlaps with the marginal portion of an inner plate so that the inner peripheral surface of the patch formed by the last bending of the marginal portion of the outer plate meets the outer peripheral cross section of the end of the inner plate.
Claim 6
Dependent Claim
65 words
A cover for a hard disk drive fabricated of a laminated plate with a peripheral margin according to claim 1 , wherein the inner peripheral surface of the marginal portion of an inner plate, formed by one outward bending of the marginal portion of the inner plate at an approximately right angle, meets the outer peripheral cross section of the end of an outer plate.
Claim 7
Dependent Claim
65 words
A cover for a hard disk drive fabricated of a laminated plate with a peripheral margin according to claim 1 , wherein the inner peripheral surface of the marginal portion of an outer plate, formed by one inward bending of the marginal portion of the outer plate at an approximately right angle, meets the outer peripheral cross section of the end of an inner plate.
Claim 8
Dependent Claim
71 words
A cover for a hard disk drive having an inner wall of a tapped hole equipped on the cover according to claim 1 , wherein the peripheral margin of a tapped hole of an outer plate, formed by one inward bending and one outward bending at approximately right angles respectively, overlaps with the peripheral margin of an inner plate of the tapped hole so as to directly contact with each other.
Claim 9
Dependent Claim
101 words
A cover for a hard disk drive having an inner wall of a tapped hole equipped on the hard disk drive cover according to claim 1 , wherein the inner peripheral surface of a tubular portion of an outer plate, formed by one inward bending and one outward bending of the peripheral margin of the outer plate of the tapped hole at approximately right angles respectively, meets the outer peripheral surface of a tubular portion of an inner plate, formed by one inward bending of the peripheral margin of an inner plate of the tapped hole at an approximately right angle.
Claim 10
Dependent Claim
82 words
A cover for a hard disk drive having an inner wall of a tapped hole equipped on the cover according to claim 1 , wherein the outer peripheral surface of a tubular portion of an outer plate, formed by one inward bending, one outward bending and another inward bending of the peripheral margin of an outer plate of the tapped hole at approximately right angles respectively, meets the inner surface of the peripheral margin of an inner plate of the tapped hole.
