Computer data drive locking device

Claim 2

A computer data drive locking device for a computer having a slotted data storage or receiving access member and having a chassis surrounding the member, where the chassis has a front opening, comprising: (a) a bezel dimensioned to cover the front opening of the chassis and defining a slot, (b) mounting means for attaching said bezel to the chassis, (c) a reinforced lock-plug receptacle formed in and extending through said bezel, said receptacle containing an elongated groove, (d) a key-actuated lock-plug seated in said receptacle and capable of rotation relative to said receptacle, said lockplug containing an elongated projection corresponding to said groove where said projection and groove restrict the rotation of said lock to a preselected limit and further comprising lug means on said bezel to restrict rotation of said locking bar to the preselected limit, (e) a locking bar connected to said lock-plug and capable of movement between a slot-blocking position and a slotunblocking position, said locking bar being located behind said bezel, (f) where actuating said lock-plug moves said locking bar to the blocking position to block said bezel slot and the slotted access member of the computer to prevent introduction of articles to or removal of articles from the slotted access member.

Claim 3

A locking device according to claim 1 where said lock-plug includes a shaft having a noncircular geometric cross-section which extends behind said bezel and said locking bar possesses an aperture having a corresponding geometric cross-section where said locking bar is attached to said shaft through said aperture and secured to the shaft.

Claim 4

A locking device according to claim 2 where said locking bar is dimensioned to block the central portion of the slot behind said bezel.

Claim 5

A locking device according to claim 3 where said locking bar includes a computer chassis engaging element which engages the chassis when said locking bar is in the blocking position.

Claim 6

A computer disk drive locking device for a computer featuring an open front housing and a slotted disk drive, comprising: a molded bezel dimensioned to cover the housing front for snap fitting to the housing, said bezel having a slot for overlying the slotted disk drive, at least one reinforced upper hook formed proximate to the upper portion of the bezel for engaging the border of the computer housing front opening, at least one elongated hook formed proximate to the lower portion of the bezel engaging the computer housing, and a reinforced receptacle for seating a rotatable lock extending through the bezel, said receptacle including at least one elongated axial groove; a rotatable lock dimensioned to be contained in said receptacle, said lock including a rotatable shaft extending beyond said bezel, said shaft having a noncircular cross-section, said lock having at least one axially, disposed projection for coacting with said axial groove to limit the rotation of said lock to a predetermined range of angles, and a rotatable locking bar attached to said shaft in a manner to restrict rotation of said bar to the predetermined range of angles where the locking bar is movable between a slot-blocking position and a slotunblocking position, said locking bar including a hook member for engaging the computer housing when in the slotblocking position.

Claim 7

A computer disk drive locking device for a computer featuring an open front housing and a slotted disk drive, comprising: a molded bezel dimensioned to cover the housing front for snap fitting to the housing, said bezel having a slot for overlying the slotted disk drive, at least one reinforced upper hook formed proximate to the upper portion of the bezel for engaging the border of the computer housing front opening, at least one elongated hook formed proximate to the lower portion of the bezel engaging the computer housing, and a reinforced receptacle for seating a rotatable lock extending through the bezel, said receptacle including at least one elongated axial groove; a rotatable lock dimensioned to be contained in said receptacle, said lock including a rotatable shaft extending beyond said bezel, said shaft having a noncircular cross-section, said lock having at least one axially, disposed projection for coacting with said axial groove to limit the rotation of said lock to a predetermined range of angles, and a rotatable locking bar attached to said shaft in a manner to restrict rotation of said bar to the predetermined range of angles where the locking bar is movable between a slot-blocking position and a slotunblocking position, said locking bar including a hook member for engaging the computer housing when in the slotblocking position.

Claim 8

A locking device according to claim 5 where said locking bar is dimensioned to block the central portion of the slot behind said bezel.
