Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 147 words
A portable computer and lock combination, comprising: a portable computer comprising a chassis having a hard disk drive compartment and a door for opening and closing said hard disk drive compartment and at least one card receiving slot; and a lock comprising a lock body and locking means disposed at one end of said lock body and a flange disposed about said lock body; said lock being lockingly engageable by said locking means with an opening in said chassis such that when said lock is so engaged said flange prevents cards from being removed from said at least one card receiving slot; and said flange further prevents said door from being opened such that said door is maintained in a closed position. said lock thereby simultaneously securing both said at least one card receiving slot and said disk drive compartment of said computer from unauthorized access thereto.
Claim 2
Dependent Claim 147 words
A portable computer and lock combination, comprising: a portable computer comprising a chassis having a hard disk drive compartment and a door for opening and closing said hard disk drive compartment and at least one card receiving slot; and a lock comprising a lock body and locking means disposed at one end of said lock body and a flange disposed about said lock body; said lock being lockingly engageable by said locking means with an opening in said chassis such that when said lock is so engaged said flange prevents cards from being removed from said at least one card receiving slot; and said flange further prevents said door from being opened such that said door is maintained in a closed position. said lock thereby simultaneously securing both said at least one card receiving slot and said disk drive compartment of said computer from unauthorized access thereto.
Claim 3
Dependent Claim 173 words
A portable computer and lock combination, comprising: a portable computer comprising a chassis having at least one card receiving slot, a drive compartment and door for opening and dosing said drive compartment, said door including a sliding member engageable with said chassis between an open and closed position; and a lock comprising a lock body, locking means disposed at one end of said lock body and a flange disposed about said lock body; said lock being locking engageable by said locking means within an opening in said chassis and a corresponding opening in said sliding member, such that when said lock is so engaged said lock body prevents translation of said sliding member, thereby maintaining said door in said dosed position; and further wherein when said lock is lockingly engaged with said chassis said flange prevents removable components from being removed from said at least one card receiving slot. said lock thereby simultaneously securing both said at least one card receiving slot and said drive compartment of said computer from unauthorized access thereto.
Claim 4
Dependent Claim 173 words
A portable computer and lock combination, comprising: a portable computer comprising a chassis having at least one card receiving slot, a drive compartment and door for opening and dosing said drive compartment, said door including a sliding member engageable with said chassis between an open and closed position; and a lock comprising a lock body, locking means disposed at one end of said lock body and a flange disposed about said lock body; said lock being locking engageable by said locking means within an opening in said chassis and a corresponding opening in said sliding member, such that when said lock is so engaged said lock body prevents translation of said sliding member, thereby maintaining said door in said dosed position; and further wherein when said lock is lockingly engaged with said chassis said flange prevents removable components from being removed from said at least one card receiving slot. said lock thereby simultaneously securing both said at least one card receiving slot and said drive compartment of said computer from unauthorized access thereto.
Claim 5
Dependent Claim 19 words
The combination of claim 2 wherein said flange at least partially obstructs said at least one card receiving slot.
Claim 6
Dependent Claim 39 words
The combination of claim 2 wherein said chassis further comprises means for ejecting a card from said at least one card receiving slot and wherein said flange at least partially obstructs and prevents the actuation of said ejecting means.
Claim 7
Dependent Claim 62 words
The combination of claim 2 wherein said locking means is reciprocatable between a first unlocked position and a second locked position, said chassis opening for receiving said lock body and said sliding member opening registering with said chassis opening allowing passage of said locking means in said first unlocked position and preventing passage of said locking means in said second locked position.
Claim 8
Dependent Claim 145 words
Apparatus for securing removable modular components of a computer, the computer including a chassis for removably housing the components, the apparatus comprising: a door defined in said chassis having a sliding bar which includes a tongue disposed in said chassis, said door for covering at least one said modular component and said tongue being slidably engageable within said chassis between an open and closed position of said door; an aperture defined in said door; a lock receivable in said aperture for locking engagement with said chassis; an aperture defined in said bar for receiving said lock, said door aperture being in alignment with said bar aperture when said door is in said closed position; such that in said locking engagement, said lock is received in both said door and bar apertures, thus preventing said tongue from sliding to said open position, thereby securing said component.
Claim 9
Dependent Claim 145 words
Apparatus for securing removable modular components of a computer, the computer including a chassis for removably housing the components, the apparatus comprising: a door defined in said chassis having a sliding bar which includes a tongue disposed in said chassis, said door for covering at least one said modular component and said tongue being slidably engageable within said chassis between an open and closed position of said door; an aperture defined in said door; a lock receivable in said aperture for locking engagement with said chassis; an aperture defined in said bar for receiving said lock, said door aperture being in alignment with said bar aperture when said door is in said closed position; such that in said locking engagement, said lock is received in both said door and bar apertures, thus preventing said tongue from sliding to said open position, thereby securing said component.
Claim 10
Dependent Claim 134 words
A lock for preventing the removal of cards and modular components from a portable computer, said computer having a drive compartment for housing said modular components and a door for opening and closing said drive compartment, and having a card receiving slot for receiving said cards, said computer further having a chassis containing an opening therein in proximity to both said door and said card receiving slot, the lock comprising: a lock body adapted to be received in said chassis opening; reciprocating locking means disposed at one end of said lock body adapted to be lockingly engaged with the chassis of said portable computer; and a flange disposed about said lock body adapted to simultaneously prevent the removal of said cards from said card receiving slot and said modular components from said drive compartment.
Claim 11
Dependent Claim 134 words
A lock for preventing the removal of cards and modular components from a portable computer, said computer having a drive compartment for housing said modular components and a door for opening and closing said drive compartment, and having a card receiving slot for receiving said cards, said computer further having a chassis containing an opening therein in proximity to both said door and said card receiving slot, the lock comprising: a lock body adapted to be received in said chassis opening; reciprocating locking means disposed at one end of said lock body adapted to be lockingly engaged with the chassis of said portable computer; and a flange disposed about said lock body adapted to simultaneously prevent the removal of said cards from said card receiving slot and said modular components from said drive compartment.
Claim 12
Dependent Claim 17 words
The lock of claim 7, wherein said flange extends beyond the outer perimeter of said lock body.
Claim 13
