Description
COMPUTER PHYSICAL SECURITY DEVICE
This application is divided from Canadian Patent Application Serial Number 2,186,268, filed February 7, 1996.
BACKGROUND OF THE INVENTION
The present invention relates generally to devices for inhibiting the theft of relatively small but expensive pieces of equipment. More specifically, the invention relates to a lock interface for a specially designed slot having predetermined dimensions.
Computers have evolved rather rapidly from large expensive machines usable only by a few, to relatively small, portable machines which are usable by many. In particular, the development of desktop computers with significant processing power has made computers available to the general population. It is now common for college and even high school students to have their own computer, and desktop computers are in wide spread use as word processors and work stations in almost all forms of business. Desktop computers are relatively small and easily transportable, and an undesirable side effect of their proliferation is the fact hat the theft of such computers is a significant problem.
A variety of devices have been developed to inhibit the theft of desktop computers and similar equipment.
Since desktop computer systems involve several components, typically including the computer itself, a separate monitor, keyboard and often a printer, such security systems often employ a cable which attaches each of the components to each other and to a relatively immovable object such as a desk. The principal difficulty in such systems is providing an effective and convenient method for attaching the cable itself to the equipment.
Kensington Microware Limited, assignee of this application, currently provides a security system which is especially designed for use with particular Apple computers. Certain Apple computer components have slots and internal brackets designed to capture a specially designed tab inserted through the slot so that the tab is not removable. While this system is effective for particular types of Apple computers, it does not work for those Apple computer components and other computer brands which do not have the special designed slots and brackets.
It is undesirable to require a computer to have specially designed slots and internal capture brackets because the brackets occupy a significant amount of space in an item of equipment which is intended to be as space efficient as possible. Different items of Apple equipment require different sized slots, meaning that the security mechanism must provide a variety of different sized tabs.
The tabs, once inserted, cannot be removed without damage to the equipment, meaning that the security system cannot be moved from one computer to the other. Even Apple computers with specially designed slots are typically used with peripheral equipment which does not have them, and, the Kensington system provides screws requiring a special screwdriver which replace the screws used to attach the existing communication cables, securing the peripheral equipment to the base computer by preventing unauthorized removal of the communication cables. This last aspect of the system has a drawback in that the peripheral equipment cannot be removed from the base computer without the special screwdriver, which can be lost or misplaced.

This last aspect of the system has a drawback in that the peripheral equipment cannot be removed from the base computer without the special screwdriver, which can be lost or misplaced.
Other vendors provide security systems which are not required to interface directly with special slots and capture mechanisms as provided in certain Apple computers.
For example, Secure-It, Inc., under the trademark "KABLIT", provides a variety of brackets attached to the computer component using existing mounting screws, i.e., screws which are already used to secure items of equipment within the cabinet. Typically, the bracket is apertured so that passage of the cable through the aperture prevents access to the mounting screw and thus prevents removal of the bracket from the equipment. A deficiency of this type of system is that it requires the removal of the existing mounting screw, which may cause some damage to the internal components of the computer. Suitable existing screws are not always available on certain peripherals for convenient attachment of the fastener. For this latter reason, KABLIT
also provides glue-on disks which, unfortunately, are permanently secured to the equipment.
The theft of small but expensive equipment such as desktop computers is a growing problem. Existing devices are simply too inefficient or ineffective, or their app:lication is too limited. As a result, the use of such security systems is rare, computer equipment is typically left unprotected, and it is all too often stolen.

5 Locking spindle 400 is inserted in central cavity 440 with enqagement handle 415 slidably insertable into engaqement slot 445. Anchor spindle 430 is adapted to allow lockinq spindle 400 to move co-axially within anchor cavity 440 towards and away from head portion 475 so as to insert and 10 withdraw lockinq pin 420 and locking pin 425 from locking pin aperture 460 and locking pin aperture 465.
In operation, a user aligns head portion 475 with slot 15 and inserts head portion 475 into slot 15. Aligning locking pin aperture 460 and locking pin aperture 465 with slot 15 mis-aligns head portion 475 with slot 15, thereby enqaqing head portion 475 with inner surface 20 and inhibiting removal of lock interface 65 from computer 5. Subsequent insertion of lockinq spindle 400 into central cavity 440 and insertion of enqaqement handle 415 in engagement slot 445, moves locking spindle 400 co-axially in central cavity 440 towards wall 10 until lockinq pin 420 protrudes through locking pin aperture 460 and into slot 15 and until lockinq pin 425 protrudes through locking pin aperture 465 and into slot 15.
In the preferred embodiment, the size of neck portion 470 toqether with locking pin 420 exceed smaller dimension 42 of slot 15, inhibiting rotation of lockinq spindle 400 and anchor spindle 430 within slot 15, thereby inhibitinq re-aliqnment of head portion 475 with slot 15.
Lockinq a locking mechanism 30 through aperture 410 and aperture 450 maintains the anqaqement of lockinq spindle 400 to anchor spindle 430, and can be used to lock tha computer 5 to a stationary object..
Fiq. 11 illustrates another embodiment of a lock interface 70. Lock interface 70 includes an engaqement member 500. Enqaqement member 500 includes a first laq 505, a second leq 510, a first aperture 515 between first leg 505 and second lag 510, a second aperture 520 between first leq 505 and second leg 510, and a space 525 betwaen first leg 505 and second leg 510. First leg 505 includes a flange 530 at a distal end that is flanged away from second leg 510, and second leg 510 includes a flange 535 at a distal end that is flanqed away from first leg 505. Lock interface 70 also includes a retainer 540. Retainer 540 includes a cavity 545, a spacer 550, and an aperture 555.
Enqagement member 500 is slidably disposed within cavity 545 with spacer 550 beinq fixed in relation to retainer 540. Spacer 550 is small enough to freely slide within space 525, but is larqe enough to inhibit first laq 505 and second leg 510 from being squeezed together as illustrated in Fig.
11. When spacer 550 is located at first aperture 515 or second aperture 520, first leg 505 and second leg 510 can be squeezed together. This squeezed position defines a first position, and the unsqueezed position defines a second position. Fig. 12 is another view of the lock interface in Fig. 11 with first leg 505 and second leq 510 in the first position. When first leq 505 and second leg 510 are in the first position, flange 530 and flanqe 535 are insertable and removable from the slot 15. Fiq. 11 illustrates that when first leq 505 and second leq 510 are in the second position, flange 530 and flanqe 535.are enqaqeable with inner surface 20.
In operation, a user withdraws engagement member 500 from cavity 545 until spacer 550 is located at first aperture 515 (or second aperture 520). Squeezinq first leg 505 and second leq 510 together moves first leg 505 and second leq 510 into the first position, allowinq insertion of flanqe 530 and flange 535 into slot 15. Returning first leq 505 and second leg 51o to the second position allows flange 530 and flange 535 to enqaqe inner surface 20. Subsequent movement of retainer 545 towards wall 10 until retainer 545 abuts wall 10, locates spacer 550 in space 525 but not within first aperture 515 or second aperture 520 and co-aligns aperture 555 with second aperture 520. In the preferred embodiment, locating spacer 550 in space 525 but not within first aperture 515 or second aperture 520, inhibits movinq first leq 505 and second leg 510 into the first position. Locking a locking mechanism 30 through aperture 555 and second aperture 520 maintains the engagement of engagement member 500 with inner surface 20, and can be used to lock the computer 5 to a stationary object.
Fig. 13 illustrates another embodiment of lock interface 75. Lock interface 75 includes an engagement member 600. Engagement member 600 includes a first leg 605, a second leg 610, and a space 615 between first leg 605 and second leg 610. First leg 605 includes a flange 620 at a distal end that is flanged away from second leg 610, and second leg 610 includes a flange 625 at a distal end that is flanged away from first leg 605. Lock interface 75 also includes a spacer 630 having a ramped portion 635, and a spacer mover 635.
Spacer mover 635 includes a housing 640, a rotatable shaft 645, a cam 650, and an aperture 655.
Spacer 630 is slidably disposable within space 615 by the movement of cam 650. When spacer 630 is not disposed between first leg 605 and second leg 610, this default position defines a first position, and when spacer 630 is disposed between first leg 605 and second leg 610 the position defines a second position. Fig. 13 illustrates that when first leg 605 and second leg 610 are in the first position, flange 620 and flange 625 are insertable and removable from the slot 15. Fig. 14 is another view of the lock interface in Fig. 13 with first leg 605 and second leg 610 in the second position. When first leg 605 and second leg 610 are in the second position, flange 620 and flange 625 are engagable with inner surface 20. A ramped portion 635 of spacer 630 is used to smoothly move first leg 605 and second leg 610 from the first position to the second position.
in operation, when first leg 605 and second leg 610 are in the first position, a user inserts flange 620 and flange 625 into slot 15. Rotating rotatable shaft 645 relative to housing 640 causes cam 650 to insert spacer 630 into space 615 which causes first leg 605 and second leg 610 to move into the second position. When first leg 605 and second leg 610 reach the sacond position, flange 620 and flange 625 engage inner surface 20. Locking a locking mechanism 30 through aperture 655 maintains the engagement of engagement member 600 with inner surface 20, and can be used to lock the computer 5 to a stationary object.

In the foregoing specification, the invention has been described with reference to a specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made thereunto without departing from the broader spirit and scope of the invention as set forth in the claims.
Many changes or modifications are readily envisioned, for example, changinq the shape of the slot and the shape of the head portion, adding catches to the engagement members, and changing the shape of the flanges among other changes. The specification and drawings are, accordingly, to be regarded in an illustrative rather than in a restrictive sense.
For example, Secure-It, Inc., under the trademark "KABLIT", provides a variety of brackets attached to the computer component using existing mounting screws, i.e., screws which are already used to secure items of equipment within the cabinet. Typically, the bracket is apertured so that passage of the cable through the aperture prevents access to the mounting screw and thus prevents removal of the bracket from the equipment. A deficiency of this type of system is that it requires the removal of the existing mounting screw, which may cause some damage to the internal components of the computer. Suitable existing screws are not always available on certain peripherals for convenient attachment of the fastener. For this latter reason, KABLIT
also provides glue-on disks which, unfortunately, are permanently secured to the equipment.
The theft of small but expensive equipment such as desktop computers is a growing problem. Existing devices are simply too inefficient or ineffective, or their app:lication is too limited. As a result, the use of such security systems is rare, computer equipment is typically left unprotected, and it is all too often stolen.
