Computer physical security device
View Patent ↗An apparatus which inhibits the theft of equipment such as personal computers is disclosed. The equipment must have an external wall provided with a specially designed, approximately rectangular slot having preselected dimensions. An attachment mechanism includes a housing for a spindle having a first portion rotatable within the housing, a shaft extending outwardly from the housing, and a crossmember at the end of the shaft having peripheral dimensions closely conforming to the internal dimensions of the slot. An abutment mechanism also emanates from the housing, and is located on opposite sides of the shaft intermediate the housing and the crossmember. The peripheral cross-sectional dimensions of the abutment mechanism and the shaft in combination closely conform to the dimensions of the slot. The length of the shaft from the housing to the crossmember is approximately equal to the thickness of the external wall of equipment. The crossmember is aligned with the abutment mechanism so that the crossmember can be inserted through the slot with the shaft and the abutment mechanism occupying the slot. The spindle is then rotated 90° to misalign the crossmember with the slot, thereby attaching the attachment mechanism rigidly to the external wall. A cable is secured to the housing and to an immovable object so that the equipment cannot be stolen.
1. A method comprising:
obtaining a portable electronic device having an external wall with a thickness, wherein the wall has a security slot that has dimensions of about 3 millimeters by about 7 millimeters;
obtaining a locking apparatus comprising an attachment mechanism comprising a slot engagement member, wherein the slot engagement member is capable of insertion into the security slot in the wall of the portable electronic device and is capable of being secured to the portable electronic device via the security slot;
inserting the slot engagement member into the security slot; and
moving the slot engagement member, wherein moving the slot engagement member comprises using a key to move the slot engagement member to a locked position.
2. The method of claim 1 wherein the security slot is generally rectangular in shape.
3. The method of claim 1 wherein the slot engagement member comprises a shaft and a crossmember at an end of the shaft.
4. The method of claim 1 wherein the slot engagement member is capable of rotating between the locked position and an unlocked position.
5. The method of claim 1 wherein the attachment mechanism further comprises a cylindrical housing and a pin, wherein the slot engagement member and the pin are at least partially enclosed in the cylindrical housing.
6. The method of claim 1 wherein the attachment mechanism further comprises a housing and a pin, wherein the slot engagement member and the pin are at least partially enclosed in the housing.
7. The method of claim 1 wherein the slot engagement member has dimensions smaller than about 3 millimeters by about 7 millimeters.
8. The method of claim 1 wherein the slot engagement member has a shaft that is longer than the thickness of the wall.
9. The method of claim 1 wherein the attachment mechanism comprises a pin adjacent to the slot engagement member.
10. The method of claim 1 wherein a cable is attached to the attachment mechanism and wherein the method further comprises wrapping the cable around an immovable object to secure the portable electronic device to the immovable object.
11. The method of claim 10 wherein the cable comprises a loop, and wherein the method includes inserting the attachment mechanism through the loop.
12. The method of claim 1 wherein the portable electronic device comprises a computer.
13. The method of claim 1 wherein the attachment mechanism comprises a lock, and wherein the key is configured to lock and unlock the lock.
14. The method of claim 13 , wherein a cable is attached to the attachment mechanism, and the cable comprises a loop, and wherein the method includes inserting the attachment mechanism through the loop.
15. The method of claim 13 wherein the portable electronic device comprises a computer.
16. The method of claim 13 wherein a cable is attached to the attachment mechanism and wherein the method further comprises wrapping the cable around an immovable object to secure the portable electronic device to the immovable object.
