Abstract

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.

Claims

1. A locking method for a portable electronic device, comprising the steps of:

engaging a generally rectangular security slot, having dimensions of about 3 mm×

7 mm, defined in a wall of the portable electronic device with a moveable locking member;

moving said locking member to a locked position relative to said security slot to configure said locking member in a locked configuration; and

maintaining said locked configuration by use of a pin proximate said locking member;

wherein said pin extends into said security slot.

2. The locking method of claim 1 wherein said locking member rotates to said locked position.

3. The locking method of claim 1 wherein said pin extends into said security slot after said locking member has moved to said locked position.

4. The locking method of claim 1 wherein said locking member is coupled to a housing and further comprising the step of localizing said housing to an object other than to the portable electronic device.

5. The locking method of claim 4 wherein said localizing step includes the step of associating a cable, coupled to said housing, to said object.

6. The locking method of claim 2 wherein said pin enters into said security slot before said locking member moves to said locked position.

7. The locking method of claim 1 wherein a lock secures said locking member into said locking position.

8. The locking method of claim 1 wherein a lock secures said pin.

9. The locking method of claim 7 wherein said lock is a keyed tumbler lock.

10. The locking method of claim 7 wherein said lock is an interlocking system of aligned apertures with a second object passing therethrough to maintain a locked configuration.

11. The locking method of claim 10 wherein said second object is a cable.

12. The locking method of claim 8 wherein said lock is a keyed tumbler lock.

13. The locking method of claim 8 wherein said lock is an interlocking system of aligned apertures with a second object passing therethrough to maintain a locked configuration.

14. The locking method of claim 13 wherein said second object is a cable.
