Definitions

  • the present invention relates to devices for inhibiting the theft of relatively small but expensive pieces of equipment.
  • desk top 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.
  • KBLIT Secure-It, Inc.
  • existing mounting screws i.e., screws which are already used to secure items of equipment within the cabinet.
  • 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, K ⁇ BLIT also provides glue-on disks which, unfortunately, are permanently secured to the equipment.
  • a computer physical security device of the prior art is known from WO 93/15295 upon which the preamble of the independent claims has been basted.
  • This known security device has an attachment mechanism for inhibiting theft of equipment.
  • the known security device includes a housing, cable attachment means coupled to said housing and a cable attached or attachable to said cable attachment means, for securing said housing to an object other than to the equipment to be secured.
  • the known device further comprises a shaft with a cross member extending from the housing. Also, abutment pins are emanating from the housing on opposite sides of the shaft.
  • the shaft with the cross member is insertable in a rectangular security slot after which the shaft and the abutment pins occupy the slot. Next, the cross member can be misaligned with the slot by rotation of the shaft thereby attaching the device to the external wall.
  • the present invention is set out in the independent claims 1 and 7. It inhibits the theft, of equipment such as personal computers.
  • the equipment must have an external wall provided with a specially designed, approximately rectangular slot having preselected dimensions.
  • the claimed systems are adaptable and convenient to use.
  • the only required modification of the equipment to be protected is a small (preferably about 3 by 7 millimeter) slot in an external wall. Additional brackets, capture mechanisms or the like are not necessary.
  • This small slot can easily be molded into computer systems at essentially no cost and without degrading the integrity of the equipment.
  • the attachment mechanism can readily be installed on the equipment, and removed when appropriate by an authorized user.
  • a lock assembly attaches a single item of equipment to an immovable object with the cable.
  • the cable passes through mating apertures in a housing forming a attachment mechanism to prevent their removal once they have been attached to the equipment and the cable has been installed.
  • the attachment mechanism is surprisingly difficult to remove from an item of equipment once it has been installed.
  • the mechanism is quite small, and it is difficult to apply sufficient leverage to break the mechanism away from the equipment to which it is attached. Forcibly removing the mechanism will result in significant, highly visible damage to the exterior wall, identifying the equipment as stolen and making it difficult to resell, greatly reducing its theft potential.
  • attachment mechanisms which are either integrally connected or separately coupled to engagement mechanisms for securing the attachment mechanism proximate the external wall of the object of equipment.
  • a security device 10 is illustrated generally by way of reference to Fig. 1 .
  • Security device 10 includes an attachment mechanism 12 designed to attach to a component of a computer system, such as computer monitor 14.
  • Attachment mechanism 12 has an aperture 16, and a cable 18 which passes through the aperture when the attachment mechanism 12 is attached to a component such as monitor 14.
  • a lock 20 is fixed to one end of cable 18.
  • the free end of cable 18 may be of the type having a "mushroom" head 22 adapted to penetrate and be secured within lock 20 using key 24.
  • a relatively immovable object (not shown) such as the cross bar spanning two legs of a desk. Mushroom head 22 is then inserted into lock 20 and the lock closed using key 24 to secure the computer components to the immovable object.
  • Embodiment 26 includes an attachment mechanism 28 designed to be secured to a computer component such as keyboard 30.
  • Attachment mechanism 28 is affixed to one end of a cable 32 which has a closed loop 34 at its other end. Cable 32 is first wrapped around a relatively immovable object, such as a cross piece between two legs of a desk or table, and attachment mechanism 28 is passed through loop 34 and attached to the item to be protected such as keyboard 30 to make it difficult to steal the item of equipment.
  • the devices 10 and 26 are designed to operate with items of equipment provided by a special slot, as illustrated in Fig. 2A.
  • the exterior wall 70 of the piece of equipment is typically made of sheet metal, or molded plastic, either of which is compatible with the present invention.
  • a relatively small slot 72 is formed in wall 70, by molding or otherwise as appropriate.
  • the slot has a generally rectangular configuration, i.e., the slot is generally rectangular having long parallel sides 74, short parallel sides 75 and rounded corners 76.
  • slot 72 is relatively small, having a long dimension 78 of seven millimeters, and a short dimension 79 of three millimeters.
  • Corners 76 have a radius of curvature 90 from 0.30 mm. to a maximum of 1.5 millimeters. If the radius of curvature 90 is 1.5 mm., the short sides 75 disappear and the slot has a straight-sided oval configuration.
  • the engagement mechanism includes at least two engagement portions for engaging with the inner surface of the external wall proximate the slot to prevent removal of the attachment mechanism from proximate the external wall.
  • Figs. 3A and 3B illustrate a device 800 in which there are also substantially only two component parts, an attachment mechanism 801 and an engagement mechanism 820.
  • Attachment mechanism 801 shown by way of reference to Fig. 3A , generally includes an attachment member 802 having a top end 804, a bottom end 806, and a cylindrical side wall 808.
  • a pair of apertures 810 are provided through side wall 808 and are sized to permit a cable 840 to pass through apertures 810 (See Fig. 3B
  • a generally cylindrical opening 812 is further provided in top end 804 of attachment member 802 and extends the length of the attachment member to a substantially smaller screw opening 814 in bottom end 806 of the attachment member. Opening 812 is configured to accommodate passage of screw 816 through opening 812 to bottom end 806 of the attachment member, as will be described in more detail hereinafter.
  • Engagement mechanism 820 is used in conjunction with attachment member 802, as is also illustrated in Fig. 3A .
  • Engagement mechanism 820 generally includes engagement member 822 having first and second, spaced apart engagement arms 824L and 824R connected to base portion 830 at the proximal end of engagement member 822 and defining a clearance space 825 between the arms sized large enough to permit screw. 816 to pass through clearance space 825.
  • Base portion 830 has a top surface 833 and a bottom surface 831 and is provided with a screw hole 832 through the surfaces.
  • Engagement portions 826L, 826R are integral with engagement arms 824L, 826R at the distal end of the arms.
  • engagement portions 826L, 826R have inwardly sloped side walls which facilitate insertion of the engagement portions into slot 852, as previously described.
  • engagement portions 826L, 826R are inserted into slot 852 until lower surface 831 of base portion 830 engages the outer surface of external wall 850.
  • attachment member 802 is positioned proximate upper surface 833 of base portion 830 until screw hole 832 is aligned with opening 814 in the attachment member.
  • Screw 816 is then inserted through each of opening 812 in the attachment member, opening 814 at the bottom end 806 of the housing, hole 832 in base portion 830, and clearance space 825.
  • the screw will force engagement arms 824L, 824R to spread apart so that engagement portions 826L, 826R will engage the inner surface of external wall 850 proximate slot 852.
  • cable 840 (See Fig. 6B) can be threaded through apertures 810 in the attachment member and attached to an external object, such as lock 860, to secure the attachment member to the lock.
  • the cable will also prevent removal of screw 816.
  • attachment mechanism concept of Figs. 3A and 3B can also be modified to include a conventional lock assembly 910 (as previously described by way of reference to the embodiment of Fig. 2 ) in combination with a retractable spindle arm 908.
  • attachment mechanism 900 is affixed to one end of a cable 920 which has a closed loop 922 at its other end. Cable 920 is first wrapped around a relatively immovable object (not shown) and attachment mechanism 900 is passed through loop 922 and attached to the item to be protected such as external wall 950 to make it difficult to steal.
  • Attachment mechanism 900 is shown in its retracted position in Fig. 4B , and generally includes a housing 902 and first and second, resilient engagement arms 904L and 904R which are mounted to the bottom end of housing 902 and extend outwardly therefrom.
  • Engagement arms 904L, 904R have first and second, inwardly angled engagement portions 906L and 906R at the distal end of each of the arms which are configured so as to be easily received within slot 952 in the retracted position of spindle arm 908, as will be described in more detail hereinafter.
  • a conventional cylindrical lock assembly 910 At the other end of housing 902 from the engagement arms.
  • a spindle arm 908 is adapted to be mounted to cylindrical lock assembly 910 at one end, with the opposite end of arm 90B extending between engagement arms 904L and 904R external of housing 902.
  • Spindle arm 908 is connected to lock assembly 910 in such a manner that rotation of lock assembly 910 with an appropriate key (not shown) will cause translational movement of spindle arm 908 in the direction of arrow 930 (see Fig. 4B ).
  • This movement of arm 908 can be accomplished in any manner as is well known in the art, as for example having spindle arm 908 received within a corkscrew shaped cam attachment mounted to lock assembly 910 so that rotation of the lock will cause corresponding translational movement of spindle arm 908.
  • engagement portions 906L and 906R are insertable into slot 952.
  • a key can be inserted into lock assembly 910 and rotated so that spindle arm 908 will be moved in the direction of arrow 930 to its extracted position.
  • the movement of spindle arm 930 along arrow 930 permits engagement arms 904L and 904R to flex outwards in the direction of arrow 940 so that engagement portions 906L and 906R will move outwards to engage the inner surface of slot 952.
  • attachment mechanism 900 will be secured proximate external wall 950.
