DETAILED DESCRIPTION

(22) Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways.

(23) FIGS. 1-6 illustrate a clamp lock 10 for use with a portable electronic device 14 (FIG. 7). The clamp lock 10 is configured to engage a relatively thin portion, or sheet, of the portable electronic device 14, such as the kickstand of a Microsoft® Surface Pro computer. In other embodiments, the clamp lock 10 may engage suitable components (e.g., relatively thin portions) of other types of devices. The clamp lock 10 secures the portable electronic device 14 to an immovable object (e.g., a desk, a table, a chair, a bracket, a wall, etc.) to inhibit theft of the portable electronic device 14.

(24) The illustrated clamp lock 10 includes a body 18, a lock mechanism 22 (FIG. 5), a clamping member 26 (FIGS. 3 and 5), and a security member 30. In the illustrated embodiment, the body 18 includes a first or main body portion 34, a second or front body portion 38, and a cover plate 42. The front body portion 38 is coupled to the main body portion 34 by fasteners 46 (e.g., screws). The cover plate 42 extends over a front face 50 of the front body portion 38 to substantially cover the fasteners 46. The cover plate 42 is welded, glued, or otherwise secured to the front body portion 38 to inhibit access to the fasteners 46 and, thereby, disassembly of the body 18. In some embodiments, the cover plate 42 may include a logo or other indicia associated with the clamp lock 10. In some embodiments, the fasteners may be modified to prevent disassembly.

(25) When assembled, the illustrated body 18 is generally C-shaped. The body 18 has a slot 54 formed between a lower leg 58 of the main body portion 34 and a lower surface 62 of the front body portion 38. The slot 54 is configured to receive part of a portable electronic device. In the illustrated embodiment, the slot 54 has an opening 66 at an outer periphery of the body 18 (i.e., near the cover plate 42) and an inner channel 70 located inward of the opening 66. The inner channel 70 is in communication with the opening 66. As shown in FIG. 4, the opening 66 has a first height H1 measured between the lower leg 58 of the main body portion 34 and the lower surface 62 of the front body portion 38. The inner channel 70 has a second height H2 measured between the lower leg 58 of the main body portion 34 and the lower surface 62 of the front body portion 38. The second height H2 is larger than the first height H1 such that a lip 74 is formed in the lower leg 58 at the transition between the opening 66 and the channel 70. The lip 74 helps the clamp lock 10 engage a ledge on a portable electronic device without being pulled off of the portable electronic device, as further explained below.

(26) As shown in FIGS. 5 and 6, the lock mechanism 22 is supported by the body 18. More particularly, the lock mechanism 22 is positioned within the body 18. The illustrated lock mechanism 22 includes a lock cylinder 78 and an actuation cam 82. The lock cylinder 78 is configured to be engaged and rotated by a key. The actuation cam 82 is coupled to the lock cylinder 78 for rotation with the lock cylinder 78. As the actuation cam 82 rotates, the actuation cam 82 engages the clamping member 26 to move the clamping member 26. In other embodiments, the lock mechanism 22 may include, for example, a combination lock and manual actuator to selectively move the actuation cam 82.

(27) The clamping member 26, or locking pad, is supported by the body 18 and operatively coupled to the lock mechanism 22. In the illustrated embodiment, the clamping member 26 is positioned at least partially within the front body portion 38 of the body 18 generally beneath the actuation cam 82 of the lock mechanism 22. The clamping member 26 includes a generally planar lower surface 86 facing the slot 54 and the lower leg 58 of the body 18. The planar surface 86 is described herein as the “lower” surface to facilitate description with reference to the drawings, but it should be understood that the planar surface 86 may be an “upper” or “side” surface depending on the orientation of the clamp lock 10. More accurately, the planar lower surface 86 is the surface of the clamping member 26 that faces the lower leg 58. The planar lower surface 86 is configured to selectively engage part of a portable electronic device that is received within the slot 54 to inhibit removal of the portable electronic device from the slot 54. The clamping member 26 also includes a cam surface 90 facing and aligned with the actuation cam 82 of the lock mechanism 22. As the actuation cam 82 is rotated, the actuation cam 82 pushes against the cam surface 90 to move the clamping member 26. The planar lower surface 86 can have a surface coating or anti-scratch film to prevent the creation of scratches and abrasions to the portable electronic device when assembling and disassembling.

(28) The clamping member 26 is movable between a first or engaged position (FIG. 3) and a second or disengaged position (FIG. 4). As shown in FIG. 3, when in the engaged position, at least part of the clamping member 26 extends into the slot 54 of the body 18. In this position, the clamping member 26 is moved toward the lower leg 58 of the body 18 (downward in FIG. 3) and is configured to engage the part of the portable electronic device that is received within the slot 54. As shown in FIG. 4, when in the disengaged position, the clamping member 26 is moved away from the lower leg 58 of the body 18 (upward in FIG. 4). In this position, the clamping member 26 disengages the part of the portable electronic device received within the slot 54 so that the clamp lock 10 can be removed from the portable electronic device. In the illustrated embodiment, the clamping member 26 is completely received within the body 18 when moved to the disengaged position. In other embodiments, the clamping member 26 may still extend partially into the slot 54 when in the disengaged position, but to a lesser degree than when in the engaged position.

(29) In the illustrated embodiment, the clamping member 26 is biased to the disengaged position (upward in FIG. 4) by a spring 94 (e.g., a coil compression spring). The clamping member 26 is moved against the bias of the spring 94 to the engaged position (downward in FIG. 3) by the actuation cam 82. In some embodiments, suitable structures or mechanisms (e.g., a rail and groove) may be used restrict movement of the clamping member 26 to linear motion.

(30) As shown in FIGS. 5 and 6, the security member 30 is coupled to the body 18. The security member 30 is configured to be coupled to an immovable object to inhibit movement of the clamp lock 10 (and, thereby, an attached portable electronic device) away from the immovable object. In the illustrated embodiment, the security member 30 includes a flexible cable 106 that is connected to the body 18 by a ferrule 110. The flexible cable 106 is configured to be wrapped around the immovable object (e.g., wrapped around the leg of a chair or table). The ferrule 110 is secured to the body by an attachment pin 114 extending through part of the body 18. The illustrated ferrule 110 includes a pivot joint 118 to allow some movement of the body 18 relative to the cable 106 without twisting the cable 106. In other embodiments, other suitable security members (e.g., threaded fasteners, adhesives, brackets, etc.) may be used to secure the body 18 of the clamp lock 10 to an immovable object.

(31) FIG. 7 illustrates the portable electronic device 14 for use with the clamp lock 10. In the illustrated embodiment, the portable electronic device 14 is a Microsoft® Surface Pro computer having a main body 122 with a screen and a processor, a keyboard 126, and a kickstand 130. In other embodiments, the clamp lock 10 may be used with other suitable portable electronic devices having a relatively thin sheet or section that is similar to the kickstand 130 of the illustrated device 14.

(32) As shown in FIGS. 8 and 9, the illustrated kickstand 130 is a relatively thin and rigid sheet having an outer edge 134. The kickstand 130 also includes a ledge 138 formed around the outer edge 134. The ledge 138 is generally thicker than the remainder of the kickstand 130. When the outer edge 134 of the kickstand 130 is received in the slot 54 of the clamp lock 10, as shown in FIG. 9, the ledge 138 abuts the lip 74 of the clamp lock 10, inhibiting the clamp lock 10 from being pulled off of the kickstand 130. As such, the clamp lock 10 engages the kickstand 130 (or other thin sheet of a portable electronic device) in a relatively secure manner.

(33) FIGS. 10A-14B illustrate further locking adaptors for providing physical security to a portable electronic device having a kickstand and/or no integrated security slot. The locking adaptors interface with separate “laptop locks” to form different types of clamp locks. Specifically, FIG. 10A-10D illustrate a locking adaptor 100 according to one embodiment of the invention. The illustrated locking adaptor 100 includes two legs 104, 108 that are pivotally coupled together, but biased apart. The legs 104, 108 are positioned on opposing sides of a thin sheet 112, and a shroud 116 is slid over the legs 104, 108 to press the legs 104, 108 together. The shroud 116 includes a slot for attachment to a laptop lock 120 (e.g., a Kensington T-bar lock, etc.) having a cable 124 that can be secured to an immovable object. When attached, the laptop lock 120 inhibits the shroud 116 from sliding off of the legs 104, 108 and, thereby, inhibits the legs 104, 108 from disengaging the thin sheet 112.

(34) FIG. 10E illustrates an alternative locking adaptor 100′ that is similar to the locking adaptor 100. The illustrated locking adaptor 100′ includes a slot 128 implemented in one of the legs 108. When the shroud 116 is positioned over the legs 104, 108 and the laptop lock 120 is attached to the slot 128, the laptop lock 120 inhibits the shroud 116 from sliding off of the legs 104, 108 by physically blocking movement of the shroud 116 (i.e., the body of the laptop lock 120 is larger than the clearance required to move the shroud 116).

(35) FIG. 11 illustrates a locking adaptor 200 according to another embodiment of the invention. The illustrated locking adaptor 200 includes three separate parts 204, 208, 212. Two mating parts 204, 208 are positioned on opposing sides of a thin sheet 216, and the third part 212 is slid over the two mating parts 204, 208. One of the two mating parts 204 and the third part 212 both include slots 220, 224 for attachment to a laptop lock 228 having a cable 232 that can be secured to an immovable object. When attached, the laptop lock inhibits 228 the locking adaptor 220 from being disassembled and removed from the thin sheet 216.

(36) FIGS. 12A-12B illustrate a locking adaptor 300 according to yet another embodiment of the invention. The illustrated locking adaptor 300 includes a first component 304 that is slid onto an edge of a thin sheet 308, and a second component 312 that slides on a track of the first component 304. The two components 304, 312 may be assembled relative to one another prior to or after locating the components 304, 312 relative to the thin sheet 308. The first component 304 and the second component 312 both include slots 316, 320 for attachment to a laptop lock having a cable that can be secured to an immovable object. When the slots 316, 320 are aligned and adjacent, the laptop lock is attached to the slots 316, 320 to inhibit the second component 312 from sliding relative to the first component 304 and disengaging the thin sheet 308.

(37) FIGS. 13A-13B illustrate a locking adaptor 400 according to still another embodiment of the invention. The illustrated locking adaptor 400 includes two halves 404, 408 rotatably coupled together. The first half 404 is positioned on one side of a thin sheet 412, and the second half 408 is positioned on another side of the thin sheet 412. The second half 408 is then rotated to a closed position (FIG. 13B), in which the first and second halves 404, 408 are generally aligned to capture part of the thin sheet 412 between the two halves 404, 408. The second half 408 includes a slot 416 for attachment to a laptop lock having a cable that can be secured to an immovable object. When attached, the laptop lock inhibits the second half 408 from rotating open relative to the first half 404 and, thereby, disengaging the thin sheet 412.

(38) FIGS. 14A-14B illustrate a locking adaptor 500 according to yet still another embodiment of the invention. The illustrated locking adaptor 500 includes two bars 504, 508 that are positioned on opposing sides of a thin sheet 512. The bars 504, 508 extend an entire dimension (e.g., length or width) of the thin sheet 512. Both bars 504, 508 include slots 516, 520 for attachment to a laptop lock 524 having a cable 528 that can be secured to an immovable object. When the slots 516, 520 are aligned, the laptop lock 524 is attached to the slots 516, 520 to inhibit the bars 504, 508 from separating and disengaging the thin sheet 512.

(39) The locking adaptors provide physical security to Microsoft® Surface Pro products or similar devices with a kickstand or no integrated security slot. A main advantage of the locking adaptors is to easily secure onto the device's kickstand with a sliding, rotating, or clamping component. With one of the locking adaptors affixed around the device's kickstand, a laptop lock is used to secure the locking adaptor, anchoring the locking adaptor onto the device. This arrangement offers users a non-intrusive security solution for thin and mobile devices that include a thin sheet or component, such as a kickstand.

(40) The locking adaptors can be composed of, for example, CNC machined, die cast, or stamped metal parts in order to provide desired strength requirements. Each locking adaptor can also incorporate injection molded components or anti-scratch adhesive-backed films where strength is not as necessary, or for scratch resistance on a contacting surface. To anchor the locking adaptors onto a device's kickstand, a user can rotate, slide, or clamp the parts together. This configuration allows the locking adaptors to stay attached to the device without a lock. With a laptop lock inserted, the locking adaptors and attached device are secured from potential theft.

(41) The locking adaptors provide non-intrusive security solutions for devices with a kickstand (or other thin sheet) and no integrated security slot. Each adaptor can be quickly installed or removed from the device, for an effortless user experience. The adaptors are small and compact, making them useful for on-the-go security while in a more portable user environment. A laptop lock, such as a Kensington® lock, is used with each adaptor as the last step to restrict removal of the adaptor from the kickstand.

(42) Various features and advantages of the invention are set forth in the following claims.
