DETAILED DESCRIPTION

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.



FIG. 1 illustrates a system 10 including a portable electronic device 14 and a security apparatus 18. The illustrated portable electronic device 14 is a laptop or notebook computer. In other embodiments, the portable electronic device 14 may be another type of device, such as a smartphone, a tablet computer, an eReader, a desktop computer, a docking station, a Chip & PIN machine, a USB hub, and the like.


The security apparatus 18 attaches to the portable electronic device 14 to secure the device 14 to an immovable object 22. In the illustrated embodiment, the security apparatus 18 includes an anchor or adapter 26 (FIG. 2), a lock head 30, and a cable 34. As shown in FIG. 2, the anchor 26 is partially received in and attaches to a slot 38 (FIGS. 3-4) in the portable electronic device 14. The lock head 30 attaches to a portion of the anchor 26 to secure the lock head 30 to the portable electronic device 14. The cable 34 is attached to the lock head 30 and wraps around the immovable object 22 (as shown in FIG. 1) to secure the portable electronic device 14 in place. The immovable object 22 may be, for example, a desk, a chair, a wall, or other relatively secure structure. In some embodiments, the lock head 30 and the cable 34 may be similar to the ClickSafe® lock sold by Kensington and disclosed in U.S. Publication No. 2015/0368932, the entire contents of which are incorporated by reference herein.


Referring to FIGS. 3 and 4, the slot 38 is formed in the portable electronic device 14 and has an opening 42 and a cavity 46. The opening 42 is formed in an outer surface 50 of the portable electronic device 14. As shown in FIG. 3, the opening 42 is generally rectangular, but may alternatively have other shapes (e.g., a rounded rectangle, square, circle, etc.). The cavity 46 extends from the opening 42 into the portable electronic device 14. The illustrated cavity 46 is defined by two side walls 54 and a rear wall 58 of the portable electronic device 14. Top and bottom walls (not shown) can also partially define the cavity 46. As shown in FIG. 4, the side walls 54 taper outwardly from the opening 42 toward the rear wall 58, giving the slot 38 a generally trapezoidal shape when viewed in cross-section. The rear wall 58 defines an end of the cavity 46 opposite the opening 42, but in some embodiments, the rear wall 58 may be omitted.



FIGS. 5-8 illustrate an anchor 62 of a security apparatus. The anchor 62 attaches to a portable electronic device and may be used with the lock head 30 and the cable 34 shown in FIG. 1. The illustrated anchor 62 includes a body 66, two wedges or tapered projecting members 70, and a fastener 74. The body 66 has an insertable portion 78 and a boss 82 extending from the insertable portion 78. The insertable portion 78 is shaped and sized to be inserted through the opening 42 (FIG. 3) of the slot 38 and into the cavity 46. In the illustrated embodiment, the insertable portion has a rectangular cross section. The illustrated boss 82 is generally cylindrical and includes an enlarged end or cap 86, an annular recess 90 defining a central cylinder 94, and a ring structure 98. When the insertable portion 78 is inserted into the slot 38, the boss 82 remains outside of the slot 38 and accessible. The boss 82 (with the cap 86 and the annular recess 90) is configured to interact with the lock head 30 (FIG. 1). In the illustrated embodiment, the insertable portion 78 and the boss 82 are integrally formed as a single piece. In other embodiments, the insertable portion 78 and the boss 82 may be separate pieces that are secured together.


The wedges 70 are supported by the insertable portion 78. Each wedge 70 is positioned at least partially within the insertable portion 78. Each wedge 70 also includes an engagement surface 102 that is obliquely angled relative to a longitudinal axis of the anchor 62. The engagement surfaces 102 are shaped to match the contour of the side walls 54 (FIG. 4) in the portable electronic device 14. A wire pin 106 is coupled to the body 66 to retain and/or bias the wedges 70 within the insertable portion 78. In the illustrated embodiment, one end of the wire pin 106 is positioned within a recess 108 formed at least partly within the engagement surface 102 while the other end of the wire pin 106 is retained/fixed within the insertable portion 78. Alternatively, the wire pin 106 can be a clip or spring that biases the wedges 70 radially inward.


The fastener 74 extends through the body 66 and selectively engages the wedges 70. In the illustrated embodiment, the fastener 74 is a set screw, although other suitable fasteners or movable members may alternatively be used. The illustrated fastener 74 includes a head 110 adjacent the boss 82, a stem 112 extending from the head 110 into the insertable portion 78, and a threaded portion 114. In the illustrated embodiment, the threaded portion 114 is formed on the head 110. In other embodiments, the threaded portion 114 may be formed on the stem 112. The fastener 74 is rotatable by a tool (e.g., an Allen wrench, a screwdriver, etc.) that engages the head 110 to move the fastener 74 within the body 66. As the fastener 74 rotates, the fastener 74 moves linearly along the longitudinal axis of the anchor 62, toward or away from the wedges 70 (depending on the direction of rotation). The illustrated fastener 74 also includes a flange 115 that selectively engages a shoulder pin 117, or other suitable projection, extending through the body 66 to limit movement of the fastener 74 out of the body 66.


Referring to FIGS. 7A and 7B, the anchor 62 is movable between a first or disengaged position (FIG. 7A) in which the wedges 70 are retracted into the insertable portion 78, and a second or engaged position (FIG. 7B) in which fastener 74 pushes the wedges 70 outward from the insertable portion 78. When the fastener 74 moves in the direction of arrow A, the distal end of the fastener 74 engages radially inwardly-facing surfaces 116 of the wedges 70 to push the wedges 70 radially outward (i.e., in the direction of arrows X). In the illustrated embodiment, the inwardly-facing surfaces 116 each include a tapered lead-in portion 116a to facilitate smooth extension of the wedges 70 upon initial engagement with the fastener 74. In the illustrated embodiment, the wedges 70 translate linearly away from one another in opposite directions. In other embodiments, the wedges 70 could pivot or rotate, or could undergo motion that is a combination of both translation and rotation.


In this extended position, the wedges 70 can engage the side walls 54 (FIG. 4) of the portable electronic device 14 to secure the anchor 62 within the slot 38. Because the wedges 70 extend and are secured in the extended position beyond the perimeter of the opening 42, the anchor 62 cannot be removed from the slot 38. When the fastener 74 moves in the direction of arrow B, the fastener 74 disengages the radially inwardly-facing surfaces 116 of the wedges 70, allowing the wedges 70 to be free of any load that would resist movement of the wedges 70 in the direction of arrows Y. Pulling on the boss 82 away from the slot 38 (i.e., in the direction of arrow B), allows the wedges 70 to move or retract radially inward (see FIG. 7A). In this position, the wedges 70 are positioned within or retracted into the insertable portion 78 so that the insertable portion 78 can be removed from or inserted into the slot 38 in the portable electronic device 14.



FIGS. 9-10 illustrate another anchor 118 of a security apparatus. The anchor 118 attaches to a portable electronic device and may be used with the lock head 30 and the cable 34 shown in FIG. 1.

The second engagement surface 214 is configured to engage the other side wall 54 (FIG. 4) of the portable electronic device 14.


The fastener 198 is movable to selectively engage the wedge 194. As the fastener 198 moves toward the wedge 194 (i.e., in the direction of arrow A), the fastener 198 pushes the wedge 194 to pivot the wedge 194 about the pin 210. In this position, the second engagement surface 214 of the wedge 194 spreads apart or extends from the first engagement surface 206 of the insertable portion 202 to secure the anchor 186 within the slot 38. As the fastener 198 moves away from the wedge 194 (i.e., in the direction of arrow B), the fastener 198 disengages the wedge 194 such that the wedge 194 is free to pivot back or retract toward insertable portion 202. In this position, the second engagement surface 214 of the wedge 194 moves toward the first engagement surface 206 of the insertable portion 202, allowing the insertable portion 202 and the wedge 194 to be inserted into or removed from the slot 38.



FIGS. 19-20 illustrate another anchor 218 of a security apparatus. The anchor 218 attaches to a portable electronic device and may be used with the lock head 30 and the cable 34 shown in FIG. 1.
