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. In the illustrated embodiment, the portable electronic device 14 is a laptop computer, but may alternatively be a tablet computer, a smartphone, an eReader, an MP3 player, and the like. The illustrated portable electronic device 14 includes a housing 22, a processor 26 positioned within the housing 22, and a screen 30 supported by the housing 22. In some embodiments, the screen 30 may be a touchscreen. In other embodiments, such as the illustrated embodiment, the portable electronic device 14 may also or alternatively include other input mechanisms, such as a keyboard, keypad, or touchpad. The security apparatus 18 is connected to the portable electronic device 14 and includes a cable 34 to secure the portable electronic device 14 to an immovable object 38, such as a table, a chair, a bracket, a wall, and the like.

As shown in FIGS. 2-5, the portable electronic device 14 has an aperture 42, or slot, formed in the housing 22. The illustrated aperture 42 is generally smaller than existing security slots in portable electronic devices, and is specifically designed for thinner devices with smaller housings. The aperture 42 is defined by an upper wall 43, a lower wall 44, two opposing sidewalls 45, and a rear wall 46. As shown in FIG. 5, the upper and lower walls 43, 44 are generally parallel to each other. The upper wall 43 has a first section 43A near the outer surface of the housing 22, and a second section 43B inward of the first section 43A. Similarly, the lower wall 44 has a first section 44A near the outer surface of the housing 22, and a second section 44B inward of the first section 44A. The second sections 43B, 44B are slightly offset relative to the first sections 43A, 44A. As shown in FIG. 4, the sidewalls 45 are generally parallel to each other and perpendicular to the upper and lower walls 43, 44. Each sidewall 45 has a first section 45A near the outer surface of the housing 22, and a second section 45B inward of the first section 45A. The second sections 45B are outwardly offset from the first sections 45A such that a shoulder or ledge 45C is formed between the first and second sections 45A, 45B. The rear wall 46 extends between and connects the upper wall 43, the lower wall 44, and the sidewalls 45. The rear wall 46 also closes the back of the aperture 42 to separate the aperture 42 from the internal components of the device 14.

By way of example, the aperture 42 can have an external width W₁ (measured between the first sections 44A of the sidewalls 44) of about 6 mm. The aperture 42 can also have an external height H₁ (measured between the upper and lower walls 43A, 43B) of about 2.5 mm. In addition, the aperture 42 can have an internal width W₂ (measured between the second sections 44B of the sidewalls 44) of at least 9 mm. Further, the aperture 42 can have an internal depth D (measured from the outer surface of the housing 22 to the rear wall 46) of at least 7 mm. The internal depth D is defined by a wall thickness T (i.e., the length of the first sections 43A, 44A, 45A) and a clearance depth C (i.e., the length of the second sections 43B, 44B, 45B). In some embodiments, the wall thickness T may be 3.5 mm±0.25 mm. Additionally, the clearance depth C may be at least 3.5 mm. The aperture 42 can also have an internal height H₂ (measured between the second sections 43B, 44B of the upper and lower walls 43, 44) of at least 2.65 mm. In other embodiments, the aperture 42 can have other dimensions. The aperture 42 is configured to receive an engagement mechanism of a security apparatus, such as one of the security apparatuses described below.

FIGS. 6-11 illustrate one example of the security apparatus 18. The security apparatus 18 includes a cylindrical body 48, a lock mechanism 50, and an engagement mechanism 54. The cylindrical body 48 is made of a relatively hard material, such as metal, and houses other components of the security apparatus 18. In other embodiments, the cylindrical body 48 can have other, non-cylindrical shapes. The illustrated body 48 includes a knurled section 58 to facilitate grasping and holding the security apparatus 18.

As shown in FIGS. 9-11, the illustrated lock mechanism 50 includes a lock cylinder 62 and a cam member 66. The lock cylinder 62 and the cam member 66 are positioned within the cylindrical body 48. The lock cylinder 62 is arranged in line with the engagement mechanism 54 along a longitudinal axis 70 of the security apparatus 18. As such, the lock cylinder 62 also defines the longitudinal axis 70 and is actuatable (e.g., rotatable) about the axis 70. In the illustrated embodiment, the lock cylinder 62 is rotatable by, for example, a key 74 (FIG. 6). In other embodiments, the lock mechanism 50 may include a combination-style lock.

The cam member 66 is coupled to the lock cylinder 62 for rotation with the lock cylinder 62 about the longitudinal axis 70. In particular, the cam member 66 includes a stem 78 that extends into the lock cylinder 62, and a cam body 82 positioned forward of the lock cylinder 62 and engaging the engagement mechanism 54. In the illustrated embodiment, the cam member 66 has slots 86 formed in the cam body 82. The illustrated slots 86 are arcuate slots that curve around the circumference of the cam body 82. The slots 86 are also obliquely angled relative to the longitudinal axis 70 so that the slots 86 helically wind around cam body 82. Each slot 86 includes a first end 90 adjacent the engagement mechanism 54, a second end 94 adjacent the lock cylinder 62, and a detent 98 formed at the first end 90. In other embodiments, the cam member 66 may include fewer or more slots 86 formed in the cam body 82.

As shown in FIGS. 7-8 and 11, the illustrated engagement mechanism 54 includes two fingers 102 and a plunger 106. The fingers 102 are movable (e.g., pivotable) between an unlocked or retracted position (FIG. 7) and a locked or expanded position (FIG. 8). When the fingers 102 are in the unlocked position, the engagement mechanism 54 is insertable into and removable from the aperture 42 in the portable electronic device 14 (FIGS. 1-5). When the fingers 102 are in the locked position, the engagement mechanism 54 engages the housing 22 of the portable electronic device 14 to secure the security apparatus 18 to the device 14. Each finger 102 includes an enlarged distal end 110 and a relatively narrower stem 114. The enlarged distal ends 110 facilitate engaging (e.g., contacting or “grabbing) the housing 22 of the portable electronic device 14 so that the security apparatus 18 cannot be pulled out of the aperture 42. Particularly, the enlarged distal ends 110 engage the ledges 45C of the sidewalls 45 (FIG. 4) formed by the aperture 42. The relatively narrower stems 114 create a recessed area 118 between the fingers 102 for receiving the plunger 106. Each finger 102 also includes a boss 116 at an end of the stem 114 opposite from the enlarged distal end 110. The bosses 116 define spaced apart pivot axes for the fingers 102.

The plunger 106 is positioned between the fingers 102 to selectively move the fingers 102 from the unlocked position to the locked position. The plunger 106 includes cam followers 122 that are received in the slots 86 of the cam member 66. In the illustrated embodiment, the cam followers 122 are pins. In other embodiments, the plunger 106 may include fewer or more cam followers 122, depending on the number of slots 86 in the cam member 66. The plunger 106 is movable (e.g., slidable) along the longitudinal axis 70 to selectively actuate the fingers 102. The security apparatus 18 also includes an end cap 126 coupled to the cylindrical body 48 opposite from the lock cylinder 62 to help retain the fingers 102 and the plunger 106 in connection with the lock mechanism 50 and the body 48.

Referring to FIG. 7, in an initial position (i.e., when the fingers 102 are in the unlocked position), the cam followers 122 of the plunger 106 are positioned at the second ends 94 of the slots 86 in the cam member 66. In this position, a distal end section of the plunger 106 is received within the recessed area 118 formed between the fingers 102. The fingers 102 are moved (e.g., pivoted) toward each other so that the enlarged distal ends 110 contact each other. In some embodiments, the engagement mechanism 54 may include a spring element, such as an elastomeric ring 130 shown in FIG. 11, to help move the fingers 102 toward each other. In this position, the engagement mechanism 54 can be inserted into or removed from the aperture 42 of the portable electronic device 14.

Referring to FIGS. 8-10, when the cam member 66 is rotated (e.g., by rotating the lock cylinder 62 with the key 74), the cam followers 122 follow the slots 86 of the cam member 66 to move the plunger 106 axially outward. As the plunger 106 slides axially outward (i.e., in the direction of arrow A), the plunger 106 pushes the fingers 102 apart from each other (i.e., in the direction of arrows B). More particularly, the fingers 102 are pushed and expanded radially outward to engage the housing 22 of the portable electronic device 14 (if the engagement mechanism 54 is inserted into the aperture 42 of the portable electronic device 14). The cam member 66 is rotated about 90 degrees until the cam followers 122 reach the first ends 90 of the slots 86. As shown in FIG. 10, each cam follower 122 is received in the corresponding detent 98 at the first end 90 of the slot 86 when in the locked position. In this position, the engagement mechanism 54 is inhibited from being removed from (e.g., pulled out of) the aperture 42 of the device 14. In addition, the detents 98 provide recesses that inhibit the cam followers 122 from being bumped out of the first ends 90 of the slots 86 and moved back toward the second ends 94 of the slots 86 without purposefully rotating the cam member 66 (e.g., with the key 74).

As shown in FIGS. 6 and 11, the security apparatus 18 also includes a cable mount 134 supported by the cylindrical body 48. The illustrated cable mount 134 is positioned generally between the lock mechanism 50 and the engagement mechanism 54. The cable mount 134 includes a boss 138 extending radially from the cylindrical body 48. The cable mount 134 is configured to securely receive an end of the flexible cable 34, which can be wrapped around an immovable object 38 (FIG. 1) to secure the security apparatus 18 (and, thereby, the portable electronic device 14) to the immovable object 38.

FIGS. 12-17 illustrate another example of a security apparatus 218. The security apparatus 218 is similar to the security apparatus 18 discussed above with reference to FIGS. 6-11. Differences between the two security apparatuses 18, 218 are described below.

The security apparatus 218 includes a body 222, a lock mechanism 226, and an engagement mechanism 230. The body 222 has a first body portion 234 that generally houses the lock mechanism 226, and a second body portion 238 that generally houses the engagement mechanism 230. In the illustrated embodiment, the body portions 234, 238 are arranged generally perpendicular to each other so that the first body portion 234 extends upward (e.g., away from a table or other surface supporting the portable electronic device 14) relative to the second body portion 238.

As shown in FIGS. 15-17, the illustrated lock mechanism 226 includes a lock cylinder 242 and a cam member 246. The lock cylinder 242 is arranged at 90 degrees relative to a longitudinal axis 250 of the engagement mechanism 230 and the second body portion 238. The lock cylinder 242 is rotatable by, for example, a key 254 (FIG. 12). In other embodiments, the lock mechanism 226 may include a combination-style lock.

The cam member 246 is coupled to the lock cylinder 242 for rotation with the lock cylinder 242. In particular, the cam member 246 includes a stem 258 that extends into the lock cylinder 242, and an enlarged cam 262 coupled to a distal end of the stem 258, opposite from the lock cylinder 242. The enlarged cam 262 engages the engagement mechanism 230 to actuate the engagement mechanism 230.

With continued reference to FIGS. 13-17, the illustrated engagement mechanism 230 includes two fingers 266 and plunger 270. The fingers 266 are movable (e.g., pivotable) between an unlocked or retracted position (FIG. 13) and a locked or expanded position (FIG. 14). When the fingers 266 are in the unlocked position, the engagement mechanism 230 is insertable into and removable from the aperture 42 in the portable electronic device 14 (FIGS. 1-5). When the fingers 266 are in the locked position, the engagement mechanism 230 engages the housing 22 of the portable electronic device 14 to secure the security apparatus 218 to the device 14.

The illustrated plunger 270 is partially received in a guide block 272. The guide block 272 helps restrict movement of the plunger 270 to linear sliding movement in the direction of arrow C. The guide block 272 also forms part of a bottom section of the body 222. In the illustrated embodiment, the guide block 272 is a separate piece from the rest of the body 222 to facilitate assembling the security apparatus 218.

In the illustrated embodiment, the fingers 266 are moved between the unlocked and locked positions by rotating the cam member 246 with the lock cylinder 242. More particularly, the plunger 270 includes a recess 274, or cam follower, that receives the enlarged cam 262 of the cam member 246. When the cam member 246 is rotated (e.g., by rotating the lock cylinder 242 with the key 254), the enlarged cam 262 pushes the plunger 270 axially outward or inward, depending on which direction the cam member 246 is rotated. As the plunger 270 slides axially outward (i.e., in the direction of arrow C), the fingers 266 are pushed apart and expanded radially outward (i.e., in the direction of arrows D). As the plunger 270 slides axially inward, the fingers 266 can move toward each other. In the illustrated embodiment, the distal ends of the fingers 266 include corresponding cutouts 278 such that the fingers 266 can slightly overlap when in the unlocked position (as shown in FIG. 13). In some embodiments, the engagement mechanism 230 may include a spring element, such as an elastomeric ring 280 shown in FIG. 17, to help move the fingers 266 toward each other.

As shown in FIGS. 12 and 17, the security apparatus 218 also includes a cable mount 282 supported at an end of the body 222 opposite from the engagement mechanism 230. The cable mount 282 is configured to securely receive an end of a flexible cable 286. The flexible cable 286 can be, for example, wrapped around an immovable object 38 (FIG. 1) to secure the security apparatus 218 to the immovable object 38. The illustrated cable mount 282 also includes a joint 290 that allows the cable 286 to be pivoted relative to the body 222.

FIGS. 18-23 illustrate another example of a security apparatus 318. The security apparatus 318 is similar to the security apparatus 18 discussed above with reference to FIGS. 6-11. Differences between the two security apparatuses 18, 318 are described below.

The security apparatus 318 includes a body 322, a lock mechanism 326, and an engagement mechanism 330. The body 322 has a first body portion 334 that generally houses the lock mechanism 326, and a second body portion 338 that generally houses the engagement mechanism 330. The body portions 334, 338 are obliquely angled relative to each other. For example, in the illustrated embodiment, the first body portion 334 is angled about 45 degrees relative to the second body portion 338 such that the first body portion 334 extends upwardly and rearwardly from the second body portion 338.

As shown in FIGS. 21-22, the illustrated lock mechanism 326 includes a lock cylinder 342 and a cam member 346. The lock cylinder 342 is arranged at 45 degrees relative to a longitudinal axis 350 of the engagement mechanism 330 and the second body portion 338. The lock cylinder 342 is rotatable by, for example, a key 354 (FIG. 18). In other embodiments, the lock mechanism 326 may include a combination-style lock.

The cam member 346 is coupled to the lock cylinder 342 for rotation with the lock cylinder 342. In particular, the cam member 346 includes a stem 358 that extends into the lock cylinder 342, and an enlarged cam 362 coupled to a distal end of the stem 358, opposite from the lock cylinder 342. The illustrated enlarged cam 362 includes a cam surface 366 facing and contacting the engagement mechanism 330.

The illustrated engagement mechanism 330 includes two fingers 370 and a cam follower 374. The fingers 370 are movable (e.g., pivotable) between an unlocked or retracted position (FIG. 19) and a locked or expanded position (FIG. 20). When the fingers 370 are in the unlocked position, the engagement mechanism 330 is insertable into and removable from the aperture 42 in the portable electronic device 14 (FIGS. 1-5). When the fingers 370 are in the locked position, the engagement mechanism 330 engages the housing 22 of the portable electronic device 14 to secure the security apparatus 318 to the device 14.

The cam follower 374 is positioned between the fingers 370 and the cam member 346. The illustrated cam follower 374 includes two wings 378, each of which engages one of the fingers 370. The wings 378 have ramped surfaces 382 that selectively press proximal ends 386 of the fingers 370 together, causing distal ends 390 of the fingers 370 to spread apart.

In the illustrated embodiment, the fingers 370 are moved between the unlocked and locked positions by rotating the cam member 346 with the lock cylinder 342. More particularly, the cam follower 374 abuts the cam surface 366 of the cam member 346. As the cam member 346 is rotated (e.g., by rotating the lock cylinder 342 with the key 354), the enlarged cam 362 is rotated to move the cam surface 366 relative to the cam follower 374. When a recessed portion of the cam surface 366 is aligned and in contact with the cam follower 374, the cam follower 374 moves (e.g., slides) away from the fingers 370 (to the right in FIG. 21). As the cam follower 374 moves away from the fingers 370, the wings 378 of the cam follower 374 allow the proximal ends 386 of the fingers 370 to spread apart so that the distal ends 390 of the fingers 370 move toward each other. When a protruding portion of the cam surface 366 is aligned and in contact with the cam follower 374, the cam member 346 pushes (e.g., slides) the cam follower 374 toward the fingers 370 (to the left in FIG. 21). As the cam follower 374 moves toward the fingers 370, the wings 378 of the cam follower 374 push the proximal ends 386 of the fingers 370 together so that the distal ends 390 of the fingers 370 are spread apart from each other (i.e., in the direction of arrows E).

As shown in FIGS. 18 and 23, the security apparatus 318 also includes a cable mount 394 supported on an end of the body 322 opposite from the engagement mechanism 330. Only part of the cable mount 394 is shown in the figures, but the cable mount 394 may be constructed similar to the cable mount 282 shown in FIGS. 12-17. The cable mount 394 is configured to securely receive a flexible cable (not shown, but similar to the cables 34, 286 described above). The flexible cable can be, for example, wrapped around an immovable object 38 (FIG. 1) to secure the security apparatus 318 to the immovable object 38.

The illustrated security apparatuses 18, 218, 318 provide relatively compact lock and engagement mechanisms that facilitate interfacing with thinner portable electronic devices. In particular, the security apparatuses 18, 218, 318 are designed to engage relatively smaller apertures in portable electronic devices, yet still provide at least the same strength of security as conventional laptop locks. Further, the security apparatuses 18, 218, 318 are physically compact so that a portable electronic device can lay flat on a surface (e.g., table or desk) without interference from the attached security apparatus 18, 218, 318.
