The present invention relates to security apparatuses for securing portable electronic devices and, more particularly, to security apparatuses for use with different interfaces on portable electronic devices.
Security apparatuses are commonly used to secure laptop computers, tablet computers, and other portable electronic devices in place. Some security apparatuses are configured to engage and lock in slots formed in the portable electronic devices. Different portable electronic devices may have different shapes and/or sizes of slots.
In one embodiment, the invention provides a security apparatus for a portable electronic device. The security apparatus includes a lock body, an actuator assembly supported by the lock body, the actuator assembly having an engagement feature configured to rotate between a first position and a second position. The security apparatus further includes a lock tip removably coupled to the lock body. The lock tip is configured to selectively engage the portable electronic device. The lock tip is movable by the actuator assembly between a locked position, in which the lock tip is secured to the portable electronic device, and an unlocked position, in which the lock tip is unsecured from the portable electronic device. Rotating the engagement feature from the second position to the first position locks the lock tip to the lock body and concurrently locks the lock tip to the portable electronic device. Rotating the engagement feature from the first position to the second position unlocks the lock tip from the lock body and concurrently unlocks the lock tip from the portable electronic device.
In another embodiment, the invention provides a security apparatus for a portable electronic device. The security apparatus includes a lock body, an actuator assembly supported by the lock body, the actuator assembly configured to move between a first position and a second position, a lock tip removably coupled to the lock body, the lock tip configured to selectively engage the portable electronic device, wherein the lock tip is movable by the actuator assembly between a locked position, in which the lock tip is secured to the portable electronic device, and an unlocked position, in which the lock tip is unsecured from the portable electronic device, and a retainer coupled to the lock body and separate from the actuator assembly, the retainer configured to move between a holding position in which the retainer holds the lock tip relative to the lock body, and a release position, in which the retainer permits the lock tip to be removed from the lock body.
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.
The illustrated lock body 108 is generally T-shaped having a first portion 120 extending perpendicular to a second portion 124. The first portion 120 is cylindrical in shape, extending between a first end 120A and a second end 120B, and houses a locking mechanism in the form of a lock cylinder 128 (
The security apparatus 100 also includes a cable 144. A first end of the cable 144 is coupled to the lock body 108. In the illustrated embodiment, the first end of the cable 144 is coupled to the second portion 124 of the lock body 108. At a second end (not shown), the cable 144 may be coupled to a relatively stationary object such that when the lock tip 112A is coupled to the lock body 108 and to the portable electronic device 104, the portable electronic device 104 is coupled to the relatively stationary object via the security apparatus 100. The relatively stationary object may be a desk, a chair, a bracket, and the like.
As shown in
The second lengthwise end 156 of the actuator 148 includes a plurality of non-cylindrical engagement features 168, 172 positioned adjacent to one another along the length L of the rotatable actuator 148. The engagement features 168, 172 couple the lock body 108 to the lock tip 112A and assist in transitioning the lock tip 112A between locked and unlocked positions, as described in greater detail below. A first engagement feature 168 has an obround cross-section defined by two semicircles connected via parallel lines. A second engagement feature 172 likewise has an obround cross-section, though rotated a quarter-turn relative to the first engagement feature 168. The second engagement feature 172 has a larger cross-sectional area than the cross-sectional area of the first engagement feature 168 and is located between the first engagement feature 168 and the first lengthwise end 152. As shown in
As shown, the actuator 148 is formed as a single piece and the first and second engagement features 168, 172 are integrally formed with the portion that is coupled to the lock cylinder 128. In other embodiments, the first and second engagement features 168, 172 may be formed separately and attached to the remainder of the actuator 148

As shown in
The illustrated lock tip 112A includes a body 200, first and second expandable fingers 204, 208, and a plunger or paddle 212. The body 200 is cylindrical and is receivable within the lock tip chamber 184. The fingers 204, 208 and the paddle 212 are coupled to and extend outwardly from the body 200. In the illustrated embodiment, the fingers 204, 208 and the paddle 212 extend axially from the body 200 and are generally aligned with the longitudinal axis L when positioned in the lock tip chamber 184. The two fingers 204, 208 are positioned adjacent to and radially outward from the paddle 212. The fingers 204, 208, or tabs or latches, are movable relative to the body 200 between an unlocked position and a locked position by actuation of the paddle 212, as described in greater detail below. An elastomeric element (e.g., an O-ring or rubber band) may surround the fingers 204, 208 to help bias the fingers 204, 208 toward the paddle 212 and toward the unlocked position. An elastomeric shroud 216 may cover the elastomeric element and a portion of the fingers 204, 208 and provide a seal against dirt and debris and acts as a buffer between the lock body 108 of the security apparatus 100 and the portable electronic device 104. When in the unlocked position, the fingers 204, 208 are positioned radially inward so that the fingers 204, 208 are spaced apart from and disengage the portable electronic device 104 (
The illustrated paddle 212 rotates about a rotational axis 220 (
As shown in
Within the chamber 228, the paddle 212 includes an obround recess 240 sized to receive the first engagement feature 168 when the lock tip 112A is positioned in the lock tip chamber 184 of the lock body 208. If the first engagement feature is shaped or sized differently (rectangular, elongated oval, cross, star, etc), the recess 240 is additionally shaped or sized differently to match. The first engagement feature 168 functions as a key in a keyway such that rotation of the first engagement feature 168 results in similar (e.g., matching) rotation of the paddle 212 between the locked and unlocked positions.

Referring back to
In the holding position, the retainer 260 holds the lock tip 112A within the lock tip chamber 184, even when the second engagement feature 172 is not rotated into the pockets 248 of the chamber 228. The lock tip 112A is not locked to the lock body 108 via the retainer 260, as the retainer 260 is readily accessible by anyone. Rather, the retainer 260 holds the lock tip 112A and lock body 108 together to inhibit accidental disassembly. In the release position, the retainer 260 permits removal of the lock tip 112A from the lock tip chamber 184. As shown, the retainer 260 is a crescent-shaped body that is rotatable via user interaction. In the release position, the crescent does not block the lock tip chamber 184 and therefore permits insertion and removal of the lock tip 112A from the lock tip chamber 184 if the engagement feature 172 is rotated out of the pockets 248. In the holding position, the crescent is rotated so that it blocks the lock tip chamber 184, thereby inhibiting the removal of the lock tip 112A from the lock tip chamber 184. As shown, the retainer 260 includes a slot 264 that can be gripped by a finger, fingernail, coin, or screwdriver to facilitate rotation of the retainer 260.
As shown in
In operation, to lock the portable electronic device 104 with the security apparatus 100, a user fastens the cable 144 around a relatively stationary object with the security apparatus 100 in the unlocked position. The user selects an appropriate lock tip 112A, 112B, 112C to engage the slot 104A of the portable electronic device 104. Using the alignment features 192, 252 as a guide, the lock tip 112 is inserted into the lock tip chamber 184, thereby engaging the first engagement feature 168 with the paddle 212 and inserting the second engagement feature 172 into the chamber 228. The user moves (e.g., rotates) the retainer 260 into the blocking position to hold the lock tip 112A within the lock tip chamber 184. The fingers 204, 208 of the lock tip 112A are inserted into the slot 104A of the portable electronic device 104. The user actuates the locking mechanism by rotating the key 136 within the key opening 132 of the lock cylinder 128, thereby rotating the actuator 148 and engagement features 168, 172. The first engagement feature 168 rotates the paddle 212 from the unlocked position to the locked position, expanding the fingers 204, 208 and locking the lock tip 112A to the portable electronic device 104. At the same time, the second engagement feature 172 rotates into the pockets 248, thereby locking the lock tip 112A to the lock body 108.
To unlock the portable electronic device 104 from the security apparatus 100, the user rotates the key 136 within the lock cylinder 128 from the first, locked position to the second, unlocked position, thereby rotating the actuator 148 and engagement features 168, 172. The first engagement feature 168 rotates the paddle 212 from the locked position to the unlocked position, retracting the fingers 204, 208 radially inward, thereby unlocking the lock tip 112A from the portable electronic device 104. At the same time, the second engagement feature 172 rotates out of the pockets 248, thereby unlocking the lock tip 112A from the lock body 108. With the retainer 260 rotated into the holding position, the lock tip 112A remains within the lock body 108. If replacing the lock tip 112A is desired, the retainer 260 is moved (e.g., rotated) to the release position and the lock tip 112A is removable from the lock body 108.
Whereas the security apparatus 100 includes a key-operated lock cylinder 128, the security apparatus 300 includes a locking mechanism in the form of a combination lock 328. The illustrated combination lock 328 requires a four-digit PIN (personal identification number) for locking and unlocking the security apparatus 300. When the correct PIN is entered into the combination lock 328, a manual interface 332 is movable relative to the lock body 308. In the illustrated embodiment, the manual interface 332 is a slider. In other embodiments, the manual interface 332 may be a push-button, a lever, a rotatable dial, and the like. The illustrated slider 332 is constrained to linear motion along a lengthwise direction 338 relative to the lock body 308. When the PIN is scrambled and incorrectly identified, the slider 332 is not movable relative to the lock body 308.
The actuator assembly 316 includes the slider 332 and additionally includes an actuator 348 coupled to the slider 332. The actuator 348 includes a first portion forming a pin or cam 350 and a second portion forming a follower 354 having a slot 358. As shown, the cam 350 of the actuator 348 and the slider 332 are integrally formed as a single component such that translation of the slider 332 results in translation of the cam 350. The cam 350 may include one or more cam members 370 that interact with the cam follower 354. The cam follower 354 has one or more slots 358 (as shown, two slots 358), formed as arcuate slots that curve around the circumference of the cam follower 354. In other embodiments, the shape of the cam follower slot can be alternatively shaped, such as purely helical, etc. The slots 358 are also obliquely angled relative to the longitudinal axis 360 so that the slots 358 helically wind around the cam follower 354. As shown in
The cam follower 354 additionally includes first and second engagement features 368, 372, similar to the engagement features 168, 172 (
When the slider 332 is movable (by way of the correct PIN in the combination lock 328), movement from a first, locked position to a second, unlocked position involves translating the slider 332 along the lengthwise direction 338 of the actuator 348. As the slider 332 is coupled to the cam 350, the cam 350 is likewise translated relative to the lock body 308. The cam 350 rotates the cam follower 354 as the cam members 370 translate axially within the oblique slots 358, thereby also rotating the first and second engagement features 368, 372 from an unlocked position to a locked position. Rotating the first and second engagement features 368, 372 to the locked position locks the lock tip 112A to the portable electronic device 104 and to the lock body 308.
In some embodiments, the slider 332 may be biased toward the unlocked position and may be held in the locked position by sliding the slider 332 and scrambling the PIN, thereby holding the slider in the locked position. In other embodiments, the slider 332 may be unbiased toward either the locked position or the unlocked position and instead is moved between locked and unlocked positions by hand as permitted based on the correct PIN. In further embodiments, the slider 332 may be biased toward the locked position and may be held in the unlocked position temporarily when connecting one of the lock tips 112A, 112B, 112C. In some embodiments, the slider may be replaced by an alternative mechanism interface such as a rotation dial, a switch lever, or a button.
In operation, to lock the portable electronic device 104 with the security apparatus 300, a user fastens the cable 344 around a relatively stationary object. The user selects an appropriate lock tip 112A, 112B, 112C to engage the slot 104A of the portable electronic device 104. The PIN is set so that the locking mechanism is in the unlocked position. The locking mechanism needs to be actuated and held in the unlocked position in order to positively insert the lock tip 112A. Using the alignment features 392, 252 as a guide, the lock tip 112A is inserted into the lock tip chamber 384, thereby engaging the first engagement feature 368 with the paddle 212 and inserting the second engagement feature 372 into the chamber 228. The user moves (e.g., rotates) the retainer 360 into the blocking position to hold the lock tip 112A within the lock tip chamber 384. The fingers 204, 208 of the lock tip 112A are inserted into the slot 104A of the portable electronic device 104. The user actuates the locking mechanism by entering the PIN into the combination lock 328 and translating the slider 332, thereby translating the cam 350, and rotating the cam follower 354 and the engagement features 368, 372 coupled to the cam follower 354. The first engagement feature 368 rotates the paddle 212 from the unlocked position to the locked position, expanding the fingers 204, 208 and locking the lock tip 112A to the portable electronic device 104. At the same time, the second engagement feature 372 rotates into the pockets 248, thereby locking the lock tip 112A to the lock body 308. The user scrambles the combination lock 328 to prevent the slider 332 from moving from the locked position to the unlocked position by an unauthorized user.
To unlock the portable electronic device 104 from the security apparatus 300, the user enters the PIN into the combination lock 328, moving the slider 332 from the first, locked position to the second, unlocked position, thereby translating the cam 350 and rotating the cam follower 354 and engagement features 368, 332. The first engagement feature 368 rotates the paddle 212 from the locked position to the unlocked position, retracting the fingers 204, 208 radially inward, thereby unlocking the lock tip 112A from the portable electronic device 104. At the same time, the second engagement feature 372 rotates out of the pockets 248, thereby unlocking the lock tip 112A from the lock body 308. With the retainer 360 rotated into the holding position, the lock tip 112A remains within the lock body 308. If replacing the lock tip 112A is desired, the retainer 360 is moved (e.g., rotated) to the release position and the lock tip 112A is removable from the lock body 308.
