[0049] While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
[0050]
[0051] To prevent sweeping, or theft, of all of the products on the display hook 104, the rotating handle 108 includes components designed to monitor the removal of merchandise from the display hook 104.
[0052] The main rotating handle housing 110 houses a rotor 114, which is shown in more detail in the perspective view of
[0053] As shown in the embodiment of
[0054] The embodiment of the rotor 114, shown in the perspective view of
[0055] That electrical contact is facilitated by the interaction between the rotor 114 and the stator 116.
[0056]
[0057]
[0058] Referring to
[0059] The sloped barriers 138 on the stator 116 are designed such that they prevent rotation of the rotor 114 in one direction. More particularly, when the rotating handle 108, and more particularly the main rotating handle housing 110, is rotated in a first direction, the high ends 144 of the two sloped barriers 138 come into contact with the rotor 114 at the two arcuate openings 130 to prevent the rotor 114 from rotating with the main rotating handle housing 110. Rotation of the main rotating handle housing 110 in this first direction is for loading merchandise onto the display hook 104.
[0060] When the rotating handle 108 and the main rotating handle housing 110 are rotated in a second direction opposite the first direction, the two arcuate openings 130 first contact the low end 142 of the two sloped barriers 138 such that the rotor 114 is not prevented from rotating with the main rotating handle housing 110. As the main rotating handle housing 110 is rotating in this second direction, the rotor 114 and attached second contact 120 are rotating as well. This causes the two fingers 168 on the second contact 120 to rise and fall as the downward-facing bumps 170 come into contact with the a plurality of raised portions 140 on the two curved walls 136 of the stator 116. When the two fingers 168 rise due to this contact with the raised portions 140, the two upward-facing bumps 172 of the second contact 120 come into contact with the first contact 118 attached to the main rotating handle housing 110. The resulting electrical connection between the first and second contacts 118, 120 is detected by circuitry on the circuit board 154. Rotation of the main rotating handle housing 110 in this second direction is for removing merchandise from the display hook 104. Thus, with the stator 116, as shown, having four raised portions 140 on each curved wall 136, there would be eight electrical connections between the first and second contacts 118, 120 for each rotation of the rotating handle 108 in the second direction.
[0061]
[0062] When the rotating handle 108 is rotated, the MCU 202 wakes up from sleep mode. In such an instance, MCU port P0.0 detects the trigger signal (rotation handle rotates), and counts pulses, or the electrical connections between first and second contacts 118, 120 generated by each rotation of the rotating handle 108. The MCU 202 outputs an audio, visual, or radio signal according to the following conditions. For example, if the number of accumulated electrical connections or pulses in a predetermined time period (e.g., 10 seconds) exceeds a threshold value (e.g., 24, which for the embodiments shown indicates three full rotations of the rotating handle 108), the MCU 202 outputs an audio, visual, wired or wireless alarm signal. The alarm signal, which indicates that three or more items have been removed from the display hook 104 in a short period of time, which may indicate a theft in progress. In another example, the number of pulses generated by each rotation operation, during the predetermined time period, is greater than one but less than 24, MCU 202 outputs an audio, visual or radio signal indicative of a non-theft condition or that the MCU 202 is entering sleep mode. If there are no pulses for a predetermined period of time (e.g., 0.6 seconds at Port P0.0), the MCU 202 determines that the current rotating operation of the rotating handle 108 has been completed.
[0063] In a particular embodiment, the visual indicator is an LED, where the LED flashes synchronously with the audio signal when an alarm is triggered, or flashes synchronously with no audio alarm. The MCU 202 may also cause the LED flash to flash in a specific pattern, possibly in concert with an audio signal, to signal a low voltage warning.

[0065] In the diagram of
[0066] In addition to providing the loss prevention benefits of the anti-sweeping hook 100 described above, some anti-sweeping hooks, such as anti-sweeping hook 300 (also referred to herein as “hook 300”) of the system of
[0067] As illustrated in
[0068] Typically, the alarm box 301 is on site or local to the hook 300. Further, while a single hook 300 is illustrated, the alarm box 301 can communicate with a plurality of hooks 300.
[0069] The alarm box 301 can receive inventory loss issues such as discussed with regard to hook 100 previously and/or inventory management information such as from hook 300.
[0070] Hook 300 is similar in many respects to hook 100. With reference to
[0071] The rotating handle 308 has internal electronic componentry that is different than that of rotating handle 108. The electronic componentry may provide to prevent sweeping, or theft, of the productions on the display hook as discussed above. However, the electronic componentry also provides the ability to track and communicate inventory information.
[0072] The handle 308 includes a main rotating handle housing 310 that is connected to the coil 306 by a central fastener 312.
[0073] Similar to the handle housing 110, handle housing 310 houses a rotor 314, which is shown in detail in
[0074] The handle housing 310 carries a first set of contacts 328, 329 and a second set of contacts 330, 331 that are in communication with a circuit board 354. The first set of contacts 328, 329 are part of a first circuit while the second set of contacts 330, 331 are part of a second circuit. Notably, contacts 328, 329 are isolated from one another and contacts 330, 331 are isolated from one another. When the handle housing 310 is rotated, contacts 328-331 rotate with the handle housing.
[0075] Each of the contacts 328, 329, 330, 331 have a plurality of radially extending contact lobes 328a, 329a, 330a, 331a. All of the lobes 328a, 329a of the first set of contacts 328, 329 are substantially equally angularly spaced apart while all of the lobes 330a, 331a of the second set of contacts 330, 331 are substantially equally angularly spaced apart. Further, the first set of contacts 328, 329 has a same number of lobes as the second set of contacts 330, 331.
[0076] In operation, the lobes 328a, 329a are radially spaced from the rotational axis of the handle 308 a same distance as upward facing bumps 326 of contact fingers 322 and the lobes 330a, 331a are radially spaced from the rotational axis of the handle 308 a same distance as upward facing bumps 327. As such, when the rotating handle housing 310 rotates relative to the stator 316 and/or rotor 314, the first and second contacts 318, 320 will selectively complete the first and second circuits.
[0077] In this example, the stator 316 is rotationally fixed to the housing 302. More particularly, stator 316 has nibs 340 (
[0078] The rotating handle housing 310 is configured to engage the rotor 314, similar to handle 108, such that when the rotating handle housing 310 rotates in the first direction, the rotating handle housing 310 engages rotor 314 and causes it to rotate in the first direction relative to stator 316. However, when the rotating handle housing 310 is rotated in an opposite second direction, the stator 316 engages the rotor 314 such that the rotor 314 will not rotate relative to the stator 316, but the rotating handle housing 310 will rotate relative to the stator 316 and 314, which are rotationally fixed to one another.
[0079] Thus, as the rotating handle housing 310 rotates in the first direction, the second contact 320 will selectively connect and disconnect inner contacts 330, 331 as the fingers 327 selective contact opposed ones of the lobes 330a, 331a that are 180 degrees apart from one another. This will selectively make and break the inner circuit that includes contacts 330, 331.
[0080] However, as noted above, when the rotating handle housing 310 is rotated in the first direction, the rotor 314 rotates with the rotating handle housing 310 relative to stator 316. Because the rotor 314 rotates with rotating handle housing 310, the rotor 314 does not change its angular position relative to rotating handle housing 310 or contacts 328, 329 carried thereby. As such, the outer circuit that includes contacts 328, 329 stays steady state of either constantly broken or constantly made. Therefore, when the rotating handle housing 310 is rotated in the first direction, the circuit board 354 will sense only changes in the inner circuit that includes contacts 330, 331.
[0081] When the rotating handle housing 310 is rotated in the second direction, rotor 314 is engaged by stator 316 such that rotor 314 remains angularly fixed relative to stator 316. Thus, the angular position of the rotating handle housing 310 now changes with respect to both the rotor 314 and the stator 316. As such, as the rotating handle housing 310 rotates, the inner contacts 330, 331 are repeatedly electrically connected and disconnected from one another by second contact 320 carried by the stator 316 like when rotation occurs in the first direction but now the outer contacts 328, 329 are repeatedly electrically connected and disconnected from one another by first contact 318 carried by the rotor 314. Thus, when the rotating handle housing 310 is rotated in the second direction, the circuit board 354 will sense changes in both the inner circuit that includes contacts 330, 331 as well as the outer circuit that includes contacts 328, 329.
[0082] Notably, when the legs 322, 324 are positioned angularly between adjacent, corresponding, lobes 328a, 329a, 330a, 331a, the corresponding circuits are broken and when the legs 322, 324 contact lobes 328a, 329a, 330a, 331a, the corresponding circuits are made.
[0083] Thus, the circuit board 354 can determine which direction the rotating handle housing 310 is being rotated by determining which circuits are being repeatedly connected and disconnected. Further, by counting the number of connections and disconnections, the degree of rotation of the coil 306 can be determined. As such, by being able to determine how much rotation as well as in which direction, the circuit board 354 can now determine if product is being loaded or unloaded onto the hook 304 as well as how much product is being loaded or unloaded onto the hook 304, e.g. a change in the amount of product on the hook 304.
[0084] Again, this information can also be used to determine if a theft or sweeping event is occurring by determining the rate at which the rotating handle housing 310 is rotated and the direction in which it is being rotated.
