Embodiments of the present invention relate generally to merchandise display security systems for displaying and protecting an article of merchandise from theft.
Retailers routinely display relatively small, expensive, handheld electronic merchandise, such as mobile (e.g. cellular) telephones, iPods, game consoles, personal data assistants (PDAs), and the like, for customers to examine before making a purchase. Retailers often desire the handheld electronic merchandise to be powered as well so that a potential purchaser can test the operation and functions of the merchandise. At the same time, the retailer does not want the article of merchandise to be stolen or removed from the display area by an unauthorized person. Accordingly, the article of merchandise being displayed is attached to a merchandise display security device that monitors and protects the article of merchandise from removal or theft. Such a merchandise display security device typically includes a sensor housing to which the article of merchandise is attached that houses a sensor for monitoring whether the article of merchandise remains attached to the sensor housing. In the event that the article of merchandise is detached from the sensor housing, an audible or visible alarm is activated to alert store personnel to the situation.
Oftentimes it is desirable for a retailer to provide power to the merchandise for facilitating use of the device on display as well as charging. For example, a power adaptor cord may be used to power the handheld electronic merchandise, or alternatively, to charge an internal battery that powers the article of merchandise in the absence of an external power source (including an internal power source of the merchandise display security device). Furthermore, the merchandise may be physically secured to the display with a tether. The tether may not only provide physical security, but may also serve to provide power to the sensor and the displayed merchandise. However, these displays oftentimes require specialized tethers and adapters that are hardwired to the sensor.
Accordingly, there exists a need for a merchandise display security system for displaying and protecting a powered article of merchandise from theft. There exists a further need for a merchandise display security device that includes a more cost efficient and less complicated means for providing power to the sensor and/or article of merchandise.

The base may include a base portion and an optional pedestal portion extending upwardly from the base portion. The article of merchandise M may be any number of electronic devices, such as a mobile (e.g. cellular) telephone, iPod, game console, personal data assistant (PDA), tablet, portable computer, and the like. The article of merchandise M is attached to the merchandise display security device 10 in a manner so as to allow customers to examine and operate the merchandise before making a decision to purchase.
As explained in greater detail below, embodiments of the present invention are generally directed to reduced cost merchandise security devices, namely an alarm unit, for protecting merchandise, such as cellular telephones, on display for sale in retail stores. The alarm unit may utilize a power supply cable for the merchandise as the power cable and tether of the alarm unit. As a result, the alarm unit reduces manufacturing and material costs and reduces the complexity of installation and use of the merchandise security device.
The free end of the power supply cable 20 has a connector 22 that is configured to be received within the recess 12 and releasably engage a connector 16 on the attachment side 14 of the alarm unit 10. As shown in
The power supply cable 20 is electrically coupled to the alarm unit 10 and the alarm unit in turn provides power to the merchandise M through a power adapter cable 18 that is hard-wired to a power output port 17 of the alarm unit. As used herein, the term “power adapter cable” is intended to include any cable, adapter (also commonly referred to as a “pigtail”) or cord containing one or more conductors for providing electrical power to a handheld electronic article of merchandise, for example a mobile (cellular) telephone. The power adapter cable 18 may be provided with a variety of different connectors 19 at the free end thereof to accommodate the various types of power input jacks (e.g. cellular telephone power input jacks) provided on different articles of merchandise M. For example, the connector 19 may be a male micro-USB connector. In addition to providing electrical power to the alarm unit 10 and to the merchandise M, the power supply cable 20 may serve as a mechanical tether holding the alarm unit and the merchandise to a secure display fixture. The alarm unit 10 is configured to activate an alarm in the event the power supply cable 20 is severed, and/or in the event the power adapter cable 18 is severed or removed (unplugged). An internal power source (e.g., a battery) may provide power to activate the alarm in the event that the power supply cable 20 is severed. In one embodiment, the internal power source is a rechargeable battery that is recharged by power supplied by the power supply cable 20.
Use of the second embodiment is advantageous for installation in retail stores in which power “brown-outs” are likely. In the event of a power brown-out, alarms of merchandise security devices 10 according to the first embodiment may be activated, which can be very annoying for customers. The alarms of merchandise security devices 30 according to the second embodiment, however, are not activated when electrical power from the power supply cable 50 is interrupted. Instead, the alarm of the second embodiment of the merchandise security device 30 is activated only if power to the alarm unit 30 and/or the merchandise M is interrupted beyond the connectors 52, 42. In particular, the alarm may be activated in the event that connector 42 of the lanyard 40 is removed (unplugged) from the plug 52 of the power supply cable 50, the lanyard 40 is severed, and/or the power adapter cable 38 is severed or removed (unplugged) from the merchandise M.
According to one embodiment, electronics are disposed within the merchandise display security device 10, 30 that monitor whether an article of merchandise M is attached to the merchandise display security device.

In one embodiment, the attachment side 14, 34 is relatively planar and includes a proximity switch, limit switch, pressure switch or the like. A relatively planar rear surface of the article of merchandise M is securely attached to the attachment side 14, 34, for example by a relatively thin layer of an adhesive 33, such as double-sided pressure sensitive adhesive (PSA), in a known manner. Regardless, the switch may be configured to engage the rear surface of the article of merchandise M and may be electrically connected to the electronics disposed in the merchandise display security device 10, 30 either directly, or alternatively, through an electrical circuit disposed within the merchandise display security device. The status of the switch may change between an un-activated, or “non-alarming,” state when the article of merchandise M is securely attached to the merchandise display security device and an activated, or “alarming,” state when the article of merchandise is separated from the merchandise display security device.
In some embodiments, the merchandise display security device 10, 30 comprises an internal power source, and/or is electrically connected to an external power source. In either case, the power adapter cable 18, 38 is electrically connected to the power source to provide power to the article of merchandise M through the connector 19, 39 of the power adapter cable that is electrically connected to the power input port provided on the article of merchandise. As will be readily appreciated by those skilled in the art, the opposite end of the power adapter cable 19, 39 is electrically connected to the merchandise display security device 10, 30. As a result, the power adapter cable 19, 39 both mechanically and electrically connects the article of merchandise M to the merchandise display security device 10, 30.
The lanyard 40 may comprise a plurality of conductors. At least some of the conductors of the lanyard 40 may be electrically connected at one end to the electronics disposed within the merchandise display security device 30, and are electrically connected at the other end to the power supply cable 50. At least some of the other conductors of the lanyard 40 may be electrically connected at one end to an internal power source within the merchandise display security device 30, or alternatively, to an external power source, and electrically connected at the other end to the power output port 37. Moreover, the power adapter cable 38 may contain at least a pair of conductors that are electrically connected to a corresponding pair of conductors of the lanyard 40. The conductors of the power adapter cable 38 are electrically connected to the article of merchandise M through the connector 39 at an end of the power adapter cable. As such, the power adapter cable 38 functions to provide electrical power from the internal or external power source to the article of merchandise M.
As such, the merchandise display security device 10, 30 is positioned inline between the OEM power supply cable and the article of merchandise. The connection of the OEM power supply cable, alarm unit, and power adaptor cable provides an electrical connection that is detectable by the alarm unit, such as by providing a sense loop therethrough. For example, the merchandise display security device may be configured to activate an alarm when the connector 19, 39 of the power adaptor cable 18, 38 is removed from the article of merchandise, or the opposite end of the power adaptor cable is removed from the alarm unit. In addition, the merchandise display security device 10 may be configured to alarm when the OEM power supply cable 20 is removed from the alarm unit. Similarly, the alarm unit may be configured to activate an alarm in the event that the connector 42 coupled to the lanyard is removed from the OEM power supply cable at one end or removed from the alarm unit at an opposite end. Moreover, the alarm unit may be configured to activate an alarm in response to cutting of the power adaptor cable 19, 39 and/or the lanyard 40.
