DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0046] Referring now to the accompanying drawing figures wherein
like reference numerals denote like elements throughout the various
views, one or more embodiments of a merchandise display security
system for displaying and protecting an article of merchandise are
shown. More particularly, embodiments of a merchandise display
security system are provided for monitoring whether an article of
merchandise is attached to the security system. As shown and
described herein, embodiments of the merchandise display security
system include electronics for monitoring a proximity sensor in
contact with the article of merchandise and for activating an alarm
in the event that the article of merchandise is separated from the
security system.
[0047] Embodiments of the present invention are directed to
merchandise display security systems for displaying and protecting
an article of merchandise M supported on a merchandise display or
other support surface, for example, a tabletop, counter, shelf or
the like, located in a retail store, from theft or unauthorized
removal. The article of merchandise M is typically a display model
or sample of handheld electronic merchandise, such as a mobile
(e.g., cellular) telephone, Smartphone, gaming console, personal
data assistant (PDA), global positioning system (GPS) device,
e-reader, tablet, media player, digital video recorder (DVR),
handheld camera, and the like, for customers to examine. The
illustrated embodiments of merchandise display security systems are
configured for use with a digital camera. However, the article of
merchandise M may be any desired type of handheld, portable
electronic merchandise or device. The article of merchandise M may
be attached to the merchandise display security system 20 and
displayed in a powered state so that potential purchasers are able
to evaluate the operation and features of the merchandise when
making a decision whether to purchase the item. In the embodiments
illustrated herein, the article of merchandise M may be a digital
camera having an internal power source. For example, the article of
merchandise M may be provided with one or more internal batteries
that may be replaced when discharged, or recharged to retain a
charge of electrical power. For example, the article of merchandise
M may have a removable battery door 22 (see, e.g., FIG. 3) for
accessing an internal battery compartment.
[0048] FIGS. 1-10 illustrate one embodiment of a merchandise
display security system 10 including a sensor 25. The merchandise
display security system 20 comprises a base 40 (see, e.g., FIG. 6
and FIG. 7) configured for removably supporting the sensor 25 and
the article of merchandise M thereon in a display orientation (see,
e.g., FIG. 8). The base 40 and the sensor 25 are electrically
connected with a cable 60, as shown in FIG. 8. In some embodiments,
the cable 60 comprises a length of an elastic or otherwise
extensible electrical cable. As shown herein, at least a portion of
the cable 60 may be a helical coil cable similar to a conventional
telephone handset cord comprising an outer sheath made of an
insulating material surrounding a plurality of conductors for a
purpose to be described hereafter. In one embodiment, one end of
the cable 60 comprises a connector 24, for example a modular
registered jack (RJ) telephone plug, configured to electrically
connect the conductors of the cable to the base 40. The other end
of the cable 60 may be "hard-wired" into the sensor 25. However, if
desired, the other end of the cable 60 may comprise a connector,
for example likewise a modular (RJ) telephone plug, configured to
electrically connect the conductors of the cable to electronics
disposed within the sensor 25.
[0049] The base 40 (sometimes also referred to as a "puck" or
"medallion") comprises a body configured for removably supporting
the sensor 25 and the article of merchandise M in the desired
display orientation on a merchandise display or other support
surface, for example, a tabletop, counter, shelf or the like,
located in a retail store. The base 40 may be any display stand,
module, pedestal or the like that permits a potential purchaser to
examine an article of merchandise in an unpowered state and/or to
operate an article of merchandise in a powered state. If desired,
the base 40 and the sensor 25 may be formed with opposing geometry,
or alternatively, provided with one or more magnets for aligning
the sensor and the article of merchandise M in the desired display
orientation. The base 40 may be any desired shape and configuration
depending on the article of merchandise M to be supported. For
example, FIG. 6 shows that the base may include a slot 26 or
opening for receiving the sensor therein. Moreover, the base 40 may
be electrically connected to an external power source for powering
its electrical components and/or may include an internal power
source, such as a battery. For example, FIG. 7 shows that the base
may include a movable battery door 43 for accessing a battery
compartment, a speaker or piezoelectric device 44 for emitting an
audible signal, and pressure-sensitive adhesive 47 for securing the
base to the merchandise display or support surface. Alternatively,
or in addition, the base 40 could be secured to the merchandise
display or support surface using any desired technique, such as
with adhesives and/or fasteners.
[0050] In one embodiment, the merchandise display security system
20 further includes alarm electronics or circuitry. In the
illustrated embodiments, the alarm electronics is integrated into
the base 40. The alarm electronics may be electrically coupled to
the cable 60. The alarm electronics may be further electrically
coupled to a power cord for receiving power from an external power
source, and/or to an internal power source, such as a battery,
disposed within the base 40. Furthermore, the alarm electronics may
include circuitry for receiving a security signal from the sensor
25 in response to a security event, such as when the sensor has
been removed from the article of merchandise M or the cable 60 has
been severed, cut or disconnected. The alarm electronics may
further include functionality for providing an audible and/or
visible alarm.
[0051] In one embodiment, the alarm electronics (e.g., housed
within base 40) may be electrically connected to the sensor 25 by
conductors disposed within one or more cables, such as cable 60. As
such, the alarm electronics may operate to monitor the state of a
sensor switch, for example, a conventional proximity or limit
switch 30 provided on the sensor 25 (see, e.g., FIG. 4), through
cable 60 and to activate an audible and/or visible alarm in the
event that the article of merchandise M is separated from the
sensor. For example, a sense loop may be defined through the cable
60 to the sensor 25 such that when the sense loop is interrupted
(e.g., cable 60 is severed, cut or disconnected, or sensor 25 is
removed from article of merchandise M), the alarm electronics is
configured to detect this interruption. Base 40 may further
comprise a sensor switch 42, for example, a conventional proximity
or limit switch that is configured to engage the merchandise
display or support surface when the base is disposed on the
merchandise display or support surface. Sensor switch 42 may be
electrically connected to the alarm electronics, which operate to
monitor the state of switch 42 and to activate an audible and/or
visible alarm in the event that base 40 is separated from the
merchandise display or support surface in an unauthorized
manner
[0052] Base 40 may also comprise a communication port 48 for
permitting communication with electronics housed within the base to
arm and disarm the alarm electronics. With the alarm electronics
disarmed, an authorized person can separate the article of
merchandise M from the sensor 25, disconnect the cable 60 from the
base 40, and/or separate the base from the merchandise display or
support surface. For example, the communication port 48 may
communicate via a wireless signal, such as via infrared (IR)
communication, with a key 80, as illustrated in FIG. 9B. In some
embodiments, the key 80 and the electronics may exchange a security
code via communications port 48, and the alarm electronics may be
armed or disarmed when the security codes match. In one embodiment,
the communication port 48 is accessible when the article of
merchandise M and sensor 25 are supported on the base 40. It is
understood that the communication port 48 may be located at any
desired position on the base 40, or at another accessible location
provided on the merchandise display or support surface.
[0053] In some embodiments, the merchandise display security system
20 also includes a merchandise bracket 45 that is configured for
coupling to the article of merchandise M. (see, e.g., FIG. 2 and
FIG. 3). The merchandise bracket 45 is further configured to be
releasably secured to the sensor 25 (see, e.g., FIG. 4). In
particular, the merchandise bracket 45 may include a quick-release
mechanism for releasing the sensor 25 from the article of
merchandise M. The sensor 25 may be disengaged from the merchandise
bracket 45 such that only the merchandise bracket is engaged with
the article of merchandise M. Where the article of merchandise M
includes a battery compartment (e.g., accessible through battery
door 22), the merchandise bracket 45 is sized and configured to
allow access to the battery compartment with the merchandise
bracket attached to the article of merchandise M when the sensor 25
is removed from the merchandise bracket and the article of
merchandise. Notably, FIG. 3 illustrates that the merchandise
bracket 45 is sized and configured so as to not block or otherwise
impede access to the battery door 22 of the article of merchandise
M while the merchandise bracket is secured to the article of
merchandise.
[0054] Thus, unlike conventional systems, devices and methods that
require fasteners and cumbersome techniques for attaching the
sensor 25 to the article of merchandise M, the battery compartment
is readily accessible by an authorized person. In particular, the
authorized person is not required to disassemble the sensor 25 or
to remove any fasteners in order to detach the sensor and access
the battery compartment. Therefore, retailers are able to replace
batteries of an article or merchandise M in a more efficient
manner, thereby allowing potential purchasers to examine and
operate the article of merchandise M in a powered state. In
addition, the batteries of the article of merchandise M are not
readily removable when the sensor 25 is engaged with the
merchandise bracket 45, which prevents the batteries from being
removed from the article of merchandise by an unauthorized
person.
[0055] In one embodiment shown in FIG. 2, the merchandise bracket
45 may be configured to attach to the article of merchandise M with
a fastener 46. The fastener 46 may be configured to engage an
internally threaded tripod hole provided on the article of
merchandise M. In some embodiments, the fastener 46 has a
proprietary head that is configured to mate with a proprietary tool
bit 48 or other suitable special tool, as illustrated in FIG. 3.
The merchandise bracket 45 could be further secured to the article
of merchandise M with an adhesive, such as with pressure sensitive
adhesive 50, which may resist rotation of the merchandise bracket
relative to the article of merchandise. It is understood that the
merchandise bracket 45 and/or sensor 25 may include other
anti-rotation means, such as an anti-rotation bracket.
[0056] As discussed above, the merchandise bracket 45 is configured
to releasably engage the sensor 25. In one embodiment shown in FIG.
4, the merchandise bracket 45 and the sensor 25 are slidably
engaged with one another. In this regard, the merchandise bracket
45 may include one or more slots 52 configured to engage the
sensor, and the sensor may include one or more undercuts, recesses,
slots or the like 54 that are configured to engage the merchandise
bracket. In one embodiment, the sensor 25 and merchandise bracket
45 may engage one another in dovetail engagement (see, e.g., FIG.
4). Furthermore, an outer peripheral surface of the merchandise
bracket 45 may be visible when engaged with the sensor 25 and may
substantially correspond to an outer peripheral surface of the
sensor to define a uniform profile when the merchandise bracket is
secured to the article of merchandise M. Thus, the merchandise
bracket 45 may be slid into locking engagement with the sensor 25
(see, e.g., FIG. 5A). When engaged with the merchandise bracket 45,
the sensor 25 is sized and configured to block access to the
battery door 22 (see, e.g., FIG. 5B). The sensor 25 could block any
compartment or number of compartments typically located on the
underside (i.e., bottom) of the article of merchandise M. As such,
unauthorized persons are unable to access the battery door 22 or
other compartment on the bottom of the article of merchandise M. It
is understood that the sensor 25 and merchandise bracket 45 may be
any desired configuration for facilitating engagement and
disengagement thereof. For example, the merchandise bracket 45
could simply be an externally threaded stud that engages the
internally threaded tripod hole and is configured to extend from
the article of merchandise M to releasably engage the sensor 25. In
another example, FIG. 16 shows an embodiment where the merchandise
bracket 45 may be disposed internally within the sensor 25 such
that the only exposed peripheral surface of the merchandise bracket
is at the open end of the sensor when the sensor and the
merchandise bracket are secured to an article of merchandise M.
[0057] In some embodiments, a key may be required to remove the
sensor 25 from the merchandise bracket 45. For example, a
mechanical and/or electronic key may be used to disengage the
sensor 25 from the merchandise bracket 45. FIG. 10 shows one
embodiment of a key 70 configured to unlock the sensor 25 from the
merchandise bracket 45. In this example, the sensor 25 may include
a quick-release mechanism 72 (see, e.g., FIG. 11 and FIG. 12),
which may be spring biased, and that is disengaged by the key 70,
thereby allowing the sensor 25 and the merchandise bracket 45 to
disengage from one another. The quick-release mechanism 72 may be
configured to lock the sensor 25 on the merchandise bracket 45
without being disengaged with a key 70. FIG. 11 shows an example of
such a quick-release mechanism 72 with the housing of the sensor 25
removed for purposes of clarity. In this embodiment, the
quick-release mechanism 72 includes one or more engagement
member(s) 75 engaged with the merchandise bracket 45 that are
spring biased such that engagement of the key 70 with the
quick-release mechanism disengages the engagement member(s) from
the merchandise bracket. For example, engagement of the key 70 with
the quick-release mechanism 72 may be used to bias the engagement
member(s) 75 downwardly out of engagement with the merchandise
bracket 45, thereby allowing the sensor 25 to slide laterally
relative to the merchandise bracket. Thus, insertion of the key 70
through an opening 49 at an accessible end of the merchandise
bracket 45 engages the quick-release mechanism 72, which disengages
the merchandise bracket from the sensor 25 (see, e.g., FIG. 12).
Once disengaged, the sensor 25 may be removed from the merchandise
bracket 45. The engagement member(s) 75 may be spring biased
upwardly such that sliding the senor 25 onto the merchandise
bracket 45 once again causes the sensor to automatically engage the
merchandise bracket. It is understood that the key 70 may be any
suitable key, for example a proprietary key that is sized and
configured to be inserted to engage the quick-release mechanism 72.
Moreover, it is understood that the quick-release mechanism 72 may
take many different forms, including electrical and/or mechanical
latching and locking mechanisms.
[0058] FIG. 9A and FIG. 9B illustrate an example of steps to remove
the sensor 25 from the base 40 and the article of merchandise M. In
this example, an authorized person may utilize key 70 to disengage
the connector 24 of cable 60 from the base 40. Thus, the connector
24 and the base 40 may be in a locked configuration when engaged
with one another and unlocked by the key 70. A second key 80 may be
used to arm and/or disarm the alarm electronics in the base 40 by
communicating with port 48, as discussed above. The alarm
electronics disposed within the base 40 and/or the sensor 25 could
be disarmed prior to the cable 60 being removed from the base.
However, the cable 60 need not be removed in all instances, such as
when an authorized person desires to simply replace or recharge
batteries for the article of merchandise M. When disarmed, the
authorized person can remove the sensor 25 from the merchandise
bracket 45 and the article of merchandise M without triggering an
alarm signal. Moreover, it is understood that the same key may be
employed to unlock the connector 24 of the cable 60 of sensor 25
from the base 40 and to arm and/or disarm the alarm electronics, in
addition to disengaging the sensor from the merchandise bracket
45.
[0059] FIGS. 13-15 illustrate another embodiment of a merchandise
display security system 100 according to the invention. The
merchandise display security system 100 is similar to those
discussed above with the exception that a secondary sensor 102 may
be used to secure a camera lens 104 or other removable component of
the article of merchandise M. The secondary sensor 102 may be a
proximity or pressure switch similar to those described above. The
secondary sensor 102 may be electrically connected to the base 40
and associated electronics such that unauthorized removal of the
sensor 25 from the camera lens results in the alarm electronics
generating a security signal. FIG. 15 shows an example of the
sensor 25 engaged with the merchandise bracket 45.
[0060] It is also apparent from the aforementioned embodiments that
the sensor 25 and associated cable 60 may be removed from the
merchandise bracket 45. In contrast, with some conventional sensors
either only the cable may be removed from the sensor, or the entire
sensor is removed from the article of merchandise. As such,
embodiments of the present invention allow retailers to readily
remove the sensor 25 and cable 60 such that the article of
merchandise M may be stored when no longer desired to be on
display, such as when a retail store is closed.
[0061] FIGS. 17-20 illustrate another embodiment of a sensor 125
for a merchandise display security system 120 according to the
invention. The security system 125 is similar to the embodiments
described above in that a sensor 125 and associated cable 160 are
configured to be readily removed from the article of merchandise M
via a quick-release feature. In some embodiments, the sensor 125 is
also coupled to a power adapter, cord or cable 162 for supplying
electrical power to the article of merchandise M. For example, the
power cable 162 may include a connector 164 configured to
releasably engage an input port of the article of merchandise M.
Thus, the sensor 125, cable 160, and power cable 162 may be
configured to provide power to the article of merchandise M when
the power cable 162 is engaged with an input port of the article of
merchandise. The sensor 125, cable 160, and power cable 162 may
also be configured to define a sense loop therethrough such that
severing, cutting and/or removing either cable 160 or power cable
162, or removal of the sensor 125 may result in the generation of a
security signal as described above.
[0062] The sensor 125 may be configured to be removably supported
on a base 140. The base 140 may be operably engaged with the sensor
125 in a variety of manners. For example, the base 140 may be
hardwired to the sensor 125 and include conductors configured to
cooperate with conductors within the cable 160. Alternatively, the
cable 160 may plug into a port 161 provided in the base 140, such
as shown in FIG. 19. The base 140 may be in electrical
communication with an external power source. The base 140 may
further include an internal power source configured to provide
power to the base in the event that power from an external power
source is interrupted or lost. In some embodiments, the sensor 125
and/or base 140 include a pressure switch 143 or other mechanism,
such as a proximity switch or limit switch, to detect unauthorized
removal (see, e.g., FIG. 20). The base 140 may also be configured
to generate a security signal in response to such unauthorized
removal. Thus, should the connector 124 be removed from the base
140, the sensor 125 removed from the article, a cable cut, and/or
the base removed from a power source, the base may be configured to
generate a security signal.
[0063] The sensor 125 may include alignment features 142 (e.g.,
magnets) that are configured to align and interact with
corresponding alignment features on the base 140. For example, the
base 140 may include at least one internal magnet or magnetically
attractable material disposed on the upper surface that is
configured to operably engage a magnet 142 or magnetically
attractable material on the sensor. In particular, the magnet(s) or
magnetically attractable material of the base 140 is configured to
align with and engage the magnet(s) or magnetically attractable
material of the sensor 125 so that the sensor is removably
supported on and secured to the base.
[0064] In another embodiment, the base 140 includes a window, port
148 or the like that is configured to receive a wireless security
signal for arming and/or disarming the base. The port 148 may be
disposed on an upper surface of the base 140. In some embodiments,
the port 148 may be covered by the sensor 125 when the sensor is
supported on the base 140. Furthermore, the wireless security
signal may be any suitable signal configured to arm and/or disarm
the alarm electronics disposed within the base 140 and/or the
sensor 125, as previously discussed.
[0065] In one embodiment, the security system 120 also includes a
quick-release feature for removing the sensor 125 from a
merchandise bracket 145. In this regard, FIGS. 21-27 show an
embodiment of a sensor 125 that is configured to rotatably engage a
merchandise bracket 145. The merchandise bracket 145 may be secured
to the article of merchandise M with a pressure-sensitive adhesive
or other suitable technique, while the sensor 125 may be removably
secured to the merchandise bracket. In one embodiment, the
merchandise bracket 145 is configured to be received by the sensor
125 and secured thereto. For example, FIGS. 23-25 show that the
merchandise bracket 145 may include one or more engagement members
146 that are configured to engage corresponding engagement members
150 provided on the sensor 125. In the illustrated example, the
engagement members 146 of the merchandise bracket are protrusions,
while the engagement members 150 of the sensor are slots. As shown
in FIGS. 23-25, the merchandise bracket 145 and sensor 125 may
include a plurality of engagement members 146, 150, including
engagement members that are radially opposite one another. It is
understood that any variety of engagement members 146, 150 may be
employed to align and engage the merchandise bracket 145 and sensor
125, and thus, the embodiments illustrated herein are exemplary and
not intended to be limiting in any manner
[0066] With reference to FIG. 26, the sensor 125 may further
include a rotatable quick-release mechanism 152. The rotatable
quick-release mechanism 152 is configured to rotate relative to the
housing of the sensor 125. For example, FIG. 21 shows that the
rotatable quick-release mechanism 152 may include a head 154 that
is configured to be engaged by a tool for manual rotation. FIG. 26
also shows that the rotatable quick-release mechanism 152 may also
include one or more engagement features 167. In the illustrated
example, the rotatable quick-release mechanism 152 includes a pair
of engagement features (e.g., protrusions) 167 that extend
outwardly and are radially opposite one another. Thus, rotation of
the rotatable quick-release mechanism 152 causes the engagement
features 167 to also rotate. FIG. 22 and FIG. 26 further show that
the sensor 125 may include a sensor switch 130, similar to that
previously described. The merchandise bracket 145 may define an
opening 163 that is configured to receive the sensor switch 130
(see, e.g., FIG. 27). Thus, when the merchandise bracket 145 and
sensor 125 are secured to one another, the sensor switch 130 is
configured to extend through the opening 163 so as to be able to
contact the article of merchandise M (see, e.g., FIG. 22).
[0067] FIG. 28 shows an enlarged view of the merchandise bracket
145. The merchandise bracket 145 may include an adapter plate 165
that is secured to a base portion 166. The adapter plate 165 and
base portion 166 may be secured together using any desired
technique, such as with a fastener 168. The base portion 166 may
define an outer surface that is configured to be secured to an
article of merchandise M. As noted above, the merchandise bracket
145 may define at least one opening, including an opening 163 for
receiving the sensor switch 130. In one embodiment, a pair of
openings are defined, and one of the openings is configured to
receive a portion 170 of the adapter plate 165 therein (see, e.g.,
FIG. 22). The portion 170 of the adapter plate 165 received within
the base portion 166 may facilitate alignment therebetween as well
as resisting rotation between the adapter plate and the base
portion.
[0068] In addition, FIG. 27 and FIG. 28 show that the adapter plate
165 may include one or more engagement features 172 that are
configured to align with and engage the engagement features 167 of
the rotatable quick-release mechanism 152. In this regard, the
engagement features 172 may include a pair of radially opposite
slots that are configured to align with the engagement features 167
of the rotatable quick-release mechanism 152. A lip 174 may be
defined between the engagement features 172. In one embodiment, a
medial portion of the adapter plate 165 may extend outwardly away
from the base portion 166 to define a raised radial surface (see,
e.g., FIG. 28). The lip 174 may extend radially about the
circumference of the raised surface between the engagement features
172. The rotatable quick-release mechanism 152 is configured to be
partially received within the raised surface such that the raised
surface surrounds the engagement features 167. When the engagement
features 167, 172 are aligned with one another, the engagement
features 167 may be received by the engagement features 172, and
rotation of the rotatable quick-release mechanism 152 causes the
engagement features 167 to extend below and engage the lip 174.
When the engagement features 167 engage the lip 174, the sensor 125
and merchandise bracket 145 are secured to one another and cannot
be removed with an axial force. As such, rotation of the rotatable
quick-release mechanism 152 in one direction may result in securing
the sensor 125 and merchandise bracket 145 together, while rotation
in an opposite direction may result in disengaging the sensor from
the merchandise bracket. In some embodiments, the quick-release
mechanism 152 may include a fastener, locking mechanism, or the
like that is configured to lock the sensor 125 relative to the
merchandise bracket 145 to prevent the sensor from rotating
relative to the merchandise bracket.
[0069] FIGS. 29-35 illustrate another embodiment of a sensor 225
for a merchandise display security system and a merchandise bracket
245 implementing a quick-release feature 252 according to the
invention. The sensor 225 may also be configured for use with the
base 140 previously described. In this embodiment, the sensor 225
and merchandise bracket 245 are also configured to rotatably engage
and disengage one another. As also previously discussed, the sensor
225 may include a cable 260 and a power cable 262. The merchandise
bracket 245 may be configured to be attached to the article of
merchandise M with a pressure-sensitive adhesive, although other
securement techniques could be employed in other embodiments.
[0070] FIG. 32 and FIG. 33 show enlarged views of the merchandise
bracket 245. As shown, the merchandise bracket 245 may include one
or more engagement members 246. A plurality of engagement members
246 may be disposed about the outer perimeter of the merchandise
bracket. By way of example only and not limitation, four engagement
members 246 are shown in FIG. 32 and FIG. 33. In addition, the
engagement members 246 may define slots 252 (FIG. 33), which may,
for example, be L-shaped in configuration. Moreover, the
merchandise bracket 245 may include a raised surface, or ridge 248
extending outwardly from an inner surface thereof. The raised
surface may extend circumferentially on the inner surface. In one
embodiment, the merchandise bracket 245 includes an outer portion
259 and an inner portion 261, wherein the inner portion is
configured to rotate relative to the outer portion. The inner
portion 261 may be configured to rotate in both a clockwise and
counterclockwise direction, and may be configured to rotate at
least partially about the inner circumference of the outer portion
259. The inner portion 261 may include the ridge 248, while the
outer portion 259 may include the engagement members 246. The inner
portion 261 may include one or more engagement features 263 that
are configured to rotate relative to the engagement members 246 as
well as engage the engagement members 246 to facilitate attachment
between the inner portion 261 and the outer portion 259. In one
example, the engagement features 263 are configured to rotate below
the engagement members 246. Sufficient clearance is provided
between the engagement features 263 and engagement members 246 to
allow for rotation therebetween, but little if no axial movement
relative to one another.
[0071] In one embodiment, the merchandise bracket 245 may include a
sensor switch extender 250, which may also be provided on the inner
portion 261 of the merchandise bracket. The sensor switch extender
250 may be movable relative to the merchandise bracket 245 and
configured to align with a sensor switch 230 provided on the sensor
225. When the sensor 225 and merchandise bracket 245 are secured to
one another, the sensor switch 230 is configured to bias the sensor
switch extender 250 outwardly relative to merchandise bracket for
contacting the article of merchandise M. Thus, in the event that
the article of merchandise M is removed from the merchandise
bracket 245 in an unauthorized manner, the sensor switch 230 will
be activated via actuation of the sensor switch extender 250.
[0072] FIGS. 34-36 illustrate enlarged views of the sensor 225
according to one embodiment of the invention. The sensor 225
includes at least one engagement member 254. As shown, the sensor
225 may include a plurality of engagement members 254 disposed
about the outer perimeter of the sensor. The sensor 225 may also
include a raised surface, or ridge 256 defined about the outer
perimeter and between the engagement members 254. The engagement
members 254 and ridge 256 may be defined on the sensor 225, or the
sensor may include an adapter plate 257 secured to the sensor
including such features (see, e.g., FIG. 36). The adapter plate 257
may be secured to the sensor 225 using any suitable technique, such
as a pressure-sensitive adhesive and/or fasteners.
[0073] The sensor 225 is configured to be releasably secured to the
merchandise bracket 245. In this regard, the sensor 225 is
configured to be inserted into the merchandise bracket 245 such
that the engagement features 254 are disposed adjacent to the outer
perimeter of the merchandise bracket and the ridge 248 is disposed
radially inwardly of the ridge 256. Thus, the merchandise bracket
245 is configured to receive at least a portion of the sensor 225
therein. The sensor 225 is also positioned adjacent to the inner
portion 261 of the merchandise bracket 245. The sensor 225 is
configured to be rotated relative to the merchandise bracket 245 to
engage and disengage the merchandise bracket. For example, the
sensor 225 may be configured to rotate in conjunction with the
inner portion 261 in one direction (e.g., counterclockwise) so that
the engagement members 254 engage engagement members 246. In
particular, the engagement members 246 define slots 252 that are
configured to receive the engagement members 254. The inner portion
261 and the sensor 225 may be configured to rotate in unison. When
in engagement, the sensor 225 and merchandise bracket 245 are
secured together and may not be removed from one another without
disengaging the sensor from the merchandise bracket. The sensor 225
may be disengaged by rotating the sensor in an opposite direction
(e.g., clockwise) relative to the merchandise bracket 245 until the
engagement members 254, 246 disengage one another. The sensor 225
and/or merchandise bracket 245 may further include at least one
blocking member 258 (FIG. 32) that is configured to only allow
rotation of the sensor 225 in one direction. In other words, when
the engagement members 254, 246 are not in engagement with one
another, the blocking member 258 is configured to abut an
engagement member 254 when rotated in a direction that does not
result in engagement with an engagement member 246.
[0074] Therefore, in light of the aforementioned discussion, it is
apparent that various techniques may be employed for securing a
sensor to a merchandise bracket and for quickly releasing the
sensor from the merchandise bracket. The quick-release feature does
not require disconnecting cables or disassembly of the sensor in
order to separate the sensor from the article of merchandise. In
addition, the quick-release feature may facilitate changing
batteries in the article of merchandise, storing the article of
merchandise when not in use, or servicing the article of
merchandise.
[0075] Embodiments of a merchandise display security system
including at least the aforementioned features have been shown and
described herein for purposes of illustrating and enabling the best
mode of the invention. Those of ordinary skill in the art, however,
will readily understand and appreciate that numerous variations and
modifications of the invention may be made without departing from
the spirit and scope of the invention. Accordingly, all such
variations and modifications are intended to be encompassed by the
appended claims.
