DETAILED DESCRIPTION

[0034] FIGS. 1A to 3 show a first embodiment of a holder assembly H comprising a carrier 2 with a carrier housing 20 at which several holder devices 1 are mounted. Each holder device 1 comprises one elongated holding member in the form of a bottom wire 1B at which goods to be displayed at the point of sale may be hanged and arranged in a row one behind the other. Goods hanging at the bottom wire 1B may be slid along the bottom wire 1B to a removal position at a free end 110B of the bottom wire 1B where goods may be removed from the bottom wire 1B. Above the bottom wire 1B a holder part in the form of a top wire 1A is provided. The top wire 1A is spaced apart from the bottom wire 1B and carries a tag 5 at its end projecting from the carrier 2. The tag 5 comprises a front face 5A at which information on the goods to be hanged on the bottom wire 1B may be displayed. A bottom margin of the tag 5 comprises a wire opening 50 through which the free end 110B of the bottom wire 1B extends.

[0035] The top wire 1A of each holder device 1 is fixedly connected via fastening portions 12A to the carrier housing 20. The fastening portions 12A are provided at an end of the top wire 1A distant from the tag 5 and are formed by two parallel wire base portions. The fastening portions 12A are fixed to a carrier beam 22 of the carrier housing 20. The holder devices 1 are fixed at the carrier beam 22 in such a way that the holder devises 1 are equally spaced and their top and bottom wires 1A, 1B run in parallel to each other. The carrier housing 20 furthermore integrates at least two hook-shaped fastening elements 21 for fastening the holder assembly H to a point-of-sale display arrangement. Via the fastening elements 21 the carrier 2 and thus the complete holder module provided by the holder assembly H may be hanged to such a display arrangement.

[0036] Whereas a top wire 1A of each holder device 1 is rigidly fixed to the carrier 2, each bottom wire 1B is mounted displaceable with respect to the top wire 1A. Each bottom wire 1B may thus be displaced from a first position shown in FIGS. 1A to 3 downwards to a second position in which a distance between the top wire 1A and the bottom wire 1B is increased. The displaceable bottom wire 1B is fixed to a trigger element in the form of an elongated trigger bar 3. The trigger bar 3 is arranged perpendicular to the holder devices 1 and in parallel to the carrier beam 22. Along its direction of extent the trigger bar 3 comprises several equally spaced slot-like connecting receptacles 31 for mounting wire end sections 10B of the bottom wires 1B to the trigger bar 3. A wire end section 10B of each bottom wire 1B is angled away from a straight wire section 11B of the respective bottom wire 1B at which the goods are to be arranged. Each wire end section 10B is plugged into a connecting receptacle 31 at a top surface 30 of the trigger bar 3. In the configuration shown in FIGS. 1A to 3 the trigger bar 3 comprises more connecting receptacles 31 then the holder devices 1 are mounted to the carrier 2. Namely, just every second connecting receptacle 31 at the trigger bar 3 is occupied. The different connecting receptacles 31 of the trigger bar 3 allow for arranging different numbers of holder devices 1 at the carrier 2 and allow for assembling a holder assembly H in different configurations. For example, a holder assembly with less (e.g., three) holder devices 1 compared to the holder assembly H of FIGS. 1A to 3 may be provided with the same trigger bar 3.

[0037] The trigger bar 3 is arranged in parallel to the carrier beam 22 to which the top wires 1A of the different holder devices 1 are fixed. By several spring elements in the form of pressure springs 4 the trigger bar 3 is biased (upwards) towards a straight wire section 11A of the top wire 1A at whose end the tag 5 is arranged. To restrict a displacement of the trigger bar 3 and thus of the bottom wire 1B fixed to it a stopper element 10A is a provided at each holder device 1. These stopper elements 10A block the trigger bar 3 from an upward movement beyond the position shown in FIGS. 1A to 3 in which the bottom wire 1B of each holder device 1 is located in its first position at a predefined distance to the associated top wire 1A.

[0038] In order to remove a good from the bottom wire 1B of a holder device 1, namely from the wire section 11B of the bottom wire 1B, the bottom wire 1B has to be pushed or pulled downwards so that goods can be moved past the tag 5 at the free end 110B of the bottom wire 1B. For this displacement of the bottom wire 1B a consumer/user may pull a good hanging at the bottom wire 1B downwards or the consumer/user may exert a pushing force to the top surface 30 of the trigger bar 3. In either way the trigger bar 3 with the bottom wire 1B is to be displaced into a second position in order to allow for a removal of a good from the bottom wire 1B.

[0039] Due to the pressure springs 4 acting on the trigger bar 3 a bottom wire 1B of a holder 1 is automatically pushed back to its first position once the good is removed and a manual force is no longer applied to the bottom wire 1B or the trigger bar 3 by a user/consumer pushing or pulling the bottom wire 1B and/or the trigger bar 3 downwards (via a good hanging at the bottom wire 1B and/or applying a force directly to the bottom wire 1B and/or the trigger bar 3).

[0040] As shown in the cross-sectional view of FIG. 3 the trigger bar 3 with the bottom wire 1B in its second position actuates on an electronic detection element in the form of a micro-switch 6 accommodated in a housing interior 200 of the carrier housing 20. This micro-switch 6 is connected via connecting leads 72 to electronics 8 of the holder assembly H. By actuating on the micro-switch 6 a displacement of the bottom wire 1B downwards to its second position may be electronically detected. This electronic detection of the bottom wire 1B being displaced to the second position allows for a determination that at least one good is it to be removed or already has been removed from the bottom wire 1B. Since a removal of goods from the bottom wire 1B, in addition to sliding a good along the wire section 11B to the free end 110B along a direction of removal R1, requires pushing or pulling the bottom wire 1B and the trigger bar 3 downwards in a direction of displacement R2 perpendicular to the direction of removal R1 (see FIG. 3) thereby necessarily actuating the micro-switch 6, a removal of at least one good from the bottom wire 1B can be securely electronically detected.

[0041] The bottom wire 1B can also be rigidly fixed to the top wire 1A so that the bottom wire 1B as whole is not linearly displaceable downwards but may be swivelled about a swivel axis S provided at a connection between the bottom and top wires 1A, 1B. Here, the free end 110B may be swivelled downwards upon a removal of a good. The swivel movement of the bottom wire 1B also exerts a downward force on the trigger bar 3 in order to actuate the microswich 6. The rigid connection between the bottom wire 1B and the top wire 1A and thus the swivel axis S may be provided at the end of the bottom wire 1B near the carrier 2. For example, the rigid connection is provided by welding, in particular by spot-welding, the wire section 10B of the bottom wire 1B and the projection element 10A of the top wire in this case the element 10A of the top wire 1A thus not forming a stopper element but a connection element for the two wires 1A, 1B. Due to a flexibility inherent to the (single) bottom wire 1B the bottom wire 1B may in this case still be displaced to a second position relative to the top wire 1A about the swivel axis S defined at in the region the element 10A of the top wire 1A. Such a swivel movement about the swivel axis S also results in the trigger bar 3 being moved downwards and in thus actuating the micro-switch 6.

[0042] The electronics 8, which are fixed to the carrier housing 20 by a fastening structure 80, for example a bold or screw and a nut, are further configured to emit at least one signal based on one or more actuations of the microswitch 6. A signal may be an acoustic signal or an optical signal. At least one signal can for example be emitted every time the bottom wire 1B is displaced to its second position. For example, each time the bottom wire 1B is displaced into its second position an acoustic signal is emitted in order to indicate a (potential) removal of at least one good from the bottom wire 1B. Such an acoustic signal may be received by a receiver unit 9 shown in FIG. 1A. For detecting the acoustic signal the receiver unit 9 may comprise a microphone. The receiver unit 9 furthermore comprises an evaluation logic determining how many acoustic signals are received from the holder assembly H within a given period of time. The receiver unit 9 may thus determine a frequency of received acoustic signals and compare them against a signal threshold value. This signal threshold value corresponds to a threshold value for a removal frequency for the removal of the goods from the holder assembly H. In case a determined frequency of detected acoustic signals (and thus a removal frequency) exceeds the signal threshold value an illicit removal of goods by a shoplifter is considered to take place and an alarm signal is emitted by an alarm device D coupled to the receiver unit 9. In an alternative embodiment the signal received by the receiver is inaudible and transmitted wirelessly, i.e., as a radio wave signal. The electronics of the holder assembly H may thus be configured to transmit radio frequencies for informing the remote receiver unit 9 of a displacement of the bottom wire 1B to its second position. A wireless communication between the holder assembly H and the receiver unit 9 may be based on a wireless communication standard, like Bluetooth, IEEE 802.11 or LTE. The receiver unit 9 is configured to receive radio frequencies and emit an alarm signal in case the received signals over time exceed a threshold value as outlined above.

[0043] In the alternative or in addition to the alarming scenario described above the electronics 8 itself may include an evaluation logic for determining at least one of a frequency the bottom wire 1B is displaced to its second position and a time the bottom wire 1B stays in the displaced second position. In case the electronics 8 determine that a (frequency or time) threshold value is exceeded by the determined frequency or the measured time an acoustic alarm signal and/or a visual alarm signal is generated and emitted by the electronics 8 at the holder assembly H. For this purpose the electronics 8 may include at least one of a speaker and a lamp or diode, in particular an LED.

[0044] FIG. 4A to 8B show a second embodiment of a holder assembly H. In contrast to the first embodiment of FIGS. 1A to 3 the holder assembly H of FIGS. 4A to 8 comprises several holder devices 1 with displaceable tags 5 functioning in each case as a displacing element for displacing the respective bottom wire 1B to its second position upon removal of good from the bottom wire 1B.

[0045] The tag 5 of the embodiment of FIGS. 4A to 8B is hinged to transverse journal portions 110A provided at the end of the top wire 1A of a holder device 1. To these journal portions 110A a hinge portion 51 of the tag 5 is mounted so that the journal portions 110A define a pivot axis about which the tag 5 may be pivoted from a blocking position, as for example shown in FIGS. 7 and 8A, to a removal position, as for example shown in FIG. 8B. The hinge portion 51 of the tag 5 connects a front tag part with the front face 5A with a rear lobe portion 52 extending towards the bottom wire 1B.

[0046] In the first position of the bottom wire 1B the tag 5 with its lobe portion 52 is the blocking position in which the lobe portion 52 reaches into an adjustment path along which a good has to be slid along the bottom wire 1B towards the free end 110B of the bottom wire 1B. When a good, like a blister pack, hanging at the bottom wire 1B shall be removed from the bottom wire 1B and is thus pushed or pulled along the direction of removal R1 towards the free end 110B of the bottom wire 1B an upper part of the good (at which an opening is provided through which the bottom wire 1B extends) has to mandatorily contact the lobe portion 52 of the tag 5. Upon then sliding the good further towards the free and 110 B of the bottom wire 1B the good exerts a force on the lobe portion 52 toward the free end 110B. Due to this force the tag 5 is pivoted about the pivoting axis of the journal portions 110A of the bottom wire 1B. By pivoting the tag 5 the lobe portion 52 is (with its edge facing the wire section 11B of the bottom wire 1B) pushed against the bottom wire 1B and thus moved to a pushing position. In this pushing position the lobe portion 52 acts on the bottom wire 1B pushing it downwards to its second position upon further pivoting of the tag 5 in the clockwise direction along a swivel direction R3 (see FIG. 6). A force which is exerted on a good hanging at the bottom wire 1B in order to slide the good to the end 110B of the bottom wire 1B is thus partially converted by the hinged tag 5 with its lobe portion 52 into a displacing force exerted on the bottom wire 1B for displacing it from the first position to the second position. The displacement of the bottom wire 1B effected by the lobe portion 52 results in a displacement of the trigger bar 3 to which all the bottom wires 1B are mounted. Thereby the micro-switch 6 is actuated so that a removal of a good may be electronically detected and automatically evaluated as stated above.

[0047] When the good to be removed from the bottom wire 1B reaches the free end 110B of the bottom wire 1B the tag 5 is in a release position in which the lobe portion 52 no longer acts on the bottom wire 1B and thus no longer pushes the bottom wire 1B in its second position. Furthermore, the tag 5 also does no longer block a removal of the goods from the bottom wire 1B. By the springs 4 acting on the trigger bar 3 the bottom wire 1B is then pushed back upwards to its first position.

[0048] FIGS. 9A to 12 show a third embodiment of a holder assembly H in which each holder device 1 is provided with an immovable displacing element at the end of each top wire 1B. Each displacing element comprises a wedge-shaped displacing body 53 and a tag front part with the front face 5A attached or integrated to it. The wedge-shaped displacing body 53 is tapered towards the bottom wire 1B and comprises a wire slot 531 through which the free end 110B of the bottom wire 1B extends through the wedge-shaped displacing body 53 when the bottom wire 1B is in its first position.

[0049] The wedge-shaped displacing body 53 defines a rearward inclined contact surface 530 facing the carrier 2. Along this inclined contact service 530 a good hanging on the bottom wire 1B has to slide in order to get past the wedge-shaped displacing body 53. By sliding the good along the inclined contact surface 530 of the wedge-shaped displacing body 53 the good to be removed is forced downwards. The good thus will be automatically displaced with respect to the top wire 1A at which the wedge-shaped displacing body 53 is fixed to. The wedge-shaped displacing body 53 hence at least partially converts a force exerted on the good in order to move the good to the front of the bottom wire 1B (towards its free end 110B) to a force directed downwards. Thereby, for example, pulling a good towards the free end 110B of the bottom wire 1B necessarily results in the good to be forced downwards when the good comes into contact with the inclined contact surface 530 of the wedge-shaped displacing body 5.

[0050] Due to the connection between the good and the displaceable bottom wire 1B at which the good hangs this downward directed force results in a displacement of the bottom wire 1B with respect to the top wire 1A. The bottom wire 1B will thus necessarily be displaced into its second position in order to get the good past the wedge-shaped displacing body 53. A removal of one or more goods from the bottom wire 1B thus mandatorily results in a movement of the bottom wire 1B and the trigger bar 3 accompanied by an actuation of the micro-switch 6. Accordingly, the electronics 8 accommodated within the carrier housing 20 of the carrier 2 of the holder assembly Has the case may be together with a receiver unit 9 and an alarm device Dallow for determining at least one of a removal frequency at which goods are removed from the bottom wire 1B and a time the bottom wire 1B is in its second position in which goods may get past the wedge-shaped displacing body 53 and thus may be removed from the bottom wire 1B as stated above.

[0051] Naturally, holder assembly H of FIGS. 1A to 3, 4A to 8B and 9 to 12 may also provided with less holder devices than shown. In particular a holder assembly H may be provided just comprising a single holder device 1. In this respect the carrier 2 and in particular its carrier housing 20 may be significantly smaller. The same applies to the trigger bar 3 which then may just comprise a single receptacle 31 to which the bottom wire 1B is fixed or at which the bottom wire 1B (configured to be swivelled about swivel axis S at its rear and) may act on the trigger bar 3.

[0052] FIGS. 13A, 13B and 13C show an embodiment of a holder assembly H which comprises a single holder device 1. The top wire 1A of the holder device 1 includes two parallel wire sections and the single bottom wire 1B extends beneath the top wire 1A in the middle of those two wire sections. Both the top wire 1A and the bottom wire 1B are fixed at their rear ends to a carrier 2.

[0053] The bottom wire 1B of the holder assembly H of FIGS. 13A to 13C is again displaceable with respect to the top wire 1A so that it may be displaced from a first position shown in FIGS. 13A to 13C to a second position upon a removal of goods from the bottom wire 1B. In the embodiment shown in FIGS. 13A to 13C the free end 110B of the bottom wire 1B may be swivelled about the swivel axis S at the rear end of the bottom wire 1B downwards in order to allow the removal of goods from the bottom wire 1B at the free end 110B.

[0054] In order to ensure that just one good at the time is removed from the bottom wire 1B its wire section 11B near free end 110B forms are recessed portion 111B. This recessed portion 111B is V-shaped and hinders that more than one good may be moved past the recessed portion 111B to the free end 110B.

[0055] For electronically detecting displacement of the bottom wire 1B to its second position the holder assembly H of FIGS. 13A to 13C comprises an electronic detection element including a magnet 1100B and a reed switch 6R. The magnet 1100B is provided at the free end 110B of the bottom wire 1B, whereas the reed switch 6R is mounted to the top wire 1A opposite the free end 110B of the bottom wire 1B. Due to a change of position of the free end 110B and thus the magnet 1100B provided at the free end 110B a magnetic field applied to the reed switch 6R changes resulting in a generation of an electrical signal. For example, contacts of the reed switch 6 are open when the bottom wire 1B is in its first position and thus a magnetic field of the magnet 1100B of the bottom wire 1B is present. When the bottom wire 1B with its free end 110B is swivelled downwards and thus displaced into its second position for a removal of a good from the bottom wire 1B the distance between the magnet 1100B to the reed switch 6R increases. When the magnetic field provided by the magnet 1100B is thus the no longer present near the reed switch 6R the contacts of the reed switch 6 return to a normal closed position thereby generating an electric signal. This electric signal is thus indicative for the displacement of the bottom wire 1B to its second position. After the good has been removed from the bottom wire 1B the bottom wire 1B, due to its flexibility, returns to its first position in which the magnet 1100B at the free end 110B is closer to the reed switch 6R of the top wire 18. The contacts of the read switch 6 are thus forced again to an open position.

[0056] For pivotably fixing a tag to the holder device 1 of FIGS. 13A to 13 C the front end of the top wire 1A comprises tag fastening portion 15A. The tag fastening portion 15A in the exemplary embodiment of FIGS. 13A to 13C therefore comprises a transverse journal to which a tag may be clipped.

[0057] It is clear that the electronic detection of a displacement of the bottom wire 1B to its second position as outlined above for the holder assembly H of FIGS. 13A to 13C may also be implemented by a holder assembly H being configured such that the contacts of the reed switch 6R are normally open and held closed by the magnet 1100B in the first position of the bottom wire 1B. In this case the contacts return to a normal open position upon displacement of the bottom wire 1B with its magnet 1100B to the second position. The reed switch 6R may also be provided at the bottom wire 1B and the magnet 1100B may be provided at the top wire 1A without departing from the present disclosure. Furthermore, a holder device 1 of FIGS. 13A to 13C including a reed switch 6R may also be provided at a holder assembly H of FIGS. 1A to 3, 4A to 8B and 9 to 12. Accordingly, a holder assembly may be provided with several holder devices 1 as shown in FIGS. 13A to 13C which are then mounted to a single carrier.

[0058] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be implemented in another embodiment, even if not specifically shown or described. The same elements may also be varied in one or more ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
