 Security device with sliding holding element

description

The invention relates to a goods security device according to the preamble of claim 1 and a goods security device according to the preamble of claim 28.

Anti-theft devices, in which anti-theft tags are arranged, are used together with anti-theft devices to prevent the unauthorized removal of goods from a secured area. The goods security labels are attached to the goods with appropriate housings. The exits of the secured area are provided with security units that detect a security tag that passes by them and give a corresponding signal. Usually, these are transmitters that receive the resonance frequency emanating from the stimulated goods security label and react to it. Various systems are known, for example acustomagnetic, electromagnetic, radio frequency, high frequency, low frequency systems and the like.

Regardless of the system system technology used, for example, system systems that operate on the basis of electromagnetic (EM), acustomagnetic (AM) or radio frequency (RF) systems, two basic forms of security devices are used. On the one hand, hard tags that are primarily used to secure textiles and the like, which are removed during the checkout process and can be used again and again. On the other hand, activatable and deactivatable adhesive labels which are deactivated during the checkout process and remain on the goods or the packaging of the goods, that is to say are used only once.

Hard tags in the form of a disc with a round or substantially rectangular cross section are known. At least one electromagnetic, acoustical used magnetically or by means of radio frequency or otherwise detectable goods security element. In addition, the known hard tags have a mechanically and / or electronically, electromechanically or otherwise operable lock which, for example, holds an inserted needle until it is unlocked. At the other end of the needle is a needle head. To use these hard tags, which are known per se, in the case of textiles, for example, the needles are arranged so that the goods to be secured protrude so that the needle head is secured on one side against slipping and on the other side the needle is locked in the lock of the hard tag. After the secured goods have been properly purchased, the lock is usually unlocked at the cash register and both the hard label and the needle head with needle are removed. If this does not happen, the goods security element is detected when the checkout area is left and an alarm is triggered.

In a known embodiment of such a goods security device according to DE 103 25 274 A1, the lock of the goods security device is formed in that the fastening means has a mandrel which can be connected to the goods and has a head-like thickening which, with its tip opposite the head-like thickening, passes through an opening into the opening The inside of the housing of the goods security device can be inserted and fixed to the housing in the interior of the housing with a claw-like holding device which forms a further part of the fastening means. Here, a finger-like tool, which is pushed from the outside of the housing towards the claw-like holding device, rotates the position of the claw-like holding device relative to the mandrel and thereby removes the existing connection between the claw-like holding device and mandrel. In order to ensure the rotatability of the claw-like holding device relative to the housing, complex guide and rotating elements are to be provided on the housing and claw-like holding device.

The object of the present invention is therefore to further develop an article security device of the generic type in such a way that ensuring the function of the claw-like holding device when the connection with the mandrel is released is ensured more easily without the security of fixing the dome to the claw-like holding device and its releasability to affect. A white Another task is to ensure safe deactivation of the goods security device.

The solution of the tasks according to the invention results from the characterizing features of claim 1 and claim 28, respectively, in cooperation with the features of the associated preamble. Further advantageous embodiments of the invention result from the subclaims.

The invention according to claim 1 is based on a goods security device, comprising a housing in or on which a detectable goods security element is arranged, and an at least two-part fastening means with which the housing can be detachably fixed to a product or the like, the fastening means having one of the goods connectable mandrel with a head-like thickening, which can be inserted with its tip opposite the head-like thickening through an opening into the interior of the housing and in the interior of the housing with a claw-like holding device forming a further part of the fastening means can be fixed to the housing. Here, a tool can be inserted into the interior of the housing from outside the housing such that it moves parts of the fastening means from a locking position into an open position. Such a generic goods security device is further developed in that the claw-like holding device can be displaced by the tool relative to the mandrel and relative to its starting position and the existing connection between the claw-like holding device and the mandrel can thus be canceled. In contrast to the previously known rotation of the claw-like holding device, a displacement of the claw-like holding device relative to the adjacent parts of the housing requires less precise guides or bearings of the claw-like holding device due to the movement of the tool, as a result of which the design of the assigned housing sections and also of the claw-like ones Holding device is simplified. At the same time, the security of the fixing of the dome to the claw-like holding device or the releasability of the connection between the mandrel and the claw-like holding device is not impaired, so that overall a simplification and reduction of the corresponding manufacturing costs can be achieved. In a preferred embodiment, it is provided that the claw-like holding device is pre-positioned in its starting position for insertion of the dome by positioning elements. Such positioning elements can simply be introduced into the interior of the housing during its manufacture and serve to support and to specify the position of the claw-like holding device in the closed position suitable for inserting the dome. A rough pre-positioning without forcible guidance of the claw-like holding device is usually sufficient to ensure a secure insertion movement of the dome into the claw-like holding device.

In a further embodiment, it is conceivable that the claw-like holding device is positioned on support elements in the closed position in such a way that the tool, after entering the housing, presses on the narrow side of the claw-like holding device and moves the claw-like holding device out of its starting position against the resistance of the positioning elements , This ensures that the security against tampering with the goods security device is particularly high. Since the narrow side of the claw-like holding device can only be recognized very poorly or not at all from the outside of the housing, unauthorized manipulation with tools not specifically provided for this purpose, which must also be moved on a path that is not immediately recognizable, is largely ruled out.

Likewise, the claw-like holding device can permanently destroy one or more of the positioning elements during the displacement due to the action of the tool and thus reach an open position in which the mandrel is released and can be pulled out of the housing. This destruction of the positioning elements clears the way for the displacement of the claw-like holding device without the need for complex guide mechanisms or limitations for the path when the claw-like holding device is displaced. If it is ensured that, with the exception of the positioning elements on the way of the displacement of the claw-like holding device, no housing parts interfere, the claw-like holding device can be safely moved out of the area in which it interacts with the mandrel. This safely releases the mandrel and the goods security device can be detached from the goods. In an advantageous embodiment, it is conceivable that the positioning elements are formed on the housing as projections or bolt-like projecting sections and that the claw-like holding device shears off one or more of the positioning elements during the displacement due to the action of the tool. Such shearing of the positioning elements provided, for example, already during the injection molding of a housing made of plastic, for example, ensures that the goods security device cannot be used again and thus, for example, goods security devices that have been removed from the store without authorization can no longer be used.

It is particularly advantageous for the functional security of the goods security device if the claw-like holding device with guide contours is mounted so as to be linearly movable and guided in linear guide elements of the housing. This ensures a safe movement of the claw-like holding device during the process of opening the claw-like holding device, whereby the detachment of the claw-like holding device from the mandrel can always be ensured by the displacement of the claw-like holding device under the action of the force of the tool. Due to the linear guidance of the claw-like holding device, tilting or tilting of the claw-like holding device during the opening movement is almost impossible, since the linear guides ensure reliable support of the forces exerted by the tool on the claw-like holding device. For this purpose, in a further embodiment, the claw-like holding device can have guide contours arranged on outer edges, which, with housing edges arranged parallel to one another, ensure a slide-like guidance of the claw-like holding device during the displacement due to the action of the tool. If, for example, the claw-like holding device is formed from a sheet metal part, the corresponding guide contours can be provided by corresponding peripheral bevels on individual edges of the claw-like holding device, which are then supported on housing edges or webs introduced into the interior of the housing and the safe linear displacement of the can cause claw-like holding device. A further targeted influencing of the mobility of the claw-like holding device can be achieved by one-sided or both-sided at the end regions of the linear guide Elements are provided which limit the movement of the claw-like holding device. In this way, the displaceability of the claw-like holding device can be specifically controlled and adapted to the required displacement for the release of the dome.

In view of the manipulability and the misuse of previously used goods security devices by unauthorized persons, it is advantageous if the claw-like holding device does not return to the position in which it is on the mandrel after being moved into the position in which it releases the mandrel can be determined, can be reset. This reliably ensures that without destroying the housing, the claw-like holding device cannot be brought back into a position that would allow the goods security device to be used again. The goods security device according to the invention is therefore a goods security device that can only be used once. For this purpose, it can be provided in a further embodiment that the claw-like holding device has a projection which, after the claw-like holding device has been shifted into the open position, hooks on assigned sections in the interior of the housing and secures the claw-like holding device in the open position. This enables the claw-like holding device to be positively fixed in the open position.

A particularly advantageous embodiment provides that the claw-like holding device has an essentially flat holding plate in which a slot-like opening is formed, into which the mandrel can be inserted and secured with shaped elements arranged on the mandrel at the edges of the slot-like opening in the direction of insertion. This ensures that the mandrel in the closed position of the claw-like holding device is held in a form-fitting manner in the slot-like opening, so that the mandrel can no longer be pulled out of the housing of the article security device and can be separated from the article without destroying the mandrel or article. In particular, if, in a further embodiment, the edges of the slit-like opening protrude from the plane of the essentially flat holding plate in the insertion direction, the insertion and locking of the dome in the claw-like holding device can be carried out particularly simply and safely. In a further embodiment, the edges of the slot-like opening can have shaped elements which secure the position of the dome in the direction of extension of the slot-like opening. It could be conceivable here that one-sided or also two-sided recesses are provided in the edges of the slot-like opening, which ensure that after insertion of the dome into the slot-like opening, the mandrel closes the slot-like opening at a precisely defined point in the direction of extension lies, is thereby held positively and / or non-positively in the direction of extension of the slot-like opening and cannot move freely in the direction of extension of the slot-like opening.

It is advantageous if the tool for releasing the fastening means is designed to be elongated in the manner of a finger. This can ensure that the goods security device can be manipulated or detached from the goods only with great difficulty by unauthorized persons with simple manipulations, for example with tools not specifically provided for this purpose. If a corresponding distance is provided within the housing between the inlet opening for the tool and the fastening means or, for example, corresponding baffles are also provided, the fastening means can only be reached and released by guiding a tool on a precisely defined path. If unsuitable tools are used or if they are not guided on the intended tracks, the fastener cannot be reached.

For the intended opening of the article security device, it is advantageous if the finger-like tool for displacing the claw-like holding device is positively guided by means acting outside the housing. For example, a corresponding opening device can be provided for this purpose, into which the goods security device is inserted and precisely positioned. Due to the forced guidance of the finger-like tool, the actuation of the claw-like holding device will always be guaranteed when the fastener is opened, as a result of which the security device is particularly simple and safe to use. A further increase in the security against manipulation can be achieved in that the housing is formed from a hard plastic material. This hard plastic prevents easy manipulation of the housing.

A conceivable embodiment of the article security device according to the invention can be achieved in that the article security device can be used again and again, preferably several times. Such non-deactivatable goods security devices are usually removed from the goods in the checkout area and do not leave the sales area at all. As part of a circulatory system, these anti-theft devices can be used many times.

For this purpose, in an advantageous embodiment, the goods security device has a device acting in the opposite direction against the movement of the claw-like holding device when the connection between the claw-like holding device and the mandrel is released, with which the claw-like holding device returns to its initial position after the dome has been loosened and the tool has been withdrawn is slidable. Such a device ensures that after loosening the dome from the claw-like holding device, the claw-like holding device is moved back into a position that is suitable for reinserting and securing the dome, this is usually the starting position again has already taken claw-like holding device before loosening by the tool. This means that the goods security device must be used again and again.

In a further embodiment, this return movement can be achieved in that the device for pushing the claw-like holding device back into its starting position has a spring-elastic element which is tensioned by moving the claw-like holding device into its open position and is relieved again by the tool after the claw-like holding device has been released. For example, if in a further embodiment the resilient element has a helical spring which is inserted between the claw-like holding device and a housing section and exerts a force against the opening movement of the claw-like holding device, the application of the restoring force is ensured simply and safely. Of course, all other types of elastic shear elements such as spiral springs, torsion springs, reversibly compressible spring elements made of elastic substances or the like, which are fundamentally familiar to the person skilled in the art and should therefore not be listed in more detail here.

If a helical spring is used as the resilient return element, it is also advantageous if the helical spring is held between the claw-like holding device and the housing section in such a way that the helical spring can only compress and expand in the direction of displacement of the claw-like holding device. In this way it can be ensured, for example, by inserting the coil spring into a channel provided on the housing or receiving the coil spring on projections arranged on the housing side and on the claw-like holding device that the coil spring cannot deflect sideways and the spring force is therefore always reliably applied.

Another conceivable embodiment of the article security device according to the invention provides that the claw-like holding device has a contact section for the action of the tool when the claw-like holding device is moved from its closed initial position into the open position. As a result, a contact point which can be influenced and designed in a targeted manner can be created between the claw-like holding device and the tool displacing the claw-like holding device, which allows safe actuation of the claw-like holding device by means of a tool which has been inserted as intended, but at the same time hinders or does not insert or shaped tools as intended. makes their use difficult or even impossible.

Such a contact section can be provided particularly easily if the contact section is a tab angled out of the plane of the claw-like holding device. The claw-like holding device, which is advantageously in the form of a sheet metal part, can have such a tab by bending an edge area, for example in the area in which a properly inserted tool has to abut the claw-like holding device when it is opened. It is further advantageous here if the contact section has such a shape that the claw-like holding device can only be displaced if the contact section with the associated shaped end de of the tool cooperates correctly to move the claw-like holding device from its closed starting position into the open position. If, for example, the contact section and the tool have mating faces which are adapted to one another and come to lie in one another or against one another when the intended use of such a tool, the actuation of the claw-like holding device can thereby be carried out particularly safely. If, on the other hand, a differently shaped tool is used for an improper operation, this mating face can prevent this manipulation tool from interacting securely with the claw-like holding device and moving it from the initial position into the open position.

A further improvement in this security against manipulation can be achieved if, next to the contact section, deflector elements are arranged on the claw-like holding device in such a way that tools which have not been properly inserted into the article security device and are used to manipulate the article security device are rejected and these tools do not expose the claw-like holding device their starting position can be shifted. For example, if, in a further embodiment, the deflector elements are arranged at an angle to the path of movement of tools that have not been properly inserted into the article security device and are used for unauthorized manipulation of the article security device such that these tools slip off the claw-like holding device, the improper operation of the claw-like holding device can be further complicated become. This is also achieved in that manipulation tools of this type usually have to be guided by hand and therefore the necessary point of impact of the manipulation tool on the claw-like holding device is very difficult to achieve. Deflector elements on the claw-like holding device arranged around this necessary point of impact and possibly a configuration of the contact section with a plug face or the like make the improper operation of the claw-like holding device more difficult or impossible.

The invention further relates to an article security device according to claim 28, comprising a housing in or on which a detectable article security element is arranged, and an at least two-part fastening means with which the housing is releasably attachable to a product or the like., wherein the fastening means has a mandrel that can be connected to the product and has a head-like thickening, which can be inserted with its tip opposite the head-like thickening through an opening into the interior of the housing and inside the housing can be fixed to the housing by means of a claw-like holding device forming a further part of the fastening means, and a tool can be inserted into the interior of the housing from outside the housing such that it brings parts of the fastening means from a locking position into an open position. Such a generic goods security device is further developed in that the claw-like holding device can be displaced by the tool relative to the mandrel and relative to its starting position and the existing connection between the claw-like holding device and the mandrel can be canceled, a deactivation section being arranged on the claw-like holding device in such a way that after the claw-like holding device can no longer be displaced from its closed starting position into its open end position, it permanently lies in the area of the article security element in such a way that the article security element no longer gives the intended vibration response even when excited by an excitation field applied from the outside can and the goods security device is thus permanently deactivated. On the one hand, this ensures that the claw-like holding device can only be used once by moving the claw-like holding device.At the same time, after opening the claw-like holding device, the goods securing element is also brought into a state by which an alarm device is triggered, for example, at the exit of a department store when Traversing the security gate with the excitation field created there can be safely avoided and thus improper alarms can be prevented, which can otherwise lead to high customer annoyance. This deactivation takes place inevitably and without any further action on the part of the sales staff, either through an express deactivation process or automatically when the lock is released and, if the deactivation takes place when the goods security device is released from the goods, the sales staff cannot forget them and the negative effects already described Trigger episodes. This also prevents customers from forgetting goods security devices when paying for the goods. Solutions by self-experimentation and in most cases damage the goods, which means that the goods have to be exchanged or replaced by a dealer. Even after leaving the shop, the goods security element is reliably prevented from being triggered incorrectly and can therefore, for example, also remain on the goods sold, without the customer being uncomfortably noticeable when traversing corresponding fields later.

In this embodiment of a goods security device, it is advantageous if the deactivation section is arranged on the rear of the claw-like holding device in an extension of the displacement movement of the claw-like holding device in such a way that the deactivation section in the open position of the claw-like holding device comes to lie at least in sections covering the goods securing element, that the goods security element is no longer able to vibrate freely. By preventing the vibration, which in a further embodiment can be mechanically clamped in sections, a goods security element, for example, in the form of an acustomagnetic security element in the open end position of the claw-like holding device can be prevented from free vibration by the deactivation section due to an excitation field and thus the function of the acustomagnetic goods security element are permanently prevented.

In another embodiment, it is also conceivable that the article security element is an electromagnetic article security element which can be changed in the open end position of the claw-like holding device by the deactivation section with regard to the position of at least parts of the article security element or with regard to the length of at least parts of the article security element. Even small changes of parts of the article security element with regard to their position relative to one another or their length are sufficient to detune the article security element and thereby finally cancel the functionality. This can be done simply by moving the deactivation section.

Furthermore, it is conceivable that the article security element is an article security element with conductor tracks, in which, in the open end position of the claw-like gene holding device of the deactivation section the conductor tracks are cut or cut or otherwise mechanically inoperative. During the displacement of the deactivation section, an edge of the deactivation section, which is designed for this purpose in a knife-like manner, can be passed over the conductor tracks of the article security element under pressure and thereby cut, cut or otherwise mechanically damage the conductor tracks, so that the article security element no longer at least in the actually predetermined form functional and thus mechanically deactivated.

FIGS. 1 a and 1 b and 2 and 3 show a preferred embodiment of the article security device 1 according to the invention, in which a housing is formed from an upper housing part 21 and a lower housing part 2 which do not adjoin one another in the region of a parting line 23 further shown are set. The two housing parts 2, 21 are approximately mirror images z. B. formed from a hard plastic material that can be produced inexpensively, for example, by injection molding.

In a housing 2, 21 of this type, an article security element (not shown further) can be accommodated, for which purpose the receiving space 3 is provided in the housing 2, 21. Such an article security element can work, for example, on an electromagnetic or acustomagnetic basis or on the basis of radio frequencies and is basically known. Therefore, the function of the goods security element should not be discussed further at this point.

In the two top views in FIGS. 1 a and 2, the mode of operation of attaching a corrugated nail 8 to the housing 2, 21 of the goods security device 1 is shown in more detail, which is used to attach a product, not shown, to the housing 2, 21 of the goods security device 1. Such corrugated nails 8 are also known in principle and are described here only to the extent that this is necessary for an understanding of the invention. The corrugated nail 8 here consists of a head 9, which allows a widened fixing of the cylindrical corrugated nail 8 to the goods, not shown, for example by the cylindrical corrugated nail 8 through a buttonhole of a textile or another opening the goods are put through. On the cylindrical portion of the shaft nail 8 z. B. groove-like depressions 10 applied circumferentially and spaced apart, with which the cylindrical portion of the shaft nail 8 interacts in a manner described below with a claw-like holding device 7 of the goods security device 1. For this purpose, the shaft nail 8 is inserted with its tip 24 through an opening 25 in the housing 2, 21 in the insertion direction 26 into the interior of the housing 2, 21 and fixed there by the claw-like holding device 7. So that the corrugated nail 8 does not cause any damage to the goods or a user, a pot-like region 22 is provided opposite the opening 21 on the lower housing part 2, which receives the corrugated nail 8 in its length and completely surrounds it.

In the interior of the housing 2, 21, the claw-like holding device 7 is inserted displaceably relative to the housing 2, 21 and is supported in the direction of insertion 26 of the shaft nail 8 by support elements 12 in the form of corresponding projections and ribs of the housing 2, 21. The claw-like holding device 7 can in principle perform a shift when a tool 5 interacts with the claw-like holding device 7 in the insertion direction 4 in a manner described in more detail below. In the top view it can also be seen that the shaft nail 8, after being inserted in the insertion direction 26, comes to rest in a receptacle 18 in the lower housing part 2, thereby preventing the cylindrical part of the shaft nail 8 from laterally escaping. The displacement of the claw-like holding device 7 is not limited in the position according to FIG. 2. On the top side, the position of the claw-like holding device 7 is secured by the upper housing part 21.

A slot-like opening 13 with curved edges 14 is provided in the claw-like holding device 7 to match the insertion position of the shaft nail 8 in the receptacle 18. As a result, these edges 14 form a parallel slot in the claw-like holding device 7, which is designed just as wide as the diameter of the grooves 10 of the shaft nail 8. As a result, the edges 14 of the claw-like holding device 7 in the position according to FIG. 1a can positively fix the shaft nail 8 in its position along the insertion direction 26 on the housing 2, 21 and thus prevent the shaft nail 8 from coming out Housing 2, 21 removed and thus the goods connected to the corrugated nail 8 is separated from the goods security device 1.

If the claw-like holding device 7 is moved from a position according to FIG. 1 a by a tool 5, which can enter the interior of the housing 2, 21 along the insertion direction 6 in a manner described in greater detail, by mechanical contact between the tip of the tool 5 and the narrow side of the claw-like holding device 7 is shifted out of its position, the corrugated nail 8 slides out of the slot-shaped opening 13 parallel to the edges 14 and thus the edges 14 are no longer in contact with the grooves 10 of the corrugated nail 8.

For this purpose, the tool 5 can enter the interior of the housing 2, 21 relatively easily and without great effort, by inserting it into an opening 4. It is also conceivable here to provide in the area of the opening 4 a thin-walled wall section, not shown, which must first be pierced by the tool and then opens the opening 4. The opening 4 is arranged in such a way that the narrow side of the claw-like holding device 7 can be reached by a movement of the tool 5 to be carried out on a path to be predetermined, and the claw-like holding device 7 can thereby be shifted from the locked position 7 into the open position 7 ^' . For the sake of simplicity, a linear movement along the insertion direction 6 of the tool 5 is shown in FIGS. 1 a and 2, from which the position of the opening 4 also results. It goes without saying that, in order to improve the security against manipulation of the article security device 1, the movement path of the tool 5 can be more complex, for example following a curved path or also by means of baffles arranged in the interior of the housing 2, 21, for example in the form of one another, not shown here Staggered webs or the like can be difficult. As a result, even with knowledge of the internal structure of the goods security device 1, it is not readily possible to cause the claw-like holding device 7 to be rotated with any tool 5.

The positioning elements 11, which serve to fix the claw-like holding device 7 in the closed position of the claw-like holding device 7, are advantageously sections of the housing 2, 21 which are a little over the E- protrude plane of the support elements 12 in the direction of the claw-like holding device 7 and thus lie in the path of movement of the claw-like holding device 7 when it is moved into the open position of the claw-like holding device 7 ^' according to FIG. 2. By choosing an appropriate plastic, these positioning elements 11 are significantly less stable with respect to the claw-like holding device 7, which is usually made of steel, and are simply sheared off, provided the appropriate dimensioning of the positioning elements 11 and the action of force by the tool 5. This then clears the movement path for the claw-like holding device 7, so that the mandrel 8 is released and can be pulled out of the housing 2, 21. At the same time, the positioning elements 11 are arranged in such a way that, regardless of the exact point at which the tool 5 strikes the claw-like holding device 7, the path of motion of the dome 8 can always be completely released and the dome 8 can thus slide out of the slot 7. A resetting of the claw-like holding device 7 into the closed position shown in FIG. 1a is also prevented by the pressing of the claw-like holding device 7 against the sheared-off positioning elements 11, which bring about a certain clamping of the claw-like holding device 7.

After the claw-like holding device 7 has been moved into the open position, the article security device 1 can no longer be used again. This is achieved in that the projection 16 e.g. is pressed behind the at least partially sheared positioning elements 11 of the housing 2, 21 or other components of the housing, which prevents the claw-like holding device 7 from springing back or pushing back into a position in which the claw-like holding device 7 can come into contact with the corrugated nail 8 again. The goods security device 1 is a goods security device 1 which can only be used once and which, owing to the construction and the low manufacturing costs, can advantageously be attached to the goods already during the manufacture of the goods to be secured and then after removal from the goods can be disposed of.

The claw-like holding device 7 has an offset in the region of the edges 14 of the slot-like opening 13 such that the edges 14 underneath the flat ne of the claw-like holding device 7 protrude downwards. Such an offset 15 in the region of the edges 14 serves to make it easier for the corrugated nail 8 to be inserted into the slot-like opening 13, since the offset 14 causes a certain elasticity of the edges 14 in the insertion direction 26. At the same time, this prevents the shaft nail 8 from being pulled out counter to the insertion direction 26, since the design of the edges 14 causes the shaft nail 8 to be clamped in attempts to pull the shaft nail 8 out of the housing 2, 21.

FIGS. 4 and 5 show an embodiment of an article security device according to the invention in a sectional plan view with locked or released fastening means and deactivation of an article security element by a deactivation element arranged on the linearly displaceable claw-like holding device and the claw-like holding device in enlarged views. The same part numbers as in the above description for FIGS. 1 to 3 denote the same components, so that only the existing differences between the configurations are to be discussed here and reference is otherwise made to the description of FIGS. 1 to 3.

In contrast to the design of the goods security device according to the invention in FIGS. 1 to 3, the claw-like holding device 7, 7 ^' according to FIGS. 4 and 5 is held in linear guide elements 19 which are arranged on the inside of the lower housing part 2 and are shaped accordingly Interact leading edges 20 which are provided on the edges of the claw-like holding device 7, 7 ^' . The guide edges 20 can be formed, for example, by bending edge regions of the claw-like holding device 7, 7 ^' and are therefore simple and inexpensive to provide when producing the claw-like holding device 7, 7 ^' . The claw-like holding device 7, 7 ^' thus performs a slide-like displacement movement in the displacement direction 32 between the closed starting position (7) and the opened end position (7 ^' ) when the tool 5 acts in the insertion direction 6 on a contact section 28 which is also angled as a tab, which means that in basically already described, the edges 14 of the slit-like opening 13 not shown here Release the corrugated nail 8 in its receptacle 18 and thereby detach the goods security device 1 from a product, not shown. The displacement movement of the claw-like holding device 7, 7 ^' is limited on the insertion side of the tool 5 by a stop 33, so that in the closed position of the claw-like holding device 7, 7 ^' the shaft nail 8 always comes to rest securely in the slot-like opening 13 and is held. Due to the linear guidance of the claw-like holding device 7, 7 ^' by means of the linear guide elements 19 and the guide edges 20, a safe movement of the claw-like holding device 7, 7 ^' can always be ensured without the need for costly positioning measures for the claw-like holding device 7, 7 ^' , Tilting of the claw-like holding device 7, 7 ^' can also be reliably avoided.

Furthermore, on the claw-like holding device 7, 7 ^' , as shown by way of example in FIGS. 5a and 5b, chamfers 37 or projections can be provided, which engage in corresponding shapes in the linear guide elements 19 and a type of locking fixing of the claw-like holding device 7, 7 ^' Allow at certain points within the linear guide elements 19. In this way, a pre-positioning of the claw-like holding device 7, 7 ^' in the starting position for inserting the shaft nail 8 as well as an end position after the displacement of the claw-like holding device 7, 7 ^{' can be} determined by arranging corresponding recesses within the linear guide elements 19 into which can intervene in the shifting or projections and lock.

In the area of the passage of the tool 5 in the direction of the claw-like holding device 7, 7 ^'may housing side or on the claw-like holding device 7, ^7' are arranged deflector 31 is provided, which allow a passage of the intended tool 5, improper tools 5 make this passage difficult or even impossible. For this purpose, the deflector elements 31 can be provided with bevels or curves, for example, and the deflector elements 31 can be arranged such that passage is only possible in a very specific position. It is also conceivable to design the contact section 28 and the tool 5 with matching shapes in the form of a mating face, through which manipulation by a tools 5 not provided with such a mating face is further complicated.

The claw-like holding device 7, 7 ^' has an extended deactivation section 29 on the side opposite the insertion side of the tool 5 and here arranged on the contact section 28, which also linearly extends into a region during the linear displacement of the claw-like holding device 7, 7 ^' already described 30 is moved, in which the deactivation section 29 in the end position 1 ^'of the claw-like holding device 7, 1 ^' comes to rest at least in sections over the article security element 27 and can interact with it. If, for example, the article security element 27 is designed as an acustomagnetic AM element, then this AM element 27 must be able to oscillate freely in an externally applied oscillating field, for example a detection gate, for the intended signaling in order to give the required oscillation response. However, if this AM element 27 is completely or partially prevented from vibrating by mechanical contacting with the deactivation section 29, for example by clamping the AM element 27 through the deactivation section 29, the detuning of the oscillatable article security element 27 will result in the entire being detuned Goods security device 1 is permanently deactivated and can be removed without problems from the area of the detection locks without false alarms occurring after the intended deactivation. By providing this deactivation section 29, the goods security device 1 can be reliably deactivated at the same time when the connection between the corrugated nail 8 and the claw-like holding device 7, 7 ^' is released. This deactivation takes place inevitably and without any further action on the part of the sales personnel either by an express deactivation process or automatically when the connection between corrugated nail 8 and claw-like holding device 7, 7 ^{'is released} and can therefore, provided that the deactivation takes place when the article security device 1 is detached from the goods, by Sales personnel are not forgotten at all and trigger the negative consequences already described. This also prevents customers from loosening goods security devices 1 forgotten when paying for the goods through self-tests and thereby damaging the goods in most cases, as a result of which the goods are exchanged or replaced by dealers must become. The claw-like holding device 7, 7 ^' can be reset either by latching mechanisms or the like which are not described in detail in FIGS. 4 or 5, but the clamping between the deactivation section 29 and the article security element 27 in the overlap region 30 may also suffice for this.

FIGS. 6 and 7 show a further embodiment of an article security device 1 according to the invention in a sectional plan view with the fastening means 7, 7 ^' locked or released as a reusable embodiment with a resilient return element 34. Again, reference is made to the description of FIGS. 1 to 3, but also to the description of the configuration according to FIGS. 4 and 5, and essentially only the configuration of reusability is described.

In contrast to the deactivatable embodiment according to FIGS. 4 and 5, in the article security device 1 according to FIGS. 6 and 7, a spring element 34 in the form of a coil spring 34 ensures that after a deflection due to the linear displacement due to the force of the tool 5 the claw-like holding device 7, 7 ^'is returned to the starting position 7, whereupon the corrugated nail 8 can be reinserted into the slot-like opening 13 in the manner already described and can be locked with the edges 14 of the slot-like opening 13.

For this purpose, the spring element 34 designed here as a helical spring is inserted in a housing-side receptacle 35 in such a way that it protrudes in the direction of the contact section 28 of the claw-like holding device 7, 7 ^′ and comes to lie pretensioned against this contact section 28. Lateral bulging of the springs 34 is prevented on the one hand by a projection 36 arranged on the contact section 28, which protrudes into the interior of the helical spring 34 and fixes it accordingly at this end, on the other hand by receiving the spring 34 in a receptacle 35 in the Lower housing part 2. If the claw-like holding device 7, 7 ^' is now moved in the displacement direction 32 by the tool 5 as already described, the helical spring 34 is further tensioned and presses the claw-like holding device 7, 7 ^' back into place after being relieved by the tool 5 their starting position back. As a result of this and by avoiding canting due to the linear guidance of the claw-like holding device 7, 7 ^′ in the guide elements 19, the goods security device 1 can be used repeatedly, as a rule very often, and is therefore correspondingly inexpensive to use.

It goes without saying that the spring element 34 can be realized in very different ways, for example as a spiral spring, torsion spring, elastically deformable material or the like.
