Definitions

  • the invention relates to an opener for a magnetic latch in an anti-theft device for a cassette, comprising a frame or box for enclosing the cassette and having a blocking element which by means of the magnetic latch is locked in a position preventing withdrawal of the cassette from the frame or box, a magnet for opening the magnetic latch by engaging the anti-theft device with the magnet being provided in the opener.
  • Anti-theft devices of the kind referred to above having a magnetic latch protruding from the frame or box have been used for a long time in order to protect for example CD cassettes and video cassettes against theft in shops and department stores, and such anti-theft devices are disclosed for example in EP-B1 0 451 189, EP Bl-0 581 811, and EP-B1-0 620 888.
  • the anti-theft device can be removed in a rational manner from the protected product when this is handed out from the counter of the shop or department store openers which are attached to the counter and have a recess with a magnet on the bottom thereof the magnetic latch being introduced into the recess when the anti-theft device is to be removed, in order that the magnet shall act upon the magnetic latch and bring it to the open position so that the cassette and the anti-theft device can be separated.
  • These magnetic latches are mounted inside an edge surface of the frame or box and are disclosed for example in EP-A2- 0 508 201 and EP-B1-0 712 460.
  • In order to open the magnetic latch it is necessary to engage said edge surface with a magnet in register with the site of the latch, and this cannot be effected by using existing openers for magnetic latches of the protruding type. It is thus necessary to have a further opener in order to remove anti- theft devices with the magnetic latch inside an edge surface of the frame or box, which no doubts makes the use of the anti-theft devices more complicated.
  • the purpose of the invention is to satisfy this demand, which is achieved by providing an opener of the kind referred to, which according to the invention is constructed for operating optionally a magnetic latch which protrudes from the anti -theft device, and a magnetic latch which is located inside an edge surface of the anti-theft device, and comprises a body having a raised portion with a flat upper surface which at a shoulder connects with a lowered portion with a flat upper surface extending along the shoulder the raised portion having a recess with a magnet on the bottom thereof to receive therein the protruding magnetic latch for engagement with the magnet, and the lowered portion having in the flat upper surface one or more magnets mounted flush therein for engagement of said edge surface with the magnet or magnets, respectively, with the anti-theft device abutting the shoulder.
  • FIG. 1 is a perspective view of the opener ready for use
  • FIG. 2 is a perspective view of the opener in a blocked condition
  • FIG. 3 is a perspective view of the opener and illustrates conversion of the opener between the condition in which it is ready for use, and the blocked condition
  • FIG. 4 is a perspective view illustrating the use of the opener when an anti -theft device having a protruding magnetic latch shall be opened
  • FIG. 5 is a corresponding perspective view illustrating the use of the opener when an anti-theft device having the magnetic latch inside an edge surface thereof shall be opened.
  • the opener disclosed in the drawings comprises a rigid body 10 of a suitable plastic material, which can be attached to a counter or the like by means of screws.
  • the block forms on the upper side a raised flat surface 11 and a lowered flat surface 12 a vertical shoulder 13 being provided between the two surfaces.
  • a metal frame 14 confines a recess 15 a permanent magnet 16 being provided on the bottom of the recess .
  • Two permanent magnets 17 and 18 are mounted flush with the flat surface 12 mutually spaced in the longitudinal direction of said surface.
  • the body 10 forms an abutment 19 projecting from the surface 12.
  • a recess 20 is provided in which a block 21 matching the recess is located having the upper surface thereof flush with the surface 11.
  • the block is locked in the recess 20 by means of a key lock 22.
  • a recess 23 is provided in the surface 12 a matching block being located in said latter recess.
  • This block is locked by means of a key lock 25 in the recess 23 and has the upper side thereof flush with the surface 12.
  • An anti-theft device 26, FIG. 4, for example such a device as is disclosed in EP-B1-0 451 189, EP-B1-0 581 811, and EP-B1-0 620 888, comprises a frame 27 for receiving therein a cassette for a CD or a video tape.
  • a magnetic latch 28 protrudes from the frame preventing directly or indirectly removal of the anti-theft device from the cassette.
  • the magnet 16 in the recess is mounted in an inclined position, but for other magnetic latches the magnet can be mounted in a horizontal position.
  • the magnet can be depressed against a bias when the magnetic latch is engaged with the magnet .
  • the bias can be provided by a spring but in the preferred embodiment it is provided by magnetic force the magnet 16 being attracted to the metal frame 14 but is kept spaced therefrom by means of spacers in the recess 15.
  • an anti-theft device 29, FIG. 5 is concerned for example according to EP-A2-0 508 201 and EP-B1 0 712 460, which comprises a frame 30 and has the magnetic latch provided inside an edge surface 31 of the frame, the part of the opener which has its site in the surface 12 will be used.
  • the magnetic latch can comprise a metal tongue or two such tongues mutually spaced in the longitudinal direction of said edge surface, which can be acted upon magnetically.
  • the magnets 17 and 18 are located such that when said edge surface of the anti-theft device is displaced on the surface 12 in the direction of the arrow B and the anti -theft device is engaged with the shoulder 13 and the abutment 19, the tongue - if only one is provided - will be in register with one of the magnets
  • the magnetic latch is brought to the opened position for removal of the anti-theft device from the cassette.
  • the latch comprises a spring biased slide which can be displaced in the frame along said edge surface, the slide being kept in the blocking position by a latch tongue attached to the frame and engaging a shoulder on the slide.
  • the opener described facilitates handling of anti- theft devices with a magnetic latch of one type or the other.
  • the blocks 21 and 24 are provided in order to make it possible to block the opener.
  • the lock 22 in the block 21 can be opened so that the block can be lifted from the recess 20 as shown in FIG. 3 in order to be located as a cover over the recess 15 and be locked in this position as shown in FIG. 2.
  • the lock 25 in the block 24 can be opened and the block be moved from the recess 23 to a recess 33 in the surface 12 in which it is locked by means of the lock 25 in a position in which the block protrudes from the surface 12 as is shown also in FIG. 2. Locking and

Abstract

L'invention concerne un dispositif d'ouverture destiné au verrou magnétique du dispositif antivol d'une cassette et comprenant un cadre ou une boîte destiné à loger une cassette et doté d'un élément de blocage qui est verrouillé par un verrou magnétique dans une position empêchant que la cassette puisse être retirée du cadre ou de la boîte. Un aimant (16; 17; 18) permettant d'ouvrir le verrou magnétique par mise en contact du dispositif antivol et de l'aimant contenu dans le dispositif d'ouverture. Le dispositif d'ouverture est conçu pour faire fonctionner optionnellement un verrou magnétique (28) en saillie sur le dispositif antivol ou un verrou magnétique placé à l'intérieur d'une tranche (31) du dispositif antivol. A cet effet, le dispositif d'ouverture comprend un corps (10) ayant une partie en relief avec une surface supérieure plate (11) qui est reliée, au niveau d'un épaulement (13), à une partie inférieure ayant une surface supérieure plate (12) s'étendant le long de l'épaulement. La partie en relief a un creux (15) dont le fond est doté d'un aimant (16) afin de recevoir le verrou magnétique destiné à être appliqué sur l'aimant. Dans la tranche supérieure plate, la partie inférieure a au moins un aimant (17, 18) affleurant pour que ladite tranche (31) dotée de l'aimant ou des aimants soit respectivement en contact avec le dispositif antivol adjacent à l'épaulement.
