Definitions

  • the present invention relates to a safer for a prallellepipedic cassette, particularly for such cassettes as are used for CD, DVD, videotapes, data games, MC or the like.
  • a safer is a device which is mounted on the cassette and is locked to the cassette so that it can be removed therefrom only by an authorized person. Safers are used in shops and department stores in order to prevent that the cassette with the object contained therein is removed from the shop or department store without being paid for, and for this purpose the safer is provided with an element which triggs an alarm if the safer is moved from the shop or a defined area in the department store.
  • the invention relates to a safer of the kind comprising a container with two flat sides and four mutually perpendicular narrow sides for enclosing the cassette at the flat sides and three of the narrow sides, the fourth narrow side defining an access opening through which the cassette can be inserted into and removed from the container; a detent member mounted on one of said three narrow sides, which joins said open fourth side, for movement between an operative position and an inoperative position the detent member blocking the passage through the access opening in said operative position and allowing the passage through the access opening in said inoperative position; and a latch member biased to an engaged position to lock the detent member in the operative position thereof, the latch member being adapted to be disengaged by an external mechanism to release the detent member for movement to the inoperative position.
  • US 5,147,034 discloses a safer of the type defined above wherein the detent member comprises a rail and a stop element connected by a hinge to one end of the rail for pivotal movement about a transverse axis.
  • the rail with the stop element is located inside the container adjacent one of the enclosing narrow sides, which extends transversely of the access opening and joins said opening.
  • the detent member can be moved axially parallel to the plane of said one narrow side between the operative and inoperative positions.
  • the stop element blocks the passage through the access opening but when the detent member is unlatched and is moved to the inoperative position the stop element can pivot to a position in which it allows free passage through the access opening.
  • EP 0 508 201 A2 (Pataco AG) and WO 00/75469 A1 (MW Trading (UK) Ltd) describe safers wherein the detent member comprises a rail which is located inside the container for displacement adjacent one of the enclosing narrow sides between the operative and inoperative positions as described in US 5,147,034.
  • the stop element is integral with the rail and in the inoperative position can be resiliently bent so as to allow free passage through the access opening.
  • US 5,882,052 (Whitehead) describes safers wherein the detent member is mounted to the outside of the container for movement between the operative and inoperative positions along a narrow side which extends transversely of the access opening and joins said opening.
  • the detent member is guided for imparting to said member also a movement transversely of said narrow side when moving between the operative and inoperative positions
  • Another problem is that although the existing safers of the kind referred to herein can be easily handled by the attendants at a counter where the safer is to be removed from the product the handling of the safer is felt as an inconvenience.
  • the object of the Invention Is to provide a safer of the kind referred to herein which overcomes the problems accounted for and to provide at the same time a simple safer construction which is well suited for mass production at low costs.
  • the safer disclosed in FIGS 1 to 3 comprises in a known manner a container 10 which can be injection molded of a transparent plastics material and comprises two flat sides and four narrow sides, viz. a closed side wall 11, an opposite open side 12, three edge walls 13, 14 and 15 and an access opening 16.
  • the container is dimensioned to receive therein a CD cassette which is inserted into the container through the access opening and is confined in the container by side wall 11 at one side of the cassette and by a corner flange 17, a rim 18 extending along wall 15, and a rail 19 extending between walls 13 and 15 and defining together with side wall 11 access opening 16.
  • An opening 20 is provided in side wall 11 for productional reasons.
  • An element (not shown) attached to the inside surface of side wall 11 can be adapted to trig an alarm system if the safer is removed from a display or shop as is the customary purpose of the safer.
  • the container can be adapted to receive therein other products such as cassettes or packages for DVD, video tapes, data games or other attractive and expensive products that are exposed in a shop or department store.
  • a detent mechanism 21 is located on top of the container on the upper surface of wall 15 adjacent access opening 16. It comprises a housing 22 integral with the container, which forms a slot like space 23 open at the rear side of wall 11.
  • a hook shaped detent member 24 Is mounted at one end thereof to the housing by means of a pin 25 extending transversely of wall 15, for pivoting between the position shown in FIGS 4 and 5 in which the detent member projects obliquely from housing 22, and that shown in FIG 6 in which the detent member is received in space 23.
  • the detent member has at the other end a stop member 26 which is formed by an end flange on the detent member, projecting downwards therefrom.
  • the stop member In the position of the detent member shown in FIG 5 the stop member partly covers access opening 16 at the upper end thereof and thus blocks the passage through the access opening. This is an operative position of the detent member while the position of the detent member shown in FIGS 4 and 5 is an inoperative position thereof.
  • the detent member is biased towards the inoperative position by a spring 27.
  • a latch mechanism for locking the detent member in the operative position comprises a spring blade 28 which is mounted in a space 29 formed by housing 22, by means of a pin 30 integral with the housing.
  • the spring blade is biased downwards by the Inherent resiliency thereof to extend at the free end of the spring blade into space 23 through an opening 31 between spaces 23 and 29.
  • Space 29 is covered by a cover plate 32 which is securely connected with housing 22 as by ultra sound welding. The cover plate abuts pin 30 in order to securely hold the spring blade on that pin.
  • Detent member 24 forms a recess 33 in the upper surface thereof, which is dimensioned and shaped to receive the free end portion of spring blade 28 therein when the detent member Is in the operative position.
  • the detent member When the detent member is being swung clockwise from the inoperative position shown in FIGS 4 and 5 towards the operative position shown in FIG 6, it cams the spring blade upwards against the Inherent resiliency thereof and then, when the operative position is reached the spring blade snaps into the recess. The detent member is now locked in the operative position by the spring blade. If a dishonest person tries to swing the detent member back to the inoperative position this will be strongly resisted by the spring blade since pressure will be exerted against an edge of the spring blade and the spring blade offers a very great resistance against bending in this direction.
  • the detent mechanism 21 When the detent mechanism 21 is in the inoperative position as shown in FIGS. 4 and 5 the passage through access opening 16 is free and a cassette 37 can be inserted into container 10 through the access opening as shown in FIG 2. Then the detent member 24 is swung manually to the operative position, shown in FIGS 3 and 6 in which stop member 26 of detent member 24 blocks the access opening, so that the cassette cannot be withdrawn from the container.
  • the cassette is exposed to the customers in the department store or shop with the cassette enclosed in the safer which trigs an alarm system if the cassette together with the safer is removed from the department store or shop.
  • the cassette is removed from the safer by an attendant in the department store or shop and this is done by means of an external opener 38 shown in FIG 7.
  • the opener comprises two side walls 39 and 40 at right angle to each other, and a bottom 41.
  • the opener is dimensioned such that the safer with the detent mechanism can be positioned in the opener with side wall 11 resting on bottom 41 and with the top side of housing 22 applied against side wall 39.
  • a strong permanent magnet 42 is mounted in side wall 39, and with the safer positioned in the opener as described this magnet attracts spring blade so that it will be bent out of recess 33 allowing the detent member to swing to the inoperative position under the bias of spring 27 when the safer is lifted from the bottom 41 of the opener. Then, cassette 37 can be removed from the safer.
  • spring blade 43 The security provided by means of spring blade 43 can also be achieved by the arrangement disclosed in FIG 13.
  • a spring blade 45 is connected with housing 22 at one end of the spring blade extending in the transverse direction of side wall 11 and forming a hook 46 at the other end. In the operative position of the detent member the hook engages a notch 47 in the detent member to hold this in the operative position.
  • the opener in this case in addition to magnet 42 in side wall 39 has a magnet 48 in side wall 40 no magnet being provided in bottom 41.
  • spring blades 28 and 45 will be actuated by their respective magnets 42 and 48 simultaneously in order to release the detent member for movement to the inoperative position.
  • the detent member forms a chamfered end surface 49n order to engage hook 46 at this surface and bend spring blade 45 at movement of the detent member to the operative position before the hook can snap into notch 47.
  • the latch mechanism including spring blade 28 can be provided alone as can also the latch mechanism including spring blade 45 but for increased safety spring blade 28 should be provided in combination with either spring blade 43 or spring blade 45.
  • the detent member 24' is mounted on the container for linear displacement in the transverse direction of side wall 11 between the inoperative position disclosed in FIG 16 and the operative position disclosed in FIG 3.
  • the detent member can be mounted on pins which are guided for linear movement in housing 22, or the detent member can be displaced on pins which are fixedly mounted in the housing.
  • the detent mechanism can be the same as that disclosed in FIGS 5 and 6.
  • the detent member can be spring biased towards the inoperative position e.g. by means of helical pressure springs passed onto the pins.
  • FIGS 17 to 19 disclose a third embodiment of the safer of the Invention.
  • Stop member 26 of the detent mechanism is mounted to or made integral with a cylindrical shaft 50 which is mounted for axial displacement and rotation in housing 22.
  • shaft 50 projects from the housing and stop member is in a rotated position in which it leaves access opening 16 unblocked so that a cassette can be inserted into or withdrawn from the container through the access opening. In other words, this is the Inoperative position of the detent mechanism.
  • Shaft 50 is biased by a helical pressure spring 51 towards this position.
