Definitions

  • the invention relates to an anti-theft device for a parallelepipedic box for CD, DVD, MC video tapes, data games, or the like, comprising a frame of plastic material, which has two flat sides and four mutually perpendicular narrow sides to enclose the box at the flat sides and three of the narrow sides while the fourth narrow side is open for insertion of the box into the frame and withdrawal of the box therefrom, a slide of plastic material for retaining the box in the frame, which is located inside the frame and is plane-parallel with the narrow sides perpendicular to the open narrow side, and is guided for displacement on and along one of said narrow sides between an inserted lock position and a retracted release position, the slide forming a hook-shaped end portion directed towards the interior of the frame, which blocks the open narrow side in the lock position of the slide, while this narrow side is uncovered in the release position of the slide, and a latch device for locking the slide to the frame in the lock position of the slide.
  • O-A1-98/36143 discloses and describes an anti- theft device of the kind referred to wherein the latch device comprises an obliquely protruding spring tongue of a magnetically attractable metal, which is attached to the frame at one end thereof and is directed from the open narrow side to engage at the other end thereof a shoulder on the slide on the lower side thereof when the slide is in lock position.
  • the spring tongue is attracted to a magnet which is moved towards the frame from the outside so that the spring tongue is disengaged from the shoulder on the slide.
  • the object of the invention is to further reduce the already low manufacturing cost for an anti -theft device of the kind referred to above while maintaining high demands on the security against unauthorized removal of the anti- theft device from the protected product. It has been real- ized that this cannot be done without robotizing the manufacture, which implies that the details of the anti -theft device are as few as possible and easily can be mounted together. This requirement is not fulfilled by a latch device as that disclosed in US-A-5 147 034 because the latch de- vice comprises a pin and a spring which must be put together, nor by such a latch device as that disclosed in O- Al- 98/36143 because the spring tongue is attached to the frame .
  • the inven- tion provides an anti -theft device of the kind referred to above having the characteristics of claim 1.
  • the latch device i.e. the tongue which shall engage the lower side of the slide, is mounted in a very simple manner, viz. by the plate forming the tongue being placed loosely in the depression in the frame, which is a simple mounting step well suited for being performed by a robot .
  • FIG. 1 is a side view of the anti-theft device as seen from one flat side thereof
  • FIG. 2 is a side view of the anti-theft device as seen from the opposite flat side
  • FIG. 3 is an end view of the anti-theft device as seen from the open narrow side
  • FIG. 4 is an end view of the anti -theft device as seen from the opposite, closed narrow side, i.e. from the left in FIG. 2,
  • FIG. 5 is a cross-sectional view along line A-A in
  • FIG. 2 is a diagrammatic representation of FIG. 1
  • FIG. 6 is an enlarged fragmentary cross-sectional view along line B-B in FIG. 5,
  • FIG. 7 is an enlarged fragmentary cross-sectional view along line C-C in FIG. 1,
  • FIG. 8 is an enlarged fragmentary cross-sectional view along line D-D in FIG. 1
  • FIG. 9 is an enlarged plan view of a plate forming a spring tongue
  • FIG. 10 is a central longitudinal cross-sectional view of the plate in FIG. 9, and
  • FIG. 11 is a fragmentary longitudinal cross-sectional view of the slide and the frame at the left end of the slide in FIG. 6 .
  • the anti-theft device disclosed in the drawing is intended for a parallelepipedic box or cassette enclosing a CD but the anti-theft device principally can be constructed in the same manner in order to be mounted on a box or cassette for DVD, MC, video-tape, data games, or the like.
  • It comprises a flat rectangular frame which is injection moulded of a preferably glass-clear plastic, e.g. polycarbonate, but can also be made of another strong and for the purpose well -suited plastic.
  • the frame has three closed narrow sides 11, 12 and 13, and two flat sides, one flat side thereof, FIG. 1, comprising a wall 14 forming an opening 15, and the other flat side, FIG.
  • the anti-theft device in a conventional manner shall be provided with an element which at movement through an electrostatic or electromagnetic field causes a disturbance of this field in order to trig an alarm.
  • This element preferably is located on the inside surface of the wall 14.
  • two guide ribs 22 and 23 are provided which extend in parallel with the narrow side 11 and project some distance above the upper side thereof.
  • a flat slide 29 of plastic preferably the same plastic as that the frame 10 is made of, or some other plastic having properties which are particularly well suited for the slide, has a uniform width of such size that the slide fits between the wall 14 at one side and the corner portion 16 and the rail 18 at the other side and is located against the upper surface of the narrow side 11 below the guide ribs 22, 23, 25, 26 and 27.
  • the slide is dis- placeable in the longitudinal direction thereof between a lock position which is disclosed by solid lines in FIG. 6, and a release position which is disclosed by dotted lines in FIG. 6.
  • the slide has at the right end thereof as seen in FIG. 6 a flange 30 which projects at right angle from the slide on the upper side thereof as well as the lower side thereof, and in the lock position of the slide the downwardly directed part of the flange engages the end edge of the narrow side 11 and the upwardly directed part of the flange blocks the passage through the open narrow side 19.
  • the flange 30 In the release position of the slide the flange 30 is spaced from the open narrow side 19 as indicated by dotted lines.
  • the slide forms an upwardly directed flange 31 which forms a right angle with the slide and is received in a recess 32 in the narrow side 12 when the slide is in the lock position.
  • a plate 34 of spring steel has a centrally punched tongue 35 which is directed obliquely upwards from the plate such that the plate has U- shape with a web from which the tongue extends, and two limbs one at each side of the tongue.
  • the shape of the plate is in agreement with the shape of the depressions 33, and in each of these depressions such a plate is loosely placed with the tongue 35 directed from the open narrow side 19.
  • the portion of the narrow side 11 which is located under the tongue and between the limbs of the depression 33, raises successively from the bottom surface of the depression to the upper surface of the narrow side 11 from the right to the left as seen in FIG. 6.
  • each tongue 35 is mutually spaced by a web 38 which ends at a distance from the lower side of the slide so that there is between the web and the narrow side 11 a gap 39 the size of which corresponds to the thickness of the plate 34 or is insignificantly larger than said thickness.
  • the tongue 35 of each of the plates loosely placed in the depressions 33 has the end thereof in the recess 36 and engages the web 38 when the slide is in the lock position, the tongues as a consequence thereof prevent displacement of the slide to the right as seen in FIG. 6 to the release position.
  • the plate shall be of a spring steel which can be attracted magnetically, and by a magnet - permanent magnet or electro magnet - being moved towards the lower surface of the narrow side 11 of the frame in register with each of the tongues 35, the tongues will be attracted by the magnets and will be bent towards the sloping portion of the upper surface of the narrow side 11, which is located between the limbs of the depression 33, so that the tongue will be disengaged from the web 38 and the slide will be free for displacement to the right.
  • the spring tongue can pass through the gap 39 in order to engage the left end wall of the recess 37, which takes place in the release position of the slide. As a conse- quence thereof complete withdrawal of the slide from the frame is prevented. It can be withdrawn only to the release position.
  • the tongues 35 can engage the web 38 so firmly that it can be necessary to push the slide slightly inwards in order that the tongues can disengage the web under the influence of the magnetic attraction force.
  • the recess 32 must have such a depth that it allows - with the slide in the lock position - a slight movement to the left. This movement can take place against the action of a compression spring which biases the slide to the right in FIG. 6, but it is better to arrange the flange 31 at a somewhat obtuse angle to the slide as shown in FIG. 11 in order that it will take the perpendicular position under elastic bending at displacement of the slide to the left from the lock position.
  • the flange 31 then fills the same function as a compression spring. It is a substantial advantage in connection with robotizing of the manufacture that it is not necessary to mount a separate compression spring.
  • the pro- jecting portion of the slide 29 is bent downwards slightly when the slide is in the release position, i.e. when the slide is withdrawn partly from the frame (the dotted position in FIG. 6) so that the flange 30 does not block the open narrow side 19; the box or cassette can be pushed through this narrow side straightly into the frame in order to engage the flange 31 the slide then being carried on during displacement to the left to the lock position, which is disclosed by solid lines in FIG. 6 and wherein tongues 35 are in the latching position to prevent the slide from being moved to the release position.
  • the box or cassette is located with the slide in the release position is located in the position shown by dotted lines according to FIG. 5, posi- tioned obliquely about 20° between the wall 14 and the rail 18, the box or cassette then being turned into the frame and thereafter being displaced to the left against the flange 31 and at continued displacement to the left carries on the slide to the locking position.
  • the box or cas- sette after unlocking shall be removed from the frame it is displaced to the right carrying on the slide 29, and when the slide is located in the release position the box or cassette is turned out of the frame to the oblique position shown by dotted lines in FIG. 5 and is then withdrawn obliquely from the frame.
  • the distance between the wall 14 and the rail 18 in the longitudinal direction of the narrow side 11 must of course be made so large that it allows the box or the cassette to be angled in the manner described.
  • This flange is provided in order to prevent a less scrupulous person from inserting a blade-shaped object between the slide 29 and the narrow side 11 where it is uncovered due to the fact that the wall 14 for manufacturing reasons ends at a distance from the right end of the narrow side 11, in order to attempt to press purely mechanically the right tongue from engagement with the web 37 and unauthorized re- move the anti -theft device from the product to be protected against theft.
  • the flange 24 is provided for the same reason. In order to secure the slide in the lock position it is sufficient to have one spring tongue, but the risk of unauthorized removal of the anti -theft device by manipulat- ing the spring tongues is further reduced by two or more spring tongues being provided in line and/or side by side.
  • the anti-theft device is wider than the box or cassette which is located in the anti-theft device, and it follows that the anti-theft device cannot be located in the display racks which are dimensioned for exposing boxes or cassettes which are not provided with this type of anti- theft device.
  • the frame in the em- bodiment shown is provided with legs 41 on the lower surface of the narrow side 11. These legs are so located and dimensioned that they fit in the conventional display racks .
