Definitions

  • This invention relates to a lockable cassette, henceforth called lock-cassette, intended for video cassette apparatus for blocking the cassette receiving opening thus physically preventing the video cassette apparatus from beieng used.
  • the lock-cassette is furthermore equipped with a built-in electronic alarm which will sound an alarm signal if someone, for instance a burglar attempts to move the vide apparatus with lock-cassette.
  • the lockable video cassette furthermore has a built- in battery-operated alarm system which will greatly reduce the number of thefts of expensive video machines.
  • the present invention also provides a lockable video cassette system which can be used in connection with all known types of video cassette machines.
  • cassette lock mechanism in no way can cause any damage to the video cassette apparatus as no metal components or particularly hard components will come in contact with the internal components of the video cassette apparatus when the lock- cassette is inserted and locked in place.
  • Fig.1 shows a lock-cassette in perspective.
  • Fig.2 shows a cross-section of a lock-cassette.
  • Fig.3 shows a cross-section through fig.2 in the direction 7-7.
  • Fig.4 shows the same cross-section as in fig.3, but with a locked cassette.
  • Fig.5 shows a side-view of a video apparatus with top loading.
  • Fig.6 shows a side view and part cross section of a video apparatus with front-loading.
  • the lock-cassette shown in fig. 1 - 5 is generally designated with the numeral 8.
  • the cassette comprises an upper and a lower box-half 9, 10 which might have identical shapes.
  • the cassette dimensions, width 11, length 12, thickness 13 are substansially the same as those of a conventional video cassette.
  • the lock-cassette has a shape which is adapted to fit the video apparatus internal mechanisms and components.
  • Mounted within the cassette is a cylindrical lock 14 operated by key 15.
  • a rotary camshaft device 16 having a mainly oval cross section 17 is mounted inside the cassette.
  • the camshaft is turned by means of the arm 18 which connects the cylindrical lock 14 to the camshaft 16.
  • On each side of the camshaft 16 and resting against said camshaft there are mounted two lock bolt devices 19.
  • the ends of the bolts 19 are provided with end pieces 20 made from a soft plastic or rubber material.
  • the cassette 8 has openings 31 at both ends for the bolts 19.
  • the inside wall of the cassette receiving opening of the video apparatus is indicated by the line 21.
  • the lock-cassette 8 has end stops 22 on the outside.
  • the end stops 22 have notches 23 thereby making it possible to remove the stops if required.
  • the lock-cassette has been designed to fit two types of video machines. When used in a top loading machine as shown in fig.5 the end stops 22 are removed and the cassette is then pushed all the way in up against the end stop 24 in the cassette receiving opening.
  • Fig. 6 shows a cassette being inserted into a side loading machine. It is stopped by end stop 22 placed at a distance 25 from the end of the cassette. The distance 25 equals the distance from the front of the video apparatus to the cassette loading mechanism 26 which automatically will pull an ordinary video cassette into the video player.
  • the lock-cassette alarm system is made up from basically known components mounted inside the cassette and include switch 27, alarm device 28, battery 29, circuit card 30 and other necessary electronic components.
  • the alarm system components have been assembled by applying known assembly methods. Turning the key 15 will rotate the cylindrical lock 14 approximately 180 degrees and arm 18 will thereby rotate camshaft 16 approximately 90 degrees. Camshaft 16 which rests against lock bolts 19 will push the lock bolts outwards thereby pressing end pieces 20 against the inner wall 21 of the cassette receiving opening.
  • the relatively soft end piece 21 will be partly compressed and will furthermore to some degree be squeezed into holes and cavities in inner wall 21. The compression forces and the friction forces betwe ⁇ n end pieces 20 and inner walls 21 will effectively, but gently lock and secure the cassette in the cassette receiving opening as has been shown in experiments.
  • the arm 18 will simultaneously turn camshaft 16 and activate alarm system switch 27. Any movement of the video apparatus with the lock cassette 8, as for instance if someone attempts to move the video apparatus, will close a movement sensitive switch in the system and thereby activate the alarm system and turn on the audible alarm.

Abstract

Cassette vidéo verrouillable (8) conçue pour bloquer de manière verrouillable et fixer des appareils à cassette vidéo. A l'intérieur de la cassette se trouve un verrou cylindrique (14) qui est relié via un bras (18) à un arbre à came (16) poussant des pênes (19) dotés de pièces terminales (20) à base de matériau de caoutchouc ou de plastique souple vers l'extérieur contre les parois intérieures (21) de l'ouverture recevant la cassette et, grâce à des forces de compression et de friction, verrouillant et fixant la cassette.
