Definitions
- This invention relates to an anti-theft device for an entertainment system and is particularly but not exclusively concerned with such a device for an in-car entertainment system.
- the cover has an opening on its underside serving as a hand-hold for slidably positioning and removing the .device.
- the face of the cover has a lock for actuating locking elements capable of projecting from the cassette-shaped part so as to engage the player internally and prevent removal of the device.
- the lockable device suffers from the disadvantage that a relatively complex lock is required to accommodate different kinds of cassette player. A similar design is described in GB 2168522.
- an anti-theft device for a playing and/or recording unit using a cassette or other data carrier insertable into a playing position in the unit in which it is retained by latching means, said device comprising a shaped part simulating said data carrier so as to be insertable into said latched position of use in the unit, a cover positionable over the front face of the unit so as to prevent access to at least the eject mechanism of the unit, and means for lockably interconnecting the cover and the shaped part.
- a radio/cassette unit 1 has a box-shaped body indicated in chain-dot line which is normally concealed behind the facia board to leave the front face with its controls (including a cassette eject button not shown) and a cassette opening 2 exposed.
- a shaped part 3 is in the form of a dummy cassette having the usual openings 4 for engaging the cassette drive spindles of the cassette unit.
- Extending rearwardly of the dummy cassette 3 is a metal tongue 5 securely fixed to the cassette 3 and having an upturned free end from which extends a locking bar 6.
- a steel cover 7 has top, bottom and side walls defining a box shape with a front opening conforming to the front face of the radio/cassette unit.
- a lock 8 has a key opening on the rear side wall of the cover and a barrel 9 extending forwardly to a locking lever 10 which is shown in the horizontal unlocked position and again in the vertical locked position in which it engages behind the locking bar 6 when the anti-theft device is in use.
- the dummy cassette 3 is inserted into the cassette opening 2 of the unit 1 until it is latched into position by the latching mechanism leaving the tongue 5 and the locking bar 6 projecting from the unit 1.
- the cover 7 is then presented to the unit 1 so that the front opening thereof overlies the front face of the unit 1.
- the locking bar 10 of the lock 8 is in its horizontal unlocked position forwardly (i.e. nearer to the unit 1 than) the locking bar 6.
- Turning the key in the lock moves the lever 10 into the vertical locking position in which it engages immediately in front of the locking bar 6 so holding the cover 7 tightly on the facia board.
- the cover 7 may be brightly coloured and otherwise marked to draw attention to the security system which, as will be appreciated from the above description, is reliant upon the latching mechanism of the radio/cassette unit to prevent withdrawal of the dummy cassette 3 and indirectly removal of the cover 7, the lock 8 serving merely as part of the locking means for interconnecting the dummy cassette 3 and the cover 7. Because the cover 7 denies access to the eject mechanism the anti-theft device can only be disabled by use of the key to remove the cover 7 followed by operation of the eject mechanism to release the dummy cassette 3. Any attempt to lever the cover 7 away from the unit 1 tends to pull the dummy cassette 3 out of the cassette opening with consequent damage to the latching mechanism thereby rendering the unit unsaleable.
