VHS videocassette security device

Abstract

A tamper resistant device designed to be fitted into the blind hole of a standard VHS videocassette tape in such a manner as to prevent use/loading of the cassette. The device consists of a cylindrical body, pawl, cross pin, spring and a key for removal of the device. This device provides much more security than the current state of the art. Contents of the videocassette can neither be damaged by recording over existing program(s) nor can they be viewed, as insertion of the cassette into a player/recorder is prevented by the device. Furthermore, the device is designed to be compatible with all existing sleeves or covers used for storage. The device can be easily engaged without use of the key. Also, the device cannot be removed until the pawl neutral position is maintained while the device is being removed. Both the pawl and key hole design serve as tamper resistant components. Until the pawl's neutral postion is achieved, either of two locking surfaces engage an under cut built into the videocassette. As the pawl is spring loaded upward attempts at tampering will be hampered as any lifting of a tampering implement will cause the pawl to return to its locked position. Pushing the pawl downward, beyond its preset limit for release engages the double lock surface of the pawl. The key hole large diameter allows for sturdy key construction while the smaller diameter is designed to prevent tampering with the use of ordinary household items. It is the intent of this invention to provide an efficient and low cost means of providing security from loss or unauthorized viewing of videocassette tape contents.
