  • Publication number: 20060177047
    Abstract: The invention is a guard for preventing the vandalism of a pay telephone keypad. Additionally, the invention prevents access to a pay telephone coin vault through the keypad. The inventive guard includes a plurality of attachment points. The attachment points have a shoulder raised above the exterior surface of the inventive guard. When a fastener is inserted through the attachment point, the head of the fastener will be flush or inset with respect to the top surface of the shoulder, thereby preventing leveraging against the fastener head. Additionally, a de minimus gap formed between the perimeter of the fastener head and the inner wall of the shoulder prevents insertion of a prying instrument.

  • Publication number: 20060177031
    Abstract: The invention is a guard for preventing the vandalism of the vault and vault door of a pay telephone. The inventive guard includes a plurality of attachment points and an extended perimeter member. The attachment points have a shoulder raised above the exterior surface of the inventive guard. When a fastener is inserted through the attachment point, the head of the fastener will be flush or inset with respect to the top surface of the shoulder, thereby preventing leveraging against the fastener head. Additionally, a de minimus gap formed between the perimeter of the fastener head and the inner wall of the shoulder prevents insertion of a prying instrument. A perimeter member circumscribes the access opening for the vault door. The perimeter member outwardly extends, changing the leverage point of a prying instrument such that a vandal is prevented from obtaining the leverage necessary to forcibly remove the vault door.
