Filed:

Apr 12, 1999

Appl. No.:

09/290525

Inventors:

David E. Grudzinski - Friendswood TX 77546

Assignee:

David E. Grudzinski - Houston TX

International Classification:

H04M 100

US Classification:

379145, 379453, 294 15, 294 16, 294 34

Abstract:

A guard for preventing the vandalism of the vault and vault door of a pay telephone, comprising a plurality of rigid segments. Each rigid segment includes an attachment end and a free end, defining a perpendicular distance therebetween. Each of the rigid segments is attached at its attachment end to the lower housing of the pay telephone immediately adjacent and substantially surrounding the vault door. In the preferred embodiment, the plurality of rigid segments comprise one integral rigid member. The guard changes the leverage point of the pry bar of a vandal so as to prohibit such vandal from forceably removing the vault door. The leverage point is changed from proximate the vault door to the free end of a rigid segment or integral rigid member.

International Classification:

H04M 17/00

US Classification:

379143000

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.

Inventors:

William W. White - Houston TX
David E. Grudzinski - Friendswood TX

International Classification:

H04M 100

US Classification:

379451

Abstract:

This invention is a guard for preventing the vandalism of the keypad of a telephone. If the telephone is a pay telephone, the invention further prevents, thus preventing entry into the telephone money box from the upper housing area. The telephone guard, composed of an upper housing guard and a keypad guard, is secured by high strength visible fasteners to the upper housing of a pay telephone. The upper housing guard and keypad guard are mated tightly to prevent vandals from prying off the keypad guard. The thickness of the keypad guard is greater than the throw length of the push buttons of the keypad. Thus, the force of a blow to the keypad will be absorbed by the front of the guard rather than the push buttons.
