Title: TELEPHONE PAYSTATION COIN RECEPTACLE COVER
Abstract:
A shutter plate for a self-locking cover for a telephone paystation coin receptacle includes a coupler for joining a shutter control arm to the shutter plate that deforms when a force having a predetermined magnitude is applied to the control arm. The deformation of the coupler provides an indicator that an attempt to move the shutter plate to expose an aperture in the self-locking cover has occurred. The coupler may be one or more holes in a portion of the shutter control arm that is external of the self-locking cover. The coupler may take the form of a weld that joins the shutter control arm and the shutter plate. Frangible material may also be used to fill openings in the control arm to provide a tamper indicator. The tamper indicator of the present invention facilitates detection of tamper attempts by visual inspection.
