Parking cards

Claim 1

A parking card for displaying a prepaid parking time period, said card being in the form of a strip of tearable material having month, day and hour indicia printed on separate areas thereof, each of said indicia areas being formed with severance lines enabling the user to separate a part of the card in each of said areas along selected severance lines thereof to identify the month, day and the arrival and expiration times of the preselected prepaid parking time period; the severance lines in at least one of said indicia areas each being in the form of a continuous cut defining a tab which may be pressed out of the card, the ends of each continuous cut terminating adjacent to but spaced from the edge of the card or another continuous cut, forming a connecting web portion between the card and the tab; the tabs in at least one of said indicia areas being spaced along at least one edge of the card, each of said tabs having a generally triangular shape extending inwardly from the adjacent edge of the card to an apex and having the earliest and latest permitted arrival times printed adjacent one end of the tab and the expiration time printed adjacent the opposite end of the tab to define the preselected parking time period associated with that tab; and the relative lengths of the continuous cuts and connecting web portions, and the strength of the material providing the web portions, defining the respective tabs being such that the user may press each tab out of the card along said continuous cut, and pull same to cause the card to be torn along said connecting web portion, producing thereby a readily-discernible, irreversible alteration in the card.
