Description

TECHNICAL FIELD

The present invention relates to portable devices used to scrape films from a substrate and more particularly to a key chain fob that includes a retractable scraper member having a scraping edge adapted to scrape the protective film cover from scratch off lottery tickets and the like.

BACKGROUND ART

Many people enjoy playing the scratch off type lottery tickets. The tickets typically have game indicia such as numbers located beneath an opaque film covering. The player is required to scrape the film covering from the ticket to reveal whether the ticket is a winner or not. The film covering is designed to be tamper proof and, therefore, must be removed with a scraping tool such as the edge of a coin. Although a coin can be used, scraping with a coin is inefficient because the circular edge of the coin can only be used to scrape the film from a small area of the ticket with each scraping movement. Numerous scraping movements are required to remove sufficient film from the ticket to determine if the ticket is a winner. When only a one or two tickets are purchased at a time, a coin is an adequate scraping device. However it would be a benefit for multiple ticket purchasers to have a portable scraping device that could be used to remove the entire film covering from the ticket with only one or two scraping movements.

Although it is desirable to have a large scraping edge for use with some types of scratch off lottery tickets, other types of lottery tickets require the player to scrape only a few of a number of designated small areas when playing the game. It would be a further benefit, therefore, if the portable scraper device had at least two distinct scraping edges with one adapted for scraping only a small area of film at a time. It would also be desirable if the scraper device were easily carried in a pocket or purse and was carried for an additional reason in addition to scraping the film from lottery tickets.

GENERAL SUMMARY DISCUSSION OF INVENTION

It is thus an object of the invention to provide a combined key fob and ticket scraper that has a scraping edge adapted to scrape the entire film area from a scratch off type lottery ticket with one or two scraping movements.

It is a further object of the invention to provide a combined key fob and ticket scraper that has a scraper member that has at least two distinct scraping edges with one adapted for scraping only a small area of film at a time.

It is a still further object of the invention to provide a combined key fob and ticket scraper that has a retractable scraper member.

Accordingly, a combined key fob and scraper device is provided. Combined key fob scraper device includes a scraper blade member having a scraper width, a scraper length, a first beveled scraping edge formed along a first entire width side edge thereof, a second beveled scraping edge formed along a central section of a second width side edge having a length of less than one half the first width, and at least one retraction button engagement aperture formed therein; a blade member housing having a blade member receiving cavity formed therein of a size sufficient to receive therein the entire scraper blade member and that is accessible through a blade member positioning port that sized to allow the scraper blade member to pass width wise therethrough, a key ring receiving aperture formed through an end section thereof, and a retraction channel, having a first and second channel end, formed through an outer surface of the blade member housing and into connection with the blade member receiving cavity, having a first plurality of ratchet teeth running along a first retraction channel sidewall; and a retraction button having a ridged bottom surface adapted to engage the ratchet teeth and a blade member engagement protrusion adapted to engage the at least one retraction button engagement aperture in a manner such that when a first button end is in contact with the first channel end the blade member is extended to a farthest point and when a second button end is in contact with the second channel end the blade member is retracted entirely into the blade member receiving cavity.

EXEMPLARY MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is an exploded perspective view showing an exemplary embodiment of the combined key fob scraper device of the present invention generally designated by the numeral 10. Key fob scraper device 10 includes a scraper blade member 12; a snap-apart blade member housing, generally designated by the numeral 14, having first and second snap connectable housing members 16,18; and a retraction button 20.

Scraper blade member 12 is molded from high impact styrene plastic and is about one (1") inch wide, about one and three quarter (13/4") inches long, and has substantially planer upper and lower surfaces. A first one inch long beveled scraping edge 22 is formed along a first side edge 24. A second beveled scraping edge 26 having a length of about one third (1/3") inch is centrally located on a second side edge 28. Four centrally positioned retraction button engagement apertures 30 are formed along a line bisecting scraper blade member 12 along its width.

Snap-apart blade member housing 14 is formed from first and second snap connectable housing members 16,18. First and second snap connectable housing members 16,18 are constructed from high impact styrene plastic and are secured together with four snap connectors 32. With reference to FIG. 1A, each snap connector 32 includes an insertion snap portion 34, having three circumferential ridges 36, and a receiving snap portion 38 having a receiving compartment 40 sized to frictionally receive and engage a snap portion 34.

With reference once again to FIG. 1, first and second snap connectable housing members 16,18 are snapped together by aligning the four snap connectors 32 and pressing together. First and second snap connectable housing members 16,18 are disconnected by pulling apart. When snapped together, first and second snap connectable housing members 16,18 form a blade member receiving cavity 42 (also shown in FIG. 4). A key ring receiving aperture 44 is formed through an extended end 46 of each of the first and second snap connectable housing members 16,18. Key receiving aperture 44 is sized to receive a conventional key ring therethrough in a manner to allow combined key fob scraper device 10 to be used as a key fob if desired.

First snap connectable housing member 16 has a substantially rectangular retraction channel 50 formed therethrough. Retraction channel 50 has a first channel end 52 and a second channel end 54. A first plurality of ratchet teeth 56 run along a first retraction channel sidewall 58 and a second plurality of ratchet teeth 60 run along an opposite retraction channel sidewall 62.

Retraction button 20 is a substantially rectangular block of plastic having a ridged bottom surface 64 that is adapted to engage the first and second pluralities of ratchet teeth 56,60. A pair of blade member engagement protrusions 66 extend from ridged bottom surface 64 that are adapted to engage two of the four retraction button engagement apertures 30 at a time.

Key fob scraper device 10 can be assembled with blade member engagement protrusions 66 installed within the two retraction button engagement apertures 30 located adjacent second beveled scraping edge 26 when it is desired to utilize first beveled scraping edge 22 as the scraping element and installed within the two retraction button engagement apertures 30 located adjacent first beveled scraping edge 22 when it is desired to utilize second beveled scraping edge 26 as the scraping element. Scraper blade member 12 can thus be reversed to position the desired scraping edge 22,24 toward the working end of combined key fob scraper device 10.

With reference to FIG. 2, when key fob scraper device 10 is assembled, blade member 12 is fully retracted within blade member receiving cavity 42 through a blade member positioning port 70 by positioning a first button end 72 in contact with first channel end 54 (also shown in FIG. 1). With reference to FIG. 3, blade member 12 is extended to a farthest point from key fob scraper device 10 by positioning a second button 74 end in contact with the second channel end 54 (also shown in FIG. 1). When blade member 12 is fully extended the exposed scraping edge 22,26 can be used to remove the film covering from a scratch off ticket.

FIG. 4 is a cross sectional view of key fob scraper device 10 along the line IV--IV of FIG. 2 showing blade member 12 positioned within blade member receiving cavity 42. Ridged bottom surface 64 of retraction button 20 is shown in engagement with the first plurality of ratchet teeth 56.

It can be seen from the preceding description that a combined key fob and ticket scraper that has been provided that has a scraping edge adapted to scrape the entire film area from a scratch off type lottery ticket with one or two scraping movements; that has a retractable scraper member; and that has at least two distinct scraping edges with one adapted for scraping only a small area of film at a time.
