Description
BINGO CHIP
This invention relates to a bingo chip which contains a ferromagnetic ring so that the bingo chip can be attracted by a magnet to facilitate handling of such bingo chips.
When playing bingo, it is of course required to have a marker to maxk off the called numbers on a bingo card. Preferably, the marker is transparent so that a player can double check the numbers beneath the chips.
Since such chips are typically coloured for easy recognition, and they must not be too thick otherwise their overall transparency becomes significantly decreased and hence leads to difficulty in double checking called numbers. The thinness of such bingo chips leads to difficulties in handling them, par-ticularly when a large number of chips are required, forexample where a player is playing a number o~ cards simultaneously. A convenient way of handling such chips is to provide a ferromagnetic substance therein and a permanent magnet in the form of a wand, so that the chips will be readily attracted to such wand. When a player is playing a bingo game with such ehips, which are typically circular in shape, they are placed one by one by hand over the called numbers on the card or cards in the usual mannerO When the bingo game is finished . ~
and the player wishes to clear the cards he is playing, the wand is simply drawn over adjacent the surface of the cards thereby causing such chips to adhere to the wand. The chips are then readily removed from the wand by a simple stroke of the hand so as to cause them to fall into a suitable receptacle. It may be necessary to pass the wand over the cards more than once. However, all of the chips will be fairly readily removed from the cards without the necessity of pickinq each up one by one, which i5 fairly difficult bearing in mind the rela-tive thinness of the chips.
A number of bingo chips containing a Eerro magnetic element have been described in the past. For example U.S. Patent No. 3,684,288 to Grace issued on August, 1972 describes such a chip wherein the ferro-magnetic element consists o ferromagnetic particles disposed throughout the plastic chip body. U.S. Patent No. 4,019,747 to Chuilli issued on April, 1977 describes a bingo chip wherein the ferromagnetic element consists of an annular ring connecked to and extending beyond the outer periphery of the plastic chip body, or wherein the chip body has a central hole with the annular ring con-nected to the periphery of such hole and extending inward therefrom. A difficulty with the bingo chip of the Grace patent is that as the particles are spaced apart, they do not effectively conduct magnetic field between one another so that when a magnet contacts an edge of such a chip, a further edge or face of such a chip not in contact with the magnet will not effectively attract and retain another such chip thereagainst. Thus for a given size magnet, less chips can be attracted to it than would be the case if the magnetic field was con-ducted efficiently through the chip by the ferromagnetic element. The bingo chip of the Chuilli patent wherein the ferromagnetic ring is attached to the outer periphery of the plastic chip body, overcomes the foregoing problem but in itself produces three new problems. First the ferromagnetic ring will tend to scratch the typically relatively soft plastic bodies of adjacent chips when the chips are together in a recep-~able, thereby resulting in decreased transparency ofthe chips with use. In addition, particularly in the case of a player playing a larger number of cards for a substantial period of time, the ferromagnetic ring which is typically steel will contact the player's fingers repeatedly and tend to stain them black, which stain is difficult to remove. Further, the exposed edges of such ferromagnetic ring, being relatively thin, tend to be left fairly sharp by the manufacturing process so that such could injure the player's fingers. In the case of the bingo chip of the Chuilli patent wherein the ring is disposed in the central hole, there is of course no 6~
eficient conduction of the magnetic field from one part of the edge of the chip ~o another part of the edge thereof, and in addition the ferromagnetic ring in such a position tends to at least par~ially block the number on a card over which the chip is placed.
Subsequent U.S. Patent No. 4,172,597 to Grace et al issued on October, 1979, provides a ferromagnetic mesh or screen disposed within the chip body. Such screen assists in conducting the magnetic field from one portion of the edge of the chip to other portions thereof since the screen is continuous, although not as much as may be desired due to the relatively thin strands of the wire making up the mesh. A disadvantage of this chip though however~ i5 the same as in the chip of the Grace '288 patent; that is that the mesh now tends to partially obscure a number of a bingo card over which the chlp is disposed. Recently issued U.S. Patent Mo. 4,395,043 to Gargione returns to the concept of a ring, but attempts to overcome possible sharp edges which may be presented to A player's fingers, as well as difficulty in attaching the ring to the chip body, by providing the ring with 1anges which overlie and con-tact adjacent portions of respective aces o the chip body. However, the ferromagnetic ring again typically of steel, will still contact a player's fingers tending again to stain them black as described after prolonged 7~
playing on a number of cards simultaneously. Further, such a chip may be relatively difficult to manufacture, the patent not describing the manufacturing technique.
U.S. Patent No. 1,605,703 to Brown does describe a checker with a ferromagnetic ring disposed in the body thereof. However, in such checker the ring is spaced inward from the outer periphery thereof and hence does not readily facilitate edge to edge attraction of such devices when a magnet is placed against a portion of an edge of one of them.
It would be desirable then, to provide a bingo chip with a ferromagnetic element disposed therein, which will not present a potential hazard to the fingers of a player whether through potentially sharp edges or simply through contact with the player's fingers thereby staining them black, which will allow a number on a bingo card over which the chip is placed to be readily read, and which will be fairly readily manufactured.
The present invention provides a bingo chip which comprise~ a transparent chip body having opposed faces, and a ferromagnetic ring. The ferromagnetic ring extends adjacent substantially the entire outer periphery of the chip body, and is affixed between the faces of the chip body. An outer periphery of the ring does not extend beyond the outer periphery of the chip body.
The outer periphery of the ferromagnetic ring is preferably flush with the outer periphery of the chip body. Further, the chip body is preferably circular and the ferromagnetic ring annular.
A method of making a bingo chip as described is also provided. The method comprises forming a transparent chip body about a hole in a ferromagnetic sheet such that the ferromagnetic sheet is affixed bet-ween opposed faces of the chip body, and substantially the entire outer periphery of the chip body extends beyond the periphery of the hole, with a portion of the ferromagnekic sheek adjacent to at least a portion of the outer periphery of the chip body being left unco-vered by the chip body. Following this, the ferromagne-tic sheet is then trimmed flush with the outer periphery of the chip body. Prefarably, the chip body is formed such that a portion o th~ ferromagnetic sheet substan-tially surrounding the entire outer periphery of the chip body is left uncovered by the chip body.
The method preferably comprises making a plura-lity of chips simultaneously in the manner described.
The method may usefully addltionally comprise the step of forming the holes in th~ ferromagnetic sheet prior to forming the chip bodies. Of course, a par-ticular manufacturer might obtain the ferromagnetic sheet with the holes already formed therein.
The preferred method of trimming as described, is performed by punching the ferromagnetic sheet flush with the outer peripheries of the chip bodies.
The ferromagnetic sheet may be of a variety of shapes, although rectangular is preferred.
Embodiments of the invention will now be described with reference to the drawings in which:
Figure 1 is a plan view of a ferromagnetic sheet with holes therein used in the making of chips of the present invention;
Figure 2 is a vertical cross-section along a portion of a mold shown forming the chip bodies about the ferromagnetic sheet of Figure l;
Figure 3 is a perspective view of a portion of the ferromagnetic sheet with the formed chip bodies ther~on;
Figure 4 is a vertical cross section of a punch and die apparatus being utilized to produca chips of the present invention from the sheet of Figure 3;
Figure 5 is a perspective view of a chip of the present invention produced from the punch and die shown : in Figure 4; and Figure 6 is a vertical cross section along the line 6-6 of Figure 5.
Referring first to Figure 5, a bingo chip 2 of the present invention i~ shown. The chip consists of a : 7 : ;
circular transparent, usually coloured, plastic chip body 3 with an outer edge or periphery 5. An annular ferromagnPtic ring 6, typically made of soft steel, extends around the outer periphery 5 of chip body 3, and is fixed between opposite faces 4 of chip body 3 by being embedded within chip body 3. Ring 6 has an inner edge or periphery 7, and an outer edge or periphery 8~
the outer periphery 8 being flush with outer periphery 5 of chip body 3.
The method of making the bingo chip 2 as shown in Figures 5 and 6, will now be described with reference to Figures 1 through 4, the sequence of steps proceeding in numerical order through those figures. First, a plurality of circular holes 10 are formed in sheet 9, typically by punching out holes 10 kherefrom. Sheet 9 is then positioned by suitable stops tnot shown~ between opposed half sections 14 and 20 of a mold 12. Half sec-tions 14 and 20 are provided with mating circular cavi-ties 16 and 22 respectively, which together define circular mold cavities 23. Sheet 9 is disposed with the centres of holes 10 being disposed in the centres of mold cavities 23 such that ~he outer edge or outer periphery 24 of each mold cavity 23 extends beyond the periphery of each corresponding hola 10~ Suitable means (not shown~ for injecting a suitable transparent, coloured plastic to form chip body 3, are provided.
7~
Following forming of chip bodies 3 in mold 12, and remo-val of mold 12, sheet 9 is left with a plurality of spaced apart chip bodies formed thereon. As shown in Figure 3, sheet 9 will now be affixed or embedded bet-ween opposed faces 4 of each chip body 3. Of course, asmold cavities 23 are spaced apart, there will be por-tions of sheet 9 which surround the entire outer periphery 5 of each chip body and which are left unco-vered by the chip bodies 3.
Chip bodies 3 with sheet 9 embedded therein, are no~ positioned in a punch and die arrangement asshown in Figure 4. A plurality of cylindrical punches 26 are provided which may be connected to a common upper platen (not shown). Punches 26 have diameters the same as respective chip bodies 3 so that outer peripheries 28 of punches 26 are aligned with outer peripheries 5 of chip bodies 3. In addition the punch and die arrange-ment includes a lower platen 30 which has circular holes 32 of a diameter substantially the same as chip bodies 3, so that lower portions of chip bodies 3 will rest within holes 32 with the outer peripherie~ 5 of chip bodies 3 being substantially flush with the surfac~ of holes 32, and sheet 9 resting on an upper surface 31 of lower platen 30. Lower platen 30 is also provided with diverging openings 34 communicating with openings 32.
Pressing punches 26 downward causes sheet 9 to be punched off flush adjacent the outer peripheries 5 of chip bodies 3, thereby resulting in bingo chips ~ which will then fall through openings 32 and flared openings 34.
It will be appreciated that die platen described above can be replaced by a known type of die platen which includes spring loaded cylinders disposed beneath the upper openings of such platens, so that when punches 26 are drawn upward following punching o sheet 9~ formed bingo chips 2 are then ejected by such spring loaded cylinders.
As will be apparent to those skilled in the art in light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spixit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance wi~h the sllbstance deined by the following claims.
When bingo chips 2 ar~ in use, as the metal rings 6 do not contact a player's fingers, such will not be stained by those chips 2. In addition, there is little likelihood o exposed metal edges which could cut a player's fingers, or cause scratching of adjacent chips 2 when such are stored in a common container. The continuous ferromagnetic ring 6 will of course assist in conducting a magnetic ~ield around the outer periphery o~
~ 3 the chip body, so ~hat an edge of one chip 2 adjacent a magnet, can adhere to an outer periphery of an adjacent chip 2.
