Counting and scoring device

Abstract

A counting and scoring device has a housing with its interior divided into right and left chambers by a vertical partition. A wheel is vertically mounted and rotatable within each chamber of the housing using a threaded bolt and hexagonal nut. The wheels have a plurality of flat outer surfaces on which to display indicia in the form of the numerals 0 through 9 viewed through a three-sided window on each side of the top portion of the housing. Ball bearings activated by a compression spring within a tapered opening in the partition are in contact with depressions in the inside walls of the wheels below each flat surface so that as each wheel rotates a numeral is centered in a window. A hexagonal cavity within the hub portion enables the left wheel to act as a wrench to tighten the hexagonal nut when assembling the device.

DETAILED DESCRIPTION OF THE INVENTION

(18) The device 20 of the present invention may be made up of a housing configured to contain one or more rotatably affixed wheels. A typical embodiment as seen in FIG. 1 may have two wheels, each exhibiting the numerals 0 through 9. The housing 21 for this embodiment, as may be seen in FIG. 2, may have a substantially horizontal base 24. There may be a small open chamber 25 in the lower area of the housing 21 into which may be placed a weight 26, which may be optional. The chamber 25 may only be accessible through an opening 33 through the base 24 as illustrated in FIG. 17. A cover 34 substantially the size of the base may conceal the chamber 25 and may retain the weight, if used. The cover 34 may have a soft non-skid surface so the device 20 may not mar a playing surface and may remain in place during play. The cover 34 may be affixed to the base 24 by any common adhesive known in the art.

(19) There may be a central vertical partition 27 within the housing 21 separating the interior into a right chamber 28 and a left chamber 29. Two circular openings, an upper opening 30 and a lower opening 31, may be located along the median of the partition 27. Both openings may extend completely through the partition 27. The cylindrical wall 32 of the upper opening 30 may taper slightly toward the center from both sides. This may be seen in FIG. 16 and will be explained below. The lower opening 31 may be at the substantial midpoint of the partition 27 and may have a straight cylindrical interior wall. The housing 21 may contain a right wheel 22 disposed in the right chamber 28, and a left wheel 23 disposed in the left chamber 29, both oriented such that a central opening 35 in each wheel 22, 23 may communicate with the lower opening 31 in the housing partition 27.

(20) There may be a front surface 36 and a rear surface 37 of the housing 21 which may extend upward from and be coextensive with the base 24 and with a substantially flat upper surface 38. The upper surface 38 may be used to display indicia if desired. Lateral extensions 39 from both sides of the front 36 and rear 37 surfaces may form a three-sided viewing window 40 with the sides of the upper surface 38 on each side of the housing 21.

(21) The two wheels 22, 23 may be alike except for their outside portions which will be described below. The wheels 22, 23 may be substantially circular with a thickness sufficient to display numerals on their outer surfaces. The outer surfaces may be in the form of ten equivalent flat areas such that the wheels 22, 23 may be a regular decagon in cross section. This configuration may provide ten flat surfaces 41 on each wheel 22, 23 on which to place the numerals 0 to 9. Any other configuration may be used depending upon the number and type of indicia to be displayed on the wheels.

(22) The outward facing hub portion of the wheels 22, 23 may be substantially open and there may be a wall 42 on the inside of each wheel facing the partition 27 when the wheels are mounted. The walls 42 may have a central opening 35 which may communicate with the lower opening 31 in the housing partition 27. The surfaces of the walls 42 may have a series of depressions 43 in the shape of a segment of a sphere. The depressions 43 being situated equidistantly below the substantial center line of each flat outer surface 41 of each wheel 22, 23 thereby forming a circle of depressions 43 around both walls 42. The series of depressions 43 may be disposed to cooperate with the upper opening 30 in the housing partition 27 as the wheels are rotated. A raised rim 46 may be situated about the outer edge of each wheel 22, 23, and may be segmented to form a turning surface to facilitate rotating the wheels 22, 23. See FIGS. 6 through 13.

(23) The hub portion of the right wheel 22 may be in the form of a circular cavity 47 in communication with the central opening 35 in the wall 42. The hub portion of the left wheel 23 may have a hexagonal cavity 48 in communication with the central opening 35 in the wall 42.

(24) Also disposed within the housing may be two ball bearings 51 and a compression spring 52, seen in FIGS. 5, 15 and 16. A threaded bolt 53 of sufficient length to extend through the left wheel 23, the housing partition 27 and the right wheel 22, and a hexagonal nut 55 may be used to rotatably mount the wheels 22, 23 to the housing 21. The circular cavity 47 in the right wheel 22 may accept the head 54 of the threaded bolt 53. A washer 56 may be used between the head 54 of the threaded bolt 53 and the surface of the wheel wall 42 within the circular cavity 47 to prevent wear on the surface. The shank of the threaded bolt 53 may extend into the circular cavity 47 and through the central opening 35 in the right wheel 22, the lower opening 31 in the housing partition 27, the central opening 35 in the left wheel 23 and into the hexagonal cavity 55 in the left wheel. The walls of the hexagonal cavity 48 in the left wheel 23 may be configured to accept the hexagonal nut 55 such that the hexagonal nut 55 cannot rotate within the hexagonal cavity 48. These structures may be seen in FIGS. 3, 4, and 5.

(25) To assemble the device 20 the housing 21 may be turned so that the left chamber 29 is facing upward. One ball bearing 51 may be placed into the upper opening 30 in the housing partition 27. The ball bearing 51 will not pass all the way through the upper opening 30 because of the tapering inward of the inside wall 32. The left wheel 23 may be placed into left chamber 29 of the housing 21 and aligned so that the central opening 35 in the wheel 23 is in communication with the lower opening 31 in the housing partition 27. The hexagonal nut 55 may then be placed into the hexagonal cavity 48 so that it may rest against the wall 42 and be held securely by the hexagonal configuration of the cavity 48.

(26) The left wheel 23 may be held in place using one or more fingers while maintaining the hexagonal nut 55 within the hexagonal cavity 48, and the housing 21 turned over so that the right chamber 29 may be facing upward. The compression spring 52, sized to pass through the inward tapered interior wall 32, may be placed into the upper opening 30 to come in contact with the ball bearing 51 previously placed into the left side and maintained in opening 30 by the proximity of the left wheel 23. The second ball bearing 51 may then be placed into the upper opening 30 from the right chamber 28. The compression spring 52 may exert sufficient force on both ball bearings 51 so they are situated partially outside the upper opening 30 on both sides of the housing partition 27.

(27) The right wheel 22 may then be placed into the right chamber 28 aligning the central opening 35 with the lower opening 31 in the partition 27. The washer 56 may be placed into the circular cavity 47 in the right wheel 22, followed by the insertion of the threaded bolt 53 and extending it through the central opening 35 in the right wheel 22, the lower opening 31 in the housing partition 27 and through the central opening 35 in the left wheel 23 and into the hexagonal cavity 48.

(28) Holding the right wheel 22 close to the housing partition 27, the threaded bolt 53 may be rotated using a screw driver or a finger, until the bolt 53 is in cooperation with the hexagonal nut 55. At this point, with the bolt 53 held fast, the left wheel 23 may be rotated, as a wrench, and with it the hexagonal nut 55, until the two wheels 22, 23 are firmly mounted within the housing 21. The wheels 22, 23 may be in spaced relation on both sides of the housing partition 27 so that the ball bearings 51 on each side of the partition 27 may be disposed within one of the depressions 43 in the walls 32 of each wheel 22, 23. At this point the wheels may be independently rotated and a clicking sound may be heard as the ball bearings 51 pass from one depression 43 to the next urged by the compression spring 52. As the click is heard, a flat surface 41 of the wheel with a numeral on it will be centered within the three-sided window 40.

(29) Decals or other form of cover may be placed over the exterior surfaces of the device 20 and may also be utilized to place the desired numerals on the flat surfaces 41 of each wheel. The decals on the exterior of the device 20 may be for decoration, advertisement, or game enhancement. Typical shapes of such decals may be in a contoured shape 59 to cover the entire exterior surface of the housing 21 and round 60 to cover the exterior of each wheel 22, 23. These may be seen in FIGS. 5 and 14. Other shapes may be utilized according to the indicia to be displayed.

(30) In the embodiment described and illustrated herein the ball bearings 51 may be 3.5 mm in diameter and the compression spring 52 may be 3.4 mm in diameter so the spring may pass through the upper opening 30 in the housing partition 27 and the ball bearings may be placed into the openings but will not pass all the way through. This configuration may facilitate the assembly of the device 20 as described in detail above and may be seen in FIGS. 15 and 16.

(31) The device 20 of the present invention may be made of any rigid material. An injection molded polymeric material may be ideal for this purpose. The material chosen may be sufficiently strong so that repeated rotation of the wheels and movement of the ball bearings will not create wear on the partition or the wheels.

(32) While one embodiment of the present invention has been illustrated and described in detail, it is to be understood that this invention is not limited thereto and may be otherwise practiced within the scope of the following claims.
