Description

FIELD OF THE INVENTION

The present invention is a bowling device to enable a physically impaired individual to propel a bowling ball down a bowling alley without physically grasping the bowling ball.

BACKGROUND OF THE INVENTION

The game and sport of bowling has origins dating back over 5,000 years and now there are over 100 million people in over ninety (90) countries that participate in bowling. Bowling is among the most popular forms of recreation in the world . . . The Bowling Aid extends the ability of the physically impaired to enjoy bowling. Including children
Conventional modifications comprise installing deflection means in the gutters along both sides of the lane that prevent the bowling balls from dropping into the gutters. These deflection methods allow the bowling ball to avoid the gutters and reach the pins in every release of the ball. Other means for assisting physically impaired individuals to bowl are elevated ramp that use gravity to accelerate the ball as it descends down the ramp to the bowling pins. Although both of these methods address certain challenges of the physically impaired, there is still a need for a more sophisticated form of assistance that allows bowlers to simulate the traditional methods of bowling and enjoy bowling competitively with friends, family and associates. These individuals include those simply lacking the strength to release the ball with sufficient energy to transit the entire lane, such as children, someone injured, or those persons suffering from an ailment like arthritis. The prior art reflects many attempts to address these issues, however, no one, has completely satisfied the requirements for simulating a method of bowling that reflects the game and sport of bowling.
U.S. Pat. No. 5,271,619 discloses a dolly having a pedestal means above and a roller means beneath for effecting a linear direction of motion to the dolly. The shaft means is mounted through the pedestal means and rollers coupled to one end of the shaft means for contacting a bowling ball to be rolled. A handle means is coupled to the other end of the shaft means for imparting a motion to the rollers through the shaft. However, it does not provide a means for spinning the bowling ball upon its release and lacks balancing.
PCT Application WO2005082476 discloses a personal mobility vehicle to enable the physically challenged to participate in a bowling game by means of a ramp extending between an upper end and a lower end and a coupling securing said ramp to the personal mobility vehicle. The bowling ball is launched by traveling from said upper end to the lower end of said ramp by quickly decelerating the speed of the mobility vehicle thereby, propelling the bowling ball. However, this device is too complex to be manufactured and serviced for commercialization due to various constraints, including, cost, size, weight, integrity, and the space required for storage.
U.S. Design Pat. No. D364905 discloses an ornamental design for a bowling aid device. However, it does not provide an adjustable mechanism for the height of the operator, a mechanism for spinning the bowling ball and the support plate of the design lacks a suitable shape for effectively holding the bowling ball during acceleration to the point of release.
U.S. Pat. No. 4,470,598 discloses a devise for a bowler in a wheelchair Said devise is placed alongside of the wheelchair as a standing frame and has a declining ramp wherein the bowler manually positions the frame to achieve directional control of a bowling ball at launch. A ball is placed on the launching ramp and released by the bowler. However, this device is complex with manufacturing constraints that are barriers to commercialization including cost, size, storage, integrity, and durability,
U.S. Pat. No. 7,244,201 discloses a stick for playing a game with a spherical ball wherein a stick is used for propelling and controlling the ball over a flat playing surface. The stick includes a body having a downwardly facing cup-shaped -spherical depression and a shaft allowing a running or skating player to propel and control the ball. However, this device lacks an adjustable mechanism for the height of the operator and does not provide a means for spinning the bowling.
U.S. Pat. No. 3,365,197 discloses an elongated bowling ball handle of sufficient length to allow the bowler to operate in an erect position. The bowling ball handle having one element within an open recess therein to receive three fingers of the bowler's hand, the fourth finger extending along the element to guide the same. However, said devise does not spin the bowling ball, nor have an adjustable mechanism for the height of the bowler.
U.S. Pat. No. 3,033,567 discloses a bowling ball rolling device which may be used by handicapped persons who have suffered a loss of a thumb or fingers. Said device enables the bowler to compensate for these handicaps. A semi spherical, cup-shaped receptacle which receives the balanced bowling ball, which receptacle has a means associated therewith for receiving the hand of the user, the receptacle and ball carried thereby are being controlled by the user of the device. However, it does not spin the bowling ball upon its release and the weight of the ball rest totally on the user's wrist creating discomfort to the player.
It is therefore desirable to provide an improved apparatus for assisting mildly physically challenged bowlers to release the ball, such as the elderly and children. In general, several aspects the invention features are an improved apparatus for applying a spin to the bowling ball upon its release to ensure a hooked path as the ball transits the bowling lane, providing an improved apparatus that is adjustable for the height of the bowler, and an improved apparatus that is simple for the operator to use.
In still another aspect, the invention improves on the prior art by the elimination of other features which produce a bowling aid that is simple to use, cost effective to manufacture, weights less, has the ability to simulate standard bowling practices, and stores easily. The foregoing has outlined some of the pertinent improvements over the prior art relative to the present invention. These features should be construed as being merely illustrative of some of the more prominent individual and measurable properties of the present invention that simplify and improve upon the prior art. Many other beneficial elements can be obtained by applying the disclosed invention in a different manner or modifying the invention within the scope of the claims, summary and the detailed description describing the preferred embodiment of the invention.

DETAILED DESCRIPTION

Referring to FIGS. 1-12 are diagrams depicting a various views of a first embodiment of a bowling device 10 for propelling a bowling ball 12 along an alley 14 for striking one or more bowling pins 16. The bowling ball 12 includes a spherical shape 18 and has a smooth exterior surface 20. Typically, a bowling ball 12 will include a set of three holes 22 drilled into the bowling ball 12 from the smooth exterior surface 20. The set of three holes 22 may include a ring finger hole 24, a middle finger hole 26, and a thumb hole 28. Typically, an individual 30 will grasp the bowling ball 10 with a hand 32 by inserting a ring finger 34, a middle finger 36 and a thumb 38 into the ring finger hole 24, middle finger hole 26 and thumb hole 28, respectively. The individual 30 then utilizes an arm 40 to produce a forward motion for propelling the bowling ball 10 down the bowling alley 14 and striking the one or more bowling pins 16. The bowling device 10 eliminates the need for the individual 32 to physically grasp the bowling ball 10 while producing a forward motion for propelling the bowling ball 10 down the bowling alley 14 and striking the one or more bowling pins 16.
The bowling device 10 comprises a base 50 defining an upper side 52 and a lower side 54. Preferably the base 50 includes a metallic plate 58, polymeric plate or other rigid plate material. A rotating device 60 defines a generally longitudinal line of symmetry 61 shown as line “A” and is secured to the lower side 54 of the base 50 for permitting the base 50 to more easily traverse over the bowling alley 14. The rotating device is shown to include a truck 62. The truck 62 defines a base plate 64 secured to the lower side 54 of the base 50 and a hanger 66. An axle 68 traverses the hangar 66 for defining a first wheel axle shaft 70 and a second wheel axle shaft 72. A first set of wheel bearings 74 engaged about a first wheel 76 for permitting the first wheel 76 to rotatably engage the first wheel axle shaft 70. A second set of wheel bearings 78 engage about a second wheel 80 for permitting the second wheel 80 to rotatably engage the second wheel axle shaft 72. The second wheel axle 72 and wheel assembly of the truck 62 is optionally provided with a braking means for both the front wheel axle 70 and rear wheel axle 72 assemblies as is well known in the art. Additionally, the handle-controlled truck can be controlled by a steering mechanism, for providing smooth maneuvering. The steering mechanism may be comprised with a casing fixed at front end of the truck and a front wheel assembly and a rear wheel assembly respectively mounted at front and rear ends of the truck, wherein, the front wheel assembly 76 including two wheels, which are able to steer and control the direction of the truck.
The base plate 64 and the hanger 66 are coupled by a bushing coupling 82 and a ball joint coupling 84. The bushing coupling 82 includes a kingpin 86 that traversing a grommet 88 for permitting a spring mechanism 90. The spring mechanism 90 permits the hanger 66 to pivot relative to the base plate 64 for steering the base 50. The kingpin 86 may be utilized for compressing the bushing coupling 82 to stiffen the bushing coupling 82 and provide a more resistance pivoting between the hanger 66 and the base plate 64. Alternatively, the kingpin 86 may be utilized for expanding the bushing coupling 82 for reducing the stiffness of the bushing coupling 82 and providing less resistance pivoting between the hanger 66 and the base plate 64.
A support plate 100 engages the base 50 for supporting the bowling ball 12 above the bowling alley 14 such that the bowling ball may be wheeled in multiple directions over the bowling alley 14. The support plate 100 defines a top end 102, a bottom end 104, an upper surface 106, a lower surface 108, a generally longitudinal axis of symmetry 110 and a generally lateral axis of symmetry 112. The generally longitudinal axis of symmetry 110 is shown as line “B” and the generally lateral axis of symmetry 112 is shown as line “C”. Preferably the support plate 100 includes a metallic plate 58, polymeric plate or other rigid plate material. The lower surface 108 of the support plate 100 is secured to the upper side 52 of the base 50. The generally longitudinal axis of symmetry 110 and the generally lateral axis of symmetry 112 have a perpendicular orientation 114. The support plate 100 includes a generally spherical shaped cup 116 for conforming to the spherical shape 18 of the bowling ball 12 and retaining the bowling ball 12 during movement of the base 50. More specifically, the support plate 100 has a longitudinal concave curvature 120 relative to the generally longitudinal axis of symmetry 110 for conforming to the spherical shape 18 of the bowling ball 12 and retaining the bowling ball 12 during movement of the base 50. Furthermore, the support plate 100 has a lateral concave curvature 122 relative to the generally lateral axis of symmetry 112 for conforming to the bowling ball 12 and retaining the bowling ball 12 during movement of the base 50.
The bowling ball 12 separates from the support plate 100 upon deceleration of the base 50 in a forward direction to propel the bowling ball 12 thereby. The top end 102 of the support plate 100 defines convex edge 124 for conforming to the bowling ball 12 and retaining the bowling ball during forward movement of the base 50. Furthermore, the bottom end 104 of the support plate 100 may define concave edge 126 for conforming to the bowling ball 12 and retaining the bowling ball 12 during rearward movement of the base 50. The concave edge 126 may be positioned between a first arm 130 and a second arm 132. The generally spherical shaped cup 116 including the convex edge 124, concave edge 126, first arm 130 and second arm 132 assists to stabilize the bowling ball 12 within the support plate 100 and prevent the bowling ball 12 from disengaging from the support plate 100 when the support plate 100 is elevated above the bowling alley 14. The individual 30 is capable of displacing the base 50 along the bowling alley 14 by grasping a shaft 140.
The shaft 140 extends between an upper end 142 and a lower end 144. The upper end 142 of the shaft 140 includes a handle 154 for engaging the individual 30. The shaft 140 includes an upper shaft 146 and a lower shaft 148 both defining an interior bore 150 and an exterior surface 152. The upper shaft 146 is slidably engaged within the interior bore 150 of the lower shaft 148 for varying a distance between the base 50 and the handle 154 from a first shaft length 156 to a second shaft length 158. A clamp 160 having a clamp arm 162 for compressing and expanding the clamp 160 engages around the exterior surface 152 of the lower shaft 148 for compressing the lower shaft 148 against the upper shaft 146 and terminating the sliding engagement between the upper shaft 146 and the lower shaft 148. As best seen in FIG. 5, during the clamp arm 162 in the expanded position, the upper shaft 146 may be rotatably engaged within the interior bore 150 of the lower shaft 148 for varying an angle between the base 50 and the handle 154 from a first handle angle 164 and a second handle angle 166. Similarly, the clamp arm 162 compresses the lower shaft 148 against the upper shaft 146 and terminates the rotating engagement between the upper shaft 146 and the lower shaft 148.

The tube portion 172 defines an interior bore 176 and an exterior surface 178. The tube portion 172 is slidably engaged within the interior bore 150 of the lower shaft 148 of the shaft 140. Preferably the coupler 170 includes a tubular shaft consisting of metallic, polymeric or other rigid material. A retractable pin 180 traverses the exterior surface 178 of the tube portion 172 and the exterior surface 152 of the shaft 140 for terminating displacement between the shaft 140 and the base 50. The fusing portion 174 comprises an affixing means such as a metallic welding for fusing the metallic base 50 with both the support plate 100 and the coupler 170. As best seen in FIGS. 4 and 7, the upper end 142 of the shaft 140 including an accurate portion 190 for positioning the handle 154 in a generally horizontal position 192 upon the support plate 100 being elevated above the bowling alley 14. The accurate portion 190 improves the comfort of the individual by positioning the hand 32 of the individual 30 in a horizontal position when the support plate 100 is elevated above the bowling alley 14. Furthermore, the accurate portion 190 improves the comfort of the individual by positioning the hand 32 of the individual 30 in a general incline position 194 upon releasing the bowling ball from the support plate.
In the first embodiment of the invention, the generally longitudinal line of symmetry 61 of the rotating device 60 and the generally longitudinal axis of symmetry 110 of the support plate 100 define an aligning orientation 200 for centering the support plate 100 over the rotating device 60. The aligning orientation 200 positions the center mass 13 of the bowling ball 12 shown as line “D” equally between the first wheel 76 and the second wheel 80.
Referring to FIGS. 13-22 are diagrams depicting a second embodiment of the bowling device 10 for propelling a bowling ball 12 along an alley 14 for striking one or more bowling pins 16. In FIGS. 15-25 the generally longitudinal line of symmetry 61 of the rotating device 60 and the generally longitudinal axis of symmetry 110 of the support plate 100 which defines a non-aligning orientation 202 for offsetting the support plate 100 relative to the rotating device 60. The non-aligning orientation 202 positions the center of mass 13, line “D” of the bowling ball 12 off-center between the first wheel 76 and the second wheel 80. The non-aligning orientation 202 facilitates rotating or pivoting 204 the support plate 100 during the bowling ball 12 separating from the support plate 100 for creating both a longitudinal rotational spin 214 and a lateral rotational spin 216 on the bowling ball 12. Both a longitudinal rotational spin 214 and a lateral rotational spin 216 on the bowling ball 12 result in a curved trajectory of the bowling ball 12.
Referring to FIGS. 18-20 are diagrams depicting the support plate 100 including a left non-aligning orientation 208 for facilitating a left rotational force 209 upon the support plate 100 and a left lateral rotational spin 220 upon the bowling ball 12. FIGS. 21 and 22 illustrate the support plate 100 including a right non-aligning orientation 211 to facilitate a right rotational force 213 upon the support plate 100 and a right lateral rotational spin 222 upon the bowling ball 12. The support plate 100 may further include a finger shaft 210 extending from the upper surface 106 of the support plate 100. The finger shaft 210 engaging within one of the set of three holes 22.

The circular cross-section 212 of the finger shaft 210 is slightly less than the circular cross-section 23 of one of the set of three holes 22. The finger shaft 210 retains the bowling ball 12 during acceleration of the base 50 in a forward direction and releasing the bowling ball 12 during deceleration of the base 50 in a forward direction to propel the bowling ball 12 thereby. Furthermore, the finger shaft 210 prevents the bowling ball 12 from rotating during rotating or pivoting 204 the support plate 100. Upon the deceleration of the base 50, the one of the set of three holes 22 separates from the finger shaft 210 thereby transferring the rotational force 204 of the support plate 100 to the rotational spin 206 upon the bowling ball 12.
Referring to FIGS. 15-25 are diagrams depicting the handle 154 which may include a fork portion 230 having a first fork element 232 and a second fork element 234. A cross-bar 236 extends between the first fork element 232 and the second fork element 234 for receiving the hand 32 of the individual 30. The cross-bar 236 has a generally perpendicular orientation 238 relative to the shaft 140 for facilitating rotating or pivoting 204 the base during the bowling ball 12 separating from the support plate 100 for creating rotational spin 206 upon the bowling ball 12. FIGS. 15-22 include positioning of the finger shaft 210 adjacent to the top end 102 for defining an upper finger shaft 240. The upper finger shaft 240 is most effective wherein the forward acceleration force 134 and/or rotating or pivoting force 204 upon the support plate 100 is minimal.
Referring to FIGS. 23-25 are diagrams depicting positioning of the finger shaft 210 generally equidistant between the top end 102 and the bottom end 104 for defining a middle finger shaft 242. The middle finger shaft 242 is more effective wherein the forward acceleration force 134 and/or rotating or pivoting force 204 upon the support plate 100 is maximum. Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
Referring to FIG. 26 is a diagram depicting a pivoting action of the support plate with respect to base plate. The support plate 100 is secured to the main shaft 256 by using a securing member 250. A pivotable member 244 is attached to the base plate 50 and the main shaft 256 is secured to the pivotable member 244. The lower shaft 148 and the upper shaft 146 are adjustably connected together by means of a clamp 160.
