Description

TECHNICAL FIELD

The present invention relates to a ball throwing machine, and more particularly to a ball throwing machine that is easily and quickly adjustable.

BACKGROUND

In the sports of baseball and softball it can be challenging to train athletes under game like conditions. A key element of these sports is the pitch of the ball, and the subsequent reactions of both the batter and the catcher to the thrown ball. For athletes in recreational leagues or on interscholastic sports teams it can be difficult for the athletes to get the exposure to pitched ball variation and the repetitions required to improve their skills. The methods currently being used to meet the required repetitions and overall exposure to a pitched ball for training purposes varies greatly depending on the level of play and the money available to invest in training. Where little money is available for training, pitched ball repetition to both a batter and catcher can be achieved by having a coach or pitcher throw the balls. Although this form of training allows the catchers and batters to interact directly with pitched balls, the variety of ball movement, ball speeds and their repetitions are limited by the coach's or pitcher's abilities. Another option to expose athletes to pitched balls is by using a ball throwing machine. Ball throwing machines are capable of reproducing pitched ball speeds and trajectories. The one problem with existing ball throwing machines is their inability to produce pitch to pitch variation in both ball placement and trajectory. In order to change the thrown ball trajectory and location the machine operator needs to re-adjust the machine. This can require multiple steps and can sometimes require the batter to step away while the machine is being adjusted. The time taken to re-adjust the machine and the lack of pitch to pitch variation detract from the training experience.

Thus there is a need for a ball throwing machine that overcomes the above listed and other disadvantages.

DETAILED DESCRIPTION OF THE INVENTION

The disclosed ball throwing machine is capable of rapidly changing ball trajectories, positions and speeds. The design of this throwing machine allows the machine operator to freely manipulate the thrown ball's position and trajectory at will by aiming the machine using the integrated hand grip providing superior pitch to pitch variation. The versatility of this machine allows the machine to be rapidly setup and used in a wide variety of training environments providing players more opportunities to train and gain the repetitions needed to improve their skills. The disclosed ball throwing machine is different from all other ball throwing machines because of its ability to be freely manipulated by the machine operator allowing them to rapidly change the ball's trajectory, position and speed. The disclosed ball throwing machine consists of a ball throwing machine incorporating one or more ball throwing wheels. In one embodiment, the ball machine will be limited to one wheel, in this embodiment, additional wheels are not required and will actually limit functionality. To project a ball it is inserted into the throwing machine by one of two inlets or shoots to produce either topspin or backspin. The machine consists of a top shoot with the ball entering on one side to produce backspin. The throwing machine can be rapidly turned around and the ball inserted in the lower shoot to produce topspin. The rapid movement and versatility in machine positioning is achieved through the use of a ball and socket joint at the lower end of the throwing machine along with a handgrip for the operator to move the machine. This ball and socket type joint is capable of being operated in a locked position by tightening the ball against the socket housing by means of a locking screw. The machine can also be left free to move in the socket allowing the machine operator to freely aim the machine at will. The ball's spin, thrown position and trajectory are rapidly changed by the machine operator by changing the orientation of the machine. To add further versatility, the ball throwing machine also incorporates a speed selection switch to change the speed of the thrown ball.

FIG. 1 is a front perspective view of the disclosed ball throwing machine 10 installed on an adjustable stand. In one embodiment, the adjustable stand may be a tripod 14. The machine 10 comprises a housing 82, and a handle 18 attached to the housing, the handle 18 has a vertical orientation in this embodiment. The machine 10 has a first ball inlet 22, and a first ball outlet 26. The machine 10 has a second ball inlet 30, and a second ball outlet 34. The housing 82 is moveably attachable to a base 38 via a mechanical joint means. In one embodiment, the machine has a ball member 86 attached to the bottom of the housing that is removeably attachable to the tripod 14 via a base 38 located on the tripod 14. In this embodiment, the base 38 is a ball socket configured to receive the ball member 86. In another embodiment, the base 38 may be part of the machine 10, and the base being configured to removeably attach to a tripod 14, with the ball member 86 configured to fit into the base 38. There are many other types of mechanical joint means that allow lockable movement between the housing 82 and the base 38 that are included in this ball throwing machine, such as, but not limited to universal joints, pivot joints, clevis joint, etc.

FIG. 2 is a rear perspective view of the disclosed ball throwing machine 10 installed on a tripod 14. In this view a motor housing 42 is visible along with a motor control knob 46. In this view, a locking knob 40 is shown. The locking knob 40 can be tightened to lock the housing 82 with respect to the base 38. In one embodiment, the housing 82 may have a ball member 86 that is configured to fit inside the base 38, and when the knob 40 is tightened, the base 38 tightens about the ball, locking the housing 82 in place with respect to the base 38. The locking knob 40 can be loosened to allow the housing (and ball member 86) to rotate and move freely while still being attached to the base 38. Thus, the housing 82 can be moved with respect to the base 38, and then locked in position via the locking knob 40. In one embodiment, the housing 82 can rotate with respect to the base 38, pivot forward and back with respect to the base 38, pivot left to right and right to left with respect to the base 38, and pivot in any 360° direction with respect to the base 38.

FIG. 3 is a right side sectional view of the ball throwing machine 10. In this view, a wheel 50 is shown inside the machine 10. The wheel 50 is connected to a drive shaft 54. The drive shaft 54 is connected to a motor (located inside the motor housing 42). When the motor is activated it rotates the drive shaft 54 and wheel 50 in the direction shown by arrow 60. When a user places a ball 58A in the first ball inlet 22, the wheel 50, when rotating, imparts spin and velocity and forces the ball generally along the direct of arrow 62 and ejects the ball 58B out of the first ball outlet 26. Ball 58 is represented by 58A when the ball 58 is about to be placed into the machine, and by 58B after the ball has been ejected by the ball machine 10. The housing 82 may form a first ball corridor 24 that is located between the first ball inlet 22 and the first ball outlet 26. The ball 58 travels from the first ball inlet 22 through the first ball corridor 24 and out the first ball outlet 26. The outer surface 52 of the wheel 50 forms at least a portion of the floor of the first ball corridor 24. The ball 58B will have underspin as shown by the arrow 66. Conversely, when a user places a ball 70A in the second ball inlet 30, the wheel 50, when rotating, imparts spin and velocity and forces the ball generally along the direction of arrow 74 and ejects the ball 70B out of the second ball outlet 34. The housing 82 may form a second ball corridor 32 that is located between the second ball inlet 30 and the second ball outlet 34. The ball 58 travels from the second ball inlet 30 through the second ball corridor 32 and out the second ball outlet 34. The outer surface 52 of the wheel 50 forms at least a portion of the ceiling of the second ball corridor 32. The ball 70B will have topspin as shown by the arrow 78. Ball 70 is represented by 70A when the ball 70 is about to be placed into the machine 10, and by 70B after the ball has been ejected by the ball machine 10. The ball throwing machine 10 comprises a housing 82. The housing 82 is moveably attached to the base 38 via a ball member 86. The housing 82 can rotate with respect to the base 38 along the direction shown by the arrows 90, 94. In addition the housing 82 can rotate counterclockwise or clockwise in the direction of the arrow 92. Also, the housing 82 can rotate towards and away from the viewer of FIG. 3. Thus the machine 10 can be aimed to eject the ball with underspin towards a player or a target. The machine 10 can be rotated either clockwise or counterclockwise, so that the machine can be aimed to eject the ball with top spin towards the player or the target. The housing 82 is able to rotate as shown due to the ball member 86 and base 38 interaction.

Referring to FIGS. 2 and 3, the locking knob 40 can be tightened to lock ball member 86 with respect to the base 38, so that the housing 82 is locked in place with respect to the base 38. The locking knob 40 can be loosened to allow the housing 82 (and ball member 86) to rotate and move freely while still being attached to the base 38.
