Description

BACKGROUND OF THE INVENTION

The present invention relates to sports training apparatuses for launching a sports ball, and more specifically to improvements in traditional sports ball launching apparatuses. In particular, the invention relates to a sports training apparatus with the ability to launch a ball, such as, for example, a soccer ball or a volleyball, at a plurality of power levels, at a plurality of different angles, with a plurality of different types of spin, and can be remotely controlled or programmed with a pre-determined launching pattern. Additionally, the sports training apparatus can be powered by batteries allowing for use in remote locations.
The present invention is an improvement over U.S. Pat. No. 5,911,214 issued Jun. 15, 1999 wherein a soccer ball projecting apparatus is disclosed. Further developments have been revealed that outline the need for the production of an upgraded ball projecting apparatus. For a ready understanding of the current state of the soccer ball projecting apparatus, the reader is directed to U.S. Pat. No. 5,911,214.
To become proficient at any sport, it is necessary to practice for countless amounts of hours to be able to develop the skills to perform difficult fast paced moves with split second timing and accuracy. Not only is there a need to repeatedly practice a single manoeuvre a multitude of times to become proficient, but there is also a need to practice a series of different maneuvers in succession to simulate real in-game situations. Generally, in traditional sports ball launching devices, the apparatus is only capable of providing a single repetitive launch type unless the specific settings are manually changed between launches, which does not accurately represent true in game situations. Different launch type settings may include projecting the sports ball at different power levels, at different angles (i.e., different directions) and with different spins on the ball (i.e. ability to curve the sports ball).
United States Patent Application No. 2008/0032828 published Feb. 7, 2008 (Alger) discloses a system for delivering objects, such as soccer balls for training purposes. The delivery device includes an accelerator that accepts, accelerates and launches the ball with motion characteristics, such as linear acceleration, angular acceleration, or a combination of both. The balls are accelerated using a fly wheel system similar to most baseball pitching machines. The assembly adjusts the position of the accelerator to adjust the exit trajectory of the object including adjustment about the yaw axis, elevation axis and a spin axis of the ball. The device can be remotely controlled wirelessly through a radio frequency receiver and transmitter. The delivery device also includes an electronic control system having stored training programs for selective use and executed in either pre-programmed or real-time-selected sequences. Additionally, the power source is portable utilizing one or more rechargeable batteries.
U.S. Pat. No. 6,488,020 issued Dec. 3, 2002 (Rosas-Magallan) discloses a training machine which projects soccer balls by means of propelling wheels. The machine propels balls with a maximum degree of freedom in selecting ball trajectories at various angles, distances and velocities. An electrical control regulates the speed of each of the propelling wheels, providing a variety of spin control to the ball.
United States Patent Application No. 2005/0103318 published May 19, 2005 (Leal et al.) discloses a sports ball throwing apparatus utilizing compressed air to project the sports ball. The apparatus is adjustable in both the azimuth and elevation for launching in various directions and also has a means for adding a spin to the sports ball.
United States Patent Application No. 2002/0185120 published Dec. 12, 2002 (Scott) discloses a baseball pitching system for allowing an individual to operate a baseball pitching machine similar to an actual human pitcher. The system includes a central processing unit which manipulates the velocity of the pitching wheels to create the desired pitch. Pre-programmed pitching sequences and random pitching sequences may be entered into the system central processing unit.
The present invention was conceived and developed having regard to the known prior art and with the purpose of providing an improved sports training apparatus with the ability to project a ball, and more specifically, a soccer ball or a volleyball, at a plurality of power levels, at a plurality of different angles, with a plurality of different types of spin, and can be remotely controlled or programmed with a pre-determined launching pattern.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A better understanding of the present invention and its objects and advantages will become apparent to those skilled in the art from the following detailed description, wherein there is described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated for carrying out the invention. As will be realized, the invention is capable of modifications in various obvious respects, all without departing from the scope and spirit of the invention. Accordingly, the description should be regarded as illustrative in nature and not as restrictive.
Referring to FIGS. 1 and 2. The sports training apparatus 20 comprises a horizontal rectangular base-frame 40 supported by wheels 30, 32 and a main-frame 42 movably mounted on the base-frame 40 about a vertical axis 44. The main-frame 42 has a pair of spaced-apart upright front members 60 and a pair spaced-apart upright rear members 62. The main-frame 42 is supported by a pivot member 46, such as, for example, a pivoting flange, affixed to the base-frame 40, and is movable about the vertical axis 44 by means of a rotating linear actuator 48. The sports training apparatus has an enclosure 26 for protecting the interior components of the sports training apparatus 20 from precipitations, dust and the like, and for safely covering the mechanism when in use.
The main-frame 42 supports a sports ball storage ramp 64 above the ball projecting mechanism 28, the main-frame 42 also provides support for the enclosure 26. The enclosure 26 has an opening 66 in the top surface thereof communicating with an inlet portion 68 of the storage ramp 64 for loading the storage ramp 64 with a plurality of sports balls.
A pair of ball projecting mechanism support members 45 supports a ball support cup assembly 70. The ball projecting mechanism 28 is pivotally mounted between the pair of ball projecting mechanism support members 45 and is movable about a transversal horizontal axis 36. The ball projecting mechanism 28 comprises an arcuate structure 80 having its front end connected to the axis 36 and its rear end connected to a lobbing linear actuator 82. A striking leg member 84 is pivotally connected to the arcuate structure 80, at pivot 86. The striking leg member 84 is operable back and forth by way of a compressible spring and detent rod assembly 88 and a compressing linear actuator 90. The striking leg member 84 has a boot 98 on its lower end for contacting a sports ball 38. The boot 98 has concentric grooves on its striking surface for providing a better grip on the ball. The boot is preferably made of aluminum, and covered with a coating of urethane.
FIGS. 3 a and 3 b show an embodiment of the compressible spring and detent rod assembly 88. The compressible spring and detent rod assembly 88 comprises a pair of springs 150, a pair of detent rods 152 and a latching mechanism 154. The latching of the striking leg member 84 into the cocked position is effected by extending the compressing linear actuator 90 such that the compressing linear actuator 90 pushes the upper portion of the striking leg member 84 causing the striking leg member to rotate around axis 86 to compress the compressible spring and detent rod assembly 88 causing the latching mechanism 154 to progressively latch onto the detents of detent rods 152 according to the desired compression of the springs 150. The arrows in FIG. 4 depict the movement of the members of the ball projecting mechanism 28 moving into a cocked position.
Referring now to FIGS. 8 a and 8 b, shown is another preferred embodiment of the compressible spring and detent assembly 88, including a pair of springs 150 and a pair of rods 152. A front bearing 171 and a rear 172 bearing support the rod 152. The spring member 150 has a front end 173 adapted to receive a bolt and nut system 170 for connecting the two front end portions 173 of the springs 150. A telescoping tube assembly can be disposed in between the two rods 152, the telescope tube including a fixed outer tube member 176 and a slidable inner tube member 175, the inner tube member 175 extending forwardly parallel to the springs 150. The inner tube member 175 has a front end 174 which is adapted to receive the bolt 170 for connection to the springs 152 for simultaneously movement of the inner tube member 175 with the parallel springs 152.
FIG. 9 a is a cross-sectional view of the compressible spring and detent assembly 88 shown in FIG. 8 b along line A-A. The inner tube member 175 is illustrated in a retracted or latched position inside the outer tube member 176 of the telescoping tube assembly.
The latching of the striking leg member 84 into a cocked position is effected by extending the compressing linear actuator 90 such that a front end 178 of the compressing linear actuator 90 pushes the upper portion of the striking leg member 84 causing the striking leg member to rotate around axis 86 to compress the compressible spring and detent assembly 88. During the compression of the spring and detent assembly 88 the rods 150 and the inner tube member 175 move rearward with the inner tube member 175 being retracted inside the outer tube member 176 of the telescoping tube assembly for compressing the springs 152. A latching mechanism includes a series of recesses or detents disposed, preferably, on the upper face of the inner tube member 175, which are used in connection with a sliding latch 177 to progressively retain the inner tube member 175 and the springs 152 at a desired compressed position according to the level of elastic energy to be released. The energy release can be actuated by urging the sliding latch upwardly from the locking position inside the recess or detent through a pulley and cable system including a set of pulleys 179 and a cable 180.
FIG. 9 b shows an exploded region F of FIG. 9 a further illustrating an exemplary embodiment of the locking portion of the sliding latch 177, which includes a bolt 181, a locking sleeve 182, and a locking sleeve spacer 183. The cable 180 is illustrated attached to a flange projecting of the sliding latch 177. As the linear actuator 90 moves rearward it will get to appoint when the end of the cylinder bracket engages the trigger release bracket that holds one end of the cable. Continuing to move rearward, the linear actuator 90 pulls the cable which in turn urges the sliding latch 177 upwardly in order to disengage the locking portion thereof from the recess or detent disposed on the inner telescoping tube 175, and, thus, releasing the elastic energy in the spring 152 and propelling the kicking arm forward to engage the ball for projection as desired.
The plurality of linear actuators in the present invention each has a built-in linear resistor. The linear resistors allow a microcontroller 106 to monitor and control the movement of the plurality of linear actuators to within an accuracy of approximately 1/1000 of an inch (25.4 μm). It will be appreciated that the length that the compressing linear actuator 90 is extended is directly related to the degree of compression on the springs of the compressible spring and detent rod assembly 88, and is directly related to the force with which the ball will be stricken by the striking leg member 84.
The microcontroller 106 is preferably mounted on the upright rear members 62 and above a pair of 12V rechargeable batteries 108 supported on the rear end of the main-frame 42. The rechargeable batteries 108 supply electrical power to the plurality of electronic control and electronic drive systems of the sports training apparatus. The rechargeable batteries 108 are connected in series to provide a total potential of 24V and in a preferred embodiment can be re-charged via an external source, such as, for example, a golf cart charging system.
The sports training apparatus 20 of a preferred embodiment further comprises a solar charging system for charging the rechargeable batteries 108 prolonging the use of the apparatus in a given practice session. The solar charging system comprises at least one solar panel affixed to the outside of the enclosure 26 and is electrically connected to the rechargeable batteries 108 allowing for a constant trickle charge when exposed to external sources of light.
The lobbing linear actuator 82 is mounted between the rechargeable batteries 108 and is connected to the rear end of the arcuate structure 80 for raising and lowering the arcuate structure 80 and for correspondingly lobbing the sports ball 38 with more or less height.
Referring now to FIGS. 5 a to 5 c, there is illustrated therein the ball support cup 130 for supporting a sports ball 38 within the striking path of the striking leg member 84. The sports ball 38 is preferably supported on a concave rubber cup 130 which is affixed to a movable vertical bar 132. The vertical bar is in turn mounted in a drive block 134 which is movably mounted on a horizontal bar 136. The horizontal bar 136 is affixed to the upright front members 60 of the main-frame 42. There are also provided on the slide block 134, a fourth and fifth linear actuator (not shown) for engaging with the horizontal bar 136 and the vertical bar 132 respectively, for moving the slide block 134 and the support cup 130 relative to the main-frame 42.
The adjustment of the sports ball 38 in lateral directions relative to the main-frame 42 is useful for varying the point of impact of the boot 98 against the sports ball 38, to impart a spin and a curving trajectory to the ball. The action of the fourth and fifth linear actuators causes the cup 130 to raise or lower or move to left or right, to optionally impart a combination of a lob trajectory and vertical or horizontal spinning motion to the sports ball being launched by the sports training apparatus 20.
A sports ball storage ramp 64 and control gate 146 are also provided for automatically loading a sports ball on the support cup 130. The storage ramp and control gate are separately illustrated in FIGS. 6 a, 6 b and 7, respectively. The storage ramp 64 has a rectangular helix shape and covers a full turn inside the enclosure 26 of the sports training apparatus 20. The control gate 146 is positioned above the low end of the ramp and is operated by a solenoid actuator 148 to let one ball at a time fall onto the support cup 130.
The operation of the sports training apparatus 20 of a preferred embodiment is primarily controlled by an external remote control (not shown), with secondary controls on the apparatus itself. The external remote control of the apparatus communicates with the microcontroller 106 by means of an electrical cable having a substantial length such that the apparatus is controllable from a distance, in a preferred embodiment the external remote control communicates with the microcontroller 106 via wireless connectivity, such as, for example, Bluetooth™ or Wi-Fi. The external remote control comprises a joystick for changing the trajectory (direction) of the ball, and a plurality of buttons and/or control knobs for modifying various settings having the following, but not limited to, designated functions:
an on/off button for turning the sports training apparatus 20 on or off;
an emergency stop button to power down the sports training apparatus 20;
a reset button to cause all the components of the sports training apparatus 20 to move to an arbitrary rest position;
a load button for loading a ball on the support cup 130;
a pre-load control function for pre-loading the projecting mechanism 28 to any gradient of a maximum force;
a lob function to add more or less lob to the trajectory of the ball;
a spin function to move the support cup 130 laterally and increase or decrease the spin of a ball;
a save ball trajectory function;
a program button to load a saved program; and
a ball launch button to cause the sports training apparatus 20 to launch a sports ball 38; and
a mode of operation function, to operate the sports training apparatus 20 in for example, a Manual, Automatic or pre-Program mode.
