## Background
BACKGROUND OF INVENTION
The present invention generally relates to baseball pitching machines. More specifically, the present invention relates to pitching machines for simulating a soft toss pitch from a coach.
There are many pitching machines on the market. Most of the pitching machines are designed to simulate a pitcher delivering a pitch from a pitcher”s mound to a live hitter at Home Plate. Soft toss pitches are commonly used as a baseball hitting drill to improve a hitter's hand/eye coordination, timing, and bat speed. This drill is used by coaches and players from Little League on up to the Major Leagues. Normally, a coach kneels to the side of the hitter, just outside the strike zone, and underhand-tosses a ball into the strike zone where the hitter hits it. There are a few Soft-Toss devices on the market, however they lack certain features to simulate a coach tossing the baseball. For example, one device may toss a ball into the air, but the machine is designed to use light-weight balls, as a toy and does not use real baseballs. Another machine may toss baseballs, but the ball height or angle cannot be adjusted. In addition, most of these machines use battery or electrical power to run motors, which are timed. They toss a ball every five or six seconds, which does not allow for a pause for instruction unless the machine is turned off. With a timed, motorized machine, the hitter or coach must turn off the machine each time to talk. Last, most coaches will tell a hitter to shift his weight back before the swing. Current machines have no provisions to correct or improve this skill. What is needed is a soft toss pitching machine which is user friendly and provides the same flexibility as having a coach toss the baseball.
It is an object of the present invention to provide soft toss pitching machine which is user friendly and provides the same flexibility as having a coach toss the baseball.

DETAILED DESCRIPTION
The present invention is a soft toss pitching machine, as shown in FIGS. 1-14. The soft toss pitching machine allows one person to practice hitting baseballs without requiring any battery or electrical power. The hitter pushes down on a pedal with the hitter”s forward foot. A ball is then launched into the hitter”s strike zone, where the hitter swings at the launched ball. The soft toss pitching machine allows the hitter to control when the hitter gets a ball pitched to the hitter. Because soft-toss is a practice drill, often a coach will be present to offer guidance and instruction. With the soft toss pitching machine, the hitter has full control of when the next ball will be launched without having to turn anything off. The height and angle of the ball can be adjusted, which allows for pitches to be thrown anywhere from high or low inside to high or low outside the strike zone. The soft toss pitching machine allows for proper positioning so that the hitter shifts his weight back before swinging. The soft toss pitching machine uses real baseballs or softballs. Using real balls allows a hitter to know the hitter is swinging properly, or if the hitter is not making solid contact with the ball. The soft toss pitching machine allows a coach to stand back and observe while the hitter swings. Often-when there is one hitter and one coach, the coach is tossing balls and cannot see the swing dynamics of the hitter.
FIG. 1 show the soft toss pitching machine 10, which includes a support frame 12, ball tube assembly 14, ball release assembly 16, ball firing assembly 18 and a foot pedal assembly 20. The support frame 12 includes two front legs 22, two rear legs 24, two lower cross members 26 and an attachment cross member 28, as shown in FIGS. 1-2.

The pedal 174 is attached to the pedal end 178 of the pedal arm 172. The release cable guide 102 and the firing cable guide 158 each have a second end 180 connected to the base of the foot pedal assembly 20. The release cable 76 has a second end 182 extending from the second end 180 of the release cable guide 102 and connected to the cable end 176 of the pedal arm 172. The firing cable 118 has a second end 184 extending from the second end 180 of the firing cable guide 118 and connected to the cable end 176 of the pedal arm 172. The pedal arm 172 includes a firing cable pedal guide 186 as part of the pedal arm 172. The firing cable pedal guide 186 acts as a fulcrum which applies more pulling pressure on the firing cable 118 during movement of the pedal arm 172. The pedal arm 172 includes an adjustable pedal stop 188 on the bottom of the pedal end 178 of the pedal arm 172. The adjustable pedal stop 188 screws in and out of the bottom of the pedal arm 172.
The soft toss pitching machine 10 is operated as follows and as shown in FIGS. 11-14. A ball 190 is loaded into the firing cup 120 at the ball rest end 66 of the firing section 60 of the ball tube assembly 14. Balls are loaded into the open storage area 62 of the loading section 54. The balls will roll down the inner open path into the release section 56, whereby the first loaded ball 192 into the open storage area 62 will stop at the first ball stop 86 of the release arm 74. The first loaded ball 192 into the open storage area 62 is considered the second ball 192. Balls will continue to stack up until the open storage area 62 of the loading section 54 is full. The hitter positions himself in front of the soft toss pitching machine 10 and uses the forward foot to push down on the pedal 0.174, which pushes down the pedal end 178 of the pedal arm 172. The pedal arm 172 simultaneously pulls on the release cable 76 and the firing cable 118. Pulling on the release cable 76 at the second end 180 causes the first end 106 of the, release cable 76 to pull and rotate the release arm 74, such that the first ball stop 86 exits from the inner open path, as shown in FIG. 11. When the first ball stop 86 exits from the inner open path, the second ball 192 rolls down and engages the second ball stop 88 of the release arm 74 that has rotated into the inner open path. At the same time, pulling on the firing cable 118 at the second end 184 causes the first end 150 of the firing cable 118 to pull the firing rod 114 downward. Pulling of the firing rod 114 downward, pulls down the firing cup 120 and compresses the firing spring 116 in the firing housing 68. The firing rod end 126 of the activation arm 110 is shown as a flat piece inserted in the firing rod end slot 134. This allows the activation arm 110 to pivot up and down at the firing rod end slot 134. When the firing rod 114 is pulled down, the firing rod 114 and firing rod end 126 of the activation arm 110 bind together. The firing rod 114 and firing rod end 126 of the activation arm 110 bind together due to the frictional forces between front and rear surfaces 194 of the square firing rod 114 that engage front and rear surfaces 196 outlining the square hole 130 of the firing rod end 126. The front and rear surfaces 194 of the firing rod 114 engage the front and rear surfaces 196 outlining the square hole 130 of the firing rod end 126 due to the activation arm 110 being pulled at an angle to the firing rod 114 by the activation return spring 112. The binding of the firing rod 114 and firing rod end 126 of the activation arm 110 holds the compressed firing spring 116 and firing cup 120 in a lowered position. The firing cable pedal guide 186 on the pedal arm 172 lowers the amount of pressure which is needed to be applied by the hitter to pull down the firing rod 114 and compress the firing spring 116.
When the hitter releases the pedal 174, the firing spring 116 remains compressed due to binding between on the firing rod 114 and firing rod end 126 of the activation arm 110. Also, when the hitter releases the pedal 174, the release arm spring 80 biases the release arm 74 to rotate such that the second ball stop 88 exits from the inner open path and the first ball stop 86 enters the inner open path. When the second ball stop 88 exits the inner open path, the second ball 192 falls down the remaining portion of the release section 56 and into the activation section 58 of the ball tube assembly 14 along the inner open path. At the same time, the first ball stop 86 engages the next ball (not shown) above the second ball 192 and prevents the next ball from moving beyond the first ball stop 86. The second ball 192 falls downward toward the top end 162 of the activation rod 108. There is a time delay created due to the falling of the second ball 192 toward the top end 162 of the activation rod 108. This time delay is dependant on the distance from the second ball stop 88 to the top end 162 of the activation rod 108. Once the second ball 192 hits the top end 162 of the activation rod 108, the activation rod 108 is forced downward and the second ball 192 rolls past the top end 162 of the activation rod 108 and onto the firing section 60 along the inner open path. Movement of the activation rod 108 downward forces the activation end 128 of the activation arm 110 downward. Movement of the activation end 128 of the activation arm 110 downward releases the binding forces between the firing rod 114 and firing rod end 126 of the activation arm 110 and releases the firing rod 114. Release of the firing rod 114 allows the firing spring 116 to force the firing cup 120 upward and launch the first ball 190 in the firing cup 120 up into the air for the hitter to swing and try to hit the launched ball. After this, the activation return spring 112 pulls the activation end 128 of the activation arm 110 upward. Movement of the activation arm 110 upward, forces the activation rod 108 to rise and the top end 162 of the activation rod 108 to protrude into the activation section 58. Thereby, finalizing a reset of the soft toss pitching machine 10. The second ball 19.2 rolls into the firing cup 120 and the next ball that was above the second ball 192 is ready to be release the next time the hitter depresses the pedal 174.
The angle that a ball is launched by the firing cup 120 can be set by raising or lowering the firing section 60 of the ball tube assembly 14. The firing section 60 of the ball tube assembly 14 is raised or lowered by rotating the ball tube assembly 14 about the first point of connection of the ball tube assembly 14 to the support frame 12. The ball tube assembly 14 is unsecured or secured in position by use of the adjustment knob 52 with the threaded stud 50 and the adjustment brace 42. The height a ball is launch can be adjusted by increasing or decreasing the depth of depression of pedal 174 of the foot pedal assembly 20. This allows for the soft toss pitching machine 10 to simulate high or low inside to high or low outside pitches in the strike zone. The adjustment of the depth of depression of the pedal 174 is controlled by the adjustable pedal stop 188 on the bottom of the pedal end 178 of the pedal arm 172. Some hitters, especially young hitters, get into a habit of lunging forward when swinging a bat. This habit reduces power in the swing. Coaches will tell their hitters to shift the weight back and be light on the hitter”s front foot. The soft toss pitching machine 10 encourages the hitter to do this because the hitter has to shift the hitter”s weight back as the hitter returns to a hitting position from pressing the pedal 174 with the hitter”s front foot. The release cable spring 78 allows for self adjustment of the length of the release cable 76 based on the adjustment of the adjustable pedal stop 188. The rounded shape of the first ball stop 86 and the second ball stop 88 aids in promoting the naturally rolling of a ball along the inner open path. Finally, the ball tube assembly 14 includes access holes 198 along the ball tube assembly 14 to allow assembly and maintenance of the soft toss pitching machine 10.
While different embodiments of the invention have been described in detail herein, it will be appreciated by those skilled in the art that various modifications and alternatives to the embodiments could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements are illustrative only and are not limiting as to the scope of the invention that is to be given the full breadth of any and all equivalents thereof.
