DETAILED DESCRIPTION OF THE DRAWINGS

[0032] For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.

[0033] A slow pitch softball pitching machine 10, shown in FIG. 1, is configured to discharge softballs 11 along an arcuate path similar to the path taken by a softball that is slow pitched by a human pitcher as suggested in FIG. 6. The machine 10 includes a base 12, a ball ramp assembly 14, and a ball launcher 16. The base 12 has legs 21, 22 that support the ball launcher 16 at a preset height selected to mimic the discharge height of a human pitcher lobbing a softball pitch. The ball ramp assembly 14 stores and presents softballs 11 to be discharged from the machine 10 by the ball launcher 16.

[0034] The base 12 has legs 21, 22 that move from an expanded configuration, shown in FIG. 15, to a collapsed configuration shown in FIG. 18. In the expanded configuration, the legs 21, 22 extend downwardly from an underside of the ball launcher 16 to enable use of the pitching machine 10. In the collapsed configuration, the legs 21, 22 extend along the underside of the ball launcher 16 for transport and storage of the pitching machine 10.

[0035] In the illustrated embodiment, rear leg 21 is pivotably coupled at a proximal end to an aft side of the ball launcher 16. The rear leg 21 also has a free distal end that engages the ground underlying the machine 10 in the expanded configuration and that provides a handle that extends away from the ball launcher to provide a handle when the base is in the collapsed configuration. The length of the rear leg 21 can be adjusted using pinned connection 25 that controls telescoping of rear leg foot 23 as suggested in FIGS. 1-3.

[0036] The front leg 22 is pivotably coupled near a mid-point of to the rear leg 21. The front leg 22 has a first end that engages a catch at the front of the ball launcher 16 when the legs 21, 22 are in the expanded configuration. The front leg 22 also has a second end fitted illustratively with a wheel 24 for rolling support of the machine 10 in the collapsed configuration and a wheel stop 26 that can be positioned in an anchored position to fix the front leg 22 when in the expanded configuration.

[0037] The ball ramp assembly 14 includes a hopper 30, a ball rail 32, and a ball gate 34 as shown in FIG. 2. The hopper 30 stores softballs to be presented to the ball launcher 16. The ball rail 32 holds a single softball 11 in position for a throwing arm 52 of the ball launcher 16 to scoop the softball 11 and lob it to a waiting batter. The ball gate 34 selectively allows balls 11 from the hopper 30 to move onto the ball rail 32. In illustrative embodiments, the ball gate 34 can be remotely controlled, controlled on a timer, controlled based on throwing arm 52 position, or otherwise opened as needed to allow softballs 11 to be fed one at a time onto the ball rail 32. In other embodiments, the ball gate 34 can be provided by a wheel that selectively engages and moves balls at the exit of the hopper to push them onto the rail 32.

[0038] The hopper 30 includes a ball-storage bin 36, a lid 38, and a transfer tube 40 as shown in FIG. 10. The ball-storage bin 36 is shaped to define pre-set travel lanes via ribs 35 through the hopper 30 so as to guide balls in sequence to the ball gate 34. The lid 38 is coupled to the ball-storage bin 36 to allow for selective access into the bin 36. The transfer tube 40 carries balls 11 from an end of the pre-set travel lane at the bottom of the ball-storage bin 36, under a housing 50 of the ball launcher 16 toward the ball rail 32.

[0039] The ball rail 32 illustratively includes a mount bracket 44 and a pair of ball support rods 41, 42 as shown in FIG. 11. The mount bracket 44 is pivotably mounted to the housing 50 of the ball launcher 16 and has a bracket lock 46 provided by a retractable plunger configured to selectively retain the mount bracket 44 (and support rods 41, 42) in a desired position. The ball support rods 41, 42 are bent to locate via gravity a ball 11 loaded onto the ball rail 32 for pitching by the throwing arm 52.

[0040] The ball gate 34 is mounted at the end of the transfer tube 40 included in the hopper 30 and moves to block or allow a softball 11 to exit the hopper 30 as suggested in FIG. 1. The ball gate 34 may move from a normally deactivated (closed position) to an activated (opened position) by control signal from on-board controls, remote controls, or timed controls.

[0041] The ball launcher 16 includes a housing 50 containing a drive mechanism 54 as well as a throwing arm 52 arranged outside the housing 50 as shown in FIGS. 1-5. The throwing arm 52 launches a softball 11 off of the ball rail 32. The drive mechanism 54 moves the throwing arm 52 along an arc to drive launch of the softball 11.

[0042] The housing 50 protects the drive mechanism 54 and supports various user inputs/outputs as suggested in FIGS. 4-5. More specifically, the housing includes indicator lights 56 mounted to the front of the housing 50 so as to alert a batter of an upcoming pitch. The housing 50 also includes user inputs 58 for controlling operation of the ball launcher 16 as shown in FIGS. 5 and 12. The user inputs 58 illustratively include a three position off/auto/manual switch, and a pitch strength dial. The housing 50 also has connection points for a battery charger and a remote user input.

[0043] Remote user inputs can be in the form of a home-plate remote user input 60 or pedal remote 62 adapted for communication with the ball launcher via wired or wireless communication as shown in FIGS. 13 and 14. The home-plate remote user input 60 is shaped to lie over (or in place of) a home plate and has sensors configured to detect a bat tap or step onto the plate for initiating a ball launch sequence. The pedal remote 62 is configured to detect a bat tap or step onto the pedal for initiating a ball launch sequence;

[0044] The throwing arm 52 has an extension 64 that extends from the drive mechanism 54 and a molded hand 66 shaped to impart forward spin on a ball upon discharge from the machine as shown in FIG. 1. In illustrative embodiments, the throwing arm may have a bent metallic extension 64A and a molded hand 66A as shown in FIG. 7. According to another embodiment, the throwing arm 52 may have an integrally molded extension 64B and a hand 66B as shown in FIG. 8. In yet another embodiment, the throwing arm 52 may have a round tube extension 64C and a stamped metallic hand 66C as shown in FIG. 9.

[0045] Turning now to the drive mechanism 54, one specific implementation of a powered drive for moving the throwing arm 52 along the pitching arc is shown in the various views of FIG. 19. In this implementation, the drive mechanism 54 includes a battery 70, a motor 72, and control electronics 74 in a housing with a transformer element. The battery 70 stores on board power. The motor 72 is coupled to the battery via the control electronics 74 and drives a chain sprocket 76 coupled to the throwing arm 52.

[0046] A spring mechanism 78 is also coupled to the throwing arm 52 to control forward motion of the throwing arm 52 and to return the throwing arm 52 to its starting position. More specifically, the spring mechanism 78 cooperates with a chain and cam assembly (not shown) between the motor 72 and the pitching arm with the spring 78 acting as the force component. The motor/chain/cam rotates loads the spring 78. The energy of the spring 78 is released when the cam reaches a particular point in the rotation. This process repeats automatically in auto mode and in manual mode, the cam (and arm) are returned to starting position prior to each activation.

[0047] While the disclosure has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as exemplary and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
