Provided herein is a string shooting device having a string capable of generating lift when propelled from the string shooting device and a guide to readily attach and detach the string from the string shooting device. A string shooting device described herein includes: a body; a housing attached to the body; a pair of wheels, where at least one of the pair of wheels is a driven wheel; and a string, where the string includes a surface texture configured to increase air friction in response to the string being propelled through the air by the pair of wheels. The string of an example embodiment defines an axis along which the string extends, and where the string includes a plurality of fibers extending away from the axis.

Improved pitching machines capable of providing accurate, repeatable, and various pitches for training or simulation purposes (e.g., batting and catching). The pitching machine of the present invention may be operable to deliver pitches that each have a different predetermined trajectory, location, velocity (speed to target), and rotational velocity with repeatable precision and accuracy. Additionally, the pitching machine may be programmable and capable of simulating a pitch sequence, as thrown by a pitcher in a game situation, which provides a novel and effective tool for training batters.

A flywheel-driven setting device for driving fastening elements into a foundation is disclosed, having a driving element, which can be driven in a setting direction by a flywheel and which is guided between the flywheel, which is rotatable about a flywheel rotation axis, and a counter roller, which is rotatable about a counter roller rotation axis. The flywheel rotation axis is arranged at an angle alpha () to the counter roller rotation axis, wherein the angle is not equal to zero.

A toy launcher for toy projectiles includes a drum having two concentric rings of holders with an angular offset between adjacent concentric rings, and motorized flywheels to launch the projectiles. The launcher also includes an assembly for pushing projectiles in the drum toward the flywheels for launch, including a separate pushing rod for each of the concentric rings to advance one projectile at a time toward the flywheels. Both pushing rods are simultaneously pushed when a trigger is pressed, but only one projectile at a time is launched because while one pushing rod advances a projectile, the other pushing rod is blocked by a structure on the drum. Successive presses of the trigger cause projectiles to be launched in an alternating sequence in which one projectile at a time is launched first from a first concentric ring, then from a second concentric ring, then from the first concentric ring.

A sport carrying bag has a rotatable disc which is configured with a plurality of circumferentially spaced ball-receiving regions including one through-hole region, a mounting plate located below the disc, a chute downwardly extending to a loading section of launching apparatus, a fixed bi-directional ball feeding motor for rotatably driving the disc, and a controller in data communication with the ball feeding motor. Upon rotation of the disc in a first direction, a ball received in the through-hole region ceases to be contacted by the mounting plate and gravitates through the chute to the loading section of the launching apparatus. In response to a detected jammed condition, the controller commands the ball feeding motor to reverse its operating direction such that the disc will rotate in a second direction to cause one or more jammed balls to become dislodged.

The present invention is a toy projectile and launcher system. The lightweight projectile has an exterior surface symmetrically disposed about an imaginary longitudinal axis. The launcher has a holding cavity composed of three semi-flexible sides, two of which sides apply counter-acting forces to the surface of the projectile along the imaginary longitudinal axis. The launcher has a mechanism for applying a motive force perpendicular to the counter-acting force vectors and perpendicular to the projectile's imaginary longitudinal axis. When the motive force is applied to the projectile, the semi-flexible sides deform and return to pre-deformation positions, thereby launching the projectile into flight.
