  • Patent number: 10843055
    Abstract: The indoor basketball game system includes a multi-paneled folding backboard with a basketball hoop disposed on it. A winged ball deflector is disposed on the ground adjacent the bottom of the backboard and inclined upwards on the board from the bottom edge to form a ball return feature. The ball return feature of the present system via the deflector allows repeated shooting without worrying about chasing down the ball after every shot. Folding side panels of the backboard pivot to provide blocking sides and stability to the backboard, and can be angled to allow the player to shoot from many different positions. The backboard and deflector can be collapsed for storage and transport.

  • Patent number: 9683807
    Abstract: A toy projectile and launcher system. The projectile is tubular in shape and lightweight. The projectile has an exterior surface that is symmetrically disposed about an imaginary longitudinal axis. The launcher has a holding trough that receives and holds the tubular projectile. Within the launcher is a spring loaded element. The spring loaded element selectively moves between a cocked position and a released position. The spring loaded element contacts the projectile in the holding trough as the spring loaded element moves from its cocked position to its released position. Contact with the spring loaded element causes the tubular projectile to launch into flight in a direction perpendicular to its longitudinal axis. Simultaneously, contact with the spring loaded element imparts a spinning rotation to the projectile, wherein the projectile spins about its longitudinal axis in flight. The spinning creates a Magnus effect on the projectile.

    Abstract: A football launcher and the method of using same, such that a player can practice receiving a hiked football without the need of another player being present. The football launcher has two triangular base members that support a mounting shaft between them. A pivot arm is rotatably mounted on the mounting shaft by means of an annular sleeve affixed to a point off center on the underside of the pivot arm. There is a fixed collar on each side of the sleeve to maintain the sleeve and therewith the pivot arm in a centered position on the mounting shaft. A football cradle is attached to the long end of the pivot arm and a step plate is attached to the short end. The football cradle is shaped to hold the football and release it in a straight line when the football launcher is activated. Activation is accomplished when the user steps on the step plate causing the football to be propelled in a low arc straight toward the user.

  • Patent number: 6715478
    Abstract: A ball pitching machine utilizes a leaf spring coupled by linkage to a ball pitching arm. The flexion of the spring can be adjusted by varying the time of operation of a motor driven spring flexion assembly. Upon the selectable spring flexion being achieved, the user then energizes a ball pitching arm for rotation of the arm through a rest position, a ball pick up position and then to a ball release position. During arm rotation, the arm is first coupled to the spring by a linkage assembly such that further rotation of the arm causes the stored energy in the spring to be released to the arm at a position to effect the ball trajectory. The ball trajectory compensates for the various ball speeds so that the ball penetrates the batter's strike zone. This energy transfer accelerates rotation of the arm to a ball release position, the speed of the ball, as perceived by the batter, corresponding in part to the spring flexion and/or ball trajectory as selected by the user.

  • Patent number: 6616555
    Abstract: In an athletic ball server, a collapsible tripod supports an elongated inclined tray containing a linear array of balls. A gate at the low end of the tray cyclically releases balls one at a time from the array to gravity. One edge of a trampoline is pivoted on the tripod. The central portion of the trampoline is aligned to bounce a ball released from the tray. An eye-bolt is connected between the tripod and the trampoline allowing the angular position of the trampoline to be varied. By adjusting the eye-bolt, it is possible to achieve any desired trajectory of the bounced ball from a pop-up or slow pitch trajectory to a ground ball trajectory.

  • Patent number: 6505617
    Abstract: A ball pitching machine of the windmill type simulates the pitching motion of a human pitcher. The machine includes: (a) a rotating plate which rotates vertically 360° at a constant speed about an axis; (b) a pitching arm having a ball holder at a distal end and being pivotably connected to the rotating plate at a proximate end, the pitching arm adapted to rotate vertically about an arc of between about 100 and 300° at a high speed and to rotate about the remaining arc at the speed of the rotating plate; and (c) a flip lever pivotably connected to the pitching arm.

  • Patent number: 6343597
    Abstract: A toy catapult includes a frame and an elongate arm. One end of the arm includes a wheel that is rotatable on an axis defined by a bar of the frame. The other end of the arm includes a ball holder. An aim-protection member is also circumferentially attached to the aim near its middle. The frame includes dual block members, each having a post member extending vertically from it, and a stop member positioned between the post members. Interposing the block members is a lever arm with a wheel-engagement member for holding the arm in tensed, or cocked position. Tension is caused by a flexible bias member which attaches to the arm and to a hook positioned on the frame and located forward of the wheel.

  • Patent number: 6182648
    Abstract: A portable tennis net post-supported tennis ball-throwing device including an elongated support member with a U-shaped clamp for attaching the support member in an upright orientation to an upright tennis net support post. An elongated rigid throwing rod is pivotally connected at one end portion thereof to the support member by a pivotal connection therebetween. An elongated elastic actuator member is connected to and extends between the support member and the throwing rod at respective positions on the support member and the throwing rod spaced from the pivotal connection. A tennis ball holding member is connected adjacent a distal end of the throwing rod and opens toward the support member to receive a tennis ball placed therein. A resilient stop member is connected to the support member to make contact with the throwing rod as it accelerates toward a final position thereof by the stretched actuator member.

  • Patent number: 6129076
    Abstract: A throwing apparatus and method (10) having a base (12), an arm axle mount (14), a throwing arm (16), a release handle (18), and a power section (20). Throwing arm (16) is rotatably connected by means of axle (46) near the bottom (28) of throwing arm (16) to arm axle mount (14). Arm axle mount (14) is located near the front (22) of base (12). The bottom (28) of throwing arm (16) is connected to one end (48) of power section (20). The other end (50) of power section (20) is connected to one of a number of speed adjustment connection locations (52) in base (12). Release handle (18) is movably connected near the back (24) of base (12) and includes release block (62). When the top (26) of throwing arm (16) is pulled in the rearward position towards the back (24) of base (12), release block (62) is pressed by release handle (18) over the top (26) of throwing arm (16) thereby holding throwing arm (16) in the rearward cocked position. An object to be thrown (78) is placed in the "V" shaped form of throwing arm (16).
