20130074818TOY PROJECTILE LAUNCHER APPARATUS - Several variations of a toy projectile launcher apparatus for discharging EVA balls. The apparatus includes a housing, a barrel portion, a grip portion, a trigger, a ram movable in the housing, a carriage also movable in the housing, a negator spring, handles for cocking the apparatus, and a lever pivotally mounted to a shaft in the housing just behind a ball to be discharged. In operation, a user pulls a handle rearward to move the ram and carriage and extend the spring. Pulling the trigger disengages the ram to impact the lever causing the lever to slap the ball to cause discharge of the ball. The lever and the shaft may be moved from side to side to cause the ball to be discharged straight ahead or curved to the left or right.03-28-2013

20090293853Projectile launching assembly - A simulated gun launches a retrievable projectile in the form of a cylinder containing a compressible spring. The spring is compressed by inserting the barrel of the gun into the bore of the cylinder. A tab on the end of the cylinder rides in a helical groove on the surface of the barrel to cause the projectile to rotate about the axis of the barrel as the projectile is launched.12-03-2009
20120037136BALL MACHINE - A ball machine has a link mechanism. One end of the link mechanism is connected with an elastic member, and another end of the link mechanism is connected with a power unit. The link mechanism is connected with a deformable carrier. Thereby, a ball is placed on the carrier. The power unit drives the link mechanism to operate. The carrier is deformed to a certain degree to release the link mechanism. The elastic unit brings the link mechanism to restore the carrier so as to toss the ball automatically.02-16-2012
20120037135DOUBLE BARREL TOY LAUNCHER APPARATUS - A toy launcher apparatus for discharging soft foam projectiles, the apparatus having a housing and a barrel assembly, including side-by-side barrels, that simulates a real double barrel shotgun. Within the housing are two launching assemblies operatively connected to the barrels, and a trigger assembly for capturing launching tubes of the launching assemblies and for allowing a user to release the launching tubes, and launching springs mounted around the launching tubes to cause the projectiles to be “fired” when the launching tubes are released. Also mounted to the housing and the barrel assembly, and operatively connected to the launching assemblies, is a cocking assembly having an elongated link pivotally connected at one end to the barrel assembly and at an opposite end to a ratchet and compression mechanism. The ratchet and compression mechanism includes a central block with an upward extending arm for engaging the launching tubes to compress the launching springs, and a downward extending arm for engaging a rack connected to an inner frame of the housing to prevent the launching springs, when partially compressed, from snapping to an expanded position should the user fumble the apparatus during a cocking cycle. The barrel assembly is rotatable between a housing aligned position and a housing nonaligned position. The barrel assembly also includes a slide collar for facilitating sliding the barrels between an extended position and a retracted position when the barrel assembly is in the housing aligned position.02-16-2012
20120073554TOY PROJECTILE LAUNCHER APPARATUS - A toy launcher apparatus for discharging circular projectiles, the apparatus having a housing, lower and upper panels mounted to the housing, supports mounted to the housing, a cocking slide and a slide spring connected to the supports, a projectile receptacle connected to the cocking slide, release levers mounted to the housing, a guide wall mounted to the lower panel, a positioning wheel also mounted to the lower panel, and a trigger mounted to the housing. The lower panel includes a slot positioned parallel to the guide wall but off center relative to a center point of a load projectile. Beneath the lower panel is a rotatable launch arm connected to a torsion spring and a catch structure. The upper and lower panels are parallel to one another and spaced to receive a projectile. The projectile is loaded into the projectile receptacle when the receptacle is exposed during the time the launch arm and torsion spring are cocked by a user pulling rearward on the cocking slide. The launch arm is captured by the catch structure, and the cocking slide and the receptacle are also captured. After loading the projectile, the one of the release levers is activated to snap the cocking slide, the carriage and the loaded projectile to a predetermined launch position. When a user pulls the trigger the launch arm is rapidly rotated by the torsion spring through the slot where the launch arm impacts the loaded and correctly positioned projectile and causes the projectile to be discharge with a spin.03-29-2012
20120266852Toy Hand Grenade - A toy hand grenade has a plurality of bores which receive soft darts. A launcher is received in each bore and is spring loaded. An actuator retains the launchers in a spring-loaded, unactuated position. The actuator is displaceable relative to the body to release the launchers and substantially concurrently eject the darts from the hand grenade. A pin or a clip may be employed to lock the actuator in a locked position.10-25-2012
20120266853Toy Hand Grenade with Timer Mechanism - A toy hand grenade has a plurality of bores which receive soft darts. A launcher is received in each bore and is spring loaded. An actuator retains the launchers in a spring-loaded, unactuated position. The actuator is displaceable relative to the body to release the launchers and substantially concurrently eject the darts from the hand grenade. A pin or a clip may be employed to lock the actuator in a locked position. A timer is employed to delay actuation of the actuator to release the launchers and eject the darts from the hand grenade. A sandbag ring is imposed to ensure proper orientation and stability of the hand grenade for the timer actuated feature.10-25-2012
20110226225Biased Releasable Connection System - The present invention is directed to providing a biased releasable connection system that is compact, lightweight, inexpensive and low-power. The system comprises a releasable object that is biased against a retaining mechanism until the connection is released. The system further comprises a small and lightweight shape memory alloy member to actuate the release of the connection. When the connection is released, the biasing mechanism propels the releasable object in a particular direction. The compact design of the system is partly attributable to the strategic utilization and positioning of the shape memory member within the system.09-22-2011
20120080019TOY PROJECTILE LAUNCHER APPARATUS - A toy projectile launcher apparatus for discharging balls. The apparatus includes a base, a ram movable in the base, a carriage also movable in the base, a negator spring, a handle for cocking the apparatus, a lever pivotally mounted in the base just behind a ball to be discharged and a trigger. In operation a user pulls the handle rearward to cock the apparatus and a catch engages the ram. The carriage is attached to the spring and extends the spring when the carriage and the ram move rearward. The user pulls the trigger to release the ram and the carriage.

The apparatus includes a housing, a ram movable in the housing, a carriage also movable in the housing, a negator spring, a handle for cocking the apparatus, and a lever pivotally mounted in the housing just behind a ball to be discharged. In operation, a user pulls the handle rearward and a connector engages the ram to pull the ram rearward. The ram abuts the carriage and when the ram moves rearward the carriage also moves rearward. The carriage is attached to the spring and extends the spring when the carriage moves rearward. At a predetermined location the connector disengages the ram.04-05-2012
20130092138PINATA DEVICE - A piñata device includes a main body housing an open-top container that may be filled with candy, toys, or other items. The open-top container is spring loaded using and arrangement of elastomeric bands and a locking mechanism which, when triggered, releases the open-top container, thereby causing the container to immediately accelerate towards an opening on the main body and launch the items outwards of the main body and onto the floor for collecting by the participants. In a preferred embodiment, the locking mechanism is triggered by hitting a target with a ball. After use, the container may be pushed or pulled back into a loaded position for reuse.04-18-2013
