The invention relates to an archery system that launches an arrow from a position that is perpendicular to a direction of flight for the arrow. After release, the arrow rotates to a position that is parallel to the direction of flight to the target.

The invention uses a propulsion mechanism in the form of electromagnetic force by current flowing through conductive material, a loaded spring or compressed air to expel a string attached to a strong adhesive, removable surface. An edge attached material allows the adhesive to be fired through a barrel onto surfaces it will adhere to and allow the user to pull on objects from a distance.

A robotic vehicle is provided with vertical ball cannon and a ball deflector. The ball deflector is mounted over the vertical ball cannon on a vertical linear slide. The deflector redirects a ball shot from the cannon toward a desired target, such as a cylindrical goal. The vehicle further includes a rotating goal-grabber for anchoring a goal adjacent to the vehicle and underneath the output of the deflector. A pair of counter-rotating helical screws capture a ball from the ground and raise it into the ball cannon. The cannon launches the ball toward the deflector, which redirects the ball's upward vertical motion away from the cannon into a downward vertical motion toward the desired target.

The speargun for underwater fishing comprises a spear, a hollow hand grip having therewithin a retaining mechanism for retaining the spear, a snap trigger of the retaining mechanism for the release of the spear, a hollow barrel fixed to the hand grip, a terminal head fixed to the barrel and supporting at least one lateral pulley on which a rubber band for the propulsive thrust of the spear is wound, and a housing for engaging one end of the rubber band, formed in a single piece with a wall of the hand grip and located in a transversal geometric plane of the speargun which includes the axis of the barrel and cuts the speargun into an upper half-part and a lower half-part.

Provided is a connector for a toy gun having a feature for detecting whether or not a projectile remains. The connector includes a connector body coupled to the toy gun to be connected with an upper portion of a magazine when the magazine is inserted into the toy gun, a hole formed to pass through front end of the connector body and configured to accommodate the projectile provided by the magazine, a projectile fixing portion positioned on the connector body in which the hole is formed to fix the projectile provided via the hole, a projectile sensing portion which senses whether or not a projectile remains in the hole; and a first protrusion interlocked with the projectile sensing portion to control movement of a cylinder of the toy gun depending on whether or not a projectile remains in the hole.

A versatile hunting bow with a circular rotatable handle mounted on a circular frame of the riser of the bow. The riser is skeletonized and has an asymmetrical shape. The archers can rotate and adjust the orientation of the handle to their natural wrist position. The outer wall of the circular handle has a series of parallel thread cuts that match with the thread cuts on the inner wall of the circular frame of the riser. Two limbs are connected and secured to the riser through limb bolts. When limb bolts are tightened, the geometry of the riser and the arrangement of the limbs create tensions that slightly distort the shape of the riser. The distortion prevents the thread cuts from moving along each other. Thus, the handle is no longer able to rotate when the limb bolts are tightened and the handle is locked.

An arming assembly for a personal self-defense device includes a substantially closed-ended cylindrical member having a first end and a second end, the cylindrical member having an interior chamber. At least one opening being formed within the first end for the inserting and exiting of a porcupine quill. A translatable piston includes a spring and a disc being disposed within the interior chamber. At least one arm being attached to the spring in order to compress and release the spring and translate the disc toward the second end. At least one quill is inserted into the opening formed within the first end and sits in an associated indentation formed within the disc. Once the arm is released, the quill is projected forward and exits through the opening formed within the first end, which is aimed at a would-be attacker. The arming assembly may be double-acting by having conjoined opposed similar components.
