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.

The projectile launcher includes a riser base, an elongate barrel assembly attached to the riser base, a crank mechanism attached to the back of the barrel assembly, a trigger assembly, and an internal bow assembly mounted to the riser base. The crank assembly includes a rotatable crank for selective reciprocation of a cocking carriage riding inside a rail system in the barrel assembly. The cocking carriage selectively engages a projectile nock carriage riding within the rail system to push the nock carriage into a cocked position. The internal bow assembly includes vertically spaced upper and lower resilient bow arms and a system of pulleys and cables interconnecting the bow arms and the nock carriage. Cocking to the nock carriage flexes the bow arms in preparation for placement and firing of a projectile. The working components of the projectile launcher are enclosed by a covering to protect the user.

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.

A dart game system that includes: a dart projecting pistol; a dart; a string attached to one end of the dart; a spool, where the spool stores the string prior to launching the dart towards a target; and a bracket that secures the spool to the dart projecting pistol. The pistol may include a barrel, a spring within the barrel, a hammer, a trigger, a trigger guard and a grip. Preferably, the target is a game board, where the game board includes a plurality of spaces representing aspects of a dart game. The plurality of spaces may include a number or a letter designated on each space.

An elastic rubber band launching toy gun that uses a new method to launches six elastic bands in rapid succession using a simple assembly of only six individual parts, and featuring an moving exterior slide in order to mimic the action on a real hand gun. The embodiments of this invention do not rely on any mechanism to return the trigger element to a firing position other than the elastic projectiles fired from the device.

An elastic rubber band launching toy gun that uses a new method to launches 24 elastic bands in rapid succession using a simple assembly of only 13 individual parts, and featuring an optional, adjustable, sliding shoulder support stock. It is designed to resemble a Heckler & Koch MP5 firearm, as manufactured by Heckler & Koch GmbH of Oberndorf am Neckar, Germany. The rubber band gun includes a slideable, lockable stock which can be slid and locked into multiple lengths away from the butt of the firearm.

A scalable flat in-plane-motion mechanical spring device. The device sincludes a frame with one or more flexures attached to the frame on a first end of the one or more flexures. The device further includes a shuttle with one or more of the one or more flexures attached to the shuttle on a second end of the one or more flexures. The frame, the shuttle, and the one or more flexures may be formed as a single piece.

A speargun having ratchet mounted to or integrated into the stock of the speargun to aids in the stretching of the elastic bands to load the speargun. The ratchet is connected to the elastic bands and allows a user to stretch the elastic bands to load the speargun incrementally instead of all at once. The ability to incrementally load the power using a ratchet not only makes it easier to load the speargun, but also enables the same speargun to be used for a variety of spearfishing applications where different amounts of force are optimal to propel the spear.

A toy configured to operate in two modes of operation wherein projectiles are launched from different portions of the toy depending upon which mode of operation the toy is in, the toy having: a housing with a forward pistol grip portion and a rearward pistol grip portion, the rearward pistol grip portion being movably mounted to the housing for movement between a first position to a second position; a mode selector switch movably mounted to the housing for movement from a first position to a second position; wherein movement of the rearward pistol grip portion between the first position and the second position launches a projectile from one portion of the toy when the mode selector switch is in the first position; and wherein movement of the rearward pistol grip portion between the first position and the second position launches a projectile from another portion of the toy when the mode selector switch is in the second position.
