Abstract: A projectile launcher using a self-resetting trigger system includes a striker, a sear, and a trigger. The striker, also known as hammer, includes an anchoring notch and is able to slide between a firing position and a ready-for-firing position for launching an object. The sear, which is substantially L-shaped sear, has a first sear end and a second sear end wherein the sear maintains the striker to the ready-for-firing position when the first sear end engages with the anchoring notch of the striker. The trigger, which is capable of self resetting independent from the movement of the striker, contains an elastic lip with a ramp and is able to maintain the sear in a ready position when the elastic lip and the second sear end are coupled in a lock position.

Abstract: A slot car comprises a chassis (110), a motor mounted on the chassis (110) for driving the slot car and a plurality of conductive elements (101, 102) exposed on the chassis (110) which is electrically connected to the motor for driving the slot car. The slot car further comprises a cover (100) covering at least a portion of the conductive elements (101, 102) and which is adapted to restrict the conductive elements (101, 102) from bending and dislocating. The conductive elements (101, 102) may be in form of metal brush (101, 102). The cover (100) is formed with a slanted surface so that the angle between the chassis (110) and the conducting elements (101, 102) does not exceed 7 degree and is further provided with guide members (106, 107). Such guide members (106, 107) restrict the lateral displacements of the conductive elements (101, 102). Moreover, the cover (100) may be integrally formed with the chassis (110), or may be provided with fastening means (103, 104) for attached removably to the chassis (110).

Abstract: Several embodiments of toy dart launch apparatus are disclosed including two crossbows with stretchable cords, a spring driven apparatus and an apparatus with battery operated rotatable wheels. Each apparatus includes an open top drum for receiving and storing darts. The darts are tubular and formed of soft foam. The drum includes an open outer surface with spaced recesses so that loaded darts are exposed, the darts being received by a spike in each recess. The recesses also include protrusions for restraining the stored darts on the spike, and a platform is mounted in the crossbows to support each dart when the released stretched cord impacts the dart. In the case of a rotating wheel arrangement, there is no need for spikes on drum or a platform.

Abstract: Certain embodiments of the present disclosure describe a trigger assembly for use in a crossbow. The trigger assembly includes a floating sear that is able to translate with a cable catch as the cable catch is rotated and also may rotate relative to the cable catch. As the cable catch moves from an uncocked position to a cocked position, the floating sear engages a pivot beam that is engaged with a trigger mechanism.

Abstract: The multiple shot spear gun includes a central rotary shaft having a plurality of relatively stationary spear launching tubes or barrels distributed therearound in a cylindrical pattern. The number of spear launching tubes or barrels is not limited, but may comprise any practicable number. Rotation of the central shaft causes a disc to rotate. The disc has a ramp or tang thereon that sequentially engages the trigger of each of the spear launchers as the disc is rotated. A safety disc is rotated with rotation of the central shaft. The safety disc includes a plurality of holes therein. A spring-loaded catch engages one of the holes as the disc rotates with rotation of the central shaft. Thus, the operator of the multiple shot spear gun must release the safety catch after each shot to rotate the central shaft further for the next shot.

Abstract: Apparatus and method for de-cocking a crossbow. The apparatus includes: (a) a body adapted to attach to a crossbow, the body having a channel therethrough and a threaded bore therethrough intersecting with the channel; (b) a notched wedge adapted to slide through the channel; and (c) a threaded stud so that when the wedge is slid through the channel and the threaded stud is threaded into the threaded bore, the stud can contact the wedge and halt further travel of the wedge through said body. When the body is attached to a cocked crossbow with the bowstring of the bow positioned in the notch of the wedge, the trigger of the crossbow can be pulled to release the bowstring against the wedge and the crossbow de-cocked by unscrewing the stud.

Abstract: A toy arrow that has a shaft with a head end and a tail end is described herein. A head is associated with the head end of the shaft. Fins are associated with the tail end of the shaft. Extending hooks extend outward from the sides of the head.

Abstract: In at least one embodiment, a crossbow comprises a stock, a first limb, a first rotatable member, a second limb and a second rotatable member. A bowstring, a first cable and a second cable each extend between the first rotatable member and the second rotatable member. The crossbow defines a shooting axis. The first cable is offset from the shooting axis in a first direction and the second cable is offset from the shooting axis in a second direction different from the first direction.

Abstract: A bowfishing reel system that can use a standard reel or a normally biased open reel each having a lever that when actuated forces the bail into the open state. A mechanical coupling, such as a string is connected between the lever of the reel and the bow cable or bow string. When the bow is drawn, the mechanical couple causes the lever to be actuated and thus forcing the reel into the open state. As such, when a user goes to shoot an arrow at a target, as soon as the bow is drawn the bail is opened thus preventing back lash and injury.

A front stabilizer or other accessory is secured to the second coupling member.

Abstract: An illumination device for a sight guard and pin for an archery bow, crossbow, or similar weapon or firearm includes at least one fiber optic or other optic element that carries light from an onboard artificial light source to an arc or to pinpoints positioned around the perimeter or circumference of the sight guard. The tip of a sight pin in the sight guard may also be illuminated by the optic element. Light emitted from the optic element is blocked from shining in the direction of the target, but remains visible from the perspective of the shooter. The illumination device enables the user to see the shape of the sight guard and the relative position of the sight pin in low light conditions where reflective tape, glowing materials, and other conventional devices would be difficult to use. Methods of using and activating the illuminated sight guard are also disclosed.
