Abstract: A CEW includes a handle and one or more cartridges. A cartridge may cooperate with the handle to launch one or more electrodes. Launched electrodes fly toward the target to couple to the target to provide a stimulus signal through the target to impede locomotion of the target. Prior to launch, detents may retain an electrode in a bore of the cartridge. The bore may be sealed with a door. Launching the electrode may remove the door from the cartridge. The door may couple to the electrode. The door may remain coupled to the electrode during flight and impact of the electrode with the target. The door may cushion the impact of the electrode against the target. Cushioning the impact may reduce the likelihood of injuring the target. Retaining the door coupled to the electrode during flight may improve the flight characteristics of the electrode.

Abstract: A bow and arrow toy having a light-weight, foam tipped arrow and a bow with rear and fore tension bands. To load and arm the toy, the rear of the arrow is abutted against the rear tension band and the shaft of the arrow is pressed against the fore tension band and drawn back. As the arrow is drawn back, the shaft of the arrow slides against the fore tension band until the fore tension band falls into an engagement slot along the shaft, causing the fore tension band to also become engaged and tensioned as the arrow is drawn back further. At the fore outside edge of the engagement slot is a catch lip which protrudes outwards from the shaft and functions to guide the fore tension band into the engagement slot if the pressure of the shaft against the fore tension band is not sufficient to cause the fore tension band to slide directly into the engagement slot. The fore tension band is comprised of three interlinked loops, with the central loop being sleeved so as to narrow its effective diameter.

Abstract: An underwater hunting gun of the crossbow type uses push-rods for tensioning elastic links, the push-rods being placed laterally on a moving headpiece activated by a lever-operated arming system. The elastic links run freely around the push-rods such that front ends of the elastic links are permanently and preferably fixed to the base and rear ends are fixed under no tension in a slot of a bolt or arrow. The sliding of the moving headpiece in the forward bolt-support segment intensifies the drawing of the elastic links from the back forwards over and under the push-rods, thus optimizing, at the time of firing, the range of the bolt without recoil of the crossbow through the fact that the bolt is expelled in the manner of a whiplash. The crossbow incorporates a power regulator and an arrow rail offering stealthy firing suited to the range to the target.

Abstract: A spear gun includes two spears disposed in laterally spaced relation to one another. A separate trigger is dedicated to each spear. Each spear is received within the lumen of a forward spear guide tube and a rearward spear guide tube. Each forward spear guide tube includes a laterally extending post to which is attached the forward end of an elastomeric member. The rearward end of each elastomeric member engages an inclined notch formed in the trailing end of its associated spear. The trailing end of each spear is notched and the notch is engaged by a mating notch formed in a pivotally mounted detent plate. Pulling a trigger pivots the detent plate so that the notches disengage and the bias on the elastomeric member unloads to propel the spear forwardly. A safety latch prevents pulling of the trigger by preventing pivoting of the detent plate.
