  • Patent number: 4887583
    Abstract: A safety device for a toy gun has first and second firing pins which can block movement of a trigger. The firing pins are electro-magnetically operated. The first firing pin is normally in a position which blocks movement of the trigger and the second firing pin is normally in a position which allows movement of the trigger. A power source is connected to the first firing pin by a switch so that trigger movement is blocked by the first firing pin until the switch is activated. The switch also connects the power source to a photo-electric switch which includes a light emitter and a light sensor. The second firing pin is connected to the power source by the photo-electric switch so that movement of the trigger is blocked by the second firing pin only when the photo-electric switch is closed. The photo-electric switch detects the presence of a target within a preset range of the toy gun and closes if a target is detected.

  • Patent number: 4834059
    Abstract: A gun, which compresses a spring during cocking and uses the air accelerated by the spring to propel a projectile during firing, incorporates several safety features. The size of the handle makes it impossible for children to operate. The trigger cannot be moved to its firing position unless the gun is cocked, the gun housing is closed, and a manual safety button is actuated during firing. To prevent unintended projectiles from being inserted into the barrel, the front of the barrel is blocked except during firing and the rear of the barrel is blocked at all times by either the projectile-carrying magazine or a barrel block.

  • Patent number: 4318389
    Abstract: A spear gun is collapsible to approximately one-half of the full length of a conventional spear gun by the use of both (1) a spear made of two parts and (2) by the use of a hollow shortened spear gun housing from which an extension for holding the slings or elastics for propelling the spear may protrude. The extension is slidably mounted within the hollow spear gun housing and has at its outer end a sling holder, or arrangements for holding the slings or elastics. The spear has a threaded coupling halfway along its length so that the spear may be unthreaded and the two parts thereof both secured along the length of the housing. One of the parts may be stored on the gun when the gun is not in use. A special compact trigger mechanism may include a release shaft in the hand grip of the spear gun which interfits with a recess in the spear, and is provided with a thumb actuated release. Concurrently with releasing the spear, the other end of the shaft includes a mechanism which releases the spear retaining line.

  • Patent number: 4214674
    Abstract: A toy water gun assembly capable of ejecting water in bursts or in a continuous manner, is disclosed. A separate, pressurizable water container is connected by a flexible hose, to a pistal shaped member. A section of the flexible hose, mounted in the pistol shaped member, is continuously clamped by a lever. A spring biases the lever to prevent the release of a water stream through a nozzle which is mounted on the front of the pistol shaped member. A trigger member having a pointed pawl pivotably mounted thereto, is operatively connected to the lever. An initial movement of the pawl member caused by a quick pull on the trigger member momentarily removes the lever from its position clamping the hose. Additional movement of the pawl causes it to slide off the lever, thereby allowing the lever to return to its regular position wherein the hose is clamped.
