    Abstract: A toy gun in the form of a breech loading rifle is provided which is capable of firing a projectile such as a dart as well as simultaneously or near simultaneously emitting smoke from the muzzle of a barrel of the gun after the dart has been discharged from the muzzle. The toy gun has first and second rechargeable air pumps. A first one of the air pumps automatically discharges stored air into a breech part of the barrel in order to propel a loaded projectile from the gun's barrel. A second one of the air pumps expels stored air through a flow restriction device which doubles up as a pressure switch for actuating a smoke generator located adjacent to the muzzle of the gun. The second air pump also provides a low flow rate of air through the smoke generator to expel smoke from the smoke generator. The second air pump expels stored air much more slowly than the first air pump. The first and second air pumps are simultaneously triggered to release stored air by user actuation of a trigger of the gun.

  • Patent number: 8398449
    Abstract: A light-weight toy is attached to a player via a near-invisible fixed-length tether, typically using a low-tack adhesive at the ends of the tether. In especially preferred embodiments, the toy has a mechanism that creates an appearance of plausible possibility of flight without actually providing sufficient lift and/or propulsion for flight. Imaginary flight is achieved by manual lifting and moving the toy via the tether. Thus, the tether forms an integral part of the imaginary play for the player and is not used as an implement of a ‘magic trick’ for an audience.

  • Patent number: 7789729
    Abstract: A toy gun is provided with ejecting shells and a smoking chamber. Each ejecting shell has a spring and a recess and is placed into a barrel chamber. The chamber has a post, which compresses the spring when the shell is placed into the chamber. When the hinge is opened, the spring decompresses ejecting the shell from the chamber. The smoke generating assembly is provided with a pump, an oil tank, a heating element, a switch, a visual indicator, and an automatic shutoff. When the switch is actuated, the heating element heats the oil, such that it transforms into a smoke vapor. Upon opening the hinge, the hinge actuates the pump, connected to the tank, which pumps smoke vapor out of the tank through an opening in the post such that smoke appears in the chamber.

  • Patent number: 7749040
    Abstract: A smoke production system for a model locomotive capable of accurately simulating the exhaust characteristics of an actual locomotive. The present invention accomplishes this by monitoring the rotation to the flywheel of the electric motor used to drive the drive wheels of the model locomotive. Various devices may be used to monitor the rotation of the flywheel. For example, a magnet is employed on the flywheel and a magnetically-reactive element such as a reed switch or Hall effect sensor is positioned adjacent to the flywheel. Alternatively, an opticoupler or cam may be used to track the rotations of the flywheel. A controller counts the rotations of the flywheel and actuates a smoke production device to emit smoke four discrete times for every rotation of the model locomotive's drive wheel.

  • Patent number: 7727097
    Abstract: A sport novelty ball has an outer shell and a stabilizing shock absorbing core in which various interior components are embedded. A non-toxic smoke solution is introduced into the ball and stored. Centrally located within the ball is a smoke chamber containing a heating element, A switch/pump assembly is provided for completing an electrical circuit and moving the smoke solution through the ball. Upon actuation of the switch/pump assembly, simultaneously the heating element is actuated and the solution is pressured through fluid lines in the ball to an atomizer for spraying the solution onto the heating element, whereupon smoke is generated in the smoke chamber. Exhaust/intake channels extend from the smoke chamber to the ball periphery. When the ball is thrown, ambient air passing through the exhaust/intake channels causes a stream of air to be emitted from the channels, giving the appearance that the ball is smoking.

    Abstract: A smoke-filling-bubble generator has a smoke generator, at least one blower and a nozzle assembly. The smoke generator may contain nebulizaing liquid and is able to generate smoke. The blower generates airflow to blow the smoke generated by the smoke generator. The nozzle assembly includes a swaying arm and a nozzle mounted on the swaying arm. The swaying arm controllably dips the nozzle into suds contained in a cup and inserts the nozzle into an outlet from which the smoke is blown. With the smoke gradually blown out of the outlet, bubbles containing smoke are individually formed in the nozzle and fly into the air. In such a manner, when the bubbles burst in the air, the smoke may emerge out and mix up the bubbles to present a novel effect that is dazzling and magical. Therefore, the smoke-filling-bubble generator provides a unique entertaining effect.
