  • Patent number: 6257448
    Abstract: The present invention relates to a gun assembly for dispensing a fluid with a quick charge adapter. The gun assembly includes a plurality of expandable bladders located in housings which are connected to a supply manifold. The supply manifold is connected to a remotely located gun which is adapted to dispense fluid stored in the bladders upon activation of a trigger. The fluid may be dispensed through a selected one of multiple ejection nozzles located on the gun that can be selected by the user. A recharge nozzle located on the gun is adapted to be inserted into the quick charge adapter to quickly expand and fill the bladders from a pressurized supply.

  • Patent number: 6193107
    Abstract: The present invention is a toy water gun for containment and ejection of water which includes a housing, an ejection nozzle, a bladder and an outlet connection which runs from the bladder to the nozzle. The expandable bladder is located in the housing and has a first end connected to the outlet connection and has a carriage attachment located at the second end. The bladder carriage attachment is movable and guided generally linearly in the housing as the bladder is expanded. The bladder is a tubular member having a weakened section with a larger diameter than the remaining portion of the tubular member and has a variable diameter which varies from larger at the first end to smaller at the second end. In one embodiment, the bladder has a variable diameter, larger at it's front end and smaller at it's back end. In another embodiment, the bladder has a constant diameter with a wall thickness gradient. Combined variable diameters and wall thickness may be used.

  • Patent number: 6167925
    Abstract: A toy gun having a housing is provided. A trigger is attached to the housing and a liquid storage tank is provided on the housing along with a pressure chamber having an opening which receives an expandable bladder. Also attached to the housing is a pump which is in fluid communication with the liquid storage tank. The pump is adapted to transfer liquid from the liquid storage tank to the expandable bladder in order to charge the expandable bladder with pressurized liquid as the pump is actuated by a user. In addition, a release valve is included for regulating a discharge of liquid contained in the expandable bladder. A path of fluid communication provides fluid communication between the expandable bladder, the pump, the storage tank and a nozzle assembly. The nozzle assembly is adapted for insertion into a quick charge device. The quick charge device is adapted to force liquid from the quick charge device and through the nozzle assembly in order to recharge the expandable bladder.

  • Patent number: 6158619
    Abstract: The present invention relates to a gun device for dispensing a fluid with a quick charge adapter. The gun device includes a bladder located within a housing. The bladder is connected to a remotely located control unit which is adapted to dispense fluid stored in the bladder upon activation of a trigger located on the control unit. The fluid is dispensed from a remotely located nozzle which may be worn on a user's head. A recharge nozzle located on the control unit is adapted to be inserted into the quick charge adapter to quickly expand and fill the bladder from a pressurized fluid source.

  • Patent number: 6138871
    Abstract: A toy water gun for ejecting a liquid is provided. The toy gun includes a housing and a pressurizable storage tank which receives liquid and is connected to the housing. Also provided on the housing is a pump which is adapted to pressurize the liquid in the pressurizable storage tank. In addition, a release valve is located in the housing. The gun includes a path of fluid communication between the pressurizable storage tank, the pump and the release valve. The release valve is adapted to regulate a discharge of liquid from the pressurizable storage tank, and a trigger is attached to the release valve. Also connected to the release valve is a nozzle assembly adapted for insertion into a recharge adapter to force liquid through the nozzle assembly displacing the release valve in such a way that allows liquid to flow through a part of said path of fluid communication and into the pressurizable storage tank.

  • Patent number: 5906295
    Abstract: The present invention is a toy water gun for containment and ejection of water which includes a main housing, an ejection nozzle, a bladder housing, a bladder and an outlet connection which runs from the bladder to the nozzle. The expandable bladder is located in the bladder housing and has a first end connected to the outlet connection and has a carriage attachment located at the second end. The bladder carriage attachment is moveable in the bladder housing as the bladder is expanded. In one embodiment, the bladder has a variable diameter, larger at it's front end and smaller at it's back end. In another embodiment, the bladder has a constant diameter with a wall thickness gradient. Combined variable diameters and wall thickness may be used.

  • Patent number: 5890295
    Abstract: The present invention is a compound action complex pivotal multi-planar cutting device. It is pivotal between four distinct pivot points and it includes a handle portion and a jaw portion which are attached to one another. The jaw portion may be curved or may be bent and terminates in a pair of opposed cutting blades. Thus, when a user holds the handle portion, the blades are displaced a pre-determined number of degrees with respect to the relative curvature or bending of the jaw portion. The handle portion and jaw portion are engaged to one another and are pivotal about two pivot points. The handle portion is preferably a pair of handles that are joined at a third pivot point by a first post member and the jaw portion is preferably a pair of jaw members joined at a fourth pivot point by another post member which is oblique with respect to the first post member.

  • Patent number: 5875927
    Abstract: The present invention is an expandable tear drop shaped bladder toy gun for subsequent ejection of liquid therefrom. It includes a main housing having a liquid ejection nozzle, a handle and a trigger, as well as an inflatable tear drop shaped bladder connected to or encompassed in the main housing, and includes a single inlet/outlet tube connected to the bladder. There is also a storage tank for supplying liquid, e.g. water, thereto, as well as a hand pump connected to both the storage tank and the bladder. The pump is physically connected to the housing and functionally connected to the storage tank and the bladder inlet. There is a bladder release valve having an upstream side and a downstream side. The bladder release valve is connected to the bladder outlet at the valve's upstream side, and is connected to the trigger for opening and closing thereof, and is connected to the nozzle at the valve's downstream side for subsequent liquid ejection when the trigger is pulled.
