ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to expandable bladder guns for dispensing fluid, and more specifically, to a toy gun having an expandable bladder which can be charged via an auxiliary connection to a pressurized fluid source.
Guns for ejecting a fluid which include a bladder that is expanded upon having a fluid pumped into it and which use the elastic property of the bladder as the motive force for discharging the fluid are known. One such gun, described in Applicant's prior U.S. patent application Ser. No. 08/672,941, filed on Jun. 28, 1996, now U.S. Pat. No. 5,799,827, which is incorporated by reference as if fully set forth, utilizes a bladder arrangement in the gun housing which is charged using a pump located on the gun to move liquid from a storage tank located on the gun into the bladder. This type of gun has proven to be extremely popular. However, a user is required to manually actuate the pump which takes additional time and may be difficult for younger users. In most instances, an external pressurized fluid source, such as public water, is generally available. It would be desirable to allow rapid charging of a gun without the need for using a manual pump. It would also be desirable to provide a gun having a large capacity to increase the time between refills without the disadvantage of having a reservoir on the gun making the gun heavier and more difficult to wield.
SUMMARY OF THE INVENTION
Briefly stated, the present invention provides a gun assembly comprising a backpack assembly having a first restricter tube. The first restricter tube has first and second ends, with the first end having an opening. An expandable bladder having two ends is located within the first restricter tube. The first end of the bladder has an opening located at the opening of the first restricter tube and the second end of the bladder is closed. A supply manifold is located at the first end of the first restricter tube and is connected to the first end of the bladder. The supply manifold has a discharge end and is in fluid communication with the bladder. A remotely located gun is provided which has a gun manifold which is in fluid communication with the discharge end of the supply manifold.
In another aspect, the present invention provides a combination of a gun assembly and a quick charge adapter for charging the gun assembly from an external source of pressurized fluid. The gun assembly includes a backpack assembly and a remotely located gun for discharging a fluid. The backpack assembly includes a first restricter tube. The first restricter tube has first and second ends, with the first end having an opening. An expandable bladder is located within the first restricter tube. The bladder has two ends, with the first end having an opening located at the opening of the first restricter tube. A supply manifold is located at the first end of the first restricter tube and connected to the first end of the bladder such that the supply manifold is in fluid communication with the bladder. The supply manifold has a discharge end. The remotely located gun includes a housing with a gun manifold located in the housing and in fluid communication with the supply manifold via a connection such that fluid can flow between the supply manifold and the gun manifold. An ejection nozzle is provided in fluid communication with the gun manifold. A trigger is located on the housing, and a release valve is connected to the trigger. The release valve is in fluid communication with the gun manifold whereby activation of the trigger activates the release valve to discharge fluid from the ejection nozzle. A recharge nozzle is provided in fluid communication with the gun manifold and is adapted to be inserted into a recharge adapter such that pressurized fluid flows from the recharge adapter into the recharge nozzle, through the gun manifold to the supply manifold and to the expandable bladder such that the bladder is expanded by the pressurized fluid. A recharge adapter is provided and is adapted to be connected to a pressurized fluid supply. The recharge adapter includes a receptacle which is adapted to receive the gun recharge nozzle.
