Abstract

A hand operated water gun which utilizes a base section which can be mounted on the upper arm of the user or carried by the user. The base section may include an elastic bladder and a pumping apparatus. The elastic bladder connects with a reservoir. The pumping apparatus is manually operated by a movable section which can comprise a handle. The movable section is pivotally mounted to the base section. Movement of the movable section causes water to flow from the reservoir into the elastic bladder causing the elastic bladder to expand. A discharge nozzle is connected to the elastic bladder with the discharge nozzle being normally closed preventing flow of water therethrough by a discharge valve. The discharge valve is to be manually openable to cause the dispensing of the water in the form of a stream. The water is to be supplied into the elastic bladder until it expands to a certain degree prior to opening of the discharge nozzle. A pressure relief valve is mounted in conjunction with the elastic bladder to help such from over expanding. Different configurations of fill valve may be used to fill the reservoir with water.
