An automated balloon inflation device (200) which has a supply of pressurize d gas (202), a nozzle (222) for receiving a balloon (224), and an actuator for closing a clamp (216) on the balloon and the nozzle (222 ) and subsequently supplying the gas (202) to the balloon (224) for the inflation thereof. A key-weight device (94) is employed for controlling the supply of gas to the nozzle and to prevent the loss of a balloon which is secured to the key-weight. The device is constructed so tha t any consumer may inflate a balloon. The device employs a connection block (205) with a series of conduits therein to interconnect the gas supply with the clamping mechanism (216) and the nozzle. The clamping mechanism (216) uses a piston (264) attached to a gear Q266) wherein the gears (270) rotate clamping jaws (274) onto the nozzle (222). A door trigger mechanism (256) is provided which only allows g as to flow to the nozzle and clamping mechanism when the door is closed.
