DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE DISCLOSURE
1. Field of the Invention
The invention relates generally to a closure head for a gas balloon, and more particularly, to a closure head intended for strings of air balloons having associated closure heads connected to a common supply cable along which the balloons are distributed at intervals from one another. The supply cable may include a pneumatic supply line for inflation of the air balloon, a pneumatic return line for deflation of the air balloon, electrical supply conductors for an electric lamp disposed in the closure head and intended for internal illumination of the air balloon and/or electrical supply conductors for a sound radiator such as a loudspeaker disposed in the closure head.
2. Description of Related Art
In the prior art, closure heads employing electrical lamps for illuminating air balloons are known. In such devices, the electrical lamp is screwed into a lamp socket to which conductor wires are connected. The conductor wires are led in vacuum-tight fashion out of the closure head on the side which is remote from the lamp socket and are connected to electrical terminals disposed on the outside of the closure head for connection to a cable leading to an external current source. It is also known per se to provide electric lamp sockets for incandescent lamps with electrical connections which take the form of piercing contact elements so that the lamp socket can be clamped onto a two-core flat cable establishing electrical contact between the piercing contact connections of the lamp socket and the conductor cores within the flat cable.
SUMMARY OF THE INVENTION
According to the invention, a closure head for a gas balloon is provided which can be fixed directly to a supply cable. A supply cable including first and second pneumatic channels is sealably introduced by a clamping means into the interior of the closure head housing, one end of which is adapted to mount the balloon. First and second check valves employing hollow needle tips are arranged to communicate with the first and second channels in order to inflate and deflate the balloon. According to an additional feature of the invention, the first and second needle tips may contact first and second electrical conductors in order to activate a lamp for illuminating the balloon. Alternatively, a second cable carrying electrical conductors may be mounted adjacent the supply cable and additional piercing elements arranged to contact the electrical conductors.
The invention has the advantage that the closure head may accommodate an electric lamp for internal illumination of the air balloon and/or a sound irradiator, which are coupled via associated piercing elements to the associated supply lines, the particular associated piercing element in the housing being connected to an electrical conductor which leads to the associated connection of the relevant energy irradiator.
Additionally, the direction of closure of the check valves are advantageously directed in opposition to one another. As a result, it is possible to inflate the gas balloon using the first check valve, which is maintained closed by the pressure inside the gas balloon after inflation. In consequence, the inflated balloon cannot be deflated through the associated pneumatic supply line if, for example, another gas balloon in the chain happens to burst. With respect to the second check valve, it is possible to maintain a holding pressure via the associated supply line of the cable which maintains the second check valve closed against the internal pressure of the inflated balloon. If there is a need for the gas balloon to be deflated, the supply line associated with the second check valve may be vented, so that the associated check valve opens under the pressure inside the gas balloon. Such operation may be advantageous, for instance, when a string of gas balloons is suspended in a garden and a strong wind blows up which might cause the inflated gas balloons to burst, due to the large surface area which they offer when inflated. In such case, it is
