DESCRIPTION:
BRIEF SUMMARY
The invention relates to an accessory device for a gas balloon of the type which has an inflatable balloon-envelope defining the interior of the balloon and consisting of elastically expansible material, such as rubber, and on which there is constructed a tube-shaped balloon neck.
Such gas balloons are used widely, for example as children's air balloons, decoration and for advertising purposes. It is also known for the balloon neck to be closed in sealing-tight fashion by means of a sealing head which is introduced into it. Such a sealing head may support an electric lamp for interior illumination of the air balloon. Although this enhances the attractiveness of air balloons, the interior illumination is only perceived in darkness.
The invention resolves the problem of providing an accessory device for inflatable gas balloons by which the attractiveness of such gas balloons is still further enhanced.
The invention provides an accessory device for a gas balloon of the type described in the outset wherein a sealing head is provided for the sealing-tight closure of the balloon neck of the gas balloon, the sealing head being provided with a sound irradiating means which is directed into the interior of the gas balloon after the sealing head has been inserted into the balloon neck and after the balloon-envelope has been inflated.
Such an accessory device makes it possible, for parties, restaurants or garden parties, where air balloon decorations are used, to accomodate in one of the air balloons for example a loudspeaker to serve as a sound irradiating means for directing sound into the interior of the balloon, or alternatively to provide a "talking" balloon or a "musical" balloon for games purposes. With suitable tension in the gas balloon envelope, according to how intensely it is inflated, the balloon-envelope itself can serve as a sound diaphragm improving the tone colour and/or volume of the sound irradiating device.
Although it is possible to accomodate in the sealing head not only the sound irradiating means but also an electroacoustic control device for the latter, such as per se known electronic music computer or music synthesiser, together with the associated power source, in the form of a battery, which can be switched on and off by means of a switch, it is at present preferred to connect the sound irradiating device through electrical conductors to an external electromechanical coupling, e.g. a plug, for electrical connection of the sound irradiating device to an external electro-acoustic control device. Such an electro-acoustic control device may be a per se known microphone system, a radio receiver, a cassette or tape recorder, a music computer or an amplifier system of a musical instrument. Such an electromechanical coupling is preferably so designed and so mechanically connected to the sealing head that in addition to the electrical connection of the sound irradiating device it also constitutes a mechanical coupling for the sealing head to hold the gas balloon. The electro-acoustic control device may be accomodated in a handle part of the accessory device according to the invention. It is however also possible to use an external control device as the electro-acoustic control device. The electromechanical coupling may be a plug-in coupling but is however preferably a rotary coupling such as a bayonet coupling or in particular a screw coupling.
In the particularly preferred embodiment, the electromechanical coupling is a screw-type bulb cap of the size of the screw caps of commercially available incandescent lamps. In consequence, at the same time as the sealing head is fixed mechanically into a holder which has a mating coupling a screw-type lamp socket which is connected to an electro-acoustic control device, switching of the sound irradiating device on and off is achieved by slight rotation of the screw cap in the screw socket, so that a separate switch for this purpose becomes superfluous without the mechanical coupling of the sealing head and thus of the balloon to the mounting thereof being a
