Title:
【発明の名称】照明手段を備えた膨張可能気球
Document Type and Number:
Japanese Patent JP3267624
Kind Code:
B2
Abstract:
The balloon (1) has a flexible outer surface (1) which is connected an electric cable with an outer sheath (27). A sealed connection through the balloon wall is made by an outer plate (4) with inner ring and sealed connections (13). Nut connections (28) on the outer wall allow connection to an inner section. The cable connects a power source on the ground to a light in the centre of the balloon. An actuation device inside the balloon consists of a spring (7) which is tensioned by a flexible connector and connected to the loop (17) of a two-sided pin (19). Switches (25) are positioned between the power source and the light. A wire (5) links part of the surface and the actuator which is positioned at another location at the surface periphery. The pin has a sliding holder (24) and an inner spring (15). The pin base (21) is clear of the switch (26) when the balloon is inflated, but pushes the switch closed when the balloon is deflated, switching off the electricity.
