With the configuration including the spring member, it is possible to obtain an illumination balloon having a simple structure and easy to attach to the lifting device.

According to the third aspect of the present invention, by raising the uppermost mast of the elevating device, each of the plurality of spring members is curved into an elliptical shape to inflate the balloon, and the uppermost mast is lowered. By providing an automatic balloon inflation / deflation device that deflates the balloon by returning the spring member to its original stretched state, the electric air suction device conventionally used to keep the balloon inflated can be omitted. It is possible to obtain an illumination balloon having a simple structure and a low cost.

According to the fourth aspect of the present invention, the chrysanthemum seat portions are provided which can be engaged with the lower end portion of the uppermost mast and the lower end portion of the mounting portion of the illumination balloon at the facing surfaces facing each other. By installing a balloon tilt fixing device that engages with each other with bolts and presses the chrysanthemum part on the mounting part side toward the chrysanthemum part of the uppermost mast with a compression spring, It is possible to position it from a vertical state to a horizontal inclined state with a simple operation, and it is possible to easily and easily attach and detach the illumination balloon to the lifting device, and the illumination balloon can be stored compactly, so it can be used on a truck. It can be easily transported and stored in a warehouse.

According to the fifth aspect of the invention, the balloon is fixed to the upper support member, the member does not extend above the balloon, and the uppermost mast is moved up or down to raise the bulb. Since the balloon is inflated or deflated as the leg sliding member moves up or down along the holding leg below the protective frame housing the It is also excellent in terms of surface, and in particular, when the balloon is inflated, it can be used with the illumination position kept high, and illumination over a wide area is possible.

Further, in the invention of claim 5, also in terms of structure, only one pulley for locking the wire rope is required, and it is necessary as a pillar of a protective frame for accommodating the light bulb on the uppermost mast. Since the holding leg portion can be used as a guide when the balloon is inflated or deflated, waste of component members can be eliminated and a configuration with less failure can be achieved.

Further, according to the invention of claim 6, one end of the protection frame body for protecting the bulb of the illumination balloon is brought into contact with the upper support member of the protection frame body, and the other end is supported by the protection frame body. A coil spring that is abutted against the member and is spirally wound around the outer periphery of the protective column of the protective frame, and is provided so as to surround the outer periphery of the coil spring, and one end of the coil spring is attached to the upper support member of the protective frame. Since the other end of the illumination balloon is in a contracted state, the protection frame body is provided with a surrounding net formed in a bellows shape and the other end of which is in contact with the bulb supporting member of the protection frame body. By the surrounding net and coil spring provided to surround the outer periphery of the protective column, the invasion of the inner portion of the balloon that is deflated into the protective frame is prevented,
Since there is no direct contact with the bulb, it is possible to prevent the balloon from being burnt or burned due to the heat of the bulb.

Further, in the unlikely event that the light bulb is damaged, the surrounding net surrounding the protective column of the protective frame can prevent the broken pieces from scattering to the outside.
