Abstract: A lighting balloon including a deformable envelope, at least one lighting mechanism mounted inside the envelope, and a supporting and stretching mechanism for the envelope, including a plate carrying the lighting mechanism and with a longitudinally extending distancing element mounted on the plate. The supporting and stretching mechanism cooperates with an apex and a base of the envelope to stretch the envelope in the longitudinal direction. The balloon further includes at least one shape-maintaining mechanism mounted on the envelope and arranged transversely in relation to the distancing element.

Abstract: A lighting balloon including a deformable envelope, at least one lighting mechanism mounted inside the envelope, and a supporting and stretching mechanism for the envelope, including a plate carrying the lighting mechanism and with a longitudinally extending distancing element mounted on the plate. The supporting and stretching mechanism co-operates with an apex and a base of the envelope to stretch the envelope in the longitudinal direction. The balloon further includes at least one shape-maintaining mechanism mounted on the envelope and arranged transversely in relation to the distancing element.

Abstract: An illuminating balloon with an inflatable envelope contains an illumination system having at least one electric light bulb, and inflating means equipped with an integrated fan designed to suck air in from the outside and to inject it into the envelope while keeping the latter in the inflated state. The assembly formed by the bulb and fan is covered by a bowl made of transparent or translucent plastic material, forming an explosion-proof isolating shield and a deflector of the discharge air for inflation of the envelope via passage apertures provided in the bowl.

Abstract: A balloon includes an envelope inflatable by a gas, in particular air, an anemometer for detection of the wind speed outside the envelope, and a control circuit to control a fan so as to make the internal inflation pressure of the envelope vary according to the wind speed. The upper part of the mast passes vertically through the envelope to give the latter a static rigidity at the level of the diametrically opposed bottom pole and top pole. The mast is hollow and includes at least one air outlet orifice in its upper part to perform inflation of the envelope.

Abstract: The illuminating balloon comprises at least one standard module having an inflatable envelope housing an illuminating device. The envelope of each standard module comprises external connecting means designed to co-operate, by juxtaposition according to a predefined shape, with the complementary external connecting means of a predetermined number of identical standard modules to adjust the global volume of the illuminating balloon. Each standard module is formed by two adjacent flat side faces and by a transverse surface. The external connecting means of each standard module comprise lateral connecting means fixed onto the contour of the flat side faces, and transverse connecting means fixed onto the transverse surface. The two flat side faces are substantially in the shape of an ellipse and the transverse surface is a curved revolution surface.

Abstract: An illuminated inflatable balloon, with an envelope inflated with a gas, is connected to the ground by an elongate element. The envelope encloses an electrical bulb connected to an electrical power supply. Spring loaded filar elements are sensitive to the deformation of the envelope, as well as the internal pressure of the gas. The spring loaded filar elements cooperate with a control hairpin for actuating a switch interposed in the connection between the bulb and the electrical supply in order to make and break the connection on either side of a predetermined threshold.
