Illuminating inflatable balloon
First Claim
Patent Images
1. An illuminated inflatable balloon, comprising:
- an envelope inflated with a gas, said envelope being connected to the ground by an elongate element;
illumination means enclosed within said envelope and electrically connected to an electrical power supply;
actuation means sensitive to one of a deformation of said envelope and a variation in an internal pressure of the gas in said envelope, said actuation means cooperating with a control member; and
switching means interposed in the electrical connection between said illumination means and said electrical power supply, said electrical switching means being actuated by said control member in order to manipulate the electrical connection between an open position when said internal pressure within said envelope is on a first side of a predetermined threshold and a closed position when said internal pressure within said envelope is on a second side of said predetermined threshold.

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.
