Title: Light-weight lighting structure sliding on a mast
Inventor: MAUCOURT JEAN-MICHEL
IPC: F21V21/38
Filed: 1987-07-09
Abstract: Light-weight lighting support structure, carrying lamps 6, sliding on a mast and capable of being manoeuvred up and down this mast by an operator using only gentle force, gravity being compensated for by the joint use of a counterweight 8 and a spring. The latter gives the flexibility necessary for immobilising and releasing the structure. The manoeuvre can be performed in complete safety, since the user is never situated within the structure 1. The same means, for example a cable, which allows the manoeuvre to be carried out, allows remote locking and unlocking of the mobile system, using a device such as 13. Centring is ensured by a device such as 7, consisting of truncated pyramids, one fixed onto the mast, the other onto the structure.
