Abstract (en)
1. Framework forming support for a substantially pyramidal tent canvas of a light shelter which is stretched between the top of a vertical central pole and a polygonal base, said framework comprising a rigid frame in the form of a first regular polygon, to the sides (15) of which the canvas (1) is hooked, the pole being maintained by inclined rigid arms of which the ends are coupled, in common, to the pole, characterized in that the lower end of the central pole (4) is located at a level higher than the horizontal plane of the polygonal frame (3), the lower end of the pole (4) is rigidly coupled to the upper part of said inclined rigid arms (5) of which the lower parts are coupled to the sides (15) of the polygonal frame (3), at points of connection (14) spaced apart from the apices of the polygonal frame (3), the points of connection (14) of two adjacent inclined arms (5) with two adjacent sides (15) of the frame (3) being symmetrical with respect to the bisectrix of the angle formed by these two sides (15), and crosspieces (6) extending respectively across the angles of the frame, between points of hooking (16) on the sides of the frame (3) which are symmetrical with respect to the bisectrix of each angle, thus forming a second polygon inscribed in the first with a number of sides double that of the first polygon, the high part of the pole (4) being connected to the canvas (1) which is stretched between this upper part and the first polygon.
