ABSTRACT:
A framework forming support for a tent canvas of a light shelter which is stretched in substantially pyramidal form, abutting, at its center, on the top of a vertical central pole, comprises a rigid frame in the form of a regular polygon, defining the base of the pyramid and to the sides of which the canvas is hooked. The lower end of the central pole being is located at a level higher than the horizontal plane of the polygonal frame. The pole is maintained vertically by inclined rigid arms whose upper ends are rigidly coupled, in common, to the lower end of the pole. The lower ends of the arms are coupled to the sides of the polygonal frame, the points of connection of two adjacent inclined arms with two adjacent sides of the frame being symmetrical with respect to the bisectrix of the angle formed by these two sides. Crosspieces extend respectively across the angles of the frame, between points of hooking on the sides of the frame which are symmetrical with respect to the bisectrix of each angle.
