<p>Arc-shaped canvas shelter has two side surfaces (2,2') by which it rests on ground. Sides are separated in their upper part by two small size front surfaces (3,3'). It comprises frame constituted from flexible strip (4) which is introduced in runner forming sheath (5) . Sheath is composed of two symmetrical sections (51,52) intersecting in their central part (6) such that in absence of any external stress strip is resiliently returned to deployed position where it is held by tension of canvas. An independent claim is also included for the method for folding the canvas shelter.</p> |
