• the present invention relates to protective shelters such as leisure umbrellas, professional or fairground, usable in any location requiring shelter from the sun or rain. More specifically, the invention relates to protective shelters in which the support is off-center with respect to the canvas in order to completely free the space situated under the canvas.
• the most commonly known parasols are made from a frame comprising the elements called whales and a vertical mast on which slides a slider or lower nut in order to stretch, with the help of whales, the canvas of the parasol.

First of all, by catching in the wind, it creates oscillations which make the balance of the cutlery unstable. During conversations, people opposite are inconvenienced by the presence of the central mast which impairs vision

But the upper nuts 659-660 are below these joints, so that the deployment of the canvas is done under the radial supports 651-652 themselves connected to the connecting rods 661-652, and the assembly secured to the vertical masts according to the methods already described.
• the cables 663-664 shown partially connect the lower sliders 655-666 to fixed points 667-668 of the umbrella frame; this allows the simultaneous opening of the whales during the tilting of the radial supports.
• FIG. 136 shows this assembly in its closing phase, and it will be noted that the fabric escapes the entire frame, thus offering the possibility of complete folding in.
• the cables are only partially represented for the sake of clarity of the drawing.
• the articulation of the truncated masts on the first ends of the radial arms can be carried out on the upper nuts themselves
• This arrangement can be used in all the embodiments previously described to ensure the permanent maintenance of a radial portion of the fabric in the vicinity of the radial arm.
• a radial portion of the latter is constantly maintained in the vicinity of the radial arm, in particular by the weight of the fabric when it is relaxed.
• FIG. 137 illustrates an embodiment in which the sliding nuts 676-676a have a short and inverted stroke compared to the previous embodiments: the inclination of the counterbales is reversed, the folding of the canvas is obtained by bringing the nuts together. 'from one another, while moving them away from the nuts 676-676a produces the deployment of the canvas 632.
• This arrangement can advantageously be used in combination with the deployment means ment of the radial arms 681-68la previously described: a cable 677-677a, integral with the movable nut 676-676a, passes through a pulley 678-678a back, in the tubular central mast, is returned by a pulley 679-679a to the second end of the radial arm where it is secured to the clamping lever 680-680a.
• the short stroke of the cable is compatible with the displacement of the clamping lever, the operation of which produces both the thrust of the radial arm and the complete traction of the movable nut by the cable.
• FIG. 138 represents a mode of projection in space of the frames of the parasol, by means of radial arms composed of segments articulated in cross-pieces 683-683a. These are articulated at their first end on the one hand on fixed rings 684-684a of the frame, and on the other hand along axes 6B5-635a on c ⁇ jlissant rings 686-686a sliding on the frame.
• a cable traction system 687-687a in sheath 687b -687c, known for the maneuvers of the skylights, makes it possible to control, using a handle 688, the movements of the sliding rings 686-686a and thus to trigger the maneuvers of the crosspieces .
• cables 689-689a can optionally be adapted to the lower nuts of the frame and simultaneously trigger the opening of the ribs at the same time as the displacement of the radial supports.
• Stops 690-690a slow the movement of the masts 691 -691a relative to the radial arms.

• Springs 693-693a allow a certain tension to tension the parts of the radial supports.
• Return means 694-694a secured to the frame allow the assembly to be folded.
• the radial supports are also articulated to the frame by known means, and are brought into a horizontal position by springs 694b-694e, suitable.
• the cut masts 695-695a remain vertical, in that the counter whales 696-696a serve as their support on the radial supports.
