Embodiment Construction

[0037] Such as figure 1 As shown, the collapsible and expandable system for protection against bad weather (rain) or sun - as an umbrella - comprises: a trunk (31) with a double skeleton made, for example, of different materials and two Protrusions - a fixed protrusion (2) and a movable protrusion (1), on which the ribs of each skeleton are fixed. The movable protrusion is connected with the main body by an extensible spring, so that an axial mechanical force ( Figure 1a ). The stronger the wind, the more the movable protrusion (1) compresses the extendable spring against the socket.

[0038] The first skeleton ( figure 1 ) includes a group of umbrella ribs (6) fixed on the fixed protrusion (2) through one end and a set of rods or forks (25), each fork is hingedly connected with an umbrella rib (6) through one end on the one hand , and on the other hand is hingedly connected by an opposite end to a part (19) called a slide, which is mounted so as to be movable along the t...

Abstract

The invention relates to a system such as a foldable and unfoldable umbrella, sunshade, or parasol for protection against bad weather, including: a pole (31), at least two bushes (12), two frames, two series of wind removal openings (8, 9), three mutually overlapping coverings (7, 10, 22) maintained by series of adjusters having a resilient core (20), and two safety springs (3, 4). At least two wind passages are defined by the second and third covering based on a predetermined speed.

Description

technical field [0001] The present invention relates to a collapsible and unfoldable system - such as an umbrella, parasol or sunshade - which forms a complete resistance to wind from the inside to the outside (anti prise) and a partial resistance to wind from the outside , to withstand severe weather with light, moderate and very strong winds. Background technique [0002] Currently, it is difficult to keep an umbrella when it is raining and windy, and in sunny areas with strong winds it is not uncommon to see parasols or similar umbrellas being blown away by the wind. The aim of the present invention is to solve at least one of these problems. Contents of the invention [0003] The present invention generally relates to a system that can be deployed, having a generally decreasing circular shape from the axis towards the coronal circumference when used as an umbrella or parasol, and a substantially decreasing shape when used as a square or rectangular parasol rectangle....
