FR2844430A1 - Anti-return stop for umbrella has reinforcing struts to support main struts to prevent folding in high winds - Google Patents

Abstract

The anti-return stop for an umbrella has reinforcing struts (4,5) with hinges and stops to form an angle of less than one hundred and eighty degrees to facilitate folding. The ends of the struts are fixed and hinged on the main struts (1) of the umbrella, with one end attached to the opening slide (6) on the handle (3) or on the opening struts.

Description

DESCRIPTION

  -1 The present invention relates to an anti-overturning device for umbrellas, parasols, and parasols. This device has the property of preventing the hazards consecutive to situations of overturning and deterioration of umbrellas, parasols, and parasols, during gusts of wind. Its implementation has the consequence of remedying these drawbacks, and of adapting to all forms and all types of umbrellas, parasols, parasols, foldable or not. The current frames of umbrellas, parasols, and parasols, have a cantilevered part between the end of the main whales, and the end of the opening whales,

  thus offering a large wind catching surface which facilitates the reversal.

  The device according to the invention overcomes these drawbacks. According to a first characteristic, it in fact comprises so-called reinforcing ribs, which are articulated towards their midpoints and have a stop to maintain an opening angle less than 1800 in order to facilitate the folding of these elements. One end of these whales is connected to the slide or on the opening whales, the other end is fixed and articulated at the end of the original main whales (framework), and the so-called reinforcement whales 15 avoid these. ci to turn around during gusts of wind. When closing, the so-called reinforcing ribs fold up next to and parallel to the main ribs (framework) and the opening ribs. The device improves the wind resistance of umbrellas, parasols and

  umbrellas, and prevents them from turning over and deteriorating during gusts of wind.

  According to particular embodiments:

  - The device can be round, square, rectangular, etc.

  - The device can equip either rigid or folding elements.

  - The device composition material is determined by the state of implementation according to

manufacturing possibilities.

  - The device adapts to all forms and all types of umbrellas, parasols or parasols.

  The accompanying drawings illustrate the invention:

  Figure 1 shows a top view of the device according to the invention.

  Figure 2 shows in section A-A the device according to the invention.

  Figure 3 shows detail A of the assembly of the reinforcement and opening ribs

  on the slide of the device according to the invention.

  FIG. 4 represents seen from above the detail A of the assembly of the reinforcement and opening ribs on the slide of the device according to the invention.

  FIG. 5 represents detail B of the articulation and the stop of the reinforcing ribs of the device according to the invention. FIG. 6 represents detail C of the fixing and articulation of the reinforcing ribs of the device according to the invention.

  With reference to these drawings, the device comprises the so-called reinforcing ribs (4 and 5) with articulations and stops in order to form an angle less than 180 in order to facilitate the folding of these elements, the ends of the reinforcing ribs (5 ) are fixed and hinged on the original main whales (1), the reinforcement whales (4) are fixed and hinged on the slide (6) guided by the mast (3) or on the opening whales (2) . 10 When closing, the so-called reinforcing ribs (4 and 5) fold back next to and parallel to the main ribs (1) and the opening ribs (2).

  Without limitation, the device can be adapted to all forms and all types of umbrellas, parasols and parasols, rigid or folding.

  The device according to the invention is particularly intended to remedy the effects of overturning and deterioration of umbrellas, parasols and parasols, during blows

Wind.
