Definitions

  • the subject of the invention is a basket comprising on the one hand a fabric stretched between a roller and a load bar and on the other hand articulated arms connected by one of their ends to the load bar and by their other end to supports integral with a bar parallel to the load bar in order to be able to adjust the inclination of the fabric.
  • the adjustable inclination is difficult to obtain given the constraints brought by the general frame of the awning, especially if it is large.
  • a blind of the awning type which comprises a "blind holder” provided with a torsion bar which serves as a link between this blind holder and fixed supports.
  • the torsion bar in addition to its role of mechanical connection, aims to create a pre-stress thanks to which the effort to be made to pivot the blind holder is lower than what it would be in the absence of torsion bar.
  • the movable part of the blind holder is equipped with one or more clamping heads making it possible to block the blind in the desired position.
  • the known arrangements act by all or nothing, depending on whether the mobile part is blocked or unlocked before moving it.
  • the efforts of weight and of pivoting stresses are entirely and exclusively supported by the bearings or supports 6 and 7 for which the resistance value is suitably adjusted.
  • each of these arms assumes that considerable efforts are made, representing several tens of kilos, and require the intervention of at least two men and very often the setting of the load bar with makeshift means.
  • the arms 32 are fixed to the bar 4 by means of a ring 24 which is locked by a screw 51 in the chosen position as specified on page 2 last paragraph of column 1 and first paragraph of column 2.
  • Patent FR-A-1,558,274 describes a blind of the same type as those described in patents FR-A-1 396 200 and FR-A-1 550 331, namely that the arms are individually adjustable in inclination relative to a bar a which is fixed as explained on page 1 , column 1, lines 24 to 26.
  • the awning according to the invention differs from these known devices in that it comprises arms which are fixed on a common bar, which is mounted in fixed bearings comprising a friction system of preferably adjustable. According to the invention it is impossible to rotate the arms without simultaneously rotating the bar which joins them.
  • the present invention aims to simplify the construction of orientable banners in order to make them not only more practical but also more economical.
  • the subject of the invention is a basket comprising on the one hand a rotary roller, a load bar and a canvas wound on the roller and fixed by its free edge to the load bar and on the other hand supports and compasses whose articulated arms are movable in the same plane and are further articulated by one of their ends each to a support and by the other of their ends to the single load bar, the different pivots of articulation of the arms all being of axis perpendicular to the plane of the compasses while the supports are integral with a bar parallel to the load bar characterized in that this bar (5) is pivotally mounted in bearings which must be fixed under the roller and which are of the permanent friction type, the value of which, preferably adjustable, is established below a blocking value so that the shutter can, without acting on the bearings, be pivoted.
  • the single figure of the drawing is a partial schematic view of a screen according to the invention.
  • the awning comprises articulated arms 1 and 2 connected by one of their ends to a load bar (not shown) and by their other end to supports 3-4 placed on a bar 5 the ends of which are engaged in friction bearings 6 and 7 fixed by any means, preferably adjustable, to the facade which is to receive the awning.
  • the bearings 6 and 7 contain surfaces (not shown) with a high coefficient of friction due to their relative roughness.
  • the bar 5 is constantly immobilized in the orientation which it occupies thanks to the friction obtained in the bearings 6 and 7, the whole being produced by means which are within the reach of those skilled in the art.
  • the friction is permanent and is established at a value sufficient to oppose the accidental pivoting of the bar 5 for example under the effect of the normal wind acting on the canvas that the articulated arms 1 and 2 keep taut.
  • the bar 5 receives at least one element such as a ratchet wheel 8 and 9 capable of receiving the action of a lever-forming tool such as a wrench.
  • One has teeth tilted in one direction and the other has teeth tilted in the opposite direction.
  • the bar 5 has a non-circular section, in this case square.
  • the two ratchet wheels 8-9 have a central passage, also square in section, and are engaged on the bar 5. An action with the key A on one of the two ratchet wheels 8-9 has the effect of driving the bar. 5 in pivoting since the square passage of the ratchet wheels opposes the pivoting of the latter relative to the bar 5, itself of square section.
  • the shade can be varied to increase or decrease it, regardless of the advance, i.e. the length of the canvas unrolled and the position of the compasses. .
  • the ratchet wheel 8 can freely slide along the bar 5 according to the double arrow F3, in one direction or the other which allows the user to place it in the place which seems to him the best and possibly change this location whenever he wants.
  • the ratchet wheel 9 is equipped with a radial screw 10 which bears against the bar 5 when it is screwed in order to oppose the free sliding of the ratchet wheel 9 along the bar 5.
  • the friction force of the bearings 6 and 7 must be relatively large taking into account the surface of the fabric, the weight of the assembly and the external stresses such as, essentially, the force of the wind.
  • the tool A must provide a relatively large lever arm so that a user can orient the fabric without excessive fatigue.
  • the friction bearings 6 and 7 are fixed to the facade by any known means and preferably adjustable to compensate for the irregularities of this facade or the imperfections of the assembly.
  • the bar 5 constitutes a real coupling both of the arms 1 and 2 and of the bearings 6 and 7, in such a way that when one acts on the load bar or on an accessory device 8-9, the arms are used ( or tool A) in the manner of a lever arm to move the entire hitch (load bar-arm 1-2-bar 5) and this without angular limitation, unlike what happens, in particular, with the device described in patent FR-A-2 127 434 and whose angular movement is linked to the operation of a torsion bar.
