Definitions

  • the subject of the invention is a blind of the awning type, that is to say 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 mounted pivoting about an axis parallel to the load bar in order to be able to adjust the inclination of the canvas.
  • the adjustable inclination is difficult to obtain given the constraints brought by the general frame of the awning, especially if it is of large dimensions.
  • a blind of the awning type which comprises a "blind holder” provided with a torsion bar which serves as a link between this prote-blind 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 efforts of weight and stress pivoting are entirely and exclusively supported by bearings or supports 6 and 7, the resistance value of which 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 is specified paga 2 last paragraph of column 1 and first paragraph of column 2.
  • French patent 1,558,274 describes a blind of the same type as those described in French patents 1,396,200 and 1,550,331, namely that the arms are individually adjustable in inclination relative to a bar a which is fixed as is explained on page 1, column 1, lines 24 to 26.
  • the blind according to the invention differs from these known devices in that it comprises arms which are fixed to a common bar, which is mounted in fixed bearings comprising a friction system preferably adjustable.
  • the known devices act by all or nothing according to that we block or unblock the moving part before moving it.
  • the present invention aims to simplify the construction of such banners in order to make them not only more practical but also more economical.
  • the single figure of the drawing is a partial schematic view of the blind according to the invention.
  • the blind according to the invention is of the awning type, that is to say comprising a frame to be fixed near a bay of a wall and composed on the one hand of a fabric stretched between a roller and a bar load and on the other hand of articulated arms connected by one of their ends to the load bar and by their other end to supports pivotally mounted about an axis parallel to the load bar in order to be able to adjust the inclination of the fabric, characterized in that the supports are subject to a continuous common bar, the ends of which are pivotally engaged in bearings which are fixed to the wall to be fitted and which are of the permanent friction type, the value of which is preferably adjustable, the maneuver which consists in adjusting the inclination of the fabric having to require a greater and antagonistic effort than that pre-established of friction.
  • Such a blind is shown in the drawing where we see 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 front which must receive the awning.
  • the bearings 6 and 7 contain surfaces with a high coefficient of friction either interchangeable or 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 against the linings, the whole being produced by means which are within the reach of man from job.
  • the friction is permanent and is established at a sufficient value.
  • the bar receives at least one element such as a ratchet wheel capable of receiving the action of a lever operating tool such as a wrench and the like.
  • the bar has a non-circular section such as square, and the element is engaged on it by a passage of the same section, a sliding immobilization member being possibly provided on the element to cooperate with the closed off.
  • 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 shadow can be varied to increase or decrease it.
  • 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 neck smoothing 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 arms 1 and 2 and bearings 6 and 7, so that when acting on the load bar or on an accessory device 8 - 9, the arms (or tool A) are used in the manner of a lever arm to move the entire coupling arm 1 and 2 - bar 5 - bearings 6-7 and this without angular limitation, contrary to what happens, in particular, with the device described in the French patent 2,127,434 whose angular movement is linked to the operation of the torsion bar.
