Definitions

  • the canvas is fixed by one of its edges to an upper roller capable of being rotated, by hand or mechanically.
  • the deflection bar is an important gene because it remains permanently across the bay, at its lower part, where it constitutes an obstacle to the free movement of people, vacuum cleaners , carts, trolleys, etc.
  • the window is a window located above a sill but the defect becomes prohibitive if the window is a French window because the deflection bar constitutes a real barrier, opposing the free passage and forms an element that is very unsightly to view.
  • the present invention overcomes all these drawbacks and makes it possible to produce a blind with two plies, with load bar and deflection bar, the latter being completely eclipsed and invisible when a single ply of the blind is deployed.
  • the subject of the invention is a blind intended to be installed in front of a bay for obscuring through light, of the type comprising a flexible panel or "canvas" secured by one of its edges to an upper roller and by its opposite edge.
  • a load bar engaged in lateral guides and movable on the one hand along a path called “go" from top to bottom from the upper part of the bay to the lower part of the bay, then from bottom to top forming a second sheet of canvas parallel to the previous one over the entire height of the bay or only partially, by raising the canvas around a deflection bar, and on the other hand according to a path called "return" opposite of the previous one , characterized in that the load bar is fixed at its ends to supports engaged in the lateral guides, which have two parallel paths connected to their lower part by a 180 ° elbow, the return bar is t placed freely on the load bar and having ends which extend beyond the outline of the fabric so that their path passes in front of blocking parts which must on the one hand immobilize said return bar as soon as
  • Figures 1 to 3 schematically illustrate, in perspective with partial section, three different positions of a blind according to the invention.
  • Figures 4 to 6 are schematic side views of a blind according to the invention in three characteristic positions.
  • Figures 7 to 9 are partial schematic views showing on the one hand the passage of the fabric from its path going from top to bottom to its path going from bottom to top and, on the other hand, the positioning of the bar of reference.
  • Figures 10 to 13 are partial schematic perspective views supplementing Figures 7 to 9.
  • Figure 14 is a partial schematic view showing the upper part of a blind according to the invention and an operating mechanism of the manual type.
  • a blind according to the invention comprises on the one hand a fixed frame composed of a horizontal upper box 1 and of two symmetrical lateral vertical uprights 2 (only one is visible in FIGS. 3 and 14) and, on the other hand, a deployable fabric 3.
  • the box 1 contains a roller 4 to which is fixed one of the edges of the fabric 3 and which is rotatably mounted in pins of known type (not shown).
  • the fabric 3 comprises two parts integral with one another, the first 31 constitutes a sun protection and is intended to filter daylight, while the second 32 is as opaque as possible in order to be able to conceal as completely as possible the bay fitted with the awning.
  • Part 32 is fixed to the roller 4
  • part 31 is fixed to a load bar 5.
  • the load bar 5 has at each of its ends a portion of smaller diameter 51 which determines a circular shoe 52 intended to be engaged in a slide (not shown) constituting a vertical guide placed inside each upright 2.
  • the load bar 5 is guided by its two ends during all its movements and, in a static situation, the blind cannot "flap" under the effect of wind or drafts.
  • the blind comprises a return bar 6 which is movable with the load bar 5 in the first part of the outward journey and the second part of the return path of the fabric 3, while it is immobilized at the lower part of the blind to play its role of fixed return.
  • the deflection bar 6 is freely placed at the lower part of the fabric 3 where it remains stable, owing to the fact that the fabric 3 forms a pocket due to the deliberately large weight of the deflection bar 6.
  • the deflection bar 6 is located as close as possible to the load bar 5 and follows the latter in its movements: during the descent of the forward path of the fabric 3 the weight of the deflection bar 6 forces it to rest against the load bar 5 and during the ascent of the return journey, it is the load bar 5 which lifts the return bar 6.
  • a link closed on itself 7 such as a chain, a cable, a cord, a strap, a toothed belt or the like, engaged on two pulleys, one located at the top uprights 2 (not shown) and the other 8 placed at the bottom of the uprights 2.
  • the pulley located at the upper part of the uprights 2 is kinematically connected to the horizontal roller 4, so that the rotation of the roller 4 causes the pulley to rotate and the corresponding displacement of the link 7.
  • the parts 51 of the load bar 5 are engaged in rings 9 integral with the link 7, so that the rotation control of the roller 4 results in the synchronous movement of the load bar 5, either to bring it down or to raise it in the direction in which the roller 4 is driven: when it is rotated in the direction corresponding to the unwinding of the fabric 3, the load bar 5 is driven downwards; when it is rotated in the direction corresponding to the winding of the fabric 3, the load bar 5 is driven upwards.
  • the invention provides that the deflection bar 6 is movable with the fabric 3, between the upper part and the lower part of the blind and remains fixed, in the lower part, when the second layer of the blind.
  • the roller 4 is rotated, which causes the links 7 to move along the down arrows F1, which move the rings 9 which drive the load bar 5 downwards, also according to the arrows F1.
  • the blocking mechanism intervenes and immobilizes the return bar 6 ( Figures 2 and 6) while the load bar 5 can, at the will of the user, be stopped in this position (a single sheet of canvas is then deployed) or driven beyond.
  • part 32 is very opaque and is intended for the complete concealment of light as possible, in particular for the night.
  • the deflection bar 6 has at its ends two crank pins 61 engaged in open half-yokes 10 which are integral with the links 7, like the rings 9, and which are suitably spaced from the rings 9, taking into account the diameters of the bars 5 and 6 and of the thickness of the fabric 3, so that the crank pins 61 are well placed in the half-yokes 10.
  • crank pins 61 stationary at the lower part of the blind when the half-yokes 10 continue their movement, like the rings 9, along the ascending strand of the links 7, according to the arrows F2.
  • the pulleys 8 are integral with a cam 11 having two notches 12 and 13 capable of receiving respectively the parts 51 of smaller diameter and the crank pins 61.
  • the cam 11 is pivotally mounted and is associated with a stop (not shown) which limits the amplitude of its pivoting.
  • crankpins 61 penetrate the notches 13 and follow the pivoting movement according to the arrows F4 (FIG. 8) until the cam 11 meets the stop which stops its pivoting (FIG. 9).
  • the links 7 can continue their movement and drive the rings 9 and the half-yokes 10 which rise according to the arrows F2, the crank pins 61 remaining blocked by the notches 13 of the cam 11 immobilized by the stop, while the parts 51 come out easily notches 12 taking into account the different orientations of the notches 12 and the notches 13.
  • the fabric 3 rises and the load bar 5 lifts the deflection bar until all action on the roller 4 and, therefore, on the links 7 is stopped.
  • Figure 14 shows that one can cause the rotation of the roller 4 and the upper pulley carrying the links 7 by means of a rod 20 connected to an oblique control rod 21 by a gimbal 22, the rod 20 being provided with 'a crank (not shown) of any known type.
