Definitions

  • the present invention relates to a blind of the awning type, that is to say comprising a fabric stretched over a load bar and rolled up on a cylinder.
  • Articulated arms are connected to the load bar so that by unwinding the canvas from the cylinder, the load bar moves away from the cylinder and deploys the canvas. Likewise, by winding the canvas on the cylinder, the arms fold up because the canvas pulls on the load bar.
  • the first solution is relatively expensive to build and has drawbacks as regards the size and the aesthetics of the assembly.
  • the second solution is the one that has been most often adopted in recent years for its qualities of simplicity and cost price.
  • a banner is, by nature, large since it must equip very large bays such as shop windows, restaurant terraces, etc., so that it constitutes a real sail sensitive to the effects of wind. It is very common to see fabrics inflate following eddies of wind and this results in stressing the arms and the load bar according to efforts sometimes significant enough to damage the entire frame of the blind.
  • the present invention also relates to a blind of this type, since it provides for certain embodiments which make use of jacks. But it is characterized by a particular organization of such jacks because their action must be synchronized with that of a stop member for the canvas winding cylinder and none of these provisions is described in this German patent.
  • the jacks provided by the German patent act in the direction of a push on the arms to deploy the blind and that they have no action to keep the fabric stretched. It is the canvas itself that holds the arms, so that the cylinders are only "gas springs".
  • the present invention provides a new solution to the problem of control and stability of a banner, even very large and / or subjected to strong stresses of the wind. It also provides particular advantages with regard to the operation of awnings of the awning type.
  • the subject of the invention is a blind of the awning type comprising, on the one hand, a frame made up of articulated arms, a load bar, possibly a so-called “motor” mechanism for the relative movement of these elements and a rotary cylinder in bearings and on the other hand a fabric stretched between the load bar and the cylinder on which it can be wound, characterized in that each arm is provided with a two-point locking mechanism located on either side of the articulation of the two half-arms that make up each arm in order to immobilize them permanently in their two possible directions of movement when the locking mechanism is itself immobile, while the cylinder is of the type comprising a member such as a spring intended to urge it permanently in its direction of rotation corresponding to the winding of the fabric and is associated with a stop member: from the cylinder rotation, this member d the stop being capable of occupying an active position and an inactive position in which it is neutralized.
  • a blind according to the invention comprises on the one hand an armature composed of articulated arms 1 and 2, of a load bar 3, of a cylinder 4 rotatably mounted in bearings 5 and on the other hand, a fabric 6 stretched between the load bar 3 and the cylinder 4 on which it can be wound.
  • Each arm is made up, as is known per se, of two half-arms 1a, 1b and 2a, 2b respectively hinged together.
  • the half-arms 1a and 2a are articulated on fixed supports 7 and 8 while the half-arms 16 and 2b are articulated on the load bar 3 by pivots 9 and 10.
  • Each arm 1 and 2 is provided with a locking mechanism, here a double-acting cylinder, respectively 11 and 12, which has two points of application 13 and 14 on the one hand, 15 and 16 on the other hand located from on either side of the joints 17 for the arm 1 and 18 for the arm 2.
  • a locking mechanism here a double-acting cylinder, respectively 11 and 12
  • the cylinder 4 is equipped, as is known per se, with a spring mechanism (not visible in the drawing) by which it is permanently stressed in its direction of rotation corresponding to the winding of the fabric 6.
  • the cylinder 4 is integral with a drum 19 opposite which there is a movable shoe 20 capable of being applied more or less energetically costre this drum 19 to oppose the rotation of the cylinder 4 and, to the reverse, to be moved away from the drum 19 to release the rotation of the cylinder 4.
  • the actuators 11 and 12 are connected to a source of pressurized fluid (not shown) by means of a control unit 21 to which a fluid supply line 22 ends and from which two lines 23 and 24 leave, respectively leading to the cylinders 11 and 12.
  • the mechanism placed in the housing 27 occupies, in synchronism with the jacks 11 and 12, a position corresponding to the more or less energetic action of the shoe 20 against the drum 19 so that the cylinder 4 tends to be immobilized.
  • this immobilization of all the movable elements of the blind ensures the stability of the fabric in all circumstances thanks to the combined action of the pad 20 against the drum 19 which creates an easily calibrated force during construction.
  • the moving fluid acts on the mechanism placed in the housing 27 to place the shoe 20 in a position away from the drum 19, so that the latter and the cylinder 4 of which it is integral can rotate freely, what they do under the effect of the spring mechanism which permanently urges the cylinder 4, these arrangements having the result of automatically winding the fabric 6 on the cylinder 4 as the load bar 3 rises, that is to say as long as the rods 11b-12b are in motion.
  • the user stops acting on the button on the control unit 21, which has the immediate effect of immobilizing the rods 11b-12b of the cylinders 11-12, the arms 1-2 and the load bar 3.
  • the cylinder 4 for its part, undergoes an immobilization force whose value is established, for example, by providing a spring which acts permanently on the shoe 20 and which is not neutralized by compression, temporarily, only by the pressurized fluid.
  • the arms 1 and 2 are completely folded up like standard arms because the jacks 11 and 12 are placed so that they do not oppose their complete folding back.
  • the jacks 11 and 12 can be accommodated in the profile of the arms when the lateral movement of the jacks and the rods relative to the arms is provided.
  • stop member constituted by the assembly 19-20 associated with the cylinder 4 comprises a mechanism synchronized with at least one of those which equip the arms 1 and 2.
  • these mechanisms are constituted by jacks 11 and 12.
  • Synchronism can be obtained by hydraulic connection according to which the shoe 20 is constantly and automatically biased in the stopped position of the drum 19 while it is placed in the inactive position as soon as the pressurized fluid is set in motion, whether this involves extending or folding the arms 1 and 2.
  • the pressurized fluid lines extend from a source to the jacks passing through the control unit comprising valves which control the flow of the pressurized fluid.
  • each arm consists of a cylinder of the single-acting type, that is to say comprising only one fluid line, this cylinder comprising a spring permanently urging the rod of the jack in the direction opposite to that given by the fluid, this spring advantageously consisting of a compressed fluid such as air, nitrogen or the like.
  • This arrangement simplifies the construction of the blind and eliminates one of the pipes, either 23 or 24.
  • the pressurized fluid is preferably constituted by an incompressible liquid such as oil, so that the compressed fluid such as gas, can be elastic without causing the drawbacks of the blinds known and recalled in the preamble hereto.
  • the set of fluids used is incomprehensible and makes the set inelastic only up to a certain threshold beyond which the arms become elastically deformable in the direction allowing the play of the canvas in the manner of a sail and its return to its previous tension.
