Definitions

  • the subject of the invention is a roller blind equipped with multiple stop means at several points spaced along its unwinding and winding stroke.
  • a roller blind comprises a free rolling cylinder rotating around its geometric axis, an internal rod mounted coaxially with this cylinder with a first internal end and a second external end immobilized in rotation, a means locked in rotation with one end of the cylinder. winding to rotate around the inner rod, an inner return spring which surrounds the latter and which is fixed on the one hand to the first end of said rod and, on the other hand, to the hub.
  • the hub comprises an outer ring with central opening coaxial with the cylinder and the inner rod; in this ring are pierced a plurality of circumferentially spaced radial holes, each opening into the central opening and each containing a ball.
  • This crown is integral in rotation with the winding cylinder and it freely contains a cage having at its periphery a half-housing capable of partially receiving any ball of any radial hole.
  • the cage contains a ring which is locked in rotation on the inner rod and which carries a stop means leaving an angular movement of limited amplitude of the cage relative to this ring.
  • a thrust means penetrating into the half-housing is housed in the thickness of the cage.
  • This means comprises a piston which is pushed by a spring against a bearing surface provided on the ring and which is stopped in rotation during said angular movement.
  • this means In a first position of the thrust means permitted by the stop means, this means is engaged sufficiently in the half-housing to prevent a ball from entering it. In a second position of the thrust means permitted by the stop means, this means is withdrawn sufficiently from the housing half 7 so that a ball can partially penetrate it.
  • the balls rotate with the crown and are prevented by centrifugal force from entering the half-housing.
  • the stop means occupies its first position and the first ball which arrives in front of the half-housing engages in it partially and opposes any winding. additional awning.
  • the piston of the thrust means is stopped by the bearing surface of the ring and the thrust means enters the half-housing and drives out the ball. It becomes possible to let the blind roll up at its normal speed during which the centrifugal force prevents the balls from entering the half-housing.
  • the blind can be immobilized at any point in its travel after having allowed it to rise slowly up to a fifth of a turn.
  • the blind shown comprises a winding cylinder 1, at the periphery of which is attached a flexible sheet 2, and which is mounted to rotate freely about its geometric axis 3, in a known manner.
  • the cylinder 1 contains an inner coaxial rod 4 having a first inner end 5 free relative to the winding cylinder 1 and to which is fixed one end of a spring 6 for winding the flexible sheet 2.
  • the winding cylinder 1 is provided with a hub 7 with which it is locked in rotation.
  • This hub 7 is freely traversed by the inner rod 4; it ends with an outer end portion 8 with the aid of which it is immobilized in rotation.
  • the hub 7 has concentrically with the inner rod 4 an outer ring 9 having a central opening 10 which contains a cage 11.
  • Several radial holes 12 (five in this example) circumferentially equidistant are drilled in the annular wall of the ring 9 to open into the central opening 10.
  • Each radial hole 12 freely contains a ball 13.
  • a half-housing 14 arranged vertically, open upwards, capable of partially containing, approximately half, the any of the balls 13.
  • the cage 11 has a central hole 15 in which a ring 16 which is locked in rotation on the inner rod 4 is freely engaged by means of a diametrical group 17.
  • the latter has an end 17A which is external to the ring 16 and which extends inside.
  • a recess 18 dug in the cage 11 from the inner face of the central hole 15.
  • the recess 18 has, between two radial end faces 18A, 18B, an extension in circumferential direction which is greater than the diameter of the pin 17, in a direction which will be specified later.
  • a blind hole 19 is drilled obliquely in the cage 11 in the direction of the half-housing 14, so as to partially pass through the central hole 15.
  • the ring 16 has, at its periphery, a recess 20 which makes it appear at inside the blind hole 19 a radial bearing surface 21.
  • the blind hole 19 stops before reaching the half-housing 14 and is followed by a coaxial hole 22 of smaller diameter which opens into this half-housing 14.
  • a piston 23 is slidably mounted in the hole 19; it has a rod 24 which enters the hole 22 and which is just flush with the half-housing 14 when the piston 23 is pushed against the bearing surface 21 under the pressure of a compression spring 25 which surrounds the piston rod 24.
  • the winding spring 6 tends to rotate the winding cylinder 1 and the outer ring 9 counterclockwise indicated by an arrow F 1 in Figures 3 and 5
  • the end part 17A of the pin 17 is applied against an end face 18A of the recess 18 and it is distant from the opposite end face 18B.
  • the latter is arranged so that when the winding cylinder 1 and the outer ring 9 are rotated slightly clockwise F 2 by pulling on the flexible sheet 2, a relative rotation occurs in this direction around the fixed ring 16 until the end portion 17A of the pin 17 is encountered by the end face 18B.
  • the blind of the invention operates as follows.
  • the mechanism can be in the locked state visible in FIG. 3 or in the unlocked state visible in FIG. 5. If the flexible sheet 2 is pulled in the clockwise F 2 of the course, when a ball 13 is engaged in the half-housing 14 (locked state) the limited relative angular movement described above occurs and the ball 13 is driven from the half-housing 14 by the piston rod 24. During normal operation, the centrifugal force drives the balls 13 outward from the holes 12; more the piston rod 24 is engaged in the half-housing 14 and would oppose their entry therein.
  • the hub 7 has a widening in diameter relative to the winding cylinder 1 in order to make the outer ring appear. opposes the loss of the balls 13.
