Definitions

  • the invention relates to a roller blind with training features according to the preamble of claim 1.
  • Such a roller blind is known from DE-AS 23 39 170, in which a winding shaft with its ends rotatably mounted on fixed bearing journals can be coupled at least at one end to a drive member and has at least one roller body which acts as a locking member and which in the rolling direction of the Curtain-loaded winding shaft locked with the journal.
  • the bearing journal can be fastened on both ends of the winding shaft with a holder in a rotationally fixed manner to a wall, ceiling or the like, the holder engaging in a slot arranged on the outer end face of the bearing journal.
  • a curtain is in different blind positions can be locked.
  • the locking member consists of a coil spring, which is effective in the manner of a slip clutch and fixes the curtain by friction with a sleeve.
  • so-called spring roller blinds are known in a large variety, which have locking elements made of pawls which are arranged so as to be movable radially to the roller blind axis and which interact with fixed abutments on the winding shaft. Due to the radially movable articulation of the pawls, a freewheel is achieved when the roller blind shaft rotates quickly, so that the pawls only come into contact with the abutment due to their own weight when the roller blind shaft rotates slowly and cause a blockage between the roller blind shaft and the fixed pin.
  • the parts of the mechanics for actuating and blocking the curtain can be made of metal or a suitable plastic.
  • the curtain is locked without spring elements at any height by positive locking. This locking takes place automatically through the curtain weight and is reliable. It can only be unlocked by actuating the drive element.
  • Claims 2 to 8 contain advantageous training features.
  • the bearing pin 5 can be fastened to a ceiling, a wall or the like by means of a holder 4.
  • This wall bracket 4 engages with a rectangular profile in a slot on the end face of the journal 5 and thus secures it against rotation.
  • An outer sleeve 1 is rotatably mounted on a cylindrical outer surface of the bearing journal 5.
  • a drive member 6 is rotatably mounted on a cylindrical outer surface of the journal 5, which can be rotated, for example, by a ball chain or the like.
  • the outer sleeve 1 is formed with a sleeve extension 3 arranged within a cup-shaped bottom configuration of the outer sleeve 1, which sleeve extension 3 fits into a sleeve extension 9 of the Bearing pin 5 protrudes.
  • roller bodies 2 are arranged in pairs, which act as a locking member.
  • the outer lateral surface of the sleeve extension 3 is formed eccentrically to the central axis of the bearing body in the area of the recesses in which the rolling elements 2 are arranged in pairs, so that there is a distance between this outer lateral surface and the inner lateral surface that is smaller than the diameter of the rolling element 2.
  • the sleeve extension 3 and the sleeve extension 9 can be jammed by one or more of the rolling elements 2.
  • An opening element 8 extends between the pair of rolling elements 2, these opening elements being finger-shaped and arranged on a ring. This ring is rotatably arranged on the journal 5 and coupled to the drive member 6 by a planetary gear 7.
  • a plurality of roller-like planet gears are each arranged in recesses in the bearing journal 5 and engage at one end with their toothing in an internal toothing of the drive member and with their other end in an internal toothing of the ring of the opening elements 8.
  • a rotation of the drive member leads to a rotation of the opening elements 8 engaging between the rolling bodies 2, so that they are pressed out of their locked position and release a rotational movement between the sleeve extension 3 and the sleeve extension 9.
  • the torque exerted in the opposite direction by the curtain weight on the outer sleeve 1 leads to a jamming of the sleeve shoulder 3 with the sleeve shoulder 9 by the rolling elements 2 and thus to a locking of the outer sleeve 1 with the bearing pin 5.
  • the outer sleeve 1 is rotationally fixed in a manner known per se inserted into the tube end of a winding shaft, not shown in the drawing.
  • the angle of rotation of the opening elements 8 is limited in that the opening elements 8 have on the inside a wedge spring 10 running in the axial direction, each of which engages in a substantially wider axial groove 11 on the outer jacket of the sleeve extension 3.
