Definitions

  • This specification relates to a limit stop device for the opening of sun curtains.
  • the sun curtains are wound on a roller secured to a wall and which is caused to rotate in one direction or the opposite direction to unwind and re-wind the curtain.
  • the end of the curtain is secured to a frontal rod supported by two articulated arms fitted with springs and which tend elastically to move the rod away from his housing applied on the wall in order to keep the curtain constantly stretched.
  • the curtain When the arms are extended to their maximum limit, and if the user is not careful, in continuing to turn the roller, the curtain will first loosen and may, immediately, after, rewind itself on the roller in the opposite direction and this may damage the curtain, and prevent a correct gripping of the frontal rod on the housing.
  • the purpose of the invention is to provide a device apt to interrupt the unwinding of the curtain from the roller when the supporting arms of the frontal rod have reached their maximum extent of opening, so that even a distracted user will not be able to unwind the curtain more than necessary or rewind it in the opposite direction, which would damage both the curtain and the mechanism.
  • the device which exploit's the tendency of sun curtains to open under the action of sprung arms, is characterized by a ratchet mechanism fitted in the roller of the curtain; said mechanism consists of a small cylinder applied in the cavity of the roller and which is pro­vided with at least two fixed teeth projecting toward the axis of the cylinder itself and by a pin, rotatable within said cylinder, provided with sprung teeth apt to engage or not with the fixed teeth of the cylinder, depending on their rotating direction.
  • the mechanism is conceived so that by turning the pin in one direction, the oscillating teeth disengage from those of the cylinder, thereby enabling, thanks to the action exerted by the frontal rod, the opening by snap action of the curtain, which, in this way, cannot proceed beyond the maximum opening position, while turning the pin in the opposite direc­tion, the oscillating teeth engage with the small cylinder to re-wind the curtain.
  • Fig. 1 the sun curtain 1 is wound on a roller 2, inserted in a housing 3. End 4 of the curtain is secured to a cross frontal bar 5, sus­tained at both its ends, by arms 6 and 7 which tend to move away, elastically, frontal bar 5 from housing 3 by means of spring 8.
  • Device 10 consists of a cylinder 12 which, in the case illustrated in Fig. 3, is provided internally with three teeth 14 of rectan­gular cross section, integral with cylinder 12.
  • the center part of cylinder 12 is provided with a port 18 for a pin 20 restrained with a retaining ring inside the roll.
  • pin 20 With pin 20 are integral a flange 22 inside cylinder 12 and an external flange 24 which practically is a closing cap for the cylinder itself. Flanges 22 and 24 retain, in the case shown in the drawings, three pins 26 on each of which is mounted an oscillating tooth 30 fitted with a spring 32 which tends to urge each tooth 30 elastically toward the exterior.
  • the oscillating teeth 30 have a substantially lenticular shaped cross section and a curved back 33. Teeth 30 are provided, at their free end, with an edge 34 apt to engage with the base of said rectangular teeth 14 crossing the internal surface 35 of cylinder 12.
  • the cylinder is secured in the hollow of roller 2 by shrinkage.
  • pin 20 terminates with a square end on which a toothed wheel (not shown) is secured, said wheel being moved by an endless screw housed in box 50 and which is integral with a shaft 52 provided with an eyelet 54 to which can be applied a handle bar, apt to be rotated in one direction or the other by the user to unwind or rewind the curtain.
  • the length of curtain wound on the roller can thus be limited to the necessary extent, thereby affording a saving of cloth.
