Definitions

  • the invention relates to a locking device for the cords of a sun-blind or the like provided with an upper beam and one or more webs from sun-blinding material connected thereto, preferably material folded in a zigzag line, in which the cords are introduced through holes in the upper beam, extend through the inner space of the upper beam to one end of the upper beam and therefrom to the outside for opening or closing the sun-blind, the locking device comprising a U-shaped portion having legs between which a tumbler having a pivot shaft near its upper end is pivotally mounted.
  • Such a sun-blind is known from NL-A 7307075 laid out to public inspection.
  • an endstop is provided, one of said endstops is provided with a hole for introducing a number of cords.
  • said cords sometimes as much as nine pieces, are connected to one single cord by means of which the sun-blind may be pulled up and dropped.
  • the fastening of said cord is carried out by means of a toggle affixed to the window- frame.
  • a need of a locking device exists which automatically locks the cords when they are not pulled anymore.
  • Such automatically operating locking devices are known indeed for sun-blinds provided with tilting lamellae. These blinds have a rather robust upper beam and the locking device may be built in therein, or affixed at its outside, see US-A-2.731.111.
  • an automatically operating cord locking device being small such that it may be built in at the location of the one endstop or in a little defacing way against the external side of the one end of the upper beam.
  • the locking device consist of a U-shaped portion having a flat bottom and legs, which portion is provided at its one end with a cross-plate in which an aperture for a number of cords is provided and of a tumbler having a pivot shaft near its upper end, which pivot shaft is journalled in the legs of the U-shaped portion near the tops of the legs, in which in its lowermost position the tumbler substantially fills up the space between the legs and the bottom under the pivot axis and the lower edge of the tumbler is spaced from the bottom by a distance smallerthan the thickness of the cords, which should extend between the bottom and the lower edge, said tumbler is loaded by a member which is slidable in the cross-plate in vertical direction, carrying a flange or the like, the free end of which cooperates with the adjacent face of the tumbler, whereby in the portion of the slidable member, which is lying in the cross-plate an aperture for the cords is provided substantially coinciding with the aperture in the cross-plate, whereby the
  • the cords can pass below the tumbler to drop the biind. At horizontal displacement of the cords in the opposite direction the cords are urging the slidable member and thus the tumbler downwards, so that the cords are maintained in each desired position of the blind.
  • the locking device according to the invention is not only suitable for sun-blinds in zigzag lines. Also for so-called “Venetian blinds” it can be used, or for other foldable or windable screens which may be closed or opened by means of cords.
  • the locking device according to said US-A-2,731,111 comprises also a U-shaped portion having legs between which a tumbler having a pivot shaft near its ' upper end is mounted.
  • this device is not suitable for a sun-blind or the like with a very modest upper beam.
  • the upper beam comprising two parts is referenced by 1 and 2.
  • the external beam 1 consists in the known way of aluminium and the inner beam 2 in the known way of plastic.
  • the web folded in a zigzag line is referenced by 3.
  • the upper end of said web 3 is fastened to the inner beam 2.
  • a plastic endstop as shown in the Dutch Patent Application 7307075.
  • a plastic endstop is provided having an inlet hole for the cords indicated by 4.
  • the locking device according to the invention substituting the known endstop consists of a U-shaped portion having a bottom 5 and upstanding walls 6. Both the bottom 5 and the walls 6 are flat and are perpendicular to each other. At the right hand end a cross-plate 7 is provided in which an aperture 8 for the cords 4 is present.
  • a tumbler 9 is arranged being connected pivotably to the legs 6 at its upper end, for example this may be implemented by a thin shaft 10 inserted through holes in the legs 6 and through a through-going hole in the tumbler 9.
  • the tumbler 9 fits between the legs 6 and may be moved freely with respect to them.
  • the lower edge of the tumbler 9 is slightly spaced from the upper side of the bottom 5. Said distance is smaller than the diameter of the cords 4 for which the locking device is intended. This means that the tumbler 9 inclines with respect to the vertical plane, when cords 4 are at the upper side of the bottom 5.
  • This member 14 consists of a rectangular vertical portion 14a and a rectangular horizontal flange 14b, perpendicular to each other.
  • the member 14 is preferably made as a unit from stainless steel.
  • the vertical portion 14a is slidably received in a slot 15 in the thick cross-plate 7.
  • an inlet hole for the cords 4 is provided.
  • This inlet hole corresponds completely to the aperture 8 in the cross-plate 7 with a bottom part 8a, inclining upwards to the left, but is turned over 180°. This means that the bottom part 8b of the inlet hole in the portion 14a is inclining upwards to the right.
  • the cords 4 are in the valley between the slopes 8a and 8b.
  • the cords in fig. 6 are moved to the left, they do not press longer on the slope 8b of the member 14. This member 14 is made free. Moreover, the cords 4 are moving upwards along the slope 8a and swing the tumbler 9 away from the cords 4. The blind can be dropped.
  • the U-shaped portion 5, 6 and the cross-plate 7 may be manufactured integrally from plastics material.
