Definitions

  • a cord connecting device for Venetian blinds and the like is provided.
  • the invention relates to a cord connecting device for pull cords for Venetian blinds and the like, comprising a hollow body in two parts with a first opening consisting of part openings m each part of the body, behind which cord ends supplied with knots are retained.
  • Traditional cord connecting devices consist of a knot on the pull cords which are hidden m a hollow shell. Following accidents where children have been strangulated after having put their necks m the noose created by such traditional cord connecting devices, types have been developed where the cords are connected by the hollow shell itself. It is desired that a cord connecting device shall separate by pulling, but it is difficult to obtain a suitable compromise between the force with which the shell shall stay closed with a view to normal use, and the force which shall cause a separation. In particular where it is desired to let a mutual pull cord come from the cord connecting device the requirements are contradictory.
  • each body part at a distance from the first opening has means directed towards each other, each of which carry slits for retaining the knot-shaped ends of the pull cords, which means hold the hollow body together by interlocking, m that the influence of the pull cords on the part openings separate the interlocking.
  • the knots are held inside the cord connecting device so that no forces are transmitted to the shell during normal use. Not until it is attempted to separate the cords, which will occur when something is wedged, will forces be created in the shell parts whereby they separate and the knots are liberated.
  • An advantageous embodiment is particular in that a further cord is taken through a second opening m such a manner that it holds together the the means directed towards each other, so that a pull m the further cord causes the two parts to be held against each other with an increased force.
  • activation by pulling the pull cord causes a force which dicrectly holds the two parts together, the stronger, the stronger the pull in the pull cord, but the possibility of separation and the force required is not influenced thereby.
  • a further advantageous embodiment is particular m that the means directed towards each other are plate shaped, and that holes m the plates are m register when assembled, and m that the slits are disposed between the edges of the plates and the insides of the parts.
  • This embodiment is a practical solution, which only requires that the further cord is taken through the holes and is supplied with a knot on the upper side of the two plates.
  • Fig. 1 shows two half parts of a cord connecting device according to an embodiment of the invention
  • Fig. 2 shows the two half parts with cords during assembly
  • Fig. 3 shows the two half parts w th cords immediately before assembly
  • Fig. 4 shows a cord connection device when assembled.
  • a cord connecting device which consists of two hollow half shells 1 and 2 which leave a hole at the upper and lower ends, through which cords may pass to the inside of the cord connecting device.
  • each shell part On the inner side each shell part has a plate-shaped protrusion 3, 4 which are displaced with respect to each other and parallel when assembled.
  • Two further plate parts have been provided above the plate 3, and the the lowermost has a depression on its upper side which cooperates with a corresponding projection on the lower side of the plate 4, so that the two half shells are held to become one by means of a snap action.
  • This snap action connection may be solved m various ways, only must the force required for separation be held suitably low.
  • each plate-shaped protrusion On either side of each plate-shaped protrusion there are slits 5, 7, 6, 8 with a width which is only slightly larger than the thickness of a pull cord.
  • holes 9, 10 which are only slightly larger than a thicker joint cord which may exit from the lower hole. These holes do not register when assembled, but are so that they are nearer the outer surface of eacn shell part 1, 2.
  • Fig. 2 it is shown how cords are mounted m the cord connecting device according to the present embodiment of the invention.
  • the two pull cords 11 and 12 are supplied with knots, whereafter the cords are pushed into the slits 5 and 8 with the knots below the plates 3 and 4.
  • any pull m the cord is absorbed in the central part of the cord connecting device rather than m the shell parts.
  • a further, thicker cord 15 is taken through the holes 9 and 10 m the plate-shaped protrusions 3 and 4, and subsequently a knot 16 is formed at the upper side of the 4

Abstract

La présente invention concerne un dispositif de raccordement de cordon se composant d'un corps creux en deux parties (1, 2). Ce corps comporte des orifices pour des cordons (11, 12) se terminant par un noeud. Le corps doit s'ouvrir en deux en cas de traction en sens opposés sur les cordons. Cette traction s'oppose au maintien solidaire, même avec un faible effort de saisie. L'invention présente une efficacité accrue en ce que la fixation des noeuds ne se fait pas juste à l'intérieur des coques du corps, mais près de ses parties centrales (3, 4).
