Definitions

  • the present invention relates to a ladder cord assembly for a Venetian blind, including a ladder cord and a connector, the connector being adapted for securing to a bottom rail of a Venetian blind.
  • the present invention provides a Ladder cord assembly for a Venetian blind, including a ladder cord and a connector, the connector having a first portion for securing to a bottom rail of a Venetian blind and a second portion that is permanently connected to the ladder cord.
  • a ladder cord assembly can be easily positioned in a Venetian blind assembly machine and can be readily connected with a bottom rail; either prior to or, after assembling of the slats has been completed.
  • the connector can be permanently attached to the ladder cord at any stage of the production prior to the insertion of slats, while the ladder cords can still be manipulated with every available freedom.
  • the connector comprises a groove for receiving an end portion of the ladder cord. Such a groove will enhance the exact positioning of the ladder cord ends in respect of the connector.
  • the connector further includes a slot for receiving a lift cord.
  • a slot for receiving a lift cord.
  • the slot is positioned in the connector such that its entrance becomes closed once the connector is inserted in an opening in a bottom rail. Such an arrangement would prevent the lift cord from accidentally becoming detached.
  • the ladder cord assembly according to the invention, if the first portion of the connector is adapted to be releasably secured to a bottom rail. This makes it possible to replace damaged or faulty ladder cords during the life of the Venetian blind.
  • the second portion is fused to the ladder cord.
  • the connector is of polycarbonate and the ladder cord of polyester.
  • the first portion 19 has been shaped to be flexible with a first slot 23, a second slot 25, a third slot 27 and a fourth slot 29.
  • the first portion 19 is further provided with detent ridges 31, 33 to provide, together with the first to fourth slots 23, 25, 27, 29, a snap-fit connection with an opening in a bottom rail (to be described in more detail below).
  • Figure 2 shows the ladder cord assembly 1 in a position ready to be affixed to a bottom rail 34 together with a lift cord 35.
  • the lift cord 35 as seen in Figure 2 has a knot 37 at its end. While the lift cord 35 can pass through the second slot 25, the knot 37 will be retained within the cavity 32 (see Figure 1).
  • the bottom rail 34 further is provided with an opening 39 into which the first portion 19 of the connector 17 can be snap-fitted and retained afterwards.
  • FIG 3 shows the resulting assembly after the elements shown in Figure 2 have been connected to one another.
  • the bottom rail 34 can be raised by the lift cord 35 to collect the slats (not shown) each resting on one of the cross rungs 9 of the ladder cord 3.
  • these same slats can be tilted for controlling light admittance, when the bottom rail 34 is in a lowered position.
  • slats are deleted for clarity, it should be understood that in a Venetian blind, using the ladder cord assembly, each cross rung 9 (and 11) would be supporting a slat. Such a Venetian blind would also make use of at least two ladder cord assemblies 1 according to the invention.
  • Figures 4A, 4B and 4C are bottom, side, and end elevations of a slightly modified embodiment of connector 117. Like the connector shown in Figure 1, it has a first portion 119 for securing to a bottom rail of a Venetian blind (as described and shown in relation to the first embodiment) and a second portion 121 for receiving each of the opposite ladder side cord ends (not shown) in a permanently affixed manner in grooves 106, 108 respectively.
  • the permanent fixation is again, preferably, a fusion between a polycarbonate material of the connector 117 and a polyester material of the ladder cord (not shown).
  • the first portion 119 has been shaped to be flexible with a first slot 127 and a second slot 129.
  • a third slot 125 is provided to allow entrance of a lift cord (not shown, but similar to lift cord 35 of Fig. 2) to pass into a cavity 132.
  • a knot, or beaded end, of the lift cord is adapted to be retained within a cavity 132.
  • the first portion 119 is further provided with detent ridges 131, 133 to provide, together with the first and second slots 127, 129 a snap-fit connection with an opening in a bottom rail (as already described above in relation to the first embodiment).
  • the detent ridges 131,133 are rendered more flexible by being formed on arms 140, 142 that are separated from the body of the first portion 119 by spaces 141, 143.
  • a perspective view from above of the modified connector 117 on a somewhat reduced scale is illustrated in Figure 5.
