Definitions

  • the invention relates to a window covering for covering or leaving wholly or partially clear at least one window as required, comprising:
  • Such a window covering is also designated in the trade as day and night window covering, combi-pleat, dual window covering etc.
  • the window covering can be applied as required with one or more tensioning cables for a hanging of the window covering which is other than vertical.
  • the presence of an intermediate profile increases the possibilities of the present window covering compared to a more conventional window covering lacking an intermediate profile.
  • the existing window coverings of the type stated in the preamble have separate drive mechanisms and operating means. Operation of the window covering is hereby relatively complex and susceptible to malfunction. An example hereof is that the intermediate profile has to be pulled up before the lower profile is pulled up because otherwise the operating cords of the intermediate profile have an excess length and will behave uncontrollably. Another drawback of the existing dual window covering is that the construction is relatively costly.
  • the present invention has for its object to provide a dual window covering not displaying these drawbacks.
  • the invention provides for this purpose a window covering of the type stated in the preamble wherein the drive mechanisms are integrated and provided with single operating means with which both intermediate profile and lower profile can be controlled.
  • Foldable screening means can herein be arranged between intermediate profile and lower profile and/or between housing and intermediate profile. Due to integration of the drive mechanisms and the presence of single operating means, operation of the dual window covering is very simple and foolproof. This means that incorrect operation of the window covering, with the associated risk of damage, is precluded. Automatic operation of the dual window covering hereby also becomes more obvious. In the case of a manually operated dual window covering single operating means have the advantage that they are less unattractive than two separate operating devices.
  • screening means it is possible to arrange different screening means. It is thus possible for instance to arrange a light-proof fabric between housing and intermediate profile and to arrange a light-transmitting fabric between intermediate profile and lower profile. A so-called day/night window covering is thus obtained.
  • other screening means can also be applied in the window covering according to the invention, wherein slats or foil can for instance be envisaged.
  • slats or foil can for instance be envisaged.
  • Another option is to leave free the space between housing and intermediate profile and to only arrange screening means between intermediate profile and lower profile.
  • a window covering can thus be arranged which leaves clear the upper part of a window and the height of which is adjustable as desired.
  • the integrated drive mechanism comprises a central rotatable winding shaft onto which engage winding cords of two different lengths, the shorter of which engage directly onto the intermediate profile and the longer of which engage on the intermediate profile but, between the points of engagement on the intermediate profile and the winding shaft, also engage displaceably on passages connected to the lower profile.
  • the winding shaft can be provided with cord reels onto which the cords engage.
  • the lower profile will remain in a stationary position.
  • the long cords are unwound further and this additional cord length is required for displacement of the intermediate profile relative to the lower profile.
  • the total distance from housing to intermediate profile via lower profile in any case becomes increasingly longer as the intermediate profile is raised.
  • An end position is reached when the long winding cords are fully unwound or when the intermediate profile reaches the housing.
  • the winding shaft can then no longer be rotated in the rotation direction applicable up to that point. Adjustment or full raising of the window covering is solely possible by rotation of the winding shaft in the only possible rotation direction still remaining.
  • the end position in this second rotation direction is obtained when the lower profile and intermediate profile lie against the housing.
  • the integrated drive mechanism comprises a central rotatable winding shaft onto which engage winding cords which also engage onto the lower profile and, between the points of engagement on respectively the winding shaft and the lower profile, respectively engage displaceably on a passage connected to the intermediate profile and a passage connected to the housing.
  • the winding shaft can herein also be provided with cable reels onto which the cords engage.
  • the intermediate profile can be raised at any random position of the lower profile.
  • the intermediate profile is only raised when the lower profile is situated in the extreme position.
  • the advantage of the first embodiment compared to the second described embodiment is that the winding shaft has to make fewer revolutions for a corresponding displacement of the profiles.
  • the operating means can be formed by an endless operating cord. It is very easily possible using the endless operating cord to cause the winding shaft to rotate in the desired direction. Instead of an endless operating cord it is possible to opt for another operating element, such as for instance a rotating rod. Another option is to cause the winding shaft to rotate by motor, wherein operation of the motor can for instance take place remotely.
  • the advantage in this embodiment is that only one motor is required as compared to the two motors in the dual window covering of the prior art. Since an operating motor must have relatively great power combined with a small volume, these motors are very costly. A dual window covering with only one operating motor is therefore considerably cheaper than a prior art motor-driven dual window covering.
  • Figure 1 shows a first embodiment of a window covering 1 with a housing 2 in which is accommodated a drive mechanism 3.
  • Window covering 1 is further provided with an intermediate profile 4 and a lower profile 5.
  • a pleated curtain 6 is arranged between housing 2 and intermediate profile 4 and a pleated curtain 7 is arranged between intermediate profile 4 and lower profile 5.
  • Drive mechanism 3 is provided with a winding shaft 8 on which are arranged cord reels 9, 10, 11, 12.
  • An endless operating cord 13 likewise engages on winding shaft 8 so that winding shaft 8 is rotatable with the cord 13.
  • the two outer cord reels 9, 12 are provided respectively with cords 14, 15 which are fixedly connected on one side to cord reels 9, 12.
  • the other end of cords 14, 15 is connected by means of coupling elements 16, 17 to intermediate profile 4.
  • Cords 14, 15 run from cord reels 9, 12 through intermediate profile 4 and through a passage in lower profile 5 before engaging on the underside of intermediate profile 4.
  • the passage in lower profile 5 consists of two openings 18 in lower profile 5.
  • the central cord reels 10, 11 are provided respectively with cords 19, 20 which engage directly onto the top part of intermediate profile 4.
  • Figure 2 shows the window covering 1 in a situation where intermediate profile 4 and lower profile 5 have been lowered so far that cords 19, 20 are fully unwound.
  • the pleated curtain 6 lying between housing 2 and intermediate profile 4 is now fully lowered.
  • Figure 3 shows the window covering 1 in a position in which the rotation of winding shaft 8 has been continued so far that winding cords 14, 15 are fully unwound, this being clearly visible from the reels 9, 12 with no cord wound around them.
  • Winding shaft 8 has resulted in the cords 19, 20 being fully rewound onto cord reels 10, 11.
  • Intermediate profile 4 is therefore fully raised such that pleated curtain 6 is folded up again.
  • FIG 4 shows a window covering 21 wherein the components corresponding with the components as shown in figures 1-3 are designated with the same reference numerals.
  • Winding shaft 8 is provided with only two cord reels 22, 23 onto which are wound cords 24, 25 respectively. As seen from cord reels 22, 23 winding cords 24, 25 are first carried through intermediate profile 4 and then fed through housing 2, whereafter the cords finally engage on lower profile 5.
  • cords 24, 25 When cords 24, 25 are subsequently wound onto cord reels 22, 23 a position results for instance as shown in figure 6.
  • Cords 24, 25 choose the path of least resistance and will first raise intermediate profile 5 to a position in which the upper pleated curtain 6 is fully folded up.
  • the lower pleated curtain 7 will hereby come to lie in an unfolded state.
  • winding shaft 8 is further rotated from the position shown in this figure, the lower profile 5 will then also be raised.
