Definitions

  • the invention relates to an insect curtain, comprising a number of partially overlapping, vertical strips of insect screen and, at the top side of the curtain, means for supporting these strips.
  • Such insect curtain is, for instance, shown in Benelux trademark registration No. 26972-00, published in September 1996.
  • Such insect curtains intended for being fitted in a door frame, have in a short time proved to be extremely successful, as they function much better than the old-fashioned insect curtains consisting of narrow, non-overlapping plastic strips.
  • the cost price can be lower than that of roller screen doors which have been available on the market since a couple of years, consisting of an insect screen which can be unrolled horizontally and which is wound on a vertical rod mounted on a door post and containing a spring motor, through which the screen, after having been unlocked from an opposite door post, automatically rewinds on the rod.
  • a drawback of the above-mentioned insect curtain is that it closes off the door opening also during often relatively long periods in a year when no insects are present and also when the door is closed. Under such circumstances, the curtain obstructs the passage and reduces the incidence of light.
  • the object of the invention is to provide a solution to this problem and to that end, it is characterized in that the means that support the strips of insect screen comprise at least one elongated shaft bearing-mounted for rotation, and means for causing said shaft or shafts to rotate so as to be able to wind the strips of insect screen on the shaft or shafts.
  • these shafts are preferably intercoupled at one of their ends, for instance by means of gears, so that one drive member for the roll-up mechanism may suffice.
  • guide means arranged parallel to the elongated shaft or shafts and intended to guide the strips of insect screen at the top side of the insect curtain along the lintel of a door frame.
  • the above-mentioned problem is solved in an elegant manner, because the insect curtain, when not in use, can readily be rolled up at the top side of the door frame.
  • a chain or cord operated mechanism as known for use with roller curtains can, for instance, be applied.
  • Such chain roll-up mechanism is, for instance, known from WO 96/07007.
  • reference numeral 1 designates a door post, along the lintel of which the suspension system of the insect curtain 2 according to the invention is mounted.
  • the insect curtain 2 comprises an elongated shaft, hereinbelow to be referred to as rolling stick 3, around which strips 4 of insect screen have been wound. These strips in each case partially overlap each other, as shown in the Figure, to guarantee a proper seal against insects.
  • the rolling stick 3 has its two ends rotatably bearing-mounted in the supports 5 and 5' respectively, mounted on the frame 1.
  • a roll-up mechanism 7 which is known per se and driven by a chain 6. It is also possible to use a cord-driven roll-up mechanism, known per se.
  • guide means 8 are provided, for instance in the form of a rod or a rotatably bearing-mounted shaft, along which the insect screen is guided closely against the frame to prevent, in the lowered condition, a large gap between the rolling stick 3 and the lintel of the frame.
  • the rod or shaft 8 can be mounted on the supports 5, 5', but can also be mounted directly on the frame 1.
  • Figs. 2a-c identical parts are designated by the same reference numerals as in Fig. 1, with the strips of insect screen being alternately designated by 4 and 4'.
  • two rotatably bearing-mounted, elongated shafts or rolling sticks 3 and 11 respectively are provided, while the strips 4 can be wound on the rolling stick 11 and the strips 4' can be wound on the rolling stick 3.
  • two guide rods or shafts 8 and 12 Fig. 2b.
  • An advantage of the use of two rolling sticks is that the strips of insect screen 4 and 4' respectively can be wound up evenly, without overlap, which promotes a failure-free functioning.
  • the rolling sticks 3 and 11 on the one hand and the guide shafts 8 and 12 on the other can be mounted on the side supports 5 and 5' in any position relative to each other, such as above each other, next to each other, etc.
  • the guide shafts 8 and 12 need not be round, but may also be oval or the like.
  • gears 13 and 14 are provided, mounted at the end of the rolling sticks 3 and 11 respectively and meshing with each other for realizing a 1:1 transmission.
  • gears there may also be provided a rope, chain or similar coupling, or the pull 6 may drive both rolling sticks directly.
  • Fig. 2c shows a variant in which a cover 15, having for instance a substantially U-shaped section, is provided over the entire roll-up system.
  • a function of this cover may be to conceal the roll-up system and to prevent the rolled-up strips from fouling.
  • the lower edge 15' of the cover may take over the function of one of the guide shafts 8 or 12 and guide the strips tightly along the frame.
  • these strips have their lower sides for instance provided with a hem in which weighting elements 9 are arranged, or weighting elements may be fitted on the lower edge of the strips otherwise, such as by a snap connection, gluing or the like.
  • the insect curtain as a lamellar curtain, as is known for covering window sections.
  • Such curtain comprises vertical strips of textile or plastic that, by means of a construction provided at the top side thereof, can be tilted about their vertical axes and moved in horizontal direction by pull cords or rods. If in such lamellar curtain, the lamellae are designed as strips of insect screen, and the curtain is mounted in the door opening, the lamellae can, when not used, be slid aside into a position close to the door post, so that at any rate the passage is partially cleared and the incidence of light is obstructed less.
