Definitions

  • the present invention relates to a lamella for sun protection systems with lamellae hangers, which has at least one lateral receptacle for insertion of a guide nipple.
  • the object of the invention is to provide a blade which is produced inexpensively by roll forming can be and is suitable for the attachment of lateral guide nipple.
  • the object of the invention is achieved in that in a lamella of the type mentioned, the at least one receptacle is closed at the lamellar edge, each with a web which has a predetermined breaking point, which is breakable by the insertion of the guide nipple.
  • the punching image of the lamella can be performed as a closed contour, so that the cost-effective Rollformtechnik for large quantities can be used.
  • the punched image for the recordings at the fin end is designed to be closed, wherein the web is designed so that it breaks easily when inserting the guide nipple and releases the receptacle for the guide nipple.
  • the lamella is formed on both sides with corresponding receptacles for guide nipple.
  • the lamellae of the type described above may be made of plastic, but preferably they are made of metal and are produced by the rollforming method mentioned.
  • An embodiment in which the receptacles have free spaces laterally behind the webs is particularly preferred which the web parts are received when pressing the guide nipple. In this way prevents the web parts deform uncontrollably and prevent proper assembly process of the guide nipple.
  • This is particularly useful with materials for the slats, which allow after breakage or rupture of the predetermined breaking point or other breaking point a plastic deformation of the web parts, as is the case for example with aluminum sheet. But even with brittle materials in which the web parts are broken away from the lamella, the free spaces can serve to accommodate the web parts, so that they do not fly uncontrollably through the area when mounting the guide nipple.
  • a slat is formed with laterally inserted into the receptacle guide nipples that they are anchored against withdrawal from the slat.
  • This can be achieved by simply jamming the guide nipple, but also by additional measures such.
  • B. terminals can be achieved by means of additional elements, gluing, welding or positive fastening techniques.
  • a particularly simple recording can provide that the web parts are wedged after insertion of the guide nipple with this. As a result, no further measures are necessary to secure the guide nipple against undressing.
  • the guide nipples each have two planar elements which are larger than the receptacles, wherein the planar elements are connected by a rib which is adapted to the shape of the receptacle.
  • a guide nipple passes with the rib in the receptacle, wherein the rib defines the position of the guide nipple together with the two flat elements, one of which on the top and the other lies on the bottom of the slat.
  • the rib itself can be sharpened or rounded at its tip to break open as a defined abutting edge of the web at its defined breaking point.
  • pins can be fixed on at least one planar element, which project up to at least lateral extensions of the respective receptacle.
  • the pins are pushed after insertion of the guide nipple into the receptacle in the region of the extensions, wherein they are pressed captive in at least one planar element.
  • the pins can protrude into the opposite planar element and sit there in a further press fit, wherein on the opposite sheet-like element and a seat in an opening with clearance fit is possible.
  • the guide nipples are usually made of plastic, but in principle can also consist of any other material that is suitable for the present application.
  • a roll-formed lamella 10 is shown made of aluminum sheet, which is provided in the region of its lateral front end with a closed die, which has a receptacle 14 for a guide nipple 16 (see Fig. 2 ), which can be inserted into this receptacle 14.
  • the stamped image 12 is designed to be closed, ie the receptacle 14 is closed in alignment with an end edge 18 of the lamella with a web 20.
  • This web 20 has a central predetermined breaking point 22 which is formed by a taper of the web width. The connection of the web 20 to the blade 10 via lateral predetermined bending points 24, which are also formed by tapering the web width.
  • the recording Immediately behind the web 20, the recording has lateral free spaces 26, whose function will be discussed later in more detail.
  • the receptacle 14 consists of a slot with a rounded end and two lateral extensions 28, whose function will be discussed later in more detail.
  • the guide nipple 16 consists of a guide element 30, which is intended in the example shown for engagement in a guide rail, and a holding element that is intended for anchoring to the lamella 10.
  • the holding member 32 consists of a first sheet-like element 34 (see Fig. 3 ) a second planar Element 36 and a lying between these two sheet-like elements 34, 36 rib 38, the outer contour of the contour of the receptacle 14 is adjusted.
  • the distance between the two sheet-like elements 34, 36 is according to Fig. 3 chosen so that the blade 10 can be inserted without play or with little play between the two flat elements 34, 36.
  • Recognizable off Fig. 3 is the concave configuration of the facing surfaces of the two sheet-like elements 34, 36 to allow easy insertion of slats with different radii of curvature.
  • two pins 40 are fixed to the first planar element 34, preferably by a film connection in the production of the guide nipple in an injection mold.
  • the position of the pins 40 is selected so that they are aligned with the lateral extensions 28 of the receptacle 14 after insertion of the guide means 16.
  • the pins 40 may then break open the film binding from the in Fig. 3 shown position are pushed by impressions in the lateral extensions, where they finally get into holes in the second planar member 36.
  • the pins 40 are fixed permanently after pressing without further measures and secure the guide nipple 16 on the lamella body 10 against extension.
  • the type of determination of the guide nipple 16 on the lamella body 10 is of secondary importance, in principle, other measures could be taken for attachment, such as riveting, gluing or the like.
  • the blade 10 is generally provided on both sides with receptacles 14 for the guide nipple, but there are also embodiments with only one shot possible, in which case for curtains with low stress, the slats z. B. can be alternately guided laterally.
