Definitions

  • the invention relates to a slatted blind with vertical slats, with a base plate in each case at a lower end of a slat, with flexible connecting elements between the base plates of two adjacent slats and each with a holding element arranged on a narrow side of the base plate for fastening the connecting element to the base plate.
  • the base plate has the task of stabilizing the slats in their vertical position due to their weight, especially when the slatted blind is not in motion.
  • the connecting elements which are mostly chains or cords, have the task of guiding the slats, particularly in their lower region, during an adjustment of the slat blind.
  • the base plate is made of steel at the lower slat end. In some cases, these are additionally bordered on the two vertical narrow sides with rail-shaped holders made of plastic. The holding elements with which the cords or chains are attached to the holders of the base plate are separate components.
  • brackets enclosing the base plate increase the manufacturing and assembly costs.
  • the design of these brackets is also relatively complex per se, since the holding elements used for connection to the chains or cords should usually be releasably connected to the brackets or the base plate.
  • a next disadvantage is that the design described is very noticeable due to the necessary number of individual components and adversely affects the appearance of the slatted blind. Dusting and rusting of these parts is also promoted by the design described.
  • the entire base plate is made of plastic, which has a specific weight of at least 1.2 g / cm 3 , and that the base plate is designed for direct attachment of the holding elements.
  • the invention has recognized that the base plate can perform its function satisfactorily if it is not made of steel as before, but entirely of plastic, and the plastic has at least the proposed specific weight. Furthermore, the base plate made of plastic can be designed in such a way that the holding elements can be attached directly to it and additional holders, mounts or the like for the base plate are not he are required. There is thus a lower need for components, so that the manufacturing and assembly costs are reduced accordingly.
  • the base plate which is now free of mounts, mounts or the like, as a unitary component, on the sides of which there is only a small holding element in each case, ensures a much better appearance. Due to the smoother structure, the risk of disturbing dust is correspondingly lower.
  • the bottom plate functions even better if the weight of the plastic is at least 1.5 g / cm 3 , preferably at least 2 g / cm. This means that the base plate can also be used for slats made of heavier, less flexible material such as a heavy textile fabric, especially cotton.
  • the necessary total weight of the base plate is also determined by the size of the same. It is assumed within the scope of the invention that when the base plate is made of plastic, it must at least not be significantly enlarged in terms of its dimensions compared to the dimensions of the previously known base plates. A further improvement in the function of a base plate is conceivable according to the invention if the synthetic material has a homogeneous embedding made of another material, the specific weight of which is significantly greater than that of the plastic.
  • a suitable material for this is e.g. Talc, calcium or the like, which can be mixed in powder form homogeneously with the plastic.
  • the base plate has a recess open to a narrow side and that part of the holding element is designed as a plug-in part that can be inserted into the recess This results in a relatively inconspicuous and simple attachment option for the holding element. Due to the design of the base plate made of plastic, the production of such a recess is particularly simple. For the mentioned possibility of executing such a fastening, which is described in more detail below, protection should also be claimed independently of the features contained in claim 1 of this application.
  • the fastening can be designed as a latching connection, in which, according to the invention, the plug-in part is provided with at least one projection which engages in a recess formed in the recess when it is inserted into the recess.
  • the inherent elasticity of the plastic will be sufficient to ensure reliable locking.
  • the protrusion protrudes from the plug-in part in each case in the direction of one of the sides of the base plate parallel to the plane of the plate and that the recess cooperating with the protrusion is an opening in the wall delimiting the recess.
  • the opening in this case enables a latched projection to be pushed back by hand or with an aid, so that the plug-in part can be removed more easily from the recess.
  • a further advantageous embodiment of the invention is provided if the plug-in part is provided with a projection on each of two opposite sides and if the projections are offset with respect to one another with respect to the longitudinal axis of the plug-in part.
  • the depressions or openings are then also arranged in a correspondingly offset manner, so that both projections can snap into place. If appropriate, it is of course also conceivable to arrange further projections and depressions or openings. Due to the offset of the projections on the plug-in part, corresponding material accumulations are initially avoided. This also allows a specific insertion position for the plug-in part to be specified, because it will be difficult to push it into the recess in a position rotated by 180 °.
  • a next practical embodiment of the invention is that the wall delimiting the recess springs back on one side and forms a cutout which is open to the edge of the base plate, and that a cam provided on the plug-in part of the holding element engages in the cutout when the plug-in part is inserted.
  • the engagement of the cam in the cutout ensures good guidance of the plug-in part and, at the same time, creates some freedom of movement in a direction radial to the axis of the plug-in part, which reduces the friction when inserting and removing the plug-in part occupied.
  • the part of the holding element used for fastening the flexible connecting element is offset relative to the plug-in part in the direction of the upper edge of the base plate and extends at least approximately to the height thereof, and that the transition area between the plug-in part and the Attachment of the flexible connecting element-serving part of the holding element on the top have a beveled or rounded course, during which the cam on the plug-in part when inserting the same receiving cutout is expanded accordingly.
  • This in particular also facilitates the insertion of the plug-in part into the recess on the base plate.
  • a next advantageous embodiment of the invention is that the part of the holding element used to fasten the flexible connecting element has at least one receiving space, the wall of which is divided by slots into resilient wall parts, that the input cross section of the receiving space is somewhat smaller than the rest of the cross section of the same two receiving spaces are arranged side by side and that the slots in the wall lie on an axis running diametrically through the receiving spaces.
  • Such a design of the holding element is particularly advantageous if as a flexible connecting element of adjacent floor panels between the slats is used a örperettin of balls or other K interconnected existing chain.
  • the wall parts springing apart slightly. After springing back, the input cross-section is narrower than the cross-section of the ball or the body element, so that it is no longer possible to leave the receiving space without further application of force.
  • the distance between the receiving spaces is adapted to the distance between two balls or body elements on a cord or wire connecting them, the cord or wire being able to run straight through the slots in the wall.
  • This part of the holding element is expediently arranged such that the input cross section of the receiving space points in a vertical direction.
  • the base plate designated overall by reference number 10, has two vertical narrow sides 11, of which only one can be seen in FIG. 1.
  • the narrow side 11 projects somewhat outwards in the upper region and has a recess 12 in this projecting part, which opens towards this narrow side 11.
  • the cutout 12 is provided with a cutout 13, while the input cross section of the cutout 12 has an obliquely upward and outward extension 14. The function of section 13 and extension 14 will be explained in detail later.
  • the cutout 12 has an opening 15 opening toward the front side of the base plate 10 in FIG. 1.
  • the wall of the base plate 10 delimiting the cutout 12 is provided with a further opening 16, which is relative to the opening 15 with respect to the axial extent of the recess 12 is offset.
  • the holding element shown in FIGS. 3 and 4 is designated overall by the reference number 18 and is subdivided into a plug-in part 19 and a further part 20 which projects out of the base plate 10 when the holding element 18 is connected to the base plate 10.
  • the plug-in part 19 has an at least approximately rectangular, flat cross section and on two opposite sides each have a projection 21 or 22 in such a position that when the holding element 18 is inserted, the projection 21 engages in the opening 15 and the projection 22 in the opening 16 can. Furthermore, the plug-in part 19 has on the side on which the projection 21 is located a cam 23 which is adapted in shape to the cutout 13 and which is at least approximately flush with the outside of the base plate 10. Between the plug-in part 19 and the part 20 which is offset upwards a little from it, a bevelled or rounded transition surface 24 is formed, the shape of the extension 14 being adapted to the recess 12.
  • part 20 there are two receiving spaces 25 which extend in the vertical direction and are circular in cross section, the walls of which are each provided with a slot 26 at two diametrically opposite points.
  • the input cross section of the receiving spaces 25 is smaller than the cross section in the rest of the same.
  • a ball of a ball chain 27 can be pressed into a receiving space 25, the wall parts separated by the slots 26 springing slightly outwards and then springing back so that the ball chain 27 is held in place.
  • a cord connecting the balls of the ball chain 27 or a corresponding wire runs through the slots 26 lying in the same orientation and prevents the receiving spaces 25 from leaving in the direction opposite the slots 26.
  • a holding element designated overall by reference numeral 28, has a plug-in part 29 and a further part 30, the function of which corresponds to that of part 20.
  • the part 30 with the plug-in part 29 is approximately at the same height.
  • the plug part 29 is bent back like a hook at its free end, so that a projection 31 is formed there. The latter can engage in the opening 15 when the plug-in part 29 is inserted into the recess 12 in the base plate 10.
  • a cam 32 which corresponds in function to the cam 23 of the previously described exemplary embodiment, enters the cutout 13 of the recess 12.
  • the plug-in part 19 and the projection 31 of the plug-in part 29 are respectively accessible from the outside through the openings 15 and 16, the plug-in part 19 or 29 can be removed from the plug by a pressure exerted on these projections from the outside Recess 12 are facilitated.
