Definitions

  • the invention relates to an operating lever unit for windows, in particular turn-tilt windows, which has a lever element, a rosette with through openings for screws, a square pin and at least one screw cover.
  • Such control lever units form part of a fitting that is brought onto the market by all leading manufacturers a million times over.
  • the European market potential is estimated at around 25 million a year.
  • These high quantities suggest that production be rationalized as much as possible.
  • One problem relates to the manufacture of the lever element and the second problem relates to the automatic assembly of the operating lever unit consisting of the lever element, rosette, square pin and possibly other components such as a locking bush.
  • the third problem is the danger that the screw cover can be scratched.
  • Other problems arose in the market and when used in construction.
  • the commercially available control lever units have a coil spring, which has the function of pressing on the sheet metal serving as a screw cover and holding it in the cover position.
  • the need for such a spring creates a lot of disadvantages.
  • the spring requires a special handle with a recess for the spring. It is therefore not possible to use any handles as lever elements. This is particularly disadvantageous because there has been a long demand for fitting programs in which the door handle and window handle are identical.
  • the special design of the lever element serving as a handle proves to be disadvantageous in terms of design, because each lever element has to be dimensioned in such a way that there is sufficient space for the recess.
  • the feeding of coil springs proves to be very complex and limits the speed of assembly.
  • cover plates are also problematic. These can be scratched during the automatic manufacture, transport or assembly of the fitting. The subsequent replacement of a scratched cover plate proves to be impossible. It is also not possible to add customer embossing to cover plates. Rather, the dealer must order the finished operating lever unit with the label requested by the customer.
  • lever element and the rosette should be able to be designed more freely than before. It should also be possible to retrofit a rosette with the lettering requested by the customer. For the production, it is desirable that the components, such as lever element, rosette, square pin, etc., can be combined to form an operating lever unit by an automatic assembly process. Shaping of the lever element should also be avoided, which can cause difficulties in the production of the lever element in the aluminum mold casting process.
  • an operating lever unit of the type mentioned at the outset for achieving the object is characterized in that the rosette has a recess in the area of each through opening for a screw and in that the screw cover has a contour which fits into the Recess fits.
  • the control lever unit according to the invention also has the advantage that both the manufacture of the lever element and the assembly of the control lever unit are made considerably easier and cheaper. Since the screw covers can be used in the window after the fitting has been installed, there is no risk of them being scratched during manufacture, transport and installation of the operating lever unit. For customers who want so-called customer stamping, the dealer no longer has to order the finished operating lever unit with the desired label. Rather, it is sufficient to procure the screw cover provided with the inscription. In urgent cases, the operating lever unit can be delivered to the customer in advance from the warehouse, who can then install it in the window immediately. In the meantime, the screw covers can be labeled so that they are ready for insertion after the control lever unit has been installed.
  • control lever unit according to the invention now offers such window manufacturers the possibility of making cheap wholesale purchases for all branches, but ordering screw covers for each branch with the name and telephone number of the branch.
  • the respective recess of the rosette expediently has an undercut in which the screw cover can snap into place. This securely fixes the screw cover without the need for any additional means.
  • the recess and the screw cover advantageously have a square contour. This will make it easier to insert the screw cover. However, it is also possible to provide a circular contour for the same purpose.
  • a further recess for receiving a reinforcing washer can be provided under the recess for the screw cover.
  • This reinforcing disc is advantageously made of metal, e.g. galvanized iron sheet.
  • a preferred embodiment of the operating lever unit provides that the screw cover has at least one finger with a barb and that the rosette has an opening for each finger into which it can penetrate and engage with a barb. This ensures that the screw cover is securely attached.
  • the screw cover advantageously has a spring element which allows the screw cover to be displaced in order to loosen the barb and to remove the screw cover. This allows maintenance work, whereupon the screw cover can be used again without any problems.
  • a notch can be provided on the edge of the recess. This allows the screw cover to be moved using a pointed object.
  • the rosette is advantageously made of plastic. This enables a pleasing shape.
  • the screw cover is also advantageously made of plastic.
  • a commercially available operating lever unit shown in Figures 1 to 4 consists essentially of the lever element 11 made of die-cast aluminum, the pressure spring 13, the cover plate 15, the rosette 16, the locking bush 17 and the square pin 19.
  • the pressure spring 13 has the task that To hold cover plate 15 in the cover position shown in Figure 4. After driving in the screws 21, the cover plate 15 can be brought from the position shown in FIG. 3 to the position in FIG. 4 in which it covers the screws. So that the lever element 11, ie the so-called window handle, can accommodate the helical spring 13, it has a recess 14 on the handle neck. As already mentioned before, this recess 14 is difficult to manufacture in the manufacture of the lever element 11 in the aluminum mold casting process.
  • FIGS. 5 to 8 An exemplary embodiment of the operating lever unit according to the invention is shown in FIGS. 5 to 8 in analogy to the known operating lever unit shown previously.
  • This exemplary embodiment again comprises a lever element 11, a rosette 16, a locking bush 17 and a square pin 19. It is now essential that no coil spring 13 (FIG. 1) has to be provided. As a result, no recess for a helical spring is necessary in the lever element 11. As indicated, this enables the designer to make the handle neck slimmer. Even more important, however, is the more favorable shaping achieved by the elimination of the recess 14 in FIG. 1 for the production of the lever element in the aluminum mold casting process.
  • the operating lever unit shown in Figures 5 and 6 is particularly suitable for automatic assembly, since the Problems with the coil spring 13 and the cover plate 15 of Figure 1 are eliminated.
  • FIG. 7 shows the operating lever unit after being tightened by means of screws 21 on the window 22.
  • FIG. 8 shows the operating lever unit from FIG. 7 after the screw covers 15 have been inserted.
  • the design of the rosette 16 and the screw covers 15 is shown in detail in FIGS. 9 to 14.
  • the rosette 16 is made of plastic in the usual way and has two through openings 25 for screws 21 (FIG. 7).
  • the reference number 27 denotes the opening for receiving the pin 28 (FIG. 5) of the lever element 11.
  • This screw cover 15 has a contour which fits into the recess 29.
  • an undercut 31 is provided, into which the screw cover 15 can snap into place.
  • the cutouts 29 and the screw cover 15 have a square contour. This will make it easier to insert the screw cover.
  • a further recess 33 is provided under the recess 29, into which a reinforcing disk 35, e.g. made of galvanized iron sheet, can be used.
  • the rosette 16 differs from that of FIGS. 9 to 11 essentially only in that two openings 37 are provided for the fingers 39 of the screw cover 15.
  • the fingers 39 have barbs 41 which can snap into the rosette 16 in order to firmly connect the screw cover 15 to it.
  • the screw cover 15 has a slot 43, so that a web 45 is formed, which acts as a spring when the screw cover 15 is moved in the direction of the arrow 47 (FIG. 17).
  • a screwdriver can be inserted into the notch 49 of the rosette. When shifting against the force of the spring 45, the barbs 37 are released from the rosette 16 so that the screw cover 15 can be removed.
  • the screw cover 15 can be provided with a so-called customer embossing, that is to say an inscription 51.
