Definitions

  • the invention relates to a fitting part for doors or windows for receiving an operating element with an upper and a lower part made of different materials.
  • fitting parts are attached as door shields, lock plates, window olives or the like, directly to a door or a window (for example document DE-U-7 028 712). They are used to hold an operating element, such as a door handle, a latch, a rocker arm, and possibly a locking cylinder. With regard to suitability for use in particular, it is important that such fitting parts are designed to be stable. At the same time, the surfaces should be smooth, possibly also glossy, in order to ensure easy cleaning and to enable visually appealing designs.
  • the invention has for its object to provide a fitting part of the type mentioned above, which enables a compact design with high stability and ensures a secure fit of the upper part.
  • the object is achieved by a fitting part according to claim 1.
  • the training as a composite component enables a very compact, stable construction, inevitably ensuring a tight fit of the upper part on the lower part.
  • the lower part consists of a glass fiber and / or ceramic reinforced plastic.
  • the lower part consists of glass fiber reinforced polyamide, which has good storage properties with little wear.
  • a glass fiber content of 30% is preferably provided.
  • the lower part is designed as a rib construction.
  • This design also has the advantage that when using a plastic for the production of the lower part there is a very uniform shrinking process when cooling and the lower part remains true to size and dimension.
  • a permanent connection of the upper part and the lower part results from the fact that the lower part is extrusion-coated by the upper part.
  • the upper part forms the visible sides of the fitting part.
  • the lower part has a bearing bush for the operating element. Since the lower part is made of a material of good stability, for example reinforced polyamide, it can be assumed that this design of the bearing bush enables very wear-free storage. In particular, it is provided that the bearing bush of the lower part engages in the upper part, possibly also reaching through it. Because the control panel generally comes into contact with the fitting part with an annular flange on the visible side, this results in a very wear-resistant design.
  • the lower part has a keyhole-shaped recess which is essentially lined with the material of the upper part.
  • the upper part has at least one latchable cover cap for a fastening means lying underneath.
  • Conventional fasteners such as screws, nails, bolts or the like can be used here.
  • the upper part has a snap-on cover cap for each fastening means at each end in order to fasten the fitting part at each end.
  • a bore for a fastener is provided at the ends of the fitting part, each of which is covered by a cover cap in order to enable a stable and universal fastening.
  • the bore is formed by a sleeve formed on the upper part and penetrating the lower part, since this then consists of the generally less strong material of the upper part.
  • the sleeve projects beyond the rear of the lower part, since then two fitting parts arranged on opposite sides of a door or a window can be connected by means of plug-in screws and the sleeves by engaging holes in the door or the window for perfect positioning of the hardware components.
  • a preferred embodiment provides that its width is less than 29 mm.
  • FIG. 1 shows a door plate designed as a composite component 1 with an upper part 2 and a lower part 3.
  • the lower part consists of a glass fiber reinforced polyamide and the upper part of a very smooth plastic, such as polystyrene, polypropylene, polyamide or the like.
  • a very smooth plastic such as polystyrene, polypropylene, polyamide or the like.
  • the fitting part 1 has a bearing bush 4 for receiving an operating element, such as a door handle or doorknob.
  • the bearing bush 4 is formed on the lower part 3, so that a permanent and stable mounting of an operating member is ensured.
  • the bearing bush 4 projects through the upper part 2, so that an end face 6 of the bearing bush can serve as an axial stop for the operating element, which is also formed from the stable material of the lower part 3.
  • the upper part 2 forms a coaxial circular ring 7 around the bearing bush 4, which ends flush with the end face 6. This ensures an optical veneer in the area of the transition from control element to bearing bush 4.
  • FIG. 2 shows the top view of the coaxial arrangement of the end face 6 of the bearing bush 4, formed from the material of the lower part 3, and the circular ring 7 of the upper part 2.
  • An opposing axial stop is formed by an annular flange 18 of the bearing bush 4.
  • an operating element such as a handle, provided with an expanding core with lugs engaging behind the flange, can be fixed in the axial direction.
  • the expanding core can be designed so that it closes with the rear screw-on surface of the fitting part 1.
  • a snap-on cover cap 11 made of the material of the upper part 2.
  • the cover cap 11 covers a bore 12, the wall of which is formed by a sleeve 13 molded onto the upper part 2.
  • the upper end of the fitting part 1 - on the right in FIG. 1 - is shown without a cap 11.
  • the lower part 3 is also covered from the upper part 2 to the rear 3a in the end region of the covering caps 11. This results in a very simple injection molding, since the upper part 2 directly onto the lower part 3 Can be sprayed on using a mask. In addition, there is a stable bond between the upper and lower part.
  • edges 3c of the lower part 3 can be encompassed by the material of the upper part 2.
  • grooves 3d can also be formed in the edge regions of the undersides 3a, into which the material of the upper part 2 engages, so that it practically clasps the lower part 3.
  • the cover cap 11 is designed such that it forms a flush closure to the upper part 2, as can be seen in FIG. 2, a groove 19 being provided on the edge of the upper part 2 for the cover cap 11 only for aesthetic reasons.
  • recesses 16 are provided in the end region of the cover caps, into which corresponding webs of the cover caps 11 engage.
  • Lugs 17 are arranged on the cover cap 11 (see FIG. 3), which partially enclose the end regions of the fitting part 1 in the engaged state and engage in corresponding recesses in the lower part 3. This ensures that the cover caps 11 engage securely on the fitting part 1.
  • the fitting part 1 has a recess 8 for receiving a locking cylinder, such as a profile cylinder.
  • a locking cylinder such as a profile cylinder.
  • Figure 3 the lining of the wall 9 of the recess 8 through the upper part 2 can be seen. This ensures a rounded edge profile to the recess 8 at the front. Since the lower part is preferably held from the front when the upper part 2 is sprayed on, it is provided that a bolt with an annular flange covering the end face 6 of the bearing bush 4 is used for holding.
  • a bolt with an annular flange covering the end face 6 of the bearing bush 4 is used for holding.
  • the lower part in the upper part shape first serves a locating pin in the bearing bush 4, the contour of the locating pin corresponding to that of the bearing bush.
  • a corresponding bearing pin can be arranged in the recess 8, in which case it only engages lugs 8a of the lower part 3, while the remaining space between this profiled pin and the lower part 4 is filled by the material when the upper part is sprayed. Furthermore, two retaining pins can engage in the areas of the cover caps (such as 11) on the lower part (in FIG. 3a). Finally, a retaining ring, such as a band on the above-mentioned receiving pin, can press onto the end face 6 of the bearing bush 4. By both measures, the lower part 3b is pressed flat onto the underside of the upper part shape.
  • FIG. 3 shows ribs 14 which give the lower part 2 the necessary stability with the greatest possible material savings.
  • the fitting part 1 shown is characterized by an extraordinarily high stability with a minimum width of 24.5 mm.
  • a very appealing design of the fitting part is possible, which results in very smooth, easy-to-clean surfaces.
