Definitions

  • the present invention relates to a fitting for receiving a fastened to a door handle handle, in particular a door handle, a short or long shield, or a lock cylinder, with a plane, facing the door leaf inside, which extends around an actuating axis of the handle, and at least one Attachment in which a fastener is added, which serves to fix the inside of the door leaf.
  • Door handle fittings are fastened to the door leaf with screws, with the screws screwed directly into the door leaf. Another possibility is to guide the fastening screws through the door and to secure from the opposite side to the counter fitting.
  • Door fittings are subject to different forces during daily use.
  • a handle such as door handle, doorknob or key rosette act a torque to operate the lock mechanism on the fitting.
  • a downward force on the fitting can be exercised. These forces generally act radially with respect to the actuation axis of the lock mechanism and lie in the plane of the door leaf.
  • the door can then be opened via the handle, with an axial force acting on the pusher perpendicular to the door leaf and parallel to the guide bearing for the door handle.
  • These axial forces are via a fitting-side mounting bearing taken on the door rosette or the door plate and can ultimately be derived from the fitting to the door leaf.
  • support sleeves which are mounted on the fitting and can positively engage in recesses of the door leaf.
  • support sleeves are not possible, as for example in Scandinavia, as the door side has a very large opening, which excludes the inclusion of support sleeves.
  • the fittings, in particular round escutcheons are then only on their outer annular area on the door leaf.
  • Planar fittings are in this case only positively connected to the door leaf, the adhesion is essentially determined by the tightening torque of the mounting screws.
  • the invention includes the technical teaching that the inside of the fitting, which bears against the door leaf when fastened, is provided with a structure which can bring about a positive connection between the inside and the door leaf. Due to the normal forces that arise due to the structure of the invention between the inside of the fitting and the door leaf, the radial forces acting on the fitting when pressing the lock mechanism, at least partially offset.
  • the structure may also increase frictional engagement between the inside and the door panel.
  • the structure allows that even after very frequent operation of the handle, the inside of the fitting immovably remains in its position. Furthermore, the structure prevents the fixing of the fitting on the door leaf from deteriorating over time and the fitting becoming detached.
  • the structure has at least one fixing dome, in particular two fixing mandrels.
  • the invention thus provides, in addition to the fastening means for the axial attachment of the fitting on the door leaf additional means to prevent loosening of the fitting.
  • additionally raised, point-shaped fixing mandrels are mounted on the level inside of the fitting.
  • a plurality of fixing pins can be arranged at arbitrary locations on the inside.
  • the structure according to the invention can be described mathematically.
  • the structure can thus have different geometric bodies as raised elements that can be defined mathematically.
  • the structure may be formed as any prism, pyramid or cone. It is also conceivable that several fixing mandrels uniformly over the inside can be distributed, which create a rough surface on the inside. Furthermore, it is possible to arrange a plurality of fixing mandrels only in the vicinity of the attachment points in order to increase the positive connection between the fitting and the door leaf in the vicinity of the attachment points.
  • an optimal geometric shape of the structure, the number of raised elements and their positioning for a particular fitting can be determined in order to optimize the positive connection between the inside and the door leaf.
  • the material properties of the structure or of the fitting and the door can also be included in order to adapt a choice of material of the structure of the material of the door leaf and thus to determine the appropriate material pairing.
  • the structure and the inner side form a common monolithic component. It is also conceivable that the structure is mounted on the inside of the fitting. Furthermore, it can be provided that the structure, in particular the fixing mandrels are suitably adapted to the intended use or the material of the door leaf by suitable choice of material or surface refinement.
  • the inside with the structure may be a 2-component injection molded part. Furthermore, it is possible that the structure has a greater material hardness than the inside of the fitting.
  • the fixing mandrel may have a contour which is pointed towards the door leaf.
  • the fixing mandrel can be shaped in particular as a cone or pyramid.
  • the fixing mandrel can "dig in” with the pointed free end in the door leaf. This allows the fixing mandrel now derive the radial forces acting in the plane of the inside of the handle, by positive engagement of the fitting to the door leaf.
  • the connecting path between the tip of the fixing dome and the center of the Base surface of the Fixierdoms, which lies in the plane of the inside is substantially perpendicular to the inside. It can thereby be achieved that the fixing mandrel penetrates at a right angle into the door leaf in order to allow optimum power transmission when tightening the fastening means.
  • the fixing mandrel may have a contour which is cut in the shape of a blade towards the door leaf, wherein in particular the fixing mandrel may be wedge-shaped.
  • the fixing mandrel may be embodied as a straight prism having a rectangular quadrangle as a base surface lying in the plane of the inner side and two isosceles triangles as side surfaces.
  • the fixing mandrel can be arranged on the inside, that the longitudinal side of the base surface is perpendicular to the force resulting from the radial forces acting in the plane of the inside of the fitting.
  • the force resultant of the radial forces is along the radius of the door rosette.
  • the longitudinal side of the base of the Fixierdoms be arranged perpendicular to the radius of the inside in this point.
  • a further advantageous embodiment of the invention provides that the fixing mandrel and the attachment point can lie on a line which intersects the actuating axis of the handle at a right angle.
  • the fixing mandrel can be arranged close to the fastening point.
  • two actuation elements and two fixing mandrels can be provided which lie on a line which intersects the actuation axis of the handle, in particular at a right angle.
  • an attachment point and a fixing mandrel can be arranged symmetrically with respect to the actuation axis on two opposite sides of the inner side.
  • such an arrangement provides a reinforced axial attachment of the fitting.
  • this arrangement also prevents unwanted pivoting of the fitting on the door leaf when a radial force is exerted on the fitting, such as when pressing the door handle or when turning a key in a Moscowite to act on the lock mechanism.
  • the structure may be implemented as a rough surface structure.
  • the structure may be uniformly distributed on the inside.
  • the surface structure can have a plurality of punctiform and / or linearly raised elements.
  • the surface structure may be provided only in the region of the fastening means on the inside, in order to counteract the radial forces targeted in the vicinity of the fastening means.
  • the surface structure may additionally cause a frictional engagement between the inside of the fitting and the door leaf. It is also conceivable to use not only a mathematically describable, but also a stochastic surface structure, in particular depending on the material of the fitting and on the manufacturing process of the fitting.
  • the structure may have fixation mandrels and a surface structure at the same time in order to effect a frictional connection between the inside of the fitting and the door leaf in addition to the form fit. It can also be provided that the structure is determined only by the friction-increasing surface structure.
  • a preferred embodiment of the present invention provides an inner surface which may extend annularly about the actuation axis.
  • a cover surface may be provided within the inside, which serves as a covering means for the lock mechanism.

  • the screws can in this case on the surface of the door leaf, d. H. be fixed directly on the door leaf.
  • the screws can engage in the fitting on the opposite side of the door leaf, wherein when tightening the screws both fittings are braced against each other.
  • the attachment point may have a threaded bore which is complementary to the thread of the screw.
  • FIG. 1 and below FIG. 4 show a fitting 1 according to the invention with a structure 4, which causes a positive connection between an inner side 3 and a Törberber Structure to prevent release of the attachment or slipping of the fitting 1.
  • the structure 4 comprises two fixing mandrels 5a, each of which has a pointed contour which is shaped as a pyramid.
  • the pointed contour of the Fixierdorne 5a is designed to penetrate when attaching the fitting 1 on the door leaf with its pointed end in the surface of the door panel.
  • a positive connection between the fixing pins 5a and the door leaf is provided in order to derive the radial forces exerted on the fitting 1 reliably from the fitting 1 to the door leaf.
  • the two fixing pins 5a lie on a notional line R1, which runs along a diameter of the inner side 3.
  • the fixing pins 5a are in this case arranged symmetrically about an actuating axis 9.
  • the actuating axis 9 determines the extension direction of the guide bearing for a door handle and is aligned perpendicular to the plane of the door leaf.
  • This arrangement of the fixing pins 5a prevents the inner side 3 from moving along the door leaf when forces acting in the plane of the inner side 3 act on it.
