  • door handle and olive - one set of substructure and cover rosette for the first handle - e.g. door handle - and one set of substructure and cover rosette for the second handle - e.g. olive or coin slot element - can be provided on at least one of the broad sides; a common larger cover rosette can also be provided for covering a first substructure for the first handle and for covering a second substructure for the second handle, with a corresponding first and a second cover rosette through-opening.
  • step b) comprises b1) Providing the substructure with the substructure body and an insertion sleeve, wherein the substructure body has the substructure outer contour and a substructure body through-opening whose diameter is smaller than the diameter of the cover rosette through-opening, and wherein the insertion sleeve is designed for precise insertion into the substructure through-opening and has an insertion sleeve through-opening for precise pivotal mounting of the bearing section of the handle and a cover ring for supporting a front end of the handle and for covering the inner edge region of the cover rosette.
  • steps g) and h) the substructure body is inserted, positioned and fixed in the substructure receiving recess.
  • the method further comprises the step following step j): k) Insert the insert sleeve into the substructure body through-hole.
  • step b1) comprises providing the substructure body in such a way that the side to be covered by the cover rosette is flat.
  • step k) is carried out at the manufacturing site; the door leaf is then delivered to the installation site with the insert sleeve already inserted, where the handle is then preferably mounted.
  • step k) can also be performed later, e.g., during the preparation process up to the installation site.
  • step k) is performed together with the assembly of the handle.
  • the insert sleeve can be inserted simply by axially pushing it in. However, it is also possible to screw the insert sleeve into the substructure body. For this purpose, some designs provide an internal thread for the substructure body through-hole and a matching external thread for the insert sleeve.
  • Positioning in step i) can be performed in different ways.
  • the position of the lock follower's rotational axis is detected (measured) using any known detection method, and the position is adjusted accordingly using a substructure assembly device—e.g., an assembly robot or multi-axis handling device. This can be done when inserting the substructure, in particular the substructure body, into the recess or later, before or after covering with the cover rosette.
  • step i) comprises

  • a hot melt adhesive is preferably used.
  • step i) comprises
  • step i) comprises
  • Creating the outer edge of the cover rosette recess with a step wherein a first step is matched to the thickness of the cover rosette and a second step provides space for an adhesive for fastening the cover rosette, wherein step j) fastening the cover rosette by introducing adhesive in the second step.
  • the substructure is provided with the substructure body and an insert sleeve, wherein the substructure body has the substructure outer contour and a substructure body through-opening whose diameter is smaller than the diameter of the cover rosette through-opening, and wherein the insertion sleeve is designed for precise insertion into the substructure through-opening and has an insertion sleeve through-opening for precise pivotal mounting of the bearing section of the handle and a cover ring for supporting a front end of the handle and for covering the inner edge region of the cover rosette.
  • Preferred embodiments of the invention relate to an automatic assembly of such door leaves as shown in the reference [3] under the designation "Planar” or as described and shown in the reference [5].
  • the flush-mounted handle set "Planar” was further developed, as shown in [3] and [5], and the design was modified to better enable machine production and assembly.
  • receptacles for pivot bearings of door handles are machine-made, e.g. milled out, on the door leaf, as is desired for machine-milling for flush-mounted handle sets of the type known from [5], for example, in the context of series production of the doors, the tolerances of the different individual locks to be used cannot simply be accommodated. Therefore, such machine-made bores or similar holes have to be produced with a larger bore diameter than specified by the handle manufacturers. This does not allow a positive connection between the door and handle, but only a frictional connection.
  • Some embodiments of the invention provide for very precise lock milling (example: lock pocket) in the door leaf through CNC machining. Furthermore, flush rosette milling (example: cover rosette recess) and substructure milling (example: substructure receiving recess) are also provided very precisely through CNC machining. At this point, both millings have no direct and precise relationship to the lock follower, including the corresponding tolerances.
  • Planar substructure is positioned and fastened precisely to the handle nut (or, if necessary, to the lock nut for a deadbolt, for coupling with a toilet olive, for example).
  • positioning is achieved with the help of a positioning aid, which can be designed similarly to a handle with a square spindle.
  • This positioning aid is inserted precisely into the lock nut on one side and precisely accommodates the inner diameter of the substructure in the positioning area of the substructure.
  • the resulting tolerances between the milling of the substructure in the door leaf and the positioned substructure (matching the lock nut) are accommodated by fixing the substructure, e.g., using adhesive, clamping, or similar. This fixing can be carried out, for example, by an assembly robot.
  • the fixed substructure also ensures the secure mounting of the handle set in the substructure.
  • the substructure in the area of the later rosette is flat (without a race for the handle), unlike the design known from [5]. Furthermore, the inner diameter of the substructure is slightly larger than the later associated handle neck.
  • the corresponding rosette has an inner diameter slightly larger than the inner diameter of the substructure.
  • the difference between the two inner diameters is sufficiently large that all tolerances, e.g., from the lock or manufacturing, can be accommodated without the edge of the rosette's inner diameter protruding beyond the edge of the substructure's inner diameter.
  • the deviation between the two inner diameters that is present and visible at that time is covered by an insert with a ring - insert sleeve.
  • This insert has an inner diameter that matches the diameter of the corresponding handle neck, so that the handle is guided precisely after assembly.
  • the outer diameter of the insert is precisely matched to the inner diameter of the substructure body.
  • the wider crown covers the visible tolerances between the inner diameter of the rosette and the inner diameter of the substructure body and also serves as a race and guide for the handle. This also protects the rosette from damage during handle operation.
  • this assembly part can also be performed using an assembly robot, for example.
  • the insert with crown can be pressed in at the factory or included with the handle set.
  • the insert prefferably be equipped with an external thread and the substructure body with a matching internal thread, so that it can be screwed rather than plugged in.
  • the outer edge of the rosette cutout has a step.
  • the first step is adjusted to the rosette thickness.
  • the second step provides the necessary space to accommodate the adhesive used to secure the rosette.
  • Preferred embodiments of the invention relate, starting from [3] (there the doors designated Planar), [5], [6] or [7], to further developed designs and assembly techniques for flush-mounted handle sets, which particularly preferably facilitate simpler, in particular automated, production in industrial large-scale production technology without impairing the function, durability, comfort, operability and/or high-quality appearance.
  • Fig. 1 shows an embodiment of a door 10 with frame 12 and door leaf 14 and flush door fitting 16.
  • Fig. 2 shows a front view of the lock area of the door leaf 14, where the lock 18 is a mortise lock 20, as shown in Figs. 14 and 15 shown and explained in more detail in [2], is received and fixed in a lock pocket 21.
  • Fig. 3 shows a view like in Fig. 2 on a door leaf 15 of the door wing 14 without the lock 18 and without the door fitting 16, wherein the lock pocket 21 is shown with a faceplate recess 22 for receiving the lock faceplate 24 and a box recess 26 for receiving the lock box 28.
  • Fig. 4 shows a partial section along the line AB of Fig. 1 , wherein a substructure 30 and a cover rosette 32 for flush-fitting a substructure body 34 of the substructure 30 are mounted as parts of the flush-fitting door fitting 16.
  • the substructure 30 is designed for the precise pivoting of a handle 36 of the door fitting 16.
  • Fig. 5 shows the area between A and B of the door leaf 15 and the parts of the flush-mounted door fitting 16 in an exploded view.
  • the handle 36 shown here is a door handle 38 of a handle set 40 with a design that can be selected.
  • This handle is coupled to a lock follower 44 of the mortise lock 20 by means of a handle pin 42—usually a square pin.
  • a substructure receiving recess 46 for completely receiving the substructure body 34 and a cover rosette recess 48 for flush receiving the cover rosette so that it covers the substructure body 34 are introduced.
  • the substructure body 34 is hat-shaped, with a circular-cylindrical main portion 50 and a radially annularly projecting edge portion 52 at the axial end portion that comes into contact with the cover rosette.
  • the axial end surface 54, on which the cover rosette 32 rests, is flat, so that no form fit with the Cover rosette 32 is formed, and thus the radial relative position of substructure body 34 and cover rosette is not fixed, but is variable at least within certain tolerances.
  • the substructure body 34 has a substructure body through-opening 54 for inserting the bearing area 56 of the handle 36.
  • the bearing area 56 is formed, for example, at the free end of the handle neck of the door handle 38.
  • Handle sets are available from various manufacturers, with predetermined, particularly standardized, diameters of this bearing area 56 for certain markets, e.g., the EU.
  • various door handles 38 are available that have a bearing area 56 with a diameter of 16 mm on the handle neck.
  • the substructure body through-opening 54 is significantly larger than the predetermined diameter of the bearing area 56, wherein an insert sleeve 58 with a cover ring 60 is provided, which can be inserted with its outer diameter into the substructure body through-opening 54 with a precise fit.
  • An embodiment of the insert sleeve 52 is shown in the Fig. 5 , 12 and 13 shown.
  • the insertion sleeve 58 is, for example, hat-shaped, with the cover ring 60 projecting radially at one axial end region and the other axial end 60 being insertable from the outside into the substructure body through-opening 54 when the substructure body 34 is mounted and covered with the cover rosette 32. This can be done by inserting it or, if appropriate threads are provided, by screwing it in.
  • the axial end 62 facing away from the cover ring can be conical in order to facilitate insertion of the insertion sleeve 58 into the substructure body 34.
  • the substructure receiving recess 46 has an inner diameter D46 which is much larger than the outer diameter D34 of the substructure 30.
  • the advantage of the substructure 30 is that tolerances in the position of the rotational axis of the lock follower of the assembled lock 18 can be compensated by adjusting the position of the substructure 30. Typical tolerances can be found, for example, in [4].
  • the inner diameter D46 of the substructure receiving recess is at least 0.3 mm, preferably at least 0.5 mm, for example 0.5 mm to 2 mm larger than the outer diameter D34 of the substructure, so that the radial position of the substructure can be variably selected within this area.
  • this serves for the axial positioning of the substructure 32 by resting on the edge of the substructure receiving recess 46 and accordingly has an outer diameter D52 which is larger than its inner diameter D34 but by at least the above-mentioned tolerance range, preferably significantly smaller than a minimum diameter of a radially outer boundary 64 of the cover rosette recess 48 which adjoins the substructure receiving recess 46 axially.
  • the contour and depth of the cover rosette recess 48 is precisely adapted to the cover rosette 32.
  • the cover rosette recess 48 is stepped.
  • a first step 66 viewed from the wide side of the door leaf 15, has an inner contour 68 that precisely matches the outer contour of the cover rosette 32 and a depth T1 that corresponds to the rosette thickness RD.
  • the second step 70 has a smaller diameter so that an edge of the cover rosette 32 can rest thereon and a depth T2 that is adapted to the thickness of the edge region 52. When the edge region 52 rests, a gap is formed between it and the radial boundary of the second step, which provides space for receiving an adhesive (e.g., hot-melt adhesive).
  • an adhesive e.g., hot-melt adhesive
  • the cover rosette 32 has a cover rosette through-opening 72 which is larger than the Bearing area 56 and thus larger than the through opening of the insert sleeve 58 which is precisely adapted to the bearing area 56.
  • the outer diameter of the ring 60 is dimensioned to be larger than the inner diameter of the cover rosette through-opening 72 in such a way that it can cover the cover rosette through-opening over its entire circumference in any variably selectable radial position of the substructure 30.
  • the substructure receiving recess 46 extends continuously up to the box recess 26.
  • the recesses 21, 22, 26, 46, 48 are formed as milled recesses in the door leaf body 74, which is made of machined materials, such as wood-based materials, solid wood, HDF, MDF, chipboard, plywood, laminated veneer lumber, laminated wood, optionally surface-coated or veneered.
  • the recesses 21, 22, 26, 46, 48 provided in the door leaf body 74 for receiving the lock 187 and the door fitting 16 can be machined very precisely with very tight tolerances using numerically controlled machining, in particular CNC milling.
  • Locks 18, 20 available on the market from various manufacturers have relatively large manufacturing tolerances due to cost specifications, so that the position of the lock case 28 in relation to the lock face 24 and in particular the position of the rotational axis of the lock follower 44 is subject to relatively large tolerances. Due to the different tolerances of the lock 18, 20 and the recesses 21, 22, 26, 46, 48 for the lock 30 and the door fitting 16 on the door leaf body 74, mismatches of the rotational axis of the handle 36 defined by the recesses 46, 48 on the door leaf body 74 and the position of the Rotation axis of the lock nut 44, which could impair the assembly of the handle set, the longevity and the function of the combination lock-door fitting-handle set.
  • the door leaf parts set shown is provided, which comprises the door leaf 15, the mortise lock 20, the substructure 30 and the cover rosette 32 as parts.
  • the door leaf 15 has the lock-side area made of machinable material, in which the lock pocket 21 for the precise reception of the mortise lock 18 as well as a number of substructure receiving recesses 46 matched to the number of pivot bearings of the door fitting for receiving the respective substructure 30 for the pivot bearing with corresponding cover rosette recesses 48 for receiving the cover rosette 32, which covers the substructure 30, in particular the substructure body 34, are milled.
  • the cover rosette 32 is flush and fits precisely into the cover rosette recess 48 to cover the substructure body 34 of the substructure inserted into the substructure receiving recess 46 during intended use.
  • the substructure 30 through the cover rosette 32 do not engage with each other and are therefore not prevented from radial displacement.
  • the radial position of the substructure is variable during assembly in order to compensate for tolerances and to adapt to the position of the rotation axis of the lock nut 44.
  • the cover rosette through-opening 72 bordered by an inner edge region, has a diameter that is larger than the through-opening of the substructure 30 designed to support the handle, so that the position of the rotation axis
  • the handle 36 can be adjusted radially to the cover rosette. This allows the substructure to be adjusted to the position of the lock nut during installation and secured accordingly.
