Description

[0001] The invention relates to a door leaf comprising a door leaf with a door leaf body and an actuating mechanism that includes a lever handle set cooperating with a door fitting, wherein the door fitting is flush with a surface of the door leaf. The invention also relates to a method for mounting a lever handle set on a door leaf.

[0002] For technological background and state of the art, reference is made to the following literature: [1] DE 20 2005 016 217 U1 [2] DE 10 2007 000 908 B3 [3] Catalogue "Interior Doors" of Hörmann KG Sales Company, with the imprint "Status 07.2020 / Print 07.2020 / HF 86734 de / P.xxx www.hoermann.com", downloaded from the Internet on 21.12.2020 [4] EP 2 754 790 A1 [5] DE 10 2018 100 360 A1

[0003] Reference [1] describes a door leaf with a flush-mounted lever handle fitting, in which the door fitting includes a rosette disc for mounting the lever handle. An additional cover may be provided. To allow the lever handle to rotate freely on the rosette disc, the handle neck must have a groove that engages an inner edge of the disc. Therefore, only special door fittings with a special lever handle can be used; manufacturing the lever handle is complex, and subsequent depth adjustment is not possible.

[0004] Therefore, in the literature reference [2], it was proposed to improve a door leaf with a flush-mounted lever handle fitting by providing a continuous milled lever handle recess, through which a lock inserted into the door leaf is traversed. A substructure for supporting the door leaf rests on the lock. A standard door handle from a standard lever handle set can be pivotally mounted on the substructure. Such door handles have a lever body with a larger diameter at the handle neck and a plug end extending from the lever body with a uniformly smaller diameter. This plug end is inserted into a cylindrical through-hole in the substructure and is axially displaceable there until the lever handle set is axially fixed by screwing the two door handles to the lever shaft, which is usually square in shape, thus accommodating the door leaf between them.Gaps between the door handles and the substructure are compensated for with spacers. Different spacers are provided to accommodate varying door thicknesses.

[0005] Reference [3] shows examples of different doors with door leaves in different designs and with different door leaf thicknesses.

[0006] References [4] and [5] describe a base plate as a substructure and bearing arrangement for a door handle, as well as a rosette arrangement as part of a handle set, and a method for its installation. A handle set comprises a substructure and a cover on each of the broad sides of a door leaf. The substructure rests on a step of the door leaf and is screwed to the opposite substructure there. The cover is attached to the substructure by magnets or snap-fit ​​elements.

[0007] The invention aims to improve a door leaf with flush-mounted door hardware for lever handle operation and a mounting method for it with regard to greater design possibilities and simpler construction and assembly while maintaining a high quality impression.

[0008] To solve this problem, the invention provides a method according to claim 1 and a door leaf according to claim 2.

[0009] Advantageous embodiments are the subject of the dependent claims.

[0010] According to one aspect thereof, the invention provides a method for mounting a door fitting for interaction with a lever handle set, which has a door handle comprising a lever body with a larger diameter and a plug end extending from the lever body with a smaller diameter, on a door leaf comprising a door leaf body: Providing a substructure for the pivotal mounting of the lever handle set and a cover for covering the substructure, wherein the substructure has a cylindrical through-opening for the detachable insertion and rotatable mounting of the insertion end; providing a lock case recess for receiving a lock and at least one lever handle recess extending at least partially between at least one of the two broad sides of the door leaf and the lock case recess in the door leaf body such that the substructure and the door fitting can be received in the lever handle recess in such a way that the door fitting is flush with a surrounding surface of the door leaf and the substructure can be supported on a step formed on the door leaf body between the lock case recess and a support area of ​​the substructure.Floating mounting of the substructure in the lever handle recess and fixing of the substructure by means of the flush-mounted cover or by means of the flush-mounted cover and a hot-melt adhesive.

[0029] It is preferred that the door leaf is designed as a hinged leaf for a hinged door.

[0030] It is preferred that the door leaf body is made of wood-based materials.

[0031] It is preferred that the door leaf body is designed as a panel or as a frame for a door leaf infill. The door leaf body can be a solid panel or have a window cutout.

[0032] The following section explains some advantages of particularly preferred embodiments of the invention.

[0033] The substructure is designed in such a way that it no longer needs to be supported by the lock, but by the door material itself.

[0034] Tolerances in the lock case thickness preferably have no effect, and the lock can be replaced without problems.

[0035] The substructure acts as a depth limiter and contact surface for the actual push button, so that the previous compensating washer can be omitted.

[0036] The cover, which may be designed as a rosette, can be made of metal, but also of an HPL or plastic disc.

[0037] Possible design requests or desired contrasting surfaces to the handle or door surface can be implemented quickly and easily.

[0038] In a preferred design, the substructure rests on the outer area of ​​the handle hole milling. Therefore, manufacturing tolerances of the lock, the lock position, and the milling of the substructure can be easily accommodated.

[0039] According to the invention, a floating mounting of the substructure in the handle hole milling is provided.

[0040] According to an alternative, in conjunction with the flush-mounted cover, in particular a rosette, and a ring projecting towards the handle on the substructure, the two parts can be precisely centered and fixed over the lock follower, for example, using hot melt adhesive. According to another alternative, the cover, particularly in the form of a rosette disc, acts as a mounting or fixing element for the substructure.

[0041] For this purpose, it is preferably provided that an outer area of ​​the lever handle recess with the largest diameter, in particular an outer milling for the cover or rosette, is precisely aligned with the lock nut.

[0042] Preferably, hot melt adhesive fills the cavity under the rosette and secures not only the rosette but also the substructure at the same time.

[0043] The substructure, preferably in conjunction with the hot melt adhesive, acts as a depth limiter during the installation of the cover, in particular the rosette.

[0044] In conjunction with increased heat, the hot melt adhesive can be softened and the cover / rosette can be replaced if necessary.

[0045] In conjunction with a suitable substructure, an LED circuit board can be placed under the cover / rosette. This allows the outer edge of the cover, especially the rosette, to be illuminated. The size of the cover (especially the rosette) preferably remains unchanged, so that standard, mass-produced covers, such as existing rosettes, can be used. To create light transmission, the outer milled diameter is preferably slightly larger than that of other door leaves without illumination.

[0047] The exemplary embodiments described below relate, for example, to a Fig. 1 The door leaf 10 shown has a door leaf 18 and an actuating mechanism 12 for actuating the door leaf 10, wherein the actuating mechanism 12 has at least a lever handle set 14 and a door fitting 16 which is arranged flush with a door leaf 18 of the door leaf 10.

[0048] The door, which has door leaf 10, can be designed in different ways. For example, folding doors and sliding doors are possible. Fig. 1 Figure 1 shows a preferred embodiment of a door equipped with a door leaf 10, a hinged door 20 with a frame 22, to which the door leaf 10 is hinged by means of door hinges 24 so as to rotate about a lateral vertical axis.

[0049] In embodiments not shown, the actuating mechanism 12 may only comprise a door handle assembly 26 (without a locking mechanism). The door handle assembly 26 then includes the door fitting 16, designed as a lever handle fitting for pivoting door handles 42 of the handle set 14, the handle set 14, and a catch (not shown) actuated by the handle set 14. In the embodiments shown, the actuating mechanism 12, in addition to the door handle assembly 26, also includes a locking element assembly 28 for locking the door. For this purpose, the actuating mechanism 12 may be equipped with a conventional lock 30. The lock may be designed as a key-operated mortise lock or a profile cylinder lock.Alternatively, the lock 30 – particularly for use with the hinged door 20 as a WC door or bathroom door, or the like – can be designed as a WC lock operated with a WC handle 70, in which a square spindle is provided instead of a lever or profile cylinder opening. Such common locks 30, available on the market from various manufacturers, have, as is well known, a catch (not shown) that can be retracted against a preload by means of a square spindle rotatable by the lever handle set 14, and a bolt that can be moved between at least one locked position and a release position by means of a profile cylinder, a lever key, or the locking square spindle rotatable by a WC door locking element 72 (e.g., with WC handle 70) or the like.

[0050] The door handle arrangement 26 is used for the swing door 20. Fig. 1in the door handle area between arrows A and B, and embodiments of the door handle area with the door handle arrangement 26 or of preliminary stages for forming the same are shown in the sectional view along line AB in the Fig. 2 and 5 to 7 The locking element arrangement 28 is shown. Fig. 1 in the locking element area between arrows B and C, and embodiments of the locking element area with the locking element arrangement 28 or of preliminary stages for forming the same are shown in the sectional view along line BC in the Fig. 3 , 4 and 5 to 7 depicted. The ones in the Fig. 2 and 4 The door fittings 16 shown in 5 to 7 can be used in almost identical designs for pivot bearing door handles 42 or for pivot bearing the WC door locking element 72 of the operating mechanism 12.

[0051] The different embodiments of these door fittings 16, designed for pivot bearing, each have a substructure 32 and a cover 34 on each broad side 31a, 31b of the door leaf 10. Exemplary embodiments of the substructure 32 are shown in the Fig. 2 , 4 , 6 , 7 , 11 to 15 , 18 and 19 Examples of the covers 34 are shown in the Figs. 1 to 4 and 6 to 10 depicted. Fig. 16 and 17 show a coin slot element 74 of the WC door locking element 72, which is to be arranged on the broad side of the door leaf 10 opposite the WC handle 70.

[0052] The substructure 32 has, according to the Fig. Fig. 2 , 4 , 6 , 7 , 11 to 15 , 18 and 19A ring-shaped, in particular circular, substructure body 36 is formed, in which a cylindrical passage opening 38 is formed in the center. The substructure body 36, and thus the passage opening 38 formed therein, has an axial extent – ​​corresponding to the thickness of the substructure body 36 – of at least 2 mm in order to provide sufficient bearing surface to absorb tilting moments on the door handle 42 mounted therein. In particular, a thickness of 2 mm to 20 mm, preferably 3 mm to 10 mm, and especially preferably 4 mm to 7 mm, such as 5.5 mm, is provided for the substructure body 36.

[0053] The inner diameter D i of the passage opening 38 is precisely adapted to the outer diameter DT of a insertion end 40 of the door handle 42 of the handle set 14 to be stored, i.e. just so much larger than the outer diameter of the insertion end 40 that the insertion end 40 can be inserted without play.

[0054] An example of the lever handle set 14 is in Fig. 2 indicated. Such a lever handle set 14, as it is in Fig. 2 As shown, this can be combined with the different ones in the Fig. 2 , 6 to 7 The illustrated versions of the door fitting 16 are used, which is why they are only used once in Fig. 2 The lever handle set 14 is shown as an example. It is a standard lever handle set 14, available on the market with various handle designs. It comprises two door handles 42 and a lever shaft 44, here in the form of a square shaft. The door handle 42 has a lever body 46 with a grip area (not shown) and a grip neck 48, and a projection end 40 extending from the lever body 46, which has a uniform diameter DT that is smaller than the diameter D DK of the lever body 46. Thus, a stop surface 50 is formed at the transition between the lever body 46 and the projection end 40.

[0055] For some lever handle sets 14 on the market, the diameter DT of the insertion end 40 DT = 16 mm. Accordingly, the diameter D i of the through-hole 38 is, for example, in the range of 16.05 mm ≤ D i ≤ 16.10 mm.

[0056] In the center of the insertion end 40 and the handle neck 48, a receiving opening (not shown) complementary to the lever shaft 44 is typically formed, allowing the door handle 42 to be attached to one end of the lever shaft 44. A threaded bore with a setscrew (both not shown) is provided on the side or underside of the handle neck 48, enabling the door handle 42 to be fixed to the lever shaft 44. By fixing both door handles 42 to the lever shaft 44, which is inserted through the lock 30, with the stop surfaces 50 abutting the door fitting 16, the handle set 14 is fixed axially. When the fixing between the lever shaft 44 and one of the door handles 42 is released, the insertion end 42 can be moved axially in the through-opening 36 for assembly and disassembly.

[0057] The outer diameter D Ua of the substructure body 36 is preferably in the range of 20 mm to 45 mm, more particularly in the range of 25 mm to 40 mm, preferably in the range of 29 mm to 33 mm.

[0058] The substructure 32 is manufactured in particular as an injection-molded part made of plastic, more specifically of polyoxymethylene (POM).

[0059] The in Fig. 4 left and in the Figs. 14 and 15 The modified versions of the 32m substructure shown are specifically designed for the rotary bearing of the in Fig. 4 left and in the Fig. 16 and 17The coin slot element 74 is formed as shown. The coin slot element 74 has a head 78 provided with a coin slot 76 and a cylindrical main body 80 with the same outer diameter DT as the insertion end 40, wherein a groove 82 for a retaining ring 84 is provided at the end of the main body 80 opposite the head 78. The substructure body 36 of the substructure 32m for the coin slot element 74 has the through-opening 38 and additionally at an end region of the substructure body 36 an enlarged area 85 which has a diameter DS large enough to accommodate and receive the retaining ring 84.

[0060] The substructure 32 has a support area 52 with which it is directly supported against a door leaf body 54 of the door leaf 18. The door leaf body 54 has a lock case recess 56 in which the lock 30 is preferably precisely fitted, and a handle recess 58, which extends continuously from the respective broad side 31a, 31b to the lock case recess 56. Preferably, the handle recess 58 is designed as a through-hole or through-milling cut transversely through the door leaf body 54, which is made of materials suitable for machining, such as wood-based materials, solid wood, HDF, MDF, particleboard, plywood, laminated veneer lumber, laminated wood, optionally surface-coated or veneered. Thus, the recesses 58, 56, 58a, 66 to be provided in the door leaf body 54 for receiving the actuating mechanism 12 can be machined out of the door leaf body 54 by machining.Preferably, the lock case recess 56 is produced last.

[0061] The lever handle recess 58 shows, as can be seen from Fig. 2 and 5 to 7 It is evident that at least one step 60 is provided for supporting the support area 52 of the substructure 32. For this purpose, the push-button recess 58 has a first area 62 of smaller diameter D 1 located further inwards and a second area 63 of larger diameter D 2 located further outwards, in which at least the support area 52 of the substructure 32 is accommodated.

[0062] The cover 34 is designed as a flat disc. For example, the cover 34 is made of metal, in particular steel, more specifically stainless steel, or other metal with a high-quality surface finish, or of a material whose appearance is adapted to the surface surrounding the door leaf 18 around the actuating device 12. For example, the cover 34 is made of an HPL disc or a plastic disc. The cover 34 can have different contours. For example, the cover 34 can be designed as a door plate, which is provided with corresponding openings for the door handle 42 and the keyhole or the WC door locking element 72. Preferably, the cover 34 is designed as shown in the Figs. 1 to 4 and 6 to 10depicted as a rosette, i.e., as an annular element with a central opening, wherein, in the presence of the locking element arrangement 28, a door handle rosette and, below it, a locking element rosette for which the corresponding locking element is provided are located on each broad side 31a, 31b. Fig. 8 An example of a design of cover 34 as a door handle rosette is shown, which can also be used identically as a rosette for the WC door locking element 72. Fig. 9 An example of a design of cover 34 as a rosette for a profile cylinder is shown. Fig. 10 Figure 1 shows an embodiment of the cover 34 as a rosette for use with a lever tumbler lock. Each of these covers 34 is formed by an annular disc whose thickness is preferably in the range of 0.25 mm to 2 mm, more preferably 0.5 mm to 1 mm, and most preferably between 0.6 mm and 0.8 mm.

[0063] Even when designed as a rosette, different outer contours of the cover 34 are possible. For example, the rosette can have a square, rectangular, or otherwise polygonal outer contour. Preferably, the outer contour of the rosette is circular, preferably with an outer diameter D Ra in the range of 30 mm to 65 mm, more preferably 40 mm to 60 mm, and most preferably between 50 mm and 55 mm, e.g., 52.5 mm.

[0064] To receive the insertion end 40, the cover 34, which is to be used in conjunction with the door handle 42 or the WC door locking element 72, has a preferably circular inner opening 64. The inner opening 64 preferably has a diameter D Ri in the range of 17 mm to 30 mm, in particular 19 mm to 25 mm and most preferably between 20 mm and 22 mm, e.g. 20.5 mm.

[0065] Fig. 3 shows an embodiment of the locking area of ​​the door leaf 10 in section along line BC of Fig. 1 , which is designed for a profile cylinder lock or a lever lock. Here, the door leaf body 54 has a cylinder recess 66 extending through the door leaf 18, with a narrower area 66a having a diameter Dv that can be larger than the smallest diameter D1 of the handle recess 58. On the outside of each broad side 31a, 31b, the cylinder recess 66 has a wider cover receiving area 68, the depth and contour of which are adapted to the dimensions of the cover 34 in order to fit it precisely into the cover receiving area 68 such that the cover 34 is flush with the surface of the door leaf 18 around the cover receiving area 68. In other words, the depth of the cover receiving area 68 corresponds to the thickness of the cover 34. In the Figs. 8 to 10In the illustrated embodiment of the cover 34 as a circular rosette with outer diameter D Ra, the cover receiving area 68 is also circular with an inner diameter selected to ensure a precise fit for the rosette. For example, the inner diameter D Ai of the cover receiving area 68 is a few hundredths of a millimeter (e.g., 0.05 mm to 0.1 mm) larger than the outer diameter D Ra of the rosette.

[0066] The following section describes the special features of a first embodiment based on the representation in the Fig. 2 and 4 explained in more detail.

[0067] During a Fig. 2 In the first embodiment shown, the push-button recess 58 also has, in addition to the first area 62 with smaller diameter D 1 and the further outwardly located second area 63 with larger diameter D 2, the cover receiving area 68 at the very outer edge on the broad side 31a, 31b as shown. Fig. 3This explains why a second stage 69 is formed at the transition between the second area 63 and the cover reception area 68.

[0068] In the first embodiment, the substructure 32 is cylindrical and consists of the annular substructure body 36. An outer edge at an inwardly directed end of the substructure body 36 is used as the support area 52.

[0069] The depth and diameter D 2 of the second area 63 are dimensioned here to precisely accommodate the substructure 32. Thus, the substructure rests on a first step flank at the first step 60 for axial positioning and is positioned radially by the boundary wall of the second area 63, terminating flush with a second step flank at the second step 69.

[0070] The cover 34 rests on the second step flank at the second step 69 and on the substructure body 36 and is flush with the surface of the door leaf 18 around the cover 34.

[0071] To compensate for the depth of the door handles 42, a compensating washer 86 is provided on both broad sides 31a, 31b.

[0072] If the door leaf 10 of the first embodiment is used as a WC door or bathroom door or the like, then the locking element area in the area of ​​the bolt of the lock 30 has the following features: Fig. 4 demonstrated training, which largely corresponds to the training of the in Fig. 2 The door handle area shown corresponds to the door leaf body 54, which is provided with a WC locking element recess 58a, corresponding to the handle recess 58 described above. Fig. 2This corresponds to the steps 60, 69 and the areas 62, 63, 68. The substructure 32, 32m is formed by the annular substructure body 36, which, as described above, is modified on the left side to support the coin slot element 74. The coin slot element 74 is placed on the square shaft with a complementary opening and fastened with a screw 88 and secured to the substructure body 36 of the modified substructure 32m with the retaining ring 84. On the right is the WC handle 70 with a insertion end 40 as shown for the door handle 42. The WC handle 70 is also fixed in the same way as described above for the door handle 42. Depth adjustment is achieved here by a suitable number of shims 86 – in this case, two – between the cover 34 and the stop surface 50 of the WC handle 70.

[0073] If a profile cylinder lock or a lever lock is used in the first embodiment, the locking area has the following features: Fig. 3 The training shown is the one already described above.

[0074] The following will be based on the Figs. 5 to 7 as well as details of a second embodiment of the door leaf, as described in sections 11 to 17. Fig. 5 shows the section along AB and – when used as a WC door or bathroom door or the like – also along BC through the door leaf, whose door leaf body 54 is already provided with the handle recess 58 or the corresponding locking element recess 58, before the insertion of the lock case recess 56. Fig. 6 The figure also shows the door fitting 16, once mounted on the door leaf and once in a partially cutaway exploded view. Figs. 11 to 15 show different views of the substructure 32 according to the second embodiment, wherein the Figs. 14 and 15The variant for the rotary bearing of the coin slot element 74 is shown, which alone is once again in Fig. 16 and 17 is shown.

[0075] In the second embodiment, the substructure 32 comprises the substructure body 36, with a flange 90 projecting radially from a first end of the latter. Preferably, the flange 90 is annular in shape at an end edge region of the substructure body 36, with a flange diameter DF that is—preferably by a few millimeters—larger than the outer diameter DUa of the substructure body 36. For example, the flange diameter DF is 1 mm to 10 mm larger than the outer diameter DUa of the substructure body 36. The flange 90 has a significantly smaller axial extent (flange thickness) than the substructure body 36. The flange thickness dF is selected to be just large enough that the flange 90 can serve as a support area 52 for positioning the substructure 32 without deformation. The substructure 32 is supported on the side of the flange 90 facing the other end of the substructure body 36.

[0076] Furthermore, a contact surface 92 for the direct support of the stop surface 50 is formed on the substructure 32 of the second embodiment. For this purpose, an axial annular projection 94 is formed around the through-opening 38 at the outwardly directed end of the substructure body 36, on which the flange 90 is also arranged. The projection 94 has an outer diameter D Ka, which is dimensioned such that the projection 94 can engage precisely, i.e., without play, in the inner opening 64 of the cover 34.

[0077] In the handle recess 58 or the locking element recess 58a in the door leaf body 54 according to the second embodiment, only the innermost first area 62 with a narrower diameter D1 and the outermost second area 63 with a wider diameter D2 are provided, forming a modified shape of the cover receiving area 68 as follows. The cover receiving area 68 formed by the second area 63 is contoured to fit the cover 34 precisely. The depth of the second area 63 corresponds to the sum of the thickness of the cover 34 and the flange thickness dF. The flange 90 rests on the step 60 formed between the first and second areas 62, 63 as a support area 52. The diameter D1 of the first area 62 can be precisely matched to the outer diameter of the substructure body 36.Preferably, however, the diameter D 1 is one or more millimeters larger than the outer diameter D Ua, but also smaller than the flange diameter DF.

[0078] The flange diameter DF is significantly smaller than the diameter D2 of the second area 63, which forms the cover receiving area 68. The second area 63 is precisely aligned with the corresponding nut of the lock 30. Thus, only the stepped flank of the step 60 and the outer wall of the second area 63 serve as mating surfaces; all other areas of the handle or locking element recess 58, 58a can be formed with lower precision.

[0079] To mount the door fitting 16, the substructure 32 is inserted so that the substructure body engages in the first area 62 and the flange 90 rests on the step 60. Hot melt adhesive is then poured into the second area 63 and the cover 34 is inserted. While the hot melt adhesive is still liquid, the substructure 32 is aligned radially with the cover 34 to insert the projection 94 precisely into the inner opening 64. The height of the projection 94 is dimensioned so that it completely extends through or protrudes from the inner opening 64. The hot melt adhesive is poured in to fill any gaps in the second area 63.

[0080] The lever handle set 14 is then attached, with the stop surfaces 50 resting directly on the corresponding contact surfaces 92. Compensating washers 86 are therefore not necessary.

[0081] When used as a WC door or bathroom door, the WC door locking element 72 is attached accordingly.

[0082] If the door leaf 10 is equipped with a profile cylinder lock or a lever lock, then the locking element area of ​​the door leaf is also designed in the second embodiment as shown in Fig. 3 as shown and described above.

[0083] The following section describes the special features of a third embodiment based on the illustrations in Figs. 18 and 19This is explained in more detail below. These figures show a modified substructure 32b for receiving an LED lighting unit (not shown). The substructure body 36 of this substructure 32b is made of a transparent material (in particular plastic / POM) and has an outer diameter DUa, which is a few millimeters larger than the outer diameter DRa. At an inwardly facing end, a chamber 100 for receiving the lighting unit (e.g., a circuit board equipped with LEDs) is arranged in the substructure body 36 in an area around an annular wall boundary 98 of the through-opening 38.At the outwardly directed end of the substructure body 36, the cover receiving area 68 is formed as an annular recess around the projection 94, which is therefore formed on the substructure 32 and not in the passage recess - lever handle recess 58 or locking element recess 58a or locking cylinder recess 66 - in the door leaf body 54.

[0084] The passage opening 58, 58a, 66 has approximately the same dimensions as in Fig. 5 shown shape, but the second area 63 is for the precise fitting of the in the Figs. 18 and 19 The substructure shown is designed and dimensioned as shown in 32b.

[0085] For further possible designs of the door leaf 10, reference is made to the literature reference [3], which shows different possible further designs of the door leaf 10 and the door fitted with it.

[0086] A door leaf (10) is described, comprising a door leaf (18) with a door leaf body (54) and an operating mechanism (12) that includes a lever handle set (14) interacting with a door fitting, wherein a substructure (32) for pivoting the lever handle set (14) and a cover (34) for covering the substructure (32, 32m, 32b) are provided.

The substructure (32) has a cylindrical through-opening (38) for detachable insertion and rotatable bearing of the insertion end (40) without a retaining ring or the like.The door leaf body (54) includes a lock case recess (56) for receiving a lock (30) and at least one handle recess (58) extending at least partially through the door leaf (18) between at least one of the two broad sides (31a, 31b) and the lock case recess (56). The handle recess accommodates the substructure (32) and the door hardware (16), so that the door hardware (16) is flush with a surrounding surface of the door leaf (18). The substructure (32) is further supported on a step (60) formed on the door leaf body (54) between the lock case recess (56) and a support area (52) of the substructure (32). Reference symbol list:
