Description

[0001] The invention relates to a door hinge comprising a first hinge part and a second hinge part according to the preamble of claim 1. These are pivotably connected to one another about a vertical hinge pivot axis and have a receiving part associated with the second hinge part, wherein the second hinge part is adjustably arranged with a retaining section in a receiving space of the receiving part and extends out of the receiving space in the direction of a hinge roller section along a first horizontal direction. Furthermore, it is provided that the second hinge part is adjustable relative to the receiving space to allow adjustment during the mounting of a door leaf on the door frame, typically with at least two of the described door hinges, or even in the mounted state. A door with at least one such door hinge is further described.

[0002] Multidimensionally adjustable door hinges are known from DE 103 56 403 B3 and DE 43 07 067 A1. In the known door hinges, the first hinge part is designed for attachment to a door leaf and is therefore referred to as the leaf part or leaf flap. The second hinge part forms a frame part, with the associated receiving part being referred to as the frame receiving part or hinge pocket. A corresponding functional and conceptual classification may also be advantageous within the scope of the present invention.

[0003] The present invention relates specifically to a design as described in the aforementioned prior art. The wing part and the frame part are pivotably connected to each other about the vertical hinge axis. The assignment of the vertical direction refers to the usual arrangement of the hinge on a door, in which a door leaf is pivotably attached to a door frame by means of the hinge.

[0004] According to DE 103 56 403 B3, the frame part is adjustable relative to the frame mounting part in three directions, allowing the door leaf to be adjusted relative to the door frame vertically, along the thickness of the closed door leaf (pressure adjustment), and horizontally in the plane of the closed door leaf (lateral position). For this purpose, the frame part is connected to the mounting part at the retaining section about a pivot axis aligned parallel to the hinge axis. A pivot angle between the frame part and the frame mounting part can be adjusted by means of a screw acting along a second horizontal direction with respect to the pivot axis. By actuating the screw, the frame part can be adjusted relative to the frame mounting part to a certain extent, for example, approximately + / - 2°.With a typical arrangement of the frame mounting part in one end face of the door frame, lateral adjustment can thus be provided along the second horizontal direction. Therefore, with respect to the closed position of the door leaf, actuation of the screw mechanism acting along the second horizontal direction also causes a movement of the door leaf along the second horizontal direction.

[0005] With regard to the described arrangement, the first horizontal direction corresponds to the thickness direction of the closed door leaf. As explained previously, the frame section extends out of the frame receiver section along the first horizontal direction. Considering the above explanations, it becomes clear that the frame section does not have to run exactly along the first horizontal direction, but can be tilted slightly, for example by + / -2°, as described. At least with regard to the orientation of the frame section, the first horizontal direction is a principal direction of extension.

[0006] A lateral adjusting screw is provided as a screw element acting along the second horizontal direction. This screw extends through the frame mounting part and is fixed on the outside of the frame mounting part by a screw head on one side and a pressed-in washer on the other. The lateral adjusting screw engages a bolt that is rotatably mounted in a vertical bore of the frame part. Such an articulated arrangement is advantageous for compensating for the pivoting movement of the frame part relative to the frame mounting part.

[0007] For adjusting the frame part relative to the frame mounting part along the first horizontal direction, an eccentric arrangement is provided on the retaining section of the frame part. The eccentric arrangement comprises an adjusting eccentric located in an eccentric opening of the retaining section and attached to the frame mounting part by a screw on one side. On the opposite side, the adjusting eccentric has a tool receptacle accessible through an opening in the frame mounting part.

[0008] Finally, adjustability along the vertical direction is also provided, whereby the frame part can be raised and lowered relative to the frame mounting part using an adjusting screw via a wedge surface. It is understood that corresponding degrees of freedom with regard to movement are provided for the described three-dimensional adjustment.

[0009] The wing component, the frame component, and the frame mounting component can be formed from metal casting, particularly zinc die casting. The well-known door hinge is characterized by good functional properties and low wear, although its production involves considerable manufacturing effort.

[0010] In the generic DE 43 07 067 A1, a screw in the form of a setscrew is provided for adjustment along the second horizontal direction. This setscrew is supported on the inner side of the receiving chamber in the area of ​​a thin side wall of the tape pocket. The setscrew acts on a retaining piece to which a roller flap is fixed with a clamping element and clamping screws. The retaining piece, the roller flap, the clamping element, and the clamping screws together form a second tape part as defined in the preamble of claim 1. To ensure a captive arrangement after the retaining piece with the roller flap attached to it has been inserted into the tape pocket, a countersunk rivet is provided for fixation. To allow for tilting during adjustment with the setscrew, despite the countersunk rivet being provided as a locking device, a certain amount of play is provided.

[0011] Against this background, the present invention aims to simplify the manufacturing of a generic door hinge and to further improve its functional properties.

[0012] The subject matter of the invention and the solution to the problem are door hinges according to claim 1. Furthermore, the invention relates to a door according to claim 8.

[0013] The present invention relates to an improvement of an eccentric arrangement in which the second hinge part is adjustable relative to the receiving part along the first horizontal direction on the holding section. The two adjustment options described in detail below are particularly preferably implemented in combination in the door hinge, whereby an adjustment along a vertical direction can also be provided in a manner known per se.

[0014] According to the invention, starting from the preamble of claim 1, a pivot pin of the eccentric arrangement extending along a second horizontal direction is radially supported at both ends relative to the receiving body. In contrast to a one-sided support known from the prior art, this results in less wear, greater accuracy, and, with a suitable design, less play. Despite the minimal play, the radial support at both ends also ensures particularly smooth rotation over the long term.

[0015] To support the pivot pin radially at both ends against the receiving body, the pivot pin can be easily positioned against corresponding bores or openings. Consequently, the pivot pin can be fully inserted into the receiving body without protruding beyond any associated side walls.

[0016] According to a preferred embodiment, the eccentric arrangement comprises a preferably barrel-shaped adjusting eccentric, with the pivot pin extending through the adjusting eccentric. During assembly, the adjusting eccentric can initially be loosely arranged in an eccentric opening of the retaining section. After the second band section is inserted into the receiving section, the adjusting eccentric is accessible from at least one side of the receiving body through an opening. From this side, the pivot pin can then be pressed into a bore of the adjusting eccentric, thereby permanently and rotationally fixedly connecting the pivot pin and the adjusting eccentric in a frictional connection. A positive fit is also possible, either additionally or alternatively, through appropriate contouring.

[0017] If the pivot pin is inserted into the receiving part from one side in the manner described and connected to the adjusting eccentric, an opening or merely a recess, for example in the form of a blind hole, can optionally be provided on the other side.

[0018] According to a preferred embodiment of the invention, the pivot pin has a shaft and a head projecting radially from the shaft, preferably a cylindrical head with a tool receptacle. The pivot pin can then be pressed in until the head rests against the adjusting eccentric. The pivot pin can be formed in a particularly simple manner by a conventional screw, especially a socket head cap screw with or without threads. If a commercially available socket head cap screw with a thread is provided, the corresponding bore in the adjusting eccentric must be dimensioned such that the desired rotationally fixed connection is achieved during pressing in.

[0019] As a second aspect, a possible embodiment of the invention deals with improving the arrangement of a screw means acting along a second horizontal direction, with which a pivot angle between the second band part and the receiving part can be adjusted with respect to the pivot axis.

[0020] According to the second aspect, it is provided that the screw is arranged at at least one of its ends in a groove running along the first horizontal direction on the inside of the receiving space.

[0021] According to a further development, the screw connection is provided with a tool holder at a first end, the tool holder being accessible through an adjustment opening in the holder. If – as described below – adjustment along the first horizontal direction is also provided according to the second aspect, the adjustment opening is expediently designed as an elongated hole. It is understood that the adjustment opening is made large enough to allow access to the tool holder while simultaneously ensuring that the horizontal support of the screw connection along the second horizontal direction on the inside of the holder is not impaired.

[0022] According to the second aspect, the screw is arranged at at least one end in a groove running along the first horizontal direction on the inside of the receiving space. This groove guides the screw during hinge assembly when the second hinge part is inserted into the receiving part. Additionally, this provides particularly advantageous vertical support for the screw, preventing excessive play and / or tilting. The groove thus supports and secures the corresponding end of the screw not only along the second horizontal direction (the axial direction of the screw) but also vertically. It is especially advantageous if a groove is provided at each end of the screw.

[0023] According to a further development of this concept, the screw element has a head with a collar, wherein the groove associated with the head transitions from a first groove section into a narrower second groove section, the collar being supported by the step, and an inner head section located within the collar being exposed and unsupported in the second groove section. The axial support of the screw element along the second horizontal direction is then provided by the collar and step, which are expediently arranged parallel to each other to ensure good, uniform force distribution with low wear. The exposed inner head section, on the other hand, is easily accessible and rotatable without binding.

[0024] As already known from DE 103 56 403 B3, a particularly preferred circular cylindrical bolt is advantageously movably received in an associated cylindrical bore in the holding section, with the screw engaging in an internal thread of the bolt. As also explained in connection with the cited prior art, the bolt can then compensate for the adjustment of the pivot angle between the second band section and the receiving section with respect to the pivot axis by rotating it in the cylindrical bore.

[0025] In the described embodiment, adjustment by actuating the screw element acting along the second horizontal direction is easily accomplished with minimal play. To eliminate any remaining play and / or to permanently fix the setting, the receiving part can have at least one fixing element, particularly in the form of a threaded pin. This fixing element can then be locked against the holding section to secure the pivoting movement about the pivot axis. A fixing mechanism with two fixing elements is particularly preferred to ensure exceptionally uniform mechanical tension.

[0026] As previously explained, the described adjustment options are preferably combined in the door hinge to allow adjustment along the first horizontal direction and the second horizontal direction in a particularly advantageous manner. Additionally, it is preferably provided that the second hinge part is adjustable along the vertical direction by means of a height adjustment device.

[0027] According to a preferred embodiment of the invention, the second strip section and / or the receiving part are each formed in one piece as a metal casting. The second strip section and / or the receiving part are thus produced in a single primary forming process, allowing for the easy realization of different wall thicknesses, openings, and other contours. The primary forming process is generally readily apparent from the shape and microstructure of the second strip section and / or the receiving part. Zinc die casting is particularly preferred. The first strip section can also be formed in one piece as a metal casting in the manner described.

[0028] The invention also relates to a door with at least one hinge, which is designed as described above, wherein the first hinge part is attached to a door leaf and can therefore also be referred to as a leaf part in accordance with the prior art according to DE 103 56 403 B3. The receiving part, on the other hand, is inserted into a door frame, wherein the second hinge part can accordingly be referred to as a frame part.

[0029] The invention will be explained below with the aid of figures. These show: Fig. 1 shows an exploded view of a door hinge according to the invention, Fig. 2 shows the door hinge according to the Fig. 1 In the assembled state, Fig. 3, the door hinge according to the Fig. 2 with a receiving part not shown for further clarification, Fig. 4 a horizontal section through the door hinge according to the Fig. 2 , Fig. 5 a vertical section through the door hinge according to the Fig. 2 , Fig. 6 the door hinge according to the Fig. 2 in its mounted state on a door frame and a door leaf.

[0030] The functionality of the door hinge according to the invention is best understood through a comparative analysis of the Fig. 1 bis 5 , which all relate to the same embodiment of the door hinge according to the invention and show different views and details.

[0031] The Fig. 1 The diagram shows an exploded view of the door hinge, so that the individual parts are recognizable. Regarding the actual arrangement of the individual parts, the functioning of a three-dimensional adjustment mechanism, and the necessary range of motion, particular reference is made to the following sections. Fig. 2 bis 5 referred.

[0032] According to the Fig. 1 The hinge comprises a first hinge part 1 and a second hinge part 2, which are pivotally connected to each other about a vertical hinge axis 3. The hinge axis 3 runs along a vertical direction z, with the connection of the two hinge parts 1, 2 being made in a conventional manner by means of a hinge pin 4 and bushings 5. The hinge pin 4 is appropriately secured against falling out.

[0033] The second tape section 2 comprises a tape roller section 6 and an adjoining holding section 7, the holding section 7 being adjustably arranged in a receiving space 8 of a receiving part 9. The second tape section 2 is adjustable in the receiving space along the vertical direction z, along a first horizontal direction x, and along a second horizontal direction y. As further explained below, the adjustment along the second horizontal direction y is, strictly speaking, achieved by pivoting the second tape section 3 relative to the receiving part 9 about a pivot axis formed by a pivot pin 10, whereby the tape roller section 6 is then adjustable along a corresponding arc around the pivot axis, essentially along the second horizontal direction y.

[0034] For adjustment along the second horizontal direction y, the retaining section 7 has a cylindrical bore 11 in which a circular cylindrical bolt 12 is inserted. The bolt 12 has a threaded bore 13 approximately halfway along its height, which, in the assembled state, lies at the level of a vertical elongated hole 14 of the retaining section 7.

[0035] During assembly, the bolt 12 is first inserted into the associated cylinder bore 11, before a screw 15 is inserted into the threaded bore 13.

[0036] As can be seen in particular from a comparative analysis of the Fig. 1 with the Fig. 4 The screw means 15 in the compound door hinge is supported at both ends along the second horizontal direction y on an inside of the receiving space 8.

[0037] For the support and guidance of the screw element 15, a first groove 16 and a second groove 17 are arranged on the inside of the receiving space 8.

[0038] The screw element 15 is designed as a simple screw and has a head 18 with a collar 19. The second groove 17 associated with the head 18 transitions at a step 20 from a first groove section into a narrower second groove section, the collar 19 being supported on the step 20, and an inner head section 21 located within the collar 19, with a tool receptacle provided therein, lying unsupported in the second groove section. The collar 19 and the step 20 are parallel and allow for good force transmission with low wear.

[0039] Since the screw element 15 is supported at both ends not only along the second horizontal direction y, but also along the vertical direction z, the adjustment is particularly easy and largely backlash-free.

[0040] The inner head section 21 with the tool holder is accessible through an adjustment opening 22 of the receiving part 9, wherein the adjustment opening 22 is designed as a horizontal elongated hole to enable the adjustment along the first horizontal direction x described in detail below.

[0041] The adjustment along the first horizontal direction x is achieved by an eccentric arrangement comprising a barrel-shaped adjusting eccentric 23 and a pivot pin 24. During the installation of the door hinge, the adjusting eccentric 23 is initially positioned in an eccentric opening 25. When the second hinge part 2 with the retaining section 7 is then inserted into the receiving space 8 of the receiving part 9, the adjusting eccentric 23 is located at a first opening 26 and a second opening 27, each designed as a cylindrical bore but of different sizes.

[0042] During assembly, the pivot pin 24 is pressed into an axial bore of the adjusting eccentric 23, thus creating a rotationally fixed connection with the adjusting eccentric 23. A rotationally fixed connection can also be achieved through contouring.

[0043] In the illustrated embodiment, the pivot pin 24 is designed as a cylinder head screw with a shank 28 and a cylinder head 29. The pivot pin 24 is pressed in to such an extent that its ends extend into the first opening 26 and the second opening 27, where they are radially supported against the receiving part 9. This support on both sides of the pivot pin 24 ensures a permanently secure, backlash-free bearing, with the pivot pin 24 not protruding beyond the contour of the receiving part 9, but being completely enclosed by it (see in particular the figure). Fig. 4 ).

[0044] To also allow adjustment along the vertical direction z, a first setscrew 30a acts on a wedge element 31. By screwing in the setscrew 30a, the wedge element 31 is raised due to a wedge surface associated with the setscrew 30a. By unscrewing the setscrew 30a, a lowering is possible in the same way.

[0045] As shown in the figures, the arrangement of the wedge element 31 with the associated setscrew 30a below the retaining section 7 is sufficient to provide the described height adjustment, i.e., to raise or lower the second band section 2 within an adjustment range. However, an additional upper wedge element with an associated upper setscrew, not shown in the figures, can also be provided above the retaining section. After the desired height has been set, the upper wedge element can be pressed against the retaining section by tightening the upper setscrew, thereby further reducing play and improving stability. Before adjusting the height, the upper wedge element may need to be loosened, particularly if the retaining section 7 is to be raised relative to the receiving part 9.

[0046] The receiving part 9 also accommodates further grub screws 30b, with which the second band part can be locked in the desired adjustment position.

[0047] At a sufficient screw-in depth, the set screws 30b clamp the second band section 2 against the receiving part 9 in such a way that the described adjustment along the vertical direction z, as well as along the first horizontal direction x and the second horizontal direction y, is no longer possible or only possible with considerable force. Naturally, the set screws 30b should always be loosened before any adjustment.

[0048] The first band part 1, the second band part 2 and the receiving part 9 are made of metal casting, in particular zinc die casting.

[0049] Especially the Fig. 3 bis 5 illustrate the arrangement of the described parts on the assembled door hinge and their individual functions.

[0050] Thus, the support of the screw element 15 and the pivot pin 24 is in the Fig. 4 This is clearly visible in the horizontal section shown there. It is also evident that, starting from the pivot pin 10, the second band section 2 has sufficient freedom of movement along the second horizontal direction y to be adjusted, for example, by approximately + / -2° with the screw 15 along the second horizontal direction y, and strictly speaking, pivoted by a swivel angle. Accordingly, the adjusting eccentric 23 is also designed in a barrel shape to ensure the most uniform and backlash-free installation possible, despite the intended swivel movement.

[0051] From the Fig. 5 It is evident that the pivot pin 10 is movable along the first horizontal direction x in the receiving part 9, for which purpose the receiving part 9 has horizontally extending elongated holes 32. Finally, the receiving space 8 extends along the vertical direction z beyond the second belt part 2 in order to allow sufficient travel for height adjustment in the vertical direction z as well.

[0052] The Fig. 6 Finally, the figure schematically shows the mounted door hinge on a door, with the first hinge part 1 attached to a door leaf 33 and the receiving part 9 inserted into a door frame 34. Only the frame profiles of the door leaf 33 and the door frame 34 are shown.
