Description

Background of the invention

• - einen Befestigungsabschnitt zur Befestigung des Scharnierteils an einem flügelfesten Trägerteil,
• - einen Gelenkabschnitt zur drehbaren Aufnahme eines Lagerzapfens,

wobei der Befestigungsabschnitt eine erste Referenzkontur und eine zweite Referenzkontur aufweist, von denen - je nach Ausrichtung des Scharnierteils für einen Rechts- oder Linksanschlag - die eine oder die andere an einem Stützsegment des Trägerteils zur Anlage bringbar ist.The invention relates to a hinge part for a fitting for a window or a door, comprising

• - a fastening section for fastening the hinge part to a wing-fixed support part,
• - a joint section for rotatably receiving a bearing pin,

wherein the fastening section has a first reference contour and a second reference contour, of which - depending on the orientation of the hinge part for a right or left stop - one or the other can be brought into contact with a support segment of the carrier part.

Such a hinge part is made of EN 24 05 620 A1 known.

Similar fittings are often used for windows and doors to attach a sash to a respective frame for turning and opening and, if necessary, also for tilting. The frames typically consist of four frame members. For windows, four frame profiles with identical cross-sections are usually used for the two vertical and two horizontal frame members. For doors, a lower frame member is either - as with a window - with the same cross-section as the other frame members or - for a barrier-free design - with a frame member that is lower in the vertical direction, a so-called threshold. These thresholds often differ from one another in their structure and dimensions.

In order to always ensure uniform fastening conditions, the bearing pin is therefore usually attached to one of the vertical frame members - depending on the desired opening direction of the sash, to the right or left frame member. For reasons of space requirements, the bearing pin for doors with a threshold must be positioned higher relative to the upper edge of the threshold than for windows or doors relative to the upper edge of a lower frame member, which corresponds in cross-section to the other frame members. In comparison to windows or doors with similar frame members, when using a lower threshold, the sash must be lowered relative to the bearing pin in order to ensure sufficient coverage of the sash with the threshold. This is usually achieved by attaching different hinge parts, so-called hinge rollers, to the sash. Four different hinge parts have therefore been manufactured and kept in stock to cover all installation situations (left-hand stop with high lower frame member, left-hand stop with low threshold, right-hand stop with high lower frame member, right-hand stop with low threshold). This entails a correspondingly large amount of manufacturing effort, for example for individual tools.

From the above-mentioned EN 24 05 620 A1 a fitting is known in which a sash is pivotally connected to a bearing block by means of a corner hinge. The corner hinge has a profile rail, with an arm with a bearing socket for a ball pin connected to each end of the profile rail. The axes of both bearing sockets are aligned with one another, near one and the same corner of the profile rail. Accordingly, the corner hinge is designed to be mirror-symmetrical with respect to a transverse plane that intersects the common axis of both bearing sockets at a right angle, so that this corner hinge can be used for either right-hand or left-hand opening. The corner hinge can have a projection on the inside of its arms above the bearing sockets, which, when the corner hinge interacts with a corner fitting part, for example the angle housing of a corner deflection, can engage in a recess that is located near the apex in the side walls of the corner fitting part. The sash is positioned at the same height relative to a bearing block on the frame when used on the left or right.

Out of DE 72 44 357 U is a known hinge part for a sash, in particular for a tilt-and-turn sash of a window or door. The sash is connected to a fixed frame via a corner joint. This corner joint consists of a corner bearing on the frame side and the hinge part on the sash side. A hinge sleeve of the hinge part is divided into two hinge sleeve parts, each arranged starting from the narrow ends of a base plate. The two hinge sleeve parts are connected to one another by a wall arranged on the base plate, which is flush with the contour of the hinge sleeve parts. Mounting holes in the base plate are arranged in the area between the hinge sleeve parts. By turning the hinge part 180° around both its longitudinal axis and its transverse axis, it can be used for a sash hinged on the right or left. When used on the left or right, the sash is positioned at the same height relative to the corner bearing on the frame.

EP 0 896 120 A2 describes a hinge part in which a corner bearing unit is formed in the form of a corner bearing band.

Further corner bearing arrangements for an optional right or left stop are available from AT 371 550 B , AT 378 028 B , DE 20 65 970 B1 and DE 80 03 712 U known.

Object of the invention

It is an object of the invention to simplify the manufacture of fittings for use with lower frame members of different heights.

Description of the invention

This object is achieved according to the invention by a hinge part according to claim 1, a hinge assembly according to claim 9, a manufacturing method according to claim 15 and a blank according to claim 18. The respective subclaims specify preferred embodiments or variants.

Hinge part according to the invention

According to a first aspect, the invention provides a hinge part for a fitting for a window or a door. The hinge part has a fastening section for fastening the hinge part to a support part fixed to the leaf. The fastening section can have fastening holes for passing through fastening means, for example bolts. The hinge part also has a joint section for rotatably receiving a bearing pin. The bearing pin is fastened to a frame of the window or door. The bearing pin can be pivotally held on the frame to enable the leaf to be tilted. Basically, a connecting section is formed between the fastening section and the joint section, which is typically angled in itself and/or relative to the fastening section. The hinge part can also be referred to as a hinge roller.

The fastening section has a first reference contour and a second reference contour, of which - depending on the orientation of the hinge part for a right or left stop - one or the other can be brought into contact with a support segment of the carrier part. By placing the respective reference contour on the support segment, the hinge part is aligned in a defined vertical direction on the sash when assembled.

For the description of the present invention, directional information such as vertical, horizontal, up or down generally refers to a position of use with the sash mounted on the frame.

According to the invention, the joint section has a continuous longitudinal recess extending along a longitudinal axis. In other words, the longitudinal recess is a through-hole. A continuous longitudinal recess can be produced efficiently, for example by bending or rolling a flat blank. In addition, the continuous longitudinal recess makes it possible to accommodate a cylindrical bearing pin. The longitudinal recess is typically closed in the circumferential direction over at least 330°, preferably at least 350°. The longitudinal recess can have a variable diameter along the longitudinal axis. In principle, the longitudinal recess runs concentrically to the longitudinal axis over its entire length.

A first end face and a second end face limit the joint section in the direction of the longitudinal axis on the longitudinal recess. In other words, the end faces surround the longitudinal recess or the longitudinal axis in a ring shape. A minimum insertion depth of the bearing pin into the longitudinal recess is measured from the respective end face. At the same time, the end faces limit the maximum insertion depth of the bearing pin into the longitudinal recess. During use, the hinge part can be supported with one of the end faces on a collar of the bearing pin. Preferably, an adjusting screw is inserted into a thread of the longitudinal recess for fine adjustment of the height. In the assembled state, the adjusting screw can be supported directly or preferably indirectly via a pressure piece on a free end of the bearing pin.

Furthermore, according to the invention, a first distance of the first front face from the first reference contour differs from a second distance of the second front face from the second reference contour, wherein the first and the second distance are measured parallel to the longitudinal axis. Depending on whether the first or the second reference contour is brought into contact with the support segment for a right or left stop, a vertical distance of the respective lower front face from the sash-fixed support segment is changed. By turning the hinge part and mounting it on the right or left side of the sash, the height of the sash can be changed relative to the frame. In order to achieve the four installation situations mentioned above (left stop with high lower frame beam, left stop with low floor threshold, To cover the different installation situations (e.g. right-hand stop with high lower frame beam, right-hand stop with low floor threshold), only two hinge parts with different basic structures are required. Consequently, only two sets of tools, such as punching tools or forming tools, are required to produce the hinge parts or their blanks. It should be noted that the hinge parts are typically customized for one of the installation situations by post-processing, such as inserting a bearing bush or introducing a thread into the longitudinal recess. Nevertheless, the preceding manufacturing and logistics effort is significantly reduced by the design according to the invention.

Preferably, the first and second reference contours are opposite end surfaces of the fastening section. Additional processing steps for forming the reference surfaces can thereby be avoided. The fastening section is typically flat and rectangular.

Preferably, the first end face and the first reference contour as well as the second end face and the second reference contour are each oriented opposite to one another. The reference contour assigned to the lower end face then points upwards during use, so that the weight of the wing presses the support segment of the carrier part against the upper reference contour.

It can be provided that the second end face and the first reference contour are arranged at the same height in the direction of the longitudinal axis. The material consumption in the manufacture of the hinge part can thereby be reduced.

The first end face typically protrudes beyond the second reference contour in the direction of the longitudinal axis.

Advantageously, a recess is formed between the second end face and the first reference contour in a connecting section which connects the fastening section and the joint section to one another. This can help to avoid collisions. In addition, the recess can simplify the assembly of a cover cap for the joint section.

The first and second distances can differ from each other by at least 5 mm, preferably at least 7 mm, and/or by at most 20 mm, preferably at most 15 mm. This is sufficient for adaptation to low floor thresholds or high lower frame members. At the same time, these differences significantly exceed the adjustment range of adjusting screws.

A bearing bush can be inserted into the longitudinal recess on one of the end faces. The bearing bush is preferably made of plastic, while the rest of the hinge part is typically made of metal, in particular steel. The bearing bush reduces friction and reduces wear when the bearing pin engages, which is also typically made of steel.

The bearing bush basically has a cylindrical bearing bore to accommodate the (also cylindrical) bearing pin.

Preferably, the bearing bore of the bearing bush is inclined relative to the longitudinal axis of the longitudinal recess. This can counteract forces exerted by the wing. In addition, unavoidable play and manufacturing tolerances can be compensated. The inclination of the bearing bore relative to the longitudinal axis can be at least 1°, preferably at least 1.5°, and/or at most 4°, preferably at most 3°.

The bearing bore is preferably inclined in the plane of the sash. The effect of the inclined bearing bore is particularly evident when the sash is opened between 45° and 135°.

Particularly preferably, a rotational position of the bearing bush in the longitudinal recess is defined in a form-fitting manner with respect to the longitudinal axis. This ensures that the desired inclination of the bearing bore does not change as a result of the bearing bush unintentionally rotating in the longitudinal recess. For form-fitting fixation, the bearing bush can have a projection on an outer circumference which engages in a groove in the longitudinal recess. This groove can be arranged in particular at a bent end of the joint section.

Hinge assembly according to the invention

According to a second aspect, the invention also relates to a hinge assembly comprising a hinge part and a support part for fastening to a wing of a window or a door. The hinge part has a fastening section for fastening the hinge part to the support part and a joint section for rotatably receiving a bearing pin. The fastening section preferably has at least one reference contour. The hinge part is preferably a hinge part according to the invention as described above. The support part preferably has a support segment, in particular in the form of a projection. The projection basically protrudes beyond a contact surface for the fastening section. The reference contour or one of the reference contours of the hinge part can be supported on the support segment.

Preferably, the fastening section is attached to the support part with two rotatable eccentric bolts. By rotating the eccentric bolts, the hinge part can be aligned relative to the support part. In this way, the distance between the sash and the frame can be adjusted for the closed sash. This can influence the tightness of the window or door and the torque required to operate a handle.

A particularly preferred embodiment of the hinge assembly is characterized in that the support part has a vertical leg which, in an assembled state, extends along a spar axis of a vertical wing spar of the wing, and that the fastening section of the hinge part is fastened to the vertical leg of the support part in such a way that the longitudinal axis of the joint section is inclined relative to the spar axis. The spar axis basically runs parallel to the wing plane. The inclination between the longitudinal axis and the spar axis is typically set up perpendicular to the wing plane of a wing held on the hinge assembly. The effect of the inclination between the longitudinal axis and the spar axis is particularly evident when the wing is closed or opened up to 45°. This can counteract an unwanted tilting of the wing and wear of fittings. If eccentric bolts are provided, this inclination is present in particular in a zero position/basic position of the eccentric bolts. The inclination of the spar axis relative to the longitudinal axis can be at least 1°, preferably at least 1.5°, and/or at most 4°, preferably at most 3°.

It can be provided that a connecting line between centers of fastening holes in the fastening section of the hinge part runs at an angle to the longitudinal axis. In other words, at least one of the fastening holes can be offset from a center plane of the fastening section. The offset between the fastening holes can be at least 0.5 mm and/or at most 2 mm.

It can also be provided that a connecting line between centers of receiving holes in the vertical leg of the support part runs at an angle to the beam axis (and thus also to the longitudinal axis). In other words, at least one of the receiving holes can be offset from the center plane of the vertical leg. The offset between the receiving holes can be at least 0.5 mm and/or at most 2 mm.

Furthermore, it can be provided that the fastening section is fastened to the vertical leg via two rotatable eccentric bolts, each of which has a marking for a basic position, the inclination between the longitudinal axis and the beam axis being set when the eccentric bolts are in the basic position. Typically, the inclination does not disappear in any position of the eccentric bolts. In order to set the inclination of the longitudinal axis relative to the beam axis in the case of centrally arranged fastening holes and receiving holes, eccentric bolts are used in which eccentric sections are aligned differently relative to the respective marking.

The hinge assembly can further comprise a corner bearing with the preferably cylindrical bearing pin. The corner bearing can be attached to a vertical frame member of a window frame.

Preferably, the hinge assembly further comprises the frame and a sash. In this respect, the invention also relates to a window or a door. In the assembled state, the sash is hinged to the frame by means of the hinge assembly.

• - Bereitstellen einer Vielzahl identischer Rohlinge, die je einen Befestigungsabschnitt und je einen Gelenkabschnitt aufweisen, wobei der Befestigungsabschnitt eine erste Referenzkontur und eine zweite Referenzkontur aufweist, wobei der Gelenkabschnitt eine sich entlang einer Längsachse erstreckende durchgehende Längsausnehmung aufweist, wobei eine erste Stirnfläche und eine zweite Stirnfläche den Gelenkabschnitt in Richtung der Längsachse begrenzen, und wobei ein erster Abstand der ersten Stirnfläche von der ersten Referenzkontur sich von einem zweiten Abstand der zweiten Stirnfläche von der zweiten Referenzkontur unterscheidet, wobei der erste und der zweite Abstand parallel zur Längsachse gemessen werden;
• - Bearbeiten des jeweiligen Gelenkabschnitts, wobei bei einer ersten Teilmenge der Rohlinge die Längsausnehmung an der ersten Stirnfläche zur drehbaren Aufnahme eines Lagerzapfens angepasst wird und bei einer zweiten Teilmenge der Rohlinge die Längsausnehmung an der zweiten Stirnfläche zur drehbaren Aufnahme des Lagerzapfens angepasst wird.

The present invention also includes a method for producing hinge parts according to the invention as described above. The method comprises the steps

• - Providing a plurality of identical blanks, each having a fastening section and a joint section, wherein the fastening section has a first reference contour and a second reference contour, wherein the joint section has a continuous longitudinal recess extending along a longitudinal axis, wherein a first end face and a second end face delimit the joint section in the direction of the longitudinal axis, and wherein a first distance of the first end face from the first reference contour differs from a second distance of the second end face from the second reference contour, wherein the first and the second distance are measured parallel to the longitudinal axis;
• - Machining the respective joint section, wherein in a first subset of the blanks the longitudinal recess on the first end face is adapted to rotatably receive a bearing pin and in a second subset of the blanks the longitudinal recess on the second end face is adapted to rotatably receive the bearing pin.

The method according to the invention makes it possible to obtain hinge parts from identical blanks with a few simple machining operations, which can be used on the one hand (first subset) with high lower frame profiles or on the other hand (second subset) with low floor thresholds. The blanks can be obtained by punching and bending from flat material, in particular sheet metal. The same punching tools and bending tools can be used for all hinge parts produced (ie for both subsets).

The hinge parts of the first subset can be intended for a right-hand stop with a high lower frame member and the hinge parts of the second subset for a left-hand stop with a low floor threshold; alternatively, the hinge parts of the first subset are intended for a left-hand stop with a high lower frame member and the hinge parts of the second subset for a right-hand stop with a low floor threshold. In order to cover all four installation situations (left-hand stop with a high lower frame member, left-hand stop with a low floor threshold, right-hand stop with a high lower frame member, right-hand stop with a low floor threshold), the process can be repeated with further blanks that are identical to one another but mirror-symmetrical to the first blanks.

The longitudinal recess can be machined or formed on the respective end face, for example by drilling or stamping. Preferably, a bearing bush is inserted into the machined area of the longitudinal recess. In the axial direction along the longitudinal axis, the bearing bush can be held in a force-fitting and/or form-fitting manner; with regard to rotations around the longitudinal axis, the bearing bush is preferably fixed in a form-fitting manner.

A thread can be introduced into the longitudinal recess, particularly from the other end face. Preferably, an adjusting screw is screwed into the thread. In addition, a pressure piece can be inserted into the longitudinal recess, particularly before screwing in the adjusting screw. The pressure piece is arranged between the adjusting screw and the receiving area for the bearing pin, particularly the bearing bush.

Blank according to the invention

Finally, a blank for producing a hinge part according to the invention described above falls within the scope of the present invention. A large number of identical blanks according to the invention enable the previously described manufacturing method according to the invention to be carried out.

The blank has a fastening section and a joint section with a longitudinal recess extending along a longitudinal axis, wherein the fastening section has a first reference contour and a second reference contour, wherein the joint section has a continuous longitudinal recess extending along a longitudinal axis, wherein a first end face and a second end face delimit the joint section in the direction of the longitudinal axis, and wherein a first distance of the first end face from the first reference contour differs from a second distance of the second end face from the second reference contour, wherein the first and the second distance are measured parallel to the longitudinal axis.

1 shows a window 10. The window 10 has a frame 12. Sections of a vertical frame beam 14 and a lower frame beam 16 can be seen on the frame 12. An openable sash 18 is held on the frame 12. The inner or upper edges of the vertical frame beam 14 and the lower frame beam 16 covered by the sash 18 in the closed state - as shown - are shown in dashed lines. The vertical frame beam 14 and the lower frame beam 16 are formed here from similar profiles that have the same cross-section.

In the present case, the sash 18 is fitted with a right-hand stop on the frame 12. At the bottom right corner shown, a corner bearing 20 is attached to the vertical frame beam 14 with a bearing pin 22, see also 2 . For tilt-opening the sash 18, the bearing pin 22 can be pivoted about a horizontal tilt axis 24. In the window 10 shown, the tilt axis 24 is located a few millimeters, e.g. approximately 6 mm to 8 mm, below the upper edge of the lower frame member 16.

For a turning opening, the wing 18 is connected via a hinge assembly 26, compare also 3 and 4 , rotatably held on the bearing pin 22. The cylindrical bearing pin 22 engages in a longitudinal recess 54, see in particular 2 .

The hinge assembly 26 is attached to the wing 18. A support part 30 of the hinge assembly 26 is fixedly attached to the wing 18, for example screwed. A hinge part 32 of the hinge assembly 26 is attached to the support part 30.

The hinge assembly 26 is in the 5 , 6 and 7 shown in a unique position.

The support part 30 is designed here as a support angle with a vertical leg 34 and a horizontal leg 36. The support part can thus encompass a lower corner of the wing 18. The hinge part 32 is attached to the vertical leg 34 by means of two eccentric bolts 38, compare 6 as well as 3 and 4 . For this purpose, the eccentric bolts 38 pass through a fastening section 40 of the hinge part 32 and the vertical leg 34 of the support part 30. The eccentric bolts 38 enable the alignment of the hinge part 32 relative to the support part 30 to be adjusted in the horizontal direction and the hinge part 32 to be tilted about a horizontal axis that runs in the plane of the leaf.

A vertical position of the hinge part 32 on the carrier part 30 is defined by the fastening section 40 resting on a support segment 42 of the carrier part 30. The support segment 42 is designed here as a projection.

For the attachment to the support segment 42, a first reference contour 44 and a second reference contour 46 are formed on the fastening section 40, see 5 and 7 The reference contours 44, 46 are opposite end surfaces of the fastening section 40. The hinge part 32 can be fastened to the carrier part 30 in two orientations rotated by 180° to one another in order to achieve a right-hand stop (shown) or a left stop (not shown in detail). Depending on the orientation, one or the other reference contour 44, 46 comes into contact with the support segment 42.

For rotatably receiving the bearing pin 22, the hinge part 32 has a joint section 48 which is connected to the fastening section 40 via an angled connecting section 50. The joint section 50 is penetrated along a longitudinal axis 52 by the continuous longitudinal recess 54, into which the bearing pin 22 engages at one end. A base body of the hinge part 32 is designed as a stamped and bent part. The joint section 48 with the longitudinal recess 54 is obtained by bending or winding up an end region, compare in particular 6 .

In the direction of the longitudinal axis 52, the joint section 48 is delimited by a first end face 56 and a second end face 58, which extend perpendicular to the longitudinal axis 52 in a ring shape around the longitudinal recess 54. In the embodiment shown, the hinge part 32 is customized for the right-hand stop by inserting a bearing bush 60 from the first end face 56 into the longitudinal recess 54, see in particular 7 and the 8th and 9 which show the bearing bush 60 in its unique position.

In order to limit the insertion depth of the bearing pin 22 into the longitudinal recess 54 and thus to finely adjust the height of the sash 18 relative to the frame 12, an adjusting screw 62 is screwed into a thread 64 of the longitudinal recess 54 from the second end face 58, see 7 and 2 The adjusting screw 62 is supported here by a pressure piece 66 on the bearing pin 22, see in particular 2 .

A bearing bore 68 in the bearing bush 60 is inclined relative to the longitudinal axis 52, see 7 and particularly 9 . An angle between a bearing bore axis 70 of the bearing bore 68 and the longitudinal axis 52 can be 2°. In the present case, the bearing bore 68 is inclined in the plane of extension of the wing 18 (wing plane), from its lower end towards the wing 18.

In order to establish a defined rotational position of the bearing bush 60 in the hinge part 32, a projecting rib 72 of the bearing bush 60 (see 8th ) into a groove 74 (compare 6 ) which extends along the longitudinal recess 52 on the joint portion 48.

In addition, the bearing bush 60 can be held in the longitudinal recess 52 in a force-fitting manner. For this purpose, clamping lugs 76 can be provided on the outer circumference of the bearing bush 60, see in particular 8th .

The above-mentioned end faces 56, 58 on the joint section 48 are spaced at different distances from their associated reference contours 44, 46 on the fastening section 40. A first distance 78 of the first end face 56 from the first reference contour 44 is greater by a height offset 80 than a second distance 82 of the second end face 58 from the second reference contour 46, compare 5 The height offset 80 is 9 mm.

If the hinge part 32 were to be fastened to the support part 30 rotated by 180° for a left-hand stop (the bearing bush 60 would then have to be inserted into the longitudinal recess 54 on the second end face 58), the sash 18 would thus be arranged lower on the frame 12 relative to the bearing pin 22 or its tilt axis 24 by the amount of the height offset 80.

In the present case, the second end face 58 is aligned flush with the first reference contour 44 in the direction of the longitudinal axis 52. A recess 84 is formed in the connecting section 50 between the second end face 58 and the first reference contour 44. The first end face 56 protrudes relative to the second reference contour 46 in the axial direction with respect to the longitudinal axis 52. The recess 84 or the projection makes it easier to attach a cover cap (not shown in detail) to the hinge part 32.

10 shows a door 86, which in its basic structure corresponds to the window 10 of 1 The differences are primarily described below; otherwise, reference is made to the above description.

In the door 86, a lower frame member is designed as a floor threshold 88, which has a lower cross-section than a vertical frame member 14. This is shown in the 10 indicated by dashed lines and in 11 , which shows the frame 12'. The corner bearing 20 with the bearing pin 22 attached to the vertical frame beam 14 is therefore in comparison to the window 10 of 1 arranged higher relative to the upper edge of the floor sill 88. The tilting axis 24 of the bearing pin 22 is located slightly (a few millimetres, e.g. approx. 1 mm to 3 mm) above the upper edge of the floor sill 88, compare 10 . The sash 18 must therefore be positioned lower relative to the corner bearing 20 when using the floor threshold 88 than when using the high lower frame beam 16 (compare 1 ).

At door 86 of 10 is like window 10 of 1 A right stop is provided. A 12 The hinge assembly 26 shown therefore has a hinge part 32' which corresponds to the hinge part 32 of 5 is mirror-symmetrical. For a right-hand stop with the low floor threshold 88, the hinge part 32' is supported with its second reference contour 46 on the support segment 42 of the carrier part 30. The bearing pin 22 is introduced into the longitudinal recess 54 on the second end face 58. The bearing bush 60 is therefore arranged on the second end face 58 in the longitudinal recess 54.

For a left-handed door with a low threshold (not shown in detail), the hinge part 32 would be 5 to be fastened to the carrier part 30 rotated by 180° so that its second reference contour 46 comes to rest on the support segment 42 and the position bolt 22 engages in the longitudinal recess 54 on the second end face 58. The bearing bush 60 would be inserted accordingly on the second end face 58.

Accordingly, for a left-hand stop of a window with a high lower frame beam (not shown in detail), the hinge part 32' of 12 to be fastened to the carrier part 30 rotated by 180° so that its first reference contour 44 comes to rest on the support segment 42 and the position bolt 22 engages in the longitudinal recess 54 on the first end face 56. The bearing bush 60 would be inserted accordingly on the first end face 58.

The invention thus makes it possible to cover four different installation situations (right stop with high lower frame member 16, left stop with low floor threshold 88, left stop with high lower frame member 16, right stop with low floor threshold 88) by using two hinge parts 32, 32' accordingly. Before final machining of the longitudinal recess 54, in particular the insertion of a bearing bush 60, the hinge parts 32, 32' are each suitable for two of these installation situations. The first design (the hinge part 32) can be used for a right stop with high lower frame member 16 or a left stop with low floor threshold 88; the second design (the hinge part 32') can be used for a left stop with high lower frame member 16 or a right stop with low floor threshold 88. After final machining, the hinge parts 32, 32' are customized for one of the installation situations.

13 shows another installation option for the hinge assembly 26 with the hinge part 32. In the manner described above, the hinge part 32' could alternatively be used. The carrier part 30 is here part of a corner deflection 90. The support segment 42 is embossed from the carrier part 30 so that it protrudes from it.

Especially in 4 it can be seen that the longitudinal axis 52 of the longitudinal extension 54 is inclined relative to a vertical spar axis 92 of a vertical wing spar 94 to which the support part 30 is attached. In particular, when the wing 18 is closed or opened in a rotational manner, the spar axis 92 typically runs in a vertical direction; when the wing 18 is tilted open, the spar axis 92 is inclined accordingly in space.

The vertical leg 34 of the support part 30 extends along the vertical spar axis 92. An angle between the longitudinal axis 52 and the vertical spar axis 92 can be 2°. In the present case, the longitudinal axis 52 is inclined perpendicular to the plane of extension of the wing 18 (wing plane), specifically from its lower end away from the wing 18.

This inclination of the longitudinal axis 52 relative to the vertical spar axis 92 can be arranged in different ways.

According to 14 Receiving holes 96 for bolts, in particular eccentric bolts 38, in the vertical leg 34 of the support part 30 can be offset from one another transversely to the beam axis 92. A horizontal offset 98 between the receiving holes 96 can be 1 mm.

According to 15 Fastening holes 100 for passing through bolts, in particular eccentric bolts 38, in the fastening section 40 can be offset from one another transversely to the longitudinal axis 52. A horizontal offset 102 between the fastening holes 100 can be 1 mm.

Furthermore, according to 16 Eccentric bolts 38 with a concentric section 104 and an eccentric section 106 can be used. The concentric sections 104 here engage in fastening holes in the hinge part 32, 32'; the eccentric sections 106 here engage in receiving holes in the carrier part 30. The eccentric bolts 38 can be riveted to the carrier part 30 at the free end of the eccentric sections 106.

The eccentric section 106 of at least one of the eccentric bolts 38 is aligned with respect to markings (for example an embossed line 108a or a flattening 108b on a head 110) which indicate a basic position, such that an inclination of the longitudinal axis 52 relative to the vertical beam axis 92 is established when both eccentric bolts 38 are in the basic position. For this purpose, two eccentric bolts 38 with different alignments of the eccentric section 106 relative to the markings 108a, 108b are always used. In 4 The basic position is shown in which the embossed lines are aligned vertically and the flats are aligned horizontally.

17 shows a flow chart of a method for producing hinge parts 32 or 32'.

First, in a step 202, a large number of identical blanks are provided. The blanks are intended either to be further processed into hinge parts 32 or hinge parts 32'. The blanks already correspond essentially in their structure to the hinge parts 32 or 32'. In a first process run (with first blanks), hinge parts 32 can be produced which are customized as part of the process for one of the installation situations (e.g. high lower frame member 16 with right-hand stop or low floor sill 88 with left-hand stop). In a second process run (with second blanks which are mirror-symmetrical to the first blanks), hinge parts 32' can be produced which are customized as part of the process for one of the other installation situations (e.g. high lower frame member 16 with left-hand stop or low floor sill 88 with right-hand stop).

In particular, the blanks each have a fastening section 40 and a joint section 48. The fastening section 40 has a first reference contour 44 and a second reference contour 46. The joint section has a continuous longitudinal recess 54 extending along a longitudinal axis 52. A first end face 56 and a second end face 58 delimit the joint section in the direction of the longitudinal axis. A first distance 78 of the first end face 56 from the first reference contour 44 differs from a second distance 82 of the second end face 58 from the second reference contour 46.

The blanks are divided into two subsets. For the blanks of the first subset, in a step 204-1 the joint section 48 adjacent to the first end face 56 is machined to rotatably receive a bearing pin 22. For the blanks of the second subset, in a step 204-2 the joint section 48 adjacent to the second end face 58 is machined to rotatably receive a bearing pin 22. The machining can be carried out by machining, for example by drilling, or by forming, for example by embossing. In steps 204-1 and 204-2, a thread 64 is typically also introduced into the longitudinal recess 50, for example cut or formed. The thread 64 can in particular be produced starting from the end face which faces away from the machined region of the longitudinal axis 54.

Preferably, in a step 206, a bearing bush 60 is inserted into the longitudinal recess 54 at the respective machined end. In a step 208, a pressure piece 66 can be inserted into the longitudinal recess. In a step 210, an adjusting screw 62 is then screwed into the thread 64. The pressure piece 66 is arranged between the bearing bush 60 and the adjusting screw 66.

In summary, the invention relates to a hinge part and a blank for producing the hinge part. On the blank and the hinge part, opposing end faces are spaced at different distances from associated reference contours on a longitudinal recess. In the hinge part, the longitudinal recess is designed on at least one of the end faces for rotatably receiving a bearing pin. A wing can be aligned in a defined vertical direction on the hinge part via a support segment, which can be formed on a carrier part. Depending on which of the end faces the bearing pin is inserted into the longitudinal recess, the vertical position of the wing relative to the bearing pin is changed.
