Description

The invention relates to a door hinge and a door arrangement. The invention is based on a door hinge for building doors with a first hinge part and with a second hinge part connected to the first hinge part so that it can pivot about a hinge axis. The second strap part has a first adjustment partner and a second adjustment partner that is detachably connected to the first adjustment partner.

In particular, the invention assumes that the first hinge part is connected to a door frame or to a door frame and the second adjustment partner is connected (directly or indirectly) to a door leaf. The first adjustment partner creates the connection between the second adjustment partner and the first strap part, in particular in the main force circuit.

Particularly high-quality door hinges have already been designed in the past in such a way that a relative adjustment in one or more spatial axes is made possible between the first hinge part and the second hinge part. In particular, one assumes an adjustment possibility in the direction of the hinge axis (height adjustment), an adjustment in the normal direction of the closed door leaf (pressure adjustment) and a lateral adjustment, the adjustment direction of which is aligned perpendicular to the height and pressure adjustment. Due to the increased design effort and the high demands on the dimensional tolerances, such adjustment options have so far been reserved for particularly high-quality and expensive door hinges.

The present invention is based on an adjustment when two adjustment partners - in this case in particular the first adjustment partner on the one hand and the second adjusting partner, on the other hand, can be fixed (locked) or made movable (mobilized) with respect to one another by technical measures with regard to a relative movement. In contrast to a mere adjustment, it is also provided with an adjustment that the adjustment partners can be moved into a defined position (adjustment position) using technical means. This enables a particularly precise adjustment of the door hinge in one or more spatial directions. A correct setting of the position of the door hinges serves to compensate for production tolerances and the setting behavior of the material of the door leaf and door frame, thereby ensuring that the door functions optimally.

In the case of previous door hinges, solutions based on spindle drives, eccentric cams and special toothed and/or worm gears are known as adjustment means. Such solutions require a high design and manufacturing effort. Accordingly, such solutions are not common in particularly inexpensive door hinges. If an adjustment option is provided for these at all, this only provides an option for loosening and fixing two adjustment partners. The actual displacement must then be achieved by applying force to the adjustment partner or to the door leaf. Since this indirect form of adjustment is not applied directly to the adjustment partners, only a lower adjustment accuracy can be achieved due to the play between individual components.

Out of DE 20 2014 100 431 U1 discloses a generic door hinge.

Out of EP 1 619 337 A2 is an adjustment mechanism with a first adjustment partner and a second adjustment partner, both the first Adjustment partner and the second adjustment partner each have a slot with a tooth profile arranged on one side. An actuating element in the form of a toothed wheel is arranged in between to provide the adjustment.

Against this background, the invention is based on the object of specifying a particularly cost-effective door hinge with a cost-effective and at the same time precise adjustment option. The subject matter of the invention and the solution to this problem is a door hinge according to claim 1 and a door arrangement according to claim 15. Preferred configurations are specified in the dependent claims.

According to the invention, it is provided that the first adjustment partner can be adjusted relative to the second adjustment partner in a first adjustment direction. In this case, a first opening is formed in the first adjustment partner and a second opening arranged overlapping with the first opening is formed in the second adjustment partner. The first opening and/or the second opening are designed as a slot aligned in the first adjustment direction with a tooth profile formed on one side.

In particular, the first opening and the second opening have the same opening width transversely to the second adjustment direction—which is locally reduced by the tooth profile.

The overlapping area of the first opening and the second opening is free, so that an adjustment tool that is not included in the door hinge can be inserted into this area. In order to actuate the adjustment according to the invention, it is provided that the adjustment tool is inserted into the first opening and the second opening and rotated. Here, the adjustment tool with a the tooth profile cooperating outer profile. For this purpose, the tooth profile is adapted in particular to the outer profile of the adjustment tool. In particular, the door hinge has no additional transmission part for force transmission between the first opening and the second opening. This can be effected entirely by the adjustment tool.

A regular tool such as an external hexagon (trade name: Inbus) or an external hexalobe (trade name: Torx) can expediently be used or provided as the adjustment tool. However, other types of profiles such as external triangular or square as well as star or gear-shaped profiles (with any number of teeth) are also possible.

The adjustment according to the invention is based on the principle that the adjustment tool is inserted into the first opening and into the second opening and its outer profile engages with the one-sided tooth profile of the elongated hole. A linear adjustment movement in the direction of the extent of the elongated hole—in particular a lateral adjustment—is caused by a rotary movement of the adjustment tool. The elongated hole serves as a guide and, with its toothed profile, as a toothed rack.

Within the scope of the invention, an adjustment gear is provided solely on the basis of the first adjustment partner and the second adjustment partner. These can also be produced particularly simply, i.e. in particular as pieces of sheet metal. Additional gears, levers and the like, which are complex to design, manufacture and assemble, are eliminated; the first opening and the second opening remain free.

A preferred combination provides a circular hole in connection with the slotted hole toothed on one side. The circular hole is preferably on the side facing the user - that is in particular as a second opening on the second adjustment partner - arranged so that the toothed elongated hole is protected behind it as the first opening and is accommodated in a concealed manner on the first adjustment partner.

A combination of two elongated holes aligned in parallel and toothed on opposite long sides is also possible. In this case, the adjustment movement takes place with a particularly large adjustment path, the axis of rotation of the adjustment tool shifting as a result of the rotary movement in relation both to the first adjustment partner and to the second adjustment partner.

The second adjustment partner is preferably made from a piece of sheet metal and is designed to be adjustable relative to the first adjustment partner. Due to the production from a piece of sheet metal, the second adjustment partner is reduced to the structurally required minimum. Sheet metal pieces can be brought into the desired configuration inexpensively and in large quantities by cold or hot forming. By selecting the sheet thickness, the use of material - and the associated material costs - and the desired load capacity can be flexibly coordinated in a particularly simple and efficient manner. It is particularly advantageous that the second adjustment partner itself does not have to have any special provisions for adjustability or adjustability. In the context of the invention, it is provided in particular that the relative translational adjustment takes place in one and preferably at least two spatial axes exclusively at the interface between the first adjustment partner and the second adjustment partner.

Within the scope of the invention, the second strap part is designed in two parts with the two adjustment partners. The first adjustment partner (also referred to as the carrier) is fixed (directly or indirectly) to a door leaf or door frame and the second adjustment partner (also referred to as the hinge bracket), which can be adjusted in comparison, is arranged in the main force connection between the first adjustment partner and the rotatable connection to the first hinge part .

It is preferably provided that the first band part is also made from a piece of sheet metal. As a result, the manufacturing advantages can also be realized on the first band part. The manufacturing process of several sheet metal components can also be combined and linked so that a uniform material appearance can be achieved.

According to a particularly preferred embodiment, the first adjustment partner also has a piece of sheet metal which is received and mounted in at least one assigned receptacle of the first hinge part so that it can rotate. With a suitable configuration of the geometry of the first adjustment partner, stable and functional hinge brackets can also be provided at low cost. In particular, the first adjustment partner is made entirely from a piece of sheet metal.

The first adjustment partner is preferably provided with at least one attachment--particularly made of plastic--which is placed on the piece of sheet metal and engages in the receptacle of the first hinge part. In order to reduce the friction that occurs during a rotary movement, the attachment can be coated or at least partially made of it, in particular with a low-friction material, for example PTFE.

According to a particularly preferred embodiment, the piece of sheet metal has a projection at two opposite ends in the direction of the hinge axis (axial direction)—particularly covered by an attachment—which engages in an assigned upper or lower receptacle of the first hinge part. Due to the two-sided axial bearing, the second strap part, in particular the first adjustment partner, can be captively accommodated on the first strap part.

Preferably, the upper receptacle and the lower receptacle on the first strap portion are configured such that they can be flexed apart for insertion of the second strap portion. This is possible in particular with a first band part made from a sheet metal part. For this purpose, freely overhanging projections can preferably be arranged on the first band part, which at least partially contain the two receptacles.

In order to reliably prevent the second band part from falling out during operation, a holding element is expediently arranged between the cantilevered projections, which holds the two projections together in the axial direction.

The holding element is preferably designed as a metal strip through which extensions formed on the projections pass. Particularly expediently, the extensions can be mushroomed for captive locking of the holding element.

According to a preferred embodiment, the first hinge part has at least one support surface which is perpendicular to the hinge axis and on which the attachment—at least in certain closed states—has crashed. Included the attachment (for example with an extension) lies in a form-fitting manner on the support surface and thus enables an additional transmission of axial loads (acting in the axial or vertical direction) as well as tilting moments acting on the door hinge. The support surface and/or the area of the attachment in contact with the support surface are preferably also provided with a low-friction material.

In the context of the invention, it is particularly preferred that the first adjustment partner is connected to the second adjustment partner by at least one fastening means, in particular a screw connection. The fastening means can preferably also be used to brace the two adjustment partners (in particular the carrier and the hinge bracket) against one another, at least in one direction. This bracing serves in particular to lock the two adjustment partners against one another and to prevent an adjustment movement. The adjustment partners can be mobilized towards one another by (partially) loosening the fastening means.

An internal thread is particularly preferably provided on an adjustment partner, in which an associated clamping screw engages. The respective other adjustment partner has an associated opening - in particular a slot - through which the clamping screw reaches and supports the clamping screw (e.g. on a clamping screw head) in its axial direction.

In an alternative embodiment, the internal thread for the clamping screw can also be formed independently of the two adjustment partners on a counterpart—in particular a nut. Particularly preferably, the at least one fastening means can be actuated by the same adjustment tool that is adapted to the tooth profile. In particular, screws with an adapted hexagon socket or hexalobular socket profile come into consideration here. This makes it possible for an operator to first loosen the fastening means (in particular clamping screws) with the adjustment tool, ie relax them, so that the relative mobility between the first adjustment partner and the second adjustment partner is established. The adjustment tool can then be guided through the two openings and the adjustment according to the invention in the first adjustment direction (in particular lateral adjustment) can be actuated by means of a rotary movement.

In a preferred embodiment, the first adjustment partner has a first contact surface and the second adjustment partner has a second contact surface, which faces the first contact surface and is aligned parallel to it. The first contact surface and the second contact surface are particularly preferably flat and aligned in such a way that the common surface normal is perpendicular to the hinge axis. The door hinge is adjusted - between the first adjustment partner and the second adjustment partner - by a relative change in position of the two contact surfaces. It is preferably provided that the relative mobility of the two contact surfaces can be determined by the fastening means (in particular screw connection).

According to a particularly preferred embodiment of the invention, it is provided that at least one - in particular sheet metal - spacer is arranged between the first contact surface and the second contact surface, through which the minimum distance between the first contact surface and the second contact surface is in a second (perpendicular to the first contact surface and the second contact surface aligned) Horizontal direction is fixed. By selecting the number and material thickness of the spacers inserted between the first contact surface and the second contact surface, the minimum distance can be set flexibly over a wide range of parameters (for example between 0 mm and about 10 mm). The setting position of the door hinge in the second adjustment direction—in particular a second horizontal direction—is clearly defined by the appropriate selection of the spacer(s). This is reliably assumed after tightening the fasteners or clamping screws. Due to the preferred orientation of the second adjustment direction perpendicular to the hinge axis, a change in distance between the first contact surface and the second contact surface is almost independent of the weight force acting on a door leaf connected to the door hinge.

In addition to the claimed variants of the door hinge according to the invention, it is also conceivable to provide a system for providing a door hinge (door hinge system). This includes a set of one or more spacers, which can be introduced alternatively and/or cumulatively between the first contact surface and the second contact surface.

The set of spacers particularly preferably has at least two spacers of different material thicknesses. Very particularly preferably, some, in particular all of the spacers have a material thickness ratio of 1:2 to one another. This grading enables a precise setting with an increment that corresponds to the material thickness of the thinnest spacer in each case.

Alternatively or additionally, the door hinge system includes a set of multiple carriers. The straps are for attaching the second strap part to a Door frames or door leaves provided and have a different geometry from each other, which is adapted to different shapes of door frames or door leaves. In particular, the carriers are adapted to hollow chamber profiles of different profile dimensions and/or manufacturers. This makes it possible to adapt the existing door hinge to different installation situations by carefully selecting a suitable carrier. A particularly light design of the door hinge for the intended purpose is thus achieved, with the majority of the components used remaining the same and therefore being able to be flexibly used or reused in different application scenarios. The carrier or carriers can in particular also simultaneously form the second adjustment partner according to the invention.

The carrier (second adjustment partner) is expediently designed as a sheet metal profile with one or more angles, which has at least one contact leg to form the second contact surface and one or more fastening legs angled in the opposite direction for fastening—in particular to a hollow chamber profile. Optionally, it can also be provided that the carrier (second adjustment partner) has a support leg which is angled relative to the contact leg and which is bent in a different direction than the fastening leg or legs. The support leg is preferably aligned parallel to the fastening leg or legs. Depending on the configuration of the associated fastening surface (in particular on a hollow chamber profile), the fastening leg or legs can be arranged flush with the surface or offset parallel to the support leg. Due to the optimal adaptation to the intended fastening surface, particularly high supporting forces can be transmitted - even with an inexpensive sheet metal part.

For further adaptation to possible profile shapes - in particular for adaptation to a small profile depth - spacer plates can also be arranged on the first hinge part, which are arranged between a fastening flange of the first hinge part and an associated fastening surface on a door frame or door leaf - in particular a hollow chamber profile. Due to the spacer plates, the first hinge part, and thus the hinge axis, penetrates less deeply into the fastening surface, so that a smaller hinge mount arranged behind it is sufficient.

Furthermore, it is preferably provided that a guide pin, which is aligned in the normal direction of the contact surfaces and engages in an associated guide recess of the first adjustment partner, is arranged on the second adjustment partner. Alternatively or additionally, a guide pin aligned in the normal direction of the contact surfaces can be formed on the first adjustment partner, which engages in an associated guide recess of the second adjustment partner. The guide pin(s) are preferably designed to be essentially cylindrical with a cross section that is constant in the normal direction.

In order to provide the guide function, it is preferably provided that the guide pin bears against and is supported on the respectively assigned recess in at least one spatial direction. This provides positive guidance and limits the relative mobility of the two adjustment partners in at least one spatial direction. By aligning the guide pins in the normal direction, they enable at least one adjustment movement in the second adjustment direction (normal direction).

In addition, the recesses can particularly preferably be designed as elongated holes aligned in the first adjustment direction (first horizontal direction). be so that an adjustment movement in the first adjustment direction is also not impeded by the positive guidance of the guide pins. It is particularly preferably provided that at least one slot-shaped recess is formed with a closed edge, so that the adjustment path in the first adjustment direction is limited.

According to a preferred embodiment, it is provided that the guide pin or pins are formed by material deformation of the (particularly sheet metal) first adjustment partner or second adjustment partner. In particular, the guide pin or pins can be stamped into the material.

Alternatively, it is also conceivable to provide the guide pin(s) as separate parts and to connect them to the first adjustment partner or the second adjustment partner—in particular to weld or rivet them.

In variants with one or more spacers for insertion between the contact surfaces, it is provided that the at least one spacer—preferably all spacers provided—has at least one elongated hole open on one side for insertion between the first adjustment partner and the second adjustment partner. Particularly preferably, a plurality of parallel-aligned elongated holes open on one side are provided, which are provided as required for receiving a fastening means, at least one guide pin and/or an adjustment tool.

It is particularly preferably provided that the one or more spacers - without considering the one or more elongated holes - covers at least 90% of the area, preferably essentially the entire area, of the first bearing surface and the second bearing surface.

For better handling, provision can preferably be made for one or more spacers to protrude at least slightly—in particular between 1 mm and 4 mm—in the (maximally inserted) assembly position between the first adjustment partner and the second adjustment partner. As a result, the spacers are accessible and can also be removed from the gap again. Particularly preferably, a possibility of gripping—in particular a gripping hole or a recessed grip—is formed at least in the protruding area.

For the setting in a third adjustment direction - parallel to the axis of rotation - it is expedient to provide that elongated holes are arranged on the first strap part and/or the second adjustment partner (or carrier) in the direction of the hinge axis - i.e. in particular in the vertical direction - through which Fastening means for attachment to a door frame or a door leaf can be passed. As a result, an adjustment option in the height direction is added. As a result of the precise adjustment in two horizontal directions made possible within the scope of the invention, a coarser adjustment option in the vertical direction is acceptable.

A further aspect of the invention relates to a door arrangement with a door frame and a door leaf held on the door frame. According to the invention, the door frame and the door leaf are pivotally connected to one another by at least one door hinge described above, which is available in particular as part of a door hinge system according to the invention. Here are the first band part with the door frame and the second Adjusting partner rigidly coupled to the door leaf - in particular directly connected. Since the second adjustment partner has to provide a purely fastening or adapter function between the door construction and the first adjustment partner, it can be designed in a particularly simple and filigree manner. It is therefore particularly suitable for an arrangement on the door leaf.

The subject matter of the invention is also a door hinge system with a door hinge according to the invention as described above and at least one adjusting tool which can be pushed into the first opening and the second opening. The adjustment tool interacts with the tooth profile according to the invention by a rotary movement, so that a relative adjustment between the first adjustment partner and the second adjustment partner in the adjustment direction is effected.

The invention is explained below with reference to figures that merely represent exemplary embodiments. They show schematically:

the 1 shows an exploded view of a door hinge 1 according to the invention for building doors with a first hinge part 2 and one by one Hinge axis x pivotably connected to the first hinge part 2 second hinge part 3. The first hinge part 2 has in the direction of the hinge axis x on the top and bottom in each case a contact flange 4 with slots 4a arranged therein. In the exemplary embodiment, the contact flanges 4 are intended to fasten the first hinge part 2 to a door frame or a door frame.

The second strap part 3 has a hinge bracket which is pivotably connected to the first strap part 2 and forms a first adjustment partner 5 , and a carrier which forms a second adjustment partner 6 . The first adjustment partner 5 and the second adjustment partner 6 are connected to one another in a clampable and detachable manner by fastening means in the form of two clamping screws 7 . For this purpose, the clamping screws 7 oriented in a second horizontal direction y reach through associated slots 6a of the second adjustment partner 6 and each engage in an associated internal thread 5a of the first adjustment partner 5 . In the exemplary embodiment, the clamping screws 7 are designed with a hexalobular socket for receiving an adjustment tool (not shown). The invention provides that the first adjustment partner 5 and the second adjustment partner 6 are designed to be adjustable in relation to one another.

According to the present exemplary embodiment, the second adjustment partner 6 is made from a piece of sheet metal. Likewise, the first band part 2 is made from a piece of sheet metal. In this case, a receiving space is enclosed by folding over the metal sheet, into which the hinge bracket or first adjustment partner 5 dips during a closing movement. Further sections of the piece of sheet metal are bent over to form the contact flanges 4 .

In the exemplary embodiment shown, the first adjustment partner 5 is also designed as a piece of sheet metal. The first adjustment partner 5 has projections 5b, which are received in assigned receptacles 2a of the first strap part 2 so that they can rotate. In order to reduce friction, attachments 8 made of a low-friction material are arranged between the projections 5b and the receptacles 2a. The attachments 8 each have a cylindrical cap 8a, which dips into the circular receptacles 2a in a form-fitting manner.

Furthermore, the first hinge part 2 has supporting surfaces 2b which are perpendicular to the hinge axis x or the vertical direction and on which the attachments 8 are supported. For this purpose, the attachments 8 have, on the one hand, a collar surface 8b surrounding the cylindrical cap 8a and a radially projecting arm 8c that has crashed onto the piece of sheet metal of the first adjustment partner 5 .

The first adjustment partner 5 has a first planar contact surface 9a, which extends perpendicular to the second horizontal direction y. The second adjustment partner 6, on the other hand, has a second planar contact surface 9b, which faces the first contact surface 9a and is aligned parallel to it.

For adjustment in the second horizontal direction y, at least one sheet-metal spacer 10 is arranged between the first contact surface 9a and the second contact surface 9b. The minimum distance between the first contact surface 9a and the second contact surface 9b in the second horizontal direction y is defined by the spacer 10 . By tightening the clamping screws 7 in this second horizontal direction y, the first adjustment partner 5 and the second adjustment partner 6 are brought closer to one another in such a way that they assume this minimum distance.

To change the adjustment position in the second horizontal direction y—or the second adjustment direction—the material thickness and/or the number of spacers between the first contact surface and the second contact surface can be varied. In the 1 a second spacer 10' is indicated by dashed lines. This is designed identically to the first spacer 10 purely by way of example. Likewise, an alternative spacer can also be designed with a different material thickness (in the second horizontal direction y).

When assembling the door hinge, it is provided that the attachments 8 are placed on the projections 5b of the first adjustment partner 5. The first strap part 2 is then bent apart in the areas forming the receptacles 2a and the support surfaces 2b in order to insert the first adjustment partner 5 with the attachments 8 .

In order to prevent removal of the second hinge part 3 from the first hinge part 2 after the complete assembly of the door hinge, the sheet metal parts of the first hinge part 2 forming the receptacles 2a are held together by a sheet metal strip 11 in the direction of the hinge axis x. For this purpose, the metal strip 11 has receiving holes 11a, through which projections 2c of the first band part 2 can be inserted. For the final fixation, the projections 2c are forked at the end, so that they can be mushroomed. As a result, they are oversized in relation to the passage openings 11a and engage behind the metal strip 11. In the exemplary embodiment shown, the metal strip 11 also serves as a stop on the closing side for the arms 8c of the caps 8. This establishes a defined end position for the closing pivoting movement.

According to the invention, the first adjustment partner 5 is designed to be adjustable relative to the second adjustment partner 6 in a first adjustment direction z—or first horizontal direction—aligned parallel to the first contact surface 9a and the second contact surface 9b. A first opening 5c is formed in the first adjustment partner 5 and a second opening 6b is formed in the second adjustment partner 6, which opening is arranged so that it overlaps the first opening 5c.

In the exemplary embodiment shown, the first opening 5c is designed as an elongated hole aligned in the first adjustment direction z, which is designed with a tooth profile 12 on one side—along a longitudinal edge. The tooth profile 12 has a shape which, together with an adjusting tool having an external hexalobular profile, forms a rack and pinion gear. The rotational movement of this matching adjustment tool—which is also suitable for loosening and tightening the clamping screws 7—is converted into a linear movement in the first adjustment direction z by means of the toothed profile 12 . The circular second opening 6b on the second adjustment partner 6 serves as an abutment. An adjustment tool inserted through the first opening 5c and the second opening 6b can thus be used for horizontal adjustment in the first adjustment direction z.

Two guide pins 13 are arranged on the first adjustment partner 5 to guide the second adjustment partner 6 both in the first adjustment direction z and in the second adjustment direction y. The guide pins 13 are embossed in the sheet metal material of the first adjustment partner 5 and protrude cylindrically symmetrically on the first contact surface 9a in the second horizontal direction y. The guide pins 13 go through this Spacer 10 and engage in a form-fitting manner in associated guide recesses 14 in the second adjustment partner 6 .

In order to enable mobility in the first adjustment direction z, the guide recesses 14 are designed as elongated holes aligned in this first horizontal direction z. In the exemplary embodiment shown, one guide recess 14 is in the form of a closed-edged slot and the other guide recess 14 is in the form of an open-edged slot. The outer diameter of the cylindrical guide pins 13 essentially corresponds to the transverse extent of the two guide recesses 14 in the direction of the hinge axis x—that is, transversely to the first adjustment direction z.

For insertion between the first adjustment partner 5 and the second adjustment partner 6, the spacer 10 has a plurality of open-edged elongated holes 10a for receiving the clamping screws 7 or the guide pins 13. As a result, one or more spacers 10 can be inserted between the first contact surface 9a and the second contact surface 9b without the first adjustment partner 5 and the second adjustment partner 6 having to be separated from one another. Another elongated hole 10b for passing the adjusting tool through between the first opening 5c and the second opening 6b can be designed with closed edges, as shown in the exemplary embodiment.

The second adjustment partner 6 has a contact leg 6c, on the surface of which the second contact surface 9b is formed. Beveled fastening legs 6d are thus formed of the same material, with which the second adjustment partner 6 can be fastened as a support on a door leaf 17 or a door frame. For this purpose, passage openings 15 for fastening screws are formed in the fastening legs 6d Enabling height adjustment and/or hanging in the form of slots aligned in the direction of the hinge axis x.

That in the 1 illustrated door hinge according to the invention is in the Figure 2A shown as part of a door assembly according to the invention in the central horizontal section. The first hinge part 2 is mounted on a door frame 16 designed as a hollow chamber profile and the support or second adjustment partner 6 on a door leaf 17 also designed as a hollow chamber profile. The first hinge part 2 rests with the contact flanges 4 on an associated mounting surface 16a of the frame profile 16 and is screwed to it through the slots 4a. If a variation of the installation depth of the first hinge part 2 on the frame profile 16 is required, one or more - in 1 spacer plates 18 indicated by dashed lines are inserted between the contact flanges 4 and the mounting surface 16a.

Likewise, the second adjustment partner 6 rests with the fastening legs 6d on an assigned mounting surface 17a of the wing profile 17 . The contact leg 6c and the mounting leg 6d are folded against each other at a right angle. The sectional view also shows that the contact leg 6c is also adjoined by a support leg 6e, which is also bent away from the fastening legs 6d at a right angle. The fastening leg 6d and the support leg 6e are aligned parallel to one another and are flush with the mounting surface 17a.

Furthermore, you can see from the illustrations Figure 2A and 2 B that the clamping screws 7 are each held captive by a snap ring 19 on the first adjustment partner 5 .

In the Figure 2B An alternative form of door assembly is shown. This has a different door frame profile 16' and an adapted door leaf profile 17'. A comparative view of Figures 2A and 2 B it can be seen that the hinge bracket or first adjustment partner 5 and the first hinge part 2 are of identical design. To adapt to the modified hollow profile 17', only an adapted carrier or second adjustment partner 6' is provided. This alternative second adjustment partner 6 'has compared to the variant of Figure 2A a shortened attachment leg 6d' and an extended support leg 6e'.
