[0004] Band arrangement
[0005] The invention relates to a hinge arrangement, in particular a concealed hinge arrangement for the rotatable attachment of a door or window sash to a door or window frame about a hinge axis.
[0006] Such hinge assemblies and hinge components are known in various forms from the prior art. They serve to rotatably mount the door or window sash to a frame. Hinge assemblies typically comprise a sash-side hinge component and a frame-side hinge component. The frame-side hinge component typically includes a hinge part, also called a hinge bracket, which is rotatably mounted in a frame-side receptacle of the hinge assembly about the hinge axis. The hinge component, usually mounted on the sash side, generally comprises only a fastening element and a hinge component as a connecting element to the hinge pin located in the hinge axis. To enhance the aesthetic effect and to optimally utilize the available space, parts of the hinge assembly, in particular the frame-side receptacle and the hinge axis, can be arranged in a recess of the frame, usually the frame profile.In this context, the expert refers to concealed band arrangements.
[0007] Typically, the first and second hinge sections are firmly screwed to the sash or frame, at least with one mounting section. The hinge bracket of one hinge section is usually rotatable at its mounting point. JK / HAH 2503 PCT 2 February 6, 2026
[0008] The section is stored and connected to the other part of the hinge. Especially with concealed hinges, a compromise often has to be made between optimal aesthetics and ease of installation. For example, the components that engage in the frame recess sometimes prevent convenient installation of the system.
[0009] In particular, it has been shown that a relatively large amount of clearance is required to properly secure the hinge components and their respective fastening sections to the sash or frame, ensuring sufficient accessibility and enabling safe and relatively easy installation. Furthermore, fixing the hinge components with screws requires increased attention from the installer, especially to ensure the screws engage correctly in the corresponding frame or sash profile. Additionally, it is sometimes necessary to pre-drill holes in the sash or frame for the fastening screws. This also typically requires ample access.
[0010] The object of the present invention is therefore to provide a belt arrangement in which at least one of the above-mentioned disadvantages is improved and, in particular, the assembly and adjustment of the belt is made easier.
[0011] The invention solves the stated problem by means of a band arrangement with the features of the main claim. Advantageous embodiments and further developments of the invention are disclosed in the dependent claims, the description, and the figures.
[0012] The hinge assembly according to the invention comprises a first hinge part attachable to one of the sash and the frame, and a second hinge part attachable to the other of the sash and the frame. The first hinge part comprises a mounting part forming a housing section with a receiving area, and a first hinge part that can be arranged at least partially in the receiving area and pivoted about the hinge axis. The second hinge part comprises a fastening part for attachment to the sash or frame and a second hinge part. According to the invention, the first hinge part is fastened to the second hinge part by means of at least one hinge part fastening screw. This allows for a particularly effective JK / HAH 2503 PCT 3 February 6, 2026
[0013] and thus a comparatively high force transmission from the wing via the hinge parts into the frame, as well as improved manufacturing of the hinge, in that the two hinge parts can be pre-assembled and on-site first attached to the frame and then attached to the wing, whereby a particularly large amount of assembly space can be provided in the longitudinal extension of the fastening screws, so that the final assembly is improved overall.
[0014] The hinge components are formed primarily by those parts that together constitute the hinge bracket. This connection of the hinge components – which is particularly detachable – within the hinge bracket allows for excellent accessibility for mounting the two hinge components to the sash or frame, thus enabling a particularly convenient and secure installation.
[0015] Preferably, a separately formed mounting bracket is provided for attaching the first hinge part to the second hinge part, wherein the at least one hinge part mounting screw for attaching the first hinge part to the second hinge part extends through this mounting bracket. In particular, it can be provided that the second hinge part and the mounting bracket together enclose a cassette in which a coupling section of the first hinge part is located. This allows the second hinge part to be attached to the first hinge part in a particularly secure and easy-to-install manner. Furthermore, a particularly high force transmission between the first hinge part and the second hinge part is enabled.
[0016] Preferably, the mounting bracket has only holes for the hinge part mounting screw. This allows the mounting bracket to serve solely for force transmission between the hinge parts, thus enabling a particularly high force transmission between the first and second hinge parts.
[0017] Preferably, the first hinge part is arranged to overlap the second hinge part at least partially. This results in a particularly stable and secure JK / HAH 2503 PCT 4 6 February 2026
[0018] A connection between the two hinge parts is enabled in the area of the hinge components, allowing for a particularly high force transmission between the first and second hinge components. Furthermore, accessibility during installation, especially when attaching the hinge components to the sash or frame, is improved.
[0019] Preferably, the screw head of the hinge component fastening screw rests with its clamping or contact surface against the fastening web. This enables a direct and particularly high force transmission between the first hinge component and the second hinge component.
[0020] Particularly preferred is the arrangement of at least one hinge component fastening screw perpendicular to the hinge axis in its longitudinal extension. This enables a particularly high force transmission between the first hinge component and the second hinge component.
[0021] Preferably, a cassette, in particular a slotted cassette, or at least a side wall of a cassette, is provided between the first and second hinge parts, wherein a coupling section of one of the hinge parts can be inserted and fastened in the cassette. For assembly, one hinge part can thus be inserted into the cassette formed on the other hinge part. This allows the two hinge parts to be mounted in a particularly simple manner and fastened securely to each other. This enables a particularly high force transmission between the first and second hinge parts. In particular, it can be provided that the second hinge part and the fastening lug enclose the cassette.
[0022] Preferably, the cassette is arranged between the mounting bracket and the second hinge part, in particular such that the mounting bracket rests against the cassette on one outer side. This allows the hinge assembly to be particularly compact.
[0023] Preferably, the fastening part has a positive locking element and a locking screw, and the locking screw is designed to comply with JK / HAH 2503 PCT 5, February 6, 2026.
[0024] The form-fitting part can be brought into operative connection, with the locking screw being located adjacent to a longitudinal end of the cassette. This enables a particularly secure fastening of the second hinge part to the first of the sash and the frame.
[0025] Two hinge-part fastening screws are particularly preferred. These can extend through the aforementioned cassette. This ensures a particularly stable and secure connection between the two band sections in the hinge area.
[0026] According to a further embodiment, the first hinge part and the second hinge part can be moved relative to each other, and in particular adjusted, by means of a hinge part adjusting screw, in particular a setscrew. This allows adjustment of the hinge part directly at the hinge bracket, which is usually easily accessible from the outside.
[0027] The hinge adjustment screw is preferably arranged longitudinally perpendicular to the hinge axis and perpendicular to the longitudinal axis of the hinge mounting screw. This allows for particularly effective adjustment and a particularly secure fastening.
[0028] Preferably, the housing section is formed by at least four side walls of the mounting part. This provides additional stability to the first hinge section. Furthermore, it effectively prevents dirt from entering the interior of the profile. The housing section can, in particular, be manufactured as a single piece. This makes the hinge section especially space-saving and easy to install. In particular, the hinge section can also be inserted and fastened in small recesses of a frame or sash profile. Moreover, the housing can be manufactured very cost-effectively.
[0029] Preferably, the side walls are arranged at angles to each other. In particular, the side walls form a shell that is closed on four sides. This allows for particularly high stability in the first belt section. JK / HAH 2503 PCT 6 February 6, 2026
[0030] Preferably, in a mounted state of the hinge section on a wing or frame profile, a fifth side of the housing section is formed by a profile wall. This allows the first hinge section to be additionally supported by the profile, thus achieving particularly high stability in the first hinge section.
[0031] Preferably, a separate mounting plate is also provided, which can be inserted into and fastened in a groove formed on one side of the sash and the frame, and to which the fastening element can be attached by means of at least one screw. This allows the first hinge section to be positioned on the sash or frame independently of the groove size of the profile. The mounting plate can have a positive locking element with a protruding gripping section for engaging behind a corresponding, in particular undercut, first strip section formed on one side of the sash and the frame. This enables a particularly secure fastening of the mounting plate to one side of the sash and the frame.
[0032] Preferably, grooves or grooves are formed on the contact surface between the mounting plate and the mounting part, either on the mounting plate or on the mounting part itself. This allows for particularly convenient adjustment of the second strap section relative to the mounting plate.
[0033] In a further embodiment, the fastening element may include a positive-locking part and a locking screw for attachment to the sash or frame, wherein the locking screw can be brought into operative contact with the positive-locking part. The operative connection may be such that the positive-locking part and the locking screw act against each other, particularly to achieve a clamping effect. This allows the hinge component to be mounted to the sash and frame in a particularly simple manner, especially without requiring a particularly large amount of clearance for adequate accessibility.
[0034] The positive locking element and the locking screw together can, in particular, form a positive locking connection between the hinge part and one of the sash and the frame. Thus, the hinge part can be secured by means of the positive locking element, wel-JK / HAH 2503 PCT 7 February 6, 2026
[0035] The hinge part can form a first positive locking area, and the locking screw, which can form a second positive locking area, is positively locked to the sash or frame. The positive locking connection can be opened by turning and driving the locking screw relative to the hinge part. In particular, the second positive locking area can be formed in the area of, or by, the locking screw protruding from the side of the mounting part of the second hinge part facing the sash or frame, or it can be non-evident if the locking screw is screwed into the side of the mounting part facing the sash or frame and does not protrude. This allows the hinge part to be mounted to the sash and frame in a particularly simple manner.
[0036] To enable the hinge component and locking screw to be positioned precisely and as easily as possible on the sash or frame, particularly on a strip to be engaged behind it, the hinge component can have a raised section or projection on the outer surface that faces the aforementioned strip during installation and on which the locking screw can be unscrewed from a threaded hole to act as a positive locking element. The projection preferably extends completely around the opening of the threaded hole. Alternatively, the projection can be a locally formed raised section in the area of the threaded hole opening. The projection can be designed such that it, too, can engage at least partially behind the aforementioned strip of the sash or frame during installation. To simplify the engagement or pivoting of the projection behind the strip, a rounded edge can be formed on the side of the projection.The projection can therefore primarily serve as a guide element. Furthermore, the projection can be used to temporarily hold or fix the hinge component to the sash or frame. After the projection engages behind the strip, the locking screw can be used during assembly to create a positive fit and thus secure the hinge component to the sash or frame.
[0037] Preferably, the positive locking element and the locking screw are operatively connected in such a way that the fastening element to the sash or frame can be attached not only positively but also clamped. For this purpose, the hinge part can be unscrewed by means of the JK / HAH 2503 PCT 8 6 February 2026
[0038] The form-fit connection can also be achieved by clamping it to one side of the sash and the frame. In particular, the fastening element can be attached to the sash or frame solely by clamping. This can be done without screwing the locking screw into the sash or frame. This allows for both improved installation and a particularly stable and secure attachment of the hinge component to the sash or frame.
[0039] To further optimize the fastening, the form-fitting element can have a protruding gripping section for engaging a corresponding profile section on the sash or frame. This profile section can, for example, be an undercut first strip section. This allows the hinge component to be hooked behind the strip section of the sash or frame profile during installation and held, at least temporarily, by the profile. The locking screw can then secure the form-fitting element in a positive-locking connection.
[0040] Preferably, the form-fitting element between the gripping section and the hinge section has a groove-shaped recess into which the first strip section can engage. The recess next to the protruding gripping section allows for improved force transmission. In particular, the recess can be designed as a recess open towards the hinge section of the second hinge section or towards the first strip section. This allows the hinge section to be easily hooked behind the strip section of the sash or frame profile during installation and at least temporarily secured.
[0041] The groove-shaped recess can, in particular, have an insertion opening through which the first strip section can be inserted into the groove-shaped recess in an insertion direction. The insertion direction is advantageously oriented perpendicular to the hinge axis. This allows the form-fitting part with the gripping section to be hooked into or behind the strip section in a particularly simple manner. JK / HAH 2503 PCT 9 February 6, 2026
[0042] To absorb particularly high forces, the positive locking element preferably extends along the entire length of the hinge section in the direction of the hinge axis. This allows for a particularly large contact surface, enabling the hinge section to transfer especially high forces into the frame and thus making the hinge section suitable even for hinges of particularly heavy sashes.
[0043] In a further embodiment, the locking screw can be arranged on the hinge section in such a way that it can engage behind a second sash or frame section, which is located opposite the first sash section and is particularly undercut. The second sash section is typically formed on the same component, particularly the same profile, as the first sash section. The second sash section can be located opposite the first sash section and / or be a mirror image of it. Accordingly, the part of the locking screw forming the second positive locking area can also be located opposite the positive locking part forming the first positive locking area and / or be a mirror image of it in its function. The locking screw can thus be designed as a component of a positive locking connection between the hinge section and one of the sash and frame sections.In particular, the locking screw can thus be designed as a movable positive locking element. This enables a particularly stable and secure connection between the hinge component and the sash or frame. Furthermore, the locking screw allows for a particularly effective securing of the hinge component to the sash or frame.
[0044] Preferably, the locking screw is arranged on the hinge section such that at least one end of the locking screw can engage behind the second strip section. This means that the end of the locking screw can form the part of the positive locking connection between the hinge section and the sash or frame, also referred to above as the second positive locking area. The locking screw can protrude from or onto the fastening part of the hinge section and fix the hinge section to the sash or frame without being threaded into the sash or frame. The hinge section can be clamped in particular between the first strip section and the second strip section. This clamping is achieved, in particular, by the interaction of the gripping section of the positive locking element. JK / HAH 2503 PCT 10 February 6, 2026
[0045] and the locking screw. This allows for both improved assembly and a particularly stable and secure attachment of the hinge part to the wing or frame.
[0046] The locking screw can be arranged on the band section in such a way that the second band section can be advanced by means of the locking screw in the opposite direction to the insertion direction of the first strip section, and in particular with the gripping section behind the first strip section. Thus, by unscrewing the locking screw and subsequently supporting it against the second strip section, the gripping section can be moved completely behind the first strip section or until the first strip section is completely engaged in the groove-shaped recess, thereby achieving a particularly effective clamping of the band section.
[0047] For the locking screw to interact with the form-fitting element, a specific arrangement and orientation of the locking screw is required. Therefore, the locking screw and / or a threaded bore in the hinge section with which the locking screw engages can extend transversely through the hinge section, so that the locking screw head, which has a tool receptacle, faces a first side surface of the hinge section facing the hinge part, and the opposite end of the screw faces a second side surface of the hinge section facing away from the hinge part. This allows the locking screw to function on one side facing the sash or frame and to be operated from the other side facing away from the sash or frame.
[0048] It has been found that the locking screw is advantageously arranged at an angle to the first side surface, the second side surface, and / or the insertion direction along its longitudinal axis. An angle of inclination is understood to be, in particular, between 15° and 75°. This arrangement and alignment of the locking screw is particularly suitable for achieving a clamping effect while simultaneously ensuring good accessibility for operation.
[0049] Furthermore, it has been shown that it can be advantageous if the locking screw is arranged longitudinally perpendicular to the hinge axis. (See JK / HAH 2503 PCT 11, February 6, 2026)
[0050] particularly large forces are transmitted between the hinge part and the wing or frame.
[0051] Particularly preferably, the mounting part has a fastening section to which it can be attached to one side of the sash and the frame by means of fasteners. The fastening section can, for example, be arranged laterally adjacent to the housing section, in particular outside a recess or depression in the sash or frame profile, especially on an end face of the frame facing the sash, which is very easily accessible from the outside.
[0052] For improved adjustability of the hinge part, at least one elongated hole can be formed in the fastening section of the mounting part, through which a fastening means for fixing the mounting part to the sash or frame profile extends, so that the mounting part can be displaced relative to the fastening means, particularly in the longitudinal extent of the mounting part.
[0053] According to a further embodiment, the first hinge section may include at least one adjustment element that can be attached to one of the sash and the frame, particularly independently of the mounting part. This allows a large part of the hinge's adjustment mechanism to be located in a position that is easily accessible from the outside.
[0054] Preferably, the adjusting element includes means for repositioning the mounting part, in particular means that can effect repositioning in a direction parallel or perpendicular to the hinge axis. These means can, for example, include an adjusting screw. This allows for particularly convenient adjustment of the hinge.
[0055] Preferably, the means comprise at least one mounting part adjustment screw, which bears against the mounting part with an end face section, in particular at an end face of the mounting part. The mounting part adjustment screw can, for example, be used to adjust the entire mounting part relative to the JK / HAH 2503 PCT 12 February 6, 2026
[0056] The adjustment part can be repositioned. This allows for particularly convenient adjustment of the strap.
[0057] Preferably, at least one fastening element of the mounting part extends additionally through a recess in a fastening section of the adjusting part. This allows for particularly convenient adjustment of the band.
[0058] Furthermore, it can be provided that, for attaching the second hinge section to one of the sash and frame, the second hinge section, particularly in the attachment section, has a positive locking element with a gripping section for engaging behind a first strip section that corresponds to one of the sash and frame, and is in particular undercut. For this purpose, the positive locking element preferably extends along the entire length of the hinge section in the direction of the hinge axis. Preferably, the positive locking element has a groove-shaped recess between the gripping section and the hinge section, in particular a recess that is open towards and corresponds to the first strip section. Most preferably, the groove-shaped recess has an insertion opening through which the first strip section can be inserted into the groove-shaped recess in an insertion direction perpendicular to the hinge axis.According to a further development of this invention, the second hinge section has at least one locking screw for engaging behind a second strip section of the sash and frame, which is arranged on one of the sash and frame, particularly opposite the first strip section, and which is in particular undercut. The locking screw can be arranged on the second hinge section such that the second hinge section can be advanced by means of the locking screw in the direction opposite to the insertion direction of the first strip section, and in particular with its gripping section behind the first strip section. The locking screw can be designed as a component of a positive locking connection between the second hinge section and the sash and frame. In particular, the locking screw can be arranged on the second hinge section such that the locking screw can engage behind the second strip section at least with an end face.Preferably, the locking screw and / or a threaded bore with which the locking screw engages extends transversely through the second band part, so that the JK / HAH 2503 PCT 13 February 6, 2026.
[0059] The locking screw has a screw head with a tool receptacle facing the first side surface of the second hinge section, which is adjacent to the hinge section, and an opposite screw end facing the second side surface of the second hinge section, which is opposite the hinge section. The locking screw can be arranged longitudinally perpendicular to the hinge axis; preferably, the locking screw is arranged longitudinally at an angle to the first side surface, the second side surface, and / or the insertion direction. This allows for particularly convenient assembly and adjustment of the hinge assembly.
[0060] The first hinge part is particularly preferably curved and / or bifurcated. The first hinge part can, in particular, have a first leg section facing the hinge axis and a second leg section facing the second hinge part. The first leg section and the second leg section are preferably flat, i.e., not curved. A transition area can be provided between the first leg section and the second leg section, connecting the two legs at a corner, arc, or curve. The connection between the first leg section and the second leg section extends, in particular, over the entire width of the first hinge part.This arc-shaped design allows, in particular, the hinge adjustment screw, which can be provided on or in the second leg section, to be arranged at an angle to the second hinge part, which enables a particularly precise and effective adjustment of the horizontal and sealing pressure of the sash relative to the frame, especially without a noticeable lateral offset of the sash relative to the frame.
[0061] Preferably, an angle of between 20° and 90° is formed between the first leg section and the second leg section, more preferably between 45° and 80°, and particularly preferably between 50° and 75°. It has been shown that an angle of 50° to 75°, and in particular an angle of 70°, formed between the first leg section and the second leg section, enables optimal guidance and alignment of the hinge adjustment screw for adjusting the horizontal and sealing pressure of the sash relative to the frame. This allows for an opening angle of the JK / HAH 2503 PCT 14 February 6, 2026
[0062] The angle of the wing relative to the frame can be achieved between 105° and 108°, particularly without any collision of components.
[0063] Furthermore, it has been shown that it is advantageous if the first and second leg sections have essentially the same length. The length of the first leg section extends in the direction between the transition to the second leg section and the hinge axis. The length of the second leg section extends in the direction between the transition to the first leg section and the free end located at the coupling section. This allows for particularly effective force transmission through the first hinge section and enables a particularly advantageous pivoting of the sash relative to the frame.

[0073] Figure 9 - the band arrangement according to Fig. 8 in an assembled state; and
[0074] Figure 10 - a side view of the belt arrangement according to Fig. 8 in an assembled state.
[0075] The first embodiment of a hinge arrangement according to the invention, designated 101 in each of Figures 1 to 4, is designed as a concealed hinge arrangement for the rotatable attachment of a door or window sash 50 (not shown in these figures) to a door or window frame 40 (not shown in these figures) about a hinge axis S. The hinge arrangement 101 comprises a first hinge part 1, which can be attached to one of the sash 50 and the frame 40, and a second hinge part 2, which can be attached to the other of the sash 50 and the frame 40.
[0076] The first hinge section 1 comprises a mounting part 10 and a first hinge part 11 that pivots about the hinge axis S. The mounting part 10 and the first hinge part 11 are formed separately. Additionally, the first hinge section 1 comprises two adjustment parts 12a and 12b for adjustment purposes.
[0077] A hinge pin 8, defining the hinge axis S, is mounted on the mounting part 10. The mounting part 10 comprises a housing section 13 with a receiving area 14. The receiving area 14 includes, in particular, two opposing bores 14a, 14b in which the hinge pin 8 is mounted. The receiving bores 14a, 14b are arranged such that at least part of the first hinge part 11 can be located within the housing section 13.
[0078] The housing section 13 is formed in this case by four side walls 10a, 10b, 10c, 10d of the mounting part 10. The side walls 10a, 10b, 10c, 10d are in particular formed by three sections 10a, 10b, 10c of a long strip, arranged at an angle to each other in the direction of their longitudinal extent, and in particular folded. JK / HAH 2503 PCT 16 February 6, 2026
[0079] and formed by a fourth side wall lOd that laterally delimits this section. The side walls 10a, 10b, 10c, lOd thus form a kind of shell, which is closed on four sides. In a mounted state of the hinge section 1 on a sash or frame profile 40, 50, it is provided that a fifth side of the housing section 13 is formed by a wall of the sash or frame profile 40, 50. This results in particularly high stability of the mounting part 10. In this case, the mounting part 10 is thus designed as a long hinge with the additional side wall lOd.
[0080] For attachment to one of the sash 50 and the frame 40, the mounting part 10 has a mounting section 16a, 16b adjacent to the housing section 13 in the direction of its longitudinal extent, to which the mounting part 10 can be attached by means of fastening elements 17, 17', 17", 17"'. The fastening elements 17, 17', 17", 17"', designed as fastening screws, each extend through an elongated hole 18, 18', 18", 18"' arranged in the mounting section 16a, 16b. This allows the mounting part 10 to be displaced in its longitudinal extent relative to the fastening element 17, 17', 17", 17"' or to the sash 50 or frame 40 for the purpose of adjustment.
[0081] The two adjustment parts 12a, 12b serve for the vertical adjustment of the mounting part 10. For this purpose, the adjustment parts 12a, 12b can each be attached independently of the mounting part 10 in a mounting section 25 on one of the sash 50 and the frame 40. They are attached using the mounting screws 17, 17', 17", 17'", which are also used to attach the mounting part 10. The screws 17, 17', 17", 17'" extend through bores 24, 24', 24", 24"' provided in the adjustment parts 12a, 12b into one of the sash 50 and the frame 40, thus holding the adjustment part 12a, 12b in position even when only slightly screwed into the sash 50 or frame 40 – particularly during adjustment.
[0082] For adjusting the mounting part 10, means 19, 19' are provided for displacing the mounting part 10 relative to the adjustment part 12a, 12b, which is positioned and fixed on one of the sash 50 and the frame 40, in particular in a direction parallel or perpendicular to the hinge axis S. The means 19, 19' are arranged on the adjustment part 12a, 12b and are each specifically designed as a JK / HAH 2503 PCT 17 February 6, 2026
[0083] The mounting part adjustment screw 19, 19' is designed as a setscrew and has an end face section 39, 39' at an end facing the mounting part 10, which bears against the mounting part 10, in particular against an end face 38, 38' of the mounting part 10. Furthermore, the means 19, 19' comprise at least one locking screw 19", 19"' arranged on the adjustment part 12a, 12b.
[0084] The second hinge part 2 comprises a fastening part 20 for attachment to the sash 50 (not shown in Figures 1 to 4) or frame 40 (not shown in these figures), and a hinge part 21, which is hereinafter also referred to as the second hinge part. The fastening part 20 comprises a positive locking element 3 and a locking screw 4, which together serve to fasten the second hinge part 2 to the sash 50 or frame 40. For this purpose, the positive locking element 3 and the locking screw 4, 4' are operatively connected.
[0085] In a first and second embodiment of the invention, which are designated by reference numerals 100 and 101, the fastening part 20 and the second hinge part 21 are formed by a connected, in particular one-piece, component.
[0086] Alternatively, as shown in Figures 5 to 7 with the second embodiment of a hinge arrangement 102 according to the invention, the second hinge part 21 can be attached to a wing or frame by means of a separately formed mounting plate 60. In this case, the mounting part 20 is also formed integrally with the second hinge part 21, but comprises only a contact surface. The separate mounting plate 60 can be inserted into a groove formed on one of the wing 50 and the frame 40 and can be attached to the wing or frame (not shown in Figures 5 to 7) by means of screws 61, 61', and the mounting part 20 can be attached to this wing or frame by means of at least one screw 4", 4'".The mounting plate 60 can have, on a side facing the sash 50 or frame 40, the same contour and properties for mounting on a groove of the sash 50 or frame 40 as the mounting part 20 which is integrally connected with the second hinge part 21, insbe-JK / HAH 2503 PCT 18 6 February 2026.
[0087] rather a positive locking part 3 or alternatively a pure contact surface without positive locking.
[0088] On a side facing away from the sash 50 or frame 40, the mounting plate 60 can have a contact surface 62 for the second hinge part 21 to rest against. This contact surface 62 can have grooves or grooves on the mounting plate 60 and / or on the second hinge part 21. This makes it particularly easy to align the second hinge part 21 on the mounting plate 60.
[0089] The positive locking element 3 formed on the fastening part 20 or the fastening plate 60 comprises a projecting gripping section 31 and a groove-shaped recess 32. The gripping section 31 serves to engage behind a first strip part 41, which is formed correspondingly on one of the sash 50 and the frame 40, and in particular is undercut, as can be seen especially in Figure 10. The groove-shaped recess 32 formed between the gripping section 31 and the second hinge part 21 provides a particularly stable fastening option. The recess extends in the direction of the hinge axis S over the entire length L of the hinge part 2. This allows the first strip part 41 to additionally engage in this recess 32, so that the positive locking element 3 can be fixed particularly securely to the sash 50 and the frame 40. The recess 32 is open towards the first strip part 41 for this purpose.In particular, the groove-shaped recess 32 has an insertion opening 33 through which the first strip part 41 is inserted into the recess 32 in an insertion direction RI perpendicular to the hinge axis S.
[0090] It should be clear that the embodiment of the attachment of the second band part 2 to the wing 40 or frame 50 shown in Figures 8 to 10 with reference to a third embodiment of the band arrangement 100 according to the invention can also be provided in the same way in the first embodiment according to the invention according to Figures 1 to 4, wherein, for the sake of clarity, only the wing 40 or frame 50 is not shown in the latter Figures 1 to 4. JK / HAH 2503 PCT 19 February 6, 2026
[0091] As can be seen particularly in Figure 10, the locking screw 4, 4' serves both to advance the second band section 2 towards the positive-locking part 3, in particular to advance the gripping section 31 behind the first strip section 41, and to secure the second band section 2 to the wing 50 or frame 40 by clamping it against the positive-locking connection. For this purpose, the locking screw 4, 4' engages with a thread formed on the second band section 2. The locking screw 4, 4' engages exclusively with the thread of the second band section 2.Furthermore, the locking screw 4, 4' is arranged on the second hinge section 2 such that the locking screw 4, 4' can engage behind a second strip section 42 of the sash 50 or frame 40 with at least one end section 5, which may project laterally from the second hinge section 2, and can be supported in this area against the sash 50 or frame 40, in particular without being screwed into the sash 50 or frame 40. When turned further, the locking screw 4, 4' acts like a spindle to advance the second hinge section 2, but only under end-face contact with the sash 50 or frame 40.
[0092] The second strip section 42 is optimally arranged opposite the first strip section 41, in particular in a mirror image to the first strip section 41. By turning the locking screw 4, 4' while simultaneously pushing the screw 4, 4' out of the second strip section 2 in the direction away from the second strip section 2, the second strip section 2 can be advanced in the direction opposite to the insertion direction RI of the first strip section 41.
[0093] To enable the hinge section 2 to be positioned precisely on the frame 40 in the simplest possible manner, the hinge section 2—as shown in Figure 10—has a projection 29 on the outer surface 28 that faces the strip section 42 during assembly and on which the locking screw 4, 4' can be unscrewed from a threaded bore 6, 6'. The projection 29 can be designed such that it can engage at least partially behind the strip section 42 during assembly. This allows the hinge section 2 to be held at least temporarily on the frame 40, particularly until the locking screw 4 is turned to create a positive fit and thus secure the hinge section 2 to the frame 40. JK / HAH 2503 PCT 20 February 6, 2026
[0094] To enable effective feeding of the second hinge section 2, the locking screw 4, 4' or a threaded bore 6 with which the locking screw 4, 4' engages is arranged such that it extends transversely through the second hinge section 2 and a screw head 7 of the locking screw 4, 4', which has a tool receptacle, faces a first outer surface 27 of the second hinge section 2 facing the second hinge section 21, and an opposite screw end 5, 5' faces a second outer surface 28 of the second hinge section 2 facing away from the second hinge section 21. The longitudinal orientation of the locking screw 4, 4' is, in particular, inclined to the first outer surface 27, inclined to the second outer surface 28, and inclined to the insertion direction RI, where "incident" is understood to mean, in particular, an angle between 15° and 75°. In this case, the angle is approximately 45°.
[0095] The positive locking element 3 and the locking screw 4, 4' together form a positive locking connection 9 between the band part 2 and the frame 40, in particular an openable positive locking connection 9. Furthermore, the positive locking element 3 and the locking screw 4, 4' can be operatively connected in such a way that the fastening of the fastening part 20 to the frame 40 is not only positively locked, but also clamped under force. Thus, as can be seen particularly in Figure 10, the positive locking connection shown there can be formed by unscrewing the locking screw 4, 4' with the end face 5, 5' and clamped by further turning under force. By screwing the locking screw 4, 4' in or out of the threaded bore 6, 6' formed on the second band part 2, the positive locking element formed under the end face 5, 5' of the locking screw 4, 4' can be withdrawn and the positive locking can thus be completely released.The second hinge part can thus be attached to the wing 50 or frame 40 in a particularly simple manner. The locking screw 4, 4' is located adjacent to a longitudinal end of a cassette 22, into which at least one coupling section 15 of the first hinge part 11 is inserted and fastened.
[0096] For mounting and adjusting the wing 50 to the frame 40, the first hinge part 11 of the first hinge part 1 is attached to the second hinge part 21 of the JK / HAH 2503 PCT 21 February 6, 2026
[0097] The second hinge part 2 is detachably and adjustably attached. The first hinge part 11 is arranged to overlap the second hinge part 21 at least partially. In particular, a coupling section 15 of the first hinge part 11 is inserted into the slot-shaped cassette 22. The cassette 22, in turn, is attached to the second hinge part 21.
[0098] The first hinge part 11 is attached to the second hinge part 21, and the cassette 22 is attached to the second hinge part 21, by means of two hinge part fastening screws 23a, 23b, which are arranged longitudinally perpendicular to the hinge axis S. The hinge part fastening screws 23a, 23b pass through a separately formed fastening rib 21a, which is provided to increase strength.
[0099] The mounting bracket 21a rests against the outside of the cassette 22 and, together with the second hinge part 21, encloses the cassette 22, in which the first hinge part 11 is housed, and the second hinge part 21. The mounting bracket 21a is designed as a flat plate and has only bores for the hinge part mounting screws 23a, 23b. As a result, each hinge part mounting screw 23a, 23b, which engages with a thread in the cassette 22, rests with its screw head against the mounting bracket 21a and pre-tensions the mounting bracket 21a in the direction of the cassette 22.
[0100] For adjustment, the first hinge part 11 and the second hinge part 21 can be moved relative to each other by means of a hinge part adjustment screw 26 designed as a setscrew. The adjustment is provided in particular in the direction perpendicular to the hinge axis S and perpendicular to the longitudinal extent of the hinge part fastening screw 23. This allows for both simple assembly and particularly easy adjustment of the hinge.
[0101] As can be seen particularly from Figures 1, 4, 6, 7, 8 and 10, the first hinge part 11 is designed as a two-legged hinge with a first leg section facing the hinge axis S (in Figure 5 in the area of the arrowhead of reference numeral 11) and a second leg section facing the second hinge part 2 (in Figure 5 in the area of the arrowhead of reference numeral 15). Between the first leg section and the second leg section is JK / HAH 2503 PCT 22 February 6, 2026
[0102] A straight line, an arc, or a curve is formed. The angle between the first leg section and the second leg section is approximately 50 to 80°, particularly 70°. This allows for optimal guidance and alignment of the hinge section adjusting screw 26 for adjusting the horizontal and sealing pressure of the sash 50 relative to the frame 40. It is also evident that the first leg section, with respect to the direction between the transition to the second leg section and the hinge axis, and the second leg section, with respect to the direction between the transition to the first leg section and the free end located at the coupling section, have essentially the same length.
[0103] The third embodiment of a hinge arrangement according to the invention, designated by the letter 100 in each of Figures 8 to 10, is designed as a concealed hinge arrangement for the rotatable attachment of a door or window sash 50 to a door or window frame 40 about a hinge axis S. The hinge arrangement 1 comprises a first hinge part 1 that can be attached to one of the sash 50 and the frame 40, and a second hinge part 2 that can be attached to the other of the sash 50 and the frame 40. The second hinge part 2 corresponds to the further subject matter of the invention.
[0104] The first hinge section 1 comprises a mounting part 10 and a first hinge part 11 that pivots about the hinge axis S. The mounting part 10 and the first hinge part 11 are designed separately. Additionally, the first hinge section includes two adjustment parts 12a and 12b for adjustment purposes.
[0105] A hinge pin 8, defining the hinge axis S, is mounted on the mounting part 10. The mounting part 10 comprises a housing section 13 with a receiving area 14. The receiving area 14 includes, in particular, two opposing bores in which the hinge pin 8 is mounted. The receiving bores 14 are arranged such that at least a portion of the first hinge part 11 is located within the housing section 13.
[0106] The housing section 13 is formed in this case by at least three side walls 10a, 10b, 10c of the mounting part 10. The side walls 10a, 10b, 10c are in particular connected by three angles to each other in the direction of their longitudinal extent. JK / HAH 2503 PCT 23 February 6, 2026
[0107] The assembly is formed by arranged, in particular folded, sections of a long strip. Specifically, the entire assembly part 10 is designed as a long strip. To form the housing section 13, the long strip has at least two longitudinal sections formed at an angle to each other, which form the side walls 10a, 10b, 10c.
[0108] The second hinge part 2 comprises a fastening part 20 for attachment to one of the sash 50 and the frame 40, and a second hinge part 21. The fastening part 20 and the second hinge part 21 are formed by a single, in particular one-piece, component. The fastening part 20 comprises a positive locking element 3 and a locking screw 4, which together serve to fasten the second hinge part 2 to the sash 50 or frame 40. For this purpose, the positive locking element 3 and the locking screw 4, 4' are operatively connected.
[0109] The form-fitting part 3 comprises a projecting gripping section 31 and a groove-shaped recess 32. The gripping section 31 serves to engage behind a first strip part 41, which is formed correspondingly on one of the sash 50 and the frame 40, and in particular is undercut, as shown in Figure 10. The groove-shaped recess 32 formed between the gripping section 31 and the hinge part 21 provides a particularly stable fastening option. The recess extends in the direction of the hinge axis S over the entire length L of the hinge part 2. This allows the first strip part 41 to additionally engage in this recess 32, so that the form-fitting part 3 can be particularly securely fixed to the sash 50 and the frame 40. The recess 32 is open towards the first strip part 41 for this purpose.In particular, the groove-shaped recess 32 has an insertion opening 33 through which the first strip part 41 is inserted into the recess 32 in an insertion direction RI perpendicular to the hinge axis S.
[0110] The locking screw 4, 4' serves both to advance the second hinge section 2 towards the form-fitting part 3, in particular to advance the gripping section 31 behind the first strip part 41, and to secure the second hinge section 2 to the wing 50 or frame 40 by clamping it against the form-JK / HAH 2503 PCT 24 February 6, 2026
[0111] Final connection. For this purpose, the locking screw 4, 4' engages with a thread formed on the second hinge section 2. The locking screw 4, 4' engages exclusively with the thread of the second hinge section 2. Furthermore, the locking screw 4, 4' is arranged on the second hinge section 2 such that the locking screw 4, 4' can engage behind a second strip section 42 of the sash 50 or frame 40 with at least one end section 5, which may project laterally from the second hinge section 2, and can be supported in this area against the sash 50 or frame 40, in particular without being screwed into the sash 50 or frame 40. When turned further, the locking screw 4, 4' acts like a spindle to advance the second hinge section 2, but only under end-face contact with the sash 50 or frame 40.
[0112] The second strip section 42 is optimally arranged opposite the first strip section 41, in particular in a mirror image to the first strip section 41. By turning the locking screw 4, 4' while simultaneously pushing the screw 4, 4' out of the second strip section 2 in the direction away from the second strip section 2, the second strip section 2 can be advanced in the direction opposite to the insertion direction RI of the first strip section 41.
[0113] To enable the hinge section 2 to be positioned precisely on the frame 40 in the simplest possible manner, the hinge section 2 – as shown in Figure 10 – has a projection 29 on the outer surface 28 which, during assembly, faces the strip section 42 and on which the locking screw 4, 4' can be unscrewed from a threaded bore 6, 6'. The projection 29 can be designed, in particular, such that it can engage at least partially behind the strip section 42 during assembly. This allows the hinge section 2 to be held on the frame 40, at least temporarily, especially until the locking screw 4 is turned to create a positive fit and thus secure the hinge section 2 to the frame 40.
[0114] To enable effective feeding of the second band section 2, the locking screw 4, 4' or a threaded bore 6 with which the locking screw 4, 4' engages is arranged such that it extends transversely through the second band section 2 and has a tool holder. JK / HAH 2503 PCT 25 February 6, 2026
[0115] The head 7 of the locking screw 4, 4' faces a first outer surface 27 of the second hinge part 2, which faces the second hinge part 21, and an opposite screw end 5, 5' faces a second outer surface 28 of the second hinge part 2, which faces away from the second hinge part 21. The longitudinal orientation of the locking screw 4, 4' is, in particular, oblique to the first outer surface 27, oblique to the second outer surface 28, and oblique to the insertion direction RI, where "oblique" is understood to mean, in particular, an angle between 15° and 75°. In this case, the angle is approximately 45°.
[0116] The positive locking element 3 and the locking screw 4, 4' together form a positive locking connection 9 between the band part 2 and the frame 40, in particular an openable positive locking connection 9. Furthermore, the positive locking element 3 and the locking screw 4, 4' can be operatively connected in such a way that the fastening of the fastening part 20 to the frame 40 is not only positively locked, but also clamped under force. Thus, as can be seen particularly in Figure 10, the positive locking connection shown there can be formed by unscrewing the locking screw 4, 4' with the end face 5, 5' and clamped by further turning under force. By screwing the locking screw 4, 4' in or out of the threaded bore 6, 6' formed on the second band part 2, the positive locking element formed under the end face 5, 5' of the locking screw 4, 4' can be withdrawn and the positive locking can thus be completely released.This makes it particularly easy to attach the second part of the strap to the wing 50 or frame 40.
[0117] For mounting and adjusting the sash 50 on the frame 40, the first hinge part 11 of the first hinge section 1 is detachably and adjustably attached to the second hinge part 21 of the second hinge section 2. The first hinge part 11 and the second hinge part 21 are arranged to overlap at least partially. In particular, a slot-shaped cassette 22 is formed on the second hinge part 21, into which at least one coupling section 15 of the first hinge part 11 is inserted and secured. The first hinge part 11 is attached to the second hinge part 21 by means of two hinge part fastening screws 23a, 23b, which extend longitudinally perpendicular to the frame.
[0118] The hinge axis S is arranged. For adjustment, the first hinge part 11 and the second hinge part 21 can be moved relative to each other by means of a hinge part adjustment screw 26 designed as a setscrew. The adjustment is provided in particular in the direction perpendicular to the hinge axis S and perpendicular to the longitudinal extent of the hinge part fastening screw 23. This allows for both simple assembly and particularly easy adjustment of the hinge.
[0119] It should be clear that the scope of protection of the present invention is not limited to the embodiment shown. In particular, the design of the belt assembly and the belt section can be modified without altering the core of the invention. JK / HAH 2503 PCT 27 February 6, 2026
