[0004] Band flaps of a band for hinged connection of a wing profile with a frame profile and such a band

[0005] The invention relates to a hinge leaf of a hinge, in particular designed as a roller hinge, for connecting a sash profile to a frame profile in a hinge-like manner about a hinge axis, to a hinge part, to a mounting part that can be attached to one of the sash profiles and the frame profile by means of at least one fastening screw, and to a locking element. The invention further relates to a hinge with such a hinge leaf. The invention also relates to a hinge-side locking device with such a hinge leaf.

[0006] Such hinge flaps and corresponding hinges are well known in numerous designs. It should be clear that a hinge consists of at least two hinge flaps and a hinge pin arranged in the hinge axis, connecting the at least two hinge flaps to each other.

[0007] For optical or aesthetic reasons, attempts are regularly made to make the hinge plates, especially the visible hinge part, as small and inconspicuous as possible. At the same time, however, it is regularly necessary that the hinge part can be adjusted relative to the mounting part permanently attached to a profile. This, however, requires, for example, a certain amount of material as well as a certain amount of space for adjusting screws, which in turn makes such hinge plates somewhat larger. HAH 2410 PCT 2 January 13, 2026

[0008] and become more massive. Consequently, designers of such band flaps often have to find a compromise between the desired aesthetics and the structure required for the technology.

[0009] In the case of particularly heavy wings and / or particularly high loads, the construction of such ligament flaps can often only be achieved at the expense of the desired aesthetics in order to guarantee a permanently safe function.

[0010] In this context, the tape's resistance to tampering or destruction attempts must also be considered. For example, more robustly constructed tapes may exhibit greater resistance than more delicately constructed ones.

[0011] The object of the present invention is therefore to provide a band flap, a band with such a band flap and a band side securing device which improves at least one of the above-mentioned disadvantages and in particular enables a permanently secure and stable connection to hollow profiles.

[0012] The invention solves the problem by means of a band flap with the features of the main claim, by means of a band with the features of claim 14, and by means of a band side securing with the features of claim 15. Advantageous embodiments and further developments of the invention are disclosed in the dependent claims, the description, and the figures.

[0013] According to the invention, the locking element has a first contact surface and at least one countersunk pin projecting from the first contact surface – in particular substantially perpendicularly – and in a mounted state of the hinge on a sash or frame profile, that is, in a state in which the hinge part, in particular the hinge flap, and the locking element are arranged and fixed to one of the sash and frame profiles, the fastening screw for attaching the mounting part or, alternatively, a pin arranged on the mounting part extends through the countersunk pin of the locking element. The engagement of the mounting part with the locking element can thus be achieved by the at least HAH 2410 PCT 3 January 13, 2026

[0014] A fastening screw and / or at least one pin are used for fastening. For the sake of clarity, the following details, which are only mentioned in relation to the fastening screw, can equally apply to the aforementioned pins.

[0015] The locking element preferably has two countersunk pins projecting from the first contact surface, each of which is pierced by a fastening screw in the assembled state. This allows the mounting part to be permanently fixed in a predefined position on one of the sash profiles and the frame profile by means of the connection between the at least one fastening screw and the countersunk pin of the locking element, particularly also in a direction perpendicular to the first contact surface. This enables a permanently secure and particularly stable connection of the mounting profile to a hollow profile. Consequently, the force transmission from a sash via the hinge to the frame can be carried out in a particularly advantageous manner.In particular, the interaction of the fastening screws with the locking element and the resulting significantly larger contact and force transmission area with the sash or frame profile compared to conventional hinges allows for the transmission of considerably greater forces. This also provides enhanced protection for the hollow profile, which can be deformed during force transmission with conventional, small contact surfaces and / or thin-walled profiles. Furthermore, by relocating the aforementioned contact surfaces to the interior or intermediate areas of the profile, which are not always visible from the outside, it is possible to design the external, visible components of the hinge to be significantly smaller and thus more aesthetically pleasing.

[0016] The expression "one of the wing profile and the frame profile" refers specifically to one and the same profile, which can be either the wing profile or the frame profile. "The other of the wing profile and the frame profile" is accordingly also the same profile, but always the other of the two. HAH 2410 PCT 4 January 13, 2026

[0017] The countersunk pin, in its assembled state, can extend through at least part of one of the wing profiles and the frame profile, in particular through a projection of one of the profiles. The connection of the at least one fastening screw to the at least one countersunk pin of the locking element can, for example, be located in the end face of the respective countersunk pin.

[0018] The locking element is preferably designed separately. This allows the locking element to be mounted on the profile independently of the rest of the hinge. In particular, the locking element can be attached to one of the sash profiles and the frame profile, especially by means of at least one locking element fastening screw, also referred to here as a fixing screw. The locking element can rest against one of the sash profiles and the frame profiles with its first contact surface, which is preferably located on a large surface area of ​​the locking element. The at least one countersunk pin can preferably extend into the profile of the sash or frame.

[0019] In principle, the countersunk pin can be formed separately and fixed to the locking element. Preferably, the countersunk pin is formed on the locking element and forms a single component with it. The locking element and the countersunk pin can, in particular, be formed in one piece. This enables a particularly stable connection between the locking element and the profile – as well as the mounting part – especially for use with particularly heavy door leaves. Preferably, the countersunk pin extends substantially perpendicular to the first contact surface in its longitudinal direction. Most preferably, the countersunk pin extends parallel and perpendicular to the hinge axis in its longitudinal direction.

[0020] The countersunk pin can have a fit that corresponds to a recess formed in one of the wing profiles and the frame profile, for example, a cylindrical shape corresponding to a bore. The shape of the countersunk pin is irrelevant for the present invention. For example, the countersunk pin can be designed as a cylinder or a rod. Alternatively, the HAH 2410 PCT 5 January 13, 2026

[0021] The countersunk pin can also have a polygonal cross-section, for example, a square or hexagonal shape. Preferably, the countersunk pin has a length extending away from the first bearing surface that is greater than a width of the countersunk pin defined perpendicular to that length. Particularly preferably, the countersunk pin has a length that is approximately twice its width.

[0022] The locking element can have a second contact surface oriented essentially perpendicular to the first contact surface, wherein the locking element is preferably attachable to the second contact surface by means of at least one fixing screw to one of the wing profiles and the frame profile. The first contact surface can be oriented essentially parallel to the longitudinal extent of the fixing screw, and the countersunk pin can extend essentially perpendicular to the longitudinal extent of the fixing screw. This arrangement and orientation enables a particularly stable fixation of the locking element to the hollow profile.

[0023] Preferably, in the assembled state, the fixing screws extend essentially perpendicular to the longitudinal extent of the at least one countersunk pin. This arrangement and orientation enables a particularly stable fixing of the locking element to the hollow profile.

[0024] Preferably, the fastening screw passes through a recess formed in the countersunk pin, such as a bore. Particularly preferably, the countersunk pin has an elongated slot through which the fastening screw extends in the assembled state. The fastening screw can only pass through the elongated slot. In this embodiment, the fastening screw can be freely movable relative to the countersunk pin, at least in the axial (and rotational) direction. In a preferred embodiment, the fastening screw engages with the countersunk pin via a thread. For this purpose, a protrusion can be provided within the elongated slot, particularly at at least one location – preferably at two locations – with which the fastening screw engages a thread in the countersunk pin. HAH 2410 PCT 6 January 13, 2026

[0025] In a particularly preferred embodiment, the locking element has a front surface – oriented essentially perpendicular to the first contact surface – and at least one locking pin projecting from the front surface – preferably essentially perpendicularly. Such a locking pin serves to fix the sash in the frame when closed, preventing tampering attempts. For this purpose, the locking pin preferably engages in a corresponding recess provided in the frame when the sash is closed. This significantly limits the sash's freedom of movement relative to the frame. In particular, the sash cannot be pulled or pushed out of the frame in the direction perpendicular to the closing surface, as is the case with a door leaf.The arrangement of such a locking pin on a locking element, which is connected via at least one countersunk pin to at least one fastening screw of the mounting part of the strap flap, is therefore particularly advantageous. This allows very high manipulation forces to be transferred from the locking pin, via the locking element, into the frame.

[0026] In principle, the safety pin can be attached to the locking element in any way. In particular, the safety pin can be screwed, riveted, or welded to the locking element. In a special embodiment, the locking element has a threaded bore with which the safety pin engages via a threaded section. The safety pin can, in particular, have a section designed as a screw element. For this purpose, the safety pin can be designed as an elongated component with a pin, in particular a conical shape, on one axial section, especially half of the section, and with a threaded section over the other axial section. The safety pin can thus be inserted into the threaded bore provided in the locking element and fixed in place like a screw.This makes it possible to easily manufacture and offer different versions of such a door hinge. Furthermore, the locking pin can be quickly and easily replaced and / or added later. HAH 2410 PCT 7 January 13, 2026.

[0027] In a preferred embodiment, when a sash is closed, the locking element engages not only in a corresponding recess provided in the frame, but also in a recess of a counter-element attached to the frame. In particular, it is preferred that, in the assembled state, the locking element is attached to one of the sash profiles and the frame profile, and a counter-element with a receiving opening is attached to the other of the sash profiles and the frame profile such that, when the sash is closed, the locking pin engages through the receiving opening. Furthermore, it is preferred that, when the sash is opened or closed, the locking pin is moved in and out of the receiving opening without contact. This allows for particularly simple adjustment of the receiving opening's position relative to the locking pin, especially by sliding and adjusting the counter-element on the other side of the sash and frame profile.This allows for a particularly precise and exact interlocking of the locking pin with the receiving opening, and thus also a particularly effective locking mechanism.

[0028] The hinge component and the mounting component can, in principle, be a single, in particular one-piece, component. Preferably, the hinge component and the mounting component are designed as two separate components that can be attached to one another. Particularly preferably, the hinge component is movable relative to the mounting component in at least one adjustment direction. This allows for precise positioning of the sash relative to the frame.

[0029] Preferably, the mounting part has a first mounting surface for contact with one of the sash profiles and the frame profile, and at least one second mounting surface oriented substantially perpendicular to the first mounting surface for contact with the hinge part. This arrangement and orientation enables particularly suitable force transmission at the mounting part.

[0030] Furthermore, in the assembled state, the first mounting surface of the mounting part can preferably be oriented substantially perpendicular to the first mounting surface of the locking element. The first mounting surface can also be substantially parallel to the second mounting surface of the HAH 2410 PCT 8 13 January 2026

[0031] The locking element must be aligned. This also improves the force flow and thus the force transmission, especially in the relevant section of the hollow profile.

[0032] Particularly preferably, the mounting part and the locking element are arranged in the assembled state such that they are not in direct contact with each other. In particular, the mounting part and the locking element can be arranged without contact with each other in the assembled state. In particular, in the assembled state, the mounting part is connected to the locking element exclusively via the fastening screw.

[0033] Preferably, in the assembled state, the mounting part is arranged on a front wall of a profile projection and the locking element is arranged on a side wall of the profile projection that is oriented substantially perpendicular to the front wall, with the countersunk pin extending through the profile projection. This arrangement and orientation enables particularly suitable force transmission to the hollow profile, locking element, and mounting part.

[0034] Furthermore, the invention is solved by a band with a band flap having the features according to at least one of the aforementioned embodiments.

[0035] Furthermore, the invention is solved by a tape side securing device with a tape flap having the features according to at least one of the aforementioned embodiments.

[0036] Furthermore, the invention is solved by a locking element for sash profiles pivotably connected to a frame profile, such as doors, windows, and the like. The locking element is provided that it has a front surface and at least one locking pin projecting from the front surface and forming a positive-locking connection with a counter-element when the sash is closed. The locking element also has a first contact surface and at least one countersunk pin projecting from the first contact surface, the countersunk pin having a recess through which, in a mounted state, a HAH 2410 PCT 9 13 January 2026

[0037] A fastening screw, in particular one extending to a hinged flap of a hinge for connecting a sash profile to a frame profile via a hinge axis, is attached to a fastening screw that secures the sash profile and the frame profile. Preferably, the locking element has a threaded bore with which the safety pin engages with a threaded section.

[0038] An embodiment of the invention is explained in more detail below with reference to the figures. The same reference numerals denote the same components. The figures schematically show:

[0046] Figure 1 shows a first embodiment of a hinge leaf according to the invention of a hinge 100, which is shown here only in part. Further parts of the hinge 100, not shown in Figure 1, include in particular a second hinge leaf, which is attached to the other of the sash 8 and the frame 9. Also included in the hinge 100 is a hinge bolt, not shown in Figure 1, which connects the hinge leaf 1 shown here and the second hinge leaf, which extends along the hinge axis S. In this figure, the hinge leaf 1 is shown on the sash profile 8. Alternatively, the hinge leaf 1 can, of course, also be mounted on a frame profile 9, which is not shown here.

[0047] The wing profile 8 is designed as a hollow profile body and has a projection 10 extending towards the frame 9 at its end face. The projection 10 is formed by two projecting side walls and a first front wall 11 connecting the side walls. One of the side walls is designated by reference numeral 12. Adjacent to the projection 10, the profile 8 has a second front wall 13, which is essentially parallel to the first front wall 11. The second front wall 13 is formed on a main body of the profile 8, and not by the projection 10. In the closed state of the wing, the second front wall 13 is located internally between the wing and the frame and is therefore not visible from the outside. The projection 10 extends from this second front wall 13 of the profile 8, particularly towards the frame 9 (not shown).The band flap 1 is mounted on this projection 10, in particular on the first front wall 11 arranged at the front.

[0048] The hinge flap 1 serves to connect the sash profile 8 to the frame profile 9 by means of a hinge pivot about a hinge axis S. In the embodiment shown here, the hinge flap 1 comprises, among other things, a hinge part 7 and a separately formed mounting part 3. The hinge flap can, in principle, consist of only one part, or it can have more than two parts, as in the present case with the mounting part 3 and hinge part 7. In addition, a locking element 4 is provided according to the invention. HAH 2410 PCT 11 January 13, 2026

[0049] The hinge part 7 has a hinge sleeve surrounding the hinge pin (not shown) and can be displaced relative to the mounting part 3 in at least one adjustment direction and fastened to the mounting part 3 via mounting screws 3.5, 3.6 in a manner known per se. An additional adjusting screw 3.9 is provided to allow the hinge part 7 to be adjusted relative to the mounting part 3 in at least one direction.

[0050] The mounting part 3 has a first contact surface 3.1, also called the first mounting contact surface, which, in the assembled state 300, rests against the profile 8, in particular against the first front wall 11 of the profile projection 10. For receiving the hinge part 7, the mounting part 3 has a second contact surface 3.2, also called the second mounting contact surface. In the assembled state 300, the hinge part 7 rests with one flat side against the second contact surface 3.2. The first contact surface 3.1 is oriented essentially perpendicular to the second contact surface 3.2.

[0051] For attachment to the profile 8, the mounting part 3 has bores oriented perpendicular to the first mounting surface 3.1, through which fastening screws 3.3, 3.4 extend. Adjacent to the bores and fastening screws 3.3, 3.4, two dowel pins 3.6, 3.7 are also provided, which, in the assembled state 300, also extend from the mounting part 3 into the profile 8. The dowel pins 3.6, 3.7 serve to increase the stability of the connection between the mounting part 3 and the profile 8.

[0052] The locking element 4 according to the invention is formed separately and, in the assembled state 300, is arranged on the inner second front wall 13 of the profile 8. As already mentioned, the second front wall 13 cannot be seen from the outside when the sash 8 is closed in the frame 9. The locking element 4 mounted on the second front wall 13 is therefore also not visible from the outside in this state.

[0053] The locking element 4 has a main body 4.7 with a first contact surface 4.1 and a connection to the first contact surface 4.1 essentially HAH 2410 PCT 12 13 January 2026

[0054] The locking element 4 has a vertically oriented second contact surface 4.2. In addition to the main body 4.7, the locking element 4 has two countersunk pins 4.3, 4.4 projecting from the first contact surface 4.1. The countersunk pins 4.3, 4.4 are integrally connected to the main body 4.7. Alternatively, the countersunk pins 4.3, 4.4 can be formed separately and attached to the main body 4.7. This attachment can be achieved, for example, by screws, rivets, or another method such as cold forming, e.g., a wobble forming process. Furthermore, the locking element 4 has two bores 4.11, 4.12 on the second contact surface 4.2, through which two fixing screws 4.5, 4.6 extend for attaching the locking element 4 to the profile 8.

[0055] The locking element 4 is arranged on the profile 8 such that, in the assembled state 300, its first contact surface 4.1 rests against a side wall 12 of the projection 10 of the profile 8, and its second contact surface 4.2 rests against the second front wall 13 of the profile 8. The second contact surface 4.2 is, in particular, the main contact surface with which the locking element 4 rests against the profile 8, and in whose area the fixing screws 4.5, 4.6 secure the locking element 4 to the profile 8.

[0056] The countersunk pins 4.3, 4.4 projecting from the first contact surface 4.1 are cylindrical in shape, each corresponding precisely to one of the recesses formed in the projection 10. The countersunk pins 4.3, 4.4 may, in particular, have a slightly smaller diameter than the respective recess. Of course, it is possible for the countersunk pins 4.3, 4.4 to have different diameters, and for the corresponding recesses to have different diameters.

[0057] The countersunk pins 4.3, 4.4 have a diameter that is essentially equal to the thickness of the locking element 4. Furthermore, the countersunk pins 4.3, 4.4 have a length that is essentially twice the thickness of the locking element 4. In the assembled state 300, the countersunk pins 4.3, 4.4 extend through at least a portion of the profile HAH 2410 PCT 13 13 January 2026

[0058] 8, in particular by the profile projection 10, as can be seen in particular in Figure 3.

[0059] Each countersunk pin 4.3, 4.4 has a slotted recess 4.13, 4.14. This recess 4.13, 4.14 extends through the countersunk pin 4.3, 4.4 in a direction parallel to the bores 4.11, 4.12. In the assembled state 300, the fastening screws 3.3, 3.4, provided for securing the mounting part 3, extend through the slotted holes 4.13, 4.14 of the locking element 4. Alternatively, the dowel pins 3.6, 3.7 of the mounting part 3 can also extend through the slotted holes 4.13, 4.14. This creates a connection between the mounting part 3 and the locking element 4 within the profile 8, in particular within the projection 10, so that the mounting part 3 can be fixed to the profile 8 in a particularly space-saving and particularly stable manner.

[0060] On the second mounting surface 4.2, bores 4.11 and 4.12 are provided for the fixing screws 4.5 and 4.6, by means of which the locking element 4 can be fastened to the profile 8. The fixing screws 4.5 and 4.6 extend, in particular, perpendicular to the longitudinal extent of the countersunk pins 4.3 and 4.4, so that this arrangement enables a particularly stable fastening of the locking element 4 to the profile 8. In particular, this allows for a particularly secure and stable fastening as well as a particularly advantageous force transmission, especially via a particularly large contact area, between the sash profile 8 and the frame profile 9.

[0061] The following describes the assembly of the band flap 1. First, the locking element 4 is placed against the second front wall 13 and moved so that the countersunk pins 4.3, 4.4 are inserted into the corresponding recesses in the projection 10 until the contact surface 4.1 comes into contact with the side wall 12. In a further step, the fixing screws 4.5, 4.6 can be used to secure the locking element 4 to the profile 8. In a subsequent step, the mounting part 3 can be placed against the first front wall 11, and the fastening screws 3.3, 3.4 can be inserted through the holes provided in the mounting part 3 into the projection 10HAH 2410 PCT 14 13 January 2026

[0062] and are guided through the elongated holes 4.13 and 4.14 and screwed into the profile 8. In a further step, the hinge part 2 can be mounted, adjusted, and fixed to the mounting part 3.

[0063] Figures 2a and 2b show a particular embodiment of the strap, in particular the strap flap, and especially the locking element 4, wherein the strap 200 or strap flap 2 shown here differs from the strap 100 or strap flap 1 shown in Figure 1 only in that a locking pin 14 is additionally provided on the locking element 4. The strap 200 or strap flap 2 is also mounted in the same manner as described above.

[0064] The locking pin 14, also simply called pin, serves to additionally secure the sash 8 to the frame 9, particularly against attempts at manipulation and / or break-in. For this purpose, the locking pin 14 forms a projection attached to the profile, which protrudes from one of the pivotally connected profiles (sash or frame, in this case the sash 8) and has a shape that engages with a recess or a counter element 5 in the other pivotally connected profile (sash or frame, in this case the frame 9) when the sash is closed. The shape, size, and position of the pin 14, in conjunction with the shape, size, and position of the recess or counter element 5, are designed such that the pin 14 initially has a certain amount of play when it begins to penetrate the recess or counter element 5. Optionally, this play can decrease as the pin 14 continues to penetrate the recess or counter element 5.The counter element 5 is reduced to such an extent that the form – at the latest when the wing 8 is completely closed – is entirely located in the recess or the counter element 5, or is completely surrounded by it. The mandrel 14 can bear against the recess or the counter element 5 on at least one side.

[0065] The locking pin 14 has a pin section 14.1 and a threaded section 14.2, as can be seen in particular in the separate illustration of the pin 14 in Figure 4. This allows the locking pin 14 with the threaded section to be inserted into the additionally provided HAH 2410 PCT 15 13 January 2026 on the locking element 4.

[0066] The threaded bore 4.8 is screwed in. For this purpose, the locking pin 14 has a tool receptacle 14.3 at its free end face, for example a hexagon socket.

[0067] The counter element 5 shown in Figure 5 can, for example, be formed by a plate 5.1 which has a round recess or receiving opening 5.2, such as a bore. A cylindrical insert 5.3 can be inserted into this bore 5.2 to prevent dirt from entering the interior of the profile 9 when assembled.

[0068] Together, the locking pin 14 and the counter element 5 form a hinge-side locking device 400. As can be seen in Figure 6, when the sash 8 is closed, the locking pin 14 engages through the recess 5.2 into the insert 5.3 of the counter element 5 and thus secures the sash 8 against tampering.

[0069] It should be clear that the scope of protection of the present invention is not limited to the described embodiments. In particular, the construction of the sash or frame profile, and of the hinge, especially the mounting part and the locking element, can be modified without altering the core of the invention.
