Description

[0001] This invention relates to a hinge component for a hinge device, particularly a hinge component for a concealed hinge device for rotatably fixing a door or window sash to a door or window frame about a hinge axis, comprising a fixing component for fixing to the sash or frame and a hinged component for connecting to a hinge pin. Furthermore, this invention relates to a hinge device.

[0002] Such hinge components and hinge devices are known from the prior art in various variations. They are used to rotatably support door or window sashes to a door or window frame. Hinges typically have hinge components on the sash side and hinge components on the frame side. The frame-side hinge component usually includes a hinge member, also called a hinge bow, which is rotatably supported about a hinge axis in a receptacle on the frame side of the hinge device. Typically, the sash-side mounted hinge component generally includes only one fixed member and one hinge member as a connecting member to a hinge pin located in the hinge axis. To improve aesthetics and to optimize the use of available space, the components of the hinge device, particularly the receptacle on the frame side and the hinge axis, can be arranged in recesses in the frame, mostly the frame profile. Here, those skilled in the art refer to this as a concealed hinge device.

[0003] Typically, the first and second hinge components are securely threaded to the sash or frame via at least a fixed section. The hinge bow of one hinge component is usually rotatably supported on its fixed section and connected to the other hinge component. Especially in the case of concealed hinges, a compromise often must be made between optimal aesthetics and the ease of installation. Therefore, the component that fits into the recess of the frame partially hinders comfortable installation of the system.

[0004] In particular, it has been shown that, for sufficient accessibility and a relatively large amount of free space, especially for reliable and relatively comfortable installation, it is necessary to secure the hinge components to the sash or frame with their corresponding fixing sections. Furthermore, securing the hinge components with screws requires the installer to pay close attention, especially to ensure the screws properly engage with the corresponding frame or sash profiles. In some cases, pre-drilling holes in the sash or frame is also necessary for screw engagement. This also typically requires ample accessibility.

[0005] Therefore, the objective of this invention is to provide a hinge component and a hinge device that improves upon at least one of the aforementioned disadvantages and, in particular, simplifies the installation and adjustment of the hinge.

[0006] The present invention solves the proposed task by a hinge component having the features of the independent claim and by a hinge device having the features of claim 14. Advantageous embodiments and improvements of the invention are disclosed in the dependent claims, the description, and the drawings.

[0007] In the hinge component according to the invention, for fixing to a sash or frame, the fixing component has a form-locking member and a locking screw, wherein the locking screw can establish an active connection with the form-locking member. This active connection allows the form-locking member and the locking screw to interact, particularly for achieving a clamping effect. This allows the hinge component to be installed on one of the sash or frame in a particularly simple manner, especially without requiring a particularly large free space for sufficient accessibility.

[0008] The form-locking component and the locking screw together can form a form-locking connection between the hinge component and one of the sash and frame. In this way, the hinge component can be form-locked to the sash or frame by means of the form-locking component—which forms a first form-locking area—and the locking screw—which forms a second form-locking area. The form-locking connection can obviously be achieved by rotating and advancing the locking screw relative to the hinge component. In particular, the second form-locking area can be formed with the locking screw protruding, or it can be inconspicuous with the locking screw screwed in. This makes it possible to mount the hinge component onto one of the sash and frame in a particularly simple manner.

[0009] To enable precise positioning of the hinge components and locking screws onto the sash or frame, particularly onto the strip to be gripped from the rear, in the simplest possible manner, the hinge components may have a bulge or protrusion on their outer surface, which faces the strip during installation, and on this outer surface, the locking screw—which functions as a form-locking component—can be screwed out from a threaded hole. The protrusion is preferably constructed to completely surround the opening of the threaded hole. Alternatively, the protrusion may be a bulge partially constructed only in the area of ​​the opening of the threaded hole. The protrusion may be configured such that it also at least partially grips the rear of the strip on the sash or frame during installation. To simplify the engagement or insertion of the protrusion behind the strip, it is laterally rounded. Thus, the protrusion primarily functions as a guide element. Furthermore, the protrusion can be used to temporarily hold or secure the hinge components to the sash or frame. After the protrusion is engaged behind the strip, further form-locking can be achieved during installation using the locking screw, thereby securing the hinge components to the sash or frame.

[0010] Preferably, the form-locking component and the locking screw are in an active connection, allowing the fixing component to be secured to the sash or frame not only by form-locking but also by clamping. For this purpose, by unscrewing the locking screw, the hinge component can be secured to one of the sash or frame by both form-locking and clamping. In particular, the fixing component to the sash or frame can be achieved solely by clamping. This is especially possible when the locking screw is not threaded into the sash or frame. This allows for both improved mounting and a particularly stable and reliable fixation of the hinge component to the sash or frame.

[0011] To further optimize the locking mechanism, the shape-locking component may have a protruding gripping section for gripping the corresponding profile component on the sash or frame from the rear. The profile component may, for example, be a first strip component with an undercut. Thus, during installation, the hinge component can be hooked onto the rear of the strip component of the sash or frame profile using the gripping section and held at least temporarily by the profile. A locking screw here secures the shape-locking component in the shape-locking connection.

[0012] Preferably, the shape-locking member has a groove-shaped recess between the gripping section and the hinge member, into which the first strip member can engage. By forming a recess next to the protruding gripping section, improved force transmission is achieved. The recess can be configured to open towards the hinge member of the second hinge member or towards the first strip member. Thus, the hinge member can be easily hooked behind the strip member of the fan or frame profile during installation and is at least temporarily secured.

[0013] The groove-shaped recess can in particular have an insertion opening through which the first strip component can be inserted into the groove-shaped recess in the insertion direction. The insertion direction is advantageously oriented perpendicular to the hinge axis. Thus, the shape-locking component with the gripping section can be hooked into or behind the strip component in a particularly simple manner.

[0014] To withstand particularly large forces, the shape-locking component preferably extends along the entire length of the hinge component in the direction of the hinge axis. This makes it possible to have a particularly large contact surface, allowing particularly high forces to be transmitted from the hinge component to the frame, and thus the hinge component is also suitable for hinges of particularly heavy fans.

[0015] According to a preferred embodiment of the invention, a locking screw is provided on the hinge component in such a way that it can grip the rear of a second strip member, particularly one with an undercut, which is arranged opposite to the first strip member of the sash or frame. Here, the second strip member is typically constructed on the same member as the first strip member, particularly on a profile. The second strip member can be constructed opposite to and / or mirror-image of the first strip member. Accordingly, the portion of the locking screw forming the second shape-locking region is also constructed opposite to and / or mirror-image in mode of action of the shape-locking member forming the first shape-locking region. Thus, the locking screw can be constructed as a component of the shape-locking connection between the hinge component and one of the sash or frame. In particular, the locking screw can therefore be constructed as a displaceable shape-locking element. This makes a particularly stable and reliable connection between the hinge component and the sash or frame possible. Furthermore, the locking screw enables a particularly effective fixation of the hinge component to the sash or frame.

[0016] Preferably, the locking screw is arranged on the hinge component in such a way that at least its end portion can grip the rear of the second strip component. This means that the end portion of the locking screw forms part of the aforementioned second shape-locking area, also known as the second shape-locking area, of the shape-locking connection between the hinge component and the sash or frame. The locking screw can protrude from the fixing member of the hinge component and—without being screwed into the sash or frame—secure the hinge component to the sash or frame. The hinge component can be clamped between the first strip component and the second strip component. Here, clamping is achieved, in particular, by the engagement of the gripping portion of the shape-locking component and the locking screw. This allows for both improved installation and a particularly stable and reliable fixation of the hinge component to the sash or frame.

[0017] The locking screw can be arranged on the hinge component in such a way that the second hinge component can be advanced by means of the locking screw in a direction opposite to the insertion direction of the first belt component, and particularly the gripping section can be advanced to the rear of the first belt component. Therefore, by unscrewing the locking screw and subsequently supporting it on the second belt component, the gripping section is moved until it is completely behind the first belt component, or until the first belt component is fully received in the groove-like recess, thereby achieving particularly effective clamping of the hinge component.

[0018] In order for the locking screw to mate with the form-locking component, the locking screw needs to have a specific arrangement and orientation. Therefore, the threaded hole in the locking screw and / or hinge component that engages with the locking screw extends laterally through the hinge component, such that the locking screw's head, which has a tool receptacle, faces the first side of the hinge component facing the hinge member, and its opposing screw end faces the second side of the hinge component facing away from the hinge member. This allows the locking screw to operate on both the side facing the sash or frame and the side facing away from the sash or frame.

[0019] It has been shown that the locking screw is advantageously arranged at an angle relative to the first side, the second side, and / or the insertion direction in the longitudinal extension dimension. This angle should be understood in particular as an angle between 15° and 75°. Thus, the locking screw is particularly suitably arranged and oriented to achieve a clamping effect while maintaining good accessibility for operation.

[0020] Furthermore, it has been shown that it can be advantageous if the locking screw is arranged perpendicular to the hinge axis in the longitudinal extension dimension. This allows for the transmission of particularly large forces between the hinge components and the sash or frame.

[0021] In the hinge device according to the invention, particularly a concealed hinge device for rotatably fixing a door or window sash to a door or window frame about a hinge axis, a first hinge component that can be fixed to one of the sash and the frame, and a second hinge component that can be fixed to the other of the sash and the frame, the first hinge component comprising a mounting member forming a housing section having a receiving area, and a first articulating member that is at least partially arranged in the receiving area and rotatable about the hinge axis. This makes a particularly space-saving and easy-to-install hinge device possible.

[0022] According to a preferred embodiment of the invention, the second hinge component comprises a fixing component and a second hinge member, the second hinge member being fixed to the first hinge member of the first hinge component. The hinge member is formed, in particular, by those components that together form the hinge bow. This—particularly releasable—connection of the hinge member in the region of the hinge member, i.e., the region of the hinge bow, enables particularly good accessibility for mounting the two hinge members on a sash or frame, thereby enabling a particularly comfortable and reliable installation.

[0023] Preferably, the first hinge component and the second hinge component are arranged to at least partially overlap. This enables a particularly stable and reliable connection between the two hinge components in the region of the hinge component. Furthermore, it improves accessibility during installation, especially when securing the hinge components to the sash or frame.

[0024] Particularly preferably, a slit-like housing is constructed or arranged on one of the first and second hinge components, into which at least one coupling segment of the other hinge component can be introduced and secured. Thus, for installation, one hinge component can be pushed into the housing constructed on the other hinge component. Consequently, the two hinge components can be installed in a particularly simple manner and secured to each other with particularly reliable stability.

[0025] The first hinge component is preferably secured to the second hinge component by means of at least one hinge component fastening screw, which is arranged, in particular, perpendicular to the hinge axis in the longitudinal extension dimension. Particularly preferably, two hinge component fastening screws are provided. These screws can extend through the aforementioned housing. This enables a particularly stable and reliable connection between the two hinge components in the region of the hinge component.

[0026] According to another preferred embodiment of the invention, the first and second hinge components are configured to be movable relative to each other, particularly adjustable, by means of a hinge component adjusting screw, especially a headless screw. Thus, adjustment of the hinge components can be performed directly on the hinge bow, which is generally easily accessible from the outside.

[0027] Particularly preferably, the hinge adjustment screw is arranged perpendicular to the hinge axis and the longitudinal extension of the hinge fastening screw. This makes particularly efficient adjustment and particularly reliable fastening possible.

[0028] According to another preferred embodiment of the invention, the housing segment is formed by at least three sidewalls of the mounting component, particularly three sidewalls arranged at an angle to each other in a direction extending longitudinally, especially the sidewalls of a single material block. The housing segment can, in particular, be integrally constructed. Thus, the hinge component structure is particularly space-saving and easy to install. In particular, the hinge component can also be inserted into and fixed in a small recess in the frame profile or fan profile. Furthermore, the manufacturing cost of this housing is particularly low.

[0029] Preferably, the mounting component is constructed as a long strip, particularly a long strip having at least two longitudinal segments angled to each other, especially a bent long strip. This allows the hinge component to be inserted and mounted particularly well into the frame or sash profile.

[0030] Particularly preferably, the mounting component has a fixing section on which it can be secured to one of the sash and the frame by means of a fixing mechanism. This fixing section specifically relates to a portion of the mounting component that differs from the housing section. The fixing section may, for example, be arranged laterally adjacent to the housing section, particularly outside a recess or indentation in the sash or frame profile, and especially on the end side of the frame facing the sash and easily accessible from the outside.

[0031] To improve the adjustability of the hinge components, at least one elongated hole can be constructed in the fixing section of the mounting component for a fixing mechanism to fix the mounting component to the fan profile or frame profile to extend through the elongated hole, so that the mounting component can be displaced relative to the fixing mechanism, in particular, in the longitudinal extension dimension of the mounting component.

[0032] According to another preferred embodiment of the invention, the first hinge component includes at least one adjusting member that can be fixed to one of the sash and the frame, particularly independently of the mounting component. Thus, most of the hinge's adjusting mechanism can be moved to a position easily accessible from the outside.

[0033] Preferably, the adjusting component has a mechanism for displacing the mounting component, particularly those mechanisms that allow displacement in a direction parallel or perpendicular to the hinge axis. These mechanisms may include, for example, an adjusting screw. This enables a particularly comfortable adjustability of the hinge.

[0034] Preferably, these mechanisms include at least one mounting member adjusting screw, which rests against the mounting member with its end portion, particularly against the end of the mounting member. The mounting member adjusting screw, for example, allows the entire mounting member to be moved relative to the adjusting member. This enables a particularly comfortable adjustability of the hinge.

[0035] Particularly preferably, at least one fixing mechanism of the mounting component extends additionally through a groove in the fixing section of the adjusting component. This enables a particularly comfortable adjustability of the hinge.

[0036] According to another preferred embodiment of the invention, the second hinge component is provided to have at least one feature according to any one of claims 1 to 13. In particular, it can be provided that, in order to secure the second hinge component to one of the sash and the frame, the second hinge component, particularly in the fixing section, has a shape-locking member with a gripping section for gripping from the rear a corresponding first strip component, particularly one with an undercut, constructed on one of the sash and the frame. For this purpose, the shape-locking member preferably extends along the entire length of the hinge component in the direction of the hinge axis. Preferably, the shape-locking member has a groove-shaped recess between the gripping section and the hinge component, particularly a recess opening toward and corresponding to the first strip component. Particularly preferably, the groove-shaped recess has an insertion opening through which the first strip component can be inserted into the groove-shaped recess in an insertion direction perpendicular to the hinge axis. According to an improved embodiment of the invention, a second hinge component is provided having at least one locking screw for gripping a second strip component of one of the sashes and frames from the rear. This second strip component is arranged on one of the sashes and frames, particularly opposite to the first strip component, and particularly having an undercut. The locking screw can be arranged on the second hinge component such that the second hinge component can be advanced behind the first strip component by means of the locking screw in a direction opposite to the insertion direction of the first strip component, particularly with a gripping section. The locking screw can be configured as part of a form-locking connection between the second hinge component and one of the sashes and frames. In particular, the locking screw can be arranged on the second hinge component such that at least its end portion can grip the rear of the second strip component. Preferably, the locking screw and / or the threaded hole engaging with the locking screw extends laterally through the second hinge component, such that the locking screw's head, having a tool receptacle, faces the first side of the second hinge component facing the hinge member, and its opposing screw end faces the second side of the second hinge component away from the hinge member. The locking screw can be arranged perpendicular to the hinge axis in the longitudinal extension dimension. Preferably, the locking screw is arranged obliquely relative to the first side, the second side, and / or the insertion direction in the longitudinal extension dimension. This allows for particularly comfortable installation and adjustment of the hinge device.

[0037] Particularly preferably, the first hinge member is constructed in an arc shape and / or a two-legged shape. The first hinge member may specifically have a first leg segment facing the hinge axis and a second leg segment facing the second hinge member. The first and second leg segments are preferably constructed to be flat, i.e., non-curved. A transition region may be provided between the first and second leg segments, connecting the two legs in an angle, arc, or rounding. The connection between the first and second leg segments extends particularly over the entire width of the first hinge member. With this arc-shaped construction, and particularly with the hinge member adjusting screws also potentially located on or within the second leg segment, an angle relative to the second hinge member can be arranged, enabling a particularly precise and effective adjustment of the horizontal and sealing pressure of the sash relative to the frame, especially without significant lateral displacement of the sash relative to the frame.

[0038] Preferably, an angle is formed between the first leg segment and the second leg segment, the angle being between 20° and 90°, more preferably between 35° and 75°, and particularly preferably between 50° and 60°. It has been shown that an angle of 50° to 60°, and especially 55°, formed between the first leg segment and the second leg segment enables optimal guidance and orientation of the adjusting screws of the hinge components used to adjust the horizontal pressure and sealing pressure of the sash relative to the frame.

[0039] Furthermore, it has been shown that it is advantageous if the first and second leg segments have substantially the same length. The length of the first leg segment extends in the direction between the transition to the second leg segment and the hinge axis. The length of the second leg segment extends in the direction between the transition to the first leg segment and the free end located on the coupling segment. This allows for particularly efficient force transmission through the first hinge member and enables particularly advantageous swaying of the sash relative to the frame.

[0040] The embodiments of the present invention will now be explained in more detail with the aid of the accompanying drawings. The same reference numerals denote the same parts. The drawings schematically illustrate: Figure 1 This is a perspective view of the hinge device of the present invention having a hinge component according to the present invention, shown in an exploded view; Figure 2 It is based on the fact that it is in the assembly state. Figure 1 The hinge mechanism; and Figure 3 It is in the installation state according to Figure 1 Side view of the hinge device.

[0041] The hinge device according to the invention, indicated by 1 in the accompanying drawings, is configured as a concealed hinge device for rotatably fixing a door or window sash 50 about a hinge axis S to a door or window frame 40. The hinge device 1 includes a first hinge component 1 that can be fixed to one of the sash 50 and the frame 40, and a second hinge component 2 that can be fixed to the other of the sash 50 and the frame 40. The second hinge component 2 corresponds to another aspect of the invention.

[0042] The first hinge component 1 includes a mounting component 10 and a first hinge member 11 that can rotate about the hinge axis S. The mounting component 10 and the hinge member 11 are constructed separately. In addition, the first hinge component includes two adjusting components 12a and 12b for adjustment purposes.

[0043] A hinge pin 8, defining a hinge axis S, is supported on the mounting member 10. For this purpose, the mounting member 10 includes a housing section 13 having a receiving region 14. The receiving region 14 specifically includes two opposing holes in which the hinge pin 8 is supported. The receiving holes 14 are arranged such that at least a portion of the first hinge member 11 is disposed within the housing section 13.

[0044] Here, the housing section 13 is formed by at least three sidewalls 10a, 10b, and 10c of the mounting member 10. The sidewalls 10a, 10b, and 10c are formed, in particular, by three sections of a long strip that are angled to each other along their longitudinal extension direction, and are particularly bent. Specifically, the entire mounting member 10 is constructed as a long strip. To form the housing section 13, the long strip has at least two longitudinal sections angled to each other that form the sidewalls 10a, 10b, and 10c.

[0045] To be fixed to one of the sash 50 and the frame 40, the mounting member 10 has a fixing section 16a, 16b adjacent to the housing section 13 along its longitudinal extension, on which the mounting member 10 can be fixed by means of fixing mechanisms 17, 17', 17'', 17'''. The fixing mechanisms 17, 17', 17'', 17''', configured as fastening screws, extend through elongated holes 18, 18', 18'', 18''' respectively arranged in the fixing sections 16a, 16b. Thus, for adjustment purposes, the mounting member 10 can be displaced relative to the fixing mechanisms 17, 17', 17'', 17''' or the sash 50 or the frame 40 along its longitudinal extension.

[0046] Two adjusting components 12a and 12b are used for vertical adjustment of the mounting component 10. For this purpose, adjusting components 12a and 12b are respectively secured to one of the sash 50 and frame 40 in the fixing section 25 independently of the mounting component 10. This securing is achieved by fastening screws 17, 17', 17'', 17''', which are also used to secure the mounting component 10. The screws 17, 17', 17'', 17''' extend through holes 24, 24', 24'', 24''' provided in the adjusting components 12a and 12b until they reach one of the sash 50 and frame 40, and hold the adjusting components 12a and 12b in position even when only slightly screwed into the sash 50 or frame 40—especially during adjustment. For adjusting the mounting component 10, a mechanism 19 is provided for displacing the mounting component 10 relative to adjusting components 12a, 12b positioned and fixed to one of the sash 50 and frame 40, particularly in a direction parallel or perpendicular to the hinge axis S. Here, the mechanism 19 includes, for each adjusting component 12a, 12b, mounting component adjusting screws 19, 19' arranged transversely to the extending direction of a fastening screw (not shown). The mounting component adjusting screws 19, 19' are configured as headless screws and have end portions 39, 39' facing the end side of the mounting component 10, which abut against the mounting component 10, particularly against the end portions 38, 38' of the end side of the mounting component 10. Furthermore, the mechanism 19 includes fixing screws 19'', 19''' for each adjusting component 12a, 12b.

[0047] The second hinge component 2 includes a fixing component 20 for securing to one of the sash 50 and the frame 40, and a hinge component 21. The fixing component 20 and the hinge component 21 are formed by connected, particularly integral, members. The fixing component 20 includes a form-locking component 3 and a locking screw 4, which together secure the second hinge component 2 to the sash 50 or the frame 40. For this purpose, the form-locking component 3 and the locking screws 4, 4' are in operative connection.

[0048] The shape-locking component 3 includes a protruding gripping section 31 and a groove-shaped recess 32. The gripping section 31 is used to grip from the rear a first strip component 41, which is correspondingly constructed on one of the fan 50 and the frame 40, and in particular has an undercut. Figure 3As shown. The groove-shaped recess 32 constructed between the gripping section 31 and the hinge member 21 provides a particularly stable fixing possibility. The recess extends along the entire length L of the hinge member 2 in the direction of the hinge axis S. Therefore, the first strip member 41 can be additionally fitted into this recess 32, so that the shape-locking member 3 can be particularly well fixed to the first strip member 41 of the fan 50 and the frame 40. For this purpose, the recess 32 is constructed to be open in the direction toward the first strip member 41. In particular, the groove-shaped recess 32 has an insertion opening 33 through which the first strip member 41 is inserted into the recess 32 in an insertion direction R1 perpendicular to the hinge axis S.

[0049] The locking screws 4 and 4' are used both to advance the second hinge component 2 toward the form-locking component 3, particularly to advance the gripping section 31 behind the first strip component 41, and to secure the second hinge component 2 to the sash 50 or frame 40 by means of clamping at the form-locking connection. For this purpose, the locking screws 4 and 4' engage with threads constructed on the second hinge component 2. Specifically, the locking screws 4 and 4' engage only with the threads of the second hinge component 2. Furthermore, the locking screws 4 and 4' are arranged on the second hinge component 2 such that at least one end region 5 of the locking screws 4 and 4'—which can protrude laterally from the second hinge component 2—can grip the rear of the second strip component 42 of the sash 50 or frame 40, and can be supported relative to the sash 50 or frame 40 in this region, particularly without being screwed into the sash 50 or frame 40. The locking screws 4 and 4' act as a spindle to advance the second hinge component 2 during further rotation, but only when they make end-side contact with the sash 50 or the frame 40.

[0050] The second strip component 42 is optimally arranged opposite to the first strip component 41, and in particular, is a mirror image of the first strip component 41. By rotating the locking screws 4 and 4' while simultaneously pushing the screws 4 and 4' out of the second hinge component 2 in a direction away from the second hinge component 2, the second hinge component 2 can be pushed forward in a direction opposite to the insertion direction R1 of the first strip component 41.

[0051] In order to accurately position the hinge component 2 on the frame 40 in the simplest possible way, the hinge component 2—such as Figure 3As shown, a protrusion 29 is present on the outer surface 28, which faces the strip member 42 during installation, and locking screws 4, 4' are screwed out from threaded holes 6, 6' on the outer surface 28. The protrusion 29 can be configured such that it also at least partially grips the rear of the strip member 42 during installation. Thus, the hinge member 2 can be held at least temporarily on the frame 40, particularly until further form-locking is achieved by rotating the locking screws 4, thereby securing the hinge member 2 to the frame 40.

[0052] To achieve effective advancement of the second hinge component 2, locking screws 4, 4' or threaded holes 6 engaging with locking screws 4, 4' are arranged such that they extend laterally through the second hinge component 2, and the screw heads 7 of the locking screws 4, 4', having tool receptacles, face the first outer surface 27 of the second hinge component 2 facing the hinge member 21, while the opposing screw ends 5, 5' face the second outer surface 28 of the second hinge component 2 facing away from the hinge member 21. The longitudinal orientation of the locking screws 4, 4' is specifically inclined relative to the first outer surface 27, inclined relative to the second outer surface 28, and inclined relative to the insertion direction R1, wherein "inclination" should be understood in particular as an angle between 15° and 75°. Here, the angle is approximately 45°.

[0053] The shape-locking component 3 and the locking screws 4 and 4' together form a shape-locking connection 9 between the hinge component 2 and the frame 40, particularly an openable shape-locking connection 9. Furthermore, the shape-locking component 3 and the locking screws 4 and 4' can be in an active connection such that the fixing of the fixing component 20 to the frame 40 is not only shape-locked but also clamped under force. Thus, as in... Figure 3 As can be particularly seen, the shape-locking mechanism shown therein can be formed by unscrewing the locking screws 4, 4' at their end faces 5, 5', and clamped under force by further rotation. Conversely, by screwing the locking screws 4, 4' into or out of the threaded holes 6, 6' constructed on the second hinge component 2, the shape-locking element formed under the end faces 5, 5' of the locking screws 4, 4' can be retracted, thereby completely releasing the shape-locking mechanism. The second hinge component can thus be secured to the sash 50 or frame 40 in a particularly simple manner.

[0054] To mount and adjust the sash 50 on the frame 40, the first hinge member 11 of the first hinge member 1 is releasably and adjustably fixed to the second hinge member 21 of the second hinge member 2. Here, the first hinge member 11 and the second hinge member 21 are arranged to at least partially overlap. Specifically, a slit-like housing 22 is constructed on the second hinge member 21, in which at least one coupling section 15 of the first hinge member 11 is introduced and fixed. The first hinge member 11 is fixed to the second hinge member 21 by means of two hinge member fastening screws 23a and 23b, which are arranged perpendicular to the hinge axis S in the longitudinal extension dimension. For adjustment, the first hinge member 11 and the second hinge member 21 can be displaced relative to each other by means of a hinge member adjusting screw 26 configured as a headless screw. The adjustment is particularly set along a direction perpendicular to the hinge axis S and perpendicular to the longitudinal extension dimension of the hinge member fastening screw 23. This makes both simple installation and particularly simple adjustment of the hinge possible.

[0055] As from Figure 1 and Figure 3 As can be particularly seen, the first hinge member 11 is constructed in a two-legged shape, having a first leg segment facing the hinge axis S (in Figure 1 In the area indicated by the arrow tip in Figure 11) and the second leg segment toward the second hinge component 2 (in Figure 1 (In the area indicated by the arrow tip in Figure 15). An arc or rounding is constructed between the first leg segment and the second leg segment. The angle between the first leg segment and the second leg segment is 50° to 60°, particularly 55°. This allows for optimal guidance and orientation of the hinge component adjusting screw 26 for adjusting the horizontal pressure and sealing pressure of the sash 50 relative to the frame 40. It can also be seen that the first leg segment has substantially the same length in the direction between the transition to the second leg segment and the hinge axis, and in the direction between the second leg segment and the transition to the first leg segment and the free end located on the coupling segment.

[0056] It should be understood that the scope of protection of this invention is not limited to the embodiments shown. In particular, the structure of the hinge device and hinge components—without changing the concept of the invention—can be modified entirely.
