Description

Technical Field

[0001] This invention relates to a concealed hinge device for rotatably fixing a door or window sash to a door or window frame about a hinge axis, comprising a housing and a box partially disposed within the inner cavity of the housing, wherein a hinge bracket is inserted into a receiving area of ​​the box along a horizontal direction orthogonal to the hinge axis. Furthermore, this invention also relates to a method for adjusting the hinge device. Background Technology

[0002] Such hinge devices are known in the prior art and are used to rotatably support door or window sashes to a door or window frame. The hinge device typically has a hinge bandlasche on the sash side and a hinge bracket on the frame side, the hinge bracket being rotatably supported about a hinge axis in a receptacle on the frame side of the hinge device. To enhance aesthetics and 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 within a recess in the frame. Concealed hinge devices are discussed here.

[0003] The hinge blade is typically fixedly connected to the wing, for example, via a threaded connection. The hinge bracket is in turn connected to the hinge blade. It is known in the prior art that the hinge bracket is connected to the housing of the hinge blade. The housing is adjustablely connected to a component of the hinge blade that is fixedly arranged on the wing. This enables a hinge device oriented in a vertical direction parallel to the hinge axis and in a horizontal direction orthogonal to the vertical direction for accommodating a door or window sash.

[0004] To properly adjust a door or window sash, it needs to be adjusted in all three spatial directions. For this purpose, the housing needs to be adjusted horizontally (in other words, in a direction orthogonal to the hinge axis) and, with the window or door closed, along the main extension direction of the door or window sash. Additionally, the housing needs to be adjusted vertically (in other words, along the hinge axis). Besides the horizontal and vertical adjustments, the hinge assembly must also be adjusted along the sealing pressure direction. In this invention, the sealing pressure direction is arranged orthogonally to both the horizontal and vertical directions.

[0005] With the door or window closed, adjusting the door or window sash in the direction of the sealing pressure causes the door or window sash to move toward or away from the seal of the door or window frame. It is known from the prior art that moving the frame-side receiving portion of the hinge device in the direction of the sealing pressure for adjustment can sometimes be quite complex. Summary of the Invention

[0006] The object of the present invention is to provide a hinge device in which comfortable and simple adjustment can be made along the direction of sealing pressure.

[0007] This task is accomplished by the hinge device given in claim 1.

[0008] The concealed hinge device according to the invention comprises a hinge bracket having a screw and a set screw for adjusting the hinge support in a sealing pressure direction orthogonal to the hinge axis and orthogonal to the horizontal direction. The screw is arranged in a first through hole in the fixed area and in a first threaded hole in the hinge bracket. In other words, the first through hole and the first threaded hole are aligned along the first screw insertion direction.

[0009] The screw head is disposed abuttingly on a contact surface facing away from the hinge bracket. Specifically, the lower surface of the screw head rests against the contact surface. Furthermore, it is specifically stipulated that the first through hole is unthreaded. This advantageously allows the hinge bracket to move relative to the fixed region in the opposite direction of the first screw insertion by rotating the screw. Moreover, the movement of the hinge bracket away from the fixed region is restricted by the screw screwed into the first threaded hole.

[0010] According to the invention, the set screw is arranged in a series of second threaded holes in the fixed region and is abutted against the hinge bracket. In other words, the set screw can be moved relative to the hinge bracket by rotation. The set screw abutting against the hinge bracket restricts the movement of the hinge bracket toward the fixed region. If the set screw abuts against the hinge bracket and is not rotated, the hinge bracket is fixed in the sealing pressure direction. If the set screw is rotated so that it is no longer abutting against the hinge bracket but spaced away from it, the hinge bracket can be moved toward the fixed region in the sealing pressure direction by screwing the screw into the first threaded hole. If the screw is partially unscrewed from the first threaded hole, the hinge bracket can be moved away from the fixed region in the sealing pressure direction by screwing the set screw into the second threaded hole. Therefore, the hinge device according to the invention enables advantageous and simple adjustment in the sealing pressure direction and secure fixation of the hinge bracket in the sealing pressure direction.

[0011] Advantageous aspects and further improvements of the invention can be found in the dependent claims and the description with reference to the accompanying drawings.

[0012] According to a preferred embodiment of the invention, the screw is configured to be screwed into a first threaded hole in a first screw-in direction, and the set screw is configured to be screwed into a second threaded hole in a second screw-in direction. The first and second screw-in directions each have a directional component along the sealing pressure direction. This advantageously achieves good force transmission along the sealing pressure direction from the screw-in screw or the set screw to the hinge bracket. In particular, it is specified that the first and second screw-in directions are arranged parallel to each other.

[0013] Preferably, the receiving area is configured to taper horizontally relative to the sealing pressure direction. This allows the hinge bracket to be securely supported within the receiving area of ​​the housing, while also allowing adjustment along the sealing pressure direction. In other words, the receiving area is wider on the frame side than on the side facing away from the frame. The hinge bracket, inserted into the receiving area with its front end, can thus be swiveled about an axis located at its front end within the receiving area for positioning along the sealing pressure direction. Therefore, adjustment of the hinge bracket relative to the housing along the sealing pressure direction is achieved by means of screws and set screws, with the axis parallel to the hinge axis located at the front end of the hinge bracket, through swiveling movement about this axis.

[0014] Therefore, it is preferably specified that the first and second screw-in directions are arranged obliquely relative to the sealing pressure direction. More preferably, the first and second screw-in directions each have a horizontal directional component, wherein neither has a directional component parallel to the hinge axis. This advantageously achieves excellent force transmission from the screw or set screw to the hinge bracket. When the hinge bracket is positioned along the sealing pressure direction, the force introduction from the screw to the thread of the first threaded hole or from the set screw to the surface of the hinge bracket would occur at an unfavorable angle (i.e., a non-orthogonal angle) when the first or second screw-in direction is arranged parallel to the sealing pressure direction due to the swinging motion of the hinge bracket during positioning.

[0015] A particularly preferred embodiment of the invention specifies that the hinge device is an adjustable hinge bracket along the sealing pressure direction with an additional first set screw, wherein the additional first set screw is arranged abuttingly on the hinge bracket in a series of third threaded holes in the fixing region. The additional first set screw is configured to be screwed into the third threaded holes along a third screw-in direction, wherein the third screw-in direction preferably has a directional component along the sealing pressure direction. In particular, it is conceivable that the third screw-in direction is arranged obliquely to the sealing pressure direction, wherein the third screw-in direction preferably has a directional component along the horizontal direction, and particularly does not have a directional component parallel to the hinge axis. This advantageously allows for the introduction of force symmetrically and therefore uniformly along the vertical direction for adjusting the hinge bracket along the sealing pressure direction. Preferably, the third screw-in direction is arranged parallel to the second screw-in direction.

[0016] For this purpose, it is preferably specified that the screw is arranged between the set screw and the additional first set screw, relative to a vertical direction parallel to the hinge axis. The vertical arrangement of the set screws on both sides of the screw can compensate for and prevent the hinge device from tilting.

[0017] According to another preferred embodiment of the invention, the first threaded hole, the second threaded hole, and the third threaded hole are centrally arranged along a straight line parallel to the hinge axis. Since the set screw and the screws have no horizontal spacing, the force introduced for positioning the hinge bracket in the sealing pressure direction is locally very limited. Therefore, deformation of the hinge bracket in the horizontal direction and the resulting inaccuracies in hinge bracket positioning are avoided. This advantageously improves the orientation and fixation of the hinge bracket in the sealing pressure direction.

[0018] For horizontal adjustment of the hinge mechanism, it is preferably specified that the housing has an upper housing portion and a lower housing portion. For this purpose, the housing preferably has a fourth threaded hole and an additional first screw, wherein the additional first screw is screwed into the fourth threaded hole, and the additional first screw is disposed abutting against the upper housing portion by an additional first screw head, and abutting against the lower housing portion by a first rod end. It is conceivable that the housing has a fifth threaded hole spaced vertically from the fourth threaded hole and an additional second screw, wherein the additional second screw is screwed into the fifth threaded hole, and wherein the additional second screw is disposed abutting against the upper housing portion by an additional second screw head, and abutting against the lower housing portion by a second rod end.

[0019] It is conceivable that the upper housing portion and the lower housing portion are threadedly connected to each other. It is also conceivable that the additional first screw head and the additional second screw head are arranged abuttingly on the bottom surface of the cover of the upper housing portion facing the lower housing portion. Particularly preferably, the cover is provided with a first opening for operating the first drive profile of the additional first screw head and a second opening for operating the second drive profile of the additional second screw head, wherein the first and second openings are, in particular, elongated holes.

[0020] In other words, the additional screw rests against the housing, such that when the additional screw is turned, the housing within the housing cavity moves toward the upper housing portion or toward the lower housing portion. This advantageously allows for high-precision adjustment of the housing and subsequent fixation of the housing in the horizontal direction. Although it is intuitive to move the housing horizontally by turning the additional screw, once the additional screw is no longer actively turned, the housing is fixed in its horizontal position by the friction of the additional screw against the housing. Preferably, the first rod end and / or the second rod end are flat or rounded.

[0021] The threaded connection between the upper and lower housing portions achieves a secure yet detachable connection between them. In particular, this threaded connection allows for horizontal adjustment of the space available for additional screws, ensuring that the screw heads and tips rest against the upper and lower housing portions. This advantageously ensures, reduces, or even prevents, horizontal gaps in the housing. Alternatively or additionally, it is conceivable that the upper and lower housing portions are bonded or clamped together.

[0022] The opening in the upper housing portion exposes only the drive profile of the corresponding additional screw, and is small enough that the portion of the additional screw head arranged around the drive profile rests against the bottom surface. Particularly advantageous here is that the additional screw will not fall out of the housing; that is, it is securely arranged within the housing. The opening is shaped as an elongated hole, which advantageously ensures the accessibility of the additional screw when the housing is positioned differently along the vertical direction.

[0023] According to another preferred embodiment of the invention, the housing has a series of sixth threaded holes for screwing in an additional second set screw in a first direction and a series of seventh threaded holes for screwing in an additional third set screw in a second direction. For this purpose, the additional second set screw and / or the additional third set screw are arranged abuttingly on a fixing region disposed relative to the hinge axis between the screwed-in additional second set screw and the screwed-in additional third set screw. The first direction has a horizontal directional component and a vertical directional component. The second direction has a horizontal directional component and a directional component opposite to the vertical direction. It is conceivable that the fixing region has a first groove and a second groove, wherein the first groove and the second groove are arranged to extend in a horizontal direction. Preferably, the first groove and the second groove have a V-shaped cross-section, wherein the additional second set screw abuts in the first groove and / or the additional third set screw abuts in the second groove. By screwing the additional second set screw into the sixth threaded hole or the additional third set screw into the seventh threaded hole, the portion of the housing arranged between the screwed-in set screws, and thereby the entire housing, can be adjusted vertically. The sixth and seventh threaded holes, extending at an angle relative to the vertical direction, allow the starting point for vertical adjustment of the housing to be located within a door or window sash. However, good accessibility from the outside is still ensured.

[0024] These grooves advantageously improve the vertical fixation of the housing and the actuation during vertical adjustment. These grooves increase the contact surface of the additional second and third set screws on the fixing area of ​​the housing. This significantly improves the force transmission between the set screws and the housing. Furthermore, the grooves facilitate guiding the additional second and third set screws on the surface of the fixing area of ​​the housing during both vertical and horizontal adjustment.

[0025] For this purpose, it is preferably specified that the additional second set screw and the additional third set screw each have a pointed or tapered end. Specifically, the additional second set screw with a pointed or tapered end is disposed abuttingly in the first groove, and / or the additional third set screw with a pointed or tapered end is disposed abuttingly in the second groove. The pointed or tapered ends of the additional second and third set screws advantageously further enlarge the contact surface within the groove of the housing's fixing area. This results in improved force transmission.

[0026] Another subject matter for accomplishing the task presented at the beginning is to provide a method for adjusting a hinge device according to the invention. To adjust the orientation of the housing in the sealing pressure direction, the screw is screwed into a first threaded hole, wherein the set screw, and preferably the additional first set screw, is screwed into a second or third threaded hole until the set screw or the additional first set screw is abutted against the hinge support. To adjust the orientation of the housing against the sealing pressure direction, the screw is partially unscrewed from the first threaded hole, wherein the set screw, and preferably the additional first set screw, is screwed into a second or third threaded hole until the set screw or the additional first set screw is abutted against the hinge support.

[0027] By screwing the screw into the first threaded hole and placing the screw head against the contact surface of the fixing area, the hinge bracket is tensioned toward the fixing area. If the screw is not turned, it prevents the hinge bracket from moving against the sealing pressure direction. The set screw against the hinge bracket, and preferably another first set screw against the hinge bracket, are responsible for fixing the hinge bracket in the sealing pressure direction. This provides an advantageously simple yet highly precise possibility for adjusting the hinge device in the sealing pressure direction. Preferably, to adjust the orientation of the housing in the sealing pressure direction, the set screw is first unscrewed from the hinge bracket before screwing the screw into the first threaded hole, and particularly preferably, the other first set screw is unscrewed from the hinge bracket.

[0028] According to another preferred embodiment of the present invention, in order to adjust the orientation of the housing in the vertical direction, in the first step, the additional third set screw is unscrewed from the fixing region in the opposite direction to the second direction. Then, in the second step, the additional second set screw is screwed into the fixing region along the first direction towards the direction of the additional third set screw. In the subsequent third step, the additional third set screw is screwed into the second direction until it is pressed against the fixing region.

[0029] By screwing in the additional second or third set screw at an angle relative to the vertical direction, an easy-to-operate mechanism for driving the housing vertically is created. Advantageously, the housing can be adjusted vertically and then fixed vertically. The housing is moved toward the additional third set screw by first unscrewing the additional third set screw from the fixing area of ​​the housing between the additional second and third set screws. Then, in a second step, the housing is moved vertically toward the additional third set screw by screwing in the additional second set screw. In a third step, the additional third set screw is finally screwed toward the fixing area of ​​the housing between the additional second and third set screws until the additional third set screw is against the housing. This contact of the additional second and third set screws against the housing fixes the housing vertically.

[0030] According to another preferred embodiment of the invention, the additional first screw and the additional second screw are rotated to orient the housing in a horizontal direction. This advantageously allows for intuitive, simple, and accurate adjustment of the housing's horizontal orientation. By rotating the additional first screw or the additional second screw, the housing is moved horizontally relative to the casing. Possible tilt positions of the housing can be compensated for by rotating the additional first screw and the additional second screw more or less accordingly.

[0040] In the accompanying drawings described below, the same elements are always represented by the same numbers and letters, and therefore are not necessarily described multiple times. Detailed Implementation

[0041] Figure 1 A side view of a hinge device 100 according to an exemplary embodiment of the present invention is shown, for rotatably securing a door or window sash (not shown) to a door or window frame (not shown) about a hinge axis S. The hinge device 100 shown is a concealed hinge device 100. This means that the hinge axis S is arranged within a recess in the door or window frame. The hinge bracket 4 of the hinge device 100 is rotatably connected to the door or window frame about the hinge axis S via a receiving portion (not shown) on the frame side.

[0042] The hinge bracket 4 is inserted horizontally H into the housing 3 of the hinge device 100 (see...). Figure 2 , 3 And 5), and fixed to the fixing area 3' of the housing 3 with screws 6. Here, the housing 3 is only partially visible because it is partially arranged in the shell, which has an upper shell part 1 and a lower shell part 2 threadedly connected to the upper shell part 1. Only the fixing area 3' protrudes from the channel of the upper shell part 1 in the opposite horizontal direction. The upper shell part 1 has a shell cover 1.1, which closes the upper shell part 1 in the opposite horizontal direction H.

[0043] As can be seen, the screw head 6.1 of screw 6 is positioned close to the contact surface 7.3 of the fixing area 3' (see...). Figure 2Screw 6 is arranged between set screw 8 and another first set screw 10 in a vertical direction V parallel to the hinge axis S. Set screw 8, screw 6, and the other first set screw 10 are arranged at the same height relative to the horizontal direction H.

[0044] exist Figure 1 The document also marks the first section I, the second section II, and the third section III, which are located in... Figure 2-4 As shown in the image.

[0045] Figure 2 A preferred embodiment of the invention is shown. Figure 1 The first sectional view of the hinge device 100 is shown. This is a sectional view along the first section I. The hinge bracket 4, rotatably supported about the hinge axis S, can be seen. In this illustration, the hinge axis S is arranged orthogonally to the plane of the paper. The hinge bracket 4 is inserted horizontally H into the receiving area 5 of the housing 3. It can be clearly seen that the housing 3 is arranged within the cavity of the housing formed by the upper housing portion 1 and the lower housing portion 2. The hinge bracket 4 is secured in the receiving area 5 of the housing 3 by screws 6, preventing it from sliding out of the receiving area 5 against the horizontal direction H.

[0046] For this purpose, screw 6 is screwed into the fixed region 3' through the first through hole 7.1 and the first threaded hole 7.2 along the first screwing direction A. The screw head 6.1 rests against the contact surface 7.3 of the fixed region 3' with its bottom surface. The first through hole 7.1 is preferably unthreaded. If screw 6 is screwed into the first threaded hole 7.2 along the first screwing direction A, the screw head 6.1 is supported on the contact surface 7.3, and the hinge bracket 4 is tensioned along the sealing pressure direction D, which is orthogonal to the hinge axis S and the horizontal direction H. Therefore, the adjustment of the hinge bracket 4 relative to the housing 3 along the sealing pressure direction D is achieved by arranging screw 6 on the fixed region 3' and by oscillating about an axis arranged parallel to the hinge axis S on the front end of the hinge bracket 4.

[0047] To allow the hinge bracket 4 to move along the sealing pressure direction D, the receiving area 5 is configured to taper in the horizontal direction H. To achieve optimal force transmission from the rotated screw 6 to the hinge bracket 4 for adjusting the hinge device 100 along the sealing pressure direction D, the first screwing direction A has an angle relative to the sealing pressure direction D.

[0048] However, the hinge bracket 4 shown is not fixed in the direction of the sealing pressure D by the screw 6. To fix the hinge bracket 4 in the direction of the sealing pressure D, a [further details are needed]. Figure 3 Set screw 8 is shown. Figure 3 A preferred embodiment of the invention is shown in cross-sectional view. Figure 1The hinge assembly 100 is shown. A second cross-section II is shown. The set screw 8 is screwed into the second threaded hole 9 in the fixing region 3' along the second screw-in direction B and rests against the hinge bracket 4. The set screw 8 resting against the hinge bracket 4 restricts the movement of the hinge bracket 4 along the sealing pressure direction D. Due to the screw 6 (see...) Figure 2 The hinge bracket 4 is fixed against the sealing pressure direction D, and the set screw 8 is attached to the hinge bracket 4, thereby preventing movement along the sealing pressure direction D. Therefore, the hinge bracket 4 is fixed along the sealing pressure direction D.

[0049] Figure 1 The additional first set screw 10 shown is screwed into the third threaded hole 11 (see...) Figure 4 and Figure 5 It also rests against the hinge bracket 4. A screw 6 is arranged between the set screw 8 and the other first set screw 10 to achieve symmetrical force transmission from the screw 6, the set screw 8 and the other set screw 10 to the hinge bracket 4.

[0050] Figure 4 It shows Figure 1 The third sectional view of the hinge assembly 100 is shown. Section III is shown. Here, the additional first set screw 10 can be seen, which is arranged abuttingly on the fixing region 3'. Screw 6 is arranged between the set screw 8 and the additional first set screw 10. This forms a stable fixation of the hinge bracket 4 in the sealing pressure direction D. Furthermore, the additional first screw 14.1 with an additional first screw head 14.3 can be seen through the first opening 15.1, and the additional second screw 14.2 with an additional second screw head 14.4 can be seen through the second opening 15.2. The additional first screw 14.1 and the additional second screw 14.2 are used for horizontal adjustment of the hinge assembly (see...). Figure 5 ).

[0051] Figure 5 It shows Figure 1 An exploded view of a portion of the hinge assembly 100 is shown. The hinge bracket 4 is omitted here. The upper housing portion 1 is clearly visible, which is screwed together with the lower housing portion 2 by connecting screws 19 to form the housing. A housing 3 is arranged within the cavity of the housing. The first through hole 7.1, the second threaded hole 9, and the third threaded hole 11 of the fixing area 3' of the housing 3 are clearly visible. A set screw 8, screwed into the second threaded hole 9 along the second screwing direction B, and the additional first set screw 10, screwed into the third threaded hole 11 along the third screwing direction C, are also shown. The third screwing direction C is arranged parallel to the second screwing direction B.

[0052] For horizontal adjustment of the hinge device 100, the hinge device 100 has the additional first screw 14.1 and the additional second screw 14.2, wherein the additional first screw 14.1 is screwed into the housing 3 in the horizontal direction H through a fourth threaded hole 13.1, and the additional second screw 14.2 is screwed into the housing 3 in the horizontal direction H through a fifth threaded hole 13.2. The additional first screw head 14.3 of the additional first screw 14.1 abuts against the inner surface of the cover 1.1. Furthermore, the first shank end 14.5 of the additional first screw 14.1 abuts against the lower housing portion 2. The drive profile of the additional first screw head 14.3 can be operated externally through a first opening 15.1 in the cover 1.1. The additional second screw head 14.4 of the additional second screw 14.2 abuts against the inner surface of the cover 1.1. Furthermore, the second shank end 14.6 of the additional second screw 14.2 abuts against the lower housing portion 2. The drive profile of the additional second screw head 14.4 can be operated externally through the second opening 15.2 in the cover 1.1. If the additional first or second screws 14.1, 14.2 are turned, the housing 3 and the hinge bracket 4 together with the housing 3 move horizontally in the direction H toward the upper housing portion 1 or toward the lower housing portion 2.

[0053] To adjust the hinge device 100 along the vertical direction V, a second set screw 17 and a third set screw 18 are provided. The second set screw 17 is screwed into the sixth threaded hole 16.1 along the first direction E, and its tapered end rests against the first groove 20, which is arranged in a V-shape along the horizontal direction H in the fixed area 3'. The third set screw 18 is screwed into the seventh threaded hole 16.2 along the second direction F, and its tapered end rests against the second groove 21, which is arranged in a V-shape along the horizontal direction H in the fixed area 3'. The fixed area 3' is located between the second set screw 17 and the third set screw 18. To move the housing 3 along the vertical direction V, the third set screw 18 is first unscrewed from the fixed area 3'. Then, the second set screw 17 is screwed into the fixed area 3' along the first direction E. Thus, the housing 3 moves along the vertical direction V. If the housing 3 is correctly positioned in the vertical direction V, the additional third set screw 18 is screwed in along the second direction F until it abuts against the groove 21 in the fixing area 3'. The first direction E has a directional component along the vertical direction V and a directional component along the horizontal direction H. The second direction F has a directional component along the horizontal direction H and a directional component opposite to the vertical direction V. By arranging the first direction E at an angle to the vertical direction V and the second direction F at an angle to the vertical direction V, the optimal abutment surfaces of the additional second or third set screws 17, 18 are achieved, while still allowing good external access to the additional second or third set screws 17, 18.
