Description

The invention relates to a hinge arrangement according to the preamble of claim 1 and according to the preamble of claim 2.

Such hinges are already known in a variety of configurations. So shows the WO 2011/006 682 A1 a band for the pivotable mounting of a sash on a frame. This hinge arrangement has two joint parts which can be pivoted relative to one another and which can be pivoted relative to one another about a common pivot axis. The swivel axis is formed by a housing and a swivel bracket engaging in it. The swivel bracket is a curved link follower that engages in a guide slot in the housing. The guide slot and swivel bracket are matched to one another in an arc shape and are the means for forming the swivel axis. The relative assignment of the housing and swivel bracket cannot be adjusted. Only a horizontal adjustment option is provided using spacer plates that can be inserted. Therefore, if the wing sags, no correction can be made.

To this end, the EP 2 245 251 B1 suggest that the hinge pin has a sleeve into which an inner pin engages with a flat rectangular cross-section. The pin sleeve can be adjusted with respect to the inner pin by means of a screw member, so that the effective axial length of the hinge pin can be adjusted. The disadvantage here is that, despite the large number of components used, manual adjustment has to be made, which is also often difficult to access with a built-in frame due to the reveal of the window opening.

From the DE 10 2007 024 742 A1 a window or a door has become known in which a sash is hinged to the frame via a hinge and a support device. Due to its structure, the joint can only absorb small vertical forces, so that the additional support device is intended to compensate for the weight forces of the wing. For this purpose, the support device is designed as a support arm mounted displaceably in the frame, which is rotatably assigned to the wing and is guided out of its support on the frame side when the wing is opened. As a result, the support arm has only a small contact surface in the frame-side guide when it is fully pivoted, which also penetrates deep into the frame material and thus greatly reduces the frame cross-section, while the load-bearing capacity is limited due to the large lever.

In order to ensure the relative position of hardware components, the EP 0 515 931 B2 known to a pivotably attached to the wing support arm in such a way with a spring force apply that its free end protrudes in the direction of the frame and hits a frame-side stop when the sash is closed, and is supported on it when the sash is closed, so that the end of the sash remote from the axis of rotation can be lifted into the frame. In connection with this it is through the EP 0 875 651 B1 also already known to automatically compensate for the horizontal position of the pivot axis of a hinge arrangement. The measures described above are used to align the downward sagging wing side remote from the axis of rotation, with the aim of enabling the wing to close. If the hinge axis is set over time, the measures described have no effect.

From the EP 1837472 A1 a window or a door with a hinge arrangement is known in which the hinge should have a design that is completely concealed in the rebate area and a relief device in the form of a support rod or a rope is provided to accommodate the sash weight. One of the ends of the relief device is connected in an elastic receptacle, so that the changed spatial assignments are compensated for in the event of a slight relative position adjustment of the sash and frame. It is disadvantageous that the elastic means, although not the path of the relief device, compensates for the actually decisive distance between the hinge band itself at the hinge points. As a result, the wear and tear on the hinge fittings is not relieved over time. In addition, the elastic restoring force must always be greater than the weight of the sash. This requires a corresponding adaptation of the elastic element to the sash weight, which entails individual adaptation or a large number of configurations.

The object of the invention is therefore to provide a hinge arrangement of the generic type which avoids the disadvantages of the prior art and combines a high load-bearing capacity with improved adjustment.

To solve this problem it is provided according to claim 1 that the first hinge part consists of a frame-side bearing block which has a guide contour that rises in the closing direction for a support arm of a wing bearing part of the second hinge part, which is guided therein and shaped according to the pivot axis, with an alignment element consisting of the Guide contour in which the support arm engages, brings about a functional axial alignment of the joint parts and a relief device is effective as an alignment element between the bearing block and the sash bearing part, the relief device being a pull rope which is effective between the bearing block and the sash bearing part, and at least one of the Support elements automatically compensates for a spacing between the support elements caused by the alignment element, and the support elements provide two wedge surfaces which are horizontally displaceable against each other.

An alternative solution according to claim 2 provides that the joint parts consist of a hinge sleeve and a pivot pin engaging in the hinge sleeve, which pivot pin forms the common pivot axis, the support elements consisting of the pivot pin and a pressure piece supported thereon and that an alignment element is a functional one brings about axial alignment of the joint parts and at least one of the support elements automatically compensates for a spacing between the support elements caused by the alignment element, the alignment element being a pivot lever which, when the sash is in the open position, is pivoted towards the frame and is supported on a stationary stop when the sash is closed .

The alignment element is essentially used for the relative alignment of the hinge components forming the pivot axis. The alignment element thus initially has the task of providing the desired relative position. If the desired relative position is present, one of the support elements automatically compensates for the distance, so that the alignment element then has to compensate for a smaller or no distance deviation.

This is particularly advantageous following the installation of the sash on a frame immediately following its installation in the building opening, since the otherwise necessary adjustment work is dispensed with. The adjustment work is completed when the sash is attached and closed for the first time.

Fig. 1 shows a section of an open sash 1, which is connected to the frame 3 via a hinge 2. The hinge 2 is attached to a rebate surface 4 of the sash 1 with a flange 5 and engages with an angled support arm 6 in a pocket 7 of a trough-like recess of a frame-side bearing block 8. The bearing block 8 is partially received in a recess of the frame rebate 9 and lies with it Flanges 10, 11 on the frame rebate 9. Corresponding fastening elements in the form of screws 12 are also provided here.

As evidenced by the Fig. 3 it can be seen that the bearing block 8 has a guide contour 14 for guiding the free end 13 of the support arm 6. In the exemplary embodiment, the guide contour 14 is designed as a semicircular link 15 which forms an inner semicylindrical sleeve 16. The sleeve 16 is penetrated by fastening screws 17 which end in an approximately quarter-circular abutment 18. The fastening screws 17 reach through an elongated hole recess 19 in the sleeve 16. The alignment of the elongated hole recess 19 increases in the closing direction, so that the wing 1 is raised slightly when it is closed. This also applies to the bottom of the guide contour 14. For this purpose, the height of the support arm 6 and the corresponding height of the pocket 7 are matched accordingly.

In addition, the support arm 6 and the bearing block 8 are connected to one another via a relief device 20. This consists of a pull rope 31 which is fastened on the one hand to the support arm 6 and on the other end to the bearing block 8. While the end 21 facing the support arm 6 forms a T-toggle 22 which can be hung on the support arm 6, the end 23 is assigned to an actuating device 24. This adjusting device 24 is assigned to the bearing block 8 and, as evidenced by the Fig. 2 from a first wedge 25 and a guide 26 receiving it. A wedge-shaped base 27 or a wedge attached to the base is assigned to the wedge 25, so that wedge surfaces 28, 29 are opposite one another. The bottom and the wedge surface 28 are provided with a slot through which the pull rope 31 passes. The wedge surfaces 28, 29 are provided with complementary locking strips 32, 33 which have an inclined edge on one side and an opposite, almost parallel edge. This creates a tooth system that can slide past one another in one direction, but is blocked in the opposite direction. The width 134 of the wedge 25 is dimensioned such that it can be displaced horizontally in the guide 26. A strong energy storage device in the form of a compression spring 34 acts on the wedge 25 and tries to move it along the wedge surface 28.

The function of the ligament is obvious. A pivoting movement of the wing 1 leads to a displacement of the support arm 6 in the guide contour 14. This guides the support arm 6 in a circular arc contour which forms the axis of rotation. The abutment 18 and the Fastening screws 17 hold the wing 1 or the support arm 6. The weight forces to be absorbed by the hinge 2 are first transferred to the horizontal surfaces of the guide contour 14. The inclined configuration of the elongated hole recesses 19 described above leads to the fact that the wing 1 is raised against gravity when the wing is closed. The relief device 20 is thus free of force, so that the normal force acting on the wedge surface decreases or disappears. With a low normal force, the compression spring 34 can move the wedge 25 laterally and the locking strips 32, 33 slide past one another. As a result, the wedge 25 is displaced vertically upwards and tensions the pull cable 31. If this is tensioned, locking strips 32, 33 come one behind the other. The pull rope 31 can now not absorb any weight forces; these are still absorbed by the guide contour 14. If, however, the wing 1 is opened again, the guide contour 14, which slopes down in the opening direction, causes the wing 1 to be lowered. The previously relaxed tension rope 31 is thereby tensioned. and takes the weight of the sash. This takes place advantageously when the support arm 6 is seated with only a small area in the guide contour 14, that is, with a steadily decreasing contact surface of the support arm 6 in the guide contour 14, there is an increasing load-bearing portion of the relief device 20. The next time the sash is closed Therefore, only as the closing angle progresses does the weight forces dissipate via the support arm 6 and the guide contour 14. The guide contour 14 is therefore primarily loaded by the radial forces occurring during the formation of the axis of rotation. The above-described arrangement contributes to the fact that the pull rope 31 comes into an approximately tangential alignment with respect to the guide contour 14 when the wing 1 is open, such as Fig. 3 indicates. In this position, forces that arise perpendicular to the frame plane are also absorbed via the pull rope 31. That in the Figs. 1 to 3 The illustrated hinge 2 is a middle of three along the hinge axis formed by this. In particular, the middle of the three hinges can hardly be adjusted to be load-bearing.

The actuating device 24 can also be designed in accordance with the exemplary embodiment described below with an identical configuration of the hinge 2. For this purpose, it is provided that the guide 26 is designed as a cylinder in which a piston corresponding to the wedge 25 is guided. The piston seals the guide in an intermediate space and a supply and is at the same time supported against the guide base by a strong compression spring that acts as a spreading spring. As a result, the pull rope 31 is tensioned. The piston has a valve through which a pressure-resistant medium can flow from a supply into the cylinder. The valve is permeable in one direction and closes when the medium in the space has an increased pressure. If the volume of media in the space between the cylinder and piston is smaller than the available volume, the valve lets the media out Flow from the supply into the space in between. This increases the volume of the space and the pull rope remains taut.

In the case of the Figures 4 and 5 The pivot hinge arrangement shown is formed by a pivot pin 35. The pivot pin 35 engages in a hinge sleeve 36 for this purpose. The hinge sleeve 36 is a cylindrically shaped section of a sheet metal section, to which an angled cantilever arm 37 adjoins the hinge sleeve 36. Its leg 38, which runs parallel to the frame rebate 9, is connected to a fitting bracket 39 which is attached to the rebate surface 4 of the sash 1. The fitting bracket 39 engages around a wing corner 40. The pivot pin 35 engaging in the hinge sleeve 36 consists in turn of a sleeve 41; in this a piston 42 is slidably received. A liquid medium 47 is available above and below the piston 42. A compression spring 43, which is supported on a plug 44 on the underside, is arranged below the piston 42. A valve 45 is arranged in the piston 42. The valve 45 is designed in such a way that it closes tightly when there is pressure in the space 46 between the plug 44 and piston 42, but opens when there is no pressure in the space 46 and the medium 47 can flow in from the reservoir 48 into the space 46.

The piston 42 is provided on the top with a piston rod 49 which protrudes through a sealing closure 50 over the sleeve 41. At the protruding end, the piston rod 49 carries a spherical cap 51. This supports a pressure piece 52 which is axially fixed in the hinge sleeve 36. This can take place in that the sheet metal strip for forming the hinge sleeve 36 is narrowed at the edge 53 by means of an inwardly shaped radial deformation of the hinge sleeve 36.

A pivot lever 54 is mounted pivotably about an axis 55 on the leg 38. The pivot lever 54 is therefore between the leg 38 and the frame fold 9. A spring 56 is arranged as a compression spring so that one end 57 the pivot lever 54 in the Fig. 5 seeks to pan clockwise. A finger 58 is provided to rest against a stop 59 on the pivot lever 54.

Finally, a coupling extension 30 is provided on the plug 44, which is pivotably assigned to a bolt in order to form a horizontal tilting axis.

The following function results from the arrangement. If the wing 1 is closed, the finger 58 of the pivoting lever 54, which is swung out in the direction of the frame 3 of the rebate surface 4 by the spring load, hits the stop 59. This occurs even at a small closing angle, since the pivoting lever 54 is due to its small Distance to The axis of rotation reaches the frame 3 very early. The pivot lever 54 is supported on the stop 59 and sets the desired seam spacing. If the distance between the hinge sleeve 36 relative to the frame rebate 9 is greater than that resulting from the support of the hinge sleeve 36 on the pivot pin 35 with the dome 51 and the pressure piece 52, the pressure piece 52 lifts off the dome 51. The pivot pin 35 only has to absorb radial forces. The piston 42 is accordingly free of force and can be moved upwards by the compression spring 43. In this case, the pressure-resistant medium 47 will flow from a supply 48 into the intermediate space 46 through the opening of the valve 45, since the media volume in the intermediate space 46 is less than the available volume. When sufficient medium has reached the intermediate space 46 from the supply 48, the spherical cap 51 abuts the pressure piece 52. The valve 45 closes due to the pressure equalization and its spring loading. At the same time, the wing 1 is always supported in the closed position by the device consisting of the pivot lever 54 and the stop 59, so that the piston 42 remains free of pressure.

It has been shown in practice that if the alignment element is the pivot lever 54, which is pivoted in the open position of the sash 1 in the direction of the frame 3 and is supported on a stationary frame stop 59 when the sash 1 is closed, the effective length of the pivot lever is maximized should be. To avoid additional components, the stop 59 can be part of the frame-side bearing block or it can be attached as a separate component.

the Fig. 6 shows a further embodiment based on the embodiment according to a pivot pin 35 Figures 4 and 5 . The hinge arrangement here also comprises a hinge sleeve 36 as in FIG Figures 4 and 5 shown. In this in the Fig. 6 Hinge sleeve 36, not shown, engages pivot pin 35. The pivot pin 35 is made in several parts according to this exemplary embodiment and consists of a support part 60, a sleeve 61, a compression spring 62, a support wedge 63 and a pressure piece 64 . The sleeve 61 rests on the collar 66. A holding section 67 with a rectangular cross section is closely matched to the inner dimensions of the sleeve 61. A narrow rectangular connecting section 68 leaves space in the sleeve 61 for the arrangement of the compression spring 62. This is followed by a wedge 69. The support wedge 63 is assigned to this in the sleeve 61 along its wedge surface 70. With a horizontally extending support surface 71, the support wedge 63 engages under the pressure piece 64. The support wedge 63 is also manufactured as a stamped part from a sheet metal section. So that the wedge surfaces 70, 72 of the wedge 69 and the support wedge 63 remain in their position, the pressure piece 64 engages with two prongs around the support wedge 63 and the wedge 69. This prevents the support wedge 63 from tilting, which would otherwise be in the sleeve 61 without a guide . The support wedge 63 and the wedge 69 form two sliding pieces that can be axially displaced relative to one another, while the pressure piece 64 is mounted in the sleeve 61 so as to be axially displaceable. The wedge surfaces 70, 72 are, like the enlarged illustration Fig. 7 shows, provided with teeth 73, 74 engaging behind one another. The design of the teeth is such that a force acting in the perpendicular 75 causes a force component on the teeth 73, 74 which reinforces the engagement of the teeth 73, 74. For this purpose, the transverse toothed edges 76, 77 are inclined with respect to a horizontal line 78 and are shaped sloping in the direction of a main line 79.

The interaction with the Figures 4 and 5 The known wing hinge is as follows: The hinge pin 35 engages in the hinge sleeve 36 and supports it with the pressure piece 64 on the pressure piece 52. If the wing 1 is closed, the pivot lever 54 arrives, as already explained above; for abutment against the stop 59. This results in a relative alignment of the hinge sleeve 36 with respect to the frame 3 and the frame bearing block fixedly mounted thereon. If necessary, the pivot lever 54 lifts the hinge sleeve 36 so that the pressure piece 52 is lifted off the pressure piece 64. The pressure piece 64, which is now weight-free as a result, is under the force of the compression spring 62 via the support wedge 63 and moves upwards in the sleeve 61. The wedge surfaces 70, 72 slide past one another until suitable toothed edges 76, 77 are opposite one another. In order to support the engagement of the teeth 73, 74, a flat spring formed in one piece with the pressure piece 64 is effective on the rear side of the support wedge 63, at least in some areas. This flat spring promotes the meshing of the teeth 73, 74.
