Description

The invention relates to a hinge assembly according to the preamble of claim 1. Such hinge bands have already become known in various embodiments. That's how it shows WO 2011/006 682 A1 a band for pivotally mounting a wing on a frame. This hinge assembly has two mutually pivotable hinge parts which are pivotable relative to each other about a common pivot axis. The pivot axis is formed by a housing and an intervening swivel bracket. The swivel bracket is a curved link follower which engages in a guide slot of the housing. Guide slot and swivel bracket are arcuately matched and are the means for forming the pivot axis. The relative assignment of housing and swivel bracket can not be adjusted. There is only a horizontal adjustment over interposable spacer plates provided. Therefore, if the wing sags, no correction can be made.

For this purpose, the EP 2 245 251 B1 in that the hinge pin has a sleeve into which an inner bolt with flat rectangular cross-section engages. The bolt sleeve can be adjusted relative to the inner bolt via a screw member, so that the effective axial length of the hinge pin is adjustable. The disadvantage here is that despite the large number of components used a manual adjustment must be made, which is also often difficult to access in a built-frame through the soffit of the window opening.

From the DE 10 2007 024 742 A1 a window or door has become known in which a wing is articulated to the frame via a hinge and a carrying device. The joint can absorb only small vertical forces due to its structure, so that the additional support device to compensate for the weight forces of the wing. For this purpose, the support device is designed as a displaceably mounted in the frame arm, which is rotatably associated with the wing and is led out of its frame-side storage when opening the wing. As a result, the support arm with complete rotation opening only a small support surface in the frame-side guide, which also penetrates deep into the frame material and thereby greatly reduces the frame cross-section, while the carrying capacity is limited due to the large lever.

To ensure the relative position of fittings is already out of the EP 0 515 931 B2 known, a pivotally mounted on the wing support arm so with a spring force act on its free end projecting in the direction of the frame and when closing the wing meets a frame-side stop, and it is supported when closing the wing, so that the rotary axis distal end of the wing can be raised in the frame. In connection with it it is through the EP 0 875 651 B1 also already known to compensate for the horizontal position of the pivot axis of a hinge assembly independently. The above-described measures serve to align the sunk-down wing side remote down, with the aim of enabling a closing of the wing. If it comes with time to a setting on the hinge axis side, then the measures described are ineffective.

The object of the invention is therefore to provide a generic hinge assembly which avoids the disadvantages of the prior art and combines high carrying capacity with improved adjustment.

To achieve this object, an alignment element is provided, which brings about a functional axial alignment of the joint parts and that at least one of the support elements automatically compensates for a distance caused by the alignment element of the support elements.

The alignment element essentially serves the relative orientation of the hinge strap constituent components of the hinge. 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 causes an independent compensation of the distance, so that the alignment element subsequently has to compensate for a smaller or no distance deviation.

This is particularly advantageous following the installation of the wing on a frame immediately following its installation in the building opening, since the otherwise necessary adjustments omitted. With the hanging of the wing and its first closing the adjustments are completed.

A further development provides that the first joint part consists of a frame-side bearing block, which has a guide contour for a guided therein, according to the pivot axis shaped support arm of a wing bearing part. This arrangement results in a concealed arrangement with the wing closed arrangement of the hinge assembly.

In order to increase the carrying capacity of the hinge assembly is provided that between the bearing block and the wing bearing part a relief device is effective.

The embodiment described above can be characterized by the fact that the alignment is formed by the inclined in the closing direction relative to a horizontal rising guide contour, simplify. The already required active surfaces cause the same when lifting the wing lifting.

To simplify the construction it is provided that the relief device is a cable which is effective between the bearing block and the wing bearing part.

An easily manufactured embodiment provides that the support elements provide two wedge surfaces, which are mutually displaceable horizontally.

An alternative embodiment provides that the support elements consist of a cylinder and a piston guided therein, and between piston and cylinder, a spreading spring is effective and a valve can flow a pressure-resistant medium from a supply in the cylinder when the volume of media between the cylinder and piston less than the available volume. This embodiment is also suitable for large forces and can be reconciled with the requirements for small space.

A simple and practical arrangement provides that the alignment is a pivot lever which is swung in the open position of the wing in the direction of the frame and is supported when closing the wing to a stationary frame stop.

In order to be used with existing hinge straps is provided that the support elements consist of a pivot pin and a thrust piece resting thereon, wherein the pivot pin consists of two axially displaceable sliding members, which are assigned to each other on wedge surfaces which are provided with engaging behind serrations.

To find use in existing sash bands can also be provided that the first hinge part is a hinge sleeve in which a hinge pin is received, which supports the hinge sleeve against the frame and which is formed of a sleeve which receives a piston slidably, the together forms with a stopper a gap with a medium and which rests on a piston rod with a support surface on the hinge sleeve, and between the plug and piston, a compression spring is effective and the piston supports a valve through which the medium can flow from a supply in the intermediate space ,

For this embodiment, it can also be provided that the alignment element is a stop acting on the hinge sleeve.

In order to simplify the construction and assembly, it is provided that the abutment is a pivoting lever mounted on a cantilever arm of the hinge sleeve and projecting in the direction of the frame in a force-loaded manner.

In order to ensure the pivotability of the support elements relative to each other and to allow the assembly in any position is provided that the support surface is a convex shaped and projecting over the sleeve dome.

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

Evidently the Fig. 3 It can be seen that the bearing block 8 for guiding the free end 13 of the support arm 6 has a guide contour 14. The guide contour 14 is executed in the embodiment as a half-circle gate 15, which is an inner semi-cylindrical Sleeve 16 forms. The sleeve 16 is penetrated by fastening screws 17 which end in an approximately quarter-circular abutment 18. The alignment of the slot recess may be horizontal, but is preferably increasing in the closing direction, so that the wing 1 is slightly raised when closing. 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 bag 7 is adjusted accordingly.

In addition, support arm 6 and bearing block 8 are connected to one another via a relief device 20. This consists of a pull rope 31, which is attached on the one hand to the support arm 6 and the other end to the bearing block 8. While the support arm 6 facing the end 21 forms a T-knob 22 which can be hooked to the support arm 6, the end 23 of an adjusting device 24 is assigned. This adjusting device 24 is assigned to the bearing block 8 and is evidently the Fig. 2 from a first wedge 25 and a guide 26 receiving this wedge 25 is associated with a wedge-shaped bottom 27 or attached to the floor wedge, so that wedge surfaces 28, 29 are opposite. The bottom and the wedge surface 28 are provided with a slot which is penetrated by the pull cable 31. The wedge surfaces 28, 29 are provided with complementary locking strips 32, 33, which have on one side an inclined and an opposite almost parallel edge. This creates a toothing that can slide past one another in one direction, but is locked 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 force 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 hinge is obvious. A pivoting movement of the wing 1 leads to a displacement of the support arm 6 in the guide contour 14. This leads 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 and the support arm 6, respectively. The weight forces to be absorbed by the hinge 2 are first transferred to the horizontal surfaces of the guide contour 14. The above-described inclined configuration of the elongated slot recesses 19 results in a closing of the wing to the fact that the wing 1 is lifted against gravity. The relief device 20 is thereby force-free, so that the force acting on the wedge surface normal force decreases or disappears. At a low normal force, the compression spring 34 can move the wedge 25 laterally and the locking strips 32, 33 slide past each other. As a result, the wedge 25 is displaced vertically upward and tensions the traction cable 31. If this is tensioned, locking strips 32, 33 come one behind the other. The traction cable 31 can now absorb any weight forces, these are still taken up by the guide contour 14. Will however the Wing 1 opened again, the sloping in the opening direction guide contour 14 causes the wing 1 is lowered. The previously tensioned pull cable 31 is thereby tensioned. and picks up the sash weight. This is advantageously carried out when the support arm 6 is seated with only a small surface in the guide contour 14, ie, with steadily decreasing contact surface of the support arm 6 in the guide contour 14, there is an increasing support portion of the discharge device 20. The next closing of the wing Therefore, it comes only with progressive closing angle to a removal of the weight forces on the support arm 6 and the guide contour 14. The guide contour 14 is therefore primarily charged by the radial forces occurring in the formation of the axis of rotation. The above-described arrangement contributes to the pulling cable 31 coming into an approximately tangential orientation relative to the guide contour 14 when the wing 1 is open, such as Fig. 3 shows. In this situation, forces that arise perpendicular to the frame plane, also absorbed via the pull cable 31.

That in the Fig. 1 to 3 shown hinge 2 is a middle of three along the hinge axis formed by this. In particular, the middle of the three wristbands can be set hardly stable with manual adjustment.

The adjusting device 24 can also be designed according to the embodiment described below in an identical embodiment of the hinge 2. For this purpose, it is provided that the guide 26 is designed as a cylinder in which a wedge 25 corresponding piston is guided. The piston seals the guide in an intermediate space and a supply and is simultaneously supported with an effective as a spreading spring, strong compression spring against the guide bottom. As a result, the pull cable 31 is tensioned. The piston has a valve through which a pressure-resistant medium from a supply can flow 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 the fluid in the space between cylinder and piston is smaller than the available volume, the valve allows the medium to flow from the reservoir into the gap. This increases the volume of the gap and the pull rope remains taut.

The embodiment corresponds essentially to the exemplary embodiment described in more detail below, with the exception of the design of the axle-forming joint parts.

In the in the 4 and 5 shown hinge assembly, the axis of rotation is formed by a pivot pin 35. The pivot pin 35 engages in a hinge sleeve 36 a. The hinge sleeve 36 is a cylindrically shaped portion of a sheet metal section, an adjoining the hinge sleeve 36 angled Kragarm 37 connects. Whose parallel to the frame rebate 9 extending leg 38 is connected to a fitting angle 39 which is fixed to the rebate surface 4 of the wing 1. In this case, the fitting angle 39 surrounds a wing corner 40. The engaging in the hinge sleeve 36 pivot pin 35 in turn consists of a sleeve 41; in this a piston 42 is slidably received. Above and below the piston 42, a liquid medium 47 is available. Below the piston 42, a compression spring 43 is arranged, which is supported on the underside of a plug 44. In the piston 42, a valve 45 is arranged. The valve 45 is designed so that it closes tightly at pressure in the intermediate space 46 between the plug 44 and piston 42, but opens in the absence of pressure in the intermediate space 46 and the medium 47 can flow from the reservoir 48 into the intermediate space 46.

The piston 42 is provided on the upper side with a piston rod 49 which protrudes a sealing closure 50 through the sleeve 41. At the projecting end, the piston rod 49 carries a cap 51. This supports a pressure piece 52, which is axially fixed in the hinge sleeve 36. This can be done by the sheet metal strip is narrowed to form the hinge sleeve 36 at the edge 53 by means of a, inwardly shaped radial deformation of the hinge sleeve 36.

On the leg 38, a pivot lever 54 is pivotally mounted about an axis 55. The pivot lever 54 is therefore located between the leg 38 and the Rahmenfalz 9. A spring 56 is arranged as a compression spring so that one end 57, the pivot lever 54 in the Fig. 5 looking to pivot in a clockwise direction. A finger 58 is provided for engagement with a stop 59 on the pivot lever 54.

Finally, a coupling extension 30 is provided on the plug 44, which is associated with a pin pivotally to form a horizontal tilting axis.

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

It has been found in practice that when the alignment element of the pivot lever 54 is pivoted in the open position of the wing 1 in the direction of the frame 3 and is supported when closing the wing 1 on a stationary frame stop 59, maximizes the effective length of the pivot lever should be. The stop 59 may be attached to avoid additional components part of the frame-side bearing block or as a separate component.

The Fig. 6 shows by means of a pivot pin 35, a further embodiment based on the embodiment according to 4 and 5 , The hinge assembly also includes here a hinge sleeve 36 as in the 4 and 5 shown. In this in the Fig. 6 not shown hinge sleeve 36 engages the pivot pin 35 a. The pivot pin 35 is executed in several parts according to this embodiment and consists of a support member 60, a sleeve 61, a compression spring 62, a support wedge 63 and a pressure piece 64. The support member 60 is designed as a flat-rectangular sheet metal section and has a bearing eye 65 with a collar 66 , On the collar 66, the sleeve 61 is supported. A holding section 67 having a rectangular cross section is closely fitted to the inner dimension of the sleeve 61. A narrow-rectangular connecting portion 68 leaves in the sleeve 61 space for the arrangement of the compression spring 62. This is followed by a wedge 69 at. This is assigned in the sleeve 61 along its wedge surface 70 of the support wedge 63. With a horizontally extending support surface 71 of the support wedge 63 engages under the pressure piece 64. Also, the support wedge 63 is made as a stamped part of a sheet metal section. In order that the wedge surfaces 70, 72 of the wedge 69 and the support wedge 63 remain in position, the pressure piece 64 with two prongs engages around the support wedge 63 and the wedge 69. This prevents tilting of the support wedge 63, which would otherwise be without guidance in the sleeve 61 , The support wedge 63 and the wedge 69 form two axially displaceable sliding pieces, while the pressure piece 64 is mounted axially verschiebar in the sleeve 61. The wedge surfaces 70, 72 are, as the enlarged view Fig. 7 shows, provided with engaging behind serrations 73, 74. The configuration of the toothings is such that a force acting in the vertical 75 on the toothings 73, 74 causes a force component which reinforces the engagement of the toothing 73, 74. These are the transverse toothing edges 76, 77th inclined towards a horizontal 78 and sloping towards a main line 79.

The interaction with the from the FIGS. 4 and 5 known wing hinge band is as follows: The pivot pin 35 engages in the hinge sleeve 36 and supports it with the pressure piece 64 on the pressure piece 52 from. If the wing 1 is closed, the pivot lever 54, as already explained above; for engagement with the stop 59. The result is a relative orientation of the hinge sleeve 36 relative to the frame 3 and the frame bearing block mounted thereon. As far as necessary, the pivot lever 54 raises the hinge sleeve 36, so that the pressure piece 52 is lifted from the pressure piece 64. The now weight released pressure piece 64 is on the support wedge 63 under the influence of force of the compression spring 62 and moves in the sleeve 61 upwards. The wedge surfaces 70, 72 slide past each other until appropriate toothing edges 76, 77 are opposed. In order to support the engagement of the serrations 73, 74, at the back of the supporting wedge 63, at least in regions, a flat spring formed integrally with the pressure piece 64 is effective, which favors the meshing of the serrations 73, 74.
