FIELD OF THE INVENTION

The invention relates to a two-part hinge device and a method for adjusting the two-part hinge device, and a use of the hinge device according to the independent claims.

BACKGROUND OF THE INVENTION

EP 0962616 B1 discloses a two-part door hinge consisting of two housings which is designed for heavy or wide doors. An adjustment, i.e. a adjustment of the door relative to the door frame is effected by manipulation of the door hinge, by means of eccentric bearing bushings or eccentric bolts. The weight of the door is also brought to bear on the bolts by a pressure plate. EP 0 271 053 A2 discloses a two-part hinge of the same kind for a door or for a window consisting of two housing parts.

The disadvantage of this known solution is that adjusting the door is labour-intensive and not in any way intuitive. Moreover, the construction of the door hinge is complex, and consequently expensive. In particular, the shaping of the eccentric bolt is difficult.

SUMMARY OF THE INVENTION

It is an object of the present invention to resolve one or more drawbacks of the related art. In particular, the objective is to create a two-part hinge device for a door, a gate or a window which enables the door or window to be aligned relative to the frame intuitively, quickly, and consequently economically. It is further intended to provide a method by which intuitive, quick and consequently economical alignment of the door or window relative to the frame is enabled. In addition, the hinge device should be used in such manner that the number of motion cycles with the hinge device is increased.

This object is solved with the apparatus and the method as well as the use defined in the independent claims. Advantageous further developments are described in the figures and the dependent claims.

A two-part hinge device according to the invention for a door, a gate or a window, comprising a first housing part and a second housing part, which in the assembled state form a hinge housing, a rod that extends inside the first housing part and the second housing part along the axial direction thereof, wherein the rod has at least three successive—a first, a second and a third—rod sections. The first rod section is supported in the first housing part by a clamping element and the third rod section supports the second housing part. In the region of the second rod section, the rod is adjustable relative to the first housing part in two directions at an angle to each other and independently of each other, and the two directions extend at an angle to each other transversely to the axial direction of the rod.

Because of its special adjustment capability, the two-part hinge device can be adjusted particularly easily and with a few hand movements by just one person/one fitter without assistance in such a way that the door or window which is fitted on the hinge device can be opened and closed without resistance and reproducibly hundreds of thousands of times. This has the effect of considerably simplifying the installation conditions for a fitter on a construction site or in a workshop, and results in substantial cost savings, since any maintenance of the two-part door hinge can also be carried out by a caretaker or untrained person (with no technical qualification). The rod may be introduced into a first housing opening in the first housing part. The second housing part is in operative connection with the rod, in that it supports the second housing part, as described previously. On the other hand, the third rod section may be introduced into a second housing opening of the second housing part, so that the second housing part is supported in the second housing opening simply and rotatably with respect to the first housing part.

The first housing part and/or the second housing part advantageously contain(s) at least one adjuster for adjusting for height adjustment in extension of the rod. The adjuster for height adjustment is arranged in one of the two housing parts, so that height adjustment is carried out with just a single adjustment mechanism. Alternatively, one adjuster for height adjustment may be provided in each of the two housing parts, so that both housing parts may easily be adjusted relative to each other. The at least one adjuster is in operative connection with the rod, so that is may be used to adjust the distance between the first housing part and the second housing part based on the movement of the rod inside the hinge housing.

In particular, the first housing part and/or the second housing part is/are designed in the shape of droplets and have a flat fastening section for the door plates or door frame plates. Consequently, the hinge device can be fastened to the door or door frame more easily and more firmly.

Alternatively, other positioning elements such as screws, pins, bolts or the like are suitable. The rod is adjustable relative to the first housing part in two directions at an angle to each other and independently of each other within a defined range, that of the second rod section, with the result that the two-part hinge device can be adjusted in two spatial directions intuitively and easily, using just the rod. Consequently, it is not necessary to engage a technically trained fitter at the construction site to adjust the two-part hinge device. The respective spindles may be secured in the rod with the aid of chemical securing means, by using Tuflok® or Nytemp® as chemical locking means, for example. Chemical securing means for spindles have a powerful locking effect even at high temperatures.

The rod is preferably embodied as a suspension rod or as a bolt. A bolt has a cylindrical surface, for example, which enables it to be inserted simply and symmetrically in the respective openings of the first housing part and of the second housing part, allowing said housing parts to rotate easily about the axial direction of the rod. A suspension rod is a rod with a movable bearing, which is supported in the hinge housing by at least one point and consequently supports the second housing part efficiently, so that the two-part hinge device can be adjusted easily at least about this point.

The suspension rod preferably has at least one polygonal section on the second rod section. The polygonal section, a solid rectangular section for example, has at least one polygonal cross-section, which is formed symmetrically about the axial direction of the rod. The rod is adjusted relative to the first housing part at the second rod section, wherein the polygonal section comprises a positioning element, for example a screw. This positioning element holds the rod firmly in position and enables the rod to be adjusted relative to one of the housing parts. Alternatively, the second rod section of the suspension rod has a spherical section or a cylindrical section, wherein the respective section comprises at least one positioning element, as described here, so that the suspension rod can easily be inserted in the first housing part and adjusted therein. Alternatively, the second rod section of the suspension rod has a section which has a larger cross-section than the first rod section. Suspension rods of such kind are simple to manufacture and mechanically strong.

The suspension rod advantageously has at least one cylindrical section as the first rod section. The cylindrical section has a cylindrical surface which is formed symmetrically about the axial direction of the rod. The second housing part can easily be rotated about the first rod section, which is designed as a cylindrical section.

The first rod section of the suspension rod advantageously has a polygonal section. The polygonal section on the first rod section of the suspension rod may serve as an antirotation device to prevent the suspension rod from rotating about the axial direction in the first housing part.

The suspension rod advantageously has at least two erosion notches over its longitudinal extension. This lends the suspension rod a bone-like profile, enabling an economy of material and improving the ratio of mass to rigidity. The at least two erosion notches extend at least partly into the first and third rod sections as well as along the entire second rod section, enabling maximum economy of material.

The rod is preferably constructed as a single part. A single-part rod can be produced simply and has intrinsically high mechanical strength, so that any wear or deformation of the rod during use of the hinge device is reduced.

The rod is preferably of two-part construction, wherein the rod consists of a first rod element and a second rod element. Two-part rods enable simpler production, in particular if the formations and/or the materials of the two rod elements are of different designs. The two rod elements have connecting sections, with which the two rod elements can be connected to a rod mechanically, by screwing, for example. The tilt angle in a two-part rod can also be compensated easily, so that the hinge of the door, window or gate remains movable and consequently the hinge can be prevented from canting.

The first rod section is advantageously arranged on the first rod element, and the third rod section is arranged on the second rod element, wherein the second rod includes the first and second rod elements. In this way, the rod can be clamped to the first rod element in the first housing part. Additionally, the second housing part is in a bearing force-operative connection with the second rod element, which enables it to rotate easily and largely without backlash. The adjustment of the rod at both rod elements as described here results in greater flexibility when adjusting the hinge device.

The second rod element preferably comprises a bushing for introducing the force from the second housing part, at least a part of the second rod section being arranged on the bushing. In this configuration, the bushing is arranged immovably on the second rod element and arranged non-rotatably in the axial direction of the rod, and thus also forms and additional part of the rod. The bushing typically consists of a material that is different from the first rod element, in particular a material with a stronger wear and/or mechanical strength behaviour than the first rod element. With the suitable material pairing, the service life of the hinge device is prolonged decisively, because the tribological properties of the two-part hinge device can be optimised.

The suspension rod is advantageously a triaxial ellipsoid. This has the effect of improving the distribution of the load peaks on neuralgic sections of the suspension rod, in particular the second rod section, during use of the hinge device, since the load peaks at these sections are absorbed by a greater quantity of material. Moreover, the first rod section and the second rod section have lower material thickness, and consequently at least the first rod section can be inserted in the bushing easily and the outer diameter of the bushing is reduced. A hinge device with a suspension rod of such kind enables its use for window, gate or door systems according to DIN EN1935:2002 for load cases with a door weight up to 350 kg, for example.

The rod is preferably adjustable in the region of the second rod section by means of positioning elements, which are advantageously spindles. The positioning elements effect a reproducible adjustment of the rod in the directions at an angle to each other. At the same time, a positioning element may be present for each of the two directions at an angle to each other. Spindles may be embodied as screws, such as grub screws, for example, arranged movably along a longitudinal extension of a threaded hole in the second section of the rod. The spindles can be adjusted easily and independently of each other to adjust the rod inside the hinge housing. For this purpose, the second rod section has at least two threaded holes, which extend along said second rod section in directions at an angle to each other and are offset along the axial direction.

The at least two erosion notches on the second rod section advantageously each have a flat area. This makes it easy to insert the positioning elements in the threaded hole, thereby simplifying adjustment of the hinge device.

The rod is preferably secured against undesirable rotation about the axial direction with an antirotation device. This enables the rod to be held non-rotatably in the hinge housing. A polygonal plate, preferably rectangular or octagonal in shape, for example, may serve as the antirotation device and may be embodied as a locking ring. The locking ring, for example a circlip, may be used as a pull-out guard, so that intentional removal of the rod from the hinge housing may be prevented.

The first rod section of the suspension rod advantageously includes a polygonal section. The polygonal section on the first rod section of the suspension rod may serve as an antirotation device, to hold the suspension rod non-rotatably about the axial direction in the first housing part.

The rod is clamped, preferably in the radial direction and advantageously in the axial direction with respect to the first housing part, at the first rod section. In this way, the rod is held immovably in the first housing part at the first rod section, which in turn simplifies alignment of the second housing part and therewith of the door or window with the frame during fitting.

Preferably, at least a first adjustment opening and a further adjustment opening are provided. In this way, the positioning elements are easily accessible, allowing simple adjustment of the rod relative to the first housing part. The first adjustment opening and the further adjustment openings are preferably arranged in two directions offset at an angle to each other.

The first section of the rod preferably has a ball head which fits the clamping element precisely, wherein the clamping element encloses a hollow spherical bearing. In this way, the rod is clamped at a single point inside the hollow spherical bearing and so also inside the first housing part, so that it can be effectively adjusted about this point inside the hollow spherical bearing.

The precisely fitting ball head advantageously has radially arranged polygonal surfaces, wherein a prism-shaped plate is arranged on the hollow spherical bearing. This has the effect of improving load distribution in the first housing part and implementing an antirotation device.

The precisely fitting ball head advantageously has radially arranged polygonal surfaces which engage in a polygonal bearing, for example a prism-shaped bearing. This creates an effective antirotation device while at the same time reducing the number of components.

An antirotation device is advantageously arranged in the ball head to hold the rod non-rotatably about the axial direction inside the first housing part. In this context, the antirotation device may be embodied as a first bolt, at least a portion of which extends through the ball head a portion of which protrudes from the ball head. The protruding portion of the first bolt is in an operative connection with the first housing part, for example in a slotted hole or a groove in the first housing part, so that the rod is held non-rotatably. The first bolt may also function as a pull-out guard, so that it is possible to prevent the rod from being removed from the first housing part inadvertently.

The first bolt is advantageously arranged parallel to at least one of the two directions at an angle to each other, transversely to the axial direction of the rod. This has the effect of providing a pull-out guard that can be produced easily.

Alternatively to this, the first section of the rod includes a polygon head which fits the clamping element precisely, wherein the clamping element encloses a polygonal bearing. Thus, the rod is clamped on multiple sides inside the polygonal bearing and therewith also inside the first housing part, so that the rod is held securely. The polygon head may function as an antirotation device, to hold the rod non-rotatably about the axial direction inside the first housing part.

The rod may preferably be adjusted by means of at least four spindles, wherein one spindle is arranged in each of the first rod section and the third rod section, which have two directions at an angle to each other, and wherein two spindles are arranged in the second rod section, wherein the first spindle in the second rod section is aligned parallel to the spindle of the first rod section, and the second spindle in the second rod section is arranged parallel to the spindle in the third rod section. This enables the rod to be adjusted in such manner that the first housing part is adjustable only in a first spatial direction and the second housing part is adjustable only in another spatial direction. Consequently, adjusting the hinge device is simple, and one person alone is needed, for example a fitter or an individual without specialist training.

In an alternative embodiment of the two-part hinge device according to the invention, the rod is adjustable by means of at least four spindles, wherein one spindle is arranged in each of the first rod section and the third rod section, which have two directions at an angle to each other, and wherein two spindles are arranged in the second rod section, the first spindle in the second rod section being aligned perpendicularly to the spindle of the first rod section, and the second spindle in the second rod section being aligned perpendicularly to the spindle of the third rod section. In this way, the rod is adjustable in such manner that each of the housing parts is adjustable not only in a first spatial direction but also in a further spatial direction. This has the effect of making adjustment of the hinge device more flexible, wherein only one person, for example a fitter, is needed.

The third rod section is preferably embodied as a ball-head bolt, on which the bushing is supported. A ball-head bolt has a spherical end element on the frontal face of rod, the diameter of which may be larger than the diameter of the rod, for example the first rod section. The spherical end element may easily be positioned in the bushing.

Advantageously, an antirotation device is arranged in the ball-head bolt to hold the rod non-rotatably about the axial direction inside the second housing. In this configuration, the antirotation device may be embodied as a second bolt, at least a portion of which extends through the ball-head bolt and a portion of which protrudes from the ball-head bolt. The protruding portion of the second bolt is in an operative connection with the second housing part, so that the rod is held non-rotatably. The second bolt may also function as a pull-out guard, so that it is possible to prevent the rod from being removed from the second housing part inadvertently.

The second bolt is advantageously arranged parallel to at least one of the two directions at an angle to each other, transversely to the axial direction of the rod. This has the effect of providing a pull-out guard that can be produced easily.

Alternatively or additionally, the ball-head bolt comprises bevels for forming an antirotation device, sod that the rod can be fixed non-rotatably about the axial direction inside the second housing part. Alternatively, the ball-head bolt has polygonal surfaces for forming an antirotation device, so that the rod may be held non-rotatably about the axial direction inside the second housing part.

An axial bearing is advantageously introduced between the second housing part and the bushing, thereby creating a simple axial bearing for the rod.

The axial bearing is advantageously arranged in force-fitting manner inside a housing part so that it is held securely in the hinge device.

Alternatively, the axial bearing includes a shoulder and is arranged in the second housing part in form-fitting manner with the aid of a locking means to prevent undesirable shifting in the hinge device.

A method according to the invention for adjusting a hinge device for a door or window, in particular a two-part hinge device for a door, gate or window as described here, wherein a rod is present in the hinge device, which rod comprises at least three rod sections, includes at least the following steps:

Joining a first housing part to a second housing part to form a door hinge housing, wherein a first rod section is arranged inside the first housing part and at least a portion of the third section of the rod is at least partly introduced into an opening in the second housing part;Adjusting the first housing part relative to the second housing part, wherein the distance between the housing parts is altered thereby;Adjusting the rod perpendicularly to the axial direction, wherein the adjustment takes place in a second section of the rod, which is arranged between the first rod section and the third rod section, and wherein the rod is adjusted in two directions at an angle to each other and independently of one another.

This method enables intuitive, rapid and consequently economical alignment of the door or window relative to the frame.

The adjustment of the rod in the second rod section is preferably caused by actuating at least two positioning elements.

A use according to the invention of the two-part hinge device described herein is realised when the first housing part is arranged on a pivotable door or gate or window frame or door leaf and the second housing part on an immovable door or gate or window frame.

In such an arrangement, the first section of the rod is supported in the first housing part by the clamping element, and the third section of the rod is supported in the second housing part, with the result that the load in the two-part hinge device is very much more favourable. In this way, the two-part hinge device is producible less expensively and with smaller dimensions, and the number of motion cycles it can perform is increased. When the door or gate or window frame or the door leaf is swung, the rod is only exposed to a static load from the door, the gate or the window, regardless of the opening angle of the door, gate or window.

Further advantages, features and particularities of the invention will be discerned from the following description, in which exemplary embodiments of the invention are described with reference to the drawing.

In the region of the second rod section17, the rod15is adjustable relative to the first housing part20in two directions X, Y which are at an angle β to each other, wherein the two directions X, Y at an angle β to each other are arranged transversely to the axial direction60of the rod15. The rod15is also adjustable in direction X, and in direction Y independently thereof. The two-part hinge device11comprises positioning elements for adjusting the rod15. The positioning elements shown are spindles22and32, each of which has a thread and may be screwed into two threaded holes19,19ain order to adjust the rod15. For this purpose, the inner sides of the threaded holes19,19aare furnished with corresponding threads. The two threaded holes19,19aextend in two directions X, Y at angle β to each other in the second rod section17. The rod15is clamped in the radial direction with respect to the first housing part20at the first rod section16.

The first housing part20has a first adjustment opening23and a second adjustment opening24, which are arranged in two directions X, Y that are offset with respect to one another by angle β. In the assembled state, the rod15of the two-part hinge device11can be adjusted by means of the spindles22and32and with a tool, wherein the tool is inserted in the respective adjustment opening23,24to turn or actuate the spindles22,32(not shown). Alternatively, other positioning elements are suitable, for example screws, pins, bolts and the like.

FIG.2shows the single-part rod15, which is embodied as a suspension rod, wherein the suspension rod has at least one polygonal section17aon the second rod section17. The polygonal section17ahas at least one polygonal cross-section, which is designed symmetrically about the axial direction60of the rod15. Adjustment of the rod15is effected at the second rod section17, wherein the polygonal section17ahas surfaces in which the threaded holes19,19aare arranged.

When the adjustment member41is actuated with a tool (not shown), the adjustment member41is turned into the threaded adjustment hole43and presses against the axial bearing45, and thus also against the bushing25, with the result that the two housing parts20,30are adjustable relative to each other in order to adjust the height of the door or window relative to the frame. The adjuster40is in operative connection with the rod15, and consequently the distance between the first housing part20and the second housing part30is adjustable as a function of the motion of the movement of the rod15in the hinge housing12. The threaded adjustment hole43is closable with a cover42, which in the closed state presses on the adjustment member41, so that the adjustment member41is fixed in place, because it is locked with the cover42.
