Description

I. Field of application

The invention relates to a door hinge or a window hinge with a wing part which can be fastened to a door leaf or to a window sash, a frame part which can be fastened to a door frame or to a window frame, and a pin which is arranged non-rotatably on the wing part or the frame part. The pin may be integrally formed together with this wing part or frame part or be added with its foot part in a corresponding recess of this wing part or frame part. In the former case, the entire pin serves as a supporting part of the pin, in the latter case, the pin projects only with its supporting part from the wing part or frame part carrying it.

The pin projects with its supporting part at least partially into a receiving cavity in the part not provided with the pin. On the pin a bearing attachment is non-rotatably arranged, which thus also at least partially protrudes into the receiving cavity in the mounted state of the door hinge or the window hinge.

Preferably, at least the support part of the pin, in particular the entire pin, has a cylindrical outer contour.

II. Technical background

In the prior art hinges or window hinges are known in which on the journal of the wing or frame part, a bearing attachment is arranged, on which the respective other part is mounted.

Due to the tolerances occurring in the installation of door frames or window frames, by which the door or window frames are out of kiln, it is a common problem that the door leaves or the window sash start to run, that is, to open automatically. Therefore, door hinges or window belts are used, in which by braking means integrated in the band braking elements of a wing part relative to the frame part is opposed to a braking action by which the running of the door or window sash is prevented or reduced.

For example, is from the DE 591 446 a brake hinge with which the friction between the pivot pin and the hinge sleeve is adjustable. This is done by a trained as a double-cone pivot pin whose conical surfaces press against the surfaces of conical recesses in the hinge sleeves and thus trigger a braking effect.

In addition, numerous other versions of door or window hinges are known, with which a braking effect is generated to prevent the running of door or window sashes, for example from the DE 20 2009 015 950 U1 in which a resilient clamping element is arranged on a guide cylinder of the frame part, which is clamped in a receptacle of the wing part, to brake or dampen the movement of the door or window sash.

The disadvantage of these designs is a high level of design and manufacturing complexity and the easing of the braking effect during wear. This makes it necessary to provide adjusting devices by which the wear can be compensated to maintain a sufficient, constant as possible braking effect over the entire period of use of the door. However, the setting leads to a corresponding maintenance and additional design effort for the adjustment.

III. Presentation of the invention a) Technical task

The invention is therefore based on the object to develop a door hinge or a window hinge, in which with little constructive and manufacturing effort a braking effect between the wing part and the frame part is generated, which counteracts a rotational movement of the door leaf or the window sash to the running of the door or the window to prevent. The braking effect should be as independent as possible of assembly tolerances of the door or the window and maintained largely unchanged over the life of the door hinge despite wear without readjustment.

b) Solution of the task

This object is achieved by a door hinge or a window hinge with the features of claim 1. Further features of the invention will become apparent from the dependent claims.

In the case of the door hinge or the window hinge according to the present invention, a pot-shaped or sleeve-shaped bearing attachment, in particular, is placed on the journal of the door hinge. The bearing cap has a peripheral outer surface forming at least a portion of the surface of the bearing cap facing away from the pin. The outer surface of the bearing cap is conical, in particular tapering towards the free end of the pin. The receiving cavity in the wing part or frame part, which is not provided with the pin, has an inner mold surface, the inner mold surface is also conical. In particular, the inner molding surface forms at least part of the surface of the pin. The outer surface of the bearing cap and the inner surface of the receiving cavity face each other.

When the door hinge or the window hinge is mounted, the outer surface of the bearing cap and the inner surface of the receiving cavity are at least partially against each other. In particular, the frame part and the wing part abut each other only on these two surfaces mentioned, and in particular frame part and wing part are not frontally to each other, but in between an axial distance always remains in the operation of the band then on the abutting surfaces then the weight of the door leaf or the sash transferred to the door frame or the window frame. The weight is usually transmitted through 2 or more door or window hinges on the door frame or window frame.

Due to the fact that the outer surface of the bearing cap and the inner surface of the receiving cavity in the assembled state of the door or window strip at least partially abut each other, by the surface pressure between these two surfaces when operating the door hinge or window hinge, so when turning these two surfaces relative to each other, a Generates braking effect, which inhibits a rotational movement of the wing part relative to the frame part or at least attenuates. Due to the braking action between the outer surface of the bearing cap and the inner surface of the receiving cavity running of the door or window sash is prevented. The door or the window either runs much slower than unbraked or persists despite a tolerance-related malposition of the door frame or window frame in their respective position.

The frictional forces required to produce the braking action between the outer molding surface and the inner molding surface result from the weight of the door leaf or the window sash. Due to the conical design of the outer mold surface and the inner mold surface, these surfaces are always at least partially against each other and equal manufacturing tolerances of the components of the door hinge or window hinge. Also set or wear in the door or window hinge is compensated by the conical shaped surfaces, which also in displacements of the wing part in the direction of the frame part continue to rest against each other at least partially, so that an adjustment of the door hinge or window hinge to maintain the braking effect over the life is not required.

According to an advantageous embodiment of the invention, it is provided to arrange an anti-rotation device between the pin and the bearing cap in order to arrange the bearing cap rotatably on the pin. This rotation can be a frictional rotation, a cohesive anti-rotation z. B. by gluing or melting a fusible bearing attachment z. B. of a thermoplastic, or preferably to act a positive rotation. The rotation preventing prevents the bearing cap can rotate on the pin, whereby the transmitted between the inner surface of the receiving cavity cavity and the outer surface of the bearing cup bearing torque is reduced and thus the braking effect between the inner surface and the outer surface molding surface would be reduced or even completely abolished.

In a further advantageous embodiment of the invention with a positive rotation between the bearing cap and pin an internal cavity is formed in the bearing cap. In this, the pin is added, so that the bearing cap sits on the pin and surrounds it at least partially. The inner cavity of the bearing cap and the pin each have a coordinated cross-sectional geometry, which is designed so that a positive engagement between the bearing cap and the pin is. The anti-rotation between the pin and the bearing cap is formed by this positive engagement. This positive connection may be, for example, a square profile, a splined connection, a serration, a polygonal profile or another suitable positive connection.

In a particularly advantageous embodiment of the rotation, a groove is formed on the pin. The bearing attachment has a retaining projection on. The retaining projection engages in the groove when the bearing cap is mounted on the pin. As a result, the bearing attachment is rotationally fixed by a positive connection on the pin. Alternatively, the retaining projection may be arranged on the pin, and the groove in the bearing cap.

In a further advantageous embodiment of the invention, the pin is arranged relative to the wing part or the frame part on which it is arranged on this in the direction of its longitudinal axis movable. Due to the mobility of the pin in the direction of its longitudinal axis relative to the wing part or the frame part, a tolerance compensation of the distance between the wing part and the frame part in the assembled state of the door hinge can be made. This tolerance compensation can be required despite the interaction of the conical inner and outer surface largely tolerance-independent braking torque of a single door or window hinge when the door or the casement is held by several hinges and tolerances cause the individual door or Window bands carry a different proportion of the weight of the door leaf or window sash, so that a different braking effect is generated in the individual door bands or window bands. In the case of very large manufacturing tolerances, this can lead to the fact that in the case of several door or window hinges, one or more of the door or window hinges will not absorb the weight of the door leaf or of the window sash and transmit it to the door or window frame, thus not wearing it, and thus none at all Cause braking effect. The braking effect is then effected only by the other, supporting door bands or window bands. This can lead to a reduction in the braking effect and increased wear of the still-bearing door or window hinges. Due to the mobility of the pin in this advantageous embodiment in the direction of its longitudinal axis relative to the wing part or the frame part on which it is arranged, and thereby possible tolerance compensation for the distance between the wing part and frame part is achieved that all door hinges or window hinges of a door or a window Wear evenly and create a uniform braking effect for all door hinges in a similar area. If necessary, the braking torques caused by the individual bands can also be set differently among one another with this embodiment.

In a further advantageous embodiment of the invention, a guide device is provided between the pin and the wing part or the frame part on which the pin is arranged. By means of this guide device, the pin is guided relative to the wing part or the frame part on which it is arranged in the direction of its longitudinal axis, in the direction of which it is thus movable. At the same time is prevented by the guide device, that the pin relative to the wing part or the frame part on which it is arranged, twisted. By this rotationally fixed arrangement of the pin in the wing part or the frame part in conjunction with the rotationally fixed arrangement of the bearing cap on the pin friction between the bearing cap and receiving cavity can be ensured, as far as the inner and outer mold surface are at least partially together, and thus the desired braking effect between the wing part and the frame part. By the leadership of the pin in the guide device in the direction of its longitudinal axis tolerances between the wing part and frame part, which occur in the assembled state of the door or window hinge, can be compensated, which may be required if the door leaf or the window sash to several hinges or window ribbons in Frame is attached.

Furthermore, it is advantageous, in particular, when the journal has a foot part, and the wing part or the frame part, on which the journal is arranged, has a recess. The foot of the pin can then be placed in the recess. Furthermore, the foot part can have a guide projection. The guide projection engages, when the foot part of the pin is arranged in the recess, in a groove formed in the recess. By engaging the guide projection in the groove of the pin with its foot is rotationally fixed in the recess, which is formed in the wing part or the frame part, on which the pin is arranged, held. Alternatively, the groove may also be formed in the foot part and the guide projection in the recess.

If an adjusting screw is provided in the wing part or the frame part on which the pin is arranged, this can be used to change the position of the pin in the wing part or the frame part on which the pin is arranged. The pin is moved by adjusting the adjusting screw in the direction of its longitudinal axis relative to the wing part or the frame part on which it is arranged. Through this adjustment screw, an adjustment of the pin position, and thus also the position of the arranged on the pin bearing attachment relative to the receiving cavity of the not provided with the pin wing part or frame part can be changed during assembly of the door hinge or the door from outside the door hinge. By an adjusting screw with a corresponding, in particular self-locking, thread pitch is a stepless fine adjustment of the distance between the journal and bearing attachment of one part and receiving cavity of the other part, and thus the braking action between the wing and frame part by moving the pin in the direction of its longitudinal axis, possible. If the adjusting screw is accessible from outside the door hinge, the adjustment can be made even when the door is mounted, and in particular after a longer period of time, when different wear on different bands occurs.

In a further advantageous embodiment, the bearing attachment on a breakthrough. This breakthrough is preferably arranged in the region of an end face of the pin. Through the breakthrough, the face is at least partially or completely exposed. At the end face of the pin is thus at least partially not covered by the bearing cap. As a result, the end face of the pin in the non-assembled state of the door hinge is at least partially freely accessible.

In a particularly advantageous embodiment of the invention, the frame part or the wing part, which is not provided with the pin, a magnetic receiving cavity. In the magnet receiving cavity, a magnet is arranged in the assembled state of the door hinge. At the same time, the pin has magnetic properties. These may be any magnetic properties, but with an effect that allows forces to be generated between the magnet in the magnet receiving cavity and the journal by magnetic interaction. The forces caused by the interaction of the magnetic force of the magnet with the pin dampen or brake a rotational movement between the wing part or the frame part. It is advantageous if the magnetic fields generated by the magnet with the opposing fields of the pin, which are generated when the magnet cooperates with the pin, repel. But other types of interaction between the magnetic force of the magnet and the pin, which are adapted to generate forces such that a rotational movement between the wing part and the frame part is attenuated or braked, can be used in this embodiment.

In an advantageous embodiment, the magnet is movable in the magnet receiving cavity. It is preferably arranged in the magnet receiving cavity so that it is movable in the longitudinal direction of the pin. Thereby, the distance of the magnet to the pin, and in particular to the end face of the pin, can be varied. This also changes the magnetic forces between the magnets and the pin.

It is particularly advantageous if the magnet rests against the end face of the pin when the door hinge or the window hinge is mounted. This can be effected by either fixing the magnet in the magnet receiving cavity so as to abut the end face of the magnet or by the movement of the magnet in the magnet receiving cavity when it is movably arranged there in the longitudinal direction of the journal. If the magnet is in the assembled state of the door hinge or the window hinge on the end face of the pin, so are generated by the interaction of the magnet with the pin friction forces between the magnet and the end face of the pin. By these frictional forces between the magnet and the end face of the pin, an additional braking effect between the frame part and the wing part is caused. This braking effect acts in addition to the braking action by the cooperation of the conical inner surface of the receiving cavity with the conical outer surface of the bearing cap as well as the magnetic forces, which are caused by the interaction between the magnet and the pin. By this additional braking action by the frictional forces between the magnet and the end face of the pin is thus also counteracted a rotational movement of the wing part relative to the frame part.

It is advantageous if a stop is formed in the frame part or the wing part in which the magnet is arranged. By this stop the mobility of the magnet is limited in the magnet receiving cavity. This can on the one hand enable easier installation. The magnet is then inserted into the magnet receiving cavity. The stop prevents the magnet from falling out in the direction of the receiving cavity from the frame part or the wing part in which it is arranged. On the other hand, the distance between the magnet and the end face of the pin can also be predetermined by the stop. This causes the determination of both the magnetic forces between the magnet and the pin and the frictional forces between the magnet and the end face of the pin. If the stop is arranged so that the magnet is spaced in the mounted state to the end face of the pin, so frictional forces between the magnet and the end face of the pin are prevented. Then only magnetic forces work. These magnetic forces are set by the determination of the distance between the magnet and the end face of the pin by appropriate arrangement of the stop.

If the magnet in the magnet receiving cavity is arranged rotationally fixed, it can not rotate relative to the wing part or the frame part, in which the magnet is arranged. Thereby, the forces required to produce a damping or braking of the rotational movement between the wing part and the frame part can be transmitted from the magnet directly over the wall of the magnet receiving cavity to the wing part or the frame part in which the magnet is arranged.

If the magnet receiving cavity has an opening, then the magnet can easily be introduced through this opening into the frame part or wing part. This opening is preferably on the receiving cavity facing away from the side of the wing or frame part, d. H. arranged the side facing away from the other wing or frame part of the wing or frame part with magnet. This facilitates the assembly. In addition, the magnet can then, for example, when its magnetic effect wears off or other wear has occurred, exchanged or exchanged for stronger magnets. However, the opening of the magnet receiving cavity may also be in a connection to the receiving cavity. Then, the magnet may be inserted into the magnet receiving cavity through the receiving cavity.

The opening of the magnet receiving cavity, through which the magnet is inserted into the frame part or wing part, can be closed by a cap. This prevents the magnet from being lost during transport, for example. The cap also prevents soiling of the magnet receiving cavity. It is prevented that dirt gets through the magnet receiving cavity on the bearing cap of the pin and dirty it and leads to increased wear.

In a further advantageous embodiment of the invention, the pin and the not provided with the pin frame part or wing part are magnetized. Due to the magnetization on the pin and not on the generated with the pin provided frame or wing part magnetic poles. The magnetic poles of the pin and the untapped frame or wing portion may either attract or repel. By the attraction or repulsion, a further braking effect between the provided with the pin frame or wing part and the part not provided with the pin is generated. This further braking action also counteracts a rotational movement of the wing part relative to the frame part. It thus supports the braking effect, which is caused by the interaction of the conical outer surface of the bearing cap and the conical inner surface of the receiving cavity. It can also, as far as provided, support the further braking effects, ie the braking effect by magnetic forces between the pin and the magnet arranged in the receiving cavity and the braking effect by frictional forces between the magnet and the end face of the pin.

In a further particularly advantageous embodiment of the invention, a ring made of elastic material, in particular plastic, is arranged between the wing part and the frame part, in particular between their mutually facing end faces. This ring is compressed in the assembled state of the door or window hinge by the weight of the door leaf or window sash, which is transmitted between the wing part and the frame part. The arranged between the wing part and the frame part ring of elastic material opposes a rotational movement of the wing part relative to the frame part by friction with the wing and the frame part an additional braking action. The fact that the ring is compressed by the weight of the door leaf or sash, the friction between the outer surface of the bearing surface and the inner surface of the receiving cavity cavity, and the braking effect caused thereby is not canceled. Rather, the ring is compressed such that the outer surface of the bearing cap and the inner surface of the receiving cavity in the assembled state of the door or window hinge continue to at least partially abut each other. The forces between Wing part and frame part are thus partially transmitted by the juxtaposition of the inner surface of the receiving cavity and the outer surface of the bearing cup, on the other hand via the ring between the wing part and frame part. Both the interaction of the inner surface of the receiving cavity with the outer surface of the bearing cup and the ring between the wing portion and the frame member each produce a braking action, which counteracts a rotational movement of the wing portion relative to the frame member.

In an advantageous embodiment of the invention, the ring of elastic material is designed such that it, when a door or a window sash has a mass of about 30 kg and the wing is attached to the door frame or window frame by two equally heavily loaded door hinges or window hinges is compressed in an axial direction of the pin of each door hinge or the window hinge in a range between 5% and 35% of its thickness. This compression refers to the expansion of the ring in its built-in door or window belt uncompressed state in the axial direction of the pin before applying the weight of the door or the window. It is assumed that each of the two hinges or bands of windows to which the door or window sash is attached to the door frame or sash carries approximately the same weight portion of the sash or sash, ie approximately 15 kg each. This uniform support can be achieved when mounting either without tolerances, or when at least one of the hinges or bands is adjustable, as described above, so that each of the two hinges or ribbons is uniformly supported. Within the described strain range, to produce the described effect, the ring in an axial direction of the pin is preferably compressed between 10% and 30% relative to its uncompressed extent in the axial direction of the pin. More preferably, compression is 15% to 25% to produce the desired effect.

In a further advantageous embodiment, either the wing part or the frame part, in particular in one or both of the mutually facing end faces of these parts, an undercut which is designed so that in it the ring can be arranged such that the desired compression and the desired braking effect is generated. In particular, the width of the undercut is greater than the radial width of the ring in the unloaded state, but preferably greater than the radial width of the ring in the loaded by a door leaf or sash condition of the band. In this case, the ring in the undercut movable, in particular rotatable, be arranged so that frictional forces are transmitted between the ring and the surface of the undercut. The undercut is to be designed so that, moreover, an interaction between a part of the surface of the ring and the surface, in particular end face of the wing or frame part without undercut is possible to frictional forces and weight forces between the wing and frame part about the ring transfer.

In a further advantageous embodiment, the ring is arranged rotationally fixed in the undercut. Due to the rotationally fixed arrangement, it can not move relative to the wing part or the frame part in which the undercut is arranged. As a result, the friction of the ring with the other, no undercut having, part can be increased.

If the surface of the ring is roughened, the friction between ring and frame part and / or wing part can be increased. Also, the surfaces of the frame and wing portion rubbing on the ring can be roughened, nubs, etc., to increase the friction between these parts and the ring.

In an advantageous embodiment, the undercut is arranged in the wing part or the frame part, on which the pin is arranged. The undercut is advantageously arranged annularly around the pin around there. In a further advantageous embodiment, the wing part or the frame part, in which no undercut is arranged, one or more projections. This projection cooperates in the assembled state of the door hinge or the window hinge by penetrating the elastic ring material with the ring and generates a braking effect in the circumferential direction between the ring and projection of the wing part or of the frame part. The projection can also help to compress the ring. Advantageously, the projection as well as the ring is circular, and the two are aligned in the axial direction to each other.

In a further advantageous embodiment is or are on the wing part or frame part, in which no undercut is formed, in particular its end face, a groove, which is designed in particular annular, or a plurality of grooves arranged. The groove has a bottom surface and side surfaces which abut partially in the assembled state of the door hinge or the window band on the surface of the ring, since at least compressed ring material, in particular uncompressed ring material at least partially extends axially into the groove or load the tape into the groove penetrates. By this concern, a braking effect between the ring and the surfaces, in particular the side surfaces of the groove is generated. Compared to versions without such a groove, the braking effect can be increased due to the groove by the enlargement of the surfaces with which the ring cooperates.

In a further advantageous embodiment, both the wing part and the frame part are provided with an undercut. The ring is arranged in the assembled state of the door or window hinge in each case to a part in each of the two undercuts. In the compressed state, in this embodiment, with a suitable arrangement of at least the recess provided in the part provided with the pin, the ring with its inside diameter lies at least partially against the pin. By touching the inner diameter of the ring with the surface of the (preferably with circular ring cross section provided) a frictional force between the inner diameter of the ring and the surface of the pin is created, which generates a movement of the wing member relative to the frame member opposite braking effect. Advantageously, the ring and the undercuts are dimensioned so that the ring rests in a compressed state on the bottom surfaces of both undercuts.

In an advantageous embodiment of the door or window hinge, in which both the wing part and the frame part are provided with an undercut and the inner diameter of the ring comes to rest on the pin, the ring is in the part which is not provided with the pin, arranged rotationally. Thereby, a rotation of the ring is prevented relative to this part and the friction relative to the part provided with the pin, both with the surface of the undercut, but in particular between the inner diameter of the ring and the surface of the pin increases.

In an advantageous embodiment of the door or window hinge, the outer surface of the bearing cap axially in succession has a conical section and / or a cylindrical portion, wherein preferably the conical portion is in the region of the free end of the support member of the pin and thus in the corresponding region of the outer surface or on the opposite, facing the journal-bearing part, end of the bearing cap. The outer surface of the receiving cavity has a shape suitable analogous thereto.

Thus, both a lower and an upper conical section may be present on the same bearing attachment, also as described below.

The cone angle of the conical portion is preferably between 3 ° and 11 °, more preferably between 5 ° and 9 °, and thus is large enough to avoid seizing of the superimposed conical surfaces, however still uses the wedge effect based braking force of the conical bearing surfaces.

• zwischen 3 mm und 7 mm
• und/oder zwischen dem 0,4-fachen und dem 0,9-fachen des Durchmessers des zylindrischen Tragteils des Zapfens.

The axial length of the conical section is

• between 3 mm and 7 mm
• and / or between 0.4 times and 0.9 times the diameter of the cylindrical supporting part of the spigot.

This length provides a sufficiently large contact surface to keep the surface pressure within an acceptable range.

• entweder geringer als 0,3 mm, besser geringer als 0,2 mm, besser geringer als 0,15 mm, besser geringer als 0,1 mm
• und/oder geringer als das 50-fache, besser geringer als das 75-fache, besser geringer als das 150-fache der Länge des zylindrischen Abschnitts des Lageraufsatzes.

So that the outer mold surface is guided sufficiently accurately with respect to the inner mold surface, the difference between the diameter of the outer mold surface of the bearing cap and the receiving cavity in the cylindrical portion

• either less than 0.3 mm, better less than 0.2 mm, better less than 0.15 mm, better less than 0.1 mm
• and / or less than 50 times, better less than 75 times, better less than 150 times the length of the cylindrical portion of the bearing cap.

In the door hinge or window hinge 1 of FIG. 1 a pin 4 is arranged on a frame part 3. Alternatively, it is structurally possible to arrange the pin 4 on the wing part 2. The pin 4 is at the in FIG. 1 embodiment shown not movable in the direction of its longitudinal axis 10 and this also not rotatable.

The wing part 2 has a receiving cavity 5, which in the in FIG. 1 shown embodiment is designed as a blind hole. The receiving cavity 5 has as a wall a conical inner molding surface 8. The diameter of the receiving cavity 5 on the frame part 3 facing side is greater than the diameter of the receiving cavity 5 on the side facing away from the frame part 3.

On the pin 4, a bearing cap 6 is arranged. The bearing cap 6 has a conical outer mold surface 7, which has the same cone angle as the inner mold surface 8. The outer mold surface 7 is mounted in State of the door or window hinge 1 of the inner surface 8 of the receiving cavity 5 faces. The pin 4 is in the in FIG. 1 illustrated embodiment of the door hinge or window hinge 1 designed as a circular cylinder. Its circumference is thus designed at its end facing the frame part 3 equal to its circumference at its end remote from the frame part 3 and annular.

The angular range of the cone angle as the angle between the generatrices (i.e., the outer molding surface) and the axis of the cone is in a range of 1 degree to 40 degrees, preferably in a range of 3 degrees to 25 degrees. even more advantageously in a range of 3 degrees to 15 degrees, more preferably in a range of 3 degrees to 11 degrees, more preferably in a range of 5 degrees to 9 degrees.

To arrange the bearing cap 6 rotationally fixed on the pin 4, an internal cavity is formed in the bearing cap 6 to receive the pin. This inner cavity is largely completely filled by the pin 4 after mounting the bearing cap 6 on the pin 4. Furthermore, the pin 4 in the in FIG. 1 illustrated embodiment, a groove 9. This groove extends in the in FIG. 1 illustrated embodiment over the entire length of the pin 4. In other embodiments, this groove 9 may extend only partially along the pin 4. On the bearing cap 6, a holding projection is formed on the surface of the inner cavity. This retaining projection engages, when the bearing cap 6 is arranged on the pin 4, in the groove 9 of the pin. As a result, a rotation of the bearing cap 6 about the longitudinal axis 10 of the pin 4 is prevented. There is thus positive locking between the bearing cap 6 and the pin 4 in order to arrange the bearing cap 6 rotatably on the pin 4.

In other embodiments, the rotationally fixed arrangement of the pin 4 can be effected on the bearing cap also by other means. In addition to a cohesive connection z. B. by gluing the bearing cap. 6 on the pin 4 is in particular, as in the embodiment according to FIG. 1 , a positive connection advantageous. Alternatively to the positive connection in FIG. 1 by a groove 9 in the pin 4 and a retaining projection in the bearing cap 6, the positive connection can also be achieved in that the pin 4 and the inner cavity of the bearing cap 6, in which the pin 4 is received, each having a suitable cross-sectional geometry through which a Anti-rotation between the bearing cap 6 and pin 4 is ensured. This can be achieved, for example, that the pin 4 has a square or polygonal profile, oval shaped or receives splines, and the inner cavity of the bearing cap 6 has a corresponding design, in order to interlock with the cross-sectional geometry of the pin 4 a positive rotation the bearing cap 6 and the pin 4 to form. In this case, the pin 4 is preferably cylindrical. But also a design of the pin 4, in which the cross section of the pin 4, starting from its the frame part 3 facing the end towards its end remote from the frame part 3, is conceivable.

In the in FIG. 1 illustrated assembled state of the door hinge or the window hinge 1, the bearing attachment 6 protrudes into the receiving cavity 5. In the in FIG. 1 illustrated embodiment also projects the pin 4, on which the bearing cap 6 is arranged in the receiving cavity 5 in. Like the inner molding surface 8 of the receiving cavity 5 of the wing part 2, the outer molding surface 7 of the arranged on the pin 4 of the frame part 3 bearing cap 6 is conical. The conical outer molding surface 7 of the bearing cap 6 is designed so that its circumference decreases from the end of the bearing cap 6 facing the frame part 3 towards the end of the bearing cap 6 facing away from the frame part 3.

In the assembled state, the outer mold surface 7 of the bearing cap 6 and the inner mold surface 8 of the receiving cavity 5 are at least partially adjacent to each other. For this it is necessary that between the wing part 2 and the frame part 3 remains a gap 28, so that the end faces of the wing part 2 and the frame part 3 do not come into concern and only the outer surface 7 of the bearing cap 6 and the inner surface 8 of the receiving cavity 5 abut each other and transmit forces between the wing part 2 and frame part 3. Due to the abutting outer molding surface 7 of the bearing cap 6 and the inner mold surface 8 of the receiving cavity 5 are in the assembled state of the door hinge or window hinge 1 by the transmitted between wing part 2 and frame part 3 forces, resulting primarily from the weight forces of the door or window sash, but possibly also by a tension of several door or window bands against each other during assembly, frictional forces between the conical surfaces 7, 8 generated. These forces generate a braking action, which is opposite to a rotational movement of the wing part 2 relative to the frame part 3 opposite.

In the execution according to Fig. 1 Only forces between the conical shaped surfaces 7, 8, which cause a braking action opposite to a rotational movement of the wing part 2 relative to the frame part 3, are generated. In the case of wear or, as far as the bearing cap 6 is elastic, by its compression with larger forces transmitted between the wing part 2 and the frame part 3, there may be a slight displacement of the wing part 2 in the direction of the longitudinal axis 10 of the pin on the frame part 3. The gap 28 must therefore always be dimensioned so that even with this displacement of the wing part 2 relative to the frame part 3, the gap 28 does not disappear, so that the forces between wing part 2 and frame part 3 always only by the contact surface of the conical outer surface 7 of the bearing cap. 6 be transmitted to the conical inner surface 8 of the receiving cavity 5 of the wing part 2.

In the in FIG. 2 shown embodiment of a door hinge or window hinge 1 is the pin 4 in the direction of its longitudinal axis 10 relative to the frame part 3, on which the pin 4 is arranged, movable. This is a tolerance compensation regarding the distance of wing part 2 and frame part 3 in the assembled state of the door hinge 1 possible.

As already in the in FIG. 1 illustrated embodiment, the wing part 2 has a receiving cavity 5. This again has a conical inner molding surface 8. On the pin 4, a bearing cap 6 is arranged. This also has, as in the in FIG. 1 The bearing cap 6 is in turn rotationally mounted on the pin 4, wherein the torsional strength by a positive connection between the bearing cap 6 and the pin 4 with the already at FIG. 1 described constructive features (not shown here) is effected.

In the in FIG. 2 illustrated embodiment with movable in the direction of the longitudinal axis 10 pin 4, the pin 4 has a foot 12. In the frame part 3, a recess 11 is formed, in which, when the pin 4 is mounted in the frame part, the foot part 12 of the pin 4 is arranged. In order to arrange the foot part of the pin rotationally fixed in the recess 11 of the frame part 3, the recess 11 at least partially, in the in Fig. 2 illustrated embodiment over its entire length, a groove into which a formed on the foot part 12 guide projection 13 engages. Thereby, the pin 4 can be moved with its foot part 12 in the recess 11 of the frame part 3 in the longitudinal direction 10 of the pin 4. However, it can not rotate about the longitudinal axis 10.

At the in FIG. 2 illustrated embodiment, the frame part 3, then to the recess 11, further comprises a bore 26 with a thread 27. In the thread 27 of the bore 26 an adjusting screw 14 is screwed from the end facing away from the pin 4 of the frame part 3 ago. By turning the adjusting screw 14, this moves in the longitudinal direction 10 in the bore 26. The screw 14 touches at its end opposite the screw head end face of the foot portion 12 of the pin 4. When turning the screw 14 and thereby caused longitudinal movement of the screw 14 in Direction of the longitudinal axis 10 of Pin 4 is caused by the contact between the screw head opposite end of the screw 14 and the end face of the foot portion 12 of the pin 4, a longitudinal movement of the foot portion 12, and thus of the pin 4, in the direction of the longitudinal axis 10 of the pin 4. Thereby, the pin 4 in the direction of the wing part 2 or (by means of the forces acting on the pin) can be moved in the opposite direction.

As a result, a tolerance compensation between the wing part 2 and the frame part 3 is possible, so that even with tolerances between the wing part 2 and frame part 3 by turning the adjusting screw 14 can be achieved that the conical inner surface 8 of the receiving cavity 5 of the wing part 2 always at least partially on the conically shaped outer surface 7 of the bearing cap 6 is applied so that forces between outer surface 7 and inner surface 8 are transmitted, frictional forces are generated by these forces, and thus a rotational movement of the wing part 2 relative to the frame part 3 is always set against braking. By balancing the tolerances by the movement of the pin 4 in the longitudinal direction 10, the gap 28 between the wing part 2 and frame part 3 can always be maintained, so that wing part 2 and frame part 3 does not come to rest there and the braking effect between the inner surface 8 and outer surface form surface. 7 would be lifted.

The screw head of the adjusting screw 14 can be reached through the bore 26 in the frame part 3 of the wing part 2 opposite side. Even in the assembled state of the door or window hinge 1 thus the adjusting screw 14 is accessible, so that a tolerance compensation between wing part 2 and frame part 3 is always possible when the door or window hinge 1 are mounted in the door frame or window frame.

The tolerance compensation in the execution according to FIG. 2 is particularly advantageous when a door leaf or a window sash with at least two door or window hinges is attached to the door or window frame. Then, due to manufacturing tolerances, it will usually be necessary to achieve by using at least one door hinge or window hinge with longitudinally movable pin 4 that at both door or window hinges, the outer mold surfaces 7 of the bearing cap 6 at least partially on the inner mold surfaces 8 of the receiving cavity 5 abut. Thus, forces are transferred between the wing part 2 and frame part 3 on these surface touches in both hinges or window hinges, so that in both hinges or window hinges about the same braking effect is generated and also a uniform load, and thus a uniform wear. In the second door or window hinge used, however, it may be one with a rigid pin, z. B. according to the in Fig. 1 illustrated embodiment, act.

Also at the in FIG. 2 shown embodiment, it is structurally readily possible, the pin 4 and thus the entire mechanism for moving the pin 4 in the longitudinal direction 10 not, as shown here, to arrange in the frame part 3, but in the wing part 2, and the receiving cavity 5 thus not in the wing part. 2 to arrange, but in the frame part. 3

In the in FIG. 2 In the embodiment shown, an undercut 24 is additionally formed in the frame part 3 on its side facing the wing part 2. The foot part 12 has a shoulder 29 which is enlarged in diameter relative to the diameter of the foot part 12. The paragraph 29 is arranged in the undercut 24. The diameter of the shoulder 29 is also greater than the diameter of the recess 11. By the shoulder 29, the movement of the foot portion 12 of the pin 4 in the longitudinal direction 10 of the pin is limited to the frame part 3 in cooperation with an end face of the undercut 24. This prevents that, by adjusting the adjusting screw 14, the foot part 12 moves too far into the recess 11 of the frame part 3 and thus the gap 28 between the wing part 2 and the frame part 3 disappears. However, there are also versions of a door or window hinge without undercut 24 and paragraph 29 possible.

In the in FIG. 3 As shown, an additional braking action or damping of the rotational movement between the wing part 2 and the frame part 3 is effected by a magnet 18 in cooperation with the pin 4.

Also at the in FIG. 3 shown embodiment of a door or window hinge 1, the pin 4 is arranged on the frame part 3. The pin can on the frame part as in the embodiment of FIG. 1 be arranged immovable. He can alternatively, as in the in FIG. 2 shown embodiment, be arranged movable in the frame part in the direction of the longitudinal axis 10 of the pin 4. In this case, the mechanism for moving the pin 4 in the longitudinal direction 10 as in the embodiment according to FIG. 2 be designed. Other embodiments, with which the pin 4 is movably arranged in the frame part 3, are possible.

As in the previous remarks is also in the in FIG. 3 shown execution on the pin 4, a bearing cap 6 is arranged. Here, the bearing cap 6 is arranged here form-fitting manner on the pin 4. As with the execution Fig. 1 is formed in the pin 4, a groove 9, in which a projection which is formed in the inner cavity of the bearing cap 6, engages. Again, other structural designs are possible, as above Fig. 1 described, with which the bearing cap 6 rotatably mounted on the pin 4 is arranged.

In the in FIG. 3 As shown embodiment, the bearing cap 6 in the area of the end face 15 of the pin 4 has an opening 16. The end face 15 of the pin 4 is completely free in the embodiment shown.

In the assembled state of the door hinge or the window hinge 1, the bearing cap 6 protrudes, as well as in the embodiments of FIG. 1 and 2 , at least partially into the receiving cavity 5 of the wing part 2 inside. The conical inner surface 8 of the receiving cavity 5 and the conical outer surface 7 of the bearing cap 6 are at least partly together. Between the wing part 2 and the frame part 3, a gap remains 28. By the juxtaposition of the inner surface 8 of the receiving cavity 5 and the outer surface 7 of the bearing cap 6 is caused by the forces transmitted there, a rotational movement of the wing part 2 relative to the frame part 3 oppositely acting braking force.

In addition to this braking force between the outer molding surface 7 of the bearing cap 6 and the inner molding surface 8 of the receiving cavity 5, an additional braking force is caused by the interaction between a magnet 18 and the pin 4. The pin 4 has suitable magnetic properties for this purpose. He is thus to choose from a material that reacts to the magnetic force of the magnet 18 caused by magnetic force opposing forces of the pin 4. The pin 4 can also actively generate its own magnetic forces, for example, by being made of magnetic material or magnetized suitable.

For receiving the magnet 18, the wing part 2 has a magnet receiving cavity 17. The magnet 18 is inserted through an opening 20 in the wing part 2 in the receiving cavity 17. The opening 20 of the magnet receiving cavity 17 can be closed by a cap 21. This can prevent the magnet 18 from being removed from the receiving cavity 17. In particular, the cap 21 prevents contamination of the magnet receiving cavity 17 and the receiving cavity. 5

The magnetic forces exerted by the magnet 18 cooperate with the pin 4 so that a rotational movement between the wing part 2 and the frame part 3 is damped or braked. Through the opening 16 in the bearing cap 6 in the region of the end face 15 of the pin 4 ensures that between the magnet 18 and the end face 15 of the pin 4 as large as possible magnetic forces can act.

But even if the bearing cap 6 has no breakthrough in the area of the end face 15 of the pin 4, act between magnet 18 and pin 4 magnetic forces that cause a braking action between the wing part 2 and frame part 3.

A braking effect caused by the provision of a magnet 18 can on the one hand be effected in that only magnetic forces act between the magnet 18 and the end face 15 of the pin 4. The magnet 18 then does not touch the end face 15 of the pin 4, and no further braking forces caused by friction between the magnet 18 and the end face 15 of the pin 4 are generated. There thus remains always a gap between the end face 15 of the pin 4 and the magnet. As a result, there is also no wear due to friction between the magnet 18 and the end face 15 of the pin 4.

In the in FIG. 3 In the embodiment shown, the magnet 18 is arranged in the magnet receiving cavity 17 such that it can not rotate about the longitudinal axis 10 of the journal. However, a displacement of the magnet 18 in the direction of the longitudinal axis 10 is possible. The magnet 18 has for this purpose guides 30 which engage in mating surfaces of the wall of the Magnetaufnahmeholraums 17 and cause the longitudinal movement of the magnet 18, but prevent its rotation about the longitudinal axis 10.

In this embodiment, the magnet 18, as far as its longitudinal movement has not yet been limited by a stop 19 in the receiving cavity 17, on the end face 15 of the pin 4 (in Fig. 3 For better clarity between magnet 18 and end face 15 of the pin 4, a gap was drawn, which is not present in operation). By the interaction of the magnet with the suitable magnetic properties having pin 4 attracting forces between the magnet 18 and the end face 15 of the pin 4 arise. These attractive forces cause friction between the end face 15 of the pin 4 and the magnet 18. The braking effect by the magnetically induced frictional forces acts in addition to the braking effect, which is caused by the pure magnetic forces between the magnet 18 and the end face 15 of the pin 4. It also acts in addition to the braking action by the forces transmitted between the outer surface 7 of the bearing cap 6 and the inner surface 8 of the receiving cavity 5 of the wing part 2 and generate frictional forces there. This embodiment thus makes it possible to generate additional braking forces in addition to the braking effects caused by the weight force of the window or door wing between the outer molding surface 7 of the bearing cap 6 and the inner molding surface 8 of the receiving cavity 5. These are independent of the weight of the window or door leaf. The braking forces are, as described above, on the one hand generated by pure magnetic forces between the magnet 18 and the end face 15 of the pin 4. You can still be reinforced by the frictional forces between the magnet 18 and the end face 15 of the pin in a longitudinally movable 10 of the pin 4 magnet 18 when it rests against the end face 15 of the pin 4.

In the in Fig. 3 illustrated embodiment, the bearing cap 6 in the region of the end face 15 of the pin 4 on an opening 16. The magnet 18 thus rubs directly against the end face 15 of the pin 4. If the bearing cap 6 has no breakthrough, the magnet rubs against a part of the bearing cap itself. At this point, the friction with the magnet can be increased, for example, by roughening, nubs become.

The stop 19 in the magnet receiving cavity 17 limits the movement of the magnet 18 in the direction of the longitudinal axis 10 of the pin. If the magnet 18 does not touch the end face 15 of the pin, then its longitudinal movement in this direction can be limited by the stop 19. In one too in Fig. 3 illustrated embodiment, in which the magnet 18 rests against the end face 15 of the pin 4 and its movement is thus not limited in operation by the stopper 19, is slipped out of the magnet from the stop 19 in the unmounted state of the door or window belt 1 Magnetic receiving cavity 17 in the direction of Receiving cavity 5 of the wing part prevents, as well as a loss of the magnet by falling out during disassembly when z. B. the door is removed.

An additional braking effect between the wing part 2 and the frame part 3 can also be caused by the fact that the pin 4 and the wing part 2 or frame part 3 not provided with the pin 4 are magnetized in such a way that the pin 4 and the part not provided with the pin 4 are magnetic poles have, with the magnetic poles of the pin and not provided with the pin 4 part either attract or repel. By attracting or repelling the magnetic poles of the pin 4 and the part not provided with the pin 4, a further braking effect can be effected. This can also be done independently of the arrangement of a magnet 18 in the wing or frame part, ie in addition to the in Fig. 1 to 3 shown embodiments.

In the in FIG. 4 As shown, an additional braking or damping action between the wing part 2 and the frame part 3 is effected by a ring 22 arranged between the wing part 2 and the frame part 3.

The ring may be in an embodiment of a door hinge or window hinge, as described above for the Figures 1 - 3 has been described.

However, the ring can also, as in Fig. 4 represented, are arranged in an embodiment of a door hinge or window hinge, in which on the pin 4 no bearing attachment is arranged. A braking effect is thus not already generated there by interaction of conical molding surfaces. In this embodiment, therefore, only as in conventional door hinges a cylindrical pin 4 on the frame part 3 (or on the wing part 2) is arranged, which projects into a receiving cavity of the wing part 2 (or the frame part 3).

In the in FIG. 4 illustrated embodiment, the pin 4 is movable in the direction of its longitudinal axis 10, as already in the embodiment according to Fig. 2 described. As in the FIG. 2 illustrated embodiment, it has a foot part 12 which is arranged in a recess 11 of the frame part 3. In the foot part 12, a guide projection 13 is formed. The guide projection 13 of the foot engages in a groove which is arranged in the wall of the recess 11 of the frame part 3, a. Characterized a rotational movement of the pin 4 is prevented about its longitudinal axis 10 and the movement is guided in the direction of the longitudinal axis.

The frame part 3 has in the in FIG. 4 shown embodiment as well as in the execution FIG. 2 in connection with the recess 11, a bore 26. The wall of the bore 26 has a thread 27 into which an adjusting screw 14 is screwed. By turning the adjusting screw 14, the head is accessible through the opening 26 in the assembled state of the door or window hinge, as in the embodiment according to FIG. 2 the pin 4 are moved in the longitudinal direction 10 to compensate for tolerances between the wing part 2 and the frame part 3 and always maintain a gap 28 between them.

The braking effect between the wing part 2 and the frame part 3 is caused by the elastic ring 22. In the in FIG. 4 illustrated embodiment, the ring 22 in an annular recess 24, which is formed in the wing part 2 facing end face in the frame part 3 around the pin 4 around. However, the ring 22 may be without undercut 24 between wing part 2 and frame part 3.

The ring 22 is in the in FIG. 4 illustrated embodiment arranged around the pin 4 around. It has an opening through which the pin 4 protrudes in the mounted state. The ring 22 protrudes in the in FIG. 4 shown embodiment of the undercut 24 axially in the direction of the wing part 2 out and into the gap 28 between the wing part 2 and frame part 3 inside.

In the in FIG. 4 illustrated embodiment, an annular groove 25 is formed in alignment with the undercut 24 in the end face of the wing part 2. The ring 22 projects in the mounted state of the door or window hinge 1 axially in this groove 25 into it. He touches her face and / or her side surfaces there. Due to the friction of the ring 22 on the end and / or side surfaces of the groove 25, a braking action between the wing part 2 and the frame part 3 is caused in the assembled state.

Preferably, the ring 22 is rotatably disposed in the undercut 24, for example by positive engagement or bonding. But even with an undercut 24 largely freely rotatable ring 22 braking forces are caused by the friction of the ring 22 with the undercut 24 and the walls of the groove 25.

To induce a braking effect, it is advantageous, but not necessary, in the wing part 2 as in the embodiment according to Fig. 4 to arrange a groove 25 in which a portion of the ring 22 comes to rest in the mounted state of the door or window hinge 1. Instead, a braking effect can also be brought about by the friction between the surface of the ring 22 and a projection or an end face of the wing part 2 formed on the wing part 2.

For versions in which as in the following Fig. 1 to 3 on the pin 4, a bearing cap 6 is arranged, the conical outer surface 7 in cooperation with a conical inner surface 8 of the receiving cavity generates a braking effect, and in which an additional ring 22 between the wing part 2 and frame part 3 is provided, the weight of the door or of the sash of the wing part 2 on the frame part 3 to a part on the surface contact between the conical inner surface 7 and the outer surface conical surface 8, transmitted to the other part via the ring 22. The ring must therefore be designed so that the surface contact between the outer surface of the Bearing top 6 and inner surface 8 of the receiving cavity 5 is not canceled, so that the braking effect is not eliminated by this surface contact.

This is achieved by a ring 22 made of an elastic material. This is compressed in the assembled state of the door or window hinge 1 by the weight of the door leaf or window sash. It is compressed so far that the outer surface 7 of the bearing cap 6 and the inner surface 8 of the receiving cavity 5 in the assembled state of the door or window hinge 1 continue to at least partially abut each other, so that a further braking effect is generated by the surface contact. The braking effect through this surface contact is thus only reduced by the provision of the ring. Through the ring 22, an additional braking action between the wing part 2 and the frame part 3 is generated in the manner described above.

The distribution of the braking effect between the surface contact of the inner and outer mold surface on the one hand and the braking action through the ring 22 between the wing part 2 and the frame part 3 on the other hand can be adjusted initially by selecting an elastic ring material with a suitable modulus of elasticity.

In the in FIG. 4 As shown embodiment, the distribution can also be adjusted by displacement of the pin 4 in its longitudinal direction 10. The foot part 12 of the pin 4 is located far in the recess 11 of the frame part 3, then there is only a slight, in the extreme case no surface contact between the outer surface 7 of the bearing cap 6 and the inner surface 8 of the receiving cavity 5, so that only generates low braking forces become. The forces between the wing part 2 and the frame part 3 are then largely or completely transmitted via the ring 22.

If, however, the foot part 12 is moved out of the recess 11 in the direction of the wing part 2 by the adjusting screw 14, then the gap 28 becomes enlarged between wing part 2 and frame part 3. In the limiting case, the gap 28 is so large that the ring 22 is no longer present on the wing part 2, so that this braking effect is canceled. The braking action between the wing part and the frame part is then caused exclusively by the surface contact between the outer molding surface 7 of the bearing cap and the inner molding surface 8 of the receiving cavity.

By a paragraph 29 of the foot part 12 can also in the in FIG. 4 shown embodiment, the foot part 12 is moved too far into the frame part 3, so that thereby the surface contact between outer surface 7 of the bearing cap 6 and inner surface 8 of the receiving cavity 5 is repealed, the forces between the wing part 2 and frame part 3 then only about the ring 22 are transmitted, and thus the braking effect between the wing part 2 and frame part 3 is almost exclusively effected by the ring 22.

Also at the in FIG. 4 As shown embodiment, the pin 4 can be arranged instead of the frame part 3 in the wing part 2, and the receiving cavity 5 are arranged to receive the pin 4 in the frame part 3 instead of in the wing part 2.

• Bei der Lösung gemäß Figur 5 ist ein konischer Abschnitt 32 der Aussenformfläche 7 des Lageraufsatzes 6 nur in dem unteren Bereich, also zugewandt demjenigen Teil 2 oder 3, welches den Lagerzapfen 4 drehfest trägt, in diesem Fall dem Rahmenteil 3, des Lageraufsatzes 6 vorhanden, über die restliche Länge 35 besitzt die Aussenformfläche 7 des Lageraufsatzes 6 eine zylindrische Form und bildet einen zylindrischen Abschnitt 33.

FIG. 5 and 6 show in an enlarged view of the wing part 2 with the adjacent region of the frame part 3 - regardless of whether in the frame part 3 a set screw is present or not, and regardless of whether the pin 4 is integrally formed with the frame part 3 or as a separate part with his foot in the frame part 3 inserted and protrudes only with its support member 4 a in the wing part 2 - each a solution in which the peripheral surface of the support member 4 a is particularly cylindrical, but the peripheral surface, so the outer surface 7 of it on mated bearing cap 6 only partially funny is:

In the solution according to FIG. 6 is a conical portion 32 of the outer mold surface 7 of the bearing cap 6 only in the upper region, ie facing away from that part 2 or 3, which rotatably carries the bearing pin 4, in this case of the frame part 3, the bearing cap 6 present over the remaining length 35 has the outer mold surface 7 of the bearing cap 6 has a cylindrical shape and forms a cylindrical portion 33rd
the inner molding surface 8 of the receiving cavity 5 is designed analogously to the outer molding surface 7, thus has in the corresponding axial portion a cylindrical portion and a conical portion.

In this case, should be in the cylindrical portion, in particular at the end remote from the conical portion of the cylindrical portion, the difference between the diameter of the outer mold surface 7 and the diameter of the inner mold surface 8 below a predetermined threshold, said difference being twice the value of in the Figures 5 and 6 only one-sided drawn radial clearance 34 is.

In the conical portion 32, the cone angle 31 between a lateral surface of the conical portion 32 and the longitudinal axis 10 of the pin 4 is preferably larger than in the recognizable Figures 1-3 in which the conical section 32 preferably extends virtually over the entire axial length of the bearing cap 6.
