Description

The invention relates to a hinge with a body-side hinge part which can be preassembled on a carcass and a door-side hinge part which can be preassembled on a door leaf, according to the preamble of claim 1.

Multi-joint hinges often have a three-dimensional adjustment on the frame part in a hinge arm and have due to the hinge mechanism usually a restricted opening angle. Since the multi-joint hinges have no visible parts to the outside, the correction of the door position, which is achieved by the adjustment of the hinges, not visible from the outside.

One-axis hinges have a large opening angle of 180-270 °, for example, thanks to an external axle. They usually have a two-dimensional adjustment consisting of a height adjustment on the body-side hinge part and a side adjustment in the door-side hinge part. In rare cases, a depth adjustment on the body side hinge part is realized by sitting in slots fixing screws. Since the lateral adjustment in the door-side hinge part can be realized, Einachsscharniere may have a flat resting on the carcass body side hinge part, usually in the form of a flat flange plate.

The multi-joint hinges are complex by the inclusion of all adjustment for the three-dimensional adjustment in the body-side hinge part and therefore have a high structure relative to the body. The lateral adjustment is realized as a rotation about a fulcrum located within the body-side hinge part, whereby the lateral adjustment also changes the depth setting. There are multi-joint hinges, which try with additional elements to avoid the simultaneous depth adjustment. As a result, the construction of the body side hinge part is more complex and the structure would be even larger. In order to achieve large opening angle, more joints are required, which also leads to more complex constructions that increases the height of the body-side hinge part. As a result, the use of such multi-joint hinges in cabinets with organization facilities is considerably more difficult or impossible.

In one-axis hinges, the outer axis is far out, especially if an opening angle of up to 270 ° is desired. If a correction of the position of the door leaf is required, the elements receiving the hinge axis are changed in their externally visible position from the door leaf or to adjacent joint axes, such as, for example Fig. 1 is apparent. In a required lateral adjustment creates a gap between the joint axis receiving elements and the door and after a height adjustment are the joint axis receiving elements of adjacent cabinets in different high positions. With twin hinges, only a joint height adjustment of both doors can be realized.

From the US 5,099,547 a generic multi-axis hinge is known in which the angular position of the door leaf is adjustable.

From the GB 2377729 A is a uniaxial hinge for a room or front door with a height adjustment known.

From the US 4,817,241 is a multi-axis hinge known for mitred doors.

The invention is therefore based on the object in a hinge of the type mentioned a simple lateral adjustment to allow such that no gap can arise on the door leaf.

To solve this problem serve the features of claim 1.

The invention provides that the lateral adjustment device pivots the body-side hinge part about an imaginary, parallel to the hinge axis extending pivot axis located in the body.

The lateral adjustment on the body-side hinge part makes it possible that the elements receiving the hinge axis are adjusted so that no gap between the elements receiving the hinge axis and the door leaf can arise.

The lateral adjustment on the body-side hinge part has the consequence that mitwandert with the correction of the lateral position of the door leaf not only the door, but also the fork part and the connecting part. This considerably increases the effective setting range. By mitverstellten, the hinge axis receiving elements, a better correction of the position of the adjacent door is possible, in particular no gap between the hinge axis receiving elements and the door leaf is formed.

The side adjusting device is arranged in the body-side hinge part. The pivoting of the body-side hinge part about a pivot axis lying in the body means that no gap between the elements receiving the hinge axis and the door can arise due to the lateral adjustment, because in the side adjustment of the door is moved. The rotation about the pivot axis located in the body leads to a negligible change in the depth position of the body-side hinge part in the lateral adjustment area, so that no additional corrective measures or correction elements are required.

The lateral adjustment is adjusted by operating a set screw.

The height adjustment device can be arranged in the hinge cup of the door-side hinge part and at least a blocking element, with which the adjusted height position of the door leaf relative to the body is fixable, wherein both the body side and the door side hinge parts may have a flange, which has a flat structure relative to the body or the door leaf.

The outsourcing of the height adjustment in the hinge cup of the door-side hinge part advantageously allows a simplification of the body-side hinge part, with the result that a small height of the body-side hinge part is made possible on the frame. Regardless of whether it is a multi-joint hinge or Einachsscharnier, in a three-dimensional adjustment from the outside can not be seen whether this has been made or not.

The arrangement of the height adjustment device in the hinge cup of the door-side hinge part has the advantage that the elements receiving the hinge axis remain fixed on the body-side hinge part and are not changed in their height position.

In addition, the door-side hinge part may have a side adjustment device.

The depth adjusting device may be provided on the body side hinge part.

Preferably, it is provided that the hinge is a Einachsscharnier with a single hinge axis. The distribution of the adjustment on the body-side hinge plate and the hinge cup of the door-side hinge part made possible advantageously a flat design of the Einachsscharniers.

The body-side hinge part has a fork part which receives the joint axis and a connecting part which is pivotably articulated to the fork part. Finally, the depth adjustment on the body side hinge part allows a relative displacement of the body side hinge part to the body, which allows for the outer hinge axis a large opening angle.

The connecting part may be inserted into the hinge cup, the connecting part being displaceable manually or with the aid of a height adjustment element in the vertical direction in the hinge cup along guide means and can be locked in a desired position by means of the blocking element. The arrangement of the height adjustment in the hinge cup of the door-side hinge part allows the height adjustment of the door leaf position without changing the position of the body-side hinge part and the joint axis receiving joints. With a twin hinge, the doors can be individually adjusted in height.

The depth adjustment allows a correction of changes in position of the inserted door leaf material and supplements the adjustability of the hinge to a three-dimensional adjustability.

The resting on the body part of the body side hinge part is plate-shaped flat and has a low overall height relative to the body. The construction height can be up to 7 mm, preferably to max. 5 mm limited.

The body-side hinge part and the door-side hinge part can be firmly connected to each other. Alternatively, the hinge parts are releasably coupled together by means of one or more additional elements. The coupling can be done either by means of screw connections, or by a clip connection, which allows a quick assembly. It is preferably provided that the clip connection is arranged in the door-side hinge part and that there preferably in the hinge cup.

The height adjustment device can have a height adjustment element, which contains, for example, at least one eccentric, which is supported on the hinge cup in such a way that the door-side hinge part changes its position in the height direction by turning the eccentric.

Alternatively, two eccentric elements can accommodate the connecting part between them, wherein the position of the connecting part in a free space of the hinge cup can be changed by adjusting both eccentrics in the vertical direction and can be fixed by means of the eccentric.

According to a further embodiment, it can be provided that the height adjustment element has a gear mounted in the connecting part, which meshes with a straight toothing of a guide device in the hinge cup, which runs parallel to the height direction.

The connecting part is adapted to linear guide means such that it is displaceable in the height direction within a free space in the hinge cup and can be fixed by means of the blocking element in a desired altitude.

The blocking element preferably consists of a locking screw with which the connecting part can be fixed in the desired position relative to the hinge cup.

The height adjustment in the hinge cup can on the one hand provide a manual displacement of the door or use a height adjustment. In this case, the height adjustment element may have at least one eccentric, which is supported on the hinge cup so that the door-side hinge part changes its position in the height direction by turning the eccentric.

It can also be provided two eccentric, which are arranged on both sides of a connecting part of the body side hinge part and can change the position of the connecting part in the height direction by turning both eccentric.

Alternatively, the height adjustment element can also have a toothed wheel that meshes with a straight-line toothing of the guide device in the hinge cup, which extends parallel to the height adjustment direction.

The locking element may consist of a screw which fixes the connecting part when tightening the screw in the current position, so that the door is fixed in the current position.

For the lateral adjustment is provided that the Seitenverstelleinrichtung has a cylindrical surface whose cylinder axis, located in the body imaginary pivot axis is. The cylindrical surface is a guide surface for the pivoting of the body-side hinge part. The pivot axis is parallel to the at least one hinge axis of the hinge.

The depth adjusting device may have a releasable latching device which holds in the blocking position the body-side hinge part in a central position relative to mounting screws sitting in the depth direction oval mounting holes. Such an adjustment is as a height adjustment basically already in the EP 1132560 described and can be used in the present hinge - rotated by 90 ° - as Tiefenverstelleinrichtung.

The clip connection has a spring element which is integral with the hinge cup and forms with the connecting part a height adjustment of the door wing allowing latching connection. Such a clip connection simplifies the production engineering effort and is cheaper to manufacture, wherein the spring element is engaged with the connecting part or a hinge arm of the hinge in such a way that a height adjustment relative to the connecting part or the hinge arm is not hindered. This is made possible by the fact that the spring element engages over a projection of the connecting part or hinge arm, wherein the hinge cup can nevertheless slide below the spring element in the height direction along a guide on the connecting part or the hinge arm.

Preferably, it further relates to a hinge in which a body-side hinge part and a door-side hinge part are hinged together, as well as coupled via a clip connection. The clip connection comprises a spring element which is integral with the hinge cup and forms with the connection part to the body side hinge part or hinge arm a locking connection allowing the height adjustment of the connection part.

In the following, embodiments of the invention will be explained in more detail with reference to the drawings.

Fig. 1 shows the occurring at a height adjustment and a lateral adjustment in a Einachsscharnier according to the prior art undesirable effects.

In Fig. 1 are two Einachsscharniere 1 side by side each connecting a door 3 with a frame or body 2. The body-side hinge part 4 has a joint part 7 receiving the fork part 9 and an articulated in the fork part 9 connecting part 14 to the door-side hinge part 6. These hinge elements are visible from the outside in a Einachsscharnier. In the case of a height adjustment of the body-side hinge part 4, the position of the hinge axis 7 receiving hinge elements shifts, so that looks like Fig. 1 can be seen, adjacent hinges 1 are not at the same height, whereby the aesthetic appearance of a piece of furniture can be affected.

On the right side, the effects of a conventional lateral adjustment are shown, wherein when making a correction to the lateral adjustment, a gap between the hinge axis 7 receiving hinge elements and the door leaf 3 may arise, which may also affect the aesthetic appearance of a piece of furniture.

Fig. 2 shows a cross section through the hinge 1, from which it can be seen that both the body-side hinge part 4 and the door-side hinge part have a flat construction relative to the body 2 and the door leaf 3. The door-side hinge part 6 has a recessed in the door 3 hinge cup 8.

This hinge cup 8 is in perspective view in FIG Fig. 3 shown. The hinge cup 8 is fixedly secured by means of an integrally connected thereto flange portion 36 in a recess of the door leaf 3, wherein the hinge cup 8 has a space 38 which allows the connecting part 14 of the body side hinge part 4 or a hinge arm of a multi-joint hinge can take different positions within the hinge cup 8 in height adjustment direction, which can be adjusted in height when held stationary connection part 14 or hinge arm of the door 3. For locking, the connecting part 14 or the hinge arm of a multi-joint hinge on a locking element 17, which may for example consist of a locking screw, which fixes the connecting part 14 and the hinge arm relative to the hinge cup 8 in a certain desired position. The hinge cup 8 has guide means 13 which are in engagement with the connecting part 14 and the hinge arm and form a linear guide in height adjustment direction. In Fig. 3 the guide means 12 consist of a straight rail element which cooperates with a recess 18 of the connecting part 14 adapted to this rail element. The height adjustment device 10 formed by these elements has at least one blocking element 17, wherein the door leaf 3 also manually without Höhenverstellelement 12 can be brought into a desired position and can be locked by means of the locking element 17.

Alternatively, a height adjustment element 12 may be provided which has an eccentric 15 which is supported against the hinge cup 8. By turning the eccentric 15, the height position of the door leaf 3 can be adjusted in relation to the connecting part 14 or to a hinge arm and then locked by means of the locking element 17.

It is understood that the height adjustment device 10 can be made very different.

For example, instead of the eccentric gear may be provided that meshes with a rack disposed on the guide means 13, or runs parallel to this. By turning the gear can then be made a height adjustment of the door leaf 3.

Another alternative is to provide an eccentric 15 above and below the connecting part 14 and the hinge arm, so that a total of two height adjustment elements are provided, both of which must be adjusted for adjusting the height position of the door leaf 3. Since both mounted in the hinge cup 8 eccentric can be biased against the connecting part 14, they also form the blocking element 17, so that an additional locking screw can be omitted.

The hinge cup 8 also receives a clip connection 22, by means of which the connecting part 14 or the hinge arm can be clipped into the hinge cup. For this purpose, the connecting part 14 is hooked at a first location 40 in the hinge cup and locked resiliently at a second location 42. The hinge cup 8 has for this purpose a spring element 34 which is integrally formed on the hinge cup 8 and protrudes from the flange portion 36 in the direction of the free space 38 of the hinge cup 8. A arranged on the hinge part 8 projection 44 is used to unlock the clip connection 22, for example by means of a tool.

With this tool, for example, the spring element 34 can be pushed back, whereby the connecting part 14 or. The hinge arm is released.

The peculiarity of this locking connection is that it does not hinder a height adjustment of the door leaf 3, namely by the spring element 34 can slide at its lower edge relative to the hinge part 14 and the hinge arm.

Fig. 4 shows the head-side hinge part 4 without the connecting part 14. Of the fork part 9, only one half is shown, since the flange portion 37 of the body-side hinge part 4 is cut and only the left half is shown.

The body-side hinge part 4 therefore consists of the flange portion 37, which cooperates with a base plate 46, which in turn is mounted directly on the body 2, or if the body-side hinge part 4 has a Tiefenverstellinrichtung 16, on a stationary mounted on the body 2 Tiefenverstellplatte 48 in different depth positions can be arranged.

Fig. 4 is an exploded view illustrating the integration of a Seitenverstelleinrichtung 5 and a depth adjustment 16 in the body side hinge part 4, in which a small height of the body-side hinge part 4 can be maintained.

The maximum height of the flange portion 37 relative to the body 2 is a maximum of 7 mm, preferably 5 mm.

In the Fig. 4 shown side adjustment 5 consists of a cylindrical surface 50 which cooperates with a pin 52 which sits in a pin receptacle 54 of the flange 37 and is guided on actuation of an adjusting screw 56 on the inner cylindrical surface 50. By means of the adjusting screw 56, which is mounted in the flange portion 37, the distance to the body edge is adjusted relative to the base plate 46, whereby a lateral adjustment is made possible. The radius of curvature of the cylindrical surface is chosen so that a pivoting of the flange member 37 about an imaginary, located in the body 2; Pivot axis 11 takes place.

It is understood that other mechanical solutions can be realized, wherein it is important that the flange part 37 of the body-side hinge part 4 can be pivoted about a pivot axis 11 located in the body 2.

This solution principle for a lateral adjustment is generally also applicable to multi-joint hinges.

The Fig. 5a and 5b provide a known lateral adjustment device ( Fig. 5a ) compared to the new solution principle. In Fig. 5a It can be seen that the pivot axis 11 of the body-side hinge part 4 is arranged in the body-side hinge part 4 according to the prior art. As a result, in the case of a lateral adjustment, the articulated axle 7 moves away from the door leaf 3 by a larger amount.

How out Fig. 5b can be seen results from the solution according to Fig. 4 a lower positional error of the hinge axis 7 in relation to the door leaf 3 than in the prior art, as an additional advantage, the depth adjustment does not need to be corrected due to the lateral adjustment.

The pin 52 is in the assembled state of the body-side hinge part 4 on the body 2 facing the inner cylindrical surface 50 at. For this purpose, the base plate 46 is connected to the flange 37, wherein the adjusting screw 56 is hooked for the lateral adjustment under the base plate 46. Subsequently, the pin 52 is pressed in the flange portion 37 in the pin receptacle 54, so that the parts are indeed movable relative to each other, but are permanently connected to each other.

The Tiefenverstellplatte 48 is fixedly attached to the body 2.

The depth adjustment device 16 is locked in the delivery state of the hinge 1 in a central position and, if a depth adjustment is necessary to be unlocked. In this case, the base plate with the flange portion 37 can be offset relative to the Tiefenverstellplatte 48 in the depth direction. For this purpose, both the base plate 46 and the flange portion 37 slots 58, 60, 62, 64, so that a depth adjustment can be made. The position of the base plate 46 with the flange portion 37 relative to the Tiefenverstellplatte 48 is set with matched teeth 66, 68 of the base plate 46 and the Tiefenverstellplatte 48 once the three mounting screws 24 are tightened.

In Fig. 6 a possibility of an additional side adjustment is shown, which can be done in the hinge cup 8 of the door-side hinge part 6. For this purpose, the connecting part 14 is provided with an adapter 27, which allows a displacement of the connecting part 14 with the aid of a guided in a slot fastening screw. The adapter 27 has on its underside grooves 28, which may be engaged with the guide means 13, which consists of guide rails, as basically in Fig. 3 shown.

This lateral adjustment can with a height-adjustable hinge 1 with a provided in the hinge cup 8 height adjustment device 10 in addition to the in Fig. 4 and Fig. 5b may be provided 5 shown side adjustment.
