EP1760233A2 - Adjustable hinge - Google Patents

Abstract

Adjustable hinge comprises a sharp-edged protrusion arranged on an adjusting plate (6) and/or on a hinge plate (1, 2) and having a higher degree of hardness than the contacting counter surface of the interacting adjusting plate or hinge plate. Preferred Features: The sharp-edged protrusion is formed as a protruding annular band or matrix or ribbed surface with pyramidal tips. The annular band is arranged on the adjusting plate.

Description

The invention relates to an adjustable hinge according to the preamble of patent claim 1.

Such a hinge is, for example, with the subject of EP 0 991 836 B1 known. In this known hinge, the adjustment in two mutually perpendicular directions is that in the hinge plate in each case a recessed slot is arranged, the surrounding area is provided with a corrugation.

In this slot-like depression engages an adjusting bush, which consists of a disc-shaped upper part of larger diameter, on the underside of an oval collar of smaller diameter is formed. This oval collar engages in the associated oval recording in the hinge plate and also carries a corrugation on its lower side.

Consequently, the corrugation on the underside of the adjusting disc cooperates with the corrugation in the recessed slot in the hinge plate.

To adjust the hinge thus the adjusting disk can be moved in two mutually perpendicular directions in the slot, to then be fixed with a, passing through the adjusting screw.

Such an embodiment has been proven, but is relatively expensive because of the complex shapes for the die-cast part.

Another disadvantage is that the corrugation at the bottom of the slot-shaped receptacle in the hinge plate and the corrugation on the front side of the adjusting are aligned the same.

As a result, one adjusting disk in the slot-shaped recess can only be displaced in one direction and the adjacent adjusting disk in the other slot-shaped configuration can be displaced in the direction perpendicular thereto. Consequently, there is only the possibility to adjust the adjustment disc in the respective slot-shaped recess in a single direction. This limits the setting range.

There is another embodiment of a hinge of the company EMKA has become known, in which round recesses are arranged in the hinge plate of the hinge, at the bottom of a flange is formed with a corrugation of reduced diameter.

The arranged at the bottom of the receptacle corrugations are offset from one another at an angle of 90 °. So there is only the orientation in the one and a direction perpendicular thereto.

The associated Justierscheiben are annular and have a round collar, in turn, corrugations are arranged on the lower front side. These corrugations are formed at an angle of 90 ° to each other.

As a result, when adjusting the hinge when the fastening screw is loosened, the adjusting washer thus has to be rotated in the receiving bore of the hinge plate in such a way that the corrugations of the adjusting disc and the receiving bore of the hinge plate are aligned identically. There are therefore only four different relative positions of the adjusting in the receiving bore of the hinge plate possible, each offset by 90 ° to each other.

This means that the adjusting disk can only be displaced in the longitudinal direction and / or in the vertical direction in the circular recess of the hinge plate and fixed according to the pitch of the corrugation.

This requires that the mutually perpendicular corrugations at the bottom of the adjusting and the bottom of the recess positively engage with each other.

Such a form fit is always desired, because by the total weight of the door and when loosening the fixing screw, it is necessary that the adjusting disc still positively engages in the corrugations, to avoid that the door with the hinge attached to it adjusts to the frame unintentionally ,

Such a form fit is thus only in each case to 90 degrees offset directions with respect to the adjustment and the engagement in the round hole of the hinge plate to achieve.

However, the circular design of the adjusting disk in the EMKA design has the disadvantage that it can rotate by less than 90 ° before or when tightening the fastening screw, and thus the corrugations of the adjusting disk and the receiving bore of the hinge plate can no longer engage with one another in a form-fitting manner.

In the EP 0 991 836 B1 Thus, it could only be adjusted in a single direction in the associated slot, in the EMKA version, the adjusting disk could be adjusted in two mutually perpendicular directions in the round hole of the hinge plate and fixed.

The invention is therefore based on the object, a hinge with adjusting discs of the type mentioned in such a way that the assembly can be performed faster, easier, safer and repeatedly repeatable while adjusting the adjustment disc in any direction in the plane of the hinge plate arbitrarily and positively can be fixed.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that provided on the adjusting disk and / or on the hinge plate at least one sharp elevation has a higher degree of hardness than at least the contact therewith mating surfaces of the cooperating other component, namely the Justierscheibe or the hinge plate.

The advantage here is that the at least one sharp-edged survey digs form fit through their higher degree of hardness in the softer counterpart and thus there formed an embossed annular groove when the hinge screw is screwed, the adjustment to the hinge plate almost arbitrarily in all directions in the plane of the hinge plate is adjustable and thus a fast, easy, safe and repeatable assembly can be performed.

The at least one bump of higher hardness is preferably formed as a self-contained sharp-edged annular collar, or by a plurality of identical or similar pointed bumps (e.g., pyramids) that together form a uniformly or unevenly interrupted ring (circle, ellipse, etc.).

Alternatively, however, these pointed bumps may be distributed over a larger area and may have the form of a "gripper surface" with a plurality of matrix-like pyramids, or with a plurality of cross-section, e.g. triangular ribs.

Furthermore, the soft mating surface into which the at least one pointed elevation penetrates in a form-fitting manner does not necessarily have to be flat and flat, but may also have at least one protrusion or at least one recess from the surface of the mating surface. This at least one elevation or this at least one recess may have any shape in cross section, for example triangular, quadrangular, polygonal, trapezoidal, circular, etc., and may also be present multiple times. A radially arranged plurality of ribs rising from the soft opposing surface and having a triangular cross section is preferred.

In particular, the relatively hard elevations on the adjusting disk and are pressed only by the force when tightening the hinge screw in the softer material of the bottom of the recording of the hinge plate, whereby there corresponding depressions are impressed, which form a positive connection with the surveys. However, the prerequisite is that at least the bottom of the recording of the hinge plate (or only the receptacle or the entire hinge plate) consists of a softer material, as the elevations of the adjusting. In particular, the entire adjustment is made of steel and the entire hinge plate made of zinc die-cast.

1. 1. Der Ringbund wird so ausgebildet, dass er auf einem Kreis von "Spitzen" besteht, die sich nun leichter in das weiche Gegenstück (z. B. Zink-Druckguss-Teil) einkerben. Natürlich kann man auch ganz von einem Ringbund (oder mehrere) abgehen und z.B. die Justierscheibe mit einer sogenannten "Gripperfläche" versehen, nämlich mit pyramidenförmigen Spitzen. Hier handelt es sich aber nicht mehr um ein reines kostengünstiges Drehteil.
2. 2. Z.B. die Justierscheibe besitzt einen Ringbund (oder mehrere) mit höherer Härte. Das weiche Gegenstück (z. B. Zink-Druckguss-Teil) ist jedoch so ausgebildet, dass sich der Ringbund in die weichere Scharnierplatte einschneidet. Dies kann z. B. dadurch erreicht werden, dass die weichere Scharnierplatte ebenfalls mit Erhebungen (bzw. Einkerbungen) versehen wird, die vorzugsweise strahlenförmig angeordnet sind. Die strahlenförmige Ausbildung der Erhebungen (bzw. Einkerbungen) der Scharnierplatte hat den Vorteil, dass die Justierscheibe nicht die Tendenz hat, sich in eine Einkerbung hin zu verschieben, vielmehr sich einfach nur eindrückt.

In order to achieve an improvement of the positive connection by impressing the elevations of the adjusting disk, two structural variants are provided in particular:

1. 1. The collar is formed to rest on a circle of "peaks" that are now easier to indent in the soft counterpart (eg zinc die cast part). Of course, you can also completely from a ring collar (or more) depart and, for example, the Justierscheibe with a so-called "Gripper surface" provided, namely with pyramidal tips. However, this is no longer just a cost-effective rotary part.
2. 2. For example, the adjusting disk has a ring collar (or more) with higher hardness. However, the soft counterpart (eg, zinc die cast part) is designed so that the annular collar cuts into the softer hinge plate. This can be z. B. be achieved in that the softer hinge plate is also provided with elevations (or notches), which are preferably arranged radially. The radial design of the elevations (or notches) of the hinge plate has the advantage that the adjusting disc does not have the tendency to move in a notch out, but just just pushes.

If the collar of the adjusting disc engages in an associated annular groove embossed by the annular collar at the bottom of the recess of the hinge plate, you can rotate the adjusting disc in any direction and still remain the form-fitting and the positive fastening between the adjusting and the hinge plate maintained.

This has the significant advantage that with slightly tightened adjustment (eg., When loosening) always the positive engagement with the hinge plate is maintained and there is no risk that the entire door sags together with the hinge from the frame, which in the other Embodiments in particular in the embodiment of the company EMKA was the case.

So you have in any mounting hole of the hinge plate all degrees of freedom of the displacement of the adjusting disk to the hinge plate in all directions of the plane of the hinge plate, and a completely free possibility of rotation of the adjustment to the hinge plate, while in the prior art of EP 0 991 836 B1 was not the case.

In the case of the EMKA design, the adjustment disk always had to be turned by hand during the adjustment procedure so that the corrugation on the underside of the adjustment disk engaged with the corrugation in the region of the recess in the hinge plate in order to achieve positive locking, resulting in a complicated lengthy and not always form-fitting secure mounting led, which also could not be done as often as possible, since the corrugations could take damage in a non-optimal assembly.

This is not necessary in the invention with the annular collar, because in the invention in any rotational position of the adjusting a positive locking, for example, the at least one, arranged on the underside of the adjusting ring, ring collar takes place in the impressed by the annular collar at the bottom of the recess.

The invention is not restricted to the fact that at least one annular collar is arranged on the adjusting disk. It should also be protected in the context of the inventive idea, the mechanical reversal, that is arranged on the hinge plate of at least one annular collar. Also, several annular collars should be possible on the adjusting disk or on the hinge plate, which then interact with a respective imprinted by the annular collar annular groove on the other part. Also, combinations thereof should be possible, so that in each case at least one annular collar and at least one embossed annular groove is present on the adjusting disk and on the hinge plate. It is always important only that the adjusting disc can be adjusted to the hinge plate and after the assembly at least one annular collar engages positively in an impressed during assembly by the annular collar annular groove.

The invention is therefore not limited to the arrangement of a single (as sharp as possible) annular collar on the bottom surface (front side) of the adjusting. It can also be present several, in particular concentric annular collars, each of which is formed sharp-edged.

The invention preferably relates to a round running, over the entire circumference extending, continuous annular collar on the front side of the adjusting disk. However, the invention is not limited thereto. It can also be provided that the annular collar is arranged distributed only in places on the circumference.

Likewise, the annular collar can be replaced by punctiform or prism-shaped extensions, which are also distributed only on an equal diameter on the circumference of the end face of the adjusting disc.

Incidentally, it has also been pointed out at the outset that necessarily not only a single annular collar can be present, but that a plurality of annular collars having a different diameter can be arranged on the end face of the adjusting disc.

It is particularly advantageous that the entire adjusting disk can now be designed as a simple rotary part and the previously mentioned, relatively sharp-edged annular collar can now be formed as a turned collar on the adjusting disk.

Thus, the adjustment can be produced as a cost-effective steel turned part.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are the drawings and their description further features and advantages of the invention.

In Figures 1, 2 and 3, the hinge consists of two mutually pivotally mounted hinge plates 1, 2, each forming complementary to each other approaches 3, 4, which are penetrated by a central bore 5, which is filled by a pin, not shown. It is therefore a single-pin hinge.

In the region of each hinge plate 1, 2 in this case two spaced receptacles 7 are arranged for the associated adjustable recording of adjusting discs 6.

FIG. 1 shows the adjusting disks 6 already used in the receptacles 7.

It can be seen that, regardless of the maximum possible shift position of each adjusting disc 6 in the receptacle 7, always the entire receptacle 7 is covered.

For purposes of identification, the perimeter of the receptacle 7 is bounded by a perimeter rim 8 of larger dimension. FIG. 3 shows that a receptacle 7 embedded in the hinge plate 1 consists of the above-mentioned surrounding rim 8, which is approximately square and serves only optical purposes. He has with respect to the function of the adjustment no further task. The perimeter edge 8 is slightly elevated above the surface of the respective hinge plate 1, 2. In the area of this Umfassungsrandes 8 thus sits the adjusting disc 6 with a circular collar 12 of increased diameter. This Umfassungsrand 8 may also be omitted in another embodiment.

The diameter of the collar 12 of the adjusting disc 6 is chosen so that in any shift position, the inner diameter of the receptacle 7 is always covered.

The profile of the receptacle 7 is square according to Figure 5, wherein this square has rounded corners. This is evident from the comparison of FIG. 3 with the approximately square wall 9 shown there with the illustration in FIG. 5, where this wall 9 is also shown.

The wall 9 of larger diameter is perpendicular to a bottom 10 of reduced diameter, wherein in the region of the bottom 10 of the receptacle 7 which is impressed by the adjusting disk 6 corrugation 22 is arranged.

Incidentally, FIG. 6 shows the slightly raised surrounding rim 8, which is designed to be raised in relation to the other surface of the hinge plate 2.

FIG. 4 shows a partial view of how two equally sized annular grooves 16, 18 in the form of corrugation 22 have been embossed into the bottom surface of the base 10 by the adjusting disk 6.

The sharp-edged annular collar 15 of the adjusting disk 6 is otherwise formed in the region of the end face 14 of a bushing 13 of smaller diameter, the bushing 13 having a smaller diameter than the bushing 13 surrounding the collar 12 comparatively.

In Figure 3 is still shown that the hinge plates 1, 2 in their respective receptacles 7 a central, approximately circular through-opening 11th has, and that the adjusting disc 6 has an approximately circular central passage opening 24, through which through openings 11, 24 a mounting screw, not shown, passes through, for fastening the hinge between two mutually pivotable parts, eg furniture parts.

FIGS. 8 and 9 now show a modified embodiment of the hinge according to the invention, with a modified surface on the bottom 10 of the receptacle 7 (for the adjusting disks 6) in the hinge plates 1, 2. The radial elevations 17 shown there have a common imaginary one Center in the middle of the receptacle 7. These radial elevations 17 are formed approximately triangular in cross section and lie in a plane which is parallel to the plane of the hinge 2.

In another embodiment, the projections 17 may have a different cross-sectional shape, e.g. round, oval, square, polygon etc .. Also, the radial elevations 17 do not necessarily have a common center, but can intersect in another imaginary point. Also, the surveys in another embodiment could not intersect and run parallel to each other.

It is only important that the sharp-edged annular collar 15 of the adjusting washer 6 when screwing the fastening screw (not shown) digs into the elevations 17 positively and thus leaves an embossed circular corrugation 22 according to Figures 4 and 5.

Figures 10 and 11 now show a comparison with Figure 9 modified version of the adjusting disc 6 with annular collar 15 in the form of the adjusting disc 19 which has instead of the annular collar 15 on the entire end face 20 of the collar 21 pyramidal tips 23.

In another embodiment, however, the end face 20 of the collar 21 of the adjusting disc 19 only partially with the pyramidal tips 23rd be provided, which can also be arranged in the form of a ring or a plurality of rings.

It is also important here only that the pyramidal tips 23 of the adjusting washer 6 when screwing the fastening screw (not shown) dig into the surface of the bottom 10 of the receptacle 7 of the hinge plates 1, 2 positively and thus impressed corrugations (not shown) leaves.

Also, of course, a combination of the embodiments of Figures 8/9 and 10/11 are used, so that the adjusting disk 19 is inserted into the receptacle 7 of Figures 8/9 and the pyramids 23 dig into the beam elevations 17 form fit, when the fastening screw (not shown) is tightened.
