Description

The invention relates to a door or window hinge with two hinge parts that are operatively connected to one another and rotatable about a common hinge axis, at least one door or window-side first hinge part having a plate-like section which can be inserted into a groove on the front side of the door or window Holding piece cooperates firmly and releasably connectable, the plate-like section being aligned in an imaginary plane parallel to the hinge axis and being adjustable in relation to the holding piece in an imaginary plane at right angles to the plane of the plate-like section, and an adjusting screw being screwable into at least one thread of the holding piece, wherein an axis of the adjusting screw runs perpendicular to the plate-like section, wherein a head of the adjusting screw is arranged between an intermediate piece and the plate-like section by means of a clamping device, which from one side of a Kl emmbolzen and is formed from the other side from a sleeve pressed onto the clamping bolt and which applies force to the plate-like section and the intermediate piece from opposite sides and thus holds them together.

One such hinge is from the DE 10 2007 028 218 B3 known. This hinge offers several adjustment options in different directions. For an adjustment of the hinge perpendicular to the plate-like section and perpendicular to the hinge axis, an adjusting screw is provided, the screw head of which is arranged between the plate-like section and an intermediate piece which is in turn connected to the holding piece. In order to hold the plate-like section and the intermediate piece together, screws are provided which pass through openings in the plate-like section and are screwed into the thread of the intermediate piece or into threaded sleeves formed on the intermediate piece. The plate-like section and the intermediate piece are thus firmly fixed. If you want to move the plate-like section and the intermediate piece for the purpose of adjustment parallel to the plate-like section and perpendicular to the hinge axis against each other, the screws that hold the plate-like section and the intermediate piece together must first be loosened. Only then can the hinge be adjusted in the named direction by means of a further adjusting screw which is arranged perpendicular to the adjusting screw discussed above. A height adjustment of the hinge, that is to say an adjustment parallel to the plate-like section and parallel to the hinge axis, can be carried out by adjusting a second hinge part.

The prior art hinge described thus has adjustment options along three spatial coordinates arranged perpendicular to one another, so that a practicable solution is offered here. However, by fixing the plate-like section on the intermediate piece by means of screws, an adjustment of the hinge parallel to the plate-like section and perpendicular to the hinge axis is only possible if two screws are loosened beforehand. Then an adjusting screw can be operated, whereupon the screws have to be fixed again.

The invention is based on the object of providing a door or window hinge which is equipped with improved adjustment elements.

This object is achieved with the features of the independent claim.

Advantageous embodiments of the invention are given in the dependent claims.

The invention is based on the generic door or window hinge in that the intermediate piece and the plate-like section can be displaced relative to one another by means of a rotary device by means of an eccentric, the eccentric consisting of at least two cylinder sections displaced in their axis and having a bolt-like shaft which is pressed into a sleeve which is designed to be displaceable in an axial direction of the sleeve in a bore in the holding part.

The plate-like section and the intermediate piece are not firmly screwed to one another, but the components are held together with a clamping device consisting of a clamping bolt and sleeve. This clamping or pressing together of the plate-like section and the intermediate piece can be used to hold a screw head which is assigned to a screw for adjusting the hinge perpendicular to the plate-like section and perpendicular to the hinge axis. Furthermore, the plate-like section and the intermediate piece are not screwed to one another, so there is no need to loosen any screws that are screwed into the intermediate piece in order to adjust the hinge parallel to the plate-like section and perpendicular to the hinge axis. The attached sleeve can, for example, be pressed on or screwed on.

It is particularly preferred that the head of the adjusting screw has little play between the intermediate piece and the plate-like section in the direction of the axis of the adjusting screw or is kept free of play. This allows the hinge to be adjusted very precisely, since due to the lack of play or the freedom from play of the screw head mounting, a specific screw rotation corresponds exactly to a specific adjustment of the hinge perpendicular to the plate-like section and perpendicular to the hinge axis.

In the present invention it is provided that the intermediate piece and the plate-like section can be displaced relative to one another by means of a rotating device by means of an eccentric. An eccentric is able to convert a rotary movement into a linear movement. The adjustment of the hinge parallel to the plate-like distance and perpendicular to the hinge axis can thus be carried out by simply rotating the eccentric, namely by moving the plate-like section and the intermediate piece against one another.

It is provided that the eccentric consists of at least two cylinder sections which are shifted relative to one another in their axis.

Furthermore, the eccentric has a bolt-like shaft which is pressed into a sleeve which is designed to be displaceable in an axial direction of the sleeve in a bore in the holding part. The axial displaceability of the sleeve in the bore in the holding part ensures that an adjustment of the hinge perpendicular to the holding part and perpendicular to the hinge axis is not hindered by the eccentric. Due to the preferably play-free mounting of the sleeve in the holding part, a precise displacement of the hinge takes place parallel to the plate-like section and perpendicular to the hinge axis when the eccentric rotates.

It is particularly advantageous that the clamping bolt and the eccentric are designed as one component. Even if for clamping plate-like section and

Intermediate piece on the one hand and the setting of the relative position of these two components on the other hand, in principle two different components can be used, it is particularly useful to combine these two functions in one component.

The door or window hinge according to the invention is developed in a particularly advantageous manner in that the adjusting screw has an internal engagement with the head which has a smaller outer diameter than one that is aligned with the adjusting screw provided adjustment opening in the plate-shaped section. This enables access to the adjusting screw by means of a tool.

Furthermore, it can be provided that a second hinge part has an adjusting bolt which is aligned and adjustable in the direction of the hinge axis and which can be firmly connected to the plate-like section. The adjustment of the hinge parallel to the hinge axis and parallel to the plate-like section is thus implemented in the second hinge part, which advantageously limits the required complexity of the first hinge part.

In this context it can usefully be provided that the adjusting bolt is held at one axial end by an axially acting screw, the adjusting bolt being adjustable by turning the axially acting screw. An adjustment of the hinge parallel to the hinge axis and thus also parallel to the plate-like section can thus be achieved very conveniently by simply turning an axially acting screw.

In a particularly useful way, it can be provided that the axially acting screw can optionally be screwed into both ends of the second hinge part. As a result, the hinge can be used in both vertical orientations, in other words for doors or windows with right-hinged or left-hinged hinges.

The invention will now be explained by way of example with reference to the accompanying drawings using a particularly preferred embodiment.

In the following description of the drawings, the same reference symbols designate the same or comparable components.

Figure 1 shows a perspective view of a hinge 1 according to the invention. Figure 2 shows a plan view perpendicular to the hinge axis 2 of the first hinge part 3 of a hinge 1 according to the invention. Figure 3 shows a partially sectioned side view of a hinge 1 according to the invention. Figure 4 a perspective partial representation of the first hinge part 3. The door or window hinge 1 shown comprises a first hinge part 3 and a second hinge part 4. The first hinge part 3 and the second hinge part 4 are connected to one another via a connecting plate 23. The second hinge part 4, which is usually attached to a door or window frame by means of fastening pins 24, has two lateral bearings 25, 26 and a central bearing 27. The bearings 25, 26, 27 are arranged on an adjusting bolt 22, the elongated Extension of the hinge axis 2 defines. The central bearing 27 is firmly connected to the adjusting bolt 22 via a grub screw 28, while the adjusting bolt 22 can rotate with respect to the lateral bearings 25, 26 during the pivoting of the door or the window.

The first hinge part 3 comprises a holding piece 9 with which it can be inserted into a groove of a door or a window. Furthermore, the first hinge part 3 has a plate-like section 8, an intermediate piece 14 and several fastening and setting elements. Based on Figure 3 the structure of the first hinge part 3 can be clearly seen. The plate-like section 8 and the intermediate piece 14 are held together by means of clamping bolts 13 on which a sleeve 18 is placed. The clamping bolt 13 and the sleeve 18 together form a clamping device 5. The intermediate piece 14 and the plate-like section 8 are designed so that they can hold a head 12 of an adjusting screw 11, this head 12 with as little play as possible or even free of play from the intermediate piece 14 and the plate-like portion 8 is received. The plate-like section 8 has slot-like adjustment openings 20 through which the head 12 of the adjustment screw 11 can be reached by means of a tool, in the present example with an Allen key. The so held together by the clamping bolts 13 and sleeves 18 An arrangement made up of a plate-like section 8, an intermediate piece 14 and adjusting screws 11 is connected to the holding piece 9 in that the adjusting screw 11 is screwed into a thread 10 of the holding piece 9. This fastening of the arrangement of plate-like section 8, intermediate piece 14 and adjusting screws 11 with the holding piece 9 is not hindered by the clamping bolts 13 or the sleeves 18 placed thereon, since the sleeves 18 can be displaced in the bores 19 of the holding piece 9 provided for this purpose and thus a further one Provide guidance. The entire arrangement described is then fixed by means of a fixing screw 6. The fixing screw 6 rests with its screw head on the plate-like section, it passes through openings in the plate-like section 8 and the intermediate piece 14, the opening in the plate-like section 8 being designed as an elongated hole 7, and it is in a thread of the holding piece 9 screwed in. Since the elongated hole 7 in the plan view according to Figure 2 is covered by the screw head of the fixing screw 6, this is shown here by a broken line.

The clamping device 5, which has a bolt-like shaft 17 and a sleeve 18 connected to it, has an eccentric 16 at the end facing away from the sleeve 18 as a further special feature. The entire clamping device 5 with eccentric 16 in the present example thus comprises two cylindrical sections, namely the bolt-like shaft 17 and the eccentric 16, the axes of which are parallel and offset from one another, and the sleeve 18, which is arranged on the side of the clamping device facing away from the eccentric. The eccentric 16 rests with a collar on the plate-like section, and it is guided through an elongated hole 29 of the plate-like section. The bolt-like shaft 17 attached to it passes through an opening in the intermediate piece 14. The collar of the eccentric 16 and the sleeve 18 of the clamping device 5 apply the opposing force components which hold the plate-like section 8 and the intermediate piece 14 together.

The hinge is adjusted perpendicular to the plane of the plate-like section 8 and perpendicular to the hinge axis 2 in accordance with the assembly of the first hinge part 3 described above. A tool is guided through the adjustment opening 20 into the head 12 of the adjustment screw 11. By screwing the adjusting screws 11 more or less far into the thread 10 of the holding piece, the desired setting of the hinge takes place. The sleeves 18 slide as guides in the bores 19 of the holding piece 9 provided for this purpose.

If the hinge is to be adjusted parallel to the plane of the plate-like section 8 and perpendicular to the hinge axis 2. The eccentrics 16 are used for this. The eccentrics 16 are in Figure 2 and in Figure 3 shown in their middle position. If the eccentric 16 is rotated in the "+" or "-" direction by means of a rotating device 15, the plate-like section 8 shifts relative to the intermediate piece and to the holding piece 9, whereby the hinge can be adjusted in the direction mentioned. The fixing screw 6 is preferably loosened before this setting process, as a result of which the friction between the plate-like section 8 and the intermediate piece 14 is reduced. After the adjustment process, the fixing screw 6 can be tightened again.

Figure 5 shows a partially sectioned side view of a hinge 1 according to the invention. Figure 6 shows a partially sectioned plan view in the direction of the hinge axis 2 of a hinge 1 according to the invention. The second hinge part 4 has an adjustment bolt 22 which has already been mentioned above and which serves as an axis for two lateral bearings 25, 26 and a central bearing 27 and defines the hinge axis 2. The adjusting bolt 22 is connected to the central bearing 27 via a grub screw 28 (see Figure 1 ) connected. For this purpose, the adjusting bolt 22 has a constriction 30. The central bearing 27, which is connected to the first hinge part 3 via the connecting plate 23 and rotates together with the door, is equipped with bushings 31, 32, 33, 34 which can be displaced relative to steel rings 35, 36 of the lateral bearings 25, 26 are. The steel rings 35, 36 of the side bearings 25, 26 are displaceable relative to the side bearings 25, 26. In order to prevent the steel rings 35, 36 from rotating in the lateral bearings 25, 26, they are not completely round, but have one or more flattened areas 37.

Since the adjusting bolt 22 is thus axially displaceable relative to the lateral bearings 25, 26, it must be fixed in its axial position. This takes place via an axially acting screw 38 screwed into the lateral bearing 26 at the end, preferably a grub screw, via which the hinge can also be adjusted in the direction of the hinge axis 2. It is possible to completely unscrew the axially acting screw 38 from the side bearing 26, the adjusting bolt 22 the other way around than in FIG Figure 5 to be arranged shown and then screw the grub screw 38 into the other side bearing 25. In this way, a left-hand hinge can be produced from a right-hand hinge and vice versa.

The features of the invention disclosed in the above description, in the drawings and in the claims can be essential for realizing the invention both individually and in any combination within the scope of the appended claims.
