Description

Hinge for doors, windows or the like.

The invention relates to a hinge for doors, windows or the like, with at least one hinge piece associated with the frame that can be fixed to a frame, with at least one hinge piece associated with the sheet that can be fixed to a sheet , with a hinge bolt that is inserted into the hinge pieces and joins them together so that they can swing around an articulation axis, said bolt being able to be fixed on the hinge piece associated with the blade, so that cannot rotate around the articulation axis with respect to the hinge piece associated with the blade or in the direction of the hinge axis, and with a threaded bushing surrounding the hinge bolt, it has an external thread that is applied to a thread complementary interior provided in the hinge piece associated with the blade and with its lower front face rests directly or indirectly on the hinge piece associated with the frame.

A hinge of this type is known from DE 297 13 254 U1. In this hinge, the threaded bushing, in its lower area that protrudes from the hinge piece associated with the blade, comprises a turning drive flange having drive recesses in which a key for slotted nuts can be placed for driving rotation intended to adjust the hinge piece associated with the blade in the direction of the articulation axis.

In this hinge it is unfavorable that the length of the area of the threaded bushing protruding from the hinge piece associated with the blade must have a certain minimum measure for the placement of the key for slotted nuts, whereby the distance between the piece of hinge associated with the leaf and the hinge piece associated with the frame or between its articulation pieces in the direction of the articulation axis is precisely this minimum distance. Therefore, this hinge gives a broken visual impression. In addition, the visual impression is further disturbed by the drive recesses. Finally, the area between the two articulation pieces is difficult to clean, so that dirt accumulates here easily, which can lead to increased wear and noise during the hinge operation.

From document DE 200 07 759 U1 a door or window hinge is known which has a hinge piece associated with the frame and a hinge piece associated with the leaf which are articulated together with each other by means of a hinge bolt. This hinge further comprises a threaded bushing that is arranged rotatably coupled to the hinge bolt, but movable in the direction of the articulation shaft. This threaded bushing comprises a lower area that has the outer thread and an upper area without a thread, the outer diameter of the area without thread corresponding approximately to the central diameter of the outer thread. The zones are provided on their associated sides, respectively, with telescopic necks that protrude axially through which the two zones link together.

The lower part of the threaded bushing comprising the outer thread is connected in rotation to the hinge bolt. A height adjustment can therefore be made by turning the hinge bolt.

In order to prevent a tilt of the door or window leaf from leading to a displacement of the hinge piece associated with the leaf with respect to the hinge piece associated with the frame, a captive screw is provided which is mounted in a threaded bore in the piece of hinge associated with the blade and can rotate through a hole in the bottom of the threaded bushing against the hinge bolt. In order to consider a relative height graduation between the hinge bolt and the lower part of the threaded bushing that is necessary for adjustment, in the lower part there are provided four holes arranged 90 ° respectively, which are made as elongated holes. These four elongated holes should be sufficient for the usual thread steps to achieve a sufficiently fine height graduation.

In this hinge it is unfavorable that the possibility of graduation in height cannot be done without steps. In addition there is a danger that after making the adjustment by screwing the captive screw for fixing one of the holes is not found, so that the threaded bushing can be damaged or even destroyed.

The invention is therefore intended to develop a hinge that is better in regard to the aforementioned drawbacks.

This object is carried out by the hinge described in claim 1.

According to the invention, the threaded bushing is rotatably coupled with the hinge bolt, but arranged movable in the direction of the articulation axis. By this measure it is no longer necessary to provide a twist drive flange in the threaded bushing, but the rotation movement can be introduced through the hinge bolt. For this, it can have at one front end means for the placement of a turning tool, for example a screwdriver or a hexagonal head wrench. Since the hinge bolt is arranged movable in the direction of the articulation axis, the hinge piece associated with the blade can be adjusted in the direction of the hinge axis, that is vertically, without the hinge bolt moving relative to the hinge piece associated with the frame that houses it. After the adjustment process, the hinge piece associated with the blade can be fixed in the desired position, the hinge bolt being fixed so that it can no longer rotate with respect to the hinge piece associated with the blade.

The turning coupling between the threaded bushing and the hinge bolt can be achieved if the hinge bolt has a longitudinal groove in which a projection of the threaded bushing that projects radially inwards is applied.

In the hinge according to the invention, the threaded bushing comprises a lower zone having the outer thread and an upper area without a thread, the outer diameter of the non-threaded area corresponding approximately to the central diameter of the outer thread. The guide function for the hinge bolt produced by the threaded bushing is ensured by this measure, without it being necessary to mount the threaded bushing, screw it along its entire length into the internal thread provided in a recess of the workpiece. of hinge associated to the leaf. This reduces the time required for a basic mounting of the threaded bushing to a central position.

The area that has the external thread and the area without thread are formed, respectively, by separate bushing pieces. Between the bushing pieces, a coupling element is provided for fixing the two bushing pieces in the direction of the articulation shaft, which is arranged in rotation in connection with the hinge piece associated with the blade. The hinge bolt can be fixed to the hinge part associated with the blade, then it can be carried out in the area of the coupling element, achieving a possibility of adjustment without steps, since the lower sleeve piece is rotatable with respect to the coupling part in around the axis of articulation. Also by this measure it is avoided that during the basic assembly of the threaded bushing or in the adjustment process the area without thread rotates with friction in the thread passages of the internal thread of the hinge piece associated with the blade, which could lead at an elevation of wear of the internal thread.

The coupling element preferably comprises at each front end coupling means that can be brought to be applied to one of the bushing pieces, respectively. The basic mounting of the threaded bushing is carried out, for example, so that the part provided with the outer thread is screwed into the housing to the central position, the retaining element is inserted from above in the recess and finally the bushing piece without Thread is pressurized from above with a pressure such that the coupling means is applied to the complementary coupling means.

The coupling means preferably comprise a peripheral retention projection in a plane transverse to the articulation axis.

The complementary coupling means preferably have a peripheral retention slot made complementary to the retention boss. The retention projection and the retention groove have dimensions such that they can be applied to overcome elastic deformation forces.

Especially preferred is a refinement of the coupling element comprising a part that can be taken to be applied to a bushing piece and another piece that can be taken to be applied to the other bushing piece. In other words, the coupling element itself is made of two pieces. Due to this measure it is possible first of all to take the corresponding part of the coupling element to be applied with the corresponding bushing piece and then insert the corresponding bushing piece together with the coupling piece into the housing. Next, it is only necessary to carry out the joining of the two pieces of the coupling element, these parts in turn comprising complementary retention means to each other that can be carried out to be applied.

Especially preferred is an embodiment of the hinge according to the invention, in which the parts of the coupling element comprise extensions extending parallel to the articulation axis and which can be coupled in the direction of the articulation axis by means of a retaining joint .

Especially preferred in this case is an improvement of the hinge according to the invention in which the extensions extend in the hinge piece associated with the leaf in guide grooves in the housing crossed by the hinge bolt and which has the internal thread for The threaded bushing. In this way, it is guaranteed first that the coupling element cannot rotate during the basic assembly or in the adjustment process, thereby preventing a turning moment from being transferred to the threaded sleeve piece.

Furthermore, this embodiment allows the diameter of the housing between the guide grooves to be chosen so that it is only slightly larger than the outer diameter of the hinge bolt. The inner side surface of the housing thus protrudes up to the outer side surface of the hinge bolt, so that in this area for fixing the hinge bolt after the adjustment is made, a captive screw that rests on a threaded bore can be used. that runs perpendicular to the axis of articulation.

An exemplary embodiment of a hinge according to the invention is shown in fragmentary form. They show:

Fig. 5, the same view as in Fig. 4, but with the threaded bushing in place and with the hinge bolt

placed, but without the representation of the captive screw drawn in Fig. 4 for fixing the

hinge bolt on the hinge piece associated with the blade.

The hinge designated in conjunction with 100 comprises a hinge piece associated with the sheet 1 that the case of a three-piece hinge may be arranged between two hinge pieces associated with the frame not shown in the drawing.

The hinge piece associated with the sheet 1 comprises a fixing piece 2 and an articulation piece 3.

The fixing part 2 is provided with openings 4 with an elongated hole shape and projections 5, so that an arrangement known per se can be used for the adjustment of the blade transversely to the axis of articulation S, that is to say for the horizontal adjustment of The door leaf.

In the articulation piece 3 there is provided a housing 6 having an inner thread 9, both in its lower end zone 7, 8 according to the drawing, and in the upper final area according to the drawing (see Fig. 3).

The final zones 7 and 8 are joined together by a central zone 10, whose inner diameter is only slightly larger than the outer diameter of a hinge bolt 11 that crosses the housing 6. The central zone 10 comprises two opposite guide grooves between yes with respect to the axis of articulation S, as can be recognized in particular in Fig. 4.

In the housing 6 there is provided a threaded bushing designated with 13 as a whole. This comprises a lower part 14 with an outer thread 15 and an upper part 16 without a thread, whose outer diameter corresponds approximately to the central diameter of the lower part 14. Between the lower part and the upper part 14, 16 a coupling element is provided 17 comprising a bottom piece 18 that can be applied to the bottom piece 14 and a piece 19 that can be applied to the top piece 16. The two pieces 18, 19 respectively have a connecting flange 20, 21 which is located in a plane transverse to the axis of articulation S. Both connecting flanges 20, 21 comprise, respectively, a peripheral retention projection 22, 23 which is applied to a peripheral retention groove in the lower or upper part 14, 16 made complementary to the projection of retention and not recognizable in the drawing. The retention projections 22, 23 and the complementary retention grooves have dimensions such that in the direction of the articulation axis S there is a tightening seat between the coupling element 17 and the pieces 14, 16, although the parts 14, 16 they are rotatable around the axis of articulation S with respect to the coupling element 17.

From the connecting flanges 20, 21 extend over the retaining projection 22, 23, respectively, two extensions 24, 25; 26, 27. Extension 24 has a retention housing that can be taken to be applied to a retention projection provided in extension 26. Correspondingly, extension 25 provides a retention projection that can be taken to be applied to a housing of retention in the extension 27. As for the pieces 18, 19 of the coupling element 17, it is therefore the same components but arranged rotated with each other at an angle of 180 ° around the axis of articulation S. The interior surfaces associated with each other from extensions 24, 25; 26, 27 have a radius of curvature adapted to the diameter of the hinge bolt 11. Its outer contour is adapted to the contour of the guide grooves 12, such that the two pieces 18, 19 can be introduced into the housing 6 by introduction of the extensions in the guide grooves and be fixed to each other by means of the retention devices existing at the ends of the extensions. The central area 10 of the housing 6 has a length that is shorter in the maximum adjustment path than the distance of the connecting flanges 20, 21 from each other, so that the coupling element 17 is movable in the direction of adjustment travel of the articulation axis S.

As shown in Fig. 3, the threaded bushing 13 by the coupling of its components through the retaining joints with each other experiences a complete displacement with respect to the hinge piece associated with the blade in the direction of the articulation axis S when lower part 14 is rotated. Due to the introduction of the turning movement, the lower part 14 has an inward radial projection 28 which can be recognized especially in Fig. 5. The projection is adapted to a longitudinal groove of the bolt hinge 11, so that it can be displaced through the lower part 14, but is rotatably connected. For turning the lower part 14 of the threaded bushing 13, it is therefore only necessary to rotate the hinge bolt accordingly. As can be seen in Fig. 4, the hinge piece associated with the leaf 1 has a threaded bore 29 that extends perpendicularly to the articulation axis S, which is arranged approximately in the center of the longitudinal extension of the articulation piece. 3 of the hinge piece associated with the leaf 1 and extends outside the guide grooves 12 to the central area 10. The threaded bore 29 serves to accommodate a captive screw 30 with which a seat can be produced. tighten between the hinge piece associated with the leaf 1 and the hinge bolt 11. This tightening seat is necessary to prevent that after the vertical adjustment of the leaf, the threaded bush 13 can rotate with respect to the hinge piece associated with the sheet, as this would lead to a mismatch. So that the captive screw 30 is also an effective stop against a violent expulsion of the hinge bolt in the direction of the articulation axis S and thus assures a break against a theft with fracture, a recess is provided in the hinge bolt 31 whose length is chosen so that an extension of the hinge bolt is possible in the hinge piece associated with the blade in the maximum adjustment path. The limit surfaces 32, 33 of the radially projecting hinge bolt constitute stops for the hinge bolt on the stud 30.
