Description

The invention relates to a hinge for doors, windows or the like, with at least one frame hinge that can be secured to the frame, with at least one hinge that can be secured to the leaf with a hinge part that enters and connects these hinge parts with each other with the possibility of rotation around the hinge axis with a loop finger, which is made with the possibility of fixing in the hinge loop part from rotations around the hinge axis relative to the hinge loop part and in the direction the hinge axis, and with the surrounding threaded pin and the threaded sleeve having an external thread, which enters the mating internal thread provided in the hinge loop part and rests directly or indirectly on the frame loop part with its lower end face.

A loop of this kind is known from DE 29713254 U1. In this loop, the threaded sleeve on its lower protruding from the sash loop part of the region contains a rotationally driven flange, which has actuating recesses in which a hook key can be mounted to rotate in order to align the hinge loop in the direction of the hinge axis.

The disadvantage in the case of such a loop is that the length of the threaded sleeve protruding from the casement hinge portion for installing the hook wrench must have a certain minimum value, as a result of which the distance between the casement hinge part and the frame hinge part and accordingly between their hinge parts in the direction of the hinge axis is precisely this minimum value. Therefore, this loop gives an intermittent optical appearance. Further, the optical appearance is further spoiled by executive recesses. Finally, the area between both hinge parts is poorly cleaned, so that dirt can easily accumulate, which can lead to increased wear and noise during operation of the loop.

From EP 1149975 A2, a hinge for doors or windows is known which has a frame hinge part and a hinge hinge part that are pivotally connected to each other by means of a loop finger. This loop also includes a threaded sleeve that is rotatably coupled to the loop pin, but is biased in the direction of the hinge axis. This threaded sleeve includes a lower region having an external thread and an upper thread-free region, the outer diameter of the thread-free region approximately corresponding to the inner diameter of the external thread. These regions on their sides facing each other are provided with an axially protruding telescopic extension, whereby these two regions enter each other.

The lower threaded sleeve region including the external thread is rotatably connected to the loop finger. Thus, the height adjustment can be carried out by turning the loop finger.

To prevent such a situation when the rotation of the door or window sash leads to the rearrangement of the hinge hinge relative to the frame hinge, a countersunk screw is provided, which is installed in the threaded hole in the hinge hinge and is rotatable through the hole in the lower part of the threaded sleeve in the hinge direction finger. In order to take into account the height adjustment required for alignment, between the loop pin and the lower part of the threaded sleeve on the lower part there are four holes 90 ° offset, which are made in the form of oblong holes. These four holes should be sufficient to obtain a sufficiently thin stepped arrangement of elevation levels during normal thread lifting.

The disadvantage of such a loop is that the possibility of rearrangement in height cannot be carried out steplessly. Moreover, there is a danger that after the adjustment is made, when screwing in the countersunk screw to fix one of the holes is unattainable, as a result of which the threaded sleeve may be damaged and even break.

Therefore, the basis of the invention is the task of creating a loop that eliminates these disadvantages.

This problem is solved through the loop presented in paragraph 1.

According to the invention, the threaded sleeve is rotationally engaged with the loop finger, however, it is positioned to bias in the direction of the hinge axis. As a result of this measure, it is no longer necessary to provide a rotationally actuated flange on the threaded sleeve, and the rotational movement can be introduced through the loop finger. To do this, the loop finger may have on the end located on the end side means for mounting a rotary tool, for example a screwdriver or an Allen key. Since the hinge pin is biased towards the hinge axis, the hinge hinge portion can be aligned in the direction of the hinge axis, i.e. vertically, without the need for vertical movement of the loop finger relative to the receiving frame loop part. After the adjustment process, the sash loop can be fixed in the desired position by fixing the loop finger from further turns relative to the sash loop.

Rotational engagement between the threaded sleeve and the loop finger can be achieved due to the fact that the loop finger has a longitudinal groove into which the protrusion of the threaded sleeve extends radially inward.

In a loop according to the invention, the threaded sleeve includes a lower external threaded region and an upper threaded region, the outer diameter of the threaded region approximately corresponding to the inner diameter of the external thread. The guide function for the loop finger realized by means of the threaded sleeve is provided on the basis of this measure without having to screw the entire length into the internal thread provided in the receiving hole of the casement loop for mounting the threaded sleeve. As a result, the time required for the main installation of the threaded sleeve to the middle position is reduced.

The threaded region and the threaded region are respectively formed from separate parts of the sleeve. A coupling element is provided between the parts of the sleeve for fixing both parts of the sleeve in the direction of the hinge axis, and this coupling element is located without the possibility of rotation in the hinge hinge part. Then, the loop finger can be installed in the hinge hinge part in the area of the engaging element during stepless adjustment, since the lower part of the sleeve is rotatable relative to the engaging part around the hinge axis. Also, as a result of this measure, the threadless region is rotated idle during the main installation of the threaded sleeve or during alignment when grinding to the internal threads of the sash loop, which could lead to increased wear of the internal thread.

The engaging member preferably at each end end includes engaging means that are adapted to engage with engaging mating means on a corresponding one of the parts of the sleeve. In this case, the main installation of the threaded sleeve is carried out, for example, due to the fact that the part provided with an external thread is screwed into the inlet hole to the middle position, the stop element is inserted into the inlet hole, and finally, the threaded part of the sleeve is pressed into the inlet hole from above the pressure that the clutch means mesh with the counter clutch means.

Advantageously, the matching means includes a locking protrusion circumferential in a plane perpendicular to the hinge axis of the plane.

In such a case, the coupling means preferably have a circumferential locking groove in response to the locking protrusion. The locking protrusion and locking groove are designed in such a way that they can engage when overcoming elastic deformation forces.

Particularly preferred is the improvement of the engaging member, which includes a part adapted to engage with one part of the sleeve and adapted to engage another part of the sleeve. In other words, the coupling element itself is made up of two parts. Based on this measure, it is possible to first engage the corresponding part of the coupling element with the corresponding part of the sleeve, and then introduce the corresponding part of the sleeve together with the coupling part into the receiving hole. In this case, it is only necessary to connect both parts of the coupling element, for which these parts, in turn, include reciprocal to each other, configured to engage locking means.

Particularly preferred is a loop according to the invention in which portions of the engaging element include extensions extending parallel to the hinge axis, which are adapted to engage / join in the direction of the hinge axis by means of a locking connection.

In addition, it is particularly preferred to improve the hinge according to the invention, in which the extensions extend into guide grooves made in a pierced loop finger having an internal thread for the threaded sleeve of the receiving hole in the hinge hinge. Thus, first of all, it is guaranteed that the coupling element during the main installation and during the adjustment process cannot rotate idle - i.e. rotate independently, which prevents the transmission of torque to the threadless part of the sleeve.

Further, this embodiment ensures that the diameter of the receiving hole between the guide grooves can be selected so that it is only slightly larger than the outer diameter of the loop finger. Thus, the inner side surface of the receiving hole extends up to the outer side surface of the loop pin, so that in this area a countersunk screw located in the threaded hole extending across the hinge axis can serve to fix the loop pin after adjustment.

An example implementation of the loop according to the invention - in parts - is presented in the drawings, on which:

figure 1 - sash loop part of an example implementation in perspective detail view;

figure 2 - located inside the sash loop part of the loop of the finger;

figure 3 - the same casement hinge part in the state after the main installation, with strokes represented by invisible lines;

figure 4 is a view according to figure 3 from below without an inserted threaded sleeve, and

5 is the same view as in FIG. 4, but with an inserted threaded sleeve and an inserted hinge pin, but without the image of the countersunk screw shown in FIG. 4 for fixing the hinge pin in the hinge hinge part.

The hinge indicated in the drawings as a whole by 100 includes a hinge hinge part 1, which in a three-hinge hinge may be located between two frame hinges not shown in the drawings.

The hinge hinge part 1 includes a mounting part 2 and a hinge part 3.

The fixing part 2 is provided with holes 4 and extensions 5 made in the form of a longitudinal groove, so that the system known per se can be used to align the leaf perpendicular to the hinge axis S, i.e. for horizontal adjustment of the door leaf.

In the hinge part 3, a receiving hole 6 is provided, which, both at its lower end according to the drawing and the upper end region 7, 8 according to the drawing, has an internal thread 9 (see Fig. 3).

The end regions 7 and 8 are connected to each other by means of a central region 10, the inner diameter of which is only slightly larger than the outer diameter of the loop pin 11. The central region 10 includes two guide grooves 12 opposite each other with respect to the hinge axis S , as can be seen, in particular, in figure 4.

A threaded sleeve, generally indicated at 13, is provided in the inlet 6. It includes a lower part 14 with an external thread 15 and a threadless upper part 16, the outer diameter of which approximately corresponds to the inner diameter of the lower part 14. Between the lower and upper parts 14, 16 there is a coupling element 17, which includes a lower engaging with the lower part 14, part 18 and the part 19 engaged with the upper part 16. Both parts 18, 19 have a connecting flange 20, 21, respectively, which lies in a plane perpendicular to the hinge axis S. Both connecting flanges 20, 21 include, respectively, a circumferential locking protrusion 22, 23, each of which in the lower or upper part 14, 16 is engaged with the circumferential locking groove that is invisible in the drawings and made in response to the locking protrusion. The locking protrusions 22, 23 and the locking grooves corresponding thereto are selected in such a way that a clamping fit is made in the direction of the hinge axis S between the coupling element 17 and the parts 14, 16, however, the parts 14, 16 relative to the coupling element 17 are rotatable around the hinge axis S.

Two extensions 24, 25 extend from the connecting flanges 20, 21 on the opposite side of the locking protrusion 22, 23; 26, 27. Continuation 24 has a locking slot, which engages with a locking protrusion provided on extension 26. Accordingly, a continuation protrusion is provided on continuation 25, which engages with the retainer socket in continuation 27. Accordingly, in the case of parts 18, 19 of the coupling element 17, we are talking about the same structural elements, but which are rotated relative to each other by an angle of 180 ° around the hinge axis S. The inner surfaces of the extensions 24, 25 facing each other; 26, 27 have a radius of curvature adapted to the diameter of the loop pin 11. Their outer contour is fitted to the contour of the guide grooves 12 in such a way that both parts 18, 19, when introducing extensions into the guide grooves, can slide into the receiving hole 6 and can be fixed in each other by means of the extension devices at the ends of the extensions. The central region 10 of the receiving hole 6 has a length that is a maximum permutation stroke less than the distance between the connecting flanges 20, 21, so that the coupling element 17 is arranged to move in the direction of the hinge axis S during the permutation stroke.

As becomes apparent from FIG. 3, the threaded sleeve 13, due to the engagement of its structural parts with each other through the locking connections in its entirety (i.e., in its entirety), undergoes displacement relative to the hinge hinge part in the direction of the hinge axis S when the lower part 14 is rotated. initiating rotational movement of the lower part 14 has an inwardly oriented radial protrusion 28, which, in particular, is visible in figure 5. The protrusion is fitted to the longitudinal groove of the loop pin 11 so that it is biased through the lower portion 14, but is rotationally connected. Therefore, for pivotally actuating the lower part 14 of the threaded sleeve 13, it is only necessary to rotate the loop pin accordingly. As can be seen in FIG. 4, the hinge hinge part 1 has a threaded hole 29 extending across the hinge axis S, which is located approximately in the middle of the longitudinal extension of the hinge part 3 of the hinge hinge part 1 and extends beyond the guide grooves 12 to the central region 10. The threaded hole 29 serves a receiving hole of a countersunk screw 30, by means of which a clamping connection or clamping fit can be made between the hinge hinge part 1 and the loop pin 11. This clamping fit is necessary for eliminate the possibility of turning the threaded bushing 13 with respect to the loop of the casement after vertical adjustment flap, since it would involve a violation of the alignment. In order for the countersunk screw 30 to be an effective stop against force pulling the loop finger in the direction of the hinge axis S, as well as effective protection against burglary, an annular groove 31 is provided on the loop finger 11, the length of which is selected so that the loop finger moves in the casement the loop part is possible at the maximum permutation stroke. The radially protruding bounding surfaces 32, 33 of the loop finger form the stops for the loop finger on the countersunk screw 30.
