Description

SUBSTANCE: invention relates to a hinge for hinge with respect to the hinge axis of securing the sash to the frame, comprising a hinge element, which includes a recess extending in the direction of the hinge axis and having an inner lateral surface, defining the hinge axis of the hinge pin, which is installed in a recess located in the recess and having an outer lateral the surface of the hinge pin bushing, having a pivot axis and an external thread, a locating spindle, which is mounted with the possibility of a socket provided either on the inner side surface of the recess or on the outer side surface of the hinge pin bushing, having the shape of a circular segment in cross section and extending parallel to the hinge axis pivot around the pivot axis and is stationary in the direction of the pivot axis and with its external thread is in engagement with a loop provided on the pin bushing or in a recess having the shape of a circular segment in cross-section and a corresponding internal thread, and means for guiding I hinge pin bushings, which cause the hinge pin bush to rotate around the pivot axis of the setting spindle when displaced in the direction of the pivot axis in the pivot area.

A similar loop is known from EP 1 982 032 B1. With this hinge, the setting spindle assumes two functions at the same time, namely, on the one hand, the direction of the hinge pin sleeve parallel to the pivot axis, and on the other hand, when pivotally actuated, displacement of the hinge pin sleeve. The latter, by means of a threaded engagement with the locating spindle, is thus fixed in the direction of the pivot axis inside the recess extended in the direction of adjustment, against the wall opposite to the locating spindle of which it rests, however, it can be moved due to the fact that a corresponding free angle is provided between the bushing of the hinge pin and the seat in the region setting spindle around its outer perimeter. Due to the guiding means provided for guiding the hinge pin bush, which in the exemplary embodiments presented in EP 1 982 032 B1 comprise a rocker guided by a rocker, the rocker being guided at an angle to the hinge pin, the hinge pin bush and thus the hinge pin installed therein move in a pivot motion approximately around the pivot axis of the setting spindle.

In practice, the disadvantage of this hinge has been that the bushing of the hinge pin has, due to the always existing manufacturing tolerances, a free play in the seat, often having a negative effect on the perception of the hinge quality.

On this basis, the object of the invention is to provide a hinge improved in relation to this disadvantage.

This problem is solved using the loop presented in paragraph 1 of the claims.

In the hinge according to the invention, either on the outer lateral surface of the hinge pin bushing or on the inner lateral surface of the recess, at least one projection, respectively, is provided on both sides of the setting spindle, of which, inside the pivot area, at least one always engages with a projection provided on the inner the side surface of the recess or on the outer side surface of the hinge pin sleeve with a recess. Surprisingly, it has been found that in practice, despite the static redundant parts implemented in the hinges according to the invention, as a rule, they do not reach clamping states that should be prevented in practice, since the relative movement makes them difficult or even prevents their occurrence. On the contrary, it has been found that the hinge pin bushing has no or only a slight play in the entire pivot area in the seat.

The guiding means preferably comprise at least one guide link, which runs obliquely to the pivot shaft and is provided either on the inner side surface of the recess or on the outer side surface of the hinge pin bushing. The term "tilted" should be interpreted broadly. This means a guide path travel that does not run across or parallel to the pivot axis. However, within these boundaries, it should not be straight, but can also be curved, that is, for example, curved with respect to the hinge axis.

This at least one guide link can be provided on the sliding surface which is formed by the hinge element itself. However, it is also possible and advantageous to provide at least one guide link on the sliding surface of the sliding bearing element, which forms part of the inner side surface of the recess of the hinge element. The latter embodiment comprises the possibility of forming a sliding surface by means of a material which, for example, due to the lower coefficient of friction with the material of the hinge pin bushing, is better suited for this purpose.

The plain bearing surface extends preferably parallel to the pivot axis of the setting spindle and has a bend radius that corresponds to the distance of the plain bearing surface from the pivot axis. The indications "parallel" and "corresponds to a distance ..." are not to be construed mathematically precisely, but contain deviations due to, for example, manufacturing tolerances.

If, preferably, at least one guide link is formed on the inner side surface of the recess, then most preferably on the outer side surface of the hinge pin bushing there is provided a link stone interacting with the at least one guide link.

Most preferably, an improvement according to the invention of the hinge, in which there are exactly two guiding links running parallel to each other and exactly two link stones interacting with one of the guiding links respectively. Surprisingly, it has been found that, in spite of the secondary additional static redundant parts, in this embodiment, the hinge pin bushing does not tend to jam inside the recess during pivot about the pivot axis of the setting spindle, and the hinge pin bushing is installed in the entire pivot area with as much clearance as possible in the recess of the hinge element.

In order to be able to fix the hinge pin in the hinge element against displacement in the direction of the hinge axis, in the most preferred embodiment of the hinge according to the invention, a hole is provided in the bushing of the hinge pin extending parallel to at least one guide link for the passage of the fixing screw, which by means of screwing can be driven into a kinematic connection with a force and / or form-fit with the hinge pin. In order for the hinge pin bushing to remain displaceable in the direction of the hinge axis in order to be displaced transversely to the hinge axis relative to the hinge pin, the hole has a width in the direction of the hinge axis, which preferably corresponds to at least the sum of the diameter of the fixing screw and the maximum displacement of the hinge pin bushing in the direction hinge axis.

The mechanical strength of the hinge according to the invention is positively affected if, preferably, the outer flank of the hinge pin bushing has an abutment area for contact with the plain bearing surface bent apart from the usual manufacturing tolerances with a radius which, in addition to manufacturing tolerances, corresponds to the distance of the contact area from pivot axis. As a result of this measure, the bush of the hinge pin is caused not only on the side of the setting spindle via the setting spindle to the hinge element, but also on the side opposite to the setting spindle, in a plane directly or indirectly on the hinge element.

In order to create the free spaces necessary for turning the pin bushing around the pivot axis of the setting spindle, the circular segment of the socket cross-section is from 130 ° to 180 °, and the circular segment of the female thread is from 150 ° to 160 °. It has been found that the minimum free angle of 20 ° provided in this way provides a sufficient pivot area of the hinge pin sleeve about the pivot axis of the setting spindle.

For locking the locating spindle in the direction of its pivot axis, it may most preferably have an annular groove with which, in the mounted state of the hinge element, the locating spindle engages an approximately fork-shaped locking element. The latter can be made in the form of an insert element which can be fixed at will in the hinge element, as a result of which, if necessary, the hinge pin bushing can be mounted and dismounted together with the setting spindle.

The drawing shows schematically an exemplary embodiment of the invention. It shows:

fig. 5 - the same loop element in the corresponding FIG. 4, but in a rear perspective view.

The illustrated embodiment of the hinge according to the invention includes a hinge element 100. When referring to this hinge element, we can talk about both being fixed on the leaf, for example, on the door leaf, a leaf hinge element, and on the frame, for example, on the door frame, a frame hinge element. It is a component of a hinge for the sash, which is not shown in the drawing, on a frame which is also not shown, which is hinged about the hinge axis S. The hinge axis S is defined by the longitudinal middle axis of the hinge pin 1.

The hinge element 100 includes a recess 2 extending in the direction of the hinge axis S, which has an inner lateral surface 3. Inside the recess 2 is located a bushing 4 of the hinge pin with a through hole 5. The latter has an inner diameter d, which is only slightly larger than the outer diameter D hinge pin 1, so that it is installed at least substantially without play in the through hole 5 of the hinge pin sleeve 4 in a direction extending transversely to the hinge axis S.

The hinge pin bushing 4 has an outer lateral surface 6 on which a circular segment-shaped internal thread 7 is made. The circular segment-shaped cross-section extends along an angle w of approximately 150 °.

In engagement with the internal thread 7 there is a mounting spindle 9 with a mating external thread 8. It is installed with the possibility of rotation about the axis of rotation X in the slot 10 provided on the inner side surface 3 of the recess 2 of the loop element 100, which has a circular segment extending along the angle W at approximately 180 ° cross section. The pivot axis X runs approximately parallel to the pivot axis S. In the direction of the pivot axis X, the setting spindle 9 is fixed in the seat 10. For this, the setting spindle 9 can have an annular groove 11, with which an approximately fork-shaped locking element adapted to the annular slot 11 engages 12, which is mounted on its side in the corresponding socket 13 of the hinge element 100.

At least at one end end, the setting spindle 9 has a measure for attaching a rotating tool, for example, an internal hexagon 14. Due to the installation of the setting spindle 9 in the seat 10, which is fixed in the direction of the X axis of rotation, and the engagement of the external thread 8 on the internal thread 7, the action of the setting spindle 9 causes the hinge pin bushing 4 to move parallel to the pivot axis X.

On the side opposite to the locating spindle 9, means 15 are provided inside the recess 2 which cause the hinge pin bush 4 to pivot parallel to the X-axis and thus in the direction of the pivot axis S in the pivot region B in the pivot area B about the pivot axis X of the locating spindle 9. For this, the inner side surface 3 of the recess 2 is widened relative to the outer side surface 6 of the hinge pin sleeve 4 in the direction of the pivot movement.

In the illustrated embodiment of the invention, these means 15 include two guide links 16, 17 which run parallel to each other and obliquely to the pivot axis S. They are provided on a sliding bearing element 18, which is exposed in the recess 2, and facing to the bushing 4 of the hinge pin, the side of which is made in the form of a sliding surface 19 and forms part of the inner side surface 3 of the recess 2.

The sliding surface 19 extends parallel to the pivot axis X of the setting spindle 9 and thus parallel to the pivot axis S. It has a bend with a radius R that corresponds to the distance of the sliding surface 19 from the pivot axis X.

The fixing of the sliding bearing element 19 in the recess 2 in the direction of the hinge axis S is carried out by a threaded rod 20, which is screwed into the threaded hole 21 of the hinge element 100 provided for it, and which, as will be described below, also serves to fix the hinge pin 1 in the direction of the hinge S axis.

For the implementation of the means 15, two hinge pins 21, 22 adapted to the guide links 16, 17 are provided on the side of the sleeve 4 opposite the internal thread 7 of the bushing 4. As can be seen in FIG. 1 to 3, the bush 4 of the hinge pin bears part of its outer side surface 6 to the sliding surface 19 of the sliding bearing element 18. If the hinge pin bushing is now displaced by pivotally actuating the setting spindle 9 parallel to the pivot axis X inside the recess 2, the engagement of the rocker stones 21, 22 over the guide wings 16, 17 running at an angle to the pivot axis X causes a simultaneous pivotal movement of the pin bushing 4 loops around the X axis of rotation. In this case, the area of the outer side surface 6, which is adjacent to the sliding surface 19, slides along it. Since, as already mentioned above, the hinge pin 1 is installed substantially without play in the through hole 5 of the hinge pin bushing 4, the hinge axis S defined by it is also displaced along a circular arc inside the pivot region B. The maximum displacement path is indicated in FIG. 3, in which the hinge element with the bushing 4 of the hinge pin is shown in the right extreme position. It should be understood that due to this possibility of displacement of the hinge pin 1 and thus of the hinge axis S within the recess 2, the sash can be adjusted within the frame in a direction perpendicular to the hinge axis S.

For fixing the hinge pin 1 in the direction of the pivot axis S, the hinge pin 1 includes an annular groove 23, the width of which is adapted to the diameter of the threaded rod 20 so that it can be screwed into the annular groove 23 with its front end in the screwing direction. The threaded rod 20 passes through the bushing 4 of the hinge pin in the hole 24, the width b in the direction of the pivot axis of which corresponds at least to the sum of the diameter of the fixing screw and the maximum displacement path of the bushing 4 of the hinge pin in the direction of the pivot axis S.

To reduce the possible free play of the bush, which is possible due to the manufacturing tolerances of the bushing 4, the hinge pins inside the recess 2 are provided on the outer side surface 6 of the bushing 4 hinge pins on both sides and two protrusions 25, 26 symmetrically relative to the internal thread 7. They extend parallel to the pivot axis S along the entire length of the bushing of the hinge pin. Each of the protrusions 25, 26 has opposite, parallel side surfaces f and a curved edge surface r, as can be seen in FIG. 2a, which schematically shows a cross section of the projection. The lines of symmetry of the edge surfaces r in the direction of the hinge axis S of both protrusions 25, 26 have an angular distance относительно relative to the hinge axis S of about 65 °. As shown in FIG. 2, the projections 25, 26 are oriented, however, not parallel to the limiting lines of this angle, but the middle planes E between the surfaces f are inclined towards each other and deviate in the illustrated embodiment from the limiting lines by an angle δ of approximately 20 °, respectively.

The inner side surface 3 of the recess 2 has two recesses for one of the projections 25, 26, respectively. The projections and recesses are made in such a way that in the depicted in FIG. 2 in the middle position of the bush 4 of the hinge pin in the recess 2, both protrusions 25, 26 are in engagement with the recesses 27, 28, and throughout the pivot region B, at least one of both projections is in engagement with the corresponding recess. By "engaging" it is to be understood in this connection that the protrusion is at least linearly in contact with the surface that defines the recess.

The illustrated embodiment of the hinge element 100 includes a main body 29 which has a hinge portion 30 and a fastening portion 31. A recess 2 is provided in the hinge portion 30. The fastening portion 31 is designed to mount the hinge element on the visible side of the sash or frame. It should be understood that the invention and the above-described embodiments are not limited to this concept. On the contrary, it is also possible to provide a fastening part for fastening to narrow sides of the sash or frame, which face each other in the closed state of the sash. The further illustrated embodiment includes a cover cap 32, which in the assembled state covers the visible sides of the main body 29 and the hinge part 30. It is secured by a fastening screw 33, which can be screwed through the hole 34 of the fastening part 31 into a thread 35 on the reverse side of the cover cover.

It should be noted that the invention and the above-described embodiments can also be implemented without a cover cap.
