Description

Hinge for the articulated fastening of a leaf to a frame about a hinge axis

Technical Field

The invention relates to a hinge for the hinge-type fastening of a wing on a frame about a hinge axis, comprising a hinge part, a hinge pin which defines the hinge axis, an adjustment spindle having a rotational axis and an external thread, and means for guiding the hinge pin sleeve, the hinge part comprising a groove which extends in the direction of the hinge axis and has an inner side, the hinge pin being mounted in a hinge pin sleeve which is arranged in the groove and has an outer side, the adjustment spindle being mounted in a rotationally fixed manner about the rotational axis and in the direction of the rotational axis in a receptacle which is either arranged in the inner side of the groove or in the outer side of the hinge pin sleeve, the receptacle being of circular-segment-shaped cross section and extending parallel to the hinge axis, the adjustment spindle engages with its outer thread with a complementary inner thread which is arranged on the hinge pin sleeve or in the recess and which has a circular segment-shaped cross section, the means being such that the hinge pin sleeve, when displaced in the direction of the hinge axis, executes a pivoting movement about the axis of rotation of the adjustment spindle in a pivoting range.

Background

EP 1982032B 1 discloses such a hinge. In such a hinge, the adjustment spindle simultaneously performs two functions, namely, on the one hand, the guidance of the hinge pin sleeve parallel to the hinge axis and, on the other hand, the displacement of the hinge pin sleeve during a rotational actuation. The latter hinge pin bushing is thereby fixed in the direction of the hinge axis by a threaded engagement with the adjustment spindle in a recess which widens in the adjustment direction, the hinge pin bushing bearing against a wall of the recess which lies opposite the adjustment spindle, but can be moved about the outer circumference of the adjustment spindle in the region of the adjustment spindle by providing a corresponding free angle between the hinge pin bushing and the receptacle. In the embodiment shown in EP 1982032B 1, the guide means provided for guiding the hinge pin sleeve comprise a slide guided in a slide groove, wherein the slide extends obliquely to the hinge axis, as a result of which the hinge pin sleeve and thus the hinge pin supported in the hinge pin sleeve move in an oscillating movement substantially about the axis of rotation of the adjustment spindle.

In practice, it has been found to be disadvantageous in this hinge that the hinge pin bushing often has play in the receptacle which, due to the manufacturing tolerances which always exist, has a negative effect on the quality impression of the hinge.

Disclosure of Invention

The object of the invention is therefore to provide a hinge which is improved with respect to this disadvantage.

This object is achieved by a hinge as specified in claim 1.

In the hinge according to the invention, at least one projection is provided on either the outer side of the hinge pin sleeve or the inner side of the groove on both sides of the adjustment spindle, wherein in the pivoting range at least one of the projections always engages with a recess provided in the inner side of the groove or in the outer side of the hinge pin sleeve. It has surprisingly been found that in practice, despite the static redundancy achieved in the hinge according to the invention, clamping conditions which are to be avoided in practice do not generally occur because the relative movement is impeded or even impeded. In contrast, it is ensured that the hinge pin bushing has no play or only a small play in the receptacle over the entire pivoting range.

The means for guiding preferably comprise at least one guide runner which is inclined to the hinge axis and is arranged either in the inner side of the groove or in the outer side of the hinge pin sleeve. In this case, the term "tilt" should be understood in a broad sense. This means that the guide link runs neither transversely nor parallel to the hinge axis. However, it need not be rectilinear within these boundaries, but may also be curved, i.e. for example curved with respect to the hinge axis.

The at least one guide runner can be arranged in a sliding surface which is formed by the hinge part itself. However, it is also possible and preferred to provide at least one guide runner in the sliding surface of the plain bearing component, which forms part of the inner side of the groove of the hinge part. The latter embodiment includes the following possibilities: the sliding surface is constructed from a material which is particularly suitable for this purpose, for example because of the low coefficient of friction with the material of the hinge pin sleeve.

Preferably, the plain bearing surface extends parallel to the axis of rotation of the adjustment spindle and has a radius of curvature which corresponds to the distance of the plain bearing surface from the axis of rotation. The expressions "parallel to" and "corresponding to … … spacing" and the like are not mathematically exactly understood, but include deviations due to manufacturing tolerances, for example.

If, for example, the at least one guide runner is formed in the inner side of the groove, it is (particularly preferred) if a slide cooperating with the at least one guide runner is provided on the outer side of the hinge pin sleeve.

Particularly preferred is a development of the hinge according to the invention in which exactly two guide runners are provided, which run parallel to one another, and exactly two sliders are provided, which interact with one of the guide runners in each case. It has surprisingly been found that, despite the additional static redundancy which occurs again in this embodiment, the hinge pin sleeve is not easily clamped during pivoting about the axis of rotation of the adjustment spindle within the groove, but rather the hinge pin sleeve is accommodated with particularly little play in the accommodation of the hinge part over the entire pivoting range.

In order to be able to fix the hinge pin in the hinge part against displacement in the direction of the hinge axis, in a particularly preferred embodiment of the hinge according to the invention, a cutout running parallel to the at least one guide runner is provided in the hinge pin sleeve for the passage of a fixing screw, which can be effectively connected to the hinge pin in a force-fitting and/or form-fitting manner by screwing in. In order to keep the hinge pin sleeve displaceable relative to the hinge pin for the purpose of displacement transverse to the hinge axis in the direction of the hinge axis, the cutout has a width in the direction of the hinge axis, which preferably corresponds at least to the sum of the diameter of the fixing screw and the maximum displacement path of the hinge pin sleeve in the direction of the hinge axis.

If, for example, the outer side of the hinge pin sleeve has, preferably, an abutment region for abutment against the sliding surface, which is curved (apart from usual manufacturing tolerances) with a radius which (again apart from manufacturing tolerances) corresponds to the distance of the abutment region from the axis of rotation, this has a positive effect on the mechanical load-bearing capacity of the hinge according to the invention. As a result of this measure, the hinge pin sleeve bears not only on the side of the adjustment spindle against the hinge element via the adjustment spindle, but also, on the side opposite the adjustment spindle, directly or indirectly in a planar manner against the hinge element.

In order to provide the free space required for the pivot pin sleeve to pivot about the axis of rotation of the adjustment spindle, the cross-sectional circular arc portion of the receptacle is 130 ° to 180 °, and the circular arc portion of the internal thread is 150 ° to 160 °. It has been shown that the minimum free angle of 20 ° thus ensured ensures a sufficient pivoting range of the hinge pin bushing about the axis of rotation of the adjustment spindle.

In order to lock the adjustment spindle in the direction of its axis of rotation, it is particularly preferred that the adjustment spindle has an annular groove into which a substantially fork-shaped locking element engages in the state of the adjustment spindle fitted in the hinge part. The locking element can optionally be designed as an insert which can be fixed in the hinge part, whereby the hinge pin sleeve can be fitted and removed together with the adjustment spindle if required.

Detailed Description

The embodiment of the hinge according to the invention shown in the figures comprises a hinge part 100. This hinge part can be not only a leaf hinge part to be fastened to a leaf (for example a door leaf) but also a frame hinge part to be fastened to a frame (for example a door frame). It is part of a hinge for the articulated fastening of a wing, not shown in the figures, to a frame, also not shown, about a hinge axis S. The hinge axis S is defined by the central longitudinal axis of the hinge pin 1.

The hinge piece 100 comprises a recess 2 extending in the direction of the hinge axis S, said recess having an inner side 3. A hinge pin sleeve 4 with a through hole 5 is arranged in the groove 2. The hinge pin sleeve has an inner diameter D which is only slightly larger than the outer diameter D of the hinge pin 1, so that this hinge pin is supported at least substantially without play in the through-opening 5 of the hinge pin sleeve 4 in a direction transverse to the hinge axis S.

The hinge pin bushing 4 has an outer side 6, into which an internal thread 7 with a circular-segment-shaped cross section engages. The circle segment-shaped cross section extends over an angle w of approximately 150 °.

An adjustment spindle 9 with a complementary external thread 8 engages the internal thread 7. The adjusting spindle is mounted in a rotatable manner about a rotational axis X in a receptacle 10 provided on the inner side 3 of the recess 2 of the hinge part 100, which receptacle has a circle segment-shaped cross section extending over an angle W of approximately 180 °. The rotation axis X extends substantially parallel to the hinge axis S. In the direction of the axis of rotation X, the adjustment spindle 9 is fixed in the receptacle 10. For this purpose, the adjusting spindle 9 can have a ring groove 11 into which a substantially fork-shaped locking element 12, which is adapted to the ring groove 11 and is supported on its part in a corresponding seat 13 of the hinge part 100, engages.

At least one end, the adjustment spindle 9 has means for receiving a rotary tool (for example, an internal hex 14). Since the adjusting spindle 9 is mounted in a stationary manner in the receptacle 10 in the direction of the axis of rotation X and the external thread 8 engages in the internal thread 7, a rotational actuation of the adjusting spindle 9 causes a displacement of the hinge pin sleeve 4 parallel to the axis of rotation X.

On the side opposite the adjustment spindle 9, means 15 are provided in the recess 2, which means cause the hinge pin sleeve 4 to execute a pivoting movement about the axis of rotation X of the adjustment spindle 9 in a pivoting range B when it is displaced in a direction parallel to the axis of rotation X and thus in the direction of the hinge axis S. For this purpose, the inner side 3 of the groove 2 widens relative to the outer side 6 of the hinge pin sleeve 4 in the direction of the pivoting movement.

In the embodiment of the invention shown in the figures, these means 15 comprise two

guide runners

16, 17 which run parallel to each other and obliquely to the hinge axis S. The guide link is arranged in a plain bearing component 18 which is placed in the groove 2, the side of which pointing toward the hinge pin sleeve 4 is configured as a sliding surface 19 and forms part of the inner side 3 of the groove 2.

The sliding surface 19 extends parallel to the axis of rotation X of the adjustment spindle 9 and thus parallel to the hinge axis S. The sliding surface is curved with a radius R which corresponds to the distance of the sliding surface 19 from the axis of rotation X.

The plain bearing member 19 is fixed in the direction of the hinge axis S in the recess 2 by means of a stud screw 20 which is screwed into a threaded hole 21 provided for this purpose of the hinge part 100 and which (as will be explained further below) also serves to fix the hinge pin 1 in the direction of the hinge axis S.

For the construction of the means 15, two sliding

blocks

21, 22 are provided on the side of the hinge pin sleeve 4 opposite the internal thread 7, said sliding blocks being adapted to the

guide runners

16, 17. As shown in fig. 1 to 3, the joint pin sleeve 4 rests with a part of its outer side 6 against a sliding surface 19 of the plain bearing component 18. If the hinge pin sleeve is now displaced parallel to the axis of rotation X within the groove 2 by rotationally actuating the adjusting spindle 9, the engagement of the

slides

21, 22 into the

guide runners

16, 17 running obliquely to the axis of rotation X causes a simultaneous pivoting movement of the hinge pin sleeve 4 about the axis of rotation X. In this case, the region of the outer side 6 which bears against the sliding surface 19 slides on this sliding surface. Since (as already mentioned above) the hinge pin 1 is supported substantially without play in the through-opening 5 of the hinge pin bushing 4, the hinge axis S defined by the hinge pin is likewise displaced over an arc of a circle in the pivot range B in this case. Fig. 3 shows the hinge part with the hinge pin sleeve 4 in the right-hand limit position, the maximum displacement path being shown in fig. 3. It will be appreciated that due to this displaceability of the hinge pin 1 and thus of the hinge axis S within the groove 2, the wing can be aligned within the frame in a direction perpendicular to the hinge axis S.

In order to fix the hinge pin 1 in the direction of the hinge axis S, the hinge pin 1 comprises a circumferential groove 23, the width of which is adapted to the diameter of the stud screw 20 in such a way that this stud screw can be screwed with its front end in the screwing-in direction into the circumferential groove 23. In this case, the stud screw 20 passes through the hinge pin sleeve 4 in a cutout 24 whose width b in the direction of the hinge axis corresponds at least to the sum of the diameter of the fixing screw and the maximum displacement path of the hinge pin sleeve 4 in the direction of the hinge axis S.

In order to reduce any play of the hinge pin sleeve 4 in the groove 2 that may occur due to manufacturing tolerances, two

projections

25, 26 are provided on the outer side 6 of the hinge pin sleeve 4 on both sides and symmetrically with respect to the internal thread 7. The two projections extend parallel to the hinge axis S over the entire length of the hinge pin sleeve. Each of the

projections

25, 26 has parallel side faces F and curved edge faces R, which are opposite each other, as shown in fig. 2a, which schematically shows a cross section of the projection. The symmetry line of the edge faces R of the two

projections

25, 26 in the direction of the hinge axis S has an angular separation Ω of approximately 65 ° with respect to the hinge axis S. However, as shown in fig. 2, the

projections

25, 26 are not oriented parallel to the borderlines of this angle, but rather the intermediate faces E between the faces F are inclined towards each other and in the embodiment shown deviate from said borderlines by an angle δ of approximately 20 ° respectively.

The inner side 3 of the groove 2 has two recesses for the

respective projections

25, 26. The projections and the recesses are designed such that, in the intermediate position of the hinge pin sleeve 4 in the groove 2 shown in fig. 2, the two

projections

25, 26 engage with the recesses 27, 28 and at least one of the two projections engages with the associated recess over the entire pivot range B. "engaging" is to be understood in this case to mean that the projection at least linearly contacts the surface bounding the recess.

The embodiment of the hinge part 100 shown in the figures comprises a base body 29 with a hinge part 30 and a fastening part 31. A recess 2 is provided in the hinge 30. The fastener 31 is designed to fit the hinge piece on the visible side of the wing or frame. It should be understood that the invention and the above-described embodiments are not limited to this embodiment. Instead, it is also possible for the fastening means to be provided for mounting on narrow sides of the wing or of the frame, which narrow sides face each other in the closed state of the wing. Furthermore, the illustrated embodiment comprises a cover element 32, which covers the visible side of the base body 29 and of the hinge 30 in the assembled state. A fastening screw 33 is used to fasten the cover element, said fastening screw being screwed through a bore 34 of the fastening element 31 into a thread 35 on the rear side of the cover element.

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