Tape for windows, doors and the like

The invention relates to a hinge for doors, windows and the like for hinge-hinged mounting of a pivotable about a hinge axis wing on a fixed frame, with a frame fastened to the frame hinge part, with an attachable to the wing wing hinge part, with a hinge axis defining hinge pin and arranged with a between the wing hinge part and the frame hinge part, supporting forces from the wing hinge part in the frame hinge part introductory support bearing, which comprises a ball socket and a spherical disk.

Such a band is known from DE 197 45 291 C2. In order to avoid that in a not exactly aligned arrangement of the hinge parts, which can be caused for example by manufacturing or assembly tolerances, jamming of the support bearings is avoided, these each have a free-floating ball socket in a ball socket. This causes the ball disc and the ball socket to move relative to one another transversely to the hinge axis can, whereby the thus formed support bearing also allows a slightly out of alignment arrangement of the band parts.

A disadvantage of this band, however, that its mountability is difficult. Because the free-floating bearing of the spherical disc requires that it is held only by inserting the hinge pin in position. Since usually first the frame and wing hinge parts are separated from each other on the wing or attached to the frame and then the wing is positioned so that the hinge parts of the frame and wing hinge parts at least approximately aligned with each other, and then to introduce the hinge pin, must before insertion the hinge pin at the same time the free-flying spherical disc are used. For this purpose, either another person is necessary, which on the one hand increases the assembly effort and also there is a risk that the person is stuck when inserting the ball disc fingers. Or the spherical disk is positioned, for example, with highly viscous grease. However, there is then the danger that it is displaced out of its position, for example, by counterjumping the hinge part during insertion, so that the assembly process must be repeated.

The invention is therefore the object of developing a generic tape such that the mountability of the wing is facilitated.

This object is achieved by the reproduced in claim 1 band.

Because in the band according to the invention the ball socket and the ball disc of the support bearing are positively engaged with each other, such that a rotation of the same relative to each other about the hinge axis is possible, but not or only by overcoming an elastic in the direction of the hinge axis Force are displaced relative to each other, the ball socket and the ball disc can be fixed pre-mounted on one of the band parts. The danger of a misalignment of the spherical disc to the ball socket in a position which does not allow insertion of the hinge pin, or even a loss of the spherical disc is thereby reliably prevented. In order nevertheless to avoid that in the case of parts of the support bearings which are not exactly aligned, the support bearing and the hinge bolt can be configured in such a way that the hinge bolt passes through the support bearing with radial play. The radial clearance is in this case a maximum of a few tenths of a millimeter, so that an unhindered, jam-free passage of the hinge pin through both hinge parts is still possible if the central longitudinal axes of their hinge parts should deviate a few degrees from an aligned position.

The positive connection of the ball socket and the spherical disk takes place in that the ball socket and the spherical disk abut each other in an angular range which extends to slightly beyond the ball equator. The spherical disk can then be inserted only by deforming it and / or the ball socket, with the region around which the ball socket protrudes beyond the equator and the elasticity of the material made from the ball socket and / or spherical disk being selected in this way in that insertion of the spherical disk can take place with elastic deformation of the edge of the ball socket projecting beyond the equatorial plane. In other words, the spherical disk can be "clipped" into the ball socket prior to assembly of the support bearing on the band part.

The assembly of the frame and wing hinge part for the purpose of mounting a wing in the frame can be facilitated once again when the ball socket of the support bearing is pressed into a bearing receptacle provided in one of the hinge parts. Due to this measure, the support bearings can already be pre-assembled in the factory, which makes handling the belt on a construction site much easier.

In a particularly preferred embodiment of the tape according to the invention, the band part, which comprises the bearing mounts for pressing in the support bearing, the frame hinge part. The wing hinge part can then comprise two hinge parts covering the end faces of the frame hinge part, in other words: it can be a three-part band. Furthermore, it is possible to frame and Flü to swap band member, so that the band part having only a hinge part, the leaf hinge part, the hinge part having two hinge parts is the frame hinge part.

In order to avoid jamming of the hinge pin outside of the support bearing on components of the strip, in the particularly preferred embodiment, the hinge pin and / or the hinge part of the frame hinge part are designed such that the hinge part is penetrated by the hinge pin with radial play.

In a first, particularly preferred embodiment of the band according to the invention, the hinge pin is integrally formed and has distributed over its circumference at least two longitudinal grooves. This embodiment is characterized by a simple manufacturability of the hinge pin. The longitudinal grooves are used to absorb lubricant for permanent lubrication of the belt and for absorbing abrasion, so as to reduce a wear increase on abzulleitender components by abraded particles.

To keep the hinge pin in the longitudinal direction, i. to fix in the hinge parts in the direction of the hinge axis is preferably provided in that hinge part which does not receive the support bearing, preferably a hinge pin bushing.

For fastening the hinge pin bushing in the hinge part of this hinge part, it preferably has an external thread and the hinge part of the hinge part has an internal thread that is complementary to the external thread. The hinge pin bushing can then be fastened by simply screwing it to the hinge part of the band part.

Particularly preferred is a development of the tape according to the invention, when in the hinge pin bushing to the external thread to the outer end of the hinge pin bushing widening cone and on the band part adjoining the internal thread, complementary to the cone formed conical seat are provided. By screwing the hinge pin bush a clamping connection is achieved between the cone and the conical seat, which reliably prevents unwanted, automatic release of the hinge pin bushing. In a further preferred embodiment of the band according to the invention, the hinge pin is formed in two parts. This embodiment is particularly suitable for a three-piece band. For fixing the hinge part only having a hinge part between the two hinge parts of the other hinge part, the two hinge pin parts are then guided in opposite directions from the outside into the hinge parts after positioning the hinge parts to each other, so that their mutually facing ends are located within the middle hinge part.

It is particularly preferred if, for fixing the hinge pin in the axial direction not separate hinge pin bushings are provided, but the two mutually away facing end portions of the two parts of the hinge pin each comprise an external thread and the respective hinge part complementary to the external thread internal thread.

In order to effectively secure the two hinge pin parts against automatic, undesired loosening, the outer thread is adjoined by a cone widening towards the end of the hinge pin and, in the hinge part, a conical seat which adjoins the internal thread and which is complementary to the cone. In this embodiment, in other words, in the case of the previously described existing hinge pin bushings are integrally formed on the two parts of the hinge pin. In the assembly of this embodiment of the tape according to the invention after positioning the tape parts to each other first part of the hinge pin and then mounted the other, wherein already after screwing one of the two hinge pin parts, the band parts are fixed to each other in such a way that the assembly of the other hinge pin part without further support or without further holding the wing is possible.

This embodiment of the tape according to the invention is characterized by a particularly simple assembly.

If - as particularly preferred - the two mutually facing ends of the two parts of the hinge pin are designed such that they are at the complete Turning into the respective associated hinge part transversely to the hinge axis positively engage with each other, the hinge pin at least approximately the same stability against lateral tilting, as an integrally produced hinge pin, but the mountability of the two-piece hinge pin is compared to that gen of the one-piece hinge pin significantly simplified.

In the drawing, two embodiments of the tape according to the invention - are shown schematically. Show it:

Fig.1 a) to e) different views of the first embodiment;

Fig. 2 shows the detail Il in Fig. 1a) in an enlarged detail view;

Fig. 3 a) to c) different views of a support bearing in a single representation and

Fig. 4 a) to d) a second embodiment of a tape according to the invention in different views.

The designated in Fig. 1 as a whole with 100 first embodiment of the tape according to the invention is a so-called three-piece tape. It comprises a wing hinge part 1, which has a flat fastening part 2 which can be fastened to a wing (not shown in the drawing). Formed on the fastening part 2 are two hinge parts 3, 4th

In the recess 5 between the mutually facing end faces 6, 7 of the hinge parts 3, 4 engages a hinge part 8 of a frame hinge part 9, which in turn has an integrally formed on the hinge part 8 fastening part 10. The fastening part 10 is again formed flat and is used for mounting on a frame, not shown in the drawing.

The attachment of the wing and frame hinge parts 1, 9 is a hinge pin 11, which completely passes through the hinge part 8 of the frame hinge part 9 and which with its two end portions 12, 13 protrudes into the hinge parts 3, 4 of the wing hinge part 1.

The hinge pin 11 has distributed over its outer circumference a plurality of longitudinal grooves 14. They serve to absorb lubricant for permanent lubrication of the belt. Furthermore, contaminants, such as attrition, may settle there, so that they can not interfere with the displacement of abutting portions of the belt.

The positioning of the hinge pin 11 in the direction of the hinge axis S defined by it serve two hinge pin bushings 15, 16, one of which is mounted in the hinge part 3 shown in the drawing above, the other in the hinge part 4 shown below.

The hinge pin bushes 15, 16 each comprise a cylindrical part 17 whose outer diameter is adapted to the inner diameter of the hinge parts 3, 4, that it forms a sliding fit with these.

Towards the respective outer end region, the cylindrical part 17 comprises an outer thread 18 and an adjoining cone 19 which widens outward.

The outwardly facing end portions of the hinge parts 3 and 4 are provided with internal threads 20 and conical surfaces 21 which are complementary to the external threads 18 and Koni 19 are designed.

As can be seen in particular in Fig. 1a), the hinge pin 11 rests in the assembled state in central blind holes 22 of the hinge pin bushes 15, 16. The inner diameter of this blind hole 22 is adapted to the outer diameter of the hinge pin such that this at least substantially free of play in the radial direction is recorded.

The hinge pin bushes 15, 16 are so far screwed with their external threads 18 in the internal thread 20 of the hinge parts 3, 4 until the outer surface of the conical 19th O

rests against the respective conical surface 21 of the associated hinge part and forms a clamping fit with this. By this clamping seat an undesirable, automatic release of the hinge pin bushings 15, 16 reliably prevented even under heavy stress of the band.

The hinge pin 11 passes through the hinge part 8 of the frame hinge part 9 in the through hole 23 of an inserted bushing 24. The inner diameter of the through hole 23 is dimensioned so that the hinge pin 11 has slight play in the radial direction of a maximum of a few tenths of a millimeter. Through this game, an insertion of the hinge pin in the hinge parts 3, 4 and 8 of the wing hinge part 1 and the frame hinge part 9 is also possible if the hinge parts are not exactly aligned with each other, as may be the case for example due to manufacturing tolerances.

For the introduction of substantially in the direction of the hinge axis S acting holding forces of the leaf hinge part 1 in the frame hinge part 9 9 support bearings 25 are provided at both ends of the hinge part 8 of the frame hinge part.

As can be seen in particular in FIGS. 2 and 3, each support bearing 25 consists of a ball socket 26 and a spherical washer 27. The ball socket 26 and the spherical disk 27 comprise complementary bearing surfaces 28, 29 which are each formed in the shape of a spherical ring with the same radius that the ball socket 26 and the spherical disk 27 are slidable on each other.

Both the bearing surface 28 of the spherical disk 27, as well as the bearing surface 29 of the ball socket 26 extend slightly beyond an imaginary equatorial plane E addition. As a result of this measure, as can be seen in particular from FIG. 2, the spherical disk can only be inserted into or removed from the ball socket when the ball socket is widened. The use of a sufficiently elastic material for the ball socket 26, for example Teflon, ensures that the spherical washer 27 can be "clipped" without damaging the bearing surfaces 28, 29 before the band is assembled, whereby it is captive. As further Fig. 2 can be removed, both the ball socket 26, and the spherical disk 27 through holes 30, 31 with a diameter which is slightly larger - at most a few millimeters - than the outer diameter of the hinge pin 11. Due to this measure, the Belt pin to compensate for a precisely aligned alignment of the hinge parts 3, 4 and 8 exercise slight tilting, as symbolized by the drawn in Fig. 2 angle α. The ball socket 26 of the support bearing 25 has a cylindrical outer circumference 32 with a stepped diameter and is pressed into a receptacle 33 having a complementary inner diameter in the hinge part 8.

The retaining forces acting in the upper hinge part 3 of the wing hinge part 1 approximately in the direction of the hinge axis S are introduced from the end face 6 of the hinge part 3 via the spherical washer 27 and the ball socket 26 into the hinge part 8 of the frame hinge part 9, since the wing hinge part 1 passes over the end face 6 on the upper end face 34 of a peripheral collar 35 of the spherical disk 27 is supported. The ball socket 26 further comprises pins 36 which are directed toward the interior of the hinge part 8 and which engage in complementary recesses 37 in the hinge part 8 (see FIG. 1 c)), so that the ball socket 26 is non-rotatably mounted in the hinge part 8.

Fig. 4 shows a further embodiment of the tape according to the invention. In order to avoid repetition, only the differences with respect to the band described with reference to FIGS. 1 to 3 will be discussed below, wherein corresponding components increase in their functionality in the embodiment described now with the same reference numerals, but by a value of 100 are.

In contrast to the band 100, in the band 200 shown in FIG. 4, the band bolt 111 is formed in two parts. The two mutually facing end portions 112, 113 of the two parts 111 'and 111 "of the hinge pin 111 each comprise an external thread 118 which engage complementary to the internal thread 20 of the identical hinge parts 3 and 4 as in the embodiment of FIGS End portions 112, 113 of the two parts 111 ', 111 " of the hinge pin 111 also have cylindrical parts 117 and Koni 119, which correspond to the cylindrical parts 17 and the conical 19 of the hinge pin bushes 15, 16 of the embodiment of FIG. 1 to 3.

The part 111 'of the hinge pin 111 shown at the top in FIG. 4 has at its lower end an extension 138 which engages in a complementary recess 139. The hinge pin parts 111, 111 'are secured out of the hinge axis due to these measures against tilting. The hinge pin 111 has a total stability against lateral tilting, which corresponds approximately to that of a one-piece hinge pin.
