Description

The invention relates to a hinge for a window or a door according to the preamble of claim 1.

Generic hinges of this kind go out of the DE 29605809 U1 and the DE 202006008400 U1 out. In the from the DE 29605809 U1 known hinge, the hinge pin has a cylindrical cross-section with a flattening and passes through two bearing eyes of a frame-side bearing block. The bearing eyes of the bearing block have a matched to the flattening in the cross section of the bearing pin opening so that the bearing pin is rotatably received in the bearing eyes. Between the bearing eyes of the bearing pin passes through a formed from sheet metal substantially cylindrical hinge sleeve, which is provided on the inside with a respect to the hinge sleeve defined plastic sleeve. The plastic sleeve is adapted in cross section to the flattening of the hinge pin. In a pivoting movement of the hinge sleeve and thus the plastic sleeve of the flattened inner diameter of the plastic sleeve is pivoted relative to the bearing pin, wherein the flattened portion of the plastic sleeve enters the cylindrical part of the bearing pin, which leads to a braking movement of the same.

Also in the case of the DE 202006008400 U1 known hinge has the hinge pin a flattening, by which the hinge pin is rotatably received in the bearing block.

A disadvantage of the known prior art is that the production of the bearing pin is relatively expensive. The cylindrical bearing bolts must be provided with the flattening by means of a metal-cutting process, which is a great disadvantage given the high number of pieces required. It can also be provided that a correspondingly shaped wire is provided with the grooves by means of a cutting process. In addition, the introduction the hinge pin in the bearing block in such a shape complicated, in particular due to the limited space in the area of the bands of doors and windows.

From the DE 19514867 C2 a hinge is known in which the bearing pin has a square cross-section. The hinge sleeve has no sleeve, with which a mutual bearing is achieved to the bearing pin.

The object of the invention consists in the remedy of the mentioned disadvantages of the prior art.

To solve a generic hinge is provided that the bearing pin has at least in the region of the hinge sleeve and the bearing block associated lengths a polygonal trained as a uniform cross-section. Thereby, the bearing pin can be made of a polygonal wire by cutting to length and, if necessary, attaching twists and / or compressions. A machining of the shank is not necessary. Due to the cross-sectional shape of the bearing pin can be produced by a rolling process by a wire is rolled with continuous DC cross-section between two plates of constant distance. An equal thickness is a curve of constant width whose closed line always touches all four sides in every position within a suitable square. The longitudinal edges are rounded and the side edges of the cross section - in contrast, for example, to an equilateral triangle - bulbous. In addition, this form compared to a cylindrical cross section, an enormous material savings and thus cost reduction. The same thickness is designed as a three-sided equal thickness.

It is also provided that the sleeve has a matched to the cross section of the bearing pin inner cross-section, so that the rotationally fixed in the hinge sleeve einitzende sleeve causes a rotation inhibition.

This embodiment causes a particularly simple production, in which the bearing pin has a braking position within an opening angle of the hinge of 90 °. In addition, the bearing pin can be inserted in three positions in the bearing block, which facilitates handling.

It is further provided that the bearing pin is provided at the end with a conical portion and the portion has a cross-sectional shape corresponding to the cross-sectional shape of the shaft with a smaller scale on the other hand. The shank is the area of the bearing pin that is associated with the hinge sleeve and the bearing block. As a result, an orientation of the longitudinal side edges relative to the inner cross section of the sleeve is achieved in the assembly of the bearing pin in addition to a centering of the bearing pin itself.

If the bearing pin has a thickened head whose cross-sectional shape corresponds to that of the shank and whose cross-sectional alignment coincides with the cross-sectional orientation of the shank, alignment of the head of the bearing pin protruding beyond the bearing eyes of the bearing block can also achieve alignment of the longitudinal section in the hinge sheath, then that a correspondingly shaped receptacle of an alignment and insertion tool can be relatively aligned with the frame or wing.

Finally, it is provided that the cross-sectional orientation of the bearing pin is symmetrical with respect to a perpendicular to the frame extending normal. This ensures that the bearing pin assumes a defined and easily recognizable alignment position when mounting takes place.

If the bearing pin end has the bearing eyes of the bearing block associated recesses or grooves with a cylindrical cross-section, engage in the locking springs of the bearing eyes for axial positional fixation, this is useful for securing the hinge connection. The grooves can be made by a turning process. Simplified, however, is manufacture by rolling, in which the bearing bolt rolls between two parallel plates, so that, while maintaining the polygonal cross-section in this region, the recesses are produced over the entire circumference with little manufacturing effort can.

The bearing pin 1 of a hinge for a window or a door is shown in the Fig. 1 formed as an elongated pin with a head 3 thickened relative to a shaft 2. The shaft 2 has grooves 4, 5 and an end-side taper 6, wherein the groove 5 is in the region of the taper 6.

In conjunction with the Fig. 2 It can be seen that the groove 4 is widened with respect to the groove 5 and that the spaced apart from the head 3 groove wall has a right angle to the shaft 2, while the groove wall 9 located in the direction of the end 8 occupies a shallower angle. The groove 5 is formed by two extending at shallow angles groove walls 10, 11 almost as a trough. The distance of the groove 5 from the head 3 is denoted by 12, while the taper 6 begins at a distance 13.

Based on Fig. 3, 4 and 5 is in connection with the Fig. 2 recognizable that the bearing pin one of a in the Fig. 3 dash-dotted line circular shape 14 deviating cross-sectional shape 15 has.

The shaft 2 has over its entire length a polygonal polygonal cross-section, in which the longitudinal edges 16 are rounded.

Erfingsgsmäß has - 1 according to the presentation Fig. 3 to 5 Thus, the bearing pin 1 can be produced by a rolling operation by rolling a wire having the cross section of the same thickness between two parallel plates. An equal thickness is a curve of constant width, whose closed line always touches all four sides in every position within a suitable square, so that an equal thickness between the plates rolls like a cylindrical body.

The longitudinal edges of the cross section are rounded and the side edges of the cross section - in contrast to an equilateral triangle - bulbous. In addition, this form over a cylindrical cross-section an enormous material savings and thus cost reduction.

A preferred design of the same thickness provides a ratio of the dimensions 17, 18 of 1.0566. The dimensions 17, 18 describe the diameter of the smaller, accommodated in the same circular arc 18 'and the largest extension of the dagger. The ratio of the radii 19, 20 is preferably 2.5.

In conjunction with the 4 and 5 It is clear that the cross-sectional shape over the entire shaft 2 is the same and also in the groove 5 (FIG. Fig. 5 ) forms an equal thickness. Also, the head 3 may have the cross-sectional shape of a DC dyn whose cross-sectional alignment with the cross-sectional orientation of the shaft 3 coincides. Here, however, a flattened shape is provided with which it is achieved that the head is rotatably fixed in the bearing block 22. This can be achieved by aligning the on the bearing eyes of the bearing block 1 projecting head 3 and an alignment of the seated in the hinge sleeve length portion or shank 2, so that a correspondingly shaped receiving an alignment and insertion tool for the bearing pin 1 on the frame or wing can be relatively aligned, as will be described below.

The proportions of the head 3, the shaft 2 and the grooves 4, 5 are based on the radii 19, 20 are equal, so that the bearing pin 1 according to the aforementioned production with the grooves 4, 5 can be provided by rollers.

In the FIGS. 6, 7 and 8 the bearing block 22 can be seen, which in the exemplary embodiment has two bearing eyes 23, 24, which are connected by a web 25. The bearing block 22 is formed symmetrically to a central axis 26 so that it can be used both for right and left openable wings. In the web 25 openings 27 are provided for receiving fastening screws.

The bearing lugs 23, 24 have bores 28, 29 which are adapted in shape to the cross section of the bearing pin 1, so that it is non-rotatably received in the bearing eyes 23, 24. The bearing lugs 23, 24 are each provided at the end with collar 30, which arise by a reduction in material of the areas located between the sections. The reduction of the wall thickness does not lead to a reduction of the load capacity, since the bearing pin 1 deforms under load and is supported on the end portions of the bearing lugs 23, 24, so that they are loaded more than the lying between them section.

The bores 28, 29 are executed twice discontinued and accordingly have two stages 31, 32. The outer stage 31 is matched to the dimensions and shape of the head 3 of the bearing pin 1, so that it can be rotatably received in the bearing eye 23. For this purpose, the step is provided with a lateral flattening 31 'on which the head 3 rests. The step 32 is on the edge 33 (FIG. Fig. 2 ) of the bearing pin 1 is adjusted such that this edge 33 is at the level of the step 32 of the bearing eye 23 when the head 3 of the bearing pin 1 rests against the step 31 of the bearing eye 24. In addition, the position of the taper 6 is adjusted to the distance between the bearing eyes so that it dips in the above-described mounting position in the bearing eye 23, but not the other hand, enlarged shaft 2. By the taper 6 of the bearing pin 1 relative to the bore 28 or 29th provided with a small game. At a load that leads to a deformation of the bearing pin 1, therefore, the edge 33 of the bearing pin 1 reaches the step 32 and engages behind this, whereby an additional axial fixation of the bearing pin 1 in the bearing block 22 is achieved.

It is in particular from the Fig. 8 recognizable that the cross-sectional orientation of the bearing pin 1 relative to a perpendicular to the bearing block 22 and the frame, not shown, extending normal 34 is symmetrical. This will achieve that the bearing pin 1 assumes a defined and easily recognizable alignment position with respect to the bearing block 22 when the assembly takes place. For mounting the bearing pin 1, an insertion tool can also be provided, which essentially assumes the orientation of the bearing pin 1 relative to a reference edge 34, which preferably coincides with the frame viewing surface. For this purpose, the head 3 of the bearing pin 1 engages, for example, in a corresponding to the shape of the head 3 shaped and sized opening of the insertion tool. By applying a boundary edge of the insertion tool to the reference edge 34, the insertion tool is oriented so that the bearing pin 1 relative to the bore 28, 29 is aligned relative to the bearing block 22 and - due to the mounted on the end 8 of the bearing pin 1 bevel - is insertable , The chamfer on the bearing pin 1 is formed by a conical portion and the conical portion has a cross-sectional shape corresponding to the cross-sectional shape of the shank 2 with a smaller dimension.

The above-described embodiment of the bearing block 1 as a three-sided equal thickness causes in addition to the particularly simple production, that the hinge has a braking position within an opening angle of 90 °. Based on Fig. 9 It can be seen that a sleeve 37 made of elastic material is non-rotatably inserted in the hinge sleeve 36. This is relative to the hinge sleeve 36 by a longitudinal extension 38 rotatably received in the hinge sleeve and has a bore which is tuned in shape and dimension on the bearing pin 1. In a pivoting movement of the hinge sleeve 36, the sleeve 37 is pivoted relative to the rotatably received in the bearing block 22 bearing pin 1, so that the projecting portions of the same dicribes of the bearing pin 1 in a narrower sized section of the sleeve 37 reach. The rotational movement is inhibited under elastic deformation of the sleeve 37. Assuming that the radii 19 are larger than the radii 20 and that the radii 19 are closer to the central axis 39 (FIG. Fig. 3 ) of Gleichdicks are as the radii 20, it follows that with a pivoting movement of 180 °, the smaller sized radii of Gleichdicks of sleeve 37 and bearing pin 1 would mesh again and a maximum braking effect occurs in a 60 ° pivoting movement. This results in a maximum braking torque through the hinge at about 60 °.

Another advantage of the described embodiment is that the bearing pin 1 can be inserted into three positions in the bearing block, which facilitates handling. The design also causes a simplified production of a non-cylindrical and relative to the bearing block rotatably attachable bearing pin.

Finally, it should be added that the ends mounted on the bearing pin 1 and the bearing lugs 23, 24 of the bearing block 22 associated grooves 4.5 - cooperate with not shown here - locking springs for axial positional fixation. The detent springs sit in recesses on the back of the bearing eyes 23,24.
