SUMMARY OF THE INVENTION

The object of the invention is to provide a hinge according to the introduction in such a way that the adjusting means are not visible from the front face of the adjusting means and are not accessible.

This object is solved by the invention mentioned in the first version in claim 1 and in the second version in claim 13.

This is achieved in that the adjusting means by which the lifting sleeve can rotate are no longer visible between the two parts of the hinge, but are provided at the front end of the lifting sleeve where they are axially accessible from outside and cannot be seen from outside because of the cover sleeve.

The engagement on the lifting sleeve can take place immediately on its front side.

However, an embodiment according to claim 2 is preferred, according to which the engagement takes place at the front end of the hinge pin and is pivotally connected to the lifting sleeve.

Placing the pivot means on the hinge pin is simpler than on the narrow annular front side of the lift sleeve, and operation is also facilitated when mounting the sash.

According to claim 3, the pivotal connection of the hinge pin and the lifting sleeve may be formed by cooperating, deviating circular shapes deviating from the cross-section of the lifting sleeve and the hinge pin, and in accordance with claim 4 in particular on the hinge pin

84252 (84252a)

provided by a protruding polygon over its outer circumference, which engages a corresponding polygonal recess in the region of the end of the lifting sleeve.

In order to fix the hinge pin which is not fixed in the axial direction in this embodiment and in particular to prevent the pivoting connection from being disengaged, the axle position of the hinge pin can be provided according to claim 5.

An alternative pivot connection is the subject of claim 6.

The transverse pin is not only a pivot connection but also an axial lock. In this embodiment, however, it is not possible to disassemble the sash without disassembling the frame and sash.

The invention also applies to the so-called roller hinge, whereby the lifting sleeve is provided in the two-part roller hinge in the frame part of the hinge, and in the case of the three-part roller belt in the lower frame part of the hinge (claim 7).

The roller hinge is characterized in that the hinge parts are substantially cylindrical on the outside with the same diameter and the same axis and the flat hinge wings extend substantially perpendicular to the frame surface, respectively. wings.

The lifting sleeve may have a radial flange at its upper edge, on the upper side of which the wing portion of the hinge rests in order to transmit a proportion of the weight of the wing that it has.

In a first embodiment according to claim 9, the lifting sleeve and the radial flange are one-piece, while in a further form

The embodiment of claim 10 terminates the lifting sleeve at a distance from the upper side of the lower frame portion of the hinge, and a separate sleeve having a radial flange at its upper edge rests on the upper front side of the lifting sleeve.

In both cases, the portion having the radial flange consists of a material which is resistant to pressure and has advantageous frictional properties. This is especially true if the wing portion of the hinge abuts against the radial flange.

However, if the friction-reducing function of claim 11 is transferred to a low-friction material annulus, the low-friction requirements under high load on the radial flange are no longer so high. At the same time, however, the intermediate ring can serve to support the cylindrical sheathing of the lower frame part of the hinge.

In this function, according to claim 12, in the case of a three-part frame hinge, a corresponding intermediate ring can be provided on the upper side of the hinge part of the hinge, which carries the sheathing of the upper frame part of the hinge.

In a second version of the invention, according to claim 13, on the hinge according to the introduction, the lifting sleeve is provided at its peripheral region extending within the hinge part with shapes to engage a rotary tool acting through an opening at the rear of the hinge.

Here, the rotary tool is not engaged, as in the previous version, parallel to the hinge axis, but perpendicular to the hinge axis through an opening at the rear of the hinge. However, this opening is not visible when the wing is closed and is not accessible, so that the adjusting means are also not visible here.

According to claim 14, the shaping of the lifting sleeve can be a peripheral toothing into which, for example, a screwdriver can engage, so that the lifting sleeve can be rotated in steps incrementally with respect to the hinge portion which grips it.

An alternative option to the direct rotation of the lifting sleeve is the subject of claim 15. By means of a Phillips screwdriver, the lifting sleeve can rotate faster than a normal screwdriver, in which only gradual rotation from tooth to tooth can be achieved. However, since the hinge adjustment is performed only occasionally, in fact, only during the first assembly, the speed of rotation does not play a major role.

In a preferred embodiment, the lifting sleeve is provided in the hinge part of the hinge (claim 16), although it would be possible in principle to achieve the same function with the hinge frame part.

Suitably, the lifting sleeve according to claim 17 has at least at its abutment end on which the hinge portion of the second hinge part abuts a sliding ring of a pressure-resistant and low-friction material which can be individually formed according to claim 18.

Thus, the sliding ring has a straight portion acting between the lifting sleeve and an adjacent hinge portion and a cylindrical portion receiving the lifting sleeve.

In order for this part, which engages the hinge part of the part of the hinge engaging the lifting sleeve, to be located there, the shaping according to claim 19 is recommended.

9 9 · · · · ·

Especially in the case of three-part hinges, it is recommended that the same sliding rings be provided at both ends of the lifting sleeve so that the hinges can be fitted without changes to the right and left fittings (claim 20).

The invention can be applied to both a two-piece hinge (claim 21) and i, and this is a preferred embodiment - a three-piece hinge (claim 22).

In the hinge portions 3, 3' are aligned cylindrical through holes, in which the plastic hinge pin bushings 5, 5 'are provided for engagement. the ends of the substantially cylindrical hinge pin 15 extending from the hinge portion 3 through the hinge portion 8 of the hinge portion 20 to the hinge portion 3 '.

Wing portion 20 of the hinge is formed like and has a mounting portion 6 of a plate shape or a block with a flat rear side j, at which the frame portions 10, 10 ¹ of the hinge facing the vertical side is provided in cross-section generally squarish hinge part _8 with rounded corners, which with a slight axial clearance engages between the hinge frame parts 10, 10 'and is penetrated there by the hinge pin 15. The hinge portion 8 has a coaxial threaded hole 9 to the hinge axis S (FIG. 1), into which a lifting sleeve 30 is screwed by its external thread 29, which has a coaxial internal passage 11 to receive the hinge pin 15.

The hinge parts 10, 10 & apos ^; and 20 are made by cutting from an extruded profile of aluminum material and therefore have straight, parallel limiting surfaces at their ends disposed in the direction of the hinge axis, of which 20 ', 20 ''.

The lifting sleeve 30 projects with its lower end 31 over the lower limiting surface 20 '' of the hinge part 20 according to FIG. The lower end 31 is surrounded by a sliding ring 32 z

84252 (84252a)

a low friction-resistant material, such as a suitable plastic or bronze, which is formed at an angle in the cross-section shown in FIG. 1 and passing through the hinge axis S. The cross-section of the sliding ring 32 has a first arm 33 which forms a straight ring that is provided between the lower face 31 ^{1 of the} protruding portion 31 of the lifting sleeve 30 and the upper limiting surface of the lower frame portion 10. the frame portion 10 of the hinge. The sliding ring 32 furthermore has a cross-section extending perpendicular to the arm 33 extending to the cylindrical portion of the sliding ring 32 and surrounding the protruding lower portion 21 of the lifting sleeve 30. a projection 35 into a respective circumferential groove of the projecting portion 31 for axial locking. In order to create space for the arm 34, the threaded hole 9 at reference numeral 36 is removed at a section that corresponds to the maximum previous stroke when the lifting sleeve 30 is rotated into the hinge portion 8 of the wing portion of the hinge.

The hinge wing portion 20 is formed symmetrically to a median plane perpendicular to the hinge axis S, so that also on the upper side of the hinge portion of the hinge protruding sliding ring 32 comes in contact with the hinge frame portion 10 ' 1 lower.

In the region of FIG. 1, the hinge pin 15 has a radially projecting over its cylindrical circumference, in a plane perpendicular to the hinge axis S, an octagonal protrusion 12 which is axially slidable into a correspondingly shaped recess 13 at the upper end of the lift sleeve 30 a pivotal connection between the hinge pin 15 and the lifting sleeve 30.

84252 (84252a) • · · · · · ·

Near the upper end, the hinge pin 15 has a circumferential groove 25 into which a fixing screw 26 is mounted radially in the wall of the hinge pin housing 5 'to lock the hinge pin 15 in the direction of the hinge axis S.

At the upper end, there is a hexagonal recess 14 in the front end of the hinge pin 15, in which it can engage a hexagon key (not shown) to rotate the hinge pin 15. In order to allow access to the hexagonal recess in the direction of the hinge axis S, the bottom of the hinge bush 5, 5 'has a passage 16. The passage 16 and the means for pivoting the lifting bush 30 are stored by covers 17 located on the lower limiting surface of the hinge frame part 10. or. the upper limiting surface of the hinge frame portion 10 '.

Accordingly, it is not possible to recognize the height adjustment means from the front side of the hinge 100, corresponding to the view of FIG. The symmetrical design of the hinge part 20 with both the upward and downwardly extending ends 31 of the lifting sleeve 30 and / or the lower part 20 of the hinged sleeve 30 respectively. with the surrounding sliding rings 32, it also makes it difficult for others to recognize the set stroke changes that are not so much in sight.

The lifting sleeve 30 has approximately an outer circumferential groove 37 in the middle, into which a screw 38 is screwed into the threaded hole of the hinge part 8, by means of which the rotary adjustment of the lifting sleeve 30 is lockable. The threaded hole for the fixation screw 38 is guided from the rear into the hinge portion so that the fixation screw 38 is no longer accessible when the wing is closed.

84251 (84251a)

In all figures, the head bolts of the fastening screws in the fastening portions of the hinge parts are omitted. In FIG. 2 only, the fastening portion 18 is shown in dashed lines and is retained from the rear by fastening means not shown in the bores 19 shown below.

Giant. 4 illustrates that the principle of the invention is also applicable to a two-part hinge. The lifting sleeve 30 'is here not formed symmetrically to the median plane, but ends at a certain distance below the upper limiting surface of the hinge portion 20. The pivotal connection of the pin 15 'of the hinge and bushing 30' in this case is effected transverse pin, which penetrates the upper region of the bushing 30 'the transverse opening and the pin 15 ¹ of the hinge, and which also accepts axial securing axle 15' of the hinge opposite the lifting sleeve 30 '. Here, the hinge pin 15 'also has a hexagonal recess 14 into which the respective screw wrench can be inserted from above. The upper end of the threaded hole 9 of the hinge portion 20 is closable by the cover 22.

Giant. 5 illustrates the application of the principle of the invention to a three-part so-called roller hinge comprising a lower hinge frame part 10, a hinge upper frame part 10 'and a hinge wing portion 20 engaging therebetween. In this case, the hinge pin does not pass through all three parts 10, 20,

10 'hinge, but is divided. The lower hinge pin 15 '' extends in the lower frame portion 10 of the hinge and the wing portion 20 of the hinge. The lifting sleeve 40 is screwed into the thread of the lower frame part 10 of the hinge and has a polygonal recess 14 at the lower end by which the lifting sleeve 40 can be rotated. Use the fixing screw 26 to fix the swivel position. At the upper end, the lifting sleeve 40 has a radial flange 45 on which an intermediate ring 46, which has two

84252 (84252a) • · · · ·

function: on the one hand, it transmits the forces acting downwardly from the hinge part 20 to the lifting sleeve 40 and hence the bottom hinge part 10, and on the other, the intermediate ring 46 serves as a holding for the cylindrical sheath 47 of the lower hinge part 10. The sheath 47 is substantially cylindrical and has an inner annular groove at its upper end into which the intermediate ring 46 engages the peripheral outer bead. Also on the upper side of the hinge part 20 there is provided an intermediate ring 46, which here, however, only functions as a holding for sheathing the upper frame part 10 'of the hinge. Also, the wing portion 20 of the hinge has a casing 48. The sheaths 47, 48, 49 are arranged coaxially one above the other and have the same diameter so that the hinge parts give the impression of rollers.

The hinge parts have a rearward direction; substantially perpendicular to the plane of the frame, respectively. The wings, running flat wings 10 '' and 20 '' of the hinge, which engage between the profiles of the fixed frame and the window frame and are fastened therein by their free ends.

The embodiment of FIG. 10 differs from the embodiment of FIG. 5 only in that the lifting sleeve 40 'has a thread 29 at its lower end, while the lifting sleeve 40 is provided at the top. Besides allowed bushing 40 'radial flange, but this is arranged on a separate housing 28 which bushing 4 0 ¹ extends upwardly at the upper end carries a radial flange 45'. Thus, the upper limit of the lifting sleeve 40 'lies at a distance below the upper limit of the lower frame portion 10 of the hinge.

In the embodiments according to FIGS. 5 and 10, the lifting sleeves 40 and 40 are rotatably carried. 40 ', small radial tabs 27 which are pressed from the material

The hinge pin 15 ' and which engage in the respective notched recesses of the lifting sleeves 40 and 40, respectively. 4 0 '.

FIG. 11 illustrates a hinge 200 that illustrates a second version of the invention. If functionally identical parts are given in the hinges according to FIGS. 1 to 10, the same reference numerals are used.

The hinge 200 is again a three-part so-called articulated hinge. However, a lifting sleeve 50 is screwed into the threaded hole 9 of the hinge part 8 of the hinge part 20, on which a rotational engagement is immediately performed when the hinge 200 needs to be adjusted. The lifting sleeve 50 has a cylindrical coaxial bore 11 through which the hinge pin 15 ''. . Since the hinge pin 15 '' 'does not participate in the rotation transmission, it does not need the corresponding shaping on the hinge pin 15' '', ie. it does not have a hexagonal recess corresponding to the recess 14 of the hinge 100 in its upper or lower face.

To allow the lifting sleeve 50 to rotate, it approximately has a peripheral toothing 41 approximately in the middle of its length, which in the exemplary embodiment occupies approximately a quarter of the total height of the lifting sleeve 50. This span is sufficient to engage the teeth 41 of the peripheral toothing 41 to apply a torque to the lifting sleeve 50. For this purpose, an access 43 is formed from the rear of the hinge wing 20 through the wall of the hinge portion 8 in the form of an aperture 43 (FIG. 14) whose height in the hinge axis S corresponds to the width of the screwdriver blade 42. would be needed to merely extend the blade 42 of the screwdriver. In this way, the tip of the screwdriver blade 42 can be displaced somewhat in the circumferential direction while driving the lifting sleeve 50,

84252 (84252a) Pivot the screwdriver 42 by moving it in the circumferential direction. The spacing of the opening in the circumferential direction must correspond at least to the distance between the outer limitations of the two teeth of the toothing 41 so that the lifting sleeve 50 in the hinge portion 8 can further rotate from tooth to tooth within the meaning of arrow 44 in FIG.

The aperture 43 is located at the rear of the hinge portion 8 so that access to the lifting sleeve 50, as shown in Figs. 13 and 14, is only possible when the sash 24 is pivoted relative to the fixed frame 60, as shown in FIG. 13 and 14. When the sash is closed, it has an opening 43 opposite the fixed frame 60 and FIGS. against the sash 24, which then lies substantially in one plane. Access to opening 43 is no longer possible when the sash is closed. Then, it is no longer possible to see by what means the adjustment of the hinge 200 in the height direction takes place.

FIG. 12 shows a modified lifting sleeve 50 'in which the pivoting engagement is not carried out directly by the hinge pins.

The lifting sleeve 50 'has a trapezoidal groove 51 approximately in the middle of its length. The lower flank 52 of the circumferential groove 51 extends in the direction of the axis with the extending toothed rim 56, which on its inner side leaves a distance from the bottom 54 of the circumferential groove 51. Here too, an opening 43 'is provided on the rear side of the hinge part 20. It has a borehole shape into which a Phillips screwdriver 42 'can be inserted, the cross-bridges 55 engaging between the teeth 53 of the ring gear 56 (FIG. 15). The tip of the Phillips screwdriver 42 'engages in the peripheral groove 51. When the Phillips screwdriver 42' is rotated,

84252 (84252a) The lifting sleeve continues to rotate as in the pinion drive.
