Abstract

The hinge has sections (12,14) for joining to the fixed frame (11) and to a leaf (13). It also has a hinge pin (15) whose ends engage in bushes (16,17). One bush has external positioning lugs engaging with recesses (20,20',20") contained in a recess (21) at right angles to the pin and formed in one of the hinge sections. The lugs on the bush are distributed over the bush periphery at intervals in more than two directions. The recess in the hinge-section has one or more smooth wall-sections (22), in which recesses are formed accommodating some of the lugs. The lugs can be of different lengths, typically altering by a few millimetres at a time. One or more lugs can be radiused at the end to match the bush curvature, being adjacent to a correspondingly radiused support on the bush.

Description

The invention relates to a door or window hinge, with one that can be attached to a fixed frame Frame hinge part, with a sash hinge part that can be attached to a sash, and with an axle pin, the ends of which are in bearing sleeves engage, at least one of which is on its outer circumference Has positioning tabs that have positioning tabs work together in a cross to the axis pin elongated positioning recess of a band part are arranged.

With a door hinge known from EP-B-0 223 186 with The above features are the positioning tabs and the positioning recesses formed by gears, which are on flat, opposite surfaces of the Band parts are. Their elongated positioning recesses are essentially rectangular as a result. For space reasons the teeth will have to be kept flat. Accordingly, the safety of intervention is low and the - Tolerances easily exceed the permissible level because the the gear manufacturing tools wear out. It is therefore, more frequent tool changes are required, reducing manufacturing costs of the known hinge drives up.

The invention is therefore based on the object, a door or Window hinge with the characteristics mentioned above improve that the security of engagement of the bearing sleeves in the tape parts improved and the manufacturing cost of the tape be lowered.

This object is achieved in that the bearing sleeve in is essentially circular or square and the positioning tabs beyond the scope in more than two directions are distributed, and that the positioning recess of the band part at least one of the Circumference or the square circumference of the bearing sleeve adapted has smooth wall section in which the positioning recesses for at least part of the positioning protrusions are arranged.

It is essential for the invention that the bearing sleeve is circular or square. The above positioning projections distributed around the circumference can then comparatively with regard to the known gearing large engagement lengths are formed what tamper resistance improves. In addition, the tolerance fields the positioning tabs and the positioning tabs be kept larger so that a Tool wear can not affect that the additional tolerances not only after a short time Tool use may be exceeded. With this training The tape has the advantage that the angular Adjustment of a bearing sleeve for adjustment in just one single positioning direction leads. It gets eccentric trained bearing sleeves avoided given disadvantage, that any angular adjustment of such a bearing sleeve for simultaneous changes in position in two directions leads, so that no mutually independent adjustments can be done in two directions namely parallel to the wing and in the direction of the wing pressure.

To by adjusting a bearing sleeve in several angular positions different positions within the to achieve elongated positioning recess of a band part, the band is expediently designed so that the positioning tabs of different positions the bearing sleeve in the elongated positioning recess are accordingly of different lengths. The different Long protrusions help keep the bearing sleeve can only take defined positions that are differ in their arrangement. Exploited is that a longer lead will not line up there lets where a shorter projection is provided.

The tape can be designed so that the length of the Positioning projections are graduated by the millimeter. A Millimeter gradation is sufficient, for example the pressure conditions of the sash on the frame or the positioning to adjust the sash parallel to the frame.

If at least one positioning projection on the hinge side is rounded off according to the circumference of the bearing sleeve, can this projection within the circumference of the bearing sleeve be arranged, so that it is on this circumference is present. It then serves to support the bearing sleeve on the belt, which increases the resilience of the belt, for example against tilting moments.

An improvement in the support of the bearing sleeve on the band can also be achieved in that a positioning projection a rounded according to the circumference of the bearing sleeve Outrigger is adjacent. With the support can can be achieved, as well as with a rounded positioning projection, that larger areas for the forces to be removed of the bearing sleeve are available so that the positioning projections, which is generally due to the load transfer from the Bearing sleeve involved on the band part, relieved accordingly e.g. with tipping loads from the wing, such as they occur, for example, when the door is opened.

But it is particularly advantageous to design the tape that the bearing sleeve on its circumference in a positioning recess engaging stabilization lead having. This lead in stabilization can also be achieved serve to position the bearing sleeve if the positioning projections are arranged so that they are in all not all of the intended rotational positions of the bearing sleeve interact positively with it, not all of it contribute to securing their position in the volume. In this case the stabilization tab takes on the role of a positioning tab.

It is quite possible the positioning tabs and setbacks so that they are only one Extend part of the sleeve length. Such jumps or jumps having components could, for example, by Injection molding. In a special way it will Band designed so that the positioning projections and / or the stabilizing projection and / or the supports about sleeve-length ribs and the positioning recesses are about sleeve-length grooves.

A stabilization of the position of the bearing sleeve within the positioning recess of a band part can be by three positioning protrusions with 90th Angular degrees are distributed over the circumference of the bearing sleeve, and that the two outer projections offset parallel to each other are. Leave with the three positioning tabs three different positions of the bearing sleeve within the elongated positioning recess of a band part to reach. The resulting triple gradation enables enough different positions for the Bearing sleeve and at the same time also sufficient solidity or sufficient design lengths in the area of the projections or recesses. In this case, the entire length of the involved Components used in each case to the when using the Tape occurring forces, which in the sense of a low Bearing wear and also makes production easier, because the components in question are extruded can.

In adaptation to a design of a bearing sleeve The tape can be formed three positioning projections be that the positioning recess three with 90 angular degrees positioning recesses distributed over their circumference Has. The distribution of the returns is done in coordination on the distribution of the protrusions.

Especially with regard to the aforementioned vote the band is formed so that the two outer recesses corresponding to a parallel displacement of two outer ones Positioning projections offset parallel to each other are.

The band is expediently designed such that at least the two outer positioning recesses of the Length of the longest corresponding to the positioning protrusions are deep. In the two corresponding to these returns Positions of the bearing sleeve can be the longest positioning projection intervene in each of these recesses what the assembly safety of the bearing sleeve with the band part enlarged so that the long length of the longest positioning projection for two of the three possible positions the bearing sleeve in the band part in the sense of improved stabilization can be exploited.

The aforementioned advantage applies in particular if the positioning recess in the band part is double mirror image is trained. The double mirror image Formation of the positioning recess in the band part has especially the advantage that the number of possible Positions of the bearing sleeve in the band part is doubled. Instead of for example three possible positions of the bearing sleeve in the band section there are a total of six different positions enables so that starting from a central zero position three further positions of the bearing sleeve in each direction within the elongated positioning recess of a band part can be reached.

Are the positioning recesses of both parts of the belt each formed double mirror image, so the wing starting from a central zero position, for example perpendicular to the wing plane in six different Pressure positions can be adjusted, as well as horizontally wing parallel adjustment in six different Positions is possible. In none of the above cases will by setting the bearing sleeve within the elongated Positioning recess a vertical wing parallel adjustment of the wing hindered if, for example, in one of the wing band parts is provided.

1 in a partially sectioned side view Door hinge 10 shown consists essentially of a Frame hinge part 12 and a wing hinge part 14. The frame hinge part 12 is struck on the fixed frame 11, which was shown schematically in Fig.2. A stabilizing pin 25 engages in this frame 12 and the attachment takes place using fastening screws, not shown, through mounting holes 26 of the frame hinge part 12 screwed through into the fixed frame 11 will. The wing hinge part 14 is with a mounting plate 27 provided with a stabilizing bolt 28 is assembled, which is shown schematically in a Wing 13 engages. On the wing, not shown 13 is fastened by means of fastening screws, not shown through mounting holes 29. The Mounting holes 29 are covered by a cover plate 30, which is fixed with the help of an adjusting screw 31 becomes.

The two belt parts 12, 14 are assembled by means of an axle pin 15 and two bearing sleeves 16, 17, the each in a positioning recess 21 of a band part 12, 14 are used. The bearing sleeves 16, 17 are specific designed as sockets, so they are at their from each other groundbreaking ends essentially closed and on their mutually facing ends flange-like ring collar, with which they are supported on a circumferential ring of the axle pin 15, each on one side of this ring 15 '. On the other hand each ring collar of a bearing sleeve 16, 17 lies on one Front side of a band part 12, 14. The bearing sleeves 16, 17 are made of slippery material, so that there is a low friction Material pairing in the relatively moving area of the hinge 10 between the band parts 12, 14, the bearing sleeves 16, 17 and the axle pin 15 or its axle ring 15 'results. For setting the contact forces in this area are above Bearing sleeve 17, a plug 32 is arranged in the recess 21.

The bearing sleeves used in the band parts 12, 14 16, 17 are each identical. Every bearing sleeve 16 or 17 has an inner diameter that corresponds to the Outside diameter of the pin 15 is matched. The outer circumference the bearing sleeves 16, 17 is essentially circular, as can be seen above all from Fig. 4. Over the outer circumference 18 of the bearing sleeve 16 are positioning projections 19 distributed up to 19 ''. These are positioning tabs offset at right angles or parallel to the axis. The positioning projection 19 is the only one aligned with the center 33 or the longitudinal axis of the bearing sleeve 16. Er is the longest and is about 90 degrees to the two other positioning projections 19 ', 19' 'offset, so that the latter arranged on both sides of the positioning projection 19 are. The positioning projection 19 'is aligned not with the center of the bearing sleeve 33, but is about its half width parallel to itself towards Projection 19 arranged offset. Arranged accordingly is the projection 19 '', but practically one Width. All three projections 19 to 19 '' are the same width.

The projection 19 is not rounded, while the two Projections 19 ', 19' 'are rounded at their ends. It is a rounding with a radius R that corresponds to the radius R of the The outer circumference of the bearing sleeve 16 is the same. The radius centers 34 of the projection 19 'and 35 of the projection 19' ' in alignment with the center 33 of the sleeve 16. This Escape is arranged transversely to the projection 19. The center of the radius 34 is offset by 1 mm from the center 33, while the radius center 35 to the center 33 to on the other side is offset by 2 mm. The lower transfer of the radius center 34 results in combination with the shorter length of the projection 19 'the possibility of the projection 19 'at a suitable angular position of the sleeve 16 a circular section 22 of the elongated positioning recess 21 of a band part 12, 14 to rest. Corresponding applies to the 2 mm and thus larger displacement of the radius center 35 of the rounding of the projection 19 '' for a different angular position of the bearing sleeves 16, 17.

Furthermore, the bearing sleeve 16, 17 with a stabilizing projection 24 provided the positioning projection 19 is opposite, but by a width of the projection 19 is offset parallel to this, namely to Side of the longer of the projections 19 ', 19' '. The interaction of the stabilizing protrusion 24 with the positioning protrusions 19 to 19 '' will refer to the illustration 5a to 5g explained.

Between the positioning projection 19 and the ones adjacent to it, positioning projections offset by 90 degrees 19 ', 19' 'supports 23 are arranged. These supports are projections, the outer circumference 23 'of which Radius R, the radii centers being identical with which the projections are 19 ', 19' '. Consequently the outer peripheral surfaces 23 'of the supports 23 together with the outer peripheral surfaces of the rounded ends Projections 19 ', 19' 'support areas lying on a single radius, of which are in different angular positions the bearing sleeves 16, 17 one at a time Support the circular section 22 of the positioning recess 21 can.

The elongated positioning recesses 21 of the band parts 12, 14 are each the same, with their However, the longitudinal axis is arranged differently. While the Recess 21 of the band part 12 arranged vertically to the window plane the recess 21 of the wing hinge part extends 14 with its longitudinal axis parallel to the wing plane. When the wing is closed, the recesses 21 are 90 degrees arranged rotated to each other.

Each recess 21 consists of two circular sections 22, the center of their radii on a straight line through the longitudinal axis 15 '' of the band or the axle pin 15. Everyone Radius center of a circular section 22 is by 3 mm from this axis 15 '' away. In addition, each recess is 21st or each circular section 22 with positioning recesses 20 to 20 '', so that a recess 21 in total has six positioning returns 20 to 20 ''. These returns 20 to 20 '' are given in Fig.3. The returns 20 ', 20' 'are so long that the projection 19 fits into them. Of the Return 20 is so long that the stabilization projection 24 fits, but not another lead. Furthermore are the positioning recesses 20 ', 20' 'with respect to FIG the axis 15 '' offset as well as the projections 19 ', 19' ' with respect to the center 33. This also applies to the positioning recesses 20 to 20 '' of the further circular section 22 with the proviso that they are arranged double mirror image are. The positioning recesses 20 are therefore on both sides the longer transverse axis of the recess 21. The positioning recesses 22 'lie on both sides of the shorter transverse axis the recess 21, as well as the positioning recesses 20 '', but with a corresponding offset from this Axis away in the direction of the respective recesses 20. Is between the projection 19 'or 19' 'and the support 23 each have a recess 23 '' for engaging the recess 20 or 20 '' intermediate web ends.

As a result of the training described above, each bearing sleeve 16, 17 in the associated band part 12, 14 in seven Positions are arranged, which are shown in Fig.5a to 5g are. The middle position is shown in Fig. 5d, from which also the respective longitudinal axes Z, X of the frame hinge part 12 and the wing hinge part 14 can be removed. The relative rotation adjustment of the bearing sleeve 17 or the bearing sleeve 16 is symbolized by the double arrow 36. In this case, that's from the relative position of the frame band 12 to the wing hinge 14, the mids are aligned the elongated positioning recesses 21 of these two Band parts 12, 14.

The bearing sleeve 17 turns counterclockwise by 90 degrees arranged twisted and assembled with the wing hinge part 14, the positioning projection 19 and the stabilization projection engage 24 each in a recess 20 'or 20 '', so that a relative adjustment of the bearing sleeve 17 in the elongated recess 21 is not possible. The position the bearing sleeve 17 is by the abutment of the rounded end of the projection 19 '' with the associated support 23 on Circle section 22 stabilized.

Another arrangement of the bearing sleeve rotated by 90 degrees 17, starting from the position shown in Fig.5c is not possible because the projection 19 for the recess 20 is too long. As a result, the bearing sleeve 17 becomes more Adjusted 90 degrees so that they engage in a 20 "recess can, cf. Fig. 5b. In this position, the Projection 19 'with its rounding and the one assigned to it Stabilizers 23 from the circular section 22, whereby the bearing sleeve, however, by plus 2 mm in relation to the position 5d is offset. A further offset of 3 mm results 5a, that is to plus 3 mm, the two Engage projections 19 ', 19' 'in the recesses 20', 20 '' and the stabilization protrusion 24 in the recess 20.

Since the recess 21 has a double mirror image is, with corresponding rotational positions of Bearing sleeve 17 from the position of Fig.5d clockwise corresponding arrangements within the other Circular section 22 of the recess 21 by minus 1 mm, see Fig. 5g, by minus 2 mm, see Fig. 5f and by minus 3 mm, see Fig.5g. Such a seven-step adjustability is in usually sufficient to master the assembly tolerances.

With the extreme adjustments of the bearing sleeve 16, 17 in Regarding the normal position of FIG. 5d, three projections engage 19 ', 19' 'and 24 in three recesses 20 to 20' '. It there is good positional security. In the other two Positions deviating from the zero position according to FIG. 5d the long positioning projection 19 engages in combination with the stabilizing projection 24 in recesses 20 ', 20' ' and a free return is supported with its rounding and the adjacent support 23 on the Circle section 22, so that even with these arrangements Bearing sleeves 16, 17 ensure good stabilization.

6, those parts which correspond to those of FIG. 3 are provided with the same reference symbols. A bearing sleeve 16 which is essentially square in cross section or in the area of its outer circumference is present. This bearing sleeve 16 also has positioning projections 19 to 19 ″ , as has the bearing sleeve shown in FIG. With respect to the center 33 or with respect to the longitudinal axis 15 ″ of the axle pin 15, these projections 19 to 19 ″ are arranged in the same way. This applies to the inclusion of the stabilization projection 24. The only difference is that the projections 19 to 19 ″ and 24 project from flat outer surfaces and are not rounded at their ends, since they are not used for additional support tasks.

The positioning recesses 20 to 20 ″ of the embodiment of the band part 12 of FIG. 6 are also arranged for the positioning recesses 20 to 20 ″ according to FIG. The positioning recess 21 of the band part 12 is rectangular in view of the square design of the bearing sleeve 16. All four surfaces of the rectangular recess are flat. Accordingly, there is a backlash-free assembly of the square bearing sleeve with the band part 12 in each of the seven possible positions of this bearing sleeve 17 within the positioning recess 21.

It is understood that the bearing sleeve 17 accordingly could be square. However, it is also possible, the bearing sleeve 17, that is to be assigned to the band part 14 Bearing sleeve to form with an annular cross section or the other way around. Such a bearing sleeve with an annular Cross section could also be rectangular Positioning recess 21 are used according to Figure 6, then with stability disadvantages.
