Description

The invention relates to a fitting for pivotally fastening a wing to an associated frame, in particular for hanging the wing of a window or a door on the frame of the window or the door, with a first fitting part, which is provided with a pin, the axis of which forms the pivot axis of the fitting, and a second fitting part, which has a recess provided for receiving the pin, and with first fastening means for fastening one of the two fitting parts on the frame and second fastening means for fastening the other fitting part to the sash and also with adjusting means for adjusting the sash relative to the frame, which comprise adjusting means for adjusting the sash parallel and perpendicular to the frame.

A fitting of this type is known and has been used for some time mainly for hanging window sashes on the associated window frames. This known fitting fulfills a requirement which has arisen in recent years in connection with the efforts to avoid heat loss from windows and which is aimed at solo heat loss through window sashes fitting as precisely as possible into the window frames or as narrow as possible gaps between window frames and to keep window sashes as small as possible when the window is closed and, for this purpose, to prevent the window sash that fits exactly into the frame from being rubbed or placed on the window frame when the window is closed, so that the position of the window sash relative to the frame can be adjusted so that when the window is closed remaining narrow gaps between window sash and window frame are approximately the same size everywhere. For this purpose, the aforementioned adjustment means for adjusting the sash relative to the frame are provided in the above-mentioned known fitting of the type mentioned. Of course, with the previously usual fittings, the were not provided with such adjustment means, grinding or placing the window sash on the window frame when the window was closed, but for this purpose relatively wide gaps between the sash and frame with the window closed were provided in the previously usual windows, which were used in the assembly of the Fittings on sash and frame allow for mounting tolerances without the risk of such sole lifting or touchdown, and these relatively wide gaps between sash and frame then lead to a relatively large air flow through this gap when the window is closed and thus to the heat losses mentioned.

In the above-mentioned known fitting of the type mentioned, the adjusting means for adjusting the wing relative to the frame are now constructed such that the first sole part to be fastened to the frame, provided with the pin, is both solder-free to the frame or to its first fixed to the frame Fastening means is adjustable as well as parallel to the frame, while the second base part to be fastened to the wing, provided with the recess provided for receiving the pin, is firmly and immovably connected to the wing or to its second fastening means fixedly attached to the wing. It is therefore apparently assumed with this construction that the adjustment of the movable wing relative to the fixed one Frame must take place on the fixed part and thus on the frame or on the fitting part attached to the frame.

This construction of the known fitting of the type mentioned has a whole series of disadvantages due to the fact that the fitting part to be attached to the frame is adjustable both perpendicularly and parallel to the frame, because the adjustability in two directions requires in connection with the Necessity that the adjusting means for this adjustment must still be easily accessible in two directions when the fitting part is fully mounted on the frame, a setting mechanism that is relatively complex both in terms of technology and space, and to be accommodated in the frame with the known fitting Pot is required. The primary disadvantages of the known fitting are therefore a relatively high technical outlay and the necessity that the frame for fastening the known fitting must be provided with a large pot-shaped hole and the cost of the work involved is often of the same order of magnitude as the manufacturing cost of the entire fitting. Even more serious than these primary disadvantages is a secondary disadvantage, which is related to the construction of the previously mentioned fittings which are customary above and which are not provided with adjusting means for adjusting the sash relative to the frame Without fittings, a setscrew is provided on each of the two base parts belonging to a fitting as fastening means for fastening to the wing or on the frame, which is firmly connected to the fitting part in question. The base parts and the set screws of these fittings can now be screwed mechanically into sashes and frames using so-called screw-in machines, which have been known for a long time and are widely used in the relevant industry, so that due to the widespread use of these screw-in machines for mounting these In the past, fittings on the sash and the frame, which were provided with set screws as fastening means, resulted in relatively low assembly costs. In the above-mentioned known fitting of the type mentioned, however, only the second fitting part to be fastened to the sash, which, like the previously usual fittings, is firmly and immovably connected to its fastening means for fastening to the sash, is provided with such a threaded pin as fastening means, while the first fitting part to be fastened to the frame, as mentioned above, has a pot to be sunk into the frame, so that only the second sole part can be masohinellly and thus inexpensively assembled from this fitting with the screwing machines usually already available from the manufacturers, while the first part is being assembled Fitting part of this fitting either a considerable amount of manual work or, for fully automatic assembly, a separate assembly machine to be developed for this purpose and thus in each Fall. A much higher cost than is required to assemble the previously usual fittings either because of the labor-intensive manual work or because of the acquisition costs for the separate assembly machine.

The problem underlying the invention was therefore to create a fitting of the type mentioned with a simple constructive basic concept, in which the technical and spatial expenditure for the adjusting means is significantly less than in the known fitting of the type mentioned and which also makes it possible to design the fitting in such a way that it can be mechanically mounted on the sash as well as on the frame using the existing screwing machines.

According to the invention this is achieved with a fitting of the type mentioned at the outset in that each of the two fitting parts is provided with adjusting means for adjusting the distance of the pivot axis of the fitting from a fixed reference point on the fastening means assigned to the relevant fitting part.

This basic design concept of the present fitting is based on the knowledge that it is in no way necessary for the movable sash to be adjusted relative to the fixed frame on the fixed part and thus on the frame or on the fitting part fastened to the frame, because if also an adjustment of the distance between a fen The sash and the fitting part attached to it only when the window is closed, an adjustment of this window sash parallel to the window frame, when the window is open by 90 °, however, an adjustment of this window sash is perpendicular to the window frame, whereas an adjustment of the fitting part attached to the window frame parallel to the window frame in any position of the window sash causes a displacement of the window sash parallel to the window frame, so it is by no means necessary that the adjustment of the window sash relative to the frame to be carried out is parallel and perpendicular to the window frame on the fitting part attached to the frame, because the exact position of the window sash relative to the window frame is only necessary when the window is closed and in this position of the window sash also an adjustment of the distance between the window sash and the fitting part attached to it a displacement of the window terflügels parallel to the window frame. With this knowledge, the adjusting means for adjusting the sash parallel to the frame and the adjusting means for adjusting the sash perpendicular to the frame, which are arranged on one and the same fitting part in the known fitting of the type mentioned, could be distributed to both fitting parts, so that only one of the two adjusting means was to be arranged for each of the two covering parts, and thus the design associated with the arrangement of both adjusting means on one and the same covering part Difficulties could be eliminated.

The main advantage of this fitting is, on the one hand, the reduction in technical effort resulting from the elimination of the aforementioned design difficulties and, on the other hand, the fact that its basic design allows for significant savings in the installation of the fitting by designing the fitting in such a way that it can handle the existing automatic screwing machine can be mechanically mounted on the sash as well as on the frame.

Such a design of the fitting and thus the preferred embodiment of the present fitting results from the fact that the first and second fastening means each have a setscrew which is arranged in the associated fitting part in a rotationally fixed manner and longitudinally displaceable transversely to the pivot axis of the fitting, and the adjusting means of each of the two Fitting parts comprise means for longitudinally displacing the threaded pin assigned to the relevant fitting part in the fitting part, preferably in the form of screw means, and means for fixing the threaded pin in the position set with the longitudinally displacing means. With this design, both fitting parts have such a structure that is comparable with the fittings or fitting parts that were customary in the past, that they can easily be mechanically assembled with the known screwing-in machines and thus compared to the known fitting of the type mentioned at the beginning bring the advantage of significant savings in assembly. The grub screws are mounted in the sash and frame at an angle of 90 ° to each other.

This preferred embodiment of the present fitting can advantageously be designed in such a way that each of the two setscrews for the rotatable longitudinally movable arrangement in the associated sole part is provided at its end facing the part with an end piece which has a circular shape over at least part of its length has a different cross-sectional shape, preferably a square shape or a segmentally flattened circular shape, and that each of the two fitting parts is provided with a corresponding recess for receiving the end piece of the associated threaded pin, which has at least part of its length the same cross-sectional shape that deviates from the circular shape as that of the end piece.

In the case of said preferred embodiment of the present fitting, the longitudinal displacement means can furthermore have a thread in the region of the end of the threaded pin facing the sole part, preferably in the form of the internal thread of a threaded hole let into the threaded pin, and a matching suction bar element, preferably in the form of a head tube, and the fixing means a bore provided in the fitting part and extending in the direction of the threaded pin and receiving at least part of the screw element, preferably the Sohraubenkopf, with an annular shoulder to support one side of the Sohraub element or the part received in the bore as well as an annular groove embedded in its bore wall, into which a snap ring for supporting the other side of the Sohraub element or the part received in the bore and thus to fix the position of the screw element is inserted in the longitudinal displacement direction of the threaded pin. Instead of a cap screw as a screw element and an associated threaded hole in the threaded pin, the thread in the region of the end of the threaded pin facing the fitting part can also be an external thread and the screw element can be a sleeve-like screw ring screwed onto this external thread, which has one end with means for attaching one Screwing tool, preferably with a screw slot, and is preferably closed at this end like a pot. This last-mentioned variant is particularly recommended for relatively small fittings or setscrews of a relatively small diameter, because in such cases using a cap screw as a screw element may result in a diameter that is too small and thus in a too small load-bearing cross section of the cap screw.

A further advantageous embodiment of the longitudinal displacement and fixing means results in the aforementioned preferred embodiment of the present fitting in that the longitudinal displacement means have a thread on the threaded pin in the area of the fitting part facing end of the same and a sleeve-like screw ring screwed onto this thread, which has an external thread with a different pitch compared to the pitch of the thread in the area of the end of the threaded pin facing the sole part and at one end with means for attaching a Sohraubwerkzeuges, preferably with a Sohraubsohlitz, is provided, and further comprise a threaded bore in the base part for screwing in the Sohraubring and the external thread of the Sohraubring together with the threaded bore in the base part simultaneously form the fixing means.

In addition to the adjustability of the sash relative to the frame in the direction perpendicular to the frame and in the direction parallel to the frame and perpendicular to the swivel axis, which can be achieved with the adjusting means already mentioned, in most cases a sash adjustability relative to the frame is also an adjustability of the sash Direction of the swivel tacho required, which is also provided in the known fitting of the type mentioned. However, this does not mean that every fitting according to the present invention should also be provided with adjusting means for adjusting the sash in the direction of the Sohwenkaohse, since sashes such as window and door sashes are usually with two sole pads or one pair of sole pads on the associated frame suspended, and to achieve an adjustability of the wing in the direction of the Sohwenkaohse, it is sufficient if one of these two fittings with adjusting means for adjustment of the wing is provided in the direction of the swivel axis, because such an adjustment on the one fitting inevitably results in a corresponding adjustment on the other of the two fittings, so that this other fitting does not have its own adjusting means for adjusting the wing in the direction of the swivel axis needs to be. This possibility is used in a special embodiment of the present invention, which will be explained in more detail below.

However, the present fitting is preferably provided with additional adjusting means for adjusting the distance between the two points at which the fastening means are attached to the respectively associated fitting part in the direction of the pivot axis of the fitting. These additional adjusting means can advantageously comprise a threaded hole concentric with the pivot axis of the fitting in a first section of the second fitting part, to which the fastening means assigned to the second fitting part are attached, and a second section of the second fitting part provided with a thread that fits into this threaded hole Rotation relative to the first section of the second fitting part can be adjusted relative to the same in the direction of the pivot axis of the fitting and has a cylindrical recess which is arranged concentrically to the pivot axis of the fitting and which is for receiving the pin of the first sole part in the second loading Impact part provided recess, and which further has a support surface for supporting the first fitting part, which is preferably formed by a surface adjacent to one of the two ends of the cylindrical recess, lying in a plane perpendicular to the pivot axis of the fitting, and further by means for attaching a screwing tool, preferably in the form of radial bores provided on a flange-like projection of this second section and distributed on the circumference of the projection. In this first advantageous embodiment of the additional adjusting means, there are in principle two advantageous variants for the formation of the second part of the second fitting part, namely firstly in the form of a sleeve and secondly essentially in the form of a pot. In the case of a sleeve-shaped design, the support surface with which the second fitting part or this sleeve-shaped second section of the same is supported on the first fitting part is the edge of this sleeve-shaped second section of the second fitting part facing the first fitting part, while the design in the form of a pot is the Both fitting parts should expediently be dimensioned such that the pin of the first fitting part is supported on the pot base of the second section of the second fitting part. The design in the form of a sleeve is particularly advantageous if plastic is used as the material for the second section of the second sole part, because plastic is the high surface pressure which usually has a rounded cone at the top in a pot-shaped design on the bottom of the pot, as a rule could not withstand it permanently, and for the same reason, when designing a pot, it is two-way to use metal as the material for the second section of the second fitting part . The use of plastic as the material for the second section of the second fitting part also has the particular advantage that it causes the pin to seize in the recess provided for receiving the same, as was the case with the previously customary fittings due to crevice corrosion between the metallic pin and the the same receiving, also metallic fitting part here and there had been excluded. A second advantageous embodiment of the additional adjusting means differs from the first advantageous embodiment of the additional adjusting means described above in that the additional adjusting means have a threaded pin concentric with the pivot axis of the fitting on a first section of the first fitting part, to which the fastening means associated with the first fitting part are attached , and comprise a second section of the first fitting part provided with a threaded bore fitting this threaded pin, which is rotatable relative to the first section of the first fitting part relative to the same in the direction of the pivot axis of the fitting and which is at least partly from the pin of the first fitting part educated and which further has a support surface for supporting the second fitting part, which is preferably formed by a surface which is attached to one of the two ends of the cylindrical part of the pin, and which further comprises means for attaching a Sohraub tool, preferably in the form of a flange Projection of this second section, provided on the circumference of the projection radial bores, is provided, wherein the threaded hole provided for receiving the threaded pin in the second section is preferably arranged at least partially within the pin. This second advantageous embodiment of the additional adjusting means has the advantage of a very precise guidance of the second section of the first fitting part when it is adjusted compared to the first section on the with a suitable design of the said threaded pin in the form that only part of the pin is provided with a thread non-threaded part of the threaded pin and the additional advantage that the thread of the threaded pin is not visible from the outside. In this second advantageous embodiment of the additional locking means that should the pin-carrying second section of the first fitting part from the already above-mentioned reasons, the high Fl chendruckes ^g- at the site at which the peg of the he: th fitting part on the bottom of the pin supporting receiving recess in the second fitting part, suitably made of metal. In addition to those described above benen two advantageous training forms of the additional actuating means, in which the constructive training of the additional actuating means is particularly simple, other training forms of the additional actuating means with other special advantages are of course also possible. In a further advantageous embodiment of the additional adjusting means, the special advantage that all the adjusting means of the fitting can be adjusted with a screwdriver is achieved in that the additional adjusting means can be displaced in the recess of the second fitting part and displaced in the same in the direction of the pivot axis of the fitting arranged piston, which on its side facing away from the opening of the recess has a flat support surface extending obliquely to the piston axis, an intermediate piece arranged between this support surface of the piston and the plane of the recess lying in a plane extending perpendicular to the pivot axis of the fitting, the with a flat surface rests on the bottom of the recess and with at least one flat inclined surface on the support surface of the piston and by means of which the piston is supported on the bottom of the recess, and one is screwed into a threaded bore in the intermediate piece Used and stored in the second fitting part, provided for the displacement of the intermediate piece transversely to the pivot axis of the fitting and thus for adjusting the piston in the direction of the pivot axis of the fitting, the axis transverse to Sohwenkaohse of the fitting runs and lies in the same plane, in which there is a connecting line between the most distant points of the support surface of the piston and the pivot axis of the fitting, and that the depth of the piston which extends to the side of the piston facing the opening of the recess Recess in the piston position with the greatest depth of the recess is smaller than the height of the pin provided on the first base part, so that the pin is supported on the piston in each piston position, and that the pin is preferably spherical at its end facing the piston and the piston on its side facing away from the opening of the recess is preferably provided with a cross-sectionally T-shaped recess which runs along the said connecting line and into which a corresponding T-shaped socket piece arranged on the intermediate piece engages.

Another possibility for the formation of the additional adjusting means results from the above-mentioned Saoh behavior that it is sufficient to achieve an adjustability of the wing in the direction of the Sohwenkaohse if one of the two fittings with which a wing is usually pivotally attached to the associated frame , is provided with adjusting means for adjusting the wing in the direction of the Sohwenkaohse, because such an adjustment on the one soleplate inevitably also means a corresponding adjustment on the other of the two fittings. In principle, therefore, in any case, in the case of two fittings assigned to one another to be attached to the same sash, a first fitting is a fitting according to the present invention without additional adjusting means for adjusting the sash in the direction of the pivot axis and the second fitting is a fitting according to the present invention with additional adjusting means for adjusting the wing in the direction of the pivot axis, the ability to adjust the wing relative to the frame in all three spatial directions. An almost equivalent possibility also arises, however, if of two associated fittings to be attached to one and the same sash, a first fitting is a fitting according to the present invention without additional adjusting means for adjusting the sash in the direction of the pivot axis and the second fitting is a fitting , in which one of the two fitting parts is designed in the same way as the corresponding fitting part of the first fitting and the other fitting part only has adjusting means for adjusting the sash in the direction of the pivoting eye and with that of the two parts frame and sash to which it is fastened, firmly and is immovably connected. With this last-mentioned possibility, the adjustability of the sash relative to the frame in that of the three spatial directions, for which no adjusting means are provided in the said other fitting part of the second fitting, for an alignment of the sash exactly parallel to the frame men, that is to say eliminating an inclination of the wing relative to the frame, but in the vast majority of cases this is completely sufficient in practice, so that the latter possibility is practically equivalent to the former option in practice. The present invention therefore also relates to a pair of coverings of two associated coverings to be attached to one and the same wing, of which a first cover is a cover according to the present invention without additional adjusting means for adjusting the wing in the direction of the pivot axis and the second fitting is a first Fitting part with fastening means and adjusting means roughened thereon, which, like one of the two fitting parts of the first fitting, is designed with the fastening means and adjusting means attached to it, and a second sole part, which with the counterpart of the element provided for the first fitting part of the second fitting, of the two Elements pin and pair of elements provided for receiving the pin is provided, and further comprises fasteners attached to the second base part of the second fitting, wherein it is characteristic of the base pair that the on the second Fitting part of the second fitting attached fastening means are fixed and immovably connected to this second fitting part relative to this second fitting part and the second sole part of the second fitting adjusting means for adjusting the distance between the two Positions from each other at which the fastening means of the second fitting are attached to the respectively assigned fitting part, in the direction of the pivoting axis of the second fitting, and these adjusting means comprise a threaded hole in the second fitting part of the second fitting that extends in the direction of the pivot axis of the second fitting, which up to to the duros point of the pivot axis of the second fitting through the fitting end of the second fitting associated with the second fitting part, and a screw element screwed into this threaded bore for adjusting the said distance, which at its end facing said fitting end with means for attaching a screwing tool, preferably with a Screw slot is provided. The advantage of this pair of fittings is that the constructive means for adjusting the sash in the direction of the pivot axis are even simpler than the above-mentioned additional adjusting means used for this purpose in the above-described forms of the fitting according to the invention, and that the adjustment of the sash is relative can be done with a setting of only four instead of six setting points - which is very important in practice, since the various setting points usually have to be adjusted several times before the correct setting is found, and with a larger number of Difficulties to find the right attitude - and that Finally, the adjustment of the sash relative to the frame at all four positions can be done with one and the same Sohraubie tool, namely a Sohraubenzieher, which is also of some importance in practice for the smallest possible circumstances when adjusting the sash relative to the frame.

Fig. 5a-5o a fifth embodiment of a fitting according to the invention, which is provided with additional adjusting means for adjusting in the direction of the pivot axis in the form of a piston arranged in the recess in the second fitting part, adjustable by a set screw, with a first fitting part together with the associated fastening - And adjusting means in partial longitudinal section in Fig. 5a and the second Besohlagteil including associated fastening and adjusting means in partial longitudinal section in Figures 5b and 5o

A basic form of the present fitting is shown in FIGS. 1a to 1f. In its basic form, the fitting consists of the first base part 1 to be attached to the frame, which is provided with a pin 2. Meanwhile, the axis forms the pivot axis 3 of the fitting, a second side part 4 to be attached to the wing, which is one for Receiving the pin provided recess 5 has first and second attachment means in the form of the setscrews 6 and 7 of the same design for fastening the first fitting part 1 to the frame and the second fitting part 4 to the sash and adjusting means for adjusting the sash parallel and perpendicular to the frame, which the two adjusting screws 8 and 9 and the two snap rings 10 and 11 include.

The setscrews 6 and 7 are arranged in the associated fitting parts 1 and 4 in a rotationally fixed manner and longitudinally displaceable transversely to the pivot axis 3 and are provided with an end piece in the form of a square 12 and 13 at their end facing the fitting part 1 and 4, respectively a recess 14 or 15, which is provided in the associated fitting part 1 or 4 for receiving the end piece and has a square cross section, is arranged to be longitudinally displaceable in the sliding fit.

For the longitudinal displacement of the setscrews 6 and 7 in the associated fitting part 1 or 4 transversely to the pivot axis 3, the set screws 8 and 9 are used in conjunction with the threaded holes 16 and 17 provided in the set screws 6 and 7, into which the set screws 8 and 9 are screwed . So that the setscrews 6 and 7 or the fixed reference points 18 and 19 not only move on the same when tightening the set screw 8 or 9 on the pivot axis 3 but also when the adjusting screw 8 or 9 rotates in the opposite direction in the opposite direction are, the adjusting screws 8 and 9 are gesi against longitudinal displacement ohher that her Sohraubenkopf 20 or 21 on the one hand through the ring holder 22 or 23 of the bore 24 or 25 receiving the screw head and on the other hand through the snap ring 10 or respectively inserted into the annular groove 26 or 27 in the wall of the bore 24 or 25 11 is fixed in its position. Duroh this fixation of the position of the screw head 20 and 21 and thus the set screw 8 and 9, the grub screw 6 and 7, in the threaded bore 16 and 17, the set screw 8 and 9 is screwed in its position in the the set screw 8 or 9 set position.

Instead of the set screws 8 and 9 and the associated threaded bores 16 and 17 in the threaded pins 6 and 7, it is of course also possible to have an external thread on the said end pieces of the threaded pins 6 and 7 (which in the exemplary embodiments shown in the drawings are square 12 and 13, respectively ) and a sleeve-shaped Sohraubring screwed onto this external thread should be provided, although in this case the end pieces of the setscrews should not be square in cross-section but should be essentially circular, and to achieve the required torsional strength of the set screws, this circular shape should be at least part of the total length of the end pieces should be flattened in segments because, for an external thread, a cross-section in a circular shape or a segment-shaped flattened circular shape is more advantageous than a cross-section in a square shape. The Sohraubring can either be like one The ring nut must be cylindrical on the outside, in which case the hole that receives the screw ring must also be made cylindrical and, on the one hand, an annular shoulder and, on the other hand, an annular groove with an inserted snap ring must be provided in order to secure the screw ring against longitudinal displacement in this hole, or else an external thread is provided on the screw ring with a corresponding internal thread provided by the external thread on the end piece of the threaded pin and in the bore receiving the screw ring, in which case the latter secures the screw ring against longitudinal displacement of the internal thread of the bore receiving the screw ring in cooperation with the external thread on the screw ring is taken over and other means for this purpose such as the above-mentioned ring groove with inserted snap ring and the ring shoulder of the bore receiving the Sohraubring are not required.

Furthermore, other fastening means can of course also be provided instead of the threaded pins 6 and 7, but with the threaded pins there is precisely the essential advantage that the fitting parts 1 and 4 with the existing screwing-in devices already mentioned, both mechanically on the sash and on the frame can be assembled and thereby substantial savings can be achieved in the assembly of the fitting, so that the use of fastening means other than set screws in principle within the scope of the present invention is only for Special cases such as those cases in which automatic assembly machines are also already available for the fastening means to be used. It is essential, however, that for the fittings according to the present invention, set screws which are better adapted to the practical requirements than the set screws provided for the fittings belonging to the prior art can be used. In principle, this is due to the following: If a fitting part is screwed into a sash or frame with a grub screw, then it must have a very specific angular position at the end of the screwing-in process. For example, the pin of a base part screwed into the frame must point vertically upwards after the screwing-in process. This means, however, that during the screwing-in process in which the fitting part is to be brought into a certain prescribed position, compared to the average number of revolutions of the threaded pin or the fitting part during the screwing-in process required for this, only one full turn less or more can be made by the prescribed To reach the position as precisely as possible, but not just a fraction of a turn with which one could reach the prescribed position very precisely. In order nevertheless to ensure that the prescribed position is reached at least as precisely as possible, the setscrews in the fitting parts belonging to the prior art were provided with a thread of a relatively small pitch so that the pos tion displacement at the full rotation mentioned was not too great and, for example, with a thread pitch of 0.8 mm, the prescribed position could be reached with an accuracy of 0.4 mm. This thread of a relatively small pitch in the threaded pins of the fittings belonging to the prior art, however, had the natural part that, according to the small thread pitch, the thread depth of the thread of the threaded pins had to be kept small (for example, as in the case of a fine thread of a metal cap), and that thereby Durability of the grub screws in the sashes and frames, which are mostly made of wood, was adversely affected, because it is known that a metal screw screwed into wood with a fine thread can be torn out of the wood with a relatively low tensile force. In the fittings according to the invention, on the other hand, grub screws with a relatively large pitch and correspondingly large thread depth can be used without further ado because, in the case of the coverings according to the invention, the pre-drilled position of the fitting part with the adjusting means assigned to the fitting part for adjusting the fitting part relative to the assigned threaded pin can be adjusted very precisely and therefore the requirement for a small thread pitch of the threaded pins can be dispensed with in the fittings according to the invention.

FIGS. 2a to 5o now show a number of exemplary embodiments, such as that in the figures 1a to 1f shown basic form of the present fitting with additional adjusting means for adjusting the distance between the two points at which the threaded pins 6 and 7 are attached to the respectively assigned fitting part can be provided in the direction of the pivot axis of the soleplate. In this context, it should be pointed out again that of two fittings with which a wing is pivotally attached to a frame, only one needs to be provided with such additional adjusting means for adjustment in the direction of the pivot axis, while the other fitting has the one shown in FIGS to 1f can have the basic shape shown (in which no such adjusting means are provided for adjustment in the direction of the Sohwenkaohse), but of course both fittings can also be provided with such additional adjusting means for adjustment in the direction of the pivot axis (which may be more advantageous for reasons of standardization and storage can). With regard to FIGS. 2a to 5c, it should also be generally pointed out that the adjusting means for adjusting the setscrews in the exemplary embodiments of the present fitting shown in these figures are designed in the same way as in the basic form of the present fitting shown in FIGS. 1a to 1f and in These exemplary embodiments in this regard also have the same possible variations as described above for the basic form. Therefore, for the exemplary embodiments shown in FIGS. 2a to 5c, only the additional positioning means are described below described for adjustment in the direction of the Sohwenkaohse dee fitting.

In the exemplary embodiments shown in FIGS. 2a and 2b and 3a and 3b, these additional adjusting means for adjustment in the direction of the Sohwenkaohee consist in a threaded bore 28 or 29 concentric with the Sohwenkase 3 of the fitting in a first section 30 or 31 of the second sole part 32 or 33, on which the threaded pin 7 assigned to the second covering part 32 or 33 is attached, and a second part 36 or 37 of the second fitting part 32 or 33 provided with a thread 34 or 35 which fits into this threaded bore 28 or 29 which can be adjusted relative to the first section 30 or 31 of the second fitting part 32 or 33 relative to the same in the direction of the pivot axis 3 of the fitting and which has a cylindrical recess 38 or 39 which is arranged concentrically to the pivot axis 3 of the fitting and which provided for receiving the pin 40 or 41 of the first fitting part 42 or 43 in the second fitting part 32 or 33 eh recess forms, and which further has a support surface 44 or 45 for supporting the first Besohlagteiles 42 and 43, which from one of the two ends of the cylindrical recess 38 and 39 adjoining, in a perpendicular to the Sohwenkaohse 3 of the fitting Flat surface is formed, and further with means for attaching a Sohraub tool in the form of a flansoh Like projection 46 and 47 of this second part Stüokes 36 and 37 provided, provided on the circumference of the projection 46 and 47 distributed radial bores 48 and 49 respectively. In the exemplary embodiment shown in FIGS. 2a and 2b, the second section 36 of the second fitting part 32 consists of a plastic sleeve provided with an external thread 34 of a length slightly greater than the length of the pin 40 of the first fitting part 42, so that the first fitting part 42 can under no circumstances be supported with the pin 40 on the bottom of the threaded bore 28 of the first section 30 of the second fitting part 32, but in any case is supported on the support flute 44 of the second section 36 of the second fitting part 32 and therefore upon rotation of the second section 36 of the second Fitting part 32 relative to the first section 30 of the same in any case an adjustment of the distance between the threaded pins 6 and 7 in the direction of the pivot axis 3. The advantage of this exemplary embodiment shown in FIGS. 2a and 2b is that the plastic sleeve forming the second section 36 of the second fitting part 32 makes contact of the first fitting part 42, which is generally made of metal, with the first section 30, which is also generally made of metal excludes second fitting part 32 and thus prevents the fitting from seizing due to corrosion. So that during the opening and closing of a window, for example, the rotation of the second covering part relative to the first does not result in the plastic sleeve 36 in the threaded bore 28 rotates (which would cause an undesired adjustment), the thread 34 must be held relatively securely in the threaded bore 28, if necessary by introducing appropriate means such as, for example, the plastic tapes used between the thread 34 and the threaded bore 38 for sealing screw connections in water pipes, and for the same reason it is also advisable to use a plastic with the lowest possible coefficient of static friction for the plastic sleeve 36. In the embodiment shown in FIGS. 3a and 3b, the cup-shaped second section 37 of the second sole part 33 is made of metal, and there the length of the cylindrical recess 39 provided for receiving the pin 41 of the first fitting part 41 is a little smaller than the length of the Pin 41, so that the pin 41 is supported with the central region of its rounded upper end 50 on the bottom of the recess 39 serving as support surface 45 in this exemplary embodiment. Since the pin 41 is in principle only supported on one point of the support surface 45 and therefore practically no torque can be transmitted to the support surface 45 when it rotates with respect to the support surface 45 and the bearing formed by the pin 41 and the recess 39 is also greased, In the embodiment shown in FIGS. 3a and 3b, there is hardly any risk that when the second base part rotates relative to the first, the cup-shaped second section 37 of the second fitting part 33 is in the threaded bore 29 of the first section 31 of the second loading Soblagteil 33 rotates, but regardless of this, a relatively tight fit of the thread 35 in the threaded bore 29 is advantageous here, and daegleiohe also applies in a corresponding manner to the embodiment described below, shown in Figures 4a and 4b. An advantage of the exemplary embodiment in FIGS. 3a and 3b is that the cylindrical shoulder 51 on the cup-shaped second section 37 of the second fitting part 33 and the matching cylindrical bore section 52 in the first section 31 of the second sole part 33 ensure that the thread 35 is not visible from the outside.

In the exemplary embodiment shown in FIGS. 4a and 4b, the additional adjusting means for adjustment in the direction of the pivot axis consist of a threaded pin 53 concentric with the pivot axis 3 of the fitting on a first section 54 of the first fitting part 55, on which the threaded pin 6 assigned to the first fitting part 55 is attached, and a second bore 57 provided with a threaded bore 53 matching this threaded pin 53 of the first fitting part 55, which is rotatable relative to the first part 54 of the first fitting part 55 in relation to the same in the direction of the pivot axis 3 of the fitting and at least is partly formed by the pin 58 of the first fitting part 55 and which further has a support surface 59 for supporting the second fitting part 60, which extends from the end of the cylindrical part 61 of the pin 58 is formed on the surface, and which is further provided with means for attaching a Sohraub tool in the form of a flange-like projection 62 of this second part sleeve 57, distributed over the circumference of the projection 62, radial bores 63, which for receiving the threaded pin 53 in the second part 57 provided threaded hole 56 is arranged inside the pin 58 and the threaded pin 53 as well as the threaded hole 56 are cylindrical over part of their length, which results in very good guidance of the second part 57 on the first 54 and the additional Advantage that the thread of the threaded pin 53 is not visible from the outside.

In the exemplary embodiment shown in FIGS. 5a to 5o, the additional adjusting means for adjustment in the direction of the pivot axis 3 of the fitting consist of a piston 66 which fits into the recess 64 of the second fitting part 65 and is displaceable therein in the direction of the pivot axis 3 of the fitting has a flat support surface 67, which extends obliquely to the piston axis, an intermediate piece 69 arranged between this support surface 67 of the piston 66 and the bottom 68 of the recess 64, which has a flat surface 70 on the bottom 68 of the recess 64 and two flat inclined surfaces 71 on the Support surface 67 of the piston 66 abuts and via which the piston 66 is supported on the bottom 68 of the recess 64, and one in a Threaded bore 72 screwed into the intermediate piece 69 and mounted in the second base part 65, for screwing the intermediate piece 69 transversely to the pivot axis 3 of the fitting and thus for adjusting the piston 66 in the direction of the pivot axis 3 of the fitting, provided adjusting screw 73. The adjusting screw 73 is arranged in this way that its axis 74 extends transversely to the pivot axis 3 of the fitting and lies in the same plane in which the main axis of the ellipse formed by the support surface 67 of the piston 66 or a connecting line between the most distant points of the support surface 67 of the piston 66 and the pivot axis 3 of the fitting. The piston 66 is provided with a recess 75, which is T-shaped in cross-section and runs along this main axis or this connecting line, into which a corresponding T-shaped rail bush 76 arranged on the intermediate piece 69 engages. By means of this socket piece 76 on the one hand and the adjusting screw 73 on the other hand, the intermediate piece 69 is guided transversely to the socket sleeve 3 of the fitting when the adjusting screw 73 is rotated. The T shape serves to ensure that the piston 66 is carried by the intermediate piece 69, so that it cannot fall down out of the recess 64. The depth 77 of the recess 64 is in the piston position, in which the greatest depth 77 results, a little smaller than the height of the pin 79 provided on the first sole part 78, so that the pin 79 is in each piston position on the Piston 66 is supported. The pin 69 is spherical at its end facing the piston 66 and is therefore supported in the same way as in the exemplary embodiments in FIGS. 3a and 3b and 4a and 4b in principle only at one point or a punctiform surface on the piston 66 . The advantage of the exemplary embodiment shown in FIGS. 5a to 5o lies mainly in the fact that all adjustments are carried out with set screws and can therefore be carried out with a screwdriver and the setting mechanism, as in the exemplary embodiments in FIGS. 3a and 3b as well as 4a and 4b, is not from the outside is visible. It should be noted in this connection that FIG. 5o represents a part of FIG. 5b in the son plane II and FIG. 5b in turn represents a section of FIG. 5o in the plane II-II.

All of the exemplary embodiments described above and shown in the drawings also have the common advantage that the fittings can be fitted both on the right and on the left side of the wing, which is particularly important for storage. In the exemplary embodiment in FIGS. 5a to 5o, this advantage is achieved in that the adjusting screw 73 in FIG. 5o is screwed in either from the right or from the left and, in the case of a single-eared cap in FIG. 5o, the piston 66 with the intermediate piece 69 is rotated by 180 ° with respect to the position shown in FIG. 5o.
