Description

The invention relates to a hinge fitting for the sash of windows, doors or the like. With hinged hinges on the fixed frame, attached to the sash hinges, in which the attachment consists of a fitting which is positively in an undercut, for example in cross-section C or dovetail-shaped Profile groove of a wing leg insertable and position-adjustable in its longitudinal direction on an actuator in the wing, for example is supported by screws, a fixed stop, with a shaped and open window-like cutout being provided in the fitting, in which the wing-side fixed stop engages in a relatively displaceable manner in the longitudinal direction, the cutout on the one hand and the stop on its longitudinal walls on the other in certain areas has interrupted guide strips which can be brought into engagement with one another transversely to the direction of action of the actuator and can be fixed in their mutual engagement position by the actuator, and wherein the actuator is designed as a screw which can be screwed into the cutout through the end wall of the shaped piece.

A hinge fitting of this type is part of the prior art, for example, by DE-U-76 36 855 and has been used there in particular on opening devices for the sash of tilt-and-turn windows, doors or the like, which have a fixed frame in the region of the pivot axis of the Wing are only pivotally mounted, pivotable and slidably engaging extension arm and equipped with an additional arm on the one hand on the extension arm and on the other hand only pivotally mounted on the wing, the sliding guide for the extension arm and the storage for the additional arm are located on the shaped piece designed as a profile rail.

There is also the possibility of using a generic hinge fitting for swing-wing windows and doors, for bottom-hung windows and for folding-wing windows, if the connection of the hinges to the wing takes place within the meaning of DE-U-1 961 913, i.e. the hinges are connected at an intermediate angle is directly connected to the fitting.

A hinge fitting similar to DE-U-76 36 855 for opening devices of tilt-and-turn windows, doors or the like is also known from DE-U-77 21 479.

In all these known hinge fittings, it is disadvantageous that a special engagement hole must be drilled in the bottom of the profile groove of the wing leg for the installation of the fitting supporting the set screw against the wing, to accommodate a peg-like extension, the stop in its installation position fixed securely on the wing leg.

The easiest way to mount the hinge fitting according to the generic DE-U- 76 36 855 wing side, because it is possible there to insert the fitting and the stop together in the undercut profile groove of the wing leg and only then arranged in the form of a screw in the stop Screw the pin into the engagement hole in the profile groove of the wing leg.

Such a simple assembly, however, cannot be carried out according to DE-U-1 961 913 and DE-U-77 21 479. Rather, it is necessary there to mount the stop provided with a fixed pin separately from the fitting in the area of the engagement hole in the profile groove of the wing leg and only then to establish the operative connection with the fitting.

All these known hinge fittings have the disadvantage in common that their attachment to the wing for right or left hinges causes a considerable amount of work because here screw connections are loosened and restored between the joint hinges and the intermediate links used to connect them to the fitting for the purpose of carrying out the changeover process must, as is obvious with the hinge fitting according to DE-U-1 961 913 or also with the hinge fitting according to DE-U-77 16 365.

The aim of the invention is to provide a hinge fitting of the type specified at the outset which does not have the disadvantages of the known hinge fittings dealt with above. Therefore, the invention has for its object to provide a hinge fitting that not only ensures a simple and problem-free attachment to the wing, but also allows the adjustment to the right and left stop without further ado, thus avoiding loosening and tightening of screw connections.

This goal is achieved according to the invention in that the hinge strap can be connected to the fitting exclusively by a positive plug-in coupling, the first coupling half of which is formed by recesses and projections provided on the underside of the fitting, while the second coupling half consists of one of the hinge strap normal to the hinge axis protruding tab, which in the direction parallel to the hinge axis has a complementary to the recesses and projections of the molding, and that both coupling halves of the plug-in coupling are designed symmetrically to their longitudinal center.

All of the functional parts essential for the formation of the hinge fitting, i.e. the hinge, the fitting and the stop, can be easily inserted in the longitudinal direction into the undercut profile groove of the wing limb in question, and are then simply tightened fixed by stop screws in this profile groove on the wing leg. In this installation process, it is then only necessary to ensure that the hinge is connected to the fitting via the positive plug-in coupling in accordance with the intended stop direction.

For the optional right and left stop of the hinge fitting, it is also important that according to the invention the flap forming the second coupling half is arranged on a plane of symmetry crossing the hinge axis of the hinge and the profile extends uniformly over its entire thickness. By simply turning the hinge strap through 180 °, it can be put together with the fitting for right or left stop.

For sufficient stability of the hinge fitting, it is also important that the mutual engagement depth of both coupling halves of the plug-in coupling extends at least over the maximum profile depth of the undercut profile groove in the wing leg, while their maximum mutual engagement width is matched to the clear opening width of the undercut profile groove. The coupling half of the plug-in coupling provided on the hinge can in this embodiment also directly enter into an active connection with the wing leg by not only supporting it on the bottom of the undercut profile groove, but also between the mutually facing surfaces of the undercuts of the profile groove delimiting hook webs Wing leg engages.

It has proven to be advantageous if the recesses and projections forming the first coupling half of the plug-in coupling are provided on the shaped part in the region of the upright legs of the foot parts which undercut the undercut parts of the profile groove of the wing leg, approximately L-shaped profiled foot parts, while those which form the second coupling half Profiling of the flap on the hinge is formed by alternating lugs and indentations on the longitudinal edges.

A further stabilization of the form-fitting plug-in coupling can be brought about according to the invention in that a longitudinal center, e.g. protrudes in cross section round pin, which is assigned a correspondingly profiled hole in the tab of the hinge.

Another important further development feature of the hinge fitting according to the invention is that the shaped piece in its - middle - length range between the first coupling half for the plug-in coupling and the window-like cutout is offset both on its underside and on its long sides and there longitudinal guide receptacles for forms a section of the stop, which is provided on the one hand along its underside with laterally protruding foot parts for gripping under the undercut parts of the profile groove of the wing leg, while on the other hand it carries threaded eyes protruding sideways at a distance above these foot parts on projecting guide webs, in which above the undercut parts of the profile groove of the wing are threaded fastening bolts. These fastening threaded bolts can each carry a pin-like punching attachment at their shaft start. When tightening the fastening screw in question, this punching lug is pressed through the inwardly directed leg of the profile webs, which delimit the undercut profile groove on the wing leg. The stop is then positively fixed in position in the punched cut-out which is created by means of the fastening threaded bolts.

According to the invention it is provided that only one group of guide strips is assigned to the end of the stop engaging in the window-like cutout of the shaped piece, while a second group of guide strips is located at the other end of the stop and on the two remote long sides of the fitting is located. It has been shown that these training measures significantly facilitate the assembly of the fitting and the stop and, in particular, result in a good guide quality if both groups of guide strips on the stop and on the fitting are at least approximately at the same height.

In the simplest case, according to the invention, the second group of guide strips can each be formed by mutually directed lugs or tongues, which are located on the outer sides of the stop and the fitting.

For the problem-free assembly of stop and fitting, it has also proven to be advantageous if the screw forming the actuator has a mushroom head on its end protruding into the window-like cutout of the guide piece, which can be placed in a form-locking engagement with an approximately C-shaped end opening of the stop is when stop and fitting are brought together to produce the mutual engagement of the guide strips.

In terms of operation, it is particularly advantageous for the adjustment of the hinge fitting relative to the sash if the screw forming the actuator assumes an axial position in the end wall of the fitting which is inclined towards the horizontal. It is then easily accessible with a screwdriver or a wrench. Proper attachment of the hinge fitting to the respective wing leg of the window, the door or the like can be facilitated if, according to the invention, the alignment or stop lugs which protrude above the underside of the foot parts and which are adjacent to the plug coupling for the hinge band are provided with predetermined breaking points. The basic position of the stop relative to the fitting should also be determined in at least one direction of adjustment of the screw forming the actuator by stops provided with predetermined breaking points. It is then ensured in a simple manner that the stop of the hinge fitting on his Fastening threaded bolt is fixed in a very specific basic position on the respective wing leg of the window, the door or the like. Only if the hinge fitting needs to be adjusted from the predetermined basic position by corresponding actuation of the screw serving as an actuator, are the predetermined breaking points severed and thereby release the necessary travel of the fitting relative to the stop or to the sash.

It has also proven to be important according to the invention that the end of the fitting forming the first coupling half of the plug-in coupling for the hinge protrudes beyond the fold edge of the wing extending transversely to its insertion direction as a support stop for the flap of the hinge. The flap of the hinge can therefore not bend undesirably under the influence of the weight of the opened wing.

An embodiment of the object of the invention is explained in more detail with reference to drawings.

a partial overview of a casement window, which is equipped at the upper right corner between the sash and the fixed frame with a hinge fitting according to FIGS. 1 to 5.

1 to 5 of the drawing, a hinge fitting 55 for windows, doors or the like is shown, which is used according to FIG. 6 of the drawing as an upper hinge fitting 55 of a casement window 51 and there for mounting the wing 53 on the fixed frame 52 serves.

The lower hinge fitting 54 of the casement window 51 according to FIG. 6 has a conventional design and therefore does not need to be explained in more detail.

The upper hinge fitting 55 according to FIG. 6 has a frame-side hinge band 56 with a hinge sleeve 57 located in front of the face-side end face of the fixed frame 52, into which a hinge pin 58 engages. This hinge pin 58 is encompassed above the hinge 56 by the hinge sleeve 59 of another hinge 60, which is connected to a fitting 61 which can be attached to the upper horizontal leg of the wing 53, as can be seen in FIG. 6. For this purpose, the shaped piece 61 has integrally formed on its lower longitudinal edge, laterally ledge-like projecting foot parts 63, with which it can be inserted from the corner of the wing 53 into an undercut, for example C-shaped, profile groove 62, which leads to the wing corner is cut open. The arrangement and design of the profile groove 62 in the legs of the wing 53 can be seen in particular from FIG. 3 of the drawing.

The fitting 61 is provided in its end wall 64 with an internal thread 65, as can be seen in particular in FIGS. 2 and 5. Doing so in this internal thread 65, a screw 66 is received as an actuator, as can be seen in FIGS. 1, 2, 4 and 6.

At its end located outside the end wall 64 of the shaped piece 61, the screw 66 is provided with a tool engagement, for example a hexagon socket, while its other end projects into a window-like cutout 67 of the shaped piece and is shaped into a mushroom head 68. 2, 5 and 6 of the drawing it can be seen that the internal thread 65 and consequently also the screw 66 seated therein has an axis position which is inclined towards the horizontal, namely for this purpose at an acute angle 69 (FIG. 2). Via its mushroom head 68, the screw 66 is in positive engagement with an approximately C-shaped head piece 70 of a stop 71, which is inserted into the window-like cutout 67 of the shaped piece 61 from below, as can be seen particularly clearly from FIG. 2. The head piece 70 of the stop 71 has lateral wings 72 (FIGS. 1 and 4), which come into operative connection in the window-like cutout 67 of the shaped piece 71 with guide strips 73, which end at a distance from the end wall 64 and on which the window-like cutout 67 is delimited Side walls of the molding 61 are formed (Fig. 5).

In the position of the head piece 70 shown in FIG. 2, its lateral wings 72 lie above the upper edge of the guide strips 73 and can consequently be brought into engagement with the latter by appropriate adjustment of the screw 66.

Since the screw 66 serving as an actuator interacts positively via its mushroom head 68 with the approximately C-shaped head piece 70 of the stop 71, both tensile and compressive forces can be absorbed between the shaped piece 61 and the stop 71.

Over a middle length region 74, the shaped piece 61 is not only cut out on its underside approximately over half its height, but it is also has lateral shoulders over a somewhat larger length range 75, so that only a relatively low and narrow longitudinal web 76 remains there. In the area of this longitudinal web 76, the shaped piece 61 forms longitudinal guide receptacles for a partial section of the stop 71 which encompasses and encompasses it, which, according to FIG. 3, has an approximately H-shaped cross section and is provided along its lower edge with foot parts 77 projecting sideways, which in a similar manner how the foot parts 63 of the shaped piece 61 can engage under the undercut parts of the profile groove 62 in the wing spar in a form-fitting manner. At a distance above these foot parts 77, externally projecting threaded eyes 79 are integrally formed on towering guide webs 78 of the stop 71. In each of these threaded eyes 79, a fastening threaded bolt 80 is received, which can be clamped against the hook webs, which delimit the undercut areas of the profile groove 62 in the wing spars. Each fastening threaded bolt 80 has in each case a pin-like punching projection 81 at its shaft start, which penetrates into the horizontal leg of a hook web and separates a section of material therefrom, in order to subsequently form-fit in the cutout formed thereby.

From Fig. 5 of the drawing it can be seen that each outside of the longitudinal web 76 of the fitting 61 gripping guide web 78 of the stopper 71 is provided near its upper edge with a projecting tongue 82, the lower edge of which comes to lie at the same height as the upper edge of a nose 83 , which projecting the molded piece 61 is formed laterally. Tongues 82 and lugs 83 interact with one another as a second group of guide strips between the shaped piece 61 and the stop 71. This in such a way that the superimposed support surfaces of both groups of guide strips assume approximately the same height from the underside of the shaped piece 61. In this way, both the front and the rear end of the stop 71 are provided with a longitudinally movable guide connection with the shaped piece 61. With the aid of the element forming the actuator, it can be moved beyond the area of longitudinal displacement Screw 66, the relative position of the fitting 61 with respect to the stop 71 can be adjusted continuously, provided the stop 61 is anchored via its fastening threaded bolts 80 in the hook webs of the wing spar delimiting the profile groove 62.

An essential design feature of the hinge fitting 55 also lies in the fact that the hinge strap 56 can only be connected to the fitting 61 by means of a form-fitting plug-in coupling 84 (FIG. 4). The first coupling half 85 of this plug-in coupling 84 is formed by recesses 86 and projections 87 provided on the underside of the shaped piece 61, which are alternately adjacent to one another in the longitudinal direction of the shaped piece 61. In this case, recesses 86 and projections 87 are assigned to the two longitudinal edges of the shaped piece 61 symmetrically with respect to the longitudinal center plane thereof, which extends parallel to the wing plane.

As the second coupling half 88 of the form-fitting plug-in coupling 84, a tab 89 protruding from the hinge band 60 normal to its hinge axis is used, which in the direction parallel to the hinge axis of the hinge band 60 has a profile 90 that is complementary to the recesses 86 and projections 87 of the first coupling half 85. 4 of the drawing, the flap 89 has an approximately cruciform outline, so that it fits with its profiling 90 without play in two adjacent notches 86 and between two adjacent projections 87 of the first coupling half 85. It is important that the tab 89 forming the second coupling half 88 is arranged on the hinge band 60 on a plane of symmetry crossing its hinge axis (FIG. 6) and that the profiling 90 extends uniformly over its entire thickness. By simply turning the hinge strap 60 through 180 °, this can be brought into holding engagement with the fitting 61 either for the right-hand stop or for the left-hand stop via the form-fitting plug-in coupling 84, as is indicated in the drawing on the one hand by solid lines and on the other hand by dash-dotted lines.

After the hinge band 60 is then inserted together with the shaped piece 61 into the undercut profile groove 62 of the wing leg, the tab 89 is not only supported (as shown in FIG. 2) on the bottom of the profile groove 62, but it is also over the Total height of this profile groove 62 between the mutually facing surfaces of the bordering hook webs added.

The recesses 86 and projections 87 forming the first coupling half 85 of the plug-in coupling 84 are provided on the shaped part 61 in the region of the upright legs of the foot parts 63 which undercut the undercut parts of the profile groove 62 of the respective wing leg, while the second coupling half 88 forms the second coupling half 88 Profiling 90 of the flap 89 on the hinge band 60 is formed by alternating lugs and indentations on the longitudinal edges thereof, as can be clearly seen in FIG. 4.

To further stabilize the form-fitting plug-in coupling 84, it can also be advantageous to have a pin 91, for example with a round cross-sectional shape, protrude longitudinally from the underside of the shaped piece 60 and to which a correspondingly profiled hole 92 in the tab 89 of the hinge strap 60 is assigned.

5 and 6 of the drawing it can still be seen that at the end of the shaped piece 61, which is adjacent to the plug-in coupling 84 for the hinge strap 60, there are alignment or stop lugs 93 projecting beyond the base parts 63. This can ensure that the stop 71 coupled to the fitting 61 is fixed in the correct basic installation position of the wing 53. After the fastening threaded bolts 80 of the stop 71 assume their engagement position on the wing, it is possible to overcome the alignment or stop lugs 93 of the fitting 61 by correspondingly actuating the screw 66 serving as an actuator and to break them off in the area of a predetermined breaking point 94. The basic position of the Stop 71 relative to shaped piece 61 can be fixed in a simple manner by stops (not shown) which are also provided with predetermined breaking points and which can be overcome or broken off when screw 66 is turned.

2 and 6 of the drawing finally shows that the first coupling half 85 of the coupling 84 for the hinge 60 forming end of the fitting 61 over the transverse to its insertion direction of the folding edge of the wing 53 as a support stop for the tab 89 of The hinge strap 60 can protrude, so that the installation position of the hinge strap 60 relative to the wing 53 is considerably stabilized.
