Description

Hinged plates for doors, windows and the like

The invention relates to a hinge plate for doors, windows and the like of the type stated in the preamble of claim 1 .

Hinge plates for doors, windows or the like made of aluminum or plastic usually comprise a base body made of extruded aluminum profile or die-cast zinc. The hinge plate has mutually parallel upper and lower sides, which are partly determined by production, and which lie horizontally opposite each other in the installed position. The (door or window) leaf in all cases needs to be adjusted in the frame opening after installation, that is to say in the horizontal direction, in the vertical direction and in the direction perpendicular to the plane of the frame or perpendicular to the plane of the leaf parallel to the plane of the frame when the leaf is closed direction adjustment. Numerous embodiments are known for this adjustment, wherein, for specific adjustments perpendicular to the plane of the frame or the plane of the fan, arrangements have always been made in which the position of the hinge plate pin is changed relative to a pivot element. The oldest arrangements of this type are, for example, eccentric bushings according to DE-GM 73 09 196 and double eccentric bushings which have been further developed from this. However, the cost of such a double eccentric sleeve is relatively high, because it must be made of very expensive, pressure-resistant and load-bearing plastic, here with a good anti-friction plastic, and when adjusting, it is difficult for the assembler , the mutual rotation of each sleeve cannot be easily grasped.

As shown for example in DE 195 28 101 C1 and EP 0 832 526 A2, the basic principle of the rotatable sleeve has been further developed in many ways for storing hinge plate pins. However, structurally complex sleeves and correspondingly complex recesses are still required in the hinge plate part.

Among other things, another way of adjusting the sleeves perpendicular to the plane of the frame or the plane of the sash without turning the sleeves relative to each other is described in the "KOMPAKT 3D" door hinge plate from the company SCHTS-DUIS. Here, the hinge plate pin is seated with its upper pyramid-shaped longitudinally toothed part in the corresponding toothing of the pivot part of the hinge plate wing part, and its verticality is determined by a turned-up U-shaped part. At the position of the frame plane or fan plane, the size of the formed part changes according to the required opening size. The opening dimension is the distance from the front plane of the fixed frame to the front plane of the leaf, that is to say also the distance between the two planes on which the hinge plate part is fastened. This opening size can be different in different door, window and the like products. In order to compensate for this, each hinge plate is simultaneously supplied with a batch of several compensating parts, so that the processor can select the correct one from them. This arrangement of multiple small parts, from which the correct one must be selected, is an unreliable factor which will lead to defects. In addition, it is difficult to achieve an adjustment of the sealing pressure, which is often especially necessary for manufacturing-related differences in the opening dimensions.

The preamble of claim 1 is based on DE-GM 92 06 434, in which, in one of the hinge plate parts, if necessary in a hinge plate frame part, a rectangular recess is provided, the long sides of which are perpendicular to the frame Oriented in a plane or fan plane, in this rectangular recess sits a substantially square sleeve made of plastic which receives the hinge plate pin. Since the length of the rectangular recess is greater than the width, the sleeve and the hinge plate pin are allowed to move a certain distance along the direction of the longitudinal centerline of the rectangular recess. As a result, the hinge plate pin also moves the same distance against the hinge plate frame portion. In order to be able to position the hinge plate pin together with its sleeve in a definite position, a strip-shaped spacer structure can be preset. At this time, the strip is as wide as the rectangular recess and is aligned with the ends of the sleeve and the rectangular recess. The gap between them is as thick. The strip can also sometimes be moved to this side and sometimes to the other, whereby different adjustment possibilities can be obtained when the gasket structure is divided into two thinner strips which can become intermediate stages. Sex can also be finer.

Here, however, the hinge pins still have to be accommodated in high-quality, expensive and thus expensive hinge pin bushings.

The object of the invention is to simplify such hinged plates while maintaining the possibility of adjustment.

This object is achieved by the invention described in claim 1 .

This simplification is achieved by the fact that, first of all, when forming the relevant hinge plate part, the recess itself has a very simple, crack-free and problem-free cross-sectional shape that can be produced simultaneously without requiring special additional machining.

In this simple cross-sectional shape, the hinge plate pins engage directly, ie no special bushings or guides are present. The hinge plate pin is guided laterally bearing directly on the material of the hinge plate part. The gap in the direction of the longitudinal centerline, that is to say the distance due to which the length of the recess is greater than the width, will be filled by a spacer structure comprising at least one member which at least substantially fills the hinge At least one free space is left between the plate pin and the end wall. Overall, the adjustment according to the invention combines maximum structural simplicity with particularly easy handling, the arrangement of the shim structures directly reflecting the desired adjustment. The adjustment will not affect the adjustment of the other two spatial directions.

In a preferred embodiment of the invention, the hinge plate pin also has a circular cross-section on the side of the hinge plate part which allows the adjustment of the hinge plate pin. In this case, the side of the spacer structure facing the hinge plate pin and preferably also the end wall which receives the end wall of the hinge plate pin has a cross-sectional configuration adapted to the circular cross-section of the hinge plate pin.

When referring to "front", "rear", "upper" and "lower" herein, it is always from the perspective of an observer located in front of the hinge plate, referring to the mounting position when the pivot axis is vertical.

The design according to the invention can in principle be used for all adjustments in the horizontal plane, that is to say not only on the hinge plate frame part but also on the hinge plate wing part.

However, in a preferred embodiment according to claim 3 provision is made for the configuration according to the invention to be adjusted in the direction of the opening dimension and on the hinge flap part.

The strip-shaped washer structure can be moved tightly from above into the gap determined by the play in the recess. Therefore, the spacer structure requires a certain width to avoid longitudinal bending during the insertion process. According to claim 4, a width of 0.4-0.8 times the width of the recess has proven suitable.

When the spacer structure is an integral part, the hinge plate pins can only be secured in two positions. In order to expand the number of possible positions, it is proposed that the spacer structure according to claim 5 consist of at least two separate part-cylindrical separate shells.

According to claim 6, it is also advantageous if the individual shells have different thicknesses. According to claim 7, the individual shells can be detachably connected to each other so that they cannot be lost during transport, wherein, for example, according to claim 8, the individual shells can be pivoted to each other along adjacent longitudinal edges by means of a film hinge structure The hinge structure can be separated if necessary.

An important development of the invention is the object of claim 9 . The top guard closes the pivot section upwards and additionally transmits the necessary forces acting on it when moving into the spacer structure. In this case, the insertion can take place by exerting pressure or also by careful hammering.

The hinge plate pin can be fixed longitudinally in the pivot part in a known manner by a countersunk screw which engages with a corresponding circumferential recess of the hinge plate pin. As such, no other passage for the countersunk screw to reach the hinge plate pin is required, and it is recommended that the spacer structure or its separate housing have a hole where the countersunk screw passes.

An exemplary embodiment of the invention is shown in the drawing.

FIG. 1 shows a fixed frame 1 on which a leaf frame 2 can be swiveled about a vertical pivot axis S by means of two or three hinge plates 100 arranged above and below in a conventional manner.

The fixed frame 1 and the fan frame 2 are made of plastic hollow profiles, which are reinforced by deep-drawn metal profiles. The fixed frame 1 has a flat front side 1' which defines the frame plane. The fan frame 2 has a flat front side 2' which defines the plane of the fan. The flat front side 2' of the fan frame 2 is located in front of the front side 1' according to the so-called opening dimension 26, so that the fan frame 2 can pass over the front side 1' with a joint edge 2". There is a chamber 3 behind the joint edge 2" , for receiving a lip seal, not shown, seated against the front side 1'. On the back side of the plastic hollow profile of the fixed frame 1 there is a structure formed corresponding to the joint edge, in which a chamber 4 is formed for receiving the base of a not shown lip seal facing the back side of the fan frame 2 take a seat. A certain sealing pressure in the direction of the arrow K in FIG. 1 is required in the frame 1 for the tightness of the fan frame 2 .

The hinge plate 100 is composed of a hinge plate frame portion 10 and a hinge plate wing portion 20 . The hinged plate frame part 10 comprises a strip-shaped upright fastening part 11 which is engaged at its upper part through a fastening screw engaging on the flat front side 1 , which screw is not shown in FIGS. 13 and 14 . In the lower part, a cantilevered pivot portion 12 protrudes.

The hinged flap part 20 also includes a plate-shaped fixing part 21 longitudinally mounted on the flat front side 2' of the fan frame 2 in a manner not shown in detail, at its left end in FIG. Part 22 , the pivoting part is superimposed on the pivoting part 12 . In the overlapping region there is a hinge pin 5 which cannot be found in FIG. 1 and forms a vertical pivot axis S around which the hinge wing part 20 and thus the fan frame 2 can pivot relative to the hinge frame part 10 .

The fan frame 2 is required to be adjusted in the frame opening formed by the fixed frame 1 when it is embedded. For this purpose, the hinge plate 100 includes adjustment means for all three spatial directions. The means for adjusting in the direction of the arrow H, and in the horizontal plane parallel to the fan plane, are integral with the fixing part 21 of the hinged flap part 20 and will not be further described. The means for adjustment in the vertical direction V are integral with the pivot portion 12 of the hinge plate frame portion 10 . The lower end of the hinge plate pin 5 is seated in a hinge plate pin sleeve 6 which is arranged in a corresponding recess 7 of the pivot portion 12 and engages underneath with a screw 8 which can be pivoted Screw up and screw down in internal thread 9 of part 12. At this time, the hinge plate pin sleeve 6 is driven along the direction of V, and the fan frame 2 rises or falls as required.

Pivot part 22 of the device and hinge flap part 20 for adjustment in the direction of the third arrow A, i.e. perpendicular to the frame or fan plane determined by the front side 1' or 2' or in the direction of the opening dimension into one. The pivot part 22 has a recess 13 for receiving the upper part of the hinge plate pin 5, the cross-section of which is shown separately in FIG. 2 . The cross section of the recess 13 consists of two opposing semicircles 14 , 15 with the same radius r, which corresponds to the radius of the hinge plate pin 5 . The midpoints of the semicircles 14 , 15 are at a distance 18 from one another along a longitudinal center line 17 oriented parallel to the arrow A, which corresponds to the adjustment range. The semicircles 14 , 15 are connected to each other by straight sections 16 , 16 . This results in an oval shape through which the hinge plate pin 5 passes, so that the hinge plate pin is guided laterally, but can move parallel to itself along a straight line 18 in the direction of the longitudinal center line 17 .

The recess 13 in the pivot portion 22 is depicted in FIG. 3 . It can be seen that the hinge plate pin 5 has a clearance of 18 in the direction of the longitudinal center line 17, but this clearance is eliminated in the embodiment by a strip-shaped spacer structure 30, which can be parallel to the The pivot axis S moves tightly into the gap 19 between the hinge plate pin 5 and the lower end of the recess 13 of FIG. 3 . The spacer structure 30 is a part-cylindrical shell whose inner and outer radii correspond to the radius r of the recess 13 and the same radius of the hinge plate pin 3 in the area present in the recess 13, the width of which is approximately It is 0.4 to 0.8 times the diameter of the hinge plate pin 5 , in the exemplary embodiment shown it is approximately 0.6 times. As can be seen from FIG. 3 , the spacer structure 30 is arranged opposite to the mounting area of the hinge plate pin 5 in the upper semicircle, symmetrically to the longitudinal center line 17 .

In the described embodiment, it is characteristic that the spacer structure 30 itself consists of two separate shells 32, 33, wherein the outer shell 32 is almost twice as thick as the inner shell 33, however, the separate shells The sum of the thicknesses in this case corresponds to the quantity 18 in FIG. 2 . Dividing the spacer structure 30 into two separate shells 32 , 33 which bear against each other when superimposed allows simplifying the positioning of the hinge plate pin 5 in the pivot part 22 .

The individual shells 32, 33 can be connected at their longitudinal edges with a film hinge 34, so that they are connected to each other in the transport state and cannot be lost. The individual shells 32, 33 can be stacked on top of each other in the manner seen from FIGS. 5 and 6 due to the film hinge 34, so that, as also shown in FIG. side.

However, it is also possible to separate the individual shells 32 , 33 at the film hinge 34 and insert them on different sides of the hinge plate pin 5 as shown in FIGS. 7 and 8 .

As can be seen particularly from FIGS. 6 and 8 , at the upper end of the separate shell 32 there is provided a protective roof 35 protruding perpendicularly to the pivot axis S, whose shape is a profile matching the pivot portion 22 , at the corners. A rounded generally square plate. The separate shell 33 is not connected to the roof 35 so that it can be inserted on the opposite side as seen in FIG. Recesses 13 receive and distribute forces when in place. When the correct shape is chosen, the spacer structure 30 will be subjected to a force P from above in the gap 19 left in the recess 13 in the direction of the longitudinal centerline, either by finger pressure or by the force of a mallet. Hit lightly. Thereby, the spacer structure 30 is driven tightly into the gap.

Four degrees of adjustment, which can be achieved with the washer arrangement 30 of FIGS. 4 to 8 , are shown schematically in FIGS. 9 to 12 . At this point, they are only described in partially shifted-in states.

In FIG. 9, both the thicker separate shell 32 and the thinner separate shell 33 are arranged on the left so that the hinge plate pin 5 rests on the right side on the end of the recess 13, whereby, Positioned on the far right with respect to the pivot portion 22 .

In FIG. 10, the thinner separate shell 33 is separated from the thicker separate shell 32 corresponding to FIG. The thickness of the shell 33 is shifted to the left relative to the pivot portion 22 .

In Fig. 11, the top guard 35 has been turned through 180° so that the thicker separate shell 32 is now on the right, while the hinge plate pin 5 has moved its thickness to the left. The thinner separate shell 33 is now on the left.

In FIG. 12 , a thicker separate shell 32 is joined together again, but this time, contrary to FIG. 9 , to the right of the hinge plate pin 5 . This is a construction where the hinge plate pin is found on the far left.

Figures 13 and 14 show the structure of Figures 12 and 10 in more detail. The spacer structure 30 is the opposite of Figures 9 to 12, fully moved in. It can be seen that it extends substantially along the height of the pivot portion 22 . The top guard 35 closes the pivot portion 22 upwards, exactly following its contour. It improves the force action when driving into the shim structure 30 . Moreover, the spacer structure 30 also simultaneously serves to fix the roof guard 35 on the upper side of the pivot portion 22 . The connection of the top guard 35 to the spacer structure 30 prevents it from slipping in the circumferential direction according to FIG. 3 .

To secure the hinge pin 5 in the recess 13 in the axial direction of the hinge pin 5 , a countersunk screw 23 screwed in from behind is used which engages a circumferential recess 24 of the hinge pin 5 . In the case of Fig. 13, bonding can be performed directly. However, as in Fig. 14, for the case where at least one separate shell 32, 33 is arranged on the side of the countersunk screw 23, the separate shell 32, 33 has a hole 25 at the place of the countersunk screw 23, through which the countersunk screw 23 can pass. join.
