Description

Hinges for doors, windows and the like

Technical field

The invention relates to a hinge for doors, windows and the like of a kind corresponding to the preamble of claim 1.

BACKGROUND OF THE INVENTION

Hinges for doors, windows and the like, consisting of aluminum or plastic, usually comprise a base body of extruded aluminum profile or zinc die-cast. The hinges are partly conditioned by the production of mutually parallel upper and lower sides, which in the installation position lie horizontally opposite each other. As a rule, the wings need to be adjusted in the frame opening after installation, namely in the horizontal direction, in the vertical direction and in the direction perpendicular to the frame surface, respectively. to the wing surfaces, when the wing is closed to the parallel. The frequency of embodiments is known for these adjustments. to the wing surface, designs have been used to change the position of the hinge pin relative to one of the pivotal parts. The earliest embodiments of this kind were eccentric bushes, respectively. however, these double eccentric bushings are quite expensive, since they have to consist of high-quality, pressure-resistant and load-bearing plastic materials, and also during adjustment do not result in the rotation of the separate bushings against well arranged for the installer.

The basic principle of the rotary bushings for receiving the hinge pin has been improved in many ways, as disclosed, for example, in DE 195 28 101 C1 and EP 0 832 526 A2. However, there are also required expensive housings and correspondingly complicated recesses in the hinge parts.

Another method is to adjust the perpendicularly to the frame surface or to adjust it. The wing surface, which the sleeves do not turn against each other, is realized at the door hinge „KOMPAKT 3D“ of the company SCHUT-DUIS. In this case, the hinge pin sits with its upper pyramidal longitudinally toothed part in the respective toothing of the hinge part of the hinge part of the hinge and is in its position perpendicular to the frame surface or the frame. wing surface, determined by a bent U-shaped fitting, whose dimensions vary according to the desired uncovered dimension. The uncovered dimension is the distance from the front face of the fixed frame to the front face of the wing, ie.

the distance between the two flat surfaces on which the hinge parts are fastened. This uncovered dimension may vary for different door, window and similar fabrications. In order to compensate for this, each hinge is supplied with a plurality of compensating parts, of which the processor uses the right one. This assignment of a larger number of small parts from which one must be selected is the unreliability factor leading to errors. In addition, adjustments to the sealing thrust, which in addition to the production-related differences in the exposed dimension, are often still required, are difficult to carry out.

The preamble of claim 1 is based on DE GM 92 06 434, in which a rectangular recess is provided in one part of the hinge or in the frame part of the hinge. wings. In this rectangular recess, there is a substantially square plastic housing which engages the hinge pin. Since the rectangular recess is longer than wider, the hinge pin sleeve may move a certain distance in the direction of the longitudinal median plane of the rectangular recess. This also relocates the hinge pin relative to the frame part of the hinge. Now that the hinge pin with its sleeve can be positioned at a certain location, a strip-like embodiment of the insert is provided, the strip being as wide as a rectangular recess and strong as the remaining clearance between the sleeve and the end of the rectangular recess. Thus, the strip can be moved one side to the other and the other side to the other, giving different adjustment options, which can be further refined when the overall thickness of the insert is divided into two thinner stripes that allow the intermediate stage.

- 1 GB 298920 B6

Here again, however, the hinge pin is located in the high-quality and correspondingly expensive hinge pin housing.

SUMMARY OF THE INVENTION

The object of the invention is to simplify the hinge according to the introduction while maintaining the possibility of adjustment. This object is achieved by the invention as set forth in claim 1.

The simplification is realized by the fact that the recess in particular has a completely simple, unbreakable cross-sectional shape which can be realized without difficulty in shaping the hinge part without any additional work.

In this simple cross-sectional shape, the hinge pin is immediately inserted. without the need for separate bushings or guide parts. Thus, the hinge pin is guided in the lateral direction under the immediate support on the material of the hinge part. Clearance in the direction of the longitudinal median plane; the distance by which the recess is longer than wider is bridged by an insert comprising at least one component, at least substantially filling at least one free space remaining between the hinge pin and the end wall. Overall, the adjustment according to the invention combines maximum construction simplicity with extremely obvious handling, in that the insert design immediately shows the desired adjustment. The adjustment takes place without affecting the settings in both other spatial directions.

In a preferred embodiment of the invention, the hinge pin is also circular in cross-section on the sides of the hinge pin adjustment part. In this case, the side of the insert facing the hinge pin and - preferably - also the end wall of the hinge pin receiving end wall has a cross-sectional shape adapted to the circular cross-sectional shape of the hinge pin.

When the terms "front", "rear", "top" and "bottom" are used, this always means the built-in position along the vertical axis of the mast as viewed by the observer having the hinge in front of him.

The forming according to the invention can in principle be applied to all adjustments in the horizontal plane, both on the frame part of the hinge and on the wing part of the hinge.

However, in a preferred embodiment according to claim 3, the shaping according to the invention is adapted to be adjusted in the direction of the exposed dimension and on the wing portion of the hinge.

The strip insert should be slid directly from above into the gap, due to the clearance in the recess. Therefore, a certain width of the insert is required to prevent buckling during the insertion process. According to claim 4, a width of 0.4 to 0.8 times the width of the recesses has proven useful.

If the insert was a one-piece part, the hinge pin could only be fixed in two positions. In order to increase the number of possible positions, it is recommended that the liner consists of at least two separate, partially cylindrical, separate shells according to claim 5.

According to claim 6 it may also be advantageous if the thickness of the separate shells is different. According to claim 7, the separate shells can be releasably connected to each other so as not to be lost during transport, eg the single shells of claim 8 are pivotably connected to each other along adjacent longitudinal edges by a foil mast which can be separated if necessary.

An important embodiment of the invention is the object of claim 9. The cover closes the hinge part upwards and, in addition, transmits the necessary forces to it when the insert is inserted. The insertion can be effected by the pressure exerted by the hand or by careful hammer impacts.

-2GB 298920 B6

The hinge pin can be fixed in the longitudinal direction in a known manner in the longitudinal direction by means of a fixing screw which engages a corresponding circumferential recess of the hinge pin. In order for the fixation screw to find access to the hinge pin without further delay, it is recommended that the insert and / or the hinge bolt should be removed. its separate shells, had a hole at the point where the fixation screw passed.

DETAILED DESCRIPTION OF THE INVENTION

Referring to Fig. 1, a fixed frame 1 is shown, in which the wing frame 2 is pivoted in a conventional manner by two or three hinges 100 arranged one above the other about the vertical axis S.

The fixed frame 1 and the sash frame 2 consist of plastic hollow profiles, which are reinforced with reference metal profiles. The fixed frame i has a straight front side určuje which determines the frame area.

The wing frame 2 has a straight front side 22 which defines the wing surface. The straight front 2 / sash 2 lies in the so-called uncovered dimension 26 in front of the front V so that the sash 2 with the groove 22 may extend beyond the front i. On the back of the groove 22 there is a chamber 3 to receive a lip seal not shown. On the rear side, the plastic hollow profile of the fixed frame 1 has a corresponding groove forming a forming in which it forms a chamber 4 for engaging the foot of the lip seal not shown, which settles against the rear side of the wing frame 2. a certain sealing pressure is required within the meaning of arrow K in FIG. 1.

The hinge 100 comprises a hinge frame part 10 and a hinge wing part 20. The hinge frame portion 10 includes a tape-like, flat fastening portion 11 that is pierced in its upper portion by fastening screws that engage a straight front portion Γ, not shown in Figures 13 and 14. A cantilevered mast part 12 projects from its lower part.

Also, the hinge wing portion 20 includes a longitudinal plate-like fastening portion 21, not shown in a not shown manner on the straight front side 2 / of the wing frame 2, in which, in FIG.

In the overhang region, there is a hinge pin 5, which is not visible in FIG. 1, forms the vertical axis S of the hinge and the hinge part 20 of the hinge, and thus the sash frame 2 is around it pivots relative to the frame part 10 of the hinge.

The wing frame 2 requires, in a flush mounting, a setting in the frame opening formed by the fixed frame 1. For this purpose, the hinge 100 includes adjustment possibilities for all three spatial directions. The adjustment device in the sense of the arrow H, that is to say horizontally parallel to the plane of the wing, is integrated into the fastening part 21 of the wing part 20 of the hinge and is not further illustrated. The vertical displacement device V is integrated into the hinge part 12 of the hinge part 10, the lower end of the hinge pin 5 being seated in the hinge pin housing 6, which is provided in a corresponding recess 7 of the hinge part 12 and supported by the threaded portion 8 which screwable In this case, the hinge pin housing 6 is carried in the V direction and the sash frame 2 is raised or lowered as required.

A device for adjusting in the direction of the third arrow A, i. perpendicular to the frame surfaces; the wing surfaces determined by the front sides V and / or. 2S resp. in the direction of the exposed dimension, it is integrated into the hinge part 22 of the hinge part 20. The hinge part 22 has a recess 13 for receiving the upper part of the hinge pin 5, the cross section of which is shown separately in FIG. 2. The cross-section of the recess 13 consists of two opposite semicircles 14, 15 with the same radius r which coincides with the radius of the hinge.

5 hinge. The centers of the semicircles 14, mají5 have a distance 18 corresponding to the adjustable region along the longitudinal median plane 17, which is aligned parallel to the arrow A. The semicircles 14, 15 are connected to each other by straight portions 16, 16. Thus, an oval shape is provided in which the hinge pin 5 fits laterally, but can be displaced in the direction of the longitudinal center plane 17 by a distance 18 parallel to itself.

Fig. 3 shows a recess 13 inside the hinge part 22. It can be seen that the hinge pin 5 has a clearance of 18 in the direction of the longitudinal median plane 17, but in the exemplary embodiment is balanced by a tape insert 30 which is parallel to the S axis. 3, the lower end of the recess 13 in FIG. 3. The insert 30 is a partially cylindrical shell whose inner and outer radii correspond to the radii r of the recess 13, respectively. the same radius of the hinge pin 5 in the area available in the recess 13 and whose width 31 corresponds to about 0.4 to 0.8 times, in the illustrated embodiment approximately 0.6 times the diameter of the hinge pin 5. The insert 30, as seen in FIG. 3, is arranged opposite the bearing region of the hinge pin 5 on the upper semicircle symmetrically to the longitudinal median plane 17.

In the illustrated embodiment, it is a peculiarity that the liner 30 consists of two separate shells 32, 33 on its side, of which the outer 32 is approximately twice as thick as the inner 33, but the sum of the thickness of the single shells corresponds to 18 in FIG. The liners 30 into two separate shells 32, 33, which are flush with each other, allow refinement of the positioning of the hinge pin 5 in the hinge portion 22.

The individual shells 32, 33 may be joined at one longitudinal edge by means of the foil mast 34 so that they hang on each other in the transport state and do not lose. The separate shells 32, 33 can be tilted by the foil hinge 34 in the manner shown in Figs. 5 and 6 so that the overall thickness of the insert lies on one side of the recess 13, as also indicated in Fig. 3.

However, the separate shells 32, 33 can also be separated at the foil hinge 34 and inserted on different sides of the hinge pin 5, as indicated in Figs. 7 and 8.

6 and 8, at the upper end of the separate shell 32 there is a substantially oblong cover 35 in the shape of an approximately square, rounded plate at the corners, adapted to the shape of the plan view of the hinge portion 22. The separate shell 33 has a thickened portion 36 at its upper end to absorb and distribute the forces when the insert 30 is inserted into the recesses.

13. When the correct configuration is selected, a force P is applied to the insert 30 from the top of the joint 19 remaining in the longitudinal median plane 13, either by finger pressure or by a slight hammer impact. Thereby the insert 33 is directly driven into the joint 19.

Figures 9 to 12 show schematically the four adjustment stages which can be achieved by the insert 30 according to Figures 4 to 8, which are indicated only in a partially retracted state.

In FIG. 9, both the thicker single shell 32 and the thinner single shell 33 are provided on the left side, so that the hinge pin 5 abuts on the right side at the end of the recess 13 and is thus positioned maximally to the right of the hinge portion 22.

In Fig. 10, the thinner single shell 33 of Fig. 7 is separated from the thicker single shell 33 and provided on the right side of the hinge pin 5, so that the thinner single shell 33 of Fig. 10 is displaced to the left of the flag portion 22.

In Fig. 11, the cover 35 is rotated 180 ° so that the thicker single shell 32 now stands to the right and the hinge pin 5 is displaced to the left by its thickness. The thinner single shell 33 is now located on the left side.

In FIG. 12, it is again connected to a thicker single shell 32, this time in contrast to FIG. 9 on the right side of the hinge pin 5. This is therefore the configuration in which the bolt is located furthest to the left.

Giant. 13 and 14 show the configuration of FIG. 10, in a somewhat more detailed view. The inserts 30, in contrast to FIGS. 9 to 12, are fully inserted. It can be seen that they extend substantially over the height of the hinge portion 22. The covers 35 enclose the hinge portion 22 upwards corresponding to the plan view. At the same time, the insert 30 serves to secure the cover 35 on the upper side of the staple portion 22. The connection of the cover 35 with the insert 30 also prevents them from slipping in the circumferential direction.

The fastening bolt 23, which engages in the peripheral recess 24 of the hinge pin 5, serves to fasten the hinge pin 5 in the direction of its axis in the recess 13. In the case of FIG. 13, the engagement may take place directly. In the event that at least one discrete shell 32, 33 is provided on the side of the fixing screw 23, as in FIG. 14, the discrete shells 32, 33 have an opening 25 in place of the fixing screw 23 through which the fixing screw 23 can penetrate.
