Description

The invention relates to a hinge for doors, windows or similar building elements, comprising at least one frame part fixed to the frame, at least one casement part fixed to the sash, a finger at least partially passing through the recesses of the frame and casement parts and forming the axis of the hinge, located at least in one of the recesses, an adjusting device with which the finger can move parallel to itself, an adjusting screw that runs parallel to the axis of the hinge, fixed in its direction and having an external thread, and a sleeve for accommodating a finger.

Such a loop is known from EP 860571 A1. The notch has on the front side, i.e. on the side facing away from the sash or frame, parallel to the hinge axis, a middle groove in which an elongated, parallel bounding guide element is located. Its cross section fits exactly to the groove, so that the guide element is installed in the groove without the possibility of displacement in the plane perpendicular to the axis of the hinge, but with the possibility of moving into the groove parallel to the axis of the hinge. The guide element has a flat back side, abutting against the flat front side of the sleeve of the finger with the possibility of movement. On opposite flat surfaces, an inclined guide is made, which ensures that when moving the guide element relative to the finger hub parallel to the axis of the hinge, which is caused by the adjusting screw forming the drive, the finger sleeve moves parallel to itself perpendicular to the axis of the hinge relative to the guide element.

True, with this hinge, the hinge axis can be moved relative to the hinge part fixing places and thereby the sash is aligned perpendicular to the hinge axis, also called horizontal adjustment, without the need to loosen the hinge part on the sash or frame, however, its drawback is that the adjustment device requires a lot of places, in particular, due to the guiding element, so that the hinge part, also called the loop head, which is located inside the adjusting device, is bulky, which negatively affects imparted looped appearance and limits its application. In addition, due to the large number of parts and machining required to make the guide surfaces of the loop head and the guide element, the loop is difficult to manufacture.

The basis of the invention is the task of creating a loop in which the movement of her finger parallel to itself relative to the places of fastening of the loop could occur without loosening the fastening, in other words, in which the adjustment would take place inside the loop head, which would be easier to manufacture and which would allow reduce the need for space for the adjusting device.

This problem is solved through a loop in accordance with paragraph 1 of the formula.

At this loop, the adjusting screw is installed in a slot made in at least one recess with a section in the form of a circular segment, which is oriented parallel to the axis of the hinge. Since the adjusting screw with its external thread is engaged with the corresponding internal thread made in the sleeve of the finger and having the shape of a circular segment in cross section, this adjustment screw performs two functions simultaneously, namely, on the one hand, the function of the guide sleeve of the finger parallel to the axis of the hinge, and , on the other hand, since it is fixed in the axial direction, is the function of moving the sleeve of the finger during its rotation. Thus, due to the threaded engagement, the finger sleeve is fixed in the direction of the hinge axis inside the recess, expanded in the direction of movement, in the form of an elongated hole, in the wall of which, opposite the adjustment screw, it abuts, however, due to the corresponding free angles provided between the sleeve and the socket in the area of the adjusting screw, the sleeve can move around its outer periphery.

In order for the sleeve to rotate not only in the direction of the hinge axis, but also across it, causing the finger placed therein to move parallel to itself, means are provided for guiding the sleeve in the recess, preferably having a protrusion directed in the wings. For this, the wings extend across the hinge axis.

It is particularly preferable to provide a protrusion on the sleeve, and the backstage in the recess, as this facilitates the manufacture of the loop. Thus, in a minimized version of the loop according to the invention, the link can be made, for example, due to the fact that the cut is cut out or milled from the outside in the loop head at an angle to the axis of the hinge.

In order to avoid, however, loosening of the loop head due to the wings and the risk of dirt penetrating through it into the loop heads, it is also possible to carry out the wings in the insert fixed in the recess.

In order to protect the loop finger in the aligned position also in the case of external dynamic loads from accidental movement, in one particularly preferred embodiment of the loop on the side opposite the adjusting screw there is provided at least one threaded hole extending into the recess in which there is a clamping screw securing when the finger is looped. This screw can be made in the form of a countersunk screw, preferably with a tapered end. The loop finger may have an annular groove suitable to the conical end, into which the countersunk screw enters in a screwed state with particularly effective protection against unauthorized removal. In addition, at least one countersunk screw may serve to secure the insert if present. Fixing the loop finger in the aligned position is particularly effective, in particular, because at least one clamping screw acts on the finger so that its sleeve presses the adjusting screw with its internal thread and presses it into the socket made in the loop head, as a result, threaded engagement between the adjusting screw and the sleeve and the geometric connection of the loop head, the adjusting screw and the sleeve are provided, at least with almost no clearance.

In one particularly preferred embodiment of the hinge, the adjusting screw is located on the side of the recess facing away from the sash or frame. Since at least one clamping screw located opposite the hinge finger is not accessible when the sash is closed, this hinge is used to achieve particularly high burglary protection without the need for special measures such as additional pads, fuses, etc.

In order to protect the adjusting screw in the direction of the hinge axis, it preferably has an annular groove into which a locking protrusion made on the loop head is included.

The locking protrusion can be molded on a loop in the recess. In the same way, it is possible to carry out the locking protrusion in the form of a separately mounted part in the recess. In the simplest case, it can be structurally implemented with a screw or rivet. To realize, however, the maximum planar entry of the locking protrusion into the annular groove, it is particularly preferred if the part is approximately half-ring in shape.

If an overlay is provided, as is desirable, for example, to close the fastening points of the hinge part on the sash or frame, and its external shape can be brought into line with the desired part of the hinge for aesthetic reasons, then a locking protrusion can also be made on the hinge head the inner side of the lining, and in the loop head there is a slot through which the part enters the recess and into the annular groove of the adjustment screw.

In the drawings, for illustrative purposes, various variants of the hinge portion of the hinge are shown. Of course, as an alternative, the frame parts of the loops can be made in the depicted or in any other known form.

In the first embodiment of the invention, in FIGS. 1-3, the hinge part 100, shown here as its sash part, comprises a plate 1 having a fastening part 2 with two holes 3 through which fastening screws (not shown) pass in the mounted state.

With the fastening part 2, the hinge part 4, also called the loop head, is molded in one piece. It has a recess 5, which serves to accommodate the adjusting device 6.

The adjusting device 6, by means of which the hinge pin 7 forming the hinge axis A can be moved parallel to itself along arrow P in Fig. 2, contains an adjusting screw 8 approximately in the form of a stud, on both end ends of which hex key depressions 10 are made (not shown) . In addition, approximately in the middle of the adjusting screw, an envelope ring groove 11 is formed, into which the locking protrusion enters as described below.

The adjusting device 6 also includes a sleeve 12 for the finger, essentially with a circular outer periphery. On this outer periphery, there is a corresponding circular thread, having the shape of a circular segment, extending at an angle of 45 ° to the outer periphery of the adjusting screw 9. On the opposite inner thread 13, the sleeve 12 has a flange 14, from which the protrusion oriented at an angle to the axis A of the hinge fifteen.

The recess 5 in the hinge part 4 is made in cross section approximately in the form of an elongated hole, as can be seen, in particular, in Fig.2. It has, in the width direction, the socket 16 shown in FIG. 2 at the top with a cross-section in the form of a circular segment that extends along an angle of about 90 ° and whose radius is aligned with the radius of the adjusting screw 8 so that it is installed in the socket 16, essentially no clearance.

The adjusting screw 8 is fixed in the axial direction by means of a part 17 of approximately semicircular shape, which passes through the slot 18 in the hinge part 4, is held in it in the axial direction and enters the annular groove 11.

As can be seen, in particular, in Fig. 3, the hinge part 4 has on its opposite socket 16 a side extending in accordance with the protrusion 15 at an angle to the axis A of the hinge, an additional slot 19, the parallel longitudinal sides of which form guide surfaces for the protrusion 15, and thereby backstage 20.

As can be seen, in particular, in figure 2, the recess 5 in the hinge part 4 has a surface 21 on the opposite side of the socket 16, the radius of curvature R of which approximately corresponds to the distance between the longitudinal middle axis S of the adjusting screw 8 and surface 21. The distance between the flat 14 of the sleeve 12 and the internal thread 13 is designed so that the sleeve 12 is held between the surface 21 and the adjusting screw 8, essentially without a gap.

When the adjusting screw 8 is rotated due to the fact that it is fixed in the longitudinal direction by part 17, the sleeve 12, due to threaded engagement, moves in the recess 5 first up and down, i.e. figure 2, depending on the direction of rotation of the adjusting screw 8 to the observer or from him. Due to the fact that the protrusion 15 entered the wings 20, the sleeve 12 simultaneously moves approximately around the longitudinal middle axis S or approximately along the surface 21, as indicated by arrow P in figure 2. To fix the finger 7 of the loop in the desired aligned position, two countersunk screws 22, which are screwed into the threaded holes 23, extending into the recess 5 of the hinge part 4. Each of them has a conical end section 24, the cone angle of which corresponds to two annular grooves 25 made in the finger 7 at a distance corresponding to the distance between the two countersunk screws 22.

In areas where the countersunk screws 22 act on the finger 7, the sleeve 12 has cutouts 26, designed so that it can move freely across the entire control range.

As can be seen, in particular, from figure 2, the countersunk screws 22 act on the finger 7 in the upward direction, so that when they are tightened, it presses on the adjusting screw 8, which presses into the socket 16, as a result of which the sleeve 12 is guided at least almost without a gap, and the external thread of the adjusting screw 8 is in reliable engagement with the internal thread 13.

With the help of FIGS. 4-6, corresponding to FIGS. 1-3, another embodiment of the invention is explained. Corresponding details or features are indicated in FIGS. 4-6 by the same reference numbers as in FIGS. 1-3, but with an increase of 100. Only differences are described to avoid repetition.

The function of this loop essentially corresponds to the function of the loop described above. First of all, however, its finger 107 is made longer, so that it is suitable for a three-part hinge, in which the casement part 200 is placed between two frame parts (not shown).

Another difference between the sash part 200, which can also be used if it, as described above, is used in a two-part loop, is that the link 120 is not made in the form of a slot directly in the material of the hinge part 4, but in an additional insert 127, which is located in its corresponding external contour of the recess 128 in the recess 105.

True, due to the insert 127, the number of parts necessary for the implementation of the sash portion 200 of the hinge increases, however, it is preferable that the insert 19 becomes unnecessary due to the insert 127, which makes it particularly difficult for dirt to penetrate into the hinge portion.

For fixing the insert 127, countersunk screws 122 are used, passing for this through the holes 129 in it. Otherwise, the sash part 200 corresponds to the sash part 100, however, however, the protrusion 115 on the sleeve 112 and the flange 114 correspond to the position of the wings 120 and the surface 121.

In the third embodiment of FIGS. 7-10, the hinge portion of the hinge is indicated by 300, and the corresponding parts or features are indicated by the same reference numbers as in FIGS. 1-3, but with an increase of 200. Also described here only differences.

The hinge portion 300 of the hinge further comprises an overlay 230 having, on the end 231 from the side of the fastening part 202, a protrusion 232, which is included in the undercut surface 233 made on the fastening part 202.

The trim 230 has a portion 234 with a cross section approximately in the form of a part of the ring, which covers the hinge part 204 from the outside at an angle of about 200 °.

As can be seen, in particular, in FIGS. 9 and 10, a part 217 is molded on the inner side of the portion 234, which secures the adjustment screw 208 in the longitudinal direction when putting on the pad 230.

To fix the plate 230 in its put on state (Fig. 8), a fixing screw 235 is provided, which is screwed in the transition zone between the fixing 202 and the hinge 204 parts from the rear side of the plate 201 into the blind threaded hole 236 of the plate 230.

In the fourth embodiment shown in FIGS. 11-15, the details or features of the hinge portion 400 are also indicated by the same reference numbers as in FIGS. 1-3, but with an increase of 300. Unlike the flap portion 100, the adjusting screw 308 is on the back side of the hinge portion 304 related to the sash, for which the socket 316, in comparison with the sash part 100, is made on the opposite side of the recess 305. Accordingly, the link 320 is made on the front side of the hinge part 304.

The protrusion 315, which enters into the wings 320 and is visible from the front, has a scale 337 on its front side. Together with the risk 338 made on the front side of the hinge part 304, the current adjusted position of the finger sleeve 312 and thereby of the finger 307 and the adjustment course carried out during adjustment can be seen.

The finger 307 is fixed in the direction of the hinge axis A by means of a fixing screw 340 screwed from the back into the hole 339, which enters the annular groove 325 of the finger 307. For this, the internal thread 313 of the sleeve 312 is interrupted by a recess 341 in the form of an elongated hole.
