Description

The invention relates to a structural (assembly) assembly (group) of a hinge for pivotally movable around the hinge axis for attaching a sash to a frame, with a mounting part that can be mounted on the mounting side of the sash or frame, with a hinge wing that can be mounted on the mounting parts, and the mounting part has an undercut groove with a groove opening and with a longitudinal axis of the groove, which runs parallel to the hinge axis, and the hinge wing has a groove nut that enters the undercut groove of the mounting part, and with the first adjusting means, with which the hinge wing has the possibility of rotation around the rotary axis relative to the mounting part by an adjusting angle in the first adjusting area.

The invention also relates to a hinge with such a structural unit.

A hinge with a similar design is known from EP 2 725 174 A1. Since the hinge wing can be rotated about the pivot axis relative to the mounting part by an adjustment angle, the adjustment of the sash in the frame in a direction perpendicular to the hinge axis - also referred to as horizontal adjustment - is possible in a simple manner by actuating the first adjustment means.

From DE 10 2015 214 168 B3 a hinge with a hinge wing is known, in which the wing of the adjusting hinge is rotatably mounted in the groove of the mounting part and is displaceable relative to the mounting part by means of a gear. At the same time, said transmission includes a kinematic connection between a toothed rod located on the hinge wing and a gear wheel located on the mounting part, so that continuous rearrangement is possible.

From DE 201 05 413 U1, a hinge is known with a hinge wing hinged on the mounting part. To absorb the vertical load from the sash with a slight deformation of the hinge, the retaining rib can be supported on the protrusion of the mounting part. Adjustment of the hinge wing relative to the mounting part is only possible with a free gap between said holding rib and said ledge.

Finally, publications EP 3 266 970 A1 and EP 2 725 174 A1 show door hinges.

However, in practice, it turned out that a hinge having such a constructive assembly requires improvement in terms of its ability to be used in the case of heavy sashes.

Therefore, the invention is based on the task of creating an improved, respectively, this structural (assembly) unit named at the beginning of the genus and including this structural unit of the loop.

This problem is solved by means of the structural unit described in paragraph 1 of the formula and by means of the hinge formula described in paragraph 9.

With the assembly according to the invention, one of the mounting part and the hinge wing includes a guide recess, which is located at a distance from the undercut groove in a direction perpendicular to the longitudinal axis of the groove. The guide recess has a recess length parallel to the longitudinal axis of the groove and a recess depth perpendicular to the longitudinal axis of the groove. The recess depth is limited by two side walls. The other of the mounting part and the wing of the hinge includes a guide ledge included in the guide recess, which engages with the guide recess in the adjustment area. The guide protrusion has a protrusion length and a protrusion height. The height of the protrusion is limited by two side surfaces.

With the assembly according to the invention, the guide projection and the guide recess provide a measure by which additional restraint forces from the hinge wing can be introduced into the mounting part without the adjustment being hindered or adversely affected as a result.

The wording "one of the mounting part and hinge wing" means that the measure to which this wording refers can be provided either on the mounting part or on the hinge wing. Accordingly, the wording "another of the mounting part and the hinge wing" should demonstrate that the measure to which the last wording refers is in this case respectively implemented on another structural part, i.e. either on the hinge wing or on the mounting part.

Preferably, the guide recess is made in such a way that its length extends along the entire length of one of the mounting part and the wing of the hinge. Accordingly, the guide protrusion is preferably designed in such a way that its length extends along the entire length of the other of the mounting part and the hinge wing. These measures aim to maximize the surfaces on which the guide protrusion and the guide recess abut each other in order to reduce the specific loads in relation to the highest possible load capacity of the structural unit according to the invention.

Against this background, according to the invention, it is provided that the side walls of the guide recess in the direction of the depth of the recess each have a bend with a bending radius, which respectively corresponds approximately to the distance from the corresponding side wall to the pivot axis. Furthermore, according to the invention, the lateral surfaces of the guide lip have a bend in the direction of the height of the ridge, which approximately corresponds to the distance from the respective lateral surface to the pivot axis. As a result, it can be ensured that a clampless adjustment is guaranteed even when the component according to the invention is heavily loaded. If, as is particularly preferred, the depth of the recess and the height of the rib are designed in such a way that the guide rib engages with the guide recess in the entire adjustment area, then as a result of these measures, clampless (without wedging) displacement can be ensured while at the same time the possibility of a high ultimate load according to the invention structural unit in the entire adjustment area.

In a preferred embodiment of the assembly according to the invention, the mounting part has at least one opening for the fastening means in the region of the pivot axis. Thus, in this embodiment, a fastening means, for example a fastening screw, can be provided, with which the holding forces for the mounting part in the area of the pivot axis are introduced into the frame or the sash. Since, as already explained above, the holding forces are transferred from the hinge wing to the mounting part by means of the interactions of the slot block and the undercut slot, i.e. in the area of the pivot pin, they can now be inserted into the sash or frame as a result of these measures, without the action (effect) of a very large lever, as could be the case, for example, when there are very large distances between the opening and the pivot pin. This can be an advantage to increase the ultimate (permissible) load of the structural unit.

Furthermore, it is particularly advantageous to provide a recess on the hinge wing through which said at least one fastening means can be inserted into the opening and actuated. In such a case, mounting the assembly according to the invention on the hinge or on the frame is possible even if the hinge wing is pre-mounted on the mounting part, which can facilitate handling of the assembly according to the invention.

In a preferred embodiment of the assembly according to the invention, the first adjusting means includes a pressure screw, which is provided in the first threaded hole of the hinge wing spaced from the pivot axis and rests on the mounting part. Thus, actuation in the sense of screwing the pressure screw into the threaded hole results in the pivoting of the hinge wing around the pivot axis in the sense of increasing the adjusting angle. In this embodiment of the assembly according to the invention, the first adjusting means also includes a clamping screw, which includes a head with a bearing surface. This tightening screw is preferably provided in a second threaded hole of the mounting part spaced from the pivot axis and penetrates the hinge wing in an opening preferably in the form of an elongated hole parallel to the longitudinal axis of the groove. Since the head rests with its bearing surface on the hinge wing, actuating the tightening screw in the sense of screwing in leads to the rotation of the hinge wing in the sense of reducing the adjusting angle. By locking the pressure screw and the locking screw, the hinge wing can be prevented from turning relative to the mounting part and thus the sash can be locked in relation to the frame in the horizontal adjustment position reached.

In another preferred embodiment of the component according to the invention, a second adjusting means is provided, with which the hinge wing can be displaced relative to the mounting part in the direction of the longitudinal axis of the groove. By means of this measure, with the aid of the component according to the invention, it is also possible to adjust in the direction of the hinge axis - also referred to as vertical adjustment.

In addition, the second adjusting means may have a support screw, which is screwed at one end into the thread of the undercut groove and on which the slot block rests. Vertical adjustment is possible by turning the support screw. In order to be able to fix the hinge wing relative to the mounting part in the achieved vertical adjustment position, a locking screw is provided, which is screwed into the thread of the undercut groove from the other end and presses the slot crack against the support screw. In practice, the lock screw is tightened when the desired vertical adjustment position has been reached with the support screw.

The invention also relates to a hinge for a sash-to-frame connection that can be pivotally movable around a hinge axis with a structural unit according to the invention.

Designated in the drawings as a whole with the position "100", an embodiment of the hinge according to the invention (hereinafter briefly hinge 100) includes a sash hinge part 1 and a frame hinge part 2. The hinge 100 serves for the hinge-movable connection of the sash not shown in the drawings around the hinge axis S with frame not shown.

As can be seen, in particular, in figures 2 and 3, the hinge 100 frame hinge part 2 is made of two parts: it includes - with respect to the location in which the hinge axis runs almost vertically - the lower hinge part 3 and the upper hinge part 4. Each of the lower and upper hinge parts 3, 4 includes a fastening part 5, 6, which is integrally connected to the hinged part 7, 8. The fastening parts 5, 6 serve to fix the lower and upper hinge parts 3, 4 on the fastening surface not shown in the frame drawings. To this end, an upper and lower clamping part 9, 10 is provided, by means of which, by screwing the clamping screws 11 into the threaded holes 12 of the clamping parts 9, 10, a force-locking connection to the not shown frame is achieved. Other fixing screws 13 are also provided, which are screwed into the frame, for positive locking. To this end, the fastening screws 13 are designed as self-drilling or self-tapping screws.

Hinge parts 7, 8 each include a hole 14, which serve to receive the hinge pin 15 defining the hinge axis S.

The sash hinge part 1 includes a structural unit 16. This, in turn, includes a mounting part 17, which can be mounted on the mounting side of the sash, which is not shown in the drawings.

Further, the structural unit 16 includes a hinge wing 18, which is adapted to be fixed on the mounting part 17. Further, an undercut groove 19 is provided with a groove opening 20 and with a longitudinal axis A of the groove, which runs parallel to the hinge axis S, which is at the hinge 100 located on the mounting part 17 (see, in particular, Fig.7). In accordance with this, the wing 18 of the hinge includes a slot cracker 21, which is included in the undercut groove 19 of the mounting part 17.

On the wing 18 of the hinge, a hinge part 29 is molded, which has an opening 22 through which the hinge pin 15 passes when the sash hinge part 1 is connected to the frame hinge part 2.

In the hinge 100, the mounting part 17 includes a guide recess 23 which is located at a distance from the undercut groove 19 in a direction perpendicular to the longitudinal axis A of the groove. The guide recess 23 has a recess length I which extends along the entire length G of the mounting part 17.

Further, the guide recess 23 has a recess depth t perpendicular to the longitudinal axis A of the groove, which is delimited by two side walls 24, 25 (see in particular FIG. 7).

The wing 18 of the hinge includes a guide protrusion 26 included in the guide recess 23. It has a length v of the protrusion, which corresponds to the entire length of the wing 18 of the hinge. The height h of the protrusion is limited by two side surfaces 27, 28.

As can be seen in particular in FIG. 5, the side walls 24, 25 of the guide recess 23 are curved with a radius r, r' of curvature, which (bend) corresponds approximately to the distance of the respective side walls 24, 25 from the pivot axis B, around which the wing 18 of the hinge can be rotated in the undercut groove 19. In the shown structural unit 16, the pivot axis B and the longitudinal axis A of the groove are superimposed on each other.

Also, the side surfaces 27, 28 of the guide 26 respectively have a curvature that corresponds approximately to the distance r, r' of the respective side surface to the pivot axis B, so that the side surface 27 bears at least almost flat against the side wall 24 and the side surface 28 - to the side wall 25.

The opening 20 of the groove is fitted to the contour of the groove cracker 21 in such a way that the hinge wing can be rotated around the rotary axis B by an adjustment angle α. 4 shows the maximum adjustment angle, the minimum adjustment angle α is 0°. The depth t of the recess and the height h of the protrusion are set in such a way that the guide protrusion 26 is engaged with the guide recess 23 over the entire adjustment area J - where 0°≤J≤α takes place,

Structural unit 16 includes a first adjusting means 30, with which the hinge wing 18 can be rotated around the rotary axis B relative to the mounting part 17 by an adjusting angle α in the adjusting area J. For this, there is a pressure screw 31, which is provided in the first distanced from rotary axis In the threaded hole 32 of the wing 18 hinges and rests on the mounting part 17 (see, in particular, Fig.5 and 7).

Further, the first adjusting means includes a pinch screw 33, which has a head 34 with a bearing surface 35. The pinch screw is screwed into the second threaded hole 36 of the mounting part 17 spaced from the rotary axis B. It penetrates the wing 18 of the hinge in the opening 37, and its head 34 rests with its bearing surface 35 on the wing 18 of the hinge. The opening 37 is made in the form of an elongated hole in the direction parallel to the hinge axis S.

Furthermore, the structural unit 16 includes a second adjusting means 38, with which the hinge wing 18 is able to shift in the direction of the longitudinal axis A of the groove relative to the mounting part 17. For this, the second adjusting means 39 includes a support screw 39, which at one end screwed into the thread 40 of the undercut groove 19 and on which the slot block 21 rests. Further, the second adjusting means 38 has a locking screw 41, which is screwed into the thread 42 of the undercut groove 19 from the other end and presses the slot block 21 against the support screw 39.

To reduce friction between the hinge part 29 of the sash hinge part 1 and the hinge parts 7, 8 of the frame hinge part 2, as well as the hinge pin 15, sliding bushings 43 are inserted into the hole 22 of the hinge part 29, which can be made, for example, from a polymer material.

To fasten the sash hinge part 17 to the sash, which is not shown in the drawings, a clamping part 44 is used in turn, the clamping action of which is carried out by means of clamping screws 45, which are screwed into the threaded holes 47 of the clamping part 44 through the holes 45 of the mounting part 17. Moreover, fixing screws 48 are provided, which are screwed into the sash. These, in turn, are provided in the form of self-tapping or self-drilling screws. The fixing screws 49 are provided in the region of the rotary axis B. In order to be able to insert the fixing screws 49 into the holes 50 of the mounting part 17 provided for them, the wing 18 of the hinge has a recess 51. The groove nut 21 is divided into two parts due to the recess 51. The fastening of the hinge wing 18 on the mounting part 17 is carried out using mounting screws 52, which are screwed into the threaded holes 54 of the mounting part through the openings 53 of the hinge wing 18, made in the form of oblong holes in the direction parallel to the hinge axis S. To align the hinge wing 18 relative to the mounting part 17 in the horizontal or vertical direction, the mounting screws are loosened and, after the adjustment position has been reached, they are firmly tightened again in order to fix the hinge wing 18 again.

With the hinge 100, a structural unit 16 according to the invention is provided on the sides of the sash hinge part 1. Of course, instead of this or additionally, the frame hinge part 2 can be provided with a structural unit 16 according to the invention.
