Description

Assembly of a hinge for hinge-jointed connection of a wing to a frame and hinge with this

module

The invention relates to an assembly of a hinge for hinge-jointed connection of a wing to a frame, with a mounting part which can be mounted on a mounting side of the wing or the frame, with a hinge tab which can be fastened to the mounting part, wherein one of the assembly part and the hinge tab has an undercut groove with a slot opening and with a longitudinal axis that extends parallel to the hinge axis, and the other of the assembly part and the hinge tab has a slot nut that engages in the undercut groove of the assembly part, and with a first adjustment means with which the hinge plate can be pivoted about a pivot axis relative to the mounting part by an adjustment angle in a first adjustment range.

The invention also relates to a belt with such an assembly. A band with such an assembly is known from EP 2 725 174 Al. Since the hinge plate can be pivoted about the adjustment angle about the pivot axis relative to the mounting part, an adjustment of the wing in the frame in the direction perpendicular to the hinge axis - also called horizontal adjustment - is possible by actuating the first adjusting means in a simple manner. In practice, however, it has been shown that a hinge having this assembly can be improved with regard to its usability in the case of heavy sashes.

The invention is therefore based on the object of creating an improved assembly of the type mentioned at the outset and a belt comprising this assembly.

This object is achieved by the assembly shown in claim 1 and by the tape shown in claim 11.

In the assembly according to the invention, one of the assembly part and the hinge tab comprises a guide recess which is arranged at a distance from the groove in the 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 depth of the recess is limited by two side walls. The other of the mounting part and the band tab comprises a guide projection which engages in the guide recess and which engages with the guide recess in the adjustment region. The guide protrusion has a protrusion length and a protrusion height. The projection height is limited by two side surfaces.

In the assembly according to the invention, a measure is created with the guide projection and the guide recess, by means of which additional holding forces can be introduced from the hinge flap into the mounting part without the adjustability being made difficult or impaired thereby.

By the wording “one of the assembly part and the hinge flap” it is meant that the measures to which this wording relates can be provided either on the assembly part or on the hinge flap. Accordingly, the wording “the other of the assembly part and of the hinge tab "to express that the measure to which the last formulation relates is then in each case on the other component, ie either on the hinge tab or on the assembly part. The guide recess is preferably designed in such a way that its recess length extends over the entire extent of the one of the mounting part and the hinge tab. Accordingly, the guide projection is preferably designed in such a way that its projection length extends over the total extent of the other of the mounting part and the band tab. These measures serve the endeavor to enlarge the surfaces on which the guide projection and the guide recess lie against one another as much as possible in order to reduce the surface loads with a view to the highest possible load capacity of the assembly according to the invention.

Against this background, an embodiment is further preferred in which the side walls of the guide recess each have a curvature with a radius of curvature in the direction of the depth of recess, which radius corresponds approximately to the distance of the respective side wall from the pivot axis. If, as is particularly preferred, the side surfaces of the guide projection then each have a curvature in the direction of the projection height, which corresponds approximately to the distance of the respective side surface from the pivot axis, it can be achieved that a jam-free adjustment is ensured even when the assembly according to the invention is subjected to high loads , If - as is particularly preferred - the recess depth and the projection height are dimensioned such that the guide projection is in engagement with the guide recess over the entire adjustment range, these measures can be used without jamming with simultaneous high load capacity of the assembly according to the invention over the entire adjustment range be guaranteed.

In a preferred embodiment of the assembly according to the invention, the mounting part has at least one bore for a fastening means in the region of the pivot axis. In this embodiment, a fastening means, for example a fastening screw, can thus be provided, with which holding forces for the mounting part are introduced into a frame or into a wing in the region of the pivot axis. Since - as already explained above - holding forces are transmitted from the hinge flap into the assembly part by the interaction of the sliding block and the undercut groove, ie in the area of the swivel axis, these measures can now be transferred to the Wings or the frame are introduced without larger levers acting, as can be the case, for example, if there are larger distances between the bore and the pivot axis. This can be advantageous to increase the load capacity of the assembly.

It is then particularly preferred to provide a recess on the hinge tab through which the at least one fastening means can be inserted and actuated in the bore. This is because assembly of the assembly according to the invention on a sash or on a frame is then also possible with a belt tab preassembled on the assembly part, which can facilitate the handling of the assembly according to the invention.

In a preferred embodiment of the assembly according to the invention, the first adjusting means comprises a pressure screw which is provided in a first threaded bore of the hinge flap spaced from the pivot axis and which is supported on the mounting part. A rotary actuation in the sense of screwing the pressure screw into the threaded bore thus leads to a pivoting of the hinge flap about the pivot axis in the sense of an enlargement of the adjustment angle. In this embodiment of the assembly according to the invention, the first adjusting means further comprises a tension screw which comprises a head with an abutment surface. This tension screw is preferably provided in a second threaded bore of the mounting part, spaced apart from the pivot axis, and penetrates the hinge flap in an elongated opening, preferably parallel to the longitudinal axis of the groove. Since the head is supported with its abutment surface on the hinge flap, actuation of the tension screw in the sense of screwing in leads to a swiveling of the hinge flap in the sense of a reduction in the adjustment angle. By countering the pressure screw and tension screw, the hinge flap can be blocked against pivoting relative to the mounting part and thus a wing can be fixed relative to a frame in an achieved, horizontal adjustment position.

In a further preferred embodiment of the assembly according to the invention, a second adjustment means is provided, with which the hinge tab can be displaced relative to the assembly part in the direction of the longitudinal axis of the groove. Because of this measure, an adjustment adjustment in the direction of the hinge axis - also called vertical adjustment - possible.

For this purpose, the second adjusting means can have a support screw which is screwed from one end into a thread of the undercut groove and on which the sliding block is supported. Vertical adjustment is possible by turning the support screw. In order to be able to fix the hinge flap relative to the assembly part in a vertical adjustment position that has been reached, a counter screw is provided, which is screwed into the thread of the undercut groove from the other end and presses the sliding block against the support screw. In practice, the lock screw will be tightened when the desired vertical adjustment position has been achieved using the support screw.

The invention also extends to a band for hinge-jointed connection of a wing on a frame to a module with an assembly according to the invention.

The embodiment of the hinge according to the invention, designated 100 as a whole in the drawing (hereinafter, hinge 100) comprises a sash hinge part 1 and a frame hinge part 2. The hinge 100 serves to connect a hinge joint, not shown in the drawing, about a hinge axis S. put wing on a frame, also not shown.

As can be seen in particular in FIGS. 2 and 3, the frame hinge part 2 is formed in two parts in the case of the hinge 100: in relation to an arrangement in which the hinge axis runs approximately perpendicularly, it comprises a lower hinge part 3 around an upper hinge part 4. Each of the lower and upper band parts 3, 4 comprises a fastening part 5, 6, which is integrally connected to a hinge part 7, 8. The fastening parts 5, 6 serve to fasten the lower and the upper band parts 3, 4 to a fastening surface of a frame, not shown in the drawing. For this purpose, a lower and an upper clamping part 9, 10 are provided, by means of which a non-positive connection with the frame, not shown, can be achieved by screwing clamping screws 11 into threaded bores 12 of the clamping parts 9, 10. Further fastening screws 13, which are screwed into the frame, are also provided for a form-fitting fastening. For this purpose, the fastening screws 13 are designed as self-drilling or self-tapping screws.

The hinge parts 7, 8 each include a bore 14 which serve to receive a hinge pin 15 defining the hinge axis S. The wing hinge part 1 comprises an assembly 16. This in turn comprises a mounting part 17 which can be mounted on a mounting side of the wing not shown in the drawing.

The assembly 16 further comprises a hinge tab 18 which can be fastened to the mounting part 17. Furthermore, an undercut groove 19 is provided with a groove opening 20 and with a longitudinal axis A, which extends parallel to the hinge axis S and which is arranged on the assembly part 17 in the case of the band 100 (see in particular FIG. 7). Accordingly, the band tab 18 comprises a sliding block 21 which engages in the undercut groove 19 of the mounting part 17.

A hinge part 29 is formed on the hinge flap 18 and has a bore 22 through which the hinge pin 15 extends when the sash hinge part 1 is connected to the frame hinge part 2.

In the case of the band 100, the mounting part 17 comprises a guide recess 23 which is arranged at a distance from the undercut groove 19 in the direction perpendicular to the longitudinal axis A of the groove. The guide recess 23 has a recess length I, which extends over the total extent G of the mounting part 17.

Furthermore, 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 band tab 18 includes a guide projection 26 which engages in the guide recess 23. It has a projection length v which corresponds to the total extent of the band tab 18. Its projection height h 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 each have a curvature with a radius of curvature r, r ', which is approximately the distance between the respective side walls 24, 25 from a pivot axis B, around which the hinge flap 18 in the undercut groove 19 is pivotable, corresponds. In the assembly 16 shown, the pivot axis B and the longitudinal axis A lie on one another.

The side surfaces 27, 28 of the guide projection 26 each have a curvature which corresponds approximately to the distance r, r 'of the respective side surface from the pivot axis B, so that the side surface 27 on the side wall 24 and the side surface 28 on the side wall 25 are at least almost lie flat.

The groove opening 20 is adapted to the contour of the sliding block 21 in such a way that the hinge flap can be pivoted about the pivot axis B by an adjustment angle a. The maximum adjustment angle is shown in FIG. 4, the minimum adjustment angle a is 0 °. The recess depth t and the projection height h are dimensioned such that the guide projection 26 is in engagement with the guide recess 23 over the entire adjustment range J, where 0 ° <= J <= a applies.

The assembly 16 comprises a first adjustment means 30, with which the band flap 18 can be pivoted about the pivot axis B relative to the mounting part 17 by the adjustment angle a in the adjustment region J. For this purpose, it has a pressure screw 31 which is provided in a first threaded bore 32 of the hinge flap 18 spaced from the pivot axis B and is supported on the mounting part 17 (see in particular FIGS. 5 and 7).

Furthermore, the first adjustment means comprises a tension screw 33, which has a head 34 with an abutment surface 35. The tension screw is screwed into a second threaded bore 36 of the mounting part 17 spaced from the pivot axis B. It penetrates the band tab 18 in an opening 37, the head 34 of which is supported on the band tab 18 with its abutment surface 35. The opening 37 is elongated in the direction parallel to the hinge axis S.

The assembly 16 further comprises a second adjusting means 38, by means of which the band tab 18 can be displaced relative to the mounting part 17 in the direction of the longitudinal axis A of the groove. For this purpose, the second adjusting means comprises a support screw 39 which is screwed into a thread 40 of the undercut groove 19 from one end and on which the sliding block 21 is supported. Furthermore, the second adjusting means 38 has a counter screw 41, which is screwed from the other end into a thread 42 of the undercut groove 19 and presses the sliding block 21 against the support screw 39.

In order to reduce the friction between the hinge part 29 of the wing hinge part 1 and the hinge parts 7, 8 of the frame hinge part 2 and the hinge pin 15, slide bushes 43 are inserted into the bore 22 of the hinge part 29 and can be made, for example, from a plastic material.

To fasten the wing hinge part 17 to a wing (not shown in the drawing), a clamping part 44 is again used, the clamping action of which is brought about by means of clamping screws 45, which are screwed through bores 46 of the mounting part 17 into threaded bores 47 of the clamping part 44 , In addition, fastening screws 48 are provided, which are screwed into the wing. They are again intended as self-tapping or self-drilling screws. The fastening screws 49 are provided in the region of the pivot axis B. In order to be able to insert the fastening screws 49 into bores 50 provided for this purpose in the mounting part 17, the band tab 18 has a recess 51. The slot nut 21 is divided into two due to the recess 51. The hinge flap 18 is fastened to the mounting part 17 with the aid of mounting screws 52, which are screwed through openings 53 of the hinge flap 18, which are elongated in the direction parallel to the hinge axis S, into threaded bores 54 of the mounting part. To adjust the band tab 18 with respect to the mounting part 17 in the horizontal or vertical direction, the mounting screws are loosened and tightened again after the adjustment position has been reached, in order to fix the band tab 18 again.

In the case of the hinge 100, the assembly 16 according to the invention is provided on the side of the wing hinge part 1. It goes without saying that instead or in addition, the frame hinge part 2 can be equipped with an assembly 16 according to the invention. Bezuaszeichenliste:
