Description

Structural component of hinge and hinge comprising same

Technical Field

The invention relates to a hinge (Band) for the hinged connection of a leaf to a frame about a hinge axis, comprising a fitting which can be fitted on a fitting side of the leaf or of the frame, comprising a hinge leaf which can be fastened to the fitting, wherein one of the fitting and the hinge leaf has a side recess which comprises a recess opening and a recess longitudinal axis which extends parallel to the hinge axis, while the other of the fitting and the hinge leaf has a slot piece which engages in the side recess of the fitting, and the structural component comprises first adjusting means with which the hinge leaf can be pivoted about the hinge axis relative to the fitting by an adjustment angle within a first adjustment range.

The invention also relates to a hinge comprising such a structural assembly.

Background

A hinge with such a structural component is known from EP 2725174 a 1. Since the hinge leaf can be pivoted about the pivot axis relative to the fitting by an angle of adjustment, the wing in the frame can be adjusted in a simple manner in a direction perpendicular to the hinge axis by actuating the first adjusting means, also referred to as horizontal adjustment. However, in practice, it has been found that the hinge with the structural assembly described is worth improving in terms of its usability in the case of heavier wings.

Disclosure of Invention

The object of the invention is therefore to provide an improved structural component of the type mentioned at the outset and a hinge comprising said structural component.

The object is achieved by the structural component according to the invention and by the hinge according to the invention.

In a structural component of a hinge according to the invention for the articulated connection of a wing to a frame about a hinge axis, comprising a fitting part which can be fitted on a fitting side of the wing or of the frame, comprising a hinge leaf which can be fastened to the fitting part, wherein one of the fitting part and the hinge leaf has a lateral recess which comprises a recess opening and comprises a recess longitudinal axis which extends parallel to the hinge axis, and the other of the fitting part and the hinge leaf has a slot piece which engages in the lateral recess of the fitting part, and the structural component comprises first adjusting means with which the hinge leaf can be pivoted about a pivot axis relative to the fitting part by an adjustment angle within an adjustment range, one of the fitting part and the hinge leaf comprising a guide recess, the guide recess is arranged at a distance from the 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 void depth is defined by two sidewalls. The other of the fitting and the hinge leaf comprises a guide projection which engages in the guide recess and engages with the guide recess in the adjustment range. The guide projection has a projection length and a projection height. The protrusion height is defined by two sides.

In the assembly according to the invention, the guide projections and the guide recesses provide means by which additional retaining forces can be introduced from the hinge leaf into the fitting without this hindering or impairing the adjustability.

The expression "one of the fitting and the hinge leaf" means that the expression refers to measures which can be provided either on the fitting or on the hinge leaf. Accordingly, the expression "the other of the fitting and the hinge plate" is intended to mean that the measures referred to in the preceding expression are then respectively located on the other structural part, i.e. either on the hinge plate or on the fitting.

Preferably, the guide recess is formed such that its recess length extends over the total extension of one of the fitting and the hinge leaf. Accordingly, the guide projection is preferably designed such that its projection length extends over the total extension of the other of the fitting and the hinge plate. This measure is intended to increase as much as possible the area over which the guide projection overlaps the guide recess in order to reduce the surface load with regard to the highest possible load capacity of the structural component according to the invention.

In this context, it is also preferred if the side walls of the guide recess each have a curvature in the direction of the recess depth, which comprises a radius of curvature, which corresponds approximately to the distance of the respective side wall from the pivot axis. As is particularly preferred, the side faces of the guide projection can then, if in each case in the direction of the projection height, have a curvature corresponding approximately to the distance of the respective side face from the pivot axis, be designed such that an undamped adjustment is ensured even in the case of high loads of the structural assembly according to the invention. As is particularly preferred, if the gap depth and the projection height are dimensioned such that the guide projection engages with the guide gap over the entire adjustment range, it is possible on the basis of this measure to ensure a non-clamping displaceability of the structural component according to the invention over the entire adjustment range while high loads are present.

In a preferred embodiment of the assembly according to the invention, the fitting has at least one hole for a fastening means in the region of the pivot axis. In this embodiment, therefore, fastening means, for example fastening screws, are provided, with which the holding force for the fitting is introduced into the frame or the wing in the region of the pivot axis. As already mentioned above, because the retaining force is transmitted from the hinge leaf into the fitting (i.e. in the region of the pivot axis) by the interaction of the slot blocks with the side pockets, it is now possible on the basis of this measure to introduce said retaining force into the wing or into the frame without a large lever action, which is possible if there is a large distance between the opening and the pivot axis. This is advantageous for increasing the load capacity of the structural assembly.

It is then particularly preferred if a recess is provided on the hinge leaf, through which the at least one fastening means can be introduced into the opening and can be actuated. The assembly of the structural component according to the invention on a wing or on a frame can thus be carried out even when the hinge plate is preassembled on the assembly, which facilitates the handling of the structural component according to the invention.

In a preferred embodiment of the assembly according to the invention, the first adjusting means comprise a pressure screw which is arranged in a first threaded bore of the hinge leaf at a distance from the pivot axis and is supported on the fitting. In the sense of screwing the compression screw into the threaded hole, the rotational actuation thus results in pivoting the hinge plate about the pivot axis in the sense of an enlarged adjustment angle. In this embodiment of the assembly according to the invention, the first adjusting means furthermore comprise a tensioning screw which comprises a head with a seat surface. Preferably, the tensioning screw has a head with a seat surface, is arranged in a second threaded bore of the fitting at a distance from the pivot axis and passes through the hinge leaf in a through-hole, which is preferably elongate in a direction parallel to the longitudinal axis of the slot. Since the head rests with its seat surface on the hinge leaf, actuating the tensioning screw in the sense of screwing in causes the hinge leaf to pivot in the sense of reducing the adjustment angle. By means of a locking (Kontern) hold-down screw and a tensioning screw, pivoting of the hinge leaf relative to the fitting can be prevented and the wing can thus be fixed in the horizontal adjustment position achieved relative to the frame.

In a further preferred embodiment of the assembly according to the invention, a second adjusting means is provided, by means of which the hinge plate can be displaced in the direction of the longitudinal axis of the groove relative to the mounting part. On the basis of this measure, an adjustment in the direction of the hinge axis, also referred to as a vertical adjustment, is also possible with the structural component according to the invention.

For this purpose, the second adjusting means has a support screw which is screwed into the thread of the side groove from one end and is supported on the groove block. Vertical adjustment can be achieved by rotationally manipulating the support screw. In order to be able to fix the hinge leaf in the achieved vertical adjustment position relative to the fitting, a countersunk screw is provided which is screwed into the thread of the side groove from the other end and presses the groove block against the support screw. In practice, the countersunk-head screw is tightened if the desired vertical adjustment position is reached by means of the supporting screw.

The invention also relates to a hinge for the articulated connection of a wing to a frame about a hinge axis, comprising a structural component according to the invention.

Detailed Description

The embodiment of the hinge according to the invention (hereinafter referred to as hinge 100) shown as a whole in the figures comprises a wing hinge element 1 and a frame hinge element 2. The hinge 100 is used to connect a wing, not shown in the figures, to a frame, also not shown, in an articulated manner about a hinge axis S.

As can be seen in particular in fig. 2 and 3, in the hinge 100, the frame hinge part 2 is formed in two parts: the frame hinge element, the arrangement extending substantially perpendicularly with respect to the hinge axis, comprises a lower hinge element 3 surrounding an upper hinge element 4. Each of the lower and upper hinge elements 3, 4 comprises a

fastening element

5, 6, which is connected in one piece to a hinge element 7, 8. The

fastening elements

5, 6 serve to fasten the lower and upper hinge parts 3, 4 to fastening surfaces of a frame, not shown in the figures. For this purpose, lower and

upper clamping elements

9, 10 are provided, by means of which a force-fitting connection to a frame, not shown, can be achieved by screwing a clamping screw 11 into a threaded hole 12 of the

clamping elements

9, 10. Further fastening screws 13 are provided which are screwed into the frame for form-fitting fastening. For this purpose, the fastening screw 13 is designed as a self-drilling screw or a self-tapping screw.

The hinge parts 7, 8 each comprise a hole 14 for receiving a hinge pin 15 defining a hinge axis S.

The wing hinge member 1 includes a structural assembly 16. The structural component also comprises a fitting 17 which can be fitted on the fitting side of a wing, not shown in the figures.

Furthermore, the structural component 16 comprises a hinge 18, which can be fastened to the fitting 17. Furthermore, a lateral recess 19 (see in particular fig. 7) is provided in the hinge 100 on the fitting 17, said lateral recess comprising a recess opening 20 and comprising a recess longitudinal axis a arranged to extend parallel to the hinge axis S. Accordingly, the hinge plate 18 includes a slot block 21 that fits into the side recess 19 of the fitting 17.

Formed on the hinge leaf 18 is a hinge part 29 which has an opening 22 through which the hinge pin 15 extends if the wing hinge part 1 is connected to the frame hinge part 2.

In the hinge 100, the fitting 17 comprises a guide recess 23, which is arranged at a distance from the lateral recess 19 in a direction perpendicular to the longitudinal axis a of the recess. The guide recess 23 has a recess length l which extends over the overall extension G of the fitting 17.

Furthermore, the guide recess 23 has a recess depth t perpendicular to the groove longitudinal axis a and delimited by two side walls 24, 25 (see in particular fig. 7).

The hinge plate 18 includes a guide projection 26 embedded in the guide space 23. The guide projection has a projection length v corresponding to the overall extension of the hinge plate 18. The projection height h of the guide projection is delimited by two side faces 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 corresponds approximately to the distance of the

respective side wall

24, 25 from the pivot axis B about which the hinge leaf 18 can be pivoted into the side recess 19. In the illustrated construction assembly 16, the pivot axis B overlaps the groove longitudinal axis a.

The flanks 27, 28 of the guide projection 26 also each have a curvature which corresponds approximately to the distance r, r' of the respective flank from the pivot axis B, so that the flank 27 at least almost rests against the side wall 24 and the flank 28 at least almost rests against the side wall 25.

The slot opening 20 is adapted to the contour of the slot piece 21 in such a way that the hinge leaf can be pivoted about the pivot axis B by an adjustment angle α. In fig. 4, the maximum adjustment angle is shown, the minimum adjustment angle α being 0 °. The recess depth t and the projection height h are dimensioned such that the guide projection 26 engages with the guide recess 23 over the entire adjustment range J, where 0 ° < ═ J < ═ α.

The assembly 16 comprises a first adjusting means 30, with which the hinge plate 18 can be pivoted about the pivot axis B relative to the fitting 17 by an adjustment angle α in an adjustment range J. For this purpose, the first adjusting means have a pressure screw 31 which is arranged in a first threaded hole 32 of the hinge leaf 18 at a distance from the pivot axis B and is supported on the fitting 17 (see in particular fig. 5 and 7).

Furthermore, the first adjusting means comprise a tensioning screw 33 having a head 34 comprising a seat surface 35. Said tensioning screw is screwed into a second threaded hole 36 of the fitting 17, spaced apart from the pivot axis B. The tensioning screw penetrates the hinge plate 18 in the through-hole 37, wherein the head 34 of the tensioning screw is supported with its seat surface 35 on the hinge plate 18. The through-hole 37 is formed as an elongated hole in a direction parallel to the hinge axis S.

The assembly 16 furthermore comprises a second adjusting means 38, with which the hinge plate 18 can be displaced relative to the mounting part 17 in the direction of the slot longitudinal axis a. For this purpose, the second adjusting means comprise a supporting screw 39 which is screwed from one end into a thread 40 of the side groove 19 and on which the channel block 21 is supported. Furthermore, the second adjusting means 38 has a countersunk screw 41 which is screwed into a thread 42 of the side groove 19 from the other end and presses the groove block 21 against the supporting screw 39.

In order to avoid friction between the hinge part 29 of the leaf hinge part 1 and the hinge parts 7, 8 of the frame hinge part 2 and the hinge pin 15, a sliding sleeve 43, which can be made of plastic material, for example, is inserted into the bore 22 of the hinge part 29.

In order to fasten the leaf hinge 17 to a wing, which is not shown in the figures, the clamping element 44 is used again, the clamping action of which is performed by means of a clamping screw 45 which is screwed into a threaded hole 47 of the clamping element 44 through a hole 46 of the fitting 17. Fastening screws 48 are also provided, which are screwed into the wing. The fastening screw is in turn configured as a self-tapping screw or a self-drilling screw. The fastening screw 49 is arranged in the region of the pivot axis B. In order to be able to introduce the fastening screw 49 into the hole 50 of the fitting 17 provided for this purpose, the hinge leaf 18 has a recess 51. The channel block 21 is two-piece due to the recess 51. The hinge leaf 18 is fastened to the fitting 17 by means of fitting screws 52 which are screwed through holes 53 of the hinge leaf 18 in the form of long holes in a direction parallel to the hinge axis S into threaded holes 54 of the fitting. In order to adjust the hinge plate 18 in the horizontal or vertical direction relative to the fitting 17, the fitting screw is released and, after reaching the adjustment position, is again screwed in order to fix the hinge plate 18 in this way.

In the hinge 100, the structural component 16 according to the invention is arranged on the side of the leaf hinge element 1. It goes without saying that the frame hinge part 2 can be equipped with a structural component 16 according to the invention instead of or in addition to this.
