Abstract

The invention relates to a five-, six- or seven-pin hinge, wherein the wall-side hinge housing (4, 16, 26, 31) can be of very flat design in that, when the hinge is in the closed position, the position of the leaf-side lever end (13) of the wall-side main lever (7, 21, 25, 34) relative to the leaf-side lever end of the leaf-side main lever (6, 18, 28, 36), is offset at the leaf in the direction perpendicular to the hinge face towards the leaf by no more than the diameter of the pivot pin of the pivot axis (10, 23) of the leaf-side main lever (6, 18, 28, 36), and when the hinge is opened 180°, the position of the leaf-side lever end (13) of the wall-side main lever (7, 21, 25, 34) relative to the position of the pivot axis (10, 23) of the leaf-side main lever (6, 18, 28, 36) is offset at the leaf in the direction perpendicular to the hinge face away from the leaf by more than the diameter of the pivot pin of said pivot axis (10, 23).

Description

hinge

The invention relates to a hinge which is to be arranged in a concealed manner at an opening in a wall in order to pivotably hold a leaf on the wall.

"Concealed" in this context means that the hinge is essentially not visible when the wing is closed, since those of its parts which are not arranged sunk in the wing or wall anyway are covered by an end face of the wing then facing the wall.

For the opening and closing movements of the wing, hinges of this type lead the wing relative to the wall not only in a rotary (i.e. purely arc-shaped -) relative movement, but in a combination of rotary and translatory relative movement. In this way it is easy to achieve that the sash can be opened up to 180° without colliding with the wall.

Five, six and seven-axis door hinges for concealed installation - as they will also turn to ver in construction according to the present - are known to have two main levers, one of which can be referred to as a wall-side main lever and the other as a wing-side main lever, where both main levers each have a wall-side and a wing-side lever end. The wall-side main lever is held with its wall-side lever end on the wall only rotatably movably mounted, and the wing-side Haupthe lever is held rotatably with its wing-side lever end on the wing from finally rotatably. The wing-side lever end of the wall-side main lever is rotatable and translationally displaceable on the wing. The wall-side lever end of the wing-side main lever is held on the wall so that it can be rotated and displaced in a translatory manner. In addition, the two The main levers are held together so that they can only rotate, with the relevant pivot axis lying between the wall-side end and the wing-side end of the two main levers.

There are two common designs for said mounts, which allow rotation and translational displacement. In one construction, the relevant end of the main lever is connected exclusively pivotably to one end of an additional lever, and the second end of the additional lever is connected exclusively pivotably to the wall or the wing. In the second common design, said lever end of the main lever is connected to the wall or the wing by a slotted guide - ie by a combination of a sliding groove and guide pins projecting into it. In the design with link guide, the movement path of the affected end of the main lever is not limited to arcs of a circle, but it cannot extend out of the hinge housing - which means that the hinge housings of hinges with link guide are usually deeper than those of hinges with an additional lever. If two additional levers are used - and therefore no link guide - the hinge has seven axes. If no additional lever is used and two link guides are used, the hinge is five-axis. If an additional lever is only used on the wall side or only on the leaf side, the hinge is six-axis.

All said pivot axes are parallel to each other and all said translatory directions of movement lie in planes to which the pivot axes are normal.

The exact path of the relative movement between the sash and the wall during the opening and closing movement depends on the positioning of the individual pivot axes and, if applicable, the positions and path shapes of the slotted guides.

EP 1577474 A2 shows several construction variants of a five-axis concealed hinge. At least the outer boundary surfaces The wall-side and the sash-side hinge housing part of the hinge are designed to be essentially mirror-symmetrical to one another and are also mirror-symmetrical to one another when the sash is closed. Based on the extent of the translational movement in which the sash is guided by the hinge relative to the wall, the dimensions of the hinge housing parts normal to the wall plane are relatively small, while the dimensions parallel to the wall plane or sash plane and normal to the pivot axes are relative are high. The latter often leads to high processing costs, especially in the area of the wall.

EP 2570575 Bl shows several construction variants of a seven-axis concealed hinge. In this case, too, the dimensions of the hinge housing parts normal to the wall plane are relatively small, while the measurements lying parallel to the wall plane or wing plane and normal to the pivot axes are relatively high.

EP 2 476 834 Bl again shows several construction variants of a five-axis concealed hinge, with the wing being closed the mutually facing hinge housing surface sides of the wing-side hinge housing part and the wall-side hinge housing part are arranged somewhat offset relative to one another normal to the wall plane. Otherwise, it also applies here that the dimensions of the hinge housing parts that are normal to the wall plane are relatively small, while the dimensions that are parallel to the wall plane or leaf plane and normal to the pivot axes are relatively large.

EP 1754 848 A2 describes a hinge for concealed construction, which differs in principle from hinges according to the documents mentioned above. It in turn has two levers, which are pivotally mounted in each case at a central longitudinal region aneinan and each with one end at one wall-side housing part are kept stored and are kept stored at the other end on the wing-side housing part. However, the levers are very different from each other in that one lever is only pivotably connected to the wall or sash at both ends, while the other lever is pivotable at both ends and also slidable with the wall or sash. connected to the wing. With otherwise comparable framework conditions, this leads to larger hinge housings.

For the further description, the following terms are introduced with regard to location and direction definitions:

The "wall opening side" of a structure is that side portion of the structure which is offset from the center portion of the structure in the direction normal to the plane of the wall in which the wing pivots out of the wall during its opening movement. The side of the structure opposite the wall opening side is the "wall closing side".

The "wing opening side" of an assembly is that side portion of the assembly which is offset from the central portion of the assembly in the direction normal to the plane of the wing in which the wing pivots during its opening movement. The side of the structure opposite the wing opening side is the "wing closing side".

The "hinge surface of the wing" is that face of the wing which is normal to the plane of the wing and to which the wing-side hinge housing of the hinge is attached.

The "reveal surface" is that normal to the wall plane lying delimitation surface of the door opening in the wall to which the wall-side hinge housing of the hinge is attached. The "wing direction" is that direction parallel to the plane of the wing, normal to the hinge surface of the wing, pointing into the wing from the hinge surface of the wing.

The "wall direction" is the direction parallel to the plane of the wall, which is normal to the reveal surface and points into the wall, i.e. away from the door opening.

Depending on the context, the term "pivoting axis" describes either the infinitely thin straight line, which is the axis around which one body can be pivoted relative to another, or a - usually circular-cylindrical - axle bolt, which is part of the bearing for the guided pivoting movement of two bodies each other is

Especially with building doors - and not with furniture doors - a door opening in a wall is always framed with a frame, i.e. a door frame immovably connected to the wall. In the rest of the text, this border is generally not mentioned separately; instead, it is simply meant with the designation "wall".

General rules for determining the axis of the hinges can be found in the first three of the documents mentioned above: a The pivot axis of the wall-side main lever opposite the wall is on the wall opening side of the wall-side hinge housing. b The pivot axis of the wing-side main lever opposite to the wing is on the wing-opening side of the wing-side hinge case. c When the sash is closed, the pivot axis of the two main levers is adjacent to each other in the area of the wall closing side of the hinge housing of the hinge. d When the sash is closed, the wall-side lever end of the sash-side main lever lies in the wall-closing half of the wall-side hinge housing. e When the sash is closed, the sash-side lever end of the wall-side main lever lies significantly further in the sash-side hinge housing in the direction of the sash than the pivot axis of the sash-side main lever. During the opening movement of the leaf, the movement of the leaf-side lever end of the wall-side main lever has a movement component opposite to the leaf direction. f When the sash is closed, the wall-side lever end of the sash-side main lever in the wall direction is significantly further inside the wall-side hinge housing than the pivot axis of the wall-side main lever. g During the opening movement of the sash, the movement of the wall-side lever end of the sash-side main lever has a movement component opposite to the direction of the wall. h During the opening movement of the sash, the movement of the wall-side lever end of the sash-side main lever has a movement component away from the wall-closing side towards the wall-opening side.

The main task on which the present invention is based is to design a concealed, five-, six- or seven-axis hinge in such a way that it is possible, with otherwise the same functionality and otherwise the same installation dimensions, to increase the dimensions of the wall-side hinge housing part of the crowd niers to be significantly smaller in the direction of the wall than in the case of the hinges discussed in accordance with the prior art.

To solve the task, it is proposed to form the hinge according to the aforementioned general rules a to e as well as g and h, but not to meet the aforementioned rule f, but instead:

1. - determine the axis position of the wall-side lever end of the sash-side main lever in the direction of the wall in such a way that, when the sash is closed, it is only a maximum slightly further away from the reveal surface in the wall direction than the axis position of the pivot axis of the wall-side main lever on the wall-side hinge housing, and that

2. - the axis position of the wall-side lever end of the wing-side main lever when the wing is open 180° compared to the axis position of the pivot axis of the wall-side main lever on the wall-side hinge housing is offset by more than the diameter of this pivot axis against the wall direction.

"Axle position" in this context means the position of each straight line (infinitely thin straight line) about which the main lever in question can be pivoted relative to the other parts resting against the respective end of the lever.

This means that when the sash is closed, the position of the wall-side lever end of the sash-side main lever can be arranged very close to the reveal surface, ie at the opening area of the wall-side hinge housing. As a result, the dimension of the wall-side hinge housing can be made very narrow in the wall direction. This results in the Monta ge of the hinge on a wall, the desired advantage that no or only a small recess has to be formed on the surface enclosing the wall opening to accommodate the wall-side hinge housing of the hinge. This will counter- simpler and more cost-effective frames than the prior art, and/or the cost of installing the wall-side hinge housing of the hinge is significantly reduced.

Contrary to common expectations, despite the surprising positioning of the wall-side lever end of the sash-side main lever when the sash is closed in the opening area of the wall-side hinge housing, the trajectory of the sash during its opening movement can be adjusted in such a way that it does not collide with the wall and that there are no dangerous hazards in the hinge either Forces or jamming occur.

The invention is explained in more detail using drawings of exemplary embodiments:

Fig. 1: shows a first example according to the invention

Hinge in the installation situation in a sectional view with a viewing direction parallel to the pivot axes in three partial images, namely with an opening angle of 0°, 90° and 180°.

Fig. 2: shows a perspective view of the hinge of

Fig. 1 alone with an opening angle of 180°.

Fig. 3: shows a second example according to the invention

Hinge in the installation situation in a sectional view with a viewing direction parallel to the pivot axes. In solid lines, the hinge is shown in the closed condition; the hinge at an opening angle of 180° is shown in dashed lines.

Fig. 4: shows a third in the same view as the hinge of Fig. 3.

Fig. 5: shows a fourth example according to the invention

Hinge in the same view as the hinge of Fig. 3. The arrangement of FIG. 1 shows a wall 1, a leaf 2 and a hinge 3 connecting these two. The hinge 3 has a hinge housing 4 on the wall side and a hinge housing 5 on the leaf side. Other parts of the hinge 3 include a wall-side main lever 6, a wing-side main lever 7, a wall-side additional lever 8 and a wing-side link guide 9.

The general design rules a to e as well as g and h listed above are briefly demonstrated again using Fig. 1: a The pivot axis 10 of the wall-side main lever 6 opposite the wall 1 is on the wall opening side of the wall-side hinge housing 4. b The pivot axis 11 of the main lever 7 on the wing side opposite the wing 2 is on the wing opening side of the hinge housing 5 on the wing side When sash 2 is closed, the wall-side lever end 13 of the sash-side main lever 7 is in the wall-closing half of the wall-side hinge housing 4 wing-side main lift els 7. During the opening movement of the wing 3, the movement of the wing-side lever end 14 of the wall-side main lever 6 has a movement component opposite to the wing direction, ie out of the wing-side hinge housing 5. g During the opening movement of the leaf 3, the movement of the wall-side lever end 13 of the leaf-side main lever has a movement component opposite to the wall direction. h During the opening movement of the leaf 3, the movement of the wall-side lever end 13 of the leaf-side main lever 7 has a movement component away from the wall closing side towards the wall opening side.

Compared to the prior art, the hinge of FIG. 1 differs according to the invention by the following two features:

1. Prior art feature f mentioned above is not satisfied. Instead, in the specific case when the sash 3 is closed, the axis position of the wall-side lever end 13 of the sash-side main lever 7 is the same distance away from the reveal surface 15 in the wall-side hinge housing 4 inside as the axis position of the pivot axis 10 of the wall-side term main lever 6 on the wall-side hinge housing 4.

2. When the sash 3 is open by 180°, the axis position of the wall-side lever end 13 of the wing-side main lever 7 is offset from the axis position of the pivot axis 10 of the wall-side main lever 6 on the wall-side hinge housing 4 by more than the diameter of this pivot axis 10 against the direction of the wall, i.e. it is located by more than the diameter of the pivot pin forming the pivot axis 10 closer to the center of the opening in the wall 1 to be closed by the wing 2 than the pivot axis 10.

In the crowd according to the invention shown in Fig. 1 and Fig. 2 nier are the hinge housing 4, 5 as in the wall 1 and the

Wing 2 set pots formed or arranged. The wing-side lever end 14 of the wall-side main lever 6 can be pivoted and translated in a translatory manner on the wing-side hinge housing 5 by the wing-side link guide 9 leads held. The wall-side lever end 13 of the wing-side main lever is held on the wall-side hinge housing 4 by the wall-side additional lever 8 pivotably and translationally ver slidably guided.

As with all other constructions shown according to the invention, the dimension of the wall-side hinge housing (4) in the direction of the wall (thus possibly the depth of the wall-side hinge housing pot) is significantly lower than comparable constructions according to the prior art.

Fig. 3 shows a hinge design according to the invention in which the wall-side hinge housing 16 is arranged relatively far from the wall opening side of the wall 1 away. As outlined, this is particularly useful if the wall 1 is provided with a covering layer 17 on the wall opening side, which should not be weakened by a recess such as that required for the installation of the hinge housing 16 on the wall side.

In this case, the sash-side lever end of the sash-side main lever 18 is held on the sash-side hinge housing 19 by a sash-side additional lever 20 such that it can pivot and be moved in translation, and the wall-side lever end of the sash-side main lever 21 is on the wall-side hinge housing 16 in a local, i.e. wall-side, coolie So that the wall-side end of the sash-side main lever 21 can be moved counter to the direction of the wall beyond the reveal surface 15 for large opening angles of the sash 2, the wall-side link guide extends in an opening-side extension of the wall-side hinge housing 16 beyond the opening surface of the wall-side hinge housing 16 and thus through the reveal surface 15. According to the first characteristic rule of the present invention, when the sash 2 is closed, the axis position of the wall-side lever end of the sash-side main lever 21 in the wall direction is only slightly further away from the reveal surface 15 than the axis position of the pivot axis 23 of the wall-side main lever 18 on the wall-side hinge housing 16. In this context, "minor" means that the difference in distance is less than the diameter of the pivot pin of the wall-side main lever 18 forming the pivot axis 23 on the wall-side hinge housing 16. (The said diameter is typically 6 mm or more.)

According to the second characterizing rule of the present invention, the axis position of the wall-side lever end of the main lever 21 on the wing side, when the wing 2 is 180° open, is opposite to the axis position of the pivot axis 23 of the wall-side main lever 18 on the wall-side hinge housing 16 by more than the diameter of this pivot axis 23 offset from the direction of the wall.

Fig. 4 shows the application of the construction according to the invention on a leaf 24 with a rebated, i.e. stepped, end face and complementary edge surface of the door opening in the wall 1. As in the construction according to FIG Hinge housing 26 is held by an additional lever 27, and the wing-side lever end of the wall-side main lever 28 is held on the wing-side hinge housing 29 in a wing-side Ku lissenführung 30.

FIG. 5 shows an application of the construction according to the invention, in which the effect intended by the invention, namely reducing the effort for the assembly of the wall-side hinge housing, is taken to the extreme. In this case The wall-side Schar niergehäuse 31, which is in turn quite flat, does not need to be used in a recess of the wall 1 on the soffit surface 15, but the Schar niergehäuse 31 can be placed directly on the soffit surface 15 and fastened (screwed tight). When closing the wing gel 2, its hinge surface 32 moves so close to the reveal surface 15 that parts of the wall-side hinge housing 31 installed on the reveal surface 15 protrude behind the hinge surface 32, ie into the wing 2. So that this does not lead to any collisions, the wing-side hinge housing 33 is very deep, and the built-in components there are so deep inside that there is space in the area of the wing-side hinge housing 33 open to the hinge surface of the wing 2 for parts of the wall-side hinge housing 31 .

As in the construction according to FIG. 1, the wall-side lever end of the wing-side main lever 34 is held on the wall-side hinge housing 31 by an additional lever 35, and the wing-side lever end of the wall-side main lever 36 is held on the wing-side hinge housing 33 in a wing-side link guide 37.

When specifying the positions of the various lever ends and the design of levers, link tracks and hinge housing shapes, simulations in drawings are typically carried out in several iteration steps. An exemplary procedure is briefly explained in the form of a list:

- Specify the geometry of the sash and wall, as well as the size and position of the hinge housing on the sash and wall.

- Determine two triangles, where the corner points are relative to each other in the same way as the pivot axes on each of the main levers (pivot axis on the sash-side lever end, pivot axis on the wall-side lever end, pivot axis which connects the two main levers with each other) - Assume the position of the sash to the wall at the opening angles of 0°, 45°, 90° and 180°, assuming the position of the two triangles representing the two main levers and marking the respective positions of the lever ends on the wall or sash.

- Draw trajectories on the wall and sash which connect the position markings of the lever ends and can be assumed to be the trajectories of these lever ends.

- Take the forms of the two main levers and, if necessary, the additional levers and go through the motion simulation with them. Change the shapes of the levers and, if necessary, the guideways of the movements of the lever ends until the movement simulations no longer lead to collisions.

Most applications for hinge constructions according to the invention are probably in building doors. In principle, however, the invention can also be advantageously applied to building windows and furniture doors. Therefore, it is hereby clarified that in this text the term "wall" refers to both building walls and walls of furniture, and that in this text the term "wing" refers to both pivoting door panels of building doors and pivoting window panels as also refers to hinged door panels of furniture.

In accordance with the principle of kinematic reversal, hinges according to the invention can also be used if the wing and wall are reversed compared to the previous description. This is primarily used when pivotable leaves with a large thickness are arranged on comparatively thin walls (eg thin partitions or cabinet heads). The third patent claim of the following patent claims, which is an independent patent claim, relates to such applications of inventive hinges in which the functions shown in the drawings and described in the accompanying description there is a kinematic reversal in that the wing and wall are reversed.
