Description

The present invention relates to a fitting arrangement for a wing of a window, a door or the like having a wing portion adapted to be mounted on the wing and having a frame part adapted for attachment to a fixed frame. The wing part and the frame part are pivotally coupled together.

When mounting a window or door, it is very important that the sash is properly positioned in the frame. Only in this way can it be ensured that the window or the door can be closed correctly and that the optical impression disturbing uneven gaps between the frame and the wing are avoided.

In order to simplify the assembly of the window or the door, the fitting arrangement may comprise an adjusting unit, by which the relative position of the wing part and the frame part can be changed and / or by the position of a pivot axis to pivot about the wing part and the frame part are to be influenced. Such an adjusting unit can also be designed so that with its help a position of the frame part and / or the wing part on the frame or on the wing can be corrected. In other words, small inaccuracies of the frame and / or the wing as well as errors in attaching the fitting arrangement can be compensated by the adjusting unit.

When multiple conventional fitting assemblies are used to mount the wing in the frame, the problem arises that the operation of the adjustment unit of one fitting assembly results in stress in the adjustment units of the other fitting assemblies. As a result, even after a slight actuation of the adjusting unit of one of the fitting arrangements, the adjusting units of the other fitting arrangements also have to be readjusted. If this is omitted, the adjustment units block each other. An adjustment process is therefore a small-step iterative and consequently time-consuming process in fitting arrangements of conventional type.

The above-outlined problem occurs in particular in connection with longitudinal adjustment mechanisms of the adjusting units, by means of which the frame part and the wing part of a respective fitting arrangement are movable relative to one another parallel to their pivot axis. In fact, in the case of an adjustment process, the weight force of the wing is generally loaded on the fitting arrangements and thus ultimately also on components of the longitudinal adjustment mechanisms.

The US 2006/0179610 A1 discloses a fitting assembly having a longitudinal adjustment mechanism with a rotatable spindle held axially fixed in a housing of the assembly.

The WO 2005/075776 A1 describes a fitting arrangement with the features of the preamble of claim 1.

It is an object of the present invention to provide an improved fitting arrangement with an adjusting unit, by means of which the position of a wing in a frame can be adjusted more easily and more quickly.

The solution of this object is achieved by a fitting arrangement with the features of claim 1.

As already mentioned above, the fitting arrangement of the aforementioned type comprises a wing part and a frame part, which are pivotably coupled to one another about a pivot axis. The frame part and the wing portion are movable relative to each other for adjustment purposes by means of a longitudinal adjustment mechanism of an adjusting unit in a direction parallel to the pivot axis.

The frame part or the wing part comprises a fixedly connectable to the frame or with the wing base member. Between in loaded condition of the fitting assembly cooperating components of the base member and the longitudinal adjustment mechanism is provided in an unloaded state of the fitting assembly in a direction parallel to the pivot axis a mounting clearance. The mounting clearance determines a maximum relative offset between the frame part and the wing part.

In contrast to the complex iterative adjustment procedure of conventional type described above, it is possible when using the fitting arrangements according to the invention with mounting clearance to first attach a plurality of fitting arrangements on the wing and the frame and then position the wing by means of one of the fitting arrangements. The other fitting arrangements do not hinder this adjustment process, since their frame parts and wing parts are freely movable relative to each other due to the mounting clearance. After the wing is correctly positioned, the longitudinal adjustment mechanisms of the other fitting assemblies can be adjusted to load them as well. That is, their assembly game is passed through until the corresponding components of the respective base member and the associated longitudinal adjustment mechanism cooperate and thus this fitting arrangements thus develop a supporting effect, so that the first adjusted fitting arrangement is relieved.

Further embodiments of the invention are indicated in the description, the claims and the attached drawings.

The mounting clearance can be dimensioned such that the maximum relative offset between the frame part and the wing part between about 1 mm and about 10 mm, in particular between about 1 mm and about 5 mm, preferably between about 3 mm and about 10 mm, advantageously between about 3 mm and about 8 mm.

The longitudinal adjustment mechanism comprises a rotatably mounted adjustment shaft, which is drivable by an adjusting element or directly to a rotational movement, to effect a relative movement between the frame part and the wing part. An axis of rotation of the adjusting shaft is arranged parallel to the pivot axis.

The adjusting shaft has a shoulder which cooperates in a loaded state of the fitting arrangement with a provided on the base element lug element. Figuratively speaking, for example, the neck element is supported in a loaded state of the fitting arrangement on the shoulder of the Justierwelle, or vice versa. The loading of the fitting arrangement is thus transmitted through the shoulder and the correspondingly formed attachment element from the wing part to the frame part, or vice versa.

The adjusting shaft is movable in an unloaded state of the fitting arrangement relative to the base element in a direction parallel to the pivot axis.

According to the invention, the longitudinal adjustment mechanism cooperates with a carriage, wherein the frame part and / or the wing part are movable relative to the carriage. The adjusting shaft acts via a thread, in particular an external thread female thread mating, with the carriage together.

The longitudinal adjustment mechanism comprises a screw thread, which preferably has self-locking properties. The worm thread can be provided, for example, between an adjusting element which can be directly actuated by an operator and the adjusting shaft. The worm thread comprises a worm which is arranged on the adjustment element which can be actuated for adjustment purposes and in which a toothed wheel, which is arranged on the adjusting shaft, engages.

According to a structurally simple and inexpensive to produce embodiment, the base member is a component of a housing which receives the adjusting unit and in particular substantially completely covers. The housing may further comprise a component attachable to the base member and having a component cooperating with the component of the longitudinal adjustment mechanism in a loaded condition of the fitting assembly. In particular, said component of the cover component is formed complementary to the corresponding component of the base element.

Fig. 1 shows a fitting assembly 10, which serves for example for fixing a wing of a window, a door or the like to a corresponding frame. The fitting assembly 10 includes a wing portion 14 which is secured to the wing and a frame portion 12 which is secured to the frame. The wing part 14 and the frame part 12 are pivotally coupled together by an axle 16. The axle pin 16 thus forms a pivot axis of the fitting arrangement 10.

If the wing part 14 and the frame part 12 are fastened to the respectively associated component of a window or a door, the problem often arises that the wing is not correctly positioned in the frame. Although the positioning errors are usually quite small, they can hinder a correct closing of the window or the door. Apart from that, a bad centering of the wing in the frame disturbs the visual impression to a considerable extent.

In order to be able to subsequently correct the position of the wing in the frame, the fitting arrangement 10 comprises an adjustment unit with which the relative spatial arrangement of the wing part 14 and the frame part 12 can be adjusted. The adjusting unit is arranged substantially in the interior of the wing part 14, so that their mechanical components or the mechanisms for generating the various adjustment movements in Fig. 1 not to be seen. In Fig. 1 only adjustment screws 18, 18 'and a position indicator 20 can be seen.

The axle 16 is received by pivot bearings 24 of the frame part 12. The flap 22 projects into a body 14a of the wing portion 14. When the frame portion 12 is fixed to the frame, the wing associated with the wing portion 14 ultimately bears on the flap 22. By rotation the adjusting screw 18, the wing member 14 relative to the tab 22 in a direction parallel to the pivot axis of the fitting assembly 10 forming axis pin 16 are moved. If the fitting arrangement 10 is used, for example, in the case of a door, an adjustment of the height of the wing of the door in the frame can be adjusted by actuating the adjustment screw 18.

The position indicator 20 indicates in which position - relative to a direction parallel to the axle pin 16 - the tab 22 is relative to the body 14a of the wing portion 14 so that an operator can better observe the progress of the adjustment process. In other words, the position indicator 20 directly indicates in which direction and by what amount the body 14a is moved relative to the tab 22 and thus the frame part 12.

The adjusting screw 18 'allows an adjustment of the angle between a plane spanned by the tab 22 and a plane through the Wing part 14 spanned plane, according to below with reference to Fig. 8 is explained in more detail.

The adjustment screws 18, 18 'and the position indicator 20 are associated with markings to facilitate the operation of the adjustment of the fitting assembly 10. Further, the body 14a mounting holes 32, can be guided by the fastening elements - for example screws - for attachment of the wing portion 14 to the wing. Mounting openings 32 are also provided on a mounting plate 33 of the frame part 12.

Fig. 2 shows a further perspective view of the fitting assembly 10, whereby it can be seen that the body 14a of the wing portion 14 of a base portion 28 and a cover member 30 composed. The base part 28 and the cover part 30 form a housing and protect the mechanical components of the adjusting unit and therefore contribute to the robust design of the fitting arrangement 10.

The view of Fig. 2 allow the view of a mounting opening 34 of the housing, which is arranged on the side facing away from the frame part 12 of the body 14a. Through the mounting opening 34, a component of a Querjustierungsmechanismus the adjustment can be achieved in order to secure it in the course of a factory assembly of the fitting assembly 10, as shown in FIG Fig. 5 will be explained in more detail. The transverse adjustment mechanism serves to displace the tab 22 in a direction perpendicular to the pivot axis of the fitting assembly 10.

Fig. 3 illustrates the basically very simple construction of the frame part 12. In addition to the pivot bearings 24 includes the frame part 12th only the mounting holes 33 having the mounting plate 33. The frame part 12 includes no components of the adjusting unit.

Fig. 4 shows a view of the wing portion 14 with the cover part 30. It can be seen that the tab 22 protrudes into a carriage 36 which is movable in a direction parallel to the pivot axis of the fitting assembly 10 in the interior of the body 14 a of the wing member 14. In order to stabilize the movement of the carriage 36, the carriage 36 and portions of the base portion 28 and the lid portion 30 which are in direct contact with it are provided with complementary surface structures which allow said movement and reliably prevent the carriage 36 from moving in other directions. For example, a flat groove 38 is provided on the base part 28, which runs parallel to the axle pin 16. The carriage 36 is at its - in Fig. 4 not to be seen - underside provided with a complementarily shaped rib. A corresponding guide means comprising a rib 40 on the upper side of the carriage 36 is provided between the lid member 30 and the carriage 36.

The ribs 40 and the grooves 38 form - as based on Fig. 8 will be explained in detail below - also a bearing by which the tab 22 is pivotally mounted relative to the wing member 14.

In order to be able to move the wing part 14 and the slide 36 relative to one another parallel to the pivot axis of the fitting arrangement 10, a longitudinal adjustment mechanism 42 is provided which comprises the adjustment screw 18 already mentioned above. The adjusting screw 18 is radially outwardly provided with a worm 44, in which a gear 46 engages, which in turn is non-rotatably connected to an adjusting shaft 48. The adjusting shaft 48 projects into an opening of the carriage 36. The in the Carriage 36 projecting end of the adjusting shaft 48 is provided with an external thread which engages in a corresponding internal thread of the opening of the carriage 36.

Finally, the adjusting screw 18 is thus coupled via a worm thread and the above-described male / female combination with the carriage 36. A rotation of the adjusting screw 18 causes via the worm gear consisting of the worm 44 and the gear 46, a rotation of the adjusting shaft 48, via the above-mentioned external / internal thread combination with fixed frame part 12 in a movement of the wing member 14 in a direction parallel to the pivot axis of the fitting assembly 10 is implemented. By a suitable design of the threads involved, any over / under adjustment of Justierdrehbewegung the adjusting screws 18 can be realized in a movement of the carriage 36.

In contrast to conventional longitudinal adjustment mechanisms, the longitudinal adjustment mechanism 42 has the advantage that it does not move even when using the fitting assembly 10. The screw thread consisting of the worm 44 and the gear wheel 46 has self-locking properties. Although a pivotal movement of the fitting assembly 10 acts on the carriage 36. However, since the axis of rotation of the adjusting screw 18 is aligned perpendicular to the axis of rotation of the adjusting shaft 48 and a worm gear coupling the two said components 18, 48, also continuous loads of the carriage 36 does not lead to a Movement of the adjusting screw 18. In other words, a spatial displacement of the parts 12, 14 relative to each other in a direction parallel to the pivot axis can only be brought about when the adjusting screw 18 is actively actuated.

Fig. 5 shows a similar view of the frame part 14 as the Fig. 4 , However, parts of the carriage 36 have been removed to make the gear 46 remote and projecting into the carriage end of the adjusting shaft 48 recognizable. At the lower end of the adjusting shaft 48, an external thread 49 a is provided, which cooperates with a complementarily formed internal thread 49 b of the carriage 36. The threads 49a, 49b are used to implement a rotational movement of the adjusting shaft 48 in a lifting movement B1 of the wing member 14 parallel to the pivot axis of the fitting assembly 10th

The Fig. 5 also provides insights into the operation of a lateral adjustment mechanism 50, the purpose of which has already been mentioned above. In order to move the tab 22 in a direction perpendicular to the pivot axis of the fitting assembly 10 (transverse movement B2), a screw 52 is provided which cooperates with the tab 22. A head of the screw 52 can be reached through the adjusting hole 53. A rotation of the screw 52 causes the tab 22 is pulled into the carriage 36, which in Fig. 5 corresponds to a movement B2 in the image plane to the right, or is pushed away from the carriage 36, which in Fig. 5 corresponds to a movement B2 in the image plane to the left. In order to prevent the screw 52 from being accidentally completely unscrewed after a factory assembly of the fitting assembly 10, it is widened at its end facing away from the frame part 12. In order to achieve this end of the screw 52 for this purpose, the mounting hole 34 is provided.

In principle, the transverse adjustment mechanism can also be designed to be self-locking, differing from the design shown. Since the problem with respect to a loss of adjustment when using the fitting assembly - ie by pivoting the frame or wing part - Occurs in particular in connection with the longitudinal adjustment mechanism, it is sufficient in many cases, to provide only the latter with self-locking properties.

Fig. 6 shows a part of the longitudinal adjustment mechanism 42 in a detailed view. On display are, inter alia, the adjusting screw 18 with the worm 44, in which engages the arranged on the adjusting shaft 48 gear 46. In a loaded state of the fitting arrangement 10, the wing part 14 ultimately hangs on the tab 22 on the frame part 12 fixedly arranged on the frame. The adjusting shaft 48 plays a decisive role here. On her namely a shoulder 54 is formed on which in a loaded state of the fitting assembly 10, a projection 56 rests, which is integrally formed with the base part 28. The cover part 30 has a complementary projection 56, so that they together in an assembled state of the parts 28, 30 ultimately form a support ring which rests on the shoulder 54.

As already described above, rotation of the adjusting shaft 48 due to the threads 49a, 49b causes the wing member 14 to be raised or lowered. In this case, the adjusting shaft 48 is rotated by a rotation in the carriage 36 or rotated out of it, whereby the projection 56 is moved to the carriage 36 or moved away from it.

In Fig. 6 the longitudinal adjustment mechanism 42 is shown in an unloaded state of the fitting assembly 10. The projection 56 does not rest on the shoulder 54. Between the components mentioned is a game X1, which simplifies the assembly and adjustment of the fitting assembly 10 in an unloaded condition of the fitting assembly 10. A maximum available assembly game X is made from the above called game X1 and a second game X2 together, which is present in the illustrated state between the projection 56 and a shoulder 54 'of the adjusting shaft 48. In other words, the clearance X is determined by the distance of the shoulders 54, 54 'and the width of the projection 56. The mounting clearance X is in practice between 1 and 10 mm, preferably less than 5 mm, z. B. about 3 mm.

From the foregoing, it can be seen that the adjusting shaft 48 is movable relative to the base part 28 and thus ultimately to the adjusting screw 18. This means that the components 44, 46 of the worm thread must be displaceable relative to each other. In order to ensure that the worm thread can fulfill its function even in the most varied positions of the adjusting shaft 48, i. For example, if X1 = 0 or X2 = 0, the teeth of the gear 46 is made comparatively wide. Even in the above-exemplified extreme situations X1 = 0 or X2 = 0 is still an engagement of the teeth of the gear 46 is ensured in the worm 44 of the adjusting screw 18.

By way of example, the form in which the mounting game X facilitates the mounting of a wing in a frame is explained below. In the following example it is assumed that two fitting arrangements 10 of the type described above are used.

First, the frame members 12 are fixed to the frame and the wing members 14 are fixed to the wing in the approximately correct positions. Then, with the aid of one of the fitting arrangements 10, an adjustment of the position of the wing in the frame is made. Due to the play X, the respective frame parts 12 and wing parts 14 can move freely relative to each other, so that the other fitting arrangement not loaded in this state 10 does not hinder the adjustment. The fitting assembly 10 used in the adjustment carries in this state, the wing alone. Once the wing is properly positioned in the frame, the longitudinal adjustment mechanism 42 of the previously unstressed fitting assembly 10 is actuated until its shoulder 54 abuts the protrusions 56 of the members 28, 30. From then also this fitting assembly 10 provides a supporting effect, without the adjustment itself - ie in the position correction of the wing - to have been used.

Fig. 7 illustrates the geometry of the tab 22, since the carriage 36 is not shown. The carriage 36 ultimately serves as an intermediate element for implementing a rotational movement of the adjusting shaft 48 in a translational movement, which is transmitted to the movable perpendicular thereto by the Querjustierungsmechanismus 50 tab 22.

Fig. 8 shows a section through the fitting assembly 10 in a plane perpendicular to the pivot axis. The fitting assembly 10 is shown in a closed condition of the wing. The fitting assembly 10 is a concealed fitting.

Through the sectional view of Fig. 8 the operation of the adjustable by the adjusting screw 18 'adjustment mechanism becomes clear. By a rotation of the adjusting screw 18 'of the carriage 36 is pivoted in the plane shown. The bearings serve as the grooves 38 and the ribs 40, which - as already described - also serve as guide elements for determining a movement of the carriage 36 parallel to the pivot axis.
