Description

The present invention relates to a corner bearing for a wing of a window, a door or the like with a frame part, which comprises a base plate for attachment to a fixed frame of the window, the door or the like, as well as with a stay and a control arm, each at a End are movably connected to the base plate and at the other end of each movable with the wing of the window, the door or the like can be coupled. In the respective corner bearing of the stay arm and the control arm to form an X-scissors are rotatably coupled together and adjustable between a closed position corresponding to a closed position of the wing, and an open position corresponding to a rotationally open position of the wing.

Such a corner bearing may for example be formed by a fitting arrangement which is arranged concealed between the sash and the fixed frame. In order to avoid a collision of the wing with the fixed frame despite the internal arrangement of the corner bearing when the wing is opened, the wing opening is turned off perpendicular to the main plane of the fixed frame when the wing is opened by the opening arm. In addition to the controlled by the extension arm parking movement of the sash when turning open the wing is a rotary movement of the wing, which is controlled by the control arm. Ausstellarm and control arm are coupled to form the X-scissors in such a way that the simultaneous turning off and turning movement of the wing during turning opening corresponds to a desired trajectory of the wing.
In known fitting arrangements of this kind, the X-scissors formed by the raising and steering arm protrude to a considerable extent into the free space between the wing and the fixed frame in the fully or partially rotationally open position of the wing of the door, window or the like the appearance as well as the accessibility and thus the functionality of the opened window, the door or the like is impaired. A corner bearing with the features of the preamble of claim 1 is in the DE 35 19 988 A1 disclosed.

Furthermore, in known fitting arrangements of this type, one or more sliding and rotary sliding clutches are used to connect the extension arm, control arm and frame part, which are subject to increased wear due to the bearing forces exerted by the weight of the wing and the frictional forces occurring during the sliding movement and the stability of the fitting arrangement decrease. The frictional forces occurring as well as the susceptibility of the sliding and rotary sliding clutches for contamination can also lead to the stiffness of the fitting arrangement.
The EP 0 952 290 A2 discloses a fitting for pivotally attaching a flap to the body of a cabinet. The fitting comprises two intersecting articulated levers.
The object of the invention is to provide an improved corner bearing, which does not affect the appearance and functionality of the window, the door or the like, in particular in drehgeöffem wing of the window, the door or the like and also has an improved wear resistance and stability.

This object is achieved on the basis of a corner bearing of the aforementioned type according to the invention that the extension arm is connected to the base plate via an intermediate link, which is rotatably connected both to the extension arm and to the base plate, wherein the intermediate link is designed and arranged that it protrudes in the opening direction on the base plate neither in the closed position nor in the open position of the extension arm and the control arm.

The intermediate link is in the closed and open position of the raising and control arm behind a frontal plane of the base plate, which is oriented substantially perpendicular to the base plate and limits this in the opening direction.

When turning open the wing moves due to the coupling of the extension arm with the base plate on the intermediate link, the intermediate link associated with the end of the extension arm to the frame-side end of the control arm. In this way, in the open position of the fitting assembly, an approximately closed position of the X-scissors, i. an approximately parallel or obtuse-angled orientation of the extension arm and control arm, achieved, which is why the X-scissors in this position does not or only minimally protrudes into the space between the wing and the fixed frame. Furthermore, since the intermediate link does not protrude into the free space either in the closed position or in the open position of the opening and control arm, this creates a visually appealing fitting arrangement with good accessibility of the opened window or the door or the like.

The intermediate link can be made relatively short in the invention and, for example, over its entire length on the base plate be supported, whereby a stable mounting of the intermediate link and connected to the intermediate link extension arm and thus ultimately the wing is achieved. The corner bearing according to the invention can in principle completely without sliding or rotary slide clutches get along. As a result, wear of the fitting assembly is prevented due to occurring bearing or friction forces.

At the same time, the provided pivot connections, e.g. between the intermediate link and the extension arm, a uniform shut-off and rotary movement of the wing and a uniform torque transmission during the rotary opening achieved, whereby a simple and substantially resistance-free handling of the wing is guaranteed when turning open. A far-reaching and thus expansive movement of the wing when turning open is thereby avoided that the wing performs due to the special coupling on the intermediate link during the rotary opening initially primarily a Abstellbewegung and then mainly a rotational movement. Since just at the beginning of the rotation opening a Abstellbewegung is necessary to avoid collisions, thereby an optimal movement curve of the wing is realized without affecting the space between rotates open wing and fixed frame.

Advantageous embodiments of the invention are described in the subclaims, the description and the drawings.

Preferably, the intermediate link is in any of the opening arm and the control arm during the pivotal opening of the wing occupied, located between the closed position and the open position intermediate position in the opening direction on the base plate out. As a result, a visually appealing fitting arrangement without impairment of the free space arranged between the wing and the fixed frame is achieved in each intermediate position.

The intermediate link is, for example, rotatably coupled to the base plate about a first axis of rotation and rotatably coupled to the extension arm about a second axis of rotation. The first and second axes of rotation are preferably oriented in parallel.
According to an advantageous embodiment, in the closed position of the extension arm and control arm, the first axis of rotation viewed from the opening side of the fitting arrangement ago in front of the second axis of rotation, wherein the first and the second axis of rotation are in succession in particular in the opening direction. In this case, the intermediate link can point to the rear in the direction opposite to the opening direction of the fitting arrangement, so that the opening arm is arranged offset in the closed position in relation to the opening direction to the rear. As a result, a space-saving and compact design of the fitting arrangement is achieved because the control arm can be arranged in front of the rearwardly offset extension arm and can be arranged above the intermediate link and overlapping with the intermediate link.
In the open position of the extension arm and the control arm, the first and the second axis of rotation can lie next to one another in a direction oriented transversely, in particular obliquely or vertically, with respect to the opening direction of the fitting arrangement. As a result, a substantially closed configuration of the X-scissors with correspondingly small space requirement is created in the closed position of raising and control arm.

A further advantageous embodiment of the corner bearing provides that in the closed position of the control arm and the intermediate link at least partially in the direction of the first axis of rotation are arranged one above the other lying. By overlapping in the direction of the first axis of rotation arrangement of control arm and intermediate link a particularly compact design of the fitting arrangement is achieved. In the context of the invention, it is in principle preferred if in each area of the fitting arrangement and in each located between the closed position and the open position Beschlagstellung only a maximum of two elements Ausstellarm, control arm and intermediate link in the direction of the first axis of rotation are arranged one above the other, so that a total of only two-layer X-scissors with correspondingly low height is created.

It is preferred if, in the closed position, the control arm and the extension arm are arranged adjacent to one another in the region of the intermediate link in a direction perpendicular to the first axis of rotation. As a result, a small space requirement for extension arm and control arm in the closed position of the fitting arrangement is created in the direction perpendicular to the first axis of rotation.

In particular, the extension arm and / or the control arm can be designed to be tapered in the region in which the control arm and the extension arm lie next to one another in the closed position. This ensures a particularly low space requirement in the direction perpendicular to the first axis of rotation.

Advantageously, in the closed position of the control arm and the extension arm in the region of the connection between the control arm and the base plate in the direction of the first axis of rotation are arranged one above the other lying. This also ensures a small space requirement of the fitting arrangement.

According to an advantageous embodiment of the invention, the length of the intermediate link is at most half, preferably a maximum of one Third, and more preferably a maximum of a quarter of the length of the stay arm. As a result, an at least approximately complete support of the intermediate link on the base plate in each switching position of the fitting arrangement is made possible and thus increases the stability. At the same time, the space requirement of the fitting arrangement is kept low.
Preferably, the extension arm and the control arm are rotatably and immovably coupled together. As a result, a particularly robust connection between the raising and control arm and an advantageous trajectory of the wing is achieved.
In the context of the invention, the control arm can be coupled or coupled to the wing, for example via a slot in the wing or via a control link rotatably coupled to the control arm and the wing in order to control the rotational position of the wing.

An advantageous embodiment of the corner bearing provides that the control arm has a frame-side end and a wing-side end and is rotatably mounted in the region of the frame-side end via a pivot bearing on the base plate of the frame part about a rotation axis and in the region of the wing-side end with the wing can be coupled and wherein the control arm is supported by two supports on the frame member which receive a force exerted in the region of the coupling between the control arm and the wing by the weight of the wing on the control arm and a force caused by this force in the control arm torque, wherein a support is located closer to the frame-side end of the control arm than the other support, wherein the closer to the frame-side end of the control arm support is formed by a holding device of the frame part, which is independent of the pivot bearing connected to the frame part, which on the control arm engages and at least in a rotational position of the control arm receives a force exerted on the control arm by the weight of the wing force. The fact that the holding device absorbs the force exerted by the weight of the blade force and thereby caused in the control arm torque, the rotational connection between control arm and frame member is relieved, thereby effectively preventing the excessive wear of the pivot bearing and a deflection or a relaxation of the same the stability and wear resistance of the fitting arrangement thus be further increased. Advantageous developments of this embodiment are set forth in the accompanying drawings and the accompanying description. The closer to the frame-side end of the control arm support may be formed as a pure support that does not change or affect the pivotal movement of the control arm or coupled to the fitting wing. Accordingly, a certain pivotal movement of the wing is fixed by the fitting preferably already without the support and the support is preferably adapted to follow the movement of the control arm only.

Another object of the invention comprises a window, a door or the like having a fixed frame, a wing and a corner bearing for the wing, comprising a frame part with a base plate for attachment to the fixed frame, and a stay arm and a control arm, respectively at one end are movably connected to the base plate and at the other end are each movably coupled to the wing, wherein the extension arm and the control arm are rotatably coupled to form an X-scissors and between a closed position, the closed position of the wing corresponds, and an open position, which corresponds to a rotationally open position of the wing, are adjustable. Here is the opening arm connected to the base plate via an intermediate link, which is rotatably connected to both the extension arm and with the base plate, wherein the intermediate link is formed and arranged so that it neither in the closed position nor in the open position of the extension arm and the control arm in the opening direction over the protruding fixed frame.

The corner bearing of the window according to the invention, the door or the like may in particular form a corner bearing according to the invention as described herein. The advantageous embodiments and advantages described herein apply correspondingly to the window according to the invention, the door or the like. The intermediate link may be designed and arranged so that it protrudes in the opening direction over the fixed frame and in particular on the base plate of the fitting arrangement neither in the closed position nor in the open position of the extension arm and the control arm.

The intermediate link is preferably neither in the closed position nor in the open position of the extension arm and control arm in the opening direction on a frontal plane of the fixed frame, which is oriented parallel to the main plane of the frame and limits the fixed frame in the opening direction. Thereby, an attractive appearance and a substantially complete free accessibility of the space between the rotatably opened wing and the fixed frame of the window, the door or the like is ensured.

According to an advantageous embodiment, the wing has a wing rollover, which bears against the fixed frame with the wing closed, wherein the fitting arrangement is arranged with the wing closed, hidden between the wing and the fixed frame.

Fig. 1 and 2 show a corner bearing for a window, a door or the like with a frame part 10, which comprises a base plate 12 for attachment to a fixed frame of the window, the door or the like, and with a stay arm 14 and a control arm 16, each on a frame side End 14a, 16a movable with are connected to the base plate 12 and the other at its other, wing-side end 14b, 16b respectively via a coupling pin 18 movable with a wing of the window, the door or the like can be coupled. The extension arm 14 and the control arm 16 cross each other and are rotatably and immovably connected to form an X-scissors about a rotation axis 19. The control arm 16 is further connected via a pure rotary bearing 20 about a rotation axis 21 rotatably connected to the base plate 12.

The extension arm 14 is connected to the base plate 12 via an intermediate link 22 which is rotatable about the first axis of rotation 24 with the base plate 12 and about a second axis of rotation 26 rotatably connected to the stay 14. The first and second rotation axes 24, 26 are arranged side by side in a direction transverse to the opening direction x. The length of the intermediate link 22 is less than one third of the length of the Ausstellarms 14th

The first axis of rotation 24 of the intermediate link 22 and the axis of rotation 21 of the pivot bearing 20 define a common to the opening direction x substantially perpendicular plane, as well as the axes of the two coupling pin 18 in the in Fig. 3 shown closed position of the fitting assembly.

The intermediate link 22 causes the two of the base plate 12 facing frame-side ends 14a, 16a of Ausstellarms 14 on the one hand and the control arm 16 on the other hand to move towards each other during the rotational opening of the fitting assembly. The X-scissors formed by the extension arm 14 and the control arm 16 therefore assumes an almost completely closed configuration in the open position of the extension arm 14 and control arm 16, in which the extension arm 14 and the control arm 16 are oriented at least approximately parallel or at an obtuse angle to each other. The intermediate link 22 is neither in the closed position ( Fig. 3 ) still in an intermediate position or in the fully rotationally open position, in which the wing may have a rotational angle relative to the fixed frame of at least approximately or slightly more than 90 degrees, in the opening direction x on the base plate 12. In this way, the space requirement of the X-scissors within the space between the wing and the fixed frame in the fully or partially rotationally open position of the wing is minimized.

Starting from the in Fig. 3 shown closed position during the rotation opening of the fitting initially a pronounced Abstellbewegung of the wing in the x direction by rotation of the extension arm 14 about the second axis of rotation 26. With increasing rotation opening the movement of the wing is in a major rotational movement. The pronounced Abstellbewegung at the beginning of the rotary opening compared to the end of the rotary opening causes an ideal shutdown and collision avoidance without an unnecessarily sweeping wing movement.

Fig. 3 shows the fitting arrangement of Fig. 1 and 2 in the closed position of the Ausstellarms 14 and the control arm 16, in which a wing coupled to the fitting arrangement occupies a rotational angle of about 0 degrees relative to the main plane of the fixed frame. In this position, the first and the second rotational axis 24, 26 of the intermediate link 22 are arranged in a line parallel to the opening direction x, wherein the first axis of rotation 24 is located in front of the second axis of rotation 26 viewed from the opening side. As in Fig. 3 shown, the control arm 16 and the intermediate link 22 are arranged in this position in the vertical direction z overlapping one above the other. The extension arm 14 is arranged in the region of the intermediate link 22 next to the control arm 16. In the region of the coupling between the control arm 16 and the base plate 12, the extension arm 14 and the control arm 16 are arranged overlapping one another in the direction z. For this purpose, the extension arm 14 and the control arm 16 each have an offset between their two ends 14a, 14b, 16a, 16b.

The fact that in each Beschlagstellung anywhere at most two of the elements Ausstellarm 14, control arm 16 and intermediate link 22 are arranged one above the other in the z direction, results in an extremely compact, since only two-layered design of the fitting assembly in the z-direction. Due to the entangled arrangement of intermediate link 22, extension arm 14 and control arm 16, the fitting also perpendicular to an extremely compact design.

In the Fig. 1 to 3 shown fitting assembly further includes a holding device 28 which is connected independently of the pivot bearing 20 with the frame member 10 which engages the control arm 16 and the 16 in each rotational position of the control arm 16 on the control arm 16 by the weight of the wing at its wing-side end exerts applied force and thus forms a first closer to the frame-side end 16a of the control arm 16 support for the control arm 16. The holding device 28 acts on the upper side 30 of the control arm 16 and, in particular with the wing open, assumes a force of the control arm 16 oriented in the positive z-direction. For this purpose, the holding device 28 forms an effective in the positive z-direction undercut with the control arm 16. The trajectory of the wing is not additionally limited by the holder 28, since the holding device 28 is coupled only via the control arm 16 with the wing. The holding device 28 thus serves exclusively to accommodate the weight of the wing and their introduction of force into the frame part 10th

A second, further away from the frame-side end 16a of the control arm 16 support of the control arm 16 is formed by the fact that the control arm 16 abuts in the region of the front edge 34 of the base plate 12 with its underside 32 on the base plate 12. By this system, an oriented in the negative z-direction force of the control arm 16 is added. The two supports formed by the holding device 28 and the base plate 12 cause a recording of the force acting on the control arm 16 in the region of its front, wing-side end 16b weight of the wing and the resulting in the control arm 16 torque. The holding device 28 relieves in this way the pivot bearing 20 with which the control arm 16 is rotatably mounted on the base plate 12, from the force exerted by the weight of the wing on the control arm 16 force, so that the pivot bearing 20 substantially only in the horizontal Level perpendicular to the axis of rotation 21 acting rotational forces must absorb. As a result, an excessive wear and in particular a deflection or a loosening of the pivot bearing 20 is effectively prevented, and thus the overall wear resistance of the fitting arrangement is considerably increased.

The holding device 28 engages in a region 36 of the control arm 16 on the control arm 16, which is located farther away from the wing-side end 16 b of the control arm 16 as the rotational axis 21 of the pivot bearing 20. This is a particularly good leverage of the holding device 28 and thus a causes particularly effective absorption of the weight exerted by the wing on the control arm 16 weight.

The area 36 of the control arm 16 is in the closed position of the control arm 16 from the opening side of the fitting arrangement forth behind the rotation axis 21. In this way, a space-saving arrangement of the holding device 28 is achieved and obstructing the movement of the control arm 16 and the wing avoided.

The holding device 28 comprises a beam element elongate in the z-direction, coupled to the control arm 16 and a holding element 38 in the z-direction also elongated in the z-direction bar-shaped connecting element 40. The holding member 38 and the connecting member 40 are rotatable about a rotation axis 42 with each other and each about a rotational axis 44, 46 rotatably connected to the control arm 16 and an extension 48 of a perpendicular to the base plate 12 arranged leg 50 of the Eckwinkelförmigen frame member 10 and form a V-scissors. As a result of this design of the holding device 28 as a V-type scissors, in spite of the eccentric arrangement of the coupling region 36 with respect to the axis of rotation 21 of the control arm 16, there is a shift between the holding device 28 and the control arm 16 in any position of the control arm 16 without shifting and based on a pure rotational movement reached. Such a purely rotating coupling effects a particularly effective, reliable and low-wear introduction of force from the control arm 16 via the holding device 28 into the frame part 10. In principle, however, instead of a displacement-free rotary connection, a sliding or rolling coupling between the holding device 28 or the holding element 38 and the control arm 16 is possible. Accordingly, the holding device 28 may in principle also be formed in one piece and in particular rigid. Likewise, the holding device 28 may be rotatably or rigidly connected to the frame part 10 and in particular also be formed simply by a projection of the frame part 10, which is slidably coupled to the control arm 16.

The V-scissors is in the closed position of the control arm 16 as in Fig. 3 shown substantially closed, ie has an opening angle of approximately 0 degrees, while in the in Fig. 1 and 2 shown intermediate position has an opening angle of greater than 90 degrees and in the not fully illustrated fully rotationally open position has an opening angle of approximately 180 degrees. As a result, a particularly small-sized and thus stable and space-saving holding device 28 is achieved.

In the areas of the coupling between the control arm 16 and the holding element 38 (area 36) and between the holding element 38 and the connecting element 40 and between the connecting element 40 and the frame part 10, the respective elements abut each other on bearing surfaces, which are smaller than the respective base surfaces of the control arm 16, the retaining element 38 and the connecting element 40. As a result, the friction occurring during the movement of the holding device 28 is reduced. The bearing surfaces are defined by corresponding, protruding in the z-direction projections 52 between the control arm 16, the support member 38 and the connecting member 40.

The base plate 12 is provided in the region of the X-scissors formed by the stay arm 14, the control arm 16 and the intermediate link 22 with an additional coating or an additional sheet 53, which engages over the front edge 34 of the base plate 12 with a particular rounded bend. As a result, a sliding surface is provided which reduces the friction between the control arm 16 and the intermediate link 22 and the base plate 12 upon actuation of the fitting arrangement. Control arm 16 and intermediate link 22 slide on the Sheet 53 and the coating, wherein the control arm 16 is also supported in the region of the front edge 34 of the base plate 12 through this downwards. The bending / rounding of the front edge 34 formed by the sheet 53 or the coating additionally serves to reduce the friction or shear between the control arm 16 and the base plate 12 in the region of the front edge 34.

Fig. 4 shows a perspective view of a corner bearing according to another embodiment of the invention in a partially rotationally open position. The fitting arrangement of Fig. 4 does not have any like in Fig. 1 to 3 shown holding device 28 and otherwise corresponds to the in Fig. 1 to 3 shown embodiment.

Fig. 5 shows another corner bearing in the closed position, which is essentially the in Fig. 1 to 3 shown fitting arrangement corresponds. At the in Fig. 5 However, shown fitting arrangement, the V-scissors formed by the holding member 38 and the connecting member 40 is arranged so that its open side, at least in the illustrated closed position and / or at least partially open wing toward the interior of the room. This means that the mean direction or vector sum from the direction oriented from the rotation axis 42 to the rotation axis 44 and the direction oriented from the rotation axis 42 to the rotation axis 46 has a directional component pointing in the positive opening direction x. The axis of rotation 42 is accordingly further away from the axis of rotation 21 of the pivot bearing 20 than the axis of rotation 46. Similar to the representation of FIG Fig. 3 can in the closed position, the holding element 38 and the connecting element 40 - in deviation from the illustration according to Fig. 5 - Be aligned at least approximately parallel to each other. Contrary to the execution after Fig. 3 is the common axis of rotation 42 while the stationary axis of rotation 44 for Spaces outward. Compared to the in Fig. 1 to 3 In the embodiment shown in which the open side of the V-scissors points in the direction of the exterior, improved space utilization is achieved because more space is available in the opening direction x for the control arm 16, the extension arm 14 and the wing.

    the control arm (16) has a frame-side end (16a) and a leaf-side end (16b) and is rotatably supported about an axis of rotation (21) at the base plate (12) of the frame part (10) via a rotary bearing (20) in the region of the frame-side end (16a) and is couplable to the leaf in the region of the leaf-side end (16b), with the control arm (16) being supported at the frame part (10) by two supports which take up a force exerted onto the control arm (16) by the weight of the leaf in the region of the coupling between the control arm (16) and the leaf and which take up a torque produced in the control arm (16) by this force, with one support being disposed closer to the frame-side end (16a) of the control arm (16) than the other support, and with the support disposed closer to the frame-side end (16a) of the control arm (16) being formed by a holding apparatus (28) of the frame part (10) which is connected to the frame part (10) independently of the rotary bearing (20), which engages at the control arm (16) and which takes up a force exerted onto the control arm (16) by the weight of the leaf in at least one rotational position of the control arm (16).
13. A window, a door or the like having a fixed-position frame, having a leaf and having a corner bearing for the leaf, which corner bearing comprises a frame part (10), having a base plate (12) for attachment to the fixed-position frame, as well as an opening arm (14) and a control arm (16) which are each movably connected to the base plate (12) at one end (14a, 16a) and which are each movably coupled to the leaf at their other end (14b, 16b), wherein the opening arm (14) and the control arm (16) are rotatably coupled to one another to form an X scissor stay and are adjustable between a closed position which corresponds to a closed position of the leaf and an open position which corresponds to a turned-open position of the leaf, characterized in that
    the opening arm (14) is connected to the base plate (12) via an intermediate guide (22) which is rotatably connected both to the opening arm (14) and to the base plate (12), with the intermediate guide (22) being configured and arranged such that it does not project beyond the fixed-position frame in the opening direction (x) either in the closed position or in the open position of the opening arm (14) and of the control arm (16).
14. A window, a door or the like in accordance with claim 13, characterized in that
    the leaf has a leaf overlap which contacts the fixed-position frame when the leaf is closed; and in that the fitting arrangement is arranged concealed between the leaf and the fixed-position frame when the leaf is closed.
15. A window, a door or the like in accordance with claim 13 or claim 14,
    characterized in that
    the control arm (16) is coupled to the leaf via an elongate hole of the leaf or via a control guide which is respectively rotatably coupled to the control arm (16) and to the leaf.
