Description

Corner bearing for a concealed fitting with an improved turning curve and arrangement with such a corner bearing

Background of the invention

The invention relates to a corner bearing for a fitting for a door or a window, with a base plate, a corner hinge with a horizontal component, a control bracket, a control guide, a support bracket and a link guide in the corner hinge, the corner hinge being rotatable via a first connection point on the Control tab and rotatably arranged on the support bracket via a second connection point and the control bracket is rotatably arranged on the base plate and on the support bracket. The support bracket is rotatably arranged on the base plate and on the control bracket. The horizontal component has a main direction of extent, the link guide in the corner hinge and a vertical central plane which is formed in the main direction of extent of the horizontal component and perpendicular to the horizontal component. The invention also relates to an arrangement with such a corner bearing. Such corner bearings, in particular for the area of concealed fittings, are already known from the prior art. In conjunction with the control and link guides, the control and support tabs form a scissor mechanism which enables a sash arranged on the fitting to be lifted off the frame and then pivoted. This opening sequence prevents the sash from colliding with the wall surrounding the frame and enables opening. The fitting and a wing arranged thereon move along a movement curve predetermined by the scissor mechanism.

Such a fitting is known, for example, from CN 201981911 U and DE 102 05 009 C2.

The known fittings here, however, have an overshooting behavior or an overshooting movement curve, which is associated with an increased space requirement in the transverse direction of the window. Overshoot is understood to mean a space requirement of the fitting in the transverse direction of the window when opening and / or closing, which is higher than the space requirement of the fitting in the transverse direction of the window in the fully open state. In the area of application of sashes with concealed hardware, overshooting of the hardware can lead to a collision of the sash frame with the wall. Therefore, with conventional fittings, an opening area must be provided on the fastening side of the fitting on the frame. If the fitting is used in the area of windows and doors, this leads to an undesirably wide gap (shadow gap) between the wall and the door or window sash.

This leads in an unfavorable way to a reduction in the maximum possible window or door width or the opening released by the sash with the installation space remaining the same or, in the opposite sense, to a larger installation space required for the sash. Object of the invention

It is the object of the invention to provide a fitting with an improved overshoot behavior which is robust and inexpensive to manufacture at the same time. It is a further object of the invention to provide an arrangement with such a fitting.

Description of the invention

These objects are achieved by a fitting according to claim 1 and an arrangement according to claim 12. The subclaims reproduce preferred developments.

The objects are thus achieved in an astonishingly simple way by a fitting of the type mentioned at the outset, which is characterized in that the link guide in the corner hinge has a link center track which, in at least one section, in particular in several subsections, particularly preferably in all subsections, in addition to the vertical center plane of the horizontal component is formed. An at least section-wise displacement of the link center path of the link guide next to the center plane of the horizontal component enables, in a particularly simple manner, an at least section-wise change in the movement curve when opening and closing the corner bearing. In particular, at least a partial section of the link center path has a distance between 0.1 and 10 millimeters, particularly preferably between 0.5 and 3 millimeters, from the center plane. The slide center track preferably has a distance of between 0.1 and 10 millimeters or between 0.5 and 3 millimeters from the center plane by more than 50%, in particular more than 70%, particularly preferably more than 80%.

The center track can be straight, angled or curved. The center track can run offset to the center plane or cross the center plane. The slide center track preferably runs next to the center plane, except for the points of intersection with the center plane.

In a preferred embodiment, the invention is characterized in that the first connection point and the second connection point in at least one subsection, in particular in several subsections, particularly preferably in all subsections, of the link guide form a straight connecting line which is at an angle (of more than 0 °, in particular by more than 1 °) is inclined to the central plane of the corner hinge.

The terms “vertical” and “horizontal” relate to the conventional installation orientation of a fitting on a bottom and / or top of a door and / or a window. A vertical is therefore formed in or against the direction of gravity and a horizontal in a direction orthogonal to the vertical. The term “rotatable” is understood below to mean both a movement around a fixed pivot point and a movement around a movable pivot point. Thus, the term “rotatable” also relates to the rotary part of a movement superimposed by a translational part.

The corner band can be formed in one piece or in several pieces.

The corner hinge has a horizontal component, in particular in the form of a bar, with a central plane. The horizontal component has a longitudinal extension and a transverse extension. The central plane relates to the center of the transverse extent or the geometric extent of the horizontal component transversely, in particular at right angles, to the longitudinal extent of the main direction of extent of the horizontal component.

The corner hinge has a first connection point via which the corner hinge is arranged directly or indirectly on the control bracket. For this purpose, the horizontal component can have a recess. However, it is also conceivable that the first connection point, in particular in the form of a sleeve, on the corner hinge is arranged. In particular, the first connection point is formed or arranged at one end of the horizontal component and has a vertical recess, in particular a through recess, for the arrangement of a connecting means, in particular a bolt.

In addition, the first connection point can have a vertical adjustment, in particular in the form of a screw-in sleeve, with which the penetration depth of a connecting means, in particular a bolt, is limited. This allows the vertical position of the corner hinge to be set in relation to the support bracket and the base plate in a particularly advantageous manner.

The horizontal component has the link guide. The backdrop can in particular be formed or framed by several components of the horizontal component and / or by a recess in the horizontal component. With regard to its dimensions, the link guide extends predominantly, in particular completely, in the longitudinal direction of the horizontal component and in particular has a length between 10 and 100 millimeters, particularly preferably between 20 and 60 millimeters.

The link guide has the second connection point of the corner hinge, via which the corner hinge is arranged on the support bracket. The second connection point is preferably designed in the form of a vertically extending nozzle. The area of the second connection point, in particular of the connecting piece, which is arranged in the interior of the link guide, preferably has a diameter with the dimensions of the guide width of the link guide. The link guide enables a translational relative movement between the corner hinge and the second connection point and a superimposed translational and rotational relative movement between the corner hinge and the support bracket. The second connection point is forcibly guided horizontally and / or vertically in the predominant, in particular the entire, part of the slide extension in the slide along its slide center path and moves depending on the opening angle of the fitting from one end of the slide guide to the other end. The respective ends of the link guide can act as a stop, or to limit the movement of the second connection point.

In particular, by forming a connecting straight line between the first connection point and the second connection point, which is inclined at an angle to the central plane, the relative position of the corner hinge to the support bracket and thus the relative position of the corner hinge to the rest of the fitting can be at least in an opening area of the fitting that is decisive for a Overshoot of the fitting is responsible to be changed in such a way that overshoot is reduced or partially or completely prevented. In other words, the relative position of the corner hinge can be adapted as a function of the opening angle of the fitting. For example, overshooting of the entire fitting can be prevented by compensating for overshooting of the control and support bracket by changing the position of the corner hinge relative to the control and support bracket.

In particular, the angle between the connecting straight line and the central plane is formed against an opening direction of the fitting. In other words, the straight connecting line follows the opening angle of the fitting.

The corner hinge is preferably arranged on the control and / or support bracket via the first and / or second connection point by means of a bolt or socket connection. A bolt or socket connection is an inexpensive and effective way of forming a rotatable connection between the components. However, all types of connection, such as screw, rivet, plug-in and clamp connections, which enable a rotatable arrangement, are also conceivable. The list is not to be understood as exhaustive.

It is also conceivable to form the connection in one piece and / or in several pieces with the support and / or control tab. In order to enable simple assembly and dismantling of the corner hinge, in particular when the sash is arranged thereon, the corner hinge in particular is arranged detachably on the control and / or support bracket.

A further development of the corner bearing is particularly preferred in which the link guide in the corner hinge has a horizontally curved link center path. A curved center track enables a particularly flexible change in the angle of the connecting straight line in relation to the angle to the center plane. In addition, by curvature of the center track, the course of the center track is changed continuously or without jerks, and a particularly uniform opening of the fitting is achieved.

Also preferred is an embodiment of the corner bearing in which the horizontal component has one, in particular two, projections arranged laterally on the horizontal component and extending in the longitudinal direction of the horizontal component. The projections can form a vertical stop surface opposite a sash to be arranged of a window and / or a door. As a result, a vertical arrangement of the corner hinge on a sash of a window and / or a door can take place particularly easily.

In a particularly preferred embodiment of the corner bearing, the slide center track of the slide guide in the corner hinge crosses the vertical center plane at least once, in particular at least twice. In other words, the slide center track runs in the horizontal component in such a way that it changes at least once from one side of the center plane to the other side of the center plane, ie in the direction of the transverse extent of the horizontal component from a geometric edge transversely to the main direction of extent of the horizontal component opposite edge runs. As a result, the available transverse extent, or the width of the horizontal component, is used particularly effectively. In particular, when the central plane is crossed at least twice, particularly good utilization of the transverse extent of the horizontal component can be achieved. In connection with a constant curvature of the backdrop, a special uniform course of the opening curve of the fitting can be achieved with the least possible overshoot of the fitting.

Also preferred is an embodiment of the corner bearing in which the first connection point has an axis of rotation that is parallel to the vertical center plane. In other words, the axis of rotation of the first connection point does not intersect the vertical center plane. The axis of rotation is in particular at a distance between 0.5 and 10 millimeters, particularly preferably between 2 and 4 millimeters, from the central plane. This enables an angle to be formed between the straight connecting line and the central plane in a particularly simple manner.

Preferably, at least a partial section of the link center path is formed on the side of the center plane of the horizontal component opposite the side having the axis of rotation. In particular, the portion of a distance that is orthogonal to the center plane to a partial section of the center track is at least 3 to 10 millimeters, particularly preferably 4 to 8 millimeters.

An embodiment of the corner bearing is particularly preferred in which the link guide in the corner hinge has at least one, in particular two, vertical stop surfaces in an at least predominant part of the link guide. The corner hinge can be arranged on the support bracket particularly advantageously if the connection, in particular the connecting piece, forms one, in particular two, preferably one vertical stop surface running around the connecting piece, which is configured opposite to the at least one stop surface of the link guide. In other words, the connection, in particular the connecting piece, engages behind part of the link guide in the vertical direction, so that a vertical lifting of the corner hinge from the support bracket within the link is prevented.

Furthermore, an embodiment of the corner bearing is preferred in which the link guide in the corner hinge in at least one section, in particular in an end section, the link guide has an entry and exit area for the second connection point. An infeed and outfeed area has an advantageous effect on the arrangement of the corner hinge on the control and support bracket, since it favors threading in and / or out of the second connection point, in particular the socket. Particularly preferably, it can be provided that the stop surfaces of the link projections are vertically curved in the immediate area in front of the entry and exit area and encourage the second connection point to be threaded in and / or out. In this way, the arrangement of the corner band on the carrying strap can be made possible in a particularly simple manner.

Particularly advantageously, the link guide has the entry and exit area for the second connection point in the section in which the second connection point, in particular the connecting piece, is located at an almost closed opening angle of the fitting. As a result, the corner bearing can be prevented from being threaded out in an open state of the fitting, in particular of the sash, in a safety-relevant manner.

The link guide also advantageously has a constant guide width over the major part, in particular over the entire part, of its extension. The guide width relates to the side walls of the link guide, along which the second connection point is guided. In particular, the stop surfaces at the ends of the side walls of the link guide have a complementary shape to the formation of the guided second connection point. For example, the stop surfaces are designed in the form of a semicircle if the second connection point is designed in the form of a round connector.

An embodiment of the corner bearing is particularly preferred in which the control guide is designed in the base plate, in particular in the form of a link guide. In this way, a reduction in the structural strength of the control tab can be minimized by a recess. In a preferred development of the corner bearing, a cover plate for covering the control guide is arranged between the base plate and the control bracket. A cover plate effectively prevents contamination of the control guide, which has a particularly favorable effect on the functionality, service life and maintenance intervals of the fitting.

A preferred embodiment of the corner bearing provides that the base plate has a base. The fitting can be adapted particularly easily to existing installation conditions, in particular the frame, by means of a base. The base can be formed in one piece or in several pieces. The base can be made of metal and / or plastic. In addition, the base can have lateral recesses and / or projections, by means of which the base can be designed to be arranged particularly easily on the frame.

Also preferred is an embodiment of the corner bearing in which the corner hinge has a vertical component, in particular in the form of a bolt. The vertical component has a vertical longitudinal extension. The vertical component can have the first connection point. In addition, it can be provided that the vertical component is arranged on the horizontal component, in particular orthogonally. In this case, the first connection point can be arranged on the horizontal and / or the vertical component of the corner band.

More preferably, the vertical component can have one, in particular two, lateral projections which extend in the direction of the vertical longitudinal extension of the vertical component. The projections can form a horizontal stop surface opposite a sash to be arranged of a window and / or a door. As a result, a horizontal arrangement of the corner hinge on a sash of a window and / or a door can take place particularly easily. In a preferred embodiment of the corner bearing, the straight connecting line has an angle between 1 ° to 30 °, in particular between 1 ° to 20 °, particularly preferably between 1 ° to 10 °, in at least one opening angle, in particular several opening angles, particularly preferably all opening angles, of the fitting , to the center plane of the horizontal component.

An embodiment of the corner bearing with exactly one control bracket and exactly one support bracket is also preferred.

The corner bearing is preferably designed for arrangement in the rebate space, in particular in a corner area of the rebate space, between the sash and the frame.

arrangement

The object underlying the invention is also achieved by an arrangement with a corner bearing according to the invention, with a sash for a window or door and a frame, the base plate of the corner bearing being arranged on the frame and the corner hinge of the corner bearing on the sash.

The corner bearing is preferably arranged in the rebate area, in particular in a corner area of the rebate area, between the sash and the frame.

Further advantages of the invention emerge from the description and the drawing. The features mentioned above and below can also be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for describing the invention.

Fig. 10 shows a plan view of the second embodiment of the corner bearing in the pivoted-in state.

Fig. 1 shows an arrangement 10 with a corner bearing 12, a fixed frame 14 in the form of a window frame and a wing 16 in the form of a window sash. The arrangement 10 is arranged in a recess in a wall 18. The corner bearing 12 is designed as part of a concealed fitting and has a base plate 20, a support bracket 22, a control bracket 24 and a corner hinge 26. The arrangement 10 is in a partially open state. The corner bearing 12 is arranged in a corner region of the rebate space between the wing 16 and the fixed frame 14.

FIG. 2 shows the arrangement 10 from FIG. 1 in a closed state. The corner bearing 12 is concealed between the frame 14 and the wing 16 and is therefore not visible from the outside. The wing 16 ends in a plane parallel to the wall 18. The wing 16 has on its vertical side 28 closest to the corner bearing 12 a function-related gap 30 in the form of a shadow gap. The function-related gap 30 is used when pivoting the corner bearing 12 to screw in the sash 16, in particular the sash frame. The pivoting of the corner bearing 12 includes a moving movement of the sash 16 from the frame 14 and a rotary movement of the sash 16 about an axis of rotation 32 (directed into and out of the plane of the drawing) of a first connection point 34 of the corner hinge 26. The shutdown movement and the rotary movement are superimposed.

A movement curve 36 of the wing 16 illustrates the movement of a maximally pivoting point 38. In this case, the maximally pivoting point 38 is to be understood as a point on the front of the wing 16 which is at a maximum distance from the rotational axis 32 of the first connection point 34 and at Opening the wing 16 is rotated into the functional gap 30.

The course of the movement curve 36 approaches a maximum deflection plane 40 running orthogonally to the wall 18. There is no overshoot due to the maximum pivoting point 38. As a result, the function-related gap 30 can advantageously be made particularly narrow.

FIG. 3 shows the arrangement 10 from FIG. 1 in a partially open state of the window. The pivoting point 38 of the wing 16 has moved along the movement curve 36 into a central position on the movement curve 36. FIG. 4 shows the arrangement 10 from FIG. 1 in an open state. The pivoting point 38 of the wing 16 has moved along the movement curve 36 to an end position of the movement curve 36. The wing 16 is in a maximally open state, the corner bearing 12 is therefore completely swiveled out.

FIG. 5 illustrates in a perspective view the corner bearing 12 of the arrangement 10 from FIGS. 1-4. The corner hinge 26 has a horizontal component 42 and a vertical component 44. The vertical component 44 is arranged at right angles to the horizontal component 42. Both the vertical component 44 and the horizontal component 42 form projections 46 which serve as stop surfaces when a wing 16 is arranged (see FIGS. 1-4). As a result, the position of the corner hinge 12 on the wing 16 can be determined via the stop surfaces and the arrangement is particularly simple.

The vertical component 44 has the first connection point 34 for the rotatable arrangement of the corner hinge 12 on the control bracket 24. In the exemplary embodiment described, the first connection point 34 is arranged in a non-detachable manner on the vertical component 44 and is designed in the form of a sleeve. Alternatively, the connection point can be designed to be detachable. The first connection point 34 is positioned on the control bracket 24 by means of a bolt 148 (see FIG. 9) or connecting piece, in particular a push-through bolt. The bolt 148 is arranged immovably on the control bracket 24, while the corner hinge 12 continues to rotate about the axis of the bolt 148 or about the axis of rotation 32 (see FIG. 2).

The horizontal component 42 has a link guide 50 in which a second connection point 52 in the form of a connector, in particular in the form of an offset connector, is positively guided. The second connection point 52 engages behind in the vertical direction at one end two link projections 54 projecting horizontally into the link guide 50 and is arranged on the support bracket 22 at the other end via a riveted connection. In the case of using an eccentric With the offset connection, a fine adjustment of the position of the second connection point 52 and the associated position of the corner hinge 26 can be carried out particularly advantageously. The link projections 54 can be connected to one another.

6 shows a top view of the corner bearing 12 from FIG. 5 in a right-angled swiveled-out state and illustrates the course of the second connection point 52 during the forced guidance through the link guide 50 when the corner bearing 12 is pivoted out. The horizontal component 42 has a center plane 56 in relation to it on their direction of extent transversely to the main direction of extent. In other words, the center plane 56 halves the width of the horizontal component 42. The link guide 50 has a link center path 58 with a curved course. A deflection of the link center track 58 from the center plane 56 changes the relative position of the corner hinge 26 (and thus the relative position of a wing 16 arranged on the corner hinge 26) to the rest of the corner bearing 12 and enables an at least partial change in the movement curve 36 (see Fig. 2) when the Corner bearing 12.

During the pivoting of the corner bearing 12, the second connection point 52 within the link guide 50 is moved towards the first connection point 34 and thereby crosses the center plane 56 of the horizontal component 42. A straight line 60 between the first connection point 34 and the second connection point 52 forms with the center plane 56 an angle 62, which increases with increasing pivoting movement. In other words, the corner hinge 26 is increasingly moved into a position that precedes the pivoting movement during the pivoting process. The degree of the change in angle is determined by the course of the link center path 58 relative to the first connection point 34.

If the scissors mechanism (base plate 20, support bracket 22 and control bracket 24) of the corner bearing 12 is deployed without a straight connecting line 60 inclined to the central plane 56, when the sash 16 is arranged, the sash 16 overshoots in the function-related gap 30 (see FIG. 2). By changing the At the angle of inclination 62 while the scissor mechanism is deployed, the relative position of the corner hinge 26 (and the wing 16 arranged on the corner hinge 26) to the scissor mechanism can be changed and overshooting of the wing 16 in the function-related gap 30 can be reduced, in particular avoided.

The first connection point 34 has the axis of rotation 32 (directed into or out of the plane of the drawing), which is formed parallel to the central plane 56. In other words, the axis of rotation 32 is designed to be decentered relative to the central plane 56. By increasing the distance between the axis of rotation 32 and the central plane 56, the angle 62, together with the course of the central track 58, can be set in a particularly large angular range. This enables a particularly flexible adaptation of the movement curve 36 (see FIG. 2).

FIG. 7 shows the first embodiment of the corner bearing 12 from FIGS. 1-6 in a view from below, but without corner hinge 26 (see Fig. 1-6). The base plate 20 has a control guide 64 in the form of a curved link guide. In the control guide 64, a control connector 66 is forcibly guided, which arranges the control tab 24 on the base plate 20. The control guide 64 is covered on the top by a cover plate 68. The cover plate 68 serves as a spacer between the base plate 20 and the control bracket 24 and ensures the freedom of movement of the support bracket 22. By arranging the cover plate 68 on the control bracket 24, the control guide 64 is also covered in the entire pivoting area of the corner bearing 12 and soiling is prevented.

The base plate 20 has two positioning bolts 70 or positioning stubs which are designed to allow the corner bearing 12 to be arranged on a frame 14 (see FIGS. 1-4) in a particularly simple manner.

Fig. 8 shows a plan view of the corner bearing 12 in the pivoted-in state. From Fig. 8 it can be seen that the center of the link guide 50 in sections is formed horizontally offset to the central plane 56. In the present case, the center of the link guide 50 is designed to be horizontally offset from the center plane 56 to more than 80% of its longitudinal extent.

FIG. 9 shows a second embodiment of a corner bearing 112 with a base plate 120, a support bracket 122 and a control bracket 124 in a partially pivoted-out state.

According to the second embodiment of the corner bearing 112, the control tab 124 has a control guide 164. As a result, a control guide 64 (see FIG. 7) in the base plate 120 can be dispensed with.

Fig. 10 shows a plan view of the second embodiment of the corner bearing 112 in the pivoted-in state. A first connection point 134 and a second connection point 152 form a straight connecting line 160. The straight connecting line 160 is inclined at an angle 162 to the center plane 156 of a corner hinge 126. A link center track 158 of a link guide 150 is formed parallel to the center plane 156. This enables a uniform change in the angle of the angle 162 when the corner bearing 126 is pivoted in and out.

The link guide 150 has link projections 154 which extend parallel to the link center track 158 over a large part of the link guide 150. The link projections 154 can be connected to one another. At one end of the link guide 150 there is an entry and exit area 172 without link projections 154, which enables the second connection point 152 to be introduced and exited into the corner hinge 126 (analogous to this, an entry and exit area 72 is provided in the first embodiment [see FIG. 6]). intended). In order to prevent undesired unthreading of the second connection point 152 when the corner bearing 112 is at least partially pivoted out, the second connection point 152 is only in the pivoted-in state of the corner bearing 112 in the entry and exit area 172 second connection point 152 in the vertical direction effectively lifting the corner band 126.

Taking all the figures of the drawing together, the invention relates to a corner bearing 12, 112 for a door and / or window fitting with a base plate 20, 120, a support bracket 22, 122, a control bracket 24, 124 and a corner hinge 26, 126, which are arranged on one another by means of a scissor mechanism and the corner hinge 26, 126 in particular a

Connecting straight lines 60, 160 between a first connection point 34, 134 and a second connection point 52, 152, which at at least one opening angle of the corner bearing 12, 112 at an angle 62, 162 to a vertical plane 56, 156 longitudinally centered of the horizontal component 42 of the corner hinge 26, 126 is inclined. The axis of rotation 32 of the first connection point 34, 134 is preferably formed outside the vertically extending center plane 56, 156 of the horizontal component 42. As an alternative or in addition to this, a link guide 50, 150 is preferably formed predominantly outside of this central plane 56, 156.
