Description

The present invention relates to a corner fitting according to the preamble of claim 1 and a method for arranging a door element on a pivot point and/or an axis according to the preamble of claim 10.

It is known to provide door elements, in particular glass doors, such as glass swing doors or glass sliding doors, with fittings or fitting devices. The fitting devices usually consist of two fitting elements between which the door element or the glass door is clamped. In addition to the clamping, the door elements are optionally held by fastening means in accordance with specified standards, which are guided through the fitting devices and through recesses, for example bores in the door element. In order to clamp the door elements between the fitting elements, a cutout is cut out in the corner areas of the door elements along their contour. The fitting elements are placed on the contour of the door element and form a free space in the area of the cutout of the door element, in which, via a connecting element, which is part of the fitting device and which is preferably arranged between the fitting elements, the door element is pivoted and/or an axis can be arranged or mounted.

A disadvantage of the corner fittings known on the market is that they only have a rigid connecting element, ie a connecting element that is fixed in its position. In particular disadvantageous that the known corner fittings can only be chosen for two fixed pivot points or axes, namely for 55 mm and 65 mm. It is therefore not possible with the known corner fittings to adapt them to pivot points or axes that do not correspond to the specification of 55 mm and 65 mm. This has the particular disadvantage that swing doors, for example, cannot be adjusted to the dimension of these pivot points or axes on pivot points or axes that correspond to the specification of 55 mm and 65 mm. It is therefore not possible with the known corner fittings, for example, to align a swing door 100% flush on a non-standard pivot point or axis.

the DE8536840U discloses a generic corner fitting.

It is the object of the present invention to at least partially eliminate the disadvantages of the prior art described above. In particular, it is the object of the present invention to provide a corner fitting for door elements that also allows the door element to be aligned outside of the standard, in particular outside of pivot points and/or axes with e.g. 55 mm and e.g. 65 mm.

The above object is achieved by a corner fitting with the features of claim 1 and by a method with the features of claim 10. Further advantages, features and details of the invention result from the dependent claims, the description and the drawings. Features and details that are described in connection with the corner fitting according to the invention naturally also apply in connection with the method according to the invention and vice versa, so that the disclosure of the individual aspects of the invention is or can always be referred to reciprocally.

The corner fitting according to the invention for a door element that can be arranged on a pivot point and/or an axis, having a first fitting element and a second fitting element, which each have at least regionally a contact section for contact with the door element and can be connected to one another while the door element is clamped, closes the technical Teaching that a clamping area is formed between the two fitting elements, into which the door element can be inserted, and the fitting elements are designed in such a way that a holding element is arranged between the two fitting elements, which is displaceable relative to the fitting elements and is connected to at least one fitting element by force - And/or can be connected in a form-fitting manner, the retaining element being in operative connection with a connecting element which is used to support the door element on the pivot point and/or the axis.

This solution offers the advantage that with the retaining element that is displaceable relative to the fitting element, the connecting element that is operatively connected to the retaining element can be displaced. Accordingly, by moving the holding element relative to the fitting element, the connecting element, which is used to mount the door element on the pivot point and/or the axis, can be freely adjusted to the position of the pivot point and/or the axis, at least within a range that is at least between 50 mm to 80 mm. The adjustment of the connecting element to the pivot point and/or the axis can advantageously be continuously adjusted by moving the holding element relative to the fitting element. It is therefore z. B. possible to align a door element, which is clamped in the corner fitting according to the invention, also on a pivot point and/or an axis that is outside the norm, namely outside of, for example, 55 mm, 65 mm or 70 mm.

In this respect, the corner fitting according to the invention is suitable for compensating for error tolerances caused by the displaceable or floating holding element, which is in operative connection with the connecting element. Overall, the ease of assembly for arranging a door element, in particular a glass door element, on a pivot point and/or an axis is therefore improved by the inventive design of the corner fitting according to the invention.

According to the invention, both fitting elements have a free space as a guide, in which the holding element can be moved. For the purposes of the application, free space is to be understood, for example, as a recess, a slot or a groove which runs in the longitudinal extension of the fitting elements. However, in the context of the present invention, free space is also understood as the distance formed between the two fitting elements, which enables the retaining element, which has a head part and a connecting part, to be moved with the connecting part in the free space between the fitting elements. In contrast, the free space designed as a recess, slot or groove, which runs in the longitudinal extension of the fitting elements, is used to movably mount the holding element with its head part or to attach the holding element via the head part to at least one fitting element in a non-positive and/or positive manner attach.

In order to obtain the setting after the adjustment of the door element on the pivot point and/or the axis, the displaceability of the retaining element is prevented in that this force and/or is positively connected via the headboard in the free space. As a result, the holding element, and thus also the connecting element operatively connected to the holding element, is fixed in its position relative to the fitting elements, as a result of which the orientation or adjustment of the door element to the pivot point and/or the axis is retained. It is of course also conceivable that the displaceability of the holding element, which is in operative connection with the connecting element, is prevented by connecting the connecting element to at least one of the fitting elements via a fastening element in a non-positive and/or positive manner.

A fastening mechanism is advantageously suitable for the non-positive and/or positive connection between the holding element and the fitting element, which is integrated on the holding element and on the connecting element and which can be converted from a released state into a fixed state. In this way, after the corner fitting has been aligned or adjusted to the pivot point and/or the axis via the displaceable holding element and the connecting element operatively connected to the holding element, the fastening mechanism can be transferred to the fixing state, whereby the holding element can be force- and/or positive contact comes to at least one fitting element and thereby the connecting element is fixed in its position on the pivot and / or the axis.

Of course, it is also conceivable to limit the stepless displaceability of the holding element by holding it in certain positions, for example by means of locking means. will Retaining element, for example, guided in a groove or on a rail on or between the fitting elements, corresponding configurations in the groove or on the rail could, for example, be used to set up the door element on standardized pivot points and/or axes of 55 mm, 65 mm or 70 mm, For example, locking means or breakpoints can be formed that noticeably restrict the free displacement of the holding element. If the locking means or holding points designed in the groove or on the rail are reached, the holding element can advantageously be pushed further in the groove or on the rail relative to the fitting element beyond the locking means or holding points if the alignment of the door element to the Pivot point and/or the axis requires, namely when the pivot point and/or the axis is outside the norm, namely outside of 55 mm, 65 mm or 70 mm.

In a particularly advantageous manner, the holding element and the connecting element which is operatively connected to the holding element and which is used to mount the door element on a pivot point and/or an axis are two components of the corner fitting which are connected to one another. As already stated, these interconnected components preferably form the fastening mechanism, which is advantageously integrated on both components, namely on the holding element and on the connecting element, and which can be switched between the released state and the fixing state, with the holding element being attached in the released state the fitting elements is displaceable and is fixed in the fixing state at least non-positively or positively on at least one fitting element. Accordingly, the fastening mechanism formed on the holding element and on the connecting element is used on the one hand to move the corner fitting to a pivot point and/or to set an axis, ie to move the holding element and the connecting element connected to the holding element relative to the fitting elements and in particular relative to the longitudinal extent of the fitting elements. In addition, the fastening mechanism serves to fix the corner fitting in the set position, namely to fix the holding element to at least one of the fitting elements via the fastening mechanism, at least in a non-positive or positive manner.

In order to establish an operative connection between the holding element and the connecting element, ie to form the fastening mechanism, the holding element and the connecting element are particularly advantageously connected to one another in a non-positive and/or positive manner via at least one fastening element. The fastening element between the holding element and the connecting element can be, for example, a screw, such as a screw. B. act a grub screw that connects the holding element and the connecting element together. At least two fastening elements are particularly advantageously provided, which connect the holding element to the connecting element. The non-positive and/or positive connection between the holding element and the connecting element, ie the transfer of the fastening mechanism from the released state to the fixed state, also advantageously serves to fix the holding element to the fitting element. For this purpose, the fitting element has a free space as a guide, for example in the form of a recess, a groove or a rail, on or in which the holding element is guided or movably mounted. The free space in the fitting element is advantageously designed in such a way that the holding element extends in the longitudinal direction of the fitting element can be displaced or guided. Since the fitting element or the fitting elements of the corner fitting are aligned parallel to the front and/or rear surface of the door element, the displacement of the holding element in the longitudinal extension of the fitting element results in a displacement of the door element with the fitting element in the opposite direction to the displacement of the holding element in Longitudinal extension of the fitting element. This makes it possible, for example, to align the door element within a frame on the longitudinal sides of the frame and on the pivot point and/or the axis. If the door element could not be moved relative to the pivot point, a swing door set up on a fixed pivot point and/or a fixed axis could, for example, unintentionally contact a wall or another glass component with one of its edges if the pivot point and/or the axis were misaligned. If a stop of the swing door is at least partially configured on another glass door element or on the wall, the door element could swing past the stop if the corner fitting is misaligned or if the pivot point and/or the axis is misaligned.

According to the invention, the free space designed as a recess, groove or slot is designed in both fitting elements. The recess, the groove or the slot extend in the longitudinal extension of both fitting elements and run in the two fitting elements at the same height and parallel to one another. The free space in the fitting elements, referred to as a recess, groove or slot, advantageously serves to guide the holding element essentially parallel to the fitting elements and relative to their longitudinal extent. For this purpose, the holding element has the head part, which serves to ensure that the holding element is held in place at least in the released state of the Fastening mechanism is movably mounted in the free spaces of both fitting elements. Due to this configuration, the clamping of the retaining element via the head part acts on both fitting elements in the fixing state of the fastening mechanism, namely in the recesses of both fitting elements, whereby the clamping force acting during the clamping is advantageously distributed evenly over both fitting elements.

In the simplest case, in an embodiment not according to the invention, the holding element can also be designed as a flat element without a head part that can be guided between the fitting elements in the longitudinal extent of the fitting elements. It is conceivable that grooves, for example in the form of oblong holes, are formed in the fitting elements, which allow a continuous non-positive and/or positive fastening of the retaining element via fastening elements that engage through the grooves and the retaining element along the grooves. Of course, a groove can also be provided in just one fitting element, through which fastening elements can engage with the holding element. For example, after aligning the door element with the pivot point and/or the axis, the holding element could be fixed in its position by at least one fastening element, for example a screw or a pin, extending through the groove of the fitting element. Since, as already described, the retaining element is operatively connected to the connecting element, the fastening element that reaches through the groove and connects the fitting element to the retaining element in a non-positive and/or positive manner also connects the connecting element that is used to mount the door element on the pivot point and / or the axis is used, fixed in its position.

The connecting part and the head part of the holding element are advantageously designed as a common, monolithic and/or one-piece component. A monolithic component is to be understood as meaning a component produced from one or more different components, for example by injection molding. However, a one-piece component can also be understood to mean a component made of one material, which is milled out of the metal block, for example by machining a metal block. A common component is preferably also to be understood in such a way that the head part and the connecting part are designed as individual parts which are provided as a common component, namely as a holding element in a preassembled state.

In an embodiment not according to the invention, the retaining element is advantageously designed as an L-profile with a head part and a connecting part, preferably in the form of two surfaces that are essentially orthogonal to one another, with the head part in the free space designed as a groove, slot or recess in one of the fitting elements is movably mounted in the released state of the fastening mechanism and has a clamping effect in the recess in the fixed state of the fastening mechanism, and the connecting part is in operative connection with the connecting element. If both fitting elements have a free space designed as a groove, slot or recess, the head part of the holding element or the holding element is designed according to the invention as a T-profile in order to movably mount or clamp the holding element in both recesses of the fitting elements. By transferring the fastening mechanism from its released state to the fixed state, the retaining element designed as a T-profile offers free spaces of the fitting elements on both sides, ie in both grooves, slots or recesses at least partially a bearing surface which serves for the non-positive and/or positive connection between the holding element and the fitting elements, ie the head part has a clamping effect in both grooves, slots or recesses in the fixing state of the fastening mechanism. In contrast to the holding element designed as an L-profile, the holding element designed as a T-profile clamps evenly on both sides of the corner fitting, namely on both fitting elements. As a result, in contrast to the retaining element designed as an L profile with the retaining element designed as a T profile, a more stable non-positive and/or positive connection, ie improved clamping between the retaining element and the fitting elements, can be achieved. As already described for the retaining element designed as an L-profile, the connecting element is also connected to the retaining element via a connecting part in the case of the retaining element designed as a T-profile.

In addition to the free space in the longitudinal extension of the fitting elements in at least one of the fitting elements designed as a groove, slot or recess, there is preferably a free space formed in the form of a distance between the fitting elements, which enables the holding element to be guided between the fitting elements at least relative to their longitudinal extension, with the connecting part of the support member extends through the gap. In a preferred manner, the free space formed as a distance between the fitting elements is designed to be larger than the material thickness of the connecting part. The distance is preferably at least 10% greater in relation to the material thickness of the connecting part, in order to always ensure sufficient mobility of the holding element, regardless of the glass thickness of the door element clamped in the corner fitting to be able to ensure via its connecting part in the free space formed as a distance between the fitting elements.

To support the compact design of the fitting according to the invention, the head part and the free space of the fitting elements designed as a groove, slot or recess are designed in such a way that the head part with an area of less than 10 cm ² rests on a surface of the free space designed as a recess. The L-shaped head part of the holding element rests in particular with a surface of less than 5 cm ² on a surface of the recess. Despite the small contact surface, a relatively heavy door element, for example a 12 mm thick glass door element, can also be mounted on a pivot point and/or an axis with the corner fitting, without losing the clamp between the holding element and the fitting elements when the fastening mechanism is in the fixed state.

In order to support the movement of the holding element, which is connected to the connecting element via the connecting part, in the longitudinal extent of the fitting elements, a lower recess is designed on the fitting elements, which is preferably formed parallel to the recess designed as a free space and which preferably extends over the same Length as designed as a free space extends recess. The lower recess is preferably formed in both fitting elements and extends over the distance between the fitting elements from one fitting element to the other. The lower recess is advantageously used to move the connecting element in the longitudinal extension of the fitting elements with the holding element, at least in sections. To shift the connecting element over the entire length of the To ensure lower recess, the contour of the lower recess is adapted to the outer contour of the connecting element. If the outer contour of the connecting element has, for example, rounded corners, the contour of the recess also has rounded corners which correspond to the shape and the radius of the rounded corners of the outer contour of the connecting element. The rounded corners of the contour of the recess also advantageously serve to prevent the connecting element from tilting in the edge regions of the lower recess.

The connecting element and the holding element are advantageously designed as a common, monolithic and/or one-piece component. A monolithic component is to be understood as meaning a component produced from one or more different components, for example by injection molding. A one-piece component is also understood to be a component made from a material, which is worked out of the material, for example, by machining a material, for example a metal block. A common component is preferably also to be understood in such a way that the holding element and the connecting element are individual parts that are provided as a common component in a preassembled state.

The one-piece construction of the retaining element with the connecting element offers the advantage that fastening elements that are used to connect the retaining element to the connecting element can be dispensed with. In this one-piece configuration of the retaining element with the connecting element, the retaining element is advantageously fixed to the fitting elements by Fastening elements, such as screw connections, pins or, for example, latching options.

In the present application, the following terms should be understood as follows:
A "retaining element" should be understood to mean a component that can be displaced essentially parallel to the fitting elements, which serves to displace the connecting element that is operatively connected to the retaining element parallel to the fitting elements and to contact at least one fitting element in a force-fitting and/or form-fitting manner reach.

A "connecting element" is to be understood as meaning a component accommodating the pivot point and/or the axis. In order to increase the variability of the connecting element, this receptacle can have different sizes or can be adapted to receptacles with different sizes, for example by means of adapter inserts. The connecting element can be a separate component that is operatively connected to the holding element via fastening elements, or it can also be designed with the holding element as a common, monolithic and/or one-piece component.

The "stepless selection of the pivot points" is to be understood in a range of about 45 mm to 80 mm. Of course, if required, the corner fitting according to the invention can also be designed in such a way that pivot points can be selected outside of the range described above. However, this would then require that the door element would have to be cut out in a larger than usual area and the corner fitting would have to be dimensioned accordingly in order to be able to expand the displaceability of the holding element between the fitting elements.

"Free space designed as a recess in at least one fitting element" can be understood as a free space designed in the form of grooves, ridges, grooves, shoulders, rails, projections, slots and/or, for example, roller bands, which has a displaceable, i. H. movable storage of the holding element allowed. Of course, latches can be provided along the free space, which allow the holding element to latch and thus allow the door element to be preset to predetermined predetermined pivot points and/or axes. However, it is also possible for only locking and/or stopping options to be configured on standardized pivot points and/or axes.

A method according to the invention for arranging a door element on a pivot point and/or an axis via an adjustable corner fitting according to the invention, comprising a first fitting element and a second fitting element, which each have at least partially a contact section for the contact of the door element and are connected to one another while the door element is clamped , essential to the invention provides that a connecting element, which is movably mounted in the corner fitting, is aligned with the pivot point and/or the axis and after aligning the connecting element with the pivot point and/or the axis, the connecting element is connected with at least one fitting element in a non-positive and/or positive manner. Compared to known assembly methods, the method according to the invention is much easier to carry out, since, for example, the corner fitting with the door element clamped therein is adjusted to the pivot point and/or the axis via the displaceably mounted connecting element and the connecting element also serves to adjust the setting to the pivot point and/or to fix the axle by means of a positive connection with at least one fitting element.

In order to avoid repetitions here with regard to the advantages of the method according to the invention, reference is made to the description of the advantageous embodiment of the corner fitting according to the invention and it is referred to in its entirety.

Further measures improving the invention are presented in more detail below together with the description of a preferred exemplary embodiment of the invention with reference to the figures.

In the different figures, the same parts are always provided with the same reference symbols, which is why they are usually only described once.

figure 1 shows a door element 3, which is mounted via a corner fitting 1 on a pivot point 2, which can also be a BTS axis (floor door closer axis), for example. The corner fitting 1 is clamped to the door element 3 in the lower left corner of the door element 3 . The Indian figure 1 Corner fitting 1 shown is designed in such a way that it could also be clamped to the upper left or upper right or lower right corner of the door panel 3 for mounting the door panel 3 on a pivot point 2 and/or an axis. The corner fitting 1 has a first fitting element 4 and a second fitting element 5 . Both fitting elements 4 and 5 have contact sections 6 which are used at least for indirect contact via an intermediate layer, not shown here, for contact with the door element 3 . A clamping area 7 is formed between the fitting elements 4 and 5, into which the door element 3 can be inserted. A holding element 8 is arranged between the two fitting elements 4 and 5, which is displaceable relative to the fitting elements 4 and 5, namely in the longitudinal extension of the fitting elements 4 and 5. For mounting the door element 3 on the pivot point 2 and/or the axle a connecting element 9 that is operatively connected to the holding element 8 is used. The holding element 8 which is in operative connection with the connecting element 9 is movably guided in a free space 11 designed as a recess in the form of a groove in the fitting element 4 and the fitting element 5 . The free space 11 is designed parallel to the longitudinal extension of the fitting elements 4 and 5 in the form of the groove. As a result, the holding element 8 and the connecting element 9, which is operatively connected via the fastening elements 10, can be displaced along the recess 11.1 in parallel, ie to or in the longitudinal extent of the fitting elements 4 and 5. Because the connecting element 9 with the holding element 8 can be displaced in the opposite direction relative to the door element 3, the door element 3 can be continuously aligned with the pivot point 2 along the axis BB, for example in its position in a door frame or a glass door system. Is z. B. the pivot point 2 or the pivot axis of the door element 3, which is represented by the axis AA, outside the areas defined for the usual pivot points 2, namely outside of 55 mm, 65 mm or 70 mm, the door element 3 can be moved by moving the Retaining element 8 and thus operatively connected to the retaining element 8 connecting element 9 are adjusted to the pivot point and / or the axis. The holding element 8 and the connecting element 9 are in the present case designed as two components which are connected to one another and which comprise the fastening mechanism which is presently integrated in both components, namely in the holding element 8 and the connecting element 9 . For the transfer of the fastening mechanism from a released state in which the holding element 8 is movably mounted in the longitudinal extension of the fitting elements 4 and 5, in the Fixing state, the fastening elements 10, which connect the holding element 8 to the connecting element 9 via the connecting part, are screwed into the bushings 12. When the fastening elements 10 are screwed into the connecting part of the holding element 8, the head part 8.1 of the holding element is clamped at least in sections, at least in a non-positive manner in the free space 11 designed as a recess 11.1 in the form of a groove on the fitting elements. In the fixing state of the fastening mechanism, the displaceability of the holding element 8 and of the connecting element 9 operatively connected to the holding element 8 is prevented or the holding element 8 is fixed in its position on the fitting elements 4 and 5 .

In order to support the movement of the holding element 8, which is connected to the connecting element 9 via the connecting part 8.2, in the longitudinal extension of the fitting elements 4 and 5, a lower recess 18 is designed on the fitting elements 4 and 5, which is preferably parallel to the free space 11 designed recess 11.1 is formed and which preferably extends over the same length as the designed as a free space 11 recess 11.1. The lower recess 18 is preferably formed in both fitting elements 4 and 5 and extends over the distance 17 of the fitting elements from one fitting element 4 and 5 to the other.

figure 2 shows the corner fitting 1 without the front fitting element 4 to better illustrate the mounting of the holding element 8 in the corner fitting 1. As can be seen, the door element 3 has a cutout outside the contact section 6 in accordance with the known glass cutout standards and lies outside the cutout on the contact sections 6 of the fitting elements 4 and 5. In the area of Section of the door element 3 creates a free space in the corner fitting 1 which serves to arrange the holding element 8 and the connecting element 9 . In addition, from the figure 2 It can be seen that the fastening mechanism comprises only the holding element 8 and the connecting element 9, which are connected to one another via two fastening elements 10 that can be operated through the passages 12 configured on the connecting element 9. The tightening of the fastening elements 10 has the effect that the holding element 8 engages, at least in a non-positive manner, in the free space 11 of the fitting element 5, which is designed as a recess 11.1 in the form of a groove. When the fastening mechanism is in the fixed state, only a small part of the surface of the head part 8.1 of the holding element 8 rests on a surface of the free space 11 designed as a recess 11.1.

figure 3 shows the rear fitting element 5, the holding element 8 and the connecting element 9 in the unassembled state. As can be seen, the contact section 6 is only configured in certain areas. The contact section 6 follows in particular the contour of the cut-out corner area of the door element 3. Fastening elements 10, which are not shown here, are used for the non-positive and/or positive connection between the connecting element 9 and the holding element 8. The fastening elements 10 are guided or screwed through passages 12 configured in the connecting element 9 in the form of bores, which are advantageously designed in the form of internally threaded bores into which a fastening element 10 configured as a screw engages in a non-positive and positive manner. Together with the fastening elements 10, the connecting element 9 and the holding element 8 form the fastening mechanism, which moves from a displaceable mounting of the holding element 8 in a released state to a fixed state is transferable, in which the holding element 8 is at least non-positively coupled to the fitting element. In the state of the non-positive coupling of the holding element 8 to the fitting element 4 and/or 5, a previously made alignment or adjustment of the corner fitting to the axis or the pivot point can be fixed.

The connecting element 9, which is operatively connected to the holding element 8, has a receptacle 13 approximately in the middle, which is used to arrange the door element 3 on the pivot point 2 and/or the axle. The receptacle 13 can advantageously be adapted to the pivot point 2 and/or the axis, for example using different adapters. Since the connecting element 9 in the present exemplary embodiment is a single component of the corner fitting, it can of course also be variably connected to the holding element 8 with receptacles 13 of different sizes and form the fastening mechanism. To connect the holding element 8 to the connecting element 9 , cutouts 14 are formed in the connecting element 9 in the area of the passages 12 , which are used to receive pins 15 formed on the holding element 8 , which are formed on the connecting part of the holding element 8 . The pins 15 each have a bore 16 through which the fastening elements 10, which are guided in the bushings 12, engage. The fastening elements 10 are preferably used on the one hand to transfer the fastening mechanism, which is formed, among other things, from the connecting element 9 and the holding element 8, into different functional states. On the other hand, the connecting element 9 and the holding element 8 are connected in a non-positive and positive manner via the fastening elements 10 and thus form a preassembled one-piece component. The ones on the head part of the holding element 8 configured surface is guided in the fitting element 5 in the configured as a recess in the form of a groove free space 11.
