Description

The present invention relates to a corner fitting for a door element, in particular for a glass door element, according to the preamble of claim 1 and a method according to claim 12.

Corner fittings are known from the prior art which allow an arrangement of door elements of different thicknesses, in particular glass doors with different glass thicknesses, on a pivot point or an axis. The glass doors are, for example, glass swing doors that are arranged via the known corner fittings, for example on a BTS axis in connection with a side part. The structure of the known corner fittings usually comprises two fitting elements, each having a contact section for the door element, an intermediate layer being inserted between the contact sections and the door element, which at least partially corresponds to the contour of the contact sections and which is encompassed by the contact section. Outside the contact sections, the fitting elements form a free space within a section of the door element, which is used to accommodate, for example, an axis between the fitting elements. In order to be able to clamp door elements, in particular glass door elements, of different thicknesses between the fitting elements, the known corner fittings are dimensioned in such a way that they can accommodate a door element with a certain glass thickness in a delivery state, ie in an initial position, for example with a glass thickness of 15 mm. If you want another glass door element with a Clamping a glass thickness of 10 mm, the intermediate layer is reinforced in the known corner fitting in order to be able to compensate for the difference between the glass thicknesses. In this example, the intermediate layers on both sides of the glass door element are reinforced by 2.5 mm. As a result of the reinforcement of the intermediate layers, the fitting elements resting on both sides of the door element move away from the door element by 2.5 mm. With the fitting elements, cover or cover elements that grip around the fitting elements also move away from the door element by 2.5 mm on both sides. Accordingly, a gap of 2.5 mm is automatically created on both sides of the door element, namely between the surfaces of the door element and the lid or cover element that covers the fitting elements on both sides. If you want to prevent this gap formation, the delivered lid or cover element, which is designed with the corner fitting designed for a 15 mm glass thickness of the door element, must be replaced on both sides of the door element with a deeper lid or cover element. In the extreme case, namely in the case of a corner fitting that is aligned with a 15 mm thick glass door element which is to be converted to accommodate a 7 mm thick glass door element, for example, the intermediate layers would have to compensate for the difference between 15 mm and 7 mm. This means that the intermediate layer must be reinforced by 4 mm on both sides of the door element. This increases the overall depth of the known corner fittings on both sides of the door element by 4 mm. In addition, the increasingly stronger intermediate layers reduce the clamping of the door element between the fitting elements and thus the strength of the known corner fittings.

DE 10 2009 022803 A1 and FR 2 122 031 A5 disclose a corner fitting for a glass door element, with an exchangeable rigid spacer element which is arranged between the fitting elements outside the contact sections, the spacer element forming a counter-bearing to the contact sections and the door element that can be clamped in the clamping area.

It is therefore the object of the present invention to at least partially address the disadvantages of the prior art described above remedy. In particular, it is the object of the present invention to provide a corner fitting which allows an extended setting option, namely the setting for different door elements with different door leaf thicknesses, in particular with different glass thicknesses, and in which the distance between the fitting elements and the clamped door element is independent of whose door leaf thickness is constant.

The above object is achieved by a corner fitting with the features of claim 1 and by a method with the features of claim 12.

This solution offers the advantage that the spacer element between the fitting elements, ie within the corner fitting, serves as a counter bearing, and thus the distance between the fitting elements and the door element, namely in particular in the area of the contact sections that each include the intermediate layer that contacts the door element, always remains constant relative to the door element. This means that, according to the invention, the intermediate layer always remains in the contact position with the door element, regardless of the thickness of the door element clamped between the fitting elements, since the spacer element can be replaced according to the door leaf thickness, in particular the glass thickness, of the door element and or the spacer element adapted to the glass thickness of the door element can be replaced. The size of the spacer element and the door leaf or glass thickness of the door element determine the distance between the fitting elements relative to one another. However, the adaptation of the corner fitting according to the invention to, for example, different glass door elements with different glass thicknesses does not change the distance between the fitting elements relative to the door element. This has the advantage that a frame or cover encompassing the fitting elements always rests on the glass door element regardless of its thickness, since the intermediate layer, which is usually arranged between the fitting elements and a glass door element, always remains constant. In this respect, the use of the spacer element can advantageously prevent the formation of gaps between the fitting elements and the door element. This automatically means that on both sides of the door element, the overall depth of the corner fitting according to the invention, regardless of the door leaf or glass or material thickness of the Corner fitting according to the invention clamped door element is always the same.

Since the interchangeable rigid spacer element can be used to adjust the corner fitting according to the invention variably to the door leaf or glass thickness of the door element clamped over the corner fitting when the material thickness of the spacer element changes, the thickness of the intermediate layer, which is arranged between the fitting elements and the door element, can advantageously be adjusted , and which is encompassed by the contact sections always remain constant, whereby an exchange of the intermediate layer is obsolete according to the invention regardless of the glass thickness of the clamped door element. In this way, regardless of the door elements clamped in the corner fitting according to the invention with different thicknesses, a constant stability of the corner fitting with the same material thickness of the intermediate layer can be guaranteed. In addition, the constant intermediate layer on both sides of the door element and, with a simultaneous increase in the variability of the corner fitting according to the invention, reduce its system costs.

The fitting elements advantageously have a holder which is provided outside the contact sections on which the spacer element is arranged. In an advantageous manner, the spacer element is held at least over one of its ends in a holder configured on the fitting element in a force-locking and / or form-locking manner, in particular in a form-locking manner. With its other end, which is not held in the holder, the spacer element is then preferably supported on the opposite fitting element. By shifting the setting options outside of the ranges of the System sections, each comprising at least one intermediate layer, the corner fitting according to the invention, while maintaining the intermediate layer and maintaining the clamping area, which is limited by the fitting elements, can advantageously be adjusted by exchanging the spacer elements that are inserted into the brackets arranged outside the system sections.

In order to be able to accommodate the spacer element, the holder, which can be configured in one or both fitting elements or arranged on them, has a receptacle in which the spacer element extends. The receptacle is preferably a recess, for example a bore, a blind hole or a milled recess, the contour of which, i. H. whose shape is preferably adapted to the outer contour of the spacer element. If, for example, the spacer element is designed as a polygonal element, for example in the form of a polygonal rod, the bore or milling is advantageously configured as a polygonal hole or polygonal milling. Of course, the spacer element can also be designed in the form of a round rod, in which case the bore or the milling is advantageously adapted to the shape of the round rod. The design of the spacer element as a round rod or polygonal element should not be understood as restrictive, rather all contours of the spacer element are conceivable, the outer contour of which can be represented in the bore or milling in the fitting element in order to be able to accommodate the spacer element with a positive fit.

The fitting elements are advantageously designed with a lower recess in which the connecting element can be displaced, in particular a floor area being formed as a free space between the fitting elements and the floor area in which the spacer element is formed and / or the holder is arranged at approximately the same height as the lower 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 used advantageously to move the connecting element in the longitudinal extension of the fitting elements with the holding element, at least in sections. In order to ensure a displacement of the connecting element over the entire length of the 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 rounded corners, for example, 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 lower recess ensures that the connecting element, without coming into contact with the glass door element, can be shifted in the cutout formed by the glass door element, preferably in the longitudinal extension of the fitting elements in the free space formed on the floor area. So that the spacer element is also arranged between the fitting elements without having contact with the glass door element, it is advantageous to place the spacer element or the holder that receives the spacer element at approximately the same height as the lower recess in the one between the fitting elements preferably to arrange free space formed in the floor area. The holder is advantageously arranged in direct adjoining the lower recess on or in at least one of the fitting elements.

In order not only to form a counter-bearing to the contact sections and the door element clamped in the clamping area via just one spacer element, it is advantageous to arrange at least one second spacer element on at least one fitting element that is approximately parallel to the first spacer element at the same height. For example, in the case of a "universal" glass cutout, a first spacer element can be arranged between the fitting elements on the outer edge of the corner fitting. A second spacer element could then be arranged approximately parallel at the same height as the first spacer element on the opposite outer edge between the fitting elements. The two spacer elements then jointly form a counter-bearing to the contact sections and the door element clamped in the clamping area, whereby the stability of the corner fitting according to the invention is increased overall.

The spacer elements are advantageously arranged on both sides adjacent to the lower recess in the free space formed in the floor area between the fitting elements. The spacer elements can be arranged in holders only on one fitting element or alternately on both fitting elements.

It is of course also conceivable that the corner fitting according to the invention is structurally designed on a glass door element with a glass thickness of 8 mm, so that, based on this structural configuration, it is fully functional without the use of a spacer element, the fitting elements resting against one another at least in sections outside the contact sections . To adapt the aforementioned corner fitting to a door element with a thicker glass, for example a glass thickness of 15 mm, spacer elements are used arranged between the fitting elements, which must be adapted to the size, ie the thickness of the 15 mm thick glass door element, namely the size of which corresponds to the difference between the 8 mm thick glass door element and the 15 mm thick glass door element. In the case described, the spacer element would then have to extend over 7 mm between the fitting elements, namely to bridge a distance of 7 mm between the fitting elements. In other words, this means that the spacer element or the spacer elements is or are adapted to the spacing of the fitting elements, which is predetermined by the thickness of the door element used. In order to simplify the adaptation of the corner fitting according to the invention to the glass thicknesses of the door element to be clamped, the glass thicknesses can be noted on the spacer elements. If, for example, the corner fitting according to the invention is designed in the delivery state for door elements with a door leaf thickness of 8 mm, an assortment of spacer elements can be provided in a kit with the corner fitting, which enables the conversion or adaptation of the corner fitting to door elements, for example with 15 mm, 18 mm and 22 mm allowed. The spacer elements are advantageously made available in pairs, with reference to the door leaf thickness, namely 15 mm, 18 mm or 22 mm, preferably on the spacer elements or on a packaging.

Advantageously, the holder forms a common component with a fitting element, the component advantageously being in one piece and / or being monolithic. A monolithic component is to be understood as 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, for example, is produced by machining a material, for example a metal block from which material is carved out. A common component is preferably also to be understood as meaning that the holder and the fitting element are individual parts that are provided as a common component in a pre-assembled state.

Since the corner fitting according to the invention is preferably designed for mounting a door element on an axis of rotation or a pivot point, the corner fitting according to the invention comprises a holding element which is in operative connection with a connecting element via which the door element clamped in the clamping area between the fitting elements is on the pivot point and / or the axis of rotation can be aligned. In this case, the connecting element is preferably connected via fastening elements to a holding element which allows the door element to be continuously adjusted to non-standardized pivot points. According to the invention, these interconnected components form a fastening mechanism which is advantageously integrated on both components, namely on the holding element and on the connecting element, and which can be transferred between a released state and a fixed state, the holding element being displaceable on the fitting elements in the released state and is at least non-positively or positively attached to at least one fitting element in the fixation state. Accordingly, the fastening mechanism formed on the holding element and on the connecting element advantageously serves to adjust the corner fitting steplessly to a pivot point and / or an axis, that is to say the holding element and the connecting element connected to the holding element are steplessly adjusted relative to the fitting elements and in particular relative to the longitudinal extension of the fitting elements move. In addition, the fastening mechanism serves to keep the corner fitting in the set To fix position, namely to fix the holding element on at least one of the fitting elements via the fastening mechanism at least in a non-positive or positive manner. Correspondingly, the holding element for setting the connecting element to the pivot point and / or the axis with the connecting element can be freely displaceable, ie according to the invention continuously displaceable to the longitudinal extent of the fitting elements. If the position of the connecting element is set to the pivot point and / or the axis, the fastening mechanism fixes the retaining element and thus also at least indirectly the connecting element in the form of a non-positive clamping connection with at least one of the fitting elements via the retaining element, which is preferably designed as a clamping plate.

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 force-fitting and / or form-fitting manner via at least one fastening element. The fastening element between the holding element and the connecting element can, for example, be a screw, such as, for. B. act a grub screw that connects the holding element and the connecting element to one another. At least two fastening elements which connect the holding element to the connecting element are particularly advantageously provided. To adjust the fastening mechanism, in particular to transfer the fastening mechanism from the released state to the fixed state and vice versa, the fastening element or the fastening elements are preferably arranged on the connecting element accessible to the user from the outside. Since that Connecting element is in operative connection with the holding element, which is guided between the fitting elements, and this is therefore difficult to access, the fastening mechanism and in particular the holding element can advantageously be removed from its fixed state, ie from being clamped with the as Recess designed free space, in the released state, ie to produce the continuous displaceability in the longitudinal extension of the fitting elements and vice versa.

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 serves according to the invention to fix the holding element on the fitting element. For this purpose, the fitting element according to the invention has a free space as a guide, in the form of a recess, a groove or a rail, on or in which the holding element is guided or is movably mounted. The free space in the fitting element is designed according to the invention in such a way that the holding element can be displaced or guided in the longitudinal extension of the fitting element. 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 retaining 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 retaining 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 those If the door element could not be displaced 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 are incorrectly positioned. 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 incorrectly adjusted or if the pivot point and / or the axis are incorrectly positioned.

The retaining element is advantageously designed as an L-profile with a head part and a connecting part, preferably in the form of two substantially orthogonal surfaces, ie the head part is oriented perpendicular to the connecting part, the head part being in a groove, Slot or recess configured free space in one of the fitting elements movably mounted in the released state of the fastening mechanism and acts in a clamping manner in the recess in the fixed state of the fastening mechanism. 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 advantageously designed 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 holding element designed as a T-profile offers on both sides, that is, in both free spaces of the fitting elements designed as a groove, slot or recess, at least in sections a support section which is used for the non-positive and / or positive connection between the Holding element and the fitting elements are used. The acts in the fixation state Fastening mechanism clamping the head part of the holding element in both grooves, slots or recesses. 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 holding element designed as an L-profile with the holding element designed as a T-profile, a more stable force and / or form fit, ie improved clamping between the holding element and the fitting elements, can be achieved. As already described for the holding element designed as an L-profile, the connecting element is also connected to the holding element via the fastening element in the case of the holding element designed as a T-profile via a connecting part.

According to the invention, the free space in at least one of the fitting elements is designed as a recess. The recess extends in the longitudinal direction of the fitting element and advantageously in each case in the longitudinal direction of the two fitting elements, the recesses in the two fitting elements preferably being designed at the same height and parallel to one another. The free space designated as a recess in the fitting elements is particularly preferably designed as a groove or slot and 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 movably supported in the recess of one or both fitting elements, at least in the released state of the fastening mechanism.

The fastening mechanism is advantageously designed in such a way that, in the released state, static friction acts between the holding element and the recess which is significantly less than the static friction which acts between the holding element and the recess in the fixed state. To increase the static friction from the released state to the fixed state of the fastening mechanism, the fastening element is preferably used and, more preferably, at least two fastening elements, via which the static friction between the recess and the holding element can be adjusted. If, for example, the fastening element designed as a screw is screwed into the holding element via the connecting element, the static friction between the holding element and the recess is preferably increased. When the fastening element is unscrewed, the static friction between the holding element and the recess is advantageously reduced and the fastening mechanism is transferred to the released state.

The static friction between the holding element and the recess is preferably increased to such an extent that the holding element is fixed to at least one of the fitting elements via the fastening mechanism. According to the invention, in the fixing state there is a clamping between the holding element and the recess, the clamping preventing a movement of the holding element relative to the fitting element. With the clamping and the fixed positioning of the holding element in the fixing state of the fastening mechanism, the connecting element which is in operative connection with the holding element is also fixed in its position relative to the fitting elements.

Against the background of a compact design of the corner fitting according to the invention, whereby only little installation space is required, the fastening mechanism is preferably designed in such a way that during the transition from the fixed state to the released state and vice versa, the holding element executes a lifting movement within the free space. Since the fastening mechanism is integrated in the holding element and the connecting element, no further components are required to form the fastening mechanism. In particular, the free space designed as a recess in the fitting elements serves not only to continuously guide the retaining element in the longitudinal direction to the fitting elements but also to receive the retaining element at least in a clamping manner, namely at every position in the recess.

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 a component produced, for example, from one or more different components using the injection molding process. However, a one-piece component can also be understood to be a component made from a material that is machined from the material block, for example by milling, by machining a block of material, for example a metal block. A common component is preferably also to be understood as meaning 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 pre-assembled state.

Since the maximum spacing of the fitting elements or the maximum size of the spacer elements is limited by the support section of the retaining element, the support section of the retaining element is at least dimensioned in such a way that the fitting elements are spaced from an initial position plus / minus 10 mm, preferably plus / minus 15 mm mm and particularly preferably plus / minus 20 mm. This means that, for example, support sections of the retaining element in the form of a T-profile that are guided in the recesses of the fitting elements on both sides can each be guided out of the recesses of the fitting elements by at least 5 mm. However, if you want to compensate for a plane offset between the door element and a side part adjoining it, for example, with the corner fitting according to the invention, it is advantageous if the support sections of the holding element that are guided in the recesses on both sides are dimensioned so that they are on both sides, i.e. H. can each be guided out of one or the other fitting element or from the recesses of the fitting element by at least 10 mm or into the recesses of the opposite fitting element.

Of course, it is also conceivable, in an embodiment not according to the invention, for the spacer element or spacer elements to be designed at least with one fitting element as a common, monolithic and / or one-piece component. In order to be able to adapt a corner fitting designed in this way to door elements of different thicknesses, the fitting elements, which are designed as a monolithic and / or one-piece component with the spacer elements, would have to be exchanged as an overall component. In order to adapt a fitting element designed as a common component with an already pre-assembled spacer element to a different door leaf thickness, the already pre-assembled spacer element (s) would have to be replaced with spacer elements provided from the range.

The principle of the variability of the clamping area is to be understood in the sense of the present invention for corner fittings and in particular also for all door fittings of any type and shape. In particular, door fittings should be understood to mean, for example, locks and counter lock cases which are to be clamped on door leaves of different thicknesses, in particular on glass doors with different glass thicknesses or glass thicknesses. The features mentioned in the description and in the claims as well as the features of the corner fitting shown and described in the figures can also be applied to the fittings individually or in any combination.

In the present application, the following terms should be understood as follows:
A “spacer element” should be understood to mean a spacer element and preferably at least two or more spacer elements. The spacer element or the spacer elements can be alternately received non-positively and / or positively, and in particular positively, on the fitting elements and are supported on the other fitting element. Of course, the spacer elements can also only be received in brackets on only one fitting element and are then supported on the opposite fitting element.

A “rigid spacer element” is understood to mean a component that extends to a predefined extent between the fitting elements and that corresponds to the material thickness of a door element or, for example, the material thickness of elements such as Side or top parts of an all-glass door system, which are clamped in the corner fitting according to the invention, can be selected from an assortment of spacer elements of different sizes.

The "holding element" is intended to be a movable essentially parallel to the fitting elements, i. E. H. displaceable and advantageously also rotatable component are understood, which serves to move the connecting element operatively connected to the holding element parallel to the fitting elements and align this with a door element clamped in the clamping area about a pivot point and / or an axis. The holding element can be designed as a single-surface or multi-surface body. Of course, the holding element can also consist of one or more interconnected struts or otherwise, such as. B. be designed as an elbow. The free space available between the fitting elements, which is formed by the spacing of the fitting elements from one another, is only limiting for the type and design of the holding element.

A “connecting element” should be understood to mean a component that accommodates the pivot point and / or the axis. To increase the variability of the connecting element, this receptacle can have different sizes or can be adapted to receptacles with different sizes by means of adapter inserts, for example. 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 as a common, monolithic and / or one-piece component with the holding element. The corner fitting according to the invention should not only serve to adapt the clamping area to door elements with different thicknesses, in particular with different glass thicknesses, but should also be designed in such a way that it can be used for stepless selection of different pivot points or axle points, ie different rear axle dimensions in a range of approximately adjustable from 45 mm to 80 mm. In addition, a plane offset between the door element and, for example, a side part should be adjustable with the corner fitting according to the invention. An angular offset of the door element in relation to a side part or in a frame should also be able to be compensated for, ie adjusted, with the corner fitting according to the invention.

"Free space which is designed as a recess in at least one fitting element" can be understood to mean a free space designed in the form of grooves, grooves, grooves, shoulders, rails, projections, slots and / or, for example, roller tapes, which has a displaceable, i. H. movable storage of the holding element allowed. Of course, latching means can be configured along the free space which enable the retaining element to latch into place and thus the door element to be pre-set to predetermined pivot point dimensions and / or axis dimensions. However, it is also possible for only locking and / or stopping points to be configured on standardized pivot points and / or axes. A stepless displaceability of the holding element in the free space is advantageously ensured between two locking means or between two locking and / or stopping points, whereby a fine adjustment of the corner fitting to non-standardized pivot points can be carried out.

1. 1) Demontage der Beschlagelemente,
2. 2) Entfernen des Distanzelements aus der Halterung,
3. 3) Einsetzen eines neuen Distanzelements in die Halterung,
4. 4) Montage der Beschlagelemente.

The inventive method according to claim 12 for setting a corner fitting according to one of claims 1 to 11 on a door element, in particular on a glass door element, in order to have different material thicknesses of the door element The following steps are taken to incorporate the corner fitting:

1. 1) Dismantling the hardware elements,
2. 2) Remove the spacer from the bracket,
3. 3) inserting a new spacer element into the bracket,
4. 4) Assembly of the hardware elements.

The method is advantageously facilitated using the corner fitting according to the invention to the effect that an exchange of the intermediate layers, which are encompassed by the contact sections of the fitting elements, is not necessary, which saves at least one work step. Rather, apart from an assortment of spacer elements of different sizes, there is no need to replace, for example, the frame that engages around the fitting elements in order to cover up a gap between the door element and the fitting elements resting on it on both sides.

In order to avoid repetition with regard to the advantages of the method according to the invention, reference is made to the description of the advantageous References embodiment of the corner fitting according to the invention and it is fully reverted to this.

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

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

In the Figure 1 A and B a corner fitting 100 known from the prior art is shown in a front view of the part of the corner fitting 100 that can be arranged on an axis of rotation. The corner fitting 100 comprises two fitting elements 30 and 40 which interlock in the lower part via a contour. Above this contouring, the fitting elements 30 and 40 form a receiving or clamping area 70 for a door element 20. For this purpose, the fitting elements 30 and 40 each have contact sections 50 and 51, which each bear indirectly on both sides of the door element 20 via an intermediate layer 60. Through the in the Figures 1 A and B The illustrated front view of the corner fitting 100 can only be seen that part of the contact sections 60 that tapers towards the axis of rotation. Because the contact sections 50 and 51 taper in the direction of a receptacle for the axis of rotation, below the door element, which has a cutout that roughly follows the contact sections 60 with its contouring, in the front part of the in Figure 1 A and B shown Corner fitting 100 formed a free space below the door element 20 in order to be able to accommodate or arrange the corner fitting 100 on an axis of rotation or a fulcrum.

As Figure 1 A As shown, the corner fitting 100 known from the prior art is structurally aligned with a door element 20 with a relatively thick glass. This means that the thickness of the intermediate layers 60 can be kept so low that a cover placed on the fitting elements 30 and 40 and encompassing the fitting elements 30 and 40 rests on the surfaces of the door element 20. In the present case, the cover that engages around the fitting elements 30 and 40 is not shown. Would you like the one from the Figure 1 A Use the corner fitting 100 shown here to arrange a door element 20 on a pivot point or a pivot axis, the door element 20 having a lower glass thickness, the known corner fitting 100 must be adapted to the lower glass thickness of the glass door element via intermediate layers 60, the intermediate layers 60 being made correspondingly stronger must be to the glass door element, as in Figure 1 B shown, which has a lower glass thickness than that in Figure 1 A door element 20 shown has to be able to receive or to be able to clamp in the clamping area between the fitting elements 30 and 40. A cover or cover element, like this one in Figure 1 A would be used to cover the fitting elements 30 and 40, then no longer lies against the glass door element 20, so that a gap would be seen between the cover and the surfaces of the glass door element 20, which is created on both sides of the door element. In addition, a thicker intermediate layer 60 can lead to the clamping or clamping of the door element 20 between the fitting elements 30 and 40 in the clamping area 70 becoming more unstable, which in particular can impair the longevity of the corner fitting 100. In the maximum case In the course of the stress on the known corner fitting 100, the material properties of the intermediate layers 60 change so that the door element 20 tilts out of the clamping or clamping area 70 and thereby, for example, a floor is damaged or damaged itself. This could possibly be counteracted if the connection between the fitting elements 30 and 40 were readjusted when the known corner fitting was stressed, for example to press a brittle or softer intermediate layer 60 with a higher pressure onto the surfaces of the door element 20 clamped in the clamping area 70. Even if the corner fitting 100 known from the prior art could solve the problems identified, namely, for example, by means of a deeply drawn cover element, which rests on the surfaces of the door element 20 even when a narrower glass door element 20 is clamped, and if the materials of the intermediate layer 60 are so would be improved so that they retain the material properties for the duration of the operation of the known corner fitting 100, it is still disadvantageous that with narrower door elements 20, ie with door elements 20 with a low glass thickness, the depth of the known corner fitting 100 upon insertion of thicker liners 60 would increase.

In the Figures 2 to 5 a corner fitting 1 according to the invention is shown, with which the problems of a corner fitting 100 known from the prior art are altogether solved.

Figure 2 shows an exploded view of a corner fitting 1 according to the invention without the frame surrounding the fitting elements 3 and 4 and a cover element fastened to the frame. The corner fitting according to the invention comprises the fitting elements 3 and 4 1 at least regionally designed contact sections 5 and 5.1, which are used to contact a door element 2, which is clamped between the fitting elements 3 and 4 on an axis of rotation or a pivot point. Since the fitting elements 3 and 4 are preferably made of a metal, a metal alloy or, for example, a plastic metal alloy, the contact sections 5 and 5.1 each include an intermediate layer 6 that lies between the contact sections 5 and 5.1 and the door element 2. Since the door element 2 is preferably a glass door element, the intermediate layer serves, on the one hand, to prevent metal from resting on glass. On the other hand, the intermediate layers 6 support the damping properties of the corner fitting 1 according to the invention, increase the friction quotient between the glass door element and the fitting elements 3 and 4 and also serve as screw locking for the fastening means 14, via which the fitting elements 3 and 4 are preferably connected to one another, even with low elasticity . For this purpose, the intermediate layers 6 are preferably made from a plastic material or a rubber-elastic material. Of course, the intermediate layers 6 can also be made from Ferrolastic soft materials or metal-elastomer compounds, as are known, for example, for cylinder head gaskets in the motor vehicle sector. In particular when using the corner fitting 1 according to the invention for the arrangement of glass door elements 2 which serve as fire protection doors, metal-elastomer connections which can withstand high thermal loads can be important for the intermediate layers 6. In the lower area of the fitting elements 3 and 4, a holder 9 is provided, which is used for the arrangement, ie for the insertion of exchangeable rigid spacer elements 8 and 8.1. In the fitting element 4, the holder 9 is a recess in the form of a blind hole, which for at least a form-fitting reception of the spacer element 8.1 is used. The holder 9 shown for the fitting element 3 for inserting the rigid spacer element 8 is designed as a separate component which, for example, engages or can be inserted into a bore, in particular into a blind hole formed on the fitting element 3. The holder 9 of the fitting element 3, like the holder 9 of the fitting element 4, also has a recess which is used for insertion or for a form-fitting connection with the spacer element 8. As in the following Figures 3 and 4th shown, the holder 9 inserted into the fitting element 3 can optionally be dispensed with, depending on the type of glass cutout of the door element 2, but this does not affect the functioning of the remaining spacer element, here the spacer element 8.1, and the functioning of the corner fitting 1.

A connecting element 11, which is operatively connected to a holding element 10, is used to mount the door element 3 on the pivot point 2 and / or the axis. The holding element 10 has a head part 10.1 and a connecting part 10.2. In the present case, the connecting element 11 is operatively connected to the holding element 10 via two fastening elements 15 in a non-positive and / or form-fitting manner on the connecting part 10.2 and together with the connecting element 11 forms the fastening mechanism. The retaining element 10, which is in operative connection with the connecting element 11, is movably supported via the head part 10.1 in a free space 13 designed as a recess in the form of a groove in the fitting element 3 and the fitting element 4. The free space 13 is configured in the form of a recess configured as a groove parallel to the longitudinal extension of the fitting elements 3 and 4. As a result, the holding element 10 and the connecting element 11, which is operatively connected via the fastening elements 15, are parallel in the free space 13, ie to or in The longitudinal extension of the fitting elements 3 and 4 is displaceable. Because the connecting element 11 with the holding element 10 can be displaced in the opposite direction relative to a clamped door element 2, the door element 2 can be continuously aligned with a pivot point, for example in its position in a door frame or a glass door system. Is z. B. the pivot point or the axis of rotation for the door element 2 outside the normalized areas for the usual pivot points, namely outside of 55 mm, 65 mm or 70 mm, the door element 2 can be moved by moving the retaining element 10 with the connecting element 11 operatively connected to it Pivot point and / or the axis can be adjusted. In the present case, the holding element 10 and the connecting element 11 are designed as two components that are connected to one another, which include the fastening mechanism that is integrated in the present case in both components, namely in the holding element 10 and the connecting element 11. To transfer the fastening mechanism from a released state, in which the holding element 10 can be displaced in the longitudinal extent of the fitting elements 3 and 4 in the free space 13 designed as a recess, into the fixing state, the fastening elements 15, which the holding element 10 via the connecting part with the Connect the connecting element 9, screwed into the bushings 12. When the fastening elements 15 are screwed into the connecting part 10.2 of the holding element 8, the head part 10.1 of the holding element is at least partially clamped in a force-locking manner in the free space 13 designed as a recess in the form of a groove or slot on both sides of the fitting elements 3 and 4 Displaceability of the holding element 10 and that which is operatively connected to the holding element 10 The connecting element 11 is prevented or the holding element 10 is fixed on the fitting elements 3 and 4.

For the non-positive and / or positive connection between the connecting element 11 and the holding element 10, fastening elements 15 are used, as described, which are guided through passages 18 in the form of bores configured in the connecting element 11. The passages 18 or bores are advantageously designed in the form of internally threaded bores. The fastening elements 15 in the form of screws engage in the bushings 18 designed as internally threaded bores in an advantageous manner. The receptacle 16 can advantageously be adapted to the pivot point and / or the axis, for example by means of adapter inserts.

Since the connecting element 11 in the present exemplary embodiment is a single component of the corner fitting 1, it can of course also be connected to the holding element 10 in a variable manner with receptacles 16 of different sizes. To connect the holding element 10 to the connecting element 11, recesses 17 are designed in the connecting element 11 in the area of the passages 18, which are used to receive the connecting part 10.2 of the holding element 10, which is designed as a pin in the present case. The pins each have a bore 19 through which the fastening elements 15, which are guided in the passages 18, grip and thereby connect the connecting element 11 to the holding element 10 in a non-positive and / or positive manner. The orthogonal to the connecting part 10.2 head part 10.1 of the holding element is in the as a recess in the fitting elements 3 and 4 designed free space 13 guided or held. For this purpose, the head part 10.1 has support sections 12 which come to rest on contact surfaces configured in the free space 13. Tightening the fastening elements 15 results in increased static friction between the bearing sections 12 of the head part 10.1 of the holding element 10 and the contact surfaces of the free space 13 and 4 due to the contact of the support sections 12 of the head part 10.1 of the holding element 10 on the contact surfaces of the free space 13 of the fitting elements 3 and 4 thus to a frictional connection between the holding element 10 and the fitting elements 3 and 4. The frictional connection between the holding element 10 and the free space 13 of the fitting elements 3 and 4 can be reinforced by the fact that the support sections 12 of the head part 10.1 of the holding element 10 a superficial Corrugation, for example a diamond-shaped corrugation, which engages in a corrugation configured in the contact surfaces of the free space 13, so that there is also a positive connection between the holding element 10 and the fitting elements 3 and 4 in addition to the non-positive connection. In order to increase clamping, ie the friction between the holding element, in particular between the engagement or support section 16 and the free space 13 configured as a recess, the engagement or support section 16 advantageously has a corrugation. Of course, a holding element 10 configured as a clamping plate can also be clamped only by a force fit.

the Figures 3 A and B show the off Figure 2 corner fitting 1 shown without the fitting element 4, A in a plan view from below and in B in a side view. Also in the Figures 3 A and 3 B is, for the sake of clarity, a representation of a frame encompassing the fitting element 3 and a cover or cover plugged onto this frame. Lid element has been omitted. As in the Figures 3 A and B shown, the spacer elements 8 and 8.1 are arranged parallel to one another outside the contact section 5 approximately at the level of a lower recess 13.1 in the bottom area 13.2 of a free space formed between the fitting elements 3 and 4. The lower recess 13.1 serves to displace the connecting element 11 with the holding element 10 parallel to the longitudinal extension of the fitting elements 3 and 4. The contact section 5 is adapted to the glass section of the door element 2 clamped in the corner fitting 1. The contact section 5 as well as the intermediate layer 6, which is encompassed by the contact section 5, go in the right part, as in FIG Figure 3 shown, over the total height of the fitting element 3 and taper to the left following the glass cutout, so that below the glass cutout the free space for receiving the holding element 10 and the connecting element 11, which is operatively connected to the holding element 10, as well as for the arrangement of the spacer elements 8 and 8.1 between the fitting elements 3 and 4 is created. In the present case, the glass cutout configured in the door element 2 is a "universal" glass cutout. Since the size of the rigid spacer elements 8 and 8.1 can be adapted to the glass thickness of the door element 2, ie the spacer elements 8 and 8.1 are interchangeable, all door elements with a glass cutout "universal" with different glass thicknesses can be clamped with the corner fitting 1 according to the invention and, for example, arranged on an axis of rotation will.

the Figures 4 A and B also show the corner fitting 1 from the Figures 2 and 3 but here a door element 2 with an Italian glass cutout is clamped between the fitting elements 3 and 4. For reasons of illustration, only that is presented here Fitting element 3 is shown. It is in the Figure 4 A a plan view from below and in the Figure 4 B a side view of the corner fitting 1 according to the invention is shown. As can be seen in particular in FIG the door element 2 clamped between the fitting elements 3 and 4. Since the size of the spacer element 8.1 can be adapted to the glass thickness of the door element 2, ie the spacer element 8.1 is interchangeable, all door elements with an Italian glass cutout with different glass thicknesses can be clamped with the corner fitting 1 according to the invention and, for example be arranged on an axis of rotation.

The advantageous mode of operation of the corner fitting 1 according to the invention, namely in particular its constant overall depth with intermediate layers 6 remaining constant, is impressively illustrated by the illustration of the corner fitting according to the invention in a front sectional view in FIG Figures 5 A and B made clear.

In Figure 5 A a door element 2 is clamped between the fitting elements 3 and 4, which compared to the door element 2 from Figure 5 B has a glass thickness about twice as strong. For example, the door element 2 has a glass thickness of 15 mm Figure 5 A on. The door element 2 in Figure 5 B has, for example, a glass thickness of only 8 mm. As in both Figures 5 A and B can be seen, the distances between the fitting elements 3 and 4 and the door element 2, namely the same to its surfaces, since the intermediate layers 6 remain the same, namely these in comparison to the Figures 5 A and 5 B have the same material thickness, although the glass thickness of the clamped door element has roughly halved. Thus, the overall depth of the corner fitting 1 according to the invention can remain constant regardless of the glass thickness of the door element 2 received and regardless of the size of the clamping area 7. Since pressure is built up in the upper area of the corner fitting 1, namely between the fitting elements 3 and 4 on both sides of the door element 2 by tightening the fastening means 14, the force applied for the pressure being approximately in the middle of the sheet thickness of the door element 2, ie approximately in the middle of the clamping area 7 is equal to zero in the resultant, a similar force ratio between the fitting elements 3 and 4 must be built up in the lower area of the corner fitting 1, namely between the fitting elements 3 and 4 outside the clamping area 7. This is done according to the invention by the arrangement of the spacer element 8.1, which extends between the fitting elements 3 and 4 outside the clamping area 7 in the free space formed between the fitting elements 3 and 4 in the floor area 13.2 between the fitting elements 3 and 4 and extends to the fitting elements 3 and 4 supports. The size of the free space in the floor area 13.2 between the fitting elements 3 and 4 in Figure 5B is so small that the fitting elements 3 and 4 are almost in contact with one another. In contrast, the free space in the floor area 13.2 between the fitting elements 3 and 4, as in FIG Figure 5A shown, clearly more pronounced. The size of the spacer element 8.1 is determined by the glass thickness of the door element 2 and must be adapted at least to the extent that the spacer element 8.1 extends over the free space between the fitting elements 3 and 4. It can be seen that in Figure 5 A a larger spacer element 8.1 is used between the fitting elements 3 and 4 than in the Figure 5 B . This determines the difference in the glass thickness Figure 5 A to the glass thickness from the Figure 5 B the size difference between the spacer element 8.1 Figure 5 A and the spacer element 8.1 Figure 5 B .
