EP3029237B1 - Corner fitting - Google Patents

Description

The present invention relates to a corner fitting for a door element which can be arranged on a pivot point and / or an axis according to the preamble of claim 1.

Corner fittings are already known from the prior art, which allow an arrangement of door elements, in particular glass door elements, on a pivot point or an axis. The known corner fittings are designed in such a way that they allow the door element to be arranged on a pivot point and / or an axis with a rear axle dimension of 55 mm, 65 mm or 70 mm. The door elements or the glass doors that can be arranged on the pivot point and / or the axis via the known corner fittings are, for example, glass swing doors that are arranged, for example, on a BTS axis.

The generic corner fittings mostly consist of two fitting elements, each of which has a contact section for the door element, the door element being clamped in a clamping or clamping area between the contact sections. So that the door element, in particular the glass door, can be arranged on the pivot point and / or the axis, this is cut out in the area of the corner fitting, in particular outside the clamping or clamping area of the corner fitting, forming a cutout. Thus, outside the contact sections, that is to say outside the clamping or clamping area, namely in the cutout area of the glass door element, a free space is formed which is used to place the door element on the To arrange the fulcrum or the axis taking up, for example, an axle body.

For the arrangement of the door element on the pivot point and / or the axis, a connecting element is used in the known corner fittings, which is either integrally designed with one or both of the fitting elements, or which is optionally held as a single component between the fitting elements. The only adjustment option in the known corner fittings is to arrange the connecting elements in a forward or backward position, for example in a recess in a retaining element, in order to adjust the door element clamped in the corner fitting to standardized pivot points or axes of 55 mm, 65 mm or 70 mm.

From the EP 2 617 925 A1 a clamp fitting for glass doors is known which has a receptacle for a rotation axis in the form of a connecting plate. The connecting plate has a receiving area for an adjusting element in the form of a recess. The recess is designed similar to an elongated hole, which is used to accommodate the adjustment element in a forward or backward direction in order to be able to adjust the glass element on an axis with a rear axle dimension of 55 mm or 65 mm. The disadvantage of the known adjusting element is that it is only received in the recess in two positions. Adjustment outside of the forward or backward direction of the adjusting element in the recess is not possible with the known clamp fitting.

the WO 03/009 734 A1 describes a clamping fitting for a glass element, which is adjustable by means of an intermediate part on a glass element. The intermediate part has an elongated hole which serves to move the intermediate part with the clamping fitting relative to the glass element clamped therein. A displacement of the intermediate part relative to the clamping fitting, that is to say relative to the fitting elements, is possible with that of the WO 03/009 734 A1 known clamp fitting not possible. Since the intermediate part can only be moved with the clamping fitting relative to the glass door element, when setting the glass element, for example, on a pivot point or an axis, it is not possible to pay attention to a uniform gap between the clamping fitting and, for example, a side part adjoining the glass element, or the gap dimension is not uniform be respected.

For example, from DE 85 36 840 U1 , which discloses all the features of the preamble of claim 1, EP 0 035 143 A2 and U.S. 5,203,115 A known corner fittings, the alignment between the connecting element and the fitting elements is possible.

It is therefore the object of the present invention to design a corner fitting in such a way that it can be adjusted, for example, at least to pivot points and / or axes that have a standardized or a non-standardized rear axle dimension.

The above object is achieved by a corner fitting with the features of claim 1. Further advantages, features and details of the invention emerge from the subclaims, the description and the drawings.

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, each of which at least regionally have a contact section for contact with the door element and can be connected to one another by clamping the door element, includes the technical Teaching that a holding element is arranged between the two fitting elements, which is displaceable relative to the fitting elements and the holding element is in operative connection with a connecting element is used to mount the door element on the pivot point and / or the axis, a fastening mechanism being integrated between the fitting elements in such a way that the position of the holding element can be reliably fixed by means of static friction acting between the fitting element and the holding element, which can be introduced via the fastening mechanism.

This solution offers the advantage that with the holding element which is displaceable relative to the fitting element, the connecting element which is in operative connection with the holding element can be displaced. Correspondingly, the connection 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 via the displacement of the retaining element relative to the fitting element, at least within a range that is at least between 50 mm to 1 mm. The setting of the connecting element to the pivot point and / or the axis is advantageously continuously adjustable by shifting the holding element relative to the fitting element. It is therefore z. B. possible to align a door element that is clamped in the corner fitting according to the invention to a pivot point and / or an axis that is outside the norm, namely outside of 55 mm, 65 mm or 70 mm. In this respect, the corner fitting according to the invention is suitable to compensate for error tolerances due to the displaceable or floating retaining element which is in operative connection with the connecting element. In a particularly advantageous manner, the holding element and the connecting element which is in operative connection with the holding element and which serves to support the door element on a pivot point and / or an axis are two connected to one another Components of the corner fitting. According to the invention, these interconnected components form a fastening mechanism which is integrated between the two fitting elements on both components, namely the retaining element and the connecting element, and which can be converted from a released state to a fixed state and vice versa, the retaining element on the fitting elements in the released state is displaceable and in the fixing state is at least non-positively or positively attached to at least one fitting element. Accordingly, the fastening mechanism formed on the retaining element and the connecting element serves on the one hand to adjust the corner fitting to a pivot point and / or an axis, ie to move the retaining element and the connecting element connected to the retaining element relative to the fitting elements and relative to the longitudinal extension of the fitting elements. On the other hand, 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 force-fitting or form-fitting manner. According to the invention, the position of the holding element is reliably fixed by means of static friction which acts between the fitting element and the holding element and which can be introduced via the fastening mechanism. Because of the static friction, the position of the holding element is advantageously fixed without wear. Finally, the integration of the fastening mechanism into the holding element and the connecting element allows a compact design of the fitting according to the invention.

After setting the corner fitting, that is, after moving the retaining element and the one that is operatively connected to the retaining element Connecting element relative to the fitting elements, an adjustment or positioning of the holding element takes place via a non-positive and / or positive connection on the fitting elements, the fastening mechanism initiating a frictional connection between the fitting element and the holding element, which supports the static friction. The displacement of the holding element relative to the fitting element can be implemented in a stepless manner. Correspondingly, with the holding element according to the invention for a corner fitting, a door element can be freely set to the pivot point and / or the axis, that is to say the position of the pivot point and / or the axis. With the corner fitting according to the invention, door elements can advantageously be adjusted to the rear axle dimensions of a pivot point and / or an axis in a range that is at least between 40 mm to 1 mm, and preferably between 50 mm to 75 mm.

In order to establish an operative connection between the holding element and the connecting element, that is to say to form the fastening mechanism, the holding element and the connecting element are 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. 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 Set the retaining element on the fitting element. For this purpose, the fitting element 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 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 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 the 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.

According to the invention, the free space in at least one of the fitting elements is designed as a recess. The recess preferably extends in the longitudinal direction of the fitting element and in a particularly advantageous manner 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 at least released State of the fastening mechanism is movably mounted in the recess of one or both fitting elements.

According to the invention, the fastening mechanism is designed in such a way that, in the released state, static friction acts between the holding element and the recess that is significantly less than the static friction that acts between the holding element and the recess in the fixed state. The fastening element and preferably at least two fastening elements, via which the static friction between the recess and the holding element can be adjusted, are used to increase the static friction from the released state to the fixed state of the fastening mechanism. 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 increased. When the fastening element is unscrewed, the static friction between the holding element and the recess is reduced and the fastening mechanism is brought into the released state.

According to the invention, the static friction between the holding element and the recess is increased to such an extent that the holding element is fixed to at least one of the fitting elements via the fastening mechanism. In the fixation state, a clamp acts 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 fixed state of the fastening mechanism, the with the Holding element in operative connection connecting element 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 designed in such a way that the holding element executes a lifting movement within the free space when transferring from the fixed state to the released state and vice versa. 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 retaining element is advantageously designed as an L-profile with a head and a connecting part, preferably in the form of two substantially orthogonal surfaces, the head part in a free space designed as a groove, slot or recess in one of the fitting elements in the released state of the The fastening mechanism is movably supported and acts in a clamping manner in the recess in the fastening 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 surface that is used for non-positive and / or form-fitting connection between the holding element and the hardware elements. In this case, when the fastening mechanism is in the fixation state, the head part of the holding element acts in a clamping manner 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.

In an embodiment not according to the invention, the connecting part and the head part of the holding element are 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 made from the material block, for example, by machining a block of material, for example a metal block is worked out for example by milling. 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 pre-assembled state.

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 is preferably arranged on the connecting element accessible to the user from the outside. Since the connecting element is in operative connection with the holding element, which is guided between the fitting elements and is therefore difficult to access, the fastening mechanism and in particular the holding element can advantageously be removed from its fixed state via the fastening elements that can be operated from the outside of the connecting element. H. from the clamping with the free space designed as a recess, into the released state, d. H. to produce the stepless displaceability in the longitudinal extension of the fitting elements and vice versa.

So that the holding element can perform a lifting movement through the fastening elements, which are preferably externally accessible to the user on the connecting element, and in order to form the fastening mechanism integrated on the holding element and on the connecting element, the holding element has at least one bore into which the fastening element at least partially engages in the fixation state , whereby the increased clamping between the holding element and the recess acts. In the detached state, the fastening element preferably engages less far into the bore one or is located at a distance from the bore, so that the clamping is less or the clamping is almost canceled.

So that the fastening element is accessible from the outside on the connecting element, the connecting element has at least one passage in which the fastening element is arranged, the passage extending in particular as far as the bore. To form the fastening mechanism, which includes a lifting movement of the holding element, the leadthrough is preferably not aligned with the bore in the released state.

In order to move the bore relative to the passage in order to generate a lifting movement of the holding element, the bore according to the invention has means which cause the connecting part to move perpendicular to the direction of movement of the fastening element when the fastening element engages in the bore. The extent to which the fastening element engages in the bore is decisive for the extent of the stroke movement of the holding element. If the fastening element engages less in the bore or if the fastening element is spaced apart from the bore, ie rotated out of the bore, the holding element performs a lifting movement in the vertical direction from the fastening element and is released. To clamp the holding element, the fastening element engages further into the bore, the holding element being pulled perpendicular to the direction of movement of the fastening element towards the fastening element via the means, such as the configuration of the bore with a chamfer that rises from the edge of the bore to the center of the bore and is clamped in the recess. Since the bushings are used to pass through the fasteners, and the Fastening elements are advantageously screws, the leadthroughs preferably have an internal thread which is used for a non-positive and / or positive connection with the fastening elements designed as screws. Because the bore or the bores of the holding element are not aligned with the feedthroughs of the connecting element and the bores are chamfered outwards, for example, the fastening element guided in the internal thread of the feedthrough is pushed or rotated along the chamfer of the bore. However, since the internal thread of the bushing serves as an abutment for the fastening element, the holding element is moved along the chamfer with the advance of the fastening element, in particular perpendicular to the direction of movement of the fastening element. In this case, the holding element, which is guided in the free space of the fitting element designed as a recess, comes to rest against the recess in a force-locking manner. In order to improve the propulsion of the fastening element along the means designed as a bevel or to ensure this, the fastening element in the front region which engages with the bore preferably has a conical surface which corresponds approximately to the slope of the bevel, ie the Bevel is adjusted.

Of course, it is also conceivable that the bore itself has an internal thread for a non-positive and / or positive connection with the fastening element. The passage in the connecting element can then optionally be designed as a bore with an internal thread or without an internal thread, through which the fastening element is propelled in the direction of the bore of the holding element.

According to the invention, the holding element is moved perpendicular to the parallel guide by bringing the fastening element into engagement with the bore. During the vertical movement of the holding element this is fixed to at least one fitting element via at least one engagement section which is formed on one of the surfaces of the holding element. The engagement section of the holding element is a section of a surface of the holding element that is guided in the recess or in the free space and is located on the head part of the holding element. If, according to the invention, the connecting element is coupled non-positively and / or positively to the holding element, the engagement section is coupled non-positively and / or positively in or on the recess. A displacement of the connecting element for aligning the door element on the pivot point and / or the axis is therefore only possible by decoupling the non-positive connection between the holding element and the fitting element. The non-positive decoupling of the retaining element from the fitting element takes place, as already mentioned, by releasing the non-positive and / or positive connection between the connecting element and the retaining element. Correspondingly, the force-fit decoupling between the holding element and the fitting element is resolved in that the fastening element is driven out of the bore or rotated and, via a vertical movement of the holding element, releases the holding element from a clamping position into a free position. In order to then re-connect the retaining element to the fitting element in a non-positive manner, the fastening element must be driven forward again in the direction of the bore. When the fastening element is advanced into the bore, the holding element is then moved in the opposite vertical direction, the engagement section on the head part of the holding element then being positively connected to the fitting element and the holding element being in its clamping position.

In a particularly preferred manner, the head part has contact surfaces on both sides, which preferably include the engagement sections, which serve to guide the holding element in both fitting elements and to force on both sides, i.e. with both fitting elements and here in particular in the recesses of the fitting elements designed as free space - and / or to get to the system in a form-fitting manner. In addition, bearing surfaces designed on both sides of the head part of the holding element have the further advantage that the holding element is not only displaceable parallel to the fitting elements, but can also be displaced or displaced between the fitting elements, i.e. one or the other fitting element. As a result, not only the corner fitting can be adjusted to the rear axle dimension of the pivot point or the axis via the retaining element, but rather a plane offset of the pivot point or the axis, i.e. an offset of the door element clamped with the corner fitting to, for example, a side part, can also be adjusted via the retaining element be approximately balanced.

In addition, with the retaining element according to the invention, which is preferably designed as a clamping plate in the form of a T-profile, the door element can be adjusted around the pivot point and / or the axis, namely the door element in a certain angular range, via an inclined position of the retaining element between the fitting elements aligned around the pivot point or the axis.

In order to increase the clamping, i.e. the friction between the holding element, and in particular between the engagement section of the holding element and the recesses formed in the fitting elements, the holding element preferably has a surface with increased roughness and / or corrugation in the area of the engagement section on, for example in the form of a diamond pattern. The surface of the engagement portion of the retaining element is advantageously designed so that the clamping or the friction between the retaining element and the fitting element ensures an increased force and form fit compared to a smooth surface, which is achieved via the door closer on the corner fitting or on the door element absorbs or compensates for the applied torque. Of course, it is also conceivable that the free space in the fitting element configured as a recess also has such a surface that acts, for example, as a counter-holding means for the surfaces configured on the engagement sections of the support surfaces of the holding element.

The surface of the engagement section of the head part and / or of the free space configured as a recess in the fitting element advantageously has a surface roughness which is preferably formed by a periodic profile or by an aperiodic profile. A periodic profile can advantageously be formed by turning or milling, for example a wave profile. An aperiodic profile can advantageously be formed by grinding or eroding. In this case, the underside of the head part, which faces the connecting element, advantageously has the increased surface roughness, at least in sections, namely preferably in the area of the engagement section.

In order to increase the force between the engagement section and the recess, the periodic profile advantageously runs transversely to the longitudinal extension of the recess. As a result, the positioning of the holding element on the fitting element can advantageously be set in locking steps by toothing the profile of the recess with the profile of the engagement section.

In order to be able to hold the holding element in a non-slip manner when the fastening mechanism is in the fixation state on the fitting element, the engagement section and / or the recess has a surface with increased slip resistance. A coating of polymer material can preferably be applied to the surfaces as the slip-resistant material. Polymers, such as copolymers composed of various monomers such as polyesters, polyurethanes and polyamides, or homopolymers consisting of only one type of monomer, such as polyethylene, polypropylene, polyvinyl chloride and polyamide, and polymer alloys formed by mixing different polymers and copolymers, are preferably used as the polymer material.

The polymer material is preferably an elastomer material, such as, for example, thermosetting plastics, thermoplastics, elastomers or thermoplastic elastomers.

In the present application, the following terms should be understood as follows, but this understanding of the terms should not be viewed as limiting.

A "holding element" should be understood to mean a component that can be moved essentially parallel to the fitting elements, that is, is displaceable and advantageously also rotatable and is used to move the connecting element that is operatively connected to the holding element parallel to the fitting elements and to move it into the clamping area clamped door element to align a pivot point and / or an axis. The holding element can be designed as a single-surface or multi-surface body. Of course you can the holding element also consists 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. In an advantageous manner, the holding element is designed as a T-profile made of plastic, metal, in particular made of steel, stainless steel, aluminum or a metal alloy or made of a plastic coated with a metal. In contrast, the fitting elements are advantageously designed as die-cast aluminum fittings.

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 which is brought into operative connection with the holding element via fastening elements.

"Free space which is designed as a recess in at least one fitting element" can be understood as a free space designed in the form of grooves, grooves, grooves, shoulders, rails, projections, slots and / or, for example, roller tapes, which is a displaceable, ie movable mounting of the holding element allowed. Of course, latching means can be configured along the free space, which engage the holding element and thus pre-set the door element enable specified 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.

If the recess is designed in the form of grooves, grooves, shoulders and / or projections, the engagement section of the holding element or the engagement sections of the holding element advantageously has corrugations, grooves, grooves, grooves, shoulders or projections that fit into the grooves, Grooves, grooves, shoulders and projections of the recess engage positively.

It should be noted that the figures are only of a descriptive character and are not intended to restrict the invention in any way.

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

Fig. 1 shows a holding element 1 according to the invention for one in the Figures 5 and 6th The holding element 1 is designed as a clamping plate in the form of a T-profile with a head part 1.1 and a connecting part 1.2, the holding element 1 at least in sections over the head part 1.1 in a free space 110 in each case designed as a recess in the fitting elements 40 and 50 of the corner fitting 10 can be guided and non-positively and / or positively clamped on or in the free spaces 110 of the fitting elements 40 and 50. The head part 1.1 is designed in one piece with the connecting part 1.2, the connecting part 1.2 being perpendicular to the head part 1.1. In the present case, the connecting part 1.2 comprises a narrow web 2, which at each end merges into a pin 3. The pins 3 are used to connect the holding element 1 with a connecting element 90, which preferably has recesses 140 which serve to accommodate the pins 3 configured on the holding element 1 on the connecting part 1.2. The pins 3 each have a bore 4 through which the fastening elements 100 engage, which are guided in passages 120 of the connecting element 90, and above that connect the connecting element 90 to the holding element 1 in a non-positive and positive manner, and which together with the holding element 1 and the Connecting element 90 form a fastening mechanism.

The head part 1.1 of the holding element 1 with bearing surfaces 5 configured on both sides on the underside of the head part 1.1 is advantageously guided on both sides in the free spaces 110 of the fitting elements 40 and 50. In order to increase the force fit and / or form fit between the holding element 1 designed as a T-profile with the fitting elements 40 and 50, the bearing surfaces 5 have engagement sections 6 which are profiled as corrugations in the form of a diamond pattern. The corrugation can also be designed as a cross corrugation or as a parallel corrugation. The corrugation can be configured on the support surfaces 5, pointing in all directions.

In Fig. 2 the holding element 1 is designed as a flat molded body which only comprises a connecting part 1.2. In order to move the flat molded body, namely the holding element 1 shown, relative to the fitting elements 40 and 50 and to fix it to the fitting elements 40 and 50 via fastening elements 100, a recess 4 in the form of an elongated hole is designed in the connecting part. Although the position of the fastening elements 100 is fixed on the fitting elements 40 and 50, the holding element 1 can thus be used via the recess 4 configured as an elongated hole when the fastening elements 100 are passed through the elongated hole be moved at least partially parallel to the fitting elements 40 and 50, in particular parallel to the contact sections 60 of the fitting elements 40 and 50. Both the arrangement of the fastening elements 100 in the fitting elements 40 and 50 and the size of the recess 4 are limiting for the displacement of the holding element 1 and the fixing of the holding element 1 by the fastening elements 100 guided through the recess 4.

Like that in the Fig. 1 shown, designed in the form of a T-profile as a clamping plate holding element 1, the flat, as in the Fig. 2 The holding element 1 shown can be connected to a connecting element 90 or designed as a common, monolithic and / or one-piece component with the connecting element 90, the connecting element 90 preferably having a receptacle 130, for example for an axle body of a rotational axis.

In Fig. 3 is that in Fig. 1 The holding element 1 shown is shown in a front view. The pin 3, via which the holding element 1 is connected to the connecting element 90, adjoins the web 2 of the connecting part 1.2 at the bottom. The head part 1.1 is designed orthogonally to the connecting part 1.2, that is to say in the present case also orthogonal to the pin 3, which is advantageously encompassed by the connecting part 1.2. The head part 1.1 protrudes on both sides with the bearing surfaces 5 beyond the connecting part 1.2. For better clamping, i.e. to increase the force fit and / or form fit between the holding element 1, here in particular between the bearing surfaces 5 and the recesses 110 configured in the fitting elements 40 and 50, the bearing surfaces 5 each have an engagement section 6. In the present case, the engagement section 6 is designed as a corrugation.

Fig. 4 shows the holding element 1 from Figures 1 and 3 in a plan view of the underside. As can be clearly seen in this view, the connecting part 1.2 expands in the end regions designed as pegs 3. In other words, the web 2 of the connecting part 1.2 tapers compared to the pin 3 configured at the end. This can reduce friction between the fitting elements and the connecting part, which advantageously facilitates the displaceability of the holding element 1 in the detached state of the fastening mechanism. As shown, the engagement section 6 is designed as a corrugation in the form of a diamond pattern over the entire length of the support surface 5 of the holding element 1.

Fig. 5 shows a door element 30, which is mounted via a corner fitting 10 on a pivot point 20, which can also be a BTS axis, for example. The corner fitting 10 is clamped in the lower left corner of the door element 30.
