Description

DESCRIPTION

corner fitting

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

Corner fittings are already known from the state of the art, which enable door elements, in particular glass door elements, to be arranged about a center of rotation or an axis. Known corner fittings are configured in such a way that they allow an arrangement of the door element about a center of rotation and/or an axis with a rear axis dimension of 55 mm, 65 mm or 70 mm. Door elements or glass doors, which can be arranged on the center of rotation and/or axis via known corner fittings, are, for example, hinged doors of glass, which, for example, are arranged on a BTS axis.

According to the order, the corner fittings generally consist of two fitting elements, each of which has a contact section for the door element, the door element being clamped between the contact sections in a clamping or clamping area. So that the door element, in particular the glass door, can be arranged on the center of rotation and/or the axis, it is notched by the area of the corner fitting, in particular outside the clamping or clamping area of the corner fitting, forming a cutout. In this way, outside the contact sections, i.e. outside the clamping or holding area, specifically in the cut-out area of the glass door element, a free space is formed, which is used to arrange the locking element. door on the center of rotation or the axis, housing, for example, a shaft body.

For the arrangement of the door element on the center of rotation and/or the axis, in the case of known corner fittings, a connecting element is used, which is configured either integrally, that is, with one or with both hardware elements, or which is optionally fastened as an individual component between the hardware elements. As the only adjustment possibility, known corner fittings provide for arranging the connecting elements in a forward or reverse position, for example in a recess of a retaining element, in order to adjust the door element clamped in the corner fitting to centres. of rotation standardized or axles of 55 mm, 65 mm or 70 mm.

EP 2617925 A1 discloses a clamping fitting for glass doors, which has a receptacle for a pivot axis in the form of a connecting plate. The connecting plate has a receiving area for an adjusting element in the form of a cutout. In this case, the recess is designed similarly to a longitudinal hole, which serves to receive the adjusting element in a forward or reverse direction, in order to be able to adjust the glass element to an axis with a rear axis dimension 55mm or 65mm. A disadvantage of the known adjusting element is that it is accommodated in the recess in only two positions. An adjustment outside the forward or reverse direction of the adjusting element in the recess is not possible with the known clamping fitting.

WO 03/009 734 A1 describes a clamping fitting for a glass element, which can be attached to a glass element by means of an intermediate piece. In this connection, the intermediate piece has an elongated hole, which serves to displace the intermediate piece with the clamping fitting relative to the glass element clamped therein. A displacement of the intermediate piece relative to the clamping fitting, that is to say relative to the fitting elements, is not possible with the clamping fitting known from WO 03/009 734 A1. Since the intermediate piece can only be displaced relative to the glass door element with the clamping fitting, when adjusting the glass element, for example, on a center of rotation or an axis, attention cannot be paid to a dimension of Uniform gap between the clamping fitting and, for example, a side piece that borders the glass element, or the gap size cannot be kept uniform.

In the case of corner fittings known, for example, from DE 8536840 U1, which discloses all the features of the preamble of claim 1, from EP 0035 143 A2 and from US 5 203 115 A, it is Alignment between the connecting element and the hardware elements is possible.

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

The above object is achieved by means of a corner fitting with the features of claim 1. Other advantages, features and details of the invention result from the dependent claims, the description and the drawings.

The corner fitting according to the invention for a door element that can be arranged in a center of rotation and/or an axis, having a first hardware element and a second hardware element, which each have at least in some areas a contact section for contact with the door element and can be connected to one another by clamping the door element contains the technical teaching that a retaining element is arranged between the two hardware elements, which is displaceable in relation to the hardware elements and the retaining element is in operative connection with a connecting element, which serves for the accommodation of the door element in the center of rotation and/or axis, a clamping mechanism having been integrated in such a way between the hardware elements that a reliable fixation of the position of the clamping element can be achieved through static friction acting between the hardware element and the clamping element, which can be inserted through the clamping mechanism.

This solution offers the advantage that with the element displaceable relative to the fitting element, the connecting element can be moved in operative connection with the fastening element. Correspondingly, the connecting element, which serves to hold the door element in the center of rotation and/or axis, can be set to the position by moving the clamping element relative to the hardware element. of the center of rotation and/or of the axis freely selectable, at least within a range, which is at least between 50 mm to 1 mm. In this case, the adjustment of the connecting element to the center of rotation and/or the axis can be adjusted advantageously continuously by moving the clamping element relative to the fitting element. It is thus possible, for example, to align a door element, which is clamped in the corner fitting according to the invention, also about a center of rotation and/or an axis, which is/are outside of the norm, specifically outside of 55 mm, 65 mm or 70 mm. In this sense, the corner fitting according to the invention is suitable for compensating fault tolerances through the displaceably or floatingly mounted clamping element, which is in operative connection with the connecting element. Particularly advantageously, in the case of the retaining element and the connecting element, which is in operative connection with the retaining element, it serves to accommodate the door element at a center of rotation and/or an axis. , of two interconnected components of the corner fitting. According to the invention, these interconnected components form a fastening mechanism, which is integrated between the two hardware elements in both components, specifically in the fastening element as well as in the connecting element, and which can be worn from a released state to a fastening state and vice versa, the retaining element being fixed to the hardware elements in a displaceable manner in the separated state and in the fastening state at least positively and/or forcefully connected to at least one hardware element. As a result, the clamping mechanism formed on the clamping element and on the connecting element serves, on the one hand, to adjust the corner fitting to a center of rotation and/or an axis, i.e. to move the clamping element and the connecting element. connecting element connected to the fastening element in relation to the hardware elements and in relation to the longitudinal extension of the hardware elements. On the other hand, the fixing mechanism serves to fix the corner fitting in the fixed position, namely to fix the fixing element via the fixing mechanism of at least one of the fitting elements at least in a force-fit connection or in positive union. Reliable fixing of the position of the fastening element occurs according to the invention through a static friction acting between the hardware element and the fastening element, which can be introduced through the fastening mechanism. Due to static friction, the position of the clamping element is advantageously fixed in a wear-free manner. Finally, the integration of the fixing mechanism in the fastening element and the connecting element allows a compact construction of the fitting according to the invention.

After adjustment of the corner fitting, i.e. after displacement of the fastening element and the connecting element operatively connected to the fastening element in relation to the hardware elements, an adjustment or positioning of the fastening element takes place via a force-fit and/or positive connection to the hardware elements, the fixing mechanism introducing a force-drag connection between the hardware element and the fastening element, which favors static friction. In this connection, the displacement of the holding element relative to the fitting element can be carried out continuously. Consequently, with the clamping element according to the invention for a corner fitting, a door element can be freely adjusted in the center of rotation and/or the axis, that is to say, the position of the center of rotation and/or the axis . In this connection, with the corner fitting according to the invention, door elements can advantageously be adjusted to rear axis dimensions of a center of rotation and/or of an axis continuously in an area, which 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 fastening element and the connecting element, i.e. to configure the fastening mechanism, the fastening element and the connecting element are connected to each other via at least one connecting fastening element by force and/or positive drag. In the case of the fastening element between the fastening element and the connecting element, it can be, for example, a screw, such as, for example, a headless screw, which joins the fastening element and the connecting element to each other. Union. Particularly advantageously, at least two fastening elements are provided, which connect the retaining element with the connecting element. The force-fit and/or positive connection between the retaining element and the connecting element, i.e. the transition of the clamping mechanism from the released state to the clamped state additionally advantageously serves to secure the retaining element to the hardware element. For this purpose, the hardware element has a free space as a guide, in the form of a recess, a groove or a rail, in which the fastening element is or is movably guided or accommodated. The free space in the hardware element is configured in such a way that the retaining element can be displaced or guided along the longitudinal extension of the hardware element. Given the the hardware element or hardware elements of the corner fitting are aligned parallel to the front and/or rear surface of the door element, a shift occurs due to the displacement of the retaining element in the longitudinal direction of the hardware element of the door element with the hardware element in the opposite direction to the displacement of the retaining element in the longitudinal direction of the hardware element. It is thus possible, for example, to align the door element within a door frame along the longitudinal sides of the door frame and at the center of rotation and/or the axis.

According to the invention, the free space in at least one of the hardware elements is designed as a recess. In this case, the recess preferably extends in the longitudinal extent of the hardware element and particularly preferably in each case in the longitudinal extent of the two hardware elements, the recesses in the two hardware elements preferably being configured at the same height and in the same direction. parallel to each other. The free space known as a recess in the hardware elements is particularly preferably designed as a groove or gap and advantageously serves to guide the clamping element essentially parallel to the hardware elements and relative to its longitudinal extent. For this purpose, the retaining element has the upper part, which serves so that the retaining element is movably accommodated, at least in the released state of the fastening mechanism, in the recess of one or both of the hardware elements.

According to the invention, the clamping mechanism is configured in such a way that, in the separated state, a static friction acts between the clamping element and the recess, which is substantially less than the static friction acting in the clamped state between the clamping element and the recess. clamping element and notch. The clamping element and preferably at least two clamping elements serve to increase the static friction from the detached state to the clamping state of the clamping mechanism, by means of which the static friction between the recess and the clamping element can be adjusted. clamping. If, for example, the fastening element designed as a screw is screwed into the fastening element via the connecting element, the static friction between the fastening element and the recess is increased. Unscrewing the clamping element reduces the static friction between the clamping element and the recess and brings the clamping mechanism to the released state.

According to the invention, the static friction between the fastening element and the recess is increased to such an extent that the fastening element is fixed to at least one of the hardware elements by means of the fastening mechanism. In this case, a clamping between the clamping element and the recess acts in the clamping state, the clamping preventing a movement of the clamping element relative to the fitting element. With the clamping and fixed positioning of the clamping element in the clamping state of the clamping mechanism, the connecting element is also clamped in operative connection with the clamping element in its position relative to the hardware elements.

Against the background of a compact embodiment of the corner fitting according to the invention, with only little construction space being required, the clamping mechanism is configured in such a way that during the transition from the clamped state to the released state and vice versa the clamping element carries out a lifting movement within the free space. Since the fixing mechanism is integrated into the clamping element and the connecting element, it does not require additional components for the configuration of the fixing mechanism. In this regard, in particular, the free space configured as a recess in the hardware elements serves, in addition to the continuous guide of the retaining element in longitudinal extension with respect to the hardware elements, also to accommodate the retaining element in an at least clamped manner. clamping, and specifically in each position in the notch.

The retaining element is advantageously designed as an L-profile with an upper part and a connecting part, preferably in the form of two surfaces arranged essentially orthogonally with respect to one another, the upper part being accommodated in a free space configured as a groove, slit or notch. of the clamping mechanism movably and acting in the clamping state of the clamping mechanism by way of clamping in the notch. If both hardware elements each have a free space in the form of a groove, gap or notch, the upper part of the clamping element or the clamping element is advantageously designed as a T-profile for movably accommodating or clamping the clamping element in both notches of the hardware elements. By transferring the clamping mechanism from its released state to the clamping state, the clamping element configured as a T-profile offers on both sides, i.e. in the free spaces configured as a groove, gap or notch of the clamping elements hardware, at least in sections, a support surface, which serves for the force-fit and/or positive connection between the fastening element and the hardware elements. In this case, in the clamping state of the clamping mechanism, the upper part of the clamping element preferably acts as a clamping device in the two grooves, slits or notches. In contrast to the clamping element designed as an L-profile, the clamping element designed as a T-profile clamps evenly on both sides of the corner fitting, specifically on both fitting elements. As a result, in contrast to the clamping element configured as an L-profile, a more stable positive and/or positive-fit connection, i.e. a clamping, can be achieved with the clamping element configured as a T-profile. improved between the clamping element and the hardware elements. As already described for the clamping element configured as an L-profile, also in the case of the clamping element configured as a T-profile, the connecting element is connected to the clamping element via a connecting piece. through the fixing element.

In an embodiment not according to the invention, the connecting part and the upper part of the holding element are configured as a common, monolithic and/or one-piece component. Monolithic component is to be understood in this connection as a component produced, for example, by injection molding from one or more different components. A one-piece component can, however, also be understood as a component made of a material, which, for example, by processing a block of material, for example a metal block, is machined from the block of material, for example, by milling. A common component is preferably also to be understood in such a way that the upper part and the connecting part are configured as individual parts, which are provided as a common component, namely as a holding element in a pre-assembled state.

For adjusting the fastening mechanism, in particular for transferring the fastening mechanism from the released state to the fastening state and vice versa, the fastening element is preferably arranged in the fastening element in such a way that it is accessible to the user from the outside. Union. Since the connecting element is in operative connection with the fastening element, which is guided between the hardware elements and is thus difficult to access, via the externally operable fastening elements in the The connecting element can advantageously be adjusted from the clamping mechanism and in particular the clamping element from its clamped state, i.e. from the clamping with the free space configured as a notch, to the released state, i.e. to establish the capacity of continuous movement in longitudinal extension of the hardware elements or vice versa.

In order for the clamping element to be able to carry out a lifting movement via the fastening elements preferably arranged in a way that is accessible to the user from the outside in the connecting element, and to configure the fastening mechanism integrated in the connecting element fastening and in the connecting element, the fastening element has at least one hole, in which the fastening element is at least partially hooked in the fastened state, as a result of which an increased clamping between the fastening element and the notch. In the separated state, the fastening element preferably engages less in the borehole or is spaced away from the borehole, so that the clamping is less or the clamping is almost eliminated.

In order for the fastening element to be accessible from the outside in the connecting element, the connecting element has at least one through opening, in which the fastening element is arranged, the through opening extending in particular as far as the perforation. For the configuration of the fixing mechanism, which comprises a lifting movement of the holding element, the through opening is preferably not aligned in the separated state in line with the bore.

In order to move the perforation relative to the through opening, and thus give rise to a lifting movement of the holding element, according to the invention the perforation has means, which cause the connecting piece to move to the engage the fixing element in the hole perpendicular to the direction of movement of the fixing element. Decisive here for the size of the clamping element is the size of the engagement of the clamping element in the bore. In case the fixing element minus is hooked in the hole or in case the fixing element is separated from the hole, i.e. threaded towards the outside of the hole, the fixing element carries out a lifting movement in the direction perpendicular from the fastener and enters the separated state. For the clamping of the fastening element, the fastening element continues to be hooked in the perforation, being approximated through means, such as, for example, the configuration of the perforation with a beveled edge, which rises from the edge of the perforation towards the center of the hole, the clamping means perpendicular to the direction of movement of the fastening element towards the fastening element and reaching into the notch for clamping. Since the through openings are used to pass the fastening elements, and the fastening elements are advantageously screws, the through openings preferably have an internal thread, which is used for the force-fit connection and/or or positive with the fixing elements configured as screws. Because the hole or holes in the fastener are not aligned with the through openings in the connecting element and the holes are chamfered, for example to the outside, the fastener is displaced or rotated guided by the internal thread of the through opening along the beveled edge of the hole. Since, however, the internal thread of the through opening serves as a counter bearing for the clamping element, the clamping element moves along the chamfered edge, in particular perpendicular to the direction of rotation, by pushing the clamping element. movement of the fastener. In this case, the clamping element of the hardware element, guided by the free space designed as a notch, comes into forceful contact with the notch. In order to improve or guarantee the thrust of the fixing element along the medium configured as a beveled edge, the fixing element preferably has a conical surface in the front area, which engages with the perforation, which essentially corresponds to the slope of the beveled edge, i.e. it is adapted to the beveled edge.

Naturally, it is also conceivable that the bore itself has an internal thread for positive and/or form-fitting connection with the fastening element. The through opening in the connecting element can then optionally be designed as a hole with an internal thread or without an internal thread, through which the connecting element fastener is pushed in the direction of the hole in the fastener.

According to the invention, the clamping element is moved, by engaging the clamping element with the bore, perpendicular to the parallel guide. In the case of perpendicular movement of the fastening element, the latter is fixed via at least one catch section, which is formed on one of the surfaces of the fastening element, in at least one hardware element. In this case, the latching section of the retaining element is a section of a surface of the retaining element guided by the recess or by the free space, which is located on the upper part of the retaining element. If the positive and/or force-fit connection element is coupled to the retaining element according to the invention, the positive and/or force-fit coupling section is coupled to or in the recess. A displacement of the connecting element for aligning the door element in the center of rotation and/or the axis is therefore only possible by decoupling the force-fit connection between the fastening element and the hardware element . The force-fit connection decoupling of the retaining element from the hardware element in this case occurs, as already mentioned, through the separation of the force-fit and/or positive connection between the connecting element and the clamping element. Correspondingly, the force-fit coupling between the clamping element and the hardware element is eliminated, since the clamping element is pushed out or swiveled out of the hole and released by a movement perpendicular of the clamping element the clamping element from a clamping position to a releasing position. In order to then reconnect the fastening element in a force-fit connection to the hardware element, the fastening element has to be pushed back in the direction of the perforation. If the fastening element is pushed into the borehole, the fastening element is then moved in the perpendicular opposite direction, whereupon the latching section is then attached to the upper part of the fastening element in a force-fit connection with the fastening element. fitting and the fastening element being in its locking position.

Particularly preferably, the upper part has support surfaces on both sides, which preferably comprise the hook sections, which serve to guide the clamping element through both hardware elements and to enter from both sides, that is to say , with both hardware elements and in this case in particular in the recesses configured as free space of the hardware elements in contact in force and/or positive connection. In addition, support surfaces formed on both sides of the upper part of the fastening element have the advantage that the fastening element can be displaced not only parallel to the hardware elements, but also between the hardware elements, this it means, moving or moving towards one or the other hardware element. As a result, not only the corner fitting can be adjusted to the rear axis dimension of the center of rotation or the axis via the clamping element, but rather a plane displacement of the center of rotation or of the axis, this means a displacement of the door element clamped with the corner fitting towards, for example, a side part.

Furthermore, with the clamping element according to the invention, which is preferably configured as a clamping plate in the form of a T-profile, it can be adjusted by means of an inclined position of the clamping element between the hardware elements, for example, the door element around the center of rotation and/or the axis, namely aligning the door element with a certain angular range around the center of rotation or the axis.

In order to increase the clamping, i.e. the friction between the fastening element, and in particular between the latching section of the fastening element and the recesses formed in the hardware elements, the fastening element has in the area of the section preferably a surface with increased roughness and/or striation, for example in the form of a diamond pattern. In this case, the surface of the fastening section of the fastening element is advantageously designed in such a way that the clamping or friction between the fastening element and the hardware element ensures a positive, force-fit connection with respect to a surface. smooth, which collects or compensates for the torque present through the door closer in the corner fitting or in the door element. Naturally, it is also conceivable that the free space designed as a recess in the hardware element also has such a surface, which functions, for example, as a counter-holding means to the surfaces designed in the hook sections of the support surfaces of the hardware. fastening element.

Advantageously, the surface of the hook-in section of the upper part and/or of the free space configured as a notch in the hardware element 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 corrugated profile. An aperiodic profile can advantageously be formed by sanding or erosion. In this case, the underside of the upper part, which faces the connecting element, has the increased surface roughness at least in sections, particularly preferably in the region of the hook section.

In order to increase the force effect between the engagement section and the notch, the periodic profile advantageously extends transversely with respect to the longitudinal extension of the notch. As a result, the positioning of the clamping element in the hardware element can be advantageously adjusted by means of serrations. of the profile of the notch with the profile of the coupling section in enervating positions.

In order to be able to hold the fastening element in the fastening state of the fastening mechanism in a non-slip manner on the hardware element, the hook section and/or the recess have a surface with an increased anti-slip effect. As anti-slip material, it is preferable to apply a coating of polymeric material on the surfaces. Polymers are preferably used as polymeric material, such as, for example, structured copolymers from different monomers, such as polyester, polyurethanes and polyamides, or as homopolymers consisting of only one type of monomer, such as polyethylene, polypropylene, polyvinyl chloride and polyamide. , as well as polymer alloys resulting from the mixture of different polymers and copolymers.

The polymeric material is preferably an elastomeric material, such as, for example, thermosetting, thermosetting, elastomeric or thermoplastic elastomeric plastics.

In the present application the following concepts are to be understood as follows, but this understanding of the concepts is not to be regarded as limiting.

By "fastening element" is to be understood a component that is movable essentially parallel to the hardware elements, i.e. displaceable, and advantageously also a rotatable one, which serves to displace the connecting element operatively connected to the fastening element in parallel to the hardware elements and align the hardware with a door element held in the clamping area around a center of rotation and/or an axis. In this connection, the retaining element can be designed as a single-surface or multi-surface body. Naturally, the retaining element can also be configured from one or more interconnected crossbars or in another way, for example as a corner piece. The type and construction of the fastening element is limited only by the free space that is available between the hardware elements, which is formed by the separation of the hardware elements from one another. Advantageously, the retaining element is designed as a T-profile made of plastic material, metal, in particular steel, stainless steel, aluminum or an aluminum alloy, or from a metal-coated plastic material by materials engineering. In contrast, the hardware elements are advantageously designed as die-cast hardware made of aluminum.

By "connecting element" is to be understood a component that houses the center of rotation and/or the axis. To increase the variability of the connecting element, this housing can have different sizes or can be adapted to housings with different sizes by means of, for example, adapter inserts. The connecting element can be a separate component, which is brought into operative connection with the retaining element via fastening elements.

"Free space, which is configured as a recess in at least one hardware element," can be understood as free space in the form of grooves, grooves, grooves, recesses, rails, projections, indentations and/or, for example, bands of rolling, which allows a movable, that is to say, mobile housing of the fastening element. Naturally, retaining means can be formed along the free space, which enable the retaining element to be hooked and thus a pre-adjustment of the door element to predetermined rotational center dimensions and/or axis dimensions. However, only clamping and/or stop points can be configured for centers of rotation and/or standardized axes. In this connection, a continuous sliding ability of the retaining element in the free space is advantageously ensured between two retaining means or between two hooking and/or holding points, as a result of which a fine adjustment of the mounting hardware can be carried out. corner to non-standard centers of rotation.

If the cut-out is formed in the form of grooves, grooves, recesses and/or projections, the retaining element hooking section or the retaining element hooking sections advantageously have a groove, grooves, grooves, grooves, recesses or protrusions, which engage grooves, serrations, grooves, recesses and protrusions of the notch positively.

In order to increase the positive and/or positive-fit connection between the clamping element 1 configured as a T-profile with the hardware elements 40 and 50, the contact surfaces 5 have catch sections 6, which are profiled as a striation in the form of a rhombus pattern. The striation can, however, also be configured as a cross striation or as a parallel striation. In this connection, the striation can be oriented in all directions, in which bearing surfaces 5 are formed.

In FIG. 2, the retaining element 1 is configured as a flat molded body, which comprises only one connecting piece 1.2. In order to move the flat molded body, in particular the clamping element 1 shown in connection with the hardware elements 40 and 50 and to fix it via clamping elements 100 to the hardware elements 40 and 50, a recess 4 in the form of an elongated hole. Although the position of the fastening elements 100 is fixed to the hardware elements 40 and 50, the fastening element 1 can thus be displaced through the recess 4 configured as an elongated hole when the fastening elements 100 are passed through. of the elongated hole at least in some areas parallel to the hardware elements 40 and 50, in particular parallel to the contact sections 60 of the hardware elements 40 and 50. In this respect, they limit the displacement of the hardware element. fastening 1 and the fastening of the fastening element 1 via the fastening elements 100 guided through the cutout 4, both the arrangement of the fastening elements 100 on the hardware elements 40 and 50, as well as the size of the notch 4.

Just as the clamping element 1 shown in Fig. 1, which is designed in the form of a T-profile as a clamping plate, the flat clamping element 1, shown in Fig. 2, can also be connected to a clamping element. connection 90 or be configured as a common, monolithic and/or one-piece component with the connection element 90, the connection element 90 preferably having a receptacle 130, for example, for a shaft body of a pivot shaft .

In Fig. 3 the fastening element 1 shown in Fig. 1 is represented in a front view. To the rib 2 of the connecting piece 1.2 is attached the pin 3 in the downward direction, via which the clamping element 1 is connected to the connecting element 90. Orthogonally to the connecting piece 1.2, this that is to say, in the present case also orthogonal to the pin 3, which is preferably contained by the connecting part 1.2, the upper part 1.1 is formed. In this connection, the upper part 1.1 protrudes on both sides with the support surfaces 5 of the connecting part 1.2. For a better clamping, this means for the increase of the positive and/or force-fit connection between the clamping element 1, in this case in particular between the support surfaces 5 and the recesses 110 formed in the hardware elements. 40 and 50, the support surfaces 5 each have a catch section 6. The catch section 6 is in the present case designed as a groove.

Fig. 4 shows the holding element 1 of figures 1 and 3 in a top view from the underside. As can be clearly seen in this view, the connecting piece 1.2 widens at the end regions configured as pins 3. In other words, the rib 2 of the connecting piece 1.2 narrows with respect to the pins 3 configured by the end sides. As a result, a friction between the hardware elements and the connecting piece can be reduced, as a result of which the displaceability of the clamping element 1 in the state released from the clamping mechanism is advantageously facilitated. As shown, the hooking section 6 is configured as a diamond-shaped groove along the entire length of the bearing surface 5 of the fastening element 1.

Fig. 5 shows a door element 30, which is supported by a corner fitting 10 at a center of rotation 20, which can also be, for example, an axis BTS. The corner fitting 10 is clamped under the lower left corner of the door element 30. The corner fitting 10 shown in FIG. 5 is designed in such a way that it could also be clamped in the upper left or upper right or lower right corner. of the door element 30 for receiving the door element 30 at the center of rotation 20 and/or an axis. The corner fitting 10 consists of a first fitting element 40 and a second fitting element 50. Both fitting elements 40 and 50 have contact sections 60, which serve at least for direct contact via an intermediate layer for contact with the door element 30. Between the hardware elements 40 and 50, a holding area 70 is formed, in which the door element 30 can be arranged. The hardware elements 40 and 50 are designed in such a way that between Arranged on both hardware elements 40 and 50 is a retaining element 1, which can be displaced relative to the hardware elements 40 and 50, in particular in the longitudinal extent of the hardware elements 40 and 50. For receiving the element of door 30 at the center of rotation 20 and/or the axis serves a connecting element 90 operatively connected with the holding element 1. The connecting element 90 is operatively connected in the present case through two s fastening elements 100 in positive and/or force-fit connection with the holding element 1. The holding element 1 in operative connection with the connecting element 90 is in each case movably guided by a free space 110 configured as a notch in the form of a groove, in the hardware element 40 and the hardware element 50. In this case, the free space 110 is configured in the form of the groove parallel to the longitudinal extension of the hardware elements 40 and 50. As a result, the clamping element 1 and the connecting element 90 in operative connection via the fastening elements 100 are parallel along the free space 110, i.e. displaceable towards or in the longitudinal direction of the hardware elements 40. and 50. Since the connecting element 90 with the holding element 1 can be displaced relative to the door element 30 in the opposite direction, the door element 30 can be aligned on the center of r otation 20 along the axis BB, for example, in its position in a door frame or glass door installation continuously. In the event that, for example, the center of rotation 20 or the axis of rotation of the door element 30, which is represented by the axis AA, is outside the areas set for the usual centers of rotation 20, specifically outside 55 mm , 65 mm or 70 mm, the door element 30 can be adjusted by displacement of the clamping element 1 and thereby with the connecting element 90 operatively connected with the clamping element 1 at the center of rotation and/or the axis. The fastening element 1 and the connecting element 90 are configured in the present case as two interconnected construction components, which comprise the fastening mechanism, which is integrated in the present case in both construction components, namely in the fastening element 1 and the connecting element 90 and which can be brought through the fastening elements 100 from the fastening state to the released state and vice versa. To transfer the fastening mechanism from the released state, in which the fastening element 1 can be displaced along the longitudinal extension of the hardware element 40 and 50 in the free space 110 configured as a notch, into the fastened state, they are screwed to This means the fastening elements 100, which connect the fastening element 1 through the connecting piece 1.2 with the connecting element 90 in the through openings 120. When the fastening elements 100 are screwed into the connecting piece 1.2 of the element clamping element 1, the upper part 1.1 of the clamping element 1 is clamped, at least in sections, in a force-fit connection in the free space 110, which is configured as a notch in the form of a groove or a slit, next to the hardware elements 40 and 50. In the clamping state of the clamping mechanism, the ability to move of the clamping element 1 and the connecting element 90 operatively connected with clamping element 1 or clamping element 1 is fastened to hardware elements 40 and 50.

Fig. 6 shows the hardware element 50, the fastening element 1 and the connecting element 90 in the unassembled state. As can be seen, the contact section 60 is configured only in sections. The contact section 60 follows in particular the contour of the cut-off corner area of the door element 30, as shown in Fig. 5. For positive and/or force-fit connection between the connecting element 90 and The fastening element 1 serves fastening elements 100, which are not shown here. The fastening elements 100 are guided or screwed through through openings 120 in the form of bores formed in the connecting element 90, which are advantageously formed in the form of internal threaded bores, in which the force-fit connection is engaged. and positive the fixing element 100 configured as a screw. Together with the fastening elements 100, the connecting element 90 and the fastening element 1 form the fastening mechanism, which can be brought from a displaceable mounting of the fastening element 1 in a released state into a fastened state, in which which the fastening element 1 is at least positively coupled with the hardware element 50 and one hardware element 40 shown in FIG. 5. In the state of the positive-fit coupling of the fastening element 1 to the The fitting element 40 and/or 50 can be fixed by an alignment or adjustment of the corner fitting carried out previously, on the axis or the center of rotation 20.

The connecting element 90 operatively connected to the retaining element 1 has a recess 130 approximately centrally, which serves to position the door element 30 at the center of rotation 20 and/or the axis. In this respect, the housing 130 can advantageously be adapted to the center of rotation 20 and/or the axis, for example by means of different adapters. Since the connecting element 90 is in the present exemplary embodiment an individual component of the corner fitting 10, it can of course also be connected to receptacles 130 of different sizes in a variable manner with the retaining element 1 and form the fastening mechanism. For the connection of the retaining element 1 with the connecting element 90, recesses 140 are formed in the connecting element 90 in the area of the through openings 120, which serve to receive pins 3 formed in the retaining element 1. , which are advantageously formed in the connecting part 1.2 of the holding element 1. The pins 3 each have a hole 4, through which the fixing elements 100 are hooked, which are guided through the through openings 120. Fastening elements 100 preferably serve here to bring the fastening mechanism, which is formed, inter alia, from the connecting element 90 and the retaining element 1, into different operating states. On the other hand, via the fastening elements 100, the connecting element 90 and the retaining element 1 are connected in a forceful and positive connection and thus form a pre-assembled one-piece component. The support surface 5 formed on the upper part 1.1 of the retaining element 1 is guided in the hardware element 5 by the free space 110 formed as a notch in the form of a slot.
