DETAILED DESCRIPTION OF DRAWINGS

(8) FIG. 1 shows a door element 3, which, via a corner fitting 1, is supported on a center of rotation 2, which may be for example also a BTS-axis. At the lower left corner of the door element 3, the corner fitting 1 is clamped to the door element 3 via locating portions 6. The corner fitting 1 illustrated in FIG. 1 is configured such as to be also clampable to the top left or the top right or the lower right corner of the door element 3 for supporting the door element 3 on a center of rotation 2 and/or an axis. The corner fitting 1 consists of a first fitting element 4 and of a second fitting element 5. Both fitting elements 4 and 5 include locating portions 6, which serve at least for indirect abutment via an intermediate layer, not illustrated here, against the door element 3. A restraining area 7, into which the door element 3 is insertable, is formed between the fitting elements 4 and 5. A holding element 8, which is displaceable in relation to the fitting elements 4 and 5, in particular in longitudinal extension of the fitting elements 4 and 5, is disposed between the two fitting elements 4 and 5. A connecting element 9, which is operatively connected to the holding element 8, serves for supporting the door element 3 on the center of rotation 2 and/or the axis. In the present case, the connecting element 9 is non-positively and/or positively operatively connected to the holding element 8 via two attaching elements 10. The holding element 8 being in operative connection with the connecting element 9 is guided to be movable in the fitting element 4 and the fitting element 5 in a free space 11 configured as a recess 11.1 in the shape of a groove. In this case, the free space 11 is configured in the shape of a groove parallel to the longitudinal extension of the fitting elements 4 and 5. The holding element 8 and the connecting element 9, which is in operative connection via the attaching elements 10, are thereby displaceable parallel along the recess 11.1, i.e. with regard to, respectively in the longitudinal extension of the attaching elements 10. As the connecting element 9 with the holding element 8 is displaceable in relation to the door element 3 in the opposite direction, the door element 3 can be infinitely variably aligned on the center of rotation 2 along the axis BB, for example in its position in a door frame or a glass door installation. In the event e.g. the center of rotation 2, respectively the axis of rotation of the door element 3, represented by the axis AA, is located outside the areas determined for the usual centers of rotation 2, namely outside of 55 mm, 65 mm or 70 mm, the door element 3 may be aligned on the center of rotation and/or the axis by displacing the holding element 8 and thereby with the connecting element 9, which is operatively connected to the holding element 8. In the present case, the holding element 8 and the connecting element 9 are configured as two interconnected structural components comprising the attaching mechanism, which in the present case, is incorporated into both structural components, namely the holding element 8 and the connecting element 9. For transferring the attaching mechanism form the released condition, in which the holding element 8 is supported to be movable in the longitudinal extension of the fitting elements 4 and 5, into the fixing condition, the attaching elements 10, which connect the holding element 8 via the connecting part to the connecting element 9, are screwed into the through-holes 12. When screwing the attaching elements 10 into the connecting part 8.2, the holding element 8 performs a stroke movement, and gets clamped via a resting portion 16 at least sectionwise at least non-positively in the free space 11, configured as a recess 11.1 in the form of a groove, at the fitting elements. Thus, in the fixing condition of the attaching mechanism, the displaceability of the holding element 8 and of the connecting element 9 operatively connected to the holding element 8 is disabled, respectively the holding element 8 is immobilized in its position at the fitting elements 4 and 5.

(9) With the intention to assist the infinitely variable displacement of the holding element 8 in longitudinal extension of the fitting elements 4 and 5, which holding element is connected to the connecting element 9 via the connecting part 8.2, a lower recess 18 is configured at the fitting elements 4 and 5, which is preferably formed parallel to the recess 11.1 formed as the free space 11 and preferably extends over the same length as the recess 11.1 configured as the free space 11. Preferably in this case, the lower recess 18 is formed in both fitting elements 4 and 5 and extends over the distance 17 of the fitting elements from the one to the other fitting element 4 and 5.

(10) For a better illustration of the support of the holding element 8 in the corner fitting 1, FIG. 2 shows the corner fitting 1 without the front fitting element 4 in the non-mounted condition. As can be seen, outside the locating portion 6, the door element 3 includes a cutout according to the known glass cutout standards and, outside the cutout, bears against the locating portion 6 of the fitting element 5. A free space, which serves for disposing the holding element 8 and the connecting element 9, is created in the corner fitting 1 in the area of the cutout of the door element 3. As can be additionally seen in FIG. 2, the attaching mechanism just comprises the holding element 8 and the connecting element 9, which are non-positively and/or positively interconnected via two attaching elements 10 (not illustrated here), which can be manipulated through the through-holes 12 configured at the connecting element 9. The attaching elements 10, which are advantageously configured as screws or headless screws, pass through, respectively are screwed into the through-holes 12 in the shape of bores, which are configured in the connecting element 9. Together with the attaching elements 10 and the free space 11, the connecting element 9 and the holding element 8 form the attaching mechanism, which is transferable from an infinitely variably displaceable support of the holding element 8 in a released condition into a fixing condition, in which the holding element 8 is at least non-positively coupled to the fitting element. In the non-positive coupling of the holding element 8 to the fitting element 4 and/or 5, a positioning of the door element 3 can be indirectly immobilized via the alignment of the corner fitting 1 on the axis or the center of rotation. For this purpose, the connecting element 9, which is operatively connected to the holding element 8, has a reception 13 almost in the center, which serves for disposing the door element 3 on the center of rotation 2 and/or the axis. Advantageously in this case, the reception 13 is adaptable to the center of rotation 2 and/or the axis, for example by means of different adapters. As, in the present exemplary embodiment, the connecting element 9 is a single component of the corner fitting, with differently large dimensioned receptions 13, it may obviously be variably connected to the holding element 8 and thus comprise the attaching mechanism. For connecting the holding element 8 to the connecting element 9, the connecting element 9 has apertures 14 configured in the area of the through-holes 12, which serve for accommodating tappets 15, which are configured at the holding element 8 and are formed at the connecting part 8.2 of the holding element 8. The tappets 15 have respectively one bore 15.1, through which the attaching elements 10 engage, which are guided in the through-holes 12 of the connecting element 9. Preferably, the attaching elements 10 serve in this case for transferring the attaching mechanism, which is formed among others from the connecting element 9 and the holding element 8, into different functional conditions. On the other hand, the connecting element 9 and the holding element 8 are non-positively and/or positively connected via the attaching elements 10 and thereby form a pre-mounted integral structural component. The surface configured at the head part 8.1 of the holding element 8 is guided in the fitting element 5 in the free space 11 configured as a recess 11.1 in the shape of a groove. As can be seen, the bores 15.1 in the tappets 15 of the holding element 8 include respective means, in the present case in the shape of a chamfer, which serve for reducing respectively for increasing the bores 15.1. The function of the means 15.2 is illustrated in the FIGS. 4a and 4b.

(11) In a top view, FIGS. 3a and 3b show the underside of the head part 8.1 of the holding element 8 configured as a clamping part with an engaging, respectively resting portion 16. For increasing the clamping, i.e. the friction between the holding element, in particular between the engaging, respectively resting portion 16 and the recess 11, the engaging, respectively resting portion 16 includes a ribbing for example as illustrated in FIG. 3a a diamond-shaped ribbing. Another embodiment of the ribbing of the engaging, respectively resting portion 16 is shown in FIG. 3b, wherein a parallel ribbing is configured at the engaging, respectively resting portion 16, which is configured vertically to the longitudinal extension of the free space 11 configured as the recess 11.1. Obviously, the clamping of the holding element 8 configured as the clamping plate may just be realized via a non-positive connection, which however, is limited to a maximum torque transferred from the floor door closer onto the holding element 8 via the axis of rotation.

(12) In a diagrammatical sectional view, FIGS. 4a and 4b show the holding element 8, which is configured in a T-shape as a T-profile. FIG. 4a shows in this case, the holding element 8, which in the released condition is freely displaceable, and FIG. 4b shows the holding element 8, which in the clamped position, respectively in the fixing condition is non-positively connected to the free space 11 configured as a recess 11.1 of the fitting element 4 and 5. The non-positive connection between the holding element 8 and the free space 11 configured as a recess 11.1 of the fitting element 4 and 5 is realized via the advance of the attaching element 10. As illustrated in FIG. 4b, the attaching element 10 is advanced in the direction of the bore 15.1, wherein the cone surface 15.1 configured at the attaching element 10 pushes against the means 15.2 configured as a chamfer in the bore 15.1, whereby the holding element 8 is pulled downwards, i.e. performs a stroke movement in vertical movement to the movement of the attaching element 10 and in orthogonal direction to the longitudinal extension of the fitting elements 4 and 5. The engagement of the attaching element 10, as illustrated here by means of the cone surface 15.1 running along the means 15.2 configured as a chamfer, realizes the non-positive and/or positive connection between the connecting element 9 and the holding element 8 and thereby realizes directly a non-positive and/or positive connection of the holding element 8, via the engaging, respectively resting portion 16, to the fitting element 4 and 5, and namely in particular by means of the stroke movement of the holding element vertically to the longitudinal extension of the fitting elements 4 and 5 and vertically towards the attaching element 10, i.e. along the axis AA illustrated in FIG. 1 as far as to the abutment of the engaging, respectively resting portion 16 against the resting surface configured by the free space 11.
