Abstract

A corner fitting for a door element, in particular for a glass door element, includes a first fitting element and a second fitting element, which each include, at least sectionwise, a locating portion. The locating portion includes an intermediate layer able to contact the door element. The fitting elements delimit the restraining area, wherein a holding element is in operative connection with a connecting element, which serves for supporting the door element on a center of rotation and/or an axis.
At least one variably adjustable distancing element is disposed between the fitting elements outside the locating portions, wherein the distancing element forms a counter-bearing to the locating portions and the door element, which can be restrained in the restraining area.

First claim

The invention claimed is:

1. A corner fitting for a door element, comprising a first fitting element and a second fitting element, wherein each of the fitting elements includes, at least sectionwise, a locating portion, which comprises an intermediate layer configured to contact the door element, and the fitting elements delimit a restraining area, wherein a holding element includes at least one connecting part and is interconnected to a connecting element and is movable in a recess disposed in the fitting elements such that the door element is aligned on a center of rotation and/or an axis, the connecting element includes a plurality of apertures configured for receiving the at least one connecting part,
wherein at least one distancing element is disposed between the fitting elements and separate from the locating portions, wherein the distancing element forms a counter-bearing to the locating portions and to the door element, which can be restrained in the restraining area.

2. The corner fitting according to claim 1 ,
wherein the distancing element has a variable adjustable length extending from at least one longitudinal axis of the fitting elements.

3. The corner fitting according to claim 1 ,
wherein the distancing element includes a threaded means, by means of which a variable adjustable length extends from at least one longitudinal axis of the fitting elements.

4. The corner fitting according to claim 1 ,
wherein the fitting elements include a mount separate from the locating portions and at which the distancing element is disposed.

5. The corner fitting according to claim 4 ,
wherein the mount includes a reception, into which the distancing element extends.

6. The corner fitting according to claim 4 ,
wherein the fitting elements are each embodied with a lower recess, in which the connecting element is displaceable, wherein a bottom area is configured as a free space between the fitting elements, and the distancing element is located at approximately the same height as that of the lower recess.

7. The corner fitting according to claim 4 ,
wherein said at least one distancing element and a second distancing element, which extend almost parallel to each other and are separate from the locating portions and which form the counter-bearing to the locating portions and to the door element restrained in the restraining area.

8. The corner fitting according to claim 7 ,
wherein each of the distancing elements, at least via one of their ends, is positively detachably connected in the mount, which is configured at the fitting element.

9. The corner fitting according to claim 4 ,
wherein the mount includes a bore with an internal thread adapted to an external thread of the distancing element and in which the distancing element is screwable and/or from which it is unscrewable.

10. The corner fitting according to claim 1 ,
wherein an attaching mechanism is incorporated at least at the holding element as well as at least at the connecting element, which mechanism is transferable between a released condition and a fixing condition, wherein, in the released condition, the holding element is displaceable at the fitting elements, and in the fixing condition it is fixedly attached to at least one fitting element.

11. The corner fitting according to claim 1 ,
wherein the recess extends along the longitudinal extension at least of one fitting element, and the holding element is supported to be movable with a head part in the recess, wherein, in the fixing condition, the holding element with a resting portion, which as an engagement portion is located at the head part, abuts against the recess.

12. The corner fitting according to claim 10 ,
wherein the attaching mechanism is configured such that during the transfer from the fixing condition into the released condition and from the released condition into the fixing condition, the holding element performs a stroke movement within a free space between the fitting elements.

13. The corner fitting according to claim 11 ,
wherein the connecting element is attached via the attaching mechanism, wherein the head part and the connecting part are aligned vertically to each other.

14. A method for adjusting a corner fitting for a door element, for accommodating different material thicknesses of the door element in the corner fitting, including a first fitting element and a second fitting element, which, each at least sectionwise, include a locating portion, which comprises an intermediate layer able to contact the door element, and the fitting elements delimit the restraining area, wherein a holding element having at least one connecting part is interconnected to a connecting element and is movable in a recess disposed in the fitting elements such that the door element is aligned on a center of rotation and/or an axis, the connecting element having a plurality of apertures configured for receiving the at least one connecting part, at least one distancing element being disposed between the fitting elements and separate from the locating portions, wherein the distancing element forms a counter-bearing to the locating portions and to the door element, which can be restrained in the restraining area, including the following steps:
1) dismounting the fitting elements,
2) adjusting the length of the distancing element extending from at least one of the fitting elements, and
3) mounting the fitting elements.
