ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a mounting for a door leaf, a fanlight leaf or the like, particularly for an all-glass leaf, having a plane clamping plate and a plane counter clamping plate, which, in the region of an edge recess of the leaf in a leaf edge of the leaf, can be attached to the leaf at the two opposite surfaces, and the leaf can be pinched between the clamping plate and the counter clamping plate by means of fastening screws joining the clamping plate and the counter clamping plate.
For example from the DE-OS 24 32 961 it is known a mounting for an all-glass door comprising a clamping plate and a counter clamping plate, between which the door leaf can be pinched in the region of an edge recess. At the clamping plate a lateral extension is formed, which engages in the edge recess. Moreover, the clamping plate and the counter clamping plate comprise a recess open in direction towards the edge face of the door leaf, in which recess an insert assembly is fixed having an opening for receiving a pin, for example, when the door leaf mounting is used as a bottom mounting, an essentially rectangular opening for receiving a pin of a door closing mechanism the pin being rectangular in its cross section.
On the other hand from the DE-GM 94 20 766 a door leaf mounting is known, which is formed as a casting part and which is formed with a web plate extending perpendicular to the clamping plate, at the free edge of the clamping plate. At the outer surface of the web plate a door closing mechanism bearing pin having a rectangular cross section is mounted by means of a fastening screws This door leaf mounting can also be used for door leafs, which do not comprise a recess, but only comprise bores for fastening screws extending through it, wherein the web plate embraces the door leaf edge. The clamping plates comprise parts protruding laterally from the plate plane and having bores for receiving fastening screws.
SUMMARY OF THE INVENTION
It is an object of the invention, to provide a mounting of the above mentioned type, which can be manufactured easily. Preferably the mounting according to the invention is to be adaptable to differently shaped edge recesses and is to be usable as an alternate mounting which fits for the application at all sides of the door.
The mounting according to the invention for a door leaf, a fanlight leaf or the like, particularly for an all-glass leaf, is provided with a plane clamping plate and a plane counter clamping plate, which, in the region of an edge recess of the leaf in a leaf edge of the leaf, can be attached to the leaf at the two opposite surfaces, wherein the leaf can be pinched between the clamping plate and the counter clamping plate by means of fastening screws joining the clamping plate and the counter clamping plate. At the clamping plate a web plate is formed extending perpendicular to the clamping plate, which web plate, in the assembled condition, extending through the edge recess, spans over the distance between the clamping plate and the counter clamping plate. The counter clamping plate is provided with a rectangular recess being adapted to the free end of the web plate, the web plate in the assembled condition engaging with its free end in the rectangular recess. According to the invention the clamping plate inclusive of the web plate and the counter clamping plate are formed as sections cut from extruded profile rails or rolled profile rails.
According to a preferred embodiment of the invention the web plate with its outer surface is flush to that clamping plate edge face which is adjacent to the web plate, and does not extend over said clamping plate edge face. In this case the web plate is provided with an opening defining an axis extending in a direction parallel to the plane defined by the clamping plate.
It is another preferred embodiment according to the invention, that the web plate is arranged at the clamping plate in such a way that its outer surface is misaligned to the clamping plate edge face, and that the clamping plate comprises an open fitting recess extending from the clamping plate edge face to the web plate. Into the fitting recess an insert plate is inserted, which is supported at the web plate. The insert plate is provided with an opening defining an axis extending in a direction parallel to the plane defined by the clamping plate. The insert plate can be a steel plate or a plate of a high strength aluminium based alloy or a plate of another metal or a ceramic material. According to the invention the web plate also can be provided with an opening being in alignment with the opening in the insert plate.
It is particularly advantageous that according to the invention the clamping plate inclusive of the web plate, the counter clamping plate and the insert plate are formed as an extrusion profile rail or a rolling profile rail, which do not comprise any protrusions extending laterally with respect to the extrusion or rolling direction, respectively, as, for example, bearing parts with bores for fastening screws or the like. As a result the respective plate parts can be cut off from the profile rails into sections of any appropriate length.
According to a preferred embodiment of the invention the opening in the web plate and in the insert plate, respectively, is formed as an elongated hole extending in parallel to the clamping plate. As a result, the possibility for an adjustment is provided, particularly in connection with the reception of other components, for example a bearing pin, so that the bearing pin can be inserted in such a way, that it comes exactly into engagement with an opposing receiver opening, for example with a bearing bush. It is also possible to form the opening in a circular shape and to provide thereby, for example, the possibility to insert and to press in, respectively, a circular bearing bush. Such a mounting having a bearing bush pressed in can be used for a leaf of a fixed fanlight, which is adjacent to a pivotable door leaf.
According to a preferred embodiment of the invention, if the mounting is to be provided with a pivotation pin, this pivotation pin can be provided with a widened head, which is formed in a shape corresponding to the elongated hole, so that the pivotation pin can be fitted to the elongated hole of the web plate. By means of a fastening screw and a washer plate adjacent to the inner surface of the web plate, that is the surface of the web plate which is facing the edge recess, the pivotation pin can be fixed and can be supported at the inner surface of the web plate.
According to a preferred embodiment of the invention the center of the opening in the web plate and/or in the insert plate is arranged in the center in the longitudinal direction of the clamping plate, wherein preferably the web plate or the web plate and the insert plate, respectively, inclusive of the opening is formed symmetric relative to the center in the longitudinal direction of the clamping plate. In this case the clamping plate inclusive of the web plate can be manufactured of an L-profile rail or a T-profile rail, respectively, such that in the leg of the L-profile or in the web of the T-profile, respectively, which forms the web plate, parts are removed by punching them out or cutting them off in the respective regions, particularly at the both lateral ends of the web plate. Just as well the fitting recess can be formed by punching out or cutting off material in an appropriate region of the profile part. The opening in the web plate also can be formed as a punched out opening.
According to a preferred embodiment of the invention, a longitudinal groove having an undercut is formed at a surface which is in the assembled condition the outer surface of the clamping plate and/or at a respective surface of the counter clamping plate, the longitudinal groove extending along the clamping plate and/or the counter clamping plate, respectively, and being open to its both ends. The longitudinal groove can have, for example, a dovetail shaped or a T-shaped cross section, wherein T-shap
