Description

Mounting element for fastening fittings, in particular band parts on a frame or on a wing

The invention relates to a mounting element for fastening fitting parts, in particular of hinge parts on a frame or on a wing, with a fastened to the frame or on the wing attachment part.

From DE 202 18 699 U1 a device for fastening fitting parts to a multi-chamber profile of a frame or a wing is known. It has a mounting screw and a fastening screw, wherein the mounting screw comprises an external thread of a length which passes through a plurality of walls of the hollow chamber profile with screwed mounting screw. At the rear end in the direction of insertion, the mounting screw has a collateral collar. Further, an internal thread is provided at the rear end into which the fastening screw can be screwed. To attach a fitting part, the fastening screw is screwed into the hollow chamber profile until the contact point rests against the outer profile wall. Subsequently, the fitting part, which must have a centering bore adapted to the outer circumference of the bearing collar, is put on and fixed by screwing in the fastening screw into the internal thread.

Although this device ensures a secure attachment of the fitting part even with hollow section profile having frames or wings, since holding forces are introduced into a plurality of profile walls, the disadvantage is that it is for adjusting the fitting perpendicular to the mounting surface on the frame or on the wing additional Requires action on the fitting part, whereby the manufacturing costs associated with the fitting part is increased.

The invention is therefore an object of the invention to provide a mounting member for fastening fittings, in particular of hinge parts on a frame or on a wing, by means of which on the one hand a secure attachment of the fitting part is ensured on the frame or the wing, on the other hand, a simple adjustment of Fitting part on the frame or the wing is possible. This object is achieved by the reproduced in claim 1 mounting element.

Characterized in that on the fastening part of the mounting member rotatable about its central longitudinal axis and fixed in the direction of the longitudinal central axis threaded extension is provided, the fitting requires only a threaded extension complementary shaped threaded bore into which the threaded extension after mounting the fastening part to the frame or the wing is rotatable. The adjustment of the fitting perpendicular to the mounting surface can then be done by the threaded extension is rotated until the fitting has assumed the desired position.

This solution, which is technically easy to implement, is based on the surprising knowledge that it is not necessary for a permanent seat of fitting parts, in particular of hinge parts on the frame or the wing, to rest against the fastening surface of the frame or the wing. The frictional forces generated by the holding forces between the threads of the threaded bore in the fitting part and the threads of the threaded extension prevent the threaded extension from turning automatically, which would result in misalignment of the fitting part.

The threaded extension can in principle be configured constructively in any desired manner, for example as a threaded head, which is attached to the fastening part via a riveted connection. However, an embodiment in which the thread extension comprises a suitably mounted threaded sleeve so that it can accommodate particularly high holding forces is particularly preferred.

The bearing of the threaded sleeve then preferably serves a bearing extension provided on the fastening part.

On additional bearing elements between the bearing extension and the threaded sleeve can be omitted if the bearing extension a circular outer cross-section and the threaded sleeve has a circular inner cross section adapted to the diameter of the outer cross section.

The fixation of the threaded extension in the axial direction, i. In the direction of its center longitudinal axis can in turn be constructively in any way, for example by means of a threaded sleeve centrally passing, engaging in the bearing extension rivet be accomplished. However, it is particularly preferred to provide a region between the fastening part and the bearing extension, which has a diameter which is smaller than the diameter of the bearing extension. This area can be designed as an annular groove.

In this area then preferably protrudes provided on the threaded sleeve, inwardly directed collar. Experiments have shown that in this embodiment, on the one hand the threaded sleeve in the axial direction on the bearing extension has a sufficiently strong anchoring, on the other hand anchoring can be effected in a technically simple manner, namely by the jacket of the threaded sleeve after pushing the same by means of a suitable crimping in the Area is pressed into it.

In a first, preferred variant of the mounting element according to the invention, the fastening part has a fastening extension.

This attachment extension is preferably provided with an external thread which is self-tapping. The mounting element is then suitable, for example, for an adjustable attachment of a fitting part to a hollow-chamber profile of a frame or a wing if the external thread has a length such that it engages in a plurality of walls of the hollow-chamber profile.

Particularly preferred is a development in which the fastening projection comprises a drill neck at its free end. This embodiment is particularly preferred when the mounting member is provided for adjustable attachment of fittings to solid frame, such as wood or thick-walled profiles made of plastic or metal. Especially for thick-walled metal profiles, in which then a complementary threaded hole must be incorporated in advance, the mounting element according to the invention is suitable when the external thread is a machine thread, for example, a metric thread.

In principle, the attachment extension can be designed in any desired way, which ensures a sufficiently tight fit for introducing the holding forces into the frame or the wing. For mounting on a hollow profile, the extension may in particular rivet-like or be designed as a spreading element, which latter variant is also suitable for fixing the fastening extension in a hole in a solid frame or wing.

In a further, constructive variant of the mounting element according to the invention, the fastening part comprises a fastening piece which - as known from the prior art - inserted into a chamber of a hollow profile or inserted into a recess of a solid frame or wing and fixed there.
