FITTING

A fitting, in particular a fitting for furniture, includes perforations for screwing the fitting to a component. Self-tapping screws are premounted on the fitting and inserted and retained in the perforations in such a way that screw tips of the screws protruding from the fitting can be inserted into bores of the component.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority, under 35 U.S.C. § 119, of German Patent Application DE 20 2021 003 572.9, filed Nov. 22, 2021; the prior application is herewith incorporated by reference in its entirety.

FIELD AND BACKGROUND OF THE INVENTION

The invention relates to a fitting, in particular for furniture, having perforations for screwing the fitting to a component.

Items of furniture are frequently delivered in a disassembled state to an end user who then has to finish building the item of furniture. A large number of fittings, for example guide rails for drawers or the like, are generally required to do that. Various screws, which generally have to be painstakingly picked out from a lot of small parts, are required to fasten the fittings to parts of items of furniture. It is often found in that case that there are not enough of the screws that are needed or that they are missing altogether.

SUMMARY OF THE INVENTION

It is accordingly an object of the invention to provide a fitting, which overcomes the hereinafore-mentioned disadvantages of the heretofore-known fittings of this general type.

With the foregoing and other objects in view there is provided, in accordance with the invention, a fitting, in particular for furniture, having perforations for screwing it to a component, and self-tapping screws being inserted and retained, premounted, in the perforations in such a way that the screw tips, protruding from the fitting, can be inserted into bores of the component.

In the case of such a fitting, it is ensured initially in the factory that the correct screws are inserted into the correct perforations. The end customer no longer has to look for the correct screws. Instead, he or she can screw on the fitting directly, there being no complicated placing of screws on the fitting and furthermore precise positioning and prefixing are ensured by the protruding screw tips in corresponding bores in the component.

It is important to retain the screw in the perforation for the fitting according to the invention. In order to ensure that it is retained, it is provided that a perforation has a circular basic shape from which protrude segments or fingers which face radially inward and retain the tapping thread of a screw.

In addition to the screw being retained securely, it is also centered inside the perforation if three segments or fingers are provided with a 120° spacing.

In a further embodiment of the fitting according to the invention, it is provided that the diameter of a screw section between the head and the tapping thread corresponds to the diameter of the basic shape. This screw section can thus enter the perforation without any problems.

If it is furthermore provided that the axial length of the screw section corresponds to the material thickness of the fitting around the perforation, this screw section enters completely into the perforation and the section provided with the tapping thread protrudes completely from the fitting.

If the material thickness of the fitting is insufficient for this, it is furthermore provided that a ring, which forms a bearing surface for the underside of the screw head, protrudes from the fitting, around the perforation.

The fitting preferably takes the form of a drawer guide profile. In the case of such a fitting, a pair of perforations with premounted screws is provided at the end. It is furthermore provided that the perforations are disposed in a line in the longitudinal extent of the fitting. By virtue of these measures, such a fitting can be used in a versatile way with different items of furniture.

Such a fitting, which takes the form of a drawer guide profile, is further explained with the aid of the drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the figures of the drawings in detail and first, particularly, toFIG.1thereof, there is seen a drawer guide profile which is reproduced by way of example for a fitting1according to the invention. A side wall2of the fitting1is to be fixed to a component (not illustrated) of an item of furniture. It is fixed with screws3,4which pass through perforations5,6and enter into corresponding bores of the component of the item of furniture.

In the exemplary embodiment of the fitting1, a pair of perforations5,7;6,8is provided at each end along a line in the longitudinal extent of the fitting1. A wide range of fastening options for the fitting1is thus possible.

FIG.2shows the fitting1with the screws3,4inserted into the perforations5,6. The self-tapping screws3,4are premounted and inserted and retained in the perforations5,6so far that screw tips9protrude from the longitudinal wall2of the fitting1(compare the enlarged illustration inFIG.3).

FIG.4shows an enlarged plan view of the perforations5,7in the longitudinal wall2of the fitting1. It can readily be seen that these perforations5,7have a non-round form. Although the perforation7has a circular basic shape10, indicated in dashed lines, three segments11to13protrude radially inward from this basic shape10. The diameter of the basic shape10corresponds to the diameter of a screw section14between a head15and a tapping thread16of a screw17reproduced inFIG.5. The axial length x of this screw section14corresponds to the material thickness x in the region of a perforation18.

This is ensured in the case of low material thicknesses, such as in the case of the side wall2, by rings19,20and21shown inFIG.5, which protrude from the side wall2and form a bearing surface for the underside of the head15of the screw17.
