BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a U-shaped slip-on slide nut having two parallel sliding legs with detent elements which can be clipped on an undercut bar, wherein one sliding leg has a bore and the other sliding leg has a threaded bore, aligned with the bore, for a clamping screw.
2. Description of the Prior Art
Slip-on slide nuts of this type are known from German Patent References DE 25 43 021 B2 and DE 35 24 400 C3 and are employed for diverse uses. The fastening screw can in this case be used for axially positioning the slip-on slide nut on the bar. Furthermore, as known from German Patent Reference DE 35 24 400 C3, it is possible to fix an additional component, for example a front panel, in place on a component provided with a bar, such as a connecting bar. The front panel has a fastening bore aligned with the bore and the threaded bores in the sliding legs. This dual function of the fastening screw makes assembly considerably more difficult, since it is necessary, in addition to positioning the slip-on slide nut on the bar, to align simultaneously the front panel with respect to the slip-on slide nut. However, this is practically impossible to perform by a single person without assistance.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a slip-on slide nut of the above-discussed type, wherein positioning on the bar and application of an additional component can be easily performed by a single person.
In accordance with this invention this object is attained with a bore that is embodied as a blind bore and the clamping screw as a flat head screw. At least one sliding leg has a screw receptacle for a fastening screw.
The slip-on slide nut can be clipped on the bar and can be positioned on the bar. Subsequently the additional component can be fastened to the slip-on slide nut with the additional fastening screw. The flat head screw does not hinder attachment of the additional component. In this case the screw receptacle can be formed in the sliding legs outside of the blind bore or the threaded bore for the clamping screw, but inside or outside of the area of the sliding leg receiving the bar.
In this case the screw receptacle is preferably embodied as a bore for a tapping fastening screw, or the screw receptacle is designed as a threaded bore for the fastening screw.
An improved fixing of the slip-on slide screw in place on the bar is attained with a further embodiment wherein the sliding leg not provided with the screw receptacle has a bore, which is aligned with the screw receptacle, for the fastening screw.
A slip-on slide nut which is easily and cost-effectively produced is distinguished in that the slip-on slide nut is formed from a stamped and bent element, wherein free ends of the sliding legs have end sections which are bent inward toward each other and are used as detent elements.
BRIEF DESCRIPTION OF THE DRAWINGS
This invention will be explained in detail by means of an exemplary embodiment represented in the drawings wherein:
FIG. 1 is an exploded perspective view of a slip-on slide nut;
FIG. 2 is a perspective sectional view taken through an additional screw receptacle for the fastening screw;
FIG. 3 is a perspective sectional view taken through the blind bore and the threaded bore for the clamping screw; and
FIG. 4 is an exploded perspective view of an attachment of a panel-shaped component to a profiled section having an undercut bar with a slip-on slide nut.
DESCRIPTION OF PREFERRED EMBODIMENTS
The slip-on slide nut shown in a perspective view in FIG. 1 is produced with a uniform wall thickness and therefore can be manufactured in a simple and cost-effective manner as a stamped and bent element 10. The U-shaped slip-on slide nut has two parallel and spaced-apart sliding legs 11 and 12 which, on their free ends, have end sections 17 and 18, which are bent toward each other. These end sections 17 and 18 and the distance between the sliding legs 11 and 12 are matched to the undercut bar 19 of a profiled sectio
