Nut made of resilient sheet metal

The innovation relates to the improvement of a known nut made of resilient sheet metal, the single thread of which is formed in a circumference of almost 360 ° by the edges of the hole and a hump that is pressed out of the sheet metal. The design of such nuts is not limited to the shape of a simple plate with a bulging hump, but rather this plate can be provided in various ways with extensions that extend the basic shape of the nut in the form of bends and serve to fasten the same to one of the objects to be screwed together * By first fastening the nut to one of the parts to be joined, the assembly is mostly made much easier if the nuts are in inaccessible places after the 3 parts have been joined. The innovation that is described and illustrated in a special exemplary embodiment is limited thus not on an embodiment of the mother with regard to its own assembly serving approaches

Sole marriage of resilient sheet metal nuts with a thread of almost 360 ° compared to other training courses of the thread turn on nuts made of sheet metal a higher one

Take up the tightening torque and are de shall? "especially for connections subject to high loads · A disadvantageous property of these nuts is that the screw connection is relatively easy to unintentionally loosen when it is subjected to vibration is exposed · The aim of the ■ combustion is to create a vibration-proof nut made of resilient sheet metal the shape of the thread described above

This is achieved by two opposing arms on the longitudinal edges the nut reaches »which are bent into a J-shape, with the short legs of the J-shape merge into the bleed plane and the long leg of the J-IOrm, the threaded opening in the bleed plane bridge, thereby forming an obtuse angle and at their free ends a gap that is narrower than the thread— The diameter of the associated screw is · Both free ends have crescent-shaped, upturned necks in the middle are highest in the middle and there the greatest clear width each other, but less than the diameter of the Is very bare. The curvature of the shrouds is the thread ** outside diameter of the viewing hoods adapted

If a vision hood with a longer shaft is used after a ** screw in the thread turn of the sheet metal nut »see above first insert it into the opening through the necks is formed on the arms · Because of the smaller inside width of the opening compared to the screw-diameter knife the arms are pressed apart when the visual hood is turned further, so that the visual hood thread is pre-tensioned against the Necks of the arms. This means that the speed nut is with equipped with a safeguard against unintentional loosening »

In the drawing is an embodiment of the! Price increase a U-shaped push-on nut is shown »

Fig. 1 shows the sheet metal nut in section »

Fig »2 shows the cut nut in the installation position together with the screw and the connected parts, one plate-shaped and a profiled object.

Fig. 3 is the plan view related to Fig. 1, Fig. 4 shows the mother in "perspective.

In detail, Fig. 1 shows the perforated hump 2 with the radial slot 2a and the thread 3 on the rim of the plate-shaped nut 1, which is bent up at its free end. The nut 1 is through an arcuate web 1a the advanced * set 1b hole 1c _t whose Ausdrüekung 1d after the free end of the port set out runs "at the" Mother 1 Lang.skan.te extends beyond the thread 3, the arm 4 with its neck 4a »

Fig. 2 shows an installation example of the nut "The expression 1d on the edge of the hole of the extension 1b anchors the nut to the angular bracket part 5. The screw 6" protrudes through the hole in the port set 1b and holds a flat structural part 7, engages in the thread 3 of the hump 2 and is held on the rope protruding therefrom by the neck 4a of the arm 4:,;

In Fig »3 you can see the arms 4 overlapping the thread 3 with the Aushaisungen 4a and on the port set tb the Aus- pressing 1d of the screw hole,

Fig »4 shows the details mentioned and you can see that 3ioch Ic in port set 1b, furthermore the J-shaped arms 4 with Collars 4a which form the τ-oifl Iioehrand of the cusp 2 Reach over thread 3.
