fastening elements, a procedure for the manufacture of a fastening elements and the use of a movable casing arranged at the fu00e4stelementet or procedure

摘要

The present invention concerns a mounting element ( 2, 10, 50, 1000 ) comprising a means of fastening ( 4, 12, 53, 102 ) such as a nut or bolt and an upper washer ( 14 ) and a lower washer ( 16 ) constituting a pari of washers, where each washer has one side with cams ( 18, 20 ) and one principally flat side ( 22, 24 ), the washer sides with cams being arranged facing each other. Moreover, the means of fastening includes a principally flat side ( 26 ) arranged against a principally flat upper side ( 22 ) of the upper washer ( 14 ). The said mounting element furthermore includes at least one means of containment ( 28 ) arranged to keep together the means of fastening and the pair of washers, whereby the means of containment is allowed a certain axial movement and rotation in relation to the means of fastening or the movement of the pair of washers. The present invention concerns also a means of manufacturing a mouting element and a usage.
