Definitions

  • the present invention relates to a fastener being pressable into a metal sheet in a way safe against rotation and pressing out, having a head or ring the side of which after insertion facing the metal sheet is having radially positioned ridges, which, when setting the fastener, are pressed into the metal sheet, wherein a cylindrical thread-carrier is positioned in the centre of said ridges projecting through the metal sheet beyond the other side of the metal sheet and which in the vicinity of the side of the head or ring facing the metal sheet in the set state is having an annular recess into which the material of the metal sheet displaced during the setting can be pressed.
  • Such fasteners can be performed as bolts (having a shaft with an exterior thread) as well as nuts (having a through bore with an interior thread).
  • a corresponding fastener for example is known from WO 94/01688.
  • the present invention starts out from the fact that for achieving an optimal safety against rotation and pressing out with thinner metal sheets not too much space for the displaced material of the metal sheet should be provided but only the volume, which by a deliberate deformation (flowing) of the metal sheet can be filled in an optimal way.
  • This shaping into the annular recess is achieved by a flow shaping of the metal sheet material caused by the special shape of the ridges.
  • the above task is solved by the features that the ridges over a majority of their radial extension are having a constant height and width and are in the vicinity of the thread-carrier smoothly merging with the same with an increasing width.
  • the ridges are having a basically rectangular cross-section and their side walls are perpendicular to the side of the head facing the metal sheet. By this, the grip of the ridges in the metal sheet material is further improved.
  • FIG. 1 a side view of a fastener as a bolt according to the invention
  • FIG. 2 the fastener according to FIG. 1 in a bottom view, wherein the shaft is cut-off in the plane of the annular recess;
  • FIG. 3 a detailed view of the annular recess and the ridges of the fastener according to FIG. 1;
  • FIG. 4 a cross-sectional view of one ridge of the fastener according to FIG. 1, wherein the cross-section is across the longitudinal extension of the ridge;
  • FIG. 5 the fastener according to FIG. 1 shortly before being set in the metal sheet
  • FIG. 6 the fastener according to FIG. 1 after setting in the metal sheet
  • FIG. 7 a further embodiment according to the invention being performed as a nut, i.e. having an interior thread
  • FIG. 8 the fastener according to FIG. 7 in a bottom view (i.e. seen from the side of the metal sheet), and
  • FIG. 9 the fastener according to FIG. 7 partly in section in the state set in a metal sheet.
  • FIG. 1 is showing the fastener according to the invention in the form of a bolt, i.e. having a shaft with an exterior thread.
  • the fastener 10 according to the invention is having a head 12 and a shaft 14 carrying an exterior thread. Between the thread and the head 12 in the following order there are provided a calibration collar 16 , an annular projection 18 and an annular groove 20 having a generally semi-circular cross-section.
  • On the bottom side of the head 12 which is facing the metal sheet during the setting of the fastener, there are provided radially extending ridges 22 , which in their radial extension generally having a constant height and which are tapering off in a flat manner merely in their radial exterior area 21 .
  • the head 12 is shown partly in cross-section, wherein, on the right aide, the corresponding ridge 22 , too, is shown in cross-section while the corresponding ridge 22 on the left aide is shown in front view.
  • FIG. 2 is showing the head 12 of the fastener of FIG. 1 in a bottom view, wherein the shaft is cut-off in the plane of the annular groove 20 .
  • the shape of the ridges 22 is especially well shown.
  • the ridges 22 extend in a radial direction with a generally constant width and merely in the radial exterior area 21 near the exterior edge of the screw head 12 are tapering off in their height in a flat manner and are rounded in their width. In the direction of the shaft 14 , the ridges 22 in a rounded manner are merging with the annular groove 20 .
  • FIG. 3 is showing a detailed representation of the merger area between the head 12 and the thread-carrier 14 .
  • the tapering off of the ridge 22 in the exterior area 21 is especially detailedly shown.
  • FIG. 4 is showing a detail, namely, the cross-section of a ridge 22 , the section being across the radial direction of the head 12 .
  • the ridges 22 generally are having a flat rectangular cross-section and are limited by sidewalls 24 generally perpendicular to the level of the head 12 . Apart from that the surface of the ridges 22 facing the metal sheet during the setting generally are even and parallel to the plane of the head 12 .
  • FIG. 5 is showing the fastener according to FIG. 1 shortly before the insertion into a metal sheet 100 having a corresponding opening 102 .
  • the diameter of the opening 102 is chosen such that the fastener can be inserted with the annular projection 18 just without contact.
  • FIG. 6 clearly the indentations 30 are shown caused by the counter tool during the setting.
  • the annular groove 20 in the area of a ridge 22 has been filled completely with the displaced material of the metal sheet (right side in FIG. 6) while on the left side in FIG. 6 it is shown that in the area where there is no ridge 22 the annular recess 20 almost completely has been filled with the displaced material of the metal sheet.
  • FIG. 7 is showing a further emobdiment of the invention, wherein in this case the invention has been performed with a fastener serving as a nut, i.e. a fastener having an interior thread.
  • This further fastener 110 is serving as a pressable nut and basically is having a cylindrical shape. In the centre, the fastener is having a broad surrounding ring 112 . In a centre of the cylindrical fastener 110 there is a through-bore which at least over a part of the height of the fastener 110 is forming a thread-carrier 114 with an interior thread. Below the surrounding ring 112 , the central bore is increased in diameter, which means that in this area only a relatively thin annular surrounding ridge 118 is present.
  • the fastener 110 is meant to be inserted with the ridge 118 first into a hole in a metal sheet 110 .
  • the shape and the position of the ridges 122 can be more clearly described with reference to FIG. 8. This is showing the fastener of FIG. 7 from below.
  • the radially extending ridges 122 in their radial direction are having a basically constant width.
  • the radially exterior area 122 they are rounded in their width and are tapering off in their height.
  • They therefore are having a basically flat surface directed downwardly and being parallel to the level of the ring 112 and sidewalls basically perpendicular thereto.
  • the direction of the ring 118 i.e. to the interior the ridges 122 in a rounded manner are merging with said ring, which means that they are having a rounded increase of their width in the radially interior area.
  • the bottom side of the ring 112 in the direction to the interior can be slightly recessed such that in this area the bottom side of the ring 112 not is horizontal but slightly concave.
  • FIG. 9 is showing the fastener of FIG. 7 in the set state.
  • the fastener 110 is pressed into a hole in the metal sheet 100 having a corresponding diameter.
  • the hole in the metal sheet 100 should have a diameter, which makes it possible to insert the fastener 110 with the surrounding ridge 118 just without contact in the hole 102 .
  • the surrounding ridge 118 by a suitable counter tool is pressed to the exterior whereby the metal sheet is displaced into the edge between the surrounding ridge 118 and the ring 112 and between the corresponding ridges 122 .
  • the shape of the ridges 122 is of fundamental importance to achieve a complete filling of the space between the surrounding ridge 118 and the ring 112 even when setting the fastener according to the invention in a very thin metal sheet 100 .
