Definitions

  • the invention relates to fasteners for connecting a pivotable lever to an edge of a plate or frame or the like. with two connection angles protruding from the edge for pivot points of the lever and a fastening plate connected to these connection angles and angled in the direction of the plate or frame surface and having at least one fastening hole for a screw or rivet.
  • the fastening plate with at least one fastening hole which is angled in the direction of the plate or frame surface, sits on a longitudinal edge of this sheet metal strip resting against the edge.
  • fasteners are simple to manufacture, since only the connection angle and the fastening plate each have to be bent through 90 ° relative to the sheet metal strip, but the disadvantage is the inevitable high proportion of waste when cutting the fastener blanks from sheet metal.
  • the present invention has for its object to change the construction of such fasteners according to the preamble of claim 1 so that with the same security and strength of the connection between lever and plate or frame, the material cost of sheet metal is significantly reduced.
  • the new production methods a multiple bending of workpieces is less expensive than a high cost of materials. The latter is particularly disadvantageous in mass production.
  • the mounting plate and the connection bracket are components of a continuous sheet metal strip with inclined transition areas, each of which includes an angle of 90 ° both with respect to the mounting plate and with respect to the connection angles.
  • the more or less long sheet metal strip, which previously touched the edge is avoided.
  • the parts of the transition areas lying against the edge now require a significantly smaller amount of sheet metal or material than the sheet sheet strip which was previously continuous.
  • the fastening piece is designed according to claim 7.
  • fastening screws can be introduced into the edge, which ensures a secure fit of the fastening pieces.
  • the new structural design of the fastening jig also simplifies their cutting lines or cutting edges in such a way that the smallest possible amount of waste arises when the blanks are cut out of the coils.
  • connection angles are bent at right angles at the ends of a relatively long sheet metal strip. Holes can be seen in the connection angles, into which, for example, pivot pins of a movable lever can be introduced.
  • holding pieces are angled, in which fastening holes for fastening screws or rivets are arranged.
  • the relatively long sheet metal strip is in the assembled state of a fastening piece on the edge 37 of a plate or frame 38 (see FIG. 4).
  • Fig. 2 shows a first embodiment of the invention and Fig. 5 shows the associated sheet metal section.
  • the fastening piece 1 has a fastening plate 11 with a fastening hole 4.
  • the mounting plate 11 has an arcuate outer edge 18.
  • connecting bracket 5 are provided, which together with the fastening plate 11 are components of a sheet metal strip 14. Between the connection angles 5 and the mounting plate 11, the sheet metal strip 14 has transition regions 15 and 16. These transition areas have an arcuate inner edge 17.
  • Fig. 2 shows the fastening piece 1, which emerged from the fastening piece blank 1a, in a perspective view.
  • the fastening plate 11 is bent around the base points 19 and 20 relative to the transition regions 15 and 16 of the sheet metal strip 14 by 90 °.
  • the connection angles 5 are also bent by 90 ° around the same base points, so that a figuration according to FIG. 2 results.
  • pivot pin 9 or pivot holes 10 can be provided for connecting the movable lever, not shown.
  • the distance 7 between the connection angles 5 corresponds to the width of the fastening plate 11 between the base points 19 and 20th
  • Fig. 5 shows that the distance between the base points 19 and 20 is designated 6.
  • a fastening plate 12 has an arcuate outer edge 18 and is provided with a fastening hole 4.
  • the mounting plate 12 is delimited by an arcuate inner edge 17.
  • the transition regions 26 and 27 are designed as relatively long sheet metal strips. They end in foot points 23 and 24 with a distance that is designated by 21.
  • the parts 36 are bent at right angles, in which fastening holes 4 are provided and with which the fastening piece 2 can additionally be fastened to the edge 37 of a plate or a frame 38 (FIG. 4).
  • connection bracket 5 are bent at right angles, in which pivot pin 9 or pivot holes 10 can in turn be provided.
  • pivot pins 9 or pivot holes 10 define the pivot axis 8.
  • the distance 25 between the connection angles 5 is substantially larger than the distance 21 between the base points 23 and 24.
  • FIG. 4 shows a further exemplary embodiment of the invention, namely a fastening piece 3, for which the sheet metal cut or the fastening piece blank 3a is shown in FIG. 8.
  • the fastening piece 31 according to FIG. 7 is to be replaced by the fastening piece 3.
  • the disadvantageous fastening piece 31 had an extremely long sheet metal strip 34, from which the fastening tabs 32 protruded at right angles. This configuration resulted in extremely unfavorable sheet metal cuts with considerable waste 35.
  • the fastening piece 3 according to FIG. 4 has a fastening plate 13 designed as a sheet metal strip with two fastening holes 4 on.
  • the transition regions 26 and 27 between the mounting plate 13 and the connection brackets 5 are designed as sheet metal strips.
  • the mounting plate 13 is bent at right angles around the base points 23 and 24.
  • the connection angles 5 are in turn bent at right angles. The distance between them is labeled 25.
  • the mounting brackets 5 in turn have pivot pins 9 or pivot holes 10 on the pivot axis 8.
  • FIG. 4 shows how a fastening piece 3 rests on the edge 37 of a plate or frame 38.
  • the fastening plate 13 is fastened to the plate or to the frame 38 by means of two screws, not shown.
  • the fastener blank 3a is shown as a sheet metal section.
  • the transition regions 26 and 27 as well as the connection angles 5 which have not yet been bent over are clearly recognizable.
  • the waste 35 between the individual die cuts is very small.
  • the inner edge of the sheet metal strip 14a forming the fastening plate 13 is, like its outer edge, a straight line.
