Definitions

  • This invention relates to the field of repair of sheet metal components of auto bodies which have dents caused by collision or similar events.
  • the sheet metal to be straightened is frequently part of a box-type self-supporting structure formed by two layers of sheet metal, one on top of the other, and separated by gaps of varying shapes resulting from the way in which the different components are formed in order to obtain the desired resistance to static and dynamic stresses.
  • hammering of parts in the few cases in which this is possible, does not result in a finished job which meets the quality requirements of the trade, due also to the difficulty of conducting an effective examination of the finished work.
  • the irregularity in the sheet metal is considerably minimized but not flawlessly removed.
  • the dent be filled in with putty to easily create a flat surface which can subsequently be repainted.
  • the inventor with the intention of eliminating problems of the type described above, has developed a process which allows an indefinite number of damaged and dented areas to be pinpointed and repaired quickly and flawlessly without having to remove the paint, putty and repaint the parts.
  • the scope of the invention extends to a device suitable for carrying out this process.
  • the process begins with placement of one or more lamps (one in Figure 1) which extend(s) linearly over a support member 2 with respect to which the lamp can slide and rotate.
  • the lamps are then fixed at a height which will ensure that their image reflected by the sheet metal will be within the range of an observer's eye 3, or better, that of an operator in charge of making the repair, when they are in a location suitable for carrying out the operation.
  • Figure 2 shows the distorted image produced by a dent in the sheet metal, making it inwardly concave, as in the case of Fig. 1; in the case that the sheet metal is on the other hand dented so as to be convex, the image will also be distorted in some way, although the reflected lines will run in a different direction, that is, instead of diverging, they will converge, intersecting at the vertex of the part with the dented surface (this case is not shown in the figure).
  • lamps and levers used in the device can be modified and configured in such a way that the device conforms better to individual cases and different requirements, but the processes and devices included in the descriptions in the attached claims are in some way within the scope of the protection conferred by this patent application.
