Definitions

  • the present invention relates to a tool for manually straightening possible dents located in the sheet body of motorised vehicles.
  • the present invention relates to a tool of the above-mentioned type comprising a rigid body having at least one end adapted to be pressed against the dent so as to straighten it.
  • dents it is intended to mean any deformations in the sheet body of motorised vehicles usually caused by atmospheric factors such as hail, by mistakes in the vehicle production line, or by slight accidents during the use of the vehicle.
  • straighten With the term: “straighten”, “straightening”, it is intended to mean the operation of removing the dent by exerting a predetermined pressure on it so as to bring the sheet to its original status, in any case to have a perfectly flat (smooth) sheet without any hump or dip.
  • EP-A-0 681 876 shows some tools comprising a rigid metal body with a first end adapted to be pressed against the dent so as to straighten it; a second end opposed to the first one supplied with handgrip to allow the manual use of the tool, and a central part being a connection stem between the two ends.
  • the problem underlying the present invention is to provide a tool for manually straightening possible dents located in the sheet body of motorised vehicles.
  • the tool must be easy to use and effective, and it must allow a rapid and accurate straightening of the sheet without causing any damage to the external paint layer so as to prevent any depreciation of the vehicle or the need of costly repainting of the sheet body.
  • the above-mentioned problem is solved with the tool described above, which is characterised in that at least one end of the rigid body is coated with a synthetic material, preferably plastic.
  • a tool for manually straightening possible dents located in the sheet body of motorised vehicles comprising a rigid body having at least one end adapted to be pressed against the dent so as to straighten it, the end being made of a synthetic material, preferably plastic.
  • the present invention it is advantageously possible to straighten possible dents located in the sheet body of motorised vehicles quickly, easily and efficiently without any danger of breaking or damaging the external paint layer.
  • the part of the tool in contact with the dent is advantageously coated with or made of a synthetic material.
  • the end or ends of the tool to be pressed against the dent are slightly capable of being deformed so that, when said ends are pressed with force against the dent, they flatten enough to increase the supporting surface.
  • the tool according to the present invention is particularly easy to be manufactured and it does not require the use of expensive materials.
  • figure 1 shows as a whole a tool for manually straightening possible dents located in the sheet body of motorised vehicles.
  • Said tools can be of several shapes and sizes as they range from the hammer to the pin or strut as shown in figure 3, to the levers shown in figure 1.
  • Document EP-A-0 681 876 describes an example of how the dents located in the sheet body of motorised vehicles are usually straightened.
  • Tool 1 essentially comprises a rigid body 2 with at least one end 3 adapted to be pressed against the dent (not shown in the figure) to be straightened.
  • FIG 1 shows an S-shaped tool having a rigid body 2 which, besides the end 3, comprises also another end 4 on the opposite side provided with handle 5 to allow the manual use of the tool, and a central part 6 being a connection stem between ends 3 and 4.
  • Length and diameter of the central stem-part 6, as well as the shape of the pointed end 3 of the tool may vary freely according to the type of use required and the dent to straighten.
  • the angle of handle 5 with respect to the central stem-part 6 can vary at will according to the operator's requirements.
  • the handle may be placed on the same axis as the central part 6, or it may be rotated by 180° with respect to the example in figure 1 so as to have a U-shaped tool.
  • the type of tool shown in figure 1 is essentially used as lever by hooking the central part 6 to a removable rest fastened to an internal cavity in the sheet body of a motorised vehicle, and operating on handle 5 to press the end 3 with gauged strength against the dent so as to straighten the sheet properly.
  • the end 3 is advantageously made of a synthetic material, preferably plastic.
  • the sheet body does not require repainting anymore, and there is no risk that, while straightening the sheet, the motorised vehicle is depreciated due to breakage in the external paint layer. Furthermore, the presence of a tip (end 3) made of synthetic material surprisingly simplifies straightening operations too, since the operator's accuracy in pressing the dent is less critical.
  • Figure 3 shows a part of a tool for manually straightening possible dents located in the sheet body of motorised vehicles obtained according to another embodiment of the present invention.
  • the rigid body 2 is provided with at least one end 3 adapted to be pressed against the dent to be straightened, which is advantageously coated with a synthetic material, preferably plastic.
  • the coating of synthetic material is shown in figure 3 with the reference numeral 7.
  • the end 3 of the tool is of the prior-art type, that is, it is made of a rigid material, for example steel, integral with body 2.
  • the end 3 is an integral part of rigid body 2.
  • the end 3 adapted to be pressed against the sheet to be straightened is advantageously coated with a synthetic material (coating 7) so as to have all the aforesaid advantages with reference to the type of embodiment in figures 1-2, in particular greater ease and rapidity of use of the tool and protection of the paint layer coating the sheet body.
  • the latter is preferably provided with holes, notches or rough surfaces of various types that allow firm and strong fixing of the synthetic material.
  • numeral 8 in figure 3 shows a hole made in the end 3 filled with the synthetic material of coating 7, which keeps the latter in adherence with the end 3.
  • the tool shown in the example in figure 3 is used as pin or strut, that is, for direct transmission of the pressure exerted by the operator from a handle (not shown in the figure) to the end 3, and from this end to the sheet to be straightened.
  • the embodiment of the invention in figure 3 is particularly suited both for making new tools and, advantageously, for modifying already existing tools of the prior art. This way, they would be considerably improved by applying a coating 7 of synthetic material in correspondence with their working ends according to the present invention.
  • the preferred synthetic material is a relatively hard plastic material, such as NylonTM or TeflonTM.
  • said material has proved to have suitable features both with regard to its capability of being deformed when compressed, so as to guarantee an optimum distribution of stresses on the sheet to be straightened avoiding possible damage to the external paint layer, and with regard to wear resistance.
  • a coating 7 of synthetic material having a thickness ranging between 0,5-10 mm, preferably between 1-7 mm.
  • Said thickness is to be preferred since it allows exploiting at best the capability of being deformed features of the synthetic material and at the same time it is thin enough to effectively transmit the pressure exerted by the operator to the sheet.
  • a too thick or thin thickness may on the one hand not be effective anymore to prevent damage to the external paint layer. On the other hand, it may weaken the end 3 making it subject to break during use.
  • the tools object of the present invention can be used advantageously also in industrial fields (such as in the field of refrigerators) where, in order to prevent down-grading and depreciation of the finished product, the straightening of possible dents of painted sheet parts caused during the assembly and stocking of the product is required.
