Definitions

  • the invention has for its object a device for removing dents in view of their easy handling to improve.
  • the invention proposes a device with the features of claim 1. Training the invention are the subject of the dependent claims, the Wording as well as the wording of the summary Reference is made to the content of the description.
  • the tension elements arranged side by side are with their Hooks hooked into the eyelets of the corrugated wire. Because the tension elements slidably supported in its own longitudinal direction , it is possible to mount them even if the Bump has a shape that is not the line of the hook of the Tension elements corresponds. Since the tension elements can only be moved are held, they can not move sideways.
  • the tension elements are rod-shaped. she can be held against rotation in further training, so that they cannot twist about their own longitudinal axis. This means that the hooks are always correctly positioned are and do not move away from this position can.
  • the tension elements have a starting position, in which they normally, i. H. before starting use, are arranged.
  • each tension element is adjustable. This can be achieved that the starting position of the Tension elements is brought into a shape that the desired End position of the bulged sheet corresponds.
  • the starting position can be defined by the Tension elements, when they are in the starting position, abut a counterstop with their stop.
  • the tension elements in their Starting position are spring loaded. This can be done, for example serve a compression spring that the rod-shaped Surrounds the tension element and thereby also against evasion is secured.
  • the Starting position of the tension elements by adjusting the stops and / or the stop counter element is changeable.
  • This can be provided that the individual tension elements in a Cross strut of the bow handle are stored.
  • Figure 1 shows a side view of one of the invention proposed device with which a concave dent a sheet metal part can be pulled out.
  • the device contains a bow handle 1 with a handle part 2 and two lateral parallel struts 3.
  • the handle is approximately U-shaped on.
  • Between the ends of the parallel struts 3 is a Cross bar 4 attached, for example with the struts 3rd is screwed.
  • the crossbar contains a large number of parallel ones Holes, in each of which a pulling element 5 can be moved is stored.
  • the tension elements shown in the Embodiment are all identical, included in the Area of their one end pointing away from the bow handle 1 a hook 6, see also Figure 3.
  • the tension elements 5 are through a sleeve 8 and one on the cross bar 4 facing away Inserted side of the sleeve across the tension element 5 Splint 9 secured against being pulled off.
  • the sleeve 8 is attached to the shaft of each tension element.
  • the sleeve 8 forms a together with the long side of the crossbar 4 Stop for the tension elements 5.
  • the hooks have a shoulder 10 facing the crossbar on. Between this shoulder 10 the hook 6 and the opposite one Longitudinal side 11 of the crossbar 4 are helical compression springs 12 used, the respective tension element 5th surrounded and the tensile elements acted so that the Sleeves 8 on the crosspiece 4 and the split pins 9 on the sleeves 8 issue. This way it becomes a home or zero position of the tension elements defined.
  • Hook 6 aligned linearly in its starting position.
  • FIG 2 is a cross section along an enlarged scale Line II-II shown.
  • the tension elements 5 and the holes have a cross-section deviating from a circle.
  • the cross section is shaped so that two are opposite each other Sides of a circle flattened parallel to each other are. In this way it is achieved that the tension elements 5 can be moved in their own longitudinal direction, but cannot twist. This causes the Keep hook 6 aligned.
  • the device shown in Figure 1 becomes as follows used.
  • a corrugated wire is welded in such a way that the waves of the corrugated wire protruding from the surface of the sheet form individual eyelets.
  • the distance between these eyelets is up the distance between the hooks 6 of the tension elements 5 matched.
  • the Device is gripped on handle 2 and the sheet or welded-on corrugated wire so that the hooks 6 in a line approximately parallel to the longitudinal direction of the corrugated wire run. As soon as the two outer hooks 6 the sheet reach, they can be hung in the corrugated wire.
  • FIG. 3 shows a section through an arrangement, for example along line III-III in Figure 1 in a slightly modified Embodiment.
  • the tension elements 5 in this embodiment have in their end area facing away from the hook 6 External thread 13 on.
  • the sleeves 8 are on the ends Screwed on nuts 14, which act as a stop here interacts with the long side 15 of the crossbar 4.
  • Snap ring 16 or a similar device is provided, to prevent the nuts 14 from being completely unscrewed.
  • the starting position of the Tension elements and thus the hook can be changed. Under In this embodiment, the starting position is the position to understand, in which the hooks are urged by the springs 12 become.
  • the embodiment of Figure 3 is used as follows.
  • the device is placed next to a location on the sheet the bump on, so in a place where the correct Curvature of the sheet metal part without the bulge is present. It can another vehicle of the same, for example Type or act as an apprenticeship.
  • the grip is against pressed the sheet metal part until all hooks 6 on the surface lie on. Usually this surface is not flat, or in other words, the tension elements are on the opposite inward side of the crossbar 4 different distances.
  • the nuts 14 of the tension elements that survive, as far as on the Screwed thread until the nuts 14 on the Fit along side 15. If the handle is then removed, so the starting position of the hook 6 is set as this corresponds to the final state of the bulged sheet.
  • the device is used in the same way as described above. This embodiment is then advantageous if the sheet is convex in its bulged state Has curvature.
