In a development of the invention it can be provided that the Display has a scale and a pointer. It does it possible for the user to see how far from the Target position is removed.

To make the device safe even on curved surfaces To be able to use, the invention proposes that the Bracket has at least three feet, possibly one have a somewhat softer surface. In particular, can be provided that the mounting feet on a ring element are arranged, which is adjusted relative to the rest of the holder can thereby be the zero position or the To be able to set target position.

The actuator with which the fitter pulls can perform, for example, a mother on one Screw spindle. However, it is particularly favorable if the actuating element is a lever articulated on the holder which engages an element of the tension element.

The invention also proposes the use of a device as described for performing a bulge or to determine the correct bulge in front.

The device can be used so that the for a certain bump selected adhesive adapters in the device hung and the device on one of the bump similar Place is put on. It can be a part act of a motor vehicle, or also an apprenticeship. The correct position of the tension element at the point where none Bump is then marked. Then the adhesive adapter glued into the bump and the device with the Adhesive adapter connected. Then the bump is pulled out so far until the previously set mark is reached.

Further features, details and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Here show:

Fig. 2
the device in its starting position before pulling out a bump;
Fig. 3
the side view of a further embodiment;
Fig. 4
a longitudinal section through the embodiment of Figure 3;
Fig. 5
a cross section through the embodiment of Figures 3 and 4.

The device shown in Figure 1 contains a housing 1, which is provided with a handle 2 in the area of its upper side is. The handle 2 goes in at its other end a handle leg 3 over, possibly with a plastic coating 4 to form an ergonomically shaped handle can be provided. The housing has a bottom 5 which with a cylindrical extension 6 in the middle on its underside has a cylindrical bore. In the cylindrical Bore of the neck 6, a rod 7 is slidably mounted, those in the area above the bottom 5 from the device protrudes. At its opposite lower end it has a receptacle 8 for an adhesive adapter 9.

On the underside of the bottom 5 there is an adjusting ring 10 rotatably supported, a thread on the inside having. A ring element 11 is screwed into the thread, that contains three spacer bolts 12. The spacer bolts 12 run parallel to one another and to the pull rod 7. The spacer bolts 12 are in the area of their free ends Attach feet 13 provided.

In the housing 1 there is a lever 14 above the bottom 5 articulated, which can be pivoted about the articulation axis 15. The lever 14 also has a coating 16 made of plastic. The lever 14 has a flange 17 which is approximately parallel runs to the articulation axis 15.

The pull rod 7 contains above the flange 17 of the lever 14 a transverse pin 18 on the top of the flange 17 rests.

On the upper side of the device there is a pointing element 19 which points with a pointer 20 to a scale 21 which is arranged at the end of the pull rod 7 protruding from the device.
Because of their weight, the pull rod 7 and the lever 14 are pivoted downward. When a fitter engages the lever 14 and approaches the handle 3, he simultaneously raises the pull rod 7 so that the pin 18 is acted upon by the flange 17. The movement of the pull rod can be read on the scale 21.

The device serves to remove a dent 22 from the sheet 23 pull out. The procedure is as follows. For the bulge 22 present in the sheet 23, see FIG. 2, becomes first the suitable or suitable adhesive adapter 9 is selected. This must be adapted to the shape and size of the bulge 22 his. The adhesive adapter is then in the receptacle 8 Pull rod 7 inserted, and the device is then on set a location of the sheet 23 that does not contain a dent. In the example shown, it is a flat piece Sheet metal, so that the device to any other Can be placed on a flat sheet. If it a bump in a curved sheet metal part acts, the device must be placed on one place that have the same curvature. For example one fender could be the one on the opposite Side of the vehicle's existing fender act.

Then, by turning the adjusting ring 10, the device set so that the pointer 20 is at the zero of the Scale 21 stands. You could also do it yourself notices at which point on the scale the pointer 20 without Adjustment of the adjustment ring stands. The procedure for which the pointer 20 is set to zero, but is the preferred.

The adhesive adapter 9 is then removed from the receptacle 8 removed and glued into the bulge 22. Then he will hooked back into the receptacle 8 of the pull rod 7. The The fitter now grips the two handle legs with one hand 3 and 14 and pull the pull rod up until the Pointer 20 is again on the zero of the scale 21. He knows now that he pulled the bump out correctly.

The embodiment shown in Figures 3 to 5 also includes a housing 31, for example Sheet is made. The housing contains 2 parallel side surfaces 32, 33 that end in legs 34. The slightly spread Legs 34 are connected to a ring element 35, for example welded.

The two parallel side surfaces 32, 33 are on their Ring element 35 opposite side connected by a web 36, which laterally forms an approximately U-shaped lever 37.

Between the two side walls 32, 33 there is a shaft 38 pivotably mounted a second lever 39, which is in cross section is also U-shaped.

On the top 40 of the web of the second lever 39 is a Slide shoe 41, with a pin 42 through an elongated hole 43 engages in the front wall 32 and the rear wall 33. On the front, see Figure 3, the pin 42 has one widened head 44 with a mark in the form of a Notch 45 on.

The pulling element 46 provided with the adapter is inside the Housing held non-rotatably, being from top to bottom can be moved. From its ring element 35 facing away from an axial extends Threaded bore 47 into the tension element 46.
