  • the arm is additionally movable lengthwise relative to the turning member, and when the tool can moreover be tumed relative to the arm, the tool situating at the end ofthe arm can be attached in the exactly right place in the work object, e.g. in the vehicle frame.
  • the device is simple in construction, it can be produced with low costs and it is easy to use.
  • the locking in the different embodiments ofthe invention can be provided in an earlier known way e.g. with the help of screw, pin, toothing, friction or cone locking methods.
  • another lengthwise adjustable and lockable arm where the tool is attached, is mounted onto the first arm.
  • the other arm is advantageously a pole-formed member rotatably attached to a support provided at the end ofthe first arm.
  • the second arm can also be adjusted by rotating it about its axle, the arms can be tumed and adjusted exactly in the right place from the desired direction whereby the pull, push and supporting are performed precisely from the right direction.
  • the vehicle can e.g. be mounted in the straightening system or supported during the straightening work, and additionally, the straightening tool can be installed and focused from the right direction.
  • the positioning device incorporates locking members spaced at a distance for mounting the frame into the mounting member.
  • the locking members situating at a distance from each other, a spotwise, efficient locking can be provided.
  • the locking screws create a spotwise locking, which also is efficient when the amount ofthe locking screws is sufficient.
  • the device comprises a heightening arm which is attached onto the first arm and which extends upwards.
  • the heightening arm With the help ofthe heightening arm the tool attached onto it reaches farther from the beam and the said tool can therefore be extended e.g. in the vehicle upper structures.
  • the first arm inco ⁇ orates adjusting and locking members which adjust the length ofthe second arm and focus the tool in place.
  • adjusting and locking screws or hydraulic adjusting and operating apparatus can act as adjusting and locking instruments.
  • Figure 1 shows in a side view an embodiment of the positioning device according to the invention attached to the beam ofthe vehicle straightening system
  • Figure 2 shows in a side view the device illustrated in Fig. 1 attached to the beam ofthe straightening system
  • Figures 3 and 4 show a second and a third embodiment of the device according to the invention attached to the straightening system
  • Figure 5 shows the tuming member ofthe device partly in cross section
  • Figures 6 and 7 show a certain use of the device according to the invention when straightening the vehicle.
  • the positioning device comprises a mounting member 2 attachable to the beam 1 ofthe straightening system ofthe vehicle 12 and a frame 3 turnably attached to it.
  • the frame 3 inco ⁇ orates a turning member 5 tumably attachable to the mounting member and lenghtwise movable arm 6 attached to the turning member.
  • the turning member 5 is attached to the mounting member 2 with the help of the locking members 9.
  • the hole 20 is formed in the middle ofthe turning member and arm 6 is placed lenghtwise movably into this hole.
  • the hole is mainly rectangular and the cross section has also corresponding rectangular shape.
  • the device additionally comprises locking members 8 for attaching the arm to the tuming member.
  • the arm has lenghtwise grooves, on which the locking members locate.
  • the mounting member 2 is a movable member on the beam 1 attached to its locking member beneath the beam with locking pins 14 and is tightenable firmly against the beam with the help ofthe locking pins and the locking member.
  • the mounting member is round shaped and the turning member is lockable with the help of the locking members in desired position relative to the mounting member. This kind of mounting member is movable along the beam to the desired point with respect to the vehicle frame, which thus enables an easy positioning ofthe tool.
  • the device is attachable to the lenghtwise or crosswise beam ofthe straightening system.
  • the fastener 15, to which the tool 4 is attached turnably, is placed at the end ofthe arm 6.
  • the tool is lockable with the help of locking members located on the sides ofthe fastener in desired position.
  • the vehicle is attached to the straightening system with two devices according to the invention.
  • the constmction ofthe device corresponds to one shown in Fig. 1, but another arm 7 is attached to the fastener 15 located at the end ofthe arm 6, the said arm extending at right angles with respect to the arm 6, in other words it is in vertical direction with the respect to the straightening system and the beam.
  • the locking nuts function as locking members 12 ofthe arm.
  • the arm 7 is a bar and is tumable about its axle i.e. is rotatable round the fastener 15.
  • Another fastener 16 is attached to the end ofthe arm 7 and a third arm 13 is attached to this fastener.
  • the fastener 16 situates crosswise at the end ofthe arm 7 and thus the arm 13 is at right angles with respect to the other arm 7.
  • arm 13 is a bar and rotatable with respect to its fasteners.
  • the device comprises adjustment and mounting members to adjust and lock the arm member with respect to fastener 16.
  • a third fastener 17 is located in the end ofthe arm 13, to which an earlier-known clamping member 4 is attached, said clamping member being attachable to the frame ofthe vehicle 12.
  • the clamping member 4 is attached rotatably to the fastener 17.
  • the clamping member is attachable to extend to either downward or upward from the fastener, and thus the device is also adjustable in this way and the clamping member can be set to the desired place.
