Description

[0010] The invention will now be described in more detail with reference to the accompanying drawings in which

[0011] FIG. 1 shows an oblique side view of an embodiment of a straightening apparatus according to the invention installed on the side of a vehicle, and

[0012] FIG. 2 shows an oblique side view of another embodiment of a straightening apparatus according to the invention installed at the front of a vehicle.

[0013] The straightening apparatus according to FIG. 1 includes a support beam 1 which contains a vertical beam 8 and an extension beam 9 fastened to it telescopically and movably in its longitudinal direction. At the top part of the vertical beam 8, there is a locking element 14 for locking the extension beam 9 to the vertical beam 8. In this embodiment, the locking element 14 is a locking screw. At the bottom part of the vertical beam on its one side is fastened a shaft to which are fastened wheels 10. To the bottom part of the vertical beam is fastened a straightening support 15 extending in the opposite direction in relation to the wheels, which support includes a hollow frame fastened perpendicularly to the bottom part of the vertical beam and a support beam movable and lockable in relation to it.

[0014] The straightening apparatus also includes a lower support section 5 fastened to the vertical beam and operating as a support element. This support section is movable/transferrable in relation to the vertical beam and lockable at a desired point in the vertical direction of the vehicle 3 in place by means of a locking element 16, such as a locking screw. At the end of the extension beam 9 is fastened a second, upper support section 6 operating as a support element. This support section is movable by means of the vertical beam and the extension beam at a desired height in relation to the vehicle. The support sections include two supports 17 provided with ball joints which supports are settable against the panels of the vehicle. The lower support section includes two support arms at the ends of which the fastening sections of the supports are fastened releasably and rotatably into different positions. The fastening sections of the supports can be rotated such that the supports can be set against the vehicle from the side, from above or from below. The upper support section includes an arm at the end of which there is a crosswise beam to which are fastened two supports.

[0015] Furthermore, the straightening apparatus includes a straightening fastener 2 movably fastened to the vertical beam and lockable to it at a desired point by a locking element and gripping elements 18 at its end for fastening onto the body panels of the vehicle. The straightening apparatus includes a transfer device 4 for transferring the gripping elements, which transfer device in this embodiment is an adjustable straightening screw. The gripping elements can be e.g. a hook, a catch, a suction pad or a pulling fork.

[0016] When using the straightening apparatus according to FIG. 1, the support beam 1 is first transferred in the horizontal direction at the point of the vehicle and its damage being repaired at a point suitable for straightening work and the support sections 5 and 6 are set at the points of beams being on the side of the vehicle and the straightening fastener 2 is transferred in the vertical direction at the point of the damage. In FIG. 1, the lower support section 5 is set at the point of the lower beam of the vehicle and the upper support section 6 is set at the point of the longitudinal upper beam of the vehicle. Then, the gripping elements 18 of the straightening fastener 2 are fastened on the body panel of the vehicle at a point suitable from the viewpoint of straightening work. FIG. 1 shows a straightening fastener fastened on a body panel being in the bottom part of the vehicle and dotted lines show its fastening to other heights. The straightening support 15 in the bottom part of the vertical beam has been pulled at a suitable length extending towards the vehicle. The straightening support supports itself on the chassis and keeps the straightening apparatus upright. The straightening work is started by tightening the straightening screw, whereby it pulls the body panel towards the vertical beam. The vertical beam stays in place because the support sections are against the body panel of the vehicle and support it.

[0017] In the embodiment according to FIG. 2, there is shown the vertical beam 1 according to FIG. 1 to which are fastened wheels and a straightening support. Furthermore, to the vertical beam are fastened movably in relation to it a support section 5 and a straightening fastener 2 which correspond the parts shown in FIG. 1. Additionally, the straightening apparatus includes ramps 11, fastening beams 12 adjustably fastenable to them in the longitudinal direction and a cross beam 13 fastened crosswise to the fastening beams in the vicinity of their ends. In the bottom part of the vertical beam, there are fastening elements for fastening the support beam 1 to the cross beam at a desired point.

[0018] The straightening apparatus according to FIG. 2 is intended to be used when straightening the body panels in the vehicle front or rear. As the straightening starts, the vehicle is transferred such that its front or rear wheels are on top of the ramps. In FIG. 2, the front wheels of the vehicle are on top of the ramps. After that, the fastening beams are transferred in relation to the ramps to set the cross beam at a desired point. Then, the vertical beam is fastened to the cross beam at a desired point in relation to the vehicle. Next, the support section is set at the point of the vehicle support beam or equivalent reinforced section and the straightening element is installed at a desired point. When the straightening apparatus is set in place, the straightening element is tightened by means of the screw and the body panel of the vehicle is pulled at a desired strength to straighten it. The vertical beam supports itself both on the ramps and the support section. The weight of the vehicle is applied on the ramps and they stay fastly in place and the fastening beams and the cross beam stay in place and also keep the vertical beam in place.

[0019] In the ramps according to FIG. 2, there also are on the sides fastening supports/sections 19 for fastening beams or equivalents on their sides. Thus if desired, the ramps can be used as a support for straightening work occurring on the sides of the vehicle if the straightening apparatus is supported in an equivalent way as in FIG. 2 to the ramps by means of the fastening beams and the cross beam.

[0020] The invention is not limited to the described advantageous embodiments, but it can vary within the scope of the inventive idea presented in the claims.
