The present invention relates to installations for the repair and the checking of vehicle bodies, which, for example, have been damaged in an accident, and more particularly, to such installations of the type including a free-standing bench and a pulling tower assembly.
In order to execute a repair, especially by straightening of the pieces of sheet metal of a vehicle, an apparatus including a pulling tower assembly is generally used in conjunction with a bench to which the vehicle is secured by way of suitable clamps or jigs. The pulling tower assembly comprises a base constituted by an elongated member, such as a tubular beam capable of being slid beneath the bench and being equipt with means for clamping onto the frame of the bench. The bench is constituted by a rectangular frame made of two U-shaped and I-shaped metallic side members assembled together by two cross-pieces between the two longitudinal side members. The bench includes clamps for anchoring the body of the vehicle to be repaired, and cross-members which mount assemblies for repairing the vehicle and measuring apparatus.
At one end of the base-forming beam of the pulling tower, there is mounted an arm which is articulated around a horizontal shaft which extends transverse relative to the beam. A chain has one end hooked onto the vehicle body and its other end attached to the arm, which is adapted to be moved around its shaft and exert a traction on the chain, under the action of a hydraulic jack.
FIG. 1 is a perspective view of the bench and pulling tower assembly of the present invention;
FIG. 2 is a longitudinal section view through a vertical plane along line 2--2 in FIG. 3, of the pulling tower assembly and of the end of the bench to which it is affixed;
FIG. 3 is a top plan view of the bench and pulling apparatus of the invention;
According to the invention, bench 2 comprises a frame 4 made from four tubular elements 4a-4d, between the two longer sides 4b and 4d of which are mounted two transverse crosspieces 5.
In a manner known in the art, the bench is equipt with wheels 6 which permit its displacement on the ground, with clamps 7 for securing the chasis of the vehicle to be repaired to the bench, and with a frame-like device indicated generally by reference 8, which permits the assembing of various control accessories onto the bench.
As it can be seen in FIG. 2 of the drawing, element 4a of the rectangular frame 4 is equipt, on its inner surface and near the lower edge thereof, with a flange 9 in the form of a metallic element square cross-section. The flange 9 serves the double function of reinforcing the rigidity of the tubular frame 4 and making possible securing of the pulling tower assembly to the frame 4.
