US 5,509,289 A · Portable vehicle frame straightening apparatus

Abstract

A portable frame straightening apparatus for straightening and repairing vehicles which is comprised of a frame structure (1) to which the damaged vehicle (124) is attached. The structure (1) is bolted to a plate (21) which is anchored to the floor. The frame structure (1) and the attached damaged vehicle (124) can be rotated to achieve the desired angle of pull needed to repair the damage. The structure (1) is then secured to the floor with a chain (214) on either side which are fastened to anchors (216) in the floor so as to prevent rotation of the structure (1) while pulling. An independently standing pulling tower (213) which is also rotatable in a similar fashion to the plate (21) can accommodate various vertical adjustments for height variation as needed in pulling on the damaged vehicle. By removing the center bolt (107) which holds the frame structure (1) to the plate (21) that is anchored in the floor, the assembly (1) can easily be loaded on a cart (270) and moved to clear the floor space for other types of work.

Dependent claims

A portable vehicle frame straightening device, comprising:

(a) a rotatable carriage, the rotatable carriage being pivotably affixed to a single anchor by a centrally located spindle, the vehicle being affixed to the carriage;
(b) a first chain, the first chain having a first end and a second end, the first end being attachable to the vehicle;
(c) a tower, the second end of the first chain being affixed to the tower, the tower including a plurality of wheels, the wheels thereby permitting the tower to be rolled across a floor;
(d) a cart, the cart being adapted to receive components of the rotatable carriage, the cart including a plurality of wheels, the cart thereby permitting storage and relocation of the rotatable carriage;
(e) four chain retaining members, each of the four chain retaining members being affixed to the rotatable carriage;
and
(f) a second chain, the second chain having a first end a second end, the first end of the second chain being affixed to a single anchor site, the second end of the chain being affixed to one of the four chain retaining members, the second chain thereby preventing rotation of the rotatable carriage when a tensile force is applied to the first chain.
