Definitions

  • Collision repair racks also known as straightening benches, are widely used in the vehicle repair industry. Such racks are used to straighten vehicle (car, truck, etc.) bodies and frames that are damaged by a collision or the like.
  • Such racks include a platform having a deck for supporting a vehicle such as a car or a truck, one or more jack devices operable to selectively elevate and lower the platform and one or more pulling towers to apply straightening force to the vehicle chassis or body.
  • a pulling tower is a device mounted to the platform that is operable to apply a pulling force to a portion of the vehicle to which a pulling member is attached, to pull the body and or chassis back more to its original position and/or shape.
  • such a tower comprises a mounting arm, a tower and a power operated pulling device.
  • the pulling tower device is typically moveable relative to the platform to more accurately align the position and direction of pull applied to the vehicle. By being moveable, more precise and efficient straightening of the vehicle can be achieved.
  • Several modes of moving a pulling tower device to a position and fixing it in a desired position are known in the industry.
  • One form of pulling tower device is moveable on a track from one position to another position.
  • a second type of device has a pulling tower mounted on an arm that is pivotally mounted to the platform. The pulling tower is moved to its desired position and the arm is then fixed in the desired position with a lock device. While currently available racks are effective in use, the movement of a pulling tower device has been limited due to the use and position of additional pulling tower devices mounted to the platform and their interference with one another or the manner of pivotally mounting the pulling tower device to the platform.
  • Two types of pivoting mounts are known in the art. One is where the arm of each pulling tower device has its own separate pivot. The use of a separate pivot for each arm limits the ability of the arms of each pulling tower device to be moved relative to one another without interference.
  • Another type of rack uses a plurality of pulling tower devices each mounted to a common pivot with the arms being superposed.
  • the problem with the latter approach is the height required to accommodate the arms. It is desired, in many situations, to have a rack with a low profile to facilitate moving the vehicle to a low work height which height is limited by the superposed relationship of the arms of the pulling tower devices.
  • the present invention provides a rack that provides improved movement of pulling tower devices while providing a low profile.
  • the invention involves the provision of a vehicle repair rack.
  • the rack includes a vehicle support platform adapted to support a vehicle thereon for repair.
  • the platform has an outer periphery formed by front, rear and side portions.
  • the platform includes an upper deck adapted to receive and support a vehicle.
  • a plurality of pulling tower devices are provided and are mounted to the platform in a pivotal manner.
  • a pulling tower device includes a pulling tower and an arm. The arm is pivotally mounted to allow movement of the pulling tower to desired locations.
  • a lock mechanism is provided to secure the pulling tower in its selected position.
  • the pivotal mounting of the arms is such as to provide a low profile and the ability to pivotally move at least about 180° without interference between the arms.
  • the pivoting can be achieved by mounting the arms in a pivotal manner on a turntable which in turn is rotatably mounted to the platform.
  • the arms lie generally in a single plane and are positioned side by side and the arms can be pivotally mounted to another arm providing at least one arm with the ability to pivot about two pivots.

  • Removal of a lock pin 54 allows a respective member 49 to be pivoted downwardly and out of the way and providing the notch 51.
  • an arm 19 may pass or be positioned thereunder. Because the member 49 is hinged on the bottom and locked on the outer edge 11 or 12, the member 49 will help resist the bending moment when the pulling tower device 16 is applying force to a vehicle.
  • the deck 5, as best seen in Figs. 1, 10 includes a plurality of through openings 57.
  • the openings 57 are preferably elongate and can be in the form of rectangles extending lengthwise in the direction of the longitudinal axis of the platform 3.
  • the openings 57 are useable for securing anchors 58 (Figs. 2, 10) to the platform 3 which in turn are used to secure a vehicle (not shown) against movement while positioned on the platform.
  • the openings 57 can also be used as a portion of a lock mechanism 21 for securing the pulling tower devices 16 in a desired position as described in detail below.
  • a plurality of pulling tower devices 16 are provided. At least two pulling tower devices 16 and preferably three are provided at an end of the straightening bench 1.
