Description: FIELD OF THE INVENTION The present invention relates to an apparatus for securing vehicles to a frame straightening rack, bench or floor system and more particularly to an apparatus having a universal base assembly which is compatible with the various attachments which are required for each vehicle body design. BACKGROUND OF THE INVENTION The introduction of new automobile body styles and variations in manufacturing techniques has made it necessary to provide a specific set of attachment heads for each of the various body styles in order to properly secure a damaged vehicle to a frame straightening rack, bench or floor system. In order to repair a damaged vehicle, it is important for the vehicle to be securely mounted on a frame straightening rack so that the exact location of the data points on the vehicle can be measured and repaired. The conventional attachment system for securing a vehicle to the rack requires four double clamp type attachment devices each of which is attached to the pinch weld that runs along the bottom of the rocker panels on the vehicle. As the body styles have changed, the pinch weld has been shortened, relocated and in some instances eliminated, making it necessary to use a different attachment system for each vehicle style in order to hold the vehicle in a fixed position on the frame straightening rack. Although the vertical pinch weld remains a standard point for clamping on many vehicles, horizontal pinch welds and in some instances pinch welds set at an angle of 35 degrees from the vertical are being used. Each configuration requires a different attachment system. The introduction of the jack mount by Mercedes requires a specific type of system for securing the vehicle to the rack. Suspension pockets are used on some of the General Motors vehicles which require another type of head. Since each vehicle must be anchored at four separate points, a repair shop must inventory at least one attachment system for each type of vehicle. This can be costly and requires considerable storage place for each attachment system. US-A-4,898,019 discloses a vehicle support assembly for maintaining a vehicle in a stationary position during body straightening operation. The vehicle support assembly includes a universal base assembly comprising a base mounted on a stand, a slide mounted on the base, an attachment head adapted to be mounted on the slide and a screw rigidly locking the slide to the base. SUMMARY OF THE INVENTION The invention relates to a vehicle repair system as claimed in claim 1. A primary advantage of the present invention is a reduction in inventory which the repair shop requires in order to service the various types of vehicles. One set of mounting assemblies is all that is required for each repair shop and one set of attachment heads for each type automobile. In accordance with one aspect of the present invention, a simple and economical base assembly is provided which is compatible with each of the various attachment heads required for the various vehicles. Other principal features and advantages of the invention will become apparent to those skilled in the art upon review of the following drawings, the detailed description and the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EXEMPLARY EMBODIMENTS As seen in Figure 1, the attachment system includes a number of mounting assemblies 10 shown mounted on a rack 12 and connected to a pinch weld 14 on one side of an automobile generally shown at 16 by means of an attachment head 15. Four mounting assemblies 10 are required to securely anchor the automobile to the rack 12. A chain straightener assembly 18 is shown mounted on one end of rack 12. The mounting assembly 10 includes a mounting stand 20 and a universal base assembly 28. It should be noted that the stand 20 includes a base plate 22 which can be secured to various places on the rack 12 by clamps (not shown) to thereby accommodate various types of body styles. A column 21 is secured to the top of the base plate 22 and includes a sleeve 24 mounted in a generally parallel relation to the rack. A pair of anti-rotational tabs 26 are provided on the end of sleeve 24. The universal base assembly 28 is mounted on the sleeve 24 for securing the various attachment heads to a vehicle. The base assembly 28 includes a base 29 and a slide 50. The base 29 includes a plate 30 having a pair of angle members 32 mounted on each side of the top of the plate 30, forming a dovetail slot 33. A bracket 34 having a cylindrical opening 35 is secured to the bottom of the plate 30. A cylinder 36 is mounted in the opening 35. Means are provided for aligning the cylinder 36 in sleeve 24. Such means is in the form of notches 38 provided on each side of the cylinder 36. The base 29 is secured to the column 21 by means of a tube 40 having a head 42 at one end and a slot 44 in the other end. A pin 46 is provided at the end of slot 44. The tube 40 is inserted into the opening 35 in bracket 34 and into the sleeve 24. A wedge 48 is inserted into the slot 44 between the pin 46 and the column 21 to draw the notches 38 in cylinder 36 into engagement with tabs 26 on the end of sleeve 24. The slide 50 generally includes a plate 68 for supporting one of the various attachment devices, i.e., vertical 52, offset angle 54, horizontal (not shown) and jack mount 58. The slide 50 includes a slide plate 60 having an angular recess on each side which forms a dovetail slide 64 that matingly engages the dovetail slot 33 in plate 30. It should be noted that the slide 50 is moveable with respect to the plate 30 and is locked to the plate 30 by means of a screw 66 provided on the slide 50. This allows for a small amount of lateral movement to properly align the attachment head with the vehicle. The screw 66 is seated on one of the dovetail members 32 when properly aligned. The attachment heads are secured to a plate 68 which is vertically mounted on the top of the slide plate 60. The attachment heads are secured to a plate 68 which is reinforced by a fillet 70. A pair of through holes 72 are provided in plate 68. One of the various attachment heads 15 are secured to the plate 68 by means of bolts 77 depending on the type of body style. In this regard, the vertical attachment head 52 (Figs. 2, 4, and 5) generally includes a base plate 72 and a clamp plate 74. The base plate 72 includes two pairs of holes 73 and 75. The clamp plate 74 includes a pair of threaded holes 78. The clamp plate 74 is mounted on the base plate 72 by means of a pair of bolts 76 which pass through holes 73 and are threadedly received in threaded holes 78. A spring 80 may be provided on bolt 76 between plates 72 and 74 to bias the plates to an open position. Means are provided between the plates to engage a pinch weld 82 as shown in Figure 5. Such means is in the form of a serrated strip 86 mounted in a groove 84 in each plate 72, 74. The plates 72 and 74 are closed with sufficient force to seat the serrated strips 86 firmly on the pinch weld. The base plate 72 is secured to the plate 68 by bolts 77. The offset angle attachment head 54 (Figs. 6, 9, and 10) generally includes a base plate 88 and a clamp plate 90. The base plate 88 includes an angularly offset portion 92 which corresponds to the angle of the pinch weld 95 (35°), a pair of threaded holes 96 and a pair of mounting holes 98. The clamp plate 90 includes a pair of holes 100 and is secured to the offset portion 92 by bolts 102. The jack mount attachment head 58 (Figs. 6 and 7) is used on vehicles having built-in jack mount type fixtures 104 permanently mounted on the vehicle. Each fixture 104 includes a mounting hole 106 on the side of the vehicle. The jack mount attachment 58 includes a base plate 108 having an angularly offset portion 110 and a pair of mounting holes 112. A locating pin 114 is provided in the offset portion 110 for engaging the hole 106 in fixture 104. Thus, it should be apparent that there has been provided in accordance with the present invention a universal base member for securing vehicles for damage repair that fully satisfies the aims and advantages set forth above.
