Vehicle frame measurement device

Claim 1

A vehicle body-and-frame measurement apparatus for use in realigning the entire structure of a damaged unibody vehicle having reference points when the vehicle is supported on ramps, the ramps having a longitudinal axis and a horizontal plane, the apparatus comprising means for measuring the lower portion of the vehicle body-and-frame comprising: (a) at least two elongated rails to be supported by the ramps without fixably securing the rails to the ramps, the rails to be supported by the ramps substantially parallel to the longitudinal axis of the ramps; (b) cross-members between the rails for holding the rails in fixed parallel relationship relative to each other; (c) a plurality of reference members retained by the rails and means for slideably securing the reference members to the rails so that the reference members can slide along the longitudinal axis of the rails and can slide horizontally perpendicular to the rails; (d) at least two slideable vertical locators for each of at least two of the reference members slideably retained on the respective reference members, the locators being sufficiently long to reach reference points of the vehicle; (e) means for fixably securing each vertical locator to its respective reference member; (f) a pair of vertical uprights supported by the rails and having a vertical axis substantially perpendicular to the horizontal plane of the ramps; (g) a vertically adjustable horizontal bar slideably attached to the uprights for positioning above the vehicle frame or within the passenger compartment with the windows open, substantially perpendicular to both the longitudinal axis of the ramps and the vertical axis of the uprights; (h) means for affixing the horizontal bar to the uprights so that the bar is vertically adjustable; (i) at least to upper vertical locators slideably attached to the horizontal bar; (j) a rigid tram rail having at least one scale, the tram being attached to the horizontal bar, the bar being substantially parallel to the longitudinal axis of the rails and perpendicular to the horizontal bar; (k) means for affixing the tram rail to the horizontal bar so that the tram rail can slide along the length of the horizontal bar; and (l) a vertical locating base including a vertical locator slideably attached to the tram rail, the base being movable along the longitudinal axis of the tram rail.

Claim 5

An apparatus for attaching a damaged vehicle frame-and-body to a ramp of a vehicle frame straightening apparatus comprising: (a) a pair of anchor bars, each bar being longer in length than the width of the ramp, the bars being parallel to each other and adapted for positioning on top of the ramp; (b) a pair of end-bars slideable beneath the ramp with one end-bar at each end of the anchor bar; (c) fastening means for holding the end-bars to the anchor bars with the ramp clamped therebetween; (d) a clamp base insertable between the ramp and the anchor bars, the clamp base being slideable across the width of the ramp when the fastening means are loosened and the clamp base being fixed in position between the ramp and the anchor bar when the fastening means are tightened; and (e) vehicle clamping means supported by the clamp base for attachment to a damaged vehicle frame.

Claim 6

An apparatus for attaching a damaged vehicle frame-and-body to a ramp of a vehicle frame straightening apparatus comprising: (a) a pair of anchor bars, each bar being longer in length than the width of the ramp, the bars being parallel to each other and adapted for positioning on top of the ramp; (b) a pair of end-bars slideable beneath the ramp with one end-bar at each end of the anchor bar; (c) fastening means for holding the end-bars to the anchor bars with the ramp clamped therebetween; (d) a clamp base insertable between the ramp and the anchor bars, the clamp base being slideable across the width of the ramp when the fastening means are loosened and the clamp base being fixed in position between the ramp and the anchor bar when the fastening means are tightened; and (e) vehicle clamping means supported by the clamp base for attachment to a damaged vehicle frame.
