Abstract

Abstract A horizontally disposed support adapted to support a damaged vehicle and formed so as to facilitate certain pulling and pushing operations on the vehicle body and its frame. The support is provided with an articulated mount at one end to permit said one end to be lowered to a loading position to facilitate placing a vehicle on the support. The articulated mount may then be actuated to raise said one end so that the support is exactly horizontal. The support is also provided with relatively heavy strength members formed to provide longitudinally extending and transversely extending slots in communication with each other thereby forming a passageway permitting an anchor member to be moved to any point on the support to resist relative heavy pulling forces in any desired direction.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 104 words
Apparatus for straightening vehicle bodies and frames comprising: a generally rectangular vehicle support, said support including a pair of relatively heavy longitudinally extending strength members and a pair of transversely extending strength members, the members of each of said pairs being spaced apart horizontally to define a slot therebetween with said slots in communication with each other at the intersection of said longitudinal and transverse pairs to define a passageway having two runs in intersecting and communicating relationship, and a hanger extending vertically within said passageway and adapted to slide at its upper end on said strength members to any point in said passageway.
Claim 2
Dependent Claim 104 words
Apparatus for straightening vehicle bodies and frames comprising: a generally rectangular vehicle support, said support including a pair of relatively heavy longitudinally extending strength members and a pair of transversely extending strength members, the members of each of said pairs being spaced apart horizontally to define a slot therebetween with said slots in communication with each other at the intersection of said longitudinal and transverse pairs to define a passageway having two runs in intersecting and communicating relationship, and a hanger extending vertically within said passageway and adapted to slide at its upper end on said strength members to any point in said passageway.
Claim 3
Dependent Claim 32 words
Apparatus according to claim 1 wherein a bridge structure is provided over said members at said intersection and rigidly secured thereto to compensate for the loss of strength due to said slot.
Claim 4
Dependent Claim 25 words
Apparatus according to claim 2 wherein said bridge structure includes an inverted channel secured along each flange to one member of one of said pairs.
Claim 5
Dependent Claim 23 words
Apparatus according to claim 3 wherein a flange of said channel is provided with an opening to permit movement of said hanger therethrough.
Claim 6
Dependent Claim 22 words
Apparatus according to claim 1 wherein a third strength member is provided with one of said pairs to define two parallel slots.
