Abstract

Abstract The combination with a drive-on type motor vehicle lift having spaced runways, of means for lifting the front end of a motor vehicle and for supporting it free of the front wheels thereof to allow inspection and servicing of the vehicle front end, comprising a front end lift assembly extending between said runways, rollers on said assembly supported on rails carried on the adjacent edges of said runways to permit longitudinal travel of said assembly as a unit, and means for elevating said assembly into lifting contact with a front end underside configuration portion of said vehicle.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 181 words
Means for lifting the front end of a motor vehicle and for supporting it free of the front wheels thereof to allow inspection and servicing of the vehicle front end while the vehicle is supported on a drive-on type motor vehicle lift having spaced runways, comprising a front end lift assembly extending transversely between a pair of said runways, rollers on said assembly supported on rails carried on the adjacent edges of said runways to permit longitudinal travel of said assembly as a unit, and means for elevating a component of said front end lift assembly into lifting contact with a front end underside configuration portion of said vehicle, and means pivoting said front end lift assembly above its center of gravity whereby It is adapted to extend vertically and to partially project above said runways when the runways are in elevated position, and adapted to be folded horizontally below the upper edges of said runways by rolling contact with a supporting base and between them where the runways are lowered to permit the supported vehicle to move from the runways.
Claim 2
Dependent Claim 181 words
Means for lifting the front end of a motor vehicle and for supporting it free of the front wheels thereof to allow inspection and servicing of the vehicle front end while the vehicle is supported on a drive-on type motor vehicle lift having spaced runways, comprising a front end lift assembly extending transversely between a pair of said runways, rollers on said assembly supported on rails carried on the adjacent edges of said runways to permit longitudinal travel of said assembly as a unit, and means for elevating a component of said front end lift assembly into lifting contact with a front end underside configuration portion of said vehicle, and means pivoting said front end lift assembly above its center of gravity whereby It is adapted to extend vertically and to partially project above said runways when the runways are in elevated position, and adapted to be folded horizontally below the upper edges of said runways by rolling contact with a supporting base and between them where the runways are lowered to permit the supported vehicle to move from the runways.
Claim 3
Dependent Claim 36 words
The device of claim 1 wherein the elevatable component of said assembly comprises a plurality of manually elevatable hook elements horizontally pivoted thereon and adapted to contact said front end underside configuration portions of said vehicle.
Claim 4
Dependent Claim 18 words
The device of claim 2 wherein said hook elements are slidable longitudinally of said assembly between said runways.
Claim 5
Dependent Claim 17 words
The device of claim 2 wherein said hook elements are further rotatably retained on vertically extending pivots.
Claim 6
Dependent Claim 225 words
The combination with a drive-on type motor vehicle lift having spaced runways, of means for lifting the front end of a motor vehicle and for supporting it free of the front wheels thereof to allow inspection and servicing of the vehicle front end while the vehicle is supported comprising a front end lift assembly extending transversely between said runways, rollers on said assembly supported on rails carried over the adjacent edges of said runways to permit longitudinal travel of said front end lift assembly as a unit, means for pneumatically elevating the components of said assembly into lifting contact with a front end underside configuration portion of said vehicle, the elevatable components of said assembly comprising a plurality of manually elevatable horizontally and vertically pivoted hook elements adapted to contact said front end underside configuration portions of said vehicle, and means retaining said hook elements slidable longitudinally of said assembly between said runways, said front end lift assembly being pivoted to said runways above its center of gravity and adapted to extend vertically and to partially project above said runways when the runways are in elevated position, and adapted to be folded horizontally below the upper edges of said runways and between them when the runways are lowered into contact with a supporting surface and to permit the supported vehicle to move from the runways.
Claim 7
Dependent Claim 225 words
The combination with a drive-on type motor vehicle lift having spaced runways, of means for lifting the front end of a motor vehicle and for supporting it free of the front wheels thereof to allow inspection and servicing of the vehicle front end while the vehicle is supported comprising a front end lift assembly extending transversely between said runways, rollers on said assembly supported on rails carried over the adjacent edges of said runways to permit longitudinal travel of said front end lift assembly as a unit, means for pneumatically elevating the components of said assembly into lifting contact with a front end underside configuration portion of said vehicle, the elevatable components of said assembly comprising a plurality of manually elevatable horizontally and vertically pivoted hook elements adapted to contact said front end underside configuration portions of said vehicle, and means retaining said hook elements slidable longitudinally of said assembly between said runways, said front end lift assembly being pivoted to said runways above its center of gravity and adapted to extend vertically and to partially project above said runways when the runways are in elevated position, and adapted to be folded horizontally below the upper edges of said runways and between them when the runways are lowered into contact with a supporting surface and to permit the supported vehicle to move from the runways.
