Abstract
Abstract An automotive service ramp comprising a unitary body member including a ramp portion with integral side stiffening, tire retaining rails, a contoured rest portion to receive the tire of an automobile, and an extension beyond the rest portion which constitutes a leg portion. The ramp portion has transverse corrugations, is contoured transversely to match normal tire cross sections and has depending stiffening sides. A slight edge rail extends above the surface of the ramp. A handle is pivotally secured to the body in a position whereby it may be grasped to carry the ramp with the ramp portion hanging downward. The handle is pivoted to overlie the rest and leg portion when not in use and to be out of the way. An integral retainer portion of the body member holds the handle at a fixed position when not in use. The handle is so contoured that if it is left in an unsecured position and an automobile wheel ascends the ramp, the tire snaps the handle into its stored position without damage either to the handle or to the tire. The handle and the retainer portions cooperate whereby movement of the handle into its stored position produces an identifiable sound to inform the user that the handle is in place.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations, and a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinal ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; and wherein said rest portion is a surface that is in the form of a portion of a sphere.
Claim 2
Dependent Claim
129 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations, and a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinal ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; and wherein said rest portion is a surface that is in the form of a portion of a sphere.
Claim 3
Dependent Claim
148 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations, and a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinal ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; including handle means pivotally secured to said ramp in the rest portion; wherein said handle is positioned whereby the movement of a tire on to the rest portion of said ramp moves said handle to a stored position.
Claim 4
Dependent Claim
148 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations, and a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinal ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; including handle means pivotally secured to said ramp in the rest portion; wherein said handle is positioned whereby the movement of a tire on to the rest portion of said ramp moves said handle to a stored position.
Claim 5
Dependent Claim
139 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations; a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinals ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; including handle means pivotally secured to said ramp in the rest portion; wherein said handle means includes a portion engagable with an audible sound upon movement to a stored position.
Claim 6
Dependent Claim
139 words
An automobile service ramp comprising a unitary sheet metal body member including a ramp portion, a wheel rest portion and a support portion; said ramp portion having a concave track portion having a number of transverse extending corrugations; a pair of integral ribs extending longitudinally with respect to said ramp portion along each side thereof; said longitudinal ribs upstanding above the level of the transverse corrugations and said longitudinal ribs including depending extensions constituting continuations of said longitudinals ribs having a length below the neutral fiber of a cross section of the ramp portion at least three times the maximum distance of the longitudinal rib above the neutral fiber; including handle means pivotally secured to said ramp in the rest portion; wherein said handle means includes a portion engagable with an audible sound upon movement to a stored position.
Claim 7
Dependent Claim
