Abstract

Abstract A wheel-raising device comprising a base member, a ramp member joined at one end to the base member, a plurality of spaced-apart vertical supporting members positioned between the base and ramp, and a wheel-blocking member positioned on the ramp. The height to which the wheel is raised is adjustable in both relatively large and small ranges. The wheel-blocking member is releasably positioned at various locations along the ramp member, and the orientation of the blocking member at each location can be changed to vary the angle between the ramp and the wheelcontacting surface of the blocking member. The base, ramp, and supporting member can be fixedly attached to each other or, alternatively, pivotally connected whereby the device is collapsible for storage.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 200 words
A vehicle wheel raising device comprising: a. a base member adapted to be placed on a supporting surface, for example the ground; b. a ramp member connected at one end to said base member; c. a plurality of generally vertical supporting members extending between and positioned along said base and ramp members, said supporting members terminating at the upper ends thereof along a plane inclined with respect to said base member and arranged so that said ramp member is inclined with respect to said base member; and d. a wheel-blocking member having three sides which define at least two unequal included angles and provided on at least two sides thereof with two spaced-apart connecting means for releasable engagement with corresponding pairs of connecting means provided on and spaced along said ramp member, whereby said wheel-blocking member is releasably connected to said ramp member at any one of a number of spaced locations along the top surface thereof, and whereby said wheel-blocking member is adapted to be connected in different orientations at each location on said ramp member whereby the angle between the plane of said ramp and the plane of the wheel-contacting surface of said wheel-blocking member can be varied.
Claim 2
Dependent Claim 200 words
A vehicle wheel raising device comprising: a. a base member adapted to be placed on a supporting surface, for example the ground; b. a ramp member connected at one end to said base member; c. a plurality of generally vertical supporting members extending between and positioned along said base and ramp members, said supporting members terminating at the upper ends thereof along a plane inclined with respect to said base member and arranged so that said ramp member is inclined with respect to said base member; and d. a wheel-blocking member having three sides which define at least two unequal included angles and provided on at least two sides thereof with two spaced-apart connecting means for releasable engagement with corresponding pairs of connecting means provided on and spaced along said ramp member, whereby said wheel-blocking member is releasably connected to said ramp member at any one of a number of spaced locations along the top surface thereof, and whereby said wheel-blocking member is adapted to be connected in different orientations at each location on said ramp member whereby the angle between the plane of said ramp and the plane of the wheel-contacting surface of said wheel-blocking member can be varied.
Claim 3
Dependent Claim 44 words
The wheel-raising device as defined in claim 1 wherein said ramp member is fixedly attached at the one end to said base member and wherein each of said vertical supporting members is fixedly attached at corresponding ends thereof to said base and ramp member.
Claim 4
Dependent Claim 45 words
The wheel-raising device as defined in claim 2 wherein said base and ramp members each comprises a generally rectangular plate and wherein each of said vertical supporting members comprises a plate having a width substantially equal to the width of said base and said ramp.
Claim 5
Dependent Claim 42 words
The wheel-raising device as defined in claim 1 wherein said ramp member is pivotally connected at the one end to said base member and wherein each of said vertical supporting members is pivotally connected at one end thereof to said base member.
Claim 6
Dependent Claim 42 words
The wheel-raising device as defined in claim 4 wherein said ramp member is provided with stops on the underside thereof adapted to abut the other end of said supporting members and restrain further pivotal movemenT thereof when moved to a vertical position.
Claim 7
Dependent Claim 80 words
The wheel-raising device as defined in claim 4 wherein said base member comprises a generally rectangular plate and two upstanding flange members on opposite edges thereof, said ramp member comprises a generally rectangular plate having a width slightly less than that of said baseplate and pivotally connected to said upstanding flanges, and wherein each of said vertical supporting members comprises a plate having a width slightly less than the width of said baseplate and pivotally connected to said upstanding flanges.
Claim 8
Dependent Claim 50 words
The wheel-raising device as defined in claim 6 wherein each of said vertical supporting members is attached along one edge to a sleeve extending perpendicular to and between said flange members and wherein a pin extending through said sleeve is rotatably connected at opposite ends in each of said flanges.
Claim 9
Dependent Claim 190 words
A vehicle wheel raising device comprising: a. a base member adapted to be placed on a supporting surface, for example the ground; b. a ramp member connected at one end to said base member; c. a plurality of vertical supporting members extending between and spaced along said base and ramp members, said supporting members being of unequal height and arranged so that said ramp member is inclined with respect to said base member; and d. a wheel-blocking member having three sides which define at least two unequal included angles and wherein at least two sides of said wheel-blocking member are provided with two spaced-apart lugs projecting therefrom, said ramp member being provided with corresponding pairs of apertures being spaced along said ramp member, whereby said wheel-blocking member is releasably connected to said ramp member at any one of a number of spaced locations along the top surface thereof, and said wheel-blocking member is adapted to be connected in different orientations at each location on said ramp member whereby the angle between the plane of said ramp and the plane of the wheel-contacting surface of said wheel-blocking member can be varied.
Claim 10
Dependent Claim 190 words
A vehicle wheel raising device comprising: a. a base member adapted to be placed on a supporting surface, for example the ground; b. a ramp member connected at one end to said base member; c. a plurality of vertical supporting members extending between and spaced along said base and ramp members, said supporting members being of unequal height and arranged so that said ramp member is inclined with respect to said base member; and d. a wheel-blocking member having three sides which define at least two unequal included angles and wherein at least two sides of said wheel-blocking member are provided with two spaced-apart lugs projecting therefrom, said ramp member being provided with corresponding pairs of apertures being spaced along said ramp member, whereby said wheel-blocking member is releasably connected to said ramp member at any one of a number of spaced locations along the top surface thereof, and said wheel-blocking member is adapted to be connected in different orientations at each location on said ramp member whereby the angle between the plane of said ramp and the plane of the wheel-contacting surface of said wheel-blocking member can be varied.
