Abstract
Official abstract text for this publication.
A ramp structure for a mobile platform includes at least one ramp member structured to be operably coupled to the mobile platform. The at least one ramp member is structured to be deflectable toward a ground surface so as to form a ramp responsive to contact with a subject vehicle wheel when the ramp member is operably coupled to the mobile platform and the mobile platform resides on the ground surface. The ramp extends in a direction from the ground surface toward a top surface of the mobile platform.
First claim
Opening claim text (preview).
What is claimed is: 1. A ramp structure for a mobile platform, the ramp structure comprising at least one ramp member operably coupled to the mobile platform and structured to be deformable in a direction toward the ground surface so as to form a ramp responsive to contact of the at least one ramp member with a subject vehicle wheel when the at least one ramp member is operably coupled to the mobile platform and the mobile platform resides on the ground surface, the ramp extending in a direction from the ground surface toward a top surface of the mobile platform, wherein the at least one ramp member has an end portion structured to be contacted by the subject vehicle wheel and at least one roller element connected to the at least one ramp member end portion, wherein the at least one ramp member is structured to be deformable so as to enable the at least one roller element to contact the ground surface responsive to contact of the end portion by the subject vehicle wheel, and wherein the at least one roller element is structured to roll along the ground surface in a direction toward the mobile platform while supporting the at least one ramp member end portion as the at least one ramp member end portion is deflected toward the ground surface responsive to contact of the at least one ramp member end portion by the subject vehicle wheel, when the at least one ramp member is operably coupled to the mobile platform. 2. The ramp structure of claim 1 further comprising a mounting bracket structured to be attached to the mobile platform, and wherein each ramp member is coupled to the mounting bracket. 3. A guided test platform comprising: the mobile platform in accordance with claim 1 ; and a ramp structure in accordance with claim 1 operably coupled to the mobile platform. 4. A guided test platform comprising mobile platform and a ramp structure including a plurality of ramp members operably coupled to the mobile platform, each ramp member being structured to be individually rotatable about a common rotational axis toward a ground surface so as to form a portion of a ramp responsive to contact with the subject vehicle wheel when the mobile platform resides on the ground surface, the ramp extending in a direction from the ground surface toward a top surface of the mobile platform, the ramp structure further comprising at least one spring member spaced apart from the rotational axis and structured to resist a rotation of each ramp member toward the ground surface to form the portion of the ramp, and wherein the rotation of each ramp member toward the ground surface to form the portion of the ramp causes the ramp member to compress the at least one spring member so as to resist the rotation of the ramp member.
