Lift system

摘要

Embodiments of the invention comprise a self-supporting platform style lift system operating from a transport position to a lifting position for assisting in egress and ingress from a vehicle. In a lifting position, a platform member extends from a rotating frame capable of axial rotation about a vehicle frame. A ground frame, lifting frame, and platform frame system allow the platform member to be raised and lowered to the vehicle. The point at which the platform frame and lifting frame make contact with the ground provides support for applied loads on the platform member, thereby reducing stress and strain on the frame of a vehicle. In a transport position, the platform member extends parallel with the face of the vehicle.

主权项

1. A self-supporting platform style lift system to assist in ingress and egress from a vehicle comprising:
a. a platform member forming a resting surface, having a front end and a back end; b. a rotating frame mounted to a vehicle frame wherein said rotating frame is capable of axial rotation at one end of said rotating frame in relation to said vehicle frame; c. a ground frame comprising at least one individual support member, wherein said at least one individual support member extends perpendicular from said rotating frame; d. a lifting frame rotatably fastened at one end of said lifting frame to said rotating frame, and rotatably fastened at another end of said lifting frame to said back end of said platform member; e. a platform support frame system comprising a lower support member and a pivot member, wherein said lower support member is rotatably fastened at one end of said lower support member to said lifting frame, and rotatably fastened at another end of said lower support member to said pivot member, and wherein said pivot member is rotatably fastened at one end of said pivot member to said lower support member, and wherein said pivot member is rotatably fastened at another end of said lower support member to said back end of said platform member; f. a ground frame lifting arrangement, wherein activation of said ground frame lifting arrangement allows for axial rotation of said rotating frame with respect to said vehicle frame; and g. a platform member lifting arrangement, wherein activation of said platform member lifting arrangement causes said lifting frame to axially rotate in relation to said ground frame, thereby causing said platform support frame system and said platform member to axially rotate in relation to said vehicle.
