Low rider wheel jack

摘要

A jack apparatus is provided for lifting a low rider vehicle, even though the vehicle has very low ground clearance. The jack apparatus includes interfitting upper and lower subframes supported by a scissor lift. The upper subframe includes opposing parallel arms shaped to fit within a generally triangular cavity defined by the vehicle's tire and sheet metal and ground surface, such that the jack apparatus can engage the vehicle's tire and lift the vehicle without violating the generally triangular cavity, thus leading to a safer and better system for lifting the low rider without potentially damaging vehicle's sheet metal components. The jack apparatus includes width-adjustable arms and legs for flexible use, which are removable or collapsible to a very low shape for compact storage. Also, the upper subframe includes a table, allowing it to lift an ATV or motorcycle.

主权项

1. A jack apparatus adapted to lift a low rider vehicle having components defining a ground clearance of less than 2 inches vertically and that define with vehicle tires a generally triangular low clearance space, comprising:
an upper subframe having a pair of horizontally-adjustable lift arms adapted to extend into the low clearance space and engage front and rear surfaces of the tire; a lower subframe having a pair of ground-engaging legs configured to fit into the low clearance space with the lift arms and that are located generally under the lift arms when the lift arms are raised; the lower subframe including at least one horizontal beam mount comprising a slot, the horizontal beam mount extending substantially perpendicular on at least one side of the lower subframe and wherein the pair of ground-engaging legs include a slot engaging fastener for engaging the slot of the horizontal beam mount for laterally adjusting the ground engaging legs on the horizontal beam mount; and a scissor lift mechanism attached between the upper and lower subframes but not located under the lift arms so that the lift mechanism operates from a position outboard of the vehicle; the scissor lift mechanism including a first upper axle rotatably secured to the upper subframe on a vehicle-adjacent lift-arm-adjacent side of the upper subframe and including a first lower axle rotatably secured to the lower subframe on a vehicle-adjacent lift-arm-adjacent side of the lower subframe; the lift arms being movable between a fully-collapsed lowest position where the arms are each laterally adjacent the associated legs, and movable to vertically lifted positions above the lowest position; and the scissor lift mechanism including a threaded screw attached horizontally to the upper subframe and that moves with and remains constantly horizontally adjacent the upper subframe when operating the lift mechanism between lower-most and raised positions.
