Abstract
A lift assembly connects to a receiver hitch and utilizes a plurality of parallel arms connecting a vertical mounting post to a center support in a lift frame that is raised and lowered by the lift assembly. The lift assembly is configured so that the parallel arms rotate from vertical to an inclined angle as the lift frame is lowered, but the arms do not extend below the horizontal as they extend rearward from the mounting post.
Claims22
A vehicle mounted lift assembly comprising a mounting portion attached to the rear of a vehicle, at least first and second parallel arms extending from the mounting portion to a lift frame, the lift frame further defining a forward plane, wherein the first and second parallel arms extend upward in a nearly vertical orientation within the forward plane when the lift frame is in a raised position and wherein the first and second parallel arms extend rearward outward from the mounting portion in an upward orientation when the lift frame is in a fully lowered position and
- said first parallel arm having a first bottom end secured at a first retaining mounting axis on the mounting portion and extending to a first top end secured at a first retaining frame axis on the lift frame, and said second parallel arm having a second bottom end secured at a second retaining mounting axis directly rearward of the first retaining mounting axis on the mounting portion and extending to a second top end secured at a second retaining frame axis rearward of the first retaining frame axis on the lift frame.
A vehicle mounted lift assembly comprising:
- a horizontal attaching member received in a hitch receiver at the rear of a vehicle and secured to a vertical post having an upper and a lower end;
- a first arm having a first bottom ends fastened by a first bottom retaining axis on a lower portion of the vertical post and a first opposite ends fastened by a first top retaining axis to a support section of a lift frame;
- a second arm having a second bottom end fastened by a second bottom retaining axis on the lower portion of the vertical post rearward of the first bottom retaining axis, and a second opposite end fastened by a second top retaining axis to a support section of the lift frame rearward of the first top retaining axis;
- wherein, when the lift frame is in a raised position, the first and second arms extend vertically upward, substantially in alignment with the vertical post and when the lift frame is in its fully lowered position, the first and second arms extend rearward from the vertical post at an upward angle.
A vehicle mounted lift assembly comprising:
- a horizontal attaching member received in a hitch receiver at the rear of a vehicle and secured to an arm mounting member;
- a first arm having a first mounting end fastened by a first mounting retaining axis on a portion of the arm mounting member and an opposite first frame end fastened by first frame retaining axis to a support section of a lift frame;
- a second arm having a second mounting end fastened by a second mounting retaining axis on a portion of the arm mounting member directly rearward of the first mounting retaining axis, and an opposite second frame end fastened by a second frame retaining axis to the support section of the lift frame rearward of the first frame retaining axis;
- wherein, when the lift frame is in a raised position, the first and second arms extend vertically upward, and when the lift frame is in its fully lowered position, the first and second arms extend rearward from the arm mounting member to the support section of the lift frame at an upward angle at least about 25 degrees above the horizontal.
