Vehicle jack and adapter therefor
A vehicle jack includes a lift element, an operative element operably connected to the lift element to transition the lift element from a first position to a second position, where the first position differs in elevation from the second position, and an extension element affixed to the lift element. The extension element has a bottom side that establishes a stable interface with the lift element.
1. A vehicle jack, comprising:
a lift element;
an operative element operably connected to the lift element to transition the lift element from a first position to a second position, wherein the first position differs in elevation from the second position; and
an extension element affixed to the lift element, wherein the extension element comprises:
a body comprising:
a top side;
a first side connected to and extending downwardly from the top side,
a second side connected to and extending downwardly from the top side,
a front side connected to and extending downwardly from the top side;
a rear side connected and extending downwardly from the top side,
a first tab connected to a bottom of the front side and extending toward the rear side, and
a second tab connected to a bottom of the rear side and extending toward the front side,
wherein the first tab and the second tab define a bottom side that is adapted to be positioned atop the lift element,
a first attachment element associated with the first side of the body, and
a second attachment element associated with the second side of the body,
wherein the first attachment element and the second attachment element engage the lift element to secure the body to the lift element, thereby establishing a stable interface between the body and the lift element.
2. The vehicle jack of claim 1 , wherein the lift element comprises:
a base;
a lift plate with a top side defining a first area; and
a plurality of scissor elements connecting the base to the lift plate;
wherein the bottom side of the body defines a second area, and
wherein a ratio of the first area to the second area is between 0.8-1.2.
3. The vehicle jack of claim 2 , wherein the ratio is between 0.9-1.1.
4. The vehicle jack of claim 3 , wherein the ratio is between 0.95-1.05.
5. The vehicle jack of claim 4 , wherein the ratio is 1.0.
6. The vehicle jack of claim 2 ,
wherein the first attachment element and the second attachment element engage the lift plate to secure the body to the lift plate.
7. The vehicle jack of claim 6 , wherein the body includes a detent in a top side for engagement with a frame element on a vehicle.
8. The vehicle jack of claim 6 , wherein:
the first attachment element is attached to the first side of the body, and the second attachment is attached to the second side of the body.
9. The vehicle jack of claim 2 , wherein the operative element further comprises:
an eyelet;
a rod connected to the eyelet;
a first socket engaging a first end of the rod and the plurality of scissor elements; and
a second socket engaging a second end of the rod and the plurality of scissor element,
wherein rotation of the eyelet causes rotation of the rod,
wherein rotation of the rod causes the first and second sockets to move therealong, thereby causing the first and second sockets to move in relation to one another, and
wherein, as the first and second sockets move along the rod, the plurality of scissor elements cause the base and the lift plate to move in relation to one another.
10. The vehicle jack of claim 2 , wherein:
the plurality of scissor elements comprise a first scissor element, a second scissor element, a third scissor element, and a fourth scissor element, and
the plurality of scissor elements connect to one another to form a diamond shape.
11. The vehicle jack of claim 10 , wherein:
the first and second scissor elements connect at first ends to the base,
the first and second scissor elements connect at second ends to third ends of the third and fourth scissor elements, and
the third and fourth scissor elements connect at fourth ends to the lift plate.
12. The vehicle jack of claim 1 , wherein the lift element comprises at least one material selected from a group comprising steel, aluminum, alloys of aluminum, iron, alloys of iron, nickel, alloys of nickel, titanium, alloys of titanium, magnesium, alloys of magnesium, natural materials, composite materials, carbon fiber composite materials, ceramics, and plastics.
13. The vehicle jack of claim 1 , wherein the extension element comprises at least one material selected from a group comprising steel, aluminum, alloys of aluminum, iron, alloys of iron, nickel, alloys of nickel, titanium, alloys of titanium, magnesium, alloys of magnesium, natural materials, composite materials, carbon fiber composite materials, ceramics, and plastics.
14. The vehicle jack of claim 1 , wherein the operative element comprises at least one material selected from a group comprising steel, aluminum, alloys of aluminum, iron, alloys of iron, nickel, alloys of nickel, titanium, alloys of titanium, magnesium, alloys of magnesium, natural materials, composite materials, carbon fiber composite materials, ceramics, and plastics.
15. An extension element for a vehicle jack, comprising:
a body comprising:
a top side;
a first side connected to and extending downwardly from the top side,
a second side connected to and extending downwardly from the top side,
a front side connected to and extending downwardly from the top side;
a rear side connected and extending downwardly from the top side,
a first tab connected to a bottom of the front side and extending toward the rear side, and
a second tab connected to a bottom of the rear side and extending toward the front side,
wherein the first tab and the second tab define a bottom side defining a first area that is adapted to be positioned atop the lift element having a top side with a second area;
a first attachment element associated with the first side of the body; and
a second attachment element associated with the second side of the body;
wherein the first attachment element and the second attachment element engage the lift element to secure the body to the lift element, and
wherein the bottom side establishes a stable interface with the lift element.
16. The extension element of claim 15 , wherein a ratio of the first area to the second area is between 0.8-1.2.
