Abstract

The present invention, in one or more embodiments, provides a jack-positioning device of jack including a seating bottom and a loading table, where the jack-positioning device includes a base portion to support the seating bottom of the jack, an arm portion to connect the base portion, and a top portion to press against the loading table of the jack, and where the top portion along with the arm portion is to position the jack at a holding position, and the arm portion is rotatable relative to the base portion and the top portion. The jack-positioning device of the present invention may be employed to position the jack within a tight space in a relatively time efficient manner.

First claim

What is claimed is:

1. A jack-positioning device of a jack including a seating bottom and a loading table, the jack-positioning device comprising:
a base portion to support the seating bottom of the jack and include a base hook;
an arm portion to connect the base portion and include a base ring and a top ring; and
a top portion to press against the loading table of the jack and include a top hook,
wherein the top portion along with the arm portion is to position the jack at a holding position, and wherein the base hook is received in the base ring and the top hook is received in the top ring and the arm portion is rotatably connected to the base portion and the top portion.

2. The jack-positioning device of claim 1 , wherein the top portion includes a holding plate, the base portion includes a base plate, and the arm portion includes a first arm and a second arm separable from each other and connectable to at least one of the holding plate and the base plate.

3. The jack-positioning device of claim 1 , wherein the top portion includes a fastener for connecting the loading table to the top portion.

4. The jack-positioning device of claim 1 , wherein the arm portion includes a spring element so as to be tension-charged.

5. The jack-positioning device of claim 1 , further comprising a cushion to be positioned between the top portion and the loading table of the jack.

6. The jack-positioning device of claim 2 , wherein at least one of the first arm and second arm is rotatable in at least one direction about the holding plate.

7. The jack-positioning device of claim 2 , wherein at least one of the first arm and second arm is rotatable in at least one direction about the base plate.

8. The jack-positioning device of claim 2 , wherein at least one of the first arm and second arm is detachable from the holding plate.

9. The jack-positioning device of claim 2 , wherein at least one of the first arm and second arm is detachable from the base portion.

10. The jack-positioning device of claim 2 , wherein the top hook includes a first top hook extending from one end of the holding plate to form a hole with a cross-section thereof being a closed loop, and a second top hook extending from an opposing end of the holding plate to form a rib with a cross-section thereof being an open loop, and the top ring includes a first top ring formed by an integral extension of the first arm and the second top ring formed from an integral extension of the second arm, wherein the first top hook is received in the first top ring and the second top hook is received in the second top ring.

11. The jack-positioning device of claim 2 , wherein at least one of the first arm and the second arm includes a first section connectable to the base portion and include a first ring portion and a second section includes a second ring portion, wherein the first ring portion is interconnected with the second ring portion such that the second section is pivotable relative to the first section at least in a first direction and second direction different from the first direction.

12. The jack-positioning device of claim 2 , further comprising a third arm and a fourth arm, wherein at an assembled position, the second arm is spaced apart from the first arm in a first direction, and the fourth arm is spaced apart from the third arm in a second direction different from the first direction.

13. The jack-positioning device of claim 12 , wherein the base portion further includes first and second ears extending from the base plate to contact the first and second arms, respectively, and third and fourth ears extending from the base plate to contact the third and fourth arms, respectively.

14. A jack-positioning device for holding a jack that has a seating bottom and a loading table, the jack-positioning device comprising:
a base plate for supporting the seating bottom of the jack and include a first base hook and a second base hook;
a holding plate for pressing against the loading table of the jack and include a first top hook at one end and a second top hook at an opposite end;
a first arm and a second arm for connecting the base plate with the holding plate to create a space for holding the jack at a holding position, wherein the first arm includes a first base ring and a first top ring connected to the first base hook and the first top hook, respectively, and the second arm includes a second base ring and a second top ring connected to the second base hook and the second top hook, respectively such that the first arm and the second arm are rotatably connected to the to the base plate and the holding plate.

15. The jack-positioning device of claim 14 , wherein the first top hook forms a closed-loop from an extension of the holding plate and the second top hook forms an open-loop from an extension of the holding plate to allow detachment of the second top ring of the second arm from the holding plate.

16. The jack-positioning device of claim 15 , wherein the first top ring and the first base ring of the first arm is a natural and integral extension of the first arm, respectively, and the second top ring and the second base ring of the second arm is a natural and integral extension of the second arm, respectively.

17. The jack-positioning device of claim 14 , wherein at least one of the first and second arms has a spring element so as to be tension-charged.
