Abstract

A trailer jack support apparatus configured to support trailer hitches includes a monolithic block having six sides with the trailer jack support being in the shape of a square frustrum or trapezoid. The top of the trailer jack support includes a number of protrusions which extend from the trailer jack support. Further, the top side has a recess and a void located at the bottom of the recess. In addition, the bottom of the trailer jack support includes numerous recesses defined therein and may engage with the protrusions extending from the top of a second trailer jack support.

Claims (64)

1 . A trailer jack support apparatus comprising:

a block having six sides;

a recess defined in a top side, the recess including a void defined therein; and

a plurality of protrusions extending from the top side, at least one of the plurality of protrusions being positioned to extend from the top side proximate a corner of the top side of the block and separated, by a planar portion of the top side of the block, from another of the plurality of protrusions proximate another corner of the top side of the block;

wherein at least a portion of the planar portion of the top side of the block extends to an edge of the top side; and

wherein the void defined in the recess of the top side comprises:

a rectangular void defined in the top side, the rectangular void dimensioned to accept a rectangular stabilizer, a rectangular foot, or combinations thereof,

at least one half-moon void defined in the top side, the half-moon void dimensioned to accept a caster, a wheel, or combinations thereof,

a circular void defined in the top side, the circular void dimensioned to accept a pipe, a circular stabilizer, a circular foot, or combinations thereof, or

combinations thereof.

2 . The trailer jack support apparatus according to claim 1 , wherein the block further comprises:

a first side;

a second side opposite the first side;

a third side; and

a fourth side opposite the third side, wherein the first side and the second side are shorter in length relative to the third side and the fourth side.

3 . The trailer jack support apparatus according to claim 1 , wherein at least one of the recess, the plurality of protrusions, protrusion, or combinations thereof is formed in the block to be monolithic with the block.

4 . The trailer jack support apparatus according to claim 1 , wherein the block is made of recycled plastic.

5 . The trailer jack support apparatus according to claim 1 , wherein the plurality of protrusions extending from the top side comprises:

a first notch defined in a first protrusion of the at least two protrusions; and

a second notch defined in a second protrusion of the at least two protrusions, wherein the first notch and the second notch face the recess defined in the top side to align a rectangular stabilizer, a rectangular foot, or combinations thereof between the at least two protrusions.

6 . The trailer jack support apparatus according to claim 1 , further comprising at least one engagement recess defined in a bottom side of the block dimensioned to correspond to a dimension of the protrusion.

7 . The trailer jack support apparatus according to claim 1 , wherein:

the block is a first block,

the trailer jack support apparatus comprises a second block, and

the at least two protrusions extend from the top side of the first block to engage with the at least two protrusion recesses defined in the bottom side of the second block such that the second block stacks on and engages with the first block.

8 . An apparatus comprising:

a square frustum;

a recess defined in a top side, the recess including a void defined therein; and

a plurality of protrusions extending from the top side, at least one of the plurality of protrusions being positioned to extend from the top side proximate a corner of the top side of the block and separated, by a planar portion of the top side of the block, from another of the plurality of protrusions proximate another corner of the top side of the block;

wherein the void defined in the recess of the top side comprises at least one of a rectangular void defined in the top side, at least one half-moon void defined in the top side, and a circular void defined in the top side; and

wherein the protrusion extending from the top side comprises:

four protrusions extending from the top side; and

a notch defined in at least one of the four protrusions, wherein the notch faces the recess defined in the top side to align a rectangular stabilizer, a rectangular foot, or combinations thereof between the four protrusions.

9 . The apparatus according to claim 8 , wherein the square frustum is made of plastic.

10 . The apparatus according to claim 8 , wherein at least one of the recess, the protrusion, or combinations thereof is formed in the frustum to be monolithic with the frustum.

11 . The apparatus according to claim 8 , wherein the square frustum further comprises:

a first side;

a second side opposite the first side;

a third side;

a fourth side opposite the third side;

the top side; and

a bottom side, wherein the top side of the square frustum comprises a smaller perimeter than a perimeter of the bottom side.

12 . The apparatus according to claim 8 , further comprising at least one engagement recess defined in a bottom side of the square frustum dimensioned to correspond to a dimension of one or more of the plurality of protrusions.

13 . The apparatus according to claim 8 , wherein: the square frustum is a first square frustum, and the apparatus further comprises: a second square frustum, wherein a bottom side of the second square frustum engages with the top side of the first square frustum.

14 . A trailer jack support system comprising:

a block;

a recess defined in a top side of the block, the recess including at least one void defined therein: and

a plurality of protrusions extending from the top side of the block, at least one of the plurality of protrusions being positioned to extend from the top side proximate a corner of the top side of the block and separated, by a planar portion of the top side of the block, from another of the plurality of protrusions proximate another corner of the top side of the block;

wherein the plurality of protrusions are provided in an arrangement configured to align an object between the protrusions; and

further comprising:

four protrusions, of the plurality of protrusions, extending from the top side;

a notch defined in at least one of the four protrusions, wherein the notch faces the recess defined in the top side to align a rectangular stabilizer, a rectangular foot, or combinations thereof between the four protrusions; and

an engagement recess defined in a bottom side of the block dimensioned to correspond to a dimension of the protrusion.

15 . A trailer jack support system comprising:

a block;

a recess defined in a top side of the block, the recess including at least one void defined therein; and

a plurality of protrusions extending from the top side of the block, at least one of the plurality of protrusions being positioned to extend from the top side proximate a corner of the top side of the block and separated, by a planar portion of the top side of the block, from another of the plurality of protrusions proximate another corner of the top side of the block;

wherein the plurality of protrusions are provided in an arrangement configured to align an object between the protrusions; and

wherein the void defined in the recess of the top side comprises:

a rectangular void defined in the top side, the rectangular void dimensioned to accept a rectangular stabilizer, a rectangular foot, or combinations thereof,

at least one half-moon void defined in the top side, the half-moon void dimensioned to accept a caster, a wheel, or combinations thereof,

a circular void defined in the top side, the circular void dimensioned to accept a pipe, a circular stabilizer, a circular foot, or combinations thereof, or

combinations thereof.

16 . The trailer jack support system according to claim 14 , wherein at least one of the recess, the four protrusions, or combinations thereof is formed in the block to be monolithic with the block.
