Stacking base system for temporary posts

1. A stacking base system for transporting to a work site to support a plurality of posts in a substantially vertical orientation, the system comprising:

a plurality of hollow base members, wherein each base member:

defines a fill port and includes a port plug adapted to be removably inserted in the fill port;

defines a post aperture extending downward through the base member from an upper surface thereof to a lower surface thereof, the post aperture shaped to correspond to a cross-section of the posts;

comprises three legs extending down from outer edges of the lower surface of each base member, the legs substantially equally spaced around the lower surface of the base member, and substantially equally spaced from the post aperture; and

wherein the post aperture is oriented substantially vertically when bottom ends of the legs are resting on a substantially horizontal surface;

wherein the base members are stacked such that a top portion of a lower base member engages a bottom portion of a next adjacent upper base member and such that the plurality of base members forms a base stack; and

wherein the upper surface of each base member defines a stacking lug above each leg, and wherein a bottom surface of each leg defines a bottom recess, and wherein the stacking lug of the lower base member is slidingly engaged in the bottom recess of the next adjacent upper base member.

2. The system of claim 1 wherein each base member is substantially triangular, and wherein each leg extends downward at a corner of the substantially triangular base member.

3. The system of claim 2 wherein the upper surface of each base member defines a top recess along perimeter edges of each corner, and wherein the stacking lug is formed inside the top recess.

4. The system of claim 2 wherein the fill port of each base member is defined in an outer side edge of one of the corners of the base member.

5. The system of claim 1 wherein each base member defines at least one stake aperture extending downward through the base member from the upper surface thereof to the lower surface thereof.

6. A stacking base system for transporting to a work site to support a plurality of posts in a substantially vertical orientation, the system comprising:

a plurality of hollow base members, wherein each base member:

defines a fill port and includes a port plug adapted to be removably inserted in the fill port;

defines a post aperture extending downward through the base member from an upper surface thereof to a lower surface thereof, the post aperture shaped to correspond to a cross-section of the posts;

comprises three legs extending down from outer edges of the lower surface of each base member, the legs substantially equally spaced around the lower surface of the base member, and substantially equally spaced from the post aperture; and

wherein the post aperture is oriented substantially vertically when bottom ends of the legs are resting on a substantially horizontal surface;

wherein the base members are stacked such that a top portion of a lower base member engages a bottom portion of a next adjacent upper base member and such that the plurality of base members forms a base stack;

wherein a base sleeve extends above the upper surface of each base member and wherein an inner surface of the base sleeve is aligned with inner walls of the post aperture; and

wherein the base sleeve extends substantially from the upper surface of the lower base member to the lower surface of the next adjacent upper base member.

7. A stacking base system for transporting to a work site to support a plurality of posts in a substantially vertical orientation, the system comprising:

a plurality of hollow base members, wherein each base member:

defines a fill port and includes a port plug adapted to be removably inserted in the fill port;

defines a post aperture extending downward through the base member from an upper surface thereof to a lower surface thereof, the post aperture shaped to correspond to a cross-section of the posts;

comprises three legs extending down from outer edges of the lower surface of each base member, the legs substantially equally spaced around the lower surface of the base member, and substantially equally spaced from the post aperture; and

wherein the post aperture is oriented substantially vertically when bottom ends of the legs are resting on a substantially horizontal surface;

wherein the base members are stacked such that a top portion of a lower base member engages a bottom portion of a next adjacent upper base member and such that the plurality of base members forms a base stack; and

wherein each base member includes an internal crush brace extending from a bottom wall thereof to a top wall thereof inside a hollow interior thereof.

8. A stacking base system for transporting to a work site to support a plurality of posts in a substantially vertical orientation, the system comprising:

a plurality of hollow base members, wherein each base member:

defines a fill port and includes a port plug adapted to be removably inserted in the fill port;

defines a post aperture extending downward through the base member from an upper surface thereof to a lower surface thereof, the post aperture shaped to correspond to a cross-section of the posts;

comprises three legs extending down from outer edges of the lower surface of each base member, the legs substantially equally spaced around the lower surface of the base member, and substantially equally spaced from the post aperture; and

wherein the post aperture is oriented substantially vertically when bottom ends of the legs are resting on a substantially horizontal surface;

wherein the base members are stacked such that a top portion of a lower base member engages a bottom portion of a next adjacent upper base member and such that the plurality of base members forms a base stack; and

a stacking cord support assembly comprising a plurality of cord caps, a lower portion of each cord cap defining a post recess shaped to correspond to a cross-section of the posts, and prongs extending from an upper portion thereof; and wherein the cord caps are stacked such that a top portion of a lower cord cap engages a bottom portion of a next adjacent upper cord cap.

9. The system of claim 8 wherein each cord cap comprises a cap sleeve extending downward and defining the post recess, and wherein a sleeve recess is defined between the prongs, and wherein the sleeve recess of the lower cord cap is substantially filled by the cap sleeve of the next adjacent upper cord cap.
