Abstract

A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

Claims

1. A sleeve assembly for a post, comprising:

a body of a material that is substantially impervious to water;

a cavity extending longitudinally within the body;

an upper aperture extending in the body to a first end of the cavity;

a plurality of standoff elements extending inward from inner walls of the cavity, an innermost surface of each of the plurality of standoff elements defining, a respective portion of an inner space within the cavity;

a lower aperture extending in the body from a second end of the cavity to an exterior of the body;

a plurality of drain channels within the cavity configured to permit fluid to flow through and exit the body via the lower aperture while the innermost surface of each of the standoff elements is in contact with a surface of a post positioned in the cavity; and

a first plurality of stops, each extending inward from an inner wall of the cavity without extending into the inner space beyond the innermost surface of an adjacent one of the plurality of standoff elements, and having a bearing surface lying substantially in a first plane, the first plane lying perpendicular to the longitudinal axis of the cavity.

2. The sleeve assembly of claim 1, further comprising an identification plate coupled to the body.

3. The sleeve assembly of claim 1, further comprising a drain tube having first and second ends, the first end being coupled to the second aperture such that fluid exiting the cavity passes into the drain tube.

4. The sleeve assembly of claim 1, further comprising a socket positioned within the cavity and configured to receive a bottom end of a post of the selected size.

5. The sleeve assembly of claim 4 wherein the socket is one of a plurality of sockets positioned in the cavity near the second end thereof and arranged concentrically on a longitudinal axis of the body, each configured to receive a bottom end of a post having either a different size or a different shape.

6. The sleeve assembly of claim 5 wherein the plurality of drain channels includes a plurality of gutters extending across each of the plurality of sockets so as to permit a flow of fluid between the cavity and the second aperture regardless of the presence of a post in one of the sockets.

7. The sleeve assembly of claim 1, further comprising:

a threaded aperture extending from an outer surface of the body to the cavity, and having a longitudinal axis lying perpendicular to a longitudinal axis of the cavity; and

a fastener having threads engaged by threads of the threaded aperture, the fastener substantially traversing the threaded aperture and being configured to move along the longitudinal axis of the threaded aperture.

8. The sleeve assembly of claim 1 wherein the body is of reinforced concrete.

9. The sleeve assembly of claim 8, further comprising a sleeve liner positioned within the body, inner surfaces of the sleeve liner substantially defining the inner surfaces of the cavity, including the pluralities of standoff elements and drain channels.

10. The sleeve assembly of claim 9 wherein the sleeve liner comprises two substantially identical liner sections of injected-molded plastic.

11. The sleeve assembly of claim 1 wherein the inner space collectively defined by the innermost surfaces of the plurality of standoff elements has substantially the lateral dimensions of a 4×

4 post extending longitudinally within the cavity.

12. The sleeve assembly of claim 1 wherein the plurality of standoff elements comprises a plurality of standoff ribs lying parallel to a longitudinal axis of the cavity and extending within the cavity of the body a majority of the length of the body.

13. The sleeve assembly of claim 12 wherein each of the first plurality of stops extends between a respective pair of standoff ribs.

14. The sleeve assembly of claim 1, comprising a plate having a plurality of tabs, each tab positioned to bear against the bearing surface of a respective one of the first plurality of stops when the plate is positioned in the cavity with a surface lying in the first plane.

15. The sleeve assembly of claim 14 wherein the plate includes an aperture sized and positioned to provide lateral support to a post that is smaller than the selected size, extending axially within the cavity and traversing the aperture.

16. The sleeve assembly of claim 14 wherein the plate includes a socket sized and positioned to receive a bottom end of a post that is smaller than the selected size, extending axially within the cavity.

17. The sleeve assembly of claim 1, comprising a second plurality of stops extending inward from the inner walls of the cavity without extending into the inner space, each having a bearing surface lying substantially in a second plane, the second plane lying parallel to and separated a selected distance from the first plane.

18. The sleeve assembly of claim 17, comprising a plate having a plurality of tabs each positioned to bear against the bearing surface of a respective one of the second plurality of stops when the stop plate is positioned in the cavity with a surface lying in the second plane.

19. The sleeve assembly of claim 17 wherein the selected distance is four inches.

20. The sleeve assembly of claim 1, comprising a rim extending around the upper aperture at a top end of the body and including an enlarged portion of the body, laterally.

21. The sleeve assembly of claim 20 wherein the rim includes decorative features formed thereon.

22. The sleeve assembly of claim 20 wherein the rim includes a legend identifying a manufacturer of the body.

23. The sleeve assembly of claim 1, comprising a collar including a portion sized to fit within the upper aperture.

24. The sleeve assembly of claim 23 wherein the collar includes a collar aperture sized to receive a post of the selected size, extending axially within the cavity.

25. The sleeve assembly of claim 23 wherein the collar includes a collar aperture sized to receive a post that is smaller than the selected size, extending axially within the cavity.

26. The sleeve assembly of claim 23 wherein the collar includes a plurality of spacing ribs extending between a lower surface of the collar and an upper surface of the body, the spacing ribs being sized to hold the collar a first selected distance above the body, and being spaced apart and having a second selected space between adjacent pairs of the spacing ribs.

27. The sleeve assembly of claim 1, comprising:

an identifier affixed to the body and uniquely differentiating the post sleeve from other post sleeves.

28. The post sleeve of claim 27 wherein the identifier is provided on a plate affixed to the body.

29. The post sleeve of claim 27 wherein the identifier comprises a serial number.

30. The post sleeve of claim 27 wherein the identifier is formed in the material of the body.

31. The post sleeve of claim 27 wherein the identifier is in a machine-readable form.

32. The post sleeve of claim 31 wherein the identifier comprises a bar code.

33. The post sleeve of claim 31 wherein the identifier comprises a radio-frequency identification tag.
