The invention relates to fence posts, and more particularly to bases for fence posts.
As known, wood post or poles are typically employed for forming fences such as wood fences, wire fences, or chain-linked fences. Wood posts are also employed for alternate purposes such as for displaying signage, hanging utility lines or wires, or for general construction purposes. Wood posts typically degrade, rot, wear, or otherwise breakdown or fail structurally faster than other types of posts. The degradation is a result of weather, sun, moisture, exploitation to other harsh parameters and elements.
Replacing or repairing the posts, particularly for residential and lightweight commercial applications, can be time consuming, laborious, expensive, and/or ergonomically undesired. Typically, the post must be dug up to remove the post which is laborious and may also result in damage to landscaping. In order to prolong the lifespan of the posts, other types of posts or solutions may be employed. However, the solutions may be expensive, may not maintain an aesthetic or authentic appeal, may be more complex, or may be less sturdy or durable.
Therefore, it is desirable to provide a structurally stable post assembly including a base portion and a wooden portion, wherein the base portion prolongs longevity, is eco-friendly, maintains aesthetic appeal, minimizes costs, and is easily coupled to the wooden portion.

The post assembly 10 includes an upper first portion 12 and a second portion or base 14 coupled to the first portion 12. The first portion 12 is formed from a wood material or wood composition. The wood material is a treated wood material, wherein the wood is treated with preservative chemicals or compositions. For example, the wood material is 0.40 alkaline copper quaternary (ACQ) wood material that is not kiln dried after a treatment thereof. However, it is understood the upper first portion 12 can be formed from other materials without departing of the scope of the present disclosure. In the embodiment illustrated the first portion 12 is elongate and has a plurality of sides 16, such as four, for example, forming a rectangular cross-sectional shape. However, it is understood the first portion 12 can have any number of sides forming other cross-sectional shapes such as triangular, hexagonal, any other polygonal shape as desired. Additionally, the sides 16 can form a L-shaped cross-sectional shaped, a V-shaped cross-section shape, a T-shaped cross-sectional shape, or any other angled cross-sectional shape. In another example, the first portion 12 can have one continuous side forming a circular, ovular, or other curvilinear shapes. The first potion 12 has a substantially constant width and length along a height of the first portion 12. However, the width and length can vary along a height of the first portion 12 if desired. Where the first portion 12 has a curvilinear cross-sectional shape, the diameter or radius thereof can be constant or vary along a height of the first portion 12.
In the embodiment illustrated, the post assembly 10 is configured to receive a plurality of cross-members (not shown) to form a section of a fence. The first portion 12 includes a plurality of slots 18 for receiving the cross-members. While not illustrated, the first portion 12 can include other features depending on the shape or type of the post assembly 10 being employed. For example, the first portion 12 can include brackets, slots, holes, frames, couplers, etc. for supporting other objects or structure, as desired.
The first portion 12 includes an upper first end 20 opposing a lower second end 22. The first end 20 has chamfered edges 24. Although, the edges can be filleted if desired. The second end 22 is coupled to the base 14 by a coupling device 26 which will be describe din more detail hereinbelow.
The base 14 includes a receptacle 28 for containing a filler 30. The receptacle 28 is hollow and is formed from a heavy duty, non-deteriorating, and ultraviolet (UV) ray resistant plastic material. For example, the material the base 14 is formed from is a thermoplastic polymer or plastic material such as a high-density polyethylene (HDPE) plastic resin, for example. In another example, the base 14 is formed from a polycarbonate (PC) plastic, other types of polyethylene (PE) materials, a polyethylene terephthalate (PET) plastic, polyvinyl chloride (PVC), any other plastic material, or combinations thereof. In yet another example, the receptacle 28 can be formed from a metal that is minimally susceptible to rusting such as aluminium, brass, galvanized steel, or any other durable metal as desired.
In the embodiment illustrated, the base 14 is elongate and has a plurality of sides 32, such as four, for example, forming a substantially rectangular cross-sectional shape. However, it is understood the base 14 can have any number of sides forming other cross-sectional shapes such as triangular, hexagonal, any other polygonal shape as desired. Additionally, the sides 32 can form a L-shaped cross-sectional shape, a V-shaped cross-section shape, a T-shaped cross-sectional shape, or any other angled cross-sectional shape. In another example, the first portion 12 can have one continuous side forming a circular, ovular, or other curvilinear shapes. The base 14 has a length and width substantially equal to a length and width of the first portion 12. For example, the first portion 12 and the base 14 may have a width substantially equal to 5.5 inches and a length substantially equal to 2.5 inches or a width equal to 4 inches and a length equal to 4 inches. As a result, the outer dimensions or perimeter of the base 14 is equal to the outer dimensions or perimeter for the first portion 12. However, the base 14 and the first portion 12 can have any width and length as desired equal to each other or unequal from each other.
The height of the first portion 12 can be any height as desired configured to support the cross-members of the fence or the objects the post assembly 10 is configured to support. For example, for a split-fence assembly, the first portion may have a height of 54 inches to receive three cross-members. The height of the base 14 is configured to provide sufficient support for the first portion 12 and cross-members or the object being supported by the post assembly 10. For example, when the height of the first portion 12 is 54 inches, the height of the base 14 is 30 inches. However, any other heights of the first portion 12 and the base 14 can be contemplated without departing from the scope of the disclosure.
The receptacle 28 can be a black or grey color or a color to match the first portion 12 of the post assembly 10. However, the receptacle 28 can be any color as desired. Additionally, the receptacle 28 can include indicia 34 disposed or formed on an outer surface thereof. The indicia 34 can be a visual marking, such as a line marking, with numerals or letters to indicate a depth in which the base 14 is to be positioned below a stabilizing surface 36 which will be further described hereinbelow. For example, the indicia 34 may be positioned a distance from an upper end of the receptacle 28 adjacent the first portion 12 such as 1 inch from the upper end of the receptacle 28.
The receptacle 28 is divided into a pair of compartments 38 by a dividing wall 40 extending along the height of the receptacle 28 and between opposing sides of the receptacle 28. The wall 40 is configured to increase a rigidity and strength of the receptacle 28. The receptacle 28 is formed from a unitary integrally formed unit. However, the receptacle 28 can be formed from multiple separately formed units that are coupled together to form the receptacle 28.
According to one embodiment of the disclosure, the filler 30 is formed from a rigid material such as a rigid spray foam material. For example, the filler 30 can be a two-component polyurethane spray foam or other liquid plastic spray foam. The filler 30 has a minimum compression strength of 217 kilopascal (kPa) or 31.5 pounds per square inch (psi). According to another embodiment of the disclosure, the filler 30 is formed from a concrete material. The filler 30 is received in bother compartments 38.
The coupling device 26 is a plurality of elongate inserts 42. As illustrated the inserts 42 are elongate cylindrical inserts formed from a steel material such as reinforcing bars. A first portion of the inserts 42 are received by the base 14 and extend at a distance from the upper end of the receptacle 28. The inserts 42 are secured n and embedded in the receptacle 28 by the filler 30, wherein a movement of the inserts is militated against. A second portion of the inserts 42 are received in bores 44 formed in the upper portion 12. The inserts 42 may be maintained within the upper portion 12 by an interference fit, for example. The inserts 42 can include a plurality of ribs formed thereon to facilitate securement with the filler 30 of the base 14 and with the upper portion 12.
In the embodiment illustrated, three of the inserts 42 are employed to couple the base 14 to the upper portion 12. However, more than three or fewer than three of the inserts 42 can be employed as desired. The inserts 42 are staggered with respect to each other, wherein at least a portion of the inserts 42 do no align with each other with respect to the width of the base 14 or the length of the base 14. However, the inserts 42 can align with each other with respect to the width of the base 14 or the length of the base 14. The staggering of the inserts 42 facilitates stabilization of the first portion 12 and militates against racking of the first portion 12. The inserts 42 are positioned substantially parallel to each other in a height direction of the base 14.
A seal 46 such as a capillary gasket, for example, is disposed between the first portion 12 and the base 14. As a result, leaking is prevented from transferring between the first portion 12 and the base 14. Moisture can be prevented from transferring between the portions 12, 14.
The base 14 is configured for positioning beneath the stabilizing surface 36. The stabilizing surface 36 may be a ground for example such as soil or dirt or other surface for placing the post assembly 10 or positioning fences. A majority of the base 14 is positioned beneath the stabilizing surface 36 in a hole formed to receive the base 14 which is backfilled after the hole receives the base 14. A small portion of the base 14 is exposed outside of the stabilizing surface 36. The entirety of the first portion 12 is exposed outside of the stabilizing surface. As a result, when repairing the post assembly 10, only the first portion 12 is required to be replaced. The small portion of the base 14 exposed outside of the surface 36 assists a person in visually identifying the base 14 for replacement of the first portion 12.
To assemble the post assembly 10, compartments 38 of the receptacle 28 are filled with the filler 30. The first portion of the inserts 42 are positioned within the receptacle 28 within the filler 30. It is understood, the inserts 42 can be positioned within the receptacle 28 before or after the filling of the filler 30 depending on the type of material being used as the filler 30. The hole is formed or dug in the stabilizing surface 36, such as in a ground, dirt, or soil, to receive the base 14. The base 14 is positioned in the hole so that the small portion of base 14 extends beyond the surface 36. The indicia 34 is employed by the person to assist in forming the hole with the depth indicated by the indicia. Once the base 14 is positioned in the hole, the hole is backfilled to cover the majority of and stabilize the base 14. The base 14 can then remain beneath the surface 36 without having to remove the base 14 for future maintenance.
The bores 44 are formed in the second end 22 of the first portion 14 to receive the second portion of the inserts 42. The number of and positioning of the bores 44 correspond to the number of and positioning of the inserts 42. The seal 46 is positioned between the first portion 12 and the base 14. When the first portion 12 requires replacement or repairs, the first portion 12 is decoupled from the base 14 and can be replaced with a new one of the first portion 12 or a refurbished one of the first portion.
Advantageously, a portion of the post assembly 10 can be replaced without having to dig up or otherwise open up the hole to remove the base 14. Because the base 14 is formed from a durable material, the base 14 does not have to be replaced as often as the first portion 12. As a result, destruction of landscaping can be minimized, efficiency is maximized, repairs are ergonomically optimized, and costs are reduced when repairing or replacing portions of the post assemblies. Furthermore, the structural integrity of the post assembly is maintained.
From the foregoing description, one ordinarily skilled in the art can easily ascertain the essential characteristics of this invention and, without departing from the spirit and scope thereof, can make various changes and modifications to the invention to adapt it to various usages and conditions.
