Abstract

Abstract A post assembly and method of capping a post, especially useful for pilings, e.g., as used for docks and the like. A covering over a post end is comprised of a semi-rigid, energy-absorptive, predominantly closed-cell body of foamed synthetic resin with a smooth continuous covering adhered thereto. In a preferred embodiment the covering is a thermoformed cap of predetermined size and shape, cushioned and adhered to the post by the foamed resin, and resistant to abrasion, impact, and ultraviolet deterioration. The foamed resin fills and seals all voids in the end of the post to prevent moisture from entering and deteriorating the post, and cushions and supports the cap to inhibit cracking or puncturing of the cap from impacts in use. The shape of the cap may be selected to provide a convex contour, as for pilings in coastal areas to prevent roosting of birds, and may bear indicia or be of various colors.

Claim 1
Independent Claim 58 words
A post assembly comprising: a post with a solid or closed end, a cover extending across said end and about side portions of the post adjacent said end, said cover being spaced from said end, and a foamed, semi-rigid, energy-absorptive, adhesive completely filling the space between said cover and said end and adhering the cover to the post.
Claim 2
Dependent Claim 58 words
A post assembly comprising: a post with a solid or closed end, a cover extending across said end and about side portions of the post adjacent said end, said cover being spaced from said end, and a foamed, semi-rigid, energy-absorptive, adhesive completely filling the space between said cover and said end and adhering the cover to the post.
Claim 3
Dependent Claim 34 words
A post assembly as set forth in claim 1 wherein said cover is spaced from side portions of the post and said adhesive extends into the space between the cover and said side portions.
Claim 4
Dependent Claim 49 words
A post assembly as set forth in claim 2 wherein said cover is pre-formed to a predetermined size and shape, said space between the cover and said end and side portions being established by the predetermined size and shape, and the foamed adhesive being partially compressed within said space.
Claim 5
Dependent Claim 22 words
A post assembly as set forth in claim 3 wherein said shape includes a convex surface across the end of the post.
Claim 6
Dependent Claim 31 words
A post assembly as set forth in claim 2 including means secured between the cover and post end, in part extending through the cover, for securing an attachment to the cover.
Claim 7
Dependent Claim 63 words
A post assembly comprising: a post with a solid or closed end, and a covering over said end, said covering comprising: a semi-rigid, energy-absorptive, predominantly closed-cell, body of foamed synthetic resin covering said end and side portions of the post adjacent said end, said body having an essentially smooth outer skin, and a smooth continuous covering of synthetic resin adhered to said skin.
Claim 8
Dependent Claim 63 words
A post assembly comprising: a post with a solid or closed end, and a covering over said end, said covering comprising: a semi-rigid, energy-absorptive, predominantly closed-cell, body of foamed synthetic resin covering said end and side portions of the post adjacent said end, said body having an essentially smooth outer skin, and a smooth continuous covering of synthetic resin adhered to said skin.
Claim 9
Dependent Claim 15 words
A post assembly as set forth in claim 6 wherein said covering is a coating.
Claim 10
Dependent Claim 23 words
A post assembly as set forth in claim 6 wherein said covering is a thin flexible film in the form of a bag.
Claim 11
Dependent Claim 84 words
In a method of protecting a pole end, the steps comprising: providing a cap larger than the end to be protected, placing the cap over the pole end with inside surface portions of the cap spaced from the pole end, foaming and expanding a synthetic resin within the space between the cap and pole end, restraining the cap against movement from the pole end as a resin foams and expands, and allowing the resin to harden with the cap spaced from the pole end.
Claim 12
Dependent Claim 84 words
In a method of protecting a pole end, the steps comprising: providing a cap larger than the end to be protected, placing the cap over the pole end with inside surface portions of the cap spaced from the pole end, foaming and expanding a synthetic resin within the space between the cap and pole end, restraining the cap against movement from the pole end as a resin foams and expands, and allowing the resin to harden with the cap spaced from the pole end.
Claim 13
Dependent Claim 28 words
In a method as set forth in claim 9, the additional step of blocking egress of expanding resin from beneath the cap as the resin foams and expands.
Claim 14
Dependent Claim 28 words
In a method as set forth in claim 10, wherein the cap is externally supported in a position spaced from the pole end during foaming of the resin.
Claim 15
Dependent Claim 21 words
In a method as set forth in claim 9, the step of removing the cap after the resin has stopped expanding.
Claim 16
Dependent Claim 21 words
In a method as set forth in claim 9, the step of adhering the cap to the pole with the resin.
