The present invention relates to decorative columns, and more particularly relates to decorative columns made from polyvinyl chloride (PVC).
For centuries, column structures have been constructed from wood and/or stone since each is a readily available and workable material. More recently, column structures made from other materials such as polyvinyl chloride (PVC). The use of materials such as polyvinyl chloride (PVC) permits the addressing of various problems with prior art column structures, such as versatility, cost-effectiveness, preventing uplift of the column structure during a strong wind, physical and aesthetic degradation due to weather, rotting, acceptable manufacturing costs, acceptable maintenance costs, ready manufacturability, warpage and dimensional changes caused by moisture absorption, undesirably high weight, cost effectiveness, aesthetic appeal, aesthetic versatility, among other features.
One known relevant prior art column assembly can be found in U.S. Pat. No. 7,275,349 issued Oct. 2, 2007, to Auman, and entitled Split Column Reassembly System. This split column reassembly system allows a split column, capitol or base to return to its intended position during its installation around a load bearing structural device. It is done through forming the pieces of the seams in order that they fit back together accurately after separation and during installation. The system comprises at least a first structural portion and a second structural portion that together define an interface. First and second keyed surfaces permit intermeshing the first structural portion with the second structural portion in a unique arrangement such that the first and second structural portions are retained in a desired orientation with respect to one another. A separator sheet is configured to be temporarily interposed between the first and second structural portions during intermeshing of the first structural portion with the second structural portion.
Another known relevant prior art column assembly can be found in United States Published Patent Application No. 2001/0022056 published Sep. 20, 2001, to Gifford, and entitled Decorative Post Cover. This decorative post covering has two L-shaped members that are sized and shaped to fit around a post. The decorative post cover includes an attachment mechanism for attaching the first and second members together and around the post. The attachment mechanism is formed integral to the L-shaped members. The attachment mechanism includes a lip end and a receiving end on each of the first and second members. The lip end of the first member is connected to the receiving end of the second member and the lip end of the second member is connected to the receiving end of the first member. The first and second members are identical and therefore interchangeable. The first and second members have longitudinal scalloped grooves molded therein to increase the rigidity of members and give the appearance of a pillar or column.
Another known relevant prior art column assembly can be found in U.S. Pat. No. 7,621,080 issues Nov. 24, 2009, to Stanfield, and entitled Protective Sleeve Assembly For A Post. In this assembly, a post has a rectangular cross-sectional shape and is mounted on one end of the post is a protective sleeve. The sleeve provides a cylindrical sidewall within which one end of the post is engaged. A bottom cap closes the end of the sidewall sealing the end of the post. A rectangular elastomeric seal is engaged with the sidewall peripheral to the post. A pair of L-shaped moldings are mounted exterior to the elastomeric seal providing engagement within a groove of the elastomeric seal and exerting a sealing force against the elastomeric seal and the post.

In accordance with one aspect of the present invention there is disclosed a novel decorative column for use in surrounding a vertical structural column. The decorative column comprises a plurality of interlocking panels, with each of the panels comprises a main body having an interior face, an exterior face, a first side edge and a second side edge. The first side edge comprises a first notch extending along the length of the first side edge and defined by an exterior flange and an interior flange. The exterior flange terminates in a first slanted outer edge surface that is oriented at a first acute angle with respect to the exterior face of the main body. The second side edge terminates in a second slanted outer edge surface extending along the length and that is oriented at a second acute angle with respect to the exterior face of the main body, and with the second slanted outer edge surface leading to a transverse flange extending along the length of the second side edge and projecting towards the interior face of the main body, with a second notch disposed adjacent the transverse flange extending along the length of the main body. The first acute angle and the second acute angle sum to ninety degrees (90°). The transverse flange of one interlocking panel engages the first notch of another interlocking panel. The interior flange of one interlocking panel engages the second notch of another interlocking panel.
In accordance with another aspect of the present invention there is disclosed a novel squaring apparatus for use in installing a decorative column surrounding a vertical structural column. The squaring apparatus comprises a first squaring member and a second squaring member. Each squaring member comprises a first leg having a first outer abutment surface and a first inner abutment surface, and a second leg having a second outer abutment surface and a second inner abutment surface. The first outer abutment surface and the second outer abutment surface are oriented at ninety degrees (90°) to each other. The first inner abutment surface and the second inner abutment surface are oriented at ninety degrees (90°) to each other. The first outer abutment surface and the second outer abutment surface are decoratively formed.
In accordance with another aspect of the present invention there is disclosed a novel co-operating pair of panels for forming a decorative column for use in surrounding a vertical structural column. The co-operating pair of panels comprise a first panel and a second panel, wherein each of the panels comprises a main body having an interior face, an exterior face, a free side edge and a joined side edge. The joined side edge of the first panel is oriented at a first acute angle with respect to the exterior face of the main body, and the joined side edge of the second panel is oriented at a second acute angle with respect to the exterior face of the main body. The joined side edge of the first panel has a notch therein and the joined side edge of the second panel has a co-operating protrusion therein. In use, when the first panel and a second panel are folded together in an installed in-use configuration, the protrusion is received in the notch to thereby preclude movement of the two vertical panel members one with respect to the other.
The novel features which are believed to be characteristic of the decorative column according to the present invention, as to its structure, organization, use and method of operation, together with further objectives and advantages thereof, will be better understood from the following drawings in which a presently known embodiment of the invention will now be illustrated by way of example. It is expressly understood, however, that the drawings are for the purpose of illustration and description only, and are not intended as a definition of the limits of the invention. In the accompanying drawings:

As can be readily seen in
In the first illustrated embodiment, the first notch 160, the exterior flange 162, the interior flange 164, and the first slanted outer edge surface 163 extend along the entire length of the first side edge 156. Further, the second slanted outer edge surface 165, the transverse flange 166, and the second notch 168, extend along the entire length of the second side edge 158. Also, the first acute angle and the second acute angle may be each about forty-five degrees (45°). For the sake of robustness, the thicknesses of the exterior flange 162, the interior flange 164, and the transverse flange 166 are approximately the same one as the others.
As described, a strong connection is provided to resist breaking and also resist angular movement.
Reference will now be made to
In one aspect of the second illustrated embodiment column structure 200, the first vertical panel member 210, the second vertical panel member 220, the third vertical panel member 230 and the fourth vertical panel member 240 may be considered to be co-operating pair of panels for forming a decorative column for use in surrounding a vertical structural column. The co-operating pair of panels may comprise the first panel 210 and the second panel 220, or may comprise the third panel 230 and the second panel 240. Reference will be made to the first panel 210 and the second panel 220 for the sake of ease of reference.
The first panel 210 comprises a main body 211 having an interior face 212, an exterior face 213, a free side edge 214 and a joined side edge 215. The second panel 220 comprises a main body 221 having an interior face 222, an exterior face 223, a free side edge 224 and a joined side edge 225. The joined side edge 215 of the first panel 210 is oriented at a first acute angle with respect to the exterior face 213 of the main body 211. The joined side edge 215 of the second panel is oriented at a second acute angle with respect to the exterior face 223 of the main body 221. The first acute angle and the second acute angle may sum to ninety degrees (90°). The joined side edge 215 of the first panel 210 has a notch 215n therein and the joined side edge 225 of the second panel 220 has a co-operating protrusion 215p therein. More specifically, at each of the vertex type joints, the joined side edge 215 has a “V”-shaped notch 215n (“V”-shaped in cross-section) therein and the joined side edge 225 has a cooperating “V”-shaped protrusion 215p thereon (“V”-shaped in cross-section). The shape of the “V”-shaped notch 215n and the “V”-shaped protrusion 215p are substantially mirror images one of the other.
In use, when the first panel 210 and a second panel 220 are folded together in an installed in-use configuration, the protrusion 215p is received in the notch 215n to thereby preclude movement of the two vertical panel members 210,220 one with respect to the other.
Once the two vertical panel members have been folded together, the positioning of the “V”-shaped protrusion 252p in the “V”-shaped notch 215v precludes movement of the two vertical panel members one with respect to the other, thus helping to preclude cracking of the small amount of PVC material at the vertex type joint.
Reference will now be made to
The squaring apparatus 300 may be used between the panels of the column structure and the vertical structural column that the panels surround, or may be used on the exterior of the panels of the column structure.
After the vertical panel members of the column structure are put in place at the bottom of the column structure, the first squaring member 301 and the second squaring member 302 of the squaring “L” 300 are secured in place using threaded fasteners (not specifically shown) extending through cooperating apertures 304 so as to engage the receiving surface 306.
