Description

BACKGROUND

The use of decorative post covers and columns has become increasingly popular in the railing industry. The post covers and columns are often used to cover unattractive metal fittings and connectors for cable railing or other types of railings. Traditionally, a wood post, such as a 4″×4″ post, for example, has been used to transfer railing structural and force components to the deck or surface on which the inner post is attached, and a decorative wood, fiberglass, PVC or composite sleeve is placed over the inner wood post.

In keeping with such decorative columns or sleeves being decorative, they often do not provide very much mechanical strength or integrity to the railing systems in which they are employed, often being columns or sleeves made of composite materials or fiberglass. Additionally, cable railings are typically lagged into wood posts internal to the decorative sleeve or column, in a labor intensive process requiring the use of expensive hardware and a structural post abutting the column.

An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

In accordance with the various embodiments described herein there is provided a railing support post with pre-threaded, pre-drilled receivers or inserts, or threaded holes that provides not only structural support to a decorative sleeve that may be placed over it, but by having threaded receivers additionally provides a quick and easy way to connect railing fittings to the railing support post. An exemplary embodiment is shown in FIG. 1. The railing support post 100 includes an elongated member 102 having rows of threaded receivers 104, 106 spaced along the length of the elongated member. In FIG. 1, the elongated member 102 has a first line of threaded receivers 104 in a first face or side of elongated member 102 and a second line 106 in a second face or side of elongated member 102. The other faces of the elongated member may also include threaded receivers. The threaded receivers are configured to receive rail fittings suitable for cable railings, but may be used alone.

The elongated member 102 has sufficient strength to support railings, handrails or other fittings, coupled via the threaded receivers 104, 106, to it. The threaded holes or receivers 104, 106 of the railing support post 100 are spaced in accordance with spacing of railing to be attached to it and so can support industry standard railing. The post height may correspond to an industry standard height, such as 36 inches for residential use and 42 inches for commercial use, for example. Thus, the railing support post 100 may be a 36 inch residential post or a 42 inch commercial post. It will be understood that railing support posts of varying heights may be used without departing from the spirit and scope of the described embodiments. For example, a shorter railing support post could be mounted on a knee wall, while a longer railing support could be mounted with a column or side-mounted on a facia.

The railing support post may be made of metal, such as stainless steel, aluminum, bronze, or other metal material, or composite material such as material with carbon fibers, etc., with pre-threaded holes or receivers, thereby allowing cables or other railings of a railing system to be attached via standard stainless steel or other known hardware and fitting options to this railing support post. The threaded receivers 104, 106 of the railing support post 100 may be evenly spaced threaded holes (such as vertically to meet code) that are used when cable infill is needed or desired.

While the railing support post is illustrated as being substantially rectangular in shape, it is not so limited and may in fact be at least partially round or other shapes. Here, the term “rectangular” is defined to include “square”.

As described below, a separate bracket may be used for the graspable handrail when desired or needed, as for a 42 inch commercial application, for example.

The railing support post may be mounted to a variety of surfaces, such as decking, stairs, flooring, etc. To facilitate mounting, a base 108 may be fixed to the lower end of the elongated member 102. One or more holes 110 in the base may be provided for fasteners.

The railing support post 100 also includes a sleeve support 110 coupled to the elongated member 102, the sleeve support 110 is configured to support a decorative sleeve such that the elongated member is located in the interior of decorative sleeve. The sleeve support 110 may include one or more threaded holes 112 to enable coupling of the post 100 to a decorative sleeve and/or a handrail.

When used for guardrail protection or with hand rails together with hollow composite sleeves, the railing support posts allow for cables to be attached from any direction. Thus, the railing support post may be an end post, a corner post, an intermediate post, etc. The railing support post may then work in concert with other posts of an overall railing system. For example, intermediate posts may be used in long sections of railing or fencing, where cable railing passes straight through the intermediate posts, or may operate independent of other posts. Accordingly, threaded receivers may be located on one or more sides and may be used to receive rail fittings or to allow passage of a cable rail. In one embodiment, threaded receivers are located on four sides of the elongated member.

FIG. 2 is a diagrammatic representation of a decorative sleeve or post cover 200 configured to at least partially enclose a railing support post. The decorative sleeve 200 may be constructed of a light-weight, non-structural material, such as PVC or fiberglass. One or more holes 202 may be provided to allow railing fittings to pass through the sleeve to threaded receivers in the interior railing support post. Additional holes 204 may be provided to enable coupling of the decorative sleeve 200 to a sleeve support of the railing support post.

The decorative sleeve may be provided without holes 202 and 204. The holes may be added, as needed, during installation of a railing assembly. To facilitate installation, a drill-hole template may be provided to indicate where holes may be drilled in the decorative sleeve so as to align with the threaded receivers in the elongated member. The template, support post, decorative sleeve and other components may be provided as a kit.

In an exemplary embodiment, the elongated member has a substantially square cross-section, with outside width approximately 2 inches. In a further embodiment the outside width is in the range 1-3 inches. Larger or smaller widths may be used without departing from the present disclosure.

The elongated member may have a solid, hollow, U-shaped, L-shaped, T-shaped, H-shaped, I-shaped, round, rectangular or other cross-section. The elongated member may be constructed of a thin-walled material, such as ⅛″, 3/16″, ¼″ or 5/16″ metal. Other materials and material thicknesses may be used, provided the railing support post has sufficient strength to support one or more railings.

In an exemplary embodiment, the decorative sleeve has a substantially square cross-section, with outside width approximately 5 inches. In a further embodiment the outside width is in the range 4-6 inches. Larger or smaller widths may be used without departing from the present disclosure.

The decorative sleeve 200 is sized to pass over the elongated member and the base support bracket of the railing support post.

In an exemplary embodiment, the base support bracket of the railing support post is substantially square, with width approximately 4.2 inches. In a further embodiment the outside width is in the range 2-7 inches. Larger or smaller widths may be used without departing from the present disclosure.

FIG. 3 is a diagrammatic representation of a decorative sleeve cap 300 configured to be located on top of a decorative sleeve. In a further embodiment, the decorative cap 300 is integral with the decorative sleeve. A variety of cap styles will be apparent to those of ordinary skill in the art. In some embodiments, the cap is integrated with the decorative sleeve.

FIG. 4 is a vertical, cross-sectional view through an assembly of a railing support post 102, a decorative sleeve 200 and a decorative sleeve cap 300, in accordance with one or more embodiments. Various embodiments of threaded receivers 106 are shown by way of explanation. In practice, a railing support post may contain a single type of threaded receiver. Receiver 106a comprises a front-plate, with both the front-plate and elongated member 102 being threaded. Receiver 106b comprises a simple threaded hole in the elongated member 102. Receiver 106c comprises a threaded insert. Receiver 106d comprises a threaded flow-drilled hole. Receiver 106e comprises a threaded front-plate. Other types of threaded receivers will be apparent to those of ordinary skill in the art.

In the example embodiment shown, the railing support post is coupled to a surface 402 using fasteners 404. Various types of fasteners may be used.

Railing fittings that are configured to be placed in tension may be passed through holes 202 in the decorative support sleeve 200 and screwed into threaded receivers 106 of the railing support post. Fittings that require a mating surface may be coupled via a spacer, such as hollow spacer 406 that rests against the elongated member 102. Spacer 406 provides an external mating surface and is sized to span the gap between the elongated member 102 and the exterior of the decorative sleeve 200, passing through a hole in the decorative sleeve 200. The spacer 406 is adapted to protect the decorative sleeve from compressive loads when a rail fitting is coupled to the threaded receiver of the elongated member. Spacer 406 may also be used, for example, when a cable rail is angled diagonally up or down, as for a step or stair railing to prevent loading of the decorative sleeve.

The decorative sleeve 200 may be attached to the sleeve support 112 of the railing support post via a fastener 408.

Together, the decorative sleeve 200 and support cap 300 enclose the railing support post 300.

The railing support post allows for the tensioning of cables to be transferred to the surface of the railing support post inside a decorative sleeve, thereby allowing the decorative sleeve or shell to become lighter and more decorative.

A top handrail or guard rail may be bolted directly to the railing support post using the threaded holes in the top sleeve support 112. In one example embodiment, the sleeve support 112 comprises square tubing, such as 1 inch square, for example. This will accommodate all angles that a standard stair arrangement might use. The sleeve supports 112 may be attached at one or more positions on the elongated member. The sleeve support may be pre-attached, by welding or bonding for example, or may be attached using fasteners. The sleeve support is sized to accommodate the decorative sleeve to be used.

A grab-rail 410 may be attached to the railing support post via spacer 406 and bracket 412. A threaded fastener 414 passes through the spacer 406 and the threaded portion 416 of the fastener screws into a threaded receiver of the elongated member 102. An additional hollow spacing element 418 may be used to provide a stand-off. Optionally, elements 406 and 418 may be combined as a single spacer that enables the bracket 412 to be coupled to the elongated member 102 without loading the decorative sleeve 200.

In a further embodiment, the sleeve support is integrated with the decorative sleeve. In a still further embodiment, the decorative cap is integrated with the decorative sleeve. In a still further embodiment, the sleeve support, the decorative sleeve and the decorative cap are integrated. For example, the sleeve support, the decorative sleeve and the decorative cap may be molded as a single plastic part.

FIG. 5 is a vertical, cross-sectional view through an assembly of a railing support post 102, a decorative sleeve 200, a decorative sleeve cap 300 and exemplary railing fittings, in accordance with various embodiments. A horizontal guardrail 502 may be coupled to the sleeve support 112. Mechanical loads placed on the guardrail 502 are carried by the elongated member 102 of the railing support post rather than by the decorative sleeve 200. A grab-rail 410 may be coupled to the elongated member by a support bracket 506. In the example shown, the support bracket 506 has a flange that is mounted to the elongated member 102 using two threaded receivers. In one example embodiment, the attachment point of the bracket 506 may be located approximately one fourth of the way between the flange holes and/or may be invertible to allow for a variety of handrail heights. By way of illustration, the grab-rail 410 and support bracket 506 are depicted as being coupled to the right of the elongated member 102. However, the grab-rail 410 and support bracket 506 may be coupled to the front or back face of the elongated member 102 so as to provide a grab-rail 410 running parallel to the cable sections 508.

Cable sections 508 may be attached to the threaded receivers 106 of the railing support post using fittings 510. The fittings 510 have a threaded section 512 that may be screwed in a threaded receiver to hold the cable section 508 in tension. The fittings 510 pass through the decorative sleeve 200 but are not supported by it. Thus, the decorative sleeve 200 may be constructed of various light weight decorative materials.

The fittings 510 may have two threaded ends 512. One threaded end of a fitting may have left-hand thread and the other end a right-hand thread to facilitate tensioning. One threaded end allows coupling to a cable rail while the other threaded end 512 allows coupling to the elongated member 102. Tension in the cable section 508 may be adjusted by rotating the body of the fitting. Rotation may be facilitated by a hexagonal, square, or flattened section of the fitting.

FIG. 6A is a partial, cross-sectional view through an assembly of a railing support post 102, a decorative sleeve 200 and exemplary railing fittings, in accordance with various embodiments. A cable section 508 is passes through a flow-drilled hole 106 in the decorative sleeve or post cover 200 and is coupled to the elongated member 102. Insert 602 may be screwed on the threaded portion 512 of the rail fitting 510 and functions to protect the decorative sleeve 200 surround the fitting and to enhance appearance of the assembled railing. The fitting may be provided with a hexagonal, square, or flattened section 604 to facilitate tensioning of the cable section 508. Other types of fittings will be apparent to those of ordinary skill in the art.

In FIG. 6A, the wall thickness of decorative sleeve or post cover 200 is depicted as being thinner than the wall thickness of the elongated member 102. However, other wall thicknesses may be used without departing from the present disclosure. For example, FIG. 6B is a partial, cross-sectional view through an assembly of a railing support post 102, a decorative sleeve 200 and exemplary railing fittings, in accordance with an embodiment. In this embodiment, the wall thickness of decorative sleeve or post cover 200 is depicted thicker than the wall thickness of the elongated member 102.

FIG. 7 is a cross-sectional view of an assembly of a railing support post 100, a decorative sleeve 200, a decorative sleeve cap 300 and exemplary rail fittings 510, consistent with certain embodiments. The base support bracket 108 is fastened to the surface 402 using fasteners 404. The decorative sleeve 200 is placed over the elongated member 102 of the railing support post 100, and decorative cap 300 is installed. Guard rails 502 are attached to the sleeve support 112 of the railing support post using fasteners 408. In the embodiment shown, the cable rails 508 extend through threaded receivers 106 the elongated member 102 and holes 202 in the decorative sleeve 200 to emerge on the opposite side of the decorative sleeve. In this way, the cable rails 508 can continue through one or more railing support posts to extend the rail. In addition, a variety of rail fittings may be used. The rail fitting may be configured to facilitate screwing the fitting into a threaded receiver to apply tension to the attached cable rail.

In the embodiment illustrated in FIG. 7, the decorative cap 300 is incorporated with the decorative sleeve 200. In addition, the elongated member may be embedded in the decorative cap to provide the sleeve support.

The railing support post may also be used in conjunction with many kinds of lighting fixtures, should the need arise.

A wide variety of materials may be used for each of the various components, fixtures, and elements described herein, including aluminum, stainless steel, steel, wood, cast aluminum, brass, bronze, aluminum bronze, nickel aluminum bronze, nick bronze, carbon fiber, and plastic, as well as cast, extruded or extrusion parts.

FIG. 8 is a view of a railing assembly using two railing support posts, consistent with certain embodiments. The first railing support post 100a is located in a decorative sleeve 200a that take the form of a pillar that extends from floor 402 to ceiling 802. A cable 804 may be stretched between the floor 402 and the ceiling 802 to help support the railing support post 100a and help meet hurricane “lift-off” requirements. A second railing support post 100b is fastened to the floor 402. The railing support post 100b may be fastened using a base support bracket, a cable fastened to the floor, or a combination thereof. The railing support post 100b is covered by a decorative sleeve 200b and a decorative cap 300. A guard rail 502 is coupled to the first railing support post 100a via bracket 506 and to the second railing support post via sleeve support 112. A number of cable rails 508 are stretched between the two railing support posts. The cable rails 508 are coupled to the railing support posts using fittings 510 that screw into threaded receivers of the railing support posts. The fittings 510 enable the tension in the cable rails to be adjusted. The tension is supported by the railing support posts 100a and 100b so that the decorative sleeves 200a and 200b can be constructed of light-weight decorative materials. The height of the guard rail 502 and the spacing between cable rails 508 may be selected to meet building codes. The cable rail spacing may be predetermined, so that the threaded receivers can be fabricated when the support post is manufactured, thereby minimizing the installation time of a railing assembly.

In an exemplary embodiment, the threaded receivers are evenly spaced at approximately 3.09 inch spacing. However, other spacing may be used.

FIG. 9 is a flow chart 900 of a method for manufacturing a rail support post, in accordance with certain embodiments of the disclosure. Following start block 902, an elongated member of a desired length is provided. The desired length may correspond to a standard length specified in a building codes, or may be a custom length. At block 906 a plurality of holes are drilled in the elongated member. The holes are spaced in a row along the length of the elongated member. Rows of holes may be place on some or all sides of the elongated member. The elongated member may have a hollow or solid cross-section. When a hollow or angular cross-section is used, the holes may be drilled using flow-drilling, so as to increase the thickness of the elongated member in the vicinity of the hole and provide an increased thread length. This approach allows thinner materials to be used without the use of front- or back-plates to increase the thread length. However, other methods may be used to create the holes, such as conventional drilling, laser cutting, punching, etc. The holes are tapped at block 908 to form a plurality of threaded receivers. The threaded receivers are configured to receiver rail fittings due use, and may be fabricated by other means.

At block 910, a base support bracket is prepared. In one embodiment, the base support bracket is made by cutting the bracket from a sheet of metal and drilling or cutting holes in it to enable it to be attached to a mounting surface. Optionally, a lower sleeve support may be incorporated. In one embodiment this may be done by machining one or more steps in the block to form one or more raised platforms sized to fit inside a hollow decorative sleeve placed over the post. In a further embodiment, one or more upper plates may be added in a stack to form one or more raised platforms, again sized to fit inside a hollow decorative sleeve placed over the post. The edges or corners of an upper plate may be bent upwards to guide the plate(s) inside the decorative sleeve.

At block 912, a base support bracket is attached to an end of the elongated member, the base support bracket being configured to enable the elongated member to be fastened to a surface when in use. The base support bracket may be attached by welding or bonding, for example.

At block 914, a sleeve support is attached to the elongated member. The sleeve is configured to provide support for a decorative sleeve that, at least partially, encloses the elongated member in use. The sleeve support may be attached by welding or bonding, for example. The manufacture terminates at block 916.

Additional manufacturing steps may be performed. For example, if the support post is constructed of stainless steel, a passivation step may be included. For other materials, an anti-corrosion coating may be applied, for example.

As described above a cable rail support post may be produced by a process comprising: providing an elongated member having one or more walls, flow-drilling a number of holes in at least one walls of the elongated member, the holes spaced along a length of the elongated member. Flow-drilling a hole increases the thickness of the wall in the vicinity of the hole. The flow-drilled holes are tapped to produce multiple threaded receivers spaced along a length of the elongated member, that can be used to receive cable rail fittings. A base support bracket is attached to a lower end portion of the elongated member, the base support bracket configured to enable the cable rail support post to be fastened to a surface. A sleeve support may be joined to the elongated member, at the upper or lower end portion, for example, the sleeve support adapted to support a decorative sleeve that at least partially encloses the elongated member. In one embodiment, the base support bracket is welded to the first end portion of the elongated member.

The base support bracket may be produced by machining the steps in a metal plate or by casting. Machining may be performed by a known process, such as turning, milling, planing, shaping, broaching, grinding, ultrasonic machining, chemical machining, electrical discharge machining, electrochemical machining, high-energy beam machining, etc.

In one embodiment, the height of the steps is approximately 1/16″. In a further embodiment the height of the steps is greater than 1/16″.

FIG. 12 is a diagrammatic representation of cross-section of a lower portion of a cable railing support post assembly, consistent with certain embodiments. The assembly includes the elongated member 102 and the base support bracket 108 that form the cable rail support post. The base support bracket is attached to surface 402 using fixing 404 that passes through a hole 110 in the bracket. In practice, fixings 402 would be placed in two or more of the holes 110. The assembly also includes a hollow decorative sleeve 200 that passes over the elongated member 102 and rests on a step 1104 of the base support bracket 108. In the example shown, the sleeve rests on the lower step. Sleeves with smaller internal dimension 1204 might rest on a different step. A decorative collar 1206 may be placed around the base of the support post and sleeve to hide the edges of the base support bracket 108 and the lower end of the sleeve 200. In this example, hole 1208 is aligned with hole 1002 to provide drainage. In this example, the raised platforms are integral to (part of) the base support bracket and provided a lower support for the decorative sleeve 200.

FIG. 13 is a diagrammatic representation of a lower portion of a cable railing support assembly viewed from above, consistent with certain embodiments. In this embodiment, the base support 108 includes a lower plate 1302 that is attached to the elongated member 102, and an upper plate 1304 that provides a lower support for the decorative sleeve. The lower plate 1302 has sufficient strength to provide structural support for the post. In one embodiment, the plate is approximately ⅜″ thick. In further embodiments, the plate thickness is as little as ¼″, but may be thicker, such as approximately ½″, ¾″ or 1″. The thickness may be selected according to the material of the base support bracket and/or the height of the post.

The upper plate 1304 may have a central cut-out 1308 with sufficient width 1306 to enable it to be positioned before or after the elongated member 102 is joined to the base support bracket 108. The upper plate 1304 also has a number of holes 1301 that align with corresponding holes in the lower plate 1302. The dimension 1006 of the upper plate is selected to mate with an internal dimension of a decorative sleeve. Thus, in use, the upper plate prevents lateral motion of the decorative sleeve. The upper plate may be joined to the lower plate during manufacture, or may be supplied separately and held in place by the base support bracket fixings. More than one upper plate may be stacked to allow for decorative sleeves of different internal dimensions.

FIG. 14 is a view of the section 14-14 shown in FIG. 13. This view illustrates how the combination of the lower plate 1302 and the upper plate 1304 form a step 1004 and a raised platform 1304. Hole 1002 is open to the interior of the elongated member 102 to provide drainage.

FIG. 15 is a diagrammatic representation of a further upper plate of a base support bracket of a cable railing support post viewed from above, consistent with certain embodiments. In this embodiment, the upper plate 1304 is cut from a sheet of metal. Holes 1310 and central cut-out 1308 may be cut during the same process step. The corners 1502 of the plate are bent upwards to positions 1502′ at approximately 90° to the plate. The cutting and bending may be performed in a single stamping process or as separate processes. In one embodiment, perforations are cut along the bend lines to facilitate bending during manufacture or bending at a later time, such as the time of installation.

FIG. 16 is a side view of the upper plate shown in FIG. 15. This view shows the corner 1502′ at approximately 90° to the lower portion of the plate. The corners function as guides for a decorative sleeve as it is passed over the support post and prevent lateral motion of the decorative sleeve once it is positioned.

FIG. 17 is a diagrammatic representation of a lower portion of a cable railing support post assembly, consistent with certain embodiments. As described above, the corners 1502′ function as guides for a decorative sleeve 200 as it is passed over the support post 102 and prevent lateral motion of the decorative sleeve 200 once it is positioned. The material of the upper plate 1304 may be selected to allow for manual flexing of the corners 1304 to accommodate manufacturing variability in the decorative sleeves. Fixings 404 pass through aligned holes 1310 in the upper plate and 110 in the lower plate and server to support the post and join the upper plate 1304 to the lower plate of base 108.
