Description

TECHNICAL FIELD

The present disclosure relates to systems and methods for attaching hollow posts, such as vinyl posts for railings, to decking.

BACKGROUND

There are a number of known systems for securing posts that support a fence or a railing. For example, U.S. Pat. No. 8,117,798, the disclosure of which is incorporated by reference herein, discloses an apparatus with a base that can be attached to a surface and a tubular member that extends upward from the base, which is used to pierce a solid post. U.S. Pat. RE 36550, a reissue of U.S. Pat. No. 5,404,682, the contents of each of which are incorporated by reference herein in their entireties, discloses an adjustable mounting for a hollow post that uses a ball segment and seat to provide adjustability to a hollow post when attached to an unleveled anchor.

Turning to FIG. 1, a mounting system currently used and sold by the applicant is depicted. An anchor member 100 is formed as a body having an external lip that is held in a channel formed in the sidewall of a hollow post P. A bolt 104 that is secured to an anchor 108 in concrete 110 passes through a central hole in the anchor member 100. A large metal plate or washer 102 is disposed on the anchor member 100 and a nut 106 is used on the bolt 104 to secure the anchor 100 thereon. It has been found that the washer 102 is necessary to prevent the nut 104 from damaging the anchor due to the force required to properly secure the post. Otherwise the anchor may be caused to “cave in” or otherwise fail. In addition to a concrete anchor 108, this system has been used with bolts set directly in concrete or lag bolts that pass through decking material.

FIG. 2, depicts a fixture 20, that is used to allow the anchor of FIG. 1 attach to a decking surface. A flat metal base 200 includes several screw holes 202 that allow attachment to decking or another flat surface. A threaded rod 204 is welded to a middle portion of the base 200 and rises directly therefrom. As depicted, the large metal washer 102 is sized and configured to be retained on the rod 204 when a post P is attached thereon as depicted in FIG. 1. While the system of FIG. 1 when used with the fixture of FIG. 2, has been successful in operation, it requires additional steps to install leading to increased labor costs, and the use of the custom fixture 200, which can increase materials cost per post. A system or method that allowed for a hidden and secure attachment of posts to a decking surface without these additional expenses would be an improvement in the art. Such a method or system that could be used for multiple different attachment methods would be a further improvement in the art.

SUMMARY

The present disclosure includes apparatus, systems, and methods for securing anchoring posts to a decking surface without the use of a metal plate or washer to redirect force from a single central fastener on an internally mounted anchor, or the use of an externally visible connector. An anchor member having a generally planar lower surface and vertical sidewalls has connection ridges extending out from those sidewalls that correspond to channels formed in the internal sidewalls of a hollow post member. A taper is formed at the bottom end of the post to allow the anchor member to slip past the end of the post, which would normally be a blunt end preventing the anchor member from being inserted. Using a press, the anchor member is pressed past the taper and into a secured position in the post. A plurality of attachment holes are disposed in a pattern around the anchor member, passing from the planar lower surface through the body thereof. For installation, a post with the fitted anchor is placed in the desired position on a decking surface and a plurality of lag screws or other fastening devices are attached to the decking surface to secure the anchor member and post thereto. The use of multiple screws at multiple locations on the anchor member reduces the force at any single location, reducing the chance for installation failure while achieving secure attachment of the post.

DETAILED DESCRIPTION

The present disclosure relates to systems and methods for securing hollow posts, such as posts P shown in FIG. 5, for a railing attached to a decking surface 340, such as a deck made of wood or a composite material or on a set of stairs. It will be appreciated by those skilled in the art that the embodiments herein described, while illustrating certain embodiments, are not intended to so limit the disclosure or the scope of the invention. Those skilled in the art will also understand that various combinations or modifications of the embodiments presented herein can be made without departing from the scope of this disclosure. All such alternate embodiments are within the scope of the present invention.

Referring to FIGS. 3A, 3B, 3C, and 5, a first embodiment of an anchor member 30 is depicted. As depicted, anchor member 30 may be formed as a body 300 having a generally planar lower surface 302 with a surrounding sidewall 310. In the depicted embodiment, the sidewall 310 may include a lower ridge that extends past the upper surface. At an upper surface, the body 300 may be open with a series of reinforcing walls 330 surrounding voids 320 to reduce weight and material usage, although it will be appreciated that solid embodiments may be contemplated.

In the depicted embodiment, the body 300 has an octagonal shape with four longer sides that generally define a square with respect to one another, and four smaller sides that “cut off” the corners of the square. These smaller sides may also be radiused. The depicted embodiment is intended for use with a generally square hollow post, but it will be appreciated that other shapes may be used, for example, with non-square rectangular posts, ovoid posts, or rounded posts. The shape of the body may be varied to accommodate such posts.

Along each of the four longer sides, a ridge 312 extends laterally from the sidewall 310. As depicted, each ridge 312 may be formed as a shelf having a thickness with generally planar upper and lower surfaces. Further, each ridge 312 may taper outwardly, or bow, in a generally horizontal direction, such that the ridge 312 is convex and has a farthest extending lateral point 317 at a region near the midpoint of the side of the ridge 312 on which said farthest extending lateral point 317 is located, with a gradual taper to a corner 313, where the ridge 312 then shares a common angle with the shorter side 319. The generally horizontal taper 317 is shown more clearly in FIG. 3D. In practice, this has been found to facilitate placement in hollow vinyl posts, such as hollow post P as shown in FIG. 5 as the sidewalls of the post P will flex outward as the anchor member 30 is pressed into place, with the stiffer corners of the post P resisting such flexing. Upon installation, the ridges 312 will reside in corresponding channels 321 in the internal sidewall of the post, as discussed further herein. It will be appreciated that alternate embodiments of hollow posts with square corners are possible and may be useful for some particular installations.

Along each sidewall 310, vertically disposed insertion ridges 315 may extend from the top surface of the ridge 312 to the upper end of the anchor 30. Each insertion ridge 315 may be formed as a columnar protrusion having a thickness that is smaller than that of the ridge 312. In other embodiments, it may be angled from a smaller thickness near the ridge 312 to a thinner portion near the upper end. Although depicted as having a partially elliptical cross-section, it will be appreciated that each insertion ridge 315 may be a rectangular or other shape. An alternate method would be to extend the wall to the same distance from the center of the anchor as the outermost point on the ridges are from the center of the anchor. These ridges 315 are formed to aid in the insertion of the anchor 30 by pre-spreading the wall of the post P to allow the broader ridge 312 to slip past the taper 331 formed at the bottom end of the post P. The ridges 315 are formed such that they operate to prespread the post P at the open end of the post P as shown in FIG. 5, such that the taper 331 allows the anchor 30—specifically, the ridge 312 on the anchor 30—to slip past the taper 331 and avoid bottoming out on a blunt end of the post P at the open end of the post P as shown.

A larger central attachment hole 304 is disposed in the center of the anchor member 30, passing from the lower surface 302 through the body 300. As depicted, the center hole may have a surrounding reinforcing wall and is sized for the insertion of a larger diameter bolt there through for a single point of fastening the post and anchor to a surface. This allows for use of the anchor member with the type of securing using a larger sized plate or washer as discussed above in connection with FIG. 1.

A number of smaller diameter decking attachment holes 306A, 306B, 306C, and 306D are disposed in the anchor member 30, spaced out from the center and from one another around the lower surface 302 and at points closer to the edges thereof. Each decking attachment hole passes from the lower surface 302 though the body 300. As depicted, each may have a surrounding reinforcing wall. Each decking attachment hole is sized for the insertion of a screw therethrough for attachment to decking as discussed further herein.

In the embodiment depicted in FIGS. 3A and 3B, there are four decking attachment holes 306A, 306B, 306C, and 306D, each disposed at a location near a corner of the body 300 of the anchor member 30. It will be appreciated that the particular placement and number of decking attachment holes may vary. For example, anchor member 40A, depicted in FIG. 4A has four additional decking attachment holes 306E, 306F, 306G, and 306H each disposed through the body with an opening on the lower surface in line with a midpoint of each longer sidewall. FIG. 4B depicts anchor member 40B which includes four decking attachment holes 306I, 306J, 306K, and 306L each disposed through the body with an opening on the lower surface in line with a midpoint of each longer sidewall, but lacks the decking attachment holes disposed in the corners of the upper surface. These different numbers and locations can provide for additional flexibility, as by allowing for placement where additional securing screws are needed, or where the shape of a deck prevents placement of a screw near a corner of a post (as in a corner against a building) or where the decking 340 cannot accept a screw (due to placement over a joint between planks or fastener securing planking to a deck frame).

Referring now more particularly to FIG. 5, anchor member 30 is depicted in use with post P showing attachment to a deck D. Anchor member 30 is disposed in the internal bore of the hollow post P, which is typically constructed from a vinyl material, such as PVC, but not limited to such. The ridges 312 of the anchor member 30 are disposed in corresponding channels C in the internal sidewalls post P, which are sized to receive and retain the ridges therein.

A plurality of lag screws, depicted in FIGS. 5 as B1 and B2 extend through the anchor 30 and into the material of the deck D to secure the post P in place. It will be appreciated that the head BH of a lag screw B2 may contact the upper surface of the anchor member and the shaft of the screws extend into the material of the deck with at least a portion of the threads securing in the material. Alternatively, and as depicted, a washer (such as a standard circular flat washer W) may be placed on the shaft of a lag screw B1 and contact the upper surface of the anchor. This may be especially useful where the upper surface is defined by reinforcing walls 330 and the voids there between.

It will be appreciated that the deck D needs to be constructed of a material that the screws B can be driven into to thereby secure the post in place. For example, wooden planks or composite decking material such as that commercially available under the trademarks TREX.

It will be appreciated that although only two lag screws B1 and B2 are depicted in the sectional view of FIG. 5, that in a typical installation four lag screws will be used, although embodiments using anchor members such as that depicted in FIG. 4A may use additional screws for increased securing. The anchoring method is not limited to lag screws and other types of fasteners may be used. The present disclosure further includes methods of installing posts to decking, and methods for building or installing deck and stair rails. Such methods include measuring and designing the railing for installation at a location with a surface faced with decking material, and determining the number, height, type and placement of posts for the railing.

Posts are then assembled based on the design, which may include cutting extruded tubing to the appropriate length for the various post, forming tapers 331 on the interior lower edges of a post P to facilitate insertion of an anchor, and cutting or forming appropriate grooves in the interior sidewalls of the post P to receive the ridges of the anchor member. Anchor members with a suitable number and placement of deck attachment holes 306 are then attached to the posts P by placement with a press. Each anchor member 30 maybe inserted using a press that contacts the lower surface 302 and presses the anchor member 30 into the post P. As the anchor member 30 is inserted, the walls of the post P flex to allow ridge 312 to move down the bore of the post until aligns with the channel C. The vertically disposed ridges 315 serve as a guide for the flexion of the sidewall by acting as a fulcrum allowing the walls to expand a predetermined distance 333 thus allowing the broader ledge 312 to engage the taper formed at the end of the post 334 and to slip past the post's blunt end 332. The inset corners 313 provide for additional stress release on the post sidewalls to increase flexion. Once the anchor 30 is inserted a sufficient distance that the ridge 312 aligns with channel C, the sidewalls of the post P snap against the anchor sidewalls with the ridge 312 secured in the channel C. As depicted, anchor sidewall extending above and below the ridge 312 is contacted to provide a secure installation.

The posts P with the installed anchor members 30 are transported to the job site, and a post P is placed at the location for its installation. Alternatively, a post P could be used as a stand-alone post for signs or purposes other than railing. Where appropriate, pilot holes for the screws may be predrilled at the location installed. A plurality of lag screws are then placed through the screw attachment holes in the anchor member from the top of the post P, with one in each hole and driven into the deck D material. Where the lag screws have a polygonal head, a socket extension and ratchet or a large T-driver having a long shaft with a socket bottom that may include a magnet for retaining the screw head and a cross-bar handle may be used to drive each screw into the deck.

Each screw B is placed into the decking 340 and tightened against an upper surface of the anchor member 30. In prior art systems, the use of a thick square metal washer or plate to spread forces out across the surface of the anchor member was required to prevent damage at the center hole of the anchor. In the present methods, no such washer is required. However, to reduce the forces brought against any one point of the anchor member 30 during installation, an installer may install the screws and flat washers individually to retain the post P in place, but not fully tighten screws initially. Once all screws for a particular post P have been installed for that location, the installed screws are then tightened in an appropriate order to fully secure the post P in place. At this point the other components of the railing system can be attached to the post P in the appropriate manner.

While this disclosure has been described using certain embodiments, the present disclosure can be further modified while keeping within its spirit and scope. This application is therefore intended to cover any variations, uses, or adaptations of the disclosure using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practices in the art to which this invention pertains and which fall within the limits of the appended claims.
