[0003] FIELD OF THEINVENTION The present invention relates to an anchor and rail assembly for attaching rails, balustrades, fences and the like to flat roofs and other slab structures such as roof decks, terraces, open balconies, walkways and the like, as well as to sloping surfaces such as stairs and ramps for both indoor and outdoor use, while providing both strength and / or waterproofing. [Background technology]

[0004] 2. Background of the Invention Various methods are known for mounting and waterproofing roof equipment, accessory structures, or the like, such as rails, fences, guard rails, etc., that are attached to sloping or flat roofs, building terraces, roof decks, walkways and ramps, etc. In the roofing industry, problems with water ingress at the mounting points of equipment and accessories abound, particularly when flashings are not incorporated and / or only sealants are relied upon. Various coating methods and their combinations are used as water and moisture barriers on structures such as asphalt roof tiles, injected or laid plastic, or rubber membranes and the like. Currently, increasingly heavy roof structures, such as solar panels, satellite dishes, HVAC equipment, etc., are mounted on the roof, and especially for roof decks, balconies, terraces and the like, glass walls and / or rails are mounted to prevent obstructions from being seen, as would typically be the case with wood, cable or metal fences, for example. These generally heavy structures must also be secured to the roof structure, but because of the loads they generate and the manner in which they are typically attached with anchors bolted through the roof, the structures create a "conduit" for water to penetrate the roof, despite the fact that adhesives and glues are often used to seal the conduit in an attempt to prevent such ingress. Indeed, over time, and as a result of typical repeated roof movement or lifting caused by, for example, settling, temperature changes, and / or high winds, these heavy structures can cause the adhesives or glues utilized to crack, ultimately resulting in roof leaks. As a result, it is difficult for many installers to provide or obtain insurance against water or moisture damage caused by such conventional fastening systems.

[0005] The present invention seeks to overcome this problem by providing a novel fastening system which avoids such problems in a convenient and beneficial manner.

[0006] Similarly, conventional methods for mounting rails, and in particular radius posts or balustrades, on structures including roof structures require the post to pass through the structure, e.g., through the roof sheathing in order to bolt underneath to a beam or rafter in the case of a roof structure. While installing a standard (e.g., square) post to a beam or rafter is a challenge, installing (i.e., attaching) a radius post to a beam or rafter is even more difficult because a round piece of wood (or other post material) cannot seat precisely against the plane of the beam or rafter. Additionally, while waterproofing a standard post is a challenge, waterproofing a radius post is very difficult, requiring, for example, custom radius copper soldered flashings, and is highly vulnerable to leaks.

[0007] Moreover, conventional methods for mounting columns for indoor applications such as indoor staircases, open balconies, walkways, ramps or rails where waterproofing is not required lack a simple yet extremely sturdy, strong and rigid fastening and fastening method that allows the same fastening and fastening means to be easily replaced and reused when the rails and / or handrails need to be replaced. Summary of the Invention [Problem to be solved by the invention]

[0008] It is therefore an object of the present invention to provide a novel anchor and rail assembly for fastening balustrades, fences, glass rails, and / or other roof attachment structures, and / or posts or balustrades of any geometric shape (e.g., square or rectangular, circular, triangular, etc.) to structures such as roofs and the like, which can accommodate heavy loads and provide waterproofing to the fixture or post attachment points.

[0009] It is a further object of the present invention to provide a novel anchor and rail assembly that is relatively simple in design and construction, easy to install and replace or remove, and relatively inexpensive to manufacture.

[0010] It is another object of the present invention to provide a novel anchor and rail assembly that can be used with a variety of roofs or elevated structures, including both flat and steep roofs, as well as roof decks, exterior balconies, terraces, stairs, slopes and the like.

[0011] It is yet another object of the present invention to provide a novel anchor and rail assembly which provides a watertight connection at the assembly attachment points and which is more reliable than prior art systems.

[0012] It is a more specific object of the present invention to provide a novel anchor and rail assembly that can be adapted for indoor use where waterproofing is not required, but where a simple, yet robust, strong, highly effective and rigid fastening and fastening assembly is required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Detailed Description of the Preferred Embodiments Turning now to the drawings, and specifically to Figures 1-7b thereof, there is shown a novel anchor and rail assembly embodying the present invention as described and shown in Applicant's aforementioned U.S. Patent Application No. 15 / 852,733 and International Patent Application No. PCT / US2019 / 018592, more specifically intended for a wide range of fastening applications, particularly for fastening an object to a support structure, which are broadly adaptable to many different fields of use.

[0033] 1-4c thereof show a first embodiment of the present invention including a novel anchor and rail assembly generally designated by reference numeral 10, specifically designed for anchoring roof attachment structures to roofs and other elevated, flat and / or steeply sloping structures such as terraces, balconies, staircases and the like. The main component of the anchor and rail assembly is an anchor base plate generally designated by reference numeral 11, which is preferably made from stainless steel (but can be made from other metals such as aluminum, bronze, etc.), is preferably square or rectangular in shape, and has a top surface 12 and a bottom surface 13. The anchor base plate 11 has an internally threaded central through hole 14, and six spaced peripheral through holes 15 positioned radially outward from the central hole 14 and generally adjacent the periphery of the base plate 11. In this embodiment, the anchor base plate 11 also includes a preferably cylindrical rod or post 16 having an axially extending, female-threaded bore 17 (see FIG. 4b) with an open top end 18 and a closed bottom 19 (FIG. 2), the open top end 18 of which is secured to the anchor base plate 11, preferably via welding, such that the open top end of the bore 17 abuts and aligns with the open bottom end of the central through hole 14 of the anchor base plate 11 (see FIG. 4b).

[0034] As shown in FIG. 3, the anchor base plate 11 of the anchor and rail assembly 10 is typically attached to a roof structure, such as a roof deck, generally indicated at 21, via mechanical fastening elements 20, preferably in the form of nails, bolts, or lag screws, with its column 16 extending through the roof deck 21 and projecting its closed end 19 below the roof deck. The female-threaded aligned holes 14 and 17 serve as anchoring points for mounting an object onto the roof deck 21. In this case, the object is a type of glass rail having a glass panel 22, the lower edge of which is secured within an elongated U-shaped metal channel or shoe 24. FIG. 3 details three consecutively disposed and spaced apart anchor base plates 11, to which are attached at least a portion of two glass panels 22 and two shoes 24. In use, such glass rails can be several hundred feet long. As can be appreciated, depending on the length of each glass rail 22, multiple anchor base plates 11 per glass rail 22 may be required as shown in FIG. 3.

[0035] As best seen in Figures 4a and 4c, an elongated U-shoe 24 has a base wall 23 with a plurality of spaced apart through holes 25 (only one of which is shown). As discussed in more detail below, a mechanical fastener, such as a threaded bolt 26 and washer 27, is used such that the bolt 26 is receivable through the through hole 25 of the U-shoe 24 and into the female-threaded central hole 14 of the anchor base plate 11 and the female-threaded blind hole 17 of the cylinder or rod 16 (Figure 4c) to secure the cylinder or rod 16 to the roof deck 21. The cylinder 16 with its closed bottom 19 serves two purposes: (1) the cylinder 16 provides a relatively strong and rigid anchoring support point for mounting an object on the roof, and (2) the cylinder 16 prevents water from entering into and under the roof deck 21 via the central hole 14 as a result of the blind hole 17 and bottom end 19 of the cylindrical rod 16 being closed.

[0036] 4b shows the use of a square shaped shim plate 28 having a central through hole 29 mounted on top of the anchor base plate 11 such that its central through hole 29 is aligned directly over the internal blind hole 17 of the cylinder 16. The shim plate 28 is used to adjust the height of the shoe 24 to ensure proper alignment of the adjacent shoe 24 and glass rail 22 it supports due to changes in height of the roof deck 21 or the like. Of course, additional shim plates 28 can be used to achieve proper height alignment if necessary.

[0037] As shown in Figures 4a and 4c, the central through hole 25 of the U-shaped channel or shoe 24 contains a step that is sized and configured to receive and support the bolt head and washer 27 of the bolt 26 on the step such that the bolt head of the bolt 26 is aligned below the upper surface 30 of the lower base wall 23 of the U-shaped shoe 24 so as not to abut the bottom edge of the glass rail 22 and possibly crack or damage the bottom edge of the glass rail 22.

[0038] 4a and 4c respectively show an exploded and fully installed cross-sectional side view of an anchor and rail assembly 10 including preferred flashing materials, fasteners and adhesives, and the like, for mounting a glass rail to a roof deck or terrace, or the like. As shown in FIG. 4a, an anchor base plate 11 is positioned on a roof deck 21, which may be wood, metal, or a composite structure as is standard or customary in the industry. The column 16 of the anchor base plate 11 is intended to be inserted through a through hole 31 in the roof deck 21 and a through hole 33 in a conventional rubber roof membrane 32, preferably made from neoprene, which is preferably sandwiched between the anchor base plate 11 and the roof deck 21. Similarly, a conventional rubber roof membrane 34, preferably made from neoprene, is preferably positioned between an optional shim plate 28 and the top surface 12 of the anchor base plate 11, the membrane 34 also including a central hole 36 to allow the bolt 26 to pass through the membrane 34. Additionally, a sealant, cement, caulk or adhesive layer 38 is shown which would normally be applied to the bottom surface 13 of the anchor base plate 11 to adhesively bond and seal the adhesive layer 38 to the roof membrane 32.

[0039] 4c, adhesive, caulking, cement or glue 40 (and / or optionally clips) are also applied to the interior surface of the U-shaped metal channel 24 to surround the lower end of the glass rail 22 received therein. Also shown therein, the anchor baseplate membrane 34 extends across the anchor baseplate 11 and has its ends sealed against the roof membrane 32, thereby sealing the screw holes and the remainder of the anchor baseplate 11. As can be appreciated, these flashing materials and adhesives help waterproof the assembly and protect the roof from leaks.

[0040] As mentioned previously, this is specifically the point of attachment of the object to the roof, which in this case refers to the attachment of the glass rail shoe 24 to the column 16 of the anchor base plate via the bolt 26 and the threaded blind hole 17 into which the bolt 26 is received. Because the hole 17 is a blind hole or hole and the bottom end 19 of the column 16 is closed, any water that could possibly get between the glass panel 22 and the U-shaped channel 24 and enter the hole 17 in the column 16 is completely blocked from penetrating the roof deck 21.

[0041] 5a and 5b show a second embodiment of an anchor and base plate assembly 10' as well as an exploded and fully installed cross-sectional side view, respectively, of this second embodiment of the anchor and rail assembly 10'.

[0042] The elements shown in this second embodiment are the same as those shown in Figures 4a and 4c, except that the cylinder 16' includes a narrow neck 36 and the base plate 11' includes a non-threaded central hole 14', both of which are otherwise identical to the base plate 11 and cylinder 16 shown in the previous embodiment. In Figures 4a and 4c, the upper end 18 of the cylinder 16 would typically be welded to the bottom surface 13 of the anchor base plate 11. However, in Figures 5a and 5b, the narrow neck 35 is intended to be received within the non-threaded central hole 14' of the anchor base plate 11', and this configuration results in a more sturdy and stronger joint. The stronger joint results from the fact that when the anchor plate 11' and post 16' are welded together, the respective central holes 14' and female threaded holes 17' are held in proper axial alignment by the reduced neck 36 of the post 16', which is received and extends into the non-threaded central hole 14'.

[0043] 6a and 6b show a third embodiment of an anchor and base plate assembly 10'' as well as exploded and fully installed cross-sectional side views, respectively, of this third anchor and rail assembly embodiment. The elements shown in this third embodiment are the same as those shown in Figs. 5a and 5b, except that the lower portion 37 of the cylinder 16'' is externally threaded but is otherwise identical to the cylinder 16'. In this embodiment, a nut 39 and washer 41 are threaded onto the externally threaded surface 37 of the cylinder 16'' such that, in the fully assembled condition shown in Fig. 6b, the nut 39 and washer 41 are tightened against the lower surface of the metal roof deck 21' to provide a more rigid point of attachment while at the same time preventing roof leakage at the attachment point through the blind hole 17' and closed end 19 of the cylinder 16''.

[0044] 7a and 7b show a novel accessory support stand 42 for the various anchor plate assemblies shown herein that allows a user to lift and support spaced objects above the anchor base plate. The accessory support stand 42 includes an upstanding, preferably metal, square tubular body member constructed of a preferably metal, square or rectangular planar base 44 and four side walls 43 joined at one end to the planar base 44 by welding. A drain hole 45 is provided in the base of one side wall 43 to allow water to drain therefrom. The base 44 has a central hole 49 (FIG. 7b) that can be aligned with the female threaded hole 17' of the cylinder 16'' and the threaded stem of the bolt 26 can be threadably received in the female threaded hole 17' to secure the support stand 42 to the anchor base plate 11''. At least one pair of horizontally aligned holes 46 are formed in opposing side walls 43 of the upright tubular body, through which a threaded bolt 47 can be fitted to secure an object to one of the side walls 43 of the support stand 42, as best shown in Fig. 7b. In this case, the U-shaped channel 24' is provided with a recessed through hole 25' in one of its side walls, rather than in its base wall 23', as shown in the embodiment of Figs. 1-6. The bolt 47 is held at its opposite end (i.e. at the free end of its threaded shaft extending through the side wall hole 46) by an additional nut 47 and washer 48 to secure the U-shaped channel 24'' in an elevated position relative to the anchor base plate 11'' and roof member 21', offset relative to the central blind hole of the anchor base plate 11'' via its bolt head held in the step of the channel through hole 25'.

[0045] Figures 7c and 7d show a modified accessory support unit of the type shown in Figures 7a and 7b, serving as an end post for a line cable type rail system. Specifically, an accessory post 42' as shown in Figure 7c. The accessory support stand 42' includes an upstanding, preferably metal, square tubular body member constructed of a preferably metal square or rectangular planar base 44' and four side walls 43' joined at one end to the planar base 44' by welding. A large access hole 65' is provided at the base of one side wall 43' for a wrench or other tool to access its interior chamber. The base 44' has a central hole 49 (Figure 7d) which can be aligned with the female threaded hole 17' of the column 16'' and the threaded stem of the bolt 26 is threadably received within the female threaded hole 17' to secure the support stand 42 to the anchor base plate 11''.

[0046] As can be seen, a tool can be used to engage the heads of the bolts 26 and tighten the bolts 26 down to secure the support 42' to the anchor base plate 11'. As also shown in Fig. 7d, two pairs of horizontally aligned holes 46' are formed in opposing side walls 43' of the upright tubular body, through each of which an end of the cable 327 passes and is secured via a conventional end cap 329. The end of the top rail 360 is secured to the top of the post 42' via a threaded bolt 339 received in a threaded hole in the horizontal top wall 340.

[0047] 8a-8e disclose a fourth embodiment of an anchor and rail assembly 10''', in which an anchor base plate 11''' has a lower square-shaped planar base portion 50 and a truncated pyramidal upper portion defining four upwardly tapering side walls 51 and a square-shaped flat top wall 52. Top wall 52 has a centrally arranged blind hole 54 that is female-threaded, and each of side walls 51 has a recessed generally cylindrical notch or cavity 55 that extends through bottom 50 and then opens onto a through hole 56 that opens onto its bottom surface 57.

[0048] As seen in Figs. 8d and 8e, which respectively show a partially exploded and fully installed cross-sectional side view of this fourth embodiment of the anchor and rail assembly, the top wall 52 is used to secure the object 24 to the roof structure via its female-threaded central blind hole 54. A lag screw 53 is inserted into each of the side wall through holes 55 to affix the anchor base plate 11''' to the metal roof deck 21'. The side wall cavity 55 is then covered by a generally cup-shaped cap 61 having a radially extending flange 62 intended to close and seal the cavity 55 and prevent water ingress. As in the other embodiments, the roof membrane 32 is deployed between the anchor base plate 11''' and the metal roof structure 21', and the anchor base plate membrane 34 is also arranged directly on the anchor base plate 11''', with its ends extending above the roof deck membrane 32. A bolt 26 and a washer 27 secure the U-shaped support shoe 24 to the anchor base plate 11'''. The bolt heads and washers 27 of the bolts 26 are received on the through hole steps 25 of the base wall 23, and the bolts are then threadably received within the threaded blind holes 54 to secure the anchor base plate 11'''' to the metal roof deck 21'. An adhesive layer 38 also bonds the anchor base plate 11'''' to the roof membrane 32 to enhance the waterproof performance of the assembly.

[0049] 9a-9j, there are shown several embodiments of novel anchor and fastener assemblies (hereinafter generally referred to as "anchors" or "anchor assemblies") according to the present invention, as shown and described in applicant's previously filed continuation-part International Patent Application PCT / US2019 / 018592. As shown in FIGS. 9a-9c, the anchor assembly 110 is a countersunk screw anchor, which is particularly useful in the building industry for a myriad of uses. The countersunk screw anchor assembly 110 includes a preferably planar base plate, flange or washer 111 having an upper surface 112, an opposing lower surface 113, and an optionally female-threaded central aperture 114 extending therethrough. Additionally, the screw anchor assembly 110 also includes a male-threaded post, preferably in the form of a screw or lag screw 116 secured to the anchor base plate 111 and extending downwardly from the lower surface 113 of the base plate 111. 9b, the upper shaft of the screw 116 includes an axially extending, female-threaded central bore 117 that is integral with and axially aligned with the central opening 114 of the base plate 111. The bore 117 has a diameter smaller than the outer diameter of the male-threaded upper shaft of the screw 116.

[0050] The hole 117 in the screw 116 is a blind hole with an open top end defined by the hole 114 in the flange or base plate 111, and a closed bottom end 119 in the shaft of the screw 116. The screw 116 and base plate 111 are also preferably joined together to form a one-piece combined anchor and fastener assembly or component. The screw 116 can be secured to the base plate 111 via welding, a press fit connection, or by any other fastening means that should ensure that the screw 116 and base plate 111 are secured and rigidly fastened together to provide a strong and sturdy anchor.

[0051] For this embodiment and other embodiments described herein, as shown and discussed below in connection with the installation and use of the anchors of the present invention, a fastener, typically in the form of a bolt 26 having an enlarged head and a threaded shaft together with a washer 27, as previously discussed herein and in applicant's parent application Ser. No. 15 / 852,733, can be threadably received within the hole 117 for holding, fastening and fastening an object to the anchor such that the object or a part thereof or associated attached structure therefor is immediately and securely held against the upper surface of the anchor base plate 111. This is preferably accomplished by providing a through hole within the object, a part thereof or associated attached structure therefor, and the threaded shaft of the bolt is tightened after the bolt is threaded into the hole 117 or the like of the anchor and passes through the through hole to securely fasten the object to the anchor.

[0052] 9d and 9e show a modification of the embodiment of the planar anchor shown in FIGS. 9a-9c whereby recessed countersunk screw slots or ports 143 are formed in the base plate 111 on either side of its central hole 114 which extends below and into the upper outer smooth enlarged head 144 of the lag screw planar anchor 110' on either side of its central hole 117 so that a flat head screwdriver or other tool (not shown) which inserts into said slots 143 can easily rotate the male threaded shaft of the screw 116 to thread the anchor 110' into or out of its intended supporting structure if it needs to be repositioned, for example, within a building supporting structure.

[0053] 9f and 9g show another modification of the screw anchor assembly shown in FIGS. 9a-9c where instead of utilizing a flat head screwdriver port 143, an Allen key port 145 is provided. More specifically, a countersunk hexagonal head space is provided above the upper end of the blind hole 117 in an upper outwardly smooth enlarged head 144 of the lag screw anchor 110 that extends downwardly from the upper surface 112 of the washer 111. The enlarged cylindrical head 144 of the lag screw anchor 110 has a hexagonal inner wall surface 146 that defines an Allen key port 145. The Allen key port 145 is designed to receive an Allen key (not shown) by which the countersunk screw anchor 110 can be easily threaded into and removed from a supporting structure as described and shown in more detail below.

[0054] In yet another embodiment of the screw anchor assembly of the present invention, a hex head lag screw anchor 210 is provided having a hex nut 250 secured atop the upper surface 212 of the base plate 211, as shown in Figures 9h-9j. The hex nut 250 serves the same purpose as a screwdriver slot, Allen key port, or the like, whereby a tool such as a socket wrench (not shown) configured to grip the hex head can be used to facilitate threaded engagement or removal of the hex head into a supporting surface. The external hex nut 250 is preferably integrally joined to the base plate 211, such as by welding, to form a one-piece component. As best shown in Figure 9i, the external hex nut 250 contains a female-threaded central through hole 252 that is axially aligned with the central hole 217 of the lag screw 216 and the hole 214 of the base plate 211. Although anchor 210 is shown and described as having a hexagonal nut 250, other polygonal or geometric shapes are possible and contemplated by the present invention and as further disclosed below.

[0055] 10a-10k show several different preferred arrangements in which the anchor assemblies of the invention are utilized in combination with a railing or post assembly to securely attach the railing to a base support or other structure for outdoor (e.g., roof or terrace) and indoor (e.g., staircase or balcony) applications that avoid problems associated with conventional railing installations (e.g., waterproofing, anchoring, and / or fastening). The arrangements provide the ability to simply install a standard railing. Importantly, the inventive arrangements provide the ability to install a radius post (i.e., a round post) as easily as a standard post (i.e., a square post). As is known, conventionally, installing a radius post to a base support or other structure to which a post is to be attached, such as a roof structure, is very difficult because a round piece of wood (or composite post) cannot seat accurately on a flat beam. In that regard, where the structure must be waterproofed, it is very difficult to waterproof both conventionally installed round posts and standard posts. One method of flashing a radius column requires soldering custom radius copper flashings, which are highly vulnerable to leaks, whereas by using the anchor assembly of the present invention, a radius or round column can be installed in a structure such as a roof structure, deck, or staircase in the same manner as a standard or square installation.

[0056] As shown in the embodiment of FIG. 10a, the anchor 10'' shown in FIGS. 6a and 6b is shown. The anchor 10'' has an anchor base plate 11' with an internally threaded central through hole 14', and an at least partially externally threaded cylindrical rod or post 16'' having an axially extending internally threaded blind hole 17' with a reduced neck open top end 18 and a closed bottom 19, which is secured to the anchor base plate 11', preferably via welding, such that the open top end 18 of the hole 17' is aligned in abutment with the open top end of the central through hole 14'. As shown, the externally threaded cylinder 16'' extends through the roof deck 21' with its closed end 19 projecting below the roof deck. The anchor base plate 11' is fastened to the support 21' by screws 20. A nut 39 and washer 41 are received on the male threaded lower end 37 of the post 16'' to securely fasten the handrail or post assembly, generally indicated at 120, to the anchor base plate 11' and then to the support 21 (e.g., a roof deck).

[0057] As noted above, this embodiment is particularly suited to structures to be waterproofed, such as roof decks, although the invention is not so limited. Although not shown, flashing materials such as those illustrated in Figures 6a and 6b would typically be applied to both this embodiment (Figure 10a), as well as the embodiments shown below.

[0058] On the other hand, as shown in FIG. 10b, where water ingress is not an issue, such as when the part is used indoors, such as for posts, staircases and railings for mounting to floors or interior staircases, open balconies, or concrete floors, the threaded hole 17''' in the cylinder 16''' has an open bottom 19''' in addition to its open top end 18''' to define a through hole 17''' rather than a blind hole 17' as shown in FIG. 10a.

[0059] Regardless of the embodiment shown, the female threaded aligned anchor base plate and post hole serve as an anchor point for fastening the railing or post assembly 120. The railing or post assembly 120 includes a railing 122 (sometimes referred to in the building industry as a spindle, pillar, or picket), which may comprise wood, such as mahogany, cedar, pine, etc., metal, or a synthetic material, such as plastic or other composites. Additionally, the post 122 is shown as square-shaped, but is not limited thereto, and may be any known geometric shape, such as, without limitation, circular, triangular, rectangular, pentagonal, hexagonal, flat, etc. As shown, the post 122 optionally includes a threaded metal rod 124, which is preferably installed within a centrally located through hole 126. The threaded rod 124 as shown is preferably a ½ inch threaded rod, but may be larger or smaller to fit the immediate application or to accommodate the diameter of the threaded and aligned holes of the anchor and post assembly.

[0060] The top 128 of the post 122 is preferably recessed in its center to accommodate a nut 130 and washer 132 for attachment to the top end 134 of the threaded rod 124. Additionally, an optional post cap 136 may be placed to cover the top 128 of the post once the nut 130 and washer 132 are attached to the top end 134 of the threaded rod 124. As can be appreciated, a top rail 360 (see FIG. 7d) may alternatively be utilized which would have an extended length to cover the tops of multiple spaced apart handrails or posts 120. The bottom end 138 of the threaded rod 124 protruding from the bottom 140 of the post 124 is threaded into the female-threaded aligned holes 14, 14' and 17, 17', 17''' to secure the post mount 120 to the anchor base plate 11, 11' and thus to the support structure 21. Again, the assembly means includes an optional square shaped shim plate 28 with a central through hole 29 mounted on top of the anchor base plate 11, 11'. The central through hole 29 of the shim plate is thus aligned directly over the internal hole 17, 17', 17''' of the column 16, 16', 16''', regardless of whether the hole 17, 17', 17''' is a blind hole 17, 17' for waterproofing application (FIGS. 10a, 10c-10f) or a through hole 17'''' where no waterproofing is required (FIG. 10b). The shim plate 28 is used to adjust the height of the column 122.

[0061] In the embodiment shown in Figures 10a, 10b and 10e, the nut 39 and washer 41 are attached to the male threads 38, 38''' of the cylinders 16, 16'', whose lower ends 19, 19''' extend through and under the structure 21', as opposed to the smooth cylinders 16, 16' of Figures 10c and 10d. Thus fully assembled, the nut 39 and washer 41 are tightened against the lower surface of the structure 21' to provide a stronger attachment point while at the same time (again in configurations where watertightness is required) preventing leakage at the attachment point through the blind holes 17, 17' and closed ends 19 of the cylinders 16, 16'. The use of the anchor and rail assembly avoids the need for the post attachment to pass through the structure to attach to the beam or rafter below, and the use of conventional means to seal the post attachment 120 against water, particularly when the post attachment is not a standard square or rectangular shape (e.g. radius column).

[0062] FIG 10c shows an embodiment similar to FIG 10a, except that the anchor base plate 11' has a smooth cylinder 16' with a blind hole 17', and a metal rod 124' with a conventional Allen key port 145 recessed into its upper end, the support structure includes two layers of wooden decking 21', 21' into which the cylinder 16' is embedded, and the anchor base plate 11' rests on top of the decking 21 and is coupled thereto via screws 20 that extend into the bottom layer 21. As previously described, the Allen key port 145 has polygonal side walls to allow an Allen key to be engaged therein, and has a somewhat similar configuration to allow the threaded rod 124' to be easily and conveniently rotated into the threaded hole 17'.

[0063] FIG. 10d shows a further embodiment similar to FIG. 10c, except that an anchor base plate, specifically the type of countersunk screw anchor of FIG. 9a, is used to provide a handrail 122 with an internally threaded hole 117 at its bottom end 140. Thus, rather than providing a handrail 122 with a threaded blind hole, a countersunk screw anchor 110 can be screwed into the top and / or bottom end of the handrail so that its flange sits flush with one or both of its ends. The threaded blind hole 117 of the screw anchor 110 would then serve as the threaded internal hole of the handrail. In this embodiment, the upper end of the threaded rod 70 is partially receivable within the blind hole 117 of the countersunk screw anchor 110 affixed to the bottom end 140 of the handrail 122, and its lower part is receivable within the blind hole 17' of the anchor base plate 11' to secure the bottom end 140 of the handrail flush with the upper surface 12' of the anchor base plate 11'.

[0064] FIG. 10e is a further embodiment of the invention similar to FIGS. 10c and 10d, except that an Allen key port 145' is provided in a blind hole in the anchor base plate instead of the handrail, and the support structure 21' is a metal panel.

[0065] Figures 10f, 10g, and 10h show an alternative method for supporting a post 122 utilizing a screw anchor as shown in Figures 9a-9j. As shown in Figure 10f, the screw anchor 110 of Figure 9f is utilized to support a post 120. Meanwhile, Figures 10g and 10h utilize the hexagonal head screw anchor 210 of Figures 9h-9j. A washer 28 is optionally used in a manner similar to the washer 28 shown in Figures 10a-10e, and when fully installed, the washer 28 abuts the bottom 140 of the post 122. As a result, in Figure 10g, the bottom 140 of the post should then abut the top of the elevated hexagonal head 250, a distance above the anchor base plate or flange 211 equal to the height of the head 250. This allows a greater separation between the post 122 and the support 21 so that any water on the support 21 cannot escape into the post. 10h, washer 28' has a central hole 29' with a diameter slightly greater than the width of raised hex nut head 250 and a height equal to the height of hex nut head 250 so that hex nut head 250 fits into central recess 29' of washer 28' effectively turning the hex screw anchor into a water-drain screw anchor, with bottom end 140 of post 122 abutting the top of flange 211 which then rests essentially flush against support 21. Optionally, base plate 211 may have a sealant layer 35 on its bottom surface 213.

[0066] Figures 10i and 10j show two further embodiments in which a steel post 120' is provided in place of the wooden post 120, but which have a generally similar structure and utilize the same anchor and fastening system of the present invention. However, in these two embodiments, the post 124' comprises a steel hollow square tubular handrail or post 222, which in Figure 10i houses a female-threaded metal rod 124', the upper end of which has an Allen key port 145 formed therein for easy rotation of its bottom end within the blind hole 17' of the post 16' of the anchor 10'. Adjacent to the upper end of the rod 124, a horizontal guide member 226 is affixed by welding to the tubular post 222, which has a central hole 227 through which the rod 124' passes with some clearance to allow rotation via the Allen key port 145. The rod 124' is supported by a washer 132 and a nut 130, which is fully tightened after the post 120' is threaded into the anchor 11'.

[0067] The bottom of the post 222 is provided with a lateral base member 223 to which the bottom of the tubular post 222 is affixed, the bottom of the tubular post 222 also having a central aperture 228 through which the rod 124' also passes with clearance to allow rotation via the Allen key port 145. The bottom plate 223 is intended to seat on top of the upper surface 12 of the anchor base plate 11', although an optional washer or shim plate 28 having a central hole 29 can be inserted therebetween. The bottom plate 223 has a plurality of spaced apart threaded through holes 224 formed therein through which set screws 225 can be threadably adjusted to level the post 120' as needed.

[0068] As shown in Figure 10j, steel column 120'' is generally the same as column 120 shown in Figure 10i, except for a modified base member 224' which is arranged outwardly of column 122' adjacent its bottom end and thus is not used by itself to center rod 124'. Instead a spacer plate or disk 229 is rigidly mounted on threaded rod 124' adjacent its bottom end, the bottom end being sized to have a width narrower than the inner wall of column 222' to provide clearance between the bottom end and the inner wall of column 222' so that rod 124' can rotate and be secured to anchor base plate 11' as previously described.

[0069] Figure 10k depicts an embodiment having a handrail or post 120 that is the same as that shown in Figure 10c, but is supported by the pyramidal anchor base plate of Figures 8a-8e, with the lower threaded end 138 of the post 120 being threadably received within the threaded blind hole 54 of the anchor base plate 111'.

[0070] For safety reasons, it may be advisable to connect or interconnect the posts through the use of one or more mid-rail cables, each running laterally through spaced apart posts. To do so, the handrail or post assembly is configured with an opening or port to pass through the mid-rail made from the line cable, for connection from one post to another or to some other building support structure, such as the wall of an adjacent building, once the anchor and rail assembly and the post attachment are secured to the support structure. Once installed, the cable or cables passed through the port located in the post act as a safety fence. Additionally, the post of the present invention may be configured to allow the cable to pass through its entire longitudinal length as a full length pass. In this way, the cable may pass through the entire length of the post, starting at a port at the top and passing through a port at the bottom, to serve the purpose of firmly attaching the post, or additionally to act as a conduit for electrical wires or lighting to illuminate the structure or part thereof, or perhaps even to act as a fluid conduit to heat the handrail or its upper handrail.

Similarly, the lower end of the handrail includes a similar pedestal extension 350 mounted on the bottom of the threaded rod 324, the pedestal extension 350 having an upper plate 351, a lower plate 352, and a hollow central column 353 therebetween, the pedestal extension 350 resting on the shim 28 and then on the anchor base plate 11'. A pair of plates 352 may also be placed between the pedestal 350 and the base plate 11' as shown for proper spacing or stability. Further similar to the embodiment of Figures 11a, 11b, 12, 13 and 14, the handrail (320, 420, 520, 620) and threaded rod 324 also include respective conduits 326, 325 for the passage of the cable 327.

[0076] FIG. 15a depicts a modified configuration of a handrail assembly 720 having an axially disposed threaded rod 324 and an anchor baseplate assembly 10''', with a column 16''' having a pair of blind holes 317''' at either end. In this embodiment, the user has the option of fastening the anchor baseplate assembly 10''' from below the support 21 via a threaded rod inserted through the base support 21, which can be threadably inserted into the downwardly opening threaded hole 317''' with a nut and washer to fasten the anchor baseplate 11''' from below the support structure 21 (not shown). The anchor baseplate 311' also has a second blind hole 17''', at the end of which the threaded rod 324 is threadably received and fastened to the anchor baseplate 311'.

[0077] Figure 15b depicts two further modified arrangements similar to that of Figure 15a, but where handrails 324', 324'' include threaded holes 317 located at either end. The post on the left 324' is a solid smooth cylinder and the post on the right is a hollow smooth cylinder 324''.

[0078] The handrails 324', 324" are shown joined together side-by-side by a top rail 340 and a pair of enlarged-head threaded bolts 26 whose threaded shafts are inserted into a pair of through holes 323 in the top rail 340 for threadedly engaging with through holes 317 at the upper ends of the rods 324' and 324". The threaded holes 317 at the lower ends of the rods 324' and 324" are received within threaded holes 317 in threaded posts 316 that extend upwardly from the anchor base plate 311.

[0079] It should be understood that the above-described drawings merely illustrate the application of the principles of the present disclosure. Numerous modifications or alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present disclosure. Thus, while the present disclosure has been specifically and specifically illustrated and described above, it will be apparent to those skilled in the art that many modifications, including but not limited to changes in size, material, shape, form, function and manner of operation, assembly and use, may be made without departing from the principles and concepts described herein.

[0080] For example, the configurations, sizes, and shapes of the anchor and rail assemblies and their components shown in the various embodiments can be substituted for one another for specific applications when necessary or desirable. For example, the anchor base plates, screw anchors, and railings can be circular, rectangular, polygonal, or have irregular perimeters such as L-shaped or U-shaped, and the posts can be cylindrical, polygonal, or other shapes, and can be in the form of various fasteners such as screws or bolts. The railings, also referred to in the art as spindles, pickets, posts, etc., can also be of any desired configuration and size, and can be in the form of panels such as glass or plastic, or alternatively solid panels.

[0081] As briefly mentioned when discussing FIG. 4a, it is important to use cylindrical mechanical fasteners with "parallel" threads to attach objects onto support structures through the female-threaded cylindrical blind or through holes of the various embodiments described herein. More specifically, this type of mechanical fastener has so-called "parallel" threads, i.e. bolts with a head and a cylindrical threaded shaft, as well as cylindrical rod-shaped studs without a head. This is to distinguish it from so-called "cone-shaped" threads, which have "tapered" threads. The use of such cylindrical bolt or stud fasteners with parallel threads ensures a strong joint and the versatility to accommodate fasteners of varying lengths and widths to achieve different degrees of holding force through threaded reception in the female-threaded cylindrical blind hole of the balustrade, which also has straight edges. In contrast, the mechanical fasteners used to attach the anchor base plate to the support through the auxiliary holes 15 may be of any type, including generally screws with "tapered" threads.

[0082] As can be appreciated from the foregoing, the shape and number of anchor base plates, screw anchors, handrails, rails, cable rails, etc., whether male threaded or smooth, the shape, type and number of anchor base plate posts, the use of non-threaded through holes, threaded blind holes, and their locations may also be modified depending on the particular details of a particular application, such as the nature, size and material of the roof, building or other supporting structure, such as metal, wood, or some other composite. Similarly, it is contemplated that the types of fasteners, membrane flashing materials and sealants may be selected to be interchangeable. Additionally, elements of the various embodiments may be substituted for one another where appropriate.

[0083] Additionally, the anchors, aside from being raised hex screw anchors, preferably utilize a flat head screw slot or Allen key port to secure or remove the anchor from the support structure, although other means such as star bits or the like may alternatively be used to assist the user in threading and / or removing the anchor from the building support.

[0084] The materials of the components of the anchor and rail assembly, such as the base plate, screw anchors, and posts, can also be made from a variety of materials, including metals, such as stainless steel, aluminum, bronze, and copper, as well as plastics or composite materials. It is also preferred that the base plate and its posts, as well as the screw anchors and their flanges, are integrally formed as one-piece components. However, it will be understood that the posts or screws can be secured to the anchor base plate or screw flanges via welding or other means. Similarly, the rail or handrail can be made from a variety of materials, such as wood, various metals, including wrought iron, or plastics and composite materials.

[0085] Thus, while specific embodiments of the invention have been described, it is not intended that the invention be limited thereto, as the invention can be as broad as the prior art, and the specification is intended to be read in the same manner.
