Definitions
- the invention is related to fasteners and methods used to assemble a railing, balustrade or fence. More specifically, the invention is concerned with a fastener that can be affixed to opposing ends of a picket or baluster in order to attach the picket to a pair of rails for assembly of a picket fence or balustrade.
- Picket fences are in widespread use to demarcate property lines and to enclose specific spaces within a property such as a patio, backyard deck, pool, and the like.
- Such fences incorporate a variety of designs but generally consist of a sequence of vertically aligned, elongate balustrades or pickets that are fastened perpendicularly to horizontal support members or rails with intervening spaces between any two pickets.
- An early version of the picket fence was comprised of flat rectangular pickets with pointed top ends attached to one side of upper and lower horizontal support members so that the pointed ends of the pickets were exposed and disposed above the upper horizontal member.
- This design and construction technique presented not only a pleasing, aesthetic appearance but also provided a functional characteristic as the top pointed ends of the pickets discouraged climbing over the fence.
- picket fence is comprised of elongate, rectangular pickets or balustrades that are attached at opposing ends thereof to upper and lower fence rails.
- the upper fence rail is located over the top end of the pickets and functions as the uppermost surface or portion of the fence.
- the pickets are attached to the fence rails by various methods and devices.
- the ends of the pickets can be configured into a particular shape or design that is received into cooperating apertures or bores located in the fence rails, such as screw threads formed onto the ends of the pickets and around cooperating bores of the fence rails so that the pickets can be screwed into said fence rails.
- such method of attachment provides an inadequate means of affixing pickets to fence rails if the fence components are manufactured of certain materials that have limited load-bearing capabilities such as plastic or vinyl.
- the pickets can also be attached by fasteners such as nails or screws to the fence rails with said means of attachment strengthened as needed by the use of brackets and the like.
- This method of attachment presents less than a satisfactory appearance as nails and screws may be visible if not properly countersunk and if any brackets are not seated within a depression so that said fasteners and brackets are flush with the surface of the pickets and fence rails.
- the subject of the instant invention presents a variety of fasteners that can be used for attaching pickets to upper and lower fence rails and a method for such assembly in order that a picket fence that is stable and secure can be erected using a variety of fence construction materials while also providing the fence with a pleasing and aesthetic appearance.
- Such fastening means is comprised of fasteners that are inserted at a first portion or end thereof into opposing ends of a picket and inserted at a second portion or end thereof into adjacent fence rails.
- An aspect of the invention which will be described in greater detail hereinafter, relates to the field of fasteners and methods used to assemble fences. More specifically, this version of the invention is concerned with a fastener that can be affixed to opposing ends of a picket in order to attach said picket to adjacent fence rails for assembly of a picket fence.

- the fastener is comprised of a conical member with screw threads surrounding the exterior thereof and a rectangular member connected to a wider end of the conical member.
- the fastener is comprised of a conical member with surrounding screw threads and a hexagonal member connected to a wider end of the conical member.
- a picket fence is assembled by inserting the rectangular or hexagonal member of a fastener into a bore formed into each end of a picket so that the ridges thereof frictionally engage the sidewalls of said bore and then inserting the cylindrical or conical member of the fasteners, which extend beyond the pickets, into cooperating bores of the fence rails.
- the pickets can be anchored to the fence rails by rotating said pickets so that the screw threads of the cylindrical or conical member engage the surrounding sidewall of cooperating bores in the fence rails.
- the spacing of the pickets between the fence rails can be facilitated by use of a measuring guide releasably attached to the side of a container for storage and transport of the pickets.
- the measuring guide is comprised of two sidewalls that are perpendicularly attached with a series of apertures located in a sidewall thereof.
- the sidewall with said apertures located therein can be placed over two fence rails so that bores can be drilled into the fence rails using said apertures as a guide.
- a picket fence that is stable and well constructed can be assembled quickly and efficiently.
- Fasteners are fabricated from exemplary materials including plastics, nylon, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane, or alternatively, nondeformable materials such as metals including, but not limited to aluminum, zinc, galvanized steel and stainless steel.
- the pickets and fence rails can be comprised of a variety of materials, such as wood, plastic, vinyl, various metals and the like.
- a fastening means and method for assembling picket fence in which a fastener includes a cylindrical or conical member and a rectangular or hexagonal member connected thereto. Screw threads or ridges surround the exterior of the cylindrical or conical member and ridges surround the rectangular or hexagonal member; and a plurality of pickets with bores formed into opposing ends thereof for receipt of individual fasteners.

- a first fastener 10 is located between the top end of the picket 44 and an upper fence rail 48
- a second fastener 10 is located between the bottom end of the picket 44 and a lower fence rail 48 .
- the cylindrical member 12 of each fastener 10 is disposed toward a cooperating, cylindrical bore 50 of a fence rail 48
- the rectangular member 14 of each fastener 10 is disposed toward a cooperating, rectangular bore 46 of the picket 44 .
- the fasteners 10 are attached to the picket 44 by means of the rectangular members 44 of the fasteners 10 inserted into the rectangular bores 46 located at opposing ends of the picket 10 .
- the ridges 26 of the rectangular member 44 frictionally engage the communicating sidewalls surrounding the bores 46 so that the fasteners 10 are securely anchored within the bores 46 to the picket 44 .
- fasteners 10 having clockwise-fastening screw threads 20 are inserted into first bores 46 of pickets 44 and fasteners 10 having counterclockwise-fastening screw threads 20 are inserted into second bores 46 of pickets 44 on opposite ends of the pickets 44 .
- the picket 44 with the fasteners 10 secured thereto can be attached to the fence rails 48 by inserting the exposed cylindrical members 12 of the fasteners into cooperating cylindrical bores 50 of the fence rails 48 and rotating the picket 44 so that the screw threads 20 of the cylindrical members 12 engage the sidewalls of the bores 50 as illustrated in FIG. 7.
- Preparing the picket 44 by inserting fasteners 10 of clockwise and counterclockwise fastening types in respective opposite ends thereof assures that the fasteners 10 engage the upper rail and lower rail at the same time by the same rotational movement to secure the pickets to the rail.
- a plurality of pickets 44 can be aligned for attachment to upper and lower fence rails 48 to construct a picket fence of varying length and secured to said rails 48 as described previously.
- the pickets 44 and the fence rails 48 are comprised of material that is lightweight, durable, rigid, and resistant to corrosion and oxidation, such as various wood products, metals and alloys, plastic, vinyl, composite materials, and the like.
- a third embodiment of a fastener 52 is illustrated in FIG. 9 as having a conical member 54 with surrounding screw threads, said conical member 54 tapering from a narrower end to a wider end with said wider end connected to a rectangular member 56 .
- the fastener 52 is aligned between an end of a picket 44 with cooperating bore 46 and a communicating side of a fence rail 58 .
- Two types of fasteners 52 are desirably provided, a first in which the conical member 54 has clockwise-fastening threads, and a second in which the conical member 54 has counterclockwise-fastening threads.
- the picket 44 is attached to upper and lower rails 58 by first inserting the rectangular member 56 of the fastener 52 into the bore 46 at opposed ends of the picket 44 so that the rectangular member 56 frictionally engages the surrounding sidewalls of the bore 46 and anchors the fastener 52 to the picket 44 .
- the picket 44 with the fastener 52 disposed therein is placed adjacent to the rails 58 in perpendicular relation and rotated while pressing the conical members 54 of the fasteners 52 against the rails 58 until the conical members 54 engage the rails 58 , initially securing the fasteners 52 and picket 44 to said rails 58 .

- a clockwise-threaded fastener 52 is attached to one end of the picket and a counterclockwise-threaded fastener 52 is attached to the other, such that rotating the picket 44 in one direction engages both of the rails 58 at the same time to secure the picket 44 to the rails 58 .
- the conical members 54 of the fasteners 52 can be attached to the rails 58 with or without a pilot hole formed in said rails 58 . It may also be desirable under limited circumstances to further secure the rectangular member 56 of the fastener 52 to the picket 44 by inserting a screw 55 through a sidewall of the bore 46 of the picket 44 , for example.
- the fastener 60 is comprised of a conical member 62 with surrounding screw threads.
- the conical member 62 tapers from a narrower end to a wider end with said wider end connected to a hexagonal member 64 .
- Two types of fasteners 60 are desirably provided, a first in which the conical member 62 has clockwise-fastening threads, and a second in which the conical member 62 has counterclockwise-fastening threads.
- the fasteners 60 are attached to each end the picket 44 by inserting the hexagonal members 64 into the bores 46 at opposed ends of the picket 44 until the sidewalls of the hexagonal members 64 engage cooperating sidewalls of the bores 46 , and the conical members extend above the end of the picket 44 .
- a clockwise-threaded fastener 60 is attached to one end of the picket and a counterclockwise-threaded fastener 60 is attached to the other.
- the picket 44 having a fastener 60 secured at each end thereof is aligned between upper and lower rails 58 so that the conical members 62 of the fasteners 60 engage the rails 58 , initially securing the fasteners 60 and picket 44 to said rails 58 .
- the fasteners 60 are then screwed into the rails 58 by pressing the conical members 62 against the rails 58 and rotating the picket 44 until the conical members 62 are completely disposed within the rails 58 .
- the conical members 62 of the fasteners 60 can be attached to the rails 58 with or without a pilot hole formed in said rails 58 .
- the conical member 62 of a fastener 60 can be first inserted into a lower rail 58 until the hexagonal member 64 is positioned in a way that allows the cooperating bore 46 of the picket 44 to thereafter become engaged therewith.
- Another fastener 60 can then be inserted into an upper rail 58 at a location designed to mate with the lower rail. These steps are repeated to prepare the lower rail having a set of pickets to be joined to the upper rail having a set of corresponding fasteners.
- the lower rail 58 having the attached pickets is then affixed to the upper rail by the fasteners already attached thereto by slidably engaging the hexagonal members of the affixed fasteners into the cooperating bores of the pickets.
- the fastener 60 can be shaped having a head 64 having a cross-section of a regular convex n-sided shape such as a pentagon, heptagon, octagon, etc. As described above, the head 64 is inserted into a cooperating opening 46 of the picket 44 and the conical member of the fastener 62 is then threadably inserted into a rail 58 .
- the fastener 102 includes a solid, or alternatively hollow tubular member 110 having a cylindrical shape.
- the fastener 102 is desirably fabricated of a uniform material for ease of fabrication. Exemplary materials include plastics, nylon, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane.

Abstract
Description
- This application claims the benefit of priority from U.S. Provisional Patent Application Serial No. 60/393,125 filed Jul. 3, 2002, the entirety of which is incorporated herein by reference.
- The invention is related to fasteners and methods used to assemble a railing, balustrade or fence. More specifically, the invention is concerned with a fastener that can be affixed to opposing ends of a picket or baluster in order to attach the picket to a pair of rails for assembly of a picket fence or balustrade.
- Picket fences are in widespread use to demarcate property lines and to enclose specific spaces within a property such as a patio, backyard deck, pool, and the like. Such fences incorporate a variety of designs but generally consist of a sequence of vertically aligned, elongate balustrades or pickets that are fastened perpendicularly to horizontal support members or rails with intervening spaces between any two pickets. An early version of the picket fence was comprised of flat rectangular pickets with pointed top ends attached to one side of upper and lower horizontal support members so that the pointed ends of the pickets were exposed and disposed above the upper horizontal member. This design and construction technique presented not only a pleasing, aesthetic appearance but also provided a functional characteristic as the top pointed ends of the pickets discouraged climbing over the fence.
- Another type of picket fence is comprised of elongate, rectangular pickets or balustrades that are attached at opposing ends thereof to upper and lower fence rails. With this type of fence, the upper fence rail is located over the top end of the pickets and functions as the uppermost surface or portion of the fence. The pickets are attached to the fence rails by various methods and devices. For instance, the ends of the pickets can be configured into a particular shape or design that is received into cooperating apertures or bores located in the fence rails, such as screw threads formed onto the ends of the pickets and around cooperating bores of the fence rails so that the pickets can be screwed into said fence rails. However, such method of attachment provides an inadequate means of affixing pickets to fence rails if the fence components are manufactured of certain materials that have limited load-bearing capabilities such as plastic or vinyl.
- The pickets can also be attached by fasteners such as nails or screws to the fence rails with said means of attachment strengthened as needed by the use of brackets and the like. This method of attachment presents less than a satisfactory appearance as nails and screws may be visible if not properly countersunk and if any brackets are not seated within a depression so that said fasteners and brackets are flush with the surface of the pickets and fence rails.
- What is needed then is the provision of a fastening means and a method of assembling picket fences that overcomes the aforementioned disadvantages of assembling picket fences. The subject of the instant invention presents a variety of fasteners that can be used for attaching pickets to upper and lower fence rails and a method for such assembly in order that a picket fence that is stable and secure can be erected using a variety of fence construction materials while also providing the fence with a pleasing and aesthetic appearance. Such fastening means is comprised of fasteners that are inserted at a first portion or end thereof into opposing ends of a picket and inserted at a second portion or end thereof into adjacent fence rails.
- Numerous designs for assembling picket fences have been provided in the prior art. Even though these designs may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of an aspect of the invention. Such designs are exemplified by U.S. Pat. No. 4,377,275, Railing Construction, issued to Faber et al. on 22 Mar. 1983; U.S. Pat. No. 4,625,948, Picket Fence, issued to Lustvee on 2 Dec. 1986; U.S. Pat. No. 4,968,005, Picket Attachment, issued to Zen on 6 Nov. 1990; U.S. Pat. No. 5,029,820, Wedge-Adjustable Base For Rail Posts and The Like, issued to Katz on 9 Jul. 1991; and U.S. Pat. No. 5,454,548, Modular Metal Fencing And Gratings Employing Novel Fastening Means For Reduction Of Assembly Time, issued to Moore on 3 Oct. 1995.
- As such, it may be appreciated that there is a continuing need for a new and improved fastening means and method of assembling picket fences that is comprised of fasteners that are inserted into or otherwise attached at a first portion or end thereof to opposing ends of a picket and inserted at a second portion or end thereof into adjacent fence rails so that a picket fence of various materials such as wood, metal, vinyl, and the like can be assembled quickly and efficiently and with a pleasing and aesthetic appearance. These aspects of the invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus that substantially fulfills this need. Additionally, the prior and commercial techniques do not suggest the present inventive combination of component elements arranged and configured as disclosed herein.
- An aspect of the invention, which will be described in greater detail hereinafter, relates to the field of fasteners and methods used to assemble fences. More specifically, this version of the invention is concerned with a fastener that can be affixed to opposing ends of a picket in order to attach said picket to adjacent fence rails for assembly of a picket fence.
- According to an aspect of the invention, a fastener is provided to affix a first article such as a picket to a second article such as a rail to form a railing or balustrade. The fastener includes a first engaging surface having a maximum diameter adapted to engage an interior surface of an opening in the first article and a mating surface adapted to mate with the second article. The first engaging surface can have shape selected from cylindrical, ellipsoidal, conical, elliptic conical frustum, pyramidal frustum, and ball and other shapes having cross-sections of rectangular, pentagonal, hexagonal, octagonal and other regular polygons having at least four sides such that good engagement is obtained and the fastener is hidden from view in the assembled railing.
- According to an aspect of the invention, a fastener is provided for affixing pickets to fence rails in order to construct a picket fence, the fastener including a cylindrical member and a rectangular member. The cylindrical member and rectangular member are connected at cooperating ends with the cylindrical member and rectangular member presenting opposing, exposed ends. Screw threads are located around the exterior of the cylindrical member, and a series of ridges or protrusion are located on sidewalls of the rectangular member. In a first alternative embodiment of the fastener, the cylindrical member is provided without screw threads. In a second alternate embodiment, the fastener is comprised of a conical member with screw threads surrounding the exterior thereof and a rectangular member connected to a wider end of the conical member. In a third alternative embodiment, the fastener is comprised of a conical member with surrounding screw threads and a hexagonal member connected to a wider end of the conical member.
- According to another aspect of the invention, a picket fence is assembled by inserting the rectangular or hexagonal member of a fastener into a bore formed into each end of a picket so that the ridges thereof frictionally engage the sidewalls of said bore and then inserting the cylindrical or conical member of the fasteners, which extend beyond the pickets, into cooperating bores of the fence rails. The pickets can be anchored to the fence rails by rotating said pickets so that the screw threads of the cylindrical or conical member engage the surrounding sidewall of cooperating bores in the fence rails.
- If necessary, the spacing of the pickets between the fence rails can be facilitated by use of a measuring guide releasably attached to the side of a container for storage and transport of the pickets. The measuring guide is comprised of two sidewalls that are perpendicularly attached with a series of apertures located in a sidewall thereof. The sidewall with said apertures located therein can be placed over two fence rails so that bores can be drilled into the fence rails using said apertures as a guide.
- Using the fasteners and the method described above, a picket fence that is stable and well constructed can be assembled quickly and efficiently. Fasteners are fabricated from exemplary materials including plastics, nylon, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane, or alternatively, nondeformable materials such as metals including, but not limited to aluminum, zinc, galvanized steel and stainless steel. The pickets and fence rails can be comprised of a variety of materials, such as wood, plastic, vinyl, various metals and the like.
- According to another aspect of the invention, a fastening means and method for assembling picket fence is provided in which a fastener includes a cylindrical or conical member and a rectangular or hexagonal member connected thereto. Screw threads or ridges surround the exterior of the cylindrical or conical member and ridges surround the rectangular or hexagonal member; and a plurality of pickets with bores formed into opposing ends thereof for receipt of individual fasteners.
- According to another aspect of the invention a fastening means and method is provided for assembling picket fence through use of fasteners that releasably attach pickets to upper and lower fence rails so that a picket fence that is stable and secure can be erected quickly and efficiently with a minimum amount of tools and expenditure of time and effort.

- Referring now to the drawings and, in particular, to FIG. 1 through FIG. 3 wherein there are illustrated a first embodiment of a
fastener 10 for assembling a picket fence. Thefastener 10 is a one-piece, unitary device that is comprised of acylindrical member 12 and arectangular member 14. Thecylindrical member 12 consists of afirst end 16 that is connected to therectangular member 14 and an opposedsecond end 18.Screw threads 20 surround thecylindrical member 12. Desirably,fasteners 10 are fabricated of two types:fasteners 10 havingscrew threads 20 which fasten in a clockwise direction, andfasteners 10 havingscrew threads 20 which fasten in a counterclockwise direction. The rectangular member is comprised of afirst end 22 that is connected to thecylindrical member 12 and a secondopposed end 24. A series ofparallel ridges 26 is located on the four sidewalls of therectangular member 14. Therectangular member 14 is desirably sized to fit an opening of a readily available picket 44 (FIG. 5) without requiring thepicket 44 to be specially manufactured. - Referring to FIG. 4, therein illustrated is a second embodiment of the
fastener 28. Thefastener 28 is comprised of acylindrical member 30 and arectangular member 32, saidcylindrical member 30 consisting of afirst end 34 connected to therectangular member 32 and a secondopposed end 36. Therectangular member 32 is comprised of afirst end 38 that is connected to thecylindrical member 30 and a secondopposed end 40.Parallel ridges 42 are located on the four sidewalls of therectangular member 32. - The
fasteners - As displayed in FIG. 5 a picket fence is being assembled with an elongate,
rectangular picket 44 havingrectangular bores 46 located at opposing ends thereof. Thepicket 44 is disposed between upper and lower fence rails 48.Bores 50 are located on facing sides of the fence rails 48. Thepicket 44 is disposed in perpendicular relation to the fence rails 48 with thebores 46 of thepicket 44 in alignment with cooperatingbores 50 of the fence rails 48. Afirst fastener 10 is located between the top end of thepicket 44 and anupper fence rail 48, and asecond fastener 10 is located between the bottom end of thepicket 44 and alower fence rail 48. Thecylindrical member 12 of eachfastener 10 is disposed toward a cooperating, cylindrical bore 50 of afence rail 48, and therectangular member 14 of eachfastener 10 is disposed toward a cooperating, rectangular bore 46 of thepicket 44. - Referring to FIG. 6, the
fasteners 10 are attached to thepicket 44 by means of therectangular members 44 of thefasteners 10 inserted into the rectangular bores 46 located at opposing ends of thepicket 10. Theridges 26 of therectangular member 44 frictionally engage the communicating sidewalls surrounding thebores 46 so that thefasteners 10 are securely anchored within thebores 46 to thepicket 44. Desirably,fasteners 10 having clockwise-fastening screw threads 20 are inserted intofirst bores 46 ofpickets 44 andfasteners 10 having counterclockwise-fastening screw threads 20 are inserted intosecond bores 46 ofpickets 44 on opposite ends of thepickets 44. In such manner, thepicket 44 with thefasteners 10 secured thereto can be attached to the fence rails 48 by inserting the exposedcylindrical members 12 of the fasteners into cooperating cylindrical bores 50 of the fence rails 48 and rotating thepicket 44 so that thescrew threads 20 of thecylindrical members 12 engage the sidewalls of thebores 50 as illustrated in FIG. 7. Preparing thepicket 44 by insertingfasteners 10 of clockwise and counterclockwise fastening types in respective opposite ends thereof assures that thefasteners 10 engage the upper rail and lower rail at the same time by the same rotational movement to secure the pickets to the rail. - As displayed in FIG. 8, a plurality of
pickets 44 can be aligned for attachment to upper and lower fence rails 48 to construct a picket fence of varying length and secured to saidrails 48 as described previously. Thepickets 44 and the fence rails 48 are comprised of material that is lightweight, durable, rigid, and resistant to corrosion and oxidation, such as various wood products, metals and alloys, plastic, vinyl, composite materials, and the like. - A third embodiment of a
fastener 52 is illustrated in FIG. 9 as having aconical member 54 with surrounding screw threads, saidconical member 54 tapering from a narrower end to a wider end with said wider end connected to arectangular member 56. Thefastener 52 is aligned between an end of apicket 44 with cooperatingbore 46 and a communicating side of afence rail 58. Two types offasteners 52 are desirably provided, a first in which theconical member 54 has clockwise-fastening threads, and a second in which theconical member 54 has counterclockwise-fastening threads. - The
picket 44 is attached to upper andlower rails 58 by first inserting therectangular member 56 of thefastener 52 into thebore 46 at opposed ends of thepicket 44 so that therectangular member 56 frictionally engages the surrounding sidewalls of thebore 46 and anchors thefastener 52 to thepicket 44. Thepicket 44 with thefastener 52 disposed therein is placed adjacent to therails 58 in perpendicular relation and rotated while pressing theconical members 54 of thefasteners 52 against therails 58 until theconical members 54 engage therails 58, initially securing thefasteners 52 andpicket 44 to said rails 58. Thefasteners 52 are then screwed into therails 58 until theconical members 54 are completely disposed within therails 58. Desirably, a clockwise-threadedfastener 52 is attached to one end of the picket and a counterclockwise-threadedfastener 52 is attached to the other, such that rotating thepicket 44 in one direction engages both of therails 58 at the same time to secure thepicket 44 to therails 58. Theconical members 54 of thefasteners 52 can be attached to therails 58 with or without a pilot hole formed in said rails 58. It may also be desirable under limited circumstances to further secure therectangular member 56 of thefastener 52 to thepicket 44 by inserting a screw 55 through a sidewall of thebore 46 of thepicket 44, for example. - Referring to FIG. 10 a fourth embodiment of the
fastener 60 is illustrated. Thefastener 60 is comprised of aconical member 62 with surrounding screw threads. Theconical member 62 tapers from a narrower end to a wider end with said wider end connected to ahexagonal member 64. Two types offasteners 60 are desirably provided, a first in which theconical member 62 has clockwise-fastening threads, and a second in which theconical member 62 has counterclockwise-fastening threads. - The
fasteners 60 are attached to each end thepicket 44 by inserting thehexagonal members 64 into thebores 46 at opposed ends of thepicket 44 until the sidewalls of thehexagonal members 64 engage cooperating sidewalls of thebores 46, and the conical members extend above the end of thepicket 44. Desirably, a clockwise-threadedfastener 60 is attached to one end of the picket and a counterclockwise-threadedfastener 60 is attached to the other. Thepicket 44 having afastener 60 secured at each end thereof is aligned between upper andlower rails 58 so that theconical members 62 of thefasteners 60 engage therails 58, initially securing thefasteners 60 andpicket 44 to said rails 58. Thefasteners 60 are then screwed into therails 58 by pressing theconical members 62 against therails 58 and rotating thepicket 44 until theconical members 62 are completely disposed within therails 58. Theconical members 62 of thefasteners 60 can be attached to therails 58 with or without a pilot hole formed in said rails 58. - Alternatively, the
conical member 62 of afastener 60 can be first inserted into alower rail 58 until thehexagonal member 64 is positioned in a way that allows the cooperating bore 46 of thepicket 44 to thereafter become engaged therewith. Anotherfastener 60 can then be inserted into anupper rail 58 at a location designed to mate with the lower rail. These steps are repeated to prepare the lower rail having a set of pickets to be joined to the upper rail having a set of corresponding fasteners. Thelower rail 58 having the attached pickets is then affixed to the upper rail by the fasteners already attached thereto by slidably engaging the hexagonal members of the affixed fasteners into the cooperating bores of the pickets. - In an alternative embodiment, the
fastener 60 can be shaped having ahead 64 having a cross-section of a regular convex n-sided shape such as a pentagon, heptagon, octagon, etc. As described above, thehead 64 is inserted into a cooperatingopening 46 of thepicket 44 and the conical member of thefastener 62 is then threadably inserted into arail 58. - A fifth embodiment of a fastener is illustrated in FIG. 11. As shown in FIG. 11, the
fastener 102 includes a solid, or alternatively hollowtubular member 110 having a cylindrical shape. Thefastener 102 is desirably fabricated of a uniform material for ease of fabrication. Exemplary materials include plastics, nylon, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane. Themember 110 includes a first set ofridges 112 disposed on an exterior surface of afirst portion 111 thereof, for use in frictionally engaging an interior surface of a cylindrical opening provided in a longitudinal end of a picket or baluster. The maximum dimensions of the ridges of thefastener 102 are preferably selected to be slightly larger than the internal dimensions of the opening in the picket, e.g. by an amount on the order of hundredths of an inch alongdiameters 114 of the ridges, such that the ridges frictionally engage the interior surface of the opening in the picket and stay engaged despite stresses that the assembled rail and picket may encounter later. In such case, the ridges and/or thecylindrical member 112 are fabricated of a material and thickness such that some deformation of the ridges and/or thecylindrical member 112 occurs upon inserting thefastener 100 into the opening of the picket. - The
fastener 100 is also provided with asecond portion 116 having a second set ofridges 113 used to frictionally engage an interior surface of an opening in another member to which the picket is joined, for example, a rail of a railing. As the opening in the rail to be joined to the picket may be of a smaller or larger size than the opening in the picket, either the diameter of thecylindrical member 115, theridges 113, or both may be varied for thatportion 116 of thefastener 100 that is intended to be inserted into the opening of the rail. When thefirst portion 111 and thesecond portion 116 have the same diameter, astop 118 is preferably provided on the exterior surface of themember 110 between the first andsecond portions fastener 102 is desirably fabricated in one piece and of uniform material throughout, the first andsecond portions - A sixth embodiment of a fastener is illustrated in FIG. 12. As shown in FIG. 12, the
fastener 102 includes a solid, or alternatively hollowtubular member 120 having a cylindrical shape. Thefastener 102 is desirably fabricated of a uniform material for ease of fabrication. Exemplary materials include plastics, nylon, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane and nondeformable materials such as metals including, but not limited to aluminum, zinc, galvanized steel and stainless steel. - As distinguished from
fastener 100 shown in FIG. 11,fastener 102 includes a first set ofthreads 121 in afirst portion 122, and a second set ofthreads 123 in asecond portion 124 thereof. As in thefastener 100 described above, thefirst portion 122 andsecond portion 124 may have different diameters. In addition, the first andsecond portions fastener 102 can be threaded into a rail and thereafter threaded into the picket by rotating the picket onto the fastener. Alternatively, thefastener 102 can be threaded into a picket and thereafter threaded into the rail by rotating the picket with the attached fastener into the rail. When thefastener 102 is thus dual threaded, i.e. having both clockwise-fastening and counterclockwise-fastening threads, threading the fastener into the second of the picket or rail will not loosen, but rather only serve to further tighten the fastener into rail or picket into which it has already been screwed. In between thefirst portion 122 and the second portion 124 astop 126 is preferably placed such that thefastener 102 is not inserted too deeply into either the picket or the rail. In such manner, thefirst portion 122 is screwed a desirable depth into the picket and asecond portion 124 is screwed a desirable depth into the rail. - While the
fastener 102 is desirably fabricated in one piece and of uniform material throughout, the first andsecond portions fastener 102 may be constructed of different materials or different pieces of the same or similar materials and then assembled to make the fastener. For example, it may be desirable to form afirst portion 122 of thefastener 102 of a deformable material such as plastic, nylon, polyurethane, etc., for insertion of thefirst portion 122 into an opening in a picket of hollow tubular construction, e.g. of metal, plastic, polyvinyl chloride or composite material. Asecond portion 124 of thefastener 102 may desirably be formed of a different material such as solid steel, aluminum, galvanized steel, zinc, etc. for providing a strong, nondeformable surface for screwing thefastener 102 into a smaller opening in a rail, for example. - The
fastener 102 is preferably provided with anaperture 128 on at least one end thereof, the aperture preferably being sized and shaped to accommodate standard-sized tools such as those of rectangular cross-section, e.g. a rectangular nut driver or socket wrench, or those having other cross-sections, e.g. hexagonal drivers, also known as “Allen” wrenches, for example. Alternatively, to facilitate turning of the fastener, at least one end of thefastener 102 may be provided with abolthead 130, which is desirably formed integrally to a surface which spans thecylindrical member 120. Although the bolthead is shown protruding from the end of thecylindrical member 120, it can be joined to a surface that is recessed from the end of thecylindrical member 120. - As not all pickets have a cylindrical shape or are otherwise amenable to fastening by cylindrically shaped fasteners, FIGS. 13 and 14 illustrate sixth and seventh embodiments of fasteners of the invention which are intended to be applied to the joining of a picket to a rail when openings are of different shapes. As shown in the perspective drawing of FIG. 13A and the top (plan) view thereof in FIG. 13B, a
fastener 135 is provided having afirst portion 136 and asecond portion 138, each one being in the shape of an elliptic conical frustum. Conical frustums have sidewalls 141 that are curved surfaces of revolution about an axis. A conical frustum is best suited for mating with an opening that also has a curved surface. As described above relative to FIG. 11, the first and second portions of thefastener 135 are desirably provided with sets ofridges stop 140 is also preferably provided such that thefastener 135 is not inserted too deeply into either the rail or the picket. - The seventh embodiment of a
fastener 145, illustrated in a perspective view in FIG. 14A and in a top (plan) view in FIG. 14B, varies from the sixth embodiment in that the shape of each of thefirst portion 146 and thesecond portion 148 is a pyramidal frustum rather than a conical frustum. As such,fastener 145 includessides fastener 135 described above relative to FIGS. 13A-13B. Thepyramidal fastener 145 is more preferably employed where the opening of the picket or rail has at least some straight sides for which a straight-sided fastener 145 provides a better fit. As described above relative to FIGS. 13A-13B, the first and second portions of thefastener 145 are desirably provided with sets ofridges stop 152 is also preferably provided such that thefastener 145 is not inserted too deeply into either the rail or the picket. - FIG. 15 illustrates an eighth embodiment of a
fastener 200 according to the invention. One difference betweenfastener 200 and those shown and described above is that the fastener is substantially in the shape of a ball. By “ball” is meant those classes of shapes that are convex and generally round in shape and may be made up of one or more curved surfaces and/or include surfaces which are planar. Thus, as defined herein, “ball” includes but is not limited to the following shapes: sphere (FIG. 15), prolate spheroid (FIG. 16), oblate spheroid (FIG. 17), regular convex polyhedra where the base polygon is at least a pentagon, i.e. a dodecahedron (FIG. 18C), icosahedron (FIG. 18A), and any other shapes, e.g. geodesic domes, that approximate a sphere (such as the shapes shown in FIGS. 18B, and 18D-18F), or approximate the shapes of prolate spheroid or oblate spheroid. - As shown in FIG. 15, the
fastener 200 is a solid, or alternatively, hollow member having a ball shape. Desirably, atop surface 218 and an oppositebottom surface 220 are substantially flat, to facilitate ease of placement and assembly onto a facing surface of an item, e.g. a rail. Thefastener 200 is desirably fabricated as a single piece of a uniform material for ease of fabrication. Exemplary materials include nylon, plastics, polyvinyl chloride, and other deformable materials including but not limited to synthetic rubber and polyurethane. Thefastener 200 preferably includes a first set ofridges 211 disposed on an exterior surface of afirst portion 212 thereof, for use in frictionally engaging an interior surface of a cylindrical opening provided in a longitudinal end of a picket or baluster. The maximum dimensions of the ridges of thefastener 200 are preferably selected to be slightly larger than the internal dimensions of the opening in the picket, e.g. by an amount on the order of hundredths of an inch along the diameter of the ridges, such that the ridges frictionally engage the interior surface of the opening in the picket and stay engaged despite stresses that the assembled rail and picket may encounter later. In such case, thefastener 200 and/or theridges 211 are fabricated of a material and thickness such that some deformation of the ridges and/or the underlying ball occurs upon inserting thefastener 200 into the opening of the picket. - The
fastener 200 is also provided with asecond portion 214 having a second set ofridges 213 used to frictionally engage an interior surface of an opening in another member to which the picket is joined, for example, a rail of a railing. Theridges 213 of the second set are desirably slanted in the opposite direction from theridges 211 of the first set such that theridges 213 frictionally engage a first opening in one item, e.g. a rail, whileridges 211 frictionally engage an opening in another item, e.g. a picket. - A
stop 222 may be provided on the exterior surface of thefastener 200 between the first andsecond portions fastener 200 is desirably fabricated in one piece and of uniform material throughout, the first andsecond portions fastener 200 may be constructed of different materials or different pieces of the same or similar materials and then assembled to make the fastener. - The
fastener 200 is preferably provided with anaperture 216 on at least one end thereof, the aperture preferably being sized and shaped to accommodate standard-sized tools such as those of rectangular cross-section, e.g. a rectangular nut driver or socket wrench, or those having other cross-sections, e.g. hexagonal drivers, also known as “Allen” wrenches, for example. In such case, theaperture 216 provides a way of applying torque to insert alower portion 214 of thefastener 200 into an item such as a rail. - Alternatively, the
aperture 216 may be a countersink for retaining a screw or bolt of length sufficient to pass through thefastener 200 from the side of theaperture 216 to the opposite side, the screw or bolt then threadably engaging another item, e.g. the rail thereunder. - Alternatively, to facilitate turning of the fastener, at least one end of the
fastener 200 may be provided with a bolthead (such as that shown and described above relative to FIG. 12) in the place ofaperture 216, the bolthead being desirably formed integrally to atop surface 218 of thefastener 200. In such case, the bolthead provides a way of applying torque to insert alower portion 214 of thefastener 200 into an item such as a rail. - In a preferred method of assembling a picket to a rail to form an element of a railing or balustrade, the
fastener 200 is placed,bottom side 220 down on a rail, leaving thetop surface 218 exposed. The body of a screw or bolt is threadably inserted into or, alternatively, passed through thefastener 200 to threadably engage the rail below, while the screwhead, bolthead, or tool-receiving aperture of thefastener 200 remains accessible from atop surface 218 to allow torque to be applied to affix the fastener to the rail. Thereafter, a cooperating opening of the picket is then inserted over thefastener 200 to affix the picket to the rail. The cooperating opening can have a variety of shapes such as cylindrical, conical, rectangular, hexagonal or other regular polygon, as well as in the shape of a half-ball or section of a ball, as that term is defined herein. - To continue making a balustrade, the process is then repeated by affixing
fasteners 200 at desired spacings, and affixing pickets thereto to make an assembly having a rail and a plurality of pickets affixed thereto. This represents a “lower” rail of the balustrade, for example. Then,fasteners 200 are affixed to a second rail at desired spacings. The balustrade is then completed by mating the pickets that are affixed to the lower rail to thefasteners 200 that are affixed to the second, upper rail. - While in many railings or balustrades the pickets or balusters are oriented at right angles, many occasions arise when pickets must be oriented at other than right angles, e.g. stairways, in which case at least one of the angles that the baluster makes relative to the rail is acute. The ball-shape of
fasteners 200 makes them well-suited for this purpose because the angle that each ball-shapedfastener 200 makes relative to the opening in a picket can change while the fastener still continues to frictionally engage the opening. - FIGS. 16, 17 and18A through 18F illustrate alternative ball shapes to which
fasteners 200 may be constructed in preferred embodiments, bearing in mind, that in each case, a top surface and a bottom surface of the shape are preferably opposing parallel planes, for ease of assembly of the rail to picket. - A
container 66 for storing and transportingpickets 44 is illustrated in FIG. 19. Thecontainer 66 is equipped with ahole measuring guide 68 that can be attached to thecontainer 66 by various means, such as perforation, VELCRO®, adhesion, and the like. Thehold measuring guide 68 is comprised of afirst sidewall 70 and asecond sidewall 72, said sidewalls 70, 72 disposed in perpendicular relation to each other. A plurality ofapertures 74 is located in thesecond sidewall 72 thereof. Theapertures 74 are positioned so as to coincide with the proper or intended spacing or positioning of bores within the fence rails 48, 58. As such, thehole measuring guide 68 can be positioned over two adjacent fence rails 48 as shown in FIG. 20 so that apertures or bores can be placed within said fence rails 48 in precise locations thereon by drilling, routing or similar processes.
