Description
BACKGROUND OF THE INVENTION

The present invention relates to a fence system wherein a horizontal fence rail is attached to a vertical fence post via a horizontal rail support.


1. Field of the Invention


The present invention relates generally to a fence system and a method of assembling a fence system, and, more particularly, to such a fence system that includes horizontal rail supports inserted into a fence post for supporting horizontal rails. The fence post is configured so it can be used for either straight run fence sections or corners.


2. Description of the Related Art


Fence systems are known in the industry. Known fence systems are difficult to assemble, except by skilled workers, or else are aesthetically unpleasing. In many systems, a horizontal rail must be attached to a fence post by a user in a process which requires the user to take measurements to attach brackets, resulting in a fence system with exposed and unsightly brackets. Another system, wherein inserts rather than exposed brackets are utilized as a means of connection, the connection is proportioned so as to allow expansion and contraction of the rail, resulting in instability.


SUMMARY OF THE INVENTION

The present invention provides a fence post that may include apertures so that a fence system may be assembled easily, and be aesthetically pleasing, with horizontal rails held in place by horizontal rail supports inserted into the fence posts, rather than through the use of brackets.


The horizontal rail supports inserted into the fence post preferably are locked in place with locking devices for additional stability. These locking devices may be wedges.


The horizontal rail supports which are inserted into the fence post may include projecting tabs received in concave slots in the wedges.


The present invention further provides a method of assembling a fence wherein horizontal rails are held in place by horizontal rail supports inserted into apertures in fence posts.


The method may include a locking step by inserting wedges between the horizontal rail supports and the apertures in the fence post.


The horizontal rail supports preferably are inserted from an interior of the fence post.


Both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.


The accompanying drawings are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and together with the description serve to explain the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings, and in particular to FIGS. 1 and 2, a fence post in accordance with the present invention is referred to generally by reference numeral 1. The fence post 1 comprises an inner structural vertical post 2. The inner structural vertical post 2 defines a vertical axis a-a, and includes an upper distal end 4 and a lower distal end 6. The lower distal end 6 comprises a base flange 8 through which the inner structural vertical post 2 is configured to be attached to a generally horizontal surface, e.g. a deck or patio.


The fence post 1 can be secured to the surface by the base flange 8. In the preferred embodiment, carriage bolts and lag bolts insert through the base flange 8 and into the surface to connect the inner structural vertical post 2 to reinforcements 14. An alternative embodiment includes a bolt-on addition that may be used for side mounting and mounting to stringers on stairs.


A lower insert block 16, as shown in FIGS. 1 and 3, having a coaxial bore 18 slides over the inner structural vertical post 2 and rests on top of the base flange 8.


An outer post 20 comprises a coaxial bore 22, an upper distal opening 24, and a lower distal opening 26. The upper and lower distal openings 24, 26 are dimensioned to slide over the inner structural vertical post 2 and the lower insert block 16. The outer post 20 also includes an upper aperture 28 proximate the upper distal opening 24 and a lower aperture 30. The lower aperture 30 is positioned at a selected height h1 above the lower distal opening 26, and the selected height h1 is substantially equal to the height of the lower insert block 16. Preferably, the outer post 20 is composed of galvanized and powder coated steel, however, other material may be utilized depending on an intended use of the fence and characteristics required for the fence post 1.


As broadly depicted in FIGS. 2, 3 and 4, a first horizontal rail support 32 is inserted in to a lower aperture 30 at a direction substantially normal to the vertical axis a-a. A second horizontal rail support 34 is inserted into an upper aperture 28 at a direction substantially normal to the vertical axis a-a. A first portion 36, 38 of the first and second horizontal rail supports 32, 34 extend from the exterior 40 of the outer post 20 and a second portion 42, 44 of the first and second horizontal rail supports, 32, 34 extend into the interior 46 of the outer post 20.


As broadly depicted in FIG. 6, an upper insert block 48 applies downward compressive pressure to the second portion 44 of the second horizontal rail support 34. As broadly depicted in FIG. 3, the lower insert block 16 applies upward compressive pressure to the second portion 42 of the first horizontal rail support 32. In a preferred embodiment, both the first and second horizontal rail supports 32, 34 comprise flanges.


As broadly depicted in FIGS. 8a and 8b, the first and second horizontal rail supports 32, 34 are further locked in place with upper and lower locking devices 50 inserted through the respective upper and lower apertures 28, 30. As broadly embodied herein, these locking devices 50 preferably comprise wedges 52 configured to fit on sides of the respective horizontal rail supports 32, 34. Each wedge 52 has an inner sloped surface, having an angle α, in contact with a corresponding sloped outer surface of the respective horizontal rail support 32, 34, having an angle β, wherein angles α and β are substantially supplementary. Preferably, the horizontal rail supports 32, 34 include projecting tabs 54, 56 and the inner surfaces of the wedges 52 include concave slots 58 configured to receive the projecting tabs 53, 54. Preferably, the wedges 52 further comprise stops 60, which when engaged are in contact with the respective horizontal rail supports 32, 34.


Preferably, as shown in FIG. 2, decorative caps 62 are inserted into any lower apertures 30 and upper apertures 28 in which no horizontal rail supports are inserted.


As illustrated in FIG. 9, two fence posts can be connected to each other with a lower horizontal rail 64 and upper horizontal rail 66 to create a fence system 68. The lower and upper horizontal rails 64, 66 have open ends which are inserted over each fence post's upper and lower horizontal rail supports 32, 34, respectively, as shown in FIGS. 3-8. In a preferred embodiment, the locking device 50, preferably the wedge 52, is in contact with the horizontal rail supports 32, 34, thus holding the horizontal rails 64, 66 in place. In another embodiment, the lower and upper horizontal rails 64, 66 include an opening for the insertion of the locking device 50.


Accent rails, as shown in FIGS. 10a-10f can be attached to the lower and upper horizontal rails 64, 66. FIGS. 10a-f illustrate various options for accent rails for the upper horizontal rail 66, including no accent rail (FIG. 10a), white vinyl (FIG. 10b), steel powder coated (FIG. 10c), shaped PT wood (FIG. 10d), shaped composite (FIG. 10e), and as well as a nylon accent for the lower horizontal rail 64 (FIG. 10f).


The process of assembling the fence system 68 is designed to be simple and to result in aesthetically pleasing connections. The process for assembling the fence system preferably will be performed in the following sequence of steps, but the invention is not limited to this sequence.


In the preferred embodiment, the fence system 68 can be assembled by attaching the inner structural post 2 to a substantially horizontal surface, for example a deck. This step is repeated as necessary until the desired final fence configuration is achieved, by using each fence post 1 as an end, corner, or straight run fence section. Referring to FIG. 3 the inner structural vertical post 2 is inserted into the coaxial bore 3 of the lower insert block 16 with the lower insert block 16 moving over and around the inner structural vertical post 2 until it is in contact with a substantially horizontal surface or, as in the preferred embodiment, with the base flange 8.


Referring to FIGS. 4, 5 and 8b, the first and second horizontal rail supports 32, 34 are inserted though the lower and upper apertures 30, 28, respectively. In a preferred embodiment of this invention, the first and second horizontal rail supports are inserted from the interior 46 of the outer post 20 to the exterior 40 of the outer post 20. The outer post 20 slides over and around the inner structural vertical post 2 and the lower insert block 16, so that the inner structural vertical post 2 extends upward within the bore 26 of the outer post 20 and the lower insert block 16 applies an upward compressive force to the second portion 42 of the first horizontal rail support 32. FIG. 6 shows the upper insert block 48 inserted into the upper distal opening 24 of the outer post 20 until it contacts and applies a downward compressive force to the second portion 44 of the second horizontal rail support 34. The open ends of the lower and upper horizontal rails 64, 66 slide onto the first and second horizontal rail supports 32, 34, respectively.


Another step of the assembly process is locking the upper and lower horizontal rail supports 32, 34 in place against the upper and lower horizontal rails 66, 64. In one embodiment, this locking step comprises inserting a locking device 50, or specifically a wedge 52, between an inner wall of each of the lower and upper horizontal rails 64, 66 and an outer wall of the corresponding horizontal rail support 32, 34. This is further illustrated in FIGS. 7 and 8a.


A post cap 70 can be inserted into the upper distal opening 24 of the outer post 20. As illustrated in FIGS. 11a-b, accent post caps including a pyramid with a ball 72 and a flat top 74 post caps have lower distal openings that slide over the post cap 70. The accent post caps 72, 74 are held into place with interior teeth 76.


Having thus described the fence system of the present invention, and method of assembly thereof, with particular reference to the preferred embodiments, it will be apparent to persons of ordinary skill in the art that various changes and modifications can be made therein without departing from the spirit and scope of the present invention, which is defined by the appended claims and their legal equivalents.
