Description

BACKGROUND OF THE INVENTION

1. The Field of the Invention

The present invention relates generally to modular fence systems. More particularly, it concerns a modular fence plank that is lockably insertable into an channel of a fence rail.

2. The Background Art

Modular fence systems are becoming increasingly popular with home owners and businesses alike. Vinyl polymeric fence components have been designed for use in assembling an attractive fence.

The prior art modular fence systems are characterized by a number of disadvantages. Some systems require the laborious and time consuming practice of fastening the fence components with nuts and bolts or other fastening devices. Some of the more decorative-oriented fence systems utilize a lower fence rail to support substantially the entire weight of the planks of the fence, a design that requires a higher frequency of intermittent support posts to inhibit sagging in the lower fence rail.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a fence system that is simple in design and easier to assemble.

It is another object of the invention to provide such a fence system that provides more support to fence planks of the system and thereby requires fewer intermittent support posts.

It is a further object of the invention to provide such a fence system having fence planks that are lockably insertable into supporting fence rails.

The above objects and others not specifically recited are realized in a specific illustrative embodiment of a modular fence system. The system includes fence planks designed for insertion into open channels of upper and lower fence rails. The fence rails are supported in a horizontal orientation between intermittent fence posts, with the fence planks extending vertically between the rails. The planks include resilient protrusions at their upper ends. The protrusions of the planks are designed to fit into internal passages formed in the open channels of the upper fence rail, into engagement with ledges defining the passages, to inhibit inadvertent removal of the planks from the upper rail.

Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the invention without undue experimentation. The objects and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF PRESENTLY PREFERRED EMBODIMENTS

For the purposes of promoting an understanding of the principles in accordance with the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the illustrated apparatus, and any additional applications of the principles of the invention as illustrated herein, which would normally occur to one skilled in the relevant art and possessed of this disclosure, are to be considered within the scope of the invention claimed.

Applicant has discovered that a modular fence system can be designed that is easier to assemble, and requires a lower frequency of intermittent support posts. Applicant's inventive combinations as disclosed herein provide a fence system that requires less time to install, but is structurally sound and aesthetically pleasing.

Referring now to FIGS. 1-3, there is shown a fence system designated generally at 10 in FIG. 1. The fence system 10 includes upper and lower fence rails 12 and 14 coupled to intermittent fence posts 16. A plurality of fence planks 18 are supported between the upper and lower fence rails 12 and 14. The upper fence rail 12 is thus configured to be supported in a laterally extending, elevated orientation.

The upper fence rail 12 comprises a first side 20 and an opposing second side 22. A first interior side wall 24 and an opposing second interior sidewall 26 define an open channel 28 therebetween. The upper fence rail 12 includes ledges 30 protruding outwardly from the first and second interior sidewalls 24 and 26, respectively, for supporting the fence planks 18 thereon. Each ledge 30 defines a passage 32. The ledges 30 may also be referred to as channel-projections.

Each plank 18 preferably includes a first exterior end section 34 configured for inserting into the open channel 28 of the upper fence rail 12. Protrusions 36 are preferably formed in the planks 18 and extend outwardly from opposing sides of the first exterior end section 34 for protruding into the passages 32 defined by the ledges 30 on the first and second interior sidewalls 24 and 26, respectively. The protrusions 36 thereby engage against the protruding ledges 30 to inhibit inadvertent removal of the planks 18 from the upper fence rail 12. The protrusions 36 may also be referred to as plank-projections.

In this manner, the upper fence rail 12 provides structural support for the fence planks 18. The planks 18 are thus supported by both the upper and lower fence rails 12 and 14, as opposed to prior art fence systems wherein only the lower fence rail supports the planks. The fence posts 16 are spaced close enough together to inhibit substantially sagging of the lower fence rail 14. Since the fence system 10 distributes the weight of the planks 18 between both the upper rail 12 and the lower rail 14, the frequency of the fence posts 16 is less and thus fewer fence posts 16 are required, resulting in a saving of material cost and labor of installation.

Each fence plank 18 further includes a second end section 38 opposite the first end section 34. The lower fence rail 14 also has an open channel 40 formed therein for receiving the second end sections 38 of the planks 18 thereinto. The lower fence rail 14 is preferably identical to the upper fence rail 12 in design, and includes the ledges and passages, as shown in FIG. 2. Alternatively, the lower fence rail may comprise a rail 14a as in FIG. 4, defining a smooth open channel 40a and an absence of the internal ledges and passages.

The ledges 30 preferably comprise first and second arrays of elongate ledges extending lengthwise along the first and second interior sidewalls 24 and 26, respectively, to enable selective engagement of the protrusions 36 of the fence planks 18 against the ledges 32 of the first and second arrays, respectively. Preferably, each array of elongate ledges 30 comprises at least two ledges disposed in substantial parallel orientation as shown. The ledges 30 of the first and second arrays are equal in number to define pairs of ledges, each pair comprising a ledge from the first array and a ledge from the second array, such that the ledges in each pair are substantially parallel and reside common to a single plane extending substantially perpendicular to the sides 20 and 22 of the rail 12.

The upper fence rail 12 and the sidewalls 20, 22 and ledges 30 thereof preferably comprise a one-piece, unitary member made of a resilient material having elastic memory, such as vinyl. The protrusions 36 of the planks 18 also preferably comprise a resilient material having elastic memory. The feature of resilient material having elastic memory operates to permit a locking engagement of the protrusions 36 into the passages 32. The protrusions 36 can be "snapped" into place into the passages 32.

Referring more particularly to FIG. 3, the fence planks 18 are hollow, each plank having a front wall 50, an opposing rear wall 52, and a left sidewall 54 and a right sidewall 56 coupled between the front and rear walls 50 and 52 at opposing sides thereof, respectively. A plurality of internal bracing walls 58 are disposed between the rear wall 52 and the front wall 50. The left sidewalls 54 have an elongate channel 60 formed therein, and the right sidewalls 56 have an elongate projection 62 formed thereon configured and dimensioned to be inserted into the channel 60 of the left sidewalls 54 of adjacent planks 18 for additional support.

The front and rear walls 50 and 52 of each plank 18 include an exterior surface 66 and an interior surface 68, and preferably an elongate groove 70 is formed in each of said front and rear walls extending lengthwise along the plank 18. The elongate grooves 70 in the front and rear walls comprise a crease in said front and rear walls, defined by a furrow 72 formed in the exterior surface 66, and an opposing ridge 74 formed in the interior surface 68. The grooves 70 are optional, and the front and rear walls 50 and 52 may alternatively comprise substantially planer walls characterized by an absence of grooves or other nonplaner structure.

The grooves 70 define a kind of "V" shape as shown in FIG. 3. This structural variation provides increased strength to the front and rear walls 50 and 52, to inhibit buckling and bending. The "V" grooves 70 further provide an enhanced aesthetic appeal to the planks 18. The planks 18 preferably comprise a cross section of one inch by 8 inches, and the "V" grooves 70 produce the appearance four inch planks even though the planks are eight inches wide in reality.

Regarding the protrusions 36, the front and rear walls 66 and 68 of the planks 18 each include an opening 80 formed in the first end section 34 of the plank 18, such that a circumferential edge 82 defines said opening 80. The protrusions 36 extend outwardly from a portion of said circumferential edges 82. Most preferably, the protrusions 36 each comprise a severed portion of the walls 50 and 52 of the planks 18, whereby the protrusions 36 are simply cut apart from the front and rear walls 50 and 52 to form the openings 80, and the protrusions 36 are crimped into an outwardly extending orientation.

It is to be understood that one aspect of the present invention contemplates the plank 18 as in FIG. 3 without the protrusions 36 formed thereon. The upper and lower fence rails could simply function as retaining channels, such that no part of the plank extends into the passages 32 in a locking relationship against the ledges 30.

The fence system 10 can be assembled in any suitable manner. Referring now to FIG. 5, a preferred method of assembling a fence comprises the steps of:

(a) coupling a first end 90 of an upper fence rail 12 and a first end 92 of a lower fence rail 14 to a fence post 16, and maintaining an opposing second end 95 of the upper fence rail 12 in an elevated orientation with relative to the first end 90 of said upper fence rail 12; (b) placing a lower end 19 of a first fence plank 18a into an open channel 40 of the lower fence rail 14, and an opposing upper end 21 of said first fence plank 18a into an open channel 28 of the upper fence rail 12; (c) placing a lower end 19b of a following fence plank 18b into the open channel 40 of the lower fence rail 14 and sliding said following fence plank 18b toward the first fence plank 18a (as illustrated by arrow A); (d) gradually lowering the second end 95 of the upper fence rail 12 (as illustrated by arrow B) such that an upper end 21b of the following fence plank 18b becomes received into the open channel 28 of the upper fence rail 12; (e) repeating steps (c) and (d) as many times as desired to thereby situate an array of fence planks 18 into position between the upper and lower fence rails 12 and 14.

The method set forth immediately above may be further augmented, wherein step (b) further comprises placing a protrusion 36 of the first fence plank 18a into an internal passage 32 (see FIG. 2) 28 of the upper fence rail 12 and into engagement with a ledge 30 defining the passage, and wherein step (d) further comprises placing a protrusion 36 of the following fence plank 18b into an internal passage 32 of the upper fence rail 12 and into engagement with a ledge 30 defining said internal passage.

Referring now to FIG. 6, a further method of assembling a fence comprises the steps of:

(a) coupling a first end 92 of a lower fence rail 14 to a support post 16; (b) placing lower ends 19 of a plurality of fence planks 18 into an open channel 40 of the lower fence rail 14; and (c) sliding an upper fence rail 12 onto upper ends 21 of the plurality of fence planks 18 (illustrated by arrow C) such that said upper ends 21 of the planks 18 reside in an open channel 28 of the upper fence rail 12 with protrusions 36 on said upper ends 21 extending into an internal passage 32 (shown in FIG. 2) of the upper fence rail 12 and into engagement with a ledge 30 (shown in FIG. 2) defining said internal passage.

The method set forth immediately above may be further augmented, wherein step (c) further comprises sliding the upper fence rail 12 sequentially along the upper ends 21 of the plurality of fence planks 18.

It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements.
