Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to sound barrier walls and more specifically it relates to a sound barrier wall system for reducing the transmission of noise into residential and commercially sensitive areas. The sound barrier wall system may also be used as a building layer to reduce the transmission of noise into a structure.

2. Description of the Prior Art

Sound barrier walls have been in use for years. Typically, a sound barrier wall is constructed of a solid wall structure along a road, railroad, commuter rail, airports and other noisy and traveled pathways. The sound barrier wall may be comprised of wood, concrete, plastic, composite materials and other types of materials capable of deflecting and/or absorbing various sound frequencies (low to high frequencies). The conventional sound barrier wall is typically constructed similar to a building structure and therefore requires a significant amount of time and money to adequately construct.

The main problem with conventional sound barrier walls is that they are expensive to construct. Another problem with conventional sound barrier walls is that they require a significant amount of time and planning to construct. A further problem with conventional sound barrier walls is that they are relatively complex and difficult to construct.

Examples of patented sound barrier walls which are illustrative of such prior art include U.S. Pat. No. 4,707,962 to Meheen; U.S. Pat. No. 5,324,469 to Walter; U.S. Pat. No. 5,539,163 to Anderson; U.S. Pat. No. 4,278,146 to Lerner; U.S. Pat. No. 6,016,887 to Underhill.

While these devices may be suitable for the particular purpose to which they address, they are not as suitable for reducing the transmission of noise into residential and commercially sensitive areas. Conventional sound barrier walls are inefficient in deflecting and absorbing sound waves and are relatively expensive to construct. Both the panel and the network within are unique in that their geometry is designed to dissipate sound waves at a broad range of frequencies. The present invention is absorptive, as opposed to reflective and its homogenous materials make it more durable and less susceptible to problems such as changes in thermal conditions.

In these respects, the sound barrier wall system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of reducing the transmission of noise into residential and commercially sensitive areas.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of sound barrier walls now present in the prior art, the present invention provides a new sound barrier wall system construction wherein the same can be utilized for reducing the transmission of noise into residential and commercially sensitive areas.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new sound barrier wall system that has many of the advantages of the sound barrier walls mentioned heretofore and many novel features that result in a new sound barrier wall system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art sound barrier walls, either alone or in any combination thereof.

To attain this, the present invention generally comprises a partition member having a plurality of rib members and a rear wall, and a plurality of support members positioned about the distal ends of the partition member. The partition member includes an upper slot and a lower tongue for allowing interlocking with adjacent partition members. The plurality of rib members extending from the rear wall form a sound dampening surface that breaks up the sound waves and deflects, and or dissipates the sound waves away from a residential area. A plurality of cavities preferably extend into the inner surface of the rear wall of the partition member for further increasing the sound dampening capabilities.

The partition member 20 includes an upper slot 30 and a lower tongue 40 for allowing interlocking with adjacent partition members 20. The plurality of rib members 22 extending from the rear wall 24 form a sound dampening surface that breaks up the sound waves and deflects or dissipates the sound waves away from a residential area. A plurality of cavities 26 preferably extend into the inner surface of the rear wall 24 of the partition member 20 for further increasing the sound dampening capabilities.
As shown in FIGS. 1, 2 and [0044] 8 of the drawings, the partition member 20 is preferably constructed of an elongate structure. The partition member 20 preferably has a length greater than the height and the width as best illustrated in FIG. 1 of the drawings. Even though the partition member 20 preferably have a generally elongate rectangular shape, various other shapes may be utilized to construct the overall structure of the partition member 20. In addition, the partition member 20 may be produced from various types of sound deflecting and sound absorbing materials including but not limited to concrete, plastic, fiberglass, composite materials, high density polyethylene, metal, wood and various other types of materials.
As shown in FIGS. 1 through 3 of the drawings, the [0045] partition member 20 is generally comprised of a rear wall 24, an outer perimeter extending forwardly from the rear wall 24, and a plurality of rib members 22 extending forwardly from the rear wall 24. The plurality of rib members 22 create a plurality of openings within the partition member 20 that receive and absorb sound waves (low to high frequencies). Though not illustrated in the drawings, a sound absorbing material, such as fiber or the like, may be added between the rear wall 24 and the rib members 22 for increasing the sound absorption capabilities of the partition member 20.
The plurality of [0046] rib members 22 may form various shapes, designs and patterns as illustrated in FIGS. 1, 2, 8, 11, 13, and 16 a-e. The rib member preferably create a concave shape within the inner portion of the partition member 20 as best illustrated in FIGS. 1, 3, 4 a, 7 and 9 of the drawings. The concave shape of the rib members 22 allows for increase sound absorption. In an alternative embodiment, the rib members 22 may create a convex shape within the inner portion of the partition member 20 as illustrated in FIG. 4b of the drawings.
As best illustrated in FIGS. 4[0047] a-b, 7 and 9 of the drawings, a plurality of cavities 26 extend into the inner surface of the rear wall 24 of the partition member 20 for increasing the sound absorbing capabilities of the partition member 20. The plurality of cavities 26 may have varying depths, widths, shapes and designs as can be appreciated to further increase the sound absorption capabilities of the partition member 20.
Each [0048] partition member 20 is formed for allowing interlocking to adjacent partition members 20. In a first embodiment, an upper slot 30 and a lower tongue 40 is utilized within the partition member 20 for allowing for the interlocking of the partition members 20 with one another as illustrated in FIGS. 1 and 6 of the drawings. The lower tongue 40 is inserted and retained within an upper slot 30 of a lower partition member 20.
