1. Field of the Invention
The present invention relates generally to floor systems. More particularly, the present invention concerns an athletic floor system and a method of assembly. The product and method for constructing an athletic floor allow for flooring to be more cost-effective while retaining the same amount of springiness afforded by more expensive flooring systems.
2. Discussion of the Prior Art
A shock-absorbent athletic floor system without vibrations has been the goal of many previous efforts by others. Many athletic floors are either too loose and have floating members and dead spots, or are fastened so tight that there is little or no shock-absorbing capacity. Moreover, many prior art floors are difficult to install and suffer from having guide channels that are rendered immobile because they are fastened directly to a concrete foundation. In such systems, the insertion of springs, foam pads, and/or the like into the subfloor does not overcome the fact that the guide channels are pinned down directly to the foundation, eliminating the possibility for the system to breath and rise above the foundation beneath it. This is but one example of non-optimal design in flooring systems of the prior art and is not necessarily present in all previous flooring systems. Nevertheless, through the summary of the invention and the detailed description of the drawings in the ensuing disclosure, benefits of the presently disclosed flooring system over prior art systems become apparent.

This presently disclosed subject matter concerns floor systems that are adapted to allow floor slats (alternatively referred to as “boards”) to translate up and down within defined limits, and methods of assembling the floor systems. The floor systems disclosed herein operate in conjunction with sections of floor material that are elevated above a solid foundation with foam, one or more rubber pads, and/or the like. As disclosed herein, due to the arrangement and shapes of the components of floor systems in accordance with the present invention, once assembled, one or more tunnels exist below the top surface of the floor, allowing air to flow therethrough. Due to the indirect anchoring of the sections of floor material to a solid foundation, such as a concrete floor, as described herein, each section of floor is allowed to independently translate upward and downward in a shock-absorbing manner.
In one embodiment of a floor system according to the presently disclosed subject matter, elongated channels having a vertical planar portion and a horizontal planar portion, which have an inverted L-shape, when viewed in cross-section, run lengthwise along the sides of sections of subfloor material. The horizontal and vertical planar sections of such a channel engage with at least one section of subfloor material and indirectly anchor it to the solid foundation below. The channel is movably anchored to the solid foundation with at least one bracket which is directly anchored to the foundation and which slidably engages with the channel through a slot located in the vertical plane of the channel. In such an embodiment, the one or more sections of the layer of subfloor material with which the channel interfaces are below a top layer of sections of floor material, which are affixed thereto.
In another embodiment according to the presently disclosed subject matter, one or more channels having a T-shape, when viewed in cross-section, interfaces with the ends of sections of floor material. Unlike the embodiment with the inverted L-shaped channel discussed above, the T-shaped channels of this embodiment interface with sections of floor material that are not below another layer of floor or subfloor material, but rather are the top and, preferably, the only layer of floor slats. This gives the floor system a low profile. Each T-shaped channel according to this embodiment also includes at least one slot in the vertical plane through which an anchored bracket slidably engages with the channel.
The sections of floor or subfloor with which the channels engage are supported underneath by a resilient, shock-absorbing material, such as rubber pads, which are preferably evenly spaced, a layer of foam, or the like. The resilient, shock-absorbing supporting material affords sections of floor supported thereon a certain measure of springiness. In one embodiment which includes the inverted L-shaped channel, a ¾-inch layer of maple slats is nailed to a ¾-inch layer of plywood. Such an embodiment is primarily adapted for gymnasiums. It provides a cost-efficient alternative to standard maple floor, which normally uses maple slats of higher thickness than the ¾-inch slats. Of course, floor sections comprising a material other than slats of maple may be employed, but maple is preferable. A second embodiment, in which the T-shaped channels interface directly with a top layer of floor slats, which are preferably maple, is a cost-efficient alternative to more expensive floors, while providing roughly the same amount of springiness.

The following is a brief description of the drawings, which correspond with exemplary embodiments of floor systems in accordance with the present invention.
The channel 110 is designed to engage with a plywood panel. See
U-shaped portion 117 engages with the channel 110. That is, the inverted U-shaped portion 117 of bracket 116 is placed into the first, taller portion 119 of the longitudinal slot 114. The second, shorter portion 121 of the longitudinal slot 114 is sized to allow the channel 110 to be moveably engaged with the bracket 116, such that the channel 110 may move up and down inside the inverted U-shaped portion 117 of the bracket 116 without becoming disengaged therefrom. The channel 110 can be indirectly nailed, screwed, or otherwise anchored to a solid foundation, for example concrete. See
The vertical planar portion 211 of the T-shaped channel 210 is then engaged by bracket 216. That is, the inverted U-shaped portion 217 is inserted into the first, taller portion 219 of the longitudinal slot 214. The shorter second portion 221 of the longitudinal slot 214 is sized to allow the channel 210 to be moveably engaged with the bracket 216. The channel 210 is then indirectly anchored to a concrete foundation by the bracket 216. The horizontal planar portion 215 of the bracket 216 is anchored to the concrete foundation 326 in
The next step is placing a section of an intermediate layer of subfloor material 418 on top of the resilient, shock-absorbing materials 412 and 422. The sections of the intermediate layer of subfloor material 418 are positioned in a side-by-side orientation, leaving gaps between them. The gaps are of the same width as the horizontal planar portion of the bracket 416. In this example, the intermediate layer of subfloor material is plywood 418. The plywood in this example is ¾″ thick. As will be understood by those skilled in the art, other subfloor materials, for example plank boards, oriented strand board (“OSB”), and/or particle board may be placed atop the resilient, shock-absorbing materials, 412 and 422, instead of or in addition to plywood. Also, as those skilled in the art will appreciate, the thickness of the intermediate layer of subfloor material 418 may be more or less than ¾″, provided that the cooperating components in the floor system, for example the bracket 416 and/or inverted L-shaped channel 410, are adjusted accordingly.
The next step is positioning the horizontal planar portion of each channel 410 upon each section of the intermediate layer of subfloor material 418, such that the vertical portion of the channel is substantially against a corresponding side of a section of the intermediate layer of subfloor material 418. The next step is inserting the inverted U-shaped portion of bracket 416 into a longitudinal slot in the vertical planar portion of the corresponding channel 410. Preferably, the inverted U-shaped portion of the bracket 416 is inserted into the taller portion of the longitudinal slot 414 and then slid into the shorter portion of the longitudinal slot 414. The next step is anchoring bracket 416 to the solid foundation 426. In this particular embodiment, at least one anchor 424 is set into the horizontal planar portion of the L-shaped bracket 416.
The next step is to place sections of a top layer of floor material 420 across the top of the intermediate layer of subfloor material 418, such that no gaps exist between the sections of the top layer of floor material 420. In this particular embodiment, the top layer comprises ¾″ thick, tongue and grooved slats of maple 420 arranged parallel to each other.
As a person skilled in the art will appreciate, other materials and thicknesses may be used for the top layer of floor material 420. The next step is nailing the top layer of floor material 420 to the intermediate layer of subfloor material 418. In this embodiment, the top layer of floor material 420 is nailed to the intermediate layer of subfloor material 418. As shown, in assembled form, a tunnel 428 allows air to flow underneath the top layer of floor material 420 and alongside the sections of the intermediate layer of subfloor material 418 and the resilient, shock-absorbing material 412 and 422.
In other embodiments, screws, tacks, staples, glue, or other mechanisms or substances may be used to affix and/or anchor the above-discussed components. A person skilled in the art, upon reviewing the above-disclosed method and the corresponding
The next step is anchoring bracket 516 into the solid foundation 526, without any of the resilient, shock-absorbing material 512 between the bracket 516 and solid foundation 526. This may be done by removing resilient, shock-absorbing material 512 at each location where a bracket 516 is to be placed, or by arranging the resilient, shock-absorbing material such that it is otherwise not occupying the space where the bracket 516 is to be positioned. The bracket 516 is anchored to the solid foundation 526 in this embodiment with at least one nail 524.
The next step is placing sections of a top layer of floor material 518 over the resilient, shock-absorbing material. The placement of the sections of the top layer 518 is performed in an end-to-end manner, such that the horizontal planar section of the T-shaped channel engages with a groove 525 in a first end of a first section of floor material 518 and a groove 523 in a second end of a second section of floor material 518 which is disposed opposite to the first section of floor material. In this particular embodiment, the sections of the top layer of floor material 518 comprise maple which is ¾″ thick. As a person skilled in the art will appreciate, other materials and thicknesses may be used for the top layer of floor material 518. The next step is inserting the inverted U-shaped portion of bracket 516 into the longitudinal slot 514 on the vertical planar portion of the corresponding channel 510. Preferably, the inverted U-shaped portion is inserted into the taller portion of the longitudinal slot and then slid into the shorter portion of the longitudinal slot. The resulting tunnel 528 beneath the top layer of floor material, as shown in
In alternative embodiment, the method of assembly is as discussed immediately above, with the following difference. After the step of anchoring the bracket 516 to the solid foundation 526, the sections of a top layer 518 of floor material are placed over the resilient, shock-absorbing material 512 and engaged with the channel 510 as follows: A first side of the horizontal planar portion 509 of the channel 510 is engaged with a groove 525 in a first end of a first section of floor material, then the inverted U-shaped portion of the bracket is inserted into the longitudinal slot 514, in the channel 510, then the opposite side of the horizontal portion 509 of the channel 510 is engaged with a groove 523 in a second end of a second section of top floor material, which is disposed opposite to the first section of floor material.
In other embodiments, screws, tacks, staples, glue, or other mechanisms or substances may be used to affix and/or anchor the above-discussed components. A person skilled in the art, upon reviewing the above-disclosed method and the corresponding
While preferred embodiments of the disclosed subject matter have been described, so as to enable one of skill in the art to practice the present disclosed subject matter, the preceding description is intended to be exemplary only.
