In the pre~erred embodiment, the underlayment 30 i5 at least ons-half inch thick and the grooves extend approxima~ely 3~4ths of the way ~h~ough ths resilien~ underlayment 30.
Although various typas of support members 38 made of differen~ materials can be used, in the embodiment illustrated in Figs. l through 4.
each of the support members 3~ comprise~ a channel 46 made of sixteen gauge zinc plated steel. As illustrated in Fig. 4, the steel channel q6 ha~ a flattened C-type configuratio~ comprising a horizon~al base portion 50, two spaced apart vertical side portions 54 e~tending from th~ base portion 500 and two upper horizontal flangR portions 58 ~hich extend from the vertical side portions 54 towald each other. The horizontal flanges 5& do not reach each other and thers~or~ leave an opening into ~ho interior of the channel 46. The dimen~ion between the uppsr outer surface and the lower outer urface of each channel 46 is approximately the same as each groo~e 34. As a result. the upper surfaca of each channel 46 i8 flush with the upper surface of the underlayment 30 between the groove~ 34.
As illustra~ed in Figs. 2 and 4, the underlay~en~ 30 and seeel channel~ 46 are serured to the ~oundaeion lg by means of anchor~ S2 driven through the cha~nels 46 a~ approxima~ely four~een inch intervals.
The strips 42 of resilient material are preferably made of rubber and are placed on the underlayment 30 between the parallel grooves 34 which receive the support members 38. In the preferred embodiment, each of the rubber strips 42 extends nearly the full width of the fLooring system 10.
Other types of resilient materials such as polyurethane and PVC may be used.
In other embodiments, the strips 42 can be spaced at intervals across the flooring system 10.
~ s illustrated in Figure 4~ in the preferred embodiment, the rubber strips 42 are held in grooves 66 in the underlayment 30, and the depth of each rubber strip groove 66 is less than the uncompressed thickness of each rubber strip 42. In other embodiments (not shown), the rubber strips 42 can lay on and de:Elect the upper surface of resilient underlayment 30 or can be held i.n grooves in the :E:Loorboards 22 superposed on the support members 38 and the rubber strips 42. The depth of each such rubber strip groove in the floorboards 22 would be less than the uncompressed thickness of each rubber strip 42.
As illustrated in Figure 1, superposed at right angles on the support members 38 and the rubber strips 42 are adjacent rows of the floorboards 22 with tongues 70 and grooves 74. the floorboards 22 cover the subfloor assembly 18 and the ends of the floorboards 22 are staggered from row to row.
As illustrated in Figure 1, the floorboards 22 are secured in place by means 78 for fastening the floorboards 22 to the support members 38 so that the rubber strips 42 are in compression between the floorboards 22 and the underlayment 30. In the embodiment illustrated in Figures 2, 3 and 4, the means 78 for fastening the floorboards to the steel channels comprises a plurality of clips 82.
~L~59~

The edges 102 o~ the central vertical poction 86 are rec~s~d to ceceive the horizontal ~langes 58 o~ the flattened C-shaped channel 46. As a result. portions 106 of the ver~ical portion 86 are held below the horizontal flanges 58, thus securing the clip 82 in the steel channel 46. To pos;tion the clip a~ i~ the chan~el 46, the clip 82 is inser~ed into the channel 46 and then rotated so the lower portions lOOE o~ the vertical portion 86 are below the channel flanges 58.
As illustrated in Fig. 2, the upper horizontal portion 90 of each cli~ ~2 is received in a groove 110 which is in the side of each ~loorboard 22 and which extends into the floorboard 22 beneath the tongue 70. In other embodiment~, (not shown) the horizontal portion 90 can ba receiYed below ~he tongue 70 in an enlarged version of the groove 74 provided for the tongue 70.
The clip ~2 fur~her includes a triangular shap~d pro~g 11~ which extend~ from the ~op of the v~rtical ce~tral portion ~6 in a direct~on ~s~
opposite the hori~ontal portion 90. The triangular prong 114 helps hold the floorboards 22 and assists in the assembly of the flooring system 10 in the following manner. After a floorboard 22 is superposed at a right angle over the steel channel 46, the clip 82 is secured to the floorboard 22 by inserting the hori~ontal portion 86 of the clip 82 into the groove 110 of the floor-board 22. Another floorboard 22 is laid adjacent the prior floorboard and the prong 114 is forced into the floorboard to hold it in place. As illustrated in Figure 1, the clips 82 are used to secure the floorboards 22 in each area of a side of a floorboard 22 above a steel channel 46.
As illu8 trated in Figure 4, to finish the flooring system, molding 118 is nailed to the floorboards 22 around the perimeter of the E:Loorboarcls 22 to cover any per:Lmeter voLds.
An alternate embodiment 122 of the flooring system 10 is shown in Figures 5 through 7. Various components of the flooring system 122 are the same as the flooring system 10 shown in Figures 1, 2 and 4, and like numerals are used to designate similar elements.
In embodiment 122, the support members 38 comprise laminated strips 126. The depth of each laminated strip 126 is approximately the same as each groove 34. Each laminated strip 126 comprises a first lower metal strip 130, a second upper metal strip 134, and a wood strip 138 connected between the first metal strip 130 and the second metal strip 134.
In the preferred embodiment, the lower metal strip 130 is made of sixteen gauge steel, the upper metal strip 134 is made of thirty gauge steel, and the wood strip 138 is made of hard maple. The laminated strips 126 are laid end to end in the parallel grooves 34 in the underlayment 30 and secured to ~he foundation 14 by anchors 62 spaced at ~ourteen inch in~ervals, and the ends of the laminated ætrips 126 are staggered from row to row.
In the embodiment 122, the means 78 for fastenin~ the floorboards 22 to ehe laminated strips 126 comprises anchors 142 which are driYen at an angle into the floorboards 22 above the tongue 70 in 10 the area of the floorboards 22 above the laminated strips 12~. -Th~ anchors 142 are driven through the floorboard Z2 and through the upe~r strip 134. and then through the wood strip 13~, where ths anchors 142 are then deflected off the lower strip 130 back 15 into the wood strip 138.
In the embodiment 122, the peeimeter of Che 100ring sy~tem is finished with a ventilating eubber base 146 which is secured to the floorboards 2Z by an appropriate adhesive.
Various of the featu~es~ of the invention are set forth in the following cldims.
