Definitions
- the present invention relates to improvements in my prior flooring system which for some types of installation enhances the effect of and in other types installations eliminates the necessity for the splines or holding inserts.
- the present invention further relates to improvements in flooring systems of the character aforesaid by which the effect of shrinkage of the boards is minimized by preventing passage of air with respect thereto.
- the present invention further relates to improvements in flooring systems of the character aforesaid by which the advantage of tongued and grooved boards may be utilized with the hold down clips of my prior flooring system.
- the present invention further relates to improvement-s in flooring systems which are highly advantageous from the viewpoint of decreased cost of installation.
- the present invention further relates to flooring system of the character aforesaid but which are easier to install and do not require experienced or skilled workmen to install a floor having highly advantageous characteristics as to installation and performance.
- FIGURE 1 is a top plan view of flooring in accordance with the invention.
- FIG. 2 is a fragmentary perspective view of a portion of one of the channels and of clips employed therewith;
- FIG. 3 is a vertical sectional view, enlarged, taken approximately on the line 33 of FIG. 1;
- FIG. 4 is a fragmentary vertical sectional view, taken approximately on the line 44 of FIG. 3;
- FIG. 5 is a view similar to FIG. 4 showing a modified form of the invention.
- a supporting base 10 which may consist of wood, concrete or other subfloor, is provided upon which a plurality of channels 11 are secured in parallel relation and in level condition as in my prior patent, but preferably by the use of explosively applied fasteners (not shown).
- Each of the channels 11 has side marginal portions 16 extending upwardly from the web 13 with inwardly extending rims 17 substantially parallel to the web 13.
- the channels 11 are formed to close dimensional tolerances for enhancing their clip holding action, as hereinafter explained.
- the channels 11 can be made of any desired material of adequate strength and preferably of mild steel with a heavy galvanizing or other resistant coating to prevent rusting.
- a plurality of metallic clips 20 are provided, as in my prior patent, each having a central vertical plate portion 21, and lower oppositely extending horizontally disposed feet 22, the corners 23 of the feet 22 being rounded to aid in assembly to the channels 11.
- the central plate portions 21 are provided with notches 24 extending inwardly from each side marginal edge for the accommodation of the rims 17.
- the notches 24 have corner chamfers 25 for disposition at the intersection of the inner faces of the rims 17 and the inner faces of marginal portions 16 of the channels 11.
- fingers 26 are provided with beveled end portions 27 and tapered margins 28.
- the fingers 26 are slightly inclined upwardly and outwardly for a stronger holding action when in their final positions.
- the floor boards 30 employed with the flooring system are of wood which can be milled or shaped to close dimensional tolerances, hard maple being particularly suitable.
- Each of the floor boards 30 used in connection with the system of the present invention preferably has fi'at longitudinal top and bottom faces 31 and 32 and at a predetermined distance from the bottom face 32, has a longitudinal slot or groove 33 formed therealong on each side thereof.
- the bottom faces 32 preferably have extending therealong substantially rectangular stress relieving cut outs or grooves 29.
- the grooves 33 should be about one quarter of the distance between the top face 31 and the bottom face 32, and closer to the bottom face 32 than to the top face 31, so that an increased wearing part is provided on each board 30 while still providing adequate holding and avoiding splitting.
- Each board 30 has a lower vertical side wall face 35 extending downwardly from the groove 33 with a beveled face 36 connecting the bottom of the groove 33 and the lower side wall face 35.
- the beveled face 36 is at a location such that the clip finger 26 at its intersection with the plate portion 21 engages thereon.
- the faces 35 of contiguous boards 30 are located, and positioned by the plate portions 21 of the clips '20 between the faces 35, so that when the boards 30 are in their assembled positions the portions of the boards above the grooves 33 are in meeting and engaging relation.
- the grooves 33 may also serve for the reception of splines or holding inserts 37 which may be positioned intermediate the clips 20 and channels 11 for retaining the boards 30 against warping and also against independent deflection between the clips 20, under certain conditions.
- the holding inserts 37 will not be required, the edges of the boards 30 being held against relative vertical movement and warping by structure to be described.
- the tongues 40 in vertical cross section, can have from end to end thereof flat upper and lower faces 43 and 44 connected by an arcuate face 45.
- the tongues each engage in a complemental longitudinal groove 46 in the adjoining board 30, with upper and lower vertical longitudinal faces 47 and 48 respectively engaging the faces 43 and 44.
- the elevation of the tongues 40 and grooves 46 can be varied but are preferably not so close to the grooves 33 to weaken the board at this location nor so close to the top face 31 as to reduce its effectiveness upon the occurrence of wear.
- Each floor board 30, as shown in FIG. 5, and between the top face 3 1 and the slot or groove 33 has upper and lower outwardly disposed inclined meeting faces 49 and 50, providing longitudinal tongues 51 from end to end.
- the tongues 51 each engage in a complemental groove 52 in the adjoining board 36 formed by inclined meeting edge faces 53 and 54.
- the channels 11 are mounted in spaced, parallel relation, as heretofore pointed out, on the sub floors.
- a plurality of clips 28 are inserted in the channels 11 and turned so that the plate portions Z-Elthereof are transversely disposed with respect to the channels 11.
- the clips 20 Upon turning of the clips 20 they will be moved to a position so that the feet 22 are in firm gripping relation with the inner face of the central horizontal web 13.
- the upwardly facing portions of the notches 24 are in firm gripping engagement with the under sides of the rims 17 and to an extent to cut into and slightly deform the channel 11 for this purpose.
- the floor boards 30 are now brought successively to positions with their lower faces 32 supported by the upper faces of the rims 17 and are moved to positions to engage the holding fingers 26 in the grooves 33.
- the holding fingers 26 urge the boards 3t downwardly into gripping engagement with the upper faces of the rims 17.
- the holding insets 37 may be provided and if employed aid in preventing warpage and also independent movement or deflection of one floor board 30 with respect to the next, and permit sanding of the boards as required down to the grooves 33 and thus to greater depth than if reliance is had only on the tongues and grooves to prevent deflection which would only permit sanding down to the surface 43.
- a flooring system comprising: a plurality of spaced parallel channels each with a pair of spaced rims having upper face portions,
- draw-down clips having lower portions in gripping engagement with each of said channels and having at least one upper outwardly extending board engaging portion above said channels,
- each of said boards on one side thereof spaced intermediate the upper and lower faces of the board having a tongue with upper and lower horizontal face portions and opposite thereto a tongue receiving groove with upper and lower horizontal face portions,
- said upper and lower face portions of a tongue of one board being in substantially continuous engagement with said upper and lower face portions of a groove of the next board for restraining independent vertical movement of one of said boards with respect to the other and for preventing warpage
- said boards each having along at least one side margin thereof a longitudinally extending side marginal groove spaced below the tongues and tonguie receiving grooves with a bottom horizontal face,
- said marginal groove being in more closely spaced relation to the lower horizontal face than to said upper wear face
- said clips being disposed at the intersection of each of said boards with each of said channels and including a gripping finger extending into one of said marginal grooves and in engagement therewith and urging said boards downwardly into engagement with the rims of the channel.
- said clips have portions in engagement with said side marginal grooves in contiguous boards.
