' 2 Claims.'` (CL 2li-) This invention relates to certain new and use-1V ful improvements'in floor expansion joints;

The primary object of the invention is to provide a floor construction embodying expansion joint to compensate for expansion and contrac-y tion of the ooring material so t'nat the boards, strips, blocks or the like forming the component parts of the floor are maintained in properV edgei Contact. i l0 vide a floor construction of the foregoing character, wherein the expansion joint rnay be either` located adjacent the side walls or at the outer edging of the `flooring, or at points` intermediate the outer edges of the flooring,`tlie joint comprising spring elements of any appropriate character for maintaining lthe component parts of the flooring in intimate edge contact. Y

Itis a further object of the invention to provide an expansion joint rfor flooring wherein `a Cover plate is secured along one edgel to a flooring element with its opposite side edge 'freely supported upon the edge of an adjacent'iiooring elementy to ride thereon during expansion andcontraction of the iiooringelements with spring devices disposed beneatli the cover plate and be" tween adjacent iiooring elements for maintaining proper edge contact of the flooring elements.

With the above and other objects in view that will become'apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings:- y y Figure 1 is an edge elevational view of a licoring construction with an adjacent wall shown in section, a relatively wide moulding strip overlying the adjacent edge of a ooring element with the latter spaced from the base board of the wall and with expansion springs between the base board and flooring element;

Figure 2 is a horizontal sectional view taken on line 2-2 of Figure 1 snowing the coil springs embodied in the expansion joints;

Figure 3 is a detail sectional view showing a continuous wavy or corrugated spring of the ,go-expansion joint;

Figure i is a detail sectional View with flat curved spring elements;

Figure 5 is a fragmentary side elevational View of a spring unit comprised of side bars of angle `formation connected by coil springs;

A further object of this invention is rto pro Figure 6 is atopplan view of unit shown in Figure 5; l

Figure '7 is a cross-sectional view taken on line 7-7 of Figure 6, snowing the channel bar for# mation of the side strips of the spring unit;

Figure 8 is a fragmentary perspective View' showing an expansion joint arranged interme-` diate the opposite edges of a flooring and ern-l bodying a cover plate secured along one edge to a iiooring elementand freely engaged with an adjacent flooring element; y

Figure 9' is a detail cross-sectional view of the flooring construction and expansion joint illustrated in Figure 8, showing the normal position of the flooring elements and cover plate; i0

' Figureli is a detail sectional view, similar to Figure 9, showing' the iiooring elements expanded with the springs of the expansion joint under compression;

Figure l1 is a detail sectional view, similar to Figure 9,"sl1owing the iiooring elements retracted with the springs of the joints under expansion;

Figure 12 is a detail sectional view showing a relatively Wide base moulding strip with depression springs disposed `therebeneatlo. and en- Go gagedwith the edge element of a flooring construction; and A.

Figure 13 is a detail sectional view showing a metallic moulding strip `of angle formation.

Referring more in detail to the accompanying drawings and particularly to Figuresi and 2, the reference numeral 15 designates the sub-structure of a floor that has side wall beams 16 rising therefrom that are faced by base boards 17. The flooring is illustrated as of the parquet type comprising flooring elements 13 supported on the sub-structure 15 through the medium of a masticy 19 or other suitable material, the licoring elements 18 at the outer edges of the flooringv being spaced from the base board 17 and extend-Y C3 ing under the usual moulding strip 20.

To maintain the flooring elements 18 in intimate edge contact, a plurality of coil springs 21 are interposed between the lower end of the base board 1'7 andV adjacent edge flooring elements, thel coil springs 21 being engaged with and suitably secured to abutment strips 22 shown in Figure 2. The nooring elements 18 are freely eXpansible and contractible, movement thereof being perinitted by the expansion joint comprising the springs 21 so that warping of the ooring element is eliminated.

Another forni of spring element for the expansion joint is illustratedin Figure 3, the spring 23 A being of the wavy or corrugated type and continthe spring uous for the length and breadth of the flooring.

The form of spring element 24 illustrated in Figure 4 is comprised of sections bent to have the intermediate part 25 thereof engaged with a facing strip 22 and the opposite ends 26 engage with the opposing facing strip 22.

Another form of spring unit is illustrated in Figures 5 to 7 and is comprised of a pair of channel irons 27 having their hanged edges directed toward each other with a series of coil springs 28 interposed therebetween and attached at their opposite ends as at 29 to the channel irons.

In the form of expansion joint illustrated in Figures 8 to 11, the same is located intermediate opposite edges of a flooring construction and ern-` bodies a cover plate that may be representative and function as a flooring element. The flooring elements 30 and 31 are spaced from each other to provide an expansion joint that includes a cover plate 32 that is secured along one edge as at 83 in a mitered corner 34 of the flooring element 30 to lie flush with the upper surface of the flooring elements 30 and 31, the adjacent upper corner edge of the flooring element 31 being longitudinally grooved as at 35 for the reception of the free edge of the cover plate 32 that is undercut or beveled as at 32dr to provide an easy riding contact between the cover plates and flooring element 31. A plurality` of coil springs 36, each have a block mounting 37 at opposite ends that are suitably secured to adjacent edges Yof the ooringelements 30 and 31 as illustrated. The normal position of the ilooring elements 30 and 3l and the cover plates 32 are illustrated in Figure 9, the cover plates spanning the expansion joint space between the flooring elements to provide an uninterrupted floor surface. Upon eX- pansion of the flooring elements, the same move toward each other, resulting in compression of vthe springs 36 while theiree edge of the cover plate 32 moves into the recess Vedge 35 vof the ooring element 31 to assume the position shown in Figure 10, while upon contraction of the flooring elements, the latter are separated as illustrated in Figure l1 while the cover plate 32 remains in spanning relation to the expansion joint.

In the form of expansion joint illustrated in Figure 12, the moulding strip 20a is comparatively Wide with an edge of the ooring element 38 extending thereunder. The lower end of the Wall 17d is pocketed as at 39 and coil springs 40 are disposed in said pocket for engagement with the flooring element 38.

In lieu of the moulding strip, an angle iron strip as illustrated in Figure 13 may be employed, the horizontal portion 40 of the angle stripoverlying the adjacent Yedge of the flooring element 41 while the vertical angle end 42 of the angle strip is secured as at 43 to the Wall 44. The expansion joint spring 45 is interposed between the wall 44 and adjacent edge of the flooring element 41.

In each form of the invention, the flooring elements are laid in a manner to permit expansion and contraction movements thereof and edge contacts of the flooring elements are maintained by expansion joints associated with the ooring construction. In the forms of the invention illustrated in Figures l to 4, l2 and 13, the expansion joints to compensate for expansion and contraction of the flooring elements are located at the outer edge of the ooring construction, While in Figures 8 to ll, the expansion joint may be disposed at any point intermediate the edges of the iooring structure with the cover plate 32 overlying the open space aiording the expansion joint.

While there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

1. In a floor construction, ooring elements laid with a space between chosen adjacent elements,

the `upper sides of the adjacent elements being rabbeted at the spaced edges thereof,r a coverr plate for the space between the flooring elements secured in one of the rabbeted edges with its opposite side overlapping the other adjacent flooring element and slidable in the rabbeted portion thereof and spring elements in the space between adjacent spaced flooring elements including a spring assembly having strip plates an-l chored to the opposed side edges of the flooring elements and expansion springs interposed between and secured to the strip plates.

2. In a floor construction, flooring elements laid with a space between chosen adjacent elements, the upper sides of the adjacent elements being rabbeted at the spaced edges thereof, a cover plate for .the space between the flooring elements secured in one of the rabbeted edges with its opposite side overlapping the other adjacent floor-l ing element and slidable in the rabbeted portion thereof and spring elements in the space between adjacent spaced flooring ,eiements including a spring assembly having strip plates anchored to the opposed side edges of the ooring elements and expansion springs interposed between and.
