' 3 claims. (ol. 20-79) Y This invention relates to an improvement in stair cushions or coverings, and the object of the invention is to provide a simple and inexpensive device of this character which may be 5 easily fitted Without cutting or other alteration to stairs of various dimensions; which will present a good appearance when in use and which may be easily cleaned and will resultantly be of great durability.

One of the objections predominant in the stair cushions and stair coverings in use at the present time is that they are required in numerous sizes to enable a proper installation to be had due to the fact that stairs vary as to width of tread and sometimes as to height of the risers. The result of this is that the stair cushions either have to be made to order to properly t the stairs for which they are intended or else a proper sizeV must be selected from stock, which requires a stock of diierent sizes to be maintained by the dealer. In some types of cushions employed, that portion of the cushion intended for fitment to the risers is separate from that portion intended for the stair tread. In such cases, 25 a space or crack is located between the riser and tread cushions, in which dust, dirt and germs can lodge and can not be readily removed.

My invention contemplates a structure in which the objections above pointed out, and others 30 found-in present day structures, are remedied and a sturdy, sanitary and long-Wearing cushion results.

In the accompanying drawing, wherein the preferred embodiment of the invention is disclosed, Fig. 1 is a plan view of a stair cushion made in accordance with this invention; Fig. 2 is a sectional view on the line 2-2 of Fig. 1, lookingin the direction of the arrows; Fig. 3 is a sec- "tional view on the line 3-3 of Fig. 1, looking in 40 the direction of the arrows; Fig. 4 is a sectional.

View of a portion of a substantially wide step showing how the cushion is fitted thereto; and Fig. 5 is a similar view showing the application of Y the cushion to a narrower step.

The improved cushion is provided with an outer cover or facing 6 composed of a suitable fabric, such as carpeting or the like. For a certain portion of its area, the cover 6 is backed by a suitable stiffener 7 which may be of cardboard, fibre, wood or thin metal or of any suitable material of sufiicient stiffness to reinforce and lend shape to that portion of the cover '7 with which it is contiguous. The edges of the stiffener 7 are secured to the cover 6 by any suitable means such as by a line of stitching indicated at 8, a suitable padding indicated at 9 filling the space between the covering and the stiffener and forming a padded cushion soft to the tread. Over three of the united edges of the covering and stiifener is placed a three-sided rigid'reinforcing strip `10 of metal which is channel-shaped in cross section and enclosesthe front and two side edges of the cushion. Y

The covering A6 is of greater size than the stiffener 7 and is thus provided with a iiexible flaplike portion 12 which projectsbeyondthe reinforcing edge piece or frame 10 so that whenvthe cushion is placed upon the tread 11 of a step,

the flap-like fiexible portion 12 extends up serving to maintain the portion 12 in flat condition. The ends 15 of the Wire frame are spaced from the ends 17 of the metal reinforcing strip 10 so that the part 12 isprovided with an inter-Y ymediate flexible area 18 between the two

frames

16 and 10 within which it may be folded to position it at substantially right angles to the padded part resting upon thev tread 11 of the step.

, From vthe foregoing, the manner in which the device is attached to a step will be clearly understood. The padded part ofthe device, enclosed and defined by the frame 10 is placed flat upon the tread l1 of the stair and is attached thereto by nails 19, screws or other fastening elements extending through the perforations 20 provided at spaced distances in the frame. In case of a relatively Wide stair tread, a part of which is shown in Fig. 4, a portion of the ap portion 12 may be used to co-operate with the padded part to cover the tread, the fold line 21 in the device by staples 23 driven into the riser and embracing the wire frame 16 as indicated in Figs. 4 and 5.

Through the use of a stair cushion as herein described, great freedom of installation without cutting and alteration and without the formation of joints or spaces in which `dust and dirt may lodge,v is provided. By shiftingthe position of the padded tread portion of the device relative to the riser portion 12, an vaccommodation of the Cil article to different stairways is attained without cutting and fitting. The flexible fold-area 18 enables any required portion of the part 12 to be utilized as tread covering, and in other cases to be used as riser covering.

Various changes and modifications may be made in the structure without departing from the spirit of the invention. For example, Where a fully flexible flap portion 12 is desired, the stiifening wire 16 may be omitted. The covering or carpeting 6 may also be composed of several joined Vsections if required. These and other changes tion so that the fabric is provided with a flexible area of substantial width located between the stiiening means and theV padded portion, within which the fabric covering may be folded at any desired point to increase or decrease the size of the riser portion of the cushion relative to the tread portion thereof 2. A stair covering provided with a padded portion adapted to overlie the tread of a step, said portion having a stili reinforcing frame extending about three of its edges and provided with a fabric covering extending over the padded portion and projecting out of the frame and adapted to project up on the riser of the step, the portion of the covering projecting up on the riser having its edges reinforced with a flexible binding, a stiffening wire located in said binding, the ends of said wire being spaced at a distance from the ends of the reinforcing frame, whereby a flexible area is located in the fabric covering between the frame and Wire within which the covering may be foldedv at any selected point to regulate the relative sizes of the tread portion and riser portion of the covering. s

3. A stair covering for attachment to the tread and riser of a step, said covering having a stiffened, padded portion adapted to overlie the tread ofa step, said portion having a fabric covering, one edge of said covering extending out beyond one edge of the stiifened, padded portion and adapted to project up against the riser of a step,

a reinforcement for the projecting part of said covering, said reinforcement having its inner end terminating at a distance from the edge of the stiffened portion so that a freely flexible area is provided in the fabric covering between the stiff-r ened portion and the reinforced portion and the sizes of these two portions relative to one another can be altered by folding the covering at a selected point within its exible area.
