l. MARINSKY April 2, 1963 BED SHEET Filed March 20, 1961 INVENTOR. ISAAC MARINSKY ATTOR Y United States nice 3,083,379 BED SHEET Isaac Marinsky, 172 /2 Somerset St, Providence, RI. Filed Mar. 20, 1961, Ser. No. 96,767 1 Claim. (Cl. -334) My present invention relates to removable covers for mattresses, and more particularly to a novel construction of a bed sheet.

The principal object of the present invention is to provide a bed sheet which can be locked to the mattress to provide a smooth overlying top portion which will not pull or wrinkle.

Another object of the present invention is to provide a bed sheet which can be locked at the corners of the mattress but which when removed will iron fiat without wrinkling.

A further object of the present invention is to provide a bed sheet which can be simply and quickly locked to or removed from a mattress.

Another object of the present invention is to provide a bed sheet which is simple in construction and easy and economical to manufacture and assemble.

-With the above and other objects and advantageous features in view my invention consists of a novel arrangement of parts more fully disclosed in the detailed description following in conjunction with the accompanying drawings and more particularly defined in the appended claim.

In the drawings,

FIG. 1 is a plan view of a bed sheet embodying my invention.

FIG. 2 is an enlarged perspective view of one corner of the sheet locked to a mattress.

FFiG. 3 is a plan view of an alternative corner construction.

FIG. 4 is a perspective view showing the construction of FIG. 3 locked to a mattress.

FIG. 5 is a plan view of another form of corner construction.

FIG. 6 is a perspective view of the form shown in FIG. 5 locked to a mattress.

So called under sheets, used to cover the mattress have always presented a problem in holding them smoothly in position. The standard practice is to tuck the trailing edges of the sheet under the mattress. {This has been found unsatisfactory because the sheet pulls and will not lie smooth. Attempts have been made to provide fastening devices for fastening the corners of the sheet to the mattress. However, the corners of the mattress are rounded and there is therefore much wrinkling at all four corners. Contour sheets have been provided with pockets at the corners to receive the mattress. Most of these present laundering problems since they will not lie flat when being ironed. Slide fasteners have also been provided. Such fasteners cannot stand repeated washing and ironing and quickly lose their elfectiveness. The present invention is designed to overcome these diiiiculties by providing a sheet construction which will lie flat when being laundered and will conform to the rounded corners on the mattress when being locked thereto without wrinkling. The present invention provides a certain basic type of construction with several alternative fastening methods.

FIG. 1 illustrates the sheet 10 having a central rectangular area 11 of a size to cover the top of the mattress indicated in the broken lines 12. The portion 11 is provided at each end with extended integral portions 13 and at each side edge with extended integral portions 14. The portions 13 and 14 are of sufficient width to cover the sides of the mattress and preferably slightly below it.

The sheet 10 is locked to the mattress at each corner by the several methods illustrated in the drawings. To fit the rounded corners of the mattress, the top portion 11 is rounded off at each corner at 15 to provide a cut out area 16 so that the ends of the portions 13 and 14 form flaps which are separated from the arcuate portion 15 at each corner. The ends of the portions 13 and 14 are also cut out to form a cut out portion 17 at each corner. The entire corner area may be reinforced by a double fold of material attached to the sheet 11 along the dotted lines 18. Now viewing FIG; 2, when the sheet is placed on a mattress the top portion 11 will lie smoothly without wrinkling, the arcuate portion 15 covering the rounded upper part of the mattress. The ends of the portions 13 and 14- will fit smoothly around the corner of the mattress and can be locked to each other by snap fasteners 19. Since the mattress is soft and yielding, the sheet may be made one half to one inch shorter and narrower than the mattress. This will draw the sheet tightly into position and the top part 11 will always lie smoothly.

With the above construction there can be no wrinkling of the sheet while in position, the cut out portion 16 at the corners 15 permitting the sheet to lie smoothly over the rounded corners of the mattress. When the sheet is removed by opening the fasteners 19, it will lie flat as shown in FIG. 1 and can be readily laundered and ironed. The entire sheet is simple in construction and is easy to lock in position and to remove.

In the form shown in FIGS. 3 and 4, a different type of locking member is provided which eliminates the use of any metal. Furthermore, while the form shown in FIGS. 1 and 2 shows the portions 13 and 14 locked to each other at the corner, the form shown in FIGS. 3 and 4 shows this locking action at one side. Actually, any of the locking means can be used either at the corner or at one side. In this form the sheet 20 is provided at the corner with the arcuate portion 21 for fitting the rounded corner of the mattress. However, the longitudinal portion 22 is extended beyond the corner while the lateral portion 23 is cut short of the corner. The portion 23 is provided with a transverse slot 24 in the form of an enlarged buttonhole. The end of the longitudinal portion 22 is provided with a T-shaped member 25 which may be integral with it or sewed separately to it. The portion 25 is impregnated with a starchy chemical for stiffening purposes. Viewing FIG. 4, when the sheet is being locked to the mattress, the enlarged head of the portion 25 is folded so as to pass into the buttonhole opening 24 to hold the parts together.

In the form shown in FIGS. 5 and 6, the sheet 26 is again provided with the arcuate corner 27 and cut out portion 28 to separate the ends of the side member 29 and longitudinal member 39. In this case the locking member comprises a pair of spaced buttonholes 31 positioned at the end of the member 29 and a flexible plastic member 32 having an intermediate body portion 33 sewn into the end of the member 30. The free ends 34 of the member 32 are pushed into the buttonholes 31 by bending the members 32 to shorten the distance between the ends. The intermediate portion 33 may be wider than the ends so that the member 30 will not slide longitudinally after it is sewn in position. This form of look ing member can also be used to hold the next sheet in position at the corner. As shown in FIG. 2 a member 35 similar to the member 32 can be sewn at an angle adjacent each corner on the top of the sheet. It will therefore be merely necessary to provide the covering sheet or the next sheet with spaced buttonholes to lock it in place. Since this sheet is usually used beneath a blanket and folded back at the head end of the bed the mattress so that it can be locked in position Without wrinkling. The slotted rounded corners free the locking portions so that they can be handled without wrinkling the top portion of the sheet. Furthermore, any of the forms will open fiat to permit laundering and ironing. Other advantages of the present invention will be readily apparent to a person skilled in the art.

I claim:

A bed sheet construction comprising a central rectangular portion for covering the top of a mattress, end and side portions extending integrally from said central "portion and adapted to extend vertically to cover the ends and sides of the mattress, each corner of said rectangular portion having an arcuate slot forming a rounded corner on said rectangular portion adapted to overlie the rounded corners of the mattress, said slot separating the adjacent ends of said end and side portions from said central portion to'form end flaps, and fastening means for releasably joining said flaps, said fastening means including a plurality of snap fasteners along the adjacent ends of said flaps, the corners of said sheet including the slots and flaps being reinforced With a double thickness of material.
