AGENT Patented Oct. 26, 1954 UNITED STATES PATENT OFFICE 2,692,396 PILLOWSHEET Helen B. Cheesman, Peoria, Ill. Application March 20, 1950, Serial No. 150,781

3 Claims. 1

This invention relates to a combined pillow case and sheet and more particularly to a pillowsheet characterized by novel features of construction whereby are gained improved strength and durability and increased comfort affording qualities.

The term pillowsheet as used in this specification and claims refers to a combined pillow case and sheet of the general type disclosed in my copending application Serial No. 13,710, filed March 8, 1948, now Patent No. 2,662,233, comprising a sheet to which is attached a pocket of the general shape and contour of a conventional pillow or like pad. This pocket is attached to the sheet, in a suitable manner such as by sewing, so as to leave the edges and corners free. The area upon the surface of the sheet bounded by the lines of juncture of the pocket is substantial and of suflicient and proper shape to permit formation of an opening in the area for inserting the pillow or pad into the pocket from the underside. The disclosure in my copending application is not limited thereto, but this construction is preferred especially for pillowsheets designed to be used by infants, young children or, in general, persons more or less irresponsible. Its effect is to render the pillow or pad itself extremely difficult to remove from the pocket by the sleeper.

The pocket of the pillowsheet described in my said copending application is attached to the sheet by lines of juncture which bound a rectangular area on the sheet that may be less than the area of the projection of the pillow itself upon the sheet. This provides for an overhang of the pillow upon the sheet with consonant neatness of appearance.

I have now found that this construction, as broadly described herein and in my said copending application, although having the desirable effects ascribed thereto in my said copending application, nevertheless requires substantial strength at the corners of said rectangular juncture. Manipulation of the pillowsheet in handling and of the pillow itself tends to subject these corners to a concentrated stress, and unless reinforced with care, the pillowsheet will tear or the fastening will fail at these corners. I have moreover discovered that the need for special reinforcement can be eliminated and the strength of the pillowsheet materially increased when attaching the pillow pocket to the sheet, by constructing the lines of juncture in such a manner that they form only obtuse angles with one another. The structure may be effected by constructing the juncture line in the general form of a rectangle, but with a substantial portion of each 2 right-angled corner truncated or rounded. Broadly, however, it may likewise be effected by constructing the juncture lines of any other suitable geometrical shape which possesses only obtuse angles at these points of concentrated stress. Examples are a hexagon, octagon, or the like. Moreover, the juncture line may be generally rectangular or square with rounded corners, or it may be generally elliptical or circular in shape. For the purposes of this specification and claims, and by reason of the close practical relationship between the aforesaid variations and species of construction of these juncture lines of my pillowsheet, the term obtuse angle, when used with reference to said lines, refers to both rectilinear angles greater than and to curvilinear arcs of substantial radius, the tangents of which arcs will intersect at angles greater than 90.

I have also found that the improved construction described herein not only adds considerably to the strength and durability of the pillowsheet but also adds considerably to the comfort of the sleeper in manipulating the pillow. For example, the recess between the sheet and pillowcase is free of the minor cloth obstruction that characterizes the prior right-angled corners.

Referring to the accompanying drawings, Figure 1 is a plan View of the underside of a pillowsheet showing the improved construction of the juncture line, and Figures 2 and 3 show variations thereof. Figure 4 is a cross sectional view of Figure 2, taken at line AA. In the figures, the truncated or rounded corners are shown at I, of the lines of juncture. Opening 2 secured by ties 3 is for inserting the pillow into the pillow pocket, outlined by dotted lines 4, 4. This opening may be secured by any suitable type of closure, such as for example by snaps, hook-andeyes or a Zipper.

It is to be understood that opening 2 may also be situated at any suitable place on the surface surrounding the pillow, as for example in the pillow pocket itself. It is further to be understood that the pillow pocket itself may be of any suitable shape and configuration. In the drawings it is shown as rectangular to correspond to the shape of a conventional pillow, but it may also be of the same general shape as the juncture lines, as for example, in plan, it may have obtund or rounded corners or be generally oval or circular. When containing the pillow, it may have a conventional lenticular cross section, or

it may have perpendicular or boxed sides as.

3 in each of the cases. This is illustrated by 6 in Figure 4.

I wish to point out that the boxed pillow pocket illustrated in section in Figure 4 is especially adaptable to a pad-type of pillow, although it may also be used with filled pillows of a rounded top and/or bottom contour. My present invention is particularly advantageous when employed on pillowsheets possessing a boxed pillow pocket, since there appears to be a greater tendency to grasp and manipulate this type of pillow.

Although the present invention is described with relation to the preferred embodiment in Which the juncture line between the sheet and pillow pocket encloses an area substantially less than the pocket itself, it also has within its purview pillowsheets in which the said area is substantially equal to that of thepocket itself, with the limitation, of course, that the juncture line form an area having only obtuse angles.

I claim:

1. A combined pillow case and sheet comprising a sheet section and a pillow case section, said pillow, case section comprising a pillow pocket having an opening for receiving a pillow, and said two sections joined, the lines of juncture constructed so that they form only obtuse angles 4 with one another, and the juncture lines being so situated as to leave free all edges and corners of the pillow pocket, said pillow pocket adapted to enclose a substantial portion of the under side of a pillow.

2. A combined pillow case and sheet as claimed in claim 1 in which the pillow pocket possesses perpendicular or boxed sides.

3. A combined sheet and pillow case comprising a sheet section and a pillow casesection, said pillow case section comprising a pillow pocket adapted to house a pillow, all under sides of said pocket being folded under and joined to said sheet and adapted to encase a substantial portion of the underside of a pillow, said combination having an opening into the pocket for receiving a pillow, said pocket joined to said sheet at lines of juncture constructed so that they form only obtuse angles with one another.
