Application May 28, 1956, Serial No. 587,575

2 Claims. (Cl. 2472.5)

The present invention relates to the class of sheets commonly known as contour sheets. Bed sheets of this type are adapted to be fitted at their corners about the corners of a mattress, so as to be held in position upon the mattress.

The present invention is an improvement on existing sheets of this type, in respect to providing an improved 7 means extending diagonally of the corners of the contour sheet, designed to effectively tension the sheet about the mattress. Said means is so designed as to be readily removable, adjustable in length, and, further, adapted for connection to conventional sheets, that is, sheets that are not provided with corner pockets, so that the conventional sheets can be swiftly adapted for use as a contour sheet similar to one having sewed in corner pockets.

Another object of importance is to provide a means connectable diagonally across the corners of a sheet, so designed as to be capable of manufacture at low cost, and to remain in a selected position of adjustment, so as to provide a continuing pull upon the'sheet, effective to maintain the proper tension upon the sheet as long as the sheet is on the bed.

Another object of importance is to provide, in a device of the type referred to, clasp means in the form of elongated, resilient, peripherally flanged buttons detachably connectable to the sides and ends of the sheet, with said buttons being adapted for engagement in loops provided upon the opposite ends of a longitudinally adjustable strap element.

Still another object is to provide, in one form of the invention, means for adjusting the buttons into selected positions angularly spaced ninety degrees from each other, with a clasp loop being especially shaped to receive the button in either of said positions of the button, in a manner to place, if desired, additional tension upon the connecting strap, resulting in corresponding additional tension upon the sides and ends of the sheet tending to hold the sheet in proper position upon the mattress.

A further object of importance is to provide means of the character referred to that will be adapted to lie flat against the underside of the mattress when applied to a sheet, with the result that there will be no undesirable lumps, projections, or other formations upon the device that may tend to produce discomfort or, alternatively, tend to produce wear and damage to the sheets and mattress.

Still another object of importance is to provide a device of the character stated which will be adapted for use either on sheets of the type having sewed-in corner pockets, or, alternatively, so-called fiat, conventional sheets, without requiring modification or redesign of the device.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various ice.

novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure: I

Referring to the drawings in detail, the reference numeral 10 generally designates a mattress of conventional box type construction, to which has been applied a sheet In the illustrated example, the sheet is wholly conventional, being the flat type without corner pockets. This showing has been provided to illustrate the adaptability of the invention for application to sheets of this type, that may already be in use, with the application of the device having the effect of forming the sheet into a sheet having the characteristics of a contour sheet having said corner pockets. It will be understood, however, that the invention is equally well adapted for use upon contour sheets having pockets at their corners receiving the corners of the mattress. This, it is believed, will be fully obvious from the description to be provided hereinafter, and accordingly, a showing of the device on contour sheets having sewed-in pockets has not been provided.

The device constituting the present invention has been generally designated 14, and as shown in Fig. 1, is used in a set of four identical devices, each extending diagonally across a corner of the mattress and sheet, at the underside of the mattress.

To use the device, the sheet 12, along its sides 16, is

Since all the connecting devices 14 are identical to' each other, the description of one will suifice for all of them.

The connecting device 14 includes an elongated strap 24, which can be of elastic material if desired, although a nonelastic, strong, reinforced fabric could be used with equal facility.

The connecting strap 24, intermediate its ends, is passed through an adjusting buckle 26. This, as shown in Fig. 4, is in the form of a rectangular frame, and slidable longitudinally upon and extending transversely of the frame, adjacent the opposite ends thereof, are crosspieces 28, in the form of fiat sheets of metal material, the ends of which are rolled to provide sleeves 39 receiving the opposite sides of the frame of the buckle. On the edges of the crosspieces that face toward the opposite ends of the frame, there are formed teeth 32.

By reason of this construction, with the strap passed above the crosspieces and then under the ends of the frame as shown in Fig. 3, adjustments in the overall length of the strapcan be readily effected. For example, if the strap is to be at its maximum length, it will be adjusted to the full line position of Fig. 3, flat against the top surfaces of the crosspieces 28. If, however, the strap is to be shortened, the slidable elements 28 are shifted inwardly, causing the teeth 32 to disengage from the material of the strap. The strap is then lifted upwardly to the dotted line position of Fig. 3, after which the slide elements 28 are shifted once again toward the ends of the frame, causing the teeth 32 to bite into the strap material.

At its opposite ends, the strap 24 is folded upon itself as at 34, and the folded portion is stitched to the body part of the strap, thus to provide transversely extending sleeves receiving the inner ends 36 of a clasp 38. The clasp 38 is in the form of an elongated, closed frame, and as shown in Fig. 6, the inner end portion 36 of said frame merges at its ends into short side portions which in turn merge into inwardly directed crimps 40, said crimps merging into elongated, parallel side portions 42. Side portions 42 merge into inwardly directed offset parts of the sides of the frame, which in turn merge into parallel, straight extensions 44 of the side portions 42. The extensions 44 are spaced apart a substantially smaller distance than are the side portions 42, as will be noted from Fig. 6, and are integrally connected at the outer end of the clasp by an outer end portion 45.

An elongated rubber button 46 is formed with a peripheral flange 48, providing an overhang that overlies the extensions 44 and outer end portion 45 when the button is received in the slot-like space defined between the extensions 44 (see Fig. 6).

Downwardly facing male gripper snap fastener elements 50. are provided upon the longitudinal median of the rubber button or block 46, adjacent to the opposite ends of the block, and these are formed with flat heads 52 embedded in the material of the rubber block as shown in Fig. 5. The male fastener elements 50 are adapted to be detachably engaged in conventional female snap fastener elements 54 embedded in a short strap member 56 of either elastic or inelastic fabric material forming an extension of the strap 24. The strap member 56 is secured at one end to the strap 24 by the stitcl ing 35 forming the folded portion 34. The clasp 38 rests loosely on the surface of the strap.

In order to apply the connecting or tensioning device to a conventional sheet, the short strap members 56 carrying the bottoms or blocks 46 are inserted under the

adjacent portions

18 and 22 of the sheet 12?. adjacent the corners thereof as shown in Fig. l. The buttons or blocks bulge the material of the sheet upwardly therearound and the clasps 38, are swung downwardly so that their wide portions 42 envelope the bulged material over the buttons or blocks. The clasps 38 are then puIled longitudinally to bring the narrow portions 44 into gripping relation with the material at the sides of the buttons or blocks thereby detachably fastening the straps 24 m the heet When the connecting or tensioning devices are applied to the four corners of the sheet, tension will be exerted on the sheet along the lines extending diagonally across the corners of the sheet to hold the same properly tension'ed upon the mattress, without possibility of slippage of the sheet from the desired position.

The sheet may be suitably marked as shown at 55 in Fig. 1A to show the proper locations for attachment of the ends of the connecting devices.

The connecting or tensioning devices may readily be removed from the sheet to permit laundering of the sheet.

In the form of the invention shown in Figs. 7 and 8, means is provided for increasing the tension with which the sheet is stretched diagonally across the corners. In Fig. 7, the modified connecting device 14 includes a strap 24 identical to the first form of the invention. Said strap may or may not be provided with the buckle 26, as desired. Further, the sheet 12 is identical to the first form, as is the button 46 together with its male gripper fastener elements 550?. i

In this form of the invention, the clasp 38 is basically similar to the clasp 38. However, there is a difference in that the side portions 42 are spaced apart a greater distance than are the side portions 42. The strap-connected inner end portion of the frame of the clasp, however, is similar to the first form, including an end 36*- passing through the sleeve 34 of strap 24. The crimps 40 merge into the side portions 42 with the side portions 42 merging at their outer ends into offset portions that in turn merge into the extensions 44 connected by the outer end portion 45. The extensions 44 are of a length, and are spaced apart, similarly to the extensions 44.

The short strap 56 in this form of the invention, however, carries two pairs of opposed female snap fasteners 54*, 54 55, 55. One pair of

female elements

54, 54 is arranged identically to the pair of female elements 54, 5 4 of the first form of the invention, that is the elements are disposed longitudinally of the strap member 56*. The other pair of elements 55 55 however is aligned so that the elements are disposed in a line perpendicular to a straight line drawn between the elements 54*, 54 of the first pair, or along a line aligned with the longitudinal center of the strap 56 In other words, the several female elements are angularly spaced ninety degrees apart in a circular path drawn about the center point of the short strap 56*.

By reason of this arrangement, the button or block 46 can be adjusted to either of the positions shown in Figs. 7 or 8. For example, the block can be adjusted to the Fig. 7 position, in which it extends normally to the direction in which it extends in the first form of the invention, with the male gripper fastener elements being connected to the female elements 55. The button thus extends perpendicularly to the length of the strap 24. However, the side portions 42 are so spaced apart as to be engageable under the ends of the flange 48 of the button, with the inwardly directed oifsets at the outer ends of the side portions 42 also engaging under said flange.

This places the strap 24 under substantial tension, in effect reducing the distance between the points at which the device 14 is connected to the sheet.

If it is desired to increase this distance, one merely adjusts the button 46 to the Fig. 8 position, with the male gripper fastener elements, connected to the female ele ments 54 Now, the clasp is usable in the same manner as in the first form, that is, the button is received in the space between the extensions 44. It will be seen that this permits the clasp to be shifted to the right relative to the button, as compared to the clasp position of Fig. 7, and obviously, this has the effect of reducing the tension of the connecting strap 24, in effect increasing the distance between the points at which the device 14 is connected to the bed sheet.

In Fig. 9 another clasp device 60 is shown with a pair of corrugated ends 61 with a lock spring 62 thereover adapted to clamp the sheet 12 when the handles 63 of the cam members 64 are turned in the direction toward the ends of the spring 62.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
