2 Claims, 27 Drawing Figures PATENTED Aunzsms SM] 1 UP 7 PATENTED AUEZ 6 I975 LQMT PATENTEB AUBZBIQYS 390(1809 COVER SHEET FOR FITTING VARIOUS SHAPED MATTRESSES BACKGROUND OF THE INVENTION I. Field of the Invention The present invention relates to a cover-sheet for a mattress which can be entirely flattened to facilitate the washing, ironing, folding and storage thereof. This cover sheet may be utilized on mattresses of various widths and lengths.

II. Description of the Prior Art Present cover-sheets must correspond to the size of the bed with which they are to be utilized. This causes the manufacturer and the seller to manufacture or to have on hand sheets of many various sizes. When purchasing sheets the buyer must specify the size of the bed or beds for which the sheets are to be utilized. This requirement restricts the choice of sheets which may be purchased.

Fitted cover-sheets are also known for beds but these cover-sheets do not always fit perfectly due to the different thicknesses of the mattresses. Unavoidable folds and creases are often associated with these sheets.

SUMMARY OF THE INVENTION The purpose of the present invention is to create a cover-sheet fitting all sizes of mattresses. Due to a trapezoidal cutting, the sheet is also able to cover the mattress as well as the bolsters or the pillows without forming folds or creases.

The invention solves the above mentioned fold and crease problem by incorporating a crease free attaching system in the comers, or on a portion or all the periphery of absolutely flat sheets. This crease free attaching system enables transformation of these flat sheets into a fitted mattress cover by means of strands, elastics, or creasing ribbons.

This invention also contemplates the use of alternative fastening means in the comers of a flat, substantially trapezoidally shaped mattress cover-sheet to secure the sheet to the mattress. These fastening means include notched, slit, or specially shaped corners of the sheet that are provided with inserts of resilient cloth, or fastening strips known under the trademark of VEL- CRO, buttons, magnetic elements, or sewed hems with tie strings, etc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, the cover-sheet comprises a rectangular central portion 1 having the size as the top surface of the mattress, peripherial regions 2, 3, 4 and, 5 enabling the covering of the vertical sides of the mattress, and finally extensions 6, 7, 8, 9 which envelope the corners and extend beneath the lower portion of the mattress when the sheet is placed on said mattress. In the corners 10, ll, 12, 13 are found hem elements 10a, Ila, 12a, 13a which are used to stretch the sheet on the mattress or to pre-form the corners to ensure the perfect position thereof without folds or creases.

In FIG. 2, the cover-sheet comprises a central portion 20 having a rectangular shape taking the form of the mattress, but the extensions 21, 22 are widened towards the head of the bed. Extension 23 is also enlarged. This configuration allows the cover-sheet to envelop the mattress and either the bolster or the pillows, or simultaneously both elements. The remaining portion of the sheet is similar to that shown in FIG. 1 since are hem elements 24 are again disposed in the corners and are used to pre-form the sheet so that it fits on the mattress without any folds or creases.

FIG. 4 shows hems 25 placed in the corners of the sheet 20.

FIG. 4a shows the bottom part of the mattress when the sheet is placed on the mattress.

FIG. 5 shows a sheet 29 configured like the sheet in FIG. 2 to cover not only the mattress but also the bolster or the pillows or all three elements. However, additional cuts 30 are provided to reduce the thickness of the creases of the cloth when covering the mattress. These cuts can also be hemed. The hems 31, or similar elements, allow the sheet 29 to be installed on the bed.

FIGS. 5a and 5b show the installation of the sheet as viewed from beneath the mattress.

In FIG. 6, the sheet 32 comprises other cuts 33 placed in its comers. Sheet 32 is of a substantially trapezoidal shape and is also designed to cover, besides the mattress, the pillows, bolster or the both elements at the same time. Only the shape of the cuts 33 varies with respect to the cuts 30 of the sheet 29 of FIG. 5.

FIGS. 6a, 6b show, from beneath, how to attach the sheet of FIG. 6 to a mattress by means of seams or hems in the corner.

In FIG. 7, the sheet 34 has substantially the same trapezoidal shape as the sheet shown in FIG. 2. However, additional angle-cuts 35 are included. These can be sewed or provided with soft fastening elements as mentioned below.

FIGS. 7a, 7b show from beneath the sheet of FIG. 7 installed on a mattress. It is to be noticed that the sheet is held in its corners by resilient strips 36 or by hems 37 (FIG. 7).

FIG. 10 shows a slight variant of the sheet represented in FIG. 2. The corners of the sheet are sharp and near the edge of the sheet are disposed various attaching elements 38. For example, the attaching elements shown in FIG. 11 are button-holes and doublehead buttons. In FIG. 12 the attaching elements are adhesive strip of the type known commercially under the trade-mark VELCRO. With these VELCRO strips the sheet may be adjusted to fit snuggly over the mattress.

In FIG. 13, the corners of the sheet 39 are provided with fastening elements 40. These fastening elements may be strips of adhesive cloth known under the name VELCRO or others, or magnetic elements.

FIG. 14 shows the sheet 39 shown in FIG. 13 folded back to form a pocket.

In FIGS. 15 thru 20, foldings 43 of the sheet have been represented with various fastening elements in the corners or on the peripheral strips surrounding the central zone of the sheet, such as self adhesive strips, magnetic elements, buttons or others.
