DETAILED DESCRIPTION OF THE INVENTION

(17) A mattress protector 20 according to a first embodiment of the present invention is shown in FIGS. 2 through 7 of the drawings and is used to securely wrap a mattress 22, particularly a commercially available mattress 22 with a distinct thickness (height) for flatness of a bed surface and the mattress protector 20 neither slippery nor loose.

(18) The mattress protector 20 includes an upper layer (bed surface layer) 24, a lower layer 26, and a side layer 28 linking edges of the upper and lower layers 24 and 26. Preferably, the upper and lower layers 24 and 26 are made of fabrics. The side layer 28 includes a top periphery 30 and a bottom periphery 32 spaced from the top periphery 30 in a height direction of the side layer 28, and the top and bottom peripheries 30 and 32 respectively abut the upper and lower layers 24 and 26. The mattress protector 20 further includes an opening 34 from which the mattress 22 can be placed in the mattress protector 20. At the opening 34 is provided with a zipper 36 by which the opening 34 is controllably opened or closed (FIG. 3). In this embodiment, the opening 34 is revealed along the bottom periphery 32 of the side layer 28; in another embodiment, the opening 34 can be provided along the top periphery 30 of the side layer 28. Furthermore, a protrudent edge portion 38 is designed along the circumference of the side layer 28 and between the top periphery 30 and the bottom periphery 32 of the side layer 28. In this embodiment, the side layer 28 is partially folded and stitched for development of the protrudent edge portion 38, as shown in FIG. 6.

(19) The mattress protector 20 further includes a plurality of first joint members 40. In this embodiment, each of the first joint members 40 is a fastener with a plurality of hook portions 42 at both sides thereof (see FIG. 5, which illustrates a fastener with hook sides at the front and back). An outer surface of the side layer 28 is provided with a plurality of loop portions 44 which correspondingly combine the hook portions 42, that is, the side layer 28 consists of fasteners with loop sides. With the hook portions 42 and the loop portions 44 fastening each other, each of the first joint members 40 can be detachably engaged on the side layer 28. In a feasible embodiment, each of the first joint members 40 is a fastener with loop portions at two sides thereof, and the side layer 28 consists of fasteners with hook portions, so that each of the first joint members 40 is detachably engaged on the side layer 28.

(20) The first joint members 40 spaced from one another are deployed along a circumference of the side layer 28 and located above the protrudent edge portion 38. Preferably, the first joint members 40 are accordant to the side layer 28 in height. Further, each of the first joint members 40 is spaced from the top periphery 30 (or the bottom periphery 32) of the side layer 28 by a distinct distance, so that a section of the side layer 28 between the first joint members 40 and the top periphery 30 (or the bottom periphery 32) of the side layer 28 can be relatively folded for development of a first folding portion 46 and a second folding portion 48 (see FIG. 7). With the hook portions 42 on an outer side of each first joint member 40 on the first folding portion 46 joining the loop portions 44 of the second folding portion 48, the first and second folding portions 46 and 48 are connected to each other. In a feasible embodiment, the first joint members 40 are located below the protrudent edge portion 38. However, the first joint members 40 deployed above the protrudent edge portion 38 avoids a shift of the upper layer 24 of the mattress protector 20 and stabilizes the mattress protector 20 to securely wrap the mattress 22 when the section of the side layer 28 between the first joint members 40 and the top periphery 30 is double folded.

(21) The present invention further provides a method to wrap a mattress, which includes providing the mattress protector 20 and placing a mattress 22 in the mattress protector 20 with a top surface 50, a bottom surface 52 and a peripheral surface 54 of the mattress 22 respectively wrapped by the upper layer 24, the lower layer 26 and the side layer 28 of the mattress protector 20, and with four corners of the mattress protector 20 aligned with four corners of the mattress 22 (FIG. 6). Then, a section of the side layer 28 between the first joint members 40 and the top periphery 30 in the height direction of the side layer 28 are relatively folded for development of the first and second folding portions 46 and 48, both of which can be securely fixed to each other with the first joint members 40 at the first folding portion 46 joining the second folding portion 48 (FIG. 7). In this method, the height of the side layer 28 of the mattress protector 20 is selected to match a commercially available mattress with a larger thickness. As such, the mattress protector 20 is able to tightly wrap either the mattress 22 having a corresponding thickness or another thinner mattress for secure wrapping effect.

(22) The mattress protector 20 of the present invention, which matches a mattress's distinct thickness with the height of the side layer 28 adjusted, is characteristic of secure wrapping effect by which the mattress protector 20 covered on the mattress 22 keeps a smooth bed surface neither slippery nor loose. Moreover, the protrudent edge portion 38 contributes to double folding and linking the first and second folding portions 46, 48 conveniently. Specifically, the protrudent edge portion 38, which is a benchmark to double fold the first and second folding portions 46 and 48, can be gripped by a user double folding the first and second folding portions 46, 48 for easy adjustment of the side layer 28 in height. Furthermore, when the mattress protector 20 needs to be cleaned in a washing machine, each first joint member 40 (a fastener with a plurality of hook portions 42 at both sides), which is randomly and easily separated from as well as flexibly and repeatedly attached to the side layer 28, can be removed, and fabrics of the upper layer 24 or the lower layer 26 are not wound by a hook side on the two-sided fastener for easy cleaning.

(23) FIGS. 8 through 10 illustrate a mattress protector 20 in a second embodiment of the present invention. In this embodiment, a plurality of second joint members 56 is provided on an outer surface of the side layer 28 and above each first joint member 40, so that one of the second joint members 56 can be selected to join a corresponding first joint member 40. Each of the first joint members 40 and each of the second joint members 56 are a button-like male fastener and a female fastener with a buttonhole 57, respectively. Each first joint member 40 and a corresponding second joint member 56 will fasten each other to fix the first and second folding portions 46 and 48 which are developed with a section of the side layer 28 between the first joint members 40 and the top periphery 30 double folded. In addition, the side layer 28 of the mattress protector 20 in this embodiment is made of but not limited to fastening fabrics.

(24) FIG. 11 illustrates a mattress protector 20 in a third embodiment of the present invention. In this embodiment, each of the first joint members 40 and each of the second joint members 56 are a hook-like male fastener and a female fastener with a buttonhole 57, respectively. FIG. 12 illustrates a mattress protector 20 in a fourth embodiment of the present invention. In this embodiment, each of the second joint members 56 and each of the first joint members 40 are a button-like male fastener and a female fastener with a buttonhole 57, respectively. In another embodiment, the first and second joint members 40 and 56 can be other types of male and female fasteners or can be magnetic members joining each other by magnetism. FIG. 13 illustrates a mattress protector 20 in a fifth embodiment of the present invention. In this embodiment, the side layer 28 is provided with no protrudent edge portion 38.

(25) FIG. 14 illustrates the mattress protector 20 of the present invention which is covered with a sanitary mat 58. A periphery of the sanitary mat 58 is provided with a plurality of spaced female fasteners 60 (fasteners with loop sides) and is integrated with the side layer 28 of the mattress protector 20 by a plurality of male fasteners (each of which is a fastener with hook sides at the front and back), so that the sanitary mat 58 is detachably attached to the mattress protector 20.

(26) FIG. 15 illustrates the mattress protector 20 of the present invention which matches the sanitary mat 58, a bedspread 64, and a bed skirt 68. The bedspread 64, which is provided with a plurality of spaced female fasteners 65 (fasteners with loop sides) along an internal periphery thereof, is detachably attached to the sanitary mat 58 with a plurality of spaced male fastener 66 (each of which is a fastener with hook sides at the front and back) joining the female fasteners 65 on the bedspread 64 and the female fasteners 60 on the sanitary mat 58. Furthermore, the bed skirt 68, which is provided with a female fastener 70 around an upper periphery thereof, is integrated with the side layer 28 of the mattress protector 20 by a plurality of male fasteners 72, so that the bed skirt 68 is detachably attached to the mattress protector 20 underneath. As such, the side layer 28 of the mattress protector 20 accordant to the thickness of a mattress for adjustment in height allows the sanitary mat 58, the bedspread 64 and the bed skirt 68, all of which rely on two-sided male fasteners detachably attached to the side layer 28, to be further added and to be removed and cleaned or installed without lifting the mattress for easy assembly and disassembly.

(27) The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
