[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-028061 Summary of the Invention [Problem to be solved by the invention]

[0004] When attaching or detaching a conventional sheet pad to a mattress, it is necessary to lift the four corners of the mattress one by one and then wrap or remove the rubber bands around the corners of the mattress, which places a heavy burden on the worker, especially when the mattress is large and heavy. Therefore, for people with weak strength, such as the elderly, conventional sheet pads inevitably require a long washing cycle, which is unhygienic.

[0005] The object of the present invention is to provide a mattress sheet pad that allows for easy removal and attachment of the top cloth. [Means for solving the problem]

[0006] The mattress sheet pad of the present invention comprises a rectangular top cloth that covers the top surface of the mattress and side cloths that cover the sides of the mattress, the side cloths having an upper opening that opens to the top side of the mattress and a lower opening that opens to the underside of the mattress, and the top cloth is removably connected to the side cloths by a full-circumference zipper structure provided between the entire periphery of the outer edge of the top cloth and the entire periphery of the top opening of the side cloths. [Effects of the Invention]

[0007] According to the mattress sheet pad of the present invention, it is possible to provide a mattress sheet pad in which the top cloth can be easily attached and detached. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 2 is an exploded perspective view of the mattress sheet pad according to the present embodiment, including the mattress. [Figure 2] 3 is an explanatory diagram of a zipper in the mattress sheet pad according to the present embodiment. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present invention will now be described with reference to the accompanying drawings. FIG. 1 shows an exploded perspective view of a mattress sheet pad 10 (hereinafter referred to as "sheet pad 10") according to this embodiment, and particularly includes a mattress 1. Because the mattress 1 is a pre-made product, a description of the mattress 1 will be omitted. For convenience, the upper side of the mattress 1 in FIG. 1 will be referred to as the "head side side," the lower side in FIG. 1 as the "foot side side," the right side in FIG. 1 as the "right side side," and the left side in FIG. 1 as the "left side side," and reference numerals will be omitted.

[0010] As shown in FIG. 1 or 2, the sheet pad 10 has a rectangular top cloth 11 that covers the top surface 2 of the mattress 1, side cloths 21 that cover the entire periphery of the side of the mattress 1, and a zipper 41 (full-periphery zipper structure) that separably connects the top cloth 11 and the side cloths 21. In this embodiment, the top cloth 11 is made of a polyester blend fiber that has excellent water absorption and quick-drying properties. The side cloth 21 is made of a knit material (synthetic fiber) that is highly stretchable. The zipper 41 is a full-periphery coil zipper that can separate a tape 43 on the top cloth 11 side from a tape 44 on the side cloth 21 side.

[0011] The side cloth 21 has a side 22 that covers the side surface on the head side of the mattress 1, a side 23 that covers the side surface on the right side of the mattress 1, a side 24 that covers the side surface on the foot side of the mattress 1, and a side 25 that covers the side surface on the left side of the mattress 1. The left-right orientation of the side cloth 21 relative to the mattress 1 is determined based on the position of the opening 42 of the zipper 41.

[0012] The side cloth 21 has an upper surface opening 27 that opens on the side of the upper surface 2 of the mattress 1 (hereinafter referred to as the "upper surface side of the mattress 1", the upper side in FIG. 1), and a lower surface opening 28 that opens on the side of the lower surface (reference numeral omitted) of the mattress 1 (hereinafter referred to as the "lower surface side of the mattress 1", the lower side in FIG. 1). The side cloth 21 has an elastic cord 30 that is provided along the entire periphery (hereinafter referred to as the "entire periphery") of the lower surface opening 28. By contracting the elastic cord 30, the peripheral portion 29 of the lower surface opening 28 of the side cloth 21 can be inserted (hooked) into the inside of the lower end of the mattress 1, and by stretching the elastic cord 29, the peripheral portion 29 of the lower surface opening 28 can be pulled out from the inside of the lower end of the mattress 1 to the outside.

[0013] The side surface cloth 21 has four (plural) rubber bands 31 that are hung over the four corners (reference numerals omitted) of the mattress 1. Each rubber band 31 is provided on the upper surface opening 27 side of the side surface cloth 21 so as to hang diagonally between adjacent side surfaces of the side surface cloth 21, i.e., between side surface 22 and side surface 23, between side surface 23 and side surface 24, between side surface 24 and side surface 25, and between side surface 25 and side surface 22.

[0014] The zipper 41 has an element 45 provided on tape 43 sewn along the entire periphery (entire circumference of the outer peripheral edge) of the top cloth 11, an element 46 provided on tape 44 sewn along the entire periphery of the upper opening 27 of the side cloth 21, and a slider 50 that engages or disengages the elements 45, 46. The zipper 41 has an opening 42 (starting point) located in the center of the left-right direction on the foot side of the mattress 1.

[0015] The sheet pad 10 has a molding 13 sewn along the entire periphery of the top cloth 11 and a molding 33 sewn along the entire periphery of the upper opening 27 of the side cloth 21. The zipper 41 including the slider 50 is covered by the molding 13 on the top cloth 11 side and the molding 33 on the side cloth 21 side so that it cannot be seen from the outside.

[0016] Next, the operation of this embodiment will be described. When the sheet pad 10 is attached to the mattress 1, like a typical box-type sheet pad, the mattress 1 is inserted into the sheet pad 10 from the opening 28 on the underside of the sheet pad 10 with the top cloth 11 and the side cloth 21 connected, and the sheet pad 10 covers the top surface 2 and the side surfaces of the mattress 1.

[0017] When the sheet pad 10 is attached to the mattress 1, each rubber band 31 of the side cloth 21 is hung diagonally over the corresponding corner of the mattress 1, and the peripheral edge 29 of the lower opening 28 of the side cloth 21 is inserted inside the lower end of the mattress 1 by the elastic force of the rubber cord 30 provided along the entire periphery of the lower opening 28 of the side cloth 21.

[0018] When removing the top cloth 11 of the sheet pad 10 attached to the mattress 1, the slider 50 of the zipper 41 is operated to release the interlocking of the elements 45, 46 over the entire periphery of the top surface opening 27 of the top cloth 11 and the side cloth 21, thereby making it possible to separate the top cloth 11 from the side cloth 21. On the other hand, when attaching the top cloth 11 to the side cloth 21 attached to the mattress 1, the slider 50 of the zipper 41 is operated to interlock the elements 45, 46 over the entire periphery of the top surface opening 27 of the top cloth 11 and the side cloth 21, thereby connecting the top cloth 11 to the side cloth 21.

[0019] When attaching or detaching a conventional sheet pad to or from a mattress, it is necessary to lift the four corners of the mattress one by one and then loop the rubber bands around or remove them from the corners of the mattress, which places a heavy burden on the worker, especially when the mattress is large and heavy. As a result, when using conventional sheet pads with weaker strength, such as elderly people, the washing cycle is inevitably longer, which is unhygienic.

[0020] In contrast, in this embodiment, the sheet pad 10 is configured so that the top cloth 11 is detachably connected to the side cloth 21 by a full-circumference zipper structure provided between the entire peripheral edge (the entire circumference of the outer peripheral edge) of the top cloth 11 and the entire peripheral edge of the upper opening 27 of the side cloth 21.

[0021] According to this embodiment, only the top cloth 11, which is interposed between the user of the mattress 1 and the upper surface 2 of the mattress 1 that supports the user, in other words, only the top cloth 11, which is more easily soiled than the side cloths 21, can be easily attached and detached from the side cloths 21. This eliminates the need to sequentially lift the four corners of the mattress when attaching and detaching the sheet pad 10, as is required with conventional sheet pads, and reduces the burden on the worker who attaches and detaches the sheet pad 10. As a result, even people with little strength, such as the elderly, can remove and frequently wash only the top cloth 11, which helps prevent the growth of dust mites, mold, and the like and maintains a comfortable sleeping environment.

[0022] In this embodiment, only the flat top cloth 11 can be separated from the side cloths 21 for washing, so that the drying time after washing can be significantly reduced compared to conventional box-type sheet pads, and the sheet pad 10 can be maintained in a clean condition.

[0023] In this embodiment, multiple rubber bands 31 provided at the upper opening 27 of the side cloth 21 are configured to be hung diagonally over the four corners of the mattress 1, so that even when the top cloth 11 is detached from the side cloth 21, it is possible to prevent the side cloth 21 from slipping off the mattress 1, thereby ensuring the aesthetic appearance of the room in which the mattress 1 is installed.

[0024] In this embodiment, the zipper 41 (full-circumference zipper structure) is covered with the molding portion 13 on the top cloth 11 side and the molding portion 33 on the side cloth 21 side, so that the zipper 41 is not visible from the outside, thereby ensuring the aesthetic appearance of the mattress 1 when the sheet pad 10 is attached.

[0025] In this embodiment, opening 42 of zipper 41 is located on the foot side of sheet pad 10, so slider 50 of zipper 41 can be stored in a position that does not interfere with sleep when sheet pad 10 is attached to mattress 1. Note that opening 42 of zipper 41 may be located in any position that does not interfere with sleep. [Explanation of symbols]
