AI Technical Summary

Technical Problem

Existing sheets for beds require multiple sizes and markings that shift due to shrinkage, complicating bed making and alignment, especially with varying mattress sizes and repeated drying processes.

Method used

A sheet with standardized marks placed 40-45 cm from the ends of the longer sides, near the shorter sides, allowing alignment with the mattress edges to simplify bed making.

Benefits of technology

Facilitates easy and accurate sheet placement on mattresses of varying sizes, reducing alignment time and eliminating the need for multiple sheet sizes and repressing due to shrinkage resistance.

Description

Technical Field

[0001] This invention relates to sheets.

Background Art

[0002] Conventionally, in hotels and the like where hundreds to thousands of beds are installed, various devices have been made to efficiently make the beds. In particular, when placing a sheet on a mattress, time is spent on alignment.

[0003] For example, Patent Document 1 discloses a sheet provided with marks at positions corresponding to the corners of a mattress. By using this sheet, if the sheet is placed on the mattress so that the mark on the sheet coincides with the corner of the mattress, the alignment of the sheet becomes easy.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The sheet described in Patent Document 1 needs to have marks provided on the sheet corresponding to the four corners of the mattress. It is necessary to provide marks corresponding to at least two corners on the diagonal line of the mattress. However, mattresses come in various sizes from single to queen. For this reason, the marks corresponding to the corners of the mattress need to be provided at different positions according to the size of the mattress, and it was necessary to prepare various sheets.

[0006] Furthermore, if the sheets undergo multiple final pressing and drying cycles, they shrink along their longer sides, causing the markings on the sheets to shift. This can prevent the markings from aligning with the corners of the mattress, potentially leading to extra time spent on bed making.

[0007] The objective of this invention is to provide a sheet that allows for easy bed making even after repeated finishing press drying. [Means for solving the problem]

[0008] The inventor focused on the fact that the finishing press drying process flows in the direction of the shorter side. They also noted that sheet sizes are standardized by JIS (Japanese Industrial Standards), and the width from the edge of the mattress to the longer side of the sheet is generally around 40-45 cm.

[0009] Therefore, the inventor placed a mark near the short side, where shrinkage is less likely to occur even after repeated finishing press drying. This suppresses misalignment of the mark, making it easy to make a bed even with sheets that have been repeatedly finished press dried.

[0010] Furthermore, these marks are placed on one of the longer sides of the sheet, 40-45 cm away from each end of the longer side, near the shorter sides. Therefore, by simply aligning the imaginary line connecting the two marks with the longer side of the mattress, the sheet can be placed straight on the mattress, making positioning easy. The invention derived from these findings is as follows:

[0011] (1) A sheet that is roughly rectangular in shape, characterized in that marks are provided on one of the longer sides of the sheet, in the area near each of the shorter sides, 40 to 45 cm away from each of the ends of the longer side. [Brief explanation of the drawing]

[0012] [Figure 1] Figure 1 shows an example of a sheet according to the present invention. [Modes for carrying out the invention]

[0013] The present invention will be described in detail below, but is not limited thereto. Furthermore, each embodiment can be combined in various ways.

[0014] Figure 1 shows an example of a sheet according to the present invention. As shown in Figure 1, the sheet 10 is composed of two long sides 13, the ends 11 of the long sides 13, two short sides 12, and two marks 14.

[0015] According to Figure 1, the two marks 14 are located in the vicinity of the short side 12, from arrow 16, which is 40 cm from the end 11 of the long side 13, to arrow 15, which is 45 cm from the end 11 of the long side 13. The distance from the marks 14 to the end 11 is a distance that can cover the side of a mattress (not shown), and is a generally standardized distance.

[0016] Furthermore, by aligning the imaginary line 14-1 connecting the two marks 14 with one of the longer sides of a mattress (not shown), the sheet can be easily positioned. Note that this imaginary line 14-1 allows for the positioning of the sheet 10 in the width direction, but it does not allow for the positioning of the sheet 10 in the length direction. However, regarding the length direction of the sheet 10, a typical bed has a headboard on the shorter side. Therefore, the shorter end of the sheet 10 can be tucked into the gap between the headboard and the mattress, and positioning the sheet 10 in the length direction is not necessarily required.

[0017] Mark 14 may also be provided at a position 40-45 cm away from the end of the other long side 13. In other words, a total of four marks 14 may be provided. This makes bed making even easier by aligning the two imaginary lines 14-1 with the long sides of the mattress.

[0018] Thus, the linen product according to this invention exhibits a soft texture due to the cotton pile, and the quick-drying and shape-recovering properties of the fabric eliminate the need for pressing. [Explanation of Symbols]

[0019] 10 Sheet, 11 Edge (of the long side), 12 Short side, 13 Long side, 14 Dummy line, 15 Arrow located 45 cm from edge 11 of the long side 13, 16 Arrow located 40 cm from the edge of the long side

Claims

[Claim 1] A sheet that is roughly rectangular in shape, characterized in that marks are provided on one of the longer sides of the sheet, in the vicinity of each of the shorter sides, 40 to 45 cm away from each of the ends of the longer side.
