[0013] The bedding pad according to each embodiment of the present invention will be described below with reference to each drawing. In the following description, the up-down, left-right, and front-back directions (directions orthogonal to each other) relating to the bedding pad are as shown in FIG. 1 and the like. Each of these directions is merely defined for convenience such that the thickness direction of the bedding pad corresponds to the up-down direction.

[0014] 1. First Embodiment First, the first embodiment will be described. FIG. 1 is a schematic perspective view of each element constituting the bedding pad 1 according to the first embodiment. FIG. 2 is a more specific perspective view of each element constituting the bedding pad 1. The bedding pad 1 comprises an upper pad 10 and a lower pad 20. In the upper pad 10, an upper fastener 31 (an example of the "upper engaging portion" according to the present invention) is provided on an upper pad main body 10a. In the lower pad 20, a lower fastener 32 (an example of the "lower engaging portion" according to the present invention) is provided on a lower pad main body 20a.

[0015] The upper zipper 31 and the lower zipper 32 are a pair of zippers 30. When the upper zipper 31 and the lower zipper 32 engage, the upper pad 10 and the lower pad 20 are joined together, as shown in Figure 3, and the bedding pad 1 is completed. By completely disengaging the upper zipper 31 and the lower zipper 32, the upper pad 10 and the lower pad 20 are separated. In this embodiment, open zippers are used as the pair of zippers 30.

[0016] The upper zipper 31 is positioned along the entire circumference of the upper pad 10 (upper pad body 10a) when viewed from above, and the lower zipper 32 is positioned along the entire circumference of the lower pad 20 (lower pad body 20a) when viewed from above. These zippers 31 and 32 are positioned so as to overlap when viewed from above, and their starting and ending points are located at the same position when viewed from above (in the example shown in Figure 2, the central part of the rear side of each pad 10 and 20). When these zippers 31 and 32 are fully engaged, it is possible to join the upper pad 10 and the lower pad 20 around the entire circumference of the bedding pad 1.

[0017] The bedding pad 1 is provided with a pair of zippers 30, which are an upper zipper 31 and a lower zipper 32. The bedding pad 1 is joined together by the pair of zippers 30 so that the upper pad 10 and the lower pad 20 overlap vertically, and is used by placing it on the bedding in which the user lies. The bedding pad 1 is used by placing it on the bedding in which the user lies, such as a mattress, bed mattress, or futon, and is basically used so that the front-to-back direction (longitudinal direction) of the bedding pad 1 coincides with the direction of the user's height. By placing the bedding pad 1 on such bedding, the user can obtain a more comfortable sleeping experience.

[0018] Furthermore, the pair of zippers 30 allows the upper pad 10 and the lower pad 20 to be switched between the joined state and the separated state described above. By separating the upper pad 10 and the lower pad 20, it is possible to reduce the thickness of the bedding pad 1. As a result, compared to the bedding pad 1 in the joined state, which is thick and bulky, it becomes easier to wash, for example, in a household washing machine.

[0019] Figure 4 is a perspective view of the upper pad 10, and Figure 5 is a perspective view of the lower pad 20. Both the upper pad body 10a and the lower pad body 20a are substantially sheet-like in shape with the thickness in the vertical direction, and are rectangular in shape (same shape and size) with the longitudinal direction in the front-to-back direction and the width in the left-to-right direction when viewed from above (viewed from above). In this embodiment, the upper pad 10 and the lower pad 20 have a size of 1960 mm in the front-to-back direction and a size of 970 mm in the left-to-right direction.

[0020] Each of the upper pad body 10a and the lower pad body 20a is formed by evenly distributing cotton CT between the outer fabric and the lining (upper and lower fabrics) and sewing the outer fabric and the lining together (i.e., quilting is applied). In addition, a double knit fabric may be used for one or both of the upper pad body 10a and the lower pad body 20a, and piping may be applied to the outer edge when viewed from above.

[0021] Furthermore, the quilting creates seams (quilting pattern) 11 on the upper pad body 10a and seams 21 on the lower pad body 20a. The seams 11 on the upper pad body 10a consist of multiple straight first seams 11a (sewn parallel to the left-right direction) extending in the front-back direction and multiple straight second seams 11b (sewn parallel to the front-back direction) extending in the left-right direction. Each of the first seams 11a is formed at a predetermined interval V1 in the left-right direction, and each of the second seams 11b is formed at a predetermined interval V2 in the front-back direction.

[0022] The seams 21 of the lower pad body 20a consist of multiple linear third seams 21a (sewns provided parallel to the left-right direction) extending in the front-back direction, and multiple linear fourth seams 21b (sewns provided parallel to the front-back direction) extending in the left-right direction. Each of the third seams 21a is formed at a predetermined interval V3 in the left-right direction, and each of the fourth seams 21b is formed at a predetermined interval V4 in the front-back direction.

[0023] Regarding the spacing of the seams as described above, the spacing of the lower pad body 20a is narrower than that of the upper pad body 10a. Specifically, the spacing V3 of each third seam 21a is narrower than the spacing V1 of each first seam 11a, and the spacing V4 of each fourth seam 21b is narrower than the spacing V2 of each second seam 11b.

[0024] Thus, the lower pad body 20a is designed with relatively fine quilting stitches to minimize shifting of the cotton inside. On the other hand, the upper pad body 10a, which is positioned closer to the user, is designed with wider spacing between quilting stitches compared to the lower pad body 20a to minimize shifting of the cotton inside while still providing a soft and fluffy feel.

[0025] In this embodiment, granular cotton is used as the cotton CT1 in the upper pad body 10a, and compressed cotton is used as the cotton CT2 in the lower pad body 20a. In this way, the cotton CT1 used in the upper pad body 10a is softer than the cotton CT2 used in the lower pad body 20a. For this reason, the upper pad body 10a, which is positioned closer to the user, is designed to provide a soft and fluffy feel, while the lower pad body 20a is designed to prevent the cotton CT2 from flattening and to minimize the feeling of bottoming out. Sheet-shaped cotton is used as the cotton CT2 in the lower pad body 20a. The cotton CT2 is formed by compression and is designed to have a soft, flattened feel from the start, so that it does not flatten out with use.

[0026] Furthermore, it is desirable that the surfaces of the upper pad 10 and the lower pad 20 that come into contact vertically (i.e., the lower surface of the upper pad body 10a and the upper surface of the lower pad body 20a) are designed to be resistant to slipping against each other. A friction-inducing portion may be formed on part or all of the surface of the upper pad 10 that comes into contact with the lower pad 20 (the lower surface of the upper pad body 10a). Similarly, a friction-inducing portion may be formed on part or all of the surface of the lower pad 20 that comes into contact with the upper pad 10 (the upper surface of the lower pad body 20a). For example, the friction-inducing portion may be hook-and-loop fasteners, etc. Alternatively, the lower surface of the upper pad body 10a may be made to appear napped. Alternatively, the upper surface of the lower pad body 20a may also be made to appear napped. It is desirable that the napped portion on the lower surface of the upper pad body 10a and the napped portion on the upper surface of the lower pad body 20a intertwine so that the contacting surfaces are resistant to slipping in a direction perpendicular to the vertical direction. This minimizes the impact on sleeping comfort caused by the upper pad 10 and lower pad 20 sliding.

[0027] Furthermore, as a connecting part that allows the upper pad 10 and the lower pad 20 to be switched between a joined state and a separated state, in the example of the first embodiment, a pair of zippers 30, consisting of an upper zipper 31 and a lower zipper 32, is adopted. However, other forms may be adopted instead of (or in conjunction with) the zippers 30. For example, a form using buttons (a button is provided on one of both pads 10, 20, and a hole into which the button can be fitted is provided on the other), a form using hook-and-loop fasteners (hook-and-loop fasteners that can adhere to each other are provided on both pads 10, 20), or a form using strings (a string is provided on each of the pads 10, 20, and the two pads 10, 20 are joined by tying the strings together). Note that the upper pad 10 and the lower pad 20 can be swapped up and down according to the user's preference. For example, the upper pad 10 and the lower pad 20 may be combined by placing the lower pad 20 on top of the upper pad 10 and connecting the upper zipper 31 and the lower zipper 32.

[0028] Furthermore, when adopting the configuration using hook-and-loop fasteners as the joining parts described above, the hook-and-loop fastener disclosed in Japanese Patent Application Publication No. 2020-120918 (a hook-and-loop fastener having a first fabric having a loop fiber layer and a second fabric having a hook fiber layer) may be used as the hook-and-loop fastener. That is, the first fabric may be provided on one of the upper pad 10 and the lower pad, and the second fabric may be provided on the other.

[0029] In this hook-and-loop fastener, the loop fiber layer is composed of multiple loop fibers formed from a first false-twist crimped pile yarn, and the hook fiber layer is composed of multiple hook fibers formed from a second false-twist crimped pile yarn. The first false-twist crimped pile yarn is an untwisted false-twist crimped pile yarn made by false-twisting bundles of resin fibers with a single filament fineness of 0.15 dtex or more and 0.7 dtex or less under the condition of a false-twist coefficient of 20,000 to 32,000, and the second false-twist crimped pile yarn is an untwisted false-twist crimped pile yarn made by false-twisting bundles of resin fibers with a single filament fineness of 1.5 dtex or more and 3.8 dtex or less under the condition of a false-twist coefficient of 20,000 to 32,000. In this hook-and-loop fastener, the first fabric and the second fabric are joined by the engagement of the loop fibers and the hook fibers.

[0030] 2. Second Embodiment Next, a second embodiment will be described. The second embodiment is basically the same as the first embodiment, except that a cover portion is provided and related points. In the following description, emphasis will be placed on explaining the differences from the first embodiment, and explanations of points common to the first embodiment may be omitted.

[0031] In the second embodiment, the lower pad 20 is provided with a cover portion that covers the entire circumference of the side surface of the upper pad 10 (upper pad body 10a). Figure 6 is a schematic perspective view of each element constituting the bedding pad 1 with such a cover portion. Figure 7 is a schematic cross-sectional view of the lower pad 20 shown in Figure 6 when it is cut by a plane perpendicular to the front-to-back direction near the center in the front-to-back direction.

[0032] The lower pad 20 shown in Figure 6 has a form in which a cover portion 22 made of fabric is attached to the lower pad body 20a. The cover portion 22 is attached, for example, by stitching, to the entire circumference of the lower surface of the lower pad body 20a (the area indicated by α in Figure 7), and extends upward by a predetermined amount from this entire circumference (to the area indicated by β in Figure 7). Furthermore, the cover portion 22 extends inward by a predetermined amount from the area indicated by β in Figure 7 in the left / right or front / back direction (to the area indicated by γ in Figure 7).

[0033] The cover portion 22 formed in this manner covers the entire circumference of the side of the upper pad 10 (the upper pad 10 joined to the lower pad 20 by a pair of zippers 30) at the position indicated by the dashed line in Figure 7. This makes it possible to hide the pair of zippers 30 with the cover portion 22, allowing the joined bedding pad 1 to appear more integrated and improving the design. In this embodiment, the cover portion covers the entire circumference of the side of the upper pad 10, as well as the vicinity of the entire edge on the upper surface of the upper pad 10.

[0034] 3. Third Embodiment Next, a third embodiment will be described. The third embodiment is basically the same as the first embodiment, except that a housing section is provided and related points. In the following description, emphasis will be placed on explaining the differences from the first embodiment, and explanations of points common to the first embodiment may be omitted.

[0035] In the bedding pad of the third embodiment, a bag-shaped storage section is provided on one of the upper pad 10 and the lower pad 20 to accommodate the other, as a joint that allows the upper pad 10 and the lower pad 20 to be switched between a joined state and a separated state. Figure 8 is a schematic perspective view of each element constituting the bedding pad 1 with such a storage section.

[0036] The lower pad 20 shown in Figure 8 has a configuration in which a storage section 23 made of fabric is provided on the upper side of the lower pad body 20a. More specifically, the storage section 23 has a side portion 23a that extends upward from the outer edge of the upper surface of the lower pad body 20a, excluding the right side (i.e., the front side, left side, and rear side), and an upper surface portion 23b that is positioned opposite the upper surface of the lower pad body 20a and connects with the entire upper edge of the side portion 23a. In this way, the storage section 23, together with the upper surface of the lower pad body 20a, forms a bag shape. An opening Z is provided on the right side of this bag-shaped storage section 23.

[0037] Therefore, as shown by the dashed arrow in Figure 8, the upper pad 10 can be easily inserted into and removed from the storage section 23 through the opening Z. By storing the upper pad 10 inside the storage section 23, the bedding pad 1 becomes a joined state with the upper pad 10 and the lower pad 20 connected. On the other hand, by removing the upper pad 10 from inside the storage section 23, the bedding pad 1 becomes a separated state with the upper pad 10 and the lower pad 20 connected. In this embodiment, since the storage section 23 serves as the connecting part, the installation of a pair of zippers 30 is omitted.

[0038] Thus, the storage section 23 functions as a joint that allows the upper pad 10 and the lower pad 20 to be switched between a joined state and a separated state. The shape and size of the storage section 23 are appropriately set so that the upper pad 10 fits inside the storage section 23. In the example shown in Figure 8, the opening Z of the storage section 23 is provided on the right side, but the opening Z may be provided on the left side, front side, or rear side. The opening Z may also be openable and closable. For example, a fastener, button, hook-and-loop fastener or other attachment / detachment member may be provided at the opening Z. In addition, multiple pads may be stacked and stored in this storage section 23. By selectively stacking and storing multiple pads in this way, the user can obtain a level of softness and bottoming-out sensation that suits their preference.

[0039] Furthermore, in the example shown in Figure 8, a storage section for the upper pad 10 is provided in the lower pad 20, but instead, a storage section for the lower pad 20 may be provided in the upper pad 10. In this case, the storage section can be provided on the lower side of the upper pad body 10a. In this case, compared to the case where the storage section is provided in the lower pad 20 (where the relatively soft upper pad 10 is inserted into and removed from the storage section), the relatively hard lower pad 20 will be inserted into and removed from the storage section, making the insertion and removal process easier.

[0040] 4. Fourth Embodiment Next, the fourth embodiment will be described. In the following description, emphasis will be placed on explaining the differences from the first embodiment, and explanations of points common to the first embodiment may be omitted.

[0041] Figure 9 is a front view of the basic form of the bedding pad 1 (cushion body) according to the fourth embodiment. In the basic form of the bedding pad 1, the upper pad 10 and the lower pad 20 are joined together by a zipper 30 so that they overlap vertically. Figure 10 is a left side view of the basic form of the bedding pad 1. Figure 11 is a right side view of the basic form of the bedding pad 1. Figure 12 is a top view of the basic form of the bedding pad 1. The bottom view of the basic form of the bedding pad 1 is shown symmetrically to the top view shown in Figure 12. The back view of the basic form of the bedding pad 1 is shown symmetrically to the front view shown in Figure 9.

[0042] In its basic form, the bedding pad 1 consists of an upper pad 10 and a lower pad 20 positioned below it, connected by a zipper 30 that is completely closed. The zipper 30 extends around the entire circumference of the side of the bedding pad 1. By moving the pull tab 30a to open the zipper 30, the upper pad 10 and the lower pad 20 can be separated at the opened portion.

[0043] When the zipper 30 is fully opened, the upper pad 10 and the lower pad 20 are completely separated. However, by moving the pull tab 30a as shown by the dashed arrow in the reference diagram (a diagram with the same viewpoint as the plan view) in Figure 13, the zipper 30 is opened except for a part of the right side (the part indicated by α in Figure 13). In this state, when the upper pad 10 is pulled upward, the upper pad 10 rotates around the extended part of the zipper 30 on the right side as an axis. In this way, the bedding pad 1 changes from its basic form (the form shown in Figure 9, etc.) to the modified form (the form shown in Figures 14 to 18, described later) based on the function of the bedding pad 1.

[0044] Figure 14 is a front view of the modified bedding pad 1. Figure 15 is a left side view of the modified bedding pad 1. Figure 16 is a right side view of the modified bedding pad 1. Figure 17 is a top view of the modified bedding pad 1. Figure 18 is a bottom view of the modified bedding pad 1. The rear view of the modified bedding pad 1 is shown symmetrically to the front view shown in Figure 14. By modifying the bedding pad 1 in this way, the upper pad 10 and the lower pad 20 are partially connected, while the inside of the bedding pad 1 is exposed, allowing for visual inspection and other checks.

[0045] 5. Others The bedding pad 1 of each embodiment described above is a bedding pad that is used by placing it on the bedding on which the user lies, with the upper pad 10 and the lower pad 20 joined together by a joint so that they overlap vertically. The joint allows the upper pad 10 and the lower pad 20 to be switched between the joined state and a separated state.

[0046] In the first, second, and fourth embodiments, the joint has a pair of fasteners 30 consisting of an upper fastener 31 provided on the upper pad 10 and a lower fastener 32 provided on the lower pad 20, and the upper pad 10 and the lower pad 20 are joined together when the upper fastener 31 and the lower fastener 32 engage. On the other hand, in the third embodiment, the joint is a storage section. In the third embodiment, this storage section is provided on the lower pad 20, but it may be provided on the upper pad instead of the lower pad. In other words, the joint is a bag-shaped storage section provided on one of the upper pad 10 and the lower pad 20 that can accommodate the other. When the other is accommodated in the storage section, the upper pad 10 and the lower pad 20 are joined together.

[0047] It should be noted that the above embodiments are illustrative in all respects and not restrictive. The technical scope of the present invention is indicated by the claims rather than by the above descriptions of embodiments, and should be understood to include all modifications that fall within the meaning and scope equivalent to the claims.
