[0002] The present invention relates to a bedding pad which is laid on bedding to be used.BACKGROUND ART

[0003] Conventionally, bedding pads have been proposed that are laid on bedding, such as a mattress, a bed mattress and a futon mattress, on which a user lies, and are used. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-217670) discloses a bed pad which is laid on the mattress of a bed, and in which a waterproof layer is provided on the mattress opposite surface of a bed pad body formed by integrating a side fabric and batting through a quilting process.

[0004] In general, in order to realize a bedding pad for sleeping comfort, it is needed to provide a thickness which can ensure adequate cushioning and the like. However, since the bedding pad having such a thickness is bulky, for example, it is likely that the bedding pad cannot be easily washed in a household washing machine.

[0005] The present invention provides a bedding pad which ensures sleeping comfort and can be, for example, more easily washed in a household washing machine.SUMMARY

[0030] A bedding pad according to each of embodiments of the present invention will be described below with reference to drawings. An up / down direction, a left / right direction and a forward / backward direction (which are orthogonal to each other) related to the bedding pad in the following description are as shown in FIG. 1 and the like. These directions are determined for convenience such that the thickness direction of the bedding pad is the up / down direction.1. First Embodiment

[0031] A first embodiment will first be described. FIG. 1 is a schematic perspective view of elements of a bedding pad 1 according to the first embodiment. FIG. 2 is a more specific perspective view of the elements of the bedding pad 1. The bedding pad 1 includes an upper pad 10 and a lower pad 20. In the upper pad 10, an upper fastener 31 (an example of an “upper engagement portion” in the present invention) is provided on an upper pad body 10a. In the lower pad 20, a lower fastener 32 (an example of a “lower engagement portion” in the present invention) is provided on a lower pad body 20a.

[0032] The upper fastener 31 and the lower fastener 32 are a pair of fasteners 30, and the upper fastener 31 engages with the lower fastener 32 such that the upper pad 10 and the lower pad 20 are brought into a joined state as shown in FIG. 3, with the result that the bedding pad 1 is completed. The engagement of the upper fastener 31 and the lower fastener 32 is completely released, and thus the upper pad 10 and the lower pad 20 are brought into a separated state. In the example of the present embodiment, open fasteners are adopted as the pair of fasteners 30.

[0033] The upper fastener 31 is disposed along the entire outer edge of the upper pad 10 (upper pad body 10a) when the upper pad 10 is viewed from above, and the lower fastener 32 is disposed along the entire outer edge of the lower pad 20 (lower pad body 20a) when the lower pad 20 is viewed from above. These fasteners 31 and 32 are provided such that they are overlaid on each other when viewed from above, and a start point and an end point are provided in the same position (in an example shown in FIG. 2, a center portion on the back side of each of the pads 10 and 20) when the fasteners 31 and 32 are viewed from above. These fasteners 31 and 32 are caused to completely engage with each other, and thus the upper pad 10 and the lower pad 20 can be joined over the entire periphery of the bedding pad 1.

[0034] As described above, in the bedding pad 1, the pair of fasteners 30 which are the upper fastener 31 and the lower fastener 32 are provided. The bedding pad 1 is brought into the joined state where the upper pad 10 and the lower pad 20 are joined with the pair of fasteners 30 to be vertically overlaid on each other, and is laid on bedding on which a user lies to be used. The bedding pad 1 is laid on the bedding, such as a mattress, a bed mattress or a futon mattress, on which the user lies, and is basically used such that the forward / backward direction (longitudinal direction) of the bedding pad 1 coincides with the height direction of the user. The bedding pad 1 is laid on the bedding as described above, and thus the user can obtain better sleeping comfort.

[0035] The pair of fasteners 30 can switch the upper pad 10 and the lower pad 20 between the joined state and the separated state described above. The upper pad 10 and the lower pad 20 are brought into the separated state, and thus it is possible to decrease the thickness of the bedding pad 1. In this way, as compared with the bedding pad 1 in the joined state which is so thick as to be bulky, the upper pad 10 and the lower pad 20 in the separated state can, for example, easily washed in a household washing machine.

[0036] FIG. 4 is a perspective view of the upper pad 10, and FIG. 5 is a perspective view of the lower pad 20. Each of the upper pad body 10a and the lower pad body 20a is substantially sheet-shaped with the up / down direction being the thickness direction, and is rectangular (in the shape of a rectangle having the same shape and size) with the forward / backward direction being the longitudinal direction and the left / right direction being the width direction when they are viewed from above (viewed from the upper side). In the upper pad 10 and the lower pad 20 in the example of the present embodiment, the size in the forward / backward direction is 1960 mm, and the size in the left / right direction is 970 mm.

[0037] Each of the upper pad body 10a and the lower pad body 20a is formed by uniformly disposing cotton CT between an outer fabric and an inner fabric (upper and lower fabrics) and sewing the outer fabric and the inner fabric together (in other words, each of the upper pad body 10a and the lower pad body 20a is quilted). In one or both of the upper pad body 10a and the lower pad body 20a, a double knit fabric may be adopted, and piping treatment may be applied to the outer edge when they are viewed from above.

[0038] The quilting described above is performed, and thus stitches (quilting pattern) 11 are formed in the upper pad body 10a, and stitches 21 are formed in the lower pad body 20a. The stitches 11 in the upper pad body 10a include multiple linear first stitches 11a extending in the forward / backward direction (stitches provided parallel to the left / right direction) and multiple linear second stitches 11b extending in the left / right direction (stitches provided parallel to the forward / backward direction). The first stitches 11a are formed at predetermined intervals V1 in the left / right direction, and the second stitches 11b are formed at predetermined intervals V2 in the forward / backward direction.

[0039] The stitches 21 in the lower pad body 20a include multiple linear third stitches 21a extending in the forward / backward direction (stitches provided parallel to the left / right direction) and multiple linear fourth stitches 21b extending in the left / right direction (stitches provided parallel to the forward / backward direction). The third stitches 21a are formed at predetermined intervals V3 in the left / right direction, and the fourth stitches 21b are formed at predetermined intervals V4 in the forward / backward direction.

[0040] The intervals of the stitches in the upper pad body 10a are shorter than the intervals of the stitches in the lower pad body 20a. In other words, the intervals V3 of the third stitches 21a are shorter than the intervals V1 of the first stitches 11a, and the intervals V4 of the fourth stitches 21b are shorter than the intervals V2 of the second stitches 11b.

[0041] As described above, in the lower pad body 20a, the stitches of the quilting are formed relatively finely to minimize the displacement of the cotton inside and the like. On the other hand, in the upper pad body 10a disposed closer to the user, while the displacement of the cotton inside and the like are being suppressed by the quilting, the intervals of the stitches in the quilting are made longer than in the lower pad body 20a such that a soft and fluffy feel is obtained.

[0042] In the present embodiment, as the cotton CT1 used in the upper pad body 10a, granular cotton is adopted, and as the cotton CT2 used in the lower pad body 20a, compressed cotton is adopted. 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. Hence, a consideration is given such that the upper pad body 10a disposed closer to the user provides a soft and fluffy feel, and a consideration is given such that in the lower pad body 20a, for example, the cotton CT2 is unlikely to wear out, and the feeling of hitting the bottom and the like are minimized. As the cotton CT2 of the lower pad body 20a, sheet-shaped cotton is used. The cotton CT2 is formed by compression, and the cotton CT2 is designed to feel as if it has been already worn out so that the cotton CT2 does not feel as if it is worn out with use.

[0043] Preferably, the surfaces of the upper pad 10 and the lower pad 20 which make contact with each other in the up / down direction (that is, the lower surface of the upper pad body 10a and the upper surface of the lower pad body 20a) are unlikely to slide on each other. In a part or the whole of the surface of the upper pad 10 which makes contact with the lower pad 20 (lower source of the upper pad body 10a), a friction-inducing portion may be formed. Likewise, in a part or the whole of the surface of the lower pad 20 which makes contact with the upper pad 10 (upper surface of the lower pad body 20a), a friction-inducing portion may be formed. Examples of the friction-inducing portion include a hook and loop fastener and the like. As the friction-inducing portion, a nap may be raised from the lower surface of the upper pad body 10a. A nap may also be raised from the upper surface of the lower pad body 20a. It is desirable that a portion of the lower surface of the upper pad body 10a from which the nap is raised and a portion of the upper surface of the lower pad body 20a from which the nap is raised are tangled together, and thus the surfaces which make contact with each other are unlikely to slide on each other in a direction orthogonal to the up / down direction. In this way, it is possible to minimize the loss of sleeping comfort caused by the sliding of the upper pad 10 and the lower pad 20.

[0044] Although in the example of the first embodiment, the pair of fasteners 30 which are the upper fastener 31 and the lower fastener 32 are adopted as a joining portion which can switch the upper pad 10 and the lower pad 20 between the joined state and the separated state, another form may be adopted instead of the pair of fasteners 30 (or together with the fasteners). Examples of the form which may be adopted include a form where a button is used (where a button is provided in one of both pads 10 and 20, and a hole into which the button can be fitted is provided in the other), a form where hook and loop fasteners are used (where hook and loop fasteners which can be adhered to each other are provided in both pads 10 and 20) and a form where strings are used (where strings are respectively provided in both pads 10 and 20, and both pads 10 and 20 are joined by tying the strings together). The upper pad 10 and the lower pad 20 can be interchanged between the upper and lower sides according to the preference of the user. For example, the upper pad 10 and the lower pad 20 may be combined together by placing the lower pad 20 on the upper pad 10 and coupling the upper fastener 31 to the lower fastener 32.

[0045] In the form where the hook and loop fasteners are used as the joining portion, as the hook and loop fastener, a hook and loop fastener (which includes a first raw cloth having a loop fiber layer and a second raw cloth having a hook fiber layer) disclosed in Japanese Unexamined Patent Application Publication No. 2020-120918 may be adopted. In other words, the first raw cloth may be provided in one of the upper pad 10 and the lower pad, and the second raw cloth may be provided in the other.

[0046] In the hook and loop fastener, the loop fiber layer is configured with multiple loop fibers formed of first temporary twisted crimped pile yarn, and the hook fiber layer is configured with multiple hook fibers formed of second temporary twisted crimped pile yarn. The first temporary twisted crimped pile yarn is a non-twisted temporary twisted crimped pile yarn obtained by temporarily twisting a bundle of resin fibers having a single yarn fineness of 0.15 dtex or more and 0.7 dtex or less under the condition of a temporary twisting coefficient of 20,000 to 32,000, and the second temporary twisted crimped pile yarn is a non-twisted temporary twisted crimped pile yarn obtained by temporarily twisting a bundle of resin fibers having a single yarn fineness of 1.5 dtex or more and 3.8 dtex or less under the condition of a temporary twisting coefficient of 20,000 to 32,000. In the hook and loop fastener, the loop fibers and the hook fibers engage with each other, and thus the first raw cloth and the second raw cloth are joined.2. Second Embodiment

[0047] A second embodiment will then be described. The second embodiment is basically the same as the first embodiment except that a cover unit is provided and a configuration related to the control unit is provided. Differences from the first embodiment will be mainly described below, and the description of the same configurations as in the first embodiment may be omitted.

[0048] In the second embodiment, a lower pad 20 includes the cover unit which covers the entire side surface of an upper pad 10 (upper pad body 10a). FIG. 6 is a schematic perspective view of elements of a bedding pad 1 in which the cover unit as described above is provided. FIG. 7 is a schematic cross-sectional view of the lower pad 20 shown in FIG. 6 taken along a plane orthogonal to the forward / backward direction in the vicinity of a center in the forward / backward direction.

[0049] In the lower pad 20 shown in FIG. 6, the cover unit 22 which uses a fabric as a raw material is attached to a lower pad body 20a. The cover unit 22 is attached to the entire periphery (part indicted by α in FIG. 7) of the lower surface of the lower pad body 20a, for example, by sewing, and extends upward from the entire periphery by a predetermined amount (to a part indicated by β in FIG. 7). The cover unit 22 further extends from the part indicated by β in FIG. 7 inward in the left / right direction or in the forward / backward direction by a predetermined amount (to a part indicated by γ in FIG. 7).

[0050] The cover unit 22 formed as described above covers the entire side surface of the upper pad 10 in a position indicated by dotted lines in FIG. 7 (upper pad 10 joined to the lower pad 20 with the pair of fasteners 30). In this way, the pair of fasteners 30 can be hidden by the cover unit 22, the bedding pad 1 in the joined state can appear more integrated and design enhancement can be expected. The cover unit in the present embodiment is formed to cover not only the entire side surface of the upper pad 10 but also an area in the vicinity of the entire edge of the upper surface of the upper pad 10.3. Third Embodiment

[0051] A third embodiment will then be described. The third embodiment is basically the same as the first embodiment except that a storage unit is provided and a configuration related to the storage unit is provided. Differences from the first embodiment will be mainly described below, and the description of the same configurations as in the first embodiment may be omitted.

[0052] In a bedding pad according to the third embodiment, as a joining portion which can switch an upper pad 10 and a lower pad 20 between the joined state and the separated state, a bag-shaped storage unit is adopted which is provided in one of the upper pad 10 and the lower pad 20 and is capable of storing the other. FIG. 8 is a schematic perspective view of elements of the bedding pad 1 in which the storage unit as described above is provided.

[0053] The lower pad 20 shown in FIG. 8 includes, on the upper side of a lower pad body 20a, the storage unit 23 which uses a fabric as a raw material. More specifically, the storage unit 23 includes; a side surface portion 23a which extends upward from parts of the outer edge of the upper surface of the lower pad body 20a (that is, a side on a front side, a side on a left side and a side on a back side) other than a side on a right side; and an upper surface portion 23b which is disposed opposite the upper surface of the lower pad body 20a and is connected to the entire edge of the upper side of the side surface portion 23a. The storage unit 23 as described above is formed in the shape of a bag together with the upper surface of the lower pad body 20a. In the storage unit 23 in the shape of a bag, an opening Z is provided on the right side.

[0054] Hence, as indicated by a dotted line with arrows in FIG. 8, the upper pad 10 can be freely inserted into and removed from the storage unit 23 via the opening Z. The upper pad 10 is stored into the storage unit 23, and thus the bedding pad 1 is brought into the joined state where the upper pad 10 and the lower pad 20 are joined. On the other hand, the upper pad 10 is removed from the interior of the storage unit 23, and thus the bedding pad 1 is brought into the separated state where the upper pad 10 is separated from the lower pad 20. In the present embodiment, the storage unit 23 serves as the joining portion, and thus the installation of the pair of fasteners 30 is omitted.

[0055] As described above, the storage unit 23 functions as the joining portion which can switch the upper pad 10 and the lower pad 20 between the joined state and the separated state. The shape and the size of the storage unit 23 are appropriately set such that the upper pad 10 is fitted into the storage unit 23. Although in the example shown in FIG. 8, the opening Z in the storage unit 23 is provided on the right side, the opening Z may be provided on the left side, the front side or the back side. The opening Z may be openable. For example, in the opening Z, a removable member such as a fastener, a button or a hook and loop fastener may be provided. Multiple pads may be stacked and stored in the storage unit 23. Multiple pads are selectively stacked and stored as described above, and thus it is possible to obtain softness, the feeling of hitting the bottom and the like corresponding to the preference of the user.

[0056] Although in the example shown in FIG. 8, the storage unit which stores the upper pad 10 is provided in the lower pad 20, instead of the storage unit described above, a storage unit which stores the lower pad 20 may be provided in the upper pad 10. In this case, the storage unit is preferably provided on the lower side of the upper pad body 10a. In this way, as compared with the case where the storage unit is provided in the lower pad 20 (case where the upper pad 10 formed to be relatively soft is inserted into and removed from the storage unit), the lower pad 20 which is formed to be relatively hard is inserted into and removed from the storage unit, with the result that an operation of inserting and removing the lower pad 20 into and from the storage unit can easily be performed.4. Fourth Embodiment

[0057] A fourth embodiment will then be described. Differences from the first embodiment will be mainly described below, and the description of the same configurations as in the first embodiment may be omitted.

[0058] FIG. 9 is a front view of a bedding pad 1 (cushioning member) in a basic form according to the fourth embodiment. The bedding pad 1 in the basic form is in the joined state where an upper pad 10 and a lower pad 20 are joined with fasteners 30 to be vertically overlaid on each other. FIG. 10 is a left side view of the bedding pad 1 in the basic form. FIG. 11 is a right side view of the bedding pad 1 in the basic form. FIG. 12 is a plan view of the bedding pad 1 in the basic form. A bottom view of the bedding pad 1 in the basic form is shown symmetrically with the plan view shown in FIG. 12. A back view of the bedding pad 1 in the basic form is shown symmetrically with the front view shown in FIG. 9.

[0059] In the bedding pad 1 in the basic form, the upper pad 10 and the lower pad 20 disposed on the lower side thereof are coupled by completely closing the fasteners 30. The fasteners 30 extend over the entire side surface of the bedding pad 1. By moving a pull tab 30a to open the fasteners 30, the upper pad 10 and the lower pad 20 can be separated in the opened part.

[0060] Although the fasteners 30 are completely opened to completely separate the upper pad 10 and the lower pad 20, as indicated by a dotted line with an arrow in a reference diagram (diagram having the same view point as the plan view) shown in FIG. 13, the pull tab 30a is moved, and thus the fasteners 30 are brought into an opened state except a part (part indicated by α in FIG. 13) of the side surface on the right side. When the upper pad 10 is pulled upward in this state, the upper pad 10 is moved to rotate with the extended part of the fasteners 30 in the side surface on the right side serving as an axis. In this way, the bedding pad 1 is changed based on the functions of the bedding pad 1 from the basic form (form shown in FIG. 9 and the like) to a changed form (form shown in FIGS. 14 to 18 which will be described later).

[0061] FIG. 14 is a front view of the bedding pad 1 which has been changed. FIG. 15 is a left side view of the bedding pad 1 which has been changed. FIG. 16 is a right side view of the bedding pad 1 which has been changed. FIG. 17 is a plan view of the bedding pad 1 which has been changed. FIG. 18 is a bottom view of the bedding pad 1 which has been changed. A back view of the bedding pad 1 which has been changed is shown symmetrically with the front view shown in FIG. 14. The bedding pad 1 is brought into the changed form, and thus while the upper pad 10 and the lower pad 20 are being partially coupled, the interior of the bedding pad 1 is exposed, with the result that it is possible to perform a visual check and the like.5. Others

[0062] The bedding pad 1 according to each of the embodiments described above is brought into the joined state where the upper pad 10 and the lower pad 20 are joined with the joining portion to be vertically overlaid on each other, and is laid on the bedding on which the user lies to be used, and the joining portion is capable of switching the upper pad 10 and the lower pad 20 between the joined state and the separated state.

[0063] In each of the first, second and fourth embodiments, the joining portion includes the pair of fasteners 30 which include the upper fastener 31 provided on the upper pad 10 and the lower fastener 32 provided on the lower pad 20, the upper fastener 31 engages with the lower fastener 32 and thus the upper pad 10 and the lower pad 20 are brought into the joined state. On the other hand, in the third embodiment, the joining portion is the storage unit. Although in the third embodiment, the storage unit is provided in the lower pad 20, the storage unit may be provided in the upper pad instead of the lower pad. In other words, the joining portion is the bag-shaped storage unit which is provided in one of the upper pad 10 and the lower pad 20, and is capable of storing the other. The other is stored in the storage unit, and thus the upper pad 10 and the lower pad 20 are brought into the joined state.

[0064] It should be considered that the embodiments described above are illustrative in all respects, and not restrictive. It should be considered that the technical scope of the present invention is indicated not by the description of the above embodiments but by the scope of claims, and meanings equivalent to the scope of claims and all modifications within the scope are included therein.
