[0009] Hereinafter, a bedding pad 100 according to an embodiment of the present invention will be described with reference to the drawings. Figures 1 and 2 show examples of the configuration of the bedding pad 100. Specifically, Figure 1 is a perspective view of the bedding pad 100, the upper part of Figure 2 is a top view of the bedding pad 100, and the lower part of Figure 2 is a bottom view of the bedding pad 100. Figure 3 is an exploded view of the bedding pad 100. Specifically, Figure 3 is a top view of each component constituting the bedding pad 100.

[0010] In Figure 1, X1 represents one direction of the X-axis in the three-dimensional Cartesian coordinate system, and X2 represents the other direction of the X-axis. Similarly, Y1 represents one direction of the Y-axis in the three-dimensional Cartesian coordinate system, and Y2 represents the other direction of the Y-axis. Likewise, Z1 represents one direction of the Z-axis in the three-dimensional Cartesian coordinate system, and Z2 represents the other direction of the Z-axis. In Figure 1, the X1 side of the bedding pad 100 corresponds to the front side of the bedding pad 100, and the X2 side of the bedding pad 100 corresponds to the back side of the bedding pad 100. Also, the Y1 side of the bedding pad 100 corresponds to the left side of the bedding pad 100, and the Y2 side of the bedding pad 100 corresponds to the right side of the bedding pad 100. Furthermore, the Z1 side of the bedding pad 100 corresponds to the upper side of the bedding pad 100, and the Z2 side of the bedding pad 100 corresponds to the lower side of the bedding pad 100. The same applies to other components in the other figures.

[0011] The bedding pad 100, as shown in Figures 1 to 3, includes a pad PD, a fabric member CM, and an elastic member EC, and is also called a "gusseted bedding pad." In a gusseted bedding pad, the fabric member CM corresponds to the "gusset." In the illustrated example, the bedding pad 100 has a pad PD and an annular fabric member CM sewn to the pad PD. In Figure 1, for clarity, the pad PD is given a cross pattern and the elastic member EC is given a dot pattern.

[0012] Specifically, the pad PD is a component that comes into direct contact with the skin and is placed on the top surface of the mattress MT (see Figure 7) or bedding such as a pillow. In the illustrated example, the pad PD is a mattress pad placed on the top surface of the mattress MT, and is typically composed of an upper fabric, a lower fabric, and a filling placed between the upper and lower fabrics. The filling may be, for example, cotton, wool, polyester, cooling gel, polyurethane foam, or a combination thereof.

[0013] The fabric component CM is made of stretch fabric, and its outer edge is sewn to the outer edge of the pad PD. The stretch fabric is composed of, for example, polyurethane elastic fibers.

[0014] The elastic member EC is a stretchable member sewn to the inner edge of the cloth member CM. Specifically, the elastic member EC is formed of flat rubber and has a higher elongation rate than the cloth member CM formed of stretch fabric. In the illustrated example, the elastic member EC is flat rubber formed of 42-denier double yarn, and the elongation rate of the elastic member EC is 2.8 times (280%) or more.

[0015] In FIG. 2, the seam SE between the members is represented by a dotted line. Specifically, the seam SE includes a first seam SE1 that is a seam between the cloth member CM and the elastic member EC, a second seam SE2 that is a seam between the pad PD and the cloth member CM, and a third seam SE3 that is a seam between a part of the cloth member CM and another part of the cloth member CM.

[0016] In the illustrated example, the cloth member CM is configured to have four corner portions CN in a bottom view. Specifically, the corner portions CN are portions inside the second seam SE2 and include a left front corner portion CN1, a left rear corner portion CN2, a right rear corner portion CN3, and a right front corner portion CN4. In FIG. 2, for easy understanding of the explanation, a thick dot pattern is attached to each of the four corner portions CN. As shown in FIG. 2, the cloth member CM is configured such that seams and folds are not formed at the corner portions CN. That is, the corner portions CN are formed of a single flat stretch fabric. With this configuration, the cloth member CM can exert a greater tightening force to tighten the side surface of the corner of the bedding accommodated in the bedding pad 100 from the outside to the inside, compared to the case where seams or folds are formed at the corner portions CN. Further, the cloth member CM can exert a greater tightening force to tighten the lower surface of the corner of the bedding accommodated in the bedding pad 100 from the bottom side to the top side, compared to the case where seams or folds are formed at the corner portions CN. Therefore, the bedding pad 100 can more reliably suppress the sliding of the pad PD on the upper surface of the bedding, compared to the case where seams or folds are formed at the corner portions CN. Note that this effect is achieved if at least one of the four corner portions CN in the cloth member CM is formed without seams and folds, but it is preferable that at least two of the four corner portions CN that are on the diagonal line are formed without seams and folds.

[0017] Furthermore, in the illustrated example, the pad PD is a substantially rectangular member having a width W1 and a length L1, as shown in Figure 3. The fabric member CM has a substantially rectangular annular shape when viewed from below after being sewn onto the pad PD, as shown in the lower part of Figure 2, and is a strip-shaped member having a width W2 and a length L1 before being sewn onto the pad PD, as shown in Figure 3. The elastic member EC has a substantially rectangular annular shape when viewed from below after being sewn onto the fabric member CM, as shown in the lower part of Figure 2, and is a strip-shaped member having a width W3 and a length L3 before being sewn onto the fabric member CM, as shown in Figure 3. Note that the elastic member EC may be configured to have a substantially elliptical annular shape when viewed from below after being sewn onto the fabric member CM, as shown in the lower part of Figure 2.

[0018] Specifically, the length L2 of the fabric member CM is smaller than the outer circumference of the pad PD (width W1 + length L1 + width W1 + length L1). In the illustrated example, as shown in Figure 3, the length L2 of the fabric member CM roughly corresponds to the length obtained by subtracting four times the width W2 of the fabric member CM (4 × width W2) from the outer circumference of the pad PD (width W1 + length L1 + width W1 + length L1). Also, as shown in Figure 3, the length L2 of the fabric member CM is larger than twice the length L3 of the elastic member EC (2 × length L3). In the illustrated example, when the bedding pad 100 is for a single-size mattress, the lengths L2 of the fabric member CM and L3 of the elastic member EC are 600 cm and 250 cm, respectively. When the bedding pad 100 is for a semi-double-size mattress, the lengths are 640 cm and 270 cm, respectively. When the bedding pad 100 is for a double-size mattress, the lengths are 680 cm and 290 cm, respectively. In other words, the length L3 of the elastic member EC is approximately 41.7% of the length L2 of the fabric member CM when the bedding pad 100 is for a single-size mattress, approximately 42.2% of the length L2 of the fabric member CM when the bedding pad 100 is for a semi-double-size mattress, and approximately 42.6% of the length L2 of the fabric member CM when the bedding pad 100 is for a double-size mattress.

[0019] Next, the manufacturing method of the bedding pad 100 will be described with reference to Figures 4 and 5. Figure 4 is a top view of the fabric member CM to which the elastic member EC is sewn. Figure 5 is a diagram showing the procedure for sewing the fabric member CM to which the elastic member EC is sewn onto the pad PD. Specifically, each of the four figures in Figure 5 is a top view of the fabric member CM to which the elastic member EC is sewn onto the pad PD.

[0020] In the illustrated example, the left edge of the elastic member EC is sewn to the right edge of the fabric member CM by a sewing machine, as shown in Figure 4. At the stage of sewing the elastic member EC to the fabric member CM, neither the fabric member CM nor the elastic member EC has been cut. That is, the fabric member CM and the elastic member EC are cut to a predetermined length after being sewn together. The sewing machine is set so that the feed rate of the fabric member CM is greater than the feed rate of the elastic member EC, so that the length L3 of the elastic member EC after cutting is less than half the length L2 of the fabric member CM. That is, the feed rate of the elastic member EC is set to be less than half the feed rate of the fabric member CM. The feed rate refers to the length of fabric fed per unit time in the feeding direction. As a result, when the elastic member EC is in its natural state, the fabric member CM is wrinkled, as shown in Figure 4.

[0021] In reality, the fabric member CM to which the elastic member EC is sewn is wrinkled, as described above. However, in Figure 5, for the sake of clarity, the fabric member CM to which the elastic member EC is sewn is shown in a wrinkle-free, stretched state. Furthermore, the elastic member EC is shown stretched to more than twice its length, so that it is the same length as the fabric member CM.

[0022] Specifically, the first fabric portion CM1 of the fabric member CM to which the elastic member EC is sewn is first sewn to the left (Y1 side) outer edge of the pad PD, as shown in the upper left diagram of Figure 5. The first fabric portion CM1 is a part of the fabric member CM that is sewn to the left outer edge of the pad PD. The second left seam SE21 is a part of the second seam SE2 and represents the seam between the first fabric portion CM1 and the left outer edge of the pad PD.

[0023] Subsequently, the second fabric portion CM2 of the fabric member CM, to which the elastic member EC is sewn, is sewn to the outer edge of the rear side (X2 side) of the pad PD, as shown in the upper right diagram of Figure 5. The second fabric portion CM2 is a part of the fabric member CM that is sewn to the outer edge of the rear side of the pad PD. The second rear seam SE22 is a part of the second seam SE2 and represents the seam between the second fabric portion CM2 and the outer edge of the rear side of the pad PD.

[0024] Subsequently, the third fabric portion CM3 of the fabric member CM, to which the elastic member EC is sewn, is sewn to the right (Y2 side) outer edge of the pad PD, as shown in the lower left diagram of Figure 5. The third fabric portion CM3 is a part of the fabric member CM that is sewn to the right outer edge of the pad PD. The second right seam SE23 is a part of the second seam SE2 and represents the seam between the third fabric portion CM3 and the right outer edge of the pad PD.

[0025] Subsequently, the fourth fabric portion CM4 of the fabric member CM, to which the elastic member EC is sewn, is sewn to the outer edge of the front side (X1 side) of the pad PD, as shown in the lower right diagram of Figure 5. The fourth fabric portion CM4 is a part of the fabric member CM that is sewn to the outer edge of the front side of the pad PD. The second front seam SE24 is a part of the second seam SE2 and represents the seam between the fourth fabric portion CM4 and the outer edge of the front side of the pad PD.

[0026] Subsequently, the tip (left end) of the fourth fabric portion CM4 is sewn to the right outer edge of the first fabric portion CM1, as shown in the lower right diagram of Figure 5. The third seam SE3 represents the seam between the first fabric portion CM1 and the fourth fabric portion CM4.

[0027] Next, referring to Figures 6 and 7, the force exerted by the fabric member CM, formed from stretch fabric, on the bedding contained within the bedding pad 100 will be explained. Figure 6 is a diagram showing an example of the configuration of the bedding pad 100. Specifically, the upper part of Figure 6 is a perspective view of the bedding pad 100, and the lower part of Figure 6 is a bottom view of the bedding pad 100. Figure 7 is a diagram showing the relationship between the mattress MT contained within the bedding pad 100 and the bedding pad 100. Specifically, the upper part of Figure 7 is a perspective view of the bedding pad 100 before the mattress MT is placed inside, the middle part of Figure 7 is a perspective view of the mattress MT placed inside the bedding pad 100, and the lower part of Figure 7 is a perspective view of the bedding pad 100 with the mattress MT inside. In the illustrated example, the mattress MT is a single-size mattress.

[0028] As shown in Figure 6, when the bedding pad 100 is lifted with the top surface of the pad PD facing upwards, the fabric member CM is configured to hang down from the flat outer edge of the pad PD, forming an inverted frustum shape (outline). In other words, the fabric member CM is configured to be in the shape of an inverted frustum cylinder. In the illustrated example, the fabric member CM hangs down from the outer edge of the roughly rectangular pad PD in a top view, forming an inverted frustum shape.

[0029] Specifically, the fabric member CM is configured such that its outer circumference length CF decreases as it moves away from the pad PD. More specifically, the fabric member CM is configured such that at the outer edge of the pad PD, the outer circumference length CF is length CF1, at a distance D1 vertically (Z2 direction) from the outer edge of the pad PD, the outer circumference length CF is length CF2 (<length CF1), and at a distance D2 vertically (>distance D1) from the outer edge of the pad PD, the outer circumference length CF is length CF3 (<length CF2).

[0030] With this configuration, when bedding is placed inside the bedding pad PD such that the bedding is in contact with both the lower surface of the pad PD and the inner surface of the fabric member CM, the fabric member CM, which is made of stretch fabric, can tighten the sides of the bedding from the outside to the inside. As a result, the bedding pad 100 can prevent the pad PD from sliding on the upper surface of the bedding.

[0031] Typically, when the bedding pad 100 accommodates columnar bedding having the same cross-sectional shape as the outer shape of the pad PD, the fabric member CM can tighten the sides of the bedding from the outside inward.

[0032] In the illustrated example, as shown in Figure 7, when the bedding pad 100 accommodates a mattress MT, which is a rectangular prism-shaped bedding with the same cross-sectional shape as the rectangular shape of the pad PD, the fabric member CM can tighten each of the four sides of the mattress MT from the outside inward. The tightening force by the fabric member CM increases with increasing distance from the outer edge of the pad PD, as shown in the lower part of Figure 7. The lower part of Figure 7 shows that the tightening force at a greater distance from the outer edge of the pad PD (indicated by the thick arrow AR1) is greater than the tightening force at a smaller distance from the outer edge of the pad PD (indicated by the thin arrow AR2).

[0033] Next, with reference to Figure 8, an example of the relationship between the size of the bedding contained in the bedding pad 100 and the size of the fabric member CM will be explained. Figure 8 is a downward perspective view of the bedding pad 100 containing a mattress MT, which is an example of bedding.

[0034] In the example shown in Figure 8, the mattress MT is a single-size mattress with a height H1, and the bedding pad 100 is manufactured for a single-size mattress. When the mattress MT is placed inside, the fabric member CM has a side portion CMa that covers the sides of the mattress MT, and a bottom portion CMb that covers a part of the bottom surface of the mattress MT. The bottom portion CMb also includes a first bottom portion CMb1 that covers the left edge of the bottom surface of the mattress MT, a second bottom portion CMb2 that covers the rear edge of the bottom surface of the mattress MT, a third bottom portion CMb3 that covers the right edge of the bottom surface of the mattress MT, and a fourth bottom portion CMb4 that covers the front edge of the bottom surface of the mattress MT.

[0035] Furthermore, when the mattress MT is placed inside, the fabric member CM is configured such that the first lower portion CMb1 has a width MG1 in the Y-axis direction, the second lower portion CMb2 has a width MG2 in the X-axis direction, the third lower portion CMb3 has a width MG3 in the Y-axis direction, and the fourth lower portion CMb4 has a width MG4 in the X-axis direction.

[0036] In the illustrated example, the fabric member CM is configured such that widths MG1 and MG3 are the same size, and widths MG2 and MG4 are the same size. Furthermore, the fabric member CM is configured such that each of widths MG1 to MG4 has a height of H1 or greater.

[0037] Furthermore, in the illustrated example, the fabric member CM is configured to cover a predetermined percentage of the surface area of ​​the underside of the mattress MT. This predetermined percentage is, for example, 50% or less.

[0038] This configuration allows the fabric member CM, made of stretch fabric, to tighten the underside of the mattress MT from bottom to top with a predetermined tightening force. As a result, the bedding pad 100 can prevent the pad PD from sliding on the top surface of the bedding.

[0039] However, the fabric member CM may be configured such that each of the widths MG1 to MG4 are of different sizes, or may be configured so that each of the widths MG1 to MG4 are of the same size, as long as the predetermined clamping force can be secured. Alternatively, the fabric member CM may be configured such that widths MG1 and MG3 are at or above height H1, while widths MG2 and MG4 are at or below height H1, or widths MG1 and MG3 are at or above height H1, while widths MG2 and MG4 are at or above height H1.

[0040] In the example shown in Figure 8, the fabric member CM is configured such that the inner edge of the lower portion CMb is rectangular when viewed from below. However, the inner edge of the lower portion CMb may be configured to be circular or elliptical when viewed from below. In this case, width MG1 is replaced by the width of the narrowest part of the first lower portion CMb1. The same applies to widths MG2 to MG4.

[0041] Next, with reference to Figure 9, we will describe another configuration example of the bedding pad 100, bedding pad 100A. Figure 9 is a downward perspective view of the bedding pad 100A containing a mattress MT, which is an example of bedding.

[0042] The bedding pad 100A differs from the bedding pad 100 in that it has an elastic member EC that has a roughly octagonal ring shape when viewed from below, but is otherwise the same as the bedding pad 100. Therefore, the explanation of the common parts will be omitted below, and the differences will be explained in detail.

[0043] In the example shown in Figure 9, the mattress MT is a single-size mattress with a height H1, and the bedding pad 100A is manufactured for a single-size mattress. When the mattress MT is placed inside, the fabric member CM has a side portion CMa that covers the sides of the mattress MT, and a corner portion CMc that covers the corners of the bottom surface of the mattress MT. The corner portion CMc also includes a first corner portion CMc1 that covers the left front corner of the bottom surface of the mattress MT, a second corner portion CMc2 that covers the left rear corner of the bottom surface of the mattress MT, a third corner portion CMc3 that covers the right rear corner of the bottom surface of the mattress MT, and a fourth corner portion CMc4 that covers the right front corner of the bottom surface of the mattress MT.

[0044] Furthermore, when the mattress MT is placed inside, the fabric member CM is configured such that the left portion of the elastic member EC is located on the left edge of the lower surface of the mattress MT, the rear portion of the elastic member EC is located on the rear edge of the lower surface of the mattress MT, the right portion of the elastic member EC is located on the right edge of the lower surface of the mattress MT, and the front portion of the elastic member EC is located on the front edge of the lower surface of the mattress MT. In other words, the fabric member CM may be omitted if it is possible to secure four corner portions CMc of appropriate size, in which case the portion extending between two corner portions CMc (the portion of the lower surface portion CMb other than the four corner portions shown in Figure 8) may be omitted.

[0045] This configuration allows the bedding pad 100A to reduce the amount of fabric material CM used compared to the bedding pad 100, while still ensuring adequate tightening force to secure the mattress MT housed inside.

[0046] Next, referring to Figure 10, we will describe another configuration example of the bedding pad 100, which is bedding pad 100B. Figure 10 is a diagram showing an example configuration of bedding pad 100B and corresponds to Figure 2. Specifically, the upper part of Figure 10 is a top view of bedding pad 100B, and the lower part of Figure 10 is a bottom view of bedding pad 100B.

[0047] The bedding pad 100B differs from the bedding pad 100, which includes a fabric member CM made of a strip-shaped stretch fabric, in that the elastic member EC is omitted and the fabric member CM is formed of a roughly rectangular annular stretch fabric. However, it is the same as the bedding pad 100 in all other respects. Therefore, the explanation of the common parts will be omitted below, and the differences will be explained in detail.

[0048] In the bedding pad 100B, the fabric member CM is formed by cutting out the central portion from a stretch fabric having approximately the same size (width and length) as the pad PD. That is, the fabric member CM has an opening OP in the central portion, as shown in the lower part of Figure 10.

[0049] The outer edge of the fabric component CM is sewn to the outer edge of the pad PD. Figure 10 shows the state in which the outer edge of the fabric component CM and the outer edge of the pad PD are sewn together, indicated by the dotted seam SE.

[0050] With this configuration, when bedding is placed inside the bedding pad 100B so that the bedding is in contact with both the lower surface of the pad PD and the inner surface of the fabric member CM, the fabric member CM, which is made of stretch fabric, can tighten the sides of the bedding from the outside to the inside. Therefore, the bedding pad 100B can prevent the pad PD from sliding on the upper surface of the bedding.

[0051] In the example shown in Figure 10, the elastic member EC is omitted, but the bedding pad 100B may have the elastic member EC. That is, the elastic member EC may be sewn to the inner edge of the fabric member CM.

[0052] Next, referring to Figure 11, we will describe two further configuration examples of the bedding pad 100, namely bedding pad 100C and bedding pad 100D. Figure 11 is a diagram showing yet another configuration example of the bedding pad 100, corresponding to Figures 2 and 10, respectively. Specifically, the upper left of Figure 11 is a top view of bedding pad 100C, and the lower left of Figure 11 is a bottom view of bedding pad 100C. Also, the upper right of Figure 11 is a top view of bedding pad 100D, and the lower right of Figure 11 is a bottom view of bedding pad 100D.

[0053] Bedding pad 100C differs from bedding pad 100B, which has a roughly rectangular shape when viewed from above, in that it has a roughly elliptical shape when viewed from above, but is otherwise identical to bedding pad 100B. Similarly, bedding pad 100D differs from bedding pad 100B, which has a roughly rectangular shape when viewed from above, in that it has a roughly octagonal shape when viewed from above, but is otherwise identical to bedding pad 100B. Therefore, the explanation of the common parts will be omitted below, and the differences will be explained in detail.

[0054] In bedding pad 100C, the fabric member CM is configured to have the same outer shape (approximately elliptical) as the outer shape (approximately elliptical) of pad PD when viewed from above, and to hang down from the outer edge of the approximately elliptical pad PD to form an inverted elliptical frustoconical shape. In other words, the fabric member CM is configured to be in the shape of an inverted elliptical frustoconical cylinder. In bedding pad 100D, the fabric member CM is configured to have the same outer shape (approximately octagonal) as the outer shape (approximately octagonal) of pad PD when viewed from above, and to hang down from the outer edge of the approximately octagonal pad PD to form an inverted octagonal frustoconical shape. In other words, the fabric member CM is configured to be in the shape of an inverted octagonal frustoconical cylinder.

[0055] With this configuration, both the bedding pad 100C and the bedding pad 100D, like the bedding pad 100, can tighten the sides of the bedding from the outside to the inside with the stretch fabric material CM when the bedding is placed so that the bedding is in contact with the lower surface of the pad PD and the inner surface of the fabric material CM, respectively. Therefore, the bedding pad 100B can prevent the pad PD from sliding on the upper surface of the bedding.

[0056] Next, with reference to Figure 12, we will describe another configuration example of the bedding pad 100, which is the bedding pad 100E. Figure 12 is a diagram showing an example configuration of the bedding pad 100E. Specifically, the upper part of Figure 12 is a bottom view of the bedding pad 100E before the third seam SE3, which is a seam between one part of the fabric member CM and another part of the fabric member CM, is formed, and the lower part of Figure 12 is a bottom view of the bedding pad 100E after the third seam SE3 has been formed.

[0057] The bedding pad 100E differs from the bedding pad 100 in that its fabric member CM includes four fabric members CM (first fabric member CM11 to fourth fabric member CM14) and its elastic member EC includes four elastic members EC (first elastic member EC11 to fourth elastic member EC14), but is otherwise the same as the bedding pad 100.

[0058] Specifically, each of the first fabric member CM11 to the fourth fabric member CM14 is a stretch fabric cut to form a trapezoid with the side sewn to the pad PD as the bottom base and the side sewn to the elastic member EC as the top base. In the illustrated example, each of the first fabric member CM11 to the fourth fabric member CM14 is a stretch fabric cut to form an isosceles trapezoid with two interior angles at both ends of the bottom base being equal in size and two base angles at both ends of the top base being equal in size.

[0059] In the illustrated example, as shown in the upper diagram of Figure 12, the first fabric member CM11 has the first elastic member EC11 sewn to its upper bottom portion, and then the lower bottom portion is sewn to the left edge of the pad PD. The first left seam SE11 is a part of the first seam SE1 and represents the seam between the first fabric member CM11 and the first elastic member EC11. The second fabric member CM12 has the second elastic member EC12 sewn to its upper bottom portion, and then the lower bottom portion is sewn to the rear edge of the pad PD. The first rear seam SE12 is a part of the first seam SE1 and represents the seam between the second fabric member CM12 and the second elastic member EC12. The third fabric member CM13 has the third elastic member EC13 sewn to its upper bottom portion, and then the lower bottom portion is sewn to the right edge of the pad PD. The first right seam SE13 is part of the first seam SE1 and represents the seam between the third fabric member CM13 and the third elastic member EC13. Similarly, the fourth fabric member CM14 has its lower bottom sewn to the front edge of the pad PD after the fourth elastic member EC14 is sewn to its upper bottom. The first front seam SE14 is part of the first seam SE1 and represents the seam between the fourth fabric member CM14 and the fourth elastic member EC14.

[0060] Subsequently, the four fabric members CM (first fabric member CM11 to fourth fabric member CM14) are folded inward so that the trapezoidal legs of two adjacent fabric members CM overlap, as shown in the lower diagram of Figure 12, and then sewn together. The third seam SE3 indicates that the trapezoidal legs of two adjacent fabric members CM have been sewn together. Specifically, the third left front seam SE31 is a part of the third seam SE3 and represents the seam between the first fabric member CM11 and the fourth elastic member EC14. The third left rear seam SE32 is also a part of the third seam SE3 and represents the seam between the first fabric member CM11 and the second elastic member EC12. The third right rear seam SE33 is also a part of the third seam SE3 and represents the seam between the second fabric member CM12 and the third elastic member EC13. Furthermore, the third right front seam SE34 is a part of the third seam SE3 and represents the seam between the third fabric member CM13 and the fourth elastic member EC14.

[0061] In the bedding pad 100E, the fabric member CM is configured to have the same outer shape (approximately rectangular) as the outer shape (approximately rectangular) of the pad PD when viewed from above, and to hang down from the outer edge of the approximately rectangular pad PD to form an inverted truncated pyramidal shape. That is, the fabric member CM is configured to be in the shape of an inverted truncated pyramidal cylinder. A rectangular annular elastic member EC may be sewn to the inner edge of the rectangular annular shape formed by the upper bottom of each of the four fabric members CM (first fabric member CM11 to fourth fabric member CM14). In this case, the elastic member EC may be sewn to the fabric member CM after the fabric member CM has been sewn to the pad PD. The elastic member EC may also be omitted.

[0062] With this configuration, the bedding pad 100E, like the bedding pad 100, can tighten the sides of the bedding from the outside to the inside with the stretch fabric material CM when the bedding is placed inside the bedding pad 100E so that the bedding is in contact with the lower surface of the pad PD and the inner surface of the fabric material CM. Therefore, the bedding pad 100E can prevent the pad PD from sliding on the upper surface of the bedding.

[0063] As described above, the bedding pad 100 according to the embodiment of the present invention is also called a gusseted bedding pad, and as shown in Figure 1, it has a pad PD which is placed on the upper surface of bedding such as a mattress MT, and an annular fabric member CM which is sewn to the pad PD. The fabric member CM is made of stretch fabric and its outer edge is sewn to the outer edge of the pad PD. The annular fabric member CM is, for example, a fabric member in which the outer circumference is greater than the inner circumference is greater than the inner circumference.

[0064] With this configuration, when the bedding pad 100 is attached to the bedding (mattress MT, etc.), the fabric member CM made of stretch fabric can tighten the sides of the bedding. Therefore, the bedding pad 100 can prevent the pad PD, which is placed on the surface of the bedding, from sliding on the surface of the bedding.

[0065] Furthermore, as shown in Figure 1, the fabric member CM may be configured to hang down from the flat outer edge of the pad PD and form an inverted frustoconical shape when the bedding pad 100 is lifted with the top surface of the pad PD facing upwards. In other words, the fabric member CM may be configured to form an inverted frustoconical cylinder.

[0066] This configuration allows the fabric component CM, made of stretch fabric, to properly tighten the sides of the bedding (such as a mattress MT) even when the bedding is relatively thin. Therefore, the bedding pad 100 can prevent the pad PD, which is placed on the surface of the bedding, from sliding on the surface of the bedding, even when the bedding is relatively thin.

[0067] Furthermore, the bedding pad 100 may have an annular elastic member EC, as shown in Figure 2. In this case, the inner edge of the fabric member CM may be sewn to the elastic member EC. For example, the inner edge of the fabric member CM may be sewn to the outer edge of the elastic member EC. The annular elastic member EC is, for example, an elastic member in which the outer circumference is greater than the inner circumference is greater than the inner circumference.

[0068] This configuration allows the bedding pad 100 to increase the tightening force applied to the bedding (mattress MT, etc.) by the fabric member CM made of stretch fabric. This is because it suppresses the spreading of the inner edge of the fabric member CM.

[0069] Furthermore, the fabric member CM may be formed from a single strip of fabric as shown in Figure 3, and as shown in Figure 5, one of the two long sides of the single strip of fabric may be sewn to the outer edge of the pad PD, and the other may be sewn to the elastic member EC.

[0070] This configuration has the effect of reducing the manufacturing cost of the bedding pad 100. This is because, by using a single strip of fabric, it becomes possible to form a ring-shaped fabric member CM without creating any waste.

[0071] Furthermore, the elastic member EC may be formed from a strip of flat rubber, with one of its two long sides sewn to the fabric member CM. In this case, the bedding pad 100 may be configured such that the length of the elastic member EC is less than half the length of the fabric member CM.

[0072] This configuration has the effect of reducing the manufacturing cost of the bedding pad 100. By using a strip of flat elastic, it becomes possible to easily sew together strips of stretch fabric and strips of flat elastic of different lengths using a sewing machine, and consequently, it becomes possible to sew the outer edge of the stretch fabric (cloth material CM), whose inner edge is sewn to the flat elastic, to the pad PD.

[0073] Furthermore, the bedding pad 100 may be configured such that the outer circumference of the elastic member EC in its maximum stretched state is less than or equal to the outer circumference of the pad PD.

[0074] This configuration allows the bedding pad 100 to accommodate bedding (such as a mattress MT) while also increasing the tightening force applied to the bedding (such as a mattress MT) by the fabric member CM made of stretch fabric. This is because it suppresses the spreading of the inner edge of the fabric member CM.

[0075] Furthermore, the bedding pad 100 may be configured to be attached to bedding in other columnar shapes other than rectangular prisms, such as cylindrical, triangular prism, pentagonal prism, or elliptical prism.

[0076] Preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described above. Various modifications and substitutions can be applied to the embodiments described above without departing from the scope of the present invention. Furthermore, each of the features described with reference to the embodiments described above may be combined as appropriate, as long as they do not conflict technically.

[0077] For example, in the above embodiment, the bedding contained in the bedding pad 100 is a mattress MT, but it may also be a pillow, cushion, or seat cushion. [Explanation of Symbols]
