Description

This disclosure relates to a mattress cover.

The mattress sheet disclosed in Patent Document 1 has a surface portion that covers the surface of the mattress, and a back portion that covers the sides and periphery of the back of the mattress.

Patent No. 7001894

When fitting a mattress cover used as a mattress sheet to a mattress, the mattress cover is usually wrapped around the four side surfaces of the mattress to the back surface so that the entire front and side surfaces of the mattress are covered by the mattress cover. To do this, the user must insert the four ends of the mattress cover under the mattress while successively lifting the ends of the mattress.

However, lifting a large, heavy mattress is a strenuous task for the user, and inserting the four edges of the mattress cover under the mattress by one person is extremely difficult. In particular, mattresses are often placed against a wall, and the space between the mattress and the wall is very limited, and in some cases, almost nonexistent. Passing the edges of the mattress cover through the limited space between the mattress and the wall and around to the underside of the mattress is a task that places a great physical and psychological burden on the user.

This disclosure has been made in consideration of the above circumstances, and aims to provide a technology that is useful for easily attaching a mattress cover to a mattress.

One aspect of the present disclosure relates to a mattress cover comprising a surface portion for covering a front side of a mattress, and an extension portion extending from the surface portion to surround the surface portion and having elasticity, wherein the extension portion includes a first extension portion and a second extension portion for covering, respectively, a first side side and a second side side of the mattress located on opposite sides across the front side, and when the mattress cover is attached to the mattress, the first extension portion covers the first side side and partially covers the back side of the mattress, and the second extension portion at least partially covers the second side side but does not cover the back side when stretched.

The extensions include a third extension and a fourth extension for at least partially covering a third side surface and a fourth side surface of the mattress located on opposite sides of the front surface, respectively, and the joining distance between the second extension and each of the third extension and the fourth extension may be shorter than the joining distance between the first extension and each of the third extension and the fourth extension.

The extensions include a third extension and a fourth extension for at least partially covering the third and fourth side faces of the mattress located on opposite sides of the front side, and the extensions have an edge portion that defines an opening, and when the mattress cover is attached to the mattress, at least a part of the edge portion of the first extension extends along the back side face, the edge portion of the second extension extends along the second side face, the edge portion of the third extension extends along the back side face and the third side face, and the edge portion of the fourth extension extends along the back side face and the fourth side face.

The surface portion and the extension portion may be made of a single type of fabric material.

The technology disclosed herein allows the mattress cover to be easily attached to the mattress.

Figure 1 is a plan view showing an example of a mattress cover 10. Figure 2 is a plan view showing the state of the fabric material of the mattress cover 10 before sewing.

Figure 3 is a perspective view showing an example of a mattress set 1. Figures 4 to 7 are side views of the mattress set 1 shown in Figure 5 as viewed in the directions of arrows "IV", "V", "VI" and "VII". Figure 8 is a top view of the mattress set 1 shown in Figure 5. Figure 9 is a bottom view of the mattress set 1 shown in Figure 5.

As shown in Figures 3 to 9, the mattress set 1 comprises a mattress 50 and a mattress cover 10 that is attached to the mattress 50.

The mattress 50 has a rectangular parallelepiped mattress body 57 and a number of mattress legs 58 (in this example, four mattress legs 58 attached to each of the four joints of the bottom) attached to the bottom of the mattress body 57. The mattress body 57 has a front side 51 on which the user is expected to lie, a back side 52 located opposite the front side 51, and a first side surface 53 to a fourth side surface 56 extending in the height direction between the front side surface 51 and the back side surface 52. The adjacent surfaces of the mattress body 57 do not strictly intersect at a right angle, and in this example, are connected to each other via a curved surface. The mattress legs 58 may not be provided, in which case the mattress 50 may be composed of only the mattress body 57.

The mattress cover 10 comprises a surface portion 11 for covering the rectangular front side surface 51 of the mattress body portion 57, and an extension portion 12 extending from the surface portion 11 so as to surround the surface portion 11. In the mattress cover 10 of this example, both the surface portion 11 and the extension portion 12 are made of a single type of fabric that is highly stretchable and elastic, and the surface portion 11 and the extension portion 12 extend integrally, continuously, and without interruption. The mattress cover 10 can be made of any fabric, such as a terry cloth that has excellent touch and sweat absorption properties, and the entire mattress cover 10 or a part of it may be made of a so-called seamless fabric.

The stretch rate of the mattress cover 10 is not limited. As an example, the mattress cover 10 may be elastically (reversibly) stretchable up to a maximum size of about 1.2 to about 3 times (e.g., about 1.5 to about 2 times) based on the size of the mattress cover 10 in its natural state (i.e., a state in which no active external force is applied).

The mattress cover 10 may include multiple types of fabric. As an example, the surface portion 11 and the extension portion 12 of the mattress cover 10 may each be made of different fabrics with different characteristics. For example, the surface portion 11, which is in direct contact with the user lying on the mattress set 1, may be made of a fabric with excellent touch and sweat absorption, while the extension portion 12 may be made of a fabric with excellent other characteristics (e.g., durability, elasticity, slip prevention against the mattress main body portion 57, and/or design). Therefore, the surface portion 11 may be made of a fabric with relatively poor elasticity, and each of the extension portions 12 may be made of a fabric with relatively high elasticity (i.e., a fabric with greater elasticity than the surface portion 11). For example, the surface portion 11 may be made of a quilted fabric, and each of the extension portions 12 may be made of a fabric other than the quilted fabric. Also, each of the surface portion 11 and the extension portion 12 may include multiple types of fabric with different characteristics. As an example, the outer surface of the surface portion 11 and/or the extension portion 12 that is exposed to the outside and the inner surface that faces the mattress main body portion 57 may be made of different fabrics.

The surface portion 11 in this example has a generally rectangular planar shape, but may have any shape and size. When the mattress cover 10 is attached to the mattress 50, it is preferable that the surface portion 11 of the mattress cover 10 adheres closely to the front side 51 of the mattress 50 while forming an overall flat surface, from the standpoint of not disturbing the sleep of the user and from the standpoint of aesthetic beauty. The surface portion 11 of the mattress cover 10 in this example is smaller overall in size than the front side 51 of the mattress 50 in its natural state, and adheres closely to the front side 51 of the mattress 50 in its stretched state.

The extension 12 of the mattress cover 10 includes a first extension 13, a second extension 14, a third extension 15, and a fourth extension 16 extending in all directions from the surface portion 11. The first extension 13 and the second extension 14 are located on opposite sides of the surface portion 11 and are portions for covering the first side surface 53 and the second side surface 54 located on opposite sides of the front surface 51 of the mattress 50. The third extension 15 and the fourth extension 16 are located on opposite sides of the surface portion 11 and are portions for covering the third side surface 55 and the fourth side surface 56 located on opposite sides of the front surface 51 of the mattress 50.

Each of the first extension portion 13 to the fourth extension portion 16 is joined to the other adjacent extension portion to form the joint portion 17. Specifically, each of the first extension portion 13 and the second extension portion 14 forms the joint portion 17 together with each of the adjacent third extension portion 15 and the fourth extension portion 16. In this example, the joint portion 17 is formed by joining the extension portions together by sewing, but the extension portions may also be joined together by any other joining means such as adhesive.

The distance (seam distance) of the joints 17 between the second extension 14 and each of the third extension 15 and fourth extension 16 is shorter than the distance of the joints 17 between the first extension 13 and each of the third extension 15 and fourth extension 16. Therefore, as shown in FIG. 2, before the mattress cover 10 is sewn, each of the first extension 13 and second extension 14 has a rectangular planar shape, while each of the third extension 15 and fourth extension 16 has a trapezoidal planar shape.

The extension 12 has an edge 18 that defines an opening 19 (see FIG. 1). The opening 19 is used to pass the mattress body 57 when attaching or detaching the mattress cover 10 to the mattress 50. The shape of the opening 19 is not limited, and the opening 19 may have a natural circular shape, an oval shape (including egg-shaped, oval, and elliptical), a polygonal shape (e.g., triangular or rectangular), or any other shape. In the example shown in FIG. 1, the edge 18 is reinforced by sewing or the like, but such reinforcement treatment may not be applied to the edge 18. For example, when the mattress cover 10 (particularly the extension 12) is made of a fabric (e.g., a seamless fabric) that is inherently less likely to fray at the cut end, the edge 18 may be made of an unreinforced cut end of the fabric.

The size of the opening 19 in its natural state is generally smaller than the front side 51 and the back side 52 of the mattress 50. On the other hand, when the mattress cover 10 is stretched by applying a pulling force, the size of the edge portion 18 changes so that the size of the opening 19 becomes larger than the front side 51 and the back side 52 of the mattress 50. Therefore, when the mattress cover 10 is attached to the mattress body portion 57, the entire mattress body portion 57 can pass through the opening 19 of the mattress cover 10, and as a result, the mattress body portion 57 is positioned inside the mattress cover 10. Then, when the mattress cover 10 is attached to the mattress body portion 57, the pulling force on the mattress cover 10 is released, and the opening 19 becomes smaller, and as a result, a part of the extension portion 12 of the mattress cover 10 can be appropriately wrapped around the bottom of the mattress body portion 57.

When the mattress cover 10 is attached to the mattress 50, the extension 12 covers the first side surface 53 to the fourth side surface 56 and the back surface 52 of the mattress 50 as shown in Figures 3 to 9. That is, when the first extension 13 is stretched, it covers the entire first side surface 53 and partially covers the back surface 52. When the second extension 14 is stretched, it partially covers the second side surface 54 but does not cover the back surface 52. When the third extension 15 is stretched, it partially covers the third side surface 55 and partially covers the back surface 52. When the fourth extension 16 is stretched, it partially covers the fourth side surface 56 and partially covers the back surface 52.

Therefore, when the mattress cover 10 is attached to the mattress 50, at least a portion of the edge portion 18 of the first extension portion 13 extends along the back surface 52 of the mattress 50 (see FIG. 9). Meanwhile, the edge portion 18 of the second extension portion 14 extends entirely along the second side surface 54 of the mattress 50 (see FIGS. 3 and 5). The edge portion 18 of the third extension portion 15 extends along the back surface 52 and the third side surface 55, and the edge portion 18 of the fourth extension portion 16 extends along the back surface 52 and the fourth side surface 56 (see FIGS. 6, 7, and 9).

In this way, the extension 12 of the mattress cover 10 is wrapped around at least two adjacent joints of the rectangular back side 52 of the mattress main body 57, so that the mattress cover 10 can be stably attached to the mattress main body 57. In particular, by locating the portion of the extension 12 of the mattress cover 10 that extends along the back side 52 in the vicinity of the mattress foot 58, the mattress foot 58 can be used as a member that contributes to positioning the extension 12 and preventing misalignment.

The joints 17 are intended to be located at the side portions of the mattress 50 (particularly at the boundary between adjacent side surfaces) when the mattress cover 10 is attached to the mattress 50. The joints 17 between the first extension 13 and each of the third extension 15 and the fourth extension 16 can be stretched to be longer than the height distance of the mattress body 57 (i.e., the height distance between the front side 51 and the back side 52). On the other hand, the maximum stretch length of the joints 17 between the second extension 14 and each of the third extension 15 and the fourth extension 16 may be shorter than the height distance of the mattress body 57. The thickness (height distance) of the mattress body 57 generally available is about 10 cm to 40 cm, and is often about 20 cm to 30 cm. Therefore, it is preferable that the joints 17 between the first extension 13 and each of the third extension 15 and the fourth extension 16 are stretchable to be longer than 10 cm to 40 cm, and by being stretchable to be longer than 20 cm to 30 cm, a mattress cover 10 that can be used universally for many mattresses 50 can be provided. In addition, the maximum stretch length of the joints 17 between the second extension 14 and each of the third extension 15 and the fourth extension 16 may be shorter than 10 cm to 40 cm, or shorter than 20 cm to 30 cm.

As described above, with the mattress cover 10, the mattress cover 10 can be easily attached to the mattress 50 without having to wrap the second extension 14 of the mattress cover 10 around the back surface 52 of the mattress main body 57. In particular, even if the mattress 50 is placed along a wall surface, if the second extension 14 of the mattress cover 10 can be inserted between the wall surface and the mattress main body 57 (particularly the second side surface 54), the mattress cover 10 can be properly and easily attached to the mattress 50 without having to wrap the second extension 14 around the back surface 52 of the mattress main body 57.

In addition, by constructing the mattress cover 10 from a fabric with excellent elasticity, it is possible to stably attach the mattress cover 10 to the mattress 50 by utilizing the force of the mattress cover 10 trying to shrink when stretched. This is also advantageous for fitting the mattress cover 10 to the outer surface (e.g., the front surface 51) of the mattress 50. In addition, the size of the mattress cover 10 in its natural state can be reduced, allowing the mattress cover 10 to be distributed and stored in a compact state.

[Modification]
The mattress cover 10 may be subjected to any processing to add any function. As an example, a non-slip portion (e.g., a member having a large coefficient of friction) may be attached to the back surface of the mattress cover 10 that comes into contact with the mattress main body 57, and the non-slip portion may prevent the mattress cover 10 from shifting relative to the mattress main body 57.

It should be noted that the embodiments and modifications disclosed in this specification are merely illustrative in all respects and should not be construed as limiting. The above-described embodiments and modifications may be omitted, substituted, or modified in various forms without departing from the scope and spirit of the appended claims. For example, the above-described embodiments and modifications may be combined in whole or in part, and embodiments other than those described above may be combined with the above-described embodiments or modifications.
