Abstract
Description
[Technical field]
[0001] The present invention relates to a floor covering with a mat, in which a mattress is used as the base material for the floor covering. [Background technology]
[0002] In recent years, rugs that are laid on part of the living room floor have become known as a type of interior item sold at online shops, etc. A highly cushioned rug has a base mattress whose upper surface is covered with a surface fabric (upper cover), allowing users to sit or lie down on the rug to relax. The mattress for this rug is several centimeters thick. [Prior art documents] [Patent documents]
[0003] [Non-Patent Document 1] [Retrieved November 5, 2024], Internet<URL:https: / / item.rakuten.co.jp / homfine / hfjrg03 / > Summary of the Invention [Problem to be solved by the invention]
[0004] However, conventional rugs had mattresses that were only a few centimeters thick, so although users could sit or lie down on them, they were reluctant to use them as a mattress to sleep on, fearing that it could cause back or waist pain while sleeping. To solve this problem, it is conceivable to make the mattress as thick as a futon, for example. However, for rugs sold online like this, the thicker the mattress, the larger the package size will be, which will increase the cost of delivery and make them difficult to handle. These issues were also present with other types of floor coverings, such as rugs and carpets.
[0005] Therefore, after extensive research, the inventors came up with the idea of dividing a thick mattress, measuring 5cm to 20cm in thickness, into several partial mattress pieces when viewed in a plane, assembling the mattress by butting these together sequentially within a lower cover sized to cover the underside of the mattress, and then covering the top surface of the resulting mattress all at once with an upper cover. As a result, even though the rug is made of a thick mattress, the packaging shipped from the factory is compact, reducing transportation costs, and the handling and assembly of the mattress is also made easier, which is what led to the completion of this invention.
[0006] To provide a mat-attached rug that can reduce transportation costs by making the package compact despite having a thick mattress as a base material, and that can easily handle and assemble the mattress and the rug, and that does not cause back or waist pain while sleeping even if the rug is used as a futon because the mattress is thick. [Means for solving the problem]
[0007] The invention described in claim 1 is a mat-attached rug in which a mattress is used as a base material whose upper surface is covered by an upper cover, the mattress being 5cm to 20cm thick and divided into several partial mattresses when viewed in a plane, the underside of the mattress being covered by a lower cover, and the lower cover being bag-shaped and used to assemble and maintain the shape of the mattress by butting the ends of the partial mattresses together within the lower cover.
[0008] Here, "dividing the mattress into multiple partial mattress pieces when viewed in a plane" means cutting the mattress into multiple pieces that penetrate from the front to the back, rather than slicing the mattress into multiple pieces in the thickness direction. Here, "the lower cover is bag-shaped, and the ends of the partial mattresses are butted together within the lower cover to assemble and maintain the shape of the mattress" refers to, for example, a box-cover-like lower cover sheet with strings (including elastic strings) attached to the edges, which covers the entire underside of the mattress, along its peripheral side, and the outer periphery of the upper surface of the mattress. Alternatively, it may be a drawstring-like lower cover with a drawstring attached to the peripheral edge, which covers the entire underside of the mattress, along its peripheral side, and up to the center of the upper surface of the mattress.
[0009] The type of floor covering is not limited, and may be, for example, a rug, a carpet, or the like. The upper cover and the lower cover may be made of any fiber material, including, for example, various natural fibers (such as cotton, hemp, raw silk, silk thread, wool, cashmere, etc.) and various chemical fibers (polyester, nylon, acrylic, polyurethane, rayon, etc.). The fiber of the upper cover that comes into contact with the user is preferably fulled and brushed flannel.
[0010] The upper cover may be of any size, for example, it may be of a size that covers the entire upper surface of the mattress, along the peripheral side surfaces, and the outer periphery of the lower surface of the mattress. The size of the lower cover is also arbitrary, for example it may be a size that covers the entire lower surface of the mattress, along the peripheral side, and the outer periphery of the upper surface of the mattress. The shape of the upper cover is arbitrary. For example, it may be a flat sheet, or may be a box cover (fitted sheet) whose periphery is tightened with a string (including an elastic string) and which covers the entire upper surface of the mattress, through the peripheral side surface, and the outer periphery of the lower surface of the mattress.
[0011] A sheet-like mat layer of a predetermined thickness may be laminated on the lower side (inner side) of this upper cover. The shape of the lower cover is also arbitrary. For example, it may be in the form of a flat sheet, or in the form of a box cover (an upward-facing fitted sheet with the opening facing upward) whose periphery is tightened with a string (including an elastic string) and which covers the entire corresponding lower surface of the mattress, via the peripheral side surface, and the outer periphery of the upper surface of the mattress.
[0012] The mattress may be made of any material, such as urethane foam, latex foam, fiber, or fiber wadding. If the mattress is less than 5cm thick, the mattress (partial mattress) will be too thin, making it difficult to assemble the mattress by butting the ends of the partial mattresses together, and it will be difficult to sleep on the mat instead of using it as a futon.
[0013] Also, if the mattress thickness exceeds 20 cm, the mattress is too thick and it is difficult to walk on the mat. The preferred thickness of the mattress is 8 cm to 15 cm, and particularly preferably around 10 cm. If the thickness is within this range, it is possible to assemble the mattress by butting the ends of the partial mattresses together, and the user can sleep on the mat instead of a futon and walk comfortably on the mat.
[0014] The mattress and the partial mattress may each have any shape, for example, a rectangular shape, a circular shape, or the like. The mattress may be divided into any number of sub-mattresses, provided that the number is two or more. A partial mattress may be an equal or unequal division of the mattress.
[0015] In addition, as a mat with a mat, the mat may be a rectangular rug, the partial mattress may be the mattress divided into 4 to 8 equal rectangular pieces, the upper cover may be made of flannel fabric with a sheet-like mat layer having a thickness of 1 cm to 3 cm laminated on the underside, and the lower cover may have an anti-slip material on the underside that comes into contact with the floor.
[0016] In this way, the mattress, which is the base material of the rectangular rug, is made up of partial mattresses divided into 4 to 8 equal parts, so the mattress can be packed in a folded state to 1 / 4 to 1 / 8 of its size. In addition, the upper cover is made of a flannel fabric with a 1-3cm thick sheet-like mat layer laminated on the back, which makes the upper cover soft to the touch and allows the mattress to be thinner by the thickness of the sheet-like mat layer, which reduces the packaging size of the mattress.
[0017] In addition, since the sheet-like mat layer is thin, being 1 cm to 3 cm, this upper cover can also be packed compactly, for example, by rolling it up into a long and thin shape or folding it into a small size. Furthermore, anti-slip material is provided on the underside of the lower cover to prevent the mat from slipping when in use.
[0018] If the mattress is divided into less than four parts, the partial mattresses cannot be made small enough, making them difficult to handle and packing compactly. If the mattress is divided into more than eight parts, it becomes time-consuming to butt the ends of the partial mattresses together inside the lower cover to assemble the mattress.
[0019] Furthermore, if the thickness of the sheet-like mat layer is less than 1 cm, the cushioning properties of the upper cover are poor. If the thickness exceeds 3 cm, the upper cover becomes too thick and difficult to handle, and it is difficult to roll up and fold the cover, so that the upper cover may not be packed compactly. The preferable thickness of the sheet-like mat layer is about 2 cm. If the thickness is within this range, the upper cover can be given appropriate cushioning properties, and the upper cover can be easily handled and rolled up and folded, so that the upper cover can be packed compactly. The material of the anti-slip material is arbitrary. For example, various kinds of rubber can be used. The size and shape of the anti-slip material are also arbitrary. The anti-slip material may be applied to the entire lower surface of the lower cover, or only to a part of it.
[0020] In addition, the invention described in claim 2 is a mat-attached rug as described in claim 1, characterized in that the lower cover is a box cover whose peripheral edge is tightened with a string including an elastic string, and which covers the entire underside of the mattress, along the peripheral side surfaces, and the outer periphery of the upper surface of the mattress.
[0021] The type of string used to tighten the periphery of the lower cover is arbitrary. For example, it may be a rubber string or a general string with no elasticity (flexible wire strap). The string may be provided around the entire periphery of the lower cover, or only on a part of it (for example, each corner).
[0022] Furthermore, the invention described in claim 3 is a mat-attached rug described in claim 1 or claim 2, characterized in that the mattress has a two-layer structure having a thick mattress body which is divided into multiple partial mattress bodies when viewed in a plane, and a thin mat sheet which is placed on top of the mattress body which is assembled and held together from the multiple partial mattress bodies within the lower cover, and the peripheral portion of the lower cover is sandwiched between the mat sheet and the mattress body when the mat sheet is placed on top of the mattress body. The thickness ratio of the mattress body to the mat sheet can be any ratio, for example, 10:1 to 2:1. Effect of the Invention
[0023] According to the mat-attached rug of the present invention, a mattress with a thickness of 5 cm to 20 cm is divided into several partial mattresses when viewed in a plane. Therefore, even though the rug is made of a thick mattress as the base material, the packaging shipped from the factory is compact, thereby reducing transportation costs. In addition, when assembling the mat, the mattress is assembled by butting the ends of each partial mattress together within a lower cover sized to cover the underside of the mattress, and the upper surface of the resulting mattress is covered all at once with an upper cover. This makes it easy to handle and assemble the rug, even though it is made of a thick mattress. Also, because the mattress is so thick, you are less likely to get back or hip pain while sleeping on the rug instead of a futon.
[0024] In particular, according to the present invention described in claim 2, a box cover with a periphery that is tightened by a string including an elastic string is used as the lower cover, so that when assembling the mattress by butting multiple partial mattresses together in sequence in the inner space of the lower cover, the butted partial mattresses are pressed together by the outer periphery of the lower cover that is squeezed inward by the elasticity of the elastic string. This improves the shape retention of adjacent partial mattresses during assembly and of the mattress after assembly.
[0025] According to the present invention as set forth in claim 3, a two-layer structure mattress is adopted, which has a thick mattress body assembled and held in the lower cover, and a thin mat sheet placed on top of it. This allows the mattress to be folded or rolled up more compactly, and as a result, the package shipped from the factory becomes more compact, further reducing transportation costs. Moreover, since the mat sheet is superimposed on the mattress body divided into a plurality of partial mattress bodies, when the mattress is used, a part of the user's body does not sink into the gaps between adjacent partial mattress bodies, improving, for example, the comfort of sitting and stepping on the mattress.
[0026] In addition, by placing the mat sheet on the mattress body, the peripheral portion of the lower cover is sandwiched between the mattress body and the mat sheet, which makes it difficult for the lower cover to come off the mattress body when the upper cover is then placed over the mattress body with the lower cover from above the mat sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] An embodiment of this invention will now be described in detail. EXAMPLES
[0029] As shown in FIGS. 1 and 2, a rug with a mat (matted floor covering) 10 according to a first embodiment of the present invention uses a mattress 12 as a base material whose upper surface is covered by an upper cover 11. This rug with mat 10 is an extremely thick square rug with a thickness of about 10 cm, a length of about 200 cm, and a width of about 200 cm.
[0030] The mattress 12 has a two-layer structure comprising a thick mattress body 13 made of urethane foam, 8 cm thick, 200 cm long and 200 cm wide, and a thin mat sheet 14 made of urethane foam, 2 cm thick, 200 cm long and 200 cm wide. Of these, the mattress body 13 is divided vertically into two equal parts and horizontally into three equal parts, for a total of six equal parts, consisting of six horizontally long rectangular partial mattress bodies 15. These partial mattress bodies 15 are assembled within a lower cover 16 that covers the underside of the mattress body 13.
[0031] The upper cover 11 is made of flannel fabric and has its entire peripheral edge (entire periphery of the opening) tightened with a circular elastic cord 17, and is a box cover that covers the outer peripheral part of the lower surface of the mattress body 13 from the entire upper surface of the mattress body 13 through the peripheral side surfaces via the mat sheet 14. At the four corners of the upper cover 11, corner rubber cords 30 are arranged to hook the corresponding corners of the mattress body 13 covered by the lower cover 16 from below.
[0032] On the other hand, the lower cover 16 is made of cotton fabric and has its entire peripheral edge tightened by a circular elastic cord 18, forming a box cover that covers the entire lower surface of the mattress body 13, along the peripheral side surfaces, and the outer periphery of the upper surface of the mattress body 13. Additionally, a large number of dot-shaped anti-slip materials 19 made of a rubber material are fixed to the entire lower surface of the lower cover 16 (see FIG. 7). This makes it possible to prevent the mat-attached rug 10 from slipping during use.
[0033] Next, a method of using the mat-attached rug 10 according to the first embodiment of the present invention will be described with reference to Figs. As shown in Figures 3 and 4, when using the rug with mattress 10 of Example 1, first, the lower cover 16 is spread out on the floor with the opening facing up. After that, the six partial mattress bodies 15 are inserted one by one into the internal space of the lower cover 16 from the opening, and the ends of adjacent partial mattress bodies 15 are butted together inside the lower cover 16. This assembles the mattress body 13, which is divided vertically into two equal parts and horizontally into three equal parts.
[0034] At this time, a box cover whose entire periphery (opening) is squeezed by annular rubber cord 18 is used as the lower cover 16, so when the mattress body 13 is assembled from the six partial mattress bodies 15 in the space inside the lower cover 16, the butt ends of adjacent partial mattress bodies 15 are pressed together by the outer periphery of the lower cover 16 which is constantly squeezed inwards by the elastic force of the rubber cord 18. This improves the shape retention of adjacent partial mattress bodies 15 during assembly and of the mattress body 13 after assembly.
[0035] 5 and 6, the mat sheet 14 is placed on the assembled mattress body 13. At this time, the entire peripheral edge of the lower cover 16 is sandwiched between the mattress body 13 and the mat sheet 14. 1 and 2, the upper cover 11 is placed over the mattress body 13 with the lower cover 16 from above the mat sheet 14. As a result, the mattress body 13 with the lower cover 16 is covered by the upper cover 11 from the entire upper surface through the peripheral side surface to the outer peripheral portion of the lower surface of the mattress body 13 via the mat sheet 14. As a result, even though the mattress rug 10 is assembled using the thick mattress 12 as a base material, the handling and assembly of the rug 10 is easy. Also, because the mattress 12 is thick in this way, even if you sleep with the mattress rug 10 instead of a futon, your back and waist are less likely to hurt while sleeping.
[0036] Furthermore, when the upper cover 11 is placed over the mattress body 13 with the lower cover 16, the entire peripheral edge of the lower cover 16 is sandwiched between the mattress body 13 and the mat sheet 14. Therefore, when the mattress body 13 with the lower cover 16 is covered with the upper cover 11 from above the mat sheet 14 in this manner, the lower cover 16 is unlikely to come off from the mattress body 13.
[0037] Furthermore, the 10 cm thick mattress 12 has a two-layer structure having an 8 cm thick mattress body 13 and a 2 cm thick mat sheet 14, so the mattress 12 can be folded or rolled up more compactly. Moreover, since the mat sheet 14 is superimposed on the mattress body 13 divided into a plurality of partial mattress bodies 15, when the mattress is used, a part of the user's body does not sink into the gaps between the adjacent partial mattress bodies 15, improving, for example, the comfort of sitting and stepping on the mattress. Furthermore, since the mattress body 13 is equally divided into six partial mattress bodies 15, the packaging at the time of shipment from the factory can be made even more compact, further reducing transportation costs.
[0038] In addition, the mattress 12 used here has a two-layer structure, which includes a thick mattress body 13 assembled and held within a lower cover 16, and a thin mat sheet 14 placed on top of it. This allows the mattress 12 to be folded or rolled up more compactly, and as a result, the package shipped from the factory becomes more compact, further reducing transportation costs.
[0039] In this embodiment 1, such a two-layer structure is used as the mattress 12, but the present invention is not limited to this. For example, as shown in Fig. 8, a rug with a mat (matted carpet) 10A may be used instead of the mattress 12, which does not have a mat sheet 14 and is an extremely thick mattress 12A made of only one urethane foam sheet with a thickness of 10 cm, and this may be divided into a predetermined number of partial mattresses 15A in plan view. [Industrial Applicability]
[0040] This invention is useful as a technique for a matted rug in which a mattress is used as the base material for a floor covering. [Explanation of symbols]
