Description

[Technical Field]

[0001] This invention relates to a back cushion for a rug, which can be placed on the edge of a rug that is laid on part of the floor of a room, and can form a floor-low sofa with a backrest on the edge of the rug. In this invention, the term "rug" is used to include small mats and cushions such as cushions for sitting and sleeping. [Background technology]

[0002] Rug mats M are relatively small rugs that are used to cover only part of a room's floor, rather than the entire floor. In recent years, rug mats M with integrated backrests, such as the one shown in Fig. 9, which have backrest cushions 21 attached to the edges of thick rug mats 20 to support the lower back and back, have been sold by various companies under names such as floor low sofas and low sofas, and have become popular because they are relaxing and reduce fatigue even when sitting for long periods of time (for example, Non-Patent Document 1).

[0004] Conventional floor-low sofas have multiple back cushions 21 arranged along the edge of a rug M. To prevent the back cushions 21 from slipping when leaning against them, fasteners 22 are installed on the edge of the rug M and the front lower edge of the back cushions 21, as shown in Figure 10, and the edge of the rug M and the front lower edge of the back cushions 21 are connected and fixed by the fasteners 22.

[0005] However, in the case of a floor-low sofa in which the edge of the rug M and the front lower edge of the backrest cushion 21 are connected and fixed with a fastener 22, the sofa is a specially designed product in which the edge of the rug M and the front lower edge of the backrest cushion 21 are each provided with a fastener 22. For this reason, even if the backrest cushion 21 is placed on another rug M that does not have a fastener 22, the rug M and the backrest cushion 21 cannot be connected and fixed, and when a person sits leaning against the backrest cushion 21, the backrest cushion 21 may slip.

[0006] Therefore, the backrest cushion 21 of the type that is connected by the fastener 22 can only be installed on a specific rug mat M that is a specially designed product, and cannot be installed on any rug mat M.

[0007] Therefore, this invention aims to provide a backrest cushion that can be placed on the edge of not only specific rug mats but also various types of rug mats, and that will not slip even when you sit and put your weight on the back. [Means for solving the problem]

[0008] In order to solve the above problem, this invention is a backrest cushion that is installed on the edge of a rug mat to form a floor-low sofa, and is characterized by having an area that can at least support the vertical load of a user sitting and leaning against the backrest cushion, and a slip-prevention sheet that is sandwiched between the underside of the edge of the rug mat and the floor surface and protrudes forward from the underside of the backrest cushion.

[0009] The anti-slip portion may be provided in a dotted pattern on the entire front and back surfaces of the anti-slip sheet.

[0010] The shape of the backrest cushion portion is a linear I-shape in a plan view along the edge of the rug mat, or an L-shape in a plan view along the corner of the edge of the rug mat. [Effects of the Invention]

[0011] As mentioned above, the back cushion of this invention is configured so that the anti-slip sheet sandwiched between the underside of the edge of the rug and the floor surface protrudes forward from the underside of the back cushion and has an area large enough to support at least the vertical load of a user sitting and leaning against the back cushion. Therefore, even if the user leans against the back cushion, the user's vertical load is applied to the anti-slip sheet, so the back cushion does not slip relative to the rug, and the sofa can be installed on various rugs to create a floor-low sofa.

[0012] By providing anti-slip portions in a dotted pattern on the entire front and back surfaces of the anti-slip sheet, the anti-slip effect can be further improved. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0015] FIG. 1 is a perspective view showing an example of a backrest cushion 10 according to the present invention.

[0016] The backrest cushion 10 in Figure 1 is intended to be placed along the side edge of a rug mat M when constructing a floor-low sofa such as that shown in Figure 6, and is provided with a backrest cushion portion 11 that is I-shaped when viewed from above.

[0017] In addition, the backrest cushion 10 in Figure 3 is intended to be placed along the corner of a rug mat M when constructing a floor-low sofa such as that shown in Figure 6, and is provided with a backrest cushion portion 11 that is L-shaped when viewed from above.

[0018] The backrest cushion 10 is provided with a slip-prevention sheet 12 that protrudes forward from the underside of the backrest cushion portion 11. When the backrest cushion 10 is placed on a rug M, the slip-prevention sheet 12 is sandwiched between the underside of the edge of the rug M and the floor surface A, and its area may be large enough to support at least the vertical load of a user B sitting with their back weight applied to the backrest cushion portion 11, as shown in Fig. 4. For example, in the case of an I-shaped backrest cushion portion 11, the slip-prevention sheet 12 protrudes approximately 40 cm from the front edge of the underside of the backrest cushion portion 11, and in the case of an L-shaped backrest cushion portion 11, the slip-prevention sheet 12 protrudes approximately 49 cm diagonally from the front edge of the underside.

[0019] As shown in FIG. 2, the backrest cushion portion 11 can be formed by stacking, for example, a triangular cushion 11a having a triangular cross section and an arc-shaped cushion 11b having an arc-shaped front surface one on top of the other.

[0020] Both the triangular cushion 11a and the arc-shaped cushion 11b are formed by stuffing a cushioning material such as urethane into a fabric outer cover. The triangular cushion 11a uses, for example, block-shaped triangular urethane, while the arc-shaped cushion 11b uses, for example, chip urethane.

[0021] Furthermore, the fabric of the outer cover of the triangular cushion 11a and the arc-shaped cushion 11b can be made of a material that feels soft to the touch, such as flannel.

[0022] The anti-slip sheet 12 has a basis weight of 180 g / m 2 It can be formed by a nonwoven fabric of a certain degree.

[0023] As shown in Fig. 5, it is desirable to provide anti-slip portions 13 in a dotted pattern on the front and back surfaces of the anti-slip sheet 12. The anti-slip portions 13 can be made of a non-slip material such as PVC (polyvinyl chloride), silicone rubber, or TPR (thermoplastic rubber).

[0024] Next, Figure 6 shows an example of a floor-low sofa constructed by placing two I-shaped backrest cushions 10 shown in Figure 1 next to the L-shaped backrest cushion 10 shown in Figure 3, and placing a rug mat M on each of the anti-slip sheets 12.

[0025] When the backrest cushions 10 are installed side by side in this manner, it is desirable to lay a connecting belt 14 between the underside of the adjacent backrest cushions 10 and the floor surface A to connect them together, as shown in Figures 7 and 8, in order to prevent the adjacent backrest cushions 10 from shifting relative to each other.

[0026] The connecting belt 14 has hook-and-loop fasteners 14a along both sides of its surface, and a mating hook-and-loop fastener 14b that adheres to the hook-and-loop fasteners 14a is provided on the underside of the backrest cushion 10.

[0027] As described above, the backrest cushion 10 according to this invention has a slip-prevention sheet 12 that is sandwiched between the underside of the edge of the rug M and the floor surface A, and the slip-prevention sheet 12 protrudes forward from the underside of the backrest cushion portion 11 and has an area that can at least support the vertical load of user B sitting and leaning against the backrest cushion portion 11. Therefore, even if the user B leans back against the backrest cushion portion 11, the vertical load of user B is applied to the slip-prevention sheet 12, so the backrest cushion portion 11 does not slip relative to the rug M, and the sofa can be installed on various rugs M to form a low-floor sofa.
