Abstract
Description
[Technical field]
[0001] This invention relates to an island sofa. [Background technology]
[0002] Conventionally, various kinds of sofas are used according to the purpose and place of use. Among such sofas, for example, sofas having a backrest that allows a user to sit in a relaxing position are widely used (see Patent Document 1).
[0003] Sofa beds are also in use, which have a reclining backrest that can be folded down to make the seat and backrest flat and can be used as a bed (see Patent Document 2).
[0004] Furthermore, there is a so-called island sofa, which is a sofa placed away from the wall in a relatively large space such as a living room or a lounge.
[0005] An island sofa has no backrest and a wider seat than a regular sofa, so it has the advantage that it can be sat on from any direction, front, back, left or right, and multiple people can sit on it at the same time from each direction. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] JP 2024-063695 A [Patent Document 2] Utility Model Registration No. 3213825 Summary of the Invention [Problem to be solved by the invention]
[0007] While island sofas have the advantage of allowing multiple people to sit on them from multiple directions, they have the problem that when used at home, for example, the user cannot sit in a relaxed position because there is no structure for them to lean on.
[0008] Therefore, it would be preferable to have an island sofa that can be used as a normal island sofa, but can also be transformed into a shape that allows for more comfortable sitting according to the user's preferences.
[0009] The present invention has been made in consideration of the above-mentioned problems, and is a device that can be used to make people feel more comfortable. To provide an island sofa. [Means for solving the problem]
[0010] The present invention is characterized by being an island sofa comprising a seat portion having a rectangular shape in a plan view, a backrest portion having a rectangular shape in a plan view and configured to be reclined, which is connected to one end of the seat portion and can be adjusted in angle relative to the seat portion, a pair of rectangular pillar-shaped armrests that can be placed on the seat portion so that their position can be changed, and a back cushion that can be placed on the seat portion so that their position can be changed.
[0011] In the above device, it is preferable that the length of the armrest in the longitudinal direction is the same as the length of the seat portion in the lateral direction. As a result, when they are disposed at both longitudinal ends of the seat, they function as arm rests for the sofa seat.
[0012] In the above device, it is preferable that the armrest has a trapezoidal cross-sectional shape. As a result, the armrest is more comfortable to sit on, allowing for stable use when the arm is placed on it.
[0013] In the above device, it is preferable that a weight portion is built into the bottom of the armrest. When the weight portion is built-in, the armrest can be placed in any suitable position on the seat and used, but no matter where it is placed, since the weight portion is built-in inside, it will not easily move from the position where it is placed and can fully withstand the weight of the user placed on it. As a result, even when used as an island sofa, the user can comfortably lean on the armrests and relax, making it possible to use the sofa in a variety of configurations.
[0014] In addition, in the above device, it is preferable that bonnell coils are built into the seat and backrest, and when the backrest is reclined, the upper surfaces of the seat and backrest become flush with each other, so that the device can be used as a bed. As a result, since it contains coils similar to those found in ordinary beds, it is highly cushioned and the user can lie down by reclining the backrest so that it is flush with the seat, allowing it to be used as a so-called daybed.
[0015] In addition, in the above device, it is preferable that the back cushion is formed in a flat rectangular shape, and the length of the short side of the back cushion is formed longer than the height of the backrest when the backrest is in an upright position.
[0016] It is also preferable that the sum of the short-side length of the pair of armrests and the longitudinal length of the back cushion is equal to the longitudinal length of the seat portion. As a result, when used in the form of a normal reclining sofa, the user can be adequately supported from the back, and armrests can be appropriately positioned at both longitudinal ends of the seat, providing a sofa on which the user can relax. Effect of the Invention
[0017] The island sofa according to the present invention described above can be used as a normal island sofa, and can also be transformed into a more comfortable shape according to the user's preference. Since the backrest is configured to be reclining, it can be used as a normal reclining sofa by adjusting the reclining angle of the backrest, or it can be used as an island sofa by completely reclining the backrest so that it is flush with the seat. When the backrest is upright, the problem of not being able to relax as with typical island sofas because there is no place to lean against it is eliminated. Furthermore, in this device, since bonnell coils are built into the seat and backrest, the user can lie down on it, and the comfort is no less than that of a regular bed. Therefore, since it can also be used as a daybed, it is possible to provide an island sofa that is versatile and can be used in multiple ways. [Brief description of the drawings]

[Figure 4] This is a photograph showing an island sofa according to an embodiment of the present invention in a state where the backrest is reclined and used as a daybed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Hereinafter, an embodiment of the island sofa according to the present invention will be described with reference to the drawings. Fig. 1 is a photograph of the island sofa 1 according to the embodiment of the present invention, with the reclining backrest 22 in an upright position and the armrest 3 and back cushion 4 in place. Fig. 2 is a photograph of the island sofa 1 according to the embodiment of the present invention, with the reclining backrest 22 in a reclined position and the armrest 3 and back cushion 4 in place. Fig. 3 is a photograph of the island sofa 1 in Fig. 2, with the armrest 3 and back cushion 4 in a different position. As shown in FIGS. 1 to 3, the island sofa 1 includes a sofa body 2, armrests 3, and a back cushion 4.
[0020] The sofa main body 2 comprises a seat portion 21, a backrest portion 22 that can be reclined relative to the seat portion, a bottom plate portion 23 to which the bottom surface of the seat portion 21 is fixed and which supports the seat portion 21 and the backrest portion 22, and legs (not shown) provided on the bottom side of the bottom plate portion 23.
[0021] The seat portion 21 has a rectangular shape in a plan view, and has a bonnell coil built therein.
[0022] The backrest 22 has a rectangular shape in a plan view, and contains a bonnell coil similar to that of the seat 21. The backrest 22 is provided continuous with the seat 21 via a connecting part J at one end of the seat 21 (the end side on the far side of the paper in Figs. 1 to 3), and the angle of the backrest 22 with respect to the seat 21 can be adjusted and the selected angle can be maintained by a reclining mechanism (not shown). In other words, the reclining mechanism enables the backrest portion 22 to maintain any angle between a reclined state relative to the seat portion 21 (a state in which the bottom of the backrest portion 22 abuts against the bottom plate portion 23) and a state in which the backrest portion 22 is approximately perpendicular to the seat portion 21.
[0023] As shown in FIG. 1, when the backrest 22 is in the upright position, the user can lean against the backrest 22, allowing the island sofa 1 to be used in a more relaxed manner.
[0024] 2 or 3, when the backrest 22 is reclined, the upper surface of the seat 21 and the upper surface of the backrest 22 are configured to be substantially flush with each other. Therefore, when the backrest 22 is reclined, the island sofa 1 can be used in such a manner that it can be sat on from any direction.
[0025] The bottom plate portion 23 is a plate-like member that is fixed to the bottom surface of the seat portion 21 using any fixing means such as a bolt, and when the backrest portion 22 is reclined as shown in Figure 3, it supports the base end side of the bottom of the backrest portion 22 and plays a role in keeping the upper surfaces of the seat portion 21 and the backrest portion 22 flush with each other. Furthermore, because of the presence of the bottom plate portion 23, even when the backrest portion 22 of the island sofa 1 is reclined and a user sits on the backrest portion 22, excessive load is applied to the connection portion J between the seat portion 21 and the backrest portion 22 and the reclining mechanism, and damage to these parts can be prevented.
[0026] The legs (not shown) are columnar members attached to the four corners of the bottom side of the bottom plate 23 using any fixing means such as bolts, and serve to support the entire island sofa 1. The number, shape, height and mounting position of the legs are optional. The provision of the legs creates a gap between the underside of the island sofa 1 and the floor, improving ventilation and making it easier to clean the floor.
[0027] The armrest 3 is prismatic and has a trapezoidal cross section in this embodiment. That is, the bottom surface 31 of the armrest 3 is wider than the top surface 32, and is tapered toward the top end, with the side surfaces 33 being inclined. In this way, the side surface 33 of the armrest 3 is inclined, so that the user can lean on the side surface 33 in a relaxed position. Also, because the bottom surface 31 is wider than the top surface 32, the armrest 3 is placed in a stable state, and is less likely to slip even when the user leans on it, and the aesthetic appearance quality of the sofa can be ensured.
[0028] A weight (not shown) is built into the bottom surface 31 side (bottom) of the armrest 3. By incorporating the weight, when the armrest 3 is placed on the seat 21 or the backrest 22 in the reclined position and used, it is possible to prevent the armrest 3 from slipping even when the user leans against it. Furthermore, when used as an island sofa, no matter where it is placed, the lower part of the armrest 3 is stable, so it can be placed stably while maintaining its posture.
[0029] The longitudinal length of the armrest 3 is the same as the lateral length of the seat 21. By making the longitudinal length of the armrest 3 the same as the lateral length of the seat 21, it becomes possible for the user to easily lean against the armrest 3 regardless of the position in which the user sits on the seat 21 when the backrest 22 is upright, i.e., whether the user sits shallowly or deeply. Furthermore, by making the longitudinal length of the armrest 3 the same as the lateral length of the seat 21 when the backrest 22 is in the upright position, a sense of unity and unity is created between the sofa body 2 and the armrest 3 placed on the seat 21, resulting in an excellent aesthetic appearance as a sofa.
[0030] Any material and surface material can be used for the armrest 3, but by incorporating an elastic material such as cotton or sponge inside the armrest 3, the user can feel more comfortable when leaning against the armrest 3. The armrest 3 is also formed so that it can be used with any cover.
[0031] In this embodiment, the back cushion 4 is composed of two cushions: a small cushion 41 having a rectangular shape in a plan view, and a large cushion 42 which is larger than the small cushion 41 and also has a rectangular shape in a plan view.
[0032] Both the small cushion 41 and the large cushion 42 contain elastic materials such as cotton, sponge, etc. inside. This makes it easier for a user to relax when the small cushion 41 and the large cushion 42 are leaned against the backrest 22 in an upright position. The surface materials of the small cushion 41 and the large cushion 42 may be any material, and they are also formed so that they can be used with a cover.
[0033] In addition, by providing two types of back cushions 4, a small cushion 41 and a large cushion 42, it is possible to enjoy different looks, and it is possible to adjust the arrangement of the back cushions 4 and the type of back cushion 4 to be used according to the sitting posture and the number of people, thereby achieving better sitting comfort. However, in the present invention, the back cushion 4 is not limited to the small cushion 41 and large cushion 42 of this embodiment, and may be composed of, for example, two or more cushions of the same size, or may be composed of a single cushion.
[0034] Further, the length of the short side of the back cushion 4 (the length of the small cushion 41 and the large cushion 42 in the vertical direction on the paper in FIG. 1) is longer than the height of the backrest 22 when the backrest 22 is in the upright position. As a result, when the back cushion 4 is leaned against the upright backrest 22, the user's back will not come into contact with the corners at the upper end of the upright backrest 22, making the seating more comfortable.
[0035] The island sofa 1 described above can be shaped in various ways to suit the preferences of the user by adjusting the angle of the backrest 22 and the arrangement of the armrests 3 and the back cushion 4.
[0036] For example, the armrest 3 can be placed along the short side of the seat 21 at both ends of the seat 21 as shown in Figure 1, but is not limited to this and can be placed at any position on the seat 21 at any angle as shown in Figures 2 and 3.
[0037] Moreover, the back cushion 4 can be used not only by leaning it against the backrest portion 22 as shown in FIG. 1, but also by leaning it against the armrest 3 as shown in FIGS.
[0038] Fig. 4 is a photograph showing the island sofa 1 according to the embodiment of the present invention being used as a daybed with the backrest 22 reclined. As shown in Fig. 4, when the backrest 22 of the island sofa 1 is reclined, the upper surface of the seat 21 and the upper surface of the backrest 22 become flush with each other. Furthermore, the seat 21 and backrest 22 have built-in bonnell coils, providing good cushioning as a bed. Therefore, the island sofa 1 can also be used as a bed where the user U can stretch his / her legs and sleep comfortably. In this case, the back cushion 4 (here, the large cushion 42) can also be used as a pillow, as shown in FIG. 4.
[0039] According to the island sofa 1 of this embodiment described above, it can be used as a normal island sofa by reclining the backrest 22, and can also be transformed into a more relaxing shape according to the user's preference. Furthermore, the island sofa 1 of this embodiment can also be used as a bed when the backrest 22 is reclined.
[0040] The present invention is not limited to the above-described embodiment, and any modifications can be made without departing from the technical scope of the invention.
[0041] For example, in the above embodiment, the armrest 3 has a trapezoidal cross section, but the present invention is not limited to this, and the armrest 3 may have a square or rectangular cross section. Also, in the above embodiment, two armrests 3 are used, but the present invention is not limited to this, and one, three or more armrests 3 may be used depending on the size of the island sofa 1 and the expected number of people seated on it.
[0042] In addition, although the legs are simply columnar members in this embodiment, the present invention is not limited to this, and casters may be provided on the lower end of the columnar part. By providing casters on the tip of the legs, the island sofa 1 can be easily moved. In addition, when providing casters, it is preferable for safety reasons that they have a locking mechanism that locks the rotation of the casters. [Explanation of symbols]
