Description

[Technical field]

[0001] This invention relates to a sofa that allows you to relax in a variety of positions. [Background technology]

[0002] For example, a long, two-seater sofa is known that has a seat on which a user sits, a backrest connected to the rear end of the seat, and left and right armrests connected to the left and right ends of the seat so that they can be raised and lowered (reclined).

[0003] [Non-Patent Document 1] [Retrieved December 9, 2024], Internet<URL;https: / / store.shopping.yahoo.co.jp / livingut / 408341.html> Summary of the Invention [Problem to be solved by the invention]

[0004] Although such conventional sofas are generally used as two-seaters, they are often used by one person to lie down on the sofa, taking advantage of their long width and reclining function. In this case, the user would relax by tilting the left and right armrests to their preferred angle. However, in recent years, there has been an increasing demand from new users who prefer a so-called "lazy" posture and who find that simply reclining the left and right armrests is not enough to relax.

[0005] Therefore, after extensive research, the inventor discovered that by dividing the seat into three parts, the left partial seat part, the central partial seat part, and the right partial seat part, in addition to adding a reclining function to the left and right armrests, it would be possible to meet these new user demands, and thus completed the present invention.

[0006] The present invention has been made in consideration of the problems in the past, and aims to provide a sofa that allows users to relax in various positions according to their preferences. [Means for solving the problem]

[0007] The invention described in claim 1 is a sofa comprising a seat portion on which a user sits, a backrest portion connected to the rear end of the seat portion, a left armrest portion connected to the left end of the seat portion so as to be able to rise and fall, and a right armrest portion connected to the right end of the seat portion so as to be able to rise and fall, wherein the seat portion is divided into three portions: a left partial seat portion to which the left armrest portion is connected, a central partial seat portion, and a right partial seat portion to which the right armrest portion is connected, and the left partial seat portion is connected to the left end of the central partial seat portion so as to be able to rise and fall, and the right partial seat portion is connected to the right end of the central partial seat portion so as to be able to rise and fall.

[0008] The type of sofa is not limited as long as it is a reclining type. For example, it may be a one-seater or a two-seater or more. A sofa has a main body frame that serves as a core (framework), a main body cushion that covers the main body frame, and a main body cushion cover that covers the main body cushion.

[0009] The materials, shapes, sizes, etc. of the seat, backrest and armrests are all optional. The means for enabling the left and right armrests and the left and right seat portions to be raised or lowered is not limited. For example, an angle adjustment tool having a ratchet structure with a predetermined number of steps may be used. The seat portion may or may not be divided into three equal portions: a left partial seat portion, a center partial seat portion and a right partial seat portion. A number of support legs may be fixed or hooked to the underside of the seat.

[0010] The invention described in claim 2 is the sofa described in claim 1, characterized in that the backrest portion is connected to the seat portion so that it can be raised and lowered. The means for enabling the backrest to be raised or lowered is not limited, and may be, for example, an angle adjustment tool having a ratchet structure with a predetermined number of stages.

[0011] The invention described in claim 3 is the sofa described in claim 1 or 2, characterized in that a plurality of support legs are detachably disposed on a base to which the central seat portion is fixed.

[0012] The base may have any configuration, for example, a flat plate or a frame having a predetermined shape covered with a cover. The support legs can be made of various materials such as wood, plastic, and metal. The height of the support legs is arbitrary. For example, it may be 15 cm or more so that a robot vacuum cleaner can pass through. Effect of the Invention

[0013] In the sofa of this invention, in addition to the reclining function of the left and right armrests, the seat is divided into three parts, left and right partial seat sections and a central partial seat section, and a reclining function is also added to the left partial seat section to which the left armrest is connected and the right partial seat section to which the right armrest is connected.

[0014] As a result, for example, when a user wants to lie down on the sofa, the left and right armrests can be tilted and the seat part that is closest to the user's head can be raised diagonally, allowing the user to relax by using the armrest and seat part on the inclined side as a backrest. In this case, since both the left and right seat parts of the seat can be raised and lowered, the user can adjust the direction of their head relative to the sofa to suit their changing preferences.

[0015] Also, for example, if you want to raise your legs while lying on your side, you can do so by tilting the seat part on the foot side.

[0016] In particular, according to the present invention described in claim 2, a reclining function has been added to the backrest, so that, for example, the user can lie down on his / her side on the sofa and place his / her feet on the tilted backrest to assume an even more relaxed position.

[0017] In addition, according to the present invention described in claim 3, a plurality of support legs are detachably arranged on the base to which the central seat portion is fixed, so that the sofa can be changed to one with legs or placed directly on the floor depending on the user's mood.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] An embodiment of the present invention will now be described in detail. EXAMPLES

[0020] As shown in Figures 1 and 2, sofa 10 according to embodiment 1 of the present invention is a long, horizontal reclining chair for two people, and includes a base 11 which is the main body of sofa 10 and has a horizontal, rectangular frame shape when viewed from above, a seat 12 on which a user sits, a backrest 13 which is connected to the rear end of seat 12 so that it can be raised and lowered, a left armrest 14 which is connected to the left end of seat 12 so that it can be raised and lowered, and a right armrest 15 which is connected to the right end of seat 12 so that it can be raised and lowered. These components will now be described in detail.

[0021] As shown in Fig. 3, the base 11 is made of large-diameter steel pipes with a horizontal length of 110 cm and a depth of 55 cm assembled into a rectangular frame in plan view and covered with a durian cloth cover, and four plastic support legs 17 are screwed to triangular brackets 16 arranged at the four corners via bolts and nuts. The height of each support leg 17 is 15 cm, allowing a robot vacuum cleaner (not shown) to pass through. In this way, since the four legs 17 are screwed to the base 11, the sofa 10 can be changed to one with legs or one that is placed directly on the floor according to the user's mood.

[0022] As shown in Figures 1 and 2, the seat 12 is divided into three equal parts in its length (horizontal) direction: a left seat portion 18 with the left armrest 14 connected to its left end, a central seat portion 19, and a right seat portion 20 with the right armrest 15 connected to its right end. Of these, the lower side of the central seat portion 19 is fixed to the longitudinal middle portion of the base 11. The left seat portion 18 is connected to the left end of the central seat portion 19 so as to be able to rise and fall, while the right seat portion 20 is connected to the right end of the central seat portion 19 so as to be able to rise and fall.

[0023] As shown in Figures 1 and 3, sofa 10 has a main body frame 21 which serves as the core material, a main cushion (not shown) which has polypropylene cotton and urethane foam and covers main body frame 21, and a six-mask quilt main cushion cover 22 made of polyester durian fabric which covers the main cushion.

[0024] The main body frame 21 is a steel pipe. The main body frame 21 has (1) a rectangular seat frame 23 that serves as the core of the seat 12, which is 110 cm long in the horizontal direction, 53 cm deep, and 14 cm thick, (2) a rectangular backrest frame 24 that serves as the core of the backrest 13, which is 110 cm long in the horizontal direction, 50 cm high, and 14 cm thick, and (3) relatively small rectangular left and right armrest frames 25, 26 that serve as the core of the left and right armrests 15, which are 53 cm long in the vertical direction, 30 cm high, and 9 cm thick.

[0025] Of these, the seat frame 23 has (1a) a central seat frame 27 in the middle in the longitudinal direction, (1b) a left seat frame 29 connected to the front and rear corners on the left side of the central seat frame 27 by a pair of front and rear first angle adjustment devices 28 having a ratchet structure so that it can be rotated (raised and lowered) in 14 steps in the left and right direction, and (1c) a right seat frame 30 connected to the front and rear corners on the right side of the central seat frame 27 by a pair of front and rear first angle adjustment devices 28 so that it can be rotated (raised and lowered) in 14 steps in the left and right direction.

[0026] In addition, the backrest frame 24 is connected to both longitudinal ends of the rear frame pipe 32 of the base stand 11 so as to be rotatable (raised and lowered) in five steps in the forward and backward (raised and lowered) directions by a pair of second angle adjustment devices 31 on the left and right sides, which also adopt a ratchet structure. Furthermore, the left and right armrest frames 25, 26 are also connected to the left and right seat partial frames 29, 30, respectively, by a separate pair of front and rear second angle adjusters 31 so as to be rotatable in five stages in the left and right direction.

[0027] Next, a method of using the sofa 10 according to the first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 2, in addition to the reclining function of the left and right armrests 14, 15, this sofa 10 has a reclining function added to the left partial seat portion 18 to which the left armrest 14 is connected, and the right partial seat portion 20 to which the right armrest 15 is connected, of the seat portion 12 which is divided into three parts: left and right partial seat portions 18, 20 and a central partial seat portion 19. In this way, since both the left and right partial seat portions 18, 20 of the seat portion 12 can be raised and lowered, the direction of the head relative to the sofa 10 can be adjusted to suit the user's preferences, which change from time to time.

[0028] A specific example of how the sofa 10 can be used will now be described. For example, as shown in Figures 1 and 3, when a user wants to lie down on the sofa 10, first, the left armrest 14 is tilted nearly to horizontal and the right armrest 15 is tilted to horizontal using the pair of second angle adjusters 31 on the left and right. After that, the left seat portion 18, which is the side of the user's head, is tilted up to about 30° using the first angle adjuster 28 on the left side. This allows the user to relax by leaning back against the inclined left armrest 14 and the left seat portion 18. Here, one of the two cushions 33 provided is used as a pillow, while the other is used as a hand rest.

[0029] Furthermore, as shown in Figures 3 and 4, when lying on one's side and raising both legs to relieve leg swelling or fatigue, the right armrest 15 can be adjusted to a horizontal position via the separate second angle adjuster 31 on the right side, and then the right seat portion 20, which is closest to the user's feet, can be tilted up to approximately 30° via the first angle adjuster 28 on the right side. Furthermore, as shown in Figures 3 and 5, when one wishes to sit sideways on the sofa 10 and stretch out one's legs, for example to operate a smartphone or read, one first tilts the left and right armrests 14, 15 horizontally using the separate second angle adjustment devices 31, and then tilts the left seat portion 18 to approximately 45° via the first angle adjustment device 28 on the left side.

[0030] Furthermore, as shown in Figures 3 and 6, when one wishes to lie down on the sofa 10 with one leg resting on the backrest 13, the left and right armrests 14, 15 and the left and right seat portions 18, 20 are adjusted to be horizontal by operating the corresponding angle adjusters 28, 31, and the backrest 13 is tilted diagonally via the second angle adjuster 31, thereby obtaining the above-mentioned posture.

[0031] 3 and 7, sitting facing forward on sofa 10 and leaning the upper half of the body against left armrest 14 and left seat 18, which are inclined at about 45 degrees by operating corresponding angle adjusters 28, 31, is suitable for watching television, for example. In this way, adding a reclining function to backrest 13 allows the user to take an even more relaxed posture. [Industrial Applicability]

[0032] This invention is useful as a sofa technology that allows you to relax in a variety of positions. [Explanation of symbols]
