Description

[Technical field]

[0001] The present invention relates to a furniture for a sofa, to a sofa and to a sofa with furniture. [Background technology]

[0002] As living environments change, sofas have gone from being placed against the walls of rooms to being placed in the center of living and dining spaces. In addition, as lifestyles change, it is now common for family members to gather in the living room not only to watch TV together, but also for each person to enjoy watching their mobile phone or tablet individually. Reflecting this lifestyle, sofas are now designed so that people can sit on them in any direction and in any posture, rather than sitting side by side facing the TV.

[0003] One example is a flat bed mattress with no backrest or armrests, which allows the user to sit on it from any direction around the circumference, and which has a backrest installed on top of it, allowing the user to move freely. However, since the backrest is simply placed on the seat, it can shift position when the user leans on it (puts weight on it), making it unstable. In order to make it stable, it has to be somewhat heavy. If it is too heavy, it becomes difficult to move.

[0004] Another example is a bed mattress with a groove cut into the seat surface, into which the support rod of the backrest is inserted from above (Patent Document 1). This has the advantage that the backrest is unlikely to shift position even when the backrest is leaned on (weight is applied). However, the groove cutting process is troublesome. In addition, in order to make the backrest movable, the groove must be made long or cut into several places on the seat surface. In addition, since the groove is long horizontally, if the bed mattress is soft, the support rod will wobble and the backrest will become unstable. To stabilize the mattress, the bed mattress must be made hard, but if it is made hard, the comfort of sitting will be reduced. If the groove is made long, the unused part of the groove will be exposed on the seat surface, which will look bad or there is a risk of injury if a toe or finger is inserted into the exposed groove.

[0005] There is also a seating device as shown in Patent Document 2. This is a device in which insertion holes are drilled at several places on the surface of the base unit, and the insertion boss of the high block body can be inserted into the insertion holes to make a backrest, or the insertion boss of the low block body can be inserted into the insertion holes to make an armrest. In Patent Document 2, since the insertion boss can only be inserted into the places where there are insertion holes, in order to move the high block body or the low block body on the surface of the base unit, it is necessary to open more insertion holes than the number of insertion bosses, which makes the drilling process troublesome. In addition, the unused insertion holes are exposed on the surface of the base unit, which looks bad, and there is a risk of injury if a toe or finger is inserted into the exposed insertion holes.

[0006] [Patent Document 1] Patent Publication No. 2021-087773 [Patent Document 2] JP 2012-223484 A Summary of the Invention [Problem to be solved by the invention]

[0007] To provide a sofa accessory that can be attached (set) without opening an insertion groove or insertion hole on the seat surface (upper surface) of a sofa, can be moved (changed location) on the seat surface, and can be attached so as not to easily shift position, a sofa on which the sofa accessory can be attached, and a sofa with the sofa accessory attached. [Means for solving the problem]

[0008] The sofa of the present invention is a mattress, a mat, a sofa, a bed mattress, etc., the sofa accessories are a sofa backrest, an armrest, a pillow, a cushion, a plank-shaped table, a reading stand, a case, etc., and the sofa with accessories is a sofa on which the sofa accessories are installed.

[0009] The sofa furniture of the present invention is provided with support legs on the furniture body. The support legs have a clamping part and a locking part. The clamping part can be clamped between the sofa base and the seat cushion above it, and the locking part can be locked to a protrusion (base protrusion) protruding from the top surface of the base when the clamping part is clamped between the base and the seat cushion.

[0010] The sofa of the present invention is equipped with a seat cushion on a base, and there is a space (gap) between the base and the seat cushion in which the support leg of the sofa accessory can be sandwiched. The base has a base protrusion on its outer periphery, which is one step higher than the base top surface inside the base protrusion, and has a shape and height that allows the locking part of the support leg of the sofa accessory sandwiched in the gap to be locked.

[0011] The sofa with accessories of the present invention has the support legs of the sofa accessory sandwiched between the sofa base and the seat cushion on top of it, and the accessory body of the sofa accessory installed on the seat cushion. The support legs are engaged with the base protrusions to prevent them from accidentally coming off. The sofa accessory can be installed with the support legs along the periphery of the sofa and the engaging parts of the support legs engaged with the base protrusions, or the support legs can be installed straddling the corners of the sofa and the engaging parts of the support legs can be placed over the base protrusions and engaged. Effect of the Invention

[0012] The sofa furniture of the present invention has the following effects. (1) Because the support legs can be sandwiched between the sofa base and the seat cushion, there is no need to drill insertion grooves or holes on the top surface of the sofa. In addition, the position at which the support legs are sandwiched into the sofa can be changed and the sofa can be moved. (2) When the support leg is sandwiched between the sofa base and the seat cushion, the locking portion of the support leg locks onto the protrusion of the sofa, making the sofa accessory easier to stand on its own and less likely to shift out of position even when a load is applied.

[0013] The sofa of the present invention has the following effects. (1) Since the support legs of the sofa accessories can be inserted between the base and the seat cushion above it, the support legs can be inserted from the side of the sofa and clamped in place without the need for an insertion groove or hole on the top surface of the seat cushion. (2) Since the gap is located on the periphery between the base and the seat cushion, it is easy to change the insertion point of the support leg into the gap, and sofa furniture on the seat can be easily moved. (3) The support legs of the sofa accessory are sandwiched between the base and the seat cushion, and the locking parts of the support legs lock onto the protrusions of the sofa base, so the sofa accessory can stand on its own and is less likely to shift even when a load is applied. Therefore, there is no need to make the seat cushion harder to stabilize the sofa accessory, and the comfort of sitting on the seat cushion is not compromised.

[0014] The furnished sofa of the present invention has the following advantages. (1) The support legs of the sofa accessory are sandwiched between the sofa base and the seat cushion, so the sofa accessory is stable. Also, since the support legs are simply sandwiched between the sofa and the seat cushion, the sofa accessory can be easily moved since it can be inserted and removed from the side of the sofa. (2) The sofa accessories can be attached along the side of the sofa base or at the corners of the sofa, making them versatile. (3) The support legs of the sofa accessory are engaged with the base protrusions, making the sofa accessory stable. [Brief description of the drawings]

[0016] An embodiment of furniture for a sofa, a sofa, and a sofa with furniture of the present invention will be described with reference to Figs. 1 to 8(a) and (b).

[0017] (Embodiment of sofa furniture) The sofa furniture 1 can be attached (set) to a sofa 2 as shown in Fig. 1 and Fig. 8(a)(b). The sofa furniture 1 comes in various shapes and structures, but in any case, it has support legs 4 under the furniture main body 3 as shown in Fig. 1 and Fig. 8(a)(b).

[0018] [Main equipment] The furniture main body 3 in Fig. 1 to Fig. 7(a) is a general-purpose backrest made of cushioning material. The furniture main body 3 is generally triangular in side view, but the shape may be such that a rectangular front cushion 3b is provided on the front surface of a triangular back cushion 3a in side view, as shown in Fig. 3(a).

[0019] The fixture body 3 may be an armrest, a pillow, etc. In these cases, the shape, structure, material, etc. can be selected arbitrarily according to the purpose, but a cushioning material is suitable.

[0020] The flat fixture body 3 in Fig. 8(a) is a table. This fixture body 3 is a square plate, but the shape, structure, etc. may be other than that shown in the figure, and the material can be selected arbitrarily from wood, resin, elastic material, leather, synthetic resin, etc. according to the purpose.

[0021] Although not shown, the accessory main body 3 may be a case of various shapes and structures, such as a box or drawer, into which glasses, a remote control, a writing implement, etc. can be inserted and removed.

[0022] [Support legs] The support leg 4 is attached to the lower part of the fixture body 3 and protrudes forward of the fixture body 3. As shown in Fig. 3(a), this support leg 4 is equipped with a front bar 5a, a side bar 5b, and a vertical bar 5c, which are formed by bending a single bar 5 such as a round bar or a round pipe, and the rising part (curved part) 7 (Figs. 3(a) and (b)) of the vertical bar 5c is connected by a locking bar 8. The front bar 5a and the side bar 5b form a clamping part 6. When this clamping part 6 is clamped between the base 9 and the seat cushion 10 of the sofa 2, it is pressed down by the weight of a person sitting on the seat cushion 10, and the fixture body 3 becomes stable.

[0023] [Lock bar] As shown in Figures 4(a) and 8(b), the locking bar 8 is long enough to straddle the corner 11 of the sofa 2, and is equipped with locking parts 12 (Figure 6(b)) on both longitudinal ends. The locking parts 12 are raised and concave, and the height of the rise is such that they can cover protrusions (base protrusions) 13 formed on the periphery of the long side surface 2a and the short side surface 2b that sandwich the corner 11 of the sofa 2.

[0024] The intermediate portion of the locking bar 8 in the longitudinal direction may serve as the locking portion 12. The clamping portion 6 of the support leg 4 may be inserted into the long side surface 2a or the short side surface 2b of the base 9 and the seat cushion 10 from the outside of the sofa 2, as shown in Fig. 3(a) and Fig. 8(a), to clamp the same. In this case, the intermediate portion of the locking bar 8 in the longitudinal direction is disposed in the step portion 17 on the inner side of the base protrusion 13, as shown in Fig. 3(b), and is locked to the inner surface 13a of the base protrusion 13. In other words, the intermediate portion of the locking bar 8 in the longitudinal direction serves as the locking portion 12.

[0025] The support leg 4 has various shapes. The support leg 4 in FIG. 5 has three parallel bars 20 that are L-shaped in side view (L-shaped bars) protruding forward from the lower part of the fixture body 3. The support leg 4 has the forward protruding parts 20a of the three L-shaped bars 20 as the clamping part 6, the curved parts 7 of each L-shaped bar 20 are connected by a locking bar 8, and both ends of the locking bar 8 are raised to form the locking parts 12. The tips of the forward protruding parts 20a of the three L-shaped bars 20 can also be connected by a front bar (not shown) as in FIG. 3(a). In this case, the three front bars and the three forward protruding parts 20a form the clamping part 6.

[0026] The support leg 4 in Fig. 6(a) is two L-shaped bars attached to the fixture body 3. The support leg 4 in Fig. 6(b) has the same shape as the support leg 4 in Fig. 3(a).

[0027] The support leg 4 in FIG. 6(c) has basically the same shape as the support leg 4 in FIG. 6(a), but differs in that the two L-shaped bars 20 are made into flat plates.

[0028] The support leg 4 in FIG. 6(d) has basically the same shape as the support leg 4 in FIG. 6(b), but differs in that the two bars 5 and the front bar 5a are flat plates.

[0029] The support leg 4 in FIG. 7(a) has a bar 5 that is flat and L-shaped in a side view protruding from the lower part of the back of the fixture body 3, and a horizontally long auxiliary member 16 is provided at the tip of the forward protruding portion 21 of the bar 5. The forward protruding portion 21 and the auxiliary member 16 form the clamping portion 6, and the locking protrusion 18 is fixed to the back surface of the forward protruding portion 21. The locking protrusion 18 is a round bar that is longer than the width of the forward protruding portion 21 and protrudes outward from both ends of the forward protruding portion 21 in the width direction. When the clamping portion 6 is inserted between the base 9 and the seat cushion 10 from the side surface 2a on the long side of the sofa 2 as shown in FIG. 1, the locking protrusion 18 becomes the locking portion 12 that locks with the base protrusion 13, similar to the longitudinal center of the locking bar 8 in FIG. 3(a). The bar 5 and the locking protrusion 18 may be square bars, round pipes, square pipes, or other shapes.

[0030] Even when the fixture body 3 is an armrest, a pillow, a case, etc., the support legs 4 can be the same as those in the cases of Figures 3(a) and (b). The height of the support legs 4 can be designed as desired depending on the application.

[0031] The support leg 4 in Fig. 8(a) is attached to the bottom surface of the fixture body (table) 3, and as shown in Fig. 8(b), a single bar 5 is bent to form a front bar 5a, a side bar 5b, a vertical bar 5c, and an attachment bar 19, and the curved parts 7 of the two vertical bars 5c are connected by a locking bar 8, and concave locking parts 12 are provided on both ends of the locking bar 8. This support leg 4 has the attachment bar 19 attached to the bottom surface of the fixture body 3, the vertical bar 5c protruding downward, and the side bar 5b and front bar 5a protruding forward form the clamping part 6.

[0032] (Sofa embodiment) The sofa 2 of the present invention is a mattress, mat, bed mattress, sofa, chair, etc., on which a person can sit, and is made of cushioning material. The sofa 2 in FIG. 1 has a seat cushion 10 placed on a base 9. The base 9 has a base protrusion 13 (FIGS. 3(a)(b)) on the entire circumference (including almost the entire circumference) of its outer periphery. The base protrusion 13 is one step higher than the base upper surface 14 on the inside, and there is a step portion 17 between the base protrusion 13 and the base upper surface 14. A space (gap) S is provided on the entire outer periphery between the base 9 and the seat cushion 10, into which the clamping portion 6 of the support leg 4 of the sofa accessory 1 can be inserted. The clamping portion 6 can be inserted from any point in the gap S on the periphery. The base 9 and seat cushion 10 in FIG. 1 are rectangular, but they may be circular or any other shape.

[0033] 3(b), 4(b), and 7(b) are bank-shaped convex stripes with a somewhat horizontally elongated cross-sectional shape, and have a height (e.g., several mm to several tens of mm) and shape that allows them to cover the concave locking portion 12 of the locking bar 8 sandwiched between the base 9 and the seat cushion 10. The shape and height can be designed as desired, and a shape and height that allow the locking portion 12 to be stably placed over the base protrusion 13 are desirable.

[0034] (Embodiment of sofa with accessories) The sofa with furniture of the present invention is a sofa 2 of the present invention equipped with sofa furniture 1 of the present invention, as shown in Figures 1, 2, and 8(a) and (b). In Figures 1 and 2, sofa furniture (backrest) 1 is attached to both the side surface 2a of the long side of one sofa 2 and to the top of a corner 11. In Figure 8(a), two sofa furniture pieces (backrest and table) 1 are attached to the side surface 2a of the long side of one sofa 2. In Figure 8(b), sofa furniture (table) 1 is attached to the corner of one sofa 2.

[0035] The sofa furniture 1 attached to the long side 2a has the clamping portion 6 of the support leg 4 inserted between the base 9 on the long side 2a of the sofa 2 and the seat cushion 10 above it, so that the clamping portion 6 is clamped between the base 9 and the seat cushion 10. In this case, the locking bar 8 of the support leg 4 is arranged at the step portion 17 inside the base protrusion 13 as shown in Figures 3(a) and (b), so that the middle portion (locking portion) 12 of the locking bar 8 can be locked to the inner surface 13a of the base protrusion 13. With this structure, the sofa furniture 1 is less likely to shift outward even when leaning against it.

[0036] The sofa furniture 1 mounted on the corner 11 has the clamping portion 6 of the support leg 4 inserted from the long side 2a and short side 2b in Fig. 1 that sandwich the corner 11 of the sofa 2. In this case, the locking bar 8 of the support leg 4 is placed across the corner 11 as shown in Figs. 4(a)(b) and 8(b), and the locking portion 12 of the locking bar 8 is fitted over and locked onto the base protrusion 13 of the base 9. This makes it difficult for the sofa furniture 1 to shift outward even when leaning against it.

[0037] As shown in Fig. 1, whether the sofa furniture 1 is attached to the long side surface 2a of the sofa 2 or to the corner 11 of the sofa 2, the support leg 4 can be pulled out from between the base 9 and the seat cushion 10 of the sofa 2 by releasing the engagement between the locking part (the longitudinal center part of the locking bar 8) 12 of the sofa furniture 1 and the base protrusion 13. By inserting the clamping part 6 of the support leg 4 of the pulled-out sofa furniture 1 into another position between the base 9 and the seat cushion 10 of the sofa 2, the sofa furniture 1 can be moved to another position on the sofa 2. [Industrial Applicability]

[0038] The sofa accessory 1 in the present invention may be something other than a backrest, armrest, pillow, or table. The shape, structure, material, etc. of the accessory body 3 and the support legs 4 of the sofa accessory 1 can be modified in design within a range that can solve the problems of the present invention. The shape, size, etc. of the sofa 2 in the present invention can also be modified in design within a range that can solve the problems of the present invention, for example, the sofa 2 may or may not have support legs to be placed on the floor. The sofa 2 can be square, circular, elliptical, or any other shape in plan view. In the case of the rectangular sofa in FIG. 1, the side faces are the side face 2a on the long side and the side face 2b on the short side, but in the case of a square, the sides 2a and 2b are sides of the same length. In addition, in the case of the rectangular sofa in FIG. 1, there is a corner 11, but in the case of a sofa that is circular or elliptical in plan view, the part sandwiched between the two sides into which the support legs can be inserted corresponds to the corner 11 in FIG. 1.
