Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] 〈Overall Configuration〉 First, the overall configuration of one embodiment of the sofa of the present invention will be described.

[0013] FIG. 1 is a front view of one embodiment of the sofa of the present invention. FIG. 2 is a top view of the sofa 1 shown in FIG. 1.

[0014] As shown in FIGS. 1 and 2, the present embodiment is a sofa 1 having a seat surface portion 10, a backrest portion 20, an armrest portion 30, a table 40, and a holding member 50.

[0015] The seat surface portion 10 is located at the buttocks and even part of the lower thigh when a person sits on the sofa 1, has a certain height, and is configured to face upward. The seat surface portion 10 may have a cushioning property by incorporating urethane or a spring inside. In the present embodiment, a configuration in which three people can sit side by side is exemplified, but the number of people who can sit is not limited to three. Also, when a plurality of people can sit, each part corresponding to the person sitting may independently have a cushioning property.

[0016] The backrest portion 20 supports the back from the rear by contacting the back when a person sits on the sofa 1, is connected to the rear end of the seat surface portion 10, and stands upward in a state slightly inclined rearward therefrom. Further, the backrest portion 20 may be of a so-called high-back type that also supports the back of the head of a person sitting on the sofa 1. The backrest portion 20 may have a cushioning property by incorporating urethane or a spring inside. In the present embodiment, a configuration in which three people can sit side by side is exemplified, but the number of people who can sit is not limited to three. Also, when a plurality of people can sit, each part corresponding to the person sitting may independently have a cushioning property. Furthermore, each of the seat surface portion 10 and the backrest portion 20 may be configured to be separable between the parts corresponding to the person sitting.

[0017] The armrest portions 30 are respectively connected and provided at both ends of the seating surface portion 10. In the present embodiment, since the sofa 1 is such that three people can sit side by side, the armrest portions 30 include one for placing the elbow of the left arm of a person sitting at the left end of the seating surface portion 10 and one for placing the elbow of the right arm of a person sitting at the right end of the seating surface portion 10. The armrest portion 30 has a covering cover 30a and a base portion 30b. The base portion 30b is respectively connected and erected at both ends of the seating surface portion 10. The covering cover 30a constitutes an example of the covering portion in the present invention. The covering cover 30a is provided so as to cover the upper surface of the base portion 30b and constitutes the portion for placing the elbow of a person sitting on the sofa 1. The covering cover 30a may have a cushioning property by incorporating urethane or the like inside.

[0018] The table 40 is configured in a rectangular plate shape. When not in use, the table 40 is housed in the base portion 30b of the armrest portion 30 in an erected posture. When in use, the table 40 is taken out from the armrest portion 30 and assumes a horizontal posture. In FIGS. 1 and 2, a state is shown in which the table 40 is housed in the armrest portion 30 on the right side in the drawing and the table 40 is taken out from the armrest portion 30 on the left side in the drawing. Note that the shape of the table 40 is not limited to a rectangle, and may be a square, a circle, or a shape with rounded corners of a rectangular shape such as a rectangle, as long as the table 40 can be housed in the base portion 30b.

[0019] The holding member 50 is in a bent cylindrical shape, and one end is attached to the table 40 to hold the table 40. Its detailed configuration will be described later.

[0020] <Internal Configuration of the Armrest Portion 30> Next, the internal configuration of the armrest portion 30 shown in FIG. 1 will be described.

[0021] FIG. 3 is a view showing the configuration inside the base portion 30b of the armrest portion 30 shown in FIG. 1, and is a view of the armrest portion 30 on the left side in FIG. 1 seen obliquely from the rear. Note that the armrest portion 30 on the right side in FIG. 1 also has a shape that is symmetric with this about the left and right.

[0022] As shown in FIG. 3, the armrest portion 30 shown in FIG. 1 has a housing portion 31 with an open upper surface inside the base portion 30b. The end portions on the opening side of the base portion 30b are opening edges 32a and 32b with different heights from each other. The opening edge 32a constitutes the upper ends of the side surface of the base portion 30b opposite to the seat surface portion 10, and the front and rear side surfaces of the sofa 1. The opening edge 32b is lower than the opening edge 32a, and constitutes the upper ends of the side surface on the seat surface portion 10 side of the base portion 30b, and the front and rear side surfaces of the sofa 1. Note that the front and rear side surfaces of the base portion 30b of the sofa 1 are configured such that the opening edge 32b exists inside the opening edge 32a (see FIG. 6). A recess 34 that is recessed downward is provided in a part of the portion of the opening edge 32b that constitutes the upper end of the side surface on the seat surface portion 10 side by cutting a part thereof. In addition, a columnar support 35 is provided in the housing portion 31. One end of the support 35 is fixed to the bottom surface of the housing portion 31 and extends upward therefrom. A plate-shaped fixing member 36 is attached to the portion of the opening edge 32b that constitutes the upper end of the front side surface of the sofa 1. The fixing member 36 has a shape protruding from the opening edge 32b to the inside of the housing portion 31, and the other end of the support 35 is fixed to the fixing member 36. Thereby, the support 35 is provided extending in the vertical direction in the region on the front side of the sofa 1 in the housing portion 31.

[0023] With respect to the base portion 30b configured as described above, a covering cover 30a is attached to the portion of the opening edge 32a that constitutes the upper end of the side surface opposite to the seat surface portion 10. By rotating the covering cover 30a about the opening edge 32a, the housing portion 31 can be covered in an openable and closable manner.

[0024] <Configuration of the holding member 50> Next, the configuration of the holding member 50 shown in FIG. 1 will be described.

[0025] FIG. 4 is a diagram showing the configuration of the holding member 50 shown in FIG. 1, and is a view seen from the front of the sofa 1 when the table 40 is taken out from the armrest portion 30 and assumes a horizontal posture. FIG. 5 is a diagram for explaining the relationship between the holding member 50 and the table 40 shown in FIG. 4, and shows the configuration of the surface of the table 40 to which the holding member 50 is attached.

[0026] As shown in FIG. 4, the holding member 50 shown in FIG. 1 includes a slide cylinder 51, a connection pipe 52, and rotation fixing members 53 and 54.

[0027] The slide cylinder 51 is attached to the support column 35 by enclosing the support column 35 inside the cylinder. The slide cylinder 51 is attached to the support column 35 so as to be movable in the vertical direction (direction A in FIG. 4) with respect to the support column 35 and rotatable in the horizontal direction (direction B in FIG. 4) around the support column 35.

[0028] One end of the connection pipe 52 is attached to the slide cylinder 51, the other end is attached to the rotation fixing member 53, and it is composed of three continuous support portions 52a to 52c. The support portion 52a is an example of the first support portion in the present invention. One end of the support portion 52a is attached to the slide cylinder 51 and extends in a direction away from the support column 35. One end of the support portion 52b is continuous with the end of the support portion 52a opposite to the slide cylinder 51, and extends at a predetermined angle in a direction away from the support column 35 with respect to the direction in which the support column 35 extends. One end of the support portion 52c is continuous with the end of the support portion 52b opposite to the support portion 52a, and extends parallel to the support portion 52a toward the support column 35 side. The end of the support portion 52c opposite to the support portion 52b is attached to the rotation fixing member 53. In this way, the connection pipe 52 has a cylindrical shape with two bent regions between one end and the other end. Note that an example of the second support portion in the present invention is constituted by the support portion 52b and the support portion 52c. Since the connection pipe 52 is constituted by the three support portions 52a to 52c as described above, when the table 40 is taken out from the armrest portion 30 and assumes a horizontal posture, the rotation fixing member 53 is positioned on the seat surface portion 10 side by X1 from the support column 35.

[0029] As shown in FIGS. 4 and 5, the rotation fixing member 53 has a columnar shape and has an insertion hole (not shown) on the side surface into which the support portion 52c is inserted. When the support portion 52c is inserted into the insertion hole of the rotation fixing member 53, the rotation fixing member 53 is rotatably attached to the support portion 52c about the axis of the support portion 52c in the direction in which the main surface of the table 40 tilts (direction C in the figure). A unlocking tool 55 is provided on the side surface of the rotation fixing member 53 so as to protrude from the side surface of the rotation fixing member 53. The unlocking tool 55 is for releasing the rotation lock of the support portion 52c with respect to the rotation fixing member 53, and is biased toward the center of the rotation fixing member 53 by a spring (not shown) or the like.

[0030] A rotation fixing member 54 is attached to the rotation fixing member 53. The rotation fixing member 54 has a frustum shape and is attached to the rotation fixing member 53 such that the top surface faces the bottom surface of the rotation fixing member 53 as shown in FIGS. 4 and 5. At this time, the shape of the bottom surface of the rotation fixing member 53 and the shape of the top surface of the rotation fixing member 54 may be configured to be the same. Further, the table 40 is attached to the bottom surface of the rotation fixing member 54. The rotation fixing member 54 is attached to the surface of the table 40 on the side opposite to the use surface of the table 40 (hereinafter referred to as the back surface) by screws (not shown) or the like. The attachment position of the rotation fixing member 54 to the table 40 may be in the central portion in the short side direction of the rectangular table 40 and in the region along one short side in the long side direction. A rotation axis (not shown) extending from the bottom surface of the rotation fixing member 53 or the top surface of the rotation fixing member 54 is provided on one of these rotation fixing members 53 and 54, and a cylindrical groove into which this rotation axis enters is provided on the other of the rotation fixing members 53 and 54. Thereby, the rotation fixing member 54 can rotate with respect to the rotation fixing member 53 in the in-plane direction of the table 40 (direction D in FIG. 5). Note that an example of the holding portion in the present invention is configured by the rotation fixing member 53 and the rotation fixing member 54.

[0031] With such a configuration, one end of the connection pipe 52 is attached to the support column 35 via the slide cylinder 51, and the other end is attached to the back surface of the table 40 via the rotation fixing members 53 and 54. The table 40 is rotatable in the direction in which the main surface is inclined with respect to the connection pipe 52 (direction C in FIG. 5), and is also rotatable in the direction parallel to the main surface with respect to the rotation fixing member 53 (direction D in FIG. 5).

[0032] A groove portion 41 recessed from the back surface is provided on the table 40 along one of the end edges of the surface to which the rotation fixing member 54 is attached.

[0033] 〈Storage form of the table 40〉 Next, the state in which the table 40 is stored in the armrest portion 30 will be described.

[0034] FIG. 6 is a view of the state in which the table 40 is stored in the armrest portion 30 as seen from above, and FIG. 7 is a perspective view of the state in which the table 40 is stored in the armrest portion 30 as seen from the side.

[0035] In the sofa 1 shown in FIG. 1, the table 40 is stored in the armrest portion 30 as described above. The table 40 is stored in the storage portion 31 of the armrest portion 30 in an upright posture as shown in FIGS. 6 and 7.

[0036] At this time, the slide cylinder 51 is located at the lowermost position of the support column 35. This can be achieved by moving the slide cylinder 51 to the lowermost position along the support column 35 because the slide cylinder 51 is attached to the support column 35 so as to be movable in the vertical direction as described above.

[0037] Also, the connection pipe 52 is in a state of following the table 40. This can be achieved by rotating the slide cylinder 51 around the support column 35 so that the connection pipe 52 follows the table 40 because one end of the connection pipe 52 is attached to the slide cylinder 51 and the slide cylinder 51 is attached to the support column 35 so as to be rotatable in the horizontal direction as described above.

[0038] Further, the rectangular table 40 is oriented such that its long side extends horizontally. As described above, since the rotation fixing member 54 attached to the back surface of the table 40 can rotate in a direction parallel to the main surface of the table 40 with respect to the rotation fixing member 53 attached to the end of the connection pipe 52 on the side opposite to the slide cylinder 51, it can be realized by rotating the table 40 so that its long side extends horizontally. In this way, by setting the long side of the table 40 to extend horizontally, even when the depth of the storage portion 31 is shallow, the table 40 can be configured to be accommodated in the storage portion 31 without shortening the length of the long side of the table 40.

[0039] 〈Usage method of the table 40〉 Next, the procedure for taking out and using the table 40 accommodated in the armrest portion 30 as described above will be explained.

[0040] FIGS. 8 to 14 are diagrams for explaining the procedure for taking out and using the table 40 accommodated in the armrest portion 30, and are perspective views of the armrest portion 30 as viewed from the front side of the seat surface portion 10.

[0041] When taking out and using the table 40 accommodated in the armrest portion 30, first, as shown in FIG. 8, open the covering cover 30a to make it possible to take out the table 40 from the storage portion 31. As described above, since the covering cover 30a is rotatably attached to the base portion 30b about the opening edge 32a, the covering cover 30a can be rotated about the opening edge 32a to make it possible to take out the table 40 from the storage portion 31.

[0042] Next, as shown in FIG. 9, the table 40 housed in the housing portion 31 is vertically pulled out upward (in the E direction in FIG. 9). As described above, the table 40 is attached to the connection pipe 52 via the rotation fixing members 53 and 54. Further, the connection pipe 52 is attached to the support column 35 via the slide cylinder 51 so as to be movable in the vertical direction. Therefore, by vertically moving the table 40 upward along the support column 35 together with the connection pipe 52, the table 40 housed in the housing portion 31 can be vertically pulled out upward. At this time, as described above, the table 40 is provided with a groove portion 41 along one of the end sides of the surface to which the rotation fixing member 54 is attached. Therefore, if the table 40 is housed in the housing portion 31 such that the end side along which the groove portion 41 extends becomes the upper end portion in the state where the table 40 is housed in the housing portion 31, the table 40 housed in the housing portion 31 can be easily pulled out by hooking a finger on the groove portion 41.

[0043] Next, as shown in FIG. 10, the table 40 pulled out upward from the housing portion 31 is rotated 90° in a direction parallel to the main surface (in the F direction in FIG. 10). As described above, the rotation fixing member 54 is attached to the back surface of the table 40. Further, the rotation fixing member 53 is attached to one end of the connection pipe 52. And the rotation fixing member 54 is attached to the rotation fixing member 53 so as to be rotatable in a direction parallel to the main surface of the table 40. Therefore, the table 40 pulled out upward from the housing portion 31 can be rotated 90° in a direction parallel to the main surface. As a result, the rectangular table 40 is in a state where the long side faces in the vertical direction.

[0044] Next, as shown in FIG. 11, the table 40 is rotated together with the connection pipe 52 in the direction in which the use surface of the table 40 (hereinafter referred to as the surface) of the main surface of the table 40 faces the rear of the sofa 1 (direction G in FIG. 11). As described above, the table 40 is attached to the connection pipe 52 via the rotation fixing members 53 and 54. One end of the connection pipe 52 is attached to the slide cylinder 51, and the slide cylinder 51 is attached to be rotatable in the horizontal direction around the support column 35. Therefore, the table 40 can be rotated together with the connection pipe 52 around the support column 35 so that the surface of the table 40 faces the rear of the sofa 1.

[0045] In this way, by rotating the rectangular table 40 with the long side of the table 40 facing in the vertical direction, even when the length of the long side of the table 40 is long, it is possible to avoid the rotating table 40 hitting a person when a person is sitting on the sofa 1.

[0046] Then, the support portion 52a of the connection pipe 52 will be located on the portion that constitutes the upper end of the side surface on the seat surface 10 side of the opening edge 32b of the base portion 30b. As described above, a recess 34 that is recessed downward is provided in the portion that constitutes the upper end of the side surface on the seat surface 10 side of the opening edge 32b. Therefore, by pushing down the connection pipe 52 together with the table 40 in the downward direction (direction H in FIG. 11), the support portion 52a of the connection pipe 52 can be fitted into the recess 34.

[0047] Next, as shown in FIG. 12, rotate in the direction in which the main surface of the table 40 tilts (direction I in FIG. 12) so that the table 40 is changed from the standing posture to the horizontal posture. As described above, the table 40 is attached to the rotation fixing member 53 via the rotation fixing member 54. Further, the rotation fixing member 53 is rotatably attached to the support portion 52c of the connection pipe 52 about the axis of the support portion 52c in the direction in which the main surface of the table 40 tilts. Therefore, it is possible to rotate in the direction in which the main surface of the table 40 tilts and change the table 40 from the standing posture to the horizontal posture. Then, when the table 40 is changed from the standing posture to the horizontal posture, the rotation of the support portion 52c with respect to the rotation fixing member 53 is locked.

[0048] Next, as shown in FIG. 13, rotate the table 40, which has changed from the standing posture to the horizontal posture, by 90° in the direction parallel to the main surface (direction J in FIG. 13). As described above, the rotation fixing member 54 is attached to the back surface of the table 40. Further, the rotation fixing member 53 is attached to one end of the connection pipe 52. And the rotation fixing member 54 is rotatably attached to the rotation fixing member 53 in the direction parallel to the main surface of the table 40. Therefore, it is possible to rotate the table 40, which has changed from the standing posture to the horizontal posture, by 90° in the direction parallel to the main surface. As a result, the long side of the rectangular table 40 extends in the left - right direction of the person sitting on the sofa 1, and the table 40 can be widely used in the left - right direction.

[0049] Thereafter, as shown in FIG. 14, rotate the covering cover 30a to close the opening of the accommodating portion 31 with the covering cover 30a and return the armrest portion 30 to its original state. As described above, since the covering cover 30a is rotatably attached to the base portion 30b about the opening edge 32a, it is possible to rotate the covering cover 30a about the opening edge 32a to close the opening of the accommodating portion 31 with the covering cover 30a.

[0050] As a result, the table 40 is taken out of the accommodating portion 31 and assumes a horizontal posture for use, enabling objects to be placed on the table 40 or operations such as writing to be performed on the table 40. At this time, the support portion 52a of the connection pipe 52 that holds the table 40 is in contact with the opening edge 32b of the armrest portion 30. Therefore, the table 40 is supported not only by the support column 35 via the connection pipe 52 but also in a supported state at the opening edge 32b via the support portion 52a. Thereby, the load-bearing strength of the table 40 can be improved. Further, a recessed portion 34 that is recessed downward is provided at the opening edge 32b of the armrest portion 30, and in the state of using the table 40, the support portion 52a of the connection pipe 52 is fitted into the recessed portion 34. Therefore, the load-bearing strength of the table 40 can be improved, and it is possible to avoid the connection pipe 52 rotating with respect to the support column 35 in the state of using the table 40.

[0051] Also, since the support portion 52a of the connection pipe 52 is fitted into the recessed portion 34, as described above, when the table 40 is taken out of the accommodating portion 31 of the armrest portion 30 for use and the covering cover 30a is rotated to return the armrest portion 30 to its original state, the covering cover 30a will not abut against the connection pipe 52 and prevent the armrest portion 30 from returning to its original state.

[0052] After that, when accommodating the table 40 in the armrest portion 30, the above-described operations may be performed in reverse, but the table 40 is locked in a horizontal posture. Therefore, when returning the table 40 from a horizontal posture to an upright posture, the lock of the rotation of the support portion 52c with respect to the rotation fixing member 53 is released by pulling the unlocking tool 55 in a direction away from the side surface of the rotation fixing member 53, and in this state, the table 40 is returned from a horizontal posture to an upright posture. As described above, since the unlocking tool 55 is biased toward the center of the rotation fixing member 53 by a spring (not shown) or the like, if the hand is released from the unlocking tool 55 after returning the table 40 from a horizontal posture to an upright posture, then when the table 40 subsequently assumes a horizontal posture, the rotation of the support portion 52c with respect to the rotation fixing member 53 returns to a locked state.

[0053] <Position in the state of use of Table 40> Next, the positional relationship with the armrest portion 30 in the state of use of the table 40 will be described.

[0054] FIGS. 15 and 16 are diagrams for explaining the positional relationship with the armrest portion 30 in the state of use of the table 40. FIG. 15 is a side view of the sofa 1, and FIG. 16 is a front view of the sofa 1.

[0055] As described above, in the present embodiment, in a configuration in which the table 40 can be accommodated in the accommodating portion 31 of the armrest portion 30, a support column 35 extending in the vertical direction is provided in the accommodating portion 31. Further, a holding member 50 having one end attached to the support column 35 and the other end attached to the back surface of the table 40 is attached to the support column 35 so as to be movable in the vertical direction and rotatable in the horizontal direction, and holds the table 40 so as to be rotatable from an upright posture to a horizontal posture.

[0056] Thereby, the table 40 accommodated in the accommodating portion 31 can be pulled out upward in the vertical direction, and the holding member 50 and the table 40 can be rotated in a direction in which the main surface of the table 40 is inclined on the spot. And since the support column 35 for pulling out the table 40 upward together with the holding member 50 is provided in the accommodating portion 31, as shown in FIG. 15, in the state of use of the table 40, the rotation fixing members 53 and 54 that hold the table 40 using the connection pipe 52 are located at a position Y1 lower rearward from the position L at the tip of the armrest portion 30.

[0057] Also, as described above, when the table 40 is taken out from the armrest portion 30 and becomes a horizontal posture, the connection pipe 52 is configured such that the rotation fixing member 53 is located on the seat surface portion 10 side by X1 (see FIG. 4) from the support column 35. Thereby, as shown in FIG. 16, in the state of use in which the table 40 is pulled out from the accommodating portion 31 and becomes a horizontal posture, the rotation fixing members 53 and 54 are located on the seat surface portion 10 side by X1 from the central position M in the adjacent direction to the seat surface portion 10 of the armrest portion 30.

[0058] This eliminates the possibility that a person sitting on the sofa 1 will feel that the table 40 is too far from their body. Also, since the table 40 is attached to the support column 35 via the holding member 50, the height of the table 40 can be made higher than the height of the armrest portion 30. Thus, the sofa 1 in the present embodiment is comfortable in terms of the height of the table 40 accommodated in the armrest portion 30 and the distance from the body in the state of use of the table 40.

[0059] Further, the holding member 50 holds the table 40 so as to be rotatable also in a direction parallel to the main surface. Thereby, even when the depth of the accommodating portion 31 is shallow, the table 40 can be accommodated in the accommodating portion 31 without shortening the length of the long side of the table 40. Even when the table 40 is accommodated in the accommodating portion 31 with the long side of the table 40 extending in the horizontal direction, when the table 40 is rotated in the direction in which the surface of the table 40 faces the rear of the sofa 1 as shown in FIG. 11, it is possible to avoid the rotated table 40 hitting a person when a person is sitting on the sofa 1.

[0060] (Other embodiments) In the above-described embodiment, as shown in FIGS. 10 and 13, the table 40 pulled out from the accommodating portion 31 is rotated twice in a direction parallel to the main surface. As described above, by rotating the table 40 with the long side of the rectangular table 40 facing in the vertical direction, even when the length of the long side of the table 40 is long, it is possible to avoid the rotated table 40 hitting a person when a person is sitting on the sofa 1. Therefore, if there is no risk of the table 40 hitting a person when the table 40 is rotated in the direction in which the surface of the table 40 faces the rear of the sofa 1 when a person is sitting on the sofa 1, for example, when the length of the long side of the table 40 is not long or the table 40 is square, there is no need to deliberately rotate the table 40 pulled out from the accommodating portion 31 in a direction parallel to the main surface.

[0061] In that case, as shown in FIG. 9, after vertically pulling out the table 40 housed in the housing portion 31 upward, as shown in FIG. 11, the table 40 is rotated in a direction in which the main surface of the table 40 faces the rear of the sofa 1, and then the table 40 may be placed in a horizontal posture. That is, in such a case, since the table 40 pulled out from the housing portion 31 is not rotated in a direction parallel to the main surface, the rotation fixing member 53 may be directly attached to the back surface of the table 40 without providing the rotation fixing member 54.
