[Technical field]

[0001] The present invention relates to a chair. [Background technology]

[0002] Conventionally, there are known chairs that have panels on the sides or rear of a chair body having a seat and a backrest, and that can separate the space in which a user sits from the surroundings (see, for example, Patent Documents 1 to 3). In such chairs, when the panel is fixed to the chair body, it is fixed to the frame that supports the seat or the backrest. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-064292 A [Patent Document 2] JP 2017-086384 A [Patent Document 3] JP 2019-058530 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the point at which the panel body is fixed to the chair body is determined by the shape of the frame supporting the seat and the backrest, there is a risk that the panel body cannot be fixed to the chair body in a stable manner.

[0005] SUMMARY OF THE PRESENT EMBODIMENTS Accordingly, an object of the present invention is to provide a chair in which a panel body (side panel body) can be installed in a stable state. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a chair comprising a seat having a seat surface, a frame structure supported by a floor and installed on the side of the seat surface to support the seat surface, and a side panel body connected to the frame structure and disposed on the side of the seat surface, the frame structure having a first horizontal rod extending in the depth direction above the seat surface and a second horizontal rod extending in the depth direction below the first horizontal rod, the side panel body being fixed to each of the first and second horizontal rods and having an upper edge located above the first horizontal rod. do.

[0007] In the present invention, the first and second horizontal rods of the frame structure each extend in the depth direction and are disposed at different heights. This allows the side panel bodies to be connected to the frame structure at different heights. Also, the side panel bodies can be connected to the frame structure at different heights at multiple locations spaced apart in the depth direction or in a predetermined range extending in the depth direction. This allows the side panel bodies to be installed in a stable state. In the present invention, the upper edge of the side panel body is located above the first horizontal rod, and the height dimension is greater than the dimension from the first horizontal rod to the second horizontal rod. By fixing the side panel body to the first and second horizontal rods as described above, even a large side panel body can be installed in a stable state.

[0008] In order to achieve the above objectives, The chair according to the present invention comprises: a seat having a seat surface, a frame structure supported by a floor and installed on the side of the seat surface to support the seat surface, and a side panel body connected to the frame structure and disposed on the side of the seat surface, the frame structure having a first horizontal rod extending in the depth direction above the seat surface and a second horizontal rod extending in the depth direction below the first horizontal rod, the side panel body being connected to each of the first horizontal rod and the second horizontal rod, and an upper edge portion being located above the first horizontal rod, A panel lower edge support member is fixed to the second horizontal rod and supports the lower edge of the side panel body. The panel lower edge support member has a mounting portion fixed to the second horizontal rod and extending laterally from the second horizontal rod, and a pressing portion extending upward from a position on the mounting portion away from the second horizontal rod, and the lower edge of the side panel body is fitted between the second horizontal rod and the pressing portion and placed on the mounting portion.

[0009] With this configuration, the side panel body can be stably connected to the second horizontal rod. Also, the side panel body can be easily connected to the second horizontal rod and can be easily removed from the second horizontal rod.

[0010] In order to achieve the above objectives, Chair according to the present invention a seat having a seat surface, a frame structure supported by a floor and installed on the side of the seat surface to support the seat surface, and a side panel body connected to the frame structure and disposed on the side of the seat surface, the frame structure having a first horizontal rod extending in the depth direction above the seat surface and a second horizontal rod extending in the depth direction below the first horizontal rod, the side panel body being connected to each of the first horizontal rod and the second horizontal rod, and an upper edge portion being located above the first horizontal rod, A panel support member for supporting the side panel body is fixed to at least one of the first and second horizontal bars, and the panel support member has a panel pressing portion for pressing the side panel body from the side toward the horizontal bar, and the position at which the panel support member is attached to the horizontal bar can be selected from a first position where the panel pressing portion is arranged at a distance to the side of the horizontal bar and can press the side panel body, and a second position where the panel pressing portion is in contact with the horizontal bar. be.

[0011] With this configuration, when the side panel body is installed on the chair, the panel support member is fixed to the horizontal rod at the first position, so that the panel pressing part presses the side panel body to support it on the horizontal rod. Also, when the panel support member is fixed to the horizontal rod at the second position, the panel pressing part can be prevented from protruding from the horizontal rod. Therefore, when the side panel body is not installed on the chair (when the side panel body is removed from the chair), the panel support member is fixed to the horizontal rod at the second position, so that even if the panel support member remains attached to the horizontal rod, there is no sense of incongruity in use or design. Therefore, when the side panel body is not installed on the chair, there is no need to store the panel support member separately, and management is easy. Also, when the panel support member is fixed to the horizontal rod at the second position, the panel pressing part covers the holes and metal fittings for fixing the panel support member to the horizontal rod, so that the appearance of the chair can be improved even when the side panel body is not installed on the chair.

[0012] In order to achieve the above objectives, Chair according to the present invention a seat having a seat surface, a frame structure supported by a floor and installed on the side of the seat surface to support the seat surface, and a side panel body connected to the frame structure and disposed on the side of the seat surface, the frame structure having a first horizontal rod extending in the depth direction above the seat surface and a second horizontal rod extending in the depth direction below the first horizontal rod, the side panel body being connected to each of the first horizontal rod and the second horizontal rod, and an upper edge portion being located above the first horizontal rod, The seat has a rear panel body disposed behind the seat portion, and the rear panel body is supported by the side panel bodies. There are.

[0013] With this configuration, if the side panel body is connected to the frame structure, the rear panel body can be installed behind the seat without being connected to the backrest, etc. Also, by removing the side panel body from the frame structure, the rear panel body can also be removed.

A second support member 8 (panel lower edge support member, see Figs. 1, 3 and 5) for fixing the side panel body 5 is fixed to the second horizontal rod 42. The second support member 8 is a long member extending in the front-rear direction and supports the side panel body 5 over a predetermined range in the front-rear direction. Details of the first support member 7 and the second support member 8 will be described later.

[0027] Each of the pair of side panel bodies 5, 5 is formed in a flat plate shape with a trapezoidal plate surface. As described above, one of the pair of side panel bodies 5, 5 is symmetrical to the other. The side panel body 5 is arranged so that the plate surface is a vertical plane facing the left-right direction. When the side panel body 5 is arranged in this manner, the upper edge portion 5a and the lower edge portion 5b extend in the front-rear direction, the front edge portion 5c extends in the up-down direction, and the rear edge portion 5d extends in a direction that gradually slopes backward toward the upper side. The inclination of the rear edge portion 5d is approximately the same as the inclination of the backrest portion 3 and the second vertical rod 45.

[0028] The side panel body 5 is disposed on the side (outside in the left-right direction) of the frame structure 4. The side panel body 5 has a lower edge 5b located at the height of the second horizontal rod 42, an upper edge 5a located above the first horizontal rod 41, a front edge 5c located forward of the first vertical rod 44, and a rear edge 5d located on the side (outside in the left-right direction) of the second vertical rod 45. The side panel body 5 is disposed above the floor surface 12 with a gap therebetween. The upper side of the side panel body 5 is disposed above the frame structure 4.

[0029] A first support member insertion hole 51 is formed in the side panel body 5, through which the first support member 7 is inserted. A plurality of first support member insertion holes 51 are formed at positions on the side panel body 5 that are connected to the first horizontal rod 41, spaced apart in the front-rear direction. In this embodiment, two first support member insertion holes 51 are formed in the side panel body 5. The first support member insertion hole 51 is formed at a position that overlaps with the first support member insertion recess 411 of the first horizontal rod 41 in the left-right direction.

[0030] The rear panel body 6 is formed in a flat plate shape with a rectangular plate surface. The rear panel body 6 has a plate surface facing approximately in the front-rear direction, and gradually inclines backward from the lower side to the upper side along the backrest portion 3 and the second vertical rod 45. The upper edge portion 6a of the rear panel body 6 is disposed at the same height as the upper edge portion 5a of the side panel body 5. The lower edge portion 6b of the rear panel body 6 is disposed at the same height as the lower edge portion 5b of the side panel body 5. The side edge portion 6c on one side in the left-right direction of the rear panel body 6 is connected to the rear edge portion 5d of the side panel body 5 disposed on one side in the left-right direction. The side edge portion 6d on the other side in the left-right direction of the rear panel body 6 is connected to the rear edge portion 5d of the side panel body 5 disposed on the other side in the left-right direction. A corner portion 61 is formed at the connection portion between the side panel body 5 and the rear panel body 6.

[0031] In this embodiment, the side panel body 5 and the rear panel body 6 each have frame portions 52, 62 (see FIG. 1) disposed on the inside, and skin materials 53, 63 (see FIG. 1) covering the frame portions 52, 62. The frame portion 52 of the side panel body 5 and the frame portion 62 of the rear panel body 6 are formed separately and are not connected. The skin material 53 of the side panel body 5 and the skin material 63 of the rear panel body 6 are formed integrally, or formed separately and connected by sewing or bonding. The rear panel body 6 and the pair of side panel bodies 5, 5 are formed integrally, with the respective skin materials 53, 63 connected to each other.

[0032] As shown in Figs. 5 to 7, the second support member 8 is a long member having an L-shaped cross section. The second support member 8 is made of steel or the like. The second support member 8 has a mounting portion 81, which is one piece constituting the L shape, and a pressing portion 82, which is the other piece. The mounting portion 81 is formed in a flat plate shape with a plate surface that is a long rectangle. As shown in Figs. 6 and 8, the mounting portion 81 is disposed along the lower surface of the second horizontal rod 42 with the plate surface being a horizontal plane and extending in the front-rear direction. The mounting portion 81 is fixed to the second horizontal rod 42 by a fixing device 83 such as a screw. The mounting portion 81 is formed with a hole portion 84 through which a screw or the like for fixing to the second horizontal rod 42 is inserted.

[0033] The mounting portion 81 protrudes laterally (outside in the left-right direction) beyond the second horizontal rod 42. In other words, the mounting portion 81 of the second support member 8 fixed to the second horizontal rod 42 of the frame structure 4 arranged on one side in the left-right direction of the seat 2 has a portion on the other side in the left-right direction arranged along the lower surface of the second horizontal rod 42, and a portion on one side in the left-right direction protrudes to one side in the left-right direction beyond the second horizontal rod 42. The mounting portion 81 of the second support member 8 fixed to the second horizontal rod 42 of the frame structure 4 arranged on the other side in the left-right direction of the seat 2 has a portion on one side in the left-right direction arranged along the lower surface of the second horizontal rod 42, and a portion on the other side in the left-right direction protrudes to the other side in the left-right direction beyond the second horizontal rod 42. The portion of the mounting portion 81 protruding laterally beyond the second horizontal rod 42 is referred to as the protruding portion 85, and the end portion on the protruding side (the outer end portion in the left-right direction) is referred to as the tip portion 851.

[0034] As shown in FIG. 6, the pressing portion 82 is formed in a flat plate shape with a plate surface that is a long rectangle. The pressing portion 82 has a plate surface that is a vertical plane, and is connected to the tip portion 851 of the mounting portion 81 in a direction extending in the front-rear direction. The pressing portion 82 protrudes upward from the tip portion 851 of the mounting portion 81. The pressing portion 82 faces the side surface of the second horizontal rod 42 with a gap in the left-right direction. The gap between the pressing portion 82 and the side surface of the second horizontal rod 42 is set to be approximately the same as the thickness dimension of the lower edge portion 5b of the side panel body 5. A groove portion 86 is formed between the second horizontal rod 42, the pressing portion 82, and the protruding portion 85 of the mounting portion 81. The lower edge portion 5b of the side panel body 5 is inserted from above into this groove portion 86. When the lower edge 5b of the side panel body 5 is inserted into the groove 86 from above, the side panel body 5 is placed on the protruding portion 85 of the placement portion 81, and the lower edge 5b is fitted and sandwiched between the pressing portion 82 and the second horizontal rod 42. The side panel body 5 supported by the second support member 8 can be removed from the second support member 8 by moving the side panel body 5 upward.

[0035] As shown in Figs. 5 and 6, the first support member 7 is inserted from the outside in the left-right direction into the first support member insertion hole 51 of the side panel body 5 and the first support member insertion recess 411 of the first horizontal rod 41, which are arranged overlapping in the left-right direction. In this embodiment, two first support members 7 are provided for one side panel body 5. As shown in Figs. 6 and 9, the first support member 7 has a frame fixing portion 71 that is inserted into the first support member insertion recess 411 (see Fig. 6) of the first horizontal rod 41 (see Fig. 6) and fixed to the first horizontal rod 41, a panel penetration portion 72 that is provided integrally with the frame fixing portion 71 and penetrates the first support member insertion hole 51 (see Fig. 6) of the side panel body 5 (see Fig. 6), and a panel pressing portion 73 that is provided integrally with the panel penetration portion 72 and arranged along the outer surface of the side panel body 5 in the left-right direction. The frame fixing portion 71 and the panel penetrating portion 72 are formed in a shape that allows them to penetrate the first support member insertion hole 51 of the side panel body 5. The frame fixing portion 71 is formed in a shape that allows them to be inserted into the first support member insertion recess 411. The panel pressing portion 73 is formed in a shape that is larger than the first support member insertion hole 51 and cannot penetrate the first support member insertion hole 51.

[0036] The frame fixing portion 71 is inserted into the first support member insertion recess 411 of the first horizontal rod 41 from the outside in the left-right direction, and is disposed on the lower plate portion 412 of the first horizontal rod 41. The frame fixing portion 71 is fixed to the lower plate portion 412 of the first horizontal rod 41 from the underside of the first horizontal rod 41 by a fastener 74 such as a screw. The panel pressing portion 73 is formed in a flat plate shape. When the panel penetration portion 72 penetrates the first support member insertion hole portion 51 of the side panel body 5, the panel pressing portion 73 is disposed along the outer surface of the side panel body 5 with the plate surface facing the left-right direction. The panel pressing portion 73 is disposed opposite the first horizontal rod 41 in the left-right direction. When the first support member 7 is fixed to the first horizontal rod 41, the left-right distance between the first horizontal rod 41 and the panel pressing portion 73 is approximately the same dimension as the thickness of the side panel body 5.

[0037] 10, it is possible to insert the frame fixing portion 71 and the panel penetration portion 72 into the first support member insertion recess 411 and fix the first support member 7 to the first horizontal rod 41 in a state where the panel pressing portion 73 contacts the first horizontal rod 41 without providing the side panel body 5 on the side of the first horizontal rod 41. In this state, the panel pressing portion 73 can cover the first support member insertion recess 411 of the first horizontal rod 41 from the side. Therefore, even when the side panel body 5 is removed, it looks good, and there is no need to store separately parts for attaching the side panel body 5 to the first horizontal rod 41 when the side panel body 5 is removed. Regarding the position at which the first support member 7 is fixed to the first horizontal rod 41, as shown in Fig. 6, the position at which the distance between the panel pressing portion 73 and the first horizontal rod 41 is approximately the same dimension as the thickness of the side panel body 5 is defined as the first position, and as shown in Fig. 10, the position at which the panel pressing portion 73 contacts the first horizontal rod 41 is defined as the second position. When supporting the side panel body 5, the first support member 7 is fixed to the first horizontal rod 41 at the first position, and when the side panel body 5 is not provided (removed), the first support member 7 is fixed to the first horizontal rod 41 at the second position.

[0038] When the side panel body 5 is disposed on the side (outside in the left-right direction) of the frame structure 4 and the first support member 7 is inserted into the first support member insertion hole portion 51 of the side panel body 5 and the first support member insertion recess portion 411 of the first horizontal rod 41 and fixed to the first horizontal rod 41, the side panel body 5 is sandwiched between the first horizontal rod 41 and the panel pressing portion 73 with the panel penetration portion 72 penetrating through. As a result, the side panel body 5 is fixed to the first horizontal rod 41. Note that the side panel body 5 can be removed from the first horizontal rod 41 by removing the first support member 7 from the first horizontal rod 41.

[0039] In this manner, the side panel body 5 is fixed to the first horizontal rod 41 by the first support member 7 and is fixed to the second horizontal rod 42 by the second support member 8 .

[0040] 4 and 8, in this embodiment, a rear panel body support member 92 that supports the lower edge portion 6b of the rear panel body 6 is fixed to the connecting member 46 located below the backrest portion 3. The rear panel body support member 92 is a member similar to the second support member 8. Note that, since the rear panel body 6 is formed integrally with the pair of side panel bodies 5, 5, it does not have to be fixed to the connecting member 46 by the rear panel body support member 92.

[0041] In the chair 1 according to the first embodiment, the first horizontal rod 41 and the second horizontal rod 42 of the frame structure 4 each extend in the front-rear direction (depth direction) and are arranged at different heights. This allows the side panel body 5 to be connected to the frame structure 4 at different heights. Also, the side panel body 5 can be connected to a plurality of locations (two locations in this embodiment) spaced apart in the front-rear direction at the height of the first horizontal rod 41, and can be connected to a predetermined range extending in the front-rear direction at the height of the second horizontal rod 42. This allows the side panel body 5 to be installed in a stable state. In this embodiment, the upper edge portion 5a of the side panel body 5 is located above the first horizontal rod 41, and the height dimension is larger than the dimension from the first horizontal rod 41 to the second horizontal rod 42. As described above, by fixing the side panel body 5 to the first horizontal rod 41 and the second horizontal rod 42, even a large-sized side panel body 5 can be installed in a stable state.

[0042] In the chair 1 according to the above-mentioned first embodiment, a second support member 8 (panel lower edge support member) that supports the lower edge 5b of the side panel body 5 is fixed to the second horizontal rod 42. With this configuration, the side panel body 5 can be stably connected to the second horizontal rod 42. Also, the side panel body 5 can be easily connected to the second horizontal rod 42 and can be easily removed from the second horizontal rod 42.

[0043] In the chair 1 according to the first embodiment described above, the first support member 7 (panel support member) is fixed to the first horizontal rod 41. The position at which the first support member 7 is attached to the first horizontal rod 41 can be selected from a first position (see FIG. 6) where the panel pressing portion 73 is arranged at a distance to the side of the first horizontal rod 41 and can press the side panel body 5, and a second position (see FIG. 10) where the panel pressing portion 73 contacts the first horizontal rod 41.

[0044] With this configuration, when the side panel body 5 is installed on the chair 1, the first support member 7 is fixed to the first horizontal rod 41 at the first position, so that the panel pressing portion 73 presses the side panel body 5 to support it on the first horizontal rod. When the first support member 7 is fixed to the first horizontal rod 41 at the second position, the panel pressing portion 73 can be prevented from protruding from the first horizontal rod 41. Therefore, when the side panel body 5 is not installed on the chair 1 (when the side panel body 5 is removed from the chair 1), the first support member 7 is fixed to the first horizontal rod 41 at the second position, so that the first support member 7 does not look strange in use or design even if it remains attached to the first horizontal rod 41. Therefore, when the side panel body 5 is not installed on the chair 1, there is no need to store the first support member 7 separately, making management easier. Furthermore, when the first support member 7 is fixed to the cross rod at the second position, the holes and metal fittings for fixing the first support member 7 to the first cross rod 41 (in this embodiment, the first support member insertion recess 411) are covered with the panel retaining portion 73, thereby improving the appearance of the chair 1 even when the side panel body 5 is not installed on the chair 1.

[0045] Furthermore, the chair 1 according to the above-described first embodiment is provided with a rear panel body 6 disposed behind the seat portion 2, and the rear panel body 6 is supported by the side panel body 5. With this configuration, by connecting the side panel body 5 to the frame structure 4, the rear panel body 6 can be installed behind the seat portion 2 without being connected to the backrest portion 3 or the like. Furthermore, by removing the side panel body 5 from the frame structure 4, the rear panel body 6 can also be removed.

[0046] In the chair 1 according to the first embodiment, the side panel body 5 and the rear panel body 6 are integrally formed. This configuration allows the panels (the side panel body 5 and the rear panel body 6) to be manufactured at low cost. Furthermore, when assembling the chair 1, there is no need to connect the side panel body 5 and the rear panel body 6, and the chair 1 can be easily assembled.

[0047] (Other embodiments) Next, other embodiments will be described based on the attached drawings. The same or similar components and parts as those in the first embodiment described above will be designated by the same reference numerals, and their description will be omitted. Only configurations that differ from the first embodiment will be described.

[0048] Second embodiment As shown in FIG. 11, in the chair 1B according to the second embodiment, the vertical dimension of the side panel body 5B is larger than that of the chair 1 according to the first embodiment shown in FIG. 1, and the lower edge portion 5b of the side panel body 5 is disposed at the height of the third horizontal rod 43. In the second embodiment, the second support member 8B is attached to the third horizontal rod 43, not to the second horizontal rod 42. The lower edge portion 5b of the side panel body 5B is supported by the third horizontal rod 43 via the second support member 8B. A gap is provided between the lower edge portion 5b of the side panel body 5B and the floor surface 12. In the second embodiment, the rear panel body 6 is also larger in the vertical dimension than the rear panel body 6 of the first embodiment, and the lower edge portion of the rear panel body 6 may be located near the floor surface 12. In the second embodiment, the third horizontal rod 43 corresponds to the "second horizontal rod extending in the depth direction below the first horizontal rod" of the present invention.

[0049] In the second embodiment, a corner fixing member 91 for fixing a corner 61 is attached to an upper end of the corner 61 at the connection portion between the side panel body 5B and the rear panel body 6. The corner fixing member 91 is made of steel or resin, and is configured to fix the corner 61 formed by the side panel body 5B and the rear panel body 6 at a predetermined angle so that the corner 61 does not open or close.

[0050] The chair 1B according to the second embodiment provides the same effects as the first embodiment, even when the lower edge 5b of the side panel body 5B is located at the height of the third horizontal rod 43 near the floor surface 12. Also, since the side panel body 5 is provided on the entire side of the chair 1 and can hide the frame structure 4 from the side, the design of the chair 1 can be improved.

[0051] In addition, in the chair 1B according to the second embodiment, a corner fixing member 91 for fixing the corner 61 is provided at the upper end of the corner 61 where the side panel 5B and the rear panel 6 are connected. With this configuration, the corner 61 between the side panel 5B and the rear panel 6 does not deform, and the shape of the panel can be maintained. This allows the side panel 5B and the rear panel 6 to be installed in a stable state.

[0052] In particular, the panel body (side panel body 5B and rear panel body 6) of the second embodiment is larger than the panel body (side panel body 5 and rear panel body 6) of the first embodiment. Therefore, in the second embodiment, when the side panel body 5B and the rear panel body 6 are manufactured integrally, the force that causes the side panel body 5B and the rear panel body 6 to spread so as to widen the angle of the corner 61 is also large. Therefore, in the second embodiment, by fixing the corner 61 formed by the side panel body 5B and the rear panel body 6 with the corner fixing member 91, it is possible to prevent the side panel body 5B and the rear panel body 6 from spreading. That is, in the second embodiment, it is particularly effective to provide the corner fixing member 91.

[0053] Third embodiment As shown in FIG. 12, in the chair 1C according to the third embodiment, the side panel body 5C extends further forward than the side panel body 5B of the second embodiment. The front edge portion 5c of the side panel body 5C is located forward of the first vertical rod 44. In the chair 1C according to the third embodiment, a front frame structure 47 is provided continuously in front of the frame structure 4. The front frame structure 47 has a first front horizontal rod 471 extending forward from the front end of the first horizontal rod 41, a second front horizontal rod 472 extending forward from the front end of the third horizontal rod 43, and a front vertical rod 473 extending in the vertical direction and connecting the front end of the first front horizontal rod 471 and the front end of the second front horizontal rod 472. The front portion of the side panel body 5C is supported by the front frame structure 47. The front portion of the side panel body 5C may be supported by a second support member 8 similar to that of the above embodiment provided on the second front horizontal rod 472. Also, the front portion of the side panel body 5C may be fixed to the first front horizontal rod 471 by a first support member 7. In the third embodiment, the first horizontal rod 41 and the first front horizontal rod 471 correspond to the "first horizontal rod extending in the depth direction above the seat surface" of the present invention, and the third horizontal rod 43 and the second front horizontal rod 472 correspond to the "second horizontal rod extending in the depth direction below the first horizontal rod" of the present invention.

[0054] In the chair 1C according to the third embodiment, the side panel body 5 extends forward, thereby making it possible to secure a large space for a user seated on the chair 1. Even in such a case, the same effects as those of the above embodiments can be obtained.
