Summary of the Invention

Problems to be Solved by the Invention

[0005] In the seating furniture described in Patent Document 1, when attaching the seat member to the support structure (base frame), it is necessary to tighten the screw from the back side (lower side) of the support structure to the lower surface side (female screw part) of the seat member. However, when there is not enough space for screwing the screw below the support structure, the installation work by the operator becomes difficult.

[0006] Furthermore, when attaching the seat member to the support structure (frame), it is also possible to tighten the screws from the underside of the support structure (the side that will be the bottom surface when in use) with the support structure oriented sideways or upside down. However, in this case, since the support structure and seat member, which are heavy objects, are installed in a different orientation than when they are in use, workers will be forced to move heavy objects significantly when preparing to install the seat member and when the installation is completed.

[0007] Therefore, the present invention aims to provide a seating fixture that can be easily attached to a support structure, thereby improving assembly workability. [Means for solving the problem]

[0008] A seating fixture according to one aspect of the present invention is characterized by comprising: a support structure having a ground contact portion; a base member having a through hole penetrating in the vertical direction and supported on the upper part of the support structure; a fixing member that fixes the base member to the support structure from the upper side of the base member through the through hole; and a seating member that engages with the base member from above so as to cover at least a portion of the through hole and the upper side of the fixing member.

[0009] When assembling the seating unit according to this embodiment, the base member is placed on top of the support structure, and the fixing member is inserted into the through hole of the base member. In this state, the fixing member is operated from above the base member to fix the base member to the support structure. After this, the seat member is engaged with the base member from above. As described above, in this seating fixture, the seat member can be attached to the support structure from above the support structure.

[0010] The base member is preferably composed of a plate-shaped member extending in the horizontal direction.

[0011] In this case, the seat member can be easily installed on the upper surface of the base member, and the area of ​​the part exposed to the outside of the base member can be reduced.

[0012] The support structure comprises a plurality of leg columns having a ground contact portion at its lower end and rising upward from the ground contact portion, and a connecting frame connecting the upper parts of the plurality of leg columns, and the fixing member may be connected to the connecting frame.

[0013] In this case, the stability of the leg supports is enhanced by connecting multiple leg columns with ground contact points to a connecting frame at the top. Furthermore, by connecting the fixing members to the connecting frame positioned at the top of the support structure, the length of the fixing members can be shortened. Moreover, by adopting this configuration, it becomes possible to secure a relatively large foot space below the base member.

[0014] The leg columns have a plurality of pairs that are spaced apart in the depth direction of the seat member, the connecting frame has a plurality of front and rear frame sections that connect each pair of leg columns to each other, and a main frame section that connects the central regions of the plurality of front and rear frame sections, and the fixing member may be connected to the main frame section.

[0015] In this case, the rigidity of the connecting frame can be increased by the intersecting front and rear frame sections and the main frame section. Since the fixing member is connected to the main frame section of the connecting frame, which has thus increased rigidity, it becomes possible to stably support the seat member on the support structure. Furthermore, since the main frame is a component that connects the central regions of multiple front and rear frame components, the width of the main frame in the front-to-back direction tends to be narrower compared to the width of the base component in the depth direction. For this reason, it is relatively difficult to accurately position the base component at the connection point of the main frame component. However, in the seating fixture of this embodiment, a through-hole is formed in the base component that penetrates vertically, so the connection work of the fixing component to the main frame component can be easily performed while visually confirming the connection position through this through-hole.

[0016] The base member may be configured such that its front edge in the depth direction is positioned further forward in the depth direction than the main frame portion.

[0017] In this case, when the seating unit is viewed from above on the front side in the depth direction, the main frame is hidden by the base member and becomes difficult to see from the outside. Therefore, adopting this configuration makes it possible to improve the appearance quality of the seating unit.

[0018] The base member may comprise a base body into which the seating member engages from above, and a surface material attached to at least an area of ​​the outer surface of the base body that is exposed to the outside.

[0019] In this case, since at least the area of ​​the base body's outer surface that is exposed to the outside is covered with the surface material, it becomes possible to further improve the appearance quality of the seating fixture. In particular, when the surface material is applied to the front surface of the base body in the depth direction, the surface material is more likely to catch the eye when the seating fixture is viewed from above on the front side in the depth direction. Therefore, even if the connecting frame at the bottom of the base member is slightly visible, the connecting frame will be less of a concern to the viewer looking at the seating fixture.

[0020] The fixing member may be a bolt fastened to the support structure from above the base member through the through hole.

[0021] In this case, the base member can be easily and securely fixed to the support structure by tightening bolts into the support structure from above using a tool or the like.

[0022] The seat member may be engaged with the base member by an engaging portion formed by the engagement of a convex shape and a concave shape, which is provided between the upper surface of the base member and the back surface of the seat member.

[0023] In this case, after fixing the base member to the support structure by the fixing member, by simply pressing the seat member against a predetermined position on the base member from above and engaging the engaging portion between the seat member and the base member, the seat member can be easily engaged with the base member.

[0024] The engaging portion may be a surface fastener.

[0025] In this case, after fixing the base member to the support structure by the fixing member, by simply pressing the seat member against a predetermined position on the base member from above, the seat member can be easily engaged with the base member by the surface fastener. Also, since the engagement between the seat member and the base member is by the surface fastener, it becomes possible to easily adjust the attachment position etc. of the seat member.

Effect of the Invention

[0026] According to the seating furniture according to the present invention, the seat member can be easily attached to the support structure from the upper side without changing the orientation of the support structure. Therefore, when the seating furniture according to the present invention is adopted, the assembly workability can be improved. Also, in the seating furniture according to the present invention, since the seat member engaged with the base member from above has a structure that covers at least a part of the through holes and the upper part of the fixing member, it is possible to suppress a decrease in the appearance quality due to the access portion of the fixing member being visible from the outside.

Mode for Carrying Out the Invention

[0028] Embodiments of the present invention will be described below with reference to the drawings.

[0029] Figure 1 is a perspective view of the seating unit 1 of this embodiment, and Figure 2 is a side view of the seating unit 1. The seating unit 1 of this embodiment comprises a support structure 10 that is in contact with the floor surface F, a seat member 11 supported on the upper part of the support structure 10 to receive the load of the sitter, and a backrest 12 supported on the upper part of the support structure 10 to receive the load of the sitter's back. In the seating unit 1 of this embodiment, three seat members 11 are arranged in a row on the upper part of the support structure 10. Three backrests 12 are provided, corresponding to each seat member 11. In Figures 1 and 2, reference numeral 25 denotes a backrest cushion propped up against the front side of each backrest 12.

[0030] In this embodiment, the direction in which the three seat members 11 are arranged is referred to as the "chair width direction." Furthermore, with respect to the seating fixture 1, the direction perpendicular to the vertical direction and the chair width direction is referred to as the "depth direction," and within the depth direction, the side on which the backrest 12 is positioned relative to the seat members 11 is referred to as the "back side," and the opposite side is referred to as the "front side." Each diagram includes an arrow (UP) pointing to the top in the vertical direction, an arrow (FR) pointing to the front in the depth direction, and an arrow (LH) pointing to one side in the chair width direction.

[0031] Three base members 13 are mounted on the upper part of the support structure 10, arranged in the direction of the chair width. The base members 13 are plate-shaped members that extend horizontally and are formed in a rectangular shape when viewed from above. The three base members 13 are provided in correspondence with the three seat members 11. The width of the base members 13 in the direction of the chair width is formed to be approximately the same as the width of the seat members 11 in the direction of the chair width. A corresponding backrest 12 is fixedly installed on the upper surface of the rear side in the depth direction of each base member 13. The backrest 12 is formed so that its thickness in the depth direction gradually decreases from the bottom end upwards. The lower end of the backrest 12 is fixed to the upper surface of the base member 13 by bolt fastening. Although a detailed explanation in the diagram is omitted, the backrest consists of a core material made of wood or the like with cushioning material attached to its outer surface, and the cushion and the outside of the core material are covered with a surface material.

[0032] Figure 3 is a perspective view of the support structure 10. Figure 4 is a plan view with some components of the seating unit 1 (seat member 11, backrest 12, some base members 13, etc.) removed. Figure 5 is also a perspective view with some components of the seating unit 1 (seat member 11, backrest 12, etc.) removed. As shown in these figures, the support structure 10 comprises four leg columns 14 that are grounded on the floor surface F, and a connecting frame 15 that connects the upper parts of the four leg columns 14 to each other. The four leg columns 14 are positioned near the four corners of the seating unit 1, which has a rectangular shape in plan view. Each leg column 14 rises vertically upward from the ground contact portion 14a at its lower end. Pairs of leg columns 14 are spaced apart in the depth direction at one end and the other end of the seating unit 1 in the chair width direction, and the upper regions of each pair of leg columns 14 are connected by front and rear frame sections 16. Each front and rear frame section 16 extends along the depth direction of the seating unit 1. The central regions of the two front and rear frame sections 16 are connected in the depth direction by two main frame sections 17. The ends of the two main frame sections 17 are connected to the left and right front and rear frame sections 16 by welding or other means. These main frame sections 17 and front and rear frame sections 16 constitute the connecting frame 15 of this embodiment.

[0033] Each main frame section 17 is made of a rectangular tube having a flat upper wall 17u and extends linearly along the width direction of the chair. The two main frame sections 17 are spaced apart in the depth direction and are arranged to be parallel to each other at the same height. The width from the front edge of the front main frame section 17 in the depth direction to the rear edge of the rear main frame section 17 in the depth direction is set to be narrower than the depth extension length of the front and rear frame sections 16 (the spacing between the front and rear leg columns 14).

[0034] Three base members 13, which are square in plan view, are placed on the upper surfaces of the connecting frame 15 (two main frame sections 17 and left and right front and rear frame sections 16). Each base member 13 placed on the connecting frame 15 is fastened and fixed to the upper walls 17u of the two main frame sections 17 by bolts 18, which are fixing members, as shown in Figure 2.

[0035] In this embodiment, the base member 13 has a front-to-back width in the depth direction that slightly exceeds the installation positions of the front and rear leg columns 14. Therefore, the base member 13 placed on the connecting frame 15 completely covers the upper sides of the front and rear frame sections 16 and the main frame section 17. However, the front-to-back width of the base member 13 in the depth direction only needs to be wide enough to cover at least the space between the two main frame sections 17 and the upper surfaces of the two main frame sections 17.

[0036] Multiple screw holes 19 are formed in the upper walls 17u of the two main frame sections 17. Bolts 18 are tightened into each screw hole 19 to fix each base member 13 to the main frame section 17. Alternatively, through holes may be formed in the upper walls 17u of the main frame section 17, and nuts may be provided on the back side of the upper walls 17u. For example, two screw holes 19 are formed in the upper walls 17u of each main frame section 17 for one base member 13. However, the number of screw holes 19 is not limited to this.

[0037] As shown in Figures 4 and 5, each base member 13 has a through hole 20 that extends vertically through it, at a position corresponding to the threaded hole 19 of the main frame portion 17 of the support structure 10. This through hole 20 is a stepped hole, as shown in Figure 2. The shaft portion 18a of the bolt 18 is inserted into the through hole 20 from above. The tip of the shaft portion 18a of the bolt 18 inserted into the through hole 20 is then tightened into the corresponding threaded hole 19 of the main frame portion 17. If a nut is located on the back side of the upper wall 17u of the main frame portion 17, the bolt is then tightened into that nut.

[0038] The head 18b of the bolt 18 is housed in the stepped recess 21 at the top of the through hole 20. When the bolt 18 is tightened from above with a tool (not shown), the head 18b of the bolt 18 comes into contact with the bottom surface of the recess 21. As a result, the base member 13 is pressed down by the head 18b of the bolt 18, and in this state, the bolt 18 fastens and fixes it to the main frame 17.

[0039] Furthermore, the main frame portion 17 does not occupy the entire area in the depth direction below the base member 13 (its width in the depth direction is narrow). Therefore, when attaching the base member 13 to the main frame portion 17, it is relatively difficult to position the base member 13 precisely on the upper surface of the main frame portion 17. However, since the base member 13 has a through hole 20 that penetrates vertically, the worker performing the assembly can proceed with the assembly work while confirming the position of the main frame portion 17 through the through hole 20. In particular, in this embodiment, a stepped recess 21 is provided above the through hole 20 that penetrates the base member 13 vertically, so the position of the main frame portion 17 can be easily visually confirmed through the recess 21 with a large outer diameter. Therefore, when this configuration is adopted, the assembly work can be performed more easily.

[0040] As shown in Figure 5, the base member 13, which is fastened and fixed to the main frame portion 17 of the support structure 10 in this manner, has its front edge in the depth direction positioned in front of the main frame portion 17 in the depth direction. Before bolting the base member 13 to the main frame 17 in this manner, the backrest 12 is pre-fixed to the upper surface on the rear side in the depth direction by bolting.

[0041] As shown in Figure 5, one of the engaging surfaces of the hook-and-loop fastener 30, which is an engaging member, is attached to the upper surface of the base member 13. In addition, an engaging surface (not shown) that is paired with the engaging surface of the hook-and-loop fastener 30 on the base member 13 is attached to the back surface (bottom surface) of the seat member 11 which is placed on the upper surface of the base member 13. The hook-and-loop fastener 30 is an engaging member in which a plurality of fine hook-shaped portions (protrusions) and loop-shaped portions (recesses) are provided on the pair of engaging surface portions. The hook-and-loop fastener 30 works by pressing the pair of engaging surface portions against each other, so that the protrusions and recesses on both engaging surface portions are locked together.

[0042] As described above, a seat member 11 is attached from above to the upper surface of each base member 13 fixed on the support structure 10 via a hook-and-loop fastener 30. The seat member 11's movement relative to the base member 13 is restricted by the engagement of the pair of engaging surfaces of the hook-and-loop fastener 30 at the convex and concave portions. The seat member 11, thus attached to the upper surface of the base member 13, covers the through holes 20 on the base member 13 and the heads 18b of the bolts 18 (fixing members). In this embodiment, the seat member 11 is attached to the upper surface of the base member 13 so as to cover all the through holes 20 and the heads 18b of the bolts 18. In this embodiment, a hook-and-loop fastener 30 is used as a means for engaging the seat member 11 with the base member 13 from above. However, other means besides the hook-and-loop fastener 30 can be used to engage the seat member 11 with the base member 13. As this engaging part, it is also possible to use an engaging part made of resin, metal, etc., which consists of a relatively large convex shape and a concave shape. For example, a snap-button-shaped engaging part or an engaging part consisting of a claw and a recess (hole) can also be used.

[0043] Furthermore, as shown in Figure 5, the base member 13 comprises a base body 35 into which the seat member 11 engages from above, and a surface material 40 attached to the periphery and upper and lower edges of the base body 35. The base body 35 is the main component of the base member 13, supporting the seat member 11 and the backrest 12, and receiving the seating load. The base body 35 is formed from, for example, wood. The surface material 40 is a member that covers the area of ​​the base body 35 that is exposed to the outside, and is formed from, for example, cloth, leather, synthetic leather, etc.

[0044] As described above, in this embodiment, the seating unit 1 has a base member 13 positioned on the upper part of the support structure 10, and the base member 13 is provided with a through hole 20 that penetrates vertically. A bolt 18 (fixing member) for fixing the base member 13 to the support structure 10 can be inserted from above into the through hole 20 of the base member 13. In addition, the seat member 11 is engaged with the base member 13 from above. For this reason, the seating unit 1 can be assembled as follows.

[0045] When assembling the seating unit 1, the base member 13 is placed on top of the support structure 10, and the shaft portion 18a of the bolt 18 is inserted into the through hole 20 of the base member 13. In this state, the bolt 18 is tightened from above the base member 13 using a tool, and the base member 13 is fixed to the support structure 10 by the bolt 18. After this, the seating member 11 is engaged with the base member 13, which is fixed to the top of the support structure 10, from above the base member 13.

[0046] Therefore, in the seating fixture 1 of this embodiment, the seat member 11 can be easily assembled to the support structure 10 from above without changing the orientation of the support structure 10. Thus, by adopting the seating fixture 1 of this embodiment, assembly workability can be improved. Furthermore, in the seating fixture 1 of this embodiment, the seating member 11, which engages with the base member 13 from above, is structured to cover the through hole 20 and the head 18b of the bolt 18. This suppresses a decrease in appearance quality due to the access portion of the bolt 18 being visible from the outside.

[0047] Furthermore, in this embodiment, the seating fixture 1 has a base member 13 on which the seat member 11 engages, and this base member is made up of a plate-shaped member that extends horizontally. Therefore, when this configuration is adopted, it becomes possible to easily install the seat member 11 on the upper surface of the base member 13, and it becomes possible to reduce the area of ​​the part of the base member 13 that is exposed to the outside.

[0048] Furthermore, in the seating fixture 1 of this embodiment, the support structure 10 is configured to include a plurality of leg columns 14 that rise upward from the ground contact portion 14a, and a connecting frame 15 that connects the upper parts of the plurality of leg columns 14. The fixing members (bolts 18) for fixing the base member 13 to the support structure 10 are connected to the connecting frame 15. In this configuration, since the plurality of leg columns are connected to a common connecting frame at the upper side, the installation stability of the leg columns can be increased. Furthermore, in this configuration, since the fixing member (bolt 18) is connected to the connecting frame 15 located on the upper part of the support structure 10, the length of the fixing member (bolt) can be shortened. Furthermore, in this configuration, since the fixing member (bolt 18) is connected to the connecting frame 15 located on the upper part of the support structure 10, a relatively large foot space can be secured below the base member 13.

[0049] Furthermore, in this embodiment, the seating fixture 1 has a configuration in which the connecting frame 15 of the support structure 10 comprises front and rear frame sections 16 that connect the front and rear leg columns 14 in the depth direction to each other, and a main frame section 17 that connects the central regions of the multiple front and rear frame sections 16. The fixing members (bolts 18) for fixing the base member 13 to the support structure 10 are connected to the main frame section 17. In this configuration, the rigidity of the connecting frame 15 can be increased by the intersecting front and rear frame sections 16 and the main frame section 17. The fixing members (bolts 18) are connected to the main frame section 17 of the connecting frame 15, which has thus increased rigidity. Therefore, when the seating fixture 1 of this embodiment is adopted, the seat member 11 can be stably supported by the support structure 10.

[0050] Furthermore, in the seating unit 1 of this embodiment, the front edge of the base member 13 in the depth direction is positioned further forward in the depth direction than the front main frame portion 17 of the support structure 10. Therefore, when the seating unit 1 is viewed from above on the front side in the depth direction, the main frame portion 17 is hidden by the front edge of the base member 13 and is difficult to see from the outside. Therefore, by adopting the seating fixture 1 of this embodiment, it becomes possible to improve the appearance quality of the seating fixture 1.

[0051] Furthermore, the base member 13 of the seating fixture 1 in this embodiment includes a base body 35 into which the seat member 11 engages from above, and a surface material 40 attached to at least the area of ​​the outer surface of the base body 35 that is exposed to the outside. As a result, the base body 35 of the base member 13, which is made of wood or the like, is not directly exposed to the outside. Therefore, by adopting this configuration, it is possible to further improve the appearance quality of the seating fixture 1. In particular, in the seating unit 1 of this embodiment, the front side and the sides of the base member 13 in the depth direction are reliably covered by the surface material 40, so when the seating unit 1 is viewed from above on the front side in the depth direction, the surface material 40 is more likely to catch the eye. Therefore, even if the connecting frame 15 below the base member 13 is slightly visible, the connecting frame 15 is less likely to be a concern for the viewer of the seating unit 1.

[0052] Furthermore, in this embodiment, the seating fixture 1 uses a bolt 18 as a fixing member to secure the base member 13 to the support structure 10. The shaft portion 18a of the bolt 18 is inserted through the through hole 20 of the base member 13 and fastened to the support structure 10. Therefore, the base member 13 can be easily and reliably fixed to the support structure 10 by tightening the bolt 18 into the support structure 10 from above using a tool or the like.

[0053] Furthermore, in this embodiment, the seating fixture 1 engages the seat member 11 and the base member 13 using an engaging portion (hook-and-loop fastener 30) with a convex shape and a concave shape. Therefore, after fixing the base member 13 to the support structure 10 with a fixing member (bolt 18), the seat member 11 can be easily engaged with the base member 13 by simply pressing the seat member 11 onto a predetermined position on the base member 13 from above to engage the convex and concave shapes of the engaging portion (hook-and-loop fastener 30).

[0054] In particular, in the seating fixture 1 of this embodiment, hook-and-loop fasteners 30 are used as the engaging part, which is formed by the engagement of a convex shape and a concave shape. Therefore, after fixing the base member 13 to the support structure 10 with a fixing member (bolt 18), the seat member 11 can be easily engaged with the base member 13 by simply pressing the seat member 11 onto a predetermined position on the base member 13 from above using the hook-and-loop fasteners 30. Furthermore, when this configuration is adopted, the engagement between the seat member 11 and the base member 13 is made by hook-and-loop fasteners 30, which allows for easy adjustment of the mounting position of the seat member 11, making it possible to engage the seat member 11 with the appropriate position on the base member 13.

[0055] It should be noted that the present invention is not limited to the embodiments described above, and various design modifications are possible without departing from the spirit of the invention. For example, in the above embodiments, a seating unit equipped with a backrest 12 is used, but the backrest 12 is not necessarily required.

[0056] Furthermore, in the above embodiment, a bolt 18 is used as a fixing member to secure the base member 13 to the support structure 10, but the fixing member is not limited to a bolt. The fixing member may be a clip or the like, as long as it can be used to secure the base member 13 to the support structure 10 from the upper side through the through hole 20.

[0057] Furthermore, in the above embodiment, a hook-and-loop fastener 30 is used as a means for engaging the seat member 11 with the upper surface of the base member 13 from above, but this means is not limited to a hook-and-loop fastener 30. As a means for engaging the seat member 11 with the upper surface of the base member 13 from above, it may also be an engagement between a recess and a protrusion that are fitted together by pressing the seat member 11 from above.

[0058] Furthermore, in the above embodiment, the seating member 11 is attached to the base member 13 so as to cover all the through holes 20 and the heads 18b of the bolts 18. However, it is sufficient if the seating member 11 can cover at least some of the through holes 20 and the top of the bolts 18 (fixing members).

[0059] Furthermore, in the above embodiment, bolt fastening is used as a means of attaching the backrest 12 to the base member 13, but the means of attaching the backrest 12 to the base member 13 is not limited to bolt fastening. The backrest 12 can also be attached using hook-and-loop fasteners 30, for example, in the same way as the seat member 11. In this case, the backrest 12 can be easily attached from above together with the seat member 11 using the same hook-and-loop fasteners 30. Therefore, if this configuration is adopted, it is possible to improve the assembly efficiency of the seating unit 1. Moreover, in this case, by using hook-and-loop fasteners 30, it becomes possible to easily adjust the attachment position of the backrest 12. [Explanation of Symbols]
