[0003] [Patent Document 1] International Publication No. 2016 / 63826 Summary of the Invention [Problem to be solved by the invention]

[0004] However, for some users, the height of the functional components and the relative position of the installation surface do not match, making it uncomfortable to use. To address this, it is possible to prepare multiple types of fixtures with different relative positions between the functional components and the installation surface, or to equip the fixtures with complex adjustment mechanisms to adjust the relative positions between the functional components and the installation surface, but this is costly. The present invention aims to provide a furniture system that is low-cost and provides a comfortable usability for a variety of users. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention employs the following aspects. (1) A fixture system according to one aspect of the present invention comprises a fixture body and a spacer that is detachable from the fixture body and is installed on an installation surface, wherein the fixture body includes a functional member having a predetermined function and a support member that supports the functional member from below, and the spacer is detachable from the lower end of the support member, and the position of the functional member relative to the installation surface can be changed between a first state in which the spacer is not attached and a second state in which the spacer is attached to the lower end of the support member. According to this aspect, the position of the functional component relative to the installation surface can be changed by changing the first state in which the spacer is not attached to the second state in which the spacer is attached to the lower end of the support leg member. This makes it easy to prepare fixtures in the first state and the second state, which have different positions of the functional component relative to the installation surface, simply by changing whether or not the spacer is attached. Therefore, there is no need to prepare multiple types of fixtures with different relative positions of the functional component and the installation surface, or to provide each fixture with a height adjustment mechanism for the functional component. As a result, a fixture system that can be used comfortably by a variety of users can be provided at low cost.

[0006] (2) In the fixture system according to the aspect (1) above, it is preferable that the fixture body is a chair body, and the chair body is provided with a seating member having a seating surface as the functional member. According to this aspect, chairs in a first state and a second state, in which the position of the seating member relative to the installation surface is different, can be easily prepared simply by attaching or not attaching a spacer. Therefore, there is no need to prepare multiple types of chairs with different relative positions of the seating member relative to the installation surface, or to provide a height adjustment mechanism for the seating member. As a result, a furniture system that can be used comfortably by a variety of users can be provided at low cost.

[0007] (3) In the furniture system according to the aspect (2) above, the support leg member has a leg extending in the vertical direction, and the spacer has a spacer body having a first end formed on one horizontal side and a second end formed on the other horizontal side, and it is preferable that in the second state, the first end of the spacer body is connected to the lower end of the leg, and when viewed from above, the second end is positioned in a direction away from the center of the seating member relative to the first end. According to this aspect, the first end of the spacer body is connected to the bottom end of the leg, and the second end of the spacer body is positioned away from the center of the seating member relative to the first end, so that the second end of the spacer protrudes away from the center of the seating member. By contacting the installation surface with the protruding second end of the spacer in this manner, the stability of the chair is improved.

[0008] (4) In the fixture system according to the aspect (3) above, the support leg member further includes a contact member arranged below the leg, the contact member having a pad or roller that contacts the installation surface, and in the first state, the leg and the contact member are directly connected without the spacer, and in the second state, the first end is connected to the leg and the second end is connected to the contact member, so that the leg and the contact member are connected via the spacer. According to this aspect, in the second state, by attaching a spacer between the leg portion and the contact member, the position of the seating member relative to the installation surface can be easily changed from that in the first state.

[0009] (5) In the fixture system according to the aspect (4) above, the spacer has a first connecting portion that connects the first end to the leg in the second state, and a second connecting portion that connects the second end to the contact member at a position that protrudes horizontally to the other side from the lower end of the leg in the second state, and the leg has a connected portion to which the contact member is connected in the first state and to which the first connecting portion of the spacer is connected in the second state, and it is preferable that the contact member has a connecting portion that is connected to the connected portion in the first state and connected to the second connecting portion in the second state. According to this aspect, the receptacle portions of the legs are connected to the contact members in the first state and to the first connecting portions of the spacers in the second state. Furthermore, the connecting portions of the contact members are connected to the receptacle portions in the first state and to the second connecting portions in the second state. In this way, common receptacle portions and connecting portions can be used in the first state and the second state to connect the legs and contact members, the legs and spacers, and the contact members and spacers, respectively. This allows the legs and contact members to be used in common in the first state and the second state, contributing to cost reduction.

[0010] (6) In the fixture system according to the aspect (5) above, it is preferable that the connected portion is a female threaded hole, the first end portion has a through hole formed therein that penetrates the first end portion in the vertical direction, and the first connecting portion has a bolt that is fastened to the connected portion through the through hole. According to this aspect, by using a bolt as the first connecting portion, the first end of the spacer can be easily connected to the leg portion. Also, by using the bolt, the direction in which the second end on one horizontal side of the spacer extends relative to the first end on one horizontal side of the spacer can be adjusted, and the spacer can be fixed with the second end facing in any direction.

[0011] (7) In the fixture system according to the aspect (5) above, it is preferable that the connected portion is a female threaded hole, the first connecting portion is integrally formed with the first end portion so as to protrude upward from the first end portion, and has a male threaded portion that is fastened to the connected portion in the second state. According to this aspect, the first end of the spacer can be easily connected to the leg portion by fastening the male threaded portion of the first connecting portion into the female threaded hole, which is the connected portion.

[0012] (8) In the fixture system according to the aspect (3) above, in the second state, it is preferable that the first end of the spacer is connected to the lower end of the leg, and the second end, when viewed from above, is in direct contact with the installation surface at a position away from the center of the seating member relative to the first end. According to this aspect, in the second state, the first end of the spacer is connected to the lower end of the leg, and the second end is in direct contact with the installation surface, so that the spacer is interposed between the leg and the installation surface. This allows the seating member to be positioned higher relative to the installation surface in the second state than in the first state. Furthermore, when viewed from above, the second end of the spacer is in direct contact with the installation surface at a position away from the center of the seating member relative to the first end, thereby increasing the stability of the chair.

[0013] (9) In the fixture system according to the aspect (8) above, it is preferable that the spacer has a through hole that passes through the second end in the vertical direction, and in the second state, the second end is fixed to the installation surface by an anchor member that is driven into the installation surface through the through hole. According to this aspect, the second end of the spacer is fixed to the installation surface by the anchor member, so that the chair can be firmly fixed to the installation surface.

[0014] (10) In the fixture system according to the aspect (3) above, it is preferable that the spacer has a through hole formed therein that penetrates the second end in the vertical direction, and that in the second state, a contact member having a pad that contacts the installation surface is connected to the first end of the spacer so as to adjust the height of the seating member, and that an anchor member that is driven into the installation surface is fixed to the installation surface through the through hole. According to this aspect, in the second state, the first end of the spacer is interposed between the leg and the contact member, so the position of the seating member relative to the installation surface can be changed from the first state. Also, by driving an anchor member through a through-hole formed in the second end, which is positioned away from the center of the seating member relative to the first end, the spacer is firmly fixed to the installation surface, thereby increasing the stability of the chair.

[0015] (11) In the furniture system according to any one of the above aspects (2) to (10), it is preferable that the chair body further includes a connecting member extending in the left-right direction and connecting adjacent support leg members in the left-right direction, and that the plurality of seating members are arranged on the connecting member at intervals in the left-right direction. According to this aspect, in a chair in which multiple seating members are arranged at intervals in the left-right direction on a connecting member extending in the left-right direction, in the second state, the position of the seating members relative to the installation surface can be easily changed from the first state by attaching a spacer to the support leg member. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0018] (First embodiment) Fig. 1 is a perspective view of a chair 100B in a second state P2 configured by the furniture system 1A according to the first embodiment of the present invention, as seen from the front. Fig. 2 is a side view of the chair 100B in the second state P2 configured by the furniture system 1A. Fig. 3 is a side view of the chair 100A in a first state P1 configured by the furniture system 1A. As shown in FIGS. 1 to 3, the furniture system 1A includes a chair body (furniture body) 2 and a spacer 5A, and is installed on an installation surface F. The chair body 2 includes a lower structure 20 that is placed on a placement surface F such as a floor or the ground, and a plurality of seating members (functional members) 30.

[0019] In the following description, for convenience, the direction in which a person seated on the seating member 30 faces forward will be referred to as the "forward" direction, and the opposite direction will be referred to as the "rear" or "back side." Furthermore, the direction connecting the installation surface F side on which the furniture system 1A is installed and its opposite side will be referred to as the "vertical direction." Furthermore, the left-right direction of the furniture system 1A as seen from the person, i.e., the horizontal direction perpendicular to the front-to-back direction as seen from the vertical direction, will be referred to as the "left-right direction."

[0020] The lower structure 20 has a plurality of support leg members 21A and a connecting member 22. The plurality of support leg members 21A are provided spaced apart in the left-right direction. The plurality of support leg members 21A support the seating member 30 from below via the connecting member 22. In this embodiment, for example, two support leg members 21A are provided for one lower structure 20, but three or more support leg members 21A may also be provided for one lower structure 20.

[0021] Each support leg member 21A is provided on the installation surface F. In this embodiment, each support leg member 21A includes a pair of legs 23 and an adjuster (contact member) 40.

[0022] When viewed from the left-right direction, the pair of legs 23 branch out and extend downward from the upper end of the support leg member 21A in the front-rear direction. When viewed from the front-rear direction, each of the pair of legs 23 extends in the up-down direction. The front leg 23 is inclined gradually forward as it extends downward, and the rear leg 23 is inclined gradually backward as it extends downward. An adjuster 40 , which will be described in detail later, is provided at the lower end of each leg 23 .

[0023] As shown in Figures 2 and 3, a lower accommodating groove 21s recessed downward is formed in the upper end portion (where the leg portions 23 converge) of the support leg member 21A. The lower portion of the connecting member 22 is accommodated in the lower accommodating groove 21s. The support leg member 21A has locking portions 21k, 21j that protrude upward in front of and behind the connecting member 22 accommodated in the lower accommodating groove 21s. The locking portion 21k abuts against the connecting member 22 accommodated in the lower accommodating groove 21s from the front, and the locking portion 21j abuts against the connecting member 22 from the rear. The locking portions 21k, 21j restrict movement of the connecting member 22 in the front-to-rear direction.

[0024] The connecting member 22 extends in the left-right direction and connects adjacent support leg members 21A in the left-right direction. In this embodiment, the connecting member 22 has a rectangular cylindrical shape extending in the left-right direction. The connecting member 22 has a vertically long rectangular shape with a height in the up-down direction greater than a width in the front-to-rear direction. The lower part of the connecting member 22 is accommodated in the lower accommodation groove 21s. The upper part of the connecting member 22 protrudes upward from the upper surface of the support leg member 21A.

[0025] 1, the seating member 30 is provided on the connecting member 22. In this embodiment, for example, three seating members 30 are provided at intervals in the left-right direction. The number of seating members 30 may be one, two, or four or more. 2 and 3, the seating member 30 is provided above the connecting member 22. The seating member 30 has a predetermined function of allowing a person to sit on it, and includes a seat portion 31 and a backrest 32.

[0026] The seat portion 31 has a seat member 311 that faces upward and has a seating surface (functional surface) 31f on which an occupant sits, and a base member 312 that is provided below the seat member 311. The seat portion 31 is fixed via a pair of support brackets 33. The pair of support brackets 33 are provided at positions spaced apart in the left-right direction on the base member 312. Each support bracket 33 is formed integrally with the base member 312, for example. The support brackets 33 may be fixed to the underside of the base member 312 by a fixing means such as welding or bolting.

[0027] An upper accommodating groove 33s is formed on the underside of the support bracket 33, recessed upward and configured to accommodate the upper portion of the connecting member 22. The support bracket 33 has locking portions 33k, 33j that protrude downward in front of and behind the connecting member 22 accommodated in the upper accommodating groove 33s. The locking portion 33k abuts against the connecting member 22 from the front, and the locking portion 33j abuts against the connecting member 22 from the rear. The locking portions 33k, 33j restrict the movement of the support bracket 33 in the front and rear directions relative to the connecting member 22.

[0028] Each support bracket 33 accommodates the upper part of the connecting member 22 in the upper accommodation groove 33s, and is connected to the support leg member 21A via a bolt (not shown) or the like with its lower surface facing the upper surface of the support leg member 21A. In this way, the connecting member 22 is sandwiched between the support bracket 33 and the support leg member 21A, and the support bracket 33 is restricted from moving left and right relative to the connecting member 22. As a result, the seating member 30 is supported from below by the connecting member 22 via the support bracket 33.

[0029] The backrest 32 extends upward from the rear end of the seat portion 31. The upper portion of the backrest 32 extends upward and inclined obliquely backward.

[0030] 1, in this embodiment, an armrest 35 is provided between adjacent seating members 30 in the left-right direction. The armrest 35 is fixed to the connecting member 22 via an appropriate support bracket (not shown). Note that, instead of the armrests 35, other optional components such as a table or a power outlet may be provided between adjacent seating members 30 in the left-right direction. Also, the armrests 35 may not be provided between adjacent seating members 30 in the left-right direction.

[0031] In this furniture system 1A, the spacer 5A (see FIGS. 1 and 2) is detachably attached to the chair body 2. In this embodiment, the spacer 5A is detachably attached to the lower end of the support leg member 21A, between the leg 23 and the adjuster 40. The furniture system 1A can selectively configure a chair 100A in a first state P1 in which the spacer 5A is not attached, as shown in FIG. 3, or a chair 100B in a second state P2 in which the spacer 5A is attached between the leg 23 and the adjuster 40 at the lower end of the support leg member 21A, as shown in FIGS. 1 and 2. In the furniture system 1A of this embodiment, in the chair 100A in the first state P1, the leg 23 and the adjuster 40 are directly connected without the spacer 5A. In the furniture system 1A of this embodiment, in the chair 100B in the second state P2, the spacer 5A is attached between the leg 23 and the adjuster 40. Therefore, the seating member 30 of the chair 100B in the second state P2 is positioned higher from the installation surface F than the chair 100A in the first state P1. In other words, the spacer 5A has a function of changing the position of the seating surface 31f of the seating member 30 relative to the installation surface F between the first state P1 and the second state P2.

[0032] Fig. 4 is a diagram showing the lower end of support leg member 21A in the second state P2 in which spacer 5A is attached in the furniture system 1A. Fig. 5 is a diagram showing the lower end of support leg member 21A in the first state P1 in which spacer 5A is not attached in the furniture system 1A. 4 and 5, a female screw hole (connected portion) 27 is formed in the lower end of each leg portion 23 of the chair body 2. The female screw hole 27 is recessed upward from the lower surface of each leg portion 23.

[0033] The adjuster 40 is disposed below the leg portion 23. The adjuster 40 has a pad 41 that comes into contact with the installation surface F, and a screw shaft portion (connection portion) 42. The pad 41 has, for example, a circular shape when viewed from above. The lower surface of the pad 41 contacts the installation surface F. The pad 41 is formed in an umbrella shape with a diameter that gradually decreases from bottom to top. The pad 41 may have an anchor insertion hole 41h formed therein. An anchor (not shown) can be driven into the installation surface F through this anchor insertion hole 41h to fix the adjuster 40 to the installation surface F. The screw shaft portion 42 protrudes upward from the center when the pad 41 is viewed from above. A male screw groove is formed on the outer circumferential surface of the screw shaft portion 42. The lower end of the screw shaft portion 42 and the pad 41 may be connected via, for example, a ball joint (not shown) or the like so that the screw shaft portion 42 can tilt relative to the pad 41.

[0034] As shown in FIG. 4, the spacer 5A includes a spacer body 51, a bolt 55 as a first connecting portion, and a female screw portion 57 as a second connecting portion. The spacer body 51 has an oval shape when viewed from above, for example. The spacer body 51 has a predetermined height in the vertical direction. The height of the spacer body 51 in the vertical direction is preferably, for example, about 10 mm to 180 mm. Here, the heights of the spacer bodies 51 of the spacers 5A connected to the respective lower ends of the multiple legs 23 are the same.

[0035] The spacer body 51 has a first end 51s formed on one horizontal side and a second end 51t formed on the other horizontal side. A through-hole 54 that passes through the spacer body 51 from top to bottom is formed in the first end 51s of the spacer body 51.

[0036] In the second state P2, the first connecting portion connects the first end 51s of the spacer body 51 to the lower end of the leg 23. In this embodiment, the first connecting portion is a bolt 55. The bolt 55 is threaded from the underside of the spacer body 51 through the through hole 54 and into the female threaded hole 27 of the leg 23. Here, in this embodiment, an escape recess 51k recessed upward is formed on one horizontal side of the underside of the spacer body 51. The head 55a of the bolt 55 abuts against the underside of the spacer body 51 in the escape recess 51k. The head 55a is housed in the escape recess 51k, thereby preventing it from protruding downward from the spacer body 51.

[0037] In the second state P2, the second connecting portion connects the second end 51t to the adjuster 40 at a position that protrudes horizontally to the other side from the lower end of the leg portion 23. In the present embodiment, the second connecting portion is a female thread portion 57 formed on the second end 51t of the spacer main body 51. The female thread portion 57 is recessed upward from the lower surface of the spacer main body 51. The female thread portion 57 may be formed to penetrate the spacer main body 51 from top to bottom.

[0038] As shown in Figure 5, in this furniture system 1A, in chair 100A in first state P1 with spacer 5A not attached, threaded shaft 42 of adjuster 40 is screwed into female threaded hole 27 of leg 23. This connects leg 23 and adjuster 40 directly without spacer 5A in between.

[0039] 4, in furniture system 1A, in chair 100B in second state P2, bolt 55 inserted through through hole 54 is threaded into female threaded hole 27 of leg 23, thereby connecting first end 51s of spacer 5A to the lower end of leg 23. In addition, in second state P2, screw shaft 42 of adjuster 40 is threaded into female threaded portion 57, thereby connecting second end 51t of spacer 5A to adjuster 40. That is, chair 100B in second state P2 has seating surface 31f of seating member 30 higher by the height of spacer main body 51 than chair 100A in first state P1.

[0040] 2, in the second state P2, the spacer body 51 is disposed such that the second end 51t is positioned away from the center of the seating member 30 relative to the first end 51s connected to the lower end of the leg 23. In this embodiment, the spacer body 51 attached to the lower end of the front leg 23 has the second end 51t protruding forward relative to the first end 51s. The spacer body 51 attached to the lower end of the rear leg 23 has the second end 51t protruding rearward relative to the first end 51s.

[0041] In such furniture system 1A, the position of seating member 30 relative to the installation surface F can be changed between chair 100A in a first state P1 in which spacer 5A is not attached and chair 100B in a second state P2 in which spacer 5A is attached to the lower end of support member 21A. More specifically, the height of seating surface 31f of seating member 30 relative to the installation surface F differs between chair 100A in the first state P1 and chair 100B in the second state P2 in which spacer 5A is attached to the lower end of support member 21A. For example, in various facilities such as airports, train stations, and hospitals, both chairs 100A in the first state P1 without the spacer 5A and chairs 100B in the second state P2 with the spacer 5A attached to the lower end of the support leg member 21A are placed. As a result, for example, a user who feels that the seating surface 31f of the seating member 30 is too low in the chair 100A in the first state P1 or who finds it difficult to stand up from a seated position on the seating surface 31f can select and sit on the chair 100B in the second state P2. For example, when chairs 100A in the first state P1 are already installed in various facilities, it is also possible to provide the chair 100B in the second state P2 simply by attaching the spacer 5A to any one of the chairs 100A in the first state P1 selected from the multiple chairs 100A in the first state P1.

[0042] Thus, in this embodiment, the furniture system 1A comprises a chair body 2 and a spacer 5A that is detachable from the chair body 2, and is installed on an installation surface F, wherein the chair body 2 includes a seating member 30 having a seating surface 31f and a support member 21A that supports the seating member 30 from below, and the spacer 5A is detachable from the lower end of the support member 21A, and the position (vertical position) of the seating member 30 (seating surface 31f) relative to the installation surface F can be changed between a first state P1 in which the spacer 5A is not attached and a second state P2 in which the spacer 5A is attached to the lower end of the support member 21A. According to this configuration, the position (height) of the seating member 30 relative to the installation surface F can be changed by changing from the first state P1, in which the spacer 5A is not attached, to the second state P2, in which the spacer 5A is attached to the lower end of the support leg member 21A. For example, the position of the seating member 30 relative to the installation surface F can be made higher in the second state P2 than in the first state P1. As a result, for example, a user who finds it difficult to stand up from a seated position in the chair 100A in the first state P1 because the seating surface 31f is too low can select and sit in the chair 100B in the second state P2, in which the spacer 5A is attached, making it easier for even elderly people to stand up from a seated position. In this way, the chair 100A in the first state P1 and the chair 100B in the second state P2 can be configured simply by whether or not the spacer 5A is attached. Therefore, there is no need to prepare multiple types of chairs with different relative positions of the seating member 30 and the installation surface F, or to provide each chair with a complex adjustment mechanism for adjusting the height of the seating member 30. As a result, it is possible to provide a furniture system 1A at low cost that is comfortable for a variety of users to use.

[0043] In addition, the support leg member 21A has a leg portion 23 extending in the vertical direction, and the spacer 5A has a spacer body 51 having a first end portion 51s formed on one horizontal side and a second end portion 51t formed on the other horizontal side, and in the second state P2, the spacer body 51 is configured so that the first end portion 51s is connected to the lower end of the leg portion 23, and when viewed from above, the second end portion 51t is positioned in a direction away from the center of the seating member 30 relative to the first end portion 51s. According to this configuration, the first end 51s on one horizontal side of the spacer body 51 is connected to the lower end of the leg 23, and the second end 51t on the other horizontal side is disposed in a direction away from the center of the seating member 30 relative to the first end 51s, so that the second end 51t of the spacer 5A protrudes in a direction away from the center of the seating member 30. The protruding second end 51t of the spacer 5A comes into contact with the installation surface F in this manner, thereby increasing the stability of the chair 100B in the second state P2.

[0044] In addition, the support leg member 21A has a pad 41 that contacts the installation surface F and further includes an adjuster 40 arranged below the leg 23, and in the first state P1, the leg 23 and the adjuster 40 are directly connected without the spacer 5A, and in the second state P2, the first end 51s is connected to the leg 23 and the second end 51t is connected to the adjuster 40, so that the leg 23 and the adjuster 40 are connected via the spacer 5A. According to this configuration, in the second state P2, by attaching the spacer 5A between the leg portion 23 and the adjuster 40, the position of the seating member 30 relative to the installation surface F can be easily changed from that in the first state P1.

[0045] Furthermore, the spacer 5A has a bolt 55 as a first connection portion that connects the first end 51s to the leg 23 in the second state P2, and a female thread portion 57 as a second connection portion that connects the second end 51t to the adjuster 40 at a position that protrudes horizontally to the other side from the lower end of the leg 23 in the second state P2, the leg 23 has a female threaded hole 27 to which the adjuster 40 is connected in the first state P1 and to which the bolt 55 of the spacer 5A is connected in the second state P2, and the adjuster 40 has a screw shaft portion 42 that is connected to the female threaded hole 27 in the first state P1 and connected to the female thread portion 57 in the second state P2. According to this configuration, the female threaded hole 27 of the leg 23 is connected to the adjuster 40 in the first state P1, and is connected to the bolt 55 of the spacer 5A in the second state P2. The threaded shank 42 of the adjuster 40 is connected to the female threaded hole 27 in the first state P1, and is connected to the female threaded portion 57 in the second state P2. In this way, the common female threaded hole 27 and threaded shank 42 can be used in the first state P1 and the second state P2 to connect the leg 23 and the adjuster 40, the leg 23 and the spacer 5A, and the adjuster 40 and the spacer 5A, respectively. This allows the leg 23 and the adjuster 40 to be used in common in the first state P1 and the second state P2, which contributes to cost reduction.

[0046] In addition, a female threaded hole 27 is provided as the connected portion, and a through hole 54 is formed in the first end portion 51s, penetrating the first end portion 51s in the vertical direction, and a bolt 55 is provided as the first connecting portion, which is fastened to the female threaded hole 27 through the through hole 54. According to this configuration, the bolt 55 is used as the first connecting portion, and the first end 51s of the spacer 5A can be easily connected to the leg 23. Furthermore, by using the bolt 55, the direction in which the second end 51t on the other horizontal side of the spacer 5A extends can be adjusted relative to the first end 51s on one horizontal side of the spacer 5A, and the spacer 5A can be fixed with the second end 51t facing in any direction.

[0047] The chair body 2 further includes a connecting member 22 that extends in the left-right direction and connects adjacent support leg members 21A in the left-right direction, and a plurality of seating members 30 are provided on the connecting member 22 at intervals in the left-right direction. According to this configuration, in chairs 100A and 100B in which multiple seating members 30 are arranged at intervals in the left-right direction on a connecting member 22 extending in the left-right direction, in the second state P2, the position of the seating member 30 relative to the installation surface F can be easily changed from the first state P1 by attaching a spacer 5A to the support leg member 21A.

[0048] (Modification of the first embodiment) In the above embodiment, the support leg member 21A is provided with the adjuster 40 as a contact member below the leg portion 23, but the present invention is not limited to this. Fig. 6 is a diagram showing the lower end of support leg member 21B in second state P2 with spacer 5A attached in furniture furniture system 1B according to a modification of the first embodiment. Fig. 7 is a diagram showing the lower end of support leg member 21B in first state P1 with spacer 5A not attached in furniture furniture system 1B according to a modification of the first embodiment. For example, as shown in Figures 6 and 7, support leg member 21B of furniture system 1B in this modified example has caster 45 as a contact member below leg 23. Caster 45 has roller 46 that contacts installation surface F, holder 47 that supports roller 46 rotatably around a horizontal axis, and screw shaft 42 that protrudes upward from holder 47.

[0049] Even in the furniture system 1B equipped with such casters 45, the position (height) of the seating member 30 relative to the installation surface F can be changed between a chair 100A in a first state P1 in which the spacer 5A is not attached, as shown in Figure 7, and a second state P2 in which the spacer 5A is attached at the lower end of the support member 21B, between the leg 23 and the caster 45, as shown in Figure 6.

[0050] In such a caster 45, the threaded shank 42 is connected to the female threaded hole 27 in the first state P1, and in the second state P2, the threaded shank 42 is connected to the female threaded portion 57 serving as the second connecting portion. This allows the caster 45 to be used in common in both the first state P1 and the second state P2, which can contribute to cost reduction.

[0051] Second Embodiment Next, a second embodiment of the fixture system according to the present invention will be described. In the second embodiment described below, components common to the first embodiment will be denoted by the same reference numerals in the drawings, and their description will be omitted. FIG. 8 is a diagram showing the lower end of the support leg member 21C in the second state P2 in which the spacer 5C is attached in the furniture system 1C according to the second embodiment of the present invention. The fixture system 1C is configured to be switchable between a first state P1 in which the spacer 5C is not attached, as shown in Figures 5 and 7, and a second state P2 in which the spacer 5C is attached to the lower end of the leg 23, as shown in Figure 8.

[0052] In the first state P1, as in the first embodiment, as shown in FIGS. 5 and 7, the lower ends of the legs 23 may be provided with adjusters 40 or casters 45 as contact members.

[0053] 8, in the second state P2, the first end 51s of the spacer 5C is connected to the lower end of the leg 23 by the bolt 55. In the second state P2, the second end 51t of the spacer 5C is in direct contact with the installation surface F at a position spaced apart from the first end 51s in the front-to-rear direction when viewed from above.

[0054] Furthermore, the spacer 5C has a through-hole 54 that passes through the second end 51t in the vertical direction. In the second state P2, the second end 51t of the spacer 5C is fixed to the installation surface F by an anchor member 70 that is driven into the installation surface F through the through-hole 54.

[0055] In such a fixture system 1C, the position (height) of the seating member 30 relative to the installation surface F can be changed between a first state P1 in which the spacer 5C is not attached and a second state P2 in which the spacer 5C is attached to the lower end of the support member 21C. According to this configuration, the position of the seating member 30 relative to the installation surface F can be changed by changing from a first state P1 in which the spacer 5C is not attached to a second state P2 in which the spacer 5C is attached to the lower end of the support leg member 21C. In this way, by simply attaching and detaching the spacer 5C, it is possible to prepare chair 100A in the first state P1 and chair 100C in the second state P2. There is no need to prepare multiple types of chairs with different relative positions of the seating member 30 to the installation surface F or to provide each chair with a height adjustment mechanism for the seating member 30. Therefore, it is possible to provide a furniture system 1C that is comfortable to use for a variety of users at low cost.

[0056] In addition, in the second state P2, the first end 51s of the spacer 5C is connected to the lower end of the leg 23, and the second end 51t, when viewed from above, is in direct contact with the installation surface F at a position spaced apart in the front-to-back direction from the first end 51s. According to this configuration, in the second state P2, the first end 51s of the spacer 5C is connected to the lower end of the leg 23, and the second end 51t is in direct contact with the installation surface F, so that the spacer 5C is interposed between the leg 23 and the installation surface F. As a result, in the second state P2, by connecting the spacer 5C to the lower end of the leg 23, the position (height) of the seating member 30 with respect to the installation surface F can be easily changed compared to the first state P1. Furthermore, when viewed from above, the second end 51t of the spacer 5C is in direct contact with the installation surface F at a position spaced apart in the front-to-rear direction from the first end 51s, thereby improving the stability of the chair 100C.

[0057] In addition, the spacer 5C has a through hole 54 that passes through the second end 51t in the vertical direction, and in the second state P2, the second end 51t is fixed to the installation surface F by an anchor member 70 that is driven into the installation surface F through the through hole 54. According to this configuration, by fixing the second end 51t of the spacer 5C to the installation surface F with the anchor member 70, the chair 100C can be firmly fixed to the installation surface F.

[0058] (Modification of the second embodiment) In the second embodiment, the second end 51t of the spacer 5C is fixed to the installation surface F by the anchor member 70, but this is not limited to this. The second end 51t of the spacer 5C may simply be placed on the installation surface F without using the anchor member 70.

[0059] (Third embodiment) Next, a third embodiment of the fixture system according to the present invention will be described. In the third embodiment described below, components common to the first embodiment will be denoted by the same reference numerals in the drawings, and their description will be omitted. FIG. 9 is a diagram showing the lower end of the support leg member 21A in the second state P2 in which the spacer 5F is attached in the furniture system 1F according to the third embodiment of the present invention. The fixture system 1F is configured to be switchable between a first state P1 in which the spacer 5F is not attached, as shown in Figure 5, and a second state P2 in which the spacer 5F is attached to the lower end of the leg 23, as shown in Figure 9.

[0060] In the first state P1, as in the first embodiment, as shown in FIG. 5, the lower end of the leg 23 may be provided with a height-adjustable adjuster 40 having a pad 41 as a contact member.

[0061] 9, a first end 51s of a spacer body 51 of a spacer 5F according to this embodiment is provided with a male thread portion 59 as a first connecting portion. The male thread portion 59 is integrally formed with the first end 51s so as to protrude upward from the first end 51s. A female thread hole 58 is also formed in the first end 51s of the spacer body 51. The female thread hole 58 is recessed upward from the lower surface of the first end 51s of the spacer body 51.

[0062] In chair 100F in second state P2, male screw portion 59 is fastened to female screw hole 27 formed in the lower end of leg portion 23 of support leg member 21A. As a result, in second state P2, first end portion 51s of spacer 5F is connected to the lower end of leg 23. Also, in second state P2, screw shaft 42 of adjuster 40 is screwed into female screw hole 58 as a contact member. As a result, leg portion 23 and adjuster 40 are connected via first end portion 51s of spacer 5F. Adjuster 40 can adjust the height of leg 23 in accordance with the unevenness of the installation surface F.

[0063] Furthermore, the spacer 5F is formed with a through-hole 54 that passes through the second end 51t in the vertical direction. When viewed from above, the second end 51t is located at a position farther away from the center of the seating member 30 (see FIG. 2) than the first end 51s. In the second state P2, the height is adjusted according to the unevenness of the installation surface F using the adjuster 40 as a contact member, and then the second end 51t of the spacer 5F is fixed to the installation surface F by an anchor member 70 that is driven into the installation surface F through the through-hole 54.

[0064] In such a fixture system 1F, the position (height) of the seating member 30 relative to the installation surface F can be changed between a first state P1 in which the spacer 5F is not attached and a second state P2 in which the spacer 5F is attached to the lower end of the support member 21A. With this configuration, chair 100A in first state P1 and chair 100F in second state P2 can be prepared simply by attaching and detaching spacer 5F, eliminating the need to prepare multiple types of chairs with different relative positions between seating member 30 and installation surface F, or to provide each chair with a height adjustment mechanism for seating member 30. Therefore, a furniture system 1F can be provided at low cost that is comfortable for a variety of users.

[0065] In the second state P2, the first end 51s of the spacer 5F is interposed between the leg 23 and the adjuster 40, so the position of the seating member 30 relative to the installation surface F can be changed compared to the first state P1 (see FIGS. 5 and 7). In this case, the adjuster 40 can adjust the height of the seating member 30, so that unevenness of the installation surface F can be easily absorbed by adjusting the adjuster 40 provided on each leg 23. In addition, by driving anchor members 70 into the installation surface F through through holes 54 formed in the second end 51t, which is positioned at a distance in the front and rear from the first end 51s, the spacer 5F is firmly fixed to the installation surface F, thereby increasing the stability of the chair 100F.

[0066] (Other embodiments) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments.
