Description

[Technical Field]

[0001] The present invention relates to a furniture unit with a top and a furniture unit. [Background technology]

[0002] In offices, public facilities, etc., furniture with tops such as desks and tables are used to provide workers with work areas. Furniture with tops is generally placed close to the tops of adjacent furniture with tops or to the sides of other installed objects such as walls and partitions of facilities, without any gaps.

[0003] However, the use of tabletop fixtures is not limited to this usage, and there are also cases where a gap is provided between the edge of the tabletop and other installed objects, for example, to allow the wiring of electronic devices such as computers used on the tabletop to be pulled downward. In this case, if a gap is simply provided between the edge of the tabletop and other installed objects, the tabletop fixture may move while the worker is using it, causing the gap to deviate from the initial setting.

[0004] For this reason, fixtures with tabletops have been devised that are equipped with removable or movable (protruding / storing) position-regulating members (spacers) that can regulate the distance (gap) between the tabletop and other adjacent installed objects to a certain distance (see, for example, Patent Documents 1 to 3).

[0005] The fixture with a tabletop described in Patent Document 1 has a position restricting member rotatably attached to the underside of the tabletop near the edge. In this fixture with a tabletop, when a gap is to be secured between the fixture and an adjacent installed object, the position restricting member is rotated so that it protrudes outward from the edge of the tabletop, and the edge of the position restricting member abuts against the adjacent installed object. When no gap is to be secured between the fixture and the adjacent installed object, the position restricting member is returned to the storage position, and the edge of the tabletop directly abuts against the installed object.

[0006] The tabletop-equipped fixture described in Patent Document 2 has a position restricting member rotatably attached to the lower region (region close to the floor) of a support structure that supports the tabletop from below. Furthermore, the tabletop-equipped fixture described in Patent Document 3 has a position restricting member detachably attached to the lower region of a similar support structure. When these tabletop-equipped fixtures require a gap between adjacent installed objects, the position restricting member is rotated so that it protrudes outward from the edge of the tabletop, or the position restricting member is attached and the edge of the position restricting member abuts against the adjacent installed object. When no gap is required between adjacent installed objects, the position restricting member is returned to the storage position or removed, and the edge of the tabletop is directly abutted against the installed object. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 4313158 [Patent Document 2] Patent No. 6508811 [Patent Document 3] Patent No. 6501386 Summary of the Invention [Problem to be solved by the invention]

[0008] Incidentally, in the case of fixtures with tabletops, there is a demand for a continuous gap to be secured on the rear and sides of the tabletop in the depth direction, from the standpoint of facilitating the routing of wiring cables and the installation of clamp fittings for fixing options. For example, when pulling the wiring cable of an electronic device such as a computer on a tabletop downward through a gap at the back of the tabletop in the depth direction, if the wiring cable can be pulled downward from the front of the tabletop in the depth direction, and then pulled through a gap on the side of the tabletop into the gap at the back of the depth direction, the work of pulling the wiring cable will be easier. Furthermore, when attaching an optional part such as a monitor stand to the rear edge of the tabletop in the depth direction, the clamp fittings for fixing the option can be engaged with the side edge of the tabletop before tightening, and then the clamp fittings can be moved from that state via the side gap to the rear gap, making the clamp fitting installation work easier.

[0009] However, the fixtures with tabletops described in Patent Documents 1 to 3 use a positioning member to adjust the gap between one edge of the tabletop and an adjacent installed object, so if you want to ensure a continuous gap on the back and sides of the tabletop in the depth direction, it becomes necessary to install multiple positioning members. In this case, the number of parts increases and the installation work becomes complicated, so improvements in these areas are desired.

[0010] Therefore, the present invention aims to provide a fixture with a tabletop and a fixture unit that can ensure a continuous gap between two adjacent edges of the tabletop and other installed objects using a single position-regulating member, and that can switch between having or not having a gap and increasing or decreasing the size of the gap. [Means for solving the problem]

[0011] In order to solve the above problems, the furniture with a top and the furniture unit according to the present invention employ the following configuration. In other words, one aspect of the present invention provides a fixture with a top plate comprising a top plate, a support structure that is grounded on the floor surface and supports the top plate from below, and a position regulating member that can regulate the horizontal distance between the top plate and an installed object placed adjacent to the top plate to a fixed distance, wherein the top plate has a first edge that faces one side in a planar view, and a second edge that is adjacent to the first edge in a planar view and faces a different direction from the first edge, and the position regulating member has a first regulating portion that is connected to or abuts the installed object to regulate the distance between the first edge of the top plate and the installed object to a fixed distance, and a second regulating portion that is connected to or abuts the installed object to regulate the distance between the second edge of the top plate and the installed object to a fixed distance, and wherein the position regulating member is detachable from the support structure, or can be attached so that the positions of the first regulating portion and the second regulating portion can be adjusted.

[0012] In this type of fixture with a countertop, to ensure a certain gap between the countertop and an installed object, a position restricting member is attached to the support structure, or the position of a position restricting member already attached to the support structure is adjusted to a position that ensures the gap. As a result, the first restricting portion of the position restricting member is connected to or abuts against the installed object, thereby restricting the distance between the first edge of the countertop and the installed object to a certain distance. At this time, the second restricting portion of the position restricting member is connected to or abuts against the installed object, thereby restricting the distance between the second edge of the countertop and the installed object to a certain distance. To eliminate or reduce the gap between the tabletop and the installed object, the position restricting member is removed from the support structure or the position of the position restricting member previously attached to the support structure is adjusted to the release position. As a result, the distance between the first edge of the tabletop and the installed object is no longer restricted by the position restricting member, and the distance between the second edge of the tabletop and the installed object is also no longer restricted by the position restricting member. Therefore, when a fixture with a tabletop of this type is adopted, a single position control member makes it possible to ensure a continuous gap between the two adjacent edges of the tabletop and other installed objects, and also makes it possible to switch between having a gap or not, or increasing or decreasing the size of the gap.

[0013] When the position regulating member regulates the distance between the first and second edges of the tabletop and the installed object to a fixed distance, the first regulating portion may protrude further outward from the tabletop than the first edge, and the second regulating portion may protrude further outward from the tabletop than the second edge.

[0014] In this case, the first restricting portion, which protrudes outward from the top plate beyond the first edge of the top plate, is connected to or abuts against the adjacent installation portion, thereby ensuring a certain gap between the first edge of the top plate and the other installed object. Also, the second restricting portion, which protrudes outward from the top plate beyond the second edge of the top plate, is connected to or abuts against the adjacent installation portion, thereby ensuring a certain gap between the second edge of the top plate and the other installed object. As a result, a continuous gap is reliably ensured between the adjacent first and second edges of the top plate and the other installed object.

[0015] The support structure may include a lower support extending along the floor surface at a position close to the floor surface, and the position regulating member may be attached to the lower support so as to be detachable or so that the positions of the first regulating portion and the second regulating portion can be adjusted.

[0016] In this case, the positioning member is attached to the lower support that extends to a position close to the floor, so the positioning member can also be placed at a sufficiently low position close to the floor. As a result, the positioning member does not occupy the main space below the tabletop, making the tabletop-equipped fixture easier to use.

[0017] The position restricting member may also be provided with a flat article placement surface on the top surface of which an article can be placed when the position restricting member restricts the separation distance between the top plate and the installed object to a fixed distance.

[0018] In this case, the position restricting member positions the item placement surface at a position sufficiently close to the floor surface adjacent to the lower support, making it possible to stably place items such as wiring devices in a low position close to the floor surface below the top plate, which is likely to become dead space.

[0019] The support structure may further include a pedestal extending upward from the lower support and supporting the tabletop at an upper portion thereof, the pedestal being provided with an extension mechanism for adjusting the elevation of the tabletop.

[0020] In this case, the telescopic mechanism of the legs allows the height of the tabletop to be adjusted to any height, improving usability for users of the tabletop-equipped furniture. Furthermore, because the positioning member is attached to the part of the legs that does not move up or down (the lower support) as they extend or retract, the height does not fluctuate as the tabletop moves up or down. This makes it possible to consistently maintain a continuous gap along the two adjacent edges (the first edge and the second edge) of the tabletop. Furthermore, when a tabletop-equipped fixture is installed adjacent to another installed object and the tabletop is raised or lowered, there is a concern that an item may become caught between the rising or lowering tabletop and the other installed object. However, in the tabletop-equipped fixture of this configuration, a position control member attached to the lower support, rather than the tabletop, ensures a sufficient gap between the rising or lowering tabletop and the other installed object. Therefore, when the tabletop-equipped fixture of this embodiment is adopted, it is possible to prevent an item from becoming caught between the tabletop and the other installed object as it rises or falls.

[0021] The position restricting member may include a connecting portion that is connected to the installation object so as to restrict the separation distance between the top plate and the installation object to a fixed distance.

[0022] In this case, by connecting the connecting portion of the position control member to the other installed object, the position control member is less likely to come off the other installed object, and it is possible to reliably maintain a constant gap between the edge of the top plate and the other installed object.

[0023] The position restricting member may have an abutting surface that abuts against the object so as to restrict the separation distance between the top plate and the object to a fixed distance.

[0024] In this case, simply by bringing the contact surface of the position restricting member into contact with the other installed object, it is possible to easily ensure a certain gap between the edge of the top plate and the other installed object.

[0025] The display fixture with a tabletop as described in claim 2, characterized in that the position regulating member is attachable to the support structure so that either the first regulating portion or the second regulating portion protrudes further inward from the tabletop than the corresponding first edge or second edge.

[0026] In this case, if the position restricting member is attached to the support structure so that one of the first and second restricting parts protrudes inward from the edge of the tabletop (so that it protrudes in the opposite direction from normal), it becomes possible to position one edge of the tabletop close to another installed object. Also, because one of the first and second restricting parts protrudes inward from the tabletop, this protruding part can function as a stopper for a cart placed below the tabletop, for example.

[0027] Furthermore, a fixture unit according to one aspect of the present invention comprises a first fixture with a tabletop and a second fixture with a tabletop, each of which has a tabletop and a support structure that is in contact with the floor surface and supports the tabletop from below, and which are arranged facing each other, and a position restricting member that can restrict the horizontal separation distance between the tabletops of the first fixture with a tabletop and the second fixture with a tabletop, and when the direction in which the two tabletops face each other in a plan view is defined as a first direction and a direction intersecting the first direction is defined as a second direction, each of the tabletops has a first edge that is arranged facing the opposing tabletop in the first direction, and an adjacent edge that is on the same side in the extension direction of each of the first edges of the two tabletops. The position regulating member has a first extension portion connected to each of the support structures of the first tabletop-equipped fixture and the second tabletop-equipped fixture to regulate the separation distance between the two tabletops at a constant value, and a second extension portion connected to the first extension portion and protruding outside each of the tabletops beyond the second edge of each of the tabletops, and the position regulating member is detachably attached to the two support structures, and the protruding end of the second extension portion is capable of abutting or being connected to an installed object arranged adjacent to the first tabletop-equipped fixture and the second tabletop-equipped fixture in the second direction.

[0028] In this fixture unit, when the first edges of the first and second tabletop-equipped fixtures are aligned and a certain gap is required between the two tabletops, the first extension of the positioning member is connected to the support structure for the first and second tabletop-equipped fixtures. This allows the first extension of the positioning member to regulate the distance between the two tabletops to a certain distance. Furthermore, when the positioning member is connected to the support structure for the first and second tabletop-equipped fixtures, the protruding end of the second extension of the positioning member protrudes beyond the second edges of the two tabletops. In this state, when the protruding end of the second extension is abutted against or connected to an object located adjacent to the first and second tabletop-equipped fixtures on the second direction side, the distance between the two tabletops and the object is regulated to a certain distance. As a result, a continuous gap is ensured between the first edges of the two tabletops and between the second edges of each tabletop and the adjacent installed object. Furthermore, when the first edges of the first and second tabletop fixtures are placed facing each other to eliminate or reduce the gap between the two tabletops, the two tabletop fixtures are directly butted together without attaching positioning members to the support structures of the two tabletop fixtures. This eliminates or reduces the gap between the tabletops of the two tabletop fixtures. Furthermore, when positioning members are not attached to the two tabletop fixtures in this way, the second extension of the positioning member does not protrude outward from the second edges of the two tabletops, so the two tabletops are placed close to adjacent installed objects. This eliminates or reduces the gap between the second edges of the two tabletops and the installed objects. Therefore, when a fixture unit of this type is adopted, a single position control member makes it possible to ensure a continuous gap between the first edges of two opposing tabletops and between the second edges of each tabletop, and also makes it possible to switch between having or not having a gap and increasing or decreasing the size of the gap. [Effects of the Invention]

[0029] According to the present invention, a single position control member can ensure a continuous gap between the two adjacent edges of the tabletop and other installed objects, and can also switch between having or not having a gap and increasing or decreasing the size of the gap.

[0031] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In each embodiment described below, common parts are denoted by the same reference numerals, and some overlapping explanations will be omitted.

[0032] First Embodiment FIG. 1 is a perspective view of a furniture system 1 in which two furniture units 1A and 1B are combined, and FIG. 2 is a plan view of the same furniture system 1. As shown in FIG. Each of the furniture units 1A and 1B has two furniture units 10 with tabletops of the same configuration arranged facing each other. The furniture system 1 of this embodiment is configured by combining four furniture units 10 with tabletops.

[0033] Each fixture 10 with a tabletop comprises a tabletop 11 that is rectangular in plan view, a support structure 12 that is grounded to the floor surface F and supports the tabletop 11 from below, and a position control member 13 that can control the horizontal separation distance (separation distance in plan view) between the tabletops 11 of adjacent fixtures 10 with tabletops that are arranged to a fixed distance. Hereinafter, the direction in which the longer side of the rectangular tabletop 11 in plan view extends will be referred to as the "width direction," and the direction in which the shorter side extends will be referred to as the "depth direction." With regard to the depth direction, the side facing the tabletop 11 of another tabletop-equipped fixture 10 will be referred to as the "rear side," and the opposite side will be referred to as the "front side." In addition, below, the vertical direction will be referred to as the "up-down direction."

[0034] The support structures 12 are respectively arranged at two positions below the tabletop 11, spaced apart in the width direction. Each support structure 12 includes a lower support 15 extending in the depth direction and having its underside grounded to the floor F via a pair of adjusters 14, an upper support 16 similarly extending in the depth direction and having its upper surface joined to the underside of the tabletop 11, and a pedestal 17 extending in the vertical direction and connecting the lower support 15 and the upper support 16. The pedestal 17 is connected to the lower support 15 and the upper support 16 at approximately the center in the depth direction. The lower support 15 extends along the floor F at a position close to the floor F. The adjusters 14 are respectively provided near both ends of each lower support 15 in the depth direction. Each adjuster 14 has a disk-shaped grounding portion 14a (see FIG. 5) that contacts the floor surface F and a shaft portion 14b (see FIG. 5) that protrudes upward from the grounding portion 14a, and the shaft portion 14b is threadedly engaged with the lower support body 15. The adjuster 14 can adjust the support position height of the lower support body 15 by rotating the shaft portion 14b relative to the lower support body 15.

[0035] 3 is a perspective view of a portion of the tabletop-equipped furniture 10. In FIG. 3, the position restricting member 13 has been removed. As shown in FIG. 3 , the support column 17 of the support structure 12 includes a rectangular cylindrical lower leg 17L whose lower end is connected to the lower support 15, and a similar rectangular cylindrical upper leg 17U whose upper end is connected to the upper support 16. The upper leg 17U is inserted into the lower leg 17L so as to be slidable in the vertical direction. The upper leg 17U is raised and lowered relative to the lower leg 17L by an electric drive unit (not shown). The entire column 17 extends and retracts vertically as the upper leg 17U rises and lowers, thereby raising and lowering the tabletop 11. The height of the tabletop 11 can be controlled by an operation switch 18 located on the front edge of the tabletop 11 in the depth direction. The tabletop-equipped furniture 10 of this embodiment includes an extension / retraction mechanism for adjusting the height of the tabletop, consisting of the lower leg 17L, the upper leg 17U, and the drive unit. However, the fixture 10 with a tabletop may be configured without an extension mechanism for adjusting the height of the tabletop.

[0036] In the following, when distinguishing between the respective fixtures 10 with tabletops, the reference numerals 10A, 10B, 10C, and 10D in Figures 1 and 2 will be used in conjunction with the term "furniture with tabletops." In the furniture system 1 of this embodiment shown in Figures 1 and 2, one pair of furniture with tabletops 10A and 10B arranged opposite each other constitutes furniture unit 1A, and the other pair of furniture with tabletops 10C and 10D arranged opposite each other constitutes furniture unit 1B. The two furniture units 1A and 1B are arranged side by side in the width direction. Specifically, the furniture with tabletops 10A on one side of the furniture unit 1A is arranged with the furniture with tabletops 10C on the other furniture unit 1B, and the furniture with tabletops 10D on the other furniture unit 1B is arranged with the furniture with tabletops 10B on one side of the furniture unit 1A. In the fixture unit 1A, one of the fixtures 10A and 10B with tabletops constitutes the first fixture with tabletops, and the other constitutes the second fixture with tabletops. Similarly, in the fixture unit 1B, one of the fixtures 10C and 10D with tabletops constitutes the first fixture with tabletops, and the other constitutes the second fixture with tabletops.

[0037] The two tabletop-equipped fixtures 10A and 10B of one fixture unit 1A have lower supports 15 (support structures 12) arranged opposite each other in the depth direction, which can be connected to each other by position regulating members 13. In other words, the tabletop-equipped fixtures 10A and 10B arranged opposite each other can be connected to each other by position regulating members 13 at two positions spaced apart in the width direction. Similarly, the two tabletop-equipped fixtures 10C and 10D of the other fixture unit 1B have lower supports 15 (support structures 12) arranged opposite each other in the depth direction, which can be connected to each other by similar position regulating members 13. In this case too, the tabletop-equipped fixtures 10C and 10D arranged opposite each other can be connected to each other by position regulating members 13 at two positions spaced apart in the width direction.

[0038] Each of the tabletops 11, which is rectangular in plan view, has a rear edge 11Eb on the far side in the depth direction, a front edge 11Ef on the near side in the depth direction, a side edge 11Es1 on one side in the width direction, and an opposite side edge 11Es2 on the other side in the width direction. The rear edge 11Eb of each tabletop 11 can be placed close to (including abutting) another installed object, such as another tabletop-equipped furniture, or at a fixed distance (with a fixed gap) from it. Furthermore, the front edge 11Ef of each tabletop 11 can be faced by a user sitting on a chair, etc. One side edge 11Es1 and the other side edge 11Es2 of each tabletop 11 can be placed close to (including abutting) other installed objects such as other tabletop-equipped furniture that are placed adjacently in the width direction, or can be placed at a constant distance (with a constant gap between them).

[0039] Here, with regard to the two tabletops 11 of each furniture unit 1A, 1B, when the direction in which the two tabletops 11 face each other in a plan view (depth direction) is defined as the first direction and the direction perpendicular to the first direction (width direction) is defined as the second direction, each tabletop 11 can be said to have the following first and second edges. (1) First edge An edge that is arranged facing the opposing top plate 11 in the first direction. (2) Second edge The second edge is disposed adjacent to the first edge of each of the two table tops 11 on the same side in the extending direction. In this embodiment, the rear edge 11Eb of each table top 11 constitutes a first edge, and one side edge 11Es1 and the other side edge 11Es2 of each table top 11 constitute second edges, respectively.

[0040] Fig. 4 is a perspective view showing four lower supports 15 of tabletop-equipped fixtures 10A, 10B, 10C, and 10D in the portion where two fixture units 1A and 1B are arranged adjacent to each other, and two position regulating members 13 for regulating the distance between the four tabletops 11 of each fixture. Fig. 5 is a plan view of the two position regulating members 13. Note that in Fig. 5, parts of each fixture that overlap with the two position regulating members 13 in plan view are shown in phantom lines. The position restricting member 13 of this embodiment is formed of a box-shaped member that is thin in the vertical direction and has a substantially rectangular shape in a plan view. Note that the position restricting member 13 does not necessarily have to be box-shaped (hollow), and may be formed of a solid member. The position restricting member 13 is formed of, for example, metal, hard resin, or the like.

[0041] Hereinafter, when distinguishing between the two positioning members 13, the reference numerals 13A and 13B in Figures 4 and 5 will be used in conjunction with the name "furniture with top." Furthermore, for each of the positioning members 13A and 13B, the direction in which the longer side of the rectangular shape extends in a plan view will be referred to as the "longitudinal direction," and the direction in which the shorter side extends will be referred to as the "transverse direction."

[0042] Position regulating members 13A and 13B are connected to the lower supports 15 arranged at the front and rear in the depth direction with their thickness directions facing the vertical direction and their longitudinal directions facing the depth direction of tabletop 11. Specifically, one position regulating member 13A is connected to the lower supports 15 of tabletop-equipped fixture 10A and the lower supports 15 of tabletop-equipped fixture 10B, and the other position regulating member 13B is connected to the lower supports 15 of tabletop-equipped fixture 10C and the lower supports 15 of tabletop-equipped fixture 10D.

[0043] As shown in FIG. 5, each position restricting member 13A, 13B has two notched locking grooves 19 that open toward one side in the short direction. The two locking grooves 19 are provided near the front end and the back end in the depth direction (longitudinal direction). These locking grooves 19 engage with the shafts 14b of the adjusters 14 attached to the lower part of the lower support 15. In this state, the position restricting members 13A, 13B are connected to the corresponding front and rear lower support members 15 by tightening nuts or the like around the shafts 14b. Specifically, the locking groove 19 on the back side in the depth direction is connected to the lower support member 15 of the top-equipped fixture 10B or 10D at the back in the depth direction, and the locking groove 19 on the front side in the depth direction is connected to the lower support member 15 of the top-equipped fixture 10A or 10C at the front in the depth direction. Therefore, the position restriction members 13A and 13B have connecting portions 25 near the front end and near the back end in the depth direction.

[0044] The opening direction of the locking grooves 19 of one position restricting member 13A is opposite to the opening direction of the locking grooves 19 of the other position restricting member 13B. Specifically, each locking groove 19 of one position restricting member 13A opens on the side facing the inside of the table top 11 (the right side in FIG. 5) based on the other side edge 11Es2 of the table top 11 of the connected fixture. In contrast, each locking groove 19 of the other position restricting member 13B opens on the side facing the inside of the table top 11 (the left side in FIG. 5) based on one side edge 11Es1 of the table top of the connected fixture. In addition, the bottoms of the locking grooves 19 formed in each position restricting member 13A, 13B are positioned in a position biased toward the opening side of each locking groove 19 in the short direction of the position restricting members 13A, 13B.

[0045] When one position restricting member 13A is connected to the lower support 15 of the corresponding fixture, the edge opposite to the side where the locking groove 19 is formed (hereinafter, this edge will be referred to as the "protruding end 21p") protrudes outward (to the left in FIG. 5) from the other edge 11Es2 of the top plate 11 of the corresponding fixture. Therefore, when the position restricting member 13A is connected to the lower support 15 of the corresponding fixture and the protruding end 21p is brought into contact with another installed object, the separation distance between the top plate 11 of the corresponding fixture and the installed object is restricted to a fixed distance d2. In this example, the other installed object is a fixture adjacent in the width direction including the other position restricting member 13B, and the separation distance between the top plate 11 of the corresponding fixture and the other position restricting member 13B, which is part of the other installed object, is restricted to a fixed distance d2.

[0046] When the other position restricting member 13B is connected to the lower support 15 of the corresponding fixture, the edge (protruding end 21p) opposite to the side where the locking groove 19 is formed protrudes outward (to the right in FIG. 5 ) from one side edge 11Es1 of the top plate 11 of the corresponding fixture. Therefore, when the position restricting member 13B is connected to the lower support 15 of the corresponding fixture and the protruding end 21p is brought into contact with another installed object, the separation distance between the top plate 11 of the corresponding fixture and the installed object is restricted to a fixed distance d2. In this example, the other installed object is a fixture adjacent in the width direction including the one position restricting member 13A, and the separation distance between the top plate 11 of the corresponding fixture and the one position restricting member 13A, which is part of the other installed object, is restricted to a fixed distance d2.

[0047] When two fixture units 1A and 1B are arranged adjacent to each other in the width direction with position restriction members 13A and 13B connected to the corresponding fixtures, as shown in Figures 1 and 2, protruding end 21p of one position restriction member 13A and protruding end 21p of the other position restriction member 13B can abut against each other in the width direction. In this case, a gap of a certain distance d2 × 2 is secured between the two top plates 11 on one fixture unit 1A side and the two top plates 11 on the other fixture unit 1B side. The protruding end 21p of each of the position restricting members 13A and 13B is formed with a flat contact surface 26 that is perpendicular to the width direction. The position restricting members 13A and 13B restrict the distance between the top plate 11 and the installed object to a fixed distance by contacting the contact surface 26 with the side surface of the installed object.

[0048] On the other hand, if each position control member 13A, 13B is removed from the lower support 15 of the corresponding fixture (or if the position control members 13A, 13B are not attached to the corresponding lower support 15 from the beginning), the gap between the two top plates 11 on one fixture unit 1A side and the two top plates 11 on the other fixture unit 1B side can be eliminated, or the gap can be reduced to less than the fixed distance d2×2.

[0049] Furthermore, the separation distance in the depth direction between the two locking grooves 19 of one position regulating member 13A is set to a distance that restricts the separation distance between the rear and front top plates 11 to a fixed distance d1 when position regulating member 13A is connected to rear top-equipped fixture 10B and front top-equipped fixture 10A. Similarly, the separation distance in the depth direction between the two locking grooves 19 of the other position regulating member 13B is set to a distance that restricts the separation distance between the rear and front top plates 11 to a fixed distance d1 when position regulating member 13B is connected to rear top-equipped fixture 10D and front top-equipped fixture 10C. Therefore, when each position control member 13A, 13B is connected to the lower support body 15 of the front and rear fixtures, the distance between the top plates 11 of the front and rear fixtures becomes a fixed distance d1, and a gap of a fixed distance d1 is secured between the top plates 11 of the front and rear fixtures. As a result, at the facing portions of the four fixtures, continuous gaps are secured between the rear edge 11Eb (first edge) and the one side edge 11Es1 and the other side edge 11Es2 (second edge).

[0050] On the other hand, if the position control members 13A, 13B are removed from the lower supports 15 of the front and rear fixtures (or if the position control members 13 are not attached from the beginning), the gap between the top plates 11 of the front and rear fixtures can be eliminated or the gap can be reduced to less than the fixed distance d1.

[0051] In this embodiment, each position restricting member 13A, 13B has an area extending in the depth direction so as to connect the areas (connecting portion 25) where the two rear and front locking grooves 19 are formed, and this area constitutes a first extending portion 20 that regulates the distance between the rear-side tabletop 11 and the front-side tabletop 11 to a constant value. Furthermore, one position restricting member 13A has a second extending portion 21 as a portion that protrudes from the first extending portion 20 outward beyond the other side edge 11Es2 of the tabletop 11 of the connected fixture. The other position restricting member 13B has a second extending portion 21 as a portion that protrudes from the first extending portion 20 outward beyond one side edge 11Es1 of the tabletop 11 of the connected fixture.

[0052] The protruding end 21p of each second extending portion 21 of the position regulating members 13A, 13B is capable of abutting against another installed object arranged adjacently in the width direction. In this embodiment, the protruding end 21p of each position regulating member 13A, 13B is capable of abutting against the protruding end 21p of the mating position regulating member 13B, 13A connected to an adjacent fixture.

[0053] As shown in Figure 5, the first extension portion 20 of each position control member 13A, 13B, when connected to each of the fixtures at the back and front in the depth direction, can be divided into an area 20Ea that overlaps vertically with the top plate 11 of the fixture at the front, an area 20Eb that overlaps vertically with the top plate 11 of the fixture at the back, and an intermediate area 20Ec that does not overlap with either top plate 11.

[0054] When position restricting members 13A, 13B of this embodiment are considered from the perspective of connecting portion 25 with the fixture on the front side in the depth direction, two regions 20Ec and 20Eb extending further back than the rear edge 11Eb of the top plate 11 of the fixture on the front side constitute first restricting portion 30 that restricts the distance between the first edge of the top plate 11 and the installed object to a fixed distance. When position restricting members 13A, 13B are considered from the perspective of connecting portion 25 with the fixture on the rear side in the depth direction, two regions 20Ec and 20Ea extending further forward than the rear edge 11Eb of the top plate 11 of the fixture on the rear side constitute first restricting portion 30 that restricts the distance between the first edge of the top plate 11 and the installed object to a fixed distance.

[0055] In addition, in this embodiment, the position control members 13A, 13B have a second extension portion 21 connected to the first extension portion 20, which constitutes a second control portion 31 that controls the distance between the second edge of the connected top plate 11 and the installed object to a fixed distance.

[0056] The upper surfaces of the position control members 13A, 13B connected to the front and rear fixtures are flat article placement surfaces 27. When connected to the front and rear fixtures, the article placement surface 27 is a substantially horizontal surface. Wiring devices and the like can be placed on the upper surface of the article placement surface 27. In particular, the two position control members 13A, 13B arranged in the area where the two fixture units 1A, 1B are adjacent can abut each other at their protruding ends 21p to form a square-shaped placement surface with a large area, with the two article placement surfaces 27 combined.

[0057] As shown in Figures 1 and 2, the position restricting member 13, which connects the rear and front fixtures of one fixture unit 1A at one side edge 11Es1, is installed so that the second extension portion 21 (second restricting portion 31) faces inward of the tabletop 11 of the two fixtures relative to the one side edge 11Es1 (second edge) of the tabletop 11. In other words, the position restricting member 13 does not protrude outward from the one side edge 11Es1 of the tabletop 11 of the two fixtures. Therefore, the position restricting member 13 does not obstruct pedestrians walking beside the one side edge 11Es1 of one fixture unit 1A. In this case, it is also possible to position the one side edge 11Es1 of the tabletop 11 close to or in contact with the side of the adjacent fixture.

[0058] Similarly, the position restricting member 13, which connects the depth and front fixtures of the other fixture unit 1B together at the other edge 11Es2, is installed so that the second extension portion 21 (second restricting portion 31) faces inward of the tabletop 11 of the two fixtures relative to the other edge 11Es2 (second edge) of the tabletop 11. In other words, the position restricting member 13 does not protrude outward from the other edge 11Es2 of the tabletop 11 of the two fixtures. Therefore, the position restricting member 13 does not obstruct pedestrians walking beside the other edge 11Es2 of the other fixture unit 1B. In this case, too, it is possible to position the other edge 11Es2 of the tabletop 11 close to or in contact with the side of the adjacent fixture.

[0059] 1 and 2, the position regulating members 13 arranged on both sides of the fixture system 1 in the width direction are arranged so that the second extending portions 21 (second regulating portions 31) face more inward of the top plate 11 than one side edge 11Es1 or the other side edge 11Es2 of the top plate 11 of the two fixtures. However, it is also possible to connect the position regulating members 13 to each fixture so that the second extending portions 21 (second regulating portions 31) face more outward of the top plate 11 than one side edge 11Es1 or the other side edge 11Es2 of the top plate 11 of the two fixtures. In this case, when another installed object is placed adjacent to both sides of the furniture system 1 in the width direction, the protruding end 21p of the second extending portion 21 (second restricting portion 31) of the position restricting member 13 can be brought into contact with the installed object, and the distance between the table top 11 and the installed object can be set to a constant distance d2. This makes it possible to ensure a continuous gap from the rear edge 11Eb of each table top 11 to one side edge 11Es1 and the other side edge 11Es2, even at the ends of the furniture system 1 in the width direction.

[0060] FIG. 6 is a plan view showing a usage mode of the furniture system 1 when the position restricting members 13 are not attached to the furniture of the furniture units 1A and 1B. In this case, since the distance between the tabletops 11 of the fixtures is not restricted to a fixed distance by the position restricting member 13, it becomes possible to arrange the tabletops 11 so that they are in contact with each other or close to each other.

[0061] As described above, fixture 10 with a tabletop of this embodiment is equipped with position restricting member 13 that is detachably attached to support structure 12 (lower support body 15). Position restricting member 13 is equipped with first restricting portion 30 that restricts the distance between the first edge (rear edge 11Eb) of tabletop 11 and the installed object to a fixed distance by being connected to another installed object (another fixture), and second restricting portion 31 that restricts the distance between the second edge (one side edge 11Es1 or the other side edge 11Es2) of tabletop 11 and the installed object to a fixed distance by being abutted against the other installed object.

[0062] To ensure a certain gap between the top plate 11 of the tabletop-equipped fixture 10 and an installed object (another fixture), the position restricting member 13 is attached to the support structure 12 and the first restricting portion 30 of the position restricting member 13 is connected to the installed object (lower support 15 of the other fixture), thereby restricting the distance between the first edge (rear edge 11Eb) of the tabletop 11 and the installed object to a certain distance d1. At this time, the second restricting portion 31 of the position restricting member 13 abuts against the other installed object (the position restricting member 13 on the other fixture side), thereby restricting the distance between the second edge (one side edge 11Es1 or the other side edge 11Es2) of the tabletop 11 and the installed object to a certain distance d2. To eliminate or reduce the gap between the tabletop 11 and the other installed object, the position restricting member 13 is removed from the support structure 12. As a result, the distance between the first edge (rear edge 11Eb) of the tabletop 11 and other installed objects is no longer regulated by the position regulating member 13, and the distance between the second edge (one side edge 11Es1 or the other side edge 11Es2) of the tabletop 11 and other installed objects is also no longer regulated by the position regulating member 13.

[0063] Therefore, when the fixture 10 with a top plate of this embodiment is used, a continuous gap can be secured between the two adjacent edges of the top plate 11 (the rear edge 11Eb and the one side edge 11Es1 or the other side edge 11Es2) and other installed objects by using a single position regulating member 13, and it is also possible to switch between the presence or absence of a gap and the increase or decrease of the gap. Furthermore, when the fixture 10 with a top plate of this embodiment is used, a continuous gap can be secured between the two adjacent edges of the top plate 11 and other installed objects by using a single position regulating member 13, which makes it possible to simplify the work of routing wiring cables and the work of attaching clamp fittings for fixing options without increasing the number of parts.

[0064] In particular, in this embodiment, when the position restricting member 13 restricts the distance between the edge of the tabletop 11 and an adjacent installed object to a fixed distance, the first restricting portion 30 protrudes further outward from the tabletop 11 than the first edge (rear edge 11Eb), and the second restricting portion 31 protrudes further outward from the tabletop 11 than the second edge (one side edge 11Es1 or the other side edge 11Es2). This ensures that a continuous gap is maintained between the adjacent first edge (rear edge 11Eb) and second edge (one side edge 11Es1 or the other side edge 11Es2) of the tabletop 11 of the tabletop-equipped fixture 10 and the other installed object.

[0065] Furthermore, in the fixture 10 with a tabletop of this embodiment, the position regulating member 13 is detachably attached to a lower support 15 that extends along the floor surface F at a position close to the floor surface F. Therefore, by arranging the position regulating member 13 at a sufficiently low position close to the floor surface F, the position regulating member 13 does not occupy the main space below the tabletop 11. Therefore, when this configuration is adopted, the fixture 10 with a tabletop is easy to use.

[0066] Furthermore, in the case of fixture 10 with a top plate of this embodiment, position restriction member 13 has a flat article placement surface 27 on the upper surface of which an article can be placed when connected to lower support body 15. Therefore, article placement surface 27 formed by position restriction member 13 is positioned sufficiently close to floor surface F, which is in close proximity to lower support body 15. Therefore, when this configuration is adopted, it becomes possible to stably place articles such as wiring devices in a low position close to floor surface F below top plate 11, which is likely to become dead space.

[0067] Furthermore, in the tabletop-equipped furniture 10 of this embodiment, the pedestal 17 connected to the upper part of the lower support 15 is equipped with an extension mechanism for adjusting the elevation of the tabletop 11. Therefore, the extension mechanism of the pedestal 17 allows the height of the tabletop 11 to be adjusted to any height, improving the usability of the tabletop-equipped furniture 10 for users. Furthermore, in this configuration, the position restricting member 13 is attached to a portion (lower support 15) that does not move up and down due to the extension and contraction of the pedestal 17, so the height of the position restricting member 13 does not change as the tabletop 11 moves up and down. Therefore, when this configuration is adopted, it is possible to always stably ensure a continuous gap along the two adjacent edges (first edge and second edge) of the tabletop 11. Furthermore, when the tabletop-equipped fixture 10 is installed adjacent to another installed object (for example, another tabletop-equipped fixture) and the tabletop 11 is raised or lowered, if the other installed object has a lateral protrusion such as a tabletop, there is a concern that an item may become pinched between the rising or lowering tabletop 11 and the lateral protrusion. However, the tabletop-equipped fixture 10 of this embodiment uses a position regulating member 13 connected to the lower support 15 rather than the tabletop 11 to ensure a sufficient gap between the rising or lowering tabletop 11 and the lateral protrusion of the other installed object. Therefore, when the tabletop-equipped fixture 10 of this embodiment is used, it is possible to prevent an item from becoming pinched between the tabletop 11 and the other installed object as it rises or falls.

[0068] Furthermore, fixture 10 with a tabletop of this embodiment is provided with connecting portion 25 that is connected to another installed object so that position restricting member 13 restricts the distance between tabletop 11 and the other installed object to a fixed distance d1. Therefore, by connecting connecting portion 25 to the other installed object, position restricting member 13 is less likely to come off the other installed object, making it possible to reliably maintain a fixed gap between the edge of tabletop 11 and the other installed object.

[0069] Furthermore, in fixture 10 with a top plate of this embodiment, position restricting member 13 is provided with abutment surface 26 that abuts against another installed object so as to restrict the separation distance between top plate 11 and the other installed object to a fixed distance d2. Therefore, simply by abutting abutment surface 26 of position restricting member 13 against the other installed object, it is possible to easily ensure a fixed gap between the edge of top plate 11 and the other installed object.

[0070] Furthermore, in the case of the fixture 10 with a top plate of this embodiment, the position restricting member 13 can be attached to the support structure 12 (lower support 15) so that the second restricting portion 31 protrudes inward of the top plate 11 beyond the corresponding second edge (one side edge 11Es1 or the other side edge 11Es2). Therefore, by attaching the position restricting member 13 to the support structure 12 (lower support 15) so that the second restricting portion 31 protrudes inward of the top plate 11 beyond the corresponding second edge (one side edge 11Es1 or the other side edge 11Es2), it is possible to position the second edge of the top plate 11 close to another installed object. In this case, since the second restricting portion 31 protrudes inward of the top plate 11, this protruding portion can also function as a stopper for a cart placed below the top plate 11.

[0071] Furthermore, the furniture units 1A, 1B of this embodiment each include a pair of furniture units 10 with tabletops arranged facing each other in the depth direction, and a position restricting member 13 connecting the two furniture units 10 with tabletops arranged in the depth direction includes a first extending portion 20 that restricts the distance between the two tabletops 11 to a constant value, and a second extending portion 21 that is connected to the first extending portion 20 and protrudes outward from the tabletops 11 beyond the second edge (one side edge 11Es1 or the other side edge 11Es2) of each tabletop 11. The position restricting member 13 is detachably attached to two support structures 12 (lower supports 15) on the rear and front sides, and the protruding end 21p of the second extending portion 21 is capable of abutting against an installed object arranged adjacent to it in the width direction. Therefore, when the furniture units 1A, 1B of this embodiment are adopted, a single position control member 13 makes it possible to ensure a continuous gap between the first edge (rear edge 11Eb) of the two facing tabletops 11 and the second edge (one side edge 11Es1 or the other side edge 11Es2) of each tabletop 11, and also makes it possible to switch between the presence or absence of a gap and the increase or decrease of the gap. In this embodiment, the protruding end 21p of the second extension portion 21 is capable of abutting against an installed object arranged adjacent to it in the width direction, but the protruding end of the second extension portion 21 may also be capable of being connected to an installed object arranged adjacent to it in the width direction by bolting or other means.

[0072] Second Embodiment Fig. 7 is an enlarged perspective view of a portion of the furniture system 101 of this embodiment. Fig. 8 is a plan view of the position restricting member 113 of this embodiment, and Fig. 9 is a plan view of some of the components of the position restricting member 113. Fig. 10 is a perspective view showing one usage form of the furniture system 101 of this embodiment. The fixture system 101 of this embodiment has an overall configuration that is almost the same as that of the first embodiment, but the configuration of the position regulating member 113 is different from that of the first embodiment.

[0073] The position restriction member 113 includes a restriction body part 35 and a fixing part 36 that is assembled to the restriction body part 35. The restriction body part 35 has a base part 37 that is rectangular in plan view and a protruding piece 38 that protrudes from a long side of the base part 37 in a direction perpendicular to that side. The base part 37 is formed into a U-shaped cross section that has upper and lower walls (not shown) that are generally trapezoidal in plan view, and a side wall 37s (see FIG. 7) that connects the upper wall 37u and the lower wall. The protruding piece 38 is connected to the upper wall 37u of the base part 37.

[0074] The protruding piece 38 is formed in a generally trapezoidal shape tapering in the protruding direction in a plan view. More precisely, the shape of the protruding piece 38 is a trapezoid with the sides curved concavely. The protruding end 21p of the protruding piece 38 is bent downward at a generally right angle, and the outer end face of the bent end serves as the abutment surface 26. The upper surfaces of the base portion 37 and the protruding piece 38 are formed by a flat horizontal surface, and serve as the article placement surface 27 on which articles such as wiring components can be placed. In the position restricting member 113 of this embodiment, the base portion 37 constitutes the first extending portion 20, and the protruding piece constitutes the second extending portion .

[0075] 8, locking grooves 19 are formed near both longitudinal ends of the base portion 37 of the regulating main body part 35. The shafts 14b of the adjusters 14 provided on the rear and front fixtures are inserted into and engaged with these locking grooves 19.

[0076] 8 and 9, the fixing part 36 is formed in a rectangular shape in plan view, similar to the base part 37. The fixing part 36 is also formed in a U-shaped cross section, similar to the base part 37, with an upper wall, a lower wall, and a side wall connecting the upper wall and the lower wall. Near both ends in the longitudinal direction of the upper wall of the fixing part 36, there are formed slip-out prevention recesses 39 which, together with the locking grooves 19 on the base part side, form a substantially circular shaft insertion portion.

[0077] The fixing part 36 is inserted into the U-shaped cross section of the regulating main body part 35 after the shafts 14b of the adjusters 14 of the fixtures on the rear and front sides are inserted into the two locking grooves 19 of the regulating main body part 35. At this time, the slip-out prevention recesses 39 of the fixing part 36, together with the locking grooves 19 of the regulating main body part 35, surround the shafts 14b of the corresponding adjusters 14. In this state, the fixing part 36 is fixed to the regulating main body part 35 with screws or the like. As a result, the position restriction member 113 is connected to the fixtures on the rear and front sides in the depth direction.

[0078] In this embodiment, the base portion 37 of the position restricting member 113 can also be divided into an area 20Ea that overlaps in the vertical direction with the top plate 11 of the fixture on the front side, an area 20Eb that overlaps in the vertical direction with the top plate 11 of the fixture on the rear side, and an intermediate area 20Ec that does not overlap with either top plate 11. When the position restricting member 113 is considered from the perspective of the connection portion with the fixture on the front side, the two areas 20Ec and 20Eb that extend further back than the rear edge 11Eb of the top plate 11 of the fixture on the front side constitute the first restricting portion 30. When the position restricting member 113 is considered from the perspective of the connection portion with the fixture on the rear side in the depth direction, the two areas 20Ec and 20Ea that extend further forward than the rear edge 11Eb of the top plate 11 of the fixture on the rear side constitute the first restricting portion 30. In addition, the position restricting member 113 has a protruding piece 38 connected to the base portion 37 which constitutes the second restricting portion 31 .

[0079] In addition, the position control member 113 arranged at the widthwise end of the fixture system 101 is set so that, when both longitudinal ends of the base portion 37 (first extension portion 20) are connected to the fixtures at the rear and front sides, as shown in Figure 10, the protruding piece 38 (second extension portion 21) faces more inward than the other side edge 11Es2 (or one side edge 11Es1) of the tabletop 11. In this embodiment, the protruding piece 38 that faces inward of the tabletop 11 relative to the other side edge 11Es2 (or one side edge 11Es1) of the tabletop 11 is narrower in width in the depth direction and has an arc-shaped side surface facing the depth direction, so that it functions effectively as a stopper to stop the movement of the cart 40 when the cart 40 is moved from the front side to the back side below the tabletop 11.

[0080] The fixture 10 with a top plate and the fixture unit of this embodiment described above have the same basic configuration as those of the first embodiment, and therefore can achieve the same effects as those of the first embodiment described above.

[0081] Third Embodiment FIG. 11 is a plan view of a furniture unit 201 of this embodiment, and FIG. 12 is a plan view showing a usage mode of the furniture unit 201 that is different from the usage mode shown in FIG. The furniture unit 201 of this embodiment includes a furniture unit 210 with a tabletop and a partition 50, which is another installed object. The furniture unit 210 with a tabletop includes a tabletop 11, a support structure 12 that supports the tabletop 11 from below, and a positioning member 213 that can regulate the horizontal distance between the tabletop 11 and the partition 50 to a fixed distance. The tabletop 11, like that of the first embodiment, has a rear edge 11Eb, a front edge 11Ef, one side edge 11Es1, and an other side edge 11Es2. The support structure 12 includes a lower support 15 that is grounded to the floor surface via an adjuster.

[0082] The partition 50 is formed in a substantially L-shape in a plan view. The partition 50 includes a front wall 50f arranged to face the rear edge 11Eb of the tabletop 11, and a side wall 50s arranged to face one side edge 11Es1 of the tabletop 11.

[0083] The position restricting member 213 of the furniture 210 with a tabletop is formed by a box-shaped block that is rectangular in plan view. The position restricting member 213 is detachably attached to the rear side in the depth direction of the lower support 15 at the lower end of the support structure 12. When attached to the lower support 15, the position restricting member 213 includes a first extending portion 20 that extends along the depth direction of the tabletop 11, and a second extending portion 21 that is connected to the first extending portion 20 and extends from the first extending portion 20 toward one side in the width direction.

[0084] When the position restricting member 213 disposed on the right side in FIG. 11 is connected to the right lower support body 15, the first extending portion 20 protrudes outward (toward the rear) of the table top 11 beyond the rear edge 11Eb of the table top 11. An abutting surface 26a is formed at the protruding end of the first extending portion 20 so as to be able to abut against the side surface (the surface facing the front in the depth direction) of the front wall 50f of the partition 50. When the position restricting member 213 on the right side is connected to the right lower support body 15, the second extending portion 21 protrudes outward (to the right in the figure) of the table top 11 beyond one side edge 11Es1 of the table top 11. An abutting surface 26b is formed at the protruding end of the second extending portion 21 so as to be able to abut against the side surface (the surface facing the table top 11 in the width direction) of the side wall 50s of the partition 50.

[0085] 11 has a first extension portion 20 and a second extension portion 21, similar to the one on the right, but is connected to the lower support body 15 in a different manner than the one on the right. The left position restricting member 213 is connected to the left lower support body 15 so that the second extension portion 21 does not protrude beyond the other side edge 11Es2 of the top plate 11 to the outside of the top plate 11. More specifically, the left position restricting member 213 has the second extension portion 21 protruding in a direction facing inward of the top plate 11 based on the other side edge 11Es2 of the top plate 11.

[0086] In this embodiment, the first extending portion 20 constitutes a first restricting portion 30 that restricts the distance between the first edge (rear edge 11Eb) of the tabletop 11 and the installed object to a fixed distance by abutting against the installed object (partition 50). Also, the second extending portion 21 constitutes a second restricting portion 31 that restricts the distance between the second edge (one side edge 11Es1) of the tabletop 11 and the installed object to a fixed distance by abutting against the installed object (partition 50).

[0087] When the tabletop-equipped fixture 210 is installed so that a continuous gap is formed between it and the partition 50, position restriction members 213 are attached to the left and right lower supports 15, respectively, as shown in Figure 11. When the tabletop-equipped fixture 210 is brought close to the front wall 50f and side wall 50s of the partition 50 in this state, the protruding ends (abutment surfaces 26a) of the first extension portions 20 of the left and right position restriction members 213 abut against the front wall 50f. At this time, the protruding end (abutment surface 26b) of the second extension portion 21 of the right position restriction member 213 abuts against the side wall 50s. As a result, a continuous gap is formed between the top 11 of the tabletop fixture 210 and the partition 50 along the first edge (rear edge 11Eb) and second edge (one side edge 11Es1) of the top 11.

[0088] Furthermore, when the fixture 210 with a tabletop is to be installed without a gap between it and the partition 50 (or by reducing the gap), the position restriction members 213 are removed from the left and right lower supports 15, as shown in Figure 12. When the fixture 210 with a tabletop is brought close to the front wall 50f and side wall 50s of the partition 50 in this state, the rear edge 11Eb and one side edge 11Es1 of the tabletop 11 come into contact with or close to the front wall 50f and side wall 50s of the partition 50, respectively. As a result, the continuous gap along the first edge (rear edge 11Eb) and the second edge (one side edge 11Es1) between the top plate 11 and the partition 50 disappears or is reduced.

[0089] Therefore, when the fixture with a tabletop 210 of this embodiment is adopted, a single position control member 213 (the right-side position control member 213) can ensure a continuous gap between the two adjacent edges of the tabletop 11 and other installed objects, and it is possible to switch between having or not having a gap and increasing or decreasing the size of the gap.

[0090] In the description of this embodiment, the case where the fixture with a top 210 is placed adjacent to the partition 50 has been described, but the other installed object placed adjacent to the fixture with a top 210 is not limited to the partition 50. The other installed object placed adjacent to the fixture with a top 210 may be another fixture with a top, or a pillar or wall of the facility. If the other installed object is a fixture with a tabletop, for example, the position control members (first control parts or second control parts) attached to the lower supports of each fixture with a tabletop may be made to abut against each other.

[0091] <Fourth embodiment> FIG. 13 is an enlarged plan view of a portion of the furniture 310 with a top panel according to this embodiment. The basic configuration of the tabletop-equipped fixture 310 of this embodiment is similar to that of the third embodiment. In the third embodiment, the position regulating member 213 is detachably attached to the lower support 15, whereas the position regulating member 313 of this embodiment is attached to the lower support 15 so that the positions of the first regulating portion 30 and the second regulating portion 31 can be adjusted.

[0092] The position restricting member 313 is rotatably supported, for example, by the shaft portion 14b of an adjuster attached to the lower support body 15. The position restricting member 313 is rotatable between a retracted position where the entire position restricting member 313 is positioned below the top plate 11, and a restricting position where parts of the first restricting portion 30 (first extending portion 20) and the second restricting portion 31 (second extending portion) protrude outward from the top plate 11. A rotation stopper (not shown) is provided between the position restricting member 313 and the lower support body 15. The rotation stopper can fix the position restricting member 313 in a state where it is in the retracted position and a state where it is in the protruding position.

[0093] In this embodiment, as in the third embodiment, a single position control member 313 can ensure a continuous gap between the two adjacent edges of the tabletop 11 and other installed objects, and can also switch between having or not having a gap and increasing or decreasing the size of the gap. Furthermore, in the fixture 310 with a top plate of this embodiment, even when the position control member 313 is not used, there is no need to remove the position control member 313 from the lower support body 15, which eliminates the need for the complicated work of removing parts and also eliminates the need to store the removed parts.

[0094] 13, the position restricting member 313 is rotatably attached to the lower support 15, and the position of the position restricting member 313 is adjustable between a retracted position and a restricting position. However, the method of attaching the position restricting member 313 to the lower support 15 while allowing the positions of the first restricting portion 30 and the second restricting portion 31 to be adjustable is not limited to this. The position restricting member 313 may be structured so as to be able to slide linearly from the inside of the lower support 15 toward the outer corner portion of the lower support 15.

[0095] The present invention is not limited to the above-described embodiment, and various design modifications are possible without departing from the spirit of the present invention. For example, in the above-described embodiment, a top plate having a rectangular shape in a plan view is used, but the shape of the top plate is not necessarily limited to a shape having right-angled corners. For example, the corners of the top plate may be rounded or may have short chamfered portions.

[0096] In addition, in the above embodiment, the position regulating members 13, 213, 313 are attached to the lower support 15 extending along the floor surface, but the attachment positions of the position regulating members 13, 213, 313 are not limited to this. The position regulating members 13, 213, 313 may be attached to any part of the support structure 12 disposed below the top plate 11. [Explanation of symbols]
