Description

[Technical Field]

[0001] The present invention relates to a fixture with a top. [Background technology]

[0002] Various facilities, such as offices and public facilities, are equipped with furniture with tabletops to provide users with work surfaces. One such furniture with tabletops is disclosed in which a support column extending in the vertical direction, a tabletop supported in a cantilevered manner on the upper end of the support column, and legs extending from the lower end of the support column along the installation surface while facing the tabletop and contacting the installation surface via casters (see, for example, Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5479952 Summary of the Invention [Problem to be solved by the invention]

[0004] In a configuration in which the tabletop is supported by a cantilever on a support column, as in the above-mentioned tabletop-equipped furniture, a load acting downward on the free end of the tabletop acts to pull up the connecting portion of the leg with the support column. In the prior art, the casters are placed in contact with the ground at a position distant from the support column in the horizontal direction, so there is still room for improvement in terms of stable installation of tabletop-equipped furniture, especially for tabletops with large or heavy tabletops.

[0005] To provide a fixture with a top that can be stably installed even if the top is large or heavy. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. (1) A fixture with a top according to one aspect of the present invention comprises a support structure and a top that is formed in two directions intersecting the vertical direction, with a first direction being the longitudinal direction and a second direction being the lateral direction, and is supported from below by the support structure, wherein the support structure comprises a base leg having a first base portion extending in the first direction and a second base portion extending from a first side end of the first base portion in the first direction to a first side in the second direction, and a second base portion extending from the first side end of the first base portion in the first direction to a first side in the second direction, and a support structure having a support leg having a second base portion extending from the first side end of the first base portion in the first direction to a first side in the second direction. and a support portion extending upward from a corner portion where the corner portion is located and supporting a first side end of the top plate in the first direction, and the base leg comprises a first grounding portion provided in a portion of the first base portion located on the second side in the first direction from the corner portion and in contact with the installation surface, a second grounding portion provided in a portion of the second base portion located on the first side in the second direction from the corner portion and in contact with the installation surface, and a corner grounding portion provided in the corner portion and in contact with the installation surface.

[0007] According to this aspect, the corner portion where the support column is provided contacts the installation surface via the corner contact portion. As a result, the load of the tabletop transmitted to the base leg via the support column is supported on the installation surface via the corner contact portion. This allows the base leg to resist a load acting in a direction that pulls up the base leg on the connecting portion with the support column, compared to when the base leg contacts the installation surface only via the first contact portion or the second contact portion. Furthermore, since the base leg is grounded on the installation surface via the first grounding portion provided on the first base portion, even if a large load acts on the connecting portion of the base leg with the support portion in a direction that pulls the base leg up, due to the top plate being supported in a cantilevered manner, the first base portion can easily exert resistance to the load. In addition, since the base legs are grounded on the installation surface via the second grounding portion provided on the second base portion, rattling of the tabletop-equipped fixture in the twisting direction of the tabletop can be suppressed. As a result, even fixtures with large or heavy tabletops can be installed stably.

[0008] (2) In the fixture with a top plate according to the aspect (1) above, it is preferable that the first grounding portion is provided on at least a second side end portion of the first base portion in the first direction. According to this aspect, the base leg can easily withstand a load acting in a direction that pulls up the base leg on the connecting portion with the support post, thereby enabling the tabletop-equipped furniture to be installed stably.

[0009] (3) In the fixture with a top plate according to the above aspect (1) or (2), it is preferable that the first base portion comprises an internal frame in which the first grounding portion is provided, and a frame cover that covers the internal frame from above and is fixed to the internal frame. According to this aspect, the aesthetic appearance of the first base portion can be improved by covering the inner frame with the frame cover. Moreover, since the frame cover is fixed to the inner frame, it is easy to ensure the bending rigidity of the first base portion.

[0010] (4) In the fixture with a top according to the aspect (3) above, it is preferable that the internal frame is formed in a square cylindrical shape. According to this aspect, it is easy to ensure the bending rigidity of the first base portion, and therefore it is easy to make the first base portion exert resistance to the load of the top plate.

[0011] (5) In the fixture with a top plate according to any one of the above aspects (1) to (4), it is preferable that the second grounding portion is provided at least at a first side end portion of the second base portion in the second direction. According to this aspect, it is easy to suppress rattling of the fixture with a tabletop in the twisting direction of the tabletop.

[0012] (6) In the fixture with a top plate according to any one of the above aspects (1) to (5), it is preferable that a storage fixture capable of storing items is disposed on the second base portion. According to this aspect, the base leg can more easily resist a load acting in a direction that pulls up the base leg on the connecting portion with the support portion.

[0013] (7) In the fixture with a top plate according to any one of the above aspects (1) to (6), the second base portion is preferably formed in a rectangular cylindrical shape. According to this aspect, it is easy to ensure the bending rigidity of the second base portion, and therefore it is easy to make the second base portion exert resistance to the load of the top plate. [Effects of the Invention]

[0014] According to each of the above aspects, even a large or heavy top plate can be stably installed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0016] Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, corresponding components may be designated by the same reference numerals, and a description thereof may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," not only strictly refer to such arrangements, but also refer to a state in which there is a relative displacement with an angle or distance to the extent that tolerances or the same function are obtained. In this embodiment, "facing" does not only refer to a case in which the orthogonal directions (normal directions) of two surfaces are aligned with each other, but also includes a case in which the orthogonal directions intersect with each other.

[0017] [Fixture with tabletop 1] FIG. 1 is a perspective view of a tabletop-equipped fixture 1 seen from above. The tabletop-equipped fixture 1 shown in Figure 1 is installed on an installation surface F in various facilities. The tabletop-equipped fixture 1 includes a desk fixture 10 and a storage fixture 11. In the following explanation, the direction perpendicular to the installation surface F is referred to as the up-down direction, and the two directions perpendicular to the up-down direction are referred to as the left-right direction and the front-to-back direction. In this case, the arrow FR indicates the forward direction, and the arrow LH indicates the left side (the left side as seen from the user of the sub-function described below).

[0018] <Desk furniture 10> The desk fixture 10 includes a top plate 21 and a support structure 22.

[0019] <Tabletop 21> The tabletop 21 is formed in a rectangular shape with the left-right direction as the longitudinal direction and the front-to-rear direction as the short side when viewed from the top-down direction (plan view). The tabletop 21 of this embodiment is a relatively large tabletop with a left-to-right dimension of, for example, 180 cm to 210 cm. The tabletop 21 can be used by, for example, multiple users facing each other in the front-to-rear direction with the tabletop 21 in between. In this case, the tabletop 21 can be used with a main user (e.g., a daily user) positioned in front of the tabletop 21 and a secondary user (e.g., a visitor) positioned behind the tabletop 21. The upper surface of the tabletop 21 forms a smooth work surface. The tabletop 21 may be usable only from either the front-to-rear direction or from the left-to-right direction.

[0020] The table top 21 has a dimension in the front-to-rear direction that increases toward a first side (left side) in the left-to-right direction. Specifically, the entire front edge of the table top 21 extends linearly in the left-to-right direction, and the rear edge extends while curving forward toward a second side (right side) in the left-to-right direction. That is, in a plan view, the table top 21 is formed in an asymmetric shape with respect to an imaginary line L that passes through the center of the left edge in the front-to-rear direction. However, the table top 21 may also be formed in a symmetric shape with respect to the imaginary line L. Furthermore, the table top 21 may have a shape other than a rectangular shape, such as an oval, as long as the shape has the left-to-right direction as the longitudinal direction and the front-to-rear direction as the lateral direction.

[0021] <Support structure 22> Fig. 2 is a bottom view of the tabletop-equipped furniture 1. Fig. 3 is a perspective view of the support structure 22 as seen from above. Fig. 4 is an exploded perspective view of the support structure 22. 2 to 4, the support structure 22 supports the top plate 21 from below. The support structure 22 includes base legs 25, support columns 26, and auxiliary columns 27.

[0022] The base leg 25 is disposed along the installation surface F, and functions as a base for the support structure 22. The base leg 25 is formed in an L-shape in a plan view. The base leg 25 includes a first base portion 31, a second base portion 32, and a pedestal portion 33. 2 and 4, the first base portion 31 is formed in a rectangular shape with the longitudinal direction being the left-right direction and the lateral direction being the short side direction in a plan view. The first base portion 31 includes an internal frame 41 and a frame cover 42.

[0023] FIG. 5 is a cross-sectional view taken along line VV in FIG. As shown in FIGS. 2 to 5 , the internal frame 41 is formed in a ladder shape with the left-right direction as the long side and the front-rear direction as the short side by combining multiple rectangular tubular members with the up-down direction as the long side, out of the two directions intersecting the extension direction. In the illustrated example, the length of the internal frame 41 in the left-right direction is shorter than the length of the tabletop 21 in the left-right direction, and the length in the front-rear direction is shorter than the length of the tabletop 21 in the front-rear direction. Therefore, the entire internal frame 41 overlaps the tabletop 21 in a plan view. The rectangular tubular members constituting the internal frame 41 are formed by bending a plate material thinner than the vertical height of the first base portion 31 by press processing or the like, and then fixing the opposing edges together by welding or the like. In other words, the rectangular tubular members constituting the internal frame 41 are formed hollow.

[0024] The rectangular tubular members that make up the internal frame 41 include first left and right frames 44 a, 44 b, side frames 45 , first front and rear frames 46 , a partition frame 47 , end frames 48 , and a connecting frame 49 . The first left and right frames 44 are provided as a pair spaced apart in the front-rear direction. The first left and right frames 44 extend parallel to each other in the left-right direction while facing each other in the front-rear direction. As shown in Fig. 2, the side frame 45 is disposed rearward of the rear first left / right frame 44b of the first left / right frames 44a, 44b. The side frame 45 extends parallel to the first left / right frame 44b, facing the left end of the first left / right frame 44b in the front-rear direction. In the illustrated example, a portion of the side frame 45 protrudes to the left of the first left / right frame 44b. Note that the distance in the front-rear direction between the first left / right frame 44b and the side frame 45 is shorter than the distance in the front-rear direction between the first left / right frames 44a, 44b.

[0025] As shown in Figures 2 and 4, the first front-rear frame 46 connects the portions of the first left-right frames 44a, 44b that protrude further to the right than the side frame 45. In this embodiment, a plurality of first front-rear frames 46 are provided at intervals in the left-right direction. The first front-rear frames 46 extend parallel to each other in the front-rear direction. Both front and rear ends of each first front-rear frame 46 are fixed to the corresponding first left-right frame 44a, 44b by welding or the like.

[0026] The compartment frame 47 connects the first left and right frames 44a, 44b at their portions that overlap with the side frames 45 when viewed from the front-to-rear direction. A pair of compartment frames 47 are provided with a gap in the left-to-right direction. Like the first front-to-rear frames 46, each compartment frame 47 extends linearly in the front-to-rear direction. Both front and rear ends of each compartment frame 47 are fixed to the corresponding first left and right frames 44a, 44b by welding or the like. The space surrounded by the first left and right frames 44a, 44b and the compartment frame 47 forms a base accommodating section 50 that is rectangular in plan view.

[0027] The end frame 48 connects the left ends of the first left and right frames 44a, 44b and the side frames 45. The end frame 48 extends parallel to the partition frame 47. The end frame 48 is fixed to the first left and right frames 44a, 44b and the side frames 45 by welding or the like.

[0028] The lower surface of each of the frames 44 to 48 of the internal frame 41 is in direct contact with the installation surface F. In this case, it is preferable that the entire lower surface of the internal frame 41 is in direct contact with the installation surface F. However, the internal frame 41 may also be in contact with the installation surface F via a non-rolling contact portion such as an adjuster.

[0029] The frame cover 42 conceals the internal frame 41 so that it cannot be seen from the outside. The frame cover 42 is formed by bending a thin plate material thinner than the vertical height of the first base portion 31 through press processing or the like. The frame cover 42 is formed in a hollow box shape that opens downward, thereby covering the internal frame 41 from above and the sides. The frame cover 42 is formed in a shape similar to the top plate 21 in a scaled-down planar view. Specifically, the entire front edge of the frame cover 42 extends linearly in the left-right direction, while the rear edge extends while curving forward as it moves toward the right. Therefore, the distance from the imaginary line L to the front edge of the frame cover 42 is uniform throughout the entire length in the left-right direction. In this case, as shown in FIG. 4 , the distance from the imaginary line L to the front edge D1 of the frame cover 42 is shorter than the maximum distance (the distance at the left end) from the imaginary line L to the rear edge D2 of the frame cover 42. In the illustrated example, the distance from the imaginary line L to the front edge of the frame cover 42 is equal to the minimum distance D3 (the distance at the right end) from the imaginary line L to the rear edge.

[0030] As shown in FIGS. 3 and 4, the frame cover 42 includes an upper plate portion 42a and a side plate portion 42b. The upper plate portion 42a overlaps with at least a portion of the internal frame 41 that avoids the base accommodating portion 50 in a plan view. The portion of the upper plate portion 42a that overlaps with the internal frame 41 in a plan view is fixed to the internal frame 41 by welding or the like. Therefore, the frame cover 42, together with the internal frame 41, constitutes a strength member. A recess 42c that is open forward and in the vertical direction is formed in the portion of the upper plate portion 42a that overlaps with at least the base accommodating portion 50 in a plan view. In other words, the left end portion of the first left / right frame 44a and the base accommodating portion 50 are exposed upward through the recess 42c.

[0031] The side plate portion 42b is continuous with the outer peripheral edge of the upper plate portion 42a. The side plate portion 42b extends downward from the upper plate portion 42a to surround the periphery of the inner frame 41. The side plate portion 42b includes a front wall portion 42b1, a rear wall portion 42b2, and a right wall portion 42b3.

[0032] 5, the front wall portion 42b1 is continuous with the front edge of the upper plate portion 42a. The front wall portion 42b1 slopes downward as it extends forward. The front edge of the front wall portion 42b1 forms the front edge of the frame cover 42. The front edge of the front wall portion 42b1 is in contact with the installation surface F. The rear wall portion 42b2 is continuous with the rear edge of the upper plate portion 42a. The rear wall portion 42b2 slopes downward as it extends rearward. The rear edge of the rear wall portion 42b2 forms the rear edge of the frame cover 42. The rear edge of the rear wall portion 42b2 is in contact with the installation surface F. As shown in Figures 3 and 4, the right wall portion 42b3 is continuous with the left edge of the upper plate portion 42a and spans the front wall portion 42b1 and the rear wall portion 42b2 in the front-to-rear direction. The right wall portion 42b3 slopes downward as it moves leftward. The right edge of the right wall portion 42b3 is in contact with the installation surface F. A gap may be provided between the outer periphery of the side plate portion 42b and the floor surface F to prevent the insertion of a front sheet or the like. The side plate portion 42b may also extend perpendicular to the installation surface F.

[0033] The second base portion 32 extends forward from the left end portion of the first base portion 31. The second base portion 32 includes a frame main body 51 and a frame connecting portion 52. The frame main body 51 is formed in a ladder shape with the front-rear direction as its longitudinal direction and the left-right direction as its short side by combining rectangular tube members with the left-right direction as its longitudinal direction, of the two directions intersecting the extension direction. In a plan view, the frame main body 51 protrudes forward relative to the top plate 21. Note that the rectangular tube members constituting the frame main body 51 are formed, for example, by bending a thin plate material thinner than the vertical height of the second base portion 32 by press processing or the like, and then fixing the opposing edges together by welding or the like. In other words, the rectangular tube members constituting the frame main body 51 are hollow. In this embodiment, the vertical height of the frame main body 51 is lower than the vertical height of the internal frame 41. However, the heights of the frame main body 51 and the internal frame 41 can be changed as appropriate.

[0034] The frame body 51 includes a second front-rear frame 53 and a second left-right frame 54 . The second front-rear frames 53 are provided as a pair with a gap in the left-right direction. The second front-rear frames 53 extend parallel to each other in the front-rear direction while facing each other in the left-right direction. The second left-right frame 54 spans the second front-rear frames 53 in the front-rear direction. In this embodiment, a plurality of second left-right frames 54 are provided at intervals in the front-rear direction. The second left-right frames 54 extend parallel to each other in the left-right direction. Both left and right ends of each second left-right frame 54 are fixed to the corresponding second front-rear frame 53 by welding or the like.

[0035] The lower surfaces of the frames 53 and 54 of the frame main body 51 are in direct contact with the installation surface F. In this case, it is preferable that the entire lower surface of the frame main body 51 is in direct contact with the installation surface F. However, the frame main body 51 may also be in contact with the installation surface F via a non-rolling contact portion such as an adjuster.

[0036] The frame connecting portion 52 connects the inner frame 41 and the frame main body 51. The frame connecting portion 52 is formed by bending a metal or other plate material into a crank shape. The front end of the frame connecting portion 52 overlaps from above with the second left / right frame 54a, which is the rearmost of the second left / right frames 54. The front end of the frame connecting portion 52 is fastened to the second left / right frame 54a with screws or the like. The rear end of the frame connecting portion 52 overlaps from above with the left end of the first left / right frame 44a (the portion exposed through the recess 42c). The rear end of the frame connecting portion 52 is fastened to the left end of the first left / right frame 44a with screws or the like.

[0037] FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. As shown in FIGS. 4 and 6 , the base 33 is formed into a box shape that opens downward by pressing a metal or other plate material. The base 33 is fitted into the base accommodating portion 50. Specifically, the upper wall 33a of the base 33 has the same external shape as the base accommodating portion 50 in a plan view. The upper wall 33a is exposed upward through the upper end opening of the base accommodating portion 50. The side walls 33b of the base 33 are bent downward from each edge of the upper wall 33a. The side walls 33b are fixed by welding or the like to the surfaces of the first left and right frames 44a, 44b and the partition frame 47 that define the base accommodating portion 50. The lower edges of the side walls 33b are close to or abut against the installation surface F.

[0038] 2, the left end portion of the first base portion 31 constitutes a corner portion 60 of the base leg 25 in a plan view. That is, the corner portion 60 is a portion of the first base portion 31 that overlaps with the second base portion 32 when viewed from the front-to-rear direction, and includes a portion to which the second base portion 32 is connected via the frame connecting portion 52.

[0039] Of the contact portions of the first base portion 31 with the installation surface F, the portion located to the right of the corner portion 60 constitutes the first contact portion 61 in this embodiment. Specifically, the first contact portion 61 is the portion of the lower surface of the inner frame 41 and the lower edge of the frame cover 42 located to the right of the corner portion 60. The portion of the second base portion 32 that comes into contact with the installation surface F (the portion of the base leg 25 that is located forward of the corner portion 60) constitutes the second grounding portion 62 in this embodiment. Specifically, the second grounding portion 62 is the lower surface of the frame main body 51.

[0040] Of the contact portions of the first base portion 31 with the installation surface F, the portions located at the corner portions 60 constitute corner contact portions 63 in this embodiment. The corner contact portions 63 are portions of the contact portions of the first base portion 31 with the installation surface F other than the first contact portions 61, and are portions of the lower surface of the inner frame 41 and the lower edge of the frame cover 42 located at the corner portions 60. In this embodiment, the base leg 25 is formed in an L-shape in plan view, and grounding portions are provided on each side and on the corner portion 60. Specifically, the base leg 25 has a corner grounding portion 63 provided on the corner portion 60, a first grounding portion 61 provided on a portion located to the right of the corner portion 60, and a second grounding portion 62 provided on a portion located in front of the corner portion 60.

[0041] 3 and 4, the support column 26 extends upward from the base 33 and supports the top panel 21 so that the top panel 21 can be raised and lowered. The support column 26 includes a lower flange 26a, a lifting unit 26b, and an upper flange 26c. The lower flange portion 26a is a plate material having a rectangular shape in a plan view. The lower flange portion 26a is superimposed on the upper wall 33a from above. The lower flange portion 26a is fastened to the upper wall 33a with screws or the like. In other words, the support portion 26 is supported on the installation surface F via the corner grounding portions 63.

[0042] Lifting unit 26b extends upward from lower flange 26a. Lifting unit 26b has a common vertical axis and is configured with a plurality of legs with different outer shapes in a plan view, nested together. With the bottom end of the leg with the largest outer shape fixed to lower flange 26a, for example, lifting unit 26b expands and contracts in the vertical direction as the plurality of legs move relative to one another in the vertical direction (a so-called telescopic structure).

[0043] The upper flange portion 26c is fixed to the upper end of the leg tube that has the smallest outer diameter among the leg tubes that make up the lifting unit 26b. The upper flange portion 26c is a plate material that is rectangular in plan view, similar to the lower flange portion 26a. The upper flange portion 26c is fixed to the underside of the tabletop 21. That is, the tabletop 21 rises and falls in accordance with the extension and retraction of the lifting unit 26b.

[0044] Here, in the left-right direction, upper flange portion 26c is fixed to an area located on the left side of the center of table top 21. Therefore, table top 21 is supported in a cantilevered manner toward the right from support column 26. In other words, the distance from upper flange portion 26c to the left edge of table top 21 is shorter than the distance from upper flange portion 26c to the right edge of table top 21. Furthermore, in the front-rear direction, upper flange portion 26c is fixed to an area including the center of table top 21.

[0045] 3 and 5, the auxiliary portion 27 supports the support portion 26. The auxiliary portion 27 includes an upright stay 65 and a surrounding stay 66. The upright stay 65 extends vertically along the support column 26 on the left side of the support column 26. The upright stay 65 is formed in a C-shape that opens toward the left side in a plan view. The lower end of the upright stay 65 is fixed by welding or the like to a portion of the inner frame 41 located on the left side of the support column 26 (the first left and right frames 44a, 44b and the end frame 48).

[0046] The surrounding stay 66 protrudes to the right from the upper end of the standing stay 65. In a plan view, the surrounding stay 66 is formed in a C-shape that opens to the left. The surrounding stay 66, together with the standing stay 65, surrounds the periphery of the lifting unit 26b. The surrounding stay 66 is fixed to the leg tube with the largest outer diameter among the leg tubes that make up the lifting unit 26b.

[0047] <Storage fixture 11> 1, the storage fixture 11 has a function of covering a part of the support structure 22 and storing items. The storage fixture 11 includes a housing 80, a partition plate 81, and a closing plate 82. The housing 80 is formed in a box shape that opens to the right, for example, and includes a bottom wall 91, a front wall 92, a rear wall 93, a left wall 94, and a top wall 95. As shown in FIGS. 1, 2, and 6, the bottom wall 91 is formed in a rectangular shape with its longitudinal direction extending in the front-to-rear direction and its transverse direction extending in the left-to-right direction in a plan view. The bottom wall 91 is superimposed on the base legs 25. As shown in FIG. 5, a through-hole 91a is formed in the rear end of the bottom wall 91 at a portion that overlaps with the support column 26 and the auxiliary member 27 in a plan view. With the support column 26 and the auxiliary member 27 passing through the through-hole 91a, the rear end of the bottom wall 91 is superimposed on a portion of the upper surface of the inner frame 41 that is exposed through the recess 42c at the corner portion 60. The rear end of the bottom wall 91 may be fixed to a portion of the inner frame 41 that supports the bottom wall 91 with a screw or the like.

[0048] FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. As shown in FIGS. 2 and 6 , the front portion of the bottom wall 91 is superimposed on the second base portion 32. Therefore, the second base portion 32 is covered from above by the bottom wall 91. The front portion of the bottom wall 91 is fixed to the frame body 51 with screws or the like. An adjuster 98 is provided on the bottom wall 91 at a position that does not overlap with the base leg 25 in a plan view. In other words, the storage fixture 11 is in contact with the installation surface F via the base leg 25 or the adjuster 98. Note that a baseboard member 99 that protrudes downward is provided on, for example, the front end of the bottom wall 91. The baseboard member 99 fills the gap between the underside of the bottom wall 91 and the installation surface F, thereby preventing the adjuster 98 and the second base portion 32 from being exposed. The baseboard member 99 extends along the front edge of the bottom wall 91.

[0049] The front wall 92 extends upward from the front end of the bottom wall 91 . The rear wall 93 extends upward from the rear end of the bottom wall 91 . The left wall 94 extends upward from the left end of the bottom wall 91 and bridges between the front wall 92 and the rear wall 93.

[0050] The top wall 95 faces the bottom wall 91 in the up-down direction. The top wall 95 is supported by a front wall 92, a rear wall 93, and a left wall 94. A through-hole 95a is formed in the top wall 95 at a position that overlaps with the support column 26 in a plan view. The support column 26 protrudes upward beyond the top wall 95 through the through-hole 95a.

[0051] The partition plate 81 is provided in a portion located forward of the support column 26. The partition plate 81 is supported by a bottom wall 91, a left wall 94, and a top wall 95. The partition plate 81 separates the interior of the housing 80 into a space located forward of the support column 26 (item storage space S1) and a portion located rearward of the support column 26 (mechanism storage space S2). Note that the item storage space S1 may be provided with a drawer, a door, or the like.

[0052] The closing plate 82 is supported by the bottom wall 91, the rear wall 93, the top wall 95, and the partition plate 81. The closing plate 82 closes the opening of the mechanism storage space S2 among the openings of the housing 80. As a result, the inside of the mechanism storage space S2 is surrounded by the storage fixtures 11 so that it cannot be seen.

[0053] As described above, the tabletop-equipped fixture 1 of this embodiment includes a support structure 22 and a tabletop 21 that is formed with a longitudinal direction in the left-right direction (first direction) and a lateral direction (second direction) as a lateral direction, of two directions intersecting the vertical direction, and is supported from below by the support structure 22. The support structure 22 includes a base leg 25 that is L-shaped in a plan view, and a support portion 26 that extends upward from a corner portion 60 of the base leg 25 and supports the left end portion (first side end portion in the first direction) of the tabletop 21. The base leg 25 includes a first grounding portion 61 that is provided on the first base portion 31 at a portion located to the right of the corner portion 60 and that comes into contact with the installation surface F, a second grounding portion 62 that is provided on the second base portion 32 at a portion located forward of the corner portion 60 and that comes into contact with the installation surface F, and a corner grounding portion 63 that is provided on the corner portion 60 and that comes into contact with the installation surface F. According to this configuration, the corner portion 60 where the support portion 26 is provided contacts the installation surface F via the corner contact portion 63. As a result, the load of the top plate 21 transmitted to the base leg 25 via the support portion 26 is supported on the installation surface F via the corner contact portion 63. As a result, compared to when the base leg 25 contacts the installation surface F only via the first contact portion 61 or the second contact portion 62, the base leg 25 can resist a load acting in a direction that pulls the base leg 25 up on the connecting portion with the support portion 26. Furthermore, since the base leg 25 is grounded on the installation surface F via the first grounding portion 61 provided on the first base portion 31, even if a large load acts on the connecting portion of the base leg 25 with the support portion 26 in a direction that pulls the base leg 25 up, due to the top plate 21 being supported in a cantilevered manner, the first base portion 31 can easily exert resistance to the load. Furthermore, since the base leg 25 is grounded on the installation surface F via the second grounding portion 62 provided on the second base portion 32, rattling of the tabletop-equipped fixture 1 in the twisting direction of the tabletop 21 can be suppressed. As a result, even a fixture 1 with a large or heavy top plate 21 can be installed stably.

[0054] In the tabletop-equipped furniture 1 of this embodiment, the first grounding portion 61 is configured to be provided at least on the right end portion (second side end portion in the first direction) of the first base portion 31. This configuration makes it easier for the base leg 25 to resist a load acting in a direction that pulls up the base leg 25 on the portion of the base leg 25 that connects to the support portion 26. Therefore, the tabletop-equipped furniture 1 can be installed stably.

[0055] In the fixture 1 with a top plate of this embodiment, the first base portion 31 is configured to include an internal frame 41 provided with a first grounding portion 61, and a frame cover 42 that covers the internal frame 41 from above and is fixed to the internal frame 41. According to this configuration, the inner frame 41 is covered with the frame cover 42, thereby improving the aesthetic appearance of the first base portion 31. Furthermore, since the frame cover 42 is fixed to the inner frame 41, it is easy to ensure the bending rigidity of the first base portion 31.

[0056] In the furniture unit 1 with a top plate of this embodiment, the first base portion 31 is configured to be formed in a square cylindrical shape. According to this configuration, it is easy to ensure the bending rigidity of the first base portion 31, and therefore it is easy for the first base portion 31 to exert resistance to the load of the top plate 21.

[0057] In the tabletop-equipped furniture 1 of this embodiment, the second ground contact portion 62 is provided at least at the front end portion (first side end portion in the second direction) of the second base portion 32. This configuration makes it easier to suppress rattles of the tabletop-equipped furniture 1 in the twisting direction of the tabletop 21.

[0058] In the fixture with a top panel 1 of this embodiment, a storage fixture 11 capable of storing articles is arranged on the second base portion 32. According to this configuration, the portion of the base leg 25 that is connected to the support portion 26 can more easily resist a load that acts in a direction that pulls the base leg 25 up.

[0059] In the tabletop-equipped furniture 1 of this embodiment, the second base portion 32 is configured to be formed in a square cylindrical shape. According to this configuration, it is easy to ensure the bending rigidity of the second base portion 32, and therefore it is easy to make the second base portion 32 exert resistance to the load of the top plate 21.

[0060] (Other variations) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the appended claims. In the above-described embodiment, the support column 26 is configured to extend and retract in the vertical direction, thereby allowing the tabletop 21 to move up and down, but the present invention is not limited to this configuration. The height of the tabletop 21 in the vertical direction may be fixed.

[0061] In the above-described embodiment, an example was described in which the desk fixture 10 and the storage fixture 11 are combined as the tabletop-equipped fixture 1, but the storage fixture 11 is not an essential component. Furthermore, the fixtures combined with the desk fixture 10 may be chairs such as benches, sinks, lighting equipment, monitor stands, etc., in addition to the storage fixture 11. Furthermore, the fixture with a top 1 is not limited to the desk fixture 10, but may be any other fixture with a top, such as a shelf or a cart device. In the above-described embodiment, a configuration including the base leg 25 that is L-shaped in plan view has been described, but the configuration is not limited to this.

[0062] In the above-described embodiment, the case has been described in which the inner frame 41 constituting the first ground contact portion 61 of the first base 31 integrally forms the corner portion 60, but this configuration is not limited thereto. The first ground contact portion 61 and the corner portion 60 (corner ground contact portion 63) may be formed of separate members. Also, even when the corner portion 60 is formed by the rear end portion of the second base portion 32, the corner portion 60 (corner ground contact portion 63) may be formed of a separate member from the frame main body 51 constituting the second ground contact portion 62. In the above-described embodiment, a configuration has been described in which fixtures such as storage fixture 11 are arranged separately from second base portion 32, but this configuration is not limited to this. For example, frame body 51 of second base 32 may be omitted, and bottom wall 91 of storage fixture 11 itself may function as second base 32. Even in this case, various fixtures other than storage fixture 11 may be used as fixtures that function as second base 32.

[0063] In the above-described embodiment, the first base portion 31 has been described as having a configuration in which the entire lower surface of the inner frame 41 is in contact with the installation surface F, but the present invention is not limited to this configuration. The first base portion 31 may also be configured to be in contact with the installation surface F intermittently. In the above-described embodiment, the inner frame 41 and the frame cover 42 constituting the first base portion 31 are both configured to be hollow and formed by bending a plate material, but the present invention is not limited to this configuration. The first base portion 31 may also be formed to be solid. In the above-described embodiment, the first base portion 31 is configured to include the inner frame 41 and the frame cover 42, but is not limited to this configuration. The first base portion 31 may be configured to include, for example, one of the inner frame 41 and the frame cover 42.
