[0003] [Patent Document 1] JP 2000-245537 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a table, it is desirable to make the support pillars thin from the viewpoints of improving the design and ensuring space for the lower legs (space below the tabletop). On the other hand, in a table, when a load acts on the legs along the circumferential direction of the support pillars, it is necessary to ensure the connection strength between the support pillars and the legs in order to suppress the displacement of the legs in the direction in which adjacent legs move toward or away from each other in the circumferential direction starting from the connection point between the leg and the support pillar. However, in the conventional configuration, there is still room for improvement in terms of ensuring the connection strength between the support pillars and the legs while making the support pillars thin.

[0005] The present invention aims to provide an item support fixture that can improve design while ensuring the connection strength between the support posts and legs. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. An item support fixture according to one embodiment of the present invention comprises a support pillar extending in the vertical direction, a support member located at the upper end of the support pillar, an item support section supported from below by the support member and supporting an item, and legs extending from the support pillar in a direction intersecting the vertical direction and contacting a floor surface, the support member and the item support section being fixed so that the orientation of the item support section relative to the support member can be adjusted in a circumferential direction around the axis of the support pillar along the vertical direction.

[0007] In the above aspect, it is preferable that a slit extending in the circumferential direction is formed in the receiving member on a virtual circle centered on the axis, the item support portion has a fixing portion exposed through the slit on the circumference, the exposed position of the fixing portion within the slit can be changed in the circumferential direction depending on the circumferential orientation of the item support portion relative to the receiving member, and a connecting member is fixed to the fixing portion through the slit from below the receiving member. Effect of the Invention

[0008] According to each of the above aspects, it is possible to ensure the connection strength between the support and the leg while improving the design. [Brief description of the drawings]

[0010] Next, an embodiment of the present invention will be described based on the drawings. In the embodiments and modified examples described below, the same reference numerals may be used to designate corresponding configurations, and the description may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," not only strictly indicate such arrangements, but also indicate a state in which the two surfaces are relatively displaced with an angle or distance to the extent that a tolerance or the same function is obtained. In this embodiment, "facing" does not only mean a case in which the orthogonal directions (normal directions) of the two surfaces are aligned with each other, but also includes a case in which the orthogonal directions intersect with each other. In the following description, the direction perpendicular to the floor surface F on which the article support fixture 1 is installed is the up-down direction (arrow UP is upward), and the directions perpendicular to the up-down direction are the front-rear direction (arrow FR is forward) and the left-right direction (arrow LH is left), respectively.

[0011] (First embodiment) [Item support fixture 1] FIG. 1 is a perspective view of an article support fixture 1. FIG. The article support fixture 1 shown in Fig. 1 is a table. The article support fixture 1 is installed in various facilities (for example, offices, public facilities, stores, etc.). The article support fixture 1 includes a support structure 11 and a top plate 12.

[0012] <Support structure 11> The support structure 11 is placed on the floor surface F and supports the top plate 12 from below. The support structure 11 includes a support column 20, a support leg 21, and a mounting bracket 22.

[0013] Fig. 2 is an exploded perspective view of the support structure 11. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. 2 and 3, the support pillar 20 extends in the up-down direction. The support pillar 20 includes a leg attachment member 31 and an extension member 32. In the following description, a direction intersecting the axis O1 of the support pillar 20 in a plan view may be referred to as a radial direction, and a direction going around the axis O1 may be referred to as a circumferential direction.

[0014] The leg mounting member 31 is formed in a cylindrical shape extending in the vertical direction. That is, the leg mounting member 31 is formed with a through hole (hollow portion) 31a that passes through the leg mounting member 31 in the vertical direction. The leg mounting member 31 is open in the vertical direction through the upper and lower openings of the through hole 31a.

[0015] The leg mounting member 31 has an external thread 35 formed on its upper outer circumferential surface. An insertion portion 36 that penetrates the leg mounting member 31 in the radial direction is formed at the lower part of the leg mounting member 31. The insertion portion 36 communicates the inside and outside of the leg mounting member 31. The insertion portion 36 is opened at the lower end edge of the leg mounting member 31 and is formed in a groove shape extending in the vertical direction. Note that the insertion portion 36 does not have to be opened at the lower end edge of the leg mounting member 31 as long as it is configured to communicate the inside and outside of the leg mounting member 31. Also, the leg mounting member 31 does not have to be configured to have a through hole 31a that penetrates in the vertical direction as long as it has at least a hollow portion that communicates with the insertion portion 36.

[0016] A plurality of the insertion portions 36 are formed at intervals in the circumferential direction in the leg mounting member 31. Specifically, a total of four insertion portions 36 are formed at 90° intervals in the leg mounting member 31. In the following description, of the four insertion portions 36, the insertion portions 36 facing each other in the X direction (first direction) intersecting the front-rear direction and the left-right direction may be referred to as the first insertion portion 36a and the second insertion portion 36b, and the insertion portions 36 facing each other in the Y direction (second direction) perpendicular to the X direction may be referred to as the third insertion portion 36c and the fourth insertion portion 36d.

[0017] The extension member 32 is formed in a cylindrical shape arranged coaxially with the axis O1. In this embodiment, the outer diameter of the extension member 32 is formed to be the same as that of the leg attachment member 31. In the extension member 32, a male thread portion 37 (see FIG. 5) is formed on the outer peripheral surface of the upper end portion. In the extension member 32, a female thread portion 38 is formed on the inner peripheral surface of the lower end portion. The male thread portion 35 of the leg attachment member 31 is screwed into the female thread portion 38. As a result, the extension member 32 extends upward from the upper end portion of the leg attachment member 31. The outer diameter of the leg attachment member 31 and the outer diameter of the extension member 32 may be different from each other. Also, the leg attachment member 31 may be formed with a female thread portion, and the extension member 32 may be formed with a male thread portion. The attachment method of the leg attachment member 31 and the extension member 32 is not limited to screwing, but may be appropriately selected such as press-fitting or welding. Also, the leg attachment member 31 and the extension member 32 may be formed integrally. The extension member 32 may be divided into a plurality of parts in the vertical direction.

[0018] The support leg 21 is in contact with a floor surface F. The support leg 21 is formed in an X shape in which a first grounding member 41 and a second grounding member 42 intersect on an axis O1. The first grounding member 41 is formed in a plate shape extending in the X direction with the Y direction as its thickness direction. A first engagement groove 45 that opens downward is formed in the center of the first grounding member 41 in the X direction. The upper end of the first engagement groove 45 is located in the middle of the first grounding member 41 in the up-down direction.

[0019] The first grounding member 41 is attached to the leg mounting member 31 from below. Specifically, the first grounding member 41 is inserted into the leg mounting member 31 from below through the lower end openings of the first insertion portion 36a and the second insertion portion 36b so as to traverse the leg mounting member 31 in the X direction. At this time, the first engagement groove 45 is located on the axis O1.

[0020] The second grounding member 42 is formed in a plate shape extending in the Y direction with the thickness direction being in the X direction. A second engagement groove 46 that opens upward is formed in the center of the second grounding member 42 in the Y direction. The lower end of the second engagement groove 46 is located in the middle of the second grounding member 42 in the up-down direction.

[0021] The second grounding member 42 is attached to the leg mounting member 31 from below. Specifically, the second grounding member 42 is inserted into the leg mounting member 31 from below through the lower end openings of the third insertion portion 36c and the fourth insertion portion 36d so as to traverse the leg mounting member 31 in the Y direction. At this time, the first grounding member 41 and the second grounding member 42 are combined with each other in a state in which the second grounding member 42 is inserted into the first engagement groove 45 from below and the first grounding member 41 enters the second engagement groove 46 from above.

[0022] The first grounding member 41 and the second grounding member 42 are fixed to each other and to the leg mounting member 31 within the leg mounting member 31 by welding. Specifically, the first grounding member 41 and the second grounding member 42 are welded to the opening edges of the corresponding insertion portions 36 from the inside of the leg mounting member 31. The first grounding member 41 and the second grounding member 42 are welded to each other at their intersections (opening edges of the engagement grooves 45, 46). Therefore, the weld marks between the support leg 21 and the leg mounting member 31 are not exposed to the outside of the support structure 11.

[0023] The support leg 21 of this embodiment is constituted by the above-mentioned first grounding member 41 and second grounding member 42, and includes a plurality of legs 50a to 50d extending radially with respect to the axis O1. Specifically, the portion of the first grounding member 41 located on the +X side with respect to the axis O1 constitutes the first leg 50a extending from the leg mounting member 31 to the +X side through the first insertion portion 36a. The portion of the first grounding member 41 located on the -X side with respect to the axis O1 constitutes the second leg 50b extending from the leg mounting member 31 to the -X side through the second insertion portion 36b. The portion of the second grounding member 42 located on the +Y side with respect to the axis O1 constitutes the third leg 50c extending from the leg mounting member 31 to the +Y side through the third insertion portion 36c. The portion of the second grounding member 42 located on the -Y side with respect to the axis O1 constitutes the fourth leg 50d extending from the leg mounting member 31 to the -Y side through the fourth insertion portion 36d. The distal end (the radially outer end) of each of the legs 50a to 50d is in contact with the floor surface F. The amount of protrusion of each of the legs 50a to 50d from the leg attachment member 31 may differ from one another.

[0024] In this manner, the base ends (diametrically inner ends) of the legs 50a to 50d are fixed to each other within the leg attachment member 31. Specifically, the first leg 50a and the second leg 50b are integrally formed by the first grounding member 41. The third leg 50c and the fourth leg 50d are integrally formed by the second grounding member 42. Moreover, the first leg 50a is integrally connected to the second grounding member 42 (the third leg 50c and the fourth leg 50d) by welding. The second leg 50b is integrally connected to the second grounding member 42 (the third leg 50c and the fourth leg 50d) by welding.

[0025] Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 1. Fig. 5 is a cross-sectional view taken along line VV in Fig. 4. As shown in FIGS. 4 and 5, the mounting bracket 22 is a member that is located at the upper end of the extension member 32 and is connected to the top plate 12. The mounting bracket 22 includes a joint portion 61 and a top board receiving member (receiving member) 62. The joint portion 61 is formed in a cylindrical shape arranged coaxially with the axis O1. The outer diameter of the joint portion 61 is formed to be the same as the outer diameter of the extension member 32. An internal thread portion 65 is formed on the inner peripheral surface of the joint portion 61. The external thread portion 37 is screwed into the internal thread portion 65. The outer diameter of the joint portion 61 and the outer diameter of the extension member 32 may be different from each other. The method of attaching the joint portion 61 and the extension member 32 is not limited to screwing, and may be appropriately selected such as press fitting or welding. The joint portion 61 and the extension member 32 may be formed integrally.

[0026] The table top support member 62 is formed in a disk shape arranged coaxially with the axis O1. The table top support member 62 is fixed to the upper end of the joint portion 61 by welding or the like. The table top support member 62 protrudes from the upper end of the joint portion 61 radially outward.

[0027] A plurality of slits 68 are formed in the outer periphery of the top board receiving member 62. Each slit 68 is formed in an arc shape extending along the circumferential direction. Each slit 68 is formed at intervals in the circumferential direction on an imaginary circle K centered on the axis O1. In the illustrated example, the circumferential length of the slits 68 is equal to the interval between adjacent slits 68 in the circumferential direction (hereinafter referred to as blank areas 69). However, the circumferential length of the slits 68 may be greater or smaller than the blank areas 69.

[0028] <Tabletop 12> The top plate 12 is, for example, square-shaped in plan view. The upper surface of the top plate 12 constitutes an article support surface that supports articles and the like. The top plate 12 is arranged in the front-rear direction with a pair of sides of the four sides constituting the outer periphery facing each other in the left-right direction, and the remaining pair of sides are arranged in the left-right direction facing each other in the front-rear direction. Therefore, each corner (vertex) of the top plate 12 is arranged facing the +X side, the -X side, the +Y side, and the -Y side. The shape of the top plate 12 in plan view can be appropriately changed to a polygonal shape such as a rectangular shape or a triangular shape, a circular shape, a semicircular shape, or the like.

[0029] The top plate 12 is connected to the mounting bracket 22 with the center (intersection of the diagonals) in a plan view positioned on the axis O1. Specifically, a plurality of mounting holes (fixing portions) 71 are formed on the lower surface of the top plate 12. The plurality of mounting holes 71 are arranged at intervals in the circumferential direction in a portion positioned on the imaginary circle K described above. The pitch between adjacent mounting holes 71 in the circumferential direction (the center-to-center distance of the mounting holes 71) is, for example, equal to or less than the circumferential length of the slit 68. Therefore, in a state in which the top plate 12 and the mounting bracket 22 are overlapped in the up-down direction, at least one mounting hole 71 is set to overlap in each slit 68 regardless of the orientation of the top plate 12 around the axis O1 relative to the mounting bracket 22. As such an embodiment, for example, when eight mounting holes 71 are formed at equal intervals, it is preferable that the circumferential length of the slit 68 is formed with four mounting holes 71 formed at equal intervals with a central angle of 45° centered on the axis O1 (360°÷8=45°). Furthermore, when 16 mounting holes 71 are formed at equal intervals, it is preferable that four slits 68 are formed at equal intervals with a circumferential length of 22.5° as the central angle centered on the axis O1 (360°÷16=22.5°). In other words, the top plate 12 is configured so that the orientation about the axis O1 with respect to the mounting bracket 22 can be adjusted by adjusting the mounting holes 71 that overlap with the slits 68 of the top plate receiving member 62, among the respective mounting holes 71.

[0030] Of the mounting holes 71, the mounting holes 71 that overlap the slits 68 have screws (connecting members) 75 fastened through the slits 68. In this embodiment, the orientation of the top plate 12 is set so that the grounding members 41 and 42 are arranged on the diagonal of the top plate 12 in a plan view. In a plan view, each of the legs 50a to 50d extends toward a corresponding corner (vertex) of the top plate 12. That is, the first leg 50a extends toward a corner of the top plate 12 on the +X side. The second leg 50b extends toward a corner of the top plate 12 on the -X side. The third leg 50c extends toward a corner of the top plate 12 on the +Y side. The fourth leg 50d extends toward a corner of the top plate 12 on the -Y side.

[0031] <Assembly method of the article support fixture 1> Next, a method for assembling the above-mentioned article support fixture 1 will be described. First, the extension member 32 is assembled to the leg attachment member 31 to which the support leg 21 is fixed. Specifically, the female thread portion 38 of the extension member 32 is screwed into the male thread portion 35 of the leg attachment member 31. Next, the mounting bracket 22 is assembled to the upper end of the extension member 32. Specifically, the female thread portion 65 of the mounting bracket 22 is screwed into the male thread portion 37 of the extension member 32.

[0032] Next, the table top 12 is attached to the mounting bracket 22 (table top receiving member 62). Specifically, first, the table top 12 is set on the table top receiving member 62 so that the center of the table top 12 is located on the axis O1. Next, the table top 12 is rotated about the axis O1 relative to the table top receiving member 62 so that each vertex of the table top 12 is located on an extension line of the corresponding leg 50a to 50d in a plan view. This changes the circumferential position of each mounting hole 71 relative to the slit 68. Screws 75 are screwed through the slit 68 into the mounting holes 71 that overlap the slits 68. Through the above steps, the above-mentioned article support fixture 1 is assembled.

[0033] In this manner, in this embodiment, the base ends of the multiple legs 50a to 50d are fixed to the leg attachment member 31 in a state where they are integrally connected to each other within the through-hole 31a. According to this configuration, the legs 50a-50d support each other within the leg mounting member 31. This ensures stronger connection strength between the legs 50a-50d and the leg mounting member 31 than when each leg is fixed to the leg mounting member individually. Also, the legs 50a-50d and the support 20 can be made thinner than when the legs or leg mounting member are made thicker to ensure stronger connection strength. As a result, the design can be improved.

[0034] In this embodiment, the insertion portion 36 is formed in a groove shape that opens at the lower end edge of the leg mounting member 31. According to this configuration, each of the legs 50a-50d can be fixed to the leg mounting member 31 with the legs 50a-50d inserted from below the leg mounting member 31 through the lower end opening of the insertion portion 36. This improves the workability of the insertion portion 36 compared to a configuration in which the insertion portion is a hole that opens only to the side (radial direction) of the leg mounting member. Therefore, the cost of the article support fixture 1 can be reduced.

[0035] In this embodiment, the support 20 is configured to include a leg attachment member 31 in which a through hole 31a and an insertion portion 36 are formed, and an extension member 32 attached to the upper end of the leg attachment member 31. With this configuration, when the article support fixture 1 is distributed, the leg attachment member 31 to which the legs 50a to 50d are fixed and the extension member 32 can be transported in a disassembled state. This improves transportability. Also, the leg attachment member 31 and the extension member 32 can be manufactured from materials optimal for their respective applications. This improves design freedom.

[0036] In this embodiment, a male thread portion 35 is formed on the outer peripheral surface of the leg mounting member 31, and a female thread portion 38 is formed on the inner peripheral surface of the extension member 32. This configuration simplifies the assembly work of the leg mounting member 31 and the extension member 32. Since no separate member is required to assemble the leg mounting member 31 and the extension member 32, the number of parts can be reduced.

[0037] In this embodiment, the first grounding portion 41 and the second grounding member 42 intersect with each other within the through hole 31a and are fixed to each other at the intersection. According to this configuration, among the multiple legs 50a to 50d, the legs 50a, 50b extending in the X direction and the legs 50c, 50d extending in the Y direction can be integrally formed. This ensures the strength of the legs 50a to 50d and reduces the number of parts.

[0038] In this embodiment, the intersecting portion of the first grounding member 41 and the second grounding member 42 is formed with engagement grooves 45, 46 into which one grounding member is inserted into the other grounding member. This configuration improves the positioning accuracy of the grounding members 41, 42 and ensures the connection strength between the grounding members 41, 42.

[0039] In this embodiment, the article support fixture 1 is configured as a table having a top plate 12. With this configuration, as described above, the article support fixture 1 of this embodiment can have thin legs 50a to 50d and pillars 20, improving the design and ensuring space for the lower legs.

[0040] The top plate 12 of the present embodiment is configured so that the position of the top plate 12 relative to the mounting bracket 22 can be adjusted around the axis O1. According to this configuration, the top plate 12 can be attached to the attachment bracket 22 in a desired direction regardless of dimensional errors of the top plate 12, the attachment bracket 22, etc. In this case, by aligning the legs 50a to 50d with the apex of the top plate 12 and fixing the top plate 12 to the attachment bracket 22, the legs 50a to 50d are not arranged below the side portion of the top plate 12 that the user can easily face. This suppresses interference between the user and the legs 50a to 50d, and allows for effective use of the lower leg space. On the other hand, by aligning the legs 50a to 50d with the apex of the top plate 12 that is farthest from the center of the top plate 12, it is possible to suppress the article support fixture 1 from tipping over when a downward load is applied to the top plate 12. In addition, even when the same support structure 11 is attached to top plates of different planar shapes, the legs can be oriented in the optimal direction for various top plates.

[0041] In this embodiment, the mounting bracket 22 is formed with a circumferentially extending slit 68, and the top plate 12 is formed with a mounting hole 71a exposed through the slit 68. With this configuration, the exposed position of the mounting hole 71a within the slit 68 is changed in the circumferential direction according to the circumferential orientation of the top plate 12 relative to the mounting bracket 22. As a result, with the top plate 12 aligned in a desired orientation relative to the mounting bracket 22, a screw 75 is fastened into the mounting hole 71a through the slit 68. As a result, the top plate 12 can be attached to the mounting bracket 22 in a desired orientation.

[0042] (Modification) In the above embodiment, the axis O1 is located at the center of the square tabletop 12, and the four legs 50a to 50d are directed toward each vertex of the tabletop 12. However, the present invention is not limited to this configuration. For example, as shown in Fig. 6, the axis O1 may be located on the center of gravity O2 of a triangular tabletop 150. In this case, the orientation of the tabletop 150 relative to the support column 20 may be adjusted so that, for example, the three legs 151a to 151c extend toward each vertex of the tabletop 150. 7, the axis O1 may be located at a position eccentric to the center O3 of the disk-shaped top plate 155. In this case, for example, the orientation of the top plate 155 with respect to the support column 20 may be adjusted so that the two legs 156a and 156b extend in the direction opposite to the eccentric direction of the axis O1. 8, support structures 11 may be provided at both left and right ends of a rectangular tabletop 160. In this case, the orientation of the tabletop 160 with respect to the support columns 20 may be adjusted for each support structure 11. In the illustrated example, two legs 161a, 161b of each support structure 11 extend in directions separating them in the front-rear direction as they move outward in the left-right direction, and point to each vertex of the tabletop 160.

[0043] Second embodiment 9 is a cross-sectional perspective view of a support structure 11 according to a second embodiment. This embodiment differs from the first embodiment in that a leg mounting member 31 and an extension member 32 are connected via connecting plates (a first plate 100 and a second plate 101). In the support structure 11 shown in FIG. 9, the first plate 100 closes the upper end opening of the leg mounting member 31. The first plate 100 is formed in a disk shape that is smaller than the outer diameter of the leg mounting member 31 and larger than the inner diameter of the leg mounting member 31. The first plate 100 is disposed on the upper end edge of the leg mounting member 31, protruding upward from the leg mounting member 31 and receding radially inward from the outer circumferential surface of the leg mounting member 31. The first plate 100 is integrally formed with the leg mounting member 31 by casting or the like. However, the first plate 100 may be fixed to the leg mounting member 31 by welding or the like.

[0044] In the first plate 100, in portions that do not overlap with the support legs 21 in a plan view (positions shifted in the circumferential direction), insertion holes 100a are formed that penetrate the first plate 100 in the up-down direction. In this embodiment, the insertion holes 100a are formed in the first plate 100 in portions that are located between the adjacent legs 50a to 50d, respectively.

[0045] The second plate 101 closes the lower end opening of the extension member 32. The second plate 101 is fixed by welding or the like to a portion of the extension member 32 that is located above the lower end edge by the thickness of the first plate 100. A fastening hole 101a is formed in the second plate 101 at a portion that overlaps with the above-mentioned insertion hole 100a in a plan view.

[0046] In this embodiment, to assemble the leg mounting member 31 and the extension member 32, the first plate 100 is inserted into the extension member 32 from below. This causes the first plate 100 and the second plate 101 to abut against each other in the vertical direction.

[0047] Next, the leg mounting member 31 and the extension member 32 are rotated relative to each other around the axis O1, and the insertion hole 100a of the first plate 100 and the fastening hole 101a of the second plate 101 are aligned in a plan view. Next, the screw 110 is inserted from below the leg mounting member 31 through the gap between the adjacent legs 50a to 50d. Then, after inserting the screw 110 into the insertion hole 100a, the screw 110 is fastened into the fastening hole 101a. This completes the assembly of the leg mounting member 31 and the extension member 32.

[0048] In this embodiment as well, the first plate 100 and the second plate 101 are fastened together by screws 110 passing between the legs 50a to 50d. This makes it possible to connect the leg mounting member 31 and the extension member 32 without making them thicker. This makes it possible to achieve the same effects as the first embodiment described above.

[0049] Third embodiment This embodiment differs from the above-described embodiments in that it does not include a mounting bracket 22. Fig. 10 is an exploded perspective view of an article support fixture 1 according to the third embodiment, as viewed from below. In the article support fixture 1 shown in Fig. 10, a male thread portion (top board receiving member) 37 is formed on the outer circumferential surface of the upper end portion of an extension member 32.

[0050] The top plate 200 includes a top plate main body 201 and an attachment tube 202 . The tabletop body 201 is formed in a disk shape that is arranged coaxially with the axis O1. The mounting tube 202 is formed in a cylindrical shape arranged coaxially with the axis O1. The mounting tube 202 is fixed to the underside of the tabletop main body 201 by welding or the like. An internal thread portion 203 is formed on the inner peripheral surface of the mounting tube 202. The internal thread portion 203 is screwed into the external thread portion 37 of the extension member 32. In this way, the tabletop 200 is attached to the upper end portion of the support 20.

[0051] As in this embodiment, by connecting the extension member 32 and the top plate 200 themselves by screwing, it is possible to improve the ease of assembly.

[0052] A spacer such as a washer may be interposed in the male thread portion 37. In this case, the orientation of the tabletop body 201 about the axis O1 relative to the support column 20 can be adjusted depending on the presence or absence of the spacer and its thickness.

[0053] 11, the extension member 32 may be attached to the tabletop 200 by inserting the upper end into the mounting tube 202. In this case, the position of the tabletop 200 around the axis O1 with respect to the extension member 32 may be fixed by abutting a set screw 210 that penetrates the mounting tube 202 in the radial direction against the extension member 32. In this modification, the orientation of the tabletop 200 around the axis O1 with respect to the extension member 32 can be adjusted by adjusting the abutting position of the set screw 210 with respect to the extension member 32. That is, the upper end of the extension member 32 functions as a tabletop receiving member. Note that the orientation of the tabletop 200 around the axis O1 with respect to the extension member 32 may be adjusted using a pin or the like that penetrates the upper end of the mounting tube 202 and the extension member 32 in the radial direction instead of the set screw 210.

[0054] (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 scope of the attached claims. In the above-described embodiment, a table has been described as an example of the item support fixture, but the present invention is not limited to this configuration. The item support fixture may be a cart device, an IV stand, a monitor stand, or the like. When the item support fixture is used in a cart device, the shelf board or top board becomes the item support part. When the item support fixture is used in an IV stand, the hook for hanging an infusion pack becomes the item support part. When the item support fixture is used in a monitor stand, the bracket for supporting the monitor becomes the item support part.

[0055] In the above embodiment, a configuration has been described in which the orientation of the tabletop relative to the support column 20 is adjustable, but the present invention is not limited to this configuration. The tabletop may be configured such that the orientation of the tabletop relative to the support column 20 cannot be adjusted. In the above-described embodiment, the first grounding member 41 and the second grounding member 42 are inserted into each other's engagement grooves 45, 46, but the present invention is not limited to this configuration. The first grounding member 41 and the second grounding member 42 may simply be fixed in a superimposed state. Moreover, the ground members 41 and 42 may be independent of each other.

[0056] In each of the above-mentioned embodiments, the first leg 50a and the second leg 50b are integrally formed as the first grounding member 41, and the third leg 50c and the fourth leg 50d are integrally formed as the second grounding member 42. However, the present invention is not limited to this configuration. For example, at least two of the legs 50a to 50d may be integrally connected to each other by welding or the like in the leg mounting member 31. The number of legs is not limited to four, and may be two, three, five or more. In this case, it is sufficient that at least two of the legs are integrally connected to each other in the leg mounting member 31.

[0057] In the above embodiment, the leg mounting member 31 and the first and second grounding members 41 and 42 are fixed to each other by welding, but the present invention is not limited to this configuration. The leg mounting member 31 and the first and second grounding members 41 and 42 may be fixed to each other by an adhesive filled in the leg mounting member 31 or by a mounting bracket disposed in the leg mounting member 31. In the above-described embodiment, the legs extend radially from the lower end of the support pole, but the present invention is not limited to this configuration. The legs may extend radially from the middle of the support pole in the up-down direction.

[0058] A part or all of the item support fixture according to the above-described embodiment may be supplemented as follows. [Appendix 1] A support pillar extending in the vertical direction; A receiving member located at an upper end of the support pillar; an article support portion supported from below by the receiving member and supporting an article; legs extending from the support in a direction intersecting the vertical direction and in contact with a floor surface; The item support fixture has a receiving member and an item support part fixed so that the orientation of the item support part relative to the receiving member can be adjusted in a circumferential direction around the axis of the support column along the vertical direction.

[0059] According to the configuration of [Appendix 1], the article support part can be attached to the receiving member in a desired direction regardless of dimensional errors of the receiving member, the article support part, etc. In this case, for example, for a top plate (article support part) that is rectangular in plan view, the legs can be aligned with the apex of the top plate and the top plate and the receiving member can be fixed, so that the legs are not positioned below the edge part of the top plate that the user can easily face. This reduces interference between the user and the legs, and allows the lower leg space to be used effectively. In addition, by aligning the legs with the apex of the top plate that is farthest from the center of the top plate, it is possible to prevent the furniture from falling over when a downward load is applied to the top plate.

[0060] [Appendix 2] In the article support fixture described in [Appendix 1] above, The receiving member is formed with a slit extending in the circumferential direction on a virtual circle centered on the axis line, the article support portion includes a fixing portion that is exposed through the slit on the circumference, and the fixing portion is capable of changing an exposed position within the slit in the circumferential direction according to an orientation of the article support portion relative to the receiving member in the circumferential direction, An item support fixture in which a connecting member is fixed to the fixed portion from below the receiving member through the slit.

[0061] According to the configuration of [Appendix 2], the exposed position of the fixing part in the slit is changed in the circumferential direction according to the circumferential orientation of the article support part relative to the receiving member. With the article support part aligned in the desired direction relative to the receiving member, the connecting member is fastened to the fixing part through the slit. As a result, the article support part can be attached to the receiving member in the desired direction.

[0062] In the above-mentioned configuration, the legs do not need to extend radially, and may be, for example, disk legs or the like. Furthermore, the combination of the connecting member and the fixing portion is not limited to the screw 75 and the mounting hole 71. For example, a pin may be used as the connecting member and a press-fit hole may be used as the fixing portion. Also, a nut may be used as the connecting member and a threaded portion may be used as the fixing portion. The combination is not limited to the screw 75, and may be a pin, nut, etc.

[0063] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
