Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in an article support fixture, when a relatively large article such as a monitor is attached in front of the stand, for example, the horizontal bar may be covered from the front by the article. In this case, in a configuration like the bracket of the above - mentioned conventional technology that clamps the horizontal bar in the front - rear direction, there is a problem that the attachment workability of the bracket is poor.

[0005] An object of the present invention is to provide an article support fixture capable of improving the attachment workability when supporting a plurality of articles.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention adopts the following aspects. An article support fixture according to one aspect of the present invention comprises: a first article support section that supports a first article on one side in the front-rear direction; a horizontal rod member that extends in the left-right direction on one side in the up-down direction relative to the first article support section; and a second article support section that sandwiches the horizontal rod member in the up-down direction and supports a second article.

[0007] According to this embodiment, since the second article support portion is configured to sandwich the horizontal rod member in the vertical direction, even when the first article is supported on one side of the first article support portion in the front-rear direction, interference between the second article support portion and the first article can be suppressed when the second article support portion is installed. Therefore, when supporting multiple articles, the ease of installation can be improved.

[0008] In the article support fixture according to the above embodiment, it is preferable that the second article support portion comprises a first clamp portion having a first contact portion that abuts the horizontal rod member from one side in the vertical direction, a second clamp portion having a second contact portion that abuts the horizontal rod member from the other side in the vertical direction, and an adjustment mechanism that connects the first clamp portion and the second clamp portion and moves the first contact portion and the second contact portion closer together or further apart in the vertical direction by rotational operation around an axis. According to this embodiment, the holding force of the second article support on the horizontal rod member can be adjusted by adjusting the amount of rotation of the adjustment mechanism. This makes it possible to further improve the ease of installation.

[0009] In the article support fixture according to the above embodiment, the first clamp portion comprises an extended portion that extends to the other side in the vertical direction from the first contact portion on the other side in the front-rear direction relative to the horizontal rod member, and a first opposing portion that extends from the extended portion to one side in the front-rear direction and faces the horizontal rod member on the other side in the vertical direction relative to the horizontal rod member, the second clamp portion comprises a second opposing portion that faces the first opposing portion on the other side in the vertical direction relative to the first opposing portion, and the adjustment mechanism preferably includes an adjustment bolt that is tightened through a through hole formed in the second opposing portion into a female screw hole formed in the first opposing portion. According to this embodiment, since the adjustment bolt is positioned facing the horizontal rod member in the vertical direction, the tightening force of the adjustment bolt can be effectively applied to the first clamp portion and the second clamp portion. Furthermore, compared to a configuration in which, for example, an adjustment bolt is placed on the other side in the front-rear direction relative to the horizontal rod member, the amount of protrusion of the second article support part on the other side in the front-rear direction relative to the horizontal rod member can be reduced. This makes it possible to suppress the increase in the size of the article support fixture in the front-rear direction that occurs when the second article support part is added.

[0010] In the article support fixture according to the above embodiment, the second clamp portion has a lower end portion that constitutes the second contact portion, and is provided with side wall portions that extend from both ends in the left-right direction of the second opposing portion to one side in the up-down direction, and it is preferable that the side wall portions are arranged on both sides in the left-right direction with respect to the first opposing portion. According to this embodiment, the contact between the first opposing portion and the side wall portion restricts the relative movement of the first clamp portion and the second clamp portion in the left-right direction. This makes it easier to align the through hole and the female screw hole when assembling the first clamp portion and the second clamp portion. As a result, the ease of installation can be further improved.

[0011] In the article support fixture according to the above embodiment, it is preferable that at least one of the first clamp portion and the second clamp portion is provided with a guide portion that extends vertically on one side in the front-rear direction relative to the horizontal rod member. According to this embodiment, by providing a guide portion on one side in the front-rear direction relative to the horizontal rod member, the movement of the second article support portion to the other side in the front-rear direction relative to the horizontal rod member can be restricted. As a result, the second article support portion can be stably attached to the horizontal rod member.

[0012] In the article support fixture according to the above embodiment, it is preferable that the first article support portion is connected to the horizontal rod member. According to this embodiment, when the first article support is connected to the horizontal rod member, the first article will be positioned close to the horizontal rod member. Even in such a case, this embodiment makes it possible to suppress interference between the second article support and the first article when the second article support is attached.

[0013] In the article support fixture according to the above embodiment, it is preferable that the second article support portion comprises a bracket extending from the horizontal rod member to one side in the vertical direction, and a tray extending from one end of the bracket in the vertical direction to one side in the front-rear direction, on which the second article is supported. According to this embodiment, since the bracket extends from the horizontal rod member to one side in the vertical direction, even when the horizontal rod member is positioned behind the first article, the tray can be wrapped around to one side in the front-to-back direction relative to the first article. This improves the usability of the second article support. [Effects of the Invention]

[0014] According to each of the above embodiments, the ease of installation can be improved when supporting multiple articles. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Next, embodiments of the present invention will be described based on the drawings. In the embodiments and modifications described below, corresponding configurations may be denoted by the same reference numerals and the description thereof may be omitted. In the following description, expressions indicating relative or absolute arrangements such as "parallel", "orthogonal", "center", "coaxial", etc. not only strictly represent such arrangements, but also represent states in which they are relatively displaced with tolerances and angles or distances that can obtain the same function. Further, in the present embodiment, "opposite" includes not only the case where the orthogonal directions (normal directions) of two surfaces coincide with each other, but also the case where the orthogonal directions intersect each other.

[0017] [Article Support Fixture 1] FIG. 1 is a perspective view of the article support fixture 1 seen from the front. The article support fixture 1 shown in FIG. 1 is, for example, a monitor stand capable of supporting a monitor (first article) M. The article support fixture 1 is installed in an indoor space such as an office or a public facility, and is used for a plurality of users to share information on a large screen in a video conference or a web conference. In the following description, the direction orthogonal to the floor surface F is defined as the vertical direction (arrow UP is the upper side), and the two directions orthogonal to the vertical direction are defined as the front-rear direction (arrow FR is the front side) and the left-right direction (arrow LH is the left side), respectively.

[0018] The article support fixture 1 includes a stand main body 2 and an option member 3 detachably attached to the stand main body 2.

[0019] <Stand Main Body 2> The stand body 2 comprises a base 11, a support frame 12, a cross beam member 13, and a monitor support 14. The base portion 11 is formed in a plate shape with the vertical direction being the thickness direction. The base portion 11 is configured to be able to move on the floor surface F via casters 15. The stand body 2 may be configured without casters 15.

[0020] The support frame 12 is formed in a rectangular frame shape when viewed from the front or back. The support frame 12 comprises a lower frame portion 21, a pair of vertical frame portions 22, and an upper frame portion 23. The lower frame portion 21 extends in the left-right direction. The lower frame portion 21 is connected to the base portion 11 at the center of the base portion 11 in the front-rear direction, traversing the base portion 11 in the left-right direction. The vertical frame portion 22 extends upward from both the left and right ends of the lower frame portion 21. A handle 27 is provided on the outer surface (the surface facing outward in the left and right directions) of the vertical frame portion 22. The handle 27 is formed in an annular shape from a flexible strip-shaped member. The upper frame section 23 spans the space between the upper ends of the pair of vertical frame sections 22. The upper frame section 23 faces the lower frame section 21 in the vertical direction and extends parallel to the lower frame section 21.

[0021] The horizontal beam member 13 spans the lower parts of a pair of vertical frame sections 22 between the lower frame section 21 and the upper frame section 23. The horizontal beam member 13 faces the lower frame section 21 in the vertical direction and extends parallel to the lower frame section 21. The horizontal beam member 13 and each of the frame sections 21-23 are formed in a rectangular tubular shape. Wiring and the like can be housed inside the horizontal beam member 13 and each of the frame sections 21-23. However, the horizontal beam member 13 and each of the frame sections 21-23 may be formed in a cylindrical shape or the like, or they may be formed solid.

[0022] The monitor support 14 is the portion enclosed by the support frame 12 and is positioned above the crossbeam member 13. The monitor support 14 comprises a pair of horizontal rod members (lower horizontal rod member 31 and upper horizontal rod member 32) and a pair of vertical rod members 33. Each horizontal rod member (rod member) 31, 32 faces each other in the vertical direction and extends parallel to the left-right direction (first direction). Each horizontal rod member 31, 32 spans between the vertical frame sections 22. In the illustrated example, each horizontal rod member 31, 32 is connected to the vertical frame section 22 at its rear. The cross-sectional view of each horizontal rod member 31, 32, as seen from the left-right direction, is formed in a rectangular shape with the vertical direction as the longitudinal direction and the front-back direction as the short direction. However, the cross-sectional shape of each horizontal rod member 31, 32 can be changed as appropriate, such as to a circular shape.

[0023] The vertical rod members 33 are positioned facing each other in the left-right direction and extend parallel to each other in the up-down direction (second direction). Each vertical rod member 33 spans the space between each horizontal rod member 31, 32 at the center of the horizontal direction of each horizontal rod member 31, 32. The cross-sectional view of each vertical rod member 33, as seen from above, is formed in a U-shape that opens to the rear. Monitor mounting holes 33b are formed in the front wall portion 33a of each vertical rod member 33. The monitor mounting holes 33b penetrate the front wall portion 33a in the front-rear direction. Multiple monitor mounting holes 33b are formed in the front wall portion 33a of each vertical rod member 33, spaced apart in the vertical direction.

[0024] The vertical rod members 33 support the monitor M from the rear (the other side in the front-to-back direction, and one side in the first direction). The monitor M is, for example, a liquid crystal monitor or an organic EL (electro-luminescence) monitor. Various information is displayed on the display surface of the monitor M, which faces forward. In a plan view from the front-to-back direction, the monitor M is formed in a rectangular shape in which the vertical dimension is larger than the dimension between the horizontal rod members 31 and 32, and the horizontal dimension is larger than the dimension between the vertical rod members 33.

[0025] The rear surface of the monitor M has screw holes formed in a position and size that conforms to the VESA FPMPMI Standard established by VESA (Video Electronics Standards Association). The monitor M is fixed to the vertical rod member 33 by screwing screws into the screw holes through the appropriate monitor mounting holes 33 described above. In this way, the monitor M is supported by the stand body 2 in the portion enclosed by the support frame 12, at the front (one side in the front-to-back direction) of the monitor support 14. When the monitor M is connected to the monitor support 14, the portion of the monitor support 14 excluding the left and right ends of the horizontal rod members 31 and 32 is covered by the monitor M from the front. In addition, there is a gap S in the front-to-back direction (see Figure 3) between the monitor M and the horizontal rod members 31 and 32. The gap S only needs to be provided in at least a portion in the left-to-right direction between the monitor M and the horizontal rod members 31 and 32.

[0026] <Optional component 3> Figure 2 is an exploded perspective view of the optional component 3. As shown in Figures 1 and 2, the optional member 3 can support, for example, a camera (second item) C. The optional member 3 comprises a bracket 41 and a tray (support part) 42. In addition to the camera C, various other items can be used as the items supported by the optional member 3.

[0027] <Bracket 41> Figure 3 is a cross-sectional view corresponding to line III-III in Figure 5. Figure 4 is a cross-sectional view corresponding to line IV-IV in Figure 5. As shown in Figures 3 and 4, the bracket 41 is connected to the lower horizontal rod member 31 by clamping it from above and below. The bracket 41 extends downward from the lower horizontal rod member 31. The bracket 41 comprises a first clamp portion 44, a second clamp portion 45, and an adjustment bolt 46 (see Figure 3).

[0028] The first clamp portion 44 is formed in a rectangular tube shape with its longitudinal direction in the left-right direction and extending in the up-down direction. The first clamp portion 44 is assembled to the lower horizontal rod member 31 from below (one side in the up-down direction and one side in the second direction). The first clamp portion 44 comprises a clamp body 51 and divided pieces 52. The clamp body 51 is formed in a C-shape when viewed in cross-section from above. Specifically, the clamp body 51 comprises a pair of side pieces 51a, a front piece 51b, a flange piece 51c, and a lower piece 51d (see Figure 3).

[0029] Figure 5 is a cross-sectional view corresponding to the VV line in Figure 3. As shown in Figures 3 to 5, the pair of side pieces 51a are arranged below the lower horizontal rod member 31, spaced apart in the left-right direction. The side pieces 51a extend vertically, with the left-right direction being the thickness direction. A pad 55 is attached to the upper end of the side piece 51a. The pad 55 is made of a material with a lower modulus of elasticity than the side piece 51a, such as rubber, and is configured to be elastically deformable. When the bracket 41 is attached to the lower horizontal rod member 31 (hereinafter referred to as the attached state), the upper end of the side piece 51a abuts against the lower surface of the lower horizontal rod member 31 via the pad 55. That is, the upper end of the side piece 51a constitutes the first contact portion in this embodiment. The upper end of the side piece 51a may also be in direct contact with the lower surface of the lower horizontal rod member 31.

[0030] As shown in Figures 3 and 4, the front portion 51b spans the entire vertical distance between the front ends of the side portions 51a. The portion of the front portion 51b that protrudes above the side portions 51a constitutes the guide portion 56. In the installed state, the guide portion 56 is positioned to overlap with the lower crossbar member 31 when viewed from the front-rear direction. The guide portion 56 approaches or abuts against the lower crossbar member 31 from the front. By abutting the lower crossbar member 31 from the front, the guide portion 56 restricts the rearward movement of the first clamp portion 44 relative to the lower crossbar member 31.

[0031] The flange portion 51c extends inward in the left-right direction (towards each other) from the rear end of each side piece 51a. Multiple through holes 51f are formed in the flange portion 51c at intervals in the vertical direction. The through holes 51f penetrate the flange portion 51c in the front-rear direction and are open on the left-right inner edge of the flange portion 51c. As shown in Figure 3, the lower piece 51d extends rearward from the lower end of the front piece 51b. The front-to-rear dimension of the lower piece 51d is smaller than that of the side piece 51a. A pad 58 is attached to the rear end of the lower piece 51d. The pad 58 is made of the same material as the pad 55 described above and is elastically deformable.

[0032] As shown in Figures 3 and 4, the divided piece 52 is formed in an L-shape when viewed in cross-section from the left and right directions. The divided piece 52 comprises a backing portion 59 and a first opposing portion 60. The backing portion 59 extends vertically with the front-to-back direction being the thickness direction. The backing portion 59 is connected to each flange portion 51c by welding or the like, facing the front portion 51b in the front-to-back direction. This closes the rear opening of the clamp body 51. Through holes 59a are formed in the portion of the backing portion 59 that overlaps with each through hole 51f when viewed from the front-to-back direction.

[0033] The backing portion 59 protrudes from the front portion 51b on both sides in the vertical direction. The portion of the backing portion 59 that protrudes below the front portion 51b constitutes the downward extension portion 59b. A communication opening 59c is formed between the backing portion 59 and the lower portion 51d (pad 58), connecting the inside and outside of the clamp body 51. The communication opening 59c is open in the vertical direction. Of the backing portion 59, the portion that protrudes above the front piece portion 51b constitutes the upper extension portion (extension portion) 59d. In the installed state, the upper extension portion 59d overlaps with the lower crossbar member 31 when viewed from the front-rear direction and protrudes above the lower crossbar member 31. The upper extension portion 59d approaches or abuts against the lower crossbar member 31 from the rear. In the installed state, the guide portion 56 and the upper extension portion 59d face each other in the front-rear direction with the lower crossbar member 31 in between. By abutting the lower crossbar member 31 from the rear, the upper extension portion 59d restricts the forward movement of the first clamp portion 44 relative to the lower crossbar member 31.

[0034] The first opposing portion 60 extends forward from the upper edge of the backing portion 59 (upward extension portion 59d). The front edge of the first opposing portion 60 is located behind the front piece portion 51b. In the first opposing portion 60, a female screw hole 60a (see Figure 3) is formed in the center in the left-right direction. The female screw hole 60a penetrates the first opposing portion 60 in the vertical direction.

[0035] The space enclosed by the upward extension portion 59d, the first opposing portion 60, the side piece portion 51a, and the guide portion 56 of the first clamp portion 44 forms a housing space 61. The housing space 61 penetrates in the left-right direction and is open to the front through an insertion opening 61a formed between the first opposing portion 60 and the guide portion 56. The lower horizontal rod member 31 is housed in the housing space 61 through the insertion opening 61a. Therefore, the insertion opening 61a is formed to a size that allows the lower horizontal rod member 31 to pass through. In the illustrated example, the vertical dimension of the insertion opening 61a is larger than the vertical dimension of the lower horizontal rod member 31.

[0036] As shown in Figures 3 to 5, the second clamp portion 45 is formed in a box shape that opens downwards. The second clamp portion 45 is placed over the first clamp portion 44 from above (on the other side in the vertical direction and the other side in the second direction) above the lower horizontal rod member 31 so as to cover the first opposing portion 60 and the upward extension portion 59d. The second clamp portion 45 comprises a second opposing portion 45a, a pair of side wall portions 45b, a front wall portion 45c, and a rear wall portion 45d.

[0037] The second opposing portion 45a is positioned above the first opposing portion 60, with a gap between them. The front-to-back dimension of the second opposing portion 45a is larger than that of the lower horizontal rod member 31. A through hole 45g (see Figure 3) is formed in the portion of the second opposing portion 45a that overlaps with the female screw hole 60a when viewed from above. The through hole 45g penetrates the second opposing portion 45a in the vertical direction.

[0038] The side wall portion 45b extends downward from both left and right ends of the second opposing portion 45a. An elastically deformable pad 71 is attached to the lower end of the side wall portion 45b. In the installed state, the side wall portion 45b abuts against the upper surface of the lower transverse rod member 31 via the pad 71. Therefore, in the installed state, the lower transverse rod member 31 is sandwiched vertically between the upper end edge of the side piece portion 51a and the lower end edge of the side wall portion 45b. As shown in Figure 5, the side wall portion 45b is located outward in the left and right direction relative to the corresponding side piece portion 51a. However, the corresponding side wall portion 45b and side piece portions 51a may be arranged facing each other in the vertical direction. The lower end of the side wall portion 45b constitutes the second abutment portion in this embodiment. The lower end of the side wall portion 45b may be in direct contact with the upper surface of the lower transverse rod member 31.

[0039] As shown in Figures 3 and 4, the front wall portion 45c extends downward from the front end edge of the second opposing portion 45a. When installed, the front wall portion 45c closes a portion of the insertion opening 61a when viewed from the front-rear direction. The lower end of the front wall portion 45c (the portion located below the side wall portion 45b) constitutes a guide portion that extends vertically in front of the horizontal rod member 31. When installed, the lower end of the front wall portion 45c is positioned within the gap S between the monitor M and the lower horizontal rod member 31. The front wall portion 45c faces the front piece portion 51b (guide portion 56) with a vertical gap between them. Preferably, the gap between the front wall portion 45c and the front piece portion 51b is narrower than the vertical dimension of the lower horizontal rod member 31.

[0040] The rear wall portion 45d extends downward from the rear end edge of the second opposing portion 45a. The rear wall portion 45d overlaps the upward extension portion 59d from the rear. The lower end edge of the rear wall portion 45d is at the same height as the lower end edge of the front wall portion 45c. Therefore, when viewed from the front-rear direction, the rear wall portion 45d overlaps the lower horizontal rod member 31 with the upward extension portion 59d in between.

[0041] As shown in Figures 3 and 5, the adjustment bolt 46 is screwed into the female threaded hole 60a through the through hole 45g. By rotating the adjustment bolt 46 in the tightening direction around its axis, the first clamp portion 44 is pulled upward via the first opposing portion 60. As a result, the lower horizontal rod member 31 is sandwiched vertically between the side wall portion 45b and the side piece portion 51a. On the other hand, by rotating the adjustment bolt 46 in the loosening direction around its axis, the first clamp portion 44 is pulled downward via the first opposing portion 60. In other words, the adjustment bolt 46 moves the first clamp portion 44 and the second clamp portion 45 closer together or further apart in response to the rotational operation.

[0042] When the second clamp portion 45 is placed over the first clamp portion 44, the front wall portion 45c and the rear wall portion 45d cover the lower horizontal rod member 31 and the upper extension portion 59d together from the outside in the front-rear direction. The front wall portion 45c restricts the rearward movement of the second clamp portion 45 relative to the lower horizontal rod member 31 by contacting the lower horizontal rod member 31 from the rear. The rear wall portion 45d restricts the forward movement of the second clamp portion 45 relative to the first clamp portion 44 by contacting the upper extension portion 59d from the front. On the other hand, when the second clamp portion 45 is placed over the first clamp portion 44, the side wall portion 45b covers the backing portion 59 (upper extension portion 59d and first opposing portion 60) from the outside in the left-right direction. The side wall portion 45b restricts the lateral movement of the first clamp portion 44 relative to the second clamp portion 45 by the division piece 52 abutting against it in the left-right direction. Therefore, the second clamping portion 45 is positioned such that the second clamping portion 45 surrounds the first clamping portion 44, thereby restricting the relative rotation of the adjustment bolt 46 around its axis.

[0043] <Tray 42> As shown in Figures 3 and 4, the tray 42 is suspended from the bracket 41. The tray 42 comprises a stay 81, a restricting portion 82, and a tray body 83. The stay 81 is formed in an L-shape when viewed in cross-section from the left or right direction. The stay 81 comprises an entry piece 81a and a support piece 81b.

[0044] As shown in Figures 4 and 5, the entry piece 81a enters the inside of the first clamp portion 44 from below through the communication opening 59c. The entry piece 81a extends vertically with the front-to-back direction being the thickness direction. A female screw hole 81c is formed at the upper end of the entry piece 81a. The female screw hole 81c penetrates the entry piece 81a in the front-to-back direction. Two female screw holes 81c are formed spaced apart in the left-to-right direction. A connecting bolt 84 is fastened to each female screw hole 81c from the rear of the first clamp portion 44 through the through hole 59a and the through hole 51f. Specifically, the female screw hole 81c is positioned so as to overlap one of the through holes 59a and the through hole 51f which are arranged vertically. The connecting bolt 84 is inserted into one of the through holes 59a and the through hole 51f and then fastened to the female screw hole 81c. In other words, the optional member 3 is configured to allow the vertical position of the tray 42 relative to the bracket 41 to be changed by fastening connecting bolts 84 to the female threaded holes 81c through arbitrary through holes 59a and through holes 51f. The tray 42 may also be configured to be immovable relative to the bracket 41.

[0045] As shown in Figure 3, the support piece 81b extends forward from the portion of the entry piece 81a that is located below the lower piece 51d. The front edge of the support piece 81b may be located in front of the vertical frame 22.

[0046] The restricting portion 82 restricts the tray 42 from falling onto the bracket 41. The restricting portion 82 is fixed to the upper end of the entry piece 81a. The restricting portion 82 is formed in an L-shape when viewed in cross-section from the left and right directions. The restricting portion 82 comprises a fixing piece 82a and a restricting piece 82b. The fixing piece 82a is fixed to the upper end of the entry piece 81a by welding or the like. The upper end of the fixing piece 82a protrudes above the entry piece 81a.

[0047] The restricting piece 82b extends forward from the upper end of the fixing piece 82a. At least a portion of the restricting piece 82b faces the lower piece 51d in the vertical direction. The restricting piece 82b is positioned so as to contact the lower piece 51d from above when the tray 42 moves downward relative to the bracket 41.

[0048] As shown in Figures 2 and 3, the tray body 83 comprises a mounting portion 83a and an edge portion 83b. The mounting portion 83a is formed in a plate shape with the vertical direction as the thickness direction. A support piece 81b is fixed to the lower surface of the mounting portion 83a by welding or the like. Therefore, the tray body 83 is supported by the bracket 41 via the stay 81. Below the bracket 41, the mounting portion 83a extends forward and to both the left and right sides. The front edge of the mounting portion 83a protrudes forward beyond the vertical frame portion 22. A camera C is mounted on the mounting portion 83a.

[0049] The edge portion 83b is connected to the outer periphery of the mounting portion 83a. The edge portion 83b protrudes from the outer periphery of the mounting portion 83a in both the vertical and horizontal directions. The edge portion 83b surrounds the entire circumference of the mounting portion 83a.

[0050] [How to attach and detach optional component 3] Next, we will explain how to attach and detach the optional component 3 to the stand body 2. In the following explanation, we will use the case where the optional component 3 is added after the monitor M is already attached to the stand body 2 as an example. Figures 6 and 7 are explanatory diagrams for illustrating how to attach and detach the optional component 3, and are cross-sectional views corresponding to Figure 3.

[0051] To attach the optional component 3 to the stand body 2, first, with the tray 42 fixed to the first clamp portion 44, the first clamp portion 44 is set on the lower horizontal rod member 31. Specifically, as shown in Figure 6, with the insertion opening 61a facing forward, the first clamp portion 44 is brought close to the lower horizontal rod member 31 from the rear. Then, the lower horizontal rod member 31 is housed in the storage space 61 through the insertion opening 61a. Alternatively, with the first clamp portion 44 set on the lower horizontal rod member 31, the first opposing portion 60 may be hooked onto the lower horizontal rod member 31 from above.

[0052] Next, as shown in Figure 7, the second clamp portion 45 is assembled to the first clamp portion 44. Specifically, the second clamp portion 45 is placed over the first clamp portion 44 from above the lower horizontal rod member 31. As a result, the area around the first opposing portion 60 and the upward extension portion 59d is covered by the second clamp portion 45. When assembling the second clamp portion 45, the front wall portion 45c enters the gap S between the monitor M and the lower horizontal rod member 31 from above.

[0053] Next, the first clamp portion 44 and the second clamp portion 45 are tightened with an adjustment bolt 46. Specifically, the adjustment bolt 46 is screwed into the female threaded hole 60a of the first clamp portion 44 through the through hole 59a of the second clamp portion 45. At this time, by rotating the adjustment bolt 46 in the tightening direction, the first clamp portion 44 and the second clamp portion 45 move closer to the lower horizontal rod member 31. At this time, the lower end of the lower horizontal rod member 31 is guided by the guide portion 56 and the backing portion 59 and approaches the upper end of the side piece portion 51a, and the upper end of the lower horizontal rod member 31 is guided by the lower end of the front wall portion 45c and the backing portion 59 and approaches the lower end of the side wall portion 45b. After that, the upper end of the side piece portion 51a and the lower end of the side wall portion 45b both come into contact with the lower horizontal rod member 31 via the pads 55 and 71, respectively, and the installation of the optional member 3 is completed. In other words, the first clamp portion 44 is assembled to the lower horizontal rod member 31 from below, and the second clamp portion 45 is assembled to the lower horizontal rod member 31 from above.

[0054] To remove the optional component 3, the reverse operation of the installation method described above is performed. That is, the second clamp portion 45 is removed from the first clamp portion 44 by rotating the adjustment bolt 46 in the loosening direction. Then, the lower horizontal rod member 31 is retracted from the housing space 61 through the insertion opening 61a. This removes the optional component 3 from the stand body 2.

[0055] Thus, in this embodiment, the system is configured to include a vertical rod member 33 that supports the monitor M at the front, a lower horizontal rod member 31 that extends horizontally below the vertical rod member 33, and a bracket 41 that sandwiches the lower horizontal rod member 31 vertically and supports the tray 42. With this configuration, since the bracket 41 clamps the lower horizontal rod member 31 in the vertical direction, interference between the bracket 41 and the monitor M can be suppressed when attaching the bracket 41, even when the monitor M is supported in front of the stand body 2. Therefore, when supporting multiple items with the stand body 2, the ease of attachment can be improved.

[0056] In this embodiment, the first clamp portion 44 and the second clamp portion 45 are connected to each other, and an adjustment bolt 46 is provided to move the side piece portion 51a and the side wall portion 45b closer together or further apart in the vertical direction by rotational operation around the axis. With this configuration, the holding force of the bracket 41 on the lower horizontal rod member 31 can be adjusted by adjusting the amount of rotation of the adjustment bolt 46. This further improves the ease of installation.

[0057] In this embodiment, the adjustment bolt 46 is tightened through the through hole 45g formed in the second opposing portion 45a into the female screw hole 60a formed in the first opposing portion 60. With this configuration, the adjustment bolt 46 is positioned directly above the lower horizontal rod member 31, so that the tightening force of the adjustment bolt 46 can be effectively applied to the first clamp portion 44 and the second clamp portion 45. Furthermore, compared to a configuration in which, for example, an adjustment bolt is positioned rearward relative to the lower horizontal rod member 31, the amount of protrusion of the bracket 41 rearward relative to the lower horizontal rod member 31 can be reduced. This makes it possible to suppress the increase in the front-to-back size of the article support fixture 1 that occurs when the optional member 3 is added.

[0058] In this embodiment, the second opposing portion 45a is provided with side wall portions 45b extending downward from both ends in the left-right direction, and the side wall portions 45b are arranged on both sides in the left-right direction relative to the first opposing portion 60. With this configuration, the first opposing portion 60 and the side wall portion 45b come into contact, thereby restricting the relative movement of the first clamp portion 44 and the second clamp portion 45 in the left-right direction. This makes it easier to align the through hole 45g and the female screw hole 60a when assembling the first clamp portion 44 and the second clamp portion 45. As a result, the ease of installation can be further improved.

[0059] In this embodiment, the first clamp portion 44 and the second clamp portion 45 are configured to include guide portions (guide portion 56 and front wall portion 45c) that extend vertically in front of the lower horizontal rod member 31. With this configuration, a guide portion is provided in front of the lower horizontal rod member 31, which restricts the rearward movement of the optional member 3 relative to the lower horizontal rod member 31. This allows the optional member 3 to be stably attached to the lower horizontal rod member 31.

[0060] In this embodiment, the vertical rod member 33 is connected to the lower horizontal rod member 31. In this configuration, when the vertical rod member 33 is connected to the lower horizontal rod member 31, the monitor M will be positioned close to the lower horizontal rod member 31. Even in such a case, in this embodiment, interference between the bracket 41 and the monitor M can be suppressed when the bracket 41 is installed.

[0061] In this embodiment, the optional member 3 is configured to include a bracket 41 extending downward from the lower horizontal rod member 31, and a tray 42 extending forward from the lower end of the bracket 41 and supporting the camera C. With this configuration, since the bracket 41 extends downward from the lower horizontal rod member 31, the tray 42 can be positioned in front of the monitor M even when the lower horizontal rod member 31 is located behind the monitor M. This improves the usability of the optional member 3.

[0062] (Other variations) While preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the appended claims. In the embodiments described above, a monitor stand was used as an example of the article support fixture according to the present invention, but the invention is not limited to this configuration. As long as the article support fixture is configured in which a second article support part is assembled vertically to a horizontal rod member, various fixtures such as desks, carts, and cabinets can be used. In the embodiment described above, a configuration in which the optional member 3 is attached to the lower horizontal member 31 has been described, but the configuration is not limited to this. As shown in Figure 8, the optional member 3 may also be attached to the upper horizontal member 32. In the illustrated example, the optional member 3 is attached to the upper horizontal member 32 in an inverted state compared to when it is attached to the lower horizontal member 31. Furthermore, the optional member 3 may be attached to both the lower horizontal member 31 and the upper horizontal member 32. In the embodiment described above, a configuration was described in which the monitor support 14 is connected to the support frame 12, but the configuration is not limited to this. The monitor support 14 may be connected to a support column or the like, or to a wall or the like.

[0063] In the embodiment described above, the case in which an optional member 3 equipped with a tray 42 is used as the second article support part has been explained, but the configuration is not limited to this. The second article support part may be configured to include, for example, a hook or a basket. In the above-described embodiment, a configuration was explained in which the first clamp portion 44 and the second clamp portion 45 are brought closer together by an adjustment bolt 46 to clamp the lower horizontal rod member 31, but the configuration is not limited to this. The first clamp portion 44 and the second clamp portion 45 may be configured to clamp the lower horizontal rod member 31 by a biasing member such as a spring or a link member. Furthermore, the configuration in which the first clamp portion 44 and the second clamp portion 45 are brought closer together by rotation may be achieved, for example, by operating a cam or gear by rotating the adjustment bolt. In the embodiment described above, the adjustment bolt 46 was positioned above the lower horizontal rod member 31, but the configuration is not limited to this. The adjustment bolt 46 may, for example, be provided on the side opposite to the monitor M relative to the lower horizontal rod member 31.

[0064] In the embodiment described above, a configuration in which the horizontal rod members 31, 32 and the vertical rod member 33 are directly connected was described, but the configuration is not limited to this. The vertical rod member 33 and the horizontal rod members 31, 32 do not need to be connected. In the embodiment described above, a configuration was described in which the horizontal rod members 31 and 32 are covered from the front by the monitor M when the monitor M is attached, but the configuration is not limited to this. The horizontal rod members 31 and 32 may be positioned so as not to overlap with the monitor M when viewed from the front or rear direction. In the embodiments described above, a configuration in which the tray 42 is supported by a single bracket 41 was explained, but the configuration is not limited to this. For example, as shown in Figure 9, the tray 42 may be supported by two brackets 41. This makes it possible to use a larger tray 42 or to increase the maximum load capacity of the tray 42.

[0065] In the embodiments described above, an article support fixture 1 capable of supporting multiple articles (for example, a monitor M and a camera C) was described using an example configuration that includes an optional member 3, but the invention is not limited to this configuration. The article support fixture 100 may be configured to support articles using only the optional member 3. For example, the article support fixture 100 shown in Figure 10 includes a rod member 101 extending in the left-right direction (first direction) and optional members 3 that are assembled to the rod member 101 from both sides in the up-down direction (second direction). Alternatively, the optional member 3 may be configured to be assembled to the rod member extending in the up-down direction (first direction) from both sides in the left-right direction (second direction).

[0066] Some or all of the article support fixtures according to the above embodiment may be described as follows: [Note 1] A bracket having a first clamp portion positioned on one side of a second direction intersecting the first direction with respect to a rod member extending in a first direction, and a second clamp portion positioned on the other side of the second direction with respect to the rod member, wherein the rod member is sandwiched between the first clamp portion and the second clamp portion, An optional member comprising a support portion provided on the bracket for supporting an article, The first clamping portion is, A first contact portion that contacts the rod member from one side in the second direction, With respect to the rod member, an extension portion extends from the first contact portion on one side in the first direction to the other side in the second direction, It comprises a first opposing portion that extends from the extended portion to the other side in the first direction and faces the rod member on the other side in the second direction relative to the rod member, The second clamp portion is formed in a box shape that surrounds the extension portion and the first opposing portion, and is placed over the first clamp portion from the other side in the second direction relative to the rod member. The second clamping portion is, A second contact portion that contacts the rod member from the other side in the second direction, It comprises a second opposing portion that faces the first opposing portion on the other side in the second direction relative to the first opposing portion, The bracket is an optional member that connects the first opposing portion and the second opposing portion and includes an adjustment mechanism that moves the first contact portion and the second contact portion closer together or further apart in the second direction by rotational operation around the axis.

[0067] According to the embodiment described in [Appendix 1] above, when attaching the optional member to the rod member, the second clamp portion is placed over the first clamp portion so as to surround the extension portion and the first opposing portion. Therefore, even if the first clamp portion and the second clamp portion are separated, positioning in the direction intersecting the second direction between the first clamp portion and the second clamp portion becomes easier. This improves the ease of installation.

[0068] Furthermore, without departing from the spirit of the present invention, the components in the embodiments described above can be replaced with well-known components as appropriate, and the modifications described above can be combined as appropriate. [Explanation of Symbols]
