Description

[Technical Field]

[0001] The present invention relates to work fixtures. [Background technology]

[0002] Conventionally, various facilities such as offices, research facilities, hospitals, schools, etc. use a wide variety of experimental equipment and measuring instruments depending on the research and experiment content. Furthermore, such facilities require laboratory tables (hereinafter referred to as tabletops) on which to place research and experiment subjects, perform various tasks associated with research and experiments, and record research and experiment results and input them into personal computers. For example, Patent Document 1 listed below discloses a configuration in which a space is provided between opposing top plates to allow maintenance of wiring, piping, and the like of experimental equipment and measuring equipment. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4239365 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration of Patent Document 1, the wiring and piping (infrastructure lines) of the experimental equipment and measuring equipment protrude into the space between the top plates, making the space between the top plates dead space. Therefore, it is necessary to keep the space between the top plates to a certain extent. This makes it difficult to perform maintenance work from the space between the top plates. In particular, when performing maintenance work in the space below the top plates, it is difficult to crawl under the top plates and perform the work.

[0005] The present invention aims to provide a work fixture that makes it easy to perform maintenance work on wiring and piping stored below the top plate, while preventing wiring and the like from being exposed in the space between fixture units. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention employs the following aspects. One embodiment of the present invention provides a work fixture comprising a first fixture unit having a support portion extending upward from the floor surface, a top plate extending to one side of the support portion in a first direction intersecting the vertical direction, with a first space formed below the top plate for accommodating infrastructure cables, a structure provided with a second space on the other side of the support portion in the first direction, and a connecting member connecting the structure to the support portion, and the first fixture unit having a panel member that switches between communication and blocking between the first space and the second space. According to this aspect, the panel member blocks communication between the first and second spaces, preventing the infrastructure wiring housed in the first space of the top plate from being exposed to the second space, improving the aesthetic appearance of the first fixture unit as seen from the second space, and allowing the space surrounded by the first fixture, structure, and connecting material to be used as a general passageway. Furthermore, by communicating the upper space and the second space through at least a portion of the panel member, the upper space can be opened to the second space, making it possible to access the upper space from the second space and facilitating work such as maintenance of the infrastructure lines housed in the upper space.

[0007] In the work fixture of the above aspect, it is preferable that the support part comprises a plurality of pillars arranged at intervals in a second direction that intersects the vertical direction and that intersects the first direction, and that guide the infrastructure wire along the vertical direction, and a cross member that is erected between the plurality of pillars and that guides the infrastructure wire along the second direction. According to this aspect, multiple support columns and cross members can be used as a route for infrastructure cables, making it easier to lay infrastructure cables. Also, the strength of the first furniture unit can be ensured.

[0008] In the work fixture of the above aspect, it is preferable that the panel member is detachably attached to the support portion. According to this aspect, when performing work such as infrastructure line maintenance, the panel member can be removed from the support portion so that the panel member does not get in the way when accessing the first space.

[0009] In the work fixture of the above aspect, it is preferable that the connecting material has a receiving portion that opens upward and can accommodate an infrastructure wire, and a cover member that covers the opening of the receiving portion from above. According to this aspect, by covering the receiving portion with the cover member, the infrastructure wire can be reliably held within the connecting material.

[0010] In the work fixture of the above embodiment, it is preferable that the first fixture unit is removably attached to a portion of the support part located above the top plate and has an upper panel member that blocks communication between the space above the top plate and the second space. According to this aspect, the upper panel member blocks communication between the upper space and the second space, preventing the infrastructure wiring housed in the space above the top plate from being exposed to the second space, thereby improving the aesthetic appearance of the first fixture unit as seen from the second space and allowing the space surrounded by the first fixture, structure, and connecting material to be used as a general passageway. Furthermore, by opening a portion of the upper panel member or removing the upper panel member itself to connect the first space to the second space, the first space can be opened to the second space, making it possible to access the first space from the second space and facilitating work such as maintenance of the infrastructure cables housed in the first space.

[0011] In the work fixture of the above aspect, it is preferable that the structure is a second fixture unit having a top plate that extends to the other side of the first direction relative to the second space. According to this aspect, the first fixture unit and the second fixture unit each have a top plate that protrudes toward the side away from the second space, making it possible to provide work fixtures that are easy to use.

[0012] In the work fixture of the above aspect, it is preferable that the connecting material is installed between the support part and the upper end part of the structure. According to this aspect, by connecting the support part and the upper end of the structure with the connecting material, the connecting material can be provided above the second space, which prevents the connecting material from getting in the way when the second space is used as a general passageway.

[0013] In the work fixture of the above aspect, it is preferable that the connecting members are provided in pairs spaced apart in a second direction that intersects with the first direction among directions that intersect with the vertical direction. According to this aspect, by providing a pair of connecting members, it is possible to separate a plurality of paths, such as wiring paths and piping paths, by type using the two connecting members. [Effects of the Invention]

[0014] According to each of the above aspects, infrastructure wires are not exposed in the spaces between fixtures, and maintenance work on the wiring and piping housed below the top plate can be easily performed. [Brief explanation of the drawings]

[0016] Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiments, identical or similar components will be assigned the same reference numerals, and redundant description may be omitted. In the following description, the normal direction of the floor surface F on which the work fixture 1 is installed will be referred to as the up-down direction (arrow UP indicates the up direction), and directions perpendicular to the up-down direction will be referred to as the front-rear direction (arrow FR indicates the forward direction) and the left-right direction (arrow LH indicates the left direction). In the following description, expressions indicating relative or absolute positions, such as "orthogonal" and "center," not only strictly refer to such positions, but also refer to a state in which there is a relative displacement with a tolerance or an angle or distance that provides the same function.

[0017] [Work Fixtures 1] FIG. 1 is a perspective view of the work fixture 1 seen from diagonally above the front. As shown in Figure 1, work fixture 1 is installed in facilities where experiments and research are conducted (for example, schools, offices, various research institutes, etc.). For example, by installing multiple work fixtures 1 in the same space of a facility, a fixture system is formed in which users can pass through the aisles formed between adjacent work fixtures 1 and use each work fixture 1. However, it is also possible to use just one work fixture 1.

[0018] The work fixture 1 comprises a first fixture unit (furniture with a top panel) 2, a second fixture unit (structure) 3, a first connecting member (connecting member) 4, and a second connecting member (connecting member) 5.

Specifically, the core member 10 includes a plurality of pillars (first pillars 20 and second pillars 21), duct members (horizontal members) 22, 23, bridging portions 24, 25, an attachment mechanism 26, and spacers 28, 29. The pillars 20, 21 are formed in a square tube shape and erected from positions spaced apart in the left-right direction (second direction) on the floor surface F. In the embodiment, a pair of pillars 20, 21 is illustrated as an example of multiple pillars, but the number of pillars is not limited to one pair. The first pillar 20 is configured by combining a pillar base 30 and a hub pillar 31 in the left-right direction.

[0021] FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIG. 4, the column base 30 is C-shaped in plan view, flattened in the left-right direction and opening outward in the left-right direction (the side away from the center of the work fixture 1). The column base 30 is in contact with the floor surface F via an adjuster or the like. The column base 30 forms part of the front wall and rear wall of the first column 20, as well as the left wall. A first groove 37 is formed in the front wall and rear wall of the column base 30. The first groove 37 extends linearly in the up-down direction.

[0022] FIG. 5 is a cross-sectional view taken along line VV in FIG. 5, the support base 30 is formed with wiring insertion openings (upper wiring insertion opening 35 and lower wiring insertion opening 36) that penetrate in the left-right direction. The upper wiring insertion opening 35 is formed in a portion of the support base 30 that is positioned above the center in the up-down direction. The lower wiring insertion opening 36 is formed in a portion of the support base 30 that is positioned below the center in the up-down direction.

[0023] The hub support 31 extends in the up-down direction along the support base 30 so as to contact the support base 30 from the outside in the left-right direction. The hub support 31 includes a wiring portion 31a and an extension portion 31b.

[0024] As shown in Fig. 4, the routing portion 31a is formed in a rectangular cylindrical shape in a plan view, with a width in the front-rear direction equal to that of the support base 30 and a width in the left-right direction wider than that of the support base 30. The routing portion 31a extends over the entire length of the support base 30 in the up-down direction. The routing portion 31a includes a hub base 33 and a cover panel 34. The inside of the routing portion 31a forms a first support insertion space S1 into which infrastructure lines (for example, wires L1 to L3 described below) can be inserted. In this embodiment, the first support insertion space S1 is formed over the entire length of the routing portion 31a in the up-down direction.

[0025] 5, the hub base 33 is formed with wiring outlets (upper wiring outlet 38 and lower wiring outlet 39) that penetrate in the left-right direction. The upper wiring outlet 38 is located at the same height as the above-mentioned upper wiring insertion opening 35. The lower wiring outlet 39 is located at the same height as the above-mentioned lower wiring insertion opening 36. The extension portion 31b is linearly connected to the routing portion 31a with its lower end edge abutting against the upper end edge of the routing portion 31a. The inside of the extension portion 31b defines an extension space S2 that communicates with the first support insertion space S1.

[0026] FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. As shown in Figure 6, the second support column 21 is formed in a rectangular cylindrical shape that is flatter in the left-right direction than the first support column 20. The second support column 21 is formed by combining a support column base 43 and a cover panel 44 in the left-right direction. The support column base 43 is in contact with the floor surface F via an adjuster or the like. Second grooves 45 are formed in the front and rear walls of the support column base 43. The second grooves 45 extend linearly in the up-down direction.

[0027] 5, wiring insertion openings (upper wiring insertion opening 47 and lower wiring insertion opening 48) that penetrate in the left-right direction are formed in the support base 43. The upper wiring insertion opening 47 is formed at the same height as the above-mentioned upper wiring insertion opening 35. The lower wiring insertion opening 48 is formed at the same height as the above-mentioned lower wiring insertion opening 36.

[0028] As shown in Fig. 6, the cover panel 44 covers the outside of the support base 43 in the left-right direction. In other words, the cover panel 44 forms the left wall of the second support 21. The cover panel 44 is detachably attached to the support base 43. The inside of the second support 21 forms a second support insertion space S3 into which an infrastructure cable can be inserted.

[0029] 5, of the duct members 22, 23, the first duct member 22 bridges the upper ends of the support bases 30, 43 of the respective supports 20, 21. The first duct member 22 includes a duct base 22a and a duct cover 22b. The duct base 22a is formed in a U-shape that opens upward when viewed in a cross section along the front-rear direction. The right end of the duct base 22a is fixed to the upper end of the first support column 20 by a screw, and the left end is fixed to the upper end of the second support column 21 by a screw.

[0030] The duct cover 22b is placed over the duct base 22a from above. Therefore, the first duct member 22 is formed in the shape of a rectangular tube that is flattened in the vertical direction. A first duct insertion space S4 is formed inside the first duct member 22, through which infrastructure cables and the like can be inserted. The first duct insertion space S4 communicates with the pillar insertion spaces S1 and S3 through cutouts 30a and 43a formed in the upper ends of the pillar bases 30 and 43, respectively.

[0031] Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 2. Fig. 8 is a cross-sectional view taken along line VIII-VIII in Fig. 2. 7 and 8, of the duct members 22 and 23, the second duct member 23 connects the support posts 20 and 21 at a height equivalent to that of the upper wiring insertion openings 35 and 47. The second duct member 23 is formed in a rectangular cylindrical shape. The inside of the second duct member 23 defines a second duct insertion space S5 into which infrastructure cables can be inserted through the wiring insertion openings 35 and 47.

[0032] As shown in Fig. 3, a connection portion 50 is provided on the front wall of the second duct member 23. The connection portion 50 is, for example, a receptacle for a power plug. The connection portions 50 are arranged at intervals in the left-right direction on the front wall of the second duct member 23. The receptacles of the connection portions 50 are open on the front wall of the second duct member 23. The connection portions 50 may also be receptacles for a USB (Universal Serial Bus) connector, a LAN (Local Area Network) connector, etc.

[0033] 3 and 7, in this embodiment, the bridging portions 24, 25 are the first bridging portion 24 and the second bridging portion 25. The first bridging portion 24 is installed between the supports 20, 21 above the lower wiring insertion openings 36, 48 and below the second duct member 23. The second bridging section 25 is installed between the support posts 20, 21 below the lower wiring insertion openings 36, 48. Therefore, the infrastructure cables drawn out through the lower wiring insertion openings 36, 48 can pass above the second bridging section 25. The second bridging section 25 has a plurality of through holes 52 (see FIG. 3) that penetrate in the vertical direction and are spaced apart in the horizontal direction. The positions and number of the duct members 22, 23 and the bridging sections 24, 25 can be changed as appropriate.

[0034] 3 and 4, the attachment mechanism 26 connects the columns 20, 21 to the functional component 11. The attachment mechanism 26 is provided on the front end of the right wall of the first column 20 and the front end of the left wall of the second column 21, respectively.

[0035] The attachment mechanism 26 includes a pair of upper stays 60 and a pair of lower stays 61 . The upper stay 60 is bent in a crank shape so as to protrude forward as it moves inward in the left-right direction. The base end (outer end in the left-right direction) of the upper stay 60 is fixed to the corresponding support pillars 20, 21 by, for example, screwing. The tip end (inner end in the left-right direction) of the upper stay 60 protrudes forward beyond the support pillars 20, 21.

[0036] The lower stay 61 is attached to the left wall of the first support pillar 20 and the right wall of the second support pillar 21 at portions located lower than the upper stay 60. The lower stay 61 is bent in a crank shape so as to protrude forward as it moves inward in the left-right direction. The base end of the lower stay 61 is fixed to the corresponding support pillars 20, 21 by, for example, screws. The tip end (the inner end in the left-right direction) of the lower stay 61 protrudes forward beyond the support pillars 20, 21.

[0037] 2 and 7, of the above-mentioned spacers 28, 29, the first spacer 28 bridges the portion of each of the pillars 20, 21 that is located below the first duct member 22 and above the second duct member 23. Of the above-mentioned spacers 28, 29, the second spacer 29 bridges the portion of each of the pillars 20, 21 that is located below the second duct member 23 and above the first bridging portion 24.

[0038] As shown in FIG. 5, in this embodiment, the infrastructure line includes a plurality of wirings (first wiring L1 to third wiring L3). Each of the wirings L1 to L3 is drawn downward from, for example, the ceiling surface of the facility, and then enters the core member 10 through the upper end opening of the extension portion 31b. The first wiring L1 passes through the extension portion 31b (extension space S2) and then extends downward through the routing portion 31a (first support insertion space S1). The first wiring L1 then enters the second duct member 23 (second duct insertion space S3) through the upper wiring draw-out opening 38 and the upper wiring insertion opening 35. A power strip 63 is provided at the tip of the first wiring L1. The power strip 63 is installed in the second duct member 23. A plurality of branch wirings 64 are connected to the power strip 63. Each of the branch wirings 64 is individually connected to the connection portion 50.

[0039] The second wiring L2 passes through the extension portion 31b (extension space S2), and then enters the second support 21 (second support insertion space S3) through the first duct member 22 (first duct insertion space S4). The second wiring L2 enters the second duct member 23 (second duct insertion space S5) through the wiring insertion port 47. A power strip 65 is provided at the tip of the second wiring L2. The power strip 65 is installed in the second duct member 23. A plurality of branch wirings 66 are connected to the power strip 65. Each branch wiring 66 is individually connected to the connection portion 50 described above.

[0040] The third wiring L3 passes through the extension portion 31b (extension space S2) and then extends downward within the routing portion 31a (first support insertion space S1). The third wiring L3 is then drawn out onto the second bridge portion 25 through the lower wiring outlet 39 and the lower wiring insertion port 36. A power strip 67 is provided at the tip of the third wiring L3. The power strip 67 is installed on the second bridge portion 25. In this embodiment, the infrastructure lines L1 to L3 may be various types of wiring such as power lines and information lines, as well as various types of piping such as water pipes and gas pipes.

[0041] <Functional Component 11> 2 and 7, the functional component 11 is detachably attached to the front side of the core member 10. The functional component 11 is, for example, a laboratory table (desk) with a liftable top. The functional component 11 includes a support structure 71 and a top 72. The support structure 71 is formed in a C-shape that opens forward in a plan view. Specifically, the support structure 71 includes a pair of left and right side curtain boards 73, a rear curtain board 74, and lifting legs 75.

[0042] The side curtain boards 73 are formed in a box shape with the thickness direction being the left-right direction. The upper end surface of each side curtain board 73 is set at the same height as the first bridging portion 24. Of each side curtain board 73, one side curtain board 73 faces the first support post 20 in the front-to-rear direction, and the other side curtain board 73 faces the second support post 21 in the front-to-rear direction.

[0043] The rear curtain board 74 connects the rear ends of the side curtain boards 73. The rear curtain board 74 is fixed to the core member 10 via the above-mentioned mounting mechanism 26. Specifically, the rear curtain board 74 is fixed to the core member 10 by screwing the tip ends of each stay 60, 61 to the rear curtain board 74.

[0044] As shown in Figures 2 and 7, the rear panel 74 has an insertion hole 76 formed in a portion located above the upper surface of the second bridge portion 25 described above, which penetrates the rear panel 74 in the front-to-rear direction. The lifting legs 75 are comprised of a plurality of square tubes with different outer shapes in a plan view. The lifting legs 75 are configured to be housed inside the square tube with the larger outer shape in a plan view among the square tubes described above. The lifting legs 75 are configured to be extendable and retractable in the vertical direction as each square tube moves relative to the others in the vertical direction through the operation of a drive mechanism (not shown). The lifting legs 75 are housed in the front end of the side curtain board 73 in a state where they protrude upward. The wiring drawn from the drive mechanism is routed above the second bridge section 25, for example, through an insertion port 76, and then connected to a power strip 67.

[0045] The top plate 72 spans between the upper ends (the rectangular tubes with the smallest outer dimensions in plan view) of the lifting legs 75. The top plate 72 is configured to be movable up and down as the lifting legs 75 extend and retract. The top plate 72 is located midway between the first support pillar 20 and the second support pillar 21 of the core member 10 in the up and down direction. In other words, the support pillars 20, 21 protrude above the top plate 72 even when the top plate 72 is at its uppermost position.

[0046] <Shelf 13, 14> The upper shelf 13 is provided in a state of protruding forward in a portion of each core member 10 that is located above the second duct member 23. The upper shelf 13 is fixed at both left and right ends to the corresponding support posts 20, 21 by, for example, engaging with claws or screws. As a result, the upper shelf 13 is supported by the core member 10 while spanning the support posts 20, 21. In this embodiment, it is preferable that the upper surface of the upper shelf 13 is set flush with the upper surface of the first spacer 28 described above. As a result, the upper surfaces of the pair of front and rear upper shelf plates 13 are connected together via the upper surfaces of the first spacers 28.

[0047] The lower shelf 14 is provided in the core member 10 at a position equivalent to that of the second duct member 23, protruding forward. The lower shelf 14 is fixed at both left and right ends to the corresponding support posts 20, 21 by, for example, engaging with claws or screws. As a result, the lower shelf 14 is supported by the core member 10 while spanning the support posts 20, 21. In this embodiment, it is preferable that the upper surface of the lower shelf 14 is set flush with the upper surface of the second duct member 23. As a result, the upper surfaces of the pair of front and rear lower shelf plates 14 are connected together via the upper surfaces of the second duct members 23.

[0048] <Panel Unit 15> As shown in FIGS. 1 and 5 , a decorative panel unit (panel member) 15 is detachably attached to the rear side of the core member 10. The panel unit 15 is attached to the rear side of the core member 10, thereby covering a lower space (storage space) 98 and an upper space 99 below the top plate 72 from behind. The lower space 98 is a space in the core member 10 that is located below the top plate 72. That is, in this embodiment, the lower space 98 is a space in the core member 10 that is surrounded by the support posts 20, 21 and the second spacer 29, and accommodates wiring L3, a power strip 67, etc. The lower space 98 may also be connected to the lower side of the top plate 72.

[0049] On the other hand, the upper space 99 is a space located above the top plate 72 in the core member 10. That is, the upper space 99 is a space surrounded by the supports 20, 21, the first duct member, and the second spacer 29 of the core member 10, and accommodates the wiring L1, L2, the table taps 63, 65, etc. The upper space 99 is in communication with the spaces above the shelves 13 and the space below the lower shelf 14.

[0050] FIG. 9 is an exploded perspective view of the work fixture 1 as seen obliquely from above and behind. As shown in FIGS. 4, 6, and 9, the panel unit 15 includes a first panel member 101 and a second panel member (upper panel member) 102. The first panel member 101 is formed in a rectangular plate shape with its thickness in the front-to-rear direction so as to correspond to the space 98 below the top plate 72, and its right end 101a and left end 101b are bent forward. The right end 101a and left end 101b are inserted into the corresponding first groove 37 and second groove 45 from the rear, and are fixed to the supports 20, 21 by engagement with screws, claws, etc. within the first groove 37 and second groove 45. In this way, the first panel member 101 is detachably attached to the core member 10 from the rear (the passage space 7 side).

[0051] By attaching the first panel member 101 to the lower parts of the first support column 20 and the second support column 21, the lower space 98 is closed off from the passage space 7 side. In other words, when attached to the core member 10, the first panel member 101 blocks communication between the lower space 98 and the passage space 7. In this state, for example, the third wiring L3 and the table tap 67 (see FIG. 5 ) housed in the lower space 98 are not visible from the passage space 7. By removing the first panel member 101 from the first support column 20 and the second support column 21, the lower space 98 is opened toward the passage space 7.

[0052] The second panel member 102 has a thickness in the front-to-rear direction and is formed in a rectangular plate shape to correspond to the space 99 above the top plate 72. The right end 102a and the left end 102b are bent forward. The right end 102a and the left end 102b are inserted from the rear into the corresponding first groove 37 and second groove 45 above the first panel member 101 and are fixed to the support columns 20, 21 by fastening with screws or nails within the first groove 37 and the second groove 45. This allows the second panel member 102 to be detachably attached to the core member 10 from the rear (the passage space 7 side). In this embodiment, it is preferable that the first panel member 101 and the second panel member 102 are integrally connected in the vertical direction and that their rear surfaces are flush with each other. It is also preferable that each panel member 101, 102 smoothly connects with the rear surfaces of the support columns 20, 21.

[0053] The second panel member 102 is attached to the top of the first support column 20 and the second support column 21, thereby closing off the upper space 99 from the rear (the passage space 7 side). When attached to the core member 10, the second panel member 102 blocks communication between the upper space 99 and the passage space 7. In this state, for example, the first wiring L1, the multiple branch wirings 64, the second wiring L2, the multiple branch wirings 66, the table taps 63, 65, etc. housed in the upper space 99 are not visible from the passage space 7. When the second panel member 102 is removed from the first support column 20 and the second support column 21, the upper space 99 is opened toward the passage space 7.

[0054] In this embodiment, an example will be described in which the entire first panel member 101 and the entire second panel member 102 are removed from the first support pillar 20 and the second support pillar 21 to open the lower space 98 and the upper space 99, respectively, but this is not limiting. As another example, for example, the first panel member 101 and the second panel member 102 may be provided with small openable and closable windows that allow access to the corresponding spaces 98, 99, respectively.

[0055] [Second Fixture Unit 3] As shown in Figure 9, the second fixture unit 3 is arranged facing the first fixture unit 2 in the front-to-rear direction, with the aisle space 7 in between. Of the components of the second fixture unit 3, the components corresponding to those of the first fixture unit 2 are given the same reference numerals as those of the first fixture unit 2, and detailed explanations will be omitted.

[0056] The second furniture unit 3 is installed on the opposite side of the core member 10 of the first furniture unit 2 from the top plate 72 side (i.e., the rear side of the first furniture unit 2) at a distance L in the front-to-rear direction from the first furniture unit 2. The functional component 12 in the second furniture unit 3 is, for example, a laboratory table (desk) with a fixed top plate. The functional component 12 includes a support structure 81 and a top plate 82. The support structure 81 is formed in a C-shape that opens rearward in a plan view. The support structure 81 is fixed to the core member 10 via the attachment mechanism 26 described above, for example.

[0057] [Connecting material 4,5] FIG. 10 is a perspective view of the second connecting member 5 disassembled from the first duct member 22. As shown in FIG. As shown in Figures 5, 9 and 10, the first connecting member 4 and the second connecting member 5 are members that span the first furniture unit 2 and the second furniture unit 3, thereby connecting the furniture units 2, 3 at a distance L in the front-to-rear direction. The first connecting member 4 and the second connecting member 5 are members that have roughly the same configuration, and the constituent members of the first connecting member 4 and the second connecting member 5 are given the same reference numerals, and a detailed description of the first connecting member 4 will be omitted.

[0058] The second connecting member 5 includes a connecting base (receiving portion) 105 and a connecting cover (cover member) 106. The connecting base 105 has front and rear ends 105a, 105b fixed to the left end of the first duct member 22 (specifically, duct base 22a) of the furniture units 2, 3 with screws 108. In other words, the connecting base 105 is connected to the upper end of the right side of the furniture units 2, 3. The thickness direction of the connecting base 105 is the vertical direction, and a pair of base pieces 105c protrude upward from both the left and right sides to form an opening 109 for accommodating infrastructure lines such as wiring and piping. The thickness direction of the connecting cover 106 is the vertical direction, and a pair of cover pieces 106a protrude downward from both sides.

[0059] A connecting cover 106 is attached to the connecting base 105 from above, with a pair of cover pieces 106a overlapping a pair of base pieces 105c in the left-right direction. As a result, the opening 109 of the connecting base 105 is covered by the connecting cover 106. Therefore, the first connecting member 4 is formed in the shape of a rectangular tube that is flattened in the vertical direction. An insertion space S6 is formed inside the first connecting member 4, through which an infrastructure cable can be inserted. The insertion space S6 is connected to the first duct insertion space S4 of the first furniture unit 2 and the support insertion spaces S1, S3, etc. through the upper end of the support base 30.

[0060] Like the second connecting member 5, the first connecting member 4 includes a connecting base 105 and a connecting cover 106. The connecting base 105 has front and rear ends 105a, 105b fixed to the right end of the first duct member 22 (specifically, duct base 22a) of the furniture units 2, 3 with screws (not shown). In other words, the connecting base 105 is connected to the upper end of the right side of the furniture units 2, 3. An insertion space S7 into which infrastructure cables or the like can be inserted is formed inside the first connecting member 4. The insertion space S7 communicates with the pillar insertion spaces S1, S3, etc. through the upper end of the pillar base 30.

[0061] As described above, according to the work fixture 1 of the embodiment, the space 98 below and the space 99 above the top plate 72 provided in the first fixture unit 2 are covered with the panel unit 15. In addition, the space 98 below and the space 99 above the top plate 72 provided in the second fixture unit 3 are covered with the panel unit 15. Therefore, infrastructure wiring for, for example, laboratory equipment or measuring equipment, can be prevented from being exposed in the aisle space 7 from the space 98 below and the space 99 above each fixture unit 2, 3. This improves the aesthetic appearance of the fixture units 2, 3 as viewed from the aisle space 7, and allows the aisle space 7 to be used as a passageway through which users can pass.

[0062] Furthermore, by removing the panel unit 15 from the core member 10, the passage space 7 can be connected to the lower space 98 and the upper space 99. That is, by removing the first panel member 101 and the second panel member 102 from the core member 10, the lower space 98 and the upper space 99 can be opened toward the passage space 7. This makes it possible to access the lower space 98 and the upper space 99 from the passage space 7, facilitating work such as maintenance of infrastructure lines arranged in the lower space 98 and the upper space 99.

[0063] Furthermore, by closing the upper space 99 with the second panel member 102, the space above the shelves 13, 14 is blocked from the passage space 7. Therefore, the second panel member 102 can prevent items placed on the shelves 13, 14 from falling into the passage space 7.

[0064] Furthermore, the first panel member 101 and the second panel member 102 are detachably attached to the support posts 20, 21. This allows the first panel member 101 and the second panel member 102 to be removed from the core member 10 during work such as infrastructure line maintenance, so that the first panel member 101 and the second panel member 102 do not get in the way when accessing the lower space 98 and the upper space 99.

[0065] Furthermore, a first bridging section 24, a second bridging section 25, a first duct member 22, and a second duct member 23 are installed between the first support column 20 and the second support column 21. This allows the support columns 20, 21, the bridging sections 24, 25, and the duct members 22, 23 to be used as paths for infrastructure lines, making it easier to lay out infrastructure lines. In addition, the strength of the first furniture unit 2 and the second furniture unit 3 can be ensured.

[0066] Furthermore, by connecting the upper ends of the first fixture unit 2 and the second fixture unit 3 with the connecting members 4, 5, the connecting members 4, 5 can be provided above the aisle space 7. This prevents the connecting members 4, 5 from getting in the way when the aisle space 7 is used as a general aisle. Here, for example, it is also possible to connect the lower ends of the first fixture unit 2 and the second fixture unit 3 with the connecting members 4, 5 and place the connecting members 4, 5 along the floor surface F. In this case as well, the connecting members 4, 5 can be kept out of the way to some extent when the aisle space 7 is used as a general aisle.

[0067] Furthermore, openings 108 of the connecting members 4 and 5, through which infrastructure lines are inserted, are covered with connecting covers 106. This allows the infrastructure lines passed through the connecting members 4 and 5 to be securely held by the connecting covers 106. Furthermore, by connecting the first fixture unit 2 and the second fixture unit 3 with connecting members 4, 5, multiple paths, such as wiring paths and piping paths, can be divided by type using the two connecting members 4, 5.

[0068] In the embodiment, the second fixture unit 3 has been described as an example of a structure. By using the second fixture unit 3 as the structure, the work fixture 1 can be provided with two fixtures: the first fixture unit 2 and the second fixture unit 3. In this case, the top plates 72, 82 of the fixture units 2, 3 each protrude away from the aisle space 7, so that the work fixture 1 can be provided with excellent usability. In this embodiment, the first fixture unit 2 and the second fixture unit 3 can be assembled simply by varying the mounting positions of the functional components 11, 12 and the panel unit 15 on the same core member 10. That is, in the first fixture unit 2, the functional component 11 is mounted on the front side of the core member 10, and the panel unit 15 is mounted on the rear side of the core member 10. On the other hand, in the second fixture unit 3, the panel unit 15 is mounted on the front side of the core member 10, and the functional component 12 is mounted on the rear side of the core member 10. This makes it possible to provide work fixture 1 at low cost and with improved ease of assembly.

[0069] Although the embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment. Addition, omission, substitution, and other modifications of the configuration are possible within the scope of the gist of the present invention. For example, in the embodiment, the configuration in which each of the furniture units 2 and 3 includes a furniture with a tabletop as the functional components 11 and 12 has been described, but this configuration is not limiting. As for the functional components 11 and 12, it is sufficient that at least the functional component 11 of the first furniture unit 2 is a furniture with a tabletop, and the functional component 12 of the second furniture unit 3 may be a sofa or the like in addition to a furniture with a tabletop. Furthermore, the functional components may be, for example, shelves, drawers, sinks, displays, etc. In this way, the functional components may be tabletop fixtures with upward-facing work surfaces such as shelves, workbench tops 72, 82, sinks, etc., or may be items with load-bearing surfaces such as various tabletops of tabletop fixtures or sofa seats.

[0070] In the above-described embodiment, the second furniture unit 3 is used as an example of the structure connected to the first furniture unit 2 by the connecting members 4 and 5, but the present invention is not limited to this configuration.
