  However, the following problems still remain in the experimental bench described in Patent Document 4. That is, wiring such as a power supply line to which power is supplied and piping through which fluid and gas flow are arranged in the same space in almost all regions without being particularly divided. Therefore, it is not preferable for safety when a problem such as electric leakage or gas leakage occurs. Also, when wiring is performed, unlike wiring that can be relatively freely arranged, the piping is not very flexible and difficult to handle. For this reason, it is desirable to carry out the piping work in a dedicated space separated from the wiring, but no such consideration is made. Therefore, there was a problem that workability was poor.

  The present invention has been made in view of such circumstances, and the purpose of the present invention is to have a high proportion of wiring and piping arranged in separate spaces, ensuring high safety, and arranging work. It is to provide a working fixture that is easy to perform.

  In order to solve the above-mentioned problems, according to the first embodiment of the present invention, a working fixture in which wiring and piping are arranged, arranged spaced apart from each other in the left-right direction and erected on the floor surface. A pair of supporting columns, a work top plate provided between the pair of supporting columns, and a horizontal inner space that is fixed between the pair of supporting columns and that can take out at least one of wiring and piping to the outside. The column has a hollow column body in which a space extending in the vertical direction is formed inside, and is detachably fixed to a side surface of the column body, and extends in the vertical direction between the column body. A cover member that forms an existing space, the support column body is formed with a communication hole that penetrates the support column body from side to side, an internal space of the lateral connection member through the communication hole, a space of the support column body, The space formed by the cover member communicates with each other.

  According to the second aspect of the present invention, it is a working fixture in which wiring and piping are arranged, and is arranged apart from each other in the left-right direction with the inner surface facing each other, and is erected on the floor surface. A plurality of hollow shapes that are fixed between the pair of support columns and at least one of the wiring and the piping can be taken out to the outside. A horizontal support member, and a support column that is detachably fixed to the outer surface of the support column body and a hollow support column body in which a wiring installation space extending in the vertical direction is formed. And a cover member for forming a piping arrangement space extending in the vertical direction between the main body and the main body, the inner surface and the outer surface are communicated with the main body through the left and right. A communication hole is formed, and through the communication hole, the internal space of the horizontal connecting member and the wiring arrangement space And between the tubes for disposing space are communicated with each.

  In the work fixture according to the present invention, when performing an experiment or the like on the top plate, the wiring such as the power supply line and the signal line from the horizontal connecting member fixed between the pair of support columns, and the fluid such as cold water And a pipe through which a gas such as a gas flows can be easily taken out. Therefore, a power line, a signal line, cold water, gas, or the like can be easily used as needed during work. Therefore, it is easy to use and efficient work can be performed.

  By the way, the wiring such as the power supply line and the piping for supplying fluid and gas are arranged from the support column to the internal space of the horizontal connecting member and then taken out of the horizontal connecting member. More specifically, wiring is first arranged from the ceiling or under the floor to the vicinity of the connection point of the horizontal connection member through the wiring arrangement space formed inside the column main body constituting the column. On the other hand, the piping is arranged from the ceiling or under the floor to the vicinity of the connection point of the horizontal connection member through the piping installation space formed between the cover member constituting the support column and the support column main body. And these wiring and piping are arrange | positioned so that it may be drawn out to the internal space of a horizontal connection member through the communicating hole formed in the support | pillar main body. Thereafter, the wiring and piping are drawn out to the outside of the lateral connecting member and used.

  In particular, the wiring and the piping are separately disposed in two spaces, that is, a wiring disposition space and a piping disposition space, until the wiring and the piping are pulled out to the horizontal connecting member. Therefore, unlike the conventional case where the wiring and the piping are disposed in substantially the same space, it is possible to increase the ratio of being disposed in separate spaces. Therefore, it is possible to reduce the danger when a malfunction such as electric leakage or gas leakage occurs, and to provide a highly safe fixture. In addition, the piping that is difficult to dispose compared to the wiring is disposed in a space (arrangement space for piping) formed between the column main body and the cover member. Therefore, piping can be exposed to the side of a fixture by removing a cover member from a support | pillar main body. Therefore, piping can be arranged in a wide work area, and workability can be greatly improved.

  Among the plurality of horizontal coupling members, the internal space of one horizontal coupling member is used as a wiring-dedicated arrangement space in which wiring is drawn out from the wiring arrangement space, and the other one horizontal coupling member The internal space may be used as an installation space dedicated for piping in which piping is drawn out from the piping installation space.

  In the working fixture according to the present invention, the wiring and the piping are not arranged at the same time in the internal space of the common horizontal connecting member from the column side, but the wiring and the piping are respectively provided in the internal space of the separate horizontal connecting members.

Therefore, it is possible to further reduce the danger when electric leakage or gas leakage occurs, and it is possible to provide a fixture with higher safety.

  The horizontal connecting member is provided with a partition member that divides the internal space into a first internal space and a second internal space, and wiring is provided by being drawn from the wiring installation space to the first internal space. The piping may be arranged by being drawn out from the piping installation space to the second internal space.

  In the working fixture according to the present invention, the internal space of the horizontal connecting member is divided into a first internal space and a second internal space by the partition member. Therefore, the wiring can be drawn out and arranged in the first internal space from the column side, and the piping can be drawn out and arranged in the second internal space. Thus, even if a common horizontal connecting member is used, the wiring and the piping can be arranged in separate spaces. Therefore, it is possible to further reduce the danger when electric leakage or gas leakage occurs, and it is possible to provide a fixture with higher safety.

  A groove portion that is recessed inward from the inner surface in the vertical direction may be formed in the column main body, and a space in the groove portion may be used as a wiring arrangement space.

  In the working fixture according to the present invention, a groove portion that is recessed in the vertical direction is formed on the inner surface of the column main body, and the space in this groove portion can be used as a wiring arrangement space. Therefore, when performing the wiring arrangement work, it is possible to perform the simple work of simply arranging the wiring in the groove. Accordingly, it is possible to improve the arrangement workability with respect to the wiring.

  A closing member that closes the opening of the groove may be provided.

In the present embodiment, as shown in FIG. 15, the duct device 5 is fixed at the middle position P2.

Further, as shown in FIGS. 12 and 13, the communication hole 20d on the column main body 20 side and the entrance / exit 5a on the duct device 5 side are formed in a vertically long shape extending in the vertical direction. As shown in FIG. 16, no matter what position the duct device 5 is changed to, the communication hole 20d and the entrance / exit 5a are always overlapped. 14 to 16, the hatched area S is an area where the communication hole 20d and the entrance / exit 5a overlap.
Therefore, the communication hole 20d and the entrance / exit 5a can always be communicated regardless of the fixed position of the duct device 5, and the wiring L1 and the pipe L2 can be drawn into the internal space. That is, it is designed so as not to affect the arrangement of the infrastructure line L.

  Further, as shown in FIGS. 12 and 13, a lid plate 15 having an outlet 15 a through which the wiring L <b> 1 drawn inside can be taken out is detachably fitted on the upper surface of the duct device 5. The outlets 15a are formed at two places in the front-rear direction, and are formed along the longitudinal direction of the duct device 5, respectively. These outlets 15a are covered with innumerable soft wires 35, and are designed so that the internal space of the duct device 5 cannot be seen from the outside. However, when necessary, it is possible to scrape the soft wire 35 and take out the wiring L1.

  In this embodiment, since the upper surface of the lid plate 15 and the upper surface of the top plate 3 are substantially flush as described above, the lid plate 15 is taken out from the duct device 5 through the outlet 15a as shown in FIG. Various wirings L1 can be immediately drawn on the top plate 3 for use. In FIG. 17, as an example of the wiring L1, a power supply line connected to an outlet is illustrated as an example.

In this embodiment, as shown in FIG. 1, the cover member 21 is fixed to the column body 20 of one column 2, but the cover member 21 is fixed to the column body 20 of the other column 2. The case is not taken as an example. Further, with respect to the other experimental table 1 arranged side by side with one experimental table 1, the case where the cover member 21 is not fixed to any of the pair of columns 2 is taken as an example. However, the present invention is not limited to this case, and the cover member 21 may be fixed to any column body 20. Whether or not the cover member 21 is fixed may be determined by whether or not the pipe L2 is provided along the support column 2.

  Here, the arrangement route of the infrastructure line L (wiring L1 and piping L2) of this embodiment is demonstrated easily. As shown in FIG. 3, first, the wiring L <b> 1 and the pipe L <b> 2 drawn from the ceiling are disposed on one support column 2 of one experimental bench 1. At this time, as shown in FIG. 6, the wiring L1 is arranged in the wiring arrangement space E1 in the groove portion 22, and the piping L2 is arranged in the piping arrangement space between the column main body 20 and the cover member 21. It is arranged at E2.

  Then, as shown in FIG. 3, the wiring L1 arranged in the wiring arrangement space E1 is branched into two after being drawn out by the upper beam 6, and the wiring arrangement space E1 on the other support column 2 side. The remaining branch is disposed in the wiring space E1 of the other column 2 via the upper beam 6 of the other experimental table 1. And the wiring L1 arrange | positioned in each wiring arrangement | positioning space E1 branches into two again in the middle, and is drawn out and arrange | positioned by the utility beam 4, and the remainder which branched is the duct apparatus 5 It is pulled out and arranged. The wiring L1 disposed on the utility beam 4 is connected to the power connector 4a. On the other hand, the wiring L1 disposed in the duct device 5 is used by being drawn out on the top plate 3 through the outlet 15a. A part of the extracted wiring L1 is connected to an outlet or the like as shown in FIG.

  Further, as shown in FIG. 3, the pipe L2 arranged in the pipe arrangement space E2 passes through the communication hole 20c formed in the column main body 20, and then passes through the wiring arrangement space E1 to enter the utility. It is disposed in the internal space of the beam 4. Then, after branching into two, it is connected to the bulb 4b of the utility beam 4. On the other hand, the remaining branched pipe L <b> 2 is disposed in the internal space of the utility beam 4 of the other experimental bench 1 and then connected to the valve 4 b of the beam 4.

  Next, a case where an experiment work is performed using the experimental bench 1 configured as described above will be described. First, as shown in FIG. 1, the top plate 3 serving as a work plane is fixed in the front-rear direction, so that an operator can efficiently perform an experimental work in a wide face-to-face work area. In addition, when performing the experimental work, electric power is used via the power supply connector 4a provided on the utility beam 4, and various fluids such as cold water and hot water and various gases such as gas are used via the valve 4b. can do. As described above, since electric power, water, gas, and the like can be easily used as necessary, efficient experimental work can be performed. In addition to the utility beam 4, as shown in FIG. 17, the wiring L1 can be drawn out on the top plate 3 from the outlet 15a of the duct device 5 and used as a power line or the like, which is very convenient. It is easy to carry out experimental work.

  In particular, according to the experimental bench 1 of the present embodiment, as shown in FIGS. 3 and 6, the wiring L1 and the piping L2 are connected to the wiring placement space E1 and the piping placement space E2 in one support column 2. It is arranged separately in one space. Therefore, unlike the conventional case where the wiring L1 and the pipe L2 are disposed in substantially the same space, the ratio of being disposed in separate spaces can be increased. Therefore, it is possible to reduce the danger when a malfunction such as electric leakage or gas leakage occurs, and to provide a highly safe fixture.

  In addition, the pipe L2 that is difficult to arrange as compared with the wiring L1 is arranged in the space formed between the column main body 20 and the cover member 21, that is, the pipe arrangement space E2. Therefore, the pipe L <b> 2 can be exposed to the side of the experimental bench 1 by removing the cover member 21 from the column main body 20. Therefore, the piping L2 can be disposed in a wide work area, and workability can be significantly improved.

  Furthermore, the space of the groove 22 formed in the inner surface of the column main body 20 is defined as a wiring arrangement space E1. Therefore, when the wiring L1 is disposed, the work can be performed simply by arranging the wiring L1 in the groove portion 22. Therefore, the arrangement workability can also be improved with respect to the wiring L1. Further, since the opening of the groove portion 22 is closed using the closing member 24 of the channel member 23, the wiring L1 disposed in the groove portion 22 can be prevented from being constantly exposed. Therefore, the appearance and appearance can be improved, and a high-quality fixture can be obtained. Moreover, the closing member 24 is a flexible member, and the other end is a free end. Therefore, the wiring L1 disposed in the groove portion 22 can be easily taken in and out by a simple act of simply deforming the closing member 24 without removing it. Therefore, the installation workability can be further improved, and it is possible to quickly cope with troubles on wiring, maintenance, and the like.

  Further, when the wiring L1 and the pipe L2 are disposed in the utility beam 4, the lower surface plate 4d, which is a decorative member, can be removed. Therefore, the arrangement workability can be easily and reliably performed in this respect. With respect to the duct device 5 as well, the lid plate 15 on the upper surface can be removed, so that the arrangement work can be easily and reliably performed.

  By the way, when performing the experimental work, the height of the duct device 5 and the top board 3 depends on the posture of the worker (for example, the posture while standing or sitting on a chair) and the physique such as extension. Can be changed. For example, as shown in FIG. 14, the position of the duct device 5 may be changed from the middle position P2 to the low position P1 close to the floor surface F, and the position of the top plate 3 may be lowered accordingly. On the contrary, as shown in FIG. 16, the position of the duct device 5 may be changed from the middle position P2 to the high position P3 close to the ceiling, and the position of the top plate 3 may be raised accordingly. . Thus, since the height of the duct apparatus 5 and the top plate 3 can be changed, it is possible to prepare an optimum experimental environment that matches the posture and physique of the worker. Therefore, in this respect, it is possible to perform an experimental work that is very convenient and efficient.

  In addition, the position of the outlet 15a provided on the upper surface of the duct device 5 and the position of the upper surface of the top plate 3 can be set at different heights. For example, as shown in FIG. 18, among the top plates 3 that are back-to-back in the front-rear direction, only one top plate 3 is positioned below the upper surface of the lid plate 15 provided with the outlet 15a. As shown in FIG. 19, both the top plates 3 may be fixed so as to be positioned below the lid plate 15 provided with the outlet 15a. Furthermore, as shown in FIG. 20, you may fix both the top plates 3 so that it may be located above the cover plate 15 in which the exit 15a was provided.

  In this way, by setting the position of the outlet 15a provided on the upper surface of the duct device 5 and the position of the upper surface of the top plate 3 to different heights, a height gap is positively established between the two. Can be produced. Depending on the content of the experimental work, there are many cases where it is preferable to arrange the outlet 15a above or below the experimental equipment placed on the top 3, and the positional relationship between the outlet 15a and the top 3 is necessary. There is a need to change it according to the situation. According to the experimental bench 1 of the present embodiment, it is possible to meet such needs, so that it is very easy to use.

  In the first embodiment, only the wiring L1 is drawn into the duct device 5 and the internal space in the duct device 5 is used as a dedicated space for the wiring L1. However, the pipe L2 may be drawn. In this case, since it is possible to draw the pipe L2 from the duct device 5 through the outlet 15a to the top plate 3 in addition to the wiring L1, the usability is further improved and the working efficiency is improved. it can.

  In the first embodiment, the power connector 4a and the valve 4b are provided on the utility beam 4. However, only the valve 4b may be provided on the utility beam 4. In this case, since only the pipe L2 is disposed in the utility beam 4, the internal space of the utility beam 4 is used as a dedicated space for the pipe L2. By doing so, the pipe L2 can be arranged only in the utility beam 4 and the wiring L1 can be arranged only in the duct device 5. That is, the internal space in the utility beam 4 that is one of the horizontal connection members can be used as an arrangement space dedicated to the pipe L2, and the internal space in the duct device 5 that is one of the horizontal connection members is allocated to the wiring L1. It can be used as an installation space. Accordingly, the wiring L1 and the pipe L2 can be arranged not only in the support column 2 but also in different spaces after being pulled out of the support column 2. Therefore, even if a problem such as electric leakage or gas leakage occurs, the danger can be further reduced and the safety can be further increased. Therefore, it can be set as the reliable reliable test bench 1.

  Next, a second embodiment according to the present invention will be described with reference to FIG. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The difference between the second embodiment and the first embodiment is that the internal space in the utility beam is divided into a first internal space X1 and a second internal space X2.

  That is, in the utility beam (lateral connecting member) 40 of this embodiment, as shown in FIG. 21, the internal space is physically divided into the first internal space X1 and the second internal space X2 by the partition member 41. ing. In FIG. 21, only the partition member 41 provided on one of the front and rear surfaces of the utility beam 40 is illustrated. The partition member 41 is an angle member having an L-shaped cross section, and is provided on the front and rear surfaces in the utility beam 40 in the left-right direction. Thereby, the wiring L1 drawn into the utility beam 40 can be disposed up to the power connector 4a through the first internal space X1 partitioned by the partition member 41. On the other hand, the pipe L2 drawn into the utility beam 40 is disposed up to the valve 4b through the second internal space X2 physically separated from the first internal space X1 by the partition member 41.

  Thus, according to this embodiment, even if the wiring L1 and the pipe L2 are simultaneously drawn into the utility beam 40, the wiring L1 and the pipe L2 can be arranged in different spaces. Therefore, even if a problem such as electric leakage or gas leakage occurs, the danger can be further reduced and the safety can be further increased. Therefore, it can be set as the reliable reliable test bench 1. In addition, the other effect can show the effect similar to 1st Embodiment. In addition, as shown in FIG. 22, even if it provides the partition member 41 in the approximate center so that the utility beam 40 may be divided into right and left, there can exist the same effect.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the case where two experimental benches 1 are arranged in the left-right direction has been described as an example. However, one or three or more experimental benches may be arranged in parallel. Moreover, although the case where the top plate 3 is fixed back to back in the front-rear direction is taken as an example, the top plate 3 may be fixed only on one side. Moreover, although the case where the utility beam 4 and the duct apparatus 5 were fixed between a pair of support | pillars 2 was demonstrated to the example, you may fix only either one. You may change suitably according to the installation environment which installs the experiment stand 1. FIG. Further, using the engagement holes 20 a provided in the column main bodies 20 of the pair of columns 2, shelves for mounting various experimental devices, storage boxes, lighting fixtures, and the like are placed between the pair of columns 2. You can fix it.
