Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. It should be noted that in the embodiments, the drawings schematically show the outline of the invention, and it should be noted that they are different from the actual ones.

[0012] <One Embodiment> FIG. 1 is a perspective view showing a schematic configuration of a laboratory bench 1 according to one embodiment, FIG. 2 is a front view of the laboratory bench 1, and FIG. 3 is a side view of the laboratory bench 1 shown from the side of a lift-type storage cabinet (down cabinet) 50. FIG. 4 is a cross-sectional view of the laboratory bench 1 taken along line IV-IV of FIG. 2.

[0013] The laboratory bench 1 according to the present embodiment is a laboratory bench equipped with a swing-type lift-type storage cabinet 50, and has a structure that allows a user (operator) to take in and out equipment stored in the lift-type storage cabinet 50 without using a step ladder or the like while remaining in a substantially working posture.

[0014] That is, as shown in FIGS. 1 to 4, for example, the laboratory bench 1 includes a workbench 10 as a work table on which a user performs operations such as experiments and inspections, and a storage shelf 20 arranged at the upper rear of the workbench 10 for storing various equipment used in the work. The various equipment stored in the storage shelf 20 includes, for example, experimental instruments, inspection equipment, or chemicals such as reagents used in the work.

[0015] Here, as an example of the system, the laboratory bench 1 including the storage shelf 20 and the workbench 10 arranged in front of the storage shelf 20 is configured to be arranged face-to-face such that the workbenches 10 are line-symmetric on both sides of the storage shelf 20, and a shared sink 30 is provided.

[0016] Since each laboratory bench 1 with the storage shelf 20 as the center has the same structure including the workbench 10 and the storage shelf 20, hereinafter, mainly one (for example, the front side) of the laboratory benches 1 will be described.

[0017] In the laboratory bench 1, the workbench 10 includes, for example, a plurality (here, four) of drawers 12 and movable side tables (cabinet wagons) 14 and 15 arranged below the drawers 12, and allows work to be performed while sitting on a chair (not shown).

[0018] The storage shelf 20 includes, for example, two sturdy steel shelf frames (bridge structures) 40 arranged in the left-right (arrow X in the figure) direction, a liftable storage cabinet 50 disposed on one side of the shelf frame 40, a storage shelf 60, and a storage rack 70 disposed on the other side of the shelf frame 40.

[0019] The shelf frame 40 is composed of a pair of columns, namely, a connecting pillar (extension pillar) 42 connected to the support pillar 41, and a first erection part 43 and a second erection part 44 erected between the connecting pillars 42.

[0020] Here, the support pillar 41 connects the workbenches 10 to each other and enables the addition of the storage shelf 20 by retrofitting the shelf frame 40. That is, the support pillar 41 is, for example, at the rear of the workbench 10 (in the direction of arrow Y in the figure), and is firmly attached and fixed to the vicinity of both the left and right ends and the vicinity of the center on the back end side of the worktable surface SF over substantially the entire length in the vertical direction (arrow Z in the figure) of the workbench 10.

[0021] Therefore, by firmly connecting the connecting pillar 42 to the support pillar 41 so that the storage shelf 20 does not rattle, for example, it is possible to easily add the storage shelf 20 with the sturdy shelf frame 40.

[0022] The experimental bench 1 according to this embodiment is not limited to the case where the storage shelf 20 is provided from the beginning. For example, by attaching the support pillar 41 in advance between the workbenches 10 arranged face-to-face, it is possible to easily add the storage shelf 20 later and systematize it.

[0023] Note that the storage shelf 20 is pre-unitized into a common structure with the front and back integrated, so that it can be used by the users of each experimental bench 1 from their respective workbench 1 sides. Of course, considering workability, it is also possible to configure the storage shelf 20 differently for each experimental bench 1.

[0024] In addition, the shelf frame 40 is not limited to the case where a plurality of them are arranged side by side in the left - right (illustrated arrow X) direction, and for example, it may be a single unit.

[0025] In the storage shelf 20, the storage shelf 70 is arranged, for example, so as to be divided into four parts (2 - stage × 2 - row) vertically and horizontally between the first erection part 43 and the second erection part 44 of the right - hand shelf frame 40. The storage shelf 70 is communicated so that it can be used concurrently on both experimental tables 1, and a fall - prevention guard 70a is provided at each opening serving as an access opening.

[0026] As the elevating storage cabinet 50, for example, three elevating shelves 51 are provided via a link mechanism below the first erection part 43 of the left - hand shelf frame 40. Each elevating shelf 51 is pulled forward so as to avoid the storage shelf 60 as appropriate and lowered near the work table surface SF by operating an elevating handle 52 by the user of the experimental table 1.

[0027] Thereby, the user can pull the elevating shelf 51 of the elevating storage cabinet 50 close to hand while sitting on a chair (in a posture). As a result, it becomes easy to take in and out the equipment stored in the elevating shelf 51, and the work efficiency is remarkably improved.

[0028] Each elevating shelf 51 is, for example, divided into two upper and lower stages, and fall - prevention guards 51a are respectively provided at the access openings.

[0029] The storage shelf 60 is provided, for example, with substantially the same width on the front surface part (front side) of the second erection part 44 of the left - hand shelf frame 40. On the upper surface of the storage shelf 60, a storage part 61 that is flat and can store various equipment is fixed, for example, to the front surface part of the connecting pillar 42 so as to be substantially at the same height as the upper surface of the second erection part 44.

[0030] In the storage unit 61, as shown in FIGS. 5 and 6 for example, a movable guard 62 for preventing falling is provided at the entrance / exit side (front end portion). The movable guard 62 can be easily pushed down from a predetermined guard position by hand or the like when the user takes in and out equipment, for example, by a click hinge (not shown). The pushed-down movable guard 62 automatically returns to the guard position.

[0031] Note that FIG. 5 is an enlarged view of the vicinity of part V in FIG. 1, showing a state where the lifting shelf 51 is not pulled out. FIG. 6 is an enlarged view of the vicinity of part VI in FIG. 4. As shown by the arrow in the figure, since the position of the movable guard 62 can be changed, it is possible to more easily take in and out equipment while suppressing the accidental fall of the equipment from the storage unit 61.

[0032] On the lower surface of the storage shelf 60, as shown in FIGS. 1 to 3 for example, it is possible to attach a holder 90 for temporarily holding (storing) equipment in use. In addition to attaching to the lower surface of the storage shelf 60, the holder 90 can also be attached to, for example, the second installation part 44 of the shelf frame 40 on the right side.

[0033] Between the connecting pillars 42 of the shelf frame 40 behind the work table surface SF of the workbench 10, as shown in FIGS. 7 and 8 for example, a storage box (guide member) 81 in which a power tap, a gas burner, etc. (not shown) are stored is provided. The storage box 81 is always covered by a lid part (lid body) 82 that can be opened and closed manually.

[0034] Between the storage box 81 and the like on the inner end side of the work table surface SF, as shown in FIG. 8, a liquid spill recovery groove (liquid recovery groove) 85 for recovering liquid (spilled liquid) spilled on the work table surface SF is disposed close to the lid part 82. The liquid spill recovery groove 85 is for preventing the spilled liquid from entering the storage box 81, and is, for example, a rectangular groove with a width of about 15 mm that is disposed along the left-right direction (X direction) on the inner side of the work table surface SF and is open upward.

[0035] The dripping liquid recovery groove 85 uniformly has, for example, a number of gaps 86 serving as recovery ports on the work table surface SF side, and a groove cover (a cover member such as a rubber packing) 87 that covers the upper surface opening portion of the dripping liquid recovery groove 85 is provided. The groove cover 87 has, for example, a cross-sectional shape that is curved in an arc shape upward.

[0036] Thereby, while suppressing the dripping liquid from proceeding to the storage box 81 side beyond the groove cover 87, the dripping liquid can be surely recovered in the dripping liquid recovery groove 85 through the gaps 86. Therefore, even if liquid is accidentally spilled on the work table surface SF during operations such as experiments and inspections, it is possible to avoid the dripping liquid from entering the storage box 81 and the power taps and the like arranged in the storage box 81 from leaking electricity.

[0037] Also, when the groove cover 87 is formed of a rubber packing, it is easy to change the shape (degree of curvature) and adjust the gaps 86, and an effect of shock absorption against falling objects can also be expected.

[0038] Also, by providing the groove cover 87, it is possible to prevent instruments, writing utensils, etc. from falling into the dripping liquid recovery groove 85.

[0039] In particular, when the groove cover 87 is configured to be detachable from the dripping liquid recovery groove 85, it is also suitable when cleaning the inside of the dripping liquid recovery groove 85. Therefore, even if the spilled liquid is a harmful chemical, it is possible to immediately recover and clean all of the spilled chemical, ensuring high safety.

[0040] Note that the dripping liquid recovery groove 85 can also be configured to be detachable together with the lid portion 82, for example. Thereby, when the lid portion 82 is removed, the dripping liquid recovery groove 85 can be taken out, so that the maintainability for repairs and the like can also be improved.

[0041] The sink 30 is for cleaning the equipment used in experiments, inspections, etc. In addition to the faucet 31 and the sink 33, it is equipped with, for example, a recovery device 35 for recovering used chemicals, etc. The sink 30 is also equipped with a splash guard 36.

[0042] On the back side of the sink 30, between each experimental table 1, there is disposed a unit device 37 equipped with, for example, a recovery tank 88 for storing the dripping liquid recovered by the dripping liquid recovery groove 85 and a drain pipe 89. The recovery tank 88 is preferably configured to be easily detachable from the unit device 37 for draining.

[0043] In addition, it is also possible to provide, for example, pipes for water supply and drainage for the sink 30 inside this unit device 37.

[0044] It is desirable that the working table surface SF of the experimental table 1, the upper surface of the sink 30, and the upper surface of the unit device 37 be at the same height in consideration of workability.

[0045] As described above, according to this embodiment, the liquid spilled on the working table surface SF during work can be surely recovered, and it is possible to easily avoid the intrusion of dripping liquid into the storage box 81 where a power tap, etc. is arranged.

[0046] That is, a dripping liquid recovery groove 85 with a groove cover 87 is provided between the working table surface SF and the storage box 81 where a power tap, etc. is arranged. Thereby, while suppressing the dripping liquid from advancing to the storage box 81 side beyond the groove cover 87, the liquid spilled on the working table surface SF can be accurately recovered. Therefore, even when a large amount of liquid is spilled, it is possible to prevent the dripping liquid from entering the storage box 81 and avoid the leakage of the power tap, etc. arranged inside.

[0047] In particular, by providing the gap 86, only the dripping liquid can be easily recovered, and it is possible to prevent the equipment in use from accidentally falling. Also, by making the groove cover 87 detachable, it becomes possible to easily perform cleaning inside the groove, etc.

[0048] Note that the drip liquid recovery groove 85 is not limited to being provided on the lid portion 82 side, and may be configured to be disposed at the inner end portion of the work table surface SF.

[0049] Also, the recovery tank 88 is not limited to being provided within the unit device 37, and can also be disposed below the storage box 81 along the drip liquid recovery groove 85.

[0050] In addition, the drip liquid recovery groove 85 of the experimental bench according to the present embodiment can recover not only drip liquid but also cleaning liquid, disinfectant liquid, etc., and further, it is also possible to recover powders, etc.

[0051] <Other Embodiments> As described above, an aspect of the present invention has been described by way of examples of embodiments. However, these are merely examples, and the scope of the invention described in the claims can be variously modified without departing from the gist of the invention.

[0052] That is, the experimental bench 1 can be appropriately applied according to the use, such as experimental facilities and research facilities of companies, universities, etc., and specialized inspection institutions.
