Mode for Carrying Out the Invention

[0012] Hereinafter, embodiments of 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 are different from the actual ones.

[0013] <One Embodiment> Fig. 1 is a perspective view showing the schematic configuration of a laboratory bench 1 according to an embodiment, Fig. 2 is a front view of the laboratory bench 1, and Fig. 3 is a side view showing the laboratory bench 1 from the side of the 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.

[0014] The laboratory bench 1 according to this embodiment is a laboratory bench equipped with a swing-type lift-type storage cabinet 50, and is structured such that an operator (user) can take in and out equipment with respect to the lift-type storage cabinet 50 almost in the working posture without using a step ladder or the like.

[0015] That is, as shown in Figs. 1 to 4 for example, this laboratory bench 1 includes a workbench 10 as a work table for an operator to perform operations such as experiments and inspections, and a storage shelf 20 disposed at the upper rear of the workbench 10 for storing various equipment used in the work. Examples of various equipment stored in the storage shelf 20 include experimental instruments, inspection devices, or chemicals such as reagents used in the work.

[0016] Here, as an example of the system, an experimental bench 1 consisting of a storage shelf 20 and a workbench 10 arranged on the front side of the storage shelf 20 is structured in a face-to-face arrangement such that the workbenches 10 are line-symmetrical on both sides of the storage shelf 20, and a shared sink 30 is provided.

[0017] Note that since each experimental 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 experimental benches 1 will be described.

[0018] On the experimental bench 1, the workbench 10 includes, for example, a plurality (here, four) of drawers 12 and movable side tables (cabinet wagons) 14, 15 arranged below the drawers 12, and enables work in a seated state on a chair (not shown).

[0019] The storage shelf 20 has, for example, two sturdy steel shelf frames (bridge structures) 40 arranged side by side in the left - right (arrow X in the figure) direction, a liftable storage cabinet 50 arranged on one side of the shelf frame 40, a storage shelf 60, and a storage shelf 70 arranged on the other side of the shelf frame 40.

[0020] The shelf frame 40 is a pair of columns and is composed of a connecting pillar (extension pillar) 42 connected to the support pillar 41 and a first erected part 43 and a second erected part 44 erected between the connecting pillars 42.

[0021] 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, behind the workbench 10 (in the direction of arrow Y in the figure), and is firmly attached and fixed almost over the entire length in the vertical (arrow Z in the figure) direction of the workbench 10 near both the left and right ends and the central part near the back end of the work table surface SF.

[0022] Therefore, by firmly connecting the connecting pillar 42 to the support pillar 41 so that, for example, the storage shelf 20 does not rattle, it is possible to easily add the storage shelf 20 with the robust shelf frame 40.

[0023] The experimental table 1 according to the present 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 work desks 10 arranged face-to-face, it is possible to easily add the storage shelf 20 later and systematize it.

[0024] Note that the storage shelf 20 is pre-unified into a common structure with the front and back integrated, so that it can be used by the users of each experimental table 1 from their respective work desk 10 sides. Of course, considering workability, it is also possible to configure the storage shelf 20 differently for each experimental table 1.

[0025] Also, the shelf frame 40 is not limited to the case where a plurality of them are arranged side by side in the left-right (arrow X in the figure) direction. For example, it may be a single unit.

[0026] In the storage shelf 20, the storage shelf 70 is arranged, for example, to be divided into four parts (2 tiers × 2 rows) vertically and horizontally between the first installation part 43 and the second installation part 44 of the right shelf frame 40. The storage shelf 70 is communicated so that it can be shared by both experimental tables 1, and a guard 70a for preventing falling is provided at each opening serving as an access opening.

[0027] As the elevating storage cabinet 50, for example, three elevating shelves 51 are provided below the first installation part 43 of the left shelf frame 40 via a link mechanism. Each elevating shelf 51 is pulled forward so as to avoid the storage shelf 60 as appropriate and lowered to near the work table surface SF by operating the elevating handle 52 by the user of the experimental table 1.

[0028] As a result, the user can pull the lift shelf 51 of the lift-type storage cabinet 50 close to the vicinity of the hands while remaining seated on the chair (in a posture). As a result, it becomes possible to easily take in and out the equipment stored in the lift shelf 51, and the work efficiency is significantly improved.

[0029] Each lift shelf 51 is, for example, divided into two upper and lower stages, and guard members 51a for preventing falling are respectively provided at the access openings.

[0030] The storage shelf 60 is provided, for example, on the front surface (front side) of the second installation part 44 of the shelf frame 40 on the left side with substantially the same width. On the upper surface of the storage shelf 60, a storage part 61 that is flat and can store various equipment is fixed to the front surface of the connecting pillar 42, for example, so as to be substantially at the same height as the upper surface of the second installation part 44.

[0031] In the storage part 61, for example, as shown in FIGS. 5 and 6, a movable guard (guard member) 62 for preventing falling is provided at the access opening side (front end part). The movable guard 62 can be easily pushed down from a predetermined guard position by hand or the like, for example, when the user takes in and out the equipment. The pushed-down movable guard 62 is configured to automatically return to the guard position.

[0032] Note that FIG. 5 is an enlarged view of the vicinity of part V in FIG. 1, and here shows a state where the lift shelf 51 is not pulled out. FIG. 6 is an enlarged view of the vicinity of part VI in FIG. 4.

[0033] 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 the equipment with respect to the storage part 61 while suppressing the accidental fall of the equipment from the storage part 61.

[0034] 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 or the like. 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. Details of the holder 90 will be described later.

[0035] Between the connecting pillars 42 of the shelf frame 40 behind the work table surface SF of the workbench 10, as shown in FIG. 7 for example, a storage box 81 storing a power tap or a gas burner (not shown) is provided. The storage box 81 is constantly covered by a lid part (lid body) 82 that can be opened and closed manually.

[0036] Between the inner end side of the work table surface SF and, for example, the storage box 81, as shown in FIG. 7, a dripping liquid recovery groove (liquid recovery part) 85 for recovering liquid (dripping liquid) spilled on the work table surface SF is disposed close to the lid part 82. The dripping liquid recovery groove 85 is for preventing the dripping 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.

[0037] The dripping liquid recovery groove 85 is provided with a groove cover (cover member such as a rubber packing) 87 that uniformly has a slight gap 86 serving as a recovery port on the work table surface SF side and covers the upper surface opening part of the dripping liquid recovery groove 85. The groove cover 87 has, for example, a cross - sectional shape that curves in an arc shape upward.

[0038] 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 gap 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 causing leakage of a power tap or the like arranged in the storage box 81.

[0039] In addition, by providing the groove cover 87, it is possible to prevent equipment, writing utensils, etc. from falling into the dripping liquid recovery groove 85 beforehand.

[0040] 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.

[0041] Note that the dripping liquid recovery groove 85 can also be configured to be detachable together with the lid portion 82, for example.

[0042] The sink 30 is for cleaning the equipment used in experiments, inspections, etc. In addition to the faucet 31 and the sink 33, for example, it is equipped with a recovery device 35 for recovering used chemicals, etc. The sink 30 is also equipped with a splash guard 36.

[0043] On the back side of the sink 30, between each experimental table 1, for example, a unit device 37 equipped with a recovery tank 88 for storing the dripping liquid recovered by the dripping liquid recovery groove 85 and a drain pipe 89 is arranged. The recovery tank 88 is preferably configured to be easily detachable from the unit device 37 for draining.

[0044] Note that it is also possible to provide, for example, piping for water supply and drainage for the sink 30 inside this unit device 37.

[0045] 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.

[0046] Here, the configuration of the storage shelf 60 and the holder 90 provided on the storage shelf 60 will be further described.

[0047] In the present embodiment, as shown in FIG. 8, for example, a storage basket 91 and a storage holder (pipette holder) 92 as the holder 90 can be arranged on the lower surface of the storage shelf 60.

[0048] That is, the storage shelf 60 provided in the experimental bench 1 according to the present embodiment is formed of a metal such as aluminum, and has a cross-sectional shape with a predetermined inclined surface such that the base end side is thick and gradually becomes thinner toward the tip (front end) side, as shown in FIGS. 9(a) and 9(b), for example. Further, the storage shelf 60 has a length substantially the same as the width in the left-right direction (X direction) of the second installation portion 44 of the left shelf frame 40.

[0049] The base end side of the storage shelf 60 abuts against the front surface portion of the second installation portion 44 of the left shelf frame 40 via the connection member 66, and in that state, it is fixed to the front surface portion of the connecting pillar 42 by the screwed end cap 161 (see FIG. 6, for example).

[0050] The height of the storage portion 61 on the upper surface of the storage shelf 60 is adjusted so as to be substantially the same as the height of the upper surfaces of the connection member 66 and the second installation portion 44. Thereby, a storage space as the storage portion 61 is secured wider by the amount of the upper surfaces of the connection member 66 and the second installation portion 44.

[0051] Note that on the upper surface of the storage shelf 60, support grooves 64 for pivotally supporting a pair of arm portions 162 of a plurality of movable guards (guard members) 62 that individually form a fall prevention device are formed, and on the lower surface (inclined surface) of the storage shelf 60, mounting grooves 63 for attaching the holder 90 are formed, respectively. The mounting groove 63 has a substantially trapezoidal cross-sectional shape with a downward opening portion formed along the left-right direction (X direction) of the experimental bench 1. The support groove 64 has a substantially circular cross-sectional shape with an upward opening portion formed along the left-right direction of the experimental bench 1.

[0052] One end (base end portion) side of a pair of arm portions 162 for vertically moving the movable guard 62 for fall prevention is pivotally supported in the support groove 64 via a free-stop type click hinge (hinge member) not shown in the figure.

[0053] Note that between the pair of arm portions 162, a hinge receiver (not shown) for closing the opening portion of the support groove 64 while maintaining the distance between the pair of arm portions 162 is inserted.

[0054] In addition, in the present embodiment, a case where three movable guards 62 are arranged in the left - right direction on the storage shelf 60 is illustrated. However, the present invention is not limited to this. The number, length, etc. of the movable guards 62 with respect to the storage shelf 60 can be appropriately changed according to the equipment to be stored.

[0055] The storage basket 91 as the holder 90 is attached below the storage shelf 60 via first and second holding members 93 and 94 locked to the attachment groove 63, as shown in FIGS. 8 and 9(a) and (b), for example. The storage basket 91 may be configured to be slidable along the attachment groove 63 together with the first and second holding members 93 and 94, for example.

[0056] The storage basket 91 has an open upper surface and is attached to the inner surface (first surface) side of the first holding member 93, for example.

[0057] Then, with the first holding member 93 on the back side of the attachment groove 63 and the second holding member 94 on the front side of the attachment groove 63, the storage basket 91 is attached to the attachment groove 63 at an angle different from that of the storage holder 92 by being screwed with a screw 95 from the second holding member 94 side.

[0058] That is, the attachment angle of the first holding member 93 to the attachment groove 63 of the basket attachment portion 93a is set to be substantially in the vertical direction (Z direction), for example, greater than 90 degrees. In this case, by attaching the storage basket 91 to the inner surface of the first holding member 93, the storage basket 91 is fixed to be substantially horizontal.

[0059] Note that in a state where the screw 95 is removed, the storage basket 91 can be attached to and detached from the attachment groove 63 by shifting the positions of the first holding member 93 and the second holding member 94 in the opposite direction within the attachment groove 63.

[0060] Similarly, the storage holder 92 as the holder 90 is attached below the storage shelf 60 via first and second holding members 93 and 94 locked to the attachment groove 63, as shown in FIGS. 8 and 10, for example. The storage holder 92 may be configured to be slidable along the attachment groove 63 together with the first and second holding members 93 and 94, for example.

[0061] The storage holder 92 has a plurality of circular through-holes formed in an upper plate and a lower plate interconnected by side plates, and is attached to the outer surface (second surface) side of the first holding member 93, for example.

[0062] Then, with the second holding member 94 on the inner side of the attachment groove 63 and the first holding member 93 on the front side of the attachment groove 63, the storage holder 92 is attached to the attachment groove 63 at an angle different from that of the storage basket 91 by being screwed with screws 95 from the first holding member 93 side.

[0063] That is, by attaching the storage holder 92 to the outer surface of the first holding member 93, the storage holder 92 is fixed substantially horizontally.

[0064] In addition, when the screws 95 are removed, the storage holder 92 is attached to and detached from the attachment groove 63 by shifting the positions of the first holding member 93 and the second holding member 94 in the reverse direction within the attachment groove 63.

[0065] By providing the holder 90 such as the storage basket 91 and the storage holder 92 on the lower surface of the storage shelf 60, it becomes possible to temporarily hold instruments such as a pipette and a reagent (chemical) in use.

[0066] That is, without hooking on a valve or the like operated when using a gas or a fluid, or without preparing a container or the like, the instrument in use can be temporarily retracted from the work table surface SF. As a result, it becomes possible to efficiently manage the instrument in use without interfering with the operation of a valve or the like or having trouble with the placement.

[0067] Moreover, in the storage basket 91 and the storage holder 92, it becomes possible to manage while distinguishing the equipment to be held at different angles.

[0068] Also, when the storage basket 91 and the storage holder 92 are configured to be slidable, the user can easily move the equipment to be held to a position where it is easy to work.

[0069] Therefore, it is possible to make the experimental bench 1 extremely user-friendly, such as significantly improving workability.

[0070] In particular, since the holder 90 is detachable, it becomes possible to prepare the holder 90 by retrofitting when necessary, and it is possible to share the holder 90 with other experimental benches 1, etc., resulting in cost reduction.

[0071] As described above, according to the present embodiment, it is possible to temporarily and efficiently hold the equipment in use, making it user-friendly and significantly improving workability.

[0072] That is, even when temporarily holding equipment in use, etc., it is possible to easily hold it by the storage basket 91 or the storage holder 92 below the storage shelf 60, etc., without using valves, containers, etc. Therefore, the work space is not temporarily occupied by the equipment in use, and it is possible to effectively use the limited work space, making it a very user-friendly experimental bench for the user.

[0073] <Other Embodiments> As described above, one 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.

[0074] For example, as the experimental bench 1, it can be appropriately applied according to the application, such as experimental facilities and research facilities of companies, universities, etc., and specialized inspection institutions.
