Description

    The present invention relates to an experimental bench used for chemical experiments and the like.

    Conventionally, there are various types of test benches used for chemical experiments and the like.

    As one of the representative ones, there is an experimental bench as shown in FIGS. 8 is a plan view, FIG. 9A is a front view, and FIG. 9B is a side view. As shown in FIG. 8, two testers A and B, for example, work on the surface indicated by the reference numerals 12A and 12B in two directions on the top board 12, for example. is there. In this way, this type of experimental table is a work on only two surfaces, and the amount of work is limited.

    In general, an experimental bench is used by using various devices, and space for storing and arranging these devices is required. Moreover, chemicals are often used, and a space for storing these chemicals is required.

    For these reasons, the lower part of the top 12 on which the experiment is carried out is generally a storage as shown in FIG. 9, and the equipment and chemicals used in the experiment are stored in the storage 17 below the top 12. They are stored and used as needed. Some drawers 18 are arranged on the left and right sides of the storage case 17. Further, in the middle part of the experimental table indicated by the reference numeral 16 in the center, a wiring from a water pipe, a gas pipe or a power source for supplying tap water or a gas burner used for the experiment is generally provided below the top plate 12. It has been. A water tap, a gas tap, an outlet, and the like connected to them are installed in the central portion 16 of the experimental table. And supply of tap water, connection of a gas burner, supply of electric power to devices using a cord from an outlet through a tube from these taps, gas stoppers, and outlets.

    In some experimental benches, a reagent shelf is installed in the central portion 16 to store chemicals to be used. In this case, the above-mentioned water tap, gas tap, and outlet are often installed on the wall surface at the lower end of the reagent shelf near the central lower pipe.

    As described above, the conventional experimental bench shown in the figure is limited to the experiment with two persons (two places) facing each other as described above.

    In addition, the storage is limited to the lower part where the tabletop experiment is conducted, which is not sufficient.

    In addition, depending on the content of the experiment, there are some that need to be performed in parallel with other experiments related to this in addition to the experiments performed on the experimental bench.

    FIG. 8 shows an outline of a laboratory using a laboratory bench. In this example, the laboratory bench 10 is arranged in the center of the laboratory, and a spare laboratory bench ( Side experiment table) 13, 14, and 15 are provided.

    In addition, although not shown, in the storage below the top plate of the laboratory table, equipment that cannot be stored, especially large equipment that cannot be stored, should be placed in an appropriate position in the laboratory so as not to interfere with the experiment. There is also.

    As described above, depending on the contents of the experiment, it is necessary to perform an experiment by moving to the side experiment table on the wall surface together with the work on the center experiment table. In addition, depending on the content of the experiment, the experiment had to be performed while repeating the movement between the central experimental table 10 and the side experimental tables 13, 14, and 15.

    Further, when one experimenter A performs an experiment by moving to the far side of the side experiment table 13, or the experiment by the opposite experimenter B moving to the side experiment table 15. Often done.

    In addition, as described above, below the top plate of the experimental table is generally a storage for storing instruments, devices, and the like. It is desirable that the storage be provided with a storage arrangement that is preferable for experiments according to the type of equipment and the like so as to facilitate work by providing a partition shelf inside.

    However, the conventional test bench is an experiment on two opposing surfaces, and experiments are conducted in opposition to each other. For this reason, the equipment and the like are taken into and out of the storage from the side to be tested, that is, from the front side and the back side. Therefore, the arrangement method of the equipment in the storage is limited.

    The present invention provides an experimental bench capable of performing experiments in four directions on one top plate.

    In addition, the present invention provides an experimental bench that allows experiments in four directions and is configured to change the arrangement, orientation, and the like of the storage provided at the bottom of the top plate. is there.

    The experimental bench according to the present invention is characterized in that the experiment can be performed on the left and right in addition to the surface for performing the experiment in two opposite directions.

    As a result, work on the experimental table can be performed at four locations, and many different experiments can be performed by many experimenters at once.

    In particular, plumbing was carried out, and it was possible to work on four sides without changing the central part (utility part) where the water tap, gas stopper, and outlet were installed, or the lower part thereof.

    Furthermore, when the same experimenter performs a plurality of experiments, an experiment can be performed on any one of the left and right sides of the side surface used by a single experimenter, so the movement distance between the two side surfaces is small. For example, two experiments can be performed with little movement.

    In addition, most experiments can be performed without installing a side experimental bench, and the laboratory can be used effectively. For example, it is possible to install equipment at the place where the conventional side test bench is installed, or install chemical storage, increasing storage space and organizing storage suitable for experiments and chemicals. , You can conduct efficient experiments.

    In addition, the experiment table of the present invention is capable of experiments on four surfaces as described above, thereby enabling the storage of the lower part of the top plate to be changed in the direction of the storage port of the article, The degree of freedom of usage increases.

    Therefore, the experimental bench of the present invention is also characterized by unitizing the storage to be placed under the top plate, and by arranging and using units of different sizes, shapes, etc. It becomes easy to make a preferable arrangement according to the contents of the experiment.

    In particular, the utility part in the center is also unitized, and the unitized utility part, the shape of each unitized storage and the combination of them, the configuration of each unitized part can be freely selected and unitized The arrangement and the like can be easily changed by changing the combination of the parts.

    The experimental bench of the present invention increases the number of experiments that can be performed simultaneously and independently due to an increase in work surface, and moreover, it is possible to improve efficiency when simultaneously performing related experiments. Further, the layout and other degrees of freedom including the direction of the entrance / exit of the lower storage due to the increase of the work surface increase. In particular, the unitization of the utility unit and the unitization of each storage can easily change the arrangement of each unitized unit and the overall configuration.

    Embodiments of the present invention will be described based on examples shown in the drawings.

    FIG. 1 is a diagram showing an embodiment of an experimental bench according to the present invention, and is a diagram including an outline of the layout of the entire laboratory.

    In the figure, reference numeral 1 denotes an experimental bench (central experimental bench) according to the present invention, in which one top plate 2 is composed of four experimental spaces 2a, 2b, 2c, and 2d, and two directions 2A, 2B, 2C, and 2D. It has a shape and configuration that can be used for experiments. Therefore, in addition to the two testers A and B facing each other, the use by the testers C and D who conduct the experiment at the left and right positions (experimental spaces 2c and 2d) becomes possible.

    In addition, an independent experiment by four persons A, B, C, and D is possible (an independent experiment twice as much as the conventional one). For example, when two independent experiments of A and B are performed, they are parallel in parallel. When performing related experiments, the left and right experimental spaces 2c and 2d can be used. Thus, as in the conventional example shown in FIG. 8, for example, a spare side experimental bench installed on the wall surface becomes unnecessary. In addition, the distance traveled by the experimenter is significantly reduced. For example, instead of moving to the side experiment table on the wall surface, the worker A may perform an experiment on the side surface using either the left or right experimental space 2c, 2d, and move for switching the experiment. Is extremely easy. In addition, as described above, only a slight movement is required in both the right and left cases. When the worker A in the conventional example shown in FIG. 8 uses the side experimental bench 13, the worker B uses the side experimental bench 15. The inconvenience like a case is completely eliminated.

    In addition, even when the worker A uses the experimental space 2c and the experimental space 2d, and the worker B uses the left and right experimental spaces 2c and 2d, the work surface is on the same top plate. In addition, since the chemicals and the sample during the experiment are moved on the top plate surface, it is possible to greatly shorten the working time. In particular, in the case of the conventional example, the medicine or sample may be spilled during the movement of the medicine or sample, or the medicine, the sample or the like may be spilled or damaged. Few.

    In addition, it becomes possible to place the equipment in the place where the side experimental bench has been installed in the laboratory, and to arrange the equipment in an organized manner.

    Further, by arranging the above place as a storage, it is possible to store chemicals in an organized manner.

    FIG. 2 is an embodiment having a feature in the arrangement of the storage at the bottom of the top plate in Embodiment 2 of the present invention.

    In the second embodiment, two rectangular units 5A and two square units 5B are arranged as shown in the figure as storage units. The central unit 6 is a utility unit that houses and arranges a water pipe, a water tap, a gas pipe, a gas plug, a power outlet, a cord, and the like.

    In this embodiment, a top plate is installed on a unit as shown in the figure, and like the first embodiment, this is an experimental table capable of experiments from four directions on the top plate.

    And this experiment stand is the arrangement | positioning in which the taking in / out of the apparatus and chemical | medical agent in a storage are performed only in the upward direction and downward direction of drawing.

    Next, FIG. 3 shows another example of arrangement using the same unit. In this example, the square unit 5B is rotated by 90 °, whereby the unit 5A is used from the vertical direction of the drawing, while the unit 5B is used from the horizontal direction of the drawing.

    Thus, the experimental bench of the present invention can be used differently, for example, by changing the orientation of the unit arrangement position.

    Another embodiment 3 of the present invention has a configuration as shown in FIG.

    As shown in FIG. 4, the experimental bench of the third embodiment has a configuration in which the central utility unit 7 has a substantially square shape and four units 8 are arranged in the vicinity thereof as shown in the figure.

    In the third embodiment, an experiment on four surfaces is performed, and the feature is that the unit 8 including each experimental top plate and storage is the same space. Therefore, four independent experiments under the same conditions can be performed.

    It is also an advantageous configuration when two experiments involving a single worker are performed.

    The third embodiment is also characterized in that the utility unit has a substantially square shape as shown in FIG. And as shown in FIG. 5, it is also characterized by making it the tower shape which raised the utility unit 7 upwards.

    As described above, the utility unit is formed in a tower shape, and the outlet 21, the water tap 22, and the drainage pot 23 are further provided in the unit.

    In addition, as shown in FIG. 5, the unit 8 as an experimental table includes a unit 8A having a normal height (a height at which the experiment is performed standing up) and a unit 8B capable of sitting at a low height. A combination configuration is also possible.

    Thus, when performing the same work for a relatively long time, the unit 8B is used, and the unit 8A is used for an experiment in which a standing work is preferable. In addition, the unit 8A having a normal height and the unit 8B having a low height are disposed adjacent to each other, so that it is possible to achieve a preferable configuration for an experiment in which both workers need to continuously perform both operations.

    Furthermore, it is possible to use a combination of a plurality of experimental benches. The example is a combination arrangement as shown in FIG. In the combination shown in FIG. 6, for example, workers A and B can work on the top plate indicated by hatching.

    As described above, by combining the experimental tables in which the units 7 and 8 shown in FIG. 4 are combined, it becomes possible to perform more independent operations, and when performing a plurality of operations by one operator, More efficient work can be done.

    In addition, the conventional experimental bench is made on the assumption that the work is performed on the front surface or the back surface on the opposite side. For this purpose, the leg 25 at the lower part of the experimental table, called the pedestal, has the shape shown in FIG. In other words, on the side where the work is performed, the leg portion 25 is located inside the surface 26, and a fixed space is formed between the leg portion and the toe of the worker during the work. It is designed not to hit the table. However, as shown in FIG. 7C, the legs other than the work surface have leg portions formed along the end surfaces.

    When such a conventional test bench is used as it is as the test bench of the present invention so that the experiment can be performed on the side surface, it is preferable to conduct an experiment in the direction shown in FIG. Absent.

    Considering this point, in the present invention, as shown in FIGS. 7A and 7B, the leg portion 25 is slightly retracted inward on any surface to provide a space. . Thereby, work in any surface can be performed satisfactorily.

    In addition to the above-described example, by preparing units of various shapes, it is possible to easily change experimental benches of various different usage patterns. In other words, it is an experimental bench that is configured to allow experiments on four surfaces, which is the basic configuration of the experimental bench, and can constitute an experimental bench with a different unit arrangement. Therefore, it is possible to arrange an optimum unit according to the experiment contents and to easily change the unit.

    The present invention is used when performing experiments such as chemical experiments on a laboratory table arranged in a laboratory, and by increasing the number of work surfaces to be performed independently, many types of experiments can be performed at once. And, in related experiments, experiments that need to be performed simultaneously or sequentially can be performed efficiently. In addition, the degree of freedom of the placement of the storage cabinet at the bottom of the top plate for experiments is increased, and in particular, the placement and configuration of the bottom plate can be easily changed by unitizing the utility part in the center and unitizing each storage. .
