Definitions
- the invention relates to a laboratory workbench with a housing, with a working opening, the one in the housing arranged working space limited on one side, with a blower to generate an air flow in the work area and with a movable on the Housing arranged protective screen.
- Laboratory workbenches are, for example, from GB 2 112 927 A or from US-A-4 179 984 known. Also in the company brochure "Biological safety cabinets Heraeus Laminair HB and HBB "from Heraeus Instruments GmbH discloses such a laboratory workbench. Laboratory workbenches generally serve to protect the product processed or processed therein, the operator and / or the environment. Safety is ensured by suitable air routing guaranteed. For laboratory workbenches where product protection is paramount Prevent contamination from the environment from entering the work area. For this purpose, an air flow generated by the blower is from the work space directed out through the work opening.
- the object of the present invention is therefore to provide a laboratory workbench with a suitable possibility of movement to create for the protective screen where the risk of accidents to a minimum is reduced, at the same time protecting the operator from influences from the work area becomes.
- the protective pane in the upper area the working opening is held on the housing in such a way that it is between a hanging, the working opening at least partially covering position and in the housing projecting position, in particular movable into an at least approximately horizontal position is.
- Such laboratory workbenches are particularly advantageous to operate in that the the fan generated air flow directed essentially horizontally through the work space is so that as uniform as possible over the entire cross section of the working opening There is pressure from the work area to the environment.
- Such workbenches with in the environment Directed airflow are also called product protection cabinets because they are primary are aimed at contamination of the work area or product by germs to prevent the environment.
- the protective screen not only acts as protection against drafts or as a splash guard, but it also acts as a touch protection for the spotlights and protects This prevents mechanical destruction and the operator from burns or other injuries.
- the protective screen is usually made of glass. This is for UV radiation largely impermeable, so that the protective screen at the same time against the ultraviolet Protects radiation.
- This protection against ultraviolet radiation exists with folded down protective screen against both direct and reflected radiation from the work area to an operator, but it also protects the arms, for example the operator with the protective screen folded up, so that accidental UV radiation, for example, the operator's arms when the protective screen is raised is possible because it is advantageously in its horizontal position below the lighting device is arranged
- the protective pane is arranged horizontally Bolt is rotatably mounted in the housing. Furthermore, it is appropriate that Locking devices on the housing and / or on the protective pane for locking in the hanging and / or the horizontal position of the protective pane are provided for a simple To ensure movement and fixation of the protective screen.
- an extension disk may be arranged movably on the protective disk is such that the extension disk in front of one not covered by the protective disk Part of the work opening is movable.
- the Extension disc for example by means of a hinge joint, on the lower edge of the Protective screen is arranged foldable.
- the extension disk in a different way, for example displaceable parallel to the protective pane on the latter to arrange.
- the laboratory workbench 1 also called the product protection workbench, is arranged on a table frame 2. It has a working space 3 which is perforated at its rear end Wall 4 is limited and a functional unit 5 is arranged at the upper end.
- the Functional unit 5 contains essential electrical and electronic functional elements, filters and other components. Through the perforation of the rear wall 4 flows horizontally towards the front Air that is moved by a fan arranged in the functional unit 5.
- the work space 3 is limited on its side walls by side windows 6 and on its front Side through the work opening.
- FIG. 2 shows the arrangement of the protective pane 7 of the laboratory workbench 1
- the figures 2 a and 2 c show a folded, hanging protective screen 7 and in FIG. 2 b an in its horizontal position in the interior folded protective screen 7 is shown.
- the lighting device 8 which is in the lower part of the Functional unit 5 and above the work area 3 is arranged.
- the air flow will shown by the arrows in Figures 2 b and 2 c.
- the lighting device 8 can completely or partially formed from UV rays.
- FIG. 3 shows a laboratory workbench 1, with an extension disk on the protective disk 7 9 is arranged.
- the expansion disk 9 is by means of a hinge joint on the lower edge the protective disc 7 is arranged and can be against the inside (into the work area) the protective screen 7 can be pivoted. In this situation, it is conveniently located on the Protective disc 7 locked, for example by means of not shown in the drawing, but generally well-known locking devices (hooks, bolts or the like).
- the expansion disk 9 has a through opening 10 at its lower end, which extends over the largest Part of the width of the extension disk 10 extends.
- FIG. 3 b arrows show the ultraviolet radiation emitted by the lighting device 8 goes out, shown. It is clearly recognizable that one in front of the work opening of the laboratory workbench 1 standing operator through the protective pane 7 including the extension pane 9 is largely protected from the influence of ultraviolet radiation.
