Definitions
- the invention relates to a floor pan for arrangement in the lower section of a work space a safety cabinet.
- Floor trays for safety cabinets are required to hold amounts of material such as liquids from the work area. These quantities of material come from the worktop in the work area via air intake slots or slots in the worktop area into the floor pan.
- the object of the invention is accordingly with a floor pan for safety cabinets to provide a defined collection area, which can be produced inexpensively in small quantities is. There should be as few additional and complex work steps as possible.
- the floor pan according to the invention has a floor area surrounded by side walls in the deepest area of which there is a collection area, the floor area at least partially sloping towards the collection area and being the height the side walls tapering towards the collection area in the direction of the collection area takes.
- the floor area of a floor pan according to the invention can therefore also run horizontally Have floor area sections. At least one floor area section is in the direction of inclined the collection area.
- the floor area can also be designed in steps.
- the entire area of the floor area sloping towards the collecting area preferably continuously falling, inclined.
- the height of the side walls therefore increases accordingly continuously towards the collection area.
- the gathering area in a corner of the floor area there is advantageously the gathering area in a corner of the floor area. From this collection area, the collected liquid can be removed very easily.
- the liquid can be removed by hand from the Collection area can be eliminated, or the liquid can drain the collection area through a drain leave with an opening in the floor area.
- the drain opening can take various forms to have. It can be elongated, circular or any other shape imaginable.
- a closable drain line can also be arranged at the outlet.
- the bottom area can point in the direction of one of its side edges or part of its side edges be inclined. It is also preferred here the slope is continuous.
- the collection area is in the area an edge of the floor area of the floor pan.
- the collecting area can also be located essentially in the middle of a side edge of the bottom area are located.
- the side wall adjacent to the collecting area is then divided into two side wall sections that run from the corners of the side wall towards the collection area.
- the height of the side wall sections in each case Towards the collection area.
- the inclination is preferably continuous again, so that the height of the side wall sections also increases continuously.
- the maximum height of the side wall is thus in the middle of it, where the side wall sections meet, while the minimum height of the side wall is formed at the side end.
- the height of the side walls tapering towards the collecting area increases to. So not all side walls of the floor pan have a changing height exhibit. It is therefore possible for at least one side wall or a side wall section has a substantially constant height over its length. It is then expedient to do so this side wall adjoining floor area section in a horizontal plane.
- the floor area is expediently only as much as is currently required inclined to the horizontal direction to ensure sufficient fluid drainage.
- the side walls can form an angle of 90 to 150 ° to the floor area, whereby an angle between 120 to 140 ° is preferred.
- the mounting of the floor pan in a safety workbench can basically be done in the state of the Technology done in the usual way.
- the ones remote from the floor area run accordingly Top edges of the side walls are expedient essentially in one plane, in particular in one essentially horizontal level.
- the floor pan seals the work area downwards.
- the conventional sealing materials are expediently used in the safety workbench.
- the front edges are close together bordering side walls or side wall sections connected together, expedient welded.
- the invention also includes a method for manufacturing the floor pan.
- the floor pan by bending the side walls from a sheet metal in such a way that the bending edges, which side edges of the floor area correspond to the floor pan, at an angle to the upper edges of the side walls run, so that when folding the surrounding area Side walls or side wall sections, each increasing in the direction of the collection area Height arise.
- the advantage of the manufacturing process is that only simple and inexpensive tools and Machines are required.
- the unwound floor pan according to the invention is made from sheet metal cut out.
- the cutting out can be done, for example, either by punching or using today's very inexpensive and flexible laser cutting. Especially that Laser cutting is suitable for small quantities because there are no additional tool costs in contrast to punching. Folding can be done with a conventional folding bench or press can be executed.
- the floor pan can be essentially made from one rectangular sheet can be cut out.
- gusset To simplify the manufacturing process of a floor pan according to the invention, before folding the side walls in areas of adjacent side walls or side wall sections cut-outs from the sheet, hereinafter called gusset.
- the gussets are basically in the corners of the processing of the floor pan. is the gathering area in the area between two side wall sections, gussets can also be cut in the middle of side walls.
- the collection area of the finished floor pan is therefore located in the central area of the corresponding side edge of the floor area.
- the side walls are preferably at an angle of 90 to 150 °, in particular 120 to 140 °, folded to the floor area.
- Reasons for this are, among other things, that the material quantities easier to catch and easier to lead to the collection area.
- the upper area of the floor pan is preferably designed like conventional floor tubs, to be able to fit them into safety cabinets according to the state of the art. Therefore the sheet in the area of the upper side walls of the floor pan, for example Appropriately along the upper edges of the floor pan as seen from the floor area to the outside folded.
- Fig. 1 shows schematically a safety workbench with a built-in invention Floor pan in side view.
- Fig. 2 shows schematically the developed floor pan of FIG. 1 in the Top view of how it is cut out of a sheet.
- FIG. 3 shows schematically the floor pan according to the invention from FIG. 1 in an isometric view View.
- FIG. 4 schematically shows the floor pan according to the invention from FIG. 1 in a front view.
- Fig. 5 shows schematically the floor pan according to the invention of Fig. 1 in a side view.
- Fig. 6 shows schematically the floor pan according to the invention of Fig. 1 in plan view.
- the safety workbench 1 shown in FIG. 1 essentially corresponds to a conventional one Safety workbench 1, as described for example in DE 44 41 784 C2.
- a frame 2 encloses a work area 3, in which samples can be processed.
- On the The front of the safety workbench 1 (in the figure on the left) is the work area 3 above a working opening is accessible, which can be closed with a windscreen.
- samples in the work area 3 and cleaning the worktop 4 can be minor Amounts of material through air intake slots 5 in the worktop 4 or slots between Worktop sections fall or flow into the underlying floor pan 6.
- the air intake slots 5 are required to circulate air inside the workbench.
- the floor pan 6 has dimensions such that it can be fitted into the frame 2.
- the floor pan 6 seals the work area 3 from below, so that no materials can escape from the safety cabinet 1.
- the collection area 9 of the floor pan 6 on the long side of the working opening, thus by hand if necessary, remaining stocks of the material quantities are pushed towards the collecting area 9 can.
- the upper edges 11 of the side walls 8 lie in a horizontal plane, so that the Worktop 4 can be used flat on the floor pan 6.
- the barrier 16 of the floor pan 6 is flush with the worktop 4, as shown in Fig.1 and in the state the technology is common.
- the starting point for the production of the floor pan 6 is a corrosion-resistant sheet, whereby a brushed stainless steel sheet is preferable.
- This sheet material has the advantage that the liquids and amounts of material collected in the floor pan 6 drain off well leaves.
- the sheet also has a film coating for protection during processing. The Foil is only completely removed after completion of the floor pan 6.
- the sheet is a flat development of a floor pan 6 according to the invention, as in Fig. 2 is cut out.
- the settlement from the sheet metal cut out with a laser is inexpensive for small quantities and very flexible with regard to the shapes to be cut out.
- gusset 12 laser cutting is ideally suited to the required recesses with each different sizes from the corners of the flat development of the floor pan 6 to to cut.
- These recesses hereinafter called gusset 12, are made with it when folding the side walls 8, sheet metal material does not overlap on the end faces of the side walls 8 and to then weld the end faces of the side walls 8 flush.
- the Lengths of the end faces of the side walls 8 thus essentially correspond to the lengths of the Sides of the gusset 12.
- the length of the end faces of the side walls 8 is determined on the one hand about the height of the side walls 8 and the other about the angle to be included between the floor area 7 and the side walls 8.
- the height of the run-up to the drain Side walls 8 increases in the direction of the collecting area 9, so that the collecting area 9 is at the lowest point of the floor area 7. It follows here that the end faces the side walls 8 are the longest in close proximity to the collection area 9 and the end faces of the side walls 8 that are farthest from the collection area 9 are the shortest. The smallest gussets 12 are thus furthest away from the collecting area 9 and are the largest closest to collection area 9. From the requirement of continuously increasing height of the side walls 8 in the direction of the collecting area 9 results in the example shown that the Bending edges 10, which correspond to the side edges of the base region 7 of the base tray 6, run obliquely apart from the later upper edges 11 of the side walls 8.
- the first rectangular approach is to use a horizontal one Frame with horizontal frame surfaces 13 to create the tub.
- the second rectangular extension 14, which is bent at right angles to the horizontal frame surface 13, serves to connect the floor pan 6 flush with the frame 2 of the safety workbench 1.
- On the later rear side wall 8 of the floor pan 6 close to the vertical Approach 14 two more right-angled approaches, which form a kind of hook after folding.
- edges along which the edge is folded are marked with a in FIG dashed line.
- the vertical side walls 14 have lower end edges, which run essentially horizontally in the finished floor pan 6.
- a larger hole, which serves as a collection area 9, is located on the extended one Line direction of the tip of the largest gusset 12, i.e. in one of the corners of the bottom region 7 the finished floor pan 6.
- FIG. 3 illustrates an isometric view of a floor pan 6 according to the invention in the finished state assembled condition.
- the floor pan 6 has a collection area 9, which is used here as an outlet is formed with a hole-shaped opening in the left front corner with respect to the work opening the safety workbench 1.
- the bending edges 10 run obliquely to the upper edges 11 of the side walls 8.
- the horizontal frame surfaces 13 are narrower than on the end faces of the floor pan 6 here on the long sides. Overall, the frame surface 13 has a substantially rectangular Contour, as they also have conventional floor trays.
