Definitions
- the invention relates to a safety workbench with a work opening, the lower limit is formed by a boundary plate in the ventilation openings for generating a vertical air flow are arranged and with at least one in the lower region of the working opening arranged armrest.
- Safety cabinets are general, for example from the company brochure "Biological Heraeus Lamin Air HB and HBB "safety cabinets” from Heraeus Instruments GmbH known.
- Safety cabinets of this type are designed so that they are parallel to the work opening a vertically directed air flow can be generated, which prevents a kind of veil, that contaminated atmosphere from the work area of the safety cabinet through the work opening got outside.
- These are on the lower, essentially horizontal Boundary plate of the working opening provided ventilation openings through which a vertical downward airflow is generated.
- the lower boundary plate is therefore used as a support surface used for the forearms.
- the boundary plate on the outside, for Edge facing the operator must be rounded.
- the boundary plate is shown in the Kind used as an armrest, the ventilation openings are covered by the arms, so that laminar air flow is prevented. This will make this air flow function disturbed.
- the boundary plate can be cleaned only with relatively great effort.
- GB 21 12 927 A is a safety workbench with one arranged at the lower edge of the opening Armrest known.
- the object of the present invention is based on the known prior art to create a safety workbench where the armrests are easy to decontaminate and do not significantly reduce the effective cross section of the ventilation openings.
- the task for a safety workbench characterized in the introduction is thereby achieved solved that the armrest formed as a separate component and detachable in the boundary plate is held in the ventilation openings and has a support plate and supports, the supports are held at the lower ends of the ventilation openings.
- a separate Armrest can also be decontaminated separately and therefore very easily, on the other hand, a separate armrest can be designed ergonomically, as it is not subject to the design principle of the boundary plate. Furthermore, it is avoided that by placing the arms on the boundary plate, the ventilation openings are uncontrolled be locked; with a separate armrest, the number of closed ventilation openings be kept to a minimum.
- the ventilation openings are designed as slots and that several Rows of slots arranged parallel to each other to form a grid are arranged side by side.
- Such an arrangement enables an almost unlimited one Variability in the arrangement of the armrests. Due to the slot-like design ensures a good fixation, since the supports within the slots are in the longitudinal direction the slots are slidable and therefore easy to install, the movement is transverse to the slot however, set narrow limits, especially if the width of the supports is only slightly smaller than the width of the slots.
- the work opening of the safety workbench is at its lower end through a boundary plate 1 limited.
- the boundary plate 1 is arranged essentially horizontally and evenly and has slot-shaped ventilation openings 2, through which a vertically upward directed air flow is guided.
- the armrest 3 has a support plate 4, which approximately Is arranged 50 mm above the boundary plate 1 and with supports 5 in the boundary plate 1 is supported.
- the supports 5 point vertically down to the boundary plate 1 and are then one angled horizontal section 6, which rests on the boundary plate 1. At the end of this first horizontal section 6, the supports 5 are each through a ventilation opening 2 angled downwards and form a second one below the limiting plate 1 horizontal section 7, which rests on the boundary plate 1 from below.
- the two horizontal ones Sections 6; 7 can be arranged in a step-like manner, as shown in Figure 2 is shown, or also U-shaped. However, a U-shaped arrangement is less stable.
- the armrest 3 is made of stainless steel and is therefore easily autoclavable.
- the supports 5 are formed from round steel and have a diameter which is only slightly smaller than the width of the slot-shaped ventilation openings 2, so that the armrest 3 also in lateral Direction is well locked. Accordingly, the supports can also be formed from flat material his.
