Definitions
- the invention relates to a protective device for persons against the dangers emanating from arcs, in particular for the protection of the face, neck and chest area of the persons.
- arcing faults may occur. Physically, this is a plasma, ie an ionized gas of very high temperature. Therefore, these arcs, if they strike people or touch them, can cause severe burns.
- parts of the metal fittings of the electrical system can also be vaporized or due to the strong volumetric expansion associated with the sudden heating of the air, small metal particles are thrown around almost explosively, which in particular endangers the workers' eyesight.
- electricians are usually required to wear special personal protective equipment. First and foremost are protective gloves to protect the hands and forearms. Furthermore, wear a face shield to protect the face and especially the eyes.
- the face shield is usually made of a temperature-resistant polycarbonate disc as a protective screen.
- Such transparent protective screens are available as an independent protection device or as an accessory or in combination with a protective helmet.
- Such an independent protective shield which can be attached to the head of the electrician with a headband, for example, the company Paul Priceing GmbH & Co. KG (D-51688 Ohl / Wipper Requiredth, Germany) under the item number 5500 E.
- the combination with a protective helmet is particularly advantageous if anyway a protective helmet must be worn, for example, in electrical work on building put.
- Such a combination of protective helmet and face shield is also sold by Paul Preising GmbH & Co. KG under item numbers 5501 E (protective helmet) and 5500 ES (protective shield attachable to the helmet).
- Such protective screens do indeed protect the upper face area and are quite comfortable to wear. However, it may happen that a fault arc or hot gases generated by this hit under the screen. It may even happen that, through a kind of chimney effect, hot gases are "sucked" down the chest along the screen, causing significant burns in the chest, neck and lower part of the face.
- the actual facial area is also protected by a transparent protective screen.
- protective hoods and in particular full protective suits are rather complicated and, moreover, less comfortable than the simple protective umbrella. They are particularly unpleasant if you have to do sweaty work in them.
- protective devices are often dispensed with if they are complicated or uncomfortable for the user.
- the invention is therefore an object of the invention to provide a simple and comfortable to wear, but nevertheless effective protection device for the protection of the face, neck and chest area of a person against the outgoing of arc fault dangers.
- a protective device according to the independent claims 1 and 2.
- the basic idea of the invention is to combine a conventional transparent protective screen with a flexible protective bib attached to the screen and the area between the lower edge of the screen and the chest of the user covering and thereby protecting both from the arc itself and from this outgoing hot gases. In particular, the mentioned “chimney effect" is effectively prevented.
- the protective pad is designed so that it fits snugly against the chest of the user and thereby prevents a gap between the clothing and the protective pad is formed through which the arc could penetrate.
- a further advantageous embodiment of the invention is that the protective bib is detachably connected to the viewing screen.
- the screen and the protective pad can be cleaned separately and, if damaged, also be replaced or replaced separately.
- such a configuration is also suitable for retrofitting existing existing protective screens.
- the protective bib preferably has at least one connecting element at its lower end.
- such an element can be used to connect the protective bib to the user's clothing; on the other hand, such a connecting element can also serve to enable the protective window, when not in use, to be folded up and pulled over the protective strip over the head, e.g. to fix on a neck band of a safety helmet.
- the advantage of the invention is that it represents a very effective protection of its wearer against the danger posed by sturgeon bows.
- an arc in a conventional protective screen to temperatures above -400 0 C led in the face area, whereas in the same experimental arrangement with the protective device according to the invention only temperatures of less than 80 0 C occurred.
- Similar values can be achieved with full protection suits.
- the security device according to the invention is much easier and more comfortable to carry. Since it only covers the immediately endangered face, chest and neck area, but the rest of the neck and the back of the head are free, the protective device does not hinder the perspiration and is therefore particularly comfortable to wear.
- FIG. 2 shows a side view of a protective device according to the invention adapted to a protective device according to the prior art of Figure 1
- Figure 3 is a front view of a preferred embodiment of the invention protection device
- the protective device shown in Figure 1 is now commonly used by electricians. It consists of a protective helmet H, which carries the person to be protected P on her head and there can be fixed with the help of an adjustable neck band NB. A transparent rigid protective shirt S is attached to this helmet by means of a hinge SCH.
- the protective screen usually consists of a particularly resistant transparent plastic such as polycarbonate. As a result, the protective screen S is itself temperature-resistant and protects the person to be protected P both against the arc itself and against flying particles. Since the protective screen S is movably connected to the protective helmet H via the hinge SCH, it can easily be folded upwards over the protective helmet H when not in use, and then it does not interfere further.
- FIG. 2 A simple, yet comfortable protection against such effects is the example shown in Figure 2 in a side view of a protective device according to the invention. It consists first of a protective device according to the prior art, ie a helmet H with it attached transparent but rigid protective screen S, and on the other hand from a flexible apron LA, which is fastened by means of fastening elements BF at the lower end of the protective screen S and closes the gap between the lower end of the protective screen S and the body of the person to be protected P, but because of its flexibility, the person to be protected P not disabled. As a result, an electric arc can no longer strike under the protective screen S.
- a protective device according to the prior art ie a helmet H with it attached transparent but rigid protective screen S
- a flexible apron LA which is fastened by means of fastening elements BF at the lower end of the protective screen S and closes the gap between the lower end of the protective screen S and the body of the person to be protected P, but because of its flexibility, the person
- the rising of hot gases between the protective screen and the face of the person to be protected P is avoided and thus significantly reduces the temperature in the neck and face area. Since only the vulnerable front area of the person to be protected P is covered by the protective strip LA, the back of the head, the neck and the back of the neck but remain free, the freedom of movement of the person to be protected P is hardly limited and the Sch spaabschreib is little impaired.
- Both the protective screen S and the protective strip LA must be resistant to the particular thermal effects of an arc at least for a short time ...
- the material used for the protective screen S is primarily polycarbonate.
- Preopant is particularly advantageous because unlike many plastics under brief exposure to heat and even with flame contact does not ignite and does not melt and drips but instead swells and encrusted. In addition, Preopant remains flexible and supple even at low temperatures.
- the attachment of the protective pad LA on the protective screen S can be designed to be both rigid and detachable.
- Possible fastening elements BF such as adhesions, Velcro strips or pushbuttons (as shown in FIG. 2) are known to the person skilled in the art and need not be further explained.
- a detachable connection has the great advantage that the protective screen S and cover LA can be cleaned separately and if necessary can be replaced separately.
- Fig. 3 shows in a front view details of the protective strip LA and some advantageous developments of the protective device according to the invention.
- the protective effect of the device according to the invention depends crucially on the fact that no larger gap between the protective bib LA and the chest of the person to be protected P arises.
- the protective bib LA should therefore be designed so that it nestles as possible to the chest of the person P to be protected.
- the material of the protective pad LA should be as flexible and supple as possible. Furthermore, this can be supported, for example, by forming dart AN in the LA.
- darts AN are then given "predetermined bending points" so that the bib of the body contour of the person P to be protected can adapt better
- darts AN are just below the lower edge of the protective shield S and at the lower end of the protective pad LA, ie where Breast of the person to be protected P is touched, attached. Another possibility is to complain the guard LA at its lower end, so that it rests, for example, even in wind on the chest and not easily changes its position.
- This purpose can also serve fasteners VE preferably at the lower end of the protective strip LA, with the help of the protective strip LA can be fixed to the outer clothing of the person to be protected P.
- fasteners VE preferably at the lower end of the protective strip LA
- the protective strip LA can be fixed to the outer clothing of the person to be protected P.
- a Velcro connection into consideration.
- this also limits the freedom of movement of the person P to be protected somewhat more.
- a connecting element VE preferably at the lower end of the protective bib LA can also serve to fix the protective device according to the invention when it is not in use.
- the protective screen S can be folded up or over the head or helmet H.
- the protective bib is also pushed backwards, so that it rests on the head and possibly falls down on the back of the head.
- the protective bib LA can then be fastened to the protective helmet H or to the headband NB of the protective screen S or of the helmet H by means of the connecting element VE.
- an additional connecting element VE ⁇ for example in the form of a Velcro strip, can then be fastened to the protective helmet H or to the headband or neckband NB.
- an additional connecting element VE ⁇ is shown in the form of a glued to the helmet Velcro. This ensures that the protective device is always at hand when needed, but does not interfere with other work.
