Abstract
Description
Im technischen Hilfeleistungseinsatz ist die Motorsäge ein bewährtes Einsatzmittel. Sie ist deshalb Ausrüstungsbestandteil vieler Feuerwehren, des THW usw. Motorsägen finden aber auch in der Forstwirtschaft, der Landwirtschaft und im Gartenbau bei professionellen wie auch privaten Anwendern eine weit verbreitete Verwendung.in the technical assistance application, the chainsaw is a proven resource. she is therefore equipment component many firefighters, the THW, etc. saws are also used in forestry, Agriculture and horticulture at professional as well private users a widespread use.
Die Motorsäge ist aber auch ein gefährliches Arbeitsgerät. Nach der Unfallverhütungsvorschrift (UVV „Allgemeine Vorschriften" GUV 0.1/VBG 1, §39) wird der Gebrauch von Motorsägen als gefährliche Arbeit eingestuft. Insofern gibt es mittlerweile sowohl aktive wie auch passive Sicherheitsvorkehrungen. Zu den ersten gehört die Sicherheitstechnik an der Maschine selbst, wie z.B. die automatische Kettenbremse, der Handschutz usw. Zu den eher passiven Sicherheitsvorkehrungen gehört vor allem die Schnittschutzeinlage in Schutzhosen, Beinlingen, Schutzjacken, Sicherheitsschuhen, Sicherheitshandschuhen usw. Sie dient dem Schutz gegen Schnitte, die von rotierenden Sägeketten verursacht werden.The chainsaw But it is also a dangerous tool. To the accident prevention regulation (UVV "General Regulations "GUV 0.1 / VBG 1, §39) becomes the use of chainsaws as dangerous Classified work. In this respect, there are now both active and also passive safety precautions. One of the first is safety technology on the machine itself, e.g. the automatic chain brake, hand protection, etc. Among the more passive safety measures belongs especially the protective layer in protective trousers, leggings, protective jackets, Safety shoes, safety gloves, etc. It is for protection against cuts caused by rotating saw chains.
Der Erfolg der passiven Sicherheitsvorkehrung Schnittschutzeinlage ist in der Tat messbar. In der Forstwirtschaft z.B. betrug die Unfallrate im Beinbereich vor der Einführung des Schnittschutzes ca. 29% aller Verletzungsarten. Nach vorliegenden Untersuchungen verhindern Schnittschutzhosen bei Kontakten mit der Sägekette in bis zu 84% aller Fälle eine Verletzung. Allerdings müssen dazu die Schnittschutzhosen auch angelegt werden, was zwar vorgeschrieben ist, in der Praxis aber nicht immer umgesetzt wird. Außerdem gilt es nach Lösungen zu suchen, die die Schutzrate von 84% auf annähernd 100% bringen.Of the Success of passive safety precaution is cut protection insert indeed measurable. In forestry e.g. was the accident rate in the leg area before insertion of cut protection approx. 29% of all types of injuries. After present Investigations prevent cut protection pants in contacts with the saw chain in up to 84% of all cases Injury. However, you have to In addition, the cut protection pants are also created, which is mandatory is, in practice but not always implemented. In addition, applies it for solutions looking to bring the protection rate from 84% to nearly 100%.
Die Ziele der vorliegenden Erfindung sind erstens, die Schutzkleidung mit Schnittschutzeinlage in der Weise mit der Motorfunktion des Gerätes zu verbinden, dass ohne eine funktionierende Verbindung die Maschine nicht in Betrieb genommen werden kann. Zweitens wird es auf der Grundlage der eben genannten technischen Mimik möglich sein, Vorrichtungen einzubauen, die bei Kontakt der Maschine mit der Schutzkleidung die Maschine ausstellen bzw. die Zündung unterbrechen. Dieser Kontakt kann direkt oder über ein besonders erzeugtes elektromagnetisches Feld mit Signalcharakter hergestellt werden.The The first objects of the present invention are protective clothing with cut protection insert in the way with the motor function of the equipment to connect that without a working connection the machine can not be put into operation. Second, it will be on the Basis of the aforementioned technical facial expressions be possible to install devices, when the machine comes into contact with the protective clothing, the machine Issue or the ignition interrupt. This contact can be direct or via a specially generated Electromagnetic field can be produced with signal character.
Im Einzelnen sieht es so aus, dass in die Sicherheitskleidung mit Schnittschutzeinlage, was auch Schuhe und Handschuhe mit einschließen kann, jeweils ein kleiner Sender mit Controller eingebaut ist, der die folgenden Features aufweist: geringe Reichweite, automatische Aktivierung durch Anziehen der Kleidung (z.B. durch Wärmesensor usw.), mechanische Aktivierung, funktionale Verbindung mit Signalübermittlungsträgern wie z.B. Draht- oder Glasfasergeflechten, die auf bzw. in die Oberschicht der Kleidung oder in die oberen Lagen der Schnittschutzeinlage eingelassen sind usw. In die Maschine ist ein Empfänger integriert, der bei Ausbleiben entsprechender Signale aus der Kleidung geeignete mechanisch und bzw. oder elektronisch erzeugte Unterbrechungen des Betriebs bewirkt. Beispiele dafür sind Zündungsunterbrechung, Unterbrechung der Kraftstoffzufuhr usw. In diesen Fällen kann also die Maschine nicht in Betrieb genommen werden.in the Individuals it seems that in the safety clothing with cut protection insert, which may include shoes and gloves, one smaller each Transmitter with controller is installed, which has the following features has: low range, automatic activation by tightening clothing (e.g., by heat sensor etc.), mechanical activation, functional connection with signal transmission carriers such as e.g. Wire or glass fiber braids, on or in the upper layer of Clothing or in the upper layers of the cut protection insert etc. are integrated into the machine, a receiver that is absent appropriate signals from clothing suitable mechanical and or electronically generated interruptions of the operation causes. Examples are Ignition interruption, Interruption of fuel supply, etc. In these cases can So the machine will not be put into operation.
Die in die Sicherheitskleidung eingelassenen Signalübermittlungsträger sind außerordentlich filigran und flexibel und mit dem Sender verbunden. Sie bilden an den oben angesprochenen Orten ein Muster aus Längs- und Querstreifen, die quadratisch, rechteckig, rautenförmig, in allen möglichen Rundformen usw. angeordnet sein können. In ihnen fließt permanent Strom. Bei Kontakt der rotierenden Kette mit einem solchen Signalübermittlungsträger wird der Stromkreislauf unterbrochen, was der Controller als Notsignal identifiziert und sofort über den Sender als Aufforderung an die Maschine weitergibt, den Betrieb unmittelbar zu unterbrechen, z.B. mittels Zündunterbrechung. Im normalen Bremsvorgang werden die Fasern der Schnittschutzeinlage bei Einschnitten in den Antrieb gezogen, worauf sie die Kettenbewegung blockieren. Durch eine Zündabschaltung müssen die Fasern der Schnittschutzeinlage die Kette der Säge nur noch abbremsen und nicht gegen die sonst weiterhin vorhandene Motorkraft ankommen. Somit wird die Gefahr verringert (s.o.), dass eine rotierende Kette durch die Schnittschutzeinlage schneidet und damit doch noch zu Verletzungen führt.The are in the safety clothing embedded signal transmission carrier extraordinarily filigree and flexible and connected to the transmitter. They are forming the above-mentioned places a pattern of longitudinal and horizontal stripes, the square, rectangular, rhombic, in all possible Round shapes, etc. may be arranged. In them flows permanently Electricity. Upon contact of the rotating chain with such a signal transmission carrier the circuit is interrupted, causing the controller as a distress signal identified and immediately over sends the transmitter as a request to the machine, the operation immediately to interrupt, e.g. by means of ignition interruption. In normal braking, the fibers of the cut protection insert pulled at incisions in the drive, whereupon they move the chain To block. By a Zündabschaltung have to the fibers of the cut protection insert the chain of the saw only decelerate and not against the otherwise existing engine power Arrive. Thus, the risk is reduced (s.o.) that a rotating chain through the cut protection insert cuts and thus still too Injuries leads.
Eine weitere zusätzliche Minimierung der Gefahr durch nachlaufende Motorsägen liegt in dem Ansatz, in die Säge, in das Schwert der Säge oder in ein zusätzliches Teil eine Antenne einzubauen oder diese Teile selbst als Antenne zu nutzen, um die Signale des elektromagnetischen Feldes zu empfangen. Dieses Feld wird u.a. von den in die Sicherheitskleidung eingelassenen Signalübermittlungsträgern erzeugt. Über einen Empfänger in der Säge werden die Signale ausgewertet. Bei Unterschreiten einer Grenzdistanz zwischen Signalübermittlungsträgern und Antenne werden Befehle an die Maschine ausgelöst.A additional Minimizing the risk of trailing chainsaws lies in the approach, in the saw, in the sword of the saw or in an additional one Part to install an antenna or these parts themselves as an antenna to receive the signals of the electromagnetic field. This Field is u.a. from those in the safety clothing Signal transmission carriers generated. About one receiver in the saw the signals are evaluated. When falling below a limit distance between signal transmission carriers and Antenna commands are triggered to the machine.
