Description

Beschreibung : Schutzvorrichtung an Kreissägen. Bei der Benutzung von Kreissägen werden ausschließlich Sägeblätter verwendet, die eine hohe Umfangsgeschwindigkeit haben. Außerdem sind die Zähne so scharf, daß nur die geringste unbeabsichtigte Berührung des die Kreissäge Bedienenden mit seinen Händen eine erhebliche Verletzung oder sogar eine Verstümmelung der Hand zur Folge hat.Description: Protective device on circular saws. When using Circular saws only use saw blades that have a high peripheral speed to have. In addition, the teeth are so sharp that only the slightest is unintentional Touching the circular saw operator with his hands is a serious injury or even maiming the hand.

Man hat daher die Kreissäge bisher mit Abdeckhauben versehen, die feststehend sind, und das Sägeblatt von allen Seiten frei lassen und daher ein fahrlässiges Berühren des Sägeblattes nicht verhindern. Diese Nachteile werden bei der Neuerung dadurch beseitigt, da8 die Ab- deckhaube, solange die Kreissäge nicht ira. Betrieb ist, dßrart auf dem Arbeitstisch ruht, daß das Sägeblatt von allen Seiten völlig abgedeckt ist. Soll die Kreissäge in Betrieb genommen werden, so bewegt ein vom Schneidegut betätigter Hebel, über eine besodnere Nebelanordnung, die das Sägeblatt vollkommen abdeckende Haube nach oben. Niese erfolgt aber nur so weit, daß das Schneidgut ohne Behinderung durch die Abdeckhaube an das Sägeblatt herangeführt werden, aber anderseits eine Verletzung des Arbeitenden an der Kreissäge durch Unachtsamkeit nicht erfolgen kann. Wenn das Arbeitsstück den Hebel nach unten drückt, wird durch eine besondere Hebelanordnung die Abdeckhaube soweit angehoben, daß nun das Arbeitsstück an da : 3 Sägeblatt herangeführt werden kann, nach fast er- folgenden Durchsägen des Arbeitsstücks wird nun der Hebel wieder frei, und bewegt sich in seiner Ausgangsstellung zurück, dabei geht die Abdeckhaube nach unten auf das Arbeitsstück und stellt eine vollständige Abdeckung des sägeblattes her. Gleichzeitig verhindert die Nase an der Abdeckhaube, daß die Hand, die dasArbeitsstück schiebt, in die umlaufende Säge kommt. Die wirkungsweise der Neuerung ist wie folgt ! ? ird das Sehneidcgut, beispielswaise sin Brett i das in der Längs- richtungaufgesagt werden soll, auf den Arbeitstisch der Abdeckhaube ge- nährt, ao druckt es den (Hebel) herunter, dadurch uird ein Hebelarm der drehbar gelagert ist, nach unten bewegt, und ein langer Hebelarm an seinen Ende nach oben drückt. Dadurch wird die mit des langen Hebelarm verbundene Abdeekhaube nach oben beegt Sie giebt dadurch das Sägeblatt soweit frei) daß das Brett gefahrlos durchgesägt uerden kann. Ist dies fast erfolgt, so giebt das Brett den (Hebel) wieder frei wodurchsieh gleichzeitig die Abdeckhaube aenkt, und die an der Ab- deckhaube befindliche Hase verhindert, daß der Bedienende mit seinen HUnden infolßc Unachtsnnkeit an das sich noch beeßende gägeblatt kant. 3s ist alao Gewähr geeen daß gefahrlos an dieser Kreissäge ge- arbeitet werden kann ; wobei noch hinzukommt daß die bdesKhaube die herumfliegenden Sägespäne auffängt. The circular saw has therefore hitherto been provided with cover hoods which are stationary and leave the saw blade free from all sides and therefore do not prevent negligent contact with the saw blade. These disadvantages are eliminated with the innovation because the cover, as long as the circular saw is not ira. Operation is, dßrart on that The work table rests so that the saw blade is completely covered on all sides. If the circular saw is to be put into operation, a lever actuated by the material to be cut moves the hood completely covering the saw blade upwards via a special fog arrangement. However, sneezing occurs only so far that the material to be cut can be brought up to the saw blade through the cover hood without hindrance, but on the other hand, injury to the person working on the circular saw through carelessness cannot occur. When the work piece pushes the lever down, the cover hood is raised by a special lever arrangement so that the Work piece to there: 3 saw blade can be brought up, after almost Following sawing through the workpiece, the lever is now free again and moves back to its starting position, while the cover goes down on the workpiece and completely covers the saw blade. At the same time, the nose on the cover prevents the hand pushing the workpiece from getting into the rotating saw. The effect of the innovation is as follows! ? If the cutting material, for example, is a board in the longitudinal direction is to be said, on the work table of the cover nourishes, ao it presses the (lever) down, thereby creating a lever arm which is rotatably mounted, moved downwards, and a long lever arm pushes up at its end. This is the one with the long Lever arm connected Abdeekhaube moved upwards the saw blade so far free) that the board can be sawn through safely can. When this is almost done, the board releases the (lever) again at the same time lowering the cover and the Cover hood located rabbit prevents the operator with his As a result, hand inattention to the yaw blade that is still eating edge. 3s is alao guarantee that this circular saw can be used safely. can be worked; with the addition of the bdesK hood catches the sawdust flying around.
