Bei den gebräuchlichen Handlaubsägebügeln wird das Laubsägeblatt an jedem Ende von zwei gegeneinanderpreßbaren Spannbacken gehalten, die an den Angriffsstellen gerauht oder mit senkrecht zum Sägeblatt verlaufenden Rippen versehen sind und ■won denen meistens eine fest mit dem Bügel verbunden zu sein pflegt. Wenn die Rauhun1· gen oder Rippen an den lösbaren Teilen abgmitzt sind, müssen diese ersetzt werden; die Beschaffung der Ersatzteile ist aber umständlich und kostspielig; wenn aber die mit dem Bügel fest verbundene Backe an den Angriffsstellen abgenutzt ist, ist der ganze Bügel unbrauchbar geworden.In the usual hand jigsaw hacks, the jigsaw blade is held at each end by two clamping jaws that can be pressed against one another, which are roughened at the points of attack or provided with ribs running perpendicular to the saw blade and where usually one tends to be firmly connected to the hanger. If the Rauhun gen 1 × or ribs are abgmitzt to the detachable parts, they must be replaced; the procurement of the spare parts is laborious and expensive; but if the jaw firmly connected to the bracket is worn out at the points of attack, the entire bracket has become unusable.
Es ist ferner bei Laubsägemaschinen bekannt, das Blattende zwischen die Arme eines in der Längsrichtung geschlitzten Bolzens oder eines in U-form gebogenen halbrunden Stabes zu schieben und die Arme des in eine zylinderförmige Bohrung der Blattführung eingesetzten Stabes oder Bolzens mittels einer Schraube zusammenzupressen; Rauhungen oder Rippen sind hier weder an den Angriffsstellen -noch außerhalb der Arme vorgesehen, so daß unter Umständen das Sägeblatt zwischen den Haltearmen oder gar letztere aus ihrem Lager herausgleiten können.It is also known in fretwork, the blade end between the arms of a in the longitudinal direction slotted bolt or a semicircular bent in a U-shape Push rod and the arms of the inserted into a cylindrical hole in the blade guide To compress the rod or bolt by means of a screw; Roughening or ribs are here neither at the attack points - still provided outside of the arms, so that the saw blade may be between the holding arms or even the latter can slide out of their bearings.
Gemäß der Erfindung werden diese Nachteile dadurch beseitigt, daß die gerippten Angriffsflächen der Backen mit einem in Splintform gehaltenen und gewellten Futter belegt werden, dessen Wellen senkrecht zum Sägeblatt liegen und in die Wellen der Backen eingreifen. Dieses Futter kann also nicht aus den. Backen herausgleiten, und die Wellen der Backen können nicht abgenutzt werden; dagegen ist das Futter leicht und bequem auszuwechseln, wenn seine eigenen Wellen abgenutzt sind.According to the invention, these disadvantages are eliminated in that the ribbed Attack surfaces of the jaws with a corrugated lining held in the form of a sapwood are occupied, whose waves are perpendicular to the saw blade and into the waves of the Engage jaws. So this feed cannot come from the. Jaws slide out, and the Shafts of the jaws cannot wear out; on the other hand, the feed is light and convenient to replace when its own shafts are worn out.
Ein weiterer Vorteil des Erfindungsgegenstandes liegt darin, daß die federnd auseinanderstrebenden Schenkel des splintförmigen Futters "beim Lösen der Klemmbolzenmutter die Backen auseinandertreibein und das Sägeblattende sofort freigeben.Another advantage of the subject matter of the invention is that the resiliently diverging Leg of the split pin-shaped chuck "when loosening the clamping bolt nut Drive the jaws apart and immediately release the end of the saw blade.
Ein Ausführungsbeispiel des Gegenstandes der Erfindung ist in der Zeichnung dargestellt.
.Es zeigen Fig. ι ein Futter in Seitenansicht undAn embodiment of the subject matter of the invention is shown in the drawing.
.Es show Fig. Ι a lining in side view and
Fig. 2 dasselbe im Schnitt,Fig. 2 the same in section,
Das- Klemmfutter α ist splintförmig gebogen und hat Rippen b, die senkrecht zum Sägeblatts liegen.The clamping chuck α is bent like a split pin and has ribs b which are perpendicular to the saw blade.
In der Spalte des Bügelarms, in die das Futter eingelegt wird, d.h. in den Innenflächen der Klemmbacken, sind entsprechende, an sich bekannte Rippen oder Wellen vorgesehen, in denen sich die Rippen bzw. Wellen des eingelegten Futters festlegen. Ebenso können in den Klemmbacken Aussparungen oder Kröpfungen angeordnet werden, die dem Splintkopf/als Lager dienen.In the column of the hanger arm in which the lining is inserted, i.e. in the inner surfaces the clamping jaws, appropriate ribs or waves known per se are provided, in which the ribs or waves of the inserted lining are fixed. as well recesses or offsets can be arranged in the clamping jaws, which correspond to the Cotter pin head / serve as a bearing.
Selbstverständlich werden in jedem Laubsägebügel zwei solcher Futter verwendet, von denen jedes ein Ende des Sägeblattes zu ' erfassen hat.Of course, two such chucks are used in each fretsaw, from each of which has to grasp one end of the saw blade.
Wird das Futter, dessen Schenkel federnd auseinanderstehen, zwischen die Klemmbacken gelegt und werden diese nach Einführung des Sägeblattendes zusammengepreßt, so erfassen die Rippen bzw. Wellen das Sägeblatt fest und doch etwas schmiegsam.Is the chuck, the legs of which are resiliently apart, between the clamping jaws placed and these are pressed together after the introduction of the saw blade end, so grasp the ribs or waves make the saw blade firm and yet somewhat pliable.
Löst man die Spannbacken, so streben die Schenkel des Futters auseinander, drükken also die Spannbacken auseinander und geben das Sägeblatt frei.If you loosen the clamping jaws, the legs of the chuck strive apart, press so the jaws apart and release the saw blade.
