Abstract

The sleeves (3,4) are spring loaded (7) at the machine (1) ends and telescope within limits set by stops (2,8). Bands of brushes (5,6) seal the gap between the two sleeves. The outer sleeve (4) presses against the work (13) and telescopes as the drill (1a) penetrates. It also has a connection (9) for the hose of a vacuum machine (9a).The bristle elements can be distributed in bands over the same circumference of the inner sleeve. ADVANTAGE - Prevents clogging of the drill.

Description

Die Erfindung betrifft eine Staubabsaugung für Bohr- und Meißelgeräte mit zwei oder mehreren ineinander verschiebbar gelagerten rohrförmigen Profilen.The invention relates to dust extraction for drilling and Chisels with two or more slidable stored tubular profiles.

Aus der DE-OS-24 53 791 ist ein Bohrgerät mit Staubabsaugung bekannt, das zwei teleskopartig ineinander verschiebbare, rohrförmige Profile aufweist. Die rohrförmigen Teile gleiten unter Verwendung eines Mittelstückes unmittelbar aufeinan­ der.From DE-OS-24 53 791 is a drill with dust extraction known that the two telescopically movable, has tubular profiles. The tubular parts slide using a center piece directly on top of each other the.

Die Lagerung von teleskopartig ineinander verschiebbaren rohrförmigen Profilen kann unter praxisgerechten Bedingungen beträchtliche Schwierigkeiten bereiten, vor allem dann, wenn die Profile jederzeit leicht gegeneinander verschiebbar sein sollen. Ablagerungen von Staub und anderweitige Verschmut­ zungen, wie auch harzige Fettgemische, führen vielfach zu Störungen.The storage of telescopically slidable tubular profiles can be used under practical conditions cause considerable difficulties, especially if the profiles can be easily moved against each other at any time should. Deposits of dust and other pollution tongues, like resinous fat mixtures, often lead to Disorders.

Der Erfindung liegt die Aufgabe zugrunde, die vorgenannten Mängel zu beseitigen und eine mit leicht ineinander ver­ schiebbaren Profilen ausgestattete, gegen Verschmutzung und Verkanten nicht anfällige, störungsfreie Staubabsaugung zu schaffen.The invention has for its object the aforementioned Eliminate defects and easily ver sliding profiles equipped, against pollution and Cant not susceptible to trouble-free dust extraction create.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß zu­ mindest auf einem Teil des sich überlappenden Lagerungsbe­ reiches auf der Außenseite des Innenprofils bürstenartige Elemente mit im wesentlichen senkrecht zur zugewandten Ober­ fläche des Außenprofils verlaufenden Borsten angeordnet sind.According to the invention the object is achieved in that at least on part of the overlapping storage area rich brush-like on the outside of the inner profile Elements with essentially perpendicular to the upper facing Surface of the outer profile arranged bristles are.

Die bürstenartigen Elemente schaffen dank ihren Borsten zwischen den rohrförmigen, teleskopartig ineinander ver­ schiebbaren Profilen eine multipunktuelle Auflage. Beim gegenseitigen Verschieben der Profile bewegen sich die Bor­ sten, wobei sie sich an die Oberfläche des Außenprofils an­ legen und eine leicht bewegliche und verschmutzungsunempfind­ liche Lagerung bewirken. Während die Borsten einerseits einen reinigenden Effekt hinsichtlich der davon betroffenen Oberfläche bewirken, kann sich andererseits zwischen den Borsten angesammelter Staub aufgrund der Beweglichkeit von selbst wieder lösen und aus dem Zwischenraum zwischen den Profilen herausfallen.The brush-like elements create thanks to their bristles between the tubular, telescopically ver sliding profiles a multi-point edition. At the  mutual movement of the profiles move the boron Most, they adhere to the surface of the outer profile insert and an easily movable and dirt-resistant effect storage. While the bristles on the one hand a cleaning effect on those affected Surface can, on the other hand, between the Bristles accumulated dust due to the mobility of solve again and out of the space between the Profiles fall out.

Die zweckmäßige Anordnung der bürstenartigen Elemente in bandförmigen Bereichen über den ganzen Umfang des Innenpro­ fils ergibt die Möglichkeit einer einfachen und wirtschaft­ lichen Herstellung des Lagerungsbereiches, beispielsweise unter Verwendung selbstklebender Hakenbänder (Klettband). Bei Verwendung solcher Hakenbänder wirken die Borsten mit ihren Haken wie Gleitkufen.The appropriate arrangement of the brush-like elements in band-shaped areas over the entire circumference of the interior pro fils offers the possibility of a simple and economical Lichen manufacture of the storage area, for example using self-adhesive hook tapes (Velcro). When using such hook tapes, the bristles contribute their hooks like skids.

Anhand der nachstehenden Figuren wird die Erfindung in bei­ spielhafter Form näher erläutert. Es zeigen:Based on the following figures, the invention is in at playful form explained in more detail. Show it:

Fig. 1 einen Längsschnitt durch eine an einem Bohrgerät angebrachte Staubabsaugung; Fig. 1 shows a longitudinal section through a drill mounted on a dust extraction;

Fig. 2 einen vergrößerten Ausschnitt aus Fig. 1 im Bereich der rohrförmigen Profile. Fig. 2 shows an enlarged detail from Fig. 1 in the region of the tubular profiles.

Fig. 1 zeigt den vorderen Teil eines Bohrgerätes 1 mit Bohrer 1a und Aufnahmeeinrichtung 1b, an dem eine aus zwei ineinander verschiebbaren rohrförmigen Profilen 3, 4 ge­ bildete Absaugvorrichtung angebracht ist. Dabei ist das Innenprofil 3 am Gehäuse des Bohrgerätes 1 befestigt und das Außenprofil 4 wird über eine Feder 7 an das zu bohrende Material 13 angepreßt. Der axiale Anpreßweg ist über die Anschläge 2, 8 einstellbar. Die Größe des Absaugraumes ergibt sich durch die Abmessungen von Bohrer 1a und Auf­ nahmeeinrichtung 1b. Fig. 1 shows the front part of a drill 1 with drill 1 a and receiving device 1 b, to which a ge from two telescoping profiles 3 , 4 formed suction device is attached. The inner profile 3 is fastened to the housing of the drilling device 1 and the outer profile 4 is pressed against the material 13 to be drilled via a spring 7 . The axial contact travel is adjustable via the stops 2 , 8 . The size of the suction chamber results from the dimensions of drill 1 a and 1 b on acquisition device.

Zwischen den Profilen 3, 4 sind bürstenartige Elemente 5, 6 angebracht. Außerdem weist das Außenprofil 4 einen Absaugstutzen 9 auf, der mit einem Schlauch 9a an einen an sich bekannten Staubsauger angeschlossen ist.Brush-like elements 5 , 6 are attached between the profiles 3 , 4 . In addition, the outer profile 4 has a suction nozzle 9 , which is connected with a hose 9 a to a known vacuum cleaner.

Fig. 2 zeigt eine vergrößerte Darstellung des bürstenarti­ gen Elementes 5 mit Außenprofil 4 im Schnitt und Innenpro­ fil 3 im Seitenriß. Das am Innenprofil 3 befestigte und über dessen gesamten Umfang bandförmig angeordnete bürsten­ artige Element 5 in Form eines Hakenbandes hält durch seine Borsten 5a das Innenprofil 3 und das Außenprofil 4 auf Di­ stanz und bewirkt dabei gleichzeitig zwischen den beiden rohrförmigen Profilen 3, 4 eine schmutzunempfindliche und gegen Verkanten und Blockieren unanfällige und dauerhafte Lagerung. Fig. 2 shows an enlarged view of the bürstenarti gene element 5 with outer profile 4 in section and Innenpro fil 3 in side elevation. The attached to the inner profile 3 and arranged over its entire circumference in a band-shaped brush-like element 5 in the form of a hook band holds through its bristles 5 a the inner profile 3 and the outer profile 4 on Di punch and simultaneously causes a dirt-insensitive between the two tubular profiles 3 , 4 and permanent storage that is not susceptible to tilting and blocking.
