Abstract

The suction tube (3) for mounting on the end (2) of a drill, has an inlet end (6) which is supported near the drill tip, so as to remove loose material cut by the drill tip. This tube is supported on the end of the drill body by a clamping member (1) which has a part (1A) for clamping to the body, and a recess (1BC) for a resilient bellows part (3) of the tube and a hole (1B) for the suction tube (4). A gripping handle can be attached to the clamping member, which can also incorporate a hole (15) for insertion of a member for controlling the depth of the drilled hole. The suction tube (4) is connected to a suitable suction device.

BOHRSTAUBABSAUGANSATZ Die Erfindung betrifft einen für jede handelsübliche Handbohrmaschine zu verwendenden Halterungsansatz zur Befestigung eines Staubsaugerstutzens. Der durch Wandbohrungen entstehende feine Staub kann mit Hilfe dieses Ansatzes über einen Staubsauger abgesaugt werden. Der Ansatz kann in der gewerblichen Wirtschaft ebenso verwendet werden wie in privaten Haushaltungen. DRILL DUST EXTRACTION APPARATUS The invention relates to one for each commercially available Hand drill to be used mounting attachment for attaching a vacuum cleaner nozzle. The fine dust created by drilling holes in the wall can be removed with the help of this approach vacuumed with a vacuum cleaner. The approach can be used in the commercial sector can be used as well as in private households.

Der jetzige, mir bekannte, Stand der Technik erlaubt das Absaugen Abfalimaterialien nur bei stationären Maschinen in der Industrie. Das sofertige Absaugen des Bohrstaubes wird erfindungsgemäß dadurch gelöst, daß bei diesem BOHRSTAUBABSAUGANSATZ die feste Verbindung von Handbohrmaschine und Staubsaugerabsaugstutzen hergestellt wird, sowie durch einen flexiblen Absaugbalg, welcher unmittelbar am Bohrloch anliegt.The current state of the art, known to me, allows suction Waste materials only for stationary machines in industry. The instant one Sucking off the drilling dust is achieved according to the invention in that in this DRILLING DUST SUCTION APPARATUS the fixed connection between hand drill and vacuum cleaner suction nozzle is established as well as by a flexible suction bellows, which rests directly on the borehole.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen Fig. 1 den BOHRSTAUBABSAUGANSATZ in der Draufsicht, die Bohrmaschine ist in die Öffnung 1A des Ansatzes eingeführt und der Staubsaugerstutzen ebenfalls in die daneben liegende Öffnung 1B. Der Absaugbalg 3 mit der Öffnung 6 liegt unterhalb (am Werkstück) der Bohrspitze.An embodiment is shown in the drawing and will described in more detail below. 1 shows the DRILLING DUST EXTRACTION APPROACH in FIG Top view, the drill is inserted into the opening 1A of the attachment and the Vacuum cleaner socket also in the opening 1B located next to it. The suction bellows 3 with the opening 6 is below (on the workpiece) the drill bit.

Fig. 2 zeigt die Seitenansicht des BOHRS-.AUBABSAUGANSATZES (1) mit eingeführter Bohrmaschine (2), dem Haltegriff 1D, dem Absaugbalg 3 und der Absiugdffnung 6.Fig. 2 shows the side view of the BOHRS-.AUBABSAUGANSATZES (1) with introduced drill (2), the handle 1D, the suction bellows 3 and the suction opening 6th

Fig. 3 zeigt die Vorderansicht des BOHRSTAUBABSAUGANSATZES mit den beiden Öffnungen 1A und 1B, der Führung 1E zur Aufnahme eines Abstandeinstellstiftes (Bohrlochtiefe) und dem Absaugbalgen 3 mit Öffnung 6, sowie Haltegriff 1D.Fig. 3 shows the front view of the DRILLING DUST EXTRACTION APPARATUS with the two openings 1A and 1B, the guide 1E for receiving a distance setting pin (Hole depth) and the suction bellows 3 with opening 6, as well as handle 1D.

Wie oben schon erwähnt, vereinigt der BOHRSTAUBABSAUGANSATZ einen handelsüblichen Staubsauger mit einer ebensolchen Handbohrmaschine. Der Ansatz verlängert den Staubsaugerabsaugstutzen durch den Balg 3 mit seiner Öffnung 6 bis zum Bohreransatzpunkt am Werkstück. Auf diese Weise werden die abgenommenen Späne sofort aufgesaugt.As already mentioned above, the BORING DUST EXTRACTION APPROACH combines one commercial vacuum cleaner with a hand drill of the same type. The approach lengthened the vacuum cleaner suction nozzle through the bellows 3 with its opening 6 to the drill attachment point on the workpiece. In this way, the removed chips are sucked up immediately.

Claims

Re: P 3006799.3 patent claims g drilling dust extraction attachment (1) identifies through the opening 1A for attachment to the respective drill.

2.) The approach (1) according to claim 1 is further characterized through the opening 1B for receiving the vacuum cleaner hose attachment.

3.) The approach (1) according to claim 1-2 is further characterized through the modified opening IBC to accommodate the flexible suction bellows 3.

4.) The approach (1) according to claims 1-3 is further characterized by the handle 1D.

5.) The approach (1) according to claims 1-4 is further characterized through the guide 1E to accommodate a drill hole depth adjustment rail.

6.) The approach (1) according to claims 1-5 is further characterized through the adapter 4 to accommodate any vacuum cleaner nozzle.

Generic term of the sub-claim: DRILLING DUST EXTRACTION APPROACH according to the claims 1 - 6 is further identified as a subclaim by the summary of three functions: 1. Extraction of drilling dust 2. Drill hole depth adjustment 3. Handle function.
