FORKLARING AF FREMBRINGELSENEXPLANATION OF PRODUCTION

Frembringelsen angår en forsats til opsamling af borestøv, hvor forsatsen omfatter et hulrum og mindst to huller, der 5 tillader passage af et roterende bor gennem hulrummet.The invention relates to an attachment for collecting drill dust, the attachment comprising a cavity and at least two holes which allow passage of a rotary drill through the cavity.

Det særlige ved forsatsen ifølge frembringelsen er, at forsatsen omfatter et ekstruderet hulprofil, der har en udvendig, plan flade, der omgiver det ene af hullerne.What is special about the attachment according to the invention is that the attachment comprises an extruded hollow profile having an exterior planar surface surrounding one of the holes.

Ved at lade forsatsen være udformet omkring en ekstruderet hulprofil kan forsatsen fremstilles på væsentlig biligere måde end de hidtil kendte forsatser.By leaving the attachment formed around an extruded hollow profile, the attachment can be made in a significantly cheaper way than the previously known attachments.

15 Det foretrækkes at forsyne den plane flade med et eftergive-ligt friktionslag, hvorved operatøren lettere kan holde forsatsen i fast position mod den overflade, hvori der bores. Samtidig formindskes risikoen for, at forsatsen kanter i hullerne, der omgiver boret, ikke rammer boret og derved 20 slår dette ud af position, eller at kanterne beskadiges af borets roterende, spiralformede kanter.It is preferred to provide the planar surface with a resilient friction layer so that the operator can more easily hold the support in a fixed position against the surface in which it is being drilled. At the same time, the risk is reduced that the rim edges of the holes surrounding the drill do not strike the drill, thereby knocking it out of position or damaging the edges by the rotating, helical edges of the drill.

Hulrummet i hulprofilet udnyttes til at opsamle borestøvet. Til det formål kan hulrummets nedadvendende åbning lukkes 25 med en prop, som nævnt i krav 3.The cavity in the hollow profile is utilized to collect the drill dust. For this purpose, the downward opening of the cavity can be closed with a plug as mentioned in claim 3.

TEGNINGENDRAWINGS

30 Et udførelseseksempel for frembringelsen skal herefter beskrives nærmere under henvisning til tegningen, hvor fig. 1 viser et lodret snit igennem forsatsen ifølge frembringelsen, og 35 fig. 2 viser et hulprofil til brug ved forsatsen.An embodiment of the invention will now be described in more detail with reference to the drawing, in which fig. 1 shows a vertical section through the attachment according to the invention, and FIG. 2 shows a hole profile for use at the attachment.

BESKRIVELSE AF UDFØRELSESEKSEMPLETDESCRIPTION OF THE EXAMPLE

5 Forsatsen ifølge frembringelsen er opbygget omkring et ekstruderet aluminiumsprofil 1, som er nærmere vist på fig. 2, og som foruden et gennemgående, cylinderisk hul 2 er forsynet med en forholdsvis stor, plan flade 3.5 The attachment according to the manufacture is built around an extruded aluminum profile 1, which is shown in more detail in FIG. 2, and which, in addition to a continuous cylindrical hole 2, is provided with a relatively large, flat surface 3.

10 Fladen 3 er belagt med skumgummi 4. Profilet 1 er nær sin ene ende 7 forsynet med huller 5, der tilsammen danner en gennemgående åbning for et bor 6. Eventuelt kan der i forsatsen være flere gennemgående åbninger til forskellige størrelser bor.10 The surface 3 is coated with foam rubber 4. The profile 1 is provided near its one end 7 with holes 5 which together form a through opening for a drill 6. Optionally there may be several through openings for different sizes of drill.

15 I den anden ende 8 af forsatsen er anbragt en plastprop 9 således, at borestøvet kan opsamles. I stedet for proppen 9 kan forsatsen, med en ikke vist tilslutningsanordning, tilsluttes en støvsuger eller beholder, så borestøvet effektivt 20 fjernes samtidig med boringen.15 At the other end 8 of the attachment is placed a plastic plug 9 so that the drill dust can be collected. Instead of the plug 9, the attachment, with a connection device not shown, can be connected to a vacuum cleaner or container, so that the dust is effectively removed at the same time as the bore.

Claims

An attachment for collecting drill dust, the attachment comprising a cavity (2) and at least two holes (5) allowing passage of a rotary drill (6) through the cavity and the attachment, which is new in that the attachment comprises a extruded hole profile (1) having an outer, flat surface (3) surrounding one of the holes (5).

The attachment according to claim 1, which is new in that the planar surface (3) is coated with a resilient friction material (4).

The attachment according to claim 1 or 2, which is new in that one of the openings of the cavity is openly closed by a plug (9).
