Abstract

An adaptor for a dust extractor is provided including a housing having a top portion and a bottom portion, a first aperture formed in the top portion of the housing, a second aperture formed in the bottom portion of the housing, and an adaptor catch having a first end and a second end. The adaptor catch is vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing. The second end of the adaptor catch is accessible through the second aperture. A first biasing mechanism biases the adaptor catch towards the second catch position.

First claim

The invention claimed is:

1. An adaptor for a dust extractor comprising:
a housing having a top portion and a bottom portion;
a first aperture formed in the top portion of the housing;
a second aperture formed in the bottom portion of the housing;
an adaptor catch having a first end and a second end, the adaptor catch being vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing, the second end of the adaptor catch being accessible through the second aperture;
a first biasing mechanism arranged to bias the adaptor catch towards the second catch position; and
an engagement pin formed on the second end of the adaptor catch and being engageable with a recess formed within a top portion of a catch of the dust extractor.

2. An adaptor according claim 1 , further comprising at least one rail formed on the underside of the housing and being slidingly engageable with at least one guide formed on the dust extractor.

3. An adaptor for a dust extractor comprising:
a housing having a top portion and a bottom portion;
a first aperture formed in the top portion of the housing;
a second aperture formed in the bottom portion of the housing;
an adaptor catch having a first end and a second end, the adaptor catch being vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing, the second end of the adaptor catch being accessible through the second aperture;
a first biasing mechanism arranged to bias the adaptor catch towards the second catch position; and
a pin formed on a side of the adaptor catch extending away from the adaptor catch.

4. An adaptor according to claim 3 , wherein the pin extends perpendicularly away from the adaptor catch.

5. An adaptor according to claim 4 , wherein the pin extends through an elongate vertical slot formed through a side wall of the housing where it is accessible by a user.

6. An adaptor according to claim 3 , wherein the pin extends away from the adaptor catch into a chamber, the adaptor further comprising:
a bar having a first end and a second end, the bar being slidable between a first bar position, where the first end of the bar is located away from the pin, and a second bar position, where the first end of the bar extends into the chamber and into engagement with the pin; and
a cam formed on the first end of the bar, the cam being engageable with the pin;
wherein, as the bar is moved from the first bar position to the second bar position, the cam engages the pin and moves the adaptor catch from the second catch position to the first catch position.

7. An adaptor according to claim 6 , wherein the bar is slidable in a direction perpendicular to that of the adaptor catch.

8. An adaptor according to claim 6 , further comprising a second biasing mechanism which biases the bar to the first bar position.

9. An adaptor according to claim 6 , wherein the second end of the bar projects through an aperture formed through a wall of the housing, where it is accessible by a user, when the bar is in the first bar position.

10. An adaptor according to claim 9 , wherein the second end of the bar is flush with or located inside of the housing surrounding the aperture formed through the wall of the housing when the bar is in the second bar position.

11. An apparatus comprising a dust extractor and an adaptor according to claim 1 ,
wherein the adaptor comprises:
a housing having a top portion and a bottom portion;
a first aperture formed in the top portion of the housing;
a second aperture formed in the bottom portion of the housing;
an adaptor catch having a first end and a second end, the adaptor catch being vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing, the second end of the adaptor catch being accessible through the second aperture; and
a first biasing mechanism arranged to bias the adaptor catch towards the second catch position;

and where the dust extractor comprises:
a dust extractor housing having an engagement region for receiving at least part of the housing of the adaptor when the adaptor is connected to the dust extractor; and
a latch mechanism comprising:
a latch moveably mounted within the dust extractor housing and moveable between a first latch position and a second latch position;
a biasing mechanism biasing the latch towards the first latch position; and
at least one dust extractor catch attached to the latch, wherein, when the latch is in the first latch position, the dust extractor catch projects the engagement region and, when the latch is in the second latch position, the dust extractor catch is located outside of engagement region;
wherein the at least one dust extractor catch comprises a chamfer that is arranged so that, when the latch is in the first latch position and a part of the adaptor enters the engagement region for connection to the dust extractor, the chamfer sliding engages the second end of the adaptor catch and moves the adaptor catch from the second catch position towards the first catch position against the biasing force of the first biasing mechanism.

12. An apparatus according to claim 11 , wherein, when the adaptor is connected to the dust extractor, the chamfer sliding remains drivingly engaged with the second end of the adaptor catch.

13. An apparatus according to claim 11 , wherein, when the adaptor is connected to the dust extractor, movement of the latch from the first latch position to the second latch position moves the adaptor catch from the first catch position to the second catch position.

14. An apparatus according to claim 11 , wherein a recess is formed in a tip of the at least one dust extractor catch; and
wherein the adaptor catch comprises an engagement pin formed on the second end of the adaptor catch engaging with the recess when the chamfer slidingly engages the second end of the adaptor catch.

15. An apparatus according to claim 11 , wherein the engagement region comprises a recess formed within a section formed within the dust extractor housing and/or a space proximate and above a top wall of the dust extractor housing.

16. An apparatus according to claim 11 , wherein the adaptor further comprises at least one rail formed on the underside of the housing and the dust extractor comprises at least one guide, and wherein, when the at least one part of the housing of the adaptor enters the engagement region, the at least one rail slidingly engages with the at least one guide to attach the adaptor to the dust extractor.

17. A system comprising a drill and an apparatus in accordance with claim 11 , wherein the drill comprises:
an outer housing;
at least one recess formed in the outer housing arranged to receive the adaptor catch when the adaptor is connected to the dust extractor, the drill is mounted on the dust extractor, and the latch is in the first latch position.

18. A system according to claim 17 , wherein the drill further comprises at least one surface engageable with a chamfer of the adaptor catch when the adaptor is connected to the dust extractor and the drill is moved into the engagement region.
