Abstract

A device for rotating tools on an axis which is not parallel to the rotational axis of a rotational driving source. Bevel gears and other mechanical means redirect forces from a rotational driving source, such as a portable rechargeable screwdriver, into forces capable of rotating tools to perform tasks on an axis not parallel to the rotational axis of the driving source. A rigid housing encloses most of the mechanical means for redirecting forces. A preferred embodiment comprises an adapter kit including a plurality of connectors for connecting the housing of the device to a plurality of differently sized powered driving sources. A method is also described in which tools may be rotated on an axis not parallel to the rotational axis of the rotational drive source.

Claims

1. A connector for coupling a housing of a rotational drive source to a housing of a rotational drive convertor, the connector comprising:

a connector body defining a channel therethrough and having a first end at a first opening of the channel and a second end spaced from the first end at a second opening of the channel, wherein the first end includes an engagement structure surrounding the first opening for engagement with the housing of the rotational drive convertor and wherein the second end includes a plurality of flexible slat portions; and

a collar disposed around the connector body that slides over outer surfaces of the plurality of flexible slat portions to drive inner surfaces of the plurality of flexible slat portions into frictional engagement with the housing of the rotational drive source.

2. The connector of claim 1, further comprising a skirt portion adjacent to the second end of the connector body that limits travel of the collar along the connector body.

3. The connector of claim 2, wherein the collar further includes an interior ledge for abutment with the skirt.

4. The connector of claim 1, wherein the inner surfaces of the plurality of flexible slat portions include textured portions.

5. The connector of claim 4, wherein the textured portions include knurled portions.

6. The connector of claim 1, wherein the connector body is cylindrically shaped.

7. The connector of claim 1, wherein the plurality of flexible slat portions further includes protrusions that engage an inner surface of the collar.

8. The connector of claim 7, wherein the inner surface of the collar includes depressions that engage with the protrusions to locate the collar on the connector body.

9. The connector of claim 1, wherein the collar includes a textured outer surface.

10. A connector for coupling a housing of a rotational drive source to a housing of a rotational drive convertor, the connector comprising:

a connector body defining a channel therethrough and having a first end at a first opening of the channel and a second end spaced from the first end at a second opening of the channel, wherein the first end includes flexible wedge shaped portions surrounding the first opening for snap-fit engagement with the housing of the rotational drive convertor and wherein the second end includes a plurality of flexible slat portions; and

a collar disposed around the connector body that slides over outer surfaces of the plurality of flexible slat portions to drive inside surfaces of the plurality of flexible slat portions into frictional engagement with the housing of the rotational drive source.

11. The connector of claim 10, wherein the connector body is cylindrically shaped.

12. A connector for coupling a housing of a rotational drive source to a housing of a rotational drive convertor, the connector comprising:

a connector body defining a channel therethrough and having a first end at a first opening of the channel and a second end spaced from the first end at a second opening of the channel, wherein the first end includes an engagement means that engages with the housing of the rotational drive convertor and wherein the second end includes a plurality of flexible slat portions having outer surfaces for receiving a slidable collar and inner surfaces for frictionally engaging with the housing of the rotational drive source; and

a collar disposed around the connector body that slides over the outer surfaces of the plurality of flexible slat portions.

13. The connector of claim 12, further comprising a skirt portion adjacent to the second end of the connector body that limits travel of the collar along the connector body.

14. The connector of claim 13, wherein the collar further includes an interior ledge for abutment with the skirt.

15. The connector of claim 12, wherein the inner surfaces of the plurality of flexible slat portions include textured portions.

16. The connector of claim 12, wherein the plurality of flexible slat portions further includes protrusions for engagement with an inside surface of the collar.

17. The connector of claim 16, wherein the inside surface of the collar includes depressions that engage the protrusions to locate the collar on the connector body.

18. The connector of claim 12, wherein the connector body is cylindrically shaped.
