Abstract

An angle drive attachment having an adjustable handle is provided. The angle drive includes an input shaft, an input shaft housing, a transmission, a handle mount, a handle, and an output socket. The handle allows the angle drive attachment to be adaptable to working environments having limited space or odd configurations. The input shaft rotates about the input axis of rotation and carried by the input shaft housing and drives the transmission. The output socket is connected to the transmission and rotates about an output axis of rotation and connects to a working bit. The handle mount mounts the handle to the input shaft housing. The handle, in cooperation with the handle mount, may be rotated about the input shaft housing, angled relative to the input shaft housing, and positioned axially linear along the input shaft housing.

Claims

1. An angle drive attachment, comprising:

a drive housing;

an input shaft carried for rotation in the drive housing for rotation along an input shaft axis, the input shaft having a workable end;

an output shaft carried for rotation in the drive housing for rotation along an output shaft axis that is angled relative to the input shaft axis, the output shaft having a connector for attachment to a work bit;

a handle mount slidably mounted on the drive housing and positionable thereon in a plurality of different linear and different angular positions;

a handle extending from the handle mount; and

a clamp releasably securing the handle mount to the drive housing.

2. The angle drive attachment of claim 1, further comprising a locking collar threadedly engaging the clamp, wherein the locking collar compresses the clamp against the drive housing.

3. The angle drive attachment of claim 2, wherein at least one of the locking collar and the clamp is tapered such that relative rotation between the locking collar and the clamp in at least one direction increasingly compresses the clamp.

4. The angle drive attachment of claim 2, wherein either the drive housing or the clamp includes a detented region and the other one of the drive housing and clamp includes a corresponding at least one engagement bump configured to selectively mate with the detented region to selectively prevent movement of the handle mount relative to the drive housing.

5. The angle drive attachment of claim 2, wherein the handle mount and clamp are integrally formed in a single unitary body, the handle mount projecting radially outward from the clamp, the clamp including a solid cylindrical portion and a threaded stub portion with axially extending slits therein, the thread stub portion receiving the locking collar.

6. The angle drive attachment of claim 5, wherein the solid cylindrical portion is of a larger diameter than the threaded stub portion, the solid cylindrical portion is supported for rotation by a cylindrical bearing surface of the drive housing, the unitary body is further axially movable relative to the drive housing, and further including means between the threaded stub portion and the drive housing for detentably locking the clamp to the drive housing.

7. The angle drive attachment of claim 1, further having the handle pivotally connected to the handle mount, the handle having a locking pin that engages a selected one of a plurality of angularly spaced apart locking cavities of the handle mount in an engaged position preventing pivotal movement of the handle relative to the handle mount and that is disengaged from the locking cavities in a released position allowing pivotal movement of the handle relative to the handle mount.

8. The angle drive attachment of claim 7, further comprising a biasing member resiliently biasing the locking pin toward engagement with the selected locking cavity.

9. The angle drive attachment of claim 8, wherein the biasing member and handle are arranged such that pulling on the handle acts against the biasing member and removes the locking pin from the selected locking cavity and releasing the handle allows the locking pin to insert into the selected locking cavity

10. The angle drive attachment of claim 9, further comprising a knuckle pivotally connected to the handle mount providing the pivotal connection between the handle and handle mount, the knuckle slidingly supporting the handle such that pulling on the handle slides the handle relative to the knuckle to remove the locking pin from the locking cavity.

11. The angle drive attachment of claim 10, wherein the handle includes at least one cavity housing at least one work bit.

12. An angle drive attachment, comprising:

a drive housing;

an input shaft carried for rotation in the drive housing for rotation along an input shaft axis, the input shaft having a workable end;

an output shaft carried for rotation in the drive housing for rotation along an output shaft axis that is angled relative to the input shaft axis, the output shaft having a connector for attachment to a work bit;

a handle mount mounted to the drive housing;

a handle pivotably connected to the handle mount via a hinge,

a releasable lock securing the handle to the handle mount, the handle being selectively locked by the releasable lock in a plurality of different positions between fully extended and retracted positions.

13. The angle drive attachment of claim 12, wherein the releasable lock includes a locking pin that releasably engages a selected one of a plurality of locking cavities.

14. The angle drive attachment of claim 13, further comprising a biasing member biasing the locking pin toward engagement with the selected locking cavity.

15. The angle drive attachment of claim 13, further comprising a knuckle pivotally mounted to the handle mount providing the hinge, the knuckle slidingly supporting the handle.

16. The angle drive attachment of claim 15, wherein the handle is slidable in a direction transverse to an axis of rotation of the knuckle.

17. The angle drive attachment of claim 15, further comprising a biasing member biasing a grip portion of the handle toward the knuckle and an engagement portion of the locking pin away from the knuckle and toward engagement with the selected locking cavity.

18. The angle drive attachment of claim 14, wherein the biasing member is a coil spring compressed between the locking pin and the knuckle.

19. The angle drive attachment of claim 13, wherein the plurality of cavities are angularly spaced apart relative to an axis of rotation of the hinge.

20. The angle drive attachment of claim 12, wherein the releasable lock and handle are configured such that pulling on the handle releases the releasable lock allowing the handle to be repositioned to one of the different positions between fully extended and fully retracted and releasing the handle locks the handle in the selected position.
