Abstract
An angle attachment for a rotary power tool includes a first assembly including a first shaft and a first gear and a second assembly including a second shaft and a second gear. The second gear engages the first gear and the central longitudinal axis of the second shaft is not collinear or parallel to the central longitudinal axis of the first shaft. The angle attachment further includes a member configured for removable coupling to a motor shaft of a rotary power tool and for removable coupling with the first assembly. At least a portion of the member is configured for insertion into a component of the first assembly.
Claims37
An angle attachment for a rotary power tool comprising:
- a first assembly including a first shaft and a first gear, the first shaft having a central longitudinal axis;
- a second assembly including a second shaft and a second gear, wherein the second gear engages the first gear and the second shaft has a central longitudinal axis, wherein the central longitudinal axis of the second shaft is not collinear or parallel to the central longitudinal axis of the first shaft;
- and
- a male connector configured for removable coupling to a motor shaft of a rotary power tool and for removable coupling with the first assembly;
- wherein at least a portion of the male connector is configured for insertion into an aperture provided in the first shaft or an aperture provided in a female connector coupled to the first shaft.
An attachment for a rotary power tool comprising:
- a first assembly comprising a first gear coupled to a first shaft;
- and
- a second assembly comprising a second gear coupled to a second shaft, the second gear intermeshing with the first gear;
- wherein a component of the first assembly includes an aperture for receiving therein at least a portion of a connector configured for removable coupling between a motor shaft of a rotary power tool and the component;
- wherein the attachment is configured to translate rotation of the first shaft to rotation of the second shaft, the first and second shafts each having axes of rotation and oriented such that the axis of rotation of the first shaft is neither parallel nor collinear with the axis of rotation of the second shaft.
An angle attachment for a rotary power tool comprising:
- a first assembly comprising a first gear provided on a first shaft;
- a second assembly comprising a second gear intermeshing with the first gear and provided on a second shaft, the first shaft and second shaft arranged such that they are not parallel or collinear with each other;
- and
- a member for removable coupling to the first assembly and to a drive shaft of a rotary power tool;
- wherein the first shaft includes an aperture for receiving therein a portion of the member;
- whereby rotation of the drive shaft of the rotary power tool may be communicated to the first assembly and to the second assembly by coupling the member to the drive shaft and to the first assembly.
A connector for coupling a rotary power tool to an attachment for the rotary power tool, the connector comprising:
- a shaft having a central longitudinal axis, the shaft configured for coupling to a drive shaft of a rotary power tool;
- and
- a head portion having a plurality of surfaces, at least a portion of the head portion having a generally polygonal cross-section transverse to the central longitudinal axis, at least one of the plurality of surfaces being convex with respect to the central longitudinal axis in the direction of the central longitudinal axis;
- wherein the head portion is configured for engaging a polygonal aperture provided in a component coupled to a rotary member of the attachment;
- whereby rotation of the drive shaft of the rotary power tool may be transmitted to the rotary member of the attachment utilizing the connector.
