Abstract
A power tool (2) includes a motor (22) pivotally mounted within the housing of the tool. The tool is able to accept any one of a plurality of attachment members (44, 46, 48).
Claims20
A power tool comprising:
- a body portion defining a handle;
- a motor mounted within the body portion;
- a drive member driven the motor and defining an axis;
- the body portion defining an opening;
- a removable head received within the opening, the removable head operatively receiving the output member;
- the body portion defining an attachment head interface abutting the removable head, the interface defining a rigid and substantially continuous surface having a first portion and a second portion, the first portion being generally disposed in a first plane and oriented generally perpendicular to the axis, the second portion being generally disposed in a second plane at an angle to the first plane, the first portion defining an upper part of the opening, the second portion extending downwardly and forwardly relative to the first portion and defining a second part, the first portion upwardly terminating at an upper surface of the body portion, the second portion downwardly terminating at a forward surface of the body portion.
3 more elements
A power tool comprising:
- a main body portion defining an opening;
- a motor mounted within the main body portion;
- an output member rotatably driven about an axis by the motor;
- at least one removable head received with the opening, the at least one removable head operatively receiving the output member;
- and
- the main body portion including a continuous interface surface about a periphery of the opening, the interface surface including a first portion and a second portion, the first portion being generally planar and oriented substantially perpendicular to the axis, the second portion being angled with respect to the first portions the first and second portions being rigid;
- the at least one removable head having a cooperating rigid surface abutting the interface surface;
- whereby the first and second portions are both engaged by the cooperating rigid surface of the at least one removable head through movement of the at least one removable head in a direction parallel to the axis.
5 more elements
A power tool comprising:
- a body portion defining a handle;
- a motor mounted within the body portion;
- a drive member driven the motor and defining an axis;
- the body portion defining an opening;
- a removable head received within the opening, the removable head operatively receiving the output member;
- the body portion defining an attachment head interface matingly abutting the removable head, the interface defining a rigid and substantially continuous surface having a first portion and a second portion, the continuous surface having a non-circular shape which prevents relative rotation between the body portion and the tool head.
3 more elements
A power tool comprising:
- a body portion defining an opening;
- a motor mounted within the main body portion;
- an output member rotatably driven about an axis by the motor;
- a removable head at least partially received in the opening, the removable head operatively receiving the output member;
- the opening being bordered by a flange portion and a confronting portion, the flange portion being formed in at least two distinct planes, a first one of the planes being disposed generally perpendicular the axis of the output member, a second one of the planes being disposed at an angle relative to the axis of the output member so as to intersect the first one of the planes, the confronting portion being sized to receive;
- the removable head having a cooperating surface that continuously abuts the flange portion.
