Abstract

A power tool includes a housing and a hook assembly. The hook assembly includes a hook support and a hook member. The hook support is rotatably attached to the housing for rotation about a first axis. The hook member has a shank portion and a hook portion. The shank portion defines a second axis that is transverse to the first axis and is configured to rotate with respect to the hook support about the second axis.

First claim

What is claimed is:

1. A power tool comprising:
a housing including a motor portion and a handle portion, the motor portion enclosing a motor and drive system configured to drive a work element, the handle portion extending from the motor portion and forming a grip for placement of a user's hand, the housing having a hook assembly retaining portion in an upper portion of the housing above the handle portion; and
a hook assembly including:
a hook support having a hook retaining member and a shaft portion extending from the hook retaining member, the shaft portion of the hook support being rotatably retained by the hook assembly retaining portion and configured to rotate with respect to the hook assembly retaining portion of the housing about a first axis;
a hook member having a shank portion and a hook portion, the shank portion defining a second axis and being rotatably retained by the hook retaining member of the hook support and configured to rotate with respect to the hook retaining member about the second axis, the second axis being transverse to the first axis,
wherein the hook assembly retaining portion of the housing is configured to retain the shaft portion of the hook support at a plurality of different angular positions with respect to the first axis, and
wherein the hook retaining member is configured to retain the shank portion of the hook member at a plurality of different angular positions with respect to the second axis,
wherein the hook assembly retaining portion is located directly above a side-to-side center of gravity and a front-to-back center of gravity of the housing,
wherein the hook assembly retaining portion comprises a bushing that defines a bore through which the shaft portion of the hook support extends, the bushing being retained in the upper portion of the housing,
wherein the shaft portion of the hook support includes a transition from a first diameter section to a second diameter section within the bushing, the first diameter section having a first diameter, the second diameter section having a second diameter, the first diameter being greater than the second diameter,
wherein the bushing defines a first opening to the bore in a first side of the bushing and a second opening to the bore on a second side of the bushing, the first opening having a size corresponding to the first diameter section, the second opening having a size corresponding to the second diameter section,
wherein the transition of the shaft portion forms a collar structure within the bushing,
wherein an inner wall of the bushing in which the second opening is defined forms a ledge structure that faces toward the collar structure, and
wherein a spring is arranged on the second diameter section of the shaft portion between the collar structure and the ledge structure.

2. The power tool of claim 1 , wherein the hook support is rotatable between a first position and a second position in relation to the housing,
wherein, when the hook support is in the first position, the shank portion is oriented along an outer surface of the housing, and
wherein, when the hook support is in the second position, the shank portion is oriented so as to extend outwardly from the housing.

3. The power tool of claim 1 , wherein the hook support is configured to move axially with respect to the hook assembly retaining member between a first axial position and a second axial position,
wherein, in the first axial position, the hook support is not allowed to rotate with respect to the hook assembly retaining member, and
wherein, in the second axial position, the hook support is rotatable with respect to the hook assembly retaining member.

4. The power tool of claim 3 , further comprising a biasing member configured to bias the hook support toward the first axial position.

5. The power tool of claim 1 , wherein the shank portion is configured to move axially with respect to the hook support between a first axial position and a second axial position,
wherein, in the first axial position, the shank support is not allowed to rotate with respect to the hook support, and
wherein, in the second axial position, the shank portion is rotatable with respect to the hook support.

6. The power tool of claim 5 , further comprising a biasing member configured to bias the shank portion toward the first axial position.

7. The power tool of claim 1 , wherein the housing defines a hook-shaped recess sized and positioned to receive the hook portion of the hook member.

8. The power tool of claim 1 , wherein the power tool comprises a circular saw.
