Abstract
A U-shaped handle is attachable to a motor housing by a first projection on the end of the handle that engages a tab on the inside of the housing and by a second projection on the inside of the handle that engages a vent on the side of the housing. The projections are located on opposite sides of a fulcrum point such that applying a force to disengage either of the projections reinforces the engagement of the other projection, making the handle difficult to remove from the motor housing.
Claims16
A handle in combination with a motor housing, comprising:
- a main section;
- a pair of legs extending from the main section, each leg having first and second opposite sides, a fulcrum point on the first side, and first and second spaced projections on the second side, wherein the fulcrum point is disposed between the first and second projections;
- first receiving means on the motor housing for engaging the first projection;
- and
- second receiving means on the motor housing for engaging the second projection, wherein applying a force to disengage either of the projections from either of the first and second receiving means reinforces the engagement of the other projection with the other receiving means.
