Handle system for a handheld power tool
First Claim
1. A power driven hand tool comprising:
- a working member;
a main body comprising a housing with a drive unit configured to drive the working member;
a handle assembly comprising;
a handle comprising a protruding ring and a protrusion, the protrusion extending outwards in a substantially radial direction from the protruding ring;
a connecting part configured to connect the handle to the main body, the connecting part comprising;
a recess, wherein the recess is disposed in and extends around a portion of the connecting part and is configured to receive the protrusion of the handle when the handle is in a first rotational position, and wherein in the first rotational position, the handle is not configured to enable operation of the power driven hand tool;
a snap fastener configured to indicate that the protrusion of the handle has been inserted far enough into the recess to be rotated within the recess; and
a snap locking mechanism configured to secure the protrusion within the recess upon the handle being rotated to a second rotational position thereby connecting the handle within the connecting part, wherein when the handle is in the second rotational position, the handle is configured to enable operation of the power driven hand tool,wherein the second rotational position is located approximately 90 degrees from the first rotational position, andwherein the handle is configured to be detachable from the connecting part.

Abstract
The present invention relates to a method and devices for mounting and securing a handle (110) on a power driven hand tool (100) The power driven hand tool (100) is provided with a main body (104) comprising a housing (106) with a drive unit for driving a working member of the tool (100), a handle (110) for user operation of the tool (100), and a connecting part (112) for connecting the handle (110) with the main body (106). Further, a front end of the handle (110) may be inserted into a rear end of the connecting part (112) in a first rotational position in relation to the connecting part (112), and the handle (110) may be rotated into a second rotational position in relation to the connecting part (112). In the second rotational position, the handle (110) and the connecting part (112) are locked to each other by means of an automatic locking mechanism.
