Abstract

An attachment member (4) for connecting a hand grip with a housing part and a gearbox of an electric hand tool is formed of a flat base plate (11) for partitioning the housing part and the gearbox relative to the hand grip and formed with a first side (12) and a second side (13). Two passages (6.1, 6.2) form channels for guiding a fastener and extend perpendicularly to the second side (13) of the base plate (11). The attachment member (4) further comprises two air conveying elements (15.1, 15.2), which are arranged at an angle to the second side (13) and each has a curved deflecting section (22.1, 22.2), which projects from the second side on a radius (R) over an angular range (α). In addition, the attachment member (4) has a support for a detent spring (24) for a control knob for adjusting a gearing arranged in the gearbox.

Dependent claims

An attachment member (4, 31) for use in an electric hand tool for connecting a hand grip (3) of the tool to a housing part (2) and gearbox (5) of the tool, the attachment member comprising a flat plate (11) for partitioning the housing part (2) and the gearbox (5) relative to the hand grip (3), and having a planar first side (12) facing the housing part (2) and a planar second side (13) facing the hand grip (3), and at least one passage (10.1, 10.2) extending through said base plate substantially perpendicular to said first and second sides (12, 13) for receiving a fastening element;

at least one air conveying element (15.1;
15.2;
34.1) extending at an angle to said second side (13), and having at least one deflection circular section (22.1;
22.2) having a radius (R) and projecting from said second side (13) over an angle range (α);
and at least one support (23, 32) for supporting a detent spring (24) of a control knob (8) for adjusting a gear transmission located in the gearbox (5).
