Auxiliary handle
An auxiliary handle is disclosed. The auxiliary handle has a frame-shaped grip which has a grip bar for gripping by a user, a crossbar, and two flanks connecting the grip bar to the crossbar. A loop-shaped clamping element is fastened to the crossbar for placing on a neck of a handheld machine tool. A clamping mechanism serves for clamping the element about the neck of the handheld machine tool. The frame-shaped grip has a frame-shaped base body molded from a first plastic, which has a solid body joint in each of the regions of the flanks. A casing made from a second plastic encloses the fame-shaped base body in the region of the grip bar and the solid body joints.
1. An auxiliary handle for a handheld machine tool, comprising:
a frame-shaped grip which has a grip bar for gripping by a user, a crossbar, and two flanks connecting the grip bar to the crossbar; and
a clamping element attached to the crossbar;
wherein the frame-shaped grip has a frame-shaped base body injection-molded of a first plastic and wherein the frame-shaped base body has respective solid body joints in regions of the two flanks;
wherein a casing of a second plastic surrounds the frame-shaped base body in a region of the grip bar and the solid body joints.
2. The auxiliary handle according to claim 1 , wherein the solid body joints are completely surrounded by the casing.
3. The auxiliary handle according to claim 1 , wherein the grip bar is pivotable in relation to the crossbar about a pivot axis which runs through the solid body joints.
4. The auxiliary handle according to claim 3 , wherein the solid body joints are rigid along the pivot axis.
5. The auxiliary handle according to claim 3 , wherein the solid body joints, in a plane perpendicular to the pivot axis, is filled completely with the first plastic and the second plastic and wherein a proportion of the first plastic is between 10% and 20%.
6. The auxiliary handle according to claim 1 , wherein the solid body joints are formed by a constriction of the frame-shaped base body along a direction perpendicular to a plane stretched from the grip bar and the crossbar.
7. The auxiliary handle according to claim 1 , wherein a dimension of the frame-shaped base body perpendicular to a plane stretched from the grip bar and the crossbar in a region of the solid body joints is between 10% and 25% of a dimension of the frame-shaped base body perpendicular to the plane in a region of the grip bar.
8. The auxiliary handle according to claim 1 , wherein the solid body joints are wavy.
9. The auxiliary handle according to claim 1 , wherein the frame-shaped grip in a region of the solid body joints has a circular or elliptical cross-section with a maximum difference of a large semi-axis to a smaller semi-axis of 10%, wherein the cross-section is completely filled by the frame-shaped base body and the second plastic.
