Abstract

A hand-held power-tool footplate apparatus for portable power tools includes at least one main body unit configured to be removably positioned on a power-tool housing of a portable power tool, at least one housing abutment configured to abut against the power-tool housing, and at least one clamping surface located on a side that faces away from the housing abutment of the main body unit. The main body unit has a multi-point position fixing unit which has at least two pivot locking stops that differ from each other and that are configured to pivot angle lock the main body unit.

First claim

What is claimed is:

1. A hand-held jigsaw power tool system, comprising:
a portable power-tool including a power-tool housing, the portable power-tool configured to drive a machining tool in oscillation along a stroke direction that is parallel to a vertical axis of the portable power-tool housing, the power-tool housing including a first counterpart abutment located entirely in a contact plane, a second counterpart abutment located entirely in the contact plane, and a curved counterpart abutment located directly between the first counterpart abutment and the second counterpart abutment;
a first footplate apparatus that includes at least one main body unit positionable on the power-tool housing in only a right-angled orientation, the at least one main body unit including:
a first support surface configured to support the portable power-tool housing on a workpiece;
a first housing abutment surface located entirely in the contact plane and configured to abut the first counterpart abutment when the at least one main body unit is positioned on the power-tool housing to prevent movement of the at least one main body unit to any orientation other than the right-angled orientation, the first housing abutment surface parallel to the first support surface;
a second housing abutment surface located entirely in the contact plane and configured to abut the second counterpart abutment when the at least one main body unit is positioned on the power-tool housing to prevent movement of the at least one main body unit to any orientation other than the right-angled orientation, the second housing abutment surface parallel to the first support surface, and the second housing abutment surface configured to abut the second counterpart abutment when the first housing abutment surface abuts the first counterpart abutment;

a second interchangeable footplate apparatus including at least one further main body unit positionable on the power-tool housing in a plurality of angular orientations, the at least one further main body unit including:
a third housing abutment surface which is in a shape of a segment of a circular cylindrical ring, the third housing abutment surface configured to abut the corresponding curved third counterpart abutment of the power tool housing in the plurality of angular orientations,

wherein the first support surface of the at least one main body unit of the first footplate apparatus defines a support plane that is only orthogonal to the stroke direction when the at least one main body unit of the first footplate apparatus is positioned in the right-angled orientation, and
wherein the first support surface is always parallel to the contact plane when the at least one main body unit of the first footplate apparatus is positioned on the power-tool housing.

2. The hand-held jigsaw power-tool system according to claim 1 , wherein the second interchangeable footplate apparatus further comprises:
at least one bearing element configured to mount the at least one further main body unit to the power-tool housing, and further configured to permit movement of the second interchangeable footplate apparatus into at least one of:
a pivot angle locking position in which the second interchangeable footplate apparatus is fixed in position relative to a pivoting axis of the second interchangeable footplate apparatus; and
a pivot angle adjustment position in which the second interchangeable footplate apparatus is pivotable about the pivoting axis,

wherein the at least one bearing element is configured to translate along a movement axis that runs at least parallel to the second support surface and the pivoting axis.

3. The hand-held jigsaw power-tool system according to claim 1 , wherein:
the at least one main body unit further includes
a fixing unit configured to position the at least one main body unit in only the right-angled orientation when the at least one main body unit is positioned on the power-tool housing, and
at least one clamping surface located on a side of the at least one main body unit facing away from the first housing abutment surface and the second housing abutment surface,

the fixing unit is configured to generate a fixing force, via interaction with the at least one clamping surface, that acts on the at least one main body unit and that is oriented in a direction of the portable power-tool housing, for connecting the at least one main body unit to the portable power-tool housing.

4. The hand-held jigsaw power-tool system according to claim 1 , wherein:
the second interchangeable footplate apparatus further includes
a multi-point position fixing unit configured to fix the at least one further main body unit in a selected angular orientation of the plurality of angular orientations when the at least one further main body unit is positioned on the power-tool housing, and including a fixing element having at least one locking projection,
at least two locking stops formed in the at least one further main body unit that differ from each other, the at least one locking projection configured to abut at least one of the at least two locking stops when the at least one further main body unit is positioned on the portable power-tool housing.

5. The hand-held jigsaw power-tool system according to claim 1 , wherein the at least one main body unit further includes:
a centering element located directly between the first and the second housing abutment surfaces, the centering element configured to receive a post structure of the portable power-tool housing in positively locking fashion to further prevent movement of the at least one main body unit to any orientation other than the right-angled orientation when the at least one main body unit is positioned on the portable power-tool housing,
wherein the centering element is configured as a recess, and
wherein the post structure is located in the recess when the at least one main body unit is positioned on the portable power-tool housing.
