Abstract
The invention relates to a floor plate, in particular for portable, handheld tools with a combustion engine, an essentially flat surface with an continuous outer edge and at least one first opening with a related edge and a second opening with a related edge, wherein the at least one edge of an opening exhibits an element that projects at an inclined angle, which serves as a baffle plate to divert sparks and particles, and further that at least the continuous edge of the floor plate and/or the edge of at least one opening are at least sectionally beaded or pulled up.
Claims10
A portable, handheld tool comprising:
- an operating portion configured to operate on an object, the operating portion disposed in an operating plane;
- a drive that drives the operating portion in the operating plane;
- and
- a floor plate mounted to the operating portion, the floor plate including:
- an essentially flat surface, the essentially flat surface having a continuous outer edge, a back area and a front area, the back area and the front area being aligned along a longitudinal axis of the floor plate, the front area is positioned at one end of the floor plate along the longitudinal axis and the back area is positioned at an opposite end of the floor plate along the longitudinal axis;
- and
- one or more openings, each of the one or more openings having an edge, the edge of at least one opening of the one or more openings comprises a baffle plate that projects at an inclined angle over the at least one opening, the baffle plate configured to route flying sparks projecting from the operating portion operating on the object in the operating plane at the back area of the essentially flat surface,
- wherein the back area is positioned facing an acute angle side of the inclined angle and the baffle plate includes a major surface projecting towards the back area according to the inclined angle and extending in a plane transverse to the longitudinal axis, and
- the at least one opening whose edge has the baffle plate is aligned along the longitudinal axis between the back area and the front area, the at least one opening, the back area, the front area and the operating plane are positioned on the longitudinal axis so that the sparks are routed through the at least one opening whose edge has the baffle plate.

- a drive that drives the operating portion in the operating plane;
- and
- a floor plate mounted to the operating portion, the floor plate including:
- an essentially flat surface, the essentially flat surface having a continuous outer edge, a back area and a front area, the back area and the front area being aligned along a longitudinal axis of the floor plate, the front area is positioned at one end of the floor plate along the longitudinal axis and the back area is positioned at an opposite end of the floor plate along the longitudinal axis;
- and
- one or more openings, each of the one or more openings having an edge, the edge of at least one opening of the one or more openings comprises a baffle plate that projects at an inclined angle over the at least one opening, the baffle plate configured to route flying sparks projecting from the operating portion operating on the object in the operating plane at the back area of the essentially flat surface, wherein
- the back area is positioned facing an acute angle side of the inclined angle and the baffle plate includes a major surface projecting towards the back area according to the inclined angle and extending in a plane transverse to the longitudinal axis,
- the at least one opening whose edge has the baffle plate is aligned along the longitudinal axis between the back area and the front area, the at least one opening, the back area, the front area and the operating plane are positioned on the longitudinal axis so that the sparks are routed through the at least one opening whose edge has the baffle plate, and
- the essentially flat surface has a width that is narrower in the back area than in the front area.
