Abstract
A skid plate for a robotic lawnmower, comprises an approximately circular plate with a central opening (13), for a hub (6b), and means of attachment (14, 15). The skid plate (2b) is attachable to the robotic lawnmower. An edge portion (7) of the circular plate is bent to extend transversally to a main plane (8) of the circular plate. An outer peripheral edge (11) thereof extends in a single plane. A robotic lawn mower comprises an electric motor connected to a rotatable cutting head (1b). The cutting head is connected to a cutting disk (3b) with at least one knife (4b) at its periphery. A skid plate (2b) as above is arranged below the cutting disk (3b).
Claims14
A skid plate for a robotic lawnmower, the skid plate comprising an approximately circular plate with a central opening, for a hub, and means of attachment, whereby the skid plate is attachable to said robotic lawnmower, wherein an edge portion of the circular plate is bent to extend transversally to a main plane of the circular plate, and an outer peripheral edge thereof extends in a single plane,
- wherein a cross section of the edge portion has, at least partly, a shape of a circle segment, and
- wherein the circle segment has a radius of 1 to 30 mm.
A skid plate for a robotic lawnmower, the skid plate comprising an approximately circular plate with a central opening, for a hub, and means of attachment, whereby the skid plate is attachable to said robotic lawnmower, wherein an edge portion of the circular plate is bent to extend transversally to a main plane of the circular plate, and an outer peripheral edge thereof extends in a single plane,
- wherein a central portion of the circular plate extends in a plane at a distance from the main plane of the circular plate, and
- wherein a distance between the plane of the central portion and the main plane of the circular plate is between 1 and 30 mm.
A robotic lawn mower comprising an electric motor connected to a rotatable cutting head, which is connected to a cutting disk with at least one knife at its periphery, and a skid plate arranged below the cutting disk,
- wherein the skid plate includes an approximately circular plate with a central opening, for a hub, and means of attachment, whereby the skid plate is attachable to said robotic lawnmower, wherein an edge portion of the circular plate is bent to extend transversally to a main plane of the circular plate, and an outer peripheral edge thereof extends in a single plane,
- wherein the at least one knife comprises multiple knives of the cutting disk that are arranged to extend above and partly radially outside of the skid plate, and
- wherein attachment means for attachment of the knives to the cutting disk extend below the level of the outer peripheral edge of the skid plate.
