  • Publication number: 20250268131
    Abstract: A cutting unit for a lawnmower includes a cutting disc configured to rotate around a rotation axis during operation of the lawnmower and a cutting member freely pivotably arranged on the cutting disc around a pivot axis between a cutting position and a retracted position. The cutting member is configured to assume the cutting position by the centripetal force acting on the cutting member upon rotation of the cutting disc around the rotation axis. The cutting unit includes a stop assembly configured to stop pivoting movement of the cutting member when the cutting member reaches the retracted position. The angle between the cutting position and the retracted position is more than 180 degrees.

  • Patent number: 12257207
    Abstract: A pressure therapy device includes a pressure chamber, an inflatable padding, a seal, and a positioning mechanism. The pressure chamber has an opening arranged for admitting the inflatable padding and a limb of a user. The inflatable padding is inflatable to enclose and fix the limb in position. The seal covers the opening, including the inflatable padding and the limb to seal the pressure chamber from ambient atmospheric pressure. A pump unit is provided to generate a non-atmospheric pressure within the pressure chamber and includes a first valve system and a piston with safety release features for preventing unsafe pressure levels.
