Patent number: 11723313Abstract: An electric pole pruner having a spring returned cutting head and equipped with a drive unit having an electric motor coupled to a drum via an epicyclic gear assembly is configured to reduce rotation speed and to increase torque. A string element is coupled to the drum of the drive unit, and to the cutting head so as to actuate the cutting head. The pole pruner further includes a locking arrangement to selectively lock or release a ring gear of the gear assembly so as to convert rotation of the electric motor into rotation of the drum when the ring gear is locked, and to convert rotation of the drum into rotation of the ring gear when the ring gear is released.Type: GrantFiled: August 20, 2020Date of Patent: August 15, 2023Assignee: Fiskars Finland Oy AbInventors: Olavi Lindén, Jan Lindén

Patent number: 11654585Abstract: A shearing tool has a first unit with a first blade, rotatably coupled to a second unit with a second blade, at a first pivot having a first pin, so that displacement of the first blade relative to the first pin in a direction parallel with a first rotational axis is prevented, and the handle is connected to the second blade so that rotational movement of the handle relative to the second blade about a second rotational axis is allowed. The second rotational axis is defined by a second pivot interacting with the second blade and the handle at a distance from the first rotational axis in a direction away from a cutting edge contact point. When the shearing tool moves from an open to a closed position, the second blade is driven towards the first blade at the contact point for increasing the cutting capacity of the shearing tool.Type: GrantFiled: June 11, 2019Date of Patent: May 23, 2023Assignee: Fiskars Finland Oy AbInventor: Erkki Olavi Lindén

Patent number: 10398088Abstract: Pruning shears include a cutting head with a spring-biased blade; a driving line connected at a first end to the blade; an elongated body; a handle; and a frusto-conical shaped wheel connected rotatably to the handle. The diameter of the wheel at a first end being smaller than the diameter at a second end. The line is wound into a spiral groove around the wheel at the first end; a second end of the line is attached to a second end of the elongated body; and the line wound around the wheel moves toward the second end of the wheel when unwinding a part of the line from around the wheel and winding another part of the line around the wheel for decreasing the distance between the first and second ends of the line, resulting in movement of the blade in relation to the jaw, when the handle is moved.Type: GrantFiled: June 2, 2017Date of Patent: September 3, 2019Assignee: Fiskars Finland Oy AbInventors: Olavi Lindén, Jan Lindén

Patent number: 10091946Abstract: Pruning shears include a cutting head with a spring-biased blade pivotally connected to a jaw and arranged to sever a workpiece received in a bight formed by the jaw. A drive mechanism is connected to the cutting head and an elongate housing is connected to the drive mechanism. The drive mechanism includes a rotation preventer for preventing rotation of a second pulley in relation to the drive mechanism when a drawing torque is applied to the second pulley. The drawing torque is greater than a threshold torque, resulting in a second pulley being stationary in relation to the drive mechanism and the first pulley rotating in relation to the drive mechanism.Type: GrantFiled: September 26, 2016Date of Patent: October 9, 2018Assignee: Fiskars Finland Oy AbInventors: Olavi Lindén, Jan Lindén
