A hand-held cutting device (10) including an elongated member (45) graspable along a portion thereof by an operator, a trimmer head (25) disposed at one end of the elongated member, and a power unit operably coupled to the trimmer head to selectively cause rotation of the trimmer head, wherein the trimmer head comprises a line holding assembly (110) to hold and selectively release the trimmer line (70) and a housing to house the line holding assembly, wherein the line holding assembly includes a core (340) having a first portion (342) and a second portion (350), and a spool (130) configured to hold trimmer line that is operably coupled to the core, and wherein the second portion of the core is non-rotatably fixed to the first portion of the core when the trimmer head is in an at-rest state, and is rotatable with respect to the first position of the core when the trimmer head is in an in-use state and rotating.

The present invention is directed to a string trimmer line feeding mechanism having a sliding lever that locks a spool relative to the spool housing, and only feeds additional cutting line when the user actuates a button. This brakes a motor, which generates a force acting on the spool to move the lever into an unlocked position, allowing the spool to rotate relative to the spool housing and feed additional cutting line.

A trimmer head for use with either clockwise or counterclockwise trimmer heads, including the use of a bidirectionally dispensing spool. Various locations of passages straight through the trimmer head and spool are shown along with various locations of components of the ratcheting mechanism to allow for winding of the trimmer line on the trimmer head and for limiting the amount of line dispensed during “bumping” of the trimmer head knob on the ground. Additionally, an extended funnel into the passage can be provided to facilitate entrance of trimmer line into the funnel even when the line is not perfectly straight. Also, spokes can be used in place of the flanges of the spool to save material and cost, while still providing a guide and barrier between the line store areas.

The grass cutting head (1), configured for rotation around a rotation axis, comprises a housing (3) for a cutting line (F); a space (5) inside the housing for winding a stock of cutting line; at least one hole (3B) in a side wall (3A) of the housing (3), through which the cutting line (F) passes from the inner space (5) towards the outside of the housing; At least one cutting blade (21) with at least one cutting edge (23) is associated with the housing (3) of the grass cutting head (1).

Cable support and extraction device for brushcutting machines, comprising a first part (1) with a first hollow shaft (1.1) for the connection of a drive shaft, a cover (3) and a side surface (4) with a through hole (5) and two diametrically opposed slots (6) for the passage of the ends of a cable (7); a second part (2) to fit inside the first part, with a second hollow shaft (2.1) hollow, allowing the passage of the first shaft (1.1) inside it and the winding of the cable (7) around it, between a first stop (8.1) with a flange (9) oriented towards a second stop (8.2) opposite; a retractable pin (10) in the flange (9), which has an engaged position in the hole (5) and a disengaged position for the free rotation of the second piece (2), and; means of actuating.

A strand trimmer and method of use thereof. The strand trimmer includes a pair of pivotable arms each having a motor, a follower wheel, and a cutter-spindle assembly disposed thereon. The arms are biased toward one another and are guided by the follower wheels to pivot around obstacles passing between the arms. The motor rotates the cutter-spindle assembly to move cutting strands extending therefrom through a cutting path with sufficient rotational velocity to cut vegetation. The cutter-spindle assembly includes a spool and a strand-feed mechanism. The spool is oriented to rotate about a horizontal axis. The strand-feed mechanism includes a solenoid actuated plunger within a shaft of the cutter-spindle assembly. The plunger engages the spool to control rotation of the spool and thereby feeding out of incremental lengths of the strand.

An improved guard is provided for hand-held cutting edge devices such as lawn trimmers. The guard extends beyond the cutting plane formed by the circular travel of the flexible cutting element. The extended guard protects against foreign objects being propelled by the cutting element, possibly causing damage or physical harm. A cutter may be provided inside the perimeter of the guard, extending into the plane formed by the cutting element to function as a cutter for setting the length of the cutting element being used. The guard may be formed as a single piece or as a composite which when assembled encircles the center assembly of the cutting element.

A multi-mode trimmer head for use with an outdoor handheld tool such as a string trimmer, brush cutter, or the like is provided. The trimmer head includes an upper housing, lower housing, bump head, spool, and a spring. The spool includes a first pair of apertures configured to receive a pair of flexible trimmer lines to provide a bump-feed operating mode for the trimmer head. The spool also includes a separate, second pair of apertures configured to receive a single fixed-line trimmer line to provide a fixed-line operating mode for the trimmer head. The trimmer head is switchable between the fixed-line operating mode and the bump-feed operating mode without the need to disassemble the trimmer head.

A cartridge for a trimmer head and a trimmer. The trimmer head may include a housing assembly with a top member drivingly engaging a drive shaft of a trimmer. The cartridge may include a cartridge housing operable to support a line; and a brake assembly operable in a braking condition to selectively apply a force to the line to prevent line from being dispensed. The braking assembly may be operable between the braking condition and a release condition in an auto-feed mode, in cooperation with a flyweight, and in a bump-feed mode, when a bump member engages a surface.

A battery operated handheld power tool, the power tool (1) comprising a working tool assembly (20), comprising a working tool of the power tool and an electric motor, arranged to drive the working tool, a handle assembly (10), comprising a body portion (11) to which a battery pack (13) may be detachably connected, which battery pack (13) is arranged to provide electric power to the electric motor, a control unit (15), provided in the body portion (16) so as to control a flow of electric current from the battery pack (13) to the motor. The battery operated handheld power tool is characterized in that the body portion (11) comprises a fan (14), arranged to generate a flow of air passing by the control unit (15) during operation of the power tool (1).
