Gardening tool, particularly a grass trimmer
A gardening tool such as a grass trimmer is provided with a tool head, a motor for driving the tool head, a front housing for accommodating the motor, a trigger switch for activating the motor, a trigger operable to control the trigger switch, a battery pack for providing electric energy to the motor, a circuit board for electrically connecting the motor to the battery pack, and a rear housing for accommodating the circuit board. The rear housing forms a housing chamber for accommodating the trigger switch, the circuit board, and wires between the circuit board and the trigger switch.
HARVESTER WITH HEADER LIFT ASSEMBLY
The disclosure relates to header for a harvester including: a header frame; one or more harvesting elements carried by the header frame; a lift arm coupled to the header frame and configured to displace the header frame vertically relative to the ground; and a lift assembly displaceably coupling the header frame to the lift arm, the lift assembly being configured to displace the header frame vertically further than and/or independently of the lift arm.
Technique to improve waterproofness and dust resistance for circuit board in job-site gear
A job-site gear in one aspect of the present disclosure includes a circuit board, at least one electronic component, and a resin member. A first surface of the circuit board includes a first area, a second area, and a third area. The third area is located in a boundary between the first area and the second area. A second surface of the circuit board includes a fourth area, a fifth area, and a sixth area located behind the first area, the second area, and the third area, respectively. The third area and the sixth area include at least one slit penetrating through the circuit board. The resin member is integrally molded so as to (i) penetrate through the at least one slit and (ii) cover the first area, the fourth area, and a part of the at least one electronic component on the first area.
HANDHELD TOOL
A handheld tool includes a power assembly rotatably connected to a control assembly that is, in turn, rotatably connected to one end of a boom that has a tool assembly operatively attached to an opposing end thereof. The power assembly includes a power source, wherein the power source provides power to the tool assembly by way of the boom. The control assembly includes an actuating mechanism for selectively controlling the operation of the tool assembly. The tool assembly is both movable and operable by a single-handed operation. The tool assembly is ambidextrously controllable.
LOCK OFF ASSEMBLIES FOR TRIMMERS
Lock off assemblies for trimmers are provided. A trimmer includes a working head; a handle assembly connected to the working head by a connecting member; a trigger connected to the handle assembly and movable between an off position and an on position, wherein the trigger being in the on position causes actuation of the working head; and a lock off assembly. The lock off assembly includes a switch connected to the handle assembly and movable between a safe position and an operate position; and a pivotable extension pivotably connected to the switch, wherein the pivotable extension contacts and blocks the trigger when the switch is in the safe position and the trigger is moved from the off position towards the on position, and wherein the trigger is free to move between the off position and the on position when the switch is in the operate position.
ENGINE KILL SWITCH AND CONTROL ASSEMBLY
A kill switch assembly for an internal combustion engine may include a housing, a first terminal carried by the housing and connected to a ground wire, a second terminal carried by the housing and connected to an engine microcontroller communication wire, and a kill switch. The kill switch may be carried by the housing, electrically connected to the first and second terminals, and manually operable by an operator to change the state of the electric switch to provide an engine stop signal to the engine microcontroller. The assembly may also include an electronic circuit carried by the housing, connected to the first and second terminals, and through the wires communicating with the engine microcontroller.
Vegetation cutter
A vegetation cutter comprises: a frame rod having a longitudinal axis and a front end; a rotary cutter mounted on the front end of the frame rod; a drive motor for driving the rotary cutter; a grip disposed around the frame rod and having an external surface to be held by a user; a power switch trigger arranged on the grip for energizing the drive motor; and a safety lock mechanism for rendering the power switch trigger inoperative when the safety lock mechanism is in a lock position and for rendering the power switch trigger operative when the safety lock mechanism is in a release position. The safety lock mechanism includes a manipulating knob for selectively setting the safety lock mechanism in the lock position and in the release position. The manipulating knob is disposed on the grip at a position circumferentially opposite to the power switch trigger and is turnable around an axis which is parallel to the longitudinal axis of the frame rod to selectively bring the safety lock mechanism to the lock position and the release position.
ARRANGEMENT OF HOUSING AND GUIDE TUBE AND HANDHELD WORK APPARATUS HAVING SAID ARRANGEMENT
An arrangement of a housing and a guide tube is provided wherein one end of the guide tube is held in the housing. The position of the guide tube is adjustable relative to the housing in the direction of the longitudinal center axis of the guide tube. A rotation stop stops swiveling of the guide tube relative to the housing and includes a guide part. The guide part is mounted in one of the guide tube and housing. A longitudinal wall runs in the direction of the axis on the other one of the guide tube and housing. The longitudinal wall interacts with the guide part during swiveling of the guide tube about its axis. The guide part is tiltable relative to the guide tube about a tilt axis. The tilt axis runs along the guide tube and at a distance (a, b) from the axis of the guide tube.
Hand-guided garden, forestry and/or construction working apparatus and method for a hand-guided garden, forestry and/or construction working apparatus
A hand-guided garden, forestry and/or construction working apparatus has an inactive state, an active state and a variable setting, as well as an apparatus operator control element which can be activated by a user. In the inactive state, the garden, forestry and/or construction working apparatus is designed to be transferred into the active state triggered by activation of the apparatus operator control element, and in the active state the garden, forestry and/or construction working apparatus is designed to change the setting and not to be transferred into the inactive state triggered by activation of the apparatus operator control element.
