The centrifugal clutch mechanism also includes a plurality of centrifugal weights disposed in the internal cavity and an inward biasing element engaged with the centrifugal weights. The inward biasing element biases the centrifugal weights towards a disengaged position in which the centrifugal weights do not interface with drive surface, and upon application of a sufficient centrifugal force, the centrifugal weights are configured to transition to an engaged position in which the centrifugal weights interface with the drive surface.

Abstract: A lubrication system for a chainsaw, the lubrication system including a reservoir housing a lubricant, a fluid conduit extending between the reservoir and a location adjacent to a chain of the chainsaw, a pump configured to move lubricant from the reservoir to the location adjacent to the chain, and a valve disposed along the fluid conduit. The valve has a lubricant inlet that receives lubricant from the reservoir, an air inlet, and an outlet that provides lubricant to the location adjacent to the chain. The valve is movable between an open position whereby lubricant passes from the lubricant inlet to the outlet and a closed position whereby the outlet is in fluid communication with the air inlet. The valve moves between the open and closed positions in response to a user input.

Abstract: A blower vacuum, the blower vacuum including a nozzle forming a first opening, a fan housing in fluid communication with the nozzle, an inlet exhaust housing rotatably coupled to the fan housing, and a debris housing. The fan housing forms a second opening. A fan assembly is positioned at the fan housing. The inlet exhaust housing includes an inlet portion and an exhaust portion. The inlet exhaust housing is rotatable to a first position forming a blower operation and a second position forming a vacuum operation. The debris housing is coupled to the exhaust portion of the inlet exhaust housing.

Abstract: Systems and methods which provide motive forces with respect to various apparatuses using self-engaging/disengaging transmission configurations are described. An autonomous-state transmission may comprise a transmission unit configured to autonomously engage and disengage transmission of power from a driving input member to a driven output member without utilization of external gearing or additional mechanical feedback. Embodiments of an autonomous-state transmission may utilize various roller-ramp clutch configurations in communication with override control for disengaging the roller-ramp clutch. The override control may implement various configurations of a skidding mechanism for facilitating engaging and/or disengaging the roller-ramp clutch. According to some examples, motion of the driving input member and/or driven output member is utilized for override force detection and providing override control with respect to the autonomous-state transmission.

Abstract: A stackable storage system includes a first container, a second container, and a latch moveable between a first position and a second position. The first container includes a projection extending away from the first container along a stacking direction. An edge portion extends from the projection along a plane substantially perpendicular to the stacking direction. The second container includes a recess. The recess receives the projection when the first container and the second container are stacked relative to one another in the stacking direction. The latch overlaps the edge portion with respect to the stacking direction while in the first position to secure the first container and the second container. The latch and edge portion are positioned in a non-overlapping manner relative to one another while the latch is in the second position to permit separation of the first container from the second container.

Abstract: A storage system includes a panel secured to a support surface and a storage container removably supported on the panel. The panel includes a plurality of cleats. The storage container includes a first container portion, a second container portion, and a support feature engageable with the cleats. The second container portion and the first container portion are pivotably movable between a closed position and an open position. The support feature includes a first partial mounting portion and a second partial mounting portion. The second partial mounting portion is movable between a stowed position and an extended position. The first partial mounting portion and the second partial mounting portion cooperate to provide a mounting interface to engage the cleats while the second partial mounting portion is in the extended position.

Abstract: A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.

Abstract: A blower, comprises a blower body, accommodating therein a fan and an electric motor driving the fan to rotate. A rotation shaft of the fan defines a longitudinal axis. A blow pipe is removably attached to the blower body. A tapered member is provided between the electric motor and an air inlet of the blower body, the tapered member gradually narrowing toward the air inlet.

Abstract: An electric handcart, comprising: a main body (1), a power supply device (9) mounted on the main body (1), a power device, and a control device. The power supply device (9) and the control device are separately connected to the power device.

Abstract: A lighting mosquito killer lamp which includes a main body and a base joined with the main body. The main body includes a housing, a lampshade arranged in the housing, and a high-voltage mesh wire arranged on the lampshade. The base receives power. The lighting mosquito killer lamp further includes a lighting lamp and an ultraviolet lamp. The lighting lamp is different from the ultraviolet lamp, and the lighting lamp and the ultraviolet lamp are controlled independently of each other. The lighting mosquito killer lamp further includes a cleaning brush having bristles that clean away mosquitos attached to the high-voltage mesh wire as the cleaning brush moves along a guide rod of the housing. The cleaning brush includes a brush handle that protrudes from the housing for operation by a user.
