An example collapsible blower extension for a leaf blower is provided. The collapsible blower extension may include an elongate body forming an internal airflow passageway. The elongate body may be formed of a pliable material causing the internal airflow passageway to be collapsible. The collapsible blower extension may also include an input opening at a proximal end of the elongate body configured to be disposed proximate a leaf blower working assembly airflow outlet and an output opening at a distal end of the elongate body.

A mechanical breather system for a four-stroke engine includes a rotating member. The rotating member can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member and an inner region of the rotating member. A breather housing having an air receiving chamber formed therein is fluidly coupled to the at least one inlet channel of the rotating member. A passage can be formed through a wall of the breather housing is in fluid communication with the air receiving chamber and an exterior of the breather housing.

A hand carried power tool () is presented which includes a vibration-producing power unit () interconnected with an elongate handle (). The handle () has a base end () coupled to the power unit () and an opposite free end () configured for manual gripping. Additionally a vibration damping member (), which permits vibration-induced movement between the base end () of the handle () and the power unit (), interstitially located between the base end () of the handle () and the power unit (). Furthermore, a resilient biasing member () is coupled between the elongate handle () and the power unit (). The biasing member () connects to the handle () at a location distant from the base end () of the handle () and the biasing member () is configured to dampen vibration-induced relative movement between the base end () of the handle () and the power unit ().

A powered blower/vacuum unit includes a base portion having a housing and a power air-moving device within the base portion. A tube is provided that is formed by a first manufacturing operation, such as a blow molding process. The tube extends a relatively large distance away from the housing and air flows through the tube along a relatively large distance. A coupler is also included for coupling the tube to the housing. The coupler is separately formed by a second, different manufacturing operation, such as an injection molding process. The coupler includes a plurality of one-way snap-in features configured to engage a plurality of receiver features located on the tube to non-removably attach the coupler to the tube. The housing can also include at least one male component and the coupler can include at least one complementary female component for securing the coupler to the housing.

Tube coupler

A power tool includes vibration isolation material positioned between an engine shroud and a drive shaft housing. The vibration isolation material isolates the drive shaft housing from engine vibration for radial, axial, and torsional movement without utilizing intermediate components.
