Abstract: A rotary tool includes a housing, a drive shaft positioned within the housing, and a bit holder. The bit holder is positioned adjacent a distal end of the housing and is driven by rotation of the drive shaft. The rotary tool also includes a wrench assembly for adjusting the bit holder and a light source configured to emit light in a direction toward the bit holder. The wrench assembly is positioned adjacent the bit holder and is movable between a first position and a second position. The wrench assembly is coupled to the housing and disengaged from the bit holder assembly in the first position and is engaged with the bit holder assembly in the second position.

Abstract: A circular saw includes a base with an opening therethrough, a blade guard coupled to the base, and a saw blade at least partially positioned within the blade guard and extending through the opening of the base. The saw blade and the blade guard are pivotable relative to the base to adjust a bevel angle of the saw blade relative to the base. The circular saw also includes a housing supported by the blade guard, a motor positioned within the housing that is operable to rotate the saw blade, and a bevel angle guide coupled between the base and the blade guard. The bevel angle guide configured to indicate the bevel angle at which the saw blade is adjusted. The bevel angle guide is integrally formed with the base as a single piece.

Abstract: A handheld vacuum cleaner includes a housing, a motor, and a dirt cup. The housing defines a top, a bottom, a motor chamber, a dirty air inlet at a front of the housing, a handle at the rear of the housing, a clean air outlet, and an airflow path from the dirty air inlet to the clean air outlet. The handle has a grip portion. The housing further includes a continuous elongate structural member extending from the dirty air inlet into the grip portion of the handle. The motor is disposed in the motor chamber. The dirt cup is coupled to the elongate structural member. The dirt cup is in fluid communication with the dirty air inlet and the motor. The elongate structural member defines a portion of the airflow path extending from the dirty air inlet.

Abstract: A coupler includes a collar defining a member receiving passage. First and second lobes extend outwardly from the collar. The first lobe includes a lobe ramp surface, a cylindrical projection extending from the first lobe and radially surrounding the lobe ramp surface, and a gear extending from the cylindrical portion. A passage is defined in the first and second lobes and has a first axis. A lever arm is rotatable about the first axis. The lever arm includes a lever ramp surface. A pawl arm is movably connected to the lever arm. The pawl arm includes a portion biased into engagement with the gear teeth. A fastener extends through the passage and couples the lever arm to the first lobe so the lever ramp surface cams with the lobe ramp surface. Rotation of the lever arm in a first direction brings the first and second lobes toward each other.

Abstract: An air purifier includes a housing having an air inlet and an air outlet, a filter disposed adjacent the air inlet, a blower unit disposed within the housing to draw air through the air inlet and expel air through the air outlet, a battery receptacle configured to engage a battery for providing power to the motor, and a handle coupled to the housing to facilitate transportation of the air purifier. The blower unit includes a motor and an impeller driven by the motor to induce an air flow, and rotation of the impeller induces air flow at a rate between approximately 400 cubic feet per minute and approximately 800 cubic feet per minute.

Abstract: A battery pack including a housing having a first end, a second end, and a longitudinal axis that extends between the first end and the second end, electrical terminals positioned within the housing and configured to engage and electrically couple with electrical terminals of a power tool, and a latch mechanism including an actuator and a latch member that is spaced apart from the actuator. The actuator has a distal end that is positioned adjacent the first end of the housing, a proximal end that is spaced apart from the distal end, and an actuating surface that extends between the distal end and the proximal end. The actuating surface has a gradually decreasing slope between the distal end and the proximal end.
