A power tool system that includes a power tool having a receptacle for receiving a battery pack, the receptacle including a mechanical interface for mating with a battery pack, a first battery pack having a battery pack housing, the first battery pack housing including a mechanical interface for mating with the power tool, the first battery pack housing having a first width dimension in a direction generally perpendicular to a direction in which the first battery pack mates with the power tool and a second battery pack having a battery pack housing, the second battery pack housing including a mechanical interface for mating with the power tool, the second battery pack housing having a second width dimension in a direction generally perpendicular to a direction in which the second battery pack mates with the power tool, wherein the second width dimension being at least about 1.5 times the first width dimension.

Power tool system

The invention is directed to an outdoor device, preferably a string trimmer, having a hinged pole for folding the string trimmer. The hinge has an easy to use lock that allows for repeated folding of the trimmer for easy transport and storage. The string trimmer has a battery at a rear end of the pole near the handle, and a motor at a front end on the cutting head. An electrical cable is run from the battery to the motor to provide power to the motor. The hinge provides a protective sheath around the cable to protect it from damage when the string trimmer is folded and the cable might otherwise be exposed. Additionally, the string trimmer includes a guard around the cutting head that contacts a battery housing to secure the string trimmer in a folded position.

The present invention is directed to a blowervac device having a grill that requires to distinct steps in securing the grill over a fan to activate a safety switch allowing power to the motor. The grill has an outer ring and a rotatable inner cover. The first step is simply to secure the grill over the fan. The second step requires the cover to be rotated, which activates an actuator for the safety switch, allowing power to be delivered to the motor and operation of the device. This two-step process reduces the likelihood if inadvertent operation of the device and reduces the chances of injury.

The battery housing assembly, connected to a support shaft assembly of a string trimmer, includes a base housing member defining a chamber configured to receive a battery therein. The base housing member includes a frontal member configured to engage a front of the battery, a top member extending from the frontal member, configured to engage the top portion of the battery, and a bottom member, configured to engage a bottom portion of the battery. A first side member is configured to be removably connected to a first side of the base housing member; and a second side member configured to be removably connected to a second side of the base housing member.

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.
