Portable vacuum

A power tool is provided including a housing, a motor disposed within the housing, an on/off switch having a contact tip disposed within the housing for activating the motor, a paddle switch coupled to the housing via a pivot member and having a paddle trigger engageable by a user, a switch contact lever disposed in selectable engagement with the contact tip of the on/off switch to activate or deactivate the on/off switch, and a biasing member disposed between the switch contact lever and the paddle switch to absorb a travel distance of the paddle trigger with respect to the switch contact lever.

Paddle switch

A power tool is provided including a motor driving a shaft and a drive spindle. The drive spindle includes an outer spindle rotatably driven by the shaft and an inner spindle disposed within the outer spindle. The outer spindle includes an end portion defining an engagement surface for mounting a working accessory, and the inner spindle is axially moveable along a longitudinal axis of the outer spindle but rotationally fixed to the outer spindle. A spring member is arranged to apply a biasing force on the inner spindle in a first direction with respect to the outer spindle. Securing the working accessory on the drive spindle against the engagement surface of the outer spindle applies an axial force on the inner spindle in a second direction opposite the first direction with respect to the outer spindle.

Accessory clamp and spindle lock mechanism for power tool

A stop lever is provided for a power tool having a gear case and a guard member. The reversible stop lever is coupled to the gear case via a fastener. The stop lever includes a first arm and a second arm, and the fastener is removable to position the stop lever such that the first arm or the second arm of the stop lever engages the guard collar. The first arm includes a first surface and a second surface that are angled such that the guard collar can be rotated in a one direction without actuation of the second arm, but not in the opposite direction. The second arm of the stop lever includes surfaces that are angled to prevent rotation of the guard collar in either direction unless the second arm is actuated about the fastener.

Reversible lever for a guard assembly for a power tool

A power tool is provided with a housing and a tethering attachment assembly attached to the housing and adapted to facilitate connection of a lanyard to the power tool. The tethering attachment assembly includes a substantially U-shaped hook portion including a coil element comprising metallic material that substantially resiliently retains its state with application of force up to a limit, and is permanently plastically deformable upon application of force exceeding the limit, and two extended portions extending from ends of the coil element and attached to the housing.

Impact-absorbing tethering attachment

A tethering attachment assembly is provided for attachment to an apparatus to facilitate connection of a lanyard to the apparatus. The tethering attachment assembly includes a pair of posts and a coil element including metallic material that substantially resiliently retains its state with application of force up to a limit, and is permanently plastically deformable upon application of force exceeding the limit. The coil element has two ends attached to the elongated posts and adapted to form a substantially U-shaped hook when the elongated posts are attached to the apparatus. A sleeve is tubularly disposed around the coil element to substantially cover the coil element.

A guard lock for a powered apparatus having a neck extending from a gear case is provided. The guard lock includes a guard member having a body portion for at least partially surrounding a working member of the power tool and a collar connected to and extending from the body portion, where the collar includes multiple windows that are spaced from one another. The guard lock also includes a stop lever coupled to the gear case via a fastener about which the stop lever may pivot, the stop lever including an engagement portion and a distant arm portion, and a biasing member for biasing the engagement portion of the stop lever toward a window of the collar. When the engagement portion is positioned within a window, rotation of the collar is permitted in a first direction where the window engages a first surface of the engagement portion but is prevented in a second direction where the window engages a second surface of the engagement portion. A depression of the distal arm portion toward the collar pivots the engagement portion away from the window.

Guard lock

A power tool is provided including a having a field case portion and a gear case portion, a motor disposed in the field case portion of the housing, a fan rotatably connected to the motor, intake conduits disposed along the housing, and a particle separation assembly in fluid communication with the intake conduits. The particle separation assembly includes a baffle and a centrifugal chamber, where the baffle is operable to direct airflow from the intake conduits into the centrifugal chamber in a cyclonic path, and the centrifugal chamber includes a radial gap forming a particle dispersion port in the cyclonic path of the airflow to eject contamination from the airflow. Additionally or alternatively, the centrifugal chamber includes air-directing fins arranged angularly to direct contamination from the airflow towards the particle dispersion port.

Particle separation assembly for power tool

A hinge assembly for attaching a door member to a main structure is provided. The hinge assembly, in an embodiment, includes a first hinge member securely attached to one of the door member or the main structure; a second hinge member securely attached to the other of the door member or the main structure and rotatably engaging the first hinge member; and a cam/spring assembly configured to bias the door member into an open or a closed position with respect to the main structure.

Hinge assembly for an angle grinder dust shroud

The present invention is directed toward a shield assembly for a handheld tool device such as an angle grinder. The shield assembly is selectively repositionable with respect to the cutting tool. A lock mechanism secures the shield assembly in discrete rotational positions relative to the cutting tool. The shield assembly includes a guard member and a bumper member, and an alignment feature configured to align the relative positions of guard member and the bumper member, thereby positing the members in a predetermined relative orientation. With this configuration, the shield assembly is selectively repositionable via a 'hands-free' mechanism that permits a user to adjust the position of the shield assembly by simply contacting the shield assembly against a work surface.
