  • Patent number: 11980955
    Abstract: Circular saws with lock assemblies are disclosed herein. The circular saws include a motor including a motor shaft configured to rotate about a shaft rotational axis. The circular saws also include an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws further include a switch configured to selectively apply an electric current to the motor and a switch lever configured to be selectively actuated, by a user of the circular saw and via an actuation force, to actuate the switch and direct the switch to apply the electric current to the motor. The lock assemblies include a switch lock, which defines a switch-locked configuration, in which the switch lock resists actuation of the switch lever by the user, and a switch-unlocked configuration, in which the switch lever is free to be actuated by the user.

  • Publication number: 20240131744
    Abstract: A sawing apparatus can have a drive shaft that is rotatable about a central axis for rotationally driving a saw blade. The apparatus includes an electrical rotary feedthrough for the electrically conductive connection of the drive shaft to a connection assembly. The electrical rotary feedthrough includes a first component having a contact section that tapers in the direction of a second component and the shell surface of said contact section forms a first contact surface. The second component has a receiving channel that extends along the central axis and the side surface of the receiving channel forms a second contact surface. The first contact surface lies against the second contact surface in sections. The receiving channel and the tapering contact section has a clearance for ruling out a purely axial abutment of the components. In addition, an electrical rotary feedthrough for a sawing apparatus, is described.

  • Publication number: 20240131605
    Abstract: Circular saws having a blade that moves relative to a stationary base structure during operative use of the circular saws to cut a workpiece and methods of detecting a kickback condition of such circular saws. The circular saws include a base structure, a user-actuated assembly, an attachment structure, and a controller. The attachment structure is configured to permit constrained relative motion between the base structure and the user-actuated assembly in a motion direction and during operative use of the circular saw to cut the workpiece. A motion sensor is configured to generate a motion signal indicative of motion of the user-actuated assembly along the motion direction. The controller is programmed to initiate a kickback response of the circular saw responsive to the motion signal being indicative of a kickback condition of the circular saw.

  • Publication number: 20240123650
    Abstract: Handheld power tools with kickback detection and methods of detecting a kickback condition of a handheld power tool are disclosed herein. The methods include moving an implement of the handheld power tool within an implement motion plane and in detecting motion of the handheld power tool. The methods also include determining that the kickback condition exists based, at least in part, on the motion of the handheld power tool. In some embodiments, the handheld power tool is a circular saw that includes a user-actuated assembly. The user-actuated assembly includes a motion sensor, a controller, and a motor. The circular saw also includes a workpiece support and a pivot. The motion sensor is configured to detect acceleration along an acceleration detection axis that extends a threshold pivot axis-acceleration axis distance of at most 4 cm from a pivot axis of the pivot.

  • Publication number: 20240091977
    Abstract: Bevel saws and methods of adjusting a fence of a bevel saw are disclosed herein. The bevel saws include a workpiece support that defines a workpiece support surface. The bevel saws also include a user-actuated assembly and an assembly attachment structure that operatively attaches the user-actuated assembly to the workpiece support. The assembly attachment structure includes a blade bevel angle adjustment mechanism configured to adjust a blade bevel angle of the bevel saw blade. The bevel saws also include a fence that defines a fence surface that extends away from the workpiece support surface. The fence includes a first fence region and a second fence region. The first fence region and the second fence region define a blade-receiving gap therebetween, and the fence further includes a gap adjustment mechanism configured to automatically adjust the blade-receiving gap based, at least in part, on the blade bevel angle.
