  • Publication number: 20250351943
    Abstract: According to examples, a backpack power equipment may include a power equipment, a base frame to be worn on a user's back, a connecting member connecting the power equipment to the base frame about an axis at a first height from a bottom of the base frame, a motor controller module mounted to the base frame, and a battery management module mounted to the base frame. The motor controller module and the battery management module are both positioned above the first height. By positioning the motor controller module and the battery management module above the first height, more of the weight may be at a higher position, which may enable a user to maintain a more upright posture during use, which may improve ergonomics of the backpack power equipment disclosed herein.

  • Publication number: 20220134593
    Abstract: The present invention is directed to a chain saw having a chain tension knob to adjust the tension of a chain. The knob is rotated to move the chain bar to increase or decrease the tension on the chain depending on the direction of rotation. The knob is positioned at a forward portion of the chainsaw housing, below the chain bar. The knob acts as a chain catcher so that in case of chain breakage or derailment, it blocks the chain from swinging rearward toward the user and reduces the likelihood of serious injury.
