  • Ergonomic lateral manual sweeping device
    Patent number: 11731257
    Abstract: An ergonomic lateral sweeping device is described. In an embodiment, the device has a sweeping head such as a broom or rake head, and an elongated pole attached to the head. A paddle is rotatably attached to the elongated pole opposite the head, the paddle being wider than the elongated pole. The paddle has a front surface and a rear surface that extend horizontally and vertically so as to provide an area of contact between an arm and a torso. A handle is attached to the pole between the paddle and the sweeping head for rotation about a single axis with respect to the paddle. The handle has a hand grip to receive a rotational force to control a rotational position of the sweeping head with respect to the paddle, wherein the handle and the sweeping head rotate together with respect to the paddle about the single axis.
