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 attached to the elongated pole opposite the head, the paddle being wider than the elongated pole. Some embodiments also include a horizontal handle attached to the elongated pole and extending perpendicular to the elongated pole. ## Claims ### Claim 1 A sweeping device comprising a sweeping head; an elongated pole attached to the head; a paddle attached to an end of the elongated pole opposite the sweeping head, the paddle being wider than the elongated pole, the paddle having a front surface and a rear surface that extend horizontally and vertically with respect to the pole on respective opposite sides of the pole, wherein the front and rear surfaces are curved with a concave shape from the center of the front and rear surfaces to the edges of the front and rear surfaces so as to provide an area of contact between an arm and a torso; a handle attached to the pole between the paddle and the sweeping head, the handle having a hand grip in a form of a structure extending in two directions from opposite sides of an axis of elongation of the pole, and configured to rotate the sweeping head about only a single axis with respect to the paddle; and a pole connector at the end of the pole opposite the sweeping head including a cylinder in a bottom vertical hole of the paddle centered in the paddle and attached to the elongated pole and configured for rotation of the paddle with respect to the handle about the single axis. ### Claim 2 (depends on 1) The device of claim 1, wherein the pole connector allows the paddle to rotate freely about the vertical axis of the pole. ### Claim 3 (depends on 1) The device of claim 1, wherein the pole connector is a press fit connector. ### Claim 4 (depends on 1) The device of claim 1, wherein the bottom vertical hole has a diameter that is larger in an upper portion than in a bottom portion to retain the pole connector in the upper portion. ### Claim 5 (depends on 4) The device of claim 4, wherein the pole connector includes vertical tabs that press outward as a spring within the upper portion to secure the pole connector in the bottom vertical hole. ### Claim 6 (depends on 1) The device of claim 1, wherein the distance between the front and rear surfaces of the paddle is smaller at the center of the front and rear surfaces and is larger at the edges of the front and rear surfaces. ### Claim 7 (depends on 1) The device of claim 1, wherein the front and rear surfaces form a wedge shape with the narrow part of the wedge at the top of the paddle opposite the sweeping head where the front and rear surfaces are closer together. ### Claim 8 (depends on 1) The device of claim 1, wherein the handle extends equally in opposing directions and perpendicular to the axis of elongation of the pole from both sides of the of the axis of elongation of the elongated pole. ### Claim 9 (depends on 8) The device of claim 8, wherein the elongated pole has an upper section attached to the paddle and a lower section attached to the sweeping head and wherein the handle further comprises an upper bar attached to the upper pole section and a lower bar attached to the lower pole section and a hand grip between the upper and the lower bars. ### Claim 10 (depends on 9) The device of claim 9, wherein the handle has a first vertical support fastened to the upper bar and the lower bar and to one side of the hand grip and a second vertical support fastened to the upper bar and the lower bar and to an opposite side of the hand grip. ### Claim 11 (depends on 1) The device of claim 1, wherein the elongated pole has an upper section attached to the paddle and to the handle and a lower section attached to the sweeping head and to the handle and wherein the upper section telescopes to different lengths. ### Claim 12 (depends on 11) The device of claim 11, wherein the upper section comprises two concentric tubes that slide with respect to each other and a fixing device to hold the two concentric tubes in different relative positions. ### Claim 13 (depends on 12) The device of claim 12, wherein the fixing device is a lever action quick clamp attached to one of the tubes to clamp to the other one of the tubes. ### Claim 14 (depends on 1) The device of claim 1, wherein the pole connector is configured for rotation of the paddle during a sweep. ### Claim 15 A sweeping device comprising a sweeping head; an elongated pole attached to the head; a paddle attached to an end of the elongated pole opposite the head, the paddle being wider than the elongated pole, the paddle having a front surface and a rear surface that extend horizontally and vertically with respect to the pole on respective opposite sides of the pole, wherein the front and rear surfaces are curved with a concave shape from the center of the front and rear surfaces to the edges of the front and rear surfaces so as to provide an area of contact between an arm and a torso; a handle attached to the pole between the paddle and the sweeping head, the handle having a hand grip in the form of a structure extending in two directions from opposite sides of an axis of elongation of the pole, and configured to rotate the sweeping head about only a single axis with respect to the paddle; and a connector to attach the paddle to the elongated pole and configured for rotation of the paddle with respect to the handle about the single axis, wherein the connector allows rotation only about the single axis and not another axis. ### Claim 16 (depends on 15) The device of claim 15, wherein the single axis is the axis of elongation of the elongated pole. ### Claim 17 (depends on 15) The device of claim 15, wherein the handle extends across the elongated pole axis of elongation extending in two opposite directions from the elongated pole axis of elongation, the handle being fixed with respect to rotation about the elongated pole axis of elongation and configured to rotate the sweeping head when the handle is rotated. ### Claim 18 (depends on 15) The device of claim 15, wherein the paddle is a fulcrum of a class 3 lever and the sweeping head is a load. ### Claim 19 A sweeping device comprising: means attached to an elongated pole for securing an end of the elongated pole between a torso and an arm of a user, the means for securing extending horizontally and vertically to rest against the torso, the means for securing having front and rear surfaces that are curved with a concave shape from the center of the front and rear surfaces to the edges of the front and rear surfaces so as to provide an area of contact between the torso and the arm; means attached to the elongated pole for sweeping an object along the ground; and means attached to the elongated pole between the means for securing and the means for sweeping for receiving a gripping hand of the arm horizontally with respect to a vertical elongated pole on respective opposite sides of an axis of elongation of the pole and for moving the means for sweeping rotationally about a single axis of the elongated pole in response to a force from the gripping hand; and means between the means for securing and the means for receiving for rotating the means for receiving with respect to the means for securing only about the single axis and not another axis. ### Claim 20 (depends on 19) The device of claim 19, wherein the means for rotating is configured for rotation during a sweep.
