Abstract: A pull start assist device may include a frame with a base and a longitudinal member. The longitudinal member may include a first pivot axis and a second pivot axis displaced from the first pivot axis. The device may also include a pedal arm with a pedal on a first end and a second end pivotally coupled to the first pivot axis of the longitudinal member. A swing arm may be provided with a handle receiver on a first end and a second end pivotally coupled to the second pivot axis of the longitudinal member. A connection link maybe used to connect the swing arm and the pedal arm, whereby a pull start handle of a powered tool may be supported by the handle receiver and the pedal displaced by the foot of a user, actuating the swing arm and starting the powered tool.

Abstract: An adjustable duct start collar may include a base with a flange on a first end of the base and a plurality of tabs on a second end of the base. The base may be constructed of a material of substantially uniform thickness and include at least two slots in the base. The first of the slots may be positioned substantially parallel to a second of the at least two slots. Each of the slots of the at least two slots being able to independently receive the flange, whereby when the base is curved into a cylindrical shape with the flange positioned in the first of at least two slots, the curved base will form a cylindrical shape with a first diameter and when the flange is positioned in the second of the at least two slots, the curved base will form a cylindrical shape with a second diameter.

Abstract: The disclosed invention is a method and device for removing dirt and other debris from an open trench. The invention includes a tool with an elongated handle and a blade attached thereto. The blade is cantilevered from the support to allow positioning of dirt and other debris thereon. The combination creates an elongated shovel with a substantially flat bottom edge, so as to conform to the bottom of the trench. The handle and blade make a slightly acute angle one to another, with the center of gravity of the combination being below the handle when the handle is in a substantially vertical position and the placement of debris on the blade making little if any movement of that center of gravity. This method allows the user to stand directly over an open trench and remove soil with the tool with minimal displacement of the weight of the combination from the body of the user. This minimal displacement results in minimizing lower back stress while performing the task. Refilling of the trench is also assisted by allowing the user to be in an upright position with the blade of the tool flat on the ground and push or pull the soil back into the trench, without lifting the soil or putting the user in an awkward position.
Abstract translation: 所公开的发明是用于从打开的沟槽去除灰尘和其它碎屑的方法和装置。 本发明包括具有细长手柄和连接到其上的刀片的工具。 叶片从支撑件悬臂，以便将污垢和其他碎屑定位在其上。 该组合产生具有基本上平坦的底部边缘的细长铲，以便符合沟槽的底部。 当把手处于基本上垂直的位置时，把手和刀片彼此形成一个稍微锐利的角度，当把手处于基本上垂直的位置时，组合的重心位于手柄下方，并且碎屑放置在刀片上几乎没有该中心的运动 的重力。 这种方法允许使用者直接站在开放的沟槽上并用工具去除土壤，同时使组合的重量从使用者身体的最小位移移除。 这种最小位移导致在执行任务时最小化后背应力。 通过允许使用者在工具的刀片平放在地面上并将土壤推回或拉回到沟槽中而不用提起土壤或使使用者处于尴尬的位置，也可以帮助使用者处于直立位置 。
