Abstract: A glider assembly for a handheld trimmer includes a glider shaft coupleable at one end with a rotating head of the handheld trimmer, and a glider plate connected to an opposite end of the glider shaft. The glider plate is part-spherical or saucer shaped and includes a concave side and a convex side. A bearing acts between the glider plate and the glider shaft. The assembly enables an operator to rest the weight of the trimmer on the ground during use while controlling a cutting height.

Abstract: An improved ball valve for use between dual fuel tanks having a non-circular outlet aperture leading to the fuel line and engine that can allow fuel to pass therethrough even when the ball contained within the valve rests in the opening of the outlet aperture.

Abstract: A reversible line blade for a rotating trimmer includes a loading section configured to be securable for rotation with a head of the rotating trimmer, a living hinge extending from the loading section, and a transition section extending from the living hinge and having a first cross-sectional shape with matching leading edge and trailing edge geometries. A cutting segment extends from the transition section and has a second cross-sectional shape that is different from the first cross-sectional shape. With matching lead edge and trailing edge geometries, the same line blade is functional for both clockwise trimmers and counter-clockwise trimmers.

Abstract: A golf putting aide locatable between a golf ball and a golf hole for use by a golfer putting the ball toward the hole to train the golfer to putt. The aide includes a frame supported by a support, the frame having a gap located at a lower portion of the frame and oriented so that during use of the aide when the ball is putted through the frame toward the hole the ball will pass through or below the slot on its path to the hole.

Abstract: A trimmer can be converted from an existing cutting medium to an alternative tool without requiring removal of the trimmer head. A common upper receiver head, as sold by an original equipment trimmer manufacturer, incorporates design provisions to snugly allow an easy/comfortable fit for a series of uniquely adaptable and convertible cap attachments such as, monofilament systems, unique molded or shaped flexible line blades with optional cutting swath diameters, as well as other helpful devices that perform different functions beyond just cutting grass.

Abstract: A sports aide for training a player to throw or kick a ball, comprising a spinning ring positionable proximal to the player and sized for passage of a ball therethrough, wherein during use of the aide the player will throw or kick the ball and attempt to have the thrown or kicked ball pass through the spinning ring.

Abstract: A basketball shooting aide locatable between a player shooting a basketball and a basketball goal to help the player to recognize an opportune moment to take a shot, to develop quickness in taking the shot at the moment, and to develop shooting accuracy. The aide includes a frame supported by a support, the frame having a gap located at an upper portion of the frame and oriented so that during use of the aide when the basketball is shot through the frame toward the goal the basketball will pass through the slot on its path to the goal.

Abstract: A line blade for a rotating trimmer includes a loading section securable for rotation on a cutting plane with a head of the rotating trimmer. A living hinge extends from the loading section. A transition section extends from the living hinge and has a first cross-sectional shape. The first cross-sectional shape is configured and oriented to reduce drag. A cutting segment extending from the transition section has a second cross-sectional shape that is different from the first cross-sectional shape of the transition section, where the second cross-sectional shape is configured and oriented for cutting vegetation. The multi-zone line blade improves cutting at lower speeds, thereby requiring less power.

Abstract: A walk-behind mower/trimmer includes one or more cutting heads secured to a deck supporting frame and supported on a glider disk. A rear support and handle assembly facilitate operator use and control of the mower/trimmer. The heads may be powered using a gas motor, an electric motor, or a hybrid.
