摘要： An adjustable mowing and trimming apparatus is presented having a wheel adjust mechanism and trimming assembly. The apparatus includes a housing to which at least two wheels are rotatably mounted at opposite sides of the wheel adjust mechanism. The wheel adjust mechanism includes a pair of wheel brackets having a C-shaped configuration, each of which pivotally attaches to the housing and is provided with an outwardly extending axle for supporting a wheel. A tie rod attaches at respective opposite ends to the wheel brackets. A slotted bracket is attached to the tie rod and movable in response to a movable arm to reorient the wheels on either side of the housing. The trimming assembly is mounted at a front portion of the housing and includes a spindle assembly rotatably attached to a shaft, which is fixedly attached to the housing.

摘要： An adjustable mowing and trimming apparatus is presented which employs a unique wheel adjust mechanism and trimming assembly. The apparatus includes a frame to which at least two wheels are rotatably mounted at opposite sides of an adjustable linkage which is loosely coupled to the frame through a moveable pivot assembly. A mechanism is provided for manually adjusting the moveable pivot assembly to actuate the adjustable linkage and thereby reorient the wheels on either side of the frame. The trimming assembly is mounted at a front portion of the frame and includes a spindle head fixedly mounted to a spindle depending from the frame so as to rotate with the spindle. The spindle head substantially covers the spindle and is sized such that a distal end thereof rests proximate to ground when the trimming apparatus is operational. A trimmer head is adjustably clamped about the spindle head so as to rotate therewith. The trimmer head has a plane of cutting substantially perpendicular to the axis of rotation of the spindle and the cutting plane is infinitely adjustable within a range defined by a length of the spindle head.

摘要： A modular step system for in-ground swimming comprising a bottom central hub, a brace assembly, a top central hub, a tread support assembly, a step form and a liner. The components of the modular step system interlock and snap together without fasteners. Also, the components of the modular step system are obtained by molding plastic material or curing of a curable material. The modular step system is installed on a level concrete floor of a swimming pool and designed to be rigidly fixed from behind to adjacent pool walls. The modular step system is adaptable to a pool having a vinyl liner, structurally sound regardless of size, easy to assemble, consistent in size, and cost-effective.
