Abstract: This grounds tool supporting handle mounts at an upper end portion of a support and an implement mounted at a use end of the support. Each such handle includes a ball joint largely retained in a ball socket closure for making multiple adjustments of the handle beside the powered grounds tool support longitudinal axis, while simultaneously making sufficient height adjustments to the implement in relation to the grounds surface. Optionally, this handle may be equipped with improved damping mechanisms and or tool adjusted when the powered grounds tool demands a stationary mode of operation.

Abstract: An aerobic mouthguard having a plurality of treads intermittent to one of a plurality of recesses forming an oral footprint and or an opposite oral footprint for larger oral shock diffusion and larger oral osmotic equilibrium. Each oral footprint may comprise a plurality of ducts and v-cuts that taper toward their posterior end for retaining larger oral fluids. The aerobic mouthguard can comprise a single rigid footprint for stress related contact sports or a double elastic footprint for stress-free dental therapy and treatment. A tab defining a lip footprint can be forwardly part of the aerobic mouthguard, and a tether or a drool cup having one or more drool pads can be forwardly part of the tab for larger oral osmotic equilibrium to prevent tooth loss.

Abstract: A handheld lawn tool including a first arm and a second arm, a third arm horizontally on the first arm and a forth arm pivotally on the second arm, an operator applying a functional grip on a first control grip over the third arm and on a second control grip along a first forward transport path in a horizontal cutting circle of a cutting tool, a reverse hand grasp on the second control grip for transposing the second grip into a third control grip with the boom arranged in a diagonal direction, the first functional hand grasp on the first control grip plus the second functional hand grasp on the third control grip with a vertical cutting circle of the cutting tool in a second transport path, the balancing point of the boom transposing between the transport path.

Abstract: A grounds tool with means for transposable grips with an upright input arm having a first grip and a trigger, an output arm having a line filament or bladed working end and a button or a dual button end couples the input arm, the button engages a mid-slot or the dual button engages mirrored slots forming a boom, a motor on the boom for driving the line filament and bladed tools, the output arm held within left and right mirrored isometry folds having a second grip to transpose a third and forth grip, the second control grip and the tools having to transpose congruently with the button folds, a front suspension complementary and supplementary to the operator shield radian walls that are about twice the boom tilt, a chamber having to duplicate, reciprocate or reverse the tools with uniform airflow and the fifth grip having to translate the motor.

Abstract: A yard tool or unit having the motor barrier bracket upright when the tool barrier bracket and the control barrier bracket are rotated. The tool barrier bracket having flared operator and tool nozzle shields, a front suspension, one or more line filament or bladed tools, uniform air intake open to a fan to discharge debris and hold lubricants in a chamber. The front suspension fixed or to dial into tool heights and balance the unit. The tool output combines for no more than 200 rpm variance of motor input. The control barrier bracket having to mount a handlebar near the unit fixed point with a neighboring tool control grip, power control grip and transmission. The neighboring control grip to rotate the line filament or bladed tool in the right or left single fold operating framework free of collapsing.

Abstract: A front suspension for a yard tool mounted on a bracket to a boom, the bracket having to support a drive shaft, a cutting disk, a shield and one or more front suspensions to dampen power transfer, the front suspension having a frame preferably connected to a wheel at a distal end and coupled to the bracket at a proximal end, the front suspension operated in parallel single orthogonal fold frameworks with height and width adjustments substantially below the yard tool center of mass, the front suspension having to support the yard tool in equilibrium in all operative and inoperative positions to save power, to guide the cutting disk with a longer and straighter cut, to dampen the cutting disk resistance adjacent to hard surfaces, and to fold away for the shield and cutting disk to perform soft yard grounds work.

Abstract: A yard tool harness tie-down with a band, the band generally connected above a yard tool equilibrium point, the band having a north brace, the band having a south brace, the band having an east brace, the band having a west brace, the north brace having to be connected to a harness, the south brace connected to a swivel button, the swivel button having to connect to a harness clip, the harness clip having to connect to a plurality of yard tools, the east brace connected to a fixed tie-down, the fixed tie-down connected to a outer union, the west brace connected to an adjustable tie-down, the adjustable tie-down connected to a outer union, the inner union having to couple with the outer union, and the inner and outer unions having to tie down the yard tool harness close to the harness clip.

Abstract: A yard tool having a motor connected to a string trimmer for light lawn grooming purposes or other auxiliary yard tool attachments, each yard tool attachment having a separate shaft and handle that attach to the motor by a rotation and translation locks, the translation lock further having a three-way bayonet lock for one or more shaft button stops to lock into, the yard tool attachments having a series of longitudinal, lateral and vertical working planes that can be orientated along identical transport routes, a power control handle having an aperture for an index finger to compress the button stops to release the motor from the yard tool attachments, the power control handle having ribs that are slightly compressed onto the shaft and tracks for the button locks to glide through, the rotation lock maintains the string trimmer and tool attachments in a fixed orthogonal isometry.
