  • Patent number: 7690177
    Abstract: A string trimmer mechanism intended for mounting on the front end of a mowing tractor. The mechanism includes a mounting bracket for attachment to the front end of the tractor; an extension power cylinder pivotally mounted on the bracket and extending laterally of the tractor; a string trimmer carried on the free end of the power cylinder and including a hydraulic motor driving a trimmer dish; and a lift power cylinder pivotally mounted on the bracket and driving a lever pivotally mounted on the bracket and carrying a roller positioned under the extension power cylinder. The string trimmer is moved selectively laterally inwardly and outwardly utilizing the extension power cylinder and is moved selectively upwardly and downwardly utilizing the lift power cylinder. The extension power cylinder, lift power cylinder, and hydraulic trimmer motor are selectively supplied with pressurized hydraulic fluid from a pressurized hydraulic fluid source onboard the tractor.

  • Patent number: 6363577
    Abstract: A motor vehicle door handle assembly including a housing structure adapted to be mounted on a vehicle door and a handle pivotally mounted at one end thereof on the housing structure at an arcuate bearing interface. The bearing interface comprises an inner bearing interface comprising coacting first and second arcuate surfaces and an outer bearing interface spaced radially outwardly from the inner bearing interface and comprising coacting third and fourth arcuate surfaces. All of the arcuate surfaces are centered on the handle pivot axis. The first arcuate surface comprises a radially outwardly facing handle surface; the second arcuate surface comprises a radially inwardly facing housing structure surface; the third arcuate surface comprises a radially inwardly facing handle surface; and the fourth arcuate surface comprises a radially outwardly facing housing structure surface.

  • Patent number: 6099052
    Abstract: A door handle assembly for a motor vehicle which acts to preclude inadvertent unlatching of the door in response to a side impact. The door handle assembly includes a bezel housing and a handle member including a handle portion positioned in a bowl portion of the bezel housing and a crank arm portion extending outwardly and upwardly through a slot in the bowl portion for connection to a pivot shaft. A sliding, spring biased weight is mounted on the bowl portion of the bezel proximate the location where the crank arm of the handle passes through the slot in the bowl portion. The weight moves slideably into coaction with a detent structure on the crank arm of the handle member in response to a side impact to preclude pivotal movement of the handle member in an unlatching direction.
