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. The string trimmer mechanism converts between left hand operation, with the string trimmer positioned on the left side of the tractor, and right hand operation, with the string trimmer positioned on the right side of the tractor, simply by reversing the direction in which the extension power cylinder extends from the mounting bracket and by interchanging the pivotal mounting of the lift cylinder and the lever on the mounting bracket.

Tractor mounted string trimmer mechanism

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. Assembly of the handle assembly is facilitated by the provision of a separate pivot member which is positioned on a pin structure defined at one end of the handle and which coacts with the pin structure to define the inner bearing interface. The outer bearing interface is defined by a journal surface on the handle in radially outwardly spaced concentric relation to the pin structure and a convex outer surface of an arcuate trunnion structure of the housing.

Motor vehicle door handle assembly with maximized bearing interface

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.

Door handle assembly with inertial lock

An automotive door handle assembly adapted to be mounted in an aperture defined in the outer skin of a motor vehicle door by a flange structure. The assembly includes an escutcheon plate sized to fit in the door skin aperture and having a peripheral flange sized to fit against an outer face of the outer door skin in surrounding relation to the door skin aperture. The door handle is pivotally mounted on a front face of the escutcheon plate for door unlatching movement, and a locking member is slidably mounted on a rear face of the escutcheon plate. The locking member is maintained in a preliminary mounting position by latching engagement of a latch on the locking member with a latch on the rear face of the escutcheon plate and pivotal movement of the handle has the effect of releasing the latching engagement of the locking member with the escutcheon plate to allow the locking member to move under spring biasing to a locking position in which pins on the locking member engage an inner face of the door skin flange structure to pull the escutcheon plate flange against an outer face of the door skin flange structure. Mounting of the door handle assembly in the door therefore consists simply in passing the assembly through the door aperture and actuating the door handle.

Door handle assembly with self-actuated mounting

A method of attaching a vehicle door handle to the a vehicle door, and a door handle assembly to facilitate such attachment. The door skin includes a plurality of individual, spaced apertures. The door handle assembly includes a handle member, a base plate pivotally mounting the handle member and defining a planar surface, a plurality of lugs on the base plate each sized to pass through a respective aperture and each defining a web portion extending outwardly from the planar surface, and a flange portion rigid with the web portion and a spring clip device on the base plate biased outwardly from the planar surface and including a latching free edge. With each lug positioned in alignment with a respective aperture the spring clip is offset with respect to its associated aperture so that the door assembly may be mounted on the skin by placing the door handle assembly on the skin with the planar surface of the base plate juxtaposed to an outer surface of the skin, the lugs passing through a respective apertures, and the spring clip biased against a portion of the skin outer surface adjacent its associated aperture and thereafter moving the door handle assembly relative to the skin to move the web portion of each lug into engagement with an edge portion of a respective aperture, move the flange portion of each web beneath an inner surface of the skin and snap the clip free edge into engagement with the latching edge of the associated aperture.

Snap-on door handle assembly

A door handle assembly for a motor vehicle which acts to preclude inadvertent unlatching of the door in response to a side impact. The assembly includes a side impact detector member operative in response to a side impact against the door with the handle in its closed position to move inertially from a neutral position, allowing movement of the handle to its open position, to a side impact position, blocking movement of the handle to its open position. The door handle assembly includes an actuator lever operated by the door handle and mounted for pivotal movement in response to movement of the handle, and the side impact detector member comprises a lever pivotally mounted on the actuator lever. The side impact lever normally forms a linear extension of the actuator lever but pivots inertially relative to the actuator lever in response to side impact to a position blocking opening movement of the handle.
