Abstract
A control apparatus for a lawn mower which includes two coupling members pivotable about a single axis. The coupling members are connected to a drive mechanism and a braking mechanism for the lawn mower. The members are coupled so that a forward pushing force applied by the operator actuates forward driving movement of the lawn mower and a pulling force actuates the braking mechanism when the drive mechanism is placed in a forward gear.
Claims21
A lawn mower having an engine mounted on a main housing, cutting means contained in a cutter housing attached to the main housing and driven by the engine, and wheels attached to the main housing and driven by driving means, the improvement comprising:
- at least two coupling members pivotable about only a single axis;
- each of said coupling members being coupled to and capable of independently actuating the driving means;
- means for returning the driving means to a neutral configuration when external forces are absent;
- and
- the driving means being actuated to drive at least one side of the mower in substantially the same direction as a force applied to pivot one of said coupling members.
A control apparatus for a lawn mower, comprising:
- at least two coupling members pivotable about only a single axis;
- each of such said coupling members being coupled to and capable of actuating a drive means for said lawn mower and capable of operating independently from one another;
- means for returning said drive means to a neutral configuration when external forces are absent;
- and
- said drive means being actuated to drive at least one side of said mower in substantially the same direction as a force applied to pivot one of said coupling members.
A control apparatus for a lawn mower, comprising:
- at least two substantially elongate members pivotable between their ends about only a single axis;
- each of said substantially elongate members being substantially coupled to and capable of actuating a drive means for a lawn mower and capable of being independently operable from one another;
- means for returning said drive means to a neutral configuration when external forces are absent;
- and
- said drive means being actuated to drive at least one side of said mower in substantially the same direction as a force applied to pivot one of said substantially elongate members.
A control apparatus for a lawn mower, comprising:
- at least two substantially elongate members pivotable between their ends about a horizontal axis;
- each of said substantially elongate members being substantially coupled to and capable of actuating a drive means for a lawn mower and capable of being independently operable from one another;
- means for returning said drive means to a neutral configuration when external forces are absent;
- and
- said drive means being actuated to drive at least one side of said mower in substantially the same direction as a force applied to pivot one of said substantially elongate members.
A control apparatus for a lawn mower, comprising:
- at least two pivotable substantially polygonal-shaped members coupled substantially near their centers to a lawn mower handle;
- each of said substantially polygonal-shaped members being coupled to and capable of actuating a drive means for driving a lawn mower capable of being independently operable from one another;
- and
- said drive means being actuated to drive at least one side of a mower in substantially the same direction as a force applied to pivot one of said substantially polygonal-shaped members.
A control apparatus for a lawn mower, comprising:
- at least two pivotable substantially C-shaped members coupled substantially near their centers to a lawn mower handle;
- each of said substantially C-shaped members being substantially coupled to and capable of actuating a drive means for driving said lawn mower and capable of being independently operable from each other;
- and
- said drive means being actuated to drive at least one side of said mower in substantially the same direction as a force applied to pivot one of said substantially C-shaped members.
