Abstract
An electric switch operating mechanism is disclosed for use with an electric lawn care appliance. The lawn care appliance has a housing, a switch and a movable bail which can be biased between active and inactive positions. An actuator is juxtaposed in between the bail and the switch. When the bail is moved to its active position, it causes the actuator to actuate the switch. The actuator has an engagement surface that engages with the bail to activate the mechanism. The switch further contains a button which enables the bail to engage the actuator.
Claims9
An electric lawn care device comprising:
- a driven member;
- a motor for driving said driven member;
- a switch for selectively switching power to said motor;
- an actuator operatively connected to said switch for selectively actuating said switch;
- a bail operatively connected to said actuator, said bail moveable between first and second positions, said bail causing said actuator to actuate said switch when said bail is in said second position;
- and,
- a spring, said spring biasing said bail to said first position, said spring interconnecting said bail to said actuator, said spring comprising:
- an extension (70), said extension (70) engaging said actuator and causing said actuator to actuate said switch when said bail is in said second position;
- said actuator comprising:
- an engagement surface, said extension engaging said actuator at said engagement surface;
- and,
- a barrier, said barrier selectively preventing said extension from engaging said engagement surface;
- said bail comprising:
- a slot for receivingly interconnecting said extension to said bail.
An electric lawn care device comprising:
- a driven member;
- a motor for driving said driven member;
- a switch for selectively switching power to said motor;
- an actuator operatively connected to said switch for selectively actuating said switch, said actuator having an engagement surface;
- a bail operatively connected to said actuator, said bail moveable between first and second positions, said bail causing said actuator to actuate said switch when said bail is in said second position;
- a spring comprising an extension, said spring interconnecting said bail to said actuator and biasing said bail to said first position, said extension engaging said actuator at said engagement surface and causing said actuator to actuate said switch when said bail is in said second position;
- a barrier, said barrier selectively preventing said extension from engaging said engagement surface;
- and,
- a button operatively connected to said extension wherein selective movement of said button by a user of said device selectively causes said extension to overcome said barrier.
