| 摘要 | PURPOSE: To improve adaptability to a cordless and rechargeable dynamo-electric means by controlling a function of an interlock switch by using a key member and switching on and off a power circuit. CONSTITUTION: When a mechanical key member 20 is completely inserted into an opening part on an enclosure 14 of a motor, it is engaged with a plunger 35 of a normally-open interlock switch 32, the switch 32 is closed by its cam, and a power circuit of a lawn mower is switched on. Simultaneously, a tub part of the key member 20 blocks a charging port 50, and a worker cannot insert an output plug of a charging transformer into a charging circuit. Additionally, when the key member 20 is removed from an enclosure 14, the switch 32 returns to its opened position, and the power circuit of the lawn mower is switched off. At this time, the charging port 50 is further exposed, and the charging circuit can be connected to the charging transformer. COPYRIGHT: (C)1992,JPO |
