Abstract
A luggage-door lock device includes a latch having a pawl engaged with a striker secured to a body and a spring urging the pawl towards the striker. The engagement is assured by the engagement between the latch and a swing member, by removing the swing member from the latch as a result of a motor-operated mechanism, so that the pawl is removed from the striker. Due to the reaction of the spring after resulting removal, a lid to which the latch is secured is moved in an opening direction.

A luggage-door lock device comprising:
- a body having therein a space and provided with an opening through which the space is accessible;
- a striker element secured to a portion of the body adjacent the opening of the body;
- lid means pivoted to the body for closing the opening of the body;
- a base secured to the lid;
- latch means provided with a pawl and movable between a first position at which the pawl is in engagement with the striker and a second position at which the pawl is in full disengagement with striker;
- a swing member pivoted to the base and having a shoulder portion engageable with the latch at the first position;
- spring means disposed between the swing member and the latch so that engagement therebetween is maintained and the latch is urged continually towards the second position;
- a motor having a shaft including a worm gear;
- a worm-wheel provided at a peripheral portion thereof with a geared-portion engaged with the worm so that rotation is transmitted from the worm to the geared portion and vice versa, and having a projection engagable with the swing member and mounted rotatably on the base;
