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.

Claims

1. 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;

wherein said pawl includes a rubber-stopper which is brought into engagement with another rubber-stopper when said latch means is moved into said second position.

2. A luggage-door lock device according to the claim 1 further comprising a link mechanism through which a key-cylinder is operatively connected to the swing member.

4. A luggage door lock device according to claim 1 wherein said spring means extends axially when said latch means moves from said first position to said second position.

6. A luggage door lock device according to claim 1, further comprising return spring means for returning the worm-wheel to its original position upon completion of the rotation of the worm-wheel for disengaging the pawl and the striker.

3. 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; and

return-spring means for returning the worm-wheel to its original position upon completion of the rotation of the worm-wheel for disengaging the pawl and the striker;

wherein said pawl includes a rubber-stopper which is brought into engagement with another rubber-stopper when said latch means is moved into said second position.

5. 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; and

return-spring means for returning the worm-wheel to its original position upon completion of the rotation of the worm-wheel for disengaging the pawl and the striker;

wherein said swing member abuts a rubber-stopper when said latch mean sis moved into said second position.
