JPH10238197A - Device for opening and closing door body at the time of earthquake - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate the assembling of a device by mounting a lock device including a rolling spherical body on a top plate and fixing a frame body having an inclined surface and a push-up plate to a door body so that a door is automatically locked when an earthquake occurs to prevent the door from being opened. SOLUTION: Under conditions that a door 2 can be opened, if an earthquake occurs, a spherical body 9 in an upper room (a) vibrates horizontally and hits against a blade piece 10 so that a flange 4a of a lock rod 4 is turned and the rod 4 is disengaged from a spherical body 6 in a lower room (b), and hence the rod 4 falls down under gravitation to lock the door 2, preventing the door 2 from being freely opened. To unlock the door, a push-up plate 12 with a magnet 13 secured to a frame body 11 of the door 2 is caused to contact the tip of the rod to push the door 2 so that the rod 4 is pushed up. And a flange 4a of the rod 4 is supported by the body 6 and the plate 12 is lowered so that the door 2 can be opened and closed. And the rod 4 can be also pushed up by means of an inclined surface 11a. Thus a lock device, which is easily operated and can prevent the door from being opened, can be obtained.
