<p><P>PROBLEM TO BE SOLVED: To solve the problem that it is hard to open a door by operating a swing type pressurizing body (different solving means) utilizing the principle of leverage so as to "kick it out" to an abutting part on a door frame side, without giving component force in an opening direction to a door itself by "breaking the door open." <P>SOLUTION: For a device for dissolving a difference between inside and outside pressures in a latch lock, to the lock box of the latch lock, a drive member to be slid by operation force of operation means, a slide control body engaged with the drive member at the rear end part to be slid against energizing force of energizing means to the front side of the lock box by the drive force of the drive member, and a swing type pressurizing body linked to the distal end part of the slide control body at the inner end through connection means and pivoted through a vertical shaft are incorporated respectively. When opening the door, when the engaging distal end part of the swing type pressurizing body are brought into press contact so as to be kicked out to the abutting part on the door frame side through the drive member operated by the operation force of the operation means and the slide control body, all reaction based on press contact force acts in the direction of opening the door itself. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
