たりすることになる。In such a door closing device, in order to smoothly open and close the door and to ensure good airtightness and sound insulation, the closing member is provided with a floor just before the door is closed. Although it is desirable to abut against the surface, it is generally difficult to adjust the timing between the closing of the closing member and the closing of the door. Although the opening and closing of the opening becomes smooth, the pressure contact state of the closing member against the floor surface is incomplete, so that a draft is generated or the soundproof effect is not sufficiently obtained.

隙間を閉塞する。When the door is opened, the contact state of the protruding member with the door frame side is released by the rotation of the door, so that the spring is extended by its elasticity, and the closing member connected to the spring is raised. By doing so, the closed state of the gap is released, and the door is smoothly opened and closed. Further, when the door is closed, the projecting member comes into contact with the door frame or a member provided on the door frame side to perform a retraction operation, whereby the spring bends downward, whereby the closing member is closed. It protrudes downward and closes the gap between it and the floor.

る。At this time, since the spring is mounted at a position where the center of the deflection is shifted from the center position in the width direction of the door to the hanging side, the spring is moved from the center of the closing member by the bending. Since the side position is pushed downward, and the load is biased to the hanging side of the closing member, the closing member moves down from the hanging side to come into contact with the floor surface, and As the sliding distance on the side becomes shorter and the load on the door tip side becomes smaller, the opening and closing of the door becomes smoother, and the abrasion and damage of the closing member are reduced.

できる。At this time, since the leaf spring 2 is attached to the hanging side from the center of the latent door 26, the position of the closing member 3 near the hanging side is pressed downward, and the load is reduced. Since the closing member 3 is biased toward the hanging side, the closing member 3 comes into contact with the floor surface 28 from the hanging side, so that the sliding distance on the door side is reduced and the load on the door side is reduced. Because of this reduction, the opening and closing of the latent door 26 becomes smooth, and the wear and breakage of the closing member 3 can be reduced.

る。As described above, the door closing device according to the present invention has the above structure, in particular, a spring which presses down the closing member by bending downward so that the center of the bending is shifted from the center position in the width direction of the door. The structure is mounted so that it is located closer to the hanging side, so that a sufficient pressure-contact state with the floor surface can be ensured, without impairing the airtightness and sound insulation performance. Because the pushing force is applied to the position biased to the hanging side of the closing member, the closing member descends from the hanging side first and gradually comes into contact with the floor surface toward the door end side. In addition, the sliding distance of the closing member on the door tip side can be shortened, the door can be opened and closed smoothly, and an excellent effect of preventing wear and breakage of the closing member can be obtained. is there.
