BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing device for a door provided at an entrance of an apartment or a condominium.

[0002]

2. Description of the Related Art
This type of door is supported by a door frame fixed to the entrance and the like so as to be openable and closable via a hinge, and this door is installed at an entrance facing an aisle like an apartment or a condominium. In the case where the door is mounted in an outwardly opening shape, there is a disadvantage that the door blocks the passage at the time of opening / closing and hinders passage.
Therefore, it is conceivable to attach the door in an inwardly opening shape. In such a case, however, the shoe sliding portion and the door stop portion of the door frame are exposed to the outside of the door. There is an inconvenience that water easily penetrates through the gap between the gaps, and the rain is a problem. And such a do
In the case of (1), ensure that the door is closed on the open side.

This invention SUMMARY OF THE INVENTION may, shall apply was conceived for the purpose of providing a sealing device for a door which can clean out these drawbacks in view of the above-mentioned circumstances, Tsumoto side The end is pivotally supported via a hinge
Abuts on the door frame of the door and on the open side of the fully closed door
A sealing member to seal the gap between the door and the door frame.
In closing, the sealing member is opened in the fully closed state.
Swing from the closed position in contact with the
A door to transform into a retracted position that deviates from the opening and closing locus of the edge
The sealing member is rotatably supported by a frame.
The retracting position by contacting the door-side portion of the door to be closed.
Actuating member for turning and transforming the sealing member into a closed posture
And the sealing member is urged to the evacuation position to retract the sealing member.
And an ammunition for maintaining the momentum . According to the present invention, it is possible to reliably prevent rainwater or the like from entering even if the provisional door is attached in an inward opening manner.

[0004]

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a metal door attached to an entrance of an apartment house or the like, and the door 1 has a hinge at a hanging side end with respect to a door frame 2 fixed to the four edges of the entrance (see FIG. (Not shown) so as to be rotatable in the horizontal direction, and is configured as a so-called inward-opening door that is opened toward the indoor side.

[0005] Reference numeral 3 denotes a sealing plate provided on the inner surface of the vertical frame 2a on the door end side of the door frame 2, and the sealing plate 3 has one side edge hinged over substantially the entire length of the vertical frame 2a. On the other hand, a rubber bead 4 in which a magnet is provided is provided on the other side edge.
In other words, the sealing plate 3 is in the retreat position for retreating from the opening / closing trajectory of the door 1 and the door 1 and the door frame 2 are in contact with the closed door 1.
In the closed position, the bead 4 is magnetically attached to the door 1 so that the gap between the door 1 and the door frame 2 is closed. Is to be sealed.

Further, 3a is the sealing plate (the sealing plate of the present invention).
An operating piece (corresponding to an operating member of the present invention ) integrally protruding from one side edge of the sealing plate 3, and the operating piece 3 a is arranged from one side edge of the sealing plate 3 in plan view. It extends in a substantially right angle direction, and is positioned on the opening / closing locus of the door 1 when the sealing plate 3 is in the retracted posture. That is, the operating piece 3a is rotated by the contact of the door 1 to be closed at the door end side portion, so that the integral sealing plate 3 is automatically changed to the closed posture. In addition, by always energizing the operating piece 3a with the ammunition device 5, it is ensured that the sealing plate 3 is positioned in the retracted position when the door 1 is opened, and the tip of the operating piece 3a is rotatable. By providing a round portion at the end of the door 1 on the side of the front end of the door 1 which is a contact position of the roller 6, the operating piece 3 a and the door 1 are provided.
Care has been taken to ensure smooth contact.

Further, reference numeral 7 denotes an upper and lower horizontal frame 2b of the door frame 2.
The sealing plate 7 functions in the same manner as the sealing plate 3 provided on the vertical frame 2b. However, in the case of the horizontal frame 2b, the operating piece 7a is connected to the horizontal frame 2b. 2b over the entire width, the contact timing of the hanging side portion and the door top side portion with respect to the door 1 is shifted, which hinders the rotation of the sealing plate 6, so that the operating piece 7a is attached to the door end side end portion. Only provided.

In the embodiment of the present invention configured as described above, the sealing plates 3 and 7 receive the urging force of the ammunition 5 toward the retreating posture side, but when the door 1 is closed, the operating piece is actuated. When the doors 3a and 7a come into contact with the door-side portion of the door 1, the door 3 automatically closes the gap between the door 1 and the door frame 2, and in this state, the beads provided on the sealing plates 3 and 7 are closed. By magnetically attaching the door 4 to the door 1, the gap between the door 1 and the door frame 2 is sealed.

As described above, according to the embodiment of the present invention, the door 1 is attached to the door frame 2 so that it can be opened and closed on the indoor side. The plates 3 and 7 automatically close the gap between the door 1 and the door frame 2. Therefore, even if the door 1 is mounted in an inwardly opened state so that the door does not obstruct the passage at the time of opening and closing and obstructs the passage, it is possible to reliably prevent a problem that rainwater easily enters the room as in the related art. As a result, it is possible to drastically improve the rain closing behavior of the inward opening door.

Moreover, in the embodiment, the sealing plates 3 and 7
By magnetically attaching the bead 4 on which the bead 4 containing the magnet is mounted to the door 1, the hermetic seal between the door 1 and the door frame 2 can be further ensured.

Further, since the sealing plates 3 and 7 are constantly urged to the retreating position side by the ammunition 5, the closing plates 3 and 7 are inadvertently displaced to the sealing position side when the door is opened, and become an obstacle. It is convenient without such troubles.

The present invention is, of course, not limited to the above-described embodiment. For example, a sealing plate is not provided on a vertical frame and a horizontal frame, but is provided only at an effective portion as necessary. Needless to say, this may be done.

[0013]
