I have. Each door 2a, 2b is supported by a base end portion (not shown) so as to be rotatable in both the indoor direction (arrow A direction) and the outdoor direction (arrow B direction). Moreover, each door 2a, 2b is provided with the summing parts 4a, 4b provided in the front-end | tip part.

  The summing portions 4a and 4b are provided on the front end surfaces of the doors 2a and 2b so as to extend in the vertical direction over the entire height of the doors 2a and 2b, and as shown in FIG. It is comprised so that the clearance gap between the front-end | tip parts may be plugged up.

  Each summing portion 4a, 4b includes plate bodies 6a, 6b made of a ferromagnetic material such as steel, and seal members 8a, 8b. The plate bodies 6a and 6b have a length substantially equal to the height of the doors 2a and 2b, and are deeply recessed grooves 10a and 10b provided on the front end surfaces of the doors 2a and 2b so as to extend in the vertical direction over the entire height of the door. It is being fixed to wall 12a, 12b (base end side wall). The concave grooves 10a and 10b are configured by members 16a and 16b having rectangular closed cross sections which are disposed on the side surfaces of the doors 2a and 2b and have elongated openings 14a and 14b extending in the vertical direction.

  FIG. 2 is a schematic perspective view showing the configuration of the seal members 8a and 8b. As shown in FIG. 2, the seal members 8a and 8b include base portions 18a and 18b having a rectangular closed cross-sectional shape, and thin plate-like fins 20a and 20b extending outward from one side surface of the base portions 18a and 18b. And rod-shaped permanent magnets 22a and 22b having rectangular cross sections accommodated in the closed cross sections of the base portions 18a and 18b. The bases 18a and 18b and the fins 20a and 20b are integrally formed of a flexible material such as silicon rubber.

  The seal members 8a and 8b are formed on the other side surfaces 26a and 26b opposite to the side surfaces 24a and 24b on which the fins 20a and 20b of the base portions 18a and 18b are formed by the magnetic force of the permanent magnets 22a and 22b accommodated in the base portions 18a and 18b. Is adsorbed to the plate bodies 6a and 6b, and is detachably attached to the doors 2a and 2b in the concave grooves 10a and 10b. The width W1 of the base portions 18a and 18b of the seal members 8a and 8b is set to be larger than the width W2 of the opening of the concave groove.

  When the sealing members 8a and 8b are installed in the concave grooves 10a and 10b, the fins 20a and 20b have two tips protruding from the openings 14a and 14b outward (toward the tip side). When the doors 2a and 2b are in the closed state, as shown in FIG. 1, the tip portions of the doors 2a and 2b are engaged (overlapped) to close the gap between the tip portions of the two doors 2a and 2b. It is configured as follows.

  Next, the operation of the summing unit of this embodiment will be described with reference to the drawings. 3 and 4 are enlarged views showing the movement of the summing unit according to the present embodiment.

  In the state shown in FIG. 1, the fins 20 a and 20 b of the two doors 2 a and 2 b engage with each other when the two doors 2 a and 2 b are in a closed state (overlapping). The tip of the two doors 2a and 2b with the fin 20a of the seal member 8a in the left door 2a arranged outside the room and the 20bb of the seal member 8b in the right door 2b arranged inside the room The gap between is closed. At this time, the seal members 8a and 8b of the two doors 2a and 2b are moved to the other side surfaces 26a and 26b (fins) of the base portions 18a and 18b by the magnetic force of the permanent magnets 22a and 22b accommodated in the base portions 18a and 18b. The one side surface 24a, 24b opposite to the side surface 20a, 20b is completely in contact with the plate bodies 6a, 6b.

  From this state, when the left door 2a is opened in the indoor direction (arrow A direction), if the left door 2a starts to rotate in the arrow A direction, the fin 20a of the seal member 8a of the left door 2a It is pressed in the outdoor direction by the fin 20b of the seal member 8b of the door 2b.

  At this time, if the moment acting on the seal member 19a by the pressing force against the fin 20a exceeds the attractive force due to the magnetic force between the permanent magnet 22a and the plate body 6a, the seal member 8a of the left door 2 causes the fin 20a to move. While bending, the indoor side portion of the base portion 18a is lifted from the plate body 6a and rotated in the outdoor direction. Further, as a result of the reaction, the sealing member 8b of the right door 2b also floats the fin 20b and the outdoor portion of the base portion 18b is lifted from the plate body 6b and rotates in the indoor direction.

  As a result of such rotation of the seal members 8a and 8b, the fins 20a and 20b are easily disengaged, and the force required to rotate the left door 2a in the indoor direction is reduced.

  When the left door 2a further rotates, the fin fins 20a and 20b are disengaged from each other, and the seal members 8a and 8b are caused by the magnetic force acting between the permanent magnets 22a and 22b and the plate bodies 6a and 6b. The other side surfaces 26a and 26b of the base portions 18a and 18b are attracted to the plate bodies 6a and 6b, and return to the initial position (FIG. 4).

  Such rotation of the seal members 8a and 8b also occurs when the right door 2b is opened in the outdoor direction (B direction).

  As described above, according to the present embodiment, there is provided a summing structure capable of reliably closing the gap between the double doors that can be opened and closed in both directions and reducing the force required for opening and closing in both directions. The

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention.
In the above embodiment, the arrow A direction is the indoor direction, but the door may be attached so that the arrow A direction is the outdoor direction.
