Snap fastener 20 is configured to, and is being about at closing time, prepares for the car lifting closed behind the door and makes engaging depart from.

Fig. 3 is the enlarged drawing of the dotted portion shown in Fig. 2. As shown in the drawing, at the side end 11 of hall door-plate 1a, the seam component 30 substantially in "U" i section is installed in the gamut from top to bottom of hall door 1 when having viewed from above.Seam component 30 is such as that aluminum etc. is metal. In seam component 30, it is formed with inclined plane (the 1st inclined plane) 30a tilted to enabling direction with tiltangleθ near the central part of the thickness of hall door-plate 1a as summit.

It addition, as it is shown on figure 3, more lean on the side of hall to be configured with by the containment member 33 that such as flexible material such as rubber, elastomer is constituted on the end face of the side, direction of closing the door of seam component 30, compared with the centrage X of the thickness for hall door-plate 1a. Containment member 33 is breaking at, at hall door-plate 1a, 1b, the air-flow flow through between hall and lift path at closing time.

It addition, containment member 33 have using hall side as summit to from door knob direction away from direction tilt inclined plane 33a (the 2nd inclined plane). This inclined plane 33a is positioned at from the inclined plane 30a of seam component 30 to the extended line in hall direction, is formed in the same manner as inclined plane 30a in the way of inclined angle θ. That is, in the present embodiment, the door knob face 35 being positioned at the side, direction of closing the door of hall door-plate 1a, 1b includes the inclined plane 30a of seam the component 30 and inclined plane 33a of containment member 33. Here, the tiltangleθ in door knob face 35 is set to 2 °～about 10 °.

The leading section 31 of the hall side of seam component 30 is in compared with the summit of containment member 33 to the position that have dropped with direction of closing the door (arrow B direction) opposite direction and enabling direction, makes in the shape not contacted with the leading section 31 of the hall door-plate 1b of opposition side at closing time.

<effect of above-mentioned embodiment confirms experiment>

The impact that door closing force is produced by present inventor for the shape investigating the side end 11 (hereinafter referred to as " end of closing the door ") in the direction of closing the door of hall door 1, uses the model of door to test. In an experiment, apply blast with the side being equivalent to hall of the model of the support structure of the aerator hall door to simulating reality, the door measured in pair of right and left door with digital ergometer be fixed on closed position in advance and make another from reach close time required power. Figure 13 to Figure 16 is the figure of hall door 1 and experimental data (1)～(4) in the comparative test of conventional hall door illustrating embodiment of the present utility model. In fig. 13, transverse axis is gap of closing the door, with standard-sized sheet being set to 100, being represented by the fully closed percentage ratio being set to 0.Left vertical is pressure, will be set to 100% at the maximum differential pressure produced at closing time. Right vertical is required power of closing the door, and represents with the percentage ratio that the power at the end place of closing the door when being shaped as shape A of end of closing the door is set to 100. In Figure 14 to Figure 16, about the data (shape B, C, D) of other end shapes, represent door closing force for benchmark (100%) with percentage ratio with the masterpiece at the end place of closing the door of shape A.

When the shape A shown in Figure 13, door end face is only plane as the one side of cuboid. In this case, if gap of closing the door is lower than 3%, then door closing force steeply rises and the power that becomes maximum at end place of closing the door.

When the shape B shown in Figure 14, in the same manner as the situation of the 1st and the 3rd embodiment, the upstream side (hall side) at wind is provided with the flank being equivalent to containment member. In this case, do not observe steeply rising of the door closing force being about at closing time, door closing force is shape A about the 60% of end place of closing the door.

When the shape C shown in Figure 15, contrary with Figure 14, the downstream side at wind is provided with flank. In this case, close door closing force in front of the door and rise more anxious compared with shape A, door closing force is shape A the 170% of end place of closing the door.

Shape A, shape C the high reason of the door closing force at end place of closing the door be considered as that the pressure in hall side at closing time enters into and closes the door in gap, this pressure creates the power pushing back the door end face that will close. According to these experiments it has been confirmed that pass through to be set to shape B, it is possible to reduce door closing force.

It addition, when the shape D shown in Figure 16, in the same manner as the situation of the 1st and the 4th embodiment, make door knob face tilt. Experimental result is the situation making door knob face tilt 3 °. In this case, door closing force is shown greatly null value along with closing the door and is elapsed, if gap of closing the door is more than 15%, then door closing force becomes negative. Namely, it is known that the power in the direction closed by door just works. This power reaches lower limit when closing the door gap 2%, thereafter then rise, become at final end place of closing the door shape A 50% power. When shape D, the crest line of the hall side with the door knob face of inclination first connects, so when door knob, with shape B the same effect being can be observed. By this experiment, it is thus identified that the inclination in door knob face makes resistance reduction of closing the door, and then produces the power that auxiliary is closed the door.
