An operating shaft 30 is provided on the lower side of the door 5 so as to be linearly movable in the door width direction. In this embodiment, the operation shaft 30 is supported by the square panel 20 having a "∩" -shaped cross section is installed.

The working shaft 30 is inserted into both bearing stands 11 and 12 of the square panel 20 so as to be linearly supported, and the bearing stands 11 and 12 are fixedly installed in the square panel 20.

The shielding plate 40 is connected to the working shaft 30 via a link means to be described later. The shielding plate 40 is moved up and down in association with the linear movement direction of the operating shaft 30. At this time, the shielding plate 40 blocks the gap G as shown in FIG. 4A when the bottom surface thereof reaches the bottom 1 when descending. At this time, the shielding plate 40 is located in the lifting height L of the floor hinge arm 7. The lifting height L is preferably in the range of 10 to 50 mm.

In this way, the link means is provided as a motion conversion method for the shielding plate 40 is lifted and operated in conjunction with the operation shaft 30. In the present embodiment, the link means is composed of an L-shaped link 50 rotatably connected to the rectangular panel 20 by a hinge pin 51. In the present embodiment, two links 50 are provided and arranged on both sides, but the present invention is not limited to these installation numbers. The link 50 functions to connect the operating shaft 30 and the shield plate 40 to convert the linear movement of the operating shaft 30 into the lifting movement on the shield plate 40 side.

The link 50 forms a link hole 52 at one end thereof and has a link hinge pin 53 at the other end thereof, as shown in FIG. The fixing pin 31 of the operating shaft 30 is inserted into the link hole 52, and the link hinge pin 53 is inserted into the shield plate hole 41 of the shield plate 40.

In this configuration, the actuating shaft 30 is in the retracted movement position (completely moved to the right side in FIG. 3A) by the compression repulsive force of the spring 70, and the link 50 is given the rotational force in the clockwise direction In the closed state, the shield plate 40 is in a raised position, and the gap is opened.

In this state, when the operating shaft 30 is moved to the left by the force of the spring 70 by the permanent magnet 62 to be described later, the fixing pin 31 is guided to the link hole 52 and the link 50 Rotate counterclockwise, and the link side hinge pin 53 is guided to the long hole 41 to lower the shielding plate 40 to block the gap. At this time, the long holes 41 and 52 allow the position movement of the hinge pin 53 and the fixing pin 31, respectively.

As such, the link 50 is formed in an L-shape, and when the hinge pin 51 rotates about an axis, linear reciprocation of the operating shaft 30 is induced, and at the same time, the shield plate 40 moves upward and downward. Done.

The present invention is provided with operating shaft actuating means for the shield plate 40 to descend when the door 5 is closed.

On the other hand, when the door 5 is opened after the shield plate 40 is lowered, the return spring 70 is provided as a spring means for raising the shield plate 40 to the original position. The return spring 70 is supported at one end of the support shaft 70 and at the other end of the support spring 12.

Therefore, the working shaft 30 is subjected to a force pulled to the right in Figure 3a by the elastic repulsive force of the return spring (70).

On the other hand, the present invention may be further provided with a speed adjusting device 100 for adjusting the speed of the operating shaft (30). This is because the closing (falling) operation of the shielding plate 40 is made gradually when the door 5 is closed, and the opening (rising) operation of the shielding plate 40 is quickly performed when the door 5 is opened.

To this end, a valve housing 110 inserted into the operating shaft 30 and fixedly supported on the door 5 side is provided, and the operating shaft 30 has an air pressure plate 120 sliding in the valve housing 110. The seat valve 130 is fixedly installed, and adjusts the movement speed of the operating shaft 30 by adjusting the amount of air flowing in and out of the valve housing 110 according to the movement direction of the air pressure plate 120 in the valve housing 110. ) Is arranged.

Here, the spring support plate 140 may be further provided when the return spring 70 is installed in the valve housing 110. A plurality of air holes 140a are formed in the spring support plate 140.

When the speed adjusting device 100 configured as described above pulls the operating shaft 30 by the suction force between the permanent magnets 60 and 62 when the door 5 reaches the closed position, the air pressure plate 120 is thereby pulled out. As shown in FIG. 4B, the air in the valve housing 110 is compressed. The compressed air pushes the seat valve 130 toward the valve housing 110 to block the air hole 110a.

Therefore, since the compressed air receives resistance through only the shaft holes 130a and 110b of the seat valve 130 and the valve housing 110, the operating shaft 30 gradually moves, and as a result, a link ( Shield plate 40 connected via 50) is gradually lowered to shield the gap.

In this state, when the door 5 is opened, the suction force acting on the door-side permanent magnet 60 disappears, and the air pressure plate 120 moves back to its original position by the elastic repulsive force of the return spring 70. At this time, a negative pressure is generated in the valve housing 110 so that the seat valve 130 moves backward.

Due to this, more air is supplied to the opened air hole 110a and flows into the valve housing 110, so that the retreat movement speed of the operating shaft 30 is increased, and as a result, the link 50 is connected to the operating shaft 30 through the link 50. The interlocked shield plate 40 is rapidly rising.

It is inserted into the) is composed of a seat valve 270 to adjust the retraction speed of the door frame blocking plate 210 by varying the amount of air flowing into the valve housing 250 according to the moving direction of the door frame shaft operation shaft 230.

At this time, the seat valve 270 is disposed between the spring support plate 252 receives the return spring 240 force, the spring support plate 252 is formed with a plurality of air holes (252a).

When the door frame shielding means 200 configured as described above pulls the operating shaft 230 by the suction force between the permanent magnets 60 and 220 when the door 5 reaches the closed position, the air pressure plate 260 The air in the valve housing 250 is compressed, and the compressed air pushes the seat valve 270 toward the valve housing 250 to block the air hole 250a.

Therefore, since the compressed air receives resistance through only the seat valve 270 into which the door frame side operating shaft 230 is inserted and the insertion holes 270a and 250b of the valve housing 250, the operating shaft 230 gradually moves, As a result, the door frame blocking plate 210 connected to the operation shaft 230 gradually operates to shield the door frame gap.

On the other hand, when the door 5 is opened after the shielding, the adsorption force acting on the door-side permanent magnet 220 disappears, and the air pressure plate 260 moves back to its original position by the elastic repulsive force of the return spring 240. At this time, a negative pressure is generated in the valve housing 250 so that the seat valve 270 is retracted to be in close contact with the spring support plate 252. Due to this, more air is supplied to the opened air hole 250a and flows into the valve housing 250 so that the retraction movement speed of the operating shaft 230 is increased, and as a result, the door frame blocking plate 210 connected to the operating shaft 230 is provided. Quickly returns to its original position.
