  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 4 show an embodiment of a home fence apparatus according to the present invention. The platform fence device 1 is provided on the track side of the floor surface of the platform 3 for passengers to get on and off the train. The platform fence device 1 is a box-shaped platform fence main body formed along the platform 3. 4 and door bodies 5 and 5 that are opened and closed from both sides of the platform fence main body 4 in conjunction with the train entrance door when the train stops at a fixed position of the platform 3. The home fence body 4 houses a drive mechanism for opening the door body 5 and a control circuit (none of which is shown) for controlling the drive mechanism.

  In addition, an intake port 6 is formed at a lower position on the home side surface of the home fence body 4, and an exhaust port (not shown) is formed at a lower position on the track side of the home fence body 4. A filter unit 7 is attached to the inside of the home fence body 4 so as to block the intake port 6.

  As shown in FIGS. 3 and 4, the filter unit 7 includes a filter frame body 8 having a substantially rectangular shape. A filter 10 is held on the side of the inlet 6 of the vertical frame of the filter frame 8. A plurality of plate-like magnets 11 extending in the vertical direction are provided on the inner side of the filter 10 of the filter frame 8. These magnets 11 are arranged in two rows in a plan view, and each row The magnets 11 are arranged so as to be displaced from each other in the lateral direction. As a result, air that has flowed in from the air inlet 6 and passed through the filter 10 passes between the magnets 11 and flows into the interior of the home fence body 4. Further, the filter frame body 8 is detachably attached to the inside of the air inlet 6 of the home fence body 4 by a holding metal fitting 12.

  Further, in the present embodiment, a valve mechanism (not shown) is disposed at each of the inlet 6 and the exhaust outlet of the home fence body 4, and the home fence body 4 draws outside air only from the inlet 6 by this valve mechanism. The interior air of the home fence body 4 is discharged to the outside only from the exhaust port.

  Next, the operation of this embodiment will be described.

  In the present embodiment, the door 5 is opened and closed by stopping the train on the platform 3 and driving the drive mechanism by the control circuit inside the platform fence device 1.

  In the present embodiment, when the door body 5 is opened, the door body 5 is drawn into the interior of the home fence body 4, so that the internal pressure of the home fence body 4 increases, but an exhaust port is formed. Therefore, the internal air of the home fence body 4 is discharged from the exhaust port to the track side of the home fence body 4. Further, when the door body 5 is closed, the door body 5 protrudes from the home fence body 4, so that the internal pressure of the home fence body 4 is reduced, but the intake port 6 is formed. Outside air on the platform side is introduced from the intake port 6.

  The outside air flowing in from the intake port 6 passes through the filter 10 to remove dust and the like. When the outside air that has passed through the filter 10 passes between the magnets 11, the iron powder is adsorbed by the magnetic force and flows into the home fence body 4. Therefore, the outside air flowing in from the air inlet 6 flows into the home fence body 4 in a state where the metal powder and dust are almost completely removed.

  As described above, in the present embodiment, the air inlet 6 is provided on the platform side surface of the home fence body 4, the exhaust port is provided on the track side surface of the home fence body 4, and the filter unit 7 is provided inside the air inlet 6. When the door 5 is closed, when the inside of the home fence main body 4 becomes a negative pressure, the outside air flowing in from the intake port 6 is made into metal by the filter 10 and the magnet 11. With the powder and dust almost completely removed, it will flow into the interior of the home fence body 4.
