The collision with the outer frame 2 generates an impact sound, which causes noise and nuisance to residents on the upper or lower floors of apartments, etc. This device aims to improve such drawbacks. What has been done is that a strong permanent magnet 3 is attached to the outer frame 2 of a certain door.
When passing under the door 1, a flow is generated at the metal plate 4 made of aluminum or the like attached to the top of the door 1, and the door 1 receives a resistance force, and the resistance force that the door 1 receives as it is decelerated is Since the size increases in proportion to the speed of movement of the door 1, in the case of an aluminum door and outer frame, which has a great noise-damping effect, the metal plate 4 that pairs with the strong permanent magnet 3 is not particularly necessary. The strong permanent magnet 3 and metal plate 4 may be attached to a revolving door as shown in Figure 4.M as in the case of a sliding door.
The permanent magnet 3 and the metal plate 4, which have an impact effect, should be installed in opposite positions.Instead of the metal plate 4, a coil with a closed circuit may be used, but if an induced current is generated in the coil, occurs and a buffering effect appears.
