| 摘要 |
There is disclosed an automatic sliding door closing device comprised of two elongated arms coupled together at their proximal ends by a coiled spring which spreads the distal ends of the elongated arms apart. The distal end of one elongated arm is attached to a door jamb and the distal end of the other elongated arm is attached to the edge of the sliding door. Speed damping is provided by a pneumatic cylinder which retards the acceleration of the sliding door due to the force exerted by the coiled spring.
