Description

Elevator Escape and Fall Prevention System The present invention is applied to an elevator, and more specifically, to an elevator escape and fall prevention system that allows passengers to escape quickly and easily with external assistance when the elevator car stops at an abnormal position due to a power outage or malfunction during elevator operation, while preventing them from falling into the elevator shaft during the escape, thereby greatly improving safety. Generally, an elevator is a facility installed inside a high-rise building in which a lift car moves vertically up and down driven by a motor to enable passengers to move between floors; it is installed and operated with various types of safety devices to ensure the maximum safety of passengers using it. As an example of the above safety device, a fall prevention plate is installed on the front of the lower frame of the elevator car to prevent falling into the elevator shaft when the elevator car stops at an abnormal position due to a malfunction or power outage during operation, thereby allowing passengers to easily escape. Recently, as shown in FIG. 1, a fall prevention plate (16) of a predetermined size is installed downwardly at the bottom of the elevator car, and one side of a support (18) is fixed to both sides of the metal plate, while the other side of the support (18) is firmly fixed to the bottom of the elevator car (10). This fall prevention device is designed so that when a passenger escapes from the elevator car (10), they are supported by the fall prevention plate (16) and can safely descend to the landing entrance (14), thereby preventing them from falling into the elevator shaft (12). However, since the fall prevention plate (16) must be installed with a length limited to a range that does not interfere with the operation of the elevator car (10), if the elevator car (10) is located at a somewhat higher position than the landing due to the limited length of the fall prevention plate (16), there is a risk that the escaping passenger may fall into the elevator shaft (12) due to the gap between the bottom of the fall prevention plate (16) and the landing, which is a large The current situation is that it is not yielding effective results. To resolve these problems, an elevator car equipped with a fall prevention device according to Patent Registration No. 10-0638258 was proposed to the applicant of the present invention, the configuration thereof comprising: an elevator car installed inside a building to facilitate the smooth movement of passengers between floors, wherein a plurality of fastening holes are formed through the upper front portion so as to be firmly fastened to the front of the lower frame of the elevator car using fastening means such as bolts and nuts, and a plurality of fastening holes are formed through the upper and lower portions of a support member so as to be fixed by bolts and nuts respectively, and a fixed plate having a predetermined area in the center cut to form a cut portion, wherein each protruding piece having a hinge hole formed on each upper side of the cut portion is protruded backward; and a fall prevention plate having an area identical to the cut portion of the fixed plate, wherein each protruding piece having a hinge hole formed on each upper end is integrally protruded so as to be hinge-coupled to the cut portion and rotatably fixed. The configuration includes a support means for vertically installing air cylinders, each end of which is rotatably hinged to a plurality of fixing brackets installed and fixed on both sides of the rear upper portion of the fixed plate and on both sides of the rear lower portion of the fall prevention plate, to support the fall prevention plate so that it is maintained at a predetermined angle of inclination toward the landing door during an emergency escape; and a locking member installed on both sides of the cut portion on the fixed plate to firmly fix the fall prevention plate to the fixed plate under normal conditions. Although this fall prevention device allowed passengers to escape quickly and safely, there were difficulties in operation because a large force had to be applied to rotate the fall prevention plate and the support means simultaneously, and the safety of escape could not be fully ensured, such as when passengers slipped and fell to the platform floor during escape because the fall prevention plate was located in front of the support means.
