Elevator safety device

An elevator safety device, comprising:

• a lower beam;
• and
• an emergency stop device mounted parallel to the lower beam in order to perform an emergency stop of an elevator car,
• wherein the lower beam comprises:
• a first side member;
• a second side member disposed opposite the first side member;
• a front support member configured to be coupled to and to support front portions of the first side member and the second side member;
• and
• a rear support member configured to be coupled to and to support rear portions of the first side member and the second side member,
• wherein the front support member and the rear support member comprise:
• bodies formed so as to surround the front and rear portions of the first side member and the second side member;
• slits vertically formed through the bodies in order to allow a first front surface of the first side member, a second front surface of the second side member, a first rear surface of the first side member, and a second rear surface of the second side member to be inserted therethrough and to protrude therefrom;
• and
• operation holes formed through the bodies in order to guide ascent and descent of a rotary control piece of the emergency stop device,
• wherein the rotary control piece is inserted through the operation holes,
• wherein the first and second side members comprise:
• first and second vertical surfaces having a rectangular plate shape;
• first and second upper surfaces and first and second lower surfaces bent and extending outwards from upper and lower end portions of the first and second vertical surfaces;
• first and second front surfaces extending from front portions of the first and second vertical surfaces;
• and
• first and second rear surfaces extending from rear portions of the first and second vertical surfaces,
• wherein the bodies comprise:
• vertical surfaces through which the slits and the operation holes are formed;
• upper surfaces bent and extending from upper end portions of the vertical surfaces so as to be seated on a first upper surface of the first side member and a second upper surface of the second side member;
• and
• lower surfaces bent and extending from lower end portions of the vertical surfaces so as to be seated on a first lower surface of the first side member and a second lower surface of the second side member;
• wherein the upper surfaces of the bodies contact with the first and second upper surfaces of the first and the second side member in surface to surface contact, and
• wherein the lower surfaces of the bodies contact with the first and second lower surfaces of the first and the second side member in surface to surface contact.
