Safety device of elevator for hand protection

Abstract

The present invention relates to a safety device which reduces shocks and controls the opening / closing of a door of an elevator to prevent hands from being pinched in the elevator when hands of a user are pinched between the elevator door and a doorframe. The device comprises: a fixing frame where a cross-section, installed across the overall length of a stopper protrusion unit of a doorframe between the doorframe of an elevator door and a hall door of the elevator, is formed as an U shape; a rotating frame which is formed as a plate and installed to be able to rotate on one end portion of the fixing frame ; an operating pin which is installed in the fixing frame to support the back surface of the rotating frame, is supported by a spiral spring, is put towards the inside of the fixing frame by means of the rotation of the rotating frame, and protrudes towards the outside of the fixing frame by means of elasticity of the spiral spring; a switch which is installed in the inside of the fixing frame to be operated if the operating pin is put into the inside of the fixing frame by means of the rotation of the rotating frame; and a controller which is connected to the switch and stops the operation of the hall door of the elevator or controls the speed of the opening / closing of the elevator when the switch is operated.

Description

technical field [0001] The present invention relates to an elevator anti-pinching safety device, in particular to a safety device for preventing hand pinching by controlling the opening and closing of the door while reducing the impact when a person's hand is caught in the gap between the elevator door and the door frame device. Background technique [0002] In order for the elevator door D to open and close smoothly, there is a gap between the door D and the door frame 10, and when passengers waiting at the hall put their hands on the door surface to get on the elevator, the opening of the door D cannot be recognized. , so that under the state that the handle rests on the surface of the door, frequent accidents in which the hand is caught in the gap between the door frame and the door and is injured. Especially, under the situation of children, because of lack of attention, the above-mentioned safety accident of pinching often takes place. [0003] According to the statis...

Problems solved by technology

Since the passenger's hand is particularly easy to access this middle part, and the conventional device 12 does not have the function of adjusting such a gap, there is a problem that it cannot prevent the passenger's hand from being caught in the middle part, etc., which is larger than the original gap. in the gap

[0008] In addition, after installing the conventional device, if time passes, the device will sag due to its own weight and come into contact with the ground, causing the problem of friction.

[0009] In addition, since conventional devices require installation and maintenance inside the elevator, there is a problem that workers are exposed to dangerous environments.
