Embodiment Construction

[0026] figure 2 A sectional view showing the structure of the present invention, showing a state in which a passenger is waiting, image 3 It is an enlarged cross-sectional view of the main part, Figure 4 for image 3 separation diagram.

[0027] like Figure 2 to Figure 3 As shown, the safety device of the present invention is installed on the stepped portion of the door frame 10 of the elevator door. That is, between the door frame 10 and the hall door D of the elevator, a fixed frame 20 having a cross-section substantially in the shape of a "匚" is provided over the entire length of the stepped portion of the door frame 10 . Fasteners such as bolts or nuts are provided inside the fixed frame 20 so that the entire fixed frame 20 is fixed to the door frame 10 .

[0028] At one end of the fixed frame 20 , in particular, at one end of the side wall 22 of the fixed frame, a plate-shaped rotating frame 30 having a substantially “┐” shape in cross section is rotatably provid...

Abstract

The present invention relates to a safety device for preventing outward protrusions from an elevator door frame, and preventing hand jamming by giving off a warning light or a warning sound so as to warn a passenger of hand jamming while having a simple structure by using magnets, the safety device allowing a first magnet (50) and a second magnet (52) to approach each other such that current runstherethrough so as to stop the operation of an elevator hall door (D) or control the opening / closing speed thereof, while allowing a rotary frame (30) to rotate when the hand of a person is jammed ina gap between the door frame and a door, thereby preventing the hand of the person from entering the gap, and allowing the rotary frame (30) to rotate outward by a repulsive force between the same magnetic poles of the first magnet (40) and the second magnet (52) when external force acting on the rotary frame (30) disappears, and, at this point, allowing a stopping protrusion (32) of the rotary frame (30) to be caught by a stopper (42) of a support frame so as to prevent the rotary frame (30) from protruding outward from the door frame (10).

Description

technical field [0001] The present invention relates to an elevator anti-pinch hand safety device, in particular, to a safety device that prevents a rotating frame from protruding to the outside of a door frame, has a simple structure due to the use of a magnet, and issues a warning or a warning sound to warn passengers of being caught. hands to prevent pinching. Background technique [0002] In order to open and close the elevator door smoothly, there is a gap between the door D and the door frame 10. When a passenger waiting for the elevator puts his hand on the door in order to get on the elevator, it often happens that the door D does not realize that the door is opened. An accident in which the hand is caught in the gap between the door frame and the door when the hand is placed on the surface of the door. In particular, children have many such pinching accidents due to lack of attention. [0003] According to the statistics released by the Korean National Security Se...
