Embodiment Construction

[0028] figure 2 In order to show the sectional view of the structure of the present invention, showing the state of passengers waiting, image 3 An enlarged sectional view of the main part, Figure 4 for image 3 separation diagram.

[0029] like Figure 2 ~ Figure 3 As shown, the safety device of the present invention is installed on the step 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 fixing 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 fixing frame 20 , so that the entire fixing frame 20 is fixed to the door frame 10 .

[0030] At one end of the fixed frame 20 , especially at one end of the side wall 22 of the fixed frame, a plate-shaped rotary frame 30 with a cross-section substantially in the shape of a “┐” is rotatably provided. ...

Abstract

The present invention relates to a safety device as follows: a magnet and a high-frequency / ultrasonic switch are used to have a simple structure, and a warning light or a warning sound is issued to warn passengers that their hands are pinched to prevent hand pinching. Set between the first magnets (50) on the support frame (40), in order to prevent abnormal operation due to the influence of the magnetic force of the magnets, use a high-frequency switch or an ultrasonic switch as the first magnet (50) between the above-mentioned, set On the support frame (40), a switch (SW) connected to a controller (C) controlling the operation of the elevator and the elevator doors.

Description

technical field [0001] The present invention relates to an elevator anti-pinching safety device, in particular to the following safety device: using a magnet and a high-frequency / ultrasonic switch, the structure is simple, and a warning light or a warning sound is issued to warn passengers that their hands are pinched to prevent hand pinching. Background technique [0002] In order for the elevator door D to open and close smoothly, there is a distance between the door D and the door frame 10. When passengers waiting for the elevator put their hands on the door to get on the elevator, it often happens that the door D is not aware of it. Accidents in which the hand is caught in the gap between the door frame and the door while the door is open and the hand is placed on the surface, resulting in injury. In particular, children suffer from many such hand-clamping accidents due to lack of concentration. [0003] According to statistics released by the Korean National Security A...
