Description

Safety device for preventing hands of elevator from being clamped by using safety contact plate

Technical Field

The present invention relates to a safety device for preventing pinching of hands of an elevator, and more particularly, to a safety device for preventing pinching of hands of an elevator, which prevents pinching of hands by controlling opening and closing of a door when the hands are pinched to a gap between an elevator door and a door frame using a safety touch panel.

Background

In order to smoothly open and close the elevator door D, there is a gap between the door D and the door frame 10, and in the case where a passenger waiting for the elevator places his or her hand on the door surface in order to get on the elevator, there is often an accident that the hand is caught in a gap between the door frame and the door without being aware of the opening of the door D and the hand is placed on the door surface, and is injured. In particular, children may experience many of these hand-pinching accidents due to lack of attention.

According to the statistical data issued by the korean national security department at 2016, 2, 19, 319 total security accidents occurred in the past 10 years, and the number of the dead people reached 365, wherein the number of the dead people reached 91. Among them, in the case of hand-pinching accidents, major accidents requiring treatment for 3 weeks or more occur every year, and the number of mild accidents hospitalized by korean consumers reaches 79 in 2013, 103 in 2014, and 92 in 2015. In order to prevent such an accident, the korean elevator law stipulates that the gap between the elevator door and the door frame is reduced from the former 10mm to 5 mm.

In order to solve the above-described problems, fig. 1 shows a conventional device using a security touch panel, in which a portion 1A is a front view and a portion 1B is a plan view showing a setting work flow.

In the present embodiment, the safety contact plate receiving the spring force is provided at the corner portion of the door frame 10 facing the door D to prevent the fingers of the passenger from being caught in the gap between the door frame and the door D, but as shown in fig. 1B showing the state before and after the safety contact plate is provided, if the safety contact plate is to be installed, the door D on the left side of the arrow is separated in advance as shown by the broken line, the corner portion of the door frame 10 is cut and the safety contact plate is provided, and thereafter, as shown in the diagram on the right side of the arrow, the door D needs to be readjusted to conform to the gap specification of 5mm, so that the installation work is very complicated.

Detailed Description

As shown in fig. 2, a buried box 20 is formed inside the door frame 10 along the length of the door frame 10 adjacent to the elevator door D. The landfill box 20 may have any shape as long as it has a box shape in which a long rectangular groove is formed in the door frame 10 and the assembly can be easily performed by a bolt, a screw, or the like. If the safety contact plate 30, the swing link 40, and the switch SW, which will be described later, are provided in the landfill tank 20, the landfill tank 20 itself becomes a module type, can be very easily installed in the door frame 10 by a simple fastening method, and can be easily replaced, and installation and maintenance thereof become very simple.

The safety contact plate 30 is movably provided in the landfill tank 20 in the overall length direction of the landfill tank 20, and the safety contact plate 30 is inserted into the landfill tank after protruding to the outside of the landfill tank by rotating the connecting rod 40. On the other hand, the surface portion of the safety contact plate 30 exposed to the outside may be covered with an elastic outer layer material.

As shown in fig. 2B, one or more rotation connecting rods 40 connected to the trolley 30 are provided inside the upper buried box 20. The rotation link 40 serves to protrude the safety contact plate 30 to the outside after the safety contact plate 30 is inserted to the inside. Specifically, as shown in a portion 2C of fig. 2, after the safety contact plate 30 is inserted into the interior by an external force, if the external force disappears, the rotation link 40 is rotated in the direction of the broken line arrow by the self weight of the safety contact plate 30, and the safety contact plate is protruded to the outside. That is, as shown in part 2B in fig. 2, the safety contact plate 30 is normally in a state of protruding toward the outside of the landfill tank 20. Alternatively, a spring or other pressurizing unit may be used instead of the rotating link 40.

The switch SW is provided inside the landfill box 20, and in a state where the safety contact plate 30 is protruded outward, the switch SW is not connected, and in a state where the safety contact plate 30 is inserted inside, the switch SW is connected, and the switch is connected to the elevator controller EC and the door controller DC, thereby controlling an open/close state of the elevator door D.

According to the structure of the present invention, when the safety contact plate 30 is inserted into the landfill box 20 by an external force and the switch SW is connected, the open/close state of the door is controlled by the elevator controller EC and the door controller DC, so that the operation of the door is stopped or the open/close speed of the door is slowed, thereby preventing the hand-pinching phenomenon in advance.

The landfill box 20 and the safety touch panel 30 of this structure are generally disposed in parallel with the elevator door D, but may be disposed in an angled manner according to the need.

Fig. 3 is a view showing an example arranged in an angled manner, a portion 3A is a sectional view showing a state before a pinching occurs, and a portion 3B is a sectional view showing a state after the pinching occurs.

As shown in the drawing, if the landfill tank 20 and the safety touch panel 30 are disposed in a manner of being inclined toward the surface of the door D, the passenger's hand can be more effectively prevented from being caught. Furthermore, the shape of the end of the safety touch panel 30 may take any shape that does not injure fingers according to the need.

In the present embodiment, the cross-sections of the landfill tank 20 and the safety contact plate 30 are arched in plan view, and therefore, the movement of the safety contact plate 30 is smoother, and the movement can be performed in a manner closer to the surface of the door, so that the phenomenon of pinching can be more effectively prevented.
