Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view illustrating an elevator lifting prevention apparatus.

Referring to FIG. 1, an elevator lifting prevention apparatus 100 according to an embodiment of the present invention includes a fall prevention plate 110 and a spring 120.

When the elevator door 210 is opened, the fall prevention plate 110 is located below the floor of the elevator hall meaning the front space of the elevator. When the elevator door 210 is opened, the fall prevention plate 110 is moved to the elevator silo, It is possible to prevent a falling accident that may occur due to entering the silo.

In other words, the fall prevention plate 110 is located in the elevator silo when the elevator door 210 is opened even though the elevator chamber 220 is not located behind the elevator door, so that the passenger can unintentionally lift the elevator door 210 into the elevator silo It is a component that enables you to prevent a falling accident that may occur when you enter.

Here, since the fall prevention plate 110 is a part of the passenger's foot, it is desirable that the fall prevention plate 110 is strong and wide enough to withstand the loads of many passengers.

The spring 120 moves the fall prevention plate 110 to the elevated silo using the restoring force.

If the device has elasticity and can generate a restoring force, it can be used instead of the spring 120.

One of the corners constituting the fall prevention plate 110 forms an acute angle with the guide plate 212 which is attached to the lower end of each elevator door 210 and extends downward.

In this case, when the height of the elevator door 210 and the height of the fall prevention plate 110 are different from each other, the fall prevention plate 110 is moved in accordance with the opening and closing of the elevator door 210 It is the role of the guide to make.

The reason why the elevator door 210 is formed in contact with the elevator door 210 is because the elevator door 210 is opened and closed by the spring 120 having an elastic force in a direction perpendicular to the moving direction of the guide plate 212 and the elevator door 210 So that the movement of the prevention plate 110 is guided.

In other words, by forming the acute angle, the fall prevention plate 110 moves from the elevator hall to the elevator silo as the elevator door 210 is opened, as shown in Figs. 3A to 3C, The fall preventing plate 110 can be returned from the elevator silo back to the floor of the elevator hall.

At this time, as the acute angle formed by the guide plate 212 and the fall prevention plate 110 is smaller, the force received in the direction in which the fall prevention plate 110 moves becomes larger, so that the acute angle is preferably small.

As the elevator door 210 is closed, each of the guide plates 212 moves left and right in a direction of centering, and the fall prevention plate 110 moves in a direction to be inserted into the fall prevention case 130.

At this time, the guide plate 212 includes a roller (not shown) at a portion contacting the fall prevention plate 110, so that the fall prevention plate 110 is moved by the contact rotation of the roller, This can be achieved smoothly.

The apparatus 100 may further include a fall prevention case 130 which is fixed below the floor of the elevator hall and in which the fall prevention plate 110 is located when the elevator door 210 is closed.

The fall prevention case 130 includes a spring 120 as a space in which the fall prevention plate 110 is inserted when the elevator door is closed.

Here, one end of the spring 120 is connected to the fall prevention plate 110, and the other end is connected to the fall prevention case 130.

The lifting device 100 of the elevator further includes a load cell 140 positioned above the fall prevention plate 110 and a notification unit (not shown) generating a notification when a load is detected on the load cell 140 can do.

The load cell 140 senses a load when the passenger touches the load cell 140. When a load is detected by the load cell 140, the notification unit may generate a notification using visual or auditory information to warn the passenger.

For example, when the elevator door 220 is opened but the elevator door 210 is opened, the fall prevention plate 110 is moved to the silo, the passenger mistakenly thinks that the elevator chamber 220 is present, ), You can make the warning light glow or beep.

2A is a view for explaining a state of an elevator lifting prevention apparatus according to an embodiment of the present invention when the elevator door is closed.

Referring to FIG. 2A, the fall-prevention plate 110 is positioned below the hall of the elevator when the elevator door is closed.

FIG. 2B is a view for explaining a state of an elevator lifting prevention apparatus according to an embodiment of the present invention when the elevator door is opened.

Referring to FIG. 2B, when the elevator door is opened, the fall prevention plate 110 is moved to the elevator silo by the restoring force of the spring. When the elevator chamber 220 is positioned behind the elevator door 210, The elevator door 110 is located below the elevator chamber 220 but is exposed to passengers so that the elevator chamber 220 is not behind the elevator door 210.

FIGS. 3A to 3C are views for explaining the operation principle of the lifting device for the life of an elevator according to an embodiment of the present invention.

3A to 3C are views showing an elevator lifting prevention apparatus 100 viewed from an upper surface of an elevator door 220 and an elevator door 220. When the elevator door 210 is opened And the fall prevention plate 110 moves from the elevator hall to the elevator silo.

According to the reverse order, it can be understood that the fall prevention plate 110 moves from the elevator silo to the elevator hall as the elevator door 210 is closed.

3A to 3C, as the elevator door 210 is opened, the guide plate 212 also moves in the direction away from the both sides. As the guide plate 212 moves, the fall prevention plate 110 is also moved to the elevator silo .

When the elevator door 210 is closed, the guide plate 212 is moved in the direction of approaching each other again. As the guide plate 212 moves, the fall prevention plate 110 also moves back to the elevator hall.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
