Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an elevator landing device, and particularly to an elevator landing device suitable for use in an automobile elevator or the like to prevent intrusion of automobiles.

[Conventional technology]

BACKGROUND ART In recent years, there has been an increase in accidents involving automobile elevators in which the car runs out of control due to a driver's operational error or the like and collides with the elevator landing door, and the landing door comes off due to this impact and falls into the hoistway. In order to prevent this type of accident,
As described in No. 116685, a protective plate is provided near the landing door, one side of which is rotatably attached to the landing floor and the other side of which is supported by a hydraulic ram, and the protective plate is moved by the operation of the hydraulic ram. It has been proposed to stand up from the landing floor only when the landing door is closed.

[Problem that the invention attempts to solve]

In the conventional technology proposed above, the protection plate and the hydraulic ram that drives the protection plate must be buried in the landing floor, and there is a problem in that a great deal of cost and labor is required for installation. Particularly when burying already delivered items, the work had to be completed at night or on holidays when elevators were not in use, which also caused problems. In addition, sufficient floor thickness is required for burying.
There were cases where it could not be installed in cases where the floor thickness was too small.

An object of the present invention is to provide an elevator landing device that is simple and can be freely installed.

[Means for solving problems]

A convex frame body with a gentle slope in the direction of travel of the automobile is provided on the landing floor in front of the landing door, and the frame body is provided with a frame body that stands up when the door is closed and stands up when the door is open. This can be achieved by providing a car stopper fence that is housed in a frame body in a horizontal state, and also by providing a device for driving the car stopper fence.

[Function] The car stopper fence housed within the frame body is in a horizontal state when the landing door is open, but
They are designed to stand up when the landing door is closed. This not only prevents the car from accidentally starting and colliding with the door even though the landing door is closed, but also allows the frame body to move freely.
It can be easily installed into existing equipment.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
1 is a building wall; 2 is a three-sided frame attached to the building wall 1; 3 is a landing door that opens and closes automatically; 4 is an operation switch for calling a car; 6 is the landing floor facing the landing door 3, 7 is the indicator that prompts the progress or stop of the
A convex frame body with a gentle slope in the direction of travel of the car, 8 stands up when the landing door 3 is closed and remains horizontal when it is open, and 9 is a box body. , There is a car stop fence 8 inside this box.
Drive motor 1 that raises or horizontally
2. Chain 13, a drive device in which a support shaft 14 for transmitting power to the car stop fence is housed; 10, a storage groove in which the car stop fence 8 is stored when it is in a horizontal state; 11;
15a and 15b are limit switches for stopping the rotation of the small gear motor 12, and 16 are anchor bolts for fixing the frame body 7 to the landing floor 6. It is.

Now, however, when the elevator landing door 3 is in the closed state, the car stop fence 8 provided on the frame body 7 is in the upright state. Therefore,
Even if the car goes out of control due to a driver's operational error,
The car is prevented from running by the car stop fence 8, and the car collides with the landing door 3, and this impact causes the landing door 3 to
It is possible to avoid the worst case scenario of the machine coming off and falling into the hoistway.

Next, when the landing door 3 is open, the car stop fence 8
is rotated in the direction of arrow A by the drive device 9, and when it becomes horizontal, it is stored in the storage groove 10 provided in the frame body 7. At the same time, a GO sign is displayed on indicator 5, and the driver can proceed according to the instructions. The small gear motor 12 is started at the same time as the door opening/closing command for the hall door 3, and its stop is made by turning off the limit switches 15a and 15b.
It is carried out by.

According to the above-mentioned embodiment, when the landing door 3 is closed, the car stop fence 8 provided on the frame body 7 stands up, making it possible to prevent intrusion of automobiles and the like. Moreover, since this frame body 7 is simply placed on the landing floor 6 in front of the landing door 3 and fixed with anchor bolts 16, it is not only extremely easy to apply to already delivered products, but also the work can be done in an extremely short time. I can do it. Moreover, it can be easily attached to a boarding floor 6 having a thin thickness.

[Effect of idea]

According to this invention, the frame body is simply placed on the landing floor in front of the landing door and fixed with anchor bolts, so it is not only extremely easy to apply to already delivered products, but also the work can be done in an extremely short time. I can do it. In addition, it is possible to obtain remarkable practical effects such as being able to be easily installed even on those with thin landing floors.
