Abstract

PURPOSE:To secure the safety to a wrong-minded user who tries to run a basket for man transfer by providing an operation means which enables automatic operation by a basket destination registration device in a basket only when an automobile detection signal is generated. CONSTITUTION:In case a user tries to run a basket to a desired floor for other purposes than transfer of an automobile, an automobile detection signal outputting action is not performed by an automobile detection device 1 because an automobile is not carried on the basket, and an automobile detection signal contact 2 is opened, so a basket destination registration circuit 3 is no electrically connected to power sources P, N. If the user operates a basket destination registration button, therefore, a basket destination registration action is not performed by the basket destination registration circuit 3, and the basket cannot run, thereby a serious accident which may occur when the basket is used for other purposes than transfer of automobiles, that is man transfer, can be prevented securely.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a safety device for operating an elevator system for a motor vehicle.

[Conventional technology]

Elevator equipment for automobiles, for example,
As shown in Publication No. 47951,
The user travels to the desired floor while riding in the car (because the structure is such that there is generally no door on the car side, and the car is within a specified range within the car). The structure is such that a photoelectric device is arranged to detect something, and if the photoelectric device is activated, the car cannot be driven, or the car is equipped with a structure that prevents the car from protruding from the passenger compartment on the floor. In addition, it has a vehicle stopper device at a predetermined position.

[Problem to be solved by the invention]

Now, with the above-mentioned structure of the automobile elevator system, there is no safety problem if the user uses it for its intended purpose. It is sometimes used for transportation. As mentioned above, this type of elevator equipment does not have a door on the car side, so if it is used for transporting people, there is a possibility that the car may accidentally fall into the hoistway, or the car may fall into the hoistway. There is a risk of serious accidents such as being caught between the shaft and the hoistway.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and its object is to provide an elevator system for automobiles that cannot be used for the purpose of transporting personnel.

[Means to solve the problem]

In order to achieve the above object, the elevator device for a car of the present invention includes a car detection device that detects when a car is stored in a car, and a car detection signal that is emitted from the car detection device. The car is characterized by having an operation means that enables automatic operation using a car destination floor registration device provided in the car.

[For production]

In the present invention, the car cannot be used for purposes other than transporting automobiles, so it is an excellent automobile vehicle that can ensure safety for unsuitable passengers who try to use the car for the purpose of transporting personnel. This has the effect of realizing an elevator system.

〔Example〕 Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a circuit diagram showing the main parts of an embodiment of the present invention. In the figure, P and N are control power supplies, and 1 is an output when it is detected that a car has entered the car. A vehicle detection device that emits a signal, for example, a load detection type vehicle detection device that is configured to output an output when the payload in the car reaches a predetermined value, or and a photoelectric vehicle detection device configured to determine that a vehicle is parked when both the photoelectric beams of the phototubes disposed at the rear are blocked, and 2 is configured in this way. Automobile detection device 1
3 is a car destination floor registration circuit that allows the car to travel to a desired floor by operating a car destination floor registration button located on a driving panel provided in the car; 4 is a car destination floor registration circuit; The vehicle detection device 1 is connected between the control power sources P and N by a maintenance switch provided in the above-mentioned driving panel and used during maintenance. A series circuit of the vehicle detection signal contact 2 and the car destination floor registration circuit 3 is connected between control power supplies P and N, and a maintenance switch 4 is connected in parallel with the vehicle detection signal contact 2.

Next, the operation of this embodiment configured as described above will be explained.

Now, when a car enters the car, the car detection device 1 detects this and closes the car detection signal contact 2, which is its output signal, to control the car destination floor registration circuit 3. P
, N are electrically connected.

At this time, when the driver of the car operates the car destination floor registration button corresponding to the desired floor of the car turntable, the car destination floor registration circuit 3 is electrically connected to the control power supplies P and N. Therefore, the car destination floor corresponding to the desired floor is registered using a known circuit, and the car travels toward that floor based on the known elevator operation circuit, thereby achieving the driver's objective. be done.

Next, if you ride the car for any purpose other than transporting a car,
A case will be explained in which an attempt is made to operate this car to a desired floor.

Since there is no car in the car, the car detection device 1 does not output the car detection signal, so the car detection signal contact 2 is in an open state, and the car is not in the car. The destination floor registration circuit 3 is not electrically connected to the control power supplies P and N. So now,
Even if this user operates the car destination floor registration button, the car destination floor registration circuit 3 cannot register the car destination floor, so the car cannot run. If the elevator is used exclusively for transporting cars and does not have a door, the car may not be used for purposes other than transporting cars.
That is, serious accidents such as passengers coming into contact with the hoistway wall or being caught between the car and the hoistway wall, which may occur when the car is used for the purpose of transporting personnel, can be reliably prevented.

On the other hand, in this embodiment, when the maintenance staff needs to check the operation status of the elevator during periodic inspection of the elevator, etc., the above-mentioned configuration allows the maintenance staff to check the operation status of the elevator. However, there is an inconvenience that the car cannot be run unless it is in stock.
However, in such a case, when the maintenance switch 4 provided in the operation panel is switched to the maintenance side, the maintenance switch 4 is closed and the car destination floor registration circuit 3 is switched to the control power HP.
. The destination floor registration circuit 3 can perform a call registration operation. Therefore, even if the car is not stored in the car, the operation of the car destination floor registration circuit 3 etc. and other harmful functions can be checked in the same way as when the car is stored in the car. Confirmation can be easily and conveniently performed. In addition, in such a case,
The maintenance personnel who perform this work are familiar with elevators, so there is no problem or danger.

As explained above, in this embodiment, since the passenger car cannot normally be operated for purposes other than automobile transportation, it is possible to ensure the safety of users, and also to avoid hindrance to maintenance work. This has the effect that it is possible to realize an elevator system for automobiles.

〔Effect of the invention〕

As explained above, the present invention is configured such that the passenger car cannot be used for any purpose other than transporting automobiles under normal circumstances, and therefore, there is no advantageous use of the passenger car for the purpose of transporting personnel. It is possible to ensure the safety of people.
