Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator suitable for a building, such as a special hotel, which does not like passengers.

[0002]

[Prior art]

 Conventionally, as an elevator for a special hotel of this kind, as disclosed in JP-A-1-122884, an alarm device is installed in each guest room so that the elevator can be used by other passengers by letting them know the usage status of the elevator. If they are told that they are waiting in the guest room, they prevent customers from meeting each other in the elevator hall.

[0003]

[Problems to be solved by the device]

 The elevator disclosed in the related art is provided in all guest rooms in addition to the elevator main body inspection during the regular inspection of the elevator to install an alarm device in each guest room. There was also the problem that the passenger compartment could not be used when inspecting the elevator because it was necessary to inspect the alarm device. In addition, such an elevator in which all the guest rooms are provided with the alarm device inevitably requires a high installation cost.

An object of the present invention is to provide an elevator capable of preventing elevator users from meeting each other in the hall without providing an alarm device in the passenger compartment.

[0005]

[Means for Solving the Problems]

 The object of the present invention is to provide as many destination floor call buttons as there are stop floors in the car, and hall call buttons at each stop floor to electrically register that each of the buttons has been operated. In an elevator equipped with an operation circuit that responds sequentially, two sets of car doors are provided in the car, two sets of hatch doors are also provided at each stop floor, and the hall is provided only near one of the hatch doors. A call button is provided, and when it is detected that the hall call registration floor and the destination floor call registration floor are the same floor, the opening and closing of the door on the side where the hall call button is provided is restricted for a predetermined time. This is achieved by providing a control circuit.

[0006]

[Action]

 According to the above configuration, a door for getting into the car from the hall and a door for getting off from the car to the hall are provided respectively, and when a hall call and a destination floor call on the same floor are registered, The control circuit limits the opening and closing of the door on the side where the hall call button is installed so that passengers waiting in the hall after loading the passenger in the car can be placed in the car until the opening and closing of the opposite door is completed. They don't meet each other in the elevator hall.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of the present invention. A car 1 is provided with a door 2 on the entrance side and a door 4 on the exit side. A side hatch door 3 and an exit side hatch door 5 are provided. FIG. 2 is a front view of the elevator hall 6 on the entrance side, and is provided with a car position display device 8 having a hall call button. Around the hatch door 3 on the entrance side, a display plate 9 indicating that the door is the entrance door is provided at a position where it is easily noticed by the user. FIG. 3 is a front view of the exit side elevator hall 7, and there is a display board 10 indicating that this door is the exit near the exit side hatch door 5 and that the passenger cannot enter the car from here. It is provided. FIG. 4 shows an elevator door control circuit according to the present embodiment. Da ₁ and Da ₂ are the elevators ₁ and ₂ since the operation panel in the car was operated and the first floor destination floor was called and registered. It is a normally open contact of a relay (not shown) that is excited until the car door 5 on the exit side is opened and closed when the car arrives at the floor. Ea ₁ and E a ₂ are operated by the hall call button provided in the elevator hall on the first floor, and the elevator arrives on the first floor when the hall call registration on the first floor is performed and the car door on the entrance side 2 It is a normally open contact of a relay (not shown) that is excited until the opening and closing of is completed. A is a relay that requires opening and closing of each door on the same floor, in particular, a relay for temporarily restricting opening and closing of the door on the entrance side, and Ab is a normally closed contact. B is an opening / closing command relay for the car door 4 on the exit side, and Bb is its normally closed contact. C is an opening / closing command relay for the car door 2 on the entrance side, and Cb is its normally closed contact. F ₁ is a circuit for controlling the door on the first floor, and circuits F ₂ ... Fn having the same structure are provided for each floor. P and N indicate power sources.

Next, the operation of this embodiment will be described. Now, suppose that a passenger gets into the car 1 on the other floor and operates the destination floor call button on the first floor to register the call. Corresponding to the destination floor call registration on the first floor, the normally open contacts Da ₁ and Da ₂ are closed. At the same time, when the passenger in the elevator hall 6 on the entrance side on the first floor operates the hall call button to register for the hall call on the first floor, the normally open contacts Ea ₁ and Ea ₂ correspond to the hall call registration. Closes. When there are passengers getting off from the car 1 and passengers getting on the same floor, even if the operation of either button is early, the limiting relay A on the door on the entrance side will cause the P-Da ₁ -E a ₁ -A because it is excited by the configuration of the closed circuit -N, since the normally open contact Da ₁ opens normally closed contact Ab, closing of Da _2, Ea _1, Ea ₂ continues until closing termination of each door, P- A closed circuit of Da ₂ -Cb-B-N is configured to excite the exit door opening / closing command relay B, and when the car reaches the first floor, the exit side car door 4 Is opened and closed first, and the hatch door 5 is opened and closed by engaging with the car door 4, so that the passenger inside the car 1 gets out. When the opening and closing of the car door 4 is completed, the normally open contacts Da ₁ and Da ₂ are opened, the limiting relay A of the door on the entrance side is demagnetized, and the normally closed contact Ab is closed. At the same time, the exit door opening / closing command relay B is also demagnetized, so that the normally closed contact Bb is also closed. More This is configuration closed circuit _{P-Ea 2 -Bb-Ab-} C-N, opens Nokuchi side door command relay C is excited in Nokuchi side door, the basket not already a customer Passengers waiting in the elevator hall 6 at the entrance can use the elevator. When the opening and closing of the door on the passenger side is completed, the normally open contacts Ea ₁ and Ea ₂ are opened, and the operation of the control circuit F ₁ is completed. The elevator according to the present embodiment uses an operation system in which one set of passengers performs a dedicated operation that does not respond to hall calls on other floors while the elevator is in use. The description will be omitted because it can be implemented by using any known dedicated operation method. As described above, according to the present embodiment, an elevator user can move to another floor by using the elevator without meeting another user.

[0009]

[Effect of device]

 According to the present invention, two doors are provided in the car to prevent the control circuit from opening the respective doors at the same time, and after the passengers in the car have been dropped out, the user waiting in the elevator hall is placed in the car. Since the two doors are controlled to open and close so that the passengers do not face each other, the privacy of the user can be protected.
