摘要： PURPOSE:To prevent malfunction at overload at detecting the load once by obstructing start of an elevator until the load is removed through self-holding of a detecting relay, independent of ON-OFF of contacts in an abnormal using condition. CONSTITUTION:When overload is detected, an overload detecting device WD110 makes running command relays 11A, 12A OFF with a b-contact. When a door is not closed. on the a-contact side of the overload detecting device WD110 a buzzer BZ is rung to raise an alarm, the buzzer is not stopped to ring until passengers get out of a cage to dissolve overriding, and then returned to initial condition. When the door is closed neglecting the alarm, a relay 65WA is self- held with a contact 65WA3, and the buzzer BZ is continued to ring with a contact 65WA2. At this time, even if a person jumps or goes wild in the cage, the running command circuit is put OFF with a contact 65WA1 not to enable to run due to self holding of the relay 65WA. When the door is opened and the person gets out of the cage, a relay 40, the overload detecting device WD110, and the relay 65WA are put OFF, and the normal condition is returned.

摘要： PURPOSE:To use an elevator at rest by a specified person only and know that use demand is given to the elevator at rest by providing a a parking switch and an alarm guide device of elevator in a building manager room. CONSTITUTION:When an elevator is at rest by a parking switch 5, a landing button 1 on a floor is operated and its signal is input into an MPU 2a through an input device 26. The MPU 2a judges on which floor the landing button is operated and compares the operating procedure of it with that set beforehand in a RAM 2e. If they are identical to each other, a landing call is registered and a rest release command is emitted to an elevator device 3 through an output device 2c. When a user presses a car call button 4 in a car, the elevator is operated and, when it arrives at a destination floor and use is completed, a control device 2 returns it again to the rest condition. Also if the landing button 1 is operated at rest condition, the control device 2 also outputs a landing call signal to an alarm guide device 6.

摘要： PURPOSE:To detect a passenger in a cage and emit an alarm in case an in-cage destination button is not operated within the fixed time so as to prevent an accident by providing a device for detecting the existence of the passenger in the cage by the action sequence of a hall door closure detector and a cage door closure detector. CONSTITUTION:A hall door and a cage door are formed to be opened manually, so that a passenger on the hall side first opens a hall door 3 manually at the time of getting into a cage 1 and then opens a cage door 4 to enter the cage 1. The passenger who gets into the cage closes the hall door manually. At this time, a hall door closure detecting switch 5 is placed in the closed state. A cage door closure detecting switch 6 is then closed by closing the cage door 4 manually, and by this action sequence, the existence of the passenger in the cage is judged. In case destination call button 2 in the cage is not operated even after the lapse of the fixed time limit in spite of the passenger existing in the cage, an alarm device 7 is actuated to give a warning.

摘要： PURPOSE:To keep off any continuous operation due to mischief by stopping an elevator once at the floor as long as a specified time interval with a timer device unless a fact that a door is opened is detected after the elevator has finished its travel operation. CONSTITUTION:When an elevator cage travels and arrives at the destination floor, a stop command contact point S is opened whereby an up operating relay 1 is demagnetized and it comes to a stop, and a travel operation detecting relay 4 is also demagnetized. At this time, if a floor door or a cage door is opened, a door-shut detecting relay 3 is demagnetized, and if a door-open detecting relay 5 is once demagnetized after travel operation completion, it is so judged that boarding or alighting action by people has been carried out. On the other hand, when the door is not opened, the relay 5 is in a state of being excited whereby each making circuit of both up and down operation relays 1, 2 is not formed, so that a timer relay 6 is operated, and the elevator cage is stopped at the floor as long as the specified time. Thus, such tampering operation as operating the elevator continuously without entailing any door-open action after the travel operation completion is thus preventable.

摘要： PROBLEM TO BE SOLVED: To give a hint for operating a door to open to a child or the like left in a car so as to easily get out outside the car by lighting the lamp of a destination button in car, when an elevator is in the stopped state on a coming back floor in the case of the elevator being in the automatic stop state by a control operation command and the like. SOLUTION: An elevator is operated to return to a comming back floor by a control operation command or a parking operation command, the door is opened after arrival at the comming back floor, and lighting in car is put out into an operation stooped state. A series of these operations are carried out by an elevator control device 5, and when a stop operation detecting means 5A detects the operation stop state, a lamp of a destination button 4 (4a-4f) in car is lighted through an operation disc control command means 5B and an operation board control device 7 in car, and simultaneously the door is closed through a door control command means 5C and a door control device 6. When a person left in the car in this state touches the destination button 4 is car in this state, the door is opened.

摘要： PROBLEM TO BE SOLVED: To secure door opening time while passengers get on and off an elevator, if there is a wheelchaired passenger and if the percentage of passengers inside the elevator car is high and to allow the passengers to smoothly get on and off the car. SOLUTION: An elevator car 1 is provided with in-car load detecting devices 2a, 2b mounted on the underside of the car, their data being sampled into an in-car load computing means 5C located inside an elevator control device 5, while the anticipated time required to get on or off the car is computed by an anticipated landing time computing means 5D. Based on the computation result, door opening time is output to a door control means 5F, and a door control device 6 is driven.

摘要： PURPOSE:To eliminate passenger's uncomfortable feelings by turning off a lamp which judges an abnormality based on a signal outputted from illumination abnormality detectors in a car of an elevator. CONSTITUTION:Illumination abnormality detectors 4a-4d in a car detect a change of luminous flux measured by photometers 3a-3d and transmit it as a lamp abnormality signal to an elevator controller 5. When a lamp 2a flickers, a lamp abnormality signal is outputted from the illumination abnormality detector 4a in the car with a contact 4aa in a closed condition to energize a lamp abnormality detection relay 9A coil. For this reason, a normally-closed contact 9Ab is opened and the lamp 2a is turned off. On the other hand, as for the energized condition of the lamp abnormality detection relay 9A coil, a normally-open contact 9Aa which is a self-hold contact is closed to form a self-hold circuit. The self-hold circuit is opened by operating a lamp exchange check button MA to release the lamp abnormality detection relay 9A coil.

摘要： PROBLEM TO BE SOLVED: To attain a passenger's getting on/off easily and suppress degradation of operational efficiency. SOLUTION: An operating signal is inputted into an in-car car-call registering device switching signal detecting means 4A in an elevator controller 4. An in-car load detecting device 3 is fitted, and in-car load is inputted into an in-car load calculation means 4B in the elevator controller 4. Whether the in-car load is in excess of a prescribed value or not is determined and inputted into an in-car car-call registering device switching means 4C. A detected signal from the switching signal detecting means 4A is also inputted into the in-car car-call registering device switching means 4C. Based on these two signals, an in-car car-call registering device switching command is set to switch in-car car-call registering devices 2a, 2b. This device is constituted so that a getting-in-car device may be operated as a result of a getting-in-car guide control means 4D being inputted and a getting-in-car guide command being set.
