- the footboard 5 can be turned around an axis parallel to a width direction of the car 1.
- Aplurality of springs 7 are interposed between an upper surface of the car chamber 2 and a lower surface of the footboard 5.
- the footboard 5 is held at a normal position by the springs 7 when a maintenance operator is not on the footboard 5.
- the springs 7 are compressed, and the footboard 5 is turned in such a direction that an end thereof on the landing doorway 4 side (front end thereof) is depressed. As a result, the footboard 5 is displaced to a weighting position.
- a front end surface of the footboard 5 is provided with a protrudable/retractable latch 8.
- a latch engagement member 9, with which the latch 8 is engaged when the footboard 5 is displaced to the weighting position, is fixed on the car chamber 2.
- a release handle 11 serving as a release manipulation portion for releasing the holding of the footboard 5 at the weighting position by the holding mechanism 10 is provided on the footboard 5 in the vicinity of the front end thereof.
- the release handle 11 Bymanipulating the release handle 11 in a rotating manner in the direction of an arrow A of Fig. 1 , the latch 8 is retracted to the footboard 5 side and thereby disengaged from the latch engagement member 9.

- a control device 13 controls the operation of the car 1 based on a manipulation state of the detection switch 12.
- Fig. 2 is a circuit diagram showing an example of a circuitry of the control device 13 of Fig. 1 .
- the detection switch 12 is connected in series to a power supply switch 14 for making a changeover between an operable state and an inoperable state.
- the detection switch 12 is connected to an automatic operation side thereof when the footboard 5 is at the normal position, and to a maintenance operation side thereof when the footboard 5 is at the weighting position.
- An operation mode changeover switch 15 for making a changeover in operation mode between an automatic operation mode and a maintenance operation mode is connected in series to the detection switch 12.
- the operationmode changeover switch 15, which is provided on the car 1, is manipulated by the maintenance operator on the car 1.
- a normal operation command issuing relay 16 is connected to a terminal of the operation mode changeover switch 15 on an automatic operation side thereof.
- An UP operation command issuing relay 18 and a DOWN operation command issuing relay 19 are connected in parallel to a terminal of the operation mode changeover switch 15 on a maintenance operation side thereof via a maintenance running switch 17.
- the detection switch 12 is normally connected to the automatic operation side thereof. Accordingly, when the operation mode changeover switch 15 is connected to the automatic operation side thereof while a contact of the power supply switch 14 is closed, the normal operation command issuing relay 16 is energized, so the operation mode is set to the automatic operation mode. In the automatic operation mode, the car 1 is automatically operated in response to calls from landings and calls from within the car 1.
- the operation mode is changed over to the maintenance operationmode.
- the maintenance operation mode callsfrom within the car 1 and calls from the landings are invalidated, and the maintenance operator manipulates the maintenance running switch 17 to raise/lower the car 1 at low speed.

Therefore, even in the unlikely event that the maintenance operator closes the landing doors without manipulating the operation mode changeover switch 15 and moves out of a region on the car 1 where the footboard 5 is provided, the car 1 is not automatically operated. That is, the car 1 can be more reliably prevented from being automatically operated with the maintenance operator thereon.
- the footboard 5 is mechanically held at the weighting position by the holding mechanism 10. Therefore, even if the maintenance operator carelessly forgets to manipulate the power supply switch 14 or the operation mode changeover switch 15 by an oversight and steps onto the car 1 during the repair of a malfunction involving a blackout, the detection switch 12 is manipulated by the footboard 5. Therefore, the car 1 is prevented from being operated.
- the release handle 11 is provided on the footboard 5 in the vicinity of the front end thereof, so the release handle 11 can be manipulated after the maintenance operator has moved onto the landing.
- the operation mode changeover switch 15 is provided on the car 1 separately from the detection switch 12 so as to permit maintenance operation only when the detection switch 12 is actuated and the operation mode changeover switch 15 is changed over to the maintenance operation side thereof, and to permit automatic operation only when the detection switch 12 is released and the operation mode changeover switch 15 is changed over to the automatic operation side thereof. Therefore, an erroneous changeover in operation mode can be prevented more reliably.

-
Fig. 1 is a perspective view showing a car of an elevator apparatus according toEmbodiment 1 of the present invention. Referring toFig. 1 , acar 1 has a car frame (not shown) suspended within a hoistway, and acar chamber 2 supported by the car frame. A front surface of thecar chamber 2 is provided with acar doorway 2a. Thecar doorway 2a is opened/closed by a pair ofcar doors 3. Alanding doorway 4 is provided at a landing of each stop floor. Thelanding doorway 4 is opened/closed by a pair of landing doors (not shown) . - A
footboard 5 is provided on thecar chamber 2 in the vicinity of an edge thereof on thelanding doorway 4 side. An end of thefootboard 5 on the other side of the landing doorway 4 (rear end of the footboard 5) is connected to an upper portion of thecar chamber 2 by means of a plurality ofhinges 6. Thus, thefootboard 5 can be turned around an axis parallel to a width direction of thecar 1. - Aplurality of
springs 7 are interposed between an upper surface of thecar chamber 2 and a lower surface of thefootboard 5. Thefootboard 5 is held at a normal position by thesprings 7 when a maintenance operator is not on thefootboard 5. When the maintenance operator gets on thefootboard 5 to add a weight thereto, thesprings 7 are compressed, and thefootboard 5 is turned in such a direction that an end thereof on thelanding doorway 4 side (front end thereof) is depressed. As a result, thefootboard 5 is displaced to a weighting position. - A front end surface of the
footboard 5 is provided with a protrudable/retractable latch 8. Alatch engagement member 9, with which thelatch 8 is engaged when thefootboard 5 is displaced to the weighting position, is fixed on thecar chamber 2. Aholding mechanism 10, which is composed of thelatch 8 and thelatch engagement member 9, mechanically holds thefootboard 5 displaced to the weighting position at the weighting position. - A
release handle 11 serving as a release manipulation portion for releasing the holding of thefootboard 5 at the weighting position by theholding mechanism 10 is provided on thefootboard 5 in the vicinity of the front end thereof. Bymanipulating therelease handle 11 in a rotating manner in the direction of an arrow A ofFig. 1 , thelatch 8 is retracted to thefootboard 5 side and thereby disengaged from thelatch engagement member 9. Thus, the front end of thefootboard 5 is pushed up by thesprings 7, so thefootboard 5 is returned to the normal position. - A
detection switch 12 for detecting a displacement state of thefootboard 5 is provided on thecar chamber 2. Thedetection switch 12 is mechanically manipulated through displacement of thefootboard 5 to the weighting position. Acontrol device 13 controls the operation of thecar 1 based on a manipulation state of thedetection switch 12. -
Fig. 2 is a circuit diagram showing an example of a circuitry of thecontrol device 13 ofFig. 1 . Thedetection switch 12 is connected in series to apower supply switch 14 for making a changeover between an operable state and an inoperable state. Thedetection switch 12 is connected to an automatic operation side thereof when thefootboard 5 is at the normal position, and to a maintenance operation side thereof when thefootboard 5 is at the weighting position. - An operation
mode changeover switch 15 for making a changeover in operation mode between an automatic operation mode and a maintenance operation mode is connected in series to thedetection switch 12. Theoperationmode changeover switch 15, which is provided on thecar 1, is manipulated by the maintenance operator on thecar 1. - A normal operation
command issuing relay 16 is connected to a terminal of the operationmode changeover switch 15 on an automatic operation side thereof. An UP operationcommand issuing relay 18 and a DOWN operationcommand issuing relay 19 are connected in parallel to a terminal of the operationmode changeover switch 15 on a maintenance operation side thereof via amaintenance running switch 17. - As described above, the
detection switch 12 is normally connected to the automatic operation side thereof. Accordingly, when the operationmode changeover switch 15 is connected to the automatic operation side thereof while a contact of thepower supply switch 14 is closed, the normal operationcommand issuing relay 16 is energized, so the operation mode is set to the automatic operation mode. In the automatic operation mode, thecar 1 is automatically operated in response to calls from landings and calls from within thecar 1. - In this state, when the
detection switch 12 is changed over to the maintenance operation side thereof and the operationmode changeover switch 15 is changed over to the maintenance operation side thereof, the operation mode is changed over to the maintenance operationmode. In the maintenance operation mode,callsfrom within thecar 1 and calls from the landings are invalidated, and the maintenance operator manipulates themaintenance running switch 17 to raise/lower thecar 1 at low speed. - In the elevator apparatus constructed as described above, the
footboard 5 displaced to the weighting position is mechanically held at the weighting position by theholding mechanism 10 until therelease handle 11 is manipulated. Therefore, even in the unlikely event that the maintenance operator closes the landing doors without manipulating the operationmode changeover switch 15 and moves out of a region on thecar 1 where thefootboard 5 is provided, thecar 1 is not automatically operated. That is, thecar 1 can be more reliably prevented from being automatically operated with the maintenance operator thereon. - The
footboard 5 is mechanically held at the weighting position by theholding mechanism 10. Therefore, even if the maintenance operator carelessly forgets to manipulate thepower supply switch 14 or the operationmode changeover switch 15 by an oversight and steps onto thecar 1 during the repair of a malfunction involving a blackout, thedetection switch 12 is manipulated by thefootboard 5. Therefore, thecar 1 is prevented from being operated. - Further, the
release handle 11 is provided on thefootboard 5 in the vicinity of the front end thereof, so therelease handle 11 can be manipulated after the maintenance operator has moved onto the landing.
Still further, the operationmode changeover switch 15 is provided on thecar 1 separately from thedetection switch 12 so as to permit maintenance operation only when thedetection switch 12 is actuated and the operationmode changeover switch 15 is changed over to the maintenance operation side thereof, and to permit automatic operation only when thedetection switch 12 is released and the operationmode changeover switch 15 is changed over to the automatic operation side thereof. Therefore, an erroneous changeover in operation mode can be prevented more reliably. - The release handle 11 and the
latch 8 may be integrated with each other . In this case, a commercial door component having a handle integrated with a latch can be employed as an example. As a result, a cost reduction can be achieved.
In the foregoing example, thelatch 8 and thelatch engagement member 9 are provided on thefootboard 5 and thecar chamber 2, respectively. On the contrary, however, thelatch engagement member 9 and thelatch 8 may be provided on thefootboard 5 and thecar chamber 2, respectively. - Reference will be made next to
Fig. 3. Fig. 3 is a perspective view showing a car of an elevator apparatus according toEmbodiment 2 of the present invention. Although omitted inFig. 1 for the sake of simplicity, a structure for supporting thecar doors 3 is also illustrated inFig. 3 . Referring toFig. 3 , arelease button 21 serving as a release manipulation portion for releasing the holding of thefootboard 5 at the weighting position by the holdingmechanism 10 is provided on an end surface of thefootboard 5 on thelanding doorway 4 side thereof (front end surface of the footboard 5) . By manipulating therelease button 21 in a pressing manner in the direction of an arrow B ofFig. 3 , thelatch 8 is retracted to thefootboard 5 side and thereby disengaged from thelatch engagement member 9. Thus, the front end of thefootboard 5 is pushed up by the springs 7 (Fig. 1 ), so thefootboard 5 is returned to the normal position. - A
girder 22 for supporting thecar doors 3, which has an inverse-L-shaped cross-section, is fixed to an upper portion of the front surface of thecar chamber 2. Thegirder 22 is provided with anopening portion 22a for exposing therelease button 21 to the landing side. Therelease button 21 is manipulated through theopening portion 22a from the landing side. - A
door rail 23 for guiding the opening/closing movements of thecar doors 3 is fixed to thegirder 22. Each of thecar doors 3 has adoor panel 24, adoor hanger 25 fixed to an upper portion of thedoor panel 24, and a pair ofhanger rollers 26 provided on thedoor hanger 25 to be rolled on thedoor rail 23. Thecar doors 3 are suspended from thedoor rail 23.Embodiment 2 of the present invention is identical toEmbodiment 1 of the present invention in other constructional details. - In the elevator apparatus constructed as described above, the
release button 21 is provided on the front end surface of thefootboard 5. Therefore, therelease button 21 can be more reliably manipulated from each of the landings.
Thegirder 22 is provided with theopening portion 22a to allow therelease button 21 to be manipulated through theopening portion 22a. Therefore, therelease button 21 can be more reliably manipulated from each of the landings. - The
release button 21 may be provided on thelanding doorway 4 side with respect to thegirder 22. Thus, therelease button 21 is not easily manipulated on thecar 1. As a result, therelease button 21 can be more reliably manipulated from each of the landings. - Reference will be made next to
Fig. 4. Fig. 4 is a circuit diagram showing an example of a circuitry of a control device of an elevator apparatus according toEmbodiment 3 of the present invention. In this example, thedetection switch 12 serves also as the operationmode changeover switch 15. That is, when thefootboard 5 is displaced to the weighting position through addition of a weight, thedetection switch 12 is changed over to the maintenance operation side thereof, so the operation mode is changed over to the maintenance operation mode. When thefootboard 5 is returned to the normal position, thedetection switch 12 is returned to the automatic operation side thereof, so the operation mode is changed over to the automatic operation mode.Embodiment 3 of the present invention is identical toEmbodiment - In the elevator apparatus constructed as described above, the operation mode is changed over to the maintenance operation mode when the
footboard 5 is displaced to the weighting position, and returned to the automatic operation mode when thefootboard 5 is returned to the normal position. Therefore, the operationmode changeover switch 15 is not required. As a result, a cost reduction can be achieved, and an erroneous changeover in operation mode can be prevented from being made due to a failure to manipulate the operationmode changeover switch 15 or an erroneous manipulation thereof. - In each of the foregoing examples, the release handle 11 or the
release button 21 is illustrated as the release manipulation portion. However, the release manipulation portion should not be limited in shape or mechanism thereto, and may be realized as, for example, a knob. The release manipulation portion is not necessarily manipulated in a rotating manner or a pressing manner, and may be manipulated in a pulling manner.
In each of the foregoing examples, thefootboard 5 is returned to the normal position due to restoring forces of thesprings 7. However, an elastic body such as rubber or the like may be employed as an example of restoration means for restoring thefootboard 5 to the normal position.
Further, thefootboard 5 is turned to be displaced between the normal position and the weighting position in each of the foregoing examples. However, thefootboard 5 may be designed, for example, to be displaced vertically as a whole.
Still further, thesingle footboard 5 is employed in each of the foregoing examples. However, thefootboard 5 may be divided into a plurality of boards.
Although thesingle detection switch 12 is employed in each of the foregoing examples, it is also appropriate to employ a plurality of detection switches and disable automatic operation when displacement of thefootboard 5 to the weighting position is detected by any one of the detection switches.
