JP-A-7-267564

  In the above-described wheelchair escalator operation guidance device, the operation devices are sequentially turned on in accordance with the wheelchair escalator operation procedure. In general, escalators are exclusively used for ascending or descending operation and are used only in one-way operation. Therefore, the escalator must be stopped temporarily during ascending operation and switched to descending operation, or temporarily stopped during descending operation and switched to ascending operation. There is no. Therefore, in the conventional operation guidance device, it is sufficient to turn on the operation device according to the operation procedure, and the pedestal is stopped in the middle of the ascending operation and lowered, for example, by the helper's judgment as in the step elimination device. No consideration is given to cases such as switching to driving or stopping the driving in the middle or switching the driving direction in the middle, such as stopping the bridge that advances from the pedestal during the advancing operation and switching to the reverse operation. There was a problem.

  In the conventional operation guidance device, since the escalator is used only for one-way operation only for ascending or descending operation, there is only a start button at the start of operation, and the ascending button and the descending button like the step elimination device In addition, it is not assumed that a plurality of operation buttons can be operated in one operation such as an advance button and a reverse button, and no consideration is given to erroneous operation notification means when a plurality of buttons are operated by mistake. It wasn't.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide an operation guide device for a step eliminating device that can perform operation guidance corresponding to an operation unique to the step eliminating device.

In order to achieve this object, the present invention includes a pedestal that is installed in front of a step having a step and moves up and down by a lifting operation, and a bridge that is installed in the pedestal and moves forward and backward by advancing and retreating operation. In such a state, the bridge is advanced toward the portion having the step, thereby being provided in the step eliminating device that enables movement of the moving body mounted on the pedestal,

A first detection switch; a second detection switch provided on the pedestal for detecting that the bridge has advanced to the uppermost floor surface of the step; and the ascending button or descending during the ascending / descending operation of the pedestal When the operation of the button is stopped and the pedestal is stopped, the operation of raising and lowering the pedestal is both notified and requesting the raising / lowering operation, When the operation of the advance button or the reverse button is stopped during the forward / backward operation of the bridge and the bridge is stopped, the advance / retreat operation is notified by informing that both the advance operation and reverse operation of the bridge are possible. Operation request notifying means for requesting a driving operation, the pedestal is moved up and down by continuing to operate the ascending button and the descending button, and the advance button and the retreat button are operated continuously to advance and retract the bridge. When the operation and the ascending button, the descending button, the advance button and the backward button are interrupted, the operation based on the operation is stopped, and by continuing to operate the ascending button, When the pedestal rises to the same height as the top of the step, the first detection switch operates The pedestal automatically stops, the operation request notification means informs that the advance button should be operated, and by continuing to operate the advance button, the bridge reaches the uppermost floor of the step. When the vehicle advances, the second detection switch operates to automatically stop the bridge, and the passage permission light provided on the operation panel is turned on to notify that the movable body can be moved. It is characterized by that.

  Further, in the present invention according to the present invention, when both the ascending button and the descending button are erroneously operated during the raising / lowering operation of the pedestal, the pedestal is stopped and the raising / lowering operation of the pedestal is invalidated. When both the advance button and the reverse button are erroneously operated during the forward / backward operation of the bridge, the bridge is stopped and the advance / retreat operation of the bridge is invalidated. It is characterized by having an erroneous operation notification means.

The changeover switch and operation buttons provided on the operation panel 5 are not operated by the wheelchair user 3 but are mainly operated by the assistant 3a.

  The indicator lights 5b1, 5c1, 5d1, and 5e1 that are turned on in response to the operations of the ascending button 5b, the descending button 5c, the advance button 5d, and the backward button 5e described above constitute operation procedure notification means.

  In the present embodiment, in particular, when the control device 6 stops the pedestal 1 by stopping the operation of the ascending button 5b or the descending button 5c during the ascending / descending operation of the pedestal 1, both the ascending button 5b and the descending button 5c are operated. By turning on the indicator lamps 5b1 and 5c1, it is notified that either the ascending operation or the descending operation of the pedestal 1 is possible, and the ascending / descending operation operation is requested. When the operation of the button 5e is stopped and the bridge 2 is stopped, both the advance operation and the reverse operation of the bridge 2 are performed by turning on the indicator lights 5d1 and 5e1 of both the advance button 5d and the reverse button 5e. Operation request notifying means for notifying that it is possible and requesting forward / backward driving operation is provided.

  Further, for example, when both the ascending button 5b and the descending button 5c are erroneously operated during the raising / lowering operation of the pedestal 1, the control device 6 stops the pedestal 1 and both the ascending button 5b and the descending button 5c. When the indicator lights 5b1 and 5c1 are turned off to notify that the ascending / descending operation of the pedestal 1 is invalid, and both the advance button 5d and the reverse button 5e are erroneously operated during the forward / backward operation of the bridge 2. In addition, there is also provided an erroneous operation notifying means for notifying that the bridge 2 is stopped and the indicator lights 5d1 and 5e1 of both the advance button 5d and the reverse button 5e are turned off to invalidate the advance / retreat operation of the bridge 2.

  3 to 6 are flowcharts showing processing operations performed in this embodiment. Hereinafter, the specific processing of the present embodiment will be described with reference to FIGS.

  First, a normal operation button indicator lighting procedure when moving the wheelchair user 3 mounted on the pedestal 1 of the level difference eliminating apparatus A from the lowermost part to the uppermost part will be described.

  The assistant 3a moves the wheelchair user 3 onto the pedestal 1 while the bridge 2 is stored in the pedestal 1 and the pedestal 1 is at the lowest position (step S101 in FIG. 3). Next, the assistant 3a uses the stairs 4 to reach a position where the operation panel 5 can be operated, and switches the changeover switch 5a to the driving side (step S102 in FIG. 3). At this time, since the step eliminating device A can only perform the ascending operation of the base 1, the control device 6 lights only the ascending button indicator light 5bl of the operation panel 5 (step S103 in FIG. 3). This informs the assistant 3a that the ascending button 5b should be operated.

  When the assistant 3a operates the ascending button 5b, the base 1 starts the ascending operation (steps S104 → S105 in FIG. 3). Then, as the assistant 3a continues to operate the ascending button 5b, the pedestal 1 rises to the same height as the top of the staircase 4, and the detection switch 1a operates. Thereby, the base 1 is automatically stopped (steps S106 → S107 in FIG. 3).

  At this time, since the step elimination device A can advance the bridge 2, the control device 6 turns off the indicator light 5bl of the ascending button 5b of the operation panel 5 and turns on the indicator light 5dl of the advance button 5d. (FIG. 3, step S108). As a result, the assistant 3a is informed that the operation of the ascending button 5b is completed and the advance button 5d should be operated next.

  When the assistant 3a finishes operating the ascending button 5b, the control device 6 also turns on the indicator light 5cl of the descending button 5c of the operation panel 5, but this should stop the use of the step difference eliminating device A. This is for displaying that the descent operation of the pedestal 1 is possible even when the descent operation of the pedestal 1 is attempted (step S109 in FIG. 3).

  Next, when the assistant 3a operates the advance button 5d, the bridge 2 starts the advance operation toward the uppermost floor surface of the stairs 4 (steps S201 → S202 in FIG. 4). Then, when the assistant 3a continues to operate the advance button 5d, the bridge 2 advances to the uppermost floor surface of the stairs 4, and the detection switch 2a operates. As a result, the bridge 2 automatically stops (steps S203 → S204 in FIG. 4). At this point, the wheelchair user 3 can be moved from the pedestal 1 to the top floor of the stairs 4 via the bridge 2, and the control device 6 displays the indicator light of the advance button 5 d of the operation panel 5. 5dl is turned off and the passage permission lamp 5fl is turned on (step S205 in FIG. 4). As a result, the assistant 3a is informed that the operation of the advance button 5d is completed and the wheelchair user 3 can move.

  In addition, when the assistant 3a finishes the operation of the advance button 5d, the control device 6 lights the backward button indicator light 5el of the operation panel 5. This is when the movement of the wheelchair user 3 is completed. This is for storing the bridge 2 and notifying the assistant 3a that it is necessary to lower the pedestal 1 and return the level difference eliminating device A to the original state (steps S206 → S207 in FIG. 4).

  Here, the assistant 3a receives the lighting of the passage permission light 5fl, moves the wheelchair user 3 from the pedestal 1 through the bridge 2 to the uppermost floor of the stairs 4 and uses the step elimination device A. The movement of the wheelchair user 3 from the bottom stairs 4 to the top tier 4 is completed (step S208 in FIG. 4).

  Next, the assistant 3a moves to the operation of returning the level difference eliminating device A to the original state, receives the lighting of the indicator light 5el of the reverse button 5e, operates the reverse button 5e, and performs the reverse operation of the bridge 2 ( FIG. 5 steps S301 → S302). At this time, since the detection switch 2a is released, the passage permission light 5fl is turned off (steps S303 to S304 in FIG. 5). Then, when the assistant 3a continues to operate the reverse button 5e, the bridge 2 continues to move backward and is stored in the base 1, and when the detection switch 2b operates, the bridge 2 automatically stops (step S305 in FIG. 5). → S306 → S307).

  At this time, since the step eliminating device A can perform the descent operation of the base 1, the control device 6 turns off the indicator lamp 5el of the reverse button 5e of the operation panel 5 and lights the indicator lamp 5cl of the descend button 5c ( FIG. 5 step S308). As a result, the assistant 3a is informed that the operation of the backward button 5e is completed, and then the lowering button 5c should be operated.

  When the assistant 3a finishes operating the backward button 5e, the control device 6 also turns on the indicator light 5dl of the advance button 5d of the operation panel 5, but this should try to use the step difference canceling device A again. Even when the assistant 3a tries to carry out the advancing operation of the bridge 2, it is for displaying that the advancing operation of the bridge 2 is possible (step S309 in FIG. 5).

  Next, when the assistant 3a receives the lighting of the indicator lamp 5cl of the lowering button 5c and operates the lowering button 5c, the base 1 starts the lowering operation toward the lowermost floor surface of the stairs 4 (step S401 in FIG. 6 → S402). Then, when the assistant 3a continues to operate the lowering button 5c, the base 1 is lowered to the vicinity of the lowermost floor surface of the stairs 4, and the detection switch 1b is operated. As a result, the pedestal 1 automatically stops (steps S402 → S403 → S404 in FIG. 6).

  At this time, since the descent operation of the base 1 is completed, the control device 6 turns off the descent button indicator light 5cl of the operation panel 5 (step S405 in FIG. 6). This also informs the assistant 3a that the pedestal 1 has arrived at the bottom, and the operation of the lowering button 5c ends.

  When the assistant 3a finishes operating the lowering button 5c, the control device 6 turns on the indicator light 5bl of the rising button 5b of the operation panel 5, which should be used again by any chance. Even when the assistant 3a tries to carry out the ascending operation of the pedestal 1, it is for displaying that the ascending operation of the pedestal 1 is possible (step S406 in FIG. 6).

  Next, the assistant 3a switches the changeover switch 5a to the inactive side, sets the step eliminating device A to the inactive state, and ends the use of the step eliminating device A (steps S407 → S408 in FIG. 6). At this time, the indicator light 5bl of the ascending button 5b is turned off, the indicator lights of all the operation buttons are turned off, and the step eliminating device A returns to the original resting state.

  In addition, about the normal operation button indicator lighting procedure in the case of moving the wheelchair user 3 from the top to the bottom of the stairs 4, since it is substantially the same as the contents explained above, the explanation is omitted here. .

  Next, when the wheelchair user 3 is moved from the lowermost part to the uppermost part using the step difference eliminating apparatus A, this implementation is performed when the assistant 3a interrupts the ascending driving operation of the base 1 in the middle. A processing operation related to the operation request notifying means as a feature of the embodiment will be described.

  When the assistant 3a is performing the ascending operation of the pedestal 1 by operating the ascending button 5b (step S104 → S105 in FIG. 3), before the detection switch 1a is operated, a danger is detected and the ascending button 5b is operated. Is interrupted, the pedestal 1 stops during the ascending operation (steps S106 → S121 → S122 in FIG. 3).

  This state is an unstable state for a wheelchair user 3 on the pedestal 1 that cannot move to the top floor of the stairs 4 or return to the bottom floor of the stairs 4. However, it is not preferable for safety to continue the state for a long time. Further, in this state, the pedestal 1 can be lifted or lowered, so that it is necessary to immediately notify the assistant 3a.

  Therefore, the control device 6 turns on both the indicator lamp 5bl of the ascending button 5b and the indicator lamp 5cl of the descending button 5c of the operation panel 5, and operates the button 3 with respect to the assistant 3a so that the pedestal 1 is moved to the maximum position. A request for the raising / lowering operation is made so as to move to the upper part or the lowermost part (step S123 in FIG. 3).

  Thus, by providing the control request | requirement notification means in the control apparatus 6, the assistant 3a will operate the raising button 5b immediately to restart the driving | operation of the base 1, if the danger etc. which perceived are solved. When the assistant 3a operates the ascending button 5b, the control device 6 turns off the indicator light 5cl of the descending button 5c, and the base 1 resumes the ascending operation (steps S124 → S125 → S105 in FIG. 3). Also, when the assistant 3a determines that the ascending operation is dangerous for some reason, if the assistant 3a operates the descending button 5c, the indicator lamp 5bl of the ascending button 5b is turned off by the control device 6, and the pedestal 1 performs the descending operation (steps S124 → S126 → S127 → FIG. 6, steps S401 → S402 in FIG. 3).

  Note that the processing operation related to the operation request notification means that is performed when the descent operation is interrupted in the middle is substantially the same as that in the above ascending operation, and thus the description thereof is omitted here.

  Next, when the wheelchair user 3 is moved from the lowermost step of the stairs 4 to the uppermost step using the level difference canceling device A, it is implemented when the assistant 3a interrupts the advance operation of the bridge 2 in the middle. A processing operation related to the operation request notification means will be described.

  When the pedestal 1 is in the uppermost position and the assistant 3a is performing the advance operation of the bridge 2 by operating the advance button 5d (step S201 → S202 in FIG. 4), there is a danger before the detection switch 2a operates. For example, when the operation of the advance button 5d is interrupted, the bridge 2 stops during the advance operation (steps S203 → S221 → S222 in FIG. 4). This state is an unstable state for a wheelchair user 3 on the pedestal 1 that cannot move to the top floor of the stairs 4 or return to the bottom floor of the stairs 4; It is not preferable for safety to continue the state for a long time. Further, in this state, since the advancing operation and the reverse operation of the bridge 2 are possible, it is necessary to notify the assistant 3a immediately.

  Therefore, the control device 6 lights both the indicator lamp 5dl of the advance button 5d and the indicator lamp 5el of the backward button 5e on the operation panel 5, and operates the bridge 2 by operating one of the buttons to the assistant 3a. A request for advancing / retreating operation is made so as to move to the uppermost floor of the stairs 4 or to store in the pedestal 1 (step S223 in FIG. 4).

  Thus, by providing the operation request notification means, the assistant 3a operates the advance button 5d to immediately resume the operation of the bridge 2 if the perceived danger or the like is solved. When the assistant 3a operates the advance button 5d, the control device 6 turns off the indicator light 5el of the reverse button 5e, and the bridge 2 resumes the advance operation (steps S224 → S225 → S202 in FIG. 4). Also, if the assistant 3a determines that the advance driving is dangerous for some reason, if the assistant 3a operates the backward button 5e, the indicator lamp 5dl of the advance button 5d is turned off by the control device 6, and the bridge 2 Performs a reverse operation (steps S224 → S226 → S227 → FIG. 5, steps S301 → S302 in FIG. 4).

  Note that the processing operation related to the operation request notification means that is performed when the reverse operation is interrupted in the middle is substantially the same as that at the time of the advance operation, and thus the description thereof is omitted here.

  Next, a description will be given of the processing operation related to the erroneous operation notification means, which is a feature of the present embodiment, which is performed when the assistant 3a operates the descending button 5c at the same time as the ascending button 5b during the ascending operation of the pedestal 1. To do.

  When the assistant 3a performs the ascending operation of the pedestal 1 by operating the ascending button 5b (step S104 → S105 in FIG. 3), before the detection switch 1a operates, the descending button 5c is mistakenly operated simultaneously with the ascending button 5b. When operated, the control device 6 stops the base 1 during the ascending operation (steps S106 → S121 → S141 → S142 in FIG. 3). In the control device 6, when both the indicator lamp 5bl of the ascending button 5b and the indicator lamp 5cl of the descending button 5c of the operation panel 5 are turned off, and the buttons are operated simultaneously on the assistant 3a, both buttons become invalid. (Step S143 in FIG. 3).

  Thus, by providing the erroneous operation notification means, when the assistant 3a erroneously operates during the ascending operation of the pedestal 1, it can be notified that the operation is immediately changed. When the assistant 3a stops the simultaneous operation of the ascending button 5b and the descending button 5c and operates only the ascending button 5b, the ascending button indicator light 5bl is turned on again by the control device 6, and the base 1 resumes the ascending operation. (FIG. 3 Steps S144 → S145 → S146 → S105).

  Further, when the assistant 3a switches to the lowering operation for some reason, if the assistant 3a stops the simultaneous operation of the ascending button 5b and the descending button 5c and operates only the descending button 5c, the controller 6 controls the lowering button 5c. The indicator lamp 5cl is turned on, and the pedestal 1 performs the descent operation (steps S144 → S145 → S147 → S148 → FIG. 6, steps S401 → S402 in FIG. 3).

  Note that the processing operation related to the erroneous operation notification means performed when the rising button 5b is mistakenly operated at the same time as the lowering button 5c during the lowering operation is substantially the same as that in the above-described rising operation. The description is omitted here.

  Next, the processing operation related to the erroneous operation notification means performed when the assistant 3a operates the backward button 5e by mistake simultaneously with the advance button 5d during the advance operation of the bridge 2 will be described.

  When the pedestal 1 is in the uppermost position and the assistant 3a performs the advance operation of the bridge 2 by operating the advance button 5d (step S201 → S202 in FIG. 4), the advancement is performed before the detection switch 2a is operated. If the reverse button 5e is mistakenly operated simultaneously with the button 5d, the control device 6 stops the bridge 2 during the advance operation (steps S203 → S221 → S241 → S242 in FIG. 4). Then, the control device 6 turns off both the indicator light 5dl of the advance button 5d and the indicator light 5el of the backward button 5e on the operation panel 5, and both buttons become invalid when the buttons are operated simultaneously on the assistant 3a. This is notified (step S243 in FIG. 4).

  As described above, by providing the erroneous operation notification means, when the assistant 3a erroneously operates during the advancing operation of the bridge 2, it is possible to notify immediately that the operation is changed. If the assistant 3a stops the simultaneous operation of the advance button 5d and the reverse button 5e and operates only the advance button 5d, the advance button indicator light 5dl is turned on again by the control device 6, and the bridge 2 resumes the advance operation. (FIG. 4, steps S244 → S245 → S246 → S202).

  When the assistant 3a switches to the backward driving for some reason, the assistant 3a stops the simultaneous operation of the advance button 5d and the backward button 5e and operates only the backward button 5e. 5el is turned on, and the bridge 2 performs the reverse operation (steps S244 → S245 → S247 → S248 → step S301 → S302 in FIG. 4).

  Note that the processing operation related to the erroneous operation notification means performed when the advance button 5d is erroneously operated simultaneously with the reverse button 5e during the reverse operation is substantially the same as the above-described advance operation, The description is omitted here.

  In the above description, the processing operation related to the erroneous operation notification means regarding the simultaneous operation of the up button 5b and the down button 5c and the simultaneous operation of the advance button 5d and the reverse button 5e has been described. The processing operation related to the above-described erroneous operation notification means also when the lowering button 5c is erroneously operated during the advancement operation, or when the advancement button 5d is erroneously operated during the downward operation of the base 1 by the operation of the lowering button 5c. Is applicable.

  The series of operation control is controlled by the control device 6 in the same manner as the lighting control of the indicator lamps, but the description thereof is omitted above.

  In this embodiment, the indicator lamp is turned on as an operation request or erroneous operation notification means. However, it is easy to replace this with voice guidance using a voice device or sentence guidance using a text display device. Is possible.

  As described above, according to the present embodiment, by providing the operation request notification means and the erroneous operation notification means, it is possible to perform operation guidance corresponding to the operation unique to the step elimination device A, and in the step elimination device A It is possible to deal with possible erroneous operations, and the convenience and safety of the user of the level difference eliminating device A can be improved.
