Ascending movement of the first wheelchair step 15 supported by the connecting arm 17 of the step 15 rises from the base of the second wheelchair step 18 and is supported at the position of the stepping plate surface of the first wheelchair step 15. Is provided.
[0009]
Reference numeral 20 denotes a vehicle stopper piece provided on the lower end 2 side of the main frame 1 of the second wheelchair step 18, which is driven by the movement of the transport belt 6 by engaging with the engaging mechanism 11 of the operating mechanism 8 raised when necessary. The displacement mechanism 21 projects and displaces upward. A wheelchair 22 is mounted on a wheelchair loading surface 23 formed mainly by the first wheelchair step 15 and the second wheelchair step 18 and is transported.
[0010]
The conventional escalator with a wheelchair step is configured as described above, and the operating mechanism 8 is normally in the lowered position, the inclined stepping plate 14 of the inclined wheelchair step 12 is in the horizontal position, and the connecting arm 17 of the first wheelchair step 15 is In the retreated position, the ascending tread plate 19 and the vehicle stopper piece 20 of the second wheelchair step 18 are respectively disposed in the descending position.
[0011]
In this state, the transport belt 6 is circulated within the main frame 1, and general passengers are transported by the steps 7, the step 12 for the tilt wheelchair, the step 15 for the first wheelchair, and the step 18 for the second wheelchair. It should be noted that all steps such as the first wheelchair step 15 are moved horizontally from the entrance 4 on the lower end 2 side in the ascending operation, and then gradually increased in inclination with an increasing inclination angle.
[0012]
Next, when the vehicle moves toward the entrance / exit 4 on the upper end 3 side by moving at a constant inclination with a constant inclination angle, the inclination angle gradually decreases and the inclination angle gradually decreases. Thereafter, it moves horizontally to the entrance 4 on the upper end 3 side and circulates. Note that during the descending operation, all the steps circulate in the reverse order as in the ascending operation.
[0013]
When the wheelchair 22 is transported up, that is, when the wheelchair 22 is transported from the entrance 4 on the lower end 2 side to the entrance 4 on the upper end 3 side, the wheelchair operation switch (not shown) of the escalator with a wheelchair step is used for wheelchair operation. Can be switched. As a result, the elevating mechanism 9 of the operating mechanism 8 is urged, and the engaging mechanism 11 is arranged at the raised position. Next, the transport belt 6 is raised.
[0014]
The inclined wheelchair step 12 moves horizontally from the entrance 4 on the lower end 2 side toward the upper end 3 side, whereby the inclination mechanism 13 is engaged with and driven by the engaging mechanism 11 of the raised operating mechanism 8. As a result, the inclined tread plate 14 is displaced and inclined as shown in FIG.
[0015]
Further, the first wheelchair step 15 moves horizontally from the entrance 4 on the lower end 2 side toward the upper end 3 side, whereby the advance / retreat mechanism 16 is engaged with and driven by the engagement mechanism 11 of the raised operating mechanism 8. . As a result, the connecting arm 17 projects and displaces toward the lower end side of the main frame 1 to support the ascending tread plate 19 as shown in FIG. In this state, that is, in the state shown in FIG. 33, the escalator is stopped and the wheelchair 22 enters the wheelchair loading surface 23 formed by the first wheelchair step 15 and the second wheelchair step 18 from the entrance 4 on the lower end 2 side.
[0016]
Then, when the driving button (not shown) is pushed after the wheelchair 22 is loaded, the escalator is lifted and activated, and the second wheelchair step 18 moves upward from the entrance 4 on the lower end 2 side toward the upper end 3 side. The displacement mechanism 21 is engaged with the engagement mechanism 11 of the actuating mechanism 8 and driven. As a result, the vehicle stopper piece 20 protrudes upward and protrudes from the tread surface of the second wheelchair step 18 as shown in FIG. Accordingly, the movement of the wheelchair 22 from the wheelchair loading surface 23 in the direction toward the lower end 2 of the main frame 1 is prevented.
[0017]
In the state shown in FIG. 34, when the transport belt 6 is driven up, the first wheelchair step 15 moves gradually and constantly. Even during this tilting movement, since the rising foot plate 19 of the second wheelchair step 18 is supported by the connecting arm 17 of the first wheelchair step 15, the wheelchair loading surface 23 is maintained. Then, the wheelchair 22 is lifted and conveyed in the state shown in FIG.
[0018]
Next, when the transport belt 6 moves so that the inclined wheelchair step 12 and the like are close to the horizontal movement position of the entrance 4 on the upper end 3 side, the engagement mechanism 11 and the inclination mechanism 13 of the operating mechanism 8 on the upper end 3 side of the main frame 1 Through the engagement, the inclined stepping plate 14 of the inclined wheelchair step 12 is disposed in the horizontal position. Further, the coupling arm 17 of the first wheelchair step 15 is disposed at the retracted position through the engagement of the engagement mechanism 11 and the advance / retreat mechanism 16, and the support of the rising step plate 19 is released.
[0019]
In this state, the transport belt 6 stops and the wheelchair 22 descends from the wheelchair loading surface 23 to the entrance / exit 4 on the upper end 3 side of the main frame 1. Thereafter, when the escalator is activated, the vehicle stopper piece 20 of the second wheelchair step 18 is disposed at the lowered position through the engagement of the engagement mechanism 11 and the displacement mechanism 21 of the operation mechanism 8. Next, the elevating mechanism 9 is urged and the operating mechanism 8 is disposed at the lowered position. As a result, the escalator with a wheelchair step returns to normal operation.
[0020]
[Problems to be solved by the invention]
In the conventional escalator with a wheelchair step as described above, the wheelchair loading surface 23 is formed so that the wheelchair 22 can be mounted without stopping the escalator with a wheelchair step. For this reason, while the inclined wheelchair step 12, the first wheelchair step 15 and the second wheelchair step 18 are passing over the operating mechanism 8 disposed near the entrance 4 at the end of the main frame 1, The wheelchair loading surface 23 is formed by operating through the engagement with the operation mechanism 8.
[0021]
Therefore, since the horizontal movement section of each step longer than a normal escalator is required near the end of the main frame 1, the overall length of the main frame 1 is increased, and the interval between the building beams supporting both ends of the main frame 1 is increased. . For this reason, there existed a problem that installation of the escalator with a wheelchair step was restrict | limited. In addition, the construction of remodeling an existing normal escalator with a short horizontal movement section into an escalator with a wheelchair step is also restricted.
[0022]
In addition, when the escalator with a wheelchair step of the structure by FIGS. 32-39 is applied to the length of the normal escalator, ie, the horizontal movement area of each normal step, the trouble described below will arise. That is, as shown in FIG. 37, the edge near the end of the main frame 1 of the step 18 for the second wheelchair is not separated from the comb 5 provided at the entrance 4 of the end of the main frame 1. A step is generated between the step 15 and the second wheelchair step 18 as the step 15 enters the gradually increasing inclination moving section and rises.
[0023]
For this reason, even if the rising step plate 19 of the second wheelchair step 18 is connected by the connecting arm 17 of the first wheelchair step 15, the comb 5 prevents the rising step plate 19 from rising. Therefore, it becomes impossible to raise the rising tread plate 19 as the first wheelchair step 15 starts to rise.
[0024]
On the other hand, as shown in FIG. 38, as shown in FIG. 39, the ascending tread plate 19 is raised at the position where the edge near the end of the main frame 1 of the second wheelchair step 18 is completely away from the comb 5. The wheelchair loading surface 23 is formed. And when it is set as the structure which makes the wheel stop piece 20 of the 1st wheelchair step 15 protrude after connecting with the step 18 for 2nd wheelchairs with the connection arm 17 and mounting the wheelchair 22, the operation | movement described below is required.
[0025]
That is, before the upward displacement of the rising foot plate 19 to be the same height as the step foot of the first wheelchair step 15, the base mechanism of the second wheelchair step 18 and the connection mechanism (not shown) of the rising foot plate 19 are connected. The operation | movement which cancels | releases and makes the raise tread 19 possible to raise is required. In response to this, the wheelchair transport operation by the wheelchair stepped escalator is performed as follows.
[0026]
First, the escalator is stopped, the base of the second wheelchair step 18 and the lift tread 19 are released, the lift tread 19 is lifted, the connecting arm 17 protrudes, the wheelchair 22 enters, the car stopper piece 20 protrudes, and the escalator is operated. Done by the procedure. In this procedure, the base of the second wheelchair step 18 and the lift tread 19 are released, the escalator is stopped, the lift tread 19 is lifted, the connecting arm 17 protrudes, the wheelchair 22 enters, the car stopper piece 20 protrudes, and the escalator is operated. It can also be a procedure.
[0027]
For this reason, the wheelchair 22 is operated between the two operations of releasing the coupling between the base of the second wheelchair step 18 and the rising stepping plate 19 and the operation of protruding the vehicle stopper piece 20 through the engagement with the one operation mechanism 8. It is necessary to perform boarding and upward displacement of the upward tread plate 19. Therefore, the above two operations cannot be performed simultaneously and by one operating mechanism 8.
[0028]
Furthermore, in order to make the wheelchair 22 easy to get in, in the configuration in which the boarding base protrudes as shown in FIG. 28 described later, the operation of getting in the wheelchair 22 is required between the operation of the boarding base protrusion and the car stopper piece 20 protrusion. . For this reason, the two operations of the boarding base protrusion and the car stopper piece 20 protrusion cannot be performed at the same time by the single operating mechanism 8.
[0029]
The present invention has been made to solve such a problem, and is to obtain an escalator with a wheelchair step that can be constituted by a main frame having a length corresponding to the horizontal movement section of each step near the entrance / exit in the normal escalator. Objective.

Is done. It should be noted that all steps such as the first wheelchair step 15 are moved horizontally from the entrance 4 on the lower end 2 side in the ascending operation, and then gradually increased in inclination with an increasing inclination angle.
[0054]
Next, when the vehicle moves toward the entrance / exit 4 on the upper end 3 side by moving at a constant inclination with a constant inclination angle, the inclination angle gradually decreases and the inclination angle gradually decreases. Thereafter, it moves horizontally to the entrance 4 on the upper end 3 side and circulates. Note that during the descending operation, all the steps circulate in the reverse order as in the ascending operation.
[0055]
When the wheelchair 22 is transported up, that is, when the wheelchair 22 is transported from the entrance 4 on the lower end 2 side to the entrance 4 on the upper end 3 side, the wheelchair operation switch (not shown) of the escalator with a wheelchair step is used for wheelchair operation.

The escalator stops when it faces the operating mechanism 24. At this time, the second wheelchair step 18 faces the second operating mechanism 37.
[0058]
Then, the electric motor of the elevating mechanism 25 is energized to raise the first operating mechanism 24, and the chain gear 58 provided on the driving shaft 57 of the first wheelchair step 15 is connected to the connecting arm driving mechanism of the first operating mechanism 24. It engages with the engagement strip 35 constituting the winding mechanism 36 of the 26. At the same time, the electric motor of the elevating mechanism 38 is energized and the second operating mechanism 37 is arranged at the raised position, resulting in the state shown in FIG.
[0059]
In this state, the lower end of the bracket 63 protruding from the lower surface of the ascending tread plate 19 of the second wheelchair step 18 is opposed to the ascending tread plate pressing body 47 of the second operating mechanism 37 in a state where a slight gap is formed. To do. Further, the chain gear 65 provided on the drive shaft 64 of the second wheelchair step 18 meshes with the engagement strip 42 constituting the winding mechanism 43 of the car stop drive mechanism 44 formed in the second operation mechanism 37. Then, in the state shown in FIG. 15, the electric motor 41 of the ascending tread plate coupling release mechanism 441 of the second operating mechanism 37 is energized to drive the engaging strip 42 constituting the winding mechanism 43.
[0060]
As a result, the chain gear 65 meshed with the engagement strip 42 rotates, and the drive shaft 64 of the second wheelchair step 18 rotates. Thereby, since the holding shaft 66 rotates via the gear mechanism 67, the rotation holder 70 also rotates together, and the notch 69 is disposed on the lower side. As a result, the holding body 71 can be moved downward from the notch 69, that is, the holding of the rotating holder 70 by the groove-like recess 68 is released.
[0061]
And in the state shown in FIG. 15, the electric motor of the raising / lowering mechanism 38 is urged | biased again, and the 2nd action mechanism 37 raises further. As a result, the ascending tread plate pressing body 47 causes the ascending tread plate 19 to be disposed at an upper position from the base of the second wheelchair step 18 via the bracket 63 to change from the state shown in FIG. 15 to the state shown in FIG.
[0062]
Next, in the state shown in FIG. 22, when the motor 34 of the winding mechanism 36 that constitutes the connecting arm drive mechanism 26 of the first operating mechanism 24 is energized, the engagement strip 35 is driven and is used for the first wheelchair. A chain gear 58 provided on the drive shaft 57 of the step 15 rotates. As a result, the transmission shaft 59 rotates via the drive shaft 57 and the gear mechanism 60, and the connecting arm 17 protrudes toward the lower end side of the main frame 1 by the operation of the rack 61 and the pinion 62.
[0063]
Thereby, the rising step board 19 arrange | positioned in the upper position from the base of the step 18 for 2nd wheelchairs is connected and supported by the connection arm 17 which protruded, as shown in FIG. The wheelchair loading surface 23 is formed by the first wheelchair step 15 and the rising stepboard 19 supported at the position of the stepboard surface of the first wheelchair step 15. In this state, the wheelchair 22 gets into the wheelchair loading surface 23 from the entrance / exit 4 on the lower end 2 side of the main frame 1.
[0064]
Next, the electric motor 41 of the vehicle stop drive mechanism 44 of the second operation mechanism 37 is energized, and the engagement strip 42 constituting the winding mechanism 43 is driven. As a result, the chain gear 65 meshed with the engagement strip 42 rotates, and the drive shaft 64 of the second wheelchair step 18 rotates. As a result, the transmission shaft 72 rotates via the gear mechanism 73, and the vehicle stopper piece 20 protrudes and displaces upward from the rising tread plate 19 by the operation of the rack 74 and the pinion 75. Thereby, the state shown in FIG. 2 or 22 is obtained, and the movement of the wheelchair 22 from the wheelchair loading surface 23 toward the lower side 2 of the main frame 1 is prevented.
[0065]
Then, after the first operating mechanism 24 and the second operating mechanism 37 are disposed at the lowered position in the state shown in FIG. 22, when the transport belt 6 is driven up, the first wheelchair step 15 and the like are gradually inclined and moved. Move at a constant inclination. Even during this tilting movement, since the rising foot plate 19 of the second wheelchair step 18 is supported by the connecting arm 17 of the first wheelchair step 15, the wheelchair loading surface 23 is maintained. Then, the wheelchair 22 is lifted and conveyed in the state shown in FIG.
[0066]
Next, when the transport belt 6 moves and the step 12 for the tilted wheelchair approaches the entrance / exit 4 on the upper end 3 side, the case for the tilted wheelchair is almost opposite to the case of ascending from the entrance / exit 4 on the lower end 2 side of the main frame 1. The step 12 and the like operate. That is, when the inclined wheelchair step 12 passes the position of the first operating mechanism 24 on the upper end 3 side of the main frame 1, the detailed description is omitted, but the inclined stepping plate 14 is guided horizontally by another guide (not shown). It returns to the position and is held in the horizontal position via the rotation holder 52.
[0067]
24, the transport belt 6 further moves from this state, the transport belt 6 stops in the state shown in FIG. 25, and the wheelchair 22 descends to the entrance 4 on the upper end 3 side. Then, the first operation mechanism 24 rises with respect to the first wheelchair step 15 and the second operation mechanism 37 rises with respect to the second wheelchair step 18. In this state, first, the connecting arm 17 is retracted by the operation of the first operating mechanism 24, and the connection with the second wheelchair step 18 is released.
[0068]
Next, the operation of the second operation mechanism 37 causes the vehicle stop piece 20 to descend through the operation of the vehicle stop drive mechanism 44, and the lower operation plate 37 descends due to the lowering of the second operation mechanism 37, resulting in the state shown in FIG. Since the two wheelchair steps 18 are arranged in the gradually decreasing inclination moving section, a step that is lowered with respect to the first wheelchair step 15 is generated. Next, the lifting step board 19 and the base are coupled by driving the winding mechanism 43 of the ascending tread board coupling release mechanism 441. Thereafter, the first operating mechanism 24 and the second operating mechanism 37 are lowered, and the wheelchair stepped escalator returns to normal operation.
[0069]
The case where the wheelchair 22 is transported from the entrance 4 on the lower end 2 side to the entrance 4 on the upper end 3 side has been described above. However, when transporting the wheelchair 22 from the entrance / exit 4 on the upper end 3 side to the entrance / exit 4 on the lower end 2 side, the related devices such as the first operating mechanism 24 and the second operating mechanism 37 are also referred to as ascending transport of the wheelchair 22. By operating in reverse, detailed description is omitted, but the same effect as when the wheelchair 22 is lifted and conveyed can be obtained.
[0070]
As described above, the wheelchair loading surface 23 is formed in a state in which either the first wheelchair step 15 or the second wheelchair step 18 moves and stops in the gradually increasing or decreasing inclination moving section. . Therefore, the wheelchair 22 can be boarded and lowered without providing a horizontal movement section of each step longer than a normal escalator near the end of the main frame 1.
[0071]
Thereby, it becomes unnecessary to increase the total length of the main frame 1 or increase the interval between building beams that support both ends of the main frame 1. Therefore, it is possible to eliminate restrictions on installing an escalator with a wheelchair step, and restrictions on remodeling an existing normal escalator to an escalator with a wheelchair step.
