- the trumpet shape of the escort rail 3 is also narrowed. However, as described above, the carriage 4 is restrained in the width direction by the poles 25 and 26. The mechanism 6 is guided toward the center of the escort rail 3.
- FIG. 11 Immediately after the carriage 4 enters between the poles 25 and 26, the portion B (see FIG. 9) where the copying in the escort rail 3 and the mechanism 6 are engaged is shown in FIG. 11 (b).
- the copying mechanism 6 has a member 3b that restrains the mechanism 6 to the lower side, and the copying mechanism 6 has a dimension that cannot be removed from the escort rail 3. Therefore, the copying mechanism 6 is erroneously detached from the escort rail 3. There is no end to it.
- the portion C (see Fig. 9) where the copying mechanism 3 of the escort rail 3 is engaged is a metal having high rigidity as shown in Fig. 11 (c). It is firmly formed by the manufactured additive 3c. The tip of the workpiece 3c is pointed so that the copying mechanism 6 can be easily engaged, and the copying mechanism 6 can easily shift to this portion C.
- FIG. 11 A portion D (see Fig. 9) from the boarding / exiting portion 24 just before the carriage 4 on the escort rail 3 to the step to the middle of the bent portion leading to the inclined portion of the escalator is shown in Fig. 11 (d). Since the copying mechanism 6 is guided with a strong force by the workpiece 3c having high rigidity and the member 3b for restraining the lower side, the carriage 4 can be controlled to a desired posture.
- FIG. 12 is an explanatory diagram of the structure of the escalator according to the fourth embodiment of the present invention.
- symbol is attached
- the carriage 4 also has the upper surface force of step 2 through the comb-shaped member 31 and the boarding / exiting portion 24.
- the surface of the escort rail 3 that guides the copying mechanism 6 is bent in the middle so that the center of gravity G of the carriage 4 moves upward by a predetermined distance to a desired height. is there.
- the center of gravity G of the carriage 4 includes the luggage in a state where the carriage 4 is loaded with a luggage of a predetermined size and weight.
- the shape of the escort rail 3 formed so that the center of gravity G of the carriage 4 has a desired height is that when the carriage 4 moves from step 2 to the boarding / exiting section 24, the center of gravity of the carriage 4 changes from before the transition.
- the shape is such that the height of the center of gravity G is slightly higher when the carriage 4 is on the upper surface of the step 2 than when the carriage 4 is on the upper surface of the boarding / exiting portion 24.
- the escort rail 3 has a center of gravity G of the carriage 4 where the upper surface force of the carriage 4 force step 2 moves to the getting-on / off part 24, which is slightly higher through the comb-shaped member 31. Since the height of the vehicle does not change or is slightly lower, the top surface force of Step 2 is also directed toward the boarding / exiting section 24. The carriage 4 moves smoothly to the boarding / exiting section 24 with little force applied. Even if you are standing behind the trolley 4, you will not be in a dangerous situation where you will not be blocked by the trolley 4 in front.
- Fig. 12 (b) when considering the case where the carriage 4 moves from the boarding / exiting portion 24 to the upper surface of Step 2 which is slightly lowered through the comb-shaped member 31, the escort rail is considered.
- the shape of 3 is such that the center of gravity G of the carriage 4 does not change or is slightly higher. Because of this shape, the carriage 4 heading from the boarding / exiting section 24 to the upper surface of Step 2 does not move to the upper surface of Step 2 unless a little force is applied. If 4 naturally moves to the upper surface of Step 2, it will not cause any trouble to other passengers who have already boarded.
- FIG. 13 is a plan view of the vicinity of the getting-on / off part of the escalator according to the fifth embodiment of the present invention.
- symbol is attached
- a cart detection sensor 32 and a human sensor 33 for detecting the congestion state of passengers are provided in the vicinity of the boarding / exiting portion 24 where the passenger exits and the carriage 4 is located in front of the boarding / exiting portion 24.
- An emergency switch 34 is provided in the vicinity of the handrail belt 23 on the side where it is mounted. Based on the input information of the cart detection sensor 32, the human sensor 33, and the emergency switch 34, the control device 3 5 slows, stops, or accelerates step 2.
- the cart detection sensor 32 is, for example, an IC chip 32a embedded in a part of the cart 4 such as the copying mechanism 6, and a chip in a portion of the escalator close to the cart 4 (for example, the escort rail 3).
- the power provided with the information reading devices 32b and 32c can be considered as an example.
- the human sensor 33 is attached to a ceiling or the like overlooking the entire getting-on / off part 24.
- the control device 35 slows, stops, or accelerates the speed of Step 2 based on the input information of the cart detection sensor 32, the human detection sensor 33, and the emergency switch 34, so that the entrance / exit 24 Even if it gets crowded with passengers who get off the road, it will be in a state of being blocked up.
- the cart detection sensor 32 since the IC chip 32a is embedded in the copying mechanism 6 of the cart 4, the chip information readers 32b and 32c equipped on the escort rail 3 are detected from the boarding / exiting section 24.
- the controller 35 can detect the input / output information power of the chip information readers 32b and 32c and know the stagnation state of the carriage 4 at the getting-on / off unit 24.
- the control device 35 can know the congestion status of the boarding / exiting unit 24 as well. Although this human sensor 33 may monitor the entire boarding / exiting section 24, only the passengers come and go on the side where the carriage 4 does not pass, and it is not necessary to manage the number of people passing by. Therefore, the human sensor 33 only needs to detect the congestion state of the area 24a on the side where the escort rail 3 is located in the getting-on / off part 24.
- the control device 35 slows down the speed of Step 2 before it becomes dangerous or eliminates the previous congestion. If not, stop in case of V, or accelerate step 2 if the previous congestion is cleared.
- the emergency switch 34 arranged near the handrail belt 23 on the side where the cart 4 is mounted can be pressed to 2 can be decelerated to a stop.
- the announcement that “it starts to move slowly if you press it again” also causes the speaker power not shown to flow.
- emergency switch 34 is pressed again, the “released” announcement is made, but step 2 is reduced for a certain amount of time. Drive at high speed and then re-accelerate to normal speed. If emergency switch 34 is pressed again during this movement start step 2 will decelerate and stop.
- the emergency stop function based on the judgment of the passenger is prioritized over the automatic deceleration stop function using the cart detection sensor 32 and the human sensor 33 described above. If both sensor 33 fails, it will not be dangerous.
- the restricting member for restricting the passage of the escalator carriage is provided in the lower floor getting on / off portion.
- the restricting member is the upper floor getting on / off portion, or It may be installed in both the upper and lower floors.
- the present invention can also be applied to an escalator provided with a horizontal portion in which the step moves horizontally in the middle of the inclined portion in which the step moves obliquely.
- the escalator of the present invention is such that when the escalator carriage is to be put on the step, the escalator carriage passes through the getting-on / off section unless the copying mechanism of the escalator carriage is engaged with the guide section. Therefore, it is safe to avoid a dangerous state where the copying mechanism is not engaged with the guide portion due to an operation error or a depression error.
