[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator device that can be used safely not only by ordinary passengers but also by special passengers who use vehicles such as wheelchairs, strollers and shopping carts.

[0002]

2. Description of the Related Art Since a conventional escalator is intended to transport a general healthy person, the depth of steps is about 40.
It is about 0 mm. Therefore, it has been difficult to safely transport a vehicle such as a wheelchair or a stroller in a horizontal state due to its dimensions.

[0003] For this reason, various proposals have already been made. One of the proposals is to incline the tread plate 1a in step 1 of the escalator so as to create a space on which vehicles can be mounted, as shown in FIG. There is an escalator that was thought to be.

In order to prepare the step board 1a of step 1 to be free to tilt and to provide a free step in which the tilt angle is changed according to the step between the step 1 and the step 2 below the step 1, it is necessary to make the step 3a. As shown in Japanese Patent No. 12797, a device in which a pin is protruded from a tiltable step side toward a lower step to deposit its own weight in the lower step simplifies the device configuration most. (Of course, a configuration in which the pin is provided in the lower step and the pin protrudes toward the upper step may be used.)

FIG. 3 is a perspective view showing the relationship between the tiltable step 1 and the lower step 2, and FIG. 4 is an enlarged view showing the driving mechanism of the pin 3 in FIG. Is protruded into the pin receiver 2a on the lower step side, or the pin 3 is retracted so that the pin 3 can be locked and locked so as to be tiltable.

[0006]

However, in such a method of inserting and removing the pin 3 with the rack and pinion mechanism 4,
It is necessary to install a motor on the truss side and engage this motor with the rack and pinion mechanism 4 built in the tiltable step 1 to operate the mechanism. Each time the escalator is used by a wheelchair passenger or the like, the flow of traffic is cut off, and the original function of the escalator, that is, continuous transportation, is significantly reduced. The present invention has been made in view of the above points, and an object of the present invention is to provide an escalator device capable of modifying a step without necessarily stopping when a passenger using a vehicle uses an escalator.

[0007]

According to the present invention, of a plurality of steps constituting an escalator, one of at least one set of adjacent steps is provided with a pin, and the other is provided with a pin receiver. In the escalator for tilting the tread of the step above the adjacent step by the engagement of the step, the pin is slidably supported toward the pin receiver, and a rod having a roller at the lower end is provided so as to be movable up and down. When the pin is in the raised position, the pin is engaged with the pin receiver, and when the rod is in the lowered position, the upper end of the rod and the pin are connected so that the pin maintains the disengaged state with the pin receiver. Is provided with an additional device for applying an external force in the vertical direction.

[0008]

With the above construction, the adjacent steps can be freely engaged and disengaged irrespective of whether the steps are moved or not.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view of a tiltable step according to the present invention, and FIG. 5 is an explanatory view for explaining a mechanism according to the present invention. In the drawings, the same reference numerals as those in FIGS. 2 and 3 denote the same parts. As shown, 10 is a tiltable step according to the present invention,
Reference numeral 11 denotes a rod provided in a tiltable step so as to be able to move up and down by a guide member 11a. A lower end is provided with a rotatable roller 12, and a support member 13 having an elongated hole 13a is fixed to an upper end. . The support member 13 serves as a stopper so as to contact the guide member 11a and prevent the rod 11 from descending further. 14 is the link piece 1
4a and 14b, the link pieces 14a and 14b
b of the supporting member 13 is guided by the elongated hole 13a of the supporting member 13, and the other end of the link piece 14b is tiltable.
0, and the other end of the link piece 14a is connected to one end of the pin 15. The pin 15 is connected to the guide member 16
Is provided in the step 1 which can be slidably (projected freely). A spring 17 applies a biasing force (counterclockwise in FIG. 1) to the link piece 14b.

On the other hand, a movable guide rail 20 is provided on the truss side near the entrance of the escalator so as to be movable up and down.
The roller 12 of the rod 11 is guided.

Next, the operation of the device of the present invention will be described with reference to the drawings. During normal operation, the movable guide rail 2
Since 0 is in the lowered position, the rod 11 is also kept in the lowered position, so that the link 14 is held in the state shown in FIG. 1 by the spring force of the spring 17 and the pin 15 is held in the retracted position. Accordingly, the tiltable step 10 is operated in the same state as the normal step.

On the other hand, when a vehicle such as a wheelchair is transported, the movable guide rail 20 is first raised when the tiltable step 10 is passing through the section of the movable guide rail 20 arranged near the landing, As shown in FIG. 5, the roller 11 is lifted to raise the rod 11, and the link piece 14b is rotated clockwise against the spring force of the spring 17, so that the connecting portion 14 of the link 14 is rotated.
c slides the long hole 13a of the support member 13 to the left, and causes the pin 15 to protrude downward to the step 2 side.

Further, when the rod 11 is further raised by the movable guide rail 20 until the support member 13 comes into contact with the back surface of the tread plate, the link piece 14b is urged clockwise by the spring force of the spring 17, so that Roller 12
Even if the guide is disengaged from the movable guide rail 20, the link 14 and the pin 15 maintain the state shown in FIG.

Thereafter, the tiltable step 10 moves,
When the step with the lower step 2 changes as shown in FIGS. 6 (a), 6 (b) and 6 (c), since the protruding pin 15 owes its own weight to the pin receiver 2a of the lower step 2, Accordingly, the tiltable step 10 is appropriately tilted.

The step 10 which can be tilted even in the middle part is a pin 1
5 is supported by the pin receiver 2a as it is, so that the rollers 1
No guide rail is required to guide 2.

Thereafter, when the tiltable step 10 arrives near the landing, the movable guide rail is lowered while the roller 12 passes through the movable guide rail (not shown), as opposed to the landing. Then, the roller 12 and the rod 11 are pulled down to retract the pin 15, thereby restoring the normal step state. Therefore, if the movable guide rail is moved up and down while the roller 12 passes through the movable guide rail, the steps can be freely modified and restored even while the escalator is operating.

In the above description, the embodiment has been described in which the pin 15 is provided on the tiltable step 10 and the pin receiver 2a is provided on the lower step 2, but the pin is provided on the lower step 2 and the pin receiver is provided on the tiltable step 10. It may be configured such that adjacent steps can be engaged and disengaged.

In the above description, the tiltable step 10 is used.
The description of the lock device for the movable tread plate 10a is omitted, but the pin 15 is arranged obliquely with respect to the tiltable step 10 as in the case of the prior art, and the link piece 1
It is sufficient to connect 4a to the middle of pin 15 so that the rear end of pin 15 is used for the locking device.

[0019]

[Effects of the Invention] As described above, according to the present invention, even if the escalator step is in a moving state, the step can be tilted and restored freely, so that passengers using vehicles such as wheelchairs can be used. However, it is not always necessary to stop the escalator, and both the healthy person and the vehicle user can use the escalator simultaneously and very naturally.
