Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an escalator device that can be shared by general passengers and wheelchair users for the physically disabled, and particularly relates to a space configuration for loading a wheelchair.

[Conventional technology]

Conventional escalator equipment usually has a depth of 40cm.
The train is equipped with several steps, and is configured to transport general passengers by circulating a large number of steps.

[Problem that the invention seeks to solve]

Transporting a wheelchair user using the conventional escalator device as described above is so dangerous that it is practically impossible even in the presence of a caregiver.

This invention was made in order to solve the above-mentioned problems, and an object thereof is to obtain an escalator device that can stably load wheelchairs.

[Means for solving problems]

The escalator device according to the present invention is provided with wheelchair steps equipped with an extendable auxiliary plate between the steps for general passengers, and protrudes through the extension of the auxiliary plate to operate a stop device at the end of the conveyance path. An actuating device is provided to cause the operation to occur.

[Effect]

In this invention, normal operation for transporting general passengers is performed with the auxiliary board stored in the steps, and the auxiliary board is extended from the steps to form a space for loading a wheelchair, and the wheelchair transport operation is performed. Furthermore, when transporting a wheelchair, the escalator automatically stops at the arrival end of the transport path using an activation device and a stop device.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, 1 is the main frame of the escalator, 1a is the main frame 1
At the end of the escalator, an escalator entrance is provided. Reference numeral 2 denotes a first type step in which a large number of steps are connected to the main frame 1 and arranged in an endless manner, 2' is a second type step arranged between these steps, 2a is a tread of the second type step 2', 2b is a void formed in the tread 2a and opened on the lower end 1a side of the main frame 1; 2c is a riser attached to the lower part of the second type step 2' on the lower end 1a side of the main frame 1; 2d is a space A lid whose upper edge is pivotally attached to the upper surface of the step board 2a and covers the opening of the space 2b, 2e is a first auxiliary plate arranged in the space 2b and configured to be able to slide inside the space 2b, and 2f is a lid that covers the opening of the space 2b. A second auxiliary plate 3 arranged inside the second auxiliary plate and configured to be slidable with respect to the first auxiliary plate 2e.
is an L-shaped bent part provided in the footboard 2a and pivotally supported by a pin 3a on the side opposite to the opening of the empty space 2b.
3b is a torsion spring that is fitted onto a pin 3a and held at both ends by the tread plate 2a and the actuating device 3, respectively, to urge one side of the L-shaped fitting toward the outside of the side surface of the tread plate 2a; Reference numeral 5 indicates a stopping device consisting of a limit switch fixed near the end portion 1a of the main frame 1 and provided corresponding to the actuating device 3. Reference numeral 5 indicates a wheelchair.

That is, the first auxiliary board 2e is always the footboard 2a.
2, the second auxiliary plate 2f is housed in the first auxiliary plate 2e, and the lid 2d is held to close the opening of the cavity 2c, and is arranged as shown by the solid line in FIG. In this arrangement, the actuating device 3 is in a state shown by dotted lines in FIG. 3, with one side of the L-shaped metal fitting being pressed by the first auxiliary plate 2e and the other side being held in a position retracted from the side of the second type step 2'. becomes. Then, with the first and second auxiliary plates 2e and 2f housed in the second type step 2', a drive device (not shown)
energized, both the first and second type steps 2, 2' are operated in circulation to transport general passengers. Also,
Now, when transporting a wheelchair user, the second class step 2'
When the escalator reaches one end of the main frame 1, the drive device is deenergized and the escalator is stopped. Then cover 2d
When the first and second auxiliary plates 2e and 2f are opened and the first and second auxiliary plates 2e and 2f are pulled out, the first and second auxiliary plates 2
The upper surfaces of e and 2f are arranged at positions corresponding to the upper surface of the footboard 2a. Further, by pulling out the first auxiliary plate 2e, the pressure on the actuating device 3 is released and the torsion spring 3b rotates, so that one side of the L-shaped fitting is attached to the footboard 2.
Protrudes from the a side. The wheelchair 5 is mounted on the upper surfaces of the first and second auxiliary plates 2e, 2f and the footboard 2a. Then, when the drive device is energized, the second type steps 2' and the like move toward the other end 1a of the main frame 1,
When a predetermined position is reached, the stop device 4 is pressed and operated by the protruding actuating device 3, and this operation deenergizes the drive device and stops the second type step 2' and the like. As a result, the wheelchair 5 is carried out from the footboard 2a and the first and second auxiliary boards 2e, 2f to the entrance at the end 1a where the wheelchair 5 has arrived. In this way, the wheelchair 5 can be easily and safely transported between the entrances and exits by the escalator. After the wheelchair has been transported, the first and second auxiliary plates 2e and 2f are stored in the treadle 2a, and as the first auxiliary plate 2e is stored, the actuating device 3 is retired and the stopping device 4 becomes inactive. General passengers will be transported.

6 to 9 show other embodiments of the present invention. In the figures, the same reference numerals as in FIGS. A recess 2e is disposed in a fitted state in the recess 2b and is opened toward the lower end 1a of the main frame 1.
An auxiliary plate whose lower edge on the a side is pivotally connected to the edge of the tread plate 2a,
Reference numeral 3 designates an actuating device that is provided on the footboard 2a and is retracted when pressed by the auxiliary board 2e.

That is, also in this embodiment, the auxiliary board 2e is folded and stored in the second type step 2', and the auxiliary board 2e is folded and stored in the second type step 2'.
The operating device 3 is retracted to transport ordinary passengers. Then, the auxiliary plate 2e is rotated and extended so that its upper surface is placed in a position corresponding to the upper surface of the recess of the tread plate 2a,
Moreover, the actuating device 3 protrudes by extension of the auxiliary board 2e, and the wheelchair 5 is transported by the extended auxiliary board 2e and footboard 2a. Therefore, although a detailed explanation will be omitted, it is clear that the same effects as in the embodiments shown in FIGS. 1 to 5 can be obtained in this embodiment as well.

〔Effect of the invention〕

As explained above, the present invention provides a large number of first
At least one type 2 step is provided between the seed treads, and an auxiliary board is provided on the second type step, which is normally stored and extended when necessary, and on which the wheelchair is mounted by the upper surface of the second type step; Further, the second type step is provided with an actuating device that protrudes when the auxiliary plate is extended to operate a stopping device provided at the end of the main frame. This makes it possible to transport the wheelchair easily and safely, and also realizes a highly safe escalator device that can automatically stop the second class steps at the end of the main frame when the wheelchair is loaded. It is something to do.
