[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair step escalator in which a wheelchair step to which a wheelchair is transformed when a wheelchair is driven is provided between normal steps.

[0002]

2. Description of the Related Art FIG. 14 is a schematic side view showing an example of a conventional stepped escalator for wheelchairs. In the figure,
Reference numeral 1 is a main frame, 2 is a circulation path provided in the main frame 1, 3 is an endless step, which is a step that circulates along the circulation path 2. This step 3 is a plurality of steps transformed during wheelchair driving ( The wheelchair steps 3a (for example, 3) and the remaining normal steps 3b. Reference numeral 4 is a balustrade standing upright on both sides of the step 3 on the main frame 1, and 5 are entry / exit portions located at both ends of the escalator.

FIG. 15 is a sectional view of the boarding / alighting section 5 of FIG. In the figure, 6 is a bottomed cylindrical pole case embedded in the floor surface 5a of the boarding / alighting section 5, and an opening 6a is provided at the upper end of the pole case 6. A protrusion 6b is provided on the inner wall surface of the pole case 6 near the opening 6a. Reference numeral 7 denotes a columnar pole which is inserted into and removed from the pole case 6 so that the side surface of the pole 7 is substantially L-shaped to engage with the protrusion 6b as shown in FIGS. A character-shaped engaging groove 7a is provided.

In the conventional wheelchair-equipped step escalator configured as described above, the driving of the step 3 is stopped while the wheelchair step 3a is adjacent to the floor surface 5a of the entry / exit portion 5, as shown in FIG. After that, the wheelchair step 3a
Put on. Further, the wheelchair steps 3a are transformed by the wheelchair driving command, and the wheelchair steps can be moved while the wheelchair is on.

Thus, after the wheelchair is completely placed on the transformed wheelchair steps 3a, the steps 3 are driven again.
Since only one set of wheelchair steps 3a is included in the steps 3, it is very dangerous if another wheelchair enters the escalator while driving the wheelchair. Therefore, when starting wheelchair driving, the pole 7 is set up on the floor surface 5a of the entry / exit portion 5 to prevent other wheelchairs from entering.

In order to stand the pole 7, the pole 7 is pulled up by holding the upper end, and when the projection 6b comes into contact with the wall of the engaging groove 7a, the pole 7 is rotated 90 °, and the projection 6b is re-established. The pole 7 may be released when it comes into contact. Here, since one staff member is always present when driving the wheelchair, the staff member takes charge of the pole 7 in and out.

FIG. 18 is a perspective view showing the boarding / alighting section 5 with the pole 7 of FIG. 14 standing upright. An entry blocking means 9 composed of a chain, a rope or the like is provided between the eight. Further, FIG. 19 is a plan view of FIG. 18, but the distances L ₁ and L ₂ between the pole 7 and the struts 8 on both sides of the pole 7 are both smaller than the width of the wheelchair.

A handle 7c that crosses the recess 7b is attached.
Therefore, a staff member can carry out the work of taking in and out the pole 7 by grasping the handle 7c.

[0009]

In the conventional wheelchair-equipped escalator having the above-described structure, dust, sand, and the like are contained in the pole case 6 through the gap around the pole 7.
Since pebbles and water (especially a large amount of water used when cleaning the floor) enter, the movement of the pole 7 is impaired, and the pole 7 is damaged and corroded. Further, if the pole 7 is pulled up while dust or water adheres to the side surface, the passenger's clothes may be soiled. Further, in order to prevent these, there is a problem that it takes time to clean the inside of the pole case 6 and the pole 7. Furthermore, since a large recess 7b is provided at the upper end of the pole 7 and the recess 7b is exposed on the floor surface 5a, there is a problem that passengers may trip and fall. In addition, since a person other than the staff member can easily put in and take out the pole 7, there is a problem in that there is a risk of being mischievous.

The present invention has been made to solve the above problems, and it is possible to prevent dust, water, etc. from entering the pole case, and the passenger trips over the pole. An object of the present invention is to obtain an escalator with steps for wheelchairs, which can prevent the user from falling and falling, and can prevent the pole from being taken in and out due to mischief.
