Abstract

PURPOSE:To provide an escalator device wherein the safety can be improved further with high space efficiency by restricting moving a wheelchair on a step. CONSTITUTION:Rear part and side part wheel stoppers 4F, 4G rising and falling by a drive part 4B built in a wheelchair loading particular step 4, so as to protrude/sink from a tread thereof, are arranged. Thus a device has a function of restricting moving in a rear part (front part when in down-operation) and both side parts of a wheelchair when it is placed on the tread. Further, the wheel stoppers 4F, 4G are formed in a constitution protruded/sunk from an irregular groove of the tread.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator device capable of mounting a wheelchair on a step.

[0002]

2. Description of the Related Art As a structure for carrying a transportation service by mounting a wheelchair on an escalator, there are known JP-A-3-293290 and JP-A-3-279194. The prior art described in the former publication has a configuration in which power is supplied to the step for mounting the wheelchair, and the conventional example described in the latter publication restricts the wheelchair on the tread surface, so that the vehicle is stopped at the rear end of the step. Is provided.

[0003]

SUMMARY OF THE INVENTION In these prior arts, mainly in order to prevent the wheelchair from falling from the tread, a lateral row of wheel stoppers appears and disappears only at the rear end of the tread, and in the width direction of the tread. There was no consideration for stopping the wheelchair in the correct position. For this reason, the wheelchair on the tread is restrained in the front-rear direction by wheel stoppers, but is free to move in the width direction of the tread, and, for example, the wheels of the wheelchair come into contact with the balustrade standing upright on both sides of the step. There was a problem that the wheelchair was dragged and the direction was changed. An object of the present invention is to provide an escalator device that restricts lateral movement of a wheelchair on a step to enhance safety and further has high space efficiency.

[0004]

In order to achieve the above object, the present invention provides a rear wheel stop body provided with a wheel stop body for a wheelchair mounting step over substantially the entire width of the rear end portion of this step, and to both sides of the step. The side vehicle stoppers are provided, while the vehicle stoppers are retracted and retracted by a single driving body. Further, both of these car stoppers are projected and retracted from the groove portion of the tread by a driving machine incorporated in the step.

[0005]

According to the present invention, since the rear wheel stoppers, which are retracted and retracted by the same operation in the same direction by one driving machine, are provided on the rear wheel substantially the entire width of the step and the side wheel stoppers, the tread surface is particularly effective. This eliminates the problem that the wheelchair does not lean toward the upper side, and the wheelchair comes into contact with the balustrade structure that causes relative movement with respect to the step. In addition, the drive device for both car stoppers is stored at the same position as the groove bottom surface of the tread built into the step, so it is compact overall and there is no obstacle such as collision even when the step engages with the comb of the entrance / exit. It becomes a storage structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an escalator device according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a side view of the lower entrance / exit section showing the structure of an embodiment of the present invention, and FIG. 2 is a sectional view of the main part of FIG.
In the figure, 1 is a lower entrance / exit, 2 is a comb-like comb, 3 is a step of general structure, 4 is a special step for wheelchair mounting (hereinafter abbreviated as special step), and 5 is a plurality of arranged step groups ( A chain connecting the symbols 3 and 4), 6
Reference numerals 7 and 7 are guide rollers, 8 and 9 are guide rails, 10 is side rails, and 11 is a balustrade structure which stands upright on both sides of the step 3 or the like.

Here, the special step 4 includes a drive unit 4B fixed inside by bolts 4A and the like, a pinion 4C, a rack 4D that meshes with the pinion 4C, a support 4E, and a rear car stop 4.
F, a side car stop 4G is provided, and when a wheelchair (not shown) moves from the entrance / exit 2 to the tread surface of the special step 4 and stands still, electric power is supplied from another place to rotate the drive unit 4B. , The pinion 4C attached to the main shaft thereof is rotated, and the latch 4D is operated by the driving force thereof, and at the same time, the rear vehicle stop body 4F and the side vehicle stop body 4 attached to the main frame 4H.
G is raised as shown. Furthermore, the rear bollard 4
F and the side wheel stopper 4G are attached to the main frame 4H, and the wheel of the wheelchair is raised from the state of being substantially flush with the groove bottom surface 4a of the tread to the state of height h by the driving force for raising and lowering the rack 4D. Restrained to prevent slipping to the rear part (in the case of ascending operation as shown by arrow A) or the front part (in the case of descending operation as shown by arrow B), and the side of the wheelchair can be freely moved by the side wheel stopper 4G. To prevent the side surface of the wheelchair from contacting the balustrade structure 11. The body 4 of the side car
The width l of G is not particularly limited as long as the required dimension is set according to the wheelchair to be mounted, but the number of rear wheel stoppers 4F and the overall width thereof are arranged over substantially the entire width of the special step 4. Is desirable.

In the special step 4 of one embodiment of the present invention,
The rear wheel stopper 4F and the side wheel stopper 4G are attached to the main frame 4H and are operated upward or downward by one drive unit 4B. The rear portion of the wheelchair (in the case of ascending operation as indicated by arrow A) and In addition to the drive unit 4B that is structured to act so as to restrain both sides and that is compactly built in the special step 4, drive system devices such as the pinion 4C and the rack 4D move synchronously in the same direction. Restrict movement on the treads of wheelchairs. The tops of both wheel stoppers are substantially flush with the groove bottom 4a of the special step 4, and the comb 2
It does not collide with.

[0010]

According to the present invention, a lateral movement of a wheelchair on a step can be restricted to enhance safety and provide an escalator device with high space efficiency.
