Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an escalator suitable for transporting wheelchairs and the like.

[Background of the invention]

In today's era of efforts to improve the welfare environment, it is desirable to adopt transportation systems and architectural structures with special innovations that allow even disabled people in wheelchairs to move around relatively freely.

Recently, escalators are expected to emerge as escalators that can be easily used even by disabled elderly people, as escalators are an indispensable means of transportation within buildings.

However, at present, the installation angle and operating speed, which greatly affect the psychology of escalator users, do not cause any inconvenience to healthy people, but elderly people and people with physical disabilities find it difficult to get on and off the escalator. For these people, escalators cannot be used because of the lack of scattering, so for these people, the installation angle should be reduced to increase the sense of stability when riding, and the transportation speed should be slowed to make it easier to get on and off. It has been proposed that

In addition, for those who have difficulty walking and use a wheelchair, we have made it possible to use the service while in a wheelchair! An escalator with special consideration is desired.

Furthermore, it was not possible to safely ride a shopping cart in a department store or the like. This is because wheelchairs and carts have wheels and generally do not ride stably on stepped treads.

Conventionally, there are roads that are generally called electrified roads and have no steps on the tread surface 85, but the entire tread surface slopes like a slide and the wheelchair is not stable. There was a drawback that the swath efficiency deteriorated.

As a measure to solve these shortcomings, the special public
It has been proposed, as in No. 1555, that a specific step be installed in the group of steps of a regular escalator, and that specific step be stopped, and after the wheelchair has been placed on it, it is restarted and carried to the nearest floor. There is. As an example of this specific step, an example using a large step is shown.

However, when large steps are arranged, there is a problem that a large step difference occurs between adjacent steps.

As a means of solving this problem, Japanese Patent Application Publication No. 59-172376
No. is proposed. In this method, between the general steps,
A specific step is provided in which a part of the step can move only in the vertical direction relative to the step, and the liftable tread of this specific step is moved through the circulation of the general step through a push-up mechanism. By using the operating rail of the push-up mechanism installed separately from the road to push up the treads to the same height as the treads of the adjacent general steps, the area of the treads is expanded to secure space for loading wheelchairs, etc. It is.

Here, if we consider two adjacent steps specifically, a typical escalator is near the entrance/exit.

The tread surfaces of adjacent steps are kept at approximately the same height, and the width of the tread surfaces of these two adjacent steps is.

It is twice the tread surface of one step. but.

When these steps move to the slope, the height of the tread surface of each step changes relatively, and at the same time as this change in height direction, the front (the side that is one slope above the slope) position K The rear (opposite to the front) end of the step protrudes relatively to the step 91 located at the rear. Therefore, the horizontal distance between two adjacent steps in the inclined portion becomes shorter by the amount of the protrusion.

According to the above-mentioned known example, a part of the tread surface moves only in the vertical direction relative to the step, so that the two steps do not interfere with each other.

The tread that rises is made smaller by an amount corresponding to the above-mentioned amount of protrusion, and the loading space for wheelchairs, etc. is made up of the step from which a part of the tread rises, and the step adjacent to the front VC of this step. is obtained by keeping the tread surfaces of the two steps at the same height by protruding the intermediate inclined portions of the steps adjacent to the front of the two M steps. The width of the effective plane for loading wheelchairs and the like is twice the width of the tread surface of one step minus the width equivalent to twice the amount of protrusion described above.

In addition, according to the above-mentioned known example, the distance between the treads of two steps for holding a loading space for wheelchairs, etc. changes between the first entrance and the intermediate slope, and becomes shorter at the intermediate slope. There is one problem regarding gender.

[Purpose of the invention]

The purpose of the present invention is to solve the problems of the prior art described above,
It is an object of the present invention to provide an escalator for transporting wheelchairs, etc., which can secure a wider and safer loading space.

[Summary of the invention]

In order to achieve this object, the present invention uses two adjacent steps as specific steps on which a wheelchair or the like is placed, and sets one of the specific steps to a reference frame portion, a tread portion, and a tread portion as a reference. Consists of a cross-link mechanism that connects and supports the frame so that it can move in the vertical and longitudinal directions, and allows the tread portion of one step to follow the tread portion of the other step in the vertical and longitudinal directions. It is characterized by having a means.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

@1 In the figure, 1 is a guide rail, 2 is a staircase for general passengers, and 3A and 3B are two specific adjacent and adjacent steps for loading wheelchairs, etc. One of the specific steps 3
A is divided into a reference frame part 4 and a footboard part 5, which are connected by a cross link mechanism 6. This cross link mechanism 6.

As shown in FIG. 2, two levers 8 and 9 are rotatably connected at the center by a bin 7, and the front end of one lever 8 is rotatably engaged with the bottom sK of the treadle part 5 from the bin IOK. The rear end is rotatably and movably engaged with the upper part of the reference frame part 4 by a guide roller 14 supported by the bin 11Vc and a guide groove 17 provided in the upper part of the reference frame part 4, and the other Both ends of the lever 9 can be similarly rotated and moved back and forth by guide rollers 15 and 16 supported by bins 12 and 13 and guide grooves 18 and 19 provided in the upper part of the reference frame part 4 and the lower part of the footboard part 5. Possibly engaged. Therefore, the footboard portion 5 is movable in one vertical direction and in the front-rear direction with respect to the reference frame portion 4 by this cross link mechanism 6. Further, a locking fitting 30 is provided at the upper part of the reference frame part 4, and a locking pin 31 is provided at the lower part of the footboard part 5, and by engaging these with each other, the reference frame part 4 and the footboard are connected. The part 5 is fixed in one piece and is used as a step for passengers. Furthermore, the tread on one step 3A! As shown in FIGS. 3 and 4, a storage hole 20 and a guide groove 21 are formed in the lower part of the housing hole 20 and a guide groove 21 that extend horizontally in the front-rear direction, and an engagement recess 2 is formed at the tip of these holes.
3 and its operating rod 24 are inserted, and a fixing nut 26 is screwed into the screw #25 of the operating rod 24. The other step 38 is formed with an engagement hole 27 that extends horizontally in the front-rear direction in the same manner as the storage hole 20, and also has a screw hole 28 that extends from the 1118 direction to this engagement hole 27. This screw hole is formed
A fixing bolt 29 is screwed together. Note that two or more sets of the above-mentioned cross link mechanisms and the engaging portions between the steps are arranged in parallel in the width direction of the escalator, that is, in the direction perpendicular to the plane of the paper.

Now, near the escalator entrance.

When the tread surfaces of two specific steps 3A and 3B are at the same height, the locking metal fitting 30 is rotated to release the locking pin from the locking pin, and as shown in FIG. As shown in Fig. 4, the engaging member 22 is moved forward by operating the operating rod 24 and inserted into the engaging hole 27, and the fixing bolt 29 is rotated to engage its tip in the recess 23 and further fixed. By rotating the nut 26 and press-fitting it to the lower side surface of the tread plate part 5, two specific steps 3A and 3B are connected with their respective tread surfaces held at the same height. When the escalator is operated in this state, as shown in Figure 1, at the % slope section,
There is a difference in level between the reference frame part 4 of one step 3A and the other step 3B, but the tread part 5 of one step 3A is at the same height as the tread surface of the other step 3B and is in a horizontal state. While holding the position, follow the other step 3B. At this time, the tread portion 5 of one of the three steps is displaced K by the same amount as the amount of protrusion of the other step 3B (to the side that is below the slope in the #r oblique portion).

In this way, the tread s5 of one step 3A can follow the tread portion of the other step 3B in the vertical and longitudinal directions, so that the change in the tread interval from the first entrance to the intermediate slope can be prevented. This allows a wider and safer loading space for wheelchairs, etc. to be secured.

In addition, in the embodiment described above, in order to make the tread portion of one step follow the tread portion of the other step in the vertical direction and the front-back direction, both steps are provided with engaging portions, respectively.
Instead of this retaining part, a push-up mechanism similar to the push-up mechanism in the known example may be provided to push up the tread part of one of the steps and make it follow the steps.

〔Effect of the invention〕

As explained above, according to the present invention, mutual K11IIi
Of two specific steps in contact, the tread surface of one step is kept parallel to the tread surface of the other step, and the tread portion of one step moves forward and backward by following the protrusion amount VC of the other step at the intermediate slope. The distance between the treads does not change because it can be followed upward while moving in the direction.

A wider and safer loading space for wheelchairs, etc. can be secured. Furthermore, while the tread section is always kept horizontal through the cross link mechanism, part of the load applied to the tread section is borne by the reference frame section, and the load applied to the tread surface of a specific step is evenly shared between both steps. Therefore, the mechanical strength of each of these steps may be comparable to that of general passenger steps.
