Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator suitable for carrying a wheelchair or the like. 2. Description of the Related Art In today's modern day, which aims to improve the welfare environment, it is desired to adopt a specially designed transportation system or building structure so that a disabled person using a wheelchair can act relatively freely. ing. [0003] Recently, with the recognition that escalators are indispensable transportation in buildings, it is expected that escalators that can be easily used by persons with disabilities or elderly people with physical disabilities are inevitable. However, under the present circumstances, the installation angle and the driving speed which greatly affect the psychology of the escalator user do not feel any inconvenience to healthy people, but the aged and handicapped have agility when getting on and off. Escalators cannot be used due to lack of quality, and the installation angle is reduced for these people to increase stability when riding,
There have been proposed ones in which the operating speed is reduced to facilitate getting on and off. In addition, for people who have difficulty walking and use a wheelchair, there is a need for an escalator with special consideration so that the user can use it while on a wheelchair. [0005] Further, in department stores and the like, it was not possible to ride safely with the shopping cart on. This is because wheelchairs and carts have wheels and generally do not ride stably on steps with steps. Conventionally, there is an electric road which is generally called an electric road and has no steps on its tread portion. However, a drawback that the entire tread surface is inclined like a slide and the wheelchair is not stable, and the entire equipment takes a long distance and the space becomes longer. There was a disadvantage that the efficiency became poor. As a means for solving these drawbacks, a specific step is provided in a group of steps of a normal escalator as described in JP-B-56-41555, this specific step is stopped, and a wheelchair is used. After that, it has been proposed to restart and transport to the nearest floor. An example of using a large step is shown as an example of the specific step. However, when a large step is arranged, there is a problem that a large step is generated between adjacent steps. As one means for solving this problem, Japanese Patent Laid-Open Publication No.
No. 172376 has been proposed. According to this method, a specific step is provided between a general step and a part of the step that can move only in the vertical direction relative to the step, and the step that can be lifted by the specific step is crossed. Through a push-up mechanism consisting of a link and a push-up body, by using the operating rail of the push-up mechanism provided separately from the circulation path of the general steps, by pushing up to the same height as the tread of the adjacent general steps, The purpose is to secure a space for mounting a wheelchair or the like by expanding the area of the tread. [0010] Here, considering two adjacent steps, a general escalator is such that, near the entrance, the step surfaces of the adjacent steps have almost the same height. The width of the tread surface of the two adjacent steps is kept twice as large as the tread surface of one step. However, when these steps move to the slope, the tread plate surface height of each step relatively changes, and at the same time as the change in the height direction, the front (the side of the slope that is above the slope).
The rear (opposite side of the front) end of the step located at
It relatively protrudes toward the step side located behind. For this reason, in the inclined portion, the horizontal distance between two adjacent steps is reduced by the amount of the protrusion. According to the above-described known example, a part of the tread surface is moved only in the vertical direction relative to the step, so that the rising step plate is moved so that the two steps do not interfere with each other. It is reduced by an amount corresponding to the amount of protrusion. Further, a mounting space for a wheelchair or the like constituted by a step on which a part of the step board rises and a step adjacent to the front of the step is provided between the two steps and the step adjacent to the step further adjacent to the front. By protruding on the slope,
The width of the effective plane for loading a wheelchair, etc., obtained by keeping the tread surfaces of two steps at the same height, is twice as large as the width of the tread surface of one step, and it is described above. This is the area obtained by subtracting the area equivalent to twice the amount. Further, according to the above-mentioned known example, the interval between the treads of the two steps for holding a mounting space for a wheelchair or the like changes between the entrance / exit and the intermediate inclined portion, and becomes shorter at the intermediate inclined portion. There is a problem with respect to safety. Further, according to the above-mentioned known example, in order to convert the existing escalator into a transportable escalator such as a wheelchair, at least a rail for operating the push-up mechanism needs to be provided at least in the middle of the upper side of the escalator on the outward path side. There is a problem that it is necessary to lay the entire inclined portion, and this remodeling involves difficulty and the structure is extremely complicated. Therefore, an object of the present invention is to provide an escalator for transporting a wheelchair or the like that can secure a wider and safe mounting space by adding a very simple structure to existing ones as well as newly manufactured ones. Is to provide. In order to solve the above problems, the present invention comprises a plurality of steps connected endlessly, and at least one of these steps is used as a reference frame. And a tread portion that rises with respect to the reference frame portion to form a wheelchair mounting surface, and the ascending tread portion

Step, for example, the ascending step portion of the step adjacent to the upper step
State that each tread surface is held at the same height on the tread plate
In coupling engagement element, in an escalator for transporting provided wheelchair or the like connecting means made of the engaging hole, one end
To the reference frame and the other end to the ascending tread.
Re respectively attached, a mechanism for movably water earnestly maintain treadle portion where the rising direction back and forth with respect to the reference framework part,
For example, one end of the two levers on the reference frame side and one
The end of the lever on the side of the tread portion is movable in the front-rear direction,
The end of the other lever on the side of the tread portion is shifted in the front-rear direction.
By providing a cross link mechanism attached so as not to move, the tread surface of the ascending tread portion is always kept horizontal with the tread surface of the step adjacent to the upper stage, and the ascending tread portion at the middle inclined portion is It moves in the front-rear direction with respect to the reference frame, and together with the tread of the step adjacent to the upper step, secures a wider and safer mounting space for wheelchairs, etc. The present invention is characterized in that not only the steps adjacent to the steps but also the steps composed of the ascending step plate portion and the reference frame portion are shared. FIG. 1 is a block diagram showing an embodiment of the present invention.
4 will be described. In FIG. 1, 1 is a guide rail, 2 is a general passenger step, and 3A and 3B are two adjacent specific steps for mounting a wheelchair or the like. Among the specific steps, one step 3A is divided into a reference frame portion 4 and a tread portion 5, and these are connected by a cross link mechanism 6. This cross link mechanism 6 moves the tread plate 5 with respect to the reference frame 4.
To maintain a horizontal mechanism so that it can be moved in the front-rear direction
As shown in FIG. 2, the center portion is composed of two levers 8 and 9 rotatably connected by a pin 7, and the front end of one lever 8 is rotatable below the tread plate portion 5 by a pin 10. A guide roller 1 engaged with a rear end supported by a pin 11
4 and a guide groove 17 provided on the upper part of the reference skeleton part 4 are rotatably and movably engaged with the upper part of the reference skeleton part 4, and both ends of the other lever 9 are pins 12, 1.
3 and guide grooves 18, 1 provided above the reference frame 4 and below the tread 5.
9, it is similarly rotatably and movably engaged. Accordingly, the tread portion 5 is provided with the cross link mechanism 6.
Thereby, it can be moved in the up-down direction and the front-back direction so as to always keep the horizontal state with respect to the reference frame portion 4. A locking bracket 30 is provided on the upper part of the reference frame 4 and a locking pin 31 is provided on the lower part of the tread 5, and the reference frame 4 and the tread are engaged with each other. 5 is integrally fixed and used as a step for general passengers. Further, the tread portion 5 is moved upward to form a wheelchair mounting surface,
That is, the tread surface is the same as the tread surface of the step 3B adjacent to the upper step.
As means for holding at the same height position, as shown in FIGS. 3 and 4, a storage hole 20 and a guide groove 21 extending horizontally in the front-rear direction are formed at the lower part of the tread portion 5 in one step 3A. At the same time, an engaging element 22 having an engaging concave portion 23 at the tip and an operating rod 24 thereof are inserted into them, and a fixing nut 26 is screwed into a screw portion 25 of the operating rod 24. In the other step 3B, an engaging hole 2 which also extends horizontally in the front-rear direction is provided at a position corresponding to the storage hole 20.
7, and a screw hole 28 extending from the side to the engagement hole 27 is formed, and a fixing bolt 29 is screwed into the screw hole 28. In addition, two or more sets of the above-mentioned cross link mechanism and the engaging portion between the steps are arranged in the width direction of the escalator, that is, in the direction perpendicular to the paper surface. Now, when the tread surfaces of the two specific steps 3A and 3B are at the same height in the vicinity of the entrance of the escalator, the locking fitting 30 is rotated to release the engagement with the locking pin, and As shown in FIG. 3 and FIG.
The operation of step 4 moves the engaging element 22 forward to move the engaging element 27 to the engaging hole 27.
And the fixing bolt 29 is rotated to engage the tip thereof with the concave portion 23, and the fixing nut 26 is further rotated and pressed against the lower side surface of the tread plate portion 5, whereby the two specific steps 3 A, 3 B Are connected in a state where the respective tread surfaces are kept at the same height. When the escalator is operated in this state, as shown in FIG. 1, a step is generated between the reference frame 4 of the one step 3A and the other step 3B in the inclined portion, but the step 5 of the one step 3A is formed. Follow the other step 3B at the same height as the tread surface of the other step 3B and while keeping the horizontal state. At this time, one step 3
The tread portion 5 of A is displaced rearward (to the side of the inclined portion below the slope) by the amount of protrusion L of the other step 3B. In this manner, the tread portion 5 of one step 3A can follow the tread portion of the other step 3B in the up-down direction and the front-back direction, so that the tread portion from the entrance to the middle inclined portion can be obtained. There is no change in the interval, and a wider mounting space for a safe wheelchair or the like can be secured. When a wheelchair or the like is mounted, the load is applied to the tread surfaces of both steps 3A and 3B.
In addition to the other step 3B to which the step board is fixed, the load applied to the step face can be shared via the cross link mechanism 6 not only in the one step 3A but also the load of the wheelchair or the like by the both step faces. It is possible to share the wheelchair and the like stably in a well-balanced manner. As described above, according to the present invention,
It comprises a plurality of steps connected endlessly, and at least one of the steps comprises a reference frame portion and a step plate portion which rises with respect to the reference frame portion to form a wheelchair mounting surface. And the ascending tread portion is mounted on the wheelchair.
In an escalator for transporting a wheelchair or the like provided with a means for holding at a raised position forming a surface , one end side is the reference
The other end side is attached to the ascending tread plate part on the frame part.
Vignetting, by providing a mechanism for maintaining movably water earnestly in the longitudinal direction with respect to the rising step board portion the reference framework part, step board surface of the step of the adjacent step plate surface of the tread plate portion in which the rise in the upper And always kept horizontal, and the ascending tread portion at the intermediate inclined portion is moved in the front-rear direction with respect to the reference frame portion, so that the ascending tread portion is together with the tread of the step adjacent to the upper stage. A wider and more secure mounting space for a wheelchair or the like can be secured, and when a wheelchair or the like is mounted, the load is reduced not only by the tread surface of the step adjacent to the upper stage but also by the tread surface of the rising tread portion. Machine that keeps it horizontal so that it can move in the front-rear direction.
Since the load is shared via the structure , the load of the wheelchair and the like can be reliably shared by the two tread surfaces in a well-balanced manner, and the wheelchair and the like can be stably transported. Further, the existing general escalator can be modified into an escalator capable of carrying a wheelchair or the like by a very simple modification.
