Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an escalator equipped with a special step device that can be used by wheelchairs, strollers, etc.

(Prior Art) With the development of transportation systems, railway station platforms and the like have come to be installed higher or lower than the ground. Along with this, an increasing number of stations have been installing escalators to facilitate the convenience of passengers.

(Problem that the invention aims to solve) However, the steps for passengers to ride on are wide and have a width of 1
Generally, it is approximately 40 cm deep. Therefore, wheelchairs and baby strollers cannot be placed horizontally on the platform, and must be used by leaning over two steps, which is extremely dangerous.

On the other hand, some places have escalators specifically for wheelchairs, but they have the disadvantage of having to be installed separately from escalators for general use vehicles.

The present invention was made in order to solve the above-mentioned drawbacks, and aims to provide an escalator that allows wheelchair users and stroller users to move between floors of a building using an escalator that is used by general users. The purpose is

[Structure of the idea]

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a specific step that is maintained horizontally at least 2.5 steps or more for placing a wheelchair, etc., and a step that can be engaged with this specific step. A step engaging device, a cart on which the step engaging device is mounted and front wheels and rear wheels arranged on both sides thereof, a cart lifting device arranged at the bottom of the cart to raise and lower the cart, and front wheels and rear wheels of the cart. and a guide rail that guides the steps and maintains the specific steps horizontally.

(Function) In the present invention, during normal operation, the above-mentioned specific step does not engage with the step engaging device, and the specific step operates in the normal state.On the other hand, when a user in a wheelchair etc. It acts like. That is, the cart is raised by driving the cart lifting device, whereby the specific step and the step engaging device are engaged, and when the escalator is started, the front wheels and rear wheels of the cart are guided by the guide rail, The above-mentioned specific step always moves while maintaining it in a horizontal state.

(Example) The following is an example of the present invention in Figures 1 to 3.
This will be explained with reference to the figures. In the figure, 1 is a trolley, and this trolley 1 has a step engaging device 2 that engages with a specific step in order to place a wheelchair or the like on it and maintain the step horizontally.
It is equipped with Front wheels 3 and rear wheels 4 are arranged on both sides of this truck 1, respectively. Steps 5, 6,
7 is provided with an engaging piece 8, which engages with the engaging device 2 of the truck 1. The steps 5 are nested and can be freely divided into 5a and 5b in the front and rear from the middle. The step 7 has a cleat riser 9 that is more than twice as long as a normal step, a front wheel 10 and a rear wheel 1.
The step cleat 13 includes a frame 12 and a step cleat 13, which are integrally connected to each other.

Further, at the bottom of the truck 1, a truck lifting device 14 (for example, a hydraulic cylinder and its drive unit) for raising and lowering the truck 1 is provided.

On the other hand, after the cart 1 and the steps 5b, 6, 7 are engaged by the step engaging device 2, the cart 1 must always maintain the steps 5b, 6, 7 horizontally in accordance with the movement of the step 6. For this purpose, guide rails 15 and 16 for guiding the front wheels 3 and rear wheels 4 of the truck 1 are provided so as to be supported on both sides of the truss 17, respectively, and furthermore, the ends 18 of the upper and lower floors of the guide rails 15 and 16, Reference numeral 19 indicates that the trolley 1 is moved by the trolley lifting device 14.
It is configured to be separable from the guide rails 15 and 16 so as to move up and down together. Further, the skirt guards 20 on both sides of the step are configured to have a high height so that even when the step 7 is in a horizontal state with the step 6 at the intermediate part, there is no gap between the handrail 23 and the step 7.

Next, the operation of the above embodiment will be explained. During normal operation, the trolley 1 does not engage with the steps 5b, 6, 7, and descends into the truss 17 of the escalator. When a user of a wheelchair or the like gets on, first, specific steps 5b, 6, and 7 are stopped at predetermined positions of the entrance where they can engage with the trolley 1. After the steps have stopped, the cart lifting device 14 is driven to raise the guide rails 18 and 19 that are lowered together with the cart 1 during normal operation, and then the step engaging device 2 provided on the cart 1 moves the cart 1 to the steps. 5b, 6, and 7, and at the same time, the engagement between 5a and 5b of the step 5 and the engagement between the step 7 and its frame 12 are released.

When the escalator is started after a wheelchair or the like gets on board, the trolley 1 is guided by the guide rails 15, 16 together with the engaged steps 6, and then steps 5b, 6, 7.
Move while always keeping it horizontal. Then, the escalator is stopped at a predetermined position where the trolley 1 at the exit and the steps 5b, 6, and 7 can be disengaged.

After the steps stop, drive the trolley lifting device 14 on the exit side to place the trolley 1 together with the trolley 1 on the guide rail 1.
5, 16 are divided guide rails 18, 19
is lowered, and at the same time steps 5b, 6, and 7 are disengaged, steps 5a and 5b, step 7, and its frame 1 are lowered.
Re-engage 2.

After the wheelchair, etc. gets off, normal escalator operation resumes. When using such a wheelchair, driving is performed manually or automatically.

[Effect of idea]

According to the present invention, users such as wheelchairs can be easily and safely transported by the same escalator as general users without providing separate equipment for users such as wheelchairs.
