Abstract

The present invention provides a smart step escalator comprising: a step frame having a detachable step plate provided on the upper side; a lifting member provided on the left and right sides of the step frame, respectively, which supports the left and right sides of the step plate and selectively extends in length to raise the step plate from the step frame; a driving means provided on the left and right sides of the step frame, respectively, which rotates to a corresponding rotation angle by external pressure to lift a part of the lifting member and extend the length of the lifting member; and a guide rail positioned on the path of movement of the step frame when raising of the step plate is required, which guides the driving means to rotate to a corresponding rotation angle. By using only mechanical elements without electric/electronic driving means such as a motor or actuator, the step plate of the escalator can be selectively raised to 1 or 2 levels, offering excellent cost competitiveness in terms of processing, assembly, and installation, and allowing strollers, wheelchairs, etc. to be stably boarded onto the escalator step as three step plates are maintained at the same height.

Description

Smart Step Escalator The present invention relates to a smart step escalator, and more specifically, to a smart step escalator in which, when entering an inclined path based on one of the first steps among a plurality of steps moving along a diagonal step chain, the step of the second step following the first step rises by one step and the step of the third step following the second step rises by two steps, so that the three step steps are maintained at the same height, thereby allowing strollers, wheelchairs, etc. to board. Generally, escalators used as passenger transport devices are installed between floors or in long corridors of buildings with high pedestrian traffic to continuously transport people. In particular, these escalators are installed and operated as transfer structures for general users, as well as the disabled and the elderly, in areas where passengers transfer to other modes of transportation, such as transfer passages within subway or train stations, or at station entrances and exits. The escalator described above is configured to include a truss installed embedded within the building and a pair of side support frames installed on both upper sides of the truss, wherein landing sections are formed at both ends of the truss, and a drive motor, a step chain, and a pair of gears supporting the step chain to enable travel are installed inside the truss, and a plurality of steps are connected to the step chain. And as mentioned above, a handrail is installed on the upper part of each of the pair of side support frames so as to move at the same speed as the step, and this handrail is driven by a drive motor that drives the step chain. However, since the escalator according to the conventional technology described above features stepped steps on the inclined section, there is no problem for the general public even if they are loaded onto the steps; yet, for users utilizing mobility aids such as strollers and wheelchairs, there are difficulties in the structure for loading strollers and wheelchairs onto the escalator. As a solution to overcome the aforementioned problem, a wheelchair mounting structure according to the prior art is used, which utilizes a bogie that moves up and down in an inclined direction by means of an inclined guide on a wall inside a station where an escalator device is installed separately from the escalator. However, since a bogie must be provided separately from the escalator, there is a problem in that installation is not easy. To resolve the aforementioned problems, wheelchair-accessible escalators were conventionally provided in Japan. When a wheelchair user presses the button on this escalator, the three escalator steps rise while maintaining the same height. This enables wheelchair users to use the escalator. However, a disadvantage of this product is that there is only one connected step module in the entire line, so it can only be used once per cycle, and there is a limitation that more than two wheelchairs cannot be boarded at the same time. For example, if the step for that function is located in the middle of the escalator, you must wait until this step comes down. This causes significant inconvenience to wheelchair users and those using strollers. In addition, since it is implemented using separate actuators for each step, it is less economical. In addition, Korean Registered Patent No. 10-1644622 (July 26, 2016), titled "Escalator device for disabled persons with a 3.5-step structure," was proposed; however, the aforementioned prior art is characterized by the fact that two steps on the rear side of a reference step are raised through solenoid operation, and the angle of the last step is adjusted to provide safety to wheelchair or stroller users. However, this conventional technology also has the disadvantage of being less economical because it utilizes a separate actuator.
