Abstract

The creation department provides a hand-held ladder anti-pinch device, which is connected with an anti-pinch device disposed at the corner of the escalator at the escalator control device, and the switch assembly of the anti-pinch device can be used to warn the user in advance of dangerous behavior, such as The head and the hand extend out of the handrail of the escalator to avoid accidents. When the user touches the pre-established switch assembly, the anti-pinch device sends a warning signal to the control device, and the drive motor decelerates to slow down the escalator and make the warning light When the light is on, the buzzer sounds a warning to warn the user that the behavior is dangerous. When the user continues the dangerous behavior and touches the stop switch of the switch component that is connected, the anti-trap device sends a stop signal to the control. The device drives the motor to stop, causes the stop light to illuminate, and the escalator stops to prevent disasters and ensure user safety.

Description

Walking ladder anti-pinch device

The present invention relates to an anti-pinch device, in particular to an anti-pinch device for an escalator, which can prevent the occurrence of disasters by sensing whether the user is in a dangerous state to control the escalator to slow down, warn or stop the escalator. And to protect the safety of users.

With the advancement of technology, human beings are not committed to creating a better and more comfortable living environment. Therefore, department stores, shopping malls, commercial buildings, exhibition venues, MRT stations, railway stations, high-speed rail stations and airports all have hands. The escalator makes it easy for people to go up and down the stairs.

The escalator is convenient, but there are also dangerous areas, that is, between the upper and lower escalators or between the escalator and the wall. When the user rides the escalator, the head is placed against the handrail or the hand. Stretching out of the armrest, if you forget to return to the armrest, you will accidentally catch your head or hand. At this time, if you do not stop the escalator immediately, it may cause a major accident to the user, resulting in irreparable regret. .

At present, although there are regulations, it is necessary to set a "caution chuck" warning sign at the corner, but there are still accidents involving pincers, such as the Beijing Railway Station shopping plaza on December 20, 2009 at the Taipei Station shopping district. The escalator chuck event, the 10-year-old girl who was pinched to the head, had a fracture of her left face, a depression, and a cheek on her cheek; on August 22, 2018, Taichung City Guangsan SOGO Department Store There was also an accident in which the escalator pinched the person and caused the girl's neck to be pinched by the handrail and ceiling. At present, although each escalator has an emergency stop button, because the setting position is different, and not everyone knows the position of the emergency stop button setting, it takes time to find and find and activate the emergency stop button when an accident occurs. It’s too late to stop the accident.

It can be seen that the safety of the above escalators is still lacking and needs to be improved.

In view of the shortcomings derived from the above problems, the creators of this case have improved and innovated, and after painstaking research, they have successfully developed and completed the escalator anti-trap device.

The main purpose of this creation is to provide a hand-held ladder anti-pinch device, which is used in conjunction with the escalator. When the user has dangerous behavior (such as putting the head and hands out of the handrail of the escalator), the warning of the switch component of the anti-pinch device is used. Function, the first stage is to slow down the operation speed of the escalator and provide an audible and visual warning signal to alert the user. If the dangerous behavior continues, the second stage warning function of the anti-pinch device will be performed, and the escalator will be controlled to stop operation. It can provide sound and light warning signals to alert users to the danger zone. The above two-stage warning function can provide users with sufficient reaction time to avoid injury before the accident occurs to ensure user safety.

The technical means used for the above purpose is a walking ladder anti-pinch device, which is connected to an escalator, the anti-pinch device is connected to one of the escalator control devices, and includes a switch component and is connected to the switch assembly. a warning device and a stop device, the switch component is installed at an angle of the escalator, and includes a warning switch and a stop switch; when the user has a dangerous behavior, the warning switch is touched, the warning switch and the The warning device is turned on, and the warning device sends a warning signal to the control device to decelerate the escalator; if the dangerous behavior is continued, the shutdown switch is then touched, and the shutdown switch is electrically connected to an immobilizer, and The shutdown The device sends a shutdown signal to the control device to stop the escalator.

The switch assembly further includes a warning component, and the warning switch and the stop-opening relationship are micro-switches, and the dangerous behavior touches the warning component, and the warning component contacts the warning switch or the shutdown switch, so that the warning component contacts the warning switch or the shutdown switch The warning switch or the stop switch turns on the corresponding alarm or the stop device.

The switch assembly further includes a warning component, and the warning switch and the stop-opening relationship are touch switches, and the dangerous behavior touches the warning component and causes the warning component to contact the warning switch or the shutdown switch, so that the switch component The warning switch or the stop switch turns on the corresponding alarm or stop.
