Description

The present invention relates to a door closing device for railway-related equipment used as a vehicle door or a platform door.

As a daily problem in railway companies, there are problems such as rushing into a vehicle and getting stuck in a vehicle door. If luggage is caught in the door of a railroad car, it may cause a train delay or lead to an accident. For example, as an example of train delay, a user intentionally puts an umbrella or a bag in a closing door to open the door, and then gets on a vehicle in the meantime. Further, if a white cane or a leg frame of a stroller is caught in the door, the door pinch detecting means cannot detect this, which may lead to an accident.

Conventionally, in order to solve such a problem related to baggage pinching, a technique for increasing the sensitivity of door pinch detection for detecting that a baggage is pinched has been proposed (see, for example, Patent Document 1). In recent years, the installation of platform doors has been promoted to prevent rush-in rides. Further, in recent years, railroad vehicles having a lintel portion of a passenger door provided with an indicator light that emits light when the door is opened and closed have been put into practical use. Further, as an old technique related to the present invention, a railway vehicle having an indicator light (called a vehicle side indicator light) on the side surface of the vehicle body for the commander or a staff member to confirm that the door is closed has been put into practical use.

Japanese Patent No. 5855440

In order to prevent the problem of luggage jamming on the door, it is effective to alert the user when opening and closing the door. By alerting with impact, it is possible to suppress acts such as intentionally pinching luggage between doors or rushing in. In addition, even if a baggage pinch that is difficult to detect occurs, the attention of the surrounding users can be directed to the occurrence of the baggage pinch by alerting the user or the staff in the vicinity of the door. Therefore, it can be expected that assistance will be provided so as not to lead to an accident, and that station staff and drivers will be approached.

In general, railway companies notify users of the opening and closing of doors by ringing a chime. However, since chimes are widely transmitted not only to passengers getting on and off railroad cars but also to the surroundings, there is a fact that chimes that have a great impact cannot be adopted.
In addition, when we examined a configuration in which light was emitted from the side of the vehicle body or the indicator light provided on the lintel of the door, it was found that it was difficult to alert the passengers of the vehicle with impact with this configuration. .. This means that the indicator light is installed away from the door so that the light emission is less likely to catch the eyes of passengers, and even if the light emission operation such as blinking is performed, the position is due to opening and closing rather than the fixed position light emission. It was thought that the cause was that the attention of passengers was concentrated toward the changing door.

An object of the present invention is to provide a door closing device for railway-related equipment that can call attention with impact when opening and closing a door.

In order to achieve the above object, the present invention
The door closing device for railway-related equipment

A light emitting body provided inside the cushioning material and capable of irradiating both one side and the other side of the boundary partitioned by the sliding door.
With
At least a portion of the cushioning material surrounding the luminous body is transparent or translucent.
The light emitter has a plurality of inward light emitting elements oriented in the direction from the outside to the inside of the railway vehicle, and a plurality of outward light emitting elements directed in the direction from the inside to the outside of the railway vehicle.
The plurality of outward light emitting elements are provided more than the plurality of inward light emitting elements.
The light emitting body is characterized in that light emission is controlled in conjunction with the control of the driving unit.
According to this configuration, the door end of the sliding door that opens and closes is provided with a light emitting body that irradiates light toward one side and the other side of the sliding door, so that it is easily noticed by the user passing through the door. , It is possible to obtain light emission whose position changes as the sliding door opens and closes. As a result, it is possible to encourage the user to call attention with an unprecedented impact.
Further, when calling attention at the door of a railway vehicle or a platform door, the light emission toward the home side requires a larger amount of light than the light emission toward the vehicle side. Therefore, according to the above configuration, by making the numbers of the inward light emitting elements and the outward light emitting elements different, it is possible to realize a required amount of light according to the irradiation direction without waste and extra control. it can.

Here, the door closing device for railway-related equipment according to the present invention is
A door pinch detection unit that detects that an object is caught in the sliding door,
A control unit that controls the drive unit based on an opening / closing command from the outside and a detection result of the door pinch detection unit.
With
The control unit reopens and closes the sliding door based on at least a standard opening pattern for opening the sliding door based on the opening / closing command, a standard closing pattern for closing the sliding door based on the opening / closing command, and detection by the door pinching detection unit. The drive unit can be controlled by a plurality of opening / closing patterns including a reopening / closing pattern.
The light emitting body may be configured so that light emission is controlled by any of a plurality of light emission patterns corresponding to the plurality of opening / closing patterns.

According to this configuration, the light emitting body emits light in conjunction with the opening / closing movement of the sliding door in a plurality of light emitting patterns corresponding to the plurality of opening / closing patterns including the standard opening pattern, the standard closing pattern, and the reopening / closing pattern. Therefore, the light emitted by the light emitting body, for example, prompts the user to give a strong warning when the sliding door is closed, and strongly notifies the surrounding users of the occurrence of an abnormality when a baggage is caught. Operation is possible.

Desirably, the plurality of emission patterns are emission patterns in which one or both of the emission color and the blinking pattern are different from each other.
A signal input unit for inputting a plurality of pattern signals for causing the light emitter to emit light in each of the plurality of light emission patterns is provided.
One of the plurality of pattern signals may be selected based on the control signal of the control unit and used for the light emission control of the light emitter.

According to this configuration, when the configuration of the light emitting body is later provided in the current door closing device, the light emission control of the light emitting body linked to the opening / closing pattern of the sliding door can be performed by diverting the current configuration as it is and changing the simple configuration. realizable. That is, a plurality of pattern signals for generating a plurality of light emission patterns are input to the signal input unit, some control signals of the control unit are taken out, and light emission control is performed using these to configure the control unit. The above light emission control can be realized without changing.

Further, the illuminant is arranged above the center of the sliding door.
A portion of the cushioning material containing the light emitting body and other portions may be integrated.
By providing the light emitting body inside the cushioning material, the degree of freedom in adjusting the hardness of the cushioning material may be reduced. On the other hand, as a measure against pinching doors such as white canes and stroller leg frames, the hardness of the cushioning material is increased at the lower part of the sliding door so that strong pressure is applied to the lower part of the cushioning material when the sliding door is closed. It may be set so that the distance between the and the contact partner is narrow. Therefore, if the illuminant is provided in a range where the hardness adjustment needs to be strictly set, there is a possibility that the hardness cannot be set well. However, in the above configuration, since the light emitting body is arranged above the center of the sliding door, it does not hinder the adjustment of the hardness of the cushioning material necessary for measures against pinching the door. In addition, since the part containing the illuminant and other parts are integrated, it is possible to prevent water from entering the vehicle through between these parts when washing the car, for example, in the case of a railroad vehicle door.

According to the present invention, it is possible to provide a door closing device for railway-related equipment that can call attention with an impact when opening and closing a sliding door.

In one slide member 13, the driving force of the driving device 14 is changed in the left-right direction by the direction changer 15 and transmitted, whereby the slide member 13 moves in the opposite direction to the other slide member 13. A pair of left and right sliding doors 11 are fixed to each of the two slide members 13, and the sliding doors 11 move in the opening / closing direction as the slide members 13 move.

The drive device 14 is provided with a door pinching detection unit 18 for detecting that something is pinched by the sliding door 11. The door pinch detection unit 18 performs the above detection by abnormally increasing the current of the motor that generates the driving force of the driving device 14, shifting the stop position of the door, and the like. The specific configuration of the door pinch detection unit 18 is not particularly limited, and for example, a piezoelectric sensor arranged at the door end of the sliding door 11 or an optical sensor arranged at the Kamoi portion of the sliding door 11 is adopted. You may. The arrangement of the door pinch detection unit 18 can also be changed in various ways according to the detection method. For example, when the door pinch detection is performed from the change of the control signal and the drive current, the door pinch is detected as a functional block in the control unit 21. The detection unit 18 can also be provided.

A cushioning material 31 is provided at the tip of the sliding door 11 from the lower part to the upper part. A light emitting body 32 is provided inside the cushioning material 31 above the cushioning material 31. Details of the cushioning material 31 and the illuminant 32 will be described later.
The drive current of the light emitter 32 is supplied from the switch 22 via the cable 23. The cable 23 extends, for example, over the upper edge of the sliding door 11 and the cable guide 24, and electrically connects the switch 22 and the light emitter 32. One end of the cable 23 is fixed to the sliding door 11 and moves left and right as the sliding door 11 opens and closes, but the middle part of the cable 23 moves along the cable guide 24, and the amount of slack can be increased or decreased at a predetermined position. It is bent and arranged like this. By routing the cable 23 in this way, the light emitting body 32 at the door end and the switch 22 can be electrically connected by the cable 23 without hindering the opening and closing of the sliding door 11.

The switch 22 takes in the power supply and the control signal from the control unit 21, and also inputs a pattern signal indicating the light emission pattern of the light emitter 32 from the outside. These signals are input via a plurality of signal input units of the switch 22. The control signals taken in from the control unit 21 include, for example, an open signal output when the sliding door 11 is opened based on the open command, a close signal output when the sliding door 11 is closed based on the close command, and a door pinch detection unit. The reopening / closing signal output when the sliding door 11 is reopened / closed based on the detection of 18 is included. The pattern signal may be generated by a separately prepared pattern signal generation device (not shown) and transmitted to each door closing device 1. For example, one pattern signal generation device may be provided in the leading vehicle or the trailing vehicle, and a plurality of pattern signals may be output in common to each door closing device 1 of each vehicle. The pattern signal includes a plurality of opening / closing patterns of the sliding door 11, such as a first pattern signal for lighting the light emitter 32 in green, a second pattern signal for blinking the light emitter 32 in red, and a third pattern signal for blinking the light emitter 32 in yellow. It is preferable that a plurality of pattern signals corresponding to each are included. The pattern signal generation device may be provided on each vehicle or each door.

The switch 22 generates a drive voltage of the light emitting body 32 from the power source taken in from the control unit 21, selects a pattern signal corresponding to the drive voltage based on the control signal taken in from the control unit 21, and uses the pattern signal and the drive voltage. Drives the light emitter 32 using. With such a configuration, when the configuration of the light emitting body 32 is later provided in the current door closing device, the light emitting control of the light emitting body 32 linked to the opening / closing pattern of the sliding door 11 can be performed by diverting the original configuration and making a simple change. realizable.

<Cushioning material and illuminant>
FIG. 2 is a plan view showing an upper end portion of the cushioning material of the embodiment. 3A and 3B are side views showing the cushioning material of the embodiment, FIG. 3A is a side view seen from one side, and FIG. 3B is a side view seen from the opposite side.
The cushioning material 31 is made of, for example, a plurality of types of rubber materials, and the upper portion 31a is made of a hollow tubular semitransparent material such as transparent or milky white that transmits light. The middle portion 31b and the lower portion 31c have a colored configuration that blocks light, such as black. The middle stage portion 31b has a configuration in which a soft rubber is embedded in a hollow hard rubber, and the lower stage portion 31c has a configuration in which a relatively hard rubber is embedded in a hollow hard rubber.
