Description

{PLATFORM SCREEN DOOR WITH EMERGENCY ESCAPE FUNCTION CONSTITUTED TO INSTALL ADVERTISEMENT PANEL}

The present invention relates to a platform screen door, and more specifically, to a platform screen door that functions as a wall to prevent passengers from falling onto subway tracks while having an advertisement board installed thereon, while being configured to open in an emergency to allow passengers to evacuate, and to enable the installation of an advertisement board.

In the case of electric trains such as subways or light rail, platforms are installed along with the tracks for passengers to board and disembark.

Screen doors are installed on the above platforms to prevent passengers from falling onto the tracks due to their carelessness and to prevent dust from entering when the train is in operation.

The above screen door is configured to slide left and right in connection with the door of the electric train, so that it opens when passengers get on and off after the electric train stops, and closes while the electric train is in motion.

The above screen doors are gradually being installed more and more as they solve passenger safety issues and improve cooling and heating efficiency on the platform.

Since the above screen door is installed so as to face the door section of the electric car, it is installed at the same interval as the interval between the doors of the electric car.

In addition, a fixed wall including transparent glass is installed in the area between the parts where the above screen doors are installed. Recently, billboards for commercial advertisements are frequently installed in the above fixed wall parts.

However, in the event of a breakdown or accident of the electric train, there may be cases where the door of the electric train may not stop so as to face the screen door position exactly.

As described above, if the door part of the electric train does not stop so that it faces the position of the screen door exactly, there is a problem in that passengers inside the electric train cannot get out through the electric train door and the screen door.

In particular, when a billboard is installed on a fixed wall between screen doors, there is a problem in that the billboard obscures a portion of the fixed wall, making it more difficult for passengers inside the train to evacuate.

To solve these problems, the applicant of the present invention applied for a patent on July 18, 2016 for the invention titled “Elevator screen door forming an emergency door that also functions as a billboard” and received a registration decision (Registration No. 10-1681603).

In the above patent application, a configuration is disclosed in which the part where the billboard is installed is configured as a screen door that slides left and right, thereby allowing passengers to evacuate by opening the screen door where the billboard is installed in an emergency.

However, the above patent application includes configurations that operate the screen door using a motor, but there is a problem in that the configurations interfere with the operation of the screen door when the motor does not operate, such as in the event of a fire on the platform.

Referring to FIGS. 1 to 5, a platform screen door configured to enable emergency escape and billboard installation according to the present invention includes an upper rail member (10) installed on a subway platform, a lower rail member (20) installed on the floor of the platform, and a door member (30) installed to slide left and right along the upper rail member (10) and the lower rail member (20), and an advertisement board (100) is arranged on the front side of the platform side of the door member (30), and the door member (30) includes a panic bar member (40) installed horizontally on the back surface of the door member (30), a panic bar linkage locking member (50) that moves downward by the operation of the panic bar member (40), and a force transmitted to the panic bar member (40) to the panic bar linkage locking member (50). A locking driving part (60) is included, and a locking interference part (70) for interfering with or releasing interference from the locking driving part (60) is installed on both sides of the upper rail member (10), a door opening switch (80) is installed on the back surface of the door member (30), and a switch interference part (90) is installed at a position facing the door opening switch (80), the door opening switch (80) is formed in a cylindrical shape with a circular cross-section, and an inclined surface is formed at the upper end, and the switch interference part (90) is formed convexly toward the door opening switch (80), and when the panic bar member (40) is operated so that interference between the panic bar linkage locking part (50) and the locking interference part (70) is released and the door member (30) moves in the left-right direction, It is characterized in that the door opening switch (80) is configured to generate a door opening signal by interference by the switch interference member (90).

The platform screen door having the emergency door function according to the present invention is installed in the space between screen doors (200) installed to correspond to the door positions of an electric train on a subway platform.

When the above screen door (200) is referred to as an existing screen door, the existing screen door (200) is installed between pillars (250) installed on the subway platform so as to correspond to the door position of the electric train.

In this state, the platform screen door having the emergency door function according to the present invention is installed on the pillars (250) between the existing screen doors (200) and protrudes somewhat toward the platform.

Based on Fig. 2, the upper space of the screen door (200) is the track on which the electric train runs, and the lower space is the platform area where passengers wait for the electric train.

The elevator screen door having the emergency door function according to the present invention normally functions as a wall with an advertisement board (100) installed on the front.

And, in case of an emergency, such as an emergency stop of an electric vehicle, it is configured to be opened by sliding left and right as needed.

As described above, in order to slide the screen door according to the present invention in the left and right directions in FIGS. 1 and 2, the upper rail member (10) is installed between the pillars (250).

At this time, the upper rail member (10) is installed so as to protrude slightly toward the platform between the pillars (250).

And, the lower rail member (20) is installed at the lower part facing the upper rail member (10).

The lower rail member (20) is installed on the floor of the platform below the upper rail member (10), and the lower rail member (20) is also installed so as to protrude slightly from the pillars (250) toward the platform.

The door member (30) can slide left and right along the upper rail member (10) and lower rail member (20) installed as described above in FIGS. 1 and 2.

The above door member (30) is formed into a rectangular shape that is long in the horizontal direction, and an advertisement board (100) is fixedly installed on the front side of the platform.

On the back surface of the door member (30), a panic bar member (40) is installed to enable a passenger of the electric vehicle to open the door member (30) horizontally in an emergency.

The above panic bar member (40) is formed in a long horizontal bar shape so that a passenger can easily hold it and push it toward the door member (30).

The above panic bar member (40) is installed in multiple numbers in a horizontal direction on the back surface of the door member (30), i.e., on the track side of the electric vehicle, and the multiple panic bar members (40) are configured to be interconnected.

Thus, when one of the panic bar members (40) is held and pushed toward the door member (30), rotational force is transmitted to the locking drive member (60).

The above panic bar member (40) is positioned to protrude slightly toward the electric train tracks in normal times, and when a person pushes the panic bar member (40) toward the door member (30), the rotational force resulting from such manipulation is transmitted to the locking drive unit (60).

Referring to FIGS. 4 and 7, the rotational force generated by manipulating the panic bar member (40) is transmitted to the locking driving unit (60) and configured to move the link bar (64) connected to the locking driving unit (60) downward.

A panic bar linkage locking part (50) is coupled to the upper part of the above link bar (64), and the panic bar linkage locking part (50) can also be moved downward by the link bar (64) that moves downward as described above.

As shown in Fig. 7, a support spring (66) is installed on the upper portion of the link bar (64), and the panic bar linkage locking part (50) is configured to always protrude upward by the support spring (66).

That is, when no force is applied to the panic bar member (40), the panic bar linkage locking part (50) is configured to protrude upward by the support spring (66), and when a pushing force is applied to the panic bar member (40), the panic bar linkage locking part (50) is configured to move downward by overcoming the spring force of the support spring (66).

In addition, a locking interference unit (70) for interfering with or releasing interference from the panic bar interlocking unit (50) is installed on the side of the panic bar interlocking unit (50).

As shown in Fig. 3, the locking interference part (70) is installed on both side ends of the upper rail member (10).

And, the panic bar linkage locking part (50) is configured to be located on the outside.

Thus, when no force is applied to the panic bar member (40), the panic bar linkage locking member (50) protrudes upward and interferes with the locking interference member (70), thereby preventing sliding movement of the door member (30).

However, when a force is applied to the panic bar member (40) and the panic bar linkage locking member (50) moves downward, the door member (30) can slide left and right because it is not interfered with by the locking interference member (70).

As shown in Figures 5 to 7, the panic bar locking part (50) is formed in a cylindrical shape with an overall circular cross-section, and an inclined surface is formed at the upper end (54).

That is, the body (52) of the above-mentioned panic bar locking part (50) is formed in a cylindrical shape with a circular cross-section, and its upper part (54) is formed in a trapezoidal cross-section shape on the side cross-section, so that the diameter can be formed in a shape that gradually decreases as it goes upward.

Meanwhile, the locking interference portion (70) is formed as a flat shape having a predetermined thickness overall, but the side cross-section is formed to have a long rectangular shape.

That is, when the direction shown in Fig. 7 is determined as the front view direction of the locking interference part (70), the side view not shown in Fig. 7, that is, the side view in the direction horizontal to the paper surface, is formed to have a long rectangular shape.

And, on the side of the locking interference part (70) facing the panic bar linkage locking part (50), a vertical surface (74) is formed based on the front view, and on the opposite side, an inclined surface (72) is formed.

In this state, as shown in Fig. 7, the panic bar locking part (50) is configured to be placed on the outer side (left side) of the vertical surface (74).

And, as shown in Fig. 3, the panic bar linkage locking part (50) installed on the right end of the upper rail member (10) is placed on the outer side (right) of the vertical surface (74) of the locking interference part (70) installed on the right end of the upper rail member (10).

Thus, in normal times when no force is applied to the panic bar member (40), the body part (52) of the panic bar linkage locking member (50) is interfered with by the vertical surface (74) of the locking interference member (70), so that the door member (30) cannot slide.

However, when the door member (30) is returned to its original position after the panic bar member (40) is manipulated to slide in the left or right direction, the inclined surface portion formed at the upper end (54) of the panic bar linkage locking member (50) comes into contact with the inclined surface (72) portion of the locking interference member (70).

Thus, the panic bar locking part (50) is configured to move downward while deforming the support spring (66) by the weight of the door member (30) itself and the action between the two inclined surfaces (54, 72).

And, when the panic bar linkage locking part (50) returns to its original position by passing the locking interference part (70), the panic bar linkage locking part (50) is moved upward again and protruded by the support spring (66).

With this configuration, when it is desired to slide the door member (30) from its initially installed position, the panic bar member (40) must be pushed, but when it is desired to return the moved door member (30) to its original position, it is configured so that there is no need to manipulate the panic bar member (40).

As shown in Figures 3 and 5, a plurality of rollers (2) are installed inside the upper rail member (10).

The above plurality of rollers (2) are installed so as to be firmly fixed within a roller frame (4) made of metal, and the roller frame (4) is fixed to the upper surface within the upper rail member (10) by a bolt (5).

The above roller frame (4) is solidly constructed of a metal material such as steel or stainless steel.

And, as shown in FIGS. 8 and 9, adjacent roller frames (4) can be configured to be connected to each other by roller frame connecting members (6).

The above roller frame connecting member (6) is formed in the shape of a band having a predetermined thickness using a metal material such as steel or stainless steel.

And, with the locking interference part (70) coupled to the side of the roller frame (4), the upper surface of the locking interference part (70) is fixed to the upper surface inside the upper rail member (10).

Thus, in a state where the roller frame (4) and the locking interference part (70) are connected and fixed to each other, both the roller frame (4) and the locking interference part (70) are fixed to the upper rail member (10), thereby forming a very strong joint configuration.

And, a door rail member (32) is installed and joined to the upper part of the door member (30).

As shown in Fig. 5, the door rail member (32) is formed of a metal material having a constant cross-section along the longitudinal direction and is arranged over the entire length of the upper portion of the door member (30).

The above door rail member (32) can be formed of, for example, aluminum or an aluminum alloy.

The above door rail member (32) is placed inside the upper rail member (10), and the lower part of the door rail member (32) is connected to the upper part of the door member (30).

And, an opening (34) is formed along the entire length of the door rail member (32) at the upper end of the door rail member (32), and a bolt (5) for connecting the roller frame (4) passes through the opening (34).

In this state, the two side portions of the opening (34) of the door rail member (32) are configured to be supported by the roller (2).

A reinforcing portion (36) may be formed to protrude from the side of the roller support portion (342) supported by the roller (2) in the door rail member (32).

By reinforcing the portion where the roller support portion (342) and the body portion of the door rail member (32) meet, i.e., the portion where they meet at an angle of approximately 90 degrees in cross section, with the reinforcing portion (36), it is possible to prevent the area around the roller support portion (342) from being damaged due to stress being concentrated at the portion where they meet.

As described above, the door rail member (32) is formed of a metal material having a constant cross-sectional shape along the longitudinal direction, and is supported by the rollers (2) while being arranged over the entire length of the upper portion of the door member (30), thereby increasing durability and operational reliability.

That is, if the rollers are installed on the upper part of the door member (30) and configured to slide along the upper rail member (10), the rollers must rotate while moving, and thus the rotational force must be supported along with the impact force applied during the roller movement process.

However, as in the present invention, the rollers (2) are installed in a fixed position, and a metal door rail member (32) is installed along the entire length of the upper portion of the sliding door member (30), so that the door member (30) slides by the rollers (2), so that the rollers (2) are not subject to impact force as they move.

Therefore, compared to the case where the door member (30) is moved with rollers installed on the door member (30) side, durability can be increased and operational reliability can be maintained even during long-term operation.

Meanwhile, as shown in Fig. 10, the portion of the roller frame connecting member (6) that is connected to the roller frame (4) is connected in an overlapping state using a connecting means (604) such as a bolt and nut.

At this time, the connecting means (604) is connected to the overlapping portion as described above with the buffer member (608) interposed therebetween.

The above-mentioned buffer member (608) is formed of an elastic synthetic resin material such as rubber and is configured to buffer vibration and impact applied to the joint portion.

And, as shown in FIGS. 9 and 10, a horizontal hole (606) may be formed in the portion of the roller frame connecting member (6) where the connecting means (604) is connected.

Thus, when vibration and impact are applied, the shaft (bolt shaft) portion of the coupling means (604) is somewhat displaced horizontally along the hole (606) portion to provide a buffering effect, so that damage from external impact can be prevented compared to when the coupling means (604) is coupled so as to be very firmly fixed in position.

Meanwhile, in another embodiment of the present invention illustrated in FIG. 11, the roller (2) is formed of a synthetic resin material, and concave portions (202) are formed along the circumferential direction of the roller on the surface of the roller (2) that comes into contact with the roller support member (342).

And, on the surface of the roller support portion (342) of the door rail member (32) that comes into contact with the roller (2), concave and convex portions (344) that follow the longitudinal direction of the door rail member (32) can be formed.

Thus, the concave portion (202) formed along the circumferential direction of the roller (2) and the concave portion and convex portion (344) formed along the longitudinal direction of the roller support portion (342) are configured to interlock with each other, thereby increasing the bonding force or frictional force between the door rail member (32) and the roller (2).

Thus, the effect of preventing the door rail member (32) from moving in the axial direction of the roller (2) can be increased.

Meanwhile, Fig. 12 is a cross-sectional view of a lower rail member (20) installed on the floor of a platform.

The above lower rail member (20) is formed of a metal material having a constant cross-sectional shape along the longitudinal direction so that the door member (30) can slide.

The above lower rail member (20) can be configured to have two support parts, including a main support part (22) and a sub-support part (24).

In addition, a main concave portion (382) and a sub concave portion (384) for accommodating the main support portion (22) and the sub support portion (24) can be formed at the lower portion of the door member (30).

Thus, the main concave portion (382) and the sub concave portion (384) are configured to slide while being supported by the main support portion (22) and the sub support portion (24), respectively, that is, while being supported by two support portions, thereby enabling more stable sliding movement compared to a case where sliding movement is performed while being supported by one support portion.

In addition, the door member (30) can slide reliably even during long-term operation.

Meanwhile, as shown in FIGS. 5, 6 and 13, a door opening switch (80) is installed on the back surface of the door member (30).

The above door opening switch (80) can be installed on each side of the door member (30).

The above door opening switch (80) is formed in a cylindrical shape with a circular cross-section, and has an inclined surface formed at the upper end.

Thus, the upper portion of the door opening switch (80) is formed in a trapezoidal shape in the cross-section.

And, a switch interference member (90) is installed near the door opening switch (80) at the bottom of the upper rail member (10).

The above switch interference member (90) is coupled to the lower part of the upper rail member (10) on the back surface of the upper rail member (10) (opposite side of the billboard 100).

At this time, the switch interference member (90) is coupled so as to be placed in a free state at the lower back surface of the upper rail member (10).

Thus, when the door opening switch (80) interferes with the switch interference member (90), the switch interference member (90) is configured to be able to interfere with the door opening switch (80) very flexibly.

By this configuration, even if the door opening switch (80) and the switch interference member (90) are repeatedly interfered with for a long period of time, the door opening switch (80) can be prevented from being damaged and long-term operational reliability can be maintained.

As shown in Fig. 6, the switch interference member (90) is placed on the outside of the door opening switch (80).

That is, for the door opening switch (80) installed on the left side of the back surface of the door member (30) as shown in Fig. 6, the switch interference member (90) is installed on the left side.

And, for the door opening switch (80) installed on the right side of the back surface of the door member (30), the switch interference member (90) is installed on the right side.

The above switch interference member (90) is formed convexly in a trapezoidal shape without a bottom surface toward the door opening switch (80), so that the door opening switch (80) is pressed while contacting the surface of the switch interference member (90).

Thus, when the door member (30) slides horizontally, the door opening switch (80) is pressed by interference from the switch interference member (90).

With this configuration, when the door opening switch (80) is pressed, a door opening signal is generated indicating that the door member (30) has moved.

The door opening signal generated as described above can be transmitted to the platform management office or a pre-designated external organization via wired or wireless means.

As the above wireless method, a wireless communication method or an Internet of Things method can be applied.

Thus, by transmitting the door opening signal to the platform management office or an external agency, an emergency situation is notified so that prompt action can be taken.
