Description

The present invention relates to a vehicle traffic barrier installed at a toll gate such as an expressway and capable of blocking or permitting vehicle traffic.

  In recent years, ETC (Electronic Toll Collection System) has been introduced as a system for automating toll collection in toll roads such as expressways and parking lots. In this ETC, when the vehicle detector detects the entry of the vehicle to the toll gate, the lane server issues a communication command to the roadside antenna, and based on this, the roadside antenna communicates with the vehicle-mounted device mounted on the vehicle. To start. Next, the lane server determines whether the vehicle is a normal vehicle or an abnormal vehicle based on information obtained from the vehicle-mounted device by the roadside antenna. When it is determined that the vehicle is normal, the blocking bar of the vehicle traffic barrier is opened, and when it is determined that the vehicle is abnormal, the blocking bar is kept closed so that the vehicle is blocked or permitted. It has become.

  In this ETC, there is an accident in which when the vehicle forcibly passes the vehicle passage breaker even though the blocking rod is closed, the blocking rod and the vehicle are damaged by the collision of the vehicle with the blocking rod. Arise. Therefore, in order to cope with such a problem, a vehicle traffic breaker configured such that the blocking bar performs a release operation so as to release the impact received by the blocking bar at the time of a vehicle collision has been proposed (for example, (See Patent Documents 1 and 2).

  While the vehicle traffic breaker described in these Patent Documents 1 and 2 is normally used without the vehicle colliding with the blocking bar, the blocking bar rotates in the vertical plane and is in a state of lying down horizontally. While blocking the passage of the vehicle, an opening / closing operation is performed to permit the vehicle to enter while standing vertically. When the vehicle collides with the blocking rod, the blocking rod bends along the horizontal plane in the vehicle traveling direction according to the impact, and is in a released state. In this way, the release operation of the vehicle traffic barrier is performed.

Japanese Patent No. 3594957 JP 2003-336232 A

  However, in the vehicle traffic breakers disclosed in Patent Documents 1 and 2, there is no mechanism for automatically returning the bent blocking bar after the release operation to the state before the release operation. It was necessary to approach to the point and manually return the blocking bar to the non-released state.

  Therefore, there is a case where it takes a long time to recover the blocking rod after the release operation, and there is a problem that a traffic jam of the vehicle occurs on the vehicle passage during that time. In this regard, it is conceivable to separately provide a drive unit such as an electric motor for returning the blocking rod after the release operation to the non-release state, but the configuration of the vehicle traffic breaker becomes complicated, and costs, maintenance, etc. It is not preferable from the viewpoint.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle traffic breaker capable of quickly recovering a blocking rod after a release operation with a simple configuration.

  In order to achieve the above object, the present invention employs the following means. That is, the vehicle traffic breaker according to the present invention includes an opening / closing shaft that extends in a substantially horizontal direction and is rotationally driven, a closed position that is fixed to the opening / closing shaft, and that has fallen in accordance with the rotation of the opening / closing shaft, A support arm rotatably provided to the opened position, a release shaft rotatably supported by the support arm, fixed to the release shaft, and substantially parallel to the longitudinal direction of the support arm A blocking rod that is pivotably provided to a normal position extending to a longitudinal direction of the support arm and a release position extending at a predetermined angle with respect to the longitudinal direction of the support arm, and a rotation of the support arm from the closed position to the open position. Interlocking means for rotating the blocking bar from the release position to the normal position in conjunction with movement.

  According to such a configuration, in a state where the blocking bar is in the release position due to the collision of the vehicle, for example, when the toll booth rotates the support arm from the closed position to the open position, the interlocking unit moves the blocking bar accordingly. By rotating, the blocking bar returns from the release position to the normal position.

  Further, in the vehicle traffic barrier according to the present invention, the interlocking means guides the blocking bar from the release position to the normal position when the support arm rotates from the closed position to the open position. It is a guide part.

  According to such a configuration, when the support arm is rotated, the blocking bar is guided by the guide portion, so that the blocking bar is rotated from the release position to the normal position so as to be interlocked with the support arm.

  Moreover, in the vehicle traffic breaker according to the present invention, it is preferable that the opening / closing shaft is provided so as to protrude from a surface facing the rear side in the vehicle traveling direction in the breaker body supporting the opening / closing shaft.

  According to such a configuration, since the guide portion for guiding the blocking rod can be provided in the vehicle passage breaker, the structure for installing the guide portion on the front side in the vehicle traveling direction from the vehicle passage breaker There is no need to install an object separately from the vehicle traffic barrier. Thereby, the cost reduction by material cost reduction and the space saving as the whole apparatus can be achieved.

  The vehicle traffic breaker according to the present invention is characterized in that the guide portion is provided in a breaker body.

  According to such a configuration, by providing the guide portion on the side of the breaker main body in a stationary state, the blocking bar can be more reliably moved from the release position to the normal position as compared with the case where the blocking bar is provided on the rotating blocking bar side. Can be guided to.

  Further, the vehicle traffic breaker according to the present invention is characterized in that the guide portion contacts at least one end with which the blocking bar in the release position abuts at least when the support arm rotates from the closed position to the open position. And a contact portion having the other end with which the blocking rod in the normal position abuts in a state where the arm has reached the open position.

  According to such a configuration, in the state where the support arm has reached the open position, the guide portion comes into contact with the blocking bar at the normal position, so that the blocking bar can be more reliably guided to the normal position. Note that one end of the abutting portion may abut on the blocking bar at the release position at least during the rotation of the support arm from the closed position to the open position. Therefore, the structure may be such that the blocking bar at the release position contacts the one end of the contact portion when the support arm is at the closed position.

  In the vehicle traffic breaker according to the present invention, the guide portion is at least one end with which the blocking rod in the release position contacts when the support arm rotates from the closed position to the open position. The support arm that rotates from the position to the open position has a contact portion that has the other end with which the blocking rod in the normal position contacts in a state in which the support arm further rotates beyond the open position. May be.

  According to such a configuration, the guide portion guides the blocking bar until the support arm reaches a position beyond the open position. Therefore, when the support arm rotates from the closed position to the open position after the blocking bar returns to the normal position, the support arm does not contact the guide portion. Thereby, generation | occurrence | production of the noise accompanying contact with a support arm and a guide part can be prevented, and it can prevent that a support arm and a guide part are damaged. Note that one end of the abutting portion may abut on the blocking bar at the release position at least during the rotation of the support arm from the closed position to the open position. Therefore, the structure may be such that the blocking bar at the release position contacts the one end of the contact portion when the support arm is at the closed position.

  Further, in the vehicle traffic breaker according to the present invention, the distance between the axis of the opening and closing shaft and the contact portion gradually increases as the support arm moves from the closed position to the open position. It is characterized by.

Accordingly, the blocking bar can be more reliably rotated from the release position to the normal position with the rotation of the support arm.
Furthermore, in the vehicle traffic breaker according to the present invention, the interlocking means includes a locking means for locking the blocking bar so as not to move at the release position, and the blocking bar is rotated from the release position toward the normal position. A configuration may be provided that includes a return spring that is biased in the direction in which the lock is released, and a lock release unit that releases the lock by the lock unit while the blocking bar is rotating from the release position to the normal position.
According to such a configuration, the blocking rod can be returned and rotated to the normal position by the biasing force of the return spring in conjunction with the rotation of the support arm from the closed position to the open position.

  According to the vehicle traffic barrier according to the present invention, when the support arm is rotated from the closed position to the open position, the blocking bar can be returned from the release position to the normal position in conjunction with the operation. Therefore, it is not necessary to separately provide a drive unit for returning the blocking bar from the release position to the normal position, and the blocking bar after the release operation can be quickly recovered with a simple configuration.

  Embodiments of the present invention will be described below with reference to the drawings. First, the configuration of a vehicle traffic breaker (hereinafter abbreviated as “breaker”) according to an embodiment of the present invention will be described. 1 to 4 are views showing the appearance of the circuit breaker 10 according to the present embodiment. FIG. 1 is a schematic perspective view as seen from the front side, FIGS. 2 and 3 are schematic front views, and FIG. It is a top view. As shown in FIG. 1, the breaker 10 includes a breaker body 11, a support arm 12 attached to the front side of the breaker body 11, and a long blocking bar 13 supported by the support arm 12. The guide part (interlocking means) 14 provided in the upper part of the circuit breaker main body 11 is provided. In addition, the front of the circuit breaker main body 11 means the side surface when the circuit breaker 10 is seen toward the vehicle traveling direction.

  As shown in FIGS. 1 to 4, the breaker main body 11 includes a casing 111 as a housing, an opening / closing shaft 112 that is provided to protrude from the front side of the casing 111 in a horizontal direction, and is rotatable. And an open / close shaft drive motor 113 (shown in FIG. 7) that is housed therein and rotationally drives the open / close shaft 112. Here, as shown in FIG. 1, an inclined surface 111 a that is gradually inclined upward as the distance from the vehicle traffic path R increases is provided on the upper side surface of the casing 111. The open / close shaft drive motor 113 is a so-called servo motor that can arbitrarily control the rotation speed and rotation angle thereof, and its rotation is transmitted to the open / close shaft 112 via a gear transmission mechanism and a belt transmission mechanism (not shown). The

  As shown in FIGS. 2 and 3, the breaker body 11 configured in this way is fixedly installed on the side of the vehicle traffic route R in the toll gate on the highway. The position where the breaker main body 11 is installed is not limited to the toll gate on the highway, and may be a toll gate in a parking lot, for example.

  As shown in FIGS. 1 and 4, the support arm 12 includes a main body 121, a release shaft 122 rotatably supported on one end of the main body 121, and a blocking bar 13 fixed to the release shaft 122. And a holder portion 123 for holding. Thereby, the holder part 123 can be rotated with respect to the main body part 121 with the rotation of the release shaft 122. The main body 121 of the support arm 12 thus configured is fixed to the opening / closing shaft 112. Thereby, the support arm 12 rotates in the vertical plane with the rotation of the opening and closing shaft 112, and the rotation range is from the open position K shown in FIG. 1 to the closed position shown in FIG. It is up to H. In addition, the open position K of the support arm 12 in this embodiment means the state which the support arm 12 stood substantially vertically as shown in FIG. 1, and the closing position H of the support arm 12 is shown in FIG. As shown, this means that the support arm 12 has fallen substantially horizontally.

  Here, FIG. 5 and FIG. 6 are views showing the internal configuration of the support arm 12, FIG. 5 is a schematic longitudinal sectional view, and FIG. 6 is a schematic transverse sectional view. A release mechanism 15 is provided inside the support arm 12. The release mechanism 15 keeps the blocking bar 13 in a non-released state during normal times, i.e., when the vehicle does not collide with the blocking bar 13, while the vehicle does not touch the blocking bar 13 in an abnormal state. In the case of a collision, this is a mechanism for causing the blocking bar 13 to perform a release operation. As shown in FIGS. 5 and 6, the release mechanism 15 includes a release spring 16, a torque limiter 17, and a latch mechanism 18.

  The release spring 16 is a coil spring that urges the blocking bar 13 in the release direction T1 shown in FIG. 6, and one end of the release spring 16 is fixed to a first spring fixing portion 121a provided in the main body 121. The other end is fixed to a second spring fixing portion 123 a provided in the holder portion 123. The release spring 16 is in an extended state when the blocking bar 13 is in the normal position N shown in FIG. 6, that is, a position extending in parallel with the longitudinal direction of the support arm 12. A rotational moment in the release direction T1 with 122 as a fulcrum is applied.

  The torque limiter 17 prevents the torque exceeding a predetermined magnitude from acting on the blocking bar 13 and the support arm 12. The torque limiter 17 includes a locked portion 171 provided in the holder portion 123, and a locking portion 172 and a holding spring 173 provided in the main body portion 121.

  The locked portion 171 cooperates with the locking portion 172 to hold the blocking bar 13 at the normal position N shown in FIG. 6 against the rotational moment in the release direction T1 applied from the release spring 16. To do. As shown in FIG. 6, the locked portion 171 is provided so as to protrude from the inner surface of the holder portion 123 constituting the support arm 12, and a locking protrusion 171 a is provided at the distal end portion thereof.

  The locking portion 172 holds the blocking bar 13 at the normal position N shown in FIG. 6 against the rotational moment in the release direction T1 applied from the release spring 16 in cooperation with the locked portion 171. To do. As shown in FIG. 6, the engaging portion 172 is formed with a hooking groove 172a having a shape that fits with the engaging protrusion 171a of the locked portion 171. The opening edge of the hooking groove 172a is convex. A shaped peak portion 172b is formed. The locking portion 172 configured in this manner is rotatably supported by a support shaft 124 that protrudes from the inner surface of the main body 121.

  The holding spring 173 gives a rotational moment about the support shaft 124 to the locking portion 172. The holding spring 173 is a so-called coil spring. As shown in FIGS. 5 and 6, one end of the holding spring 173 is disposed on the inner surface of the main body 121 via the first spring support 125 and the other end is a second spring. By being connected to the locking portion 172 via the support portion 172c, the stretched state is obtained. Accordingly, the holding spring 173 applies a counterclockwise rotational moment to the locking portion 172 with the support shaft 124 as a fulcrum.

  According to the torque limiter 17 configured as described above, when the blocking bar 13 is located at the normal position N shown in FIG. 6, the locked portion 171 of the holder portion 123 is inserted into the main body portion 121, and The locking protrusion 171 a of the locking part 171 is fitted in the hooking groove 172 a of the locking part 172. At this time, the counterclockwise rotational moment that the holding spring 173 applies to the locking portion 172 and the clockwise rotational moment that the release spring 16 applies to the locking portion 172 via the locked portion 171 are generated. The balanced portion 171 is stopped at the position shown in FIG. Accordingly, the locking protrusion 171a of the locked portion 171 cannot be pulled out of the hooking groove 172a because the peak portion 172b becomes an obstacle. Accordingly, the blocking bar 13 is held at the normal position N shown in FIG. 6 regardless of the rotational moment received from the release spring 16 in the release direction T1.

  The latch mechanism 18 holds the blocking bar 13 at a release position described later. As shown in FIG. 6, the latch device includes a latch device 181 provided on the inner surface of the holder portion 123 and a latch hooking portion 182 provided so as to protrude from the outer surface of the main body portion 121. .

  As shown in FIG. 6, the latch device 181 includes a latch 181 a that can project and retract toward the release shaft 122, and an elastic body such as a spring that urges the latch 181 a in the protruding direction. And an operation knob 181b for manually immersing the latch 181a. Although details are not shown in FIG. 6, a solenoid is housed in the latch device 181, and a current is passed through the solenoid in response to a command from a control unit described later, so that the latch 181 a is applied to the urging force of the elastic body. I have become immersive against it. According to the latch device 181 configured as described above, when the blocking bar 13 is located at the normal position N shown in FIG. 6, the latch 181 a that receives the biasing force of the elastic body projects from the latch device 181. It has become.

  The guide portion 14 is for interlocking the opening operation of the support arm 12 and the release return operation of the blocking bar 13. As shown in FIG. 1, the guide portion 14 is a flat plate-like member formed in a substantially triangular shape, and is arranged so as to obliquely cross the inclined surface 111 a of the circuit breaker body 11, and one side portion thereof is an inclined surface. It is fixed to 111a. Thus, the guide surface (contact portion) 141 formed on the top of the guide portion 14 is the lowermost portion of the inclined surface 111a and the uppermost portion of the inclined surface 111a from one end located on the back side of the casing 111. The other end of the casing 111 is obliquely extended toward the other end of the casing 111 so as to be gradually inclined upward. As a result, the guide surface 141 moves from the contact position with the blocking bar 13 as the blocking bar 13 rotates from the release position R shown in FIG. 9 to the normal position N shown in FIG. This distance extends to the opening / closing shaft 112, that is, the distance between the axis of the opening / closing shaft 112 and the guide surface 141 when viewed from the rear side in the vehicle traveling direction.

  In addition, as shown in FIG. 1, the guide surface 141 gradually increases in height from the inclined surface 111a as it goes from the lower part to the upper part of the inclined surface 111a. Further, as shown in FIGS. 9 and 10, one end of the guide surface 141 is located below the blocking bar 13. Further, the other end of the guide surface 141 slightly protrudes from the front side of the casing 111 to the front side. More specifically, the other end of the guide surface 141 extends to a position where it comes into contact with the support arm 12 in the open position K, as shown in FIG. As a result, the guide surface 141, as shown in FIG. 1, from the position where it comes into contact with the blocking bar 13 when the support arm 12 is in the closed position H and the blocking bar 13 is in the release position R as shown in FIG. Further, the support arm 12 extends to a position where it comes into contact with the blocking bar 13 in the open position K and the blocking bar 13 in the normal position N.

  The material, shape, size, and the like of the guide portion 14 are not limited to the present embodiment, and can be appropriately changed in design. For example, in this embodiment, the guide portion 14 is installed so that the guide surface 141 obliquely crosses the inclined surface 111a. Instead, the rising angle of the guide surface 141 matches the inclination angle of the inclined surface 111a. The guide part 14 may be installed in the door. In this case, the position where the guide portion 14 contacts in the longitudinal direction of the blocking bar 13 is always constant even if the support arm 12 rotates. However, if the guide portion 14 is installed as in the present embodiment, the position where the guide surface 141 of the guide portion 14 contacts in the longitudinal direction of the blocking rod 13 is the position of the blocking rod 13 as the support arm 12 rotates. It gradually moves from the distal end side toward the proximal end side. Therefore, compared with the case where the guide surface 141 of the guide portion 14 is always in contact with the same position of the blocking bar 13, the guide portion 14 is formed to be smaller because the distance from the guide surface 141 to the inclined surface 111a is small. Can do. As a result, cost reduction and parts management can be facilitated.

  In this embodiment, as shown in FIGS. 2 and 3, the guide portion 14 is formed so that the guide surface 141 extends linearly in a plan view. Instead, the guide surface 141 is curved in a plan view. You may form the guide part 14 so that it may become a shape. In the present embodiment, the guide portion 14 is formed so that the guide surface 141 is a flat surface, but instead, the guide portion 14 may be formed so that the guide surface 141 is a curved surface.

  Further, in the present embodiment, the guide portion 14 is configured as a substantially triangular flat plate member. However, the guide portion 14 only needs to have a guide surface 141 that contacts and guides the blocking bar 13. For example, the guide surface 141 includes the guide surface 141. The guide portion 14 may be configured by the formed rail and a support leg that supports the rail at a predetermined height position from the inclined surface 111a. Moreover, although the guide part 14 was installed in the circuit breaker main body 11 in this embodiment, it may replace with this and may install the guide part 14 on the ground.

  Next, the functional configuration of the circuit breaker 10 will be described. FIG. 7 is a functional block diagram showing functional configurations of the circuit breaker 10 and peripheral devices. In the circuit breaker 10, the opening / closing axis drive motor 113 and the solenoid 19 accommodated in the latch device 181 are electrically connected to the control unit 20. Further, an operation unit 21 provided outside the circuit breaker 10 is electrically connected to the control unit 20. The control unit 20 is configured to control the opening / closing axis drive motor 113 based on an input from the operation unit 21.

  In addition, a lane server 24 to which a vehicle detection unit 22, a roadside antenna 23, and the operation unit 21 are connected as peripheral devices is provided outside the circuit breaker 10. The lane server 24 is electrically connected to the opening / closing axis drive motor 113 of the circuit breaker 10.

  The vehicle detection part 22 is comprised by the several pairs of optical sensor installed in the both sides of the vehicle traffic path R, for example, and is comprised so that the entrance and exit of the vehicle to a toll gate may be detected. That is, this vehicle detection part 22 detects the approach of the vehicle to the toll gate by using a first optical sensor installed on the entrance side of the toll gate (the rear side in the vehicle traveling direction G of the circuit breaker 10), for example. On the other hand, the exit of the vehicle from the toll gate is detected by a second optical sensor installed on the exit side of the toll gate (front side in the vehicle traveling direction G of the circuit breaker 10).

The roadside antenna 23 is installed, for example, behind the circuit breaker 10 in the vehicle traveling direction G so that when the vehicle passes through the toll gate, it transmits and receives necessary information with the vehicle-mounted device mounted on the vehicle. It is configured.
The lane server 24 is configured to control the opening / closing axis drive motor 113 of the circuit breaker 10 based on outputs from the vehicle detection unit 22 and the roadside antenna 23.

  The operation unit 21 is installed in a room of a tollgate in the vicinity of the toll booth. For example, when the “open button” or the “close button” is pressed, Outputs an open / close request. The lane server 24 opens and closes the blocking bar 13 by issuing a command to the opening / closing axis drive motor 113 based on the opening / closing request. The operation unit 21 may be installed in a monitoring center or the like located away from the toll gate.

Further, as described above, the operation unit 21 is also connected to the control unit 16 of the circuit breaker 10. For example, a release return command sent by operating a “release return button” is sent to the control unit 16. It is configured to be entered.
The operation unit 21 is also provided with a button for operating energization or deenergization of the solenoid 19. Based on a command issued from the operation unit 21, the control unit 20 energizes the solenoid 19 to immerse the latch 181 a into the latch device 181.
The operation unit 21 may be configured not to be connected to the lane server 24 but only to the control unit 16. In this case, the opening / closing request output by operating the operation unit 21 is input to the control unit 16, and the control unit 16 controls the opening / closing shaft drive motor 113 based on the opening / closing request to open / close the blocking rod 13. Perform the action.

Next, the effect | action of the circuit breaker 10 of this embodiment is demonstrated.
When the vehicle has not entered the vehicle traffic path R and the circuit breaker 10 is in the standby state, the support arm 12 is in the closed position H, which is the home position, as shown in FIG.

  First, the processing procedure of the opening / closing operation of the blocking bar 13 when the vehicle enters the toll gate having the circuit breaker 10 in the standby state as described above will be described. The opening / closing operation of the blocking bar 13 is performed under the control of the lane server 19. FIG. 8 is a flowchart showing a processing flow of the opening / closing operation of the blocking bar 13 executed by the lane server 24.

  First, the lane server 24 determines whether or not the vehicle detection unit 22 has detected the entry of a vehicle to the toll gate, that is, whether or not an ON signal (vehicle detection signal) from the vehicle detection unit 22 has been input. (S11). As a result, when it is determined that an OFF signal is input from the vehicle detection unit 22 (S11: No), the lane server 24 stands by until an ON signal is input from the vehicle detection unit 22. On the other hand, when it is determined that the ON signal is input from the vehicle detection unit 22 (S11: Yes), the lane server 24 sends a reception command for the vehicle-mounted device information to the roadside antenna 23 (S12). Starts communication with the vehicle-mounted device mounted on the vehicle based on this signal.

Next, the lane server 24 determines whether the vehicle about to pass through the toll gate is a normal vehicle or an abnormal vehicle based on the vehicle-mounted device information received by the roadside antenna 23 (S13). As a result, when it is determined that the vehicle is an abnormal vehicle (S13: No), the lane server 24 performs an abnormal process (S14) and maintains the support arm 12 at the closed position H. Thereby, the process of the lane server 24 is complete | finished.
On the other hand, if it is determined that the vehicle is a normal vehicle in S13, the lane server 24 sends a vehicle passage permission command to the open / close shaft drive motor 113 and rotates the open / close shaft 112 of the open / close shaft drive motor 113 in the forward direction. The support arm 12 is rotated from the closed position H to the open position K (S15). In this way, the blocking bar 13 of the circuit breaker 10 is in a state in which the passage of the vehicle is permitted according to the vehicle passage permission command.

  After S15, the lane server 24 determines whether or not the vehicle has detected exit from the toll gate, that is, whether or not an OFF signal has been input from the vehicle detection unit 22 as a result of completion of vehicle detection by the vehicle detection unit 22. Is determined (S16). If it is determined that the ON signal is still input from the vehicle detection unit 22 (S16: No), the lane server 24 stands by until an OFF signal is input from the vehicle detection unit 22. On the other hand, when it is determined that the OFF signal is input from the vehicle detection unit 22 (S17: Yes), the lane server 24 sends a signal to the opening / closing shaft drive motor 113 and rotates the opening / closing shaft 112 in the reverse direction, thereby supporting the support arm 12. Is rotated from the open position K to the close position H (S17). Thereby, it will be in the state which the circuit breaker 10 blocked | prevented the passage of a vehicle. Thereby, the process of the lane server 24 is complete | finished.

  Next, the release operation of the blocking bar 13 in an emergency, that is, when the vehicle collides with the blocking bar 13 will be described. As described above, in the normal state, the blocking bar 13 is in a normal position N shown in FIG. 2, that is, a position extending in parallel with the longitudinal direction of the support arm 12. The support arm 12 repeats the opening / closing operation by rotating between the closing position H shown in FIG. 2 and the opening position K shown in FIG. Here, although the support arm 12 is in the closed position H shown in FIG. 2 and the blocking bar 13 is in a state where the vehicle is prevented from passing, the vehicle does not stop due to the driver's intention or carelessness. In some cases, the vehicle may come into contact with the bar portion 132 of the blocking bar 13.

  In this case, when the rotational moment acting on the blocking rod 13 due to the impact received from the vehicle exceeds a predetermined magnitude, the locking portion 172 and the locked portion 171 constituting the torque limiter 17 shown in FIG. Canceled. More specifically, when the rotational moment around the release shaft 122 acting on the blocking bar 13 exceeds a predetermined magnitude, the rotational moment that the locked portion 171 tries to rotate the locking portion 172 clockwise. However, the holding spring 173 is larger than the rotational moment that tries to rotate the locking portion 172 counterclockwise. As a result, although not shown in detail in the drawing, the locking portion 172 rotates clockwise around the support shaft 124 as a fulcrum. Then, the crest 172b formed at the opening edge of the hooking groove 172a deviates from the rotation trajectory of the locking projection 171a, so that the locking projection 171a goes out of the hooking groove 172a beyond the peak 172b, The locking between the locking portion 172 and the locked portion 171 is released.

  Here, FIG. 9 to FIG. 11 are diagrams for explaining the release operation of the blocking bar 13, FIG. 9 is a schematic perspective view of the breaker 10 viewed from the front side, and FIG. 10 is a schematic view of the breaker 10. FIG. 11 is a schematic cross-sectional view showing the internal structure of the support arm 12 and the blocking bar 13. As described above, when the locking of the locking portion 172 and the locked portion 171 is released, the blocking bar 13 supports the release shaft 122 from the normal position N shown in FIG. 6 by the urging force of the release spring 16. The rotation in the release direction T1 is started. The blocking bar 13 rotates until reaching the release position R shown in FIGS. 9 and 10, that is, a position extending perpendicularly to the longitudinal direction of the support arm 12.

  Then, as shown in FIG. 11, the blocking bar 13 is held non-rotatable at the release position R by the latch mechanism 18. More specifically, the front end of the latch 181a contacts the latch hook 182 immediately before reaching the release position R of the blocking bar 13 that rotates in the release direction T1. Then, although not shown in detail in the drawing, the latch 181a pressed by the latch hooking portion 182 enters the inside of the latch device 181 against the urging force received from the elastic body. In this state, the blocking rod 13 further rotates in the release direction T1, so that the latch 181a gets over the latch hooking portion 182. Thereafter, as shown in FIG. 11, when the blocking bar 13 reaches the release position R, the latch 181a protrudes from the latch device 181 again by the urging force of the elastic body due to the tip of the latch 181a moving away from the latch hooking portion 182. It becomes a state. Here, when the blocking bar 13 tries to rotate from the release position R shown in FIG. 11 in the return direction T2, the tip of the latch 181a comes into contact with the latch hook 182. However, the pressing force received by the latch 181a from the latch hooking portion 182 at this time does not have a component component in the direction in which the latch 181a is immersed in the latch device 181. As a result, the latch 181a remains protruding from the latch device 181 even when it comes into contact with the latch hook 182. Therefore, the latch 181a cannot get over the latch hook 182. In this way, the blocking bar 13 is restricted from rotating from the release position R in the return direction T2 and is locked at the release position R.

  Next, a release return operation for returning the blocking bar 13 from the release position R to the normal position N after completion of the release operation will be described. This release return operation is performed based on a return command sent out by operating the operation unit 21 by, for example, a tollgate. 12 and 13 are diagrams for explaining the release return operation. FIG. 12 is a flowchart showing the flow of the release return operation. FIG. 13 is a schematic view of the circuit breaker 10 as seen from the front side. It is a perspective view.

  As shown in FIG. 12, when the release return operation is started, the control unit 20 first determines whether or not a return command is input from the operation unit 21 (S6). As a result, when it is determined that the return command is not input from the operation unit 21 (S6: No), the control unit 20 waits until the return command is input from the operation unit 21.

  On the other hand, when it is determined in S6 that the return command is input from the operation unit 21 (S6: Yes), the control unit 20 sends a command to energize the solenoid 19 accommodated in the latch device 181 (S7). As a result, the latch 181a enters the inside of the latch device 181 against the urging force of the elastic body, and the blocking bar 13 is released from the locked state at the release position R shown in FIG. The rotation is allowed. In this state, the control unit 20 reversely rotates the opening / closing axis drive motor 113 to rotate the support arm 12 by approximately 90 ° from the closed position H shown in FIG. 9 to the open position K shown in FIG. (S8). And the control part 20 complete | finishes a process as it is.

  Here, when the rotation of the support arm 12 starts, as shown in FIG. 9, the blocking bar 13 at the release position R starts to rotate about the opening / closing shaft 112 shown in FIG. Then, the surface of the blocking bar 13 on the side of the breaker body 11 comes into contact with the lowermost portion of the guide surface 141 of the guide portion 14, that is, one end of the guide surface 141. When the support arm 12 further rotates from this state, the blocking bar 13 moves along the guide surface 141 accordingly. Here, the height of the guide surface 141 from the inclined surface 111a gradually increases as it goes from the lower part to the upper part of the inclined surface 111a. Accordingly, as shown in FIG. 13, the blocking bar 13 is gradually pushed upward while moving along the guide surface 141, that is, the blocking bar 13 rotates around the release shaft 122 in addition to turning around the opening / closing shaft 112. The movement also starts. As a result, the blocking bar 13 gradually stands up as shown in FIG. 13 from the state where it horizontally falls as shown in FIG. As shown in FIG. 1, when the support arm 12 reaches the open position K, the blocking bar 13 returns to the normal position N. In this state, the blocking bar 13 is in contact with the other end of the guide surface 141.

  As described above, according to the release return operation according to the present invention, the toll gate person approaches the breaker 10 manually to return the blocking bar 13 after the release operation is completed to the state before the release operation. It is not necessary to rotate the blocking bar 13 around the release shaft 122, and if the support arm 12 is rotated from the closed position H to the opened position K by remote control, the blocking bar 13 is linked to the release position K. Return from R to the normal position N. As a result, the time required to return the blocking bar 13 after the release operation to the state before the release operation can be shortened, and it is possible to prevent the occurrence of a vehicle traffic jam during the recovery work after the release operation. be able to.

The various shapes, combinations, operation procedures, and the like of the constituent members shown in the above-described embodiments are merely examples, and various changes can be made based on design requirements and the like without departing from the gist of the present invention.
For example, in the embodiment, a description has been given of an example in which the toll booth clerk remotely rotates the support arm 12 to the open position K to return the blocking bar 13 to the normal position state. Is set to the release position R, the following vehicle is detected by the vehicle detection unit, and the blocking arm 13 is also returned to the normal position N by the support arm 12 rotating to the open position K based on this. You may let them.

  In the embodiment, the latch bar 18 is configured to hold the blocking bar 13 at the release position R so as not to rotate. Instead, for example, the male bar provided on the blocking bar 13 and the casing 111 are provided. A configuration may be adopted in which a ball catch composed of a female member is provided, and the blocking bar 13 is fixed at the release position R by engaging the male member with the female member.

  14 and 15 are diagrams showing a modification of the present embodiment. In this modification, when the blocking bar 13 guided by the guide portion 14 reaches the normal position N from the release position R, the overswing position O in which the support arm 12 is further rotated beyond the vertical state that is the open position K. It is characterized by reaching. That is, as shown in FIG. 15, the other end of the guide surface 141 of the guide portion 14 protrudes to the front side of the front of the breaker body 11, and is in a position rotated beyond the open position K as shown in FIG. It extends to a position where it abuts against a certain support arm 12. According to such a configuration, the guide portion 14 guides the blocking bar 13 until the supporting arm 12 reaches the overswing position O beyond the open position K. Therefore, after the blocking bar 13 returns to the normal position N, the supporting arm When the arm 12 rotates from the closed position H to the open position K, the support arm 12 does not contact the guide portion 14. Thereby, generation | occurrence | production of the noise accompanying the contact with the support arm 12 and the guide part 14 can be prevented, and it can prevent that the support arm 12 and the guide part 14 are damaged.

  FIG. 16 is a diagram illustrating another modification of the present embodiment. In the present modification, the blocking bar 13 is provided so as to be rotatable with respect to the support arm 12 via a rotation support shaft 25. The support arm 12 and the blocking bar 13 are connected to each other by a return spring 26. According to such a configuration, when the blocking bar 13 starts to rotate by being guided by the guide portion 14, the blocking bar 13 is subjected to the biasing force of the return spring 26 as shown in FIG. Rotate against it. Thereafter, as shown in FIG. 16B, when the blocking bar 13 further rotates beyond the state where both ends of the return spring 26 and the rotation support shaft 25 are positioned in a straight line, the urging force of the return spring 25 The blocking bar 13 that has received this automatically returns to the normal position N as shown in FIG. According to such a configuration, since the second half of the rotation of the blocking bar 13 from the release position R to the normal position N is performed by the biasing force of the return spring 25, the blocking bar 13 reaches the release position R. There is no need to extend the guide part 14 to the end.

  In the present embodiment, the interlocking means according to the present invention is configured by the guide member 14, but the interlocking means may have other configurations. For example, although not shown in detail in the figure, the interlocking means includes a locking means for locking the blocking bar 13 at the release position R so that it cannot move, and a direction in which the blocking bar 13 is rotated from the release position R toward the normal position N. You may comprise from the return spring to urge, and the lock release means which cancels | releases the lock | rock by a lock means in the middle of the prevention rod 13 rotating from the release position R to the normal position N. According to such a configuration, when the lock is released by the lock release means, the blocking bar 13 automatically returns from the release position R to the normal position N by the biasing force of the return spring. Therefore, in conjunction with the rotation of the support arm 12 from the closed position H to the open position K, it is possible to function as interlocking means for rotating the blocking bar 13 from the release position R to the normal position N. According to such a configuration, for example, even if the guide portion 14 is not provided on the breaker body 11, the contact portion where the blocking bar 13 and the breaker body 11 come into contact with the blocking bar 13 side of the breaker 10 or the breaker body. By providing either or both of the 11 side, the blocking bar 13 and the breaker body 11 come into contact with each other via the contact portion in conjunction with the rotation of the support arm 12 from the closed position H to the open position K. As shown in FIG. 16, after a certain angle release shaft returns and rotates, it can be returned and rotated to the normal position N by the biasing force of the return spring.
