Abstract

PROBLEM TO BE SOLVED: To provide a gate device with a smaller space for a gate bar to move when resuming to an original position, for preventing damage to the gate device when a vehicle collided into the gate bar that moves in a horizontal direction on a vehicle passage for resuming to the original position.SOLUTION: With a gate device 1, a release operation is performed when a vehicle collides into a gate bar 24 that blocks a vehicle passageway 2, separating an end of the gate bar 24 from an end of a gate bar base part 21 and rotating in a moving direction of the vehicle. After the gate bar 24 performs the release operation, a rotating part 15 on a body part 11 rotates around a vertical rotation axis 17 in such a way to follow the rotation of the gate bar 24. When the rotating part 15 starts rotating, the end of the gate bar base part 21 comes close to the end of the gate bar 24. When the rotating part 15 rotates further, the end of the gate bar base part 21 is engaged with the end of the gate bar 24, unifying and fixing the two. Then, the rotating part 15 rotates in the opposite direction, and the gate bar 24 returns to a position before starting the release operation.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a gate device that controls traffic regulation of vehicles or the like at a toll gate of a highway or a toll road or a toll parking lot, and more particularly to a release automatic return function of the gate bar.

  Conventionally, for example, when an ETC (Electronic Toll Collection System) gate on a toll road or an entrance / exit of a parking lot, when the vehicle collides with the gate bar, the gate bar is rotated (released) in the vehicle traveling direction to prevent the gate bar from being damaged. Thus, a gate device for returning the released gate bar automatically or remotely is realized. For example, Patent Documents 1, 2, 3 and the like disclose such a gate device.

  Patent Document 1 describes a gate device including means for enabling a worker to perform a recovery operation of a blocking bar that has been rotated in the vehicle traveling direction when a vehicle collides without leaving the vehicle lane. In this device, when a vehicle collides with a blocking bar held in the blocking bar holder in the horizontal direction, the blocking bar holder with the blocking bar inserted rotates around the holder rotation axis and is released from the connecting member to drive the blocking bar. The direction is parallel to the rotation axis. Further, when the released blocking bar is restored, the blocking bar driving rotary shaft is rotated together with the connecting member, and the blocking bar holder into which the blocking bar is inserted is positioned above the blocking bar driving device. , The arm provided on the upper surface of the blocking bar drive device is rotated upward, the blocking bar is pushed up from the bottom by this arm, the blocking bar holder into which the blocking bar is inserted is stored in the connecting member, and then the blocking bar is rotated. Rotate the shaft and position the blocking bar horizontally.

  Japanese Patent Application Laid-Open No. 2004-228688 describes a breaker returning device that can return the breaker to a vertically rotating state by a switch operation when the breaker is in the retracted position. In this apparatus, the blocking rod extends in a direction intersecting the axial direction of the drive shaft, and rotates in the vertical direction by the rotation of the drive shaft. The barrier rod is hinged to the barrier rod drive shaft so that it can be rotated in the horizontal direction from the closed position to the retracted position. This device has a reciprocating arm that is driven by an actuator and moves forward and backward in the axial direction of the drive shaft. When returning the barrier rod in the retracted position to the vertical rotation state, the reciprocating arm that moves forward is locked to the projecting piece provided at the hinge connecting end of the barrier rod, and the barrier rod is perpendicular to the retracted position. Push back to the direction rotation state.

  Patent Document 3 describes a vehicle traffic breaker that prevents inadvertent rotation of a blocking bar in a normal state and quickly and easily returns the blocking bar after a release operation. In this apparatus, in the standby state, the blocking bar is held in a normal state in which the passage of the vehicle is blocked by the engagement between the stopper means and the engagement mechanism. When the vehicle collides with the blocking bar, the engagement between the stopper means and the engagement mechanism is released, and the blocking bar changes from the normal state to the released state. After that, for example, when a staff member at the toll gate operates the operation unit, the pressing bar is rotated by the return motor of the return driving unit, and the blocking bar is pressed to return from the released state to the normal state.

  By the way, in the gate device of Patent Document 1, when the released blocking bar is restored, the blocking bar in a bent state is moved above the blocking bar driving device, and then the blocking bar is pushed up by the arm. . For this reason, a space for rotating the blocking bar approximately 90 degrees from behind the blocking bar driving device (in the vehicle traveling direction) to above the blocking bar driving device must be secured around the blocking bar driving device. In particular, as the blocking bar moves upward of the blocking bar driving device, it moves to the intermediate position in the left-right direction of the island on which the blocking bar driving device is mounted, and then rotates 90 degrees upward at that position. . For this reason, in order to enable safe rotation movement of the blocking bar, it is necessary to secure a wide space above the left and right intermediate portion of the island. As a result, there is a problem that the installation location is limited when other devices related to vehicle traffic regulation control such as a passage detection device and a height measurement device are installed in the vicinity of the gate device.

  Further, in the breaking rod returning device of Patent Document 2, when the retracted breaking rod is restored, the breaking rod is pushed back in the horizontal direction from the retracted position to the vertical rotation state by the reciprocating arm. For this reason, when the barrier rod is restored, the barrier rod moves above the roadway so as to block the roadway. Further, while the barrier rod is moving for return, a pressing force is applied to the barrier rod in a direction almost opposite to the vehicle traveling direction by the reciprocating arm. As a result, when the vehicle traveling on the roadway collides with the barrier rod during the return operation, the barrier rod cannot be retracted, and the barrier rod and other parts of the barrier rod returning device may be damaged. In order to avoid such a situation, it is conceivable that the roadway is closed in an inaccessible state until the return is completed after the barrier bar is retracted. Since the vehicle is in the retracted position, it is practically difficult to restrict a vehicle that intentionally or mistakenly enters the vehicle by simply indicating that no entry is possible.

  Also, in the vehicle traffic breaker disclosed in Patent Document 3, the blocking bar moves so as to block the roadway for returning as in the case of the breaker returning apparatus disclosed in Patent Document 2, so that the blocking bar during the return operation of the vehicle is being used. In the event of a collision, there is a risk of damaging the blocking bar and other parts of the vehicle traffic barrier. Furthermore, in the vehicle traffic breaker disclosed in Patent Document 3, the return pressure bar protrudes to the road side together with the blocking bar during the returning operation of the blocking bar, which may increase the degree of breakage of the vehicle traffic breaker due to the vehicle collision. There is.

FIG. 2 shows a part of the release operation and the return operation of the gate bar 24 in the gate apparatus 1 in FIG. FIG. 3 shows a roadway opening / closing operation by the gate device 1.

  In FIG. 1, a gate device 1 according to an embodiment of the present invention is placed on an island 3 that is a concrete platform formed along a roadway 2 along a roadway 2 at a gate such as a toll gate or an entrance / exit. is set up. The gate device 1 restricts a vehicle (moving body) traveling on the roadway 2 from passing through the gate. It is desirable that the surface of the gate device 1 on the side of the road 2 and the curb portion of the island 3 on the side of the road 2 are as close as possible, and the closer the approach, the shorter the length of the gate bar 24 is. it can. Here, for convenience of explanation, when standing at the point on the roadway 2 before passing the gate, the front side is “front”, the other side is “rear”, the right side is “right”, the left side Is defined as “left”, the upper side is defined as “upper”, and the lower side is defined as “lower”. In the following, in the embodiments, directions will be described. In this case, the vehicle traveling on the roadway 2 approaches the gate device 1 from the front of the gate device 1, and then proceeds to the rear of the gate device 1.

  The gate device 1 includes a main body portion 11 disposed on the lower side and a rotating portion 15 disposed on the upper side. The main body 11 includes a main body casing 12 formed in a rectangular column shape, and the main body casing 12 is fixed on the island 3 via a main body base 13. An opening / closing lid (not shown) is attached to the rear surface of the main body housing 12 so as to be opened and closed. When the opening / closing lid is opened, almost the entire rear surface of the main body housing 12 opens. Yes.

  The rotating part 15 is provided above the main body part 11. The rotation unit 15 includes a rotation housing 16 formed in a box shape. When the gate device 1 is viewed from above, it is desirable that the rectangular outer shape of the rotating housing 16 is the same as the rectangular outer shape of the main body housing 12. An opening / closing door (not shown) is attached to the rear surface of the rotating housing 16 so as to be openable and closable so that when the opening / closing door is opened, substantially the entire rear surface of the rotating housing 16 opens. It has become.

  Moreover, the rotation part 15 is supported by the main body part 11 through a vertical rotation shaft 17 extending in the vertical direction so as to be rotatable. Thereby, the rotation unit 15 can rotate around the vertical rotation shaft 17. That is, the rotation unit 15 can be rotated in the horizontal direction, and along with the rotation of the rotation unit 15, members provided in the rotation unit 15 such as a horizontal rotation shaft 23 and a gate bar base 21 described later. Also rotate horizontally. When the gate device 1 is viewed from above, the vertical rotation shaft 17 in this embodiment is disposed at the center of the rotation unit 15 and the main body unit 11. In addition, a rotation drive unit 18 that rotates the rotation unit 15 around the vertical rotation shaft 17 is provided in the main body housing 12 of the main body unit 11. The rotation drive unit 18 includes a rotation drive motor 74 (see FIG. 10) and the like as will be described later. As will be described later, the rotation unit 15 rotates when the gate bar 24 that has been released is returned to the state before the release operation, that is, the original state in which the road opening and closing operation is possible.

  Furthermore, the gate device 1 includes a gate bar base portion 21 and a gate bar 24 which are members that block the roadway 2 at the gate. The gate bar base portion 21 is a long member formed in a U-shaped cross section, and a wall portion 22 (see FIG. 7B) is provided at one end portion. Further, one end side of the gate bar base portion 21 is rotatably supported by the rotation portion 15 via a horizontal rotation shaft 23 extending in the horizontal direction. On the other hand, the other end side of the gate bar base 21 extends in a direction intersecting with the horizontal rotation shaft 23 (a direction orthogonal to the horizontal rotation shaft 23 in the present embodiment).

  The gate bar 24 is formed long and connected to the gate bar base 21. The gate bar 24 extends greatly in the direction intersecting (orthogonal to) the horizontal rotation shaft 23, and it is this gate bar 24 that actually blocks the roadway 2. The gate bar 24 includes a gate bar holding portion 25 located on one end side thereof and a gate bar main body 26 located on the other end side, and is formed by mounting the gate bar main body 26 on the gate bar holding portion 25. The gate bar main body 26 is formed by covering the other end side of a core portion 27 formed of a lightweight material, for example, an aluminum hollow pipe, with a cushioning material 28 formed of foamed urethane or the like. In addition, a laminate such as red and white stripes is applied to the outer surface portion of the cushioning material 28 in order to improve visibility from a driver or the like.

  Further, as shown in FIG. 2A, the gate bar base portion 21 and the gate bar 24 function to integrally fix the gate bar base portion 21 and the gate bar 24 so that they face the same direction when the roadway opening / closing operation is performed. It has. Furthermore, when the vehicle collides with the gate bar 24 that blocks the roadway 2, the gate bar base 21 and the gate bar 24 unlink and fix the gate bar base 21 and the gate bar 24, as shown in FIG. 2 (2). A function of rotating the gate bar 24 with respect to the gate bar base portion 21 is provided. Here, when the vehicle collides with the gate bar 24 that cuts off the roadway 2, as shown in FIG. 2 (2), the gate bar base 21 and the gate bar 24 are unintegrated and fixed, and the gate bar base 21 is fixed. The operation of rotating the gate bar 24 is referred to as “release operation”. These two functions of the gate bar base 21 and the gate bar 24 are realized by a connection structure of both described below.

  That is, as shown in FIG. 2 (1), the other end of the gate bar holding portion 25 located at the intermediate portion of the gate bar 24 can be rotated to the other end side of the gate bar base portion 21 via the release rotation shaft 29. It is supported. The release rotation shaft 29 is an axis extending in a direction intersecting with the extending direction of the gate bar base portion 21 (in the present embodiment, a direction orthogonal to the extending direction of the gate bar base portion 21). As shown in FIG. 2 (2), the gate bar 24 can rotate around the release rotation shaft 29. One end side of the gate bar 24 is detachably held on one end side of the gate bar base portion 21. Specifically, a locking mechanism 31 is provided on one end side of the gate bar base portion 21 and one end side of the gate bar 24, and the one end side of the gate bar base portion 21 and the one end side of the gate bar 24 are mutually connected by the locking mechanism 31. It is detachably locked. As shown in FIG. 2 (1), a torsion spring 32 as a release urging portion is provided in the vicinity of the release rotation shaft 29 in the gate bar base 21. As shown by the arrow A in FIG. 2B, the torsion spring 32 applies a biasing force to the gate bar 24 so as to promote the rotation of the gate bar 24 in the release operation direction during the release operation.

  On the other hand, as shown in FIG. 1, a gate bar drive unit 33 that rotates the gate bar base 21 around the horizontal rotation shaft 23 is provided in the rotation housing 16 of the rotation unit 15. As will be described later, the gate bar driving unit 33 includes a gate bar driving motor 71 (see FIG. 10) and the like. As shown in FIG. 3, the gate bar base 21 is rotated by the gate bar driving unit 33 while the rotating unit 15 is positioned so that the horizontal rotating shaft 23 extends in the front-rear direction. A road opening / closing operation can be performed. Here, the “road opening / closing operation” means that the gate bar base 21 and the gate bar 24 are lying on the side and upright while the rotating portion 15 is positioned so that the horizontal rotating shaft 23 extends in the front-rear direction. This is an operation for blocking / opening the road 2. As shown in FIG. 3 (1), when the gate bar base portion 21 is laid down by the gate bar driving unit 33, the gate bar 24 is laid down together with the gate bar base portion 21, thereby blocking the roadway 2. Hereinafter, the position where the gate bar base 21 and the gate bar 24 lie down is referred to as a “side-down position”. On the other hand, as shown in FIG. 3 (2), when the gate bar base 21 is brought upright by the gate bar driving unit 33, the gate bar 24 is brought upright together with the gate bar base 21, thereby opening the roadway 2. Hereinafter, the position where the gate bar base and the gate bar stand upright in this way is referred to as “upright position”.

  Further, as shown in FIG. 2B, the gate device 1 includes a stopper portion 35 that supports the gate bar 24 in a released state. As shown in FIG. 1, the stopper part 35 is provided on the left side of the rear surface of the main body part 11. The stopper portion 35 includes a rod-like stopper arm 36. One end side of the stopper arm 36 is supported by the main body 11 via the bracket 37 and the connecting shaft 38, so that the stopper arm 36 has a limited range (for example, a range indicated by R in FIG. 2 (1)). In the horizontal direction. A receiving portion 39 is provided on the other end side of the stopper arm 36, and the receiving portion 39 is formed by covering the core portion with a cushioning material made of, for example, urethane foam. As shown in FIG. 2A, the bracket 37 is provided with a stopper spring 40 as a pressing force generating portion. The stopper spring 40 presses the other end side of the gate bar 24 in the released state in the reverse direction (the direction indicated by the arrow B in FIG. 2 (2)) with respect to the release operation direction via the stopper arm 36. Here, the biasing force of the stopper spring 40 is larger than the biasing force of the torsion spring 32 provided in the vicinity of the release rotation shaft 29 of the gate bar base 21.

  4 to 6 show the return operation of the gate device 1. Here, the “returning operation” is an operation of returning the released gate bar 24 to the state before the releasing operation, that is, the original state in which the road opening / closing operation is possible. Hereinafter, the release operation and the return operation of the gate device 1 will be described with reference to FIGS. 2 and 4 to 6.

  As shown in FIG. 2 (1), the gate bar base portion 21 and the gate bar 24 are placed in the recumbent position while the rotation portion 15 is positioned so that the horizontal rotation shaft 23 extends in the front-rear direction. 2 is blocked. Hereinafter, the horizontal rotation shaft 23 is positioned so as to extend in the front-rear direction, and a predetermined position of the rotation unit 15 that can block the roadway 2 by the gate bar 24 by lying down the gate bar 24 is referred to as “roadway”. It is called a “blockable position”. In a normal state, the vehicle does not collide with the gate bar 24 blocking the roadway 2 in this way. However, for example, when a vehicle passing through the ETC gate forgets to insert an ETC card into the ETC on-board device, or when the vehicle enters without waiting for the gate bar 24 to open from the parking lot exit intentionally or accidentally, etc. In an abnormal state, the vehicle may collide with the gate bar 24 blocking the roadway 2.

  When a vehicle traveling on the road 2 collides with the gate bar 24 blocking the road 2, the vehicle collides with the other end of the gate bar 24 (the other end of the gate bar main body 26). When the vehicle collides with the gate bar 24 in this way, the locking mechanism 31 is unlocked by the force applied to the other end side of the gate bar 24 due to the collision, and the one end side (gate bar 24) of the gate bar 24 from one end side of the gate bar base 21. One end side of the holding portion 25 is detached. Then, the gate bar 24 rotates around the release rotation shaft 29 in the traveling direction of the vehicle, and hits the receiving portion 39 of the stopper arm 36 and stops as shown in FIG. In the present embodiment, the gate bar 24 rotates approximately 90 degrees clockwise and stops. The direction of the gate bar 24 stopped in this way is substantially parallel to the roadway 2. At this time, when the force applied to the other end side of the gate bar 24 due to the collision is small, the gate bar 24 has a force caused by the collision and a torsion spring 32 provided in the vicinity of the release rotation shaft 29 (see FIG. 2 (1)). ) By the urging force, and hits the receiving portion 39 of the stopper portion 35 with a relatively weak force to stop. Thus, according to the torsion spring 32, the gate bar 24 that performs the release operation can surely and quickly reach the receiving portion 39 of the stopper portion 35, and the gate bar 24 hits the receiving portion 39 of the stopper portion 35 and is stopped. The state can be maintained. On the other hand, when the force applied to the other end side of the gate bar 24 due to the collision is large, the gate bar 24 rotates vigorously by the force due to the collision and hits the receiving portion 39 of the stopper portion 35 with a relatively strong force. The impact received by the receiving portion 39 is absorbed by the stopper spring 40 (see FIG. 2 (1)) and the cushioning material of the receiving portion 39. Thus, according to the stopper spring 40, the impact of the gate bar 24 hitting the receiving portion 39 can be reduced.

  Such a release operation of the gate bar 24 is detected by a release detection switch 77 (see FIG. 10) as will be described later, and in response thereto, the return operation is automatically started immediately by the control unit 81 (see FIG. 10). The In the return operation, first, as shown in FIG. 2 (3) or FIG. 4 (2), the rotation unit 15 follows the rotation during the release operation of the gate bar 24 by driving the rotation drive unit 18 (or Rotate to follow. In the present embodiment, the rotation unit 15 rotates about 90 degrees clockwise from the position where the road can be blocked. In this way, while the rotating portion 15 rotates, the gate bar 24 slides backward while maintaining the contact between the gate bar 24 and the receiving portion 39 of the stopper portion 35, and one end side of the gate bar base portion 21 is at the gate bar 24. Approaches one end side (one end side of the gate bar holding portion 25).

  As shown in FIG. 2 (3) or FIG. 4 (2), the other end side of the gate bar 24 moves slightly in the direction away from the roadway 2 while the rotating portion 15 rotates, and the orientation of the gate bar 24 However, if the other end of the gate bar 24 interferes with another device installed on the island 3, the stopper arm 36 is formed long. The receiving portion 39 is brought into contact with a position close to the other end of the gate bar 24. Thereby, since the amount by which the other end side of the gate bar 24 moves away from the roadway 2 can be reduced, it is possible to prevent the other end of the gate bar 24 from interfering with other devices.

  Subsequently, as shown in FIG. 2 (4) or FIG. 5 (1), the rotating portion 15 is moved to a predetermined position where one end of the released gate bar 24 can be locked to one end of the gate bar base 21. Is rotated, the rotation unit 15 stops. Hereinafter, a predetermined position of the rotating portion 15 when the rotating portion 15 is rotated and locked (held) with one end side of the released gate bar 24 to one end side of the gate bar base portion 21 is referred to as a “gate bar pick-up position”. . In this embodiment, the rotation part 15 reaches | attains a gate bar pick-up position, when it rotates about 90 degree | times clockwise from the position which can interrupt a roadway.

  In the present embodiment, when the rotating unit 15 reaches the gate bar reception position, the rotating unit 15 presses one end side of the gate bar base 21 and one end side of the gate bar 24 in the clockwise direction. Since the force of the rotation drive unit 18 that rotates the rotation unit 15 to the gate bar reception position is larger than the biasing force of the stopper spring 40 of the stopper unit 35, the gate bar 24 is attached to the stopper spring 40 of the stopper unit 35. Slightly turns clockwise against the forces. Thereby, the receiving part 39 of the stopper part 35 is pushed by the other end side of the gate bar 24 and moves slightly in the direction away from the roadway 2. As a result, the force of the rotation driving unit 18 and the force of the stopper spring 40 that are opposite to each other act on one end side of the gate bar base portion 21 and one end side of the gate bar 24, so that one end side of the gate bar base portion 21 and the gate bar 24 It is strongly pushed in the direction in which the one end side approaches or contacts each other. Thereby, the locking mechanism 31 provided on one end side of the gate bar base 21 and one end side of the gate bar 24 is securely locked to each other. By the locking at this time, the gate bar base portion 21 and the gate bar 24 are integrally fixed so that both face the same direction.

  Subsequently, as shown in FIG. 5B, the gate bar base 21 and the gate bar 24 are rotated upward by the drive of the gate bar driving unit 33. While rotating upward, the direction of the integrally fixed gate bar base 21 and gate bar 24 remains parallel to the roadway 2. When the other end side of the gate bar 24 is separated from the receiving portion 39 of the stopper portion 35 due to the upward rotation of the gate bar 24, the force applied to the receiving portion 39 from the rotation driving portion 18 is interrupted. Move slightly in the direction approaching the roadway 2 and return to the original position. Further, by driving the gate bar driving unit 33, the gate bar base 21 and the gate bar 24 continue to rotate upward and stop when they reach the upright position as shown in FIG. Subsequently, the rotation drive unit 18 drives the rotation unit 15 to rotate in a direction opposite to the traveling direction of the vehicle (the release operation direction of the gate bar 24), for example. Then, as shown in FIG. 6 (2), the rotation of the rotation unit 15 stops when the rotation unit 15 reaches the position where the roadway can be blocked. In the present embodiment, the rotating portion 15 rotates approximately 90 degrees counterclockwise and reaches the roadway blocking possible position. Thus, when the rotation part 15 arrives at the position where the road can be interrupted, the position of the gate bar 24 is the same as the position of the gate bar 24 when the road 2 is opened in the road opening / closing operation, so that the return is continued. The operation may be completed or the return operation may be completed after the gate bar 24 is rotated to the recumbent position. When the return operation is completed after the gate bar 24 is turned to the recumbent position, whether or not there is a vehicle passing through the gate for safety before the gate bar 24 is finally turned to the recumbent position. The gate bar 24 is rotated to the recumbent position only when there is no vehicle passing through the gate. This control will be described later.

  According to the gate device 1 according to the embodiment of the present invention, the space required for the gate bar 24 to move for returning can be reduced. That is, in the gate device according to the prior art described in Patent Document 1, the blocking bar that is bent due to the collision of the vehicle remains above the blocking bar driving device that is installed in the middle in the left-right direction of the island while being bent. Then, the blocking bar is rotated upward so as to stand upright. In this prior art gate device, the blocking bar pivots upward in the middle part of the island in the left-right direction, so it is necessary to secure a large space above the middle part in the left-right direction of the island. As a result, when installing other devices on the island, the installation location is greatly limited. On the other hand, in the gate device 1 according to the embodiment of the present invention, the gate bar 24 that is oriented substantially parallel to the road 2 near the boundary between the road 2 and the island 3 is first rotated upward so as to stand upright. Thereafter, the upright gate bar 24 is moved to the intermediate portion in the left-right direction of the island 3 by the rotation of the rotation unit 15. As a result, the gate bar 24 rotates upward in the vicinity of the boundary between the roadway 2 and the island 3, so that it is not necessary to secure a wide space above the intermediate portion in the left-right direction of the island 3. Therefore, when installing another device on the island 3, the restriction on the installation location can be reduced.

  On the other hand, in the case where the passage of the vehicle can be restricted so that the vehicle does not pass through the gate from the release operation of the gate bar 24 to the completion of the return operation, in the gate device 1 according to the embodiment of the present invention. The following return operation may be performed.

  That is, when the release operation of the gate bar 24 is detected by the release detection switch 77 and the return operation is automatically started by the control unit 81, first, as shown in FIG. 2 (3) or FIG. The moving unit 15 is rotated by the drive of the rotation driving unit 18 so as to follow (or follow) the rotation of the gate bar 24 during the release operation. Subsequently, as shown in FIG. 2 (4) or FIG. 5 (1), the rotating unit 15 reaches the gate bar reception position and stops. At this time, the locking mechanism 31 provided on one end side of the gate bar base portion 21 and one end side of the gate bar 24 is locked to each other, and the gate bar base portion 21 and the gate bar 24 are integrally fixed. Subsequently, the rotation drive unit 18 drives the rotation unit 15 to rotate in the direction opposite to the traveling direction of the vehicle (the release operation direction of the gate bar 24) from the gate bar reception position to the position where the road can be blocked. Reach and stop. This completes the return operation. While the rotating part 15 rotates from the gate bar picking position to the roadway blocking position, the integrally fixed gate bar base 21 and gate bar 24 remain in the lying position. When the turning unit 15 reaches the road blocking position, the gate bar base 21 and the gate bar 24 are positioned as shown in FIG. 3 (1), that is, the gate bar when the road 2 is blocked in the road opening / closing operation. It becomes the same as position 24.

  In this return operation, the gate bar 24 is rotated on the road 2 while being in the recumbent position, so that the road 2 is blocked by the gate bar 24 during the return operation. However, since this returning operation is adopted when the vehicle can be restricted so that the vehicle does not pass through the gate, the returning operation is usually performed even if the gate bar 24 during the returning operation blocks the roadway 2. The vehicle does not collide with the operating gate bar 24. However, when any abnormal situation occurs, it cannot be said that there is no possibility that the vehicle will collide with the gate bar 24 during the return operation. However, even if the vehicle collides with the returning gate bar 24 in the event of an abnormal situation, according to the gate device 1 according to the embodiment of the present invention, the gate bar 24 and other parts of the gate device 1 (for example, It is possible to prevent the gate bar holding part 25, the turning part 15, the main body part 11 and the like from being damaged.

  That is, in the gate device 1, the gate bar base portion is engaged with the one end side of the gate bar base portion 21 and the one end side of the gate bar 24 by the locking mechanism 31 when the rotating portion 15 rotates to the gate bar receiving position. 21 and the gate bar 24 are integrally fixed, and then the rotating portion 15 is rotated from the gate bar reception position to the position where the roadway can be blocked. As a result, the gate bar base 21 and the gate bar 24 that are integrally fixed to each other move forward in the horizontal direction. When the vehicle collides with the other end of the gate bar 24 while the gate bar base 21 and the gate bar 24 are moving in this way, the force of the collision causes the engagement between one end of the gate bar base 21 and one end of the gate bar 24. The stop is released, and the integrated fixing of the gate bar base 21 and the gate bar 24 is released. As a result, the gate bar 24 rotates about the release rotation shaft 29, the other end side of the gate bar 24 moves rearward, quickly leaves the vehicle, and the impact of the collision is released. Thus, the gate bar 24 during the return operation can perform the release operation in the same manner as the gate bar 24 when the road 2 is blocked in the road opening / closing operation. Even if they collide, it is possible to prevent the gate bar 24 and other parts of the gate device 1 from being damaged. Further, the damage caused to the vehicle by the collision with the gate bar 24 can be reduced or substantially eliminated.

7 to 9 specifically show the locking mechanism 31 provided on one end side of the gate bar base 21 and one end side of the gate bar 24. That is, FIG. 7 (1) shows a portion where the locking mechanism 31 is provided in the gate device 1 and its peripheral portion, and FIG. 7 (2) is an enlarged view of the locking mechanism 31 in FIG. 7 (1). FIG. 7 (3) shows the locking mechanism 31 in a state where the locking is released. 8 (1) is a cross-sectional view of the locking mechanism 31 and its peripheral portion, and FIG. 8 (2) shows the locking movable part 52 and the latch in the locking mechanism 31 in FIG. 8 (1). 61 is shown enlarged. 9 (1) to 9 (4) show the operation of the locking mechanism 31, and each of FIGS. 9 (1) to 9 (4) is an enlarged view of a portion surrounded by a two-dot chain line in the drawing on the right side. Is shown on the left side.
As shown in FIG. 7 (1) or FIG. 7 (2), the gate bar base portion 21 is formed in a U-shaped cross section, and a wall portion 22 is provided at one end portion. Further, the gate bar holding portion 25 constituting one end side of the gate bar 24 is formed by a long member having a U-shaped cross section that is narrower than the gate bar base portion 21 so as to be able to enter the recess of the U-shaped gate bar base portion 21. Is formed. In addition, one end side of the core portion 27 of the gate bar body 26 is mounted and fixed in the recess of the gate bar holding portion 25 having a U-shaped cross section.

  Further, as shown in FIG. 7 (3) or FIG. 8 (1), the locking mechanism 31 is provided on one end side of the gate bar base portion 21 and one end side of the gate bar holding portion 25. That is, the locking base 51 is fixed to one end side of the gate bar base 21, and the locking movable part 52 is connected to the locking base 51 via the locking shaft 53 as indicated by arrows C and D in FIG. It is supported so as to be rotatable in the direction. Further, as shown in FIG. 8 (1), a screw hole 54 is formed in the locking base 51 and a bolt support portion 55 is integrally formed, and an adjustment bolt 56 is formed in the bolt support portion 55 and the screw hole 54. It is attached. Further, a through hole 57 is formed in the locking movable portion 52, and the adjustment bolt 56 is inserted into the through hole 57 through a gap. Further, an adjustment spring 58 is attached around the adjustment bolt 56, and the adjustment spring 58 presses the locking movable portion 52 in the direction indicated by the arrow D in FIG. Further, as shown in FIG. 8 (1), an adjustment hole 59 is formed in the wall portion 22 of the gate bar base portion 21. A wrench can be inserted from the adjustment hole 59 and the adjustment bolt 56 can be rotated to advance and retreat, whereby the force for pressing the locking movable portion 52 by the adjustment spring 58 can be adjusted.

  On the other hand, on one end side of the gate bar holding portion 25, a latch 61 is supported via a latch shaft 62 so as to be rotatable in directions indicated by arrows E and F in FIG. The latch 61 is urged in the direction of arrow F by a latch spring 63 provided in the vicinity of the latch 61, so that the abutment portion 64 formed on the latch 61 has a latch 61 movable portion. Except when the operation of locking to 52 is performed, it is in contact with a latch base shaft 65 fixed to one end of the gate bar holding portion 25. The force with which the latch spring 63 biases the latch 61 is significantly smaller than the force with which the adjustment spring 58 presses the locking movable portion 52.

  The locking of the locking mechanism 31 is realized by locking the locking movable part 52 and the latch 61. When the vehicle collides with the other end side of the gate bar 24 and the locking mechanism 31 is unlocked, the locking movable portion 52 is shown by the arrow in FIG. Rotating in the C direction, the latch 61 is detached from the locking movable portion 52. Here, the integrated fixing of the gate bar base 21 and the gate bar 24 must be prevented from being released by the gate device 1 simply opening and closing the roadway, and is released by the wind blowing on the gate bar 24. It is necessary not to be done. On the other hand, the integrated fixing of the gate bar base 21 and the gate bar 24 needs to be released immediately when the vehicle collides with the other end of the gate bar 24. The strength of the integrated fixing of the gate bar base 21 and the gate bar 24 is determined by the locking strength of the locking mechanism 31. Specifically, the strength of the adjustment spring 58 pressing the locking movable portion 52 is determined. Dependent. Therefore, the magnitude of the force with which the adjustment spring 58 presses the locking movable portion 52 is determined when the gate bar base portion 21 and the gate bar 24 should be maintained and fixed as described above. It is set considering the case. Specifically, it is desirable that the force with which the adjustment spring 58 presses the locking movable portion 52 is as small as possible, so that the integrated fixing cannot be released without permission by wind or the road opening / closing operation. Of course, even if the force by which the adjustment spring 58 presses the locking movable portion 52 is made as small as possible as long as the integrated fixing is not released by the wind or the roadway opening / closing operation, the long gate bar 24 is at its one end. Considering that the structure is locked, it is necessary to set the force by which the adjustment spring 58 presses the locking movable portion 52 to be considerably large, and the locking movable portion 52 to which such a large force is applied, The latch 61 is desirably formed of a metal material having high wear resistance. For example, the latch 61 is preferably formed of a combination of an iron-based sintered alloy and a copper-based sintered alloy.

  On the other hand, when the rotation portion 15 moves to the gate bar reception position and the locking mechanism 31 is locked, the latch 61 is rotated and locked as shown in FIGS. 9 (1) to (4). Get over the claw 52A formed at the tip of the part 52. That is, when the return operation is started and the rotating portion 15 rotates and approaches the gate bar reception position, one end side of the gate bar 24 (one end side of the gate bar holding portion 25) approaches one end side of the gate bar base portion 21. 9 (1), the latch 61 comes into contact with the claw portion 52A of the locking movable portion 52. At this stage, the latch 61 maintains a posture in which the contact portion 64 is in contact with the latch base shaft 65. Subsequently, as shown in FIG. 9 (2), when the rotating portion 15 further approaches the gate bar reception position, the latch 61 is pushed by the claw portion 52 </ b> A of the locking movable portion 52 and resists the urging force of the latch spring 63. Then, it turns and tries to get over the claw portion 52A. Subsequently, as shown in FIG. 9 (3), when the rotating portion 15 reaches the gate bar reception position, the latch 61 completely gets over the claw portion 52 </ b> A of the locking movable portion 52. Then, the latch 61 returns to the posture in which the contact portion 64 is in contact with the latch base shaft 65. As a result, the latch 61 and the latching movable portion 52 are latched. 9 (3) shows a state where the other end side of the gate bar 24 is pressed to the left by the receiving portion 39 of the stopper portion 35 when the rotating portion 15 reaches the gate bar receiving position (FIG. 2 (4)). ) Or FIG. 5 (1)). As a result of the other end side of the gate bar 24 being pressed leftward by the receiving portion 39, one end side of the gate bar 24 (one end side of the gate bar holding portion 25) is deeply inserted into the recess of the gate bar base portion 21. Thereafter, the returning operation continues, and the gate bar base 21 and the gate bar 24, which are integrally fixed, start to rotate toward the upright position, and the other end side of the gate bar 24 moves away from the receiving portion 39 of the stopper portion 35 (FIG. 5). As shown in FIG. 9 (4), the position of the gate bar 24 relative to the gate bar base 21 is determined by the urging force of the torsion spring 32 provided in the vicinity of the release rotation shaft 29. That is, the latch 61 comes into contact with the inside of the claw portion 52A of the latching movable portion 52, and the gate bar base portion 21 and the gate bar 24 are parallel to each other.

  Here, when the magnitudes of the urging forces of the respective parts described in the present embodiment are compared with the moments around the release rotation shaft 29 and are listed in descending order, (1) the rotation unit 15 (the rotation drive unit 18). (2) Moment due to wind pressure received by the gate bar 24, (4) Moment due to the stopper 39 receiving portion 39 (stopper spring 40) (5) Moment by the torsion spring 32 provided in the vicinity of the release rotation shaft 29, and (6) Moment by the urging force of the latch spring 63 of the locking mechanism 31. However, since (4) differs from (2) and (3) in the state in which it acts and the direction, it does not have to be limited in particular in order of magnitude.

  FIG. 10 shows a configuration for electrically controlling the operation of the gate device 1. As shown in FIG. 10, the gate device 1 includes a gate bar drive motor 71 that rotates the gate bar base 21, a first limit detection switch 72 that detects that the gate bar base 21 or the gate bar 24 has reached the recumbent position, The second limit detection switch 73 that detects that the gate bar base 21 or the gate bar 24 has reached the upright position, the rotation drive motor 74 that rotates the rotation unit 15, and the rotation drive motor 74 can block the road. The third limit detection switch 75 for detecting that the position has been reached, the fourth limit detection switch 76 for detecting that the rotation drive motor 74 has reached the gate bar reception position, and the gate bar base 21 and the gate bar 24 are integrated. Release detection switch 77 for detecting the establishment / release of the lock and a control program for right installation described later A setting operation unit 78 that enables switching between a ram and a control program for left installation, a communication unit 79 that communicates with a roadway control panel and the like, and an electric signal from an external device is input via a cable, or An input / output unit 80 that outputs an electrical signal to an external device and a control unit 81 that controls the operation of the gate device 1 are provided.

  Each of the rotation drive motor 74 and the gate bar drive motor 71 is, for example, a DC motor. The release detection switch 77 is attached, for example, in the horizontal rotation shaft hole 66 shown in FIG. 7 (3), and is turned OFF when the gate bar base portion 21 and the gate bar holding portion 25 sufficiently approach or come into contact with each other. Sometimes it turns ON. The setting operation unit 78 is a dip switch, for example, and is provided in the main body housing 12. The communication unit 79 is provided in the main body housing 12 and receives vehicle data sent from the ETC antenna to the road control panel when the gate device 1 is installed in the ETC gate, for example. The input / output unit 80 is provided in the main body housing 12, and the input / output unit 80 receives, for example, a vehicle detection signal output from the vehicle detector when the gate device 1 is installed at the entrance / exit of the parking lot. Is done. The control unit 81 is provided in the main body casing 12 and includes a CPU (Central Processing Unit), a memory, and the like, and the memory stores a control program for right installation and a control program for left installation. The control unit 81 is a specific example of a drive control unit.

  FIG. 11 shows the control of the return operation of the gate device 1 executed by the control unit 81 in FIG. The control of the return operation is realized by a control program for right installation. In FIG. 11, when the vehicle collides with the other end of the gate bar 24 that is in the recumbent position and blocks the road 2 during the opening / closing operation of the gate device 1, the gate bar 24 performs a release operation. The integrated fixing of the base 21 and the gate bar 24 is released. When the integrated fixing of the gate bar base 21 and the gate bar 24 is released, the release detection switch is turned on (step S1: YES). When the release detection switch is turned on, the control unit 81 drives the rotation drive motor 74 to rotate forward (step S2). By the normal rotation of the rotation drive motor 74, the rotation unit 15 at the position where the road can be blocked rotates in the vehicle traveling direction (the release operation direction of the gate bar 24). Subsequently, when the rotation unit 15 reaches the gate bar reception position, the fourth limit detection switch 76 is turned on (step S3: YES). Further, at this time, when the rotating portion 15 reaches the gate bar pick-up position, the gate bar 24 is locked to the gate bar base portion 21, and the integrated fixing is established therebetween, and the release detection switch 77 is turned OFF (step S4). : YES) Immediately after this, the controller 81 stops the rotation drive motor 74 (step S5). Subsequently, the control unit 81 causes the gate bar drive motor 71 to rotate forward (step S6). By the normal rotation of the gate bar drive motor 71, the gate bar base portion 21 and the gate bar 24 in the recumbent position rotate toward the upright position. Subsequently, when the gate bar base 21 or the gate bar 24 reaches the upright position, the second limit detection switch 73 is turned on (step S7: YES). Immediately after this, the controller 81 stops the gate bar drive motor 71 (step S8). Subsequently, the control unit 81 reversely rotates the rotation drive motor 74 (step S9). Due to the reverse rotation of the rotation drive motor 74, the rotation portion 15 at the gate bar reception position rotates in the direction opposite to the traveling direction of the vehicle (the release operation direction of the gate bar 24). Subsequently, when the rotating unit 15 reaches the roadway blocking position, the third limit detection switch 75 is turned on (step S10: YES). Immediately after this, the control part 81 stops the rotation drive motor 74 (step S11). Subsequently, the control unit 81 determines whether or not the roadway 2 can be blocked (step S12). For example, the control unit 81 receives a signal indicating that the vehicle cannot be blocked or the vehicle is approaching from the road control panel via the communication unit 79, or the vehicle is passing from the vehicle detector via the input / output unit 80. When the vehicle detection signal indicating that the signal is received is determined, it is determined that blocking is impossible, and when such a signal is not received, it is determined that blocking is possible. If it is determined that the roadway 2 can be blocked (step S12: YES), the control unit 81 reversely rotates the gate bar drive motor 71 (step S13). By the reverse rotation of the gate bar drive motor 71, the gate bar base 21 and the gate bar 24 in the upright position rotate toward the recumbent position. Subsequently, when the gate bar base 21 or the gate bar 24 reaches the recumbent position, the first limit detection switch 72 is turned on (step S14: YES). Immediately after this, the controller 81 stops the gate bar drive motor 71 (step S15). This completes the return operation.

  12 and 13 show a gate device 101 according to another embodiment of the present invention. Specifically, FIG. 12 shows a state in which the gate device 101 assembled for right installation and the gate device 101 assembled for left installation are respectively arranged on both sides of the roadway 2. FIG. 13 shows a structure of a gate device 101 that can selectively realize both the right-installation gate device and the left-installation gate device by changing the assembly method. Hereinafter, such a structure of the gate device 101 is referred to as “a left-right shared structure”. The configuration and operation of the gate device 101 other than the left-right shared structure are the same as those of the gate device 1 described above.

  A specific left-right shared structure of the gate device 101 is as follows. That is, as shown in FIG. 13, the main body housing 12 is formed in a symmetrical rectangle when viewed from above. The main body housing 12 has a left surface 12A and a right surface 12B extending in a direction parallel to the roadway 2, and the vertical rotation shaft 17 has a distance from the left surface 12A of the main body housing 12 to the vertical rotation shaft, The distance from the right surface 12 </ b> B of the main body housing 12 to the vertical rotation axis is set to be equal to each other. In the present embodiment, the vertical rotation shaft 17 is disposed at the center of the main body housing 12 when the main body housing 12 is viewed from above. Further, when viewed from above, the rotating housing 16 is also formed in a bilaterally symmetric rectangle like the main body housing 12. Further, the rotating housing 16 has a left surface 16A and a right surface 16B that expand in a direction parallel to the road 2 when the rotating portion 15 is positioned so that the horizontal rotation shaft 23 is parallel to the road 2. The horizontal rotation shaft 23 has a distance from the left surface 16A of the rotation housing 16 to the horizontal rotation shaft 23 and a distance from the right surface 16B of the rotation housing 16 to the horizontal rotation shaft 23. They are placed at equal positions. Thus, the main body 11, the rotation unit 15, the vertical rotation shaft 17, and the horizontal rotation shaft 23 all have a symmetrical structure or arrangement.

  Furthermore, the gate bar base 21 is detachably attached to a flange 82 fixed to the tip of the horizontal rotation shaft 23 with a screw. Further, the shape of the flange 82 and the position of the screw hole are set so that the gate bar base portion 21 described later can be rearranged. The rotating unit 15 is detachably attached to a flange 83 fixed to the tip of the vertical rotating shaft 17 with a screw. In addition, the shape of the flange 83 and the position of the screw hole are set so that the rotation unit 15 described later can be replaced. The bracket 37 of the stopper portion 35 is detachably attached to the rear surface 12C of the main body housing 12 with screws. In addition, a plurality of screw holes (not shown) are provided on the rear surface 12C of the main body housing 12 in order to enable replacement of a stopper portion 35 described later. Further, in the stopper portion 35, the receiving portion 39 is detachably attached to the stopper arm 36 with screws, and the stopper arm 36 can be switched between right installation and left installation by reversing the direction. It has a structure.

  The memory of the control unit 81 stores a control program for left installation and a control program for right installation. A control program for left installation and a control for right installation are controlled by a dip switch of the setting operation unit 78. One of the programs can be selected. By switching the control program for the right installation to the control program for the left installation, or switching the control program for the left installation to the control program for the right installation, the forward rotation direction and the reverse rotation direction of the gate bar drive motor 71 are reversed.

Further, the receiving portion 39 is removed from the stopper arm 36 in the stopper portion 35. Subsequently, the attachment angle of the rotation unit 15 is shifted by 90 degrees, and the rotation unit 15 is attached to the vertical rotation shaft 17. Subsequently, the mounting angle of the gate bar base 21 is shifted by 90 degrees, and the gate bar base 21 is mounted on the horizontal rotation shaft 23. Further, the direction of the stopper arm 36 is reversed, and the receiving portion 39 is attached to the stopper arm 36 so that the receiving portion 39 protrudes upward. Subsequently, the stopper portion 35 assembled in this way is attached to the right side of the rear surface 12 </ b> C of the main body housing 12. Subsequently, the DIP switch of the setting operation unit 78 is switched.

  As described above, since the gate device 101 according to another embodiment of the present invention has a left-right shared structure, one gate device 101 can be used for both right installation and left installation. Points, manufacturing costs, and operational costs can be reduced.

  In the above-described embodiment, the case where the main body 11 is provided with the stopper portion 35 that supports the gate bar 24 that has been released has been described as an example, but the present invention is not limited thereto. A separate stopper portion independent of the main body portion 11 may be installed behind the main body portion 11. Moreover, it is good also as a structure which supports the gate bar 24 which carried out release operation | movement by using the other apparatus located behind the main-body part 11 as a stopper part, and making the gate bar 24 which carried out release operation contact | abut to the said other apparatus.

  In the above-described embodiment, a DC motor is used as the rotation drive motor 74 and the gate bar drive motor 71, and limit detection switches 72, 73, 75, and 76 are used as means for detecting the positions of the rotation unit 15 and the gate bar 24. Although the case has been described as an example, the present invention is not limited to this. A stepping motor may be used as the rotation drive motor 74 or the gate bar drive motor 71, and the position control of the rotation unit 15 or the gate bar 24 may be performed by phase control of the stepping motor.

  In addition, the present invention can be appropriately changed without departing from the spirit or idea of the invention which can be read from the claims and the entire specification, and a gate device accompanied by such a change is also included in the technical idea of the present invention. included.
