Description

  The present invention relates to a start control device for controlling the start of a vehicle.

An ETC (registered trademark) lane or the like installed in a place such as a toll gate on an expressway is provided with a start control device for controlling the start of the vehicle.
The start control device informs the driver of the vehicle whether the passage of the vehicle is permitted or not by opening and closing a bar called a blocking bar.

If the blocking rod is in a closed position where the vehicle is not permitted to pass, if the vehicle passes, the vehicle will collide with the blocking rod. In order to reduce the damage of the start control device due to this collision, there is one in which the blocking rod is also rotated in the traveling direction of the vehicle.
Patent Document 1 describes a mechanism for returning the original position to the original position when the blocking bar rotates in the traveling direction of the vehicle due to the collision of the vehicle. In Patent Document 1, when the blocking bar is opened in a state where the blocking bar is rotated in the traveling direction of the vehicle, the blocking bar is returned to the original position by the guide bar.

In the configuration of Patent Document 1, if the vehicle collides with the blocking bar during the opening / closing operation of the blocking bar, the bar holder at the base of the blocking bar may hit the guide bar and damage the start control device.
An object of the present invention is to reduce damage to the start control device when a bar holder hits a guide bar.

The start control device according to the present invention includes:
A blocking rod is attached to the housing so as to be pivotable about a drive shaft between a closed position where vehicle passage is not permitted and an open position where vehicle passage is permitted. A bar holder that is pivotably mounted about a rotation axis perpendicular to the drive shaft between an operation position for performing the operation and a retracted position in which the blocking bar is retracted;
When the blocking bar is in the retracted position, when the blocking bar is rotated about the drive shaft from the closed position toward the open position, the blocking bar comes into contact with the bar holder and the blocking bar is moved to the open position. A guide bar that rotates from the retracted position to the operating position;
And an impact mitigating portion for mitigating an impact applied to the guide bar when the blocking bar rotates from the operating position toward the retracted position.

Embodiment 1 FIG.
*** Explanation of configuration ***
The configuration of the start control device 10 according to the first embodiment will be described with reference to FIGS. 1 to 4.
The start control device 10 includes a housing 1, a blocking bar 2, a bar holder 3, a guide bar 4, and an impact relaxation unit 5.

  The casing 1 is installed in a place such as on the road at the end of a traffic lane through which the vehicle 20 passes. The housing 1 is a rectangular parallelepiped box.

  The blocking bar 2 is a bar attached to the housing 1 via the bar holder 3. The blocking bar 2 is used to indicate to the driver of the vehicle 20 whether or not passage of the traffic lane is permitted.

The bar holder 3 is attached to the front side of the housing 1 so as to rotate around the shaft 8 as a drive shaft (in the Z1 direction in FIGS. 1 and 3) by the power of the drive unit 7. Further, the bar holder 3 is bent about 90 degrees around the rotation axis perpendicular to the axial direction of the shaft 8 (Z2 direction in FIGS. 1 and 4) at the movable portion 31 portion. As a result, the bar holder 3 attaches the blocking bar 2 to the housing 1 so as to be rotatable about the shaft 8 between the closed position C and the open position O (see FIG. 3). It is attached so as to be rotatable in the axial direction of the shaft 8 between the retracted position V (see FIG. 4).
The closed position C is the position of the blocking bar 2 drawn by a solid line in FIGS. 1 and 3 and indicates that the passage of the vehicle 20 is not permitted. The open position O is the position of the blocking bar 2 drawn in broken lines in FIGS. 1 and 3 and indicates that the vehicle 20 is allowed to pass. The operation position U is the position of the blocking bar 2 drawn with a solid line in FIGS. 1 and 4, and is a position where the vehicle 20 is blocked and allowed to pass. The retracted position V is the position of the blocking bar 2 drawn by a two-dot chain line in FIGS. 1 and 4 and is the position where the blocking bar 2 is retracted.

  The guide bar 4 is for returning the blocking bar 2 moved to the retracted position V to the operating position U. The guide bar 4 is provided on the housing 1 and extends upward so as to gradually move away from the housing 1 from the back side in the traveling direction of the vehicle 20 toward the near side, and gradually from the traffic lane. It is a rod provided so as to extend away. When the blocking bar 2 is rotated around the shaft 8 from the closed position C to the open position O when the blocking bar 2 is in the retracted position V, the guide bar 4 comes into contact with the bar holder 3 and blocks. The rod 2 is rotated from the retracted position V to the operating position U.

  The impact mitigating unit 5 is for mitigating an impact applied to the guide bar 4 when the blocking bar 2 rotates from the operation position U toward the retracted position V. In the first embodiment, the impact relaxation unit 5 is an impact absorbing material provided between the guide bar 4 and the housing 1. As a specific example, the impact relaxation unit 5 is a cylinder damper or a liquid shock absorber.

*** Explanation of operation ***
With reference to FIG. 3, the opening / closing operation | movement of the start control apparatus 10 which concerns on Embodiment 1 is demonstrated.
In the opening / closing operation, the start control device 10 rotates the bar holder 3 by the power of the drive unit 7 so that the blocking rod 2 extends substantially horizontally and does not allow the vehicle 20 to pass, and substantially vertically. The vehicle 20 is rotated in a substantially vertical direction with respect to an open position O that allows the vehicle 20 to pass.
In principle, the vehicle 20 passes through the traffic lane when the blocking bar 2 is in the open position O, and does not pass through the traffic lane when the blocking bar 2 is in another position. However, when the blocking bar 2 is at a position other than the open position O, the vehicle 20 may pass through the traffic lane. In this case, the vehicle 20 and the blocking bar 2 come into contact with each other.

With reference to FIG. 4, the retraction | saving operation | movement of the start control apparatus 10 which concerns on Embodiment 1 is demonstrated.
As described above, when the blocking bar 2 is in a position other than the open position O, the vehicle 20 passes through the traffic lane, and the retraction operation is performed when the vehicle 20 and the blocking bar 2 come into contact with each other. In the retracting operation, the bar holder 3 is bent at the movable portion 31 and the blocking rod 2 is rotated from the operating position U to the retracting position V in a substantially horizontal direction in the traveling direction X of the vehicle 20 (see FIGS. 1 and 3). . When the blocking bar 2 moves to the retracted position V, it is temporarily fixed at the retracted position V.
By performing the retreat operation, it is possible to reduce damage to the blocking bar 2 when the vehicle 20 and the blocking bar 2 come into contact with each other.

With reference to FIG. 5, the return operation of the start control apparatus 10 according to the first embodiment will be described.
As described above, when the blocking bar 2 moves to the retracted position V, the return operation is performed by remote operation or the like. In the returning operation, in the state where the blocking bar 2 is at the retracted position V, the blocking bar 2 is rotated by the power of the drive unit 7 from the closed position C toward the open position O. Then, as the bar holder 3 comes into contact with the guide bar 4 and the blocking bar 2 rotates from the closed position C toward the open position O, the blocking bar 2 gradually moves to the retracted position V. From one side to the operation position U. When the blocking bar 2 moves to the open position O, the blocking bar 2 moves to the operating position U.
The bar holder 3 is provided with a guide roller 6 at a portion in contact with the guide bar 4. When the bar holder 3 comes into contact with the guide bar 4 and the blocking bar 2 rotates, the guide roller 6 rotates and the bar holder 3 and the guide bar 4 rub against each other. Damage is prevented.
With the return operation using the guide bar 4, it is possible to return the blocking bar 2 from the retracted position V to the operating position U simply by opening and closing the blocking bar 2.

Here, not only when the blocking bar 2 is in the open position O, but also when the vehicle 20 passes through the passage lane and the vehicle 20 and the blocking bar 2 are in contact with each other while the blocking bar 2 is opening and closing. There is. If the vehicle 20 and the blocking bar 2 come into contact with each other while the blocking bar 2 is being opened and closed, and the retracting operation is performed, the bar holder 3 may collide with the guide bar 4. When the bar holder 3 collides with the guide bar 4, the bar holder 3 or the guide bar 4 may be damaged.
However, in the start control device 10 according to the first embodiment, an impact relaxation portion 5 that is an impact absorbing material is provided between the guide bar 4 and the housing 1. When the bar holder 3 collides with the guide bar 4, the impact received by the bar holder 3 and the guide bar 4 is absorbed by the impact relaxation unit 5.

*** Effects of Embodiment 1 ***
As described above, the start control device 10 according to the first embodiment includes the impact relaxation unit 5. Therefore, it is possible to reduce damage to the start control device 10 when the vehicle 20 and the blocking bar 2 come into contact with each other while the blocking bar 2 is opening and closing and the bar holder 3 collides with the guide bar 4.

*** Other configurations ***
<Modification 1>
In the first embodiment, the impact relaxation unit 5 is an impact absorbing material provided between the guide bar 4 and the housing 1. However, as a first modification, the impact relaxation unit 5 may be an impact absorbing material provided on the guide roller 6 of the bar holder 3. As a specific example, the impact relaxation part 5 is sponge and urethane.
Thereby, damage to the start control device 10 can be reduced with a simpler configuration.

  Note that both the shock absorber provided between the guide bar 4 and the housing 1 described in the first embodiment and the shock absorber provided in the guide roller 6 described in the first modification are used. Alternatively, it may be provided as the impact relaxation part 5.

<Modification 2>
Further, as a second modification, the impact relaxation unit 5 may be a moving mechanism that moves the guide bar 4 to a position where it does not contact the bar holder 3. That is, the impact relaxation unit 5 moves the guide bar 4 to a position where it does not come into contact with the bar holder 3 except during the return operation in which the blocking bar 2 is moved from the retracted position V to the operating position U.
This prevents the bar holder 3 from colliding with the guide bar 4 even if the vehicle 20 and the blocking bar 2 are in contact with each other while the blocking bar 2 is being opened and closed, thereby damaging the start control device 10. Can be reduced.

  In this case, when the return operation is executed, the guide bar 4 moves to a position where the guide bar 4 comes into contact with the bar holder 3. When the return operation is completed, the guide bar 4 moves to a position where it does not come into contact with the bar holder 3. When the guide bar 4 finishes moving to a position where it does not come into contact with the bar holder 3, the opening / closing operation is started.
