Description

Technical Field

[0001] The present disclosure relates to a starting control device capable of preventing the progress of a vehicle traveling on a road.

Background Art

[0002] As a starting control device capable of preventing the progress of a vehicle traveling on a road, for example, there is a device disclosed in Patent Document 1 below. This starting control device has a rotating shaft, a rotating mechanism for rotating the rotating shaft, a blocking bar connected to the rotating shaft, and a mechanism support portion for supporting the rotating mechanism.

[0003] The rotating shaft of this starting control device is parallel to the road. Further, the rotating shaft is inclined with respect to the vertical direction such that the proximal end of the rotating shaft is located on the downstream side (+X direction side) in the lane direction, which is the side where the vehicle travels, with respect to the proximal end of the rotating shaft. The blocking bar is connected to the rotating shaft so as to be perpendicular to the rotating shaft. Therefore, this blocking bar rotates between a closed position and an open position within a virtual plane perpendicular to the inclined rotating shaft. The blocking bar in the closed position extends in the horizontal direction and in the lane width direction. Also, the blocking bar in the open position extends in the lane direction and is inclined with respect to the horizontal plane such that the tip of this blocking bar is located above the base end of the blocking bar.

Summary of the Invention

Problems to be Solved by the Invention

[0005] According to the launch control mechanism described in Patent Document 1, a vehicle access barrier that can perform a smooth release operation with a simple and compact configuration is provided, which includes a rotating shaft that is rotatable around an inclined axis and a blocking rod that extends at a predetermined angle with respect to the inclined axis and is supported by the rotating shaft, and is configured so that as the rotating shaft rotates, the blocking rod rotates between a blocking position that blocks the passage of vehicles and a release position that allows the passage of vehicles, so that the blocking rod rotates in a conical shape.

[0006] However, this mechanism releases in the same direction as the opening direction, so there is no possibility of the retaining bar hitting the ground during release. However, if a vehicle collides with the mechanism during rotation, the direction in which the impact force is transmitted and the vector of the release movement do not coincide, which presents a problem as it could damage the retaining bar or the release mechanism.

[0007] This disclosure was made to solve the above-mentioned problems and aims to provide a launch control device that can improve safety when a vehicle collides with a barrier bar. [Means for solving the problem]

[0008] To solve the above problems, the launch control device according to the present disclosure comprises a rotating shaft, a rotating mechanism that rotates the rotating shaft about the central axis of the rotating shaft, a blocking rod connected to the rotating shaft, a rotating part installed on the roadside of the lane and supporting the rotating mechanism, and a main body that rotatably supports the rotating part, wherein the rotating shaft extends in the horizontal direction, the tip of the rotating shaft is located downstream in the lane direction relative to the base of the rotating shaft, and the rotating shaft is supported by the rotating part via the rotating mechanism such that the central axis of the rotating shaft is inclined with respect to the lane direction, and the blocking rod moves in conjunction with the rotation of the rotating shaft, the central axis A rotating mechanism is connected to the tip of the rotating shaft, inclined with respect to the central axis, so as to be rotatable along a virtual conical surface centered on a line, and the rotating mechanism rotates the rotating shaft so as to achieve a closed position in which the blocking bar extends horizontally and in the lane width direction, and an open position in which the blocking bar extends in a direction in which the horizontal component is greater than the vertical component and the component in the lane direction is greater than the component in the lane width direction. The rotating part rotates in response to a predetermined external force applied to the blocking bar, and returns from the position after rotation due to the external force to a predetermined initial position due to the reaction force received by the blocking bar as the rotating mechanism rotates. [Effects of the Invention]

[Modes for carrying out the invention]

[0011] Hereinafter, the starting control device according to the embodiment of this disclosure will be described with reference to Figures 1 to 10. Figure 1 is a perspective view of the toll booth in the embodiment according to this disclosure. Figures 2 to 7 are perspective views of the starting control device in the embodiment according to this disclosure. Figures 7 to 9 are schematic overall plan views showing the starting control device in the embodiment according to this disclosure. Figure 10 is a view taken along arrow V in Figure 7. In each figure, the same or corresponding components are used with the same reference numerals, and explanations are omitted as appropriate.

[0012] <Toll booth configuration> As shown in Figure 1, toll booths on toll roads have lane R, which is a driving lane that leads from the toll road to the general road. Here, the direction in which lane R extends is called the lane direction (±X direction), the direction in which vehicle C is traveling is called the downstream side of the lane direction (+X direction side), and the opposite side of the downstream side of the lane direction is called the upstream side of the lane direction (-X direction side). Furthermore, the width direction of lane R is called the lane width direction (±Y direction), the left side when facing the downstream side of the lane direction (+X direction side) is called the left side of the lane width direction (+Y direction side), and the right side when facing the downstream side of the lane direction (+X direction side) is called the right side of the lane width direction (-Y direction side). In addition, the direction perpendicular to the road surface of lane R is called the up and down direction (±Z direction), the upper side is called the up and down upper side (+Z direction side), and the lower side is called the up and down lower side (-Z direction side).

[0013] The lane R shown in FIG. 1 is, as an example, a lane where both toll collection by an Electronic Toll Collection System (ETC (registered trademark); hereinafter also simply referred to as "ETC" in the following description) and toll collection by the automatic toll collector 1 are possible.

[0014] On both roadside sides in the lane width direction of the lane R, islands I are provided respectively. On the island I, an automatic toll collector 1, vehicle detectors 2 and 4, an antenna 3, a start control device 10, and a control device 5 are installed.

[0015] The automatic toll collector 1 is provided on one of the islands I on both sides of the lane R. This automatic toll collector 1 is a device that accepts payment of tolls from the users boarding the vehicle C when the vehicle C does not correspond to toll collection by ETC.

[0016] The antenna 3 performs wireless communication with the in-vehicle device of the vehicle C that has entered the lane R and performs toll collection processing by ETC. When the entering vehicle C corresponds to toll collection by ETC (that is, when a dedicated in-vehicle device is installed), during travel on the lane R, toll collection processing by ETC via the antenna 3 is performed.

[0017] The vehicle detector 2 has a light emitter 2a and a light receiver 2b that face each other in the lane width direction (±Y direction). The light emitter 2a is provided on one of the islands I on both sides of the lane R, and the light receiver 2b is provided on the other island I. With such a configuration, the vehicle detector 2 can detect the presence or absence of the vehicle C between the light emitter 2a and the light receiver 2b. The vehicle detector 2 is arranged on the upstream side (-X direction side) in the lane direction from the automatic toll collector 1 and the antenna 3. The automatic toll collector 1 and the antenna 3 start operations for various toll collections triggered by the detection of the entry of the vehicle C into the lane R by the vehicle detector 2.

[0018] Similarly, the vehicle detector 4 has a projector 4a and a light receiver 4b that face each other in the lane width direction (±Y direction). The projector 4a is provided on one of the islands I on both sides of the lane R, and the light receiver 4b is provided on the other island I. With such a configuration, the vehicle detector 4 can detect the presence or absence of the vehicle C between the projector 4a and the light receiver 4b. The vehicle detector 4 is arranged on the downstream side in the lane direction (+X direction side) of the start control device 10 described later. The start control device 10 is controlled to perform a closing operation triggered by the detection of the vehicle C exiting the lane R by the vehicle detector 4.

[0019] The start control device 10 is provided on each of the islands I on both sides of the lane R. The start control device 10 is arranged on the downstream side in the lane direction (+X direction side) of the toll collector 1. The start control device 10 has a stop bar 11 for controlling the temporary stop and start of the vehicle C traveling on the lane R.

[0020] When the control device 5 determines that the regular toll has been paid as a result of the wireless communication between the in-vehicle device of the vehicle C and the antenna 3 or as a result of the toll collection by the toll collector 1, the control device 5 instructs the start control device 10 to move the stop bar 11 to the open position in order to allow the vehicle C to exit the lane R. Also, when it is determined that the regular toll has not been paid, the control device 5 instructs the start control device 10 to move the stop bar 11 to the closed position so that the vehicle C does not exit the lane R.

[0021] Note that the above-described mode of the toll booth is an example and is not limited to this mode. For example, the lane R of the toll booth may be a lane where no toll collector 1 is installed and only vehicles compatible with ETC can travel, or no antenna 3 is installed and all vehicles pay tolls through the toll collector 1. Also, a manned booth where a toll collector waits may be installed instead of the toll collector orte 1, and the toll collector may receive the payment of the toll.

[0022] <Configuration and Operation of the Start Control Device> The configuration and operation of the launch control unit in this embodiment will be described with reference to Figures 2 to 10.

[0023] As shown in Figure 2, the launch control unit 10 in this embodiment comprises a blocking rod 11, a rotating part 17, and a main body part 18. Furthermore, the rotating part 17 and the main body part 18 are distributed together, or the rotating part 17 alone comprises the rotating mechanism 63 in this embodiment. The rotating mechanism 63 is a mechanism that rotates the rotating shaft 15 about its central axis Ac. The rotating mechanism 63 includes at least the rotating shaft 15. In addition to the rotating shaft 15, the rotating mechanism 63 may also include bevel gears 57 and 56, an electric motor 51, a torque limiter 53, a pivot shaft 54, and the like.

[0024] Figure 2 shows the case where the blocking rod 11 is in the closed position. The rotating part 17 comprises a rotating shaft 15, a bevel gear 57, and a bevel gear 56. The main body part 18 comprises an electric motor 51, a torque limiter 53, a pivot shaft 54, a ball plunger 61, and a burst stopper 62.

[0025] The rotating part 17 is rotatably supported relative to the main body 18 using bearings 55 or the like. The rotating part 17 rotates about the central axis Ar of the pivot shaft 54, which is perpendicular to the horizontal direction. The rotating part 17 rotates in response to an external force of a predetermined magnitude or greater applied to the retaining rod 11, for example. The rotating part 17 also returns from the position after rotation due to the external force to a predetermined initial position due to the reaction force that the retaining rod 11 receives from the burst stopper 62 as the rotating mechanism 63 rotates. The initial position is, for example, the position of the rotating part 17 relative to the main body 18 in the state shown in Figure 2. This initial position is positioned by a ball plunger 61. For the rotating part 17 to start rotating from the initial position, an external force sufficient to overcome the restraining force of the ball plunger 61 is required. In this embodiment, the state in which the rotating part 17 is rotated to move the retaining rod 11 to, for example, the same position as the open position is called the release state. Although Figure 2 and other figures show an example in which the wall surface of the housing of the rotating part 17 is restrained by the ball plunger 61, a configuration in which a recess is provided on the bottom surface of the rotating part 17 and then positioning is performed by the ball plunger 61 may also be used.

[0026] The drive shaft 52 of the electric motor 51 is coaxially connected to the pivot shaft 54 ​​via a torque limiter 53. The torque limiter 53 disconnects the drive shaft 52 and the pivot shaft 54 ​​when a torque exceeding a predetermined magnitude is applied between them, and reconnects them when the torque falls below the predetermined magnitude. Therefore, for example, if a large external force is applied to the stopper rod 11, it prevents excessive external force from being applied to the electric motor 51. The ball plunger 61 and the torque limiter 53 constitute the overload release mechanism 59, each having the function of releasing external forces exceeding a predetermined value applied to the rotating mechanism 63 in parallel. Furthermore, when the overload release mechanism 59 includes the ball plunger 61, the overload release mechanism 59 has the function of positioning the initial position of the rotating part 17. Furthermore, when the overload release mechanism 59 includes the torque limiter 53, it has the function of disconnecting the drive shaft 52 and the pivot shaft 54 ​​in the event of an overload.

[0027] The driving force generated by the electric motor 51 is applied to the rotating shaft 15 via the drive shaft 52, torque limiter 53, pivot shaft 54, bevel gears 56 and 57. In this embodiment, the rotating mechanism 63 rotates the rotating shaft 15 in accordance with the rotation of the drive shaft 52 of the electric motor 51 installed in the main body 18. Furthermore, the drive shaft 52 of the electric motor 51 is coaxial with the pivot shaft 54.

[0028] The burst stopper 62 is, for example, a rod-shaped member that restricts the movement of the stopping rod 11 so that it does not rotate beyond a predetermined open position. When the stopping rod 11 is in contact with the burst stopper 62 and the rotation axis 15 rotates further in the direction that opens the stopping rod 11, the stopping rod 11 receives a reaction force from the burst stopper 62.

[0029] The rotation mechanism 63 can rotate the rotation shaft 15 about its central axis Ac. The main body 18 rotatably supports the rotating part 17. This main body 18 is positioned on an island I provided on the roadside of the lane R. The main body 18 supports the rotation shaft 15 via the rotating part 17 such that the rotation shaft 15 extends horizontally (parallel to the XY plane), and the tip 15t of the rotation shaft 15 is located downstream in the lane direction (+X direction) relative to the base 15b of the rotation shaft 15, so that the central axis Ac of the rotation shaft 15 is inclined with respect to the lane direction (±X direction). In this embodiment, the axial inclination angle α, which is the inferior angle among the conjugate angles of the central axis Ac with respect to the lane direction (±X direction), is 45° (see Figure 7).

[0030] The blocking rod 11 is connected to the tip 15t of the rotating shaft 15, tilted with respect to the central axis Ac, so that it can rotate along a virtual conical surface centered on the central axis Ac as the rotating shaft 15 rotates. In this embodiment, the rod inclination angle β, which is the inferior angle among the conjugate angles of the blocking rod 11 with respect to the central axis Ac, is 45°. In addition, although it was explained above that the blocking rod 11 is connected to the "tip portion 15t" of the rotating shaft 15, the "tip portion" here does not necessarily mean only the tip portion of the rotating shaft 15. In other words, the expression "The blocking rod 11 is connected to the tip portion 15t of the rotating shaft 15" is also to include configurations in which a part of the rotating shaft 15 extends further beyond the "tip portion 15t" to which the blocking rod 11 is connected, or configurations in which other attachments exist.

[0031] As shown in Figure 7, the rotating part 17 can rotate the rotating shaft 15 to achieve a closed position Sc in which the blocking bar 11 extends horizontally and in the lane width direction (±Y direction), and an open position So in which the blocking bar 11 extends horizontally and in the lane direction (±X direction). The blocking bar 11 in the open position So is symmetrical with respect to the blocking bar 11 in the closed position Sc, with respect to the central axis Ac of the rotating shaft 15 which extends horizontally. In this embodiment, the blocking bar 11 in the closed position Sc has no components in the vertical direction (±Z direction) and the lane direction (±X direction), and extends horizontally and in the lane width direction (±Y direction). Similarly, the blocking bar 11 in the open position So has no components in the vertical direction (±Z direction) and the lane width direction (±Y direction), and extends horizontally and in the lane direction (±X direction). Here, the expression "no component in the XX direction" includes not only the complete absence of a component in the XX direction, but also cases where a small amount of a component in the XX direction is present due to, for example, the deflection of the blocking rod 11 or manufacturing tolerances.

[0032] Next, the operation of the launch controller 10 described above will be explained with reference to Figures 2 to 10. Figure 2 shows the launch controller 10 with the stopper rod 11 in the closed position. Figure 3 shows an example of the opening and closing operation of the stopper rod 11. Figure 4 shows the launch controller 10 with the stopper rod 11 in the open position. Figure 5 shows the launch controller 10 with the stopper rod 11 in the released position. Figure 6 shows the launch controller 10 with the stopper rod 11 in the return operation. Figure 7 shows the launch controller 10 with the stopper rod 11 in the returned open position (open state). Figure 7 shows the closed position Sc, the open position So, and an example of the opening and closing operation of the stopper rod 11. Figure 8 shows the case when the rotating part 17 rotates and the stopper rod 11 is in the release position Sr. Figure 9 shows the state when the rotating part 17 has returned to the initial position. Figure 10 shows an example of the opening and closing operation of the stopper rod 11.

[0033] The opening operation of the blocking rod 11 is performed, for example, from the closed state shown in Figure 2, by driving the electric motor 51, causing the blocking rod 11 to trace a conical trajectory as shown in Figures 3, 7, and 10, and transition to the open state shown in Figure 4. The closing operation is in the reverse direction of Figure 4 → Figure 3 → Figure 2.

[0034] Furthermore, the bar release and return operation from the released state are as follows. For example, if a vehicle collides with the bar in the closed state as shown in Figure 2, the rotating part 17 rotates as shown in Figure 5, releasing the stopping bar 11 until it hits, for example, the bar stopper 62. Figure 8 shows an example when the stopping bar 11 is in the released state. The torque when the bar is released can be adjusted by the ball plunger 61 and the torque limiter 53.

[0035] The return operation can be performed by driving the blocking rod 11 in the same way as the opening operation. When the blocking rod 11 is opened in the released state shown in Figure 5, the reaction force from the burst stopper 62 to the blocking rod 11 causes the rotating part 17 to rotate (rotate), returning it to its initial position. In other words, in this embodiment, both the opening and closing of the blocking rod 11 and the return of the rotating part 17 can be performed with a single electric motor 51. In this case, the opening and closing motor also serves as the return motor.

[0036] Figure 6 shows an example of the return operation. The completed return state of the rotating part 17 is the same as the open state shown in Figure 4. Figure 9 shows an example of the completed return state. After that, the closed state shown in Figure 2 can be returned by performing the normal closing operation.

[0037] As described above, the blocking bar 11 in the closed position Sc extends horizontally and in the lane width direction (±Y direction). When the rotating part 17 positions the blocking bar 11 in the closed position Sc to the open position So, it rotates the rotation axis 15 so that the blocking bar 11 in the closed position Sc begins to rotate upward in the vertical direction (+Z direction). As the rotation axis 15 rotates, the blocking bar 11 rotates along a virtual conical surface centered on the central axis Ac to reach the open position So. As mentioned above, the blocking bar 11 in this open position So extends horizontally and in the lane direction (±X direction).

[0038] When the rotating part 17 moves the blocking rod 11 from the open position So to the closed position Sc, it also rotates the rotation axis 15 so that the blocking rod 11 in the open position So begins to rotate upward in the vertical direction (+Z direction). Therefore, the direction of rotation of the rotation axis 15 when moving the blocking rod 11 from the open position So to the closed position Sc is the opposite direction to the direction of rotation of the rotation axis 15 when moving the blocking rod 11 from the closed position Sc to the open position So. When the rotation axis 15 rotates, the blocking rod 11 rotates along a virtual conical surface centered on the central axis Ac, and returns to the closed position Sc.

[0039] Furthermore, for example, if a vehicle C traveling in lane R hits the stopper bar 11 in the closed position Sc, and a load exceeding a predetermined amount is applied to the stopper bar 11 horizontally and downstream in the lane direction (+X direction), the rotating part 17 rotates. The rotating part 17 then rotates until the stopper bar 11 hits the burst stopper 62, and the stopper bar 11 moves to the release position Sr. Even if the stopper bar 11 does not hit the burst stopper 62, the stopper bar 11 can be moved until it hits the burst stopper 62 by performing a return operation (opening operation), and the above return operation can be performed. Furthermore, to prevent the stopping bar 11 from bouncing back towards the lane R side and damaging, for example, vehicle C, after it hits the burst stopper 62, a rebound prevention mechanism, such as a holding mechanism, may be provided on the burst stopper 62 to prevent the stopping bar 11 from bouncing back. Also, to prevent the stopping bar 11 from remaining in the lane R when released, a mechanism may be provided on the rotation mechanism 63 that rotates the stopping bar 11 by means of a spring or the like until it hits the burst stopper 62.

[0040] As described above, in this embodiment, the barrier bar 11 rotates along a virtual conical surface centered on a horizontally extending central axis Ac as the rotation of the rotation axis 15 occurs. Furthermore, the barrier bar 11 in the closed position Sc extends horizontally and in the lane width direction (±Y direction). Therefore, in this embodiment, as shown in Figure 5, when the barrier bar 11 in the closed position Sc is displaced to the open position So, the barrier bar 11 in the closed position Sc is first displaced in the vertical direction (±Z direction), and then the amount of displacement in the vertical direction (±Z direction) gradually decreases, while the amount of displacement in the lane width direction (±Y direction) and the lane direction (±X direction) increases. Thus, in this embodiment, the visibility of the opening start operation of the barrier bar 11 in the closed position Sc is increased for the driver of vehicle C, making it easier for the driver to recognize that passage is permitted.

[0041] Furthermore, in this embodiment, the blocking bar 11 in the open position So extends in a direction where the horizontal component is larger than the vertical component (±Z direction), and the lane-direction (±X direction) component is larger than the lane-width direction (±Y direction). As a result, the driver of vehicle C has reduced visibility of the blocking bar 11 in the open position So. Therefore, the driver can pass the launch control unit 10 without being concerned about the presence of the blocking bar 11.

[0042] In particular, in this embodiment, since the blocking bar 11 in the open position So extends in a direction that does not have a vertical (±Z direction) component (i.e., extends horizontally), the visibility of the blocking bar 11 in the open position So to the driver of vehicle C can be further reduced.

[0043] Furthermore, in this embodiment, since the blocking bar 11 in the open position So extends in a direction that does not have a component in the lane width direction (±Y direction), it is possible to avoid the tip portion 11t of the blocking bar 11 in the open position So protruding into the lane R.

[0044] As described above, according to this embodiment, the retaining bar 11 is released by rotating the rotating part 17 when it is released. For example, even if a bar release (collision) occurs when the opening operation of the retaining bar 11 is only partially completed, it is possible to prevent the retaining bar 11 from hitting the ground.

[0045] Furthermore, in this embodiment, by performing the opening operation, the reaction force received by the stopping rod 11 from the burst stopper 62 is used to return the position of the rotating part 17 to its initial position, thus eliminating the need for a motor for return. In addition, by making the rotating part 17 rotate around the central axis Ar of the pivot shaft 54 ​​which is perpendicular to the horizontal direction, the stopping rod 11 can be moved horizontally during release to the release position.

[0046] Furthermore, by positioning the initial position of the rotating part 17 with the ball plunger 61, it is possible to adjust the torque at the time of release as well as position the part.

[0047] Furthermore, when the rotating mechanism 63 rotates the rotating shaft 15 in conjunction with the rotation of the drive shaft 52 of the electric motor 51 installed in the main body 18, the drive shaft 52 of the electric motor 51 is coaxial with the rotating shaft 54, which makes it easy to simplify the configuration for rotating the rotating part 17.

[0048] Furthermore, since the drive shaft 52 and the rotating shaft 54 ​​are connected via a torque limiter 53, it is possible to prevent overloading the electric motor 51 and also to adjust the release torque using the torque limiter 53.

[0049] Furthermore, in this embodiment, when the barrier bar 11 comes into contact with the vehicle C, the barrier bar 11 swings within the horizontal plane. Therefore, the horizontal load on the barrier bar 11 in the direction of the lane and downstream (+X direction) when it comes into contact with the vehicle can be effectively relieved. Thus, in this embodiment, the load on the barrier bar 11 and the parts supporting the barrier bar 11 when it comes into contact with the vehicle can be suppressed, and damage to them can be reduced.

[0050] Furthermore, in this embodiment, since the release position Sr is the same as the open position So, the control for moving the blocking rod 11 from the release position Sr to the closed position Sc and the control for moving the blocking rod 11 from the open position So to the closed position Sc are the same, making it easier to control the rotating part 17.

[0051] Although embodiments of this disclosure have been described in detail above, this disclosure is not limited to the embodiments described above. Various additions, modifications, substitutions, and partial deletions are possible, provided that they do not depart from the conceptual idea and spirit of the present invention derived from the claims and their equivalents.

[0052] For example, in the above embodiment, the opening / closing operation and the return operation are performed by a single electric motor 51, but they may be performed by separate electric motors. Also, the plunger may be a plunger other than a ball plunger.

[0053] <Note> The launch control device in the above embodiments can be understood, for example, as follows.

[0054] (1) The launch control unit 10 in the first embodiment is Rotation axis 15 and A rotation mechanism 63 that rotates the rotation shaft 15 about the central axis Ac of the rotation shaft 15, A blocking rod 11 connected to the aforementioned rotating shaft 15, A rotating part 17 is installed on the roadside of lane R and supports the rotating mechanism 63, A main body portion 18 that rotatably supports the rotating portion 17, Equipped with, The rotating shaft 15 extends horizontally, and its tip portion 15t is located downstream in the lane direction relative to its base portion 15b, and the rotating shaft 15 is supported by the rotating part 17 via the rotating mechanism 63 such that the central axis Ac of the rotating shaft 15 is inclined with respect to the lane direction. The blocking rod 11 is connected to the tip portion 15t of the rotating shaft 15, inclined with respect to the central axis Ac, so that it can rotate along a virtual conical surface centered on the central axis Ac as the rotating shaft 15 rotates. The rotation mechanism 63 rotates the rotation shaft 15 to enable a closed position Scr in which the blocking bar 11 extends horizontally and in the lane width direction, and an open position So in which the blocking bar 11 extends in a direction in which the horizontal component is greater than the vertical component and the component in the lane direction is greater than the component in the lane width direction. The rotating part 17 rotates in response to a predetermined external force applied to the retaining rod 11, and returns to a predetermined initial position from the position after rotation due to the external force by the reaction force received by the retaining rod 11 as the rotating mechanism 63 rotates.

[0055] According to this embodiment and the following embodiments, it is possible to provide a launch control device that can improve safety when a vehicle collides with a blocking bar 11.

[0056] (2) The launch control device in the second embodiment is: In the launch control device 10 according to the first embodiment, the rotating part 17 rotates about the central axis Ar of the pivot shaft 54 ​​which is perpendicular to the horizontal direction. According to this embodiment, the stopper rod 11 can be moved horizontally to the release position Sr.

[0057] (3) The launch control device in the third embodiment is: In the launch control unit 10 according to the first or second embodiment, the initial position is determined by the overload release mechanism 59. According to this embodiment, the overload release mechanism 59 can adjust both the positioning and the release torque.

[0058] (4) The launch control device in the fourth embodiment is: The rotating mechanism rotates the rotating shaft in conjunction with the rotation of the drive shaft of the electric motor installed in the main body, and the drive shaft of the electric motor is coaxial with the rotating shaft. This configuration simplifies the structure.
