Description

[Technical field]

[0001] The present disclosure relates to a launch control device capable of arresting the progress of a vehicle traveling on a road. [Background technology]

[0002] An example of a launch control device capable of blocking the progress of a vehicle traveling on a road is the device disclosed in the following Patent Document 1. This launch control device has a rotating shaft, a rotating mechanism that rotates the rotating shaft, a blocking rod connected to the rotating shaft, and a mechanism support part that supports the rotating mechanism.

[0003] The rotation axis of this starting controller is parallel to the road. Furthermore, the rotation axis is inclined in the vertical direction so that the base end of the rotation axis is located downstream (+X direction side) in the lane direction, which is the side in which the vehicle travels, relative to the base end of the rotation axis. The blocking bar is connected to the rotation axis so as to be perpendicular to the rotation axis. Therefore, the blocking bar rotates between a closed position and an open position in an imaginary plane perpendicular to the inclined rotation axis. In the closed position, the blocking bar extends horizontally and in the lane width direction. In addition, in the open position, the blocking bar extends in the lane direction and is inclined with respect to the horizontal plane so that the tip of the blocking bar is located above the base end of the blocking bar.

[0004] [Patent Document 1] Patent No. 5675180 Summary of the Invention [Problem to be solved by the invention]

[0005] According to the starting control mechanism described in Patent Document 1, a vehicle passage barrier capable of performing a smooth release operation with a simple and compact configuration is provided with a rotating shaft arranged to be rotatable around an inclined axis, and a blocking bar extending at a predetermined angle to the inclined axis and supported by the rotating shaft, and as the rotating shaft rotates, the blocking bar is configured to rotate between a blocking position which blocks the vehicle from passing and a release position which allows the vehicle to proceed, so that the blocking bar rotates to describe a conical surface.

[0006] However, with this mechanism, the release is in the same direction as the opening direction, so there is no possibility of the blocking bar hitting the ground when released. However, there was an issue in that if the vehicle collides during the rotation, the direction of the impact force and the vector of the release movement do not match, which could cause damage to the blocking bar and release mechanism.

[0007] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a launch control device that can improve safety in the event of a vehicle colliding with a blocking bar. [Means for solving the problem]

[0008] In order to solve the above problems, a starting control device according to the present disclosure includes a rotating shaft, a rotating mechanism that rotates the rotating shaft around a central axis of the rotating shaft, a blocking bar connected to the rotating shaft, a rotating unit that is installed on the roadside of a lane and supports the rotating mechanism, and a main body that rotatably supports the rotating unit, wherein the rotating shaft extends in a horizontal direction, a tip end of the rotating shaft is located downstream in the lane direction relative to a base end of the rotating shaft, and the central axis of the rotating shaft is inclined with respect to the lane direction. The blocking bar moves along the central axis as the rotating shaft rotates. The rotating mechanism is connected to the tip of the rotating shaft, inclined relative to the central axis, and rotatable along a virtual conical surface centered on a line, and rotates the rotating shaft so as to realize 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 up-down component and the lane direction component is greater than the lane width direction component, and the rotating part rotates in response to a predetermined external force applied to the blocking bar, and returns to a predetermined initial position from the position after rotation due to the external force due to the reaction force that the blocking bar receives as the rotating mechanism rotates. Effect of the Invention

[0009] The launch control device of the present disclosure can improve safety in the event of a vehicle colliding with the blocking bar. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] A starting control device according to an embodiment of the present disclosure will be described below with reference to Figs. 1 to 10. Fig. 1 is a perspective view of a toll booth in an embodiment of the present disclosure. Figs. 2 to 7 are perspective views of a starting control device in an embodiment of the present disclosure. Figs. 7 to 9 are overall plan views typically showing a starting control device in an embodiment of the present disclosure. Fig. 10 is a view seen from the V arrow in Fig. 7. Note that the same reference numerals are used for the same or corresponding configurations in each drawing, and descriptions thereof will be omitted as appropriate.

[0012] <Toll booth type> As shown in FIG. 1, at the exit toll gate of the toll road, a lane R is installed, which is a driving lane that leads from the toll road to a general road. Here, the direction in which the lane R extends is called the lane direction (±X direction), the direction in which the vehicle C travels is also called the downstream side in the lane direction (+X direction side), and the opposite side of the downstream side in the lane direction is also called the upstream side in the lane direction (-X direction side). In addition, the width direction of the lane R is called the lane width direction (±Y direction), the left side toward the downstream side in the lane direction (+X direction side) is also called the left side in the lane width direction (+Y direction side), and the right side toward the downstream side in the lane direction (+X direction side) is also called the right side in the lane width direction (-Y direction side). Furthermore, the direction perpendicular to the road surface of the lane R is called the up-down direction (±Z direction), the upper side is also called the up-down direction upper side (+Z direction side), and the lower side is also called the up-down direction lower side (-Z direction side).

[0013] As an example, lane R shown in Figure 1 is a lane where toll collection is possible both via an electronic toll collection system (ETC (registered trademark); in the following description, this will also be referred to simply as "ETC") and via an automatic toll collection machine 1.

[0014] An island I is provided on each side of the road in the width direction of the lane R. An automatic toll collection machine 1, vehicle detectors 2 and 4, an antenna 3, a departure control device 10, and a control device 5 are installed on the island I.

[0015] The automatic toll collection machine 1 is installed on one of the islands I on both sides of the lane R. This automatic toll collection machine 1 is a device that accepts toll payments from users of vehicles C when the vehicles C do not support toll collection by ETC.

[0016] The antenna 3 performs wireless communication with the on-board unit of the vehicle C that has entered lane R, and performs toll collection processing by ETC. If the vehicle C that has entered is compatible with toll collection by ETC (i.e., if a dedicated on-board unit is installed), toll collection processing by ETC is performed via the antenna 3 while the vehicle is traveling on lane R.

[0017] The vehicle detector 2 has a projector 2a and a receiver 2b that face each other in the lane width direction (±Y direction). The projector 2a is provided on one of the islands I on both sides of the lane R, and the receiver 2b is provided on the other island I. With this configuration, the vehicle detector 2 can detect the presence or absence of a vehicle C between the projector 2a and the receiver 2b. The vehicle detector 2 is disposed upstream in the lane direction (-X direction) of the automatic toll collection machine 1 and the antenna 3. The automatic toll collection machine 1 and the antenna 3 start operations for collecting various tolls when the vehicle detector 2 detects that a vehicle C has entered the lane R.

[0018] Similarly, the vehicle detector 4 has a projector 4a and a 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 receiver 4b is provided on the other island I. With this configuration, the vehicle detector 4 can detect the presence or absence of a vehicle C between the projector 4a and the receiver 4b. The vehicle detector 4 is disposed downstream in the lane direction (+X direction side) of the departure controller 10, which will be described later. The departure controller 10 is controlled to perform a closing operation when the vehicle detector 4 detects that the vehicle C has left the lane R, as a trigger.

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

[0020] When the control device 5 determines, as a result of wireless communication between the vehicle-mounted device of the vehicle C and the antenna 3, or as a result of toll collection by the toll collection machine 1, that the correct toll has been paid, it instructs the starting control device 10 to set the blocking bar 11 to the open position so as to allow the vehicle C to exit the lane R. When the control device 5 determines that the correct toll has not been paid, it instructs the starting control device 10 to set the blocking bar 11 to the closed position so as to prevent the vehicle C from exiting the lane R.

[0021] The above-mentioned toll gate configuration is merely an example, and the present invention is not limited to this configuration. For example, the lane R of the toll gate may not be equipped with an automatic toll collection machine 1, and only vehicles compatible with ETC may be allowed to travel on the lane, or the antenna 3 may not be installed, and all vehicles may pay the toll through the automatic toll collection machine 1. Also, instead of the automatic toll collection machine 1, a manned booth where a toll collector waits may be installed, and the toll collector may accept the payment of the toll.

[0022] <Configuration and operation of the launch control device> The configuration and operation of the starting control device in this embodiment will be described with reference to FIGS.

[0023] As shown in Fig. 2, the launch control device 10 in this embodiment includes the blocking bar 11, a rotating unit 17, and a main body unit 18. In addition, the rotating unit 17 is provided with a rotating mechanism 63 in this embodiment, either distributed between the rotating unit 17 and the main body unit 18 or in the rotating unit 17. The rotating mechanism 63 is a mechanism for rotating the rotating shaft 15 around the central axis Ac of the rotating shaft 15. The rotating mechanism 63 includes at least the rotating shaft 15. In addition, the rotating mechanism 63 may include bevel gears 57 and 56, an electric motor 51, a torque limiter 53, a rotating shaft 54, and the like, in addition to the rotating shaft 15.

[0024] 2 shows the blocking rod 11 in a closed state. The rotating portion 17 includes a rotating shaft 15, a bevel gear 57, and a bevel gear 56. The main body portion 18 includes an electric motor 51, a torque limiter 53, a rotating shaft 54, a ball plunger 61, and a burst stopper 62.

[0025] The rotating part 17 is supported rotatably with respect to the main body part 18 by using a bearing 55 or the like. The rotating part 17 rotates around the central axis line Ar of the rotation shaft 54 ​​perpendicular to the horizontal direction. The rotating part 17 rotates, for example, in response to an external force of a predetermined magnitude or more applied to the blocking bar 11. In addition, the rotating part 17 returns to a predetermined initial position from a position after rotation due to an external force by the reaction force that the blocking bar 11 receives from the burst stopper 62 with the rotation of the rotation mechanism 63. The initial position is, for example, the position of the rotating part 17 with respect to the main body part 18 in the state shown in FIG. 2. This initial position is positioned by the ball plunger 61. In order 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, a state in which the rotating part 17 is rotated to move the blocking bar 11 to, for example, the same position as the open position, is called a release state. In addition, Figure 2 etc. shows an example in which ball plunger 61 is used to restrain the wall surface of the housing of rotating part 17, but it is also possible to configure it so that, for example, a recess is provided on the bottom surface of rotating part 17 and positioning is performed by ball plunger 61.

[0026] The drive shaft 52 of the electric motor 51 is coaxially connected to the rotating shaft 54 ​​via a torque limiter 53. The torque limiter 53 separates the drive shaft 52 from the rotating shaft 54 ​​when a torque of a predetermined magnitude or greater is applied between the drive shaft 52 and the rotating shaft 54, and connects the drive shaft 52 to the rotating shaft 54 ​​when the torque falls below the predetermined magnitude. Therefore, for example, when a large external force is applied to the blocking rod 11, the application of an excessive external force to the electric motor 51 is prevented. The ball plunger 61 and the torque limiter 53 constitute an overload release mechanism 59 as components that function in parallel to release an external force equal to or greater than a predetermined value that is applied to the rotation mechanism 63. When the overload release mechanism 59 includes the ball plunger 61, the overload release mechanism 59 has a function of determining the initial position of the rotating part 17. When the overload release mechanism 59 includes the torque limiter 53, the overload release mechanism 59 has a function of separating the drive shaft 52 and the rotating 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, the torque limiter 53, the rotating shaft 54, and the bevel gears 56 and 57. In this embodiment, the rotation 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. In addition, the drive shaft 52 of the electric motor 51 is coaxial with the rotating shaft 54.

[0028] The burst stopper 62 is, for example, a bar-shaped member that limits the movement of the blocking bar 11 so that the blocking bar 11 does not rotate beyond a predetermined open position. When the rotating shaft 15 rotates further in the direction in which the blocking bar 11 opens while the blocking bar 11 is in contact with the burst stopper 62, the blocking bar 11 receives a reaction force from the burst stopper 62.

[0029] The rotation mechanism 63 can rotate the rotating shaft 15 around the central axis Ac of the rotating shaft 15. The main body 18 rotatably supports the rotating part 17. The main body 18 is disposed on an island I provided on the road side of the lane R. The main body 18 supports the rotating shaft 15 via the rotating part 17 so that the rotating shaft 15 extends in a horizontal direction (a direction parallel to the XY plane), the tip end 15t of the rotating shaft 15 is located downstream in the lane direction (+X direction) with respect to the base end 15b of the rotating shaft 15, and the central axis Ac of the rotating shaft 15 is inclined with respect to the lane direction (±X direction). In this embodiment, the axial inclination angle α, which is the minor angle of the conjugate angle of the central axis Ac with respect to the lane direction (±X direction), is 45° (see FIG. 7).

[0030] The blocking rod 11 is connected to the tip 15t of the rotating shaft 15 at an inclination with respect to the central axis Ac so as to be rotatable 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 minor angle among the conjugate angles of the blocking rod 11 with respect to the central axis Ac, is 45°. In the above, it has been explained that the blocking rod 11 is connected to the "tip 15t" of the rotating shaft 15, but the "tip" 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 15t of the rotating shaft 15" also includes a state in which a part of the rotating shaft 15 extends beyond the "tip 15t" to which the blocking rod 11 is connected, or a state in which other accessories exist.

[0031] As shown in FIG. 7, the rotating part 17 can rotate the rotating shaft 15 so as to realize 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 to the blocking bar 11 in the closed position Sc with respect to the central axis Ac of the rotating shaft 15 extending horizontally. Note that the blocking bar 11 in the closed position Sc in this embodiment does not have a component in the up-down direction (±Z direction) or the lane direction (±X direction), and extends horizontally and in the lane width direction (±Y direction). Also, the blocking bar 11 in the open position So in this embodiment does not have a component in the up-down direction (±Z direction) or 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" does not only mean that there is no component in the XX direction at all, but also includes cases where a small component in the XX direction is included due to, for example, deflection of the blocking rod 11 or manufacturing errors.

[0032] Next, the operation of the launch controller 10 described above will be described with reference to Figs. 2 to 10. Fig. 2 shows the launch controller 10 with the blocking bar 11 in a closed state. Fig. 3 shows an example of the opening and closing operation of the blocking bar 11. Fig. 4 shows the launch controller 10 with the blocking bar 11 in an open state. Fig. 5 shows the launch controller 10 with the blocking bar 11 in a released state. Fig. 6 shows the launch controller 10 with the blocking bar 11 in a return operation. Fig. 7 shows the launch controller 10 with the blocking bar 11 in a return completion open state (open state). Fig. 7 shows the closed position Sc, the open position So, and an example of the opening and closing operation of the blocking bar 11. Fig. 8 shows a case where the rotating part 17 rotates and the blocking bar 11 is located at the release position Sr. Fig. 9 shows a state where the rotating part 17 has returned to its initial position. Fig. 10 shows an example of the opening and closing operation of the blocking bar 11.

[0033] In the opening operation of the blocking bar 11, for example, by driving the electric motor 51 from the closed state shown in Fig. 2, the blocking bar 11 describes a conical orbit as shown in Fig. 3, Fig. 7 and Fig. 10, and transitions to the open state shown in Fig. 4. Also, the closing operation is Fig. 4 → the reverse direction of Fig. 3 → Fig. 2.

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

[0035] The return operation can be performed by driving the blocking bar 11 in the same manner as the opening operation. When the opening operation is performed on the blocking bar 11 in the released state shown in Fig. 5, the reaction force from the burst stopper 62 to the blocking bar 11 causes the rotating part 17 to rotate (pivot), thereby returning the blocking bar 11 to its initial position. That is, in this embodiment, the opening and closing of the blocking bar 11 and the return of the rotating part 17 can be performed by one electric motor 51. In this case, the opening and closing electric motor also serves as the return electric motor.

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

[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 unit 17 positions the blocking bar 11 in the closed position Sc at the open position So, it rotates the rotating shaft 15 so that the blocking bar 11 in the closed position Sc starts to rotate upward in the vertical direction (+Z direction). When the rotating shaft 15 rotates, the blocking bar 11 rotates along a virtual conical surface centered on the central axis Ac and reaches the open position So. As described above, the blocking bar 11 in the open position So extends horizontally and in the lane direction (±X direction).

[0038] When the blocking rod 11 in the open position So is positioned at the closed position Sc, the rotating unit 17 also rotates the rotating shaft 15 so that the blocking rod 11 in the open position So starts to rotate upward in the vertical direction (toward the +Z direction). Therefore, the rotation direction of the rotating shaft 15 when the blocking rod 11 in the open position So is positioned at the closed position Sc is the opposite direction to the rotation direction of the rotating shaft 15 when the blocking rod 11 in the closed position Sc is positioned at the open position So. When the rotating shaft 15 rotates, the blocking rod 11 rotates along a virtual conical surface centered on the central axis Ac, and reaches the closed position Sc again.

[0039] Also, for example, when a vehicle C traveling on lane R hits the blocking bar 11 in the closed position Sc and a load of a predetermined level or more is applied to the blocking bar 11 in the horizontal direction and toward the downstream side in the lane direction (+X direction), the rotating part 17 rotates. Then, the rotating part 17 rotates until the blocking bar 11 hits the burst stopper 62, and the blocking bar 11 moves to the release position Sr. Note that even if the blocking bar 11 does not hit the burst stopper 62, the blocking bar 11 can move until it hits the burst stopper 62 by performing a return operation (opening operation), and perform the above-mentioned return operation. In addition, after the blocking bar 11 hits the burst stopper 62, a bouncing prevention mechanism such as a holding mechanism for preventing the blocking bar 11 from bouncing back may be provided on the burst stopper 62 so that the blocking bar 11 does not bounce back toward the lane R side and damage, for example, the vehicle C. In addition, in order to prevent the blocking bar 11 from remaining in the lane R when released, the rotation mechanism 63 may be provided with a mechanism for rotating the blocking bar 11 by a spring or the like until it hits the burst stopper 62.

[0040] As described above, in this embodiment, the blocking bar 11 rotates along a virtual conical surface centered on the central axis Ac extending in the horizontal direction with the rotation of the rotating shaft 15. In addition, the blocking bar 11 in the closed position Sc extends horizontally and in the lane width direction (±Y direction). For this reason, in this embodiment, as shown in FIG. 5, when the blocking bar 11 in the closed position Sc is displaced to the open position So, the blocking 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, and instead the amount of displacement in the lane width direction (±Y direction) and the lane direction (±X direction) increases. Therefore, in this embodiment, the visibility of the opening start movement of the blocking bar 11 in the closed position Sc is increased for the driver of the vehicle C, making it easier for the driver to recognize that passage is possible.

[0041] In addition, in this embodiment, the blocking bar 11 in the open position So extends in a direction in which the horizontal component is larger than the vertical component (±Z direction) and the lane direction component (±X direction) is larger than the lane width direction component (±Y direction), so the driver of the vehicle C has low visibility of the blocking bar 11 in the open position So. Therefore, the driver can pass the starting control device 10 without worrying about the presence of the blocking bar 11.

[0042] In particular, in this embodiment, the blocking bar 11 in the open position So extends in a direction that has no vertical (±Z) components (i.e., extends horizontally), thereby making it possible to reduce the visibility of the blocking bar 11 in the open position So to the driver of the vehicle C.

[0043] Furthermore, in this embodiment, since the blocking bar 11 in the open position So extends in a direction that has no component in the lane width direction (±Y direction), it is possible to prevent the tip 11t of the blocking bar 11 in the open position So from protruding into the lane R.

[0044] As described above, according to this embodiment, when releasing, the blocking bar 11 is released by rotating the rotating part 17, so that even if a bar release (collision) occurs when the opening operation of the blocking bar 11 is halfway through, it is possible to prevent the blocking bar 11 from hitting the ground.

[0045] In addition, in this embodiment, by performing the opening operation, the position of the rotating part 17 is returned to the initial position by utilizing the reaction force that the blocking bar 11 receives from the burst stopper 62, so that a motor for returning can be omitted. Also, by making the rotating part 17 rotate about the central axis line Ar of the rotation shaft 54 ​​perpendicular to the horizontal direction, the blocking bar 11 can be moved horizontally at the time of release to the release position.

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

[0047] In addition, when the rotation 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, the drive shaft 52 of the electric motor 51 is coaxial with the rotating shaft 54, so that the configuration for rotating the rotating part 17 can be easily simplified.

[0048] Furthermore, since the drive shaft 52 and the rotary shaft 54 ​​are connected via the torque limiter 53, it is possible to prevent an overload from being applied to the electric motor 51 and also to adjust the release torque by the torque limiter 53.

[0049] Furthermore, in this embodiment, when the blocking bar 11 comes into contact with the vehicle C, the blocking bar 11 swings in a horizontal plane. Therefore, the load applied to the blocking bar 11 in the horizontal direction and toward the downstream side in the lane direction (+X direction side) during vehicle contact can be effectively released. Therefore, in this embodiment, the load applied to the blocking bar 11 and the parts supporting the blocking bar 11 during vehicle contact can be suppressed, and damage to these parts can be suppressed.

[0050] In addition, 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 is the same as the control for moving the blocking rod 11 from the open position So to the closed position Sc, making it easier to control the rotating part 17.

[0051] Although the embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to the above embodiments. Various additions, modifications, substitutions, partial deletions, etc. are possible within the scope of the conceptual idea and intent of the present invention derived from the contents defined in the claims and their equivalents.

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

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

[0054] (1) The launch controller 10 in the first embodiment is A rotating shaft 15; a rotation mechanism 63 that rotates the rotation shaft 15 around a central axis Ac of the rotation shaft 15; A blocking rod 11 connected to the rotating shaft 15; A rotating unit 17 that is installed on the roadside of the 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 is supported by the rotating unit 17 via the rotation mechanism 63 so that the rotating shaft 15 extends in a horizontal direction, a tip end 15t of the rotating shaft 15 is located downstream in the lane direction relative to a base end 15b of the rotating shaft 15, and 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 so as to be rotatable along a virtual conical surface centered on the central axis Ac in association with the rotation of the rotating shaft 15, and is inclined with respect to the central axis Ac. The rotation mechanism 63 rotates the rotation shaft 15 so as to realize a closed position Sc 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 larger than the vertical component and the lane direction component is larger than the lane width direction component. The rotating portion 17 rotates in response to a predetermined external force applied to the blocking bar 11, and returns to a predetermined initial position from the position after rotation due to the external force due to the reaction force that the blocking bar 11 receives as the rotation mechanism 63 rotates.

[0055] According to this embodiment and the following embodiments, a launch control device that can improve safety in the event of a vehicle collision with the blocking bar 11 can be provided.
