Description
本発明は、道路工事や検問等の現場において、誤って、あるいは意図せず、さらには突破を意図して突入する車両を強制的に停止させ、加えて、さらなる暴走や逃走を阻止するための車両強制停止装置に関する。 The present invention is intended to forcibly stop a vehicle which rushes in a site of road construction, a check, etc. accidentally, unintentionally, or even intended to break, and additionally to prevent further runaway or escape. The present invention relates to a vehicle forced stop device.
道路工事等で車線規制を行っている際には、誤って車両が突入してきた場合に備えて作業者等の安全を確保するため、車両を強制的に停止する手段が必要とされる。従来、車両を強制的に停止させる手段として、鉄柵、セイフティコーン、水ドラム、砂袋等が使用されていたが、近年では、突入した車両の下部に潜り込み、車両の走行をブロックして強制的に停止させる車両強制停止装置が知られている。例えば、特許文献１に記載の車両強制停止装置は、ベース部に立設された車両止め部と、車両止め部から道路面まで伸びる車両乗り上げ部とを備え、突入車両の下部に車両乗り上げ部を潜り込ませてテコの原理で車両全部を押し上げつつ車両と一体となり、ベース部下面に設けた摩擦部材や爪部材と路面との摩擦抵抗によって車両を停止させようとするものである。また、特許文献２に記載の車両強制停止装置は、上部及び下部にブレーキパッドを有するＨ形鋼の井桁状フレームに突入車両を乗り上げさせ、車輪を空転させることで停止させようとするものである。 When traffic lane regulation is performed by road construction or the like, a means for forcibly stopping the vehicle is necessary in order to ensure the safety of the operator etc. in case the vehicle rushes in by mistake. In the past, iron fences, safety cones, water drums, sand bags, etc. were used as a means to forcibly stop the vehicle, but in recent years, they have plunged into the lower part of the rushed vehicle to block the vehicle from traveling There is known a vehicle forced stop device for stopping the vehicle. For example, the vehicle forced stop device described in Patent Document 1 includes a vehicle stopping portion provided upright on the base portion and a vehicle riding up portion extending from the vehicle stopping portion to the road surface, and the vehicle riding up portion is provided below the rush vehicle. The entire vehicle is pushed up and pushed up the entire vehicle while being integral with the vehicle and the vehicle is stopped by the frictional resistance between a friction member provided on the lower surface of the base portion and the claw member and the road surface. In addition, the vehicle forced stop device described in Patent Document 2 attempts to stop the vehicle by running the rush vehicle on a well-shaped frame of H-shaped steel having brake pads at the upper and lower portions and causing the wheels to idle. .
ここで、誤侵入した車両の場合は、車両強制停止装置との接触の衝撃等により、運転者も誤侵入に気づいて咄嗟にブレーキを掛けて減速させることが期待できるが、運転者が急病等で心神喪失状態にあったり、ブレーキとアクセルとを踏み間違えたりしていたような状況では、特許文献１に記載の車両強制停止装置では必ずしも有効に停止させることができないおそれがあり、逃走中の犯罪者やテロリスト等が意図的に車両を突入させて検問等の突破を試みるといった状況ではなおさらである。また、車両の前部を乗り上げさせる方式の手段は、前輪駆動車の強制停止には有効であるが、後輪駆動車や四輪駆動車に対しては必ずしも有効ではない。 Here, in the case of a vehicle that has made a mistake, it is expected that the driver also notices the mistake and enters the brake and decelerates due to the impact of contact with the vehicle forced stop device, etc. In a situation in which you are in a state of mental loss or wrong in stepping on a brake and an accelerator, the vehicle forced stop device described in Patent Document 1 may not always be able to effectively stop the vehicle, and you are running away. This is all the more so in situations where criminals and terrorists deliberately plunge the vehicle and try to break through the interrogation. In addition, although the method of running on the front of the vehicle is effective for forced stop of a front wheel drive vehicle, it is not necessarily effective for a rear wheel drive vehicle or a four wheel drive vehicle.
一方、特許文献２に記載の車両強制停止装置は、ブレーキパッドを有するフレーム上に車両全体を乗り上げさせる構成であるから、後輪駆動車や四輪駆動車も含め強制停止の効果は期待できるが、装置自体を少なくとも車両の全長に近い長さの大型のものとせざるを得ない。そのため、保管や輸送、設置、撤去には大きな労力とスペースが必要であり、特に、警察による検問や道路封鎖など迅速な展開・撤収が必要とされる場面には適用しにくい。
本発明は、上記の従来技術に係る問題点に鑑みて創作されたものであり、意図的かそうでないかを問わず、運転者が制動操作を行わずに車両を突入させてきた場合を想定して、後輪駆動車や四輪駆動車を含む車両を強制停止させるとともに、運転者の逃走あるいはさらなる暴走を防いで車両自体を無力化することを課題とし、しかも、可能な限り保管や輸送、設置、撤去に要する労力や時間、スペースが小さく、簡易な構造で低コストな車両強制停止装置を提供することを目的とするものである。 The present invention has been made in view of the problems in the prior art described above, and it is assumed that the driver rushes the vehicle without performing the braking operation, whether intentionally or otherwise. To stop the vehicles including the rear wheel drive vehicle and the four wheel drive vehicle forcibly and prevent the driver's runaway or further runaway to make the vehicle itself ineffective, and also to store and transport as much as possible An object of the present invention is to provide a low-cost vehicle forcible stop with a simple structure and requiring a small amount of labor, time and space required for installation and removal.
上記の目的を達成するために、本発明の請求項１に記載した車両強制停止装置は、分離可能に合体させた第１車両支持体と、該第１車両支持体よりも最大地上高が低い第２車両支持体とから成り、前記第１車両支持体は、車両の進行方向に向けて上方に傾斜する第１傾斜部と該第１傾斜部の前方に立設された衝突部とを備え、前記第２車両支持体は、車両の進行方向に向けて上方に傾斜する第２傾斜部を備え、かつ、いずれの車両支持体の最大地上高も少なくとも支持された車両の車輪が路面と接触しない高さを有するよう構成したことを特徴とする。 In order to achieve the above object, a vehicle forcible stop according to claim 1 of the present invention has a first vehicle support that is releasably combined, and a maximum height above the first vehicle support is lower than that of the first vehicle support. The vehicle support comprises a second vehicle support, and the first vehicle support comprises a first inclined portion inclined upward in the traveling direction of the vehicle, and a collision portion provided in front of the first inclined portion. The second vehicle support includes a second inclined portion that inclines upward in the traveling direction of the vehicle, and a wheel of the vehicle supported at least the maximum ground height of any vehicle support contacts the road surface It is characterized in that it is configured to have a height which does not have a height.
本発明に係る車両強制停止装置は、第１車両支持体と第２車両支持体とを合体させて路上等に設置するが、特段路面に固定は行わない。第１車両支持体は第２車両支持体よりも最大地上高が高いため、突入してきた車両が車両強制停止装置に接触すると、まず、車両の前部が第１車両支持体の第１傾斜部に乗り上げ、そのまま衝突部に衝突する。この際、第１傾斜部の最大地上高は少なくとも支持された車両の車輪が路面と接触しない高さを有するため、車両の両前輪は路面から離れて空転状態となる。また、車両強制停止装置は路面に対して固定されていないため、衝突された第１車両支持体は車両の前部を載せたまま一体となって前進を続ける。 In the vehicle forcible stop device according to the present invention, the first vehicle support and the second vehicle support are combined and installed on a road or the like, but the vehicle is not particularly fixed to the road surface. Since the first vehicle support has a maximum ground clearance higher than the second vehicle support, when the rushing vehicle contacts the vehicle forced stop device, the front of the vehicle first becomes the first inclined portion of the first vehicle support Ride on, and collide with the collision part as it is. At this time, since the maximum ground height of the first inclined portion has a height such that at least the wheels of the supported vehicle do not contact the road surface, both front wheels of the vehicle are idled away from the road surface. In addition, since the vehicle forcible stop device is not fixed to the road surface, the collided first vehicle support integrally continues to move forward with the front portion of the vehicle mounted thereon.
一方、第２車両支持体は、第１車両支持体よりも最大地上高が低く、第１車両支持体と車両との接触時点では車両前部の下面には接触しないため、車両とともに前進する第１車両支持体から取り残されてそのまま設置位置に留まる。しかし、第２車両支持体の最大地上高も車両の最低地上高よりは高いため、前部を持ち上げた車両の前進により、車両全長の中央部から後輪軸の手前のいずれかの位置において車両の下面が第２傾斜部に接触して第２車両支持体に乗り上げ、車両の両後輪も路面から離れて空転状態となる。 On the other hand, the second vehicle support has a lower maximum ground height than the first vehicle support and does not contact the lower surface of the front of the vehicle at the time of contact between the first vehicle support and the vehicle. 1 Left behind from the vehicle support and remain at the installed position. However, since the maximum ground height of the second vehicle support is also higher than the minimum ground height of the vehicle, the forward movement of the vehicle with the front lifted raises the vehicle at any position from the center of the entire vehicle length to the front of the rear wheel axle. The lower surface comes in contact with the second inclined portion and rides on the second vehicle support, and both rear wheels of the vehicle move away from the road surface and become idle.
以上により、車両はその前後輪ともに宙に浮いて空転状態となるため、たとえ運転者が接触後にアクセルを踏み続けたとしても車両は駆動力を失っており、慣性によってのみ前進する車両は、路面と第１及び第２の車両支持体の下面との摩擦により減速し、強制的に停止させられるのである。 As described above, the vehicle floats in the air with both the front and rear wheels floating, so even if the driver continues to step on the accelerator after contact, the vehicle loses the driving force, and the vehicle advancing only by inertia is the road surface. It is decelerated and forced to stop by the friction between the lower and the lower surfaces of the first and second vehicle supports.
第１及び第２の車両支持体は、車両の接触による衝撃に耐えるとともに、双方合わせて全車重を支える必要があるが、鋼管を溶接して構成することで十分な強度を実現可能であり、また、第１傾斜部、第２傾斜部並びに衝突部も曲げ加工した鋼管で形成可能である。また、２つの車両支持体を分離可能に合体する構造は、第１車両支持体の平面を進行方向から後方に向けて開く略コの字型に形成して第２車両支持体をその内部に収容可能とすることで実現できる。なお、車両強制停止装置の大きさは、想定する車両のタイプや車重に応じて適宜設計可能であるが、進行方向に対する幅は、車両のトレッド（車軸幅）に余裕をもって収まる範囲とすることが望ましい。トレッドに比べて車両支持体の幅が狭すぎると、乗り上げた車両が横転する可能性が高まり、逆に広すぎると車両支持体が車両の車軸間に適切に侵入しないおそれが高まるからである。また、第１、第２の傾斜面の最大地上高については想定する車両のサスペンションのストロークを考慮して設定する。車両の最低地上高以上の高さであっても、車両が車両支持体に乗り上げてサスペンションが伸長することで、なお車輪が路面に接して駆動力を発揮する場合があるからである。 The first and second vehicle supports need to withstand the impact of contact with the vehicle and together need to support the entire vehicle weight, but sufficient strength can be realized by welding and forming steel pipes, Further, the first inclined portion, the second inclined portion, and the collision portion can also be formed of a bent steel pipe. In addition, the structure for separably combining the two vehicle supports is such that the plane of the first vehicle support is formed in a substantially U-shape opening rearward from the traveling direction, and the second vehicle support is incorporated therein. It can be realized by being able to be accommodated. Although the size of the vehicle forced stop device can be appropriately designed according to the type and weight of the vehicle assumed, the width with respect to the traveling direction should be within a range that fits within the tread (axle width) of the vehicle with a margin. Is desirable. If the width of the vehicle support is too narrow compared to the tread, the possibility of the rolled-up vehicle rolling over increases, and if it is too wide, there is a high possibility that the vehicle support will not properly intrude between the vehicle axles. Further, the maximum ground heights of the first and second slopes are set in consideration of the assumed stroke of the suspension of the vehicle. Even if the height is higher than the lowest ground level of the vehicle, the wheels may come in contact with the road surface and exert a driving force by the vehicle riding on the vehicle support and the suspension extending.
次に、請求項２に係る発明は、請求項１に記載した車両強制停止装置において、第１車両支持体と第２車両支持体とを締結する索体を付加した構成である。車両の前部が第１車両支持体に乗り上げて前進した際に、車両のバウンド等の挙動によって車両の後部が第２車両支持体にうまく乗り上げなかった場合、第２車両支持体はそのまま路面に取り残されてしまい、車両の後輪の駆動力が失われないために強制停止に失敗する可能性がある。ここで、車両のホイールベース（前後車軸間距離）程度の長さのロープ等の索体で両車両支持体を締結しておくことにより、第２車両支持体は前進する第１車両支持体に牽引されて車両下面の後輪軸付近に位置することとなり、最終的に車両後部を乗り上げさせることができる。 Next, the invention according to claim 2 is the vehicle forcible stop device according to claim 1, wherein a rope for fastening the first vehicle support and the second vehicle support is added. When the front of the vehicle gets on the first vehicle support and moves forward, if the rear of the vehicle does not get on the second vehicle support well due to the behavior of the vehicle, etc., the second vehicle support remains on the road surface It may be left behind, and the forced stop may fail because the driving force of the rear wheels of the vehicle is not lost. Here, the second vehicle support is a first vehicle support that moves forward by fastening both vehicle supports with a rope or other rope body or the like having a length about the wheel base (distance between front and rear axles) of the vehicle. It will be towed and located near the rear wheel axle on the lower surface of the vehicle, and can finally ride on the rear of the vehicle.
次に、請求項３に係る発明は、請求項１又は請求項２のいずれかに記載の車両強制停止装置であって、前記衝突部の進行方向側に複数のキャスターを設け、合体時の第１車両支持体と第２車両支持体を進行方向に９０°転回させた状態において前記キャスターにて接地するよう構成したことを特徴とする。かかる構成により、車両強制停止装置全体を前方に９０°倒してキャスターを接地させれば手押しで容易に設置位置に移動させることができ、設置場所では後方に９０°引き起こすだけで設置が完了するから、展開や撤収が迅速に行える。 Next, the invention according to claim 3 is the vehicle forced stop device according to any one of claim 1 or claim 2, wherein a plurality of casters are provided on the traveling direction side of the collision part, and The first invention is characterized in that the caster contacts the ground in a state where the vehicle support and the second vehicle support are turned 90 ° in the traveling direction. With this configuration, the entire vehicle forcible stop can be turned forward by 90 ° to ground the casters, and the caster can be easily moved to the installation position by hand, and the installation location is completed only by causing 90 ° backward. , Deployment and withdrawal can be done quickly.
請求項１に係る車両強制停止装置によれば、前輪駆動車だけでなく後輪駆動車や四輪駆動車を含む車両を強制停止させるだけでなく、最悪、運転者が逃走あるいはさらなる暴走を図ろうとしても、車両自体を効果的に無力化できる。また、請求項２の発明に係る索体を付加することにより、バウンド等により車両の最低地上高が第２車両支持体の高さを超える状態となったとしても、最終的には車両の後部が第２車両支持体に乗り上げて全輪が空転状態となるため、強制停止の確実性を向上できる。さらに、請求項３の発明に係るキャスターを付加することにより、車両強制停止装置の移動が容易となり、迅速な展開及び撤収が可能となる。 According to the vehicle forcible stop device according to claim 1, not only forced-stopping not only front-wheel drive vehicles but also vehicles including rear-wheel drive vehicles and four-wheel drive vehicles, in the worst case, the driver escapes or further runs away However, the vehicle itself can be effectively disabled. In addition, by adding the cable according to the invention of claim 2, even if the minimum ground clearance of the vehicle exceeds the height of the second vehicle support due to bounce or the like, the rear of the vehicle is finally obtained. However, since the vehicle rides on the second vehicle support and all the wheels become idle, the certainty of forced stop can be improved. Furthermore, by adding the caster according to the invention of claim 3, movement of the vehicle forced stop device becomes easy, and rapid deployment and withdrawal become possible.

At this time, the left and right combined pipes 25 of the second vehicle support 2 are pulled out from the tip of the horizontal portion 13 of the main frame 10 of the first vehicle support 1, and the two vehicle supports are separated. Is left behind. When the test vehicle in a state where the front of the vehicle body is lifted further advances, the lower surface of the vehicle body is brought into contact with the second inclined portion 22 of the second vehicle support 2 near the front of the rear wheel axle and lifted up.

本発明は、道路工事や検問等の現場において、誤って、あるいは意図せず、さらには突破を意図して突入する車両を強制的に停止させ、加えて、さらなる暴走や逃走を阻止するための車両強制停止装置に関する。 The present invention is intended to forcibly stop a vehicle which rushes in a site of road construction, a check, etc. accidentally, unintentionally, or even intended to break, and additionally to prevent further runaway or escape. The present invention relates to a vehicle forced stop device.
道路工事等で車線規制を行っている際には、誤って車両が突入してきた場合に備えて作業者等の安全を確保するため、車両を強制的に停止する手段が必要とされる。従来、車両を強制的に停止させる手段として、鉄柵、セイフティコーン、水ドラム、砂袋等が使用されていたが、近年では、突入した車両の下部に潜り込み、車両の走行をブロックして強制的に停止させる車両強制停止装置が知られている。例えば、特許文献１に記載の車両強制停止装置は、ベース部に立設された車両止め部と、車両止め部から道路面まで伸びる車両乗り上げ部とを備え、突入車両の下部に車両乗り上げ部を潜り込ませてテコの原理で車両全部を押し上げつつ車両と一体となり、ベース部下面に設けた摩擦部材や爪部材と路面との摩擦抵抗によって車両を停止させようとするものである。また、特許文献２に記載の車両強制停止装置は、上部及び下部にブレーキパッドを有するＨ形鋼の井桁状フレームに突入車両を乗り上げさせ、車輪を空転させることで停止させようとするものである。 When traffic lane regulation is performed by road construction or the like, a means for forcibly stopping the vehicle is necessary in order to ensure the safety of the operator etc. in case the vehicle rushes in by mistake. In the past, iron fences, safety cones, water drums, sand bags, etc. were used as a means to forcibly stop the vehicle, but in recent years, they have plunged into the lower part of the rushed vehicle to block the vehicle from traveling There is known a vehicle forced stop device for stopping the vehicle. For example, the vehicle forced stop device described in Patent Document 1 includes a vehicle stopping portion provided upright on the base portion and a vehicle riding up portion extending from the vehicle stopping portion to the road surface, and the vehicle riding up portion is provided below the rush vehicle. The entire vehicle is pushed up and pushed up the entire vehicle while being integral with the vehicle and the vehicle is stopped by the frictional resistance between a friction member provided on the lower surface of the base portion and the claw member and the road surface. In addition, the vehicle forced stop device described in Patent Document 2 attempts to stop the vehicle by running the rush vehicle on a well-shaped frame of H-shaped steel having brake pads at the upper and lower portions and causing the wheels to idle. .
ここで、誤侵入した車両の場合は、車両強制停止装置との接触の衝撃等により、運転者も誤侵入に気づいて咄嗟にブレーキを掛けて減速させることが期待できるが、運転者が急病等で心神喪失状態にあったり、ブレーキとアクセルとを踏み間違えたりしていたような状況では、特許文献１に記載の車両強制停止装置では必ずしも有効に停止させることができないおそれがあり、逃走中の犯罪者やテロリスト等が意図的に車両を突入させて検問等の突破を試みるといった状況ではなおさらである。また、車両の前部を乗り上げさせる方式の手段は、前輪駆動車の強制停止には有効であるが、後輪駆動車や四輪駆動車に対しては必ずしも有効ではない。 Here, in the case of a vehicle that has made a mistake, it is expected that the driver also notices the mistake and enters the brake and decelerates due to the impact of contact with the vehicle forced stop device, etc. In a situation in which you are in a state of mental loss or wrong in stepping on a brake and an accelerator, the vehicle forced stop device described in Patent Document 1 may not always be able to effectively stop the vehicle, and you are running away. This is all the more so in situations where criminals and terrorists deliberately plunge the vehicle and try to break through the interrogation. In addition, although the method of running on the front of the vehicle is effective for forced stop of a front wheel drive vehicle, it is not necessarily effective for a rear wheel drive vehicle or a four wheel drive vehicle.
一方、特許文献２に記載の車両強制停止装置は、ブレーキパッドを有するフレーム上に車両全体を乗り上げさせる構成であるから、後輪駆動車や四輪駆動車も含め強制停止の効果は期待できるが、装置自体を少なくとも車両の全長に近い長さの大型のものとせざるを得ない。そのため、保管や輸送、設置、撤去には大きな労力とスペースが必要であり、特に、警察による検問や道路封鎖など迅速な展開・撤収が必要とされる場面には適用しにくい。
本発明は、上記の従来技術に係る問題点に鑑みて創作されたものであり、意図的かそうでないかを問わず、運転者が制動操作を行わずに車両を突入させてきた場合を想定して、後輪駆動車や四輪駆動車を含む車両を強制停止させるとともに、運転者の逃走あるいはさらなる暴走を防いで車両自体を無力化することを課題とし、しかも、可能な限り保管や輸送、設置、撤去に要する労力や時間、スペースが小さく、簡易な構造で低コストな車両強制停止装置を提供することを目的とするものである。 The present invention has been made in view of the problems in the prior art described above, and it is assumed that the driver rushes the vehicle without performing the braking operation, whether intentionally or otherwise. To stop the vehicles including the rear wheel drive vehicle and the four wheel drive vehicle forcibly and prevent the driver's runaway or further runaway to make the vehicle itself ineffective, and also to store and transport as much as possible An object of the present invention is to provide a low-cost vehicle forcible stop with a simple structure and requiring a small amount of labor, time and space required for installation and removal.
上記の目的を達成するために、本発明の請求項１に記載した車両強制停止装置は、合体手段を介して相互を固定することなく分離可能に合体させた第１車両支持体と、該第１車両支持体よりも最大地上高が低い第２車両支持体とから成り、前記第１車両支持体は、車両の進行方向に向けて上方に傾斜する第１傾斜部と該第１傾斜部の前方に立設された衝突部とを備え、前記第２車両支持体は、車両の進行方向に向けて上方に傾斜する第２傾斜部を備え、かつ、いずれの車両支持体の最大地上高も少なくとも支持された車両の車輪が路面と接触しない高さを有するよう構成したことを特徴とする。 To achieve the above object, a vehicle suspended apparatus according to claim 1 of the present invention includes a first vehicle support having detachably coalesced without fixing the each other through the coalescing means, said (1) A second vehicle support having a maximum ground height lower than that of the vehicle support, the first vehicle support comprising a first inclined portion inclined upward in the traveling direction of the vehicle and a portion of the first inclined portion And a second inclined portion which is inclined upward in the traveling direction of the vehicle, and the maximum ground height of any of the vehicle supports is the same. It is characterized in that at least the supported wheels of the vehicle have a height that does not come in contact with the road surface.
本発明に係る車両強制停止装置は、第１車両支持体と第２車両支持体とを合体させて路上等に設置するが、特段路面に固定は行わない。第１車両支持体は第２車両支持体よりも最大地上高が高いため、突入してきた車両が車両強制停止装置に接触すると、まず、車両の前部が第１車両支持体の第１傾斜部に乗り上げ、そのまま衝突部に衝突する。この際、第１傾斜部の最大地上高は少なくとも支持された車両の車輪が路面と接触しない高さを有するため、車両の両前輪は路面から離れて空転状態となる。また、車両強制停止装置は路面に対して固定されていないため、衝突された第１車両支持体は車両の前部を載せたまま一体となって前進を続ける。 In the vehicle forcible stop device according to the present invention, the first vehicle support and the second vehicle support are combined and installed on a road or the like, but the vehicle is not particularly fixed to the road surface. Since the first vehicle support has a maximum ground clearance higher than the second vehicle support, when the rushing vehicle contacts the vehicle forced stop device, the front of the vehicle first becomes the first inclined portion of the first vehicle support Ride on, and collide with the collision part as it is. At this time, since the maximum ground height of the first inclined portion has a height such that at least the wheels of the supported vehicle do not contact the road surface, both front wheels of the vehicle are idled away from the road surface. In addition, since the vehicle forcible stop device is not fixed to the road surface, the collided first vehicle support integrally continues to move forward with the front portion of the vehicle mounted thereon.
一方、第２車両支持体は、第１車両支持体よりも最大地上高が低く、第１車両支持体と車両との接触時点では車両前部の下面には接触しないため、車両とともに前進する第１車両支持体から取り残されてそのまま設置位置に留まる。しかし、第２車両支持体の最大地上高も車両の最低地上高よりは高いため、前部を持ち上げた車両の前進により、車両全長の中央部から後輪軸の手前のいずれかの位置において車両の下面が第２傾斜部に接触して第２車両支持体に乗り上げ、車両の両後輪も路面から離れて空転状態となる。 On the other hand, the second vehicle support has a lower maximum ground height than the first vehicle support and does not contact the lower surface of the front of the vehicle at the time of contact between the first vehicle support and the vehicle. 1 Left behind from the vehicle support and remain at the installed position. However, since the maximum ground height of the second vehicle support is also higher than the minimum ground height of the vehicle, the forward movement of the vehicle with the front lifted raises the vehicle at any position from the center of the entire vehicle length to the front of the rear wheel axle. The lower surface comes in contact with the second inclined portion and rides on the second vehicle support, and both rear wheels of the vehicle move away from the road surface and become idle.
以上により、車両はその前後輪ともに宙に浮いて空転状態となるため、たとえ運転者が接触後にアクセルを踏み続けたとしても車両は駆動力を失っており、慣性によってのみ前進する車両は、路面と第１及び第２の車両支持体の下面との摩擦により減速し、強制的に停止させられるのである。 As described above, the vehicle floats in the air with both the front and rear wheels floating, so even if the driver continues to step on the accelerator after contact, the vehicle loses the driving force, and the vehicle advancing only by inertia is the road surface. It is decelerated and forced to stop by the friction between the lower and the lower surfaces of the first and second vehicle supports.
第１及び第２の車両支持体は、車両の接触による衝撃に耐えるとともに、双方合わせて全車重を支える必要があるが、鋼管を溶接して構成することで十分な強度を実現可能であり、また、第１傾斜部、第２傾斜部並びに衝突部も曲げ加工した鋼管で形成可能である。また、２つの車両支持体を分離可能に合体する構造は、第１車両支持体の平面を進行方向から後方に向けて開く略コの字型に形成して第２車両支持体をその内部に収容可能とすることで実現できる。なお、車両強制停止装置の大きさは、想定する車両のタイプや車重に応じて適宜設計可能であるが、進行方向に対する幅は、車両のトレッド（車軸幅）に余裕をもって収まる範囲とすることが望ましい。トレッドに比べて車両支持体の幅が狭すぎると、乗り上げた車両が横転する可能性が高まり、逆に広すぎると車両支持体が車両の車軸間に適切に侵入しないおそれが高まるからである。また、第１、第２の傾斜面の最大地上高については想定する車両のサスペンションのストロークを考慮して設定する。車両の最低地上高以上の高さであっても、車両が車両支持体に乗り上げてサスペンションが伸長することで、なお車輪が路面に接して駆動力を発揮する場合があるからである。 The first and second vehicle supports need to withstand the impact of contact with the vehicle and together need to support the entire vehicle weight, but sufficient strength can be realized by welding and forming steel pipes, Further, the first inclined portion, the second inclined portion, and the collision portion can also be formed of a bent steel pipe. In addition, the structure for separably combining the two vehicle supports is such that the plane of the first vehicle support is formed in a substantially U-shape opening rearward from the traveling direction, and the second vehicle support is incorporated therein. It can be realized by being able to be accommodated. Although the size of the vehicle forced stop device can be appropriately designed according to the type and weight of the vehicle assumed, the width with respect to the traveling direction should be within a range that fits within the tread (axle width) of the vehicle with a margin. Is desirable. If the width of the vehicle support is too narrow compared to the tread, the possibility of the rolled-up vehicle rolling over increases, and if it is too wide, there is a high possibility that the vehicle support will not properly intrude between the vehicle axles. Further, the maximum ground heights of the first and second slopes are set in consideration of the assumed stroke of the suspension of the vehicle. Even if the height is higher than the lowest ground level of the vehicle, the wheels may come in contact with the road surface and exert a driving force by the vehicle riding on the vehicle support and the suspension extending.
次に、請求項２に係る発明は、請求項１に記載した車両強制停止装置において、第１車両支持体と第２車両支持体とを締結する索体を付加した構成である。車両の前部が第１車両支持体に乗り上げて前進した際に、車両のバウンド等の挙動によって車両の後部が第２車両支持体にうまく乗り上げなかった場合、第２車両支持体はそのまま路面に取り残されてしまい、車両の後輪の駆動力が失われないために強制停止に失敗する可能性がある。ここで、車両のホイールベース（前後車軸間距離）程度の長さのロープ等の索体で両車両支持体を締結しておくことにより、第２車両支持体は前進する第１車両支持体に牽引されて車両下面の後輪軸付近に位置することとなり、最終的に車両後部を乗り上げさせることができる。 Next, the invention according to claim 2 is the vehicle forcible stop device according to claim 1, wherein a rope for fastening the first vehicle support and the second vehicle support is added. When the front of the vehicle gets on the first vehicle support and moves forward, if the rear of the vehicle does not get on the second vehicle support well due to the behavior of the vehicle, etc., the second vehicle support remains on the road surface It may be left behind, and the forced stop may fail because the driving force of the rear wheels of the vehicle is not lost. Here, the second vehicle support is a first vehicle support that moves forward by fastening both vehicle supports with a rope or other rope body or the like having a length about the wheel base (distance between front and rear axles) of the vehicle. It will be towed and located near the rear wheel axle on the lower surface of the vehicle, and can finally ride on the rear of the vehicle.
次に、請求項３に係る発明は、請求項１又は請求項２のいずれかに記載の車両強制停止装置であって、前記衝突部の進行方向側に複数のキャスターを設け、合体時の第１車両支持体と第２車両支持体を進行方向に９０°転回させた状態において前記キャスターにて接地するよう構成したことを特徴とする。かかる構成により、車両強制停止装置全体を前方に９０°倒してキャスターを接地させれば手押しで容易に設置位置に移動させることができ、設置場所では後方に９０°引き起こすだけで設置が完了するから、展開や撤収が迅速に行える。 Next, the invention according to claim 3 is the vehicle forced stop device according to any one of claim 1 or claim 2, wherein a plurality of casters are provided on the traveling direction side of the collision part, and The first invention is characterized in that the caster contacts the ground in a state where the vehicle support and the second vehicle support are turned 90 ° in the traveling direction. With this configuration, the entire vehicle forcible stop can be turned forward by 90 ° to ground the casters, and the caster can be easily moved to the installation position by hand, and the installation location is completed only by causing 90 ° backward. , Deployment and withdrawal can be done quickly.
請求項１に係る車両強制停止装置によれば、前輪駆動車だけでなく後輪駆動車や四輪駆動車を含む車両を強制停止させるだけでなく、最悪、運転者が逃走あるいはさらなる暴走を図ろうとしても、車両自体を効果的に無力化できる。また、請求項２の発明に係る索体を付加することにより、バウンド等により車両の最低地上高が第２車両支持体の高さを超える状態となったとしても、最終的には車両の後部が第２車両支持体に乗り上げて全輪が空転状態となるため、強制停止の確実性を向上できる。さらに、請求項３の発明に係るキャスターを付加することにより、車両強制停止装置の移動が容易となり、迅速な展開及び撤収が可能となる。 According to the vehicle forcible stop device according to claim 1, not only forced-stopping not only front-wheel drive vehicles but also vehicles including rear-wheel drive vehicles and four-wheel drive vehicles, in the worst case, the driver escapes or further runs away However, the vehicle itself can be effectively disabled. In addition, by adding the cable according to the invention of claim 2, even if the minimum ground clearance of the vehicle exceeds the height of the second vehicle support due to bounce or the like, the rear of the vehicle is finally obtained. However, since the vehicle rides on the second vehicle support and all the wheels become idle, the certainty of forced stop can be improved. Furthermore, by adding the caster according to the invention of claim 3, movement of the vehicle forced stop device becomes easy, and rapid deployment and withdrawal become possible.
